Covid-19 in Central America: Firm resilience and policy responses on employment

This paper examines how government support interacts with firm-level resilience capabilities in the reduction of layoffs among formal firms in Central America. Our analysis suggests that government support measures play a role in reducing the probability of layoffs among firms with only dynamic resilience capabilities (i.e., those that are developed after the pandemic onset). The effect of government support is not statistically different from the effect of static resilience capabilities alone (i.e., those that were present before the pandemic); thus, in firms with such capabilities, the effect of government support will be marginal. These results hold across sectors - exhibiting a marginally higher treatment effect in service sectors. Our results do not imply that Covid-19 supportive measures are to be disregarded, but instead raise the question of how government support policies could improve the allocation of support among firms in times of crises. Moreover, it underlines the necessity of policies that enhance resilience more broadly – a task that hints at structural issues and requires continuous government support in lieu of ad-hoc measures.     

Reflections on grounding firm innovation and viability

Entrepreneurial activity unfolds in a dynamic environment that challenges business viability. We utilize grounded theory as a novel type of reflection to explain and interpret whether and how innovation can afford survival benefits to firms. The premise is the application of a methodological approach with reflexive properties to advance scientific rigor in “reflections.” The idea underlying our reflection was to use innovation as the point of departure, review the literature, conceptualize ideas, and finally link the concepts that emerged as components of a framework. Our view of the firm resembles a viable entity that changes, constantly striving to meet and balance internal potentials and external complexities, while innovation per se involves change that is made possible by entrepreneurship. We bring together our personal and professional backgrounds and implement the European scholarly tradition on innovation and Viable Systems approach to scrutinize innovation’s interactions and relations. We linked boundary conditions, opportunities, and complementary assets to innovation. Effectively, our analysis conceptualizes innovation as autopoiesis in entrepreneurship and demonstrates its central role as the vehicle to exploit changes that ensure firm viability.     

Do greater amounts of FDI cause higher pollution levels? Evidence from OECD countries

Using an ARDL model for a panel of 15 OECD countries, this work analyses the impact that FDI, both jointly and by sector, has on CO₂ emissions. The findings reveal that these countries are yielding to the pressure on the trade sector. Unexpectedly, gross fixed capital formation shrink pollution, excluding in the mining sector. With findings supporting the Pollution Haven Hypothesis, policymakers must pay attention to FDI inflows, ensuring that FDI place high importance on the transfer of green technologies to improve the efficiency. These goals could be achieved through an increase in the stringency of environmental laws within the host countries, especially the ones related to FDI.

Replication: Cheating,loss aversion,and moral attitudes in Vietnam

We use the coin-flip paradigm and a short survey about moral attitudes under three conditions to answer three questions: (i) Do people cheat more when financial incentives are present in comparison with no incentives? (ii) Do they find it more difficult to maintain their ethical standards when they have been given a small amount of money? and (iii) Do moral attitudes predict cheating behavior? Using a sample of Vietnamese college students, we discover that a financial incentive does not matter until people feel that they are facing a loss. In addition, we do not find any evidence that moral attitudes could predict the unethical behavior in our sample. Our findings shed further light on cheating behaviors and loss aversion through an experimental investigation.     

属性集容量确定的夹挤式测度模式及其推算模型

迄今，为解决多属性偏好关联决策属性集容量判断指数复杂性难题所提出的λ模糊测度模式与k-可加模糊测度模式，以及建构在它们之上的属性集容量确定的推算模型，尚存在着适用性差的技术不足。为此，以平衡容量判断的可操作性和容量推算的准确性为视角，提出了一种新容量测度模式，即关于容量判断与推算的夹挤式测度模式，并在此基础上通过引入决策者较易判断给出的容量序信息构建了相应的容量推算模型。基于数值模拟的对比分析表明：新模式不仅在应用可行性上高于k-可加模糊测度模式，而且从容量推算的准确性上看也明显优于λ模糊测度模式和k-可加模糊测度模式，因而对实际决策具有更强的适用性。     

怀疑主义与认知价值

当代知识论越来越重视认知价值的研究，但从认知价值角度去重新思考传统怀疑主义问题的研究却很少。历史上的怀疑主义者既认为我们无法拥有任何知识，又主张我们应该悬置判断。因此，他们不仅预设了一个高的知识标准，而且预设了一个价值标准：任何达不到知识标准的认知状态都是没有认知价值的。但这个价值标准是错误的，所以我们即使无法达到怀疑主义者所设定的知识标准，也不必悬置判断。假设怀疑主义者认为我们无法拥有任何知识，同时认可“有些达不到知识标准的认知状态也有认知价值”，那么怀疑主义就没有很大的威胁性，因为即使我们无法获取知识，也可以获得具有认知价值的东西，取得认知进步。此外，摩尔主义、语境主义、溯因主义这几种对怀疑主义的主要回应是否成功，最终都依赖于对认知价值的讨论。     

Public relations and artificial intelligence: It’s not (just) about robots

Organizations of all kinds, as well as their in-house or agency public relations teams, increasingly co-opt Artificial Intelligence (AI) to enhance their capabilities. This paper examines a relatively new topic that has received little scholarly attention: the growing relationship between AI and public relations. It outlines several key roles that AI may play in future, based on trends in other industries, and considers the implications for public relations practitioners, their clients and employers. It therefore launches a dialogue about the diversity and extent of AI’s uses in public relations practice. The paper argues that, to date, commentators have placed too much emphasis on AI’s potential for task automation; AI’s broader technological, economic and societal implications for public relations warrant greater critical attention. This does not imply that practitioners need become expert technologists; rather, they should develop a sufficient understanding of AI’s present and potential uses to be able to offer informed counsel.     

Impact of support networks for breastfeeding: A multicentre study

Background

The rates of breastfeeding worldwide are slowly improving since 1996. Europe is still trailing behind the global breastfeeding incidence and prevalence rates. Thus, breastfeeding promotion, protection, prolongation and support have become an important challenge as breastfeeding sharply decreases in the first six months of life.
