A problem - Assignment Example In so doing, Harry’s mother had a chance of knowing the events taking place in the school. In this case, I would visit Harry’s mother to inquire about her attendance on the school party. This would be helpful in that, Harry mother would confirm her attendance. However, Harry would have issue with that since he would feel am interfering with his affairs. Secondly, I would also inform Harry that his mother have confirmed her attendance to the party. In so doing, Harry would not have a choice to agree and if he disagrees, I would inform Harry on the benefit of appreciating his mother just the way she is. The drawback of this solution is that it would increase many conflicts as harry tries to justify why he does not want to come with his mother. Harry has problems with his mother appearance, speech, and mannerism. I feel that the problem developed because of torn invitation. The invitation causes Harry to express his negative thoughts about his mother. I think the problem could be avoided If Harry was given the chance to choose what he wants. Also, it would be helpful if all students were promised a reward if they come with their parents. In this essay, we will discuss a couple that encountered the problem of infertility in their marriage. Early last year, a young couple in Mountain View village encountered a big problem that affected them emotionally and psychologically. The couple desired to bear children, but they were incapable of having one. Despite being in love with each, the couple encountered a lot of criticism especially from parents. Often, the man was told that he is not a man enough since he married a woman who cannot bear him a child. In many gatherings, the woman was told that she is useless and does not deserve to live since she could not bear a child. Day by day, the couple became frustrated and worried because of the problem they were undergoing. In spite of the criticisms and rejection from the family members and the society, the

Discussion on the importance of classroom management

Discussion on the importance of classroom management The main question that goes through every teacher after each of his or her lesson would certainly be, Have I done my job effectively? Normally, I can tell whether a lesson has gone well or the opposite. As much as I love sharing knowledge with my students, my experience of merely two years of college teaching has taught myself that it must go hand-in-hand with good management of my classroom. Good classroom management translates into effective teaching which promotes healthy teaching and learning environment. This, in turn, will facilitate both students and teacher in achieving the main principle of learning. Although classroom management would generally be imperative to teachers, a research by Fowler Ã…Å ¾araplÄÂ ± (2010) found that it is also important to students. Therefore it is a significant skill that teachers should acquire (Stoughton, 2007). Classroom management is important primarily in achieving optimal learning. Current teaching practices are more student-oriented where in due course the students will get the most out of the teaching and learning process. This is accomplished by creating a positive learning environment for the students. Students learn best when they are comfortable with their surroundings especially through the building of strong student-teacher relationship. In an article by Marzano Marzano (2003), they highlighted the finding of their study which indicates that the teachers who had a good relationship with their students had 31 percent fewer discipline problems, rule violations and related problems over a years time compared to those who didnt. This provides evidence that strong student-teacher bonding helps the teacher in dealing with problems and misbehaviour among students. By building a strong relationship with students, the positive learning environment has taken place and so the teachers can expect active participation in class. The last thing a teacher would want is when he or she is hoping for a response from the students, but didnt receive any. I found it very useful to remember the names of each of my students and I would try my best to identify each of them by the end of first month class meeting. I discovered that it is an excellent way in obtaining students involvement in class. In a way, I wanted to show that they are of significant individuals to me and also there is no favouritism in my class where the teacher will only remember two or three names of selected few. The students will usually be more proactive to give their thoughts and feedbacks during and after lessons. Subsequently, I will know how effective my teaching has been and how effective the learning has taken place. Students and teacher can be thought of as a team where teamwork and cooperation plays a vital role in achieving team goals. This cooperation can be obtained with the teachers good management skills in the classroom. The teacher will need the support from his or her students in order to deliver lesson on his or her best effort. Therefore, students cooperation in avoiding any misconduct during lessons is much needed by the teacher. Of course the teacher should be firm in handling these kinds of behaviour, but prevention is better than cure. I would try as much as possible to avoid using anger as a counter measure because it will end up straining the relationship built with the students. Ultimately to steer clear of the situation, I know that it is best to tell the students first hand of what I deem is acceptable and what is not. In addition to helping the teacher doing his or her job effectively, students cooperation developed through classroom management can also mould students into young citizens. Metzger (2000) suggests that in a democratic society, the teacher can use classroom management strategies to define the students as good citizens in the near future. This can be done by bringing up the concept of power sharing. The students will be given responsibilities on their own behaviour and making their own decisions, not just following orders. This will also benefit the teachers in a sense that they will feel less pressured because of the constant need of monitoring the students. In fact, they can have the opportunity to really work together with their students. Adequate preparations and properly lay out plans of conducting lessons is also a form of classroom management that is important in designing a positive classroom climate. A positive classroom climate is another key benefit of true classroom management. Checking the overall condition of the classroom before meeting the students is very important to make sure that the facilities provided can be used as effective teaching aids. The teacher can also anticipate potential problems that may occur during lessons due to uncomfortable settings in the classroom. Instead of just cancelling class and replacing them, the teacher can plan ahead what could be done or has a backup plan in case something didnt go as initially planned. This will greatly improve the teachers teaching in the future and gaining experience in managing future classes. Finally, classroom management is also a good way to get off to a right start with students. First day of class is the best time to communicate rules and procedures, explaining the syllabus and expectations. Some teachers will also begin the first day of class with ice-breakers or fun activities so that the students feel excited and will look forward to attending future meetings. It also creates opportunity for the teacher and students to get to know each other better which will help in building quality student-teacher relationship. Last semester I did an activity which benefited my students and myself, which is identifying what type of learning styles we have. It helped me to tailor fit my teaching approach to suit particular group of students and also helped the students to focus more on their strong points. Conclusively, classroom management is important because it is one of the aspects of effective teaching. Effective teaching will take place when a positive learning environment has been created. Of course this relies on a good bond between the students and the teacher which can be built with a proper management of the first day of class. By clearly stating the rules and teachers expectations of the students, the teacher will find no problem in obtaining students engagement in class. Proper classroom management is of great importance to the students, as it is for the teachers. At the end of the day, hopefully after successfully implementing classroom management strategies, the teacher can safely say, Yes, I have done my job effectively.

Human Culture and its Effects on Technology Essay -- Technology Techno

Human Culture and its Effects on Technology A fluid border exists between the influences of culture and technology on the environment. Culture is generally defined as the predominating modes of thinking and behaving that characterize the workings of a group, while technology is the collection of knowledge available to a society that aids it in crafting tools, practicing arts and skills, and extracting or accumulating materials. In some instances, a people's culture drives its pursuit of more highly advanced technologies, while in other cases the implementation of newfound technology alters and shapes culture. These relationships are clearly visible throughout the course of human history. This paper focuses on the effects of early human culture on the progress of technological advances. Some cultural developments with significant impacts on human technology that are especially of note are religion, warfare, and the value system of wealth. George Basalla writes that "necessity spurs on inventive effort" (6). Humans develop technology to meet their perceived needs, though need is a relative term. Technology may serve entirely different purposes within various groups of people, which indicates that it obtains its importance within a specific cultural framework (Basalla 12). Some cultures developed religion and brought it into their lives, which in turn yielded new technological innovation. Great intellectual leaps are also considered technology, and religion encouraged one of the most important: a system of writing. Writing is believed to have developed alongside religious practices, due to the necessity of timing rituals. This need brought the calendar into the world, as well as a new system of communication (Ehrlich 224). Writ... ...an culture has proven itself to be highly influential in the progress of technology. From key aspects of early culture, including religion, war, and concepts of wealth, have stemmed great technological achievements that have forever altered the culture of today.

