The Dark Side of Application.ProcessMessages

The Dark Side of Application.ProcessMessages Article submitted by Marcus Junglas When programming an event handler in Delphi (like the OnClick event of a TButton), there comes the time when your application needs to be busy for a while, e.g. the code needs to write a big file or compress some data. If you do that youll notice that your application seems to be locked. Your form cannot be moved anymore and the buttons are showing no sign of life. It seems to be crashed. The reason is that a Delpi application is single threaded. The code you are writing represents just a bunch of procedures which are called by Delphis main thread whenever an event occured. The rest of the time the main thread is handling system messages and other things like form and component handling functions. So, if you dont finish your event handling by doing some lengthy work, you will prevent the application to handle those messages. A common solution for such type of problems is to call Application.ProcessMessages. Application is a global object of the TApplication class. The Application.Processmessages handles all waiting messages like window movements, button clicks and so on. It is commonly used as a simple solution to keep your application working. Unfortunately the mechanism behind ProcessMessages has its own characteristics, which might cause big confusion! What does ProcessMessages? PprocessMessages handles all waiting system messages in the applications message queue. Windows uses messages to talk to all running applications. User interaction is brought to the form via messages and ProcessMessages handles them. If the mouse is going down on a TButton, for example, ProgressMessages does all what should happen on this event like the repaint of the button to a pressed state and, of course, a call to the OnClick() handling procedure if you assigned one. Thats the problem: any call to ProcessMessages might contain a recursive call to any event handler again. Heres an example: Use the following code for a buttons OnClick even handler (work). The for-statement simulates a long processing job with some calls to ProcessMessages every now and then. This is simplified for better readability: {in MyForm:}   Ã‚  WorkLevel : integer; {OnCreate:}   Ã‚  WorkLevel : 0; procedure TForm1.WorkBtnClick(Sender: TObject) ; var   Ã‚  cycle : integer; begin   Ã‚  inc(WorkLevel) ;   Ã‚  for cycle : 1 to 5 do   Ã‚  begin   Ã‚  Ã‚  Ã‚  Memo1.Lines.Add(- Work IntToStr(WorkLevel) , Cycle IntToStr(cycle) ;   Ã‚  Ã‚  Ã‚  Application.ProcessMessages;   Ã‚  Ã‚  Ã‚  sleep(1000) ; // or some other work   Ã‚  end;   Ã‚  Memo1.Lines.Add(Work IntToStr(WorkLevel) ended.) ;   Ã‚  dec(WorkLevel) ; end; WITHOUT ProcessMessages the following lines are written to the memo, if the Button was pressed TWICE in a short time: - Work 1, Cycle 1 - Work 1, Cycle 2 - Work 1, Cycle 3 - Work 1, Cycle 4 - Work 1, Cycle 5 Work 1 ended. - Work 1, Cycle 1 - Work 1, Cycle 2 - Work 1, Cycle 3 - Work 1, Cycle 4 - Work 1, Cycle 5 Work 1 ended. While the procedure is busy, the the form does not show any reaction, but the second click was put into the message queue by Windows. Right after the OnClick has finished it will be called again. INCLUDING ProcessMessages, the output might be very different: - Work 1, Cycle 1 - Work 1, Cycle 2 - Work 1, Cycle 3 - Work 2, Cycle 1 - Work 2, Cycle 2 - Work 2, Cycle 3 - Work 2, Cycle 4 - Work 2, Cycle 5 Work 2 ended. - Work 1, Cycle 4 - Work 1, Cycle 5 Work 1 ended. This time the form seems to be working again and accepts any user interaction. So the button is pressed half way during your first worker function AGAIN, which will be handled instantly. All incoming events are handled like any other function call. In theory, during every call to ProgressMessages ANY amount of clicks and user messages might happen in place. So be careful with your code! Different example (in simple pseudo-code!): procedure OnClickFileWrite() ; var myfile : TFileStream; begin   Ã‚  myfile : TFileStream.create(myOutput.txt) ;   Ã‚  try   Ã‚  Ã‚  Ã‚  while BytesReady 0 do   Ã‚  Ã‚  Ã‚  begin   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  myfile.Write(DataBlock) ;   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  dec(BytesReady,sizeof(DataBlock)) ;   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  DataBlock[2] : #13; {test line 1}   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Application.ProcessMessages;   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  DataBlock[2] : #13; {test line 2}   Ã‚  Ã‚  Ã‚  end;   Ã‚  finally   Ã‚  Ã‚  Ã‚  myfile.free;   Ã‚  end; end; This function writes a large amount of data and tries to unlock the application by using ProcessMessages each time a block of data is written. If the user clicks on the button again, the same code will be executed while the file is still being written to. So the file cannot be opened a 2nd time and the procedure fails. Maybe your application will do some error recovery like freeing the buffers. As a possible result Datablock will be freed and the first code will suddenly raise an Access Violation when it accesses it. In this case: test line 1 will work, test line 2 will crash. The better way: To make it easy you could set the whole Form enabled : false, which blocks all user input, but does NOT show this to the user (all Buttons are not grayed). A better way would be to set all buttons to disabled, but this might be complex if you want to keep one Cancel button for example. Also you need to go through all the components to disable them and when they are enabled again, you need to check if there should be some remaining in the disabled state. You could disable a container child controls when the Enabled property changes. As the class name TNotifyEvent suggests, it should only be used for short term reactions to the event. For time consuming code the best way is IMHO to put all the slow code into an own Thread. Regarding the problems with PrecessMessages and/or the enabling and disabling of components, the usage of a second thread seems to be not too complicated at all. Remember that even simple and fast lines of code might hang for seconds, e.g. opening a file on a disc drive might have to wait until the drive spin up has finished. It doesnt look very good if your application seem to crash because the drive is too slow. Thats it. The next time you add Application.ProcessMessages, think twice ;)

