Recent results in birds, marsupials, rodents and nonhuman primates suggest that phylogeny and ecological factors such as body size, diet and postural habit of a species influence limb usage and the direction and strength of limb laterality. To examine to which extent these findings can be generalised to small-bodied rooting quadrupedal mammals, we studied trees shrews (Tupaia belangeri). We established a behavioural test battery for examining paw usage comparable to small-bodied primates and tested 36 Tupaia belangeri. We studied paw usage in a natural foraging situation (simple food grasping task) and measured the influence of varying postural demands (triped, biped, cling, sit) on paw preferences by applying a forced-food grasping task similar to other small-bodied primates. Our findings suggest that rooting tree shrews prefer mouth over paw usage to catch food in a natural foraging situation. Moreover, we demonstrated that despite differences in postural demand, tree shrews show a strong and consistent individual paw preference for grasping across different tasks, but no paw preference at a population level. Tree shrews showed less paw usage than small-bodied quadrupedal and arboreal primates, but the same paw preference. Our results confirm that individual paw preferences remain constant irrespective of postural demand in some small-bodied quadrupedal non primate and primate mammals which do not require fine motoric control for manipulating food items. Our findings suggest that the lack of paw/hand preference for grasping food at a population level is a universal pattern among those species and that the influence of postural demand on manual lateralisation in quadrupeds may have evolved in large-bodied species specialised in fine manipulations of food items.

To determine the effect of altered lip line on attractiveness and to find preferred lip line for vertical face types in both genders. Cross-sectional analytical study. The Aga Khan University Hospital, Karachi, from May to July 2009. Photographs of two selected subjects were altered to produce three face types for the same individual with the aim of keeping the frame of the smile constant. Lip line was then altered for both the subjects as: both dentitions visible, upper incisors visible, upper incisors and 2 mm gum and 4 mm gum visible. The pictures were rated by different professionals for attractiveness. Descriptive statistics for the raters and multiple factor ANOVA was used to find the most attractive lip line. The total number of raters was 100 with the mean age of 30.3 ± 8 years. The alterations in the smile parameters produced statistically significant difference in the attractiveness of faces, whereas the perception difference was found to be insignificant amongst raters of different professions. Preferred lip line was the one showing only the upper incisors in dolico and mesofacial male and female genders whereas 2 mm gum show was preferred in brachyfacial subjects. The variability in lip line showed significant difference in the perceived attractiveness. Preferred lip lines as the one showing only the upper incisors in dolico and mesofacial male and female genders whereas 2 mm gum show was preferred in brachyfacial subjects.

Most research on the impact of mind-body training does not ask about participants' baseline experience, expectations, or preferences for training. To better plan participant-centered mind-body intervention trials for nurses to reduce occupational stress, such descriptive information would be valuable. We conducted an anonymous email survey between April and June, 2010 of North American nurses interested in mind-body training to reduce stress. The e-survey included: demographic characteristics, health conditions and stress levels; experiences with mind-body practices; expected health benefits; training preferences; and willingness to participate in future randomized controlled trials. Of the 342 respondents, 96% were women and 92% were Caucasian. Most (73%) reported one or more health conditions, notably anxiety (49%); back pain (41%); GI problems such as irritable bowel syndrome (34%); or depression (33%). Their median occupational stress level was 4 (0 = none; 5 = extreme stress). Nearly all (99%) reported already using one or more mind-body practices to reduce stress: intercessory prayer (86%), breath-focused meditation (49%), healing or therapeutic touch (39%), yoga/tai chi/qi gong (34%), or mindfulness-based meditation (18%). The greatest expected benefits were for greater spiritual well-being (56%); serenity, calm, or inner peace (54%); better mood (51%); more compassion (50%); or better sleep (42%). Most (65%) wanted additional training; convenience (74% essential or very important), was more important than the program's reputation (49%) or scientific evidence about effectiveness (32%) in program selection. Most (65%) were willing to participate in a randomized trial of mind-body training; among these, most were willing to collect salivary cortisol (60%), or serum biomarkers (53%) to assess the impact of training. Most nurses interested in mind-body training already engage in such practices. They have greater expectations about spiritual and emotional than

Full Text Available Partnership selection is an important issue in management science. This study proposes a general model based on mixed integer programming and goal-programming analytic hierarchy process (GP-AHP to solve partnership selection problems involving mixed types of uncertain or inconsistent preferences. The proposed approach is designed to deal with crisp, interval, step, fuzzy, or mixed comparison preferences, derive crisp priorities, and improve multiple solution problems. The degree of fulfillment of a decision maker’s preferences is also taken into account. The results show that the proposed approach keeps more solution ratios within the given preferred intervals and yields less deviation. In addition, the proposed approach can treat incomplete preference matrices with flexibility in reducing the number of pairwise comparisons required and can also be conveniently developed into a decision support system.

Animal models have shown that the neural bases of social attachment, sexual preference and pair bonds, depend on dopamine D2-type receptor and oxytocin activity. In addition, studies have demonstrated that cohabitation can shape partner preference via conditioning. Herein, we used rats to explore the development of learned same-sex partner preferences in adulthood as a result of cohabitation during enhanced D2 activity. Experimental Wistar males (N=20), received saline or the D2 agonist (quinpirole) and were allowed to cohabitate during 24 h, with a stimulus male partner that bore almond scent on the back as conditioned stimulus. This was repeated every 4 days, for a total of three trials. Four days later they were drug-free tested for partner preference between the scented male partner and a sexually receptive female. Sexual partner preference was analyzed by measuring frequency and latency for appetitive and consummatory sexual behaviors, as well as non-contact erections. Social preference was also analyzed by measuring the frequency and latency of visits, body contacts and time spent together. Results indicated that only quinpirole-treated males displayed sexual and social preference for the scented male over the sexually receptive female. They spent more time together, displayed more body contacts, more female-like proceptive behaviors, and more non-contact erections. Accordingly, conditioned males appeared to be more sexually aroused and motivated by the known male than by a receptive female. We discuss the implications of this animal model on the formation of learned homosexual partner preferences. Copyright © 2012 Elsevier Inc. All rights reserved.

This study examined preferences for masculinity across faces, bodies, and personality traits in 462 homosexual and bisexual men in China. The impact of sexual self-labels (tops, bottoms, and versatiles) and attitude toward male masculinity on preferences for masculinity were also examined. Participants were asked to select the seven most desirable personality traits for a romantic partner from a list of 32 traits of gender roles. A series of 10 masculinized and feminized dimorphic images of male faces and bodies were then presented to participants, who were required to identify their preferred image. The results indicated that participants preferred more masculine faces, bodies, and personality traits. Significant differences in preferences for masculinity were found between tops, bottoms, and versatiles, with both bottoms and versatiles preferring more masculine faces, bodies, and personality traits than did tops. In addition, preferences for masculinity across faces, bodies, and traits showed a significant positive correlation with each other for all sexual self-labels, indicating a consistent preference for masculinity. Attitude toward male masculinity was significantly correlated with facial, body, and trait preferences; individuals with more rigid attitudes toward male masculinity (low acceptance of femininity in males) preferred more masculine characters. These results indicate a consistent preference for masculinity between both physical features (faces and bodies) and personality traits (instrumentality) that may be affected by observer perception.

Mating preferences for genetic compatibility strictly depend on the interplay of the genotypes of potential partners and are therein fundamentally different from directional preferences for ornamental secondary sexual traits. Thus, the most compatible partner is on average not the one with most pronounced ornaments and vice versa. Hence, mating preferences may often conflict. Here, we present a solution to this problem while investigating the interplay of mating preferences for relatedness (a compatibility criterion) and large body size (an ornamental or quality trait). In previous experiments, both sexes of Pelvicachromis taeniatus, a cichlid fish with mutual mate choice, showed preferences for kin and large partners when these criteria were tested separately. In the present study, test fish were given a conflicting choice between two potential mating partners differing in relatedness as well as in body size in such a way that preferences for both criteria could not simultaneously be satisfied. We show that a sex-specific trade-off occurs between mating preferences for body size and relatedness. For females, relatedness gained greater importance than body size, whereas the opposite was true for males. We discuss the potential role of the interplay between mating preferences for relatedness and body size for the evolution of inbreeding preference.

Type of milk typically consumed, and stated preference, but not health consciousness affect revealed preferences for fat in milk.

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.

Do sex, body size and reproductive condition influence the thermal preferences of a large lizard? A study in Tupinambis merianae.

Body temperature is a key factor in physiological processes, influencing lizard performances; and life history traits are expected to generate variability of thermal preferences in different individuals. Gender, body size and reproductive condition may impose specific requirements on preferred body temperatures. If these three factors have different physiological functions and thermal requirements, then the preferred temperature may represent a compromise that optimizes these physiological functions. Therefore, the body temperatures that lizards select in a controlled environment may reflect a temperature that maximizes their physiological needs. The tegu lizard Tupinambis merianae is one of the largest lizards in South America and has wide ontogenetic variation in body size and sexual dimorphism. In the present study we evaluate intraspecific variability of thermal preferences of T. merianae. We determined the selected body temperature and the rate at which males and females attain their selected temperature, in relation to body size and reproductive condition. We also compared the behavior in the thermal gradient between males and females and between reproductive condition of individuals. Our study show that T. merianae selected body temperature within a narrow range of temperatures variation in the laboratory thermal gradient, with 36.24±1.49°C being the preferred temperature. We observed no significant differences between sex, body size and reproductive condition in thermal preferences. Accordingly, we suggest that the evaluated categories of T. merianae have similar thermal requirements. Males showed higher rates to obtain heat than females and reproductive females, higher rates than non-reproductive ones females. Moreover, males and reproductive females showed a more dynamic behavior in the thermal gradient. Therefore, even though they achieve the same selected temperature, they do it differentially.

Full Text Available Body height influences human mate preferences and choice. A typical finding in Western societies is that women prefer men who are taller than themselves and, equivalently, men prefer women who are shorter than themselves. However, recent reports in non-Western societies (e.g., the Himba in Namibia challenge the view on the universality of such preferences. Here we report on male and female height preferences in two non-Western populations—the Hadza (Tanzania and the Tsimane' (Bolivia—and the relationships between body height preferences and the height of actual partners. In the Hadza, most individuals preferred a sexual dimorphism in stature (SDS with the man being much taller than the woman. Preferences for SDS and actual partner SDS were positively and significantly correlated in both men and women, suggesting that people who preferred larger height differences also had larger height differences with their partners. In the Tsimane', the majority of men preferred an SDS with the man being taller than the woman, but women did not show such a preference. Unlike in the Hadza, SDS preference was not significantly correlated to actual partner SDS. We conclude that patterns of height preferences and choices in the Hadza and Tsimane' are different than those observed in Western societies, and discuss possible causes for the observed differences between non-Western and Western societies.

Henry Loeffler-Wirth

Full Text Available Three-dimensional (3D- body scanning of children and adolescents allows the detailed study of physiological development in terms of anthropometrical alterations which potentially provide early onset markers for obesity. Here, we present a systematic analysis of body scanning data of 2,700 urban children and adolescents in the age range between 5 and 18 years with the special aim to stratify the participants into distinct body shape types and to describe their change upon development. In a first step, we extracted a set of eight representative meta-measures from the data. Each of them collects a related group of anthropometrical features and changes specifically upon aging. In a second step we defined seven body types by clustering the meta-measures of all participants. These body types describe the body shapes in terms of three weight (lower, normal and overweight and three age (young, medium and older categories. For younger children (age of 5-10 years we found a common 'early childhood body shape' which splits into three weight-dependent types for older children, with one or two years delay for boys. Our study shows that the concept of body types provides a reliable option for the anthropometric characterization of developing and aging populations.

Upper shielding body in LMFBR type reactors

1986-01-01

Purpose: Preference is given to the strength and thermal insulation of a roof slab thereby ensuring axial size and improving the operationability upon inserting the control rod in the upper shielding body of LMFBR type reactors. Constitution: In an upper shielding body in which a large rotational plug is rotatably mounted to a circular hole formed at an eccentric position of a roof slab, while a small rotational plug is rotatably mounted to a circular hole disposed at an eccentric position of the large rotational plug and the reactor core upper mechanisms are supported on the small rotational plug, heat insulation layers are attached to the inside of the inner circumferential wall of the roof slab and the outer circumferential wall of the large rotational plug. By attaching the heat insulation layers, the heat conduction between the roof slab and the large rotational plug can be suppressed remarkably, by which occurrence of specific heat pass or local generation of large thermal stresses can be avoided even if difference is resulted to the temperature distribution between them. In this way, functions taking advantage of respective features of the roof slab and the small rotational plug can be obtained to achieve the purpose. (Kamimura, M.)

Mothers are a key influence on adolescent girls' body image. This study aimed to improve understanding of mothers' and daughters' preferences for content in body image interventions designed to assist mothers to promote positive body image among their daughters. British mother-daughter dyads (N=190) viewed descriptions of five evidence-based influences on body image (family, friends, and relationships; appearance-based teasing; media and celebrities; appearance conversations; body acceptance and care). Mothers and daughters each selected the two most important influences to learn about in these interventions. Overall, both mothers and daughters most frequently opted for family, friends, and relationships and body acceptance and care, whereas media and celebrities was their least preferred topic. While the overall sample of mothers and daughters agreed on preferences, Fisher's exact tests showed that within-dyad agreement was low. Recommendations for improving parent and child engagement with, and effectiveness of, child body image interventions delivered to parents are discussed. Copyright © 2016 Elsevier Ltd.

Deficits in dopamine D2/D3 receptor (D2R/D3R) binding availability using PET imaging have been reported in obese humans and rodents. Similar deficits have been reported in cocaine-addicts and cocaine-exposed primates. We found that D2R/D3R binding availability negatively correlated with measures of body weight at the time of scan (ventral striatum), at 1 (ventral striatum) and 2 months (dorsal and ventral striatum) post scan in rats. Cocaine preference was negatively correlated with D2R/D3R binding availability 2 months (ventral striatum) post scan. Our findings suggest that inherent deficits in striatal D2R/D3R signaling are related to obesity and drug addiction susceptibility and that ventral and dorsal striatum serve dissociable roles in maintaining weight gain and cocaine preference. Measuring D2R/D3R binding availability provides a way for assessing susceptibility to weight gain and cocaine abuse in rodents and given the translational nature of PET imaging, potentially primates and humans.

2012-06-01

The effect of writing and reading training on preferred font type and size in low-vision students was evaluated in 35 children. An ophthalmologist confirmed low vision according to ICD-10-CM. Children identified the font type and size they could best read. The writing subtest of the Jebsen-Taylor Hand Function Test, read in 1 min., and legibility as measured by the number of readable written letters were used in evaluating the children. A writing and reading treatment program was conducted, beginning with the child's preferred font type and size, for 3 months, 2 days per week, for 45 min. per day at the child's school. Before treatment, the most preferred font type was Verdana; after treatment, the preferred font type and size changed. Students had gained reading and writing speed after training, but their writing legibility was not significantly better. Training might affect the preferred font type and size of students with low vision. Surprisingly, serif and sans-serif fonts were preferred about equally after treatment.

Cardiac rehabilitation (CR) improves mortality, morbidity and quality of life of cardiovascular patients. However, its uptake is poor especially in the hospitals due to long travel distances and office hours constraints. Community-based CR is a possible solution. To understand the type of community-based CR preferred and identify patient characteristics associated with certain programme combinations. A cross-sectional survey was administered to a randomised list of patients at risk for or with cardiovascular diseases at two community-based CR centres. Participants were presented with nine hypothetical choice sets and asked to choose only one of the two alternative programme combinations in each choice set. Attributes include support group presence, cash incentives, upfront deposit and out-of-pocket cost. The counts for each combination were tallied and corrected for repeats. Chi-square test and logistic regression were performed to understand the characteristics associated with the preferred CR combination. After correcting for repeats, patients most (85.2%) prefer CR programmes with new group activities, support group, cash rewards, deposit and out-of-pocket cost, and few exercise equipment with physiotherapist presence without the need for monitoring equipment. Patients with more than three bedrooms in their house are less likely (OR 0.367; CI 0.17 to 0.80; P=0.011) to choose the choice with no physiotherapist and few equipment available. This is the first study to explore patients' preferences for different types of community CR. Higher income patients prefer physiotherapist presence and are willing to settle for less equipment. Our study serves as a guide for designing future community-based CR programmes.

The issue of cultural universality of waist-to-hip ratio (WHR) attractiveness in women is currently under debate. We tested men's preferences for female WHR in traditional society of Tsimane'(Native Amazonians) of the Bolivian rainforest (N = 66). Previous studies showed preferences for high WHR in traditional populations, but they did not control for the women's body mass.We used a method of stimulus creation that enabled us to overcome this problem. We found that WHR lower than the average WHR in the population is preferred independent of cultural conditions. Our participants preferred the silhouettes of low WHR, but high body mass index (BMI), which might suggest that previous results could be an artifact related to employed stimuli. We found also that preferences for female BMI are changeable and depend on environmental conditions and probably acculturation (distance from the city). Interestingly, the Tsimane' men did not associate female WHR with age, health, physical strength or fertility. This suggests that men do not have to be aware of the benefits associated with certain body proportions - an issue that requires further investigation.

Full Text Available Body dissatisfaction has been related to low self-esteem and depression in adolescents. With regard to the current world wide rise in childhood obesity and common stigmatization of adults and children with obesity, easy to use and cost effective measurements of body dissatisfaction would be helpful in epidemiological research. In the current study, detailed data on body measurements with regard to perceived and ideal body size and body dissatisfaction, as measured with the figure preference task, are presented for a population based sample of 3837 children. Perceived body size correlations to weight, body mass index [BMI], and waist circumference were between 0.41 and 0.54; and to height between 0.12 and 0.21. Odds ratios for lower self-esteem increased with increase in body dissatisfaction. Gender differences in body dissatisfaction were present but not found in relation to self-esteem. It is concluded that the figure preference task yields valuable information in epidemiological studies of children as young as 7.5 years of age. It is argued, that the figure preference task is an additional measurement which theoretically relates to psychological stress in childhood.

2012-01-01

Homogamy for body height has been repeatedly documented in Western societies. Nevertheless, the underlying mechanism is unclear and the reasons for its apparent absence in non-Western societies remain unexplained. This study investigates spousal correlation and mate preference for height in the Japanese population. This study analyses self-reported data on the height of individuals, their parents and their ideal marriage partners, collected by a series of questionnaires on university students. In contrast to a previous study, this study found a significant positive correlation between the heights of Japanese spouses, after controlling for age. It also found a positive correlation between the heights of subjects and of their ideal partners, suggesting that an individual's self-referent preference may contribute to the observed homogamy for height. However, a subject's preference is also influenced by the height of his/her opposite-sex--but not same-sex--parent, where this effect is more prominent in male subjects. This study shows that homogamy for body height is present in the current Japanese population and that it may in part result from an individual's preference. It also indicates a possible role of a sexual imprinting-like mechanism in human mate choice.

Types of conflict, types of relationships and preferred conflict resolution strategies: Implications for constructive conflict resolution programmes

2012-01-01

Full Text Available Constructive conflict resolution programmes are based on the idea that children and youth do no have sufficient knowledge of the procedures and skills for conflict resolution, which is why the conflicts they take part in soon become destructive. Notwithstanding the indubitable practical significance of the constructive conflict resolution programmes, it can be objected that they are not sufficiently based on empirical findings about the characteristics of conflicts in childhood and adolescence. Hence, this paper explores different types of conflict with peers and friends with the aim of determining the preferred conflict resolution strategies and using the obtained results to consider the implications for the improvement of constructive conflict resolution programmes. The research was conducted on the sample of 286 adolescents. The method of hypothetical conflict situations was used for studying the preferred conflict resolution strategies. The key results, which should be taken into account when developing constructive conflict resolution programmes, indicate that the preference for a conflict resolution strategy varies depending on conflict type (problem solving is mostly used in conflicts occurring due to opinion differences and disrespect of agreement, unlike the conflicts arising due to provocations, stubbornness and dishonesty and relationship types (in conflicts with friends, adolescents prefer problem solving, while in peer conflicts they more frequently opt for competition.

Oral fat sensitivity (OFS, the ability to detect fat) may be related to overeating-induced obesity. However, it is largely unknown whether OFS affects taste preference and eating habits. Therefore, we aimed to evaluate (1) the association between body mass index (BMI) and OFS and (2) the relationship of OFS with four types of taste preference (sweet, sour, salty, and bitter) and eating habits using serial concentrations of oleic acid (OA) homogenized in non-fat milk and a self-reported questionnaire. Participants were 25 healthy Japanese individuals (mean age: 27.0 ± 5.6 years), among whom the OA detection threshold was significantly associated with BMI. Participants were divided into two subgroups based on oral sensitivity to 2.8 mM OA: hypersensitive (able to detect 2.8 mM OA, n = 16) and hyposensitive (unable to detect 2.8 mM OA, n = 9). The degree of sweet taste preference of the hypersensitive group was significantly higher than that of the hyposensitive group. Furthermore, there was significantly higher degree of preference for high-fat sweet foods than low-fat sweet foods in the hypersensitive group. There was also a significant inverse correlation between the OA detection threshold and the degree of both spare eating and postprandial satiety. Thus, OFS is associated not only with BMI, but also with the preference for high-fat sweet foods and eating habits. The present study provides novel insights that measuring OFS may be useful for assessing the risk of obesity associated with overeating in countries, including Japan, where BMI is increasing in the population.

Objective Systematic review of research examining consumer preference for the main electronic cigarette (e-cigarette) attributes namely flavor, nicotine strength, and type. Method A systematic search of peer-reviewed articles resulted in a pool of 12,933 articles. We included only articles that meet all the selection criteria: (1) peer-reviewed, (2) written in English, and (3) addressed consumer preference for one or more of the e-cigarette attributes including flavor, strength, and type. Results 66 articles met the inclusion criteria for this review. Consumers preferred flavored e-cigarettes, and such preference varied with age groups and smoking status. We also found that several flavors were associated with decreased harm perception while tobacco flavor was associated with increased harm perception. In addition, some flavor chemicals and sweeteners used in e-cigarettes could be of toxicological concern. Finally, consumer preference for nicotine strength and types depended on smoking status, e-cigarette use history, and gender. Conclusion Adolescents could consider flavor the most important factor trying e-cigarettes and were more likely to initiate vaping through flavored e-cigarettes. Young adults overall preferred sweet, menthol, and cherry flavors, while non-smokers in particular preferred coffee and menthol flavors. Adults in general also preferred sweet flavors (though smokers like tobacco flavor the most) and disliked flavors that elicit bitterness or harshness. In terms of whether flavored e-cigarettes assisted quitting smoking, we found inconclusive evidence. E-cigarette users likely initiated use with a cigarette like product and transitioned to an advanced system with more features. Non-smokers and inexperienced e-cigarettes users tended to prefer no nicotine or low nicotine e-cigarettes while smokers and experienced e-cigarettes users preferred medium and high nicotine e-cigarettes. Weak evidence exists regarding a positive interaction between menthol

Females of the fighting fish Betta splendens have been shown to associate with other B. splendens females in a manner reminiscent of shoaling behavior. Since body coloration varies dramatically in this species, and since body coloration has been shown to affect shoalmate choice in other species of fish, we examined the influence of body coloration on association preferences in female B. splendens. In dichotomous choice tests, B. splendens females spent more time swimming near groups of females (regardless of coloration) than swimming near an empty chamber, and chose to swim near fish of similar coloration to their own when choosing between two distinctly colored groups of females. When examining the interplay between body coloration and group size, focal fish spent more time swimming near larger groups (N=5) of similarly colored fish than swimming near an individual female of similar coloration. However, focal fish showed no preference when presented with an individual female of similar coloration and a larger group of females of dissimilar coloration. These results suggest that association choices in B. splendens females are strongly affected by both body coloration and by group size.

The present study explored the influence of eating habits, body weight and television programme preference on television viewing time and domestic computer usage, after adjusting for sociodemographic characteristics and home media environment indicators. In addition, potential substitution or complementarity in screen time was investigated. Individual level data were collected via questionnaires that were administered to a random sample of 2,946 Germans. The econometric analysis employed a seemingly unrelated bivariate ordered probit model to conjointly estimate television viewing time and time engaged in domestic computer usage. Television viewing and domestic computer usage represent two independent behaviours in both genders and across all age groups. Dietary habits have a significant impact on television watching with less healthy food choices associated with increasing television viewing time. Body weight is found to be positively correlated with television screen time in both men and women, and overweight individuals have a higher propensity for heavy television viewing. Similar results were obtained for age groups where an increasing body mass index (BMI) in adults over 24 years old is more likely to be positively associated with a higher duration of television watching. With respect to dietary habits of domestic computer users, participants aged over 24 years of both genders seem to adopt more healthy dietary patterns. A downward trend in the BMI of domestic computer users was observed in women and adults aged 25-60 years. On the contrary, young domestic computer users 18-24 years old have a higher body weight than non-users. Television programme preferences also affect television screen time with clear differences to be observed between genders and across different age groups. In order to reduce total screen time, health interventions should target different types of screen viewing audiences separately.

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 may

Full Text Available Data on age and body weight at breeding, parity, previous litter size, days open and some descriptive body linear traits from 389 meat-type, prolific Black Bengal goats in Tripura State of India, were collected for 3 and 1/2 years (2007 to 2010 and analyzed using logistic regression model. The objectives of the study were i to evaluate the effect of age and body weight at breeding, parity, previous litter size and days open on litter size of does; and ii to investigate if body linear type traits influenced litter size in meat-type, prolific goats. The incidence of 68.39% multiple births with a prolificacy rate of 175.07% was recorded. Higher age (>2.69 year, higher parity order (>2.31, more body weight at breeding (>20.5 kg and larger previous litter size (>1.65 showed an increase likelihood of multiple litter size when compared to single litter size. There was a strong, positive relationship between litter size and various body linear type traits like neck length (>22.78 cm, body length (>54.86 cm, withers height (>48.85 cm, croup height (>50.67 cm, distance between tuber coxae bones (>11.38 cm and distance between tuber ischii bones (>4.56 cm for discriminating the goats bearing multiple fetuses from those bearing a single fetus.

Arecoline, a major alkaloid in areca nuts, is involved in the pathogenesis of oral diseases. Mammalian taste buds are the structural unit for detecting taste stimuli in the oral cavity. The effects of arecoline on taste bud morphology are poorly understood. Arecoline was injected intraperitoneally (IP) into C57BL/6 mice twice daily for 1-4 weeks. After arecoline treatment, the vallate papillae were processed for electron microscopy and immunohistochemistry analysis of taste receptor proteins (T1R2, T1R3, T1R1, and T2R) and taste associated proteins (α-gustducin, PLCβ2, and SNAP25). Body weight, food intake and water consumption were recorded. A 2-bottle preference test was also performed. The results demonstrated that 1) arecoline treatment didn't change the number and size of the taste buds or taste bud cells, 2) electron microscopy revealed the change of organelles and the accumulation of autophagosomes in type II cells, 3) immunohistochemistry demonstrated a decrease of taste receptor T1R2- and T1R3-expressing cells, 4) the body weight and food intake were markedly reduced, and 5) the sweet preference behavior was reduced. We concluded that the long-term injection of arecoline alters the morphology of type II taste bud cells, retards the growth of mice, and affects discrimination competencies for sweet tastants. © The Author 2015.

Dynamical systems of N point particles without internal degrees of freedom are studied. Their equations of motion are derived from a Fokker-type variational principle with n-body correlations (n = 2,3,...,N), with special emphasis on the case n = 3. The distinction between n-body correlation and n-body effective force is analyzed in detail, with the help of an example. Maximal sets of independent three-body Poincare-invariant scalars are given. An example of three-body correlation formally similar to the usual two-body long-range scalar correlation is given and discussed. (author)

Developmental charts for children with osteogenesis imperfecta, type I (body height, body weight and BMI).

Science.gov (United States)

Graff, Krzysztof; Syczewska, Malgorzata

2017-03-01

Osteogenesis imperfecta (OI) is a rare genetic disorder of type I collagen. Type I is the most common, which is called a non-deforming type of OI, as in this condition, there are no major bone deformities. This type is characterised by blue sclera and vertebral fractures, leading to mild scoliosis. The body height of these patients is regarded as normal, or only slightly reduced, but there are no data proving this in the literature. The aim of this study is the preparation of the developmental charts of children with OI type I. The anthropometric data of 117 patients with osteogenesis imperfecta were used in this study (61 boys and 56 girls). All measurements were pooled together into one database (823 measurements in total). To overcome the problem of the limited number of data being available in certain age classes and gender groups, the method called reverse transformation was used. The body height of the youngest children, aged 2 and 3 years, is less than that of their healthy peers. Children between 4 and 7 years old catch up slightly, but at later ages, development slows down, and in adults, the median body height shows an SDS of -2.7. These results show that children with type I OI are smaller from the beginning than their healthy counterparts, their development slows down from 8 years old, and, ultimately, their body height is impaired. What is Known: • The body height of patients with osteogenesis imperfecta type I is regarded as normal, or only slightly reduced, but in the known literature, there is no measurement data supporting this opinion. What is New: • Children with type I osteogenesis imperfecta are smaller from the beginning than their healthy counterparts, their development slows down from 8 years old and, ultimately, their final body height is impaired. • The developmental charts for the body height, body weight and BMI of children with type I osteogenesis imperfecta are shown.

Children’s preferences for gender-typed objects and colours: a commentary from gender research in Spain

Directory of Open Access Journals (Sweden)

Raúl Navarro

2014-12-01

Full Text Available The main aim of this review was to examine international research on children’s preferences regarding gender-typed objects and colours. Firstly, we provide the theoretical background on gender development to elucidate the ways in which individuals can learn gender stereotypes and develop gender-related preferences. Secondly, we review international research on gender-related preferences. Thirdly, we analyse empirical studies on gender stereotypes in children conducted in Spain and Latin American countries, and show that although gender is a priority research area in these countries, studies on gender development in childhood are lacking. Thus, our aim was to identify a set of issues that provide insights into the development of gender-typed preferences, and that also suggest new directions for researchers in Spanish-speaking countries who are interested in clarifying the relationship between gender and children’s preferences for objects and colours.

Understanding consumer hedonic responses on food products are of greatest interests in global food industry. A global partial least square regression (GPLSR) had been well accepted method for understanding consumer preferences. Recently, individual partial least square regression (IPLSR) was accepted as an alternative method of predicting consumer preferences on given food product, because it utilizes the individual differences on product acceptability. To improve the understanding of what constitutes bar-type snack preference, the relationship between sensory attributes and consumer overall liking for 12 bar-type snacks was determined. Sensory attributes that drive consumer product likings were analyzed using averaged-consumer data by GPLSR. To facilitate the interpretation of individual consumer liking, a dummy matrix for the significant weighted regression coefficients of each consumer derived from IPLSR was created. From the application of GPLSR and IPLSR, current study revealed that chocolate and cereal-flavored bars were preferred over fruit-flavored bars. Attributes connected to chocolate flavor positively influenced consumer overall likings on the global and individual consumer levels. Textural attributes affected liking only on the individual level. To fully capture the importance of sensory attributes on consumer preference, the use of GPLSR in conjunction with IPLSR is recommended. © 2015 Institute of Food Technologists®

The purpose of this study was to explore the relationship between perception of own appearance, Internet pornography consumption, preferences for pornographic actors' appearance, and sexual self-esteem in gay and bisexual men in Norway. An online survey of 477 gay and bisexual men showed that, despite the prevailing muscular and lean gay body ideal, many men with less ideal bodies also preferred to watch pornographic actors with body types similar to their own. Self-perceived attractiveness, having an ideal body type, and viewing Internet pornography in longer sessions each made a unique contribution to higher self-esteem as a sexual partner. Preferring to watch pornographic actors with ideal bodies was not related to sexual self-esteem. The findings underscore the importance for gay or bisexual men of both self-perceived attractiveness and being athletic or young and fit, for a positive self-evaluation of sexual performance and competence.

Full Text Available In this study, two researchers explored student learning preferences in online courses. They used the scholarship of teaching and learning process as a research model, and embedded a web-based survey and online focus groups in the online courses they were teaching. After collecting data, the researchers conducted multiple logistic regression analyses to test their hypothesis that a relationship existed between some student factors and student preferences for types of online learning activities. The results of the data analysis revealed a statistically significant relationship between student age and student preference for certain types of online learning activities. Older students in the study indicated a much stronger preference for videos of the professor lecturing, while younger students tended to prefer more interactive learning strategies. Focus group comments from the older students provide insights into some of the reasons why they found watching video lectures to be helpful for their learning, and comments from younger students illustrate how they learn best in online courses. The researchers offer suggestions for online instructors based on the findings of this study, and they explain why online instructors may find the scholarship of teaching and learning research process especially helpful for both teaching and research efforts.

Full Text Available The paper is concerned with the preference of prior for the Bayesian analysis of the shape parameter of the mixture of Burr type X distribution using the censored data. We modeled the heterogeneous population using two components mixture of the Burr type X distribution. A comprehensive simulation scheme, through probabilistic mixing, has been followed to highlight the properties and behavior of the estimates in terms of sample size, corresponding risks and the proportion of the component of the mixture. The Bayes estimators of the parameters have been evaluated under the assumption of informative and non-informative priors using symmetric and asymmetric loss functions. The model selection criterion for the preference of the prior has been introduced. The hazard rate function of the mixture distribution has been discussed. The Bayes estimates under exponential prior and precautionary loss function exhibit the minimum posterior risks with some exceptions.

Colorectal cancer (CRC) survivors are currently included in a secondary care-led survivorship care programme. Efforts are underway to transfer this survivorship care to primary care, but met with some reluctance by patients and caregivers. This study assesses (1) what caregiver patients prefer to contact for symptoms during survivorship care, (2) what patient factors are associated with a preferred caregiver, and (3) whether the type of symptom is associated with a preferred caregiver. A cross-sectional study of CRC survivors at different time points. For 14 different symptoms, patients reported if they would consult a caregiver, and who they would contact if so. Patient and disease characteristics were retrieved from hospital and general practice records. Two hundred and sixty patients participated (response rate 54%) of whom the average age was 67, 54% were male. The median time after surgery was seven months (range 0-60 months). Patients were divided fairly evenly between tumour stages 1-3, 33% had received chemotherapy. Men, patients older than 65 years, and patients with chronic comorbid conditions preferred to consult their general practitioner (GP). Women, patients with stage 3 disease, and patients that had received chemotherapy preferred to consult their secondary care provider. For all symptoms, patients were more likely to consult their GP, except for (1) rectal blood loss, (2) weight loss, and (3) fear that cancer had recurred, in which case they would consult both their primary and secondary care providers. Patients appreciated all caregivers involved in survivorship care highly; with 8 out of 10 points. CRC survivors frequently consult their GP in the current situation, and for symptoms that could alarm them to a possible recurrent disease consult both their GP and secondary care provider. Patient and tumour characteristics influence patients' preferred caregiver.

