    2013-08-01

    MESSAGE FROM THE EDUCATION COMMITTEE: In 2013, the Education Committee of the Human Genetics Society of Australasia (HGSA) established the DNA Day Essay Contest in Australia and New Zealand. The contest was first established by the American Society of Human Genetics in 2005 and the HGSA DNA Day Essay Contest is adapted from this contest via a collaborative partnership. The aim of the contest is to engage high school students with important concepts in genetics through literature research and reflection. As 2013 marks the 60th anniversary of the discovery of the double helix of DNA by James Watson and Francis Crick and the 10th anniversary of the first sequencing of the human genome, the essay topic was to choose either of these breakthroughs and explain its broader impact on biotechnology, human health and disease, or our understanding of basic genetics, such as genetic variation or gene expression. The contest attracted 87 entrants in 2013, with the winning essay authored by Patrick Yates, a Year 12 student from Melbourne High School. Further details about the contest including the names and schools of the other finalists can be found at http://www.hgsa-essay.net.au/. The Education Committee would like to thank all the 2013 applicants and encourage students to enter in 2014.

  7. [Suicide -- an essay trying to reveal the theme].

    Science.gov (United States)

    Sampaio, M A; Boemer, M R

    2000-12-01

    This essay proposes to reveal facets of the suicide through the discourse of different authors treating this theme as well as through contacts that I was able to have in my nursing training, through my academic trajectory. This trajectory includes an incursion by phenomenological ideas, mainly by the ideas of Heidegger and his existential analysis of the man as being-there. In this way, the understanding of a person who decides to finalize his/her existence, can be, by the existential analysis perspective, a way to reconstruct and redimension his/her existential perspectives.

In addition, NRAO is developing enhanced data visualization techniques and data-processing recipes to assist radio astronomers in making quality images and in combining radio data with data collected at other wavelengths, such as visible-light or infrared, to make composite images. "We encourage all our telescope users to take advantage of these techniques to showcase their research," said Juan Uson, a member of the NRAO scientific staff and the observatory's EPO scientist. "All these efforts should demonstrate the vital and exciting roles that radio telescopes, radio observers, and the NRAO play in modern astronomy," Lo said. "While we want to encourage images that capture the imagination, we also want to emphasize that extra effort invested in enhanced imagery also will certainly pay off scientifically, by revealing subtleties and details that may have great significance for our understanding of astronomical objects," he added. Details of the NRAO Image Contest, which will become an annual event, are on the observatory's Web site. The observatory will announce winners on October 15.

    The Cassini Outreach Team of NASA's Jet Propulsion Laboratory is being organizing a brilliant school contest in Astronomy focusing in the Saturnian system. This essay contest provides school students all around the worlds with the opportunity to get involved in astronomy and astrophysics and planetary sciences in particular. From 2010 the 'Cassini Scientist for a Day' contest has being one of the most successful as well as important outreach activities of ESA and NASA in Greece with hundreds of participants all over Greece. The number of participants is growing rapidly every year. This type of school competition in Greece is particularly important since Astronomy and Astrophysics and Space Sciences, although very popular, are not included in the school curricula and thus students rarely have the opportunity to experience and participate actively in these subjects. For the years 2010 and 2011, the Space Physics Group of the Astronomy, Astrophysics and Mechanics section of the University of Athens in association with external colleagues has been selected as the co-ordinator of NASA for the competition in Greece. Under the guidance of Cassini Outreach team, the members of the Space Physics Group have informed, explained and spread the rules of the competition at primary, secondary and high schools all over Greece. In general, the students have the option to choose Cassini monitoring between three targets of the Saturnian system, which the participants show that will bring the best scientific result. Their arguments should be summarized in an essay of 500 words more or less. They also have the option to do team work through groups of maximum three students. The participation in the contest for 2010 was unexpectedly high and thoroughly satisfied. The winners awarded through a ceremony which was held in the largest amphitheater at the central building of the University of Athens, that was fully packed. The following year 2011 the participation increased up to 300% while

  1. Patents, Inducement Prizes, and Contestant Strategy

    DEFF Research Database (Denmark)

    Davis, Jerome; Davis, Lee N.

    2006-01-01

    Debate over the merits of patents versus inducement prizes has tended to ignore the signaling roles of patents, and totally ignores the impact of patent signaling on prize contests. This paper asks: How does patent signaling affect the strategic choices of firms considering entering prize contests......? First, we consider contests that do not allow patenting, then contests that do. If patenting is not allowed, we argue, patent-holders, both internal and external to the contest, can adversely impact prize contests by claiming prize winner violation of their patents, and suing for damages. The likelihood...... of such challenges being made can deter entry, particularly in contests requiring large sunk costs. Furthermore, the firm's decisionmaking process will discriminate against entering prize contests and favor R&D projects with patentable outcomes. Together, these problems may circumscribe any future wider role...

  2. Contest experience and body size affect different types of contest decisions.

    Science.gov (United States)

    Chen, Yu-Ju; Hsu, Yuying

    2016-11-01

    This study examined the relative importance of contest experience and size differences to behavioral decisions over the course of contests. Using a mangrove rivulus fish, Kryptolebias marmoratus, we showed that although contest experience and size differences jointly determined contest outcomes, they affected contestants' interactions at different stages of contests. Contest experience affected behavioral decisions at earlier stages of contests, including the tendency and latency to launch attacks, the tendency to escalate contests into mutual attacks and the outcome of non-escalated contests. Once contests were escalated into mutual attacks, the degree of size difference affected the fish's persistence in escalation and chance of winning, but contest experience did not. These results support the hypothesis that contest experience modifies individuals' estimation of their fighting ability rather than their actual strength. Furthermore, (1) in contests between two naïve contestants, more than 60 % of fish that were 2-3 mm smaller than their opponent escalated the contest to physical fights, even though their larger opponents eventually won 92 % of escalated fights and (2) fish with a losing experience were very likely to retreat in the face of an opponent 2-3 mm smaller than them without escalating. The result that a 2-3 mm size advantage could not offset the influence of a losing experience on the tendency to escalate suggests that, as well as depending on body size, the fish's physical strength is influenced by other factors which require further investigation.

  9. Essays in energy economics

    Energy Technology Data Exchange (ETDEWEB)

    Malischek, Raimund

    2016-10-25

    This thesis presents four essays in energy economics. The first essay investigates one of the workhorse models of resource economics, the Hotelling model of an inter-temporally optimizing resource extracting firm. The Hotelling model provides a convincing theory of fundamental concepts like resource scarcity, but very few empirical validations of the model have been conducted. This essay attempts to empirically validate the Hotelling model by first expanding it to include exploration activity and market power and then using a newly constructed data set for the uranium mining industry to test whether a major resource extracting mining firm in the industry is following the theory's predictions. The results show that the theory is rejected in all considered settings. The second and third essays investigate the difference in market outcomes under spot-market based trade as compared to long-term contract based trade in oligopolistic markets with investments. The second essay investigates analytically the difference in market outcomes in an electricity market setting, showing that investments and consumer welfare may be higher under spot-market based trade than under long-term contracts. The third essay proposes techniques to solve large-scale models of this kind, empirically, by exploring the practicability of this approach in an application to the international metallurgical coal market. The final essay investigates the influence of policy uncertainty on investment decisions. With France debating the role of nuclear technology, this essay analyses how policy uncertainty regarding nuclear power in France may feature in the French and European power sector. Applying a stochastic model for the European power system, the analysis shows that the costs of uncertainty in this particular application are rather low compared to the overall costs of a nuclear phase-out.

  10. Essays in energy economics

    International Nuclear Information System (INIS)

    Malischek, Raimund

    2016-01-01

    This thesis presents four essays in energy economics. The first essay investigates one of the workhorse models of resource economics, the Hotelling model of an inter-temporally optimizing resource extracting firm. The Hotelling model provides a convincing theory of fundamental concepts like resource scarcity, but very few empirical validations of the model have been conducted. This essay attempts to empirically validate the Hotelling model by first expanding it to include exploration activity and market power and then using a newly constructed data set for the uranium mining industry to test whether a major resource extracting mining firm in the industry is following the theory's predictions. The results show that the theory is rejected in all considered settings. The second and third essays investigate the difference in market outcomes under spot-market based trade as compared to long-term contract based trade in oligopolistic markets with investments. The second essay investigates analytically the difference in market outcomes in an electricity market setting, showing that investments and consumer welfare may be higher under spot-market based trade than under long-term contracts. The third essay proposes techniques to solve large-scale models of this kind, empirically, by exploring the practicability of this approach in an application to the international metallurgical coal market. The final essay investigates the influence of policy uncertainty on investment decisions. With France debating the role of nuclear technology, this essay analyses how policy uncertainty regarding nuclear power in France may feature in the French and European power sector. Applying a stochastic model for the European power system, the analysis shows that the costs of uncertainty in this particular application are rather low compared to the overall costs of a nuclear phase-out.

  12. Between consensus and contestation.

    Weale, Albert

    2016-08-15

    Purpose - Noting that discussions of public participation and priority setting typically presuppose certain political theories of democracy, the purpose of this paper is to discuss two theories: the consensual and the agonistic. The distinction is illuminating when considering the difference between institutionalized public participation and contestatory participation. Design/methodology/approach - The approach is a theoretical reconstruction of two ways of thinking about public participation in relation to priority setting in health care, drawing on the work of Habermas, a deliberative theorist, and Mouffe, a theorist of agonism. Findings - The different theoretical approaches can be associated with different ways of understanding priority setting. In particular, agonistic democratic theory would understand priority setting as system of inclusions and exclusions rather than the determination of a consensus of social values, which is the typical deliberative way of thinking about the issues. Originality/value - The paper shows the value of drawing out explicitly the tacit assumptions of practices of political participation in order to reveal their scope and limitations. It suggests that making such theoretical presuppositions explicit has value for health services management in recognizing these implicit choices.

  20. Corporate contestability and corporate expropriation

    Directory of Open Access Journals (Sweden)

    Abdul Hadi Zulkafli

    2016-12-01

    Full Text Available This paper presents evidence on the role of ownership in dealing with corporate expropriation of listed companies in Malaysia. From the perspective of expropriation, a single controlling shareholder is always associated with such behavior due to their power and control at the expense of minority shareholder. However, subsequent individual or coalition of large shareholders can be an important corporate governance tool by providing effective monitoring that would lessen the possibility of expropriation by the controlling shareholder. Relating to that, this study evaluates the role of controlling and large shareholders in dealing with corporate expropriation. It is found that there is a negative relationship between single controlling shareholders and dividend payout ratio indicating that firms with only controlling shareholder will pay a lower dividend due to possible expropriation through profit diversion by controlling shareholder. Using Herfindahl Index as a proxy for ownership contestability, the presence of large shareholders along with controlling shareholder has a positive relationship with dividend payout implying that increased contestability helps to curb the power of controlling shareholder to expropriate fund for their own benefit. In accordance with agency theory, the outcome suggests that large shareholders play a monitoring role in minimizing the Type II agency problem. It is also verifying the argument made based on the Catering Theory of Dividend that the presence of large shareholder brings benefit to all shareholders as they are able to reduce profit diversion by demanding for higher dividend

In shamanic practice it is not the personal ability (skill or physical power that provides a challenger victory in conflict, but obtaining spirits-helpers more powerful than those of his or her rival. The predominate role of these fantastic personages/helpers in tales that represent invisible spirit helpers perform real shamanic praxis, explains the loser’s unconditional submission and readiness to sacrifice their freedom or life to the winner. It also clarifies the motivation of the initiators of these contests and games: by means of gathering a great number of competitors, such shamans solve their personal spiritual problems, such as the need to overcome their adversaries or find allies in the struggle against their opponents.

  7. Essays in microeconomics

    Science.gov (United States)

    Davies, Tim

    This dissertation consists of three essays in applied microeconomics. Each essay explores a different issue of economic interest. The essay in Chapter 2 describes an experiment designed to investigate if using assets with an intrinsic value that increases over time leads to persistent undervaluation in laboratory asset trading markets. This question has not previously been investigated by researchers. Results from ten sessions are reported. Three used assets with an intrinsic value that decreased over time. The results from these sessions are consistent with the findings by prior researchers who frequently observed price bubbles in laboratory asset trading experiments. The remaining seven sessions used assets with an intrinsic value that increased over time. In all these sessions trading generally occurred at prices below the asset's intrinsic value. In Chapter 3, in an essay co-authored with Adrian Stoian, we study road running races. Tournaments, where ordinal position determines rewards, are an important component of our economy. By studying sporting tournaments, we hope to shed light on the nature of other economically significant tournaments where data may be less readily available. We separately quantify the sorting and incentive effects of tournament prizes by employing a novel two-part model which we apply to a unique data set of road running race results. We present a counterfactual example of how a hypothetical change in prizes would be predicted to change race participation and speed. In Chapter 4, in an essay co-authored with Jedidiah Brewer and Joseph Cullen, we examine the combined effects of the locations and the brands of retail gasoline outlets in Tucson, Arizona on market prices. We apply an innovative approach to model the impact of competing gas stations that avoids limiting analysis to predetermined nearby locations. We show that increased brand diversity is associated with higher prices and that gas stations affiliated with mass

  8. Payoff Shares in Two-Player Contests

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available In imperfectly discriminating contests with symmetric valuations, equilibrium payoffs are positive shares of the value of the prize. In contrast to a bargaining situation, players’ shares sum to less than one because a residual share of the value is lost due to rent dissipation. In this paper, we consider contests with two players and investigate the relationship between these equilibrium shares and the parameters of a class of asymmetric Tullock contest success functions. Our main finding is that any players’ shares that sum up to less than one can arise as the unique outcome of a pure-strategy Nash equilibrium for appropriate parameters.

  9. Three Essays on Macroeconomics

    Science.gov (United States)

    Doda, Lider Baran

    This dissertation consists of three independent essays in macroeconomics. The first essay studies the transition to a low carbon economy using an extension of the neoclassical growth model featuring endogenous energy efficiency, exhaustible energy and explicit climate-economy interaction. I derive the properties of the laissez faire equilibrium and compare them to the optimal allocations of a social planner who internalizes the climate change externality. Three main results emerge. First, the exhaustibility of energy generates strong market based incentives to improve energy efficiency and reduce CO 2 emissions without any government intervention. Second, the market and optimal allocations are substantially different suggesting a role for the government. Third, high and persistent taxes are required to implement the optimal allocations as a competitive equilibrium with taxes. The second essay focuses on coal fired power plants (CFPP) - one of the largest sources of CO2 emissions globally - and their generation efficiency using a macroeconomic model with an embedded CFPP sector. A key feature of the model is the endogenous choice of production technologies which differ in their energy efficiency. After establishing four empirical facts about the CFPP sector, I analyze the long run quantitative effects of energy taxes. Using the calibrated model, I find that sector-specific coal taxes have large effects on generation efficiency by inducing the use of more efficient technologies. Moreover, such taxes achieve large CO2 emissions reductions with relatively small effects on consumption and output. The final essay studies the procyclicality of fiscal policy in developing countries, which is a well-documented empirical observation seemingly at odds with Neoclassical and Keynesian policy prescriptions. I examine this issue by solving the optimal fiscal policy problem of a small open economy government when the interest rates on external debt are endogenous. Given an

  15. Bitcoin Mining as a Contest

    Directory of Open Access Journals (Sweden)

    Nicola Dimitri

    2017-09-01

    Full Text Available This paper presents a simple game theoretic framework, assuming complete information, to model Bitcoin mining activity. It does so by formalizing the activity as an all-pay contest: a competition where participants contend with each other to win a prize by investing in computational power, and victory is probabilistic. With at least two active miners, the unique pure strategy Nash equilibrium of the game suggests the following interesting insights on the motivation for being a miner: while the optimal amount of energy consumption depends also on the reward for solving the puzzle, as long as the reward is positive the decision to be an active miner depends only on the mining costs. Moreover, the intrinsic structure of the mining activity seems to prevent the formation of a monopoly, because in an equilibrium with two miners, both of them will have positive expected profits for any level of the opponent’s costs. A monopoly could only form if the rate of return on investment were higher outside bitcoin.

  16. Essay Genre in Tatar Journalism

    Directory of Open Access Journals (Sweden)

    Aigul A. Guseinova

    2017-11-01

    Full Text Available In this article, an essay is considered as a journalistic genre in the context of modern Tatar journalism. Using the example of works by contemporary authors in the Tatar-speaking periodicals of Russia, the main genre and the semantic features of this genre are studied. An essay is a publicistic form to reflect on the topical issues of Russian reality. The reproduction of a fact is not so important for an essay. An important role is played by the description of the author's impressions, reflections and emotions. The periodical press has many materials in the Tatar language in which the author's opinion, author's principle and subjective opinion are strongly expressed. In fact, during the last decades of the twentieth century and the beginning of the twenty-first century there was a surge of essays in modern journalism. Due to some political events in Russia during the early 90s of the twentieth century, it was possible to express their thoughts and speak on the urgent problems in society openly in comparison with the Soviet reality. The object of research is essayism as a kind of journalistic creativity, the subject of the study is the essay genre in Tatar journalism. The empirical basis of the work consisted of the essays from Tatar journalists, publicists and writers. Provided that the personality of an author is one of the effectiveness factors concerning the publications in the genre of essay, the essayization of texts in Tatar journalism will be increased in the future.

    A pictorial essay is a type of educational article that aims to provide both textual and visual portrayals of a topical issue. It usually consists of a short unstructured abstract, brief introduction, subheadings to organise the material and a summary. The number of references is limited to a few key articles, typically, eight to 15, or fewer. The text is usually short, often approximately 1,000 to 2,000 words in length, with much of the message contained in the figure legends. This type of article allows for a large number of figures, typically up to 20 figures or 30 figure parts. The main criteria for publication are currency, educational value and high quality of illustrations.

    Bäckman, Claes

    In Denmark and in many countries around the world, housing markets are of considerable importance for households and policy-makers alike. As the boom and bust in the US and Danish housing market so aptly demonstrated, disruptions in the housing market potentially have wide-ranging consequences...... for individual households and for the aggregate economy. Housing is important because we all have to live somewhere, but also because it serves as a considerable source of both wealth and debt. As such, housing market policy can not only create vast benefits for many, but can also have substantial negative...... impacts for all, and should therefore be a topic of major interest for economists and policy makers alike. This Ph.D. thesis, entitled “Essays on Housing Markets”, analyzes the Danish housing market during the 2000s, with a focus on how policy changes affected house prices and how changes in house prices...

    Image reconstruction in optical interferometry has gained considerable importance for astrophysical studies during the last decade. This has been mainly due to improvements in the imaging capabilities of existing interferometers and the expectation of new facilities in the coming years. However, despite the advances made so far, image synthesis in optical interferometry is still an open field of research. Since 2004, the community has organized a biennial contest to formally test the different methods and algorithms for image reconstruction. In 2016, we celebrated the 7th edition of the "Interferometric Imaging Beauty Contest". This initiative represented an open call to participate in the reconstruction of a selected set of simulated targets with a wavelength-dependent morphology as they could be observed by the 2nd generation of VLTI instruments. This contest represents a unique opportunity to benchmark, in a systematic way, the current advances and limitations in the field, as well as to discuss possible future approaches. In this contribution, we summarize: (a) the rules of the 2016 contest; (b) the different data sets used and the selection procedure; (c) the methods and results obtained by each one of the participants; and (d) the metric used to select the best reconstructed images. Finally, we named Karl-Heinz Hofmann and the group of the Max-Planck-Institut fur Radioastronomie as winners of this edition of the contest.

  1. Morgellons: contested illness, diagnostic compromise and medicalisation.

    Science.gov (United States)

    Fair, Brian

    2010-05-01

    The case of Morgellons illustrates how the emergence of a new medically contested illness intersected with and impacted on the diagnostic processes of an existing uncontested psychiatric condition, Delusional Parasitosis (DP). More specifically, the sociopolitical processes at play in the contested illness, Morgellons, dubiously reflect patient empowerment, as well the resilience and power of medical jurisdiction. This research offers insights into the contested illness and medicalisation literatures, and aims to bridge these two approaches towards the relationship between patient empowerment and medical authority, which I do through the notion of doctor-patient compromise. The data for this research come from a comprehensive qualitative analysis of Morgellons discourse through four key sources: the pro-Morgellons website Morgellons.org; the anti-Morgellons website Morgellonswatch.com; the popular media's portrayal of Morgellons; and the DP and Morgellons articles published in peer-reviewed medical journals, as made available on PubMed.

    The first essay measures the impact of an outbreak of pediatric leukemia on local housing values. A model of residential location choice is used to describe conditions under which the gradient of the hedonic price function with respect to health risk is equal to household marginal willingness to pay to avoid pediatric leukemia risk. This equalizing differential is estimated using property-level sales records from a county in Nevada where residents have recently experienced a severe increase in pediatric leukemia. Housing values are compared before and after the increase with a nearby county acting as a control group. The results indicate that housing values decreased 15.6% during the period of maximum risk. Results are similar for alternative measures of risk and across houses of different sizes. With risk estimates derived using a Bayesian learning model the results imply a statistical value of pediatric leukemia of $5.6 million. The results from the paper provide some of the first market-based estimates of the value of health for children. The second essay evaluates the cost-effectiveness of public incentives that encourage households to purchase high-efficiency durable goods. The demand for durable goods and the demand for energy and other inputs are modeled jointly as the solution to a household production problem. The empirical analysis focuses on the case of clothes washers. The production technology and utilization decision are estimated using household-level data from field trials in which participants received front-loading clothes washers free of charge. The estimation strategy exploits this quasi-random replacement of washers to derive robust estimates of the utilization decision. The results indicate a price elasticity, -.06, that is statistically different from zero across specifications. The parameters from the utilization decision are used to estimate the purchase decision using data from the Consumer Expenditure Survey, 1994-2002. Households

    Anecdotal reports suggest that some residency application essays contain plagiarized content. To determine the prevalence of plagiarism in a large cohort of residency application essays. Retrospective cohort study. 4975 application essays submitted to residency programs at a single large academic medical center between 1 September 2005 and 22 March 2007. Specialized software was used to compare residency application essays with a database of Internet pages, published works, and previously submitted essays and the percentage of the submission matching another source was calculated. A match of more than 10% to an existing work was defined as evidence of plagiarism. Evidence of plagiarism was found in 5.2% (95% CI, 4.6% to 5.9%) of essays. The essays of non-U.S. citizens were more likely to demonstrate evidence of plagiarism. Other characteristics associated with the prevalence of plagiarism included medical school location outside the United States and Canada; previous residency or fellowship; lack of research experience, volunteer experience, or publications; a low United States Medical Licensing Examination Step 1 score; and non-membership in the Alpha Omega Alpha Honor Medical Society. The software database is probably incomplete, the 10%-match threshold for defining plagiarism has not been statistically validated, and the study was confined to applicants to 1 institution. Evidence of matching content in an essay cannot be used to infer the applicant's intent and is not sensitive to variations in the cultural context of copying in some societies. Evidence of plagiarism in residency application essays is more common in international applicants but was found in those by applicants to all specialty programs, from all medical school types, and even among applicants with significant academic honors.