Chick Lit Genre Analysis

A protagonist in a chick lit book is typically a self-critical female with unreasonably high expectations. In â€Å"24-Karat Kids†, a novel by Dr. Judy Goldstein and Sebastian Stuart, Shelley is hired as a pediatrician at a ritzy Upper East Side office. She quickly realizes that she doesn’t look like the other women that work, or visit the office everyday. She’s very critical of her own appearance, â€Å"Staring back at me was a plain, tubby young woman with an absurdly garish scarf around her neck† (Goldstein 12). Shelly isn’t built like the other females and wasn’t raised wealthy. She is unreasonable to expect herself to look exactly like the others and fit in instantly. She critiques her body in every mirror she passes and quickly adopts a strict diet: â€Å"I’d been on the only diet that worked for me: starvation† (Goldstein 30). In order to fit her unreasonably high expectation of achieving the â€Å"perfect† body, she goes to extreme lengths. Shelley has been in a serious relationship for over two years with a man named Arthur. He has a secure job, is kind and compassionate and has recently proposed. The two begin apartment hunting and stumble upon a nice unit in Brooklyn. Shelly used to love Brooklyn before she started her new job. When Arthur pressures her to share her opinion on the apartment she wonders, â€Å"Why did my mind keep racing back to the Upper East Side, to Dr. Marge and Amanda Walker and Christina Allen, to a world filled with wealth, excitement and glamour† (Goldstein 53). Her current lifestyle just isn’t good enough for her anymore. She wants the luxury her clients and coworkers experience. Although she has a fiance many dream of having and the chance to move in to a comfortable apartment, she can’t settle for anything less than the best. Chick lit books are typically written in first person to allow the protagonist to analyze and share her opinions on all matters. Shelley and her fiance Arthur go apartment hunting a week after Arthur’s proposal. They have never lived together before and Shelley is hesitant to oblige. Arthur is pressuring her to sign a lease and she thinks, â€Å"In many ways I was just beginning my life and the idea of giving up my independence seemed, I don’t know, rushed. Couldn’t it wait until we were married† (Goldstein 30). Since the book is written in first person, Shelley is able to let the reader in on exactly what is going through her head. She doesn’t really want to move in, but can’t tell Arthur that. If she wasn’t able to share her though process with the reader then people would think Shelley was actually okay with this relationship milestone. Later in the week Shelley meets her new boss. She has an image in her head of what she expects the woman will look like but over analyzes her when they meet for the first time anyways: â€Å"she looked as if she should have been out shopping on Madison Avenue. Somewhere in her fifties, she had frosted blonde hair and expert, subtle makeup, and was wearing high heels and a belted magenta jumpsuit that accentuate her tiny waist. Definitely the most glamorous doctor I had ever seen† (Goldstein 14). Shelley describes what people are wearing in excessive detail all the time. She often make a judgment about their personality based on their outward appearance and always shares these with the reader. Her thorough analysis of the other characters allows readers to gain a better understanding of how everyone in the novel interacts.

Embedded system

AbstractionAn Embedded system has become indispensable in our lifes: autos, airplanes, powerplant control systems, telecommunications systems, all contain digital calculating systems with dedicated functionality. Most of them are real-time systems which response to their seasonableness restraints. The seasonableness demand has to run into under influence of unpredictable stochastic behaviour of the system. In this thesis we address stochastic undertaking executing times. In programming of undertakings in real-time systems, it is normally assumed that the undertakings consume their WCET in every supplication. This is a pessimistic premise that is made in order to vouch difficult real-time public presentation. However ; there exist real-time systems that have soft existent clip restraints. The benefit of loosen uping the premises is that more systems are schedulable and, more significantly, systems with a higher burden is schedulable.The end of the undertaking is to:* Implementing Stochastic WCET and the least slack foremost scheduling algorithm in a real-time system simulator. * Experiments should be performed in order to look into by experimentation the benefits in footings of figure of schedulable systems utilizing stochastic wcets compared to utilizing fixed wcets.

Most of them, if non all, are real-time systems, i.e. their responses to stimulations have timeliness restraints. The seasonableness demand has to be met despite some unpredictable, stochastic behaviour of the system.1.2 ObjectiveThe chief aim of this thesis is to develop 1.

