Introduction In 2004, the United Nations published a report (United Nations, 2004) predicting that the world’s population would steadily increase, year on year, until at least 2050. Between 2004 and 2010 the world’s population increased by 5 million people (PRB, 2004 and PRB 2010), demonstrating the validity of this prediction. Last year, the United Nations (United Nations, 2010) published another report estimating that over 900 million people were still suffering from malnourishment, highlighting an insufficiency within the volume and distribution of food currently being produced.   As a consequence, it has recently been suggested that as the population grows the number of people facing food insecurity will also increase (Den Herder et al, 2010), unless the pressures affecting food production can be alleviated. To increase the volume of food being produced, scientists have advised that at least one of the following objectives has to be achieved (Godfray et al, 2010): Improve the quantity and quality of crop harvesting Identify or create more arable land (land that can be used for growing crops) By increasing the quantity of the food we produce we should theoretically be able to feed the growing population. In recent years the use of fertilizers and pesticides have been used to enhance the quality and quantity of the crops however use of this cannot be increased due to the risks to public health (Den Herder et al, 2010), and so other options must be explored. Scientists are investigating methods with which to promote a plant’s intake of nutrients and to increase their tolerance against hostile environmental conditions such as drought. Another area scientists have been exploring is that of how to convert land that would be considered unsuitable for plant growth (Den Herder et al, 2010). By finding more land on which to cultivate crops, we could generate more produce using our existing techniques. There is extensive research being conducted in both of these areas however this project will only be focussing on the work being contributed by the Plant Science Group.   This Group are part of the Institute of Molecular, Cell and Systems Biology within the College of Medical, Veterinary and Life Sciences at the University of Glasgow.   The Plant Science Group consists of over 50 active scientists, of which Dr Anna Amtmann is currently a Research Group Leader, and their work covers a range of topics from plant nutrition to plants effect on human metabolism.   Within the Plant Science Group, Dr Amtmann’s Research Group is conducting research into the plant Arabidopsis Thaliana, with the aim of â€Å"understanding the molecular mechanisms involved within (Amtmann, 2011)†: Nutrient usage efficiency Salt and drought tolerance Interaction between abiotic and biotic stress To achieve this understanding experimental research is being conducted in a number of areas by her team, and this project aims to support the work within Nutrient Sensing and Root System Architecture. This research involves growing Arabidopsis Thaliana in controlled environmental conditions and analyzing the effect on the plants by monitoring their individual root structures. By comparing root system architectures that have developed in different environmental conditions, specific traits can identified which can lead to the understanding of how plants intake different nutrients and respond to specific stresses. Currently, the team grows hundreds of samples Arabidopsis Thaliana and records information about each of their root system architectures. This results in large volumes of data that require analysis and documentation. Currently the team create graphs to visualise and analyse this data but they have recently advised of the unsuitability of this approach.   This is predominantly due to the limited visualization options of graphs when considering root parameters and the fact that graphs can extremely time-consuming to construct. Therefore, this project aims to develop a system that will allow Dr Amtmann’s Research Group to visualise root system architectures of Arabidopsis Thaliana by using techniques that will manipulate the root structure architectural data into interesting and understandable representations. The following chapters of this proposal aim to document the proposed work that will be undertaken in a master project that will achieve this aim. 2. Problem Statement Due to the biological nature of this project, this section will define a number of key concepts required to understand the work undertaken by Dr Amtmann and her colleagues, and the issues they face, before discussing the intentions of this project. Root System Architecture Dr Amtmann’s team assesses the root system architectures of Arabidopsis Thaliana to understand how environmental conditions affect its development. The root system of a plant is responsible for the intake of water and nutrition (Malamy, 2005), among other essential functions, and so plays an important role within the development of any plant.   The root system normally consists of a main root with a number of lateral branches, which contain a number of root hairs that are responsible for the uptake of nutrients and water (Wikipedia, 2011). The way in which these underlying roots expand and branch is considered to be the root system architecture (RSA) (Figure 1). Depending on the environment in which a plant resides, changes occur to the RSA that can have a significant effect on the water or nutrient uptake of the plant(Armengaud et al, 2009). Therefore by understanding the environmental conditions that promote the growth of a successful RSA we can ensure the development of a healthy plant. Figure 1 – Root Structure Architecture (RSA) taken from â€Å"Root-System Development and Water-Extraction Model Considering Hydrotropism† by D. Tsutsumi et al.   Arabidopsis Thaliana Like many other research projects, Amtmann’s group uses the plant Arabidopsis Thaliana within their investigations. Arabidopsis Thaliana is considered to be a model species within plant science and biology as its genome was sequenced in 2000, meaning that its complete DNA sequence was determined (Wikipedia, 2011).   As the genome is relatively small it is easier to work with and analyse. It is also closely related to a large number of other plants such as (Somerville and Koorneef, 2002) meaning that any finding could be widely applicable. It can also be easily grown in laboratory conditions due to its small size and straightforward growth conditions. As a result of the Arabidopsis Thaliana sequenced genome, scientists can determine which genetic combinations are responsible for certain characteristics of the plant, such as the direction of root growth or number of lateral branches.   Figure 2 highlights some variation in roots of Arabidopsis Thaliana. Figure 2 Different Root Structure Architecture for Arabidopsis taken from unil.ch/dbmv/page36242_en.html Currently Dr Amtmann’s group grows multiple instances of Arabidopsis Thaliana in square agar plates that allow them to take two-dimensional images of the plant roots as it grows.   These images are then examined using a bespoke system called EZ-Rhizo, which was developed by Dr Amtmann’s Research Group, to determine the RSA of the plant. EZ-Rhizo EZ-Rhizo is freely available software that detects and measures the RSA of a plant quickly and accurately (Armengaud et al, 2009) when supplied with an image of a root system. It was developed by Dr Amtmann’s Research Group in conjunction with undergraduate students from l’Ecole Supà ©rieure dIngà ©nieurs en Electrotechnique et Electrique in 2008.   The main function of the system is to measure information about the main root and the lateral roots of a plant, and record this. All numerical values are stored in centimetres.   It then uses this data to derive further parameters such as the apical zone or straightness of the root. The key parameters that are captured by EZ-Rhizo in relation to this project are as follows: Apical Zone, which is the length of the root between the top of the main root and the oldest lateral root Length, which is the total length of the root from the origin of the main root to the tip of it.   (Note that as roots do not grow straight this value may be very large but the root may not have grown that far towards the ground) Vector Length, this is similar to the length however it calculate the shortest possible length of the root starting from the origin of the main root to the tip of it. Straightness, which is the Vector Length, divided by the Length. Angle, which is the degree between the Vector of the root and complete verticality. A full listing of all the parameter capture by EZ-Rhizo can located in the in that’s publication The system was developed for the Microsoft Windows operating system and stores data in a MySQL database. Queries can then be submitted to the database, which will retrieve all of the stored data for a specified root and output it into a Comma Separated Values (CSV) file (Armengaud et al, 2009). Project Objective As previously described, the main method used by Dr Amtmann’s Group to analyse and compare the plant root data, recorded by EZ-Rhizo, is to gather the required CSV files and generate the appropriate graphs in Microsoft Excel. The current methods used by this group can be extremely time consuming and could be subject to error if mislabelling on a graph occurs or if a value within a CSV file is misread. As the team work with large quantities of data there is a high probability of this occurring.   Also, the format of the results could also inhibit certain comparisons, as the visualization of the roots is limited to the graph format. Therefore the aim of this project is to design and implement a new system that will enable Dr Amtmann’s Research Group to overcome these difficulties. The proposed system will allow them to analyse and visualise their root data, collected from EZ-Rhizo, in a more flexible and reliable manner. The basic functionality of this system will be to create a realistic visualization of a root based on the supplied parameters. This will provide the foundation for developing alternative visualizations but it will also allow the researchers to understand the data that EZ-Rhizo is recording. As the system will re-create the root system architecture based on only the values provided by EZ-Rhizo, the re-creations will highlight which characterises of the root can be displayed. Therefore, once the visualizations have been created it may show that more root data is required to be captured by EZ-Rhizo in order to for the root system architecture to be properly documented.   This verification could not be achieved from a graph of the values or from viewing the original root structure image that is supplied to EZ-Rhizo. Once the basic functionality of this system is operational it can be enhanced, by the use of prototypes and experimentation, to find suitable techniques that allow for a meaningful representation of more than one root. For example, the average value of each parameter could be determined for a set of roots and the system could draw the average root. Alternatively given the parameters for a set of roots, the system may be able to estimate a root visualization that had all of those parameters altered by a set value and so produce a theoretical root.   