Consumer attitudes and acceptance of genetically modified organisms in Korea

Genetically modified organisms (GMOs) were first used to designate micro organisms that had had genes from other species transferred into their genetic material by the then‐new techniques of ‘gene‐splicing.’ Cultivation of GMOs has so far been most widespread in the production of soybeans and maize. The United States holds almost three‐fourths of the total crop area devoted to GMOs. Because many crops have been imported from the US, there is a large possibility for consumers to intake the products of GMOs in Korea. The safety of GMOs is not scientifically settled at this time, however. Additionally, the research regarding the GMOs issue of consumers has rarely been conducted in Korea. This study therefore focused on the consumer attitudes about GMOs and willingness to purchase them. The data were collected from 506 adults living in Seoul, Daegu and Busan, Korea, by means of a self‐administered questionnaire. Frequencies and chi‐square tests were conducted by SPSS. The results of the survey were as follows. First, the consumer concerns about GMOs were high but recognition was low; many respondents answered they did not have exact information about GMOs, although they had heard about them. Second, almost 93% of the respondents desired the labelling of GMOs. Third, the level of acceptance of GMOs was high; two‐thirds of the respondents showed that they were willing to buy GMOs. Finally, many respondents worried about the safety of GMOs in that 73% of the respondents primarily wanted to be informed about safety of GMOs. This study suggests that the consumer education about GMOs should be conducted through mass media and consumer protection organisations.     

Polarization,Inequality, and Growth: The Indian Experience

One issue that has attracted considerable attention recently among scholars interested in inequality and conflict is polarization. We analyze polarization in India over roughly the past three decades using consumption expenditure data. We show that both bipolarization and multidimensional polarization (on several dimensions: rural–urban, state, region) have increased since the 1990s. In the case of bipolarization, this is a reversal from an earlier trend (in the 1980s). Overall, our results suggest that the high growth that India has witnessed since the 1990s has been associated with widening disparities. Comparing polarization and inequality trends, we find similarities, but also some differences; we also show how the study of polarization can provide different insights. Our results therefore underscore the importance of studying polarization as distinct from traditional inequality.     

An investigation into factors impacting financial exclusion at the bottom of the pyramid in South Africa

Financial exclusion has been shown to have negative socio-economic effects on citizens, especially at the bottom of the economic pyramid. South Africa suffers from high levels of financial exclusion, disproportionately at the bottom of the pyramid. This study investigates nine factors identified from the literature as being positively associated with financial exclusion using a logistic regression model. The findings show that the most significant factors associated with being financially excluded at the bottom of the pyramid in South Africa were educational level, primary source of income, age, home language and number of dependents. The study further found that gender, relationship status and home ownership were not associated with being financially excluded. An interesting finding was that living in a rural area as opposed to an urban area was not significantly associated with being excluded. The findings and their implications for expanding financial inclusion at the bottom of the pyramid are discussed.     

Consuming digital technologies and making home

Recognizing digital technology's dislocating impact on home, this paper focuses on an underrepresented consumer, the female head-of-household. This interpretive research study of army men's wives elucidates three issues: the digital home's structure, technology's roles, and women's technology consumption. First, the study introduces the center–periphery model of home. Second, the results go beyond technology's tool role to building a support system. Finally, this study sheds light on the neglected area of women's play with digital technology.     

‘Hybrid’ open source software virtual communities of practice – a conceptual framework

‘Hybrid’ open source software communities are conducive to knowledge integration and innovation, and can be seen through a community of practice lens. In this paper, we develop an integrated process theory of structural attributes and social mechanisms of hybrid virtual communities. We offer a dynamic view of knowledge integration and innovation in such communities. We also emphasise the multi-faceted nature of virtual communities and identify factors that regulate participation and sustain such communities. This has implications for theorising about knowledge integration and innovation in hybrid virtual settings. Finally, virtual ethnography and multi-level research are suggested for future research.     

Fat tails,VaR and subadditivity

Financial institutions rely heavily on Value-at-Risk (VaR) as a risk measure, even though it is not globally subadditive. First, we theoretically show that the VaR portfolio measure is subadditive in the relevant tail region if asset returns are multivariate regularly varying, thus allowing for dependent returns. Second, we note that VaR estimated from historical simulations may lead to violations of subadditivity. This upset of the theoretical VaR subadditivity in the tail arises because the coarseness of the empirical distribution can affect the apparent fatness of the tails. Finally, we document a dramatic reduction in the frequency of subadditivity violations, by using semi-parametric extreme value techniques for VaR estimation instead of historical simulations.     

A characterization of exponential distributions based on order statistics

This note contains a characterization of exponential distributions based on the properties of linear transformations of order statistics. This is a certain converse of a well known theorem of Rényi about the distribution of linear combinations of order statistics from exponential distributions. Some statistical applications of the result are indicated.     

The work of mapping and the mapping of work: prosumer roles in crowdsourced maps

This paper presents an analysis of crowdsourcing work with a particular focus on exploring what forces and characteristics of the collaboration practices and technologies encourage and discourage prosumer work behaviours. Data were gathered through depth interviews with prosumers of a crowdsourced digital nautical map, observational netnographic research of prosumers on angling forums, and interviews and meetings with the map providers. Incorporating research on consumer work and prosumption, three distinct prosumer roles are identified based on how angling prosumers differentially produce and consume the crowdsourced maps. These roles show multiple behaviours along the prosumption continuum, and in so doing extend the continuum by introducing a second dimension – work as private versus public prosumer activity. It concludes by offering suggestions for marketers to engage with prosumers in crowdsourcing contexts.     

Reversal of fortune? The long-term effect of conservation-led displacement in Nepal

Building on a panel data-set using two rounds of self-administered surveys, this study assesses the long-term welfare effects of conservation-led displacement in Nepal. Empirical findings indicate that while displaced households suffered from poor land productivity and food insecurity in the first five years after displacement, they appear to be better off today, a decade since displacement, compared to non-displaced households. However, this has come at the expense of loosening social ties, increased strain on human capital and, most importantly, an overall deterioration in people’s socio-cultural wellbeing.
