    A postal survey of typeface preference is described. The survey was designed to help in the choice of typeface to be used for the internal technical Reports produced by the Post Office Research Department. Type setting for these Reports is carried out using an IBM Selectric Composer for which seven typefaces suitable for reports are available. One hundred and twenty-five people who regularly receive copies of these Reports and 57 Trainee Technicians (Apprentices) were asked to arrange these seven typefaces in order of preference and record this ranking on a response sheet. About 85% of both groups returned response sheets for statistical analysis. The results showed a significant preference for three of the typefaces: Press Roman, Theme and Univers. Of these, Press Roman is used for the text of Research Department Reports and Univers is used on diagrams and tables.

    Capital derived from immoral sources is increasingly circulated in today’s financial markets. The moral associations of capital are important, although their impact on investment remains unknown. This research aims to explore the influence of principal source morality on investors’ risk preferences. Three studies were conducted in this regard. Study 1 finds that investors are more risk-seeking when their principal is earned immorally (through lying), whereas their risk preferences do not change when they invest money earned from neutral sources after engaging in immoral behavior. Study 2 reveals that guilt fully mediates the relationship between principal source morality and investors’ risk preferences. Studies 3a and 3b introduce a new immoral principal source and a new manipulation method to improve external validity. Guilt is shown to the decrease the subjective value of morally flawed principal, leading to higher risk preference. The findings show the influence of morality-related features of principal on people’s investment behavior and further support mental account theory. The results also predict the potential threats of “grey principal” to market stability. PMID:28369117

    We investigated whether implicit learning in a visual search task would influence preferences for visual stimuli. Participants performed a contextual cueing task in which they searched for visual targets, the locations of which were either predicted or not predicted by the positioning of distractors. The speed with which participants located the targets increased across trials more rapidly for predictive displays than for non-predictive displays, consistent with contextual cueing. Participants were subsequently asked to rate the "goodness" of visual displays. The rating results showed that they preferred predictive displays to both non-predictive and novel displays. The participants did not recognize predictive displays any more frequently than they did non-predictive or novel displays. These results suggest that contextual cueing occurred implicitly and that the implicit learning of visual layouts promotes a preference for visual layouts that are predictive of target location.

    Previous studies from our laboratory found that rats express increased preference for drug-paired stimuli following 2 or 5 weeks of protracted abstinence from chronic drug exposure as compared with naive animals. Here, we show that this increased morphine place preference depends upon experiencing drug-stimulus pairings specifically in the abstinent state, indicating a critical role for incentive learning. Male Sprague Dawley rats were initially conditioned for morphine place preference (8 mg/kg) and then made dependent on morphine (by subcutaneous morphine pellets) and subjected to forced abstinence. Place preference was tested every 1-2 weeks with no additional drug-cue conditioning. In this paradigm, there was no difference between morphine-pelleted (dependent) and placebo-pelleted (non-dependent) rats in place preference at any time during abstinence (up to 6 weeks). However, these same morphine-pelleted rats expressed significantly increased preference when they were subsequently re-conditioned for morphine place preference during protracted abstinence. Placebo-pelleted rats did not show enhanced preference after re-conditioning. These findings reveal that incentive learning has a key role in increased morphine place preference when drug is experienced during protracted abstinence. This indicates that incentive learning is involved not only in instrumental responding (as previously reported), but also in updating Pavlovian-conditioned responses to morphine-associated stimuli. Therefore, enhanced morphine preference is not a direct consequence of the negative affective state of abstinence, but instead reflects increased acquisition of morphine-stimulus associations during abstinence. These results indicate that, during the development of addiction in humans, drug-associated stimuli acquire increasingly stronger incentive properties each time they are re-experienced.

    Full Text Available Gene expression is closely related to optimal vector-host system pairing in many prokaryotes. Redesign of the human cystatin C (cysC gene using the preferred codons of the prokaryotic system may significantly increase cysC expression in Escherichia coli (E. coli. Specifically, cysC expression may be increased by removing unstable sequences and optimizing GC content. According to E. coli expression system codon preferences, the gene sequence was optimized while the amino acid sequence was maintained. The codon-optimized cysC (co-cysC and wild-type cysC (wt-cysC were expressed by cloning the genes into a pET-30a plasmid, thus transforming the recombinant plasmid into E. coli BL21. Before and after the optimization process, the prokaryotic expression vector and host bacteria were examined for protein expression and biological activation of CysC. The recombinant proteins in the lysate of the transformed bacteria were purified using Ni2+-NTA resin. Recombinant protein expression increased from 10% to 46% based on total protein expression after codon optimization. Recombinant CysC purity was above 95%. The significant increase in cysC expression in E. coli expression produced by codon optimization techniques may be applicable to commercial production systems.

    'Mapping' onto generic preference-based outcome measures is increasingly being used as a means of generating health utilities for use within health economic evaluations. Despite publication of technical guides for the conduct of mapping research, guidance for the reporting of mapping studies is currently lacking. The MAPS (MApping onto Preference-based measures reporting Standards) statement is a new checklist, which aims to promote complete and transparent reporting of mapping studies. The primary audiences for the MAPS statement are researchers reporting mapping studies, the funders of the research, and peer reviewers and editors involved in assessing mapping studies for publication.A de novo list of 29 candidate reporting items and accompanying explanations was created by a working group comprised of six health economists and one Delphi methodologist. Following a two-round, modified Delphi survey with representatives from academia, consultancy, health technology assessment agencies and the biomedical journal editorial community, a final set of 23 items deemed essential for transparent reporting, and accompanying explanations, was developed. The items are contained in a user friendly 23 item checklist. They are presented numerically and categorised within six sections, namely: (i) title and abstract; (ii) introduction; (iii) methods; (iv) results; (v) discussion; and (vi) other. The MAPS statement is best applied in conjunction with the accompanying MAPS explanation and elaboration document.It is anticipated that the MAPS statement will improve the clarity, transparency and completeness of reporting of mapping studies. To facilitate dissemination and uptake, the MAPS statement is being co-published by eight health economics and quality of life journals, and broader endorsement is encouraged. The MAPS working group plans to assess the need for an update of the reporting checklist in five years' time.This statement was published jointly in Applied Health Economics

    Our aim was to determine if levels of television viewing (a proxy measure for habitual commercial exposure) affect children's food preference responses to television food commercials. A total of 281 children aged 6 to 13 years from northwest England viewed toy or food television commercials followed by a cartoon on 2 separate occasions; they then completed 3 food preference measures, a commercial recognition task, and a television viewing questionnaire. After viewing the food commercials, all children selected more branded and nonbranded fat-rich and carbohydrate-rich items from food preference checklists compared with after viewing the toy commercials. The food preferences of children with higher habitual levels of television viewing were more affected by food commercial exposure than those of low television viewers. After viewing food commercials, high television viewing children selected a greater number of branded food items compared with after the toy commercials as well as compared with the low television viewers. Children correctly recognized more food commercials than toy commercials. Exposure to television food commercials enhanced high television viewers' preferences for branded foods and increased reported preferences for all food items (branded and nonbranded) relative to the low television viewers. This is the first study to demonstrate that children with greater previous exposure to commercials (high television viewers) seemed to be more responsive to food promotion messages than children with lower previous advertising exposure.

    One form of paired preference test protocol requires consumers to assess 2 pairs of products. One is the target pair under consideration, while the other is a putatively identical pair named the "placebo pair" which is also presented as a control. Counterintuitively, the majority of consumers report preferences when presented with the placebo pair. Their response frequencies are hypothesized to be those of consumers having "no preference" and are compared with the response frequencies elicited by a target pair, to determine whether the target pair elicits significant preferences. The primary goal of this paper was to study the robustness of 2 new so called disruptive protocols that reduced the proportion of consumers, who reported preferences when assessing a putatively identical pair of products. For this task, the tests were performed in a different language, in a different country, using different products from before. The results showed that the proportion of consumers reporting preferences for the placebo pair was reduced, confirming earlier work. Also, comparison of d' values showed a lack of significant overall differences between the placebo and target pairs, while chi-squared analyses indicated significant differences in the response frequencies. This indicated that the sample was segmented into 2 balanced groups with opposing preferences.

    To determine referring physicians' general attitudes, preferred reporting types, and opinions on radiologic reports. A survey questionnaire was distributed to the 315 staff and residents of four university hospitals with 400 to 800 beds, and a total of 228 physicians responded. The questionnaire aimed to determine of the general attitude of referring physicians to radiologic reports, the type of report they preferred, and other opinions and suggestions. The responses elicited, as well as discrepancies among residents, staff, internist, and surgeons, were analyzed. Most referring physicians replied that they read an entire report regardless of its length, and the second majority read the conclusion first and then the remainder of the report only if clarification was required. With regard to report length, physicians answered that reports describing the findings of conventional radiography were often too short, while those dealing with MRI were verbose. The majority experienced occasional confusion when reading a report, the major cause being grammatical errors and incomprehensible sentence structure. When confused, most physicians consulted the radiologist ; staff showed a greater inclination than residents to pursue this option. Most physicians preferred brief phrases or telegraphic-style sentences to a style which stressed completeness and detail, a preference which was statistically higher among residents than staff. Whereas physicians favored a brief radiologic report in cases of normal radiologic findings, conventional radiologic studies or no clinical findings, they wished to see a more detailed report in cases of abnormal radiologic findings, specific radiologic studies (special radiographs, US, CT, or MRI), or positive clinical findings. This need for more detail was expressed more frequently by internists than by surgeons. If implemented, the results of this study can be expected to enhance the quality and comprehensibility of radiologic reports, and

  10. Human infants' preference for left-to-right oriented increasing numerical sequences.

    Full Text Available While associations between number and space, in the form of a spatially oriented numerical representation, have been extensively reported in human adults, the origins of this phenomenon are still poorly understood. The commonly accepted view is that this number-space association is a product of human invention, with accounts proposing that culture, symbolic knowledge, and mathematics education are at the roots of this phenomenon. Here we show that preverbal infants aged 7 months, who lack symbolic knowledge and mathematics education, show a preference for increasing magnitude displayed in a left-to-right spatial orientation. Infants habituated to left-to-right oriented increasing or decreasing numerical sequences showed an overall higher looking time to new left-to-right oriented increasing numerical sequences at test (Experiment 1. This pattern did not hold when infants were presented with the same ordinal numerical information displayed from right to left (Experiment 2. The different pattern of results was congruent with the presence of a malleable, context-dependent baseline preference for increasing, left-to-right oriented, numerosities (Experiment 3. These findings are suggestive of an early predisposition in humans to link numerical order with a left-to-right spatial orientation, which precedes the acquisition of symbolic abilities, mathematics education, and the acquisition of reading and writing skills.

    Self-care preferences can be used in designing programs of care. Yet little has been documented concerning the self-care habits and preferences of older adults. This study assessed the reliability of reports of self-care preferences and their importance among older adults using the Self-maintenance Habits and Preferences in Elderly (SHAPE) instrument. Twenty community-dwelling seniors completed the SHAPE questionnaire twice within a one- to two-week interval. Percent agreement, both exact and close/partial, was computed to assess the reliability of preference content, and intra-class correlations (ICCs) were used for preference importance. Test and subject factors affecting reliability were also investigated. Exact agreement rate for item content was 73%, and that for close/partial agreement was 93%. Mean ICC for item importance was 0.72. Reliability was greater for dichotomous items than for either ordinal or categorical questions. Reliability of item content varied with number of response options and importance reliability varied with age and IADL status. Information from SHAPE about self-care preferences can be used to plan services for seniors and to individualize care for older persons, especially those transitioning to new living environments or those receiving home care.

    Aim: To determine hospital consultants' preferences for the format and content of radiology reports. Materials and methods: Ninety-nine questionnaires were sent to consultant staff with responsibility for requesting ultrasound examinations. The participants were invited to rank a variety of hypothetical reports in order of preference. They were also asked whether they felt other commonly included features of a radiology report were of value. Rank data were analysed by the Friedman statistic, Fisher's multiple comparisons least significant difference test, and the Kemeny-Young method. Results: Forty-nine responses were received. There was a preference for more detailed reports that included a clinical comment by the radiologist, for both normal and abnormal results (p < 0.05). Reports presented in tables were preferred. The combination of a detailed tabular report with a radiologist's comment was the most popular single structure, preferred by 43% of respondents for normal reports and 51% for abnormal reports. Conclusion: Detailed reports with a radiologists' comment are preferred to briefer reports, even for normal examinations. Tabular reports are preferred to prose, with the combination of a detailed report presented in a tabular format accompanied by a radiologist's comment being the most preferred style.

    The results of this study provide information that might be used to develop an approach to weight loss management for individuals with Prader-Willi syndrome that emphasizes the increase of output. Specifically, our finding that they do have a definite food preference and, subsequently, that they prefer a lesser amount of the high-preference food than a greater amount of low-preference food is contradictory to several non-empirical reports (Holm, 1981; Pipes & Holm, 1981). Further, the use of food as a reinforcer has been considered taboo by those who use more conventional and restrictive management approaches with Prader-Willi syndrome individuals. Our data, however, strongly suggest that a low volume of food can be used as an effective reinforcer for increased activity and exercise.

    Buprenorphine (BPN) is widely used as a substitution treatment for opioid addiction. Some cases of abuse and misuse, especially associated with various benzodiazepines (BZDs), have been described, and a previous study has shown that BZDs increase the sedative effect of BPN and decrease its anxiogenic properties. To investigate the reward effect that may lead to the abusive combination of BPN and BZD, we studied the influence of different doses of three BZDs extensively used with BPN by drug addicts on conditioned place preference behavior in mice. BPN (0.3, 1, 3 mg/kg) was injected subcutaneously into male mice alone or in combination with a BZD administered intraperitoneally: dipotassium clorazepate (CRZ; 1, 4, 16 mg/kg), diazepam (DAZ; 0.5, 1, 5 mg/kg), or bromazepam (BMZ; 0.5, 1, 3 mg/kg). Amphetamine (8 mg/kg) was used as a reference drug. Reward effects of BPN alone or in combination were measured in a conditioned place preference paradigm using an unbiased procedure. Our results showed that groups treated with BPN associated with different doses of diazepam and clorazepate, but not bromazepam, spent significantly more time in the drug-paired compartment compared to the group treated with BPN alone. Our study shows that joint consumption of diazepam and clorazepate, but not bromazepam, can increase the reward properties of BPN alone in mice. These results could help to explain the use of this type of drug combination in the drug addict population. © 2014 Société Française de Pharmacologie et de Thérapeutique.

Such preference has been found in reports of body weight, cigarette consumption or blood pressure measurements. Very little is known about self-reported body height. End-digit preference can distort estimates of prevalence and other statistical parameters. This study examines end-digit preference for self-reported height and how it relates with sex, age, educational level or cultural affiliation. We analysed reports of height of 47,192 individuals (aged 15 years or older) living in Switzerland and participating in one of the three population-based Swiss Health Surveys carried out in 1992/93, 1997 and 2002 respectively. Digit preferences were analysed by sex, age group, educational level, survey, smoking status, interview language (only for Swiss nationals) and nationality. Adjusted odds ratios (OR) with 95% confidence interval were calculated by using multivariate logistic regression. Italian and French nationals (44.1% and 40.6%) and Italian and French Swiss (39.6% and 35.3%) more strongly preferred zero and five than Germans and German Swiss (29.2% and 30.3%). Two, four, six and eight were more popular in Germans and German Swiss (both 44.4%). Compared to German Swiss (OR = 1), for the end-digits zero and five, the OR were 1.50 (1.38-1.63) for Italian Swiss and 1.24 (1.18-1.30) for French Swiss; 1.73 (1.58-1.89) for Italian nationals and 1.61 (1.33-1.95) for French nationals. The end-digits two, four, six and eight showed an opposite pattern. Different preferences for end-digits depending on language and nationality could be observed consistently in all three national health surveys. The patterns were strikingly similar in Swiss and foreign nationals speaking the same language, suggesting that preferences were specific to language rather than to nationality. Taking into account rounding preferences could allow more valid comparisons in analyses of self-reported data

    When rodents are given a free choice between a variable option and a constant option, they may prefer variability. This preference is even sometimes increased following repeated administration of a dopamine agonist. The present study was the first to examine preference for variability under the systemic administration of a dopamine agonist, apomorphine (Apo), in birds. Experiment 1 tested the drug-free preference and the propensity to choose of pigeons for a constant over a variable delay. It appeared that they preferred and decided more quickly to peck at the optimal delay option. Experiment 2 assessed the effects of a repeated injection of Apo on delay preference, in comparison with previous control tests within the same individuals. Apo treatment might have decreased the number of pecks at the constant option across the different experimental phases, but failed to induce a preference for the variable option. In Experiment 3, two groups of pigeons (Apo-sensitized and saline) were used in order to avoid inhomogeneity in treatments. They had to choose between a 50% probability option and a 5-s delay option. Conditioned pecking and the propensity to choose were higher in the Apo-sensitized pigeons, but, in each group, the pigeons showed indifference between the two options. This experiment also showed that long-term behavioral sensitization to Apo can occur independently of a conditioning process. These results suggest that Apo sensitization can enhance the attractiveness of conditioned cues, while having no effect on the development of a preference for variable-delay and probabilistic schedules of reinforcement.

    The Miocene radiation of C4 grasses under high-temperature and low ambient CO 2 levels occurred alongside the transformation of a largely forested landscape into savanna. This inevitably changed the host plant regime of herbivores, and the simultaneous diversification of many consumer lineages, including Bicyclus butterflies in Africa, suggests that the radiations of grasses and grazers may be evolutionary linked. We examined mechanisms for this plant-herbivore interaction with the grass-feeding Bicyclus safitza in South Africa. In a controlled environment, we tested oviposition preference and hatchling performance on local grasses with C3 or C4 photosynthetic pathways that grow either in open or shaded habitats. We predicted preference for C3 plants due to a hypothesized lower processing cost and higher palatability to herbivores. In contrast, we found that females preferred C4 shade grasses rather than either C4 grasses from open habitats or C3 grasses. The oviposition preference broadly followed hatchling performance, although hatchling survival was equally good on C4 or C3 shade grasses. This finding was explained by leaf toughness; shade grasses were softer than grasses from open habitats. Field monitoring revealed a preference of adults for shaded habitats, and stable isotope analysis of field-sampled individuals confirmed their preference for C4 grasses as host plants. Our findings suggest that plant-herbivore interactions can influence the direction of selection in a grass-feeding butterfly. Based on this work, we postulate future research to test whether these interactions more generally contribute to radiations in herbivorous insects via expansions into new, unexploited ecological niches.

    Recent studies investigating the relationship between self-reported sexual desire and attraction to same- and opposite-sex individuals have found that homosexual men's sexual desire is positively correlated with their self-reported attraction to own-sex individuals only, while homosexual women's sexual desire is positively correlated with their self-reported attraction to both men and women. These data have been interpreted as evidence that sexual desire strengthens men's pre-existing (i.e., dominant) sexual behaviors and strengthens women's sexual behaviors in general. Here we show that homosexual men's (n = 106) scores on the Sexual Desire Inventory-2 (SDI-2) were positively correlated with their preferences for exaggerated sex-typical shape cues in own-sex, but not opposite-sex, faces. Contrary to the hypothesis that sexual desire strengthens women's preferences for sexual dimorphism generally, homosexual women's (n = 83) SDI-2 scores were positively correlated with their preferences for exaggerated sex-typical shape cues in opposite-sex faces only. Together with previous research in heterosexual subjects, our findings support the proposal that sexual desire increases the incidence of existing sexual behaviors in homosexual and heterosexual men, and increases the incidence of sexual responses more generally in heterosexual women, although not necessarily in homosexual women.

    From the perspective of terror management theory, reminders of mortality should intensify the desire to pursue cognitive consistency. The authors investigated this notion with regard to dissonance theory starting from the finding of research on "selective exposure to information" that after having made a decision, people prefer consonant over dissonant information. The authors found that following mortality salience, people indeed showed an increased preference for information that supported their decision compared to information conflicting with it. However, this only occurred with regard to a worldview-relevant decision case. For a fictitious decision scenario, mortality salience did not affect information seeking. Practical and theoretical implications are discussed.

    Full Text Available BACKGROUND: An effort to promote participation in any type of PA is more effective when it is aimed at needs, interests and preferences of particular target group. Current evidence emphasizes the insufficiency of PA in all age groups. OBJECTIVE: The purpose of the study was to analyze and describe the structure of sport activity preferences of high school students and to contribute to prospective improvement of sports and physical activity programs. METHODS: Two standardized questionnaires were used – 1. sport preferences questionnaire, 2. international physical activity questionnaire (IPAQ. The research sample (N = 333 consisted of high school students from the Czech Republic. RESULTS: Our results confirm that the differences between girls and boys are not as great as they were few decades ago. There is a visible dynamic in the development of sport preferences structure. Despite this fact there is a spectrum of sports that are constantly preferred – soccer, volleyball, aerobics and swimming. Acquired results indicate that the range of PA amount in girls varies from 2,372 MET-min/week (15 year old girls to 4,467 MET-min/week (17 year old girls, while acquired results in boys varies from 2,535 MET-min/week (16 year old boys to 4,973 MET-min/week (17 year old boys. The results, if properly applied, could increase the total amount of PA in high school students and improve the effectiveness of school PE.

    This study examined the prevalence, willingness to report, and treatment preferences for suicidal ideation among state prison inmates. The Beck Scale for Suicide Ideation (BSS) and a novel questionnaire were completed by 67 inmate-patients. The BSS score was in the high range for 15% of general population (GP) and 40% of Intermediate Care Program (ICP) patients, with 19% of ICP inmates reporting a "moderate to strong" desire to commit suicide. A majority (64% GP, 86% ICP) had prior suicide attempt(s). Forty-two percent of GP and 31% of ICP inmate-patients were unlikely to tell mental health staff about suicidal thoughts. Family contact and talking with mental health staff were preferred interventions. ICP inmates preferred staff visits and observation in their own cells, but GP inmates did not. Only a small minority (14% GP, 21% ICP) favored transfer to a crisis observation cell, but the least desired option was talking to a corrections officer. While many inmate-patients reported experiencing suicidal thoughts, they preferred not to inform staff. Almost 80% did not favor the current primary intervention: the observation cell. Alternative or supplementary options should be considered. Copyright © 2013 John Wiley & Sons, Ltd.

  13. Child sexual abuse and mandatory reporting intervention preservice content preferred by student teachers.

    2014-01-01

    The importance of preservice university teacher training about child sexual abuse and its mandatory reporting intervention is addressed in educational literature, although very little is known about student teachers' learning interests and preferences in this area. In this article, student teachers refer to students in university who are training to become teachers whose training includes teaching experiences in schools. This study examines the content about child sexual abuse and its intervention that student teachers believe they should learn. Results based on quantitative analyses show the relative importance of gender in determining responses to questions about university training and, to a lesser extent, the importance of a previous acquaintance with victims of sexual abuse, previous employment, and the length of the university course. Results based on qualitative data show that content knowledge preferred by elementary/primary and secondary school student teachers includes the teacher's role in mandatory reporting of child sexual abuse and signs, experiences, and responses to student disclosure. Student teachers prefer content examples of school professionals' responses and procedures after disclosure and prefer direct learning content from intervening school professionals. These outcomes could usefully guide teachers and educators who design intervention curricula on child sexual abuse for preservice teachers.

  14. Preferences for spicy foods and disgust of ectoparasites are associated with reported health in humans

    2011-01-01

    Full Text Available Infectious diseases that influence human survival are responsible for the evolved emotional, cognitive and behavioural strategies that reduce the risk of disease transmission. The preference for spices in foods of contemporary humans was thought to be an antipathogen strategy that could reduce disease transmission. We investigated the possible associations between reported health and anti-pathogen strategies in a sample of Slovak high school students. We found that the reported consumption of spices and ectoparasite avoidance was positively associated with the total number of reported illnesses in the last year and hand washing was negatively associated with this. This means that immunologically compromised people prefer spices more and avoid contact with disease-relevant insect vectors more than their healthier counterparts. Females engaged in anti-pathogen behaviours more than males, but consumed spicy foods less frequently, suggesting their evolutionary role in the maternal investment to their offspring or different susceptibility to certain diseases. Our results suggest that people vulnerable to diseases are more disgust sensitive and prefer foods with antimicrobial properties more than healthy people, supporting an idea that human emotions and behaviour are influenced by the threat of parasites.

    PV performance models are used to quantify the value of PV plants in a given location. They combine the performance characteristics of the system, the measured or predicted irradiance and weather at a site, and the system configuration and design into a prediction of the amount of energy that will be produced by a PV system. These predictions must be as accurate as possible in order for finance charges to be minimized. Higher accuracy equals lower project risk. The Increasing Prediction Accuracy project at Sandia focuses on quantifying and reducing uncertainties in PV system performance models.

  17. Increased anxiety, voluntary alcohol consumption and ethanol-induced place preference in mice following chronic psychosocial stress.

    2013-07-01

    Stress exposure is known to be a risk factor for alcohol use and anxiety disorders. Comorbid chronic stress and alcohol dependence may lead to a complicated and potentially severe treatment profile. To gain an understanding of the interaction between chronic psychosocial stress and drug exposure, we studied the effects of concomitant chronic stress exposure on alcohol reward using two-bottle choice and ethanol-conditioned place preference (CPP). The study consisted of exposure of the chronic subordinate colony (CSC) mice "intruders" to an aggressive "resident" mouse for 19 consecutive days. Control mice were single housed (SHC). Ethanol consumption using two-bottle choice paradigm and ethanol CPP acquisition was assessed at the end of this time period. As expected, CSC exposure increased anxiety-like behavior and reduced weight gain as compared to SHC controls. Importantly, in the two-bottle choice procedure, CSC mice showed higher alcohol intake than SHC. When testing their response to ethanol-induced CPP, CSC mice achieved higher preference for the ethanol-paired chamber. In fact, CSC exposure increased ethanol-CPP acquisition. Taken together, these data demonstrate the long-term consequences of chronic psychosocial stress on alcohol intake in male mice, suggesting chronic stress as a risk factor for developing alcohol consumption and/or anxiety disorders.

    Achieving food security in an environmentally sustainable manner is one of the biggest challenges of our time. Using insects as food can serve this purpose because they are nutritionally valuable and environmentally friendly. Embracing insects as food requires information on potential consumer...... demand as this would determine the success of product development. In this study, we present one of the first thorough assessments of consumer demand for an insect-based food. We assessed the demand in terms of Kenyan consumer preferences and willingness to pay for buns containing varying amounts...... market shares than standard buns. Results also suggested that a market for breads made with cricket flour is likely in Kenya since the demand is present. This signals that insect-based food products may serve as a viable and demand-driven way to increase food security in Kenya in the future....

  19. β-Lactamase inhibitor, clavulanic acid, attenuates ethanol intake and increases glial glutamate transporters expression in alcohol preferring rats.

    Studies from our laboratory showed that upregulation of glutamate transporter 1 (GLT-1) and cystine-glutamate exchanger (xCT) expression with ceftriaxone, β-lactam antibiotic, in the brain was associated with attenuation of ethanol consumption. In this study, we tested clavulanic acid, which is another β-lactam compound with negligible antimicrobial activity, on ethanol consumption and expression of GLT-1, xCT and glutamate aspartate transporter (GLAST) in male alcohol-preferring (P) rats. Clavulanic acid has the central β-lactam pharmacophore that is critical for the upregulation of GLT-1 and xCT expression. We found that clavulanic acid, at 5mg/kg (i.p.) dose, significantly attenuated ethanol consumption and ethanol preference in P rats as compared to vehicle-treated group. This effect was associated with a significant increase in water intake in clavulanic acid treated group. Importantly, we found that clavulanic acid increased the expression of GLT-1 and xCT in nucleus accumbens. However, there was no effect of clavulanic acid on GLAST expression in the nucleus accumbens. Clavulanic acid treatment did not upregulate the expression of GLT-1, xCT and GLAST in prefrontal cortex. These findings revealed that clavulanic acid at 20-40 fold lower dose than ceftriaxone can attenuate ethanol consumption, in part through upregulation of GLT-1 and xCT expression in the nucleus accumbens. Thus, we suggest that clavulanic acid might be used as an alternative option to ceftriaxone to attenuate ethanol drinking behavior. Copyright © 2017 Elsevier B.V. All rights reserved.

    The purpose of the present paper is to provide an introduction to the theory of social choice and related disciplines, and to relate this theory to the concrete problem of nuclear waste management. In Section I of this report, an overview of the problem is provided. In Section II, two candidate preference aggregation procedures that can be used to identify a socially optimal waste management policy are identified. In Section III, a somewhat lengthy defense of the use of these two aggregation procedures is presented. Each is shown to be compatible with four intuitively appealing criteria of collective decision-making. In Section IV the application of one of the procedures to the evaluation of waste management alternatives is discussed. In Section V the problem of inferring evaluation parameters from expert and laypersons' judgments is addressed.

    When rodents are reared in isolation from young age onwards, they manifest a number of behavioural alterations in adulthood. Since some of these alterations resemble symptoms of psychiatric disorders, the post-weaning social isolation (ISO) manipulation is often applied to create rodent models of these disorders. In rats, ISO effects have been thoroughly characterised, but in mice they are less well documented. Therefore, we further evaluated behaviour of adult ISO mice with a test battery that focussed on abnormalities relevant to schizophrenia. We found that ISO mice were hyperactive during the dark phase. Also, ISO mice showed alterations in magnitude, habituation and prepulse-inhibition of the acoustic startle reflex, increased anxiety, increased social preference and changes in extinction of fear responses. We did not observe increased sensitivity to locomotor-activating effects of amphetamine. It is concluded that ISO of mice might serve as a useful model to test further hypotheses regarding pathogenesis occurring at specific developmental timeframes. Copyright © 2011 Elsevier Inc.

    Patient safety event reporting is an important component for fostering a culture of safety. Our tertiary care hospital utilizes a computerized patient safety event reporting system that has been historically underutilized by residents and faculty, despite encouragement of its use. The objective of this quality project was to increase patient safety event reporting within our Emergency Medicine residency program. Knowledge of event reporting was evaluated with a survey. Eighteen residents and five faculty participated in a formal educational session on event reporting followed by feedback every two months on events reported and actions taken. The educational session included description of which events to report and the logistics of accessing the reporting system. Participants received a survey after the educational intervention to assess resident familiarity and comfort with using the system. The total number of events reported was obtained before and after the educational session. After the educational session, residents reported being more confident in knowing what to report as a patient safety event, knowing how to report events, how to access the reporting tool, and how to enter a patient safety event. In the 14 months preceding the educational session, an average of 0.4 events were reported per month from the residency. In the nine months following the educational session, an average of 3.7 events were reported per month by the residency. In addition, the reported events resulted in meaningful actions taken by the hospital to improve patient safety, which were shared with the residents. Improvement efforts including an educational session, feedback to the residency of events reported, and communication of improvements resulting from reported events successfully increased the frequency of safety event reporting in an Emergency Medicine residency.

    Comprehensive sex education programs specifically designed for adolescents and young adults that take into account gender norms and cultural background have shown promise as a means of countering the high sexually transmitted infection rate in young people. Recently, digital gaming interventions delivered on computers or mobile devices have emerged as another way to promote safer sex behavior in a young population. Tailoring these computer-based interventions to their target population has been recognized to increase positive behavior outcomes. In this qualitative study, we investigated whether young female and male adults from two different cultural backgrounds (all living in Germany) would have different preferences and needs in relation to an educational game promoting safer sex. We conducted four semistructured focus group interviews comprising open-ended questions with male and female participants who had either a German or a Turkish background. In total, 20 individuals, aged between 18 and 22 years, from two socially diverse and ethnically mixed vocational schools in Germany participated. Independent of cultural background and gender, participants preferred a real-world design with a first-person visual perspective over a fantasy-like third-person perspective. Furthermore, they preferred highly customizable avatars. All participants mentioned the importance of including an alcohol-intoxicated avatar and most participants wanted there to be additional information available about various safer sex approaches and about the use of different barrier protection methods. Males and females reported similar preferences for the design of an educational game promoting safer sex, with the only difference being exactly how the topic of having sexual intercourse should be addressed in the game. Males preferred a direct approach, whereas females had a preference for treating this subject more sympathetically. Educational games offer anonymity and can provide young people

    Systematic reviews and meta-analyses of individual participant data (IPD) aim to collect, check, and reanalyze individual-level data from all studies addressing a particular research question and are therefore considered a gold standard approach to evidence synthesis. They are likely to be used with increasing frequency as current initiatives to share clinical trial data gain momentum and may be particularly important in reviewing controversial therapeutic areas. To develop PRISMA-IPD as a stand-alone extension to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) Statement, tailored to the specific requirements of reporting systematic reviews and meta-analyses of IPD. Although developed primarily for reviews of randomized trials, many items will apply in other contexts, including reviews of diagnosis and prognosis. Development of PRISMA-IPD followed the EQUATOR Network framework guidance and used the existing standard PRISMA Statement as a starting point to draft additional relevant material. A web-based survey informed discussion at an international workshop that included researchers, clinicians, methodologists experienced in conducting systematic reviews and meta-analyses of IPD, and journal editors. The statement was drafted and iterative refinements were made by the project, advisory, and development groups. The PRISMA-IPD Development Group reached agreement on the PRISMA-IPD checklist and flow diagram by consensus. Compared with standard PRISMA, the PRISMA-IPD checklist includes 3 new items that address (1) methods of checking the integrity of the IPD (such as pattern of randomization, data consistency, baseline imbalance, and missing data), (2) reporting any important issues that emerge, and (3) exploring variation (such as whether certain types of individual benefit more from the intervention than others). A further additional item was created by reorganization of standard PRISMA items relating to interpreting results. Wording

    2009-02-15

    The lack of appropriate animal models for bipolar disorder (BPD) is a major factor hindering the research of its pathophysiology and the development of new drug treatments. In line with the notion that BPD might represent a heterogeneous group of disorders, it was suggested that models for specific domains of BPD should be developed and then integrated. The present study tested sweet solution preference as a rodent model for increased reward seeking, a central component of manic behavior and a possible endophenotype of the disorder. The study identified that Black Swiss mice show high baseline saccharin preference compared with C57bl/6, CBA/J and A/J strains. Sweet solution preference in Black Swiss mice was therefore evaluated across a number of saccharin concentrations, with or without treatment with the mood stabilizers lithium and valproate and the antidepressant imipramine. Results indicated that the structurally dissimilar mood stabilizers lithium and valproate, but not the antidepressant imipramine, reduce sweet solution preference. However, different dosing schedules were needed for the two drugs to induce this effect. These findings support the face and the predictive validity of the sweet solution preference test as an animal model for the elevated reward-seeking domain of mania. As such, this test might be well integrated into a battery of models for different domains of BPD. Such a battery can be effectively utilized to screen new treatments, to distinguish between specific effects of different drugs, and to explore the mechanisms underlying BPD.

    Background The coverage of insecticide-treated nets (ITNs) remains low despite existing distribution strategies, hence, it was important to assess consumers' preferences for distribution of ITNs, as well as their perceptions and expenditures for malaria prevention and to examine the implications for scaling-up ITNs in rural Nigeria. Methods Nine focus group discussions (FGDs) and questionnaires to 798 respondents from three malaria hyper-endemic villages from Enugu state, south-east Nigeria were the study tools. Results There was a broad spectrum of malaria preventive tools being used by people. The average monthly expenditure on malaria prevention per household was 55.55 Naira ($0.4). More than 80% of the respondent had never purchased any form of untreated mosquito net. People mostly preferred centralized community-based sales of the ITNS, with instalment payments. Conclusion People were knowledgeable about malaria and the beneficial effects of using nets to protect themselves from the disease. The mostly preferred community-based distribution of ITNs implies that the strategy is a potential untapped additional channel for scaling-up ITNs in Nigeria and possibly other parts of sub-Saharan Africa.

    This study reviews the environmental implications of continued and increased use of biomass for energy to determine what concerns have been and need to be addressed and to establish some guidelines for developing future resources and technologies. Although renewable biomass energy is perceived as environmentally desirable compared with fossil fuels, the environmental impact of increased biomass use needs to be identified and recognized. Industries and utilities evaluating the potential to convert biomass to heat, electricity, and transportation fuels must consider whether the resource is reliable and abundant, and whether biomass production and conversion is environmentally preferred. A broad range of studies and events in the United States were reviewed to assess the inventory of forest, agricultural, and urban biomass fuels; characterize biomass fuel types, their occurrence, and their suitability; describe regulatory and environmental effects on the availability and use of biomass for energy; and identify areas for further study. The following sections address resource, environmental, and policy needs. Several specific actions are recommended for utilities, nonutility power generators, and public agencies.

    The abuse of morphine has risen considerably in recent years, mainly due to the increase of its prescription in clinical medicine. Also, increased consumption of processed foods, rich in trans fatty acids (TFA), has caused concerns about human health. Thus, the aim of our study was to determine whether trans fat consumption in the perinatal period may affect preference for morphine in adolescent female and male rats. Dams were orally supplemented with water (C-control) or hydrogenated vegetable fat (HVF-rich in TFA) during gestation and lactation periods. On post-natal day 43, pups were exposed to morphine (4mg/kg i.p., for 4 days) and assessed in the conditioned place preference paradigm. Anxiety-like symptoms were assessed, and oxidative status of the brain was estimated by reactive species (RS) generation. Female rats with HVF supplementation showed increased morphine preference and less anxiety-like symptoms. Additionally, both male and female rats from HVF-supplementation showed increased RS generation in the ventral tegmental area, whose level was similar in morphine-conditioned female rats. RS generation was increased in the hippocampus of morphine-conditioned female rats, regardless of the supplementation of their dams. We may infer that gender is a predictive factor to opioid preference, since adolescent female rats showed more susceptibility to addiction than males. Furthermore, trans fat consumption across the perinatal period is able to modify parameters of opioid preference in female rats, possibly due to TFA incorporation in phospholipid membranes, modifying the endogenous opioid system and the oxidative status in brain areas related to drug addiction.

  17. Product Variety, Consumer Preferences, and Web Technology: Can the Web of Data Reduce Price Competition and Increase Customer Satisfaction?

    Science.gov (United States)

    Hepp, Martin

    E-Commerce on the basis of current Web technology has created fierce competition with a strong focus on price. Despite a huge variety of offerings and diversity in the individual preferences of consumers, current Web search fosters a very early reduction of the search space to just a few commodity makes and models. As soon as this reduction has taken place, search is reduced to flat price comparison. This is unfortunate for the manufacturers and vendors, because their individual value proposition for a particular customer may get lost in the course of communication over the Web, and it is unfortunate for the customer, because he/she may not get the most utility for the money based on her/his preference function. A key limitation is that consumers cannot search using a consolidated view on all alternative offers across the Web. In this talk, I will (1) analyze the technical effects of products and services search on the Web that cause this mismatch between supply and demand, (2) evaluate how the GoodRelations vocabulary and the current Web of Data movement can improve the situation, (3) give a brief hands-on demonstration, and (4) sketch business models for the various market participants.

    Nearly one million women each year have pregnancy complications that cause antepartum and postpartum anxiety and depression. This exploratory study determined 1) feasibility of using social media to recruit women with depressive symptoms following high risk pregnancy, 2) women's barriers to treatment, 3) use of online resources for assistance with PPD, and 4) preferences for internet treatment. Among a national sample of 53 women, nearly 70% had major depression. Common barriers were lack of time and stigma. Over 90% of women would use the internet to learn coping strategies for PPD. Women expressed interest in web-based PPD treatment and identified desired characteristics of an intervention.

  20. Valuation of Go Stimuli or Devaluation of No-Go Stimuli? Evidence of an Increased Preference for Attended Go Stimuli Following a Go/No-Go Task.

    Attentional inhibition that occurs during discrimination tasks leads to the negative evaluation of distractor stimuli. This phenomenon, known as the distractor devaluation effect also occurs when go/no-go tasks require response inhibition. However, it remains unclear whether there are interactions between attention and response controls when the distractor devaluation effect occurs. The aims of this study were to investigate whether attention to stimuli in the go/no-go task plays a facilitative role in distractor devaluation through response inhibition, and to clarify whether this effect reflects a decreased preference for no-go stimuli. Participants evaluated the preference for pictures before and after a go/no-go task. In Experiments 1 and 2, they made a go or no-go response depending on the category of pictures displayed (gummy candies or rice crackers), whereas in Experiment 3 they did on the basis digit category, even or odd numbers, superimposed on such pictures. Experiments 1 and 2 demonstrated that the pictures presented as no-go stimuli in the preceding go/no-go task were evaluated as less positive than the pictures presented as go stimuli. This devaluation effect reflected an increased preference for the go stimuli but not a decreased preference for the no-go stimuli. Experiment 3 indicated that response inhibition did not affect the preference for the pictures that had not received attention in a preceding go/no-go task. These results suggest that although attention plays an important role in differential ratings for go and no-go stimuli, such differences, in fact, reflect the valuation of go stimuli.

