Academic Entrepreneurship: Time for a Rethink?

Academic entrepreneurship, which refers to efforts undertaken by universities to promote commercialization on campus and in surrounding regions of the university, has changed dramatically in recent years. Two key consequences of this change are that more stakeholders have become involved in academic entrepreneurship and that universities have become more ‘strategic’ in their approach to this activity. The authors assert that the time is ripe to rethink academic entrepreneurship. Specifically, theoretical and empirical research on academic entrepreneurship needs to take account of these changes, so as to improve the rigour and relevance of future studies on this topic. We outline such a framework and provide examples of key research questions that need to be addressed to broaden understanding of academic entrepreneurship.     

Countering Overseas Power in Global Value Chains: Information Asymmetries and Subcontracting in the Plastics Industry

Resource Dependency Theory (RDT) and Global Value Chain (GVC) analysis have been deployed in the strategic and international management literatures to address questions of power in dyadic relationships and global production networks, respectively. This paper integrates the two theoretical approaches in order to expand RDT, using insights from Hirschman's exit/voice model to show the options available to some firms but not others. Using the relationship between buyers and contract manufacturers from GVC analysis, we find a correlation between firm size and choice of strategic action in response to contract manufacturers' dependence on buyers. Large firms follow an acquiescence strategy while small manufacturers follow an avoidance strategy, able to use both exit and voice strategies. Enabled by scale or control over information, both of these approaches successfully reduce uncertainty and provide a source of sustained competitive advantage. Using a study of the production chain in consumer plastics manufacturing in China, we show how dependent firms respond to GVC induced pressure. We find that based on the size of the contract manufacturer, the range of strategic responses to power is constrained by the nature of the dependency in global value chains. This opens important insights into the role that structural characteristics of organizations (like size) play in determining strategic freedom.     

Hypothesis Tests for Neyman's Bias in Case–Control Studies

Survival bias is a long recognized problem in case–control studies, and many varieties of bias can come under this umbrella term. We focus on one of them, termed Neyman's bias or ‘prevalence–incidence bias’. It occurs in case–control studies when exposure affects both disease and disease-induced mortality, and we give a formula for the observed, biased odds ratio under such conditions. We compare our result with previous investigations into this phenomenon and consider models under which this bias may or may not be important. Finally, we propose three hypothesis tests to identify when Neyman's bias may be present in case–control studies. We apply these tests to three data sets, one of stroke mortality, another of brain tumors, and the last of atrial fibrillation, and find some evidence of Neyman's bias in the former two cases, but not the last case.     

Social inclusion through employment: the marketisation of employment support for people with learning disabilities in the United Kingdom

Employment for people with learning difficulties is considered key to their social inclusion. This contradicts the perceived un-employability of people with learning difficulties that has been part of their social identities throughout their history hitherto. The national rate of employment for people with learning difficulties remains extremely low and has barely changed in the 20?years between 1990 and 2010. This paper investigates links between learning disabilities and employment, drawing on interview-based research. It analyses the quality of experience of the minority in employment to consider whether employment can serve the inclusive purpose expected of it.     

Reviewing the Reviews: Discussions of Race by Film Reviewers

Color-blind racism has transformed how race scholars understand race relations in contemporary society. Previous researchers mainly utilized this theory to identify frames of color-blind racism in various social settings and interactions. What has received less attention, however, is how frames of color-blind racism are produced within material conditions in which social interactions and relations occur. In this study we use film reviews to exemplify how color-blind racism is produced in a specific materialist context—film reviews. Film reviews garner discussion among scholars for their impact on the box office revenues of films. Less attention is given to the content of these reviews and, particularly, how their writers address issues of race. This study provides a qualitative content analysis of film reviewer’s discussions of race in their reviews of twenty-first-century films featuring black protagonists to illuminate some ways in which mainstream and niche media outlets discuss race. Results suggest that the source of the reviews influences how race is considered and communicated among film reviewers. Mainstream reviewers differ widely from niche reviewers in both content and delivery in their discussions of race.     

Perception of Climate Risk among Rural Farmers in Vietnam: Consistency within Households and with the Empirical Record

Rural farmers in Vietnamese communes perceive climate risk and potential impacts on livelihood within a complex context that may influence individual and household decisions. In a primary survey of 1,145 residents of the Thach Ha district of Ha Tinh province, we gathered data regarding perception about stability in climate, potential risks to livelihood, demographic characteristics, orientation toward risk, and interest in expanding economic activity. Temporal analysis of meteorological and economic indicator data forms an empirical basis for comparison with human perception. We ask the basic question: Are rural farmers’ perceptions of climate consistent with the historical record and reproducible within households? We find that respondents do perceive climate anomalies, with some anchoring on recent extreme events as revealed by climate observational data, and further that spouses disproportionately share perceptions relative to randomly simulated pairings. To put climate‐related risk perception in a larger context, we examine patterns across a range of risks to livelihood faced by farmers (livestock disease, pests, markets, health), using dimension reduction techniques. We find that our respondents distinguish among potential causes of low economic productivity, with substantial emphasis on climate‐related impacts. They do not express uniform concern across risks, but rather average patterns reveal common modes and distinguish climate concern. Still, among those expressing concern about climate‐related risks to livelihood we do not find an association with expressed intention to pursue changes in economic activity as a risk management response.     

The Value of Information in Decision‐Analytic Modeling for Malaria Vector Control in East Africa

Decision analysis tools and mathematical modeling are increasingly emphasized in malaria control programs worldwide to improve resource allocation and address ongoing challenges with sustainability. However, such tools require substantial scientific evidence, which is costly to acquire. The value of information (VOI) has been proposed as a metric for gauging the value of reduced model uncertainty. We apply this concept to an evidenced‐based Malaria Decision Analysis Support Tool (MDAST) designed for application in East Africa. In developing MDAST, substantial gaps in the scientific evidence base were identified regarding insecticide resistance in malaria vector control and the effectiveness of alternative mosquito control approaches, including larviciding. We identify four entomological parameters in the model (two for insecticide resistance and two for larviciding) that involve high levels of uncertainty and to which outputs in MDAST are sensitive. We estimate and compare a VOI for combinations of these parameters in evaluating three policy alternatives relative to a status quo policy. We find having perfect information on the uncertain parameters could improve program net benefits by up to 5–21%, with the highest VOI associated with jointly eliminating uncertainty about reproductive speed of malaria‐transmitting mosquitoes and initial efficacy of larviciding at reducing the emergence of new adult mosquitoes. Future research on parameter uncertainty in decision analysis of malaria control policy should investigate the VOI with respect to other aspects of malaria transmission (such as antimalarial resistance), the costs of reducing uncertainty in these parameters, and the extent to which imperfect information about these parameters can improve payoffs.     

Inequality and the Self: Exploring Connections from an Interactionist Perspective

Symbolic interactionism provides a major contribution to understanding inequality by illuminating the various manifestations and contexts of inequality at the micro, everyday level of social life. Drawing on a spectrum of symbolic interactionist theory and research, we examine the range of symbolic and interactional manifestations of social inequality, the consequences of being the object of patterned interactional affronts, and the strategies people use to negotiate interactional stigmatization in everyday life. We argue that symbolic interaction's unique contribution to understanding inequality results from two of the perspective's central features. First, symbolic interactionism emphasizes the necessity of investigating social life in situated social interaction. Second, it highlights social actors' capacities to interpret and construct lines of action rather than respond directly to the stimuli they encounter. Symbolic interactionist research and theory thus contribute to a more complex understanding of social stratification than that provided by perspectives focused exclusively on macroscopic structural factors.