    Better reproducibility of networking research results is currently a major goal that the academic community is striving towards. This position paper makes the case that improving the extent and pervasiveness of reproducible research can be greatly fostered by organizing a yearly international contest. We argue that holding a contest undertaken by a plurality of students will have benefits that are two-fold. First, it will promote hands-on learning of skills that are helpful in producing artifacts at the replicable-research level. Second, it will advance the best practices regarding environments, testbeds, and tools that will aid the tasks of reproducibility evaluation committees by and large.

  5. Holiday Door Decorating Contest Brings Cheer | Poster

    Science.gov (United States)

    By Carolynne Keenan, Contributing Writer Other than the time of year, what do the following have in common: the leg lamp from the movie “A Christmas Story,” a compilation of silly holiday jokes, a gingerbread house, and Santa on a motorcycle? All four were among the individual door winners for the Holiday Door Decorating Contest, held at NCI at Frederick in December. Employees dressed up their office doors, hallways, and even stairwells to participate. Entries for the contest included individual office doors as well as groups. Some employees even “decked the halls” of whole office buildings to participate.

  7. Olivier's 'Essay on Hamlet'

    Directory of Open Access Journals (Sweden)

    Koprivica Zoran

    2017-01-01

    Full Text Available Laurence Olivier's Hamlet is more a renaissance character, a melancholic and a daydreamer, than a man of action, unlike his Henry V and Richard III film adaptations. However, it seems that Olivier showed outstanding courage not in his extremely liberal approach to interpreting this Shakespeare's tragedy, but in literal application of Freud's model on his inner problems, seen through the prism of the professor Ernest Johnson. Transposing Shakespeare's original text, starting with its global features, he abstracts numerous and diversified eventful and associative moments which might burden the polyphonic structure of his own - film story. Moreover, Olivier wants to avoid its dramatic deconstruction and focuses the viewer's attention to the climactic moments. However, dramatically the strongest and most effective scenes in his film adaptation of Hamlet are the ones related to the use of camera, that is to say, its movement and analyticity. The intention was to point not only to the ostentatious difference between cinematographic and theatrical stylisation, but, to a certain extent, he defines the viewer's standpoint. In his 'essay on Hamlet', Olivier does not consider chronology, that is to say, the problem of temporal relations. The visual structure of the film and its dynamics are determined a priori by the rhythmic parameters of the Elsinore's labyrinthic space.

  8. Review Essay: Controlled Openness

    Directory of Open Access Journals (Sweden)

    Andreas Wenninger

    2008-08-01

    Full Text Available The book reviewed here contains a written form of Niklas LUHMANN’s last lecture, delivered in winter term 1992/1993 at Bielefeld University, where he was professor for sociology from 1968 to 1993. A more comprehensive and systematic publication titled "Die Gesellschaft der Gesellschaft" was not published until 1997. In comparison to this and to other publications the present one provides an insight into the modality of the theoretical practice of LUHMANN. My review-essay follows up that point and reminds us that LUHMANN worked out his theory of society in view of a sociological problem he had conceived. He accused sociology of accumulating knowledge in a confusing way by empirical social research. His endeavour, in contrast, was to enable research within a consistent theoretical frame that was nevertheless open to expansive explorations. LUHMANN tries to achieve consistency through the reciprocal adjustment of his terms and his theoretical components, which should enable the construction of problems for comparison within global society. This means that his approach stays open for an empirical reality that remains to be explored because the theory of society does not deliver terms to categorize empirical reality. Instead, terms are conceptualized as distinctions with the function to construct problems that instruct observations and make them amenable to theorization. URN: urn:nbn:de:0114-fqs0803237

  9. Rhombencephalitis: pictorial essay

    Directory of Open Access Journals (Sweden)

    Líllian Gonçalves Campos

    Full Text Available Abstract The term rhombencephalitis refers to inflammatory diseases affecting the hindbrain (brainstem and cerebellum. Rhombencephalitis has a wide variety of etiologies, including infections, autoimmune diseases, and paraneoplastic syndromes. Infection with bacteria of the genus Listeria is the most common cause of rhombencephalitis. Primary rhombencephalitis caused by infection with Listeria spp. occurs in healthy young adults. It usually has a biphasic time course with a flu-like syndrome, followed by brainstem dysfunction; 75% of patients have cerebrospinal fluid pleocytosis, and nearly 100% have an abnormal brain magnetic resonance imaging scan. However, other possible causes of rhombencephalitis must be borne in mind. In addition to the clinical aspects, the patterns seen in magnetic resonance imaging can be helpful in defining the possible cause. Some of the reported causes of rhombencephalitis are potentially severe and life threatening; therefore, an accurate initial diagnostic approach is important to establishing a proper early treatment regimen. This pictorial essay reviews the various causes of rhombencephalitis and the corresponding magnetic resonance imaging findings, by describing illustrative confirmed cases.

  13. UV-green iridescence predicts male quality during jumping spider contests.

    Science.gov (United States)

    Lim, Matthew L M; Li, Daiqin

    2013-01-01

    Animal colour signals used in intraspecies communications can generally be attributed to a composite effect of structural and pigmentary colours. Notably, the functional role of iridescent coloration that is 'purely' structural (i.e., absence of pigments) is poorly understood. Recent studies reveal that iridescent colorations can reliably indicate individual quality, but evidence of iridescence as a pure structural coloration indicative of male quality during contests and relating to an individual's resource-holding potential (RHP) is lacking. In age- and size-controlled pairwise male-male contests that escalate from visual displays of aggression to more costly physical fights, we demonstrate that the ultraviolet-green iridescence of Cosmophasis umbratica predicts individual persistence and relates to RHP. Contest initiating males exhibited significantly narrower carapace band separation (i.e., relative spectral positions of UV and green hues) than non-initiators. Asymmetries in carapace and abdomen brightness influenced overall contest duration and escalation. As losers retreated upon having reached their own persistence limits in contests that escalated to physical fights, losers with narrower carapace band separation were significantly more persistence. We propose that the carapace UV-green iridescence of C. umbratica predicts individual persistence and is indicative of a male's RHP. As the observed UV-green hues of C. umbratica are 'pure' optical products of a multilayer reflector system, we suggest that intrasexual variations in the optical properties of the scales' chitin-air-chitin microstructures are responsible for the observed differences in carapace band separations.

    Contests can engage, motivate, instruct and inspire students of all grade levels and interests. What are the ingredients necessary for a successful science contest? The Institute for Global Environmental Strategies (IGES) has recommendations for designing science-based competitions that are both fun and educational for for elementary and secondary students. These recommendations were developed as a result of IGES' experience gained through two annual student competitions that focus on Earth science topics: An annual art contest, for grades 2-4, challenges U.S. students to explore a specific Earth science topic. For example, past themes have included Polar Explorations: Going to Extremes (2006); Connect-4: Air, Land, Water, and Life (2005); and Picture Me: What Kind of Earth Explorer Would I Be? (2004). The contest supports national science education standards for grades K-4, and includes suggested classroom activities, books, and movies. The Thacher Scholarship was founded in 2000 by IGES in honor of the late Peter S. Thacher, a former IGES board member and leader in promoting the use of satellite remote sensing. The $4,000 scholarship is awarded to exceptional high school students displaying the best use of satellite remote sensing in understanding our changing planet.

    2014-07-01

    Here we present the results of the 6th biennial optical interferometry imaging beauty contest. Taking advantage of a unique opportunity, the red supergiant VY CMa and the Mira variable R Car were observed in the astronomical H-band with three 4-telescope configurations of the VLTI-AT array using the PIONIER instrument. The community was invited to participate in the subsequent image reconstruction and interpretation phases of the project. Ten groups submitted entries to the beauty contest, and we found reasonable consistency between images obtained from independent workers using quite different algorithms. We also found that significant differences existed between the submitted images, much greater than in past beauty contests that were all based on simulated data. A novel crowd-sourcing" method allowed consensus median images to be constructed, filtering likely artifacts and retaining real features." We definitively detect strong spots on the surfaces of both stars as well as distinct circumstellar shells of emission (likely water/CO) around R Car. In a close contest, Joel Sanchez (IAA-CSIC/Spain) was named the winner of the 2014 interferometric imaging beauty contest. This process has shown that new comers" can use publicly-available imaging software to interpret VLTI/PIONIER imaging data, as long as sufficient observations are taken to have complete uv coverage { a luxury that is often missing. We urge proposers to request adequate observing nights to collect sufficient data for imaging and for time allocation committees to recognise the importance of uv coverage for reliable interpretation of interferometric data. We believe that the result of the proposed broad international project will contribute to inspiring trust in the image reconstruction processes in optical interferometry.

  9. Contests versus Norms: Implications of Contest-Based and Norm-Based Intervention Techniques.

    2017-01-01

    Interventions using either contests or norms can promote environmental behavioral change. Yet research on the implications of contest-based and norm-based interventions is lacking. Based on Goal-framing theory, we suggest that a contest-based intervention frames a gain goal promoting intensive but instrumental behavioral engagement. In contrast, the norm-based intervention was expected to frame a normative goal activating normative obligations for targeted and non-targeted behavior and motivation to engage in pro-environmental behaviors in the future. In two studies participants ( n = 347) were randomly assigned to either a contest- or a norm-based intervention technique. Participants in the contest showed more intensive engagement in both studies. Participants in the norm-based intervention tended to report higher intentions for future energy conservation (Study 1) and higher personal norms for non-targeted pro-environmental behaviors (Study 2). These findings suggest that contest-based intervention technique frames a gain goal, while norm-based intervention frames a normative goal.

  11. Essays in Applied Microeconomics

    Science.gov (United States)

    Ge, Qi

    This dissertation consists of three self-contained applied microeconomics essays on topics related to behavioral economics and industrial organization. Chapter 1 studies how sentiment as a result of sports event outcomes affects consumers' tipping behavior in the presence of social norms. I formulate a model of tipping behavior that captures consumer sentiment following a reference-dependent preference framework and empirically test its relevance using the game outcomes of the NBA and the trip and tipping data on New York City taxicabs. While I find that consumers' tipping behavior responds to unexpected wins and losses of their home team, particularly in close game outcomes, I do not find evidence for loss aversion. Coupled with the findings on default tipping, my empirical results on the asymmetric tipping responses suggest that while social norms may dominate loss aversion, affect and surprises can result in freedom on the upside of tipping. Chapter 2 utilizes a novel data source of airline entry and exit announcements and examines how the incumbent airlines adjust quality provisions as a response to their competitors' announcements and the role of timing in such responses. I find no evidence that the incumbents engage in preemptive actions when facing probable entry and exit threats as signaled by the competitors' announcements in either short term or long term. There is, however, evidence supporting their responses to the competitors' realized entry or exit. My empirical findings underscore the role of timing in determining preemptive actions and suggest that previous studies may have overestimated how the incumbent airlines respond to entry threats. Chapter 3, which is collaborated with Benjamin Ho, investigates the habit formation of consumers' thermostat setting behavior, an often implicitly made decision and yet a key determinant of home energy consumption and expenditures. We utilize a high frequency dataset on household thermostat usage and find that

  12. Essays in public economics

    Science.gov (United States)

    Seligman, Jason Scott

    2002-01-01

    Three essays in the field of public economics are included in this thesis. Chapter 1 begins this work with an introduction to public economics and places the remaining chapters in context. Like all economic agents, the government must manage its cash position. Chapter 2 considers this activity. Short-term financial requirements cause the government to solicit the market for bills not previously scheduled (Cash Management Bills). Using data from the US Treasury's Proprietary Domestic Finance Database, this chapter shows that these bills have higher costs than normal bills, suggesting that both Treasury and financial markets appreciate that demand is more inelastic for these instruments. In addition, this research identifies several factors that increase finance costs for Treasury in meeting short-term financial need. Chapter 3 explores location choices for generation investment in a re-regulated electricity market. Recently, there have been significant changes in the regulation of electricity in the State of California. These changes may affect generation investment behavior within the State, an important consideration for policy makers. This work identifies the impact of public sector regulatory change on private sector investment outcomes, by comparing the location and scope of electricity generation projects before and after two specific regulatory changes in air quality management and transmission tariff charges, while controlling for expected population growth patterns within the State. Significant changes in location preference are identified using factors for the northern and southern transmission zones, NP15 and SP15, the intermediate zone ZP26, and for areas outside of ISO control. Chapter 4 considers Disability Insurance and individual public pension investment accounts. Current debate on the Social Security Administration's long-term finance of benefits includes proposals for independent private investment via individual accounts. The author investigates

    Existing literature on the City of London has tended to focus on its ‘structural power’, while neglecting political and narrative agency. This paper acts as a corrective by presenting evidence to show that since the financial crash of 2008 the political terrain the City operates on has become more...... contested, crowded and noisier. The contribution develops a middle course between a positive assessment of the role of civil society in relation to global finance, and a more pessimistic reading. We demonstrate how macro-narratives and public story-telling both construct and contest City and financial...... sector power. In a new pattern since the financial crash, NGOs have moved from campaigns of limited duration and narrow focus, to a more sustained presence on macro-structural issues. Adopting a supply–demand framework for assessing governance and regulatory change, we look at the emergence of TheCity...

    The purpose of this study was to document the physiological changes that occur in a natural bodybuilder during prolonged contest preparation for a proqualifying contest. During the 26-week preparation, the athlete undertook a calorically restrictive diet with 2 days of elevated carbohydrate intake per week, increased cardiovascular (CV) training, and attempted to maintain resistance-training load. The athlete was weighed twice a week and body composition was measured monthly by DXA. At baseline and every 2 weeks following CV structure and function was measured using a combination of ultrasound, applanation tonometry, and heart rate variability (HRV). Cardiorespiratory performance was measured by VO(2)peak at baseline, 13 weeks, and 26 weeks. Body weight (88.6 to 73.3 Kg, R(2) = .99) and percent body fat (17.5 to 7.4%) were reduced during preparation. CV measurements including blood pressure (128/61 to 113/54 mmHg), brachial pulse wave velocity (7.9 to 5.8m/s), and measures of wave reflection all improved. Indexed cardiac output was reduced (2.5 to 1.8L/m(2)) primarily due to a reduction in resting heart rate (71 to 44 bpm), and despite an increase in ejection faction (57.9 to 63.9%). Assessment of HRV found a shift in the ratio of low to high frequency (209.2 to 30.9%). Absolute VO2 was minimally reduced despite weight loss resulting in an increase in relative VO2 (41.9 to 47.7 ml/Kg). In general, this prolonged contest preparation technique helped the athlete to improve body composition and resulted in positive CV changes, suggesting that this method of contest preparation appears to be effective in natural male bodybuilders.

    Abstract: Working with a range of material (objects, ephemera, texts characteristic of a scrapbook, Carson & Miller will produce a visual essay that investigates the experience of reading such matter in this often underrated and undervalued form. In this context the notion of reading (and, subsequently re-reading and mis-reading will be utilised to explore the construction of narrative and the manner in which such narratives can present misleading, misinterpreted or inaccurate accounts of ‘things’. In doing so, such accounts can produce a multiplicity of new narratives.

                To develop this idea visually Carson & Miller will harness the tradition and format of a scrapbook. Scrapbooks imply the creative use of material which would be valued differently (or indeed undervalued in other contexts; the inclusion of scraps in the scrapbook claims that which is defined as ‘scrap’ as valuable and worthy of possession. In essence a scrapbook brings together disparate material and is often constructed according to its own internal ordering and logic; sometimes things are related by type, sometimes unlikely objects are combined or juxtaposed in fortuitous encounters. Such fortuitous encounters tell their own stories but also produce new narratives through generating new combinations of significance (Allmer iv.

    Full Text Available This paper posits the idea that the theme of agency in architecture is parallactic. It discusses the tectonic as an agent through which architecture turns into a state of constant flux. The intention is to promote a discourse of criticality, the thematic of which is drawn from the symptoms that galvanise architecture’s rapport with the image-laden culture of late capitalism. In an attempt to log the thematic of a contested practice, this essay will re-map the recent history of contemporary architecture.Exploring New Brutalism’s criticism of the established ethos of International Style architecture, the first part of this paper will highlight the movement’s tendency towards replacing the painterly with the sculptural, and this in reference to the contemporary interest in monolithic architecture. Having established the import of tectonics for the architecture of Brutalism, the paper then argues that in the present situation, when architecture – like other cultural products – is infatuated with the spectacle of late capitalism, a re-thinking of the Semperian notion of theatricality is useful. Of interest in the tectonic of theatricality is the work’s capacity to bring forth the division between intellectual and physical labours, and this in reference to architecture’s reserved acceptance of technification for which the aforementioned division is vital.Particular attention will be given to two projects, Zaha Hadid’s Phaeno Center and OMA’s Casa da Musica, where architectonic aspects of New Brutalism are revisited in the light of the tectonic of theatricality.

  6. Empirical essays on energy economics

    2013-06-13

    The main part of this thesis consists of three distinct essays that empirically analyze economic issues related to energy markets in the United States and Europe. The first chapter provides an introduction and discusses the motivation for the different analyses pursued in this thesis. The second chapter examines attention effects in the market for hybrid vehicles. We show that local media coverage, gasoline price changes and unprecedented record gasoline prices have a significant impact on the consumers' attention. As attention is not directly observable, we analyze online search behavior as a proxy for the revealed consumer attention. Our study is based on a unique weekly panel dataset for 19 metropolitan areas in the US. Additionally, we use monthly state-level panel data to show that the adoption rate of hybrid vehicles is robustly related to our measure of attention. Our results show that the consumers' attention fluctuates strongly and systematically. The third chapter shows how the effect of fuel prices varies with the level of electricity demand. It analyzes the relationship between daily prices of electricity, natural gas and carbon emission allowances with a semiparametric varying smooth coefficient cointegration model. This model is used to analyze the market impact of the nuclear moratorium by the German Government in March 2011. Futures prices of electricity, natural gas and emission allowances are used to show that the market efficiently accounts for the suspended capacity and correctly expects that several nuclear plants will not be switched on after the moratorium. In the fourth chapter, we develop a structural vector autoregressive model (VAR) for the German natural gas market. In particular, we illustrate the usefulness of our approach by disentangling the effects of different fundamental influences during four specific events: The financial crisis starting in 2008, the Russian-Ukrainian gas dispute in January 2009, the Libyan civil war

    2003-07-01

    This thesis consists of four essays that aim at contributing to the understanding of some of the new challenges associated by the liberalized energy markets. More specifically the essays consider investments in energy generation projects; international trade of Green Certificates, market power in a Green Certificate system, and finally the behaviour of public firms in liberalized markets. Essay 1 considers energy investment, when a choice has to be made between fossil fuel and biomass fired production technologies. A dynamic model is presented to illustrate the effect of the different degrees of input price uncertainty on the choice of technology and the timing of the investment. It is shown that when the choice of technology is irreversible, it may be optimal to postpone the investment even if it would otherwise be optimal to invest in one or both of the plant types. We provide a numerical example based on cost estimates of two different power plant types. Essay 2 presents an analytical equilibrium model for simultaneously functioning international markets for electricity and Green Certificates is formulated. The percentage requirement is perceived as the policy instrument affecting the level of green electricity in end-use consumption. In none of the cases considered does an increase in the country's percentage requirement necessarily result in an increase in the generation of green electricity in that country, but it may have a positive effect on the trading partner's generation of green electricity. Further, under quite realistic assumptions, a country maximizes its generation of green electricity by setting the percentage requirement to zero. In essay 3 an analytic equilibrium model for a simultaneously functioning electricity market and a market for Green Certificates is formulated. The major focus of the paper is the effect of market power in a Green Certificate system. One of the main results is that the certificate system faced with market power

  15. Psychology: red enhances human performance in contests.

    Science.gov (United States)

    Hill, Russell A; Barton, Robert A

    2005-05-19

    Red coloration is a sexually selected, testosterone-dependent signal of male quality in a variety of animals, and in some non-human species a male's dominance can be experimentally increased by attaching artificial red stimuli. Here we show that a similar effect can influence the outcome of physical contests in humans--across a range of sports, we find that wearing red is consistently associated with a higher probability of winning. These results indicate not only that sexual selection may have influenced the evolution of human response to colours, but also that the colour of sportswear needs to be taken into account to ensure a level playing field in sport.

The factors which caused consisted of political of education, state policies, and socio-cultural. The implications of this research were (1 There was shifting of educational values into capitalism, (2 The meaning of learning became limited in which it was just purposed at facing National Examination, (3 Educational services have shifted from humanist public services to commodification of education, with the result that honesty was marginalized. Eventhough the government has developed sophisticated system and very tight supervision, if the character of the subjects are not formed and cultured, accordingly, the National Examination stated honest and achievement oriented will be just a slogan. Therefore, the education system needs to be improved. The education paradigm which is more emphasized on the increasing of intellectual intelligence by multiple choice tests and scores needs to be deconstructed by adjusting with Indonesian cultural values based on “Pancasila” as ideological foundation and developing character education to the children from early age.

  1. Contested Boundaries: psychiatry, disease, and diagnosis.

    Science.gov (United States)

    Rosenberg, Charles E

    2015-01-01

    Since the 19th century, we have come to think of disease in terms of specific entities--entities defined and legitimated in terms of characteristic somatic mechanisms. Since the last third of that century, we have expanded would-be disease categories to include an ever-broader variety of emotional pain, idiosyncrasy, and culturally unsettling behaviors. Psychiatry has been the residuary legatee of these developments, developments that have always been contested at the ever-shifting boundary between disease and deviance, feeling and symptom, the random and the determined, the stigmatized and the value-free. Even in our era of reductionist hopes, psychopharmaceutical practice, and corporate strategies, the legitimacy of many putative disease categories will remain contested. The use of the specific disease entity model will always be a reductionist means to achieve necessarily holistic ends, both in terms of cultural norms and the needs of suffering individuals. Bureaucratic rigidities and stakeholder conflicts structure and intensify such boundary conflicts, as do the interests and activism of an interested lay public.

