Attachment, maternal sensitivity, and infant temperament during the first year of life.

Families were examined at 6, 9, and 12 months in an intensive longitudinal study that included Home Behavior Attachment Q-sorts, laboratory Strange Situation assessment, home observations of infant temperament behavior on 24 occasions, observations of maternal parenting sensitivity on 12 occasions, and maternal reports of infant temperament. Maternal sensitivity was modestly related to Q-sort security and unrelated to Strange Situation classification. In contrast, observed infant temperament was more strongly related to both maternal sensitivity and Q-sort security. The relation between home and laboratory assessment of attachment security, which was at the level found in prior work ( e.g., B. E. Vaughn & E. Waters, 1990 ), remained after the effects of observed and mother reported infant temperament were partialed. Our data highlight the need to consider other factors besides maternal sensitivity in the explanation of variability in the attachment status of l-year-olds.

Re-placing Difference: Planning and Street Sex Work in a Gentrifying Area

This article provides a critical exploration of the way in which difference is registered in planning work at the local level. It is set within the current claim that Australian cities are increasingly diverse and multicultural and that planners need to develop skills to respond to such diversity (see, for example Sandercock, Australian Planner , 34(2), pp. 90-95, 1997). The article is based on a case study of planning practices related to street prostitution in St Kilda, Melbourne. It highlights some of the contradictions involved in the registering of difference in urban planning and the claims that planning is becoming more sensitive to difference. In particular, the article exposes the discrepancies evident between strategic and procedural planning work, and site-specific planning work, related to difference.     

Coal ash and risk: Four social interpretations of a pollution landscape

The purpose of this paper is to examine how cultural and natural components of landscapes interact in the context of environmental change. The paper looks at an example of a ‘pollution landscape’ through the lens of four distinct perspectives on the relationship between landscapes and society derived from the literature. The aim is both to develop a holistic understanding of the interaction of landscape and society in the case study and to explore the insights and limitations of each perspective. The case study explored in this paper concerns coal ash pollution in the city of Tuzla in Bosnia and Herzegovina. Environmental changes due to coal ash pollution in Tuzla have compromised the capacity of the landscape to provide societal needs and generated new meanings associated with the landscape. The case study shows that landscape influences local perceptions of environmental risks and as a result, local inhabitants develop risk management strategies dwelling in a pollution landscape. The paper concludes that the relationship between landscapes and societies may be understood best as an interactive complex, examining the actions performed in and by landscapes.     

Project manager's perception of the local communities' stakeholder in megaprojects. An empirical investigation in the UK

Based on an exploratory study conducted in the UK using thematic and cluster analysis, this paper investigates how the local communities' stakeholder is perceived, defined and categorized by project managers in major public infrastructure and construction projects (MPIC), and how their involvement could improve the performance of these projects. Due to the perceived benefits shortfall of MPIC, well organized actions from ‘secondary stakeholder’ groups have led to delays, cost overruns, and significant damage to the organization's reputation. Stakeholder management is an essential process which aims to maximize positive inputs and minimize detrimental attitudes by taking into account the needs and requirements of all project stakeholders. However, current project stakeholder management mechanisms are reactive rather than proactive, mainly offering an instrumental perspective, which aims to make the stakeholders comply with project needs. Therefore, a broader inclusiveness of secondary stakeholders who could be harmed by the organization's strategy, such as the local communities, is required to enhance the performance of MPIC.

A mixture-model approach to linking ADHD to adolescent onset of illicit drug use.

Prior research findings have been mixed as to whether attention-deficit/hyperactivity disorder (ADHD) is related to illicit drug use independent of conduct problems (CP). With the current study, the authors add to this literature by investigating the association between trajectories of ADHD symptoms across childhood and adolescence and onset of illicit drug use, with and without controlling for CP. In a longitudinal panel study of a community sample of 754 girls and boys recruited in kindergarten, this research question was examined with a combination of growth mixture modeling (to model parent-reported ADHD symptom trajectories) and survival analysis (to model youth-reported initiation of illicit drug use). Results revealed a 3-class model of ADHD trajectories, with 1 class exhibiting no or minimal symptoms throughout childhood and adolescence, another class showing a convex shape (an increase, then a decrease in symptoms) across time, and a third class showing a concave shape (a decrease, then a slight increase in symptoms) over time. The concave-trajectory class demonstrated significantly earlier onset of illicit drug use than the minimal-problem class, with the convex-trajectory class falling between (but not significantly different from either of the other two classes). These results did not change when the authors added CP to the model as a covariate. Implications of findings for theory and practice are discussed.

Information avoidance: Who, what, when, and why.

Although acquiring information can provide numerous benefits, people often opt to remain ignorant. We define information avoidance as any behavior designed to prevent or delay the acquisition of available but potentially unwanted information. We review the various literatures that examine information avoidance and provide a unique framework to integrate the contributions of these disparate areas of research. We first define information avoidance and distinguish it from related phenomena. We then discuss the motivations that prompt information avoidance and the factors that moderate the likelihood of avoidance. Finally, we discuss individual differences that predict preferences for information avoidance. We conclude by evaluating the current state of research on information avoidance and discussing directions for future research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Cytoprotective effect of a bilberry extract against oxidative damage of rat hepatocytes

The effect of a bilberry extract (BE, 25% anthocyanins) against oxidative damage in primary cultures of rat hepatocytes, induced by tert-butyl hydroperoxide and allyl alcohol, was investigated. BE displayed cytoprotective effects at 100 and 500 μg/ml in the MTT viability test. It protected the cells against lactate dehydrogenase leakage and lipoperoxidation products formation. Maximum protection (58%) was noted using 500 μg/ml of BE and intoxication by allyl alcohol. The observed cytoprotective effect is probably due to the antioxidant properties of its constituents, mainly anthocyanins. BE scavenged DPPH (IC₅₀ 3.99 ± 0.14 μg/ml) and enzymatically generated superoxide radical with an activity equivalent to 108 ± 7.2 U of superoxide dismutase per mg of extract. Our results support the use of bilberry and bilberry extracts in functional foods and food supplements designed for the prevention of chronic diseases associated with oxidative stress.     

Determinants of electricity demand for newly electrified low-income African households

Access to clean, affordable and appropriate energy is an important enabler of development. Energy allows households to meet their most basic subsistence needs; it is a central feature of all the millennium development goals (MDGs) and, while a lack of access to energy may not be a cause of poverty, addressing the energy needs of the impoverished lets them access services which in turn address the causes of poverty.
