Student-Parent attitudes towards Filipino migrant teachers in Indonesia

Using ethnographic data gleaned from a foreign managed Christian school in Indonesia, this article situates the ethnic prejudices of Indonesian Chinese parents and students towards Filipino teachers within the organizational and cultural politics of private schooling. It is argued that the commoditization of education as a form of market consumption alongside the masculinized international curriculum help shape the feminization of teachers from the Philippines. Catering to the aspirations of the country’s minority ethnic Chinese, privately managed schools actively recruit trained teachers from the Philippines, many of whom are female and are perceived by students and their parents as exhibiting negative symbolic capital. In the process of their employment, they encounter occasional moments of less than complete success and challenges in their jobs. This article situates this prejudice within the cultural politics of masculinized Chinese schooling in Indonesia, while seeking to shed light on the role of Filipino work migrancy in Indonesia’s formal employment sector

Nothing Lasts Forever: Environmental Discourses on the Collapse of Past Societies

The study of the collapse of past societies raises many questions for the theory and practice of archaeology. Interest in collapse extends as well into the natural sciences and environmental and sustainability policy. Despite a range of approaches to collapse, the predominant paradigm is environmental collapse, which I argue obscures recognition of the dynamic role of social processes that lie at the heart of human communities. These environmental discourses, together with confusion over terminology and the concepts of collapse, have created widespread aporia about collapse and resulted in the creation of mixed messages about complex historical and social processes

Facilitation at single synapses probed with optical quantal analysis

Many synapses can change their strength rapidly in a use-dependent manner, but the mechanisms of such short-term plasticity remain unknown. To understand these mechanisms, measurements of neurotransmitter release at single synapses are required. We probed transmitter release by imaging transient increases in [Ca2+] mediated by synaptic N-methyl-D-aspartate receptors (NMDARs) in individual dendritic spines of CA1 pyramidal neurons in rat brain slices, enabling quantal analysis at single synapses. We found that changes in release probability, produced by paired-pulse facilitation (PPF) or by manipulation of presynaptic adenosine receptors, were associated with changes in glutamate concentration in the synaptic cleft, indicating that single synapses can release a variable amount of glutamate per action potential. The relationship between release probability and response size is consistent with a binomial model of vesicle release with several (>5) independent release sites per active zone, suggesting that multivesicular release contributes to facilitation at these synapses