  2. Self-sacrifice in 'desperado' contests between relatives

    Directory of Open Access Journals (Sweden)

    Monnin Thibaud

    2010-10-01

    Full Text Available Abstract Intra-specific competition occurs in all animal species and can lead to escalated conflict. Overt fighting entails the risk of injury or death, and is usually avoided through the use of conventions or pre-fight assessments. However, overt fighting can be expected when value of the contest outweighs the value of the future, as contestants have little or nothing to lose. In these situations, respect for conventions and asymmetries between contestants can break down, and overt fighting becomes more likely (the desperado effect. Such conditions can arise in contests between queens over colony ownership in social insects, because the value of inheriting a colony of potentially thousands of helpers is huge and queens may have very limited alternative reproductive options. However, in social species the balance of possible outcomes may be influenced by inclusive fitness, as contestants are often relatives. Here we present a simple model based on social insects, which demonstrates that not fighting can be selectively advantageous when there is a risk posed by fighting to inclusive fitness, even when not fighting is likely to result in death. If contestants are related, a loser can still gain indirect fitness through the winner, whereas fighting introduces a risk that both queens will die and thereby obtain zero inclusive fitness. When relatedness is high and fighting poses a risk of all contestants dying, it can be advantageous to cede the contest and be killed, rather than risk everything by fighting.

  11. Using contests to allocate pollution rights

    International Nuclear Information System (INIS)

    MacKenzie, Ian A.; Hanley, Nick; Kornienko, Tatiana

    2009-01-01

    In this paper we advocate a new initial allocation mechanism for a tradable pollution permit market. We outline a Permit Allocation Contest (PAC) that distributes permits to firms based on their rank relative to other firms. This ranking is achieved by ordering firms based on an observable 'external action' where the external action is an activity or characteristic of the firm that is independent of their choice of emissions in the tradable permit market. We argue that this mechanism has a number of benefits over auctioning and grandfathering. Using this mechanism efficiently distributes permits, allows for the attainment of a secondary policy objective and has the potential to be more politically appealing than existing alternatives.

  12. The Indian IVF saga: a contested history

    Directory of Open Access Journals (Sweden)

    Aditya Bharadwaj

    2016-06-01

    Full Text Available The politics of conception in India can be traced back to the birth of the world’s first test-tube baby in 1978. This article focuses on an incident where scientists and clinicians were involved in a heated contest over ascription of intellectual credit for the birth of the first test-tube baby in India. It traces the controversy surrounding claims and counter-claims within the medical domain that appear to have emerged as a corollary to the rapid expansion of assisted conception in India. The article emphasizes the fact that this contentious issue played out largely in the media and shows that the generation of scientific credibility and reward is produced and ascribed both inside and outside the scientific domain. In so doing the article offers a glimpse into the unique ability of cultural activity to shape and recast the perception of science and scientific outcomes.

  14. The role of male contest competition over mates in speciation

    Directory of Open Access Journals (Sweden)

    Anna QVARNSTRÖM, Niclas VALLIN, Andreas RUDH

    2012-06-01

    Full Text Available Research on the role of sexual selection in the speciation process largely focuses on the diversifying role of mate choice. In particular, much attention has been drawn to the fact that population divergence in mate choice and in the male traits subject to choice directly can lead to assortative mating. However, male contest competition over mates also constitutes an important mechanism of sexual selection. We review recent empirical studies and argue that sexual selection through male contest competition can affect speciation in ways other than mate choice. For example, biases in aggression towards similar competitors can lead to disruptive and negative frequency-dependent selection on the traits used in contest competition in a similar way as competition for other types of limited resources. Moreover, male contest abilities often trade-off against other abilities such as parasite resistance, protection against predators and general stress tolerance. Populations experiencing different ecological conditions should therefore quickly diverge non-randomly in a number of traits including male contest abilities. In resource based breeding systems, a feedback loop between competitive ability and habitat use may lead to further population divergence. We discuss how population divergence in traits used in male contest competition can lead to the build up of reproductive isolation through a number of different pathways. Our main conclusion is that the role of male contest competition in speciation remains largely scientifically unexplored [Current Zoology 58 (3: 490–506, 2012].

  17. Animal personality as a cause and consequence of contest behaviour.

    Science.gov (United States)

    Briffa, Mark; Sneddon, Lynne U; Wilson, Alastair J

    2015-03-01

    We review the evidence for a link between consistent among-individual variation in behaviour (animal personality) and the ability to win contests over limited resources. Explorative and bold behaviours often covary with contest behaviour and outcome, although there is evidence that the structure of these 'behavioural syndromes' can change across situations. Aggression itself is typically repeatable, but also subject to high within-individual variation as a consequence of plastic responses to previous fight outcomes and opponent traits. Common proximate mechanisms (gene expression, endocrine control and metabolic rates) may underpin variation in both contest behaviour and general personality traits. Given the theoretical links between the evolution of fighting and of personality, we suggest that longitudinal studies of contest behaviour, combining behavioural and physiological data, would be a useful context for the study of animal personalities. © 2015 The Author(s) Published by the Royal Society.

    Rowe, Candy; Harris, Julie M; Roberts, S Craig

    2005-10-27

    The shirt colour worn by sportsmen can affect the behaviour of the competitors, but Hill and Barton show that it may also influence the outcome of contests. By analysing the results of men's combat sports from the Athens 2004 Olympics, they found that more matches were won by fighters wearing red outfits than by those wearing blue; they suggest that red might confer success because it is a sign of dominance in many animal species and could signal aggression in human contests. Here we use another data set from the 2004 Olympics to show that similar winning biases occur in contests in which neither contestant wears red, indicating that a different mechanism may be responsible for these effects.

    1992-01-01

    The Waste-management Education and Research Consortium (WERC) of New Mexico has developed and implemented an environmental design contest for competition by universities throughout America. This is the first university environmental design contest anywhere in the world. WERC is a consortium of three universities, a community college, and two national laboratories sponsored by the DOE with the mission of generating resources to address issues associated with environmental management. The contest was structured to give university student groups from all over America an opportunity to exchange information via a national contest for design, development, and testing of an environmental control process. A practical environmental problem was presented to the competing teams. Each team prepared a total plant design for the solution of the environmental problem. They further prepared a working model to demonstrate each solution on a smaller scale. The design stressed not just the technical solution, but also such factors as economics, risk analysis, regulations, public policy and communications. The judging was preformed by experts from academia, industry and government agencies. The awards were based on the written plant design, the small demonstration, as well as presentations by the competing teams. All the criteria noted above(technical excellence, risk analysis, etc.) were weighted in the judging. Seven universities from throughout the United States competed in the first contest held in April 1991. The program fully accomplished its objective of providing a design challenge as well as providing a medium of exchanging information in the environmental area between various regions of the country. Over twenty universities have signed up to compete in next year's contest. In fact many have used the contest problem as part of their capstone design course. This paper presents the experiences of the first design contest and the topic for the second year. (author)

    2009-05-01

    The contest ``Space Baptism 2007'' was organized with the cooperation of the Mirador de la Ciencia, a science museum associated with the local zoo in Barquisimeto, Venezuela, and in collaboration with the Asociación Larense de Astronomía, a local astronomy amateur group. This contest was aimed at students of primary schools and had as a final award the chance to give a proper name to an asteroid. The ultimate goal of the contest was to promote basic and space sciences to children and the young through activities that involved the creation of stories related to astronomy, enforcing creativity and originality, and encouraging group work and solidarity. As a result, the asteroid (12758) 1993 SM3 will be known from now on as (12758) Kabudarí. The success of this initiative is demonstrated by stories about the contest that appeared in several publications in local newspapers and magazines about the school and the students who won the contest. We are currently developing plans for repetitions of the contest to name two more asteroids.

The article is focused as a Critical Discourse Analysis that compares the language use in news articles from The New York Times and The Wall Street Journal over a six months period in order to more clearly understand the way the news media uses language in regards to gender and sexual assault and creates a spectrum of valid versus contested reports of sexual assault in different cultural settings.

  15. Individual performance and leader's laterality in interactive contests.

    Mukherjee, Satyam

    2017-05-01

    Left-handedness is known to provide an intrinsic and tactical advantage at top level in many sports involving interactive contests. Again, most of the renowned leaders of the world are known to have been left-handed. Leadership plays an important role in politics, sports and mentorship. In this paper we show that Cricket captains who bat left-handed have a strategic advantage over the right-handed captains in One Day International (ODI) and Test matches. The present study involving 46 left-handed captains and 148 right-handed captains in ODI matches, reveal a strong relation between leader's laterality and team member performance, demonstrating the critical importance of left-handedness and successful leadership. The odds for superior batting performance in an ODI match under left-handed captains are 89% higher than the odds under right-handed captains. Our study shows that left-handed captains are more successful in extracting superior performance from the batsmen and bowlers in ODI and Test matches; perhaps indicating left-handed leaders are better motivators as leaders when compared to right-handed captains.

    2015-10-01

    Full Text Available This paper aims to problematize how we step into situations that are often contested, contingent and contradictory. In this context, how can we sharpen our sensitivity of the role design plays in generating understanding and future-making possibilities? Here, we employ the term disruption as a way to question our own knowledge construction and research practices in Design Anthropology and Participatory Design. We pursue disruption as a political and necessary consciousness when Design Anthropology meets Participatory Design and discuss the generative, reflexive and analytical dimensions of disruption through three vignettes. These vignettes raises questions of how we interrogate disruptions of power to consider different ways in which this manifests when entering into and participating in ongoing changing process. They also highlight the need to displace existing knowledge, rather than pursuing ‘mutual learning’ that had been a defining commitment of Participatory Design. Lastly, the vignettes reveal the need to disrupt the designer-researcher in order to surrender to contradiction and contingency as part of future-making.

  17. Contested understandings of recovery in mental health.

    Science.gov (United States)

    McCabe, Rhiannah; Whittington, Richard; Cramond, Laura; Perkins, Elizabeth

    2018-05-17

    The concept of recovery is contested throughout the existing literature and in mental health services. Little research exists that gives voice to service user perspectives of recovery. This paper explores how service users in two recovery oriented services run by the National Health Service in North West England talked about recovery and what it meant to them. 14 service users accessing these services took part in semi-structured qualitative interviews focusing on the concept of recovery. Data were analysed using an interpretive phenomenological analysis approach. Service users talked about recovery as a dynamic, day to day process as well as an outcome; specifically related to being discharged from inpatient settings. A number of factors including relationships and medication were cited to have the potential to make or break recovery. The study highlights the continued dominance of the biomedical model in mental health services. Service users appear to have internalised staff and services' understanding of recovery perhaps unsurprisingly given the power differential in these relationships. Implications for clinical practice are explored.

  18. Contested psychiatric ontology and feminist critique

    Science.gov (United States)

    Angel, Katherine

    2012-01-01

    In this article I discuss the emergence of Female Sexual Dysfunction (FSD) within American psychiatry and beyond in the postwar period, setting out what I believe to be important and suggestive questions neglected in existing scholarship. Tracing the nomenclature within successive editions of the American Psychiatric Association’s Diagnostic and Statistical Manual (DSM), I consider the reification of the term ‘FSD’, and the activism and scholarship that the rise of the category has occasioned. I suggest that analysis of FSD benefits from scrutiny of a wider range of sources (especially since the popular and scientific cross-pollinate). I explore the multiplicity of FSD that emerges when one examines this wider range, but I also underscore a reinscribing of anxieties about psychogenic aetiologies. I then argue that what makes the FSD case additionally interesting, over and above other conditions with a contested status, is the historically complex relationship between psychiatry and feminism that is at work in contemporary debates. I suggest that existing literature on FSD has not yet posed some of the most important and salient questions at stake in writing about women’s sexual problems in this period, and can only do this when the relationship between ‘second-wave’ feminism, ‘post-feminism’, psychiatry and psychoanalysis becomes part of the terrain to be analysed, rather than the medium through which analysis is conducted.

  19. Three essays on access pricing

    Science.gov (United States)

    Sydee, Ahmed Nasim

    In the first essay, a theoretical model is developed to determine the time path of optimal access price in the telecommunications industry. Determining the optimal access price is an important issue in the economics of telecommunications. Setting a high access price discourages potential entrants; a low access price, on the other hand, amounts to confiscation of private property because the infrastructure already built by the incumbent is sunk. Furthermore, a low access price does not give the incumbent incentives to maintain the current network and to invest in new infrastructures. Much of the existing literature on access pricing suffers either from the limitations of a static framework or from the assumption that all costs are avoidable. The telecommunications industry is subject to high stranded costs and, therefore, to address this issue a dynamic model is imperative. This essay presents a dynamic model of one-way access pricing in which the compensation involved in deregulatory taking is formalized and then analyzed. The short run adjustment after deregulatory taking has occurred is carried out and discussed. The long run equilibrium is also analyzed. A time path for the Ramsey price is shown as the correct dynamic price of access. In the second essay, a theoretical model is developed to determine the time path of optimal access price for an infrastructure that is characterized by congestion and lumpy investment. Much of the theoretical literature on access pricing of infrastructure prescribes that the access price be set at the marginal cost of the infrastructure. In proposing this rule of access pricing, the conventional analysis assumes that infrastructure investments are infinitely divisible so that it makes sense to talk about the marginal cost of investment. Often it is the case that investments in infrastructure are lumpy and can only be made in large chunks, and this renders the marginal cost concept meaningless. In this essay, we formalize a model of

  20. Rethinking Eurovision Song Contest as a Clash of Cultures

    Directory of Open Access Journals (Sweden)

    Zeynep Merve ŞIVGIN

    2015-12-01

    Full Text Available Modern era’s understanding of culture overlooked culture, as a social and cultural analysis category as well as a way of life. This point of view has lost its validity and culture gained significance as an area where rulership and power struggle exists. Especially the privileged existence of popular culture; having an interdependence attachment to power relations in addition to an allowing structure for alternative discourses other than the official discourse is a cruicial asset. This article examines Eurovision Song Contest with its over 50 years of traditionaled history, as a noteworthy television program of popular culture. Despite often being considered as “kitsch”, the contest refers more than of an ordinary song competition. The artists who participate in the contest compete for the country they represent rather than an individual race which takes “national identity” more on stage. In this respect the contest has a stimulus effect on national consciousness. This alerted effect can clearly be seen on public debates just before, during and after the contest. It is claimed in this study that Turkey’s position in Eurovision Song Contest offers a view of the “cultural struggle” towards Western civilization since the beginning of the modernization process. In this framework this study primarily focuses on the relationship between identity and culture, followed by the role of popular culture in the construction of cultural identity. Afterwards the study tries to discover how does this contest became a tool of cultural struggle in Turkish society by analyzing the news and the discource of the news that took place in national print media.

    2016-10-01

    Full Text Available The article presents the first Russian translation of "Essay on Ci" with detailed comments. It was written by the outstanding Chinese poetess Li Qingzhao and considered to be the first theoretical treatise dedicated to genre ci. The article revealed that the poetess used three strategies to make a genre demarcation: to legitimise, dichotomise and historicise. To legitimise means to justify that ci is a genre of poetry by identifying the same traits with official poetry shi (e.g. using the classical quotations and allusions. To dichotomise is to determine a core element of genre and oppose it to the other element identifying the similar genre (e.g. music separates ci from shi. To historicise is to develop or discover the unique historical past (e.g. the source of ci is in antiquity. The article also examined the strategy to invent classics: Li Qingzhao wrote the apophatic history of genre ci pointing not to the merits but weaknesses of her predecessors.

  8. Three essays on utility regulation

    Science.gov (United States)

    Hlasny, Vladimir

    To induce utilities in the gas distribution market to operate efficiently, US states have deployed consumer choice programs, price caps, and variations of sliding scale plans. My first essay studies the impact of these restructuring and deregulation efforts on consumer rates, using panel data from a custom survey of state commissions and the Department of Energy. I estimate the residential, small commercial and industrial price equations jointly, and use instrumental variables to control for the potentially endogenous demand and status of deregulation. Consumer choice programs lower the prices by 2.2-20.1% compared to the rate of return regulation, benefiting industrial consumers the most and households the least. These effects appear even one to two years prior to the programs' implementation, and become stronger over time. Price caps lower all prices by 0.0-20.0%, with the same ranking. The impacts of sliding scale plans are close to zero, between -2.6% and +4.0% The second paper evaluates health damages caused by air concentrations of SO2 under three alternative environmental policies leading to identical aggregate emissions: emission caps, a nationwide emission tax, and a system of tradable emission allowances such as the one currently used in the US. The numerical model of the industry finds generators' output, participation in energy trade and SO2 abatement effort under each policy. The resulting SO2 concentrations are used to derive the aggregate health damages using estimates in the medical literature. SO2 concentrations vary across policies even when the aggregate emissions are the same. These variations translate into substantially different losses for any individual state, and, nationwide, to hundreds of millions of dollars of difference in aggregate damages. Emission caps are found to lead to the lowest damages, outperforming the currently used system of allowances by 452 million. A uniform emission tax leads to very similar damages as the system of

  10. Telling Lives in Science: Essays on Scientific Biography

    International Nuclear Information System (INIS)

    Harman, Peter

    1997-01-01

    This collection of ten essays by historians of science, several of them biographers, is concerned with the role of scientific biography in forming conceptions of science and scientists. The essays include studies of the biographies of individual scientists, assessments of the aims and style of scientific portraits in different historical contexts, examinations of changing biographical interpretations of scientists, and much discussion of the methodological issues involved in the writing of scientific biographies. Many historians consider biography to be an ambiguous genre, its appeal based on nostalgia rather than history, with a focus on personality rather than historical context, but the biographer can reply that scientific biography reveals the practice of science at its most fundamental level. Indeed, scientific biography has provided a powerful medium in which public conceptions of science have been established. Einstein observed that 'the essential being of a man of my type lies in what he thinks and how he thinks', and his Autobiographical Notes suppress personality in favour of physics. But the biographer may see matters differently, and wish to integrate the public and the private life of the scientist. In their substantial introduction the editors discuss these and other problems, and the book is directed to the professional concerns of historians of science. While there is little here on the history of physics, Geoffrey Cantor's essay on public images of Faraday as constructed in popular biographies, a discussion of conflicting portraits of Faraday as romantic genius or hard-working slogger, may interest readers of this journal.

  11. Essays on electricity transmission investment and financial transmission rights

    Science.gov (United States)

    Shang, Wenzhuo

    The U.S. electric power industry has been going through fundamental restructuring and realignment since the 1990's. Many issues and problems have emerged during the transition, and both economists and engineers have been looking for the solutions fervently. In this dissertation, which consists primarily of three essays, we apply economics theory and techniques to the power industry and address two related issues, transmission investment and financial transmission rights (FTRs). The first essay takes the decentralized perspective and investigates the efficiency attribute of market-based transmission investment under perfect competition. We clarify, for the first time, the nature of the externality created by loop flows that causes transmission investment to be inefficient. Our findings have important implications for better understanding of transmission market design and creating incentives for efficient transmission investment. In the second essay, we define several rules for allocating transmission investment cost within the framework of cooperative game theory. These rules provide fair, stable or efficient cost allocations in theory and are good benchmarks against which the allocation mechanism in practice can be compared and improved upon. In the last essay, we make exploratory efforts in analyzing and assessing empirically the performance of the Midwest independent system operator (MISO) FTR auction market. We reveal some stylized facts about this young market and find that it is not efficient under the risk-neutrality assumption. We also point out and correct the drawbacks in previous related work and suggest about more complete empirical work in future. In all, this dissertation makes both theoretic and empirical analysis of the two hot issues related to the power industry and comes up with findings that have important implications for the development of this industry.

    The injuries sustained in 295 karate contests were analysed. It was noted that in 25 per cent of the contests there was some sort of injury, and in 10 per cent the injury was severe enough to cause the withdrawal of the participant. Injury seemed to occur most commonly among lower-grade participants and more often in the first hour of each day's competition. Protective padding of the arms, legs, feet and hands, and the use of gumshields and protective boxes appeared to reduce the incidence and severity of injury.

The estimated coefficient of HHI is non-positive and statistically insignificant, indicating that higher concentration level does not lead to high price and the container liner shipping market is contestable for the period under consideration. The suggestion that efficiency can be achieved without actual competition in a contestable market is highly significant for policy makers.

  16. Two Essays in Financial Economics

    Science.gov (United States)

    Putnam, Kyle J.

    The following dissertation contains two distinct empirical essays which contribute to the overall field of Financial Economics. Chapter 1, entitled "The Determinants of Dynamic Dependence: An Analysis of Commodity Futures and Equity Markets," examines the determinants of the dynamic equity-commodity return correlations between five commodity futures sub-sectors (energy, foods and fibers, grains and oilseeds, livestock, and precious metals) and a value-weighted equity market index (S&P 500). The study utilizes the traditional DCC model, as well as three time-varying copulas: (i) the normal copula, (ii) the student's t copula, and (iii) the rotated-gumbel copula as dependence measures. Subsequently, the determinants of these various dependence measures are explored by analyzing several macroeconomic, financial, and speculation variables over different sample periods. Results indicate that the dynamic equity-commodity correlations for the energy, grains and oilseeds, precious metals, and to a lesser extent the foods and fibers, sub-sectors have become increasingly explainable by broad macroeconomic and financial market indicators, particularly after May 2003. Furthermore, these variables exhibit heterogeneous effects in terms of both magnitude and sign on each sub-sectors' equity-commodity correlation structure. Interestingly, the effects of increased financial market speculation are found to be extremely varied among the five sub-sectors. These results have important implications for portfolio selection, price formation, and risk management. Chapter 2, entitled, "US Community Bank Failure: An Empirical Investigation," examines the declining, but still pivotal role, of the US community banking industry. The study utilizes survival analysis to determine which accounting and macroeconomic variables help to predict community bank failure. Federal Deposit Insurance Corporation and Federal Reserve Bank data are utilized to compare 452 community banks which failed between

  18. Essays on incomplete contracts in regulatory activities

    Science.gov (United States)

    Saavedra, Eduardo Humberto

    This dissertation consists of three essays. The first essay, The Hold-Up Problem in Public Infrastructure Franchising, characterizes the equilibria of the investment decisions in public infrastructure franchising under incomplete contracting and ex-post renegotiation. The parties (government and a firm) are unable to credibly commit to the contracted investment plan, so that a second step investment is renegotiated by the parties at the revision stage. As expected, the possibility of renegotiation affects initial non-verifiable investments. The main conclusion of this essay is that not only underinvestment but also overinvestment in infrastructure may arise in equilibrium, compared to the complete contracting case. The second essay, Alternative Institutional Arrangements in Network Utilities: An Incomplete Contracting Approach, presents a theoretical assessment of the efficiency implications of privatizing natural monopolies which are vertically related to potential competitive firms. Based on the incomplete contracts and asymmetric information paradigm. I develop a model that analyzes the relative advantages of different institutional arrangements---alternative ownership and market structures in the industry--- in terms of their allocative and productive efficiencies. The main policy conclusion of this essay is that both ownership and the existence of conglomerates in network industries matter. Among other conclusions, this essay provides an economic rationale for a mixed economy in which the network is public and vertical separation of the industry when the natural monopoly is under private ownership. The last essay, Opportunistic Behavior and Legal Disputes in the Chilean Electricity Sector, analyzes post-contractual disputes in this newly privatized industry. It discusses the presumption that opportunistic behavior and disputes arise due to inadequate market design, ambiguous regulation, and institutional weaknesses. This chapter also assesses the presumption

    This essay considers the stories behind the production and screening of two very different Peruvian films that both reveal much about the way the archive, the archival object and archival fragment have worked to disrupt and force a reconsideration of key moments in Peruvian political history of the twentieth century.

