How Planet Hunters Search for New Planets

How Planet Hunters Search for New Planets The modern age of astronomy has brought a new set of scientists to our attention: the planet hunters. These people, often working in teams using ground-based and space-based telescopes are turning up planets by the dozens out there in the galaxy. In return, those newly found worlds are expanding our understanding of how worlds form around other stars and how many extrasolar planets, often referred to as exoplanets, exist in the Milky Way galaxy. The Hunt for Other Worlds around the Sun Searching for planets began in our own solar system, with the discovery of worlds beyond the familiar naked-eye planets of Mercury, Venus, Mars, Jupiter, and Saturn. Uranus and Neptune were found in the 1800s, and Pluto wasnt discovered until the early years of the 20th century. These days, the hunt is on for other dwarf planets out in the far reaches of the solar system. One team, led by astronomer Mike Brown of CalTech continually looks for worlds in the Kuiper Belt (a distant realm of the solar system), and have notched their belts with a number of claims. So far, they have found the world Eris (which is larger than Pluto), Haumea, Sedna, and dozens of other trans-Neptunian objects (TNOs). Their hunt for a Planet X sparked worldwide attention, but as of mid-2017, nothing has been seen.   Looking for Exoplanets The search for worlds around other stars began in 1988 when astronomers found hints of planets around two stars and a pulsar. The first confirmed exoplanet around a main-sequence star occurred in 1995 when astronomers Michel Mayor and Didier Queloz of the University of Geneva announced the discovery of a planet around the star 51 Pegasi. Their find was proof that planets orbited sun-like stars in the galaxy. After that, the hunt was on, and astronomers began finding more planets. They used several methods, including the radial velocity technique. It looks for the wobble in a stars spectrum, induced by the slight gravitational tug of a planet as it orbits the star. They also used the dimming of starlight produced when a planet eclipses its star.   A number of groups have been involved in surveying stars to find their planets. At last count, 45 ground-based planet-hunting projects have found more than 450 worlds. One of them, the Probing Lensing Anomalies Network, which has merged with another network called MicroFUN Collaboration, looks for gravitational lensing anomalies. These happen when stars are lensed by massive bodies (such as other stars)   or planets. Another group of astronomers formed a group called the Optical Gravitational Lensing Experiment (OGLE), which used ground based instruments to look for stars, as well. Planet Hunting Enters the Space Age Hunting for planets around other stars is a painstaking process. It doesnt help that Earths atmosphere makes the view of such tiny objects very difficult to obtain. Stars are large and bright; planets are small and dim. They can get lost in the glow of starlight, so direct images are incredibly tough to obtain, especially from the ground. So, space-based observations provide a better view and allow instruments and cameras to make the painstaking measurements involved in modern planet-hunting.   Hubble Space Telescope has made many stellar observations and  has been used to image planets around other stars, as has the Spitzer Space Telescope. By far the most productive planet hunter has been the Kepler Telescope. It was launched in 2009 and spent several years searching out planets in a small area of the sky in the direction of the constellations Cygnus, Lyra, and Draco. It found thousands of planet candidates before it ran into difficulties with its stabilization gyros. It now hunts for planets in other areas of the sky, and the Kepler database of confirmed planets contains more than 4,000 worlds. Based on Kepler discoveries, which were aimed mostly at trying to find Earth-size planets, it has been estimated that nearly every Sun-like star in the galaxy (plus many other types of stars) has at least one planet. Kepler also found many other larger planets, often referred to as super Jupiters and Hot Jupiters and Super Neptunes.   Beyond Kepler While Kepler has been one of the most productive planet-hunting scopes in history, it will eventually stop working. At that point, other missions will take over, including the Transiting Exoplanet Survey Satellite (TESS), which will be launched in 2018, and the James Webb Space Telescope, which will also head to space in 2018. After that, the Planetary Transits and Oscillations of Stars mission (PLATO), being built by the European Space Agency, will begin its hunt sometime in the 2020s, followed by WFIRST (the Wide Field Infrared Survey Telescope), which will hunt for planets and search for dark matter, beginning sometime in the mid 2020s.   Each planet hunting mission, whether from the ground or in space, is crewed by teams of astronomers who are experts at the search for planets. Not only will they look for planets, but eventually, they hope to use their telescopes and spacecraft to get data that will reveal the conditions on those planets. The hope is to look for worlds that, like Earth, could support life.

