Prejudice and attitudes of acculturation: perspectives of autochthonous and immigrants

This study is framed in a wider research on the acculturation process through a new acculturation model. The aim of this paper is to analyse the mutual prejudice between ethnic groups in contact and its relation to their preferred acculturation attitude. A questionnaire composed by various scales was given to four groups of people living in municipalities with high rate of African immigrants in Almería: Maghrebis, Sub-Saharans, Spaniards who evaluated the Maghreb out-group and Spaniards who responded on the Sub-Saharan out-group. The results obtained indicate a relation between prejudice and acculturation attitude, as the lowest scores in prejudice are hold in each group by people preferring integration , whilst the highest ones come from those who bow to exclusion/marginalisation.     

A Chilean version of the Efficient Personality Questionnaire for Adolescents

This investigation aims at adapting the test for Efficient Personality in educational contexts to Chilean reality. This instrument measures the construct efficient personality , made up of four levels of the self: strengths, requests, challenges and relationships. The original version has 58 items. In order to adapt it to our reality, 30 items were modified. The instrument was applied to a sample of 594 third and fourth secondary level students from four educational institutions of Vi?a del Mar. The new version of the instrument (23 items) presents a .85 reliability coefficient. The factorial analysis shows a structure of four basic factors which explain 50.42 % of the total variance. These factors, which are very similar those proposed in the original instrument, are named as academic self realization, social self realization, solving efficiency, and self steem. The second order factors analysis reveals a single factors structure that explains 43,28 % of the total variance, thus confirming the presence of the only factor that would correspond to the efficient personality construct presented.     

The entorhinal cortex plays a role in extinction

In this study, we analyzed the participation of the entorhinal cortex in extinction of a learned aversive response. Rats with infusion cannulae aimed to the entorhinal cortex were trained in a one-trial step-down inhibitory avoidance task (IA) and submitted to four consecutive daily test sessions without the footshock, a procedure that induced extinction of the conditioned response in control animals. When infused into the entorhinal cortex immediately after the first extinction session at doses able to block consolidation of IA memory, the NMDA receptor antagonist, AP5 (25 nmol/side), the inhibitor of protein synthesis anisomycin (300 nmol/side) and the inhibitor of CaMKII, KN-93 (10 nmol/side), but not the MEK1/2 inhibitor PD-98059 (5 nmol/side) hindered extinction of the IA response. The same results were obtained when the interval between the first and second test session was 48 instead of 24h. The data indicate that normal functionality of the NMDA receptors, together with CaMKII activity and protein synthesis are necessary in the entorhinal cortex at the time of the first test session to generate extinction. Our results also suggest that the ERK1/2 pathway does not play a role in this process.     

EthoSeq: A tool for phylogenetic analysis and data mining in behavioral sequences

This article introduces the software program called EthoSeq, which is designed to extract probabilistic behavioral sequences (tree-generated sequences, or TGSs) from observational data and to prepare a TGS-species matrix for phylogenetic analysis. The program uses Graph Theory algorithms to automatically detect behavioral patterns within the observational sessions. It includes filtering tools to adjust the search procedure to user-specified statistical needs. Preliminary analyses of data sets, such as grooming sequences in birds and foraging tactics in spiders, uncover a large number of TGSs which together yield single phylogenetic trees. An example of the use of the program is our analysis of felid grooming sequences, in which we have obtained 1,386 felid grooming TGSs for seven species, resulting in a single phylogeny. These results show that behavior is definitely useful in phylogenetic analysis. EthoSeq simplifies and automates such analyses, uncovers much of the hidden patterns of long behavioral sequences, and prepares this data for further analysis with standard phylogenetic programs. We hope it will encourage many empirical studies on the evolution of behavior.     

A stress management programme for Crohn's disease

The present study was designed to assess the effectiveness of techniques of behavioural assessment and treatment of Crohn's disease (CD). On the assumption that stress events have a pronounced influence on the life of Crohn's patients, we proposed stress management treatment. This is intended to control stress and improve patients' personal and social competence. Forty-five patients with Crohn's disease were randomly assigned to one of three treatment groups, two experimental groups: stress management and self-directed stress management, and a control group: conventional medical treatment. The subjects underwent eight individual sessions which were specific to each condition. All subjects completed symptom monitoring diaries. The subjects who received training in stress management experienced a significant post-treatment reduction of tiredness (P < 0.1), constipation (P < 0.1), abdominal pain (P < 0.5) and distended abdomen (P < 0.5). The subjects who received training in self-directed stress management experienced a significant reduction in tiredness (P < 0.1) and abdominal pain (P < 0.5). No significant changes were observed in symptomatology in the conventional medical treatment group. Similar results were obtained in the 12 month follow-up.     

Self-control, perceived opportunity, and attitudes as predictors of academic dishonesty

Academic dishonesty is a persistent and pervasive problem on college campuses. Researchers have suggested a variety of factors that influence academic dishonesty. The present study is an examination of the roles of self-control, attitude toward academic dishonesty, and perceived opportunity in predicting academic dishonesty. The dataset consisted of 853 survey responses from university students across the United States. The results showed that attitude toward academic dishonesty mediated the relationship between self-control and academic dishonesty and also between perceived opportunity and academic dishonesty. Implications of these findings are briefly discussed.     

Psychometric properties of the Spanish version of the self-perception profile for children

Harter's Self-perception Profile for Children was designed to assess children's domain-specific judgments of their competence (scholastic, social, athletic, physical, and behavioral), as well as global self-worth. The psychometric properties and exploratory factor analysis of the profile for two Spanish samples of children (49% boys and 51% girls; M age=11.1 yr., SD=9.7), were examined (n=23 from an after-school social care center in an economically deprived neighborhood and n=120 from a private school mainly enrolling families of medium socioeconomic status). All attending children between 9 and 12 yr. old were included. Analysis showed sex differences, with girls scoring lower than boys on Athletic Competence and higher on Behavioral Conduct. Children from the economically deprived group had higher scores on Social Acceptance and lower scores on Physical Appearance. The cross-cultural analysis showed that the Spanish control group scored significantly higher than the original American control group on Global Self-worth. A Spanish validation with 9- to 12-yr.-olds clearly replicated the five-factor structure reported by Harter in 1985 and also replicated the results obtained in other European samples, showing reliable and valid psychometric properties.     

Relationship between physical education students' achievements in a French badminton service test and expert ratings of technique quality

Assessment of practical skills in physical education lessons have often been criticised as subjective. In this study three experienced judges' ratings poorly predicted the 116 students' scores on the French badminton short service test.