Estimations of this nature would not be possible using the group’s current graphical techniques. In summary, the objective of this project is to implement a system that will create interesting and realistic visualizations of plants root system architectures that will be used by Dr Anna Amtmann and her Research Group in their experiments. 3. Background Survey Development Language One of the functional requirements that was supplied by Dr Anna Amtmann’s Research Group during the initial discussions of this project was that they require this system to be multi-platform, unlike EZ-Rhizo, which was specifically designed for Microsoft Windows Operating Systems. As a result of this requirement and the author’s previous development experience, the Java development language has been selected for this project.   As Java is a cross-platform language that be run anywhere, as long as the Java Virtual Machine (JVM) is present, it meet the requirement set by the Research Group.   Also, as a main priority of this project is to develop and experiment with the greatest number of prototypes, it is advisable to reduce the learn curve that would be required in understanding a new language and so as Java is the developers strongest language it has been selected. Drawing packages Java 2D The Java 2D is a freely available drawing framework that allows for the construction of two-dimensional images (Wikipedia, 2011) and is part of the core Java Standard Edition Application Programming Interfaces (APIs) developed by Sun Microsystems, and now maintained by Oracle (Oracle, 2011).  Ã‚   The key strengths of this API are that it supports the drawing of basic shapes such as rectangles and ellipses but also basic lines, which is required for this project. Also, it will export any images created into well-known formats such as JPEG or GIF (Sun Developer Network, 2011).   As this is a JAVA API there is also a great deal of implementation support provided. OpenGL Open Graphics Language (OpenGL) is a mutli-platform API for creating two-dimensional or three-dimensional graphics (OpenGL, 2011) that is now considered to be an industry standard for graphical development. Currently OpenGL can be used with a number of development languages including Java (JOGL), Python, C++ and C.   As this project will be constructed in Java, JOGL would be the appropriate selection and since the release of Java Standard Edtion 6 in December 2006, JOGL and Java 2D can be used concurrently. However, one limitation of JOGL is that it will add complexity to a if the developers has no previous experience with this API as it currently has 250 different function calls for drawing one image (Wikipedia, 2011). JHotDraw Fractal Dimension One of the key elements of the root visualization is to get it to be as realistic as possible. Now it is likely that the root will be drawn out of straight lines how it will be essential that Alpha Blending Visualization Uncertainty 4. Proposed Approach The suggested approach for this project will involve designing and implementing a basic system that contains all of the functionality required to visualize one root based on the information provided from EZ-Rhizo. Upon successfully implementation of this initial system, a number of prototypes will be created around techniques, such as Alpha Blending, that will manipulate this functionality to draw clusters of roots or alter the initial visualization to provide a different perspective for the user. Any prototype functionality that is considered to be useful, interesting or successful will then be fully integrated into the main system as additional functionality. Basic Functionality It is likely that the new system will send requests directly to the database to retrieve this information rather than obtaining this from CSV files. However this functionality will be discussed with Dr Amtmann’s group during the design phase of the basic system alongside all other functional and non-functional requirements This system will only work with data from EZ-Rhizo at this time and it is assumed that the parameters will be from Arabidopsis Thaliana JAVA – it needs to be multi-platform unlike Ez-rhio   and JDBC Additional Functionality Currently at least two general prototypes have been envisioned with the following functionality Being able to represent average values for root parameters, such as length, and display them in a readable and understandable manner Being able to represent the lifecycle of a root based on the parameters recorded on the first day of growth to the last. It is likely that each of these general prototypes will have sub-prototypes that will evaluate techniques that display the information to achieve the objective. After the more successful techniques have been identified they will be developed and presented to the research group to confirm if they still wish this prototype to be included. Design Methodology To ensure the success of this project, the implementation of this project will follow an iterative software development methodology of design, implementation and testing.   This has been selected because one of the key components of this project is to build upon a basic system. It is therefore essential that this be successfully deployed before introducing any further functionality from desired prototypes. Due to this requirement the selected methodology will be The Spiral, which supports iterations and constant reviews and refinements as shown in Figure 3. It is also vital to review each prototype after it has been implemented to ensure that the original functionality has not been compromised. Figure 3 – Spiral Software Development Methodology taken from http://as.exeter.ac.uk/divisions/exeterit/iws/projects/ede/ Risk Analysis As with any software development project there is a certain element of risk in undertaking the assignment, and the key risks identified within this project are as follows: Terminology Due to biological terminology involved in the understanding of the system requirements there is a possibility that these may be interpreted wrongly. Therefore it is imperative that this be considered at every stage involving an element of design, and clarification will be sought if any ambiguity arises. Time Constraints As this project is due to be completed over a 15-week period there is potential for the project to overrun at any point and so continual review of the work plan is required. The stage with the highest potential for delay would be that of developing and testing prototypes.   Once the initial prototypes have been produced there is a possibility that revision will be required after discussions with Dr Amtmann’s Research Team.   Where possible all prototypes will be implemented to the highest standard however at a given point the further development of the prototypes will have to be discontinued. Regular discussions with Dr Rogers and Dr Amtmann regarding this should identify a suitable stopping point and prevent the project from suffering from delays. 5. Work Plan This chapter will detail the provisional work plan for this project and it has been estimated that work will begin on 20th June 2011.   Please note that weekly meetings will be scheduled with Dr Simon Rogers during this time and there will be a high level of communication between Dr Anna Amtmann’s Research Group and myself. Figure 4 – Gantt Chart Showing Estimated Project Timescale The following sections detail the work that will be done in each phase of the project as shown in the Gantt chart in Figure 4. Background Research During this time I will study the areas identified in section three in more depth and review this background research.   At this stage I will also investigate further techniques that could be used to develop additional prototypes that could be used to manipulate and display the root data in an interesting manner. Deliverables: Revised Background Section Critical Rating: Preferably Risk Factor: Low Requirements Capture This stage will involve identifying and creating a detailed list of the functional and non-functional requirements of the system.   During this time a requirements document containing the appropriate UML diagrams will be developed and will be approved by Dr Simon Rogers and Dr Anna Amtmann before any implementation begins. Deliverables: A clear requirements document Critical Rating: Important Risk Factor: Medium Implementation of the Basic Functionality After the basic requirements of the system have been determined they will be implemented in an application. At this stage, the system should at a minimum be able to use the data from EZ-Rhizo and create a visualization of at least one root. A test plan will also be created at this time. Deliverables: Implementation of Basic System and Test Plan Critical Rating: Fundamental Risk Factor:   Medium Testing of Basic Functionality This stage will ensure that the basic system is operational and that all of the functional requirements have been achieved.   This may involve getting feedback from the Plant Science Group depending on their availability and whether or not they wish to test the completed project. Deliverables: Critical Rating: Important Risk Factor: Low Design and Build Prototypes The next section will involve developing prototypes that manipulate and display the root data in various interesting manners.   Each prototype will involve a technique identified previously in section three or found within the further research conducted at the beginning of the project plan. Deliverables: A number of prototypes that modify the visualization of a basic root Critical Rating: Fundamental Risk Factor: Low Experiments with Prototypes At this time Dr Amtmann and her team will review the prototypes with a follow up discussion with Dr Rogers and myself to confirm that they capture useful information.   At this time, depending on time constraints, additional prototypes may be developed based on the discussions, however this will be reviewed at the time. Deliverables: A list of prototypes that are deemed to be visually interesting and useful Critical Rating: Preferable Risk Factor: Medium Integrate desired Prototypes Any prototypes that are deemed to be successful will then be integrated into the basic system.   This will be completed in iterations, with testing being conducted after each integration to ensure that the new prototype does not break the basic system. Deliverables: Critical Rating: Important Risk Factor: High Testing of Additional Functionality Once every prototype has been implemented successfully, further testing will be conducted to ensure that the original functionality still meets the initial criteria and that the prototype functionality is producing valid and interesting results.   At this stage a small user evaluation may be conducted to ensure that the user interface developed for the system is successful. Deliverables: Critical Rating: Important Risk Factor: Low Complete and Submit Dissertation Finally, a dissertation documenting the work that has been undertaken will be composed and will be approximately 60-70 pages long.   It will be submitted on the 6th September 2011.   During the project, work will be provisionally documented to ensure an easier transition from implementation to documentation.