Tips for Creating and Scoring Essay Tests

Tips for Creating and Scoring Essay Tests Essay tests are useful for teachers when they want students to select, organize, analyze, synthesize, and/or evaluate information. In other words, they rely on the upper levels of Blooms Taxonomy. There are two types of essay questions: restricted and extended response. Restricted Response - These essay questions limit what the student will discuss in the essay based on the wording of the question. For example, State the main differences between John Adams and Thomas Jeffersons beliefs about federalism, is a restricted response. What the student is to write about has been expressed to them within the question.Extended Response - These allow students to select what they wish to include in order to answer the question. For example, In Of Mice and Men, was Georges killing of Lennie justified? Explain your answer. The student is given the overall topic, but they are free to use their own judgment and integrate outside information to help support their opinion. Student Skills Required for Essay Tests Before expecting students to perform well on either type of essay question, we must make sure that they have the required skills to excel. Following are four skills that students should have learned and practiced before taking essay exams: The ability to select appropriate material from the information learned in order to best answer the question.The ability to organize that material in an effective manner.The ability to show how ideas relate and interact in a specific context.The ability to write effectively in both sentences and paragraphs. Constructing an Effective Essay Question Following are a few tips to help in the construction of effective essay questions: Begin with the lesson objectives in mind. Make sure to know what you wish the student to show by answering the essay question.Decide if your goal requires a restricted or extended response. In general, if you wish to see if the student can synthesize and organize the information that they learned, then restricted response is the way to go. However, if you wish them to judge or evaluate something using the information taught during class, then you will want to use the extended response.If you are including more than one essay, be cognizant of time constraints. You do not want to punish students because they ran out of time on the test.Write the question in a novel or interesting manner to help motivate the student.State the number of points that the essay is worth. You can also provide them with a time guideline to help them as they work through the exam.If your essay item is part of a larger objective test, make sure that it is the last item on the exam. Scoring the Essay Item One of the downfalls of essay tests is that they lack in reliability. Even when teachers grade essays with a well-constructed rubric, subjective decisions are made. Therefore, it is important to try and be as reliable as possible when scoring your essay items. Here are a few tips to help improve reliability in grading: Determine whether you will use a holistic or analytic scoring system before you write your rubric. With the holistic grading system, you evaluate the answer as a whole, rating papers against each other. With the analytic system, you list specific pieces of information and award points for their inclusion.Prepare the essay rubric in advance. Determine what you are looking for and how many points you will be assigning for each aspect of the question.Avoid looking at names. Some teachers have students put numbers on their essays to try and help with this.Score one item at a time. This helps ensure that you use the same thinking and standards for all students.Avoid interruptions when scoring a specific question. Again, consistency will be increased if you grade the same item on all the papers in one sitting.If an important decision like an award or scholarship is based on the score for the essay, obtain two or more independent readers.Beware of negative influences that can affect essay s coring. These include handwriting and writing style bias, the length of the response, and the inclusion of irrelevant material. Review papers that are on the borderline a second time before assigning a final grade.

Respond to the videos, at least 4 pages paper detailing your take awaysdouble-spaced, 12 point, Times New Roman - Movie Review Example To begin with, it is largely suggested that the United States companies were among the first to point out the necessity to pay attention towards Ethics as well as engage it into the business activities. In other words, it would not be a mistake to suggest that this awareness originated in the West. There was another term mentioned in the video – the insiders. Indeed, insider trading is one of the negative phenomena that are witnessed in the modern business world and poses a great example of unethical behavior. In addition to that, this is a problem that has been largely addressed by the American businesses. What is more important is that the notion of business ethics is often associated with different scandals that appear around it. Indeed, the majority of publications use as examples the situations when companies violated ethical rule. In other words, the public tends to learn about existence of business ethics primarily through news about scandals and not when a company is c arrying out a successful ethical policy. Finally, the message that is sent in the first video can be best explained by the actions of one of the characters. A well dressed man, who is undoubtedly a business man, was unable to provide a comprehensive definition of what business ethics is and preferred to threat the audience with a gun in stead of answering the question. In spite of the fact that this situation is somewhat exaggerated, it shows that some people in the business world find the concept of business ethics extremely inconvenient. The second video is titled Business Ethics in the 21st Century and it focuses on the role this concept plays in the contemporary times. From the very beginning the present argues that some people suggest that business ethics should be regarded as oxymoron which is a combination of world with contradicting meaning.