Chapter 7, follows decisions from the consequences obtained.Chapter 2BackgroundThis chapter introduces basic constructs and notations needed for understanding the balance of the thesis. Section 2.1 presents the chief constructs of real-time and embedded systems. Section 2.2 presents the constructs of least slack first algorithm and their types.2.1 Real-time and Embedded Systems2.1.1 RTOSReal-time Operating System, an operating system designed to be used in existent clip systems. A Real clip systems has been defined as Any information processing activity or system which has to react to externally generated input stimulations within a finite and specified hold. The basic features of a real-time systems or embedded computing machine systems have been considered. They were: 1. Breadth and complexness 2. Manipulation of existent Numberss 3. Real-time control. 4. Efficient execution. 5. Extreme dependability and safety. Systems, in which the rightness of their operation is defined non merely in footings of functionality but besides in footings of seasonableness, organize the category of real-time systems. Hard Real clip systems: Seasonableness demands may be difficult significance that the misdemeanor of any such demand is non tolerated. In a difficult real-time system, if non all deadlines are guaranteed to be met, the system is said to be unschedulable. To understand, design, predict, and analyze safety critical applications such as works control and aircraft control, hence the community focused on difficult existent clip systems, where interrupting seasonableness demands are non tolerated. The analysis of such system gives a yes/no reply to the inquiry if the system fulfils the seasonableness demands. Hard existent clip analysis relies on constructing worst-case scenarios. Hard existent clip analysis can non afford but to presume that worst instance scenarios ever go on and to proviso for these instances. This attack is the lone one applicable for the category of safety critical embedded systems, even if really frequently leads to important under use of resources. Soft Real clip systems: Systems classified as soft real-time may on occasion interrupt a real-time demand provided that the service quality exceeds prescribed degrees. The nature of real-time embedded system is typically heterogenous along multiple dimensions. For illustration, an application may exhibit informations, control and protocol processing features. It may besides dwell of blocks exhibiting different classs of seasonableness demands, such as difficult and soft. In the instance of soft real-time systems nevertheless, the analysis provides fittingness estimations, such as steps of the grade to which a system is schedulable, instead than binary categorizations.2.1.2 SimulationSimulation is a method which can be used for analysis of response clip. When we are utilizing simulation, a elaborate theoretical account of the system is executed in imitating a system before it is implemented helps cut downing hazards of failure.2.1.3 UndertakingsA procedure in a existent clip system normally with some deadline and a period.2.1.4 Response clipThe clip in which system gives end product after taking input.2.1.5 Worst instance response clipThe maximal possible response clip of a undertaking.2.1.6 Worst instance executing clip ( WCET )The longest possible executing clip of the undertaking. Stochastic theoretical account uses in: It improves schedulability of undertakings compared to presuming their executing times are ever equal to their wcets. It uses good known Techniques of Deterministic Analysis, such as barricading in shared resources, undertaking precedence assignment.2.2 Least slack foremost Scheduling Algorithm:Least Slack Time programming is a Scheduling algorithm. It assigns precedence based on the slack clip of a procedure. It is besides known as Least Laxity First and most common usage is in embedded systems, particularly those with multiple processors.2.2.1 Slack clipThis programming algorithm first selects those procedures that have the smallest â€Å" loose clip † . Slack clip is defined as the temporal difference between the absolute deadline, the ready clip and the tally clip. More officially, the slack clip for a procedure is defined as: ( d – T ) – degree Celsius ‘ Where, vitamin D is the procedure deadline T is the existent clip since the rhythm start degree Celsius ‘ is the staying calculation clip. It ‘s Suitable in: LST programming is most utile in systems consisting chiefly nonperiodic undertakings, because no anterior premises are made on the events ‘ rate of happening. The chief failing of LST is that it does non look in front, and works merely on the current system province. Therefore, during a brief overload of system resources, LST can be sub-optimal and it will besides be suboptimal when used with uninterruptible procedures. It is optimum in: 1. Processor pre-emption is allowed. 2. No contention for resources. 3. Single processor. 4. Arbitrary release times. 5. Arbitrary deadlines.2.2.2 Related plants on LSTWhen an algorithm contains same least loose clip, it causes tonss of unneeded exchanging so bad public presentation will be at that place, so to curtail that we use least slack first to a great extent. LSF scheduling algorithm implemented by threshold ; a fresh Dynamic Fuzzy Threshold Based least Slack First ( DFTLSF ) scheduling algorithm is presented. DFTLSF algorithm uses the lingual set ( uncountable set ) to depict the period and the slack clip which contains unsure characters. The threshold coefficient gotten by fuzzy regulations assigns the threshold of the running undertaking dynamically. Any one who wants to preempt this undertaking must hold the smaller slack clip than the threshold. The consequences of the simulations show that, comparing to the traditional LSF Algorithm, the exchanging figure ( SN ) is much smaller2.2.2.1 DFTLSF Fuzzy Threshold:Two characters are considered to judge the precedence of a undertaking in DFTLSF: 1. Slack Time. 2. Threshold. The most of import of the undertaking to the system is, The little coefficient consequences in the little threshold which causes the difficult pre-emption by other undertakings. Once the undertaking gets the CPU, its slack clip reduces to its pre-emption threshold degree which is computed. It wo n't acquire back until the undertaking is done or the undertaking is preempted by another undertaking. The algorithm integrates the advantages of the pre-emption scheduling algorithm and the non-preemption 1. It consequences in a double precedence system that is good for the undertakings put to deathing successfully and cut downing the exchanging figure. The method makes the agenda and the pre-emption flexible and sensible harmonizing to the state of affairs the undertaking faces. When the threshold coefficient is 0, the algorithm is the method becomes the LSF while the threshold coefficient gets its biggest one which is 1.Scheduling scheme:In DFTLSF scheduling algorithm, the dynamic fuzzed threshold coefficient is proposed. It improves the schedulability by adding a fuzzed threshold coefficient. To look for the threshold coefficient, some fuzzy regulations are made ; the threshold coefficient is used for the running undertakings in the system. It is compared with other undertakings loose clip to make up one's mind which one to run foremost. It decreases the switching figure among undertakings when the slack clip of the undertakings is about the same. As a consequence, it avoids the walloping ( trading ) in the system and improves the schedulability. Another betterment is the critical value of loose clip. It is introduced into the system to guarantee the undertakings which are about finished ca n't be preempted by other undertakings.2.2.2.2 Least Laxity First Scheduling:This can be a coprocessor capable of implementing dynamic programming algorithms which are, until now seldom used because of their complex calculations at agenda clip. LLF is an optimum programming methodological analysis that allows sensing of clip restraint misdemeanors in front of making a tasks deadline, but has the disadvantage of demoing hapless runtime behaviour in some particular state of affairss ( â€Å"thrashing† ) The Least-Laxity-First algorithm ( LLF ) is a dynamic programming method, i.e. it makes the determination about which undertaking to put to death following at schedule clip. Another great advantage of the Least-Laxity-First algorithm is the fact that except schedulability proving no farther analysis, e.g. for delegating fixed precedences to the undertakings, has to be done at development clip. Furthermore, Least-Laxity-First shows hapless public presentation in state of affairss in which more than one undertaking have the smallest slack.2.2.2.3 Enhanced Least Laxity First Scheduling:This algorithm preserves all advantages of LLF while bettering the tally clip behaviour by cut downing the figure of context switches. Calculation clip of this device is instead a affair of clip declaration than of the figure of undertakings. This is of high importance as LLF in certain state of affairss causes a large figure of unneeded context switches that can dramatically increase operating system operating expense. ELLF algorithm represents a inactive programming coprocessor, i.e. the device determines the undertaking to be executed next merely after an external start signal. The purpose of this betterment is to guarantee that in a state of affairs when some undertakings would usually get down to thresh, they are executed consecutively without preempting each other. This can non be done by merely doing the whole system temporarily Non-preemptive. With such a non-preemptive LLF-algorithm, undertakings may lose their deadlines.Advantages of Enhanced Least-Laxity- First Scheduling:1. It responses the clip analysis of threshing undertakings. 2. Number of Context Switches.2.2.2.4 Modified Least Laxity First Scheduling:A Modified Least-Laxity-First ( MLLF ) scheduling algorithm is to work out the frequent context switches job of the LLF programming algorithm. The MLLF programming algorithm allows the laxness inversion where a undertaking with the least laxness may non be scheduled instantly. If the laxity-tie occurs, MLLF scheduling algorithm allows the running undertaking to run with no pre-emption every bit far as the deadlines of other undertakings are non missed. Laxity Inversion Duration at clip T is the continuance that the current running undertaking can go on running with no loss in schedulability even if there exist a undertaking ( or undertakings ) whose laxness is smaller than the current running undertaking. Hence, MLLF scheduling algorithm avoids the debasement of systems public presentation.Chapter 3Problem FormulationSince the application sphere of this thesis is embedded systems, this chapter starts in subdivision 3.1 with a treatment on the bing programming algorithms based on Real clip systems. Section 3.2 presents the demand of Least Slack First Scheduling Algorithm in stochastic wcet.3.1 Scheduling Algorithms in Real-time SystemsFor a given set of occupations, the general programming jobs asks for an order harmonizing to which the occupations are to be executed by fulfilling with assorted restraints. Typically, a occupation is characterised by its executing clip, ready clip, deadline, and resource demands. The executing of a occupation may or may non be interrupted over a set of occupations and there is a precedency relation which constraints the order of the executing, particularly with the executing of a occupation can non get down until the executing of all its predecessors is completed.Types of Real-Time SchedulingFor illustration the systems on which the occupations are to be executed is characterised by the sum of resources available [ 22, 59, 30, 32, 27, 12 ] . The undermentioned ends should be considered in scheduling a real-time system: [ 30, 32, 27 ] . * Meeting the timing restraints of the system * Preventing coincident entree to shred resources and devices. * Achieving a high grade of use while fulfilling the timing restraints of the system. * Reducing the cost of context switches caused by pre-emption. * Reducing the communicating cost in real-time distributed systems. In add-on, the undermentioned points are desired in