目的：探讨应用智能手机运动软件监控体力活动对日常体力活动的影响及其内在机理。方法：选取广州市年龄35~45岁之间的白领38名作为研究对象，实验前、后受试者填写《国际体力活动问卷长卷》问卷，实验中受试者采用动动健康软件管理目标体力活动量，并将每日活动量反馈给监督者，监督者根据受试者上一周的体力活动量，对每名受试者设定下周的目标体力活动量，要求每周活动量较上周增加20%，实验共为期12周。结果：与实验前比较，试验后后第1周、第4周、第8周和12周的步数、能量消耗和活跃时间均非常显著性的增加（P<0.01）；试验后各时间段步数均有所增加，其中，实验前工作日和休息日在17:30-20:00时间段步数最多，试验后工作日步数最多出现在20:00-22:00和17:30-20:002个时间段，休息日出现在8:30-12:00和20:00-22:002个时间段。结论：应用智能手机运动软件进行自我监控可以提高白领日常体力活动量，特别是交通和闲暇时间体力活动。目标设定、自我监控和表现反馈可能是体力活动干预中较为有效的行为改变技术（BCTs）。  相似文献

An alternative to fortified schools: Using crime prevention through environmental design (CPTED) to balance student safety and psychological well-being     

Daniel Lamoreaux  Michael L. Sulkowski 《Psychology in the schools》2020,57(1):152-165

In response to tragic school shootings, heightened attention has been devoted to making schools safer through the implementation of security features. However, excessive security measures have a negative impact on school climate, student functioning, and academic achievement. Therefore, there is a critical need to design schools that are safe and secure, yet also welcoming and comfortable. As a promising approach in this regard, crime prevention through environmental design (CPTED) is an architectural philosophy that aims to deter criminal or antisocial behavior through environmental design, and it includes a focus on natural surveillance, access control, and territorial reinforcement. This review discusses pertinent effects of the school environment on student outcomes, extant research on the impact of visible security measures, the relationship between students’ perceptions of safety and academic functioning, and how using CPTED could concomitantly address the physical safety and psychological comfort of students at school.  相似文献   

Reflective practicum in higher education: the influence of the learning environment on the quality of learning     

Andreina Bruno  Giuseppina Dell’Aversana 《Assessment & Evaluation in Higher Education》2018,43(3):345-358

Sustaining students in becoming reflective practitioners is considered as a valued outcome of higher education. The paper aims to evaluate the impact of the learning environment conditions inspired by Schön’s theory of reflective practicum, by discussing a case study of a master’s degree class. The learning environment was designed to sustain reflective practice and meaningful engagement through professional practice simulation, problem-based learning and reflective writing. Unlike much of the research into reflective learning, the quality of learning was evaluated by assessing the use of reflective practice in students’ weekly journaling, rather than measuring students’ satisfaction or perceptions of effectiveness. Two hundred and six journal entries of 23 students were assessed and used in a quantitative analysis based on a linear mixed-effects model. Findings indicated that the reflective practicum has an incremental effect on students’ reflective practices and that reflective practice is dynamic and sensitive to specific learning environment conditions. In conclusion, students’ co-responsibility of the learning environment allowed by the professional practice simulation appears to foster meaningful and reflective learning. Conversely, conditions that stimulate only cognitive engagement have little impact or even inhibit reflective practices. Practical implications of the use of reflective journal are discussed.  相似文献   

Experimental research in school psychology internationally: An assessment of journal publications and implications for internationalization          下载免费PDF全文

John C. Begeny  Rebecca A. Levy  Rahma Hida  Kate Norwalk 《Psychology in the schools》2018,55(2):120-136

Past studies have examined the contents of journal articles in school psychology, and more recently there has been increased interest in examining the frequency and characteristics of experimental studies appearing in school psychology journals. However, no prior studies have examined the international representation of experimental and intervention studies. This study evaluated every article published from 2002 to 2016 across eight school psychology journals that publish international scholarship. Several research questions were addressed (e.g., what is the frequency of experimental research internationally, what are the characteristics of those studies, and is the scholarship consistent with the global geography of school psychology?). Overall, findings revealed that although the field of school psychology is arguably international, the experimental research reflected in the eight journals selected for review does not adequately represent the global geography of the field, thereby also suggesting that the degree of internationalization in school psychology is relatively poor. The importance of these and related findings is discussed, and recommendations are provided that may help to improve the geographical representation of experimental research in school psychology as well as its overall internationalization.  相似文献   

The effect of altering loading distance on skeleton start performance: Is higher pre-load velocity always beneficial?     

Steffi L. Colyer  Keith A. Stokes  James L. J. Bilzon  Danny Holdcroft 《Journal of sports sciences》2018,36(17):1930-1936

Athletes initiating skeleton runs differ in the number of steps taken before loading the sled. We aimed to understand how experimentally modifying loading distance influenced sled velocity and overall start performance. Ten athletes (five elite, five talent; 67% of all national athletes) underwent two to four sessions, consisting of two dry-land push-starts in each of three conditions (preferred, long and short loading distances). A magnet encoder on the sled wheel provided velocity profiles and the overall performance measure (sled acceleration index). Longer pre-load distances (12% average increase from preferred to long distances) were related to higher pre-load velocity (r = 0.94), but lower load effectiveness (r = ?0.75; average reduction 29%). Performance evaluations across conditions revealed that elite athletes’ preferred distance push-starts were typically superior to the other conditions. Short loading distances were generally detrimental, whereas pushing the sled further improved some talent-squad athletes’ performance. Thus, an important trade-off between generating high pre-load velocity and loading effectively was revealed, which coaches should consider when encouraging athletes to load later. This novel intervention study conducted within a real-world training setting has demonstrated the scope to enhance push-start performance by altering loading distance, particularly in developing athletes with less extensive training experience.  相似文献   

基于环境因素对中国软件产业集群效率的地区差异研究          下载免费PDF全文

廖名岩  曹兴  屈静晓 《科研管理》2018,39(4):74-82

摘要：将四阶段DEA模型引入到软件产业集群效率的研究框架中，以2013年中国国家级35个软件产业园的数据为样本，测算了软件产业集群的技术效率、制度效率和规模效率。研究发现：外生环境因素对软件产业集群效率具有促进作用，这导致中国软件产业集群效率存在被高估的现象；控制考虑环境因素影响后，绝大多数软件园的技术效率均有所下降（32个，91.43%）；对调整后的技术效率进行分解发现，大多数软件园（23个，65.17%）的技术效率无效源于纯技术无效，这进一步说明，代表着决策与管理水平的制度效率不高是制约中国软件产业集群效率提升的主要因素。东部软件园应该以合理安排资源配置、加强制度创新、技术创新、研发创新等科学化等措施为软件园建设的侧重点。中西部软件园应该加大规模投入力度，充分吸收东部投入要素的冗余。  相似文献