The DCE examined six attributes of T2DM treatment each described by two levels: “dosing frequency,” “hemoglobin A1c change,” “weight change,” “type of delivery system,” “frequency of nausea,” and “frequency of hypoglycemia.” Part-worth utilities were estimated using random effects logit models and were used to calculate relative importance (RI values for each attribute. A chi-square test was used to determine differences in preferences for dulaglutide versus liraglutide profiles.Results: A total of 243 participants [mean age: 60.5 (standard deviation 10.9 years; 76.1% male; mean body mass index: 29.8 (standard deviation 5.4 kg/m2] completed the study.

The aim of this trial was to investigate the mechanism of action for body weight loss with semaglutide. This randomised, double-blind, placebo-controlled, two-period crossover trial investigated the effects of 12 weeks of treatment with once-weekly subcutaneous semaglutide, dose-escalated to 1.0 mg, in 30 subjects with obesity. Ad libitum energy intake, ratings of appetite, thirst, nausea and well-being, control of eating, food preference, resting metabolic rate, body weight and body composition were assessed. After a standardised breakfast, semaglutide, compared with placebo, led to a lower ad libitum energy intake during lunch (-1255 kJ; P  energy intake across all ad libitum meals throughout the day (-3036 kJ; P  baseline in mean body weight of 5.0 kg, predominantly from body fat mass. After 12 weeks of treatment, ad libitum energy intake was substantially lower with semaglutide vs placebo with a corresponding loss of body weight observed with semaglutide. In addition to reduced energy intake, likely mechanisms for semaglutide-induced weight loss included less appetite and food cravings, better control of eating and lower relative preference for fatty, energy-dense foods. © 2017 The Authors.

Full Text Available A Delphi survey involving experts in forest preference research was carried out to derive scores for the recreational value of 240 forest stand types across Europe. The survey was organized around four regional panels: Great Britain, Nordic Region, Central Europe, and Iberia. In each region, 60 forest stand types were defined according to five forest management alternatives (FMAs on a continuum of management intensity, four phases of development (establishment, young, medium, and adult, and three tree species types (conifer, broadleaved, and mixed stands of conifer and broadleaved. The resulting scores were examined using conjoint analysis to determine the relative importance of the three structural attributes (FMA, phase of development, and tree species type, and each level or component of the attributes. The findings quantify the extent to which forest visitors prefer a degree of management to unmanaged forest nature reserves across the four regions. Phase of development was shown to make the highest contribution to the recreational value of forests while the contribution of tree species type was shown to be relatively unimportant. While the results are indicative, they provide evidence to support long-term retention and low-impact silviculture in forests where recreation is a primary objective of management.

Aim of the present study was to describe the muscle fibre type composition and body composition of well-trained hammer throwers. Six experienced hammer throwers underwent the following measurements: one repetition maximum in squat, snatch, and clean, standing broad jump, backward overhead shot throw and the hammer throw. Dual x-ray absorptiometry was used for body composition analysis. Fibre type composition and cross sectional area was determined in muscle biopsy samples of the right vastus lateralis. Eight physical education students served as a control group. One repetition maximum in squat, snatch and clean for the hammer throwers was 245 ± 21, 132 ± 13 and 165 ± 12kg, respectively. Lean body mass was higher in hammer throwers (85.9 ± 3. 9kg vs. 62.7 ± 5.1kg (p hammer throwers and 51 ± 8% in the control group (p Hammer throwers had significantly larger type IIA fibres (7703 ± 1171 vs. 5676 ± 1270μm(2), p Hammer throwing performance correlated significantly with lean body mass (r = 0.81, p hammer throwers have larger lean body mass and larger muscular areas occupied by type II fibres, compared with relatively untrained subjects. Moreover, it seems that the enlarged muscle mass of the hammer throwers contributes significantly to the hammer throwing performance. Key pointsWell-trained hammer throwers had increased lean body mass, higher type IIA muscle fibres cross sectional areas, as well as higher bone mineral density, compared to controls.Increased lean body mass was closely related with hammer throwing performance.The relative high percentage of type IIX muscle fibres in vastus lateralis in hammer throwers warrants further investigation.

Associations between body morphology, mating success and mate preferences among Slovak males and females.

Human body morphology is thought to be correlated with sexual behaviour and sociosexuality (defined as an increased willingness to engage in sex without commitment) influences the perception of certain cues of physical attractiveness. Based on a sample of Slovak university students, we investigated relationships between 1) male and female mating success and reported body morphology (body mass index, BMI and waist-to-hip ratio, WHR) and 2) mate preference characteristics and mating success. Both males and females reported a similar number of long-term sexual partners and frequency of engaging in extra-pair copulation (EPC). The mating success of both sexes was positively mediated by self-perceived attractiveness. However, female BMI was inversely associated with mating success whereas increasing BMI was positively associated with male mating success (the total number of lifetime sexual partners) as well as with the likelihood of engaging in EPC. Unrestricted sociosexuality positively correlated with direct and indirect benefits from mating and negatively with the religious/political background of a potential mate and with the desire for a home/ children. These results confirm the hypothesis that human body morphology is associated with sexual behaviour and that cues of direct/indirect benefits in a potential mate positively correlate with sociosexuality.

Full Text Available The aim of this study was to examine the relationship between body type, self-esteem and assertiveness among adolescents of ages between 13 and 19 years. To achieve this aim, the study sampled 56 male and 94 female adolescents of the Senior High School in Accra, Ghana. Results showed that, higher self-esteem leads to assertiveness. Results also showed that body type perception affects self-esteem. It is, therefore, recommended that Guidance and Counselling officers in our schools should educate adolescent students on the three body types and the advantages associated with being one of these body types. This may help prevent developing body dysmorphic disorder, low self-esteem and non-assertiveness among students with negative perceptions of their body types and the possible effects on their personal relationships with peers, general academic performance and in- school and out-of- school life.

2008-02-01

Obesity in severely mentally ill (SMI) populations is an increasing problem, but there is no controlled data regarding the relationship between SMI and weight perception. Fifty patients with schizophrenia and 50 demographically matched control participants were recruited. Weight, height, and body image accuracy were assessed for all participants, and assessments of mood, psychotic symptom severity and anxiety, and preferred modes of weight loss were assessed for the schizophrenia sample. Patients with schizophrenia were significantly more likely to be obese than controls (46% vs. 18%, P < 0.005), and most patients expressed an interest in losing weight. Obese participants with schizophrenia underestimated their body size (11.0%) more than controls (4.9%) (P < 0.05). Patients with schizophrenia are more likely to underestimate their body size, independent of the effects of obesity. However, they also express concern about weight issues and willingness to participate in psychoeducational groups targeted at weight loss.

The development of eating disorders is associated with a body-related attentional bias. Although eating disorders are especially prevalent in adolescence, so far, no study has analyzed gaze patterns and state body image in response to viewing one's own body in youth. To fill this gap, the present study aimed to examine a body-related attentional bias and state body satisfaction in adolescents with various forms of eating disorders. Girls with anorexia nervosa, restrictive type (AN-R; n = 30), anorexia nervosa, binge eating/purging type (AN-BP; n = 26), bulimia nervosa (BN; n = 22), clinical controls with anxiety disorders (n = 20) and healthy controls (n = 43) looked at photographs of their own and a peer's body, while their spontaneous eye movements were recorded. After stimulus presentation, state body satisfaction and individual attractiveness ratings for areas of the presented stimuli were assessed. An analysis of variance revealed that participants of all subgroups showed an attentive preference for unattractive areas of one's own body. Girls with AN-R attended significantly longer to unattractive body areas than both control groups and significantly shorter to attractive body areas than healthy controls. State body dissatisfaction was more prominent in all eating disorder subgroups, with significantly lower scores in BN compared to AN-R. In general, the higher the state body dissatisfaction, the stronger was the deficit orientation on one's own body. The attentional bias towards unattractive body areas, which is most pronounced in AN-R, indicates that interventions aiming to modify distorted attention might be promising in the prevention and treatment of eating disorders in adolescence.

Beta-and gamma-turns in proteins revisited: a new set of amino acid turn-type dependent positional preferences and potentials.

The number of beta-turns in a representative set of 426 protein three-dimensional crystal structures selected from the recent Protein Data Bank has nearly doubled and the number of gamma-turns in a representative set of 320 proteins has increased over seven times since the previous analysis. Beta-turns (7153) and gamma-turns (911) extracted from these proteins were used to derive a revised set of type-dependent amino acid positional preferences and potentials. Compared with previous results, the preference for proline, methionine and tryptophan has increased and the preference for glutamine, valine, glutamic acid and alanine has decreased for beta-turns. Certain new amino acid preferences were observed for both turn types and individual amino acids showed turn-type dependent positional preferences. The rationale for new amino acid preferences are discussed in the light of hydrogen bonds and other interactions involving the turns. Where main-chain hydrogen bonds of the type NH(i + 3) --> CO(i) were not observed for some beta-turns, other main-chain hydrogen bonds or solvent interactions were observed that possibly stabilize such beta-turns. A number of unexpected isolated beta-turns with proline at i + 2 position were also observed. The NH(i + 2) --> CO(i) hydrogen bond was observed for almost all gamma-turns. Nearly 20% classic gamma-turns and 43% inverse gamma-turns are isolated turns.

To determine preferences among patients with type 2 diabetes for content and format of patient education. Using discrete choice methods, we surveyed patients about their preferences for patient education. We investigated preferred content and format regarding education on living well with diabetes, preventing complications, healthy eating, exercising, and psychosocial issues related to diabetes. We obtained usable responses from 2187 patients with type 2 diabetes. Acquiring competencies to live a fulfilling life with diabetes, adjust diet and exercise habits, and prevent complications was significantly more highly valued than was simply being informed about these topics. Patients preferred to be involved in the planning of their diabetes care and valued individually tailored content higher than prescheduled content. Women and younger patients found diet and exercise significantly more important than did men, and patients with poorly controlled diabetes valued all education and support more highly than did patients in better control. Patients with type 2 diabetes prefer to be actively involved in educational activities, to develop competencies to prevent and manage complications, and to involve their social network in supporting them. Future patient education should enhance participation and competence development and include relatives. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

OBJECTIVE. To investigate the effects of weight status, food type and exposure to food and non-food advertisements on children's preference for branded and non-branded foods. DESIGN. A within-subjects, counterbalanced design with control (toy advertisement) and experimental (food advertisement) conditions. Subjects. A total of 37 school students (age: 11-13 years; weight status: 24 lean, 10 overweight, 3 obese). Measurements. Advertisement recall list, two food preference measures; the Leeds Food Preference Measure (LFPM), the Adapted Food Preference Measure (AFPM) and a food choice measure; the Leeds Forced-choice Test (LFCT). RESULTS. Normal weight children selected more branded and non-branded food items after exposure to food advertisements than in the control (toy advertisement) condition. Obese and overweight children showed a greater preference for branded foods than normal weight children per se, and also in this group only, there was a significant correlation between food advertisement recall and the total number of food items chosen in the experimental (food advertisement) condition. CONCLUSION. Exposure to food advertisements increased the preference for branded food items in the normal weight children. This suggests that television food advertisement exposure can produce the same 'obesigenic' food preference response found in overweight and obese children in their normal weight counterparts.

Do Masculine Men Smell Better? An Association Between Skin Color Masculinity and Female Preferences for Body Odor.

A recent study claimed face skin color as a sexually dimorphic variable that influences attractiveness preferences in mate choice. Thereby, skin color may assume the role of a mate quality signal influencing attractiveness preferences. As body odor is linked to attractiveness, this study aimed to explore whether the odors of men with more masculine facial skin color would be evaluated more positively than odors from less masculine men. Female raters were presented with body odors of 18 men and were asked to rate them in various characteristics. Multilevel modeling revealed that the odors of the donors with more masculine color were rated not only as more attractive, more pleasant, and sexier, but also healthier. This indicates that odor associated with men with more masculine skin color is attractive, just as other sexually dimorphic traits. Furthermore, we found a negative relation between skin color masculinity and perceived odor maleness. Regarding this last finding, a new discussion is introduced with respect to the influence of cognitive stereotypes in odor judgments. Altogether, the study supports the possibility that chemosensory signals may be communicating signs of mate quality associated with masculinity. © The Author 2017.

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.

Treatment preferences were assessed using a discrete-choice experiment. Participants completed 16 choice tasks in which they compared pairs of treatment profiles composed of six attributes: A1c decrease, stable blood glucose, low blood glucose, nausea, treatment burden, and out-of-pocket cost. Choice models and willingness-to-pay (WTP estimates were estimated using a conditional logit model and were stratified by educational status. Results: A total of 231 participants with a high school diploma or less education, 156 participants with some college education, and 165 participants with a college degree or more completed the survey. Participants with a college degree or more education were willing to pay more for A1c decreases ($58.84, standard error [SE]: 10.6 than participants who had completed some college ($28.47, SE: 5.53 or high school or less ($17.56, SE: 3.55 (p≤0.01. People with a college education were willing to pay more than people with high school or less to avoid nausea, low blood glucose events during the day/night, or two pills per day. Conclusion: WTP for aspects of diabetes medication differed for people with a college education or more and a high school education or less. Advanced statistical methods might overcome limitations of stratification and advance understanding

This paper develops a dynamic model to illustrate how diet and body weight change when novel food products become available to consumers. We propose a microfounded test to empirically discriminate between habit and taste formation in intertemporal preferences. Moreover, we show that 'novelty consumption' and endogenous preferences can explain the persistent correlation between economic development and obesity. By empirically studying the German reunification, we find that East Germans consumed more novel Western food and gained more weight than West Germans when a larger variety of food products became readily accessible after the fall of the Wall. The observed consumption patterns suggest that food consumption features habit formation. Copyright © 2016 Elsevier B.V. All rights reserved.

Collaboration and implementation of a minimum, standardized set of core global educational and professional competencies seems appropriate given the expanding international evolution of pharmacy practice. However, winnowing down hundreds of competencies from a plethora of local, national and international competency frameworks to select the most highly preferred to be included in the core set is a daunting task. The objective of this paper is to describe a combination of strategies used to ascertain the most highly preferred items among a large number of disparate items. In this case, the items were >100 educational and professional competencies that might be incorporated as the core components of new and existing competency frameworks. Panelists (n = 30) from the European Union (EU) and United States (USA) were chosen to reflect a variety of practice settings. Each panelist completed two electronic surveys. The first survey presented competencies in a Likert-type format and the second survey presented many of the same competencies in an ipsative/forced choice format. Item mean scores were calculated for each competency, the competencies were ranked, and non-parametric statistical tests were used to ascertain the consistency in the rankings achieved by the two strategies. This exploratory study presented over 100 competencies to the panelists in the beginning. The two methods provided similar results, as indicated by the significant correlation between the rankings (Spearman's rho = 0.30, P < 0.09). A two-step strategy using Likert-type and ipsative/forced choice formats in sequence, appears to be useful in a situation where a clear preference is required from among a large number of choices. The ipsative/forced choice format resulted in some differences in the competency preferences because the panelists could not rate them equally by design. While this strategy was used for the selection of professional educational competencies in this exploratory study, it is

Previous studies have shown that individuals with circadian preferences for the evening (wake up later and reach maximum activity in the afternoon) have distorted dietary habits and misregulated body weight. Therefore, the present study was conducted to analyse the possible relationships between 'morningness' or 'eveningness' (chronotype), dietary habits and the level of obesity. Among 400 participants, 171 subjects finished the follow-up period and were evaluated. Anthropometric, clinical and dietary parameters were analysed; the Horne-Östberg test was used to determine chronotype. A hypocaloric-behavioural intervention was performed in the overweight/obese subjects. In normal-weight subjects, the morningness group ingested most of their energy and nutrients at breakfast and lunch, whereas the eveningness group showed a higher intake at dinner, corresponding with their chronotypes. A significant interaction was revealed between chronotype and body mass index regarding the energy and nutrients consumed at dinner (Pfood intake was higher in the eveningness group, but in the overweight subjects the situation was inverse. In addition, the food preferences were related to the chronotype, as the morningness subjects showed a higher intake of fruit (Pfood intake corresponded to the chronotype in the normal-weight subjects; however, the overweight/obese subjects showed intake patterns removed from their physiological rhythms. These findings may indicate a need to design specific diets based not only on the total energy expenditure but also on the chronotype, as an indicator of the biological rhythms.

Full Text Available A study was conducted to investigate the acceptability and preference of meat in Harar and Haramaya towns. The study was carried out from January to March, 2012. One hundred twenty (120 questionnaires were randomly distributed, completed and retrieved for analysis. The results showed that gender had no effect on livestock meat consumption. However, religious had impact on the types of meat consumption. Accordingly, pork was not consumed by both Muslim and Christian, camel meat was consumed by Muslim. Majority of consumers had prefer chicken, beef, and chevon meat as their first choice followed by mutton as compared to other meat. In addition, the study showed a high level of acceptability for the meat of middle aged than old aged. Lean and red color meat got highest acceptability by majority of the consumers than fatty and white meat. The result confirmed that religious and socio-cultural taboos as the major variables that would affect meat preference and consumption of a population in the study area. This study suggested that current preference trend of consumers were not inclusive in that some potential meat animals were hardly utilized or totally ignored from the dish. Therefore, professionals and other stakeholders should made intervention and promote widely utilization of this species to meet animal protein requirement of the community.

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. PMID:26200656

Spontaneous preferences towards possible prey have been little investigated using targets in motion. Preferences of domestic chicks (Gallus gallus) to peck at video-images of stimuli representing live insects moving along their longer body axis (i.e. "forwards") or along the shorter body axis (i.e. "sideways") were investigated. Chicks presented with both types of stimulus displayed a significant preference for pecking at stimuli moving sideways. This preference was already present on day 1 post-hatching, and it strengthened on day 6 for those chicks that had experienced pecking at live insects. Head angles used to fixate the stimuli prior to pecking were also analysed and were consistent (i.e. 30 degrees -35 degrees and 60 degrees -65 degrees ) with those reported for fixation of non-edible targets (larger stimuli at a distance). In a first control experiment the same video-presented stimuli were used but the insect's legs were removed to reduce flickering. In a second control experiment, paper-printed images of the whole insect were used. In both cases, the sideways direction of movement was clearly preferred. Overall, our data show that chicks have a spontaneous preference to peck at video-images resembling live insects moving along their shorter body axis. Sideways movement may constitute a crucial signal attracting chicks' attention and enhancing predatory responses possibly because of stronger stimulation of motion detectors.

A primary goal of the Human Microbiome Project (HMP) was to provide a reference collection of 16S ribosomal RNA gene sequences collected from sites across the human body that would allow microbiologists to better associate changes in the microbiome with changes in health. The HMP Consortium has reported the structure and function of the human microbiome in 300 healthy adults at 18 body sites from a single time point. Using additional data collected over the course of 12-18 months, we used Dirichlet multinomial mixture models to partition the data into community types for each body site and made three important observations. First, there were strong associations between whether individuals had been breastfed as an infant, their gender, and their level of education with their community types at several body sites. Second, although the specific taxonomic compositions of the oral and gut microbiomes were different, the community types observed at these sites were predictive of each other. Finally, over the course of the sampling period, the community types from sites within the oral cavity were the least stable, whereas those in the vagina and gut were the most stable. Our results demonstrate that even with the considerable intra- and interpersonal variation in the human microbiome, this variation can be partitioned into community types that are predictive of each other and are probably the result of life-history characteristics. Understanding the diversity of community types and the mechanisms that result in an individual having a particular type or changing types, will allow us to use their community types to assess disease risk and to personalize therapies.

Forelimb preferences in quadrupedal marsupials and their implications for laterality evolution in mammals

Science.gov (United States)

2013-01-01

Background Acquisition of upright posture in evolution has been argued to facilitate manual laterality in primates. Owing to the high variety of postural habits marsupials can serve as a suitable model to test whether the species-typical body posture shapes forelimb preferences in non-primates or this phenomenon emerged only in the course of primate evolution. In the present study we aimed to explore manual laterality in marsupial quadrupeds and compare them with the results in the previously studied bipedal species. Forelimb preferences were assessed in captive grey short-tailed opossum (Monodelphis domestica) and sugar glider (Petaurus breviceps) in four different types of unimanual behaviour per species, which was not artificially evoked. We examined the possible effects of sex, age and task, because these factors have been reported to affect motor laterality in placental mammals. Results In both species the direction of forelimb preferences was strongly sex-related. Male grey short-tailed opossums showed right-forelimb preference in most of the observed unimanual behaviours, while male sugar gliders displayed only a slight, not significant rightward tendency. In contrast, females in both species exhibited consistent group-level preference of the left forelimb. We failed to reveal significant differences in manual preferences between tasks of potentially differing complexity: reaching a stable food item and catching live insects, as well as between the body support and food manipulation. No influence of subjects’ age on limb preferences was found. Conclusions The direction of sex-related differences in the manual preferences found in quadrupedal marsupials seems to be not typical for placental mammals. We suggest that the alternative way of interhemispheric connection in absence of corpus callosum may result in a fundamentally distinct mechanism of sex effect on limb preferences in marsupials compared to placentals. Our data confirm the idea that non

Chemotherapy can affect taste and smell function. This may contribute to the high prevalence of overweight and metabolic syndrome in testicular cancer survivors (TCS). Aims of the study were to evaluate taste and smell function and possible consequences for dietary intake, food preference, and body composition in TCS treated with cisplatin-based chemotherapy. Fifty TCS, 1-7 years post-chemotherapy, and 50 age-matched healthy men participated. Taste and smell function were measured using taste strips and 'Sniffin' Sticks', respectively. Dietary intake was investigated using a food frequency questionnaire. Food preference was assessed using food pictures varying in taste (sweet/savoury) and fat or protein content. Dual-Energy X-ray Absorptiometry was performed to measure body composition. Presence of metabolic syndrome and hypogonadism were assessed. TCS had a lower total taste function, a higher bitter taste threshold, higher Body Mass Index (BMI), and more (abdominal) fat than controls (p body composition in TCS (p = 0.016). Although taste function was impaired in TCS, this was not related to a different dietary intake compared to controls. Lower testosterone levels were associated with a higher BMI, fat mass, and abdominal fat distribution in TCS. Copyright © 2016 Elsevier Ltd. All rights reserved.

Phenotypic plasticity is a key trait of successful pest species, and may increase the ability to cope with higher, more variable temperatures under climate change. We investigate the plasticity of preferred temperature in a widespread agricultural pest, the wingless grasshopper (Phaulacridium vittatum). Preferred temperature is a measure of thermoregulatory behaviour through habitat selection. It is influenced by melanism, which affects body temperature by determining the amount of radiation absorbed by the body. First we demonstrate that body temperature and preferred temperature in P. vittatum is influenced by melanism, by comparing the preferred temperature of the colour morphs in laboratory thermal gradients and field body temperatures in natural populations. We then test whether preferred temperature changes in response to changes in body temperature, by determining preferred temperature before and after manipulation of melanism by painting. When melanism was manipulated experimentally in live grasshoppers, preferred temperature changed to reflect the thermal qualities of the new colour. The preferred temperature of light grasshoppers increased after they were painted black, and decreased after being painted white. Similarly, dark individuals that were painted white behaved like a light individual, maintaining a lower body temperature. Preferred temperature in P.vittatum is a plastic thermoregulatory response to ambient temperature, mediated by the influence of melanism on body temperature.

Body mass index, waist circumference, body adiposity index, and risk for type 2 diabetes in two populations in Brazil: general and Amerindian.

Full Text Available The use of the anthropometric indices of adiposity, especially body mass index and waist circumference in the prediction of diabetes mellitus has been widely explored. Recently, a new body composition index, the body adiposity index was proposed. The aim of this study was to compare the effectiveness of body mass index, waist circumference, and body adiposity index in the risk assessment for type 2 diabetes mellitus.A total of 1,572 individuals from the general population of Vitoria City, Brazil and 620 Amerindians from the Aracruz Indian Reserve, Brazil were randomly selected. BMI, waist circumference, and BAI were determined according to a standard protocol. Type 2 diabetes mellitus was diagnosed by the presence of fasting glucose ≥126 mg/dL or by the use of antidiabetic drugs.The area under the curve was similar for all anthropometric indices tested in the Amerindian population, but with very different sensitivities or specificities. In women from the general population, the area under the curve of waist circumference was significantly higher than that of the body adiposity index. Regarding risk assessment for type 2 diabetes mellitus, the body adiposity index was a better risk predictor than body mass index and waist circumference in the Amerindian population and was the index with highest odds ratio for type 2 diabetes mellitus in men from the general population, while in women from the general population waist circumference was the best risk predictor.Body adiposity index was the best risk predictor for type 2 diabetes mellitus in the Amerindian population and men from the general population. Our data suggest that the body adiposity index is a useful tool for the risk assessment of type 2 diabetes mellitus in admixture populations.

The purpose of the present study was to assess the effect of preference for three different types of music on magnitude estimation scaling behavior in young adults. Three groups of college students, 10 who liked rock music, 10 who liked big band music, and 10 who liked classical music were tested. Subjects were instructed to assign numerical values to a random series of nine suprathreshold intensity levels of 10-sec, samples of rock music, big band music, and classical music. Analysis indicated that subjects who liked rock music scaled that stimulus differently from those subjects who liked big band and classical music. Subjects who liked big band music scaled that stimulus differently from those subjects who liked rock music and classical music. All subjects scaled classical music similarly regardless of their musical preferences. Results are discussed in reference to the literature concerned with personality and preference as well as spectrographic analyses of the three different types of music used in this study.

Full Text Available INTRODUCTI ON: Foreign body aspiration in pediatrics is a potentially fatal accident which will continue until children explore their surroundings with their hand and mouth. Pediatric aspirations will persist until mankind exists. Not all foreign body aspirations are witnessed hence chances of delay in diagnosing an aspiration are high. Delay in diagnosis depends on site and character of foreign body aspirated. The chest x - ray findings and type of foreign body extracted vary depending on the duration the foreign body remains in airway . OBJECTIVE: To study the X - ray finding in pediatric airway aspiration and its relation to time lapse, the type and site of lodgment of foreign body extracted via bronchoscopy. The type of foreign body in relation to time lapse in aspiration. MATERIAL AND METHODS: This was a prospective study done in Bapuji child health institute and research center, JJM Medical College, Davangere . History and pre bronchoscopy x - Ray finding were noted for 65 children who were posted for suspicious bronchoscopy from August 2011 to September 2013. 11 children were excluded from study as they showed no foreign body on bronchoscopy. Time lapse in aspir ation and seeking medical care was noted. The bronchoscopic findings regarding site of foreign body lodgment and type of foreign body were recorded. The type of foreign body and variation of x - ray picture in relation to time lapse in aspiration were noted. Data collected was analyzed using descriptive statistics. RESULT: It was observed that mean age was 28 months. About 80% of the cases were between 1 to 3 years age. 82% (n=53/54 were radio lucent foreign body, only 1.5% (n=1/54 were radio o paque.

Around 2% of males have red–green dichromacy, which is a genetic disorder of color vision where one type of cone photoreceptor is missing. Here we investigate the color preferences of dichromats. We aim (i) to establish whether the systematic and reliable color preferences of normal trichromatic observers (e.g., preference maximum at blue, minimum at yellow-green) are affected by dichromacy and (ii) to test theories of color preference with a dichromatic sample. Dichromat and normal trichromat observers named and rated how much they liked saturated, light, dark, and focal colors twice. Trichromats had the expected pattern of preference. Dichromats had a reliable pattern of preference that was different to trichromats, with a preference maximum rather than minimum at yellow and a much weaker preference for blue than trichromats. Color preference was more affected in observers who lacked the cone type sensitive to long wavelengths (protanopes) than in those who lacked the cone type sensitive to medium wavelengths (deuteranopes). Trichromats’ preferences were summarized effectively in terms of cone-contrast between color and background, and yellow-blue cone-contrast could account for dichromats’ pattern of preference, with some evidence for residual red–green activity in deuteranopes’ preference. Dichromats’ color naming also could account for their color preferences, with colors named more accurately and quickly being more preferred. This relationship between color naming and preference also was present for trichromat males but not females. Overall, the findings provide novel evidence on how dichromats experience color, advance the understanding of why humans like some colors more than others, and have implications for general theories of aesthetics.

Learning strategy preferences, verbal-visual cognitive styles, and multimedia preferences for continuing engineering education instructional design

Baukal, Charles Edward, Jr.

A literature search revealed very little information on how to teach working engineers, which became the motivation for this research. Effective training is important for many reasons such as preventing accidents, maximizing fuel efficiency, minimizing pollution emissions, and reducing equipment downtime. The conceptual framework for this study included the development of a new instructional design framework called the Multimedia Cone of Abstraction (MCoA). This was developed by combining Dale's Cone of Experience and Mayer's Cognitive Theory of Multimedia Learning. An anonymous survey of 118 engineers from a single Midwestern manufacturer was conducted to determine their demographics, learning strategy preferences, verbal-visual cognitive styles, and multimedia preferences. The learning strategy preference profile and verbal-visual cognitive styles of the sample were statistically significantly different than the general population. The working engineers included more Problem Solvers and were much more visually-oriented than the general population. To study multimedia preferences, five of the seven levels in the MCoA were used. Eight types of multimedia were compared in four categories (types in parantheses): text (text and narration), static graphics (drawing and photograph), non-interactive dynamic graphics (animation and video), and interactive dynamic graphics (simulated virtual reality and real virtual reality). The first phase of the study examined multimedia preferences within a category. Participants compared multimedia types in pairs on dual screens using relative preference, rating, and ranking. Surprisingly, the more abstract multimedia (text, drawing, animation, and simulated virtual reality) were preferred in every category to the more concrete multimedia (narration, photograph, video, and real virtual reality), despite the fact that most participants had relatively little prior subject knowledge. However, the more abstract graphics were only slightly

Dairy cows display a partial preference for being outside, but little is known about what aspects of the outdoor environment are important to cows. The primary aim of this study was to test the preference of lactating dairy cattle for pasture versus an outdoor sand pack during the night. A secondary aim was to determine whether feeding and perching behavior changed when cows were provided outdoor access. A third objective was to investigate how the lying behavior of cows changed when given access to different outdoor areas. Ninety-six lactating pregnant cows were assigned to 8 groups of 12 animals each. After a baseline phase of 2 d in which cows were kept inside the freestall barn, cows were habituated to the outdoor areas by providing them access to each of the 2 options for 24 h. Cows were then given access, in random order by group, to either the pasture (pasture phase) or the sand pack (sand phase). As we tested the 2 outdoor options using space allowances consistent with what would be practical on commercial dairy farms, the space provided on pasture was larger (21,000 m 2 ) than that provided on the sand pack (144 m 2 ). Cows were tested at night (for 2 nights in each condition), from 2000 h until morning milking at approximately 0800 h, as preference to be outdoors is strongest at this time. During the next 3 nights cows were given access to both outside options simultaneously (choice phase). Feeding and perching behaviors were recorded when cows were indoors during the day and night periods. Lying behavior was automatically recorded by HOBO data loggers (Onset, Bourne, MA). Cows spent more time outside in the pasture phase (90.0 ± 5.9%) compared with the sand phase (44.4 ± 6.3%). When provided simultaneous access to both options, cows spent more time on pasture than on the sand pack (90.5 ± 2.6% vs. 0.8 ± 0.5%, respectively). Time spent feeding indoors during the day did not change regardless of what type of outdoor access was provided, but there was a

Few studies have evaluated the attitudes of patients with type 2 diabetes mellitus (T2DM) towards the given dietary plans. In this study, we aimed to evaluate: i) the self-reported adherence of T2DM patients to the prescribed diets; ii) the use of other types of diet schemes; iii) the patients' preferences towards the type of meal plans. A 16 multiple-choice items questionnaire was administered to 500 T2DM patients; 71.2% (356/500) of them had the perception of having received a dietary plan; only 163/356 declared to be fully adherent. The latter had lower BMI (25.8 ± 4.5 vs 29.1 ± 4.5 kg/m 2 , p 1) than patients who were partly adherent. Among patients not following the given diet, 61.8% was eating in accordance to a self-made diet and 20.9% did not follow any diet. Only a few patients (2.4%) had tried a popular diet/commercial program. Most patients preferred either a "sufficiently free" (201/500) or a "free" (218/500) scheme. The use of supplements attracted younger, obese individuals, with higher education, and most managers. In a multinomial regression model, age and diabetes duration were inversely associated with the choice of a "rigid" scheme, diabetes duration and glycated hemoglobin levels were inversely correlated with a "free" diet choice, obesity was associated with a "strategic" scheme choice, while lower education (inversely) and obesity (directly) correlated with the preference for "supplement use". Socio-cultural/individual factors could affect attitudes and preferences of T2DM patients towards diet. These factors should be considered in order to draw an individually tailored dietary plan.

