Urban and agricultural soils: conflicts and trade-offs in the optimization of ecosystem services

On-going human population growth and changing patterns of resource consumption are increasing global demand for ecosystem services, many of which are provided by soils. Some of these ecosystem services are linearly related to the surface area of pervious soil, whereas others show non-linear relationships, making ecosystem service optimization a complex task. As limited land availability creates conflicting demands among various types of land use, a central challenge is how to weigh these conflicting interests and how to achieve the best solutions possible from a perspective of sustainable societal development. These conflicting interests become most apparent in soils that are the most heavily used by humans for specific purposes: urban soils used for green spaces, housing, and other infrastructure and agricultural soils for producing food, fibres and biofuels. We argue that, despite their seemingly divergent uses of land, agricultural and urban soils share common features with regards to interactions between ecosystem services, and that the trade-offs associated with decision-making, while scale- and context-dependent, can be surprisingly similar between the two systems. We propose that the trade-offs within land use types and their soil-related ecosystems services are often disproportional, and quantifying these will enable ecologists and soil scientists to help policy makers optimizing management decisions when confronted with demands for multiple services under limited land availability.     

Do “Clicker” Educational Sessions Enhance the Effectiveness of a Social Norms Marketing Campaign?

Abstract

Objective: Social norms campaigns are a cost-effective way to reduce high-risk drinking on college campuses. This study compares effectiveness of a “standard” social norms media (SNM) campaign for those with and without exposure to additional educational sessions using audience response technology (“clickers”). Methods: American College Health Association's National College Health Assessment questions are used to evaluate actual and perceived use. Additional survey questions assess individual exposure to the interventions. Results: The authors find “clicker” technology to be more effective than social norms poster media alone in reducing misperceptions of normative alcohol use for those students who attended clicker sessions. Conclusion: Poster SNM campaigns may be most effective when supported by group “clicker” heath-related sessions.     

Vocational Psychology and Career Guidance Practice: An International Partnership

Vast changes in the world of work spurred by rapid technological growth and globalization have called for a more inclusive, progressive, and forward thinking conceptualization of vocational theory, practice, training, and policy. Discussions across 8 discussion groups at the 2007 joint symposium of the International Association for Educational and Vocational Guidance, Society for Vocational Psychology, and National Career Development Association addressed various topics in the field of vocational psychology and career guidance. Several themes emerged that have captured the attention of career scholars and practitioners across the globe: culture and context in theory and practice, research as a process within a contextual system, partnership and collaboration, and social responsibility and public policy.     

Compensation for inconvenience: The utility of shift systems

Abstract

This study is part of a larger study airned at the development of a system for quantifying the inconvenience of shift schedules and schedule characteristics. The results can be used to reduce inconvenience (counter-value compensation) and to compute the monetary (counter-weight) compensability of shift schedules. The results presented here show that consensus exists among subjects from different organizations and with different background characteristics on the utility of several features, e.g. working at inconvenient hours, the irregularity of a schedule, and working during the evening (which has a positive value). The opinions slightly differ with respect to some other characteristics, such as very long shifts, work during the weekend and the average sequence length. The differences are possibly due to job characteristics.     

Income inequality and participation: A comparison of 24 European countries

Previous research suggests that when there is a high level of inequality, there is a low rate of participation. Two arguments are generally offered: First, inequality depresses participation because people from different status groups have fewer opportunities to share common goals. Second, people may participate more in civic and social life when they have more resources. However, until now, these explanations have not been separated empirically. Using EU-SILC data for 24 European countries, we analyze how income inequality is related to civic and social participation. Our results indicate that the main effects of inequality manifest via resources at the individual and societal level. However, independent of these resources, higher inequality is associated with lower civic participation. Furthermore, inequality magnifies the relationship between income and participation. This finding is in line with the view that inter-individual processes explain why inequality diminishes participation.     

Confronting or Complementing? A Case Study on NGO–State Relations from Kerala, India

NGOs have, of late, found some of their traditional domains, such as provision of micro-credit and participatory development, coinciding with or being taken away by the state. How do they position themselves and retain relevance vis-a-vis the state in the changed scenario? Tracing the trajectory of interventions of a local NGO in Kerala, India, this article shows that NGOs exhibit ‘multiple identities’—selective collaboration, gap-filling and posing alternatives—in the process of engagement with the state. The ‘strategizing’ of such identities may hold the key to their relevance vis-a-vis the state.     

Acculturative Stress and Mental Health Among Korean Adolescents in the United States

This study investigated Korean-American adolescents' stress related to their acculturation experiences and mental health. A total of 260 Korean-American adolescents from immigrant families (ages 12–18 years) participated in the study. The U.S. born group had a higher level of acculturative stress than the Korea-born group (t = 2.222; df = 258; p < .05). Males reported a higher level of self-esteem than females (t = ?2.112; df = 257; p < .05). Acculturative stress was positively correlated with depression (r = .299; p < .01) and negatively related to self-esteem (r = ?.292; p < .01). Self-esteem was negatively related to depression (r = ?.536; p < .01).
