针对消费者绿色偏好异质性而引发产品需求不确定性的情形,构建了基于混合CVaR准则的绿色供应链双层风险决策模型,研究了一个具有不同风险态度制造商与一个具有不同风险态度零售商所组成供应链的最优绿色研发投入及广告宣传水平等决策问题,分析了成员不同风险态度对供应链相关决策的影响。在此基础上,提出一个基于风险补偿的双向成本分担契约协调机制,并给出实现供应链协调的合理转移支付区间,最后通过数值分析验证该协调机制的有效性。结果表明,无论供应链成员表现为何种风险态度,该契约均能实现供应链协调,并且对由风险规避制造商与风险追逐零售商所组成的供应链协调效果最为显著。  相似文献

考虑由新能源汽车租赁企业和政府组成的二级系统,在需求率为随机且与推广努力水平相关的市场环境下,建立了新能源汽车租赁企业和政府之间的博弈模型,探讨了分散决策、集中决策、收益共享与成本共担契约下的最优车队配置和推广努力水平,并对三种情形下的最优决策进行了比较和分析。研究结果表明:在分散决策情况下无法实现系统协调,通过引入成本共担与收益共享组合契约,当契约参数满足一定条件时,该组合契约模型不仅可以实现系统协调而且可以使系统成员达到帕累托改进。最后通过算例分析,验证了模型了可靠性和有效性。  相似文献

Background

Prenatal health promotion provides information regarding pregnancy risks, protective behaviours and clinical and community resources. Typically, women obtain prenatal health information from health care providers, prenatal classes, peers/family, media and increasingly, Internet sites and mobile apps. Barriers to prenatal health promotion and related services include language, rural/remote location, citizenship and disability. Online public health platforms represent the capacity to reach underserved women and can be customised to address the needs of a heterogeneous population of pregnant women.

Aim

Canadian government-hosted websites and online prenatal e-classes were evaluated to determine if accessible, inclusive, comprehensive and evidence-based prenatal health promotion was provided.

Methods

Using a multijurisdictional approach, federal, provincial/territorial, municipal and public health region-hosted websites, along with affiliated prenatal e-classes, were evaluated based on four criteria: comprehensiveness, evidence-based information, accessibility and inclusivity.

Findings

Online prenatal e-classes, federal, provincial/territorial and public health-hosted websites generally provided comprehensive and evidence-based promotion of essential prenatal topics, in contrast to municipal-hosted websites which provided very limited prenatal health information. Gaps in online prenatal health promotion were identified as lack of French and multilingual content, targeted information and representations of Indigenous peoples, immigrants and women with disabilities.

Conclusion

Canadian online prenatal health promotion is broadly comprehensive and evidence-based, but fails to address the needs of non-Anglophones and represent the diverse population of Canadian pregnant women. It is recommended that agencies enhance the organisation of website pregnancy portals/pages and collaborate with other jurisdictions and community groups to ensure linguistically accessible, culturally-competent and inclusive prenatal online resources.  相似文献

Institutionalization of health promotion interventions occurs when the organization makes changes to support the program as a component of its routine operations. To date there has not been a way to systematically measure institutionalization of health promotion interventions outside of healthcare settings. The purpose of the present study was to develop and evaluate the initial psychometric properties of an instrument to assess institutionalization (i.e., integration) of health activities into faith-based organizations (i.e., churches). This process was informed by previous institutionalization models led by a team of experts and a community-based advisory panel. We recruited African American church leaders (N = 91) to complete a 22-item instrument. An exploratory factor analysis revealed four factors: 1) Organizational Structures (e.g., existing health ministry, health team), 2) Organizational Processes (e.g., records on health activities; instituted health policy), 3) Organizational Resources (e.g., health promotion budget; space for health activities), and 4) Organizational Communication (e.g., health content in church bulletins, discussion of health within sermons) that explained 62.3 % of the variance. The measure, the Faith-Based Organization Health Integration Inventory (FBO-HII), had excellent internal consistency reliability (α = .89) including the subscales (α = .90, .82, .81, and .87). This measure has promising initial psychometric properties for assessing institutionalization of health promotion interventions in faith-based settings.  相似文献

