    2010-01-01

    Promoting equal opportunities at CERN and advising the Director-General on all related matters is the task of the Equal Opportunities Officer, Doris Chromek-Burckhart, and Tim Smith, chair of the Equal Opportunities Advisory Panel. Changes are being introduced: in future, the focus of their work will be broadened to cover all aspects of diversity promotion.   The term "equal opportunities" has always been broader in scope than the equal treatment of men and women but this is what it has traditionally been confined to in practice. "We wanted to change how people see our mission", explains Doris Chromek-Burckhart. The word "diversity" has much wider connotations than "equal opportunities" and makes it clearer that we are also dealing with differences in nationality, religion, age, culture and physical ability”. Getting away from the old clichés is vital to ensuring equal treatment for everyone. The diversit...

    The model of sexual selection under parental choice has been proposed to account for the control that parents exercise over their children's mating decisions. The present paper attempts to formalize and advance this model with the purpose of providing a better understanding of how parental choice mandates the course of sexual selection. In particular, in the proposed formulation, free mate choice involves an opportunity cost which motivates parents to place their children's mate choices under their control. When they succeed in doing so, they become a significant sexual selection force, as traits that appeal to parents in an in-law are selected and increase in frequency in the population. The degree of parental control over mating, and thus the strength of sexual selection under parental choice, is positively predicted by the size of the opportunity cost of free mate choice. The primary factors that affect the level of opportunity cost vary between society types, affecting the strength of parental choice as a sexual selection force.

  7. Equality of Opportunity, Cultural Diversity and Claims for Fairness

    Directory of Open Access Journals (Sweden)

    Mitja Sardoč

    2016-06-01

    Full Text Available The present paper examines some of the tensions, problems and challenges associated with claims for equality of opportunity (the fairness argument. The introductory part identifies three separate forms of justification for public education, including the argument associated with equality of opportunity. Part II examines in detail two questions that reveal part of the anatomy of equality of opportunity: (1 what an opportunity is, and (2 when individuals’ opportunities are equal. This is followed by a presentation of the two basic principles of equality of opportunity: (1 the principle of non-discrimination, and (2 the “levelling the playing field” principle. The next part takes up the multiculturalist hypothesis advanced by minority groups for the accommodation and recognition of cultural diversity. This is followed by the identification of a set of claims comprising the “fairness argument”. The last section focuses on the “currency problem” associated with cultural diversity as a form of “unfair disadvantage”. Part V examines two of the major shortcomings associated with the multicultural conception of equality of opportunity, while the concluding part discusses some of the questions that must be answered by any conception of equal opportunities.

  8. Diversity of Communications, Diversity of Communities: Strategic Choices for Maximum Engagement

    Bartel, B. A.; Unger, M.

    2017-12-01

    One of the challenges around the edges of scientific research is finding ways to effectively communicate about that research beyond the confines of a highly specialized scientific community. While peer-review, publication, and scientific conferences and workshops allow scientists to effectively share their research with colleagues in their field, these exclusive communications do little to reach outside of those circles. Amid increasing requirements to demonstrate the value of research, and threats to funding of both basic and applied research, it becomes increasingly important for scientists and those in fields related to science communications to find, and continually update, tools for effectively reaching broad audiences. Drawing on experiences in science communications from various entities including the National Center for Atmospheric Research, UNAVCO, and the National Snow and Ice Data Center, we will present lessons learned that can be applied to communications endeavors on all scales, from individual researchers to large organizations. We will explore various channels, messengers, messages, and methods we have used effectively to reach diverse and broad audiences. In thinking about science communications, it is critical to not only understand the audiences we are attempting to reach, but also to meet them in the spaces they frequent. Therefore, we have found value in diversifying communications strategies in order to engage with diverse demographics, using the means most likely to connect with each. Multiple communications channels and strategies reach different age groups, speakers of different languages, and audiences of varying knowledge, experience, age, and interest levels. For example, on social media, Instagram reaches a young demographic and Pinterest is an ideal way to reach educators. Diversity in communications products and channels also addresses varying learning styles and moods, offering opportunities for explanations (e.g, videos

    2017-06-01

    Full Text Available http://dx.doi.org/10.5007/2175-7984.2017v16n35p132 At the gates of the first quarter of the XXI century, nobody doubts the fact that the value chain of the audiovisual industry has suffered important transformations. The digital era presents opportunities for cultural enrichment as well as displays new challenges. After presenting a general portray of the audiovisual industries in the digital era, taking as a point of departure the Spanish case and paying attention to players and logics in tension, this paper will present some notes about the advantages and disadvantages that exist for the diversity of audiovisual production, distribution and consumption online. It is here sustained that the diversity of the audiovisual sector online is not guaranteed because the formula that has made some players successful and powerful is based on walled-garden models to monetize contents (which, besides, add restrictions to their reproduction and circulation by and among consumers. The final objective is to present some ideas about the elements that prevent the strengthening of the diversity of the audiovisual industry in the digital scenario. Barriers to overcome are classified as technological, financial, social, legal and political.

    2009-06-01

    Food and physical activity access and availability in two contrasting cities in Alabama were investigated. An in-outlet, observational, cross-sectional design was utilized to assess the opportunities for healthy food choices and physical activity. Thirty retail food outlets and 29 physical activity outlets were inventoried. None of the convenience stores carried frozen, low-sodium or dark-green, yellow vegetables, low-fat milk or yogurt, low-sodium and low-fat cheese, while none of the supermarkets in Tuskegee stocked low-sodium vegetables. In Tuskegee, the single public recreational area, which offered activities such as basketball, fees ranged from $25 to $35/month. Tuskegee has a shortage of "chain" supermarkets and a dominance of convenience stores which stocked few healthy foods. Overall, there are limited opportunities for healthy food and physical activity choices, which could be a barrier for chronic disease prevention efforts.

  17. Strategic choices for renewable energy investment: Conceptual framework and opportunities for further research

    International Nuclear Information System (INIS)

    Wüstenhagen, Rolf; Menichetti, Emanuela

    2012-01-01

    This paper introduces the special issue on Strategic Choices for Renewable Energy Investment, which is a collection of best papers presented at an international research conference held in St. Gallen (Switzerland) in February 2010. Substantial private investment is needed if public policy objectives to increase the share of renewable energy and prevent dangerous anthropogenic climate change are to be achieved. The aim of this paper, and the entire special issue, is to draw scholarly attention to the processes underlying strategic choices for renewable energy investment, and how they are influenced by energy policy. We disentangle the role of risk-return perceptions, portfolio effects and path dependence in explaining energy investment decisions, and suggest that the heterogeneous universe of investors requires a segmentation of policies. The paper outlines some of the rich opportunities for further research in this emerging area.

    Lenci, E; Menchi, G; Trabocchi, A

    2016-01-21

    Over the last decade, Diversity-Oriented Synthesis (DOS) has become a new paradigm for developing large collections of structurally diverse small molecules as probes to investigate biological pathways, and to provide a larger array of the chemical space. Drug discovery and chemical biology are taking advantage of DOS approaches to exploit highly-diverse and complex molecular platforms, producing advances in both target and ligand discovery. In this view, carbohydrates are attractive building blocks for DOS libraries, due to their stereochemical diversity and high density of polar functional groups, thus offering many possibilities for chemical manipulation and scaffold decoration. This review will discuss research contributions and perspectives on the application of carbohydrate chemistry to explore the accessible chemical space through appendage, stereochemical and scaffold diversity.

  3. Challenges and opportunities of racial diversity in medical education.

    Science.gov (United States)

    Clawson, D K

    1999-05-01

    Racial and cultural diversity in the physician workforce (in orthopaedics this includes women) is an essential if the best healthcare for the American people is to be provided. The percentage of minorities to the white population is increasing yet their representation in medical schools and the practicing community has not risen at that same pace. Affirmative Action efforts continue to be challenged as lowering standards and depriving better qualified students admission to medical schools. Admissions committees and orthopaedic residency directors should recognize that grade point averages and test scores may not be the best predictors of how well a physician or surgeon cares for patients. How far a person has come and what obstacles they have had to overcome, their demonstrated caring and compassion for people, their understanding of diverse cultures and languages may be a far better predictor of the quality of care physicians give to their patients. Affirmative Action should not be looked on as lowering standards, but using all available information in the selection process for medical school and residency training to ensure that the medical profession more closely mirrors the diverse racial and ethnic background of the United States population. How far a person has come and the adversity they have overcome may have far greater impact on making the correct diagnosis and setting out a proper treatment plan that the patient will accept than mastering test taking in the biologic and physical sciences. Obtaining racial and cultural diversity in the medical profession should be a national imperative.

    Although trait choice is crucial to quantify functional diversity appropriately, the quantitative methods for it are rarely compared and discussed. Meanwhile, very little is known about how trait choice affects ecological conclusions drawn from functional diversity measures. We presented the four methods of trait selection as alternatives to the ordination axis-based method, which directly identify a subset of key traits to represent the main variation of all the traits. To evaluate their performance, we compared the closeness of association obtained by different methods between species richness and functional diversity indices (FAD, FD, Q, FDis) in the six ecosystems. The evaluation was also benchmarked against the results obtained by calculating the possible indices using all the trait combinations (the complete search method). We found that the trait selection methods were potential alternatives to axis-based method to gain a mechanistic understanding of functional responses and effects of traits, while these methods as well as the axis-based method possibly use mismatched information to interpret the investigated ecosystem properties. Trait choice profoundly affected the ecological conclusions drawn from functional diversity measures. The complete search method should be used to assess the rationale of different trait choice methods and the quality of the calculated indices.

  7. Media, cultural diversity and globalization: challenges and opportunities.

    Science.gov (United States)

    Zayani, Mohamed

    2011-01-01

    This paper explores the role media play in safeguarding cultural diversity, promoting cultural dialogue, facilitating the exercise of cultural rights,fostering cultural understanding and cultivating intercultural citizenship in the age of globalization. The paper highlights several interconnected leverage points: media content, practices, processes, ownership, education, structures, and policies. It argues that fostering cultural diversity in and through the media can go a long way toward bringing a civic discourse which favors tolerance and facilitates co-existence. It can contribute to the breaking down of cultural barriers, the initiation of cultural dialogues, the empowerment of marginalized groups, and the practice of good governance. At the same time, this paper argues, the celebration of difference does not preclude the valuation of a common cultural core or a common humanity which brings people together in spite of their differences.

  8. Opportunities for synthetic biology in antibiotics: expanding glycopeptide chemical diversity.

    Science.gov (United States)

    Thaker, Maulik N; Wright, Gerard D

    2015-03-20

    Synthetic biology offers a new path for the exploitation and improvement of natural products to address the growing crisis in antibiotic resistance. All antibiotics in clinical use are facing eventual obsolesce as a result of the evolution and dissemination of resistance mechanisms, yet there are few new drug leads forthcoming from the pharmaceutical sector. Natural products of microbial origin have proven over the past 70 years to be the wellspring of antimicrobial drugs. Harnessing synthetic biology thinking and strategies can provide new molecules and expand chemical diversity of known antibiotic scaffolds to provide much needed new drug leads. The glycopeptide antibiotics offer paradigmatic scaffolds suitable for such an approach. We review these strategies here using the glycopeptides as an example and demonstrate how synthetic biology can expand antibiotic chemical diversity to help address the growing resistance crisis.

    2015-04-01

    We begin this talk with a brief description of the gender and ethnic diversity of the physics community. We then discuss several current efforts within Physics Education Research that have the potential to further our understanding of issues surrounding underrepresentation. These efforts include research into (1) the role of community and strategies for developing effective communities; (2) physics identity and self-efficacy; (3) the affordances that students from underrepresented groups bring to physics learning; (4) socioeconomics and its impact on mathematization. One of the challenges to conducting this research is the relatively small proportion of underrepresented minority students in current physics classes, and the small number of women in physics and engineering majors. In collaboration with Stephen Kanim, New Mexico State University.

  10. A culturally diverse staff population: challenges and opportunities for nurses.

    Science.gov (United States)

    Mattson, Susan

    2009-01-01

    The United States is seeing an increase in ethnic and cultural diversity that is reflected (albeit to a smaller extent) in the nursing workforce. There are also more nurses who are foreign-born and educated. These nurses bring elements of their ethnic culture to the healthcare setting, including that of the "healthcare provider" culture of their home country. Often these values conflict with, or at least differ from, many American values seen in the workplace, such as autonomy of patients, an individualistic approach to relationships, peer relationships rather than hierarchical ones, democracy as an ideal norm, optimal health is ideal, and an emphasis on time/schedules and use of technology. A major cultural difference in the work setting has to do with the meaning of "work" itself, which can vary among cultural groups; in addition, some cultures are viewed as more "collective" in nature than the American ones, which are considered "individualistic." In particular, foreign-born and educated nurses from different healthcare systems bring with them values of the political system in which they work, the concept of a socialized system of medicine, language and accent differences, different concepts of nursing duties, and varying psychosocial skills.

    2012-01-01

    We estimated levels of diversity at the major histocompatibility complex (MHC) class II DRß1 gene in 50 breeding pairs of the Magellanic penguin and compared those to estimates from Humboldt and Galapagos penguins. We tested for positive selection and 2 conditions required for the evolution of MHC-based disassortative mating: 1) greater MHC diversity between breeding pairs compared to random mating, and 2) associations between MHC genotype and fitness. Cloning and sequencing of the DRß1 gene showed that Magellanic penguins had higher levels of genetic variation than Galapagos and Humboldt penguins. Sequence analysis revealed 45 alleles with 3.6% average proportion of nucleotide differences, nucleotide diversity of 0.030, and observed heterozygosity of 0.770. A gene phylogeny showed 9 allelic lineages with interspersed DRß1 sequences from Humboldt and Galapagos penguins, indicating ancestral polymorphisms. d (N)/d (S) ratios revealed evidence for positive selection. Analysis of breeding pairs showed no disassortative mating preferences. Significant MHC genotype/fitness associations in females suggest, however, that selection for pathogen resistance plays a more important role than mate choice in maintaining diversity at the MHC in the Magellanic penguin. The differential effect of MHC heterozygosity on fitness between the sexes is likely associated with the relative role of hatching and fledging rates as reliable indicators of overall fitness in males and females.

    2001-04-01

    To examine the gender differences in practice patterns, experiences, and career opportunities for family physicians who practice sports medicine. Descriptive, self-administered questionnaire. Family physicians with Certificate of Added Qualification (CAQ) in sports medicine were surveyed. The survey was sent to all women with a CAQ in Sports Medicine and a random sample of 20% of the men with CAQs in sports medicine. Survey consisted of multiple choice, Likert scale, and opened-ended questions. The data was analyzed with contingency tables, with gender as the dependent variable. Response rate to the survey was 75%, which included 42 females and 102 males. Demographics of our population demonstrated some gender differences. Males were of higher average age (41.1 vs. 38.1), and more likely to be married and have children. Practice types, location, and time spent in sports medicine did not differ with the exception of training room and event coverage. Males were more likely to cover all levels of training room except at the Division I level, where the percent of males and females covering training rooms were equal. Males were also more likely to cover all types of sporting events. Job satisfaction and reasons for choosing current jobs did not show significant gender differences. However, factors affecting career opportunities did vary. Professional relationships with athletic trainers and coaches were perceived to be different by males and females surveyed. Our survey of sports medicine physicians showed some gender differences in practice patterns relative to training room and sporting event coverage. Surprisingly, there were not many differences in the factors that affected job choice and factors affecting job opportunities with the exception of gender itself. However, our study does not conclude how or when gender begins to affect the female sports medicine physician's career opportunities.

    2015-12-01

    Climate literacy and climate education are important topics in current socio-political debate. Despite numerous scientific findings supporting global climate changes and accelerated greenhouse warming, there is a social inertia resisting and slowing the rate at which many of our students understand and absorb these facts. A variety of reasons, including: socio-economic interests, political and ideological biases, misinformation from mass media, inappropriate preparation of science teachers, and lack of numancy have created serious challenges for public awareness of such an important issue. Different agencies and organizations (NASA, NOAA, EPA, AGU, APS, AMS and others) have created training programs for educators, not involved directly in climatology research, in order to learn climate science in a consistent way and then communicate it to the public and students. Different approaches on how to deliver such information to undergraduate students in diverse environments is discussed based on the author's experiences working in different minority-serving institutions across the nation and who have attended AMS Weather and Climate Studies training workshops, MSI-REACH, and the School of Ice. Different parameters are included in the analysis: demographics of students, size of the institutions, geographical locations, target audience, programs students are enrolled in, conceptual units covered, and availability of climate-related courses in the curricula. Additionally, the feasibility of incorporating a laboratory and quantitative analysis is analyzed. As a result of these comparisons it seems that downscaling of climate education experiences do not always work as expected in every institution regardless of the student body demographics. Different geographical areas, student body characteristics and type of institution determine the approach to be adopted as well as the feasibility to introduce different components for weather and climate studies. Some ideas are shared

  16. GOLD (GEO Opportunities for Leadership in Diversity): Building capacity for broadening participation in the Geosciences

    Science.gov (United States)

    Jones, B.; Patino, L. C.; Rom, E. L.; Adams, A.

    2017-12-01

    The geosciences continue to lag other science, technology, engineering, and mathematics (STEM) disciplines in the engagement, recruitment and retention of traditionally underrepresented and underserved groups, requiring more focused and strategic efforts to address this problem. Prior investments made by the National Science Foundation (NSF) related to broadening participation in STEM have identified many effective strategies and model programs for engaging, recruiting, and retaining underrepresented students in the geosciences. These investments also have documented clearly the importance of committed, knowledgeable, and persistent leadership for making local progress in this area. Achieving diversity at larger and systemic scales requires a network of diversity "champions" who can catalyze widespread adoption of these evidence-based best practices and resources. Although many members of the geoscience community are committed to the ideals of broadening participation, the skills and competencies to achieve success must be developed. The NSF GEO Opportunities for Leadership in Diversity (GOLD) program was implemented in 2016, as a funding opportunity utilizing the Ideas Lab mechanism. Ideas Labs are intensive workshops focused on finding innovative solutions to grand challenge problems. The ultimate aim of this Ideas Lab, organized by the NSF Directorate for Geosciences (GEO), was to facilitate the design, pilot implementation, and evaluation of innovative professional development curricula that can unleash the potential of geoscientists with interests in broadening participation to become impactful leaders within the community. The expectation is that mixing geoscientists with experts in broadening participation research, behavioral change, social psychology, institutional change management, leadership development research, and pedagogies for professional development will not only engender fresh thinking and innovative approaches for preparing and empowering

    2010-04-01

    BACKGROUND/CONTEXT: Brown v Board of Education fundamentally changed our nation's schools, yet we know surprisingly little about how and whether they provide equality of educational opportunity. Although substantial evidence suggests that African American and Latino students who attend these schools face fewer learning opportunities than their White counterparts, until now, it has been impossible to examine this using a representative sample because of lack of data. PURPOSE/OBJECTIVE/RESEARCH QUESTION/FOCUS OF STUDY: This study uses newly available data to investigate whether racially diverse high schools offer equality of educational opportunity to students from different racial and ethnic groups. This is examined by measuring the relative representation of minority students in advanced math classes at the beginning of high school and estimating whether and how this opportunity structure limits the level of achievement attained by African American and Latino students by the end of high school. SETTING: This study uses data from the Adolescent Health and Academic Achievement Study (AHAA) and its partner study, the National Longitudinal Study of Adolescent Health (Add Health), a stratified, nationally representative study of students in U.S. high schools first surveyed in 1994-1995. POPULATION/PARTICIPANTS/SUBJECTS: Two samples of racially diverse high schools were used in the analysis: one with African Americans, Whites, and Asians (26 schools with 3,149 students), and the other with Latinos, Whites, and Asians (22 schools with 2,775 students). RESEARCH DESIGN: Quantitative analyses first assess how high schools vary in the extent to which minority students are underrepresented in advanced sophomore math classes. Hierarchical multilevel modeling is then used to estimate whether racial-ethnic differences in representation in advanced math have an impact on African American and Latino students' achievement by the end of high school, relative to the Whites and Asians

    Past innovation research has largely neglected potential effects of corporate governance issues on strategic choices, and thereby on innovation management outcomes. The theory of upper echelon implies that strategic choices result from idiosyncrasies of top management teams (TMT). Building...... show that TMT diversity has a strong impact on the strategic choice of firms to focus on innovation fields. Such focus then drives new product portfolio innovativeness and firm performance. As corporate governance arrangements thus seem relevant in the context of innovation management, we can derive...... on this theory, we hypothesize that TMT diversity enhances firm performance by facilitating an innovation strategy that increases the firm's new product portfolio innovativeness. Our findings support the relevance of considering a corporate governance view for explaining innovation outcomes. Empirically, we can...

    McDowell CHOICES (Coordinated Health Opportunities Involving Communities, Environments, and Schools) Project is a county wide endeavor aimed at increasing opportunities for physical activity (PA) in McDowell County, West Virginia (WV). A comprehensive needs-assessment laid the foundation of the project. During the 6 month needs assessment, multiple sources of data were collected in two Town Hall Meetings (n = 80); a student online PA interest survey (n = 465); a PA and nutrition survey among 5(th) (10-11 years) and 8(th) graders (13-14 years) with questions adapted from the CDC's Youth Risk Behavior Surveillance Survey (n = 442, response rate = 82.2%); six semi-structured school and community focus groups (n = 44); school site visits (n = 11); and BMI screening (n = 550, response rate = 69.7%). One third of children in McDowell County meet the national PA minimum of 60 minutes daily. At least 40% of 5(th) and 8(th) graders engage in electronic screen activity for 3 hours or more every day. The prevalence of obesity in 5(th) graders is higher in McDowell County than the rest of WV (~55% vs. 47% respectively). SWOT analyses of focus group data suggest an overall interest in PA but also highlight a need for increase in structured PA opportunities. Focus group data also suggested that a central communication (e.g. internet-based) platform would be beneficial to advertise and boost participation both in current and future programs. Schools were commonly mentioned as potential facilities for public PA participation throughout the county, both with regards to access and convenience. School site visits suggest that schools need more equipment and resources for before, during, and after school programs. An overwhelming majority of participants in the McDowell CHOICES needs assessment were interested to participate in more PA programs throughout the county as well as to improve opportunities for the provision of such programs. Public schools were widely recognized as the hub

  1. Opportunity, challenges and policy choices for China on the development of shale gas

    2013-01-01

    With the highest shale gas reserves worldwide and huge need for energy, the Chinese government has introduced many incentives to accelerate the development of shale gas, including subsidies and reduction or waiver of the related fees or taxes. However, the challenges posed by a lack of advanced technologies, environmental protection, a shortage of water in quantity and a knowledge of how to develop a good industry–local community relationship are anticipated in the realization of the predicted golden age of the Chinese shale gas industry. Based on the particular situation and available resources in China, and with reference to the experiences in countries with a developed shale gas industry (such as the U.S.A.) and suggestions by the International Energy Agency, recommendations about the choices facing China can be summarized as follows: allowing foreign investors directly to hold exploration and mining rights in shale gas could facilitate the obtainment of advanced technologies; the improvement of the regulatory arrangements related to environmental protection could make developers more responsible; prompting developers to improve their water-use efficiency could help in not worsening the water supply to some extent; and SLO-based mechanism guidance could be helpful in developing a mutual-trust and -benefit relationship between the shale gas industry and the local community. - Highlights: • China faces four major challenges in shale gas development. • Granting foreign investors mining rights is helpful to get advanced technology soon. • Improving environmental regulation could make developers more responsible. • Developers' efficient water-use could help in not worsening water supply. • SLO-based mechanism guidance may improve industry–community relationship

    Employing Rothschild's Motivation-Opportunity-Ability framework, the present study examines the extent to which heterogeneity in barriers regarding the motivation, the perceived opportunity and the perceived ability to choose low-calorie over high-calorie snacks is associated with the proportion of low-calorie snack choices in real life. Furthermore, the study investigates which dominant barrier profiles can be discerned. Data were obtained from a survey about participants' motivation, opportunity and ability to choose low-calorie over high-calorie snacks and an FFQ that measured habitual consumption of snack foods and beverages. Data were analysed using R packages lavaan and NbClust, and IBM SPSS Statistics. A representative sample (n 1318) of the Dutch population based on gender (686 women), age and education level. For both snack foods and beverages, motivation to choose low-calorie over high-calorie snacks was associated strongest with proportions of low-calorie choices. The perceived ability and perceived opportunity were also associated with proportions of low-calorie choices, albeit to a lesser extent. Furthermore, three dominant profiles of barriers were identified: the no-barrier profile, the lack-of-opportunity profile and the lack-of-motivation profile. These profiles differed significantly on proportions of low-calorie snack choices, daily meal consumption and sociodemographic characteristics. Heterogeneity in barriers regarding the motivation, the perceived opportunity and the perceived ability to choose low-calorie over high-calorie snacks is associated with the proportion of low-calorie snack choices in real life. By identifying and appreciating heterogeneity in barriers, the present study provides further incentives for the tailoring of intervention strategies.

