In this article we explore what data-based decision making use looks like in schools in five different countries (United Kingdom, Germany, Poland, Lithuania and the Netherlands). We explore for what purposes data are used in these countries and what the enablers and barriers to data use are. The case study results show that schools in all five countries use data for school development, accountability, and instructional improvement. Also, the schools in the five countries struggle with the same type of problems: e.g. lack of access to high quality data, lack of professional development in using data, and a lack of collaboration around the use of data. Finally, we discuss how some enablers can turn into barriers for effective data use. 相似文献

This study examined the presence and strengths of determinants associated with consultation of an in-house expert on child abuse and neglect (CAN) by preventive child health care professionals who suspect CAN. This study also assessed the relationship between in-house CAN expert consultation and professionals’ performance of six recommended activities described in a national guideline on preventing CAN for preventive child health care professionals. A total of 154 professionals met the study’s inclusion criteria. They filled in a questionnaire that measured in-house consultation practices and twelve determinants associated with the professional, the in-house expert, and the organizational context. Bivariate and multivariate regression analyses were performed. Almost half of the participants (46.8%) reported to consult the in-house expert in (almost) all of their suspected CAN cases. Professionals who reported better recollection of consulting the in-house expert (i.e. not forgetting to consult the expert) (p = .001), who were more familiar with consultation (p = .002), who had more positive attitudes and beliefs about consultation (p = .011) and who reported being more susceptible to the behavior (p = .001) and expectations/opinions (p = .025) of colleagues regarding in-house expert consultation were more likely to consult the in-house expert. Furthermore, in-house expert consultation was positively associated with two of six key guideline activities: consulting the regional child protection service and monitoring whether support was provided to families. The implications of these results for improving professionals’ responses to CAN are discussed. 相似文献

The present paper aims at proposing a structured methodology to evaluate the results of an academic training course addressed to postgraduate students. The evaluation process intends to identify the efficacy of an education course by means of a comparison between the general objectives and the results expected by the students. Since the evaluated aspects by the students, detected by means of questionnaires, are both quantitative and qualitative, the proposed methodology is based on the analytic hierarchy process (AHP). In order to facilitate the evaluation process, answers have been modelled by means of linguistic variables. In particular, different evaluation scales have been used and each one is characterized by different levels associated to different fuzzy numbers. 相似文献

智慧城市信息安全风险评估模型构建与实证研究 总被引:1,自引:0,他引:1
[目的/意义] 面对智慧城市日益突出的信息安全问题,提出一个科学的风险评估模型,以快速对智慧城市进行风险分类并分析风险因素。[方法/过程] 从智慧城市信息安全的5个层次和风险评估的4个主要因素出发,构建智慧城市信息安全风险指标框架,对智慧城市实例进行ward系统聚类形成分类属性,选择C4.5算法的决策树方法建立风险评估模型,并验证模型的科学性。[结果/结论] 结果发现:安全管理制度、数据泄露与损坏威胁、安全意识薄弱性和设备安全漏洞是智慧城市之间差距最显著的风险因素,根据评估结果提出保障智慧城市信息安全的建议。 相似文献

随着我国高等教育事业的发展,高校财务活动已不再是简单的取得财政、事业收入,拨缴规定款项,和核算相关支出。作为会计主体,高校会计核算的内容正逐步走向多样化、复杂化。鉴于这种情况,应尽快在高校财务报表体系中增加现金流量表,全面反映一个学校一定会计期间现金流入、流出和净增加(减少)情况,以改变现行高校会计信息披露不完整,决策依据不充分的现状。 相似文献

儒家“立德立功”观与大学生的理想教育 总被引:1,自引:0,他引:1
儒家把立德立功、为国为民谋利作为评判个体有无价值的重要依据,并以此为人生的不朽追求。个体正确价值观的养成对个体的发展意义重大。重温儒家立德立功思想及相应的培训方法,对当今大学生的理想教育具有重要启示。 相似文献
