Everything should be as simple as possible, but no simpler: towards a protocol for accumulating evidence regarding the active content of health behaviour change interventions

Abstract: There is a need to consolidate the evidence base underlying our toolbox of methods of behaviour change. Recent efforts to this effect have conducted meta-regressions on evaluations of behaviour change interventions, deriving each method's effectiveness from its association to intervention effect size. However, there are a range of issues that raise concern about whether this approach is actually furthering or instead obstructing the advancement of health psychology theories and the quality of health behaviour change interventions. Using examples from theory, the literature and data from previous meta-analyses, these concerns and their implications are explained and illustrated. An iterative protocol for evidence base accumulation is proposed that integrates evidence derived from both experimental and applied behaviour change research, and combines theory development in experimental settings with theory testing in applied real-life settings. As evidence gathered in this manner accumulates, a cumulative science of behaviour change can develop.

Isotope geochemistry of the 1985 Tibet Geotraverse, Lhasa to Golmud

Abstract: Geochronological data from the Golmud —Lhasa section across the Tibetan Plateau indicate progressively younger periods of magmatism from north to south associated with successively younger ocean closures. Pre -collision Eocene magmatism (50—4 0 Ma) exposed along the southern margin of the Lhasa Terrane in the Gangdise Belt resulted from anatexis of mid -Proterozoic crust (~ 1000 Ma) at depths greater than 10 km, but at higher crustal levels subduction-related intrusions were predominantly mantle-derived with ~ 30 % crustal assimilation . Intrusions from the northern Lhasa Terrane are early Cretaceous in age (130 —110 Ma). These form a bimodal suite comprised of two-mica granites derived from anatex is of Mid -Proterozoic crust and of biotite -hornblende granodiorites from about 60 % crustal assimilation by mantle magmas above a post-collision subduction zone. They place a minimum constraint on collision between the Lhasa and Qiangtang Terranes of 130 Ma . Granite magmatism from the Kunlun Mountains is late P ermian -early Jurassic in age (260—190 Ma). The Kunlun batholith represents reworked mid-Proterozoic crust (1400 —1000 Ma) at an active continental margin from 260 —2 4 0 M a . Post-tectonic granites were emplaced in a post-collision setting (200 -190M a). Collision between the Qiangtang and Kunlun Terranes is dated as end -Triassic. Nd model ages of sediments from across the plateau record up lift and erosion of young source regions throughout the Phanerozoic confirming that the Tibetan Plateau is the site of multiple continental collision through time. Phanerozoic magmagenesis throughout the plateau requires considerable crustal reworking and limited crustal growth which suggests thickened continental crust in the region may predate the most recent Eocene collision.

The whereabouts of power: politics, government and space

Abstract: In a world where it has become almost commonplace to talk about power as centralised or distributed, concentrated or diffuse, deterritorialized or dispersed even, it is all too easy to miss the diverse geographies of power that put us in place. The binary talk that forces us to choose between a centred or a decentred view of power, or to shuffle between them in an effort to blur clearly demarcated scales, leaves little room to move beyond defined distances and settled proximities in relation to the exercise of power. In this paper, a more spatially‐curious dialogue of power is opened up which foregrounds associational as well as instrumental forms of power which can make a difference to how we act politically.

The Boundary Approach of Competence: A Constructivist Aid for Understanding and Using the Concept of Competence:

Abstract: Although competence is an important concept in human resource development and education, there is no theoretical framework for competence. This article focuses on the development of such a theoreti...

‘Just teach us the skills please, we'll do the rest’: empowering ten‐year‐olds as active researchers

Abstract: This paper discusses the outcomes of an initiative to empower ten-year-olds as active researchers. It debates some of the barriers that are commonly cited with regard to children of this age taking ownership of their own research agendas—power relations, competence, knowledge and skills—and challenges the status quo. It describes a study in which a group of ten-year-olds participated in a taught programme aimed at equipping them with the knowledge and skills to design their own research. This empowering process resulted in the children undertaking research projects of their own choosing, designed, carried out and reported entirely from their perspective. Reports from two of those projects are presented as part of this paper.