Juvenile Probation Essay Example | Topics and Well Written Essays - 500 words

Juvenile Probation - Essay Example The jurisprudence today looks at these youngsters as victims of society rather than as perpetrators of a crime. There are many improvements and reforms being implemented in the juvenile justice system and one of these is the increasing use of probation to help wayward youngsters avoid jail time. In this regard, a highly recommended approach is the use of information technology to improve the probation administration system by giving probation officers access to vital data in a flash. High Performance Teams – one of the best game-changers in the administration of a juvenile probation system is the use of the new information technology (IT). The use of IT is a positive influence on those who need to monitor several hundreds or even thousands of the youngsters on probation. With an IT system in place, probation officers can obtain the needed information to make their jobs easier. Information technology has long been recognized as the enabler that has a big positive impact on soci al work practice. The information contained in a database will allow probation officers to make better decisions with regards to using a correct intervention modality with regards to a particular juvenile â€Å"probationer† because they have at hand information about that youngster.

Evidentialist Method Apologetics Essay Example for Free

Evidentialist Method Apologetics Essay Introduction Apologetics comes in several different methods that are utilized to defend one’s faith and also to evangelize. One method of apologetics is Evidentialism, also known as Natural Theology. Evidentialism is probably the most popular form of apologetics, if not the one that leads the field. Our current world demands proof and supporting data and Evidentialism stresses the deliverance of accurate substantiation with the hope of bringing cynics and criticizers to the truths of Christianity. Evidentialism continues to excel in the field of apologetics and does well in confronting the major worldviews with the truths of the Christian faith that can be proven with factual analysis. This review will provide the reader with a summary of the Evidentialist Method, a critique of the Evidentialist Method, and a list of some of the more popular Evidentialists. Summary of the Evidentialist Method Apologetics comes from 1 Peter 3:15 and is most properly defined as giving a defense. In his commentary, John Walvoord states, â€Å"(apologian, the â€Å"defense† which a defendant makes before a judge; (Acts 22:1; 25:16) for their hope in Christ.† It is the impetus for Evidentialist apologetics to follow this call and seek to â€Å"Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have.† Another writer, Dan Story, states, â€Å"This is ‘evidential’ apologetics, and it works on the premise that the weight of the evidence will always support Christianity and always refute contradicting beliefs.† In order for Evidentialism to be effective, it must hold to its premise of dispensing the truths about Christianity by establishing factuality. The Evidentialist is able to take any offered topic and utilize it as evidence as they are stimulated by the antagonist’s desire to deliberate logic and reason. In Acts 19:8, the Apostle Paul was diligently â€Å"arguing persuasively about the kingdom of God.† Yet, Paul understood completely that there was none other that could open the hearts of men except God (Acts 16:14). Critique of the Evidentialist Method The Evidentialist Model for apologetics is a very sensible method to be utilized in evangelism. The world today demands physical, tangible proof and relies only on what can be seen and studied, and the Evidentialist is quite versed in the practicality and effective use of the method to clarify God’s truths. The method accepts the essential foundations of the non-believing doubter and tries to supply purposeful truth to that individual area. This reason-giving model has established its effectiveness in apologetics. There are a couple of issues of concern when it comes to the application of Evidentialism. One concern that stands out is that it adopts the thought that the fallen man can come to the supposition of Christ as Savior. It is my contention and belief that aside from the Holy Spirit man cannot come to this conclusion. However, I do feel that via the logical evidence presented, God opens the non-believer’s heart. Story clearly shows the â€Å"Holy Spirit also convicts and convinces people of the truth through extra-biblical evidences.† Popular Evidentialists History shows that the method of Evidentialism has been utilized for quite some time. There have been many superior thinkers who have used the method and have contributed greatly to the enhancement of apologetics. Although the list is long, a few of these men merit mention, William Paley (1743-1805), John Locke (1632-1704), and more contemporarily, Norman Geisler, William Lane Craig, Lee Strobel, Gary Habermas and Ravi Zacharias. These stellar thinkers have all utilized Evidentialism in furthering apologetics. There is an organization worthy of mention, Answers in Genesis, who employs the use of Evidentialism in explaining creationism to minister the truths of God, which also includes the explanation of the Gospel to many non-believing skeptics that exist within many secular evolutionist groups. Conclusion The Great Commission demands that all believers be prepared to defend their faith and be ready to offer a defense for those beliefs. There are many opposing worldviews that stand between men and salvation. When these opposing views are confronted in a loving and practical manner, much misconception can be dispelled in a practical manner. Using Evidentialism, the world that desires substantiation, a method driven apologetic is very successful. Bibliography Booth, Anthony Robert. The Two Faces of Evidentialism.