advanced real-time systems: * Sing a combination of difficult, and soft existent clip system activities, which implies the possibility of using dynamic programming policies that respect to the optimality standards. * Task programming of using dynamic programming policies that respect the optimality standards. * Covering dependability, security, and safety. Basically, the programming job is to find a agenda for the executing of the occupations so that they are all completed before the overall deadline [ 22, 59, 30, 32, 27, 12 ] . Given a real-time system, the appropriate programming attack should be designed based on the belongingss of the system and the undertakings happening in it. These belongingss are as follows [ 22, 59, 30, 32 ] : _ Soft/Hard/Firm real-time undertakings The real-time undertakings are classified as difficult, soft and steadfast real-time undertakings. Periodic/Aperiodic/Sporadic undertakings Periodic undertakings are real-time undertakings which are activated ( released ) on a regular basis at fixed rates ( periods ) . Normally, periodic undertakings have a restraint which indicates that cases of them must put to death one time per period. Aperiodic undertakings are real-time undertakings which are activated irregularly at some unknown and perchance boundless rate. The clip restraint is normally a deadline. Sporadic undertakings are real-time undertakings which are activated irregularly with some known bounded rate. The delimited rate is characterized by a minimal inter-arrival period, that is, a minimal interval of clip between two consecutive activations. The clip restraint is normally a deadline. An nonperiodic undertaking has a deadline by which it must get down or complete, or it may hold a restraint on both start and finish times. In the instance of a periodic undertaking, a period means one time per period or precisely units apart. A bulk of centripetal processing is periodic in nature. For illustration, a radio detection and ranging that tracks flights produces informations at a fixed rate [ 32, 29, 27, 12 ] . _ Preemptive/Non-preemptive undertakings In some real-time programming algorithms, a undertaking can be preempted if another undertaking of higher precedence becomes ready. In contrast, the executing of a non-preemptive undertaking should be completed without break, once it is started [ 32, 30, 27, 12 ] ._ Multiprocessor/Single processor systems The figure of the available processors is one of the chief factors in make up one's minding how to Agenda a real-time system. In multiprocessor real-time systems, the scheduling algorithms should forestall coincident entree to shared resources and devices. Additionally, the best scheme to cut down the communicating cost should be provided [ 32, 27 ] . Fixed/Dynamic precedence undertakings In precedence driven programming, a precedence is assigned to each undertaking. Delegating the precedences can be done statically or dynamically while the system is running [ 22, 59, 30, 32, 12 ] . _Flexible/Static systems For scheduling a real-time system, we need to hold adequate information, such as deadline, minimal hold, maximal hold, run-time, and worst instance executing clip of each undertaking. A bulk of systems assume that much of this information is available a priori and, hence, are based on inactive design. However, some of the real-time systems are designed to be dynamic and flexible [ 22, 59, 30, 32, 12 ] . _ Independent/Dependent undertakings Given a real-time system, a undertaking that is traveling to get down executing may necessitate to have the information provided by another undertaking of the system. Therefore, executing of a undertaking should be started after completing the executing of the other undertaking. This is the construct of dependence.3.2 Implementing Least Slack First in stochastic behaviour:The laxness of a procedure is defined as the deadline subtraction staying calculation clip. In other words, the laxness of a occupation is the maximum sum of clip that the occupation can wait and still run into its deadline. The algorithm gives the highest precedence to the active occupation with the smallest laxness. Then the occupation with the highest precedence is executed. While a procedure is put to deathing, it can be preempted by another whose laxness has decreased to below that of the running procedure. A job arises with this strategy when two procedures have similar laxnesss. One procedure will run for a short piece and so acquire preempted by the other and frailty versa. Thus, many context switches occur in the life-time of the procedures. The least laxness foremost algorithm is an optimum programming algorithm for systems with periodic real-time undertakings. If each clip a new ready undertaking arrives ; it is inserted into a waiting line of ready undertakings, sorted by their laxnesss. In this instance, the worst instance clip complexness of the LLF algorithm is where the entire figure of the petitions in each hyper-period of periodic undertakings in the system and is the figure of nonperiodic undertakings. vitamin E The executing clip of a undertaking depends on application dependant, platform dependant, and environment dependent factors. The sum of input informations to be processed in each undertaking instantiation every bit good as its type ( pattern, constellation ) are application dependent factors. The type of treating unit that executes a undertaking is a platform dependent factor act uponing the undertaking executing clip. If the clip needed for communicating with the environment is to be considered as a portion of the executing clip, so web burden is an illustration of an environmental factor act uponing the undertaking executing clip.Execution clip chance denseness mapshows the executing clip probability denseness of such a undertaking. An attack based on a worst instance executing clip theoretical account would implement the undertaking on an expensive system which guarantees the imposed deadline for the worst instance state of affairs. This state of affairs nevertheless will happen w ith a really little chance. If the nature of the system is such that a certain per centum of deadline girls is low-cost, a cheaper system, which still fulfills the imposed quality of service, can be designed. For illustration, such a cheaper a system would be one that would vouch the deadlines if the executing clip of the undertaking did non transcend a clip minute t. It can be seen from the, that there is a low chance that the undertaking executing clip exceeds Ts and hence, losing a deadline is a rare event taking to an acceptable service quality.Chapter 4Design and ExecutionThis chapter presents the design and execution of stochastic wcet and LSF scheduling algorithm in subdivision 4.1 severally.4.1 Design of Least Slack First Algorithm:Difficult real-time programming can be thought of as an issue for embedded systems where the sum of clip to finish each explosion is capable to these parametric quantities: Sum of work ( W ) , sum of slack clip ( S ) Assume that the Numberss are specified in footings of processor ticks ( timer interrupts ) . The deadline ( D ) is the amount of W + S, i.e. , slack clip exactly represents the sum of clip which in which the procedure can be preempted while finishing its explosion in order to accomplish the deadline. When a figure of procedures are trying to accomplish their deadlines the undermentioned calculation takes topographic point at each tick ( 1 ) : — W ; // for the current running procedure — Second ; // for all procedures on the ready waiting line Namely, the running procedure has completed another tick of work towards its deadline and the others have one less tick of slack clip available. In scheduling algorithms we imagine for such a system would non be time-sharing, but would be priority-based, where the precedence is measured by some sense of urgency towards finishing the deadlines. Least Slack First ( LSF ) : when a procedure completes a explosion or a new one becomes ready, schedule the procedure whose value S is the smallest. Or, it can concentrate on completing of the overall deadline. Both represent sensible impressions of fulfilling procedure urgency. Here is a simple illustration which illustrates the differing behaviour: Process idle clip explosion — — — – — — — — – — — – A 0 ( W=10, S=8 ) B 3 ( W=3, S=11 ) C 5 ( W=3, S=6 ) Using the LSF algorithm, we would finish these explosions as follows: Time run ready — — — – — — – 0 A ( 10,8 ) ( ) 3 A ( 7,8 ) ( B ( 3,11 ) ) 5 C ( 3,6 ) ( A ( 5,8 ) , B ( 3,9 ) ) 8 A ( 5,5 ) ( B ( 3,6 ) ) 13 B ( 3,1 ) ( ) 16 — – Based on the above illustration the codification has been generated and account for the above illustration: Iteration 1: At clip 0 A will be ( 10, 8 ) Where as 10 is W ( current running procedure ) , 8 is S ( ready waiting line ) . Iteration 2: At clip 3 We have 2 phases: 1. Run phase: At this phase the procedure A will ( 7, 8 ) because For 7: W – idle clip 8: ready waiting line 2. Ready phase: At this phase the procedure B will ( 3, 11 ) because For 3: idle clip 11: ready waiting line Iteration 3: At clip 5 Same as like Iteration 2 here besides we have 2 phases 1. Run phase: At this phase the procedure C will ( 3, 6 ) because For 3: idle clip 6: ready waiting line 2. Ready phase: Procedure A will be ( 5, 8 ) and B will be ( 3, 9 ) For 5: 10-5 i.e. W – idle clip 8: ready waiting line For B: 3: idle clip 9: W+S+idletime – idle clip – idle clip Iteration 4: At clip 8 In Run phase A will be ( 5, 5 ) Because one rhythm is executed so A ready waiting line will be minimized by 3 In Run phase B will be ( 3, 6 ) 6: W-idle clip -idle clip There will be a context switches. Iteration 5: At clip 13 In tally phase B ( 3, 1 ) 1: ready waiting line of loop 3 -idle clip.4.1.1Comparing of Slack undertakings:To compare loose undertakings in LSF with different conditions the codification has been written. if ( slackLeftT1 & lt ; slackLeftT2 ) { return -1 ; } if ( slackLeftT2==slackLeftT1 ) { return 0 ; } if ( slackLeftT2 & lt ; slackLeftT1 ) { return 1 ; } return 0 ; } }4.1.2Implementation of Execution times:In an existent executing clip, the executing block consumes a â€Å" guessed † executing clip that the scheduler is utilizing in its programming determinations. In the map executing, the category Computation demand to utilize the existent executing. In the LSF comparator we must do certain the â€Å" guessed † executing clip is being used. Lashkar-e-taibas denote the existent executing clip as C_to_be_executed_time and it is a data member of the category Computation. this.C_to_be_executed_time = distr.sample ( ) ; // clip that will be consumed by the executing block Let ‘s denote the â€Å" guessed † executing clip as C and it is besides a data member of the category Computation. this.C = distr.sample ( ) ; // Assumed WCET to be used by LSF scheduler We must now guarantee that the execute method consumes C_to_be_executed_time clip units and the LSF comparator uses C. Further, guaranting the executing times that are assigned in the builder of Computation category prevarication in the scope of 0 and some positive upper edge.4.1.3Implementation for scheduling periodic undertakings and work load:The below codification reference to implements the periodic undertakings. Periodic p1 = new Periodic ( 0,31, 0, â€Å" T1 † ) ; p1.installConditionedComputation ( new Computation ( new Normal ( 10,5 ) , p1 ) ) ; The work load can be calculated by, Workload = max executing time/ period clip.Chapter 5Evaluation of SimulationThis chapter describes the public presentation rating of the simulator. Section 5.1 presents the simulator foundation, while in subdivision 5.25.1 Eclipse and the Eclipse FoundationEclipse is an unfastened beginning community ; undertakings are focused on constructing an unfastened development platform comprised of extensile models, tools and runtimes for edifice, deploying and pull offing package across the lifecycle. The Eclipse Foundation is a not-for-profit, member supported corporation that hosts the Eclipse undertakings and helps cultivate both an unfastened beginning community and an ecosystem of complementary merchandises and services. The Eclipse Project was originally created by IBM in November 2001 and supported by a pool of package sellers. The Eclipse Foundation was created in January 2004 as an independent not-for-profit corporation to move as the steward of the Eclipse community. The independent not-for-profit corporation was created to let a seller impersonal and unfastened, crystalline community to be established around Eclipse. Today, the Eclipse community consists of persons and organisations from a cross subdivision of the package industry. In general, the Eclipse Foundation provides four services to the Eclipse community: 1 ) IT Infrastructure. 