Free sample - Discussions on Psychological Theory. translation missing

Discussions on Psychological Theory. Discussions on Psychological TheoryPresent paper deals with the discussions of the psychological theory and its main principles. According to this theory, usage of drugs and people’s addiction to them can be explained by different factors. The first case under discussion is usage of drugs because of two main factors contributing it. They are reinforcement and personal problems. I completely agree that the positive reinforcement is one of the key factors, making people use drugs. Pleasurable sensations, accruing after drug usage is the main reason of the desire to get drugs again and again. That is why, all people who are addicted to drugs, explain their addiction by this reason. The next motivation for the drug abuse is problems in the emotional life. When people have certain emotional or personal troubles, such as problems in family or relationships, they suppose that drugs are the only way out that can help them to escape from reality. The next point under discussion is drug addiction due to the inadequate personality. People, having the features of the inadequate personality experience low self-respect and feel constant failure of life. As a result they are more apt to become addicted to drugs. I can not agree more with this fact, as in our life there are quite many examples when individuals who are not satisfied with their life try to change this situation with the help of drugs. They think that only under the influence of drugs they can feel more self-confident and successful. The final topic of drug abuse reasons is unawareness of people about the negative effects of such addicting and absence of will power. In this case, the factor of negative reinforcement occurs. Very often, people, suffering from unbearable pains start using drugs in order to decrease pain and unpleasant feelings. They do it without complete understanding of the results, as the only motivation for them is pain relief. Weak will power or its complete absence is very significant factor that should be mentioned. People who are lack of will power have more chances to get into drug dependence. For such people it is very difficult to resist the temptation of drug usage, especially when they are influenced by the friends who are already abused by drugs.

