On the unique features of post-disaster humanitarian logistics

Logistic activity can be thought of as a socio-technical process whereby a social network of individuals orchestrates a series of technical activities using supporting systems such as transportation and communications. To understand the functioning of the entire system requires proper consideration of all its components. We identify seven key components: the objectives being pursued, the origin of the commodity flows to be transported, knowledge of demand, the decision-making structure, periodicity and volume of logistic activities, and the state of the social networks and supporting systems. Based on our analysis of the differences between commercial and humanitarian logistics, we pinpoint research gaps that need to be filled to enhance both the efficiency of humanitarian logistics and the realism of the mathematical models designed to support it.We argue that humanitarian logistics is too broad a field to fit neatly into a single definition of operational conditions. At one end of the spectrum we find humanitarian logistic efforts of the kind conducted in long-term disaster recovery and humanitarian assistance, where operational efficiency – akin to commercial logistics – is a prime consideration. At the other, post-disaster humanitarian logistic operations involved in disaster response and short-term recovery activities represent a vastly different operational environment, often in chaotic settings where urgent needs, life-or-death decisions and scarce resources are the norm. The huge contrast between these operational environments requires that they be treated separately.     

Comparisons of the Educational Value of Distance Delivered versus Traditional Classroom Instruction in Introductory Agricultural Economics

As many universities are promoting distance courses, the comparative advantages and disadvantages over conventional classroom delivery are being debated. Student attitudes and test performance in an introductory microeconomics course are compared across the two different course delivery formats. Results show that students with average or below-average college aptitude test scores perform more poorly in the distance class.     

Impact at the ‘Bottom of the Pyramid’: The Role of Social Capital in Capability Development and Community Empowerment

Rooted in the notion of inclusive capitalism, the Bottom‐of‐the‐Pyramid (BoP) approach argues for the simultaneous pursuit of profit and social welfare by creating markets for the poor. This idea has been both celebrated and criticized in the literature. We do neither in this paper. Instead, by leveraging insights from Amartya Sen's work on capability development and the literature on social capital, we offer a more socially embedded and community‐centric BoP approach. By redefining poverty not just as a lack of income, but also as a lack of ‘capabilities’ in Sen's sense that can be developed through leveraging social capital, we offer a systemic framework for understanding the societal impact of business‐driven ventures in the BoP and empowering BoP communities through these ventures. Specifically, we argue that any business initiative in the BoP ought to be evaluated on the basis of whether it advances capability transfer and retention by (a) enhancing the social capital between a particular community and other more resource rich networks, and (b) preserving the existing social capital in the community.     

Public and private intervention for next-generation access deployment: Possibilities for three European countries

How next-generation access (NGA) deployment can be encouraged is a challenge that many countries are facing, and one that has been widely and actively discussed around the globe. This discussion has highlighted a dilemma that ultimately shapes investment—how to encourage the widespread deployment of NGA while enabling operators to achieve reasonable returns. This paper focuses on the tensions that arise as a consequence of this investment challenge in three countries – the Netherlands, Sweden and the United Kingdom (UK) – and uses the analysis of extensive data collection with k7ey actors to argue the case for the injection of public or private incentives. The paper finds that markets with competitive infrastructure will not benefit from public investment while markets with geographical constraints are in need of public support. The paper also explains that regulatory intervention is necessary in the early stage of NGA roll-out, even in currently competitive markets. In all the discussions it becomes evident that, among the three cases, the UK is most in need of public intervention.     

Compulsive consumption behaviours: investigating relationships among binge eating,compulsive clothing buying and fashion orientation

Compulsive buying and binge eating are examples of compulsive consumption behaviours, and for individuals with these behavioural tendencies, appearance and appearance‐related products seem to be of paramount importance. The purpose of this research was to determine if bulimic behaviours, fashion interest and the importance of being well dressed had a causal relationship with compulsive clothing buying. Subjects completed a compulsive clothing buying scale, the binging/control subscale of the Bulimia Test‐Revised and a fashion orientation scale. A path analysis indicated that binging behaviours and fashion interest significantly predicted compulsive clothing buying, while binging behaviours were not significantly related to fashion interest or the importance of being well dressed. Such findings may suggest that female consumers compulsively buy clothing for different reasons and/or motivations.     