2 ) IP Management. 3 ) Development Process and, 4 ) Ecosystem Development. Full-time staffs are associated with each of these countries and work with the greater Eclipse community to help in run intoing the demands of the stakeholders. Eclipse – an unfastened development platform Eclipse is an unfastened beginning community ; undertakings are focused on constructing an unfastened development platform comprised of extensile models, tools and runtimes for edifice, deploying and pull offing package across the lifecycle. A big and vivacious ecosystem of major engineering sellers, advanced start-ups, universities, research establishments and persons extend, complement and back up the Eclipse platform. Used for 1. Enterprise Development. 2. Mobile + Device development. 3. Application model, linguistic communication ide. Eclipse Undertakings Eclipse is a aggregation of unfastened beginning undertakings built on the Equinox OSGi run-time. Eclipse started as a Java IDE, but has since grown to be much, much more. Eclipse undertakings now cover inactive and dynamic linguistic communications ; thick-client, thin-client, and server-side models ; patterning and concern coverage ; embedded and nomadic systems.5.2 simulator apparatus:On a high degree, the simulator simulates a computing machine system by utilizing objects that encapsulate different functionality and make up one's mind on parametric quantities on the objects. The undermentioned categories are of import: 1.ComputerSystem: c.add ( central processing unit ) ; 2.CPU: A CPU that is bound to the computing machine system DataDependencyGraph g = new DataDependencyGraph ( ) ;g.insertData ( 1, 0, 0 ) ;g.insertData ( 2, 0, 0 ) ;g.insertData ( 3, 0, 0 ) ;A information dependence graph that describes informations points in the system and their relationship. Think of the relationships a borders between nodes in a directed acyclic graph. Constructs a information dependence graph of three informations points. These informations points have no relationships. 3. ConditionedExecution: At least one learned executing that is bound to a undertaking. Periodic p1 = new Periodic ( 0, 100, 0, â€Å" T1 † ) ;p1.installConditionedComputation ( new IfTime ( 1, 10, 1, p1, g ) ) ;p1.installConditionedComputation ( new Computation ( 10, p1 ) ) ; Periodic p2 = new Periodic ( 0, 200, 0, â€Å" T2 † ) ;p2.installConditionedComputation ( new IfTime ( 1, 10, 1, p2, g ) ) ;p2.installConditionedComputation ( new Computation ( 10, p2 ) ) ; Periodic p3 = new Periodic ( 0, 103, 0, â€Å" T3 † ) ;p3.installConditionedComputation ( new IfTime ( 2, 10, 1, p3, g ) ) ;p3.installConditionedComputation ( new Computation ( 10, p3 ) ) ;Concepts three periodic undertakings. Each undertaking has two conditioned executings that execute in the order they are bound to the undertaking. 4.Tasks: At least one undertaking that is bound to a CPU. Vector & lt ; CPU & gt ; c = new Vector & lt ; CPU & gt ; ( ) ;CPU central processing unit = new CPU ( new WinOverSlack ( ) ) ;cpu.installTask ( p1 ) ;cpu.installTask ( p2 ) ;cpu.installTask ( p3 ) ;Instantiates a CPU and bounds the undertakings to the CPU. 5.Events: At least one information point that may be used by an executing ComputerSystem cs = new ComputerSystem ( degree Celsius, hint ) ;cs.eventLoop ( 10000 ) ;Concepts a computing machine system and bounds the array of CPUs to it. The method eventLoop starts the simulation and the simulation coatings when it reaches clip point 10000. 6.Trace: Trace hint = new Trace ( new OutputStreamWriter ( System.out ) ) ;Instantiates a hint where the end product of the simulation will be written. This hint writes to standard end product, which makes the end product to look in the console in Eclipse. In simulation, I used stochastic executing times on a sort of learned executing that is bound to a undertaking. This means that every clip the learned executingexecutes it consumes different sums of clip. Therefore, when an case of a undertaking starts we can take a conjecture how much clip it will devour. The system uses LSF that use the guessed executing clip.End product:Chapter 6This chapter focuses on alternate attacks and related research works viz. stochastic undertaking executing times. Hence, in the below subdivision we discussed related plants on stochastic worst instance executing times.Related plantsSome of the related work in stochastic undertaking executing times: Burns et Al. : [ BPSW99 ] addresses the job of a system by interrupting its seasonableness demands due to transeunt mistakes. In this instance, the executing clip variableness stems from undertaking re-executions and the shortest interval between two mistake happening such that no undertaking exceeds its deadline and is determined by sensitiveness analysis. The chance that the system exceeds its deadline is given by the chance that faults occurs at a faster rate than the tolerated one. Broster et Al. : [ BBRN02 ] Determines the response clip of a undertaking ; it re-executes K  º N times due to mistakes in order to obtain the chance distribution of the response clip, and it compute the chance of the event that K mistakes occur. The mistake happening procedure is assumed to be a poisson procedure in both of the cited plants. But Burns et Al. : Extend broster ‘s attack by adding statistical dependences among executing times. His attack are applicable to systems with sporadic undertakings, which are unsuited for the finding of undertaking deadline miss chances of undertakings with generalised executing clip chance distributions, and besides confined to sets which are independent undertakings implemented by utilizing monoprocessor systems. Bernat et Al. : [ BCP02 ] Address different job which determines the frequence with which a individual undertaking executes for a peculiar sum of clip, called executing clip profile and this was performed by based on the executing clip profiles of the basic blocks of the undertaking. The strength of this attack is that they consider statistical dependences among the executing clip profiles of the basic blocks. But nevertheless, this attack would be hard to widen to the deadline miss ratio analysis of multi-task systems because of the complex interleaving with the features of undertaking executings in such environments. Atlas and Bestavros: [ AB98 ] extends the classical rate monotone programming policy with an entree accountant in order to manage undertakings with stochastic executing times. It analyses the quality of the service of the ensuing agenda and its dependance on the entree control parametric quantities. The attack is limited to monoprocessor systems, rate monotone analysis and assumes the presence of an admittance accountant at run-time. Abeni and Buttazzo ‘s [ AB99 ] work addresses both programming and public presentation analysis of undertakings with stochastic parametric quantities. It focuses on how to schedule both difficult and soft real-time undertakings on the same processor, in such a manner that the difficult 1s are non disturbed by ill-behaved soft undertakings. Tia et Al. [ TDS95 ] presume a undertaking theoretical account composed of independent undertakings. There are two methods for public presentation analysis they were, one of them is merely an estimation and is demonstrated to be excessively optimistic. In the 2nd method, a soft undertaking is transformed into a deterministic undertaking and a sporadic 1. The sporadic undertakings are handled by a waiter policy. The analysis is carried out on this peculiar theoretical account. Gardner et Al, [ GAR99, GL99 ] in their stochastic clip demand analysis, present worst-case scenarios with regard to task release times in order to calculate a lower edge for the chance that occupation meets its deadline. It does n't incorporate informations dependences among undertakings and applications implemented on multiprocessors. Zhou et Al. and Hu et Al. [ ZHS99, HZS01 ] root their work in Tia's. , they do non mean to give per-task warrants, but characterize the fittingness of the full undertaking set. Because they consider all possible combinations of executing times of all petitions up to a clip minute, the analysis can be applied merely to little undertaking sets due to complexness grounds. De Verciana et Al. [ BPSW99 ] address a different type of job. Having a undertaking graph and an imposed deadline, its end is to find the way that has the highest chance to go against the deadline. In this instance, the job is reduced to a non-linear optimisation job by utilizing an estimate of the whirl of the chance densenesss. Diaz et Al. [ DJG00 ] derives the expected deadline miss ratio from the chance distribution map of the response clip of a undertaking. The response clip is computed based on the system-level backlog at the beginning of each hyper period, i.e. the residuary executing times of the occupations at those clip minutes. The stochastic procedure of the system-level backlog is Morkovian and its stationary solution can be computed. It contains sets of independent undertakings and the undertaking executing times may presume values merely over distinct sets. In this attack, complexness is mastered by paring the passage chance matrix of the implicit in Markov concatenation or by deploying iterative methods, both at the disbursal of consequence truth. Kalavade and Moghe [ KM98 ] see undertaking graphs where the undertaking executing times are randomly distributed over distinct sets. Their analysis is based on Markovian stochastic procedures excessively. Each province in the procedure is characterized by the executed clip and lead-time. The analysis is performed by work outing a system of additive equations. Because the executing clip is allowed to take merely a finite ( most probably little ) figure of values, such a set of equations is little. Kim and shin [ KS96 ] see applications that are implemented on multiprocessors and modeled them as line uping webs. It restricts the undertaking executing times to exponentially distributed 1s, which reduces the complexness of the analysis. The undertakings were considered to be scheduled harmonizing to a peculiar policy, viz. first-come-first-served ( FCFS ) .Chapter 7Conclusion & A ; Future worksThis chapter gives decisions in subdivision 7.1 and discusses issues for the future work in subdivision 7.27.1 DrumheadNow a yearss, systems controlled by embedded computing machines become indispensable in our lives and can be found in batch of application. And the country of embedded real-time systems introduces the facets of stochastic behavior of real-time systems. In my thesis I deal with platform specific stochastic undertaking. Because of rapid growing in embedded systems by twenty-four hours to twenty-four hours, the undertakings in a system are incomplexed mode in a existent clip system and it is normally assumed that the undertaking consume wcet in every supplication. And it is pessimistic premise that is made in order to vouch difficult real-time public presentation. But we have besides soft real-time restraints so that pessimistic premise could be relaxed. In my thesis I worked on loosen uping the pessimistic premise so that more systems are schedulable and more over it is really of import for a system to work on a higher work burden where it is to be schedulable. By this I can do this system to lose their deadlines.7.2 Future workBased on my thesis work, In certain countries it can be better farther by implementing Modified Least Laxity Scheduling Algorithm. By, the aid of this algorithm we can understate the context switches. By understating it, we can non happen any deadline girls and there will be hundred percent use of system which contains higher work burden.Chapter 8Mentions[ 1 ] hypertext transfer protocol: //www.cs.wcupa.edu/~rkline/OS/Scheduling-examples.html, Last updated: Oct 17, 2007.

