Energy Levels and Radiative Rates for Transitions in F-like Sc~XIII and Ne-like Sc~XII and Y~XXX

Energy levels, radiative rates and lifetimes are reported for F-like Sc~XIII and Ne-like Sc~XII and Y~XXX for which the general-purpose relativistic atomic structure package ({\sc grasp}) has been adopted. For all three ions limited data exist in the literature but comparisons have been made wherever possible to assess the accuracy of the calculations. In the present work the lowest 102, 125 and 139 levels have been considered for the respective ions. Additionally, calculations have also been performed with the flexible atomic code ({\sc fac}) to (particularly) confirm the accuracy of energy levels.Comment: 24pp of Text including 12 Tables will appear in Atoms 6 (2018

Discrepancies in Atomic Data and Suggestions for their Resolutions

The analysis and modelling of a range of plasmas (for example: astrophysical, laser-produced and fusion), require atomic data for a number of parameters, such as energy levels, radiative rates and electron impact excitation rates, or equivalently the effective collision strengths. Such data are desired for a wide range of elements and their many ions, although all elements are not useful for all types of plasmas. Since measurements of atomic data are mostly confined to only a few energy levels of some ions, calculations for all parameters are highly important. However, often there are large discrepancies among different calculations for almost all parameters, which makes it difficult to apply the data with confidence. Many such discrepancies (and the possible remedies) were discussed earlier (Fusion Sci. Tech. 2013, 63, 363). Since then a lot more anomalies for almost all of these atomic parameters have come to notice. Therefore, this paper is a revisit of various atomic parameters to highlight the large discrepancies, their possible sources and some suggestions to avoid those, so that comparatively more accurate and reliable atomic data may be available in the future.Comment: 18 pages of text including 7 figures will appear in Atoms 5 (2017

Impact of Special Economic Zones on Employment, Poverty and Human Development

This study aims at examining the impact of Special Economic Zones (SEZs) on human development and poverty reduction in India. It identifies three channels through which SEZs address these issues: employment generation, skill formation (human capital development), and technology and knowledge upgradation. It examines how the impact of SEZs is passed through each of these channels. The study finds that the modality differs significantly according to the characteristics of the SEZs, in particular, the level of their development as reflected in the composition of economic activities. Within this framework, the study examines the sectoral and economic composition of SEZ activities in India. It finds that labour intensive, skill intensive and technology intensive firms co exist in India's zones and, therefore argues that all the three effects described above are likely to be important in the Indian context. Empirical findings reported in the study are based on the data collected from both secondary sources and primary surveys. The primary survey based data was generated through extensive interviews of entrepreneurs and workers across the three largest SEZs (in terms of their contribution to exports and employment) : SEEPZ, Madras and Noida. The analysis reveals that `employment generation' has been the most important channel through which SEZs lend themselves to human development concerns, in India. Employment generated by zones is remunerative. Wage rates are not lower than those prevailing outside the zones. Besides, working conditions, non monetary benefits (such as transport, health and food facilities), incentive packages and social security systems are better than those prevailing outside the zones, in particular, in the small/informal sector. The role of SEZs in human capital formation and technology upgradation is found to be rather limited. The study argues that the zones' potential could not be exploited fully in India. This could primarily be attributed to the limited success of SEZs in attracting investment and promoting exports. The new SEZ policy gives a major thrust to SEZs. However the creation of SEZs alone does not ensure the realization of their potential. The government will need to play a more proactive role for effective realization of the full range of benefits from SEZs.Special Economic Zones, Human Development, Employment, Poverty, Skill Formation, Technology Transfers, Local R&D
