Understanding factors that influence food choice may help improve diet quality. Factors that commonly affect adults' food choices have been described, but measures that identify and assess food choice factors specific to college students are lacking. This study developed and tested the Food Choice Priorities Survey (FCPS) among college students. Thirty-seven undergraduates participated in two focus groups ( n = 19; 11 in the male-only group, 8 in the female-only group) and interviews ( n = 18) regarding typical influences on food choice. Qualitative data informed the development of survey items with a 5-point Likert-type scale (1 = not important, 5 = extremely important). An expert panel rated FCPS items for clarity, relevance, representativeness, and coverage using a content validity form. To establish test-retest reliability, 109 first-year college students completed the 14-item FCPS at two time points, 0-48 days apart ( M = 13.99, SD = 7.44). Using Cohen's weighted κ for responses within 20 days, 11 items demonstrated moderate agreement and 3 items had substantial agreement. Factor analysis revealed a three-factor structure (9 items). The FCPS is designed for college students and provides a way to determine the factors of greatest importance regarding food choices among this population. From a public health perspective, practical applications include using the FCPS to tailor health communications and behavior change interventions to factors most salient for food choices of college students.

Factors Influencing Food Choice for Independently Living Older People-A Systematic Literature Review.

Unyielding, disproportionate growth in the 65 years and older age group has precipitated serious concern about the propensity of health and aged-care services to cope in the very near future. Preservation of health and independence for as long as possible into later life will be necessary to attenuate demand for such services. Maintenance of nutritional status is acknowledged as fundamental for achievement of this aim. Determinants of food choice within this age group need to be identified and better understood to facilitate the development of pertinent strategies for encouraging nutritional intakes supportive of optimal health. A systematic review of the literature consistent with PRISMA guidelines was performed to identify articles investigating influences on food choice among older people. Articles were limited to those published between 1996 and 2014 and to studies conducted within countries where the dominant cultural, political and economic situations were comparable to those in Australia. Twenty-four articles were identified and subjected to qualitative analysis. Several themes were revealed and grouped into three broad domains: (i) changes associated with ageing; (ii) psychosocial aspects; and (iii) personal resources. Food choice among older people is determined by a complex interaction between multiple factors. Findings suggest the need for further investigations involving larger, more demographically diverse samples of participants, with the inclusion of a direct observational component in the study design.

To identify the relative importance of extrinsic determinants of doctors' choice of specialty. A self-administered postal questionnaire. Australian vocational training programs. 4259 Australian medical graduates registered in September 2002 with one of 16 Australian clinical colleges providing vocational training programs. Choice of specialist vocational training program; extrinsic factors influencing choice of program, and variation by sex, age, marital status and country of birth. In total, 79% of respondents rated "appraisal of own skills and aptitudes" as influential in their choice of specialty followed by "intellectual content of the specialty" (75%). Extrinsic factors rated as most influential were "work culture" (72%), "flexibility of working arrangements" (56%) and "hours of work" (54%). We observed variation across training programs in the importance ascribed to factors influencing choice of specialty, and by sex, age and marital status. Factors of particular importance to women, compared with men, were "appraisal of domestic circumstances" (odds ratio [OR], 1.9), "hours of work" (OR, 1.8) and "opportunity to work flexible hours" (OR, 2.6). Partnered doctors, compared with single doctors, rated "hours of work" and "opportunity to work flexible hours" as more important (OR, 1.3), while "domestic circumstances" was more important to doctors with children than those without children (OR, 1.7). In total, 80% of doctors had chosen their specialty by the end of the third year after graduation. Experience with discipline-based work cultures and working conditions occurs throughout medical school and the early postgraduate years, and most doctors choose their specialty during these years. It follows that interventions to influence doctors' choice of specialty need to target these critical years.

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

Targeted efforts are needed to increase the number of medical students choosing psychiatry, but little is known about when students decide on their specialty or what factors influence their choice. The authors examined the timing and stability of student career choice of psychiatry compared with other specialties and determined what pre- and intra-medical school factors were associated with choosing a career in psychiatry. Using survey data from students who graduated from U.S. allopathic medical schools in 2013 and 2014 (N=29,713), the authors computed rates of psychiatry specialty choice at the beginning and end of medical school and assessed the stability of that choice. A multivariate-adjusted logistic regression and recursive partitioning were used to determine the association of 29 factors with psychiatry specialty choice. Choice of psychiatry increased from 1.6% at the start of medical school to 4.1% at graduation. The stability of psychiatry specialty choice from matriculation to graduation, at just over 50%, was greater than for any other specialty. However, almost 80% of future psychiatrists did not indicate an inclination toward the specialty at matriculation. A rating of "excellent" for the psychiatry clerkship (odds ratio=2.66), a major in psychology in college (odds ratio=2.58), and valuing work-life balance (odds ratio=2.25) were the factors most strongly associated with psychiatry career choice. Students who enter medical school planning to become psychiatrists are likely to do so, but the vast majority of students who choose psychiatry do so during medical school. Increasing the percentage of medical students with undergraduate psychology majors and providing an exemplary psychiatry clerkship are modifiable factors that may increase the rate of psychiatry specialty choice.

College administrative and management leaders, foodservice personnel, and student residents value social, nutritional, financial, and environmental sustainability in their dining expectations. Menu choice reduction looks promising as a strategy to achieve these goals. However, foodservice research about dominant attitudes across these stakeholders is limited. To identify qualitative views from all stakeholders about choice reduction to ensure that any changes to the meal service are not to the detriment of consumer satisfaction. A comprehensive list of 74 statements representing the spectrum of attitudes surrounding choice was generated by searching a variety of resources, including academic literature and Internet sites, and by conducting semistructured interviews with stakeholders. A final set of 42 statements resulted from researcher scrutiny for optimum balance, clarity, appropriateness, simplicity, and applicability. A new sample of participants was then asked to sort these 42 statements into a normal distribution grid from "strongly disagree" to "strongly agree." A purposive convenience sample of stakeholders (staff n=5 and residents n=4) was used to identify statements about choice reduction. A second sample of stakeholders (staff n=6 and residents n=29) were recruited to sort the final 42 statements. Q methodology analysis techniques were used. This involved conducting a by-person factor analysis, using the centroid factor extraction method because of the permissiveness it allows for data exploration. A varimax factor rotation to enhance interpretability of the results identified shared viewpoints. Three dominant viewpoints toward the possibility of choice reduction in the meal service were identified. Factor 1 was "health driven" (in which healthiness was paramount). Factor 2 was "variety seekers" (in which choice had instrumental value). Factor 3 was "choice lovers" (in which choice had intrinsic value). Although participants could see a number of

To assess the extent to which some factors influenced the choice of toothpastes and toothbrushes among dental patients in a Nigerian teaching hospital. Two-hundred and two patients were interviewed on factors that influenced their choice of toothbrush and toothpaste. Some of the factors considered include the cost, packaging, brand, media advertisement and their previous experience. Factors that affected choice of toothbrush by respondents included texture (89.6%), brand (62.9%), previous experience (64.4%) and for toothpaste, fluoride content (62.4%), previous experience (69.3%), and advice by a dentist (55.0%). Media advertisement was the least influential in their choice of toothpaste (29.2%) and toothbrush (24.3%). Consideration for fluoride was a stronger factor than herbal contents in the choice of toothpaste (P<0.001). Previous experience seems to be a very strong factor in the choice of both the toothbrush and toothpaste in this study, which suggest that for as long as the respondents are satisfied with a particular product, they will stick to it.

Little is known about consumers' behavior especially their choice behavior toward purchasing and consuming dairy products in developing countries. Hence, the aim of the present work is understanding the factors that affect on consumers' choice behavior toward dairy products in Iran. The study applies the theory of consumption values, which includes the functional values (taste, price, health, and body weight), social value, emotional value, conditional value and epistemic value. The sample were 1420 people (men and women). The data was collected using face to face survey in summer and fall 2015. Chi-square, confirmatory factor analysis, and structural equation modelling is used to assess data collected. The results indicate that functional values, social value, emotional value and epistemic value have a positive impact on choosing dairy products and conditional value didn't have a positive impact. It was concluded that the main influential factors for consumers' choice behavior toward dairy products included consumers experience positive emotion (e.g. enjoyment, pleasure, comfort and feeling relaxed) and functional value-health. This study emphasized the proper pricing of dairy products by producers and sellers. Copyright © 2016 Elsevier Ltd. All rights reserved.

Companion of choice at birth: factors affecting implementation.

Kabakian-Khasholian, Tamar; Portela, Anayda

2017-08-31

Two recent recommendations made by the World Health Organization confirm the benefits of companion of choice at birth on labour outcomes; however institutional practices and policies do not always support its implementation in different settings around the world. We conducted a review to determine factors that affect implementation of this intervention considering the perspectives and experiences of different stakeholders and other institutional, systemic barriers and facilitators. Forty one published studies were included in this review. Thirty one publications were identified from a 2013 Cochrane review on the effectiveness of companion of choice at birth. We also reviewed 10 qualitative studies conducted alongside the trials or other interventions on labour and birth companionship identified through electronic searches. The SURE (Supporting the Use of Research Evidence) framework was used to guide the thematic analysis of implementation factors. Women and their families expressed appreciation for the continuous presence of a person to provide support during childbirth. Health care providers were concerned about the role of the companion and possible interference with activities in the labour ward. Allocation of resources, organization of care, facility-related constraints and cultural inclinations were identified as implementation barriers. Prior to introducing companion of choice at birth, understanding providers' attitudes and sensitizing them to the evidence is necessary. The commitment of the management of health care facilities is also required to change policies, including allocation of appropriate physical space that respects women's privacy. Implementation research to develop models for different contexts which could be scaled up would be useful, including documentation of factors that affected implementation and how they were addressed. Future research should also focus on documenting the costs related to implementation, and on measuring the impact of

A review of factors affecting the food choices of disadvantaged women.

Lawrence, W; Barker, M

2009-05-01

The diets of young women are important not just for their own health but also for the long-term health of their offspring. Unbalanced unvaried diets are more common amongst poor and disadvantaged women. If the diets of these women are to be improved, it is first necessary to understand why they make the food choices they do. Influences on women's food choices range from the global to the individual: environmental factors, such as difficulty in acquiring and affording good-quality healthy foods; social support and social relationships, such as those with parents, spouses and children; life transitions, such as leaving home, living with a partner or having children; individual factors, such as having low perceived control or self-efficacy in making food choices and placing a low value on health in general and on their own health in particular. These interrelated factors all influence food choice, suggesting that if the diets of disadvantaged women are to be improved, it will be necessary to do more than simply educate about the link between diet and health.

To know the factors listed by puerperal woman that influenced the choice in type of delivery. Qualitative research, developed with 25 puerperal women in a University Hospital of Mato Grosso do Sul, between September and November 2014. A semi-structured interview was used for data collection and the Collective Subject Discourse was used to organize and tabulate the data collected. The Collective Subject Discourses resulted in the following categories: Desire for the type of delivery; Respect for the chosen type of delivery and Factors that influenced the choice. Most of the women interviewed (76%) expressed a preference for normal birth due to rapid recovery, less pain and suffering. The influence of family members, previous experience with childbirth, professional-customer interaction and internet information influenced the type of delivery chosen, which reinforces the importance of health education since the pre-natal stage, highlighting the need to equip women to perform a conscious choice.

Corrigan, Mark A; Shields, Conor J; Redmond, Henry P

2007-10-01

The aim of this study was to analyze the factors that influence the advancement and the career choices of doctors and medical students. Using the combined databases of the iformix and surgent websites, 450 doctors and medical students were invited to complete an internet-based survey. Surgent (http://www.surgent.ie) and iformix (http://www.iformix.com) are two free internet services administered by the authors. Surgent is a medical educational website, while iformix facilitates the online submission of abstracts to surgical and medical conferences across Britain and Ireland. The combined database of these two websites is approximately 4500 entries. Four hundred and fifty users represented a 10% sample based on an expected 40%-45% response rate. This was anticipated to yield between 180 and 202 respondents, statistically sufficient to analyze the data. A detailed Likert scale assessed the importance of "academic," "clinical," and "lifestyle" factors in determining career choice and progression. Analysis included descriptive statistics and inferential testing. Fifty percent (N = 222) of surveys were returned; 142 men and 78 women. Thirty-seven percent of respondents were Irish, 28% British, and 35% non-European. Fifteen percent were undergraduates, 4% interns, 12% had 2-4 years of clinical experience, while 69% had completed more than 4 years. Fifty-six percent had decided upon a career in general surgery. Overall, the most important factors for career choice were intellectual challenge (95%), academic opportunities (61%), and research opportunities(54%). Doctors with more than 4 years of experience deemed duration of training (p = 0.002), lifestyle during training (p = 0.02), and stress (0.005) as less important factors when considering career choice. Correlation analyses demonstrated that prestige (p = 0.002), patient relationships (p = 0.006), and advice from friends or family (p = 0.01) were more important influencing factors for interns.

Bold, Krysten W.; Yoon, Haewon; Chapman, Gretchen B.; McCarthy, Danielle E.

2013-01-01

This study aimed to expand the current understanding of smoking maintenance mechanisms by examining how putative relapse risk factors relate to a single behavioral smoking choice using a novel laboratory smoking-choice task. After 12 hours of nicotine deprivation, participants were exposed to smoking cues and given the choice between smoking up to two cigarettes in a 15-minute window or waiting and receiving four cigarettes after a delay of 45 minutes. Greater nicotine dependence, higher impulsivity, and lower distress tolerance were hypothesized to predict earlier and more intensive smoking. Out of 35 participants (n=9 female), 26 chose to smoke with a median time to a first puff of 1.22 minutes (standard deviation=2.62 min, range=0.03–10.62 min). Survival analyses examined latency to first puff, and results indicated that greater pre-task craving and smoking more cigarettes per day were significantly related to smoking sooner in the task. Greater behavioral disinhibition predicted shorter smoking latency in the first two minutes of the task, but not at a delay of more than two minutes. Lower distress tolerance (reporting greater regulation efforts to alleviate distress) was related to more puffs smoked and greater nicotine dependence was related to more time spent smoking in the task. This novel laboratory smoking-choice paradigm may be a useful laboratory analog for the choices smokers make during cessation attempts and may help identify factors that influence smoking lapses.

The goal of the current study was to examine the critical factors indicative of an individual's choice to access low vision rehabilitation services. Seven hundred and forty-nine visually impaired individuals, from the Montreal Barriers Study, completed a structured interview and questionnaires (on visual function, coping, depression, satisfaction with life). Seventy-five factors from the interview and questionnaires were entered into a data-driven Classification and Regression Tree Analysis in order to determine the best predictors of awareness group: positive personal choice (I knew and I went), negative personal choice (I knew and did not go), and lack of information (Nobody told me, and I did not know). Having a response of moderate to no difficulty on item 6 (reading signs) of the Visual Function Index 14 (VF-14) indicated that the person had made a positive personal choice to seek rehabilitation, whereas reporting a great deal of difficulty on this item was associated with a lack of information on low vision rehabilitation. In addition to this factor, symptom duration of under nine years, moderate difficulty or less on item 5 (seeing steps or curbs) of the VF-14, and an indication of little difficulty or less on item 3 (reading large print) of the VF-14 further identified those who were more likely to have made a positive personal choice. Individuals in the lack of information group also reported greater difficulty on items 3 and 5 of the VF-14 and were more likely to be male. The duration-of-symptoms factor suggests that, even in the positive choice group, it may be best to offer rehabilitation services early. Being male and responding moderate difficulty or greater to the VF-14 questions about far, medium-distance and near situations involving vision was associated with individuals that lack information. Consequently, these individuals may need additional education about the benefits of low vision services in order to make a positive personal choice. © 2014

The purpose of this study was to determine the relationship between personality traits, using the Five-Factor Model, and characteristics and motivational factors affecting specialty choice in Korean medical students. A questionnaire survey of Year 4 medical students (n=110) in July 2015 was administered. We evaluated the personality traits of Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness by using the Korean version of Big Five Inventory. Questions about general characteristics, medical specialties most preferred as a career, motivational factors in determining specialty choice were included. Data between five personality traits and general characteristics and motivational factors affecting specialty choice were analyzed using Student t-test, Mann-Whitney test and analysis of variance. Of the 110 eligible medical students, 105 (95.4% response rate) completed the questionnaire. More Agreeableness students preferred clinical medicine to basic medicine (p=0.010) and more Openness students preferred medical departments to others (p=0.031). Personal interest was the significant motivational factors in more Openness students (p=0.003) and Conscientiousness students (p=0.003). Medical students with more Agreeableness were more likely to prefer clinical medicine and those with more Openness preferred medical departments. Personal interest was a significant influential factor determining specialty choice in more Openness and Conscientiousness students. These findings may be helpful to medical educators or career counselors in the specialty choice process.

Objectives To assess the factors, motivations, and nonacademic influences that affected the choice of major among pharmacy and nonpharmacy undergraduate students. Methods A survey was administered to 618 pharmacy and nonpharmacy majors to assess background and motivational factors that may have influenced their choice of major. The sample consisted of freshman and sophomore students enrolled in a required speech course. Results African-American and Hispanic students were less likely to choose pharmacy as a major than Caucasians, whereas Asian-Americans were more likely to choose pharmacy as a major. Pharmacy students were more likely to be interested in science and math than nonpharmacy students. Conclusion Students' self-reported racial/ethnic backgrounds influence their decision of whether to choose pharmacy as their academic major. Results of this survey provide further insight into developing effective recruiting strategies and enhancing the marketing efforts of academic institutions. PMID:20498739

2016-11-01

To 1) describe patterns of specialty choice; 2) investigate relationships between career selection and selected demographic indicators; and 3) identify salary perception, factors that influence career choice in primary care, and factors that influence desired location of future medical practice. The study used a mixed-methods approach that included a cross-sectional questionnaire survey applied to 234 last-year medical students in Honduras (September 2014), and semi-structured interviews with eight key informants (October 2014). Statistical analysis included chi-square and factor analysis. An alpha level of 0.05 was used to determine significance. In the qualitative analysis, several codes were associated with each other, and five major themes emerged. Primary care careers were the preferred choice for 8.1% of students, who preferred urban settings for future practice location. The perceived salary of specialties other than primary care was significantly higher than those of general practitioners, family practitioners, and pediatricians (P < 0.001). Participants considered "making a difference," income, teaching, prestige, and challenging work the most important factors influencing career choice. Practice in ambulatory settings was significantly associated with a preference for primary care specialties (P = < 0.05). Logistic regression analysis found that factors related to patient-based care were statistically significant for selecting primary care (P = 0.006). The qualitative analysis further endorsed the survey findings, identifying additional factors that influence career choice (future work option; availability of residency positions; and social factors, including violence). Rationales behind preference of a specialty appeared to be based on a combination of ambition and prestige, and on personal and altruistic considerations. Most factors that influence primary care career choice are similar to those found in the literature. There are several factors

To identify factors that influence specialty choice among Wisconsin medical students and provide insight into approaches to encourage more students to pursue careers in primary care. The importance of several factors in medical student career choice was surveyed using a Web survey convenience sample of all Wisconsin medical students. Students intending to pursue a career in primary care and in other specialties were compared. Respondents, regardless of specialty choice or gender, identified a similar group of factors as highly influential, and similar group of factors as non-influential in their decision-making. However, significantly more primary care students than other specialty students considered interest in underserved populations, relationships with patients, scope of practice, and role models important in their career choice. Significantly more primary care students than other specialty students responded that salary and competitiveness were "not at all" important. A greater number of other specialty students than primary care students stated that interest in scope of practice, role models, and training years were "not at all" important. Debt-related factors were reported as "not at all" important by nearly one-third of respondents. Although primary care and other specialty students report making their career plans based on the impact of similar factors, significant differences between primary care and other specialty students were reported in key areas. These results validate many previously reported factors, and indicate that salary and years of training may have been overemphasized in understanding student career choice. The results of this survey may be useful for Wisconsin medical schools in order to sustain, support, and foster student interest in primary care.

We explored with Aboriginal adults living in a remote Australian community the social context of food choice and factors perceived to shape food choice. An ethnographic approach of prolonged community engagement over 3 years was augmented by interviews. Our findings revealed that knowledge, health, and resources supporting food choice were considered "out of balance," and this imbalance was seen to manifest in a Western-imposed diet lacking variety and overrelying on familiar staples. Participants felt ill-equipped to emulate the traditional pattern of knowledge transfer through passing food-related wisdom to younger generations. The traditional food system was considered key to providing the framework for learning about the contemporary food environment. Practitioners seeking to improve diet and health outcomes for this population should attend to past and present contexts of food in nutrition education, support the educative role of caregivers, address the high cost of food, and support access to traditional foods.

To establish factors that affect food choices among adolescents living in rural areas and to identify their food choices. A random sample of adolescents living in a Greek rural area (n=382) aged 12-18 years were individually interviewed. Food consumption was assessed by a semi-quantitative food-frequency questionnaire and adherence to the Mediterranean diet was evaluated using the KIDMED questionnaire. Information was collected regarding self-perceived body size, dieting, dietary knowledge, parental control, meal and snack frequency, eating out of home, eating takeaways and precooked meals, eating from the school canteen. Body image concerns, dieting, education about food, parental control, maternal education level and eating with family and peers are factors that were found to affect food choices in this group of Greek adolescents. The adherence to the Mediterranean diet was low (KIDMED index was 4.5±2.7). Regular family meals at home were frequent in this group and 99% of the adolescents ate lunch daily at home. Eating out with peers and eating from the school canteen was related with higher consumption of 'junk type of food'. Girls and younger adolescents and those whose mothers had a higher education level seem to make healthier choices. Factors such as personal issues, family and peer pressure significantly affect food choices among adolescents living in a Greek rural area and highlight the importance of implementing multilevel strategies to promote healthy eating among adolescents.

The aim of this study was to investigate factors influencing career choices in radiology trainees. We distributed a 27-question written survey to all radiology registrars in Queensland. The questions investigated whether radiology was their first specialty choice, career satisfaction, ideal working conditions and attitudes regarding having children during the time of training. Forty-four of 51 surveys were returned (86% participation rate, 73% men, P = 0.048055) with 100% reporting a high job satisfaction; 28% of male registrars compared to 8% of female registrars did extra work outside of training to earn extra money (P = 0.000003), and 17% of female registrars took a leave of absence during their training, while no male registrar did (P = 0.087923). Only one female trainee worked part-time (P = 0.272727). In addition, 58% of female registrars planned a pregnancy (P = 0.731789) before completion of training; 83% of women versus 75% of men had no children (P = 0.329263). Only 5% of trainees agreed that it was easy to arrange part-time training, only 14% stated that it was easy to negotiate flexible work schedules and 7% agreed that it was easy to return to work after a period of absence. 'Time spent with immediate family' was rated the most important lifestyle factor, followed by 'work hours' and 'on-call duty'. The least important factors were 'being away from extended family', 'availability of part-time work' and whether 'work was in a rural location'. Overall job satisfaction is high among radiology trainees. Nevertheless, lifestyle factors, particularly those related to work time, are becoming more important for career decisions. This should be taken into account when designing and structuring radiology training to ensure that it is considered an attractive career choice.

Up to 35% of the population modify their diet for adverse reactions to food. This study described the food choice behaviour of diagnosed food-allergic (DFA), self-reported food-allergic or intolerant (SFA) and nonfood-allergic (NFA) consumers, and explored differences between them. Six focus groups with adults (n = 44) were conducted. Data analysis was performed using thematic content analysis. Compared to NFA participants, DFA consumers were deprived of satisfaction and pleasure from foods, experienced difficulties finding safe foods and had to be organized with eating. SFA participants faced similar problems, but to a lesser degree; their food choices were strongly influenced by emotional factors or health awareness. Food-allergic consumers' food choices are influenced by a number of factors that differ to those of NFA consumers. It is therefore important to offer people with food allergies or intolerances advice that goes beyond how to avoid allergens. © 2012 John Wiley & Sons A/S.

Nutrition is an essential component in promoting health and quality of life into the older adults years. The purpose of this qualitative research is to explore how the rural food environment influences food choices of older adults. Four focus groups were conducted with 33 older adults (50 years of age and older) residing in rural Montana communities. Four major themes related to factors influencing food choices among rural older adults emerged from this study: perception of the rural community environment, support as a means of increasing food access, personal access to food sources, and dietary factors. The findings from this current study warrant further research and promotion of specifically tailored approaches that influence the food choices of older adults in the rural western USA, including the developing and expanding public transportation systems, increasing availability of local grocers with quality and affordable food options, increasing awareness and decreasing stigma surrounding community food programs, and increasing nutrition education targeting senior health issues.

When choosing their sleeping sites, primates make adaptive trade-offs between various biotic and abiotic constraints. In human-modified environments, anthropic factors may play a role. We assessed the influence of ecological (predation), social (intergroup competition), and anthropic (proximity to human settlements) factors in sleeping site choice by long-tailed macaques (Macaca fascicularis) occupying a habitat at the interface of natural forests and human-modified zones in Bali Barat National Park, Indonesia. Over the course of 56 nights, we collected data relating to physical features of sleeping trees, patterns of the use of sleeping sites within the home range, pre-sleep behavior, diurnal ranging patterns and availability of natural and human food. Overall, the macaques used 17 sleeping sites with 37 sleeping trees. When the monkeys slept in forest zones, they selected sleeping trees that had larger trunks but were not significantly taller than surrounding trees. Though the macaques rarely re-used sleeping sites on consecutive nights, they frequently re-used four sites over the study period. The group favored sleeping within the core area of its home range, despite the occurrence of frequent agonistic intergroup encounters there. Macaques preferentially selected sleeping trees located within or near human-modified zones, especially when human food was abundant and natural food was scarce. These results partially support the hypothesis that long-tailed macaques choose their sleeping sites to avoid predation; proximity to human settlements appears to be the primary factor influencing sleeping site choice in this primate species. Our results reflect the strong influence that anthropic factors have on primates, which subsist in increasingly human-dominated landscapes. © 2014 Wiley Periodicals, Inc.

Objective This article critically appraises the range of personal, professional and social factors that affect the choice of speciality across medical students, prevocational doctors, general practice registrars and general practitioners. Methods This qualitative study applied constructs from the fields of decision theory and career theory to better understand the complex nature of choosing a speciality. In all, 47 in-depth interviews were conducted with participants at different stages of their career cycle. The data was codified and analysed using NVivo to identify key factors that influenced speciality choice. Results The research identified 77 individual findings influencing general practice as a choice of medical speciality. These were distilled into a matrix to show that factors such as money, prestige and peer interaction did not have a compelling effect, whereas clinical and academic role models, flexibility, work-life balance, scope of practice, connection with patients, training environment and practical opportunities did. Conclusion The findings indicate that the decision in relation to the choice of medical speciality is a complex cognitive process that is undertaken within a personal, social and professional context particular to each individual. What is known about the topic? Current literature aims to quantify changes in attitudes towards choice of speciality or the effect of particular variables in isolation while ignoring the complexity of this decision process and how the numerous variables compare with each other. What does this paper add? The present study is the first intergenerational research on this topic in the Australian context and the paper dismisses the role of prestige and remuneration as key drivers of choice in picking general practice as a speciality, noting that money is merely a 'hygiene factor'. What are the implications for policy makers? A policy framework outlining 10 key principles is presented to assist policy makers seeking

Although stress reaction is high among nursing staff and nursing students in the Middle East and its effect on life is known, there are scant studies reporting on these clinical and social features. In addition, there are no studies reporting on factors that influence career choice among this group. This study aimed to investigate factors that influence career choice among nursing students and their possible association with depressive symptoms. Participants were 150 (84.7% response rate) nursing students randomly selected from each academic year at the Nursing College/Jordan University of Science and Technology. Participants consented and completed the socio-demographic data collection sheet. The Arabic version of the Beck Depression Inventory-II Scale was used to assess participants with respect to depressive symptoms. A modified list of factors influencing career choice and a Likert scale to assess the level of sadness and the degree of religiosity were used as well. Students ranked the most important three factors influencing their career selection as family decision, religious factors, and the desire to care for others. The prevalence of depression among the sample was 26%. Students who had a desire to care for others were less likely to suffer from depression and those who chose nursing as their career due to religious factors were significantly less depressed than those who did not. Meanwhile, students who chose nursing under family pressure or because of a lack of alternative opportunities were more depressed. The odds ratio for depressive symptoms was 0.24 when students chose nursing because of religious factors, whereas it was 4.92 when the family strongly influenced the student's career decision and 3.61 when a nursing career was the only perceived opportunity available. The main factors associated with depression among this sample of nursing students were pressure from their family to choose a nursing career and having no other career or employment

There is growing interest in the usefulness of the workplace as a site for promotion of healthful food choices. The authors therefore analyzed data of U.S. adults (N = 1,918) who reported working outside the home and eating lunch. The majority (84.0%) of workers had a break room. About one half (54.0%) purchased lunch > or = 2 times/week, with higher percentages for males, Blacks, younger (age 18-34 years) versus older adults (age 55 years or older), and obese versus normal-weight persons. The most important lunch food choice value was convenience (34.3%), followed by taste (27.8%), cost (20.8%), and health (17.1%). The typical source for purchasing lunch was a fast-food restaurant (43.4%), followed by on-site cafeteria/snack shop (25.3%), full-service restaurant (16.9%), supermarket (5.2%), vending machine (4.4%), and convenience store (4.0%); younger adults and those less educated relied more on fast-food places. This study identifies individual factors and values that may influence future dietary health initiatives in the work site.

Growth dominates choice in network percolation

2013-09-01

The onset of large-scale connectivity in a network (i.e., percolation) often has a major impact on the function of the system. Traditionally, graph percolation is analyzed by adding edges to a fixed set of initially isolated nodes. Several years ago, it was shown that adding nodes as well as edges to the graph can yield an infinite order transition, which is much smoother than the traditional second-order transition. More recently, it was shown that adding edges via a competitive process to a fixed set of initially isolated nodes can lead to a delayed, extremely abrupt percolation transition with a significant jump in large but finite systems. Here we analyze a process that combines both node arrival and edge competition. If started from a small collection of seed nodes, we show that the impact of node arrival dominates: although we can significantly delay percolation, the transition is of infinite order. Thus, node arrival can mitigate the trade-off between delay and abruptness that is characteristic of explosive percolation transitions. This realization may inspire new design rules where network growth can temper the effects of delay, creating opportunities for network intervention and control.

Which factors decided general practitioners’ choice of hospital on behalf of their patients in an area with free choice of public hospital? A questionnaire study

PubMed Central

2012-01-01

Background Parts of New Public Management-reforms of the public sector depend on introduction of market-like mechanisms to manage the sector, like free choice of hospital. However, patients may delegate the choice of hospital to agents like general practitioners (GPs). We have investigated which factors Danish GPs reported as decisive for their choice of hospital on behalf of patients, and their utilisation of formal and informal data sources when they chose a hospital on behalf of patients. Methods Retrospective questionnaire study of all of the 474 GPs practising in three counties which constituted a single uptake area. Patients were free to choose a hospital in another county in the country. The GPs were asked about responsibility for choice of the latest three patients referred by the GP to hospital; which of 16 factors influenced the choice of hospital; which of 15 sources of information about clinical quality at various hospitals/departments were considered relevant, and how often were six sources of information about waiting time utilised. Results Fifty-one percent (240 GPs) filled in and returned the questionnaire. One hundred and eighty-three GPs (76%) reported that they perceived that they chose the hospital on behalf of the latest referred patient. Short distance to hospital was the most common reason for choice of hospital. The most frequently used source of information about quality at hospital departments was anecdotal reports from patients referred previously, and the most important source of information about waiting time was the hospitals’ letters of confirmation of referrals. Conclusions In an area with free choice of public hospital most GPs perceived that they chose the hospital on behalf of patients. Short distance to hospital was the factor which most often decided the GPs’ choice of hospital on behalf of patients. GPs attached little weight to official information on quality and service (waiting time) at hospitals or departments, focusing

Key Factors Influencing Rapid Development of Potentially Dune-Stabilizing Moss-Dominated Crusts

Biological soil crusts (BSCs) are a widespread photosynthetic ground cover in arid and semiarid areas. They have many positive ecological functions, such as increasing soil stability, and reducing water and wind erosion. Using artificial technology to achieve the rapid development of BSCs is expected to become a low-cost and highly beneficial ecological restoration measure. In the present study, typical moss-dominated crusts in a region characterized by mobile dunes (Mu Us Sandland, China) were collected, and a 40-day cultivation experiment was performed to investigate key factors, including watering frequency, light intensity and a nutrient addition, which affect the rapid development of moss crusts and their optimal combination. The results demonstrated that watering frequency and illumination had a significant positive effect (P=0.049, three-factor ANOVA) and a highly significant, complicated effect (P=0.000, three-factor ANOVA), respectively, on the plant density of bryophytes, and a highly significant positive effect on the chlorophyll a and exopolysaccharide contents (P=0.000, P=0.000; P=0.000, P=0.000; one-way ANOVA). Knop nutrient solution did not have a significant positive but rather negative effect on the promotion of moss-dominated crust development (P=0.270, three-factor ANOVA). Moss-dominated crusts treated with the combination of moderate-intensity light (6,000 lx) + high watering frequency (1 watering/2 days) - Knop had the highest moss plant densities, while the treatment with high-intensity light (12,000 lx) + high watering frequency (1 watering/2 days) + Knop nutrient solution had higher chlorophyll a contents than that under other treatments. It is entirely feasible to achieve the rapid development of moss crusts under laboratory conditions by regulating key factors and creating the right environment. Future applications may seek to use cultured bryophytes to control erosion in vulnerable areas with urgent needs. PMID:26230324

The social dominance paradox.

Cook, Jennifer Louise; den Ouden, Hanneke E M; Heyes, Cecilia M; Cools, Roshan

2014-12-01

Dominant individuals report high levels of self-sufficiency, self-esteem, and authoritarianism. The lay stereotype suggests that such individuals ignore information from others, preferring to make their own choices. However, the nonhuman animal literature presents a conflicting view, suggesting that dominant individuals are avid social learners, whereas subordinates focus on learning from private experience. Whether dominant humans are best characterized by the lay stereotype or the animal view is currently unknown. Here, we present a "social dominance paradox": using self-report scales and computerized tasks, we demonstrate that socially dominant people explicitly value independence, but, paradoxically, in a complex decision-making task, they show an enhanced reliance (relative to subordinate individuals) on social learning. More specifically, socially dominant people employed a strategy of copying other agents when the agents' responses had a history of being correct. However, in humans, two subtypes of dominance have been identified: aggressive and social. Aggressively dominant individuals, who are as likely to "get their own way" as socially dominant individuals but who do so through the use of aggressive or Machiavellian tactics, did not use social information, even when it was beneficial to do so. This paper presents the first study of dominance and social learning in humans and challenges the lay stereotype in which all dominant individuals ignore others' views. The more subtle perspective we offer could have important implications for decision making in both the boardroom and the classroom. Copyright © 2014 Elsevier Ltd. All rights reserved.

Dominant factors in controlling marine gas pools in South China

Xu, S.; Watney, W.L.

2007-01-01

In marine strata from Sinian to Middle Triassic in South China, there develop four sets of regional and six sets of local source rocks, and ten sets of reservoir rocks. The occurrence of four main formation periods in association with five main reconstruction periods, results in a secondary origin for the most marine gas pools in South China. To improve the understanding of marine gas pools in South China with severely deformed geological background, the dominant control factors are discussed in this paper. The fluid sources, including the gas cracked from crude oil, the gas dissolved in water, the gas of inorganic origin, hydrocarbons generated during the second phase, and the mixed pool fluid source, were the most significant control factors of the types and the development stage of pools. The period of the pool formation and the reconstruction controlled the pool evolution and the distribution on a regional scale. Owing to the multiple periods of the pool formation and the reconstruction, the distribution of marine gas pools was complex both in space and in time, and the gas in the pools is heterogeneous. Pool elements, such as preservation conditions, traps and migration paths, and reservoir rocks and facies, also served as important control factors to marine gas pools in South China. Especially, the preservation conditions played a key role in maintaining marine oil and gas accumulations on a regional or local scale. According to several dominant control factors of a pool, the pool-controlling model can be constructed. As an example, the pool-controlling model of Sinian gas pool in Weiyuan gas field in Sichuan basin was summed up. ?? Higher Education Press and Springer-Verlag 2007.

Internationally, and particularly in Singapore, health education institutions are facing challenges in attracting school leavers to enter nursing courses. To identify the factors influencing the career choice of Singaporean healthcare students and determine the deterrents in choosing nursing as a career choice. An exploratory descriptive qualitative study design was used. Fifty-nine healthcare students from three higher education institutions were recruited. Four nursing and four non-nursing focus groups discussion were held. Interview transcripts were analysed using thematic analysis. Six themes emerged as follows: 'personal interest'; 'prior healthcare exposure'; 'job prospects'; 'academic performance'; 'perceived nature of work'; and 'social influences'. The personal interests to help and care along with prior healthcare exposures were found to influence the students' choice. Job prospects such as the ease of getting a job, job stability, and job salary were considered. Nursing was perceived as a course for students with poor academic ability. Misconceptions about the nature of work and a lack of social recognition were identified as deterring factors in students' choice of nursing as a career. An understanding of the career decision process among healthcare students enables educational leaders and policy-makers to enhance the focus of nursing recruitment strategies. Strategies for nursing recruitment in Singapore must include creating more opportunities for exposure to nursing in early school years, reviewing the admission policies for nursing programmes to attract academically abled students, ensuring that nursing graduates' salaries are comparable with other healthcare graduates, promoting a better understanding on the role of a registered nurse and its career developments, and providing support for those who are interested in nursing but are faced with career decision-making difficulties due to their families. © 2016 International Council of Nurses.

A global shortage of healthcare professionals calls for effective recruitment and retention strategies. The nursing profession faces greater staffing shortages compared with other healthcare professions. Identifying these factors for choosing a career in health care is an important step in structuring future nursing recruitment strategies. This systematic review examined the motivations for choosing a career in health care, then compared them to factors that influence the choice to pursue a career in nursing. A literature search of the CINAHL, PubMed, Web of Science and Scopus databases for articles published between 2002 and 2013 was conducted. The search included studies that focused on factors influencing career choice among undergraduate medicine, dentistry, pharmacy and nursing students. A total of 29 papers were included in the review. The themes and subthemes that emerged from this review included: (1) intrinsic factors, including a desire to help others and a personal interest in health care, (2) extrinsic factors, such as financial remuneration, job security, professional prestige and job autonomy, (3) socio-demographic factors such as gender and socio-economic status, and (4) interpersonal factors, encompassing the influence of family and other professional individuals. Healthcare professionals were generally motivated by intrinsic factors. However, public perceptions of nursing as a low-paying and low-status job have significantly hindered the participants' choice to pursue it as a career. Nursing institutions could provide more platforms to help school leavers better understand the nursing career. In turn, hospital administrators could invite parents to nursing career fairs, increase financial remuneration for nurses, and provide decision-making avenues aimed at recruiting and retaining more nurses. © 2015 International Council of Nurses.

