National Labour Relations Act Research Proposal

National Labour Relations Act - Research Proposal Example The entire issue of trade unions among employees in civilised states especially in United States of America has raised endless debate among professionals and other critical thinkers and scholars. Despite discussing on the role and the significant of trade unions among employees, scholars have as well researches on the factors that led to the formation and development of trade unions in United States of America and other developed and developing countries. The subsequent essay will therefore explore and analyse on the importance of trade unions in United States of America and other developed countries. The essay will as well provide a comprehensive research proposal that will seek to train employees and employers on the content the national labour relations act The labour unions are often recognised organisations and movements that are comprised of workers hailing from single industry, employed by a particular business and performing a single job to a specific profit making and non-pr ofit making organization. Some of these unions are instrumental in granting employees a bargaining power to negotiate and agree on better and favourable terms and conditions of employment and remuneration. Compared to individual negotiation between an employee and employer, trade unions give employees and lower class organisation workers more agitation power and influence over their employers. The issue of forming, managing, and joining trade unions in United States have raised continuous debates among stakeholders from varying professional background Problem Statement It is the right of employees to become affiliates and active members of specific trade unions to voice their concerns, grievances, and front their interest and demands to their employees. Similarly, NLRA prohibits employers and managers from either suspending or dismissing their workers because of joining trade unions or because workers have engaged in trade unions strikes and demonstrations. During the epoch of the e conomic depression in United States of America, employers could recruit workers easily while employees found it difficult and challenging to secure another employment. Most workers were as a result less attentive and less interested in forming and in participating in unions’ strikes resulting to less than 10% of people becoming trade unions members by 1933. On the other hand, the NLRA provided the workers the rights and power of becoming members of trade unions thus enabling them to have a collective bargaining power with their bosses through preferred unions’ representatives. As a result, the United States of America constitution and the NLRA Act protected workers from exploitation or mistreatment by their employers. The introduction of NLRA therefore resulted in tremendous growth and development of trade unions membership in America and other developed countries such as United Kingdom (Sloane & Witney, 2010). Literature Review The NLRA Act offers and guarantee worker s protection and right to form, join, and become members of labour unions in order to collectively bargain on matters regarding their working hours, wages, as well as working conditions. Trade unions as well offers avenue for negotiation and interaction between employers and employees. NLRA further prohibits employers from taking punitive and strick actions or measures against employees who wish to become and participate

How the European Economy Works and How This Integration Can Be Affecte Coursework - 1

How the European Economy Works and How This Integration Can Be Affected by the Recession - Coursework Example The European Union is undoubtedly one of the most flourishing business regions in the world with rich countries such as France, Germany, Italy, and Great Britain. The efforts to build the integration in 25 years have paid off with a formidable team such as the European Union.   However, due to increasing global linkages, such as through bilateral and multilateral agreements, it became inevitable that the region is dragged by the recession in other countries such as what happened in the USA. The financial crisis that happened in the United States has affected a lot of its close partners such as Mexico. The European Union is one of those regions with a partnership with the US. Aside from this, the region’s economy has also some of its weaknesses. This, together with the global financial crisis that started from the US has become a threat to the region.In this paper, there is an attempt to analyze the effect of the global recession on the European Union and its member countries . First, we conduct a short study on what the integration has achieved so far in 25 years, then we look at the current figures to see the effect of the recession and lastly we analyze what this means for the future of the European Union, with a particular focus on the European business environment.Efforts to foster unity and integration between and among the European countries began in 1949, after the Second World War, when West Europe created the Council in Europe, although at this time the continent is still split between East and West   (European Commission).  Ã‚   The integration began with six European nations: Germany, France, Italy, the Netherlands, Belgium, and Luxembourg when the Coal and Steel Treaty was signed, then expanding to nine in 1973 with the addition of Denmark, United Kingdom and Ireland   (European Commission). It took around 20 years before the expansion took place. Prior to the expansion, plans of having a single currency among the EU states was already coined,   but was only formally introduced in 2002, distributing them in 12 member countries   (European Commission). Currently, the member states of the EU number to up to around 27, with the addition of some countries like Spain, Finland and Greece.