Introduction to ICD Classification - Classification Systems (U2IP&DB) Essay

Introduction to ICD Classification - Classification Systems (U2IP&DB) - Essay Example e United States official system for assigning codes to procedures and diagnoses based on the World Health Organizations Ninth Revision, International Classification of Diseases (ICD-9)† (MediLexicon, 2008, pg. 1). Four main steps are involved in the process of selecting the proper ICD-9-CM codes. These must be followed in detail in order to ensure that the diagnosis is accurately described by the code. The steps described in the following paragraph are necessary in order to establish the proper ICD-9-CM code (Pelaia, 2003, pg. 7). The first step in assigning the proper ICD-9-CM code is to â€Å"review the medical record documentation in order to properly identify the terms that best describe the patient’s diagnosis† (Pelaia, 2003, pg. 8). The second step in assigning the proper code is to â€Å"look up the terms that best describe the patient’s diagnosis in Volume 2 (the alphabetic index) and identify the ICD-9 code that best matches the diagnosis† (Pelaia, 2003, pg. 9). The third step in assigning the proper ICD-9-CM code is to â€Å"look up the selected code in Volume 1 (the tabular list) to make the code selection. Careful attention should be paid to ‘includes’ and ‘excludes’ notes and other instructions in Volume 1† (Pelaia, 2003, pg. 10). Finally, all information should be carefully reviewed and verified. It is extremely important for a medical coder or for a medical professional responsible for ensuring that the correct diagnostic codes are being recorded for the procedures performed at a medical facility is using an up-to-date code book. Failing to use a current code book can result in a variety of mishaps that can easily be avoided. If a person loses his or her current code book, it should be replaced immediately. First of all, it is essential that medical personnel keep proper records in order to stay compliant with legal regulations. Using an old code book could result in the wrong diagnosis being recorded for a patient which could

The Pros and Cons of Crowdsourcing Research Paper

However, a number of corporations or individuals encompass a covert formula that they apply to guarantee constant accomplishment; whereas other people exercise the tried-and-true techniques those have been suggested by the professionals.

Philips Kotler Marketing Management Essay Example for Free

Philips Kotler Marketing Management Essay Analyzing Consumer Markets Since marketing starts from the customer, it is of primary importance to understand the psyche of the customers and their buying motives. This chapter talks about the various behavioural patterns that govern the decision making process of a customer. A marketer needs to understand these factors affecting the customer’s purchase decisions so as to design an appropriate marketing strategy. Factors affecting Consumer Buying Behaviour 1. Cultural Factors a. Culture Frames traditions, values, perceptions, preferences. E.g. Child learning from family surroundings. b. Sub-culture Provides more specific identification and socialization. Include nationalities, religions, racial groups and geographic regions. c. Social Class – Homogeneous and enduring divisions in a society which are hierarchically ordered. Members share similar tastes and behaviour. 2. Social Factors a. Reference Groups – Have direct or indirect influence on person’s attitude and behaviour. Primary groups: regular interaction, e.g. family, friends, neighbours. Secondary groups: religious, professional, trade union groups. Aspirational Groups: ones that a person hopes to join. Dissociative groups: whose values or behaviour and individual rejects. b. Family – Family of orientation: parents and siblings. Acquires orientation towards religion, politics and economics, sense of personal ambition, self worth and love. Family of procreation: spouse and children. More direct influence on buying behaviour. c. Roles and Status – Role consists of activities a person is expected to perform. Each role carries a status. Marketers must be aware of the status symbol of each product. Chapter 6 Analyzing Consumer Markets 3. Personal Factors a. Age and Stage in the Life Cycle – Tastes are age related. Markets should also consider critical life events or transitions. b. Occupation and Economic Circumstances – Economic Circumstances like spendable income, savings, assets, debts, borrowing power etc affect consumption patterns. c. Personality and Self Concept – Personality, set of distinguishing characteristics that influence his/her buying behaviour. Consumers match brand personality with their ideal self concept instead of their actual self concept. d. Lifestyle and Values 4. Psychological Factors a. Motivation: Freud’s theory of id, ego and super ego; Maslow’s need hierarchy theory; Herzberg’s two factor model. b. Perception: Process by which we select, organize and interpret information inputs. In marketing, perceptions are more important than reality. c. Learning – Induces changes in behaviour arising from experience. Marketers can build demand by associating the product with positive drives. d. Memory – Short term and long term memory. Build brand knowledge and brand recall as node in memory. Problem Recogniton Information Search Evaluation of Alternatives Purchase Decision Postpurchase Behaviour The Buying Decision Process Problem Recognition Customer recognises a need triggered by internal or external stimuli. Marketers need to identify circumstances that trigger needs. Information Search Two levels of involvement – Heightened attention when person becomes more receptive to information about the product. At next level consumer may enter into active information search, looking for reading material, phoning friends etc. Evaluation of Alternatives Factors influencing a particular choice over the other include attitudes, beliefs and expectancy value. Purchase Decision Between purchase intention and purchase decision, 2 intervening factors come into play- Attitudes of others and Unanticipated situational factors. Marketers should understand that these factors provoke  risk and should provide information to reduce it. Post purchase Behaviour Marketers must monitor postpurchase satisfaction, postpurchase actions, and postpurchase product uses. Chapter 6 Analyzing Consumer Markets Trends Level of customer involvement Involvement Significant Insignificant Differences in Brands High Complex Buying Behaviour Low Variety Seeking Dissonance Reducing Habitual 1. Complex Buying Behaviour: When a customer purchases something for the first time. 2. Variety Seeking: Consumers will keep switching varieties just out of boredom. Eg- Biscuits. Marketer should keep introducing new products and display the product prominently. 3. Habitual: Buying the same thing out of habit and not out of loyalty. Distribution network should be excellent in this case. Maintain consistency in product and advertising. 4. Dissonance Reducing: In case of repeat purchase of same product.