Internet - Fight for Survival of E-Commerce :: Exploratory Essays Research Papers

The Fight for Survival of E-Commerce      Ã‚   Abstract:   How can e-businesses be successful in the new millennia?   This paper looks at both the industry-wide and individual company trends that are developing, from what it takes to remain competitive, to public assurance in security.    It hasn't been an easy year for e-commerce.   With so many e-businesses failing, and just as many emerging, the key to survival has been the attraction and retention of customers.   Different companies need different approaches, however, with one being the use of online coupons.   At the same time, the industry is getting a better image as security is addressed - more specifically, the confidence of buying online with credit cards.      Creating and retaining a customer base on the Internet is not an easy task.   Different companies need to have different approaches, depending on what their product is, and who their competitors are.   To analyze these companies, we split them into type types - the niche competitor and the direct competitor.    The niche competitor is exactly what its name implies.   These are the companies with a specific niche - their customer base comes from the fact that they offer a one-of-a-kind service.   An example of this is the online auction site Ebay.   Ebay provides a service that when first introduced, was non-existent on the Internet.   Today, there is no other online auction site that even begins to rival Ebay in either its number of users and/or hits per day.   Boasting over 10 million registered users as of December of 1999, Ebay had over 3 million items listed for sale in an excess of 3,000 categories that very same month [3]. PC Data Online, a service that rates websites by the amount of traffic received, placed Ebay 8th in their monthly Top 100.   No other auction-oriented site appeared on the list [6].   For a niche competitor to be successful against similar niche competitors, however, it must offer both a good product and good advertisement.   Ebay succeeded by satura ting the market with advertisements early and quickly, and by providing an easy to use and attractive interface.   Ebay's early competitors did not do so well - while Ebay advertised on television, most did not, and most auction sites simply did not look as good as Ebay's.   Even today, Yahoo! Auctions pales in comparison to Ebay, aesthetically.   Indeed, Ebay is both a well-tuned site and household name and thus has been able to fend off and retain customers from would-be competitors such as Yahoo! Auctions, and AuctioNet.

