Assessment and treatment of high-risk challenging behavior of adolescents with autism in an aquatic setting

Aquatic-based activities produce positive skill and health benefits for individuals with Autism Spectrum Disorder (ASD); however, aquatic contexts, such as the pool, introduce the risk of injury and drowning. This risk is heightened when individuals with ASD engage in challenging behavior in the pool context. The purpose of the study was to evaluate the effects of differential reinforcement without extinction for 2 participants diagnosed with ASD who engaged in challenging behavior when asked to transition from the pool. The treatment successfully decreased participants' transition latencies and challenging behavior during transitions from the pool for up to 2 months following treatment. Lifeguard staff rated the procedures as highly acceptable and helpful, and noted high degrees of satisfaction with improvements for each participant's behavior.     

Are the Russians as Unhappy as they say they are?

Since the 1980s, several polls in Russia have included questions about happiness. The responses to these questions were quite similar. Average happiness was low in comparison to other nations and declined over time. Ten years after the fall of communism Russians are less happy than during the communist period.There are doubts about the validity of these self-reports. One source of doubt is that these data may not reflect Russians' self-appraisals adequately, due to distortions in translation and a differential response bias. A second misgiving is that true discontent could be rather superficial, and be largely due to unfavorable comparison with the West and folklore of negativism.These qualms are checked in this article. It appears that the Russians are as unhappy as they say they are, and that they have good reasons to be so. The current unhappiness is not due to the Russian national character, but has more to do with the troublesome transitions taking place in Russian society.

Types of union participators over time: Toward a person-centered and dynamic model of participation

Previous research on union participation has been disjointed, with no clear consensus on the definition and nature of participation. Additionally, few studies have examined how participation changes over time, with those that have finding mixed results regarding its stability. We propose that these mixed and inconsistent findings are due largely to past research focusing on overall levels of participation, ignoring differences in how individuals participate. To remedy this, we adopted a person-centered approach to identify different types of union participators. Using a large sample of union members, we conducted latent transition analysis and found six union participator classes: high participators, leadership participators, formal union promoters, informal union promoters, silent supporters, and non-participators. In addition, we examined how individuals changed membership across two time points (separated by 6 years), antecedents of class membership (role tenure and union commitment), and outcomes (freerider intentions and actual financial contributions to the union's political action fund). The six classes differed uniquely, in terms of the ways people participate, changes in how people participate over time, what predicted class membership, and how class membership impacts two outcomes. The current study demonstrates that person-centered approaches can both clarify previous conflicting findings within the participation literature and predict meaningful outcomes.     

Reference groups: A missing link in career studies

Careers unfold within and are bound by multiple social contexts. Newer career concepts have postulated a growing need for personal agency in overcoming structural constraints, especially organizational and occupational boundaries. As a consequence, research has focused more on the individual than on contextual factors. In order to answer recent criticism of this unbalanced view we argue that the impact of reference groups needs to be better understood, both as social drivers of agentic behavior and as social constraints that, for instance, reduce the permeability of boundaries. Drawing on identity theories and social network literature we suggest a classification of reference groups in which social domains (e.g., organization, occupation, family, friends), types of groups (known people, abstract social categories), and functions (normative, comparative, supportive) are distinguished. The reference group classification is employed to discuss extant career research and to propose three directions for future research: a) Fuller consideration of different social domains beyond the employing organization for a more complete understanding of social influences in contemporary careers; b) exploration of the possibly growing relevance of abstract social categories as referents, especially for subjective career success; and c) systematic analysis of the interaction between normative, comparative, and supportive functions of individuals' social networks. Across these themes, possible negative influences of reference groups and effects of imposed rather than chosen referents are also to be considered. Implications of the suggested research for better understanding the interaction between structure and agency in shaping careers and career identity are discussed.     

Developments in child psychotherapy in Australia: an introduction

This article describes a type of intervention with parents that attempts to stimulate and encourage empathic imagination in relation to their child's difficult behaviour. Some barriers to this process are explored in the context of wider cultural influences, particularly as they pertain to the USA. Basic cultural assumptions about children, their emotional life and development, are contrasted to basic assumptions in British Object Relations Theory. Examples of parent consultations are offered and theoretical reference points are suggested.     

Nonlinear synthesis and co‐evolution of complex systems

Today a change is imperative in approaching global problems: what is needed is not arm‐twisting and power politics, but searching for ways of co‐evolution in the complex social and geopolitical systems of the world. The modern theory of self‐organization of complex systems provides us with an understanding of the possible forms of coexistence of heterogeneous social and geopolitical structures at different stages of development regarding the different paths of their sustainable co‐evolutionary development. The theory argues that the evolutionary channel to the observed increasing complexity is extremely narrow and only certain discrete spectra of relatively stable self‐maintained structures are feasible in complex systems. There exists a restricted set of ways of assembling a complex evolutionary whole from diverse parts. The law of nonlinear synthesis of complex structures reads: the integration of structures in more complex ones occurs due to the establishment of a common tempo of their evolution. On the basis of the theory, we can see not only desirable but also attainable futures.     

On the glass transition temperature and the elastic properties in Zr-based bulk metallic glasses

The temperature dependence of the elastic moduli was estimated from ultrasound time of flight measurements performed on bulk metallic glasses of composition Zr_{63? x} Cu₂₄Al _x Ni₁₀Co₃. Using the corresponding values at the glass transition temperature, the local atomic strain was determined. The obtained values for the critical atomic strain calculated for 8 at%?<?x?<?15 at% are close to the predicted universal criterion derived from a topological model, but may also reflect the difference in the chemical interaction that are not accounted by a topological approach.