In group-living animals, individuals do not interact uniformly with their conspecifics. Among primates, such heterogeneity in partner choice can be discerned from affiliative grooming patterns. While the preference for selecting close kin as grooming partners is ubiquitous across the primate order, the selection of higher-ranking non-kin individuals as grooming partners is less common. We studied a group of provisioned rhesus macaques (Macaca mulatta brevicaudus) on Hainan Island, China, to examine rank-related benefits of grooming exchanges and the influence of kin relationships. We tested four hypotheses based on Seyfarth's model: (1) there will be kin preference in grooming relationships; (2) grooming between non-kin individuals will be directed up the dominance rank; (3) grooming between non-kin individuals will reduce aggression from higher-ranking ones; and (4) non-kin individuals will spend more time grooming with adjacent ranked ones. We found that grooming relationships between kin individuals were stronger than those between non-kin individuals. For non-kin relationships, lower-ranking individuals received less aggression from higher-ranking ones through grooming; a benefit they could not derive through grooming exchanges with individuals related by kinship. Individuals spent more time grooming adjacent higher-ranking non-kin individuals and higher-ranking individuals also received more grooming from non-kin individuals. Our results supported Seyfarth's model for predicting partner choice between non-kin individuals. For relationships between kin individuals, we found results that were not consistent with prediction for the exchanges of aggression and grooming, indicating the importance to control for the influence of kinship in future studies.

Background In Germany, there is a shortage of young physicians in several specialties, the situation of general practitioners (GP) being especially precarious. The factors influencing the career choice of German medical students are poorly understood. This study aims to identify factors influencing medical students' specialty choice laying a special focus on general practice. Methods The study was designed as a cross-sectional survey. In 2010, students at the five medical schools in the federal state of Baden-Wuerttemberg (Germany) filled out an online-questionnaire. On 27 items with 5-point Likert scales, the students rated the importance of specified individual and occupational aspects. Furthermore, students were asked to assign their intended medical specialty. Results 1,299 students participated in the survey. Thereof, 1,114 students stated a current choice for a specialty, with 708 students choosing a career in one of the following 6 specialties: internal medicine, surgery, gynaecology and obstetrics, paediatrics, anaesthetics and general practice. Overall, individual aspects ('Personal ambition', 'Future perspective', 'Work-life balance') were rated as more important than occupational aspects (i.e. 'Variety in job', 'Job-related ambition') for career choice. For students favouring a career as a GP individual aspects and the factor 'Patient orientation' among the occupational aspects were significantly more important and 'Job-related ambition' less important compared to students with other specialty choices. Conclusions This study confirms that future GPs differ from students intending to choose other specialties particularly in terms of patient-orientation and individual aspects such as personal ambition, future perspective and work-life balance. Improving job-conditions in terms of family compatibility and work-life balance could help to increase the attractiveness of general practice. Due to the shortage of GPs those factors should be made explicit at an

Postgraduate medical education in Singapore underwent major transition recently, from a British-style system and accreditation to a competency-based residency programme modelled after the American system. We aimed to identify the relative importance of factors influencing the choice of residency sponsoring institutions (SIs) among medical students during this transition period. A questionnaire-based cross-sectional study of Singaporean undergraduate medical students across all years of study was performed in 2011. Participants rated 45 factors (including research, academia and education, marketing, reputation of faculty, working conditions, posting experience and influence by peers/seniors) for degree of importance to their choice of SIs on a five-point Likert scale. Differences with respect to gender and seniority were compared. 705 of 1,274 students completed the survey (response rate 55.3%). The top five influencing factors were guidance by mentor (4.48 ± 0.74), reputation for good teaching (4.46 ± 0.76), personal overall experience in SIs (4.41 ± 0.88), quality of mentorship and supervision (4.41 ± 0.75), and quality and quantity of teaching (4.37 ± 0.78). The five lowest-rated factors were social networking (2.91 ± 1.00), SI security (3.01 ± 1.07), open house impact (3.15 ± 0.96), advertising paraphernalia (3.17 ± 0.95) and research publications (3.21 ± 1.00). Female students attributed more importance to security and positive work environment. Preclinical students rated research and marketing aspects more highly while clinical students valued positive work environment more. Quality of education, mentorship, experiences during clerkship and positive working environment were the most important factors influencing the choice of SIs.

This paper reports on factors influencing the decision of mothers regarding the type of feeding method for their babies in a rural setting in Cameroon. The aim of the study was to ascertain the proportion of mothers choosing the different methods of feeding, to determine the various factors influencing their choices, and to ascertain the relationships of these factors to their respective choices. Questionnaires were used on 108 HIV-positive mothers who had delivered babies and who were administered nevirapine at least 3 months prior to the study. A focus group discussion with mothers also took place. Findings were that more mothers (84%) chose breastfeeding than artificial feeding (16%), while a minority (4%) selected mixed feeding. Factors found to militate against artificial feeding were cost (69%), stigma (64%), family pressure (44%), inconvenience in preparation/administration (38%), prior education from health workers (23%), and loss of special attention from family (8%). On the other hand, advice of health worker (44%), ill health (19.5%), free milk (12.5%),job pressure (12.5%) and loss of beauty (12.5%) were found to militate against breastfeeding. A direct relationship was also found between age, educational level, income size, marital status and choice of feeding. Policies targeting stigma reduction and socio-cultural factors affecting the choice of feeding are needed to optimise uptake of the less risky methods of feeding which could in turn contribute to a reduction in transmission.

Background In Japan, there is a shortage of young physicians in various specialties; the present situation of general medicine or family medicine (GM/FM) in particular is risky. The factors influencing the career choice of Japanese medical students are poorly understood. This study aims to identify factors related to choosing GM/FM as a career. Methods The study was designed as a cross-sectional survey. Students at one medical school in Japan filled out a questionnaire. Students were asked to state their intended medical specialty, and they rated the importance of specific individual and occupational aspects using a 4-point likert scale. Factor analysis was performed on the variables. Reliability of the factor scores was estimated using Cronbach‘s alpha coefficients; biserial correlations between the factors and career choices were calculated. Furthermore, multiple linear regression analysis was performed using career choice (GM/FM vs. others) as the criterion variable and the factors plus demographic characteristics as confounding variables. Results Factor analysis produced six factors that explained future career plans. Medical students in this study had a positive and realistic idea about GM/FM, but only 18.8% of them chose GM/FM first as a career. The significant variables associated with choosing GM/FM first as a career were: ‘Admission from hometown’ (β=0.189, P=0.001), ‘Student preparing for the entrance exam’ (β=0.172; P=0.001), ‘Intent for rural practice’ (β=0.123, P=0.016), and ‘Work–life balance’ (β=0.126, P=0.013). While significant variables that were negatively associated with choosing GM/FM were ‘Presence of medical relatives’ (β=−0.107, P=0.037) and ‘Scientific orientation’ (β=−0.125, P=0.013). Conclusions Strategies have been suggested, such as recruiting medical students with significant variables that were associated with choosing GM/FM first as a career.

Constructing food choice decisions.

PubMed

Sobal, Jeffery; Bisogni, Carole A

2009-12-01

Food choice decisions are frequent, multifaceted, situational, dynamic, and complex and lead to food behaviors where people acquire, prepare, serve, give away, store, eat, and clean up. Many disciplines and fields examine decision making. Several classes of theories are applicable to food decision making, including social behavior, social facts, and social definition perspectives. Each offers some insights but also makes limiting assumptions that prevent fully explaining food choice decisions. We used constructionist social definition perspectives to inductively develop a food choice process model that organizes a broad scope of factors and dynamics involved in food behaviors. This food choice process model includes (1) life course events and experiences that establish a food choice trajectory through transitions, turning points, timing, and contexts; (2) influences on food choices that include cultural ideals, personal factors, resources, social factors, and present contexts; and (3) a personal system that develops food choice values, negotiates and balances values, classifies foods and situations, and forms/revises food choice strategies, scripts, and routines. The parts of the model dynamically interact to make food choice decisions leading to food behaviors. No single theory can fully explain decision making in food behavior. Multiple perspectives are needed, including constructionist thinking.

Optometry is only provided at tertiary level in two institutions in Ghana, with an average of 50 students graduating each year for a population of approximately 24.6 million. No information on the demography of optometry students and factors that influence their choice of optometry as a career and institution of learning is available. This information is important as it will assist optometry institutions to formulate effective student recruitment strategies. To assess the demographic characteristics of Ghanaian optometry students, the factors that influence their selection of optometry as a career and institution of learning. We conducted a cross sectional study among Ghanaian optometry students using a structured questionnaire to collect data on the demographic characteristics and factors that might influence their choice of optometry as a career as well as choice of institution of learning. Two hundred and eighty students from the two optometry training institutions in Ghana; University of Cape Coast (48.2%) and Kwame Nkrumah University of Science and Technology (51.8%) responded to the questionnaire. Their ages ranged from 17 to 28 years with most being males (72.5%), and the majority (79%) being from urban areas. The main factors that influenced their career choice were job availability after graduation (90%) and desire to help other people (89.2%). Factors that influenced their institution choice were preference for an institution (36.8%) and proximity to home (24.4%). In the absence of adequate optometry jobs in the public health sector, women will remain marginalised specifically those in rural areas. This marginalisation is however, a reflection of a broader societal disadvantage for women. Greater effort needs to be made to recruit high school students from rural areas to study optometry and more institutions need to provide optometry instruction throughout the country.

To increase understanding of disabled and chronically ill people's experiences of revisiting choices by considering events that prompted people to reconsider choices; what factors motivated them to act upon these events and what factors affected their experiences of revisiting choices. A sub-sample of 20 disabled and chronically ill people who took part in a qualitative, longitudinal study exploring choice-making in the context of changing circumstances. Each person was interviewed three times. Analysis focussed on choices that people had been prompted to revisit. Most choices were about health or social care and were revisited within a year due to: changes in health or social circumstances; poorer than expected outcomes; and external interventions. People were motivated to make changes by a desire to maintain independence and control, but perceived short-term costs of decision-making could act as a deterrent. Experiences of revisiting choices were affected by help from other people and emotional strength. Making and revisiting choices is complex; people need support to engage with the continual cycle of choice-making. People who instigate revisions of their own accord may be particularly vulnerable to lack of support.

Swiss primary care (PC) is facing workforce shortage. Up to 2011 this workforce was supplied by two board certifications: general medicine and internal medicine. To strengthen them against subspecialties, they were unified into one: general internal medicine. However, since unification general practitioners' career options are no longer restrained by early commitment to PC. This may lead to a decrease of future primary care physicians (PCPs). To gain insights in timing and factors influencing career choice of internists, we addressed a cross sectional survey to all board certified internists in the years 2000-2010 (n = 1462). Main measures were: final career choice (PCPs, hospital internists or subspecialists), timing and factors influencing career choice, and attractiveness of PCP career during medical school and residency. Response rate was 53.2%, 44.8% were female and median age was 45 years old. Final career choice was PCP for 39.1% of participants, 15.0% chose to become hospital internists, 41.8% became subspecialists and 4.0% other. Timing of career choice significantly differed between groups. Most of the subspecialists have chosen their career during residency (65.3%), while only 21.9% of the PCPs chose during residency. Work experience in an academic hospital was negatively associated with becoming PCP (P < 0.001). Family influence on career choice was more frequently reported among PCPs and chiefs' influence more reported among non-PCPs (P < 0.001). Fifty-nine percent of the participants considered a career as PCP to be attractive during medical school, this proportion decreased over time. Timing of career choice of PCPs and subspecialists strongly differed. PCPs opted late for their career and potentially modifiable external factors seem to contribute to their decision. This stresses the importance of fostering attractiveness of PC during medical school as well as during and after residency and of tailored residency positions for future PCPs

Domain-specific rationality in human choices: violations of utility axioms and social contexts.

PubMed

Wang, X T

1996-07-01

This study presents a domain-specific view of human decision rationality. It explores social and ecological domain-specific psychological mechanisms underlying choice biases and violations of utility axioms. Results from both the USA and China revealed a social group domain-specific choice pattern. The irrational preference reversal in a hypothetical life-death decision problem (a classical example of framing effects) was eliminated by providing a small group or family context in which most subjects favored a risky choice option regardless of the positive/negative framing of choice outcomes. The risk preference data also indicate that the subjective scope of small group domain is larger for Chinese subjects, suggesting that human choice mechanisms are sensitive to culturally specific features of group living. A further experiment provided evidence that perceived fairness might be one major factor regulating the choice preferences found in small group (kith-and-kin) contexts. Finally, the violation of the stochastic dominance axiom of the rational theory of choice was predicted and tested. The violations were found only when the "life-death" problem was presented in small group contexts; the strongest violation was found in a family context. These results suggest that human decisions and choices are regulated by domain-specific choice mechanisms designed to solve evolutionary recurrent and adaptively important problems.

Dominant climatic factors driving annual runoff changes at the catchment scale across China

With global climate changes intensifying, the hydrological response to climate changes has attracted more attention. It is beneficial not only for hydrology and ecology but also for water resource planning and management to understand the impact of climate change on runoff. In addition, there are large spatial variations in climate type and geographic characteristics across China. To gain a better understanding of the spatial variation of the response of runoff to changes in climatic factors and to detect the dominant climatic factors driving changes in annual runoff, we chose the climate elasticity method proposed by Yang and Yang (2011). It is shown that, in most catchments of China, increasing air temperature and relative humidity have negative impacts on runoff, while declining net radiation and wind speed have positive impacts on runoff, which slow the overall decline in runoff. The dominant climatic factors driving annual runoff are precipitation in most parts of China, net radiation mainly in some catchments of southern China, air temperature and wind speed mainly in some catchments in northern China.

Requests for elective cesarean delivery (ECD) have increased in Iran. While some sociodemographic and fear-related factors have been linked with this choice, psychological factors such as self-esteem, stress, and health beliefs are under-researched. A total of 342 primigravidae (mean age = 25 years) completed questionnaires covering psychological dimensions such as self-esteem, perceived stress, marital relationship quality, perceived social support, and relevant health-related beliefs. Of the sample, 214 (62.6%) chose to undergo ECD rather than vaginal delivery (VD). This choice was associated with lower self-esteem, greater perceived stress, belief in higher susceptibility to problematic birth and barriers to an easy birth, along with lower perceived severity of ECD, fewer perceived benefits from VD, lower self-efficacy and a lower feeling of preparedness. No differences were found for marital relationship quality or perceived social support. The pattern suggests that various psychological factors such as self-esteem, self-efficacy, and perceived stress underpin the decision by primigravidae to have an ECD.

The aim of this study was to survey ten graduating classes at Harvard School of Dental Medicine regarding students' specialty choice and factors influencing that choice. Students were surveyed once in 2008 (for the Classes of 2007-11) and again in 2013 (for the Classes of 2012-16). A prior article reported results regarding students' interest in and experiences with prosthodontics; this article presents results regarding their interest in all dental specialties and factors influencing those interests. Of a total 176 students in the Classes of 2012-16, 143 responded to the survey, for a response rate of 81%, compared to a 95% response rate (167 of total 176 students) for the Classes of 2007-11. The results showed that orthodontics was the most popular specialty choice, followed by oral and maxillofacial surgery. From the 2008 to the 2013 survey groups, there was an increase in the percentages of students planning to pursue oral and maxillofacial surgery, pediatric dentistry, and postdoctoral general dentistry. The educational debt these students expected to accrue by graduation also increased. The largest percentage of students chose "enjoyment of providing the specialty service" as the factor most influencing their specialty choice. "Prior dental school experience" and "faculty influence" were greater influences for students pursuing specialties than those pursuing postdoctoral general dentistry. Increased interest in particular disciplines may be driven by high debt burdens students face upon graduation. Factors related to mentoring especially influenced students pursuing specialties, demonstrating the importance of student experiences outside direct patient care for exposure to the work of specialists beyond the scope of predoctoral training. This finding suggests that dental schools should increase mentoring efforts to help students make career decisions based not on financial burden but rather on personal interest in the specialty, which is likely to have a

The goals of this study were to 1) evaluate dental students' perceptions of dental specialties, 2) identify factors that play an important role in students' decision to pursue specialty training or career choices, and 3) establish a baseline of students' perceptions of the dental fields with the best future in terms of salary, personal and patient quality of life, and overall impact on the dental profession. Surveys were distributed to 494 students at the University of Pennsylvania School of Dental Medicine. Data were collected from 380 traditional four-year students and thirty advanced standing students. Chi-square tests, multivariate analysis, and logistic regressions were used to determine associations and independent contributions of student demographics to their perceptions of dental specialties and factors influencing specialty training or career choices. Debt was a statistically significant factor (p<0.001) in choosing specialty training or career independent of gender, age, or class year. Enjoyment of providing care in a specialty or field was identified as the single most important factor in choosing a specialty career. Half of the respondents had decided not to specialize. Pursuing postdoctoral general dentistry training and private practice in general dentistry were the most commonly reported plans after completion of dental school. Suggestions are made for ways to inform students about specialty training.

Language choice in bimodal bilingual development.

Bilingual children develop sensitivity to the language used by their interlocutors at an early age, reflected in differential use of each language by the child depending on their interlocutor. Factors such as discourse context and relative language dominance in the community may mediate the degree of language differentiation in preschool age children. Bimodal bilingual children, acquiring both a sign language and a spoken language, have an even more complex situation. Their Deaf parents vary considerably in access to the spoken language. Furthermore, in addition to code-mixing and code-switching, they use code-blending-expressions in both speech and sign simultaneously-an option uniquely available to bimodal bilinguals. Code-blending is analogous to code-switching sociolinguistically, but is also a way to communicate without suppressing one language. For adult bimodal bilinguals, complete suppression of the non-selected language is cognitively demanding. We expect that bimodal bilingual children also find suppression difficult, and use blending rather than suppression in some contexts. We also expect relative community language dominance to be a factor in children's language choices. This study analyzes longitudinal spontaneous production data from four bimodal bilingual children and their Deaf and hearing interlocutors. Even at the earliest observations, the children produced more signed utterances with Deaf interlocutors and more speech with hearing interlocutors. However, while three of the four children produced >75% speech alone in speech target sessions, they produced <25% sign alone in sign target sessions. All four produced bimodal utterances in both, but more frequently in the sign sessions, potentially because they find suppression of the dominant language more difficult. Our results indicate that these children are sensitive to the language used by their interlocutors, while showing considerable influence from the dominant community language.

Despite recent developments in post-graduate family medicine training in Japan, the numbers of junior doctors entering family medicine residencies are still limited. The objective of this qualitative study was to investigate the possible factors associated to the career choice of family medicine, especially in the context of the newly established family medicine programs in Japan. From December 2010 to January 2011, we distributed a semi-structured questionnaire about career choice to 58 physician members of the Japan Primary Care Association, and 41 of them responded. Four researchers used the Modified Grounded Theory Approach (Kinoshita, 2003) for three-stage conceptualization. We extracted a conceptual model of the choice of newly established family medicine as a career in Japan, consisting of six categories and 77 subordinate concepts from 330 variations. The subcategories of personal background affecting the family-medicine career choice were characteristics ("self-reliance," "pioneering spirit"), career direction ("community/rural-orientedness," "multifaceted orientation") and experience (e.g., "discomfort with fragmented care"). We divided the influencing factors that were identified for career choice into supporters (e.g., "role model"), conflict of career choice (e.g., "anxiety about diverse/broad practice"), and the dawn of a new era in family medicine in Japan (e.g., "lack of social recognition," "concern about livelihood," and "too few role models"). Although the dawn of a new era seemed a rather negative influencer, it was unique to our study that the dawn itself could attract those with a "pioneering spirit" and an "attitude of self-training." Unlike previous studies, the positive factors such as lifestyle and the short residency program were not shown to be part of family medicine's attractiveness. In contrast, "concern about livelihood" was specific among our respondents and was related to career choice in the dawn period. "Community

Breakfast consumption has been shown to be an important indicator of a healthy lifestyle. Little is known however about factors influencing breakfast consumption and food choices at breakfast in adolescents. The aim of the present study was therefore to describe breakfast habits, and factors influencing food choices at breakfast within the framework of the EU-funded HELENA Study, in 3528 adolescents from ten European cities. Additionally, socio-demographic differences in breakfast habits and in influencing factors were investigated. Half of the adolescents (and fewer girls than boys) indicated being regular breakfast consumers. Girls with mothers with a high level of education, boys from 'traditional' families and boys who perceived low family affluence were positively associated with breakfast consumption. Boys whose parents gave encouragement and girls whose peers ate healthily were more likely to be regular breakfast consumers. 'Hunger', 'taste', 'health concerns' and 'parents or guardian' were the most important influences on the adolescents' food choices at breakfast. Adolescents from southern Europe and girls reported to be more influenced by personal and socio-environmental factors. Socio-demographic differences, in particular regional and gender differences, need to be considered in discussions surrounding the development of nutritional intervention programs intended for adolescents.

To identify factors influencing the decisions of Malaysian first-year pharmacy undergraduate students in private higher education when choosing to pursue a degree in pharmacy as well as their choice of private university. This cross-sectional study employed a validated, self-administered questionnaire which was administered to 543 first-year pharmacy students from nine different private universities. Factor analysis was utilised to extract key factors from the responses. Descriptive and inferential statistics were used to analyse the data. Eight factors motivating students' decision to study pharmacy emerged from the responses, accounting for 63.8% of the variance observed. Students were primarily motivated by intrinsic interests, with work conditions and profession attributes also exerting significant influence. In terms of choice of private university, nine factors were identified, accounting for 73.8% of the variance observed. The image of the school and university were most influential factors in this context, followed by university safety, programme attributes and financial factors. First-year pharmacy students in the private higher education sector are motivated by intrinsic interest when choosing to study pharmacy over other courses, while their choice of private university is influenced primarily by the image of the school and university. © 2017 Royal Pharmaceutical Society.

Although the nutrient requirements and dietary intake of athletes have been thoroughly investigated, little is known about the influences on their food choice, particularly prior to and during competition. This study sought to investigate factors that influence food selection of athletes at two similar international competition events: the Melbourne 2006 and Delhi 2010 Commonwealth Games. A secondary aim was to explore differences in these factors between at each event given the culturally diverse locations. A survey developed for this study was distributed to athletes in the village dining hall at both events. Athletes scored a selection of factors influencing food choice on a scale of 1 (not important) to 5 (very important). A total of 769 individuals completed the questionnaire in total, with 351 (46%) from Delhi and 418 (54%) from Melbourne. Overall, athletes rated nutrient composition (M = 4.22), stage of competition (M = 4.09), time of day (M = 4.02) and familiarity of the food (M = 4.07) higher than sensory properties (smell M = 3.88; visual appearance M = 3.22) when making a food selection. Visual appearance (p = 0.01), stage of competition (p < 0.001) and time of day (p = 0.01) had greater influence in Delhi than Melbourne. Overall, a significantly higher proportion of female athletes rated smell (p < 0.001) and familiar food (p < 0.001) as important compared to males. The stage of competition and nutrition composition was rated as very important by the greatest proportion of athletes from weight category sports (61.9%) and endurance sports (57.9%) respectively. The influence of the coach and team mates was less of an influence than other factors, but more so for athletes from Non-Western regions. Further investigation of the various determinants and motives for food section of athletes from a range of sports and cultures is warranted. Copyright © 2017 Elsevier Ltd. All rights reserved.

Garnham, Laura

2014-01-01

Background The current issue of general practice recruitment is a significant challenge and concern. In order to address this, it is vital to understand medical students' attitudes towards general practice and what influences their choice of intended career. Method We used a questionnaire study to examine these attitudes across all years at Imperial College Medical School and to understand what a group of London medical students' current intended career choices were. Results We found that only 13% of students ranked general practice as their first choice career despite having a generally realistic and positive attitude towards the speciality. They highlighted that the main influence on future career choice was interest in the specific speciality and that lifestyle factors did not seem to be so important. Conclusion Exposure to general practice, primary care research and student GP societies might play some part in increasing interest, but more work is needed to understand why students are rejecting general practice and what we can do collectively to attract students into choosing a career in primary care.

The effect of proximity to a dominant cow on a low-ranking cow's willingness to feed was assessed using choice tests. The main aim of the experiment was to determine the feeding space allowance at which the majority of subordinate cows would choose to feed on high-palatability food (HPF) next to a dominant cow rather than feeding alone on low-palatability food (LPF). Thirty Holstein-Friesian cows were used in the study. Half of the cows were trained to make an association between a black bin and HPF and a white bin and LPF, and the other half were trained with the opposite combination. Observations of pair-wise aggressive interactions were observed during feeding to determine the relative social status of each cow. From this, dominant and subordinate cows were allocated to experimental pairs. When cows had achieved an HPF preference with an 80% success rate in training, they were presented with choices using a Y-maze test apparatus, in which cows were offered choices between feeding on HPF with a dominant cow and feeding on LPF alone. Four different space allowances were tested at the HPF feeder: 0.3, 0.45, 0.6, and 0.75 m. At the 2 smaller space allowances, cows preferred to feed alone (choices between feeding alone or not for 0.3- and 0.45-m tests were significantly different). For the 2 larger space allowances, cows had no significant preferences (number of choices for feeding alone or with a dominant). Given that low-status cows are willing to sacrifice food quality to avoid close contact with a dominant animal, we suggest that the feeding space allowance should be at least 0.6m per cow whenever possible. However, even when space allowances are large, it is clear that some subordinate cows will still prefer to avoid proximity to dominant individuals.

The design of maintenance system and the corresponding logistic support is a very complex process, during which the aim is to find the compromise solutions regarding the relations among different maintenance procedures and the ways of their implementation. As a result of this, various solutions can be adopted, since this is conditioned by a series of important factors and criteria, which can be contradictory sometimes. There are different perspectives on ways of solving practical maintenance problems, that is dilemmas when it comes to the choice of maintenance concept. The principal dilemma is how and when to decide on carrying out maintenance procedures. Should the decision be based on theoretical grounds or experience, how does one reconcile those two extremes, who is to decide upon this? In this article we have offered one, basically new solution as a possibility for maintenance concept choice, based on a significant modification of the widely used failure modes and effects analysis (FMEA) method. This solution is risk-decision factor (RDF). This is a result of seven parameters (of different importance and weight) that have the key impact on the process of production and logistic support. The application of this factor is illustrated by the example of planning, organisation and functioning of the maintenance system applied in The Institute for Manufacturing Banknotes and Coins (ZIN) in Belgrade.

Determinants of farmers' choice for veterinary service providers in Nepal Mountains.

2012-08-01

This study was aimed to analyze factors that affect farmers' choice for major actors of veterinary service providers in village areas of Kaski district of Nepal, with the objective of identifying choice-specific attributes which could be addressed for improving the penetration of professional veterinary services in village areas. The information was obtained from 125 farmers using a structured questionnaire. A proportional hazard model was used for data analysis because of its ability to accommodate the attributes of both the chooser and the choice simultaneously. The results showed that village animal health workers (VAHWs) were the most preferred service providers followed by veterinarians and mid-level technicians. The farmers' age and education level had a significant but inverse relationship with the probability of choosing any of the three service providers. From our study, we found that the main choice-specific attributes with a significant impact on the choice probability was the distance to the preferred service provider. Since there was a high preference for VAHW, this suggests the possibility of poorly trained service providers dominating veterinary service market in village areas of Kaski district. Hence, the efforts put forward in the legalization of VAHW system in Nepal should first address the constraints that obstruct the accessibility of professional veterinary service providers in village areas.

Factors modulating social influence on spatial choice in rats.

Bisbing, Teagan A; Saxon, Marie; Sayde, Justin M; Brown, Michael F

2015-07-01

Three experiments examined the conditions under which the spatial choices of rats searching for food are influenced by the choices made by other rats. Model rats learned a consistent set of baited locations in a 5 × 5 matrix of locations, some of which contained food. In Experiment 1, subject rats could determine the baited locations after choosing 1 location because all of the baited locations were on the same side of the matrix during each trial (the baited side varied over trials). Under these conditions, the social cues provided by the model rats had little or no effect on the choices made by the subject rats. The lack of social influence on choices occurred despite a simultaneous social influence on rats' location in the testing arena (Experiment 2). When the outcome of the subject rats' own choices provided no information about the positions of other baited locations, on the other hand, social cues strongly controlled spatial choices (Experiment 3). These results indicate that social information about the location of food influences spatial choices only when those cues provide valid information that is not redundant with the information provided by other cues. This suggests that social information is learned about, processed, and controls behavior via the same mechanisms as other kinds of stimuli. (c) 2015 APA, all rights reserved).

To assess adolescents' perceptions about factors influencing their food choices and eating behaviors. Data were collected in focus-group discussions. The study population included 141 adolescents in 7th and 10th grade from 2 urban schools in St Paul, Minn, who participated in 21 focus groups. Data were analyzed using qualitative research methodology, specifically, the constant comparative method. Factors perceived as influencing food choices included hunger and food cravings, appeal of food, time considerations of adolescents and parents, convenience of food, food availability, parental influence on eating behaviors (including the culture or religion of the family), benefits of foods (including health), situation-specific factors, mood, body image, habit, cost, media, and vegetarian beliefs. Major barriers to eating more fruits, vegetables, and dairy products and eating fewer high-fat foods included a lack of sense of urgency about personal health in relation to other concerns, and taste preferences for other foods. Suggestions for helping adolescents eat a more healthful diet include making healthful food taste and look better, limiting the availability of unhealthful options, making healthful food more available and convenient, teaching children good eating habits at an early age, and changing social norms to make it "cool" to eat healthfully. The findings suggest that if programs to improve adolescent nutrition are to be effective, they need to address a broad range of factors, in particular environmental factors (e.g., the increased availability and promotion of appealing, convenient foods within homes schools, and restaurants).

2013-08-01

This study analyzed the determinants for choice of animal health providers in a semiarid pastoral area with an aim of identifying specific attributes that could be targeted for intervention to enhance pastoralist access to quality veterinary services. The data were collected through administration of semi-structured questionnaires to 350 randomly selected household heads in different locations in Narok County of Kenya. Most of these respondents had no formal education (66.9%), and most households were headed by men (88.9%). The men were in control of sales (84.2%), purchases (83.7%), and treatment of sick cattle (70.3%), while women were responsible for milking (83.8%). Animal health services were delivered by drug stockists (87.76%) and government veterinarians (12.24%). The time spent while seeking animal health services and transport cost were specific attributes with impact on the probability of choice for service providers. Although distance covered to the preferred service provider was a significant attribute, it was inversely related to the probability of choice. The other factors including herd sizes, age and sex of household head, cost incurred per visit, level of education of household head, and the number of visits did not have significant impact on choices. These findings support commercialization of veterinary services in marginalized areas where the delivery of essential animal health services such as disease control programs are often viewed as a public good. In order to enhance delivery of veterinary services in these areas, it is proposed that public and private means are investigated to support qualified veterinarians and to strengthen the activities of untrained personnel operating drug outlets.

Few studies have examined factors that influence an individual's decision to enter an academic medical career after residency training. We sought to evaluate whether sex, ethnicity, child care issues, and debt burden influenced residents' choice for a career in academic vascular surgery. A 39-item Web survey, designed to elucidate which factors motivated residents to seek a career in academic vascular surgery, was sent to 295 vascular surgery residents currently enrolled in Accreditation Council on Graduate Medical Education-accredited training programs. A total of 128 responses (43%) were received. Of these, 53% of respondents were white and 47% were nonwhite and 34 (27%) were women and 94 (73%) were men. Fifty-seven percent of minorities anticipate a career in academic vascular surgery. There were no statistical differences between sex and ethnicity for factors influencing career choice, including training paradigm, presence of a life partner or dependents, mentorship role, participation in research, service, and teaching, anticipated salary, and debt burden (P > .05). Seventy-seven percent of respondents carry significant debt; of those with debt, 81% owe >$100,000 and 40% owe >$200,000. Seventy-three percent of 0+5 trainees anticipated choosing an academic practice compared with 42% of 5+2 trainees (P < .01). Respondents planning an academic career cited procedural variation, breadth and depth of practice/tertiary referral experience, and research opportunities as the most important drivers of career choice. Income potential, strength of the job market, and child care needs were deemed less important. This study shows that academic vascular surgery is a popular career option for current vascular surgery trainees, especially those in 0+5 programs. Choosing a career in academic vascular surgery appears not to be influenced by sex, ethnicity, child care concerns, salary expectations, or debt burden, even though most trainees carry enormous debt. The data imply

Sexual selection under parental choice: evidence from sixteen historical societies.

PubMed

Apostolou, Menelaos

2012-08-11

Asymmetrical fitness benefits between parents and offspring result in the ideal spouse not being the ideal in-law. This enables parents to attempt to control the mating behavior of their children, and when they succeed, parental choice becomes a primary sexual selection force. A number of studies indicate that parental choice is dominant in contemporary pre-industrial societies. This paper presents evidence from the historical record which indicates that parental choice was also dominant during the later stages of human evolution. More specifically, 40 variables have been coded for a sample of 16 historical societies. Consistent with the model of parental choice, it is found that mating is controlled by parents, male parents exercise more control over marriage arrangements than females, and more control is exercised over female than male offspring. Finally, the specific qualities that parents desire in an in-law and offspring desire in a spouse have also been identified. The implications of these findings are discussed.

Respondents were asked whether each of 15 factors had a great deal of influence on their career choice, a little influence or no influence on it. Percentages are reported of those who specified that a factor had a great deal of influence on their career choice. UK. A total of 15,765 UK-trained doctors who graduated between 1999 and 2012. Questions about career choices and factors which may have influenced those choices, in particular comparing doctors who qualified in 2008-2012 with those who qualified in 1999-2002. Enthusiasm for and commitment to the specialty was a greater influence on career choice in the 2008-2012 qualifiers (81%) than those of 1999-2002 (64%), as was consideration of their domestic circumstances (43% compared with 20%). Prospects for promotion were less important to recent cohorts (16%) than older cohorts (21%), as were financial prospects (respectively, 10% and 14%). Domestic circumstances and working hours were considered more important, and financial prospects less important, by women than men. Inclination before medical school was rated as important by 41% of doctors who were over 30 years old, compared with 13% of doctors who were under 21, at the time of starting medical school. The increasing importance of both domestic circumstances and enthusiasm for their specialty choice in recent cohorts suggest that today's young doctors prize both work-life balance and personal fulfilment at work more highly than did their predecessors. The differences in motivations of older and younger generations of doctors, men and women, and doctors who start medical school relatively late are worthy of note. © The Royal Society of Medicine.

2012-04-01

The purposes of this study were to determine: (1) whether background factors influence the choice of Communication Sciences and Disorders (CSD) as an academic major; (2) what motivates students to major in CSD; (3) the relationship between motivation to pursue CSD as a major and the attractiveness of the major; and (4) whether motivation influences the perceived value of a career in CSD. A survey of 143 undergraduates was created and administered to assess motivational factors that influence the choice of major. The participants had diverse ethnic/racial and cultural backgrounds and were enrolled in CSD courses in the Liberal Arts College of St John's University, a US American Institution in Queens, New York. Preliminary analyses indicated that ethnic/racial background and family income had no statistically significant relationship to motivations, attractiveness of CSD as a major, or career value of CSD as a major. Students scored highest on Intrinsic motivation factor (e.g., enjoy interacting with people) and the lowest on Science motivation (e.g., interested in science). Student confidence (e.g., in reaching career goals) was an important predictor in the perception of the career value of a CSD. Results of this study provide further insight into curriculum development and recruiting strategies.

Increases in fibroblast growth factor 23 precede kidney function decline in autosomal dominant polycystic kidney disease; however, the role of fibroblast growth factor 23 in autosomal dominant polycystic kidney disease has not been well characterized. We measured intact fibroblast growth factor 23 levels in baseline serum samples from 1002 participants in the HALT-PKD Study A ( n =540; mean eGFR =91±17 ml/min per 1.73 m 2 ) and B ( n =462; mean eGFR =48±12 ml/min per 1.73 m 2 ). We used linear mixed and Cox proportional hazards models to test associations between fibroblast growth factor 23 and eGFR decline, percentage change in height-adjusted total kidney volume, and composite of time to 50% reduction in eGFR, onset of ESRD, or death. Median (interquartile range) intact fibroblast growth factor 23 was 44 (33-56) pg/ml in HALT-PKD Study A and 69 (50-93) pg/ml in Study B. In adjusted models, annualized eGFR decline was significantly faster in the upper fibroblast growth factor 23 quartile (Study A: quartile 4, -3.62; 95% confidence interval, -4.12 to -3.12 versus quartile 1, -2.51; 95% confidence interval, -2.71 to -2.30 ml/min per 1.73 m 2 ; P for trend <0.001; Study B: quartile 4, -3.74; 95% confidence interval, -4.14 to -3.34 versus quartile 1, -2.78; 95% confidence interval, -2.92 to -2.63 ml/min per 1.73 m 2 ; P for trend <0.001). In Study A, higher fibroblast growth factor 23 quartiles were associated with greater longitudinal percentage increase in height-adjusted total kidney volume in adjusted models (quartile 4, 6.76; 95% confidence interval, 5.57 to 7.96 versus quartile 1, 6.04; 95% confidence interval, 5.55 to 6.54; P for trend =0.03). In Study B, compared with the lowest quartile, the highest fibroblast growth factor 23 quartile was associated with elevated risk for the composite outcome (hazard ratio, 3.11; 95% confidence interval, 1.84 to 5.25).

Landslide is one of the destructive natural geohazards in Malaysia. In addition to rainfall as triggering factos for landslide in Malaysia, topographical and geological factors play important role in the landslide susceptibility analysis. Conventional topographic factors such as elevation, slope angle, slope aspect, plan curvature and profile curvature have been considered as landslide causative factors in many research works. However, other topographic factors such as diagonal length, surface area, surface roughness and rugosity have not been considered, especially for the research work in landslide hazard analysis in Malaysia. This paper presents landslide hazard mapping using Frequency Ratio (FR) and themore » study area is Penang Island of Malaysia. Frequency ratio approach is a variant of probabilistic method that is based on the observed relationships between the distribution of landslides and each landslide-causative factor. Landslide hazard map of Penang Island is produced by considering twenty-two (22) landslide causative factors. Among these twenty-two (22) factors, fourteen (14) factors are topographic factors. They are elevation, slope gradient, slope aspect, plan curvature, profile curvature, general curvature, tangential curvature, longitudinal curvature, cross section curvature, total curvature, diagonal length, surface area, surface roughness and rugosity. These topographic factors are extracted from the digital elevation model of Penang Island. The other eight (8) non-topographic factors considered are land cover, vegetation cover, distance from road, distance from stream, distance from fault line, geology, soil texture and rainfall precipitation. After considering all twenty-two factors for landslide hazard mapping, the analysis is repeated with fourteen dominant factors which are selected from the twenty-two factors. Landslide hazard map was segregated into four categories of risks, i.e. Highly hazardous area, Hazardous area, Moderately

The introduction of Swiss DRG in 2012 offers women in Switzerland free choice of hospital. The objective of this study was to identify decision factors affecting the choice of hospital birth in Switzerland and to rate the degree of utilization of information sources. In seven Swiss hospitals, located in the German-speaking part of Switzerland, women in childbed were interviewed in writing. When choosing a hospital, factors rated by women as important were professional competence, good medical care, good obstetric competence, good nursing care and a neat and clean atmosphere. Important sources of information are recommendations of friends, own experience gained during previous hospital stays, the specialist, family, and the hospital homepage. Information meetings for pregnant women are essential for hospitals because they encourage women's decision to use the hospital. Web presence of the hospital and a good relationship with the specialists or family doctors are important, but experience of friends, family or one's own experience with stay at the hospital play a more important role. © Georg Thieme Verlag KG Stuttgart · New York.