    There is attrition of women across professorial ranks in academic pathology. Women are underrepresented as leaders; 15.4% of academic pathology departments are chaired by women, according to the Association of American Medical Colleges (AAMC). To identify areas for targeted interventions that can advance academic and leadership development of women faculty by examining (1) sex differences in career satisfaction in US medical school pathology departments participating in the AAMC's Faculty Forward Engagement Survey, and (2) findings from a survey of the Association of Pathology Chairs (APC). The AAMC Faculty Forward Engagement Survey data are from 14 US medical schools participating in the 2011-2012 survey. Pathologists' response rate was 66% (461 of 697). To investigate sex differences, t tests and χ(2) analyses were used. The APC survey, administered to academic department chairs, had a 55% response rate (104 of 189). According to the Faculty Forward Engagement Survey, women report more time in patient care and less time in research. Women consider formal mentorship, feedback, and career advancement more important than men do and are less satisfied with communication and governance. The APC survey shows that 20% to 40% of nonchair department leaders are women. More than half of chairs report satisfaction with the sex diversity of their departmental leaders. Opportunities exist for department chairs and professional organizations to create targeted interventions to support career satisfaction, recruitment, retention, and career and leadership development for women in academic pathology. Although chairs report satisfaction with diversity within department leadership, responses of women faculty indicate there is work to be done to grow more women leaders.

    Elliott Ronald Dossou-Yovo

    Full Text Available Inland valleys are becoming increasingly important agricultural production areas for rural households in sub-Saharan Africa due to their relative high and secure water availability and soil fertility. In addition, inland valleys are important as water buffer and biodiversity hot spots and they provide local communities with forest, forage, and fishing resources. As different inland-valley ecosystem functions may conflict with agricultural objectives, indiscriminate development should be avoided. This study aims to analyze the diversity of inland valleys in Sierra Leone and to develop guidelines for more precise interventions. Land use, biophysical and socio-economic data were analyzed on 257 inland valleys using spatial and multivariate techniques. Five cluster groups of inland valleys were identified: (i semi-permanently flooded with high soil organic carbon (4.2% and moderate available phosphorus (10.2 ppm, mostly under natural vegetation; (ii semi-permanently flooded with low soil organic carbon (1.5% and very low available phosphorus (3.1 ppm, abandoned by farmers; (iii seasonally flooded with moderate soil organic carbon (3.1% and low available phosphorus (8.3 ppm, used for rainfed rice and off-season vegetables produced without fertilizer application for household consumption and market; (iv well drained with moderate soil organic carbon (3.8% and moderate available phosphorus (10.0 ppm, used for rainfed rice and off-season vegetables produced with fertilizer application for household consumption and market; and (v well drained with moderate soil organic carbon (3.6% and moderate available phosphorus (11 ppm, used for household consumption without fertilizer application. Soil organic carbon, available phosphorus, hydrological regime, physical accessibility and market opportunity were the major factors affecting agricultural intensification of inland valleys. Opening up the areas in which inland valleys occur through improved roads and

    Full Text Available This paper critically reviews various learning preferences and human intelligence theories and models with a particular focus on the implications for online learning. It highlights a few key models, Gardner’s multiple intelligences, Fleming and Mills’ VARK model, Honey and Mumford’s Learning Styles, and Kolb’s Experiential Learning Model, and attempts to link them to trends and opportunities in online learning with emerging technologies. By intersecting such models with online technologies, it offers instructors and instructional designers across educational sectors and situations new ways to think about addressing diverse learner needs, backgrounds, and expectations. Learning technologies are important for effective teaching, as are theories and models and theories of learning. We argue that more immense power can be derived from connections between the theories, models and learning technologies.

    Seed dispersal is typically performed by a diverse array of species assemblages with different behavioral and morphological traits which determine dispersal quality (DQ, defined as the probability of recruitment of a dispersed seed). Fate of ecosystems to ongoing environmental changes is critically dependent on dispersal and mainly on DQ in novel scenarios. We assess here the DQ, thus the multiplicative effect of germination and survival probability to the first 3 years of life, for seeds dispersed by several bird species (Turdus spp.) and carnivores (Vulpes vulpes, Martes foina) in mature woodland remnants of Spanish juniper (Juniperus thurifera) and old fields which are being colonized by this species. Results showed that DQ was similar in mature woodlands and old fields. Germination rate for seeds dispersed by carnivores (11.5%) and thrushes (9.12%) was similar, however, interacted with microhabitat suitability. Seeds dispersed by carnivores reach the maximum germination rate on shrubs (16%), whereas seeds dispersed by thrushes did on female juniper canopies (15.5) indicating that each group of dispersers performed a directed dispersal. This directional effect was diluted when survival probability was considered: thrushes selected smaller seeds which had higher mortality in the seedling stage (70%) in relation to seedlings dispersed by carnivores (40%). Overall, thrushes resulted low-quality dispersers which provided a probability or recruitment of 2.5%, while a seed dispersed by carnivores had a probability of recruitment of 6.5%. Our findings show that generalist dispersers (i.e., carnivores) can provide a higher probability of recruitment than specialized dispersers (i.e., Turdus spp.). However, generalist species are usually opportunistic dispersers as their role as seed dispersers is dependent on the availability of trophic resources and species feeding preferences. As a result, J. thurifera dispersal community is composed by two functional groups of

    Prune belly syndrome has been identified as a clinical triad of abdominal muscle deficiency, bilateral cryptorchidism, and urologic abnormalities. We present the case of a discordant monozygotic twin with prune belly syndrome and voiding dysfunction that was relieved by long-term urinary catheterization by way of the urachus. To the best of our knowledge, this alternative method has not been previously reported. We suggest that for newborn infants with long-term voiding dysfunction, if the urachus retains patency, urinary catheterization through the urachus could be a choice for urine drainage instead of cystostomy, providing a better cosmetic appearance and quality of life.

    Communities, facing tight budgets, volatile markets, and the recycling backlash are turning their attention to making their programs more efficient and effective. Unfortunately, communities have very little quantitative information available to help them improve their programs. This is despite the fact that the majority of recycling programs have been running for over 6 years. Further, the author found that there are many thousands of curbside and dropoff recycling programs across the nation, as well as thousands of yard waste and variable rate programs. Still, with all these years of operating experience across the nation, at conferences, when planners ask about the likely impacts of possible program improvements, the answers usually begin, ``well, the City of [fill in the blank] made that change and found...``. Answers like this are seldom transferable to other communities. Similarly, most published information also relies on one or a few (less than ten) case studies, and published case studies usually describe programs that are outstanding in some way, making the information even less transferable. This type of information is wholly inadequate to derive information that is transferable to any other community. Can one really expect information from the City of San Jose, California, to transfer directly to the Village of Hartland, Wisconsin? That is the level of information that has been available thus far to planners. This study uses specially collected data from over 500 communities across North America as the basis for a statistical analysis of those programmatic and socio-demographic factors that contribute most to higher levels of recycling diversion. The work is unique in that it provides the first reliable quantitative information for use by community program planners in analyzing impacts of alternative programs and their cost-effectiveness to design sustainable, appropriate programs to improve diversion.

  13. Challenges and opportunities in estimating viral genetic diversity from next-generation sequencing data

    Full Text Available Many viruses, including the clinically relevant RNA viruses HIV and HCV, exist in large populations and display high genetic heterogeneity within and between infected hosts. Assessing intra-patient viral genetic diversity is essential for understanding the evolutionary dynamics of viruses, for designing effective vaccines, and for the success of antiviral therapy. Next-generation sequencing technologies allow the rapid and cost-effective acquisition of thousands to millions of short DNA sequences from a single sample. However, this approach entails several challenges in experimental design and computational data analysis. Here, we review the entire process of inferring viral diversity from sample collection to computing measures of genetic diversity. We discuss sample preparation, including reverse transcription and amplification, and the effect of experimental conditions on diversity estimates due to in vitro base substitutions, insertions, deletions, and recombination. The use of different next-generation sequencing platforms and their sequencing error profiles are compared in the context of various applications of diversity estimation, ranging from the detection of single nucleotide variants to the reconstruction of whole-genome haplotypes. We describe the statistical and computational challenges arising from these technical artifacts, and we review existing approaches, including available software, for their solution. Finally, we discuss open problems, and highlight successful biomedical applications and potential future clinical use of next-generation sequencing to estimate viral diversity.

  14. Teaching science in culturally diverse classrooms: The relevance of multicultural coursework on novice teachers' instructional choice

    Science.gov (United States)

    Cunha, Thais B. P. da

    Science education reform in the United States has been slow to reduce the troubling science achievement gap between students from mainstream and non-mainstream backgrounds. Recent data suggest the gap persists in spite of improved attention to the multicultural education of teachers, and in spite of recent, more culturally inclusive and responsive curricular materials and instructional recommendations. In this study, I examine the cases of two European American male novice science teachers in middle schools with highly diverse populations, exploring their perceptions of the necessity of adapting their instructional approaches and the science curricula in order to meet the needs of their predominantly Native American, Mexican American, and African American students. Two theoretical frameworks inform this study, Rodriguez's (2005) sociotransformative constructivism, and Freire's critical pedagogy. I apply a qualitative case study method, to better understand and analyze the classroom setting and power relations of the context. Data consist of semi-structured interviews with each teacher, classroom observation and other field notes, the science curricular and instructional materials, and teachers' lesson plans. Each teacher acknowledged the ethnicities of students positively and noticed distinctive ethnocultural features (e.g., quinceaneras, Mexican Americans). Yet, their teaching approaches were primarily teacher-centric and monocultural. Each followed the book, usually lecturing, and striving dutifully to "cover" the topics. They did not solicit students' knowledge or engage them in dialog to explore their thinking. Even when the curriculum guide detailed relevant science knowledge students of some cultural groups might have, both teachers declined to use it. These well-meaning teachers did not fully perceive that students whose culture was different from their own might have different and relevant knowledge, experiences, or histories which were resources for

    Committed to its mission of conducting and supporting research that addresses the health needs of all sectors of the nation's population, the Division of Lung Diseases, National Heart, Lung, and Blood Institute of the National Institutes of Health (NHLBI/NIH) seeks to identify issues that impact the training and retention of underrepresented individuals in the biomedical research workforce. Early-stage investigators who received grant support through the NIH Research Supplements to Promote Diversity in Health Related Research Program were invited to a workshop held in Bethesda, Maryland in June, 2015, in order to (1) assess the effectiveness of the current NHLBI diversity program, (2) improve its strategies towards achieving its goal, and (3) provide guidance to assist the transition of diversity supplement recipients to independent NIH grant support. Workshop participants participated in five independent focus groups to discuss specific topics affecting underrepresented individuals in the biomedical sciences: (1) Socioeconomic barriers to success for diverse research scientists; (2) role of the academic research community in promoting diversity; (3) life beyond a research project grant: non-primary investigator career paths in research; (4) facilitating career development of diverse independent research scientists through NHLBI diversity programs; and (5) effectiveness of current NHLBI programs for promoting diversity of the biomedical workforce. Several key issues experienced by young, underrepresented biomedical scientists were identified, and solutions were proposed to improve on training and career development for diverse students, from the high school to postdoctoral trainee level, and address limitations of currently available diversity programs. Although some of the challenges mentioned, such as cost of living, limited parental leave, and insecure extramural funding, are also likely faced by nonminority scientists, these issues are magnified among diversity

    Patients with pancreatic ductal adenocarcinoma (PDA) have a poor prognosis despite new treatments; approximately 7% survive for 5 years. Although there have been advances in systemic, primarily cytotoxic, therapies, it has been a challenge to treat patients with PDA using targeted therapies. Sequence analyses have provided a wealth of information about the genetic features of PDA and have identified potential therapeutic targets. Preclinical and early-phase clinical studies have found specific pathways could be rationally targeted; it might also be possible to take advantage of the genetic diversity of PDAs to develop therapeutic agents. The genetic diversity and instability of PDA cells have long been thought of as obstacles to treatment, but are now considered exploitable features. We review the latest findings in pancreatic cancer genetics and the promise of targeted approaches in PDA therapy. Copyright © 2016 AGA Institute. Published by Elsevier Inc. All rights reserved.

    2013-12-01

    The Opportunities for Enhancing Diversity in the Geosciences (OEDG) program - established in 2002 by the National Science Foundation's Directorate for Geosciences (GEO) - has been a mainstay in GEO's efforts to broaden participation of traditionally underrepresented minorities in the geosciences. The primary goal of the OEDG program has been to engage a diverse population of students in learning about - and pursuing advanced degrees and careers in - the geosciences. Raising public awareness of the importance and relevance of the geosciences among diverse audiences has been a secondary goal. During the past decade, the OEDG program has supported a variety of planning grants, proof-of-concept projects, and larger full-scale implementation efforts across the U.S. These projects have contributed a rich array of culturally-tailored resources for learning about geoscience career pathways and opportunities to participate in geoscience research experiences. OEDG has also developed networking and mentoring programs tailored for diverse student audiences, as well as the educators who work with them, and has helped to build capacity in the geosciences at minority-serving institutions. Perhaps the most important legacy of the OEDG program has been the establishment of an enthusiastic and effective community of educators, administrators, students and organizations dedicated to increasing diversity in the geosciences. Evaluation data collected for individual OEDG projects has helped to improve the impact of specific projects and increase our understanding of which approaches are more successful in achieving OEDG program goals. In addition, GEO has supported a decade-long, program-wide evaluation of the OEDG portfolio through a contract to the American Institutes for Research (AIR). Synthesis of results from both the project- and program-level evaluation activities has identified evidence-based 'best practices' that are essential for achieving success in broadening participation

  2. Can MHC-assortative partner choice promote offspring diversity? A new combination of MHC-dependent behaviours among sexes in a highly successful invasive mammal.

    Santos, Pablo S C; Michler, Frank-Uwe; Sommer, Simone

    2017-04-01

    Sexual selection involving genetically disassortative mate choice is one of several evolutionary processes that can maintain or enhance population genetic variability. Examples of reproductive systems in which choosers (generally females) select mates depending on their major histocompatibility complex (MHC) genes have been reported for several vertebrate species. Notably, the role of MHC-dependent choice not in mating contexts, but in other kinds of social interactions such as in the establishment of complex social systems, has not yet drawn significant scientific interest and is virtually absent from the literature. We have investigated male and female MHC-dependent choice in an invasive population of North American raccoons (Procyon lotor) in Germany. Both male and female raccoons rely on olfaction for individual recognition. Males have an unusually complex social system in which older individuals choose unrelated younger ones to form stable male coalitions that defend territories and a monopoly over females. We have confirmed that females perform MHC-disassortative mate choice and that this behaviour fosters genetic diversity of offspring. We have also observed that males build coalitions by choosing male partners depending on their MHC, but in an assortative manner. This is the first observation of antagonistic MHC-dependent behaviours among sexes. We show that this is the only combination of MHC-dependent partner choice that leads to outbreeding. In the case of introduced raccoons, such behaviours can act together to promote the invasive potential of the species by increasing its adaptive genetic divergence. © 2017 John Wiley & Sons Ltd.

  3. PCR and Omics Based Techniques to Study the Diversity, Ecology and Biology of Anaerobic Fungi: Insights, Challenges and Opportunities

    Full Text Available Anaerobic fungi (phylum Neocallimastigomycota are common inhabitants of the digestive tract of mammalian herbivores, and in the rumen, can account for up to 20% of the microbial biomass. Anaerobic fungi play a primary role in the degradation of lignocellulosic plant material. They also have a syntrophic interaction with methanogenic archaea, which increases their fiber degradation activity. To date, nine anaerobic fungal genera have been described, with further novel taxonomic groupings known to exist based on culture-independent molecular surveys. However, the true extent of their diversity may be even more extensively underestimated as anaerobic fungi continue being discovered in yet unexplored gut and non-gut environments. Additionally many studies are now known to have used primers that provide incomplete coverage of the Neocallimastigomycota. For ecological studies the internal transcribed spacer 1 region (ITS1 has been the taxonomic marker of choice, but due to various limitations the large subunit rRNA (LSU is now being increasingly used. How the continued expansion of our knowledge regarding anaerobic fungal diversity will impact on our understanding of their biology and ecological role remains unclear; particularly as it is becoming apparent that anaerobic fungi display niche differentiation. As a consequence, there is a need to move beyond the broad generalization of anaerobic fungi as fiber-degraders, and explore the fundamental differences that underpin their ability to exist in distinct ecological niches. Application of genomics, transcriptomics, proteomics and metabolomics to their study in pure/mixed cultures and environmental samples will be invaluable in this process. To date the genomes and transcriptomes of several characterized anaerobic fungal isolates have been successfully generated.

    The sustainability of biofuel expansion is strongly dependent on the environmental footprint of feedstock production, including both direct impacts within feedstock-producing areas and potential leakage effects due to disruption of existing food, feed, or fiber production. Assessing and minimizing these impacts requires novel methods compared to traditional supply chain lifecycle assessment. When properly validated and applied at appropriate spatial resolutions, biogeochemical process models are useful for simulating how the productivity and soil greenhouse gas fluxes of cultivating both conventional crops and advanced feedstock crops respond across gradients of land quality and management intensity. In this work we use the DayCent model to assess the biogeochemical impacts of agricultural residue collection, establishment of perennial grasses on marginal cropland or conservation easements, and intensification of existing cropping at high spatial resolution across several real-world case study landscapes in diverse US agricultural regions. We integrate the resulting estimates of productivity, soil carbon changes, and nitrous oxide emissions with crop production budgets and lifecycle inventories, and perform a basic optimization to generate landscape cost/GHG frontiers and determine the most practical opportunities for low-impact feedstock provisioning. The optimization is constrained to assess the minimum combined impacts of residue collection, land use change, and intensification of existing agriculture necessary for the landscape to supply a commercial-scale biorefinery while maintaining exiting food, feed, and fiber production levels. These techniques can be used to assess how different feedstock provisioning strategies perform on both economic and environmental criteria, and sensitivity of performance to environmental and land use factors. The included figure shows an example feedstock cost-GHG mitigation tradeoff frontier for a commercial-scale cellulosic

    Full Text Available In the context of understanding and predicting the effects of human-induced environmental change (EC on biodiversity (BD, and the consequences of BD change for ecosystem functioning (EF, microbial ecologists face the challenge of linking individual level variability in functional traits to larger scale ecosystem processes. Since lower level BD at genetic, individual, and population levels largely determines the functionality and resilience of natural populations and communities, individual level measures promise to link EC-induced physiological, ecological and evolutionary responses to EF. Intraspecific trait differences, while representing among the least understood aspects of natural microbial communities, have recently become easier to measure due to new technology. For example, recent advance in scanning flow-cytometry (SCF, automation of phytoplankton sampling and integration with environmental sensors allow to measure morphological and physiological traits of individual algae with high spatial and temporal resolution. Here we present emerging features of automated SFC data from natural phytoplankton communities and the opportunities that they provide for understanding the functioning of complex aquatic microbial communities. We highlight some current limitations and future needs, particularly focusing on the large amount of individual level data that, for the purpose of understanding the EC-BD-EF link, need to be translated into meaningful BD indices. We review the available functional diversity indices that, despite having been designed for mean trait values at the species level, can be adapted to individual-based trait data and provide links to ecological theory. We conclude that, considering some computational, mathematical and ecological issues, a set of multi-dimensional indices that address richness, evenness and divergence in overall community trait space represent the most promising BD metrics to study EC-BD-EF using individual

    As children approach early adolescence, the risk of peer victimization often increases. Many children experience some form of peer victimization during this time, but children who experience chronic victimization may be particularly vulnerable to adjustment difficulties. Thus, identifying risk and protective factors associated with chronic victimization continues to be an important area of research. This study examined the effect of change in the victimization of friends on change in children's own victimization, taking into account the ethnic group representation of children in their classes. Over 3000 6th grade students (52 % female; M = 11.33 years) were drawn from 19 middle schools varying in ethnic composition. Friendships were distinguished by type-reciprocal, desired, and undesired-and a novel methodology for measuring ethnic group representation at the individual level was employed. Multilevel modeling indicated that change in friends' victimization from fall to spring of 6th grade had a differential impact on children's own victimization by friendship type and that the benefits and consequences of change in friends' victimization were especially pronounced for children in the numerical ethnic majority. The findings underscore the role of friendship choices in peer victimization, even if those choices are not reciprocated, and highlight the unique social risks associated with being in the numerical ethnic majority.

    The liberation model hypothesizes that school choice liberates students from underperforming schools by giving them the opportunity to seek academically superior schooling options outside of their neighborhoods. Subsequently, school choice is hypothesized to diminish stratification in schools. Data from one urban school district is analyzed to test these hypotheses. We specifically examine which factors influence the propensity for parents to participate in choice, and how school choice changes the racial/ethnic and economic composition of schools. We further examine how school choice influences similar changes within distinct sociogeographic areas within the district. We find that families who are zoned to more racially/ethnically and economically diverse schools in sociogeographically diverse areas are more likely to participate in school choice. We also find that intra-district choice is associated with a slight increase in social stratification throughout the district, with more substantial stratification occurring in the most demographically diverse areas and schools.

    The panel discussing market opportunities for municipal electric companies was moderated by Markham Mayor Don Cousens. He expressed himself in favour of deregulation and was optimistic about the benefits it will bring to municipal electric utilities and their customers. Barry Chuddy, General Manager of Business Development for TransAlta Energy discussed the advantages of recent cogeneration and district energy for municipal utilities in Ontario and Quebec, and expressed his support for incentive-based regulation based on a level playing field, competitive generation, and a reasonable charge for stranded assets. Toronto City Councillor Dan Leckie described cogeneration and district energy as a tremendous opportunity to reduce the cost of doing business in the city core through local job creation and by keeping money in the local economy. Karl Wahl, General Manager of Hydro Mississauga expressed optimism that the government will move expeditiously toward competition, choice and lower-cost supply. David McGarry, President of Elecsar Engineering of Sarnia spoke about the significant job creating potential that deregulation will bring to the electrical industry.

    2017-11-01

    Full Text Available This paper analyzes the contours of religious and nonreligious diversity in the Canadian public sphere. The ever-changing (nonreligious landscape offers an opportunity to consider the flow of ideas from this new diversity to responses and choices at the individual, group, and state levels to inclusion and exclusion. The paper first begins with a descriptive approach to religious diversity, identifying the normatively-charged nature inherent to measures of religion. It then turns to the notion of choices, considering the somewhat uniquely Canadian contributions of multiculturalism, reasonable accommodation, and the recent complication of nonreligion as a category of religious identity. The paper then considers three case studies which reveal the tensions embedded in the new diversity and responses to it in Canada, including (1 the Saint-Sacrement Hospital crucifix incident; (2 Zunera Ishaq’s challenge to the citizenship ceremony niqab ban; and (3 school controversies in Ontario’s Peel Region.

  4. Navigating the market of welfare services: The choice of upper secondary school in Sweden

    Directory of Open Access Journals (Sweden)

    Torbjörn Hjort

    2014-06-01

    Full Text Available Due to increased market orientation and deregulation, welfare services in Sweden have taken on the form of market-based services. The body of research on deregulation and privatization is quite substantial regarding the implications of this kind of development. However, studies of the actual process of how choices are made are less common. This article discusses the implications of greater freedom of choice for Swedish citizens in diverse socioeconomic situations, focusing on factors that limit opportunities for choice. Deregulation and the increasing number of alternatives affect the relationship between the citizen and the welfare state in several ways. The Swedish school system is used here as an example of an empirical field. The analytical focus of the article consists of two different kinds of restrictions on choice: structure-based and agency-based. One conclusion is that both affluent and underprivileged citizens have limited choices. Another conclusion is that social citizenship, when freedom of choice is stimulated, can reproduce and even increase social and ethnic segregation. An additional potential consequence is that, when we consider social rights in their tangible form, the development of greater freedom of choice is focused increasingly on the consumer’s range of choices and less on the quality of the service offered.