    Third-year medical students are graded according to subjective performance evaluations and standardized tests written by the National Board of Medical Examiners (NBME). Many "poor" standardized test takers believe the heavily weighted NBME does not evaluate their true fund of knowledge and would prefer a more open-ended forum to display their individualized learning experiences. Our study examined the use of an essay examination as part of the surgical clerkship evaluation. We retrospectively examined the final surgical clerkship grades of 781 consecutive medical students enrolled in a large urban academic medical center from 2005 to 2011. We examined final grades with and without the inclusion of the essay examination for all students using a paired t test and then sought any relationship between the essay and NBME using Pearson correlations. Final average with and without the essay examination was 72.2% vs 71.3% (P essay examination increasing average scores by .4, 1.8, and 2.5 for those receiving high pass, pass, and fail, respectively. The essay decreased the average score for those earning an honors by .4. Essay scores were found to overall positively correlate with the NBME (r = .32, P essay examination as part of the third-year surgical core clerkship final did increase the final grade a modest degree, especially for those with lower scores who may identify themselves as "poor" standardized test takers. A more open-ended forum may allow these students an opportunity to overcome this deficiency and reveal their true fund of surgical knowledge. Copyright © 2016 Elsevier Inc. All rights reserved.

  2. Three essays in energy and environmental economics

    Science.gov (United States)

    Redlinger, Michael

    This thesis exploits the boom in U.S. oil and gas production to explore several empirical questions in environmental and energy economics. In the first essay, statistical techniques are employed to evaluate learning-by-doing in the Bakken Shale Play. Furthermore, the essay demonstrates organizational forgetting and knowledge spillovers among firms. The results show rates of learning in an important sector the U.S. economy and may have broader lessons for productivity gains and losses. The second essay investigates interfirm learning economies in oil well drilling in terms of productivity improvements and increases in environmental safety. The empirical results improve our understanding of how interfirm relationships influence productivity as well as the drivers of environmental incidents. Lastly, the third essay analyzes the impacts of stricter environmental regulations on oil production and well drilling in North Dakota. The results have particular relevance for policymakers seeking to understand the trade-offs between resource development and environmental quality. These three essays ultimately expand our knowledge of how learning economies occur and the effects of environmental regulations on economic activity.

  4. Essays on Macroeconomics and Oil

    Science.gov (United States)

    Cakir, Nida

    In these essays, I examine (i) the empirical methods that are widely used in the literature to measure total factor productivity growth and (ii) the impact of nationalization on productivity in the oil industry. The first chapter, which is an ongoing work with SHI, Wei, investigates two empirical measures, quantity-based (primal) measure and price-based (dual) measure, of total factor productivity growth. My co-author and I analyze how these two measures are affected by output market imperfection or variable capacity utilization. We find that under constant-returns-to-scale production function assumption, existence of the imperfect competition in the output market creates a gap between the measured TFP growth and the true TFP growth, no matter which method is used. However, theoretically, it does not affect the equivalence between the two measures. Under variable capacity utilization, we show that constant-returns-to-scale assumption is almost enough to guarantee the validity of the two methods in correctly capturing the true TFP growth. In the second and third chapters, I analyze the link between nationalization and productivity. The second chapter documents the trends in expropriation acts, and evaluates the impact of expropriations on labor productivity of resource-rich developing countries in the oil industry. In the first part of this chapter, I investigate the trends in the expropriation acts that took place in 102 developing countries during the period 1922-2006. I find that more than half of the acts occurred between 1970 and 1976, there has been an increase in the number of expropriations in recent years, and the extractive sector including petroleum is more likely to be expropriated. Motivated by these facts, in the second part, I examine the oil industry in a period of widespread expropriations, the 1970s. In a sample of major oil-producing countries including OPEC and non-OPEC members, I show that losses in relative labor productivity after

    Full Text Available Seventy-percent of Americans search health information online, half of whom access medical content on social media websites.  In spite of this broad usage, the medical community underutilizes social media to distribute preventive health information.  This project aimed to highlight the promise of social media for delivering skin cancer prevention messaging by hosting and quantifying the impact of an online video contest. In 2010 and 2011, we solicited video submissions and searched existing YouTube videos.  Three finalists were selected and ranked. Winners were announced at national dermatology meetings and publicized via a contest website. Afterwards, YouTube view counts were monitored.  No increase in video viewing frequency was observed following the 2010 or 2011 contest.  This contest successfully identified exemplary online sun safety videos; however, increased viewership remains to be seen.  Social media offers a promising outlet for preventive health messaging. Future efforts must explore strategies for enhancing viewership of online content.

    5 years ago, the Family Planning Association of Liberia (FPAL) was perturbed by the very minimal youth participation in its programs. Male participation was also at its lowest. The president of the Association then hit upon an innovative idea: a Gentleman of the Year contest. The contestants are selected on the basis of the following criteria: they must be between the ages of 21 and 30 years, at least high school graduates, sportsmen, and possessed of good character and good health. They should also have some knowledge of family planning. The contestants appear before the judges 5 times. For their 1st appearance they don sportswear; for their 2nd, African attire; and for the 5th, a business suit. During their 3rd and 4th appearances they display a talent and go through an interview. As a result of the contest, the FPAL can now boast a viable National Youth Department. The FPAL considers the National Youth Department its most valuable program. A budgetary allocation for it has been included in the Association's 3 year plan to enable the Department to function even more effectively. Plans are also being made for a youth seminar.

    A discriminant analysis was conducted to investigate how an essay, a mathematics/science type of essay, a college scholastic ability test, and grade point average affect acceptance to a pre-med course at a Korean medical school. Subjects included 122 and 385 applicants for, respectively, early and regular admission to a medical school in Korea. The early admission examination was conducted in October 2007, and the regular admission examination was conducted in January 2008. The analysis of early admission data revealed significant F values for the mathematics/science type of essay (51.64; Pgrade point average (10.66; P=0.0014). The analysis of regular admission data revealed the following F values: 28.81 (Pgrade point average, 27.47 (P<0.0001) for college scholastic ability test, 10.67 (P=0.0012) for the essay, and 216.74 (P<0.0001) for the mathematics/science type of essay. Since the mathematics/science type of essay had a strong effect on acceptance, an emphasis on this requirement and exclusion of other kinds of essays would be effective in subsequent entrance examinations for this premed course.

  7. Innovation contests to promote sexual health in china: a qualitative evaluation

    2017-01-01

    Full Text Available Abstract Background Innovation contests call on non-experts to help solve problems. While these contests have been used extensively in the private sector to increase engagement between organizations and clients, there is little data on the role of innovation contests to promote health campaigns. We implemented an innovation contest in China to increase sexual health awareness among youth and evaluated community engagement in the contest. Methods The sexual health image contest consisted of an open call for sexual health images, contest promotion activities, judging of entries, and celebrating contributions. Contest promotion activities included in-person and social media feedback, classroom didactics, and community-driven activities. We conducted 19 semi-structured interviews with a purposive sample to ensure a range of participant scores, experts and non-expert participants, submitters and non-submitters. Transcripts of each interview were coded with Atlas.ti and evaluated by three reviewers. Results We identified stages of community engagement in the contest which contributed to public health impact. Community engagement progressed across a continuum from passive, moderate, active, and finally strong engagement. Engagement was a dynamic process that appeared to have little relationship with formally submitting an image to the contest. Among non-expert participants, contest engagement increased knowledge, healthy attitudes, and empowered participants to share ideas about safe sex with others outside of the contest. Among experts who helped organize the contest, the process of implementing the contest fostered multi-sectoral collaboration and re-oriented public health leadership towards more patient-centered public health campaigns. Conclusion The results of this study suggest that innovation contests may be a useful tool for public health promotion by enhancing community engagement and re-orienting health campaigns to make them more patient-centered.

    Science.gov (United States)

    Skinner, Mark W; Winterton, Rachel

    2018-01-18

    Informed by a critical turn underway in rural gerontology, this article explores how the intersection of global and local trends relating to population aging and rural change create contested spaces of rural aging. The aim is to build our understanding of rural as a dynamic context within which the processes, outcomes, and experiences of aging are created, confronted, and contested by older adults and their communities. A review of key developments within gerontology and rural studies reveals how competing policies, discourses, and practices relating to healthy aging and aging in place, rural citizenship and governmentality, and social inclusion and inequality combine in particular ways to empower or disempower a diverse range of older rural adults aging in a diverse range of rural communities. The article provides a contextually sensitive perspective on potential sources of conflict and exclusion for older adults in dynamic rural spaces and further enhances our understanding of how rural physical and social environments are constructed and experienced in older age. A framework for interrogating emergent questions about aging in rural contexts is developed and implications for advancing research, policy, and practice are discussed. © The Author(s) 2017.

  16. The everyday lives of energy transitions: Contested sociotechnical imaginaries in the American West.

    Science.gov (United States)

    Smith, Jessica M; Tidwell, Abraham Sd

    2016-06-01

    This article brings together two growing literatures - on sociotechnical imaginaries in science and technology studies and on resource materialities in anthropology - to explore how two energy-producing communities in the American West understand the moral salience of energy systems and the place of labor within them. Studies of energy sociotechnical imaginaries overwhelmingly focus on the role that state and transnational actors play in shaping perceptions of the 'good society', rather than how these imaginaries inform and are transformed in the lived experience of everyday people. We illuminate the contested dimension of sociotechnical imaginaries and their positioning within structures of power that inform visions of moral behavior and social order. Whereas the role of energy in national imaginaries is grounded almost entirely in the consumption it enables, examining the everyday ethics of people who live and work in Colorado's uranium-rich Western Slope and Wyoming's coal-rich Powder River Basin reveals an insistence that 'good' energy systems also provide opportunities for dignified and well-paid blue-collar work. This imaginary, we argue, remains 'bounded' at a local scale rather than circulating more widely to gain national or international traction. Theorizing this boundedness illustrates not only the contested nature of sociotechnical imaginaries, but also the constraints that material assemblages and sediments of the past place on imagined futures.

  18. Telling Lives in Science: Essays on Scientific Biography

    Energy Technology Data Exchange (ETDEWEB)

    Harman, Peter

    1997-09-01

    This collection of ten essays by historians of science, several of them biographers, is concerned with the role of scientific biography in forming conceptions of science and scientists. The essays include studies of the biographies of individual scientists, assessments of the aims and style of scientific portraits in different historical contexts, examinations of changing biographical interpretations of scientists, and much discussion of the methodological issues involved in the writing of scientific biographies. Many historians consider biography to be an ambiguous genre, its appeal based on nostalgia rather than history, with a focus on personality rather than historical context, but the biographer can reply that scientific biography reveals the practice of science at its most fundamental level. Indeed, scientific biography has provided a powerful medium in which public conceptions of science have been established. Einstein observed that 'the essential being of a man of my type lies in what he thinks and how he thinks', and his Autobiographical Notes suppress personality in favour of physics. But the biographer may see matters differently, and wish to integrate the public and the private life of the scientist. In their substantial introduction the editors discuss these and other problems, and the book is directed to the professional concerns of historians of science. While there is little here on the history of physics, Geoffrey Cantor's essay on public images of Faraday as constructed in popular biographies, a discussion of conflicting portraits of Faraday as romantic genius or hard-working slogger, may interest readers of this journal.

    2013-01-01

    It might appear odd or even perverse to be arguing for the essay as a vehicle for academic thought and writing, particularly given the current emphasis on scientific research and evidence-based practice. In fact, the scholarly essay has virtually ceased to exist as an academic form in practice disciplines such as nursing, excluded by what we will identify and refer to as the hegemony of the laboratory. In a practical as well as an intellectual attempt to reinstate it, this paper is structured in the form of two consecutive short essays. In the first, we identify the character, features and purpose of the scholarly essay and examine its demise as an academic form. In the second, we explore some possible reasons why the essay never became fully accepted as an academic form in nursing. We suggest that the essay is thematically eclectic and stylistically promiscuous, drawing from a broad range of cultural, disciplinary and academic reference points. As such, it presents a challenge to the dominant technical rational approach to academic nursing in both its form and its content, particularly in its disregard for the rigidly imposed genres and structures increasingly demanded by academic nursing journals.

  1. Hmong transnational identity: the gendering of contested discourses

    Directory of Open Access Journals (Sweden)

    Roberta Julian

    2005-01-01

    Full Text Available Hmong women throughout the diaspora are increasingly expressing ‘what it means to be Hmong’ and ‘what it means to be a Hmong woman’ in a variety of media that constitute western popular culture. At the same time, Hmong women residing in different nation-states live Hmong femininity differently. This paper explores the contested nature of Hmong identity through an exploration of discourses and practices at global and local levels, with a particular emphasis on their gendered dimensions. The paper argues that global narratives of Hmong identity are analytically distinct from, but empirically intertwined with, the constructions of Hmong identities across transnational social spaces. Through a focus on Hmong in Australia and the United States, the paper highlights the significance of place, generation, gender, religion, class and status as axes of contestation and debate in the construction of Hmong identities.

    Innovation contests are a novel approach to elicit good ideas and innovative practices in various areas of public health. There remains limited published literature on approaches to deliver hepatitis testing. The purpose of this innovation contest was to identify examples of different hepatitis B and C approaches to support countries in their scale-up of hepatitis testing and to supplement development of formal recommendations on service delivery in the 2017 World Health Organization hepatitis B and C testing guidelines. This contest involved four steps: 1) establishment of a multisectoral steering committee to coordinate a call for contest entries; 2) dissemination of the call for entries through diverse media (Facebook, Twitter, YouTube, email listservs, academic journals); 3) independent ranking of submissions by a panel of judges according to pre-specified criteria (clarity of testing model, innovation, effectiveness, next steps) using a 1-10 scale; 4) recognition of highly ranked entries through presentation at international conferences, commendation certificate, and inclusion as a case study in the WHO 2017 testing guidelines. The innovation contest received 64 entries from 27 countries and took a total of 4 months to complete. Sixteen entries were directly included in the WHO testing guidelines. The entries covered testing in different populations, including primary care patients (n = 5), people who inject drugs (PWID) (n = 4), pregnant women (n = 4), general populations (n = 4), high-risk groups (n = 3), relatives of people living with hepatitis B and C (n = 2), migrants (n = 2), incarcerated individuals (n = 2), workers (n = 2), and emergency department patients (n = 2). A variety of different testing delivery approaches were employed, including integrated HIV-hepatitis testing (n = 12); integrated testing with harm reduction and addiction services (n = 9); use of electronic medical records to support targeted testing (n = 8

    CERN Document Server

    2017-01-01

    This Festschrift contains numerous colorful and eclectic essays from well-known mathematicians, philosophers, logicians, and linguists celebrating the 90th birthday of Reuben Hersh. The essays offer, in part, attempts to answer the following questions set forth by Reuben himself as a focus for this volume: Can practicing mathematicians, as such, contribute anything to the philosophy of math? Can or should philosophers of math, as such, say anything to practicing mathematicians? Twenty or fifty years from now, what will be similar, and what will, or could, or should be altogether different: About the philosophy of math? About math education? About math research institutions? About data processing and scientific computing? The essays also offer glimpses into Reuben’s fertile mind and his lasting influence on the mathematical community, as well as revealing the diverse roots, obstacles and philosophical dispositions that characterize the working lives of mathematicians.

    A video contest was launched this year to mark the 10th anniversary of the Frederick Phineas and Sandra Priest Rose Centre for Earth and Space. Luke Cahill, a 27 year-old BFA graduate, has just won the contest with a movie about CERN.   Luke, who works in the film industry in Los Angeles and also takes physics classes, came across a video promoting the contest while he was browsing the American Natural History Museum website. "It seemed like a perfect opportunity to combine my passion for science with my craft of filmmaking", says Luke. Luke decided to make a video about the LHC. To him, CERN embodies the ideals of scientific progress and discovery, continually expanding the boundaries of our knowledge. "I have never actually been to CERN but it's high on the list of places I want to visit when I travel to Europe", says Luke. There is a lot of misleading information on the Internet about CERN – especially about the LHC. Luke wanted to clarify what the ...

  11. Experience affects the outcome of agonistic contests without affecting the selective advantage of size.

    2009-06-01

    In the field, phenotypic determinants of competitive success are not always absolute. For example, contest experience may alter future competitive performance. As future contests are not determined solely on phenotypic attributes, prior experience could also potentially alter phenotype-fitness associations. In this study, we examined the influence of single and multiple experiences on contest outcomes in the jumping spider Phidippus clarus. We also examined whether phenotype-fitness associations altered as individuals gained more experience. Using both size-matched contests and a tournament design, we found that both winning and losing experience affected future contest success; males with prior winning experience were more likely to win subsequent contests. Although experience was a significant determinant of success in future contests, male weight was approximately 1.3 times more important than experience in predicting contest outcomes. Despite the importance of experience in determining contest outcomes, patterns of selection did not change between rounds. Overall, our results show that experience can be an important determinant in contest outcomes, even in short-lived invertebrates, and that experience alone is unlikely to alter phenotype-fitness associations.

  12. Improving Undergraduates’ Argumentative Group Essay Writing through Self-assessment

    Directory of Open Access Journals (Sweden)

    Yong Mei Fung

    2015-10-01

    Full Text Available When writing an argumentative essay, writers develop and evaluate arguments to embody, initiate, or simulate various kinds of interpersonal and textual interaction for reader consideration (Wu & Allison, 2003. This is quite challenging for English as a second language (ESL learners. To improve the quality of their writing, students need to review their draft throughout the writing process. This study aimed to investigate the effect of self-assessment in group writing and how group work improves students’ writing ability. An intact class comprising 22 first-year undergraduates participated in the study.  Data were collected from pre- and post-treatment writing tests, semi-structured interview and reflection entries. The results revealed that self-assessment has a significant effect on students’ writing performance. Group work also enhanced social and cognitive development of the students. This study provides insights into the use of self-assessment in writing class to develop learner autonomy and improve writing ability.

    The first essay focuses on Credit default swap (CDS) premiums of safe sovereigns, that is, the insurance against the default of countries with a low credit risk, like Germany, Japan, or the United States. We motivate the essay by establishing the following two stylized facts. First, we document...... insurance against the default of safe sovereigns? Second, what drives safe-haven CDS premiums if not credit risk?...... between bond yield and risk-free rate, for safe sovereigns. This finding is in opposition to the no-arbitrage theory that CDS premiums and yield spreads should move in lockstep. Motivated by these stylized facts, we investigate the following two questions: First, what are the motives behind purchasing...

  14. Essays in renewable energy and emissions trading

    Science.gov (United States)

    Kneifel, Joshua D.

    Environmental issues have become a key political issue over the past forty years and has resulted in the enactment of many different environmental policies. The three essays in this dissertation add to the literature of renewable energy policies and sulfur dioxide emissions trading. The first essay ascertains which state policies are accelerating deployment of non-hydropower renewable electricity generation capacity into a states electric power industry. As would be expected, policies that lead to significant increases in actual renewable capacity in that state either set a Renewables Portfolio Standard with a certain level of required renewable capacity or use Clean Energy Funds to directly fund utility-scale renewable capacity construction. A surprising result is that Required Green Power Options, a policy that merely requires all utilities in a state to offer the option for consumers to purchase renewable energy at a premium rate, has a sizable impact on non-hydro renewable capacity in that state. The second essay studies the theoretical impacts fuel contract constraints have on an electricity generating unit's compliance costs of meeting the emissions compliance restrictions set by Phase I of the Title IV SO2 Emissions Trading Program. Fuel contract constraints restrict a utility's degrees of freedom in coal purchasing options, which can lead to the use of a more expensive compliance option and higher compliance costs. The third essay analytically and empirically shows how fuel contract constraints impact the emissions allowance market and total electric power industry compliance costs. This paper uses generating unit-level simulations to replicate results from previous studies and show that fuel contracts appear to explain a large portion (65%) of the previously unexplained compliance cost simulations. Also, my study considers a more appropriate plant-level decisions for compliance choices by analytically analyzing the plant level decision-making process to

His contribution to aesthetic theory is developed in the Critique of Judgement (1790), where he investigates the possibility and logical status of “judgements of taste”. In this essay, I argue that his exploration of the inherent limits of our knowledge through philosophical reasoning seems to impede an understanding of the musical expe...

  19. Essays on environmental policies, corruption, and energy

    Science.gov (United States)

    Baksi, Soham

    This thesis consists of four essays. The first essay looks at pollution taxation under capital mobility, and analyzes the role of pre-commitment by countries to their pollution tax rate. A polluting firm sells its product in two countries, and can locate and produce in a single country or in both countries. Due to the discrete-choice nature of the firm's location problem, the countries' welfare functions are discontinuous in their pollution tax rate. We show that when the countries cannot pre-commit to their pollution tax, the firm can still engender tax competition between them by strategically locating in both the countries. Moreover, pre-commitment pollution taxation may not be welfare improving for the countries, although it always makes the firm better off. The second essay studies the effect of liberalization on corruption. Corruptible inspectors enforce an environmental regulation on firms, and are monitored by an honest regulator. Liberalization not only increases the variety of goods and the marginal utility of accepting a bribe, but also puts pressure on the regulator to curb corruption. The interaction of these two effects can cause corruption to initially increase with liberalization, and then decrease beyond a threshold. Moreover, equilibrium corruption is lower when the regulator is able to pre-commit to her monitoring frequency. The third essay analyzes optimal labeling (information revelation) procedures for hidden attributes of credence goods. Consumers are heterogeneous in their preference for the hidden attribute, and producers can either self-label their products, or have them certified by a third party. The government can impose self or third-party labeling requirements on either the "green" or the "brown" producers. When corrupt producers can affix spurious labels, the government needs to monitor them. A mandatory self-labeling policy is shown to generally dominate mandatory third-party labeling. The fourth essay develops formulas for

    The present analysis suggests that Turkey’s basin and regional hegemony is contested and constrained from different sides, not least at home. Its water projects are a flashpoint of domestic, basin as well as global politics. It argues that the need to access capital in the international market to realise these ambitions necessitated a 'passive revolution' in Turkey which opened a window of opportunity utilised by the internationalised counter-hegemonic moves against Turkey’s dam projects in Southeast Anatolia, notably the ongoing Ilisu dam on the Tigris.