Calculating Free Fall Acceleration

Calculating Free Fall Acceleration Introduction A research by Heckert (2010) shows in 1600s, the famous physicist Galileo . Galilei found the swinging motion of a large chandelier in the Pisa cathedral. He began to seriously analyse the chandelier, and recorded the time the light took to swing. In the 16th century, there was no stopwatch so that Galileo timed the swing by pulse. In addition, he was the first European to really study this phenomenon and he discovered that their regularity could be used for calculate the local gravity. For Galileo his pendulum was the light but generally speaking a pendulum can be defined as a body suspended from a fixed point which swing freely by the motion of gravity and momentum. It is used to regulate the movements of clockwork and other machinery. In its simplest form and avoiding the math there are three parts to the basic laws of a pendulum. First the time for each oscillation is depending on the length of the strings. In addition, mass of the bob does not affect the motion at all. Second, a pendulums horizontal speed is the same as the vertical speed would be, if the bob had fallen from its highest point. Thirdly, the square of period of the bob is inversely proportional to free fall acceleration and the square of period of the body is proportional to length of the pendulum The background definition and the laws of a pendulum can be used to calculate the free fall acceleration. Using a simple gravity pendulum like Galileos Pendulum System, I would like to show how to find the best ways in order to test free fall acceleration. Methods 1. Experiment equipment: Protractor Steel Bob Stopwatch Vernier Caliper Iron Support Stand Meter Ruler Inelastic String 2. Apparatus setup Figure1-1 Figure1-1 shows that iron support stand was put beside edge of test desk in case the height of stand was shorter than the length of test string. Next, the steel ball was hung by an inelastic string and the iron support stand was used to support the weight of steel ball. Last, the clip was clamped to the string in order to keep a constant length. At the same time, the bob swing in a vertical surface which parallels the stand. 3. Procedures First of all, the simple pendulum was made up by hanging a bob from the top of stand and the bob was released in a constant height, then protractor was used to control the degree between 5 and 15 to normal line. Secondly, pendulum would begin to oscillate in vertical surface in a regular action, and then the stop watch was used to record the time of each swing. Finally the most important data which describes this oscillation is period and we did different types of test by different length of string, like 30cm, 45 cm, 60 cm, 75 cm, 90cm, 105 cm, and 120 cm. Results Table of result Experiment times Length of string (cm) Trials: 1 Trials: 2 Total Average period Oscillationtimes Average period of each swing T2 (second square) Time taken for one complete Oscillation(seconds) 1 30cm 56.60s 56.50s 56.55s 50 times 1.13s 1.28s2 2 45 cm 68.60s 68.50s 68.55s 50 times 1.37s 1.88 s2 3 60 cm 79.00s 78.90s 79.00s 50 times 1.58s 2.50 s2 4 75 cm 87.60s 87.90s 87.75s 50 times 1.76s 3.08 s2 5 90 cm 96.05s 96.00s 96.05s 50 times 1.92s 3.69 s2 6 105 cm 104.00s 104.00s 104.00s 50 times 2.08s 4.33 s2 7 120 cm 110.50s 111.00s 110.75s 50 times 2.22s 4.91 s2 Table-1.1 Table-1.1 shows the data of 7 experiments using different length of string and how the data changed, as the length of string was increased; the period of each oscillation was increase as well. L is the distance from the frame of the stand to the center of the mass; the length includes the radius of ball. The period of oscillation is the time required for the pendulum to complete one swing. For one complete swing, the steel ball must move from the left to the right and back to the left. T2 can be understood as the square of the period of oscillation, the equation below shows how T2 was calculated. Square both sides: T2= 4 Ãâ€" Ï€2 Ãâ€" (L/g) T2 = L Ãâ€" (4 Ãâ€" Ï€2 à · g) Multiply both sides by g g Ãâ€" T2 = 4 Ãâ€" Ï€2 Ãâ€" L Divide both sides by T2 Discussion and Analysis The results of experiment show the relation between T2 and length of string. To turn to discuss the results it is important to understand some key ideas, there are controlled variable, experimental variable, error and uncertainty. Firstly, according to Science Buddies(2009) said that a controlled variable can be defined as the factor which is unchanged or kept constant to prevent its effects or error on the outcome. It was verified the behavior of the relationship between independent and dependent variables. The factors which can be regarded as controlled variable were steel ball, oscillation times; the angle of each swing and the height when the steel ball was released. An answer from wiki (2009) the definition of experimental variables is the variable whose values are independent of changes in the values of other variables. Experimental variable in this experiment is the length of string. According to dictionary the error can be defined as a deviation from accuracy or correctness. And the uncertainty means that the lack of certainty, a state of having limited knowledge so that it is impossible to exactly describe existing phenomenon or future outcome confidently.Errors were caused by any individual who could be affected by many factors. Such as before we measure the length of string, we need to measure the radius of ball by vernier caliper in case the string is shorter than actual length. Secondly, we need to take care of how much oscillation times we did. Thirdly, we need to keep the pendulum swing in a same surface in case the extra energy was wasted. At last, taking more time measurements of experimental variable which is length of string may be more accurate average for each trial. Find two point from the graph A(x1, y1) B(x2, y2), use the formula (y2-y1)/(x2-x1) the result of gradient is 4.03. The table shows the results of free fall acceleration Gradient(T2/L) 4.03 Calculate data in using formula G 9.79ms-2 Confines of Error 0.22% Table2-1 To summarize the weakness that is error and uncertainty and calculating the acceleration of gravity to within 5%, and table 2-1 shows that the experiment obeys the allowable confines. Confines of Error were calculated by the difference between actual gravity and what I got, and the values were divided by the actual values. Conclusion To sum up, the calculation of Galileo that free fall acceleration from the formula, this can infer the result of free fall acceleration. I need to compare the calculation of Galileo which free fall acceleration should be 9.81ms-2. In fact, a gravity pendulum is a complex machine, depending on a number of variables for which we are ready to adjust. In addition, firstly we try to understand the method that Galileo did in 1600s, and making a plan to have a complete the system. Then form the data I found some different values about gravity, and the factor to influence the values. The main factor is that the different length of string influence the period instead free fall acceleration, the period square and length have a constant ratio to calculated the acceleration. Turning to Dohrman, P (2009) it can be argued that the factors which influence the fact are length of the string, period of each cycle by using those two factors we can get the local gravity. All above those factors can influence the values of free fall acceleration, and we got the less number than actual values. I need to take care of them and have an improvement. For instance, first difficulty is that measuring the length is deciding where the centre of the bob is. The uncertainty in determining this measurement is probably about 1 mm. Secondly, the stopwatch measures to 50 of oscillation although the overall accuracy of the time measurements may be not certain. According toDohrman (2009) the human reaction time to start and stop the watch has a maximum range of 0.13 seconds and the average is0.7. Finally, 9.79ms-2 was calculated by the gradient and the formula in part of result.