    We investigate the feasibility of inferring the choices people would make (if given the opportunity) based on their neural responses to the pertinent prospects when they are not engaged in actual decision making. The ability to make such inferences is of potential value when choice data are unavailable, or limited in ways that render standard methods of estimating choice mappings problematic. We formulate prediction models relating choices to “non-choice” neural responses and use them to predict out-of-sample choices for new items and for new groups of individuals. The predictions are sufficiently accurate to establish the feasibility of our approach. PMID:25729468

    AC, the axiom of choice, because of its non-constructive character, is the most controversial mathematical axiom, shunned by some, used indiscriminately by others. This treatise shows paradigmatically that: Disasters happen without AC: Many fundamental mathematical results fail (being equivalent in ZF to AC or to some weak form of AC). Disasters happen with AC: Many undesirable mathematical monsters are being created (e.g., non measurable sets and undeterminate games). Some beautiful mathematical theorems hold only if AC is replaced by some alternative axiom, contradicting AC (e.g., by AD, the axiom of determinateness). Illuminating examples are drawn from diverse areas of mathematics, particularly from general topology, but also from algebra, order theory, elementary analysis, measure theory, game theory, and graph theory.

    Full Text Available The influences of globalisation and multilingualism have caused linguistic diversity and emergence of interesting and unique sociolinguistic phenomena, for instance, language contact in intercultural communication. As the study of intercultural communication has yet to be studied at large, this research takes the opportunity to embark on a descriptive study of code choice within intercultural communication, relating to the ethnic minorities in Brunei Darussalam. This investigation aims to identify these ethnics’ preferable code choice within intercultural communication, and their needs and motivations practising those codes in a shared multilingual setting. Involving empirical investigation, this study was conducted on 60 native Brunei ethnics in Mukim Ukong, Tutong District. Research found that study involving multilingual settings and intercultural communications are rather relatively complex sociolinguistic phenomena, where speakers would employ different dialects or languages at an episode of communication, but still mutually understood by each other. To some extent, some speakers also accommodate their speech styles or languages to ease communication process between parties. The hegemony of globalisation, local vernacular, speakers’ background and setting are among others influenced the selection of their everyday code choice.

We hypothesise that the number of times that respondents shift their visual...... attention between the alternatives in a choice set reflects their stated choice certainty. Based on one of the largest samples of eye tracking data in a DCE to date, we find evidence in favor of our hypothesis. We also link eye tracking observations to model-based choice certainty through parameterization...... of the scale function in a random parameters logit model. We find that choices characterized by more frequent gaze shifting do indeed exhibit a higher degree of error variance, however, this effects is insignificant once response time is controlled for.

    2014-01-01

    This work discusses the significant changes in computing landscape related to the progression of Moore's Law, and the implications on scientific computing. Particular attention is devoted to the High Energy Physics domain (HEP), which has always made good use of threading, but levels of parallelism closer to the hardware were often left underutilized. Findings of the CERN openlab Platform Competence Center are reported in the context of expanding p erformance dimensions , and especially the resurgence of vectors. These suggest that data oriented designs are feasible in HEP and have considerable potential for performance improvements on multiple levels, but will rarely trump algorithmic enhancements. Finally, an analysis of upcoming hardware and software technologies identifies heterogeneity as a major challenge for software, which will require more emphasis on scalable, efficient design

Although the recent legislative measures quite openly establish a link between...... informed choice and the rather abstract societal norm of “what is good for the consumer,” this does not justify the conclusion that food information legislation has become overly meddlesome in relation to EU consumers and their choice of food.

    We introduce and study the problem of manipulation of choice behavior. In a class of two-stage models of decision making, with the agent's choices determined by three "psychological variables," we imagine that a subset of these variables can be selected by a "manipulator." To what extent does this confer control of the agent's behavior? Within the specified framework, which overlaps with two existing models of choice under cognitive constraints, we provide a complete answer to this question.

    Introduction Information regarding career choices of medical students is important to plan human resources for health, design need-based educational programs, and ensure equitable and quality health care services in a country. Aim The aim of the study is to identify career choices, nature of career, intended practice locations, and reasons for career choices of Bangladesh medical students. Method First-, third-, and fifth-year students of Bangladesh Medical College and Uttara Adhunik Medical College completed a self-report questionnaire on career choices, nature of career, intended practice locations, and reasons for career choices. The students were requested to choose three long-term choices from the given specialties. Results A total of 132 students responded (46 males and 86 females) and response rate was 75%. The popular choices (first choice) among males and females were medical specialty, surgical specialty, obstetrics and gynecology, and general practice. For first, second, and third choices altogether, male students chose surgical specialties and female students preferred medical specialties. The leading reasons for selecting a specialty were personal interest and wide job opportunity. More than 67% of respondents wanted to join private services and about 90% chose major cities as practice locations. About 43% of respondents expressed willingness to practice medicine in Bangladesh, whereas 51% of total respondents wanted to practice abroad. Discussion Majority of students intended to specialize in established clinical specialties and subsequently practice in major cities, and more than half wanted to immigrate to other countries. Basic medical subjects and service-oriented (lifestyle-related) and preventive/social medical specialties were found to be less attractive. If this pattern continues, Bangladesh will suffer a chronic shortage of health personnel in certain specialties and in rural areas. Conclusions Reorientation of health care and medical

    Full Text Available Standards, benchmarks, define modern life, but do they diminish the importance of diversity for progress? Arguably not, for diversity, or variety, is the essence of economic life in the sense of underlying choice; economic calculation gives numerical substance to how people make choices in their daily endeavours, either as consumers or entrepreneurs. How does variety/diversity takes shape in the realm of institutions and policy making? Is the range of choices open-ended? The last couple of decades has revealed an overwhelming offensive of the neo-liberal paradigm in terms of defining “best practices”. Even language was shaped accordingly with market reforms being seen in a quasi-single theoretical and policy framework. Are we heading towards increasing uniformity with regard to institutional and policy set ups, worldwide? An affirmative answer would underline the successful market based transformation of a series of command economies. Some convergence between institutional patterns in the USA and the EU economies might be alluded to in the same vein A supportive argument for this line of reasoning would be that what matters for individual achievement, in the end, are equal opportunities. But this argument can be turned around when debating the merits of various institutional set ups in terms of creating fair chances for people. A sceptical answer would highlight the mounting challenges which confront societies, whether rich and poor, and the international community in general—in spite of the high hopes of not long ago. The demise of the “New Economy”, the series of corporate scandals in wealthy economies and the subsequent recourse to new regulatory legislation, recurrent financial and currency crises throughout the world, the controversies surrounding the activity of IFIs, should compel “ideologues”, of all sorts, to be more humble in their prescriptions. This essay argues that there is substantial scope for institutional and

    Respondents in Stated Preference studies may be uncertain about their preferences for the good presented to them. Inspired by Wang (J Environ Econ Manag 32:219–232, 1997) we hypothesize that respondents’ stated certainty in choice increases with the utility difference between the alternative chosen...... and the best alternative to that. We test this hypothesis using data from two independent Choice Experiments both focusing on nature values. In modelling respondents’ self-reported certainty in choice, we find evidence that the stated level of certainty increases significantly as utility difference in choice...... sets increases. In addition, stated certainty increases with income. Furthermore, there is some evidence that male respondents are inherently more certain in their choices than females, and a learning effect may increase stated certainty. We find evidence of this in the first study where the good...

    Stevens, Jeffrey R; Mühlhoff, Nelly

    2012-02-01

    Different species vary in their ability to wait for delayed rewards in intertemporal choice tasks. Models of rate maximization account for part of this variation, but other factors such as social structure and feeding ecology seem to underly some species differences. Though studies have evaluated intertemporal choice in several primate species, including Old World monkeys, New World monkeys, and apes, prosimians have not been tested. This study investigated intertemporal choices in three species of lemur (black-and-white ruffed lemurs, Varecia variegata, red ruffed lemurs, Varecia rubra, and black lemurs, Eulemur macaco) to assess how they compare to other primate species and whether their choices are consistent with rate maximization. We offered lemurs a choice between two food items available immediately and six food items available after a delay. We found that by adjusting the delay to the larger reward, the lemurs were indifferent between the two options at a mean delay of 17 s, ranging from 9 to 25 s. These data are comparable to data collected from common marmosets (Callithrix jacchus). The lemur data were not consistent with models of rate maximization. The addition of lemurs to the list of species tested in these tasks will help uncover the role of life history and socio-ecological factors influencing intertemporal choices.

  3. Rewarding healthy food choices in SNAP: behavioral economic applications.

    Science.gov (United States)

    Richards, Michael R; Sindelar, Jody L

    2013-06-01

    American obesity rates continue to escalate, but an effective policy response remains elusive. Specific changes to the Supplemental Nutrition Assistance Program (SNAP) have been proposed as one way to improve nutrition and combat obesity among lower-income populations. While current SNAP proposals hold promise, some important challenges still remain. We discuss the four most common recommendations for changes to SNAP and their benefits and limitations. We then propose three new delivery options for SNAP that take advantage of behavioral economic insights and encourage the selection of healthy foods. Although the existing proposals could help SNAP recipients, they often do not address some important behavioral impediments to buying healthy foods. We believe that behavioral economics can be used to design alternative policies with several advantages, although we recognize and discuss some of their limitations. The first proposal rewards healthy purchases with more SNAP funds and provides an additional incentive to maintain healthier shopping patterns. The second proposal uses the opportunity to win prizes to reward healthy food choices, and the prizes further support healthier habits. The final proposal simplifies healthy food purchases by allowing individuals to commit their SNAP benefits to more nutritious selections in advance. Reforming the delivery structure of SNAP's benefits could help improve nutrition, weight, and overall health of lower-income individuals. We advocate for more and diverse SNAP proposals, which should be tested and, possibly, combined. Their implementation, however, would require political will, administrative capacity, and funding. © 2013 Milbank Memorial Fund.

    The report discusses the perspectives on the evolving U.S. electricity future, the renewable electric technology portfolio, the regional outlook, and the opportunities to move forward. Renewables are at a critical juncture as the domestic electricity marketplace moves toward an era of increased choice and greater diversity. The cost and performance of these technologies have improved dramatically over the past decade, yet their market penetration has stalled as the power industry grapples with the implications of the emerging competitive marketplace. Renewable energy technologies already contribute to the global energy mix and are ready to make an even greater contribution in the future. However, the renewables industry faces critical market uncertainties, both domestically and internationally, as policy commitments to renewables at both the federal and state levels are being reshaped to match the emerging competitive marketplace. The energy decisions that we make, or fail to make, today will have long-lasting implications. We can act now to ensure that renewable energy will play a major role in meeting the challenges of the evolving energy future. We have the power to choose.

    2017-08-01

    Choices made by cats between different types of environmental enrichment may help shelters to prioritize how to most effectively enrich cat housing, especially when limited by space or funds. This study investigates the environmental enrichment use of cats in a choice test. Twenty-six shelter cats were kept singularly in choice chambers for 10days. Each chamber had a central area and four centrally-linked compartments containing different types of environmental enrichment: 1) an empty control, 2) a prey-simulating toy, 3) a perching opportunity, and 4) a hiding opportunity. Cat movement between compartments was quantitatively recorded using a data-logger. Enriched compartments were visited significantly more frequently during the light period than during the dark period. Cats spent a significantly greater percentage of time in the hiding compartment (median=55%, IQR=46) than in the toy compartment (median=2%, IQR=9), or in the empty control compartment (median=4%, IQR=4). These results provide additional evidence to support the value of a hiding box to cats housed in a novel environment, in that they choose hiding relative to other types of environmental enrichment.

This reexamination of opportunity cost addresses this question, and shows that opportunity cost is an ambiguous concept because "two" definitions are in widespread use. One of the definitions is indeed simple, fruitful, and one that…

  12. Angelina′s choice

    Full Text Available This is an opinion piece on how a celebrity′s personal choice to undergo prophylactic mastectomy on discovery of an aberrant gene, when publicly promoted, carries in itself the power to influence and impact healthcare trends and decisions. When celebrities advocate causes that are universally and uniformly acceptable and indisputable as the best in the realm of healthcare and cure (e.g. no smoking, it creates well-being and awareness in society at large. But those which are personal choices made out of a repertoire of other available and effective options may, because of celebrity preference, don the mantle of a norm. They thus run the danger of being blindly replicated by others without proper awareness and knowledge of the true potential of disease, risk factors, and other existing remedial or risk-reducing measures. Society should thus be encouraged to question, debate, and understand the validity, authenticity, and reason of the choices, especially those with a medical basis. This tempering of information with intelligence and rationale and making informed choices based on facts will serve humanity as a whole.

  20. How Choice Changes the Education System: A Michigan Case Study

    Science.gov (United States)

    Plank, David; Sykes, Gary

    1999-11-01

    In countries around the world policy makers propose that parents should exercise more control over the choice of schools that their children attend. This paper considers the ways in which the introduction of new opportunities for school choice changes the education system. It argues that choice affects the education system as a whole by introducing new actors into the system, by changing the terms of relationships among existing actors, and by creating new pressures within the system that require new responses. The nature, magnitude, and consequences of these effects cannot be predicted in advance, as they depend on a number of factors including the social and economic context. The empirical basis for this paper derives from a case study of the implementation of choice policies in the state of Michigan in the US, but the conceptual issues raised have important implications for the study of school choice wherever such policies are adopted.

    Kuhn’s famous thesis that there is ‘no unique algorithm’ for choosing between rival scientific theories is analysed using the machinery of social choice theory. It is shown that the problem of theory choice as posed by Kuhn is formally identical to a standard social choice problem. This suggests that analogues of well-known results from the social choice literature, such as Arrow’s impossibility theorem, may apply to theory choice. If an analogue of Arrow’s theorem does hold for theory choice...

    The recent invention of super-resolution optical microscopy enables the visualization of fine features in biological samples with unprecedented clarity. It creates numerous opportunities in biology because vast amount of previously obscured subcellular processes now can be directly observed. Rapid development in this field in the past two years offers many imaging modalities that address different needs but they also complicates the choice of the 'perfect' method for answering a specific question. Here I will briefly describe the principles of super-resolution optical microscopy techniques and then focus on comparing their characteristics in various aspects of practical applications.

    Analysis with the ParaChoice model addresses three barriers from the VTO Multi-Year Program Plan: availability of alternative fuels and electric charging station infrastructure, availability of AFVs and electric drive vehicles, and consumer reluctance to purchase new technologies. In this fiscal year, we first examined the relationship between the availability of alternative fuels and station infrastructure. Specifically, we studied how electric vehicle charging infrastructure affects the ability of EVs to compete with vehicles that rely on mature, conventional petroleum-based fuels. Second, we studied how the availability of less costly AFVs promotes their representation in the LDV fleet. Third, we used ParaChoice trade space analyses to help inform which consumers are reluctant to purchase new technologies. Last, we began analysis of impacts of alternative energy technologies on Class 8 trucks to isolate those that may most efficaciously advance HDV efficiency and petroleum use reduction goals.

    CERN Document Server

    B Gibilisco, Michael; E Albert, Karen; N Mordeson, John; J Wierman, Mark; D Clark, Terry

    2014-01-01

    This book offers a comprehensive analysis of the social choice literature and shows, by applying fuzzy sets, how the use of fuzzy preferences, rather than that of strict ones, may affect the social choice theorems. To do this, the book explores the presupposition of rationality within the fuzzy framework and shows that the two conditions for rationality, completeness and transitivity, do exist with fuzzy preferences. Specifically, this book examines: the conditions under which a maximal set exists; the Arrow’s theorem;  the Gibbard-Satterthwaite theorem; and the median voter theorem.  After showing that a non-empty maximal set does exists for fuzzy preference relations, this book goes on to demonstrating the existence of a fuzzy aggregation rule satisfying all five Arrowian conditions, including non-dictatorship. While the Gibbard-Satterthwaite theorem only considers individual fuzzy preferences, this work shows that both individuals and groups can choose alternatives to various degrees, resulting in a so...

  12. Exploring the career choices of White and Black, Asian and Minority Ethnic women pharmacists: a qualitative study.

    Howells, Kelly; Bower, Peter; Hassell, Karen

    2017-12-26

    In the UK, a growing number of females entering pharmacy are women from Black, Asian and minority ethnic groups (BAME). Research shows that BAME women are more likely to work in the community sector and be self-employed locums than white women, and Asian women overrepresented in part-time, lower status roles. This study aims to explore the employment choices of white and BAME women pharmacists to see whether their diverse work patterns are the product of individual choices or other organisational factors. This study analyses 28 qualitative interviews conducted with 18 BAME and 10 white women pharmacists. The interview schedule was designed to explore early career choices, future career aspirations and key stages in making their career decisions. The findings show that white and BAME women are influenced by different factors in their early career choices. Cultural preferences for self-employment and business opportunities discourage BAME women from hospital sector jobs early in their careers. Resonating with other studies, the findings show that white and BAME women face similar barriers to career progression if they work part-time. Women working part-time are more likely to face workforce barriers, irrespective of ethnic origin. Cultural preferences may be preventing BAME women from entering the hospital sector. This research is important in the light of current debates about the future shape of pharmacy practice, as well as wider government policy objectives that seek to improve the working lives of health care professionals and promote racial diversity and equality in the workplace. © 2017 The Authors.

A sub study of Ramadan prospective diabetes study (2 which was conducted at the outpatient department of Baqai Institute of Diabetology and endocrinology, Karachi Pakistan in 2009 analyzed the food choices of patients with diabetes during Ramadan. Several irregularities regarding dietary intake and food choices were noted among the study participants. Although, the patients were counseled regarding diet before Ramadan, many did not follow the dietary advice. All patients had taken food at Iftar but majority of them preferred fried items like samosas, pakoras (fried snack, chicken rolls etc. these deeply fried items can lead to post Iftar hyperglycemia. Patients were also opted for fruit chat, dahibara and chanachaat at Iftar, higher load of these items can also worsen glycemic control. The striking finding was almost absence of meat (protein intake at Iftar but study from India showed increment of all three macronutrients during Ramadan (3. This may result in higher intake of items from carbohydrate and fat groups resulting in hyperglycemia after iftar. Intake of vegetables at Iftar was also negligible and hence the diet was not well balanced. The food choices at sahoor included roti, paratha (fried bread, slices, khajla, pheni, meat, egg and milk. Though it is advisable to take complex carbohydrates, protein and fat at sahoor as these are slowly digestible and can prevent hypoglycemia during fasting but khajla pheni are extremely rich in fat and carbohydrate content and should be avoided (4. However, paratha in 2 teaspoon of oil can be taken at sahoor.Patients with diabetes who fast during the month of Ramadan should have pre Ramadan dietary guidance and counseling session in order to modify their food preferences and choices during the holy month of Ramadan (4.

    Context effects in choice settings have received recent attention but little is known about the impact of context on choice consistency and the extent to which consumers apply choice heuristics. The sequence of alternatives in a choice set is examined here as one specific context effect. We compare...... how a change from a typical price order to a sensory order in wine menus affects consumer choice. We use pre-specified latent heuristic classes to analyse the existence of different choice processes, which begins to untangle the ‘black box’ of how consumers choose. Our findings indicate...... that in the absence of price order, consumers are less price-sensitive, pay more attention to visually salient cues, are less consistent in their choices and employ other simple choice heuristics more frequently than price. Implications for consumer research, marketing and consumer policy are discussed....

    The origins of this volume can be traced back to a conference on "Ethics, Economic and Business" organized by Columbia Busi­ ness School in March of 1993, and held in the splendid facilities of Columbia's Casa Italiana. Preliminary versions of several of the papers were presented at that meeting. In July 1994 the Fields Institute of Mathematical Sciences sponsored a workshop on "Geometry, Topology and Markets": additional papers and more refined versions of the original papers were presented there. They were published in their present versions in Social Choice and Wel­ fare, volume 14, number 2, 1997. The common aim of these workshops and this volume is to crystallize research in an area which has emerged rapidly in the last fifteen years, the area of topological approaches to social choice and the theory of games. The area is attracting increasing interest from social choice theorists, game theorists, mathematical econ­ omists and mathematicians, yet there is no authoritative collection of papers in the a...

  3. Decadal opportunities for space architects

    Science.gov (United States)

    Sherwood, Brent

    2012-12-01

    A significant challenge for the new field of space architecture is the dearth of project opportunities. Yet every year more young professionals express interest to enter the field. This paper derives projections that bound the number, type, and range of global development opportunities that may be reasonably expected over the next few decades for human space flight (HSF) systems so those interested in the field can benchmark their goals. Four categories of HSF activity are described: human Exploration of solar system bodies; human Servicing of space-based assets; large-scale development of space Resources; and Breakout of self-sustaining human societies into the solar system. A progressive sequence of capabilities for each category starts with its earliest feasible missions and leads toward its full expression. The four sequences are compared in scale, distance from Earth, and readiness. Scenarios hybridize the most synergistic features from the four sequences for comparison to status quo, government-funded HSF program plans. Finally qualitative, decadal, order-of-magnitude estimates are derived for system development needs, and hence opportunities for space architects. Government investment towards human planetary exploration is the weakest generator of space architecture work. Conversely, the strongest generator is a combination of three market drivers: (1) commercial passenger travel in low Earth orbit; (2) in parallel, government extension of HSF capability to GEO; both followed by (3) scale-up demonstration of end-to-end solar power satellites in GEO. The rich end of this scale affords space architecture opportunities which are more diverse, complex, large-scale, and sociologically challenging than traditional exploration vehicle cabins and habitats.

  11. Managing biological diversity

    Science.gov (United States)

    Samson, Fred B.; Knopf, Fritz L.

    1993-01-01

    Biological diversity is the variety of life and accompanying ecological processes (Off. Technol. Assess. 1987, Wilcove and Samson 1987, Keystone 1991). Conservation of biological diversity is a major environmental issue (Wilson 1988, Counc. Environ. Quality 1991). The health and future of the earth's ecological systems (Lubchenco et al. 1991), global climate change (Botkin 1990), and an ever-increasing rate in loss of species, communities, and ecological systems (Myers 1990) are among issues drawing biological diversity to the mainstream of conservation worldwide (Int. Union Conserv. Nat. and Nat. Resour. [IUCN] et al. 1991). The legal mandate for conserving biological diversity is now in place (Carlson 1988, Doremus 1991). More than 19 federal laws govern the use of biological resources in the United States (Rein 1991). The proposed National Biological Diversity Conservation and Environmental Research Act (H.R. 585 and S.58) notes the need for a national biological diversity policy, would create a national center for biological diversity research, and recommends a federal interagency strategy for ecosystem conservation. There are, however, hard choices ahead for the conservation of biological diversity, and biologists are grappling with how to set priorities in research and management (Roberts 1988). We sense disillusion among field biologists and managers relative to how to operationally approach the seemingly overwhelming charge of conserving biological diversity. Biologists also need to respond to critics like Hunt (1991) who suggest a tree farm has more biological diversity than an equal area of old-growth forest. At present, science has played only a minor role in the conservation of biological diversity (Weston 1992) with no unified approach available to evaluate strategies and programs that address the quality and quantity of biological diversity (Murphy 1990, Erwin 1992). Although actions to conserve biological diversity need to be clearly defined by

    People self-assess their relative ability when making career choices. Thus, confidence in their own abilities is likely an important factor for selection into various career paths. In a sample of 711 first-year students we examine whether there are systematic differences in confidence levels across fields of study. We find that our experimental confidence measures significantly vary between fields of study: While students in business related academic disciplines (Political Science, Law, Economics, and Business Administration) exhibit the highest confidence levels, students of Humanities range at the other end of the scale. This may have important implications for subsequent earnings and professions students select themselves in.

    This paper considers the role of reasons and arguments in the making of decisions. It is proposed that, when faced with the need to choose, decision makers often seek and construct reasons in order to resolve the conflict and justify their choice, to themselves and to others. Experiments that explore and manipulate the role of reasons are reviewed, and other decision studies are interpreted from this perspective. The role of reasons in decision making is considered as it relates to uncertainty, conflict, context effects, and normative decision rules.