The Philosophy of Honesty

The Philosophy of Honesty What does it take to be honest? Although often invoked, the concept of honesty is quite tricky to characterize. Taking a closer look, it is a cognate notion of authenticity. Heres why. Truth and Honesty While it may be tempting to define honesty as speaking the truth and abiding by the rules, this is an overly-simplistic view of a complex concept. Telling the truth- the whole truth- is at times practically and theoretically impossible as well as morally not required or even wrong. Suppose your new partner asks you to be honest about what you have done over the past week, when you were apart: does this mean you’ll have to tell everything you have done? Not only you may not have enough time and you won’t recall all details, but is everything really relevant? Should you also talk about the surprise party you are organizing for next week for your partner? The relationship between honesty and truth is much more subtle. What is truth about a person, anyway? When a judge asks a witness to tell the truth about what happened that day, the request cannot be for any particular whatsoever but only for relevant ones. Who is to say which particulars are relevant? Honesty and the Self Those few remarks should be sufficient in clearing up the intricate relationship there is between honesty and the construction of a self. Being honest involves the capacity to select, in a way that is context-sensitive, certain particulars about our lives. At the very least honesty requires an understanding of how our actions do or do not fit within rules and expectations of the Other- where the latter stands for any person we feel obliged to report to, including ourselves. Honesty and Authenticity But theres to the relationship between honesty and the self. Have you been honest with yourself? That is indeed a major question, discussed not only by figures such as Plato and Kierkegaard, but also in David Hume’s Philosophical Honesty. To be honest to ourselves seems to be a key part of what it takes to be authentic: only those who can face themselves, in all their own peculiarity, seem to be capable of developing a persona that is true to herself- hence, authentic. Honesty as a Disposition If honesty is not telling the whole truth, what is it? One way to characterize it, typically adopted in virtue ethics (that school of ethics that developed from Aristotle’s teachings), makes honesty into a disposition. Here goes my rendering of the topic. A person is honest when he or she possesses the disposition to face the Other by making explicit all those details that are relevant to the conversation at issue. The disposition in question is a tendency which has been cultivated over time. That is, an honest person is one that has developed the habit of bringing forward to the Other all those details of his or her life that seem relevant in conversation with the Other. The ability to discern that which is relevant is part of honesty and is, if course, quite a complex skill to possess. Further Readings Despite its centrality in ordinary life as well as ethics and philosophy of psychology, honesty is not a major trend of research in the contemporary philosophical debate. Here are some sources that can be useful in reflecting more on the challenges posed by the issue. The entry on virtue ethics at the Stanford Encyclopedia of Philosophy, where the example of honesty comes up a few times.David Hume’s Philosophical Honesty, a brilliant short piece, too often forgotten.

