Dimensions of Economic Mobility in Kerala’s Migrant Households

This paper analyses economic mobility as an evaluating criteria in gauging the nature and extent of improvement in economic position of households having migrants in terms of remittances and extent of economic mobility. Using panel data from Kerala Migration Surveys, we estimate the quantum of improvement in standards of living of migrant households in Kerala through transition matrices and statistical and econometric techniques

Decomposition and Progression of Urbanisation in India

This study, using data from the Census of India for 2001 and 2011, decomposes urbanisation ratio into its mathematical components to explain the causes of changes in this ratio over time. Using statistical techniques, we adjust current urbanisation levels of major states in India according to the progression of towns to larger sizes and estimate Class Progression Indices to arrive at a meaningful discussion on the spread of urbanisation

Measuring quality in Indian VET institutions: development steps towards a framework adapted to the national context

Purpose: The quality of vocational education and training (VET) processes plays an important role in international education policies and research. In India, issues of quality came into focus in recent years due to an increased demand for skilled workers, and continuing challenges in the area of quality of VET. Existing quality assurance mechanisms of VET in India are characterised by a lack of comprehensiveness and uniform standards. This paper addresses the contextualised development of an Indian-specific approach for quality measurement. It centres on following research question: Which quality areas, criteria and related indicators are of relevance for measuring quality comprehensively? Approach: Design-based research substantiates the research objective, which is to develop a model that is theoretically and technically sound, as well as adapted to the national context. The question of how to create "cultural-fit" was essential for the research process illustrated in this paper. Starting point for the development of the approach was to build a structured review, and following analysis, with reference to existing models and approaches to quality management. The initial search examined national and international academic sources for quality management in business and education, as well as governmental sources for quality management strategies in VET. A significant number of models were selected, based on inclusion criteria, and these models were aggregated to provide a source for a first own conception of an approach. Results: Quality dimensions and criteria were collected and identified with reference to distribution across models. In total, seven major quality areas are identified, namely Institutional Sphere and Context; Personnel; Educational Planning, Provision and Assessment; Learning and Teaching; Leadership and School Management; Industry Linkage and Learner Achievements. In addition, 40 quality criteria are determined under these major quality fields, and relevant quantitative and qualitative sub-indicators for measurement are derived. Conclusion: The actual results will be a basis for the following pilot-based implementation in India. The model can provide meaningful feedback and data-based recommendations for continuous improvement of the Indian VET system and may furthermore provide for a reflected and contextually adapted implementation in other countries.

Dynamic Movement of the Calcium Sensor STIM1 and the Calcium Channel Orai1 in Activated T-Cells: Puncta and Distal Caps

The proteins STIM1 and Orai1 are the long sought components of the store-operated channels required in T-cell activation. However, little is known about the interaction of these proteins in T-cells after engagement of the T-cell receptor. We found that T-cell receptor engagement caused STIM1 and Orai1 to colocalize in puncta near the site of stimulation and accumulate in a dense structure on the opposite side of the T-cell. FRET measurements showed a close interaction between STIM1 and Orai1 both in the puncta and in the dense cap-like structure. The formation of cap-like structures did not entail rearrangement of the entire endoplasmic reticulum. Cap formation depended on TCR engagement and tyrosine phosphorylation, but not on channel activity or Ca2+ influx. These caps were very dynamic in T-cells activated by contact with superantigen pulsed B-cells and could move from the distal pole to an existing or a newly forming immunological synapse. One function of this cap may be to provide preassembled Ca2+ channel components to existing and newly forming immunological synapses
