The primary contributions of smallholders during the communist and early postcommunist periods have been food production and labour for large farms. Those conditions are changing, however, as modern farms require less labour and food supply may be imported. For most smallholders in Central and Eastern European and former Soviet Union countries, the postcommunist neoliberal environment has not brought significant improvement, and strong arguments can be made that land grabbing, social and economic exclusion, and rural poverty are worse than regime bias during the communist period. Cooperatives, which have empowered smallholders in other parts of the world, have not been as well developed in postcommunist nations. 相似文献

Genetically engineered (GE) crops are subject to regulatory oversight to ensure their safety for humans and the environment. Their approval in the European Union (EU) starts with an application in a given Member State followed by a scientific risk assessment, and ends with a political decision‐making step (risk management). In the United States (US) approval begins with a scientific (field trial) step and ends with a ‘bureaucratic’ decision‐making step. We investigate trends for the time taken for these steps and the overall time taken for approving GE crops in the US and the EU. Our results show that from 1996–2015 the overall time trend for approval in the EU decreased and then flattened off, with an overall mean completion‐time of 1,763 days. In the US in 1998 there was a break in the trend of the overall approval time. Initially, from 1988 until 1997 the trend decreased with a mean approval time of 1,321 days; from 1998–2015, the trend almost stagnated with a mean approval time of 2,467 days. 相似文献

Indian firms are challenged by the latecomer disadvantages faced by emerging‐market multinational enterprises (EMNEs) in general. These challenges notwithstanding, Indian firms are doing cross‐border acquisitions (CBAs) in developed regions. Analyzing firm‐level secondary data of two Indian MNEs—namely, Motherson Sumi Systems Limited and Rain Industries Limited—that show significant developed region–based revenues and assets, we link extant and emerging theoretical perspectives on EMNEs’ internationalization with the observed firm motives and behaviors of our case firms. We propose a framework of multiple contextual settings to understand the context‐driven internationalization of the case firms. Finally, our article offers a set of propositions emphasizing firm‐level entrepreneurial orientation and international orientation, when EMNEs internationalize via CBAs in developed regions. © 2017 Wiley Periodicals, Inc. 相似文献

This paper uses a natural experiment—the Super Bowl—to study the causal effect of advertising on demand for movies. Identification of the causal effect rests on two points: 1) Super Bowl ads are purchased before advertisers know which teams will play; 2) home cities of the teams that are playing will have proportionally more viewers than viewers in other cities. We find that the movies in our sample experience on average incremental opening weekend ticket sales of about $8.4 million from a $3 million Super Bowl advertisement. 相似文献

Despite the benefits of walking as a means of travelling, walking can be quite hazardous. Pedestrian-vehicle crashes remain a major concern in Ghana as they account for the highest percentage of fatalities. The objective of this study is to determine the effect of both natural and built environmental features on pedestrian-vehicle crash severity in Ghana. The study is based on an extensive pedestrian-vehicle crash dataset extracted from the National Road Traffic Accident Database at the Building and Road Research Institute (BRRI) of the Council for Scientific and Industrial Research (CSIR), Ghana. Using a multinomial logit modelling framework, possible determinants of pedestrian-vehicle crash severity were identified. The study found that fatal crashes are likely to occur during unclear weather conditions, on weekends, at night time where there are no lights, on curved and inclined roads, on untarred roads, at mid-blocks and on wider roads. The developed model and its interpretations will make important contributions to road crash analysis and prevention in Ghana with the possibility of extension to other developing countries. These contributing factors could inform policy makers on road design and operational improvements. 相似文献

Food expenditures, influenced by social, demographic, and economic factors, constitute a significant proportion of the typical rural Indian's household income. Based on cross‐sectional household data, this study employs the Quadratic Almost Ideal Demand System to estimate food demand among rural Indian households. Special attention is given to the rural household's two‐stage budgeting in total food expenditure and then to a demand for a specific food item. Conditional and unconditional expenditure and price elasticities for seven food groups are estimated. Results indicate that own‐price elasticities for each group are negative ranging from fairly inelastic to elastic range. Expenditure elasticities indicate that food items are a normal necessity to luxury goods. Additionally, socio‐demographic factors play a significant role in food consumption patterns. Based on our unconditional expenditure elasticities, we also project food demand from rural Indian households for next two decades. Les dépenses alimentaires, qui sont influencées par des facteurs socioéconomiques et démographiques, absorbent une partie considérable du revenu des ménages ruraux typiques en Inde. Dans la présente étude, nous avons utilisé le modèle de demande quasi idéal quadratique pour estimer, à l'aide de données transversales sur les ménages, la demande alimentaire des ménages ruraux en Inde. Nous avons accordé une attention spéciale à la budgétisation en deux étapes des dépenses alimentaires totales et à la demande d'un produit alimentaire particulier du ménage rural. Nous avons estimé les dépenses conditionnelles et inconditionnelles et l’élasticité‐prix de sept groupes alimentaires. Les résultats de notre étude indiquent que l’élasticité‐prix de chaque groupe est négative et qu'elle varie de plutôt inélastique à divers degrés d’élasticité. L’élasticité des dépenses indique que les produits alimentaires varient de nécessités de base à produits de luxe. Les facteurs sociodémographiques jouent également un rôle important dans les habitudes de consommation alimentaire. D'après les élasticités des dépenses établies dans notre étude, nous avons estimé la demande alimentaire des ménages ruraux en Inde pour les deux prochaines décennies. 相似文献

Mixed-race representations have become increasingly evident in marketing communications through the use of celebrity spokespersons like Misty Copeland and Halle Berry. This study explores the sociocultural ramifications of the ways in which marketers represent multiracial identity. Through an interdisciplinary review of pertinent literature, the authors create a theoretical framework for understanding the limitations of visual representations. A temporal model for discerning visual representations of the multiracial identity emerged by combining critical discourse analysis (CDA) techniques to investigate multiracial advertising depictions in eight popular U.S. magazines with interviews of multiracial women and advertising professionals. Findings suggest that marketers use mixed-race representations as cultural currency by mythologizing mixed-race bodies as the new beauty standard and as representing a racial bridge, physically and culturally tailored to ameliorate perceived racial divides. While visual representations in marketing communication have served to legitimatize and normalize mixed-race identity, these images generally ignore mundane consumption practices, obscure the relationships and processes that bring about multiracial bodies, and are devoid of sociopolitical context. The authors offer a framework through which scholars can systematically analyze the sociocultural significance of a wide range of identity coordinates utilized in advertisements and other forms of marketing communication. 相似文献

The present study draws on the concepts of motives and heuristics to thoroughly understand consumers’ sustainable consumption behaviour in the context of personal care products. The mixed-methods approach combines real purchasing data with in-depth qualitative data to generate insights with a high external validity. In the first section of the study, quantitative analysis is applied to actual purchasing behaviour (n = 10,772,477) to identify market trends. Three main groupings, along with specific heuristic cues, are established. In the second step, a qualitative study (n = 21) provides deeper insights into consumers’ motives and decision-making processes. By synthesising the quantitative and qualitative research findings, a segmentation approach is developed. Relevant motives and values, and corresponding specific heuristic cues are identified for each consumer segment. Analysis suggests that consumers are motivated by self-interest and environmental motives, and that they use simple heuristic cues to make quick and satisfying purchasing decisions. Both retailers and manufacturers can leverage these insights to seize the opportunities of the developing market for sustainable personal care products. 相似文献