Plato Essay example -- essays research papers fc

One of the questions that has faced and continues to face some of the philosophers of the world is "What is reality?" Plato addresses this question in his doctrine, the Theory of Forms. In an attempt to answer this question, he explains what the Forms are and how they affect the way the world is observed. These so-called Forms are the basis of the reality we perceive. The question one must ask him or her self is what are these forms, where do they come from, and how do they affect us as a society. "A Platonic Form (Idea) is not a thought in someone's mind but something that exists per se as an immutable part of the structure of reality."(Luce, 99) This statement is the foundation of Plato's philosophy. What he is saying is that these forms are behind the way we see the world. In other words, they control the images and ideas that are presented to us. Two examples of such forms are ideal beauty and absolute goodness. When a person makes a comment like " That is a beautiful home." What is the difference between a beautiful home and a home that is not beautiful? This illustrates the point that Plato is attempting to make about the Forms functioning as a standard by which we compare the world to. In essence, these Forms serve as a measuring stick by which we make our judgements. In regards to the Form of absolute goodness, Plato describes this one as the all- powerful form. Here Plato suggests that the other Forms derive their meaning from the Form of absolute goodness. Some of the other Forms include Equality, circularity, Health and Justice. These forms cannot be seen nor can they be felt; however, they can be apprehended by the mind after suitable preparation and training (Luce, 100). These forms exist in everything we see, in all the decisions we make and it is these Forms that we perceive when we describe something as beautiful or right or even wrong. The Theory of Forms also has two significant underlying doctrines within its contents. The first one is the distinction between opinion and knowledge. One word that Plato uses to describe opinion is flawed. He explains that opinions are always changing due to anything from outside forces or simply just one's perception. For example, the people around can alter a person's opinion or even the type of room someone is in. External pressures are the cause of the variation in opinions ... ...tself (Stump, 62). In the Theory of Forms, Plato provides us with a possible answer to some of the questions that continually plague most people. The answer to the question "What is real" may never have a definitive answer. All one can do is to use the abilities given to him and try to arrive to their own conclusion based on what he or she knows. Whether the reality most of us perceive is true or not is difficult to determine. The Theory of Forms gives us a way of analyzing reality, but like all other doctrines it stops short of precisely defining reality. This inability to conclude the argument is the very same reason why this debate will continue on for as long as we live and probably our children and their children and so on. The pursuit of truth will continue to be the driving force behind the search for the answer to the question that can explain the significance of our existence.

