Sexual Identity Formation of Women Who Love Women: A Contextual View Point

Nonheterosexuals experience oppression and discrimination that affect personal development on all levels. An increased awareness of sexual identity development could create more inclusive sexual identity models, better understanding for counselor educators, and better training for counselors on issues of sexual identity. The purpose of this study was to identify the life experiences that influence sexual identity in women who love women. This study required that participants attach meaning to sexual identity formation. From the data collected, four themes emerged: I was just different, information seeking, view of self as a woman within the context of culture, and contextual relationships. Findings of this study did not support a stage model of sexual identity development. Instead, this study supported the view that sexual identity is fluid and strongly related to relationships with peer groups.     

Transformational leadership and leader moral orientation: Contrasting an ethic of justice and an ethic of care

Previous research on the moral foundations of transformational leadership has focused on a Kohlbergian (1969, 1976) ethic of justice. However, proposed associations between level of justice reasoning and transformational leadership have received only partial support. We reasoned that an ethic of care would be more consistent with the nature of transformational leadership than would be an ethic of justice. Multilevel regression analyses on data obtained from a sample of leaders (N = 55) and followers (N = 391) at a Canadian university supported our predictions. Specifically, leader propensity toward using an ethic of care was significantly, positively related to follower perceptions of transformational (but not transactional) leadership. Leader propensity toward an ethic of justice was significantly, positively related to follower perceptions of transactional (but not transformational) leadership. Conceptual, research, and practical implications are discussed.     

Knowledge work as organizational behavior

Knowledge work has been defined as a profession, a characteristic of individuals, and as an individual activity. We review and critique these definitions of knowledge work and propose that knowledge work is best understood as discretionary behavior in organizations. As such, knowledge work is understood to comprise the creation of knowledge, the application of knowledge, the transmission of knowledge, and the acquisition of knowledge. Each of these activities is seen as a discretionary behavior. Employees are likely to engage in knowledge work to the extent that they have the (a) ability, (b) motivation, and (c) opportunity to do so. The task of managing knowledge work is focused on establishing these conditions. Organizational characteristics such as transformational leadership, job design, social interaction and organizational culture are identified as potential predictors of ability, motivation and opportunity. Implications for further research and practice are identified.     

Markov Random Fields with Higher-order Interactions

Discrete-state Markov random fields on regular arrays have played a significant role in spatial statistics and image analysis. For example, they are used to represent objects against background in computer vision and pixel-based classification of a region into different crop types in remote sensing. Convenience has generally favoured formulations that involve only pairwise interactions. Such models are in themselves unrealistic and, although they often perform surprisingly well in tasks such as the restoration of degraded images, they are unsatisfactory for many other purposes. In this paper, we consider particular forms of Markov random fields that involve higher-order interactions and therefore are better able to represent the large-scale properties of typical spatial scenes. Interpretations of the parameters are given and realizations from a variety of models are produced via Markov chain Monte Carlo. Potential applications are illustrated in two examples. The first concerns Bayesian image analysis and confirms that pairwise-interaction priors may perform very poorly for image functionals such as number of objects, even when restoration apparently works well. The second example describes a model for a geological dataset and obtains maximum-likelihood parameter estimates using Markov chain Monte Carlo. Despite the complexity of the formulation, realizations of the estimated model suggest that the representation is quite realistic.     

Forced Migration,Climate Change,Mitigation and Adaptive Policies in Mexico: Some Functional Relationships

Natural disasters related to hydro-meteorological events have increased during the last few decades, both in frequency and severity. Mexico is heavily exposed to climate change, but has also suffered in the past from climate variability ( Blümel, 2009 ). The new risks oblige the government to develop mitigation processes, while the affected people are implementing strategies of adaptation and resilience-building, mostly at the family and community level. This includes forced migration due to climate change into the slums of megacities or illegal immigration to the United States. The arid, semi-arid and subhumid condition of 49.2 per cent of the territory of Mexico is seriously affected by climate change. In addition, poverty and the lack of jobs have created complex livelihood situations, in which young people leave rural areas, partly due to socio-economic pull factors. In this paper, we address the functional relationships between climate patterns and migration processes in Mexico, highlighting the linkages between the origin of migrants, their economic activity and their vulnerability to extreme events and we discuss long-term climate patterns. Agriculture still uses 78 per cent of the available water in Mexico. In the drylands the competition for water use requires an integrated policy to deal with the new threats from climate change, including mitigation from the top down and adaptation processes from the bottom up to reduce the social vulnerability of the rural population in the highly affected drylands of the central and northern parts of Mexico. The new policy for administering water resources, which promotes the efficient use of an increasingly scarce and polluted resource, still suffers from a lack of participation by the affected rural population. In this paper, we propose an integrated management system from the watershed onwards, involving socio-economic, political, cultural and hydrological variables, to deal with the rising scarcity of water, and the uncertainty and complexity of climate change.     

Social Exclusion in Britain 1991—1995

The purpose of this paper is to offer a working definition of social exclusion and to operationalize it in such a way that an initial empirical analysis of social exclusion in Britain today can be undertaken. After a brief review of conceptions of social exclusion and some of the key controversies, we operationalize one definition based on the notion of participation in five types of activity—consumption, savings, production, political and social. Using the British Household Panel Survey, indicators for participation on these dimensions are developed and analysed both cross-sectionally and longitudinally for the period 1991–5. We find strong associations between an individual's participation (or lack of it) on the five different dimensions, and on each dimension over time. However, there is no distinct group of socially excluded individuals: few are excluded on all dimensions in any one year and even fewer experience multiple exclusion for the whole period. The results support the view that treating different dimensions of exclusion separately is preferable to thinking about social exclusion in terms of one homogeneous group.