America Needs Capital Punishment Essay -- Pro Death Penalty Essays

In this essay, I will argue for the implementation of the death penalty. I will establish a clear-cut profile for a criminal to be eligible for death row. I will put forth arguments for and against the death penalty as supported by various groups and try to defend my position. I shall also try to criticize the case against the death penalty with individual arguments. Finally, I will demonstrate that no alternative to capital punishment can be reached and try to convince you for its fairness. Despite ethical and moral concerns, the issue of capital punishment must not be dismissed without serious consideration and scrutiny.   Ã‚  Ã‚  Ã‚  Ã‚  Is our judiciary system working the way it is suppose to? Many people and countries are convinced that the judiciary system of the United States is a joke. While law may be rigid and defined, there are a number of loopholes which allow criminals to be set free into the streets. One such loophole has the death penalty in its eyes. In my opinion, criminals who commit a heinous crime should be put on death row and they should be executed as soon as possible without having the slights chance to end back up in society.   Ã‚  Ã‚  Ã‚  Ã‚  What type of criminals would meet the criteria for death row? Should every lawbreaker, from a thief to murderer, be sentenced to such a harsh punishment? Absolutely not. In fact, I propose that it is the very extreme felons that should face this penalty. Murderers are the only ones that should be sentenced to death. As a matter of fact, I believe, it is only mass murderers that should confront this penalty. While murder is inexcusable, there are a number of ways in which a guilty party might not have been in full control nor done so with a different intent. Crimes of passion, for example is one such case where one may be compelled to murder, drunk driving and other driving accidents that cause fatalities. Another example could be seen in cases of revenge, such as killing a rapist. Where as such murderers should be punished accordingly, they do not deserve a death penalty.   Ã‚  Ã‚  Ã‚  Ã‚  On the other hand, planed violence geared toward a group of induvilas rather than a single person must be penalized. Most murders that are seen today come on the mass scale. News reports are full of stories such as the â€Å"Oklahoma City Bomber†, who killed over one hundred people by bombs. One more recent story was the â€Å"Sniper† story, wher... ...le this system is very good for a single murder and should be implemented, it falls through in the case of multiple murders. Thus so far there are no alternatives to the death penalty.   Ã‚  Ã‚  Ã‚  Ã‚  The only reasonable excuse against the death penalty is the execution of an innocent person. None the less, while in the past Techniques such as DNA testing did not exist, frequently police agencies are more precise in their accusation as well as their methods of finding the guilty party. As a society we must grant our trust into the hands of authority. While there still can be wrong imprisonment of people for petty crimes such as robbery, these would not quality for the death row. On the other hand, those people who committed mass murder, and let me reiterate mass murderers are often not wrongfully accused. These people deserve no less for themselves than what they have done to others. Even though we are compelled to remember a famous saying â€Å"An Eye For An Eye Makes The World Go Blind† we should not forget that death penalty, as I believe, should be applied to murderers of multiple victims. In this sense let’s rephrase the saying accordingly â €Å"50 eyes for an eye make’s reasonable sense.† America Needs Capital Punishment Essay -- Pro Death Penalty Essays In this essay, I will argue for the implementation of the death penalty.