Introduction: The article is dedicated to the motives of medical career choice studied by Ukrainian and foreign scientists, and by the authors themselves. The authors define the main motives, grouped into the pragmatic, social, scientific and professional ones, paying particular attention to the proposed reforms of the Healthcare of Ukraine "Health 2020". The aim: The study has been aimed at detection of the medical career choice factor groups and their possible correction during the medical training, defining possible influence of the Ukrainian Healthcare reformation onto alterations of the medical career choice. Materials and methods: This article is based on bibliosemantic, dialectical, comparative, analytic, synthetic and comprehensive research methods. Review and conclusion: The authors have analyzed medical career motives according to the A. Maslow hierarchy of needs, comparing the present motives with the motives to be changed after reforming the Ukrainian healthcare. The authors conclude that according to the Maslow's hierarchy of needs, the medical career choice corresponding to the first, second and third needs level would be directly related to the pragmatic, social and scientific motives, further disappointment in career, low professional performance and professional "burnout". The career choice corresponding to the last levels of the needs hierarchy is related to the professional motives and self-actualization, but, due to the applicants' age and financial status of medical specialists in Ukraine, is not likely to occur. Positive changes in medical specialists' salary rise, social protection offered by the State and state support of the profession will provide for correction of motives onto the higher level, in this way, benefiting the patients.

Role of the plurality rule in multiple choices

People are often challenged to select one among several alternatives. This situation is present not only in decisions about complex issues, e.g. political or academic choices, but also about trivial ones, such as in daily purchases at a supermarket. We tackle this scenario by means of the tools of statistical mechanics. Following this approach, we introduce and analyse a model of opinion dynamics, using a Potts-like state variable to represent the multiple choices, including the ‘undecided state’, which represents the individuals who do not make a choice. We investigate the dynamics over Erdös-Rényi and Barabási-Albert networks, two paradigmatic classes with the small-world property, and we show the impact of the type of network on the opinion dynamics. Depending on the number of available options q and on the degree distribution of the network of contacts, different final steady states are accessible: from a wide distribution of choices to a state where a given option largely dominates. The abrupt transition between them is consistent with the sudden viral dominance of a given option over many similar ones. Moreover, the probability distributions produced by the model are validated by real data. Finally, we show that the model also contemplates the real situation of overchoice, where a large number of similar alternatives makes the choice process harder and indecision prevail.

Socioeconomic factors associated with contraceptive use and method choice in urban slums of Bangladesh.

Kamal, S M Mostafa

2015-03-01

This article explores the socioeconomic factors affecting contraceptive use and method choice among women of urban slums using the nationally representative 2006 Bangladesh Urban Health Survey. Both bivariate and multivariate statistical analyses were applied to examine the relationship between a set of sociodemographic factors and the dependent variables. Overall, the contraceptive prevalence rate was 58.1%, of which 53.2% were modern methods. Women's age, access to TV, number of unions, nongovernmental organization membership, working status of women, number of living children, child mortality, and wealth index were important determinants of contraceptive use and method preference. Sex composition of surviving children and women's education were the most important determinants of contraceptive use and method choice. Programs should be strengthened to provide nonclinical modern methods free of cost among the slum dwellers. Doorstep delivery services of modern contraceptive methods may raise the contraceptive prevalence rate among the slum dwellers in Bangladesh. © 2011 APJPH.

Poor interpersonal relationships with women especially those living positively with HIV/AIDS can make them take risks that would expose their new born and others to infection during childbirth. The factors that influence childbirth choices of people living positively with HIV/AIDS (PLWHA) deserve attention. Sometimes, women, especially PLWHA, for several reasons, resort to the use of other health care services instead of the general hospitals equipped for ante-natal care (ANC). This study aims to identify factors and conditions that determine childbirth choices of PLWHA in the Abia State of Nigeria. A cross-sectional descriptive study was carried out using a total sample of 96 PLWHA who attend meetings with the network of PLWHA and also a purposive convenience sample of 45 health workers. Data collection instruments were questionnaire, focus group discussions and interview guides. Data was analyzed both qualitatively and quantitatively using simple percentages. There was a low patronage for hospital services. A total of 79 (82%) PLWHA did not use hospital services due to the lack of confidentiality. In total, 61 (64%) PLWHA had their childbirth with Traditional Birth Attendants (TBAs) at home. Embarrassment, rejection, interpersonal conflicts with health workers, non-confidentiality, cultural stigma and stigmatization were among the factors that encouraged childbirth choices. On the whole, 82 (85%) of the PLWHA discontinued ANC services because of stigmatization. Poor interpersonal relationships between health workers and PLWHA facilitated PLWHA childbirth choices more than other factors. PLWHA and health workers termed management of belligerent tendencies against each other as their greatest concern. Therefore, concerted effort is needed to improve health workers/PLWHA relationship in hospitals. This would minimize factors and/or conditions that encourage HIV infection. Exposing PLWHA to factors that influence childbirth at home demonstrates high risks of mother

Work analysis is fundamental to designing effective human resource systems. The current investigation extends previous research by identifying the differential effects of common design decisions, purposes, and organizational contexts on the data generated by work analyses. The effects of 19 distinct factors that span choices of descriptor, collection method, rating scale, and data source, as well as project purpose and organizational features, are explored. Meta-analytic results cumulated from 205 articles indicate that many of these variables hold significant consequences for work analysis data. Factors pertaining to descriptor choice, collection method, rating scale, and the purpose for conducting the work analysis each showed strong associations with work analysis data. The source of the work analysis information and organizational context in which it was conducted displayed fewer relationships. Findings can be used to inform choices work analysts make about methodology and postcollection evaluations of work analysis information. (c) 2015 APA, all rights reserved).

Multiple regression analysis of factors influencing dominant hand grip strength in an adult Malaysian population.

2012-01-01

Grip strength is an important measure used to monitor the progression of a condition, and to evaluate outcomes of treatment. We assessed how various physical and social factors predict normal grip strength in an adult Malaysian population of mixed Asian ethnicity (254 men, 246 women). Grip strength was recorded using the Jamar dynamometer. The mean grip strength for the dominant hand was 29.8 kg for men and 17.6 kg for women. Multiple regression analysis demonstrated that the dominant hand grip strength was positively associated with height and body mass index, and negatively associated with age for both sexes. Dominant hand grip strength was related to work status for men (p < 0.05) but not for women. However, there was no difference in grip strength among ethnic groups.

The aim of this analysis was to identify factors associated with the choice of type 2 diabetes mellitus (T2DM) therapy at the time of intensification of antidiabetic treatment across 4 European countries. Antidiabetic drug prescription/dispensing records and patients' characteristics were obtained from the electronic health care records of patients with T2DM from the Netherlands (NL), Italy, and Spain (ES) (all, 2007-2011); and the United Kingdom (UK; 2008-2012). Oral monotherapy was defined as first-line; oral dual therapy, as second-line; >2 oral treatments or oral combined with an injectable, as third-line; and injectables only, as fourth-line treatment. Treatment intensification was defined as the start of a higher line of treatment. Comedication, comorbidities, clinical parameters, and other factors associated with treatment choice were identified using multivariate relative risk estimation by Poisson regression with robust error variance. In the 5-year study period, 485,120 patients (79% of the treated T2DM population) underwent treatment intensification. Changes in treatment choice were clearly visible over the study period, such as a decline in the use of thiazolidinediones (NL, ES, UK) and increases in the use of dipeptidyl peptidase-4 inhibitors (DPP4i) (NL, ES, UK) and glucagon-like peptide-1 receptor agonists (UK). With first-line treatment, advanced age and renal comorbidity were associated with the use of sulfonylureas (SUs; all countries), whereas high body mass index (BMI) was inversely associated with SU use in the United Kingdom and Spain. With second-line treatment, advanced age was associated with metformin + SU use (all countries); and renal comorbidity with SU + DPP4i use in the United Kingdom and the Netherlands. High BMI was associated with metformin + thiazolidinedione (TZD) use in the United Kingdom and Spain, and with metformin + DPP4i in the United Kingdom. With third-line treatment, advanced age and renal comorbidity were associated

Interdependent Utilities: How Social Ranking Affects Choice Behavior

PubMed Central

Bault, Nadège; Coricelli, Giorgio; Rustichini, Aldo

2008-01-01

Organization in hierarchical dominance structures is prevalent in animal societies, so a strong preference for higher positions in social ranking is likely to be an important motivation of human social and economic behavior. This preference is also likely to influence the way in which we evaluate our outcome and the outcome of others, and finally the way we choose. In our experiment participants choose among lotteries with different levels of risk, and can observe the choice that others have made. Results show that the relative weight of gains and losses is the opposite in the private and social domain. For private outcomes, experience and anticipation of losses loom larger than gains, whereas in the social domain, gains loom larger than losses, as indexed by subjective emotional evaluations and physiological responses. We propose a theoretical model (interdependent utilities), predicting the implication of this effect for choice behavior. The relatively larger weight assigned to social gains strongly affects choices, inducing complementary behavior: faced with a weaker competitor, participants adopt a more risky and dominant behavior.

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.

It is important to inform medical educators and workforce planners in Anaesthesia about early career choices for the specialty, factors that influence them and to elucidate how recent choices of men and women doctors relate to the overall historical trends in the specialty's popularity. We analysed longitudinal data on career choice, based on self-completed questionnaires, from national year-of-qualification cohorts of UK-trained doctors from 1974 to 2012 surveyed one, three and 5 years post-qualification. Career destination data 10 years post-qualification were used for qualifiers between 1993 and 2002, to investigate the association between early choice and later destinations. In years 1, 3 and 5 post-qualification, respectively, 59.9% (37,385), 64.6% (31,473), and 67.2% (24,971) of contactable doctors responded. There was an overall increase, from the early to the later cohorts, in the percentage of medical graduates who wished to enter anaesthesia: for instance year 1 choices rose from 4.6 to 9.4%, comparing the 1974 and 2012 cohorts. Men were more likely than women to express an early preference for a career in anaesthesia: for example, at year 3 after qualification anaesthesia was the choice of 10.1% of men and 7.9% of women. There was a striking increase in the certainty with which women chose anaesthesia as their future career specialty in recent compared to earlier cohorts, not reflected in any trends observed in men choosing anaesthesia. Sixty percent of doctors who were anaesthetists, 10 years after qualifying, had specified anaesthesia as their preferred specialty when surveyed in year 1, 80% in year 3, and 92% in year 5. Doctors working as anaesthetists were less likely than those working in other hospital specialties to have specified, as strong influences on specialty choice, 'experience of the subject' as students, 'inclinations before medical school', and 'what I really want to do'. Men anaesthetists were more influenced in their specialty

2017-09-01

In the setting of increasing student debt, a rapidly changing health care system, and growing transparency in the age of outcome reporting, residents have many factors to consider when determining which fellowship to pursue. An institutional review board-approved link to an online survey was emailed to orthopedic surgery trainees across the United States. Demographics were collected, and 14 fellowship influences were assessed using a Likert scale. A total of 360 responses were received. Of the respondents, 85.5% (n=308) were male and 14.5% (n=52) were female. Responses were received from every region of the United States and from every postgraduate year. Respondents represented the gamut of relationship status and indebtedness. Respondents were interested in all of the current major subspecialties. Pursuit of an intellectually stimulating subspecialty had the highest average Likert score (3.38), followed by variety of cases (3.26). The lowest scores were for residency program with a strong tradition of placing into a particular subspecialty (2.08) and potential to conduct research in that subspecialty (2.09). Marital status, number of children, and level of debt did not significantly affect the importance of factors in selecting a fellowship. Choice of subspecialty did influence the level of importance of various factors. Intellectual stimulation and a strong mentor were the most influential factors in the decision to pursue a given fellowship. Because fellowship is now the norm, it is important to understand the motives behind young orthopedic surgeons' career aspirations. [Orthopedics. 2017; 40(5):e820-e824.].

The objective of this study was to describe the demographics of the Class of 2006, Western College of Veterinary Medicine, and to determine which factors influenced the graduates’ career path choices. Data were collected via an on-line survey and the response rate was 95.7% (67/70). The majority (57%) of graduates were starting their veterinary career in a food animal-related (FAR) job. Two factors were significantly associated with this choice: 1) those raised in, or near, a small center (population < 10 000) were 3.4 times (P = 0.03) more likely to accept a FAR position than were those raised in a large center (> 10 000), and 2) graduates with a bachelor of science in agriculture (BSc Ag) were 4.5 times (P = 0.04) more likely to begin their career as a FAR practitioner than were those without such a degree. However, 9 of the 16 graduates having a BSc Ag had an urban upbringing. PMID:18309746

Rational choice of peritoneal dialysis catheter.

The peritoneal catheter should be a permanent and safe access to the peritoneal cavity. Catheter-related problems are often the cause of permanent transfer to hemodialysis (HD) in up to 20% of peritoneal dialysis (PD) patients; in some cases, these problems require a temporary period on HD. Advances in connectology have reduced the incidence of peritonitis, and so catheter-related complications during PD have become a major concern. In the last few years, novel techniques have emerged in the field of PD: new dialysis solutions, better connectology, and cyclers for automated PD. However, extracorporeal dialysis has continued to improve in terms of methods and patient survival, but PD has failed to do so. The main reason is that peritoneal access has remained problematical. The peritoneal catheter is the major obstacle to wide-spread use of PD. Overcoming catheter-related problems means giving a real chance to development of the peritoneal technique. Catheters should be as efficient, safe, and acceptable as possible. Since its introduction in the mid-1960s, the Tenckhoff catheter has not become obsolete: dozens of new models have been proposed, but none has significantly reduced the pre-dominance of the first catheter. No convincing prospective data demonstrate the superiority of any peritoneal catheter, and so it seems that factors other than choice of catheter are what affect survival and complication rates. Efforts to improve peritoneal catheter survival and complication rates should probably focus on factors other than the choice of catheter. The present article provides an overview of the characteristics of the best-known peritoneal catheters.

Factors affecting food choices of older adults from high and low socioeconomic groups: a discrete choice experiment.

Healthiness, price, and convenience are typically indicated as important motives for food choices; however, it is largely unknown to what extent older adults from high and low socioeconomic groups differ in these underlying motives. A discrete choice experiment (DCE) is an innovative way to elicit implicit motives for food choices. The aim was to investigate differences in food motives between socioeconomic groups by means of a DCE. A DCE was carried out during a face-to-face interview among older adults as part of the Health and Living Conditions in Eindhoven and surrounding cities (GLOBE) cohort study, The Netherlands. Participants (n = 399; mean age: 63.3 y) were offered a series of choice sets about a usual dinner at home and were asked to choose in each choice set between 2 meals and an opt-out choice, with different combinations of attribute levels. We included 5 meal attributes (taste, healthiness, preparation time, travel time to shops, and price) and 3 or 4 levels for each attribute. Data were analyzed by multinomial logit models. Healthiness, taste, price, and travel time to the grocery store proved to significantly influence older adults' meal decisions; preparation time was not significant. Healthiness was the most important attribute for all of the participants. More highly educated participants rated a healthy and less expensive meal to be more important than did less educated participants. Those with a high income rated a meal that was healthy and very tasteful to be more important than did those with a lower income. Healthiness, taste, price, and travel time to grocery shops influenced older adults' meal decisions. Higher socioeconomic groups valued health more than did lower socioeconomic groups. DCEs represent a promising method to gain insight into the relative importance of motives for food choices.

The movement of skilled physicians from the public to the private sector is a key constraint to achieving universal health coverage and is currently affecting health systems worldwide. This systematic review aims to assess factors influencing physicians' choice of workplace, and policy interventions for retaining physicians in the public sector. Five literature databases were searched. Studies were included in the review if they focused on at least one of the following criteria: (i) incentives or motivators for retaining physicians in the public sector, (ii) pull factors that encouraged physicians to move to the private sector, (iii) push factors that forced physicians to leave the public sector, (iv) policy interventions or case studies that addressed physician retention in the public sector, and (v) qualitative reviews of policy interventions that were implemented in different health system settings. Nineteen articles met the inclusion criteria. Six major themes that affected physicians' choice of workplace were identified including: financial incentives, career development, infrastructure and staffing, professional work environment, workload and autonomy. The majority of the studies suggested that the use of financial incentives was a motivator in retaining physicians in the public sector. The review also identified policy interventions including: regulatory controls, incentives and management reforms. Regulatory controls and incentives were the two most frequently reported policy interventions. While factors affecting physicians' choice of workplace are country specific, financial incentives and professional development are core factors. Other factors are highly influenced by context, and thus, it would be useful for future cross-country research to use standardized data collection tools, allowing comparison of contextual factors as well as the examination of how context affects physician retention in the public sector.

Rwanda currently faces a severe shortage of trained medical personnel, including physician anesthesiologists. The recruitment of residents into the anesthesia program has been consistently low. This study aimed at determining the factors that influence undergraduates' decision to pursue anesthesia as a career choice. A questionnaire was created and administered to final year undergraduate medical students at the University of Rwanda. The questionnaire was created based on factors identified from literature review and key informant interviews. The questionnaire was translated, field-tested, and refined. The final survey questionnaire contains 27 4-point Likert scale items and 4 free-text questions. Seventy-nine final year undergraduate medical students responded to the survey. Only 2 students (2.5%) chose anesthesia as their top choice for postgraduate training. The most frequently named factors for not choosing anesthesiology were long work hours and high stress level, insufficient mentorship, and low job opportunity. The issues identified by our survey must be considered when making efforts toward increasing anesthesia recruitment in Rwanda. Factors such as lack of material resources and high workload will not be easily addressed. Others can be addressed through changes in medical student anesthesiology rotations and better mentorship by anesthesiologists during formative years. Focusing on factors that can be changed now may increase enrollment into anesthesiology. Future studies will include broadening the survey population and further investigating the influencing factors elucidated by this study.

The journal impact factor is a measure of the citability of articles published in that journal—the more citations generated, the more important that article is considered to be, and as a consequence the prestige of the journal is enhanced. The impact factor is not without controversy, and it can be manipulated. It no longer dominates the choices of journals to search for information. Online search engines, such as PubMed, can locate articles of interest in seconds across journals regardless of high or low impact factors. Editors desiring to increase their influence will need to focus on a fast and friendly submission and review process, early online and speedy print publication, and encourage the rapid turnaround of high-quality peer reviews. Authors desiring to have their results known to the world have never had it so good—the internet permits anyone with computer access to find the author's work. PMID:20806031

This study assessed the factors affecting the choice of type of delivery with breast feeding in Iranian mothers. This Cross section descriptive analytic study was performed using a random sampling technique, using data from 400 pregnant women who attended the maternity centers in Borazjan and Kazerun in Iran in 2014. A questionnaire covering demographic characteristics, mode of delivery and postpartum conditions was completed for each mother. Descriptive analysis and Chi square test were used along with SPSS 23 software to statistically analyze the data and p-value less than 0.05 was considered for statistical significance. In this study, the rate of normal delivery and cesarean operation are considered equal. In the main factors influencing the choice of delivery, mothers' education level (p=0.028) and pregnancy status (p=0.041) showed a significant relationship. Although no significant association between child nutrition with the type of delivery was found, duration of breastfeeding with the type of delivery showed significant association (p=0.046). Although cesarean delivery in many cases is life-saving for mother and fetus; in addition to medical indications, parents with higher education and pregnancy status are also important factors in increasing the rate of cesarean section compared to vaginal delivery. Babies of mothers with normal delivery had a longer time of breastfeeding. Further studies in Iran are necessary, regarding the reasons for high cesarean section and their outcomes.

Among other factors, companion animal (small animal and equine) (CA) practitioners were less likely to have been raised in, or near to, a small center (≤ 10 000), were more concerned with their workload (hours of work and number of nights on-call), and preferred to work in progressive practices. Food animal (FA) practitioners were more likely to be male, have been raised in a small center, have been raised in the Province of Saskatchewan, and to have self-assessed themselves as having an above average knowledge of agriculture at the time they applied for admission to veterinary college. Mixed animal (MA) practitioners had more factors in common with FA than with CA practitioners. Three main factors were associated with leaving mixed or food animal practice: hours of work and too many nights on-call, the level of remuneration, and lack of support and mentorship. PMID:19721783

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.

Objectives The movement of skilled physicians from the public to the private sector is a key constraint to achieving universal health coverage and is currently affecting health systems worldwide. This systematic review aims to assess factors influencing physicians’ choice of workplace, and policy interventions for retaining physicians in the public sector. Methods Five literature databases were searched. Studies were included in the review if they focused on at least one of the following criteria: (i) incentives or motivators for retaining physicians in the public sector, (ii) pull factors that encouraged physicians to move to the private sector, (iii) push factors that forced physicians to leave the public sector, (iv) policy interventions or case studies that addressed physician retention in the public sector, and (v) qualitative reviews of policy interventions that were implemented in different health system settings. Results Nineteen articles met the inclusion criteria. Six major themes that affected physicians’ choice of workplace were identified including: financial incentives, career development, infrastructure and staffing, professional work environment, workload and autonomy. The majority of the studies suggested that the use of financial incentives was a motivator in retaining physicians in the public sector. The review also identified policy interventions including: regulatory controls, incentives and management reforms. Regulatory controls and incentives were the two most frequently reported policy interventions. Conclusion While factors affecting physicians’ choice of workplace are country specific, financial incentives and professional development are core factors. Other factors are highly influenced by context, and thus, it would be useful for future cross–country research to use standardized data collection tools, allowing comparison of contextual factors as well as the examination of how context affects physician retention in the public

Aim To use baseline characteristics of the Cardiovascular Risk Evaluation in people with type 2 Diabetes on Insulin Therapy study population to identify factors that could explain the choice of insulin therapy when beginning insulin. Methods The source, non-interventional, longitudinal, long-term study involves 314 centres in 12 countries in five regions. People were enrolled having started any insulin regimen in the previous 12 months. To identify factors associated with the choice of insulin regimen, multivariable backward logistic regression was performed on eligible physician and participant explanatory variables. Results Participants (N = 3031) had mean age 62 years, diabetes duration 11 years, body mass index 29.3 kg/m2 and an HbA1c of 9.5%. Participants in Japan had less hypertension, smoked more and used fewer concomitant medications than those of other regions. Only physician location (rural or urban) influenced the choice of insulin in Japan. In the other four-regions-combined, physician location, specialty, sex and practice type influenced choice of insulin as did participant location, baseline HbA1c, use of glucose-lowering therapies and prior insulin secretagogue use. Conclusion Choice of initial insulin regimen was influenced by several physician and participant characteristics in Canada and Europe, but only by physician location in Japan. PMID:22519930

The characteristics of vadose zone vulnerability dominating factors (VDFs) are closely related to the migration and transformation mechanisms of contaminants in the vadose zone, which directly affect the state of the contaminants percolating to the groundwater. This study analyzes the hydrogeological profile of the pore water regions in the vadose zone, and conceptualizes the vadose zone as single lithologic, double lithologic, or multi lithologic. To accurately determine how the location of the pollution source influences the groundwater, we classify the permeabilities (thicknesses) of different media into clay-layer and non-clay-layer permeabilities (thicknesses), and introduce the maximum pollution thickness. Meanwhile, the physicochemical reactions of the contaminants in the vadose zone are represented by the soil adsorption and soil degradability. The VDFs are determined from the factors and parameters in groundwater vulnerability assessment. The VDFs are identified and sequenced in simulations and a sensitivity analysis. When applied to three polluted sites in China, the method improved the weighting of factors in groundwater vulnerability assessment, and increased the reliability of predicting groundwater vulnerability to contaminants.

Choosing a medical specialty is an important, complex, and not fully understood process. The present study investigated the factors that are related to choosing and rejecting medical specialties in a group of students and recent medical doctors. A cross-sectional survey of 1,223 medical students and doctors was performed in Brazil in 2012. A standardized literature-based questionnaire was applied that gathered preferable or rejected specialties, and asked questions about extracurricular experiences and the influence of 14 factors on a Likert-type scale from 0 to 4. Specialties were grouped according to lifestyle categories: controllable and uncontrollable, which were subdivided into primary care, internal medicine, and surgical specialties. Notably, the time period of rejection was usually earlier than the time period of intended choice (p < 0.0001, χ(2) = 107.2). The choice mainly occurred during the internship period in medical school (n = 466; 38.7%). An overall large frequency of participation in extracurricular activities was observed (n = 1,184; 95.8%), which were highly associated with the respective medical area. Orthopedic surgery had the highest correlation with participation in specialty-specific organized groups (OR = 59.9, 95% CI = 21.6-166.3) and psychiatry was correlated with participation in research groups (OR = 18.0, 95% CI = 9.0-36.2). With regard to influential factors in controllable lifestyle specialties, "financial reason" (mean score ± standard deviation: 2.8 ± 1.0; median = 3) and "personal time" (3.1 ± 1.3; median = 4) were important factors. In primary care, these factors were less important (1.7 ± 1.3 and 1.7 ± 1.5, respectively; median = 2 for both), and higher scores were observed for "curricular internship" (3.2 ± 1.1, median = 4) and "social commitment" (2.6 ± 1.3, median = 3).

PubMed Central

2010-01-01

Objectives To determine factors that influenced students' choice of pharmacy as a major and assess relationships between these factors and anticipatory socialization. Methods Two hundred fifteen freshman and sophomore students enrolled in a 0-6 doctor of pharmacy program completed a survey instrument on which they rated 6 motivational factors in their decision to major in pharmacy and answered questions related to anticipatory socialization. Bivariate and multivariate analyses were used to answer the research questions posed. Results Female students ranked desire to help others as a stronger motivating factor in their decision to pursue a career in pharmacy than did male students. Caucasian students rated providing more career opportunities and providing an entry-level doctorate as stronger motivating factors for pursuing pharmacy than did Asian students. Asian students had lower levels of anticipatory socialization than other students. Students with higher levels of motivation had higher levels of anticipatory socialization. Conclusion Results of this study provide further insight into effective recruiting strategies and recommendations for improved pharmacy education. PMID:20585437

The two studies describe the development of three complementary scales to the Food Choice Questionnaire developed by Steptoe, Pollard & Wardle (1995). The new items address various ethical food choice motives and were derived from previous studies on vegetarianism and ethical food choice. The items were factor analysed in Study 1 (N=281) and the factor solution was confirmed in Study 2 (N=125), in which simple validity criteria were also included. Furthermore, test-retest reliability was assessed with a separate sample of subjects (N=36). The results indicated that the three new scales, Ecological Welfare (including subscales for Animal Welfare and Environment Protection), Political Values and Religion, are reliable and valid instruments for a brief screening of ethical food choice reasons.

2018-01-03

We have performed a narrative synthesis. A literature search was conducted between January 2000 and June 2014 in 7 databases. The initial search identified 2717 articles; 319 underwent abstract screening, 67 underwent full-text screening, and 25 final articles were included. This review looked at early stage breast cancer in women only, excluding ductal carcinoma in situ and advanced breast cancer. A conceptual framework was created to organize the central constructs underlying women's choices: clinicopathologic factors, physician factors, and individual factors with subgroups of sociodemographic, geographic, and personal beliefs and preferences. This framework guided our review's synthesis and analysis. We found that larger tumor size and increasing stage was associated with increased rates of mastectomy. The results for age varied, but suggested that old and young extremes of diagnostic age were associated with an increased likelihood of mastectomy. Higher socioeconomic status was associated with higher breast conservation therapy (BCT) rates. Resident rural location and increasing distance from radiation treatment facilities were associated with lower rates of BCT. Individual belief factors influencing women's choice of mastectomy (mastectomy being reassuring, avoiding radiation, an expedient treatment) differed from factors influencing choice of BCT (body image and femininity, physician recommendation, survival equivalence, less surgery). Surgeon factors, including female gender, higher case numbers, and individual surgeon practice, were associated with increased BCT rates. The decision-making process for women with early stage breast cancer is complicated and affected by multiple factors. Organizing these factors into central constructs of clinicopathologic, individual, and physician factors may aid health-care professionals to better understand this process.

Schneeweis, Nicole; Zweimüller, Martina

2012-01-01

Gender segregation in employment may be explained by women's reluctance to choose technical occupations. However, the foundations for career choices are laid much earlier. Educational experts claim that female students are doing better in math and science and are more likely to choose these subjects if they are in single-sex classes. One possible explanation is that coeducational settings reinforce gender stereotypes. In this paper, we identify the causal impact of the gender composition in coeducational classes on the choice of school type for female students. Using natural variation in the gender composition of adjacent cohorts within schools, we show that girls are less likely to choose a traditionally female dominated school type and more likely to choose a male dominated school type at the age of 14 if they were exposed to a higher share of girls in previous grades.

Choosing a medical specialty is a poorly understood process. Although studies conducted around the world have attempted to identify the factors that affect medical students' choice of specialty, data is scarce on the factors that influence the choice of specialty of Saudi Arabian medical students, in particular those planning a career in emergency medicine (EM). In this study, we investigated whether Saudi medical students choosing EM are influenced by different factors to those choosing other specialties. A cross-sectional survey was conducted at King Saud bin Abdulaziz University for Health Sciences (KSAUHS), Riyadh, Saudi Arabia. The questionnaire distributed among all undergraduate and postgraduate medical students of both sexes in the second and third phases (57% were males and 43% were females). A total of 436 students answered the questionnaire, a response rate of 53.4%. EM group was most influenced by hospital orientation and lifestyle and least influenced by social orientation and prestige provided by their specialty. Unlike controllable lifestyle (CL) group and primary care (PC) group, EM reported lesser influence of social orientation on their career choice. When compared with students primarily interested in the surgical subspecialties (SS), EM group were less likely to report prestige as an important influence. Moreover, students interested in SS reported a leaser influence of medical lifestyle in comparison to EM group. When compared with CL group, EM group reported more interest in medical lifestyle. We found that students primarily interested in EM had different values and career expectations to other specialty groups. The trends in specialty choice should be appraised to meet future needs.

The environment is increasingly turning to a vital and very important issue for all people. By increasing environmental concerns as well as legislating and regulating rules on the protection of the environment and the emergence of green consumers, implementing green marketing approach for organizations seems to be more crucial and essential. As a result, the need for ecological products and green business activities compels companies to combine environmental issues with marketing strategies. The first step in the success of companies and organizations is to identify consumers and their consumption behaviors correctly and accurately. So, the purpose of this study is to identify effective factors for the choice of consumers of green products. We used consumption values (functional value, social value, emotional value, conditional value, epistemic value, and environmental value) as the effective factor for choosing green products. The original place of this research was in Tehran, capital city of Iran, which is one of the most polluted cities in the world due to environmental issues. The results from the survey questionnaires are analyzed using confirmatory factor analysis and structural equation modelling. The results indicated that functional value-price, functional value-quality, social value, epistemic value, and environmental value had significantly positive effects on the choice of green products; also, conditional value and emotional value had no influence on it. It was concluded that the main influential factors for consumers' choice behavior regarding green products included environmental value and epistemic value. This study emphasized the proper pricing of green products by producers and sellers.

2016-03-01

The effects of free-carrier-induced shift and broadening on the carrier distribution function are studied considering different extreme cases for carrier statistics (Fermi-Dirac and random carrier distributions) as well as quantum dot (QD) ensemble inhomogeneity and state separation using a Monte Carlo model. Using this model, we show that the dominant factor determining the carrier distribution function is the free carrier effects and not the choice of carrier statistics. By using empirical values of the free-carrier-induced shift and broadening, good agreement is obtained with experimental data of QD materials obtained under electrical injection for both extreme cases of carrier statistics.

A questionnaire was developed and validated which assesses factors influencing career choices of medical students and their perception of possibilities in general practice. The first questionnaire version, which was developed based on a systematic literature review, was checked for comprehensibility and redundancy using concurrent think aloud. The revised version was filled out by a pilot sample of medical students and the factor structure was assessed using principal component analysis (PCA). The final version was filled out in an online survey by medical students of all 5 Medical Faculties in the federal state of Baden-Wuerttemberg. The factor structure was validated with a confirmatory factor analysis (CFA). Reliability was assessed as internal consistency using Cronbach's α. The questionnaire comprises 2 parts: ratings of (A) the individual importance and of (B) the possibilities in general practice on 5-point scales. The first version comprising 118 items was shortened to 63 items after conducting interviews using concurrent think aloud. A further 3 items giving no information were removed after piloting the questionnaire on 179 students. The 27 items of part A were structured in 7 factors (PCA): image, personal ambition, patient orientation, work-life balance, future perspectives, job-related ambition, and variety in job. This structure had a critical fit in the CFA applied to the final version filled out by 1 299 students. Internal consistency of the factors was satisfactory to very good (Cronbach's α=0.55-0.81). The questionnaire showed good psychometric properties. Further, not assessed factors influence career choice resulting in unexplained variance in our dataset and the critical fit of the model. © Georg Thieme Verlag KG Stuttgart · New York.

Factors Influencing Host Plant Choice and Larval Performance in Bactericera cockerelli

2014-01-01

Among the many topics of interest to ecologists studying associations between phytophagous insects and their host plants are the influence of natal host plant on future oviposition decisions and the mechanisms of generalist versus specialist host selection behavior. In this study, we examined the oviposition preferences, behavior and larval development of the tomato/potato psyllid, Bactericera cockerelli. By rearing psyllids with two distinct geographically-linked haplotypes on different host plants, we were able to examine the role of natal host plant and potential local adaptation on host plant usage. Choice bioassays among three host species demonstrated that psyllids from California had clear preferences that were influenced by natal plant. We further found that patterns in choice bioassays corresponded to observed feeding and movement responses. No-choice bioassays demonstrated that there is little to no association between development and host-plant choice for oviposition, while also indicating that host choice varies between haplotypes. These findings support the concept that mothers do not always choose oviposition sites optimally and also add support for the controversial Hopkins' host selection principle. PMID:24710468

Data from an in situ monitoring network and five ozone sondes are analysed during August of 2012, and a high tropospheric ozone episode is observed around the 8th of AUG. The Community Multi-scale Air Quality (CMAQ) model and its process analysis tool were used to study factors and mechanisms for high ozone mixing ratio at different levels of ozone vertical profiles. A sensitive scenario without chemical initial and boundary conditions (ICBCs) from MOZART4-GEOS5 was applied to study the impact of stratosphere-troposphere exchange (STE) on vertical ozone. The simulation results indicated that the first high ozone peak near the tropopause was dominated by STE. Results from process analysis showed that: in the urban area, the second peak at approximately 2 km above ground height was mainly caused by local photochemical production. The third peak (near surface) was mainly caused by the upwind transportation from the suburban/rural areas; in the suburban/rural areas, local photochemical production of ozone dominated the high ozone mixing ratio from the surface to approximately 3 km height. Furthermore, the capability of indicators to distinguish O 3 -precursor sensitivity along the vertical O 3 profiles was investigated. Two sensitive scenarios, which had cut 30% anthropogenic NO X or VOC emissions, showed that O 3 -precursor indicators, specifically the ratios of O 3 /NOy, H 2 O 2 /HNO 3 or H 2 O 2 /NO Z , could partly distinguish the O 3 -precursor sensitivity between VOCs-sensitive and NOx-sensitive along the vertical profiles. In urban area, the O 3 -precursor relationship transferred from VOCs-sensitive within the boundary layer to NOx-sensitive at approximately 1-3 km above ground height, further confirming the dominant roles of transportation and photochemical production in high O 3 peaks at the near-ground layer and 2 km above ground height, respectively.

Few data exist on internal medicine trainees' selection of cardiology training, although this is important for meeting future cardiology workforce needs. To discover trainees' professional development preferences and perceptions of cardiology, and their relationship to trainees' career choice. We surveyed trainees to discover their professional development preferences and perceptions of cardiology and the influence of those perceptions and preferences on the trainees' career choices. Participants rated 38 professional development needs and 19 perceptions of cardiology. Data collection took place from February 2009, through January 2010. Data analysis was conducted from May 2017 to December 2017. Multivariable models were used to determine the association of demographics and survey responses with prospective career choice. A total of 4850 trainees were contacted, and 1123 trainees (of whom 625 [55.7%] were men) in 198 residency programs completed surveys (23.1% response; mean [SD] age, 29.4 [3.5] years). Principal component analysis of survey responses resulted in 8-factor and 6-factor models. Professional development preferences in descending order of significance were stable hours, family friendliness, female friendliness, the availability of positive role models, financial benefits, professional challenges, patient focus, and the opportunity to have a stimulating career. The top perceptions of cardiology in descending order of significance were adverse job conditions, interference with family life, and a lack of diversity. Women and future noncardiologists valued work-life balance more highly and had more negative perceptions of cardiology than men or future cardiologists, who emphasized the professional advantages available in cardiology. Professional development factors and cardiology perceptions were strongly associated with a decision to pursue or avoid a career in cardiology in both men and women.

Impact of the Choice of Normalization Method on Molecular Cancer Class Discovery Using Nonnegative Matrix Factorization.

PubMed

Yang, Haixuan; Seoighe, Cathal

2016-01-01

Nonnegative Matrix Factorization (NMF) has proved to be an effective method for unsupervised clustering analysis of gene expression data. By the nonnegativity constraint, NMF provides a decomposition of the data matrix into two matrices that have been used for clustering analysis. However, the decomposition is not unique. This allows different clustering results to be obtained, resulting in different interpretations of the decomposition. To alleviate this problem, some existing methods directly enforce uniqueness to some extent by adding regularization terms in the NMF objective function. Alternatively, various normalization methods have been applied to the factor matrices; however, the effects of the choice of normalization have not been carefully investigated. Here we investigate the performance of NMF for the task of cancer class discovery, under a wide range of normalization choices. After extensive evaluations, we observe that the maximum norm showed the best performance, although the maximum norm has not previously been used for NMF.

