Emotional eating as a mediator between anxiety and cholesterol in population with overweight and hypertension

Although the relationship between cholesterol and mood states (especially anxiety) has been well studied, few researches have included the role of eating styles in this relationship. This study explored the associations among eating styles, negative emotional symptoms, and levels of cholesterol (and other medical variables) in a population with hypertension and overweight or obesity, analyzing the possible mediation mechanisms involved. A cross-sectional study was conducted in 68 adults with hypertension and overweight/obesity, and stepwise multiple regression analysis and mediation analyses were carried out to test the hypothesis that eating styles mediate the relationship between negative emotional symptoms and cholesterol. Several significant correlations among age, anthropometric, medical, and psychological variables (eating styles and negative emotional symptoms) were found. There was a significant indirect effect of anxiety on total cholesterol and LDL cholesterol through emotional eating. Results suggest that emotional eating has a relevant role in the rise in total and LDL cholesterol, acting as a mediator in the relationship between anxiety and cholesterol. This finding could have important implications, since it introduces a new variable in the relationship between emotions and cholesterol and, therefore, changes the way of understanding this relationship, and of treating high cholesterol in a hypertensive sample.     

Indiscernible universals

Universals have traditionally thought to obey the identity of indiscernibles, that is, it has traditionally been thought that there can be no perfectly similar universals. But at least in the conception of universals as immanent, there is nothing that rules out there being indiscernible universals. In this paper, I shall argue that there is useful work indiscernible universals can do, and so there might be reason to postulate indiscernible universals. In particular, I shall argue that postulating indiscernible universals can allow a theory of universals to identify particulars with bundles of universals, and that postulating indiscernible universals can allow a theory of universals to develop an account of the resemblance of quantitative universals that avoids the objections that Armstrong’s account faces. Finally, I shall respond to some objections and I shall undermine the criterion of distinction between particulars and universals that says that the distinction between particulars and universals lies in that while there can be indiscernible particulars, there cannot be indiscernible universals.     

Adjusting Venus: The Use of Maximum Elongations in the Almagest and Ptolemy’s Theory of Knowledge

There has been much debate surrounding the way in which Ptolemy handled the observations that are behind his planetary models. This article aims at presenting an interesting case of manipulation of observational data within the epistemological frame of what we may call Ptolemy’s philosophy of knowledge. It deals with an interesting case from the Almagest, that of the determination of the longitudes of the apogee and perigee of Venus’s deferent, and shows that the selections and adjustments Ptolemy carried out in order to obtain the needed results are nothing but an analogous application of the epistemological doctrines expressed in his On the Kriterion and in his Harmonics.     

Factor structure of the Spanish adaptation of Tarrant's Group Identification Scale

In this study, the factor structure of the Spanish version of Tarrant's Group Identification Scale is analyzed. This scale is based on the social identity theory and measures cognitive, evaluative, and affective aspects of group identification. Although this scale has been considered unidimensionally with adolescents, it is based on previous group identification scales considered multidimensionally. From confirmatory analysis, some factor models were tested in two independent samples of adolescents: Spanish (N= 1,795) and Mexican (N= 1,494). The three-factor model (self-categorization, group evaluation, and commitment to the group) produced the best fit in both samples. Results are compatible with the multidimensional structure hypothesis of group identification.     

Family Gender Role and Guilt in Spanish Dual-Earner Families

In dual-earner families the balance between work and family demands facilitates the development of guilt feelings when parents perceive a non-fulfillment of their responsibilities in childcare. Specifically, women who aspire to personal and professional development on the basis of more egalitarian gender role models must deal with the traditional stereotypes that maintain an intensive maternity mandate that prioritizes the family. On the other hand, for men the role change is primarily in the family setting with the development of a new father role more involved in the care of their children, which is not easily compatible with the more traditional breadwinner role. This study explored the feelings of guilt about parenting in 251 employed Spanish parents with children between 3 and 6 years of age, through the Scale of Guilt Feelings about Parenting, and its relationship with traditional stereotypes of maternal and family role. The scale addresses diverse situations pertaining to child rearing in which work requirements do not allow parents full availability for the care of their children. This availability is present in the model of intensive maternity and in the new father role model. Results indicate the presence of similar and high levels of guilt in fathers and mothers, although in men guilt is related to a non-traditional family role ideology, whereas in women guilt is related to a more traditional maternal role stereotype.     

Reputation, loneliness, satisfaction with life and aggressive behavior in adolescence

The present study analyses the relationship between adolescents' perception of reputation and aggressive behavior among peers. The sample is made up of 1319 adolescents aged 11 to 16-years-old. Statistical analyses with structural equation modeling were carried out to examine the direct and indirect effect of perception of reputation (real and ideal) on aggressive behavior. Results indicate that adolescents' real and ideal reputations are related both directly and indirectly to aggressive behavior. The indirect effects suggest that loneliness and life satisfaction mediate the relationship between adolescents' reputation and their aggressive behavior. These findings and their implications are discussed.     

Adjustment problems in the family and school contexts, attitude towards authority, and violent behavior at school in adolescence

This study analyzed the role of different but interrelated variables in the family and school contexts in relation to problems of violent behavior at school during adolescence. Participants were 1,068 students aged 11 to 16 (47% male) drawn from secondary schools in the Valencian Community (Spain). Statistical analyses were carried out using structural equation modeling. The model accounted for 32% of the variance in school violence. Results showed a direct association between quality of communication with father and teacher's expectations of the student with the adolescent's involvement in violent behavior at school. Moreover, findings showed indirect paths by which adolescents' self-concept (family and school domains), acceptance by peers, and attitude toward authority, seemed to be influenced by the quality of interactions with parent and teachers, and also were closely associated with violent behavior at school. Findings are discussed in relation to previous research on adolescent psychosocial adjustment and behavioral problems at school.     

The semantic organization of the animal category: evidence from semantic verbal fluency and network theory

Semantic memory is the subsystem of human memory that stores knowledge of concepts or meanings, as opposed to life-specific experiences. How humans organize semantic information remains poorly understood. In an effort to better understand this issue, we conducted a verbal fluency experiment on 200 participants with the aim of inferring and representing the conceptual storage structure of the natural category of animals as a network. This was done by formulating a statistical framework for co-occurring concepts that aims to infer significant concept-concept associations and represent them as a graph. The resulting network was analyzed and enriched by means of a missing links recovery criterion based on modularity. Both network models were compared to a thresholded co-occurrence approach. They were evaluated using a random subset of verbal fluency tests and comparing the network outcomes (linked pairs are clustering transitions and disconnected pairs are switching transitions) to the outcomes of two expert human raters. Results show that the network models proposed in this study overcome a thresholded co-occurrence approach, and their outcomes are in high agreement with human evaluations. Finally, the interplay between conceptual structure and retrieval mechanisms is discussed.