    2004-01-01

    Full Text Available Background: An increasing number of medical schools are offering dual degree MD/MBA programs. Career choices and factors influencing students to enter these programs provide an indicator of the roles in which dual degree students will serve in health care as well as the future of dual degree programs. Purpose: Using career choice theory as a conceptual framework, career goals and factors influencing decisions to enter dual degree programs were assessed among dual degree medical students. Methods: Students enrolled at dual degree programs at six medical schools were surveyed and interviewed. A control group of traditional medical students was also surveyed. Results: Factors influencing students to seek both medical and business training are varied but are often related to a desire for leadership opportunities, concerns about change in medicine and job security and personal career goals. Most students expect to combine clinical and administrative roles. Conclusions: Students entering these programs do so for a variety of reasons and plan diverse careers. These findings can provide guidance for program development and recruitment for dual degree medical education programs

    2017-09-01

    The ongoing Finnish health and social service reform will expand choice by opening the market for competition between public and private service providers. This study examined the attitudes of primary care patients towards choice and which patient-related factors are associated with these attitudes. A sample of attenders during one week in health centres of 12 big cities and municipal consortiums (including seven outsourced local units) and in primary care units of one private company providing outsourced services for municipalities (aged 18-95, n=8128) was used. The questionnaire included questions on choice-related attitudes, sociodemographic factors, health status, use of health services and patient satisfaction. Of the responders, 77% regarded choice to be important, 49% perceived genuine opportunities to make choices and 35% were satisfied with the choice-relevant information. Higher age, low education, having a chronic illness, frequent use of services, having a personal physician and being satisfied with the physician and with waiting times were related to assigning more importance on choice. Younger patients, those with higher education as well as those with chronic illness regarded their opportunities of choosing the service provider and availability of choice-relevant information poorer. The Finnish primary care patients value choice, but they are critical of the availability of choice-relevant information. Choices of patients with complex health care needs should be supported by developing integrated care alternatives and by increasing the availability of information on existing care alternatives to meet their needs.

    Full Text Available Diversity is a phenomenon which is increasingly manifesting itself in the globalized society; therefore, it is observable in various areas of human activity, and thus also in the labour market and work teams. Age, sex, ethnicity and nationality, creed or disabilities are among the parameters of diversity. The aim of the article is to identify and evaluate the implementation of Diversity Management in workplaces, whilst bearing in mind researched factors of diversity. The results were gained by conducting a primary survey by questionnaire in organizations (n = 315. The results showed that a total of 41.9% of selected organizations operating in the Czech Republic implement Diversity Management. The largest part of organizations operate in the tertiary sector (69.7%. The survey results show the situation concerning Diversity Management in the selected organizations and support the oppinion that Diversity Management is a current global matter and its concerns all organizations. The research parameters influenced the application of Diversity Management in organizations (Cramer’s V is from 0.176 to 0.430. One of the recommendations for organizations is that they devote more attention to this phenomenon, as qualified human resources is on the decline and adequate attention will once again need to be devoted to groups of potential workers who have hitherto been overlooked. Diversity Management represents a new opportunity for organizations to build the employer’s good brand and attract knowledge workers.

  10. Compelling Research Opportunities using Isotopes

    Isotopes are vital to the science and technology base of the US economy. Isotopes, both stable and radioactive, are essential tools in the growing science, technology, engineering, and health enterprises of the 21st century. The scientific discoveries and associated advances made as a result of the availability of isotopes today span widely from medicine to biology, physics, chemistry, and a broad range of applications in environmental and material sciences. Isotope issues have become crucial aspects of homeland security. Isotopes are utilized in new resource development, in energy from bio-fuels, petrochemical and nuclear fuels, in drug discovery, health care therapies and diagnostics, in nutrition, in agriculture, and in many other areas. The development and production of isotope products unavailable or difficult to get commercially have been most recently the responsibility of the Department of Energy's Nuclear Energy program. The President's FY09 Budget request proposed the transfer of the Isotope Production program to the Department of Energy's Office of Science in Nuclear Physics and to rename it the National Isotope Production and Application program (NIPA). The transfer has now taken place with the signing of the 2009 appropriations bill. In preparation for this, the Nuclear Science Advisory Committee (NSAC) was requested to establish a standing subcommittee, the NSAC Isotope Subcommittee (NSACI), to advise the DOE Office of Nuclear Physics. The request came in the form of two charges: one, on setting research priorities in the short term for the most compelling opportunities from the vast array of disciplines that develop and use isotopes and two, on making a long term strategic plan for the NIPA program. This is the final report to address charge 1. NSACI membership is comprised of experts from the diverse research communities, industry, production, and homeland security. NSACI discussed research opportunities divided into three areas: (1

  15. Budget Constraints Affect Male Rats’ Choices between Differently Priced Commodities

    Kalenscher, Tobias

    2015-01-01

    Demand theory can be applied to analyse how a human or animal consumer changes her selection of commodities within a certain budget in response to changes in price of those commodities. This change in consumption assessed over a range of prices is defined as demand elasticity. Previously, income-compensated and income-uncompensated price changes have been investigated using human and animal consumers, as demand theory predicts different elasticities for both conditions. However, in these studies, demand elasticity was only evaluated over the entirety of choices made from a budget. As compensating budgets changes the number of attainable commodities relative to uncompensated conditions, and thus the number of choices, it remained unclear whether budget compensation has a trivial effect on demand elasticity by simply sampling from a different total number of choices or has a direct effect on consumers’ sequential choice structure. If the budget context independently changes choices between commodities over and above price effects, this should become apparent when demand elasticity is assessed over choice sets of any reasonable size that are matched in choice opportunities between budget conditions. To gain more detailed insight in the sequential choice dynamics underlying differences in demand elasticity between budget conditions, we trained N=8 rat consumers to spend a daily budget by making a number of nosepokes to obtain two liquid commodities under different price regimes, in sessions with and without budget compensation. We confirmed that demand elasticity for both commodities differed between compensated and uncompensated budget conditions, also when the number of choices considered was matched, and showed that these elasticity differences emerge early in the sessions. These differences in demand elasticity were driven by a higher choice rate and an increased reselection bias for the preferred commodity in compensated compared to uncompensated budget

  4. Environment and fuel choice

    International Nuclear Information System (INIS)

    Ellerman, A.D.

    1992-01-01

    The efficacy of environmental regulation as a determinant of fossil fuel choice is examined, with a focus on coal and natural gas in the United States market. It is thought that with the current concern over greenhouse gas emissions, gas would become the fuel of choice and would benefit from measures such as emission trading and carbon taxes. In the USA, in spite of environmental regulations set forth in the Clean Air Act, coal consumption has not decreased with respect to gas because coal is successfully competing on an economic and environmental level. Coal mine productivity has increased over the past 15 years and significant progress has been made in both reducing the emission forming materials in coal through better processing and reducing stack emissions via pollution control devices. An economic analysis of the premium that should attach to natural gas as compared to coal for power generation shows that an emissions trading premium on gas is not sufficient to compensate for the lower cost of coal. The advantages of natural gas for power generation lie in the lower capital and operating costs for combined cycle generation technology and the good prospects for a low, long-term equilibrium price for natural gas. Lower wellhead prices and combined cycle technology will cause gas to have a larger share of the electric utility market than coal in areas where transport economics are favorable. However, the economics of existing coal-fired plants favor continued use of coal, and the increase in gas use will depend on the rate at which new plants are built. 4 figs

  5. Measuring choice for adults with an intellectual disability - a factor analysis of the adapted daily choice inventory scale.

    2017-05-01

    For most people, choice making is an everyday occurrence, but for adults with an intellectual disability (ID), such opportunities are often limited, if not, absent. Defining choice, and related opportunity capacity and supports continue to feature prominently in academic, practice and policy discourse within the field of ID as reflected in the range of measures available. This paper examines the factor analytic properties of an adapted 14-item choice inventory scale. Presence and type of choice were recorded in wave 1 of the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing using a choice inventory scale adapted for the Irish context for 753 participants with ID over age 40 years. Analysis included both an exploratory and confirmatory factor analysis. Descriptive statistics on choice by type of living arrangement, type of interview (proxy, self or supported) and level of ID are presented. Exploratory factor analysis indicates good model fit when using both a 3-item and 4-item response with the 4-item version suggesting a two-factor model. Further exploration of this two-factor model through confirmatory factor analysis highlighted an improved fit for the 4-item model. Further improvement in model fit is found when four item pairs are co-varied within the model. Two broad types of choice were found to exist for adults with ID - everyday decisions and key life decisions. In addition, the factor analysis support for the inclusion of a 'no choice' response may help reduce the potential for missing data. © 2017 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    The authors examined several issues related to the motor learning benefits resulting from giving learners choices. In 2 experiments, participants practiced a novel task, throwing a lasso. In Experiment 1, giving learners a choice ostensibly irrelevant to performance (color of mat under target) resulted in enhanced learning relative to a control group. The choice group also reported more positive affect. Experiment 2 compared the effectiveness of task-irrelevant (mat color) versus task-relevant (video demonstrations of the skill) choices. In both choice groups, each participant was yoked to a participant in the other group, and each received the same mat color or saw the video demonstration, respectively, as chosen by their counterpart in the other group. In the control group, participants were yoked to their respective counterparts in each of the choice groups. On a retention test, the 2 choice groups did not differ from each other, but both outperformed the control group. The affective and learning effects seen when learners are given choices, and the fact that task-relevant and task-irrelevant choices resulted in similar learning benefits, are consistent with a content-neutral mechanism for the effects of choice on learning, as described in the OPTIMAL theory of motor learning (Wulf & Lewthwaite, 2016 ).

    Students’ science choices have long attracted attention in both public and research. Recently there has been a call for qualitative studies to explore how choices create a sense of fit for individual students. Therefore, this paper aims to study how science students’ choices of higher education...... side articulated as not too predictable, and on the other side appearing realistic and adjusted to the students’ sense of self. Third, the choice-narratives were informed, validated and adjusted in the students’ social network providing the students with a repertoire of viable pathways. The study...... demonstrates how cultural discourses about how a proper choice is made set the scene for the students’ choices. The study raises some concerns for science education. Improving students’ interests in science alone might not lead to increased admission as several interests equally intervene. To attract more...

    1991-01-01

    This study focused on the factors that influence students' choice of an allied health profession. A survey of 153 students in three allied health programs at the University of Connecticut revealed that "the need to help others," "prestige," "professional autonomy," "opportunities for advancement," "income potential," and "the effect of the specialty on family and personal life," were the major influencers of career choice among allied health students. Only a few students regarded malpractice suits and AIDS as negative influencers. While medical laboratory science majors regarded these as important factors, dietetics and physical therapy majors did not. The article suggests further use of these findings by program directors and career counselors.

    Full Text Available Motherhood has been perceived as choice in the developed world after the liberalisation of abortion. However, this choice can be extremely anxiety provoking for women, especially in times when the ideology of choice dominates our lives in all possible ways. The paper shows how psychotherapy and psychoanalysis look at this anxiety, it reflects on how family relations are often the traumatic kernel behind this choice, and how the changes that women experience in today's times contribute to the increase of anxiety related to reproduction.

    2017-01-01

    Abstract People often neglect opportunity costs: They do not fully take into account forgone alternatives outside of a particular choice set. Several scholars have suggested that poor people should be more likely to spontaneously consider opportunity costs, because budget constraints should lead to an increased focus on trade‐offs. We did not find support for this hypothesis in five high‐powered experiments (total N = 2325). The experiments used different products (both material and experiential) with both high and low prices (from $8.50 to $249.99) and different methods of reminding participants of opportunity costs. High‐income and low‐income participants showed an equally strong decrease in willingness to buy when reminded of opportunity costs, implying that both the rich and the poor neglect opportunity costs. © 2017 The Authors Journal of Behavioral Decision Making Published by John Wiley & Sons Ltd.

    The expected positive link between diversity management and organisational efficiency is often used as a reason for pursuing diversity management and equal employment opportunity programmes. However, this positive link is only supported to a limited degree by in-depth empirical research...... and therefore it is often based on normative expectations. Recent research has further indicated that the link between diversity and efficiency may be more complex and cannot a priori be taken for granted. This article argues that some theoretical rethinking of the issues is necessary and suggests...... that the combination of more theoretical cross fertilisation and in-depth research may be the way forward. Based on our own empirical research, barriers preventing a positive link between diversity and efficiency can come in different forms and our case studies illustrate situations where both containing...

  18. Lanthanide co-ordination frameworks: Opportunities and diversity

    2005-01-01

    Significant successes have been made over recent years in preparing co-ordination framework polymers that show macroscopic material properties, but in the vast majority of cases this has been achieved with d-block metal-based systems. Lanthanide co-ordination frameworks also offer attractive properties in terms of their potential applications as luminescent, non-linear optical and porous materials. However, lanthanide-based systems have been far less studied to date than their d-block counterparts. One possible reason for this is that the co-ordination spheres of lanthanide cations are more difficult to control and, in the absence of design strategies for lanthanide co-ordination frameworks, it is significantly more difficult to target materials with specific properties. However, this article highlights some of the exciting possibilities that have emerged from the earliest investigations in this field with new topological families of compounds being discovered from relatively simple framework components, including unusual eight, seven and five-connected framework systems. Our own research, as well as others, is leading to a much greater appreciation of the factors that control framework formation and the resultant observed topologies of these polymers. As this understanding develops targeting particular framework types will become more straightforward and the development of designed polyfunctional materials more accessible. Thus, it can be seen that lanthanide co-ordination frameworks have the potential to open up previously unexplored directions for materials chemistry. This article focuses on the underlying concepts for the construction of these enticing and potentially highly important materials

  19. Industrial opportunities - offshore

    International Nuclear Information System (INIS)

    Gerrits, D.J.

    1998-01-01

    Industrial opportunities available in the Canadian offshore petroleum industry are discussed. Oil has been produced offshore from Nova Scotia since 1992, and offshore from Newfoundland since 1997. Special needs that must be addressed in offshore operations in eastern Canada such as the cold North Atlantic environment, isolation, logistics, safety, and quality assurance, are examined. The most obvious opportunities lie with the designing, building and installing the facilities needed to extract oil and gas from beneath the sea floor and transport it to market. However, there are also opportunities in designing and fabricating clothing, customized food containers and other equipment for offshore needs. Short term opportunities also exist in the decommissioning of depleted production fields and their facilities. One of the greatest obstacles facing new entrants into the offshore oil and gas industry is the lack of a track record. To meet this challenge, the ability to seek out partners to pursue local and international opportunities through joint ventures, strategic alliances and technology sharing partnering arrangements is of great importance. It may be the difference between success and failure. 6 figs

    Addressing the causes and consequences of environmental degradation presents significant challenges for humankind. This paper considers what ergonomics/human factors (E/HF) professionals can contribute to understanding and tackling some of the issues that arise through the movement towards a more environmentally sustainable economy. These issues are considered in relation to work in green industries (specifically, sustainable energy production, recycling and organic food production), and there is a need to ensure that these jobs are safe and healthy; the design of products and systems that are 'environmentally friendly' to facilitate their acceptability and use and how E/HF professionals can contribute to understanding and promoting behavioural change relating to environmental choices. The activities of some international organisations in this area are identified and the potential for E/HF involvement is considered. The implications for the E/HF profession are discussed. This paper considers how ergonomics/human factors professionals can contribute to the movement towards more sustainable and 'environmentally friendly' design and work. Potential challenges and opportunities are discussed in relation to jobs in green industries, products and systems and behaviour change.

    Soybean canopy outline is an important trait used to understand light interception ability, canopy closure rates, row spacing response, which in turn affects crop growth and yield, and directly impacts weed species germination and emergence. In this manuscript, we utilize a methodology that constructs geometric measures of the soybean canopy outline from digital images of canopies, allowing visualization of the genetic diversity as well as a rigorous quantification of shape parameters. Our choice of data analysis approach is partially dictated by the need to efficiently store and analyze large datasets, especially in the context of planned high-throughput phenotyping experiments to capture time evolution of canopy outline which will produce very large datasets. Using the Elliptical Fourier Transformation (EFT) and Fourier Descriptors (EFD), canopy outlines of 446 soybean plant introduction (PI) lines from 25 different countries exhibiting a wide variety of maturity, seed weight, and stem termination were investigated in a field experiment planted as a randomized complete block design with up to four replications. Canopy outlines were extracted from digital images, and subsequently chain coded, and expanded into a shape spectrum by obtaining the Fourier coefficients/descriptors. These coefficients successfully reconstruct the canopy outline, and were used to measure traditional morphometric traits. Highest phenotypic diversity was observed for roundness, while solidity showed the lowest diversity across all countries. Some PI lines had extraordinary shape diversity in solidity. For interpretation and visualization of the complexity in shape, Principal Component Analysis (PCA) was performed on the EFD. PI lines were grouped in terms of origins, maturity index, seed weight, and stem termination index. No significant pattern or similarity was observed among the groups; although interestingly when genetic marker data was used for the PCA, patterns similar to canopy

    National Laboratories often have unique facilities that cannot be normally found at universities, and that provide unique opportunities to perform research using world class instrumentation in collaboration with teams of experts. This synergy of expertise and world-class facilities also offers unique opportunities for mentoring and training of students in settings different from the university environment. In this talk I will discuss the opportunities of scientific research, mentoring and training at the Spallation Neutron Source (SNS) and the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory. The SNS is the world's most intense pulsed accelerator-based neutron source, the HFIR is the highest flux reactor-based neutron source for condensed matter research in the United States, the combination of these provides neutron scattering capabilities unavailable anywhere else in the world. The SNS and the HFIR at ORNL are funded by the Division of Scientific User Facilities, Office of Basic Energy Sciences, US. Department of Energy.

  19. Resurgence as Choice.

    Science.gov (United States)

    Shahan, Timothy A; Craig, Andrew R

    2017-08-01

    Resurgence is typically defined as an increase in a previously extinguished target behavior when a more recently reinforced alternative behavior is later extinguished. Some treatments of the phenomenon have suggested that it might also extend to circumstances where either the historic or more recently reinforced behavior is reduced by other non-extinction related means (e.g., punishment, decreases in reinforcement rate, satiation, etc.). Here we present a theory of resurgence suggesting that the phenomenon results from the same basic processes governing choice. In its most general form, the theory suggests that resurgence results from changes in the allocation of target behavior driven by changes in the values of the target and alternative options across time. Specifically, resurgence occurs when there is an increase in the relative value of an historically effective target option as a result of a subsequent devaluation of a more recently effective alternative option. We develop a more specific quantitative model of how extinction of the target and alternative responses in a typical resurgence paradigm might produce such changes in relative value across time using a temporal weighting rule. The example model does a good job in accounting for the effects of reinforcement rate and related manipulations on resurgence in simple schedules where Behavioral Momentum Theory has failed. We also discuss how the general theory might be extended to other parameters of reinforcement (e.g., magnitude, quality), other means to suppress target or alternative behavior (e.g., satiation, punishment, differential reinforcement of other behavior), and other factors (e.g., non- contingent versus contingent alternative reinforcement, serial alternative reinforcement, and multiple schedules).

  20. Search predicts and changes patience in intertemporal choice.

    Reeck, Crystal; Wall, Daniel; Johnson, Eric J

    2017-11-07

    Intertemporal choice impacts many important outcomes, such as decisions about health, education, wealth, and the environment. However, the psychological processes underlying decisions involving outcomes at different points in time remain unclear, limiting opportunities to intervene and improve people's patience. This research examines information-search strategies used during intertemporal choice and their impact on decisions. In experiment 1, we demonstrate that search strategies vary substantially across individuals. We subsequently identify two distinct search strategies across individuals. Comparative searchers, who compare features across options, discount future options less and are more susceptible to acceleration versus delay framing than integrative searchers, who integrate the features of an option. Experiment 2 manipulates search using an unobtrusive method to establish a causal relationship between strategy and choice, randomly assigning participants to conditions promoting either comparative or integrative search. Again, comparative search promotes greater patience than integrative search. Additionally, when participants adopt a comparative search strategy, they also exhibit greater effects of acceleration versus delay framing. Although most participants reported that the manipulation did not change their behavior, promoting comparative search decreased discounting of future rewards substantially and speeded patient choices. These findings highlight the central role that heterogeneity in psychological processes plays in shaping intertemporal choice. Importantly, these results indicate that theories that ignore variability in search strategies may be inadvertently aggregating over different subpopulations that use very different processes. The findings also inform interventions in choice architecture to increase patience and improve consumer welfare. Copyright © 2017 the Author(s). Published by PNAS.

    2012-09-01

    Although many anticipate that there will be an eventual shortage of practicing nephrologists, a complete understanding is lacking regarding the current factors that lead US adult nephrology fellows to choose nephrology as a career and their satisfaction with this choice. It is of great concern that interest in obtaining nephrology fellowship training continues to decline in the United States, especially among US medical graduates, and the reasons for this are unclear. The exposure that students and residents have to nephrology is likely to play an important role in the career choices that they make and their ultimate satisfaction with this career choice is likely influenced by several factors, including job opportunities. Some of the findings presented here suggest that there may be a high percentage of nephrology fellows who are dissatisfied with their career choice. Failure to understand the factors that influence trainees to choose nephrology as a career and those that affect their satisfaction with this choice may impair the ability to graduate a sufficient number of nephrologists to meet projected demand. In this article, a number of variables related to the choice of nephrology as a career and satisfaction with a career in nephrology are discussed. Some steps that the nephrology training community might take to help promote interest in nephrology and optimize the satisfaction that nephrology graduates derive from their careers are also proposed.

  2. Investment choice under uncertainty: A review essay

    Directory of Open Access Journals (Sweden)

    Trifunović Dejan

    2005-01-01

    Full Text Available An investment opportunity whose return is perfectly predictable, hardly exists at all. Instead, investor makes his decisions under conditions of uncertainty. Theory of expected utility is the main analytical tool for description of choice under uncertainty. Critics of the theory contend that individuals have bounded rationality and that the theory of expected utility is not correct. When agents are faced with risky decisions they behave differently, conditional on their attitude towards risk. They can be risk loving, risk averse or risk neutral. In order to make an investment decision it is necessary to compare probability distribution functions of returns. Investment decision making is much simpler if one uses expected values and variances instead of probability distribution functions.

  3. Commitment-based action: Rational choice theory and contrapreferential choice

    Directory of Open Access Journals (Sweden)

    Radovanović Bojana

    2014-01-01

    Full Text Available This paper focuses on Sen’s concept of contrapreferential choice. Sen has developed this concept in order to overcome weaknesses of the rational choice theory. According to rational choice theory a decision-maker can be always seen as someone who maximises utility, and each choice he makes as the one that brings to him the highest level of personal wellbeing. Sen argues that in some situations we chose alternatives that bring us lower level of wellbeing than we could achieve if we had chosen some other alternative available to us. This happens when we base our decisions on moral principles, when we act out of duty. Sen calls such action a commitment-based action. When we act out of commitment we actually neglect our preferences and thus we make a contrapreferential choice, as Sen argues. This paper shows that, contrary to Sen, a commitment-based action can be explained within the framework of rational choice theory. However, when each choice we make can be explained within the framework of rational choice theory, when in everything we do maximisation principle can be loaded, then the variety of our motives and traits is lost, and the explanatory power of the rational choice theory is questionable.

    2016-01-01

    We estimate the willingness-to-pay for conserving crop diversity in the Czech Republic. Discrete choice experiments are used to elicit preferences for the conservation of wine, hop, and fruit tree varieties, while a double-bounded dichotomous choice approach is used to elicit preferences for the conservation of unspecified, "general" crop diversity. The WTP values are derived for both of these contingent products from a sample representative of the general Czech population (n=731) and a sampl...

    Results: A total of six (3% students were considering Dermatology as their first choice, while it was the second choice for seven students (4.7%. Of the participants, 118 (60.8% found ′the difficulty of getting into a Dermatology residency programme′ to be the least attractive factor. Factors that significantly attracted medical students to consider Dermatology as a career choice were the appeal of being a dermatologist, how dermatologists lead a satisfying family life, reliance on clinical diagnostic skills and research opportunities in Dermatology (P = 0.004, 0.024, 0.039 and 0.010, respectively. Conclusions: A variety of factors influenced the medical students of KSAU-HS when choosing a future specialty. Identification of these factors can help medical student mentors and residency training programme directors to motivate students choose specialties that are limited in our nation.

    2013-03-01

    Intensive agricultural practices and current western consumption patterns are associated with increased ecological pressure. One way to reduce the ecological impact could be a shift to more sustainable food choices. This study investigates consumer opinions towards a series of food choices with a lower ecological impact. The investigated food choices range from well-known meat substitutes to alternatives which are more radical or innovative and that require an adaptation of food habits and cultural patterns. Results are obtained through a survey among 221 Flemish respondents in Spring 2011. Many consumers underestimate the ecological impact of animal production. Well-known alternatives such as organic meat, moderation of meat consumption and sustainable fish are accepted, although willingness to pay is clearly lower than willingness to consume. Consumers are more reluctant to alternatives that (partly) ban or replace meat in the meal. Opportunities of introducing insects currently appear to be non-existent. Five consumer segments were identified based on self-evaluated ecological footprint and personal relevance of the ecological footprint. The segments were termed Conscious, Active, Unwilling, Ignorant and Uncertain. A profile in terms of demographics, attitudinal and behavioral characteristics is developed for each segments, and conclusions with respect to opportunities for sustainable food choices are discussed.