Nutrition Essay

Holozoic nutrition (Gr. holo means-whole ; zoikos means-of animals) is a method of nutrition that involves the ingestion of liquid or solid organic material, digestion, absorption and assimilation of it to utilize it. It includes taking in the complex substances and converting them into simpler forms. Example, proteins can be broken into amino acids. This method suggests phagocytosis where the cell membrane completely surrounds a food particle[pic] Parasitic Nutrition is a mode of heterotrophic nutrition where an organism (known as a parasite) lives on the body surface or inside the body of another type of organism (known as a host). The parasite obtains nutrition directly from the body of the host. Since these parasites derive their nourishment from their host, this symbiotic interaction is often described as harmful to the host. Parasites are dependent on their host for survival, since the host provides nutrition and protection. As a result of this dependence, parasites have considerable modifications to optimise parasitic nutrition and therefore their survival. Saprotrophic nutrition (pron.: /sà ¦prÉ µÃ‹Ë†trÉ’fÉ ªk/) is a process of chemoheterotrophic extracellular digestion involved in the processing of dead or decayed organic matter. It occurs in saprotrophs or heterotrophs, and is most often associated with fungi, for example Mucor and Rhizopus. The process is most often facilitated through the active transport of such materials through endocytosis within the internal mycelium and its constituent hyphae.[1] Autotrophic Nutrition The term autotroph has been derived from two Greek wards-auto means self and troph means nutrition. In this mode of nutrition, the organisms prepare their own food from simple raw materials like water, carbon dioxide and mineral salts in the presence of sunlight. Chlorophylls present in the chloroplast or green plants are the site of food production. Accordingly all green plants are the examples of this category. The process by which they synthesize food is known as photosynthesis. Some nongreen becteria like sulphur bacteria can use energy which they derive from some chemical reactions occurring in them. With this energy they manufacture their food. This process is called chemosynthesis. Thus the autotrophs include both the photosynthetic and che4mosynthetic organisms. Heterotrophic Nutrition The word heterotrophy has been derived from two Greek words-hetero means different and troph refers to nutrition of food. The organisms which derive their food from others are known as heterotrophic organisms. They depend for their food on other organisms, hence they are called consumers. All animals, human beings and non-green plans like fungi come under this category. They consume complex organic food prepared by autotrophs or producers and break it into simple from to derive nourishment. Thus the difference between heterotrophy and autotrophs is basically in the mode of production of food. Due to lack of chlorophyll, heterotrophs cannot synthesize their food while autotrophs can perform photosynthesis.

Evaluating Website

Evaluating a Website for Credibility Rebekah Reed Chamberlain College of Nursing NR500: Foundation Concepts and Applications Fall 2012 Evaluating a Website for Credibility With so many health-related websites on the internet it was hard to choose one. I settled on one that is personal to me and that I do a lot of teaching on with patients. I chose American Diabetes Association at www. diabetes. org. This website is found by searching any of the search engines. This website has both a consumers and professional page. Diabetes is on the rise in the nation and to have a source that has reliable information for patients is a necessity.EVALUATING WEBSITE Evaluating this website for authority was a little cumbersome. The website gives you access to news and research where information on the author and publication is listed. There is a section for communication and discussion boards as well. The majority of information is organized by tabs, ie: living with diabetes, food and fitness, etc. T here is no author on these pages, but you can find information by going to tab about us page. The purpose of this website is to give consumers objective information both education and for entertainment use.The American diabetes association is an associated started in the U. S. to help those affected by diabetes. You as a consumer are able to donate in various ways to help support the research. The website assists you in finding your local chapter and events that are happening in your geographical area. The site provides basic information regarding diabetes and care of the disease. The ease of navigation is very user friendly. I enlisted my twelve year old son and mother who is in her late sixties. I asked each to find the page that gave users information on finger sticks.Both were able to find the information with relative ease. Graphics are loaded quickly and links are functioning. A nice feature I found on this website is the ability to click on an icon that states listen to text and it reads the text to you. This is wonderful for those who have difficulty reading. In addition there are pictures on every page that are related to the topic being discussed for those who learn by visual education. Looking for privacy and security policies shows this website to be certified by Norton Symtec security, Better Business Bureau, Trust wave Trusted Commence and National Health Counsel.You do not have to be a member to get information from this website. You can become a member for no fee and receive information on diet, control and other subjects. Your information is not shared with a third party or placed on a listserv. The privacy policy is easy to understand and find. Empirical Evidence â€Å"This website serves to provide the consumer, as well as the healthcare professional, with information about diabetes, its history, development, treatment and impact on the lives of the diabetic patient. The website homepage makes information available in both English and Spani sh.It is designed to give quick information to the viewer about the latest research and news summaries, a tip of the day, a recipe of the day, personal health risks for diabetes and a link to get local information about diabetes through your zip code. † (Overman, 2006) In this website the section for professionals gives you access to their search engine for any articles in the five main diabetic journals. You also have the option for professional resources which include information for professional education, patient educational information to use and diabetes animation clips to use in presentations.The option for continuing education is provided by both live and online programs through many various links. As a nurse or health care professional you are giving and teaching patients how to manage their disease. You are liable for the information you give that in making sure it is accurate and appropriate. The first decision point in recommending a website is to determine the goa l the website resource will address. For example, a dietitian might refer a patient to a specific recipe website that offers tips and recipes to help the patient become more comfortable preparing low-fat meals.Other specific reasons for referring a patient to a website might be to help the patient 1) learn more about a specific aspect of diabetes; 2) obtain recipes that meet taste preferences, the food budget, and health needs; 3) track activity levels; or 4) receive daily tips on being more successful meeting personal goals. (Evert et al, 2008) Conclusion In conclusion the website www. diabetes. org is a credible health-related website and a source of information for both consumers and professionals.It’s a wealth of knowledge and resources for the consumers in an easy to understand layout and language. For professionals it is a one stop area for up to date information, studies and articles regarding diabetes and related care. References Overman VP; Website Review: American D iabetes Association.

