Relational‐Cultural Theory–Based Interventions With LGBTQ College Students

Lesbian, gay, bisexual, transgender, and queer (LGBTQ) community members can encounter daily challenges living in a heterosexist society, including the college milieu. The authors apply the tenets of relational‐cultural theory (RCT) to LGBTQ college students. Furthermore, a case study is included to highlight ways counselors can infuse RCT strategies when working with this population.     

Internalized Racism,Perceived Racism,and Ethnic Identity: Exploring Their Relationship in Latina/o Undergraduates

For Latina/o undergraduates, ethnic identity is an important construct linked to self‐esteem and educational attainment. Internalized and perceived racism have been hypothesized to hinder ethnic identity development in Latina/o undergraduates. To assess if internalized and perceived racism were inversely related to ethnic identity, the author conducted a hierarchical linear regression with 373 Latina/o undergraduates. There was a significant relationship between internalized racism and ethnic identity. Findings indicate a need to challenge internalized racism in Latina/o undergraduates.     

Global Citizenship and Global Universities. The Age of Global Interdependence and Cosmopolitanism

This article focuses on the role of global universities and globalisations in an age of global interdependence and cosmopolitanism. Competing agendas that result from actions and reactions to multiple globalisations are considered in relation to global citizenship education. These agendas are crucial in understanding dilemmas of the local and the global in relation to education. Key emerging agendas are highlighted, including those of the hyperglobalisers, skeptics and transformationists. Three themes are central for this conversation, namely a) how multiple globalisations are impacting global life and academics, b) how networks have become privileged sites for global education, and c) the implications of globalisation and networks for global citizenship and global universities.     

Education and development in Latin America (1950–1975)

Structural analysis of educational development in Latin America shows the determining effect of economic and social trends. The past 25 years have seen a shift to industrialization and increasing involvement of foreign capital, visible in growing urbanization as well as in modernized agriculture focused on export. The reduction of job opportunities in both traditional and modern sectors has not been offset by the emerging service sector, although social structures have been deeply affected by these trends.The authors place in this context their analysis of education at successive levels. Progress in primary school enrolment has been real in the region, but with market disparities between countries and with little evidence of increased efficiency (i.e. enduring literacy) or equity. The basic fact is that this level of education has lost its economic value and prepares only for activities of low productivity.At secondary level, expansion has been considerable, even in countries with an inadequate primary infrastructure. A growing dichotomy is evident as schools continue to perpetuate classical values and forms while failing to establish links with the labour market. The effect is seen in growing pressure on higher education, where rapid expansion has led to fragmentation of institutions and a depreciation of standards.The relationship of education to development in these past 25 years has brought about a wide perception of the conservative role played by education, as the mechanism for reproducting the dominant cultural models and ideologies. This critical distrust, shared by teachers and students alike, may indeed be a force strong enough to create a new model of development.

Zusammenfassung Eine strukturelle Analyse der Entwicklung des Bildungswesens in Latein-Amerika zeigt die entscheidende Auswirkung wirtschaftlicher und sozialer Tendenzen. Die Letzten 25 Jahre sahen eine Veränderung in Richtung auf Industrialisierung und zunehmende ausländische Kapitalbeteiligung, was ebenso in wachsender Verstädterung wie in Modernisierung der Landwirtschaft mit Konzentration auf den Export in Erscheinung tritt. Durch den aufkommenden Dienstleistungsbereich wurde der Rückgang der Stellenangebote sowohl in traditionellen als auch in modernen Bereichen nicht ausgeglichen, wenn auch die gesellschaftlichen Strukturen durch diese Tendenzen stark in Mitleidenschaft gezogen wurden.In diesen Zusammenhang stellen die Autoren ihre Analyse der Bildung auf den aufeinanderfolgenden Stufen hinein. Bei der Aufnahme in die Primarschule hat in Latein-Amerika tatsächlich ein Fortschritt stattgefunden, allerdings mit deutlichen Unterschieden zwischen den einzelnen Ländern und wenig erkennbarer Leistungssteigerung (d.h. andauernder Überwindung des Analphabetentums) oder Ausgleich. Es ist eine grundlegende Tatsache, daß diese Bildungsstufe ihren wirtschaftlichen Wert verloren hat und nur auf Aktivitäten mit geringer Produktivität vorbereitet.Auf der Sekundarstufe vollzog sich eine beachtliche Erweiterung, sogar in Ländern mit ungeeigneter primärer Infrastruktur. Deutlich zeigt sich eine zunehmende Dichotomie, da die Schulen fortfahren, klassische Werte und Formen weiterzugeben, und dabei versäumen, Brücken zum Arbeitsmarkt zu schlagen. Dies wirkt sich in zunehmendem Druck auf die höhere Bildung aus, wo schnelle Ausweitung zur Zersplitterung von Institutionen und zur Senkung der Anforderungen geführt hat.Durch die Beziehung zwischen Bildung und Entwicklung in den letzten 25 Jahren wurde die konservative Rolle des Bildungswesens deutlich wahrnehmbar, ist es doch ein Mechanismus zur Reproduktion der herrschenden kulturellen Modelle und Ideologien. Tatsächlich kann vielleicht dieses von Lehrern wie Schülern gleichermaßen gehegte kritische Mißtrauen eine genügend starke Kraft sein, um ein neues Entwicklungsmodell zu schaffen.