Enduring Pak-China Relations Essay

During Prime Minister Yousaf Raza Gilani’s visit to China, there have been speculations that he undertook this ‘emergency’ trip in the aftermath of Osama bin Laden’s killing in Abbottabad by US forces. Nothing could be further from the truth. During the visit, the Chinese leadership assured Pakistan of their full support in its hour of need. Prime Minister Wen Jiabao informed Pakistan that China had urged the US to respect Pakistan’s sovereignty. In addition to agreements on banking, technical and economic cooperation, China agreed to expedite the delivery of 50 J-17F Thunder fighter jets to Pakistan. This has provoked some American Congressmen to interpret it as Pakistan’s leaning on China to countervail pressure from Washington. Contrary to speculations, this visit was not prompted by the Abbottabad incident. It was planned much before and was part of the ongoing Pak-China strategic relations. Also, 2011 marks the 60th anniversary of the Pak-China relationship and has been designated as the year of friendship between the two countries, which was reflected in the celebrations and extraordinarily warm welcome extended to Pakistan’s prime minister in China. Therefore, to suggest that the visit was organised on the spur of the moment is misleading. Pakistan and China have a longstanding relationship, especially since 1962, when China and India went to war over a disputed border. The Chinese have been steadfast friends and have supported Pakistan through thick and thin. China’s interest lies in a stable and prosperous Pakistan. They have been very generous in sharing their development and progress in the economic and technical fields and have aided Pakistan in every possible manner. Therefore, the visit of Prime Minister Gilani should not be considered as reactive. Pakistan is a sovereign country (despite challenges) and has the right to choose its friends and explore options for positive relationships other than the US. Pakistan is not bound to have a one-track relationship with the world through the US. The US raid in Abbottabad created a perception that Pakistan’s air force is weak and compromised, prompting India to remark that it could carry out similar attacks on jihadi outfits in Pakistan. Like a true friend, the Chinese have agreed to speed up the production and delivery of 50 JF-17 Thunder aircraft for Pakistan. This has not only sent a clear signal to the world that China stands by Pakistan but will actually strengthen our air defense against any such misadventure. Gwadar port: China has a keen interest that Pakistan’s vision to become a trade and energy corridor, which links Central Asia, Russia and China with the warm waters of the Arabian Sea should become a reality. If the Gwadar Port develops and is linked with rail and road infrastructure, China’s interests will also be served. Compared to shipping from the eastern seaports, trade through Pakistan will tremendously ease trade for China. China wants to develop its relatively undeveloped interior western regions. The best way to achieve this is to provide an outlet for the region through Gwadar. The Chinese have agreed to take over the operation of Gwadar Port after the contract with the Singapore Port Authority expires in anticipation of this dream becoming a reality. China has stakes in a developed and prosperous Pakistan and is ready to help it grow. Is Pakistan ready to avail this opportunity and develop the capacity to take advantage of Chinese generosity? SECOND EDITORIAL: Attack on US Consulate staff Another day, another attack. An improvised explosive device (IED) struck two bulletproof Land Cruisers of the US Consulate staff in Peshawar on Friday, injuring 11 people and killing one passerby. Two consulate personnel suffered minor injuries in this first attack on US diplomats after the operation that killed Osama bin Laden. This comes in a sequence of similar attacks that have been taking place throughout the country since al Qaeda’s leader was killed, including against Saudi personnel in their Karachi consulate. It is feared that this is just the beginning as the extremists might be getting warmed up to fulfil their pledge of revenge against Pakistan, the US and other countries that had a part to play in bin Laden’s death. Other NATO countries too are on the terrorists’ hit list. The Taliban have claimed responsibility for the Peshawar attack and have declared it retribution for bin Laden’s death at the hands of US Navy SEALs. When such a red alert situation exists in the country, it is shameful that adequate security measures are still lacking to prevent such attacks from taking place. Just as Osama was a high value target for the US, likewise, US, European, Saudi and even Pakistani citizens are high-value targets for the militants. To have foreign and our own citizens under threat on our shores and to be woefully unequipped to protect them is pathetic, to say the least. It is almost as if the security forces in Pakistan are too de-motivated in the face of a murky, bloodthirsty enemy. The area where this latest attack took place, University Town, is considered to be one of the more posh residential locations in Peshawar. It is a community where foreigners usually live. For a militant onslaught to take place there shows that even the most well-off of places is unsafe, what to say of the rest of the country. The security and law enforcement agencies have to get their act together. Our intelligence establishment cannot afford to fall asleep (again?) in the wake of the bin Laden episode and our police and security forces need better methods of detection and prevention. Arrangements must be made to better police the streets and allow citizens, whether international or local, to move about without incurring the risk of being blown to bits. * Home | Editorial

Non Parametric Test

Non Parametric Test is a kind of statistical test that was discovered by Wolfowitz. This test covers a variety of categories and these are the independent samples, dependent samples and the variables relationship with co- variables. To contrast and differentiate measurements is a hard thing to do, one can choose parametric and nonparametric. Non parametric test are those tests that has no postulates about arrangement of population. There a number of nonparametric tests and these includes the Mann- Whitney Test, Wilcoxon and the Kruskal- Wallis test. Mann- Whitney Test is comparing two independent random samples. It has its postulates or assumptions and these are the taking of spontaneous segment of populations, autonomy within data’s gathered and its common independence, its scale is ordinal. The Wilcoxon test or the Wilcoxon signed- rank test is the test that which serves as a replacement of Student’s T test. This was discovered by Frank Wilcoxon. This is comparing a dissimilar measurement that is why it is needed to measure data’s at a gap of measurement. Kruskal- Wallis test, a one way analysis of variance and is used for small samples, it compares unpaired groups. Prism is being used in performing this test. These non parametric tests are usually used in ranking order such as movie reviews. But due to lesser postulates, these non parametric tests are full of vigor or vital. Non parametric tests are easy to use and is much simple than the parametric test. This test can be use on determining the population of those depressed people, emotionally disturbed and mentally ill and it can also be used to know the level or the rank of the most significant reasons why people get emotionally unstable and eventually get depressed.

