Poor quality of care may have a detrimental effect on access and take-up and can become a serious barrier to the universality of health services. This consideration is of particular interest in view of the fact that health systems in many countries must address a growing public-sector deficit and respond to increasing pressures due to COVID-19 and aging population, among other factors. In line with a rapidly emerging literature, we focus on patient satisfaction as a proxy for quality of health care. Drawing on rich longitudinal and cross-sectional data for Spain and multilevel estimation techniques, we show that in addition to individual level differences, policy levers (such as public health spending and the patient-doctor ratio, in particular) exert a considerable influence on the quality of a health care system. Our results suggest that policymakers seeking to enhance the quality of care should be cautious when compromising the level of health resources, and in particular, health personnel, as a response to economic downturns in a sector that traditionally had insufficient human resources in many countries, which have become even more evident in the light of the current health crisis. Additionally, we provide evidence that the increasing reliance on the private health sector may be indicative of inefficiencies in the public system and/or the existence of features of private insurance which are deemed important by patients. 相似文献

激励在复杂产品供应链中对主供协同合作关系及质量控制发挥了重要作用。本文研究基于主制造商在复杂产品生产研发前按照客户要求形成的质量意识的激励策略是否可以实现复杂产品质量控制问题。考虑具有质量意识的主制造商和其系统供应商组成的两级供应链,建立以主制造商为领导者的Stackelberg博弈模型,分别讨论无激励和存在激励时的主供生产最优决策。基于激励方式的不同,将激励策略分为根据供应商产品质量水平激励以及根据主制造商质量意识水平激励两种方式。研究结果表明激励是供应商加强协同合作、改进产品质量的内在动力,主制造商根据质量意识激励供应商可以进一步促使双方协同合作,提高产品质量,使双方获得更高的利润从而实现供应链整体利润最大化。此外用灵敏度分析发现提高主制造商质量意识水平可以增加双方协同合作努力程度,有效提升产品质量水平并实现帕累托改进。 相似文献

Focusing on migrant social networks, this paper draws upon the sociology of time to incorporate complex notions of temporality into the research process. In so doing, we consider firstly, the challenge of going ‘beyond the snapshot’ in data collection to capture dynamism through time. Secondly, we apply the concepts of timescapes to explore ways of addressing the wider context and the interplay between spatiality, temporality and relationality in migration research. We argue that integrating a mixed methods approach to SNA, crucially including visualisation, can provide a useful methodological and analytical framework to understand dynamics.SNA can also be helpful in bridging the personal and structural dimensions in migration research, by providing a meso level of analysis. However, it is also important to connect the investigation of local and transnational networks with an analysis of the broader social, economic and political contexts in which these take shape; in other words, connecting the micro and the meso with the wider macro level. Drawing upon reflections from our migration research studies, we argue that different combinations of quantitative, qualitative and visual methods do not just provide richer sets of data and insights, but can allow us to better connect conceptualisations – and ontologies – of social networks with specific methodological frameworks. 相似文献

Supporting healthy lifestyle behaviours is a key aspect of preventing type 2 diabetes which disproportionately affects disadvantaged groups from a younger age. Formative participatory research was undertaken to design a program for young Aboriginal people in a remote town in North West Australia with a high level of health needs and relatively few prevention initiatives. Focus groups and advisory discussions with Aboriginal community members were used to determine the nature of the program. The need for a comprehensive program was consistently expressed and limited healthy lifestyle knowledge and difficulties with healthy eating influenced by food environments were noted to be important. With guidance from the Derby Aboriginal Health Service, findings were integrated with previous international research evidence to develop a program tailored to local Aboriginal people aged 15–25 years and refine it after piloting. This 8-session program, ‘Maboo wirriya, be healthy’ involved an education component consistent with the US Diabetes Prevention Program and practical activities including group exercise. Changes to program structure and documentation were made after piloting for future use. The community-directed approach used in this study is vital to ensure relevance of localised chronic disease prevention programs in a range of settings. 相似文献

ABSTRACTThe use of pop culture sources in social work education enhances the learning of MSW students in the human behavior, policy and diversity courses. Pop culture sources can enhance learning because of the potential for a quicker recall of content, revealing hidden talents and sophisticated understanding of the concepts, and making the assignments more enjoyable for students. However, the impact of utilizing pop culture sources among MSW students in research courses remains unknown. It is imperative that contemporary teaching modalities be implemented in research courses because MSW students have mixed feelings about taking research classes and conducting research of their own. The purpose of this article is to report findings of the implementation of a pop culture source-analyzing song lyrics-in an introductory MSW research class at one university in the USA. Qualitative and quantitative data were collected from (N = 17) MSW students. Findings lend support to utilizing the song lyrics exercise, as students reported enhanced self-efficacy and knowledge of the research process. Future research should assess the impact of this activity with larger samples. 相似文献

Problem
Pacific Islanders are disproportionately burdened by poorer maternal health outcomes with higher rates of pre-term births, low birth weight babies, infant mortality, and inadequate or no prenatal care.Purpose
The purpose of this study was twofold: (1) to explore maternal health care providers’ perceptions and experiences of barriers in providing care to Marshallese women, and (2) providers perceived barriers of access to care among Marshallese women. This is the first paper to explore perceived barriers to maternal health care among a Marshallese community from maternal health care providers’ perspectives in the United States.Methods
A phenomenological, qualitative design, using a focus group and in-depth interviews with 20 maternal health care providers residing in northwest Arkansas was chosen.Findings
Several perceived barriers were noted, including transportation, lack of health insurance, communication and language, and socio-cultural barriers that described an incongruence between traditional and Western medical models of care. There was an overall discord between the collectivist cultural identity of Marshallese families and the individualistic maternal health care system that merits further research.Discussion
Solutions to these barriers, such as increased cultural competency training for maternal health care providers and the incorporation of community health workers are discussed. 相似文献9.

AbstractRisk and performance management are at the core of complex bespoke systems (CBSs). CBSs are developed to customer–specified requirements in terms of structure, functionality and conformance. This article examines how risk and performance management are integrated as essential systems in the successful development of projects across multi-organizational functions in complex bespoke system (CBS) organizations. The article argues for the development of a quality management system that consists of two sub-processes: quality control and quality development. Using three case studies from engineering companies, we provide evidence and insights of the way change control, quality development and quality performance are developed in innovating business solutions. 相似文献