The timing diagram of undertaking t1 before scheduling The timing diagram of undertaking t2 before scheduling The timing diagram of undertaking t3 before scheduling Sing a system dwelling of three undertakings and that have the repeat periods, calculation times, first supplication times and deadlines are defined in above tabular array. The undertakings are pre-emptive.Earliest Deadline First AlgorithmAs presented in below, the uniprocessor real-time system dwelling of the undertakings Set defined in Table 3 is non EDF-schedulable, because while the executing of the first supplication of the undertaking t2 is non finished yet ; the new supplication of the undertaking arrives. In other words, an overrun status happens. _ ?Rate Monotonic AlgorithmAs shown in below, the uniprocessor real-time system dwelling of the undertakings set defined in above tabular array is non RM-schedulable. The ground is that the deadline of the first supplication of the undertaking t3 is missed. The executing of the first supplication is required to be finished by clip 6, but the agenda could non do it.Least Laxity First AlgorithmBelow nowadayss a part of the timing diagram of the agenda provided by the least laxness foremost algorithm on the undertakings set defined in above tabular array. As shown in the, the deadline of the 3rd supplication of the undertaking t1 can non be met. we conclude that the uniprocessor real-time system dwelling of the undertakings set defined in tabular array is non LLFschedulable.

The Meaning of Leaf Names in Latin or Greek

The Meaning of Leaf Names in Latin or Greek The following words are used in plant names to describe the leaves or foliage of plants. The basic Latin word for leaf is folium. Since folium is a neuter noun, the plural ends in a (folia). Botanically, folius is used as an adjective, as well. Foliatus, the masculine adjectival form of the Latin word for leaf, means leaved. The feminine adjectival form is foliata and the neuter is foliatum. If youre interested in picking up Latin vocabulary, strip the folius word from each entry on the following list. Example: In the case of acuminatifolius, stripping out folius leaves acuminat- plus a connecting vowel i. Acuminat- is from the past participle of acumino, -are, -avi, -atus which translates into English as to sharpen or to make sharp. Acuminat- may be familiar to you from the English word acumen.

Gang Violence in America essays

Gang Violence in America essays Gang violence presents one of the most significant crime problems in the United States. It is however hardly a recent problem. Indeed, according to Johnson Globalization is noted as one of the culprits in the success of gang activity in the United States (Johnson s online information systems make it easy to obtain information regarding gangs, their members, and their activities. Solutions offered for the gang problem range from governmental interventions to family education. Domestic anti-gang policies are for example suggested, along with migration reforms. Time and space for gang-related activities limited by offering alternative school and youth programs, is another suggestion. The government should also more clearly coordinate its activities with its neighbors such as Mexico and Central America; with the understanding that these connections worsen the condition in the United States. Other suggestions relate to the family and school environment. In the family context, for example, it is noted that...

Editing - Essay Example The ANWR oil drilling issue has even reached the point that it has become an agenda for national elections. Both the Republicans and the Democrats have used their respective stand on this subject as part of their strategies in gathering political support for every electoral contest in which they participate. The Democrats have held the stand of opposing oil drilling in the area since President Clinton (Douglas). On the other hand, the Republicans have been pushing for the opening of the 1002 Area for exploration and eventual extraction. However, the political noise generated by the debate on this issue between the Republicans and the Democrats has only blurred further the merits and demerits of oil drilling in the ANWR. Therefore, people are led to choose which political party line they should follow instead of basing their stand on the issue on the concrete evidence and logic. If provided an objective view on the issue, however, minus the

Common ground Essay Example | Topics and Well Written Essays - 1000 words

Common ground - Essay Example According to Terris (1999), one sixth of the total land base in our country yielded to development within a short ten year period from 1982 to 1992. This author’s article deals with the issue of a decline or extinction in various species caused by bulldozing down grasslands and forests, thus building towards a plea for the conservation and preservation of wildlife. The article by Shaw (2004) however, does acknowledge that human activity has stripped away a considerable amount of forested land, thereby depriving the wildlife of their habitat; however reforestation has also been active and this has produced a condition where the nation is now a haven for wild animals and many species that were once endangered are not multiplying in record numbers. For wxample, Shaw (2004) cites the example of the bald eagle, whose population was once down to 32 pairs but has now increased to 329 known active bald eagle nests. In providing an argument that urban sprawl has contributed to the decl ine in certain species of wildlife, Terris(1999) provides specific examples of such species that have been out at risk, such as the Florida panther, the pygmy owl, the kangaroo rat and even plant species such as the saguaro cactus. Her analysis is based upon the following main arguments: (a) Development of land for habitation and especially leap frog developments have eroded the natural habitat for wildlife. (b) Patterns of urban growth have produced loss of habitat for several species of wildlife, fragmentation or the breakup of ecosystems and the generalization of ecosystems wherein only the hardy species that can survive on green lawns and stuff from garbage cans are able to survive. (c) Conservation alone cannot save wildlife, what is necessary is control over development patterns, i.e, restricting unfettered and unplanned development and effectively managing growth in such a manner that it protects wildlife The article by Shaw (2004) is based upon two singular aspects; first th e proliferation of wildlife and second, the increasing proximity of humans to wildlife. In support of her claim that reforestation is rekindling many once diminished species, Shaw (2004) offers the following arguments: (a) Natural reforestation is increasing due to the decline in farming, especially in the eastern United States, which is also increasing wildlife (b) Suburbanization or low density development outside the cities provides a variety of habitat and vegetation that is a draw for animals. (c) A new ecology is being established, i.e, with suburbanization, people build new kinds of habitat such as bird feeders, gardens and ornamental nurseries which are breeding grounds for meso mammals, or mid sized species which only need smaller areas to roam (d) Some species such as deer and geese are both wildlife success stories and a cause of nuisance as well. For example, deer can be a nuisance in the form of deer related collisions, carriers of Lyme disease and damage to crops and s eeds. (e) Increasing proximity of wildlife has become a cause of concern in several areas, for example a mountain lion attacked a woman riding a bicycle near a wild life park. (f) On the basis of her arguments, Shaw(2004) argues that there seems to be an apparent compatibility between human and wild life and the growing notion and people can exist side by side with wilds animals. Entrepreneurs are making efforts to build natural sites

Supply chain management in new zealand Essay Example | Topics and Well Written Essays - 500 words

Supply chain management in new zealand - Essay Example This fundamental approach particularly in the food management in New Zealand is characterized by the integration of research in the actual Supply Chain Management. This is evident how the consumers have become integral parts of climate or consumer survey in order to ensure awareness of their increasing demand. Not only that. The systematic trainings and programs given to producers in line with food safety solutions and biosecurity solutions are moves that are paving the way for sustainability. In other words, the current state of supply chain management in New Zealand with the aid of individual entities like AgriChain Centre is helping the nation towards the achievement of sustainability that could integrate safety and quality in food production. It is clear that sustainability in food production is the bottom line of this, which further takes New Zealand to unite the concept of supply chain management in a most efficient and systematic manner. The significant proof concerning this claim, as already stated, is visible from how research has become fundamental component in the entire process of obtaining sustainability in the food production. Supply chain management is a broad area of concern, but one important point in doing this is to ensure that the external relationships between the players in the entire supply chain are in good shape and under control for optimum achievement of target goals and objectives. In fact, the processes across the supply chain and the development of supply chain relationships are characteristics of supply chain management (Jespersen & Larsen, 2005, p.14). All of these characteristics are able to take place in New Zealand if we based it on how AgriChain Centre involves itself into the actual agricultural production in participation with private and public sectors and the consumers. In this process, there