    Full Text Available Unilateral anterior cruciate ligament (ACL tear is a common injury seen by sports medicine orthopedic surgeons. However, a bilateral simultaneous ACL injury is extremely rare and has been reported only three times in the literature. We present a young female skier with simultaneous bilateral ACL tears that were managed with staged ACL reconstruction. We then conducted a nationwide survey (United States to determine the prevalence of simultaneous bilateral ACL tear and preferred management strategies by sports medicine orthopedic surgeons. Sports medicine fellowship directors were contacted and asked to send an 8-item survey to colleagues (sports medicine fellowship trained surgeons asking about overall number of ACL reconstructions performed, number of bilateral simultaneous ACL injuries seen and optimal management strategies of such an injury. Out of 43 responses, only 22 (51.2% surgeons had seen a bilateral simultaneous ACL injury. Of these, 16 (76.2% preferred staged reconstruction. Graft choice was mixed between autograft and allograft, but a large majority preferred either patellar tendon autograft (58% or hamstring autograft (41% were the most common choice. Staged reconstruction is the treatment of choice by surgeons surveyed in our study.

    The Good Behavior Game (GBG) is a universal classroom-based preventive intervention directed at reducing early aggressive, disruptive behavior and improving children's social adaptation into the classroom. The GBG is one of the few universal preventive interventions delivered in early elementary school that has been shown to reduce the risk for future suicide attempts. This paper addresses one potential mechanism by which the GBG lowers the risk of later suicide attempt. In this study, we tested whether the GBG, by facilitating social adaptation into the classroom early on, including the level of social preference by classmates, thereby lowers future risk of suicide attempts. The measure of social adaptation is based on first and second grade peer reports of social preference ("which children do you like best?"; "which children don't you like?"). As part of the hypothesized meditational model, we examined the longitudinal association between childhood peer social preference and the risk of future suicide attempt, which has not previously been examined. Data were from an epidemiologically based randomized prevention trial, which tested the GBG among two consecutive cohorts of first grade children in 19 public schools and 41 classrooms. Results indicated that peer social preference partially mediated the relationship between the GBG and the associated reduction of risk for later suicide attempts by adulthood, specifically among children characterized by their first grade teacher as highly aggressive, disruptive. These results suggest that positive childhood peer relations may partially explain the GBG-associated reduction of risk for suicide attempts and may be an important and malleable protective factor for future suicide attempt.

    2008-11-01

    Previous research suggests a possible link between eveningness and general difficulties with self-regulation (e.g., evening types are more likely than other chronotypes to have irregular sleep schedules and social rhythms and use substances). Our study investigated the relationship between eveningness and self-regulation by using two standardized measures of self-regulation: the Self-Control Scale and the Procrastination Scale. We predicted that an eveningness preference would be associated with poorer self-control and greater procrastination than would an intermediate or morningness preference. Participants were 308 psychology students (mean age=19.92 yrs) at a small Canadian college. Students completed the self-regulation questionnaires and Morningness/Eveningness Questionnaire (MEQ) online. The mean MEQ score was 46.69 (SD=8.20), which is intermediate between morningness and eveningness. MEQ scores ranged from definite morningness to definite eveningness, but the dispersion of scores was skewed toward more eveningness. Pearson and partial correlations (controlling for age) were used to assess the relationship between MEQ score and the Self-Control Scale (global score and 5 subscale scores) and Procrastination Scale (global score). All correlations were significant. The magnitude of the effects was medium for all measures except one of the Self-Control subscales, which was small. A multiple regression analysis to predict MEQ score using the Self-Control Scale (global score), Procrastination Scale, and age as predictors indicated the Self-Control Scale was a significant predictor (accounting for 20% of the variance). A multiple regression analysis to predict MEQ scores using the five subscales of the Self-Control Scale and age as predictors showed the subscales for reliability and work ethic were significant predictors (accounting for 33% of the variance). Our study showed a relationship between eveningness and low self-control, but it did not address whether the

    Children's low vegetable consumption requires effective strategies to enhance preference for and intake of vegetables. The study compared three preparation practices for a target vegetable (spinach) on their effectiveness in increasing preschool-aged children's preference for and intake of the target vegetable in comparison to a control vegetable (green beans). We conducted a randomized controlled trial with four parallel groups: plain spinach, creamed spinach, spinach ravioli, and green beans. During the intervention, children were served the vegetable at their main meal six times over 6 weeks at home. Children aged 2 to 4 years were recruited from six child-care centers located in Wageningen, the Netherlands, and randomly assigned to one of the four groups, with vegetable products provided by the researchers. The study was performed between September 2014 and January 2015. In total, 103 children participated, with 26, 25, 26, and 26 in the plain spinach, creamed spinach, spinach ravioli, and green beans groups, respectively. Preference for and ad libitum intake of cooked spinach were assessed during a test meal at the day-care center pre- and postintervention. Food neophobia was assessed via the Child Food Neophobia Scale. General linear model repeated measures analysis, including food neophobia, spinach liking, exposure, and consumption scores as covariates, was performed to test for effects of group on intake. Logistic regression was used to assess changes in preference between pre- and postintervention. All four groups significantly increased their spinach intake from pre- (53 g) to postintervention (91 g) by an average of 70%. For preference, no significant shift toward the target vegetable was found from pre- to postintervention. The effect on intake depended on the child's neophobia status and preintervention spinach consumption, with children with neophobia being less responsive to the intervention and with children who ate more spinach before the

    Weight loss surgery (WLS) is efficacious for long-term weight reduction and decreases overall mortality in severely obese patients. The mechanisms implicated in long-term weight loss are not fully understood. Proposed mechanisms include changes in gut hormones and brain regulation of appetite and satiety. We aimed to investigate the long-term ghrelin and leptin profiles and changes in food preference and eating behavior after WLS in adolescent patients. Two obese females aged 15 years and 14 4/12 years, who did not respond to lifestyle changes, including dietary intervention and physical exercise in combination with medical therapy, underwent robotic-assisted gastroplication. Anthropometric measurements, food habits and eating behavior, as well as metabolic and hormonal changes during long-term post-surgical follow-up were monitored. Long-term weight reduction was obtained in both patients, with a significant decrease in waist circumference. Resting energy expenditure showed a decrease over time, with a respiratory quotient that increased showing a shift from oxidation of a high-fat diet before surgery to oxidation of a mixed diet two and three years later. Both subjects improved their eating habits and lifestyle. Co-morbidity resolution was also noted. Increased pre-prandial ghrelin levels as well as higher post-prandial ghrelin and a leptin drop compared with pre-surgery values were observed in both patients. Persistent weight loss after gastroplication is associated with a favorable change in gut hormones and food preferences. The role of hormonal and sensory components in long-term results seems crucial. Particularly in adolescent patients, a multidisciplinary approach and continuous nutritional care is mandatory for weight maintenance and consolidation of changes.

    Healthy children and undergraduates were observed for hand preference and measured for hand skill in representative samples collected over some years. Writing and throwing were observed for 2844 participants drawn from primary, secondary and higher levels of education. The 12 actions of a standard questionnaire were observed for 2388 secondary school children and undergraduates. These findings provide normative data for comparison with selected samples that may be classified in a variety of ways, including subgroups previously defined and ordered for relative hand skill. Differences between the sexes were found only for certain subgroups of right-mixed-handers. Undergraduates were less variable for hand skill asymmetry than schoolchildren. Interpretations in the light of the RS theory show why statistical effects for comparisons with selected groups are likely to be small. Increased non-right-handedness may be caused by several influences on cerebral dominance, natural and pathological.

    Mallett, Robyn K; Melchiori, Kala J

    2014-05-01

    Although most women assume they would confront sexism, assertive responses are rare. We test whether women's preference for respect or liking during interpersonal interactions explains this surprising tendency. Women report preferring respect relative to liking after being asked sexist, compared with inappropriate, questions during a virtual job interview (Study 1, n = 149). Women's responses to sexism increase in assertiveness along with their preference for being respected, and a respect-preference mediates the relation between the type of questions and response assertiveness (Studies 1 and 2). In Study 2 (n = 105), women's responses to sexist questions are more assertive when the sense of belonging is enhanced with a belonging manipulation. Moreover, preference for respect mediates the effect of the type of questions on response assertiveness, but only when belonging needs are met. Thus the likelihood of confrontation depends on the goal to be respected outweighing the goal to be liked.

    Several recent reports have linked the use of dopamine agonists (DAs) to a variety of compulsive behaviors in patients with Parkinson's disease (PD). These inappropriate behaviors may include pathological gambling, compulsive shopping, and hypersexuality. To report the case of a patient with increased range of sexual behavior after use of pramipexole, a DA. A 67-year-old man with a 7-year diagnosis of PD treated with levodopa and pramipexole presented with a dramatic change in sexual behavior after an increase in DA dose. The patient, who historically was a very shy and conservative person, started to present increased frequency of sexual intercourse with his wife, during which he began speaking obscenities with an extreme preference for anal intercourse, preferences never requested before. After pramipexole was withdrawn, complete remission was observed with return to his usual sexual behavior. Hypersexuality and paraphilias are complications not uncommonly found in patients with PD under dopaminergic treatment. Further studies are needed for the understanding of this complex complication, and particularly the most prevalent relationship between pathological hypersexuality and use of DAs.

    This study used focus groups to identify preferences for physical activity (PA) and motivational themes for increasing PA in underserved adolescents. Fifty-one adolescents, on the free lunch program (25 males and 26 females; ages 10-13 years; 72% African-American, 19% white, and 9% other minorities) participated in focus groups (6-10 children per group; same gender). The data were transcribed and coded into themes. A content analysis was performed using QSR NVivo. Boys rated their favorite activities as playing basketball, football, soccer, and baseball. Girls rated their favorite activities as playing basketball, swimming, and roller-skating. For motivational themes, boys and girls most frequently stated that they would participate in PA if it was a fun, provided a health benefit, and if there were a variety of choices offered. Being involved with friends was also identified as important to both boys and girls. The findings from this qualitative study suggest that including components of choice and a variety of physical activities may be important elements for intervention programs in underserved adolescents.

    This article discussed results of the 2008 Green Index survey conducted by Autodesk Inc., a company that is committed to developing software for easier and more efficient sustainable building design. The survey, which questioned members of the American Institute of Architects (AIA), revealed that architects and building owners have increased the implementation of sustainable design practices in response to a greater demand from clients. An increase in implementing green building elements of 15 per cent from 2007 may indicate a shift in attitude towards climate change. The primary reasons clients are asking for green buildings are reduced operating costs, marketing and marketing demand. The survey showed that 41 per cent of architects are using software to help predict and evaluate the environmental impact and lifecycle of their buildings as well as the HVAC operating costs and alternative building materials. The survey also showed that 24 per cent of architects are currently implementing green roofs on more than half of their new projects, compared with 7 per cent in 2007. Also, 39 per cent are using renewable, on-site energy sources such as solar, wind ,geothermal, low impact hydro, or biomass on more than half of new building designs compared with only 6 per cent in 2007. 1 ref.

    The topic of preferences is a new branch of machine learning and data mining, and it has attracted considerable attention in artificial intelligence research in previous years. It involves learning from observations that reveal information about the preferences of an individual or a class of individuals. Representing and processing knowledge in terms of preferences is appealing as it allows one to specify desires in a declarative way, to combine qualitative and quantitative modes of reasoning, and to deal with inconsistencies and exceptions in a flexible manner. And, generalizing beyond traini

    Clinical evidence suggests that intrauterine growth restriction (IUGR) can cause persistent changes in the preference for palatable foods. In this study, we compared food preferences, the response to food rewards, and the role of the mesolimbic dopaminergic system in feeding behavior, between IUGR and control rats. Time-mated pregnant Sprague-Dawley rats were randomly allocated to a control group (standard chow ad libitum) or a 50% food restriction (FR) group, which received 50% of the control dams׳ habitual intake. These diets were provided from gestation day 10 to the 21st day of lactation. Within 24h of birth, pups were cross-fostered and divided into four groups: Adlib/Adlib, FR/Adlib, FR/FR, Adlib/FR. Standard chow consumption was compared between all groups. Food preferences, conditioned place preference to a palatable diet, and the levels of tyrosine hydroxylase (TH) phosphorylation and D2 receptors in the nucleus accumbens were analyzed and compared between the two groups of interest: Adlib/Adlib (control) and FR/Adlib (exposed to growth restriction during the fetal period only). IUGR adult rats had a stronger preference for palatable foods, but showed less conditioned place preference to a palatable diet than controls. D2 receptors levels were lower in IUGR rats. At baseline, TH and pTH levels were higher in FR/Adlib than control males. Measurements taken after exposure to sweet foods revealed higher levels of TH and pTH in FR/Adlib than control females. These data showed that IUGR rats exhibited a preference for palatable foods, potentially due to alterations in their mesolimbic reward pathway. Additionally, the changes observed in the mesolimbic dopaminergic system of IUGR rats proved to be sex-specific. This article is part of a Special Issue entitled 1618. Copyright © 2015 Elsevier B.V.

    The Timed Up and Go (TUG) test, as a measure of objective functional impairment in lumbar degenerative disk disease (DDD), complements patient-reported outcome measures (PROMs) of subjective functional impairment. Prospective 2-center study on consecutive patients scheduled for surgical treatment for lumbar DDD who underwent an objective (TUG test) and subjective (PROMs) functional assessment before and 1 and 3 days after surgery. PROMs included the visual analog scale (VAS), Roland-Morris Disability Index (RMDI), Oswestry Disability Index (ODI), Euro-Qol (EQ-5D), and Short Form 12 (SF-12) questionnaires. On completion of each assessment, patients were asked whether they would prefer performing the TUG test or completing the PROMs questionnaires. A total of 109 of 125 patients (87.2%) completed the assessments. Preoperatively, patients were 2.18 times as likely to prefer the TUG test to the PROMs (odds ratio [OR], 2.18; 95% confidence interval [CI], 1.27-3.75). On postoperative days 1 and 3, patients were 5.79 (OR, 5.79; 95% CI, 3.23-10.37) and 6.33 times as likely to prefer the TUG test to the PROMs, respectively (OR, 6.33; 95% CI, 3.51-11.41). There were no statistical differences in baseline characteristics, TUG t scores, VAS, RMDI, ODI, SF-12, and EQ-5D index between patients preferring either the TUG test or the PROMs questionnaires. The TUG test is preferred over a battery of PROMs by 60%-70% of patients with lumbar DDD not only in the preoperative, but also in the postoperative, setting. High functional disability does not result in avoidance of the TUG test, and repeated assessments lead to higher preference. Copyright © 2016 Elsevier Inc. All rights reserved.

    Background Clinically and biologically, ASD is heterogeneous. Unusual patterns of visual preference as indexed by eye-tracking are hallmarks, yet whether they can be used to define an early biomarker of ASD as a whole, or leveraged to define a subtype is unclear. To begin to examine this issue, large cohorts are required. Methods A sample of 334 toddlers from 6 distinct groups (115 ASD, 20 ASD-Features, 57 DD, 53 Other, 64 TD, and 25 Typ SIB) participated. Toddlers watched a movie containing both geometric and social images. Fixation duration and number of saccades within each AOI and validation statistics for this independent sample computed. Next, to maximize power, data from our previous study (N=110) was added totaling 444 subjects. A subset of toddlers repeated the eye-tracking procedure. Results As in the original study, a subset of toddlers with ASD fixated on geometric images greater than 69%. Using this cutoff, sensitivity for ASD was 21%, specificity 98%, and PPV 86%. Toddlers with ASD who strongly preferred geometric images had (a) worse cognitive, language, and social skills relative to toddlers with ASD who strongly preferred social images and (b) fewer saccades when viewing geometric images. Unaffected siblings of ASD probands did not show evidence of heightened preference for geometric images. Test-retest reliability was good. Examination of age effects suggest that this test may not be appropriate with children > 4 years. Conclusions Enhanced visual preference for geometric repetition may be an early developmental biomarker of an ASD subtype with more severe symptoms. PMID:25981170

    Recent research has consistently demonstrated reduced orienting to social stimuli in samples of young children with autism spectrum disorders (ASD). However, social orienting greatly varies between individual children on the spectrum. Better understanding this heterogeneity in social orienting may contribute to our comprehension of the mechanisms underlying autistic symptoms thereby improving our ability to intervene. Indeed, children on the autism spectrum who show higher levels of interest in social stimuli demonstrate reduced clinical symptoms and increased adaptive functioning. However, longitudinal studies examining the influence of social orienting on subsequent outcome are critically lacking. Here, we aim to explore the relationship between social interest at the age of 3 and changes in severity of autistic symptoms over the subsequent year, in 20 children with ASD and 20 age-matched typically developing (TD) children. A visual preference for social stimuli was measured using an eye-tracking task at baseline, consisting of a previously studied visual preference paradigm presenting biological and geometric motion side-by-side. The task was altered for the current study by alternating presentation side for each type of stimuli to keep visual perseveration from influencing participants’ first fixation location. Clinical data were collected both at baseline and 1 year later at follow-up. As a group, we observed reduced interest for biological motion (BIO-M) in children with ASD compared to TD children, corroborating previous findings. We also confirmed that a preference for BIO-M is associated with better adaptive functioning in preschoolers with ASD. Most importantly, our longitudinal results showed that a preference for BIO-M strongly predicted decreased severity of diagnostic symptoms. Participants who preferred social stimuli at the age of 3 showed drastic reductions in their severity level of autistic symptoms 1 year later, whereas participants who

  14. Sequential effects in preference decision: Prior preference assimilates current preference.

    An important factor affecting preference formation is the context in which that preference decision takes place. The current research examined whether one's preference formed for a previously presented stimulus influences the processing of a subsequent preference decision, henceforth referred to as the preference sequence effect. Using a novel sequential rating/judgment paradigm, the present study demonstrated the presence of a preference sequence effect using artistic photographs and face stimuli: A neutral stimulus was preferred more following a preferable stimulus than a less preferable stimulus. Furthermore, a similar trend was found even when the potential influence of response bias was controlled. These results suggest that an assimilative sequential effect exists even when sequential judgments are made solely based on one's subjective feeling; preference formed for a preceding stimulus modulates preference for a subsequent stimulus. This implies the need for a consideration of trial sequence as a factor creating a psychological context affecting the subsequent preference decisions.

    Concussions may accelerate the progression to long-term mental health outcomes such as depression in athletes. To prospectively determine the effects of recurrent concussions on the clinical diagnosis of depression in a group of retired football players. Cohort study; Level of evidence, 2. Members of the National Football League Retired Players Association responded to a baseline General Health Survey (GHS) in 2001. They also completed a follow-up survey in 2010. Both surveys asked about demographic information, number of concussions sustained during their professional football career, physical/mental health, and prevalence of diagnosed medical conditions. A physical component summary (Short Form 36 Measurement Model for Functional Assessment of Health and Well-Being [SF-36 PCS]) was calculated from responses for physical health. The main exposure, the history of concussions during the professional playing career (self-report recalled in 2010), was stratified into 5 categories: 0 (referent), 1 to 2, 3 to 4, 5 to 9, and 10+ concussions. The main outcome was a clinical diagnosis of depression between the baseline and follow-up GHS. Classic tabular methods computed crude risk ratios. Binomial regression with a Poisson residual and robust variance estimation to stabilize the fitting algorithm estimated adjusted risk ratios. χ(2) analyses identified associations and trends between concussion history and the 9-year risk of a depression diagnosis. Of the 1044 respondents with complete data from the baseline and follow-up GHS, 106 (10.2%) reported being clinically diagnosed as depressed between the baseline and follow-up GHS. Approximately 65% of all respondents self-reported sustaining at least 1 concussion during their professional careers. The 9-year risk of a depression diagnosis increased with an increasing number of self-reported concussions, ranging from 3.0% in the "no concussions" group to 26.8% in the "10+" group (linear trend: P concussions and depression was

    The U.S. government technical report is a primary means by which the results of federally funded research and development (R&D) are transferred to the U.S. aerospace industry. However, little is known about this information product in terms of its actual use, importance, and value in the transfer of federally funded R&D. Little is also known about the intermediary-based system that is used to transfer the results of federally funded R&D to the U.S. aerospace industry. To help establish a body of knowledge, the U.S. government technical report is being investigated as part of the NASA/DOD Aerospace Knowledge Diffusion Research Project. In this paper, we summarize the literature on the U.S. government technical report and present the results of a survey of U.S. aerospace engineers and scientists that solicited their opinions concerning the format of NASA Langley Research Center (LaRC)-authored technical reports. To learn more about the preferences of U.S. aerospace engineers and scientists concerning the format of NASA LaRC-authored technical reports, we surveyed 133 report producers (i.e., authors) and 137 report users in March-April 1996.

    Background Physical inactivity is highly prevalent after stroke, increasing the risk of poor health outcomes including recurrent stroke. Tailoring of exercise programs to individual preferences can improve adherence, but no tools exist for this purpose in stroke. Methods We identified potential questionnaire items for establishing exercise preferences via: (i) our preliminary Exercise Preference Questionnaire in stroke, (ii) similar tools used in other conditions, and (iii) expert panel consultations. The resulting 35-item questionnaire (SEPI-35) was administered to stroke survivors, along with measures of disability, depression, anxiety, fatigue and self-reported physical activity. Exploratory factor analysis was used to identify a factor structure in exercise preferences, providing a framework for item reduction. Associations between exercise preferences and personal characteristics were analysed using multivariable regression. Results A group of 134 community-dwelling stroke survivors (mean age 64.0, SD 13.3) participated. Analysis of the SEPI-35 identified 7 exercise preference factors (Supervision-support, Confidence-challenge, Health-wellbeing, Exercise context, Home-alone, Similar others, Music-TV). Item reduction processes yielded a 13-item version (SEPI-13); in analysis of this version, the original factor structure was maintained. Lower scores on Confidence-challenge were significantly associated with disability (p = 0.002), depression (p = 0.001) and fatigue (p = 0.001). Self-reported barriers to exercise were particularly prevalent in those experiencing fatigue and anxiety. Conclusions The SEPI-13 is a brief instrument that allows assessment of exercise preferences and barriers in the stroke population. This new tool can be employed by health professionals to inform the development of individually tailored exercise interventions. PMID:27711242

    Full Text Available Abstract Background Non-tuberculous mycobacteria have long been identified as capable of causing human disease and the number at risk, due to immune-suppression, is rising. Several reports have suggested incidence to be increasing, yet routine surveillance-based evidence is lacking. We investigated recent trends in, and the epidemiology of, non-tuberculous mycobacterial infections in England, Wales and Northern Ireland, 1995-2006. Methods Hospital laboratories voluntarily report non-tuberculous mycobacterial infections to the Health Protection Agency Centre for Infections. Details reported include age and sex of the patient, species, specimen type and source laboratory. All reports were analysed. Results The rate of non-tuberculous mycobacteria reports rose from 0.9 per 100,000 population in 1995 to 2.9 per 100,000 in 2006 (1608 reports. Increases were mainly in pulmonary specimens and people aged 60+ years. The most commonly reported species was Mycobacterium avium-intracellulare (43%; M. malmoense and M. kansasii were also commonly reported. M. gordonae showed the biggest increase over the study period rising from one report in 1995 to 153 in 2006. Clinical information was rarely reported. Conclusions The number and rate of reports increased considerably between 1995 and 2006, primarily in older age groups and pulmonary specimens. Increases in some species are likely to be artefacts but real changes in more pathogenic species, some of which will require clinical care, should not be excluded. Enhanced surveillance is needed to understand the true epidemiology of these infections and their impact on human health.

  1. Illegal and legal parrot trade shows a long-term, cross-cultural preference for the most attractive species increasing their risk of extinction.

    Directory of Open Access Journals (Sweden)

    José L Tella

    Full Text Available Illegal trade constitutes a major threat for a variety of wildlife. A criminology framework has been recently applied to parrot poaching in Mexico, suggesting an opportunistic crime in which the most abundant and accessible species, and not the rare or highly priced species, were poached more often. We analyzed this information, together with additional long-term data (1981-2005 on both the legal and illegal trade of the 22 Mexican parrot species (n = 31,019 individuals, using multivariate statistics and hypothesis-testing approaches. Our results showed a selective capture of parrot species attending to their attractiveness. Parrot species widely differed in attractiveness to people (as reflected by their combined measures of body size, coloration, and ability to imitate human speech, and their attractiveness strongly correlated with their prices both in the Mexican and US markets. The most attractive and valuable species (amazons and macaws were disproportionally caught attending to the number of years they were legally trapped. Similar patterns were found for parrots poached for the domestic Mexican market, for those smuggled to the USA, and for those legally exported before or after 1992, when the USA ban led parrot exports to be mostly directed to European countries. Finally, the long-term cross-cultural preference for the most attractive species has led them to be among the most threatened species today. Since current parrot poaching mostly responds to local demand, socio-ecological work is needed to reverse the long-standing pet-keeping tradition that may decimate the most desired species in Neotropical countries.

    2015-05-01

    In the context of the Affordable Care Act, there is extensive emphasis on making provider quality transparent and publicly available. Online public reports of quality exist, but little is known about how visitors find reports or about their purpose in visiting. To address this gap, we gathered website analytics data from a national group of online public reports of hospital or physician quality and surveyed real-time visitors to those websites. Websites were recruited from a national group of online public reports of hospital or physician quality. Analytics data were gathered from each website: number of unique visitors, method of arrival for each unique visitor, and search terms resulting in visits. Depending on the website, a survey invitation was launched for unique visitors on landing pages or on pages with quality information. Survey topics included type of respondent (eg, consumer, health care professional), purpose of visit, areas of interest, website experience, and demographics. There were 116,657 unique visitors to the 18 participating websites (1440 unique visitors/month per website), with most unique visitors arriving through search (63.95%, 74,606/116,657). Websites with a higher percent of traffic from search engines garnered more unique visitors (P=.001). The most common search terms were for individual hospitals (23.25%, 27,122/74,606) and website names (19.43%, 22,672/74,606); medical condition terms were uncommon (0.81%, 605/74,606). Survey view rate was 42.48% (49,560/116,657 invited) resulting in 1755 respondents (participation rate=3.6%). There were substantial proportions of consumer (48.43%, 850/1755) and health care professional respondents (31.39%, 551/1755). Across websites, proportions of consumer (21%-71%) and health care professional respondents (16%-48%) varied. Consumers were frequently interested in using the information to choose providers or assess the quality of their provider (52.7%, 225/427); the majority of those choosing a

    This paper introduces an extension of Answer Set Programming called Preference Set Constraint Programming which is a convenient and general formalism to reason with preferences. PSC programming extends Set Constraint Programming introduced by Marek and Remmel (Marek and Remmel 2004) by introducing two types of preference set constraint atoms, measure preference set constraint atoms and pre-ordered preference set constraint atoms, which are extensions of set constraint atoms. We show that the question of whether a PSC program has a preferred stable model is CoNP-complete. We give examples of the uses of the preference set constraint atoms and show that Answer Set Optimization (Brewka, Niemel\\"a, and Truszczynski 2003) and General Preference (Son and Pontelli 2006) can be expressed using preference set constraint atoms.

Methods: Overall, 372 consecutive subjects attending a reference center for HIV treatment in Florence, Italy, were enrolled in the study, from December 2010 to January 2012 (mean age 48 years. A self-report questionnaire was filled in. Patients were defined as “non-adherent” if reporting one of the following criteria:<90% of pills taken in the last month, ≥1 missed dose in the last week, spontaneous treatment interruptions reported, or refill problems in the last 3 months. Gender, age, CD4, HIV-RNA, years of therapy, and type of antiretroviral regimen were analyzed with respect to adherence.

    Documents are being submitted to the Salt Repository Project Office (SRPO) of the US Department of Energy (DOE) by Battelle Memorial Institute's Office of Nuclear Waste Isolation (ONWI) to satisfy milestones of the Salt Repository Project of the Civilian Radioactive Waste Management Program. Some of these documents are being reviewed by multidisciplinary groups of peers to ensure DOE of their adequacy and credibility. Adequacy of documents refers to their ability to meet the standards of the US Nuclear Regulatory Commission, as enunciated in 10 CFR 60, and the requirements of the National Environmental Policy Act and the Nuclear Waste Policy Act of 1982. Credibility of documents refers to the validity of the assumptions, methods, and conclusions, as well as to the completeness of coverage. This report summarizes Argonne's review of ONWI's two-volume draft report entitled Identification of Preferred Sites within the Palo Duro Basin: Vol. 1 - Palo Duro Location A, and Vol. 2 - Palo Duro Location B, dated January 1984. Argonne was requested by DOE to review these documents on January 17 and 24, 1984 (see App. A). The review procedure involved obtaining written comments on the reports from three members of Argonne's core peer review staff and three extramural experts in related research areas. The peer review panel met at Argonne on February 6, 1984, and reviewer comments were integrated into this report by the review session chairman, with the assistance of Argonne's core peer review staff. All of the peer review panelists concurred in the way in which their comments were represented in this report (see App. B). A letter report and a draft of this report were sent to SRPO on February 10, 1984, and April 17, 1984, respectively. 5 references.

    Over 30% of youth and adolescents have overweight or obesity, and health care providers are increasingly discussing weight-based health with these patients. Stigmatizing language in provider-patient communication about obesity is well documented and could be particularly detrimental to youth and adolescents. Although some research has examined preferences for weight-based terminology among adults, no studies have addressed these issues in youth populations. This study represents a preliminary and systematic investigation of weight-based language preferences among adolescents with overweight and obesity enrolled in a summer weight loss camp. Participants (N=50) indicated preferences for weight-based language and emotional responses to words that their family members used in reference to their body weight. Weight neutral terminology ('weight', 'body mass index') were most preferred, although some differences in word preferences emerged by the participants' gender. Boys preferred having their weight described as 'overweight' and 'heavy', while girls preferred the word 'curvy'. A large proportion of participants, particularly girls, reported experiencing sadness, shame, and embarrassment if parents used certain words to describe their body weight, which highlights the importance of considering the emotional impact of weight-based terminology. Providers may consider asking youth and adolescents for their preferences when discussing weight-based health.International Journal of Obesity advance online publication, 4 April 2017; doi:10.1038/ijo.2017.55.

    2014-01-01

    Against a long tradition of childhood realism (Piaget, 1929), A. S. Lillard and J. H. Flavell (1990) found that 3-year-olds prefer to characterize people by their mental states (beliefs, desires, emotions) than by their visible behaviors. In this exploratory study, we extend this finding to a new cohort of 3-year-olds, examine how these preferences change from 3-4 years, and explore relationships with theory of mind and parental mind-mindedness. The results showed a developmental change and a possible cohort difference: at 3 years, children in the sample preferred behavioral descriptions, although by 4 years of age, they preferred mentalistic ones. Interestingly, mentalistic preferences were unrelated to theory of mind or parental mind-mindedness, concurrently or over time. Perspective-taking skills at 3 years, however, predicted an increase in mentalistic responses from 3 years to 4 years. Possible explanations for each finding are discussed.

  13. Medicare's Hospital Compare quality reports appear to have slowed price increases for two major procedures.

    Dor, Avi; Encinosa, William E; Carey, Kathleen

    2015-01-01

    Previous research has found that Hospital Compare, Medicare's public reporting initiative, has had little impact on patient outcomes. However, little is known about the initiative's impact on hospital prices, which may be significant because private insurers are generally well positioned to respond to quality information when negotiating prices with hospitals. We estimated difference-in-differences models of the effects of Hospital Compare quality reporting on transaction prices for two major cardiac procedures, coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI). States that had mandated their own public reporting systems before the implementation of Hospital Compare formed the control group. We found that prices for these procedures continued to increase overall after the initiation of Hospital Compare quality scores, but the rate of increase was significantly lower in states with no quality reporting metrics of their own before Hospital Compare, when compared to the control states (annual rates of increase of 4.4 percent versus 8.7 percent for PCI, and 3.9 percent versus 10.6 percent for CABG, adjusted for overall inflation). This finding implies that Hospital Compare provided leverage to purchasers in moderating price increases, while adding competitive pressures on hospitals. Providing accurate quality information on both hospitals and health plans could benefit consumers.

    Full Text Available Abstract Although current electronic methods of scientific publishing offer increased opportunities for publishing all research studies and describing them in sufficient detail, health research literature still suffers from many shortcomings. These shortcomings seriously undermine the value and utility of the literature and waste scarce resources invested in the research. In recent years there have been several positive steps aimed at improving this situation, such as a strengthening of journals' policies on research publication and the wide requirement to register clinical trials. The EQUATOR (Enhancing the QUAlity and Transparency Of health Research Network is an international initiative set up to advance high quality reporting of health research studies; it promotes good reporting practices including the wider implementation of reporting guidelines. EQUATOR provides free online resources http://www.equator-network.org supported by education and training activities and assists in the development of robust reporting guidelines. This paper outlines EQUATOR's goals and activities and offers suggestions for organizations and individuals involved in health research on how to strengthen research reporting.

    Departing from the traditional approach to modeling an agent who finds it difficult to make clear-cut comparisons between alternatives, we introduce the notion of graded preferences: Given two alternatives, the agent reports a number between 0 and 1, which reflects her inclination to prefer the first option over the second or, put differently, how confident she is about the superiority of the first one. In the classical framework of uncertainty, we derive a representation of a graded preferen...

    Advertising plays a major role in smoking behavior and forming brand preferences. Additionally, the most advertised tobacco brands have also been the most preferred. Maintaining brand loyalty in Latin America remains a priority for the tobacco industry. The purpose of this study was to explore tobacco brand preference trends from 2003 to 2006, and explore marketing and advertising factors that might be associated with these trends. Data for this study came from Mexican adolescents residing in cities that participated in the Global Youth Tobacco Survey in both 2003 and 2006 and reported smoking either Marlboro or Camel cigarettes in the past 30 days. Respondents reported the brand name of their preferred cigarette during the past 30 days. Multivariate regression analysis was used to determine differences by brand preference and exposure to tobacco marketing and advertising, which was assessed using six items. In 2003, most adolescents preferred Marlboro. By 2006, older boys preferred Camel cigarettes to Marlboro, while girls' preference for Camel was similar to their preference for Marlboro. Adolescents that preferred Camel cigarettes in 2003 also reported greater exposure to tobacco marketing and advertising. Findings indicate that there are ongoing shifts in youth brand preference in Mexico, and that these shifts might be related to marketing and advertising practices. There is an ongoing need for monitoring marketing and advertising practices in an effort to protect adolescents from tobacco company exploits.

    In 2013, a rubella outbreak was observed in Japan, Romania, and Poland. The outbreak in Japan was accompanied by an increase of measles reports, especially from a region where measles is highly controlled. This was attributed to the adult populations affected by this rubella outbreak, similarity of clinical signs between rubella and measles, sufficiently small impact of measles outbreaks from neighboring nations, and elimination levels of measles endemicity. Current and future concerns for measles control are discussed.

    2016-01-01

    Reports describing a rapid increase in the cystic volume of anaplastic astrocytoma (AA) in a short time frame are rare. The present study reports the case of a 68-year-old male who was admitted to the No. 9 People's Hospital, Shanghai Jiaotong University School of Medicine (Shanghai, China), with a small cystic brain lesion and positive immunological testing for cysticercosis. Head magnetic resonance imaging (MRI) showed a cystic lesion, 6 mm in diameter, in the left frontal lobe. Neurocysticercosis was suspected and the patient was treated with a clinical trial of albendazole and steroids. A period of 25 days later, the patient's condition had deteriorated, and MRI revealed a cystic lesion in the left frontal lobe; thereafter, the cystic lesion was removed and a diagnosis of AA was established. The tumor was soft, ivory white and gelatinous due to myxoid degeneration. In this case, tumor-related angiogenesis and microvascular extravasation (blood-brain barrier disruption) may have been the main cause of the rapid increase in the cystic volume in such a short time frame. The similarity of the glioma and cysticercus antigens may have been the cause of the positive reactions in the cystic fluid. The present study reports the rare occurrence of a rapid increase of cystic volume and potential diagnostic difficulties. PMID:27698865

    In patients with Charcot spine, a loss of normal feedback response from the insensate spine results in spinal neuropathy. Increasing deformity, which can manifest as sitting imbalance, crepitus, or increased back pain, can result. We present the case of a patient with a high-thoracic spinal cord injury (SCI) who subsequently developed a Charcot joint at the T10-11 level that resulted in a dramatic increase in previously controlled spasticity after fracture of an existing baclofen catheter. The 68-year-old man with T4 paraplegia presented with increasing baclofen requirements and radiographic evidence of fracture of the intrathecal baclofen catheter with an associated Charcot joint with extensive bony destruction. The neuropathic spinal arthropathy caused mechanical baclofen catheter malfunction and resulting increased spasticity. The patient was found to have transected both his spinal cord and the baclofen catheter. Treatment consisted of removal of the catheter and stabilization with long-segment instrumentation and fusion from T6 to L2. Follow-up radiographs obtained a year and a half after surgery showed no evidence of hardware failure or significant malalignment. The patient has experienced resolution of symptoms and does not require oral or intrathecal baclofen. This is the only reported case of a Charcot spine causing intrathecal catheter fracture, leading to increased spasticity. This noteworthy case suggests that late spinal instability should be considered in the setting of SCI and increased spasticity.

    Objective To assess the impact of a 2007 cigarette tax increase from 110% to 140% of the price to the retailer on cigarette price and consumption among Mexican smokers, including efforts to offset price increases. Methods Data were analysed from the 2006 and 2007 administrations of the International Tobacco Control (ITC) Policy Evaluation Survey in Mexico, which is a population-based cohort of adult smokers. Self-reported price of last cigarette purchase, place of last purchase, preferred brand, daily consumption and quit behaviour were assessed at baseline and follow-up. Results Self-reported cigarette prices increased by 12.7% after the tax increase, with prices for international brands increasing more than for national brands (13.5% vs 8.7%, respectively). Although the tax increases were not fully passed onto consumers particularly on national brands, no evidence was found for smokers changing behaviour to offset price increases. Consistent declines in consumption across groups defined by sociodemographic and smoking-related psychosocial variables suggest a relatively uniform impact of the tax increase across subpopulations. However, decreased consumption appeared limited to people who smoked relatively more cigarettes a day (>5 cigarettes/day). Average daily consumption among lighter smokers did not significantly decline. A total of 13% (n=98) of the sample reported being quit for a month or more at follow-up. In multivariate models, lighter smokers were more likely than heavier smokers to be quit. Conclusions Results suggest that the 2007 tax increase was passed on to consumers, whose consumption generally declined. Since no other tobacco control policies or programmes were implemented during the period analysed, the tax increase appears likely to have decreased consumption. PMID:20870740

    Estradiol changes associated with the menstrual cycle have a great impact on brain activation. δ frequency mainly appears during normal sleep status or brain injury diseases, including encephalitis and mental confusion. The current case report presents a 51-year-old female with prolonged menstruation and increased menstrual blood volume whose electroencephalogram (EEG) recording demonstrated a rare generalized 3 Hz δ frequency band in the waking status. The patient had been suffering from heart palpitations and dizziness for 6 months and was receiving treatment in the Department of Neurology (Second Xiangya Hospital). The individual had been experiencing prolonged menstruation and increased menstrual blood volume for 6 years. Gynecologial examination revealed secondary anemia and hysteromyoma. Hemoglobin levels were decreased to 69 g/l. Physical and neurological examinations, and computed tomography results appeared normal. The EEG recording indicated a generalized 3 Hz δ frequency band with 30-80 μV power and a long-range δ frequency band when the patient was hyperventilating. The prolonged menstruation and increased menstrual blood volume may have induced the generalized δ frequency without brain injury. To the best of our knowledge, this is the first formal case report of prolonged menstruation and increased menstrual blood volume with the abnormality of δ EEG power.

    2017-01-01

    Social Transmission of Food Preference (STFP) is a single trial non-aversive learning task that is used for testing non-spatial memory. This task relies on an accurate estimate of a change in food preference of the animals following social demonstration of a novel flavor. Conventionally this is done by providing two flavors of powdered food and later estimating the amount of food consumed for each of these flavors in a defined period of time. This is achieved through a careful measurement of leftover food for each of these flavors. However, in mice, only a small (~1 g) amount of food is consumed making the weight estimates error prone and thereby limiting the sensitivity of the paradigm. Using multiplexed video tracking, we show that the pattern of consumption can be used as a reliable reporter of memory retention in this task. In our current study, we use this as a measure and show that the preference for the demonstrated flavor significantly increases following demonstration and the retention of this change in preference during remote testing is flavor specific. Further, we report a modified experimental design for performing STFP that allows testing of change in preference among two flavors simultaneously. Using this paradigm, we show that during remote testing for thyme and basil demonstrated flavors, only basil demonstrated mice retain the change in preference while thyme demonstrated mice do not.