Résumé L'analyse structurale du développement de l'éducation en Amérique Latine montre l'effet déterminant des courants sociaux et économiques. Ces dernières vingt-cinq années ont vu un glissement vers l'industrialisation et une intervention croissante des capitaux étrangers. Ceci est visible dans l'urbanisation grandissante et dans la modernisation de l'agriculture axée sur l'exportation. La réduction des chances de travail dans le secteur traditionnel aussi bien que dans le secteur moderne, n'a pas été compensée par une ouverture dans celui des services en formation, bien que les structures sociales aient été profondément affectées par ces courants.C'est dans ce contexte que les auteurs placent leur analyse de l'éducation à des niveaux successifs. En ce qui regarde la fréquentation de l'école primaire, le progrès a été indéniable dans toute l'Amérique Latine, avec toutefois des inégalités marquées selon les pays, et sans grand évidence d'efficacité croissante (c'est-à-dire alphabétisation persistante) ou d'équité. Un fait certain est que ce niveau d'éducation a perdu sa valeur économique et ne prépare qu'à des activités de basse productivité.Au niveau secondaire, l'expansion a été considérable, même dans les pays dont l'infrastructure primaire est inadéquate. Il est certain que la dichotomie va aller en s'amplifiant puisque les écoles continuent de perpétuer les valeurs et les formes classiques sans parvenir à établir des rapports avec le marché du travail. On en constate l'effet dans la pression grandissante qui s'exerce sur l'éducation supérieure, où l'expansion rapide a conduit à la fragmentation d'institutions et à une dépréciation des normes.Les relations entre l'éducation et le développement, au cours de ces vingt-cinq dernières années, ont conduit à une prise de conscience largement répandue du rôle conservateur de l'éducation, en tant que mécanisme de reproduction des idéologies et des modèles culturels dominants. Cette méfiance critique, partagée par les enseignants et les étudiants, peut devenir une force suffisamment puissante pour créer un nouveau modèle de developpement.

     

Acute effects of aerobic exercise performed with different volumes on strength performance and neuromuscular parameters

The aim of the present study was to investigate the acute effect of the aerobic exercise volume on maximum strength and strength-endurance performance; and possible causes of strength decrements (i.e. central and peripheral fatigue). Twenty-one moderately trained men were submitted to a maximal incremental test to determine anaerobic threshold (AnT) and maximum dynamic strength (1RM) and strength-endurance (i.e. total volume load [TV]) tests to determine their baseline strength performance. Following, subjects performed six experimental sessions: aerobic exercise sessions (continuous running at 90% AnT) with different volumes (3?km, 5?km or 7?km) followed by 1RM or strength-endurance test in the 45° leg press exercise. Maximum voluntary isometric contraction (MVIC), voluntary activation (VA) level, contractile properties, and electromyographic activity (root mean square [RMS]) of the knee extensor muscles were assessed before and after aerobic exercises and after strength tests. TV was lower after 5?km and 7?km runs than in the control condition (12% and 22%, respectively). Additionally, TV was lower after 7?km than 3?km (14%) and 5?km (12%) runs. MVIC, VA, RMS, and contractile properties were reduced after all aerobic exercise volumes (～8%, ～5%, ～11% and ～6–14%, respectively). Additionally, MVIC, VA, and contractile properties were lower after strength tests (～15%, ～6%, ～9–26%, respectively). In conclusion, strength-endurance performance is impaired when performed after aerobic exercise and the magnitude of this interference is dependent on the aerobic exercise volume; and peripheral and central fatigue indices could not explain the different TV observed.     

