This article addresses gender differences in laughter and smiling from an evolutionary perspective. Laughter and smiling can be responses to successful display behavior or signals of affiliation amongst conversational partners—differing social and evolutionary agendas mean there are different motivations when interpreting these signals. Two experiments assess perceptions of genuine
and simulated male and female laughter and amusement social signals. Results show male simulation can always be distinguished. Female simulation is more complicated as males seem to distinguish cues of simulation yet judge simulated signals to be genuine. Females judge other female’s genuine signals to have higher levels of simulation. Results highlight the importance of laughter and smiling in human interactions, use of dynamic stimuli, and using multiple methodologies to assess perception.

This article challenges prevalent views about Gumilev’s relation to classic Eurasianism. On the basis of previously unavailable correspondence and interviews, it is argued that Lev Gumilev had substantial degree of affinity with the original Eurasian movement understood as a scholarly tradition. This was manifested both in his personal contacts with some of its key members, and in his scholarly work on the nomad history, which remained Eurasian in its spirit. However, the most significant departure from Eurasianism, under-appreciated by most scholars, was his theory of ethnogenesis, which attempted to establish a new naturalistic paradigm for study of history.

This paper provides an outline of the development of temporal thinking that is underpinned by the idea that temporal cognition shifts from being event dependent to event independent over the preschool period. I distinguish between three different ways in which it may be possible to have a perspective on time: (1) a perspective that is grounded in script-like representations of repeated events; (2) a more sophisticated perspective that brings in an fundamental categorical distinction between events that have already happened and events that are yet to come; and (3) a mature temporal perspective that involves orienting oneself in time using a linear temporal framework, with a grasp of the distinctions between past, present, and future. I propose that, with development, children possess each of these types of perspective in turn, and that only the last of these involves being able to represent time in an event-independent way.

This article outlines the changes to the definition of sexual offences in Northern Ireland following the implementation of the Sexual offences Northern Ireland Order 2008 in 2009, and its implications for nurses working with sexually active children in a range of clinical settings. The paper outlines the key changes for practice and addresses the needs of children in three different age groups with emphasis on children aged 13-15 years, and reviews mandatory reporting, the differences between the rights of children to consent and confidentiality, developmental sexual experimentation and sexual health promotion. It reviews related policy and guidance and makes clear the differences between sexual abuse and exploitation, and experimentation. It seeks to advise the Safeguarding Committee of the Department of Health Northern Ireland on how best to support nurses working with sexually active children and when this activity should be discussed with line managers and safeguarding specialists or referred to the safeguarding authorities.

The tegumental allergen-like (TAL) proteins from Schistosoma mansoni are part of a family of calcium binding proteins found only in parasitic flatworms. These proteins have attracted interest as potential drug or vaccine targets, yet comparatively little is known about their biochemistry. Here, we compared the biochemical properties of three members of this family: SmTAL1 (Sm22.6), SmTAL2 (Sm21.7) and SmTAL3 (Sm20.8). Molecular modelling suggested that, despite similarities in domain organisation, there are differences in the three proteins’ structures. SmTAL1 was predicted to have two functional calcium binding sites and SmTAL2 was predicted to have one. Despite the presence of two EF-hand-like structures in SmTAL3, neither was predicted to be functional. These predictions were confirmed by native gel electrophoresis, intrinsic fluorescence and differential scanning fluorimetry: both SmTAL1 and SmTAL2 are able to bind calcium ions reversibly, but SmTAL3 is not. SmTAL1 is also able to interact with manganese, strontium, iron(II) and nickel ions. SmTAL2 has a different ion binding profile interacting with cadmium, manganese, magnesium, strontium and barium ions in addition to calcium. All three proteins form dimers and, in contrast to some Fasciola hepatica proteins from the same family; dimerization is not affected by calcium ions. SmTAL1 interacts with the anti-schistosomal drug praziquantel and the calmodulin antagonists trifluoperazine, chlorpromazine and W7. SmTAL2 interacts only with W7. SmTAL3 interacts with the aforementioned calmodulin antagonists and thiamylal, but not praziquantel. Overall, these data suggest that the proteins have different biochemical properties and thus, most likely, different in vivo functions.

Research on admissions to care homes for older people has paid more attention to individual and social characteristics than to geographical factors. This paper considers rural-urban differences in household composition and admission rates. Cohort: 51,619 people aged 65 years or older at the time of the 2001 Census and not living in a care home, drawn from a data linkage study based on c.28% of the Northern Ireland population.Living alone was less common in rural areas; 25% of older people in rural areas lived with children compared to 18% in urban areas. Care home admission was more common in urban (4.7%) and intermediate (4.3%) areas than in rural areas (3.2%). Even after adjusting for age, sex, health and living arrangements, the rate of care home admission in rural areas was still only 75% of that in urban areas.People in rural areas experience better family support by living as part of two or three generation households. Even after accounting for this difference, older rural dwellers are less likely to enter care homes; suggesting that neighbours and relatives in rural areas provide more informal care; or that there may be differential deployment of formal home care services.

This paper attempts to situate and deconstruct the meanings associated with the term development in the context of the developing world. The arguments made highlights the deeply contested and fragmented terrain of development. The paper provides a historical overview of the changing nature of discourses on development, how the imageries of development have shifted since the postwar period. It deploys diverse meanings associated with development as a concept and as a theory. Thus development without dignity means little for those living in the margins of the society. At the same time the language of development has undergone revolutions and convulsions and the role of buzzwords and catch phrases have only helped to prolong misery in a neoliberal world. Development has become a 'one size fits all' concept shorn of cultural and regional specificities. It has been decontextualised and dehumanised to relate to targets
resulting in greater dissonance than resolution of aim and outcomes. The way forward is a better appreciation of the cultural capacity of the social groups for whom development is critical for survival. The conclusion highlights the endemic contradictions inherent in the meaning and delivery of development as a goal, especially when we seek to achieve resilient and sustainable development.