Free Essays on Space Hoax

In July of 1969, the United States launched Apollo 11 from the Kennedy Space Center in Florida. During the 1970’s, many people thought that Neil Armstrong’s landing on the moon was a hoax, only to become one step ahead of the Russians in the â€Å"space race.† I believe that there is evidence that exists to back up the journey that took place. As NASA reported, it took 4 days for Apollo to reach the moon. There are pictures from NASA of the lunar horizon and pictures of the command module that reinforce the trip to the moon. I think that these pictures may be compared to the pictures of today and see that they are not off of a Hollywood set as some people believe. Another piece of evidence that may be used are the footsteps left on the moon in the lunar soil. These impressions will last for millions of years and at the time were used as a study on lunar dust. A third piece of evidence that I would use to prove that Neil Armstrong landed on the moon in 1969 are the moon rocks that he brought back to Earth. I am sure that scientists have run extensive testing on these rocks to show that they were not found on the Earth. This would serve as confirmation to the landing on the moon. Russia, China, East Germany and other cold-war enemies of the USA closely monitored the lunar missions. It was easy to tell whether the Apo llo radio signals were coming from the direction of the Moon, and whether the time delays in conversation matched the distance the signals had to travel. If anything had seemed wrong, surely these unfriendly countries would have loudly shouted to the world that the USA was pulling a hoax! Yet none of them ever questioned NASA's accomplishment. I personally find that they would be the first to argue and to not believe that this mission was complete. Lastly, I believe that it would have been more time consuming to fake the trip to the moon that to arrive there. It would be very challenging to fool scientists...