In care-physical activity (care-PA) initiatives, primary care and sports are combined to stimulate PA among adults at risk of lifestyle related diseases. Preliminary results from Dutch care-PA initiatives for adults with a low socioeconomic status (SES) indicate a decrease in participants’ body weight and an improved quality of life, however, the elements that make these initiatives successful are yet to be identified. In total, 19 Dutch health promotion experts participated in our concept mapping (CM) of the effective elements of care-PA initiatives for adults with a low SES. The experts identified 111 effective elements of these initiatives, which were grouped into 11 clusters, focusing on: 1) approaching participants within the care-PA initiative, 2) barriers experienced throughout the initiative, 3) long-term implementation, 4) customizing the care-PA initiative to the target population, 5) social support, 6) structure and guidance, 7) the professionals within the care-PA initiative, 8) the accessibility of the care-PA initiative, 9) targeted behaviour and progression, 10) recruitment and administration, and 11) intersectoral collaboration. CM was useful for creating a valuable overview of these effective elements. Our results could be used to improve the development and implementation of future care-PA initiatives for adults with a low SES.  相似文献

BackgroundFetal movements are a key indicator of fetal health. Research has established significant correlations between altered fetal activity and stillbirth. However, women are generally unaware of this relationship. Providing pregnant women with information about the importance of fetal movements could improve stillbirth rates. However, there are no consistent fetal movements awareness messages globally for pregnant women.AimsThis study aimed to explore the antenatal care experiences of Australian mothers who had recently had a live birth to determine their knowledge of fetal movements, the nature and source of that information.MethodsAn online survey method was used for 428 women who had a live birth and received antenatal care in Australia. Women’s knowledge of fetal movements, stillbirth risk, and the sources of this knowledge was explored.FindingsA large proportion of participants (84.6%; n = 362) stated they had been informed by health care professionals of the importance of fetal movements during pregnancy. Open-ended responses indicate that fetal movements messages are often myth based. Awareness that stillbirth occurs was high (95.2%; n = 398), although, 65% (n = 272) were unable to identify the current incidence of stillbirth in Australia.ConclusionWomen who received antenatal care have high-awareness of fetal movements, but the information they received was inconsistent. Participants knew stillbirth occurred but did not generally indicate they had obtained that knowledge from health care professionals. We recommend a consistent approach to fetal movements messaging throughout pregnancy which focuses on stillbirth prevention.  相似文献

“秘书问题”是20世纪90年代出现的一个具有特殊含义的词语,主要指存在于部分秘书身上的晋升快、越权干政、贪污腐败和领导权力掮客等负面现象。其实“秘书问题”与领导问题息息相关,与领导权力寻租、权力失控有密切的关系。要解决“秘书问题”,可从加强领导权力制约和运行监管、健全秘书使用监管机制、培育秘书信念道德三条途径入手,关键是有效制约领导权力。  相似文献

This pilot study was conducted in one early childhood pre-school nursery setting in an area of high deprivation in England to explore the under-researched area of how practitioners promote the health of children. The research used an original tool, Child Health Promotion: A Toolkit for Early Childhood Education and Care Practitioners, containing a 5 Step Programme as a model to guide practitioners in identifying and implementing a health promotion activity. The findings will help to set the onward agenda for a larger scale study which will foreground the voices of practitioners and highlight the role that ECEC practitioners can play in promoting the health of children.  相似文献

中国文化推广缺乏学术研究的引领和文化产业的支撑。中国文化推广的战略定位和实施路径应环绕三个枢纽展开:中国文化推广现状,中国文化推广路径,中国文化推广体系;着力解决好四个关键:文化推广路径调研,传统文化精品尤其是哲理思想和世界性理论问题互动,(多模态)影像片创意和精美制作,发展文化产业。只有这样,中国文化推广的春天甚至是夏天才会到来。  相似文献