The main results of a mixed proportional hazard competing risks model are that placed refugees react to high regional unemployment...... and lack of a local immigrant population by migrating to large municipalities. Lack of local fellow countrymen, however, increases the exit rate to medium-sized as well as large municipalities. This finding is likely to be a result of the dispersal policy.

This article examines symptom persistence, incidence and prevalence 20 years on. In 2000-2003 and 2011-2012, a 63-item symptom checklist was administered to 697 veterans and 659 comparison group. Symptomatology was compared using log-binomial regression. Both veterans and comparison group reported significantly increased prevalence (3-52%) over time in more than half the symptoms, with a similar overall rate of increase. Half the symptoms had higher incidence (risk-ratios ranged 1.43-1.50) and a quarter were more persistent (risk-ratios ranged 1.12-1.20) in veterans than the comparison group. Symptomatology increased in both groups over time, but persisted to a similar extent and had higher incidence among veterans than the comparison group. The gap in symptom prevalence between the two groups remained unchanged. These findings suggest enduring health consequences of Gulf War service. © 2015 Commonwealth of Australia.

    Full Text Available Abstract Background Interventions designed to increase workplace physical activity may not automatically reduce high volumes of sitting, a behaviour independently linked to chronic diseases such as obesity and type II diabetes. This study compared the impact two different walking strategies had on step counts and reported sitting times. Methods Participants were white-collar university employees (n = 179; age 41.3 ± 10.1 years; 141 women, who volunteered and undertook a standardised ten-week intervention at three sites. Pre-intervention step counts (Yamax SW-200 and self-reported sitting times were measured over five consecutive workdays. Using pre-intervention step counts, employees at each site were randomly allocated to a control group (n = 60; maintain normal behaviour, a route-based walking group (n = 60; at least 10 minutes sustained walking each workday or an incidental walking group (n = 59; walking in workday tasks. Workday step counts and reported sitting times were re-assessed at the beginning, mid- and endpoint of intervention and group mean± SD steps/day and reported sitting times for pre-intervention and intervention measurement points compared using a mixed factorial ANOVA; paired sample-t-tests were used for follow-up, simple effect analyses. Results A significant interactive effect (F = 3.5; p t = 3.9, p t = 2.5, p Conclusion Compared to controls, both route and incidental walking increased physical activity in white-collar employees. Our data suggests that workplace walking, particularly through incidental movement, also has the potential to decrease employee sitting times, but there is a need for on-going research using concurrent and objective measures of sitting, standing and walking.

    This report presents the questions and responses to a nationwide survey taken June 2016 to track preferences of US residents concerning the environment, energy, and radioactive waste management. A focus of the 2016 survey is public perceptions on different options for managing spent nuclear fuel, including on-site storage, interim storage, deep boreholes, general purpose geologic repositories, and geologic repositories for only defense-related waste. Highlights of the survey results include the following: (1) public attention to the 2011 accident and subsequent cleanup at the Fukushima nuclear facility continues to influence the perceived balance of risk and benefit for nuclear energy; (2) the incident at the Waste Isolation Pilot Plant in 2014 could influence future public support for nuclear waste management; (3) public knowledge about US nuclear waste management policies has remined higher than seen prior to the Fukushima nuclear accident and submittal of the Yucca Mountain application; (6) support for a mined disposal facility is higher than for deep borehole disposal, building one more interim storage facilities, or continued on-site storage of spent nuclear fuel; (7) support for a repository that comingles commercial and defense related waste is higher than for a repository for only defense related waste; (8) the public’s level of trust accorded to the National Academies, university scientists, and local emergency responders is the highest and the level trust accorded to advocacy organizations, public utilities, and local/national press is the lowest; and (9) the public is willing to serve on citizens panels but, in general, will only modestly engage in issues related to radioactive waste management.

    Full Text Available Studies for acupuncture that has been used as a medical therapeutic method for thousands of years in Far East, is being increased in Western world. In parallel to this increase, there raised several methodologic problems. The most important one of these is the choice of control procedure. If a valid and credible control method has not been chosen, these ‘placebo acupuncture’ or ‘sham acupuncture’ controls could make a negative impact on the study results. In this paper, these different sham acupuncture methods are dis-cussed to find an optimal control procedure. The second major problem which was encountered with acupuncture studies is related with the reporting of interventions. Like CONSORT checklist in conventional medicine, STRICTA recommendations list is prepared for the controlled acupuncture trials. In conclusion, to choose a valid and credible control procedure and to follow CONSORT checklist and STRICTA recommendations will improve the quality of acupuncture studies.

  15. Jogging Therapy for Hikikomori Social Withdrawal and Increased Cerebral Hemodynamics: A Case Report.

    Severe social withdrawal, called hikikomori, has drawn increased public attention. However, an optimal clinical approach and strategy of treatment has not been well established. Here, we report a case of hikikomori for which an exercise intervention using jogging therapy was effective, showing cerebral hemodynamic improvement. The patient was a 20 year old Japanese male who was hospitalized in order to evaluate and treat severe social withdrawal. Although depressive and anxiety symptoms partially subsided with sertraline alone, social withdrawal persisted due to a lack of self confidence. With his consent, we implemented exercise therapy with 30 minutes of jogging three times a week for three months. We did not change the pharmacotherapy, and his social withdrawal remarkably improved with continuous jogging exercise. Using near infrared spectroscopy to evaluate hemodynamic alteration, bilateral temporal hemodynamics considerably increased after the three-month jogging therapy. Regarding exercise therapy for mental illness, numerous studies have reported the effectiveness of exercise therapy for major depression. This case implied, however, that the applicability of exercise therapy is not limited to major depressive disorder. Jogging therapy may contribute to reinforcing self confidence associated with "resilience" in conjunction with neurophysiological modulation of neural networks.

  16. Pregnancy-associated breast cancer and increased risk of pregnancy-associated recurrence: a case report

    Full Text Available Abstract Introduction Pregnancy-associated breast cancer refers to breast cancer diagnosed during pregnancy, lactation, or within twelve months postpartum. Recent studies suggest that, when matched for age and stage, the prognosis of pregnancy-associated breast cancer is comparable to non-pregnancy-associated breast cancer. However, the risk for breast cancer recurrence associated with subsequent pregnancies in this population is not clear. Case presentation We describe the case of a Caucasian woman who was initially treated for pregnancy-associated breast cancer at age 23, three months after the birth of her third child. She underwent a total mastectomy with axillary node dissection, followed by chemotherapy and hormonal therapy. Ten years later, when the patient was 24 weeks pregnant with her fourth child, she presented with an ipsilateral chest wall recurrence of breast cancer. To the best of our knowledge, this represents the first reported case of a pregnancy-associated recurrence in a patient previously treated for pregnancy-associated breast cancer. Conclusion The case described here is the first report of a second occurrence of pregnancy-associated breast cancer. This case raises the possibility that pregnancy may represent a unique trigger for breast malignancy in a specific cohort of women. Although there is data showing no increase in the risk of recurrence for women who become pregnant after breast cancer treatment, pregnancy-associated breast cancer may be a distinct clinical category where subsequent pregnancies after treatment may confer an increased risk of recurrent disease.

  17. Preferences for Internet-Based Mental Health Interventions in an Adult Online Sample: Findings From an Online Community Survey.

    Despite extensive evidence that Internet interventions are effective in treating mental health problems, uptake of Internet programs is suboptimal. It may be possible to make Internet interventions more accessible and acceptable through better understanding of community preferences for delivery of online programs. This study aimed to assess community preferences for components, duration, frequency, modality, and setting of Internet interventions for mental health problems. A community-based online sample of 438 Australian adults was recruited using social media advertising and administered an online survey on preferences for delivery of Internet interventions, along with scales assessing potential correlates of these preferences. Participants reported a preference for briefer sessions, although they recognized a trade-off between duration and frequency of delivery. No clear preference for the modality of delivery emerged, although a clear majority preferred tailored programs. Participants preferred to access programs through a computer rather than a mobile device. Although most participants reported that they would seek help for a mental health problem, more participants had a preference for face-to-face sources only than online programs only. Younger, female, and more educated participants were significantly more likely to prefer Internet delivery. Adults in the community have a preference for Internet interventions with short modules that are tailored to individual needs. Individuals who are reluctant to seek face-to-face help may also avoid Internet interventions, suggesting that better implementation of existing Internet programs requires increasing acceptance of Internet interventions and identifying specific subgroups who may be resistant to seeking help.

    Full Text Available Abstract Allergic reaction to insulin is known to be associated with eosinophilia and hyper IgE. Recent report showed that eosinophilia is related with the increased synthesis of galectin-9 (GAL-9 and osteopontin (OPN. Here, we examined plasma levels of GAL-9 and OPN first time in a case of 65-year old patient with insulin allergy. Insulin aspart & insulin aspart 30 mix were given to the patient and an elevation of the eosinophil count (8440/μl, 17.6 fold and a moderate increase of IgE (501 U/ml, reference range: 10-350 U/ml, eotaxin-3 (168 pg/ml, 2 fold, histamine (0.95 ng/ml, 5.3 fold were found 33 days later. The plasma levels of GAL-9 and OPN were 22.5 and 1.7 fold higher than the cut-off point, respectively. After one month cessation of insulin therapy, elevations of the eosinophil count (3,480/μl; 7.3 fold, and OPN (1.4 fold still occurred but the GAL-9 levels became normal. Therefore, we noted the increases of GAL-9 and OPN in plasma for the first time in a patient with insulin allergy and propose that GAL-9 reflects the conditions of allergy more accurately.

  4. Increased bias to report heat or pain following emotional priming of pain-related fear.

    Kirwilliam, S S; Derbyshire, S W G

    2008-07-01

    Emotional and attentional factors have been identified to play a significant role in modulating pain perception with negative emotions increasing pain sensitivity. Recent studies suggest that fearful images may activate the attentional components of fear driven behaviours and facilitate an attentional bias or sensitivity toward noxious stimuli. The current investigation examines whether priming of pain-related fear will affect performance by increasing sensitivity to punctuate heat stimuli. A modified version of the visual dot probe task was employed to provide priming of pain-related fear and a heat detection task was used to measure the effects of priming on sensitivity. The results indicated a significant facilitation of heat and pain perception at varying temperatures following emotional priming. In particular, there was an increase in the bias toward reporting a heat stimulus following emotional priming. The findings emphasise the efficacy of the visual dot probe task as a method of priming and provide a possible method for probing hypervigilance in chronic pain patients.

  5. Adult Neuroblastoma Complicated by Increased Intracranial Pressure: A Case Report and Review of the Literature

    Full Text Available Neuroblastoma is the third most commonly occurring malignancy of the pediatric population, although it is extremely rare in the adult population. In adults, neuroblastoma is often metastatic and portends an extremely poor overall survival. Our case report documents metastatic neuroblastoma occurring in a healthy 29-year-old woman whose course was complicated by an unusual presentation of elevated intracranial pressures. The patient was treated with systemic chemotherapy, I131 metaiodobenzylguanidine (MIBG radiotherapy, and autologous stem cell transplant (SCT. Unfortunately the patient’s response to therapy was limited and she subsequently died. We aim to review neuroblastoma in the context of increased intracranial pressure and the limited data of neuroblastoma occurring in the adult population, along with proposed treatment options.

  6. Increasing the biomass production of short rotation coppice forests. Progress report

    Progress is reported in research to increase biomass yields from coppice forests by admixing the nitrogen fixing tree Alnus glutinosa to plantations of Plantanus occidentalis and Liquidambar styraciflua. Plantations to compare growth rates of pure and mixed plots of the three species have been established on two sites in Georgia. Locations were selected on the basis of physiographic province (Piedmont and Coastal Plain) on soils which probably will be available for short rotation forestry. Propagation techniques for mass-cloning Platanus occidentalis using single buds and internodes of dormant or active twigs from young trees were developed. Tissue culture procedures were used to induce bud and root formation in callus cultures of Robinia and Gleditsia. Research dealing with fluctuations in starch and sugar levels in coppiced root systems of sycamore during the winter is reported. Total available carbohydrates ranged from 15 to 26 percent of root dry weight and starch to sugar conversion was detected. However, more starch disappeared than could be accounted for by the concomitant rise of sugar levels. There were some differences between annually coppiced root systems and those cut every two years.

    2017-06-01

    Muscle dysfunction is very common following musculoskeletal injury. There is very little evidence to suggest that muscle function may be positively impacted by soft tissue interventions, such as dry needling. The purpose of this case report is to describe the immediate effect of dry needling on muscle thickness in a subject after shoulder surgery. A 22 year-old competitive gymnast presented seven months post shoulder surgery with significant impairments and functional limitations. Previous physical therapy focused on restoration of range of motion and strength using general exercise interventions, but the subject had persistent tightness and weakness of musculature of the shoulder complex. A subject-specific physical therapy program including manual physical therapy resulted in significant initial improvement, but lack of flexibility and weakness of the rotator cuff limited progress. Dry needling was used to address persistent myofascial trigger points. Immediately after dry needling the infraspinatus, the muscle's thickness was significantly improved as measured by rehabilitative ultrasound imaging. There was a corresponding increase in force production of external rotation at 90 degrees of abduction. Minimal research exists that validates the potential of dry needling on muscle function, as assessed by muscle thickness measured using rehabilitative ultrasound imaging. The results of this case report suggest that dry needling contributed to improvement in muscle thickness and strength in a subject with muscle dysfunction following an injury. 4.

    Full Text Available Abstract Background Hypertrophic cardiomyopathy is a frequent manifestation in Fabry disease (FD - an X-linked lysosomal storage disorder caused by reduced activity of the enzyme α-galactosidase A. In FD an elevation of specific cardiac biomarkers, such as cardiac troponin I (cTNI has been reported in case of clinical manifestation suggestive of myocardial ischemia. In diagnosing acute myocardial infarction cTNI is considered the most reliable parameter. Case Presentation In the referred case we present a 59 years old female patient with the diagnosis of FD presenting with persistently increased cTNI level (lowest value 0.46 ng/ml, highest value 0.69 ng/ml; normal range Conclusions Our case report demonstrates a persistent cTNI release in FD with cardiac involvement. Proving the persistence in a symptom free interval, it might be related to a direct damage of myocytes. In FD cTNI could serve as a beneficial long term parameter providing new perspectives for screening strategies.

    the methodological issues extend to larger groups that form endogenously (e.g., families, committees, communities). Preferences over social risk can be closely approximated by individual risk attitudes when subjects have no information about the risk preferences of other group members. We find no evidence......We elicit individual preferences over social risk. We identify the extent to which these preferences are correlated with preferences over individual risk and the well-being of others. We examine these preferences in the context of laboratory experiments over small, anonymous groups, although...... that subjects systematically reveal different risk attitudes in a social setting with no prior knowledge about the risk preferences of others compared to when they solely bear the consequences of the decision. However, we also find that subjects are significantly more risk averse when they know the risk...

    Why do we like the music we do? Research has shown that musical preferences and personality are linked, yet little is known about other influences on preferences such as cognitive styles. To address this gap, we investigated how individual differences in musical preferences are explained by the empathizing-systemizing (E-S) theory. Study 1 examined the links between empathy and musical preferences across four samples. By reporting their preferential reactions to musical stimuli, samples 1 and 2 (Ns = 2,178 and 891) indicated their preferences for music from 26 different genres, and samples 3 and 4 (Ns = 747 and 320) indicated their preferences for music from only a single genre (rock or jazz). Results across samples showed that empathy levels are linked to preferences even within genres and account for significant proportions of variance in preferences over and above personality traits for various music-preference dimensions. Study 2 (N = 353) replicated and extended these findings by investigating how musical preferences are differentiated by E-S cognitive styles (i.e., 'brain types'). Those who are type E (bias towards empathizing) preferred music on the Mellow dimension (R&B/soul, adult contemporary, soft rock genres) compared to type S (bias towards systemizing) who preferred music on the Intense dimension (punk, heavy metal, and hard rock). Analyses of fine-grained psychological and sonic attributes in the music revealed that type E individuals preferred music that featured low arousal (gentle, warm, and sensual attributes), negative valence (depressing and sad), and emotional depth (poetic, relaxing, and thoughtful), while type S preferred music that featured high arousal (strong, tense, and thrilling), and aspects of positive valence (animated) and cerebral depth (complexity). The application of these findings for clinicians, interventions, and those on the autism spectrum (largely type S or extreme type S) are discussed.

    Eight rats responded on concurrent Variable-Ratio 20 Extinction schedules for food reinforcement. The assignment of variable-ratio reinforcement to a left or right lever varied randomly following each reinforcer, and was cued by illumination of a stimulus light above that lever. Postreinforcement preference levels decreased substantially and reliably over time when the lever that just delivered reinforcement was now in extinction; however, if that lever was once again associated with variable ratio, this decrease in same-lever preference tended to be small, and for some subjects, not in evidence. The changes in preference level to the extinction lever were well described by a modified version of Killeen, Hanson, and Osborne's (1978) induction model. Consistent with this model's attribution of preference change to induction, we attribute preference change in this report to a brief period of reinforcer-induced arousal that energizes responding to the lever that delivered the last reinforcer. After a few seconds, this induced responding diminishes, and the operant responding that remains comes under the control of the stimulus light cuing the lever providing variable-ratio reinforcement.

    2015-09-01

    The learning style preferences of general surgery residents have been previously reported; there is evidence that residents who prefer read/write learning styles perform better on the American Board of Surgery In-Training Examination (ABSITE). However, little is known regarding the learning style preferences of applicants to general surgery residency and their impact on educational outcomes. In this study, the preferred learning styles of surgical residency applicants were determined. We hypothesized that applicant rank data are associated with specific learning style preferences. The Fleming VARK learning styles inventory was offered to all general surgery residency applicants that were interviewed at a university hospital-based program. The VARK model categorizes learners as visual (V), aural (A), read/write (R), kinesthetic (K), or multimodal (MM). Responses on the inventory were scored to determine the preferred learning style for each applicant. Applicant data, including United States Medical Licensing Examination (USMLE) scores, class rank, interview score, and overall final applicant ranking, were examined for association with preferred learning styles. Sixty-seven applicants were interviewed. Five applicants were excluded due to not completing the VARK inventory or having incomplete applicant data. The remaining 62 applicants (92%) were included for analysis. Most applicants (57%) had a multimodal preference. Sixty-nine percent of all applicants had some degree of preference for kinesthetic learning. There were statistically significant differences between applicants of different learning styles in terms of USMLE step 1 scores (P = 0.001) and USMLE step 2 clinical knowledge scores (P = 0.01), but not for class ranks (P = 0.27), interview scores (P = 0.20), or final ranks (P = 0.14). Multiple comparison analysis demonstrated that applicants with aural preferences had higher USMLE 1 scores (233.2) than those with kinesthetic (211.8, P = 0.005) or multimodal

    We study the problem of locating a single facility on a real line based on the reports of self-interested agents, when agents have double-peaked preferences, with the peaks being on opposite sides of their locations. We observe that double-peaked preferences capture real-life scenarios and thus...... complement the well-studied notion of single-peaked preferences. We mainly focus on the case where peaks are equidistant from the agents’ locations and discuss how our results extend to more general settings. We show that most of the results for single-peaked preferences do not directly apply to this setting...

    2008-05-01

    With the increasing stress on ocean and coastal resources, ocean resource management will require greater capacity in terms of people, institutions, technology and tools. Successful capacity-building efforts address the needs of a specific locale or region and include plans to maintain and expand capacity after the project ends. In 2008, the US National Research Council published a report that assesses past and current capacity-building efforts to identify barriers to effective management of coastal and marine resources. The report recommends ways that governments and organizations can strengthen marine conservation and management capacity. Capacity building programs instill the tools, knowledge, skills, and attitudes that address: ecosystem function and change; processes of governance that influence societal and ecosystem change; and assembling and managing interdisciplinary teams. Programs require efforts beyond traditional sector-by-sector planning because marine ecosystems range from the open ocean to coastal waters and land use practices. Collaboration among sectors, scaling from local community-based management to international ocean policies, and ranging from inland to offshore areas, will be required to establish coordinated and efficient governance of ocean and coastal ecosystems. Barriers Most capacity building activities have been initiated to address particular issues such as overfishing or coral reef degradation, or they target a particular region or country facing threats to their marine resources. This fragmentation inhibits the sharing of information and experience and makes it more difficult to design and implement management approaches at appropriate scales. Additional barriers that have limited the effectiveness of capacity building programs include: lack of an adequate needs assessment prior to program design and implementation; exclusion of targeted populations in decision- making efforts; mismanagement, corruption, or both; incomplete or

    Americans have access to medical information from a variety of sources, including readily accessible information on the Internet. As the American population's trust in online sources changes over time, it is possible that their cancer information-seeking preferences and behaviors also may change. The purpose of this study is to assess longitudinal trends in cancer information-seeking preferences and behaviors based on data collected in 3 Health Information National Trends Surveys (HINTS) administered by the National Cancer Institute. This is a retrospective secondary data analysis that compares the survey results of HINTS administered in 2003, 2005, and 2007. Frequency distribution, percentages, and variability were investigated, and findings were presented by age group, type of information source, and self-reported level of trust in medical information obtained. The analysis demonstrates trends in patient cancer information-seeking preferences and behaviors between 2003 and 2007. With each survey, for example, the library gained increasing popularity as a source for cancer information. In 2007, survey participants viewed the library as their primary reference, followed by the Internet. On the other hand, views of health care providers as a primary information source decreased from 2003 to 2007. Older generations appear to rely on Internet sources more often than they rely on health care providers for cancer information. Thus, it is important to ensure this patient group and all patients are accessing reliable resources when they seek cancer information, regardless of the source.

    One hundred seventy-eight male and female undergraduates completed the Eysenck Personality Inventory and indicated their risk preference assessed under the assumptions of Coombs' portfolio theory. Extraverts preferred higher risk significantly more than did introverts, and also showed significantly greater risk preference change as expected value increased. It was suggested that a theoretically defensible selection of both personality variables and a risk assessment model may lead to greater personality-risk predictability.

  1. Increasing the Efficiency on Producing Radiology Reports for Breast Cancer Diagnosis by Means of Structured Reports. A Comparative Study.

    Radiology reports are commonly written on free-text using voice recognition devices. Structured reports (SR) have a high potential but they are usually considered more difficult to fill-in so their adoption in clinical practice leads to a lower efficiency. However, some studies have demonstrated that in some cases, producing SRs may require shorter time than plain-text ones. This work focuses on the definition and demonstration of a methodology to evaluate the productivity of software tools for producing radiology reports. A set of SRs for breast cancer diagnosis based on BI-RADS have been developed using this method. An analysis of their efficiency with respect to free-text reports has been performed. The methodology proposed compares the Elapsed Time (ET) on a set of radiological reports. Free-text reports are produced with the speech recognition devices used in the clinical practice. Structured reports are generated using a web application generated with TRENCADIS framework. A team of six radiologists with three different levels of experience in the breast cancer diagnosis was recruited. These radiologists performed the evaluation, each one introducing 50 reports for mammography, 50 for ultrasound scan and 50 for MRI using both approaches. Also, the Relative Efficiency (REF) was computed for each report, dividing the ET of both methods. We applied the T-Student (T-S) test to compare the ETs and the ANOVA test to compare the REFs. Both tests were computed using the SPSS software. The study produced three DICOM-SR templates for Breast Cancer Diagnosis on mammography, ultrasound and MRI, using RADLEX terms based on BIRADs 5th edition. The T-S test on radiologists with high or intermediate profile, showed that the difference between the ET was only statistically significant for mammography and ultrasound. The ANOVA test performed grouping the REF by modalities, indicated that there were no significant differences between mammograms and ultrasound scans, but both

  2. The allometry of prey preferences.

    Full Text Available The distribution of weak and strong non-linear feeding interactions (i.e., functional responses across the links of complex food webs is critically important for their stability. While empirical advances have unravelled constraints on single-prey functional responses, their validity in the context of complex food webs where most predators have multiple prey remain uncertain. In this study, we present conceptual evidence for the invalidity of strictly density-dependent consumption as the null model in multi-prey experiments. Instead, we employ two-prey functional responses parameterised with allometric scaling relationships of the functional response parameters that were derived from a previous single-prey functional response study as novel null models. Our experiments included predators of different sizes from two taxonomical groups (wolf spiders and ground beetles simultaneously preying on one small and one large prey species. We define compliance with the null model predictions (based on two independent single-prey functional responses as passive preferences or passive switching, and deviations from the null model as active preferences or active switching. Our results indicate active and passive preferences for the larger prey by predators that are at least twice the size of the larger prey. Moreover, our approach revealed that active preferences increased significantly with the predator-prey body-mass ratio. Together with prior allometric scaling relationships of functional response parameters, this preference allometry may allow estimating the distribution of functional response parameters across the myriads of interactions in natural ecosystems.

    Full Text Available BACKGROUND: Seasonal variations in mood and behaviour, termed seasonality, are commonly reported in the general population. As a part of a large cross-sectional health survey in Hordaland, Norway, we investigated the relationship between seasonality, objective health measurements and health behaviours. METHODOLOGY/PRINCIPAL FINDINGS: A total of 11,545 subjects between 40-44 years old participated, completing the Global Seasonality Score, measuring seasonality. Waist/hip circumference, BMI and blood pressure were measured, and blood samples were analyzed for total cholesterol, HDL cholesterol, triglycerides and glucose. Subjects also completed a questionnaire on miscellaneous health behaviours (exercise, smoking, alcohol consumption. Hierarchical linear regression analyses were used to investigate associations between seasonality and objective health measurements, while binary logistic regression was used for analysing associations between seasonality and health behaviours. Analyses were adjusted for sociodemographic factors, month of questionnaire completion and sleep duration. Seasonality was positively associated with high waist-hip-ratio, BMI, triglyceride levels, and in men high total cholesterol. Seasonality was negatively associated with HDL cholesterol. In women seasonality was negatively associated with prevalence of exercise and positively associated with daily cigarette smoking. CONCLUSIONS/SIGNIFICANCE: High seasonality was associated with objective health risk factors and in women also with health behaviours associated with an increased risk for cardiovascular disease.

    Repeated local administration of ethanol (EtOH) sensitized the posterior ventral tegmental area (pVTA) to the local dopamine (DA)-stimulating effects of EtOH. Chronic alcohol drinking increased nucleus accumbens (NAC) DA transmission and pVTA glutamate transmission in alcohol-preferring (P) rats. The objectives of the present study were to determine the effects of chronic alcohol drinking by P rats on the (a) sensitivity and response of the pVTA DA neurons to the DA-stimulating actions of EtOH, and (b) negative feedback control of DA (via D2 auto-receptors) and glutamate (via group II mGlu auto-receptors) release in the pVTA. EtOH (50 or 150 mg%) or the D2/3 receptor antagonist sulpiride (100 or 200 μM) was microinjected into the pVTA while DA was sampled with microdialysis in the NAC shell (NACsh). The mGluR2/3 antagonist LY341495 (1 or 10 μM) was perfused through the pVTA via reverse microdialysis and local extracellular glutamate and DA levels were measured. EtOH produced a more robust increase of NACsh DA in the 'EtOH' than 'Water' groups (e.g., 150 mg% EtOH: to ∼ 210 vs 150% of baseline). In contrast, sulpiride increased DA release in the NACsh more in the 'Water' than 'EtOH' groups (e.g., 200 μM sulpiride: to ∼ 190-240 vs 150-160% of baseline). LY341495 (at 10 μM) increased extracellular glutamate and DA levels in the 'Water' (to ∼ 150-180% and 180-230% of baseline, respectively) but not the 'EtOH' groups. These results indicate that alcohol drinking enhanced the DA-stimulating effects of EtOH, and attenuated the functional activities of D2 auto-receptors and group II mGluRs within the pVTA.

    Full Text Available European integration is supported through important financial resources in order to sustain the investment effort for aligning the business infrastructure and increase in the business competitiveness in order to fulfill the European Union standards. The financial management, a basic component of the general management, has as scope to realize complex financial analysis in order to substantiate the decisions for investments and financing which should ensure the maximization of results, ensuring also the elaboration of the project budget as an essential document in the identification of the needs for resources and for obtaining the non-reimbursable financial sources. An essential role in the investment decision making, having as support European funding, is realized by the financial-accounting reporting documents such as balance sheet, profit and loss account, table of the treasury flows, which together with a realistic established actualization rate ensures the relevance and efficiency of the financial indicators: Net present Value(NPV, Internal Rate of Return(IRR, the investment recovery period, the benefit/cost ratio. This study has as its goal to realize a critical analysis over the main simulation methods and techniques for forecasting annual return based on its growth rate, which should ensure the success of the implementation and operation of an investment realized through European structural funds respecting also the requirements for minimization of risks. In this research it is shown the importance of proper generation/modeling of the annual turnover in an investment project. Several methods were presented and case study was realized. Since the annual turnover constitutes the basis for the entire financial analysis it is very important that a realistic growth rate is used. Otherwise the provisions within the financial analysis of the investment (including CBA, the project implementation strategy and later the plan for the utilization of

    Our study explores the role of victims' consultation with others about whether or not to report their rape to police. Three groups were observed within this sample of 435 rape victims from a national telephone household probability sample of women: those who did not consult with anyone about reporting (n = 364), those who consulted with someone and were encouraged to report to police (n = 40), and those who consulted with someone and were not encouraged to report (n = 31). Descriptive analyses indicated that the encouraged group was more likely to report to police than either of the other two groups (which did not differ from each other). Because there were no differences between the two consulting groups on demographic or rape-related variables, they were combined in subsequent analyses. Consulting with others about whether to report, peri-traumatic fear of injury or death, assault perpetration by a stranger, and concerns about contracting a sexually transmitted disease were significant predictors of reporting to police after controlling for other significant predictors in a multivariate regression analysis. Implications of these findings are discussed, including the benefits and consequences of formal rape reporting for victims, and the role that disclosure recipients may have in assisting victims post-rape (e.g., encouragement of reporting, emotional support).

    Risk taking is central to human activity. Consequently, it lies at the focal point of behavioral sciences such as neuroscience, economics, and finance. Many influential models from these sciences assume that financial risk preferences form a stable trait. Is this assumption justified and, if not, what causes the appetite for risk to fluctuate? We have previously found that traders experience a sustained increase in the stress hormone cortisol when the amount of uncertainty, in the form of market volatility, increases. Here we ask whether these elevated cortisol levels shift risk preferences. Using a double-blind, placebo-controlled, cross-over protocol we raised cortisol levels in volunteers over 8 d to the same extent previously observed in traders. We then tested for the utility and probability weighting functions underlying their risk taking and found that participants became more risk-averse. We also observed that the weighting of probabilities became more distorted among men relative to women. These results suggest that risk preferences are highly dynamic. Specifically, the stress response calibrates risk taking to our circumstances, reducing it in times of prolonged uncertainty, such as a financial crisis. Physiology-induced shifts in risk preferences may thus be an underappreciated cause of market instability. PMID:24550472

We study consumer preferences for rye bread alternatives based on transgenic or cisgenic rye, grown conventionally...... pesticide-free production methods, and that while cisgenics is preferred over transgenics, the majority of respondents favour traditional breeding methods. The distribution in preferences suggests that some respondents prefer bread from cisgenic crops produced without pesticides over traditional crops...... produced using pesticides. Preferences for organic bread are stronger than for pesticide-free products. From a policy perspective results suggest that excluding cisgenics from mandatory labeling in the EU, or including it in the voluntary non-GM labelling in the US, would cause welfare losses for consumers....

  16. Wanting, liking, and preference construction.

    Dai, Xianchi; Brendl, C Miguel; Ariely, Dan

    2010-06-01

    According to theories on preference construction, multiple preferences result from multiple contexts (e.g., loss vs. gain frames). This implies that people can have different representations of a preference in different contexts. Drawing on Berridge's (1999) distinction between unconscious liking and wanting, we hypothesize that people may have multiple representations of a preference toward an object even within a single context. Specifically, we propose that people can have different representations of an object's motivational value, or incentive value, versus its emotional value, or likability, even when the object is placed in the same context. Study 1 establishes a divergence between incentive value and likability of faces using behavioral measures. Studies 2A and 2B, using self-report measures, provide support for our main hypothesis that people are perfectly aware of these distinct representations and are able to access them concurrently at will. We also discuss implications of our findings for the truism that people seek pleasure and for expectancy-value theories.

    Full Text Available Basic information files that revealing external users with information about the organization are the accounting financial statements. Reforms of the national accounting led to reduction of reporting forms informativeness and removal of transcripts. There was an obvious need for the formation of statements that reveals a wider range of indicators. Thus, integrated reporting can be such information array. Integrated reporting is the accounting tool, the information array about the organization. Integrated reporting includes such positions, as: a set of indicators characterized the economic, social and environmental aspects of the entity; the corporate management system that allows interested users to track the process of entity’s value creation and to form an opinion about its economic value. This type of reporting will be able to shape in accordance with the proposed methodological document "Rules of integrated reporting formation". This document assumes the following structure of integrated reporting: relevant information about the organization, historical information, environmental information, social information, innovation, internal control system, decoding of the financial statements, analysis of financial condition and financial results

    The objective of this study was to ascertain whether a symposium on elder abuse raises the level of knowledge and the self-reported likelihood to report elder abuse among licensed oral health care providers. 130 dentists, hygienists, and assistants voluntarily attended a 4-hour training symposium and completed both pre- and postsurveys testing their level of knowledge. Results by statistical analyses, using repeated measurements, Wilcoxon signed-rank test for nonparametric data, showed increases in awareness of reporting process, knowledge/awareness of elder abuse, knowledge of mandated reporter requirements, and comfort levels with recognizing signs and symptoms of elder abuse and neglect. In conclusion, a symposium can increase the self-reported likelihood of reporting elder abuse.

    Sleep habits and circadian preference (morningness/eveningness, M/E) have been extensively analyzed in adolescents and young adults, while few studies were conducted on children and early adolescents. Aim of the present study was to investigate the developmental changes of circadian preference and to analyze its relationship with sleep habits, sleep problems and circadian preference in a large sample by means of a school-based survey. One thousand seventy-three participants (50.8% boys and 49.2% girls; mean age = 10.6; range = 8-14 years), recruited from four schools randomly extracted within the district of Rome, completed a modified version of School Sleep Habits Survey developed by Carskadon et al. The questionnaire included items about sleep habits during schooldays and weekends; a Sleepiness Scale; a Sleep-Wake Problems Behaviour Scale; a Morningness/Eveningness scale. The results show a consistent age-related change in sleep habits, particularly in the weekends. The difference in sleep duration between schooldays and weekends increases linearly with age. No gender difference was observed in morningness/eveningness, while a significant linear increase in evening preference was found with increasing ages. M/E total scores correlated significantly with both self-reported sleep/wake problems and daytime sleepiness indicating a higher prevalence of sleep complaints in evening-type subjects. Overall, the present results support the existence of consistent age-related changes in sleep habits and M/E dimension in the 8- to 14-year age range.

    Individuals with anorexia nervosa (AN) restrict fat intake. The Geiselman Food Preference Questionnaire-I© (FPQ) is a validated self-report instrument that yields a fat preference score (>100 = high fat preference, preference). The goal of the study was to assess the utility of the FPQ in patients with AN. (1) to examine change in fat preference scores before and after weight restoration in hospitalized patients; and (2) to compare patients' scores before and after weight restoration to scores from healthy participants (HPs). The FPQ was completed by 88 patients and 115 HPs. Compared with HPs, patients had significantly lower fat preference scores before (74.03 ± 32.03 vs. 102.93 ± 16.89, P preference scores increased with weight gain (74.03 + 32.03 vs. 81.51 + 26.89, P preference for high fat foods. The FPQ may be a useful metric by which to assess improvements in diet during treatment. Further study is warranted to validate the FPQ against observed food intake in AN. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:148-151). © 2016 Wiley Periodicals, Inc.

  4. Brain serotonin signaling does not determine sexual preference in male mice.

    Directory of Open Access Journals (Sweden)

    Mariana Angoa-Pérez

    Full Text Available It was reported recently that male mice lacking brain serotonin (5-HT lose their preference for females (Liu et al., 2011, Nature, 472, 95-100, suggesting a role for 5-HT signaling in sexual preference. Regulation of sex preference by 5-HT lies outside of the well established roles in this behavior established for the vomeronasal organ (VNO and the main olfactory epithelium (MOE. Presently, mice with a null mutation in the gene for tryptophan hydroxylase 2 (TPH2, which are depleted of brain 5-HT, were tested for sexual preference. When presented with inanimate (urine scents from male or estrous female or animate (male or female mouse in estrus sexual stimuli, TPH2-/- males show a clear preference for female over male stimuli. When a TPH2-/- male is offered the simultaneous choice between an estrous female and a male mouse, no sexual preference is expressed. However, when confounding behaviors that are seen among 3 mice in the same cage are controlled, TPH2-/- mice, like their TPH2+/+ counterparts, express a clear preference for female mice. Female TPH2-/- mice are preferred by males over TPH2+/+ females but this does not lead to increased pregnancy success. In fact, if one or both partners in a mating pair are TPH2-/- in genotype, pregnancy success rates are significantly decreased. Finally, expression of the VNO-specific cation channel TRPC2 and of CNGA2 in the MOE of TPH2-/- mice is normal, consistent with behavioral findings that sexual preference of TPH2-/- males for females is intact. In conclusion, 5-HT signaling in brain does not determine sexual preference in male mice. The use of pharmacological agents that are non-selective for the 5-HT neuronal system and that have serious adverse effects may have contributed historically to the stance that 5-HT regulates sexual behavior, including sex partner preference.

  10. Preferred axis in cosmology

    CERN Document Server

    Zhao, Wen

    2016-01-01

    The foundation of modern cosmology relies on the so-called cosmological principle which states an homogeneous and isotropic distribution of matter in the universe on large scales. However, recent observations, such as the temperature anisotropy of the cosmic microwave background (CMB) radiation, the motion of galaxies in the universe, the polarization of quasars and the acceleration of the cosmic expansion, indicate preferred directions in the sky. If these directions have a cosmological origin, the cosmological principle would be violated, and modern cosmology should be reconsidered. In this paper, by considering the preferred axis in the CMB parity violation, we find that it coincides with the preferred axes in CMB quadrupole and CMB octopole, and they all align with the direction of the CMB kinematic dipole. In addition, the preferred directions in the velocity flows, quasar alignment, anisotropy of the cosmic acceleration, the handedness of spiral galaxies, and the angular distribution of the fine-structu...

  13. 'Too many girls, too much dowry': son preference and daughter aversion in rural Tamil Nadu, India.

    Diamond-Smith, Nadia; Luke, Nancy; McGarvey, Stephen

    2008-10-01

    The southern Indian state of Tamil Nadu has experienced a dramatic decline in fertility, accompanied by a trend of increased son preference. This paper reports on findings from qualitative interviews with women in rural villages about their fertility decision-making. Specifically addressed are the reasons behind increasing son preference and the consequences of this change. Findings suggest that daughter aversion, fuelled primarily by the perceived economic burden of daughters due to the proliferation of dowry, is playing a larger role in fertility decision-making than son preference. The desire for a son is often trumped by the worry over having many daughters. Women use various means of controlling the sex of their children, which in this study appear to be primarily female infanticide. It is important to distinguish between son preference and daughter aversion and to examine repercussions of low fertility within this setting.

  14. Preference for newspaper size.

    2014-05-01

    The past few years has seen a change in the size of newspapers, with publishers moving to a smaller size format. Five 'standard' newspaper sizes are used in different countries: Broadsheet, Rhensch, Tabloid, Tall Tabloid and Berliner. These papers vary in both width and height of pages and hence there are implications for human reading comfort, which may be dependent on reading location such as on a lounge chair or on a train. Experiments were carried out to determine preferences for the different sizes and to relate these preferences to the geometric characteristics of the newspapers. For both comfortable and cramped/uncomfortable reading conditions, the rank order of preference for paper types was, from least to most-preferred, Broadsheet, Rhensch, Berliner, Tall Tabloid and Tabloid. Preferences were much stronger when determined in cramped/uncomfortable reading conditions, where most comparisons were significantly different. There was good correlation between participant ratings on several scales and preference, where most factors were related to comfort of holding and controlling the paper.

  15. Self-Reports of Increased Prospective and Retrospective Memory Problems in Adults with Developmental Dyslexia.

    2016-08-01

    Short-term and working memory problems in dyslexia are well-documented, but other memory domains have received little empirical scrutiny, despite some evidence to suggest that they might be impaired. Prospective memory is memory for delayed intentions, whilst retrospective memory relates to memory for personally experienced past events. To gain an understanding of subjective everyday memory experience, a self-report measure designed to tap prospective and retrospective memory was administered to 28 adults with dyslexia and 26 IQ-matched adults without dyslexia. Adults with dyslexia reported experiencing significantly more frequent problems with memory than the adults without dyslexia. Group differences were found across seven out of the eight questionnaire scales. Further to these analyses, the participants' own ratings were compared with proxy ratings provided by close associates. The perception of poorer memory abilities in the participants did not differ between respondent types. The self-reported difficulties are, thus, unlikely to be the result of lowered self-esteem or metacognitive awareness. More frequent difficulties with both types of memory would seem, therefore, to be experienced by adults with dyslexia in everyday life. Further laboratory-based research is recommended to explore both memory domains in dyslexia and to identify the cognitive mechanisms by which these problems occur.