Background An increasing number of newly trained Dutch GPs prefer to work in a group practice and as a non-principal rather than in a single-handed practice. In view of the greater number of female doctors, changing practice preferences, and discussions on future workforce problems, the question is whether male and female GPs were able to realise their initial preferences in the past and will be able to do so in the future. Methods We have conducted longitudinal cohort study of all GPs in the Netherlands seeking a practice between 1980 and 2004. The Netherlands Institute of Health Services Research (NIVEL) in Utrecht collected the data used in this study by means of a postal questionnaire. The overall mean response rate was 94%. Results Over the past 20 years, an increasing proportion of GPs, both male and female, were able to achieve their preference for working in a group practice and/or in a non-principal position. Relatively more women than men have settled in group practices, and more men than women in single-handed practices; however, the practice preference of men and women is beginning to converge. Dropout was highest among the GPs without any specific practice preference. Conclusion The overwhelming preference of male and female GPs for working in group practices is apparently being met by the number of positions (principal or non-principal) available in group practices. The preference of male and female GPs regarding the type of practice and job conditions is expected to converge further in the near future. PMID:17629907

Immune and inflammatory pathways play important roles in the pathogenesis of metabolic disorders. This study investigated the role of toll-like receptor 4 (TLR4) in orosensory detection of dietary lipids and sugars. Taste preferences of TLR4 knockout (KO) and wild-type (WT) male mice under a standard and a high-fat, high-sugar diet were assessed with two-bottle tests. Gene expression of taste signaling molecules was analyzed in the tongue epithelium. The role of TLR4 in food intake and weight gain was investigated in TLR4 KO and WT mice fed a high-fat and high-sugar diet for 12 weeks. Compared to WT mice, TLR4 KO mice showed reduced preference for lipids, sugars, and umami in a two-bottle preference test. The altered taste perception was associated with decreased levels of key taste regulatory molecules in the tongue epithelium. TLR4 KO mice on a high-fat and high-sugar diet consumed less food and drink, resulting in diminished weight gain. TLR4 signaling promotes ingestion of sugar and fat by a mechanism involving increased preference for such obesogenic foods. © 2017 The Obesity Society.

Sport type and interpersonal and intrapersonal predictors of body dissatisfaction in high school female sport participants.

Karr, Trisha M; Davidson, Denise; Bryant, Fred B; Balague, Gloria; Bohnert, Amy M

2013-03-01

Through multiple group structural equation modeling analyses, path models were used to test the predictive effects of sport type and both interpersonal (i.e., mothers' body dissatisfaction, family dynamics) and intrapersonal factors (i.e., athletic self-efficacy, body mass index [BMI]) on high school female sport participants' (N=627) body dissatisfaction. Sport types were classified as esthetic/lean (i.e., gymnastics), non-esthetic/lean (i.e., cross-country), or non-esthetic/non-lean (i.e., softball). Most participants reported low body dissatisfaction, and body dissatisfaction did not differ across sport types. Nevertheless, mothers' body dissatisfaction was positively associated with daughters' body dissatisfaction for non-esthetic/lean and non-esthetic/non-lean sport participants, and high family cohesion was predictive of body dissatisfaction among non-esthetic/lean sport participants. Across sport types, higher BMI was associated with greater body dissatisfaction, whereas greater athletic self-efficacy was associated with lower body dissatisfaction. These findings highlight the complex relationship between interpersonal and intrapersonal factors and body dissatisfaction in adolescent female sport participants. Copyright © 2012.

Mindfulness-based cancer recovery (MBCR) and supportive-expressive therapy (SET) are well-validated psycho-oncological interventions, and we have previously reported health benefits of both programs. However, little is known about patients' characteristics or program preferences that may influence outcomes. Therefore, this study examined moderators of the effects of MBCR and SET on psychological well-being among breast cancer survivors. A multi-site randomized controlled trial was conducted between 2007 and 2012 in two Canadian cities (Calgary and Vancouver). A total of 271 distressed stage I-III breast cancer survivors were randomized into MBCR, SET or a 1-day stress management seminar (SMS). Baseline measures of moderator variables included program preference, personality traits, emotional suppression, and repressive coping. Outcome measures of mood, stress symptoms, quality of life, spiritual well-being, post-traumatic growth, social support, and salivary cortisol were measured pre- and post intervention. Hierarchical regression analyses were used to assess moderator effects on outcomes. The most preferred program was MBCR (55%). Those who were randomized to their preference improved more over time on quality of life and spiritual well-being post-intervention regardless of the actual intervention type received. Women with greater psychological morbidity at baseline showed greater improvement in stress symptoms and quality of life if they received their preferred versus nonpreferred program. Patients' program preference and baseline psychological functioning, rather than personality, were predictive of program benefits. These results suggest incorporating program preference can maximize the efficacy of integrative oncology interventions, and emphasize the methodological importance of assessing and accommodating for preferences when conducting mind-body clinical trials. © The Author 2014.

Experimental aerodynamic study of a car-type bluff body

Conan, Boris; Anthoine, Jérôme; Planquart, Philippe

2011-05-01

The Ahmed body is used as a reference model for fundamental studies of car-type bluff body aerodynamics, in particular focused on the influence of the rear slant angle on the drag coefficient. The objectives of the present work are to obtain reliable drag coefficient comparable to the literature and to explain, based on the nature of the flow, its variation when changing the rear slant angle from 10° to 40°. The drag coefficients measured in both an open and a closed test sections differ by less than 0.5% which proves the reliability and reproducibility of the results. The sensitivity of the drag coefficient to some parameters such as the model roughness or the oncoming boundary layer and the lack of precise information on these parameters in the literature could explain the difference observed with the Ahmed drag coefficient data. The various types of measurement techniques used in the study underline their complementarity. The combination of particle image velocimetry and oil visualization provides a deeper understanding of the flow behaviour around the Ahmed body and a physical interpretation of the drag coefficient evolution.

Full Text Available The goal of this study is to investigate how customers’ gaze, head and body orientations reflect their choices. Although the relationship between human choice and gaze behavior has been well studied, other behaviors such as head and body are unknown. We conducted a two-alternatives-forced-choice task to examine (1 whether preference bias, i.e. a positional bias in gaze, head and body toward the item that was later chosen, exists in choice, (2 when preference bias is observed and when prediction of the resulting choice becomes possible (3 whether human choice is affected when the body orientations are manipulated. We used real non-durable products (cheap snacks and clothing on a shopping shelf. The results showed that there was a significant preference bias in head orientation at the beginning one second when the subjects stood straight toward the shelf, and that the head orientation was more biased toward the selected item than the gaze and the center of pressure at the ending one second. Manipulating body orientation did not affect the result of choice. The preference bias detected by observing the head orientation would be useful in marketing science for predicting customers’ choice.

Lin, Linda; DeCusati, Frank

2016-11-01

Research suggests that peer muscularity norms preferences are related to men's body image, but little information is known about how perceptions of specific peer group norms preferences are related to men's body image disturbances and specific health behaviors. This study investigated how men perceived the muscularity preferences of male, female, close, and distant peers and whether the perceptions of specific peer preferences were related to muscle dysmorphia and steroid use. Data on muscle dysmorphia and the perceptions of peer muscularity norms were collected from 117 male college students. Results indicated that men perceived distant and male peers as having the most exaggerated preferences for muscularity and that those perceptions were not an accurate reflection of their distant male peers' reported preferences. Results also indicated that perceptions of close female peer muscularity preferences were predictive of symptoms of muscle dysmorphia, but this relationship did not exist for other peer groups, suggesting that the perceptions of close female peer preferences may play a role in the development of muscle dysmorphia. No relationship was found between perceptions of peer muscularity preferences and steroid use. © The Author(s) 2015.

To handle the high level radioactive materials in a sealed type hot cell, our company has developed the one body alpha-gamma type manipulator and this is an improved model compared with the previously developed beta-gamma and separated alpha-gamma type manipulators. The successful development of one body alpha-gamma type manipulator means our company has a whole capacity to design and fabricate all kinds of manipulators using in hot cells. Until now most of the manipulators in Korea were imported from other countries. The development of Korean manipulators gives us the easier maintenance and lower price compared to the foreign products. It is also possible to export the Korean manipulators to overseas

Image Feature Types and Their Predictions of Aesthetic Preference and Naturalness

Directory of Open Access Journals (Sweden)

Marc G. Berman

2017-04-01

Full Text Available Previous research has investigated ways to quantify visual information of a scene in terms of a visual processing hierarchy, i.e., making sense of visual environment by segmentation and integration of elementary sensory input. Guided by this research, studies have developed categories for low-level visual features (e.g., edges, colors, high-level visual features (scene-level entities that convey semantic information such as objects, and how models of those features predict aesthetic preference and naturalness. For example, in Kardan et al. (2015a, 52 participants provided aesthetic preference and naturalness ratings, which are used in the current study, for 307 images of mixed natural and urban content. Kardan et al. (2015a then developed a model using low-level features to predict aesthetic preference and naturalness and could do so with high accuracy. What has yet to be explored is the ability of higher-level visual features (e.g., horizon line position relative to viewer, geometry of building distribution relative to visual access to predict aesthetic preference and naturalness of scenes, and whether higher-level features mediate some of the association between the low-level features and aesthetic preference or naturalness. In this study we investigated these relationships and found that low- and high- level features explain 68.4% of the variance in aesthetic preference ratings and 88.7% of the variance in naturalness ratings. Additionally, several high-level features mediated the relationship between the low-level visual features and aaesthetic preference. In a multiple mediation analysis, the high-level feature mediators accounted for over 50% of the variance in predicting aesthetic preference. These results show that high-level visual features play a prominent role predicting aesthetic preference, but do not completely eliminate the predictive power of the low-level visual features. These strong predictors provide powerful insights for

Medical weight loss could change sweet taste threshold and preferences. The decrease in sweet taste preferences may, in turn, help in the maintenance of weight loss. This study examined the association between sweet taste preferences at baseline and weight change during a medical weight management programme and the impact of diet-induced weight loss on sweet taste preferences. Adult patients with body mass index ≥32 kg m -2 were recruited from a medical weight management clinic. Sweet taste preference was assessed using a forced-choice, paired-comparison tracking method before and after a very-low-calorie diet (VLCD). Twenty participants were included in the analysis: mean age was 53.1 (standard deviation [SD]: 11.4) years, and 14 were female. The mean body mass index was 41.4 (SD: 7.5) kg m -2 . The median preferred sucrose concentration before VLCD was 0.45 M. Following VLCD, mean change in weight was -13.3 (SD: 6.6) kg, and percentage weight change was -11.3% (SD: 5.9%). Based on mixed models with and without adjustment for demographic factors, diabetes status and smoking history, preferred sucrose concentration at baseline did not predict change in longer-term body weight. The change of preferred sucrose concentration following 12 weeks of VLCD was not significant ( P -value 0.95). Change in weight during and after VLCD was not associated with sweet taste preferences at baseline. After diet-induced weight loss, sweet taste preferences did not change.

2017-01-01

Background Gynecomastia is a common finding in male subjects which incidence varies widely in the world population. In adolescents, it is frequently temporary but, if it becomes persistent, it generates considerable embarrassment, inducing the patients to seek surgical consultation. Even in patients with good body contour, gynecomastia creates even greater distress considering the special attention given by these subjects to their physical appearance. The authors present their experience in the treatment of gynecomastia comparing different body types of patients with the aim to investigate dissimilar expectations, needs and surgical outcomes thus optimizing the management of the pathological condition, achieving high levels of agreement and reducing unsatisfied patients arising from cosmetic surgery. Materials and Methods Between January 2007 and January 2015, 312 selected patients have been treated surgically for gynecomastia. Patients were grouped according to their physical aspect: 97 were classified as high muscle mass body type (group A), 106 as normal (group B) and 109 as overweight patients (group C). All of them were adults ranging in age between 18 and 52 years. Follow-up ranged from 12 to 60 months. In all cases, an excision of the gland in the form of a subcutaneous mastectomy was performed; the most common surgical access was in the inferior part of the areola. Results No breast cancers were found at the histological examinations. Also, no skin or areola necrosis have been referred, and no recurrence of gynecomastia disorder has been reported. Six cases of seroma (limited to the fatty gynecomastia) and 3 cases of hematomas (requiring immediate surgical revision) were found. Although the patients in group B resulted more distressed by the disorder, higher levels of postoperative satisfaction were recorded in this group. Conclusions The study demonstrates the importance of the different management of the same disorder according to the different patients

Body size misperception is common amongst the general public and is a core component of eating disorders and related conditions. While perennial media exposure to the "thin ideal" has been blamed for this misperception, relatively little research has examined visual adaptation as a potential mechanism. We examined the extent to which the bodies of "self" and "other" are processed by common or separate mechanisms in young women. Using a contingent adaptation paradigm, experiment 1 gave participants prolonged exposure to images both of the self and of another female that had been distorted in opposite directions (e.g., expanded other/contracted self), and assessed the aftereffects using test images both of the self and other. The directions of the resulting perceptual biases were contingent on the test stimulus, establishing at least some separation between the mechanisms encoding these body types. Experiment 2 used a cross adaptation paradigm to further investigate the extent to which these mechanisms are independent. Participants were adapted either to expanded or to contracted images of their own body or that of another female. While adaptation effects were largest when adapting and testing with the same body type, confirming the separation of mechanisms reported in experiment 1, substantial misperceptions were also demonstrated for cross adaptation conditions, demonstrating a degree of overlap in the encoding of self and other. In addition, the evidence of misperception of one's own body following exposure to "thin" and to "fat" others demonstrates the viability of visual adaptation as a model of body image disturbance both for those who underestimate and those who overestimate their own size.

A decision making method based on interval type-2 fuzzy sets: An approach for ambulance location preference

Directory of Open Access Journals (Sweden)

Lazim Abdullah

2018-01-01

Full Text Available Selecting the best solution to deploy an ambulance in a strategic location is of the important variables that need to be accounted for improving the emergency medical services. The selection requires both quantitative and qualitative evaluation. Fuzzy set based approach is one of the well-known theories that help decision makers to handle fuzziness, uncertainty in decision making and vagueness of information. This paper proposes a new decision making method of Interval Type-2 Fuzzy Simple Additive Weighting (IT2 FSAW as to deal with uncertainty and vagueness. The new IT2 FSAW is applied to establish a preference in ambulance location. The decision making framework defines four criteria and five alternatives of ambulance location preference. Four experts attached to a Malaysian government hospital and a university medical center were interviewed to provide linguistic evaluation prior to analyzing with the new IT2 FSAW. Implementation of the proposed method in the case of ambulance location preference suggests that the ‘road network’ is the best alternative for ambulance location. The results indicate that the proposed method offers a consensus solution for handling the vague and qualitative criteria of ambulance location preference.

This study aims to determine preferences of a nationally representative sample of obstetrician/gynecologists (OB/GYNs) regarding cesarean delivery (CD) incision practices for women with morbid obesity (body mass index ≥ 40 kg/m(2)). We conducted an online survey using the American College of Obstetricians and Gynecologists database. We compared physician demographics, practice characteristics, and CD incision type preference. After exclusion of ineligible participants, 247 OB/GYNs completed the survey (42% response rate). In nonemergency CD of morbidly obese women, 84% of physicians preferred a Pfannenstiel skin incision (67% preferring taping the pannus; 17% without taping the pannus). In emergency CD, 66% preferred a Pfannenstiel incision (46% without taping the pannus; 20% with taping the pannus) and 20% a vertical incision. For both emergency and nonemergency CD, there was no difference in incision type preferences by provider years in practice, practice scope, or number of CD performed each year. Given the preference of a Pfannenstiel incision with taping the pannus during CD of morbidly obese women, further investigation is needed to assess the risks and benefits of this incision and the practice of elevating the pannus.

Goal preference shapes confrontations of sexism.

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.

To examine the associations between body mass index (BMI) and physical activity with body image, self-esteem and social support in adolescents with type 1 diabetes compared to adolescents without health conditions. We studied 46 adolescents with type 1 diabetes and 27 comparison adolescents who provided self-reports of height and weight, which were used to calculate BMI z-scores. Participants also completed validated questionnaires that assessed physical activity, body image, self-esteem and social support. No significant group differences were found between adolescents with type 1 diabetes and comparison adolescents in terms of BMI and physical activity. Examination of group and gender revealed that higher BMI was significantly associated with a less positive body image in girls with diabetes only. Higher BMI was associated with poorer self-esteem and lower levels of social support in adolescents with diabetes, particularly girls. Higher levels of physical activity were not associated with a more positive body image and no significant associations were found between physical activity and self-esteem or social support. BMI and physical activity levels of adolescents with type 1 diabetes do not differ from those of adolescents without diabetes. Higher BMI is associated with a less positive body image and poorer psychosocial outcomes, particularly in girls with diabetes. As body image concerns and various psychosocial factors could be precursors to the development of eating-disorder symptoms, future research in adolescents with diabetes with higher BMIs should examine the associations among these variables. Further, it is essential that research on body image take into account gender differences. Copyright © 2014 Canadian Diabetes Association. Published by Elsevier Inc. All rights reserved.

Concordant preferences for actual height and facial cues to height

OpenAIRE

Re, Daniel Edward; Perrett, David I.

Physical height has a well-documented effect on human mate preferences. In general, both sexes prefer opposite-sex romantic relationships in which the man is taller than the woman, while individual preferences for height are affected by a person’s own height. Research in human mate choice has demonstrated that attraction to facial characteristics, such as facial adiposity, may reflect references for body characteristics. Here, we tested preferences for facial cues to height. In general, incre...

Patients with type 2 diabetes mellitus (T2DM) who participate in diabetes management programs have been shown to have better glycemic control and slower disease progression, although program participation remains low. In the USA, increasing participation in diabetes management support programs may also directly impact provider reimbursement, as payments are increasingly based on patient-centered measures. However, little is known about factors that may enhance patient participation. This study aimed at further understanding what is important in diabetes management support from the patients' perspective and at assessing the utilization of various types of diabetes-management programs. A two-phase mixed-methods study was conducted of adult US members of PatientsLikeMe®, an online research network of patients. Phase 1 comprised qualitative interviews with 10 individuals to inform the online survey's contents, aided by literature review. During phase 2, this online survey was completed by 294 participants who reported on their diabetes goals and preferences for T2DM self-management support programs. The majority of the respondents were not participating in any program (65 %), but most had goals of improving diet (77 %), weight loss (71 %), and achieving stable blood glucose levels (71 %). Among those currently participating in programs, clinic, hospital-based, or other health-care professional programs were the most commonly used (51 %). The most preferred type of support was diet/weight-loss support (62 %), while doctors or nurses (61 %) and dietitians (55 %) were the most preferred sources of diabetes support. The low participation in diabetes self-management programs revealed in this study underscores the need for strategies to improve patient engagement. The results revealed support types and formats that patients with T2DM prefer and need. These findings may help improve patient engagement by guiding the future design of more effective diabetes management

Comparing individual preferences for four meditation techniques: Zen, Vipassana (Mindfulness), Qigong, and Mantra.

A significant number of studies have been published examining the mind-body effects of meditation and its clinical efficacy. There are very few studies, however, which directly compare different meditation methods with each other to explore potentially distinct mechanisms and effects, and no studies comparing individual preferences for different methods. As preference is seen as an important factor in consumer healthcare decision making, greater understanding of this aspect is needed as meditation becomes a more widely used therapeutic modality. For this reason a pilot study was conducted to compare four meditation techniques for personal preference. A within-subjects comparison design was employed. A convenience sample of 247 undergraduate university students participated in the study. Participants learned two open observing meditation techniques-Vipassana (Mindfulness) and Zen, and two focused attention techniques-Mantra and Qigong Visualization, practicing one method per week. At the end of a six-week training period participants ranked the four meditation methods in order of personal preference. Ranking of subjective preference of meditations practiced. A within subjects comparison revealed that significantly more participants chose Vipassana or Mantra meditation as their preferred techniques compared with Qigong Visualization and Zen. This study provides information on differences in preference for type of meditation. As the benefits of meditation accrue over time, selecting a method that motivates sustained practice is a critical objective if therapeutic effects are to be achieved. Copyright © 2012 Elsevier Inc.

The procedure described here allows the cloning of PCR fragments containing a recognition site of the restriction endonuclease (Type IIP) used for cloning in the sequence of the insert. A Type IIS endonuclease--a Body Double of the Type IIP enzyme--is used to generate the same protruding palindrome. Thus, the insert can be cloned to the Type IIP site of the vector without digesting the PCR product with the same Type IIP enzyme. We achieve this by incorporating the recognition site of a Type IIS restriction enzyme that cleaves the DNA outside of its recognition site in the PCR primer in such a way that the cutting positions straddle the desired overhang sequence. Digestion of the PCR product by the Body Double generates the required overhang. Hitherto the use of Type IIS restriction enzymes in cloning reactions has only been used for special applications, the approach presented here makes Type IIS enzymes as useful as Type IIP enzymes for general cloning purposes. To assist in finding Body Double enzymes, we summarised the available Type IIS enzymes which are potentially useful for Body Double cloning and created an online program (http://group.szbk.u-szeged.hu/welkergr/body_double/index.html) for the selection of suitable Body Double enzymes and the design of the appropriate primers.

Full Text Available Researchers have proposed that people possess different love schemas and that these schemas may shape romantic preferences and reactions to impending commitments.In Study 1, we tested two hypotheses: Hypothesis 1: Men and women will prefer potential dates who possess an “ideal” love schema (i.e., the secure. Hypothesis 2: If the ideal is unavailable, men and women will prefer potential dates whose love schemas are similar to their own. In order to test these hypotheses, men and women from the University of Hawaii, who varied in love schemas, were asked to indicate their preferences for potential romantic partners who varied in physical attractiveness, body type, and love schemas. It was found that people did indeed prefer the ideal (the secure and (secondarily those who were similar to them in attachment style—be it clingy, skittish, casual, or disinterested.Study 2 was designed to test Hypothesis 3: Participants’ love schemas will shape their cognitions, feelings, and behaviors when they find themselves on the brink of making a serious romantic commitment. In order to test this hypothesis, men and women from the University of Hawaii were surveyed. Again, as predicted, it was found that the more strongly men and women endorsed the secure schema, the more calm and confident (and the less fearful and trapped they felt when confronting pending commitments. The more strongly they endorsed the clingy, skittish, fickle, casual, and uninterested schemas, the less confident and calm and the more fearful and trapped they felt when confronting an impending commitment.

Differences in the process of using liver imaging technologies might be important to patients. This study aimed to investigate preferences for scanning modalities used in diagnosing focal liver lesions. A discrete choice experiment was administered to 504 adults aged 25 ≥years. Respondents made repeated choices between two hypothetical scans, described according to waiting time for scan and results, procedure type, the chance of minor side-effects, and whether further scanning procedures were likely to be required. Choice data were analyzed using mixed-logit models with respondent characteristics used to explain preference heterogeneity. Respondents preferred shorter waiting times, the procedure to be undertaken with a handheld scanner on a couch instead of within a body scanner, no side-effects, and no follow–up scans (p≤.01). The average respondent was willing to wait an additional 2 weeks for the scan if it resulted in avoiding side-effects, 1.5 weeks to avoid further procedures or to be told the results immediately, and 1 week to have the scan performed on a couch with a handheld scanner. However, substantial heterogeneity was observed in the strength of preference for desirable imaging characteristics. An average individual belonging to a general population sub–group most likely to require imaging to characterize focal liver lesions in the United Kingdom would prefer contrast–enhanced ultrasound over magnetic resonance imaging or computed tomography. Insights into the patient perspective around differential characteristics of imaging modalities have the potential to be used to guide recommendations around the use of these technologie

Comparison of whole-body-imaging methods

Currently there are four different devices that have found clinical utility in whole-body imaging. These are the rectilinear scanner, the multicrystal whole-body scanner, the Anger-type camera with a whole-body-imaging table, and the tomoscanner. In this text, the basic theory of operation and a discussion of the advantages and disadvantages in whole-body imaging is presented for each device. When applicable, a comparative assessment of the various devices is also presented. As with all else in life, there is no simple answer to the question ''which total body imaging device is best.'' Institutions with a very heavy total-body-imaging load may prefer to use an already available dual-headed rectilinear scanner system for these studies, rather than invest in a new instrument. Institutions with moderate total-body-imaging loads may wish to invest in moving table or moving camera devices which make total body imaging more convenient but retain the basic flexibility of the camera. The large-field Anger camera with or without motion offers another flexible option to these institutions. The laboratory with a very heavy total body imaging load may select efficiency over flexibility, thereby freeing up other instruments for additional studies. Finally, reliability as well as availability and quality of local service must be considered. After all, design features of an instrument become irrelevant when it is broken down and awaiting repair

Full Text Available Abstract Background All previous studies that investigated the association between abdominal fat distribution and insulin resistance evaluated subcutaneous and visceral fat area and/or volume, but these values were not related to the body type of each subject. In the present study we have examined the association between abdominal fat distribution and peripheral (muscle/hepatic sensitivity to insulin using the visceral to abdominal subcutaneous fat area ratio (VF/SF ratio in male patients with type 2 diabetes mellitus. This ratio defines the predominancy of visceral or subcutaneous abdominal adiposity, independent of the body type of each individual. Methods Thirty-six type 2 diabetic male patients underwent a euglycemic insulin clamp (insulin infusion rate = 40 mU/m2·min with 3-3H-glucose to measure insulin-mediated total body (primarily reflects muscle glucose disposal (TGD and suppression of endogenous (primarily reflects liver glucose production (EGP in response to a physiologic increase in plasma insulin concentration. Abdominal subcutaneous (SF and intraabdominal visceral fat (VF areas were quantitated with magnetic resonance imaging (MRI at the level of L4–5. Results TGD and TGD divided by steady state plasma insulin concentration during the insulin clamp (TGD/SSPI correlated inversely with body mass index (BMI, total fat mass (FM measured by 3H2O, SF and VF areas, while VF/SF ratio displayed no significant relationship with TGD or TGD/SSPI. In contrast, EGP and the product of EGP and SSPI during the insulin clamp (an index hepatic insulin resistance correlated positively with VF/SF ratio, but not with BMI, FM, VF or SF. Conclusion We conclude that, independent of the individual's body type, visceral fat dominant accumulation as opposed to subcutaneous fat accumulation is associated with hepatic insulin resistance, whereas peripheral (muscle insulin resistance is more closely related to general obesity (i.e. higher BMI and total FM

2013-02-01

To test Music Marker Theory (MMT) positing that early adolescents' preferences for nonmainstream types of popular music indicate concurrent and later minor delinquency. MMT was tested in a 4-year longitudinal study (n = 309). The results showed that early fans of different types of rock (eg, rock, heavy metal, gothic, punk), African American music (rhythm and blues, hip-hop), and electronic dance music (trance, techno/hardhouse) showed elevated minor delinquency concurrently and longitudinally. Preferring conventional pop (chart pop) or highbrow music (classic music, jazz), in contrast, was not related to or was negatively related to minor delinquency. Early music preferences emerged as more powerful indicators of later delinquency rather than early delinquency, indicating that music choice is a strong marker of later problem behavior. The mechanisms through which music preferences are linked to minor delinquency are discussed within the framework of MMT.

To deliver evidence-based medicine, clinicians often reference resources that are useful to their respective medical practices. Owing to their busy schedules, however, clinicians typically find it challenging to locate these relevant resources out of the rapidly growing number of journals and articles currently being published. The literature-recommender system may provide a possible solution to this issue if the individual needs of clinicians can be identified and applied. We thus collected from the CiteULike website a sample of 96 clinicians and 6,221 scientific articles that they read. We examined the journal distributions, publication types, reading times, and geographic locations. We then compared the distributions of MeSH terms associated with these articles with those of randomly sampled MEDLINE articles using two-sample Z-test and multiple comparison correction, in order to identify the important topics relevant to clinicians. We determined that the sampled clinicians followed the latest literature in a timely manner and read papers that are considered landmarks in medical research history. They preferred to read scientific discoveries from human experiments instead of molecular-, cellular- or animal-model-based experiments. Furthermore, the country of publication may impact reading preferences, particularly for clinicians from Egypt, India, Norway, Senegal, and South Africa. These findings provide useful guidance for developing personalized literature-recommender systems for clinicians.

Purpose Despite the widely accepted benefits of exercise on chronic disease risk, there remains controversy on the role of exercise in weight loss. This study examined the effect of different exercise types on measures of adiposity across different fat categories. Methods A total of 348 young adults (49% male; 28±4 years), participating in an ongoing observational study, provided valid data over a period of 12 months. Fat mass (FM) and lean mass (LM) were measured via dual x-ray absorptiometry every 3 months. Percent body fat (BF) was calculated and used to differentiate between normal fat, over fat and obese participants. At each measurement time point participants reported engagement (min/week) in aerobic exercise, resistance exercise and other exercise. Results Most participants (93%) reported some exercise participation during the observation period. Total exercise or specific exercise types did not significantly affect subsequent BMI after adjusting for sex, ethnicity, age and baseline values of adiposity and exercise. Resistance exercise affected lean mass (pexercise only affected fat mass (pexercise type positively affected lean mass in normal fat participants (pexercise (p≤0.02) but not with aerobic exercise (p≥0.09). Additionally adjusting for objectively assessed total physical activity level did not change these results. Conclusion Despite the limited effects on BMI, exercise was associated with beneficial changes in body composition. Exercise increased lean mass in normal fat participants and reduced fat mass in overfat and obese adults. Adults with excess body fat may benefit particularly from resistance exercise. PMID:25970664

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.

To examine associations among appetite, snacking, and body type during infant development. We also investigated whether trends in appetite, snacking, and body type continue through time. Children (n=1313) born between April 2000 and March 2004, in Ito City, Shizuoka Prefecture, were enrolled. Data were collected during health checkups at 18 and 36 months of age. The items used for analysis were the child's appetite, snack content, snack-eating style, and gender. The mothers commented on their child's appetite as good, normal, lacking, or irregular. The good and normal responses were grouped under the category good/normal appetite, while lacking and irregular were grouped under the category lacking/irregular appetite. Body types were calculated using an obesity index and classified as underweight, normal, or overweight. Fifteen kinds of snacks at 36 months were classified using cluster analysis. Appetite, snack content, snack-eating style, and body type at 18 and 36 months of age were compared using the McNemar test. Logistic regression was used to determine odds ratios (ORs) and 95% confidence intervals (CIs) for the appetite categories. There were 664 boys (50.6%) and 648 girls (49.4%) in the study (missing=1). The response rate was 56.5%. Snacks were classified by content as meal substitutes, snacks and sweet foods, or healthy snacks. There was no change in appetite at 18 and 36 months of age. By 36 months, snack content, snack-eating style had changed (e.g. solitary snacking increased.). The highest risk factor for appetite at 36 months was lacking/irregular appetite at 18 months (OR: 4.70, CI: 3.07-7.19), eating snacks without time constraints (OR: 1.81, CI: 1.24-2.65), followed by unsupervised snacking (OR: 2.92, CI: 1.45-5.87), and consuming few healthy snacks (OR: 0.69, CI: 0.48-1.00). The risk factors for lacking/irregular appetite at 18 months of age were eating snacks without time constraints (OR: 1.68, CI: 1.13-2.49), receiving snacks on-demand (OR: 1

Landscape aesthetics is closely linked to people's daily life, and a large body of studies has been conducted to understand the public's landscape preferences. These studies commonly focused on comprehensive landscape configuration, yet limited emphasis was placed on the patterns of individual landscape features. This research explored people's preferences towards the composition and patterns of some specific urban features. Questionnaire-based survey was conducted in two cities: Cambridge, UK and Nanjing, China and more than 180 responses were collected, respectively. Respondents from both sites showed similar preferences towards freely growing trees, individual houses, gable roofs and mixed design of green spaces. On the other hand, respondents from Cambridge and Nanjing have different preferences towards the height of trees, the size of green spaces, and the height diversity of buildings. This survey also proved that the factors of age, education, status and length of living have larger influences on landscape preferences than the factors of gender, and major. Furthermore, strong correlations were found between people's aesthetic preferences towards comparative landscape patterns, building types, tree shapes and roof structures. The existence of generally shared landscape preferences makes it feasible to conduct international and standardized projects for acquiring comparable and transferable criteria. The methodology and findings of this research provides landscape planners and decision makers with useful reference to compare, evaluate and improve urban landscape configurations to meet people's needs.

2014-03-01

In 3 experiments, we assessed preference of recently weaned dairy calves for (1) 8 high-energy feed types [barley meal, corn meal, corn gluten feed (CGF), oat meal, rice meal, sorghum meal, wheat meal, and wheat middlings meal]; (2) 6 high-protein feed types [corn gluten meal (CGM), wheat distillers dried grains, rapeseed meal, soybean meal (SBM), sunflower meal, and pea meal]; and (3) 4 mixtures (50:50) of the highest- and lowest-ranked high-energy and high-protein feeds, to assess whether calves maintain preference for feed ingredients that are included in a mixture. In all experiments, pairwise preference tests were conducted between all feed types (28 different pairwise preference tests in experiment 1, 15 tests in experiment 2, and 6 tests in experiment 3). Each pairwise preference test was conducted by offering ad libitum access to both feed types for 6h. All tests were repeated with 20 Holstein calves. Before this study, calves were offered milk replacer at a rate of 4 L/d and a pelleted starter feed ad libitum. After weaning at 62 d of age, each calf was involved in a pairwise preference test at 3 and 5d postweaning. A preference ratio was calculated for each calf in each test as (intake of feed type A)/(intake of feed type A + intake of feed type B). Preference for feed types was ranked across tests in each experiment using pairwise comparison charts. In experiment 1, the highest-ranked high-energy feed type was wheat meal and the lowest ranked were rice meal and CGF. In experiment 2, the highest-ranked high-protein feed type was SBM and the lowest ranked was CGM. According to the preference rankings from experiments 1 and 2, experiment 3 evaluated (50:50) mixtures of SBM + wheat meal, SBM + CGF, CGM + wheat meal, and CGM + CGF. The mixture of SBM + wheat meal was highest ranked, CGM + CGF was lowest ranked, and the mixtures containing one high-ranked and one low-ranked feed ingredient (SBM + CGF and CGM + wheat meal) were ranked equally. The results of

Condition-dependent female preference for male genitalia length is based on male reproductive tactics.

2017-12-06

There is extensive morphological variation of male genitalia across animals with internal fertilization, even among closely related species. Most studies attempting to explain this extraordinary diversity have focused on processes that occur post-copula (e.g. sperm competition, cryptic female choice). Only a few studies have focused on the pre-copula process of female preference. In addition, the extent to which this variation could be associated with the use of different reproductive tactics has yet to be explored. Here, we show that female preference for male genitalia length in two livebearing fishes depends on the type of reproductive tactic of the males being evaluated as well as the body condition of the female. In a species where all males coax females to acquire matings (courters), females preferred males with short genitalia. In a species with genetically influenced alternative reproductive tactics (courter males that only court and produce courter sons, sneaker males that use the coercive tactic of sneak chase and produce sneaker sons), female preference depended on an interaction between male tactic and female condition: females in good condition preferred courter males with short genitalia, and sneaker males with long genitalia. Our results suggest that female preference for male traits favourable to their sons may be an important factor contributing to the diversification of male genitalia. Despite the contrasting selection for genitalia length that our female preference tests suggest, we found no significant differences in genitalia length between coaxing (courters) and coercive (sneakers) males. Our study represents a starting point to more clearly understand the role of alternative reproductive tactics and variation in female mate preference in the evolution of male genitalia. © 2017 The Author(s).