Ethnic Minority Adolescents Essay

Define and give two examples of diversity as a dimension of ethnic minority adolescents One important dimension of ethnic minority adolescents is their diversity. It is highly evident that ethnic minorities are different in terms of their historical background, economic experiences, and social qualities (Santrock, 2007). They may also have different traditions, beliefs, and practices, among others. However, even though these ethnic minority groups have legitimate differences from other people, they should not be considered as inferior beings entirely as they are still human being just like the people who often discriminate against them. In other words, instead of criticizing or belittling the differences, one should acknowledge, accept, and most of all, respect their differences as this allows one to get along with them in a society that is filled and multiply and vast cultures and ethnicities. Acknowledging and respecting their difference would also mean putting oneself in their shoes and thinking about how would they feel. One example of diversity as a dimension of ethnic minority is their different customs and traditions. For example, a Mexican-American adolescent’s way of praying should not be ridiculed but instead be respected most especially if does not affect or impact the normal lives of other people. This also includes his or her food preferences and clothes, among many others. Another example is when an Asian-American boy is expected to be fluent in Chinese even though he was born and raised in the United States. This is a case of stereotyping as the boy, even though he has Chinese roots, has assimilated into the American culture and is not familiar with the language of his heritage. In short, people should keep an open mind when dealing with different ethnic minority adolescents. They should always apply a multicultural perspective and embrace the fact that one of the distinguishing aspects of these groups is their diversity. By doing so, these ethnic minority adolescents would grow up having an easier time associating with people from other ethnic groups. References Santrock, J. W. (2007). Adolescence.

Crowdsourcing: Human-based Computation and Amazon Mechanical Turk

In a companion blog post to his June 2006 Wired magazine article, Jeff Howe posited the first definition of crowdsourcing:â€Å"Simply defined, crowdsourcing represents the act of a company or institution taking a function once performed by employees and outsourcing it to an undefined (and generally large) network of people in the form of an open call. This can take the form of peer-production (when the job is performed collaboratively), but is also often undertaken by sole individuals. The crucial prerequisite is the use of the open call format and the large network of potential laborers.†Daren C. Brabham was the first to define â€Å"crowdsourcing† in the scientific literature in a February 1, 2008, article:â€Å"Crowdsourcing is an online, distributed problem-solving and production model.†In the classic use of the term, problems are broadcast to an unknown group of solvers in the form of an open call for solutions. Users—also known as the crowd—s ubmit solutions which are then owned by the entity that broadcasted the problem—the crowdsourcer. In some cases, the contributor of the solution is compensated monetarily, with prizes, or with recognition. In other cases, the only rewards may be kudos or intellectual satisfaction. Crowdsourcing may produce solutions from amateurs or volunteers working in their spare time, or from experts or small businesses which were unknown to the initiating organization.Crowdsourcers are primarily motivated by its benefits. One of these includes the ability to gather large numbers of solutions and information at a relatively inexpensive cost. Users are motivated to contribute to crowdsourced tasks by both intrinsic motivations, such as social contact,  intellectual stimulation, and passing time, and by extrinsic motivations, such as financial gain.Due to the blurred limits of crowdsourcing, many collaborative activities are considered crowdsourcing even when they are not. Another consequ ence of this situation is the proliferation of definitions in the scientific literature. Different authors give different definitions of crowdsourcing according to their specialties, losing in this way the global picture of the term.After studying more than 40 definitions of crowdsourcing in the scientific and popular literature, Enrique Estellà ©s-Arolas and Fernando Gonzà ¡lez Ladrà ³n-de-Guevara developed a new integrating definition:â€Å"Crowdsourcing is a type of participative online activity in which an individual, an institution, a non-profit organization, or company proposes to a group of individuals of varying knowledge, heterogeneity, and number, via a flexible open call, the voluntary undertaking of a task. The undertaking of the task, of variable complexity and modularity, and in which the crowd should participate bringing their work, money, knowledge and/or experience, always entails mutual benefit. The user will receive the satisfaction of a given type of need, be it economic, social recognition, self-esteem, or the development of individual skills, while the crowdsourcer will obtain and utilize to their advantage that what the user has brought to the venture, whose form will depend on the type of activity undertaken†.Henk van Ess emphasizes the need to â€Å"give back† the crowdsourced results to the public on ethical grounds. His non-scientific, non-commercial definition is widely cited in the popular press:â€Å"Crowdsourcing is channeling the experts’ desire to solve a problem and then freely sharing the answer with everyone†Crowdsourcing systems are used to accomplish a variety of tasks. For example, the crowd may be invited to develop a new technology, carry out a design task (also known as community-based design or distributed participatory  design), refine or carry out the steps of an algorithm (see human-based computation), or help capture, systematize, or analyze large amounts of data (see also citizen science).HistoryThe term â€Å"crowdsourcing† is a portmanteau of â€Å"crowd† and â€Å"outsourcing,† coined by Jeff Howe in a June 2006 Wired magazine article â€Å"The Rise of Crowdsourcing†. It has been argued that crowdsourcing can only exist on the Internet and is thus a relatively recent phenomenon., however, long before modern crowdsourcing