To assess the factors that influence medical students' borrowing and how these factors may affect access to the profession, specialty choice, and medical graduates' repayment behaviors. The borrowing patterns of the 3,495 indebted students enrolled at Jefferson Medical College of Thomas Jefferson University between 1989-90 and 1994-95 were analyzed. (Debt included both subsidized and unsubsidized debt.) These borrowing patterns were assessed in relation to changes in the cost of education, family (i.e., parents') income, availability of grant funding, legislative changes to loan-eligibility criteria (specifically, the Higher Education Amendments of 1992), and average interest rates on federal unsubsidized loans. The annual changes in average debt levels suggest that while cost of education, family resources, and availability of grant funding may be significant factors, changes in loan eligibility and prevailing interest rates on unsubsidized loan source also influence medical students' borrowing. A comparison of the borrowing patterns for three income groups (low, middle, high) further demonstrated that while overall fluctuations for low-income group mirrored changes in the cost and resource variables, annual borrowing fluctuations for the middle- and high-income groups were more reflective of the expansion of loan eligibility and reduced interest rates on unsubsidized loans. From 1989-90 to 1994-95 the average cost of education increased by $2,368. Average unsubsidized debt increased by $1,544 for the low-income group, $3,960 for the middle-income group, and $4,439 for the high-income group. The percentage of unsubsidized funding included in the borrowers' financing packages increased by just under 6% for the low-income group but almost 10% and 11% for the middle- and high-income groups, respectively. The results suggest that medical students borrow for a variety of reasons, ranging from financial need to personal financing or lifestyle choices. These reasons

Introduction Given the competitive nature of the health market and the multiplicity of factors that may contribute towards patient’s choices of a hospital, patients’ needs and preferences for a hospital must be considered in the planning and decision making of hospitals and health care organizations. This study aimed to identify the factors that contribute to patient’s choices of a clinic and the importance of each factor. Methods A mixed-method approach was used to collect quantitative and qualitative data in two phases. The study was conducted in a hospital clinic in 2014. Qualitative data were collected by face-to-face semi-structured interviews of a sample of 22 managers and heads of outpatient wards. The self-administered questionnaire designed for this study collected quantitative data from a stratified random sample of 381 patients referred to this clinic. The qualitative data were analyzed by a system of coding, while parametrical statistical analyses were conducted to analyze the quantitative data using the independent-samples t-test and ANOVA in SPSS software, version 21.0. Results The qualitative data indicated that there were 21 factors that may contribute to patient’s choices of a clinic, and these factors were classified into six categories, i.e., facilities and physical assets, physicians and employees, location and place, services, price, and promotion. Among the 16 questions studied in the quantitative questionnaire, the highest and lowest means were related to “appropriate clinic environment” (2.47 ± 0.58) and “advertising through TV and radio, the Internet, newspapers, etc.” (1.77 ± 0.75), respectively. There were significant associations between “having experienced and responsive personnel, including physicians and employees” and the patient’s gender and frequency of referrals, between “belonging to the Armed Forces” and the patient’s age and frequency of referrals, between “advertising through TV and radio, the

A consideration of the future specialization interests of undergraduate medical students might help in understanding the needs of higher medical education and future manpower availability for healthcare in a country. This study assessed the career of choice made by medical students of the Addis Ababa University in the year 2012. A cross-sectional study was conducted among 161 medical students of the Addis Ababa University, School of Medicine, Ethiopia in April 2012 using a self-administered questionnaire. Data were analyzed using computer based statistical software IBM SPSS data editor version 20.0. In addition to descriptive statistics difference in proportions was compared using Chi-square test Of the 161 students, 101 (62.7%) were male. The mean age of respondents was 24.1 years (SD 2.02, ranging from 21 to 35). Majority, 138 (85.7) wanted to pursue their specialty training in the near future, their first career of choice being surgery for, 50 (31.1%), followed by internal medicine for, 44 (27.3%) and Obstetrics and Gynaecology for, 29 (18.0%]), However 18 (11.2%) did not specify their career of choice. The basic science fields such as anesthesiology, and oncology were the least favored choices by the students. The main reasons that influenced the students' decisions to opt for a particular specialty were inspiration during their clinical practicein 67 (41.6%). Financial reward (24.2%), dedication to the field (19.2%) possession of competency needed for the speciality (18.6%) and Influence of teacher (16.1%) were also factors that influenced future choice of speciality of the students. The majority of medical students preferred to pursue their specialty training. As the number and interest in certain specialties is huge, training centers must be ready to cater for the interests shown by the students. The lack of interest towards certain specialists such as basic sciences, anesthesiology, and oncology requires a special attention by policy makers.

"Choice Set" for health behavior in choice-constrained settings to frame research and inform policy: examples of food consumption, obesity and food security.

PubMed

Dover, Robert V H; Lambert, Estelle V

2016-03-16

Using the nexus between food consumption, food security and obesity, this paper addresses the complexity of health behavior decision-making moments that reflect relational social dynamics in context-specific dialogues, often in choice-constrained conditions. A pragmatic review of literature regarding social determinants of health in relation to food consumption, food security and obesity was used to advance this theoretical model. We suggest that health choice, such as food consumption, is based on more than the capacity and volition of individuals to make "healthy" choices, but is dialogic and adaptive. In terms of food consumption, there will always be choice-constrained conditions, along a continuum representing factors over which the individual has little or no control, to those for which they have greater agency. These range from food store geographies and inventories and food availability, logistical considerations such as transportation, food distribution, the structure of equity in food systems, state and non-government food and nutrition programs, to factors where the individual exercises a greater degree of autonomy, such as sociocultural foodways, family and neighborhood shopping strategies, and personal and family food preferences. At any given food decision-making moment, many factors of the continuum are present consciously or unconsciously when the individual makes a decision. These health behavior decision-making moments are mutable, whether from an individual perspective, or within a broader social or policy context. We review the construct of "choice set", the confluence of factors that are temporally weighted by the differentiated and relationally-contextualized importance of certain factors over others in that moment. The choice transition represents an essential shift of the choice set based on the conscious and unconscious weighting of accumulated evidence, such that people can project certain outcomes. Policies and interventions should avoid

Common factor analysis versus principal component analysis: choice for symptom cluster research.

PubMed

Kim, Hee-Ju

2008-03-01

The purpose of this paper is to examine differences between two factor analytical methods and their relevance for symptom cluster research: common factor analysis (CFA) versus principal component analysis (PCA). Literature was critically reviewed to elucidate the differences between CFA and PCA. A secondary analysis (N = 84) was utilized to show the actual result differences from the two methods. CFA analyzes only the reliable common variance of data, while PCA analyzes all the variance of data. An underlying hypothetical process or construct is involved in CFA but not in PCA. PCA tends to increase factor loadings especially in a study with a small number of variables and/or low estimated communality. Thus, PCA is not appropriate for examining the structure of data. If the study purpose is to explain correlations among variables and to examine the structure of the data (this is usual for most cases in symptom cluster research), CFA provides a more accurate result. If the purpose of a study is to summarize data with a smaller number of variables, PCA is the choice. PCA can also be used as an initial step in CFA because it provides information regarding the maximum number and nature of factors. In using factor analysis for symptom cluster research, several issues need to be considered, including subjectivity of solution, sample size, symptom selection, and level of measure.

The relationship between children's sensitivity to dominant and non-dominant patterns of lexical stress and reading accuracy.

Arciuli, Joanne

2017-05-01

This study reports on a new task for assessing children's sensitivity to lexical stress for words with different stress patterns and demonstrates that this task is useful in examining predictors of reading accuracy during the elementary years. In English, polysyllabic words beginning with a strong syllable exhibit the most common or dominant pattern of lexical stress (e.g., "coconut"), whereas polysyllabic words beginning with a weak syllable exhibit a less common non-dominant pattern (e.g., "banana"). The new Aliens Talking Underwater task assesses children's ability to match low-pass filtered recordings of words to pictures of objects. Via filtering, phonetic detail is removed but prosodic contour information relating to lexical stress is retained. In a series of two-alternative forced choice trials, participants see a picture and are asked to choose which of two filtered recordings matches the name of that picture; one recording exhibits the correct lexical stress of the target word, and the other recording reverses the pattern of stress over the initial two syllables of the target word rendering it incorrect. Target words exhibit either dominant stress or non-dominant stress. Analysis of data collected from 192 typically developing children aged 5 to 12years revealed that sensitivity to non dominant lexical stress was a significant predictor of reading accuracy even when age and phonological awareness were taken into account. A total of 76.3% of variance in children's reading accuracy was explained by these variables. Crown Copyright © 2016. Published by Elsevier Inc. All rights reserved.

Food deserts are thought to be a barrier to making healthier food choices. This concept has been challenged. The interaction between the physical environment and children's food choice has received little attention. The present study used food intake data to generate hypotheses concerning the role of the physical environment in food choice. A cross-sectional analysis was conducted of the dietary habits of Year 5 (9-10-year-old) children from 90 of Liverpool's 118 primary schools. Individuals with the 'best' and 'worst' food choices were mapped and two areas associated with these extreme choices located. One thousand five hundred and thirty-five children completed the dietary questionnaire and supplied a full and valid postcode. Two adjacent areas with relatively large numbers of children in the 'best' and 'worst' food choice groups were chosen. Both areas had very similar socio-economic profiles. The contrast in the physical environments was striking, even on visual inspection. Food deserts as a cause of poor food choice did not stand scrutiny; the area located by the worst food choices had a plethora of shops selling food (better termed a food prairie), whereas the area located by the best food choices had no shops in evidence but did have more 'space'.

Factors affecting choice of a healthy lifestyle: implications for nurses.

PubMed

Ochieng, Bertha M N

2006-02-01

Living a healthy lifestyle still remains a challenge to a wide section of the population. This article argues that since a healthy lifestyle is associated with other aspects of economic and social life, it should be examined within this context. This perspective suggests that participation in a healthy lifestyle, with its behavioural emphasis, which typically involves decisions about food, exercise, smoking, alcohol, drug use, risk of infection and accidents, is not necessarily up to the individual. Socioeconomic status, level of education, family, kin and social networks, gender, age and interpersonal influences all affect the choice of lifestyle. This has implications for community practitioners working in the field of health promotion, in particular to promote healthy lifestyle. A correlation model is presented that can be used by practitioners to identity factors that should be taken into consideration when working with clients to enable them to make a healthy lifestyle the easier option.

To investigate whether general psychological motivating factors that guide career selection of a medical specialty differ over the course of medical school and to compare differences in motivating factors among students choosing "controllable" lifestyle specialties, students choosing "uncontrollable" lifestyle specialties, and a cohort of radiology residents. An anonymous survey was distributed to first- through fourth-year medical students and radiology residents at a single institution. Participants were asked to select their top three of seven factors that most influenced their choice of medical specialty. Fourth-year students were asked to designate the specialty to which they had applied. The survey was distributed to 259 students and 47 radiology residents with a response rate of 93.8% (243 of 259) and 95.7% (45 of 47), respectively. The top three factors indicated by medical students were finding the daily work fulfilling, work-life balance, and interest in the subject. These top three factors were common to all medical student classes and did not differ between students choosing "controllable" versus "uncontrollable" fields. The factors uncommonly selected were similar personality to others in the field, attending income, competitiveness or prestige, and job market conditions. For radiology residents, the top three motivating factors were the same as for medical students. Three out of seven motivating factors were universally important to trainees, regardless of their stage of medical training or their selection of a controllable versus uncontrollable lifestyle specialty. These data suggest the variety of career choices made by students may not derive from differing underlying values. Copyright © 2018 American College of Radiology. Published by Elsevier Inc.

Little is known about the disparity of choices between three urinary diversions after radical cystectomy, focusing on patient and institutional factors. We identified urothelial carcinoma patients who received radical cystectomy with cutaneous ureterostomy, ileal conduit or continent reservoir using the Japanese Diagnosis Procedure Combination database from 2007 to 2012. Data comprised age, sex, comorbidities (converted into the Charlson index), TNM classification (converted into oncological stage), hospitals' academic status, hospital volume, bed volume and geographical region. Multivariate ordinal logistic regression analyses fitted with the proportional odds model were performed to analyze factors affecting urinary diversion choices. For dependent variables, the three diversions were converted into an ordinal variable in order of complexity: cutaneous ureterostomy (reference), ileal conduit and continent reservoir. Geographical variations were also examined by multivariate logistic regression models. A total of 4790 patients (1131 cutaneous ureterostomies [23.6 %], 2970 ileal conduits [62.0 %] and 689 continent reservoirs [14.4 %]) were included. Ordinal logistic regression analyses showed that male sex, lower age, lower Charlson index, early tumor stage, higher hospital volume (≥3.4 cases/year) and larger bed volume (≥450 beds) were significantly associated with the preference of more complex urinary diversion. Significant geographical disparity was also found. Good patient condition and early oncological status, as well as institutional factors, including high hospital volume, large bed volume and specific geographical regions, are independently related to the likelihood of choosing complex diversions. Recognizing this disparity would help reinforce the need for clinical practice uniformity.

Chronic psychosocial stress produces an array of adverse health consequences that are highly comorbid, including emotional eating, affective disorders, and metabolic syndrome. The consumption of high caloric diets (HCDs) is thought to provide comfort in the face of unrelenting psychosocial stress. Using social subordination in female rhesus monkeys as a model of continual exposure to daily stressors in women, we tested the hypothesis that subordinate females would consume significantly more calories from a HCD compared to dominant females, and this pattern of food intake would be associated with reduced cortisol release and reduced frequency of anxiety-like behaviors. Food intake, parameters of cortisol secretion, and socio-emotional behavior were assessed for 3 weeks during a no choice phase when only a low caloric diet (LCD) was available and during a choice condition when both a LCD and HCD were available. While all animals preferred the HCD, subordinate females consumed significantly more of the HCD than did dominant females. A flattening of the diurnal cortisol rhythm and a greater increase in serum cortisol to an acute social separation occurred during the diet choice condition in all females. Furthermore, the rate of anxiety-like behavior progressively declined during the 3-week choice condition in subordinate but not dominant females. These data provide support for the hypothesis that daily exposure to psychosocial stress increases consumption of calorically dense foods. Furthermore, consumption of HCDs may be a metabolic stressor that synergizes with the psychosocial stress of subordination to further increase the consumption of these diets.

Objective To analyze the factors influencing behavior of women in choosing contraceptive methods. Material and Methods A total of 4022 women who were admitted to our clinic in a year, were the subjects in this current study for contraception choices. Relationship between the current contraceptive choice and the age, marital status, educational level, gravidity and induced abortions were evaluated. Results Current users of any contraceptive methods were found to make up thirty-three percent of the entire study population. The most preferred method of contraception was an intrauterine device (46.4%), followed by, condom (19.2%), coitus interruptus (16.4%), tubal sterilization (11%), oral contraceptives (5.7%) and lastly the “other methods” that consisted of depot injectables and implants (1.2%). Among other contraceptive methods, the condom was found to be used mostly by the younger age group (OR:0.956, 95% CI:0.936–0.976, p<0.001), while tubal sterilization was preferred mainly by the elderly population (p<0.001, OR:1.091, 95% CI:1.062–1.122). Women that have a higher educational level, were found to use OC (76.3%, OR:5.970, 95% CI:3.233–11.022), tubal sterilization (59.6%, OR:4.110, 95% CI:2.694–6.271) and other methods (62.5%, OR:3.279, 95% CI:1.033–10.402) more commonly than the low educational group (p<0.001). Conclusion These results demonstrated that the rates of both contraception utilization and the usage of more effective methods of contraception need to be increased by providing better family planning systems and counselling opportunities.

Choices and changes: Eccles' Expectancy-Value model and upper-secondary school students' longitudinal reflections about their choice of a STEM education

NASA Astrophysics Data System (ADS)

Lykkegaard, Eva; Ulriksen, Lars

2016-03-01

During the past 30 years, Eccles' comprehensive social-psychological Expectancy-Value Model of Motivated Behavioural Choices (EV-MBC model) has been proven suitable for studying educational choices related to Science, Technology, Engineering and/or Mathematics (STEM). The reflections of 15 students in their last year in upper-secondary school concerning their choice of tertiary education were examined using quantitative EV-MBC surveys and repeated qualitative interviews. This article presents the analyses of three cases in detail. The analytical focus was whether the factors indicated in the EV-MBC model could be used to detect significant changes in the students' educational choice processes. An important finding was that the quantitative EV-MBC surveys and the qualitative interviews gave quite different results concerning the students' considerations about the choice of tertiary education, and that significant changes in the students' reflections were not captured by the factors of the EV-MBC model. This questions the validity of the EV-MBC surveys. Moreover, the quantitative factors from the EV-MBC model did not sufficiently explain students' dynamical educational choice processes where students in parallel considered several different potential educational trajectories. We therefore call for further studies of the EV-MBC model's use in describing longitudinal choice processes and especially in investigating significant changes.

Industrial production of clotting factors: Challenges of expression, and choice of host cells.

PubMed

Kumar, Sampath R

2015-07-01

The development of recombinant forms of blood coagulation factors as safer alternatives to plasma derived factors marked a major advance in the treatment of common coagulation disorders. These are complex proteins, mostly enzymes or co-enzymes, involving multiple post-translational modifications, and therefore are difficult to express. This article reviews the nature of the expression challenges for the industrial production of these factors, vis-à-vis the translational and post-translational bottlenecks, as well as the choice of host cell lines for high-fidelity production. For achieving high productivities of vitamin K dependent proteins, which include factors II (prothrombin), VII, IX and X, and protein C, host cell limitation of γ-glutamyl carboxylation is a major bottleneck. Despite progress in addressing this, involvement of yet unidentified protein(s) impedes a complete cell engineering solution. Human factor VIII expresses at very low levels due to limitations at several steps in the protein secretion pathway. Protein and cell engineering, vector improvement and alternate host cells promise improvement in the productivity. Production of Von Willebrand factor is constrained by its large size, complex structure, and the need for extensive glycosylation and disulfide-bonded oligomerization. All the licensed therapeutic factors are produced in CHO, BHK or HEK293 cells. While HEK293 is a recent adoption, BHK cells appear to be disfavored. Copyright © 2015 WILEY-VCH Verlag GmbH & Co.

Background and Aims: Working conditions are an important health determinant. Employment factors can negatively affect mental health (MH), but there is little research on MH risk factors in male-dominated industries (MDI). Method: A systematic review of risk factors for anxiety and depression disorders in MDI was undertaken. MDI comprised ≥ 70% male workers and included agriculture, construction, mining, manufacturing, transport and utilities. Major electronic databases (CINAHL, Cochrane Library, Informit, PsycINFO, PubMed and Scopus) were searched. Each study was categorised according to National Health and Medical Research Council's hierarchy of evidence and study quality was assessed according to six methodological criteria. Results: Nineteen studies met the inclusion criteria. Four categories of risk were identified: individual factors, team environment, work conditions and work–home interference. The main risk factors associated with anxiety and depression in MDI were poor health and lifestyles, unsupportive workplace relationships, job overload and job demands. Some studies indicated a higher risk of anxiety and depression for blue-collar workers. Conclusion: Substantial gaps exist in the evidence. Studies with stronger methodologies are required. Available evidence suggests that comprehensive primary, secondary and tertiary prevention approaches to address MH risk factors in MDI are necessary. There is a need for organisationally focused workplace MH policies and interventions. PMID:25750830

Understanding the motives for food choice in Western Balkan Countries.

2012-02-01

Substantial empirical evidence exists regarding the importance of different factors underlying food choice in Western Europe. However, research results on eating habits and food choice in the Western Balkan Countries (WBCs) remain scarce. A Food Choice Questionnaire (FCQ), an instrument that measures the reported importance of nine factors underlying food choice, was administered to a representative sample of 3085 adult respondents in six WBCs. The most important factors reported are sensory appeal, purchase convenience, and health and natural content; the least important are ethical concern and familiarity. The ranking of food choice motives across WBCs was strikingly similar. Factor analysis revealed eight factors compared to nine in the original FCQ model: health and natural content scales loaded onto one factor as did familiarity and ethical concern; the convenience scale items generated two factors, one related to purchase convenience and the other to preparation convenience. Groups of consumers with similar motivational profiles were identified using cluster analysis. Each cluster has distinct food purchasing behavior and socio-economic characteristics, for which appropriate public health communication messages can be drawn. Copyright © 2011 Elsevier Ltd.

Puertas, E Benjamín; Arósquipa, Carlos; Gutiérrez, Daniela

2013-11-01

To determine which factors influence a medical student's decision to choose a career in primary care; and to establish if these factors are similar or different among students in high-, middle- and low-income countries. An extensive search was done of PubMed, Google Scholar, and Virtual Library of Health for articles on primary care careers published in 2003-2013 in English, Spanish, and/or Portuguese. Initially, 600 records were identified; 74 full-text articles were assessed for eligibility and 55 were selected (42 from high-income countries; 13 from middle- and low-income). These were assessed to identify intrinsic and extrinsic factors that influence career choice among medical students from high-, middle-, and low-income countries. A comparison framework with common and specific factors that influence career choice in primary care among medical students from high-, middle- and low-income was developed. Factors were classified as extrinsic or intrinsic, and as facilitators or barriers. Several factors common to all countries were identified: facilitators were exposure to rural location, role models, working conditions; barriers were low income, prestige, and medical school environment. Some factors specific to middle- and low-income countries were: understanding of rural needs and intellectual challenge. Other factors specific to high-income countries were: attitude towards social problems, voluntary work, influence of family, and length of residency. Further studies on the subject are needed, especially in low- and middle-income countries. Identifying factors as barriers or facilitators for career choice will promote a better understanding of the reasons behind the shortage of primary care professionals and will contribute to policy building, improved training, and recruitment and retention of these professionals.

Selective attention to signs of success: social dominance and early stage interpersonal perception.

Maner, Jon K; DeWall, C Nathan; Gailliot, Matthew T

2008-04-01

Results from two experiments suggest that observers selectively attend to male, but not female, targets displaying signs of social dominance. Participants overestimated the frequency of dominant men in rapidly presented stimulus arrays (Study 1) and visually fixated on dominant men in an eyetracking experiment (Study 2). When viewing female targets, participants attended to signs of physical attractiveness rather than social dominance. Findings fit with evolutionary models of mating, which imply that dominance and physical attractiveness sometimes tend to be prioritized preferentially in judgments of men versus women, respectively. Findings suggest that sex differences in human mating are observed not only at the level of overt mating preferences and choices but also at early stages of interpersonal perception. This research demonstrates the utility of examining early-in-the-stream social cognition through the functionalist lens of adaptive thinking.

Regulation of illegal bushmeat trade is a major conservation challenge in Africa. We investigated what factors are most likely to induce actors in the bushmeat trade to shift to an alternative occupation by conducting a choice experiment with 325 actors in the bushmeat trade in the Kilombero Valley, Tanzania. Specifically, we asked respondents to choose between hunting or trading bushmeat and alternative salary-paying work, in a set of hypothetical scenarios where the attributes of these alternatives were varied and included measures of command and control, price of substitute meat, daily salary in the work option, and whether or not cows were donated to the respondent. We modeled the choice contingent on socioeconomic characteristics. The magnitude of fines and patrolling frequency had a significant but very low negative effect on the probability of choosing to engage in hunting or trading bushmeat compared with the salary of an alternative occupation. Donation of livestock and the price of substitute meats in the local market both affected the choice significantly in a negative and a positive direction, respectively. The wealthier a household was the more likely the respondent was to choose to continue hunting or trading bushmeat. On the margin, our results suggest that given current conditions in the Kilombero Valley on any given day 90% of the respondents would choose salary work at US$3.37/day over their activities in the bushmeat trade, all else equal. © 2013 Society for Conservation Biology.

Biological soil crusts (BSCs) cover >35% of the Earth's land area and contribute to important ecological functions in arid and semiarid ecosystems, including erosion reduction, hydrological cycling, and nutrient cycling. Artificial rapid cultivation of BSCs can provide a novel alternative to traditional biological methods for controlling soil and water loss such as the planting of trees, shrubs, and grasses. At present, little is known regarding the cultivation of BSCs in the field due to lack of knowledge regarding the influencing factors that control BSCs growth. Thus, we determined the effects of various environmental factors (shade; watering; N, P, K, and Ca concentrations) on the growth of cyanobacteria-dominated BSCs from the Sonoran Desert in the southwestern United States. The soil surface changes and chlorophyll a concentrations were used as proxies of BSC growth and development. After 4 months, five factors were found to impact BSC growth with the following order of importance: NH4NO3 ≈ watering frequency>shading>CaCO3 ≈ KH2PO4. The soil water content was the primary positive factor affecting BSC growth, and BSCs that were watered every 5 days harbored greater biomass than those watered every 10 days. Groups that received NH4NO3 consistently exhibited poor growth, suggesting that fixed N amendment may suppress BSC growth. The effect of shading on the BSC biomass was inconsistent and depended on many factors including the soil water content and availability of nutrients. KH2PO4 and CaCO3 had nonsignificant effects on BSC growth. Collectively, our results indicate that the rapid restoration of BSCs can be controlled and realized by artificial "broadcasting" cultivation through the optimization of environmental factors.

A national sample of PhD-trained scientists completed training, accepted subsequent employment in academic and nonacademic positions, and were queried about their previous graduate training and current employment. Respondents indicated factors contributing to their employment decision (e.g., working conditions, salary, job security). The data indicate the relative importance of deciding factors influencing career choice, controlling for gender, initial interest in faculty careers, and number of postgraduate publications. Among both well-represented (WR; n = 3444) and underrepresented minority (URM; n = 225) respondents, faculty career choice was positively associated with desire for autonomy and partner opportunity and negatively associated with desire for leadership opportunity. Differences between groups in reasons endorsed included: variety, prestige, salary, family influence, and faculty advisor influence. Furthermore, endorsement of faculty advisor or other mentor influence and family or peer influence were surprisingly rare across groups, suggesting that formal and informal support networks could provide a missed opportunity to provide support for trainees who want to stay in faculty career paths. Reasons requiring alteration of misperceptions (e.g., limited leadership opportunity for faculty) must be distinguished from reasons requiring removal of actual barriers. Further investigation into factors that affect PhDs’ career decisions can help elucidate why URM candidates are disproportionately exiting the academy. PMID:27587854

This paper has two aims. First, we investigate how often people make choices conforming to Bayes' rule when natural sampling is applied. Second, we show that using Bayes' rule is not necessary to make choices satisfying Bayes' rule. Simpler methods, even fallacious heuristics, might prescribe correct choices reasonably often under specific circumstances. We considered elementary situations with binary sets of hypotheses and data. We adopted an ecological approach and prepared two-stage computer tasks resembling natural sampling. Probabilistic relations were inferred from a set of pictures, followed by a choice which was made to maximize the chance of a preferred outcome. Use of Bayes' rule was deduced indirectly from choices. Study 1 used a stratified sample of N = 60 participants equally distributed with regard to gender and type of education (humanities vs. pure sciences). Choices satisfying Bayes' rule were dominant. To investigate ways of making choices more directly, we replicated Study 1, adding a task with a verbal report. In Study 2 (N = 76) choices conforming to Bayes' rule dominated again. However, the verbal reports revealed use of a new, non-inverse rule, which always renders correct choices, but is easier than Bayes' rule to apply. It does not require inversion of conditions [transforming P(H) and P(D|H) into P(H|D)] when computing chances. Study 3 examined the efficiency of three fallacious heuristics (pre-Bayesian, representativeness, and evidence-only) in producing choices concordant with Bayes' rule. Computer-simulated scenarios revealed that the heuristics produced correct choices reasonably often under specific base rates and likelihood ratios. Summing up we conclude that natural sampling results in most choices conforming to Bayes' rule. However, people tend to replace Bayes' rule with simpler methods, and even use of fallacious heuristics may be satisfactorily efficient.

Relatively little is known regarding factors associated with the choice of a research career among practicing physicians, and most investigations of this issue have been conducted in the absence of a theoretical/conceptual model. Therefore we designed a survey to identify the determinants of decisions to pursue a biomedical research career based upon the Theory of Planned Behavior and the concept of stereotype threat. From October 2012 through January 2014 electronic surveys were sent to four consecutive Harvard Medical School graduating classes, 1996-1999. Respondents provided demographic information, indicated their current research involvement, and provided retrospective reports of their experiences and attitudes when they were making career choices as they completed medical school. Multivariable ordinal regression was used to identify factors independently associated with current research involvement. Completed questionnaires were received from 358 respondents (response rate 65%). In unadjusted analyses, variables associated with more extensive research involvement included non-minority status, male gender, lower debt at graduation, strong attitudes toward research at time of graduation, and greater social pressures to pursue research (all P<.001). These associations remained significant in multivariable regression analysis (all P<0.01). However, an interaction between sex and prior research publications was also detected, indicating that more extensive research involvement during medical school doubled the likelihood of a research career for women (OR 2.53, 95%CI 1.00-6.40; P=0.05). Most of the factors predicting research career choice involve factors that are potentially modifiable, suggesting that appropriately designed behavioral interventions may help to expand the size and diversity of the biomedical research community.

Chance, choice, and the future of reproduction.

PubMed

Miller, W B

1983-11-01

The evolution of reproduction has been characterized by the development of complex biological and behavioral mechanisms that serve to regulate chance events. Human reproduction has been characterized by the increasing importance of individual choice. Some contemporary manifestations of this broad trend are the high incidence of contraceptive and "proceptive" behavior among couples in Western, industrialized nations. The former behavior willingly attempts to prevent conception while the latter actively attempts to induce conception (such as concentrating intercourse around the time of ovulation). Both patterns of behavior indicate that a choice is being made. A 3-year study of 1000 women revealed proceptive behavior as the most important factor predicting occurance of conception among married couples in the United States. The general strategeis people follow while making childbearing decisions: termination, sequencing, and pre-planning form a continuum following the historical trend toward greater reproductive control. In the terminating strategy, a couple makes no decision about child bearing until the number of children they have become enough or too much. In the sequencing strategy, decisions to have children are made 1 child at a time until a satisfactory limit is reached. In the pre-planning strategy, a plan is worked out ahead of time and is subsequently carried out. As new reproductive technology is introduced and as progressive change is made in society's reproductive related values and beliefs, choice will continue to dominate chance as the highly likely trend for the future of reproduction. Surrogate maternity is just 1 example of this trend. However, these new options, which culminate in the theory and practice of "progensis," (still in its infancy), as well as offering a rich opportunity, can also incur psychological burdens on a couple. Thus, as with any kind of freedom, these developments will require care, caution and responsibility.

Face judgments of dominance play an important role in human social interaction. Perceived facial dominance is thought to indicate physical formidability, as well as resource acquisition and holding potential. Dominance cues in the face affect perceptions of attractiveness, emotional state, and physical strength. Most experimental paradigms test perceptions of facial dominance in individual faces, or they use manipulated versions of the same face in a forced-choice task but in the absence of other faces. Here, we extend this work by assessing whether dominance ratings are absolute or are judged relative to other faces. We presented participants with faces to be rated for dominance (target faces), while also presenting a second face (non-target faces) that was not to be rated. We found that both the masculinity and sex of the non-target face affected dominance ratings of the target face. Masculinized non-target faces decreased the perceived dominance of a target face relative to a feminized non-target face, and displaying a male non-target face decreased perceived dominance of a target face more so than a female non-target face. Perceived dominance of male target faces was affected more by masculinization of male non-target faces than female non-target faces. These results indicate that dominance perceptions can be altered by surrounding faces, demonstrating that facial dominance is judged at least partly relative to other faces.

Fetal Monitoring: Creating a Culture of Safety With Informed Choice

The dominant culture in labor and birth is the medical model, not the midwifery model of woman-centered care. Consensus among professional and governmental groups is that, based on the evidence, intermittent auscultation is safer to use in healthy women with uncomplicated pregnancies than electronic fetal monitoring (EFM). Barriers impact the laboring woman’s ability to give informed choice regarding fetal monitoring. Lack of informed choice denies a woman her right to be in control of her birth experience, and is in opposition to a woman’s right to autonomy and self-determination. PMID:24868127

Survey that was created based on a comprehensive literature review to determine which factors are considered important when choosing practice specialty. Ontario medical school. An open cohort of medical students in the graduating classes of 2008 to 2011 (inclusive). The main factors that influenced participants' decision to choose a career in primary care or pediatrics, and the main factors that influenced participants' decision to choose a career in a non-front-line specialty. A total of 323 participants were included in this study. Factors that significantly influenced participants' career choice in family medicine or pediatrics involved work-life balance (acceptable hours of practice [ P = .005], acceptable on-call demands [ P = .012], and lifestyle flexibility [ P = .006]); a robust physician-patient relationship (ability to promote individual health promotion [ P = .014] and the opportunity to form long-term relationships [ P  < .001], provide comprehensive care [ P = .001], and treat patients and their families [ P = .006]); and duration of residency program ( P = .001). The career-related factors that significantly influenced participants' decision to choose a non-front-line specialty were as follows: becoming an expert ( P  < .001), maintaining a focused scope of practice ( P  < .001), having a procedure-focused practice ( P = .001), seeing immediate results from one's actions ( P  < .001), potentially earning a high income ( P  < .001), and having a perceived status among colleagues ( P  < .001). In this study, 8 factors were found to positively influence medical students' career choice in family medicine and pediatrics, and 6 factors influenced the decision to choose a career in a non-front-line specialty.

Selfish routing equilibrium in stochastic traffic network: A probability-dominant description.

PubMed

Zhang, Wenyi; He, Zhengbing; Guan, Wei; Ma, Rui

2017-01-01

This paper suggests a probability-dominant user equilibrium (PdUE) model to describe the selfish routing equilibrium in a stochastic traffic network. At PdUE, travel demands are only assigned to the most dominant routes in the same origin-destination pair. A probability-dominant rerouting dynamic model is proposed to explain the behavioral mechanism of PdUE. To facilitate applications, the logit formula of PdUE is developed, of which a well-designed route set is not indispensable and the equivalent varitional inequality formation is simple. Two routing strategies, i.e., the probability-dominant strategy (PDS) and the dominant probability strategy (DPS), are discussed through a hypothetical experiment. It is found that, whether out of insurance or striving for perfection, PDS is a better choice than DPS. For more general cases, the conducted numerical tests lead to the same conclusion. These imply that PdUE (rather than the conventional stochastic user equilibrium) is a desirable selfish routing equilibrium for a stochastic network, given that the probability distributions of travel time are available to travelers.

Optometry is a primary health-care profession (PHCP) and this study aimed to elucidate the factors influencing the choice of optometry as a career for Saudi students, the students' perceptions of optometry and the effect of gender. Two hundred and forty-seven students whose average age was 21.7 ± 1.5 (SD) years and who are currently enrolled in two colleges of optometry in Saudi Arabia--King Saud University (KSU) and Qassim University (QU)--completed self-administered questionnaires. The survey included questions concerning demography, career first choice, career perception and factors influencing career choices. The response rate was 87.6 per cent and there were 161 male (64.9 per cent) students. Seventy-nine per cent of the participants were from KSU (males and females) and 20.6 per cent were from QU (only males). Seventy-three per cent come from Riyadh and 19 per cent are from Qassim province. Regarding the first choice for their careers, the females (92 per cent) were 0.4 times more likely (p = 0.012) to choose optometry than males (78.3 per cent). The males were significantly more likely to be influenced by the following factors: the Doctor of Optometry (OD) programs run at both universities, good salary and prospects (p < 0.05, for all). The women were significantly less likely to be influenced by another individual (p = 0.0004). Generally, more than two-thirds of the respondents viewed the desire to help others, professional prestige and the new OD programs as the three most influential factors in opting for a career in optometry. Females were more likely to opt for a career in optometry and males were more likely to be influenced by the new OD programs, good salary and job prospects. Service provision to others in the community was a primary motivation to opt for a career in optometry among young Saudis. © 2014 The Authors.

Individuals undertaking a weight loss effort have a choice among proven dietary approaches. Factors contributing to choice of either a low-fat/low-calorie diet or a low-carbohydrate diet, two of the most studied and popular dietary approaches, are unknown. The current study used data from participants randomized to the 'choice' arm of a trial examining whether being able to choose a diet regimen yields higher weight loss than being randomly assigned to a diet. At study entry, participants attended a group session during which they were provided tailored feedback indicating which diet was most consistent with their food preferences using the Geiselman Food Preference Questionnaire (FPQ), information about both diets, and example meals for each diet. One week later, they indicated which diet they chose to follow during the 48-week study, with the option of switching diets after 12 weeks. Of 105 choice arm participants, 44 (42%) chose the low-fat/low-calorie diet and 61 (58%) chose the low-carbohydrate diet. In bivariate analyses, diet choice was not associated with age, race, sex, education, BMI, or diabetes (all p > 0.05). Low-carbohydrate diet choice was associated with baseline higher percent fat intake (p = 0.007), lower percent carbohydrate intake (p = 0.02), and food preferences consistent with a low-carbohydrate diet according to FPQ (p < 0.0001). In a multivariable logistic regression model, only FPQ diet preference was associated with diet choice (p = 0.001). Reported reasons for diet choice were generally similar for those choosing either diet; however, concerns about negative health effects of the unselected diet was rated as more influential among participants selecting the low-fat diet. Only three low-carbohydrate and two low-fat diet participants switched diets at 12 weeks. Results suggest that when provided a choice between two popular weight loss dietary approaches, an individual's selection is likely influenced by baseline dietary

Computational Precision of Mental Inference as Critical Source of Human Choice Suboptimality.

PubMed

Drugowitsch, Jan; Wyart, Valentin; Devauchelle, Anne-Dominique; Koechlin, Etienne

2016-12-21

Making decisions in uncertain environments often requires combining multiple pieces of ambiguous information from external cues. In such conditions, human choices resemble optimal Bayesian inference, but typically show a large suboptimal variability whose origin remains poorly understood. In particular, this choice suboptimality might arise from imperfections in mental inference rather than in peripheral stages, such as sensory processing and response selection. Here, we dissociate these three sources of suboptimality in human choices based on combining multiple ambiguous cues. Using a novel quantitative approach for identifying the origin and structure of choice variability, we show that imperfections in inference alone cause a dominant fraction of suboptimal choices. Furthermore, two-thirds of this suboptimality appear to derive from the limited precision of neural computations implementing inference rather than from systematic deviations from Bayes-optimal inference. These findings set an upper bound on the accuracy and ultimate predictability of human choices in uncertain environments. Copyright © 2016 Elsevier Inc. All rights reserved.

Determinants of choice, and vulnerability and recovery in addiction

PubMed Central

Lamb, R.J.; Maguire, David R.; Ginsburg, Brett C.; Pinkston, Jonathan W.; France, Charles P.

2016-01-01

Addiction may be viewed as choice governed by competing contingencies. One factor impacting choice, particularly as it relates to addiction, is sensitivity to delayed rewards. Discounting of delayed rewards influences addiction vulnerability because of competition between relatively immediate gains of drug use, e.g. intoxication, versus relatively remote gains of abstinence, e.g. family stability. Factors modifying delay sensitivity can be modeled in the laboratory. For instance, increased delay sensitivity can be similarly observed in adolescent humans and non-human animals. Similarly, genetic factors influence delay sensitivity in humans and animals. Recovery from addiction may also be viewed as choice behavior. Thus, reinforcing alternative behavior facilitates recovery because reinforcing alternative behavior decreases the frequency of using drugs. How reinforcing alternative behavior influences recovery can also be modeled in the laboratory. For instance, relapse risk decreases as abstinence duration increases, and this decreasing risk can be modeled in animals using choice procedures. In summary, addiction in many respects can be conceptualized as a problem of choice. Animal models of choice disorders stand to increase our understanding of the core processes that establish and maintain addiction and serve as a proving ground for development of novel treatments.

In Germany, the patient himself makes the choice for or against a health service provider. Hospital comparison websites offer him possibilities to inform himself before choosing. However, it remains unclear, how health care consumers use those websites, and there is little information about how preferences in hospital choice differ interpersonally. We conducted a Discrete-Choice-Experiment (DCE) on hospital choice with 1500 randomly selected participants (age 40-70) in three different German cities selecting four attributes for hospital vignettes. The analysis of the study draws on multilevel mixed effects logit regression analyses with the dependent variables: "chance to select a hospital" and "choice confidence". Subsequently, we performed a Latent-Class-Analysis to uncover consumer segments with distinct preferences. 590 of the questionnaires were evaluable. All four attributes of the hospital vignettes have a significant impact on hospital choice. The attribute "complication rate" exerts the highest impact on consumers' decisions and reported choice confidence. Latent-Class-Analysis results in one dominant consumer segment that considered the complication rate the most important decision criterion. Using DCE, we were able to show that the complication rate is an important trusted criterion in hospital choice to a large group of consumers. Our study supports current governmental efforts in Germany to concentrate the provision of specialized health care services. We suggest further national and cross-national research on the topic.