    The impact of stimulus size and presentation on choice during a preference assessment was investigated using a modified multiple-stimulus without replacement (MSWO) technique. Stimuli were either presented with a uniform magnitude, as determined by mass, or in a manner consistent with caregiver report of reinforcer consumption. While both assessment procedures identified the same top three preferred items in three out of five cases, greater variability in the preference rank of less preferred items was observed between assessments.

    Economic analysis has said little about how an individual's cognitive skills (CS's) are related to the individual's preferences in different choice domains, such as risk-taking or saving, and how preferences in different domains are related to each other. Using a sample of 1,000 trainee truckers we report three findings. First, we show a strong and significant relationship between an individual's cognitive skills and preferences, and between the preferences in different choice domains. The la...

  18. Increase of Expression Levels of Reporter Gene in Transgenic Tobaccos by Matrix Attachment Regions

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    The matrix attachment region (MAR) located downstream of Plastocyanin gene was isolated from the genome of pea. To study the effect of MARs on foreign gene expression in transgenic plants, T-DNA vector was constructed in which MARs flanked bothβ-glucuronidase(GUS) gene and selectable marker neomycin phosphotransferase (NPT-II) gene. The plant expression vectors were transferred into leaf discs via Agrobacterium-mediated transformation procedure. The result of GUS measurement showed that pea MAR could increase transgene expression level. The mean expression levels of GUS gene expression in population containing MARs could be increased twofold when compared with that of population without MARs.

    2000-01-01

    Most plan report cards that compare the performance of health plans have framed the decision about plan choice as an opportunity to get better-quality care. This study uses a controlled experimental design to examine the effect of reframing the health plan choice decision to one that emphasizes protecting oneself from possible risk. The findings show that framing the health plan decision using a risk message has a consistent and significant positive impact on how consumers comprehend, value, and weight comparative performance information.

    We report on a 35 year old patient suffering from heterochromia complicata Fuchs with a mature cataract. Multiple small whitish-yellowish crystal-lines on the iris at the 7 and 12 o'clock position were interpreted as Russell bodies and correlated with an elevated concentration of 7.2 mg/dl IgG in the aqueous humor analysis. IgA und IgM could not be detected (less than 1.1 mg/dl). Three months after an unremarkable extracapsular cataract extraction and posterior chamber lens implantation a positive Tyndall phenomenon and Russell bodies were found at just the same locations on the iris.

  4. Investors’ Risk Preference Characteristics and Conditional Skewness

    2014-01-01

    Full Text Available Perspective on behavioral finance, we take a new look at the characteristics of investors’ risk preference, building the D-GARCH-M model, DR-GARCH-M model, and GARCHC-M model to investigate their changes with states of gain and loss and values of return together with other time-varying characteristics of investors’ risk preference. Based on a full description of risk preference characteristic, we develop a GARCHCS-M model to study its effect on the return skewness. The top ten market value stock composite indexes from Global Stock Exchange in 2012 are adopted to make the empirical analysis. The results show that investors are risk aversion when they gain and risk seeking when they lose, which effectively explains the inconsistent risk-return relationship. Moreover, the degree of risk aversion rises with the increasing gain and that of risk seeking improves with the increasing losses. Meanwhile, we find that investors’ inherent risk preference in most countries displays risk seeking, and their current risk preference is influenced by last period’s risk preference and disturbances. At last, investors’ risk preferences affect the conditional skewness; specifically, their risk aversion makes return skewness reduce, while risk seeking makes the skewness increase.

  5. Preference assessments in the zoo: Keeper and staff predictions of enrichment preferences across species.

    Environmental enrichment is widely used in the management of zoo animals, and is an essential strategy for increasing the behavioral welfare of these populations. It may be difficult, however, to identify potentially effective enrichment strategies that are also cost-effective and readily available. An animal's preference for a potential enrichment item may be a reliable predictor of whether that individual will reliably interact with that item, and subsequently enable staff to evaluate the effects of that enrichment strategy. The aim of the present study was to assess the utility of preference assessments for identifying potential enrichment items across six different species--each representing a different taxonomic group. In addition, we evaluated the agreement between zoo personnel's predictions of animals' enrichment preferences and stimuli selected via a preference assessment. Five out of six species (nine out of 11 individuals) exhibited clear, systematic preferences for specific stimuli. Similarities in enrichment preferences were observed among all individuals of primates, whereas individuals within ungulate and avian species displayed individual differences in enrichment preferences. Overall, zoo personnel, regardless of experience level, were significantly more accurate at predicting least-preferred stimuli than most-preferred stimuli across species, and tended to make the same predictions for all individuals within a species. Preference assessments may therefore be a useful, efficient husbandry strategy for identifying viable enrichment items at both the individual and species levels. © 2015 Wiley Periodicals, Inc.

    Vitiligo is a skin disorder of unknown aetiology, affecting 0.1-2% of the general population. The aim of the present study was to investigate its relationship with sleep disorders, especially parasomnias. Two hundred and sixteen individuals were examined. Among them, 116 were suffering from vitiligo, 52 from other dermatological diseases and 48 were healthy subjects, serving as a control group. An inventory including items related to sleep disorders from childhood and adolescence was used. The study was focused specifically on parasomnias. Patients suffering from vitiligo reported a significantly higher occurrence of sleepwalking, nocturnal enuresis, night illusions, sleep terrors and nightmares than that of the control group, prior to the manifestation of the disease. Patients suffering from other dermatological diseases only reported significantly more often nightmares and nocturnal enuresis compared to the control group. A relationship between parasomnias during early life and later development of vitiligo was detected. This finding supports the hypothesis that neural mechanisms involving monoaminergic systems (especially the serotoninergic one) may potentially be involved in the aetiopathology of vitiligo.

  7. Sound preferences in urban open public spaces

    2003-10-01

    This paper studies people's perception of sound, based on an intensive questionnaire survey in fourteen urban open public spaces of five European countries. The questionnaire includes identification of recognized sounds, classification of sound preference, and indication of wanted and unwanted sounds. The results indicate three facets to people's sound preferences. First, people generally prefer natural and culture-related sounds rather than artificial sounds. Vehicle sounds and construction sounds are regarded as the most unpopular, whereas sounds from human activities are normally rated as neutral. Second, cultural background and long-term environmental experience play an important role in people's judgment of sound preference. People from a similar environment may show a similar tendency on their sound preferences, which can be defined as macro-preference. Third, personal differences, such as age and gender, further influence people's sound preference, which can be defined as micro-preference. For example, with increasing age, a higher percentage of people are favorable to, or tolerate, sounds relating to nature, culture or human activities. Male and female exhibit only slight differences.

    2010-09-01

    In the past several years, emphasis on quality metrics in the field of organ transplantation has increased significantly, largely because of the new conditions of participation issued by the Centers for Medicare and Medicaid Services. These regulations directly associate patients' outcomes and measured performance of centers with the distribution of public funding to institutions. Moreover, insurers and marketing ventures have used publicly available outcomes data from transplant centers for business decision making and advertisement purposes. We gave a 10-question survey to attendees of the Transplant Management Forum at the 2009 meeting of the United Network for Organ Sharing to ascertain how centers have responded to the increased oversight of performance. Of 63 responses, 55% indicated a low or near low performance rating at their center in the past 3 years. Respondents from low-performing centers were significantly more likely to indicate increased selection criteria for candidates (81% vs 38%, P = .001) and donors (77% vs 31%, P < .001) as well as alterations in clinical protocols (84% vs 52%, P = .007). Among respondents indicating lost insurance contracts (31%), these differences were also highly significant. Based on respondents' perceptions, outcomes of performance evaluations are associated with significant changes in clinical practice at transplant centers. The transplant community and policy makers should practice vigilance that performance evaluations and regulatory oversight do not inadvertently lead to diminished access to care among viable candidates or decreased transplant volume.

  9. Circadian Phase Preference in Pediatric Bipolar Disorder

    2014-03-01

    Full Text Available Pediatric bipolar disorder (BD rates have notably increased over the past three decades. Given the significant morbidity and mortality associated with BD, efforts are needed to identify factors useful in earlier detection to help address this serious public health concern. Sleep is particularly important to consider given the sequelae of disrupted sleep on normative functioning and that sleep is included in diagnostic criteria for both Major Depressive and Manic Episodes. Here, we examine one component of sleep—i.e., circadian phase preference with the behavioral construct of morningness/eveningness (M/E. In comparing 30 BD and 45 typically developing control (TDC participants, ages 7–17 years, on the Morningness-Eveningness Scale for Children (MESC, no between-group differences emerged. Similar results were found when comparing three groups (BD−ADHD; BD+ADHD; TDC. Consistent with data available on circadian phase preference in adults with BD, however, we found that BD adolescents, ages 13 years and older, endorsed significantly greater eveningness compared to their TDC peers. While the current findings are limited by reliance on subjective report and the high-rate of comorbid ADHD among the BD group, this finding that BD teens demonstrate an exaggerated shift towards eveningness than would be developmentally expected is important. Future studies should compare the circadian rhythms across the lifespan for individuals diagnosed with BD, as well as identify the point at which BD youth part ways with their healthy peers in terms of phase preference. In addition, given our BD sample was overall euthymic, it may be that M/E is more state vs. trait specific in latency age youth. Further work would benefit from assessing circadian functioning using a combination of rating forms and laboratory-based measures. Improved understanding of sleep in BD may identify behavioral targets for inclusion in prevention and intervention protocols.

  10. Preference for hope over knowledge

    Directory of Open Access Journals (Sweden)

    Cvetka Hedžet Tóth

    2012-12-01

    Full Text Available The article entitled Preference of Hope over Knowledge provides an analysis of the views of the American philosopher Richard Rorty, with special reference to concepts such as hope, utopia and the potential of ethics in the most recent times which, after the year of 1989, have been marked by the collapse of socialism of bolshevik origin. Thus knowledge is now preferred to hope, yet Rorty firmly insists that knowledge must keep its potential for hope, because it is the only way that humanism can maintain its existence. Even though we are faced with the end of the metaphysics of final certainty and its absolute principles, it is still possible to consider ethics and how it can be substantiated. Moral progress is possible, but not on the basis of something from the beyond, but rather as a matter of increasing sensitivity, increasing responsiveness to the needs of a larger and larger variety of people and things. It was with these views that Rorty established his ethics without principles, but in a very principled way as the anthropology of ethics that emphatically refuses to continue being the concealed voice of theos. The articles also highlights Rorty's comprehension of pragmatism conceived of as the philosophy of solidarity, since it expressly prefers solidarity to objectivity, solidarity being that other side of justice which remains one of the most basic concepts of every ethics.

    The flash visual evoked potential (VEP) is a useful diagnostic modality for visual preservation during surgery. Decreased VEP amplitude is recognized to indicate visual deterioration;however, whether intraoperative VEP can detect visual improvement remains unclear. We describe a craniopharyngioma case with a significant increase in VEP amplitude during surgery. A 67-year-old woman presented with progressive gait disturbance and impaired consciousness. Head magnetic resonance imaging demonstrated a sellar-suprasellar tumor compressing the optic chiasm upward with significant ventricular dilation. Her Glasgow Coma Scale was E3V3M5. Visual fields and acuity could not be examined because of impaired consciousness, and she could not see/recognize objects on a table. Preoperative VEP showed reproducible waveforms. Tumor removal by the extended transsphenoidal approach was performed with VEP monitoring. Increased VEP amplitude was observed after dural incision and persisted until the surgery ended. Postoperative VEP waveforms were also reproducible, but visual fields/acuity could not be examined because of cognitive dysfunction. Useful visual function was restored, and she became independent in daily life. The histological diagnosis was craniopharyngioma. The patient underwent ventriculo-peritoneal shunting for hydrocephalus 16 days after tumor removal. The postoperative course was uneventful and she was transferred to another hospital for rehabilitation. Intraoperative VEP may indicate visual improvement during surgery, which is a useful objective assessment for visual function in patients with impaired consciousness and cognitive dysfunction.

    The objective of the project is to increase biomass yields from coppice forests by admixing tree species (Alnus glutinosa, Robinia pseudoacacia and others) to plantations of Platanus occidentalis and Liquidambar styraciflua. Yield increases due to intensive cultivation, especially fertilization and irrigation, will be documented. A genetic improvement program of promising candidate species both through the identification of superior genotypes and mass cloning with tissue culture is also included. Three plantings have been established successfully to screen candidate species on various sites and to test the effects of weed control, fertilization and irrigation on short rotation forests. Two plantations in Georgia are in their 2nd and 3rd growing seasons while one in South Carolina is in its 1st growing season. A two acre plantation has been established to test development of geographic seed source material for sycamore. A nursery is in operation to develop seedling production methods for new species and to grow and maintain genetic material. Mass cloning of selected material by tissue culture techniques has produced material for testing in outplantings.

    Full Text Available CAM therapies have become increasingly popular in pediatric populations. Yet, little is known about children's preferences for CAM. This study examined treatment preferences in chronic pediatric pain patients offered a choice of CAM therapies for their pain. Participants were 129 children (94 girls (mean age = 14.5 years ± 2.4; range = 8–18 years presenting at a multidisciplinary, tertiary clinic specializing in pediatric chronic pain. Bivariate and multivariate analyses were used to examine the relationships between CAM treatment preferences and patient's sociodemographic and clinical characteristics, as well as their self-reported level of functioning. Over 60% of patients elected to try at least one CAM approach for pain. The most popular CAM therapies were biofeedback, yoga and hypnosis; the least popular were art therapy and energy healing, with craniosacral, acupuncture and massage being intermediate. Patients with a diagnosis of fibromyalgia (80% were the most likely to try CAM versus those with other pain diagnoses. In multivariate analyses, pain duration emerged as a significant predictor of CAM preferences. For mind-based approaches (i.e. hypnosis, biofeedback and art therapy, pain duration and limitations in family activities were both significant predictors. When given a choice of CAM therapies, this sample of children with chronic pain, irrespective of pain diagnosis, preferred non-invasive approaches that enhanced relaxation and increased somatic control. Longer duration of pain and greater impairment in functioning, particularly during family activities increased the likelihood that such patients agreed to engage in CAM treatments, especially those that were categorized as mind-based modalities.

    The aim of this study is to investigate if children’s food preferences can be reliable measured by using pictures of foods presented on a computer screen in a conjoint layout.We investigate reproducibility (test–retest) and infer validity by comparison with traditional hedonic evaluations...... juices (tangible products), chosen to span the preference spectrum, were hedonically evaluated for appearance and taste. Finally, an actual product choice was performed by having the children choose between two buns and two juices.Results showed that the computer evaluationswith pictures of foods...... provided reproducible information about the children’s visual food preferences, which were in concordance with both hedonic measures and products choices, and can thus be considered valid....

    A 37-year-old female smoker without a history of exposure to asbestos was referred to our hospital with persistent pericardial effusion. Chest computed tomography imaging examination revealed an irregular thickened pericardium with large amounts of pericardial effusion and a small pleural effusion. Fluorodeoxyglucose (FDG) positron emission tomography imaging demonstrated intrapericardial FDG accumulation. Blood tests revealed an increase in serum mesothelin levels. Examination of a surgically resected specimen revealed a grayish-white thickening of the pericardium, with a straw-colored mucinous pericardial effusion. Histopathological examination confirmed the diagnosis of epithelioid malignant mesothelioma. Although the patient's condition temporarily improved, with decreased levels of serum mesothelin during chemotherapy with carboplatin and pemetrexed, she succumbed to cardiac tamponade 18 months after the initial onset of the symptoms. Primary malignant pericardial mesothelioma (PMPM) is an extremely rare and refractory disorder. Thus, an early definitive diagnosis and timely treatment are crucial for the management of PMPM.

  20. Lexis? I prefer Mercedes. And sentences with verbs. : How lexis and deixis serve as vehicles for effective communication in English translations of French-language bank annual reports

    2016-01-01

    This thesis provides examples of cases where lexis and deixis in French to English translations of bank annual report shareholder letters do not align with the discourse found in English-original (“Anglo”) shareholder letters. It identifies potential traps of which translators should be aware, highlights what English translations of shareholder letters should read like based on examples taken from a large corpus of Anglo annual reports, and proposes more-effective translations that translator...

  1. [Marketing as a tool to increase the effectiveness of public health plans. 2008 SESPAS Report].

    Recent years have seen a steady increase in social marketing applied to health with the aim of increasing public awareness and changing people's behavior. Programs or actions based on the principles of social marketing have been shown to be effective in improving public health. However, that is not the general rule in Spain, where health policies have been based on health plans directed more to economic efficiency than to citizens' needs. For a health marketing program to be effective, the following factors are necessary: 1) the program has a long-term temporal horizon for action; 2) the objectives are established in terms of behavioral changes; 3) market research is used as a source of information; 4) different actions are established according to the segments identified as targets; 5) the program is operationalized in the four variables of the marketing mix, namely, product, price, distribution and communication, and is not only based on advertising campaigns; 6) the core of the program is exchange, understood as the factors that motivate people to change in return for the promise of something beneficial to them; 7) the factors or forces that compete with the desired behavioral changes are neutralized, and 8) businesses' social responsibility is used as a mechanism to reinforce health improvement programs. The design of health marketing programs should include definition of strategic and operational actions aimed not only at potential adopters of the desired behavior but also at all agents who may help or hinder behavioral change (health professionals, the pharmaceutical industry, politicians, the advertising industry, and products and services with health-challenging objectives).

    Different assumptions about travelers' scheduling preferences yield different measures of the cost of travel time variability. Only few forms of scheduling preferences provide non-trivial measures which are additive over links in transport networks where link travel times are arbitrarily...... of car drivers' route and mode choice under uncertain travel times. Our analysis exposes some important methodological issues related to complex non-linear scheduling models: One issue is identifying the point in time where the marginal utility of being at the destination becomes larger than the marginal...

    Autism diagnosis rates trail significantly in the African American community. This pre-test post-test pilot study evaluated an African American inner-city church health ambassadors (HAs) autism spectrum disorder (ASD) awareness training session. The participants included 12 HAs who attended the 1 hour training session organized by the National Baptist Convention, USA, Inc. Results of surveys showed higher mean scores post training for (1) HA attitudes about the potential for children to improve with applied behavior analysis therapy; (2) HA self-efficacy for having information about ASD screening materials; (3) strategies HAs could use to help parents/caregivers of children with developmental delays and challenging behaviors; (4) HA confidence in referrals for children with signs of ASD; (5) HA knowledge of measures to take to maximize a child's chance of receiving an ASD evaluation; and (6) HA comfort for talking to parents about children with challenging behaviors. Several of these effects were maintained 3 months later. Findings underscore the usefulness of the intervention for increasing the dissemination of knowledge about ASD and the opportunity to positively affect ASD screening, early intervention, and policy standards applicable to this vulnerable population.

    The purpose of this LDRD is to develop technology allowing warfighters to provide high-level commands to their unmanned assets, freeing them to command a group of them or commit the bulk of their attention elsewhere. To this end, a brain-emulating cognition and control architecture (BECCA) was developed, incorporating novel and uniquely capable feature creation and reinforcement learning algorithms. BECCA was demonstrated on both a mobile manipulator platform and on a seven degree of freedom serial link robot arm. Existing military ground robots are almost universally teleoperated and occupy the complete attention of an operator. They may remove a soldier from harm's way, but they do not necessarily reduce manpower requirements. Current research efforts to solve the problem of autonomous operation in an unstructured, dynamic environment fall short of the desired performance. In order to increase the effectiveness of unmanned vehicle (UV) operators, we proposed to develop robots that can be 'directed' rather than remote-controlled. They are instructed and trained by human operators, rather than driven. The technical approach is modeled closely on psychological and neuroscientific models of human learning. Two Sandia-developed models are utilized in this effort: the Sandia Cognitive Framework (SCF), a cognitive psychology-based model of human processes, and BECCA, a psychophysical-based model of learning, motor control, and conceptualization. Together, these models span the functional space from perceptuo-motor abilities, to high-level motivational and attentional processes.

    Detecting the evolution properties of online user preference diversity is of significance for deeply understanding online collective behaviors. In this paper, we empirically explore the evolution patterns of online user rating preference, where the preference diversity is measured by the variation coefficient of the user rating sequence. The statistical results for four real systems show that, for movies and reviews, the user rating preference would become diverse and then get centralized finally. By introducing the empirical variation coefficient, we present a Markov model, which could regenerate the evolution properties of two online systems regarding to the stable variation coefficients. In addition, we investigate the evolution of the correlation between the user ratings and the object qualities, and find that the correlation would keep increasing as the user degree increases. This work could be helpful for understanding the anchoring bias and memory effects of the online user collective behaviors.

    During the first months of life, infants switch from a preference for perfect contingent feedback to a preference for less-than-perfect contingent feedback of their own movements. This is an indicator of increasing social interest since others provide less-than-perfect contingent feedback whereas the self provides perfect contingent feedback. We presented 117 6-month-olds with real-time and delayed video feedback of self-performed leg movements and asked parents about difficulties in various socioemotional domains. It was hypothesized that the more infants prefer real-time and therefore perfect contingent feedback over 7 s delayed and therefore perceived noncontingent feedback, the more difficulties parents will report in interaction and communication with their child. Preference for real-time feedback was related to difficulties in interaction, but not to difficulties in communication. Implications of this finding for infants' socioemotional development and health are discussed.

  8. Use of a Fish Transportation Barge for Increasing Returns of Steelhead Imprinted for Homing, Final Report.

    The objective of this 7-year National Fisheries Service study, which began is 1982, was to determine if transporting juvenile steelhead (Oncorhynchus mykiss) by truck and barge from Dworshak National Fish Hatchery (NFH), on the Clearwater River, to a release site on the Columbia River below Bonneville Dam would result in increased returns of adults to the various fisheries and to the hatchery homing site. During 1982 and 1983, over 500,000 marked juvenile steelhead were serially released as controls from the hatchery or barged as test fish to below Bonneville Dam. Recoveries of marked adults to various recovery sites are complete. Fish released in 1983 showed a stronger homing ability and more rapid upstream migration than test fish released in 1982. Most adults from both control and test releases in 1983 and control releases in 1982 migrated a considerable distance upstream and overwintered in the Snake and Clearwater Rivers--behavior similar to Clearwater River fish previously transported from Lower Granite Dam. In contrast, many of the adults from test releases in 1982 failed to migrate upstream during the fall, overwintered in the Columbia River, and migrated upstream the following spring. Survival of control fish released at Dworshak NFH in late April 1982 was substantially higher than survival of those released in mid-May. Survival and homing of control fish released in late April and early May 1983 were over 10 times that for fish released in late May. Return of adults from normal hatchery releases in 1982 was the highest ever observed at Dworshak NFH.

    A connection between preferences for heavy metal, rap, reggae, electronic dance music, and substance use has previously been established. However, evidence as to the gender-specific links between substance use and a wider range of music genres in a nationally representative sample of adolescents has to date been missing. In 2003, the Dutch government funded the Dutch National School Survey on Substance Use (DNSSSU), a self-report questionnaire among a representative school-based sample of 7,324 adolescents aged 12 to 16 years, assessed music preference, tobacco, and alcohol use and a set of relevant covariates related to both substance use and music preference. Overall, when all other factors were controlled, punk/hardcore, techno/hardhouse, and reggae were associated with more substance use, while pop and classical music marked less substance use. While prior research showed that liking heavy metal and rap predicts substance use, in this study a preference for rap/hip-hop only indicated elevated smoking among girls, whereas heavy metal was associated with less smoking among boys and less drinking among girls. The types of music that mark increased substance use may vary historically and cross-culturally, but, in general, preferences for nonmainstream music are associated positively with substance use, and preferences for mainstream pop and types of music preferred by adults (classical music) mark less substance use among adolescents. As this is a correlational study no valid conclusions in the direction of causation of the music-substance use link can be drawn.

    A systematic fuzzy approach is developed to model fuzziness and uncertainties in the preferences of decision makers involved in a conflict. This unique fuzzy preference formulation is used within the paradigm of the Graph Model for Conflict Resolution in which a given dispute is modeled in terms of decision makers, each decision maker's courses of actions or options, and each decision maker's preferences concerning the states or outcomes which could take place. In order to be able to determine the stability of each state for each decision maker and the possible equilibria or resolutions, a range of solution concepts describing potential human behavior under conflict are defined for use with fuzzy preferences. More specifically, strong and weak definitions of stability are provided for the solution concepts called Nash, general metarational, symmetric metarational, and sequential stability. To illustrate how these solution concepts can be conveniently used in practice, they are applied to a dispute over the contamination of an aquifer by a chemical company located in Elmira, Ontario, Canada.

  15. The influence of the digital divide on face preferences in El Salvador: people without internet access prefer more feminine men, more masculine women, and women with higher adiposity.

    2014-01-01

    Previous studies on face preferences have found that online and laboratory experiments yield similar results with samples from developed countries, where the majority of the population has internet access. No study has yet explored whether the same holds true in developing countries, where the majority of the population does not have internet access. This gap in the literature has become increasingly important given that several online studies are now using cross-country comparisons. We therefore sought to determine if an online sample is representative of the population in the developing country of El Salvador. In studies of Hispanic men and women aged 18-25, we tested facial masculinity and adiposity preferences by collecting data in person as well as online. Our results showed that there were no differences in preferences between people who reported having internet access, whether they were tested online or in person. This provides evidence that testing style does not bias preferences among the same population. On the other hand, our results showed multiple differences in preferences between people who reported having internet access and people who reported not having internet access. More specifically, we found that people without internet access preferred more feminine men, more masculine women, and women with higher adiposity than people with internet access. We also found that people without internet access had fewer resources (e.g. running water) than people with internet access, suggesting that harshness in the environment may be influencing face preferences. These findings suggest that online studies may provide a distorted perspective of the populations in developing countries.

    : This study confirms that there are significant differences in the reward preferences of different segments. Management can more effectively structure reward models according to these preferences without increasing overall costs. Contribution/value-add: The existing body of knowledge on the reward preferences of people with different personality types and personality preferences are enhanced. In addition, the study on the reward preferences of different demographic groups within a South African context adds considerably to the existing body of literature. Based on research results, a total rewards framework, on employee preferences, was designed. Furthermore, an increased understanding of the reward categories that contribute towards .the attraction, retention and motivation of employees as well as preferences for certain reward categories, have been obtained.

    1998-06-01

    Evidence for an association between early pregnancy sickness and offspring salt (NaCl) preference has been obtained from studying offspring as young adults. To determine whether effects on NaCl preference are expressed in infancy, the present study examined 16-week-old infants whose mothers reported either little or no vomiting (N = 15) or frequent moderate to severe vomiting (N = 14) during the first 14 weeks of their pregnancy. The infants' oral-motor facial reactions to each solution and their relative intakes of distilled water and 0.1m and 0.2m NaCl were used as measures of preference. Infants of mothers who reported no or mild symptoms had a significantly lower relative intake of salt solutions than infants whose mothers reported moderate to severe symptoms (p < 0.01). The former infants also showed a greater number of aversive facial responses when given 0.2m NaCl (p < 0.05). Taken together, these findings support the hypothesis that maternal dehydration, induced by moderate to severe vomiting during pregnancy, can lead to enhanced salt preference in offspring. They also provide a potential explanation for some of the variability encountered when human infants are tested for their salt preference.

    No more than 30 cases of phaeohyphomycosis caused by Exophiala spinifera have been reported up to now in English and Chinese literature over the past half century. Here, we reported two cases of phaeohyphomycosis caused by E. spinifera and reviewed all the five cases reported from mainland China. These two involved were both young female, one patient experiencing recurrence during pregnancy and the other developing multiple-site infections without apparent immunodeficiency. The aetiological agents were both identified as E. spinifera by molecular analysis. Oral itraconazole was proved effective enough for the first patient, while the combination of itraconazole and terbinafine was needed for the second patient. It seems that infections due to E. spiniferais increasing in China mainland nowadays, usually involving young female.

    We report two experiments on the perceived aesthetic quality of random density texture patterns. In each experiment a square grid was filled with a progressively larger number of elements. Grid size in Experiment 1 was 10×10 with elements added to create a variety of textures ranging from 10%-100% fill levels. Participants rated the beauty of the patterns. Average judgments across all observers showed an inverted U-shaped function that peaked near middle densities. In Experiment 2 grid size was increased to 15×15 to see if observers preferred patterns with a fixed density or a fixed number of elements. The results of the second experiment were nearly identical to that of the first showing a preference for density over fixed element number. Ratings in both studies correlated positively with a GIF compression metric of complexity and with edge length. Within the range of stimuli used, observers judge more complex patterns to be more beautiful.

    Full Text Available Table olive production sector is undergoing rapid changes, as the government is undertaking an ambitious program supporting the expansion of olive grove plantations. Despite the increase in domestic production, import of table olive is still high, due to constraints in quantity and quality of domestically supplied olives. In the context of import substitution strategy, embraced by producers and policy-makers, it is important to analyze the consumer preferences for table olives. The objective of this paper is to segment the table olive market according to preferences for table olives attributes applying Conjoint Choice Experiment (CCE and Latent Class Analysis to collect and analyze the data. The research results show a strong consumer preference for domestic table olives whereas preferences for other attributes vary between consumer groups.

    Female smokers have greater difficulty quitting, possibly due to increased reactivity to smoking-related cues. This study assessed sex differences in craving, affect, and preference for immediate smoking after cue exposure. Regular smokers (n = 60; 50% female) were exposed to smoking and neutral cues in separate, counterbalanced sessions. Outcomes included changes in craving and affect and preference for immediate smoking following cue exposure. Findings indicated that women exhibited greater preference for immediate smoking (p = .004), and reported greater cue-induced increases in cigarette craving (p = .046) and negative affect (p = .025). These data suggest that women may have greater difficulty inhibiting smoking after cue exposure, possibly as a consequence of greater increases in craving and negative affect. Findings suggest a mechanism that may contribute to greater cessation failure among female smokers. © American Academy of Addiction Psychiatry.

  5. Nutritional state influences shoaling preference for familiars.

    2007-01-01

    Preferences for grouping with familiar individuals are shown in many animal species, including the three-spined stickleback (Gasterosteus aculeatus). Shoaling with familiars is advantageous because of more precise anti-predator behaviours or more stable dominance hierarchies. Additionally, associations with familiar individuals facilitate the evolution of altruistic behaviour. Thus, in situations of increased competition one might expect an increased preference for familiar fish. We gave single juvenile sticklebacks of different nutritional state the choice between shoals composed either of familiar or unfamiliar individuals. Satiated fish preferred to shoal with familiar individuals. A comparative analysis of 8 stickleback studies with 15 different tests using familiars showed that all tests gave similar results, i.e. sticklebacks of all age classes preferred to shoal with familiars in a non-sexual context. In contrast, hungry test fish did not prefer to shoal with familiar fish, but even showed a preference for the unfamiliar group. Because sticklebacks use early-life familiarity to recognize kin, the results suggest the avoidance of competition with relatives. To our knowledge, this is the first study showing an impact of nutritional state on social interactions with familiar individuals.

  6. Infants' preference for native audiovisual speech dissociated from congruency preference.

    Directory of Open Access Journals (Sweden)

    Kathleen Shaw

    Full Text Available Although infant speech perception in often studied in isolated modalities, infants' experience with speech is largely multimodal (i.e., speech sounds they hear are accompanied by articulating faces. Across two experiments, we tested infants' sensitivity to the relationship between the auditory and visual components of audiovisual speech in their native (English and non-native (Spanish language. In Experiment 1, infants' looking times were measured during a preferential looking task in which they saw two simultaneous visual speech streams articulating a story, one in English and the other in Spanish, while they heard either the English or the Spanish version of the story. In Experiment 2, looking times from another group of infants were measured as they watched single displays of congruent and incongruent combinations of English and Spanish audio and visual speech streams. Findings demonstrated an age-related increase in looking towards the native relative to non-native visual speech stream when accompanied by the corresponding (native auditory speech. This increase in native language preference did not appear to be driven by a difference in preference for native vs. non-native audiovisual congruence as we observed no difference in looking times at the audiovisual streams in Experiment 2.

  7. Goodbye genome paper, hello genome report: the increasing popularity of 'genome announcements' and their impact on science.

    Smith, David Roy

    2016-06-23

    Next-generation sequencing technologies have revolutionized genomics and altered the scientific publication landscape. Life-science journals abound with genome papers-peer-reviewed descriptions of newly sequenced chromosomes. Although they once filled the pages of Nature and Science, genome papers are now mostly relegated to journals with low-impact factors. Some have forecast the death of the genome paper and argued that they are using up valuable resources and not advancing science. However, the publication rate of genome papers is on the rise. This increase is largely because some journals have created a new category of manuscript called genome reports, which are short, fast-tracked papers describing a chromosome sequence(s), its GenBank accession number and little else. In 2015, for example, more than 2000 genome reports were published, and 2016 is poised to bring even more. Here, I highlight the growing popularity of genome reports and discuss their merits, drawbacks and impact on science and the academic publication infrastructure. Genome reports can be excellent assets for the research community, but they are also being used as quick and easy routes to a publication, and in some instances they are not peer reviewed. One of the best arguments for genome reports is that they are a citable, user-generated genomic resource providing essential methodological and biological information, which may not be present in the sequence database. But they are expensive and time-consuming avenues for achieving such a goal.

    To determine if the rate of major discrepancies between resident preliminary reports and faculty final reports increases during the final hours of consecutive 12-hour overnight call shifts. Institutional review board exemption status was obtained for this study. All overnight radiology reports interpreted by residents on-call between January 2010 and June 2010 were reviewed by board-certified faculty and categorized as major discrepancies if they contained a change in interpretation with the potential to impact patient management or outcome. Initial determination of a major discrepancy was at the discretion of individual faculty radiologists based on this general definition. Studies categorized as major discrepancies were secondarily reviewed by the residency program director (M.H.S.) to ensure consistent application of the major discrepancy designation. Multiple variables associated with each report were collected and analyzed, including the time of preliminary interpretation, time into shift study was interpreted, volume of studies interpreted during each shift, day of the week, patient location (inpatient or emergency department), block of shift (2-hour blocks for 12-hour shifts), imaging modality, patient age and gender, resident identification, and faculty identification. Univariate risk factor analysis was performed to determine the optimal data format of each variable (ie, continuous versus categorical). A multivariate logistic regression model was then constructed to account for confounding between variables and identify independent risk factors for major discrepancies. We analyzed 8062 preliminary resident reports with 79 major discrepancies (1.0%). There was a statistically significant increase in major discrepancy rate during the final 2 hours of consecutive 12-hour call shifts. Multivariate analysis confirmed that interpretation during the last 2 hours of 12-hour call shifts (odds ratio (OR) 1.94, 95% confidence interval (CI) 1.18-3.21), cross

  11. Coaching preferences of athletes.

    The study examined the coaching preferences of 80 male and 80 female athletes, as measured by the Leadership Scale for Sports (Chelladurai and Saleh, 1978, 1980). In addition, it attempted to assess the applicability to sport of the Life-cycle and Path-goal theories of leadership. Comparisons between groups were made on the basis of sex, age, and type of sport. A MANOVA indicated that athletes in independent sports preferred more democratic behaviour (p less than .001) and less autocratic behaviour (p = .028) than athletes in interdependent sports. No differences in coaching preferences were found which could be attributed to the age or sex of the athlete, or the variability of the sports task. These results partially supported the Path-goal theory, but did not support the Life-cycle theory. Athletes of all groups tended to favour coaches who displayed training behaviour and rewarding behaviour "often", democratic behaviour and social support behaviour "occasionally", and autocratic behaviour "seldom". This consistency may be a useful finding for those organizations and institutions interested in preparing coaches.

  12. Perspectives on Preference Aggregation.

    For centuries, the mathematical aggregation of preferences by groups, organizations, or society itself has received keen interdisciplinary attention. Extensive theoretical work in economics and political science throughout the second half of the 20th century has highlighted the idea that competing notions of rational social choice intrinsically contradict each other. This has led some researchers to consider coherent democratic decision making to be a mathematical impossibility. Recent empirical work in psychology qualifies that view. This nontechnical review sketches a quantitative research paradigm for the behavioral investigation of mathematical social choice rules on real ballots, experimental choices, or attitudinal survey data. The article poses a series of open questions. Some classical work sometimes makes assumptions about voter preferences that are descriptively invalid. Do such technical assumptions lead the theory astray? How can empirical work inform the formulation of meaningful theoretical primitives? Classical "impossibility results" leverage the fact that certain desirable mathematical properties logically cannot hold in all conceivable electorates. Do these properties nonetheless hold true in empirical distributions of preferences? Will future behavioral analyses continue to contradict the expectations of established theory? Under what conditions do competing consensus methods yield identical outcomes and why do they do so?

    The main purpose of this study was to evaluate the associations between salty food preference and osteoporosis (OP) in general Chinese men. We conducted a largescale, community-based, cross-sectional study to estimate the associations by using self-report questionnaire to evaluate the salty food preference. The total of 1,092 men was available to data analysis in this study. Multiple regression models controlling for confounding factors to include salty food preference variables were employed to explore the relationships for OP. We found negative correlations between preference for salty food and T-score (p=0.006). Multiple regression analysis showed that the preference for salty food was significantly positively associated with OP (ppreference for salty food habits had a higher prevalence of OP. The findings indicated that salty food preference was independently and significantly associated with OP. The prevalence of OP was more frequent in Chinese men preferring salty food habits.

    In New Brunswick, efforts to control populations of spruce budmoth by spraying adults with insecticides or pheromones have produced encouraging results. An alternative technique, the selection of less-susceptible spruce, would aid in the development of an integrated management program for this insect pest. Differences in spruce damage as revealed in previous studies could be due to oviposition choice and/or to host suitability. However, researchers must determine the distribution of eggs laid by the spruce budmoth before they can determine whether some families of spruce have low levels of damage because they are avoided by ovipositing females and/or because they are less suitable for egg and larval development. This report presents results from studies carried out to quantify the number of eggs laid on trees from different families. Investigators collected tree branch samples from plantations and a seed orchard in May, before bud burst or egg hatching commenced. They analysed variations in oviposition parameters (such as number of eggs and egg masses, number of eggs parasitized by Trichogramma minutum, and number of viable eggs) using analysis of variance. To determine whether differences in egg density were related to plant morphology, they also measured such parameters as shoot length and diameter, needle length, shot type, and needle density.

    The potential of methamphetamine, and high-potency crystal methamphetamine in particular, to precipitate psychotic symptoms and psychotic illness is the subject of much speculation internationally. Established psychotic illness is disabling for individuals and costly to society. The aim of this study was to investigate whether use of crystal methamphetamine was associated with greater prevalence of self-reported psychotic illness, compared to use of other forms of methamphetamine. The sample comprised participants interviewed as part of an annual cross-sectional survey of Australian people who inject drugs. Comparisons were made between groups according to the nature of their methamphetamine use: crystal methamphetamine or other forms of methamphetamine. Self-reported diagnoses of psychotic illness and other mental health problems were compared between groups. Predictors of self-reported psychotic illness were examined using multivariable logistic regression analyses. Self-reported psychotic illness was highly prevalent among users of crystal methamphetamine (12.0%), and significantly more so than among users of other forms of methamphetamine (3.9%) (OR=3.36; CI: 1.03-10.97). Significant predictors of self-reported psychosis in the cohort were: use of crystal methamphetamine; dependent use; lack of education beyond high school; and younger age. Highly increased prevalence of self-reported psychotic illness is associated with use of high-potency crystal methamphetamine in people who inject drugs, particularly where there is dependent use. There is an urgent need to develop effective interventions for dependent crystal methamphetamine use; and a need to monitor for symptoms of psychotic illness in drug-using populations.

    A poor appetite in older adults is an important determinant of reduced food intake and undernutrition. Food preferences may influence food intake. The aim of this study was to investigate food preferences of older adults with a poor appetite and compare these with preferences of older adults with a good appetite. Older adults (n = 349, aged 65-101 years) in nursing/residential care homes, hospitals or at home receiving home care participated in a computer-based forced-choice food preference assessment. Self-reported appetite in the past week was classified as 'good' or 'poor' using a validated instrument. Food preferences were determined by counting the relative frequency of choices for food images according to 11 dichotomous categories: high/low 1) protein; 2) fat; 3) carbohydrates; 4) fiber; 5) variation; and 6) animal/vegetarian proteins; 7) sweet/savory taste; 8) solid/liquid texture; 9) dairy/non-dairy; with/without 10) sauce or 11) color variation. Specific food preferences in participants with a poor appetite were identified by one-sample t-tests comparing frequencies to the expected value of 48. Preference differences between those with a good and a poor appetite were analyzed using GLM adjusting for confounders. The results showed that older adults with a poor appetite (n = 113; 32.4%) preferred variation (51.6 vs. 48, P food preferences. Their preference for variation differs from those with a good appetite. These results may be used to develop meals that are preferred by older adults with poor appetite in order to increase food intake and prevent undernutrition. Copyright © 2015 Elsevier Ltd.