  13. User Frustrations as Opportunities

    Directory of Open Access Journals (Sweden)

    Michael Weiss

    2012-04-01

    Full Text Available User frustrations are an excellent source of new product ideas. Starting with this observation, this article describes an approach that entrepreneurs can use to discover business opportunities. Opportunity discovery starts with a problem that the user has, but may not be able to articulate. User-centered design techniques can help elicit those latent needs. The entrepreneur should then try to understand how users are solving their problem today, before proposing a solution that draws on the unique skills and technical capabilities available to the entrepreneur. Finally, an in-depth understanding of the user allows the entrepreneur to hone in on the points of difference and resonance that are the foundation of a strong customer value proposition.

    A new role for the deregulated electric utilities in the energy services market or performance contracting markets was discussed. It was argued that in view of the long tradition of close customer contact, distribution utilities are in a good position to leverage their relationship with their customers to expand the range of products and services that the ''utility'' provides to them. Real time pricing, energy services, HVAC maintenance and operation are just some of the areas where the distribution utility''s linkage to customers could be used to good advantage. Some case histories, and a list of potential product and service opportunities in the commercial/industrial and residential sectors were provided. Some of the potential pitfalls were also identified for utilities that wish to pursue these opportunities. These pitfalls included legal, marketing, risk management and funding issues

    Opportunities for expanding the propane market in North America are discussed. The goal of change should be to enhance client satisfaction and loyalty. The current customer base is largely comprised of pick-up trucks, vans and buses in commercial fleet service, police and similar fleet service and privately owned vehicles. Opportunities for the expansion of propane exist due to: vehicles being kept and lasting longer, allowing a longer pay-back time; exhaust emission standards becoming more stringent; the possible introduction of emission standards for substances currently not controlled; and properly combusted CO 2 emissions that are at least 12% lower than gasoline. The continuing development of engine fuel management systems, application of extensive road/highway experience, matching supply and refuelling infrastructure to consumer demands, application in air quality non-attainment areas, and original equipment manufacturer, government and industry cooperation are discussed. 8 figs

    2015-02-01

    We describe what can be gained from connecting cognition and consumer choice by discussing two contexts ripe for interaction between the two fields. The first-context effects on choice-has already been addressed by cognitive science yielding insights about cognitive process but there is promise for more interaction. The second is learning and representation in choice where relevant theories in cognitive science could be informed by consumer choice, and in return, could pose and answer new questions. We conclude by discussing how these two fields of research stand to benefit from more interaction, citing examples of how interfaces of cognitive science with other fields have been illuminating for theories of cognition.

    Hsu, Ming; Yoon, Carolyn

    2015-10-01

    We review progress and challenges relating to scientific and applied goals of the nascent field of consumer neuroscience. Scientifically, substantial progress has been made in understanding the neurobiology of choice processes. Further advances, however, require researchers to begin clarifying the set of developmental and cognitive processes that shape and constrain choices. First, despite the centrality of preferences in theories of consumer choice, we still know little about where preferences come from and the underlying developmental processes. Second, the role of attention and memory processes in consumer choice remains poorly understood, despite importance ascribed to them in interpreting data from the field. The applied goal of consumer neuroscience concerns our ability to translate this understanding to augment prediction at the population level. Although the use of neuroscientific data for market-level predictions remains speculative, there is growing evidence of superiority in specific cases over existing market research techniques.

    DEFF Research Database (Denmark)

    Fosgerau, Mogens; Melo, Emerson; de Palma, André

    2017-01-01

    This paper establishes a general equivalence between discrete choice and rational inattention models. Matejka and McKay (2015, AER) showed that when information costs are modelled using the Shannon entropy, the result- ing choice probabilities in the rational inattention model take the multinomial...... logit form. We show that when information costs are modelled using a class of generalized entropies, then the choice probabilities in any rational inattention model are observationally equivalent to some additive random utility discrete choice model and vice versa. This equivalence arises from convex......- analytic properties of the random utility model. Thus any additive random utility model can be given an interpretation in terms of boundedly rational behavior. We provide examples of this equivalence utilizing the nested logit model, an empirically relevant random utility model allowing for flexible...

    An analysis of factors affecting migration is presented. The authors "extend the investigation of the roles of information, intervening opportunities, and psychic costs by focussing on differences in migrant destinations with respect to the deterring effect of distance. [They develop] a reservation-wage model of migration which implies that the distance effect is weaker for high-wage destinations and stronger for low-wage destinations." The model is tested using data for Brazil, Japan, Mexico, the United States, and Venezuela. excerpt

    Actual results have shown that the Construction Industry Institute (CII) offers significant opportunities for improvement in cost, schedule, and quality on most projects, and in particular, on large projects. This paper reviews the state of the construction industry, discusses how its problems are being addressed by CII, and addresses potential opportunities through the application of CII research products. CII is meeting the challenge of the industry. Just like the challenge of Department of Energy's Super Conducting Super Collider. With $1.2 billion worth of construction to be constructed during the 90s, the opportunities for innovation appear to be great. Every effort should be made while the projects are still on the high part of cost influence curve to use modern management methods and approaches to executing its work. Proper attention to all the inputs to project design is absolutely essential. Scope definition and control techniques have been developed by CII which can be used. Work packaging for the most efficient execution of engineering and construction are available as well. Approaches, incentives, and contracting strategies have also been researched by CII. Constructability programs virtually always guarantee a savings of at least 10 percent. Partnership arrangements can reduce the size of overhead for all participants in the process and eliminate the typical adversarial climates which tend to predominate on a construction project. SSC Laboratories and the PB-MK team have the opportunity to take the initiative now to make the 21st Century SSC a construction project which is executed in the 21st Century manner

  3. Evoked emotions predict food choice.

    2014-01-01

    In the current study we show that non-verbal food-evoked emotion scores significantly improve food choice prediction over merely liking scores. Previous research has shown that liking measures correlate with choice. However, liking is no strong predictor for food choice in real life environments. Therefore, the focus within recent studies shifted towards using emotion-profiling methods that successfully can discriminate between products that are equally liked. However, it is unclear how well scores from emotion-profiling methods predict actual food choice and/or consumption. To test this, we proposed to decompose emotion scores into valence and arousal scores using Principal Component Analysis (PCA) and apply Multinomial Logit Models (MLM) to estimate food choice using liking, valence, and arousal as possible predictors. For this analysis, we used an existing data set comprised of liking and food-evoked emotions scores from 123 participants, who rated 7 unlabeled breakfast drinks. Liking scores were measured using a 100-mm visual analogue scale, while food-evoked emotions were measured using 2 existing emotion-profiling methods: a verbal and a non-verbal method (EsSense Profile and PrEmo, respectively). After 7 days, participants were asked to choose 1 breakfast drink from the experiment to consume during breakfast in a simulated restaurant environment. Cross validation showed that we were able to correctly predict individualized food choice (1 out of 7 products) for over 50% of the participants. This number increased to nearly 80% when looking at the top 2 candidates. Model comparisons showed that evoked emotions better predict food choice than perceived liking alone. However, the strongest predictive strength was achieved by the combination of evoked emotions and liking. Furthermore we showed that non-verbal food-evoked emotion scores more accurately predict food choice than verbal food-evoked emotions scores.

The typology builds on two literatures: power transition theory, and the more recent “assertiveness” discourse in the West. Drawing from a range of cases...... in both the economic and security domains, the article argues that China’s multilateralism is diverse, and that it cannot be un-problematically characterized as either status-quo or revisionist in nature. However, the general trend appears to be towards engagement, but with an assertive tact as China......’s interests become further entangled in the business of international institutions....

  6. Modeling one-choice and two-choice driving tasks.

    Ratcliff, Roger

    2015-08-01

    An experiment is presented in which subjects were tested on both one-choice and two-choice driving tasks and on non-driving versions of them. Diffusion models for one- and two-choice tasks were successful in extracting model-based measures from the response time and accuracy data. These include measures of the quality of the information from the stimuli that drove the decision process (drift rate in the model), the time taken up by processes outside the decision process and, for the two-choice model, the speed/accuracy decision criteria that subjects set. Drift rates were only marginally different between the driving and non-driving tasks, indicating that nearly the same information was used in the two kinds of tasks. The tasks differed in the time taken up by other processes, reflecting the difference between them in response processing demands. Drift rates were significantly correlated across the two two-choice tasks showing that subjects that performed well on one task also performed well on the other task. Nondecision times were correlated across the two driving tasks, showing common abilities on motor processes across the two tasks. These results show the feasibility of using diffusion modeling to examine decision making in driving and so provide for a theoretical examination of factors that might impair driving, such as extreme aging, distraction, sleep deprivation, and so on.

  7. Caveat Emptor! The Rhetoric of Choice in Food Politics

    Directory of Open Access Journals (Sweden)

    Andrew Calabrese

    2017-11-01

    Full Text Available This project is about a form of corporate predation that entails both policy influence and cultural legitimation. Neoliberal explanations of the inability of citizens to thrive in the current socio- economic condition typically rest on a combination of victim-blaming and appeals to the individualistic rhetoric that assumes we all enjoy equality of opportunity and freedom of choice. It is common for corporate lobbyists, and politicians under their influence, to argue against consumer protection on the grounds that such efforts are paternalistic, and that they therefore undermine consumer sovereignty. By this logic, illnesses that are highly correlated to diet are problems that consumers can avoid, and it is not the duty of food companies or government to prevent consumers from making “bad choices.” Implicit in this moralistic narrative is that consumers have sufficient knowledge about the alternatives to enable them to make “good choices.” Major food lobbies use their political influence to oppose government regulations of food, based on the reasoning that consumers deserve the right to choose. Food industry groups also will sometimes invest heavily to prevent legal requirements to disclose information that might enable consumers to make informed choices, creating a predatory double-bind. In this essay, I discuss how the rhetoric of choice is employed by the food industry, how it is formulated within the political context of the United States, and how that rhetoric poses threats to food systems globally.

  8. The impact of sex-role reversal on the diversity of the major histocompatibility complex: Insights from the seahorse (Hippocampus abdominalis

    Directory of Open Access Journals (Sweden)

    Wilson Anthony B

    2011-05-01

    Full Text Available Abstract Background Both natural and sexual selection are thought to influence genetic diversity, but the study of the relative importance of these two factors on ecologically-relevant traits has traditionally focused on species with conventional sex-roles, with male-male competition and female-based mate choice. With its high variability and significance in both immune function and olfactory-mediated mate choice, the major histocompatibility complex (MHC/MH is an ideal system in which to evaluate the relative contributions of these two selective forces to genetic diversity. Intrasexual competition and mate choice are both reversed in sex-role reversed species, and sex-related differences in the detection and use of MH-odor cues are expected to influence the intensity of sexual selection in such species. The seahorse, Hippocampus abdominalis, has an exceptionally highly developed form of male parental care, with female-female competition and male mate choice. Results Here, we demonstrate that the sex-role reversed seahorse has a single MH class II beta-chain gene and that the diversity of the seahorse MHIIβ locus and its pattern of variation are comparable to those detected in species with conventional sex roles. Despite the presence of only a single gene copy, intralocus MHIIβ allelic diversity in this species exceeds that observed in species with multiple copies of this locus. The MHIIβ locus of the seahorse exhibits a novel expression domain in the male brood pouch. Conclusions The high variation found at the seahorse MHIIβ gene indicates that sex-role reversed species are capable of maintaining the high MHC diversity typical in most vertebrates. Whether such species have evolved the capacity to use MH-odor cues during mate choice is presently being investigated using mate choice experiments. If this possibility can be rejected, such systems would offer an exceptional opportunity to study the effects of natural selection in isolation

    2016-12-01

    We generalize the ordinary aggregation process to allow for choice. In ordinary aggregation, two random clusters merge and form a larger aggregate. In our implementation of choice, a target cluster and two candidate clusters are randomly selected and the target cluster merges with the larger of the two candidate clusters. We study the long-time asymptotic behavior and find that as in ordinary aggregation, the size density adheres to the standard scaling form. However, aggregation with choice exhibits a number of different features. First, the density of the smallest clusters exhibits anomalous scaling. Second, both the small-size and the large-size tails of the density are overpopulated, at the expense of the density of moderate-size clusters. We also study the complementary case where the smaller candidate cluster participates in the aggregation process and find an abundance of moderate clusters at the expense of small and large clusters. Additionally, we investigate aggregation processes with choice among multiple candidate clusters and a symmetric implementation where the choice is between two pairs of clusters.

    2015-01-01

    Island biotas provide a great opportunity to study not only the phylogeographic patterns of a group of species, but also to explore the differentiation in their coevolutionary interactions. Drosophila and their parasitoids are exemplary systems for studying complex interaction patterns. However, there is a lack of studies combining interaction-based and molecular marker-based methods. We applied an integrated approach combining phylogeography, interaction, and host-choice behavior studies, with the aim to understand how coevolutionary interactions evolve in Drosophila-parasitoid island populations. The study focused on the three most abundant Drosophila species in Ryukyu archipelago and Taiwan: D. albomicans, D. bipectinata, and D. takahashii, and the Drosophila-parasitoid Leptopilina ryukyuensis. We determined mitochondrial COI haplotypes for samples representing five island populations of Drosophila and four island populations of L. ryukyuensis. We additionally sequenced parts of the autosomal Gpdh for Drosophila samples, and the ITS2 for parasitoid samples. Phylogenetic and coalescent analyses were used to test for demographic events and to place them in a temporal framework. Geographical differences in Drosophila-parasitoid interactions were studied in host-acceptance, host-suitability, and host-choice experiments. All four species showed species-specific phylogeographic patterns. A general trend of the haplotype diversity increasing towards the south was observed. D. albomicans showed very high COI haplotype diversity, and had the most phylogeographically structured populations, with differentiation into the northern and the southern population-group, divided by the Kerama gap. Differentiation in host suitability was observed only between highly structured populations of D. albomicans, possibly facilitated by restricted gene flow. Differentiation in host-acceptance in D. takahashii, and host-acceptance and host-choice in L. ryukyuensis was found, despite there

  18. CHOICE IN CONTEXT: RATIONALITY, CONTINGENCY AND RISK IN THE DIVIDEND POLICY

    Directory of Open Access Journals (Sweden)

    Narcis Tulbure

    2015-05-01

    Full Text Available This paper is a critical review of the recent literature regarding the dividend policy with regards to the different conceptualizations of rationality demonstrated by managers of companies or individual investors. This approach gives us the opportunity to reassess the latest contributions to dividend policy analysis and to adopt an alternative perspective to those of authors that have split the literature on dividends in the normative vs. descriptive approaches, empirical vs. theoretical contributions, according to the distinct paradigms various approaches illustrate, or according to chronological criteria. We surmise that the issue of rationality / irrationality occasions a better understanding of the latest contributions to corporate finance from the subfields of behavioral finance and of cultural finance. Such contributions challenge the premises of rational choice, one that is foundational for the neoclassic paradigm. Behavioral corporate finance and cultural corporate finance underline the role of psychological and socio-cultural factors for the dividend policy. They facilitate the emergence of notions of situated / contingent rationality considered responsible for the diverse shapes taken by the financial policies of the corporation.

  19. Which Fish Should I Eat? Perspectives Influencing Fish Consumption Choices

    Choi, Anna L.; Karagas, Margaret R.; Mariën, Koenraad; Rheinberger, Christoph M.; Schoeny, Rita; Sunderland, Elsie; Korrick, Susan

    2012-01-01

    Background: Diverse perspectives have influenced fish consumption choices. Objectives: We summarized the issue of fish consumption choice from toxicological, nutritional, ecological, and economic points of view; identified areas of overlap and disagreement among these viewpoints; and reviewed effects of previous fish consumption advisories. Methods: We reviewed published scientific literature, public health guidelines, and advisories related to fish consumption, focusing on advisories targeted at U.S. populations. However, our conclusions apply to groups having similar fish consumption patterns. Discussion: There are many possible combinations of matters related to fish consumption, but few, if any, fish consumption patterns optimize all domains. Fish provides a rich source of protein and other nutrients, but because of contamination by methylmercury and other toxicants, higher fish intake often leads to greater toxicant exposure. Furthermore, stocks of wild fish are not adequate to meet the nutrient demands of the growing world population, and fish consumption choices also have a broad economic impact on the fishing industry. Most guidance does not account for ecological and economic impacts of different fish consumption choices. Conclusion: Despite the relative lack of information integrating the health, ecological, and economic impacts of different fish choices, clear and simple guidance is necessary to effect desired changes.

In addition, policy and fishery management inter-ventions will be necessary to ensure long-term availability of fish as an important source of human nutrition. PMID:22534056

  20. Voice and choice by delegation.

    2013-02-01

    In many Western countries, options for citizens to influence public services are increased to improve the quality of services and democratize decision making. Possibilities to influence are often cast into Albert Hirschman's taxonomy of exit (choice), voice, and loyalty. In this article we identify delegation as an important addition to this framework. Delegation gives individuals the chance to practice exit/choice or voice without all the hard work that is usually involved in these options. Empirical research shows that not many people use their individual options of exit and voice, which could lead to inequality between users and nonusers. We identify delegation as a possible solution to this problem, using Dutch health care as a case study to explore this option. Notwithstanding various advantages, we show that voice and choice by delegation also entail problems of inequality and representativeness.

  3. Good Choice, Bad Judgment: How Choice Under Uncertainty Generates Overoptimism.

    Tong, Jordan; Feiler, Daniel; Ivantsova, Anastasia

    2018-02-01

    We examine a fundamental feature of choice under uncertainty: Overestimating an alternative makes one more likely to choose it. If people are naive to this structural feature, then they will tend to have erroneously inflated expectations for the alternatives they choose. In contrast to theories of motivated reasoning, this theory suggests that individuals will overestimate chosen alternatives even before they make their choice. In four studies, we found that students and managers exhibited behavior consistent with naïveté toward this relationship between estimation error and choice, leaving them overoptimistic about their chosen alternatives. This overoptimism from choosing positive error is exacerbated when the true values of the alternatives are close together, when there is more uncertainty about the values of alternatives, and when there are many alternatives to choose from. Our results illustrate how readily overoptimism emerges as a result of statistical naïveté, even in the absence of a desire to justify one's decision after the choice.

    Two-year colleges (2YCs) play a critical role in geoscience education in the United States. Nearly half of the undergraduate students who take introductory geoscience do so at a 2YC. With awide reach and diverse student populations, 2YCs may be key to producing a well-trained, diverse and sufficiently large geoscience workforce. However, faculty at 2YCs often face many barriers to professional development including lack of financial resources, heavy and inflexible teaching loads, lack of awareness of opportunities, and few professional development resources/events targeted at their needs. As an example, at the 2009 GSA meeting in Portland, fewer than 80 of the 6500 attendees were from community colleges, although this was more than twice the 2YC faculty attendance the previous year. Other issues include the isolation described by many 2YC geoscience faculty who may be the only full time geoscientist on a campus and challenges faced by adjunct faculty who may have even fewer opportunities for professional development and networking with other geoscience faculty. Over the past three years we have convened several workshops and events for 2YC geoscience faculty including technical sessions and a workshop on funding opportunities for 2YC faculty at GSA annual meetings, a field trip and networking event at the fall AGU meeting, a planning workshop that examined the role of 2YCs in geoscience education and in broadening participation in the geosciences, two workshops supporting use of the 'Math You Need, When You Need It' educational materials that included a majority of 2YC faculty, and marine science summer institutes offered by COSEE-Pacific Partnerships for 2YC faculty. Our experience indicates that 2YC faculty desire professional development opportunities when the experience is tailored to the needs and character of their students, programs, and institutions. The content of the professional development opportunity must be useful to 2YC faculty -workshops and

    2015-12-01

    Bladder cancer represents one of the ten most prevalent cancers worldwide. More than 400,000 people worldwide are newly diagnosed every year. Within 2 years after diagnosis, 80% of patients with muscle invasive bladder cancer without treatment die. The aggressive local surgical approach with a cystectomy is the therapy of choice. The median age of patients with de novo bladder cancer is 70 years. Thus bladder cancer is a cancer of the elderly. For demographical reasons, the number of eldery patients undergoing radical cystectomy will rise in the next few years. The type of urinary diversion is a major factor influencing perioperative morbidity and quality of life in these patients. Incontinent urinary diversions are preferentially used in daily practice. There are only a few contraindications for orthotopic neobladder; however, age alone is not a contraindication. Patient selection and a nerve sparing approach are crucial in men and women to achieve excellent functional results with orthotopic neobladder in elderly patients.

    The rapid advances in information technology and communication bandwidth have spawned an equally rapid development of clinical teleradiology. Current computer technology and communication capability allow easy transfer of diagnostic images, of any complexity, to any location in the world. This provides the opportunity to acquire swift primary and secondary diagnostic opinions from the remotest of locations, often at economically attractive rates, with the potential for easing the burden on hard-pressed departments of radiology. However, this comes at the potential cost of distancing the clinical radiologist from the patient, with consequent impact upon direct clinical care. As this technology advances across the world, it is vital that UK radiologists are familiar with the clinical implications, the medicolegal framework within which the field operates and the associated governance issues. This paper reviews current practice and discusses the associated risks

    Key factors in international development were discussed, using TransAlta Energy Corporation as an example. Trans-Alta is a company generating 4,500 MW of electricity from coal, hydro and natural gas. It has operating facilities in Canada, Argentina and New Zealand, including extensive coal mining interests in Canada. The climate for international opportunities in the energy field were judged to be very good in view of the projected requirement for some 900,000 MW of new power generation in different parts of the world by the year 2003. The five key factors identified for international power development were: (1) using core skills to add value, (2) have a long-term focus, (3) focus on specific countries and selected regions, (4) develop strong relationships with local partners, and (5) develop appropriate projects. 2 figs

    Scrutinized from the perspective of time, the giants in the history of crystallography more than once missed a nearly obvious chance to make another great discovery, or went in the wrong direction. This review analyzes such missed opportunities focusing on macromolecular crystallographers (using Perutz, Pauling, Franklin as examples), although cases of particular historical (Kepler), methodological (Laue, Patterson) or structural (Pauling, Ramachandran) relevance are also described. Linus Pauling, in particular, is presented several times in different circumstances, as a man of vision, oversight, or even blindness. His example underscores the simple truth that also in science incessant creativity is inevitably connected with some probability of fault. Published 2014.

    Full Text Available This article is targeted to faculty teaching race and ethnicity, racism, diversity, and multicultural courses. Many students equate race with skin color. The premise of this article is that to teach students about the social construction of race, teachers must first know enough science to teach students that race is not biological. This article examines the biology of race by showing how advances in DNA sequencing led to genetics research that supports arguments that race is not biological. DNA comparisons show that all human populations living today are one species that came from Africa. The article explains the migration of humans out of Africa about 60,000 years ago and how they populated Australia, then Asia, Europe, and the Americas. The article shows how recent research maps the timing of the migration and admixture of specific population groups into Europe and India. The article shows how a mutation in one nucleotide can result in a trait like blue eyes, or Hemoglobin S (which confers resistance to malaria, which can be subject to evolution through natural selection. DNA comparisons show how natural selection shaped the genetics of human skin color to adapt to less UV light in the northern latitudes of Europe and Asia. The article shows that there is no relation between skin color or other “racial” characteristics and complex traits like intelligence. The science in this article will help teachers explain that as race is not biological, race is socially constructed and culturally enacted.

    2015-05-06

    Recent metagenomic studies of environments, such as marine and soil, have significantly enhanced our understanding of the diverse microbial communities living in these habitats and their essential roles in sustaining vast ecosystems. The increase in the number of publications related to soil and marine metagenomics is in sharp contrast to those of air, yet airborne microbes are thought to have significant impacts on many aspects of our lives from their potential roles in atmospheric events such as cloud formation, precipitation, and atmospheric chemistry to their major impact on human health. In this review, we will discuss the current progress in airborne metagenomics, with a special focus on exploring the challenges and opportunities of undertaking such studies. The main challenges of conducting metagenomic studies of airborne microbes are as follows: 1) Low density of microorganisms in the air, 2) efficient retrieval of microorganisms from the air, 3) variability in airborne microbial community composition, 4) the lack of standardized protocols and methodologies, and 5) DNA sequencing and bioinformatics-related challenges. Overcoming these challenges could provide the groundwork for comprehensive analysis of airborne microbes and their potential impact on the atmosphere, global climate, and our health. Metagenomic studies offer a unique opportunity to examine viral and bacterial diversity in the air and monitor their spread locally or across the globe, including threats from pathogenic microorganisms. Airborne metagenomic studies could also lead to discoveries of novel genes and metabolic pathways relevant to meteorological and industrial applications, environmental bioremediation, and biogeochemical cycles.