Background This study examined the determinants of specialty choice of preresidency medical graduates in southeastern Nigeria. Methods We used a comparative cross-sectional survey of preresidency medical graduates who took the Basic Sciences Examination of the Postgraduate Medical College in Enugu, southeastern Nigeria, in March 2007. Data on participants' demographics and specialty selected, the timing of the decision, and factors in specialty selection were collected using a questionnaire. Data were examined using descriptive and analytical statistics. P < .05 was considered significant. Results The survey response rate was 90.8% (287 of 316). The sample included 219 men and 68 women, ranging in age from 24 to 53 years and with a mean age of 33.5 ± 1.1 (SD) years. Career choice was more frequently influenced by personal interest (66.6%), career prospects (9.1%), and appraisal of own skills/aptitudes (5.6%), and it was least affected by altruistic motives (1.7%) and influence of parents/relations (1.7%). The respondents selected specialties at different rates: obstetrics and gynecology (22.6%), surgery (19.6%), pediatrics (16.0%), anesthesiology (3.1%), psychiatry (0.3%), and dentistry (0.0%). Most (97.2%) participants had decided on specialty choice by the end of their fifth (of a total 16 years) postgraduate year. The participants significantly more frequently preferred surgery and pediatrics to other disciplines (P < .002, after Bonferroni correction for multiple comparisons). Conclusions Preresidency medical graduates in southeastern Nigeria were influenced by personal interest, career prospects, and personal skills/aptitude in deciding which specialty training to pursue. The most frequently chosen specialties were surgery and pediatrics. These findings have implications for Nigeria's education and health care policy makers. PMID:22942964

The present study investigated Korean and Taiwan adults on the importance of and the satisfaction with street food sanitation and street food choice factor, in order to present management and improvement measures for street foods. The present study conducted a survey on 400 randomly chosen adults (200 Korean, 200 Taiwanese). General characteristics, eating habits, street food intake frequency, and preference by type of street food of respondents were checked. Respondents' importance and satisfaction of street food hygiene and selection attributes were also measured. In order to test for the difference between groups, χ(2)-test and t-test were performed. ISA was also performed to analyze importance and satisfaction. Results showed that the importance of sanitation was significantly higher than satisfaction on all items in both Korea and Taiwan, and the satisfaction with sanitation was higher in Taiwan than in Korea. According to ISA results with street food sanitation, satisfaction was low while importance was high in both Korea and Taiwan. In terms of street food choice factor, importance scores were significantly higher than satisfaction scores on all items. In addition, satisfaction scores on all items except 'taste' were significantly higher in Taiwan than in Korea. A manual on sanitation management of street foods should be developed to change the knowledge and attitude toward sanitation by putting into practice a regularly conducted education. Considering the popularity of street foods and its potential as a tourism resource to easily publicize our food culture, thorough management measures should be prepared on sanitation so that safe street food culture should be created.

Relatively little is known regarding factors associated with the choice of a research career among practicing physicians, and most investigations of this issue have been conducted in the absence of a theoretical/conceptual model. Therefore we designed a survey to identify the determinants of decisions to pursue a biomedical research career based upon the Theory of Planned Behavior and the concept of stereotype threat. From October 2012 through January 2014 electronic surveys were sent to four consecutive Harvard Medical School graduating classes, 1996-1999. Respondents provided demographic information, indicated their current research involvement, and provided retrospective reports of their experiences and attitudes when they were making career choices as they completed medical school. Multivariable ordinal regression was used to identify factors independently associated with current research involvement. Completed questionnaires were received from 358 respondents (response rate 65 %). In unadjusted analyses, variables associated with more extensive research involvement included non-minority status, male gender, lower debt at graduation, strong attitudes toward research at time of graduation, and greater social pressures to pursue research (all P < .001). These associations remained significant in multivariable regression analysis (all P < 0.01). However, an interaction between sex and prior research publications was also detected, indicating that more extensive research involvement during medical school doubled the likelihood of a research career for women (OR 2.53, 95 % CI 1.00-6.40; P = 0.05). Most of the factors predicting research career choice involve factors that are potentially modifiable, suggesting that appropriately designed behavioral interventions may help to expand the size and diversity of the biomedical research community.

The objective of this study is to explore risk factors associated with overweight and high blood pressure in Chinese American children. Students and their parents were recruited from Chinese language schools in the San Francisco Bay Area. Data were collected on 67 children and their mothers, and included children's weight, height, waist and hip circumferences, blood pressure, level of physical activity, dietary intake, usual food choice, knowledge about nutrition and physical activity, and self-efficacy regarding diet and physical activity. Mothers completed questionnaires on demographic data and acculturation. About 46% of children had a body mass index exceeding the 85th percentile. Lower level of maternal acculturation is a risk factor for overweight and higher waist to hip ratio. Children's unhealthy food choices were predictive of high body mass index and high systolic blood pressure, whereas older age and less physical activity in children were predictors of high diastolic blood pressure. Developing culturally sensitive and developmentally appropriate interventions to reduce overweight and high blood pressure is critical to reduce health disparities among minority children.

In interspecific hybrids or allopolyploids, often one parental set of ribosomal RNA genes is transcribed and the other is silent, an epigenetic phenomenon known as nucleolar dominance. Silencing is enforced by cytosine methylation and histone deacetylation, but the initial discrimination mechanism is unknown. One hypothesis is that a species-specific transcription factor is inactivated, thereby silencing one set of rRNA genes. Another is that dominant rRNA genes have higher binding affinities for limiting transcription factors. A third suggests that selective methylation of underdominant rRNA genes blocks transcription factor binding. We tested these hypotheses using Brassica napus (canola), an allotetraploid derived from B. rapa and B. oleracea in which only B. rapa rRNA genes are transcribed. B. oleracea and B. rapa rRNA genes were active when transfected into protoplasts of the other species, which argues against the species-specific transcription factor model. B. oleracea and B. rapa rRNA genes also competed equally for the pol I transcription machinery in vitro and in vivo. Cytosine methylation had no effect on rRNA gene transcription in vitro, which suggests that transcription factor binding was unimpaired. These data are inconsistent with the prevailing models and point to discrimination mechanisms that are likely to act at a chromosomal level. PMID:10224274

The aim of the study was to analyse the psychometric properties of the Food Choice Questionnaire (FCQ) in Spanish population (FCQ-SP), its factor structure and internal consistency. In addition, the relationships between the FCQ-SP and the General Health Questionnaire (GHQ), the Irrational Food Beliefs Scale (IFBS), and the Eating Disorders Inventory-3 (EDI-3) were analysed in order to explore the validity of the FCQSP. Possible gender differences in the food choice pattern were analysed. The sample comprised 255 women and 50 men, ranged from 25 to 64 years. In order to get a better interpretation of the results associated with changes based on the age, the participants were grouped in four age intervals (25-34, 35-44, 45-54, and 55-64). All the participants were relatives of secondary and high school students in three schools of Seville and Cordoba. The factor analysis yields the seven following factors: mood, health and natural content, sensory appeal, weight control, convenience, familiarity, and price. The internal consistency was determined by means of the Cronbach's α coefficients, which ranged from 0.70 to 0.83 for the different components. With regards to the food choice profile, sensory appeal was the most motivating factor to choose food, followed by price and weight control. With respect to gender differences, women showed higher scores than men in all components except in the case of price. The FCQ-SP has adequate psychometric properties to be applied to Spanish population, and it is useful to explore the consumers' motivation with regards to food choice.

Determinants of choice, and vulnerability and recovery in addiction.

Lamb, R J; Maguire, David R; Ginsburg, Brett C; Pinkston, Jonathan W; France, Charles P

2016-06-01

Addiction may be viewed as choice governed by competing contingencies. One factor impacting choice, particularly as it relates to addiction, is sensitivity to delayed rewards. Discounting of delayed rewards influences addiction vulnerability because of competition between relatively immediate gains of drug use, e.g. intoxication, versus relatively remote gains of abstinence, e.g. family stability. Factors modifying delay sensitivity can be modeled in the laboratory. For instance, increased delay sensitivity can be similarly observed in adolescent humans and non-human animals. Similarly, genetic factors influence delay sensitivity in humans and animals. Recovery from addiction may also be viewed as choice behavior. Thus, reinforcing alternative behavior facilitates recovery because reinforcing alternative behavior decreases the frequency of using drugs. How reinforcing alternative behavior influences recovery can also be modeled in the laboratory. For instance, relapse risk decreases as abstinence duration increases, and this decreasing risk can be modeled in animals using choice procedures. In summary, addiction in many respects can be conceptualized as a problem of choice. Animal models of choice disorders stand to increase our understanding of the core processes that establish and maintain addiction and serve as a proving ground for development of novel treatments.

Factors influencing the surgery intentions and choices of women with early breast cancer: the predictive utility of an extended theory of planned behaviour

PubMed Central

2013-01-01

Background Women diagnosed with early breast cancer (stage I or II) can be offered the choice between mastectomy or breast conservation surgery with radiotherapy due to equivalence in survival rates. A wide variation in the surgical management of breast cancer and a lack of theoretically guided research on this issue highlight the need for further research into the factors influencing women’s choices. An extended Theory of Planned Behaviour (TPB) could provide a basis to understand and predict women’s surgery choices. The aims of this study were to understand and predict the surgery intentions and choices of women newly diagnosed with early breast cancer, examining the predictive utility of an extended TPB. Methods Sixty-two women recruited from three UK breast clinics participated in the study; 48 women, newly diagnosed with early breast cancer, completed online questionnaires both before their surgery and after accessing an online decision support intervention (BresDex). Questionnaires assessed views about breast cancer and the available treatment options using items designed to measure constructs of an extended TPB (i.e., attitudes, subjective norms, perceived behavioural control, and anticipated regret), and women’s intentions to choose mastectomy or BCS. Objective data were collected on women’s choice of surgery via the clinical breast teams. Multiple and logistic regression analyses examined predictors of surgery intentions and subsequent choice of surgery. Results The extended TPB accounted for 69.9% of the variance in intentions (p <.001); attitudes and subjective norms were significant predictors. Including additional variables revealed anticipated regret to be a more important predictor than subjective norms. Surgery intentions significantly predicted surgery choices (p <.01). Conclusions These findings demonstrate the utility of an extended TPB in predicting and understanding women’s surgery intentions and choices for early breast cancer

Task shifting from established health professionals to mid-level providers (MLPs) (professionals who undergo shorter training in specific procedures) is one key strategy for reducing maternal and neonatal deaths. This has resulted in a growth in cadre types providing obstetric care in low and middle-income countries. Little is known about the relative importance of the different factors in determining motivation and retention amongst these cadres. This paper presents findings from large sample (1972 respondents) discrete choice experiments to examine the employment preferences of obstetric care workers across three east African countries. The strongest predictors of job choice were access to continuing professional development and the presence of functioning human resources management (transparent, accountable and consistent systems for staff support, supervision and appraisal). Consistent with similar works we find pay and allowances significantly positively related to utility, but financial rewards are not as fundamental a factor underlying employment preferences as many may have previously believed. Location (urban vs rural) had the smallest average effect on utility for job choice in all three countries. These findings are important in the context where efforts to address the human resources crisis have focused primarily on increasing salaries and incentives, as well as providing allowances to work in rural areas.

[Choice of therapy based on clinical setting].

The choice of therapy in psoriasis is a complex multidimensional process based on both patient-related and disease-related factors. Standardisation of inclusion criteria for clinical trials leads to the exclusion of large numbers of patients with special forms of psoriasis or presenting comorbidities that must nevertheless be dealt with in real-life situations. The main patient-related factors affecting choice of therapy are age, pregnancy for women and the desire to father children for men, renal and hepatic failure, the risk of infection and neoplasia, metabolic and both cardiovascular and psychiatric comorbidities, as well as compliance and lifestyle. Disease-related factors affecting choice of therapy include unstable lesions, acral sites (palms, soles, nails, face and scalp), erythrodermic psoriasis, pustular psoriasis, guttate psoriasis and associated psoriatic rheumatism. The therapeutic recommendations set out in this study are based upon a critical analysis of the literature and upon the actual therapeutic practice of the experts.

Nepal is experiencing a public health issue similar to the rest of the world, i.e., the geographical maldistribution of physicians. Although there is some documentation about the reasons physicians elect to leave Nepal to work abroad, very little is known about the salient factors that influence the choice of an urban versus rural practice setting for those physicians who do not migrate. In recent years, around 1000 medical students became doctors within Nepal, but their distribution in rural locations is not adequate. The purpose of this study was to explore what factors influence the choice of urban or rural location for the future clinical practice of Nepalese medical students in the final year of their program A cross-sectional descriptive study design was used for this study involving Nepalese medical students in their final year of study and currently doing an internship in a medical college. The sample consisted of 393 medical students from four medical colleges in Nepal that were selected randomly. An anonymous self-administered questionnaire was used for data collection. To determine the association with rural location choice for their future practice setting, a comparison was done that involved demographic, socio-economic, and educational factors. Data were entered in EpiData and analyzed by using SPSS version 16. Among the 393 respondents, two thirds were male (66.9%) and more than half were below 25 years of age. Almost all (93%) respondents were single and about two thirds (63.4%) were of Brahmin and Chhetri ethnic origin. About two thirds (64.1%) of the respondents were born in a rural setting, and 58.8% and 53.3% had a place of rearing and permanent address in a rural location, respectively. The predictors of future rural location choice for their clinical practice (based on the bivariate analysis) included: (a) Rural (versus urban) place of birth, place of rearing, and permanent address (b) Source of family income (service, business, and agriculture

Space, agency, and withdrawal: birth control choices of women in Turkey.

Withdrawal (WD) is not a reliable method for preventing unwanted pregnancies, yet it is still a very popular form of birth control in many societies, including Turkey. We look at the relationship between women's agency and physical space in relation to birth control choices of women in Turkey. Agency in our context refers to a woman's ability to resist domination and subordination to the patriarchal beliefs valuing her reproductivity over her pleasure. Our analysis of the Turkish Demographic Health Survey (TDHS) suggests that (a) the available space in the household for possible private encounters between husband and wife, and (b) the women's capacity to insert her agency into her life choices are closely correlated with WD choices. Women with better social and physical resources prefer WD less.

To assess factors influencing infant-feeding methods selected by HIV-infected mothers. A descriptive quantitative study was conducted among 80 mothers with babies aged 0-6 months who were randomly selected and interviewed. Descriptive statistics were used to summarize the findings. Factors considered by women in choosing the infant-feeding methods included sociocultural acceptability (58.8%), feasibility and support from significant others (35%), knowledge of the selected method (55%), affordability (61.2%), implementation of the infant-feeding method without interference (62.5%), and safety (47.5%). Exclusive breast-feeding was the most preferred method of infant feeding. Disclosure of HIV status by a woman to her partner is a major condition for successful replacement feeding method, especially within the African cultural context. However, disclosure of HIV status to the partner was feared by most women as only 16.2% of the women disclosed their HIV status to partners. The factors considered by women in choosing the infant-feeding option were ability to implement the options without interference from significant others, affordability, and sociocultural acceptability. Knowledge of the selected option, its advantages and disadvantages, safety, and feasibility were also important factors. Nurses and midwives have to educate clients and support them in their choice of infant-feeding methods. © 2013 The Authors. Japan Journal of Nursing Science © 2013 Japan Academy of Nursing Science.

Control and Effort Costs Influence the Motivational Consequences of Choice

Sullivan-Toole, Holly; Richey, John A.; Tricomi, Elizabeth

2017-01-01

The act of making a choice, apart from any outcomes the choice may yield, has, paradoxically, been linked to both the enhancement and the detriment of intrinsic motivation. Research has implicated two factors in potentially mediating these contradictory effects: the personal control conferred by a choice and the costs associated with a choice. Across four experiments, utilizing a physical effort task disguised as a simple video game, we systematically varied costs across two levels of physical effort requirements (Low-Requirement, High-Requirement) and control over effort costs across three levels of choice (Free-Choice, Restricted-Choice, and No-Choice) to disambiguate how these factors affect the motivational consequences of choosing within an effortful task. Together, our results indicated that, in the face of effort requirements, illusory control alone may not sufficiently enhance perceptions of personal control to boost intrinsic motivation; rather, the experience of actual control may be necessary to overcome effort costs and elevate performance. Additionally, we demonstrated that conditions of illusory control, while otherwise unmotivating, can through association with the experience of free-choice, be transformed to have a positive effect on motivation.

Orbitofrontal cortical activity during repeated free choice.

Campos, Michael; Koppitch, Kari; Andersen, Richard A; Shimojo, Shinsuke

2012-06-01

Neurons in the orbitofrontal cortex (OFC) have been shown to encode subjective values, suggesting a role in preference-based decision-making, although the precise relation to choice behavior is unclear. In a repeated two-choice task, subjective values of each choice can account for aggregate choice behavior, which is the overall likelihood of choosing one option over the other. Individual choices, however, are impossible to predict with knowledge of relative subjective values alone. In this study we investigated the role of internal factors in choice behavior with a simple but novel free-choice task and simultaneous recording from individual neurons in nonhuman primate OFC. We found that, first, the observed sequences of choice behavior included periods of exceptionally long runs of each of two available options and periods of frequent switching. Neither a satiety-based mechanism nor a random selection process could explain the observed choice behavior. Second, OFC neurons encode important features of the choice behavior. These features include activity selective for exceptionally long runs of a given choice (stay selectivity) as well as activity selective for switches between choices (switch selectivity). These results suggest that OFC neural activity, in addition to encoding subjective values on a long timescale that is sensitive to satiety, also encodes a signal that fluctuates on a shorter timescale and thereby reflects some of the statistically improbable aspects of free-choice behavior.

BACKGROUND/OBJECTIVES The present study investigated Korean and Taiwan adults on the importance of and the satisfaction with street food sanitation and street food choice factor, in order to present management and improvement measures for street foods. SUBJECTS/METHODS The present study conducted a survey on 400 randomly chosen adults (200 Korean, 200 Taiwanese). General characteristics, eating habits, street food intake frequency, and preference by type of street food of respondents were checked. Respondents' importance and satisfaction of street food hygiene and selection attributes were also measured. In order to test for the difference between groups, χ2-test and t-test were performed. ISA was also performed to analyze importance and satisfaction. RESULTS Results showed that the importance of sanitation was significantly higher than satisfaction on all items in both Korea and Taiwan, and the satisfaction with sanitation was higher in Taiwan than in Korea. According to ISA results with street food sanitation, satisfaction was low while importance was high in both Korea and Taiwan. In terms of street food choice factor, importance scores were significantly higher than satisfaction scores on all items. In addition, satisfaction scores on all items except 'taste' were significantly higher in Taiwan than in Korea. CONCLUSIONS A manual on sanitation management of street foods should be developed to change the knowledge and attitude toward sanitation by putting into practice a regularly conducted education. Considering the popularity of street foods and its potential as a tourism resource to easily publicize our food culture, thorough management measures should be prepared on sanitation so that safe street food culture should be created.

2016-01-01

Background. Only 49% of infectious diseases (ID) fellowship programs were filled in 2015 through the national match, but little is known about internal medicine (IM) resident perceptions of ID and factors related to IM resident career choice. Methods. We conducted 25 interviews and disseminated a Web-based survey to graduating IM residents in the United States utilizing a 2-stage sampling strategy. Participants were categorized into 3 groups based on interest in ID: (1) applied/intended to apply to ID; (2) interested in ID but did not apply; (3) never interested in ID. We conducted all analysis using poststratification adjustment weights with survey data analysis procedures. Results. Of the 590 participants, 42 (7%) selected category 1, 188 (32%) category 2, and 360 (61%) category 3. Most (65%) developed an interest in their ultimate career before residency. Of those interested in ID, >52% rated their ID medical school curriculum as very good and influential on their interest in ID. Ninety-one percent of category 2 participants felt mentorship was influential on career choice, although 43% identified an ID mentor. Category 2 chose salary as the most dissuading factor and the most likely intervention to increase ID interest. Conclusions. In this nationally representative sample of graduating IM residents, most develop an interest in their ultimate career before residency. Factors influencing this decision reside in both medical school and residency, which is consistent with career decision-making constructs. By identifying career determining factors and understanding how they fit into medical training frameworks, we can develop targeted initiatives to reinvigorate interest in ID. PMID:27126345

Rapid regulation of brain-derived neurotrophic factor mRNA within eye-specific circuits during ocular dominance column formation.

PubMed

Lein, E S; Shatz, C J

2000-02-15

The neurotrophin brain-derived neurotrophic factor (BDNF) has emerged as a candidate retrograde signaling molecule for geniculocortical axons during the formation of ocular dominance columns. Here we examined whether neuronal activity can regulate BDNF mRNA in eye-specific circuits in the developing cat visual system. Dark-rearing throughout the critical period for ocular dominance column formation decreases levels of BDNF mRNA within primary visual cortex, whereas short-term (2 d) binocular blockade of retinal activity with tetrodotoxin (TTX) downregulates BDNF mRNA within the lateral geniculate nucleus (LGN) and visual cortical areas. Brief (6 hr to 2 d) monocular TTX blockade during the critical period and also in adulthood causes downregulation in appropriate eye-specific laminae in the LGN and ocular dominance columns within primary visual cortex. Monocular TTX blockade at postnatal day 23 also downregulates BDNF mRNA in a periodic fashion, consistent with recent observations that ocular dominance columns can be detected at these early ages by physiological methods. In contrast, 10 d monocular TTX during the critical period does not cause a lasting decrease in BDNF mRNA expression in columns pertaining to the treated eye, consistent with the nearly complete shift in physiological response properties of cortical neurons in favor of the unmanipulated eye known to result from long-term monocular deprivation. These observations demonstrate that BDNF mRNA levels can provide an accurate "molecular readout" of the activity levels of cortical neurons and are consistent with a highly local action of BDNF in strengthening and maintaining active synapses during ocular dominance column formation.

Russian consumers' motives for food choice.

Honkanen, Pirjo; Frewer, Lynn

2009-04-01

Knowledge about food choice motives which have potential to influence consumer consumption decisions is important when designing food and health policies, as well as marketing strategies. Russian consumers' food choice motives were studied in a survey (1081 respondents across four cities), with the purpose of identifying consumer segments based on these motives. These segments were then profiled using consumption, attitudinal and demographic variables. Face-to-face interviews were used to sample the data, which were analysed with two-step cluster analysis (SPSS). Three clusters emerged, representing 21.5%, 45.8% and 32.7% of the sample. The clusters were similar in terms of the order of motivations, but differed in motivational level. Sensory factors and availability were the most important motives for food choice in all three clusters, followed by price. This may reflect the turbulence which Russia has recently experienced politically and economically. Cluster profiles differed in relation to socio-demographic factors, consumption patterns and attitudes towards health and healthy food.

Determinants of choice of delivery place: Testing rational choice theory and habitus theory.

Broda, Anja; Krüger, Juliane; Schinke, Stephanie; Weber, Andreas

2018-05-07

The current study uses two antipodal social science theories, the rational choice theory and the habitus theory, and applies these to describe how women choose between intraclinical (i.e., hospital-run birth clinics) and extraclinical (i.e., midwife-led birth centres or home births) delivery places. Data were collected in a cross-sectional questionnaire-based survey among 189 women. A list of 22 determinants, conceptualized to capture the two theoretical concepts, were rated on a 7-point Likert scale with 1 = unimportant to 7 = very important. The analytic method was structural equation modelling. A model was built, in which the rational choice theory and the habitus theory as latent variables predicted the choice of delivery place. With regards to the choice of delivery place, 89.3% of the women wanted an intraclinical and 10.7% an extraclinical delivery place at the time of their last child's birth. Significant differences between women with a choice of an intraclinical or extraclinical delivery place were found for 14 of the 22 determinants. In the structural equation model, rational choice theory determinants predicted a choice of intraclinical delivery and habitus theory determinants predicted a choice of extraclinical delivery. The two theories had diametrically opposed effects on the choice of delivery place. Women are more likely to decide on intraclinical delivery when arguments such as high medical standards, positive evaluations, or good advanced information are rated important. In contrast, women are more likely to decide on extraclinical delivery when factors such as family atmosphere during birth, friendliness of health care professionals, or consideration of the woman's interests are deemed important. A practical implication of our study is that intraclinical deliveries may be promoted by providing comprehensive information, data and facts on various delivery-related issues, while extraclinical deliveries may be fostered by healthcare

Own-Choice Marriage and Fertility in Turkey

PubMed Central

Weinreb, Alexander A.

2016-01-01

Goode’s foundational work on the fertility transition identified own-choice marriage as a factor driving fertility decline, part of a widening repertoire of choice pertaining to marriage and childbearing. Yet research supporting this connection in today’s transitional societies is scarce and somewhat contradictory, and it is unclear how other marital traditions, such as consanguineous marriage, shape this relationship. This study evaluates Goode’s theorized connection using pooled Demographic and Health Survey data from Turkey, comparing children ever born, use of contraception, and parity progression across four types of marriage: own-choice and arranged marriage; and marriage to a cousin versus an unrelated spouse. Results are largely consistent with the idea that a move towards own-choice marriage reflects a widening repertoire of choice that also leads to fertility decline. However, they also show that hybrid models like own-choice marriage to a cousin tempers these effects. PMID:28316343

Long-acting reversible contraceptive (LARC) methods can prevent teen pregnancy yet remain underutilized by adolescents in the United States. Pediatric providers are well positioned to discuss LARCs with adolescents, but little is known about how counseling should occur in pediatric primary care settings. We explored adolescent womens' attitudes and experiences with LARCs to inform the development of adolescent-centered LARC counseling strategies. Qualitative analysis of one-on-one interviews. Participants were recruited from 2 urban school-based, primary care centers. Thirty adolescent women aged 14-18 years, diverse in race/ethnicity, and sexual experience. Interviews were audio-recorded, transcribed, and coded using inductive and deductive coding. Major themes were identified to integrate LARC-specific adolescent preferences into existing counseling approaches. Participants (mean age, 16.2 years; range, 14-18 years) represented a diverse range of racial and/or ethnic identities. Half (15/30) were sexually active and 17% (5/30) reported current or past LARC use. Five themes emerged regarding key factors that influence LARC choice, including: (1) strong preferences about device-specific characteristics; (2) previous exposure to information about LARCs from peers, family members, or health counseling sessions; (3) knowledge gaps about LARC methods that affect informed decision-making; (4) personal circumstances or experiences that motivate a desire for effective and/or long-acting contraception; and (5) environmental constraints and supports that might influence adolescent access to LARCs. We identified 5 factors that influence LARC choice among adolescent women and propose a framework for incorporating these factors into contraceptive counseling services in pediatric primary care settings.

Surgery is an emotionally, physically and mentally challenging profession, and medical students factor in many variables when choosing surgery as a career choice. The aim of this study is to review the available literature on the factors influencing Australian medical students' choice of surgery as their career. A search of EMBASE and MEDLINE with the search terms 'medical students' AND 'surgery'; 'medical students' AND 'career pathways'; 'medical students' AND 'career choices' was conducted. Additionally, Google Scholar and the reference list of some articles were canvassed for suitable areas of study. Lifestyle factors were the main reason influencing medical student's career choices. A balance between work, family and lifestyle was found to be important, and a surgical career choice was not always compatible with this. In particular, female students placed more importance on family and lifestyle factors when opting for non-surgical careers. Positive exposure and/or experiences in a surgical environment, perceived prestige and perceived financial reward were associated with surgical career choice. There is a need to better understand the factors influencing surgical and non-surgical career choice among Australian medical students, and develop appropriate interventions to promote surgery as a career. This article does not discuss personality traits of people who go into surgery. © 2013 Royal Australasian College of Surgeons.

Choice.

Understanding how and why analysands make the choices they do is central to both the clinical and the theoretical projects of psychoanalysis. And yet we know very little about the process of choice or about the relationship between choices and motives. A striking parallel is to be found between the ways choice is narrated in ancient Greek texts and the experience of analysts as they observe patients making choices in everyday clinical work. Pursuing this convergence of classical and contemporary sensibilities will illuminate crucial elements of the various meanings of choice, and of the way that these meanings change over the course of psychoanalytic treatment.

Choice of electricity provider in California after deregulation

NASA Astrophysics Data System (ADS)

Keanini, Rasa Ilze

Surveys often ask consumers how much they are willing to pay for certain goods and services, without requiring the consumer to actually pay for the good or service. Such surveys, termed stated preference studies, find that consumers value renewable electricity. This result is in contrast to actual experiences in recently deregulated electricity markets in several states, including California. When given the opportunity to choose in California, only one to two percent of the population opted for renewable electricity products. This dissertation used data from residential customers who chose an alternative electricity product in California's deregulated electricity market to determine the value placed on the renewable attribute of electricity products. This dissertation begins by taking a historical look at the electricity market of the nation and specifically California. From 1998 through 2001, California's electricity market was deregulated to include retail competition. This dissertation used data from electric service providers to reveal the factors influencing residential customer's choice of electricity product. Discrete choice models were used to determine the factors influencing electricity product choice. The results indicated that both price and renewable content had an effect on choice of product. Additionally, a more complicated model jointly estimating the discrete choice of electricity product with the continuous choice of electricity consumption (kWh) was specified and estimated.

The potential for health promotion through social networking sites (SNSs) is widely recognized. However, while health promotion prides itself in focusing on the social determinants of health, its partiality for persuading individuals to comply with health behaviours dominates the way health promotion utilizes SNSs. This paper contributes to an understanding of collaborative ways SNSs can work for health promotion agendas of self-determination and empowerment in an Indigenous Australia context. An ethnographic study was undertaken with Deadly Choices, an Indigenous-led health promotion initiative. The study involved participant observation of interactions on Deadly Choices SNSs between Deadly Choices and its online community members. Deadly Choices provides an example of SNSs providing a powerful tool to create a safe, inclusive and positive space for Indigenous people and communities to profile their healthy choices, according to Indigenous notions of health and identity. The study found five principles that underpin Deadly Choices' use of SNSs for health promotion. These are: create a dialogue; build community online and offline; incentivise healthy online engagement; celebrate Indigenous identity and culture; and prioritize partnerships. Deadly Choices SNSs empowers Indigenous people and communities to be health promoters themselves, which represents a power shift from health promotion practitioner to Indigenous people and communities and more broadly, an enactment of Indigenous self-determination on SNSs. Mainstream health promotion can learn from Indigenous health promotion practice regarding the use of SNSs for health promotion agendas. © The Author 2017. Published by Oxford University Press.

Theory of choice in bandit, information sampling and foraging tasks.

PubMed

Averbeck, Bruno B

2015-03-01

Decision making has been studied with a wide array of tasks. Here we examine the theoretical structure of bandit, information sampling and foraging tasks. These tasks move beyond tasks where the choice in the current trial does not affect future expected rewards. We have modeled these tasks using Markov decision processes (MDPs). MDPs provide a general framework for modeling tasks in which decisions affect the information on which future choices will be made. Under the assumption that agents are maximizing expected rewards, MDPs provide normative solutions. We find that all three classes of tasks pose choices among actions which trade-off immediate and future expected rewards. The tasks drive these trade-offs in unique ways, however. For bandit and information sampling tasks, increasing uncertainty or the time horizon shifts value to actions that pay-off in the future. Correspondingly, decreasing uncertainty increases the relative value of actions that pay-off immediately. For foraging tasks the time-horizon plays the dominant role, as choices do not affect future uncertainty in these tasks.

2007-12-01

Floors are a major element of newborn intensive care unit (NICU) construction. They provide visual cues, sound control, and with certain materials, some degree of physical comfort for workers. Flooring materials may entail a significant cost for installation and upkeep and can have substantial ecological impact, both in the choice of the flooring itself, as well as the substances used to clean it. In this article the important aspects to consider for each factor are explored and recommendations are offered for appropriate choices in various NICU areas.

This study aimed to determine the factors influencing patients' choice of physician at the first visit through database analysis of a tertiary hospital in South Korea. We collected data on the first treatments performed by physicians who had treated patients for at least 3 consecutive years over 10 years (from 2003 to 2012) from the database of Seoul National University's affiliated tertiary hospital. Ultimately, we obtained data on 524,012 first treatments of 319,004 patients performed by 115 physicians. Variables including physicians' age and medical school and patients' age were evaluated as influencing factors for the number of first treatments performed by each physician in each year using a Poisson regression through generalized estimating equations with a log link. The number of first treatments decreased over the study period. Notably, the relative risk for first treatments was lower among older physicians than among younger physicians (relative risk 0.96; 95% confidence interval 0.95 to 0.98). Physicians graduating from Seoul National University (SNU) also had a higher risk for performing first treatments than did those not from SNU (relative risk 1.58; 95% confidence interval 1.18 to 2.10). Finally, relative risk was also higher among older patients than among younger patients (relative risk 1.03; 95% confidence interval 1.01 to 1.04). This study systematically demonstrated that physicians' age, whether the physician graduated from the highest-quality university, and patients' age all related to patients' choice of physician at the first visit in a tertiary university hospital. These findings might be due to Korean cultural factors.

Dominant factor analysis of B-flow twinkling sign with phantom and simulation data.

Lu, Weijia; Haider, Bruno

2017-01-01

The twinkling sign in B-flow imaging (BFI-TS) has been reported in the literature to increase both specificity and sensitivity compared to the traditional gray-scale imaging. Unfortunately, there has been no conclusive study on the mechanism of this effect. In the study presented here, a comparative test on phantoms is introduced, where the variance of a phase estimator is used to quantify the motion amplitude. The statistical inference is employed later to find the dominate factor for the twinkling sign, which is proven by computer simulation. Through the analysis, it is confirmed that the tissue viscoelasticity is closely coupled with the twinkling sign. Moreover, the acoustic radiation force caused by tissue attenuation is found to be the trigger of the twinkling sign. Based on these findings, the BFI-TS is interpreted as a tissue movement triggering vibration of microcalcifications particle.

Factors Influencing Internal Medicine Resident Choice of Infectious Diseases or Other Specialties: A National Cross-sectional Study.

Only 49% of infectious diseases (ID) fellowship programs were filled in 2015 through the national match, but little is known about internal medicine (IM) resident perceptions of ID and factors related to IM resident career choice. We conducted 25 interviews and disseminated a Web-based survey to graduating IM residents in the United States utilizing a 2-stage sampling strategy. Participants were categorized into 3 groups based on interest in ID: (1) applied/intended to apply to ID; (2) interested in ID but did not apply; (3) never interested in ID. We conducted all analysis using poststratification adjustment weights with survey data analysis procedures. Of the 590 participants, 42 (7%) selected category 1, 188 (32%) category 2, and 360 (61%) category 3. Most (65%) developed an interest in their ultimate career before residency. Of those interested in ID, >52% rated their ID medical school curriculum as very good and influential on their interest in ID. Ninety-one percent of category 2 participants felt mentorship was influential on career choice, although 43% identified an ID mentor. Category 2 chose salary as the most dissuading factor and the most likely intervention to increase ID interest. In this nationally representative sample of graduating IM residents, most develop an interest in their ultimate career before residency. Factors influencing this decision reside in both medical school and residency, which is consistent with career decision-making constructs. By identifying career determining factors and understanding how they fit into medical training frameworks, we can develop targeted initiatives to reinvigorate interest in ID. © The Author 2016.

Mechanisms of Individual Differences in Impulsive and Risky Choice in Rats

PubMed Central

Kirkpatrick, Kimberly; Marshall, Andrew T.; Smith, Aaron P.

2016-01-01

Individual differences in impulsive and risky choice are key risk factors for a variety of maladaptive behaviors such as drug abuse, gambling, and obesity. In our rat model, ordered individual differences are stable across choice parameters, months of testing, and span a broad spectrum, suggesting that rats, like humans, exhibit trait-level impulsive and risky choice behaviors. In addition, impulsive and risky choices are highly correlated, suggesting a degree of correlation between these two traits. An examination of the underlying cognitive mechanisms has suggested an important role for timing processes in impulsive choice. In addition, in an examination of genetic factors in impulsive choice, the Lewis rat strain emerged as a possible animal model for studying disordered impulsive choice, with this strain demonstrating deficient delay processing. Early rearing environment also affected impulsive behaviors, with rearing in an enriched environment promoting adaptable and more self-controlled choices. The combined results with impulsive choice suggest an important role for timing and reward sensitivity in moderating impulsive behaviors. Relative reward valuation also affects risky choice, with manipulation of objective reward value (relative to an alternative reference point) resulting in loss chasing behaviors that predicted overall risky choice behaviors. The combined results are discussed in relation to domain-specific versus domain-general subjective reward valuation processes and the potential neural substrates of impulsive and risky choice.

Economic rationality and health and lifestyle choices for people with diabetes.

PubMed

Baker, Rachel Mairi

2006-11-01

Economic rationality is traditionally represented by goal-oriented, maximising behaviour, or 'instrumental rationality'. Such a consequentialist, instrumental model of choice is often implicit in a biomedical approach to health promotion and education. The research reported here assesses the relevance of a broader conceptual framework of rationality, which includes 'procedural' and 'expressive' rationality as complements to an instrumental model of rationality, in a health context. Q methodology was used to derive 'factors' underlying health and lifestyle choices, based on a factor analysis of the results of a card sorting procedure undertaken by 27 adult respondents with type 2 diabetes in Newcastle upon Tyne, UK. These factors were then compared with the rationality framework and the appropriateness of an extended model of economic rationality as a means of better understanding health and lifestyle choices was assessed. Taking a wider rational choice perspective, choices which are rendered irrational within a narrow-biomedical or strictly instrumental model, can be understood in terms of a coherent rationale, grounded in the accounts of respondents. The implications of these findings are discussed in terms of rational choice theory and diabetes management and research.

Free choice in residential care for older people - A philosophical reflection.

Free choice in elderly care services is a debated issue. Using the theoretical support of philosophers of free will, this paper explores free choice in relocation to residential care. The three dominant perspectives within this field of philosophy, libertarianism, determinism and compatibilism, are applied from the perspective of the older individual to the process of moving. Empirical data were collected through qualitative interviews with 13 older individuals who had recently moved into residential care. These individuals had made the choice to move following either a health emergency or incremental health problems. In a deterministic perspective they had no alternative to moving, which was the inevitable solution to their various personal problems. A network of people important to them assisted in the move, making the choice possible. However, post-move the interviewees' perspective had changed to a libertarian or compatibilist interpretation, whereby although the circumstances had conferred little freedom regarding the move. The interviewees reported a high degree of self-determination in the process. It appeared that in order to restore self-respect and personal agency, the older individuals had transformed their restricted choice into a choice made of free will or freer will.

In subcritical assemblies, the Bell and Glasstone spatial correction factor is used to correct the measured reactivity from different detector positions. In addition to the measuring position, several other parameters affect the correction factor: the detector material, the detector size, and the energy-angle distribution of source neutrons. The effective multiplication factor calculated by computer codes in criticality mode slightly differs from the average value obtained from the measurements in the different experimental channels of the subcritical assembly, which are corrected by the Bell and Glasstone spatial correction factor. Generally, this difference is due to (1) neutron counting errors; (2) geometrical imperfections, which are not simulated in the calculational model, and (3) quantities and distributions of material impurities, which are missing from the material definitions. This work examines these issues and it focuses on the detector choice and the calculation methodologies. The work investigated the YALINA Booster subcritical assembly of Belarus, which has been operated with three different fuel enrichments in the fast zone either: high (90%) and medium (36%), medium (36%), or low (21%) enriched uranium fuel.