systems were developed, there were a number of notable examples of projects that utilized distributed people to help accomplish tasks.Historical examples The Oxford English DictionaryThe Oxford English Dictionary (OED) may provide one of the earliest examples of crowdsourcing. An open call was made to the community for contributions by volunteers to index all words in the English language and example quotations of their usages for each one. They received over 6 million submissions over a period of 70 years. The making of the OED is detailed in The Surgeon of Crow Thorne by Simon Winchester.Crowdsourcing in gene alogy researchGenealogical research was using crowdsourcing techniques long before computers were common. Beginning in 1942 members of The Church of Jesus Christ of Latter-Day Saints (also known as the Mormon church) encouraged members to submit information about their ancestors. The submitted information was gathered together into a single collection. In 1969 in order to encourage more people to participate in gathering genealogical information about their ancestors, the church started the three-generation program. In this program church members were asked to prepare documented family group record forms for the first three generations. The program was later expanded to encourage members to research at least 4 generations, and became known as the four-generation program.Institutes that have records of interest to genealogical research have used crowds of volunteers to create catalogs and indexes to records.Early crowdsourcing competitionsCrowdsourcing has often been used in the past as a competition in order to discover a solution. The French government proposed several of these competitions, often rewarded with Montyon Prizes, created for poor Frenchmen who had done virtuous acts. These included the Leblanc process, or the Alkali Prize, where a reward was provided for separating the salt from the alkali, and the Fourneyron's Turbine, when the first hydraulic commercial turbine was developed.In response to a challenge from the French government, Nicholas Appert won a prize for inventing a new way of food preservation that involved sealing food in air-tight jars. The British government provided a similar reward to find an easy way to determine a ship’s longitude in the The Longitude Prize. During the Great Depression, out-of-work clerks tabulated higher mathematical functions in the Mathematical Tables Project as an outreach project.Modern methodsToday, crowdsourcing has transferred mainly to the Internet. The Internet provides a particularly good venue for crowdsourcing since individuals tend to be more open in web-based projects where they are not being physically judged or scrutinized and thus can feel more comfortable sharing. This ultimately allows for well-designed artistic projects because individuals are less conscious, or maybe even less aware, of scrutiny towards their work. In an online atmosphere more attention is given to the project rather than communication with other individuals.Crowdsourcing can either take an explicit or an implicit route. Explicit crowdsourcing lets users work together to evaluate, share, and build different specific tasks, while implicit crowdsourcing means that users solve a problem as a side effect of something else they are doing.With explicit crowdsourcing, users can evaluate particular items like books or webpages, or share by posting products or items. Users can also build artifacts by providing information and editing other people's work.Implicit crowdsourcing can take two forms: standalo ne and piggyback. Standalone allows people to solve problems as a side effect of the task they are actually doing, whereas piggyback takes users' information from a third-party website to gather information.Types of crowdsourcingIn coining the term of â€Å"crowdsourcing†, Jeff Howe has also indicated some common categories of crowdsourcing that can be used effectively in the commercial world. Some of these web-based crowdsourcing efforts include crowdvoting, wisdom of the crowd, crowdfunding, microwork, creative crowdsourcing and inducement prize contests. Although these may not be an exhaustive list, they cover the current major ways in which people use crowds to perform tasks.According to definition by Henk van Ess that has been widely cited in the popular press,â€Å"The crowdsourced problem can be huge (epic tasks like finding alien life or mapping earthquake zones) or very small (‘where can I skate safely?'). Some examples of successful crowdsourcing themes are p roblems that bug people, things that make people feel good about themselves, projects that tap into niche knowledge of proud experts, subjects that people find sympathetic or any form of injustice.†Crowd votingCrowd voting occurs when a website gathers a large group's opinions and judgment on a certain topic. The Iowa Electronic Market is a prediction market that gathers crowds' views on politics and tries to ensure accuracy by having participants pay money to buy and sell contracts based on political outcomes.Threadless.com selects the t-shirts it sells by having users provide designs and vote on the ones they like, which are then printed and available for purchase. Despite the small nature of the company, thousands of members provide designs and vote on them, making the website’s products truly created and selected by the crowd, rather than the company. Some of the most famous examples have made use of social media channels: Domino's Pizza, Coca Cola, Heineken and Sam Adams have thus crowdsourced a new pizza, song, bottle design or beer, respectively.Crowdsourcing creative workCreative crowdsourcing spans sourcing creative projects such as graphic design, architecture, apparel design, writing, illustration. etc. Some of the better known creative domains that use the Crowdsourcing model include 99designs, DesignCrowd, crowdspring, Jade Magnet, Threadless, Poptent, GeniusRocket and TongalCrowdfundingCrowdfunding is the process of funding your projects by a multitude of people contributing a small amount in order to attain a certain monetary goal. Goals may be for donations or for equity in a project. The dilemma right now for equity crowdfunding in the USA is how the SEC is going to regulate the entire process. As it stands rules and regulations are being refined by the SEC and they will have until Jan. 1st, 2013 to tweak the fundraising methods. The regulators are on edge because they are already overwhelmed trying to regulate Dodd – Frank and all the other rules and regulations involving public companies and the way they trade. Advocates of regulation claim that crowdfunding will open up the flood gates for fraud, have called it the â€Å"wild west† of fundraising, and have compared it to the 1980s days of penny stock â€Å"cold-call cowboys.