Reassessing the risk conditions for political instability in the light of the Arab Spring

In today’s globalized world, multinational firms contend with a diverse set of risk factors in their worldwide operations. The recent regime changes in northern African countries, also called the Arab Spring, have highlighted that political instability is one of these factors. As researchers and existing indices of political instability largely failed to predict those developments, firms had not incorporated them into their risk calculations and hence incurred losses while having to adapt their operations. This paper examines the conditions that contributed to the recent instability in North Africa using Tunisia and Egypt as case studies. It evaluates the extent to which existing measures of political instability incorporate those conditions. The analysis reveals that the main conditions contributing to the political turmoil can be seen in socio-economic factors, namely inequality, poverty, youth unemployment, a growing youth population, and especially in the case of Egypt an independent military. These findings reveal gaps in current measures of political instability, whose dominant focus is on factors describing violence and changes in the political system while neglecting the influence of a country’s socio-economic environment.     

Wholly owned foreign subsidiary relation-based strategies in volatile environments

Drawing from dynamic capability, institutional, nonmarket strategy, and social-network literatures, we detail wholly owned subsidiary (WOFSs) relation-based strategies (RBSs). We explain how deploying RBSs with key nonmarket and market actors will create competitive advantages for WOFSs operating in volatile emerging market environments. We posit that dynamic capabilities will drive the deployment of RBSs by WOFSs, and argue that the positive relationship between dynamic capabilities and RBS deployment will strengthen as perceived institutional uncertainty increases. We further suggest that the greater the strength and frequency of RBS deployment, the more likely that a WOFS will establish a combination of nonmarket-based and market-based embedded assets. Also, our theory proposes that greater integration of nonmarket-based and market-based assets will enhance WOFS financial performance outcomes. Implications for future research are discussed.     

The impact of relative residence times on the distribution of heavy drinkers in highly distinct environments

Alcohol consumption is a function of social dynamics, environmental contexts, individuals' preferences and family history. Empirical surveys have focused primarily on identification of risk factors for high-level drinking but have done little to clarify the underlying mechanisms at work. Also, there have been few attempts to apply nonlinear dynamics to the study of these mechanisms and processes at the population level. A simple framework where drinking is modeled as a socially contagious process in low- and high-risk connected environments is introduced. Individuals are classified as light, moderate (assumed mobile), and heavy drinkers. Moderate drinkers provide the link between both environments, that is, they are assumed to be the only individuals drinking in both settings. The focus here is on the effect of moderate drinkers, measured by the proportion of their time spent in “low-” versus “high-” risk drinking environments, on the distribution of drinkers.A simple model within our contact framework predicts that if the relative residence times of moderate drinkers are distributed randomly between low- and high-risk environments then the proportion of heavy drinkers is likely to be higher than expected. However, the full story even in a highly simplified setting is not so simple because “strong” local social mixing tends to increase high-risk drinking on its own. High levels of social interaction between light and moderate drinkers in low-risk environments can diminish the importance of the distribution of relative drinking times on the prevalence of heavy drinking.     

制度环境、政治联系与民营企业债务期限结构

以2007-2009年在沪深上市的民营上市公司为研究样本,对制度环境、政治联系如何影响企业债务期限结构进行分析。研究发现:在法律环境较差、地区金融发展水平落后、政府干预较强的地区,民营企业长期债务的比重越大。在考虑企业家政治背景后发现,政治联系有助于民营企业获得更多的长期债务,特别是在制度环境较差地区,政治联系的这种效应更显著。这表明,政治联系是制度环境不完善条件下的一种替代机制。     

Environmental factors of food literacy in Australian high schools: views of home economics teachers

This study set out to examine environmental factors impacting on the food literacy of adolescents. It utilized data from a nation‐wide survey of home economics teachers regarding their experience of food literacy education in Australian high schools. Content analysis and the ANGELO framework were applied to analyse free‐text comments from 78 of the respondents that were collected as part of a more extensive data set. The analysis of environmental factors revealed three enablers and ten barriers that could influence food literacy education delivered by high schools in Australia. High schools are well positioned to improve adolescents’ food literacy through a comprehensive, hands‐on approach in home economics. However, many environmental barriers were reported that could influence food literacy education in Australian high schools such as: lack of teaching materials and facilities, and human resources; the perceived inadequacy of the Australian school curriculum; non‐supportive school canteens; and negative role modelling. This study points to the need to eliminate or reduce these environmental barriers impacting on the capacity for effective food literacy education in high schools to help adolescents increase their food literacy and thereby support them in making informed food choices.     

China’s telecommunications evolution,institutions, and policy issues on the eve of 5G: A two-decade retrospect and prospect

Over the past two decades, China’s telecommunications industry has witnessed drastic market reform, steadfast institutionalization, and volatile technological changes, which have driven exponential industry expansion. This paper offers an updated longitudinal and comprehensive review on this reform process on the eve of 5G (the fifth generation mobile communications networks). First, the paper segments the two-decade reform crusade into discernible phases, each of which is embedded with different policy drives. These reform phases are then pattern-matched against the subtleties of the overall institutional, technological, and market backdrop. A series of policy issues are identified through a systematic examination of industry phenomena over the reform course. Finally, the status of research is assessed regarding China’s telecom industry and reform, based on which, knowledge gaps are identified and future research agenda suggested. Conclusions are made regarding future reform and research imperatives. The paper advances the understanding of China’s telecom reform, development, and the underlying policy issues. It updates and expands previous works on similar topics. Overall, this study provides important theoretical, managerial, and policy implications.

The influence of colour on visual search times in cluttered environments

Fifty subjects participated in a series of visual search tasks where the aim was to explore the influence of colour on visual search times for targets situated in a series of cluttered distractor fields. The results supported previous findings regarding the effect of colour and showed that, even in cluttered environments, certain hues helped in the reduction of search times. The findings also indicated that there were interaction effects between the colour and positioning of the targets in the distractor fields.     

Statistical Thinking in Computer-Based Learning Environments

The theme of technology is particularly important for statistics education because of the role of technology in changing views of statistical knowledge, pedagogy and learning. The interactive multimedia technology of today allows for the creation of powerful learning environments where the focus is on the process that produced the data and its associated variation and the statistical thinking required to solve the problem. However, despite this optimistic view, students' self‐regulation and intrinsic motivation seem to be key concepts for learning in complex interactive computer‐based learning environments. We conclude with observations of teachers and students working with applets. More of these evaluations should be published and/or made available to the statistical community so that both positive and negative teaching experiences can be shared.     

Estimating choice models in data-sparse environments: Taking advantage of perceived similarity

Research suggests that choice models conditioned on correctly identified consideration sets outperform choice models conditioned on the awareness set (Hauser, 1978; Roberts and Lattin, 1991). However, in data-sparse environments, where purchase history information is not available or not relevant, choice models conditioned on the consideration set often yield nonunique or nonsignificant solutions. In these environments, we propose the use of similarity information to improve the performance of choice models. Support for this position is found in an empirical application involving automobiles.