Drosophila DH31 Neuropeptide and PDF Receptor Regulate Night-Onset Temperature Preference.

Science.gov (United States)

Goda, Tadahiro; Tang, Xin; Umezaki, Yujiro; Chu, Michelle L; Hamada, Fumika N

2016-11-16

Body temperature exhibits rhythmic fluctuations over a 24 h period (Refinetti and Menaker, 1992) and decreases during the night, which is associated with sleep initiation (Gilbert et al., 2004; Kräuchi, 2007a,b). However, the underlying mechanism of this temperature decrease is largely unknown. We have previously shown that Drosophila exhibit a daily temperature preference rhythm (TPR), in which their preferred temperatures increase during the daytime and then decrease at the transition from day to night (night-onset) (Kaneko et al., 2012). Because Drosophila are small ectotherms, their body temperature is very close to that of the ambient temperature (Stevenson, 1985), suggesting that their TPR generates their body temperature rhythm. Here, we demonstrate that the neuropeptide diuretic hormone 31 (DH31) and pigment-dispersing factor receptor (PDFR) contribute to regulate the preferred temperature decrease at night-onset. We show that PDFR and tethered-DH31 expression in dorsal neurons 2 (DN2s) restore the preferred temperature decrease at night-onset, suggesting that DH31 acts on PDFR in DN2s. Notably, we previously showed that the molecular clock in DN2s is important for TPR. Although PDF (another ligand of PDFR) is a critical factor for locomotor activity rhythms, Pdf mutants exhibit normal preferred temperature decreases at night-onset. This suggests that DH31-PDFR signaling specifically regulates a preferred temperature decrease at night-onset. Thus, we propose that night-onset TPR and locomotor activity rhythms are differentially controlled not only by clock neurons but also by neuropeptide signaling in the brain. Body temperature rhythm (BTR) is fundamental for the maintenance of functions essential for homeostasis, such as generating metabolic energy and sleep. One major unsolved question is how body temperature decreases dramatically during the night. Previously, we demonstrated that a BTR-like mechanism, referred to as temperature preference rhythm (TPR

Full Text Available Pythium species and environmental factors in various types of water bodies (2 springs, 2 rivers, 3 ponds and 6 different trophic lakes were studied. Samples of water were collected every two months (springs, rivers, ponds and every three months (lakes in the years 1996-1999 for hydrochemical analysis and in order to determine the Pythium species content. From springs rivers and ponds collected were also ice blocks for determinations of presence of Pythium species. Buckwheatand hemp-seeds, cellophane and snake exuviae were used as bait. Forty-five species of Pythium were found in various types of water bodies. Pythium acanthicum, P. complectens, P. complens, P. diameson, P. dissimile, P. elongatum, P. lucens, P. megalacanthum, P. nagae, P. oedochilum, P. oryzae, P. palingenes, P. periilum and P. polysporum were recorded for the first time in Poland. The largest mean number of species was observed in spring Cypisek, a bit fewer in spring Jaroszówka and lake Białe (oligotrophic-like waters. The lowest mean number of Pythium species was noted in pond Akcent and Pałacowy (polytrophic waters. In all types of water bodies the higest mean number of species was found in winter, and the lowest in summer.

The growing importance of genome sequencing means that patients will increasingly face decisions regarding what results they would like to learn. The present study examined psychological and clinical factors that might affect these preferences. 1,080 women diagnosed with breast cancer at age 40 or younger completed an online survey. We assessed their interest in learning various types of genome sequencing results: risk of preventable disease or unpreventable disease, cancer treatment response, uncertain meaning, risk to relatives' health, and ancestry/physical traits. Multivariable logistic regression was used to examine whether being "very" interested in each result type was associated with clinical factors: BRCA1/2 mutation status, prior genetic testing, family history of breast cancer, and psychological factors: cancer recurrence worry, genetic risk worry, future orientation, health information orientation, and genome sequencing knowledge. The proportion of respondents who were very interested in learning each type of result ranged from 16% to 77%. In all multivariable models, those who were very interested in learning a result type had significantly higher knowledge about sequencing benefits, greater genetic risks worry, and stronger health information orientation compared to those with less interest (p-values psychological factors. Shared decision-making approaches that increase knowledge about genome sequencing and incorporate patient preferences for health information and learning about genetic risks may help support patients' informed choices about learning different types of sequencing results. © Society of Behavioral Medicine 2018.

Infant Hand Preference and the Development of Cognitive Abilities

George Frederick Michel

2016-03-01

Full Text Available Hand preference develops in the first two postnatal years with nearly half of infants exhibiting a consistent early preference for acquiring objects. Others exhibit a more variable developmental trajectory but by the end of their second postnatal year, most exhibit a consistent hand preference for role-differentiated bimanual manipulation. According to some forms of embodiment theory, these differences in hand use patterns should influence the way children interact with their environments, which, in turn, should affect the structure and function of brain development. Such early differences in brain development should result in different trajectories of psychological development. We present evidence that children with consistent early hand preferences exhibit advanced patterns of cognitive development as compared to children who develop a hand preference later. Differences in the developmental trajectory of hand preference are predictive of developmental differences in language, object management skills, and tool-use skills. As predicted by Cassasanto’s body-specificity hypothesis, infants with different hand preferences proceed along different developmental pathways of cognitive functioning.

The purpose of this study was to provide further information about preferences for types and formats (e.g., correspondence vs. face to face) of eating and exercise programs, actual participation rates in a variety of offered programs, and characteristics of program participants vs. nonparticipants. Over a 3-year period, a large sample of community volunteers was given the opportunity to participate in various forms of diet and exercise programs as part of a weight gain prevention study. The study was conducted at a university and three local health department sites. Subjects in the study were 616 individuals participating in the Pound of Prevention study (POP), a 3-year randomized evaluation of an intervention for preventing weight gain. The primary outcomes assessed were participation rates for each program offering. Program participants were also compared to those who did not participate on demographic characteristics, smoking, diet behavior, exercise behavior, and weight concern. Survey results indicated that correspondence formats for delivery of health education programs were rated as more desirable than face-to-face formats. Participation for program offering ranged from 0 to 16% of the study population. Participation data were consistent with survey results and showed participants' preference for correspondence formats even more strongly. Program offering attracted health-conscious participants with higher education and income levels. These data suggest that some community members will get interested and take part in low-cost, minimal contact programs for exercise and weight control. Future research efforts should focus on investigating ways to increase participation in brief or minimal contact programs, particularly among groups that may be difficult to reach and at high risk for the development of obesity.

Psammoma body (PB) is a common form of calcification in pathological diagnosis and closely relevant to tumours. This paper focuses on the mineralogical characteristics of PBs in ovarian serous cancer and teratoma by using polarization microscope (POM), environmental scanning electron microscope (ESEM), micro-Fourier transform infrared spectroscopy (micro-FT-IR), transmission electron microscope (TEM), micro-area synchrotron radiation X-ray powder diffraction (μ-SRXRD) and fluorescence (μ-SRXRF). Both the PBs in tissues and separated from eight typical cases were investigated. POM and ESEM observation revealed the inside-out growth pattern of PBs. μ-SRXRD and micro-FT-IR results demonstrated the dominant mineral phase of PBs in ovarian serous cancer and teratoma was AB-type carbonate hydroxyapatite (Ca10[(PO4)6-x-y(CO3)x(HPO4 2-)y][(OH)2-u(CO3)u] with 0 ≤ x,y,u ≤ 2). As observed by ESEM and TEM, the layer-rich PBs in teratoma were up to 70 μm and mainly consisted of 5 nm-wide, 5-12 nm-long columnar crystals; the PBs in ovarian serous cancer with a maximum diameter of 35 μm were composed of slightly longer columnar crystals and granulates with 20-100 nm in diameter. The selected area electron diffraction patterns showed dispersed polycrystalline diffraction rings with arching behavior of (002) diffraction, indicating the aggregated nanocrystals grew in the preferred orientation of (002) face. The EDX and μ-SRXRF results together indicated the existence of Na, Mg, Zn and Sr in PBs. These detailed mineralogical characteristics may help uncover the nature of the pathological PBs in ovary.

Evolutionary psychologists have been interested in male preferences for particular female traits that are thought to signal health and reproductive potential. While the majority of studies have focused on what makes specific body traits attractive-such as the waist-to-hip ratio, the body mass index, and breasts shape and size-there is little empirical research that has examined individual differences in male preferences for specific traits (e.g., favoring breasts over buttocks). The current study begins to fill this empirical gap. In the first experiment (Study 1), 184 male participants were asked to report their preference between breasts and buttocks on a continuous scale. We found that (1) the distribution of preference was bimodal, indicating that Argentinean males tended to define themselves as favoring breasts or buttocks but rarely thinking that these traits contributed equally to their choice and (2) the distribution was biased towards buttocks. In a second experiment (Study 2), 19 male participants were asked to rate pictures of female breasts and buttocks. This study was necessary to generate three categories of pictures with statistically different ratings (high, medium, and low). In a third experiment (Study 3), we recorded eye-movements of 25 male participants while they chose the more attractive between two women, only seeing their breasts and buttock. We found that the first and last fixations were systematically directed towards the self-reported preferred trait.

The scope of healthcare has been expanding from caring for sick people to keeping people from becoming sick, and telemedicine will play a significant role in this new healthcare paradigm. This study investigated consumer preferences and willingness to pay for attributes of telemedicine services in South Korea. A market simulation was conducted to examine the market shares of alternative services and their relationships to the perceived usefulness of service types and preferred device types. Using a conjoint survey, we collected data on consumer preferences for six telemedicine service attributes. Data analysis used the Bayesian mixed logit model. The market simulation estimated the probabilities of a specific service alternative being chosen using estimated model coefficients. Wearable devices were the most preferred, followed by smart-home and smartphone devices. Consumers perceived managing blood glucose to be the most useful telemedicine service, followed by monitoring oxygen saturation and blood pressure. The market simulation indicated that consumer preferences for device types were associated with the types of chronic diseases for which management through telemedicine services is perceived to be useful. As the focus of healthcare moves from treating patients to keeping individuals healthy, a key factor for the successful deployment of telemedicine services is understanding consumer perceptions and attitudes. The results of this study revealed the dynamics of consumer preferences with regard to service attributes.

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 The marine zone tourism is growing attracting more tourists. Pramuka Island is marine conservation area enriched with marine biodiversity in coral reefs and other natural resources. To develop this potential tourist destination, a customer-based marketing program is required to attract domestic and foreign tourists. The main vision is to understand tourist preferences for marine tourism activities and facilities. A research was conducted on Pramuka Island as a well-known marine tourism zone. The objective was to determine the key tourist preferences for marine tourism destination. Research methods utilized Cochran Q test and Conjoint analysis where the primary data were obtained from tourist respondents. The result showed that there was a tourist preference based on the five attributes considered most important, namely tourism activities, tourist attractions, types of accommodation, food and souvenirs types. This study provided marine tourism destination management with useful guidance for broader implications of the implementation of marketing programs and tourism attraction. Moreover, the results of this study consolidated the learning of a variety of academic and industrial research papers in particular for the measurement of customer preferences towards marine tourism destination.

Understanding the whole-body patterns of joint flexibility and their related biological and physical factors contributes not only to clinical assessments but also to the fields of human factors and ergonomics. In this study, ranges of motion (ROMs) at limb and trunk joints of young adults were analysed to understand covariation patterns of different joint motions and to identify factors associated with the variation in ROM. Seventy-eight healthy volunteers (42 males and 36 females) living on Okinawa Island, Japan, were recruited. Passive ROM was measured at multiple joints through the whole body (31 measurements) including the left and right side limbs and trunk. Comparisons between males and females, dominant and non-dominant sides, and antagonistic motions indicated that body structures influence ROMs. In principal component analysis (PCA) on the ROM data, the first principal component (PC1) represented the sex difference and a similar covariation pattern appeared in the analysis within each sex. Multiple regression analysis showed that this component was associated with sex, age, body fat %, iliospinale height, and leg extension strength. The present study identified that there is a spectrum of "masculine" and "feminine" types in the whole-body patterns of joint flexibility. This study also suggested that body proportion and composition, muscle mass and strength, and possibly skeletal structures partly explain such patterns. These results would be important to understand individual variation in susceptibility to joint injuries and diseases and in one's suitable and effective postures and motions.

Aims: To explore the relative value patients place on comfort and convenience versus test sensitivity and specificity in the context of computed tomographic colonography (CTC) screening. Materials and methods: Twenty semi-structured interviews were carried out with patients attending hospital for radiological tests unrelated to CTC. Preferences for CTC with different types of bowel preparation for CTC screening were examined and interviews were analysed thematically. The discussion guide included separate sections on CTC, bowel preparation methods (non-, reduced- and full-laxative), and sensitivity and specificity. Patients were given information on each topic in turn and asked about their views and preferences during each section. Results: Following information about the test, patients' attitudes towards CTC were positive. Following information on bowel preparation, full-laxative purgation was anticipated to cause more adverse physical and lifestyle effects than using reduced- or non-laxative preparation. However, stated preferences were approximately equally divided, largely due to patients anticipating that non-laxative preparations would reduce test accuracy (because the bowel was not thoroughly cleansed). Following information on sensitivity and specificity (which supported patients' expectations), the predominant stated preference was for full-laxative preparation. Conclusions: Patients are likely to value test sensitivity and specificity over a more comfortable and convenient preparation. Future research should test this hypothesis on a larger sample

Full Text Available This study intended to investigate the interaction developing rapidly through the impact of globalization experienced in every field on the material and size preferences of the kitchen furniture sector. The results of the survey conducted on the Turkish kitchen furniture manufacturers were evaluated within the framework of the international kitchen trends. As a result it was seen that the most preferred kitchen area was between 8 and 11 m2 regarding the distribution of the kitchen areas in Turkey. A tendency of using MDF in the production of the kitchen cabinets was observed with 61.8% in relation with the body material preferred to be used in the kitchen furniture sector. The preferred body sizes of the kitchen cabinet was determined by considering the width and height preferences of both the upper and lower cabinets, the size of 61-90 cm seemed to be the most preferred sizes both for the upper and lower cabinets. According to the height, 72 cm size was found to be the most preferred size. While the most preferred size among the cellar cabinets was determined to be smaller than 60 cm, its height was revealed to be bigger than 200 cm. The most preferred kitchen furniture base was detected to be 12 cm.

Segmenting consumers according to experiential preferences based on personality type vs. personality traits – a latent class analysis

DEFF Research Database (Denmark)

Sørensen, Jeanne

Differences in consumers’ preferences for experiences have been suggested to be based on personality among other things. Personality in consumer research has primarily been operationalized as personality traits using the Five Factor theory. An old, re-emerged discussion in psychology is pointing...... at personality type rather than single personality traits to better understand behavior. Personality type represents “typical configurations of the dispositional attributes that define individuals” (Donnellan and Robins, 2010: 1). Type accounts for the necessity of understanding not only a person’s defining...... trait but also how this interacts with other traits providing a person centered rather than an attribute centered understanding. This allows for a classification of people rather than a classification of attributes of people. In the context of segmentation the objective is classifying people rather than...

Hedenec, Petr; Frouz, Jan

2016-04-01

Soil fungi are important food resources for soil fauna. Here we ask whether the collembolan Folsomia candida shows selectivity in grazing between four saprophytic fungi (Penicillium chrysogenum, Penicillium expansum, Absidia glauca, and Cladosporium herbarum), whether grazing preference corresponds to effects on collembolan reproduction, and whether the effects of fungi on grazing and reproduction depends on the fungal substrate, which included three kinds of litter (Alnus glutinosa, Salix caprea, and Quercus robur) and one kind of agar (yeast extract). On agar, Cladosporium herbarum and Absidia glauca were the most preferred fungi and supported the highest collembolan reproduction. On fungal-colonized litter, grazing preference was more affected by litter type than by fungal species whereas collembolan reproduction was affected by both litter type and fungal species. On fungal-colonized litter, the litter type that was most preferred for grazing did not support the highest reproduction, i.e., there was an inconsistency between food preference and suitability. Alder and willow were preferred over oak for grazing, but alder supported the least reproduction.

The preference and actual use of different types of rural recreation areas by urban dwellers--the Hamburg case study.

Directory of Open Access Journals (Sweden)

Thiemen Boll

Full Text Available In the wake of urbanisation processes and the constitution of metropolitan regions, the role of the city's rural surroundings is receiving more attention from researchers and planners as rural areas offer various (cultural ecosystem services for the urban population. Urban dwellers increasingly desire recreation and landscape experience. Although this need for recreation is generally recognized, few studies have focused on the question of people's preferences for certain types and characteristics of outdoor recreation areas in relation to the frequency of use. In order to acquire baseline data on this subject, the main objectives of this study were to explore recreation preferences of urban dwellers and the relation between actual use and perceived value of recreation areas in a case study in the Hamburg Metropolitan Region (Germany. In a social survey, Hamburg residents (n = 400 were asked about their preferences and use of four important regional recreation areas with different landscape characteristics in face-to-face interviews in different locations in the city. We found that both outdoor recreation within and outside of the city were fairly or very important for more than 70% of the questioned urban dwellers. Interestingly, the preference for a recreation area outside of the city did not depend on the frequency of use, which indicates that certain recreation areas had a symbolic value besides their use value. When people were questioned on the characteristics of recreation areas, perceived naturalness was found to be strongly related to preference. Respondents considered the diversity, uniqueness, and naturalness of the landscape to be far more important than the accessibility of the recreation areas and the provision of service facilities.

Another New Solvable Many-Body Model of Goldfish Type

Francesco Calogero

2012-07-01

Full Text Available A new solvable many-body problem is identified. It is characterized by nonlinear Newtonian equations of motion (''acceleration equal force'' featuring one-body and two-body velocity-dependent forces ''of goldfish type'' which determine the motion ofan arbitrary number $N$ of unit-mass point-particles in a plane. The $N$ (generally complex values $z_{n}(t$ at time $t$ ofthe $N$ coordinates of these moving particles are given by the $N$eigenvalues of a time-dependent $Nimes N$ matrix $U(t$explicitly known in terms of the $2N$ initial data $z_{n}(0$and $dot{z}_{n}(0 $. This model comes in two dif/ferentvariants, one featuring 3 arbitrary coupling constants, the other only 2; for special values of these parameters all solutions are completely periodic with the same period independent of the initial data (''isochrony''; for other special values of these parameters this property holds up to corrections vanishing exponentially as $tightarrow infty$ (''asymptotic isochrony''. Other isochronous variants of these models are also reported. Alternative formulations, obtained by changing the dependent variables from the $N$ zeros of a monic polynomial of degree $N$ to its $N$ coefficients, are also exhibited. Some mathematical findings implied by some of these results - such as Diophantine properties of the zeros of certain polynomials - are outlined, but their analysis is postponed to a separate paper.

Advertising Challenges in the Ageing Society: The Preferences of the Regular Gym-goers towards Age Portrayals in Advertising

Full Text Available Research studies from various disciplines including sociology, psychology, social psychology, marketing, advertising and media research have analyzed the representation of old-aged people in advertising, as well as the consumers’ habits of a targeted population aged 50 and over. Despite the availability of data on inappropriate depiction of seniors in media (including advertising, little research has been done so far to understand which are the seniors’ preferences regarding their portrayal in certain advertising campaigns. The aim of the current study was to explore the preferences of middle-aged adults toward the representation of old age in advertising. Specifically, we tested whether there is a relationship between the preferences of Romanians gym-goers (45-60 years on age-related advertising and their body image. The results showed that the middle-aged adults prefer models that do not necessary match their age, that is the young older model. Our data also revealed that the choices for age representations in advertising were not associated with respondents’ body image emotions in certain contexts or situations. No significant relationship between body image and preference towards age-related representations in advertising was obtained. Additionally, the analysis of the data also revealed that compared to men, women are more likely to express displeasure with their body weights, and they believe the body image strongly impacts their self-esteem during life.

Why do the Karo Batak prefer women with big feet? Flexible mate preferences and the notion that one size fits all.

Science.gov (United States)

Kushnick, Geoff

2013-09-01

Men may find women with small feet relative to body size more attractive because foot size reliably indexes nubility-i.e., age and parity. I collected judgments of attractiveness in response to drawings of women with varying foot sizes from a sample of 159 Karo Batak respondents from North Sumatra, Indonesia, as part of a collaborative project on foot size and attractiveness. The data revealed a contrarian preference among the Karo Batak for women with big feet. The judgments were compared with the results of an existing cross-cultural study that found a preference for women with small feet in aggregate, but a mix of small- and large-foot preferences in the societies taken individually. Using contingency table analysis, I found that ecology and less exposure to Western media were associated with a preference for women with big feet; patriarchal values were not. The findings suggest that human mating preferences may arise in response to local ecological conditions, and may persist and spread via cultural transmission. This has implications for the concept of universality espoused in some versions of evolutionary psychology.

Physicians' attire is one important factor to enhance the physician-patient relationship. However, there are few studies that examine patients' preferences for physicians' attire in Japan. We sought to assess patients' preference regarding doctors' attire and to assess the influence of doctors' attire on patients' confidence in their physician. Furthermore, we examined whether patients' preferences would change among various clinical situations. Employing a cross-sectional design, Japanese outpatients chosen over one week in October 2008 from waiting rooms in various outpatient departments at St. Luke's International Hospital, Tokyo, were given a 10-item questionnaire. A 5-point Likert scale was used to estimate patient preference for four types of attire in both male and female physicians, including semi-formal attire, white coat, surgical scrubs, and casual wear. In addition, a 4-point Likert Scale was used to measure the influence of doctors' attire on patient confidence. Japanese outpatients consecutively chosen from waiting rooms at St. Luke's International Hospital in Tokyo for one week in October 2008. Of 2,272 outpatients enrolled, 1483 (67.1%) of respondents were women. Mean age of subjects was 53.8 years (SD 16.2 years). Respondents most preferred the white coat (mean rank: 4.18, SD: 0.75) and preferred casual attire the least (mean rank: 2.32, SD: 0.81). For female physicians, 1.4% of respondents ranked the white coat little/least preferred while 64.7% of respondents ranked casual wear little/least preferred. Among respondents who most preferred the white coat for physician attire, perceived hygiene (62.7%) and inspiring confidence (59.3%) were important factors for doctor's attire. Around 70% of all respondents reported that physicians' attire has an influence on their confidence in their physician. This study confirms that Japanese outpatients prefer a white coat. Furthermore, this study strongly suggests that wearing a white coat could favorably

An Intra-Group Perspective on Leader Preferences

DEFF Research Database (Denmark)

Bøggild, Troels; Laustsen, Lasse

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...

The aim of the study was to evaluate the influence of age and gender on the prevalence of overweight and obesity, body composition and fatty tissue distribution in young adults with type 1 diabetes. 197 patients with type 1 diabetes aged 20-40 years participated in the study. The control group consisted of 138 healthy adults. Body weight, height, waist and hip circumferences were measured. Analysis of body mass composition was performed using the bioimpedance. Study groups were stratified into cohorts aged obesity were diagnosed in 35.5% and 13.2% of diabetic patients and in 26.1% and 7.3% of the control group, respectively (p=0.016). In the whole study group, advanced age (OR=1.10; pobesity, but a trend toward excessive body mass was observed in diabetic females (OR=1.18; p=0.181). Diabetic females more often had abdominal obesity than control females (mean difference - 19.2%; p=0.020). Higher total body fat mass was found in the diabetic group (p=0.037). Diabetic females had a higher amount of absolute (pobesity in early adulthood more frequently than the general population and are characterized by higher body fat mass. Gender-related differences in body weight and composition in young type 1 diabetic adults were found.

Full Text Available Background: Understanding preferences for information provision in the context of health care service provision is challenging because of the number of potential attributes that may influence preferences. This study aimed to identify midwives’ preferences for the process and outcomes of information provision in an expanded national newborn bloodspot screening program. Design: A sample of practicing midwives completed a hybrid-stated preference survey including a conjoint analysis (CA and discrete choice experiment to quantify preferences for the types of, and way in which, information should be provided in a newborn bloodspot screening program. Six conjoint analysis questions captured the impact of different types of information on parents’ ability to make a decision, and 10 discrete choice experiment questions identified preferences for four process attributes (including parents’ ability to make a decision. Results: Midwives employed by the UK National Health Service (n = 134 completed the survey. All types of information content were perceived to improve parents’ ability to make a decision except for the possibility of false-positive results. Late pregnancy was seen to be the best time to provide information, followed by day 3 postbirth. Information before 20 weeks of pregnancy was viewed as reducing parents’ ability to make a decision. Midwives preferred information to be provided by an individual discussion and did not think parents should receive information on the Internet. Conclusion: A hybrid stated preference survey design identified that a wide variety of information should be provided to maximize parents’ ability to make a decision ideally provided late in pregnancy or on day 3 postbirth.

Analyses of brain tissue in a recently identified group of elderly demented patients suggest a neurochemical basis for some of the clinical features. Senile dementia of the Lewy body type (SDLT) can be distinguished from classical Alzheimer disease (AD) clinically by its acute presentation with confusion frequently accompanied by visual hallucinations, and neuropathologically by the presence of Lewy bodies and senile plaques (but not generally neurofibrillary tangles) in the cerebral cortex. Reductions in the cortical cholinergic enzyme choline acetyltransferase were more pronounced in individuals with (80%) compared to those without (50%) hallucinations and correlated strongly with mental test scores in the group as a whole. In the caudate nucleus, dopamine levels were related to the number of neurons in the substantia nigra, there being a 40-60% loss of both in SDLT--probably accounting for mild extrapyramidal features in some of these cases--compared with an 80% loss in Parkinson disease and no change in AD. The cholinergic correlates of mental impairment in SDLT together with the relative absence of cortical neurofibrillary tangles and evidence for postsynaptic cholinergic receptor compensation raise the question of whether this type of dementia may be more amenable to cholinotherapy than classical AD.

The purpose of this study was to identify individual musical preferences, investigate the relationship between an individual's musical preferences and demographic variables, and examine the effects of the selected music on relaxation. Fifty healthy subjects (mean age 65.7; SD = 5.2) from the community participated in the study. Musical preference interviews and relaxed responses to selected music were administered to the study participants individually in the investigator's office. Participants' heart rates, respiratory rates, and finger temperature were measured before they listened to the introductory tape and again after they listened to the selected music for 20 minutes. The participants were asked to judge how much they liked the 6 types of soothing music and were asked to rate it on a scale. The results indicated that Chinese orchestral music was the preferred choice, followed by harp, piano, synthesizer, orchestral, and finally slow jazz. There were no differences among types of music on relaxation, and no significant differences between musical preference and any demographic variables. The heart rates and respiratory rates of the participants were significantly lower (t = 21.24, P music. These findings suggest that soothing music selections have beneficial effects on relaxation in community-residing elderly people.

To gain an in-depth understanding of the fineness and regulation mechanism of body color mutant of Helicoverpa armigera Hbner, the protein composition differences between adult of dominant mutant, recessive mutant and wild type were studied using the SDS-PAGE combined with MALDI-TOF-TOF/MS and bioinformatics analysis. The results indicated that the protein composition of the dominant mutant and wild type had little difference. However, there were obvious differences between the recessive mutant and wild-type. Three specific stripe were chosen for mass spectrometry and bioinformatics analysis, and two types of proteins related to energy metabolism and cytoskeleton were identified. These findings suggested that the two types of proteins may be associated with occurrence and regulation of body color mutant traits of H. armigera. (authors)

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

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.

Prey preferences of the jaguar Panthera onca reflect the post-Pleistocene demise of large prey.

Full Text Available Documenting the impacts of the Pleistocene megafaunal extinctions on predator-prey interactions is a challenge because of the incomplete fossil record and depauperate extant community structure. We used a comparative ecological approach to investigate whether the existing prey preference patterns of jaguars Panthera onca were potentially affected by the Pleistocene extinctions in the Americas compared with large felids in Africa and Asia. We reviewed the literature and found 25 studies reporting 3214 jaguar kills recorded throughout the species’ distribution. We found that jaguars significantly preferred capybara Hydrochaeris hydrochaeris and giant anteater Myrmecophaga tridactyla, and avoided agoutis, carnivorans, primates, black-eared opossum Didelphis marsupialis and tapirs. Generalised linear models showed that jaguars select prey primarily based on socio-ecological and behavioural traits (abundance and herd size, rather than morphological characteristics (body size. Nonetheless, their accessible prey weight range was 6-60 kg, preferred prey weight range was 45-85 kg, and mean mass of significantly preferred prey was 32 ± 13 kg leading to a predator to prey body mass ratio of 1:0.53, which is much less than that of other solitary felids. Compared with other large, solitary felids, jaguars have an unusual predator to prey body mass ratio, show limited effect of prey morphology as a driver of prey selection, lack evidence of optimal foraging beyond their preferred prey, and an absence of preferentially hunting on Cetartiodactyla herbivores. These features, coupled with the reduction in jaguar body mass since the Pleistocene, suggest that the loss of larger potential prey items within the preferred and accessible weight ranges at the end-Pleistocene still affects jaguar predatory behaviour. It may be that jaguars survived this mass extinction event by preferentially preying on relatively small species.

Vacuolar ATPase regulates surfactant secretion in rat alveolar type II cells by modulating lamellar body calcium.

Full Text Available Lung surfactant reduces surface tension and maintains the stability of alveoli. How surfactant is released from alveolar epithelial type II cells is not fully understood. Vacuolar ATPase (V-ATPase is the enzyme responsible for pumping H(+ into lamellar bodies and is required for the processing of surfactant proteins and the packaging of surfactant lipids. However, its role in lung surfactant secretion is unknown. Proteomic analysis revealed that vacuolar ATPase (V-ATPase dominated the alveolar type II cell lipid raft proteome. Western blotting confirmed the association of V-ATPase a1 and B1/2 subunits with lipid rafts and their enrichment in lamellar bodies. The dissipation of lamellar body pH gradient by Bafilomycin A1 (Baf A1, an inhibitor of V-ATPase, increased surfactant secretion. Baf A1-stimulated secretion was blocked by the intracellular Ca(2+ chelator, BAPTA-AM, the protein kinase C (PKC inhibitor, staurosporine, and the Ca(2+/calmodulin-dependent protein kinase II (CaMKII, KN-62. Baf A1 induced Ca(2+ release from isolated lamellar bodies. Thapsigargin reduced the Baf A1-induced secretion, indicating cross-talk between lamellar body and endoplasmic reticulum Ca(2+ pools. Stimulation of type II cells with surfactant secretagogues dissipated the pH gradient across lamellar bodies and disassembled the V-ATPase complex, indicating the physiological relevance of the V-ATPase-mediated surfactant secretion. Finally, silencing of V-ATPase a1 and B2 subunits decreased stimulated surfactant secretion, indicating that these subunits were crucial for surfactant secretion. We conclude that V-ATPase regulates surfactant secretion via an increased Ca(2+ mobilization from lamellar bodies and endoplasmic reticulum, and the activation of PKC and CaMKII. Our finding revealed a previously unrealized role of V-ATPase in surfactant secretion.

Changes in the structure and functioning of the body occur with age. Also nutrition is continually modified. Eating habits may affect favorably or unfavorably on the process of aging and the functioning of various tissues, organs and the whole body. The purpose of the study was to evaluate dietary habits and food preferences of patients in different age groups. In the studied groups also body mass index (BMI) and body fat content were analyzed. 237 people (133 women and 104 men, age 18-79 years) were examined. The participants completed questionnaires of the frequency of food consumption and food preferences. The height, weight, body mass index (BMI), the percentage of body fat (BIA) were also measured. For statistical analysis the assessment of correlation Spearman's rank order and nonparametric ANOVA rank Kruskal-Wallis were used. With age, the frequency of milk (p habits vary depending on age and may be one of the elements affecting the increase in BMI, body fat content, bone mass loss and increased risk of metabolic disorders. The observed changes in dietary habits can contribute to the development of dyslipidemia, glucose dysmetabolism and arterial hypertension, especially in the presence of overweight and obesity.

"Casual sex" is seldom as non-selective and random as it may sound. During each sexual encounter, people consciously and unconsciously seek their casual sex partners according to different attributes. Influential to a sexual network, research focusing on quantifying the effects of physical appearance on sexual network has been sparse. We evaluated the application of Log odds score (LOD) to assess the mixing patterns of 326 men who have sex with men (MSM) in Hong Kong in their networking of casual sex partners by Body Image Type (BIT). This involved an analysis of 1,196 respondents-casual sex partner pairs. Seven BITs were used in the study: Bear, Chubby, Slender, Lean toned, Muscular, Average and Other. A hierarchical pattern was observed in the preference of MSM for casual sex partners by the latter's BIT. Overall, Muscular men were most preferred, followed by Lean toned while the least preferred was Slender, as illustrated by LOD going down along the hierarchy in the same direction. Marked avoidance was found between men who self-identified as Chubby and men of Other body type (within-group-LOD: 1.25-2.89; between-group-LOD: man who self-identified as Average for casual sex. We have demonstrated the possibility of adopting a mathematical prototype to investigate the influence of BIT in a sexual network of MSM. Construction of matrix based on culture-specific BIT and cross-cultural comparisons would generate new knowledge on the mixing behaviors of MSM.

Do assortative preferences contribute to assortative mating for adiposity?

2014-01-01

Assortative mating for adiposity, whereby levels of adiposity in romantic partners tend to be positively correlated, has implications for population health due to the combined effects of partners' levels of adiposity on fertility and/or offspring health. Although assortative preferences for cues of adiposity, whereby leaner people are inherently more attracted to leaner individuals, have been proposed as a factor in assortative mating for adiposity, there have been no direct tests of this issue. Because of this, and because of recent work suggesting that facial cues of adiposity convey information about others' health that may be particularly important for mate preferences, we tested the contribution of assortative preferences for facial cues of adiposity to assortative mating for adiposity (assessed from body mass index, BMI) in a sample of romantic couples. Romantic partners' BMIs were positively correlated and this correlation was not due to the effects of age or relationship duration. However, although men and women with leaner partners showed stronger preferences for cues of low levels of adiposity, controlling for these preferences did not weaken the correlation between partners' BMIs. Indeed, own BMI and preferences were uncorrelated. These results suggest that assortative preferences for facial cues of adiposity contribute little (if at all) to assortative mating for adiposity.