  5. Essays on oil and the macroeconomy

    Energy Technology Data Exchange (ETDEWEB)

    Melolinna, M.

    2012-07-01

    This dissertation studies the effects of crude oil on the macroeconomy using a vector autoregression (VAR) modelling framework. In particular, the importance of identifying different types of oil shocks is explored for both small and large open economies. A VAR model is also used to study the information content of oil futures contracts. The dissertation consists of three essays. The first essay of the dissertation introduces a methodology for identifying oil supply shocks in a small open economy. Financial market information is used to construct an identification scheme that forces the response to an oil shock of the VAR model to be the same as that implied by futures markets. Due to the identification scheme, the model is only partially identified, and confidence intervals for impulse responses are calculated by using a bootstrapping procedure. The methodology is applied in illustrative examples to two small open economies in a VAR model that includes key domestic and international macroeconomic variables. The results suggest that while oil supply shocks have had an effect on domestic inflation during recent past, the effect on domestic GDP is ambiguous. The second essay of the dissertation studies the existence of risk premiums in crude oil futures prices with simple ordinary least squares regression and Bayesian VAR models. It also studies the importance of three main theoretical risk premium models in explaining and forecasting the risk premiums in practice. Whilst the existence of the premiums and the validity of the models can be established at certain time points, it turns out that the choice of sample period has a considerable effect on the results. Hence, the risk premiums are highly time-varying. The study also establishes a model, based on speculative positions in the futures markets, which has some predictive power for future oil spot prices. The third essay of the dissertation explores oil market and other macroeconomic shocks in a structural VAR

    Full Text Available The continuity of Indonesian transborder fishing activities into Australian Fishing Zone (AFZ highlights the rooted dispute of maritime border when contested space of boundary shared by local, state and international actor is confronted. Therefore, the prevailing of multilayer perspective of maritime boundary should not be easily neglected. The colonial project in early 19th century in Southeast Asia that initiated the foundation of modern state-formation had challenged the prior-political and economic construction of the region, specifically on the issue of territoriality. The modernization of shipping and fishing activities of which relied on technology and capitals had generated political and economic competitions and later persuaded state’s actors of applying the strategy of the territorialisation of the sea in order to ensure control. Unavoidably, securitization of transborder fishing became preferable solution. Transborder fishings are further subjected into state control relied on territorial sovereignty. This paper examines the transformation of transborder fishing in Timor and Arafura Sea to demonstrated the contested space of which interplayed by local, state and international actor. State regulations had transformed transborder fishing into political space of authority competition relied on territorial sovereignty, while socio-cultural heritage reminds exploited within fluid space of livelihood survival when state function is just absent.

We found a significant win bias for the first called athlete, but this effect was not significantly related to the color of the judogi. The lack of a significant win effect of judogi color suggests that blue does not bias winning in judo, and that the blue-white pairing ensures an equal level of play.

    Ramalingam, V. V.; Pandian, A.; Chetry, Prateek; Nigam, Himanshu

    2018-04-01

    Essays are paramount for of assessing the academic excellence along with linking the different ideas with the ability to recall but are notably time consuming when they are assessed manually. Manual grading takes significant amount of evaluator’s time and hence it is an expensive process. Automated grading if proven effective will not only reduce the time for assessment but comparing it with human scores will also make the score realistic. The project aims to develop an automated essay assessment system by use of machine learning techniques by classifying a corpus of textual entities into small number of discrete categories, corresponding to possible grades. Linear regression technique will be utilized for training the model along with making the use of various other classifications and clustering techniques. We intend to train classifiers on the training set, make it go through the downloaded dataset, and then measure performance our dataset by comparing the obtained values with the dataset values. We have implemented our model using java.

The researcher compared two sets of scores, the score of students’ lexical richness, measured with LFP (Lexical Frequency Profile, and the score of overall quality of EFL students’ argumentative essay, using analytical scoring rubric. The small and not significant correlation (ñ=.18, sig=.23 implied that diction had small contribution to the overall quality of the essay. There might be another factor related to the diction that supports the quality of written text. Thus, further research is needed to be conducted.

  6. A Corpus-based Study on the Use of Contractions by EFL Learners in Argumentative Essays

    2017-01-01

    Full Text Available Contraction forms in English are mostly occur in speech and informal writing and they are generally avoided in formal writing types such as academic prose, business reports and journal articles, therefore, most teachers discourage their use in academic essays (Biber, Johansonn, Leech, Conrad and Finegan 1999. Contractions in English have two types; negative contractions (isn’t, haven’t, doesn’t and verb contractions (I’m, they’ve, that’s. This corpus based study attempts to investigate contraction usage in learner and native English speaker essays. Major goal is to examine whether learners consider essay writing rules in respect of contractions which are accepted inappropriate for academic prose style. Five corpora, three learner and two native English, were utilized in order to analyze verb and not-contraction forms. Frequency calculations of contraction forms in each corpus compared via log-likelihood measurement for statistical significance.  Results revealed that learners use considerably more contraction forms, especially negative ones, than native English students in their argumentative essays.

  7. A Flipped Writing Classroom: Effects on EFL Learners’ Argumentative Essays

    2018-02-01

    Full Text Available According to the literature, flipped teaching is a relatively new pedagogical approach in which the typical activities of classroom lectures followed by homework in common teaching practice are reversed in order, and most often integrated or supplemented with some types of instructional materials, such as instructional videos or PowerPoint files. This experimental study, using a pre-test-treatment-posttest-delayed posttest design, was aimed at investigating the effect of flipped instruction on Iranian EFL learners’ quality of argumentative essays. The participants were 55 students, who were assigned to two groups: the flipped classroom (FC and the traditional classroom (TC. Each group received 3 sessions of treatment. First, whether there was any significant difference between the FC and TC in the overall quality of the essays was investigated. The FC group significantly outperformed the TC one. Then, whether the difference between the groups varied over time was explored, and it was revealed that the FC was still significantly superior over the TC. Next, whether there would be any significant change in the FC in the long run was examined, and no significant change was seen. The promising results found in FC group can be attributed to not only the flipped instruction but also the process of actively engaging the learners in their learning in addition to incorporating different techniques, such as the video screencasting, collaborative writing, as well as in-class teacher-learner interaction and negotiation because it is argued that the crucial point in flipped instruction is how teachers best use in-class-time with students.

  8. HIV cure research community engagement in North Carolina: a mixed-methods evaluation of a crowdsourcing contest.

    2017-10-01

    The purpose of this study was to evaluate the feasibility of using a crowdsourcing contest to promote HIV cure research community engagement. Crowdsourcing contests are open calls for community participation to achieve a task, in this case to engage local communities about HIV cure research. Our contest solicited images and videos of what HIV cure meant to people. Contestants submitted entries to IdeaScale, an encrypted online contest platform. We used a mixed-methods study design to evaluate the contest. Engagement was assessed through attendance at promotional events and social media user analytics. Google Analytics measured contest website user-engagement statistics. Text from contest video entries was transcribed, coded and analysed using MAXQDA. There were 144 attendees at three promotional events and 32 entries from 39 contestants. Most individuals who submitted entries were black ( n =31), had some college education ( n =18) and were aged 18-23 years ( n =23). Social media analytics showed 684 unique page followers, 2233 unique page visits, 585 unique video views and an overall reach of 80,624 unique users. Contest submissions covered themes related to the community's role in shaping the future of HIV cure through education, social justice, creativity and stigma reduction. Crowdsourcing contests are feasible for engaging community members in HIV cure research. Community contributions to crowdsourcing contests provide useful content for culturally relevant and locally responsive research engagement.

  9. Essays on regulation, institutions, and industrial organization

    Science.gov (United States)

    Bergara, Mario Esteban

    Essay I develops a comparative institutional analysis of network access price regulation and "light-handed" regulation. While the former is a specific-agency-based arrangement with higher political influence, the latter is a court-based system. Consequently, the main trade-off between both frameworks reflects the merits of having efficient political and judicial institutions. Price regulation is superior when distributional concerns are irrelevant and information asymmetries are lower. Poorly functioning political systems and high welfare costs of raising funds make price regulation less attractive. Light regulation is more attractive when potential rents are smaller, the monopolist is more risk averse, the judicial system is more efficient, and the threat of government intervention is more credible. The possibility of private transfers makes price regulation more advantageous. Higher information asymmetries among firms makes light-handed regulation more attractive. The main results are consistent with a plausible interpretation of the drastic deregulatory process in New Zealand. Essay II studies the preliminary effects of the deregulation of direct access in the New Zealand's electricity market. A slight improvement in quality standards and an overall efficiency increase took place after two years of deregulation. Retailers were able to successfully enter in large demand, dense areas, with a large proportion of industrial and commercial users, where incumbents were not distributing electricity efficiently. Pricing policies appears to be influenced by market forces (associated to economic and demographic characteristics) as expected in a light regulatory framework. Essay III focuses on the possibility of endogenous sunk costs and the introduction of new products. Firms that exert some monopoly power in one market and introduce a new good whose demand is determined by a broader set of consumers might be forced to change their competing strategies. If the new product

    Martinez-Chombo, Eduardo

    Electricity demand analysis using cointegration and error-correction models with time varying parameters: The Mexican case. In this essay we show how some flexibility can be allowed in modeling the parameters of the electricity demand function by employing the time varying coefficient (TVC) cointegrating model developed by Park and Hahn (1999). With the income elasticity of electricity demand modeled as a TVC, we perform tests to examine the adequacy of the proposed model against the cointegrating regression with fixed coefficients, as well as against the spuriousness of the regression with TVC. The results reject the specification of the model with fixed coefficients and favor the proposed model. We also show how some flexibility is gained in the specification of the error correction model based on the proposed TVC cointegrating model, by including more lags of the error correction term as predetermined variables. Finally, we present the results of some out-of-sample forecast comparison among competing models. Electricity demand and supply in Mexico. In this essay we present a simplified model of the Mexican electricity transmission network. We use the model to approximate the marginal cost of supplying electricity to consumers in different locations and at different times of the year. We examine how costs and system operations will be affected by proposed investments in generation and transmission capacity given a forecast of growth in regional electricity demands. Decomposing electricity prices with jumps. In this essay we propose a model that decomposes electricity prices into two independent stochastic processes: one that represents the "normal" pattern of electricity prices and the other that captures temporary shocks, or "jumps", with non-lasting effects in the market. Each contains specific mean reverting parameters to estimate. In order to identify such components we specify a state-space model with regime switching. Using Kim's (1994) filtering algorithm

    This essay drews attention to two books on empires by historians which deserve the attention of sociologists. Bang's model of the workings of the Roman economy powerfully demonstrates the tributary nature of per-industrial tributary empires. Darwin's analysis concentrates on modern overseas empires, wholly different in character as they involved the transportation of consumption items for the many rather than luxury goods for the few. Darwin is especially good at describing the conditions of existence of late nineteenth century empires, noting that their demise was caused most of all by the failure of balance of power politics in Europe. Concluding thoughts are offered about the USA. © London School of Economics and Political Science 2011.

    The first essay investigates how credit risk, the risk that a bond issuer will default, affects bond market liquidity. Specifically, we depart from the current literature in that we analyze the direct and indirect channels through which credit risk affects market liquidity, rather than determining...... whether both are priced in the bond. We focus on the Italian sovereign bond market, which allows us to determine how central bank interventions affect the sensitivity of the liquidity provision by market makers to default risk. We motivate our empirical analysis with a simple model of a risk averse market...... maker, holding an inventory of a risky asset and setting her optimal marginal quotes (and, therefore, the optimal bid-ask spread), in the presence of margin constraints and borrowing costs. The margins, set by a clearing house, depend on the risk of the asset, as measured by the CDS spread...

    1978-01-01

    This is Part 2 of a transcription of Bentham's manuscript essay on "Paederasty" (1785), Part 1 of which appeared in Vol. 3, No. 4. In Part 1 Bentham argued for the decriminalization of sodomy and opposed the theories of Montesquieu and Voltaire as to its social dangers. In Part 2 Bentham speculates on its causes and alleges that the real reason such behavior is so severely punished is an irrational "antipathy" to pleasure generally and to sexual pleasure in particular. He discusses the danger of blackmail and false accusations and the punishment of lesbian acts, bestiality, and masturbation. Some miscellaneous related notes by Bentham are appended: these deal with religious fears based on the destruction of Sodom, the threat to population, the harshness of English naval law, and other topics.

    2017-01-01

    This book presents a detailed description of the development of statistical theory. In the mid twentieth century, the development of mathematical statistics underwent an enduring change, due to the advent of more refined mathematical tools. New concepts like sufficiency, superefficiency, adaptivity etc. motivated scholars to reflect upon the interpretation of mathematical concepts in terms of their real-world relevance. Questions concerning the optimality of estimators, for instance, had remained unanswered for decades, because a meaningful concept of optimality (based on the regularity of the estimators, the representation of their limit distribution and assertions about their concentration by means of Anderson’s Theorem) was not yet available. The rapidly developing asymptotic theory provided approximate answers to questions for which non-asymptotic theory had found no satisfying solutions. In four engaging essays, this book presents a detailed description of how the use of mathematical methods stimulated...

    Results from four pilot administrations of the Medical College Admission Test essay question are reported. Analyses focused on (a) the performance characteristics of sample groups differentiated by gender, size of hometown, race/ethnicity, and dominant language; (b) the relationships between essay scores and academic/demographic characteristics; and (c) the reliability of one 45-minute versus two 30-minute essays. No differences were found for examinees grouped by gender and size of home community. Mean differences among the racial/ethnic groups were explained largely by reading level differences. Differences in essay performance by language group were large and unexplained by reading level differences. No relationship was found between the essay score and the academic/demographic characteristics. Reliability estimates for two 30-minute essays were higher than for one 45-minute essay; however, the 30-minute period yielded writing of poorer quality. Test-retest reliabilities for the 45-minute topics will remain the focus of future studies as will performance by examinees for whom English is a second language. The impact of the essay on the selection process will also be assessed.

    Directory of Open Access Journals (Sweden)

    Gennadii Vasil’evich Osipov

    2014-11-01

    Full Text Available The essay by Academician G.V. Osipov, who is the patriarch of Russian sociology, is dedicated to one of the most cognitive topics of modern sociology – identification of sociological metaphor as such and its application in research projects. This topic is avant-garde for the world sociological thought, and in Russia such kind of research is making its first steps. However, its future importance is difficult to overestimate. Sociological metaphor, if a methodology for its application is developed, can provide scientists with qualitatively new synthetic research tools. It can also bring together scientific structures and artifacts on the space of interdisciplinary and inter-subject borderland and give them qualitatively new intellectual and sensuous (system and mental technological capabilities for learning the surrounding world. The advantage of the following essay can be found in the fact that it is based on the objective analysis of the real embodiment of social metaphor in the work of art – a pictorial triptych “The Mystery of the 21st Century”. This is the first such experience in domestic sociological and artistic-painting practice. The authors of the final product are a scientist of great scientific and life experience and a young artist, who received in-depth sociological training and defended his Ph.D. in Sociology dissertation. But the main result of their collaboration is a product that combines scientific (sociological knowledge and insight and intuitive-creative artistic perception in a qualitatively new perception of the world and world outlook

  12. Weighing both sides: morality, mortality, and framing contests over obesity.

    Science.gov (United States)

    Saguy, Abigail C; Riley, Kevin W

    2005-10-01

    Despite recent and growing media attention surrounding obesity in the United States, the so-called obesity epidemic remains a highly contested scientific and social fact. This article examines the contemporary obesity debate through systematic examination of the claims and claimants involved in the controversy. We argue that four primary groups-antiobesity researchers, antiobesity activists, fat acceptance researchers, and fat acceptance activists-are at the forefront of this controversy and that these groups are fundamentally engaged in framing contests over the nature and consequences of excess body weight. While members of the fat acceptance groups embrace a body diversity frame, presenting fatness as a natural and largely inevitable form of diversity, members of the antiobesity camp frame higher weights as risky behavior akin to smoking, implying that body weight is under personal control and that people have a moral and medical responsibility to manage their weight. Both groups sometimes frame obesity as an illness, which limits blame by suggesting that weight is biologically or genetically determined but simultaneously stigmatizes fat bodies as diseased. While the antiobesity camp frames obesity as an epidemic to increase public attention, fat acceptance activists argue that concern over obesity is distracting attention from a host of more important health issues for fat Americans. We examine the strategies claimants use to establish their own credibility or discredit their opponents, and explain how the fat acceptance movement has exploited structural opportunities and cultural resources created by AIDS activism and feminism to wield some influence over U.S. public health approaches. We conclude that notions of morality play a central role in the controversy over obesity, as in many medical disputes, and illustrate how medical arguments about body weight can be used to stymie rights claims and justify morality-based fears.

  16. Ethical Concerns of and Risk Mitigation Strategies for Crowdsourcing Contests and Innovation Challenges: Scoping Review

    Science.gov (United States)

    Pan, Stephen W; Mathews, Allison; Stein, Gabriella; Bayus, Barry; Rennie, Stuart

    2018-01-01

    Background Crowdsourcing contests (also called innovation challenges, innovation contests, and inducement prize contests) can be used to solicit multisectoral feedback on health programs and design public health campaigns. They consist of organizing a steering committee, soliciting contributions, engaging the community, judging contributions, recognizing a subset of contributors, and sharing with the community. Objective This scoping review describes crowdsourcing contests by stage, examines ethical problems at each stage, and proposes potential ways of mitigating risk. Methods Our analysis was anchored in the specific example of a crowdsourcing contest that our team organized to solicit videos promoting condom use in China. The purpose of this contest was to create compelling 1-min videos to promote condom use. We used a scoping review to examine the existing ethical literature on crowdsourcing to help identify and frame ethical concerns at each stage. Results Crowdsourcing has a group of individuals solve a problem and then share the solution with the public. Crowdsourcing contests provide an opportunity for community engagement at each stage: organizing, soliciting, promoting, judging, recognizing, and sharing. Crowdsourcing poses several ethical concerns: organizing—potential for excluding community voices; soliciting—potential for overly narrow participation; promoting—potential for divulging confidential information; judging—potential for biased evaluation; recognizing—potential for insufficient recognition of the finalist; and sharing—potential for the solution to not be implemented or widely disseminated. Conclusions Crowdsourcing contests can be effective and engaging public health tools but also introduce potential ethical problems. We present methods for the responsible conduct of crowdsourcing contests. PMID:29523500

    2016-09-01

    Full Text Available This article explores the advent of local newspaper movie contests in the 1910s and how these contests helped to create active movie fans. Such contests increased the popularity of the new medium of film by engaging local audiences in the process of filmmaking, including fans as scriptwriters and even stars. They helped to transform film into a dominant cultural practice by creating local spaces for film patrons to become part of the national pastime of going to the show. They did so by appealing directly to female spectators, who both legitimized going to the movies and created dynamic film fan communities.

  18. Wisdom of the Crowds: Crowd-Based Development of a Logo for a Conference Using a Crowdsourcing Contest.

    Ong, Jason J; Bilardi, Jade E; Tucker, Joseph D

    2017-10-01

    Crowdsourcing methods have been widely used in business, but rarely in sexual health research. We evaluated a crowdsourced logo contest as part of an international human immunodeficiency virus conference. A logo crowdsourcing contest was conducted for the 20th International Acquired Immunodeficiency Syndrome Conference. Crowdsourcing has a group of individuals solve a task, often as part of an open contest. Semistructured interviews were conducted with key informants including contest organizers, contest contributors, and conference attendees. Interviews were transcribed verbatim and analysed using a content analysis approach. In total, 22 interviews were conducted with 3 contest organizers, 7 contest contributors, and 12 conference attendees. All individuals reported that the crowdsourced logo provided benefits beyond branding the conference, including creating a shared sense of purpose among diverse conference participants and explicitly demonstrating the strong community orientation of the conference. Conference organizers and attendees all reported deeper engagement because of the story of the Tanzanian artist who won the contest. Most conference attendees (11/12) preferred the crowdsourced logo compared with the previous company-organized logo, and all (22/22) supported the logo contest continuing. Implementing a logo contest was simple and relatively inexpensive. Stakeholders identified several ways to enhance crowdsourcing logo contest methods including wider promotion of the contest to encourage broader participation, greater transparency in the selection process, and a different prize structure which acknowledges the contribution of more contestants. We found that a crowdsourcing contest helped engage local and global communities in the lead-up before and during an international conference. Similar participatory events may be useful for sexual health conferences and research projects.

  19. Essays on energy derivatives pricing and financial risk management =

    Science.gov (United States)

    Madaleno, Mara Teresa da Silva

    This thesis consists of an introductory chapter (essay I) and five more empirical essays on electricity markets and CO2 spot price behaviour, derivatives pricing analysis and hedging. Essay I presents the structure of the thesis and electricity markets functioning and characteristics, as well as the type of products traded, to be analyzed on the following essays. In the second essay we conduct an empirical study on co-movements in electricity markets resorting to wavelet analysis, discussing long-term dynamics and markets integration. Essay three is about hedging performance and multiscale relationships in the German electricity spot and futures markets, also using wavelet analysis. We concentrate the investigation on the relationship between coherence evolution and hedge ratio analysis, on a time-frequency-scale approach, between spot and futures which conditions the effectiveness of the hedging strategy. Essays four, five and six are interrelated between them and with the other two previous essays given the nature of the commodity analyzed, CO2 emission allowances, traded in electricity markets. Relationships between electricity prices, primary energy fuel prices and carbon dioxide permits are analyzed on essay four. The efficiency of the European market for allowances is examined taking into account markets heterogeneity. Essay five analyzes stylized statistical properties of the recent traded asset CO2 emission allowances, for spot and futures returns, examining also the relation linking convenience yield and risk premium, for the German European Energy Exchange (EEX) between October 2005 and October 2009. The study was conducted through empirical estimations of CO2 allowances risk premium, convenience yield, and their relation. Future prices from an ex-post perspective are examined to show evidence for significant negative risk premium, or else a positive forward premium. Finally, essay six analyzes emission allowances futures hedging effectiveness, providing

    The following essay is a review of the literature about the American eugenics movement produced by scholars over the last fifty years. The essay provides an explanation for today's renewed interest in the subject and for why the science of eugenics remains relevant to contemporary society. The essay examines the catalyst to re-examine the eugenics movement, the influence of Darwinian thought upon its development, the political and institutional support for its growth, the relationship between eugenics, sterilization, and sex, and how the twentieth-century promises of the science of better breeding was a precursor to the twenty-first-century promise of genetic engineering.

