This study examines how contextual, structural and functioning characteristics of industrial clusters influence their effectiveness. We develop a conceptual framework that identifies potential influencing factors, validate the factors statistically, and estimate the factors’ impact on cluster effectiveness. Our results show that among the important determinants of cluster effectiveness are long-term planning security and procedural trust among the cooperating firms (contextual conditions), formalized rules and sustainable structures (structural elements), and clear goals and tasks (functioning characteristics). However, the results also reveal that some determinants assessed as important in the literature do not seem to have a positive impact on effectiveness. Our results not only modify general assumptions in cluster research concerning the drivers of cluster effectiveness, but also assist firms and policy-makers in conceptualizing successful new clusters. 相似文献

We extend the entrepreneurship literature to include positive psychological capital — an individual or organization's level of psychological resources consisting of hope, optimism, resilience, and confidence — as a salient signal in crowdfunding. We draw from the costless signaling literature to argue that positive psychological capital language usage enhances crowdfunding performance. We examine 1726 crowdfunding campaigns from Kickstarter, finding that entrepreneurs conveying positive psychological capital experience superior fundraising performance. Human capital moderates this relationship while social capital does not, suggesting that costly signals may, at times, enhance the influence of costless signals. Post hoc analyses suggest findings generalize across crowdfunding types, but not to IPOs. 相似文献

Hunger games: or how the Allied blockade in the First World War deprived German children of nutrition,and Allied food aid subsequently saved them

At the onset of the First World War, Germany was subject to a shipping embargo by the Allied forces. Ostensibly military in nature, the blockade prevented not only armaments but also food and fertilizers from entering Germany. The impact of that blockade on civilian populations has been debated ever since. Germans protested that the Allies had wielded hunger as a weapon against women and children with devastating results, a claim that was hotly denied by the Allies. The impact of what the Germans termed the Hungerblockade on childhood nutrition can now be assessed using a newly discovered dataset based on heights and weights of nearly 600,000 German schoolchildren measured between 1914 and 1924. Statistical analysis reveals a grim truth: German children suffered severe malnutrition due to the blockade. Social class impacted risk of deprivation, with working‐class children suffering the most. Surprisingly, they were the quickest to recover after the war. Their rescue was fuelled by massive food aid organized by the former enemies of Germany, and delivered cooperatively with both government and civil society. The ability of former belligerents to work together after an exceptionally bitter war to feed impoverished children may hold hope for the future. 相似文献

Established environmental policy theory is based on the assumption of homo economicus. This means that people are seen as fully rational and acting in a self-regarding manner. In line with this, economics emphasizes efficient policy solutions and the associated advantages of price incentives. Behavioral economics offers alternative, more realistic views on individual behavior. In this paper we investigate opportunities to integrate bounded rationality and other-regarding preferences into environmental policy theory to arrive at recommendations for more effective policies. For this purpose, we will address decisions made under risk and uncertainty, intertemporal choice, decision heuristics, other-regarding preferences, heterogeneity, evolutionary selection of behaviors, and the role of happiness. Three aspects of environmental policy are considered in detail, namely sustainable consumption, environmental valuation and policy design. We pay special attention to the role of non-pecuniary, informative instruments and illustrate the implications for climate policy. 相似文献

Routine vaccination against human papillomavirus (HPV), the main cause of cervical cancer, is recommended for 11-12 year old girls, yet vaccine uptake is low. This study evaluates a social marketing campaign initiated by 13 North Carolina counties to raise awareness among parents and reduce barriers to accessing the vaccine in a primarily rural area. The 3-month campaign targeted mothers of girls ages 11-12 and healthcare practices serving pre-teen girls in four counties. Principles of social marketing were: product (recommended vaccine against HPV), price (cost, perception of safety and efficacy, and access), promotion (posters, brochures, website, news releases, doctor's recommendation), and place (doctors' offices, retail outlets). We analyzed (1) website traffic, hotline calls, and media placement; (2) cross-sectional surveys of mothers and providers; and (3) HPV immunization rates in intervention versus non-intervention counties. Of respondent mothers (n=225), 82% heard or saw campaign messages or materials. Of respondent providers (n=35), 94% used campaign brochures regularly or occasionally in conversations with parents. HPV vaccination rates within six months of campaign launch were 2% higher for 9-13 year old girls in two of the four intervention counties compared to 96 non-intervention counties. This evaluation supports campaign use in other primarily rural and underserved areas. 相似文献

Conversion of farmland to non-agricultural uses presents a challenge to future food production and ecosystem services in US and Canada. Expansions of housing, transportation, industry, retail sales, schools and other developments are driving land out of farming. In the US there is annual conversion of 500,000 ha away from food and fibre production systems. Coupled with 1% annual population increase, this will reduce today's 0.6 ha per person to 0.3 ha by 2050. Canada has more land and smaller population, but farmland losses are occurring in fertile areas near coasts and in level valleys where highest quality land is located. Current rates of increase in agricultural productivity will not compensate for this land loss. Compared to US, there are more specific tools and legislation at the provincial level in Canada that provide opportunities for controlling sprawl. Important in both countries is general lack of awareness and concern about loss of productive farmland, a situation that could be improved through education. Stimulating collective understanding of this growing problem and providing viable solutions could provide the basis for national policy strategies to promote and assure sustainable food systems for the future and enhance the capacity to maintain vital ecosystem services. 相似文献

Sport sponsorship is an important marketing communication tool, and stakes in sponsorship deals are high. Therefore, sponsors strive to ensure that their investments are effective and protected from competitors—that is, ambusher marketers’ attacks. Still, little is known about how ambush marketing affects sponsor identification and misidentification of ambushers as sponsors. This study investigates levels of sponsor and ambusher identification in three experimental settings, controlling for the presence/absence of an ambusher, communication modality, and response formats. A field study in the context of a large sports event demonstrates the external validity of the findings. The results provide evidence of a nondestructive interference of ambush marketing, indicating that ambush marketing does not necessarily harm sponsor identification. Misidentification of nonsponsors as sponsors occurs because of the indirect link established between the event and the company through ambush marketing, but not as a consequence of other communication activities by a competitor with no link to the event. Finally, a combined sponsor–ambusher perspective indicates that sponsors do not necessarily have a consistent “official sponsor” advantage over ambushers. Findings are discussed with emphasis on implications for sponsors, ambushers, and marketing researchers. 相似文献

College and university faculty in Family and Consumer Sciences (FCS) programs are becoming more involved in online course design and instruction. The purpose of this article is twofold. First, examples of several existing FCS online programs are presented. Many online programs are being offered in the United States, and several are offered in an international setting (e.g. British Columbia, Saudi Arabia, and Thailand). Second, four models of education that FCS instructors can draw upon for teaching online are presented. The models are positivism, constructivism, the community of inquiry approach, and experiential learning. Positivism should be utilized when the goal is to teach specific and basic knowledge, which is usually contained in lectures and readings. Other models are more appropriate when the goal is to cultivate students' higher level thinking through dynamic learning processes. Constructivism is based on the assumption that learners are active creators of knowledge and meaning. The community of inquiry approach highlights the importance of building relationships for learning. The experiential learning model involves direct participation in realistic contexts and should be followed with reflection on the general principles of the learning situation. Online teaching strategies, examples, and limitations are presented for each model. 相似文献
