Handedness data of the Japanese were collected twice with an interval of 20 years, using an identical handedness inventory. In the second cohort, non-right-handers among male and female students numbered 11.5% and 5.9%, respectively. The results showed that the incidence of non-right-handedness among Japanese females has increased from 20 years ago.  相似文献

SUMMARY

The library Web site is a significant access point to a library's collections, resources, and services. A Web site can and should provide information about the library in a way that can be efficiently navigated and used by all library patrons. The usability of a library Web site can be improved through changes in organization and design informed by the experiences of real users. User expectations should be primary in determining the content, purpose, organization, and design of the site.  相似文献

Summary

Female adolescents entering the juvenile justice system have complex and serious problems in multiple areas of adjustment. Literature is reviewed on the prevalence and form of antisocial behavior in girls and on the long-term implications of such problems in adolescence. Risk factor characteristics, including family fragmentation, physical and sexual trauma, mental health problems, official arrest and self-report offending histories of a population of girls referred for out-of-home placement because of repeated and chronic juvenile offending are presented. In addition, with the exception of sexual trauma histories, these sample characteristics are compared to a similar sample of chronically offending boys. A treatment approach is described and pilot data are presented on its feasibility. Implications for designing empirically-based, gender-related treatment models are discussed.  相似文献

Bouncing Back     
Seventy-five students with mild disabilities were monitored in reading and math immediately before and after a summer vacation and six weeks into the following school year using Curriculum- Based Measurement probes. Results indicated that students regressed significantly in both academic areas following the summer break, however, by the time of recouprnent measuremen4 students had regained proficiency and, in reading, were performing significantly above their spring scores. Students were performing at the same level in math at the recwpment time as they were at spring. Implications for policy and practice are discussed.  相似文献

This article describes the evaluation of the Arkansas Act 1220 of 2003, a comprehensive legislative proposal to address the growing epidemic of childhood obesity through changes in the school environment. In addition, the article discusses specific components of the evaluation that may be applicable to other childhood obesity policy evaluation efforts. The conceptual framework for the evaluation, research questions, and evaluation design are described, along with data collection methods and analysis strategies. A mixed methods approach, including both quantitative (surveys, telephone interviews) and qualitative (key informant interviews, records reviews) approaches, was utilized to collect data from a range of informant groups including parents, adolescents, school principals, school district superintendents, and other stakeholders. Challenges encountered with the evaluation are discussed, as are strategies to overcome those challenges. Now in its 9th year, this evaluation has documented substantial changes to school policies and environments but fewer changes to student and family behaviors. The evaluation may inform the methods of other evaluations of childhood obesity prevention policies, as well as inform policymakers about how quickly they might expect implementation of such policies in their own states and localities and anticipate both positive and adverse outcomes.  相似文献

Designers acknowledge that their skills can assist the visualization and materialization of a desirable future and have gone as far as proposing that design can achieve societal change. Designing for a better world is associated with decreasing environmental depletion impacts while making good for both people and the environment, if possible. Evidently, this is a space where design deals with ethical matters, defining what is good or questioning if good has a universal meaning. This paper discusses the case of Aalto LAB Mexico's (ALM) Eco-hostel project, a practical and ethical design exploration. It shares the impressions of the design team when co-designing with(in) the Mayan community of ‘20 de Noviembre’ (20 Nov), located in Calakmul, Campeche, México. The Eco-hostel project was proposed as an element which can play a central role in achieving betterment of several aspects of the community's daily life. Several of those aspects were communicated by the inhabitants of 20 Nov, and some others were identified by ALM's experts. Whereas some universal principles were applicable to the construction, the context-centred approach of ALM generated a unique proposal, conceptualized to achieve harmony with the local environmental and cultural conditions.  相似文献

We investigated 4th-grade children’s search strategies on sequential search tasks in which the goal is to identify an unknown target object by asking yes–no questions about its features. We used exhaustive search to identify the most efficient question strategies and evaluated the usefulness of children’s questions accordingly. Results show that children have good intuitions regarding questions’ usefulness and search adaptively, relative to the statistical structure of the task environment. Search was especially efficient in a task environment that was representative of real-world experiences. This suggests that children may use their knowledge of real-world environmental statistics to guide their search behavior. We also compared different related search tasks. We found positive transfer effects from first doing a number search task on a later person search task.  相似文献

John Arbuthnot's celebrated but flawed paper in the Philosophical Transactions of 1711–12 is a philosophically and historically plausible target of Hume's probability theory. Arbuthnot argues for providential design rather than chance as a cause of the annual birth ratio, and the paper was championed as a successful extension of the new calculations of the value of wagers in games of chance to wagers about natural and social phenomena. Arbuthnot replaces the earlier anti-Epicurean notion of chance with the equiprobability assumption of Huygens's mathematics of games of chance, and misrepresents the birth ratio data to rule out chance in favour of design. The probability sections of Hume's Treatise taken together correct the equiprobability assumption and its extension to other kinds of phenomena in the estimation of wagers or expectations about particular events. Hume's probability theory demonstrates the flaw in this version of the design argument.  相似文献

植入性医疗设备安全技术有了长足发展,但仍存在技术设计与患者价值需求相矛盾,技术上可行的设备往往不为患者所接受等问题.植入性医疗设备的安全设计既应具备理想的技术性能,也应充分考虑患者的价值诉求.价值敏感设计是一种关于技术设计的理论方法,对患者的价值观和伦理道德心理诉求予以关注,为以植入型心脏转复除颤器为代表的植入性医疗设备的安全性设计提供方法指导和建议,对我国植入性心脏转复除颤器的设计和应用具有重要的借鉴意义.  相似文献

Editorial     
The aim was to investigate organizational impact on working conditions and to explore the associations between sector, different types of organizational change, and working conditions. A strategic selection was made of representative staff members from 72 work sites. Data pertaining to organizational factors were collected from managers, and to working conditions from employees. Multilevel analyses were performed, with 10 aspects of self-reported and expert assessed psychosocial and ergonomic/physical working conditions as the dependent variables, and patterns of organizational change and sector as the explanatory variables. The results showed that the variance in working conditions was significantly attributed to organizational level (16?–?65% of the variance), and that both the pattern of change and the sector were important. Organizations that had not undergone change provided the best work conditions. The “standardizing” and “market-adjusting” patterns of change had deleterious effects, while the “lean” and “centralizing” patterns led to dual outcomes. Organizational change was perceived as having more negative consequences in the public sector than in the private sector. The results indicate that organizational change contributes to increased differentiation of working conditions, as different types of changes congregate in specific areas of the labour market and affect groups of employees differently.  相似文献