Sad Facial Expressions Increase Choice Blindness

Previous studies have discovered a fascinating phenomenon known as choice blindness—individuals fail to detect mismatches between the face they choose and the face replaced by the experimenter. Although previous studies have reported a couple of factors that can modulate the magnitude of choice blindness, the potential effect of facial expression on choice blindness has not yet been explored. Using faces with sad and neutral expressions (Experiment 1) and faces with happy and neutral expressions (Experiment 2) in the classic choice blindness paradigm, the present study investigated the effects of facial expressions on choice blindness. The results showed that the detection rate was significantly lower on sad faces than neutral faces, whereas no significant difference was observed between happy faces and neutral faces. The exploratory analysis of verbal reports found that participants who reported less facial features for sad (as compared to neutral) expressions also tended to show a lower detection rate of sad (as compared to neutral) faces. These findings indicated that sad facial expressions increased choice blindness, which might have resulted from inhibition of further processing of the detailed facial features by the less attractive sad expressions (as compared to neutral expressions).

Postgraduate specialization is perceived as essential for success with high competition for enrolment. The reasons how medical students choose their postgraduate specialty are complex. Understanding the factors that influence career choice helps in workforce planning. So, we tried to identify the specialty preferred by postgraduate students and the factors that influenced these choices in a post graduate institution. A cross-sectional observational study was conducted in National Academy of Medical Sciences. All the postgraduate students of batch 2011 AD were enrolled for the study. The responses were rated on a five point Likert scale. Significant gender preference was observed in specialties. General Surgery, Internal Medicine and Orthopedics were chosen by male students (P-Values, respectively, 0.001, 0.033 and 0.000) while Obstetrics and Gynecology and Ophthalmology being chosen by female students (P-Values, respectively, 0.000 and 0.006). Significant difference was observed between male and female student responses to the factor - scope in future (P - value 0.042), between married and unmarried students to the factor - workload flexibility (P - value 0.011), students who tried to go abroad versus who didn't, for the factor - Illness of self/family/friend (P - value 0.016), and between those who worked in rural area versus those who didn't, to the factor - Influence of friends/ seniors (P - value 0.038). Various factors affect the choices for preferred specialty. Policy makers should look at the needs of the nation, and ensure that specialty postgraduate education programs reflect those needs.

Significant differences in physical and behavioural/emotional/cognitive predictors and attributes, as well as of neurochemical inducers of behaviour, between dominant and subordinate animals are discussed. It is still unknown whether these factors are the causes of differences between dominants and subordinates, or vice versa whether the differences between dominants and subordinates are the origin of differences in these factors. The possibility is discussed that no differences exist among juveniles in the concentrations of neurochemical agents (known in the literature as determinants of dominance) between the brains of future dominants and future subordinates. We describe a study design that makes the assessment of the 'original' neurochemical profile of the brain possible. © 2014 The Authors. Biological Reviews © 2014 Cambridge Philosophical Society.

Valence of emotions and moral decision-making: increased pleasantness to pleasant images and decreased unpleasantness to unpleasant images are associated with utilitarian choices in healthy adults

Moral decision-making is a key asset for humans’ integration in social contexts, and the way we decide about moral issues seems to be strongly influenced by emotions. For example, individuals with deficits in emotional processing tend to deliver more utilitarian choices (accepting an emotionally aversive action in favor of communitarian well-being). However, little is known about the association between emotional experience and moral-related patterns of choice. We investigated whether subjective reactivity to emotional stimuli, in terms of valence, arousal, and dominance, is associated with moral decision-making in 95 healthy adults. They answered to a set of moral and non-moral dilemmas and assessed emotional experience in valence, arousal and dominance dimensions in response to neutral, pleasant, unpleasant non-moral, and unpleasant moral pictures. Results showed significant correlations between less unpleasantness to negative stimuli, more pleasantness to positive stimuli and higher proportion of utilitarian choices. We also found a positive association between higher arousal ratings to negative moral laden pictures and more utilitarian choices. Low dominance was associated with greater perceived difficulty over moral judgment. These behavioral results are in fitting with the proposed role of emotional experience in moral choice.

2007-09-22

To obtain insight into the career choice of recently graduated physicians and the factors that influence this choice. Descriptive. Questionnaires were sent to 1091 physicians who graduated from the VU University in Amsterdam or the University Utrecht between 1 July 1999 and 30 June 2002. Graduates were asked to provide the following information: current occupation, number of days that they have worked in current occupation, 5-year career goals, prerequisites for obtaining a residency, time spent on patient care and research, and the extent to which certain factors have influenced their career choice. Respondents were subdivided into three groups: clinical specialists, general practitioners, and public or occupational health professionals. The response was 70%, and approximately half of the respondents were engaged in additional resident training: 68% in a clinical specialty, 23% in general practice, 9% in public or occupational health, and 2% in another occupation. Most of the respondents worked full-time but would prefer to work less in the future. Full-time availability was the most important prerequisite for a clinical residency. Work experience after graduation was also considered important to obtain a residency in general practice or public or occupational health. Among clinical and general practitioner residents, the most important factor influencing career choice was interest in the specific field. For public and occupational health residents, the most important factor was working within office hours, particularly for female respondents. Various factors influence career choice in recently graduated physicians, and these factors are specialty-dependent. Graduates are interested in the possibility of working part-time in their present occupation and in the near future.

Mathematical learning instruction and teacher motivation factors affecting science technology engineering and math (STEM) major choices in 4-year colleges and universities: Multilevel structural equation modeling

2011-12-01

Using the Educational Longitudinal Study of 2002/06, this study examined the effects of the selected mathematical learning and teacher motivation factors on graduates' science, technology, engineering, and math (STEM) related major choices in 4-year colleges and universities, as mediated by math performance and math self-efficacy. Using multilevel structural equation modeling, I analyzed: (1) the association between mathematical learning instruction factors (i.e., computer, individual, and lecture-based learning activities in mathematics) and students' STEM major choices in 4-year colleges and universities as mediated by math performance and math self-efficacy and (2) the association between school factor, teacher motivation and students' STEM major choices in 4-year colleges and universities via mediators of math performance and math self-efficacy. The results revealed that among the selected learning experience factors, computer-based learning activities in math classrooms yielded the most positive effects on math self-efficacy, which significantly predicted the increase in the proportion of students' STEM major choice as mediated by math self-efficacy. Further, when controlling for base-year math Item Response Theory (IRT) scores, a positive relationship between individual-based learning activities in math classrooms and the first follow-up math IRT scores emerged, which related to the high proportion of students' STEM major choices. The results also indicated that individual and lecture-based learning activities in math yielded positive effects on math self-efficacy, which related to STEM major choice. Concerning between-school levels, teacher motivation yielded positive effects on the first follow up math IRT score, when controlling for base year IRT score. The results from this study inform educators, parents, and policy makers on how mathematics instruction can improve student math performance and encourage more students to prepare for STEM careers.

Lin, Chia-Wei; Su, Fong-Chin; Wu, Hong-Wen; Lin, Cheng-Feng

2013-01-01

Turns (pirouettes) are an important movement in ballet and may be affected by "lateral bias". This study investigated physiological differences exhibited by experienced and novice dancers, respectively, when performing pirouette with dominant and non-dominant leg supports, respectively. Thirteen novice and 13 experienced dancers performed turns on dominant or non-dominant legs. The maximum ankle plantarflexion, knee extension and hip extension were measured during the single-leg support phase. The inclination angle of rotation axis is the angle between instantaneous rotation axis and global vertical axis in the early single-leg support phase. Both groups exhibited a greater hip extension, knee extension, and ankle plantarflexion when performing a turn on the non-dominant leg. For experienced dancers, the inclination angle of rotation axis during the pre-swing phase was generally smaller for dominant leg support than non-dominant leg. However, no significant difference was found in inclination angle of rotation axis of novice dancers. For experienced dancers, an improved performance is obtained when using the dominant leg for support. By contrast, for novice dancers, the performance is independent of choice of support leg. The significant lateral bias in experienced dancers indicates the possible influence of training. That is, repetitive rehearsal on the preferred leg strengthens the impact of side dominance in experienced dancers.

A national sample of PhD-trained scientists completed training, accepted subsequent employment in academic and nonacademic positions, and were queried about their previous graduate training and current employment. Respondents indicated factors contributing to their employment decision (e.g., working conditions, salary, job security). The data indicate the relative importance of deciding factors influencing career choice, controlling for gender, initial interest in faculty careers, and number of postgraduate publications. Among both well-represented (WR; n = 3444) and underrepresented minority (URM; n = 225) respondents, faculty career choice was positively associated with desire for autonomy and partner opportunity and negatively associated with desire for leadership opportunity. Differences between groups in reasons endorsed included: variety, prestige, salary, family influence, and faculty advisor influence. Furthermore, endorsement of faculty advisor or other mentor influence and family or peer influence were surprisingly rare across groups, suggesting that formal and informal support networks could provide a missed opportunity to provide support for trainees who want to stay in faculty career paths. Reasons requiring alteration of misperceptions (e.g., limited leadership opportunity for faculty) must be distinguished from reasons requiring removal of actual barriers. Further investigation into factors that affect PhDs' career decisions can help elucidate why URM candidates are disproportionately exiting the academy. © 2016 R. L. Layton et al.

Neuro-economics in chicks: foraging choices based on amount, delay and cost.

PubMed

Matsushima, Toshiya; Kawamori, Ai; Bem-Sojka, Tiaza

2008-06-15

Studies on the foraging choices are reviewed, with an emphasis on the neural representations of elementary factors of food (i.e., amount, delay and consumption time) in the avian brain. Domestic chicks serve as an ideal animal model in this respect, as they quickly associate cue colors with subsequently supplied food rewards, and their choices are quantitatively linked with the rewards. When a pair of such color cues was simultaneously presented, the trained chicks reliably made choices according to the profitability of food associated with each color. Two forebrain regions are involved in distinct aspects of choices; i.e., nucleus accumbens-medial striatum (Ac-MSt) and arcopallium intermedium (AI), an association area in the lateral forebrain. Localized lesions of Ac-MSt enhanced delay aversion, and the ablated chicks made impulsive choices of immediate reward more frequently than sham controls. On the other hand, lesions of AI enhanced consumption-time aversion, and the ablated chicks shifted their choices toward easily consumable reward with their impulsiveness unchanged; delay and consumption time are thus doubly dissociated. Furthermore, chicks showed distinct patterns of risk-sensitive choices depending on the factor that varied at trials. Risk aversion occurred when food amount varied, whereas consistent risk sensitivity was not found when the delay varied; amount and delay were not interchangeable. Choices are thus deviated from those predicted as optima. Instead, factors such as amount, delay and consumption time could be separately represented and processed to yield economically sub-optimal choices.

Factors Affecting Plan Choice and Unmet Need among Supplemental Security Income Eligible Children with Disabilities

Objective To evaluate factors affecting plan choice (partially capitated managed care [MC] option versus the fee-for-service [FFS] system) and unmet needs for health care services among children who qualified for supplemental security income (SSI) because of a disability. Data Sources We conducted telephone interviews during the summer and fall of 2002 with a random sample of close to 1,088 caregivers of SSI eligible children who resided in the District of Columbia. Research Design We employed a two-step procedure where we first estimated plan choice and then constructed a selectivity correction to control for the potential selection bias associated with plan choice. We included the selectivity correction, the dummy variable indicating plan choice and other exogenous regressors in the second stage equations predicting unmet need. The dependent variables in the second stage equations include: (1) having an unmet need for any service or equipment; (2) having an unmet need for physician or hospital services; (3) having an unmet need for medical equipment; (4) having an unmet need for prescription drugs; (5) having an unmet need for dental care. Principal Findings More disabled children (those with birth defects, chronic conditions, and/or more limitations in activities of daily living) were more likely to enroll in FFS. Children of caregivers with some college education were more likely to opt for FFS, whereas children from higher income households were more prone to enroll in the partially capitated MC plan. Children in FFS were 9.9 percentage points more likely than children enrolled in partially capitated MC to experience an unmet need for any type of health care services (p<.01), while FFS children were 4.5 percentage points more likely than partially capitated MC enrollees to incur a medical equipment unmet need (p<.05). FFS children were also more likely than partially capitated MC enrollees to experience unmet needs for prescription drugs and dental care

Individuals undertaking a weight loss effort have a choice among proven dietary approaches. Factors contributing to choice of either a low-fat/low-calorie diet or a low-carbohydrate diet, two of the most studied and popular dietary approaches, are unknown. The current study used data from participants randomized to the ‘choice’ arm of a trial examining whether being able to choose a diet regimen yields higher weight loss than being randomly assigned to a diet. At study entry, participants attended a group session during which they were provided tailored feedback indicating which diet was most consistent with their food preferences using the Geiselman Food Preference Questionnaire (FPQ), information about both diets, and example meals for each diet. One week later, they indicated which diet they chose to follow during the 48-week study, with the option of switching diets after 12 weeks. Of 105 choice arm participants, 44 (42%) chose the low-fat/low-calorie diet and 61 (58%) chose the low-carbohydrate diet. In bivariate analyses, diet choice was not associated with age, race, sex, education, BMI, or diabetes (all p > 0.05). Low-carbohydrate diet choice was associated with baseline higher percent fat intake (p = 0.007), lower percent carbohydrate intake (p = 0.02), and food preferences consistent with a low-carbohydrate diet according to FPQ (p < 0.0001). In a multivariable logistic regression model, only FPQ diet preference was associated with diet choice (p = 0.001). Reported reasons for diet choice were generally similar for those choosing either diet; however, concerns about negative health effects of the unselected diet was rated as more influential among participants selecting the low-fat diet. Only three low-carbohydrate and two low-fat diet participants switched diets at 12 weeks. Results suggest that when provided a choice between two popular weight loss dietary approaches, an individual's selection is likely influenced by baseline dietary intake pattern

Neural control of behavioural choice in juvenile crayfish.

PubMed

Liden, William H; Phillips, Mary L; Herberholz, Jens

2010-11-22

Natural selection leads to behavioural choices that increase the animal's fitness. The neuronal mechanisms underlying behavioural choice are still elusive and empirical evidence connecting neural circuit activation to adaptive behavioural output is sparse. We exposed foraging juvenile crayfish to approaching shadows of different velocities and found that slow-moving shadows predominantly activated a pair of giant interneurons, which mediate tail-flips that thrust the animals backwards and away from the approaching threat. Tail-flips also moved the animals farther away from an expected food source, and crayfish defaulted to freezing behaviour when faced with fast-approaching shadows. Under these conditions, tail-flipping, an ineffective and costly escape strategy was suppressed in favour of freezing, a more beneficial choice. The decision to freeze also dominated in the presence of a more desirable resource; however, the increased incentive was less effective in suppressing tail-flipping when paired with slow-moving visual stimuli that reliably evoked tail-flips in most animals. Together this suggests that crayfish make value-based decisions by weighing the costs and benefits of different behavioural options, and they select adaptive behavioural output based on the activation patterns of identifiable neural circuits.

The worldwide incidence of kidney failure is on the rise and treatment is costly; thus, the global burden of illness is growing. Kidney failure patients require either a kidney transplant or dialysis to maintain life. This review focuses on the economics of dialysis. Alternative dialysis modalities are haemodialysis (HD) and peritoneal dialysis (PD). Important economic factors influencing dialysis modality selection include financing, reimbursement and resource availability. In general, where there is little or no facility or physician reimbursement or payment for PD, the share of PD is very low. Regarding resource availability, when centre HD capacity is high, there is an incentive to use that capacity rather than place patients on home dialysis. In certain countries, there is interest in revising the reimbursement structure to favour home-based therapies, including PD and home HD. Modality selection is influenced by employment status, with an association between being employed and PD as the modality choice. Cost drivers differ for PD and HD. PD is driven mainly by variable costs such as solutions and tubing, while HD is driven mainly by fixed costs of facility space and staff. Many cost comparisons of dialysis modalities have been conducted. A key factor to consider in reviewing cost comparisons is the perspective of the analysis because different costs are relevant for different perspectives. In developed countries, HD is generally more expensive than PD to the payer. Additional research is needed in the developing world before conclusive statements may be made regarding the relative costs of HD and PD. PMID:18234844

This study focuses on the implementation of the food choice questionnaire (FCQ) across four countries. The first objective is to examine the degree to which the factor structure of the FCQ is invariant across different populations. The second objective is to analyse the motives for food choice in different countries. The cross-sectional sample of 1420 consumers consisted of Belgians (N=458), Hungarians (N=401), Romanians (N=229) and Filipinos (N=332). Data analyses included estimation of five multi-group confirmatory factor analysis models; calculation of mean importance ratings for each food choice factor across countries; ANOVA and Tukey post hoc tests; and a rank order test of most to least important factors within each country. The results confirm that the factorial structure of the FCQ is invariant with respect to factor configuration, factor loadings and item intercept. Sensory appeal is the most important factor among all European consumers, while health, convenience and price were all among the five most important factors shaping food choice in Belgium, Hungary and Romania. For Filipinos, the most important were health, price and mood. Sensory appeal ranked on the fourth place. Copyright © 2011 Elsevier Ltd. All rights reserved.

Utility of color Doppler indices of dominant follicular blood flow for prediction of clinical factors in in vitro fertilization-embryo transfer cycles.

2002-12-01

To investigate the relationship between color Doppler indices of dominant follicular blood flow and clinical factors in in vitro fertilization-embryo transfer cycles. This was a prospective study involving 26 patients completing a total of 33 in vitro fertilization cycles. Dominant follicular blood flow indices, peak systolic velocities, the resistance index and the pulsatility index were evaluated using transvaginal color Doppler. The indices were compared to the clinical outcomes of in vitro fertilization-embryo transfer. There was a significant correlation between dominant follicular peak systolic velocities and the number of oocytes retrieved, as well as the number of mature oocytes obtained. There was no significant correlation between dominant follicular resistance index or pulsatility index and the number of follicles > 10 mm in diameter, the number of oocytes retrieved or the number of mature oocytes. There were no significant differences between dominant follicular peak systolic velocities, resistance index or pulsatility index, and fertilization rate or the ratio of good quality embryos. However, significant differences were found between the number of oocytes retrieved, as well as the number of mature oocytes for those patients in which the peak systolic velocity was below 25 cm/s. Doppler assessment of dominant follicle blood flow alone is useful for predicting the number of retrievable oocytes. However, morphological quality of the embryo produced or the pregnancy rate cannot be predicted by this method.

The central aim of this article is to investigate mode choice behavior among commuters in Ho Chi Minh City using disaggregate mode choice model and norm activation theory. A better understanding of commuters’ choice of transport mode provide an opportunity to obtain valuable information on their travel behaviors which help to build a basic for proffering solutions stimulating commuters to switch to public transport, which in turn contribute to deal with traffic problems and environmental issues. Binary logistic regression was employed under disaggregate choice method. Key findings indicated that Demographic factors including Age (-0.308), Married (-9.089), Weather (-8.272); Trip factors including Travel cost (0.437), Travel distance (0.252), and Norm activation theory (Awareness of consequences: AC2 (-1.699), AC4 (2.951), AC6 (-3.523), AC7 (-2.092), AC9 (-3.045), AC11 (+ 2.939), and Personal norms: PN2 (-2.695)) had strong impact on the commuters’ mode choice. Although motorcycle was the major transport mode among commuters, they presented their willingness to switch to bus transport if it had less negative impacts on the environment and their daily living environment.

Dominance relationships among siamang males living in multimale groups.

PubMed

Morino, Luca

2016-03-01

Intense intolerance among males is considered to be an important mechanism maintaining the uni-male organization traditionally attributed to socially monogamous gibbons. Long-term field work, however, has revealed the existence of stable, socially polyandrous groups in at least two populations, raising questions about the mechanism that allows two adult males to co-reside in the same group. I collected 21 months of behavioral data on 7 two-male groups of wild siamangs (Symphalangus syndactylus) in southern Sumatra (Indonesia) to test the hypothesis that dominance relationships regulate the interactions of adult male siamangs and ultimately facilitate multi-male social groups. A dominant male could clearly be identified in each dyad, based on a consistent direction of agonistic interactions, displacements and the maintenance of an advantageous position in the canopy. Males identified as dominant enjoyed greater social access to the resident female and monopolized copulations. These results suggest that gibbons possess the psycho-social flexibility to regulate intra-sexual aggression and live in multi-male social units under certain social conditions. I discuss the effects that relatedness between males and female choice have in determining this grouping pattern, and the role of male intolerance in the maintenance of primate mating systems. © 2015 Wiley Periodicals, Inc.

Preferred modes of travel among older adults: what factors affect the choice to walk instead of drive?

There are many factors that influence older adults' travel choices. This paper explores the associations between mode of travel choice for a short trip and older adults' personal characteristics. This study included 406 drivers over the age of 64 who were enrolled in a large integrated health plan in the United States between 1991 and 2001. Bivariate analyses and generalized linear modeling were used to examine associations between choosing to walk or drive and respondents' self-reported general health, physical and functional abilities, and confidence in walking and driving. Having more confidence in their ability to walk versus drive increased an older adult's likelihood of walking to make a short trip by about 20% (PR=1.22; 95% CI: 1.06-1.40), and walking for exercise increased the likelihood by about 50% (PR=1.53; 95% CI=1.22-1.91). Reporting fair or poor health decreased the likelihood of walking, as did cutting down on the amount of driving due to a physical problem. Factors affecting a person's decision to walk for exercise may not be the same as those that influence their decision to walk as a mode of travel. It is important to understand the barriers to walking for exercise and walking for travel to develop strategies to help older adults meet both their exercise and mobility needs. Increasing walking over driving among older adults may require programs that increase confidence in walking and encourage walking for exercise.

Despite the high prevalence of mental disorders, a worldwide shortage of psychiatrists exists. Moreover, the number of students interested in choosing psychiatry as their future profession is low and psychiatry is frequently regarded as one of the least wanted medical specializations. We report the findings of a cross-sectional quantitative survey of final year Croatian medical students as part of the International Survey of Student Career Choice in Psychiatry (ISoSCCiP). The questionnaire consisted of three sections: socio-demographic factors, psychiatric education during medical school, and attitudes and personality characteristics. Out of 200 students, 122 completed the questionnaire (response rate 61%). The overall student evaluation of the compulsory psychiatry curriculum was 'average'. Significantly higher ratings were reported by students who attended special psychiatry teaching modules, or felt more involved in the teaching of the subject. Poor evaluation of medical school psychiatric education significantly increased the likelihood of not choosing psychiatry as a future career. The choice of psychiatry was also predicted by attitudes towards psychiatry and by personal characteristics. In conclusion, student ratings of medical school psychiatric education and involvement in teaching appear to influence choice towards psychiatry. Addressing these issues may increase the number of students motivated to pursue psychiatry as their future career choice.

An investigation of factors affecting elementary female student teachers' choice of science as a major at college level in Zimbabwe

NASA Astrophysics Data System (ADS)

Mlenga, Francis Howard

The purpose of the study was to determine factors affecting elementary female student teachers' choice of science as a major at college level in Zimbabwe. The study was conducted at one of the Primary School Teachers' Colleges in Zimbabwe. A sample of two hundred and thirty-eight female student teachers was used in the study. Of these one hundred and forty-two were non-science majors who had been randomly selected, forty-one were science majors and forty-five were math majors. Both science and math majors were a convenient sample because the total enrollment of the two groups was small. All the subjects completed a survey questionnaire that had sixty-eight items. Ten students from the non-science majors were selected for individual interviews and the same was done for the science majors. A further eighteen were selected from the non-science majors and divided into three groups of six each for focus group interviews. The same was done for the science majors. The interviews were audio taped and transcribed. Data from the survey questionnaires were analyzed using Binary Logistic Regression which predicted factors that affected students' choice of science as a major. The transcribed interview data were analyzed used using domain, taxonomic and componential analyses. Results of the study indicated that elementary female students' choice of science as a major at college level is affected by students' attitudes toward science, teacher behavior, out-of-school experiences, role models, gender stereotyping, parental influence, peer influence, in-school experiences, and societal expectations, namely cultural and social expectations.

Background Several factors, which are components of pharmaceutical care, can influence a patient’s choice of a community pharmacy store and contribute to frequent visits to the same pharmacy. Objectives To compare factors that influence a patient’s choice of pharmacy in Poland and in the UK, to identify which of them are components of pharmaceutical care, and to relate them to patient loyalty to the same pharmacy. Methods A self-administered, anonymous questionnaire was distributed to clients visiting pharmacies in Poland and the UK January–August 2011. Comparisons were performed using chi-square tests and logistic regression. All statistical analyses were performed using SPSS 20.0. Results The response rate was 55.6% (n=417/750; 36 pharmacies) and 54.0% (n=405/750; 56 pharmacies) in Poland and in the UK, respectively. The most frequently reported factors, as defined by a percentage of responders, were in Poland: 1) location (84%); 2) professional and high-quality of service (82%); 3) good price of medicines (78%); and 4) promotions on medicines (66%). In the UK, the most commonly reported factors were: 1) professional and high quality of service (90%); 2) location (89%); 3) good advice received from the pharmacist (86%); and 4) option of discussing and consulting all health issues in a consultation room (80%). Good advice and an option of discussing personal concerns with a pharmacist are components of pharmaceutical care. Thirty-eight percent of patients in Poland and 61% in the UK declared visiting the same pharmacy. Conclusion Components of pharmaceutical care are important factors influencing the patient’s choice of pharmacy in the UK and, to a lesser degree, in Poland. Additionally, more patients in the UK than in Poland are committed to a single pharmacy. Therefore, implementing the full pharmaceutical care in Poland may contribute to an increase in patient loyalty and thus strengthen competitiveness of pharmacy businesses. PMID:24868150

Mate-choice copying, social information processing, and the roles of oxytocin.

PubMed

Kavaliers, Martin; Matta, Richard; Choleris, Elena

2017-01-01

Social and sexual behaviors, including that of mate choice, are dependent on social information. Mate choice can be modified by prior and ongoing social factors and experience. The mate choice decisions of one individual can be influenced by either the actual or potential mate choice of another female or male. Such non-independent mate choice, where individuals gain social information and socially learn about and recognizes potential mates by observing the choices of another female or male, has been termed "mate-choice copying". Here we first briefly review how, why, and under what circumstances individuals engage in mate-choice copying. Secondly, we review the neurobiological mechanisms underlying mate-choice copying. In particular, we consider the roles of the nonapeptide, oxytocin, in the processing of social information and the expression of mate-choice copying. Copyright © 2016 Elsevier Ltd.

Juvenile recurrent parotitis is a common cause of inflammatory salivary gland swelling in children. A variety of aetiological factors has been proposed for the condition. Here we present a family where four members had juvenile recurrent parotitis and where two other family members may have had an atypical form of the condition. The segregation pattern in the family is consistent with autosomal dominant inheritance with incomplete penetrance and this suggests that, at least in some cases, genetic factors may be implicated in juvenile recurrent parotitis.

OBJECTIVES Many factors influence the career specialty decisions made by medical students. The aim of this study was to broaden consideration of the determinants of specialty choice in a large population of medical students in their sixth year of study. METHODS A total of 2588 students distributed across all of the 39 medical schools in France participated in a National Practice Examination in December 2008, after which an electronic questionnaire was administered. Study criteria were: population characteristics; demographics, and motivation for and drawbacks to medical specialty choice. RESULTS A total of 1780 students (1111 women, 62%) responded to the questionnaire (69% response rate). The mean age of respondents was 23.8 years (22-35 years). Of these, 1555 students (87%) stated their preferred medical specialty. Surgical and medical specialties were the two specialties selected most frequently by students (n = 729, 47%). General practice was chosen by 20%. Gender influenced the choice of specialty: 88% of future paediatricians, 82% of gynaecologists and 77% of general practitioners (GPs) were women (p < 0.05). Main motivating factors included interesting diseases, opportunities for private practice and patient contact. Main drawbacks limiting the choice of other specialties were poor quality of life, an exclusively hospital-based career and loss of patient contact. Gender was the criterion most associated with significant differences in factors of motivation for or discouragement from a career. Patient contact and opportunities for private practice were significantly highlighted by future GPs compared with students opting for the medical or surgical specialties (p < 0.0001). CONCLUSIONS Students' career choices regarding specialties or general practice result from the interplay among several factors. Career interest in general practice is particularly low. Initiatives to address the factors affecting student career choices regarding less favoured specialties

Economic rationality in choosing between short-term bad-health choices and longer-term good-health choices.

PubMed

Campbell, David

2013-11-08

Non-contagious, chronic disease has been identified as a global health risk. Poor lifestyle choices, such as smoking, alcohol, drug and solvent abuse, physical inactivity, and unhealthy diet have been identified as important factors affecting the increasing incidence of chronic disease. The following focuses on the circumstance affecting the lifestyle or behavioral choices of Aboriginal and Torres Strait Islander peoples in remote-/very remote Australia. Poor behavioral choices are the result of endogenous characteristics that are influenced by a range of stressful exogenous variables making up the psychosocial determinants including social disenfranchisement, cultural loss, insurmountable tasks, the loss of volitional control and resource constraints. It is shown that poor behavioral choices can be economically rational; especially under highly stressful conditions. Stressful circumstances erode individual capacity to commit to long-term positive health alternatives such as self-investment in education. Policies directed at removing the impediments and providing incentives to behaviors involving better health choices can lead to reductions in smoking and alcohol consumption and improved health outcomes. Multijurisdictional culturally acceptable policies directed at distal variables relating to the psychosocial determinants of health and personal mastery and control can be cost effective. While the content of this paper is focused on the conditions of colonized peoples, it has broader relevance.

Background There is little data on the preferences of pharmacy students as regards their future pharmacy job choices in Africa and this has created concerns amongst licensing bodies, employers and also the institutions they graduate from. Objective Career choices and factors that influence these choices of pre-registration pharmacists were assessed. Methods Final and fourth year students from three schools of pharmacy were approached with a previously validated and employed questionnaire comprising questions on future job choices and reasons for that job choice. Data collected were subjected to descriptive and inferential analysis. Results Four hundred and eighty eight students took part in the study (response rate 71.5%). Majority (78.8%) was younger than 26 years and had a work experience (68.2%). Job flexibility was significantly more important to females, while younger students considered salary most important (p<0.05). Hospital and community practice were most preferred career choices. Other demographic factors (especially gender, marital status, previous degree and previous work experience) significantly affected career choices. Conclusions Age, gender, and previous work experience affect career choices of graduating pharmacy students. Patient-oriented practices (e.g. hospital and community) remain the most preferred careers. PMID:24223080

It is important for cancer patients to receive end-of-life care at the desired place. To identify issues in selection of place for end-of-life care of cancer patients to realize their optimal survivorship. Between September 2015 and January 2016, a questionnaire consisting of 33 items, including end-of-life care place preferences, was administered to cancer patients who attended three university hospitals in Japan. A total of 971 questionnaires were collected (response rate, 88.4%). Fifty-eight percent of patients preferred to stay at home to receive end-of-life care. In contrast, more than 80% of patients did not know the details of healthcare services. The factors significantly associated with patients' choice for place of end-of-life care at home were "male gender" (odds ratio [OR] = 1.43, p = 0.030), "living in a one-person household" (OR = 0.21, p < 0.001), "feeling close to friends" (OR = 0.94, p = 0.049), "thinking that the family is burdened" (OR = 0.55, p < 0.001), "thinking that pain is controllable at home" (OR = 1.39, p < 0.001), and "thinking that society should establish a system of home palliative care" (OR = 1.93, p < 0.001). This study identified six factors influencing the selection of a place for end-of-life care. Most patients have a desire for a social system that allows end-of-life care at home where they can live with their family, but have anxiety about treatment to deal with symptom change, with concern about burden on their family. These issues should be addressed in the future.

Does health affect portfolio choice?

PubMed

Love, David A; Smith, Paul A

2010-12-01

A number of recent studies find that poor health is empirically associated with a safer portfolio allocation. It is difficult to say, however, whether this relationship is truly causal. Both health status and portfolio choice are influenced by unobserved characteristics such as risk attitudes, impatience, information, and motivation, and these unobserved factors, if not adequately controlled for, can induce significant bias in the estimates of asset demand equations. Using the 1992-2006 waves of the Health and Retirement Study, we investigate how much of the connection between health and portfolio choice is causal and how much is due to the effects of unobserved heterogeneity. Accounting for unobserved heterogeneity with fixed effects and correlated random effects models, we find that health does not appear to significantly affect portfolio choice among single households. For married households, we find a small effect (about 2-3 percentage points) from being in the lowest of five self-reported health categories. Copyright © 2009 John Wiley & Sons, Ltd.

2017-01-01

We study choice over prescription insurance plans by the elderly using government administrative data to evaluate how these choices evolve over time. We find large “foregone savings” from not choosing the lowest cost plan that has grown over time. We develop a structural framework to decompose the changes in “foregone welfare” from inconsistent choices into choice set changes and choice function changes from a fixed choice set. We find that foregone welfare increases over time due primarily to changes in plan characteristics such as premiums and out-of-pocket costs; we estimate little learning at either the individual or cohort level.

Motives underlying food choice: dentists, porters and dietary health promotion.

PubMed

Crossley, M L; Khan, S N

2001-08-25

Differences in dental decay and disease amongst socioeconomic groups are thought to derive, in part, from variations in dietary practices and differences in education. The aim of this exploratory study was to examine whether differences in motivating factors affecting food choice could be found in a comparison of two groups at very different ends of the social spectrum: dentists and porters/cleaners. A convenience sample of 100 people (51 porters/cleaners and 49 dentists) working in the dental school at a university in the North West of England were approached to interview face-to-face and complete the Food Choice Questionnaire (FCQ), a previously validated measure designed to assess nine main factors relevant to peoples' food choices. A sample size of 100 was chosen because it was adequate to test validity (using a two-group Chi-square test with a 0.050 two sided significance). Findings were analysed using independent sample t-test and multiple linear regression. Results indicated significant differences between porters/cleaners and dentists in terms of their motives for food choice on six of the nine FCQ factors. These included convenience (p < 0.001), natural content (p < 0.05), price (p < 0.005), familiarity (p < .0001), mood (p < 0.03) and ethical concern (p < 0.01). Porters/cleaners tended to rate the factors covenience, price, mood and familiarity more highly, whereas dentists did the same for natural content and ethical concern. Awareness of the differences in motivational factors affecting food choice between different social groups is important to dental practitioners who are being taught to play an increasing role in health promotion. If dental practitioners are to partake meaningfully in such a role, it is necessary for them to be aware not only of their own motives in food selection, but also of the way in which those motives may differ from those of their clients.

Influencers of career choice among allied health students.

PubMed

Brown-West, A P

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.

Patient choice of a hospital: implications for health policy and management.

PubMed

Mosadeghrad, Ali Mohammad

2014-01-01

The purpose of this study was to identify the most important influencing factors in choosing a hospital by a patient. This study involved a mixed research design. Focus groups and in-depth individual interviews were conducted with patients to explore reasons for choosing a hospital. In addition, this study involved survey-based research on the patient choice. Type of the hospital, type of the service, word of mouth, cost of services, the health insurance programme, location, physical environment, facilities, providers' expertise and interpersonal behaviour, and reputation of the hospital influenced patients' choice of a hospital. Doctor recommendations and health insurance programme were the main reasons for choosing a hospital for inpatients and outpatients respectively. Identifying and understanding key factors that influence a patient choice of a healthcare setting helps managers and policy makers invest their resources in those critical areas and improve those aspects of their services to attract more patients. This article contributes to healthcare theory and practice by developing a conceptual framework for understanding the factors that influence a patient choice of a healthcare setting.

We report a study of referential choice in discourse production, understood as the choice between various types of referential devices, such as pronouns and full noun phrases. Our goal is to predict referential choice, and to explore to what extent such prediction is possible. Our approach to referential choice includes a cognitively informed theoretical component, corpus analysis, machine learning methods and experimentation with human participants. Machine learning algorithms make use of 25 factors, including referent’s properties (such as animacy and protagonism), the distance between a referential expression and its antecedent, the antecedent’s syntactic role, and so on. Having found the predictions of our algorithm to coincide with the original almost 90% of the time, we hypothesized that fully accurate prediction is not possible because, in many situations, more than one referential option is available. This hypothesis was supported by an experimental study, in which participants answered questions about either the original text in the corpus, or about a text modified in accordance with the algorithm’s prediction. Proportions of correct answers to these questions, as well as participants’ rating of the questions’ difficulty, suggested that divergences between the algorithm’s prediction and the original referential device in the corpus occur overwhelmingly in situations where the referential choice is not categorical.

Value-based choice: An integrative, neuroscience-informed model of health goals.

PubMed

Berkman, Elliot T

2018-01-01

Traditional models of health behaviour focus on the roles of cognitive, personality and social-cognitive constructs (e.g. executive function, grit, self-efficacy), and give less attention to the process by which these constructs interact in the moment that a health-relevant choice is made. Health psychology needs a process-focused account of how various factors are integrated to produce the decisions that determine health behaviour. I present an integrative value-based choice model of health behaviour, which characterises the mechanism by which a variety of factors come together to determine behaviour. This model imports knowledge from research on behavioural economics and neuroscience about how choices are made to the study of health behaviour, and uses that knowledge to generate novel predictions about how to change health behaviour. I describe anomalies in value-based choice that can be exploited for health promotion, and review neuroimaging evidence about the involvement of midline dopamine structures in tracking and integrating value-related information during choice. I highlight how this knowledge can bring insights to health psychology using illustrative case of healthy eating. Value-based choice is a viable model for health behaviour and opens new avenues for mechanism-focused intervention.

