Audience effects on solitary faces during imagery: Displaying to the people in your head

Subjects imagined situations in which they reported enjoying themselves either alone or with others. Electromyographic (EMG) activity was recorded bilaterally from regions overlying thezygomatic major muscles responsible for smiling. Controlling for equal rated happiness in the two conditions, subjects showed more smiling in high-sociality than low-sociality imagery. In confirming imaginary audience effects during imagery, these data corroborate hypotheses that solitary facial displays are mediated by the presence of imaginary interactants, and suggest caution in employing them as measures of felt emotion.Avery Gilbert and Amy Jaffey had compelling insights throughout the course of study.

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.     

"We just happen to live here": two social workers share their stories about Oregon's Death with Dignity Law

This article is written more like a conversation with the reader rather than a strictly academic piece. The purpose is to share from a more personal perspective the unique circumstances and challenges faced by two social workers in Oregon as they grappled with the Death with Dignity Law. The law has been in effect for six years and a May 2004 decision from the Ninth U.S. Circuit Court allowed the law to remain a legal end-of-life option. Each writer has a unique voice on the process of social work involvement in practice, research, and policy since the law was originally passed in 1994.     

Education and Poststroke Separation Among Couples With Mutual Children

The objective of this study based on Swedish registers is to examine the influence of socioeconomic position on poststroke divorce and separation using education as a marker. People aged 18 to 64 who suffered a first stroke between 1992 and 2005 were included if they were married or cohabiting and had mutual children. The material included 42,026 first stroke cases and 424,281 nonexposed persons, both populations divided into three different educational groups. Results show that the risk of separation is much higher in the incident year and in the first poststroke year, above all among people with only compulsory (elementary) education.     

Agriculture,Pesticide Use,and Economic Development: A Global Examination (1990–2014)

Modern agricultural production typically requires large quantities of chemical pesticides, a potential source of both environmental and human harm. Previous social science research has suggested that environmental problems such as those associated with pesticide use may begin to decline at higher levels of economic development. Using fixed effects models, we examine whether this possible relationship holds within nations and over time. This study draws on data from the World Bank as well as pesticide use data from the Food and Agriculture Organization of the United Nations to examine the relationship between pesticide use and economic development within nations from 1990 to 2014. The findings are considered from theoretical perspectives in environmental sociology on the drivers of environmental impacts: the treadmill of production theory, structural human ecology, ecological modernization theory, and the environmental Kuznets curve hypothesis. The results of this study show a positive relationship between economic development and pesticide consumption over time, with no decline in use at higher levels of economic development. Thus, they generally support the claims made by treadmill of production and structural human ecology.     

Locating social service centres using interactive graphics

The paper explores the feasibility of using interactive graphic based solution procedures in location problems with discrete choices. It compares solutions generated through interactive graphics with those generated through optimization for a problem context where service centres had to be located in rural India. The comparison demonstrates the feasibility of generating near optimal solutions for problems with a certain dimensionality. Broad features of the graphic software are described. The paper also highlights other advantages and limitations of the interactive graphic procedure.     

A model for national planning policies

This paper attempts to develop a multiobjective model to help policy-makers choose the most appropriate mix of economic policies concurrent with the elimination of serious gaps. Each individual policy attempts to achieve a specific goal or a set of subgoals; but it may hinder the achievement of some other subgoals. To differentiate between the importance of different objectives, the analyst assigns different priorities to each of the given set of subgoals. Three sets of results are provided by three separate computer runs of this model. Each set of results corresponds to one of the three priority structures, and each run indicates quite differing underachievements or over-achievements of individual subgoals. A detailed explanation for each of these deviations (gaps) from the targeted subgoals is attempted in an overall framework and some interactions between various gaps (savings gaps, foreign exchange gap, domestic growth gap, GNP gap, etc.) are also identified.     

Disability as a Phenomenon: a discourse of social and biological understanding

This paper addresses conceptualisations of disability and what it constitutes as a category in a social security system. It argues that the conceptualisation of disability involves a discourse about definitions. This means it is an ongoing debate about principles or which determinators to use presenting the 'correct' understanding of disability as a phenomenon. The disability discourse involves a contest between a biological and social understanding of disability. This paper discusses which domains of interest are produced by each of these understandings. They are based on empirical findings when analysing rights of entitlement to a disability programme in the Swedish social security system. The study followed documentation of the public debates for a period of 25 years and extracted what was communicated as constituting disability in these debates. Which definition to give disability by this social security programme appeared as being a continuous contest between medical and social understanding. The paper argues that, rather than approaching the biological understanding as representing an antiquated concept to disability and the social model as a modern conceptualisation, these understandings are competitive. This makes disability into a flexible and heterogeneous concept, a term difficult to give a specified and limited meaning.     

Conversations at the end of life:the challenge to support patients who consider death with dignity in Oregon

Oregon's Death with Dignity Act (ODWDA) has been in effect for eight years. The United States Supreme Court recently decided that Oregon's law did not violate the Controlled Substances Act. Other states may consider a law similar to Oregon's through legislative process or ballot measures. Although social work is not mentioned in the law, our profession interfaces with the terminally ill, particularly in hospice. Eighty-seven percent of those who have used the law were enrolled in a hospice program. As a pilot project, this article explores conversations that the authors have had with patients, families, team members and health systems in hospices and oncology settings under Oregon's unique environment. The following four themes emerged from these conversations: (1) mental health, education, choice; (2) team concerns; (3) family issues; and (4) values, ethics, restricted conversations and professional struggles.