    2017-01-01

    Full Text Available This paper studies the optimal mortgage choice of an investor in a simple bond market with a stochastic interest rate and access to term life insurance. The study is based on advances in stochastic control theory, which provides analytical solutions to portfolio problems with a stochastic interest rate. We derive the optimal portfolio of a mortgagor in a simple framework and formulate stylized versions of mortgage products offered in the market today. This allows us to analyze the optimal investment strategy in terms of optimal mortgage choice. We conclude that certain extreme investors optimally choose either a traditional fixed rate mortgage or an adjustable rate mortgage, while investors with moderate risk aversion and income prefer a mix of the two. By matching specific investor characteristics to existing mortgage products, our study provides a better understanding of the complex and yet restricted mortgage choice faced by many household investors. In addition, the simple analytical framework enables a detailed analysis of how changes to market, income and preference parameters affect the optimal mortgage choice.

    2013-04-01

    Full Text Available This paper addresses the significance of traveller information sources including mono-modal and multimodal websites for travel decisions. The research follows a decision paradigm developed earlier, involving an information acquisition process for travel choices, and identifies the abstract characteristics of new information sources that deserve further investigation (e.g. by incorporating these in models and studying their significance in model estimation. A Stated Preference experiment is developed and the utility functions are formulated by expanding the travellers' choice set to include different combinations of sources of information. In order to study the underlying choice mechanisms, the resulting variables are examined in models based on different behavioural strategies, including utility maximisation and minimising the regret associated with the foregone alternatives. This research confirmed that RRM (Random Regret Minimisation Theory can fruitfully be used and can provide important insights for behavioural studies. The study also analyses the properties of travel planning websites and establishes a link between travel choices and the content, provenance, design, presence of advertisements, and presentation of information. The results indicate that travellers give particular credence to governmentowned sources and put more importance on their own previous experiences than on any other single source of information. Information from multimodal websites is more influential than that on train-only websites. This in turn is more influential than information from friends, while information from coachonly websites is the least influential. A website with less search time, specific information on users' own criteria, and real time information is regarded as most attractive

  17. Using strategic foresight to assess conservation opportunity.

    Science.gov (United States)

    Cook, Carly N; Wintle, Bonnie C; Aldrich, Stephen C; Wintle, Brendan A

    2014-12-01

    The nature of conservation challenges can foster a reactive, rather than proactive approach to decision making. Failure to anticipate problems before they escalate results in the need for more costly and time-consuming solutions. Proactive conservation requires forward-looking approaches to decision making that consider possible futures without being overly constrained by the past. Strategic foresight provides a structured process for considering the most desirable future and for mapping the most efficient and effective approaches to promoting that future with tools that facilitate creative thinking. The process involves 6 steps: setting the scope, collecting inputs, analyzing signals, interpreting the information, determining how to act, and implementing the outcomes. Strategic foresight is ideal for seeking, recognizing, and realizing conservation opportunities because it explicitly encourages a broad-minded, forward-looking perspective on an issue. Despite its potential value, the foresight process is rarely used to address conservation issues, and previous attempts have generally failed to influence policy. We present the strategic foresight process as it can be used for proactive conservation planning, describing some of the key tools in the foresight tool kit and how they can be used to identify and exploit different types of conservation opportunities. Scanning is an important tool for collecting and organizing diverse streams of information and can be used to recognize new opportunities and those that could be created. Scenario planning explores how current trends, drivers of change, and key uncertainties might influence the future and can be used to identify barriers to opportunities. Backcasting is used to map out a path to a goal and can determine how to remove barriers to opportunities. We highlight how the foresight process was used to identify conservation opportunities during the development of a strategic plan to address climate change in New York

  3. Irrational choice behavior in human and nonhuman primates.

    Choice behavior in humans has motivated a large body of research with a focus on whether decisions can be considered to be rational. In general, humans prefer having choice, as do a number of other species that have been tested, even though having increased choice does not necessarily yield a positive outcome. Humans have been found to choose an option more often only because the opportunity to select it was diminishing, an example of a deviation from economic rationality. Here we extend this paradigm to nonhuman primates in an effort to understand the mechanisms underlying this finding. In this study, we presented two groups of laboratory monkeys, capuchins (Cebus apella) and rhesus macaques (Macaca mulatta), as well as human subjects, with a computerized task in which subjects were presented with two differently colored icons. When the subject selected an icon, differing numbers of food pellets were dispensed (or points were assigned), making each icon correspond to a certain level of risk (one icon yielded 1 or 4 pellets/points and the other yielded 2 or 3). Initially, both options remained constantly available and we established choice preference scores for each subject. Then, we assessed preference patterns once the options were not continuously available. Specifically, choosing one icon would cause the other to shrink in size on the screen and eventually disappear if never selected. Selecting it would restore it to its full size. As predicted, humans shifted their risk preferences in the diminishing options phase, choosing to click on both icons more equally in order to keep both options available. At the group level, capuchin monkeys showed this pattern as well, but there was a great deal of individual variability in both capuchins and macaques. The present work suggests that there is some degree of continuity between human and nonhuman primates in the desire to have choice simply for the sake of having choice.

    This paper discusses choice in mental health supported housing, providing results from a longitudinal study of two models of supported housing (a higher support and a lower support model). The progress of 27 tenants at the two sites was tracked on measures of satisfaction with housing, social support satisfaction, mental health, physical health, and mastery over the course of one year. Measurements were taken at baseline, 6 months, and 12 months. Although there were trends toward positive changes at both sites, with the Bonferroni adjustment, only positive within group changes in perceptions of physical health between baseline and 12 months at the higher support site endured. There were no significant differences in changes between the two sites. We conclude that there appears to be some support for the positive effects of choice in mental health supported housing. Further research in this area will require flexible programming and funding that create opportunities for true partnerships with consumer-survivors.

    Full Text Available This article considers the design and production of spectacles in Britain following the introduction of standardised frame styles under the National Health Service. NHS spectacles were provided as a functional, durable medical appliance to be delivered cost-effectively and there was no explicit concern for fashion or the patient experience. The actions of the government and professional bodies greatly affected the trade in eyewear and thus restricted opportunities for innovative design and consumer choice. Within the range of state regulation frames there was no active concern for ‘design’ in terms of appearance and it was only through the purchase of private frames that significant choice and variety in eyewear could be attained. The scope for the public to select a more fashionable frame whilst receiving an element of state aid was through the purchase of NHS hybrid private frames.

    To evaluate environmental obesogenic-related factors, such as physical activity in neighborhoods and schools, nutritional behavior, and intervention programs. Critical analysis of literature with personal point of view from infant obesity experts and political advisors for public intervention. Although obesity is a public health problem affecting several age groups, it is among children and adolescents that it plays a more important role, due to treatment complexity, high likelihood of persistence into adulthood, and association with other non-transmissible diseases while still in early age. Environment is a main component of the genesis and outcomes in the near future or long term. Modification of intake with high-density food, meal skipping, and high intake of saturated fat, sugar, and salt, associated to high levels of sedentarism are main causes of obesity. Intervention opportunities are related to modifications in political, environmental, and individual settings. School and physical activities in the educational environment are intertwined with nutrition intervention in continuous education. A critical review of some different scenarios in Latin American countries is presented. Copyright © 2016 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda. All rights reserved.

    The vast majority of observing time on the Space Infrared Telescope Facility (SIRTF), to be launched next year, will be available to the broad science community. A unique and innovative component of this community observing time is the Legacy Science Program, enabling investigators to conduct large and coherent science programs early in the mission, with data entering the public domain immediately upon processing at the SIRTF Science Center (SSC). The Legacy Science Call for Proposals (CP) is now open, and proposals are due on September 15, 2000. The first General Observer CP will be issued in late 2001, with proposals due four months after launch. Subsequent CPs will be issued by the SSC on an approximately annual basis. Archival research with SIRTF data will be possible within 6 months of launch, utilizing data from the First-Look Survey and from early Legacy Science observations. The author will provide an overview of the research opportunities available with SIRTF, the nominal schedule of CPs, and the anticipated plans for data analysis funding. Proposal submission procedures, and an introduction to planning and proposing tools and resources, will be provided. A description of the SIRTF observing modes and their corresponding SSC pipeline data products will also be presented.

  9. [Choice of bariatric and metabolic surgical procedures].

    Bariatric and metabolic surgery has become the clinical hot topic of the treatment of metabolic syndromes including obesity and diabetes mellitus, but how to choose the appropriate surgical procedure remains the difficult problem in clinical practice. Clinical guidelines of American Society for Metabolic and Bariatric Surgery(ASMBS)(version 2013) introduced the procedures of bariatric and metabolic surgery mainly including biliopancreatic diversion with duodenal switch(BPD-DS), laparoscopic adjustable gastric banding (LAGB), laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy(LSG). To choose the appropriate bariatric and metabolic procedure, the surgeons should firstly understand the indications and the contraindications of each procedure. Procedure choice should also consider personal condition (body mass index, comorbidities and severity of diabetes), family and socioeconomic status (postoperative follow-up attendance, understanding of potential surgical risk of gastrectomy and patient's will), family and disease history (patients with high risk of gastric cancer should avoid LRYGB; patients with gastroesophageal reflux disease should avoid LSG) and associated personal factors of surgeons. With the practice of bariatric and metabolic surgery, the defects, especially long-term complications, of different procedures were found. For example, LRYGB resulted in higher incidence of postoperative anemia and marginal ulcer, high risk of gastric cancer as well as the requirement of vitamin supplementation and regular follow-up. Though LSG has lower surgical risk, its efficacy of diabetes mellitus remission and long-term weight loss are inferior to the LRYGB. These results pose challenges to the surgeons to balance the benefits and risks of the bariatric procedures. A lot of factors can affect the choice of bariatric and metabolic procedure. Surgeons should choose the procedure according to patient's condition with the consideration of the

    There is a projected shortage of kidney specialists, and retention of trainees in nephrology is important. Determining factors that result in choosing a nephrology career could inform future strategies to attract nephrology fellows. An anonymous, internet-based survey was sent to members of the American Society of Nephrology in June 2009. Respondents answered questions about demographics, training background, and career choices. Of the 3399 members, 913 (23%) returned the survey. Mean age was 51.1 ± 10.5 years, and 46.1% were academic nephrologists. In addition, 38.4% of respondents graduated between 2000 and 2009. Interest in nephrology began early in training, with the intellectual aspects of nephrology, early mentoring, and participation in nephrology electives named as the most common reasons in choosing nephrology. Academic nephrologists were more likely to have participated in research in medical school, have a master's degree or PhD, and successfully obtained research funding during training. Academic debt was higher among nonacademic nephrologists. Research opportunities and intellectual stimulation were the main factors for academic nephrologists when choosing their first postfellowship positions, whereas geographic location and work-life balance were foremost for nonacademic nephrologists. These findings highlight the importance of exposing medical students and residents to nephrology early in their careers through involvement in research, electives, and positive mentoring. Further work is needed to develop and implement effective strategies, including increasing early exposure to nephrology in preclinical and clinical years, as well as encouraging participation in research, in order to attract future nephrology trainees.

The main focus of this study was to determine the logistics opportunity costs of using road transport within a mining firm. A case study approach was followed, as the investigation aimed to analyse a complex problem experienced by one company and present it in an easily understandable format. From the results of this study, it was apparent that the logistics opportunity costs associated with the mode of transport was substantial. This highlighted the need for firms to revise their choice of transport mode on a regular basis, as it has a major impact not only on their transportation costs, but also on their inventory holding and carbon emissions. The results also have implications for South Africa’s only freight railway, Transnet Freight Rail, which should not only focus on expanding its existing capacity, but also on improving its customer service delivery whilst containing tariff increases.

  14. MHC-based patterns of social and extra-pair mate choice in the Seychelles warbler

    2005-01-01

    The existence and nature of indirect genetic benefits to mate choice remain contentious. Major histocompatibility complex (MHC) genes, which play a vital role in determining pathogen resistance in vertebrates, may be the link between mate choice and the genetic inheritance of vigour in offspring. Studies have shown that MHC-dependent mate choice can occur in mammal and fish species, but little work has focused on the role of the MHC in birds. We tested for MHC-dependent mating patterns in the Seychelles warbler (Acrocephalus sechellensis). There was no influence of MHC class I exon 3 variation on the choice of social mate. However, females were more likely to obtain extra-pair paternity (EPP) when their social mate had low MHC diversity, and the MHC diversity of the extra-pair male was significantly higher than that of the cuckolded male. There was no evidence that females were mating disassortatively, or that they preferred males with an intermediate number of MHC bands. Overall, the results are consistent with the ‘good genes’ rather than the ‘genetic compatibility’ hypothesis. As female choice will result in offspring of higher MHC diversity, MHC-dependent EPP may provide indirect benefits in the Seychelles warbler if survival is positively linked to MHC diversity.

    Cultural diversity and its impact on mental health has become an increasingly important issue in a globalised world where the interactions between cultures continue to grow exponentially. This paper presents critical areas in which culture impacts on mental health, such as how health and illness are perceived, coping styles, treatment-seeking patterns, impacts of history, racism, bias and stereotyping, gender, family, stigma and discrimination. While cultural differences provide a number of challenges to mental health policy and practice they also provide a number of opportunities to work in unique and effective ways towards positive mental health. Ethno-specific approaches to mental health that incorporate traditional and community-based systems can provide new avenues for working with culturally diverse populations. © The Royal Australian and New Zealand College of Psychiatrists 2015.

  3. Combining food type(s) and food quantity choice in a new food choice paradigm based on vice-virtue bundles.

    2016-08-01

    Given the prevalence and rising rates of obesity in many countries, including the United States, much food decision-making research ultimately aims at understanding how consumers can make healthier choices. The two predominant choice paradigms used in food decision-making research ask consumers to choose (a) between a "vice" (or unhealthy food) and a "virtue" (or healthy food) or (b) among varying portion sizes of "vice." We propose a new food choice paradigm that encourages consumers to jointly consider both food type(s) choice and food portion size at each decision point. The purpose of this paradigm is two-fold. First, it aims to allow examination of more comprehensive eating behavior (e.g., to examine the overall composition of a plate of food rather than choice of a single food). Second, it aims to shift consumers towards including large proportions of virtues and smaller proportions of vice in their overall consumption portfolios. For this paradigm, we draw upon a recently introduced food product innovation called "vice-virtue bundles" (Liu et al., 2015) that illustrates the basis of this new food choice paradigm, in which food type(s) and portion decisions are made simultaneously. Accordingly, we first discuss relevant findings on vice-virtue bundles as well as the differences between simultaneous and sequential choice of multiple products. Second, we examine the benefits for managing and controlling one's consumption that are provided by vice-virtue bundles and this joint food choice paradigm more generally. Third and finally, we point out opportunities for future research by discussing (a) multiple factors that influence food choices, (b) decision processes affected by food choice paradigms, and (c) issues of generalizability related to the presence of vice-virtue bundles.

    2014-12-01

    Climate and environmental decisions require science that couples human and natural systems to quantify or articulate the observed physical, natural, and societal changes or likely consequences of different decision options. Despite the need for such policy-relevant research, multidisciplinary collaborations can be wrought with challenges of data integration, model interoperability, and communication across disciplinary divides. In this talk, I will present several examples where I have collaborated with colleagues from the physical, natural, and social sciences to develop novel, actionable science to inform decision-making. Specifically, I will discuss a cost analysis of water and sediment diversions to optimize land building in the Mississippi River delta (winner of American Geophysical Union Water Resources Research Editor's Choice Award 2014) and the development of a National Climate Indicator System that uses knowledge across the physical, natural, and social sciences to establish an end-to-end indicator system of climate changes, impacts, vulnerabilities, and responses. The latter project is in the process of moving from research to operations, an additional challenge and opportunity, as we work with the U.S. Global Change Research Program and their affiliated Federal agencies to establish it beyond the research prototype. Using these examples, I will provide some lessons learned that would have general applicability to socio-environmental research collaborations and integration of data, models, and information systems to support climate and environmental decision-making.

    Frank, David

    2014-03-01

    This paper critically discusses two areas of Sahotra Sarkar's recent work in environmental philosophy: biodiversity and conservation biology and roles for decision theory in incorporating values explicitly in the environmental policy process. I argue that Sarkar's emphasis on the practices of conservation biologists, and especially the role of social and cultural values in the choice of biodiversity constituents, restricts his conception of biodiversity to particular practical conservation contexts. I argue that life scientists have many reasons to measure many types of diversity, and that biodiversity metrics could be value-free. I argue that Sarkar's emphasis on the limitations of normative decision theory is in tension with his statement that decision theory can "put science and ethics together." I also challenge his claim that multi-criteria decision tools lacking axiomatic foundations in preference and utility theory are "without a rational basis," by presenting a case of a simple "outranking" multi-criteria decision rule that can violate a basic normative requirement of preferences (transitivity) and ask whether there may nevertheless be contexts in which such a procedure might assist decision makers.

  13. Cocaine choice procedures in animals, humans, and treatment-seekers: Can we bridge the divide?

    Science.gov (United States)

    Moeller, Scott J.; Stoops, William W.

    2015-01-01

    Individuals with cocaine use disorder chronically self-administer cocaine to the detriment of other rewarding activities, a phenomenon best modeled in laboratory drug-choice procedures. These procedures can evaluate the reinforcing effects of drugs versus comparably valuable alternatives under multiple behavioral arrangements and schedules of reinforcement. However, assessing drug-choice in treatment-seeking or abstaining humans poses unique challenges: for ethical reasons, these populations typically cannot receive active drugs during research studies. Researchers have thus needed to rely on alternative approaches that approximate drug-choice behavior or assess more general forms of decision-making, but whether these alternatives have relevance to real-world drug-taking that can inform clinical trials is not well-understood. In this mini-review, we (A) summarize several important modulatory variables that influence cocaine choice in nonhuman animals and non-treatment seeking humans; (B) discuss some of the ethical considerations that could arise if treatment-seekers are enrolled in drug-choice studies; (C) consider the efficacy of alternative procedures, including non-drug-related decision-making and ‘simulated’ drug-choice (a choice is made, but no drug is administered) to approximate drug choice; and (D) suggest opportunities for new translational work to bridge the current divide between preclinical and clinical research.

    This commentary explores theoretical alternatives for viewing the problem identified by Volny Fages and Virginie Albe in their article entitled Social issues in nanoscience and nanotechnology Master's degrees: The socio-political stakes of curricular choices. An approach to social research is suggested that would render visible the associations maintaining the states of affairs depicted by Fages and Albe. In their research, Fages and Albe identified conceptions of the relationship between scientific endeavour and social concerns to be at the root of "choices" made by coordinators of Masters programs in nano science and technology in universities selected for their study. Albe and Fages, insiders in the sense that they take responsibility for a particular program within one such course, convey their belief that, "future scientists need to identify, accept and take on board the social responsibilities linked to their own practice of science, and to work collectively for a more democratic division of power regarding socio-technical choices". However, many of the Master's programs reviewed in their research were reported as providing limited opportunities for their students to critically engage with social aspects of scientific work. This commentary questions the notion of "choices" used in their research and proposes Actor-Network Theory as a theoretical framework open to the existence of various human and non-human agencies at work when a "choice" is made. The aim of the commentary is to further Fages and Albe's agenda by calling for understanding and ultimately a reassembling of the state of affairs in a way that would be acceptable to those invested.

  15. MOTIVES FOR FOOD CHOICE AMONG SERBIAN CONSUMERS

    People's motives for food choice depend on a number of very complex economic, social and individual factors. A Food Choice Questionnaire (FCQ), an instrument that measures the importance of factors underlying food choice, was used to reveal the Serbian consumers' food choice motives by survey of 450 respondents of different age groups. A confirmatory factor analysis was conducted on the motive items, using 11 factors. Previous research shows that the nutrition in Serbia is not balanced enough,...

    With the availability of more healthcare courses and an increased intake of nursing students, education institutions are facing challenges to attract school leavers to enter nursing courses. The comparison of career choice influences and perception of nursing among healthcare students can provide information for recruitment strategies. An instrument to compare the influences of healthcare career choice is lacking. The purpose of this study is to develop and evaluate the psychometric properties of an instrument to compare the influences of healthcare career choice with perceptions of nursing as a career choice. The study was conducted in two phases. In phase one, two sets of scales with parallel items that measure the influences of healthcare career choice and perceptions of nursing as a career choice were developed through an earlier qualitative study, literature review, and expert validation. Phase two involved testing the construct validity, concurrent validity and reliability with a convenience sample of 283 first year healthcare students who were recruited at two education institutions in Singapore. An exploratory factor analysis revealed 35-parallel items in a six-factor solution (personal interest, prior healthcare exposure, self-efficacy, perceived nature of work, job prospects, and social influences) that explained 59 and 64% of the variance for healthcare career choice and nursing as a career choice respectively. A high correlation (r = 0.76, p career choice and 0.94 for nursing as a career choice. The test-retest reliability was acceptable with an Intraclass Correlation Coefficient of 0.63 for healthcare career choice and 0.60 for nursing as a career choice. The instrument provides opportunities for understanding the differences between influences of healthcare career choice and perceptions of nursing as a career choice. This comparative understanding of career choice influences can guide educator and policy-makers on nursing recruitment.

  17. Discrete choice modeling of season choice for Minnesota turkey hunters

    2018-01-01

    Recreational turkey hunting exemplifies the interdisciplinary nature of modern wildlife management. Turkey populations in Minnesota have reached social or biological carrying capacities in many areas, and changes to turkey hunting regulations have been proposed by stakeholders and wildlife managers. This study employed discrete stated choice modeling to enhance understanding of turkey hunter preferences about regulatory alternatives. We distributed mail surveys to 2,500 resident turkey hunters. Results suggest that, compared to season structure and lotteries, additional permits and level of potential interference from other hunters most influenced hunter preferences for regulatory alternatives. Low hunter interference was preferred to moderate or high interference. A second permit issued only to unsuccessful hunters was preferred to no second permit or permits for all hunters. Results suggest that utility is not strictly defined by harvest or an individual's material gain but can involve preference for other outcomes that on the surface do not materially benefit an individual. Discrete stated choice modeling offers wildlife managers an effective way to assess constituent preferences related to new regulations before implementing them. 

  18. Hibernia production opportunities: A report on business and employment opportunities within the production phase of Hibernia

    International Nuclear Information System (INIS)

    1994-07-01

    The offshore industry in Newfoundland is evolving into a new phase as construction of the Hibernia offshore platform continues and plans are being developed for the operation of the facility to extract oil from deposits on the Grand Banks. A study was conducted to identify the business and employment opportunities available to Newfoundland firms and individuals during Hibernia's production phase. To operate the platform, the Hibernia Management and Development Company (HMDC) and its contractors will employ ca 700-800 people directly. Average annual expenditures will be ca $400 million over the project life of 19 y. Ca 38% of these expenditures represent the operator's own costs, with the rest spent on downhole services, modifications and repairs, logistics and transportation, replacement equipment and materials, and routine maintenance. It is clearly stated that in formulating strategies to pursue production phase opportunities, companies must understand the greenfield characteristics of the Hibernia oil field and the implications that has on the operator's philosophy to procuring goods and services. Paramount to the discussion on procurement is the operator's choice of contracting out and performing services in-house. A number of approaches used by North Sea operators to procure goods and services are reviewed, and a trend is noted toward partnering agreements which are defined as multipurpose, long-term contractual relationships. HMDC is considering entering such agreements. HMDC's employment policies are outlined and business opportunities are described in alphabetical order by sector, giving a description of the opportunity, contracting strategy, and a list of typical companies involved in the sector. 2 figs., 7 tabs

    Five consumer vehicle choice models that give projections of future sales shares of light-duty vehicles were compared by running each model using the same inputs, where possible, for two scenarios. The five models compared — LVCFlex, MA3T, LAVE-Trans, ParaChoice, and ADOPT — have been used in support of the Energy Efficiency and Renewable Energy (EERE) Vehicle Technologies Office in analyses of future light-duty vehicle markets under different assumptions about future vehicle technologies and market conditions. The models give projections of sales shares by powertrain technology. Projections made using common, but not identical, inputs showed qualitative agreement, with the exception of ADOPT. ADOPT estimated somewhat lower advanced vehicle shares, mostly composed of hybrid electric vehicles. Other models projected large shares of multiple advanced vehicle powertrains. Projections of models differed in significant ways, including how different technologies penetrated cars and light trucks. Since the models are constructed differently and take different inputs, not all inputs were identical, but were the same or very similar where possible. Projections by all models were in close agreement only in the first few years. Although the projections from LVCFlex, MA3T, LAVE-Trans, and ParaChoice were in qualitative agreement, there were significant differences in sales shares given by the different models for individual powertrain types, particularly in later years (2030 and later). For example, projected sales shares of conventional spark-ignition vehicles in 2030 for a given scenario ranged from 35% to 74%. Reasons for such differences are discussed, recognizing that these models were not developed to give quantitatively accurate predictions of future sales shares, but to represent vehicles markets realistically and capture the connections between sales and important influences. Model features were also compared at a high level, and suggestions for further comparison

The site can be found at www.asset.org.uk and it will be run by the Association for Schools' Science, Engineering and Technology (ASSET). The latest round of Foresight began in April and panels are taking a look at the aging population, crime prevention, built environment and transport, aerospace and systems, energy and the natural environment, information, communications and media, materials and sustainable development, amongst other topics. Information about Foresight activities and events can be obtained from the Office of Science and Technology or the Foresight Knowledge pool at www.foresight.gov.uk. The pool will act as a unique and freely accessible electronic library of views and information about the future that young people will be able to draw on for assistance and reference material. Futher assistance for students will also be on offer from museums and art galleries from now on, thanks to additional funding which has been made available over the next three years. Forty museums and galleries will share up to #2.5m for projects intended to improve students' literacy, numeracy and science skills as well as their understanding of history and art. Examples of the imaginative projects which have been put forward include use of the large collection of steam engines at the Museum of Science and Industry in Manchester to assist boys' science and literacy skills. The Museum of London will be working with over 2000 schools in the South East to provide materials for the schools' own mini-museums on the Romans

    We show how portfolio choice can be modeled in continuous time with transitory and persistent transaction costs, multiple assets, multiple signals predicting returns, and general signal dynamics. The objective function is derived from the limit of discrete-time models with endogenous transaction...... costs due to optimal dealer behavior. We solve the model explicitly and the intuitive solution is also the limit of the solutions of the corresponding discrete-time models. We show how the optimal high-frequency trading strategy depends on the nature of the trading costs, which in turn depend on dealers...