Self-Sacrifice and the Leadership Effectiveness Essay

Self-Sacrifice and the Leadership Effectiveness - Essay Example Further, self-sacrifice can help groups particularly faced with crisis and the reciprocity norm asserts that individuals are under pressure to assist those who have assisted them. Clearly, this norm may function as a behavioral rule that is present in the continuing relationships, and that makes them be stable. Additionally, self-sacrifice may function as an intrinsic motive that leads to satisfaction and that makes individuals reciprocate. A self-sacrificing behavior by the leader creates pressure on the followers to act as is required of them. Particularly, to forgo self-interest and committing oneself to the good of the collective is what is required of self-sacrifice (Knippenberg & Knippenberg, 2005, p. 25).Nelson Mandela is an ideal example of a leader who intensively and extensively struggled for the sake of South Africa freedom. Mandela sacrificed a lot to the South African movement for freedom, including his private life and liberty. His ultimate goal was to ensure his fellow Africans have gained the much-needed freedom in their country. Commenting on his desire to sacrifice to attain freedom, Mandela maintained that freedom cannot be easily acquired anywhere in the world. In addition, most individuals would have to go through a valley of the shadow of death always until we get to the top of our aspirations (Limb, 2008). He stated during his Heritage Day address on 24 September 1997 that, â€Å"Let us recommit ourselves to the ideals in our Constitution, ideals which were shaped in the struggles†.

Political Action Awareness Research Paper Example | Topics and Well Written Essays - 500 words

Political Action Awareness - Research Paper Example tempts, the basic philosophy of health has not changed, and these measures have been viewed as an inside erosion of the core principles of caring that attracted many professionals to health care initially. Given the values of policy-makers and senior managers of the quasi-market, health care workers found that their practices were molded into a culture that presented them with legislative and ethical challenges. Ethical issues such as promotion of narrow policies, inadequate qualified staff to provide health care and the obligation to follow poorly outlined strategies (Finkelman & Kenner, 2013, 245). Therefore, it is the health professionals’ responses to these issues that will set the scene and write the script for better services in the health care sector of the economy. Despite the presence of collaboration in the various health disciplines, and the shift of balance of power from a medical supremacy to a mutual viewpoint, none of the professionals involved in health care have ownership in the care service they offer. Public health services are owned by funding from the government, and thus professionals involved in the service have no effective voice. Political and professional courage is a necessity amongst managers and nursing leaders so as to steer nursing towards eradicating people’s dualism to individual against collective health and improve social health services. Activist nurses, with an informed vision, can play a significant role in improving the level of discourse in the society. Managers or leading nurses need to outline the conditions for work so that nurses have the responsibility and rights to act as political individuals in national and local arenas. Nurses ought to have a system that moves from being away from people’s daily experience to one that offers resources to policy-makers and the community. For excellent policy making to occur, leading nurses as interpreters and advocates of science must feel sanctioned to support their health

HUNTING THE NIGHTMARE BACTERIA Essay Example | Topics and Well Written Essays - 500 words

HUNTING THE NIGHTMARE BACTERIA - Essay Example Bacterial infections long before the discovery of penicillin used to result in deaths from simple infected wounds. As times progressed, scientific intervention relieved people from the fatality of sepsis. However resistant genes and bacteria seem to have brought back such infections. In the case of Addie Rerecich, a MRSA infection from a single scrape wound resulted, which aggravated upon further treatment and multiplied due to medical intervention, exacerbating her debility to the point where doctors deemed it untreatable, yet bought her some time with surgical intervention. Similarly David Ricci introduced NMD-1 into the United States, leaving doctors who had never treated a patient for such a bacteria; no choice but to quarantine him. Likewise, the alarming outbreak of KPC in New York threatened patient admission in the NIH, leaving the doctors baffled with the inability to control the spread of such a bacteria. The resistance of bacteria to antibiotics has thus posed problems for the doctors, pharmacists, microbiologists and researchers time after time due to the fact that medical resources are finite and the invading organisms are gaining strength in their pathogenicity. As a result, medicines no longer prevent their spread as efficiently as they used to. There are many possible reasons that may have fueled the growth of resistant bacteria beyond the control of health specialists. Firstly, the antibiotics are often prescribed for ailments that do not require them, which results in bacteria becoming resistant to a specific class of anti-microbial drugs. Secondly, it is due to the silent spread of these bacteria across individuals who often do not exhibit symptoms unless it is too late and the bacteria have spread. Unlike humans, the bacteria can transmit mutated genes across contaminated water and grow resistant to antibiotic medication even before they have entered their hosts. Moreover, it may also result

Running Fence by Christo and Jeanne-Claude Essay

Running Fence by Christo and Jeanne-Claude - Essay Example The biggest continuous part of the Running Fence that remains intact is hanging below Rio Theater’s ceiling in Monte Rio. The Running Fence is perceived to be among the most significant projects as far as public arts are concerned, and at the time when it was installed, it was one of the most ambitious projects that were embarked on by Christo and Jeanne-Claude after they arrived in the US in 1964. When the art piece was made public at America’s bicentennial, it caught the imagination of the public as the exceptional beauty of the light as well as the weather that played across the fence’s fabric sharply contrasted with the issue of limitations and division that underlie the aspects that are usually conveyed by fences. In the case of Christo and Jeanne-Claude, the fence was an embodiment of bigger issues in regards to human freedom as well as a constraint. The manner in which the Running Fence was planned, designed and installed along with the critical response t o the piece was a tone-setter for the rest of their bigger projects as none of them could have been conceivable without the Running Fence. Between 1972, when the idea of the Running Fence was initially conceived and 1976 the artists experienced apparent overwhelming difficulties and apart from negotiations of land rights with numerous ranchers, they had to deal with administrative obstacles at a time when they were not famous. The two artists had the ability to convince ordinary people of the transformative aspects associated with art.

