Slab breakoff： a causal mechanism or pure convenience？

The idea of lithosphere delamination has long been conceived as a mechanism to cause tectonic uplift,metamorphism and magmatism in active orogenic belts[1–3].Since the publication of the two seminal papers by Davies and von Blanckenburg[4,5],the idea of slab breakoff has been more widely accepted over the last$20 years as the favored mechanism to cause collision zone mag-

KMAP-O framework for care management research of patients with type 2 diabetes

AIM To review impacts of interventions involving self-management education, health coaching, and motivational interviewing for type 2 diabetes. METHODS A thorough review of the scientific literature on diabetes care and management was executed by a research team. RESULTS This article summarizes important findings in regard to the validity of developing a comprehensive behavioral system as a framework for empirical investigation. The behavioral system framework consists of patients' knowledge(K), motivation(M), attitude(A), and practice(P) as predictor variables for diabetes care outcomes(O). Care management strategies or health education programs serve as the intervention variable that directly influences K, M, A, and P and then indirectly affects the variability in patient care outcomes of patients with type 2 diabetes. CONCLUSION This review contributes to the understanding of the KMAP-O framework and how it can guide the care management of patients with type 2 diabetes. It will allow the tailoring of interventions to be more effective through knowledge enhancement, increased motivation, attitudinal changes, and improved preventive practice to reduce the progression of type 2 diabetes and comorbidities. Furthermore, the use of health information technology for enhancing changes in KMAP and communications is advocated in health promotion and development.

Do credit constraints affect households'economic vulnerability?Empirical evidence from rural China

Poverty alleviation is still one of the major challenges in developing countries,especially in transitional economy like China.From the perspective of anti-poverty,this paper examines the impact of formal credit constraints(FCCs)and informal credit constraints(IFCCs)on economic vulnerability(EV)using the data from the China Household Income Project(CHIP)survey for 2013(CHIPs 2013)of rural households.The potential endogeneity problem of credit constraints(CCs)is addressed by applying the control function approach within an ordered probit model.The results show that both FCCs and IFCCs have a robust positive and significant impact on the EV of rural households and that the impact of FCCs is greater than that of IFCCs.To identify the potential mechanisms through which CCs affect EV,the seemingly unrelated regressions are used and the potential intercorrelation among these mechanisms is examined.We find that the impact of CCs on EV is partly mediated by health,trust,per capita financial assets and per capita income,whereby health and per capita income contribute to most of the total indirect effect.Thus,policies focus on supply-side and demand-side to improve credit accessibility could reduce rural households'EV,especially through its positive effect on health and per capita income.