†The process allows for up to 1 million dollars to be raised without a lot of the regulations being involved. Companies under the current proposal will have a lot of exemptions available and be able to raise capital from a larger pool of persons which can include a lot lower thresholds for investor criteria whereas the old rules required that the person be an â€Å"accredited† investor. These people are often recruited from social networks, where the funds can be acquired from an  equity purchase, loan, donation, or pre-ordering. The amounts collected have become quite high, with requests that are over a million dollars for software like Trampoline Systems , which used it to finance the commercialization of their new software.A well-known crowdfunding tool is Kickstarter, which is the biggest website for funding creative projects. It has raised over $100 million, despite its all-or-nothing model which requires one to reach the proposed monetary goal in order to acquire the money. UInvest is another example of a crowdfunding platform that was started in Kiev, Ukraine in 2007. Crowdrise brings together volunteers to fundraise in an online environment.Most recently, the adult industry gained its own site in the way of Offbeatr. Offbeatr allows the community to cast votes on projects they would like to see make it to the funding phase. â€Å"Wisdom of the crowd†Wisdom of the crowd is another type of crowdsourcing that collects large amounts of information and aggregates them to gain a complete and accurate picture of a topic, based on the idea that a group of people is on average more intelligent than an individual. This idea of co llective intelligence proves particularly effective on the web because people from diverse backgrounds can contribute in real-time within the same forums.iStockPhoto provides a platform for people to upload photos and purchase them for low prices. Clients can purchase photos through credits, giving photographers a small profit. Again, the photo collection is determined by the crowd's voice for very low prices.In February 2012, a stock picking game called Ticker Picker Pro was launched, using crowdsourcing to create a hedge fund that would buy and sell stocks based on the ideas coming out of the game. These crowdsourced ideas, coming from so many people, could help one pick the best stocks based on this idea that collective ideas are better than individual ones.MicroworkMicrowork is a crowdsourcing platform where users do small tasks for which computers lack aptitude for low amounts of money. Amazon’s popular Mechanical Turk has created many different projects for users to par ticipate in, where each task requires very little time and offers a very small amount in payment. The Chinese versions of this, commonly called Witkey, are similar and include such sites as Taskcn.com and k68.cn. When choosing tasks, since only certain users â€Å"win†, users learn to submit later and pick less popular tasks in order to increase the likelihood of getting their work chosen. An example of a Mechanical Turk project is when users searched satellite images for images of a boat in order to find lost researcher Jim Gray. Inducement prize contestsWeb-based idea competitions, or inducement prize contests often consist of generic ideas, cash prizes, and an Internet-based platform to facilitate easy idea generation and discussion. An example of these competitions includes an event like IBM’s 2006 â€Å"Innovation Jam†, attended by over 140,000 international participants and yielding around 46,000 ideas. Another example is Netflix Prize in 2009. The idea wa s to ask crowd to come up with a recommendation algorithm which was more accurate than Netflix's own algorithm. It had a grand prize of US$1,000,000 and it was given to the BellKor's Pragmatic Chaos team which bested Netflix's own algorithm for predicting ratings by 10.06%Another example of competition-based crowdsourcing is the 2009 DARPA experiment, where DARPA placed 10 balloon markers across the United States and challenged teams to compete to be the first to report the location of all the balloons. A collaboration of efforts was required to complete the challenge quickly and in addition to the competitive motivation of the contest as a whole, the winning team (MIT, in less than nine hours) established its own â€Å"collaborapetitive† environment to generate participation in their team. A similar challenge was the Tag Challenge, funded by the US State Department, which required locating and photographing individuals in 5 cities in the US and Europe within 12 hours based o nly on a single photograph. The winning team managed to locate 3 suspects by mobilizing volunteers world-wide using a similar incentive scheme to the one  used in the Balloon Challenge.Open innovation platforms are a very effective way of crowdsourcing people’s thoughts and ideas to do research and development. The company InnoCentive is a crowdsourcing platform for corporate research and development where difficult scientific problems are posted for crowds of solvers to discover the answer and win a cash prize, which can range from $10,000 to $100,000 per challenge. InnoCentive, of Waltham, MA and London, England is the leader in providing access to millions of scientific and technical experts from around the world. The company has provided expert crowdsourcing to international Fortune 1000 companies in the US and Europe as well as government agencies and nonprofits.The company claims a success rate of 50% in providing successful solutions to previously unsolved scientific and technical problems. IdeaConnection.com challenges people to come up with new inventions and innovations and Ninesigma.com connects clients with experts in various fields. The X PRIZE Foundation creates and runs incentive competitions where one can win between $1 million and $30 million for solving challenges. Local Motors is another example of crowdsourcing. A community of 20,000 automotive engineers, designers and enthusiasts competes to build offroad rally trucks. Implicit crowdsourcingImplicit crowdsourcing is less