Modeling Spatial Opportunity Structures and Youths’ Transitions from School to Training  [PDF]
Alexandra Wicht, Alexandra Nonnenmacher
Open Journal of Statistics (OJS) , 2017, DOI: 10.4236/ojs.2017.76071
Abstract: This paper examines the significance of spatial externalities for youths’ school-to-training transitions in Germany. For this purpose, it is necessary to address the methodological question of how an individual’s spatial context has to be operationalized with respect to both its extent and the problem of spatial autocorrelation. Our analyses show that the “zone of influence” comprises of the whole of Germany, not only close-by districts, and that these effects differ between structurally weak and strong regions. Consequently, assuming that only close proximity affects individual outcomes may disregard relevant contextual influences, and for spatial models that require an a priori definition of the weights for spatial units, it may be erroneous to make a decision based on this assumption. Concerning spatial autocorrelation, we found that neglecting local spatial autocorrelation at the context level causes considerable bias to the estimates, especially for districts that are close to the home district.

Abstract: a study was made of various bulk agents as sucrose substitutes in the formulation of chocolate, aiming to obtain a diet product in terms of sucrose and a light product in terms of calories (25% fewer calories than standard formulations containing sucrose) with good sensorial acceptance. the bulk agents used in this study were polydextrose, inulin, fructo-oligosaccharides - fos, lactitol and maltitol. sucralose was used as a high intensity sweetener. the light chocolates were analyzed for moisture content (karl fischer), particle size (digital micrometer), and rheological properties (casson plastic viscosity, hca, and yield strength, tca). the moisture content of the light chocolate varied from 1.23 to 2.12%, while particle size varied from 19 to 24 μm, hca from 6.60 to 11.00 pa.s, and tca from 0.05 to 1.10 pa. the formulations containing polydextrose, polydextrose and lactitol, and polydextrose and maltitol were selected for a sensory analysis due to their good technological performance and adequate machinability of the chocolate mass in the different stages of the process. the sensory analysis revealed no statistically significant difference (p > 0.05) in the three evaluated formulations in terms of aroma, hardness, melting in the mouth and flavor. there was no statistically significant difference (p > 0.05) in the intention to purchase the three chocolate formulations, although a preference was shown for the formulation containing polydextrose (32.60%) and maltitol (15.57%).

Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.52018

The purpose of the study was to examine intrinsic motivation of athletes and its relation with instructors’ verbal aggressiveness and leadership style. The sample of the study consisted of 168 athletes (95 boys and 73 girls), 15 - 19 years old (M = 16.5, SD = 0.5), participating in different individual and team sports (basketball, volleyball, football, long jump, pole vault, 200 m). Every participant completed three questionnaires, the Verbal Aggressiveness Questionnaire, the Intrinsic Motivation Inventory, and the Leadership Scale for Sports. The results revealed differences existing among variables of the instruments in terms of sex and type of sport (individual or team sport and contact or non contact sport). Pearson correlation revealed a significant positive relationship of coaches’ verbal aggressiveness with anxiety, autocratic style, and a negative significant relationship concerning coaches’ verbal aggression with enjoyment, ability, effort, and democratic style. Findings and implications for instructors’ type of communication were discussed and future research suggestions were included.

Verbally Aggressive Instructors and Machiavellian Students: Is the Socio-Communicative Style an Over-Bridging?  [PDF]

Psychology (PSYCH) , 2017, DOI: 10.4236/psych.2017.810095
Abstract: Goals of this research are: 1) to examine the role of gender, 2) to explore the relationship between perceived instructors’ verbal aggressiveness, socio-communicative style and students’ Machiavellian tactics, 3) to investigate the influence of instructors’ verbal aggressiveness on their socio-communicative style and students’ Machiavellian tactics in physical education context and 4) to propose a students’ and instructors’ typology which will be the final over-bridging of verbal aggressiveness and Machiavellianism through communication style. The sample consisted of 269 students (141 males, 128 females) aged 12 - 14 years old (M = 12.6, SD = 0.65) from secondary public schools who completed three types of questionnaires during physical education classes. The results supported the internal consistency of the instruments. According to the results of the study, statistically significant differences were observed in perceived instructors’ verbal aggressiveness, responsiveness, assertiveness and students’ amoral manipulation, desire for control, desire for status, distrust of others between the genders of the students. Correlational analysis indicated that perceived instructors’ verbal aggressiveness was positively related to assertiveness, amoral manipulation, desire for control, desire for status, distrust of others and was negatively related to responsiveness. The results of regression analysis revealed that perceived instructors’ verbal aggressiveness could significantly predict the variables of responsiveness, assertiveness, desire for status and distrust of others. Three behavioral types are revealed: 1) the unrestraint, 2) the responsive, and 3) the distrustful, where verbal aggressiveness appears to be connected with Machiavellianism through communication style in these particular combinations.