2014-03-01

Despite much research on machine translation (MT) evaluation, there is surprisingly little work that directly measures users' intuitive or emotional preferences regarding different types of MT errors. However, the elicitation and modeling of user preferences is an important prerequisite for research on user adaptation and customization of MT engines. In this paper we explore the use of conjoint analysis as a formal quantitative framework to assess users' relative preferences for different types of translation errors. We apply our approach to the analysis of MT output from translating public health documents from English into Spanish. Our results indicate that word order errors are clearly the most dispreferred error type, followed by word sense, morphological, and function word errors. The conjoint analysis-based model is able to predict user preferences more accurately than a baseline model that chooses the translation with the fewest errors overall. Additionally we analyze the effect of using a crowd-sourced respondent population versus a sample of domain experts and observe that main preference effects are remarkably stable across the two samples.

Full Text Available Objective. Albuminuria in type 2 diabetes mellitus (T2DM patients increases the risk of diabetic nephropathy, the leading cause of end-stage renal disease worldwide. Because albuminuria is modifiable, identifying relevant risk factors could facilitate prevention and/or management. This cross-sectional study investigated whether body constitution (BC independently predicts albuminuria. Method. Patients with T2DM (n=846 received urinalysis, a blood test, and diabetic retinopathy examination. Albuminuria was defined by an elevated urinary albumin/creatinine ratio (≥30 μg/mg. BC type (Yang deficiency, Yin deficiency, and Phlegm stasis was assessed using a body constitution questionnaire (BCQ. Traditional risk factors for albuminuria were also recorded. Odds ratios (ORs of albuminuria for BC were estimated using multivariate logistic regression. Results. Albuminuria was more prevalent in patients with Yang deficiency or Phlegm stasis (both P<0.01. After adjustment, patients with both Yang deficiency and Phlegm stasis exhibited a significantly higher risk of albuminuria (OR = 3.037; 95% confidence interval = 1.572–5.867, and P<0.001. Conclusion. BC is strongly associated with albuminuria in T2DM patients. Using a BCQ to assess BC is noninvasive, convenient, and inexpensive and can provide information for health care professionals to identify T2DM patients who are at a high risk of albuminuria.

Recent reports have suggested that brain stem and cortical Lewy body formation may identify a neurodegenerative disorder in elderly demented individuals which accounts for up to 20% of cases of senile dementia coming to autopsy. Retrospective analysis of case notes of 21 autopsy patients with neuropathologically proven senile dementia of Lewy body type (SDLT) and 37 cases with neuropathologically proven Alzheimer's disease (AD) identified a characteristic clinical syndrome in SDLT. Fluctuating cognitive impairment; psychotic features including visual and auditory hallucinations, and paranoid delusions; depressive symptoms; falling and unexplained losses of consciousness were all seen significantly more often than in AD. Over half of the SDLT patients in this series who were given neuroleptics in standard dose showed acute and often irreversible adverse reactions indicative of a neuroleptic sensitivity syndrome. The survival time of drug treated patients was reduced by 50%. Operational criteria to aid in the clinical distinction between SDLT and AD patients are proposed and hypotheses regarding possible aetiology and treatment discussed.

Students’ Media Preferences in Online Learning

2017-07-01

Full Text Available This study examined students’ preferred media in online learning and its relationship with learner characteristics and online technology self-efficacy. One hundred six college students in a mid-size U.S. university responded to a survey. The frequency analysis showed that students did not necessarily favor rich media over lean media in online learning. They preferred recorded online slide presentations with audio to Internet-based live video lectures in two-way video and audio interactions. Online discussion boards and chat groups were less favored than other types of media. As expected, online technology self-efficacy was correlated with a type of media requiring a relatively higher level of technology skills. The paper presents the results and discusses their implications of the study.

A growing body of work suggests that early motor experience affects development in unexpected domains. In the current study, children's hand preference for role-differentiated bimanual manipulation (RDBM) was measured at monthly intervals from 18 to 24 months of age (N = 90). At 3 years of age, children's language ability was assessed using the Preschool Language Scales 5th edition (PLS™-5). Three distinct RDBM hand preference trajectories were identified using latent class growth analysis: (1) children with a left hand preference but a moderate amount of right hand use; (2) children with a right hand preference but a moderate amount of left hand use; and (3) children with a right hand preference and only a mild amount of left hand use. Stability over time within all three trajectories indicated that children did not change hand use patterns from 18 to 24 months. Children with the greatest amount of preferred (i.e., right) hand use demonstrated higher expressive language scores compared to children in both trajectories with moderate levels of non-preferred hand use. Children with the greatest amount of right hand use also had higher scores for receptive language compared to children with a right hand preference but moderate left hand use. Results support that consistency in handedness as measured by the amount of preferred hand use is related to distal language outcomes in development. © 2017 Wiley Periodicals, Inc.

Lighting preferences in individual offices

João Roberto Gomes de Faria

Full Text Available Abstract Workplaces with good daylighting offer visual comfort to users, give them a series of physiological and psychological benefits and allow good performance of visual activities, besides saving energy. However, this solution is not always adopted: lighting type preferences involve many variables besides the availability of daylight. This paper explores a case study through the analysis of questionnaire answers and computer simulations of a series of metrics related to quality of lighting with the aim of finding explanations for the lighting preferences of individual office users. The results show that, although the offices present good daylighting conditions and no glare potential, and users are satisfied with daylighting, these parameters are not sufficient to explain the predominant lighting preferences. The findings have also shown that there is no consensus about which parameters potentially cause visual comfort, while the parameters that cause discomfort are clearly identified. In addition, in this study, 49% of the preference for mixed lighting (daylight plus electrical light can be explained by the fact that mixed lighting produces better modeling than daylighting alone.

Full Text Available This study aimed at verifying the presence of variations in the reactions of different types of audiences to certain communication tools for wine. Five samples of audiences were compared: wine professionals, organic produce specialists, wine tourists, and two samples of general tourists. The following bundle of attributes were considered: name of the grape; information on organic production methods; type of closure; QR code; landscape; advertising language. Diverse audience’s preferences were measured by conjoint analysis. The results have shown a common sensitivity to certain attributes, and a different or contrary sensitivity to others. In particular, all samples have demonstrated that: 1 certified organic wines communicated in standard wine-market style have the potential of becoming market leaders; 2 photographs facilitate the acceptance of technologically-advanced closures; 3 the presence of the QR code in printed advertisements increases the expected value of the product; 4a landscape characterised by holistic “garden viticulture” increases preferences. Textual language was more effective with professionals, while photographic language was more effective with tourists. Supplementary information on the organic production methods, in addition to the mandatory labelling requirements, increased the preferences of professionals and wine tourists, and was counterproductive with the general tourists.

As a prerequisite for active involvement, patients need to be informed in an adequate and preference-sensitive way. Interactive Health Communication Applications (IHCAs that combine web-based health information for patients with additional support offer the opportunity to reach great numbers of patients at low cost and provide them with high-quality information and support at the time, place, and learning speed they prefer. Still, web-based interventions often suffer from high attrition. Tailoring the intervention to patients’ needs and preferences might reduce attrition and should thereby increase effectiveness. The purpose of this study was to develop a tailored IHCA offering evidence-based, preference-sensitive content and treatment decision support to patients with type 2 diabetes. The content was developed based on a needs assessment and two evidence-based treatment guidelines. The delivery format is a dialogue-based, tunneled design tailoring the content and tone of the dialogue to relevant patient characteristics (health literacy, attitudes toward self-care, and psychological barriers to insulin treatment. Both content and tailoring were revised by an interdisciplinary advisory committee.Conclusion: The World Wide Web holds great potential for patient information and self-management interventions. With the development and evaluation of a tailored IHCA, we complement face-to-face consultations of patients with their health care practitioners and make them more efficient and satisfying for both sides.

Canagliflozin, a sodium glucose co-transporter 2 (SGLT2) inhibitor, has been associated with weight loss in a broad range of patients with type 2 diabetes mellitus (T2DM). This analysis further evaluated changes in body weight and composition with canagliflozin in two 104-week, Phase 3 studies. In Study 1, patients aged 18-80 years (N = 1,450) received canagliflozin 100 or 300 mg or glimepiride as add-on to metformin for a 52-week core treatment period, followed by a 52-week extension period. In Study 2, patients aged 55-80 years (N = 714) received canagliflozin 100 or 300 mg or placebo added to stable background antihyperglycemic agents for a 26-week core treatment period, followed by a 78-week extension period. Percent change from baseline in body weight; proportion of patients with any weight loss, ≥5% weight loss, and ≥10% weight loss; change in body mass index (BMI) and waist circumference; change in body weight across weight-loss quartiles; and changes in body composition were evaluated in both studies. Canagliflozin 100 and 300 mg provided sustained weight loss versus either glimepiride or placebo over 104 weeks. More patients experienced any weight loss and ≥5% weight loss with canagliflozin versus comparator. Across the 3 highest weight-loss quartiles, canagliflozin provided greater weight loss versus glimepiride or placebo. BMI and waist circumference reductions were observed with canagliflozin 100 and 300 mg versus either glimepiride or placebo over 104 weeks; more patients had BMI or waist circumference reductions with canagliflozin versus comparator. Body composition analysis indicated that the majority of weight loss was due to loss of fat mass. Canagliflozin was generally well tolerated, with increased incidence of adverse events related to the SGLT2 inhibition mechanism. Canagliflozin 100 and 300 mg provided sustained reductions in body weight, BMI, and waist circumference in a greater proportion of patients with T2DM versus

Full Text Available Abstract Background Body mass index (BMI is often used as an objective surrogate estimate of body fat. Increased BMI is directly associated with an increase in metabolic disease, such as type 2 diabetes mellitus (T2DM. The Stunkard Figure Rating Scale (FRS is a subjective measure of body fat, and self-perceptions of body image conceivably impact the development and treatment of T2DM. This study examined the self-perception of body image to various levels of BMI among those with T2DM. Methods Respondents (n = 13,887 to the US Study to Help Improve Early evaluation and management of risk factors Leading to Diabetes (SHIELD 2006 survey self-reported their weight and height for BMI calculation. On the gender-specific Stunkard FRS, respondents selected the figure most closely resembling their body image. Spearman correlation was computed between perceived body image and BMI for men and women separately. Student's t-test analysis compared the mean BMI differences between respondents with and without T2DM. Results Men with T2DM did not significantly differ from men without diabetes mellitus in mean BMI per body image figure except at the extremes in body figures. Women with T2DM had a significantly higher BMI for the same body figure compared with women without diabetes mellitus for most figures (p Conclusions Individuals, particularly women, with T2DM may differ in their perception of body image compared with those without diabetes mellitus. It is unclear if these perceived differences increase the risk of T2DM, or if the diagnosis of T2DM alters body image perceptions.

Full Text Available This study aimed on revealing students’ preference on types of corrective feedback given by their English teacher as well as their reason. The study was conducted in a vocational school in Samarinda. Data collection was done by means of observation, interview and questionnaire. The observation was done for three meetings each in two different level of English proficiency classes (high and low and ten students from the observed classes were interviewed. Moreover, the questionnaires were administered to 196 out of 385 students from all classes of twelfth grade. Furthermore, the result of this study revealed that the students preferred to have Explicit, Meta-Linguistic Clue and Elicitation corrective feedback. However, there was mismatch between students’ preference on the expected type corrective feedback (Explicit and the teacher’s corrective feedback (Recast. The students’ preference on explicit corrective feedback was based on the reason that it provided answer and explanation on the correct version of the corrected oral production. The students’ preference on Meta-linguistic Clue and Elicitation corrective feedback were because these feedbacks activated their knowledge and generated students’ thinking to discover the correct version.

Preference Learning and Ranking by Pairwise Comparison

Science.gov (United States)

Fürnkranz, Johannes; Hüllermeier, Eyke

This chapter provides an overview of recent work on preference learning and ranking via pairwise classification. The learning by pairwise comparison (LPC) paradigm is the natural machine learning counterpart to the relational approach to preference modeling and decision making. From a machine learning point of view, LPC is especially appealing as it decomposes a possibly complex prediction problem into a certain number of learning problems of the simplest type, namely binary classification. We explain how to approach different preference learning problems, such as label and instance ranking, within the framework of LPC. We primarily focus on methodological aspects, but also address theoretical questions as well as algorithmic and complexity issues.

There is limited information on the association between metabolic syndrome components including body mass index (BMI) and type 2 diabetes mellitus in elderly Chinese population. Therefore, we investigated whether components of metabolic syndrome are associated with type 2 diabetes mellitus in elderly. A total of 479 hospitalized patients (aged 65-95 years) with recently diagnosed type 2 diabetes mellitus were studied retrospectively in a cross-sectional study and compared with 183 subjects with prediabetes and 62 subjects without glucose metabolism abnormalities. BMI (24.69±3.59 versus 23.92±3.08 and 23.56±3.25 kg/m 2 ), blood pressure, cholesterol, triglyceride, liver enzymes and prevalence of fatty liver were higher in patients with type 2 diabetes mellitus as compared with elderly subjects with prediabetes or normal glucose metabolism separately (all P type 2 diabetes mellitus group (all P type 2 diabetes mellitus.

What women like: influence of motion and form on esthetic body perception

Full Text Available Several studies have shown the distinct contribution of motion and form to the esthetic evaluation of female bodies. Here, we investigated how variations of implied motion and body size interact in the esthetic evaluation of female and male bodies in a sample of young healthy women. Participants provided attractiveness, beauty, and liking ratings for the shape and posture of virtual renderings of human bodies with variable body size and implied motion. The esthetic judgments for both shape and posture of human models were influenced by body size and implied motion, with a preference for thinner and more dynamic stimuli. Implied motion, however, attenuated the impact of extreme body size on the esthetic evaluation of body postures, and body size variations did not affect the preference for more dynamic stimuli. Results show that body form and action cues interact in esthetic perception, but the final esthetic appreciation of human bodies is predicted by a mixture of perceptual and affective evaluative components.

2010-02-01

Full Text Available Abstract Background This study aimed to canvass the nature of adolescent-parent interactions about weight, particularly overweight, and to explore ideas of how to foster supportive discussions regarding weight, both in the home and with family doctors. Methods A market research company was contracted to recruit and conduct a series of separate focus groups with adolescents and unrelated parents of adolescents from low-middle socio-economic areas in Sydney and a regional centre, Australia. Group discussions were audio recorded, transcribed, and then a qualitative content analysis of the data was performed. Results Nine focus groups were conducted; two were held with girls (n = 13, three with boys (n = 18, and four with parents (20 mothers, 12 fathers. Adolescent and parent descriptions of weight-related interactions could be classified into three distinct approaches: indirect/cautious (i.e. focus on eating or physical activity behaviors without discussing weight specifically; direct/open (i.e. body weight was discussed; and never/rarely discussing the subject. Indirect approaches were described most frequently by both adolescents and parents and were generally preferred over direct approaches. Parents and adolescents were circumspect but generally supportive of the potential role for family doctors to monitor and discuss adolescent weight status. Conclusions These findings have implications for developing acceptable messages for adolescent and family overweight prevention and treatment interventions.

NiAs-type manganese telluride (MnTe) films with preferred crystallographic plane of (110) were prepared on Si/SiO{sub 2} substrates by pulsed laser deposition. X-ray diffraction (XRD) of the films was studied at different temperatures. The XRD peak of MnTe (110) films shifts to higher angle with decreasing temperature, showing the decrease of the lattice parameter. Resistivity of the films was studied in the temperature range of 2–350 K. The bump between 150 and 250 K was observed in the films, which may be related to the special s-d and p-d overlaps induced by the compressed lattice. The magnon drag effect near its Néel temperature T{sub N} and enlarged magnetic-elastic coupling below 100 K were observed and analyzed in details.

Full Text Available "Casual sex" is seldom as non-selective and random as it may sound. During each sexual encounter, people consciously and unconsciously seek their casual sex partners according to different attributes. Influential to a sexual network, research focusing on quantifying the effects of physical appearance on sexual network has been sparse.We evaluated the application of Log odds score (LOD to assess the mixing patterns of 326 men who have sex with men (MSM in Hong Kong in their networking of casual sex partners by Body Image Type (BIT. This involved an analysis of 1,196 respondents-casual sex partner pairs. Seven BITs were used in the study: Bear, Chubby, Slender, Lean toned, Muscular, Average and Other.A hierarchical pattern was observed in the preference of MSM for casual sex partners by the latter's BIT. Overall, Muscular men were most preferred, followed by Lean toned while the least preferred was Slender, as illustrated by LOD going down along the hierarchy in the same direction. Marked avoidance was found between men who self-identified as Chubby and men of Other body type (within-group-LOD: 1.25-2.89; between-group-LOD: <-1. None of the respondents reported to have networked a man who self-identified as Average for casual sex.We have demonstrated the possibility of adopting a mathematical prototype to investigate the influence of BIT in a sexual network of MSM. Construction of matrix based on culture-specific BIT and cross-cultural comparisons would generate new knowledge on the mixing behaviors of MSM.

Psammoma body (PB) is a common form of calcification in pathological diagnosis and closely relevant to tumours. This paper focuses on the mineralogical characteristics of PBs in ovarian serous cancer and teratoma by using polarization microscope (POM), environmental scanning electron microscope (ESEM), micro-Fourier transform infrared spectroscopy (micro-FT-IR), transmission electron microscope (TEM), micro-area synchrotron radiation X-ray powder diffraction (μ-SRXRD) and fluorescence (μ-SRXRF). Both the PBs in tissues and separated from eight typical cases were investigated. POM and ESEM observation revealed the inside-out growth pattern of PBs. μ-SRXRD and micro-FT-IR results demonstrated the dominant mineral phase of PBs in ovarian serous cancer and teratoma was AB-type carbonate hydroxyapatite (Ca10[(PO4)6-x-y(CO3)x(HPO4)y][(OH)2-u(CO3)u] with 0 ≤ x,y,u ≤ 2). As observed by ESEM and TEM, the layer-rich PBs in teratoma were up to 70 μm and mainly consisted of 5 nm-wide, 5-12 nm-long columnar crystals; the PBs in ovarian serous cancer with a maximum diameter of 35 μm were composed of slightly longer columnar crystals and granulates with 20-100 nm in diameter. The selected area electron diffraction patterns showed dispersed polycrystalline diffraction rings with arching behavior of (002) diffraction, indicating the aggregated nanocrystals grew in the preferred orientation of (002) face. The EDX and μ-SRXRF results together indicated the existence of Na, Mg, Zn and Sr in PBs. These detailed mineralogical characteristics may help uncover the nature of the pathological PBs in ovary.

Full Text Available The aim of this study was to investigate the effects of different types of feedback on learning soccer “head kick” of female adolescent. Novices performed head kick during two practice days [one week apart for two weeks using either internal or external preference attentional focusing instructions. There was also a preference group who choosen their feedback type themselves. Internal focus feedback related with body movements, whereas external focus feedback related with movement effects. The subjects (N=64 were randomly assigned to three groups internal focus feedback group (IFF (N=15, external focus feedback group (EFF (N=15 and preference group (PF (N=34. To promote learning two skill acquisition days for two weeks and one retention day was applied at initial day of third week. Technique of the skill was measured in acquisition days and targeting was measured in retention day. In technique measuring part, EFF group was significantly more accurate than IFF group, PF group was better than those two groups (PF>EFF>IFF. Similar to acquisition phase, EFF group was significantly more successfull than IFF group, PF group was better than those two groups (PF>EFF>IFF in retention phase. Acquisition and retention phase results indicated significance main effect for attentional focus feedback groups. This study results’ indicated that external focus feedback was more effective than internal focus feedback in terms of acquisition and retention of learning soccer head kick for students with limited amount of knowledge about this skill. This study also indicated that not only the source of attention but also control over to source of attention of preference was an important factor in the amount of retention.

Getting patients in the door: medical appointment reminder preferences.

Crutchfield, Trisha M; Kistler, Christine E

2017-01-01

Between 23% and 34% of outpatient appointments are missed annually. Patients who frequently miss medical appointments have poorer health outcomes and are less likely to use preventive health care services. Missed appointments result in unnecessary costs and organizational inefficiencies. Appointment reminders may help reduce missed appointments; particular types may be more effective than other types. We used a survey with a discrete choice experiment (DCE) to learn why individuals miss appointments and to assess appointment reminder preferences. We enrolled a national sample of adults from an online survey panel to complete demographic and appointment habit questions as well as a 16-task DCE designed in Sawtooth Software's Discover tool. We assessed preferences for four reminder attributes - initial reminder type, arrival of initial reminder, reminder content, and number of reminders. We derived utilities and importance scores. We surveyed 251 adults nationally, with a mean age of 43 (range 18-83) years: 51% female, 84% White, and 8% African American. Twenty-three percent of individuals missed one or more appointments in the past 12 months. Two primary reasons given for missing an appointment include transportation problems (28%) and forgetfulness (26%). Participants indicated the initial reminder type (21%) was the most important attribute, followed by the number of reminders (10%). Overall, individuals indicated a preference for a single reminder, arriving via email, phone call, or text message, delivered less than 2 weeks prior to an appointment. Preferences for reminder content were less clear. The number of missed appointments and reasons for missing appointments are consistent with prior research. Patient-centered appointment reminders may improve appointment attendance by addressing some of the reasons individuals report missing appointments and by meeting patients' needs. Future research is necessary to determine if preferred reminders used in practice

Home or hospital? Midwife or physician? Preferences for maternity care provider and place of birth among Western Australian students.

Australian caesarean birth rates have exceeded 30% in most states and are approaching 45%, on average, in private hospitals. Australian midwifery practice occurs almost exclusively in hospitals; less than 3% of women deliver at home or in birthing centres. It is unclear whether the trend towards hospital-based, high interventionist birth reflects preferences of the next generation of maternity care consumers. We conducted a descriptive cross-sectional online survey of 760 Western Australian (WA) university students in 2014, to examine their preferences for place of birth, type of maternity care, mode of birth and attitudes towards birth. More students who preferred midwives (35.8%) had vaginal birth intentions, contested statements that birth is unpredictable and risky, and valued patient-provider relationships. More students who preferred obstetricians (21.8%) expressed concerns about childbirth safety, feared birth, held favourable views towards obstetric technology, and expressed concerns about the impact of pregnancy and birth on the female body. One in 8 students preferred out-of-hospital birth settings, supporting consumer demand for midwife-attended births at home and in birthing centres. Stories and experiences of friends and family shaped students' care provider preferences, rather than the media or information learned at school. Students who express preferences for midwives have significantly different views about birth compared to students who prefer obstetricians. Increasing access to midwifery care in all settings (hospital, birthing centre and home) is a cost effective strategy to decrease obstetric interventions for low risk women and a desirable option for the next generation.

Full Text Available Sodium-glucose cotransporter 2 inhibitor tofogliflozin is a new type of antidiabetic drug for individuals with type 2 diabetes mellitus (T2DM. The aim of this study was to examine in which type of individuals and/or under which conditions tofogliflozin could exert more beneficial effects on body composition and/or glycemic control in Japanese individuals with T2DM. We retrospectively evaluated the effects of tofogliflozin on body composition and/or glycemic control in individuals with T2DM who newly started taking tofogliflozin. After tofogliflozin treatment, body weight was significantly reduced and HbA1c levels were significantly decreased. Body fat mass, skeletal muscle mass, and skeletal muscle index, a marker for sarcopenia, were also reduced after the treatment. In univariate analyses, there was a statistically significant association between the decrease of HbA1c level after tofogliflozin treatment (Δ HbA1c and the following parameters such as HbA1c levels at baseline, visceral fat area (VFA at baseline, and reduction of VFA after the treatment (Δ VFA. Furthermore, in multivariate analyses, HbA1c levels at baseline and duration of diabetes were independently associated with Δ HbA1c. These results suggest that tofogliflozin would be more suitable for relatively obese individuals whose duration of diabetes is relatively short.

In this study, we conducted a content analysis of 243 photographic images of men published on the gay male-oriented blog Queerty.com. We also analyzed 435 user-generated comments from a randomly selected 1-year sample. Focusing on images' body types, we found that the range of body types featured on the blog was quite narrow-the vast majority of images had very low levels of body fat and very high levels of muscularity. Users' body image-related comments typically endorsed and celebrated images; critiques of images were comparatively rare. Perspectives from objectification theory and social comparison theory suggest that the images and commentary found on the blog likely reinforce unhealthy body image in gay male communities.

Classifying patients as "active" or "passive" with regard to healthcare decision making is misleading, since patients have different desires for different components of the decision-making process. Distinguishing patients' desired roles is an essential step towards promoting care that respects and responds to individual patients' preferences. We included items on the 2004 Wisconsin Longitudinal Study mail survey measuring preferences for four components of the decision-making process: physician knowledge of patient medical history, physician disclosure of treatment choices, discussion of treatment choices, and selection of treatment choice. We characterized preference types for 5199 older adults using cluster analysis. Ninety-six percent of respondents are represented by four preference types, all of which prefer maximal information exchange with physicians. Fifty-seven percent of respondents wanted to retain personal control over important medical decisions ("autonomists"). Among the autonomists, 81% preferred to discuss treatment choices with their physician. Thirty-nine percent of respondents wanted their physician to make important medical decisions ("delegators"). Among the delegators, 41% preferred to discuss treatment choices. Female gender, higher educational attainment, better self-rated health, fewer prescription medications, and having a shorter duration at a usual place of care predicted a significantly higher probability of the most active involvement in discussing and selecting treatment choices. The overwhelming majority of older adults want to be given treatment options and have their physician know everything about their medical history; however, there are substantial differences in how they want to be involved in discussing and selecting treatments.

Increasing evidence suggests that action digital game training can improve a variety of perceptual and cognitive abilities, including those that decline most with age. Unfortunately, previous work has found that older adults dislike these games and adherence may be poor for action game-based interventions. The focus of the current study was to better understand the types of games older adults are willing to play and explore predictors of game preference (e.g., gender, age, technology experience, personality). With this information action games might be modified or developed to maximize adherence and cognitive benefit. Older adults were administered a modified version of an existing game questionnaire and a custom game preference survey. Clear preferences were observed that were similar between participants with and without previous digital game experience (with puzzle and intellectually stimulating games being most interesting to older adults in our sample, and massively multiplayer online games and first-person shooters being least interesting). Personality, demographic, and technology experience variables were also collected. Interesting trends suggested the possibility that several demographic and personality variables might be predictive of game preference. Results have implications for future directions of research, designing games that would appeal to older adult audiences, and for how to design custom games to maximize intervention adherence based on individual difference characteristics.

Beneficial autoimmunity at body surfaces - immune surveillance and rapid type 2 immunity regulate tissue homeostasis and cancer.

Science.gov (United States)

Dalessandri, Tim; Strid, Jessica

2014-01-01

Epithelial cells (ECs) line body surface tissues and provide a physicochemical barrier to the external environment. Frequent microbial and non-microbial challenges such as those imposed by mechanical disruption, injury or exposure to noxious environmental substances including chemicals, carcinogens, ultraviolet-irradiation, or toxins cause activation of ECs with release of cytokines and chemokines as well as alterations in the expression of cell-surface ligands. Such display of epithelial stress is rapidly sensed by tissue-resident immunocytes, which can directly interact with self-moieties on ECs and initiate both local and systemic immune responses. ECs are thus key drivers of immune surveillance at body surface tissues. However, ECs have a propensity to drive type 2 immunity (rather than type 1) upon non-invasive challenge or stress - a type of immunity whose regulation and function still remain enigmatic. Here, we review the induction and possible role of type 2 immunity in epithelial tissues and propose that rapid immune surveillance and type 2 immunity are key regulators of tissue homeostasis and carcinogenesis.

Objectives Pediatric obesity is complicated by many factors including psychological issues, such as body dissatisfaction. Body image assessment tools are used with children to measure their acceptance of their body shape or image. Limited research has been conducted with African American and American Indian children to understand their opinions on assessment tools created. This study investigated: (a) children's perception about body image and (b) differences between two body image instruments among low-income, multi-ethnic children. Methods This study uses mixed methodology including focus groups (qualitative) and body image assessment instruments (quantitative). Fifty-one children participated (25 girls, 26 boys); 53% of children identified as African American and 47% as American Indian. The average age was 10.4 years. Open coding methods were used by identify themes from focus group data. SPSS was used for quantitative analysis. Results Children preferred the Figure Rating Scale (FRS/silhouette) instrument over the Children's Body Image Scale (CBIS/photo) because their body parts and facial features were more detailed. Children formed their body image perception with influence from their parents and the media. Children verbalized that they have experienced negative consequences related to poor body image including disordered eating habits, depression, and bullying. Healthy weight children are also aware of weight-related bullying that obese and overweight children face. Conclusions for Practice Children prefer that the images on a body image assessment tool have detailed facial features and are clothed. Further research into body image assessment tools for use with African American and American Indian children is needed.

The association of hand preference and sensation seeking behavior.

Science.gov (United States)

Kuderer, Sonja; Kirchengast, Sylvia

Although the human body shows a superficial symmetry, the disparate functions and skills of both body halves lead to an asymmetrical use. As a result, lateral preferences are detectable, which also include the favoured use of one hand ('handedness'). The collection of questionnaire data on sensation seeking and the conduction of behavioral handedness tasks by 55 research participants enabled the investigation of the interaction of handedness and sensation seeking. For this procedure the age-homogeneous study population is divided according to the Handedness-Index (HI) - a calculated value, indicating the practical hand preference. The results reveal a stronger lateralization in right-handed participants as well as a difference in the mean value of hand use in the three handedness groups. Sensation seeking behavior shows significant negative correlations with age as well as with the HI. Higher scores of left-handers in Experience Seeking (ES), Sensation Seeking (SS) as well as in Thrill and Adventure Seeking (TAS) indicate a larger risk investment in this handedness group. Hence, the results of this study suggest that handedness is a strong indicator of risk behavior.

Girls and boys differ in their preferences for toys such as dolls and trucks. These sex differences are present in infants, are seen in non-human primates, and relate, in part, to prenatal androgen exposure. This evidence of inborn influences on sex-typed toy preferences has led to suggestions that object features, such as the color or the shape of toys, may be of intrinsically different interest to males and females. We used a preferential looking task to examine preferences for different toys, colors, and shapes in 120 infants, ages 12, 18, or 24 months. Girls looked at dolls significantly more than boys did and boys looked at cars significantly more than girls did, irrespective of color, particularly when brightness was controlled. These outcomes did not vary with age. There were no significant sex differences in infants' preferences for different colors or shapes. Instead, both girls and boys preferred reddish colors over blue and rounded over angular shapes. These findings augment prior evidence of sex-typed toy preferences in infants, but suggest that color and shape do not determine these sex differences. In fact, the direction of influence could be the opposite. Girls may learn to prefer pink, for instance, because the toys that they enjoy playing with are often colored pink. Regarding within sex differences, as opposed to differences between boys and girls, both boys and girls preferred dolls to cars at age 12-months. The preference of young boys for dolls over cars suggests that older boys' avoidance of dolls may be acquired. Similarly, the sex similarities in infants' preferences for colors and shapes suggest that any subsequent sex differences in these preferences may arise from socialization or cognitive gender development rather than inborn factors.

Recalled sex-typed behavior in childhood and sports' preferences in adulthood of heterosexual, bisexual, and homosexual men from Brazil, Turkey, and Thailand.

This research used interview and questionnaire data from homosexual (n = 177), bisexual (n = 157), and heterosexual (n = 544) men between 20 and 30 years of age among lower class men and university students in three countries: Brazil, Thailand, and Turkey. The main goal of the study was to examine the recalled childhood sex-typed behavior and adult sports preferences that distinguish homosexuals from bisexuals and heterosexuals. In all three cultures and both social groups, homosexual men were almost always more likely as children to have wanted to be a girl, to cross-dress, to play with girls, to do girls' tasks, and to practice fewer sports. They were also less likely to bully others or to engage in physical fights. As children, homosexual men were more likely to prefer swimming and playing volleyball rather than soccer and, as adults, they preferred watching gymnastics and swimming over soccer. The bisexuals scored intermediate mostly in "desire to be a girl" and "cross-dressing," although they were much closer to the heterosexuals. These results, coupled with previous cross-cultural research, suggest that cross-gender behavior in childhood may characterize most male homosexuals regardless of their cultural milieu.

Oblique Axis Body Fracture: An Unstable Subtype of Anderson Type III Odontoid Fractures—Apropos of Two Cases

Full Text Available Purpose. Anderson type III odontoid fractures have traditionally been considered stable and treated conservatively. However, unstable cases with unfavorable results following conservative treatment have been reported. Methods. We present the cases of two patients who sustained minimally displaced Anderson type III fractures with a characteristic fracture pattern that we refer to as “oblique type axis body fracture.” Results. The female patients aged 90 and 72 years, respectively, were both diagnosed with minimally displaced Anderson type III fractures. Both fractures had a characteristic “oblique type” fracture pattern. The first patient was treated conservatively with cervical spine immobilization in a semirigid collar. However, gross displacement was noted at the 6-week follow-up visit. The second patient was therefore treated operatively by C1–C3/4 posterior fusion and the course was uneventful. Conclusions. Oblique type axis body fractures resemble a highly unstable subtype of Anderson type III fractures with the potential of severe secondary deformity following conservative treatment, irrespective of initial grade of displacement. The authors therefore warrant a high index of suspicion for this injury and suggest early operative stabilization.