4 Creative Ways to Advance Your Career

4 Creative Ways to Advance Your Career There’s no worse feeling in the world for a job hunter than finding the perfect position but being eliminated from consideration simply because you fail to meet one requirement. There may be some ways around these â€Å"must-haves,† but in most cases failure to meet the job description - or even one small component of it - can remove you from the running. Instead of taking a chance on it happening again, cover your bases by padding your resume with one or more of these four sought-after skills. 1. Basic CodingWhile a weekend-long program in basic coding won’t land you a job as a software engineer, it will round out your resume. Sites like Codeacademy offer free lessons in a range of programming languages, including PHP, HTML, Python, Javascript, CSS and others. Each lesson is short, powerful, and delivers just what you need to add â€Å"Programming† to the â€Å"Skills† section of your resume.2. Public SpeakingTen percent of people love public spe aking, 10 percent are terrified of it, and the remaining 80 percent are somewhere in the middle - they know it’s not going to be very fun, but they also know they’ll survive the experience.Aside from helping you pass the â€Å"good communication skills† requirement part of a job description requirement, there’s another important reason the majority of people should work on this skill: why would you want a job when you can merely tolerate a major aspect of it? Comfort with public speaking won’t just land you a job; rather, it will continue to be a useful skill throughout your life.Coursera’s â€Å"Introduction to Public Speaking† course is free, always open, and delivers useful instruction and plenty of opportunities for practice through its public speaking curriculum, including a series of videos totaling 18 hours, videos, and peer assessments.3. Graphic DesignGraphic design skills are highly desirable for a wide range of positions, particularly with the growth of social media, digital technology, and ever-popular infographics. While fudging knowledge of Adobe Photoshop, InDesign or Illustrator on your resume can lead to catastrophic results - particularly if you’re called upon to demonstrate your knowledge or experience - it is possible to learn the basics on your own.For example, Adobe offers tutorials designed to help everyone from novices to experts expand their skill set, while online education website Lynda’s â€Å"Photoshop CC Essential Training† offers the training you need to feel comfortable working with Photoshop.4. Website BuildingAn increasing number of employers are requesting that candidates include links to personal websites along with their application materials. Don’t have one of your own? Unfortunately, this may indicate a lack of initiative and/or the inability to keep up with 21st century expectations.Rather than risking coming off as unmotivated, take advantag e of classes aimed at helping beginners acquire the knowledge they need to to build their own websites. The Muse’s â€Å"Your Guide to Building a Personal Website That’ll Land You a Job,† offers the perfect starting point.The best part of many of these web courses and tutorials?

GDP per Capita and Its Challengers - Research Proposal Example First of all, it should be noted that GDP was not designed to evaluate the well-being of a country. Instead, it measures particular types of economic activities within the country, which does not necessarily refer to a standard of living. For one crude example, a country with all goods and services exported will have a high GDP but low well-being of its citizens. Second, GDP takes into account only documented operations. It does include neither black market nor non-monetary operations, like bartering, showing inaccurate information for countries where any of these issues plays an important role. Moreover, some companies commit a cross-border trade within themselves in order to escape high taxation - this distorts GDP, creating additional imports/exports data. Third, GDP indicator shows little information for changes in ecology, society, and lifestyle. For instance, ecological damage is treated by GDP as a double growth: at first, it counts natural resources retrieved, and then it counts services used to replenish natural resources, but it would be far better if the disaster had never occurred in the first place. Additionally, the philosophy of GDP shows wars as contributors to the economy, but child upbringing and housework as valueless actions. It ignores volunteer and unpaid work, but instead, GDP counts work that produces no net change or that results from repairing harm (e.g. the healthcare industry, where economic activity increases along with a number of unhealthy population). Fourth, people buy often low-durability goods and make rare purchases of high-durable products, because of their long use. Sometimes it is possible that the monetary value of the items sold in the first case is higher than that in the second case, in which case a higher GDP is simply the result of greater inefficiency and waste. Fifth, since GDP does count financial purchases as investments, then if a nation does not spend, but saves and invests overseas, its GDP will be diminished in comparison to one that spends borrowed money. Therefore, accumulated savings and debt are not taken into account so long as adequate financing continues. Sixth, sometimes different calculations of GDP confuse each other. There are two different types GDP calculation for cross-border comparison: current currency exchange rate, where GDP is calculated by exchange rates prevailing on international currency markets) and purchasing power parity (PPP) exchange rate, where GDP is calculated by PPP of each currency relative to a selected standard.

Qs.2 knowledge is a true opinion comprising of a rational explanation or definition, and it is also a real belief or a sensation. However, belief is the inner state of mind that is directly accessible to the introspection that relates to human behavior. Belief always plays a central role in the theoretical reasoning and involves a practical reasoning. For instance, in pdf.1, in appendix 3, an example of belief is a statement that states, ‘some people tend to have the ability to learn foreign language’. For a person to have knowledge there must exist a sense of truth, justification, and belief, on a basis of believing in them. For example, a knowledge is evident in this article, whereby the truth remains that ‘English is a foreign language to the non-natives’. Qs.3. Teacher’s beliefs play vital roles towards student’s reaction, acceptance, and theories that concern language. Teachers were also once students thus their understanding about teaching often reflects on to students on how they also learn a language.