    2017-01-01

    How do the levels of extreme positions of various interest groups influence the conservation policies in the context of a renewable resource conservation contest? To answer this question, a model is provided where conservation policy is determined as a contest between two opposing interest groups......: one in favor of conservation and another in favor of non-conservation. The levels of extreme positions for the conservationalists are determined by their demands about the severity of the conservation strategy that needs to be implemented. For the non-conservation group, the level of extreme position...... is determined by how large the current harvest of the resource should be. The main driver of the model is that resource conservation is realized only if the conservation group wins the contest, which again depends on the relative gain the two contenders receive when winning the contest. The paper derives...

    Full Text Available In this paper, I propose to examine how rival global governmentalprojects are asserted and contested by decentralized networks thatlink actors operating at different scales. I argue that Tsing’s notionof «travelling packages» provides a useful way of conceptualizingthe means by which elements of these projects are diffused, translated,taken up, and adapted into different localities around theworld. I explore these dynamics in relation to the contestation of agovernance model based on the principle that the free, prior andinformed consent (FPIC of an indigenous people is required toauthorize actions that may affect upon indigenous territory or indigenousrights.

    With the plethora of information, there are many aspects to contested environments such as the protection of information, network privacy, and restricted observational and entry access. In this paper, we review and contrast the perspectives of challenges and opportunities for future developments in contested environments. The ability to operate in a contested environment would aid societal operations for highly congested areas with limited bandwidth such as transportation, the lack of communication and observations after a natural disaster, or planning for situations in which freedom of movement is restricted. Different perspectives were presented, but common themes included (1) Domain: targets and sensors, (2) network: communications, control, and social networks, and (3) user: human interaction and analytics. The paper serves as a summary and organization of the panel discussion as towards future concerns for research needs in contested environments.

  9. Latin America: Essays Interpretating Colonial Legacy

    Directory of Open Access Journals (Sweden)

    María Pia López

    2013-12-01

    Full Text Available A large part of the Latin–American literature of the 19th and 20th century tried to deal with the national question intertwining different dimensions: the weight of colonial legacy, the cultural peculiarity of the nation and the inner relations between social classes and ethnic groups. Thinking the nation implied, in any case, to think the difference and the conflict with others, as well as the inner conflict and the logic of local colonialism. Analyzing some of these essays that played a central role in such process of recasting the origin of the nation, the author moves around three main axes: the formulation of dualist writings (colonial/national; white /indigenous; civilization/wilderness, the issue of language (the language inherited from the colonial experience versus the multilingual nature of indigenous Latin American societies, and the hypothesis about the birth of the nation – appointed to different groups – and its normal functioning as legitimization of the order sprung from independences.

  10. The Test of Practice–An Essay

    Directory of Open Access Journals (Sweden)

    Lars Løvlie

    2017-02-01

    Full Text Available This essay starts in medias res, in the puzzling reappearance of the classical metaphor of Bildung as the transformation of man’s “first” animal nature into the “second” cultivated one. I call it the two-natures metaphor. I think it misrepresents children by prescribing form rather than asking what actually takes form in the child’s mind—in his/her relationship with adults. It made me wonder whether this mistake also lingers on in the current discourse on education. I then turn to aspects of John Dewey’s subtle and revolutionary critique of the classical theory of formation, but also to make the controversial point that he, too, seems to miss the importance of the child’s internal point of view. The importance of the subjective life of the child is suggested first by reinscribing Rousseau and Kant into the intersubjective theories of Hegel and Dewey; second, by reference to recent studies in developmental psychology that offer detailed and in-depth descriptions of our relationship with children. My basic point of departure is the existential encounters between children and adults, for example, as part of classroom practices. The title has a double connotation. It means that theory must be taken as the measure of practice. It means, too, that practice must work as the measure of theory. I will, in the main, try and pursue the last course.

    Full Text Available The purpose of this paper is to serve as a helpful tool for students, jurists, lawyers, judges and others, in the profesional and scientific aspect. In ruling a contested procedure in a professional manner, the court has to find the truth, so that the contested procedure is most efficient until reaching the final verdict. In my research, I intend to enrich the science with my knowledge in the field of contested procedure. In this study I have used analytical, comparative, synthesis, generalization and other methods. Those reading this paper will understand how evidence is the most important part in a fair trial, since failure to prove claims very often leads towards an incorrect situation; they will understand how difficult and painful would be forfeiting rights for the litigating party, which would lead to serious changes, such as losing property, losing a job, compensation of personal income, compensation for damage caused. The paper in itself contains deposited evidence, which maintain the level of estimation from the court in order to make a judgment in a contested procedure with a court verdict. In this paper I present the subject of: “Means of evidence and evidence collection in contested procedure”, where I have tried to research the theory but also the practice in contested proceedings, addressing the positive aspects, the deficiencies and novelties. In the legal provisions of the Law on Contested Procedure of theRepublicofKosovo, no. 03/L-006, of 30 June 2008, and Law no. 04/L-118, of 13 September 2012, on amendments to the Law on Contested Procedure, evidentiary means and evidence collection are included in chapter XXII.

  18. Interaction location outweighs the competitive advantage of numerical superiority in Cebus capucinus intergroup contests.

    Crofoot, Margaret C; Gilby, Ian C; Wikelski, Martin C; Kays, Roland W

    2008-01-15

    Numerical superiority confers a competitive advantage during contests among animal groups, shaping patterns of resource access, and, by extension, fitness. However, relative group size does not always determine the winner of intergroup contests. Smaller, presumably weaker social groups often defeat their larger neighbors, but how and when they are able to do so remains poorly understood. Models of competition between individuals suggest that location may influence contest outcome. However, because of the logistical difficulties of studying intergroup interactions, previous studies have been unable to determine how contest location and group size interact to shape relationships among groups. We address this question by using an automated radio telemetry system to study intergroup interactions among six capuchin monkey (Cebus capucinus) social groups of varying sizes. We find that the odds of winning increase with relative group size; one additional group member increases the odds of winning an interaction by 10%. However, this effect is not uniform across space; with each 100 m that a group moves away from the center of its home range, its odds of winning an interaction decrease by 31%. We demonstrate that contest outcome depends on an interaction between group size and location, such that small groups can defeat much larger groups near the center of their home range. The tendency of resident groups to win contests may help explain how small groups persist in areas with intense intergroup competition.

  19. Contesting modernity: Tobacco use and romanticism among older Dai farmers in Xishuangbanna, China.

    Zhao, Xiang; Davey, Gareth

    2015-11-01

    The majority of research about tobacco use in China focuses on Han Chinese, the main ethnic group comprising over 90 per cent of the population, and a paucity of research exists on ethnic minorities. The present study elucidates tobacco use among the Dai people, an ethnic group in Yunnan Province, Southwest China. The study design consisted of interviews and grounded theory methodology in a symbolic interactionist theoretical framework. The categories of the grounded theory revealed tobacco consumption was weaved in a complex web of meanings: social practices, perceptions of health, and work lives as agriculturalists, situated in Dai cultural and social milieu. An important finding was the stage-managing of tobacco as a symbol of 'tradition' versus 'modernity': Through a process of contested modernity, the older men championed long-standing tobacco customs as representative of Dai heritage and thus their own tobacco use as upholding traditions amid encroaching cultural and societal change in China. These findings are important because little is known about Dai people's tobacco use and how they are responding to social change. There are also implications for the development of culturally-appropriate tobacco control strategies. © 2015 Foundation for the Sociology of Health & Illness.

    2013-12-01

    The aims of this study were to examine pre-existing videos in order to explore the motivation for, possible approaches to, and timing and context of disclosure of genital herpes infection as described by the lay public. A thematic content analysis was performed on 63 videos submitted to an Australian online contest sponsored by the Australian Herpes Management Forum and Novartis Pharmaceuticals designed to promote disclosure of genital herpes. Videos either provided a motivation for disclosure of genital herpes or directed disclosure without an explicit rationale. Motivations included manageability of the disease or consistency with important values. Evaluation of strategies and logistics of disclosure revealed a variety of communication styles including direct and indirect. Disclosure settings included those that were private, semiprivate and public. Disclosure was portrayed in a variety of relationship types, and at different times within those relationships, with many videos demonstrating disclosure in connection with a romantic setting. Individuals with genital herpes are expected to disclose to susceptible partners. This analysis suggests that understanding lay perspectives on herpes disclosure to a partner may help healthcare providers develop counselling messages that decrease anxiety and foster disclosure to prevent transmission.

  1. "Show me your impact": evaluating transitional justice in contested spaces.

    Science.gov (United States)

    Duggan, Colleen

    2012-02-01

    This paper discusses some of the most significant challenges and opportunities for evaluating the effects of programs in support of transitional justice - the field that addresses how post-conflict or post authoritarian societies deal with legacies of wide spread human rights violations. The discussion is empirically grounded in a case study that assesses the efforts of the International Development Research Centre (IDRC) and one of its Guatemalan partners to evaluate the effects of a museum exposition that is attempting to recast historic memory and challenge racist attitudes in post-conflict Guatemala. The paper argues that despite the increasing trend to fund transitional justice programs, many international aid donors are stuck in traditional and arguably orthodox paradigms of program evaluation. This is having a negative effect not only upon the administration of aid but also upon how transitional justice research is perceived and valued by local populations. The case study experience indicates that there is no perfect evaluation model or approach for evaluating transitional justice programming - only choices to be made by commissioners of evaluation, evaluators, and those being evaluated. These are profoundly influenced by the extreme politics and moral values that define transitional justice settings as contested spaces in which calls to remember the tragic past must be balanced with aspirations to re-build a hopeful future.

Recent studies on mining and gender focus predominantly on women and how they are negatively affected by mining. Ethnicity, although a growing asset in struggles on environmental transformations, is hardly included in research on mining. The intertwinement of ethnicity and gender in elaborations on mining is often depicted in literature of development programs and environmental organizations in which indigenous women are homogenized as marginalized victims. We argue, however, for a multidimensional approach on mining that takes into account the institutionalization of gender and ethnicity in mining governance as well as the role of gender and ethnic identities. Feminist political ecology and institutional analysis are pointing the way for such an approach. Furthermore, other relevant categories such as class, age, or status should be considered in the analysis of the complex and multidimensional environmental transformations of the mining sector in Indonesia.

    The inherent nature of unattended sensors makes these devices most vulnerable to detection, exploitation, and denial in contested environments. Physical access is often cited as the easiest way to compromise any device or network. A new mechanism for mitigating these types of attacks developed under the Assistant Secretary of Defense for Research and Engineering, ASD(R and E) project, "Smoke Screen in Cyberspace", was demonstrated in a live, over-the-air experiment. Smoke Screen encrypts, slices up, and disburses redundant fragments of files throughout the network. Recovery is only possible after recovering all fragments and attacking/denying one or more nodes does not limit the availability of other fragment copies in the network. This experiment proved the feasibility of redundant file fragmentation, and is the foundation for developing sophisticated methods to blacklist compromised nodes, move data fragments from risks of compromise, and forward stored data fragments closer to the anticipated retrieval point. This paper outlines initial results in scalability of node members, fragment size, file size, and performance in a heterogeneous network consisting of the Wireless Network after Next (WNaN) radio and Common Sensor Radio (CSR).

  4. Decision-making and emotions in the contested information environment

    Full Text Available Future conflicts will necessitate the ability to conduct effective military operations in a contested information environment. The building and maintaining of robust situational awareness, protection of decision-making effectiveness of individuals and teams, fighting through information attacks from both in, and through, the cyberspace domain, will be essential. Increasing the knowledge of the mechanisms involved in degrading task performance and decision-making during cyber attacks will enable the development of advanced human-centered defensive techniques that aid fight-through capability. In this position paper, the development and evaluation of software that simulates real-time and persistent manipulation of the information environment is discussed. Results of the evaluation indicated that the task performance of a team of decision-makers performing collaborative tasks could be degraded through real-time manipulation of cyberspace content and operation. The paper concludes with a discussion of focus and direction for future research and development. It is suggested that the building of a deeper understanding of the perceptual and cognitive factors that are significant in the relationship between information environment manipulation and reduction in task performance is required. This understanding will aid in the defence of cyberspace attacks, will aid in fight through and mission assurance, and will aid the Information Operations community.

  5. Contested minorities – the case of Upper Silesia

    Directory of Open Access Journals (Sweden)

    Gierczak Dariusz

    2015-06-01

    Full Text Available Upper Silesia in terms of ethnicity is a typical example of a historical region in Europe, but in fact, one of the few exceptions in contemporary Poland, where its mixed ethnic and religious structures have at least partly survived until today. While their existence had been denied by Nazi Germany (1933-1945 as well as by the Polish People's Republic (1945-1989, the emancipation of the German and Silesian minorities after the democratic changes of 1989 have evoked strong emotions in the ethnically almost uniform country. Nonetheless, the recent situation of minorities has improved as never before. Minority organisations has been officially recognized and German finally has become the second language in some municipalities of Upper Silesia, but the largest ethnic group in the whole country, the Silesians, have still experienced no formal recognition as a national minority. This article deals with the demographic aspects of the ethnic groups in Upper Silesia since the 19th century until recent times. The census results concerning the ethnic minorities or languages in Upper Silesia have been contested since the first records of that kind have been taken. The outcomes of the both last censuses of 2002 and 2011 concerning the minority question reflected for the first time a much more realistic picture of the status quo. Furthermore, they showed that the idea of Silesian identification found an unexpected high number of supporters. This fact indicates an emerging meaning of regional identification amid significant changes of cultural values in Polish society.

  6. Rhetorical, Metacognitive, and Cognitive Strategies in Teacher Candidates’ Essay Writing

    Directory of Open Access Journals (Sweden)

    Claudio Díaz Larenas

    2017-07-01

    Full Text Available This paper reports on a study about the rhetoric, metacognitive, and cognitive strategies pre-service teachers use before and after a process-based writing intervention when completing an argumentative essay. The data were collected through two think-aloud protocols while 21 Chilean English as a foreign language pre-service teachers completed an essay task. The findings show that strategies such as summarizing, reaffirming, and selecting ideas were only evidenced during the post intervention essay, without the use of communication and socio-affective strategies in either of the two essays. All in all, a process-based writing intervention does not only influence the number of times a strategy is used, but also the number of students who employs strategies when writing an essay—two key considerations for the devising of any writing program.

  12. Four essays on market power in energy economics

    Energy Technology Data Exchange (ETDEWEB)

    Hansen, Petter Vegard

    2008-07-01

    Market power in energy markets is discussed intensively in both academic and public arenas. There has been an intense energy debate on market power at least since the Organization of Petroleum Exporting Countries (OPEC) exercised its market power and caused the 'oil crisis' of the 1970s, and again following the deregulation of electricity markets at the beginning of the 1990s. However, this debate is not new. In 1911, for example, the US Supreme Court divided Standard Oil into 34 separate companies using antitrust law. With increasing energy prices and the ongoing process of liberalization of electricity markets throughout the world, the topic is still relevant for future markets. The four essays in this dissertation discuss specific aspects of market power in energy markets. The first essay concerns the crude oil market, and the remaining three essays relate to market power in the Nordic and Norwegian electricity markets. In the first essay, a multi-equation dynamic econometric model tests whether the behaviour of OPEC, as a whole or as different subgroups, is consistent with the behaviour of dominant producers in the world crude oil market. The second essay is a theoretical work that introduces uncertainty in inflow to the discussion of market power in hydropower markets by analysing the effects of uncertainty in inflow on market performance under alternative assumptions about market structure. In the third essay, high-frequency data are used to analyse how price signals from the spot market affect end-user demand in the Norwegian and Swedish electricity markets. Finally, in the fourth essay, retailer and household behaviour in the Norwegian electricity market are analysed using detailed information on prices and other market characteristics. In the following section, I provide highlights from a general discussion of market power in order to set the essays included in this dissertation in context. (Author). refs., figs., tabs

    Lenihan, J; Fletcher, W W [eds.

    1975-01-01

    Exploitation of energy has some impact on the environment. Six essays are presented to examine the variety of problems: (1) Sir Samuel Curran, in Energy and the Needs of Man, concludes that techniques to produce new energy sources will be found, bur conservation and the population explosion must be seriously examined; (2) Dr. Earl Cook, in Flow of Energy Through Technological Society, shows where energy comes from, how it is used and how it returns to the environment; he emphasizes the inefficiency of many energy conversion processes in consequence of the Second law of Thermodynamics; (3) Dr. Andrew Parteous, in Economical Use of Energy and Materials, explains energy not only used in heating, lighting, and transport, but in industry; his accounting of energy shows waste, and he stresses recycling and recovering the energy in domestic waste; (4) Sir Frank McFadzean, in Energy--the International Scene, examines the interplay of economics, technology, and politics in the oil industry; he suggests that more mature international leadership is needed to overcome the current difficulties facing producers and consumers; (5) J. D. Dunster, in The Atom and the Environment, examines the environmental impact of nuclear energy where the safety standards are more strenuous, but are feared more; he is a proponent of nuclear energy, but says an overall energy policy, balancing environmental factors against economic and political considerations, is needed; Dr. B. J. Brinkworth, in Direct Use of Solar Energy, reminds us that the Sun is the ultimate source of energy, and says solar energy can be exploited globally without damaging the environment. (MCW)

  17. Essays on U.S. energy markets

    Science.gov (United States)

    Brightwell, David A.

    2008-04-01

    This dissertation examines three facets of U.S. energy use and policy. First, I examine the Gulf Coast petroleum refining industry to determine the structure of the industry. Using the duality between cost-minimization and production functions, I estimate the demand for labor to determine the underlying production function. The results indicate that refineries have become more capital intensive due to the relative price increase of labor. The industry has consolidated in response to higher labor costs and costs of environmental compliance. Next, I examine oil production in the United States. An empirical model based on the theoretical framework of Pindyck is used to estimate production. This model differs from previous research by using state level data rather than national level data. The results indicate that the production elasticity with respect to reserves and the price elasticity of supply are both inelastic in the long run. The implication of these findings is that policies designed to increase domestic production through subsidies, tax breaks, or royalty reductions will likely provide little additional oil. We simulate production under three scenarios. In the most extreme scenario, prices double between 2005 and 2030 while reserves increase by 50%. Under this scenario, oil production in 2030 is approximately the same as the 2005 level. The third essay estimates demand for fossil fuels in the U.S. and uses these estimates to forecast CO2 emissions. The results indicate that there is almost no substitution from one fossil fuel to another and that all three fossil fuels are inelastic in the long run. Additionally, all three fuels respond differently to changes in GDP. The result of the differing elasticities with respect to GDP is that the energy mix has changed over time. The implication for forecasting CO2 emissions is that models that cannot distinguish changes in the energy mix are not effective in forecasting CO2 emissions.

    2015-03-01

    The anabolic effect of resistance training can mitigate muscle loss during contest preparation. In reviewing relevant literature, we recommend a periodized approach be utilized. Block and undulating models show promise. Muscle groups should be trained 2 times weekly or more, although high volume training may benefit from higher frequencies to keep volume at any one session from becoming excessive. Low to high (~3-15) repetitions can be utilized but most repetitions should occur in the 6-12 range using 70-80% of 1 repetition maximum. Roughly 40-70 reps per muscle group per session should be performed, however higher volume may be appropriate for advanced bodybuilders. Traditional rest intervals of 1-3 minutes are adequate, but longer intervals can be used. Tempo should allow muscular control of the load; 1-2 s concentric and 2-3 s eccentric tempos. Training to failure should be limited when performing heavy loads on taxing exercises, and primarily relegated to single-joint exercises and higher repetitions. A core of multi-joint exercises with some single-joint exercises to address specific muscle groups as needed should be used, emphasizing full range of motion and proper form. Cardiovascular training can be used to enhance fat loss. Interference with strength training adaptations increases concomitantly with frequency and duration of cardiovascular training. Thus, the lowest frequency and duration possible while achieving sufficient fat loss should be used. Full-body modalities or cycling may reduce interference. High intensities may as well; however, require more recovery. Fasted cardiovascular training may not have benefits over fed-state and could be detrimental.

  19. Essays on information disclosure and the environment

    Science.gov (United States)

    Mathai, Koshy

    The essays in this dissertation study information disclosure and environmental policy. The first chapter challenges the longstanding result that firms will, in general, voluntarily disclose information about product quality, in light of the unrealism of the assumption, common to much of the literature, that consumers are identical. When this assumption is relaxed, an efficiency-enhancing role may emerge for disclosure regulation, insofar as it can improve information provision and thus help protect consumers with "moderately atypical" preferences. The paper also endogenizes firms's choice of quality and suggests that disclosure regulation may also raise welfare indirectly, by inducing firms to improve product quality. The second chapter explores the significance of policy-induced technological change (ITC) for the design of carbon-abatement policies. The paper considers both R&D-based and learning-by-doing-based knowledge accumulation, examining each specification under both a cost-effectiveness and a benefit-cost policy criterion. We show analytically that the presence of ITC generally implies a lower profile of optimal carbon taxes, a shifting of abatement effort into the future (in the R&D scenarios), and an increase in the scale of abatement (in the benefit-cost scenarios). Numerical simulations indicate that the impact of ITC on abatement timing is very slight, but the effects on costs, optimal carbon taxes, and cumulative abatement can be large. The third chapter uses a World Bank dataset on Chinese state-owned enterprises to estimate price elasticities of industrial coal demand. A simple coal-demand equation is estimated in many forms, and significant price sensitivity is almost always found: the own-price elasticity is estimated to be roughly -0.5. A cost-function/share-equation system is also estimated, and although the function is frequently ill-behaved, indicating that firms may not be minimizing costs, the elasticity estimates again are large and

    2017-01-01

    Full Text Available The subject known as Programming Contests in the Bachelor’s Degree in Computer Engineering course focuses on solving programming problems frequently met within contests such as the Southwest Europe Regional Contest (SWERC. In order to solve these problems one first needs to model the problem correctly, find the ideal solution, and then be able to program it without making any mistakes in a very short period of time. Leading multinationals such as Google, Apple, IBM, Facebook and Microsoft place a very high value on these abilities when selecting candidates for posts in their companies. In this communication we present some preliminary results of an analysis of the interaction between two optional subjects in the Computer Science Degree course: Programming Contests (PC and Graphs, Models and Applications (GMA. The results of this analysis enabled us to make changes to some of the contents in GMA in order to better prepare the students to deal with the challenges they have to face in programming contests.