Preferred chewing side is a still controversial matter and various methods used have yielded some inconsistencies. The aim of this study is to compare the preference determined in different conditions. Nineteen healthy subjects were offered hard (walnut) and soft (cake) foods, while the electromyography was recorded from their masseter muscles, in 2009 in the Research Center of Physical Medicine and Rehabilitation, Tabriz University of Medical Sciences, Tabriz, Iran. Four occurrences were determined as the side of the first chews/all chews in the two food types, and then analyzed for correlations and agreements. For hard food 73.68% and for soft food 57.89% of the subjects showed preference. The comparison of all chews showed a highly significant preference towards the right side in both food types (p=0.000 & 0.003). There was both correlation and agreement between the first chew preferences in both food types, and an agreement between the first and all chew preferences in the hard food. Therefore, there seems to exist some laterality in mastication, which is more explicit when using hard food and assessing all chews. PMID:22993653

Thermoregulatory behavior and orientation preference in bearded dragons.

Black, Ian R G; Tattersall, Glenn J

2017-10-01

The regulation of body temperature is a critical function for animals. Although reliant on ambient temperature as a heat source, reptiles, and especially lizards, make use of multiple voluntary and involuntary behaviors to thermoregulate, including postural changes in body orientation, either toward or away from solar sources of heat. This thermal orientation may also result from a thermoregulatory drive to maintain precise control over cranial temperatures or a rostrally-driven sensory bias. The purpose of this work was to examine thermal orientation behavior in adult and neonatal bearded dragons (Pogona vitticeps), to ascertain its prevalence across different life stages within a laboratory situation and its interaction with behavioral thermoregulation. Both adult and neonatal bearded dragons were placed in a thermal gradient and allowed to voluntarily select temperatures for up to 8h to observe the presence and development of a thermoregulatory orientation preference. Both adult and neonatal dragons displayed a non-random orientation, preferring to face toward a heat source while achieving mean thermal preferences of ~ 33-34°C. Specifically, adult dragons were more likely to face a heat source when at cooler ambient temperatures and less likely at warmer temperatures, suggesting that orientation behavior counter-balances local selected temperatures but contributes to their thermoregulatory response. Neonates were also more likely to select cooler temperatures when facing a heat source, but required more experience before this orientation behavior emerged. Combined, these results demonstrate the importance of orientation to behavioral thermoregulation in multiple life stages of bearded dragons. Copyright © 2017 Elsevier Ltd. All rights reserved.

Incongruence in body image and body mass index: A surrogate risk marker in Black women for type 2 diabetes mellitus

Full Text Available Background: Excess weight contributes to the development and progression of Type 2 diabetes mellitus (T2DM. Distorted body image amongst urban Black women and the perception that thinness is linked with HIV, may however be compounding the problem, particularly in areas with a high HIV burden. Objectives: This study aimed to compare the perception of body image in urban Black women with and without T2DM. Methods: A cross-sectional comparative study was conducted on 328 Black women systematically sampled into two groups (with and without T2DM. Body mass index (BMI (weight [kg]/height[m2] was determined and the adapted Stunkard Body Image Silhouettes for Black women was used to determine perceived body image (PBI. Results: Seventy-two per cent had T2DM and in this group 89% were obese, with a mean BMI of 39.5 kg/m2 (s.d. ± 8.5. In the non-diabetes group (NDG 44% were obese, with a mean BMIof 31.3 kg/m2 (s.d. ± 9.0 Black women underestimated their body image across all weight categories (p < 0.05. Both groups (99% of the study group also perceived thinness as being associated with HIV. Conclusions: This study identified an incongruence between PBI and actual BMI amongst urban Black women. This, combined with their belief that thinness is associated with HIV, places those with T2DM at risk of secondary complications arising from diabetes mellitus, and those without diabetes mellitus at a higher risk of developing T2DM. A discrepancy between PBI and BMI may therefore serve as a risk marker to alert clinicians to use a more ethno-cultural specific approach in engaging with urban Black women regarding weight loss strategies in the future.

PREFERRED MODALITY INFLUENCES ON EXERCISE-INDUCED MOOD CHANGES

Full Text Available The present study tested, both retrospectively and prospectively, exercise-induced mood changes among regular exercisers. Specifically, it examined the extent to which preferred exercise modality promoted greater mood benefits. A group of 25 exercise participants (M = 35.5 yr., SD = 10.5 yr. took part in the study. All participants had exercised at least three times a week (M = 3.5, SD = 2.3 during the previous year. Participants completed a 14-item Exercise Preference Questionnaire to provide retrospective evaluations of their most- and least-preferred type of exercise. For the prospective investigation, participants completed the Brunel Mood Scale (BRUMS 15 minutes before and immediately after their most- and least-preferred exercise sessions. One week separated completion of each exercise session. Retrospective assessment of exercise-induced mood changes showed strong support for enhanced mood following the preferred mode of exercise. Also, as hypothesized, prospective results showed that mood enhancement was greater following the preferred exercise modality, but significant mood enhancement also occurred following the least-preferred modality among experienced exercisers. In conclusions, findings support the principle that exercise can provide psychological benefits to its participants, in the form of positive affective outcomes, something that appears to be enhanced by preferred exercise modality. Given the important public health implications of exercise adherence, future research should seek to further investigate the mechanisms of exercise-induced mood enhancement

The Body and the Beautiful: Health, Attractiveness and Body Composition in Men's and Women's Bodies.

Mary-Ellen Brierley

Full Text Available The dominant evolutionary theory of physical attraction posits that attractiveness reflects physiological health, and attraction is a mechanism for identifying a healthy mate. Previous studies have found that perceptions of the healthiest body mass index (weight scaled for height; BMI for women are close to healthy BMI guidelines, while the most attractive BMI is significantly lower, possibly pointing to an influence of sociocultural factors in determining attractive BMI. However, less is known about ideal body size for men. Further, research has not addressed the role of body fat and muscle, which have distinct relationships with health and are conflated in BMI, in determining perceived health and attractiveness. Here, we hypothesised that, if attractiveness reflects physiological health, the most attractive and healthy appearing body composition should be in line with physiologically healthy body composition. Thirty female and 33 male observers were instructed to manipulate 15 female and 15 male body images in terms of their fat and muscle to optimise perceived health and, separately, attractiveness. Observers were unaware that they were manipulating the muscle and fat content of bodies. The most attractive apparent fat mass for female bodies was significantly lower than the healthiest appearing fat mass (and was lower than the physiologically healthy range, with no significant difference for muscle mass. The optimal fat and muscle mass for men's bodies was in line with the healthy range. Male observers preferred a significantly lower overall male body mass than did female observers. While the body fat and muscle associated with healthy and attractive appearance is broadly in line with physiologically healthy values, deviations from this pattern suggest that future research should examine a possible role for internalization of body ideals in influencing perceptions of attractive body composition, particularly in women.

Current health and preferences for life-prolonging treatments: an application of prospect theory to end-of-life decision making.

Science.gov (United States)

Winter, Laraine; Parker, Barbara

2007-10-01

As a substantial body of research attests, the acceptability of life-prolonging treatment (e.g., tube feeding) tends to be greater among people in worse health than among healthier ones. Because a decision for or against a life-prolonging treatment represents a choice between two prospects-life (usually in poor health) and death-we propose a decision model, Prospect Theory, as a theoretical account of this phenomenon. Prospect Theory postulates that pairs of distant prospects are less distinguishable than pairs of closer ones. Thus, to healthy individuals, the prospects of death and life in poor health would both be remote, and therefore, the distinction between them, small. To less healthy individuals, however, the difference between the same pairs of prospects would appear greater, and therefore, life-prolonging treatment may be more acceptable. In a cross-sectional study of 304 community-dwelling people, aged 60 years and over in the Philadelphia area, USA, preferences for 4 life-prolonging treatments in 9 health scenarios were examined in relation to participants' current health, operationalized as number of deficits in physical functioning. As predicted, less healthy people expressed stronger preferences for all life-prolonging treatments compared with healthier ones, with differences greatest in the worse-health scenarios. Preferences also varied by health scenario, with any treatment preferred in the better health scenarios. Treatment preferences did not differ by type of treatment, depressed mood or any demographic characteristic except race, with African-Americans expressing stronger treatment preferences. Implications for advance care planning are discussed.

Body Size Preference of Marine Animals in Relation to Extinction Selectivity

Science.gov (United States)

Sriram, A.; Idgunji, S.; Heim, N. A.; Payne, J.

2014-12-01

Our project encompasses an extremely specific aspect in relation to the five mass extinctions in geologic history. We asked ourselves whether larger or smaller body sizes would be better suited for surviving a mass extinction. To conduct research for our project, we used the body sizes of 17,172 marine animal genera as our primary data. These animals include echinoderms, arthropods, chordates, mollusks, and brachiopods. These creatures are perfect model organisms in terms of finding data on them because they have an excellent fossil record, and are well documented. We focused on the mean body size of these animals before and after each of the five mass extinctions (end-Ordovician, Late Devonian, end-Permian, end-Triassic, and end-Cretaceous). Our hypothesis was that the average biovolume of animals increased after each of the extinctions, with the mean size being greater after than it was before. Our size data is from the Ellis & Messina Catalogue of Ostracoda and the Treatise on Invertebrate Paleontology. We obtained stratigraphic range data The Treatise and Sepkoski (2002). In our analyses, we compared the mean size of the different animal genera before and after each extinction event. We further partitioned size change across mass extinction boundaries into three categories: the surviving genera, the extinct genera, and the newly originating genera that came about after the extinction. According to our analyses, the mean sizes did not change significantly from the genera living during the stages before the extinctions and after the extinctions. From our results, we can assume that there were not enough major increases in the overall volume of the organisms to warrant a definite conclusion that extinctions lead to larger body sizes. Further support for our findings came from the T-tests in our R code. Only the Cretaceous period showed true evidence for size changing because of the extinction; in this case, the mean size decreased. T-tests for the Cretaceous

The geometry of distributional preferences and a non-parametric identification approach: The Equality Equivalence Test.

Science.gov (United States)

Kerschbamer, Rudolf

2015-05-01

This paper proposes a geometric delineation of distributional preference types and a non-parametric approach for their identification in a two-person context. It starts with a small set of assumptions on preferences and shows that this set (i) naturally results in a taxonomy of distributional archetypes that nests all empirically relevant types considered in previous work; and (ii) gives rise to a clean experimental identification procedure - the Equality Equivalence Test - that discriminates between archetypes according to core features of preferences rather than properties of specific modeling variants. As a by-product the test yields a two-dimensional index of preference intensity.

Effects of three types of free-stall surfaces on preferences and stall usage by dairy cows.

2003-02-01

One important criterion in choosing appropriate housing systems for dairy cattle is that the freestall provides a comfortable surface for the cow. This paper describes two experiments testing the effects of commonly used lying surfaces on stall preference and stall usage by Holstein cows. In both experiments, 12 cows were housed individually in separate pens. Each pen contained three free stalls with a different surface: deep-bedded sawdust, deep-bedded sand, and a geotextile mattress covered with 2 to 3 cm of sawdust. The animals were restricted to each surface in turn, in a random order for either 2 (Experiment 1) or 3 d (Experiment 2). Both before and after this restriction phase, the animals were allowed access to all three surfaces, and preference was determined, based on lying times. Of the 12 cows used in Experiment 1, 10 preferred sawdust before and nine after the restriction phase. During the restriction phase, average lying times and number of lying events during the restriction phase were significantly lower for the sand-bedded stalls (P sand bedded stalls. In this experiment, about half the cows preferred sand and half sawdust, after the restriction phase. During the restriction phase of experiment, lying times and number of lying events were lower, and standing times were higher when the animals were restricted to the mattresses compared to either sand or sawdust (P < or = 0.05). These results indicate that (1) free stall surface can affect both stall preferences and stall usage, and (2) mattresses are less preferred.

Overwintering in temperate regions is a prominent mortality risk for invertebrates and may affect their behaviour and body condition. Pardosa alacris is a common ground dwelling spider in central European native and plantation forests, and habitat type and prey availability may play important roles in their overwintering. The effect of overwintering on body condition and behaviour of spiders in semi natural and exotic habitats is relatively unknown. Here we assess the effects of winter on spiders from native poplar and exotic pine plantations. The locomotory behaviour of P. alacris (distance covered and speed) was assessed by tracking their movement in a white circular plastic arena. We assessed body condition, body size, and total fat content. Forest type and sex had significant effects on body length. Fat content was significantly higher in the spring than in autumn, and spiders covered larger distances and were faster in autumn than in spring. Fat content had a significant negative effect on average speed. Spiders in native forests were smaller but grew more during the winter than in exotic plantations, possibly due to higher prey availability in native forests. Visually-hunting predators may significantly affect spiders. Fat spiders with better body condition moved less, and were thus less detectable by predators. However the low movement rate may result in a low rate of encountering prey items, thus lowering feeding efficiency.

Quantitative neuropathological study of Alzheimer-type pathology in the hippocampus: comparison of senile dementia of Alzheimer type, senile dementia of Lewy body type, Parkinson's disease and non-demented elderly control patients.

A Lewy body dementing syndrome in the elderly has been recently described and designated senile dementia of Lewy body type (SDLT) on the basis of a distinct clinicopathological profile. The pathological changes seen in SDLT include the presence of cortical Lewy bodies (LB) frequently, but not invariably, associated with senile plaque (SP) formation. Whilst neocortical neurofibrillary tangles (NFT) are sparse or absent, a proportion of these cases show involvement of the temporal archicortex by lesions comprising Alzheimer-type pathology (ATP, i.e. NFT, SP and granulovacuolar degeneration [GVD]). Thus the relationship between SDLT and senile dementia of Alzheimer type (SDAT) is complex and controversial. In this study quantitative neuropathology was used to compare the intensity and distribution of ATP in the hippocampus and entorhinal cortex of 53 patients from 3 disease groups (SDLT, SDAT, Parkinson's disease (PD)) and a group of neurologically and mentally normal elderly control patients. For most brain areas examined the extent of ATP between the patient groups followed the trend SDAT greater than SDLT greater than PD greater than control. Statistical comparison of these groups revealed significant differences between the mean densities of NFT, SP and GVD although individual cases showed considerable variability. These results confirm additional pathological differences between SDAT and SDLT regarding the intensity of involvement of the temporal archicortex by ATP. Many patients with Lewy body disorders (LBdis) show a predisposition to develop ATP albeit in a more restricted distribution (e.g. low or absent neocortical NFT) and at lower densities than is found in SDAT. Some cases of SDLT show minimal SP and NFT formation in both neocortex and archicortex supporting previously published data distinguishing this group from Alzheimer's disease.

Barbie doll ownership is high among girls in early primary school. It has been suggested that exposure to Barbie impacts negatively on body image. The present study sought to investigate the effect of exposure to Barbie on young girls' thin-ideal internalisation, body esteem, and body dissatisfaction. Participants were 160 girls (aged 5-8 years) from Adelaide, South Australia. They were randomly allocated one of three Barbie conditions (physical engagement, physical observation, print observation) or to a control toy. Results indicated that exposure to Barbie, irrespective of format, led to higher thin-ideal internalisation than exposure to the control, but had no impact on body esteem or body dissatisfaction. This suggests that interacting with Barbie may encourage girls in early primary school to adopt a preference for a thin body, but with no immediate effect on body image. The long-term impact of Barbie exposure on body image remains unknown. Copyright © 2016 Elsevier Ltd. All rights reserved.

Increasing evidence suggests that action digital game training can improve a variety of perceptual and cognitive abilities, including those that decline most with age. Unfortunately, previous work has found that older adults dislike these games and adherence may be poor for action game-based interventions. The focus of the current study was to better understand the types of games older adults are willing to play and explore predictors of game preference (e.g., gender, age, technology experience, personality). With this information action games might be modified or developed to maximize adherence and cognitive benefit. Older adults were administered a modified version of an existing game questionnaire and a custom game preference survey. Clear preferences were observed that were similar between participants with and without previous digital game experience (with puzzle and intellectually stimulating games being most interesting to older adults in our sample, and massively multiplayer online games and first-person shooters being least interesting). Personality, demographic, and technology experience variables were also collected. Interesting trends suggested the possibility that several demographic and personality variables might be predictive of game preference. Results have implications for future directions of research, designing games that would appeal to older adult audiences, and for how to design custom games to maximize intervention adherence based on individual difference characteristics.

Many studies in Western societies have shown that women prefer relatively taller men as potential partners, whereas men prefer women who are slightly shorter than themselves. Here, we discuss possible limitations of previous results within the context of the stimuli used (i.e., differences in the perceived body size of female silhouettes). Our results show that, at least in a Polish sample (N=231), modified stimuli did not essentially change the observed male-taller preferences. In contrast, we report height preferences in a traditional ethnic group, the Datoga people from Tanzania (N=107), in which men and women preferred extreme sexual dimorphism in stature (SDS) sets (i.e., men and women chose women much taller or much shorter than themselves). Thus, our data do not accord with the suggestion of a universal preference for taller men, but rather suggests that height preferences may be influenced by cultural, environmental, and ecological conditions.

Patient preferences can influence the outcomes of treatment and so understanding and organizing health-care services around these preferences is vital. To explore patient preferences for types of community pharmacy-based asthma services, to investigate the influence of "experience" in molding preferences for such services, and to identify aspects of the services that patients prefer over others. Semistructured face-to-face interviews were conducted with a convenience sample of two types of asthma patients: (1) those naïve to a specialized asthma service and (2) those who had experienced a specialized asthma service. Interviews were audio-recorded, transcribed verbatim, and thematically analyzed. Eighteen interviews were conducted (8 experienced patients, 10 naïve patients). The majority of the patients wanted the pharmacist to play a greater role in their asthma management. Patients experiencing increased levels of service had increased levels of expectations as well as more specific preferences for various aspects of the service. The key aspects of an asthma service that all patients wanted their pharmacists to provide were the provision of information about asthma and its medications, lung function testing and monitoring of their asthma, and checking/correcting their inhaler technique. Patients also expressed a desire for skilled communication and behavioral aspects from the pharmacist such as friendliness, empathy, attentiveness, and dedicated time. Patients highlighted the importance of privacy in the pharmacy. There was a high level of satisfaction toward the currently delivered asthma service among both naïve and experienced patients. The provision of the specialized service was associated with increased patient loyalty to the particular pharmacy. All patients indicated a willingness to participate in future pharmacy-delivered specialized asthma services. Elements of the specialized pharmacy-based asthma services important from a patient's perspective were

New maize varieties have been biofortified with provitamin A, mainly a-carotene, which renders the grain yellow or orange. Unfortunately, many African consumers prefer white maize. The maize consumption patterns in Africa are, however, not known. To determine which maize products African consumers prefer to purchase and which maize preparations they prefer to eat. A survey of 600 consumers was conducted in Nairobi, Kenya, at three types of maize outlets: posho mills (small hammer mills), kiosks, and supermarkets. Clients of posho mills had lower incomes and less education than those of kiosks and supermarkets. The preferred maize product of the posho-mill clients was artisanal maize meal; the preferred product of the others was industrial maize meal. Maize is the preferred staple for lunch and dinner, eaten as a stiff porridge (ugali), followed by boiled maize and beans (githeri), regardless of socioeconomic background. For breakfast, only half the consumers prefer maize, mostly as a soft porridge (uji). This proportion is higher in low-income groups. Consumers show a strong preference for white maize over yellow, mostly for its organoleptic characteristics, and show less interest in biofortified maize. Maize is the major food staple in Nairobi, mostly eaten in a few distinct preparations. For biofortified yellow maize to be accepted, a strong public awareness campaign to inform consumers is needed, based on a sensory evaluation and the mass media, in particular on radio in the local language.

Daughter preference in Japan: A reflection on gender role attitudes?

Full Text Available BACKGROUND Unlike other East Asian nations where preference for sons over daughters still prevails, gender preference for children in Japan has progressively shifted from son preference to a noticeable daughter preference over the past few decades. This emergence of daughter preference is surprising given that gender relations are more traditional in Japan than in other advanced countries. OBJECTIVE I focus on the extent to which individuals' gender preferences are shaped by their gender role attitudes and evaluate whether daughter preference is a reflection of convergence or a persistent divergence in gender roles in Japan. METHODS I use data from the Single Persons subset of the 11th Japanese National Fertility Survey conducted by the National Institute of Population and Social Security Research in 1997. Using multinomial logistic regression, I estimate the relationship between Japanese singles' gender role attitudes and their type of gender preference for children. RESULTS Findings suggest that the effect of gender role attitudes on one's child gender preference differs for men and women. Overall, while daughter preference is associated with nontraditional gender role attitudes for men, daughter preference is associated with traditional attitudes for women. CONCLUSIONS Traditionalism is still driving gender preference, though in a different way for men and women. Emerging daughter preference may not simply be a reflection of improvements in women's status, but in fact it is likely that persistent divergence in gender roles remain in Japan.

Sexual preference for the opposite sex is a fundamental behavior underlying reproductive success, but the neural mechanisms remain unclear. Here, we examined the role of dopamine signaling in the nucleus accumbens core (NAcc) in governing chemosensory-mediated preference for females in TrpC2 -/- and wild-type male mice. TrpC2 -/- males, deficient in VNO-mediated signaling, do not display mating or olfactory preference toward females. We found that, during social interaction with females, TrpC2 -/- males do not show increased NAcc dopamine levels, observed in wild-type males. Optogenetic stimulation of VTA-NAcc dopaminergic neurons in TrpC2 -/- males during exposure to a female promoted preference response to female pheromones and elevated copulatory behavior toward females. Additionally, we found that signaling through the D1 receptor in the NAcc is necessary for the olfactory preference for female-soiled bedding. Our study establishes a critical role for the mesolimbic dopaminergic system in governing pheromone-mediated responses and mate choice in male mice. Copyright © 2017 The Authors.

This study investigates people's preconceptions of green roofs and their visual preference for different green roof design alternatives in relation to behavioral, social and demographical variables. The investigation was performed as a visual preference study using digital images created to represent eight different alternatives: gravel roof, extensive green roof with Sedums not in flower, extensive green roof with sedums in bloom, semi-intensive green roof with sedums and ornamental grasses, semi-intensive green roof with shrubs, intensive green roof planted with a lawn, intensive green roof with succulent and trees and intensive green roof with shrubs and trees. Using a Likert-type scale, 450 respondents were asked to indicate their preference for each digital image. Results indicated that respondents' sociodemographic characteristics and childhood environmental background influenced their preferences toward different green roof types. Results also showed that green roofs with a more careful design, greater variety of vegetation structure, and more variety of colors were preferred over alternatives. Copyright © 2013 Elsevier Ltd.

Gynecomastia is a common finding in male subjects which incidence varies widely in the world population. In adolescents, it is frequently temporary but, if it becomes persistent, it generates considerable embarrassment, inducing the patients to seek surgical consultation. Even in patients with good body contour, gynecomastia creates even greater distress considering the special attention given by these subjects to their physical appearance. The authors present their experience in the treatment of gynecomastia comparing different body types of patients with the aim to investigate dissimilar expectations, needs and surgical outcomes thus optimizing the management of the pathological condition, achieving high levels of agreement and reducing unsatisfied patients arising from cosmetic surgery. Between January 2007 and January 2015, 312 selected patients have been treated surgically for gynecomastia. Patients were grouped according to their physical aspect: 97 were classified as high muscle mass body type (group A), 106 as normal (group B) and 109 as overweight patients (group C). All of them were adults ranging in age between 18 and 52 years. Follow-up ranged from 12 to 60 months. In all cases, an excision of the gland in the form of a subcutaneous mastectomy was performed; the most common surgical access was in the inferior part of the areola. No breast cancers were found at the histological examinations. Also, no skin or areola necrosis have been referred, and no recurrence of gynecomastia disorder has been reported. Six cases of seroma (limited to the fatty gynecomastia) and 3 cases of hematomas (requiring immediate surgical revision) were found. Although the patients in group B resulted more distressed by the disorder, higher levels of postoperative satisfaction were recorded in this group. The study demonstrates the importance of the different management of the same disorder according to the different patients' expectations, related to the different body type. Our

In a previous study we reported no difference in the overall beta-amyloid protein (beta AP) load between Alzheimer's disease (AD) and senile dementia of the Lewy body type (SDLT). However, it is possible that differences in the morphology of beta AP plaque types exist, analogous to the differences in cytoskeletal pathology found in these two disorders. We have carried out a quantitative image analysis of plaque subtypes in the temporal lobe of AD (n = 8), SDLT (n = 9) and control (n = 11) cases. Measurements of beta AP load and plaque density were consistently higher in AD and SDLT than in controls. When AD and SDLT cases were compared no differences were seen in either the density or relative proportions of classic and diffuse plaques. Based on these results we suggest that the variation in the clinical course of these diseases reflects differences in the cytoskeletal pathology, whereas the final stages of profound dementia common to both disorders is associated with the deposition of beta AP.

It has long been known that the bedding type animals are housed on can affect breeding behavior and cage environment. Yet little is known about its effects on evoked behavior responses or non-reflexive behaviors. C57BL/6 mice were housed for two weeks on one of five bedding types: Aspen Sani Chips® (standard bedding for our institute), ALPHA-Dri®, Cellu-Dri™, Pure-o’Cel™ or TEK-Fresh. Mice housed on Aspen exhibited the lowest (most sensitive) mechanical thresholds while those on TEK-Fresh exhibited 3-fold higher thresholds. While bedding type had no effect on responses to punctate or dynamic light touch stimuli, TEK-Fresh housed animals exhibited greater responsiveness in a noxious needle assay, than those housed on the other bedding types. Heat sensitivity was also affected by bedding as animals housed on Aspen exhibited the shortest (most sensitive) latencies to withdrawal whereas those housed on TEK-Fresh had the longest (least sensitive) latencies to response. Slight differences between bedding types were also seen in a moderate cold temperature preference assay. A modified tactile conditioned place preference chamber assay revealed that animals preferred TEK-Fresh to Aspen bedding. Bedding type had no effect in a non-reflexive wheel running assay. In both acute (two day) and chronic (5 week) inflammation induced by injection of Complete Freund’s Adjuvant in the hindpaw, mechanical thresholds were reduced in all groups regardless of bedding type, but TEK-Fresh and Pure-o’Cel™ groups exhibited a greater dynamic range between controls and inflamed cohorts than Aspen housed mice.

Indication of total body irradiation (TBI) in adult allogeneic bone marrow transplantation was discussed in comparison with non-TBI method of busulfan and cyclophosphamide (BU+CY). Each method has unique advantages and disadvantages. Concerning adverse effects of interstitial pneumonia, liver dysfunction and so on, there are no significant differences in both methods. TBI method should be preferably indicated for lymphatic leukemias and leukemias involving central nervous systems. It is important to clarify what kinds of combination regimen depending on the type and the stage of disease are most suitable for the longer survival of patients with leukemia or aplastic anemia by multicentric randomized study.

Beneficial Autoimmunity at Body Surfaces – Immune Surveillance and Rapid Type 2 Immunity Regulate Tissue Homeostasis and Cancer

Science.gov (United States)

Dalessandri, Tim; Strid, Jessica

2014-01-01

Epithelial cells (ECs) line body surface tissues and provide a physicochemical barrier to the external environment. Frequent microbial and non-microbial challenges such as those imposed by mechanical disruption, injury or exposure to noxious environmental substances including chemicals, carcinogens, ultraviolet-irradiation, or toxins cause activation of ECs with release of cytokines and chemokines as well as alterations in the expression of cell-surface ligands. Such display of epithelial stress is rapidly sensed by tissue-resident immunocytes, which can directly interact with self-moieties on ECs and initiate both local and systemic immune responses. ECs are thus key drivers of immune surveillance at body surface tissues. However, ECs have a propensity to drive type 2 immunity (rather than type 1) upon non-invasive challenge or stress – a type of immunity whose regulation and function still remain enigmatic. Here, we review the induction and possible role of type 2 immunity in epithelial tissues and propose that rapid immune surveillance and type 2 immunity are key regulators of tissue homeostasis and carcinogenesis.

Algorithms for Learning Preferences for Sets of Objects

Wagstaff, Kiri L.; desJardins, Marie; Eaton, Eric

2010-01-01

A method is being developed that provides for an artificial-intelligence system to learn a user's preferences for sets of objects and to thereafter automatically select subsets of objects according to those preferences. The method was originally intended to enable automated selection, from among large sets of images acquired by instruments aboard spacecraft, of image subsets considered to be scientifically valuable enough to justify use of limited communication resources for transmission to Earth. The method is also applicable to other sets of objects: examples of sets of objects considered in the development of the method include food menus, radio-station music playlists, and assortments of colored blocks for creating mosaics. The method does not require the user to perform the often-difficult task of quantitatively specifying preferences; instead, the user provides examples of preferred sets of objects. This method goes beyond related prior artificial-intelligence methods for learning which individual items are preferred by the user: this method supports a concept of setbased preferences, which include not only preferences for individual items but also preferences regarding types and degrees of diversity of items in a set. Consideration of diversity in this method involves recognition that members of a set may interact with each other in the sense that when considered together, they may be regarded as being complementary, redundant, or incompatible to various degrees. The effects of such interactions are loosely summarized in the term portfolio effect. The learning method relies on a preference representation language, denoted DD-PREF, to express set-based preferences. In DD-PREF, a preference is represented by a tuple that includes quality (depth) functions to estimate how desired a specific value is, weights for each feature preference, the desired diversity of feature values, and the relative importance of diversity versus depth. The system applies statistical

An animal model has been used in an investigation of taste dysfunction, which is a side effect of radiotherapy of the head and neck. Rats were 60 Co γ-irradiated (1.5, 5 or 20 Gy) to the head, abdomen or tail, and fluid preference was measured with a two-bottle free choice technique up to 120 days post-irradiation. Doses of 1.5 or 5 Gy delivered to the head, abdomen or tail did not change fluid preference, body weight or total fluid intake, but there were significant differences in all three in 20 Gy head-irradiated rats only. There were differences in the changes with time after irradiation in fluid intake and preference for these head irradiated animals. (UK)

Music preference in degus (Octodon degus: Analysis with Chilean folk music.

2018-05-01

Full Text Available Most nonhuman animals do not show selective preference for types of music, but researchers have typically employed only Western classical music in such studies. Thus, there has been bias in music choice. Degus (Octodon degus, originally from the mountain areas of Chile, have highly developed vocal communication. Here, we examined music preference of degus using not only Western classical music (music composed by Bach and Stravinsky, but also South American folk music (Chilean and Peruvian. The degus preferred the South American music to the Western classical music but did not show selective preference between the two Western classical music choices. Furthermore, the degus preferred the Chilean to the Peruvian music to some extent. In the second experiment, we examined preference for music vs. silence. Degus overall showed a preference for Chilean music over silence, but preferred silence over Western music. The present results indicate that the previous negative data for musical preference in nonhuman animals may be due to biased music selection (Krause, 2012. Our results suggest the possibility that the soundscape of an environment influences folk music created by native peoples living there and the auditory preference of other resident animals there.

Population genetic segmentation of MHC-correlated perfume preferences.

Hämmerli, A; Schweisgut, C; Kaegi, M

2012-04-01

It has become difficult to find a matching perfume. An overwhelming number of 300 new perfumes launch each year, and marketing campaigns target pre-defined groups based on gender, age or income rather than on individual preferences. Recent evidence for a genetic basis of perfume preferences, however, could be the starting point for a novel population genetic approach to better match perfumes with people's preferences. With a total of 116 participants genotyped for alleles of three loci of the major histocompatibility complex (MHC), the aim of this study was to test whether common MHC alleles could be used as genetic markers to segment a given population into preference types. Significant deviations from random expectations for a set of 10 common perfume ingredients indicate how such segmentation could be achieved. In addition, preference patterns of participants confronted with images that contained a sexual communication context significantly differed in their ratings for some of the scents compared with participants confronted with images of perfume bottles. This strongly supports the assumption that genetically correlated perfume preferences evolved in the context of sexual communication. The results are discussed in the light of perfume customization. © 2011 The Authors. ICS © 2011 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

Chimpanzees' socially maintained food preferences indicate both conservatism and conformity

. This study provides the first evidence that chimpanzees show such conservatism even when the new method employs the identical required behaviour as the first, but for a different reward. Groups of chimpanzees could choose to exchange one of two types of inedible tokens, with each token type being associated...... with a different food reward: one type was rewarded with a highly preferred food (grape) and the other type was rewarded with a less preferred food (carrot). Individuals first observed a model chimpanzee from their social group trained to choose one of the two types of tokens. In one group, this token earned...... a carrot, while in the other, control, group the token earned a grape. In both groups, chimpanzees conformed to the trained model’s choice. This was especially striking for those gaining the pieces of carrot, the less favoured reward. This resulted in a population-level trend of food choices, even when...

Resistance training to increase muscle mass and functional capacity is an integral part of diet and exercise programs for the management of obesity and type 2 diabetes. Low-intensity resistance training with slow movement and tonic force generation (LST) may be a practical and safe regimen for elderly obese individuals but the health benefits are uncertain. This study investigated the effects of LST on body composition and metabolic parameters in obese patients with type 2 diabetes. Twenty-six obese patients with type 2 diabetes engaged in LST training during hospitalization and were advised to maintain this regimen for 12 weeks after discharge. We compared lipid profile, arterial stiffness, and body composition before and after LST training. After 12 weeks of LST training, the ratio of lower extremity muscle mass to body weight increased significantly (0.176 ± 0.028 to 0.184 ± 0.023, mean ± SD), while body fat mass and body fat percentage decreased significantly (36.2 ± 10.9 kg to 34.3 ± 9.4 kg and 41.2 ± 8.6% to 40.1 ± 7.7%, respectively). Moreover, high-density lipoprotein cholesterol was significantly increased (42.2 ± 14 mg/dl to 46.3 ± 12.4 mg/dl) and both free fatty acids and lipoprotein(a) were decreased (665.2 ± 212.1 μEq/l to 525.4 ± 231.3 μEq/l and 15.4 ± 18 mg/dl to 13.8 ± 18 mg/dl, respectively). No significant change was observed in arterial stiffness. Although this study was a non-controlled investigation and some confounding factors including dietary intake, medication and compliance with training might affect the study result, a brief (12-week) LST training program may be a safe and effective strategy for the management of obesity and type 2 diabetes.