Abstract: This study aimed to examine the predictors of better self-care behavior in patients with heart failure (HF) in a home visiting program. This is a longitudinal study nested in a randomized controlled trial (ISRCTN01213862) in which the home-based educational intervention consisted of a six-month followup that included four home visits by a nurse, interspersed with four telephone calls. The self-care score was measured at baseline and at six months using the Brazilian version of the European Heart Failure Self-Care Behaviour Scale. The associations included eight variables: age, sex, schooling, having received the intervention, social support, income, comorbidities, and symptom severity. A simple linear regression model was developed using significant variables ( ), followed by a multivariate model to determine the predictors of better self-care. One hundred eighty-eight patients completed the study. A better self-care behavior was associated with patients who received intervention ( ), had more years of schooling ( ), and had more comorbidities ( ). Having received the intervention ( ) and having a greater number of comorbidities ( ) were predictors of better self-care. In the multivariate regression model, being in the intervention group and having more comorbidities were a predictor of better self-care. 1. Introduction Self-care in heart failure (HF) is defined as positive behaviors leading to decisions and actions that an individual can take to help maintain clinical stability and cope with the disease [1]. Studies indicate that the inability of patients to recognize signs and symptoms of congestive episodes and the lack of knowledge and poor adherence to treatment, components that are considered self-care measures, are precipitating factors leading to decompensation of HF [2–5]. Within this context, all self-care behaviors appear to be directly related to motivation, habits, and sociodemographic and clinical characteristics, factors that may affect the way individuals live their lives [1, 6–8]. In this sense, the home environment has gained attention as a potential setting for the development of education strategies and followup of patients with HF, as well as for the investigation of the benefits of such strategies and their effect on self-care behaviors [9–11]. Jaarsma et al. [9], in one of the first published studies on the topic, tested in a randomized controlled trial (RCT) the effect of an education strategy on self-care initiated during hospitalization, followed by a telephone call and a home visit within 10 days after hospital discharge.

Paradigmas de interpreta??o das rela??es raciais no Brasil
Motta, Roberto;
Estudos Afro-Asiáticos , 2000, DOI: 10.1590/S0101-546X2000000200006
Abstract: three paradigms can be distinguished in the study of racial relations in brazil during the nineteenth century. the first of them, the dark-complexion [morenidade] paradigm, is associated to gilberto freyre. despite seeming disagreements, however, it is shared by marvin harris and carl degler, whose formulations about "a referential ambiguity in the assessment of racial identity" and "neither black nor white" have essentially the same meaning as "dark-complexioned". a second paradigm relates to florestan fernandes, who stresses the purely residual nature of racial prejudice and inequality in brazil. the third one, chiefly associated to carlos hasenbalg, states that persistent racial discrimination is the cause of inequality between whites and non-whites in the realms of economy, education, and other social indicators. the differences between those paradigms as well as among authors who adhere to substantially identical ones result largely from different models of history and development.
Estilos mortuários e modos de sociabilidade em cemitérios Brasileiros oitocentistas
Motta, Antonio;
Horizontes Antropológicos , 2010, DOI: 10.1590/S0104-71832010000100005
Abstract: that which guides the analytic focus of this article is the social treatment given to the dead and forms of burial at the end of the 19th and the first decades of the 20th centuries. how can we read and understand social meanings and attitudes of a determined time from the system of funerary objects and mortuary practices and styles? when subjected to readings, the funerary devices and styles molded on the tombs allow for the translation not only of accommodations and equilibriums, but also tensions and significant changes in affective relations that the living establish with their dead.
La historia, la comida, la salud: Un vínculo siempre más estrecho entre alimentación y medicina
Medicina y Seguridad del Trabajo , 2010, DOI: 10.4321/S0465-546X2010000100008
Abstract: in the ancien regime societies, during the age of enlightment, the influence of scientific and rational thinking paved the way top a new medical culture. in this new medical approach, food habits dramatically changed. alimentation assumed a social role and a deeper attention was devoted to health. doctors started to focus on diet, hygienic conditions, environmental quality. since middle age specific works (tractati) were devoted to food properties by indicating benefits of some foods and warning against others. doctors prescribed fasting as a therapy. henceforth a deeper relation between health and food was established. the recipe books (ricettari) of hospitals reported the appropriate purpose of foods, vegetables and herbs, fruits and salads whose pictures appeared in naturalist as well as in cooking books. the excessive and luxurious banquets of the aristocracy were subsequently replaced by the cheaper meals of the bourgeoisie, although the burghers used food as a way to mark social differences. as the scientific knowledge advanced food habits became healthier through centuries. a basic concept to avoid alimentary excesses prevailed in contemporary age.
