Land-use and environmental pressures resulting from current and future bioenergy crop expansion: A review

Recent energy and climate policies, particularly in the developed world, have increased demand for bioenergy² as an alternative, which has led to both direct and indirect land-use changes and an array of environmental and socio-economic concerns. A comprehensive understanding of the land-use dynamics of bioenergy crop production is essential for the development of sustainable bioenergy and land-use policies. In this paper, we review the patterns and dynamics of land-use change associated with bioenergy crops (hereafter referred to as ’bioenergy-driven land-use change’). The review focuses on four regions as the most prominent locations in which these patterns and changes occur: Brazil; Indonesia and Malaysia; the United States of America (U.S.A.); and the European Union (EU). The review confirms that bioenergy-driven land-use change has affected and will impact most severely on the ’land- and resource-abundant’ developing regions, such as Brazil, where economic development takes priority over sustainable land-use policies, and the enforcement capability is limited. Opportunities for more effective policy are available through the development of international climate change policy (e.g. REDD under the UNFCCC), and certification criteria for sustainable bioenergy products (e.g. EU RED). However, bioenergy produced from no and/or less land-using feedstocks (e.g. wastes and residues), and their associated technologies must be given higher priority to minimise bioenergy-driven land-use change and its negative impacts.     

Convergence theorems of willingness-to-pay and willingness-to-accept for nonmarket goods

This paper shows that the disparity between an agent’s willingness-to-pay and willingness-to-accept for a nonmarket good becomes small and the two values converge to the same limit only if the agent’s initial consumption level of the numéraire is large enough. A necessary and sufficient condition for convergences is provided, and a formula is provided to compute the limit value directly from a utility function. These convergence results are derived when the nonmarket goods are indivisible and qualitatively differentiated, and then extended for the divisible case.     

Patient-Centered Approach to Building Problem Solving Skills Among Older Primary Care Patients: Problems Identified and Resolved

This article describes problems identified by older primary care patients enrolled in Problem Solving Therapy (PST), and explores factors associated with successful problem resolution. PST patients received 1 to 8, 45-min sessions with a social worker. Patients identified problems in their lives and directed the focus of subsequent sessions as consistent with the steps of PST. The 107 patients identified 568 problems, 59% of which were resolved. Most commonly identified problems included health related issues such as need for exercise or weight loss activities, medical care and medical equipment needs, home and garden maintenance, and gathering information on their medical condition. Problems identified by patients were 2.2 times more likely to be solved than those identified by a health care professional. Using PST in primary care may facilitate patients in addressing key health and wellness issues.     

The attractive voice: What makes it so?

Previous research has shown that more attractive voices are associated with more favorable personality impressions. The present study examined which acoustic characteristics make a voice attractive. Segments of recorded voices were rated on various dimensions of voice quality, attractiveness, and personality impressions. Objective measures of voice quality were obtained from spectrogram analysis. Overall, the subjective ratings of voice quality predicted vocal attractiveness better than the objective measures. When vocal attractiveness was regressed onto both subjective and objective measures, the final regression equation included 8 subjective measures, which together accounted for 74% of the variance of the attractiveness scores. It also was found that the measures of voice quality accounted for variance in favorableness of personality impressions above and beyond the contribution of vocal attractiveness. Thus, attractiveness captures an important dimension of the voice but does not cover all aspects of voice quality.This research was supported by National Institute of Mental Health Grant MH40498.     

The vocal attractiveness stereotype: Replication and elaboration

We examined personality impressions on five NEO subscales (Costa & McCrae, 1985) as a function of senders' vocal and physical attractiveness. There were four major findings: (a) both vocal and physical attractiveness produced more favorable ratings, and these effects were more pronounced in a single channel (voice only or face only, respectively) than in a multiple channel (voice plus face); (b) the influence of attractiveness, both vocal and physical, was moderated by subscale—the effect of vocal attractiveness was most pronounced for Neuroticism and nonexistent for Agreeableness; the effect of physical attractiveness was most pronounced for Extraversion and nonexistent for Conscientiousness; (c) a vocal attractiveness × physical attractiveness interaction indicated that effects of the two stereotypes were particularly strong for senders who were attractive on both channels; (d) the effects of attractiveness, both vocal and physical, diminished when judges were familiar with the target persons.This research was supported in part by National Institute of Mental Health Grant RO1 MH 40498.

Between- and within-group wage inequalities, and the advent of new technology

We present a simple model that explains two features of the dynamics of wage inequalities: between-group and within-group. Individuals are assumed to be heterogeneous in their innate abilities. With the advent of a new technology, each individual decides whether or not to acquire the skill for the new high-tech sector. The heterogeneity explains not only the between-group wage inequality but also the within-group wage inequality, which are observed in advanced countries such as the US and UK.     

Evaluation through collaboration: a model program of agency-based training in geriatric social work

The Institute for Geriatric Social Work (IGSW), located at Boston University School of Social Work (BUSSW), formed a collaborative partnership with Elder Services of the Merrimack Valley (ESMV), a large urban Area Agency on Aging (AAA) near Boston to design, implement, and evaluate an innovative model program of agency-based training for practicing social workers. The collaboration facilitated and strengthened the development of a program that benefited the university-based program and the community-based agency. The training program comprises a "blended" model of core and elective online courses combined with face-to-face training. Evaluation of the model program is integral to its design, and includes a randomized control trial to test the effectiveness of the training program in increasing practice competencies.