As gatekeeper they are supposed to manage the growing demand for specialist services and as patient advocate they should be responsive to patients' preferences. We used an innovative approach to develop a referral guideline for patients with chronic knee pain that explicitly incorporates patients' preferences. Methods. A guideline development group of 12 members including patients, GPs, orthopaedic surgeons and other health care professionals used formal consensus development informed by systematic evidence reviews. They rated the appropriateness of referral for 108 case scenarios describing patients according to symptom severity, age, body mass, co-morbidity and referral preference. Appropriateness was expressed on scale from 1 (‘strongly disagree’) to 9 (‘strongly agree’). Results. Ratings of referral appropriateness were strongly influenced by symptom severity and patients' referral preferences. The influence of other patient characteristics was small. There was consensus that patients with severe knee symptoms who want to be referred should be referred and that patient with moderate or mild symptoms and strong preference against referral should not be referred. Referral preference had a greater impact on the ratings of referral appropriateness when symptoms were moderate or severe than when symptoms were mild. Conclusions. Referral decisions for patients with osteoarthritis of the knee should only be guided by symptom severity and patients' referral preferences. The guideline development group seemed to have given priority to avoiding inefficient resource use in patients with mild symptoms and to respecting patient autonomy in patients with severe symptoms.

To identify the impact of body mass index (BMI) and Western advertising and media on the stage of the nutrition transition among Jordanian women, and to evaluate their impact on eating styles and body image. A randomised cross-sectional survey that included a variety of culturally measured Likert-type scales and body size images. In addition, BMI was calculated based on measured height and weight. In the homes of the participants. The data were collected by female interviewers who worked for the Jordan Department of Statistics. The sample was based on a random and representative selection of 800 mostly urban Jordanian women. A pre-test sample of 100 women was also used to validate the instruments. Women tended to agree that they ate based on emotional cues. They had high levels of disordered eating attitudes and behaviours and 42.1% were considered restrained eaters. However, these women also had higher than expected body esteem levels and desired a healthy body size. As expected, being obese was associated with a desire to lose weight, being a restrained and emotional eater, and having more disordered eating attitudes and behaviours. Similarly, Western advertising and media were associated with restrained and emotional eating, desired weight loss, and disordered eating attitudes and behaviours. There is a need to develop health education materials that explain the influence of obesity on health and the negative psychological and physical consequences of restrained and emotional eating, building on the current cultural preferences of healthy body size. Further implications and suggestions for future research are discussed.

Full Text Available Abstract Background Numerous studies examined factors in promoting a patient preference for active participation in treatment decision making with only modest success. The purpose of this study was to identify types of patients wishing to participate in treatment decisions as well as those wishing to play a completely active or passive role based on a Germany-wide survey of dialysis patients; using a prediction typal analysis method that defines types as configurations of categories belonging to different attributes and takes particularly higher order interactions between variables into account. Methods After randomly splitting the original patient sample into two halves, an exploratory prediction configural frequency analysis (CFA was performed on one-half of the sample (n = 1969 and the identified types were considered as hypotheses for an inferential prediction CFA for the second half (n = 1914. 144 possible prediction types were tested by using five predictor variables and control preferences as criterion. An α-adjustment (0.05 for multiple testing was performed by the Holm procedure. Results 21 possible prediction types were identified as hypotheses in the exploratory prediction CFA; four patient types were confirmed in the confirmatory prediction CFA: patients preferring a passive role show low information seeking preference, above average trust in their physician, perceive their physician's participatory decision-making (PDM-style positive, have a lower educational level, and are 56-75 years old (Type 1; p 76 years old (Type 2; p p p Conclusions The method prediction configural frequency analysis was newly introduced to the research field of patient participation and could demonstrate how a particular control preference role is determined by an association of five variables.

Human vocal attractiveness as signaled by body size projection.

Directory of Open Access Journals (Sweden)

Yi Xu

Full Text Available Voice, as a secondary sexual characteristic, is known to affect the perceived attractiveness of human individuals. But the underlying mechanism of vocal attractiveness has remained unclear. Here, we presented human listeners with acoustically altered natural sentences and fully synthetic sentences with systematically manipulated pitch, formants and voice quality based on a principle of body size projection reported for animal calls and emotional human vocal expressions. The results show that male listeners preferred a female voice that signals a small body size, with relatively high pitch, wide formant dispersion and breathy voice, while female listeners preferred a male voice that signals a large body size with low pitch and narrow formant dispersion. Interestingly, however, male vocal attractiveness was also enhanced by breathiness, which presumably softened the aggressiveness associated with a large body size. These results, together with the additional finding that the same vocal dimensions also affect emotion judgment, indicate that humans still employ a vocal interaction strategy used in animal calls despite the development of complex language.

Elevational variation in body-temperature response to immune challenge in a lizard

Full Text Available Immunocompetence benefits animal fitness by combating pathogens, but also entails some costs. One of its main components is fever, which in ectotherms involves two main types of costs: energy expenditure and predation risk. Whenever those costs of fever outweigh its benefits, ectotherms are expected not to develop fever, or even to show hypothermia, reducing costs of thermoregulation and diverting the energy saved to other components of the immune system. Environmental thermal quality, and therefore the thermoregulation cost/benefit balance, varies geographically. Hence, we hypothesize that, in alpine habitats, immune-challenged ectotherms should show no thermal response, given that (1 hypothermia would be very costly, as the temporal window for reproduction is extremely small, and (2 fever would have a prohibitive cost, as heat acquisition is limited in such habitat. However, in temperate habitats, immune-challenged ectotherms might show a febrile response, due to lower cost/benefit balance as a consequence of a more suitable thermal environment. We tested this hypothesis in Psammodromus algirus lizards from Sierra Nevada (SE Spain, by testing body temperature preferred by alpine and non-alpine lizards, before and after activating their immune system with a typical innocuous pyrogen. Surprisingly, non-alpine lizards responded to immune challenge by decreasing preferential body-temperature, presumably allowing them to save energy and reduce exposure to predators. On the contrary, as predicted, immune-challenged alpine lizards maintained their body-temperature preferences. These results match with increased costs of no thermoregulation with elevation, due to the reduced window of time for reproduction in alpine environment.

Pires, Carla Maria Batista Ferreira; Cavaco, Afonso

2018-03-01

Only recently, regulations on the names of medicines were developed. Regulations are mainly focused on avoiding the approval of medicine names that may be confusing to others. Furthermore, legal requirements do not include testing for human factors, such as potential users' preferences. To develop a set of new brand names of medicines, to determine subjects' preferred names, and to evaluate if the linguistic features of these names were related to subjects' preferences. Forty-six new names linguistically equivalent to the Portuguese brand names of medicines were developed. A panel of 13 postgraduates on linguistic studies were purposively enrolled. Participants were required to select and categorize the 6 most preferred names. From the 29 selected names: 62.1% ended in consonants, 65.5% contained at least one syllable of the CVC type, and 62.1% presented final stress. Considering these 3 linguistic features, there were statistically significant differences between the preferred and underpreferred names: χ 2 = 4.572, P = .032; χ 2 = 5.599, P = .018; and χ 2 = 4.572; P = .032, respectively. Some linguistic features of the evaluated names were related to subjects' preferences. Tests on subjects' preferences about the names of medicines may provide additional safety features addressed by the present regulations.

Collective animal decisions: preference conflict and decision accuracy.

Science.gov (United States)

Conradt, Larissa

2013-12-06

Social animals frequently share decisions that involve uncertainty and conflict. It has been suggested that conflict can enhance decision accuracy. In order to judge the practical relevance of such a suggestion, it is necessary to explore how general such findings are. Using a model, I examine whether conflicts between animals in a group with respect to preferences for avoiding false positives versus avoiding false negatives could, in principle, enhance the accuracy of collective decisions. I found that decision accuracy nearly always peaked when there was maximum conflict in groups in which individuals had different preferences. However, groups with no preferences were usually even more accurate. Furthermore, a relatively slight skew towards more animals with a preference for avoiding false negatives decreased the rate of expected false negatives versus false positives considerably (and vice versa), while resulting in only a small loss of decision accuracy. I conclude that in ecological situations in which decision accuracy is crucial for fitness and survival, animals cannot 'afford' preferences with respect to avoiding false positives versus false negatives. When decision accuracy is less crucial, animals might have such preferences. A slight skew in the number of animals with different preferences will result in the group avoiding that type of error more that the majority of group members prefers to avoid. The model also indicated that knowing the average success rate ('base rate') of a decision option can be very misleading, and that animals should ignore such base rates unless further information is available.

OBJECTIVE The cortisol-regenerating enzyme 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) amplifies glucocorticoid levels in liver and adipose tissue. 11β-HSD1 inhibitors are being developed to treat type 2 diabetes. In obesity, 11β-HSD1 is increased in adipose tissue but decreased in liver. The benefits of pharmacological inhibition may be reduced if hepatic 11β-HSD1 is similarly decreased in obese patients with type 2 diabetes. To examine this, we quantified in vivo whole-body, splanchnic, and hepatic 11β-HSD1 activity in obese type 2 diabetic subjects. RESEARCH DESIGN AND METHODS Ten obese men with type 2 diabetes and seven normal-weight control subjects were infused with 9,11,12,12-[2H]4cortisol (40%) and cortisol (60%) at 1.74 mg/h. Adrenal cortisol secretion was suppressed with dexamethasone. Samples were obtained from the hepatic vein and an arterialized hand vein at steady state and after oral administration of cortisone (5 mg) to estimate whole-body and liver 11β-HSD1 activity using tracer dilution. RESULTS In obese type 2 diabetic subjects, the appearance rate of 9,12,12-[2H]3cortisol in arterialized blood was increased (35 ± 2 vs. 29 ± 1 nmol/min, P cortisol production was not reduced (29 ± 6 vs. 29 ± 6 nmol/min), and cortisol appearance in the hepatic vein after oral cortisone was unchanged. CONCLUSIONS Whole-body 11β-HSD1 activity is increased in obese men with type 2 diabetes, whereas liver 11β-HSD1 activity is sustained, unlike in euglycemic obesity. This supports the concept that inhibitors of 11β-HSD1 are likely to be most effective in obese type 2 diabetic subjects. PMID:21266326

Astronauts' orientation preferences tend to correlate with their susceptibility to space motion sickness (SMS). Orientation preferences appear universally, since variable sensory cue priorities are used between individuals. However, SMS susceptibility changes after proper training, while orientation preferences seem to be intrinsic proclivities. The present study was conducted to investigate whether orientation preferences change if susceptibility is reduced after repeated exposure to a virtual reality (VR) stimulus environment that induces SMS. A horizontal supine posture was chosen to create a sensory context similar to weightlessness, and two VR devices were used to produce a highly immersive virtual scene. Subjects were randomly allocated to an experimental group (trained through exposure to a provocative rotating virtual scene) and a control group (untrained). All subjects' orientation preferences were measured twice with the same interval, but the experimental group was trained three times during the interval, while the control group was not. Trained subjects were less susceptible to SMS, with symptom scores reduced by 40%. Compared with untrained subjects, trained subjects' orientation preferences were significantly different between pre- and posttraining assessments. Trained subjects depended less on visual cues, whereas few subjects demonstrated the opposite tendency. Results suggest that visual information may be inefficient and unreliable for body orientation and stabilization in a rotating visual scene, while reprioritizing preferences for different sensory cues was dynamic and asymmetric between individuals. The present findings should facilitate customization of efficient and proper training for astronauts with different sensory prioritization preferences and dynamic characteristics.Chen W, Chao J-G, Zhang Y, Wang J-K, Chen X-W, Tan C.

Theories of embodied conceptual meaning suggest fundamental relations between others' actions, language, and our own actions and visual attention processes. Prior studies have found that when people view an image of a neutral body in a scene they first look toward, in order, the head, torso, hands, and legs. Other studies show associations between action verbs and the body-effectors used in performing the action (e.g., "jump" with feet/legs; "talk" with face/head). In the present experiment, the visual attention of participants was recorded with a remote eye-tracking system while they viewed an image of an actor pantomiming an action and heard a concrete action verb. Participants manually responded whether or not the action image was a good example of the verb they heard. The eye-tracking results confirmed that participants looked at the head most, followed by the hands, and the feet least of all; however, visual attention to each of the body-parts also varied as a function of the effector associated with the spoken verb on image/verb congruent trials, particularly for verbs associated with the legs. Overall, these results suggest that language influences some perceptual processes; however, hearing auditory verbs did not alter the previously reported fundamental hierarchical sequence of directed attention, and fixations on specific body-effectors may not be essential for verb comprehension as peripheral visual cues may be sufficient to perform the task.

Full Text Available Context: Various studies have focused on the correlation between β2-adrenergic receptor (β2AR, the β3-adrenergic receptor (β3AR, and the uncoupling protein 1 (UCP1 polymorphisms and obesity in patients with type 2 diabetes mellitus (T2DM. Aims: We examined the correlation between these polymorphisms and body composition variables and between body composition and lifestyle variables in Japanese T2DM patients. Materials and Methods: Of the 48, T2DM outpatients in Kanagawa prefecture recruited for participation, 32 (6 men and 26 women met the study criteria and were enrolled. Obesity-related gene polymorphisms were identified in 3 genes β3AR, UCP1, and β2AR using the SMart amplification process. Body composition variables were measured using a body composition analyzer. Data regarding food and nutrient consumption, family history, and lifestyle factors were collected via administration of questionnaires. Results: Because significant differences in body composition variables were found between men and women, statistical analysis was performed with data from the 25 female subjects only. On the basis of results of genetic testing, the subjects were divided into genotype groups for two-group and three-group comparison. The β3AR, UCP1, and β2AR polymorphisms and body composition significantly correlated with the percentage of subcutaneous fat in both arms as compared with the wild type or hetero groups with β3AR polymorphisms. However, physical activity correlated with several body composition variables. Conclusions: These results suggest that obesity in T2DM patients is not the result of presence of an obesity-related gene polymorphism but rather the absence of daily physical activity.

LEPTIN RESISTANCE AND TYPE 2 DIABETES

Directory of Open Access Journals (Sweden)

O. M. Oleshchuk

2017-07-01

Full Text Available Leptin is one of adipocyte-secreted hormones. It signals to the brain and other tissues about the status of body energy reserves. Circulating leptin levels are directly proportional to the amount of the body fat. Leptin concentration increases when surfeit and decreases during fasting. Obese patients are hyperleptinemic compared with thin persons and they are tolerant to the central hypothalamic effects of leptin. The reduced sensitivity toward exogenous and endogenous leptin is commonly referred to as leptin resistance. Alterations in the signaling of the long isoform of the leptin receptor play the crucial role in leptin resistance. Surfeit may induce leptin resistance and other metabolic sequelae of obesity. Leptin insensitivity and insulin resistance play a major role in the development of type 2 diabetes. Metformin remains the preferred first-line pharmacologic agent for the treatment of type 2 diabetes. It reduces hepatic glucose production, increases glucose uptake in peripheral tissue and can lead to weight loss. Metformin decreases both insulin and leptin concentration, restores the sensitivity to these hormones. But some studies have shown poor relationship between metformin action and leptin level. And the mechanism of metformin action on leptin resistance remains unclear. Thus, these issues should be studied as well as polymorphisms in genes encoding metformin action.

Science choices and preferences of middle and secondary school students in Utah

Baird, J. Hugh; Lazarowitz, Reuven; Allman, Verl

This research sought to answer two questions: (1) What are Utah junior and senior high school students' preferences and choices regarding science subjects? (2) Could preferences and choices be related to the type of school, age or gender? Two thousand students from grades six through twelve participated in this study. Findings show that zoology and human anatomy and physiology were most preferred. Ecology was least prefered. Topics in the physical sciences were also low. There was a trend among girls to prefer natural sciences such as botany while boys tended to prefer the physical sciences. Generally, students' choices were limited to those subjects presently taught in the formal school curriculum. They appeared unaware of the many science related subjects outside the texts or the approved course of study.

Cell Type Preference of a Novel Human Derived Cell-Permeable Peptide dNP2 and TAT in Murine Splenic Immune Cells.

Sangho Lim

Full Text Available Cell-permeable peptides (CPPs have been widely studied as an attractive drug delivery system to deliver therapeutic macromolecules such as DNA, RNA, and protein into cells. However, its clinical application is still limited and controversial due to the lack of a complete understanding of delivery efficiency in target cells. Previously we identified and characterized the novel and superior CPP, named dNP2, and here we comparatively analyzed intracellular delivery efficiency of dNP2 and TAT in various immune cells of mouse spleen to demonstrate their cell type preference. dNP2- or TAT-conjugated fluorescent proteins were most efficiently taken up by phagocytic cells such as dendritic cells and macrophages while little protein uptake was seen by lymphocytes including T cells, B cells, and NK cells. Interestingly CD8+ lymphoid dendritic cells and CD62LloCD44hi memory like T cell subsets showed significantly better uptake efficiency in vitro and in vivo relative to other dendritic cells or T cells, respectively. In addition, activated macrophages, T cells, and B cells took up the proteins more efficiently relative to when in the resting state. Importantly, only dNP2, not TAT, shows significant intracellular protein delivery efficiency in vivo. Collectively, this study provides important information regarding heterogeneous intracellular delivery efficiency of CPPs such as dNP2 and TAT with cell type preference in the spleen needed for its application in phagocytic cells or activated immune cells.

Full Text Available Background : Dapagliflozin, a sodium-glucose cotransporter-2 inhibitor, reduces hyperglycemia and body weight by inhibiting renal glucose reabsorption. However, only a few studies have demonstrated efficacy of dapagliflozin for type 2 diabetic patients in Korea. We evaluated the efficacy and safety of dapagliflozin for Korean type 2 diabetes patients. Methods : This is a retrospective study that included data from 61 patients who received 12 months of dapagliflozin therapy and who visited a single medical center between January 2015 and July 2016. Patients were separated into three groups: dual combination of dapagliflozin and metformin, triple combination of dapagliflozin and metformin with sulfonylurea, or dipeptidyl peptidase IV inhibitors, and quadriple combination of dapagliflozin, metformin, and sulfonylurea with dipeptidyl peptidase IV inhibitors. Patients who achieved ≥5% body weight reduction were classified as responders, and those who achieved <5% body weight reduction were classified as non-responders. Results : After 12 months, the mean change from baseline body weight was -3.4±2.6 kg (P<0.001 for all patients, -3.4±3.1 kg (P<0.001 for group 1, -2.7±2.0 kg (P=0.008 for group 2, and -4.0±2.3 kg (P<0.001 for group 3. Fasting C-peptide level was higher in the responder group than in the non-responder group (3.25±1.07 ng/mL vs. 2.62±1.02 ng/mL, P=0.023. In total, reductions in HbA1c, PP2, and FPG levels were -0.61±0.82% (P=0.000, -35.4±62 mg/dL (P=0.000, and -21.3±56.2 mg/dL (P=0.012, respectively. They had mild adverse events included orthostatic dizziness and urinary tract infection. Conclusion : SGLT2 inhibitor improved glycemic control and reduced body weight in a safe manner for patients with type 2 diabetes mellitus.

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.

Deal sites are widely used for some time and there is a growing body of knowledge on them. There exists literature on infomediaries. But there is a gap when it comes to infomediaties focused on deal sites, i.e. aggregators of deal site offers. The research focused on impact of Big Five Inventory...... personality traits on whether respondents prefer visiting individual deal sites, or aggregators, or they do not have any preference and visit both. Gender was used as a control variable. With regards, to the results, conscientiousness agreeableness, and openness to experi-ence influence the preference. Higher...... the values of all three variables, more likely it is that a person prefers aggregators....

Left and right brain-oriented hemisity subjects show opposite behavioral preferences.

Recently, three independent, intercorrelated biophysical measures have provided the first quantitative measures of a binary form of behavioral laterality called "Hemisity," a term referring to inherent opposite right or left brain-oriented differences in thinking and behavioral styles. Crucially, the right or left brain-orientation of individuals assessed by these methods was later found to be essentially congruent with the thicker side of their ventral gyrus of the anterior cingulate cortex (vgACC) as revealed by a 3 min MRI procedure. Laterality of this putative executive structural element has thus become the primary standard defining individual hemisity. Here, the behavior of 150 subjects, whose hemisity had been calibrated by MRI, was assessed using five MRI-calibrated preference questionnaires, two of which were new. Right and left brain-oriented subjects selected opposite answers (p > 0.05) for 47 of the 107 "either-or," forced choice type preference questionnaire items. The resulting 30 hemisity subtype preference differences were present in several areas. These were: (1) in logical orientation, (2) in type of consciousness, (3) in fear level and sensitivity, (4) in social-professional orientation, and (5) in pair bonding-spousal dominance style. The right and left brain-oriented hemisity subtype subjects, sorted on the anatomical basis of upon which brain side their vgACC was thickest, showed 30 significant differences in their "either-or" type of behavioral preferences.

Food preference is one of the important information that can be used to know the food chain in order to manage fisheries resources. This study aims to determine the food habits and preference of red devil (Amphilophus labiatus) in the Sermo Reservoir, Kulon Progo Regency. Samples were collected randomly each month from September 2013 to February 2014. Each sample collected was measured its total length, body weight, and determined sex, then dissected to measure the gut length and to observe gut contents. Results showed that red devil is omnivorous (relative gut length = 3.83) with food composition consisted of fish, crustaceans, detritus, phytoplankton, zooplankton, plants, insects, insect’s larvae, Chironomus sp., and annelids. A change occurred in the food preference of red devil, i.e. the young fish prefers to feed Chironomus sp. larvae (86.02 %) whereas the adult fish prefers fish/fish chunk (81.82 %). Trophic level status of red devil showed as carnivorous and niche overlapping between male and female of the adult.

It is well known that obesity is a major risk factor for type 2 diabetes (T2D), while exercise is known to reduce body fatness and attenuate the risk of T2D. The aim of this chapter is to examine the interactions between exercise, obesity and body fat distribution, and the risk for T2D. Firstly, we show that body fatness, in particular visceral adipose tissue (VAT) accumulation, is associated with insulin resistance and incident T2D. We then show that aerobic exercise of sufficient intensity and volume results in a decrease in body fat and VAT. Conversely, sedentary behavior and physical inactivity are associated with increased body fat and VAT. Finally, the chapter examines the interaction between physical activity (PA), obesity and risk for T2D and shows that both obesity and PA are significant independent predictors of incident T2D, but the magnitude of risk imparted by high levels of body fat is much greater than that of low levels of PA. Further, we show that obese physically active individuals are at greater risk for incident T2D than normal-weight physically inactive individuals. The mechanisms underlying this complex interaction include the ability of exercise to increase free fatty acid oxidation to match high rates of lipolysis associated with obesity, as well as the effects of exercise on adipokine, cytokine and myokine secretion. Exercise, of sufficient volume and intensity, is therefore recommended to reduce obesity, centralization of body fat, and risk of T2D.

On the evolutionary origins of differences in sexual preferences

Directory of Open Access Journals (Sweden)

Daniil eRyabko

2015-05-01

Full Text Available A novel general explanation of the evolutionary process leading to the appearance of differences insexual preferences is proposed. The explanation is fully general: it is not specific to any particular type of sexual preferences, nor to any species orpopulation. It shows how different sexual preferences can appear in any large group-living population in which sexual selection is sufficiently strong in each sex. The main idea is that the lack of interest towards a member of the opposite sex may be interpreted as a signal of popularity, and thus a sign of reproductive success. It is then boosted by the Fisher runaway process, resulting in a generalized trait~--- lack of interest towards the opposite sex. This trait develops far beyond the point when it gives a reproductive disadvantage, resulting in well-pronounced different sexual preferences. This hypothesis is placed into the context of other works on different sexual preferences in animals; supporting evidence from the literature is reviewed and additional research needed to confirm or refute the hypothesis in any given species is outlined.

NMDA receptors in mouse anterior piriform cortex initialize early odor preference learning and L-type calcium channels engage for long-term memory.

The interactions of L-type calcium channels (LTCCs) and NMDA receptors (NMDARs) in memories are poorly understood. Here we investigated the specific roles of anterior piriform cortex (aPC) LTCCs and NMDARs in early odor preference memory in mice. Using calcium imaging in aPC slices, LTCC activation was shown to be dependent on NMDAR activation. Either D-APV (NMDAR antagonist) or nifedipine (LTCC antagonist) reduced somatic calcium transients in pyramidal cells evoked by lateral olfactory tract stimulation. However, nifedipine did not further reduce calcium in the presence of D-APV. In mice that underwent early odor preference training, blocking NMDARs in the aPC prevented short-term (3 hr) and long-term (24 hr) odor preference memory, and both memories were rescued when BayK-8644 (LTCC agonist) was co-infused. However, activating LTCCs in the absence of NMDARs resulted in loss of discrimination between the conditioned odor and a similar odor mixture at 3 hr. Elevated synaptic AMPAR expression at 3 hr was prevented by D-APV infusion but restored when LTCCs were directly activated, mirroring the behavioral outcomes. Blocking LTCCs prevented 24 hr memory and spared 3 hr memory. These results suggest that NMDARs mediate stimulus-specific encoding of odor memory while LTCCs mediate intracellular signaling leading to long-term memory.

To explore the relationship between weight status in early adulthood and body weight change at middle age in adults and type 2 diabetes mellitus (T2DM). The data of 14 population samples from China Multicenter Collaborative Study of Cardiovascular Epidemiology conducted in 1998 were used. Approximately 1 000 men and women in each sample were surveyed for cardiovascular disease risk factors, including body weight at age 25 years. The body mass index (BMI) at the age 25 years was calculated. The association between body weight in early adulthood and body weight change at middle age and T2DM was examined by using logistic regression model. The incidence of T2DM in low weight group (BMIweight group (BMI: 18.5-23.9 kg/m(2)), overweight group (BMI: 24.0-27.9 kg/m(2)) and obese group (BMI:≥28.0 kg/m(2)) at 25 years old were 2.4%(30/1263), 2.8%(266/9562), 4.0%(70/1739) and 6.4% (7/110), respectively (P value for trendincidence of T2DM for adults with weight change 12.5 kg at middle age were 2.5% (18/712), 1.3%(21/1629), 2.1%(48/2330), 2.3%(59/2585), 3.7%(94/2518), and 4.6% (133/2900) respectively. (P value for trend weight gain were positively correlated with T2DM after adjusted other risk factors (all P values for trend weight gain at middle age were both independently associated with the increased risk of T2DM in middle-aged men and women.

Purpose: There are multiple current strategies for breast radiotherapy (RT). The alignment of physician practice patterns with best evidence and patient preferences will enhance patient autonomy and improve cancer care. However, there is little information describing patient preferences for breast RT and physician practice patterns. Methods and Materials: Using a reliable and valid instrument, we assessed the preferences of 5,000 randomly selected women (with or without cancer) undergoing mammography. To assess practice patterns, 2,150 randomly selected physician-members of American Society for Radiation Oncology were surveyed. Results: A total of 1,807 women (36%) and 363 physicians (17%) provided usable responses. The 95% confidence interval is < ±2.3% for patients and < ±5.3% for physicians. Patient preferences were hypofractionated whole breast irradiation (HF-WBI) 62%, partial breast irradiation (PBI) 28%, and conventionally fractionated whole breast irradiation (CF-WBI) 10%. By comparison, 82% of physicians use CF-WBI for more than 2/3 of women and 56% never use HF-WBI. With respect to PBI, 62% of women preferred three-dimensional (3D)-PBI and 38% favor brachytherapy-PBI, whereas 36% of physicians offer 3D-PBI and 66% offer brachytherapy-PBI. 70% of women prefer once-daily RT over 10 days vs. twice-daily RT over 5 days. 55% of physicians who use PBI do not offer PBI on clinical trial. Conclusions: HF-WBI, while preferred by patients and supported by evidence, falls behind the unproven and less preferred strategy of PBI in clinical practice. There is a discrepancy between women’s preferences for PBI modality and type of PBI offered by physicians. Further alignment is needed between practice patterns, patient preferences, and clinical evidence.

Food preferences and mound-building behaviour of the mound-building mice Mus spicilegus

Optimal foraging strategies and food choice are influenced by various factors, e.g. availability, size and caloric content of the food type and predation risk. However, food choice criteria may change when food is not eaten immediately but has to be carried to a storage site for later use. For example, handling time in terms of harvesting and transport time should be optimized, particularly when the risk of predation is high. Thus, it is not clear whether food selected by hoarding animals reflects their food preference due to intrinsic features of the food type, e.g. size, caloric or lipid content, or whether the food type selected is a compromise that also considers the handling time required for harvesting and transport. We investigate this question in relation to food hoarding behaviour in mound-building mice. In autumn, mound-building mice Mus spicilegus collect seeds and other plant material and cover it with soil. Such above-ground storage is quite unusual for rodents. Here, we investigated whether there is a relationship between the seed species preferred as building materials and those preferred for food. We conducted a seed preference test using three most collected weed species for mound building. Controlling factors like food availability or predation risk, mice prefer Setaria spp. as food, although Amaranthus spp. and Chenopodium spp. were preferentially harvested and stored. By including the availability of the three species, our experimental results were confirmed, namely, a clear preference for Setaria spp. Also, handling time and seed size revealed to influence plant choice.

Site preference of Mg acceptors and improvement of p-type doping efficiency in nitride alloys.

Park, Ji-Sang; Chang, K J

We perform first-principles density functional calculations to investigate the effect of Al and In on the formation energy and acceptor level of Mg in group-III nitride alloys. Our calculations reveal a tendency for the Mg dopants to prefer to occupy the lattice sites surrounded with Al atoms, whereas hole carriers are generated in In- or Ga-rich sites. The separation of the Mg dopants and hole carriers is energetically more favourable than a random distribution of dopants, being attributed to the local bonding effect of weak In and strong Al potentials in alloys. As a consequence, the Mg acceptor level, which represents the activation energy of Mg, tends to decrease with increasing numbers of Al next-nearest neighbours, whereas it increases as the number of In next-nearest neighbours increases. Based on the results, we suggest that the incorporation of higher Al and lower In compositions will improve the p-type doping efficiency in quaternary alloys, in comparison with GaN or AlGaN ternary alloys with similar band gaps.

Effect of Antenna Type on the Capacity of Body-to-Body Capacity When Using Uniform Power Allocation

Body-area networks are led to target multimedia applications where high-data rate is involved. In this paper, the characterization of the measured body-to-body channels and the ergodic capacity with uniform power allocation is discussed when using multiple-input multiple-output (MIMO) PIFA and IFA antenna systems. This capacity is compared to the measured belt-head and belt-chest on-body channels using PIFA antennas in the same environment. It is shown that body channels reach less ergodic capacity than the equivalent Rayleigh channel because of the presence of a LOS component. The capacity is the same for the body-to-body case regardless of the antenna and the on-body channels reach better capacity values compared to these former. © 2012 IEEE.

The present study aimed to compare body dissatisfaction, food choices, physical activity and weight-management practices by gender and school type. A questionnaire was used to obtain height, weight, body image perception using Stunkard's figure rating scale, food choices, physical activity and weight-management practices. Nine single- and mixed-gender schools located in Bangkok Metropolitan Region, Thailand. Students in 10th-12th grade, aged 15-18 years (n 2082). Only 18% of females and 21% of males did not indicate body dissatisfaction. About 66% of females selected a thinner ideal figure than their current figure. Among males, 44% wanted a thinner figure, but 35% wanted a bigger figure. However, univariate analysis found differences by school type but not gender in the degree of body dissatisfaction; students in single-gender schools had more body dissatisfaction. Females reported using more weight-management practices but less physical activity, while males reported healthier food choices. Participants in single-gender schools had healthier food choices compared with those in mixed-gender schools. Adolescents who were at increased risk of a greater degree of body dissatisfaction were females, attended single-gender schools, had lower household income, higher BMI and less physical activity. Most participants reported being dissatisfied with their current body shape, but the type and level of dissatisfaction and use of weight-management practices differed by gender and type of school. These findings suggest that programmes to combat body dissatisfaction should address different risk factors in males and females attending single- and mixed-gender schools.

Card-sorting tasks for assessing food and activity preferences and patterns among African American girls were developed. Associations among food preference and intake frequency, activity preference and frequency, and body mass index were examined. Participants completed newly developed card-sorting tasks assessing food and activity preferences and patterns. Height and weight were measured. Ninety-six 8- to 10-year-old African American girls from schools and community centers in Minneapolis-St. Paul. Preference and frequency data for 64 foods/beverages and 34 activities. Frequencies for food and activity preference and frequency categories were computed. Pearson correlations among food and activity preference, frequency, and body mass index were computed. High-sugar (eg, fruit drinks, soda) and/or high-fat (eg, ice cream, cookies) foods were among the most popular and frequently consumed. Ninety-six percent of girls liked fruit drinks, with 35% consuming them "almost every day." Less-structured activities such as biking, games, jump rope, and dance were most popular. Biking was preferred by 85% of girls, with 48% biking "almost every day." Food preference and frequency categories were moderately correlated (r=0.30 to 0.58), as were activity preference and frequency (r=0.37 to 0.49). The card-sorting tasks are useful tools for assessing food and activity preferences and patterns in girls. Obesity prevention programs for African American girls should include preferred activities such as dance, jump rope, and active play. Programs may also benefit from a focus on replacing high fat/high sugar snacks and sweetened beverages with low-fat, lower-calorie snacks and beverages (eg, fruit, vegetables, water).

Factors Influencing Parents' Preferences and Parents' Perceptions of Child Preferences of Picturebooks

Wagner, Laura

2017-01-01

This study examined factors influencing parents' preferences and their perceptions of their children's preferences for picturebooks. First, a content analysis was conducted on a set of picturebooks (N = 87) drawn from the sample described in Wagner (2013); Then, parents (N = 149) rated the books and several content properties were examined for their ability to predict parents' preferences and their perception of their children's preferences. The initial content analysis found correlated clusters of disparate measures of complexity (linguistic, cognitive, narrative) and identified a distinctive sub-genre of modern books featuring female protagonists. The experimental preference analysis found that parents' own preferences were most influenced by the books' age and status; parents' perceptions of their children's preferences were influenced by gender, with parents perceiving their sons (but not daughters) as dis-preferring books with female protagnoists. In addition, influences of the child's reading ability and the linguistic complexity of the book on preferences suggested a sensitivity to the cultural practice of joint book-reading. PMID:28919869

Boys or girls? Parents' preferences and sex control.