obvious because users do not necessarily know they are contributing, yet can still be very effective in completing certain tasks. Rather than users actively participating in solving a problem or providing information, implicit crowdsourcing involves users doing another task entirely where a third party gains information for another topic based on the user’s actions.A good example of implicit crowdsourcing is the ESP game, where users guess what images are a nd then these labels are used to tag Google images. Another popular use of implicit crowdsourcing is through reCAPTCHA, which asks people to solve Captchas in order to prove they are human, and then provides Captchas from old books that cannot be deciphered by computers in order to try and digitize them for the web. Like Mechanical Turk, this task is simple for humans but would be incredibly difficult for computers.Piggyback crowdsourcing can be seen most frequently by websites such as Google that mine one’s search history and websites in order to discover keywords for ads, spelling corrections, and finding synonyms. In this way, users are unintentionally helping to modify existing systems, such as Google’s ad words.CrowdsourcersThere are a number of motivations for businesses to use crowdsourcing to accomplish tasks, find solutions for problems, or to gather information. These include the ability to offload peak demand, access cheap labor and information, generate bet ter results, access a wider array of talent than might be present in one organization, and undertake problems that would have been too difficult to solve internally. Crowdsourcing allows businesses to submit problems on which contributors can work, such as problems in science, manufacturing, biotech, and medicine, with monetary rewards for successful solutions. Although it can be difficult to crowdsource complicated tasks, simple work tasks can be crowdsourced cheaply and effectively.Crowdsourcing also has the potential to be a problem-solving mechanism for government and nonprofit use. Urban and transit planning are prime areas for crowdsourcing. One project to test crowdsourcing's public participation process for transit planning in Salt Lake City has been underway from 2008 to 2009, funded by a U.S. Federal Transit Administration grant. Another notable application of crowdsourcing to government problem solving is the Peer to Patent Community Patent Review project for the U.S. Pat ent and Trademark Office.Researchers have used crowdsourcing systems, in particular Mechanical Turk, to aid with research projects by crowdsourcing aspects of the research process such as data collection, parsing, and evaluation. Notable examples include using the crowd to create speech and language databases,and using the crowd to conduct user studies. Crowdsourcing systems provide these researchers with the ability to gather large amount of data. Additionally, using crowdsourcing, researchers can collect data from populations and  demographics they may not have had access to locally, but that improve the validity and value of their work.Artists have also utilized crowdsourcing systems. In his project the Sheep Market, Aaron Koblin used Mechanical Turk to collect 10,000 drawings of sheep from contributors around the world. Sam Brown (artist) leverages the crowd by asking visitors of his website explodingdog to send him sentences that he uses as inspirations for paintings. Art cur ator Andrea Grover argues that individuals tend to be more open in crowdsourced projects because they are not being physically judged or scrutinized. As with other crowdsourcers, artists use crowdsourcing systems to generate and collect data. The crowd also can be used to provide inspiration and to collect financial support for an artist’s work.Additionally, crowdsourcing from 100 million drivers is being used by INRIX to collect users' driving times to provide better GPS routing and real-time traffic updates.DemographicsThe crowd is an umbrella term for people who contribute to crowdsourcing efforts. Though it is sometimes difficult to gather data about the demographics of the crowd, a study by Ross et al. surveyed the demographics of a sample of the more than 400,000 registered crowdworkers using Amazon Mechanical Turk to complete tasks for pay.While a previous study in 2008 by Ipeirotis found that users at that time were primarily American, young, female, and well-educated , with 40% having incomes >$40,000/yr, in 2009 Ross found a very different population. By Nov. 2009, 36% of the surveyed Mechanical Turk workforce was Indian. Of Indian workers were male, and 66% had at least a Bachelor’s degree. ? had annual incomes less than $10,000/yr, with 27% sometimes or always depending on income from Mechanical Turk to make ends meet.The average US user of Mechanical Turk earned $2.30 per hour for tasks in 2009, versus $1.58 for the average Indian worker. While the majority of users worked less than 5 hours per week, 18% worked 15 hours per week or more. This is less than minimum wage in either country, which Ross suggests raises ethical questions for researchers who use crowdsourcing.The demographics of http://microworkers.com/ differ from Mechanical Turk in that the US and India together account for only 25% of workers. 197 countries are represented among users, with Indonesia (18%) and Bangladesh (17%) contributing the largest share. However, 28% o f employers are from the US.Another study of the demographics of the crowd at iStockphoto found a crowd that was largely white, middle- to upper-class, higher educated, worked in a so-called â€Å"white collar job,† and had a high-speed Internet connection at home.Studies have also found that crowds are not simply collections of amateurs or hobbyists. Rather, crowds are often professionally trained in a discipline relevant to a given crowdsourcing task and sometimes hold advanced degrees and many years of experience in the profession.Claiming that crowds are amateurs, rather than professionals, is both factually untrue and may lead to marginalization of crowd labor rights.MotivationsMany scholars of crowdsourcing suggest that there are both intrinsic and extrinsic motivations that cause people to contribute to crowdsourced tasks, and that these factors influence different types of contributors.For example, students and people employed full-time rate Human Capital Advancement as less important than part-time workers do, while women rate Social Contact as more