Who Will Feed China in the 21st Century? Income Growth and Food Demand and Supply in China

This study uses resource‐based measures to explore the evolution of China's demand and supply for food. China's dietary shift from plant to animal‐based foods, induced by its income growth, is likely to impose considerable pressure on agricultural resources. China's demand for food on this measure appears consistent with global trends, while China is an out‐performer on the supply side, producing much more food than its income level and land endowment would predict. China's current per capita income is in a range where consumption growth is high and in excess of production growth, but the gap between supply and demand is likely to diminish as population and per capita consumption growth decelerate. Continuing agricultural productivity growth and sustainable resource management will be important influences on the growth of China's future net import demand for food.     

Work motivation and public service motivation: disentangling varieties of motivation and job satisfaction

Research on motivation in the public sector has used public service motivation (PSM) and self-determination theory (SDT) interchangeably. This paper compares both theories, develops hypotheses pertaining to their assumptions, and empirically tests them in two public offices in Switzerland. We then explore their relationship with job satisfaction as an indicator of predictive validity. We find that SDT and PSM display conceptual differentiation and SDT has a strongest relationship to job satisfaction. However, moderation analysis suggests that employees with high levels of PSM have more stable job satisfaction compared to their low-PSM counterparts.

Doing what comes naturally? Why we need a practical ethics of teamwork

This paper challenges the belief that teamwork is a ‘natural’ form of work organization that satisfies universal human needs such as social affiliation and self-actualization. A corollary of this belief–that teamwork is a morally superior form of work organization–unnecessarily restricts debate about the desirability and usefulness of teams because any criticism comes to be seen as a denial of our essential humanity. Using an approach inspired by Michel Foucault's concept of ‘care of the self’, I will propose a practical ethics of teamwork that allows us to appreciate the moral ambiguities of teamwork.     

Relationships among consumer vanity,gender, brand sensitivity,brand consciousness and private self‐consciousness

The purpose of this study was to examine relationships among consumer vanity, gender, brand sensitivity, brand consciousness and private self‐consciousness within a context of social comparison theory. The four dimensions of consumer vanity are concern for and positive view of physical appearance and concern for and positive view of achievement. Participants were 400 college students (284 women; 116 men). Participants above the median in three of the four dimensions of vanity (except vanity achievement view) were more sensitive to and more conscious of brand names. Participants above (vs. below) the median in vanity achievement view scored higher on private self‐consciousness. Women scored higher on brand sensitivity, brand consciousness and private self‐consciousness than men. There was a significant correlation between brand sensitivity and brand consciousness. Results support the notion that consumers’ decisions, especially regarding brand names, may be guided by vanity‐related concerns and views.

Guerrilla‐style Defensive Architecture in Detroit: A Self‐provisioned Security Strategy in a Neoliberal Space of Disinvestment

Self‐provisioning has long been an important component of urban political economic processes. However, it has recently become a central feature of grassroots urban governance strategies as well. In tumultuous cities of the twenty‐first century, with governments either unwilling or unable to effectively enforce zoning laws, police neighborhoods or manage infrastructure, some householders have begun performing these services instead. This article examines one subset of self‐provisioning practices that has emerged in southwest Detroit where residents have taken steps to secure abandoned housing as a means of exerting social control over their living environment. These actions embody many contradictions and ethical dilemmas, and the intimate scale of action has left the structural production of disinvestment in places like Detroit largely unchecked. Nevertheless, these guerilla‐style spatial interventions have emerged as critically important response strategies helping residents reduce their vulnerability and stabilize their blocks even as other nearby areas continue to experience decline.     

Migration,self‐selection and income distributions

Self‐selection in rural–urban migration is examined using three datasets from rural and urban China in 2002. We construct a migrant sample including both migrants who converted their hukou status from rural to urban (permanent migrants) and those who did not (temporary migrants). We find a strong positive selection for permanent migrants, but the selection for temporary migrants is ambiguous. We reach these conclusions by comparing migrants' counterfactual wage densities, assuming they are paid as rural local workers, to actual wage densities of rural local workers. Our results imply that permanent migration has negative effects on rural human capital accumulation and income levels.     

Consumer self‐construal and trust as determinants of the reactance to a recommender advice

Commercial recommendation agents (RAs) represent an important type of the decision support systems (DSSs) that are widely used by online retailers and firms. To date, little is known about the factors that shape the user's decision making and reactance toward the recommendations of these agents. Building on theories from psychology and information systems domains, this research proposes that a user's self‐construal and trust are two relevant factors that interact to shape the behavior toward the RA advice. Two studies, the first conducted using potential online customers and the second conducted at a behavioral laboratory, provided support to this proposition. The first study considered RA trust and showed that activating the interdependent self leads users with low (high) trust to exhibit high reactance behavior toward the RA advice. The second study variated trust using trust cues and corroborated the latter finding, while showing no important impact for the psychological reactance trait. As expected, in both studies the reactance behavior of independent users was not affected by trust. These results contribute by underscoring that social interdependence extends to RAs because the role of trust becomes salient when the interdependent self is activated for a user.