Employees Performance Appraisal Coursework Example | Topics and Well Written Essays - 1000 words - 2

Employees Performance Appraisal - Coursework Example It is also the process of obtaining relevant information about an employee and determining its worth to the organization by analyzing the given information. The analysis of an employee’s performance involves its recent accomplishment in the organization, its deficiency, strengths and weakness to determine whether the employee is suited for promotion or needs to be retrained. In short, Performance Appraisal measures the actual performance of an employee in an organization of what it has already done, of how productive an employee is; whereas Potential Appraisal determines the future capabilities of an employee that can be used to optimize its manpower or to determine ability to assume varying or greater responsibilities. 2. Discuss the linkage between ''Potential Appraisal'' and ''Career Development''. (200 words)   Through Potential Appraisal, the company will be able to better match its human resource requirement with the career goals of its employees. As an employeeâ€℠¢s potential is â€Å"unlocked† through Potential Appraisal, the employee is given the chance to develop itself to advance its career in the organization and fulfill its career objective. ... sal a certain aptitude or inclination towards a skill set that is more needed in an organization, the employee may be groomed to undertake such career path for greater chance of advancement. For the company, it is able to optimize the capability of its workforce. Through Potential Appraisal, the company is able to place or match its employees in a job function that it has an aptitude or more motivated to perform. This will result in a workforce that is working efficiently while fulfilling the career goals of its employees. 3. Identify the manager's main responsibilities when conducting Potential Appraisal. (200 words). In conducting a Potential Appraisal to a prospective employee, it is the responsibility of the Manager not only to identify the possible qualities and skill sets of an employee that can be enhanced for future responsibilities but also to explain how these identified qualities and skill sets can be developed to be utilized on the current job and future responsibilities. It is important to note that in conducting a Potential Appraisal, it is the sole responsibility of the Manager to conduct feedback as to the result of the appraisal and provide counseling to the employee when a prospective weakness has been identified in the course of conducting a Potential Appraisal. Identified strength of an employee can be used by the Manager in the process of planning the career development of its employee. In the course of providing feedback to the employee, the Manager can help draw the right career path whereby its employee can pursue and realize its optimum potential. This way, the Manager is also to do proper job-matching by placing the right individual in the right function. In a case of identified deficiency, the Manager can recommend training whereby the

Care n Christian Communities Essay Example | Topics and Well Written Essays - 250 words

Care n Christian Communities - Essay Example the rope have responsibility over the other, but individuality and the reactive process divides the individuals responsibility over whether to hold onto the rope, or to pursue his passion (Richardson 26). The two people cannot be the same person. This is because they are dressed similarly, but one has a rope tied on his or her waist. They were also coming from different directions. Their difference in thoughts also suggests that they have totally different personalities. One person is wise while the other does not demonstrate wisdom in his words (Richardson 80). In this fable, the person holding the rope empowers the one suspended to make a decision. The man who is suspended by the rope is empowered to make a choice between helping himself and being set free. The suspended person is, therefore, the ultimate decision maker (Richardson 67). One can identify their role by analyzing the situation they encounter. This can be done by judging ones responsibility, and whether the other person is willing to participate in that responsibility. It is equivalent to taking leadership in a situation. I contribute to new possibilities in such situations by offering options or choices that can be made (Richardson 180). One core concept of family systems theory is communication. Family systems use regulatory patterns of interaction and communication in the process of adapting to external and internal changes, and this leads to development of rules and roles governing individuals. In this fable, the two individuals must interact in order to come up with a solution. They both have to make contributions in order to overcome the situation they are facing. One person has to hold on tight while the other has to make a choice of pulling himself up. This core concept provides a compelling view that suggests individual are affected by societal patterns, and they have to contribute to it (Richardson

