The omnipresence of radical uncertainty asks for a concept of causality that moves beyond the notion of predicted probabilities. Protean power is a most important contribution to move International Relations research in this direction. Yet, some of the key components need further grounding in existing concepts and debates. First, protean power should include the notion of directionality in order to be power. Second, it should allow for an analysis of the different forms of relation between protean power and different types of uncertainties. And it should focus on features of the power relationship instead of the context in which it takes place to be able to transfer it to contexts other than uncertainty.

There is an enormous interest in identifying the causes of psychiatric disorders but there are considerable challenges in identifying which risks are genuinely causal. Traditionally risk factors have been inferred from observational designs. However, association with psychiatric outcome does not equate to causation. There are a number of threats that clinicians and researchers face in making causal inferences from traditional observational designs because adversities or exposures are not randomly allocated to individuals. Natural experiments provide an alternative strategy to randomized controlled trials as they take advantage of situations whereby links between exposure and other variables are separated by naturally occurring events or situations. In this review, we describe a growing range of different types of natural experiment and highlight that there is a greater confidence about findings where there is a convergence of findings across different designs. For example, exposure to hostile parenting is consistently found to be associated with conduct problems using different natural experiment designs providing support for this being a causal risk factor. Different genetically informative designs have repeatedly found that exposure to negative life events and being bullied are linked to later depression. However, for exposure to prenatal cigarette smoking, while findings from natural experiment designs are consistent with a causal effect on offspring lower birth weight, they do not support the hypothesis that intra-uterine cigarette smoking has a causal effect on attention-deficit/hyperactivity disorder and conduct problems and emerging findings highlight caution about inferring causal effects on bipolar disorder and schizophrenia.

The business literature on the causes and consequences of downsizing has grown significantly over the last three decades. A multitude of causes has been identified. Downsizing is sometimes seen primarily as a cost-reducing response to various crises and external factors over which management has little or no control. Others see downsizing as a strategic management initiative in its own right. A considerable body of literature indicates workforce reductions often lead to negative financial and operational outcomes for the downsizing firm as well as negative psychological outcomes for victims, survivors, and executioners. This research paper represents a literature review on the causes and consequences of downsizing. It addresses a diverse body of literature and suggests an integrative framework on the typical causes and consequences of downsizing as well as outlines some challenges ahead for researchers seeking to advance the knowledge of downsizing.

Psychiatry has been, among medical disciplines, the one showing the highest conflict between a «positivist» model and the «hermeneutic» tradition. In particular, in recent years several authors have suggested that both the scientific method and a scientific mentality should be introduced in psychiatric practice and research. They claim that criteria like a strong correlation among clearly defined signs and symptoms, a high predictive value towards the outcome and therapeutical response, and a clearly defined relationship between the symptoms and etiology are necessary to accept a diagnositc entity. Since in the case of e.g. schizofrenia such requirements are not met, some authors even suggest that the concept of schizofrenia should be abandoned. The present paper aims to show that such problems are not unique to mental disease, but are common to several branches of medicine. For example, the definition and classification of cancer follow a «polythetic» criterion which is similar to the concept of «family resemblances». Also, diagnostic reproducibility is often low in other medical disciplines. The paper examines how such methodological problems could be dealt with using the tools of epidemiology.

Aims – To describe what users with schizophrenia think about the causes of their disorder. Methods – In each of the 10 participating Italian mental health centres, 25 users with schizophrenia were consecutively recruited and asked to complete the Users' Opinions Questionnaire (UOQ). Results – 150 out of 198 respondents mentioned at least one social cause for their mental disorder, and 114 reported exclusively social causes. Family conflicts were the most frequently reported social cause (21%), followed by traumas (20%), work and study difficulties (17%), and psychological disturbances (17%). Ten percent of the respondents mentioned biological causes. Biological causes were more frequently reported by users who were aware of their diagnosis of schizophrenia, whereas social causes by those who just knew they suffered from a psychosis. Difficulties in social relationships were more frequently pointed out by respondents with an earlier onset of the illness and a higher number of compulsory admissions in the previous 12 months. These users expressed more scepticism about the usefulness of the treatments they received, and perceived a greater social distance. Conclusions – Users' beliefs about the causes of their disorder should be taken into account by psychiatrists in order to improve their working alliance with them.

Although several previous scales have been developed to measure the presence and effects of the stressful demands encountered by university students, most of these have been validated with samples drawn from US universities, commonly using only undergraduate psychology students. In addition, many of the items used are from scales designed for application within general adult populations, with little focus upon the specific stressors met by students. In order to identify what are the major changes these students encounter that they find stressful, a sample of 32 university students from different degree areas within an Australian university was individually interviewed using a standardised protocol. Results indicated that (unlike US data) these students found dislocation to family, friend and partner relationships most stressful, followed by the time demands of study and financial restrictions. Limitations of the study, future research directions and implications for counsellors are discussed.

Wetlands in India supply crucial human and animal needs such as drinking water, protein production, fodder, water purification, wildlife habitat, and flood storage. Increased appreciation of uses and threats is essential to protect wetlands where justified. Three quarters of India's population is rural, it places great demands on India's wetlands and losses continue to occur. This paper is based on extensive discussions with natural resource managers, government employees, farmers, academicians, and resource users at dozens of sites in India, as well as an extensive literature search. Twelve important kinds of wetland loss are identified and mechanisms believed to be causing them discussed: (1) agricultural conversion, (2) direct deforestation, (3) hydrologie alteration, (4) inundation, (5) defoliation, (6) altered upper watersheds, (7) accumulative water demands, (8) water quality degradation, (9) wetland consolidation, (10) global climate change, (11) ground-water depletion, (12) exotic species and biodiversity. Wetland understanding, management, and Public awareness in India must continue growing if wetland resources are to remain functional.
