This paper starts from the premise that crisis is a perception and that one of the best ways to conquer a crisis is not to allow it to develop in the first place. By detecting or perceiving a crisis before other stakeholders do, an organisation can prevent or mitigate a crisis. Few studies have considered the question of whether organisations put the right people in the right places to be able to see a crisis coming. Within an organisation, managers are usually well placed to take decisions to initiate crisis communication, but they seem to be reluctant to do so or may not wish to see an impending crisis. Communication professionals should have a better perception of a crisis, but they rarely find themselves in a position to have a substantial impact on the management decision to communicate during a crisis. In this paper, we study crisis perception by individuals in a large governmental organisation during various stages of an unfolding crisis and compared perception scores to individual profiles based on study background, professional situation and crisis experience. This study involves a large-scale scenario-driven survey with ‘crisis perception’ as the main dependent variable. The results of this specific case indicate that an academic communication degree, a high hierarchical position in the organisation and crisis experience are positively related to an augmented perception of an impending organisational crisis.  相似文献

This article analyses the socio‐economic determinants of public preferences towards public spending and parental fees for childcare and how they are conditioned by institutional contexts. Previous studies of childcare policy preferences have focused on attitudes regarding the provision of care. However, when it comes to questions of financing, we know astonishingly little about how supportive individuals actually are of expanding pre‐school early childhood education and care, and how support varies across different socio‐economic groups in society. This is an important research gap because childcare provision and how it is financed have redistributive implications, which vary depending on the institutional design of childcare policy. Using novel and unique survey data on childcare preferences from eight European countries, we argue and show that preferences towards expanding childcare are more contested than it is often assumed. The institutional structure of childcare shapes how income matters for preferences towards how much should be spent and how provision should be financed. Where access to childcare is socially stratified, the poor and the rich develop different preferences towards either increasing public spending or reducing parental fees in order to improve their access to childcare. The findings in this article suggest that expanding childcare in systems characterised by unequal access can be politically contested due to diverging policy priorities of individuals from different social backgrounds.  相似文献

We model a dynamic, competitive market, where in every period, risk‐neutral traders trade a one‐period bond against an infinitely lived asset, with limited short‐selling of the long‐term asset. Traders lack structural knowledge and use different “incomplete theories,” all of which give statistically correct beliefs about next period's market price of the long‐term asset. The more theories there are in the market, the higher is the equilibrium price of the long‐term asset. Investors with more complete theories do not necessarily earn higher returns than those with less complete ones, who can earn above the risk‐free rate. We provide two necessary conditions for a trader to earn above the risk‐free rate.  相似文献

To learn about the progression of a complex disease, it is necessary to understand the physiology and function of many genes operating together in distinct interactions as a system. In order to significantly advance our understanding of the function of a system, we need to learn the causal relationships among its modeled genes. To this end, it is desirable to compare experiments of the system under complete interventions of some genes, e.g., knock-out of some genes, with experiments of the system without interventions. However, it is expensive and difficult (if not impossible) to conduct wet lab experiments of complete interventions of genes in animal models, e.g., a mouse model. Thus, it will be helpful if we can discover promising causal relationships among genes with observational data alone in order to identify promising genes to perturb in the system that can later be verified in wet laboratories. While causal Bayesian networks have been actively used in discovering gene pathways, most of the algorithms that discover pairwise causal relationships from observational data alone identify only a small number of significant pairwise causal relationships, even with a large dataset. In this article, we introduce new causal discovery algorithms—the Equivalence Local Implicit latent variable scoring Method (EquLIM) and EquLIM with Markov chain Monte Carlo search algorithm (EquLIM-MCMC)—that identify promising causal relationships even with a small observational dataset.  相似文献

Family businesses are publicly believed to be highly innovative and to be the “Hidden Champions” of the German industry. In recent times scholars have begun to examine this thesis and have come to starkly opposing results. On the one hand family businesses are attested to have a special ?entrepreneurial “spirit” which makes them highly innovative. On the other hand the lack of separation of ownership and control and insufficient diversification of family-investors are said to lead to less innovation activity. In this study we investigate the innovation activity of 384 German manufacturing firms differing in legal structure, size, age, industry, and—most importantly—in the degree of family ownership, family management and family control. The results of our analysis reveals differentiated results. Fundamentally, family ownership and family management are detrimental to firm innovation, at the same time family control has a positive impact on innovation activities. Our Results point to the fact that owner-managed businesses tend to innovate less due to risk aversion while a focus on controlling instead of managing a corporation by the owning family lead to an increase in innovations.  相似文献

The present study evaluates the interplay between the effects of host countries' characteristics and self-selection patterns of immigrants from a highly developed country on their economic assimilation in other developed countries. The focus is on immigrants originated from Germany during 1990–2000 who migrated to Sweden and the US. The results show that almost all German immigrants reached full earnings assimilation with natives of similar observed attributes, and that the assimilation of highly educated Germans was better than that of the less educated. It was also found that the skilled immigrants were compensated for their human capital acquired in Germany. Finally, the better assimilation of German immigrants, especially the highly educated, took place in the US. This finding was probably the result of an interaction between the Germans’ pattern of self-selection and the US context of reception.  相似文献

After the British government announced in March 1996 that a novel fatal human disease (now called variant Creutzfeldt–Jakob disease) had emerged and was almost certainly caused by consuming BSE–contaminated food, national and international authorities have been struggling to deal with the consequences of a serious loss of public confidence in the safety of foods and in food safety policy–making institutions. One of the main ways in which governments and officials have responded to those challenges has been by initiating a broad range of structural and procedural reforms to the ways in which public policies are decided, legitimated and communicated. This paper outlines some of the more important respects in which national and international authorities have changed the ways in which they assess and manage the risks to human consumers of food–borne hazards. The focus is on developments in the UK, the EU and, at the global level, the Codex Alimentarius Commission; the period covered runs from the late 1960s until summer 2002. The discussion focuses on the case for separating the responsibilities for regulating and sponsoring the agricultural and food industries, for conducting risk appraisals and decision–making in open and democratically accountable ways and for drawing on experts representing a wide range of interests and expertise rather than on a narrow industry–based group. The paper concludes by indicating some key structural and procedural conditions for effectively differentiating the scientific from the political aspects of risk appraisal and decision–making, and then for coupling them together in ways that would provide both scientific and democratic legitimacy.  相似文献

We review the literature on determinants of ethnic/national self-identities and self-esteem as a prelude to examining these outcomes among a large, statistically representative sample of second generation adolescents in Madrid and Barcelona. While these psycho-social outcomes are malleable, they still represent important dimensions of immigrant adaptation and can have significant consequences both for individual mobility and collective mobilizations. Current theories are largely based on data from the USA and other Anglophone countries. The availability of a new large Spanish survey allows us to test those theories in an entirely different socio-cultural context. The analysis concludes with a structural equations model that summarizes key determinants of national identities and self-esteem among children of immigrants in Spain. Theoretical and practical implications of these findings are discussed.  相似文献
