Familism, family environment, and suicide attempts among Latina youth

In this study, we examined the relationship between familism and family environment type as well as the relationship between family environment type and suicide attempts among Latina youth. Latina teen attempters (n = 109) and nonattempters (n = 107) were recruited from the New York City area. Latent class analysis revealed three family environment types: tight-knit, intermediate-knit, and loose-knit. Tight-knit families (high cohesion and low conflict) were significantly less likely to have teens who attempted suicide as compared with intermediate-knit families or loose-knit families. Moreover, familism increased the odds of being in a tight-knit family versus a loose-knit family and the odds of being in a tight-knit family versus a intermediate-knit. The results suggest that familism may protect against suicide behavior among Latinas via its influence on family environment.     

Tolerance towards dating violence in Spanish adolescents

The study of intimate partner violence among adolescent and young couples in Spain remains unattended, although such abuses are well known and more frequent than in adulthood. The aim of this study is, on the one hand, to provide epidemiological information on dating relationships, and on the other hand, to identify attitudes towards violence. 2205 women enrolled in schools in diverse provinces of Spain, participated in the study. Average age was near 19 years (SD= 2.25). The Dating Violence Questionnaire (DVQ, in Spanish, CUVINO), a questionnaire that assesses both frequency and distress associated with violent behavior, was used. The DVQ allowed differentiating between groups of women self-labeled as abused and not abused on the basis of the frequency of sustained violence, although the levels of distress in the face of violence were statistically similar in both groups. Implications for future research and prevention programs are discussed.     

Spanish adaptation of the Perceived Acceptance Scale (PAS) in university students

The main objective of the present study was to adapt the Perceived Acceptance Scale (PAS), developed by Brock, Sarason, Sanghvi and Gurung to evaluate the cognitive component of perceived social support, to the Spanish language. In a sample of 855 university students registered for the first time in different degree courses, the reliability, dimensionality and external validity of the scale scores were analyzed. The results show adequate internal consistency in both the subscales (friends, family, father and mother) and in the overall scale. The factorial structure, derived from a confirmatory factorial analysis, fitted the theoretical model proposed by the authors of the scale. The scale scores showed evidence of convergent and discriminant validity from the observed relationships with the measures of perceived social support. The psychometric properties of the adapted scale provide an adequate measuring instrument for evaluating perceived acceptance in Spanish university students.     

Sleep enhances memory consolidation in the hippocampus-dependent object-place recognition task in rats

The positive impact of sleep on memory consolidation has been shown for human subjects in numerous studies, but there is still sparse knowledge on this topic in rats, one of the most prominent model species in neuroscience research. Here, we examined the role of sleep in the object-place recognition task, a task closely comparable to tasks typically applied for testing human declarative memory: It is a one-trial task, hippocampus-dependent, not stressful and can be repeated within the same animal. A test session consisted of the Sample trial, followed by a 2-h retention interval and a Test trial, the latter examining the memory the rat had for the places of two objects presented at the Sample trial. In Experiment 1, each rat was tested twice, with the retention interval taking place either in the morning or evening, i.e., in the inactive or active phase, respectively. Rats showed significantly (p<0.01) better memory for object place after the Morning session. To control for confounding circadian factors, in Experiment 2 rats were tested four times, i.e., in the morning or in the evening while sleep was or was not deprived. Sleep during the retention interval was recorded polysomnographically. Rats only showed significant memory for the target object place in the Test trial after the Morning retention interval in the absence of sleep deprivation, and recognition performance in this condition was significantly superior to that in the three other conditions (p<0.05). EEG recordings during spontaneous morning sleep revealed increased slow oscillation (0.85-2.0 Hz) and upper delta (2.0-4.0 Hz), but reduced spindle band (10.5-13.5 Hz) activity, as compared to evening sleep. However, spindle band power was increased in the Morning retention interval in comparison to a Morning Baseline period (p<0.05). We conclude that consolidation of object-place memory depends on sleep, and presumably requires NonREM sleep rich in both slow wave and spindle activity.     

Female physical attractiveness in Britain and Japan: a cross‐cultural study

Two purported cues to female physical attractiveness are body mass index (BMI) and body shape as measured by the waist‐to‐hip ratio (WHR). This study examined the relative contribution of both cues in two culturally distinct populations. Eighty‐two male participants from Britain and Japan were asked to rate a set of images of real women with known BMI and WHR. Results showed that BMI is the primary determinant of female physical attractiveness, whereas WHR failed to emerge as a significant predictor. Results also showed that there were significant differences in preferences for physical attractiveness, with Japanese participants preferring images of women with significantly lower BMIs than Britons. Finally, results showed that the Japanese are more reliant on body shape than Britons when judging physical attractiveness. The findings are discussed in terms of evolutionary psychological explanations of mate selection, and sociocultural theories which emphasise the learning of preferences in social and cultural contexts.

Zahnhartsubstanzschäden bei Essstörungen

Eating disorders such as anorexia nervosa and bulimia nervosa lead to several serious physical problems. One possible consequence is acid-related dental erosion. Dental erosion can be identified early and is caused by exogenic (selection of food) and / or endogenic (gastric acid) factors. That is why dentists play an important role in the early identification of eating disorders as well as in the prevention and therapy of dental erosion. They should be important collaborators of psychotherapists. We review characteristic damages to the teeth that are seen in eating disorders as well as preventive and therapeutic interventions. Psychotherapists should be informed about dental problems and preventive strategies to educate their patients.     

Tests of encoding tradeoffs between item and associative information

The assumption that item and associative information are processed separately and that there is a tradeoff in the amount of each type of information that can be encoded in a given study interval (e.g., Anderson & Bower, 1972; Murdock, 1982, 1992) was examined. When item information was emphasized at study, recognition memory for associative information was poor, demonstrating that item information can be emphasized over associative information. In contrast, when associative information was emphasized, associative recognition greatly improved but item recognition did not suffer. This pattern of results was found at both fast and slow presentation rates, and for both high and low word concreteness and word frequency. Measures of confidence and response latency were also consistent with this pattern. Thus, the encoding of associative information did not measurably diminish item recognition performance.     

Tangibles as predictors of customer satisfaction in sports services

This study investigates the power of tangible dimensions of service quality to predict customer satisfaction. For this purpose, we statistically controlled the effects of dimensions of service quality that describe social interaction between employees and customers, both functionally and relationally. A field survey was conducted with the participation of 556 customers of a sports centre. The results showed that tangible dimensions of service quality predicted an additional and significant amount of customer satisfaction variance, beyond the effects of service quality of the social interaction. The article concludes with the discussion of the implications of these results.     

Making sense of word senses: the comprehension of polysemy depends on sense overlap

Studies of polysemy are few in number and are contradictory. Some have found differences between polysemy and homonymy (L. Frazier & K. Rayner, 1990), and others have found similarities (D. K. Klein & G. Murphy, 2001). The authors investigated this issue using the methods of D. K. Klein and G. Murphy (2001), in whose study participants judged whether ambiguous words embedded in word pairs (e.g., tasty chicken) made sense as a function of a cooperating, conflicting, or neutral context. The ambiguous words were independently rated as having low, moderate, or highly overlapping senses to approximate a continuum from homonymy to metonymic polysemy. The effects of meaning dominance were examined. Words with highly overlapping meanings (e.g., metonymy) showed reduced effects of context and dominance compared with words with moderately or low overlapping meanings (e.g., metaphorical polysemy and homonymy). These results suggest that the comprehension of ambiguous words is mediated by the semantic overlap of alternative senses/meanings.