An imbalance of physician supply by medical specialty has been observed in most countries. In Korea, there is a greater tendency to avoid surgical specialties and specialty choices in nonclinical medicine, such as the basic science of medicine. In this study, we identified factors affecting the specialty choice of physicians in order to provide a basis for policies to address this problem. We used the results of a 2013 nationwide survey of 12 709 medical students (82.7 % responded) to analyze the data of 9499 students after excluding missing data. Descriptive analyses of all students' specialty choice were performed. Logistic regression was performed by selecting gender, age, grade level, type of medical school, hometown, and the location of the medical school as the independent variables. Medical specialty was the dependent variable. The dependent variable, or specialty of medicine, was categorized into three groups: nonclinical/clinical medicine, surgical-medical specialty, and controllable lifestyle specialty. The order of preferred medical specialties was internal medicine, psychiatry, and pediatrics; for surgical specialties, the order was orthopedic surgery, general surgery, and ophthalmology. Medical specialties were most favored by women and students in the third (men) and second (women) year of the medical program, whereas surgical specialties were most preferred by men and students in the first year of the program. Students in the third year mostly favored nonclinical medicine. Medical college students had a stronger preference for nonclinical medicine (odds ratio [OR] 1.625, 95 % confidence interval [CI] 1.139-2.318) than graduate medical school students. Surgical specialties were more favored by men (OR 2.537, 95 % CI 2.296-2.804) than by women. However, they were favored less by medical college students (OR 0.885, 95 % CI 0.790-0.991) than by graduate medical school students and by medical students in metropolitan areas (OR 0.892, 95 % CI 0

Adaptive History Biases Result from Confidence-Weighted Accumulation of past Choices

PubMed Central

2018-01-01

Perceptual decision-making is biased by previous events, including the history of preceding choices: observers tend to repeat (or alternate) their judgments of the sensory environment more often than expected by chance. Computational models postulate that these so-called choice history biases result from the accumulation of internal decision signals across trials. Here, we provide psychophysical evidence for such a mechanism and its adaptive utility. Male and female human observers performed different variants of a challenging visual motion discrimination task near psychophysical threshold. In a first experiment, we decoupled categorical perceptual choices and motor responses on a trial-by-trial basis. Choice history bias was explained by previous perceptual choices, not motor responses, highlighting the importance of internal decision signals in action-independent formats. In a second experiment, observers performed the task in stimulus environments containing different levels of autocorrelation and providing no external feedback about choice correctness. Despite performing under overall high levels of uncertainty, observers adjusted both the strength and the sign of their choice history biases to these environments. When stimulus sequences were dominated by either repetitions or alternations, the individual degree of this adjustment of history bias was about as good a predictor of individual performance as individual perceptual sensitivity. The history bias adjustment scaled with two proxies for observers' confidence about their previous choices (accuracy and reaction time). Together, our results are consistent with the idea that action-independent, confidence-modulated decision variables are accumulated across choices in a flexible manner that depends on decision-makers' model of their environment. SIGNIFICANCE STATEMENT Decisions based on sensory input are often influenced by the history of one's preceding choices, manifesting as a bias to systematically repeat

Air Cargo Transportation Route Choice Analysis

Obashi, Hiroshi; Kim, Tae-Seung; Oum, Tae Hoon

2003-01-01

Using a unique feature of air cargo transshipment data in the Northeast Asian region, this paper identifies the critical factors that determine the transshipment route choice. Taking advantage of the variations in the transport characteristics in each origin-destination airports pair, the paper uses a discrete choice model to describe the transshipping route choice decision made by an agent (i.e., freight forwarder, consolidator, and large shipper). The analysis incorporates two major factors, monetary cost (such as line-haul cost and landing fee) and time cost (i.e., aircraft turnaround time, including loading and unloading time, custom clearance time, and expected scheduled delay), along with other controls. The estimation method considers the presence of unobserved attributes, and corrects for resulting endogeneity by use of appropriate instrumental variables. Estimation results find that transshipment volumes are more sensitive to time cost, and that the reduction in aircraft turnaround time by 1 hour would be worth the increase in airport charges by more than $1000. Simulation exercises measures the impacts of alternative policy scenarios for a Korean airport, which has recently declared their intention to be a future regional hub in the Northeast Asian region. The results suggest that reducing aircraft turnaround time at the airport be an effective strategy, rather than subsidizing to reduce airport charges.

Motor (but not auditory) attention affects syntactic choice.

2018-01-01

Understanding the determinants of syntactic choice in sentence production is a salient topic in psycholinguistics. Existing evidence suggests that syntactic choice results from an interplay between linguistic and non-linguistic factors, and a speaker's attention to the elements of a described event represents one such factor. Whereas multimodal accounts of attention suggest a role for different modalities in this process, existing studies examining attention effects in syntactic choice are primarily based on visual cueing paradigms. Hence, it remains unclear whether attentional effects on syntactic choice are limited to the visual modality or are indeed more general. This issue is addressed by the current study. Native English participants viewed and described line drawings of simple transitive events while their attention was directed to the location of the agent or the patient of the depicted event by means of either an auditory (monaural beep) or a motor (unilateral key press) lateral cue. Our results show an effect of cue location, with participants producing more passive-voice descriptions in the patient-cued conditions. Crucially, this cue location effect emerged in the motor-cue but not (or substantially less so) in the auditory-cue condition, as confirmed by a reliable interaction between cue location (agent vs. patient) and cue type (auditory vs. motor). Our data suggest that attentional effects on the speaker's syntactic choices are modality-specific and limited to the visual and motor, but not the auditory, domain.

Large-scale international surveys are important to globally evaluate, monitor, and promote children's mental health. However, use of young children's self-reports in these studies is still controversial. The Dominic Interactive, a computerized DSM-IV–based child mental health self-report questionnaire, has unique characteristics that may make it preeminently appropriate for usage in cross-country comparisons. This study aimed to determine scale score reliabilities (omega) of the Dominic Interactive in a sample of 8,135 primary school children, ages 6–11 years old, in 7 European countries, to confirm the proposed 7-scale factor structure, and to test for measurement invariance of scale and item scores across countries. Omega reliability values for scale scores were good to high in every country, and the factor structure was confirmed for all countries. A thorough examination of measurement invariance provided evidence for cross-country test score comparability of 5 of the 7 scales and partial scale score invariance of 2 anxiety scales. Possible explanations for this partial invariance include cross-country differences in conceptualizing items and defining what is socially and culturally acceptable anxiety. The convincing evidence for validity of score interpretation makes the Dominic Interactive an indispensable tool for cross-country screening purposes. PMID:26237209

INDIVIDUAL DIFFERENCES IN IMPULSIVE CHOICE AND TIMING IN RATS

2012-01-01

Individual differences in impulsive choice behavior have been linked to a variety of behavioral problems including substance abuse, smoking, gambling, and poor financial decision-making. Given the potential importance of individual differences in impulsive choice as a predictor of behavioral problems, the present study sought to measure the extent of individual differences in a normal sample of hooded Lister rats. Three experiments utilized variations of a delay discounting task to measure the degree of variation in impulsive choice behavior across individual rats. The individual differences accounted for 22–55% of the variance in choice behavior across the three experiments. In Experiments 2 and 3, the individual differences were still apparent when behavior was measured across multiple choice points. Large individual differences in the rate of responding, and modest individual differences in timing of responding were also observed during occasional peak trials. The individual differences in timing and rate, however, did not correlate consistently with individual differences in choice behavior. This suggests that a variety of factors may affect choice behavior, response rate, and response timing. PMID:22851792

In sports, reaction time and anticipatory skill are critical aspects of perceptual abilities. To date, no study has compared reaction time and anticipatory skill of athletes from open and closed skill-dominated sport. Accordingly, the present study investigated whether a difference exists in sensory-cognitive skills between these two different sport domains. Eleven volleyball players and 11 sprinters participated in this experiment. Reaction time and anticipatory skill of both groups were recorded by a custom-made software called SART (speed anticipation and reaction time test). This software consists of six sensory-cognitive tests that evaluate visual choice reaction time, visual complex choice reaction time, auditory choice reaction time, auditory complex choice reaction time, and anticipatory skill of the high speed and low speed of the ball. For each variable, an independent t-test was performed. Results suggested that sprinters were better in both auditory reaction times (P<0.001 for both tests) and volleyball players were better in both anticipatory skill tests (P = 0.007 and P = 0.04 for anticipatory skill of the high speed and low speed of the ball, respectively). However, no significant differences were found in both visual choice reaction time tests (P > 0.05 for both visual reaction time tests). It is concluded that athletes have greater sensory-cognitive skills related to their specific sport domain either open or closed.

Neuroforecasting Aggregate Choice

Knutson, Brian; Genevsky, Alexander

2018-01-01

Advances in brain-imaging design and analysis have allowed investigators to use neural activity to predict individual choice, while emerging Internet markets have opened up new opportunities for forecasting aggregate choice. Here, we review emerging research that bridges these levels of analysis by attempting to use group neural activity to forecast aggregate choice. A survey of initial findings suggests that components of group neural activity might forecast aggregate choice, in some cases even beyond traditional behavioral measures. In addition to demonstrating the plausibility of neuroforecasting, these findings raise the possibility that not all neural processes that predict individual choice forecast aggregate choice to the same degree. We propose that although integrative choice components may confer more consistency within individuals, affective choice components may generalize more broadly across individuals to forecast aggregate choice.

Provencher, Véronique; Jacob, Raphaëlle

2016-03-01

Healthy eating is an important determinant of health, but adherence to dietary guidelines remains a public health concern. Identifying factors that impact dietary habits is therefore important to facilitate healthy eating. One widely used strategy to help consumers make healthier food choices is nutrition information, such as labeling and claims. Despite the intention of these strategies to improve decision making, they can also be misunderstood or misinterpreted by consumers. The aim of this review is to explore food perceptions by examining how cognitive factors influence perceived healthiness of food, and the impact of perceived healthiness of food on food choices and intake. Overall findings of this review suggest that cognitive factors, such as type of food and branding, significantly contribute to judgmental bias and have an impact on perceived healthiness while not consistently or systematically influencing choice and intake.

The public's opinions of physicians: do perceived choice and exercised choice matter?

PubMed

Tai-Seale, Ming; Pescosolido, Bernice

2003-09-01

To assess whether the public's opinions of physicians are affected by one's perceived ability to choose providers and by past experience with switching providers or health plans. Cross-sectional survey of the American general public in 1998. Multivariate quantitative analyses of opinions according to respondents' perceived ability to choose providers, history of exercising choice of providers or plans, and health status. Exploratory factor analyses resulted in 4 scales of opinions: trusting personal physician, positive opinions of physicians as a group, negative opinions of physicians as a group, and concerns about the influence of managed care on personal physicians' practice patterns. Although 75% (879/1172) of the sample perceived that they could use any physician they wanted, only 20% had ever switched health providers or plans owing to dissatisfaction. Perceived lack of choice is associated with lower levels of trust in personal physicians and with higher levels of concern about the influence of managed care on personal physicians. Individuals who have not switched in the past are more positive about physicians as a group and are less concerned about the influence of managed care. Health status affected opinions significantly. Educational attainment is negatively associated with opinions. The public's opinions of physicians are significantly associated with one's perceived ability to choose any provider, past experience with switching health providers or plans, health status, and education. Ensuring consumer choice of providers and targeting those who have switched in the past and the sick could potentially improve the public's opinions. Meaningful provider quality information is necessary to ensure choices that can enhance consumer welfare.

Whole Exome Sequencing in Dominant Cataract Identifies a New Causative Factor, CRYBA2, and a Variety of Novel Alleles in Known Genes

Pediatric cataracts are observed in 1–15 per 10,000 births with 10–25% of cases attributed to genetic causes; autosomal dominant inheritance is the most commonly observed pattern. Since the specific cataract phenotype is not sufficient to predict which gene is mutated, whole exome sequencing (WES) was utilized to concurrently screen all known cataract genes and to examine novel candidate factors for a disease-causing mutation in probands from 23 pedigrees affected with familial dominant cataract. Review of WES data for 36 known cataract genes identified causative mutations in nine pedigrees (39%) in CRYAA, CRYBB1, CRYBB3, CRYGC (2), CRYGD, GJA8 (2), and MIP and an additional likely causative mutation in EYA1; the CRYBB3 mutation represents the first dominant allele in this gene and demonstrates incomplete penetrance. Examination of crystallin genes not yet linked to human disease identified a novel cataract gene, CRYBA2, a member of the βγ-crystallin superfamily. The p.(Val50Met) mutation in CRYBA2 cosegregated with disease phenotype in a four-generation pedigree with autosomal dominant congenital cataracts with incomplete penetrance. Expression studies detected cryba2 transcripts during early lens development in zebrafish, supporting its role in congenital disease. Our data highlight the extreme genetic heterogeneity of dominant cataract as the eleven causative/likely causative mutations affected nine different genes and the majority of mutant alleles were novel. Furthermore, these data suggest that less than half of dominant cataract can be explained by mutations in currently known genes. PMID:23508780

Medical education experiences, particularly in clinical years, are reported determinants of career choice. Less is known about features of clinical education experiences including length, discipline, setting and choice, which may serve as landmarks in career choice decisions. This study's purpose was to explore the benefits of a free choice clerkship elective, and more specifically, its role in clarifying career choice. Using framework and content analysis methodology, we analysed University of British Columbia, third-year medical student anonymised assignments regarding free choice and 2-week clerkship elective experiences. This clerkship was designed to provide students with clerkship experiences outside the conventional curricular model, while encouraging student choice of ambulatory and community settings. Assignment questions included: reasons for choosing elective; whether learning objectives were met; influence of elective on career choice; and unique elective experiences. Iterative review, coding, analysis and indexing of assignments were carried out to identify themes and corroborate findings. Emergent themes included: positive views of experience; transferable knowledge and skills; and influencer of future education and career choices. Although students were encouraged to choose clerkship experiences outside the conventional curricular model, most students chose the elective to clarify future career decisions. This qualitative descriptive study highlights the influence of highly regarded, free choice clerkship elective experiences in the career decision making process in medical education. Further examination of the details of clerkship elective experiences which influence career choice is recommended.

Primacy of memory linkage in choice among valued objects.

PubMed

Jones, Gregory V; Martin, Maryanne

2006-12-01

Three psychological levels at which an object may be processed have been characterized by Norman (2004) in terms of the object's appearance, its usability, and its capacity to elicit memories. A series of experiments was carried out to investigate participants' choices among valued objects recalled in accordance with these three criteria. It was found consistently that objects selected for their capacity to elicit memories--here termed mnemoactive objects--were valued significantly more than the other objects. Even the financial or social importance of an object was outweighed by the importance of its memory link; possible implications for the economic analysis of subjective well-being are briefly discussed. The same pattern of mnemoactive dominance was found across age and gender. Appropriate choice of objects may allow an individual to exert a degree of indirect voluntary control over the activation of involuntary autobiographical memories, providing a new perspective on Proust's approach to memory.

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.

The travel mode of children changed significantly over the last 20 years, with a decrease of children travelling as pedestrians or cyclists. This study focuses on six to twelve year old children. Parents determine to a large extent the mode choice of children in this age category. Based on the analysis of an extensive survey, the research shows that traffic infrastructure has a significant impact on parental decision making concerning children's travel mode choice, by affecting both the real and the perceived traffic safety. Real traffic safety is quantified in terms of numbers of accidents and road infrastructure. For the perceived traffic safety a parental allowance probability is calculated per road type to show that infrastructure characteristics influence parental decision making on the children's mode choice. A binary logistic model shows that this allowance is determined by age, gender and traffic infrastructure near the child's home or near destinations frequently visited by children. Since both real and perceived traffic safety are influenced by infrastructure characteristics, a spatial analysis of parental perception and accident statistics can be used to indicate the locations where infrastructure improvements will be most effective to increase the number of children travelling - safely - as pedestrians or cyclists.

Summary Recent studies of behavioral choice support the notion that the decision to carry out one behavior rather than another depends on the reconfiguration of shared interneuronal networks [1]. We investigated another decision-making strategy, derived from the classical ethological literature [2, 3], which proposes that behavioral choice depends on competition between autonomous networks. According to this model, behavioral choice depends on inhibitory interactions between incompatible hierarchically organized behaviors. We provide evidence for this by investigating the interneuronal mechanisms mediating behavioral choice between two autonomous circuits that underlie whole-body withdrawal [4, 5] and feeding [6] in the pond snail Lymnaea. Whole-body withdrawal is a defensive reflex that is initiated by tactile contact with predators. As predicted by the hierarchical model, tactile stimuli that evoke whole-body withdrawal responses also inhibit ongoing feeding in the presence of feeding stimuli. By recording neurons from the feeding and withdrawal networks, we found no direct synaptic connections between the interneuronal and motoneuronal elements that generate the two behaviors. Instead, we discovered that behavioral choice depends on the interaction between two unique types of interneurons with asymmetrical synaptic connectivity that allows withdrawal to override feeding. One type of interneuron, the Pleuro-Buccal (PlB), is an extrinsic modulatory neuron of the feeding network that completely inhibits feeding when excited by touch-induced monosynaptic input from the second type of interneuron, Pedal-Dorsal12 (PeD12). PeD12 plays a critical role in behavioral choice by providing a synaptic pathway joining the two behavioral networks that underlies the competitive dominance of whole-body withdrawal over feeding.

Sexual selection and the opportunity cost of free mate choice.

PubMed

2016-06-01

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.

Employment and choice-making for adults with intellectual disability, autism, and down syndrome.

Adults with disabilities are employed at a significantly lower rate than adults without disabilities. Of adults with disabilities in the workforce, more individuals work in a facility setting rather than a community setting, despite efforts to improve community inclusion. Choice-making has been proposed as a predictive factor for employment for individuals with disabilities. The purpose of this research was to examine the current state of employment for three groups of adults with intellectual disability (ID): individuals with autism spectrum disorder (ASD), individuals with Down syndrome (DS), and individuals with idiopathic ID. Choice-making and its relation to improved employment outcomes was explored. This study used National Core Indicator's Adult Consumer Survey datasets from years 2011-2012 and 2012-2013. Factor analyses revealed latent variables from six choice-making questions in the Adult Consumer Survey. Ordinal logistic regression was used to identify factors related to employment status. Adults with DS had the highest rates of paid community jobs, but adults with ID had the highest rates of choice-making. ID severity level and short-term choice-making had the greatest effects on employment status in all three groups. Employment rates remain low despite national efforts to find jobs for people with disabilities. Choice-making is a unique factor that was found to be associated with employment status and provides a target for interventions to increase employability. Copyright © 2017 Elsevier Ltd.

Urban areas are the clear, dominant source of global fossil fuel CO2 emissions. However, urban areas are also a heterogeneous mix of biological CO2 sources and sinks. The magnitude and timing of sources and sinks varies diurnally and seasonally with phenology, climate, and nitrogen inputs. Both the anthropogenic and biological CO2 fluxes are highly sensitive to management choices. We present results quantifying the role of management preferences and land use decisions in influencing biological CO2 fluxes across a gradient of urban development. Specifically, we explore the fluxes from soil respiration, plant growth, and the role of nitrogen deposition and amendments across urban gradients.

This study investigated the interactive effects of friend deviance and reward dominance on the development of externalizing behavior of adolescents in the Child Development Project. Reward dominance was assessed at age 16 by performance on a computer-presented card-playing game in which participants had the choice of either continuing or discontinuing the game as the likelihood of reward decreased and the likelihood of punishment increased. At ages 14 and 16, friend deviance and externalizing behavior were assessed through self-report. As expected, based on motivational balance and response modulation theories, path analysis revealed that age 14 friend deviance predicted age 16 externalizing behavior controlling for age 14 externalizing behavior. Reward dominance was a significant moderator of the relationship between friend deviance and externalizing behavior. The contributions of deviant friends to the development of externalizing behavior were enhanced by adolescents' reward dominance.

The number of student enrolments in computer-related courses remains a serious concern worldwide with far reaching consequences. This paper reports on an extensive survey about career choice and associated motivational factors amongst new students, only some of whom intend to major in computer-related courses, at two South African universities. The data were analyzed using some components of Social Cognitive Career Theory, namely external influences, self-efficacy beliefs and outcome expectations. The research suggests the need for new strategies for marketing computer-related courses and the avenues through which they are marketed. This can to some extent be achieved by studying strategies used by other (non-computer) university courses, and their professional bodies. However, there are also distinct differences, related to self-efficacy and career outcomes, between the computer majors and the `other' group and these need to be explored further in order to find strategies that work well for this group. It is not entirely clear what the underlying reasons are for these differences but it is noteworthy that the perceived importance of "Interest in the career field" when choosing a career remains very high for both groups of students.

The dominance behavioral system and manic temperament: Motivation for dominance, self-perceptions of power, and socially dominant behaviors

PubMed Central

Johnson, Sheri L.; Carver, Charles S.

2013-01-01

The dominance behavioral system has been conceptualized as a biologically based system comprising motivation to achieve social power and self-perceptions of power. Biological, behavioral, and social correlates of dominance motivation and self-perceived power have been related to a range of psychopathological tendencies. Preliminary evidence suggests that mania and risk for mania (manic temperament) relate to the dominance system. Method Four studies examine whether manic temperament, measured with the Hypomanic Personality Scale (HPS), is related to elevations in dominance motivation, self-perceptions of power, and engagement in socially dominant behavior across multiple measures. In Study 1, the HPS correlated with measures of dominance motivation and the pursuit of extrinsically-oriented ambitions for fame and wealth among 454 undergraduates. In Study 2, the HPS correlated with perceptions of power and extrinsically-oriented lifetime ambitions among 780 undergraduates. In Study 3, the HPS was related to trait-like tendencies to experience hubristic (dominance-related) pride, as well as dominance motivation and pursuit of extrinsically-oriented ambitions. In Study 4, we developed the Socially Dominant Behavior Scale to capture behaviors reflecting high power. The scale correlated highly with the HPS among 514 undergraduates. Limitations The studies rely on self-ratings of manic temperament and dominance constructs, and findings have not yet been generalized to a clinical sample. Conclusions Taken together, results support the hypothesis that manic temperament is related to a focus on achieving social dominance, ambitions related to achieving social recognition, perceptions of having achieved power, tendencies to experience dominance-related pride, and engagement in social behaviors consistent with this elevated sense of power.

Dominant factors controlling glacial and interglacial variations in the treeline elevation in tropical Africa

2007-01-01

The knowledge of tropical palaeoclimates is crucial for understanding global climate change, because it is a test bench for general circulation models that are ultimately used to predict future global warming. A longstanding issue concerning the last glacial maximum in the tropics is the discrepancy between the decrease in sea-surface temperatures reconstructed from marine proxies and the high-elevation decrease in land temperatures estimated from indicators of treeline elevation. In this study, an improved inverse vegetation modeling approach is used to quantitatively reconstruct palaeoclimate and to estimate the effects of different factors (temperature, precipitation, and atmospheric CO2 concentration) on changes in treeline elevation based on a set of pollen data covering an altitudinal range from 100 to 3,140 m above sea level in Africa. We show that lowering of the African treeline during the last glacial maximum was primarily triggered by regional drying, especially at upper elevations, and was amplified by decreases in atmospheric CO2 concentration and perhaps temperature. This contrasts with scenarios for the Holocene and future climates, in which the increase in treeline elevation will be dominated by temperature. Our results suggest that previous temperature changes inferred from tropical treeline shifts may have been overestimated for low-CO2 glacial periods, because the limiting factors that control changes in treeline elevation differ between glacial and interglacial periods.

2013-02-01

Given the trend among medical students away from primary care medicine and toward specialties that allow for more controllable lifestyles, the identification of factors associated with specialty choice is important. Burnout is one such factor. The purpose of this study was to examine the associations between burnout and residency specialty choice in terms of provision for a less versus more controllable lifestyle (e.g. internal medicine versus dermatology) and a lower versus higher income (e.g. paediatrics versus anaesthesiology). A survey was sent to 165 Year 4 medical students who had entered the residency matching system. Students answered questions about specialty choice, motivating factors (lifestyle, patient care and prestige) and perceptions of medicine as a profession. They completed the Maslach Burnout Inventory-Human Services (MBI), which defines burnout in relation to emotional exhaustion (EE), depersonalisation (DP) and personal accomplishment (PA). Burnout and other variables were tested for associations with specialty lifestyle controllability and income. A response rate of 88% (n = 145) was achieved. Experiences of MBI-EE, MBI-DP and MBI-PA burnout were reported by 42 (29%), 26 (18%) and 30 (21%) students, respectively. Specialties with less controllable lifestyles were chosen by 87 (60%) students and lower-income specialties by 81 (56%). Adjusted odds ratios (ORs) indicated that the choice of a specialty with a more controllable lifestyle was associated with higher MBI-EE burnout (OR = 1.77, 95% confidence interval [CI] 1.06-2.96), as well as stronger lifestyle- and prestige-related motivation, and weaker patient care-related motivation. The choice of a higher-income specialty was associated with lower MBI-PA burnout (OR = 0.56, 95% CI 0.32-0.98), weaker lifestyle- and patient care-related motivation, and stronger prestige-related motivation. Specialty choices regarding lifestyle controllability and income were associated with the amount and type of

Not all choices are created equal: Task-relevant choices enhance motor learning compared to task-irrelevant choices.

Lewthwaite et al. (2015) reported that the learning benefits of exercising choice (i.e., their self-controlled condition) are not restricted to task-relevant features (e.g., feedback). They found that choosing one's golf ball color (Exp. 1) or choosing which of two tasks to perform at a later time plus which of two artworks to hang (Exp. 2) resulted in better retention than did being denied these same choices (i.e., yoked condition). The researchers concluded that the learning benefits derived from choice, whether irrelevant or relevant to the to-be-learned task, are predominantly motivational because choice is intrinsically rewarding and satisfies basic psychological needs. However, the absence of a group that made task-relevant choices and the lack of psychological measures significantly weakened their conclusions. Here, we investigated how task-relevant and task-irrelevant choices affect motor-skill learning. Participants practiced a spatiotemporal motor task in either a task-relevant group (choice over feedback schedule), a task-irrelevant group (choice over the color of an arm-wrap plus game selection), or a no-choice group. The results showed significantly greater learning in the task-relevant group than in both the task-irrelevant and no-choice groups, who did not differ significantly. Critically, these learning differences were not attributed to differences in perceptions of competence or autonomy, but instead to superior error-estimation abilities. These results challenge the perspective that motivational influences are the root cause of self-controlled learning advantages. Instead, the findings add to the growing evidence highlighting that the informational value gained from task-relevant choices makes a greater relative contribution to these advantages than motivational influences do.

The main objective of this study was to determine the motives underlying the selection of foods between husbands and wives in an urban community. Thiscross-sectional study was carried out in Bandar Baru Bangi, Selangor, Malaysia among 150 married couples aged 20 and above, who voluntarily agreed to participate and were not on any special diet. Data were collected using the Food Choice Questionnaire (FCQ) which measured the health-related and non health related factor that influence people's food choices. It consisted of 36 items designed to assess the reported importance of nine factors: health, mood, convenience, sensory appeal, natural content, price, weight control, familiarity, and ethical concern. In this study, the FCQ was adapted and a new factor, religion (religious guidelines), was included. Demographic characteristics including age, occupation, education, household income and household size were also collected. Data were analysed using SPSS version 16. Results showed that 40.7% of husbands (mean age= 43.33 + 11.16 years) and 55.3% of wives (mean age= 41.28 + 10.93 years) perceived themselves as the main food shopper while 12.0% of the husbands and 85.3% of the wives perceived themselves as the main meal planner. Husbands rated religion as the most prominent factor in food choice motives with a mean average rating of 4.56 + 0.59 on a 5-point rating scale, followed by health and convenience factor. Meanwhile, the wives rated health as the most essential factor with mean average rating of 4.49 + 0.58, followed by religion and convenience factor. Sensory appeal, ethical concerns and familiarity were rated as the bottom three factors of food choice motives among these two groups. Price of foods was not considered as an important factor in making food choices for the subjects in this study. In conclusion, the husbands and wives of this urban community rated religion, health and convenience as the three most important food choice motives in food selection.

Background  The low number of medical trainees entering primary care is contributing to the lack of access to primary care services in many countries. Despite the need for primary care physicians in the Middle East, there is limited information regarding trainees' career choices, a critical determinant in the supply of primary care physicians. Objective  We analyzed the career choices of medical students in the United Arab Emirates (UAE), with a larger goal of reforming postgraduate training in the region and enhancing the focus on primary care. Methods  We conducted a cross-sectional survey of applicants to a large established internal medicine residency program in the UAE. We calculated data for demographics, subspecialty choice, and factors affecting subspecialty choice, and we also reported descriptive statistics. Results  Our response rate was 86% (183 of 212). Only 25% of applicants (n = 46) were interested in general internal medicine. The majority of respondents (n = 126, 69%) indicated a desire to pursue subspecialty training, and the remainder chose careers in research or administration. A majority of respondents (73%) were women, unmarried, and childless. Educational debt or lifestyle were not indicated as important factors in career choice. Conclusions  Low interest in primary care was similar to that in many Western countries, despite a much higher percentage of female applicants and a reduced emphasis on lifestyle or income factors in career decisions. Reasons for the reduced interest in primary care deserve further exploration, as do tests of interventions to increase interest, such as improving the primary care clerkship experience.

Using a standard measure of informed choice, validated for use in Greek, it was found that 44% of women made an informed choice, and thus 56% of women made an uninformed choice. The internal consistency of the scales was good; Cronbach's alpha was found to be 0.76 for the attitude scale and 0.64 for the knowledge scale, suggesting that all items were appropriate to measure. The performed factor analysis of the attitude scale indicated three factors with an eigenvalue over 1.0. Those factors were responsible for 87% of the variance. this study indicates that the Greek version of the MMIC appears to be a reliable and valid tool for measuring informed choice in antenatal screening for Down syndrome. Due to its short length and consumption of time, it seems to be a practical instrument for use in Greek antenatal clinics. Copyright © 2009 Elsevier Ltd. All rights reserved.

Food choice, appetite and physical activity.

Bellisle, F

1999-09-01

Food choices and diet composition have been studied less often than energy intake in subjects with varying levels of physical activity. The reported effects of exercise on food choices are not fully consistent, especially on the short term. Type of exercise, intensity, duration can affect the results as well as subjects' characteristics (gender, age, previous training and fitness). A crucial role could also be played by psychological (chronic dieting, attitudes toward health and food, long-established food habits and preferences) and social (traditions, food availability, appropriate times and places) factors. In short-term intervention studies, where a meal is ingested a few minutes following a bout of exercise of varying duration and intensity, an increase in CHO intake is most often reported, while increased protein intake is an occasional observation. In long-term (several weeks) training interventions, intake is assessed from dietary records. Again CHO intake is augmented in exercised subjects as compared to controls, while that of saturated fats and cholesterol may also be affected. Epidemiological studies (without dietary or exercise intervention) often report that habitually active persons eat more and ingest more fruits and vegetables than less active peers. It is not known to what extent such food choices are driven by biological needs (e.g. replacement of glycogen) or elicited by social and psychological factors.

Residents' Yard Choices and Rationales in a Desert City: Social Priorities, Ecological Impacts, and Decision Tradeoffs

As a dominant land use in urban ecosystems, residential yards impact water and other environmental resources. Converting thirsty lawns into alternative landscapes is one approach to water conservation, yet barriers such as cultural norms reinforce the traditional lawn. Meanwhile, the complex social and ecological implications of yard choices complicate programs aimed at changing grass and other yard features for particular purposes. In order to better understand individual landscape decisions, we qualitatively examined residents’ rationales for their preferred yard types in the desert metropolis of Phoenix, Arizona. After briefly presenting landscape choices across two survey samples, the dominant reasons for preferences are discussed: appearance, maintenance, environment, recreation, microclimate, familiarity, and health/safety. Three broader analytical themes emerged from these descriptive codes: (1) residents’ desires for attractive, comfortable landscapes of leisure encompassing pluralistic tastes, lifestyles, and perceptions; (2) the association of environmental benefits and impacts with different landscape types involving complex social and ecological tradeoffs; and (3) the cultural legacies evident in modern landscape choices, especially in terms of a dichotomous human-nature worldview among long-time residents of the Phoenix oasis. Given these findings, programs aimed at landscape change must recognize diverse preferences and rationalization processes, along with the perceived versus actual impacts and tradeoffs of varying yard alternatives.

Concurrent analysis of choice and control in childbirth

Background This paper reports original research on choice and control in childbirth. Eight women were interviewed as part of a wider investigation into locus of control in women with pre-labour rupture of membranes at term (PROM) [1]. Methods The following study uses concurrent analysis to sample and analyse narrative aspects of relevant literature along with these interviews in order to synthesise a generalisable analysis of the pertinent issues. The original PROM study had found that women experienced a higher degree of control in hospital, a finding that appeared at odds with contemporary notions of choice. However, this paper contextualises this finding by presenting narratives that lucidly subscribe to the dominant discourse of hospital as the safest place to give birth, under the premise of assuring a live healthy baby irrespective of their management type. Results This complex narrative is composed of the following themes: 'perceiving risk', 'being prepared', 'reflecting on experience', maintaining control' and relinquishing control'. These themes are constructed within and around the medical, foetocentric, risk averse cultural context. Primary data are presented throughout to show the origins and interconnected nature of these themes. Conclusions Within this context it is clear that there is a highly valued role for competent health professionals that respect, understand and are capable of facilitating genuine choice for women.

A diet dominated by plant foods, with limited amounts of refined processed foods and animal products conveys substantial health benefits. This study sought to explore adolescents’ attitudes and perceptions towards plant-based foods. Semi-structured focus group interviews were conducted with adolescents (age 14–15 years) (n = 29) attending an inner city school in Yorkshire, UK. Using a grounded theory methodology, data analysis provided four main categories and related concepts revolving around adolescents’ perspectives on plant-based foods: food choice parameters; perceived drivers and benefits of plant-based foods; environmental food cues; barriers to plant-based food choice. In the emergent grounded theory, a clear disconnect between plant-based foods and the parameters that adolescents use to make food choices, is highlighted. Further, key barriers to adolescents adopting a plant-based diet are differentiated and considered with respect to practice and policy. The analysis offers a framework to remodel and re-present plant-based foods. In this way, it is proposed that a closer connection is possible, with consequent shifts in adolescents’ dietary behaviour towards a more plant-based diet and associated health benefits.

Choice-Based Conjoint Analysis: Classification vs. Discrete Choice Models

NASA Astrophysics Data System (ADS)

Giesen, Joachim; Mueller, Klaus; Taneva, Bilyana; Zolliker, Peter

Conjoint analysis is a family of techniques that originated in psychology and later became popular in market research. The main objective of conjoint analysis is to measure an individual's or a population's preferences on a class of options that can be described by parameters and their levels. We consider preference data obtained in choice-based conjoint analysis studies, where one observes test persons' choices on small subsets of the options. There are many ways to analyze choice-based conjoint analysis data. Here we discuss the intuition behind a classification based approach, and compare this approach to one based on statistical assumptions (discrete choice models) and to a regression approach. Our comparison on real and synthetic data indicates that the classification approach outperforms the discrete choice models.

The decision to study physics or astronomy is affected by many factors, including preferences, motivations, and expectations for success. Differing cognitive profiles contribute to the learning of science through a complex process in which intrinsic capacities are tuned both by everyday experience and by instruction. In an attempt to identify the developmental pathways and intrinsic factors that most strongly influence the choice to study science, we administered an extensive survey to a sample of 400 students. The survey questions were based on Eccles et al.’s model of achievement-related choices and findings showing that previous play experiences, spatial experiences, task beliefs, as well as perceived mathematics ability, motivational and personality characteristics affect mathematics achievement and science career choices. The perceptions of students planning a science career are compared with those planning a career in other areas. Gender differences are also discussed.

The Attraction Effect Modulates Reward Prediction Errors and Intertemporal Choices.

PubMed

Gluth, Sebastian; Hotaling, Jared M; Rieskamp, Jörg

2017-01-11

Classical economic theory contends that the utility of a choice option should be independent of other options. This view is challenged by the attraction effect, in which the relative preference between two options is altered by the addition of a third, asymmetrically dominated option. Here, we leveraged the attraction effect in the context of intertemporal choices to test whether both decisions and reward prediction errors (RPE) in the absence of choice violate the independence of irrelevant alternatives principle. We first demonstrate that intertemporal decision making is prone to the attraction effect in humans. In an independent group of participants, we then investigated how this affects the neural and behavioral valuation of outcomes using a novel intertemporal lottery task and fMRI. Participants' behavioral responses (i.e., satisfaction ratings) were modulated systematically by the attraction effect and this modulation was correlated across participants with the respective change of the RPE signal in the nucleus accumbens. Furthermore, we show that, because exponential and hyperbolic discounting models are unable to account for the attraction effect, recently proposed sequential sampling models might be more appropriate to describe intertemporal choices. Our findings demonstrate for the first time that the attraction effect modulates subjective valuation even in the absence of choice. The findings also challenge the prospect of using neuroscientific methods to measure utility in a context-free manner and have important implications for theories of reinforcement learning and delay discounting. Many theories of value-based decision making assume that people first assess the attractiveness of each option independently of each other and then pick the option with the highest subjective value. The attraction effect, however, shows that adding a new option to a choice set can change the relative value of the existing options, which is a violation of the independence

Estimating the mode of inheritance in genetic association studies of qualitative traits based on the degree of dominance index

PubMed Central

2011-01-01

Background The biological justification for the choice of the genetic mode in genetic association studies (GAS) is seldom available. Then, the mode of inheritance is approximated by investigating a number of non-orthogonal genetic contrasts making the interpretation of results difficult. Methods We propose to define the mode of inheritance by the significance of the deviance of the co-dominant contrast and the degree of dominance (h), which is a function of two orthogonal contrasts (the co-dominant and additive). Non-dominance exists when the co-dominant contrast is non-significant and, hence, the risk effect of heterozygotes lies in the middle of the risk of the two homozygotes. Otherwise, dominance (including over- and under-dominance) is present and the direction of dominance depends on the value of h. Results Simulations show that h may capture the real mode of inheritance and it is affected by deviations from Hardy-Weinberg equilibrium (HWE). In addition, power for detecting significance of h when the study conforms to HWE rule increases with the degree of dominance and to some extent is related to the mutant allele frequency. Conclusion The introduction of the degree of dominance provides useful insights into the mode of inheritance in GAS. PMID:22188898

The Interactive Influences of Friend Deviance and Reward Dominance on the Development of Externalizing Behavior During Middle Adolescence

Bates, John E.; Newman, Joseph P.; Dodge, Kenneth A.; Pettit, Gregory S.

2009-01-01

This study investigated the interactive effects of friend deviance and reward dominance on the development of externalizing behavior of adolescents in the Child Development Project. Reward dominance was assessed at age 16 by performance on a computer-presented card-playing game in which participants had the choice of either continuing or discontinuing the game as the likelihood of reward decreased and the likelihood of punishment increased. At ages 14 and 16, friend deviance and externalizing behavior were assessed through self-report. As expected, based on motivational balance and response modulation theories, path analysis revealed that age 14 friend deviance predicted age 16 externalizing behavior controlling for age 14 externalizing behavior. Reward dominance was a significant moderator of the relationship between friend deviance and externalizing behavior. The contributions of deviant friends to the development of externalizing behavior were enhanced by adolescents' reward dominance. PMID:16823636

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

PubMed

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.

Male dominance rank, mating and reproductive success in captive bonobos (Pan paniscus).

2006-01-01

In the recent past, application of DNA genotyping techniques has enabled researchers to more accurately test relationships between dominance rank (DR), mating success (MS) and reproductive success (RS). Paternity studies often reveal that reproductive outcome does not always correlate with male DR and/or MS and thus open room for discussion and interpretation of alternative reproductive tactics of both sexes. In this study, we analysed male DR, MS and RS in a group of bonobos at Twycross Zoo (UK). Genetic relationships were determined using 8 tetrameric microsatellite loci. Despite clear and asymmetric dominance relationships, analysed using normalised David's scores based on a dyadic index of dominance among the group's 3 mature males, we found that the most dominant male did not sire the most offspring. In fact, both infants conceived during the observation period were found to be sired by the lower-ranking males. Although the alpha male had almost exclusive mating access to one of the females during the time she was showing a maximal anogenital swelling, her infant was sired by the lowest-ranking male who mostly mated with her when outside the maximal swelling period. This result suggests that either sperm competition operates and/or ovulation is decoupled from the phase of maximal anogenital swelling which could allow greater female choice. Copyright 2006 S.

