title: Novel six-coordinate Aryl- and Alkyltin  complexes

authors: Lloyd, Nicholas C.

subjects: chemistry

abstract: Organo-tin compounds have wide applications as pesticides and as intermediates for organic synthesis.¹ They are invariably Sn(IV) derivatives and are generally four-coordinate.² The mixed organo/chioro compounds of the type RnSnCI4-n do however have the ability to expand their coordination numbers to five or six. This depends critically on the substituents - with four organic groups, R₄Sn, there is no tendency at all to coordinate extra ligands, while at the other extreme SnCl₄ readily forms six-coordinate [SnC1₄L₂] complexes since the electronegative halo groups increase the Lewis acidity of the tin centre.

title: Writing because I want to, not because I have to: Young gifted writers’ perspectives on the factors that “matter” in developing expertise

authors: Garrett, Lynda

subjects: gifted

abstract: The study reported on here sought to better understand the development of writing talent from the perspectives of a group of gifted adolescent female writers. Recent shifts in how giftedness and talent are conceptualized has led to an increased focus on domain-specific abilities and the importance of understanding how specific talents can be identified and supported. Gagné’s Differentiated Model of Giftedness and Talent (DMGT) (see Gagné, 2000; 2003; 2007; 2008) distinguishes between gifts and talents. Gifts represent the potential for outstanding achievement, while talents are the manifestation of this potential. Of particular interest to teachers and parents are the conditions that are influential in gifts being realised as talents – what Gagné refers to as catalysts. The participants in this study were asked to reflect on the development of their interest and ability in writing over time. Emerging from their feedback were two categories of catalysts: the intrapersonal and the environmental. For this group of students, intrapersonal catalysts were more influential to the realisation of their writing talent than environmental catalysts. This intrinsic motivation to write, and from an early age, is consistent with studies of eminent adult writers. Parents and teachers featured as important environmental catalysts. The participants in this study valued the input and support of teachers, particularly during the early years of their schooling. However, as they moved through the school system, these students felt the nature of the curriculum, and assessment practices increasingly threatened their intrinsic motivation for writing and diminished the satisfaction gained from writing at school. An unexpected outcome of this research was the important influence of music on their current writing.

title: Community-university collaborations: creating hybrid research and collective identities

authors: Cave, Jennifer Barbara Jane

subjects: collaborative

abstract: In this article we explore the politics of community-university collaborative research and activism. We are scholars based in universities as well as members of various 'communities'-queer, Pasifika and Māori-hence we regularly venture beyond the formal research spaces of the academy and enter into critical collaborative research with others working in 'the community'. In what follows we first outline collaborative community-based research literature that advocates hybrid research collectivities. Second, we give some context and background to our methodologies that have enabled us to re-think collaborative research. Third, examples from our research are offered to illustrate the ways in which collaborative research constructs new collective identities. Finally, we conclude by arguing that social science scholars working across university-community boundaries may expand and multiply hybrid research collectives, and thereby effect positive social change at many levels