What Features Should be Included in Online Examination System With the development of the Internet technology, online examination has become more and more poular since it helps people save much energy and time. As an efficient and effective way of teaching and learning, online examination can prevent from cheating and ensure the fairness of the examination results. A good examination system should be developed based on the needs of a real examination. Here are some features an examination system should provide: Examination Instructions The examination instructions will show the basis contents of the examination and something that should be paid attention to. Usually the following elements such as total questions, full score, passing rate, passing score, time limit, etc. are included in the instructions page. Accessibility of Examination Content Preset accounts and passwords can be set to protect the contents. And participants can register themselves online. Only authorized users can take the assessment contents. What’s more, domain hosting limitations can be set. Even if the participants have downloaded the flash assessment, it can not be played. Valid Time of Examination Content The participants can log in the examination system with their accounts and passwords to access the relevant page to complete the testing in the valid time. The examination will be unavailable when the valid time expires. Time Limit of the Examination Participants may log in the system to take the examination after the start time. When the testing time is used up, the examination results will be submitted by participants. Even if the examination is not completely finished at that moment, it will be submitted to the reporting system too. The start time and end time will be recorded precisely in seconds. Time Reminder for the Examination The time reminder will tell the participants how much time left during their examination. When it comes to the end of the testing, some alter audio will remind you of submiting your examination paper. Submission Ways Two ways to submit your answers to the reporting system: 1. Submit one question at a time. 2. Submit all at once. The former one means the participants can not review and modify their answers to their submitted questions. However, with the latter way of submiting, the participants can review and modify their answered questions before they submit the final answers. Result Release Immediate release or timed release can be set to the examination. For some examinations consisting of objective questions, the scores can be calculated automatically when the testing is over. The participants can view the results instantly. If you don’t want the results to be viewed so early or there are some subjective questions needs manual grading, you can finish the grading job first and then the participants can visit the system website to check their testing results. Chapter 1: Preliminary Investigation about Existing System 1. 1 INTRODUCTION Modern technology has added a new ingredient to this mix the Internet. The Internet can be regarded as a cheaper and improved version of the self-education resources. Some people like to take exam in a classroom is traditional manual examination because they are happy to sit there and have the teacher tell them what to learn, and when they get stuck, they are happy that there is someone there to help them, and they enjoy the social environment while taking exam. The traditional approach to measuring a persons level of knowledge in a topic has been the examination. These days there is often more emphasis on internal assessments, which may consist of assignments and projects given out and then marked or assessed. However examinations remain a popular component of many assessments. Source: Phillip Dorrell (2006) The author have noticed that most students wanting to acquire an admission into higher problems usually find it hard to achieve because those institutions make it a requirement to for the students to attain English certification which would verify that the students do speak and understand English. In order to help students acquire these scores, the author took it as a challenge to develop a test engine which would allow students to get the scores with ease. Examinations have the advantages of confidence that a large number of students are all being assessed equally and reduced opportunity for cheating. Users can use the system for writing the test and know about the system functionality. An individual can make use of the system by login in and taking a test. The main aim of carrying out a preliminary investigation is to attain much knowledge about understanding of problem, defining the project scope and constraints, identifying the benefits, estimating the time. Manual Exam Manual Exam is sort of an assessment that is intended to measure an individuals knowledge, skill and aptitude of a certain student or individual. This is also commonly known to test takers as â€Å"Written Tests† and is a manual exam developer’s choice of which style or format to use in creating and developing a written administered on a sheet of paper. A test taker who takes a written test could respond to such specific test items by writing it down manually within a given space of an examination paper or any separate sheet of documenttest is usually given that there is no such standard of testing. Be that as it may, certain exam style format have become widely used than others. Online Exam Online examination is an assesment that use network connection or internet in its process. Individuals and students must sign in on an assessment program or web link by entering their username and password. Then they choose the course that will be tested and the student start answering the questions that is shown on the screen. After they have finished the examination, the student taking the exam must click on a certain button that would require finishing the examination process. Even though this seems easy, online examination has its advantages and disadvantages as well. The students who agree that online examination is good has many advantages. Online examination can make the student’s life easier because they don’t need any paper and pen to do the examination. Furthermore, online examination can be effective and efficient. The students don’t waste much time to answer the questions because they only click on the best answer that is provided. One other advantage of online examination is that we can know our scores just after the exam. Sometimes, instructors can be very busy on a given day and do not have any time to check the exams. Online examination can solve this problem. The instructor does not need to check all of the exams. Online examination can do

The Continuant Domination of The Aboriginal People Essay -- Canada Can

The Continuant Domination of the Aboriginal People In any Canadian history class we learnt about how the Europeans settled in Canada to build a new life. Furthermore, as kids we have always learnt that Christopher Columbus had discovered Canada as an empty piece of land, with no habitants whatsoever. (Flashback Canada, 1994) These statements are false. Native Canadians had already been living in Canada, and the European settlers basically just moved tight in regardless. Setting up their own Government, and being the aggressor in the country took control of everything the aboriginals had. It was said that to the aboriginals it looked like â€Å"mercantilists wanted our furs, missionaries wanted our souls, colonial governments, and later, Canada, wanted our lands.† (Razack, 2002) The purpose of this paper is to show how the government of Canada, also known as the majority has taken advantage of the native peoples of this country. This has happened in many ways, but one of the most important techniques is land control. In addition, the treatment of the aboriginal people in Canada demonstrates how the dominant group utilizes the technique of land control to dominate the minority group. This is can be seen though the forcing of the native people to relocate, how the government responds to land claims made by the natives, and how the aboriginals have to settle for insufficient land. Throughout history in Europe, there was a concept of inalienability of sovereignty, meaning that people who were inhabitance of a colony firstly, did not have to adapt to ways and laws of other settlers. (McNeil, 2002) This was not the case when European settlers came to Canada, and forced the concept of assimilation upon the aboriginals who already resided in the country. The dominant group forced them to relocate to reserves, and as well forced them to abide by their laws, even though it was not based on the political philosophy of Europe. Reasoning being, the government wanted to have control of the land that was occupied by the Indians, because the government could use the land to develop business which can help them build the economy. (Aboriginal Rights Coalition, 1999) In addition, any resources that were available would be controlled by the dominant group, because they wanted to have control of the resources, because it could be used in trade with other countries. (Abor... ... great financial affect upon the aboriginals. This was just another technique used, by the government to stay on top. Even though they were given some land by the state, it was insufficient land to live on and the natural resources that the aboriginals required to have a good state of living were altered purposely, and nothing the aboriginals could do about it. In addition, even though things are getting a little bit better for the aboriginals, it will take a lot of compensation to make up for the years and years of dreadful treatment.