  11. The Paradox of Equal Opportunities

    Directory of Open Access Journals (Sweden)

    Mitja Sardoč

    2014-06-01

    Full Text Available The basic assumption of the idea of equal opportunities is based on the assertion that all individuals competing for an advantaged social position should have equal opportunities, i.e., that each and every one of them should have fair opportunities to achieve a particular goal. Despite the fact that equal opportunities is one of the basic mechanisms for a just distribution of advantageous social positions, the idea of fair equality of opportunity remains divided between different competing political projects, e.g., egalitarian liberalism, libertarian political theory, multiculturalism, etc. This paper examines two basic dimensions of equal opportunities to which existing conceptions fail to offer a unanimous answer, i.e., a the issue of fairness and b the issue of the currency of fairness. The concluding part of this paper presents two basic paradoxes that determine both the direction of the discussion as well as the possible solutions to the achievement of fair equal opportunities as part of any process for competing for advantageous social positions.

    On 28 November 2000, the European Commission adopted a Green Paper on a strategy for the security of energy supply. A consultation and debate will follow and interested parties have the right to submit comments relating to issues within the document. When the debate is brought to a close, a White Paper will be issued by the European Commission, which will then be sent to the European Parliament and Council. The White Paper will represent an official proposal reflecting all changes to the Green Paper already issued. The European Parliament will then adopt an opinion on the White Paper, which will then be communicated to the European Commission who in turn will adopt a draft directive or legislation. It will again be submitted to the European Parliament and Council for approval. Let us make no mistake. What might appear as a cumbersome process far from the grassroots preoccupations, will in fact affect all European citizens in the end. So in this democratic consultation, it is crucial that policies be established in an informed, educated manner. It is therefore the duty of the industry to communicate in a transparent fashion about its benefits and drawbacks so that in the end, the best decisions will be based on facts and not on fear

    2015-05-06

    Recent metagenomic studies of environments, such as marine and soil, have significantly enhanced our understanding of the diverse microbial communities living in these habitats and their essential roles in sustaining vast ecosystems. The increase in the number of publications related to soil and marine metagenomics is in sharp contrast to those of air, yet airborne microbes are thought to have significant impacts on many aspects of our lives from their potential roles in atmospheric events such as cloud formation, precipitation, and atmospheric chemistry to their major impact on human health. In this review, we will discuss the current progress in airborne metagenomics, with a special focus on exploring the challenges and opportunities of undertaking such studies. The main challenges of conducting metagenomic studies of airborne microbes are as follows: 1) Low density of microorganisms in the air, 2) efficient retrieval of microorganisms from the air, 3) variability in airborne microbial community composition, 4) the lack of standardized protocols and methodologies, and 5) DNA sequencing and bioinformatics-related challenges. Overcoming these challenges could provide the groundwork for comprehensive analysis of airborne microbes and their potential impact on the atmosphere, global climate, and our health. Metagenomic studies offer a unique opportunity to examine viral and bacterial diversity in the air and monitor their spread locally or across the globe, including threats from pathogenic microorganisms. Airborne metagenomic studies could also lead to discoveries of novel genes and metabolic pathways relevant to meteorological and industrial applications, environmental bioremediation, and biogeochemical cycles. © The Author(s) 2015.

    Specialty choices of medical undergraduates are important in planning educational programs and human resources for health-care delivery. The aim of this study was to investigate the specialty preferences of medical undergraduates and determine the factors that influenced their specialty choices. This was a cross-sectional questionnaire-based survey carried out among final year medical undergraduates of University of Nigeria Enugu Campus, Enugu Nigeria. A self-administered questionnaire was used for data collection from the participants. Sociodemographic characteristics, decision to specialize, the timing of the decision, specialty choices and factors influencing these choices were evaluated. Chi-squared test and unpaired t-test were used to analyze the observations. Surgery and surgical specialties 79 (52%) were the most preferred specialties among the students. This was followed by obstetrics and gynecology 22 (14.5%) and public health 16 (10.5%). Personal interest in a specialty, personal abilities/competence, and career prospects were the most influential determinants of specialty choices. The career choices of male students were preferentially influenced by family/societal expectations (P = 0.03) and diversity of patients (P = 0.01). Low work hours significantly (P = 0.04) influenced the career choices of female students. Surgical specialties, obstetrics and gynecology, and public health were the most preferred specialties among our participants. The most important determinants of specialty choices were personal interest, personal abilities, and career prospects.

    As part of a larger study on women's views of the childbirth experience, this study was focused on women's choice of childbirth setting. Sixty-one Lamaze-prepared, married multigravidae between the ages of 21 and 37 and experiencing a normal pregnancy were interviewed twice: at 36-38 weeks gestation in their homes and during their postpartum stay in the hospital. Data were collected using (a) two semistructured interview guides consisting of open-ended questions about choosing a caregiver and the place of birth and about describing the actual childbirth experience, (b) a self-administered sociodemographic questionnaire, and (c) an obstetrical and infant data form. The tape-recorded interviews were transcribed verbatim. Qualitative data analysis was focused on reasons for choosing a hospital and a physician, reasons for choosing or not choosing a birthing room, and the outcomes of the decisions. An understanding of women's childbirth needs as reflected in their choices can suggest areas where flexibility might be built into maternity care programs.

    Objective: Women of lower educational attainment have less balanced and varied diets than women of higher educational attainment. The diets of women are vital to the long-term health of their offspring. The present study aimed to identify factors that influence the food choices of women with lower...... that they lacked control over food choices for themselves and their families. Partners and children exerted a high degree of control over which foods were bought and prepared. Women's perceptions of the cost of healthy food, the need to avoid waste, being trapped at home surrounded by opportunities to snack......, and having limited skill and experience with food, all contributed to their sense they lacked control over their own and their family's food choices. Conclusions: An intervention to improve the food choices of women with lower educational attainment needs to increase their sense of control over their diet...

    Research findings The present study observed and coded instruction in 65 preschool classrooms to examine (a) overall amounts and (b) types of mathematics and science learning opportunities experienced by preschool children as well as (c) the extent to which these opportunities were associated with classroom and program characteristics. Results indicated that children were afforded an average of 24 and 26 minutes of mathematics and science learning opportunities, respectively, corresponding to spending approximately 25% of total instructional time in each domain. Considerable variability existed, however, in the amounts and types of mathematics and science opportunities provided to children in their classrooms; to some extent, this variability was associated with teachers’ years of experience, teachers’ levels of education, and the socioeconomic status of children served in the program. Practice/policy Although results suggest greater integration of mathematics and science in preschool classrooms than previously established, there was considerable diversity in the amounts and types of learning opportunities provided in preschool classrooms. Affording mathematics and science experiences to all preschool children, as outlined in professional and state standards, may require additional professional development aimed at increasing preschool teachers’ understanding and implementation of learning opportunities in these two domains in their classrooms.

    Choice is a behavioral act that has a variety of well-documented motivational consequences-it fosters independence by allowing people to simultaneously express themselves and influence the environment. Given the link between independence and analytic thinking, the current research tested whether choice also leads people to think in a more analytic rather than holistic manner. Four experiments demonstrate that making choices, recalling choices, and viewing others make choices leads people to think more analytically, as indicated by their attitudes, perceptual judgments, categorization, and patterns of attention allocation. People who made choices scored higher on a subjective self-report measure of analytic cognition compared to whose did not make a choice (pilot study). Using an objective task-based measure, people who recalled choices rather than actions were less influenced by changes in the background when making judgments about focal objects (Experiment 1). People who thought of others' behaviors as choices rather than actions were more likely to group objects based on categories rather than relationships (Experiment 2). People who recalled choices rather than actions subsequently allocated more visual attention to focal objects in a scene (Experiment 3). Together, these experiments demonstrate that choice has important yet previously unexamined consequences for basic psychological processes such as attention and cognition.

    Full Text Available The growth of fitness centers in Indonesia has given a very good opportunity to the sports drink industry to grow. In general, a fitness center does not only provide services of sports facilities but also sell supplements and drinks to consumers for their exercises. The type of drinks highly in demand by consumers in the fitness center is sports drinks. The objective of this study was to identify the influences of brand positioning, brand image and perceived value on brand choices of sports drink products on the consumer fitness center. This study used a quantitative approach using a survey method to the customers of the fitness centers, and the data analysis method used was PLS (Partial Least Square. The results of the PLS analysis show that the perceived value, brand image and brand positioning have positive and significant influences on brand choice of drink sports drinks of the consumers of the fitness centers in Bogor.

  11. Generating route choice sets with operation information on metro networks

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available In recent years, the metro system has advanced into an efficient transport system and become the mainstay of urban passenger transport in many mega-cities. Passenger flow is the foundation of making and coordinating operation plans for the metro system, and therefore, a variety of studies were conducted on transit assignment models. Nevertheless route choice sets of passengers also play a paramount role in flow estimation and demand prediction. This paper first discusses the main route constraints of which the train schedule is the most important, that distinguish rail networks from road networks. Then, a two-step approach to generate route choice set in a metro network is proposed. Particularly, the improved approach introduces a route filtering with train operational information based on the conventional method. An initial numerical test shows that the proposed approach gives more reasonable route choice sets for scheduled metro networks, and, consequently, obtains more accurate results from passenger flow assignment. Recommendations for possible opportunities to apply this approach to metro operations are also provided, including its integration into a metro passenger flow assignment and simulation system in practice to help metro authorities provide more precise guidance information for passengers to travel.

  12. Cultures of choice: towards a sociology of choice as a cultural phenomenon.

    Science.gov (United States)

    Schwarz, Ori

    2017-09-07

    The article explores different ways to conceptualize the relationship between choice and culture. These two notions are often constructed as opposites: while sociologies of modernization (such as Giddens') portray a shift from cultural traditions to culturally disembedded choice, dispositional sociologies (such as Bourdieu's) uncover cultural determination as the hidden truth behind apparent choice. However, choice may be real and cultural simultaneously. Culture moulds choice not only by inculcating dispositions or shaping repertoires of alternatives, but also by offering culturally specific choice practices, ways of choosing embedded in meaning, normativity, and materiality; and by shaping attributions of choice in everyday life. By bringing together insights from rival schools, I portray an outline for a comparative cultural sociology of choice, and demonstrate its purchase while discussing the digitalization of choice; and cultural logics that shape choice attribution in ways opposing neoliberal trends. © London School of Economics and Political Science 2017.

    To ensure qualified health care professionals at public hospitals in the future, it is important to understand which factors attract health care professionals to certain positions. The aim of this study was to explore motives for choosing employment at either public or private hospitals in a group of Danish surgeons, as well as to examine if organizational characteristics had an effect on motivation. Eight qualitative interviews were conducted with surgeons from both public and private hospitals sampled using the snowball method. The interviews were based on a semi-structured interview guide and analyzed by means of phenomenological theory. Motivational factors such as personal influence on the job, the opportunity to provide the best possible patient care, challenging work tasks colleagues, and ideological reasons were emphasized by the surgeons as important reasons for their choice of employment. Motivational factors appeared to be strongly connected to the structure of the organization; especially the size of the organization was perceived to be essential. It is worth noting that salary, in contrast to the general belief, was considered a secondary benefit rather than a primary motivational factor for employment. The study revealed that motivational factors are multidimensional and rooted in organizational structure; i.e. organizational size rather than whether the organization is public or private is crucial. There is a need for further research on the topic, but it seems clear that future health care planning may benefit from taking into account the implications that large organizational structures have for the staff working within these organizations. not relevant. not relevant.

    American Physical Society (APS) has a wide range of education and diversity programs and activities, including programs that improve physics education, increase diversity, provide outreach to the public, and impact public policy. We present the latest programs spearheaded by the Committee on the Status of Women in Physics (CSWP), with highlights from other diversity and education efforts. The CSWP is working to increase the fraction of women in physics, understand and implement solutions for gender-specific issues, enhance professional development opportunities for women in physics, and remedy issues that impact gender inequality in physics. The Conferences for Undergraduate Women in Physics, Professional Skills Development Workshops, and our new Professional Skills program for students and postdocs are all working towards meeting these goals. The CSWP also has site visit and conversation visit programs, where department chairs request that the APS assess the climate for women in their departments or facilitate climate discussions. APS also has two significant programs to increase participation by underrepresented minorities (URM). The newest program, the APS National Mentoring Community, is working to provide mentoring to URM undergraduates, and the APS Bridge Program is an established effort that is dramatically increasing the number of URM PhDs in physics.

  4. Context-dependent preferences in starlings: linking ecology, foraging and choice.

    Directory of Open Access Journals (Sweden)

    Marco Vasconcelos

    Full Text Available Foraging animals typically encounter opportunities that they either pursue or skip, but occasionally meet several alternatives simultaneously. Behavioural ecologists predict preferences using absolute properties of each option, while decision theorists focus on relative evaluations at the time of choice. We use European starlings (Sturnus vulgaris to integrate ecological reasoning with decision models, linking and testing hypotheses for value acquisition and choice mechanism. We hypothesise that options' values depend jointly on absolute attributes, learning context, and subject's state. In simultaneous choices, preference could result either from comparing subjective values using deliberation time, or from processing each alternative independently, without relative comparisons. The combination of the value acquisition hypothesis and independent processing at choice time has been called the Sequential Choice Model. We test this model with options equated in absolute properties to exclude the possibility of preference being built at the time of choice. Starlings learned to obtain food by responding to four stimuli in two contexts. In context [AB], they encountered options A5 or B10 in random alternation; in context [CD], they met C10 or D20. Delay to food is denoted, in seconds, by the suffixes. Observed latency to respond (Li to each option alone (our measure of value ranked thus: LA≈LCchoice tests to predict sign and strength of preference in pairings. Starlings preferred A5 over C10 and C10 over B10. There was no detectable evaluation time, and preference magnitude was predictable from latency differentials. This implies that value reflects learning rather than choice context, that preferences are not constructed by relative judgements at the time of choice

  5. Political Preferences and Individual Choice: A Latin American's Countries Perspective

    Directory of Open Access Journals (Sweden)

    Regina Carla Madalozzo

    Full Text Available Abstract Analyzing the “left” and “right” political positions of individuals is challenging because personal attributes may influence political decisions without directly causing them. This issue may be even more pronounced in Latin America, where young democracies encounter the challenge of stabilizing political choices over time. This study contributes to the literature by analyzing the influence of personal attributes on political choices, focusing on the early 2000s, when the “left” turn occurred. The present study relies on the World Values Survey's fifth wave (2005-2008 to fulfil this objective. This dataset is composed of data that have been collected globally, and the questions are related to diverse subjects associated with the quality of life of individuals. From the available sample, we included all of the Latin American countries that participated in this wave: Argentina, Brazil, Chile, Colombia, Mexico, Peru, and Uruguay. In this study, the aim is to directly understand the impact of these individuals own attributes on their declared self-positioning about the political leaning. To this aim, an ordered logit model was used to analyse how each variable exerts influence on the political leaning of the respondents. Our results found that political cleavages depend on demographic factors, economic factors, and individual opinions in agreement with previous studies. Increased age, religious service attendance, and satisfaction with one's financial life increase the tendency of individuals for self-positioning to the right of the political spectrum. The possession of a university degree and residence in a large city increases the likelihood of individuals of self-identifying with a leftist political position. This study contributes to the literature by analysing the influence of personal attributes on political choices. Although this research represents an important step toward understanding political leanings in Latin

  6. Mostly empty words--what the discourse of "choice" in health care does.

    Science.gov (United States)

    Nordgren, Lars

    2010-01-01

    This paper has two purposes: one is to analyse how the policy of freedom of choice emerged and was formed in the Swedish health care discourse; the second is related to how free choice influences the discourse in health care and how subjects are formed within the field, i.e. what the language of choice in health care does. The research strategy is inspired by a combined theoretical framework borrowed from Michel Foucault's concepts of "discursive formation" and "subjectivization" completed with Judith Butler's concept of performativity. The language of "freedom of choice" calls to mind the rhetoric of promises, i.e. that the patient should be free and responsible, in his or her relation to health care. Since patients seem to be insufficiently informed and supported about the actual benefits of possibilities and limitations associated with the severely restricted reform of free choice, the statements concerning opportunities to make personal health decisions will lose their significance. The advocacy of discourses of freedom of choice seems therefore mostly like empty words, as they are producing weak patients instead of free and empowered people. As the reform was initiated in the beginning of 2000 it is rather fresh. The paper produces insights into the rhetoric of political promises and the limitations of the reform dealing with freedom of choice in health care.

  7. Piloting an online grocery store simulation to assess children's food choices.

    2016-01-01

    Public health interventions must address poor diet among U.S. children, but research is needed to better understand factors influencing children's food choices. Using an online grocery store simulation, this research piloted a novel method to assess children's snack selection in a controlled but naturalistic laboratory setting, evaluate predictors of choice, and experimentally test whether promotions on food packages altered choices. Children (7-12 years, N = 61) were randomly assigned to one of three conditions: promotions on healthy products; promotions on unhealthy products; and no promotions (control). They selected from a variety of healthy and unhealthy foods and beverages and rated all products on healthfulness and taste. Promotions on food packaging did not affect snack selection in this study, but findings supported our other hypothesis that perceived taste would be the strongest predictor of food choice. Children accurately rated product healthfulness, but these ratings did not predict healthy snack choices or taste ratings for healthy or unhealthy snacks. These results suggest that interventions to improve children's food choices should focus on increasing availability of healthy options and identifying opportunities to enhance children's liking of healthy options. However, nutrition education alone is unlikely to improve children's diets. Further testing is required, but the simulated online grocery store method shows potential for measuring children's food choices. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available This paper looks at two verbal descriptions of the Pear film and characterizes them according to the analysis proposed by Downing (1980 for factors influencing lexical choice. The two descriptions, one short and one long, were told by my Karo consultant, Mário Jorge Arara, after the exhibition of the film. Generally, the present article looks at Downing's assertion that "if the description is to be brief, words of broad referential scope are likely to be chosen (.... If the speaker opts for a more detailed description, more lexemes of narrower referential scope are likely to appear" (1980:90 and sees how this assertion applies to the two narratives. Specifically, it looks at each of the versions of the story and tries to explain the mentions of the referents by either basic or non-basic level categories in terms of cognitive, textual and contextual factors.

    Innumerable questions need to be answered and obstacles overcome before radioimmunotherapy can be generally successful in cancer patients. Major developments have greatly enhanced the likelihood of success. The important development of appropriate radionuclides and radiochemistry for this therapy must be intimately linked with the biological and biochemical realities. All aspects must be considered, such as the specific nature of the antigenic target, the pharmacokinetics of the antibody fragment carrier, the capability of in vivo quantitation of tumor uptake and turnover time, as well as total body kinetics. With this knowledge, then, practical radiochemistry methods can be integrated with the suitable radionuclide choices, and production methods can be developed which will deliver effective and dependable products for patient therapy

    2007-07-01

    Ten years after the first European Electricity Directive, the goal of creating a single European electricity market has not been reached, despite concerted efforts by the EU and certain member states to continue with the reforms. The policy of subsidiarity for many aspects of market design has as a consequence that member countries are implementing a variety of different market designs and are implementing the reforms at varying speeds. The Florence regulatory process, which was intended to provide a bottom-up approach for coordination and harmonization, has effectively stalled and been replaced by a series of 'mini fora' in which smaller groups of countries work on integrating their markets. At the same time, the European electricity supply industry is facing some significant challenges. This paper investigates the different choices that can be made in the design of electricity markets, how they relate to each other and how they relate to the policy goals. (auth)

  13. Estimating bacterial diversity for ecological studies: methods, metrics, and assumptions.

    Directory of Open Access Journals (Sweden)

    Julia Birtel

    Full Text Available Methods to estimate microbial diversity have developed rapidly in an effort to understand the distribution and diversity of microorganisms in natural environments. For bacterial communities, the 16S rRNA gene is the phylogenetic marker gene of choice, but most studies select only a specific region of the 16S rRNA to estimate bacterial diversity. Whereas biases derived from from DNA extraction, primer choice and PCR amplification are well documented, we here address how the choice of variable region can influence a wide range of standard ecological metrics, such as species richness, phylogenetic diversity, β-diversity and rank-abundance distributions. We have used Illumina paired-end sequencing to estimate the bacterial diversity of 20 natural lakes across Switzerland derived from three trimmed variable 16S rRNA regions (V3, V4, V5. Species richness, phylogenetic diversity, community composition, β-diversity, and rank-abundance distributions differed significantly between 16S rRNA regions. Overall, patterns of diversity quantified by the V3 and V5 regions were more similar to one another than those assessed by the V4 region. Similar results were obtained when analyzing the datasets with different sequence similarity thresholds used during sequences clustering and when the same analysis was used on a reference dataset of sequences from the Greengenes database. In addition we also measured species richness from the same lake samples using ARISA Fingerprinting, but did not find a strong relationship between species richness estimated by Illumina and ARISA. We conclude that the selection of 16S rRNA region significantly influences the estimation of bacterial diversity and species distributions and that caution is warranted when comparing data from different variable regions as well as when using different sequencing techniques.

    Lesakova Dagmar

    2014-01-01

    Full Text Available To attract and retain customers, an understanding of their motives and reasons for selecting particular food and grocery store is needed. This is of particular importance in the growing segment of seniors. The size of the senior's market demands a better understanding of the older consumer. The aim of our study is to identify psychographic characteristics of the elderly consumer, and to indicate the lifestyle groups and the relationship between these groups and retail store attributes. Differences in the motives for patronizing specific food stores are analyzed for lifestyle groups. We use the lifestyle as a segmentation variable in the diverse population of seniors for the reason, that the lifestyle of the elderly provides more valuable information than chronological age alone. This information can be used by retailers to improve marketing strategies in order to appeal to a target group of senior shoppers. Empirical research is based on a self-administrated questionnaire aimed on the identification of the lifestyle characteristics and retail store attributes of the consumers in 65+ age, used for the choice of food purchasing retail stores. Lifestyles characteristics were measured by the respondents activities, interests and opinions (AIO. The results of the research indicate that there are differences among the lifestyle groups with significant differences in attitudes towards quality of products or internal store environment. Our research demonstrates the value of psychographic information over age alone regarding the patronage factors in store selection. Our study is a part of the research project VEGA 1/0612/12 'Determinants of the size, structure and tendences in the individual consumption of seniors'.

We base our proposal on the observation that the literature on diversity management, both in the instrumental and critical traditions, is primarily concerned with fostering the diversity...... as the range of individual opinions and societal discourses that get expressed and can find resonance in organizational settings. We contribute to the literature on diversity management by moving away from a focus on individual-bound and inalterable criteria of diversity and toward a reconceptualization...... of diversity management as dynamic processes of voice articulation and mediation...