Working Memory The WritePass Journal

Working Memoryï » ¿ Write-Up Working Memoryï » ¿ Write-UpMethodParticipantsMaterialsDesignProcedureStatistical analysisDiscussionReferencesRelated Write-Up The field of memory provides excellent opportunity for research, drawing theoretical models and implementing them to check their validity. Working memory, in psychology, is a memory system that holds information to perform various verbal and non-verbal (even physical) tasks. It is very important from the viewpoint of processing information and enacting it in day-to-day life. Though a simple three stage model for memory (Encoding, storage and retrieval) was proposed initially, experts like Baddeley proposed that working memory is much beyond these three phases and memory functions of short-term memory and long-term memory are very complex in comparison to what initial chunking of memory into theoretical aspects initially suggest (Becker Morris, 1999).   He introduced a novel approach to depict working memory as a not as three-part system that temporarily holds information as people perform cognitive tasks but a perennial work-desk on which information is manipulated and assembled t o help us comprehend decide, and in problem-solving (Baddeley, 1996, 2003). According to Baddeley’s view of working memory, we can pictorially imagine a managerial executive (Central executive memory) with two helpers (Phonological loop Visuo-spatial working loop) (Hamilton, Coates Hefferman, 2010; DeRenzi Nischell, 1975). This theory and its fractionization have neuropsychological evidence, experimental evidence and developmental evidence. A study states that left posterior hemisphere of the brain is actively involved in working memory. Other studies show that even right posterior is actively involved but in working memory but non-visual aspects. It might be involved in spatial aspects. Despite the heavy argument, involvement of different brain regions in working memory (Phonological and visuo spatial) establishes a base for neuro-psychological evidence (Vallar Baddeley, 1984; Hamilton, Coates   Hefferman, 2010). Laboratory based experiments show how visual short-term memory task is strongly disrupted by visual as opposed to spatial interference, and also spatial memory task was simultaneously more strongly disrupted by spatial interference. This double dissociation supports the theoretically proposed fractionation of working memory (Klauer Zhao, 2004). Developmental evidence suggests that visual subcomponent of the visuo-spatial sketchpad is distinct from the spatial subcomponent as seen in children aged 5-6, 8-9 and 11-12 (Logie Pearson, 1997). Thus, arising from strongly evidenced studies, Logie presents a distinct model of two separate systems (Visual and Spatial) (DeRenzi Nischell, 1975). The visual storage aspect stores information about form and colour whereas spatial control takes care of aspects pertaining to locomotion, limb movements and also rehearsal of information (or series of information in visual cache) (Logie Pearson, 1997). The proposed study explores the topic of fractionalisation of memory in lines with the above mentioned strong theoretical and research based evidence. However, the trajectory of interest is along the lines of research done by Logie and Pearson (1997) in developmental field. This study examines the visual and spatial development in children and adults. There may be many limitations pertaining to use of methodology. The visual recall of design and Corsi blocks are two distinct materials, not only in terms of format but also in terms of material to be recalled. Thus comparison of two unequal factors may raise questions about the validity and outcomes of the studies. Logie and Pearson’s study focussed solely on children of different age groups, but since it is purported to measure visual and spatial aspects of working memory under a developmental pathway, this study will use children and adults are subjects (Logie Pearson, 1997; Klauer Zhao, 2004). Other arguments against the reliability and objectivity of studies in this area have been in terms of usage of participants and individual, genetic, ethnic and anthropologic differences within the patterns of development. It is not possible to outline a single or a group of factors that predict the pathway of development. Our research hypothesis is designed to measure two questions. The first part of the hypothesis seeks to inquire whether according to the fractionation; the visual and spatial systems should develop at different speeds in humans. In accordance to the first part of the hypothesis, the second part inquires whether the developmental trajectory for visual system is shallower than spatial system. Method Participants The study has 139 participants in all comprising of 65 (46.8%) children and 74 (53.2%) adults. Among these participants are 56 (40.3%) males and 83 (59.7%) are females. The mean age for boys is 15.65 years and that for girls is 18.5 years. Materials Two basic materials (tests) have been utilised viz: Visual recall of designs and Corsi Blocks. The recall of design is a paper-pencil task that requires the experimenter to show a particular design on paper to participants for 5 seconds and the participant recalls it by drawing it on paper (Logie Pearson, 1997). The Corsi test presents a blue board with nine wooden cubes. The experimenter taps out a sequence of blocks (in increasing order after each successful completion) and the participant taps out the blocks in exactly the same sequence (Fischer, 2001). Design The variables design in a classroom based experimental condition testing factors between subjects (Adults, Children) and within subjects (Males, females) performance of Recall of design and Corsi. The visual and spatial working memory development are the Independent variables whereas the developmental trajectory is the dependent variable. Procedure In a classroom settings, both children and adult group were individually given tasks performance on Visual recall of design and Corsi block task. The scores of recall of design and corsi test were done during task administration itself. Calculated scores for each individual in the adult and the children group are put up before conducting statistical analysis. Statistical analysis Statistical analyses used can be divided into Descriptive statistics and inferential statistics. SPSS 19.0 was used for data analyses. Graphs, Histograms and Comparitive bar charts along with mean and median related data falls into descriptive statistics category. We have also conducted two unrelated t-tests; one to compare children’s recall of design with adults and the other one to compare children’s Corsi scores with that of adults. The mean score of children on visual memory is 14.17.     (Mean=11.02, sd=1.727) and that of adults is 14.42 (Mean= 17.45, sd=2.765). The mean score of children on spatial memory is 11.02 (Mean=14.17,sd=2.275) and that for adults is 17.45 (Mean= 14.42, sd=2.196). The above table clearly shows that with respect to the spatial component there is a statistically significant difference between the adult mean and children’s mean (p=0.000) which is well below the 0.05 threshold.   In fact from the above table it can be seen that the adult mean score is 17.45 whilst that of the children is 11.02 meaning that on average the adults scored about 6.4 more than the children. The above table clearly shows that there is a statistically significant difference between the adult mean and children’s mean   on spatial component (p=0.000) which is well below the 0.05 threshold which is very highly significant The above table clearly shows that in terms of the visual component there is no statistically significant difference between adult mean and children’s mean (p0.5) which exceeds the 0.05 threshold.   It depicts how the mean difference between adults and children in relation to the visual component is very small resulting in no statistically significant difference in mean scores. Since there is high significance between the children and adult’s spatial component but no statistical significance between children and adult’s visual component, we can say that there might be a different trajectory in children and adult’s development patterns. It doesn’t however completely fulfil the hypothesis. Discussion The findings do not support the hypothesis in all earnest. There is no correlation between children and adult scores on visual component but there is a very significant relationship between children and adult scores on spatial component. It may be said that the difference has emerged because of the previously raised issue of different methods. Since, Corsi and Recall of design are two distinct tasks, it can be argued that their performance cannot be correlated. However, since the spatial component shows good correlation, it signifies that the trajectory may be well defined and that it develops more easily. However, not much light is thrown on why the results have come up the way they have. Further research may be interested in using Multiple regression to predict the possible factors that may have caused a high correlation in spatial scores and if there are any common factors in children and adults, they might as well be highlighted. However, like previous studies, this study support s the Logie -Pearson model as well as justifies the fractionation approach given by Baddeley. Memory is much beyond its’ structural and functional aspects. Though initial divisions on memory and development of theories have described functions and its’ aspects at a superficial level, this research has gone in depth to investigate difference in developmental trajectories. Since, it is a part of developmental aspect, it has many possibilities of further research (Baddeley, 2003; Logie Pearson, 1997).

