Accuracy in discriminating blood glucose levels in a sample of children with type 1 diabetes

The present study explores accuracy in estimating blood glucose levels (BGL) in children with type 1 diabetes and analyzes the kinds of symptoms and cues which they use to estimate their BGL. Forty two children with type 1 diabetes completed a SI/IC-3 scale consisting of 28 items (22 symptoms and 6 feelings), indicating those which they perceived at the time and their intensity. They estimated their BGL and gave reasons for their estimation, before having a blood glucose level analysis performed. The results indicated great variability in the accuracy of estimating BGL. They showed failures in the correct discrimination of symptoms of hypoglycemia as well as the presence of false beliefs regarding indicative symptoms of hyperglycemia, and the absence of symptoms as an indicator for euglycemia, beliefs which provoke different and frequent errors in the estimation of BGL. Correct use of external signs is shown to be related to correct estimations of normal BGL, as well as hypoglycemia and hyperglycemia. We discuss the implications these results could have on designing psychological intervention procedures for diabetics in the form of training programs to discriminate BGL accurately, taking into account these findings and previous studies completed in the same field.     

A meta-analytic study of general mental ability validity for different occupations in the European community

A comprehensive meta-analysis of the validity of general mental ability (GMA) measures across 12 occupational categories in the European Community (EC) is presented. GMA measures showed that there is validity generalization and large operational validities for job performance and training success in 11 occupational groups. Results also showed that job complexity moderated the magnitude of the operational validity of GMA tests across three levels of job complexity: low, medium, and high. In general, results were similar to those found in the United States, although the European findings showed a slightly larger magnitude of operational validity in some cases. Theoretical and practical implications of these findings for personnel selection are discussed. ((c) 2003 APA, all rights reserved)     

Young adults' partner preferences and parents' in-law preferences across generations,genders, and nations

To examine cultural, gender, and parent–child differences in partner preferences, in eight countries undergraduates (n = 2,071) and their parents (n = 1,851) ranked the desirability of qualities in someone the student might marry. Despite sizable cultural differences—especially between Southeast Asian and Western countries—participants generally ranked kind/understanding (reflecting interpersonal communion) highest, and intelligent and healthy (reflecting mental/physical agency) among the top four. Students valued exciting, attractive partners more and healthy, religious partners less than parents did; comparisons with rankings by youth in 1984 (i.e., from the parents' generation) suggested cohort effects cannot explain most parent–child disagreements. As evolutionary psychology predicts, participants prioritized wives' attractiveness and homemaker skills and husbands' education and breadwinner skills; but as sociocultural theory predicts, variations across countries/decades in gendered spousal/in-law preferences mirrored socioeconomic gender differences. Collectively, the results suggest individuals consider their social roles/circumstances when envisioning their ideal spouse/in-law, which has implications for how humans’ partner-appraisal capabilities evolved.     

Behavioral problems in adolescents raised by their grandparents

This research analyzes, for the first time using a Spanish sample, the behavioral problems of adolescents in the custody of their grandparents. The sample consisted of 68 adolescents (31 boys and 37 girls, with a mean age of 13.7 years) in the custody of 54 grandparents with an average age of 65.9 years for the grandfathers, and 63.6 years for the grandmothers. The instrument employed was the Child Behavior Checklist (CBCL; Achenbach, 2001). The results indicate that the majority of both boys and girls can be classified within the normal range on scales of internal behavior, external behavior and total behavioral problems. When gender and age differences were analyzed, it was found that boys had more behavioral problems than girls on scales of incompliance with rules and external behavior. Meanwhile, it was shown that older adolescents had more somatic problems, as well as more behavioral problems, as measured by both the internal scale and total scale of the CBCL, than the younger participants.     

Body sensations associated with emotions in Rarámuri Indians, rural Javanese, and three student samples

Cultural variations in the associations of 12 body sensations with 7 emotions were studied in 2 rural samples from northern Mexico (n = 61) and Java, Indonesia (n = 99), with low exposure to Western influences and in 3 university student samples from Belgium (n = 75), Indonesia (n = 85), and Mexico (n = 123). Both parametric and nonparametric analyses suggest that findings from previous studies with only student samples (K. R. Scherer & H. G. Wallbott, 1994) were generalizable to the 2 rural samples. Some notable cultural deviations from common profiles were also identified. Implications of the findings for explanations of body sensations experienced with emotions and the cross-cultural study of emotions are discussed.     

Influence of the recording interval and a graphic organizer on the writing process/product and on other psychological variables

An experimental study of the influence of the recording interval and a graphic organizer on the processes of writing composition and on the final product is presented. We studied 326 participants, age 10 to 16 years old, by means of a nested design. Two groups were compared: one group was aided in the writing process with a graphic organizer and the other was not. Each group was subdivided into two further groups: one with a mean recording interval of 45 seconds and the other with approximately 90 seconds recording interval in a writing log. The results showed that the group aided by a graphic organizer obtained better results both in processes and writing product, and that the groups assessed with an average interval of 45 seconds obtained worse results. Implications for educational practice are discussed, and limitations and future perspectives are commented on.     

Relationship between burnout, job strain, and sleep characteristics

The purpose of the present study is to analyse the relationship between sleep, burnout, and job strain in a sample of 316 healthy workers from various professional sectors. Multiple significant correlations between the principal sleep parameters, the dimensions of burnout, and job strain were found. The regression analyses show that sleep quality and various dimensions of job strain are significant predictors of several aspects of burnout. Sleep quality explains an even higher percentage of the variance in emotional exhaustion than the variance explained by more well-known variables such as job demands. Moreover, sleep quality interacts with aspects of job strain in its influence on the dimensions of burnout, although the exact relationship between these variables needs to be investigated in future longitudinal studies. Our results suggest that interventions to optimise sleep habits could prevent or alleviate burnout and could be a part of organisational work.     

Seven psychosocial principles to explain terrorism

Research approaches leading to the understanding of the terrorist phenomenon are suggested. Seven principles explaining terrorism are analysed from a psychosocial approach: They could complete the explanations of terrorism focused in socio-structural and psychological variables, the latter being insufficient and often erroneous. Thus, terrorism is presented as a strategy of political influence, and the psychological attributes of terrorists are explained as the result of several influential social processes. We considered that terrorist attacks and campaigns correspond to strategic reasons, but we also assume that the rationality of the terrorists perspective is limited. As far as the organisational parameters are concerned, we propose an analogy with ordinary social movements, especially relating to their ideological frameworks of legitimisation and resource mobilization processes.     

Why are good theories good? reflections on epistemic values, confirmation, and formal epistemology

Franz Huber’s (2008a) attempt to unify inductivist and hypothetico-deductivist intuitions on confirmation by means of a single measure are examined and compared with previous work on the theory of verisimilitude or truthlikeness. The idea of connecting ‘the logic of confirmation’ with ‘the logic of acceptability’ is also critically discussed, and it is argued that ‘acceptability’ takes necessarily into account some pragmatic criteria, and that at least two normative senses of ‘acceptability’ must be distinguished: ‘acceptable’ in the sense of ‘being allowed to accept’, and ‘acceptable’ in the sense of ‘being obliged to accept’. Lastly, some connections of confirmation theory with naturalism, intertheoretic reduction, and explanation vs. understanding are explored.