  2. Social licence, corporate social responsibility and coal seam gas: framing the new political dynamics of contestation

    International Nuclear Information System (INIS)

    Curran, Giorel

    2017-01-01

    This paper explores the contestation dynamics between the unconventional gas mining sector and its challengers through the prism of the social licence to operate. Social licence is a dominant narrative in the mining sector today and as a signifier of the sector's CSR credentials, the term is an influential one. Its capacity to confer project legitimacy, and hence avoid the risks of community opposition, helps explain why most companies seek to gain one. Today both gas proponents and opponents talk the language of social licence: the former to defend their projects, the latter to challenge them. Yet, beyond rhetoric, the precise meaning of social licence remains elusive. This paper uses a case study of community opposition to primarily coal seam gas projects in an eastern Australian region to explore how the absence of a precise meaning for social licence has created a strategic opportunity space for the industry's opponents to invest social licence with a potent democracy frame. This democracy framing has proved particularly effective as a contestation tool and helps explain the outcomes in this case. - Highlights: • Unconventional gas exploration and mining is becoming increasingly contested. • A key way of managing this contestation is through the social licence to operate. • Both proponents and opponents of gas mining use social licence strategically. • Social licence has become increasingly politicised. • A democratic frame assists the effectiveness of contestation.

  3. Five essays on fiscal policy, intergenerational welfare and petroleum wealth

    1994-12-01

    Motivated by current macro economic problems facing the Norwegian economy, this thesis deals with fiscal policy and the management of petroleum wealth in a small open resource economy. The thesis highlights the fact that considerable parts of the petroleum revenues are collected by the government and studies in particular the interaction between fiscal policy, uncertain petroleum revenues and welfare between generations. Essay 1 is a paper on the calculation of the Norwegian petroleum wealth and surveys economic effects of the development of the petroleum sector and the spending of the petroleum revenues. Essay 2 deals with the effects of uncertain government petroleum revenues on fiscal policy, wealth accumulation and inter generational welfare. In Essay 3 a discussion is given of the effects of oil price risk on international risk sharing. Petroleum importing and exporting countries are considered within OECD-Europe. A possible wealth consumption policy is found to have serious and long-lasting negative effects on the welfare of coming generations, as described in Essay 4. Finally, Essay 5 considers a dynamic dependent economy model extended to incorporate finite horizons of the households and structural adjustment costs in production. 121 refs., 19 figs., 10 tabs.

  5. Duncan Tanner Essay Prize Winner 2014. Against the 'Sacred Cow': NHS Opposition and the Fellowship for Freedom in Medicine, 1948-72.

    Science.gov (United States)

    Seaton, Andrew

    2015-01-01

    This essay recovers organized opposition to the National Health Service (NHS) by considering the Fellowship for Freedom in Medicine (FFM), a conservative organization of doctors who challenged the 'Sacred Cow' of nationalized healthcare in the 1950s and 1960s. While there has been little interest in anti-NHS politics because of shortcomings in the institution's historiography, this study suggests ways a new history of the service can be written. Central to that project is taking the broader ideological and emotive quality of the NHS seriously, and appreciating the way, for all sides of the political spectrum, as well as the general public, the service has always been a contested symbol of post-war British identity. This essay argues that two NHS 'crises'--panics over costs, and disillusionment within general practice--were not merely disagreements over budgets and pay-packets but politically charged moments infused with conservative anxieties over Britain's post-war trajectory. The FFM imagined the NHS as an economically dangerous bureaucratic machine that crushed medical independence and risked pushing the country towards dictatorship. Allies within the Conservative Party, private health insurance industry, and free-market 'think-tanks' worked with the FFM to challenge defences of both the service's operation and meaning. To appreciate why the NHS remains 'the closest thing the English have to a religion', one must consider the apostates as well as the faithful.

    There are effects of sportswear color on the contest outcome. It has been explained from the psychological and perceptual viewpoints, respectively. It was studied by integrating the homeostatic theory of exercise training and autonomic nervous model of color vision in this paper. It was found that the effects of sportswear color on the contest outcome depend on autonomic nervous homeostasis (ANH). Color can be classified into hot color such as red, orange and yellow and cold color such as green, blue and violet. If the athletes have been in ANH, there are no effects of sportswear color on the contest outcome. If the autonomic nervous system is far from ANH due to exercise induced fatigue, wearing cold color had no predominance for cold-hot matches, and wearing white had no predominance for white-color matches.

    Two of the major concerns of the NASA Ames Research Center (NASA ARC) Advisory Committee for Women (ACW) are that recruitment of women scientists, engineers, and technicians needs to increase and that barriers to advancement need to be removed for improved representation of women in middle and upper management and scientific positions. One strategy that addressed this concern was the ACW sponsorship of a Technical Paper Contest for Women at Ames Research Center. Other sponsors of the Contest were the Ames Equal Opportunity Council and the Ames Contractor Council. The Technical Paper Contest for Women greatly increased the visibility of both the civil service women and the women who work for contractors at Ames. The women had the opportunity to hone their written and oral presentation skills. Networking among Ames women increased.

  9. The first mathematical models of dynamic meteorology: The Berlin prize contest of 1746

    Egger, J.; Pelkowski, J. [Muenchen Univ. (Germany). Meteorologisches Inst.

    2008-02-15

    The first models of dynamic meteorology were published in 1747 as a result of a prize contest of the Academy of Prussia. The topic of the contest concerned the determination of the winds 'if the Earth were surrounded everywhere by an ocean'. D'Alembert formulated a shallow water model for the first time in his prize-winning contribution and attempted to calculate tidal motions within the fluid layers. Daniel Bernoulli viewed the atmosphere as a boundary layer wherein the winds rotating with the earth at low elevations have to adjust their motion to a solar atmosphere at large heights. He is first in applying the principle of angular momentum conservation in continuum geophysics when calculating the zonal wind profile. An account of the historical background of the contest is given, as well as some later reactions to d'Alembert's solution. (orig.)

  11. Essays on the economics of decarbonization and renewable energy support

    International Nuclear Information System (INIS)

    Jaegemann, Cosima Claudia

    2014-01-01

    The thesis consists of five essays investigating various aspects associated with the decarbonization of Europe's power sector and the politically incentivized expansion of renewable energy generation. The first essay analyzes the economic implications of alternative decarbonization pathways and policy instruments for Europe's power sector up to 2050 and illustrates the importance of ensuring competition between all low-carbon technologies in order to limit the costs of decarbonization. The second essay analyzes the economic inefficiency associated with the concept of grid parity for the case of photovoltaic (PV). In order to both enhance overall welfare and avoid redistributional effects, the indirect financial incentive for in-house PV electricity consumption should be abolished. The third essay discusses the system price effect of wind and solar power generation and illustrates that the decrease in the marginal value of wind and solar power (as a consequence of increased penetration) is already highly relevant for both wind and solar power generation in Germany. The fourth essay adds to the ongoing debate surrounding the cost-efficient achievement of politically implemented renewable energy targets. Renewable energy support schemes that fail to incentivize investors to account for differences in the marginal value of wind and solar power generation are associated with excess costs as they prevent the equalization of net marginal costs across technologies and regions. The fifth essay analyzes the economic value of storage as a function of the overall generation mix and illustrates the economic inefficiency arising from feed-in tariff systems for the special case of thermal energy storage units in concentrating solar power plants.

  13. Cosmopolitanism and peace in Kant's essay on 'Perpetual Peace'

    DEFF Research Database (Denmark)

    Huggler, Jørgen

    2010-01-01

    Immanuel Kant's essay on Perpetual Peace (1795/96) contains a rejection of the idea of a world government (earlier advocated by Kant himself). In connexion with a substantial argument for cosmopolitan rights based on the human body and its need for a space on the surface of the Earth, Kant presents...... the most rigorous philosophical formulation ever given of the limitations of the cosmopolitan law. In this contribution, Kant's essay is analysed and the reasons he gives for these restrictions discussed in relation to his main focus: to project a realistic path to perpetual peace....

  14. Proposing a Wiki-Based Technique for Collaborative Essay Writing

    2014-10-01

    Full Text Available This paper aims at proposing a technique for students learning English as a foreign language when they collaboratively write an argumentative essay in a wiki environment. A wiki environment and collaborative work play an important role within the academic writing task. Nevertheless, an appropriate and systematic work assignment is required in order to make use of both. In this paper the proposed technique when writing a collaborative essay mainly attempts to provide the most effective way to enhance equal participation among group members by taking as a base computer mediated collaboration. Within this context, the students’ role is clearly defined and individual and collaborative tasks are explained.

  15. Space, Time, Matter, and Form Essays on Aristotle's Physics

    CERN Document Server

    Bostock, David

    2006-01-01

    Space, Time, Matter, and Form collects ten of David Bostock's essays on themes from Aristotle's Physics, four of them published here for the first time. The first five papers look at issues raised in the first two books of the Physics, centred on notions of matter and form, and the idea of substance as what persists through change. They also range over other of Aristotle's scientific works, such as his biology and psychology and the account of change in his De Generatione et Corruptione. The volume's remaining essays examine themes in later books of the Physics, including infinity, place, time

    1981-01-01

    Essays in General Relativity: A Festschrift for Abraham Taub is collection of essays to honor Professor Abraham H. Taub on the occasion of his retirement from the mathematics faculty of the University of California at Berkeley. Relativistic hydrodynamics has always been a subject dear to Taub's heart. In fact, many basic results on special relativistic fluid flows are due to him, and he has been a major contributor to the study of fluid flows near shocks. The book contains 16 chapters and begins with a discussion of a geometrical approach to general relativity. This is followed by separate cha

  17. Research protocol: a realist synthesis of contestability in community-based mental health markets.

    Science.gov (United States)

    Durham, Jo; Bains, Amara

    2015-03-25

    In most developed nations, there has been a shift from public services to a marketisation of public goods and services - representing a significant reform process aiming to transform the way in which community-based human services, such as health, are delivered and consumed. For services, this means developing the capacity to adapt and innovate in response to changing circumstances to achieve quality. The availability of rigorous research to demonstrate whether a market approach and contestability, in particular, is a coherent reform process is largely absent. Contestability operates on the premise that better procurement processes allow more providers to enter the market and compete for contracts. This is expected to create stimulus for greater efficiencies, innovation and improved service delivery to consumers. There is limited understanding, however, about how community-based providers morph and re-configure in response to the opportunities posed by contestability. This study focuses on the effect of a contestability policy on the community-managed mental health sector. A realist review will be undertaken to understand how and why the introduction of contestability into a previously incontestable market influences the ways in which community-based mental health providers respond to contestability. The review will investigate those circumstances that shape organisational response and generate outcomes through activating mechanisms. An early scoping has helped to formulate the initial program theory. A realist synthesis will be undertaken to identify relevant journal articles and grey literature. Data will be extracted in relation to the emerging contextual factors, mechanisms and outcomes and their configurations. The analysis will seek patterns and regularities in these configurations across the extracted data and will focus on addressing our theory-based questions. Increasingly, community-based mental health markets are moving to contestability models. Rigorous

  2. Understanding Fear of Opportunism in Global Prize-Based Science Contests: Evidence for Gender and Age Differences.

    2015-01-01

    Global prize-based science contests have great potential for tapping into diverse knowledge on a global scale and overcoming important scientific challenges. A necessary step for knowledge to be utilized in these contests is for that knowledge to be disclosed. Knowledge disclosure, however, is paradoxical in nature: in order for the value of knowledge to be assessed, inventors must disclose their knowledge, but then the person who receives that knowledge does so at no cost and may use it opportunistically. This risk of potential opportunistic behavior in turn makes the inventor fearful of disclosing knowledge, and this is a major psychological barrier to knowledge disclosure. In this project, we investigated this fear of opportunism in global prize-based science contests by surveying 630 contest participants in the InnoCentive online platform for science contests. We found that participants in these science contests experience fear of opportunism to varying degrees, and that women and older participants have significantly less fear of disclosing their scientific knowledge. Our findings highlight the importance of taking differences in such fears into account when designing global prize-based contests so that the potential of the contests for reaching solutions to important and challenging problems can be used more effectively.

    .S. Department of Energy's National Laboratories, and provide the first quantitative evidence that technology transfer agreements at the Labs lead to greatly increased rates of innovation spillovers. This chapter also makes a key methodological contribution by introducing a technique to utilize automated text analysis in an empirical matching design that is broadly applicable to other types of social science studies. This work has important implications for how policies should be designed to maximize the social benefits of the $125 billion in annual federal funding allocated to research and development and the extent to which private firms can benefit from technology partnerships with the government. The final chapter of this dissertation explores the effectiveness of international policy to facilitate the deployment of low-emitting energy technologies in developing countries. Together with Joern Huenteler, I examine wind energy deployment in China supported through international climate finance flows under the Kyoto Protocol's Clean Development Mechanism. Utilizing a project-level financial model of wind energy projects parameterized with high-resolution observations of Chinese wind speeds, we find that the environmental benefits of projects financed under the Clean Development Mechanism are substantially lower than reported, as many Chinese wind projects would have been built without the Mechanism's support, and thus do not represent additional clean energy generation. Together, the essays in this dissertation suggest several limitations of energy technology innovation policy and areas for reform. Public funds for energy research and development could be made more effective if decision making approaches were better grounded in available technical expertise and developed in framework that captures the important interactions of technologies in a research and development portfolio. The first chapter of this dissertation suggests a politically feasible path towards this type of

    tuneable lasers, generally with the emphasis on understanding the underlying physics rather than accumulating data. He had a highly original mind, which showed both in his choice of research topics and in his method of approach. He did not follow fashion; his instinct for an interesting problem was at odds with the modem policy of direct funding and the identification of "growth areas". His applications for research grants were often unsuccessful, despite his high international standing and integrity. He was never interested in building up a large research team, and had comparatively few research students, but his enthusiasm and commitment to the quality of his science attracted a succession of overseas visitors to his laboratory. Following my own year at the Clarendon, and some subsequent visits both to Oxford and to Reading, there was a continuing strong association between the Clarendon and Otago Physics that continues until today. George Series was the William Evans Visiting Professor to Otago University in 1972. He never lost his interest in the fundamentals of physics inspired by his first researches into the structure of the hydrogen atom; he wrote on the Rydberg constant, the physics of spontaneous emission, and on the fine-structure constant α = e2/hc. He donated a garden seat to St Edmund Hall (Oxford), of which he was a Fellow. On it he placed a plaque* in recognition of the ubiquitous nature of this constant; it almost had magical significance for him. He served physics in many ways outside research. He was for a number of years the Editor of the European Journal of Physics and was also Editor of the Journal of Physics B: Atomic and Molecular Physics, He was also on the Editorial Board of a number of journals. He was elected to Fellowship of a number of physics societies. The Editorial Board of these Memorial Essays dedicate them to George's memory, and to his wife Annette and his family.

  9. Evidence for the influence of the mere-exposure effect on voting in the Eurovision Song Contest

    Directory of Open Access Journals (Sweden)

    Diarmuid B. Verrier

    2012-09-01

    Full Text Available The mere exposure, or familiarity, effect is the tendency for people to feel more positive about stimuli to which they have previously been exposed. The Eurovision Song Contest is a two-stage event, in which some contestants in the final will be more familiar to viewers than others. Thus, viewers' voting is likely to be influenced by this effect. Previous work attempting to demonstrate this effect in this context has been unable to control for contestant quality. The current study, which used a novel procedure to analyse the way in which contestant countries distributed their points (a function of how viewers voted in those countries between 2008 and 2011, showed that contestants did better if they previously appeared in a semifinal that was seen by voters. This is evidence that the mere exposure effect, alongside previously studied factors such as cultural and geographical closeness, influences the way viewers vote in the Eurovision.

  19. Source-Based Tasks in Writing Independent and Integrated Essays

    Directory of Open Access Journals (Sweden)

    Javad Gholami

    2017-07-01

    Full Text Available Integrated writing tasks have gained considerable attention in ESL and EFL writing assessment and are frequently needed and used in academic settings and daily life. However, they are very rarely practiced and promoted in writing classes. This paper explored the effects of source-based writing practice on EFL learners’ composing abilities and investigated the probable differences between those tasks and independent writing ones in improving Iranian EFL learners’ essay writing abilities. To this end, a quasi-experimental design was implemented to gauge EFL learners’ writing improvements using a pretest-posttest layout. Twenty female learners taking a TOEFL iBT preparation course were randomly divided into an only-writing group with just independent writing instruction and essay practice, and a hybrid-writing-approach group receiving instruction and practice on independent writing plus source-based essay writing for ten sessions. Based on the findings, the participants with hybrid writing practice outperformed their counterparts in integrated essay tests. Their superior performance was not observed in the case of traditional independent writing tasks. The present study calls for incorporating more source-based writing tasks in writing courses.

    Full Text Available Due to the need of showing the reliability of results from biological essays, such as in health and environmental areas, laboratories have been implementing quality systems, particularly ABNT NBR ISO/IEC 17025 (ABNT, 2001, which include as one of the requirements, the calculation of uncertainty in essays results. It is of common knowledge that estimating uncertainty in essays using organisms, such as animal and vegetal species, is difficult, preventing from meeting that requirement in the standard. The paper shows the calculation of uncertainties in influences quantities in these essays as a tool to allow validating the measuring process, by using the essays performed by Rhodia Environmental Impact Analysis Laboratory and IPEN Ecotoxicology Laboratory as examples.Devido à necessidade de demonstrar a confiabilidade dos resultados de ensaios biológicos como, por exemplo, nas áreas de saúde e ambiental, laboratórios vêm implementando sistemas da qualidade, em especial a ABNT NBR ISO/IEC 17025 (ABNT, 2001 que inclui como um dos requisitos o cálculo da incerteza dos resultados dos ensaios.

    2013-09-01

    Often, economic decisions do not only depend on one's own preferences, but also on the choices of others and therefore require strategizing (i.e., thinking about what others might think). In experimental economics, this has been modeled by the beauty contest game. Another typical feature of economic decisions is that they are often carried out under stress. Therefore, in the present study, we aimed to examine the influence of stress on decision-making in the beauty contest game. Participants were randomly assigned to either the Trier Social Stress Test for Groups (TSST-G) or a placebo version of the TSST-G (control condition). Then, participants played four rounds of a standard beauty contest game. As a biomarker of stress, salivary cortisol was measured. As predicted, participants under stress chose higher numbers in the beauty contest game than non-stressed participants, indicating less strategizing. This effect was mediated by the stress-induced increase in cortisol. Copyright © 2013 Elsevier Ltd. All rights reserved.

    2017-05-03

    Physicians in both Western and Eastern countries are being confronted by changes in health care delivery systems and medical professionalism values. The traditional concept of "In-Sul" (benevolent art) and the modern history of South Korea have led to cultural differences between South Korea and other countries in conceptualizing medical professionalism; thus, we studied medical students' perceptions of professionalism as described in essays written on this topic. In 2014, we asked 109 first-year medical students who were enrolled in a compulsory ethics course to anonymously write a description of an instance of medical professionalism that they had witnessed, as well as reflecting on their own professional context. We then processed 105 valid essays using thematic content analysis with computer-assisted qualitative data analysis software. Thematic analysis of the students' essays revealed two core aspects of professionalism in South Korea, one focused on respect for patients and the other on physicians' accountability. The most common theme regarding physician-patient relationships was trust. By contrast, distributive justice was thought to be a non-essential aspect of professionalism. In Western countries, physicians tend to promote justice in the health care system, including fair distribution of medical resources; however, we found that medical students in South Korea were more inclined to emphasize doctors' relationships with patients. Medical educators should develop curricular interventions regarding medical professionalism to meet the legitimate needs of patients in their own culture. Because professionalism is a dynamic construct of culture, medical educators should reaffirm cultural context-specific definitions of professionalism for development of associated curricula.

  18. The Effects of Ocean Acidification on Feeding and Contest Behaviour by the Beadlet Anemone Actinia equina

    Science.gov (United States)

    Bamber, Tess Olivia; Jackson, Angus Charles; Mansfield, Robert Philip

    2018-05-01

    Increasing concentrations of atmospheric carbon dioxide are causing oceanic pH to decline worldwide, a phenomenon termed ocean acidification. Mounting experimental evidence indicates that near-future levels of CO2 will affect calcareous invertebrates such as corals, molluscs and gastropods, by reducing their scope for calcification. Despite extensive research into ocean acidification in recent years, the effects on non-calcifying anthozoans, such as sea anemones, remain little explored. In Western Europe, intertidal anemones such as Actinia equina are abundant, lower trophic-level organisms that function as important ecosystem engineers. Changes to behaviours of these simple predators could have implications for intertidal assemblages. This investigation identified the effects of reduced seawater pH on feeding and contest behaviour by A. equina. Video footage was recorded for A. equina feeding at current-day seawater (pH 8.1), and the least (pH 7.9) and most (pH 7.6) severe end-of-century predictions. Footage was also taken of contests over ownership of space between anemones exposed to reduced pH and those that were not. No statistically significant differences were identified in feeding duration or various aspects of contest behaviour including initiating, winning, inflating acrorhagi, inflicting acrorhagial peels and contest duration. Multivariate analyses showed no effect of pH on a combination of these variables. This provides contrast with other studies where anemones with symbiotic algae thrive in areas of natural increased acidity. Thus, novel experiments using intraspecific contests and resource-holding potential may prove an effective approach to understand sub-lethal consequences of ocean acidification for A. equina, other sea anemones and more broadly for marine ecosystems.

