The domestic dog is an ideal model species in which to study the genetic and environmental factors that influence play behavior. Dogs exist in a wide variety of breeds and frequently engage in multiple forms of play. In the present study, we investigated whether the levels of solitary and social play differed between dogs of three breed types with distinct predatory motor pattern sequences (herding dogs, retrievers, and livestock guarding dogs [LGDs]). Furthermore, we investigated how environmental factors (social and nonsocial contexts) influenced play in dogs of these breed types. Groups of breed-matched dyads with working experience and of equivalent age, sex, and neuter status ratios were exposed to four experimental test conditions and two control conditions in randomized orders. With respect to solitary play, environmental context did have a significant effect, with toys reliably producing the highest levels of solitary play across all breed types. Retrievers engaged in significantly higher levels of solitary play overall than LGDs, and there was a trend in comparison to herding dogs. In contrast, neither environmental context nor breed had a significant effect on social play levels; however, neuter status of the dyads did have a significant effect on social play, with mixed-status dyads engaging in significantly higher levels of social play than same-status dyads. Our findings provide experimental evidence for identifying proximate, environmental stimuli that reliably facilitate social and solitary play and discuss possible genetic (i.e., breed type) and lifetime influences on the form of play in domestic dogs. 相似文献

This study examines associations between childhood maltreatment and developmental trajectories of sexual risk behaviors (SRBs) in a sample of 882 sexually active adolescent girls, predominantly Hispanic or Black, assessed every 6 months between 13 and 23 years. Latent profile analyses revealed four distinct maltreatment profiles: Low Maltreatment (76%), Moderate Emotional Neglect Only (15%), Severe Physical/Emotional Abuse (3%), and Severe Sexual Abuse (6%). Multilevel growth analyses showed the Moderate Emotional Neglect Only and Severe Sexual Abuse profiles exhibited more SRBs starting in late adolescence, and the Severe Sexual Abuse profile also exhibited a faster increase than the Low Maltreatment profile. Understanding heterogeneity within maltreated populations may have important implications for healthy sexual development. 相似文献

National and international legislation has increasingly placed a duty on professionals to consult with young people about matters affecting their lives. Consequently, conducting consultation exercises with young people in order to improve the quality of services available is becoming established practice in many areas. Following on from previous research which asked children and young people about ways they prefer to be consulted, this study developed a new model of consultation to enhance the effectiveness of meetings that young people attend in order to discuss their additional support needs. This model was implemented in a series of consultation meetings in three secondary schools, and was evaluated by examining the views of the key stakeholders (pupils, parents, school staff, visiting professionals) through questionnaires and interviews. The findings suggest that this new model did have a positive impact on the young people who were involved and was perceived positively by all stakeholder groups. This model can provide guidance for EPs and other professionals who wish to effectively involve children and young people in the consultation process. 相似文献

The placement in and movement among preschool programs of 131 children with severe and profound hearing losses was monitored over four years. Longitudinal data were obtained on the children's linguistic and social development. In the first year of the study, most of the children were enrolled in auditory/oral (A/O) programs. By the final year, most were enrolled instead in total communication (TC) programs; similar movement occurred from individual to classroom programs. Children in A/O individual programs had the most hearing, highest intelligence and most favorable family profile, followed by children in A/O classes, TC individual programs, and TC classes. Scores on measures of spoken language followed the same pattern. On measures of receptive language and mother-child communication, children in A/O individual programs and those in TC classes had similar scores. Children in TC individual programs came next, and last were children in A/O classes. These findings have implications for the choice of programs for preschool deaf children. 相似文献