Use of Films for ESOL Learners

Use of Films for ESOL Learners CHAPTER I INTRODUCTION This chapter presents background of the study, statement of the problem, purpose of the study, significance of the study, scope and limitation of the research, and definition of key terms. Background of The Study Writing is a complicated skill, writing is a skill that the language teacher must teach to their students. And also it is very important because writing van give the student chance to show or express their personalities, and to mastery and to develop the English ability (Scot and Ytreberg,1992). In addition, because of writing, the learners learn to communicate with other people in order they will understand each other, or to read the message and they need to write it. (Raimes, 1983). That its why writing will give benefit for students if they mastered this writing. Writing is not skill where the students get easily and naturaly. It means, English as Foreign Language learners are not taught how to write a good narrative story in English language. However, to teach writing not only about grammar, the mechanics of the alphabet or the spelling, but also the learners need to see the ideas or concepts in English language. Lack of vocabulary is also the problem when the teacher ask students to write. The students look confused and asking their friend about what is the English language for some words. High school students are asked to write simple and short sentences, messages, short announcements, and also to write narrative, and other type of paragraphs (Depdiknas, 2006). In the statement above, the teaching of writing at high school is a simple one. However, writing is productive skills besides speaking, but still look complicated skill for SMA students to master. It is a complex activity that need a variety of skills. Due to that condition, the researcher tries to find out a kind of technique that can help students write sentences or a simple paragraph and encourage them in the writing activity. The researcher assumes that one of the good ways of teaching writing is by using media. Instructional media is important in teaching and learning processes in order the students can enhance and promote learning and support the teacher’s instruction. The use of media needs to be planned carefully. There are so many kinds of media that can be used in the teaching writing process. One of them is short movie. Short movie can be the basis of the most difficult side: motivate students to write. Short movie as the media are very useful for teaching English writing, especially to attract and giving the anxiety to the students’ attention and to deliver the information. So, in teaching writing, the teacher can use short movie to motivate the students to write, to help, to stimulate and to guide students to write a narrative paragraph. In this research, the researcher tries to implement the using of movie strategy into the teaching of narrative paragraph. A narrative paragraph is a paragraph that retells events happening in the past. It focuses on individual participants, uses correct grammar: past tense, focuses on a sequence of events, and it uses action clauses. To make a good narrative paragraph, it would be better if the teachers use short movie to make the learning process clear and make students understand, and the students will arrange the sentences in a good chronological order. The researcher believes that picture series is applicable for the students in SMAN I MANYAR GRESIK because it may guide, help, motivate and encourage the students to express and show their ideas, opinions, and thoughts onto paper. 1.2 Statement of The Problem The research problem in this research is in a question form: â€Å"How can 11th grade of SMAN I MANYAR students’ ability in writing narrative paragraphs be improved by using short movie?† 1.3 Purpose of The Study According to the problem above this research is to describe how the 11th grade students ability in writing narrative paragraph at SMAN 1 MANYAR can be improved by using short movie. 1.4 Significance of The Study The findings of this research can be useful for the teacher and other researchers. For the teachers, the finding of this study can give the alternative way or technique in teaching writing narrative texts. 1.5 Scope and Limitation of The Study The research is focused on the teaching and learning process by involving the 11th grade students of SMAN I MANYAR GRESIK in short movie to improve their writing ability in narrative texts. The improvement is focused on four components: organization, vocabulary, grammar, and mechanic. Those components are analyzed using analytic scoring rubric for writing. 1.6 Definition of Key Terms In order to avoid misunderstanding, the researcher defines several important terms in this proposal: Short movie is a movie that has a short duration about 15-20 minutes length. Narrative is a piece of text which tells a story and has generic structure begins from orientation, complications, and resolution. Writing ability is a way that needs skill of communicating a message to a reader to express idea, thoughts and feelings. Improve is make something to be better. From low to high. CHAPTER II REVIEW OF RELATED LITERATURE This chapter aims to provide a review of the literature related to the teaching of English in Indonesia, the problem of writing, the previous research and the media. 2.1 The Teaching of English in Indonesia English is the international language which is used in communication, or an activity every time. Mastering English is getting important. In Indonesia, English is a compulsory subject. But it seems that the teaching of English as a Foreign Language is not to lead the students to be able to communicate, but only to prepare the students to pass the national examination (Kam Wong, 2004:181). But nowadays, many teachers and learners realize if learning English is not only the skill that we need to pass the exams, but also for communication. Saukah (2000) states that the purpose of teaching English as a foreign language in Indonesia is that the learners will master to use English for communication; in written or oral language. The ability to communicate is the way how we are able to understand and show to express something. Writing is one of four language skills which has important role in teaching English as a Foreign Language. Brown (2001), writing is simple as putting the ideas or concepts into paper. Compared to speaking, writing is more difficult because writing has the typical characteristics of language that are more complex than those of spoken language such as the degree of formality. Naturally, the process of writing needs the different set of competencies and skills which not every writer has. As beginners, Senior High School students, of course, cannot be expected to master and apply all those writing skills. The students still have a lot of problems in expressing their ideas in writing form. The curriculum expects students to be able to write simple message and simple paragraph at Junior High School. This expectation has not been achieved yet because the students still find it difficult to express and show their ideas in the written language especially in English. This statement based on fact that most of the students’ paper cannot be understood well because there are so many errors. 2.2 Previous Research Research on using short movie strategy has been conducted by some researchers. Sumarsih (2006) did a study using short movie to teach English at the XI IPA-1 students of SMA Negeri 8 Medan. The study showed that the first score of the students’ test was 42,5 for the total improvement from the first competency test to the third competency test was 68,75%. The conclusion is that the student achievement was improved by using the media such as short movie. So the points that we can conclude from using short movie strategy in teaching writing are (1) stimulates the students to be active in English classes during the activity, (2) activates the four language skills (speaking, listening, readning and writing at the same time), (3) produces a fun English class as the best way to learn English, (4) increase students’ achievement. Media for Teaching Writing Listiyaningsih (2002), to facilitate the teaching and learning process, several kinds of media can be used as useful means of teaching in interesting ways. In fact, teaching and learning activities are communication processes. So, using media in teaching writing are good to encourage and stimulate the students to be actively involved during the teaching and learning processes. The media are: Short Movie Sound speaker Proyektor CHAPTER III RESEARCH METHODOLOGY This chapter contains the description of the research methodology. It includes research design, population and sample, subject and setting, data collection, and data analysis. 3.1 Research Design In this study, the researcher uses Classroom Action Research because the researcher wants to improve the students writing skill. The researcher uses short movie as instructional media to improve the students writing skill. It will be brought by the researcher as a new teaching technique in the class. Particularly, the aim of this study is to find a new strategy or technique in learning English writing which can help the teacher to solve classroom problems. The researcher implemented the CAR by Kemmis and Mac Taggart (1998). There are four phase or steps in this action research: (1) planning an action, (2) implementing an action, (3) observing and (4) reflecting. 3.2 Population and Sample The population of the study consisted of 360 students ; 124 male students and 236 female students in SMAN 1 MANYAR Gresik 11th grade . The sample of this study consisted of 36 students of class XI IPS 2: 16 male students and 20 female students, which chosen by cluster sampling at SMAN 1 MANYAR Gresik 11th grade . 3.2.1 Subject and Setting This research was conducted at SMAN 1 MANYAR Gresik 11th grade.. This school had thirty (30) classes and each level had ten (10) classes. The subjects of this study were class XI IPS 2, at the academic year 2013/2014. The class consists of thirty six (36) students. The reason why the researcher chose this class because this class had the most problems in writing. 3.3 Data Collection 3.3.1 Intrument The instrument of this research; First, document collection was conducted by collecting students’ papers at the end of the steps to be evaluated. The data that researcher test are two data in cycle 1 and cycle 2. Both of the cycle are test which will have different movie that will be showed to the students. And the papers the students submitted not just the result of narrative paragraph, but also all their drafting in order to evaluate their progress when they write before. Second, field notes were used as instruments to know what was happened such as the condition and the setting of the class, the atmosphere of the classroom and the other unexpected things that happened. Third, interviews were conducted in two types; at the beginning of the study in order to gather data about the students’ problems in writing and at the end of to find out the students’ understanding the implementation of the narrative paragraph using short movie strategy. Finally, questionnaires was applied at the end of the cycle to know about the students’ responses and attitude in the implementation of the approach. 3.3.2 The Procedure of Collecting Data The researcher did the steps proposed by Kemmis and Mc Taggart (1998) as illustrated below; The researcher explains the research procedures start from preliminary study and research implementation; including planning, implementation, observation, and reflection which is appropriate with the illustration above. Planning: The teacher plans about the lesson plan, materials, media, the instruments. Implementation: In this part, the teaching and learning processes are carried out by the researcher, helped by a collaborator or teacher to observe the students’ progress during the process of learning. Observation : the process of recording and gathering all of the data during the teaching and learning processes. Reflection: the researcher and the collaborative teacher are discussed the result of the implementation if it is success or not. 3.4 Data Analysis In evaluating the students’ writing scores and results, the researcher uses analytic scoring rubric whose components of writing are scored partly and separately based on the composition such as; content, language use, and mechanic. The researcher wants the students will has minimum target score at least 60. Table 1. Scoring Rubric of Evaluating the Students’Writing Products Components of Writing Level Scale and Descriptor Content: Vocabulary Chronological order 4 The content is relevant to the topic and easy to understand. 3 The content is almost complete, relevant to the topic. 2 The content is relevant to the topic but is not quite easy to understand. 1 The content is not quite relevant to the topic. Language use: Use Past Tense 4 No grammatical inaccuracies 3 Some grammatical inaccuracies 2 Several grammatical inaccuracy 1 Frequent grammatical inaccuracies Mechanics: Spelling Punctuation Capitalization 4 It uses correct spelling, good punctuation, and capitalization 3 It has occasional errors of spelling, mistaken punctuation, and capitalization 2 It has frequent errors of spelling, punctuation, and capitalization 1 It has no mastery of convention – dominated by errors of spelling, punctuation, and capitalization Adapted from J.B. Heaton (1990:111) with some modification. From the scoring rubric of writing narrative in table 1, the maximum score is 12 (3 x 4) and the minimum is 3 (3 x 1). So, to identify the final score of the students’ achievement in writing narrative is based on the following scores category in the table. And the scoring is: Data Display There are four kinds of data that collected in this research and most of them were in the form of qualitative data. They were collected from document collection, field notes, interviews, and questionnaires. 1
