Diamond pricing and valuation in South Africa’s extractive political economy

, 2016
This article explores the valuation and marketisation of diamonds in South Africa from 2004 to 2012. It argues that there is no positivist foundation for a ‘real’ or ‘fair’ price from which derogations can be measured, which constitutes a challenge for ...

Environmental Statecraft, Fragmented Authoritarianism, and Technocratic Governance: The Structure and Agency of China's Local Environmental Politics

Environmental Policy and Governance, EarlyView.
ABSTRACT Local environmental politics in China is often said to be dominated by state‐controlled modes of multi‐level governance. However, top‐down governance is embedded within and transformed by local politics, adding complexity to governance practices and environmental outcomes.

A Reassessment of Petrochemistry of ~1.2 Ga Tonalitic Rocks of the Northern Tugela Terrane, Natal Metamorphic Belt, South Africa: Further Constraints on the Evolution of This Belt

Geological Journal, EarlyView.
Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.

Cultural Strength Mechanisms: Family Ethnic Socialization, Ethnic Identity, Familism Links to Rural US Latino/a Youth Prosocial Behaviors Across Time

Journal of Adolescence, EarlyView.
ABSTRACT Introduction Cultural strength‐based models propose that family ethnic socialization promotes prosocial development in Latino/a youth through cultural values such as ethnic identity and familism. However, longitudinal research testing these serial pathways remains scarce, and prosocial behavior is understudied in rural, emerging immigrant ...