Explaining the role of effective communication Essay

There are wide ranges of ways that communication can take place for example one to one conversations, group conversations. This can either be informal or formal depending on the individual’s outcome. An example of effective communication that can take place in a health and social care setting is a hospital, for example a nurse and her colleague are talking about how much they enjoy their jobs, and this is a form of effective communication. One- To –One communication – A one to one happens when a person speaks to a individual, or writes to the individual to form effective communication. In a one to one communication, it is always effective as both of the people in the one to one work together effectively and interacts well, as both individuals are relaxed and are listening to each other, in a result the communication works effectively and both parties leave with a resolved matter and everything is positive. One to one communication can be formal or informal. An formal one to one communication can take place in a GP, where the patient is discussing their personal problem with the Doctor and the doctor is helping the individual out with their problem, this is part of effective communication as the one to one interacting is working effectively. An informal one to one communication, can take place in a health and social care setting, where two colleagues are on their lunch break and are discussing about how their day has gone so far and etc. ,this is a part of effective communication as both parties are interacting effectively. Group communication – In a group communication, there is often more going on as it is a wide range of people within the group. During the group communication, each individual will try and get their points and ideas across to the people within the group and the rest will listen and be considerate towards the person speaking. That is a way of effective group communication, as the interacting between the group is working well and effectively. A group communication can be a great benefit, as it’s easier to make decisions and problem solving a ituation as you have various people giving different views and feedback to a matter, and that’s a great way of effective communication. A group communication can include multi- professional working, multi-agency, which happens with professionals and people using services. A multi-professional working involves numerous professionals working together in order to meet the needs of an individual. This will include doctor, police, an d social worker to meet the needs of a young adult in a bad situation. Multi-agency is when different organisations work together effectively to the best possible service to families, children and young people. Formal communication Formal communication is a form of communication used by professional to communicate with clients and individuals. This form of communication is important because it shows the professional is showing professionalism within the work their doing to deliver the best possible care for the individual as well as the communication working effectively. An example of formal communication can be, ‘ good morning Sir/Mrs, this shows respect towards the individual. It is important not to use jargon or slang whilst communication formally, because you will come across as you’re not serious about your work, and also the client my not be pleased, also jargon can be a barrier because it can affect the communication between the client and professional due to not understand the technical words. Informal communication Informal communication is a casual exchange or letter that doesn’t follow to all of the rules of formal communication. It’s like saying â€Å"hey† instead of hello and also writing to your friend and talking about personal things. These are things you’d never do in a business environment because it can be considered as formal communication. Informal communication is good way of communication as it can make a individual more relaxed and effective as it’s more easier and complex for the person to interact, as they don’t have to worry about being proper and correct. Interpersonal interaction Interpersonal interaction is how people relate towards each other in a verbal nteraction or non-verbal interaction. Verbal interactions include speech, tone of somebody’s voice, listening and language. Non-verbal interactions include a person’s body language and the way they express it for example their posture, facial expression and their proximity. Interpersonal communication can take place in a health and social care setting, for example: at a care home, there is a new career and she does not speak English properly, so therefore it is hard for her to interact with the residents, which makes this is a language barrier. P2 – Argyle’s Theory of the Communication Cycle Michael Argyle is a social psychologist who developed theories about interpersonal interaction and human communication. He carried out experimental theories of non-verbal and verbal communication to develop and test he’s theoretical ideas. He has a communication cycle which explains and predicts how communication can occur in a one to one situation. 1. An idea occurs. A resident wants to go to the library and is trying to convince her carer. 2. Message coded. She talks to her carer about the books she used to read and how much she misses reading them. 3. Message sent. The carer says to the resident, ‘what was your favourite book’ this shows the message is sent and the carer understands what the resident is talking about. 4. Message received. Now the carer know what the resident’s favourite book is the resident is happy and is smiling. 5. Message decoded. Then the carer says to her resident would you like me to take you to the library so we can have a look if they have your favourite book and other books your interested in? 6. Message understood. Here the resident is happy and so is the carer because now they both understand each and the communication between the two has worked effectively. Bruce Tuckman defined a model of group development based around numerous stages, sequences or group activity. Tuckman suggested that these stages should happen in order for effective communication to occur in the groups interaction as well as the four stages being completely different. Forming –it is the start of the year and new infants have started the nursery, they tend to be shy and well reserved as they are not used to each other. Storming – as they start to settle in for about a month, they because more comfortable and relaxed with each other, in some cases this might not happen, someone would want to be dominant out of the bunch and this may cause conflict between the infants. Norming – in this stage everyone had built a strong bond between each other, and is working together well. Performing – in this final result the infants become mature and tend to realise that working together effectively can be a positive thing. M1 – Assess the role of effective communication and interpersonal interaction in health and social care with reference to theories of communication. The roles of effective communication in a health and social care setting, is to ensure that if communication with a resident, you must make sure to talk clearly and slowly, face to face make sure the person understands you and you’ve got your message across in the right way, in order for the communication to work effectively. The types of reference to communication are sign language, makaton and braille. These are part of effective communication as they are used by people with a hearing or blind impairment and leaning difficulties in order for them to communicate with others around them. Effective communication is a two-way process in which a person tries to understand the viewpoint of the other person. Communication is a cycle because when two people communicate they will need to make sure that they got their ideas across towards each other and they are understood. There are also barriers that can occur in a communication due the individual’s circumstance, for example: a person using slang, jargon o complex technical terminology can be heard, but their message may not be understood. Scenario I’m going to give a scenario between doctor and a patient, showing communication working effectively. Nurse : did you rest well last night Mrs Jones? Patient: yes I did nurse, I’m feeling slight better. Nurse: that’s a great improvement then, I’m glad you are. Patient: thank you very much nurse. Nurse: I am always here to help my dear. This is a very good way of effective communication, as the nurse and patient are interacting well and both parties are happy as they have understood each other.

