Sexual attraction (SA), the earliest stage of sexual orientation, is scarcely studied. This prospective study examined, over 3 years, prevalence, changes in SA, and the role of context, among 946 Puerto Rican youth, aged 11–13 years at initial assessment in the South Bronx (SBx), New York City, and Puerto Rico (PR). Overall, 98.1% of boys and 95.3% of girls reported opposite-sex only SA at some point, whereas 13.8% of girls and 12.0% of boys reported any-same SA. Opposite-sex only SA increased over time, whereas other SAs decreased except for any same-sex SA among SBx girls. Girls in the SBx and younger youth in PR reported more any same-sex SA. Context and culture may play a role in the developmental trajectories of adolescents’ SA.  相似文献

Efficacy of Cognitive‐Behavioral therapy in the treatment of children with adhd,with and without aggressiveness     

Ana Miranda  María Jesús Presentacin 《Psychology in the schools》2000,37(2):169-182

The objectives of this study were twofold: to show the efficacy of a cognitive‐behavioral self‐control therapy on children with ADHD and to determine whether the combination of training in self‐control with training in anger management has better outcomes on two subgroups of hyperactive children, aggressive and nonaggressive. Thirty‐two children with ADHD, 16 aggressive and 16 nonaggressive, participated in the research. We applied a cognitive‐behavioral self‐control training, which included self‐instructional training via modeling and behavioral contingencies, to 16 of the 32 hyperactive children. The other 16 hyperactive children were taught the same program, but combined with anger management training. The interventions were carried out by two therapists each taking care of four groups, one of each in the following conditions: hyperactive with the cognitive‐behavioral self‐control therapy, hyperactive with the combined treatment, hyperactive‐aggressive with the cognitive‐behavioral self‐control therapy, and hyperactive‐aggressive with the combined treatment. The results indicated important improvements on several measures in all treated groups. Furthermore the improvements of children with aggressiveness were slightly better, according to the parents, with the combined treatment than without it. The data provide support for including anger management training in the cognitive‐behavioral interventions for hyperactive‐aggressive students. © 2000 John Wiley & Sons, Inc.  相似文献   

Menstrual cycle alters training strain,monotony, and technical training length in young     

Gislaine Cristina-Souza  Ana C. Santos-Mariano  Carla C. Souza-Rodrigues  Raul Osiecki  Sandro F. Silva  Adriano E. Lima-Silva 《Journal of sports sciences》2019,37(16):1824-1830

The menstrual cycle (MC) phases carry to several psychophysiological alterations; however, no study has investigated the impact of MC phases on training load or technical training. In the present study, we investigated the effect of the follicular phase (FP), ovulatory phase (OP), and luteal phase (LP) on training load and technical training in young athletes. Twelve female athletes performed regular daily training sessions with the rating of perceived exertion (RPE) and duration being registered every session. Training impulse (TRIMP), monotony and strain were calculated. MC symptoms, RPE, and duration were also measured during technical training, which was carried out on a specific day during each phase. The TRIMP was not affected by MC phases during regular training (p > .05), but training monotony and strain were higher in FP compared to OP (p < .05). During the technical training, MC phases did not affect RPE (p > .05), but the session was longer in both FP and LP, compared to OP (p < .05). MC symptoms were exacerbated in FP compared to both OP and LP (p < .05). These findings suggest that MC disorders were elevated during FP, which indicate that monitoring MC phases might provide important feedbacks for programming training and expected results during competitions.  相似文献   

‘Bloomers’ and the British World: Dress Reform in Transatlantic and Antipodean Print Culture, 1851–1950     

Ana Stevenson 《Cultural and Social History》2017,14(5):621-646

The ‘bloomers’ are rarely considered beyond their 1851 origins in the United States and subsequent appearance in Britain. This article expands dress reform scholarship by analysing print culture elsewhere in the British world, specifically Australia and New Zealand. The colonial press manufactured controversy over this fashion – a perceived transgression of gender norms – even though antipodean women rarely sported the outfit. This article focuses on the dress reform lectures and writings of Amelia Bloomer, Caroline Dexter and Dr Mary Walker. While certain continuities resurfaced alongside the bloomer-like rational dress popularised in the bicycling culture of the 1890s, dress reform was largely deemed far less controversial by the turn of the twentieth century.  相似文献   

Critic power or star power? The influence of hallmarks of quality of motion pictures: an experimental approach     

Ana Suárez-Vázquez 《Journal of Cultural Economics》2011,35(2):119-135

Most research into the film industry focuses on aggregate level market analysis of a range of devices used by the industry to ensure the success of its films. In contrast, in this paper, we experimentally test how individual cinema-goers are influenced by two variables that have aroused considerable interest in the literature: critical reviews and the role of box office stars. As regards the former, the results of our experiment indicate that negative reviews by film critics are cues that affect cinema-goers’ pre-film assessment of a film yet fail to exert any effect on post-film assessment. As regards the latter, a cast of box office stars is not seen to be an indication of quality per se for our experimental subjects. Nor do box office stars help to mitigate the potential effects of negative reviews.  相似文献   

Risk assessment: A comparative study of archive storage rooms     

Ana Catarina Pinheiro  Maria Filomena Macedo 《Journal of Cultural Heritage》2009,10(3):428-434

The goal of preventive conservation is to provide the correct maintenance of our cultural heritage in order to enrich our future. The Canadian Museum of Nature developed a risk model for preventive conservation that has proven useful in application to a Portuguese archive. This work applies this model to compare the magnitudes of specific risks estimated for this same archive collection when located in either of two pairs of storage rooms. These rooms are in two different parts of this building: two are in an older part and two are in a recent addition. It was, therefore, necessary to assess the building itself, both structurally and environmentally, as well as analyse its common human practices. In terms of the overall risk magnitude, the best room was found to be in the recent building and the worst in the older building. However, risks related to water problems were found to be higher in the new building. In this work cost-free measures and easy to implement recommendations are given in order to improve the quality of the storage rooms. A final comment on the method itself is also given.  相似文献