Trends in Higher Education Participation in Scotland 总被引:1,自引:0,他引:1
Lindsay Paterson 《Higher Education Quarterly》1997,51(1):29-48
Scottish higher education has expanded and diversified in the last two decades. Most notably, compared to the early 1980s, participation in the mid-1990s has risen disproportionately among people aged over 21, people from socially disadvantaged backgrounds, women, and (probably) minority ethnic groups. Students are more likely to move away from their home region on entering undergraduate courses, although they are not much more likely than before to leave Scotland altogether. Although participation from Scotland generally has risen more rapidly than participation from elsewhere in the UK generally, at some Scottish institutions the proportion of undergraduates coming from outside Scotland is growing. The system as a whole is not becoming markedly more part-time, although there has been a rise in the very small proportion of people who are studying for first degrees part-time (as opposed to HNDs etc). The share of higher education taking place in further education colleges has grown sharply, but nearly all of that has been for HNDs etc rather than degrees. The expansion has been driven partly by general social change (including the intergenerational effects of previous educational expansion), partly by special entrance schemes to encourage students from social backgrounds that have not in the past been strongly associated with entering higher education, and partly by government policy. These pressures will continue, and will probably be reinforced by the imminent reform of post-16 assessment and curriculum in Scotland, producing for the educational stage immediately preceding higher education for most students a unified framework embracing both academic and vocational courses. 相似文献

ABSTRACTCollections care describes actions taken to prevent or limit the deterioration of moveable cultural heritage and ‘collections care documentation’ (CCD) refers to the recording and retention of information relating to those activities. This paper describes the findings of a survey and targeted interviews with staff from a number of U.K. museums, archives and libraries. The results suggest that, while there is much good practice, some organisations face difficulties instituting a framework for CCD which covers all their activities effectively.Large and small organisations have varying challenges to face; the former with specialist staff working in separate departments and the latter with staff who carry out activities relating to preventive conservation but who may not have specialist knowledge. An efficient documentation structure, which is resilient and relevant to the organisation, can support and improve communication as well as raise awareness of the reasons for and methods of preventive conservation. This paper looks at the reasons why even basic practices can sometimes be difficult to achieve and presents ideas for identifying and overcoming barriers. As preventive conservators argue that specified actions influence the long-term sustainability of collections the evidence that allows verification those claims needs to be retained. In order to do this, a greater focus on what data to collect and why will enable the sector to align CCD with specific research questions. 相似文献

Using a cohort of 310 low‐income male adolescents living in an urban community and followed prospectively from 18 months through adolescence (ages 15–18 years), the current study examined whether individual, family, and community risk factors from ages 18 to 42 months were associated with adolescents' violent behavior, as indexed by juvenile petitions. Results of multivariate analyses indicated that although family income was the only factor to discriminate those with no arrest record from those with nonviolent arrests, rejecting parenting, child oppositional behavior, emotion regulation, and minority status during the toddler period contributed unique variance in distinguishing male adolescents arrested for violent behavior compared to those never arrested and those arrested for nonviolent behavior. Implications for prevention efforts are discussed. 相似文献

The Long-Term Effects of Parental Divorce on the Mental Health of Young Adults: A Developmental Perspective 总被引:8,自引:0,他引:8

The effects of parental divorce during childhood and adolescence on the mental health of young adults (age 23) were examined, using the National Child Development Study (NCDS), a longitudinal, multimethod, nationally representative survey of all children born in Great Britain during 1 week in 1958 ( N = 17,414). Children were assessed at birth and subsequently followed up at ages 7, 11, 16, and 23 by means of maternal and child interviews, and by psychological, school, and medical assessments. Parental divorce had a moderate, long-term negative impact on adult mental health, as measured by the Malaise Inventory total score, and controlling for economic status, children's emotional problems, and school performance preceding marital dissolution. The likelihood of scoring above the clinical cutoff of the Malaise Inventory rose from 8% to 11% due to parental divorce. This indicated that the relative risk of serious emotional disorders increased in the aftermath of divorce, but that the large majority of individuals did not exhibit such risks. Path analyses revealed that the negative effects of divorce on adult mental health operated indirectly through higher emotional problems and lower levels of school achievement and family economic status at age 16. Results related to timing of divorce, remarriage, and interactions between age 7 emotional problems and divorce, and between age 7 emotional problems and child gender, are also discussed. 相似文献