Maoism in China Essay

Generally, the Communist system in the Soviet Union and in China are practically identical politically, economically, with the reciprocal purges ect†¦ However, Mao Tse-Tung and Stalin did not see eye to eye on many things and Maoism is considered today by most people to be a more developed stage of Marxism-Leninism. This is because of the historical and cultural background of China and because of her geographical position and climate which affects society. Contrary to Russia, Communism developed in the countryside instead of in the cities. Thus it was a peasants’ revolution rather than, as predicted by Karl Marx, a workers’ revolution. The cities in China were at the beginning, anti-Communist. The Chinese absorption of Marxism was highly selective. China took from Marxism those aspects which best suited the Chinese situation rather than force the Chinese situation to fit an overachieving ideology. Thus Marxism was to be the servant of the Chinese Revolution. Mao Tse-Tung believed that adherence to pure Marxist theory would be suicidal and concluded that proletarian revolution based upon the urban areas was impossible in China since 80 percent of the people were peasants. Due to the warmer climate and more fertile land, peasantry was more popular in China. This pragmatic solution led to the Revolution starting in the rural areas. The most important difference between Stalin and Mao is the comprehension of the word ‘proletariat’. The Russians believed it meant, as Marx had, the industrial workers while the Chinese, by lack of sufficient workers, understood it as the peasantry. The Great Leap Forward where everyone was put to work was another Maoist characteristic. For 100 days each year, the peasants were not working in the fields so Mao set them up to work in the off-season harvest after 1957. Millions of men and women were put to work in winter, digging irrigation ditches and canals, preparing railroads and laying track. Then the â€Å"backyard furnace† was invented and 600 000 small steel establishments were set up.  The object was to overtake Britain in steel production. However, when the peasants left their land to work on the industrial projects, the lands suffered. So more changes were made. In some communes, men and women were separated to increase their productivity by cutting down socialising. On February 27th 1957, Mao was feeling very positive about all that he had done so he decided to loosen the straps on the Chinese people. He introduced the ‘hundred flowers’ campaign where he encouraged arts, sciences and â€Å"a flourishing socialist culture in our land. Different forms and styles in art should develop freely†. It seemed he was encouraging free thought and criticism of the system. After only six weeks though, Mao’s open invitation brought a real storm of furious criticism from the intellectual community who believed the chairman was sincere. This infuriated Mao who was expecting positive feedback and in April 1957 a rectification campaign had begun to eliminate the ‘triple evils’: â€Å"subjectivism, sectarianism, and bureaucratism†. The party members and Mao believed to be above criticism so a purge of intellectuals began. The Cultural Revolution is perhaps the greatest difference between Stalinism and Maoism and was entirely set up by Mao Tse-Tung. He has been called insane many times for the crazy extent which the Cultural Revolution took and for the lasting and devastating effects it continues to have. Mao favoured the word, â€Å"destruction† when he promoted the Cultural Revolution; he preached that he had to destroy an old system of production, an old ideology and old customs first. He thought that once the ideology had been established, productivity would follow in a revolution. â€Å"Although the bourgeoisie has been overthrown, it is still trying to use the old ideas, culture, customs and habits of the exploiting classes to corrupt the masses, capture their minds and endeavour to stage a comeback. The proletariat must do the exact opposite: it must deal merciless blows and meet head-on every challenge of the bourgeoisie in the ideological field and use the new ideas, culture, customs and habits of the proletariat to change the mental outlook of the whole of society. At present, our objective is to struggle against and overthrow those persons in authority who are taking the  capitalist road, to criticize and repudiate the reactionary bourgeois academic authorities’ and the ideology of the bourgeoisie and all other exploiting classes and to transform education, literature and art and all other parts of the superstructure not in correspondence with the socialist economic base, so as to facilitate the consolidation and development of the socialist sy stem.† Fifteen years after the success of the Revolution, Mao saw his new society as troubled, he had destroyed the old ruling class, but had established two new ones: the intelligentsia and the bureaucracy. Mao had turned against the intelligentsia after the ‘hundred flowers’ campaign but had not finished destroying them. When he saw the Soviet Union’s new aristocracy with their dachas and limousines, he set out to destroy the establishment he had created. Always one to manipulate the masses, he turned towards the youth for a new society by creating the Red Guard, an army of children. They were sanctioned by the highest authority, Mao himself and were bent on destruction. In essence, the children destroyed anything which did not appeal to them, although the initial target was to destroy the ‘four olds’: ideas, culture, customs and habits. They travelled in bands for mutual protection and inspiration, destroyed stores and restaurants and attacked however they desired. The Red Guards were divided by family background: poor peasants against well-to-do peasants, peasants against workers, and the children of army officers. The next step of the Cultural Revolution came in January 1967 when Mao replaced the officials all over China by young people with no experience and no common sense. Then universities, middle schools and primary schools closed down. This was called the period of the terror. The only young people to receive an education were the children of intellectuals who were taught by relatives and parents. Mao tried to destroy the education process which was disastrous for China as specialist, technicians ect†¦ were indispensable for the development of a country, and in this case, they were dismantled. However, he changed his mind in 1978 and sent in the People’s Liberation Army to desman the Red Guard. Mao’s theory of constant revolution to avoid the forming of classes is the major separation with Leninism and Marxism. It was under these conditions that the most earthshaking political event and the largest mass mobilization the Earth has ever seen took place. This is how Chairman Mao defined its objectives: â€Å"The current Great Proletarian Cultural Revolution is absolutely necessary and most timely for consolidating the dictatorship of the proletariat, preventing capitalist restoration and building socialism.† Mao’s Communism focuses especially on the particular interest for China and this by rejecting foreign intervention. The only use for foreign involvement is to insure Chinese security, economy†¦ He believes in Chinese Communism first, and not in World Communism. However, China supports people threatened by oppression which explains their expansion policy. Indeed, China has expanded her territory by invading the Tibet, fighting Korea. China has refused economic aid, except for trade with the Soviet Union which represented only 2 percent of Chinese investments. China developed its own brand of Communism to suit its needs and similarly to Stalinism, was dictated by only one man, who had the power to decide anything he desired.