Sprinting analysis of elite soccer players during European Champions League and UEFA Cup matches

It has been suggested that assessment of high-intensity activities during a match is a valid measure of physical performance in elite soccer. Recently, sprinting activities have been analysed in more depth. The aim of this study was to develop a detailed analysis of the sprinting activities of different playing positions during European Champions League and UEFA Cup competitions. Altogether, 717 elite outfield soccer players were evaluated throughout 2002-2006 using ProZone? (Leeds, UK). Sprinting (explosive and leading) was analysed for each playing position. To compare positional differences, a Kruskal-Wallis analysis was performed. Differences were found among positions for total number of sprints and total sprint distance covered: wide midfielders > (attackers = wide defenders) > central midfielders > central defenders (P < 0.001), as well as for explosive sprints: (wide midfielders = attackers = wide defenders) > central defenders, wide midfielders > central midfielders > central defenders and attackers = wide defenders = central midfielders (P < 0.001), and leading sprints: wide midfielders > (attackers = wide defenders) > central midfielders > central defenders (P < 0.001). For each group, there were no differences in ratio of explosive to leading sprints. Wide midfielders performed a higher number of sprints in all five distance categories than all other positions. This study showed that sprinting characteristics are influenced by position. Wide midfielders have to complete additional high-intensity activities during training sessions compared with the other positions to achieve the performance level required during the match.

Growth,functional capacities and motivation for achievement and competitiveness in youth basketball: an interdisciplinary approach

The interaction of multiple influences on the path to sport success is not yet fully understood by sport scientists. In this study, we examined variation in body size, functional capacities and motivation for achievement, competitiveness and deliberate practice of youth basketball players associated with differences in biological maturity status, chronological age and years of training experience. Reflecting the importance of interactive effects, we examined the relationships between the psychological variables and functional capacities. Fifty-eight male basketball players aged 9.5 to 15.5 years were considered. Variables included chronological age, estimated age at peak height velocity, stature, body mass and sitting height by anthropometry; the Work and Family Orientation and Deliberate Practice Motivation Questionnaires were also used. Finally, the Line Drill test and Yo-Yo Intermittent Recovery level 1 (Yo-Yo IR1) tests were used as functional capacities indicators for basketball. Variance components models derived from series of multilevel linear regression models revealed a substantial variation by maturity status for body size, functional capacities indicators, mastery and will to excel. The influence of estimated maturity status on mastery and will to excel was independent of age and years of experience. In contrast, no relationships were observed between psychological variables and functional capacities indicators. We conclude that growth-related changes are relevant to understanding players´ motivations for achievement, competitiveness and deliberate practice. This should be of interest to those involved in the selection and development of youth basketball players.     

Determinants and patterns of physical activity practice among Spanish university students

The purpose of the present study was to investigate the socio-demographic and lifestyle determinants of physical activity practice, as well as the motivations for being or not being physically active in Spanish university students. A representative sample of students from a Spanish university (n = 2,051; 42.1% males; mean age 21.9, s = 4.8 years) participated in the present cross-sectional study. A questionnaire including questions regarding lifestyle, dietary habits, parents' characteristics, and physical activity habits was administered to the students. The socio-demographic and lifestyle determinants of physical activity practice were assessed using multivariable logistic regression. 68.4% of men and 48.4% of women reported to practise physical activity in the present sample. Those who practised physical activity consumed more fruits and were less likely to be smokers compared to non-physically active students. Also, physically inactive men spent more time in front of the computer and physically inactive women spent more time in front of the TV and were more likely to be frequent alcohol consumers. Maternal educational level and maternal physical activity habits were also important determinants of physical activity practice among men and women respectively. In conclusion, physically active students tended to engage in other healthy habits in the present population, suggesting the clustering of healthy or unhealthy lifestyle factors among specific subgroups.     

Co-operative production and technical education in the Basque Country

Conclusion In synthesis, we cannot assert that a complete process of learning, doing and creating is occurring at the EPP because its development is necessarily constrained by the dominant larger society as well as its internal contradictions. In spite of that, on the basis of the democratic mode of operation of the co-operatives and the EPP, and on the incipient process of technical education (bodily exercise, mental instruction and technological training) combined with paid productive labour, it seems that at Mondragón's EPP a significant step is being taken towards an effective process of appropriation of knowledge. In this framework, students of the EPP, members of Alecoop, are creating the necessary conditions to become fully developed individuals.
