The demand for improved quality of health promotion evaluation and greater capacity to undertake evaluation is growing, yet evidence of the challenges and facilitators to evaluation practice within the health promotion field is lacking. A limited number of evaluation capacity measurement instruments have been validated in government or non-government organisations (NGO), however there is no instrument designed for health promotion organisations. This study aimed to develop and validate an Evaluation Practice Analysis Survey (EPAS) to examine evaluation practices in health promotion organisations. Qualitative interviews, existing frameworks and instruments informed the survey development. Health promotion practitioners from government agencies and NGOs completed the survey (n = 169). Principal components analysis was used to determine scale structure and Cronbach’s α used to estimate internal reliability. Logistic regression was conducted to assess predictive validity of selected EPAS scale. The final survey instrument included 25 scales (125 items). The EPAS demonstrated good internal reliability (α > 0.7) for 23 scales. Dedicated resources and time for evaluation, leadership, organisational culture and internal support for evaluation showed promising predictive validity. The EPAS can be used to describe elements of evaluation capacity at the individual, organisational and system levels and to guide initiatives to improve evaluation practice in health promotion organisations.  相似文献

This paper reviews several traditions in economic research on preferences as well as research on personality traits in personality psychology and lists challenges in both fields. We discuss challenges regarding the measurement of preferences and personality traits, challenges regarding the stability of preferences and traits, and challenges when inferring causality. Additionally, we highlight areas in which we see potential benefits from taking into account methodological approaches or insights from the respective other discipline.  相似文献

This paper represents the development of an innovative and comprehensive model designed to measure public relations excellence within an organizational context. Drawing on established scales of evaluation for public relations practice, researchers propose a measurement model situated within excellence Theory. Through a partnership between the research team and The Alberta Energy Regulator (AER) organization, a case study approach was developed and implemented, highlighting the relationships between organizational culture and communication. The Excellence in Organizational Context model was tested within the AER, using empirical data gathered through in-depth semi-structured interviews and a self-report questionnaire survey conducted with individuals from various identified organizational stakeholder groups. This mixed-method approach was employed to explore and understand the multi-dimensional nature of public relations practice within this organization.Researchers investigated eight dimensions of excellence in this model. Initial findings indicate that the Excellence in Organizational Context model proposed here is a valid and appropriate method for measuring public relations performance when applied as a mixed-method approach for measuring practice and establishing context within an organizational culture. This indicates the need for both organizational, stakeholder, and sector/national level data in confirming relevant benchmarks.  相似文献

在国际经济比较中,可加性和特征性是购买力平价汇总方法应该具备的重要性质。针对新近发展的、基于双边指数所构建的兼具可加性与特征性的多边比较方法———MBC法,本文对其进行了拓展研究,发展出更为完备的MBC法:一方面,鉴于原始极值最优视角下的MBC法主要考虑的是存在较多“奇异”型价格结构的国家双边比较的特征性,为弥补该视角下的MBC法难以实现整体最优的不足,本文从最小二乘和对数最小二乘的视角分别构建MBC法;另一方面,进一步在MBC法中考虑不同双边比较的可靠性差异问题,分别构建多重视角下的加权MBC法,并引入多种权重函数供应用者参考。采用 ICP2011数据的实证研究结果充分说明,多重视角下的MBC法较好地整合了官方GEKS法的特征性优点和 GK法的可加性优点,相比已有满足可加性的方法,MBC法替代偏差最小,是较理想的既适合于实际物量比较、又可用作支出结构分析的方法。实证研究还发现,最小二乘和对数最小二乘视角下的加权MBC法稳健性较好的优点。  相似文献

Aligned with the New Zealand government’s ‘Predator-Free 2050’ target for Aotearoa New Zealand, National Science Challenge: Our Biological Heritage supports research into five distinct ‘novel biotechnological controls’ of exotic wasps. A framing question within this project is which controls are considered ‘socially acceptable’ and thus suitable for further development to control and potentially eradicate introduced wasps? How can the public answer this question without first engaging with complex technologies? Can they develop and express an informed view that still reflects their ‘gut’ reactions and unique positions? To model and explore the views of an ‘informed public’, university students in Māori studies engaged in reflection, writing and mapping activities; choice and ranking exercises; Q Method; and focus group interviews. Amongst the interviewees, Q Method analysis distinguished three ‘factors’, describing unique viewpoints: those who see the potential of biotechnologies, those who are in doubt about them and those in a position of trust in scientists. Overall, the group see potential in new biotechnologies for wasps but are wary of political, economic and social decision-making mechanisms.  相似文献

索洛余额法、随机前沿生产函数法以及数据包络分析方法都没有解决函数的内生性和模型参数的时变性问题,ACF方法克服了这些局限性,对全要素生产率的测度更加准确。本文推导了参数的内生性和时变性问题,基于ACF模型提出了我国的时变参数估计方法,并对我国1990-2017年28个省份的全要素生产率进行重估。研究结果表明,ACF方法对全要素生产率的测度更加准确。从全国来看,资本投入增长对经济增长的贡献度最大,TFP增长对我国经济增长的贡献度正在逐渐下降,劳动投入对经济增长的贡献度相对较弱且波动大。分地区来看,各地区的TFP平均水平有所回落,近年来东北地区的TFP增长率水平最低,2012-2017年均为负值。同时,东北地区的劳动力流失情况较为严重。  相似文献