Cave Hyena Facts and Figures

Cave Hyena Facts and Figures Name: Cave Hyena; also known as Crocuta crocuta spelaea Habitat: Plains of Eurasia Historical Period: Pleistocene-Modern (2 million-10,000 years ago) Size and Weight: About five feet long and 200-250 pounds Diet: Meat Distinguishing Characteristics: Long hind legs; strong jaws with sharp teeth About the Cave Hyena (Crocuta crocuta spelaea) Its not quite as well known as the Cave Bear or the Cave Lion, but the Cave Hyena (Crocuta crocuta spelaea) must have been a common sight in Pleistocene Europe and Asia, to judge by this megafauna mammals numerous fossil remains. As you can guess from its name, this hyena liked to drag its kill (or, more often, the kill of other predators) back to its den, for which purpose it was equipped with longer, more muscular hind legs than contemporary hyenas (of which the Cave Hyena is now classified as a subspecies, rather than a separate species as had previously been thought). One network of caves in Europe has yielded tantalizing evidence about the Cave Hyenas favorite prey animals, with Przewalskis Horse and the Woolly Rhino ranking high up on the dinner menu. Like most opportunistic predators of the Pleistocene epoch, Cave Hyenas occasionally preyed on early humans and hominids, and they werent shy about stealing the hard-earned kill of packs of Neanderthals (which might well doom them to starvation). Where Crocuta crocuta spelaea and the ancestors of modern humans really mixed it up was in the competition for habitable space: paleontologists have identified caves that bear evidence of alternating populations of Cave Hyenas and Neanderthals, a pattern that evidently repeated itself over thousands of years. In fact, the Cave Hyena may have been doomed by the encroachment of early humans on its rapidly dwindling caves, which grew even scarcer after the last Ice Age, about 12,000 years ago. Like many other animals with which our ancestors shared their hard-won territory, the Cave Hyena has been immortalized in primitive cave paintings. One cartoon-like representation can be found in the Chauvet Cave in France, dating to about 20,000 years ago, and a small sculpture (carved from the ivory of a Woolly Mammoth!) was created a few thousand years after that. Its likely that both early humans and Neanderthals memorialized the Cave Hyena as a kind of demigod, and also painted it on the walls of their caves in order to capture its essence and facilitate success in the hunt. (Its unlikely that early Homo sapiens targeted the Cave Hyena for its stringy meat, but its pelt would have been valuable in winter, and anyway it was a good idea to eliminate the competition!).

Aqueous Solution Definition

Aqueous Solution Definition Aqueous Definition Aqueous is a term used to describe a system which involves water. The word aqueous is also applied to describe a solution or mixture in which water is the solvent. When a chemical species has been dissolved in water, this is denoted by writing (aq) after the chemical name. Hydrophilic (waters of nonelectrolytes include sugar, glycerol, urea, and methylsulfonylmethane (MSM). Properties of Aqueous Solutions Aqueous solutions often conduct electricity. Solutions that contain strong electrolytes tend to be good electrical conductors (e.g., seawater), while solutions that contain weak electrolytes tend to be poor conductors (e.g., tap water). The reason is that strong electrolytes completely dissociate into ions in water, while weak electrolytes incompletely dissociate. When chemical reactions occur between species in an aqueous solution, the reactions are usually double displacement (also called metathesis or double replacement) reactions. In this type of reaction, the cation from one reactant takes the place for the cation in the other reactant, typically forming an ionic bond. Another way to think of it is that the reactant ions switch partners. Reactions in aqueous solution may result in products that are soluble in water or they may produce a precipitate. A precipitate is a compound with a low solubility that often falls out of solution as a solid. The terms acid, base, and pH only apply to aqueous solutions. For example, you can measure the pH of lemon juice or vinegar (two aqueous solutions) and they are weak acids, but you cant obtain any meaningful information from testing vegetable oil with pH paper. Will It Dissolve? Whether or not a substance forms an aqueous solution depends on the nature of its chemical bonds and how attracted the parts of the molecule are to the hydrogen or oxygen atoms in water. Most organic molecules wont dissolve, but there are solubility rules that can help identify whether or not an inorganic compound will produce an aqueous solution. In order for a compound to dissolve, the attractive force between a part of the molecule and hydrogen or oxygen has to be greater than the attractive force between water molecules. In other words, dissolution requires forces greater than those of hydrogen bonding. By applying the solubility rules, its possible to write a chemical equation for a reaction in aqueous solution. Soluble compounds are denoted using the (aq), while insoluble compounds form precipitates. Precipitates are indicated using (s) for solid. Remember, a precipitate does not always form! Also, keep in mind precipitation is not 100%. Small amounts of compounds with low solubility (considered insoluble) actually do dissolve in water.

Leadership and Managment Assignment Example | Topics and Well Written Essays - 1750 words

Leadership and Managment - Assignment Example e private sector played have played a major role in the English NHS system.2 The Italian Model of Universalism The Italian model was introduced to cover the shortcomings of the English model especially when it comes to selective coverage. It aimed at focusing on introducing a centralized system of financing to allow the government better control of spending. This model saw the introduction of more decentralized health care service provision and introduction of an internal market. The NHS structure in this model consisted of the national government, the regional level and the local authority level of health care provision. The central government’s major task was to oversee how the regions spend their finances and setting the National Health Fund. The local authorities dealt directly with provision of health care services. The main aim was to reduce interegional disparities inorder to maintain a uniform health structure qithin the entire country. This model was not entirely succ essful as a result of poor motitoring and oversight on the part of the central government. There were also problems with funding and increased unemployment rates therefore people not being able to afford health services. These issues led to passing of new laws that would help bring changes and stability in the health sector. The major aim of the laws was to decentralize financial allocation to the local and intermediary level inorder to better meet the needs of the local citizen. This was argued because the local authority would for example better understand the needs of the society as compared to how the central government would.3 Effective Health care governance Health care governance is the process and srtucture needed to ensure better high quality provision of health care services. For... This paper approves that free communication flow using the bottom up and down bottom approach through provision of accessible information sources is among the key strategies that should be adopted by any healthcare organization. This will ensure free feedback from clients, and to enable the staff or colleagues to understand the organization’s policies, goals and objectives in order to be more motivated and enthusiastic towards better provision of services to the public. Focus should be put on transparency of activities to both stakeholders and colleagues. Transparency in communication also helps in giving the staff a clear picture of their tasks and the subsequent outcome. This in turn helps to build their morale and motivation to put more effort to their tasks. Transparent communication makes the staff feel part of the organization or have a sense of ownership. This essay makes a conclusion that application of leadership patterns can be in any organization that has its goals of success merged with the objectives of profit maximization. Managers in a medium sized organization can apply the remarkable pattern of leadership while doing away with the toxic pattern that could result in the firm’s failure and eventual pull out of the industry. Remarkable leadership could be applied by the human resource manager in the organization acting as a coach and training other managers in other departments to act as role models for their followers. The human resource manager can still establish interpersonal relationships with all employees and other manager.