The relationship between wage growth and wage levels

We estimate the covariance between the permanent component of wages and a random coefficient on experience in models both with potential experience and with actual experience. Actual experience is allowed to be arbitrarily correlated with both the permanent component of wages and the random component on experience. We find no evidence that workers of higher ability experience faster wage growth. Our point estimates suggest that a worker with a one standard deviation higher level of permanent ability would have a return to annual potential experience that is 0.61 of a percentage point lower. The analogous point estimate for actual experience is 0.87 of a point lower. Contrary to the popular perception, wage growth among low‐skill workers appears to be at least as high as that for a medium‐skilled worker. Copyright © 2009 John Wiley & Sons, Ltd.     

A picture tells a thousand words: Impact of an educational nutrition booklet on nutrition label gazing

Overweight and obesity are major health issues in many countries. Nutritional labels provide a means to making healthier food choices. Gazing longer at nutrition labels rather than the products' packaging may be a first step in making a healthy decision when purchasing or consuming a product. Using eye-tracker methodology, we examined the influence of an educational nutrition booklet on duration of gaze at nutrition labels. Thirty-two adults from New York City participated in a pretest–posttest study. Participants were randomly assigned to the nutrition education group (NE) or the control group for 10 min. The NE group reviewed a picture-based educational nutrition booklet. The control group worked on a word find puzzle. Participants' duration of gazing at nutrition labels was assessed. Results revealed a significant interaction of group and nutrition label gazing such that the NE group gazed significantly longer at the nutritional label in the posttest compared to the pretest. The NE group gazed significantly longer at nutrition labels during the posttest than the control group. There was no effect for the control group. The findings show that briefly reviewing an educational nutrition booklet increases duration of gaze at nutrition labels.     

Taking Terrain Literally: Grounding Local Adaptation to Corporate Social Responsibility in the Extractive Industries

Since the early 1990s, the extractive industries have increasingly valued corporate social responsibility (CSR) in the communities where they operate. More recently, these industries have begun to recognize the importance of adapting CSR efforts to unique local contexts rather than applying a one-size-fits-all model. However, firms understand local context to mean culture and treat the physical properties of the host region—topography, geology, hydrology, and climate—as the exclusive purview of mineral geologists and engineers. In this article, we examine the organization of CSR at two industrial-scale gold mines in Guatemala, owned by the same firm, which yielded starkly distinct levels of support among host community residents. We develop the idea of social terrain to convey the way in which the biophysical environment informs local social relations and imbues phenomena with particular social meanings. We argue that firms must account for social terrain in organizing for CSR. The literature struggles to provide guidelines for identifying and understanding stakeholders. Social terrain, we argue, can begin to bridge this gap between theory and practice.     

Adoption potential of nitrate mitigation practices: an ecosystem services approach

Nitrate pollution from agricultural drainage has caused water quality concerns worldwide, but there are several promising technologies to help mitigate this environmental degradation. While these practices primarily aim to improve water quality, they may also provide other ‘additive’ benefits or ecosystem services and the awareness of such benefits may influence their potential to be adopted by farmers. To investigate the impact that perceived ecosystem services has on a practice's adoption potential, we used a mixed methods approach consisting of a literature review, producer surveys, and a group discussion to explore farmer interest in and perceived benefits (on-farm and regional) of seven subsurface drainage nitrate reduction practices (controlled drainage, bioreactors, wetlands, nitrogen management rate, nitrogen management timing, cover crops, and diversified crop rotations). The nitrogen management practices were shown to be accessible and realistic options for water quality improvement as they elicited high interest and had the highest level of compatibility. However, these practices did not provide many other complementary ecosystem services. Conversely, wetlands had a high literature review-derived ecosystem service count, but were considered to have low compatibility, and survey respondents indicated less interest in this practice. The practice of cover cropping showed more moderate, yet consistently positive results for all factors.     

Residential Fixed Investment and the Macroeconomy: Has Deregulation Altered Key Relationships?

Financial deregulation in 1980 potentially altered key relationships between residential fixed investment (RFI) and key macroeconomic variables. This study uses a vector error correction model to examine relationships between RFI, money, interest rates, and output in pre-deregulation and post-deregulation sub-periods. Results indicate short-term interest rate shocks account for much of RFI variability pre-deregulation. After deregulation, long-term FHA interest rate shocks better account for RFI movements. Results also show that, in the post-deregulation era, RFI shocks have increased predictive power for overall gross domestic product movements. Thus, the study finds altered relationships between RFI and macroeconomic variables.
