Over the past two decades, the topic of nation brands has attracted the interest of academics, researchers, and policy markers alike. Governments in particular have used the concept of nation brands to attract support from international audiences. This study developed a conceptual framework of donation behaviour with nation brand perceptions as a mediating variable between donation motives and donation behaviour. The framework proposes that people‘s perception of a nation‘s brand will have significant implications on the willingness and extent of contribution to a charitable cause associated with the nation.

Background There are ongoing questions about whether unemployment has causal effects on suicide as this relationship may be confounded by past experiences of mental illness. The present review quantified the effects of adjustment for mental health on the relationship between unemployment and suicide. Findings were used to develop and interpret likely causal models of unemployment, mental health and suicide. Method A random-effects meta-analysis was conducted on five population-based cohort studies where temporal relationships could be clearly ascertained. Results Results of the meta-analysis showed that unemployment was associated with a significantly higher relative risk (RR) of suicide before adjustment for prior mental health [RR 1.58, 95% confidence interval (CI) 1.33–1.83]. After controlling for mental health, the RR of suicide following unemployment was reduced by approximately 37% (RR 1.15, 95% CI 1.00–1.30). Greater exposure to unemployment was associated with higher RR of suicide, and the pooled RR was higher for males than for females. Conclusions Plausible interpretations of likely pathways between unemployment and suicide are complex and difficult to validate given the poor delineation of associations over time and analytic rationale for confounder adjustment evident in the revised literature. Future research would be strengthened by explicit articulation of temporal relationships and causal assumptions. This would be complemented by longitudinal study designs suitable to assess potential confounders, mediators and effect modifiers influencing the relationship between unemployment and suicide.

Australian school curricula are currently being reformed with the nation-wide introduction of the Australian Curriculum, designed to bring national subject content and assessment standard conformity through the detailing of the “core knowledge, understanding, skills and general capabilities [that are deemed] important for all Australian students” (Australian Curriculum, Assessment and Reporting Authority [ACARA], 2008). The reform and implementation of any curriculum requires well- structured planning, and at the school level, curriculum implementation requires the input of teachers – the frontline stakeholders. Research suggests that the implementation of a new curriculum requires concentrated support to ensure that teachers are able to work and progress through professional learning effectively (Mulford, 2008; Australian Curriculum Coalition, 2010). This chapter is presented in two parts: a discussion about the incoming Australian Curriculum: English, and an outline of a proposed qualitative case study that will examine English teachers’ perceptions of the implementation of the Australian Curriculum: English in Tasmania.

Moral norms and anticipated regret are widely used extensions to the theory of planned behaviour, yet there is some evidence to suggest that these constructs may conceptually overlap as predictors of intention. Two health-related behaviours with distinct moral implications (Study 1: organ donation registration, N = 352 and Study 2: condom usage, N = 1815) were therefore examined to ascertain whether moral norms and anticipated regret are indeed conceptually distinct. While evidence consistent with conceptual overlap was identified in Study 1, the evidence for such overlap in Study 2 was more ambiguous. In Study 3, a meta-analysis of existing literature revealed that the relationship between moral norms and anticipated regret was moderated by the extent of the moral implications arising from the behaviour under examination. Taken together, these findings suggest that conceptual overlap between moral norms and anticipated regret is more likely to occur among behaviours with obvious moral implications. Researchers wishing to examine the predictive utility of moral norms and anticipated regret among such behaviours would therefore be advised to aggregate these measures to form a composite variable (personal norms).

A growing body of literature has focused on an alleged “power shift” from the United States to China (and from the West to the East more generally). For all its complexities and nuances, much of this power-shift literature continues to unreflectively hold onto a conventional way of conceptualizing power as a type of quantitatively measurable and zero-sum property possessed by the state.  Without critically engaging with the conceptual question of what power means, however, the power-shift debate is both inadequate and misleading. Drawing on some alternative ways of conceptualizing power, I aim to illustrate the contingent and socially constructed nature of “Chinese” economic power and, in doing so, problematize the widely held view of a US-China power shift. I contend that insofar as power is socially constructed, how it is conceptualized matters for international relations. The need to rethink power is at the core of building a new type of major power relationship.

 This report summarizes material testing on three metals used in the Numisheet 2014 Benchmark Study, a DP 600 steel sheet, a TRIP 780 steel sheet, and an aluminum alloy 5182-O sheet. The tests include r value, yield stress, and hardening in uniaxial tension at 15 degree increments of the loading axis in the plane of the sheet, r value, yield stress, and hardening in equal biaxial tension, and forming limit curves for all three metals. In addition, cyclic tension-compression tests along the rolling direction are reported for the DP 600 and aluminum alloy.

Synchrotron infrared (IR) and micro-Raman spectra of natrolites containing alkaline-earth ions (Ca2+, Sr2+, and Ba2+) and heavy metals (Cd2+, Pb2+, and Ag+) as extra-framework cations (EFCs) were measured under ambient conditions. Complementing our previous spectroscopic investigations of natrolites with monovalent alkali metal (Li+, Na+, K+, Rb +, and Cs+) EFCs, we establish a correlation between the redshifts of the frequencies of the 4-ring and helical 8-ring units and the size of the EFCs in natrolite. Through ab initio calculations we have derived structural models of Ca2+- and Ag+-exchanged natrolites with hydrogen atoms, and found that the frequency shifts in the H - O - H bending mode and the differences in the O - H stretching vibration modes can be correlated with the orientations of the water molecules along the natrolite channel. Assuming that the members of a solid solution series behave as an ideal mixture, we will be able to use spectroscopy to probe compositions. Deviation from ideal behavior might indicate the occurrence of phase separation on various length scales. Copyright © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

A tourism consumption system (TCS) is defined as the setof related travel thoughts, decisions, and behaviors by a discretionarytraveler prior to, during, and following a trip. Thecentral proposition of a theory of TCS is that the thoughts,decisions, and behaviors regarding one activity influence thethoughts, decisions, and behaviors for a number of other activities.Using exit interview travel data and quick clusteringanalysis, this article empirically examines seven basic TCSpropositions pertaining to decisions made once the destinationhas been selected. The findings support and extend thebasic propositions specifically indicating clear patterns inthe behaviors of visitors to Prince Edward Island, Canada.The authors conclude by recommending that this approach isuseful for tourism marketers and practitioners in general.Suggestions are provided for analyzing TCS to increase theeffectiveness of tourism marketing strategies.
