Navigating the COVID-19 pandemic in the contingency framework: Antecedents and consequences of public’s stance toward the CDC

This study applied the contingency theory of conflict management to examine how contingency factors influence the public’s perceptual and behavioral responses to COVID-19 and stance toward the Centers for Disease Control and Prevention (CDC). In particular, we tested political ideology as an important individual characteristic variable to examine its roles in the contingency theory framework. The findings revealed that two situational variables (i.e., threat appraisal and attitudes toward CDC) positively influenced the public’s contingency accommodation stance toward the CDC. Furthermore, greater conservatism was significantly associated with lower levels of threat appraisal and more negative attitudes toward the CDC, however it did not influence the stance toward the CDC. Theoretical and practical implications of the findings and directions for future research are discussed.     

Macroeconomic asymmetry in the Eurozone before and after the Global Financial Crisis: An appraisal of the role of the ECB

The launch of the euro in 1999 was assumed to enhance macroeconomic convergence among EMU economies. We test this hypothesis from a comparative perspective, by calculating different indices to measure the degree of macroeconomic dispersion within the Eurozone, the UK and the USA (1999–2019). We use common factor models to produce a single index for each monetary area out of different measures of dispersion. These indices can be used to inform on the degree of optimality of a monetary area. Our results show that macroeconomic dispersion in the Eurozone increased notably even before 2007 and it took significantly longer to return to pre-crisis levels, as compared to the UK and the USA. The paper shows the critical role played by the ECB’s asset purchases programmes in reducing macroeconomic divergences among EMU member states since 2015.     

移动互联网环境下营销资产绩效转化机制研究

营销资产日益受到企业的重视,但在移动互联网环境下,如何转化为企业绩效还没有完整的理论阐释。在分析文献和调研基础上,构建了移动互联网环境下,关系型营销资产和知识型营销资产转化为企业绩效的中介效应模型,并通过某电信运营企业31个省级分公司半年窗口的经营分析数据进行了统计检验。结果表明,移动互联网环境下,两类营销资产都对企业绩效产生正向影响,其中知识型营销资产的影响大于关系型营销资产,企业的技术能力和营销能力中介这两类营销资产对企业绩效的影响。最后讨论了研究意义、不足和未来研究方向。     

生态价值评估制度探究——兼论资产评估法的完善

生态价值评估是指专门机构或专业评估人员按照特定的标准和程序,运用科学的方法和技术手段对人类赖以生存的生态系统及其所提供的生态服务进行货币化的价值评价和判断的行为。由于生态价值评估对提供生态系统服务价值化的信息、制定可持续发展指标体系、实施生态利益补偿、制定合理的生态资源价格等方面具有重大的作用,因此有必要将其上升到制度化的层面,以法律和制度的形式加以规范。构建生态价值评估制度需要从评估主体的确认及法律地位、评估客体的分类和价值类型的选取以及评估方法的选择和发展等方面全面、系统地分析和研究。生态价值评估制度作为一种新型的、特殊的专项资产评估,它的形成和发展也是对资产评估法的重要补充和完善。     

The Saving for Every Child Program in Israel: an overview of a universal asset-building policy

ABSTRACT

In 2017, the Israeli government implemented a universal child development account programme – the Saving for Every Child Program (SECP) – which establishes a personal savings account for every Israeli child and provides monthly deposits until the child turns 18. The SECP has the potential to provide substantial assets when children reach adulthood, but the benefits depend on parents’ investment choices. The unique programme’s nature presents opportunities to learn from its implementation. This paper provides a comprehensive overview of the SECP, its legislative history, early findings from its implementation, and recommendations that may improve programme participation and outcomes across population groups.     

Grading Gems: Appraising the Quality of Research for Social Work and Social Care

The impetus towards basing practice and policy decisions moreexplicitly on sound research requires tools to facilitate thesystematic appraisal of the quality of research encompassinga diverse range of methods and designs. Five exemplar toolswere developed and assessed in terms of their usefulness inselecting studies for inclusion in a systematic review. Thewidely used ‘hierarchy of evidence’ was adaptedand used to appraise internal validity. Four tools were thendeveloped to appraise the external validity dimensions of generalizability(two scales) and methods of data collection (two scales). Methodsof combining the scores generated by each tool were explored.Qualitative and quantitative studies were appraised, not separatedinto two spheres but by using complementary tools developedto appraise different aspects of rigour. There was a high levelof agreement between researchers in applying the tools to twenty-twostudies on decision making by professionals about the long-termcare of older people. The scales for internal validity and generalizabilitydiscriminated between the qualities of studies appropriately.The two tools to appraise data collection gave diverse results.Excluding studies that scored in the lowest category on anyscale appeared to be the scoring system that was most justifiable.This approach is presented to stimulate debate about the practicalapplication of the evidence-based initiative to social workand social care. This study may assist in developing clearerdefinitions and common language about appraising rigour thatshould further the process of selecting robust research forsynthesis to inform practice and policy decisions.

Health Policy and the Politics of Evidence

National decisions on the drugs, treatments and medical devices that should be funded through public expenditure are a fundamental element of health policy. But despite a political emphasis upon evidence‐based policy, the results of rigorous clinical trials and statistical modelling techniques rarely speak for themselves. So, does the pre‐eminence traditionally accorded to quantitative data in the medical field underpin policy decisions on a consistent basis? Or are more subtle, less transparent characteristics of context and interaction evident in the shaping of attendant decisions? This article considers these questions by drawing on a study of decision‐making in the National Institute for Health and Clinical Excellence (NICE)—an organization established by the British government in 1999 to decide whether selected health technologies should be made available throughout the National Health Service in England and Wales. In broad terms, the findings point to the primacy of arguments based on quantitatively oriented, experimentally derived data but also to a discursive hegemony of clinicians and health economists in mediating, including or debarring more qualitative, experientially based evidence. A more complex, dynamic understanding of policy governance in the field of health technology appraisal—founded on a discursive appropriation of the idea of the “common good”—goes some way to explaining the persistence of this hegemony despite an avowedly inclusive, plural approach to decision‐making.