    One of the major contributing factors to the continuous rise in obesity rates is the increase in caloric intake, which is driven to a large extent by the ease of access and availability of palatable high-fat, high-sugar 'junk foods'. It is also clear that some individuals are more likely to overindulge in these foods than others; however, the factors that determine an individual's susceptibility towards the overconsumption of palatable foods are not well understood. There is growing evidence that an increased preference for these foods may have its origins early in life. Recent work from our group and others has reported that in utero and early life exposure to these palatable foods in rodents increased the offspring's preference towards foods high in fat and sugar. One of the potential mechanisms underlying the programming of food preferences is the altered development of the mesolimbic reward system, a system that plays an important role in driving palatable food intake in adults. The aim of this review is to explore the current knowledge of the programming of food preferences, a relatively new and emerging area in the DOHAD field, with a particular focus on maternal overnutrition, the development of the mesolimbic reward system and the biological mechanisms which may account for the early origins of an increased preference for palatable foods.

    This project was conducted to identify student preferences for e-teaching and learning. An online Student Preferences for Learning with E-Technology Survey was developed to assess computer experiences, the use and effectiveness of e-resources, preferences for various environments, need for standardization, and preferred modes of communication. The survey was administered in May 2008 to all dental and dental hygiene students at Baylor College of Dentistry. There was an 85 percent response rate (n=366/432). About two-thirds of the students found college e-resources effective for learning. They preferred printed text over digital (64 percent) and wanted e-materials to supplement but not replace lectures (74 percent). They reported e-materials would "extensively" enhance learning, such as e-lectures (59 percent), clinical videos (54 percent), and podcasts (45 percent). They reported the need for a central location for e-resources (98 percent) and an e-syllabus for every course (86 percent) in a standard format (77 percent). One difficulty reported was accessing e-materials from external locations (33 percent). Students commented on the need for faculty training and standardization of grade posting. A qualitative theme was that e-resources should not replace interactions with faculty. Some infrastructure problems have been corrected. Planning has begun for standardization and expansion of e-resources. These improvements should enhance learning and increase the options for individualizing instruction, study strategies, and course remediation.

    Full Text Available Abstract Background Shared decision-making has been advocated; however there are relatively few studies on physician preferences for, and experiences of, different styles of clinical decision-making as most research has focused on patient preferences and experiences. The objectives of this study were to determine 1 physician preferences for different styles of clinical decision-making; 2 styles of clinical decision-making physicians perceive themselves as practicing; and 3 the congruence between preferred and perceived style. In addition we sought to determine physician perceptions of the availability of time in visits, and their role in encouraging patients to look for health information. Methods Cross-sectional survey of a nationally representative sample of U.S. physicians. Results 1,050 (53% response rate physicians responded to the survey. Of these, 780 (75% preferred to share decision-making with their patients, 142 (14% preferred paternalism, and 118 (11% preferred consumerism. 87% of physicians perceived themselves as practicing their preferred style. Physicians who preferred their patients to play an active role in decision-making were more likely to report encouraging patients to look for information, and to report having enough time in visits. Conclusion Physicians tend to perceive themselves as practicing their preferred role in clinical decision-making. The direction of the association cannot be inferred from these data; however, we suggest that interventions aimed at promoting shared decision-making need to target physicians as well as patients.

  3. ‘Too many girls, too much dowry’: son preference and daughter aversion in rural Tamil Nadu, India

    The southern Indian state of Tamil Nadu has experienced a dramatic decline in fertility, accompanied by a trend of increased son preference. This paper reports on findings from qualitative interviews with women in rural villages about their fertility decision-making. Specifically addressed are the reasons behind increasing son preference and the consequences of this change. Findings suggest that daughter aversion, fuelled primarily by the perceived economic burden of daughters due to the proliferation of dowry, is playing a larger role in fertility decision-making than son preference. The desire for a son is often trumped by the worry over having many daughters. Women use various means of controlling the sex of their children, which in this study appear to be primarily female infanticide. It is important to distinguish between son preference and daughter aversion and to examine repercussions of low fertility within this setting. PMID:18821352

    The University of Houston is in the process of developing a flexible program that offers children an in-depth educational experience culminating in the design and construction of their own model Mars rover. The program is called the Mars Rover Model Celebration (MRC). It focuses on students, teachers and parents in grades 3-8. Students design and build a model of a Mars rover to carry out a student selected science mission on the surface of Mars. A total of 65 Mars Rover teachers from the 2012-2013 cohort were invited to complete the Mars Rover Teacher Evaluation Survey. The survey was administered online and could be taken at the convenience of the participant. In total, 29 teachers participated in the survey. Teachers were asked to rate their current level of confidence in their ability to teach specific topics within the Earth and Life Science realms, as well as their confidence in their ability to implement teaching strategies with their students. In addition, they were asked to rate the degree to which they felt their confidence increased in the past year as a result of their participation in the MRC program. The majority of teachers (81-90%) felt somewhat to very confident in their ability to effectively teach concepts related to earth and life sciences to their students. In addition, many of the teachers felt that their confidence in teaching these concepts increased somewhat to quite a bit as a result of their participation in the MRC program (54-88%). The most striking increase in this area was the reported 48% of teachers who felt their confidence in teaching 'Earth and the solar system and universe' increased 'Quite a bit' as a result of their participation in the MRC program. The vast majority of teachers (86-100%) felt somewhat to very confident in their ability to effectively implement all of the listed teaching strategies. In addition, the vast majority reported believing that their confidence increased somewhat to quite a bit as a result of their

  8. A New Method of Random Environmental Walking for Assessing Behavioral Preferences for Different Lighting Applications.

    2017-01-01

    Accurate assessment of people's preferences for different outdoor lighting applications is increasingly considered important in the development of new urban environments. Here a new method of random environmental walking is proposed to complement current methods of assessing urban lighting applications, such as self-report questionnaires. The procedure involves participants repeatedly walking between different lighting applications by random selection of a lighting application and preferred choice or by random selection of a lighting application alone. In this manner, participants are exposed to all lighting applications of interest more than once and participants' preferences for the different lighting applications are reflected in the number of times they walk to each lighting application. On the basis of an initial simulation study, to explore the feasibility of this approach, a comprehensive field test was undertaken. The field test included random environmental walking and collection of participants' subjective ratings of perceived pleasantness (PP), perceived quality, perceived strength, and perceived flicker of four lighting applications. The results indicate that random environmental walking can reveal participants' preferences for different lighting applications that, in the present study, conformed to participants' ratings of PP and perceived quality of the lighting applications. As a complement to subjectively stated environmental preferences, random environmental walking has the potential to expose behavioral preferences for different lighting applications.

    Full Text Available Fish consumption preferences are affected by individuals’ socioeconomic characteristics. The aims of the present paper were (i to obtain information on fish consumption level and frequency; (ii to investigate the associations between the socioeconomic characteristics of consumers and their preferences; and (iii to examine the influence of determinants on fish consumption. Data were gathered through a questionnaire completed by a total of 127 randomly selected individuals from different socioeconomic backgrounds from the Antakya, Turkey. The average consumption was found to be 2.98 kg/person/year for fish. Anchovies, gilt-head sea bream, and sea bass were reported as the most consumed three species, respectively. Significant differences in fish consumption were found among age groups, gender groups, and education groups, as well as between marital statuses. A majority of the consumers eat fish once a month throughout the year or only during the winter months. Fish consumption level and frequency were significantly positively correlated with education (p<0.01, income (p<0.05 and total meat consumption (p<0.01. The stepwise multiple regression model explained 41.7% (p<0.01 of the total variance for fish consumption. The amount and frequency of the consumption in the region, which is very far below the world and Turkey average especially for lower socioeconomic groups and for less-consumed fish species, can be increased by certain policies, such as training, advertising and different marketing strategies. Moreover, consumption should be distributed equally throughout the year instead of consuming only in certain seasons.

    This paper reports experimental evidence on a stylized labor market. The experiment is designed as a sequence of three phases. In the first two phases, P1 and P2; agents face simple games, which we use to estimate subjects' social and reciprocity concerns, together with their beliefs. In the last...... phase, P3; four principals, who face four teams of two agents, compete by offering agents a contract from a fixed menu. Then, each agent selects one of the available contracts (i.e. he "chooses to work" for a principal). Production is determined by the outcome of a simple effort game induced...... by the chosen contract. We find that (heterogeneous) social preferences are significant determinants of choices in all phases of the experiment. Since the available contracts display a trade-off between fairness and strategic uncertainty, we observe that the latter is a much stronger determinant of choices...

  11. Why do women not prefer much older men? a hypothesis based on alterations in male reproductive physiology related to increased age Por que mulheres não preferem homens muito mais velhos que elas? uma hipótese baseada em alterações da fisiologia reprodutiva masculina relacionadas ao aumento da idade

    Full Text Available Evolutionary Psychology studies suggest that women prefer slightly older or similarly aged partners, although to date few hypotheses have been put forth to explain this pattern of choice. Several recent studies have shown changes in male reproductive parameters as a result of increased age. In the current review of medical literature, we found evidence that much older men are more likely to be infertile, women with much older partners are more likely to experience problems during pregnancy, and children of much older men are more likely to have genetic abnormalities. Based on these findings, we suggest that reproducing with much older men does not represent the best reproductive option for women, which would explain the female preference for only slightly older or similarly-aged mates.Estudos de Psicologia Evolucionista sugerem que as mulheres preferem parceiros um pouco mais velhos ou de idade semelhante, embora apresentem, até agora, poucas hipóteses para explicar esse padrão de preferência. Recentemente, vários estudos têm demonstrado alterações nos parâmetros reprodutivos masculinos como resultado do aumento da idade. Em revisão da literatura médica atual, encontramos evidências de que homens muito mais velhos são mais susceptíveis de serem inférteis, mulheres com parceiros muito mais velhos são mais propensas a sofrer com problemas durante a gravidez e filhos de homens muito mais velhos são mais propensos a ter anomalias genéticas. Com base nestes resultados, sugerimos que reproduzir com homens muito mais velhos não representa a melhor opção reprodutiva para as mulheres, o que explicaria a preferência feminina por parceiros apenas um pouco mais velhos ou de mesma faixa etária.

    2017-01-01

    Information about treatment side effects can increase their occurrence; breast cancer (BC) patients showed increased cognitive problem reporting (CPR) and decreased memory performance after information about cognitive side effects. The current study extends previous research on adverse information effects (AIE) by investigating (a) risk factors, (b) underlying mechanisms and (c) an intervention to reduce AIE. In an online experiment, 175 female BC patients were randomly assigned to one of three conditions. In the two experimental groups, patients were informed about the possible occurrence of cognitive problems after chemotherapy with (intervention group) or without (experimental group) reassuring information that 'there are still patients who score well on memory tests'. In the control group, no reference to chemotherapy-related cognitive problems was made. Main dependent measure was CPR. Four moderating and five mediating processes were examined. CPR increased with higher levels of stigma consciousness in the two experimental groups, but not in the no-information control group. Merely informing patients about cognitive side effects may increase their occurrence, especially among individuals vulnerable to patient stereotypes. Adding reassuring information is not sufficient to reduce AIE.

    Full Text Available Abstract Background In some hypertensive patients, psychological stress makes blood pressure difficult to control and causes physical symptoms such as headache or dizziness. We report the case of a hypertensive man whose psychological stress-induced increase in blood pressure was attenuated by cilnidipine. Case Presentation The patient (a 72-year-old man had hypertension and was on antihypertensive therapy. When mentally concentrating, he experienced occipital headaches and dizziness, and despite thorough testing, no abnormality was found. He was subsequently referred to our department. The mirror drawing test (MDT, a psychological stress test, increased blood pressure by about 40 mmHg, and the patient described occipital headache. Plasma noradrenaline level also increased from 212 to 548 pg/ml. We therefore switched the patient from nifedipine, an L-type calcium (Ca channel blocker, to cilnidipine, an L-type/N-type Ca channel blocker with suppressive effects on sympathetic activity. Cilnipidine attenuated MDT-induced an increase in blood pressure and plasma noradrenaline level and prevented the development of headache during testing. Conclusion These findings suggest that cilnidipine is a useful antihypertensive agent for hypertensive patients in whom psychological stress causes marked fluctuations in blood pressure.

  14. Negative Average Preference Utilitarianism

    Full Text Available For many philosophers working in the area of Population Ethics, it seems that either they have to confront the Repugnant Conclusion (where they are forced to the conclusion of creating massive amounts of lives barely worth living, or they have to confront the Non-Identity Problem (where no one is seemingly harmed as their existence is dependent on the “harmful” event that took place. To them it seems there is no escape, they either have to face one problem or the other. However, there is a way around this, allowing us to escape the Repugnant Conclusion, by using what I will call Negative Average Preference Utilitarianism (NAPU – which though similar to anti-frustrationism, has some important differences in practice. Current “positive” forms of utilitarianism have struggled to deal with the Repugnant Conclusion, as their theory actually entails this conclusion; however, it seems that a form of Negative Average Preference Utilitarianism (NAPU easily escapes this dilemma (it never even arises within it.

    This paper deals with prohibitive markers, i.e., negative markers that are more or less dedicated to the expression of a prohibition. It documents the variety in the formal make-up of these markers and it confims the earlier claims that they are frequent everywhere, with at least one exception, viz., Western Europe. Four origins are discussed:prohibitive markers may derive from predicative constructions, they may appear as a side product of Jespersen's cycle,they may derive from a univerbation of imperative and negative markers, and they may be borrowed. As explanation is offered as to why languages prefer to have prohibitive markers. It is argued that attempts to explain this preference in terms of morphosyntax are misguided. Instead a frequency-based semantic explanation is offered. The most frequent use of negatives are declarative, thereby inviting a static ‘it is not the case that' paraphrase. It is important, however, to mark clearly that prohibitives are instances of a dynamic ‘let it be the case that' appeal. The paper ends on a discussion of languages that do not employ prohibitive markers.

    Food preference describes the behavior of selecting between items for consumption; reinforcer effectiveness is the functional effect of that item in controlling behavior. Food preference and reinforcer effectiveness were examined in giant pandas (Ailuropoda melanoleuca) and African elephants (Loxodonta africana). A pairwise comparison between food items was used to assess food preference. High-, moderate-, and low-preference items were selected and tested for reinforcer effectiveness. High-preference items controlled behavior more effectively than less-preferred items. Caregiver ratings of food preferences were also collected for each subject, but these reports did not necessarily coincide with actual subject preferences. Caregiver ratings correlated with the food preferences of only 1 individual of each species; thus, preferences of 1 nonhuman animal may be falsely generalized to all animals of that species. Results suggest that food choice and reinforcer effectiveness should be investigated empirically and not rely on anecdotal reports.

    In the theories of team reasoning of Sugden and Bacharach, players are assumed to be motivated in some circumstances to maximize collective rather than individual utilities. An experiment was performed to assess whether preferences underlying such collective payoff maximization occur. An opportunistic sample of 50 undergraduate and graduate students, 7 men and 43 women ages 19 to 42 years (M= 23.0, SD=5.4), expressed preferences among the outcomes of strategic decisions presented in vignettes designed to engage social value orientations of individualism, altruism, competitiveness, equality seeking, or collective preferences. In the vignettes designed to engage collective preferences, and significantly less frequently in the other vignettes, preferences were biased toward outcomes maximizing collective payoffs, and respondents invariably gave team-reasoning explanations for their preferences. These results provide evidence for collective preferences according to theories of team reasoning and empirical support for one of the essential assumptions of these theories.

    Many have argued for the importance of continuing engineering education (CEE), but relatively few recommendations were found in the literature for how to use multimedia technologies to deliver it most effectively. The study reported here addressed this gap by investigating the multimedia category preferences of working engineers. Four categories of multimedia, with two types in each category, were studied: verbal (text and narration), static graphics (drawing and photograph), dynamic non-interactive graphics (animation and video), and dynamic interactive graphics (simulated virtual reality (VR) and photo-real VR). The results showed that working engineers strongly preferred text over narration and somewhat preferred drawing over photograph, animation over video, and simulated VR over photo-real VR. These results suggest that a variety of multimedia types should be used in the instructional design of CEE content.

    Teaching and learning activities in the dental clinic or hospital are a challenging area for students as well as teachers. With various teaching methodologies being used in dental schools around the world, gaining greater understanding of students' attitudes toward these methodologies would be useful for dental educators. The objective of this study was to explore the preferences of dental students in India about various aspects of lecture courses. A structured survey consisting of ten closed-ended questions was developed, and 2,680 undergraduate students from forty-three dental schools in India were approached via e-mail with a follow-up postal mailing. Of these, 1,980 students responded, for a response rate of 73.8 percent. Most of the students reported preferring lectures with the aid of PowerPoint and chalkboard. They preferred morning lectures from 8 am to 10 am for a maximum of thirty to forty minutes for each lecture, and they preferred to receive information about the lecture topic in advance. The students said that delivery of clinical demonstrations was beneficial after the lectures, and they preferred learning-based rather than exam-oriented education. The respondents also said that attendance should be made compulsory and that numerical marking of examinations should not be replaced by a grading system.

  20. Assessments of habitat preferences and quality depend on spatial scale and metrics of fitness

    1. Identifying the habitat features that influence habitat selection and enhance fitness is critical for effective management. Ecological theory predicts that habitat choices should be adaptive, such that fitness is enhanced in preferred habitats. However, studies often report mismatches between habitat preferences and fitness consequences across a wide variety of taxa based on a single spatial scale and/or a single fitness component. 2. We examined whether habitat preferences of a declining shrub steppe songbird, the Brewer's sparrow Spizella breweri, were adaptive when multiple reproductive fitness components and spatial scales (landscape, territory and nest patch) were considered. 3. We found that birds settled earlier and in higher densities, together suggesting preference, in landscapes with greater shrub cover and height. Yet nest success was not higher in these landscapes; nest success was primarily determined by nest predation rates. Thus landscape preferences did not match nest predation risk. Instead, nestling mass and the number of nesting attempts per pair increased in preferred landscapes, raising the possibility that landscapes were chosen on the basis of food availability rather than safe nest sites. 4. At smaller spatial scales (territory and nest patch), birds preferred different habitat features (i.e. density of potential nest shrubs) that reduced nest predation risk and allowed greater season-long reproductive success. 5. Synthesis and applications. Habitat preferences reflect the integration of multiple environmental factors across multiple spatial scales, and individuals may have more than one option for optimizing fitness via habitat selection strategies. Assessments of habitat quality for management prescriptions should ideally include analysis of diverse fitness consequences across multiple ecologically relevant spatial scales. ?? 2007 The Authors.

  1. Evidence for Menstrual Cycle Shifts in Women's Preferences for Masculinity: A Response to Harris (in Press “Menstrual Cycle and Facial Preferences Reconsidered”

    Directory of Open Access Journals (Sweden)

    2010-10-01

    Full Text Available Over the last decade, a growing literature has shown that women in the fertile phase of the menstrual cycle demonstrate stronger preferences for men with masculine traits than they do when in the non-fertile phases of the cycle (see Gangestad and Thornhill, 2008 and Jones et al., 2008 for recent reviews. In a recent article, Harris (in press; Sex Roles failed to replicate this increase in women's preferences for masculine faces when women are near ovulation. Harris represented her study as one of only three studies on the topic, and as the largest of the existing studies. There are, however, many more studies on menstrual cycle shifts in preferences for facial masculinity in the published literature, including one that is 2.5 times larger in size than the Harris study. In this article, we review the evidence for cyclic shifts in mate preferences and related behaviors and discuss weaknesses of Harris's methods. Considered as a whole, the evidence for menstrual cycle shifts in women's preferences and behaviors is compelling, despite the failure of replication reported by Harris.

    As the movement to capitalize on unique affordances of video games for learning continues to grow, relatively little research in that area has examined how formal features, such as genre and game mechanics, draw and hold children's attention. This study examines which genres children prefer and the reasons why children prefer those genres by reporting on a video game uses and gratifications survey of children of various ages (n=685). Results show distinct patterns of game use and preference tied to typical child developmental ecology at each age, indicating that genre preference varies by age and developmental context. Implications for game research and educational gaming are provided.

    Full Text Available Abstract Background The importance of respecting patients’ preferences when making treatment decisions is increasingly recognized. Efficiently retrieving papers from the scientific literature reporting on the presence and nature of such preferences can help to achieve this goal. The objective of this study was to create a search filter for PubMed to help retrieve evidence on patient preferences for treatment outcomes. Methods A total of 27 journals were hand-searched for articles on patient preferences for treatment outcomes published in 2011. Selected articles served as a reference set. To develop optimal search strategies to retrieve this set, all articles in the reference set were randomly split into a development and a validation set. MeSH-terms and keywords retrieved using PubReMiner were tested individually and as combinations in PubMed and evaluated for retrieval performance (e.g. sensitivity (Se and specificity (Sp. Results Of 8238 articles, 22 were considered to report empirical evidence on patient preferences for specific treatment outcomes. The best search filters reached Se of 100 % [95 % CI 100-100] with Sp of 95 % [94–95 %] and Sp of 97 % [97–98 %] with 75 % Se [74–76 %]. In the validation set these queries reached values of Se of 90 % [89–91 %] with Sp 94 % [93–95 %] and Se of 80 % [79–81 %] with Sp of 97 % [96–96 %], respectively. Conclusions Narrow and broad search queries were developed which can help in retrieving literature on patient preferences for treatment outcomes. Identifying such evidence may in turn enhance the incorporation of patient preferences in clinical decision making and health technology assessment.

    Excessive exposure to high-salt foods may change the taste perception, which results in the overconsumption of sodium. The present study aimed to investigate the effects of liking or frequent eating of high-salt food on salt taste perception among schoolchildren. The detection threshold of sodium chloride (NaCl) and the preferred salinity of beansprout soup were determined and were used to represent the salt taste acuity and preference, respectively, of 70 Koreans aged 12-13 years. A self-administered questionnaire was used to obtain information regarding food preferences or frequency of eating certain high-salt Korean dishes, Westernised fast foods and commercially-prepared foods, as well as various food groups. The significance of differences in taste perceptions was assessed in relation to the reported liking, and frequency of eating, high-salt foods. In addition, the correlation between taste perception and the liking or frequency of eating fast foods was also assessed. The participants who reported a liking for soup/stew had significantly higher thresholds for NaCl (P = 0.029), and frequent users of fast-food restaurants showed a preference for significantly saltier soup (P = 0.010). The preferred salinity was associated significantly with a high preference for pizza (r = 0.282, P = 0.018) or hamburgers (r = 0.305, P = 0.010) and the frequent consumption of pork cutlets (r = 0.239, P = 0.046) or hamburgers (r = 0.461, P = 0.010). The results obtained in the present study suggest that the frequent consumption of certain fast foods by young teenagers may be associated with an increased preference for salt taste. This study provides basic information for use in devising education programmes in evidence-based nutrition to reduce salt intake.

    The idea that decisions alter preferences has had a considerable influence on the field of psychology and underpins cognitive dissonance theory. Yet it is unknown whether choice-induced changes in preferences are long lasting or are transient manifestations seen in the immediate aftermath of decisions. In the research reported here, we investigated whether these changes in preferences are fleeting or stable. Participants rated vacation destinations before making hypothetical choices between destinations, immediately afterward, and 2.5 to 3 years later. We found that choices altered preferences both immediately after being made and after the delay. These changes could not be accounted for by participants' preexisting preferences, and they occurred only when participants made the choices themselves. Our findings provide evidence that making a decision can lead to enduring change in preferences.

  12. The Effect of Answering in a Preferred Versus a Non-Preferred Survey Mode on Measurement

    2014-12-01

    Full Text Available Previous research has shown that offering respondents their preferred mode can increase response rates, but the effect of doing so on how respondents process and answer survey questions (i.e., measurement is unclear. In this paper, we evaluate whether changes in question format have different effects on data quality for those responding in their preferred mode than for those responding in a non-preferred mode for three question types (multiple answer, open-ended, and grid. Respondents were asked about their preferred mode in a 2008 survey and were recontacted in 2009. In the recontact survey, respondents were randomly assigned to one of two modes such that some responded in their preferred mode and others did not. They were also randomly assigned to one of two questionnaire forms in which the format of individual questions was varied. On the multiple answer and open-ended items, those who answered in a non-preferred mode seemed to take advantage of opportunities to satisfice when the question format allowed or encouraged it (e.g., selecting fewer items in the check-all than the forced-choice format and being more likely to skip the open-ended item when it had a larger answer box, while those who answered in a preferred mode did not. There was no difference on a grid formatted item across those who did and did not respond by their preferred mode, but results indicate that a fully labeled grid reduced item missing rates vis-à-vis a grid with only column heading labels. Results provide insight into the effect of tailoring to mode preference on commonly used questionnaire design features.

    The aim of this study was to assess the impact of meta-cognitive training (MCT) on cognitive biases, symptoms, clinical insight, and general functioning among low-level functioning persons diagnosed with chronic schizophrenia who were attending a daily Community Social Support Group Program; we compared the treatment-as-usual (TAU) condition with the MCT + TAU condition. Forty-four patients diagnosed with chronic schizophrenia were allocated to either the MCT + treatment-as-usual condition or the treatment-as-usual (TAU) condition. Delusion and hallucination severity, cognitive biases, clinical insight, and global functioning were assessed pre- and post-treatment (clinical trial NCT02187692). No significant changes were found in symptom severity as measured with the PSYRATS. Conversely, a medium to large effect size was observed for delusional ideation changes when assessed by the self-report measure (Paranoia Checklist). MCT was found to ameliorate cognitive biases as measured by the self-report scale at large effect size, however, no changes in jumping to conclusions (the Fish Task) and theory of mind deficits ("Reading the Mind in the Eyes" Test) were found in the behavioral tasks. MCT increased insight at large effect size. No changes in global functioning were found between the two conditions. Low intensity intervention. No follow-up assessment was provided. Only PSYRATS was assessed blind to patient allocation. MCT has a beneficial effect on low-functioning chronic schizophrenic patients in ameliorating cognitive biases and increasing clinical insight.

    The present research focused on gender differences in career preferences, comparing those in 2010 with those in 1990 (as reported by Gati, Osipow, & Givon, 1995). The tested hypothesis was that gender differences in aspect-based career preferences (e.g., income, teamwork, professional advancement, length of training) would have decreased over the past 20 years. The career preferences of 21,767 young adult women and 15,532 men-who used an Internet-based career guidance system in 2010 to assist them in making a career decision-were analyzed and compared with the respective preferences of 1,252 young adult women and 751 young adult men who used a previous version of the system in 1990. As hypothesized, gender differences were attenuated in most aspects (e.g., professional advancement, management); however, these differences increased in a few aspects (e.g., community service and counseling are increasingly preferred by women). The findings and their implications are discussed. (c) 2014 APA, all rights reserved.

    A role for circadian rhythm abnormalities in the pathogenesis of bipolar disorder (BD) has been suggested. The present study assessed circadian preference, a subjective preference for activities in the morning or evening related to chronotype. The sample was comprised of 81 outpatients with BD in remission and 79 control subjects. Circadian preference was derived from an interview evaluating biological rhythms and sleep pattern from the Pittsburgh Sleep Quality Index. Patients were significantly more likely to have an evening preference than control subjects. Circadian preference was also associated with sleep latency. The association of evening preference and longer sleep latency may be related to the frequent clinical observation of a sleep/wake cycle reversal in bipolar disorder.

    1980-08-01

    It has been reported that certain tetrahydroisoquinoline compounds, especially salsolinol and tetrahydropaveroline (THP) when infused into the lateral ventricle of rats' brains results in increased preference for alcohol solutions. The effect is reported to be long-term, in that animals do not return to baseline drinking even months later. The current report provides a replicatin of the original experiments and also an extension of the work to complete dose-response curves for salsolinol and THP. Generally we have confirmed that rats of the Sprague-Dawley and Long-Evans strains do increase their alcohol intake in response to infused THP or salsolinol and that the effect is long lasting, up to 10 months. Such animals consume less alcohol at concentrations above 20% than below, in contrast to the previous reports where drinking was maintained at high concentrations of alcohol. While the animals will select alcohol in the face of a saccharin choice, they will not drink alcohol adulterated with quinine. We have failed to observe signs of dependence or withdrawal by these techniques and suggest that the original reports of these signs may have been a result of cellular damage caused by the long-term infusions. Additionally we have carried out extensive dose-response experiments with both salsolinol and THP. Doses of THP of 104 nmoles/day were inhibitory to alcohol drinking. We conclude that these compounds do shift these animals preference for alcohol relatively permanently, but not to the point of gross intoxication nor into the highly aversive range of alcohol concentration. We cannot confirm the reports that salsolinol or THP produce withdrawal symptoms when infused.

    With the increasing popularity of location-based social media applications and devices that automatically tag generated content with locations, large repositories of collaborative geo-referenced data are appearing on-line. Efficiently extracting user preferences from these data to determine what information to recommend is challenging because of the sheer volume of data as well as the frequency of updates. Traditional recommender systems focus on the interplay between users and items, but ignore contextual parameters such as location. In this paper we take a geospatial approach to determine locational preferences and similarities between users. We propose to capture the geographic context of user preferences for items using a relational graph, through which we are able to derive many new and state-of-the-art recommendation algorithms, including combinations of them, requiring changes only in the definition of the edge weights. Furthermore, we discuss several solutions for cold-start scenarios. Finally, we con...

    The degree to which non-human primate behavior is lateralized, at either individual or population levels, remains controversial. We investigated the relationship between hand preference and posture during tool use in chimpanzees (Pan troglodytes) during bipedal tool use. We experimentally induced...... tool use in a supported bipedal posture, an unsupported bipedal posture, and a seated posture. Neither bipedal tool use nor these supported conditions have been previously evaluated in apes. The hypotheses tested were 1) bipedal posture will increase the strength of hand preference, and 2) a bipedal...... stance, without the use of one hand for support, will elicit a right hand preference. Results supported the first, but not the second hypothesis: bipedalism induced the subjects to become more lateralized, but not in any particular direction. Instead, it appears that subtle pre-existing lateral biases...

    AIM To report the first international living related two way kidney paired donation (KPD) transplantation from India which occurred on 17th February 2015 after legal permission from authorization committee. METHODS Donor recipient pairs were from Portugal and India who were highly sensitized and ABO incompatible with their spouse respectively. The two donor recipient pairs had negative lymphocyte cross-matching, flow cross-match and donor specific antibody in two way kidney exchange with the intended KPD donor. Local KPD options were fully explored for Indian patient prior to embarking on international KPD. RESULTS Both pairs underwent simultaneous uneventful kidney transplant surgeries and creatinine was 1 mg/dL on tacrolimus based immunosuppression at 11 mo follow up. The uniqueness of these transplantations was that they are first international KPD transplantations in our center. CONCLUSION International KPD will increases quality and quantity of living donor kidney transplantation. This could be an important step to solving the kidney shortage with additional benefit of reduced costs, improved quality and increased access for difficult to match incompatible pairs like O blood group patient with non-O donor and sensitized patient. To the best of our knowledge this is first international KPD transplantation from India. PMID:28280697

  20. Reversal of an Unconditioned Behavioral Preference for Specific Food Pellets by Intervention of Whisker Sensory Inputs.

    Adenylyl cyclase type-5 (AC5) is preferentially expressed in the dorsal striatum. Recently, we reported that AC5 knockout (KO) mice preferred food pellets carrying an olfactory cue produced by AC5 KO mice during food consumption (AC5 KO pellets) over food pellets that had been taken by wildtype (WT) mice. In the present study, we demonstrated that whisker trimming on the right side of the face but not the left in AC5 KO mice blocked the behavioral preference for AC5 KO pellets. Conversely, whisker trimming on the right but not the left in WT mice induced a behavioral preference for AC5 KO pellets. Mice lacking D2 dopamine receptor (D2 KO mice) also showed a behavioral preference for AC5 KO pellets. In D2 mice, whisker trimming on the right side of the face but not the left blocked a behavioral preference for AC5 KO food pellets. AC5 KO mice had increased level of phospho-CaMKIIα in the dorsal striatum, and WT mice with whiskers cut on either side also showed increased p-CaMKIIα level in the dorsal striatum. The siRNA-mediated inhibition of CaMKIIα in the dorsal striatum in either the right or the left hemisphere in AC5 KO mice and D2 KO mice blocked the behavioral preference for AC5 KO pellets. However, behavioral changes induced by this inhibition on each side showed asymmetrical time courses. These results suggest that an unconditioned behavioral preference for specific food pellets can be switched on or off based on the balance of states of neural activity in the dorsal striatum regulated by a signaling pathway centered on AC5 and D2 and the sensory inputs of whiskers from the right side of the face.

On the basis of both these political preferences and ecological constraints, individuals then make rational choices about the desirability of secession. Instrumental considerations are therefore...... that cultural identities matter for explaining secessionism, but not because of primordial attachments. Rather, religious and linguistic groups matter because their members are imbued with cultural legacies that lead to distinct political preferences – in this case preferences over welfare statism.

  2. Preference for sons: past and present.

    Science.gov (United States)

    Li, D

    1997-10-01

    This brief article discusses the present and past preference for sons in China. The preference for sons is rooted in feudal views that men are superior to women. Preference for sons dates back to the Warring States Period, in about 500 B.C. Clan brotherhoods of men have existed for centuries. Historical records mention the practice of female infanticide. Patriarchal families believed that women were economically dependent on men and thus became their subjects. Daughters married, lived in their husband's home, and did not carry the responsibility of caring for their own parents. Couples with only daughters would seek a son-in-law to support them in old age. Rural families with no sons were looked down upon. Sons were expected to carry on the family lineage, increase the reputation of the family, and protect the family's interests. The lack of sons was a sign of humiliation and a curse. The founding of the People's Republic of China brought changes to son preference. The government attempted to increase women's status. In rural areas, women were given equal access to the land. Job opportunities were created for women during the industrialization drive. The Chinese government encouraged the repudiation of the negative impacts of the doctrines of Confucius and Mencius. Efforts were made to give men and women equal pay for equal work. Legislation was passed prohibiting arranged marriage, polygyny, and early marriage. A side effect of fertility decline is the renewed preference for sons. In Huangyan and Haining in Zhejiang, a developed province, the sex ratio at birth is normal. Sexual division of labor reinforces son preference.

  3. Preference formation and institutional change

    Directory of Open Access Journals (Sweden)

    Sérgio Praça

    2009-06-01

    Full Text Available This essay critically analyses how historical institutionalists and rational choice scholars study institutional stability and change. Special attention is paid to the thorny issued of how political actors’ preferences are formed, with historical institutionalists considering preferences as endogenously formed, and rational choice analysts postulating that preferences are fixed and exogenous. An argument is made in favour of the perspective that considers preferences as being formed within the functioning of the political system over time, endogenously. The essay also proposes the incorporation of ideas and non-decisions as tools to elucidate processes of change.

    Over the past few decades, beef producers in Japan have improved marbling in their beef products. It was recently reported that marbling is not well correlated with palatability as rated by Japanese consumers. This study sought to identify the consumer segments in Japan that prefer sensory characteristics of beef other than high marbling. Three Wagyu beef, one Holstein beef and two lean imported beef longissimus samples were subjected to a descriptive sensory test, physicochemical analysis and a consumer (n = 307) preference test. According to consumer classification and external preference mapping, four consumer segments were identified as 'gradual high-fat likers', 'moderate-fat and distinctive taste likers', 'Wagyu likers' and 'distinctive texture likers'. Although the major trend of Japanese consumers' beef preference was 'marbling liking', 16.9% of the consumers preferred beef samples that had moderate marbling and distinctive taste. The consumers' attitudes expressed in a questionnaire survey were in good agreement with the preference for marbling among the 'moderate-fat and distinctive taste likers'. These results indicate that moderately marbled beef is a potent category in the Japanese beef market. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

  6. Distinctive Klf4 mutants determine preference for DNA methylation status

    Reprogramming of mammalian genome methylation is critically important but poorly understood. Klf4, a transcription factor directing reprogramming, contains a DNA binding domain with three consecutive C2H2 zinc fingers. Klf4 recognizes CpG or TpG within a specific sequence. Mouse Klf4 DNA binding domain has roughly equal affinity for methylated CpG or TpG, and slightly lower affinity for unmodified CpG. The structural basis for this key preference is unclear, though the side chain of Glu446 is known to contact the methyl group of 5-methylcytosine (5mC) or thymine (5-methyluracil). We examined the role of Glu446 by mutagenesis. Substituting Glu446 with aspartate (E446D) resulted in preference for unmodified cytosine, due to decreased affinity for 5mC. In contrast, substituting Glu446 with proline (E446P) increased affinity for 5mC by two orders of magnitude. Structural analysis revealed hydrophobic interaction between the proline's aliphatic cyclic structure and the 5-methyl group of the pyrimidine (5mC or T). As in wild-type Klf4 (E446), the proline at position 446 does not interact directly with either the 5mC N4 nitrogen or the thymine O4 oxygen. In contrast, the unmethylated cytosine's exocyclic N4 amino group (NH2) and its ring carbon C5 atom hydrogen bond directly with the aspartate carboxylate of the E446D variant. Both of these interactions would provide a preference for cytosine over thymine, and the latter one could explain the E446D preference for unmethylated cytosine. Finally, we evaluated the ability of these Klf4 mutants to regulate transcription of methylated and unmethylated promoters in a luciferase reporter assay.

    Melanocortin-4-receptor (MC4R)-expressing neurons modulate food intake and preference in rodents but their role in human food preference is unknown. Here we show that compared with lean and weight-matched controls, MC4R deficient individuals exhibited a markedly increased preference for high fat, but a significantly reduced preference for high sucrose food. These effects mirror those in Mc4r null rodents and provide evidence for a central molecular circuit influencing human macronutrient preference. PMID:27701398

    These studies examined the relationship between salt preference of adult offspring and their mothers' symptoms of morning sickness during pregnancy. College students who could provide information about their mothers' symptoms of morning sickness completed a survey about their dietary salt intake (study 1; n = 169) or rated and consumed ten snack foods (study 2; n = 66). In study 1 a salt-use score was calculated based on responses to the Salt Intake Questionnaire; offspring of women with moderate or severe vomiting reported a significantly higher level of salt use (p < 0.01) than those whose mothers report little or no symptoms. In study 2 saltiness and pleasantness ratings of high-salt foods, intake of those foods and total sodium intake were the focus of analysis. Offspring of women reporting moderate or severe vomiting showed a significantly greater preference for the snack food subjects rated as saltiest than those whose mothers reported no or mild vomiting. They also ate more of that food and consumed more total sodium during the test session. Effects were stronger in Caucasian than Asian subjects. These studies suggest that moderate to severe vomiting during pregnancy can be associated with significantly higher salt intake in offspring. Thus, a gestational event may be an important determinant of salt intake and preference in adulthood.

    Full Text Available Abstract Background Due to the low participation in colorectal cancer screening, public preference for colorectal cancer screening modality was determined. Methods A cross-sectional survey was performed of healthy ambulatory adults in a pediatrics primary care office and neighboring church. Overall preference was ranked for each of four colorectal cancer screening modalities: Faecal Occult Blood, Fiberoptic Sigmoidoscopy, Barium Enema and Colonoscopy. Four additional domains of preference also were ranked: suspected discomfort, embarrassment, inconvenience and danger of each exam. Results 80 surveys were analyzed, 57 of which were received from participants who had experienced none of the screening tests. Fecal Occult Blood Testing is significantly preferred over each other screening modality in overall preference and every domain of preference, among all subjects and those who had experienced none of the tests. Conclusions Efforts to increase public participation in colorectal cancer screening may be more effective if undertaken in the context of public perceptions of screening choices.

    To collect normative data, assess differences between demographic groups, and indirectly compare US and Canadian medical systems relative to patient expectations of involvement in cancer treatment decision making. Meta-analysis. Individual patient data were compiled across 6 clinical studies among 3491 patients with cancer who completed the 2-item Control Preferences Scale indicating the roles they preferred versus actually experienced in treatment decision making. The roles in treatment decision making that patients preferred were 26% active, 49% collaborative, and 25% passive. The roles that patients reported actually experiencing were 30% active, 34% collaborative, and 36% passive. Roughly 61% of patients reported having their preferred role; only 6% experienced extreme discordance between their preferred versus actual roles. More men than women (66% vs 60%, P = .001) and more US patients than Canadian patients (84% vs 54%, P roles. More Canadian patients than US patients preferred and actually experienced (42% vs 18%, P roles. More women than men reported taking a passive role (40% vs 24%, P role. Roughly half of the studied patients with cancer indicated that they preferred to have a collaborative relationship with physicians. Although most patients had the decision-making role they preferred, about 40% experienced discordance. This highlights the need for incorporation of individualized patient communication styles into treatment plans.