Science.gov (United States)

Williamson, N E

1978-01-01

Recent evidence from the U.S. and from other selected countries is examined on parent sex preferences for their children and how strongly these are held. This involves the significance of these preferences, the social and economic conditions that foster different types of preferences, and how different individuals and societies deal with them. The traditional preference for boys appears to remain nearly universal, which runs contrary to the ideal of "every child a wanted child," and also presents an obstacle to desired declines in fertility in developing countries where sons are still perceived as needed for economic and emotional security. This tendency has been turned around in Japan, Singapore, Hong Kong, and the U.S., where small families are now the ideal. 3 basic approaches to the scientific selection of sex-specific sperm for preselection, the timing of sexual intercourse, the separation of male- and female-bearing sperm followed by artificial insemination, and selective abortion after fetal sex determination indicate that an effective and practical method of sex control is still further off than predicted.

Type 2 diabetes is the most common metabolic disorder worldwide. Traditional herbs and spices can be used to control blood glucose concentrations. The objective of this study was to evaluate the effects of the daily intake of three grams cinnamon over eight weeks on glycemic status, lipid profiles and body composition in type 2 diabetic patients. A double blind, randomized, placebo controlled clinical trial was conducted on 44 patients with type 2 diabetes. Participants were randomly assigned to take either a three g/day cinnamon supplement (n=22) or a placebo (n=22) for eight weeks. Weight, height, body fat mass and systolic and diastolic blood pressure were measured at baseline and after intervention. The fasting blood glucose, insulin, HbA1c, total cholesterol, LDL C, HDL C, Apo lipoprotein A I and B were measured at baseline and endpoint. From 44 subjects participated in this study 37 completed the study. There were no significant differences in baseline characteristics, dietary intake and physical activity between groups. In the treatment group, the levels of fasting blood glucose, HbA1c, triglyceride, weight, BMI and body fat mass decreased significantly compared to baseline, but not in placebo group. No significant differences were observed in glycemic status indicators, lipid profile and anthropometric indicators between the groups at the end of intervention. These data suggest that cinnamon may have a moderate effect in improving glycemic status indicators.

Take me where I want to go: Institutional prestige, advisor sponsorship, and academic career placement preferences.

Full Text Available Placement in prestigious research institutions for STEM (science, technology, engineering, and mathematics PhD recipients is generally considered to be optimal. Yet some doctoral recipients are not interested in intensive research careers and instead seek alternative careers, outside but also within academe (for example teaching positions in Liberal Arts Schools. Recent attention to non-academic pathways has expanded our understanding of alternative PhD careers. However, career preferences and placements are also nuanced along the academic pathway. Existing research on academic careers (mostly research-centric has found that certain factors have a significant impact on the prestige of both the institutional placement and the salary of PhD recipients. We understand less, however, about the functioning of career preferences and related placements outside of the top academic research institutions. Our work builds on prior studies of academic career placement to explore the impact that prestige of PhD-granting institution, advisor involvement, and cultural capital have on the extent to which STEM PhDs are placed in their preferred academic institution types.

Placement in prestigious research institutions for STEM (science, technology, engineering, and mathematics) PhD recipients is generally considered to be optimal. Yet some doctoral recipients are not interested in intensive research careers and instead seek alternative careers, outside but also within academe (for example teaching positions in Liberal Arts Schools). Recent attention to non-academic pathways has expanded our understanding of alternative PhD careers. However, career preferences and placements are also nuanced along the academic pathway. Existing research on academic careers (mostly research-centric) has found that certain factors have a significant impact on the prestige of both the institutional placement and the salary of PhD recipients. We understand less, however, about the functioning of career preferences and related placements outside of the top academic research institutions. Our work builds on prior studies of academic career placement to explore the impact that prestige of PhD-granting institution, advisor involvement, and cultural capital have on the extent to which STEM PhDs are placed in their preferred academic institution types.

We take as a starting point that longevity has a significant impact on furthering sustainability in textiles and clothing since it can be a driver on many levels, e.g. new business models, decisions made in the design phase and/or changes in use and consumption. The study applies variations...... of the Repertory Grid technique and Wardrobe Studies to frame a tangible dialogue enabling the parents to elaborate on personal preferences of design aesthetics and materials in baby clothing. In the analysis we use the body stocking as a common reference point for learning about reasons for high use frequency....... In addition, it is exemplified how personal taste, preferences for aesthetics and experience of wellbeing may have an impact on high use frequency. Finally, the paper points to further elaboration by suggesting a (tentative) matrix structure to better understand the parameters in designing sustainable...

Dosha brain-types: A neural model of individual differences.

Travis, Frederick T; Wallace, Robert Keith

2015-01-01

This paper explores brain patterns associated with the three categories of regulatory principles of the body, mind, and behavior in Ayurveda, called Vata, Pitta, and Kapha dosha. A growing body of research has reported patterns of blood chemistry, genetic expression, physiological states, and chronic diseases associated with each dosha type. Since metabolic and growth factors are controlled by the nervous system, each dosha type should be associated with patterns of functioning of six major areas of the nervous system: The prefrontal cortex, the reticular activating system, the autonomic nervous system, the enteric nervous system, the limbic system, and the hypothalamus. For instance, the prefrontal cortex, which includes the anterior cingulate, ventral medial, and the dorsal lateral cortices, would exhibit a high range of functioning in the Vata brain-type leading to the possibility of being easily overstimulated. The Vata brain-type performs activity quickly. Learns quickly and forgets quickly. Their fast mind gives them an edge in creative problem solving. The Pitta brain-type reacts strongly to all challenges leading to purposeful and resolute actions. They never give up and are very dynamic and goal oriented. The Kapha brain-type is slow and steady leading to methodical thinking and action. They prefer routine and needs stimulation to get going. A model of dosha brain-types could provide a physiological foundation to understand individual differences. This model could help individualize treatment modalities to address different mental and physical dysfunctions. It also could explain differences in behavior seen in clinical as well as in normal populations.

In plant-pollinator networks, the floral morphology of food plants is an important determinant of the interaction niche of pollinators. Studies on foraging preferences of pollinators combining experimental and observational approaches may help to understand the mechanisms behind patterns of interactions and niche partitioning within pollinator communities. In this study, we tested whether morphological floral traits were associated with foraging preferences of hummingbirds for artificial and natural flower types in Costa Rica. We performed field experiments with artificial feeders, differing in length and curvature of flower types, to quantify the hummingbirds' interaction niche under unlimited nectar resources. To quantify the interaction niche under real-world conditions of limited nectar resources, we measured foraging preferences of hummingbirds for a total of 34 plant species. Artificial feeders were visited by Eupherusa nigriventris and Phaethornis guy in the pre-montane forest, and Lampornis calolaemus in the lower montane forest. Under experimental conditions, all three hummingbird species overlapped their interaction niches and showed a preference for the short artificial flower type over the long-straight and the long-curved flower types. Under natural conditions, the two co-occurring hummingbird species preferred to feed on plant species with floral traits corresponding to their bill morphology. The short-billed hummingbird E. nigriventris preferred to feed on short and straight flowers, whereas the long- and curved-billed P. guy preferred long and curved natural flowers. The medium-size billed species L. calolaemus preferred to feed on flowers of medium length and did not show preferences for plant species with specific corolla curvature. Our results show that floral morphological traits constrain access by short-billed hummingbird species to nectar resources. Morphological constraints, therefore, represent one important mechanism structuring trophic

From whom do older persons prefer support? The case of rural Thailand.

This study explores rural elderly preferences for support across a multi-dimensional measure of elderly care needs. Applying a framework developed in the U.S. to Thailand for the first time, five diverse types of support are considered: meal preparation, personal care, transportation, financial support, and emotional support. The emphasis is on preferences for care and not actual care received. The data are from focus group discussions conducted in seven villages in Nang Rong district, northeastern Thailand. Thailand and the study site represent the social and economic conditions faced by many rapidly industrializing places-where there has been a dramatic demographic transition (lowered fertility and substantial out-migration), growing numbers of older persons remaining in rural settings, and limited publically-financed elderly care or market-based elder care available for purchase. For this study, in each village, male and female older persons aged 60 and over participated in the focus group discussions. As part of the discussion, focus group participants were asked to rank their first four preferences by type of support. Male and female older persons' preferences were slightly different for genderized tasks. In addition, social closeness and geographical proximity mattered. Traditional matrilocal residence patterns contributed to the perceptions of the older persons. Neighbors were preferred when kin were not available. Preferences inform strategic choices by older persons given the context of available resources. Understanding preferences and strategic choices among the older persons can help policy makers tailor programs more effectively and efficiently, without jeopardizing elderly well-being.

Koizumi, Miwako; Cagniard, Barbara; Murphy, Niall P

2009-04-20

Previous studies show that the opioid peptide nociceptin stimulates food intake. Here, we studied nociceptin receptor knockout (NOP KO) mice in various behavioral paradigms designed to differentiate psychological and physiological loci at which endogenous nociceptin might control feeding. When presented a choice under food restriction, NOP KO mice displayed reduced preference for high sucrose diet, but lower intake of high fat diet under no-choice conditions. These responses were absent under ad libitum feeding conditions. Conditioned place preference to high fat diet under food-deprived conditions was unaltered in NOP KO mice, suggesting no difference in reward responses. Furthermore, operant food self-administration under a variety of conditions showed no genotype-dependent differences, suggesting no differences in the motivational properties of food. Taste reactivity to sucrose was unchanged in NOP KO mice, though NOP KO mice had altered aversive reactions to quinine solutions under ad libitum feeding, suggesting minor differences in the affective impact of palatable and unpalatable tastants. Although NOP KO mice re-fed following food-deprivation showed normal increases in plasma glucose and insulin, multidimensional scaling analysis showed that the relationship between these measures, body weight and plasma leptin was substantially disrupted in NOP KO, particularly in fasted mice. Additionally, the typical positive relationship between body weight and plasma leptin was considerably weaker in NOP KO mice. Together, these findings suggest that endogenous nociceptin differentially modulates diet preference depending on macronutrient content and homeostatic state, independently of the motivating, rewarding or orosensory properties of food, but may involve metabolic or postingestive processes.

. RESULTS: During the first year after onset of diabetes body weight (BW) increased 4.3 +/- 2.9 (0.1-8.3) kg (P = 0.0012) distributed as a 13.3% (1.6 kg) increase in total fat mass (FM) and 4.9% (2.5 kg) increase in lean body soft tissue mass (LBM). The self-reported weight loss at onset was 6.3 +/- 2.5 kg...... (1.5-10.0 kg). Compared with two reference populations the Metropolitan Life Insurance Co. and a healthy age and sex-matched local DXA scanned group the initial body composition data demonstrated BW 6.2 kg below ideal weight and a significant reduction of the FM (25% or -0.87 sd), whereas LBM...... was within the expected range. CONCLUSIONS: During the first year after onset of Type 1 diabetes the mean increase in BW is 6.5% with a 13.3% increase in FM and a 4.9% increase in LBM. Self-reported data on premorbid BW suggest an approximately 10% reduction in BW at onset of Type 1 diabetes. Compared...

Neuromedin U receptor 2 knockdown in the paraventricular nucleus modifies behavioral responses to obesogenic high-fat food and leads to increased body weight.

Neuromedin U (NMU) is a highly conserved neuropeptide which regulates food intake and body weight. Transgenic mice lacking NMU are hyperphagic and obese, making NMU a novel target for understanding and treating obesity. Neuromedin U receptor 2 (NMUR2) is a high-affinity receptor for NMU found in discrete regions of the central nervous system, in particular the paraventricular nucleus of the hypothalamus (PVN), where it may be responsible for mediating the anorectic effects of NMU. We hypothesized that selective knock down of NMUR2 in the PVN of rats would increase their sensitivity to the reinforcing properties of food resulting in increased intake and preference for high-fat obesogenic food. To this end, we used viral-mediated RNAi to selectively knock down NMUR2 gene expression in the PVN. In rats fed a standard chow, NMUR2 knockdown produced no significant effect on food intake or body weight. However, when the same rats were fed a high-fat diet (45% fat), they consumed significantly more food, gained more body weight, and had increased feed efficiency relative to controls. Furthermore, NMUR2 knockdown rats demonstrated significantly greater binge-type food consumption of the high-fat diet and showed a greater preference for higher-fat food. These results demonstrate that NMUR2 signaling in the PVN regulates consumption and preference for high-fat foods without disrupting feeding behavior associated with non-obesogenic standard chow.

Women's preferences for penis size may affect men's comfort with their own bodies and may have implications for sexual health. Studies of women's penis size preferences typically have relied on their abstract ratings or selecting amongst 2D, flaccid images. This study used haptic stimuli to allow assessment of women's size recall accuracy for the first time, as well as examine their preferences for erect penis sizes in different relationship contexts. Women (N = 75) selected amongst 33, 3D models. Women recalled model size accurately using this method, although they made more errors with respect to penis length than circumference. Women preferred a penis of slightly larger circumference and length for one-time (length = 6.4 inches/16.3 cm, circumference = 5.0 inches/12.7 cm) versus long-term (length = 6.3 inches/16.0 cm, circumference = 4.8 inches/12.2 cm) sexual partners. These first estimates of erect penis size preferences using 3D models suggest women accurately recall size and prefer penises only slightly larger than average.

Music is an important part of young people's lives. In this article, we attempt to answer two questions on the links between music et suicide. First, we examine if certain types of music favor suicidal process (ideation and acting out); and, secondly, we examine if music can constitute a tool to reduce the risk of suicide. Several factors possibly involved in links between musical preferences and the suicidal process are developed: the Velten effect and the musical mood induction procedure, the identification and the learning by imitation, the media influence as well as the individual characteristics. A multifactor approach is necessary to understand the complex and birectional links that unite musical preferences and suicide risk.

There is persisting interest in the idea that taste preferences are heritable characteristics, but few twin studies have found evidence for a significant genetic component. Small sample sizes and idiosyncratic selection of foods may have contributed to the negative results. We hypothesized that using a larger twin sample and empirical groupings of food types, would give stronger evidence for the heritability of food preferences. We examined the heritability of preferences for four food groups in a sample of young twins. We administered a food preference questionnaire with 95 foods to 214 mothers of same-sex twin pairs (103 monozygotic and 111 dizygotic pairs) aged 4 to 5. 18 foods were excluded because they had been tried by fewer than 25% of the children. Foods were grouped into 'Vegetables', 'Fruits', 'Desserts' and 'Meat and Fish' on the basis of a factor analysis of the preference data. Genetic analyses were carried out on mean liking across these four groups, using model fitting techniques. Over all 77 foods, MZ correlations were higher than DZ correlations for 72 of them, with a higher mean MZ correlation (r = 0.76) than DZ correlation (r = 0.56). Using model fitting techniques with the factor scores, significant heritability estimates were obtained for all four food groups. Heritability was modest for dessert foods (0.20), moderate for vegetables (0.37) and fruits (0.51), and high for liking for protein foods (0.78). Shared environmental effects were strong for desserts, fruits and vegetables, while non-shared environmental influences were low for all four food groups. These results provide strong evidence for modest heritability of food preferences when using empirically-derived groupings of foods.

Assessment of body temperature measurement options.

Science.gov (United States)

Sund-Levander, Märtha; Grodzinsky, Ewa

Assessment of body temperature is important for decisions in nursing care, medical diagnosis, treatment and the need of laboratory tests. The definition of normal body temperature as 37°C was established in the middle of the 19th century. Since then the technical design and the accuracy of thermometers has been much improved. Knowledge of physical influence on the individual body temperature, such as thermoregulation and hormones, are still not taken into consideration in body temperature assessment. It is time for a change; the unadjusted mode should be used, without adjusting to another site and the same site of measurement should be used as far as possible. Peripheral sites, such as the axillary and the forehead site, are not recommended as an assessment of core body temperature in adults. Frail elderly individuals might have a low normal body temperature and therefore be at risk of being assessed as non-febrile. As the ear site is close to the hypothalamus and quickly responds to changes in the set point temperature, it is a preferable and recommendable site for measurement of body temperature.

2011-10-01

The aim of this study was to estimate genetic parameters for fertility traits and linear type traits in the Czech Holstein dairy cattle population. Phenotypic data regarding 12 linear type traits, measured in first lactation, and 3 fertility traits, measured in each of first and second lactation, were collected from 2005 to 2009 in the progeny testing program of the Czech-Moravian Breeders Corporation. The number of animals for each linear type trait was 59,467, except for locomotion, where 53,436 animals were recorded. The 3-generation pedigree file included 164,125 animals. (Co)variance components were estimated using AI-REML in a series of bivariate analyses, which were implemented via the DMU package. Fertility traits included days from calving to first service (CF1), days open (DO1), and days from first to last service (FL1) in first lactation, and days from calving to first service (CF2), days open (DO2), and days from first to last service (FL2) in second lactation. The number of animals with fertility data varied between traits and ranged from 18,915 to 58,686. All heritability estimates for reproduction traits were low, ranging from 0.02 to 0.04. Heritability estimates for linear type traits ranged from 0.03 for locomotion to 0.39 for stature. Estimated genetic correlations between fertility traits and linear type traits were generally neutral or positive, whereas genetic correlations between body condition score and CF1, DO1, FL1, CF2 and DO2 were mostly negative, with the greatest correlation between BCS and CF2 (-0.51). Genetic correlations with locomotion were greatest for CF1 and CF2 (-0.34 for both). Results of this study show that cows that are genetically extreme for angularity, stature, and body depth tend to perform poorly for fertility traits. At the same time, cows that are genetically predisposed for low body condition score or high locomotion score are generally inferior in fertility. Copyright © 2011 American Dairy Science Association

Differential Gambling Motivations and Recreational Activity Preferences Among Casino Gamblers.

This study investigated three different types of gamblers (recreational, problem, and pathological gamblers) to determine differences in gambling motivations and recreational activity preferences among casino gamblers. We collected data from 600 gamblers recruited in an actual gambling environment inside a major casino in South Korea. Findings indicate that motivational factors of escape, sightseeing, and winning were significantly different among these three types of gamblers. When looking at motivations to visit the casino, pathological gamblers were more likely to be motivated by winning, whereas recreational gamblers were more likely to be motivated by scenery and culture in the surrounding casino area. Meanwhile, the problem gamblers fell between these two groups, indicating higher preferences for non-gambling activities than the pathological gamblers. As this study builds upon a foundational previous study by Lee et al. (Psychiatry Investig 6(3):141-149, 2009), the results of this new study were compared with those of the previous study to see if new developments within a resort-style casino contribute to changes in motivations and recreational activity preferences.

Assessing and honoring older adults' preferences is a fundamental step in providing person-centered care in long-term care facilities. Researchers and practitioners have begun to develop measures to assess nursing home (NH) residents' everyday preferences. However, little is known about how residents interpret and conceptualize their preferences and what specific clinical response may be needed to balance health and safety concerns with preferences. We used content analysis to examine interview responses on a subset of eight open-ended items from the Preferences of Every-day Living Inventory for Nursing Home (PELI-NH) residents with 337 NH residents (mean age 81). We considered how residents self-define various preferences of care and the associated importance of these preferences. Residents identified preferences for interpersonal interactions (greetings, staff showing care, and staff showing respect), coping strategies, personal care (bathroom needs, setting up bedding), and healthcare discussions. Respondents highlighted specific qualities and characteristics about care interactions that are necessary to fully meeting their everyday preferences. Results contribute to an emergent body of research that utilizes patient preferences to achieve the goals of person-centered care. The complexity of these responses substantiates the use of qualitative inquiry to thoroughly assess and integrate NH resident preferences into the delivery of person-centered care. © The Author 2015.

Camacho, Agustín; Rusch, Travis W

2017-08-01

Understanding methodological and biological sources of bias during the measurement of thermal parameters is essential for the advancement of thermal biology. For more than a century, studies on lizards have deepened our understanding of thermal ecophysiology, employing multiple methods to measure thermal preferences and tolerances. We reviewed 129 articles concerned with measuring preferred body temperature (PBT), voluntary thermal tolerance, and critical temperatures of lizards to offer: a) an overview of the methods used to measure and report these parameters, b) a summary of the methodological and biological factors affecting thermal preference and tolerance, c) recommendations to avoid identified pitfalls, and d) directions for continued progress in our application and understanding of these thermal parameters. We emphasize the need for more methodological and comparative studies. Lastly, we urge researchers to provide more detailed methodological descriptions and suggest ways to make their raw data more informative to increase the utility of thermal biology studies.

Hundreds of studies have investigated public perceptions and preferences about nuclear power, waste management, and technology. However there is clear lack of uniformity in the style, aims and methods applied.  Consequently, the body of results is inconsistent and it is difficult to isolate relevant patterns or interpretations. Nuclear Waste Management, Nuclear Power and Energy Choices: Public Preferences, Perceptions and Trust presents a theoretical base for public reactions then classifies and reviews the large body of surveys carried out over the past decade.   Particular focus is placed on residents within 50 miles US nuclear waste facilities due to the disproportionate presence of nuclear factors in their lives such as the legacy of nuclear waste disposal and job dependency. The motivations and reasons for their views such as fear, attraction to the economic benefits, trust of site managers and federal agencies, cultural views, personal history, and demographic attributes of the people are also conside...

Decreased left ventricular mass index in anorexia nervosa is amply reported. The aim of this study is to identify non-burdensome predictors of reduced left yentricular mass/height (cLVM) in a cohort of adolescent restrictive anorexic girls. This is a retrospective study of all anorexic girls of the restrictive type referred to our tertiary eating disorder unit between September 2002 and December 2012, for somatic assessment of weig ht loss. All subjects fulfilled DMS-IV criteria, without a family history of cardiac or cardiovascular diseases. In all, 283 restrictive anorexic girls (age: 14.63 +/- 1.65 y; body mass index: 15.72 +/- 1.81 kg/m2) were included. Ferritin and body mass index were independent, statistically significant predictors of the corrected left ventricular mass (P anorexia nervosa of the restrictive type. Two factors predicted decreased cLVM in our population: ferritin and BMI.

Although preference studies have been performed in diabetes, none have examined treatments used in diabetic retinopathy (DR. The objective of this study was to elicit patient preferences for attributes associated with antivascular endothelial growth factor, focal and panretinal laser, and steroid therapy used in DR management.Methods: A cross-sectional conjoint survey was administered to DR patients at three Canadian eye centers. The survey involved making tradeoffs among 11 DR treatment attributes, including the chance of improving vision and risks of adverse events over a 1-year treatment period. Attribute utilities were summed for each product profile to determine the most preferred treatment.Results: Based on the results from 161 patients, attributes affecting visual functioning, including improving visual acuity and reducing adverse events (eg, chance of cataracts, were more important than those not directly affecting vision (eg, administration. Overall, 52%, 20%, 17%, and 11% preferred the product profiles matching to the antivascular endothelial growth factor, steroid, focal laser, and panretinal laser therapies. Preferences did not vary substantially by previous treatment experience, age, or type of DR (macular edema, proliferative DR, both or neither, with the exception that more macular edema only patients preferred focal laser over steroid treatment (19% versus 14%, respectively.Conclusions: When considering the potential effects of treatment over a 1

Familiarity leads to preference (e.g., the mere exposure effect), yet it remains unknown whether it is objective familiarity, that is, repetitive exposure, or subjective familiarity that contributes to preference. In addition, it is unexplored whether and how different emotions influence familiarity-related preference. The authors investigated whether happy or sad faces are preferred or perceived as more familiar and whether this subjective familiarity judgment correlates with preference for different emotional faces. An emotional face--happy or sad--was paired with a neutral face, and participants rated the relative preference and familiarity of each of the paired faces. For preference judgment, happy faces were preferred and sad faces were less preferred, compared with neutral faces. For familiarity judgment, happy faces did not show any bias, but sad faces were perceived as less familiar than neutral faces. Item-by-item correlational analyses show preference for sad faces--but not happy faces--positively correlate with familiarity. These results suggest a direct link between positive emotion and preference, and argue at least partly against a common cause for familiarity and preference. Instead, facial expression of different emotional valence modulates the link between familiarity and preference.

Television consumption influences perceptions of attractive female body size. However, cross-cultural research examining media influence on body ideals is typically confounded by differences in the availability of reliable and diverse foodstuffs. 112 participants were recruited from 3 Nicaraguan villages that differed in television consumption and nutritional status, such that the contribution of both factors could be revealed. Participants completed a female figure preference task, reported their television consumption, and responded to several measures assessing nutritional status. Communities with higher television consumption and/or higher nutritional status preferred thinner female bodies than communities with lower television consumption and/or lower nutritional status. Bayesian mixed models estimated the plausible range of effects for television consumption, nutritional status, and other relevant variables on individual preferences. The model explained all meaningful differences between our low-nutrition villages, and television consumption, after sex, was the most likely of these predictors to contribute to variation in preferences (probability mass >95% when modelling only variables with zero-order associations with preferences, but only 90% when modelling all possible predictors). In contrast, we found no likely link with nutritional status. We thus found evidence that where media access and nutritional status are confounded, media is the more likely predictor of body ideals.

Full Text Available Abstract Background Alternative synonymous codons are not used with equal frequencies. In addition, the contexts of codons – neighboring nucleotides and neighboring codons – can have certain patterns. The codon context can influence both translational accuracy and elongation rates. However, it is not known how strong or conserved the codon context preferences in different organisms are. We analyzed 138 organisms (bacteria, archaea and eukaryotes to find conserved patterns of codon pairs. Results After removing the effects of single codon usage and dipeptide biases we discovered a set of neighboring codons for which avoidances or preferences were conserved in all three domains of life. Such biased codon pairs could be divided into subtypes on the basis of the nucleotide patterns that influence the bias. The most frequently avoided type of codon pair was nnUAnn. We discovered that 95.7% of avoided nnUAnn type patterns contain out-frame UAA or UAG triplets on the sense and/or antisense strand. On average, nnUAnn codon pairs are more frequently avoided in ORFeomes than in genomes. Thus we assume that translational selection plays a major role in the avoidance of these codon pairs. Among the preferred codon pairs, nnGCnn was the major type. Conclusion Translational selection shapes codon pair usage in protein coding sequences by rules that are common to all three domains of life. The most frequently avoided codon pairs contain the patterns nnUAnn, nnGGnn, nnGnnC, nnCGCn, GUCCnn, CUCCnn, nnCnnA or UUCGnn. The most frequently preferred codon pairs contain the patterns nnGCnn, nnCAnn or nnUnCn.

Human papillomaviruses (HPV) are the causative agents of cervical cancer in women, which results in over 250 000 deaths per year. Presently there are two prophylactic vaccines on the market, protecting against the two most common high-risk HPV types 16 and 18. These vaccines remain very expensive and are not generally affordable in developing countries where they are needed most. Additionally, there remains a need to treat women that are already infected with HPV, and who have high-grade lesions or cervical cancer. In this paper, we characterize the immunogenicity of a therapeutic vaccine that targets the E7 protein of the most prevalent high-risk HPV - type 16 – the gene which has previously been shown to be effective in DNA vaccine trials in mice. The synthetic shuffled HPV-16 E7 (16E7SH) has lost its transforming properties but retains all naturally-occurring CTL epitopes. This was genetically fused to Zera®, a self-assembly domain of the maize γ-zein able to induce the accumulation of recombinant proteins into protein bodies (PBs), within the endoplasmic reticulum in a number of expression systems. High-level expression of the HPV 16E7SH protein fused to Zera® in plants was achieved, and the protein bodies could be easily and cost-effectively purified. Immune responses comparable to the 16E7SH DNA vaccine were demonstrated in the murine model, with the protein vaccine successfully inducing a specific humoral as well as cell mediated immune response, and mediating tumour regression. The fusion of 16E7SH to the Zera® peptide was found to enhance the immune responses, presumably by means of a more efficient antigen presentation via the protein bodies. Interestingly, simply mixing the free PBs and 16E7SH also enhanced immune responses, indicating an adjuvant activity for the Zera® PBs

Sexual preferences can be strongly modified by Pavlovian learning. For instance, olfactory conditioned same-sex partner preference can occur when a sexually naïve male cohabits with an scented male during repeated periods under the effects of enhanced D2-type activity. Preference is observed days later via social and sexual behaviors. Herein we explored brain activity related to learned same-sex preference (Fos-Immunoreactivity, IR) following exposure to a conditioned odor paired with same-sex preference. During conditioning trials males received either saline or the D2-type receptor agonist quinpirole (QNP) and cohabitated during 24 h with a stimulus male that bore almond scent on the back as conditioned stimulus. This was repeated every 4 days, for a total of three trials. In a drug-free final test we assessed socio/sexual partner preference between the scented male and a receptive female. The results indicated that QNP-conditioned males developed a same-sex preference observed via contact, time spent, olfactory investigations, and non-contact erections. By contrast, saline-conditioned and intact (non-exposed to conditioning) males expressed an unconditioned preference for the female. Four days later the males were exposed to almond scent and their brains were processed for Fos-IR. Results indicated that the QNP-conditioned group expressed more Fos-IR in the nucleus accumbens (AcbSh), medial preoptic area (MPA), piriform cortex (Pir) and ventromedial nucleus of the hypothalamus (VMH) as compared to saline-conditioned. Intact males expressed the lowest Fos-IR in AcbSh and VMH, but the highest in MPA and Pir. We discuss the role of these areas in the learning process of same-sex partner preferences and olfactory discrimination. Copyright © 2018 Elsevier Inc. All rights reserved.

The Frozen Elephant Trunk (FET) can be adopted in selected type A acute aortic dissections (TAAAD). During FET, a prolonged distal circulatory arrest exposes the spine and visceral organs to potential ischemic injuries. Antegrade distal aortic perfusion (ADAP) could minimize this risk: we describe the technical aspects of the simultaneous use of antegrade cerebral perfusion (ACP) and ADAP achieving a "Whole Body Perfusion" (WBP) during FET.

Melipona eburnea Friese is a stingless bee kept in some regions of Colombia, where it is reported to be vulnerable to extinction due to habitat disturbance. To contribute to raising conservation strategies, the aim of this study was to identify the floral preferences of this species using melissopalynological analysis. A total of 31 pollen pot samples and 37 honey samples were taken from March 2009 through March 2010 from four colonies in Fusagasuga, Colombia. We found 92 pollen types: 17 from pollen pot samples, 39 from honey samples (indicating the sources of nectar), and 36 in both types of samples. The most frequent pollen types in the pollen pot samples were Myrcia type (100%), Eucalyptus globulus (96.9%), and Fraxinus uhdei (96.9%). The most frequent pollen types in honey samples were E. globulus (97.4%) and Myrcia type (94.9%). The pollen types corresponded mainly to native plants (68%), trees (44.5%), plants whose sexual system is hermaphroditic (56.5%), and plants with inflorescences (76.2%). The most frequent shapes of the flowers were brush-like (type Myrtaceae) and dish-like (type Asteraceae), and the preferred flower colors were white or cream (52.2%). In general, we found that M. eburnea showed a strong preference for trees of the family Myrtaceae to obtain nectar and pollen, including native and introduced species. Some other families are contributing significantly, such as Melastomataceae for pollen collection and Asteraceae for nectar. These results highlight the key plant species for the diet of M. eburnea.

Imaging Mental Representations of Sex-Typed Bodies: The Effect of Number of Trials on Image Quality

Full Text Available Sex categorization is a critical process in social perception. While psychologists have long theorized that perceivers have distinct mental representations of men and women that help them to achieve efficient sex categorizations, researchers have only recently begun using reverse-correlation to visualize the content of these mental representations. The present research addresses two issues concerning this relatively new methodological tool. First, previous studies of reverse-correlation have focused almost exclusively on perceivers’ mental representations of faces. Our study demonstrates that this technique can also be used to visualize mental representations of sex-typed bodies. Second, most studies of reverse-correlation have employed a relatively large number of trials (1,000+ to capture perceivers’ mental representations of a given category. Our study demonstrated that, at least for sex-typed representations of bodies, high quality reverse-correlation images can be obtained with as few as 100 trials. Overall, our findings enhance knowledge of reverse-correlation methodology in general and sex categorization in particular, providing new information for researchers interested in using this technique to understand the complex processes underlying social perception.

Comparison of Chain-Length Preferences and Glucan Specificities of Isoamylase-Type α-Glucan Debranching Enzymes from Rice, Cyanobacteria, and Bacteria.

Full Text Available It has been believed that isoamylase (ISA-type α-glucan debranching enzymes (DBEs play crucial roles not only in α-glucan degradation but also in the biosynthesis by affecting the structure of glucans, although molecular basis on distinct roles of the individual DBEs has not fully understood. In an attempt to relate the roles of DBEs to their chain-length specificities, we analyzed the chain-length distribution of DBE enzymatic reaction products by using purified DBEs from various sources including rice, cyanobacteria, and bacteria. When DBEs were incubated with phytoglycogen, their chain-length specificities were divided into three groups. First, rice endosperm ISA3 (OsISA3 and Eschericia coli GlgX (EcoGlgX almost exclusively debranched chains having degree of polymerization (DP of 3 and 4. Second, OsISA1, Pseudomonas amyloderamosa ISA (PsaISA, and rice pullulanase (OsPUL could debranch a wide range of chains of DP≧3. Third, both cyanobacteria ISAs, Cyanothece ATCC 51142 ISA (CytISA and Synechococcus elongatus PCC7942 ISA (ScoISA, showed the intermediate chain-length preference, because they removed chains of mainly DP3-4 and DP3-6, respectively, while they could also react to chains of DP5-10 and 7-13 to some extent, respectively. In contrast, all these ISAs were reactive to various chains when incubated with amylopectin. In addition to a great variation in chain-length preferences among various ISAs, their activities greatly differed depending on a variety of glucans. Most strikingly, cyannobacteria ISAs could attack branch points of pullulan to a lesser extent although no such activity was found in OsISA1, OsISA3, EcoGlgX, and PsaISA. Thus, the present study shows the high possibility that varied chain-length specificities of ISA-type DBEs among sources and isozymes are responsible for their distinct functions in glucan metabolism.

This study discusses about smartphone screen lock preferences using some types of authentication methods. The purpose is to determine the user behaviours based on the perceived security and convenience, as well as the preferences for different types of authentication methods. Variables used are the considerations for locking the screens and the types of authentication methods. The population consists of the smartphone users with the total samples of 400 respondents within a nonprobability sampling method. Data analysis method used is the descriptive analysis. The results showed that the convenience factor is still the major consideration for locking the smartphone screens. Majority of the users chose the pattern unlock as the most convenient method to use. Meanwhile, fingerprint unlock becomes the most secure method in the users’ perceptions and as the method chosen to be used in the future.