important than men do.Intrinsic motivations are broken down into two categories, enjoyment-based and community-based motivations. Enjoyment-based motivations refer to motivations related to the fun and enjoyment that the contributor experiences through their participation. These motivations include: skill variety, task identity, task autonomy, direct feedback from the job, and pastime. Community-based motivations refer to motivations related to community participation, and include community identification and social contact.Extrinsic motivations are broken down into three categories, immediate payoffs, delayed payoffs, and social motivations. Immediate payoffs, through monetary payment, are the immediately received compensations given to those who complete tasks. Delayed payoffs are benefits that can be used to generate future advantages, such as training skills and being noticed by potential employ ers. Social motivations are the rewards of behaving pro-socially, such as altruistic motivations. Chandler and Kapelner found that US users of the Amazon Mechanical Turk were more likely to complete a task when told they were going to â€Å"help researchers identify tumor cells,† than when they were not told the purpose of their task. However, of those who completed the task, quality of output did not depend on the framing of the task.Another form of social motivation is prestige or status. The International Children's Digital Library recruits volunteers to translate and review books. Because all translators receive public acknowledgment for their contribution, Kaufman and Schulz cite this as a reputation-based strategy to motivate individuals who want to be associated with institutions that have prestige. The Amazon Mechanical Turk uses reputation as a motivator in a different sense, as a form of quality control. Crowdworkers who frequently complete tasks in ways judged to b e inadequate can be denied access to future tasks, providing motivation to produce high-quality work. CriticismsThere are two major categories of criticisms about crowdsourcing, (1) the value and impact of the work received from the crowd and (2) the ethical implications of low wages paid to crowdworkers. Most of these criticisms are directed towards crowdsourcing systems that provide extrinsic monetary rewards to contributors, though some apply more generally to all crowdsourcing systems. Impact of crowdsourcing on product qualitySusceptibility to faulty results caused by targeted, malicious work efforts. Since crowdworkers completing microtasks are paid per task, there is often a financial incentive to complete tasks quickly rather than well. Verifying responses is time consuming, and so requesters often depend on having  multiple workers complete the same task to correct errors. However, having each task completed multiple times increases time and monetary costs.Crowdworkers ar e a nonrandom sample of the population. Many researchers use crowdsourcing in order to quickly and cheaply conduct studies with larger sample sizes than would be otherwise achievable. However, due to low worker pay, participant pools are skewed towards poor users in developing countries.Increased likelihood that a crowdsourced project will fail due to lack of monetary motivation or too few participants. Crowdsourcing markets are not a first-in-first-out queue. Tasks that are not completed quickly may be forgotten, buried by filters and search procedures so that workers do not see them. This results in a long tail power law distribution of completion times. Additionally, low-paying research studies online have higher rates of attrition, with participants not completing the study once started. Even when tasks are completed, crowdsourcing doesn't always produce quality results. When Facebook began its localization program in 2008, it encountered criticism for the low quality of its cro wdsourced translations.One of the problems of crowdsourcing products is the lack of interaction between the crowd and the client. Usually there is little information about the final desired product and there is often very limited interaction with the final client. This can decrease the quality of product as client interaction is a vital part of the design process.It is usually expected from a crowdsourced project to be unbiased by incorporating a large population of participants with a diverse background. However, most of the crowdsourcing works are done by people who are paid or directly benefit from the outcome (e.g. most of open source projects working on Linux). In many other cases, the resulted product is the outcome of a single person's endeavour who creates the majority of the product while the crowd only participates in minor details.Concerns for crowdsourcersEthical concerns. Because crowdworkers are considered independent contractors  rather than employees, they are not guaranteed a minimum wage. In practice, workers using the Amazon Mechanical Turk generally earn less than the minimum wage, even in India. Some researchers considering using Mechanical Turk to get participants for studies have argued that this may be unethical.Below-market wages. The average US user of Mechanical Turk earned $2.30 per hour for tasks in 2009, versus $1.58 for the average Indian worker. While the majority of users worked less than 5 hours per week, 18% worked 15 hours per week or more, and 27% of Indian users said income from Mechanical Turk is sometimes or always necessary for them to make ends meet. This is less than minimum wage in either country, which Ross et al. suggest raises ethical questions for researchers who use crowdsourcing.[ When Facebook began its localization program in 2008, it received criticism for using crowdsourcing to obtain free labor.Typically, no written contracts, non-disclosure agreements, or employee agreements are made with crowdsourced e mployees. For users of the Amazon Mechanical Turk, this means that requestors have final say over whether users’ work is acceptable; if not, they will not be paid. Critics claim that crowdsourcing arrangements exploit individuals in the crowd, and there has been a call for crowds to organize for their labor rights.Difficulties in collaboration of crowd members, especially in the context of competitive crowd sourcing. Crowdsourcing site InnoCentive allows organizations to solicit solutions to scientific and technological problems; only 10.6% of respondents report working in a team on their submission.