  2. The Effects of Residency and Body Size on Contest Initiation and Outcome in the Territorial Dragon, Ctenophorus decresii

    Science.gov (United States)

    Umbers, Kate D. L.; Osborne, Louise; Keogh, J. Scott

    2012-01-01

    Empirical studies of the determinants of contests have been attempting to unravel the complexity of animal contest behaviour for decades. This complexity requires that experiments incorporate multiple determinants into studies to tease apart their relative effects. In this study we examined the complex contest behaviour of the tawny dragon (Ctenophorus decresii), a territorial agamid lizard, with the specific aim of defining the factors that determine contest outcome. We manipulated the relative size and residency status of lizards in contests to weight their importance in determining contest outcome. We found that size, residency and initiating a fight were all important in determining outcomes of fights. We also tested whether residency or size was important in predicting the status of lizard that initiated a fight. We found that residency was the most important factor in predicting fight initiation. We discuss the effects of size and residency status in context of previous studies on contests in tawny dragons and other animals. Our study provides manipulative behavioural data in support of the overriding effects of residency on initiation fights and winning them. PMID:23077558

  4. Essays on pricing electricity and electricity derivatives in deregulated markets

    Science.gov (United States)

    Popova, Julia

    2008-10-01

    This dissertation is composed of four essays on the behavior of wholesale electricity prices and their derivatives. The first essay provides an empirical model that takes into account the spatial features of a transmission network on the electricity market. The spatial structure of the transmission grid plays a key role in determining electricity prices, but it has not been incorporated into previous empirical models. The econometric model in this essay incorporates a simple representation of the transmission system into a spatial panel data model of electricity prices, and also accounts for the effect of dynamic transmission system constraints on electricity market integration. Empirical results using PJM data confirm the existence of spatial patterns in electricity prices and show that spatial correlation diminishes as transmission lines become more congested. The second essay develops and empirically tests a model of the influence of natural gas storage inventories on the electricity forward premium. I link a model of the effect of gas storage constraints on the higher moments of the distribution of electricity prices to a model of the effect of those moments on the forward premium. Empirical results using PJM data support the model's predictions that gas storage inventories sharply reduce the electricity forward premium when demand for electricity is high and space-heating demand for gas is low. The third essay examines the efficiency of PJM electricity markets. A market is efficient if prices reflect all relevant information, so that prices follow a random walk. The hypothesis of random walk is examined using empirical tests, including the Portmanteau, Augmented Dickey-Fuller, KPSS, and multiple variance ratio tests. The results are mixed though evidence of some level of market efficiency is found. The last essay investigates the possibility that previous researchers have drawn spurious conclusions based on classical unit root tests incorrectly applied to

  5. Three Essays Examining Household Energy Demand and Behavior

    Science.gov (United States)

    Murray, Anthony G.

    This dissertation consists of three essays examining household energy decisions and behavior. The first essay examines the adoption of energy efficient Energy Star home appliances by U.S. households. Program effectiveness requires that consumers be aware of the labeling scheme and also change their purchase decisions based on label information. The first essay examines the factors associated with consumer awareness of the Energy Star label of recently purchased major appliances and the factors associated with the choice of Energy Star labeled appliances. The findings suggest that eliminating identified gaps in Energy Star appliance adoption would result in house electricity cost savings of $164 million per year and associated carbon emission reductions of about 1.1 million metric tons per year. The second essay evaluates household energy security and the effectiveness of the Low-Income Home Energy Assistance Program (LIHEAP), the single largest energy assistance program available to poor households within the United States. Energy security is conceptually akin to the well-known concept of food security. Rasch models and household responses to energy security questions in the 2005 Residential Energy Consumption Survey are used to generate an energy insecurity index that is consistent with those found in the food insecurity literature. Participating in LIHEAP is found to significantly reduce household energy insecurity score in the index. Further, simulations show that the elimination of the energy assistance safety net currently available to households increases the number of energy insecure house- holds by over 16 percent. The third essay develops a five equation demand system to estimate household own-price, cross-price and income elasticities between electricity, natural gas, food at home, food away from home, and non-durable commodity groups. Household cross-price elasticities between energy and food commodities are of particular importance. Energy price shocks

  6. Essays on alternative energy policies affecting the US transportation sector

    Science.gov (United States)

    O'Rear, Eric G.

    This dissertation encompasses three essays evaluating the impacts of different policies targeting the greenhouse gas (GHG) emissions, fuel demands, etc. of the transportation sector. Though there are some similarities across the three chapters, each essay stands alone as an independent work. The 2010 US EPA MARKAL model is used in each essay to evaluate policy effects. Essay 1 focuses on the recent increases in Corporate Average Fuel Economy (CAFE) standards, and the implications of a "rebound effect." These increases are compared to a carbon tax generating similar reductions in system-wide emissions. As anticipated, the largest reductions in fuel use by light-duty vehicles (LDV) and emissions are achieved under CAFE. Consideration of the rebound effect does little to distort CAFE benefits. Our work validates many economists' belief that a carbon tax is a more efficient approach. However, because the tax takes advantage of cheaper abatement opportunities in other sectors, reductions in transportation emissions will be much lower than what we observe with CAFE. Essay 2 compares CAFE increases with what some economists suggest would be a much more "efficient" alternative -- a system-wide oil tax internalizing some environmental externalities. Because oil taxes are likely to be implemented in addition to CAFE standards, we consider a combined policy case reflecting this. Our supplementary analysis approximates the appropriate tax rates to produce similar reductions in oil demands as CAFE (CAFE-equivalent tax rates). We discover that taxes result in greater and more cost-effective reductions in system-wide emissions and net oil imports than CAFE. The current fuel tax system is compared to three versions of a national vehicle miles traveled (VMT) tax charged to all LDVs in Essay 3. VMT taxes directly charge motorists for each mile driven and help to correct the problem of eroding tax revenues given the failure of today's fuel taxes to adjust with inflation. Results

  7. Engaging Earth- and Environmental-Science Undergraduates Through Weather Discussions and an eLearning Weather Forecasting Contest

    For students who major in meteorology, engaging in weather forecasting can motivate learning, develop critical-thinking skills, improve their written communication, and yield better forecasts. Whether such advances apply to students who are not meteorology majors has been less demonstrated. To test this idea, a weather discussion and an eLearning weather forecasting contest were devised for a meteorology course taken by third-year undergraduate earth- and environmental-science students. The discussion consisted of using the recent, present, and future weather to amplify the topics of the week's lectures. Then, students forecasted the next day's high temperature and the probability of precipitation for Woodford, the closest official observing site to Manchester, UK. The contest ran for 10 weeks, and the students received credit for participation. The top students at the end of the contest received bonus points on their final grade. A Web-based forecast contest application was developed to register the students, receive their forecasts, and calculate weekly standings. Students who were successful in the forecast contest were not necessarily those who achieved the highest scores on the tests, demonstrating that the contest was possibly testing different skills than traditional learning. Student evaluations indicate that the weather discussion and contest were reasonably successful in engaging students to learn about the weather outside of the classroom, synthesize their knowledge from the lectures, and improve their practical understanding of the weather. Therefore, students taking a meteorology class, but not majoring in meteorology, can derive academic benefits from weather discussions and forecast contests. Nevertheless, student evaluations also indicate that better integration of the lectures, weather discussions, and the forecasting contests is necessary.

    Full Text Available This quantitative quasi-experimental study, which followed a pretest-posttest-delayed posttest design, was aimed at investigating the effect of individualized technology-mediated feedback (henceforth, ITMF on the overall quality of Iranian EFL learners’ argumentative essays. The effect of ITMF, as the experimental treatment, was compared with the common written corrective feedback (henceforth, CWCF strategies as the control treatment. 57 learners, studying at general EFL courses at upper-intermediate level, formed the participants. They were assigned to two groups: ITMF and CWCF, which, in this study, is meant as the pen-and-paper form of direct and indirect feedback. Each group received six sessions of treatment. The writing tasks and tests were all of argumentative type. First, whether there was any significant difference between the ITMF and CWCF in the overall quality of the essays was investigated. The ITMF group significantly outperformed the CWCF one. Then, whether the difference between the groups varied over time was explored, and it was revealed that the ITMF was still significantly superior over the CWCF. Next, whether there would be any significant change in the ITMF in the long term was examined, and no change was seen. The study supports the advocates of screencasting feedback, revision and teacher-learner negotiation following the feedback.

  9. Essays on environmental regulations in electricity markets

    Science.gov (United States)

    Sun, Yanming

    Reducing the Greenhouse Gas pollution and promoting energy efficiency among consumers' energy use have been major public policy issues recently. Currently, both the United States and the European Union have set up explicit percentage requirements that require energy generators or consumers to undertake a certain percentage of their energy production or consumption from renewable sources. To achieve their renewable targets, the Tradable Green Certificates (TGC) system has been introduced in their electricity markets. Moreover, in order to promote energy conservation and achieve energy efficiency targets, price policies and price changes derived from environmental regulations have played a more important role in reducing electricity consumption. My research studies problems associated with these policy implementations. In Chapter 1, I analyze a competitive electricity market with two countries operated under a common TGC system. By using geometric illustrations, I compare the two countries' welfare when the renewable quota is chosen optimally under the common certificate market with three different situations. The policy recommendation is that when the value of damage parameter is sufficiently small, full integration with a TGC market is welfare superior to full integration of an all fossil-fuel based market with an optimal emissions standard. In Chapter 2, by analyzing a stylized theoretical model and numerical examples, I investigate the performance of the optimal renewables policy under full separation and full integration scenarios for two countries' electricity markets operated under TGC systems. In my third chapter, I look at residential electricity consumption responsiveness to increases of electricity price in the U.S. and the different effect of a price increase on electricity use for states of different income levels. My analysis reveals that raising the energy price in the short run will not give consumers much incentive to adjust their appliances and make

    Full Text Available An American minister’s outrage over a celebration of the dropping of the atomic bombs on Japan led to a generous gift of school supplies for students at a primary school in Hiroshima City. In gratitude, students at this school sent dozens of drawings and paintings to the minister’s church. This exchange was inspired by the minister’s Unitarian faith and moral decency and realized through the generosity of his parishioners. But the Japanese children’s artwork can be read in several other ways that greatly complicate the story and implicate Cold War narratives of victory and defeat as well as powerful memories of the destruction, death, and suffering caused by the war.

I should like to mention another curious thing about Bob, namely he had a special talent of finding persuasive arguments that went his way. It was difficult to argue with Bob because it was so difficult to win. Generally quiet otherwise, he was too good and too methodical a debater. I had never seen him losing a debate on a policy issue or in a committee setting. However, when it comes to physics, his soft spot, he occasionally let go some weakness. When so doing, he would lose the debate, but his grin revealed that the loss was more than compensated by the physics he gained together with his debater. It is hard to believe that the office around the corner is now empty. The dear colleague we have come to know, to talk to, and to seek advice from, together with the feet-on-the-desk posture and the familiar grin, are no longer there. I wonder, who will now occupy that office next? And who will continue to carry on Bob Siemann's legacy? Many of us are waiting.

  17. Essays on the behavior of the oil market and OPEC

    Science.gov (United States)

    Algudhea, Salim

    This dissertation consists of three essays. The first essay is mainly concerned with investigating the risk-responsive behavior of OPEC members. Economic theory suggests that producers respond to the risk of volatile price by lowering production level. In the case of OPEC, the risk of the volatility in the price of crude oil does not seem to be a key determinant in the production decision-making process. Engineering constraints, data frequency, and political consideration may be the main causes of such a result. In the second essay, we tested the presence of the asymmetric adjustment in the cheating behavior as a result of crude oil price shocks. We utilize a set of cointegration and error correction methods that do not assume a linear adjustment to test whether cheaters within OPEC respond more to positive or negative crude oil price shocks. We conclude that cheaters respond more to negative shocks than positive shocks in oil price. The inelastic nature of demand for oil seems to play a crucial role in such asymmetric behavior. When there is a negative price shock, OPEC producers compensate for the loss in revenue by overproducing (i.e. cheat). Yet, if there is a positive shock in the price of crude oil, OPEC producers have less incentive to overproduce because of the inelastic demand for oil. The third essay is concerned with testing for the asymmetric adjustment in gasoline prices in the U.S. We consider a Momentum Threshold Autoregressive (MTAR) process to test for the asymmetric adjustment in all of the possible stages that a gallon of gasoline goes through in order to find the source of asymmetry. Then, we examine the dynamics of gasoline prices using asymmetric error correction models based on the MTAR specifications. We find the asymmetric adjustment present in all stages. The asymmetry in the retail stage seems to be the result of insufficient demand faced by retailers.

  7. Three essays on the exploration for non-renewable resources

    International Nuclear Information System (INIS)

    Sadorsky, P.A.

    1990-06-01

    A new additional motive for exploration activity is proposed in the first essay. When exploration occurs before the resource is extracted, there is an incentive to use exploration activity as a strategic instrument to capture market share and inflict capital losses on rivals. This provides an incentive for governments to use strategic taxation to capture greater rents from the imperfectly competitive world output markets. Analytic expressions for the optimal domestic extraction tax and exploration subsidy are presented. In the second essay, Canadian data are used to estimate a multiple-output translog exploration cost function. A new definition of depletion is introduced and its estimated coefficient is found to be statistically significant. Monte Carlo integration techniques were applied to ensure the estimated cost function satisfies concavity and monotonicity. The fitted cost function parameters are then used to estimate the marginal cost of oil and gas exploration. These estimates are used, along with estimates of exploration rents, to measure resource scarcity. In the third essay, Canadian data are used to estimate a stochastic and dynamic model of oil exploration and extraction in Alberta. The main determinants of current period extraction are one period lagged extraction and one period expected extraction. The main determinants of current period exploration are one period lagged cumulative exploration and a relative price variable. 150 refs., 13 figs., 19 tabs

    2012-09-01

    The present study explored different approaches for automatically scoring student essays that were written on the basis of multiple texts. Specifically, these approaches were developed to classify whether or not important elements of the texts were present in the essays. The first was a simple pattern-matching approach called "multi-word" that allowed for flexible matching of words and phrases in the sentences. The second technique was latent semantic analysis (LSA), which was used to compare student sentences to original source sentences using its high-dimensional vector-based representation. Finally, the third was a machine-learning technique, support vector machines, which learned a classification scheme from the corpus. The results of the study suggested that the LSA-based system was superior for detecting the presence of explicit content from the texts, but the multi-word pattern-matching approach was better for detecting inferences outside or across texts. These results suggest that the best approach for analyzing essays of this nature should draw upon multiple natural language processing approaches.

    There is a paucity of research on whether application essays are a valid indicator of medical students' future performance. The goal is to score medical school application essays systematically and examine the correlations between these essay scores and several indicators of student performance during medical school and internship. A journalist created a scoring rubric based on the journalism literature and scored 2 required essays of students admitted to our university in 1 year (N = 145). We picked 7 indicators of medical school and internship performance and correlated these measures with overall essay scores: preclinical medical school grade point average (GPA), clinical medical school GPA, cumulative medical school GPA, U.S. Medical Licensing Exam (USMLE) Step 1 and 2 scores, and scores on a program director's evaluation measuring intern professionalism and expertise. We then examined the Pearson and Spearman correlations between essay scores and the outcomes. Essay scores did not vary widely. American Medical College Application Service essay scores ranged from 3.3 to 4.5 (M = 4.11, SD = 0.15), and Uniformed Services University of the Health Sciences essay scores ranged from 2.9 to 4.5 (M = 4.09, SD = 0.17). None of the medical school or internship performance indicators was significantly correlated with the essay scores. These findings raise questions about the utility of matriculation essays, a resource-intensive admission requirement.

  12. Essays on energy, equity, and the environment in developing countries

    Science.gov (United States)

    Israel, Debra Kim

    1999-11-01

    The essays in this dissertation explore different environmental and public policy issues relevant to developing countries. Essay I examines household-level survey responses to the question "How willing would you be to pay somewhat higher taxes to the government if you knew the money would be spent to protect the environment and prevent land, water and air pollution?" Specifically, for twelve developing and three developed countries included in the survey, the empirical relationships among willingness to pay for environmental quality, relative household income and national income are investigated. The results indicate that when the effects of household and national income are combined, households with below-average income in low-income countries are less willing to pay for environmental protection than those with above-average income in high-income countries. Furthermore, willingness to pay for environmental protection increases more significantly with relative household income than with national income. Essay II uses data from urban Bolivia to study the determinants of household fuel choice, an important link between deforestation and indoor air pollution in developing countries. In particular, the effects of fixed fuel costs, income growth, and female earned income on household fuel choice are examined. The results imply that reduction in firewood use in developing countries is not likely to occur simply as the result of income growth. The essay discusses possible policy implications based on the results that fixed fuel costs appear to be a deterrent to switching to a cleaner fuel and households with female earned income seem less likely to use firewood than other households. Essay III analyzes the equity implications of the elimination of fuel subsidies in the 1985 Bolivian economic reforms. An analysis of the direct static burden shows that while the elimination of gasoline subsidies was progressively distributed, the elimination of LPG and kerosene subsidies

  13. Contested spacing: International non-profit organizations and the mobility of asylum seekers

    DEFF Research Database (Denmark)

    Albu, Oana Brindusa

    The importance of examining space from an organizational standpoint is timely, not the least because the use of this concept has critical and often unintended social, and political effects (Mengis, Nicolini & Gorli, 2016). The global refugee crisis following the post-2015 Syrian conflict is perhaps...... one indicative situation of the highly contested ways in which international non-profit organizations (INGOs) create spaces for their organizational activities (e.g., build informal settlements to provide emergency aid), and thus affect how individuals (e.g., asylum seekers) get re-settled, confined...... to, or even restricted from living in such spaces. These matters are relevant since in the contexts where both the opportunities to move freely and being at peace are challenged, space is not only a neutral structure in which such contested organizing takes place (Mengis et al., 2016). Rather...

    Directory of Open Access Journals (Sweden)

    Bolman Filip V.

    2007-01-01

    Full Text Available Since the first annual Eurovision Song Contest in 1956, politics and popularity have intersected to influence the ways in which Eurovision songs have reflected the complex forms of European nationalism. With the Eurovision victory of Marija Šerifović’s ′Molitva′ at the 52nd Eurovision in Helsinki the politics of regionalism and nationalism fully enveloped Southeastern Europe, creating the impression that old and new European alignments, from Habsburg nostalgia to an emerging Balkan brotherhood, overwhelmed the criteria that would otherwise mean that the grand prix would go to the best song. Taking Marija Šerifović’s ′Molitva′ 2007 as a point of departure, this article examines the extremely complex set of networks that intersect at the Eurovision Song Contest and the national rituals and competitions that transform the power and pleasure driving European popular song in the twenty-first century.

  15. Peroxide accumulation and cell death in filamentous fungi induced by contact with a contestant.

    Science.gov (United States)

    Silar, Philippe

    2005-02-01

    Podospora anserina and Coprinopsis cinerea (syn. Coprinus cinereus) are endowed with a defence system able to differentiate self vs. non-self and involving the generation of peroxide. Indeed, they produce peroxide when confronted with a filamentous fungus, only in non-self confrontations. Both species are not able to recognize yeasts and show a differential response to bacteria. The accumulation of peroxides in the ascomycete Podospora anserina requires an NADPH oxidase and a MAP kinase cascade, previously shown to be involved in fruit body formation, cell differentiation and cell degeneration. Confrontation is accompanied by the death of the contestant hyphae only in specific combinations of species. As in animals and plants, data suggest that peroxide is likely involved in signalling rather than playing a direct toxic role. Fungi display more complex behaviours than generally acknowledged, i.e. they are able to recognize potential contestants and built up defence reactions involving evolutionary conserved enzymes.

  16. Privacy is an essentially contested concept: a multi-dimensional analytic for mapping privacy

    Science.gov (United States)

    Koopman, Colin; Doty, Nick

    2016-01-01

    The meaning of privacy has been much disputed throughout its history in response to wave after wave of new technological capabilities and social configurations. The current round of disputes over privacy fuelled by data science has been a cause of despair for many commentators and a death knell for privacy itself for others. We argue that privacy’s disputes are neither an accidental feature of the concept nor a lamentable condition of its applicability. Privacy is essentially contested. Because it is, privacy is transformable according to changing technological and social conditions. To make productive use of privacy’s essential contestability, we argue for a new approach to privacy research and practical design, focused on the development of conceptual analytics that facilitate dissecting privacy’s multiple uses across multiple contexts.

    Full Text Available After almost two decades of violent conflict in eastern Democratic Republic of the Congo (DRC – during which time the Virunga National Park was focused mainly on 'mere survival' – nature conservation practices in the Park began following strategies of re-enclosure in 2003. These practices are being contested by local population groups using a variety of different strategies. While local and trans-local elites employ more overt, explicit forms of (political contestation, peasants resort to 'weapons of the weak', engaging in more covert, implicit forms of everyday resistance, whereby the customary mode of organising access to land works –among other functions– as a vehicle for resistance. This paper argues that this multi-dimensional resistance ties in with general conflict dynamics in eastern DRC, while at the same time reproducing them within the realm of nature conservation, tightly interwoven with global dynamics.

    The purpose of this study was to plan health education efforts that integrate the health and education sectors. From March to November 2004, an art contest was held for 7th-9th grade students in 109 schools in 11 of Argentina's provinces. The contest allowed improvements in knowledge to be measured and adjustments to be made to the curriculum. The students created works of art featuring tuberculosis. To evaluate knowledge acquired, two provinces were chosen at random. Student knowledge had increased from 67.2% to 96.4%. The administrators and teachers testified to the usefulness of the materials developed. These results show that when the efforts of health and education sectors are coordinated and the appropriate materials are leveraged, the efforts of educators can be substantially bolstered.

    Full Text Available Background Territory owners usually defeat intruders. One explanation for this observation is the uncorrelated asymmetry hypothesis which argues that contests might be settled by an arbitrary convention such as “owners win.” We studied the effect of territorial residency on contest asymmetries in the white-eared hummingbird (Hylocharis leucotis in a fir forest from central Mexico. Methods Twenty white-eared male adult hummingbird territories were monitored during a winter season, recording the territorial behavior of the resident against intruding hummingbirds. The size and quality of the territory were related to the probability that the resident would allow the use of flowers by the intruder. Various generalized models (logistical models were generated to describe the probabilities of victory for each individual resident depending on the different combinations of three predictor variables (territory size, territory quality, and intruder identity. Results In general, small and low quality territory owners tend to prevent conspecific intruders from foraging at a higher rate, while they frequently fail to exclude heterospecific intruders such as the magnificent hummingbird (Eugenes fulgens or the green violetear hummingbird (Colibri thalassinus on any territory size. Our results showed that the identity of the intruder and the size and quality of the territory determined the result of the contests, but not the intensity of defense. Discussion Initially, the rule that “the resident always wins” was supported, since no resident was expelled from its territory during the study. Nevertheless, the resident-intruder asymmetries during the course of a day depended on different factors, such as the size and quality of the territory and, mainly, the identity of the intruders. Our results showed that flexibility observed in contest tactics suggests that these tactics are not fixed but are socially plastic instead and they can be adjusted to