    Full Text Available Background. The goal of advance directives is to help patients retain their dignity and autonomy by making their own decisions regarding end-stage medical treatment. The purpose of this study was to examine preferences of advance directives among general population in Korea. Method. A descriptive cross-sectional survey was performed from October 2007 to June 2008 in Seoul, Korea. A total of 336 city-dwelling adults self-administered the questionnaire and returned it via mail. Data analyses were conducted using SPSS 17.0. Results. Subjects reported the need for healthcare providers' detailed explanations and recommendations regarding end-of-life care. When there is no hope of recovery and death is imminent, most subjects did not want to receive cardiopulmonary resuscitation nor an IV or tube feeding. However, most of the subjects wanted pain management care. Conclusions. The present study showed that many Korean people have an interest in advance directives. The results show that the autonomy and dignity of patient have increased in importance. To provide better end-of-life care, there is a need to educate patients on the definition and intent of an advance directive. Additional proactive communication between patients and their caregivers should be educated to healthcare providers.

    Fairness is one of the most important foundations of morality and may have played a key role in the evolution of cooperation in humans beings. As an important type of fairness concern, inequity aversion is the preference for fairness and the resistance to inequitable outcomes. To examine the early development of fairness preference in young children, sixty 2- and 3-year-old children were recruited to examine young children's preferences for fairness using a forced choice paradigm. We tested how toddlers acted when they took charge of distributing resources (two candies) to themselves and others and when they were the recipients of both other-advantageous distribution and self-advantageous distribution. Different alternative options were paired with the same fair option in the two conditions. In the other-advantageous condition, children had fewer resources in the alternative options than others, whereas their resources in the alternative options were greater than others' in the self-advantageous condition. The results showed that more children displayed fairness preferences when they distributed resources between two friends than when they distributed resources between a friend and themselves. In both scenarios, 3-year-old children were more likely to demonstrate fairness preference than 2-year-old children. The findings suggest that inequity aversion develops in young children and increases with age over the course of early childhood. When they were recipients, there was a trend in young children's preference for fairness in the other-advantageous condition compared with the self-advantageous condition. This suggests that children might tend to be more likely to display inequity aversion when they are in a disadvantageous position.

    A quasi-experimental study was conducted to evaluate the influence of Project CHEF, a hands-on cooking and tasting program offered in Vancouver public schools, on students' food preferences, cooking skills, and confidence. Grade 4 and 5 students in an intervention group (n = 68) and a comparison group (n = 32) completed a survey at baseline and 2 to 3 weeks later. Students who participated in Project CHEF reported an increased familiarity and preference for the foods introduced through the program. This was statistically significant (P ≤ 0.05) for broccoli, swiss chard, carrots, and quinoa. A higher percentage of students exposed to Project CHEF reported a statistically significant increase (P ≤ 0.05) in: cutting vegetables and fruit (97% vs 81%), measuring ingredients (67% vs 44%), using a knife (94% vs 82%), and making a balanced meal on their own (69% vs 34%). They also reported a statistically significant increase (P ≤ 0.05) in confidence making the recipes introduced in the program: fruit salad (85% vs 81%), minestrone soup (25% vs 10%), and vegetable tofu stir fry (39% vs 26%). Involving students in hands-on cooking and tasting programs can increase their preferences for unpopular or unfamiliar foods and provide them with the skills and cooking confidence they need to prepare balanced meals.

  3. Preference patterns in infant vowel perception

    Molnar, Monika T.; Polka, Linda

    2001-05-01

    Infants show directional asymmetries in vowel discrimination tasks that reveal an underlying perceptual bias favoring more peripheral vowels. Polka and Bohn (2003) propose that this bias is language independent and plays an important role in the development of vowel perception. In the present study we measured infant listening preferences for vowels to assess whether a perceptual bias favoring peripheral vowels can be measured more directly. Monolingual (French and English) and bilingual infants completed a listening preference task using multiple natural tokens of German /dut/ and /dyt/ produced by a male talker. In previous work, discrimination of this vowel pair by German-learning and by English-learning infants revealed a robust directional asymmetry in which /u/ acts as a perceptual anchor; specifically, infants had difficulty detecting a change from /u/ to /y/, whereas a change from /y/ to /u/ was readily detected. Preliminary results from preference tests with these stimuli show that most infants between 3 and 5 months of age also listen longer to /u/ than to /y/. Preference data obtained from older infants and with other vowel pairs will also be reported to further test the claim that peripheral vowels have a privileged perceptual status in infant perception.

  4. Behavioral and molecular analysis of nicotine-conditioned place preference in zebrafish.

    Directory of Open Access Journals (Sweden)

    Ximena Kedikian

    Full Text Available Studies using mice and rats have demonstrated that nicotine induces a conditioned place preference (CPP, with more effective results obtained by using biased procedures. Zebrafish have also been used as a model system to identify factors influencing nicotine-associated reward by using an unbiased design. Here, we report that zebrafish exhibited putative nicotine biased CPP to an initially aversive compartment (nicotine-paired group. A counterbalanced nicotine-exposed control group did not show a significant preference shift, providing evidence that the preference shift in the nicotine-paired group was not due to a reduction of aversion for this compartment. Zebrafish preference was corroborated by behavioral analysis of several indicators of drug preference, such as time spent in the drug-paired side, number of entries to the drug-paired side, and distance traveled. These results provided strong evidence that zebrafish may actually develop a preference for nicotine, although the drug was administrated in an aversive place for the fish, which was further supported by molecular studies. Reverse transcription-quantitative real-time PCR analysis depicted a significant increase in the expression of α7 and α6 but not α4 and β2 subunits of the nicotinic receptor in nicotine-paired zebrafish brains. In contrast, zebrafish brains from the counterbalanced nicotine group showed no significant changes. Moreover, CREB phosphorylation, an indicator of neural activity, accompanied the acquisition of nicotine-CPP. Our studies offered an incremental value to the drug addiction field, because they further describe behavioral features of CPP to nicotine in zebrafish. The results suggested that zebrafish exposed to nicotine in an unfriendly environment can develop a preference for that initially aversive place, which is likely due to the rewarding effect of nicotine. Therefore, this model can be used to screen exogenous and endogenous molecules involved in

    We studied the factors that predict liking for vegetables and preference for a variety of vegetables among schoolchildren. Additionally, we examined if there were gender differences in the predictors that explain the hypothesized higher scores in liking vegetables and preferences among girls. The data from the PRO GREENS project included 424 Finnish children (response rate 77%) aged 11 to 12. The children completed validated measures about social and environmental factors related to their liking for vegetables and preferences both at baseline 2009 and follow-up 2010. The associations were examined with regression and mediation analyses. The strongest predictors of both girls' and boys' liking and preferences were higher levels of eating vegetables together with the family, previous vegetable intake and a lower level of perceived barriers. Liking was additionally predicted by a lower level of parental demand that their child should eat vegetables. Girls reported higher levels of liking and preferences in the follow-up. This gender difference was mainly explained by girls' lower level of perceived barriers related to vegetable intake and girls' higher previous vegetable intake. Interventions that aim to increase the low vegetable intake among boys by increasing their liking for vegetables and preference for a variety of vegetables could benefit from targeting perceived barriers, namely boys' perception and values concerning the consumption of vegetables.

    This pilot study investigated the relationship between sugar consumption/ preference and the length of residence in the U.S. among certain immigrant groups. The study sample consisted of 213 volunteers from community organizations and church groups, of Nigerian (45%), Mexican (31%), and Chinese (24%) descent. Data were collected on demographics, sugar consumption/preference (24-hour dietary recall), and oral health status. The age of respondents varied from 18 to 93 years with a mean age of 37.0 ± 11.7 years. The mean length of residence was 9.2 ± 7.2 years, and the mean sugar consumption was 122.4 ± 114.6 g/day. Immigrants from Mexico and Nigeria reported consuming more servings of sweets per day than the Chinese (p= .006); Mexican immigrants had the highest level of sugar preference (p= .001). No significant differences were observed between the length of residence and either sugar consumption or sugar preference. Greater availability of sugar and sweet snacks does not always result in increased sugar consumption or sugar preference.

    .003) and a trend toward worsening scores in 4 other domains was observed; however, Patient Satisfaction scores remained unchanged. Lowest instrumented vertebrae and surgical approach could not be correlated to changes in the pain score. In addition, no correlation was found between changes in any of the 21 radiographic measures evaluated and changes in SRS scores. There was a statistically significant increase in reported pain from 2 to 5 years after surgical treatment; however, the etiology of worsening pain scores could not be elucidated. Given continued patient satisfaction, the clinical relevance of this small reduction remains unknown. Nevertheless, this observation deserves further evaluation and must be considered in relation to the natural history of this disease.

These therapies, however, increase risk of adverse bleeding events. We assessed patient-reported trade-offs between cardioprotective benefit, gastrointestinal bleeding risk, and burden of self-management using adaptive conjoint analysis (ACA. As ACA could be a clinically useful tool to obtain patient preferences and guide future patient-centered care, we examined the clinical application of ACA to obtain patient preferences and the impact of ACA on medication adherence.Patients and methods: An electronic ACA survey led 201 respondents through medication risk–benefit trade-offs, revealing patients’ preferences for the CAT risk/benefit profile they valued most. The post-ACA prescription regimen was categorized as concordant or discordant with elicited preferences.

    PRISMA statement was published in 2009 in order to set standards in the reporting of systematic reviews and meta-analyses. Our aim was to evaluate the impact of PRISMA endorsement on the quality of reporting and methodological quality of systematic reviews and meta-analyses, published in journals in the field of gastroenterology and hepatology (GH). Quality of reporting and methodological quality were evaluated by assessing the adherence of papers to PRISMA checklist and AMSTAR quality scale. After identifying the GH journals which endorsed PRISMA in instructions for authors (IA), we appraised: 15 papers published in 2012 explicitly mentioning PRISMA in the full text (Group A); 15 papers from the same journals published in 2012 not explicitly mentioning PRISMA in the full text (Group B); 30 papers published the year preceding PRISMA endorsement from the same journals as above (Group C); 30 papers published in 2012 on the 10 highest impact factor journals in GH which not endorsed PRISMA (Group D). PRISMA statement was referred in the IA in 9 out of 70 GH journals (12.9%). We found significant increase in overall adherence to PRISMA checklist (Group A, 90.1%; Group C, 83.1%; p = 0.003) and compliance to AMSTAR scale (Group A, 85.0%; Group C, 74.6%; p = 0.002), following the PRISMA endorsement from the nine GH journals. Explicit referencing of PRISMA in manuscript was not associated with increase in quality of reporting and methodological quality (Group A vs. B, p = 0.651, p = 0.900, respectively). Adherence to PRISMA checklist, and the compliance with AMSTAR were significantly higher in journals endorsing PRISMA compared to those not (Groups A+B vs. D; p = 0.003 and p = 0.016, respectively). The endorsement of PRISMA resulted in increase of both quality of reporting and methodological quality. It is advised that an increasing number of medical journals include PRISMA in the instructions for authors.

    Current work in planning with preferences assume that the user's preference models are completely specified and aim to search for a single solution plan. In many real-world planning scenarios, however, the user probably cannot provide any information about her desired plans, or in some cases can only express partial preferences. In such situations, the planner has to present not only one but a set of plans to the user, with the hope that some of them are similar to the plan she prefers. We first propose the usage of different measures to capture quality of plan sets that are suitable for such scenarios: domain-independent distance measures defined based on plan elements (actions, states, causal links) if no knowledge of the user's preferences is given, and the Integrated Convex Preference measure in case the user's partial preference is provided. We then investigate various heuristic approaches to find set of plans according to these measures, and present empirical results demonstrating the promise of our app...

    The use of computer-mediated communication (CMC) as a form of social interaction has become increasingly prevalent, yet few studies examine individual differences that may shed light on implications of CMC for adjustment. The current study examined neurocognitive individual differences associated with preferences to use technology in relation to social-emotional outcomes. In Study 1 (N = 91), a self-report measure, the Social Media Communication Questionnaire (SMCQ), was evaluated as an assessment of preferences for communicating positive and negative emotions on a scale ranging from purely via CMC to purely face-to-face. In Study 2, SMCQ preferences were examined in relation to event-related potentials (ERPs) associated with early emotional attention capture and reactivity (the frontal N1) and later sustained emotional processing and regulation (the late positive potential (LPP)). Electroencephalography (EEG) was recorded while 22 participants passively viewed emotional and neutral pictures and completed an emotion regulation task with instructions to increase, decrease, or maintain their emotional responses. A greater preference for CMC was associated with reduced size of and satisfaction with social support, greater early (N1) attention capture by emotional stimuli, and reduced LPP amplitudes to unpleasant stimuli in the increase emotion regulatory task. These findings are discussed in the context of possible emotion- and social-regulatory functions of CMC.

    Given that funds for biodiversity conservation are limited, there is a need to understand people's preferences for its different components. To date, such preferences have largely been measured in monetary terms. However, how people value biodiversity may differ from economic theory, and there is little consensus over whether monetary metrics are always appropriate or the degree to which other methods offer alternative and complementary perspectives on value. We used a choice experiment to compare monetary amounts recreational visitors to urban green spaces were willing to pay for biodiversity enhancement (increases in species richness for birds, plants, and aquatic macroinvertebrates) with self-reported psychological gains in well-being derived from visiting the same sites. Willingness-to-pay (WTP) estimates were significant and positive, and respondents reported high gains in well-being across 3 axes derived from environmental psychology theories (reflection, attachment, continuity with past). The 2 metrics were broadly congruent. Participants with above-median self-reported well-being scores were willing to pay significantly higher amounts for enhancing species richness than those with below-median scores, regardless of taxon. The socio-economic and demographic background of participants played little role in determining either their well-being or the probability of choosing a paying option within the choice experiment. Site-level environmental characteristics were only somewhat related to WTP, but showed strong associations with self-reported well-being. Both approaches are likely to reflect a combination of the environmental properties of a site and unobserved individual preference heterogeneity for the natural world. Our results suggest that either metric will deliver mutually consistent results in an assessment of environmental preferences, although which approach is preferable depends on why one wishes to measure values for the natural world. © 2013 The

    Terry Bazzarre

    2003-12-01

    Full Text Available On May 1, 2001, a coalition of national organizations released a major planning document designed to develop a national strategy for the promotion of physically active lifestyles among the mid-life and older adult population. The National Blueprint: Increasing Physical Activity Among Adults Age 50 and Older was developed with input from 46 organizations with expertise in health, medicine, social and behavioral sciences, epidemiology, gerontology/geriatrics, clinical science, public policy, marketing, medical systems, community organization, and environmental issues. The Blueprint notes that, despite a wealth of evidence about the benefits of physical activity for mid-life and older persons, there has been little success in convincing age 50+ Americans to adopt physically active lifestyles. The Blueprint identifies barriers in the areas of research, home and community programs, medical systems, public policy and advocacy, and marketing and communications. In addition to identifying barriers, the Blueprint proposes a number of concrete strategies that could be employed in order to overcome the barriers to physical activity in society at large. This report summarizes the outcome of the National Blueprint Consensus Conference that was held in October 2002. In this conference, representatives of more than 50 national organizations convened in Washington, D.C. with the goal of identifying high priority and high feasibility strategies which would advance the National Blueprint and which could be initiated within the next 12 to 24 months. Participants in the consensus conference were assigned to one of five breakout groups: home and community, marketing, medical systems, public policy, and research. Each breakout group was charged with identifying the three highest priority strategies within their area for effectively increasing physical activity levels in the mid-life and older adult population. In addition to the 15 strategies identified by the

  3. Early Menarche is Associated With Preference for Masculine Male Faces and Younger Preferred Age to Have a First Child

    Directory of Open Access Journals (Sweden)

    2016-04-01

    Full Text Available One developmental factor that is associated with variation in reproductive strategy is pubertal timing. For instance, women who experience earlier menarche have their first pregnancy earlier and prefer more masculinized male voices. Early menarche may also lead to preferences for masculine faces, but no study has shown such a link. We therefore investigated the relationships between pubertal timing, reproductive plans, sexual attitudes and behaviors, and masculinity preferences in nulliparous women aged 18–30 from the United Kingdom (N = 10,793. We found that women who experienced earlier menarche reported a younger preferred age to have a first child and showed stronger masculinity preferences. This provides evidence that women experiencing early menarche not only have children earlier but notably plan to have children earlier. Additionally, our findings provide evidence that age of menarche influences partner selection, which is instrumental for the implementation of reproductive strategies.

  5. Novelty vs. familiarity principles in preference decisions: Task-context of past experience matters

    Directory of Open Access Journals (Sweden)

    Hsin-I eLiao

    2011-03-01

    Full Text Available Our preferences are shaped by past experience in many ways, but a systematic understanding of the factors is yet to be achieved. For example, studies of the mere exposure effect show that experience with an item leads to increased liking (familiarity preference, but the exact opposite tendency is found in other studies utilizing dishabituation (novelty preference. Recently, it has been found that image category affects whether familiarity or novelty preference emerges from repeated stimulus exposure (Park, Shimojo, and Shimojo, PNAS 2010. Faces elicited familiarity preference, but natural scenes elicited novelty preference. In their task, preference judgments were made throughout all exposures, raising the question of whether the task-context during exposure was involved. We adapt their paradigm, testing if passive exposure or objective judgment task-contexts lead to different results. Results showed that after passive viewing, familiar faces were preferred, but no preference bias in either direction was found with natural scenes, or with geometric figures (control. After exposure during the objective judgment task, familiar faces were preferred, novel natural scenes were preferred, and no preference bias was found with geometric figures. The overall results replicate the segregation of preference biases across object categories and suggest that the preference for familiar faces and novel natural scenes are modulated by task-context memory at different processing levels or selection involvement. Possible underlying mechanisms of the two types of preferences are discussed.

    Objective To determine if there are differences or similarities in arthritis intervention preferences and barriers to participation between Blacks and Whites with osteoarthritis (OA). Methods Using a needs assessment survey, intervention preferences and barriers to participation in arthritis interventions among Black (n=60) and White (n=55) adults with self-reported doctor-diagnosed OA were examined. T-tests, chi-square tests, and multiple regression analyses adjusting for covariates were examined to determine race effects. Results While there were many similarities, Blacks were more likely to report cost (parthritis intervention. After adjusting for covariates, Blacks preferred interventions that provide information on arthritis-related internet sources (p=.04), solving arthritis-related problems (p=.04), and talking to family and friends about their condition (p=.02) in comparison to Whites. Blacks also preferred an intervention with child care services provided (parthritis interventions to minimize barriers, increase cultural sensitivity, and offer programs that would be appealing to Blacks and Whites with arthritis.

However, in case of bleeding there is no specific antidote to reverse their effects. We evaluated the preferences and values of anticoagulants of patients at risk of atrial fibrillation and those who have already made a decision regarding anticoagulation.Methods: We conducted a cross-sectional study of Veterans in the primary care clinics and the international normalized ratio (INR laboratory. We developed an instrument with patient and physician input to measure patient values and preferences. The survey contained a hypothetical scenario of the risk of atrial fibrillation and the attributes of each anticoagulant. After the scenario, we asked participants to choose the option that best fits their preferences. The options were: 1 has better efficacy at reducing risk of stroke; 2 has been in the market for a long period of time; 3 has an antidote to reverse the rare case of bleeding; 4 has better quality of life profile with no required frequent laboratory tests; or 5 I want to follow physician recommendations. We stratified our results by those patients who are currently exposed to anticoagulants and those who are not exposed but are at risk of atrial fibrillation.Results: We approached 173 Veterans and completed 137 surveys (79% response rate. Ninety subjects were not exposed to anticoagulants, 46 reported being on warfarin, and one reported being on dabigatran at the time of the survey. Ninety-eight percent of subjects stated they would like to participate in the decision-making process of selecting an anticoagulant. Thirty-six percent of those exposed and 37% of those

    Pain can be influenced by its social context. We aimed to examine under controlled experimental conditions how empathy from a partner and personal attachment style affect pain report, tolerance, and facial expressions of pain. Fifty-four participants, divided into secure, anxious, and avoidant attachment style groups, underwent a cold pressor task with their partners present. We manipulated how much empathy the participants perceived that their partners had for them. We observed a significant main effect of perceived empathy on pain report, with greater pain reported in the high perceived empathy condition. No such effects were found for pain tolerance or facial display. We also found a significant interaction of empathy with attachment style group, with the avoidant group reporting and displaying less pain than the secure and the anxious groups in the high perceived empathy condition. No such findings were observed in the low empathy condition. These results suggest that empathy from one's partner may influence pain report beyond behavioral reactions. In addition, the amount of pain report and expression that people show in high empathy conditions depends on their attachment style. Perspective Believing that one's partner feels high empathy for one's pain may lead individuals to rate the intensity of pain as higher. Individual differences in attachment style moderate this empathy effect. PMID:24953886

    2012-01-01

    Betrayal trauma theory suggests that social and cognitive development may be affected by early trauma such that individuals develop survival strategies, particularly dissociation and lack of betrayal awareness, that may place them at risk for further victimization. Several experiences of victimization in the context of relationships predicated on trust and dependence may contribute to the development of relational schema whereby abuse is perceived as normal. The current exploratory study investigates interpersonal trauma as an early experience that might impact the traits that are desired in potential romantic partners. Participants in the current study were asked to rate the desirability of several characteristics in potential romantic partners. Although loyalty was desirable to most participants regardless of their trauma history, those who reported experiences of high betrayal trauma rated loyalty less desirable than those who reported experiences of traumas that were low and medium in betrayal. Participants who reported experiences of revictimization (defined as the experience of trauma perpetrated by a close other during 2 different developmental periods) differed from participants who only reported 1 experience of high betrayal trauma in their self-reported desire for a romantic partner who possessed the traits of sincerity and trustworthiness. Preference for a partner who uses the tactic of verbal aggression was also associated with revictimization status. These preliminary findings suggest that victimization perpetrated by close others may affect partner preferences.

    Color preference is an important aspect of human behavior, but little is known about why people like some colors more than others. Recent results from the Berkeley Color Project (BCP) provide detailed measurements of preferences among 32 chromatic colors as well as other relevant aspects of color perception. We describe the fit of several color preference models, including ones based on cone outputs, color-emotion associations, and Palmer and Schloss's ecological valence theory. The ecological valence theory postulates that color serves an adaptive "steering' function, analogous to taste preferences, biasing organisms to approach advantageous objects and avoid disadvantageous ones. It predicts that people will tend to like colors to the extent that they like the objects that are characteristically that color, averaged over all such objects. The ecological valence theory predicts 80% of the variance in average color preference ratings from the Weighted Affective Valence Estimates (WAVEs) of correspondingly colored objects, much more variance than any of the other models. We also describe how hue preferences for single colors differ as a function of gender, expertise, culture, social institutions, and perceptual experience.

    Full Text Available Ecosystem service assessments have increasingly been used to support environmental management policies, mainly based on biophysical and economic indicators. However, few studies have coped with the social-cultural dimension of ecosystem services, despite being considered a research priority. We examined how ecosystem service bundles and trade-offs emerge from diverging social preferences toward ecosystem services delivered by various types of ecosystems in Spain. We conducted 3,379 direct face-to-face questionnaires in eight different case study sites from 2007 to 2011. Overall, 90.5% of the sampled population recognized the ecosystem's capacity to deliver services. Formal studies, environmental behavior, and gender variables influenced the probability of people recognizing the ecosystem's capacity to provide services. The ecosystem services most frequently perceived by people were regulating services; of those, air purification held the greatest importance. However, statistical analysis showed that socio-cultural factors and the conservation management strategy of ecosystems (i.e., National Park, Natural Park, or a non-protected area have an effect on social preferences toward ecosystem services. Ecosystem service trade-offs and bundles were identified by analyzing social preferences through multivariate analysis (redundancy analysis and hierarchical cluster analysis. We found a clear trade-off among provisioning services (and recreational hunting versus regulating services and almost all cultural services. We identified three ecosystem service bundles associated with the conservation management strategy and the rural-urban gradient. We conclude that socio-cultural preferences toward ecosystem services can serve as a tool to identify relevant services for people, the factors underlying these social preferences, and emerging ecosystem service bundles and trade-offs.

    Research on user behavior and preferences has been a helpful tool in improving road safety and accident prevention in recent years. At the same time, there remain some important areas of road safety and accident prevention for which user preferences, despite their importance, have not been explored. Most road safety research has not explicitly addressed vulnerable user (pedestrians and cyclists) preferences with respect to roundabouts, despite their increasing construction around the world. The present research stems from the fact that studies related to roundabout safety have generally focused on drivers, while overlooking the importance of safety as it relates to vulnerable users, especially pedestrians. Moreover, it handles this particular issue through an approach that has not been used so far in this context; the Stated Preference (SP) survey. As such, there are two main goals (and contributions) of this work. First, to show how SP surveys can be used to investigate the importance of different design and operational features to pedestrian perceptions of safety in roundabouts. This allows us, for example, to quantify how some features of roundabouts (e.g. high traffic volume) can be compensated for by design features such as pedestrian islands. This is useful in helping to design roundabouts that pedestrians prefer and will hopefully use, to help encourage active transport. Second, to demonstrate how traffic simulation software can be successfully used to include difficult-to-communicate attributes in SP surveys.

A self-administered anonymous questionnaire was designed to gather information on the preferred assessment method for course achievement. The preferred methods were also evaluated in relation to cognitive functions. Preference for specific exam format, in the form of multiple choices, short essay questions, or both, and the stated reasons for that preference, was also included in the questionnaire.Results: Out of 310 questionnaires distributed, 238 were returned. Written tests, projects, portfolios, and take home exams were the preferred modes for assessing students’achievements in a course; oral tests including a viva voce were the least preferred type of assessment. Questions that tested the domains of ‘understanding’ and ‘application’ were the most preferred type while those entailing ‘analysis’ were the least preferred. Multiple choice question format was the most preferred type of question (68.7% at both pre- and clinical stages.Conclusion: Students’ assessments at the College of Medicine, King Faisal University, Saudi Arabia, do not use the full range of cognitive domains. The emphasis on higher domains for medical students’ assessment incorporating critical thinking should increase as the students’ progress through their medical courses.Keywords: medical students, assessment, exams, multiple choices, essay

    Circulating PTH concentrations increase with age. It is uncertain whether an age-related PTH increase occurs independent of changes in circulating 25-hydroxyvitamin D, phosphate, renal function, and ionized calcium. The purpose of this article was to analyze the relationship between PTH and age, controlling for 25-hydroxyvitamin D, phosphate, renal function, and ionized calcium. This was a retrospective, cross-sectional study analyzing the relationship between PTH and age in 2 independent datasets (laboratory 1, n = 17 275 and laboratory 2, n = 4878). We further analyzed subgroups after excluding participants with estimated glomerular filtration rate of increase in age was associated with a 5.0% increase in PTH (95% confidence interval [CI], 4.4%-5.6%; P increase in laboratory 2 (95% CI, 3.0%-5.4%; P increase in age was associated with a 6.1% increase in PTH (95% CI, 5.5%-6.8%; P increase (95% CI 3.5%-6.2%; P increase with age, independent of 25-hydroxyvitamin D, ionized calcium, phosphate, and renal function. Further research is required to explore the underlying mechanisms and clinical relevance and to determine whether the use of age-related PTH reference ranges improves diagnostic accuracy, particularly in elderly individuals.

    Full Text Available Food availability for forest birds is a function of habitat type, forest management regime, and season. In winter, it is also impacted by variations in the weather. In the current study we assessed the food preferences of wild bird populations in two types of forest (spruce and beech during the months of November 2010 to April 2011 in the Schwäbische Alb Biodiversity Exploratory, south-western Germany. Our aim was to investigate whether local bird communities preferred fat-rich, carbohydrate-rich or wild fruits and to determine how forest structure, seasonality and local weather conditions affected food preferences. We found higher bird activity in beech forests for the eleven resident species. We observed a clear preference for fat-rich food for all birds in both forest types. Snow cover affected activity at food stations but did not affect food preferences. Periods of extreme low temperatures increased activity.

    Full Text Available Affective processing, known to influence attention, motivation and emotional regulation is poorly understood in young children, especially for those with neurodevelopmental disorders characterized by language impairments. Here we faithfully adapt a well-established animal paradigm used for affective processing, conditioned place preference for use in typically developing children between the ages of 30-55 months. Children displayed a conditioned place preference, with an average 2.4 fold increase in time spent in the preferred room. Importantly, associative learning as assessed with conditioned place preference was not correlated with scores on the Mullen Scales of Early Learning, indicating that conditioned place preference can be used with children with a wide range of cognitive skills.

  20. An Intra-Group Perspective on Leader Preferences

    2016-01-01

    This article argues that followers’ preferences for dominant leadership vary according to two types of exploitation risks from other individuals within the group. Previous work demonstrates that contexts of inter-group war and peace make followers prefer dominant- and non-dominant-looking leaders......, respectively. We add an intra-group perspective to this literature. Four original studies demonstrate that contexts with high risks of free-riding and criminal behavior from other group members (i.e., horizontal exploitation) increase preferences for dominant-looking leaders, whereas contexts with high risks...... of unresponsive, self-interested behavior from leaders themselves (i.e., vertical exploitation) decrease preferences for dominant-looking leaders. Moreover, within this framework of intra-group exploitation risks we show that followers prefer leaders from another vis-à-vis their own ethnic coalition to look less...

    Full Text Available Using path anaysis and the 5% PUMS data of the 1990 and 2000 censuses, this study examines 1 the correlation between Chinese-American sex preference for children and their fertility behavior, and 2 the interaction between the sex preference and its socioeconomic determinants. Of normative and non-normative factors investegated in this study, offspring sex preference is the greatest stimulus to Chinese fertility. Of socioeconomic variables, women’s educational attainment plays a primary role in depressing the impact of son preference in addition to their increasing stay in the host society. However, these two factors do not work on their husbands in the same way, demonstrating men’s inflexible attitudes toward gender roles in the family and in society. Son preference exerts positive impact on American-Chinese fertility and prevent from further decline. Yet, the influence has been diminishing since 1990 as observed in this study.

    2014-08-01

    The radiology job market has been described as highly variable, and recent practice hiring surveys predict that the number of available jobs will remain flat. Radiologists may be working more hours and retiring later than desired, activities that influence overall job availability. A national survey was performed to determine the desired work rate and retirement preferences of practicing radiologists, and the responses are used to estimate current and potential future work output and future workforce needs. Practicing radiologists were surveyed regarding current and preferred work level and desired and expected retirement age. A model incorporating these preferences and stratified by age was developed using survey responses and American Medical Association full-time equivalent (FTE) estimates. Available FTE radiologists are estimated under four scenarios from 2016 to 2031 in 5-year intervals. The model predicts a total of 26,362 FTE radiologists available in 2011, which corresponds to previous estimates. Participants reported working more hours and expecting to retire later than desired, with younger radiologists and women reporting the greatest desired decrease in FTE hours worked. Under each scenario, there is an initial FTE availability in 2016 ranging from 21,156 to 24,537, which increases to between 27,753 and 31,435 FTE by 2031 depending on work rate and retirement patterns. Practicing radiologists report that they currently work more hours than desired and expect to retire later than they would prefer. If radiologists changed current personal work rate and expected retirement age to meet these preferences, there would be an immediate shortage of FTE radiologists continuing until at least 2020 assuming no other workforce needs changes.

    Introduction Understanding patient perceptions and preferences of hospital care is important to improve patients’ hospitalization experiences and satisfaction. The objective of this study was to investigate patient preferences and perceptions of hospital care, specifically differences between intensive care unit (ICU) and hospital floor admissions. Methods This was a cross-sectional survey of emergency department (ED) patients who were presented with a hypothetical scenario of a patient with mild traumatic brain injury (TBI). We surveyed their preferences and perceptions of hospital care related to this scenario. A closed-ended questionnaire provided quantitative data on patient preferences and perceptions of hospital care and an open-ended questionnaire evaluated factors that may not have been captured with the closed-ended questionnaire. Results Out of 302 study patients, the ability for family and friends to visit (83%), nurse availability (80%), and physician availability (79%) were the factors most commonly rated “very important,” while the cost of hospitalization (62%) and length of hospitalization (59%) were the factors least commonly rated “very important.” When asked to choose between the ICU and the floor if they were the patient in the scenario, 33 patients (10.9%) choose the ICU, 133 chose the floor (44.0%), and 136 (45.0%) had no preference. Conclusion Based on a hypothetical scenario of mild TBI, the majority of patients preferred admission to the floor or had no preference compared to admission to the ICU. Humanistic factors such as the availability of doctors and nurses and the ability to interact with family appear to have a greater priority than systematic factors of hospitalization, such as length and cost of hospitalization or length of time in the ED waiting for an in-patient bed.

    Individual preferences for residential location, neighbourhood character and travel options are not always met. The availability and cost of housing and several other factors often require compromise. The primary objectives of this study were to examine neighbourhood preferences, quantify unmet demand for more walkable environments and explore associations between the built environment, travel behaviour and health after controlling for neighbourhood preference. A web-based, visually oriented residential preference survey was conducted with 1,525 adults in the Greater Toronto Area and 1,223 adults in Metro Vancouver aged 25 and older (5.8% and 11.8% of total potential recruits, respectively). Participants were randomly selected from a pre-recruited panel across a range of objectively calculated walkability and income levels at the forward sortation area level. Depending on the neighbourhood design attribute, between 45% and 64% of residents in the cities of Toronto and Vancouver strongly preferred living in walkable settings, compared with between 6% and 15% who strongly preferred auto-oriented places. Of participants who perceived their current neighbourhood as very auto-oriented, between 11% and 20% of City of Toronto participants and 6% and 30% of City of Vancouver participants strongly preferred a very walkable neighbourhood. Residents of highly walkable neighbourhoods reported walking significantly more for utilitarian purposes, taking public transit more frequently and driving fewer kilometres. Strong preferences for walking and transit-supportive neighbourhoods exist in two of Canada's largest metropolitan regions, with considerable unmet demand observed for such environments. The findings provide evidence for policies that enable walkability and inform market analysis, planning and regulatory approaches that better align with the supply and demand of more walkable neighbourhood environments.

    Full Text Available The purpose of the present paper is to identify if the congruence of the consumers personality with the perceived brand per-sonality increases their brand preferences. To achieve this purpose, the paper was structured in two parts; the first part contains a general literature review of the consumer behaviour theory and its influence factors and a more specific one regarding the consumer’s and brand personality concepts. The second part describes the used research methodology for achieving the paper’s purpose. The results of the underlying exploratory research confirmed the hypothesis that an overlapping of the consumers’ personality and the brand personality they perceive is positively correlated with their brand preferences.

  10. LEARNING STYLE PREFERENCES AND BALANCED LEARNERS

    Institute of Scientific and Technical Information of China (English)

    Just as students have different personalities, so do they have various learning styles. Why Otherwise might two people,compatible in age, intelligence and expectations, exposed to the same amount of opportunity, react so differently?Although an individual's learning style is regarded as relatively fixed and not easily changed, it is possible to help learners explore their own preferences and to shape their learning approaches to meet the demands of the requirements of what they intend to achieve. Using Honey and Mumford's Questionnaire and the systemized theory behind the questionnaire for analysis, this paper presents two arguments: 1. Trainers can help learners identify their learning style preferences and increase their awareness about them.2. Learners can become more effective learners once they are aware of their learning styles and the strong points and weak points of the different styles. The results of the investigation support the two arguments.

    The population-based University of Washington Twin Registry (UWTR) was used to examine (1) genetic influences on chronobiology and (2) whether these genetic factors influence alcohol-use phenotypes. We used a reduced Horne-Östberg Morningness-Eveningness Questionnaire (rMEQ) to survey UWTR participants for diurnal preference. Frequency and quantity of alcohol use, as well as binge drinking (6+ drinks per occasion), were assessed on a 5-point Likert scale. Both diurnal preference and alcohol use were self-reported. Twin data were analyzed by using structural equation models. The sample consisted of 2,945 participants (mean age = 36.4 years), including 1,127 same-sex and opposite-sex twin pairs and 691 individual twins. The rMEQ range was 4-25, with a mean score of 15.3 (SD 4.0). Diurnal "morning types" comprised 30.7% (N = 903) of participants, while 17.4% (N = 513) were "evening types." Regarding alcohol use, 21.2% (N = 624) reported never drinking. Among drinkers, 35.7% (N = 829) reported ≥ 3 drinks per occasion and 48.1% (N = 1,116) reported at least one instance of binge drinking. Genetic influences accounted for 37% of the variance in diurnal preference, with the remaining 63% due to non-shared environmental influences. Genetic propensities toward diurnal eveningness were significantly associated with increased alcohol quantity (β = -0.17; SE = 0.05, p Genetic influences on diurnal preference confer elevated risk for problematic alcohol use, including increased quantity and binge drinking. Differences in circadian rhythm may be an important and understudied pathway of risk for genetic influences on alcohol use.

    Dialysis patients frequently report a change of taste that is reversible after renal transplantation, suggesting that uremic toxins may negatively influence taste. Currently, frequent nocturnal home hemodialysis (NHHD) is the most effective method of hemodialysis, and is associated with the lowest levels of uremic toxins. We studied preferences for various foods as an indicator of taste perception. We questioned whether food preference differs between NHHD patients and those on conventional hemodialysis. In this transverse, cross-sectional pilot study, we assessed food preference by means of a questionnaire for patients on NHHD (n=6; 8 hours of dialysis per night, for 5 or 6 nights a week) and 3 age-matched and sex-matched control groups: chronic home hemodialysis patients (HHD; n=9; 4 to 5 hours of dialysis per day, 3 days a week), chronic in-center hemodialysis patients (CHD; n=18; 4 to 5 hours of dialysis per day, 3 days a week), and healthy control subjects (HC; n=23). Mean scores for food preference did not differ between groups (P=.32). Similarly, the preference for product groups did not differ between groups. On an individual product level, we found only minor differences. The NHHD patients had a preference for savory snacks, as did the HC and CHD groups, whereas the HHD group had a preference for sweet snacks (P food preference. The change in taste reported by NHHD patients is not related to their particular food preferences. Copyright (c) 2010 National Kidney Foundation, Inc. Published by Elsevier Inc. All rights reserved.

    The introduction of PowerPoint presentation software has generated a paradigm shift in the delivery of lectures. PowerPoint has now almost entirely replaced chalkboard or whiteboard teaching at the undergraduate and graduate levels. This study investigated whether undergraduate biology students preferred to have lectures delivered by PowerPoint or written on the board as well as the reasons behind their preference. Two upper-division physiology courses were surveyed over a period of 7 yr. A total of 1,905 students (86.7%) indicated they preferred lectures delivered by "writing on the board" compared to 291 students (13.3%) who preferred PowerPoint. Common themes drawn from explanations reported by students in favor of writing on the board included: 1) more appropriate pace, 2) facilitation of note taking, and 3) greater alertness and attention. Common themes in favor of PowerPoint included 1) increased convenience, 2) focus on listening, and 3) more accurate and readable notes. Based on the students' very strong preference for writing on the board and the themes supporting that preference, we recommend that instructors incorporate elements of the writing on the board delivery style into whatever teaching modality is used. If instructors plan to use PowerPoint, the presentation should be paced, constructed, and delivered to provide the benefits of lectures written on the board. The advantages of writing on the board can be also incorporated into instruction intended to occur outside the classroom, such as animated narrated videos as part of the flipped classroom approach.

    Multimorbidity is associated with use of multiple medicines, increased risk of adverse events and treatment conflicts. This study aimed to examine how older patients with multimorbidity and clinicians balance the benefits and harms associated with a medication and in the presence of competing health outcomes. Interviews were conducted with 15 participants aged ≥65 years with 2 or more chronic conditions. Three clinical scenarios were presented to understand patient preference to take a medicine according to i) degree of benefit, ii) type of adverse event and impact on daily living and iii) influence of comorbid conditions as competing health outcomes. Semi-structured interviews were also conducted with participants (n=15) and clinicians (n=5) to understand patient preferences and treatment decisions, in the setting of multimorbidity. The median age of participants was 79 years, 55% had 5 or more conditions and 47% took 8 or more medicines daily. When the level of benefit of the medicine ranged from 14% to 70%, 80% of participants chose to take the medicine, but when adverse effects were present, this was reduced to 0–33% depending upon impact on daily activities. In the presence of competing health outcomes, 13%–26% of patients chose to take the medicine. Two-thirds of patients reported that their doctor respects and considers their preferences and discussed medication benefits and harms. Interviews with clinicians showed that their overall approach to treatment decision-making for older individuals with multimorbidity was based upon 2 main factors, the patients’ prognosis and their preferences. The degree of benefit gained was not the driver of patients’ preference to take a medicine; rather, this decision was influenced by type and severity of adverse effects. Inclusion of patient preferences in the setting of risks and benefits of medicines with consideration and prioritization of competing health outcomes may result in improved health outcomes for

    The aim of this study was to determine the role of community preference information from discrete choice studies of colorectal cancer (CRC) screening in health technology assessment (HTA) reports and subsequent policy decisions. We undertook a systematic review of discrete choice studies of CRC screening. Included studies were reviewed to assess the policy context of the research. For those studies that cited a recent or pending review of CRC screening, further searches were undertaken to determine the extent to which community preference information was incorporated into the HTA decision-making process. Eight discrete choice studies that evaluated preferences for CRC screening were identified. Four of these studies referred to a national or local review of CRC screening in three countries: Australia, Canada, and the Netherlands. Our review of subsequently released health policy documents showed that while consideration was given to community views on CRC, policy was not informed by discrete choice evidence. Preferences and values of patients are increasingly being considered "evidence" to be incorporated into HTA reports. Discrete choice methodology is a rigorous quantitative method for eliciting preferences and while as a methodology it is growing in profile, it would appear that the results of such research are not being systematically translated or integrated into HTA reports. A formalized approach is needed to incorporate preference literature into the HTA decision-making process.