Hui, Amy Leung; Sevenhuysen, Gustaaf; Harvey, Dexter; Salamon, Elizabeth

2014-02-01

To enhance the dietary education presented to women with gestational diabetes (GDM) by exploring the reasons and experiences that women with GDM reported in making their food-choice decisions after receipt of dietary education from a healthcare professional. Food Choice Map (FCM) semi-structured in-depth interviews were conducted with 30 women with GDM living in the Winnipeg area during their pregnancies. Verbatim transcripts were generated from the interviews. A constant comparative method was used to generate common themes to answer research inquiries. Personal food preferences, hunger and cravings were the main factors affecting food choice decision-making in women with GDM. Although the information from healthcare professionals was 1 factor that affected food choice decision-making for most of the participants, more than half of the women, including all the women who were on insulin, reported difficulties in quick adaptation to dietary management in a limited time period. Information from other sources such as family members, friends, and internet were used to cope with the adaptation. These difficulties led to a sense of decreased control of GDM and were accompanied by frustration, especially for women taking insulin. Food choice decision-making varied for this group of women with GDM. Knowledge and information aided in making healthy food choices and in portion control. However, balancing individual needs and blood glucose control in a short time period was felt to be difficult and created frustration. The findings suggested that dietary consultation needs to be personalized and to be time sensitive to promote confidence in self-control. Copyright © 2014 Canadian Diabetes Association.

The objective of this study is to identify the variables that affect young urologists' productivity and academic career choice. We have conducted an internet-based national survey for urologists randomly sampled from the database of Turkish Urological Association and 110 physicians completed this survey. Participants were asked to answer three-page questionnaire including 37 questions, which takes around 5 min to complete. Questionnaire was consisting of four main sections: 'demography', 'education', 'working conditions' and 'quality of life'. Increased dedicated research time, being interested in an academic career, being Fellow of the European Board of Urology (FEBU), having English proficiency, and greater numbers of manuscript publication during residency were associated with increased productivity after residency (p = 0.001, p = 0.028, p = 0.046, p<0.001 and p<0.001, respectively). The remaining variables including age at marriage, age at having a child, monthly salary, length of residency, having a mentor or role model during residency showed no significant relationship with manuscript publications. Twenty-nine physicians (26.4%) stated that they had once been interested in their residency but were no longer interested in academic urology. Reasons for this loss of academic interest included lack of effective mentor or role model (27.2%), bureaucracy (17%), financial issues (13.6%), mandatory rule to work in public hospitals (18.2%) or military hospitals (9%) and language problems (21.6%). Our data indicate that increased time spent for research, being interested in an academic career, being an FEBU, having English proficiency, and greater publication during residency were associated with increased numbers of publications and academic career choice.

Bacterial and fungal infections in pediatric oncology patients cause morbidity and mortality. The clinical utility of antimicrobial prophylaxis in children is uncertain and the personal utility of these agents is disputed. Objectives were to use a discrete choice experiment to: (1) describe the importance of attributes to parents and healthcare providers when deciding between use and non-use of antibacterial and antifungal prophylaxis; and (2) estimate willingness-to-pay for prophylactic strategies. Attributes were chances of infection, death and side effects, route of administration and cost of pharmacotherapy. Respondents were randomized to a discrete choice experiment outlining hypothetical treatment options to prevent antibacterial or antifungal infections. Each respondent was presented 16 choice tasks and was asked to choose between two unlabeled treatment options and an opt-out alternative (no prophylaxis). 102 parents and 60 healthcare providers participated. For the antibacterial discrete choice experiment, frequency of administration was significantly associated with utility for parents but not for healthcare providers. Increasing chances of infection, death, side effects and cost were all significantly associated with decreased utility for parents and healthcare providers in both the antibacterial and antifungal discrete choice experiment. Parental willingness-to-pay was higher than healthcare providers for both strategies. Chances of infection, death, side effects and costs were all significantly associated with utility. Parents have higher willingness-to-pay for these strategies compared with healthcare providers. This knowledge can help to develop prophylaxis programs.

Action and Valence Modulate Choice and Choice-Induced Preference Change

PubMed Central

Koster, Raphael; Duzel, Emrah; Dolan, Raymond J.

2015-01-01

Choices are not only communicated via explicit actions but also passively through inaction. In this study we investigated how active or passive choice impacts upon the choice process itself as well as a preference change induced by choice. Subjects were tasked to select a preference for unfamiliar photographs by action or inaction, before and after they gave valuation ratings for all photographs. We replicate a finding that valuation increases for chosen items and decreases for unchosen items compared to a control condition in which the choice was made post re-evaluation. Whether choice was expressed actively or passively affected the dynamics of revaluation differently for positive and negatively valenced items. Additionally, the choice itself was biased towards action such that subjects tended to choose a photograph obtained by action more often than a photographed obtained through inaction. These results highlight intrinsic biases consistent with a tight coupling of action and reward and add to an emerging understanding of how the mode of action itself, and not just an associated outcome, modulates the decision making process.

Development of a measure of the motives underlying the selection of food: the food choice questionnaire.

1995-12-01

A number of factors are thought to influence people's dietary choices, including health, cost, convenience and taste, but there are no measures that address health-related and non-health-related factors in a systematic fashion. This paper describes the development of a multidimensional measure of motives related to food choice. The Food Choice Questionnaire (FCQ) was developed through factor analysis of responses from a sample of 358 adults ranging in age from 18 to 87 years. Nine factors emerged, and were labelled health, mood, convenience, sensory appeal, natural content, price, weight control, familiarity and ethical concern. The questionnaire structure was verified using confirmatory factor analysis in a second sample (n = 358), and test-retest reliability over a 2- to 3-week period was satisfactory. Convergent validity was investigated by testing associations between FCQ scales and measures of dietary restraint, eating style, the value of health, health locus of control and personality factors. Differences in motives for food choice associated with sex, age and income were found. The potential uses of this measure in health psychology and other areas are discussed.

Consistent individual differences in behavioral tendencies (animal personality) can affect individual mate choice decisions. We asked whether personality traits affect male and female mate choice decisions similarly and whether potential personality effects are consistent across different mate choice situations. Using western mosquitofish (Gambusia affinis) as our study organism, we characterized focal individuals (males and females) twice for boldness, activity, and sociability/shoaling and found high and significant behavioral repeatability. Additionally, each focal individual was tested in two different dichotomous mate choice tests in which it could choose between computer-animated stimulus fish of the opposite sex that differed in body size and activity levels, respectively. Personality had different effects on female and male mate choice: females that were larger than average showed stronger preferences for large-bodied males with increasing levels of boldness/activity (i.e., towards more proactive personality types). Males that were larger than average and had higher shoaling tendencies showed stronger preferences for actively swimming females. Size-dependent effects of personality on the strength of preferences for distinct phenotypes of potential mating partners may reflect effects of age/experience (especially in females) and social dominance (especially in males). Previous studies found evidence for assortative mate choice based on personality types or hypothesized the existence of behavioral syndromes of individuals' choosiness across mate choice criteria, possibly including other personality traits. Our present study exemplifies that far more complex patterns of personality-dependent mate choice can emerge in natural systems.

It is questionable whether socioeconomic factors influence the choice of marketed children’s dentifrices and whether these products are associated with greater fluoride (F) intake in children. The present cross-sectional study involving 197 children (mean age: 40.98 ± 6.62 months) was carried out in Montes Claros, Brazil. Parents completed a questionnaire on socioeconomic status and the tooth brushing habits of their children. The children brushed their teeth and saliva residues were collected for F analysis. F intake from dentifrice was determined with an ion-specific electrode. Univariate analysis and logistic regression were used to test whether the type of dentifrice (children’s or family) and F dose (<0.05 and ≥0.05 mg F/Kg of body weight/day) were associated with the independent variables (p < 0.05). No differences were found between children’s and family dentifrices regarding daily F intake (0.046 and 0.040 mg F/Kg/day, respectively; p = 0.513). The following were strong predictors for the use of a children’s dentifrice: studying at a private kindergarten (OR: 6.89; p < 0.001); age that the child begun to tooth brush <2 years (OR: 2.93; p = 0.041), and the interaction between the variables “use of the same dentifrice as parents” and “type of tooth brush used” (OR: 27.20; p < 0.001). “The amount of dentifrice used” and “frequency of tooth brushing” (p ≤ 0.004) had a statistically and synergistic effect over the daily F dose. The present study found a social influence over the choice of dentifrice: children with a high socioeconomic status tend to use a children’s dentifrice. The amount of dentifrice used can strongly increase the risk of exposure to higher doses of F, regardless of the type of dentifrice. PMID:22163207

The microvasculature within the neural stem cell (NSC) niche promotes self-renewal and regulates lineage progression. Previous work identified endothelial-produced soluble factors as key regulators of neural progenitor cell (NPC) fate and proliferation; however, endothelial cells (ECs) are sensitive to local hemodynamics, and the effect of this key physiological process has not been defined. In this study, we evaluated adult mouse NPC response to soluble factors isolated from static or dynamic (flow) EC cultures. Endothelial factors generated under dynamic conditions significantly increased neuronal differentiation, while those released under static conditions stimulated oligodendrocyte differentiation. Flow increases EC release of neurogenic factors and of heparin sulfate glycosaminoglycans that increase their bioactivity, likely underlying the enhanced neuronal differentiation. Additionally, endothelial factors, especially from static conditions, promoted adherent growth. Together, our data suggest that blood flow may impact proliferation, adhesion, and the neuron-glial fate choice of adult NPCs, with implications for diseases and aging that reduce flow.

Factors affecting placement of a child with intellectual disability.

Kandel, Isack; Merrick, Joav

2005-05-06

Parents of disabled children often face the question whether or not to keep the child at home or to place them. The choice between the two alternatives resides with the parents and various factors influence their decision. Several researchers have identified these factors, which include child-related parameters, family and parental attitudes, the influence of the social environment, and the external assistance provided to the family. In a pilot study, we attempted to isolate the main factors involved in the parental decision either to keep the child at home or place the child by examining a sample comprised of 50 parents of children suffering severe intellectual disability studying in a special education school and 48 parents of adults with intellectual disability working in sheltered workshops. Each parent filled out a questionnaire used in a study in the United States and results of the research indicated parental-related factors as the dominant factors that delayed the placement of their child in residential care; guilt feelings were the main factor.

Choice in experiential learning: True preferences or experimental artifacts?

Ashby, Nathaniel J S; Konstantinidis, Emmanouil; Yechiam, Eldad

2017-03-01

The rate of selecting different options in the decisions-from-feedback paradigm is commonly used to measure preferences resulting from experiential learning. While convergence to a single option increases with experience, some variance in choice remains even when options are static and offer fixed rewards. Employing a decisions-from-feedback paradigm followed by a policy-setting task, we examined whether the observed variance in choice is driven by factors related to the paradigm itself: Continued exploration (e.g., believing options are non-stationary) or exploitation of perceived outcome patterns (i.e., a belief that sequential choices are not independent). Across two studies, participants showed variance in their choices, which was related (i.e., proportional) to the policies they set. In addition, in Study 2, participants' reported under-confidence was associated with the amount of choice variance in later choices and policies. These results suggest that variance in choice is better explained by participants lacking confidence in knowing which option is better, rather than methodological artifacts (i.e., exploration or failures to recognize outcome independence). As such, the current studies provide evidence for the decisions-from-feedback paradigm's validity as a behavioral research method for assessing learned preferences. Copyright © 2017 Elsevier B.V.

As the only connecting term between water balance and energy budget in the earth-atmospheric system, evapotranspiration (ET) is considered the most excellent indicator for the activity for the water and energy cycle. Under the background of global change, regional ET estimates, components partitioning as well as their spatial and temporal patterns recognition are of great importance in understanding the hydrological processes and improving water management practices. This is particularly true for the Tibetan Plateau (TP), one of most sensitive and vulnerable region in response to the environment change in the earth. In this study, with flux site observation data and monthly ET data from the monthly water balance method incorporating the terrestrial water storage changes from the Gravity Recovery and Climate Experiment satellite (GRACE) production as the multiple validations, the long-term daily ET in the TP was retrieved by a modified Penman-Monteith-Leuning (PML) model with considering evapotranspiration over snow covered area during 1982-2012. The spatial and temporal changes of partitioned three components of ET, i.e., soil evaporation (Es), transpiration through the stomata of plant (Ec) and canopy interception (Ei), were investigated in the TP. Meanwhile, how the ET components contribute to ET changes and respond to the change in environmental factors in the TP was revealed and discussed. The results indicate that Es dominates ET in most areas of the TP with the mean annual ratio of 65.7%, except southeastern regions where the vegetation coverage is high. Although regional average ET and three main components all present obvious increase trends during the past decades, high spatial heterogeneity for their trends are identified in the TP. Moreover, a mixed changing pattern can be apparently found for Es in southeastern area, Ec and Ei in northwestern and southeastern area. Spatially, the ET variation are mainly attributed to change in Es, followed by Ec and Ei

Factors that influence reinforcer choice have been examined in a number of applied studies (e.g., Neef, Mace, Shea, & Shade, 1992; Shore, Iwata, DeLeon, Kahng, & Smith, 1997; Tustin, 1994). However, no applied studies have evaluated the effects of postsession reinforcement on choice between concurrently available reinforcers, even though basic findings indicate that this is an important factor to consider (Hursh, 1978; Zeiler, 1999). In this bridge investigation, we evaluated the influence of postsession reinforcement on choice of two food items when task responding was reinforced on progressive-ratio schedules. Participants were 3 children who had been diagnosed with developmental disabilities. Results indicated that response allocation shifted from one food item to the other food item under thinner schedules of reinforcement when no postsession reinforcement was provided. These findings suggest that the efficacy of instructional programs or treatments for problem behavior may be improved by restricting reinforcers outside treatment sessions.

Public relations activities for all organizations can have an important effect on consumer decision-making when buying goods or services. This study examines the effect that public relations activities can have regarding consumer decisions and choice. To explore exemplify this relationship a questionnaire was given to 971 patients within public, university and private hospitals in Ankara, Turkey. Study results show that public relations activities were a crucial factor in determining consumer hospital choice. The majority of respondents reported that the behaviors and attitude of personnel as public relations activities that support the hospital's reputation within the public were the primary variables in hospital choice. Health care managers can use these findings to further understand how patients make informed choices related to usage of a health care facility and to develop and/or improve public relations activities.

Social groups are organized along dominance hierarchies, which determine how we respond to threats posed by dominant and subordinate others. The persuasive impact of these dominance threats on mental and physical well-being has been well described but it is unknown how dominance rank of others bias our experience and learning in the first place. We introduce a model of conditioned social dominance threat in humans, where the presence of a dominant other is paired with an aversive event. Participants first learned about the dominance rank of others by observing their dyadic confrontations. During subsequent fear learning, the dominant and subordinate others were equally predictive of an aversive consequence (mild electric shock) to the participant. In three separate experiments, we show that participants’ eye-blink startle responses and amygdala reactivity adaptively tracked dominance of others during observation of confrontation. Importantly, during fear learning dominant vs subordinate others elicited stronger and more persistent learned threat responses as measured by physiological arousal and amygdala activity. Our results characterize the neural basis of learning through observing conflicts between others, and how this affects subsequent learning through direct, personal experiences. PMID:27217107

In addition to the type of mandatory health programme, the compensation required was also found to be dependent on a number of other factors. In particular, the study found an association between the compensation required and stronger libertarian preferences. DCEs can be used to measure the utility impact of a loss of consumer choice. Excluding the utility impact of a loss of consumer choice from an economic evaluation taking a societal perspective may result in a sub-optimal, or incorrect, funding decision.

Earlier functional imaging studies on the processing of vestibular information mainly focused on cortical activations due to stimulation of the horizontal semicircular canals in right-handers. Two factors were found to determine its processing in the temporo-parietal cortex: a dominance of the non-dominant hemisphere and an ipsilaterality of the neural pathways. In an investigation of the role of these factors in the vestibular otoliths, we used vestibular evoked myogenic potentials (VEMPs) in a fMRI study of monaural saccular-otolith stimulation. Our aim was to (1) analyze the hemispheric dominance for saccular-otolith information in healthy left-handers, (2) determine if there is a predominance of the ipsilateral saccular-otolith projection, and (3) evaluate the impact of both factors on the temporo-parieto-insular activation pattern. A block design with three stimulation and rest conditions was applied: (1) 102 dB-VEMP stimulation; (2) 65 dB-control-acoustic stimulation, (3) 102 dB-white-noise-control stimulation. After subtraction of acoustic side effects, bilateral activations were found in the posterior insula, the superior/middle/transverse temporal gyri, and the inferior parietal lobule. The distribution of the saccular-otolith activations was influenced by the two factors but with topographic disparity: whereas the inferior parts of the temporo-parietal cortex were mainly influenced by the ipsilaterality of the pathways, the upper parts reflected the dominance of the non-dominant hemisphere. This is in contrast to the processing of acoustic stimulation, which showed a predominance of the contralateral pathways. Our study proves the importance of the hemispheric preponderance also in left-handers, which is of relevance in the superior parts of the insula gyrus V, the inferior parietal lobule, and the superior temporal gyri.

Judging a man by the width of his face: the role of facial ratios and dominance in mate choice at speed-dating events.

PubMed

Valentine, Katherine A; Li, Norman P; Penke, Lars; Perrett, David I

Previous research has shown that men with higher facial width-to-height ratios (fWHRs) have higher testosterone and are more aggressive, more powerful, and more financially successful. We tested whether they are also more attractive to women in the ecologically valid mating context of speed dating. Men's fWHR was positively associated with their perceived dominance, likelihood of being chosen for a second date, and attractiveness to women for short-term, but not long-term, relationships. Perceived dominance (by itself and through physical attractiveness) mediated the relationship between fWHR and attractiveness to women for short-term relationships. Furthermore, men's perceptions of their own dominance showed patterns of association with mating desirability similar to those of fWHR. These results support the idea that fWHR is a physical marker of dominance. This is the first study to show that male dominance and higher fWHRs are attractive to women for short-term relationships in a controlled and interactive situation that could actually lead to mating and dating.

Aim To determine the factors affecting medical students’ choice of the specialty of family medicine. Methods The study was conducted in the period from 2004-2006 and comprised 770 first-year medical students from Ondokuz Mayis, Karadeniz Technical, Kocaeli, and Adnan Menderes Universities, Turkey. The questionnaire included questions on demographic data and 6 “yes/no” or open-ended questions on students’ career aspirations and the specialty of family medicine. Results The response rate was 93.1% (n = 717, 54.7% male). Nearly all students (n = 714, 99.6%) showed an intention to specialize after receiving the medical doctor degree. A total of 187 students (26.2%) showed an intention to work in primary care without specialization “for a temporary period” to “gain some experience.” Family medicine was the least preferred specialty (n = 7, 0.9%). The most important reasons for the choice of specialty were “better financial opportunities” and “prestige” (n = 219, 30.5%), followed by “personal development” (n = 149, 20.8%), “more benefits for the patient” (n = 128, 17.9%), and “wish to work in an urban area” (n = 32, 4.5%). The most preferred specialties were cardiology (n = 179, 25.0%), pediatrics (n = 121, 16.9%), ophthalmology (n = 47, 6.6%), physical therapy and rehabilitation (n = 34, 4.7%), and obstetrics and gynecology (n = 32, 4.5%). Conclusion Prestige, money, and personal development are important factors in career decision-making among medical students in Turkey. This should be taken into consideration when conducting reforms at the primary level. PMID:18581621

Factoring out nondecision time in choice reaction time data: Theory and implications.

PubMed

Verdonck, Stijn; Tuerlinckx, Francis

2016-03-01

Choice reaction time (RT) experiments are an invaluable tool in psychology and neuroscience. A common assumption is that the total choice response time is the sum of a decision and a nondecision part (time spent on perceptual and motor processes). While the decision part is typically modeled very carefully (commonly with diffusion models), a simple and ad hoc distribution (mostly uniform) is assumed for the nondecision component. Nevertheless, it has been shown that the misspecification of the nondecision time can severely distort the decision model parameter estimates. In this article, we propose an alternative approach to the estimation of choice RT models that elegantly bypasses the specification of the nondecision time distribution by means of an unconventional convolution of data and decision model distributions (hence called the D*M approach). Once the decision model parameters have been estimated, it is possible to compute a nonparametric estimate of the nondecision time distribution. The technique is tested on simulated data, and is shown to systematically remove traditional estimation bias related to misspecified nondecision time, even for a relatively small number of observations. The shape of the actual underlying nondecision time distribution can also be recovered. Next, the D*M approach is applied to a selection of existing diffusion model application articles. For all of these studies, substantial quantitative differences with the original analyses are found. For one study, these differences radically alter its final conclusions, underlining the importance of our approach. Additionally, we find that strongly right skewed nondecision time distributions are not at all uncommon. (c) 2016 APA, all rights reserved).

Large 21-cm signals from AGN-dominated reionization

We present predictions for the spatial distribution of 21-cm brightness temperature fluctuations from high-dynamic-range simulations for active galactic nucleus (AGN)-dominated reionization histories that have been tested against available Lyα and cosmic microwave background (CMB) data. We model AGNs by extrapolating the observed Mbh - σ relation to high redshifts and assign them ionizing emissivities consistent with recent UV luminosity function measurements. We assess the observability of the predicted spatial 21-cm fluctuations in the late stages of reionization in the limit in which the hydrogen 21-cm spin temperature is significantly larger than the CMB temperature. Our AGN-dominated reionization histories increase the variance of the 21-cm emission by a factor of up to 10 compared to similar reionization histories dominated by faint galaxies, to values close to 100 mK2 at scales accessible to experiments (k ≲ 1 cMpc-1 h). This is lower than the sensitivity reached by ongoing experiments only by a factor of about 2 or less. When reionization is dominated by AGNs, the 21-cm power spectrum is enhanced on all scales due to the enhanced bias of the clustering of the more massive haloes and the peak in the large scale 21-cm power is strongly enhanced and moved to larger scales due to bigger characteristic bubble sizes. AGN-dominated reionization should be easily detectable by Low Frequency Array (and later Hydrogen Epoch of Reionization Array and Phase 1 of the Square Kilometre Array) at their design sensitivity, assuming successful foreground subtraction and instrument calibration. Conversely, these could become the first non-trivial reionization scenarios to be ruled out by 21-cm experiments, thereby constraining the contribution of AGNs to reionization.

A choice mind-set increases the acceptance and maintenance of wealth inequality.

Wealth inequality has significant psychological, physiological, societal, and economic costs. In six experiments, we investigated how seemingly innocuous, culturally pervasive ideas can help maintain and further wealth inequality. Specifically, we tested whether the concept of choice, which is deeply valued in American society, leads Americans to act in ways that perpetuate wealth inequality. Thinking in terms of choice, we argue, activates the belief that life outcomes stem from personal agency, not societal factors, and thereby leads people to justify wealth inequality. The results showed that highlighting the concept of choice makes people less disturbed by facts about existing wealth inequality in the United States, more likely to underestimate the role of societal factors in individuals' successes, less likely to support the redistribution of educational resources, and less likely to support raising taxes on the rich-even if doing so would help resolve a budget deficit crisis. These findings indicate that the culturally valued concept of choice contributes to the maintenance of wealth inequality.

Introduction Nowadays, an important decision for pregnant women is whether to undergo prenatal testing for aneuploidies and which tests to uptake. We investigate the factors influencing women’s choices between non-invasive prenatal testing (NIPT) and invasive prenatal tests in pregnancies with elevated a priori risk of fetal aneuploidies. Methodology This is a mixed-method study. We used medical data (1st Jan 2015-31st Dec 2015) about women participating in further testing at Fetomaternal Medical Center at Helsinki University Hospital and employed Chi-square tests and ANOVA to compare the groups of women choosing different methods. Multinomial logistic regressions revealed the significant clinical factors influencing women’s choice. We explored the underlying values, beliefs, attitudes and other psychosocial factors that affect women’s choice by interviewing women with the Theory of Planned Behavior framework. The semi-structured interview data were processed by thematic analysis. Results Statistical data indicated that gestational age and counseling day were strong factors influencing women’s choice. Interview data revealed that women’s values and moral principles on pregnancy and childbirth chiefly determined the choices. Behavioral beliefs (e.g. safety and accuracy) and perceived choice control (e.g. easiness, rapidness and convenience) were also important and the major trade-offs happened between these constructs. Discussion Values are the determinants of women’s choice. Service availability and convenience are strong factors. Medical risk status in this choice context is not highly influential. Choice aids can be developed by helping women to identify their leading values in prenatal testing and by providing lists of value-matching test options and attributes. PMID:28355226

Reward Contrast Effects on Impulsive Choice and Timing in Rats

Despite considerable interest in impulsive choice as a predictor of a variety of maladaptive behaviors, the mechanisms that drive choice behavior are still poorly understood. The present study sought to examine the influence of one understudied variable, reward magnitude contrast, on choice and timing behavior as changes in magnitude commonly occur within choice procedures. In addition, assessments of indirect effects on choice behavior through magnitude-timing interactions were assessed by measuring timing within the choice task. Rats were exposed to choice procedures composed of different pairs of magnitudes of rewards for either the smaller-sooner (SS) or larger-later (LL) option. In Phase 2, the magnitude of reward either increased or decreased by 1 pellet in different groups (LL increase = 1v1→1v2; SS decrease = 2v2 → 1v2; SS increase = 1v2 → 2v2), followed by a return to baseline in Phase 3. Choice behavior was affected by the initial magnitudes experienced in the task, demonstrating a strong anchor effect. The nature of the change in magnitude affected choice behavior as well. Timing behavior was also affected by the reward contrast manipulation albeit to a lesser degree and the timing and choice effects were correlated. The results suggest that models of choice behavior should incorporate reinforcement history, reward contrast elements, and magnitude-timing interactions, but that direct effects of reward contrast on choice should be given more weight than the indirect reward-timing interactions. A better understanding of the factors that contribute to choice behavior could supply key insights into this important individual differences variable. PMID:27867839

Are vent crab behavioral preferences adaptations for habitat choice?

Hydrothermal vent organisms are adapted to their extreme and patchily distributed habitats. They are expected to have evolved mechanisms that keep them in their specific habitation. Since little is known about the recruitment or habitat selection of HV organisms such as brachyurans, we examined the properties of several hydrothermal vent-associated cues on the behavior of the hydrothermal vent (HV) crab Xenograpsus testudinatus in the laboratory that were contrasted by the offering of non-vent cues. This crab species is endemic and dominates the vent fauna of Turtle Island off the NE coast of Taiwan. HV crabs were separately and in combination offered the following vent-specific cues: (1) sulfuric sediment, (3) air-bubbling, (4) elevated temperature, (5) dead settled zooplankton, (7) other crabs, and (8) shade. The non-vent-specific cues were: (2) quarz sediment, (6) dead fish, (8) light. These cues were provided on either side of a two-choice chamber. The movement of individual crabs was monitored: as initial and final choices, and as the proportion of time the crabs spent in each compartment (resident time). Cues were offered alone and no such cue as a control in the same set-up. Sulfuric sediments and dead fish were significantly more attractive to females, and other crabs irrespective of gender were significantly more attractive to males. When compared to expected distributions, crabs, irrespective of gender, significantly avoided light and tended to select other crabs, air-bubbling, sulfuric sediment, elevated temperature, dead fish, dead zooplankton, and quarz sediments in the order of decreasing importance. Data do not support the hypothesis that dead settled zooplankton was particularly attractive nor that the other gender was selected. A combination of several vent-associated cues (sulfuric sediment, elevated temperature, air-bubbling) facilitated the strongest attraction to the crabs as reflected by all response variables.

Contextual and social influences on valuation and choice.

PubMed

Engelmann, Jan B; Hein, Grit

2013-01-01

To survive in our complex environment, we have to adapt to changing contexts. Prior research that investigated how contextual changes are processed in the human brain has demonstrated important modulatory influences on multiple cognitive processes underlying decision-making, including perceptual judgments, working memory, as well as cognitive and attentional control. However, in everyday life, the importance of context is even more obvious during economic and social interactions, which often have implicit rule sets that need to be recognized by a decision-maker. Here, we review recent evidence from an increasing number of studies in the fields of Neuroeconomics and Social Neuroscience that investigate the neurobiological basis of contextual effects on valuation and social choice. Contrary to the assumptions of rational choice theory, multiple contextual factors, such as the availability of alternative choice options, shifts in reference point, and social context, have been shown to modulate behavior, as well as signals in task-relevant neural networks. A consistent picture that emerges from neurobiological results is that valuation-related activity in striatum and ventromedial prefrontal cortex is highly context dependent during both social and nonsocial choice. Alternative approaches to model and explain choice behavior, such as comparison-based choice models, as well as implications for future research are discussed. Copyright © 2013 Elsevier B.V.

2008-05-01

The aims of the present work were to study motives underlying Uruguayan consumers' food choice behaviour and to study the consumption frequency of some selected food items. A modification of the Food Choice Questionnaire and a food frequency questionnaire was administered to a group of 200 Uruguayan consumers. Feeling good and safety, sensory appeal and health and nutrient content were rated as the most important factors, while familiarity was rated as the least important. Using hierarchical cluster analysis, three clusters with different choice patterns were identified. Frequency of consumption of fruits, vegetables, milk and dairy products, and whole cereals, increased as the importance attributed to health and nutrition increased; consumption of fatty foods decreased.

Trace Elements in Dominant Species of the Fenghe River, China: Their Relations to Environmental Factors.

The distribution of trace elements (TEs) in water, sediment, riparian soil and dominant plants was investigated in the Fenghe River, Northwestern China. The Fenghe River ecosystem was polluted with Cd, Cr, Hg and Pb. There was a high pollution risk in the midstream and downstream regions and the risk level for Cd was much higher than that of the other elements. The average values of bioconcentration coefficient for Cd and Zn were 2.21 and 1.75, respectively, indicating a large accumulation of Cd and Zn in the studied species. With broad ecological amplitudes, L. Levl. et Vant. Trin., and L. had the greatest TE concentrations in aboveground and belowground biomass of the studied species and were potential biomonitors or phytoremediators for the study area. Multivariate techniques including cluster analysis, correlation analysis, principal component analysis, and canonical correspondence analysis were used to analyze the relations between TE concentrations in plants and various environmental factors. The soil element concentration is the main factor determining the accumulation of TEs in plants. The co-release behavior of common pollutants and TEs drove the accumulation of Hg, Cd, and As in the studied plants. Significant enrichment of some elements in the Fenghe River has led to a decline in the biodiversity of plants.

Understanding preferences for specialties by medical students and the factors driving choices assists policy makers in ensuring optimal spread of personnel across disciplines. This cross-sectional survey using self-administered structured questionnaires was conducted on consenting students of the first medical school in The Gambia, established in 1999. Data collection was in June/July 2011. Questions were on sociodemographic characteristics of students, their parents, factors related to career preferences and opinions about counseling services. Data were analysed using JMP 8.0 software. Respondents were 52.4% of 202 eligible students. Mean age was 24.1 ± 5.0 years. Females constituted 54.7%. Muslims were 72.7% while Gambians formed 77.0%. Commonest specialties chosen by females were Obstetrics/Gynaecology, Paediatrics and Surgery in that order, while males preferred Internal Medicine, Surgery and Obstetrics/Gynaecology. Commonest factors influencing choices by females were 'focus on urgent care' (65.5%) and 'intellectual content of specialty' (56.9%). For males, these were 'intellectual content of specialty' (60.4%) and 'focus on urgent care' / 'individual's competence' (50.0% each). More females (30.0%) than males (23.0%) had ever received career counseling, but all students desired it. Significant gender differences exist in specialty choices and factors influencing these choices amongst these students. All want career counseling.

2018-01-01

In a queueing system involving multiple service windows, choice behavior is a significant concern. This paper incorporates the choice of service windows into a queueing model with a floor represented by discrete cells. We contrived a logit-based choice algorithm for agents considering the numbers of agents and the distances to all service windows. Simulations were conducted with various parameters of agent choice preference for these two elements and for different floor configurations, including the floor length and the number of service windows. We investigated the model from the viewpoint of transit times and entrance block rates. The influences of the parameters on these factors were surveyed in detail and we determined that there are optimum floor lengths that minimize the transit times. In addition, we observed that the transit times were determined almost entirely by the entrance block rates. The results of the presented model are relevant to understanding queueing systems including the choice of service windows and can be employed to optimize facility design and floor management.

The aim of this paper is to study home care clients' freedom to choose their services, as well the association between the effectiveness of home care services and freedom of choice, among other factors. A structured postal survey was conducted among regular home care clients (n = 2096) aged 65 or older in three towns in Finland. Freedom of choice was studied based on clients' subjective experiences. The effectiveness of the services was evaluated by means of changes in the social-care-related quality of life. Regression analyses were used to test associations. As much as 62% of home care recipients reported having some choice regarding their services. Choosing meals and visiting times for the care worker were associated with better effectiveness. The basic model, which included needs and other factors expected to have an impact on quality of life, explained 15.4% of the changes in quality of life, while the extended model, which included the freedom-of-choice variables, explained 17.4%. The inclusion of freedom-of-choice variables increased the adjusted coefficient of determination by 2%. There was a significant positive association between freedom of choice and the effectiveness of public home care services. Freedom of choice does not exist for all clients of home care who desire it. By changing social welfare activities and structures, it is possible to show respect for clients' opinions and to thereby improve the effectiveness of home care services.

The coculture of cells expressing the HIV-1 envelope glycoprotein complex (Env) with cells expressing CD4 results into cell fusion, deregulated mitosis, and subsequent cell death. Here, we show that NF-kappaB, p53, and AP1 are activated in Env-elicited apoptosis. The nuclear factor kappaB (NF-kappaB) super repressor had an antimitotic and antiapoptotic effect and prevented the Env-elicited phosphorylation of p53 on serine 15 and 46, as well as the activation of AP1. Transfection with dominant-negative p53 abolished apoptosis and AP1 activation. Signs of NF-kappaB and p53 activation were also detected in lymph node biopsies from HIV-1-infected individuals. Microarrays revealed that most (85%) of the transcriptional effects of HIV-1 Env were blocked by the p53 inhibitor pifithrin-alpha. Macroarrays led to the identification of several Env-elicited, p53-dependent proapoptotic transcripts, in particular Puma, a proapoptotic "BH3-only" protein from the Bcl-2 family known to activate Bax/Bak. Down modulation of Puma by antisense oligonucleotides, as well as RNA interference of Bax and Bak, prevented Env-induced apoptosis. HIV-1-infected primary lymphoblasts up-regulated Puma in vitro. Moreover, circulating CD4+ lymphocytes from untreated, HIV-1-infected donors contained enhanced amounts of Puma protein, and these elevated Puma levels dropped upon antiretroviral therapy. Altogether, these data indicate that NF-kappaB and p53 cooperate as the dominant proapoptotic transcription factors participating in HIV-1 infection.

Different reasons for one significant choice: Factors influencing homeschooling choice in Israel

Guterman, Oz; Neuman, Ari

2017-06-01

Homeschooling is an alternative to conventional education in many countries all over the world, though legal regulations vary. This article examines why parents opt for homeschooling. The large body of research on the topic (especially from the United States) points to a variety of reasons for making the choice to homeschool. The most common reasons are of a pedagogical nature, but in many cases they are also family-related. What has not yet been investigated in depth is the relationship between the different reasons for choosing homeschooling and the way in which homeschooling is practised. There is also a lack of research on the relationship between the reasons for choosing homeschooling and the parents' personalities, educational background and attitudes towards both homeschooling in particular and the education system in general. Using a mixed methods design in order to examine these relationships, the authors of this article questioned 62 homeschooling families in Israel. The findings indicate that some parents chose to homeschool for pedagogical reasons only and others for both pedagogical and family-related reasons. Furthermore, the latter group held more positive views of the effect of homeschooling on children - and the mothers in that group, on average, were more educated compared with those who cited pedagogical reasons alone. The reasons for choosing homeschooling were also found to be associated with the character of the homeschooling practice, with families whose reasons were pedagogical only devoting more hours, on average, specifically to studying.

EGMs are a form of entertainment, and the gambling environment is an important contributor to the overall experience. Logically, to select a play-environment, EGM gamblers must choose the platform through which to access the EGM (e.g., internet, mobile application or land-based venue), a particular provider (e.g., specific website, app vendor or branded casino), and the game itself (e.g., based on graphical theme or bonus features; Thorne et al. in J Gambl Stud, 2016. doi: 10.1007/s10899-016-9601-2 ). A discrete choice experiment was conducted to identify the features of the platform, provider and game that are most strongly preferred by EGM gamblers. Participants were 245 EGM gamblers from clubs in Victoria, Australia and 7516 EGM gamblers from an Australian online panel. Results indicate that the ideal environment for the average gambler consists of: gambling at a club that is close to home; with a group of friends; in a relatively quiet place that has air conditioning, cheap food and a large space to play in; on a classic game with quality animations and small bet sizes; where you feel safe and secure; and where there is a wide variety of other games to play when you are done. Segmenting these results by problem-gambler status highlights important differences in preferences between problem and non-problem gamblers. Problem gamblers are less likely to give weight to the company they share and have a preference for larger venues. Using a powerful paradigm from marketing research, the present study was able to determine the relative value of different features of the EGM gambling environment, and also contributes important insight towards what constitutes a safer environment for recreational play.

Cyanobacterial blooms in freshwaters have become one of the most widespread of environmental problems and threaten water resources worldwide. Previous studies on cyanobacteria in Lake Taihu often collected samples from one site (like Meiliang Bay or Zhushan Bay) and focused on the variation in patterns or abundance of Microcystis during the blooming season. However, the distribution of cyanobacteria in Lake Taihu shows differing pattern in various seasons. In this study, water samples were collected monthly for one year at five sites in Lake Taihu with different trophic status and a physicochemical analysis and denaturing gradient gel electrophoresis (DGGE) were conducted. DGGE fingerprint analysis showed that Microcystis (7/35 bands) and Synechococcus (12/35 bands) were the two most dominant genera present during the study period at all five sites. Cyanobium (3/35 bands) was the third most common genus which has seldom been previously reported in Lake Taihu. Redundancy analysis (RDA) indicated that the cyanobacterial community structure was significantly correlated with NO3 (-)-N, CODMn, and NH4 (+)-N in the winter and spring, whereas it was correlated with water temperature in the summer and autumn. Limiting the nutrient input (especially of N and C loading) in Lake Taihu would be a key factor in controlling the growth of different genera of cyanobacteria.

Factors that influence reinforcer choice have been examined in a number of applied studies (e.g., Neef, Mace, Shea, & Shade, 1992; Shore, Iwata, DeLeon, Kahng, & Smith, 1997; Tustin, 1994). However, no applied studies have evaluated the effects of postsession reinforcement on choice between concurrently available reinforcers, even though basic findings indicate that this is an important factor to consider (Hursh, 1978; Zeiler, 1999). In this bridge investigation, we evaluated the influence of postsession reinforcement on choice of two food items when task responding was reinforced on progressive-ratio schedules. Participants were 3 children who had been diagnosed with developmental disabilities. Results indicated that response allocation shifted from one food item to the other food item under thinner schedules of reinforcement when no postsession reinforcement was provided. These findings suggest that the efficacy of instructional programs or treatments for problem behavior may be improved by restricting reinforcers outside treatment sessions. PMID:17970264