7 Types of Female Characters in Shakespeares Plays

7 Types of Female Characters in Shakespeare's Plays Certain types of female characters often resurface in Shakespeare’s plays, telling us a great deal about his view of women and their status in Shakespeares time. The Bawdy Woman These characters are sexualized, cheeky and flirtatious. They are often working-class characters such as the Nurse in Romeo and Juliet, Margaret in Much Ado about Nothing or Audrey in As You Like It. Mainly speaking in prose, as befitting their low social status, these characters often use sexual innuendo when conversing. Low-class characters like these can get away with more risquà © behavior- perhaps because they have no fear of losing social status. The Tragic Innocent Woman These women are often pure and chaste at the beginning of the play, and tragically die once their innocence is lost. In stark contrast to his presentation of bawdy women, Shakespeare’s treatment of young innocent women is fairly brutal. Once their innocence or chastity is taken away, they are literally killed to signify this loss. These characters are generally courtly, high-born characters such as Juliet from Romeo and Juliet, Lavinia from Titus Andronicus or Ophelia from Hamlet. Their high social standing makes their demise seem all the more tragic. The Scheming Femme Fatal Lady Macbeth is the archetypal femme fatal. Her manipulation of Macbeth inevitably leads them to their deaths: she commits suicide and he is slain. In her ambition to become Queen, she encourages her husband to murder. King Lear’s daughters, Goneril and Regan, plot to inherit their father’s fortune. Once again, their ambition leads them to their deaths: Goneril stabs herself after poisoning Regan. Although Shakespeare seems to appreciate the intelligence at work in his femme fatal characters, allowing them to manipulate the men around them, his retribution is brutal and unforgiving. The Witty, but Unmarriable Woman Katherine from The Taming of The Shrew is a prime example of the witty but unmarriable woman. Feminists have commented that their enjoyment of this play is marred by the fact that a man literally â€Å"breaks† Katherine’s spirit when Petruchio says â€Å"Come on  and kiss me, Kate.† Should we really celebrate this as a happy ending? Similarly, in the plot to Much Ado About Nothing, Benedick ultimately conquers the feisty Beatrice by saying, â€Å"Peace, I will stop your mouth.† These women are presented as clever, bold and independent but are put in their place by the end of the play. The Married Off Woman Many of Shakespeare’s comedies end with an eligible woman being married off – and therefore being made safe. These women are often very young and passed from their father’s care to their new husband’s. More often than not, these are high-born characters such as Miranda in The Tempest who is married to Ferdinand, Helena and Hermia in A Midsummer Night’s Dream and Hero in Much Ado About Nothing. Women Who Dress as Men Rosalind in As You Like it and Viola in Twelfth Night both dress as men. Consequently, they are able to play a more active role in the play’s narrative. As â€Å"men†, these characters have more freedom, highlighting the lack of social liberty for women in Shakespeare’s time. Falsely Accused of Adultery Women in Shakespeare’s plays are sometimes wrongly accused of adultery and suffer greatly as a result. For example, Desdemona is killed by Othello who supposes her infidelity and Hero falls terribly ill when she is falsely accused by Claudio. It seems that Shakespeare’s women are judged by their sexuality even when they remain faithful to their husbands and husbands-to-be. Some feminists believe that this demonstrates male insecurity about female sexuality.