  17. Choice in experiential learning: True preferences or experimental artifacts?

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

    2017-02-09

    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.

    Peaches (Prunus persica (L.) Stokes) are grown in several regions throughout the USA, are eaten fresh, and used as ingredients in value-added processed products. An Internet survey was conducted to investigate Mid-Atlantic consumers' fresh and processed peach purchasing behaviors, and whether packaging certain numbers of peaches together, providing information about nutritional content, and other factors would increase purchases. Additionally, laboratory-based sensory testing was used to better understand peel color, texture, sweetness, sourness, and flavor preferences for cultivars commonly grown in the Mid-Atlantic region. Irrespective of fresh peach consumption frequency, certain value-added products were of interest. For some products, interest in purchasing was higher than reported purchasing behavior. Preference for certain fresh peach characteristics, such as peel color, differed between less frequent fresh peach consumers and those who consumed fresh peaches more often. Of the four peach cultivars included in the sensory test, most were liked; however, there were some cultivar differences pertaining to color, texture, sweetness, tartness, and flavor liking. Potential marketing strategies can be developed based on frequency of fresh peach consumption and household demographics. Data can be used to select peaches that best appeal to consumers. © 2015 Society of Chemical Industry. © 2015 Society of Chemical Industry.

    To describe the dietary intake patterns of women before and after breast cancer diagnosis. 3,084 women (age range 27 to 70 years) who had been treated for early-stage breast cancer, who were free of recurrent disease, and who were willing to complete study questionnaires. A descriptive analysis of baseline demographic and lifestyle questionnaire data, including reported dietary intake data from women who have had breast cancer participating in a randomized, controlled dietary intervention trial. Outcomes include dietary intakes of high- and low-fat foods, fruits and vegetables, and whole grains. Analyses included frequency of intake of selected food items, chi2 analysis to determine associations between reported intakes and demographic and personal characteristics, and logistic regression to assess odds of making more healthful changes. Women who have had breast cancer reported higher fruit, vegetable, and fiber-rich food intakes (58%, 60%, 38% more, respectively) and lower intakes of high-fat foods, including fast foods, after diagnosis. Those older than age 60 years were more likely to report no change in intake, including red meat (41%), vegetables (51%), and whole grains (62%). Odds ratios (OR) for more healthful diet choices varied by age and time since diagnosis.

    2010-01-01

    Studies that have assessed whether children prefer contingent reinforcement (CR) or noncontingent reinforcement (NCR) have shown that they prefer CR. Preference for CR has, however, been evaluated only under continuous reinforcement (CRF) schedules. The prevalence of intermittent reinforcement (INT) warrants an evaluation of whether preference for CR persists as the schedule of reinforcement is thinned. In the current study, we evaluated 2 children's preference for contingent versus noncontingent delivery of highly preferred edible items for academic task completion under CRF and INT schedules. Children (a) preferred CR to NCR under the CRF schedule, (b) continued to prefer CR as the schedule of reinforcement became intermittent, and (c) exhibited a shift in preference from CR to NCR as the schedule became increasingly thin. These findings extend the generality of and provide one set of limits to the preference for CR. Applied implications, variables controlling preferences, and future research are discussed.

Although glucagon-like peptide-1 (GLP-1 analog and dipeptidyl peptidase-4 (DPP-4 inhibitor medications are effective, there are differences between these products, including method of administration (injectable versus oral. The objective of this study was to examine patient preferences (and predictors of preferences for two different medication profiles, one similar to a GLP-1 analog (liraglutide and another similar to a DPP-4 inhibitor (sitagliptin.Methods: Internet survey data were collected in two waves (wave 1, n = 2402; wave 2, n = 1340 using patients from the US and Europe. Patients were presented with two hypothetical medication profiles (“drug A” and “drug B”, resembling sitagliptin and liraglutide, respectively and asked to report their preferences.Results: Most patients in wave 1 and wave 2 reported that overall they would prefer a drug with the sitagliptin-like profile (81.9% and 84.4%, respectively over a drug with the liraglutide-like profile (18.1% and 15.6%, respectively, and >80% of patients reported that they would be able to take a drug with the sitagliptin-like profile as directed by their physician for a longer period. The likelihood of preferring the sitagliptin-like profile significantly increased as age (odds ratio [OR] = 1.02 and importance placed on method of administration (OR = 1.32 increased (P < 0.05. Although the sitagliptin-like profile was preferred by the majority of patients in all subgroups, a lower proportion of patients with obesity, with weight gain, with A1C values above target, and who exercised preferred the sitagliptin-like profile compared with

    Full Text Available The paper attempts to explore how women and men differ in their individual investment preferences. Although there are some studies for the investors in developed countries, the subject has been overlooked in emerging and underdeveloped countries. Therefore, this study is the first empirical study exploring the investment behaviors of women and men by focusing on an emerging country, Turkey. For the purpose to find out how investment preferences of men and women differ towards six investment tools, namely, gold, foreign currency, funds, common stocks, real estates, and time deposits, a discriminant analysis and a logistic regression were exercised. The results revealed that while men investors prefer common stocks and real estate to invest women investors are more risk averse and invest fund, time deposit and gold. There is no significant difference between men and women in foreign currency investment.

    2008-01-01

    Given an argumentation framework AF, we introduce a mapping function that constructs a disjunctive logic program P, such that the preferred extensions of AF correspond to the stable models of P, after intersecting each stable model with the relevant atoms. The given mapping function is of polynomial size w.r.t. AF. In particular, we identify that there is a direct relationship between the minimal models of a propositional formula and the preferred extensions of an argumentation framework by working on representing the defeated arguments. Then we show how to infer the preferred extensions of an argumentation framework by using UNSAT algorithms and disjunctive stable model solvers. The relevance of this result is that we define a direct relationship between one of the most satisfactory argumentation semantics and one of the most successful approach of non-monotonic reasoning i.e., logic programming with the stable model semantics.

    Full Text Available Salt intake has been implicated in the pathogenesis of abdominal aortic aneurysm (AAA through studies in rodent models but not previously studied in humans. The aim of this study was to examine the association between reported addition of salt to food and the prevalence of AAA.A risk factor questionnaire which contained a question about salt intake was included as part of a population screening study for AAA in 11742 older men. AAA presence was assessed by abdominal ultrasound imaging using a reproducible protocol.The prevalence of AAA was 6.9, 8.5 and 8.6% in men who reported adding salt to food never, sometimes and always, respectively, p = 0.005. Addition of salt to food sometimes (odds ratio [OR]: 1.22, 95% confidence interval [CI]: 1.03-1.44 or always (OR: 1.23, 95% CI 1.04-1.47 was independently associated with AAA after adjustment for other risk factors including age, waist-hip ratio, blood pressure, history of hypertension, high cholesterol, angina, diabetes, myocardial infarction and stroke. Salt intake was also independently associated with aortic diameter (beta 0.023, p = 0.012. In men with no prior history of hypertension, high cholesterol, angina, myocardial infarction or stroke (n = 4185, the association between addition of salt to food sometimes (OR: 1.41, 95% CI 0.96-2.08 or always (OR: 1.52, 95% CI 1.04-2.22 and AAA remained evident.Reported salt intake is associated with AAA in older men. Additional studies are needed to determine whether reducing salt intake would protect against AAA.

    Full Text Available Introduction: Patient preferences are important for medication adherence and patient satisfaction, but little is known about older adult preferences for inhaler devices. Methods: We developed a 25-item written self-administered questionnaire assessing experience with inhalers, prior inhaler education, and preferences with respect to inhaler device features and inhaler device teaching. We then conducted a cross-sectional survey of patients at least 65 years of age with chronic lung disease who had experience using inhaler devices for at least six months in the ambulatory setting. Results: Fifty participants completed the questionnaire. The majority of participants (80% reported prior experience with a metered dose inhaler (MDI, but only 26% used an MDI with a spacer. Most patients (76% had received formal instruction regarding proper use of the inhaler, but only 34% had ever been asked to demonstrate their inhaler technique. Physician recommendation for an inhaler, cost of the inhaler device, and inhaler features related to convenience were important with respect to patient preferences. With regard to inhaler education, participants prefer verbal instruction and/or hands-on demonstration at the time a new inhaler is prescribed in the setting of the prescribing provider’s office. Conclusion: Patient preferences for inhaler devices and inhaler education among older adults indicate physician recommendation, cost, and convenience are important. The impact of patient preferences on inhaler adherence and clinical outcomes remains unknown.

    Customer preference (CP), or green pricing, may be the financial hedge for electric supply industry integration of photovoltaics. CP is currently defined as a voluntary contribution for energy generated with renewable resources. Several utilities have examined the CP financing of renewables through experimental or implemented programs and market research. This paper first expands the concept of customer preference to include both voluntary and involuntary customer contributions. It then categorizes the features of existing and proposed CP programs. The connections between these features and market research and marketing strategies for new product development from a competitive industry are analyzed.

    Numbers permeate modern political communication. While current scholarship on framing effects has focused on the persuasive effects of words and arguments, this article shows that framing of numbers can also substantially affect policy preferences. Such effects are caused by ratio bias, which...... is a general tendency to focus on numerators and pay insufficient attention to denominators in ratios. Using a population-based survey experiment, I demonstrate how differently framed but logically equivalent representations of the exact same numerical value can have large effects on citizens’ preferences...

    2012-06-01

    We study experimentally the relationship between distributional preferences and competitive behavior. We find that spiteful subjects react strongest to competitive pressure and win in a tournament significantly more often than efficiency-minded and inequality averse subjects. However, when given the choice between a tournament and a piece rate scheme, efficiency-minded subjects choose the tournament most often, while spiteful and inequality averse subjects avoid it. When controlling for distributional preferences, risk attitudes and past performance, the gender gap in the willingness to compete is no longer significant, indicating that gender-related variables explain why twice as many men as women self-select into competition.

    Full Text Available Abstract Introduction Mediastinal mature teratoma is a benign, slow-growing tumor typically affecting 20- to 40-year-old adults. Fluid examination from the cystic masses rarely shows enzymatic activity as we describe in this report. Case presentation We report a case of a giant mediastinal germ cell tumor (measuring 15 cm × 14 cm × 8 cm detected in a 35-year-old Caucasian woman. Microscopic examination showed that the lesion resembled a mature cystic teratoma with areas of pancreatic tissue with mature ductal and acinar structures intermixed with islets of Langerhans. Fluid from the cysts in the mass was examined after removal showed amylase activity of 599 U/l despite normal serum levels. The post-operative period was free of complications, and the patient was discharged on post-operative day 10. Conclusion Complete surgical removal is the treatment of choice for mature cystic teratomas, with optimal results and acceptable surgical risk. Exocrine pancreatic function may be an aid to pre-operative or intra-operative diagnosis; however, these findings have no impact on survival or the therapeutic pathway.

    Fat is an important source of both pleasure and calories in the diet. Dairy products are a major source of fat in the diet, and understanding preferences for fat in fluid milk can potentially inform efforts to change fat consumption patterns or optimize consumer products. Here, patterns of preference for fat in milk were determined in the laboratory among 100 free living adults using rejection thresholds. Participants also answered questions relating to their health concerns, the type of fluid milk typically consumed, and their declared preference for type of milk (in terms of fat level). When revealed preferences in blind tasting were stratified by these measures, we observed striking differences in the preferred level of fat in milk. These data indicate a non-trivial number of consumers who prefer low-fat milk to full fat milk, a pattern that would have been overshadowed by the use of a group mean. While it is widely assumed and claimed that increasing fat content in fluid milk universally increases palatability, present data demonstrate this is not true for a segment of the population. These results underscore the need to go look beyond group means to understand individual differences in food preference.

    ♦ This study was carried out to examine whether or not elderly patients on peritoneal dialysis (PD) had an increased risk of peritonitis. ♦ This was a retrospective cohort study based on data from the French Language Peritoneal Dialysis Registry. We analyzed 8,396 incident patients starting PD between January 2003 and December 2010. The end of the observation period was 31 December 2012. Patients were separated into 2 age groups: up to 75 and over of 75 years old. ♦ Among 8,396 patients starting dialysis there were 3,173 patients older than 75. When using a Cox model, no association was found between age greater than 75 years and increased risk of peritonitis (hazard ratio [HR]: 0.97 [0.88 - 1.07]). Diabetes (HR: 1.14 [1.01 - 1.28] and continuous ambulatory PD (HR: 1.13 [1.04 - 1.23]) were significantly associated with a higher risk of peritoneal infection whereas nurse-assisted PD was associated with a lower risk of peritonitis (HR: 0.85 [0.78 - 0.94]. In the analysis restricted to the 3,840 self-care PD patients, there was no association between age older than 75 years and risk of peritonitis. ♦ The risk of peritonitis is not increased in elderly patients on PD in a country where assisted PD is available.

    Genetic testing for susceptibility to major depressive disorder (MDD) is not available for clinical use at present. Given this, family history remains the best predictor for development of MDD, and family-history-based risk assessment and information about familial aspects of MDD may be useful to clients at increased risk for MDD attending for genetic counseling. This study uses a mixed-methods design to assess the information needs and preferences of people at increased familial risk for MDD. Telephone interviews were conducted with 23 individuals, who had at least one first-degree relative with MDD and were recruited through advertisements placed on depression education websites. The most preferred way to access depression information was via the internet (87 % of participants), although this preference may have been due to the internet-based recruitment method. The second most preferred dissemination strategy (56 %) was face-to-face delivery through a health professional, including genetic counselors. Individuals reported a need for information about etiology and development of MDD, reproductive decision-making, early detection of symptoms and risk-reducing strategies. Nearly all participants expressed an interest in risk assessment. The present study found evidence of a high level of interest for information targeted to people at increased familial risk for MDD. Genetic counselors are likely to be called upon increasingly to provide supportive counseling to assist clients at increased familial risk in interpreting and contextualizing such information once it becomes available.

    (1) To identify physicians' preferences in regard to pharmacist-provided medication therapy management (MTM) communication in the community pharmacy setting; (2) to identify physicians' perceived barriers to communicating with a pharmacist regarding MTM; and (3) to determine whether Missouri physicians feel MTM is beneficial for their patients. A cross-sectional prospective survey study of 2021 family and general practice physicians registered with MO HealthNet, Missouri's Medicaid program. The majority (52.8%) of physicians preferred MTM data to be communicated via fax. Most physicians who provided care to patients in long-term care (LTC) facilities (81.0%) preferred to be contacted at their practice location as opposed to the LTC facility. The greatest barriers to communication were lack of time and inefficient communication practices. Improved/enhanced communication was the most common suggestion for improvement in the MTM process. Approximately 67% of respondents reported MTM as beneficial or somewhat beneficial for their patients. Survey respondents saw value in the MTM services offered by pharmacists. However, pharmacists should use the identified preferences and barriers to improve their currently utilized communication practices in hopes of increasing acceptance of recommendations. Ultimately, this may assist MTM providers in working collaboratively with patients' physicians.

    To investigate general practitioners' (GPs) preferences for involvement in the management of people diagnosed with the seven most frequent cancers and any barriers to or concerns about an expanded role for GPs. A self-report survey was mailed to a random sample of 1969 Australian GPs. In all, 33% (648) of GPs participated. Participants were a median of 50 years and worked 38 h per week; 53% were male and 68% practiced in metropolitan areas. Most participants preferred to be involved in cancer prevention (86%) and initial diagnosis (85%). Fewer were interested in monitoring for recurrence (70%), follow up after treatment (68%), coordinating psychological support (70%) and palliative care (68%). Only 52% of GPs had a preference for providing supportive care to manage the symptoms of cancer treatment, 45% for managing postoperative care and 40% for coordinating treatment. On multivariate analysis, preference for involvement in more aspects of cancer management increased with age (P = 0.030), if the GP practiced in rural compared to metropolitan areas (P = 0.005), was a partner in a practice compared to a sole practitioner (P = 0.003), had previously received cancer-specific training (P management. While many GPs are currently involved in some aspects of cancer management, with training, good communication and support from specialists this role may be successfully expanded. © 2012 Wiley Publishing Asia Pty Ltd.

    Tailored feedback on personal physical activity behavior has been used to inform individuals and promote physical activity among different populations. This study aimed to increase the understanding of factors associated with young men's preferences for feedback message tactics in the context of physical activity and exercise. How preferences vary was analyzed in terms of the self-reported physical activity, stage of exercise behavior change, exercise self-efficacy, objectively measured physical health status, and sociodemographic characteristics of young Finnish men. Population-based survey data, including physiological measurements (n = 525), were collected at the Finnish Defence Forces' call-ups in the city of Oulu, Finland, in September 2011. The results indicate that the stage of exercise behavior change, exercise self-efficacy, physical health status, and educational level are associated with a preference for normative and ipsative comparison. Multivariate logistic regression models show that an advanced stage of exercise behavior change and education in the academic track of an upper secondary school are independent predictors of preferring ipsative and normative physical activity feedback among young men. The study provides new insights into how the stage of behavior change influences health information behavior and is in line with studies emphasizing social factors--including education--as being important in shaping health-related behavior. These factors could form the basis for tailoring information when designing health promotion.

    Full Text Available Smallholder sugarcane production sector is under researched and underdeveloped with limited industrial link and support. The objectives of this study were to assess the current state of sugarcane production, farmers’ perceived production constraints and preferred traits, and to collect germplasm grown by smallholder farmers in southern Ethiopia for strategic breeding and conservation. The study was conducted across 16 administrative zones, 28 districts and 56 peasant associations involving 560 smallholder sugarcane growers in southern Ethiopia using a participatory rural appraisal (PRA approach. Sugarcane genetic resources were collected through structured sampling. Findings from this study indicated that monocropping was identified as the predominant sugarcane farming system. Respondent farmers prioritized drought tolerance (21%, increased cane yield (20%, early maturity (18%, marketability (17%, and high biomass (14% as the top preferred traits of sugarcane. Ninety diverse sugarcane landraces were collected from homesteads of smallholder farmers. Findings from this study would serve as baseline information towards sugarcane research and development emphasising the constraints and preferences of smallholder sugarcane growers in Ethiopia or similar agro-ecologies. This is the first study to report farmers preferred traits and constraints, and genetic resources of sugarcane under smallholder farming systems in Ethiopia.

    The objective of this study is to report on an in-depth evaluation of patient experiences and preferences at a Head and Neck Oncology outpatient clinic. A qualitative research design was used to determine the experiences and preferences of Head and Neck Cancer patients in an Oncology Outpatient Clinic, Maastricht University Medical Center, The Netherlands. Head and Neck Cancer Patients, treated for at least 6 months at the Oncology Clinic, were included. A qualitative research design with patient interviews was used. All interviews were recorded and transcribed verbatim to increase validity. Analysis was done with use of the template approach and qualitative data analysis software. Three of the six dimensions predominated in the interview: (1) respect for patients' values, preferences and expressed need, (2) information, communication and education and (3) involvement of family and friends. The dimensions physical comfort; emotional support; coordination and integration of care were considered to be of less significance. The findings from this study resulted in a deeper understanding of patients' experiences and preferences and can be useful in the transition towards a more patient-centered approach of health care.

    Access to electrification in rural areas of East Timor is extremely limited with as few as 5% of rural households connected to electricity. The government of East Timor intends to increase rural access to electricity significantly in the coming decade. The introduction of small PV systems is envisaged for many households in the most remote areas. Several agencies have piloted the introduction of small solar home systems (SHS) and solar lanterns. In the Railaco sub-district of East Timor, some 1000 households have experience of using either SHS and/or solar lanterns and are in a unique position to indicate a preference regarding these forms of PV lighting technology. This paper reports on a survey of 76 households in Railaco investigating experience with PV lighting systems. Results of the survey indicate a strong preference by users for SHS rather than lanterns. The preference for SHS arose from a range of factors including: a perception of better light quality; ability to illuminate the whole house; reduced risk of damage to the PV equipment; and longer duration of nightly operation. The research indicates that where a single PV lighting system is provided, users are likely to prefer SHS to solar lanterns. (author)

    This study investigated preferences for behavioural, analytic and gestalt psychotherapy among a sample of 40 SES class III and IV adult females and 67 college freshmen who had never been actual therapy patients. A scaled survey assessed general preference, preference given an imagined long-standing depressive disorder, preference given an imagined specific phobia, and preference for the therapist-patient relationship. Three audio tapes were designed, each describing one of the modalities. High inter-rater reliability and agreement were determined by three independent judges. Results showed that young females had a general preference for gestalt therapy. Young and old females, but not young males, significantly preferred behavioural therapy for a specific phobia. Under forced-choice conditions the group as a whole significantly preferred gestalt therapy. No differences were found for the relationship or preference given a depressive disorder. Preference was hypothesized as a cognitive structure with potential use in therapist-client matching.

The primary aims of this multicenter study were to evaluate patient experience and satisfaction with CTC screening and compare preference against screening colonoscopy. MATERIALS AND METHODS A 12-question survey instrument measuring pretest choice, experience, and satisfaction was given to a consecutive cohort of adults undergoing CTC screening in three disparate screening settings: university academic center, military medical center, and community practice. The study cohort was composed of individuals voluntarily participating in clinical CTC screening programs. RESULTS A total of 1417 patients responded to the survey. The top reasons for choosing CTC for screening included “noninvasiveness” (68.0%), “avoidance of sedation/anesthesia” (63.1%), “ability to drive after the test” (49.2%), “avoidance of optical colonoscopy risks” (46.9%), and “identifying abnormalities outside the colon” (43.3%). Only 7.2% of patients reported pain during the CTC examination and only 2.5% reported greater than moderate discomfort. Of 441 patients who had experienced both CTC and optical colonoscopy, 77.1% preferred CTC and 13.8% preferred optical colonoscopy. Of all patients, 29.6% indicated that they may not have undergone optical colonoscopy screening if CTC were not available. Of all patients, 92.9% labeled their overall experience with CTC as “excellent” or “good,” and 93.0% indicated they would choose CTC for their next screening. CONCLUSION Respondents reported a very high satisfaction level with CTC, and those who had experienced both modalities indicated a preference for CTC over optical colonoscopy. These results suggest that CTC has the potential to increase adherence to CRC screening guidelines if widely available. PMID:22623549

    Several recent studies have investigated the choice between heroin and a non-drug alternative reinforcer in rats. A common finding in these studies is that there are large individual differences in preference, with some rats preferring heroin and some preferring the non-drug alternative. The primary goal of the present study was to determine whether individual differences in how heroin or saccharin is valued, based on demand analysis, predicts choice. Rats lever-pressed for heroin infusions and saccharin reinforcers on fixed-ratio schedules. The essential value of each reinforcer was obtained from resulting demand curves. Rats were then trained on a mutually exclusive choice procedure where pressing one lever resulted in heroin and pressing another resulted in saccharin. After seven sessions of increased access to heroin or saccharin, rats were reexposed to the demand and choice procedures. Demand for heroin was more elastic than demand for saccharin (i.e., heroin had lower essential value than saccharin). When allowed to choose, most rats preferred saccharin. The essential value of heroin, but not saccharin, predicted preference. The essential value of both heroin and saccharin increased following a week of increased access to heroin, but similar saccharin exposure had no effect on essential value. Preference was unchanged after increased access to either reinforcer. Heroin-preferring rats differed from saccharin-preferring rats in how they valued heroin, but not saccharin. To the extent that choice models addiction-related behavior, these results suggest that overvaluation of opioids specifically, rather than undervaluation of non-drug alternatives, could identify susceptible individuals.

    2009-11-01

    We administered a 65-item survey to patients to assess preference of symptoms and peak flow to detect worsening asthma and to collect information about asthma triggers, asthma knowledge sources, and barriers to peak flow meter use. It was completed by 139 asthma patients. Survey responses were comparable for adult and pediatric patients and for those who owned peak flow meters and those who did not. But patients who owned a peak flow meter reported more severe asthma than others. On average, the patients preferred symptoms to peak flow for assessing worsening asthma. It is likely that the preference for symptom over peak flow monitoring was effort related: Patients preferred symptom monitoring because it was the easier of the two to conduct.

    Coca-Cola (Coke) and Pepsi are nearly identical in chemical composition, yet humans routinely display strong subjective preferences for one or the other. This simple observation raises the important question of how cultural messages combine with content to shape our perceptions; even to the point of modifying behavioral preferences for a primary reward like a sugared drink. We delivered Coke and Pepsi to human subjects in behavioral taste tests and also in passive experiments carried out during functional magnetic resonance imaging (fMRI). Two conditions were examined: (1) anonymous delivery of Coke and Pepsi and (2) brand-cued delivery of Coke and Pepsi. For the anonymous task, we report a consistent neural response in the ventromedial prefrontal cortex that correlated with subjects' behavioral preferences for these beverages. In the brand-cued experiment, brand knowledge for one of the drinks had a dramatic influence on expressed behavioral preferences and on the measured brain responses.

  17. Pregnant women’s preference for vaginal or caesarean childbirth

    2009-10-01

    Full Text Available The study investigated the preference for delivery in 40 pregnant women using a semi-structured interview. Most women (75% reported a preference for vaginal delivery, mainly because they believe it will result in a speedy recovery and be better for them and/or their babies. Of the women interviewed, 15% preferred a caesarean section because they considered it be less painful. These preferences, in general, were influenced by friends. Most women said they had fear of parturition due to: feelings of pain/suffering, concern of something happening to them or their babies and because the situation is unknown or assessed in a negative fashion. The presence of trusted people, like one’s husband, mother or doctor, could minimize this fear. These results reinforce the contributions of health professionals, such as psychologists, in answering the psychosocial needs of pregnant women in situations of delivery and birth.   Keywords: vaginal birth; caesarean section; pregnancy; health psychology.

  18. Increasing the Social Communication of a Boy With Autism Using Animal-assisted Play Therapy: A Case Report.

    2015-01-01

    Although research has shown that animal-assisted play therapy (AAPT) is associated with increased positive social behaviors in children with autism, the related literature on AAPT and autism is very limited. The study tested the effectiveness of AAPT in increasing the social communication of a boy with autism. The treatment's effects on specific types of social communication were also investigated. An A-B-A single-subject design was adopted to examine treatment effectiveness. Follow-up assessments were made at 1 mo posttreatment. The videotaped treatment sessions were held in the multipurpose room of the participant's school. A 7-y-old boy who had a diagnosis of autism and mild-grade intellectual disability participated in the study. AAPT was implemented in 20-min sessions held 3 ×/wk. The 14 AAPT sessions occurred in 4 phases, covering child-dog relationship building and interaction in the presence of the therapist, with the diminishing presence of the dog occurring in phase 4. Naturally occurring social behaviors were measured in 3 baseline sessions, during the 14 AAPT sessions, during 3 posttreatment sessions, and again during 3 follow-up sessions. Momentary time sampling was used to estimate the frequency of target behaviors, using a 15-s interval. Behavioral categories were checked at every interval during each 20-min session in all 23 sessions. The study showed that the boy's social communication increased during treatment and remained higher than baseline at follow-up. An analysis of specific types of social communication showed that the benefits of AAPT were most apparent in the joint-attention and waiting behaviors. The findings provide support for using AAPT as an intervention to facilitate the social communication of children with autism.

    2011-01-01

    The aim of this study was to perform a systematic review of papers that assess the effect of television food advertisings (TFA) in the food preferences and consumption in different age groups. Randomized clinical trials published up to November 2010 were searched in Pubmed, Ebsco, Cochrane and Scielo. Studies were included if they assessed the effect of direct exposition to TFA over the food preferences, demand, and consumption. Ten studies fulfilled the inclusion criteria. In the three studies conducted on preschooler children an increase in selection and demand of advertized foods was reported. All the fives studies conducted on scholar children reported negative outcomes in those children exposed to unhealthy food. An increase on food consumption was observed in two of the three studies conducted on adults. The assess studies show that in pre-school and school children the effect of advertising on food consumption was consistent, while in adults there is a trend toward an strong association of exposure food advertising and preference, consumption and demand of the food advertised.

A large body of research indicates, however, that preferences often are labile. That is, preferences can be reversed depending on factors such as how the preference is elicited. In three studies, we examine the effect of familiarity in two preference elicitation tasks, choice and matching judgments. We provide evidence of an interaction between fami...

    Danish full-scale biogas plants operate with manure as a primary substrate, of which cattle manure represents a significant fraction. Conversion of the lignocellulosic fibre fraction of manure was shown to be the rate-degrading step of the anaerobic digestion. The aim of this project was to investigate if the biological methods, such as bioaugmentation of the reactor with specific anaerobic, hydrolytic bacteria would improve hydrolysis of fibres and result in an increase of the methane yield of cattle manure. Results of this study showed, that there is a potential for an increase of the methane yield of manure by inoculating the fibre-containing substrate with cellulose- and alkaliphilic xylane-hydrolyzing bacterial cultures. The highest increase of methane yield in batch experiment was obtained at 37 deg. C and 68 deg. C, while the effect at 55 deg. C was poor. Direct inoculation of a mesophilic reactor with Clostridium cellulovorans (DSM 3052) was not successful. The fate of the organism, followed by 16S rRNA probing, proved that DSM 3052 was not a member of the indigenous microflora, and that the active population of DSM 3052 could not be established within the reactor. On the other hand, inoculation of a reactor with our own isolate, a new clostridial strain, Clostridium sp. SA 14, resulted in a significant increase of the methane yield from 220 ml CH{sub 4}/g VS up to 330 ml CH{sub 4}/g VS. However, during the continuous reactor operation in the period of one retention time, the effect was reduced and finally disappeared. Therefore, it would be necessary in the future to develop a new strategy for establishment of this strain within the reactor environment. Anaerobic digestion of manure was also studied in a two-step process, where manure was first hydrolyzed at 68 deg. C, and thereafter digested in a conventional methanogenic step at 55 deg. C. Investigation from batch experiment resulted in a 24%- increase in methane yield for the two-step digestion compared

    1981-12-10

    The impact of DOE's Current Federal Program on the commercialization of hydrothermal resources between 1980 and 2000 is analyzed. The hydrothermal resources of the United States and the types of DOE activities used to stimulate the development of these resources for both electric power and direct heat use are described briefly. The No Federal Program and the Current Federal Program are then described in terms of funding levels and the resultant market penetration estimates through 2000. These market penetration estimates are also compared to other geothermal utilization forecasts. The direct benefits of the Current Federal Program are next presented for electric power and direct heat use applications. An analysis of the external impacts associated with the additional hydrothermal resource development resulting from the Current Federal Program is also provided. Included are environmental effects, national security/balance-of-payments improvements, socioeconomic impacts and materials requirements. A summary of the analysis integrating the direct benefits, external impacts and DOE program costs concludes the report.

    Globozoospermia, characterised by the presence of round spermatozoa lacking acrosomes in an ejaculate, is a known cause of male infertility. Semen analysis, including sperm chromatin structure assay, toluidine blue, chromomycin A3 and aniline blue staining and fluorescence in situ hybridisation, was performed in an infertile globozoospermic patient to establish to which extent these genetic factors contributed to his infertility. No spermatozoa capable of hyaluronan (HA) binding were detected in the HA binding assay. Increased rates of immature spermatozoa with defective replacement of histones by protamines, DNA breaks and disturbed chromatin integrity and sperm aneuploid for the sex chromosomes were observed. Intracytoplasmic sperm injection (ICSI) was used in three in vitro fertilisation (IVF) cycles, and enough morphologically well-developing embryos were obtained in each cycle. However, no pregnancy was achieved. The infertility of our couple, resistant to IVF/ICSI treatment, was most probably caused by a combination of male and female factors.

    2013-04-01

    Full Text Available Increasing student engagement within higher education academic support services is a constant challenge. Whilst engagement with support is positively associated with successful retention, and non-engagement connected to attrition, the most vulnerable students are often the least likely to engage. Our data has shown that Health Science students are reluctant to engage with academic support services despite being made aware of their academic deficiencies. The “psychology of seeking support” was used as a lens to identify some of the multifaceted issues around student engagement. The School of Health Sciences made attendance at support courses compulsory for those students who were below the benchmark score in a post entrance literacy test. Since the policy change was implemented, there has been a 50% reduction in the fail rate of “at risk” students in a core literacy unit. These findings are encouraging and will help reduce student attrition in the long term.

    Screening persons living with HIV for gonorrhea and chlamydia has been recommended since 2003. We compared annual gonorrhea/chlamydia testing to syphilis and lipid testing among 19,368 adults (41% men who have sex with men, 30% heterosexual men, and 29% women) engaged in HIV care. In 2004, 22%, 62%, and 70% of all patients were tested for gonorrhea/chlamydia, syphilis, and lipid levels, respectively. Despite increasing steadily [odds ratio per year (95% confidence interval): 1.14 (1.13 to 1.15)], gonorrhea/chlamydia testing in 2010 remained lower than syphilis and lipid testing (39%, 77%, 76%, respectively). Interventions to improve gonorrhea/chlamydia screening are needed. A more targeted screening approach may be warranted.

    Given the significant impact of computing on society, it is important that all cultures, especially underrepresented cultures, are fully engaged in the field of computing to ensure that everyone benefits from the advances in computing. This proposal is focused on the field of high performance computing. The lack of cultural diversity in computing, in particular high performance computing, is especially evident with respect to the following ethnic groups – African Americans, Hispanics, and Native Americans – as well as People with Disabilities. The goal of this proposal is to organize and coordinate a National Laboratory Career Development Workshop focused on underrepresented cultures (ethnic cultures and disability cultures) in high performance computing. It is expected that the proposed workshop will increase the engagement of underrepresented cultures in HPC through increased exposure to the excellent work at the national laboratories. The National Laboratory Workshops are focused on the recruitment of senior graduate students and the retention of junior lab staff through the various panels and discussions at the workshop. Further, the workshop will include a community building component that extends beyond the workshop. The workshop was held was held at the Lawrence Livermore National Laboratory campus in Livermore, CA. from June 14 - 15, 2012. The grant provided funding for 25 participants from underrepresented groups. The workshop also included another 25 local participants in the summer programs at Lawrence Livermore National Laboratory. Below are some key results from the assessment of the workshops: 86% of the participants indicated strongly agree or agree to the statement "I am more likely to consider/continue a career at a national laboratory as a result of participating in this workshop." 77% indicated strongly agree or agree to the statement "I plan to pursue a summer internship at a national laboratory." 100% of the participants indicated strongly

    Although transplant practices have changed over the last decades there is no information on trends in incidence and outcome of cGVHD over time. This study utilized the central database of the Center for International Blood and Marrow Transplant Research (CIBMTR) to describe the time trends for cGVHD incidence, non-relapse mortality, and the risk factors for cGVHD. The 12-year period was divided into three intervals: 1995-1999, 2000-2003, 2004-2007, and included 26,563 patients with acute leukemia, chronic myeloid leukemia and myelodysplastic syndrome. In the multivariate analysis, the incidence of cGVHD was shown to be increased in more recent years (odds ratio= 1.19, p<0.0001) and this trend was still seen when adjusting for donor type, graft type, or conditioning intensity. In patients with cGVHD, non-relapse mortality has decreased over time, but at 5-years there were no significant differences among different time periods. Risk factors for cGVHD were in line with previous studies. This is the first comprehensive characterization of the trends in cGVHD incidence and underscores the mounting need for addressing this major late complication of transplantation in future research.

    With the notable exception of California, states have not made enrollment data for their Affordable Care Act (ACA) Marketplace plans publicly available. Researchers thus have tracked premium trends by calculating changes in the average price for plans offered (a straight average across plans) rather than for plans purchased (a weighted average). Using publicly available enrollment data for Covered California, we found that the average purchased price for all plans was 11.6 percent less than the average offered price in 2014, 13.2 percent less in 2015, and 15.2 percent less in 2016. Premium growth measured by plans purchased was roughly 2 percentage points less than when measured by plans offered in 2014-15 and 2015-16. We observed shifts in consumer choices toward less costly plans, both between and within tiers, and we estimate that a $100 increase in a plan's net annual premium reduces its probability of selection. These findings suggest that the Marketplaces are helping consumers moderate premium cost growth. Project HOPE—The People-to-People Health Foundation, Inc.

    A study was conducted to determine if transporting steelhead, Salmo gairdneri, smolts by barge from Dworshak National Fish Hatchery to a release site in the Columbia River below Bonneville Dam would result in increased returns of adults to the fishery and hatchery. Eight separately identifiable groups of about 30,000 steelhead each were marked and released in 1982. During 1983, over 251,000 smolts were marked - about 30,000 fish for each of four test lots (barged) and four control lots (released into the Clearwater River near the hatchery). The health and status of smoltification of the juvenile fish were monitored from March to the release date for each group. The fish sampled were considered to be in good health and well advanced in smoltification at release. Fish from the control release were recovered at dams and in the estuary along their migration route. Approximately 29% of the fish from the control release were transported from collector dams (Lower Granite, Little Goose, and McNary) as part of the routine transportation program. The relatively large number of 1-ocean age adult steelhead (179) recovered at adult collector dams (Lower Granite, McNary, and Bonneville) and in the Indian fishery (Columbia River Zone 6) indicates a high survival of steelhead released as smolts in the spring of 1982. A large return of 2-ocean age adults is expected in 1984. 3 refs.

While studies exist demonstrating the role of APS in coronary artery bypass graft failure, its role in stent thrombosis is less clearly documented. Also, a literature search of PubMed did not reveal any articles regarding the coexistence of clopidogrel resistance and APS despite increasing awareness of resistance to clopidogrel treatment. We present a case of a 59-year-old male having recurrent myocardial infarction after subacute restenosis of multiple drug-eluting stents despite anticoagulant therapy. The patient had in-stent thrombosis of seven drug-eluting stents in a course of eight days. He was subsequently found to have mild elevation of IgG anticardiolipin (aCL antibody titers and resistance to clopidogrel. Long-term anticoagulation with a combination of low-molecular-weight heparin, clopidogrel, and aspirin has been effective. While the patient's aCL titer level was not elevated above the level required by the current diagnostic criteria for APS, we believe that this patient suffers from the antiphospholipid syndrome. We will discuss some of the controversies surrounding the diagnosis of APS as well as appropriate treatment and recognition of the coexistence of APS and clopidogrel resistance in patients with stent thrombosis.

    Full Text Available Background: Hemisphericity or individual difference in the preference to use the left or the right hemispheric mode of information processing has been associated with various emotion-related differences. For example, the right hemisphericity has been linked with inhibition of emotional expression, feeling of tension, greater impulsivity etc. These observations suggest that right hemisphericity may be associated with greater difficulties in regulating emotions. However, direct empirical tests of such theoretical proposition are very thin. Aim: In view of this, the present study aims to investigate how and to what extent individual difference in hemispheric preference relate to emotion regulation. Materials and Methods: Thirty-two right-handed male subjects in the age range 18 to 20 years were assessed on self-report measures of hemispheric preference and emotion regulation difficulties. The correlation between dimensions of hemispheric preference and difficulties in regulating emotions was computed. A series of stepwise multiple regression analyses were also done to explore the relative significance of various dimensions of hemispheric preference in predicting emotion regulation difficulties. Results: The findings revealed that in general a preference for the right hemispheric mode of information processing was associated with greater emotion regulation difficulties. The correlation analysis indicated that while impulse control difficulties and difficulties in engaging goal directed behavior was associated with preference for almost all the right hemispheric mode of information processing, the nonacceptance of emotional responses and limited access to emotion regulation was related to preference for only global/synthetic (a right hemispheric mode of information processing. Similarly, the lack of emotional clarity facet of emotion regulation difficulties correlated significantly with a preference for the emotional mode of information processing

    Traditional models of drug-seeking behavior have shown that exposure to associated environmental cues can trigger relapse. These learned associations take place during repeated drug administration, resulting in conditioned reinforcement. Although considerable investigation has occurred regarding simple conditioned stimuli, less is known about complex environmental cues, particularly those that may be salient in human addiction. Recent studies indicate that music can serve as a contextual conditioned stimulus in rats and influence drug-seeking behavior during abstinence. The purpose of the present study was to further assess the effectiveness of music as a conditioned stimulus in rats, to determine rats' preferences for two contrasting pieces of music, and to determine rats' preferences for music versus silence. To this end, we created an apparatus that gave instrumental control of musical choice (Miles Davis vs. Beethoven) to the rats themselves. After determining baseline musical preference, animals were conditioned with cocaine (10 mg/kg) to the music they initially preferred least, with alternating conditioning sessions pairing saline with the music preferred most. The animals were subsequently tested in a drug-free state to determine what effect this conditioning had on musical preference. The results indicate that music serves as an effective contextual conditioned stimulus, significantly increasing both musical preference and locomotor activity after repeated cocaine conditioning. Furthermore, we found that rats initially favor silence over music, but that this preference can be altered as a result of cocaine-paired conditioning. These findings demonstrate that, after repeated association with reward (cocaine), music can engender a conditioned context preference in rats; these findings are consistent with other evidence showing that musical contextual cues can reinstate drug-seeking behavior in rats.

