The Effect of Social Desirability Bias on Willingness-To-Pay for Organic Beef.

Researchers regularly conduct willingness-to-pay or valuation studies for product marketing or public policy purposes. However, a large volume of research suggests valuation tools such as conjoint analysis may be subject to social desirability bias, where subjects misrepresent their true preferences to create a favorable impression. The objective of this study is to measure the effects of social desirability bias on conjoint survey responses. Consumers were asked to rank organic ground beef relative to other ground beef products at various prices. A popular scale measuring individuals’ tendency to exhibit social desirability bias was also administered. Regression analysis found no correlation between individuals’ social desirability scale scores and their preferences for organic beef. Thus, in this study, social desirability bias does not appear to be a problem for valuation researchers.Consumer/Household Economics, Livestock Production/Industries,

The Cycle of Judicial Elections: Texas as a Case Study

This Article addresses the concerns about the implications of an elected judiciary. Advocating for overall reform, the Article presents Texas as a case study. It tracks the cycle of change in Texas, from party appointments to the bench to two-party competition and back towards one-party dominance. The Article discusses the problems these changes caused and addresses the attempted reform efforts

Genetic composition of an exponentially growing cell population

We study a simple model of DNA evolution in a growing population of cells. Each cell contains a nucleotide sequence which randomly mutates at cell division. Cells divide according to a branching process. Following typical parameter values in bacteria and cancer cell populations, we take the mutation rate to zero and the final number of cells to infinity. We prove that almost every site (entry of the nucleotide sequence) is mutated in only a finite number of cells, and these numbers are independent across sites. However independence breaks down for the rare sites which are mutated in a positive fraction of the population. The model is free from the popular but disputed infinite sites assumption. Violations of the infinite sites assumption are widespread while their impact on mutation frequencies is negligible at the scale of population fractions. Some results are generalised to allow for cell death, selection, and site-specific mutation rates. For illustration we estimate mutation rates in a lung adenocarcinoma

Recircumscription of the Nepenthes alata group (Caryophyllales: Nepenthaceae) in the Philippines : with four new species

An overview of Nepenthes in the Philippines is presented. Four new species, Nepenthes extincta sp. nov., N. kitanglad sp. nov., N. kurata sp. nov. and N. leyte sp. nov. are described and illustrated from the Philippines and placed in the Nepenthes alata group. An updated circumscription and key to the species of the group is provided. Delimitation and comparison with the Regiae group is given. All four of the newly described species are assessed as threatened using the International Union for the Conservation of Nature 2012 standard, and one, N. extincta sp. nov. is considered likely to be already extinct due to open-cast mining. Logging and conversion of forest habitat are thought to be the main threats to the other three species

Sustainability Children\u27s Book

As human driven climate change continues to alter our planet, persuading the general public to adopt sustainable living practices has become increasingly important. Storytelling has long been a part of human culture, and recent studies have emphasized the power of storytelling to influence the audience as a means of changing behavior. This project attempted to teach sustainable principles to primary school children through the creation of a scientific children’s book. The book communicated the maxim of “reduce, reuse, recycle” by tracing a fictitious story of a town where children frequently buy new toys and throw the old toys away. The book explores the supply chain of toys and the market forces of supply and demand, focusing on the consumer’s responsibility to not over-consume, i.e “reduce”. It also presents the concept of “reusing” and “recycling” as alternatives to disposal of old toys. The book was evaluated for age appropriate language and concepts for K-5 students and adjusted to meet educational standards. It was then tested by reading it to a classroom of 2nd grade students. A discussion with the students following the reading showed that they understood the theme of the book and how they could apply it to their own lives. The project also included a life cycle analysis (LCA) of a stuffed animal, a representative toy from the story. The LCA showed that the largest contributors to the stuffed animal’s impacts were the production of cotton used for its outer layer and the electricity used in its assembly. It also showed the impacts most damaging to human health were chiefly a result of the fossil fuels used to provide process energy

Analysis of photopole data reduction models

An analysis of the total impulse obtained from a buried explosive charge can be calculated from displacement versus time points taken from successive film frames of high speed motion pictures of the explosive event. The indicator of that motion is a pole and baseplate (photopole), which is placed on or within the soil overburden. Here, researchers are concerned with the precision of the impulse calculation and ways to improve that precision. Also examined here is the effect of each initial condition on the curve fitting process. It is shown that the zero initial velocity criteria should not be applied due to the linear acceleration versus time character of the cubic power series. The applicability of the new method to photopole data records whose early time motions are obscured is illustrated

Research knowledge and skills in primary medical training: A crosssectional audit

This article was migrated. The article was marked as recommended. Background: Internationally, medical education has either adopted, or is moving toward, a Masters level qualification at completion. This reflects the higher-level learning outcomes and potentially facilitation of thinking and decision-making required of medical graduates. In Australia, the main difference between bachelor and masters programs appears to be the level of research skills training. This study explores the characteristics of research training in medical schools and alignment with higher education qualification frameworks. Methods: A cross-sectional audit was conducted of 22 medical schools in Australia and New Zealand, seeking information on: degree type, entry requirement, research knowledge and skills taught, teaching format, and barriers to offering students research experiences. Results: Information about 15 medical programs was obtained, with Australian Qualifications Framework or New Zealand Qualifications Framework Level 7, 8 or 9E outcomes. All included a variety of teaching methods on biomedical ethics, principles of evidence-based practice, and search strategies for medical evidence, critical appraisal of the literature and disease surveillance/epidemiology. Small projects were available in all programs, although voluntary in Level 7/8 programs and mandatory in Level 9E programs. Conclusions: There appear to be few differences in research training and learning outcomes from Level 7 and Level 9E programs, although Level 9E programs have a more systematic approach and assurance that all graduates can achieve the higher outcomes. Barriers to successful implementation relate to finding curriculum space and sufficient research training capacity for all medical students.</ns4:p

What is Ailing the German Economy? A Critical Analysis of German Social Market Economics

This paper offers a narrative historical description of the German Social Market Economy, from its inception following World War II, up to the recent Agenda 2010 reforms enacted under the administration of Chancellor Gerhard Schroder. It is the purpose of this work to explore why the German Social Market System enjoyed such a high degree of success in its early years, and which flaws might be causing the chronic problems of low growth and high unemployment that have plagued Germany more recently. In particular, the paper argues that a high-cost and highly inflexible labor market resulting from Germany\u27s system of autonomous collective wage bargaining may be stymieing business growth and scaring away foreign investment

Physiotherapy and the shadow of prostitution: the Society of Trained Masseuses and the massage scandals of 1894

In 1894 the Society of Trained Masseuses (STM) formed in response to massage scandals published by the British Medical Journal (BMJ). The Society's founders acted to legitimise massage, which had become sullied by its association with prostitution. This study analyses the discourses that influenced the founders of the Society and reflects upon the social and political conditions that enabled the STM to emerge and prosper. The founders established a clear practice model for massage which effectively regulated the sensual elements of contact between therapist and patient. Massage practices were regulated through clearly defined curricula, examinations and the surveillance of the Society's members. A biomechanical model of physical rehabilitation was adopted to enable masseuses to view the body as a machine rather than as a sensual being. Medical patronage of the Society was courted enabling the Society to prosper amongst competing organisations. Using Foucault's work on power we explore the contingent nature of these events, seeing the massage scandals in context with broader questions of sexual morality, professionalisation and expertise in the late nineteenth century society. We argue that many of the technologies developed by the founders resonate with physiotherapy practice today and enable us to critically analyse the continued relevance of the profession to contemporary healthcare