Write an evaluation of a published macroeconomic forecast Essay

Write an evaluation of a published macroeconomic forecast - Essay Example This means that there is continuous growth in future, which is brought by the banks’ new advances made on the credits extended to customers. In the next quarter the economy is expected to perform even much better. Another contributor to the economic growth is the housing for the last more than 5 months, sales of real estates hasbeen evident. This is backed by the new modern homes that have been constructed and some which are still under construction. For example, CoreLogic Home Price Index rose by 1.1% in a year. This is according to chapter three of the (economic forecast publication r April 2014). In comparison, the housing construction and sales vary by 9%, construction rate being higher than the sales. This is a growth indicator. Manufacturing and processing sectors have added wonderful growth indicators to the economic growth. The May returns of this year are anticipated to be the highest for the last three years. This follows last years 5% growth, which is highest for the last three years now. Key assumptions here are that: the government does not take care of the borrowers where the cost of loans is very high. The government assumes that there is general growth. They don’t take care of the private sectors and individuals who bear the high cost of economic growth through coast of loans. The second assumption is the policy of selling the homes. It is more beneficial to hold investments than sales, especially real estates. This is in regard to the principle of the investment multiplier concept. The audience of this information is the potential investors, shareholders and the government agencies. Some areas have been exaggerated. Firstly, the sales of assets are lower in long term growth in GDP. Anothe r one is the high cost of loans shifted to borrowers. The borrowers are economically affected. Labor market shows a negative image compared to developments as said earlier in the US economic

So that is where modern carnival comes from: in order to protect oneself from the evil spirits, one has to dress up and pose as these spirits. The Church, normally respected by the Americans, considers that when imitating evil spirits, people take over demonic disposition and destroy their appearance that was given to them by God. Such behavior contradicts Christian foundations; however the Americans never cease being true believers. Also there are usually acts of â€Å"petty vandalism† which the Church also does not approve of – children break glasses, burn trees, etc. Though in the 1920s the scouts called to introduce the practice of â€Å"trick or treat† instead, sometimes people still like to commit something they would not usually do in their normal life. Respectable businessmen are likely to turn over garbage bins, stewardesses (mainly on domestic flights) dress up like a witches or fairies, teachers have no less fun than their students. It is really an unusual tradition – to wear a mask and play a role quite opposite to what one is in the society. Both children and grown-ups enjoy themselves and have fun meeting November in the costumes of witches and vampires, throwing eggs, taking part in the â€Å"best costume† competitions, and eating pumpkin dishes. It reveals the Americans being in need of throwing away from time to time their â€Å"normal† social roles and taking up something quite uncommon. Americans particularly care about their children and are usually good parents. The paradox is, though some scientists think it can traumatize the child’s mind, demoralize the children and even demonize them, American people treat Halloween as a means to please their kids. Also, more and more