    Full Text Available Aim: To evaluate the diversity in techniques and approaches for anterior colporrhaphy among operators in Turkey. Methods: A survey evaluating the preoperative examination, technique of anterior colporrhaphy, operation choice and postoperative care was presented to surgeons. We contacted via directly, mail or telephone. We used 28 item questionnaire. Results: Majority (87.9% was composed of young gynecologists. Urologists composed of the 9.5% of the study population. The rate of paravaginal defect evaluation was 75.9% and mostly by inspection the presence of vaginal rugae. The use of transperineal 3D pelvic floor ultrasonography was low (5.7%. The evaluation of levator ani muscle defect was 46.6%. The usage of the transperineal 3D ultrasonography for levator ani muscle defect was 19 percent of operators. There were diversity in use of hydrodissection, fascial plication, excision of vaginal mucosa and suture choice. Usage of mesh for anterior colporrhaphy was limited (17.8% and mostly in recurrent cases (12.2%. Paravaginal defect repair rate was 31.9%. The urinary catheter was generally removed one or two day after operation. Vaginal pack usually removed 24 hours after. Conclusion: Several techniques and approaches for anterior vaginal wall repair among operators in Turkey. The variety of techniques suggested that there is no consensus on best surgical technique.

    Full Text Available Survey responses of producers and institutional buyers in northeastern Kansas (United States were analyzed to understand barriers and opportunities for sustainable food systems in the region where their emergence has been limited. Producers and buyers identified barriers previously noted regarding mismatches of available quantities and prices. Producers’ enthusiasm to supply locally exceeded buyers’ interest to source locally. Transportation was identified as one of the major concerns by producers, and their responses to choice tasks revealed producers’ preferences to sell locally while pricing their products to secure sales revenue and to cover their logistics expenses at least partially.

Objective: To determine the correlation between possibilities for making choices and expectations for the future with the quality of life in adults with intellectual disabilities according self-assessment and assessment by others. Methods: Descriptive, method of correlation and comparative analysis ware applied. From techniques, analysis of documents, surveys with the Quality of life questionnaire by Schalock and Keith and Questionnaire for expectations for the future by Speck, and scaling with the Scale for assessment of the opportunities for making choices by Kishi et al. Sample consisted of 130 intellectually disabled adults and 130 proxies. For establishing connection between the examined phenomena Pearson correlation coefficient (r was used, at p<0,01. Results: There is a strong correlation between the results obtained from the questionnaires about quality of life and opportunities for making choices, self-assessment r(130=0,497, p<0,01, assessment by others r(130=0,482, p<0,01. There is a correlation between the results obtained from the questionnaires about quality of life and expectations for the future, but not very strong, self-assessment r(130=0,233, p=0,008<0,01, assessment by others r(130=0,305, p<0,01. Conclusion: There is a correlation between opportunities for making choices and expectations for the future with the quality of life in adults with intellectual disabilities. To improve the quality of life in these individuals, it is necessary to design programs that will develop self-concept, abilities for self-determination and making personal choices.

    Transportation programming, a process of selecting projects for funding given budget and other constraints, is becoming more complex as a result of new federal laws, local planning regulations, and increased public involvement. This article describes the use of an integer programming tool, Multiple Choice Knapsack Problem (MCKP), to provide optimal solutions to transportation programming problems in cases where alternative versions of projects are under consideration. In this paper, optimization methods for use in the transportation programming process are compared and then the process of building and solving the optimization problems is discussed. The concepts about the use of MCKP are presented and a real-world transportation programming example at various budget levels is provided. This article illustrates how the use of MCKP addresses the modern complexities and provides timely solutions in transportation programming practice. While the article uses transportation programming as a case study, MCKP can be useful in other fields where a similar decision among a subset of the alternatives is required.

  3. Suboptimal Choice in Pigeons: Stimulus Value Predicts Choice over Frequencies.

    Directory of Open Access Journals (Sweden)

    Aaron P Smith

    Full Text Available Pigeons have shown suboptimal gambling-like behavior when preferring a stimulus that infrequently signals reliable reinforcement over alternatives that provide greater reinforcement overall. As a mechanism for this behavior, recent research proposed that the stimulus value of alternatives with more reliable signals for reinforcement will be preferred relatively independently of their frequencies. The present study tested this hypothesis using a simplified design of a Discriminative alternative that, 50% of the time, led to either a signal for 100% reinforcement or a blackout period indicative of 0% reinforcement against a Nondiscriminative alternative that always led to a signal that predicted 50% reinforcement. Pigeons showed a strong preference for the Discriminative alternative that remained despite reducing the frequency of the signal for reinforcement in subsequent phases to 25% and then 12.5%. In Experiment 2, using the original design of Experiment 1, the stimulus following choice of the Nondiscriminative alternative was increased to 75% and then to 100%. Results showed that preference for the Discriminative alternative decreased only when the signals for reinforcement for the two alternatives predicted the same probability of reinforcement. The ability of several models to predict this behavior are discussed, but the terminal link stimulus value offers the most parsimonious account of this suboptimal behavior.

  7. Challenges and opportunities await natural gas industry

    1998-01-01

    During the last two decades, the natural gas industry has gone through drastic changes. On one hand, deregulation and customer choice have been introduced to the industry. On the other hand, technological advances have resulted in substantial growth of available gas resources. In short, deregulation coupled with increased availability of supply has changed the way market participants interact with each other and which avenues they take to become leaders. Many new opportunities for entry into the market have also been created. As a result, the tide of competition has not only turned against the financially strong giants of the past, but it has also turned against new entrants who are fast, flexible and market driven. Natural gas utilities companies have responded by improving their operational efficiencies through process re-engineering, organizational re-alignment, restructuring and strategic alliances or mergers. Deregulation of the electricity industry is expected to increase competitive pressures on the natural gas industry, thus causing even more of a decrease in natural gas prices. In the future, natural gas utilities must be able to improve their effectiveness by accurately forecasting demand and optimizing their own supply and delivery systems in such a way that costs are minimized without compromising the reliability of supply. The new frontier of competitiveness will ensure that structural changes in the industry are characterized by an effective management of the supply-demand relationship and the optimization of risks inherently a part of gas delivery

    Newly available data on the spatial distribution of retail activities in cities makes it possible to build models formalized at the level of the single retailer. Current models tackle consumer location choices at an aggregate level and the opportunity new data offers for modeling at the retail unit level lacks an appropriate theoretical framework. The model we present here helps to address these issues. Based on random utility theory, we have built it around the idea of quantifying the role of floor-space and agglomeration in retail location choice. We test this model on the inner area of Greater London. The results are consistent with a super linear scaling of a retailer's attractiveness with its floorspace, and with an agglomeration effect approximated as the total retail floorspace within a 300 m radius from each shop. Our model illustrates many of the issues involved in testing and validating urban simulation models involving spatial data and its aggregation to different spatial scales.

    2012-04-01

    Full Text Available Diversity management is a process intended to create and maintain a positive work environment where the similarities and differences of individuals are valued. The literature on diversity management has mostly emphasized on organization culture; its impact on diversity openness; human resource management practices; institutional environments and organizational contexts to diversity-related pressures, expectations, requirements, and incentives; perceived practices and organizational outcomes related to managing employee diversity; and several other issues. The current study examines the potential barriers to workplace diversity and suggests strategies to enhance workplace diversity and inclusiveness. It is based on a survey of 300 IT employees. The study concludes that successfully managing diversity can lead to more committed, better satisfied, better performing employees and potentially better financial performance for an organization.

    Valuing and appreciating diversity are key requirements for health care organizations faced with increasingly diverse workforces and patient populations. Diversity issues are central to effectively functioning teams, patient outcomes, staff satisfaction, recruitment, and retention. Shands HealthCare, a health care system containing a large teaching medical center and several community hospitals and clinics centered around Gainesville, Florida, made a commitment to take the necessary steps to make diversity a priority and strategic initiative. A systemwide diversity initiative was launched in 1998. Diversity was defined, and organizational leaders were developed as "Ambassadors for Diversity." The Ambassadors developed an extensive training program that all staff and managers attend upon hiring. The primary goal of the program is to create a culture of respect and appreciation for diversity. Over 2,500 employees and managers have attended the training.

    Multiple attributes usually have to be assessed when choosing a mate. Efficient choice of the best mate is complicated if the available cues are not positively correlated, as is often the case during acoustic communication. Because of varying distances of signalers, a female may be confronted with signals of diverse quality at different intensities. Here, we examined how available cues are weighted for a decision by female crickets. Two songs with different temporal patterns and/or sound intensities were presented in a choice paradigm and compared with female responses from a no-choice test. When both patterns were presented at equal intensity, preference functions became wider in choice situations compared with a no-choice paradigm. When the stimuli in two-choice tests were presented at different intensities, this effect was counteracted as preference functions became narrower compared with choice tests using stimuli of equal intensity. The weighting of intensity differences depended on pattern quality and was therefore non-linear. A simple computational model based on pattern and intensity cues reliably predicted female decisions. A comparison of processing schemes suggested that the computations for pattern recognition and directionality are performed in a network with parallel topology. However, the computational flow of information corresponded to serial processing. © 2015. Published by The Company of Biologists Ltd.

    Norcen Energy Resources Limited's pursuit of international oil and gas opportunities since the late 1980s were outlined. By 1994 Norcen had exploration and production concessions in 12 countries stretching from Algeria, Russia, Argentina, Indonesia to offshore Australia. The company had seen its share of risks, opportunities and rewards. Since 1994 international efforts of the Company have been focused on lower risk opportunities with exploration upside in defined core areas of South America, particularly in Venezuela, a country with conventional, heavy and ultra-heavy oil resources exceeding that of Saudi Arabia. These, and other similar foreign investments in the formerly closed national oil industries of South America have been greatly facilitated by the political liberalization, economic reforms and stabilization that have taken place there over the past ten years. The story of Norcen's successful bidding on the Oritupano-Leona production block in 1993 and Delta Centro exploration block in 1996 was the subject of this presentation

    The varied career opportunities open to clinical engineers are described in this paper. Many of these opportunities are within the medical device industry in research, development, manufacturing design, regulatory activities, production, operations, sales, marketing, service, and management. Additional opportunities are available in hospitals, with the Veterans Administration, or working as an entrepreneur or a consultant. Each of these careers requires specific training and skills, and they all require a fundamental scientific knowledge of physical principles and mathematics. Research and management, however, require different educational preparation. The research emphasis should be on theoretical principles and creativity; the management emphasis should be on financial and labor problems. In all clinical engineering careers, the individual is a problem solver.

    The objective of this study is to test the extent to which, under different opportunities for market participation, the diversity of plant species rural households grow or collect (on-farm diversity), and the variety of foods mothers purchase (market diversity) are associated with their dietary diversity. Rural households from three districts in southern Benin were interviewed during dry (n = 472) and wet (n = 482) seasons between 2011 and 2012. Villages within districts and their households were selected randomly according to market accessibility, with a mother selected from each household. Information on on-farm diversity was collected using a semi-structured questionnaire. Market diversity was obtained through a 7-day food frequency questionnaire that elicited if foods were purchased. Dietary diversity was derived from a quantitative 24-hour food recall. A system of three simultaneous equations via a Generalized Methods of Moments was estimated to address potential endogeneity between dietary diversity and on-farm diversity and market diversity. Results show rich on-farm diversity with more than 65 different edible plant species grown or collected by households. More than 70% of foods consumed by mothers were purchased in 55 market places. More than 50% of mothers met minimum dietary diversity with at least 5 food groups consumed. Diagnostic tests indicated the existence of endogeneity. Econometric results showed that on-farm and market diversities were positively associated with mothers' dietary diversity (p market opportunities, seasonality and other socioeconomic factors were controlled for. Results provide evidence of a positive relationship between on-farm diversity and dietary diversity among participant mothers. They demonstrate the important contribution of market diversity to their dietary diversity.

    The decision by prosthodontic residency program directors to employ the Match process highlights the need to understand applicant priorities that influence their choice of which programs to rank highly. The purpose of this study is to determine the factors that were most important to residents when choosing from among nonmilitary based prosthodontics dental residency programs in the United States. Following completion of a pilot study, all currently enrolled prosthodontic residents at nonmilitary residency programs were invited to participate via the internet. The study consisted of a survey instrument asking residents to rank 26 possible factors that might impact an applicant's choice of residency program. In addition, the instrument collected other possible influencing variables including gender and debt load. Mean rank scores were compared to determine the most and least important factors. Kruskal-Wallis test was used to compare specific factors between the possible influencing variables. Two hundred and thirty residents completed the survey instrument, representing a 54.1% response rate of possible participants. With regard to factors influencing program choice, reputation of the residency program was the factor ranked the highest by participants, followed in descending order by the program director's personality, curriculum content, access to use of the latest digital technology, and opportunities for dental implant placement. Quality of schools for children, community outreach opportunities, and the ability to moonlight were ranked as the least important factors. Male and female residents ranked factors such as tuition/stipend, curriculum content, and community outreach opportunities significantly differently. Depending on debt load, residents ranked the factors tuition/stipend, ability to moonlight, curriculum content, and safety of the area where the program is differently. Current prosthodontic residents valued the reputation of the program as the most

    Directory of Open Access Journals (Sweden)

    Neil Martin

    2016-05-01

    Full Text Available Thomas Schelling’s The Strategy of Conflict carries significant behavioral implications which have been overlooked by economic readers. I argue that these implications are central to Schelling’s vision of game theory, that they fit well with recent advances in experimental psychology and behavioral economics, and provide a comprehensive framework that can inform research on strategy. In my view, Schelling develops a non-mathematical approach to strategy which anticipates on Gigerenzer and Selten’s “ecological rationality” program. This approach maps the processes involved in strategic reasoning and highlights their reliance on the particular information structure of interactive social environments. Building on this approach, I model strategy as a heuristic form of reasoning that governs the way in which individuals search for and provide cues in situations of mutually contingent choice. I conclude by examining how the reference to ecological rationality can help clarify Schelling’s contribution to game theory and outline potential avenues of research into strategic reasoning and interaction.

    2017-04-01

    This study sought to determine whether and to what extent medical students with an undergraduate college major in neuroscience, relative to other college majors, pursue psychiatry relative to other brain-based specialties (neurology and neurosurgery) and internal medicine. The authors analyzed data from AAMC matriculation and graduation surveys for all students who graduated from US medical schools in 2013 and 2014 (n = 29,714). Students who majored in neuroscience, psychology, and biology were compared to all other students in terms of their specialty choice at both time points. For each major, the authors determined rates of specialty choice of psychiatry, neurology, neurosurgery, and, for comparison, internal medicine. This study employed Chi-square statistic to compare odds of various specialty choices among different majors. Among medical students with an undergraduate neuroscience major (3.5% of all medical students), only 2.3% preferred psychiatry at matriculation, compared to 21.5% who chose neurology, 13.1% neurosurgery, and 11% internal medicine. By graduation, psychiatry specialty choice increased to 5.1% among neuroscience majors while choice of neurology and neurosurgery declined. Psychology majors (OR = 3.16, 95% CI 2.60-4.47) but not neuroscience majors (OR 1.28, 0.92-1.77) were more likely than their peers to choose psychiatry. Psychiatry struggles to attract neuroscience majors to the specialty. This missed opportunity is an obstacle to developing the neuroscience literacy of the workforce and jeopardizes the neuroscientific future of our field. Several potential strategies to address the recruitment challenges exist.

  9. Dynamic cognitive models of intertemporal choice.

    Dai, Junyi; Pleskac, Timothy J; Pachur, Thorsten

    2018-03-24

    Traditionally, descriptive accounts of intertemporal choice have relied on static and deterministic models that assume alternative-wise processing of the options. Recent research, by contrast, has highlighted the dynamic and probabilistic nature of intertemporal choice and provided support for attribute-wise processing. Currently, dynamic models of intertemporal choice-which account for both the resulting choice and the time course over which the construction of a choice develops-rely exclusively on the framework of evidence accumulation. In this article, we develop and rigorously compare several candidate schemes for dynamic models of intertemporal choice. Specifically, we consider an existing dynamic modeling scheme based on decision field theory and develop two novel modeling schemes-one assuming lexicographic, noncompensatory processing, and the other built on the classical concepts of random utility in economics and discrimination thresholds in psychophysics. We show that all three modeling schemes can accommodate key behavioral regularities in intertemporal choice. When empirical choice and response time data were fit simultaneously, the models built on random utility and discrimination thresholds performed best. The results also indicated substantial individual differences in the dynamics underlying intertemporal choice. Finally, model recovery analyses demonstrated the benefits of including both choice and response time data for more accurate model selection on the individual level. The present work shows how the classical concept of random utility can be extended to incorporate response dynamics in intertemporal choice. Moreover, the results suggest that this approach offers a successful alternative to the dominating evidence accumulation approach when modeling the dynamics of decision making.

    The gap in educational attainment separating underrepresented minorities from Whites and Asians remains wide. Such a gap has significant impact on workforce diversity and inclusion among cross-cutting Biomedical Data Science (BDS) research, which presents great opportunities as well as major challenges for addressing health disparities. This article provides a brief description of the newly established National Institutes of Health Big Data to Knowledge (BD2K) diversity initiatives at four universities: California State University, Monterey Bay; Fisk University; University of Puerto Rico, Río Piedras Campus; and California State University, Fullerton. We emphasize three main barriers to BDS careers (ie, preparation, exposure, and access to resources) experienced among those pioneer programs and recommendations for possible solutions (ie, early and proactive mentoring, enriched research experience, and data science curriculum development). The diversity disparities in BDS demonstrate the need for educators, researchers, and funding agencies to support evidence-based practices that will lead to the diversification of the BDS workforce.

    The range of business opportunities currently available for the midstream oil and gas business were discussed with particular focus on storage opportunities. Alberta Energy Co. (AEC) Ltd.'s two midstream business units include AEC Pipelines and Gas Processing, and AEC Storage and Hub Services. These two businesses provide the company with good investment returns, stable cash flow, and some significant strategic synergies with their exploration and production businesses. In 1988, the AECO C Hub in southeastern Alberta was created as an outgrowth of AEC's gas production operations on the Suffield block, where they had depleted gas reservoirs with high rock quality suitable for high deliverability storage. With the AECO C Hub, AEC was able to offer firm storage contracts of from 1 to 20 years, and to introduce short term interruptible parking and lending services, title exchange, a spot price index for greater price discovery, and an electronic nomination system. AEC is currently completing construction of their second commercial storage facility, the Wild Goose project, in northern California. D ebottlenecking' the Western Canada supply basin should provide additional opportunities for further expansion not only for AEC but also for other midstream service providers. Opportunities are especially available in the areas of new storage facilities to serve location-specific needs, replacement of declining storage capacity, replacement of retiring facilities, technological optimization of existing facilities, more flexible, higher deliverability facilities and commercial optimization of existing facilities. A map of the hubs and market centres of North America are included. 5 figs

    A growing literature demonstrates that using a foreign language affects choice. This is surprising because if people understand their options, choice should be language independent. Here, we review the impact of using a foreign language on risk, inference, and morality, and discuss potential explanations, including reduced emotion, psychological distance, and increased deliberation.

  11. Interprofessional Education: Opportunities and Challenges for Psychology.

    Science.gov (United States)

    Ward, Wendy; Zagoloff, Alexandra; Rieck, Cortney; Robiner, William

    2018-02-16

    This manuscript is an outgrowth of an invited panel presentation at the national Association for Psychologists in Academic Health Centers Conference in 2017 on Interprofessional Education (IPE). IPE is a structured and transformative educational strategy designed to provide active learning experiences where trainees from diverse healthcare professions gain shared content knowledge plus collaboration skills as they learn about, from, and with each other. Collaboration skills include understanding professional role distinctions and overlap, effective team-based communication, shared values/ethics and respect for each other's expertise, and teamwork dynamics. It is increasingly important to expand training beyond the intraprofessional activities in which psychology trainees engage to prepare them to participate in interprofessional collaborative care. As healthcare systems move to team-based collaborative practice and value-based reimbursement models, the profession of psychology needs leaders at every academic health center to facilitate the design and/or implementation of IPE activities. The panel of psychologists presented roles that psychologists play in IPE institutional program design and implementation, graduate training programs, and the perspectives of an early career psychologist and psychology trainee. Opportunities and challenges are highlighted, culminating in a call to action. Psychologists must embrace their identity as health professionals and engage their learners in IPE so that the emerging cognitive schemata of healthcare that is developed includes the profession of psychology. Otherwise, healthcare teams and health professionals will not understand the value, roles, or potential contributions of psychologists in enhancing patient care outcomes, ultimately jeopardizing psychologists' referrals, involvement in healthcare delivery, and career opportunities.

  12. Rational choice in field archaelology

    Directory of Open Access Journals (Sweden)

    Cătălin Pavel

    2011-11-01

    Full Text Available In the present article I attempt to apply advances in the study of instrumental and epistemic rationality to field archaeology in order to gain insights into the ways archaeologists reason. The cognitive processes, particularly processes of decision making, that enable archaeologists to conduct the excavation in the trench have not been adequately studied so far. I take my cues from two different bodies of theory. I first inquire into the potential that rational choice theory (RCT may have in modeling archaeological behaviour, and I define subjective expected utility, which archaeologists attempt to maximize, in terms of knowledge acquisition and social gain. Following Elster’s criticism of RCT, I conclude that RCT’s standards for rational action do not correspond with those ostensibly used in field archaeology, but that instrumental rationality has a prominent role in the “archaeological experiment”. I further explore if models proposed as reaction to RCT may account for archaeological decision making. I focus on fast and frugal heuristics, and search for archaeological illustrations for some of the cognitive biases that are better documented in psychological literature. I document confirmation and congruence biases, the endowment effect, observer-expectancy bias, illusory correlation, clustering illusion, sunk cost bias, and anchoring, among others and I propose that some of these biases are used as cognitive tools by archaeologists at work and retain epistemic value. However, I find formal logic to be secondary in the development of archaeological reasoning, with default logic and defeasible logic being used instead. I emphasize scientific knowledge as an actively negotiated social product of human inquiry, and conclude that to describe rationality in field archaeology a bounded rationality model is the most promising avenue of investigation.

  15. Linking Diversity and Differentiation

    Directory of Open Access Journals (Sweden)

    Hans-Rolf Gregorius

    2010-03-01

    Full Text Available Generally speaking, the term differentiation refers to differences between collections for the distribution of specified traits of their members, while diversity deals with (effective numbers of trait states (types. Counting numbers of types implies discrete traits such as alleles and genotypes in population genetics or species and taxa in ecology. Comparisons between the concepts of differentiation and diversity therefore primarily refer to discrete traits. Diversity is related to differentiation through the idea that the total diversity of a subdivided collection should be composed of the diversity within the subcollections and a complement called “diversity between subcollections”. The idea goes back to the perception that the mixing of differentiated collections increases diversity. Several existing concepts of “diversity between subcollections” are based on this idea. Among them, β-diversity and fixation (inadvertently called differentiation are the most prominent in ecology and in population genetics, respectively. The pertaining measures are shown to quantify the effect of differentiation in terms of diversity components, though from a dual perspective: the classical perspective of differentiation between collections for their type compositions, and the reverse perspective of differentiation between types for their collection affiliations. A series of measures of diversity-oriented differentiation is presented that consider this dual perspective at two levels of diversity partitioning: the overall type or subcollection diversity and the joint type-subcollection diversity. It turns out that, in contrast with common notions, the measures of fixation (such as FST or GST refer to the perspective of type rather than subcollection differentiation. This unexpected observation strongly suggests that the popular interpretations of fixation measures must be reconsidered.

  16. Motives for food choice among Serbian consumers

    Directory of Open Access Journals (Sweden)

    Gagić Snježana

    2014-01-01

    Full Text Available People's motives for food choice depend on a number of very complex economic, social and individual factors. A Food Choice Questionnaire (FCQ, an instrument that measures the importance of factors underlying food choice, was used to reveal the Serbian consumers' food choice motives by survey of 450 respondents of different age groups. A confirmatory factor analysis was conducted on the motive items, using 11 factors. Previous research shows that the nutrition in Serbia is not balanced enough, and therefore the analysis of motives for food choice is considered a useful tool for the planning of more efficient public policies and interventions aimed at influencing healthier eating habits. Hence the results can be useful for researchers as well as for public institutions which deal with creating the strategy of public health or businessmen who produce and sell food products, because knowing consumer behaviour is necessary for product success on the market.