    Conservation of biodiversity is determined in part by human preferences. Preferences relevant to conservation have been examined largely via explicit measures (e.g., a self-reported degree of liking), with implicit measures (e.g., preconscious, automatic evaluations) receiving relatively less attention. This is the case despite psychological evidence from other contexts that implicit preferences are more informative of behavior. Thus, the type of measure that predicts conservation intentions for biodiversity is unknown. We conducted three studies to examine conservation intentions in light of people's explicit and implicit preferences toward four endangered species (sea otter, American badger, caribou, yellow-breasted chat) and four biomes (forest, ocean, grassland, tundra). In Study 1 (n = 55), we found that people implicitly preferred caribou most, but explicitly preferred sea otter most, with a significant multiple regression where participants' explicit preferences dictated their stated intended donations for conservation of each species. In Study 2 (n = 57) we found that people implicitly and explicitly preferred forest and ocean over grassland and tundra. Explicit rather than implicit preferences predicted the intended donation for conservation of the ocean biome. Study 3 involved a broader online sample of participants (n = 463) and also found that explicit preferences dictated the intended donations for conservation of biomes and species. Our findings reveal discrepancies between implicit and explicit preferences toward species, but not toward biomes. Importantly, the results demonstrate that explicit rather than implicit preferences predict conservation intentions for biodiversity. The current findings have several implications for conservation and the communication of biodiversity initiatives.

  5. Preference Elicitation in Prioritized Skyline Queries

    Preference queries incorporate the notion of binary preference relation into relational database querying. Instead of returning all the answers, such queries return only the best answers, according to a given preference relation. Preference queries are a fast growing area of database research. Skyline queries constitute one of the most thoroughly studied classes of preference queries. A well known limitation of skyline queries is that skyline preference relations assign the same importance to all attributes. In this work, we study p-skyline queries that generalize skyline queries by allowing varying attribute importance in preference relations. We perform an in-depth study of the properties of p-skyline preference relations. In particular,we study the problems of containment and minimal extension. We apply the obtained results to the central problem of the paper: eliciting relative importance of attributes. Relative importance is implicit in the constructed p-skyline preference relation. The elicitation is ba...

  6. Preference structure for lamb meat consumers. A Spanish case study.

    There is a current tendency in the European Union member countries to cut down on meat consumption. This tendency is not due as much to the traditional income-price factor, but to other attributes whose influence is gaining relative importance. Some of them are: quality, image, health, food safety and changes in people's taste. In addition, the relative importance of different attributes valued by the consumer must be weighed in order to develop marketing strategies which increase lamb meat consumption. In order to determine these preferences, 400 consumers were asked to evaluate different attributes (price, certification, origin, and commercial type) of lamb meat. Results obtained by means of conjoint analysis techniques show that regular consumers as well as occasional ones show a preference for lamb meat type. In this sense, a market share simulation of preferred (suckling and "ternasco") types proved that regular consumers generally prefer suckling lamb to "ternasco" lamb when both are from Castilla-La Mancha.

    Full Text Available Taking the stock market as a whole object, we assume that prior losses and gains are two different factors that can influence risk preference separately. The two factors are introduced as separate explanatory variables into the time-varying GARCH-M (TVRA-GARCH-M model. Then, we redefine prior losses and gains by selecting different reference point to study investors’ time-varying risk preference. The empirical evidence shows that investors’ risk preference is time varying and is influenced by previous outcomes; the stock market as a whole exhibits house money effect; that is, prior gains can decrease investors’ risk aversion while prior losses increase their risk aversion. Besides, different reference points selected by investors will cause different valuation of prior losses and gains, thus affecting investors’ risk preference.

    A model of the auditory process is proposed for performing singers, which incorporates the added signal from bone conduction, as well as the psychological distance for subjective preference of the performer from the acoustic sound field of the stage. The explanatory power of previous scientific studies of vocal stage acoustics has been limited by a lack of an underlying theory of performer preference. Ando's theory, using the autocorrelation function (ACF) for parametrizing temporal factors, was applied to interpretation of singer sound field preference determined by the pair comparison method. Melisma style singing (no lyrics) was shown to increase the preferred delay time of reflections from a mean of 14 ms with lyrics to 23 ms without (pThesis advisor: Yoichi Ando Copies of this thesis are available from the author by inquiry at BRC Acoustics, 1741 First Avenue South, Seattle, WA 98134 USA.

    d-serine is a co-agonist of the N-methyl d-aspartate (NMDA) receptor, an important modulator of glutamatergic excitatory synaptic transmission. We previously reported that oral d-serine ingestion inhibited the intake of highly preferred food and promoted the intake of less preferred food in mice. Here, we analyzed the effects of intraperitoneal (IP) d-serine injections on feeding behavior in mice. We assessed the effects of d-serine during both the acquisition and maintenance of a preference for high-fat diets (HFDs). Aversiveness of IP d-serine was analyzed in the conditioned taste aversion paradigm. The effects on food intake were assessed by providing liquid meals with different fat contents. Finally, we measured brain d-serine and l-serine levels after d-serine administration. We found that IP-injected d-serine effectively inhibited the acquisition of a HFD preference, but failed to prevent expression of a previously learned HFD preference. IP-injected d-serine was not sufficient to condition taste aversion. The effect on HFD preference acquisition was associated with increases in d-serine levels in the cerebral cortex, hypothalamus, and cerebellum. IP-injected d-serine most effectively inhibited the intake of liquid meals with high fat content. This effect was dose-dependent, but the responses varied significantly among male C57BL/6J mice. The differential responses to d-serine were consistent among multiple trials in each mouse. In summary, IP-injected d-serine inhibited HFD intake and the acquisition of an HFD preference. Individual mice with the same genetic background showed different sensitivities to d-serine; thus, d-serine sensitivity may be associated with unidentified traits. Copyright © 2017 The Authors.

    To assess food safety practices, food shopping preferences, and eating behaviors of people diagnosed with Salmonella or Campylobacter infection in the warm seasons, and to identify socioeconomic factors associated with behavior and practices. A cross-sectional survey was conducted among Salmonella and Campylobacter cases with onset of illness from January 1 to March 31, 2013. Multivariable logistic regression analyses examined relationships between socioeconomic position and food safety knowledge and practices, shopping and food preferences, and preferences, perceptions, and knowledge about food safety information on warm days. Respondents in our study engaged in unsafe personal and food hygiene practices. They also carried out unsafe food preparation practices, and had poor knowledge of foods associated with an increased risk of foodborne illness. Socioeconomic position did not influence food safety practices. We found that people's reported eating behaviors and food preferences were influenced by warm weather. Our study has explored preferences and practices related to food safety in the warm season months. This is important given that warmer ambient temperatures are projected to rise, both globally and in Australia, and will have a substantial effect on the burden of infectious gastroenteritis including foodborne disease. Our results provide information about modifiable behaviors for the prevention of foodborne illness in the household in the warm weather and the need for information to be disseminated across the general population. An understanding of the knowledge and factors associated with human behavior during warmer weather is critical for public health interventions on foodborne prevention.

    Current American Cancer Society recommendations for colon cancer screening include optical colonoscopy every 10 years or computed tomography colonography (CTC) every 5 years. Bowel preparation (BP) is currently required for both screening modalities. To compare ACRIN 6664: the National CT Colonography Trial (NCTCT) participant experiences with CTC and optical colonoscopy (OC), procedure preference, and willingness to return for each procedure. Participants from fifteen NCTCT sites, who underwent CTC followed by OC under sedation, were invited to complete questionnaires 2 weeks postexam, asking about procedure preference, physical discomfort, and embarrassment experienced and whether that discomfort and embarrassment was better or worse than expected during BP, CTC, and OC, as well as willingness to return for repeat CTC and OC at different time intervals. A total of 2,310 of 2,600 patients (89%) returned their questionnaires. Of patients reporting a preference, 1,058 (46.6%) preferred CTC, 569 (25.0%) preferred OC, and 626 (27.6%) reported no preference. Participant-reported discomfort worse than expected differed significantly between CTC (32.9%) and OC (5.0%) (Pembarrassment worse than expected with OC were associated with increased intention to adhere with CTC in the future. Conversely, embarrassment experienced during CTC and discomfort worse than expected on CTC were associated with increased intention to adhere with OC in the future. While a larger proportion of participants indicated that they preferred CTC to OC, willingness to undergo repeat CTC compared to OC was limited by unanticipated exam discomfort and embarrassment and CTC's shorter screening interval.

    Human aesthetic preference in the visual domain is reviewed from definitional, methodological, empirical, and theoretical perspectives. Aesthetic science is distinguished from the perception of art and from philosophical treatments of aesthetics. The strengths and weaknesses of important behavioral techniques are presented and discussed, including two-alternative forced-choice, rank order, subjective rating, production/adjustment, indirect, and other tasks. Major findings are reviewed about preferences for colors (single colors, color combinations, and color harmony), spatial structure (low-level spatial properties, shape properties, and spatial composition within a frame), and individual differences in both color and spatial structure. Major theoretical accounts of aesthetic response are outlined and evaluated, including explanations in terms of mere exposure effects, arousal dynamics, categorical prototypes, ecological factors, perceptual and conceptual fluency, and the interaction of multiple components. The results of the review support the conclusion that aesthetic response can be studied rigorously and meaningfully within the framework of scientific psychology.

    Previous research has shown repeatedly that human stature influences mate preferences and mate choice in heterosexuals. In general, it has been shown that tall men and average height women are most preferred by the opposite sex, and that both sexes prefer to be in a relationship where the man is taller than the woman. However, little is known about such partner preferences in homosexual individuals. Based on an online survey of a large sample of non-heterosexual men (N = 541), we found that the majority of men prefer a partner slightly taller than themselves. However, these preferences were dependent on the participant's own height, such that taller men preferred shorter partners, whereas shorter men preferred taller partners. We also examined whether height preferences predicted the preference for dominance and the adoption of particular sexual roles within a couple. Although a large proportion of men preferred to be in an egalitarian relationship with respect to preferred dominance (although not with respect to preferred sexual role), men that preferred a more dominant and more "active" sexual role preferred shorter partners, whereas those that preferred a more submissive and more "passive" sexual role preferred taller partners. Our results indicate that preferences for relative height in homosexual men are modulated by own height, preferred dominance and sex role, and do not simply resemble those of heterosexual women or men.

    We study the relation between the non-tradable shares reform and the refinancing preferences. From the viewpoints of change in market and policy environments led by the reform, we find that right issues dominate before the reform, however, public offerings (including private placement) dominate after reform, which could be attributed to more money encirclement induced by the shift of the public offering mechanism from in discount to in premium after reform and no requirements for large shareholders' participation commitments in public offerings.

    Proliferation of large portions of snack and fast foods parallels dramatic increases in childhood obesity. This study investigates the prevalence, determinants, and consequences of large portions in children's diets. As part of the 2003 Children's Lifestyle and School-performance Study, we surveyed 4,966 children in Nova Scotia regarding their usual portion sizes of french fries, meats, vegetables, and potato chips using three-dimensional graduated food models. We measured heights and weights and assessed dietary intake with the Harvard Youth Adolescent Food Frequency Questionnaire. Diet quality was summarized using the Diet Quality Index International (DQI-I). Parents were surveyed on food habits and socioeconomic background. We used multilevel regression methods to examine determinants of children's large portion size choice and to evaluate the effect of this selection on energy intake, diet quality, and overweight. Children reported preference for portions of french fries, meats, and potato chips that are larger and vegetable portions that are smaller than what is recommended. Children from socioeconomically disadvantaged families or who frequently eat while watching television and in fast-food restaurants preferred larger portions of french fries and potato chips. Consequences of consuming large portions of these foods included poor diet quality and increased energy intake. Consuming large portions of vegetables was associated with lower energy intake and better diet quality. Successful marketing of large portions of french fries and potato chips may be at the expense of diet quality and appropriate energy intake. Policy regulations and nutrition education emphasizing appropriate portion sizes provide opportunities to prevent overweight and improve future health.

    Published studies of consumer feeding preferences using foods that experience autogenic change in mass, numbers, area, etc., on the time scale of a feeding trial fail to employ appropriate statistical analyses to incorporate controls for those food changes occurring in the absence of the consumer. The studies that run controls typically use them to calculate a constant "correction factor", which is subtracted prior to formal data analysis. This procedure constitutes a non-rigorous suppression of variance that overstates the statistical significance of observed differences. The appropriate statistical analysis for preference tests with two foods is usually a simple t-test performed on the between-food differences in loss of mass (or numbers, area, etc.) comparing the results of experimentals with consumers to controls without consumers. Application of this recommended test procedure to an actual data set illustrates how low replication in controls, which is typical of most studies of feeding preference, inhibits detection of an apparently large influence of previous mechanical damage (simulated grazing) in reducing the attractiveness of a brown alga to a sea urchin.

  3. Sociosexuality predicts women's preferences for symmetry in men's faces.

    Although men displaying cues of good physical condition possess traits that are desirable in a mate (e.g., good health), these men are also more likely to possess antisocial characteristics that are undesirable in a long-term partner (e.g., aggression and tendency to infidelity). How women resolve this trade-off between the costs and benefits associated with choosing a mate in good physical condition may lead to strategic variation in women's mate preferences. Because the costs of choosing a mate with antisocial personality characteristics are greater in long- than short-term relationships, women's sociosexuality (i.e., the extent to which they are interested in uncommitted sexual relationships) may predict individual differences in their mate preferences. Here we investigated variation in 99 heterosexual women's preferences for facial symmetry, a characteristic that is thought to be an important cue of physical condition. Symmetry preferences were assessed using pairs of symmetrized and original (i.e., relatively asymmetric) versions of 10 male and 10 female faces. Analyses showed that women's sociosexuality, and their sociosexual attitude in particular, predicted their preferences for symmetry in men's, but not women's, faces; women who reported being more interested in short-term, uncommitted relationships demonstrated stronger attraction to symmetric men. Our findings present new evidence for potentially adaptive variation in women's symmetry preferences that is consistent with trade-off theories of attraction.

Bureau of Justice Statistics, US Department of Justice, Office of Justice Programs, Washington, DC, 2007) recommendations for a teen dating violence resource center. Four focus groups were conducted with urban, African American adolescents (n = 32) aged 13-24 recruited from an urban adolescent clinic's community outreach partners. Qualitative analysis was conducted. Participants assigned a wide range of meanings for the term "relationship drama", and used dating violence using language not typically heard among adults, e.g., "disrespect". Participants described preferences for turning to family or friends before seeking formal services for dating violence, but reported barriers to their ability to rely on these informal sources. When asked to consider formal services, they described their preferred resource center as confidential and safe, with empathetic, non-judgmental staff. Teens also gave insight into preferred ways to outreach and publicize dating violence resources. Findings inform recommendations for youth-specific tailoring of violence screening and intervention efforts. Current evidence that slang terms, i.e., "drama", lack specificity suggests that they should not be integrated within screening protocols

    To determine if the release of health care report cards focused on physician practice quality measures leads to changes in consumers' awareness and use of this information. Data from two rounds of a survey of the chronically ill adult population conducted in 14 regions across the United States, combined with longitudinal information from a public reporting tracking database. Both data were collected as part of the evaluation for Aligning Forces for Quality, a nationwide quality improvement initiative funded by the Robert Wood Johnson Foundation. Using a longitudinal design and an individual-level fixed effects modeling approach, we estimated the impact of community public reporting efforts, measured by the availability and applicability of physician quality reports, on consumers' awareness and use of physician quality information (PQI). The baseline level of awareness was 12.6 percent in our study sample, drawn from the general population of chronically ill adults. Among those who were not aware of PQI at the baseline, when PQI became available in their communities for the first time, along with quality measures that are applicable to their specific chronic conditions, the likelihood of PQI awareness increased by 3.8 percentage points. For the same group, we also find similar increases in the uses of PQI linked to newly available physician report cards, although the magnitudes are smaller, between 2 and 3 percentage points. Specific contents of physician report cards can be an important factor in consumers' awareness and use of PQI. Policies to improve awareness and use of PQI may consider how to customize quality report cards and target specific groups of consumers in dissemination. © Health Research and Educational Trust.

Given the obstacles to ensuring sustainable improvements in water supply infrastructure and the unhygienic handling of water after collection, household water treatment and storage (HWTS) products have been viewed as important mechanisms for increasing access to safe water. Although studies have shown that HWTS technologies can reduce the likelihood of diarrheal illness by about 30%, levels of adoption and continued use remain low. An understanding of household preferences for HWTS products can be used to create demand through effective product positioning and social marketing, and ultimately improve and ensure commercial sustainability and scalability of these products. However, there has been little systematic research on consumer preferences for HWTS products. This paper reports the results of the first state-of-the-art conjoint analysis study of HWTS products. In 2008, we conducted a conjoint analysis survey of a representative sample of households in Andhra Pradesh (AP), India to elicit and quantify household preferences for commercial HWTS products. Controlling for attribute non-attendance in an error components mixed logit model, the study results indicate that the most important features to respondents, in terms of the effect on utility, were the type of product, followed by the extent to which the product removes pathogens, the retail outlet and, the time required to treat 10 L. Holding all other product attributes constant, filters were preferred to combination products and chemical additives. Department stores and weekly markets were the most favorable sales outlets, followed by mobile salespeople. In general, households do not prefer to purchase HWTS products at local shops. Our results can inform the types of products and sales outlets that are likely to be successful in commercial HWTS markets in AP, as well as the influence of different pricing and financing strategies on product demand

    The purpose of this study was to describe patient preferences for uterine preservation and hysterectomy in women with pelvic organ prolapse symptoms and to describe predictors of preference for uterine preservation. This multicenter, cross-sectional study evaluated patient preferences for uterine preservation vs hysterectomy in women with prolapse symptoms who were being examined for initial urogynecologic evaluation. Before meeting the physician, the women completed a questionnaire that asked them to indicate their prolapse treatment preference (uterine preservation vs hysterectomy) for scenarios in which the efficacy of treatment varied. Patient characteristics that were associated with preferences were determined, and predictors for uterine preservation preference were identified with multivariable logistic regression. Two hundred thirteen women participated. Assuming outcomes were equal between hysterectomy and uterine preservation, 36% of the women preferred uterine preservation; 20% of the women preferred hysterectomy, and 44% of the women had no strong preference. If uterine preservation was superior, 46% of the women preferred uterine preservation, and 11% of the women preferred hysterectomy. If hysterectomy was superior, 21% of the women still preferred uterine preservation, despite inferior efficacy. On multivariable logistic regression, women in the South had decreased odds of preferring uterine preservation compared with women in the Northeast (odds ratio [OR], 0.17; 95% CI, 0.05-0.66). Women with at least some college education (OR, 2.87; 95% CI, 1.08-7.62) and those who believed that the uterus is important for their sense of self (OR, 28.2; 95% CI, 5.00-158.7) had increased odds for preferring uterine preservation. A higher proportion of women with prolapse symptoms who were examined for urogynecologic evaluation preferred uterine preservation, compared with hysterectomy. Geographic region, education level, and belief that the uterus is important for

    Integrating mobile phone technologies in addiction treatment is of increasing importance and may optimize patient engagement with their care and enhance the delivery of existing treatment strategies. Few studies have evaluated mobile phone and text message (TM) use patterns in persons enrolled in addiction treatment, and none have assessed the use in safety net, office-based buprenorphine practices. A 28-item, quantitative and qualitative semistructured survey was administered to opiate-dependent adults in an urban, publicly funded, office-based buprenorphine program. Survey domains included demographic characteristics, mobile phone and TM use patterns, and preferences pertaining to their recovery. Surveyors approached 73 of the 155 eligible subjects (47%); 71 respondents completed the survey. Nearly all participants reported mobile phone ownership (93%) and TM use (93%), and most reported "very much" or "somewhat" comfort sending TM (79%). Text message contact with 12-step group sponsors, friends, family members, and counselors was also described (32%). Nearly all preferred having their providers' mobile phone number (94%), and alerting the clinic via TM in the event of a potential relapse to receive both supportive TM and a phone call from their buprenorphine provider was also well received (62%). Mobile phone and TM use patterns and preferences among this sample of office-based buprenorphine participants highlight the potential of adopting patient-centered mobile phone-based interventions in this treatment setting.

    A psychiatric population (n=123) was examined on how music preferences had changed after the onset of a mental disorder. Most patients did not change their previous music preference; this group of patients considered music helpful for their mental state, showed more attractivity and enforcement as personality traits and used music more for emotion modulation. Patients who experienced a preference shift reported that music had impaired them during the time of illness; these patients showed less ego-strength, less confidence and less enforcement and used music less for arousal modulation. A third subgroup stopped listening to music completely after the onset of the mental disorder; these patients attribute less importance to music and also reported that music had impaired their mental state. They showed more ego-strength and used music less for emotion modulation. The results suggest that the use of music in everyday life can be helpful as an emotion modulation strategy. However, some patients might need instructions on how to use music in a functional way and not a dysfunctional one. Psychiatrists and psychotherapists as well as music therapists should be aware of emotion modulation strategies, subjective valence of music and personality traits of their patients. Due to the ubiquity of music, psychoeducative instructions on how to use music in everyday life plays an increasing role in the treatment of mental illness. PMID:26266024

    Recent reports suggest that dietary ethanol, or alcohol, is a supplemental source of calories for some primates. For example, slow lorises (Nycticebus coucang) consume fermented nectars with a mean alcohol concentration of 0.6% (range: 0.0–3.8%). A similar behaviour is hypothesized for aye-ayes (Daubentonia madagascariensis) based on a single point mutation (A294V) in the gene that encodes alcohol dehydrogenase class IV (ADH4), the first enzyme to catabolize alcohol during digestion. The mutation increases catalytic efficiency 40-fold and may confer a selective advantage to aye-ayes that consume the nectar of Ravenala madagascariensis. It is uncertain, however, whether alcohol exists in this nectar or whether alcohol is preferred or merely tolerated by nectarivorous primates. Here, we report the results of a multiple-choice food preference experiment with two aye-ayes and a slow loris. We conducted observer-blind trials with randomized, serial dilutions of ethanol (0–5%) in a standard array of nectar-simulating sucrose solutions. We found that both species can discriminate varying concentrations of alcohol; and further, that both species prefer the highest available concentrations. These results bolster the hypothesized adaptive function of the A294V mutation in ADH4, and a connection with fermented foods, both in aye-ayes and the last common ancestor of African apes and humans.

    Full Text Available Objective. The boarding of patients in Emergency Department (ED hallways when no inpatient beds are available is a major cause of ED crowding. One solution is to board admitted patients in an inpatient rather than ED hallway. We surveyed patients to determine their preference and correlated their responses to real-time National Emergency Department Overcrowding Score (NEDOCS. Methods. This was a survey of admitted patients in the ED of an urban university level I trauma center serving a community of 5 million about their personal preferences regarding boarding. Real-time NEDOCS was calculated at the time each survey was conducted. Results. 99 total surveys were completed during October 2010, 42 (42% patients preferred to be boarded in an inpatient hallway, 33 (33% preferred the ED hallway, and 24 (24% had no preference. Mean (±SD NEDOCS (range 0–200 was 136±46 for patients preferring inpatient boarding, 112±39 for ED boarding, and 119±43 without preference. Male patients preferred inpatient hallway boarding significantly more than females. Preference for inpatient boarding was associated with a significantly higher NEDOCS. Conclusions. In this survey study, patients prefer inpatient hallway boarding when the hospital is at or above capacity. Males prefer inpatient hallway boarding more than females. The preference for inpatient hallway boarding increases as the ED becomes more crowded.

    Background: Food preferences vary substantially among adults and children. Twin studies have established that genes and aspects of the shared family environment both play important roles in shaping children’s food preferences. The transition from childhood to adulthood is characterized by large gains in independence, but the relative influences of genes and the environment on food preferences in late adolescence are unknown. Objective: The aim of this study was to quantify the contribution of genetic and environmental influences on food preferences in older adolescents. Design: Participants were 2865 twins aged 18–19 y from the TEDS (Twins Early Development Study), a large population-based cohort of British twins born during 1994–1996. Food preferences were measured by using a self-report questionnaire of 62 individual foods. Food items were categorized into 6 food groups (fruit, vegetables, meat or fish, dairy, starch foods, and snacks) by using factor analysis. Maximum likelihood structural equation modeling established genetic and environmental contributions to variations in preferences for each food group. Results: Genetic factors influenced a significant and substantial proportion of the variation in preference scores of all 6 food groups: vegetables (0.54; 95% CI: 0.47, 0.59), fruit (0.49; 95% CI: 0.43, 0.55), starchy foods (0.32; 95% CI: 0.24, 0.39), meat or fish (0.44; 95% CI: 0.38, 0.51), dairy (0.44; 95% CI: 0.37, 0.50), and snacks (0.43; 95% CI: 0.36, 0.49). Aspects of the environment that are not shared by 2 twins in a family explained all of the remaining variance in food preferences. Conclusions: Food preferences had a moderate genetic basis in late adolescence, in keeping with findings in children. However, by this older age, the influence of the shared family environment had disappeared, and only aspects of the environment unique to each individual twin influenced food preferences. This finding suggests that shared environmental experiences

    The aim of this study was to assess the construct and predictive validity of a new instrument for self-rating of stress-related Exhaustion Disorder (s-ED). Public healthcare workers and social insurance officers, 85% females, were included (N = 2,683) in a longitudinal study. The s-ED instrument, based on clinical criteria for Exhaustion Disorder, was used at baseline to classify participants into three categories: non-s-ED, light/moderate s-ED and pronounced s-ED. Other assessments include burnout, anxiety, depression and work ability. Sick leave at follow-up after 2 years was defined as 14 days of ongoing sick leave (SA14) or a period of 60 days of sick leave during the last 12 months (SA60). Associations at baseline were expressed as prevalence ratios, and adjusted relative risks (RR) were calculated using Cox regression. At baseline, 16% reported s-ED. Scores of depression, anxiety and burnout and the rate of poor work ability increased with increasing severity of s-ED. Self-reported exhaustion at baseline increased the risk of reporting sickness absence at follow-up; pronounced s-ED RR 2.7; CI 1.8-4.0 for SA14 and RR 3.4; CI 2.3-5.2 for SA60. Self-rated ED corresponded well to established scales for mental health, indicating sufficient construct validity. Individuals reporting s-ED at baseline were more likely to report sickness absence at follow-up, confirming its predictive properties. The s-ED instrument may be a useful tool for occupational health services in identifying human service workers at risk of having or developing a potentially disabling stress-related mental illness.

    The impact of neonicotinoid insecticides on insect pollinators is highly controversial. Sublethal concentrations alter the behaviour of social bees and reduce survival of entire colonies. However, critics argue that the reported negative effects only arise from neonicotinoid concentrations that are greater than those found in the nectar and pollen of pesticide-treated plants. Furthermore, it has been suggested that bees could choose to forage on other available flowers and hence avoid or dilute exposure. Here, using a two-choice feeding assay, we show that the honeybee, Apis mellifera, and the buff-tailed bumblebee, Bombus terrestris, do not avoid nectar-relevant concentrations of three of the most commonly used neonicotinoids, imidacloprid (IMD), thiamethoxam (TMX), and clothianidin (CLO), in food. Moreover, bees of both species prefer to eat more of sucrose solutions laced with IMD or TMX than sucrose alone. Stimulation with IMD, TMX and CLO neither elicited spiking responses from gustatory neurons in the bees' mouthparts, nor inhibited the responses of sucrose-sensitive neurons. Our data indicate that bees cannot taste neonicotinoids and are not repelled by them. Instead, bees preferred solutions containing IMD or TMX, even though the consumption of these pesticides caused them to eat less food overall. This work shows that bees cannot control their exposure to neonicotinoids in food and implies that treating flowering crops with IMD and TMX presents a sizeable hazard to foraging bees.

  18. Inhibitory stimulation of the ventral premotor cortex temporarily interferes with musical beat rate preference.

    Behavioral studies suggest that preference for a beat rate (tempo) in auditory sequences is tightly linked to the motor system. However, from a neuroscientific perspective the contribution of motor-related brain regions to tempo preference in the auditory domain remains unclear. A recent fMRI study (Kornysheva et al. [2010]: Hum Brain Mapp 31:48-64) revealed that the activity increase in the left ventral premotor cortex (PMv) is associated with the preference for a tempo of a musical rhythm. The activity increase correlated with how strongly the subjects preferred a tempo. Despite this evidence, it remains uncertain whether an interference with activity in the left PMv affects tempo preference strength. Consequently, we conducted an offline repetitive transcranial magnetic stimulation (rTMS) study, in which the cortical excitability in the left PMv was temporarily reduced. As hypothesized, 0.9 Hz rTMS over the left PMv temporarily affected individual tempo preference strength depending on the individual strength of tempo preference in the control session. Moreover, PMv stimulation temporarily interfered with the stability of individual tempo preference strength within and across sessions. These effects were specific to the preference for tempo in contrast to the preference for timbre, bound to the first half of the experiment following PMv stimulation and could not be explained by an impairment of tempo recognition. Our results corroborate preceding fMRI findings and suggest that activity in the left PMv is part of a network that affects the strength of beat rate preference.

  19. Otters Increasing - Threats Increasing

    Full Text Available In some parts of Central Europe populations of otters are apparently increasing. Until recently, no research was being conducted on the ecology of otters in mainly artificial habitats like fish farms. Otters are not only a new source of conflict requiring species management, but appear once again threatened by illegal hunting. Austria is dealing with this problem using compensation for otter damage, electric fencing and translocation of problem otters. Despite a rise in illegal killing, Austria does not formally recognise this as a threat.

    The error-related negativity (ERN) is a negative deflection in the event-related potential (ERP) occurring approximately 50 ms after error commission at fronto-central electrode sites and is thought to reflect the activation of a generic error monitoring system. Several studies have reported an increased ERN in clinically anxious children, and suggest that anxious children are more sensitive to error commission--although the mechanisms underlying this association are not clear. We have previously found that punishing errors results in a larger ERN, an effect that persists after punishment ends. It is possible that learning-related experiences that impact sensitivity to errors may lead to an increased ERN. In particular, punitive parenting might sensitize children to errors and increase their ERN. We tested this possibility in the current study by prospectively examining the relationship between parenting style during early childhood and children's ERN approximately 3 years later. Initially, 295 parents and children (approximately 3 years old) participated in a structured observational measure of parenting behavior, and parents completed a self-report measure of parenting style. At a follow-up assessment approximately 3 years later, the ERN was elicited during a Go/No-Go task, and diagnostic interviews were completed with parents to assess child psychopathology. Results suggested that both observational measures of hostile parenting and self-report measures of authoritarian parenting style uniquely predicted a larger ERN in children 3 years later. We previously reported that children in this sample with anxiety disorders were characterized by an increased ERN. A mediation analysis indicated that ERN magnitude mediated the relationship between harsh parenting and child anxiety disorder. Results suggest that parenting may shape children's error processing through environmental conditioning and thereby risk for anxiety, although future work is needed to confirm this

    The theory on the evolution of preferences deals with the endogenous formation of preference relations in strategic situations. It is related to the field of evolutionary game theory. In this book we analyze the role and the influence of general, possibly non-expected utility preferences in such an evolutionary setup. In particular, we demonstrate that preferences which diverge from von Neumann-Morgenstern expected utility may potentially prove to be successful under evolutionary pressures.

    The article tests for structural food preference change in urban China using province-level panel data from 2002 to 2010. We employ the Generalized Quadratic Almost Ideal Demand System to represent consumer preferences and estimate demand for seven food groups in a dynamic setting. This relaxes many of the restrictions on the demand models used in the literature on structural preference change. Our findings suggest that Chinese food preferences are continuing to evolve.

    The diurnal hawkmoth Macroglossum stellatarum is known to feed from a variety of flower species of almost all colours, forms and sizes. A newly eclosed imago, however, has to find its first flower by means of an innate flower template. This study investigates which visual flower features are represented in this template and their relative importance. Newly eclosed imagines were tested for their innate preferences, using artificial flowers made out of coloured paper or projected onto a screen through interference filters. The moths were found to have a strong preference for 440 nm and a weaker preference for 540 nm. The attractiveness of a colour increases with light intensity. The background colour, as well as the spectral composition of the ambient illumination, influences the choice behaviour. Blue paper disks against a yellowish background are chosen much more often than the same disks against a bluish background. Similarly, under ultraviolet-rich illumination, the preference for 540 nm is much more pronounced than under yellowish illumination. Disks of approximately 32 mm in diameter are preferred to smaller and larger ones, and a sectored pattern is more attractive than a ring pattern. Pattern preferences are less pronounced with coloured than with black-and-white patterns. Tests using combinations of two parameters reveal that size is more important than colour and that colour is more important than pattern.

  5. Relative food preference and hedonic judgments in schizophrenia.

    There is a well-documented disruption of the neural network associated with reward evaluation in schizophrenia. This same system is involved in coding the incentive value of food in healthy individuals, but few studies to date have examined anhedonia and its relation to food hedonicity and preference in schizophrenia. Relative preference and hedonic food ratings were examined in schizophrenia patients and healthy controls. In the relative preference task, subjects viewed photographs of food items and selected the one that they most preferred. Hedonic ratings were obtained by asking subjects how much they liked the food stimulus on a scale of 1-5. There were no overall response time differences between the two groups in the relative preference task, but schizophrenia patients showed subtle differences in their hedonic ratings of foods compared with control subjects. Schizophrenia patients gave more positive hedonic ratings for food than did controls, and the use of fewer positive ratings was associated with increased anhedonia, particularly with loss of sexual interest. These results suggest that while making relative preference judgments may be intact, hedonic values attached to food may be altered in schizophrenia, and they may be related to dysfunction in more basic vegetative systems.

    2016-02-22

    In recent years, the expiration of patents for large drug classes has increased the importance of post-patent drug markets. However, previous research has focused solely on patent drug markets. In this study, the authors evaluate the influence of preferred supplier contracts, the German approach to tendering, in post-patent drug markets using a hierarchical market share attraction model. The authors find that preferred supplier contracts are a powerful strategic instrument for generic manufacturers in a highly competitive environment. They quantify the effects of signing a preferred supplier contract and show that brand-name manufacturers are vulnerable to tendering. Therefore, brand-name manufacturers should readjust their strategies and consider including preferred supplier contracts in their marketing mix. In addition, the authors employ a simulation to demonstrate that a first-mover advantage might be gained from signing a preferred supplier contract. Furthermore, their results can be used as a blueprint for decision makers in the pharmaceutical industry to assess the market share effects of different contracting strategies regarding preferred supplier contracts.

  7. Preferences for 'New' Treatments Diminish in the Face of Ambiguity.

    New products usually offer advantages over existing products, but in health care, most new drugs are 'me-too', comparable in effectiveness and side effects to existing drugs, but with a more ambiguous evidence base around adverse effects. Despite this, new treatments drive increased health care spending, suggesting a preference for 'newness' in this setting. We explore (1) whether preferences for treatments labeled 'new' exist and (2) persist once the ambiguity in the evidence base reflecting newness is described. We use a Canadian general population sample (n = 2837) characterized by their innovativeness in adopting new products in normal markets. We found that innovators/early adopters (n = 173) had significant preferences for 'newer' treatments (B = 0.162, p = 0.038) irrespective of comparable benefits and side effects and all respondents had significant preferences for less ambiguity in benefit/side effect estimates. Notably, when 'newness' was combined with ambiguity, no significant preferences for new treatments were observed regardless of respondent innovativeness. We conclude that preferences for new products exist for some people in health care markets but disappear when the implication of ambiguity in the evidence base for new treatments is communicated. Physicians should avoid describing treatments as 'new' or be mindful to qualify the implications of 'new' treatments in terms of evidence ambiguity. Copyright © 2016 John Wiley & Sons, Ltd.

    Full Text Available Abstract Background The completeness of preferences is assumed as one of the axioms of expected utility theory but has been subject to little empirical study. Methods Fifteen non-health professionals was recruited and familiarised with the standard gamble technique. The group then met five times over six months and preferences were elicited independently on 41 scenarios. After individual valuation, the group discussed the scenarios, following which preferences could be changed. Changes made were described and summary measures (mean and median before and after discussion compared using paired t test and Wilcoxon Signed Rank Test. Semi-structured telephone interviews were carried out to explore attitudes to discussing preferences. These were transcribed, read by two investigators and emergent themes described. Results Sixteen changes (3.6% were made to preferences by seven (47% of the fifteen members. The difference between individual preference values before and after discussion ranged from -0.025 to 0.45. The average effect on the group mean was 0.0053. No differences before and after discussion were statistically significant. The group valued discussion highly and suggested it brought four main benefits: reassurance; improved procedural performance; increased group cohesion; satisfying curiosity. Conclusion The hypothesis that preferences are incomplete cannot be rejected for a proportion of respondents. However, brief discussion did not result in substantial number of changes to preferences and these did not have significant impact on summary values for the group, suggesting that incompleteness, if present, may not have an important effect on cost-utility analyses.

    The beneficial effects of peer teaching in medical education have been well-described in the literature. However, it is unclear whether students prefer to be taught by peers in small or large group settings. This study's aim was to identify differences in medical students' preferences and perceptions of small-group versus large-group peer teaching. Questionnaires were administered to medical students in Year 3 and Year 4 (first 2 years of clinical training) at one institution in the United Kingdom to identify their experiences and perceptions of small-and large-group peer teaching. For this study, small-group peer teaching was defined as a tutorial, or similar, taught by peer tutor to a group of 5 students or less. Large-group peer teaching was defined as a lecture, or similar, taught by peer tutors to a group of more than 20 students. Seventy-three students (81% response rate) completed the questionnaires (54% males; median age of 23). Nearly 55% of respondents reported prior exposure to small-group peer teaching but a larger proportion of respondents (86%) had previously attended large-group peer teaching. Of all valid responses, 49% did not have a preference of peer teaching method while 47% preferred small-group peer teaching. The majority of Year 3 students preferred small-group peer teaching to no preference (62.5% vs 37.5%, Fisher's exact test; P = 0.035) whereas most Year 4 students did not report a particular preference. Likert-scale responses showed that the majority of students held negative perceptions about large-group peer teaching, in comparison with small-group peer teaching, with respect to (1) interactivity, (2) a comfortable environment to ask questions, and (3) feedback received. Most respondents in this study did not report a preference for small-versus large-group settings when taught by peers. More Year 3 respondents were likely to prefer small-group peer teaching as opposed to Year 4 respondents.

    Both mimicking and being mimicked induces preference for a target. The present experiments investigate the minimal sufficient conditions for this mimicry-preference link to occur. We argue that mere effector matching between one's own and the other person's movement is sufficient to induce preference, independent of which movement is actually…

    There is a growing interest in individual time and risk preferences. Little is known about how these preferences are formed. It is hypothesised that parents may transmit their preferences to their offspring. This paper examines the correlation in offspring and parental time and risk preferences using data from an annual household survey in Australia (the HILDA survey). Both time and risk preferences are examined and we explored whether the correlation in time and risk preferences varies across the distribution of preferences and across the across the four parent-child dyads (mother/daughter, mother/son, father/daughter, father/son). The results show that there is a significant relationship between parents and their young adult offspring risk and time preference measures. The correlation varies across the distribution of time preferences. The correlation was largest for longer planning horizons. Risk averse parents are more likely to have risk averse children. Except for the father/daughter dyad risk seeking parents are more likely to have risk seeking offspring. Some gender differences were found. The association in parental and offspring time preference was larger for mothers than fathers. Daughters are more likely to be influenced by their mother's risk preferences, however, sons are equally influenced by both parents. The results of this study suggest that the transmission in preferences is more nuanced than previously thought and parental gender may be important.

    Are we facing the end of racial preferences in America? Mr. Clegg thinks we probably are, and examines the role demographics, law, attraction, and vision may play in their demise. What makes preferences still attractive to so many people? Do most Americans share a vision that includes the continued use of racial preferences? Mr. Clegg offers a…
