Study of the extra-ionic electron distributions in semi-metallic structures by nuclear quadrupole resonance techniques

A straightforward self-consistent method was developed to estimate solid state electrostatic potentials, fields and field gradients in ionic solids. The method is a direct practical application of basic electrostatics to solid state and also helps in the understanding of the principles of crystal structure. The necessary mathematical equations, derived from first principles, were presented and the systematic computational procedure developed to arrive at the solid state electrostatic field gradients values was given

Nuclear quadrupole resonance studies in semi-metallic structures

Both experimental and theoretical studies are presented on spectrum analysis of nuclear quadrupole resonance of antimony and arsenic tellurides. Numerical solutions for secular equations of the quadrupole interaction energy are also discussed

Effects of public investment in infrastructure on growth and poverty in India

Counter factual policy simulations of sustained increase in public investment in infrastructure, financed through borrowing from commercial banks, shows substantial increase in private investment and thereby output in this sector. Further, due to increase in absorption, real private investment and thereby output in all the other three sectors also seems to increase, which sets-in motion several other macro economic changes. A 20 sustained increase in public investment in infrastructure, which is 0.5 of GDP and 2.7 of total govt. revenue in 2000-03, can accelerate the real macro economic growth by 1.8 in the medium to long-run (6-10 years after the policy change). This will be accompanied by a 1.4 fall in wholesale price index and 0.2 decline in the rate of inflation. Sectoral prices, except that of agriculture, also decline to varying extent, the steepest decline being for infrastructure price. Further, this increase in income will lead to 0.7 reduction in poverty in rural India. This shows the potential for achieving the much-debated 10 aggregate real GDP growth in the Indian economy.

Accounting and Measuring Well-being

The recent literature on the measurement of sustainable income has developed in two important ways for accounting of contribution of natural resource stocks. One set of studies directly addresses the problem of measuring genuine savings or extended wealth formation including changes in human resource capital and natural capital. The second set of studies uses the extended conventional national income accounting methods for accounting of changes in natural resource stocks and environmental extensions of input-output tables. This chapter describes the methodology of measuring genuine savings for a country and reviews the estimates available for different countries. It also suggests a way forward for measuring genuine saving for India

Argument realization in Hindi caregiver-child discourse

An influential claim in the child language literature posits that children use structural cues in the input language to acquire verb meaning (Gleitman, 1990). One such cue is the number of arguments co-occurring with the verb, which provides an indication as to the event type associated with the verb (Fisher, 1995). In some languages however (e.g. Hindi), verb arguments are ellipted relatively freely, subject to certain discourse-pragmatic constraints. In this paper, we address three questions: Is the pervasive argument ellipsis characteristic of adult Hindi also found in Hindi-speaking caregivers’ input ? If so, do children consequently make errors in verb transitivity? How early do children learning a split-ergative language, such as Hindi, exhibit sensitivity to discourse-pragmatic influences on argument realization? We show that there is massive argument ellipsis in caregivers’ input to 3–4 year-olds. However, children acquiring Hindi do not make transitivity errors in their own speech. Nor do they elide arguments randomly. Rather, even at this early age, children appear to be sensitive to discourse-pragmatics in their own spontaneous speech production. These findings in a split-ergative language parallel patterns of argument realization found in children acquiring both nominative-accusative languages (e.g. Korean) and ergative-absolutive languages (e.g. Tzeltal, Inuktitut)

CONCEPTUAL DIFFERENCES BETWEEN THE PACIFIC, ATLANTIC AND ARCTIC TSUNAMI WARNING SYSTEMS FOR CANADA

Canada has coastlines on three of the four oceans on the globe, namely, the Pacific, Atlantic and Arctic oceans. The Pacific and Atlantic oceans are connected to the Arctic Ocean in the north, but still they are three distinct oceans, and need three individual tsunami warning systems. Tsunamis in the Arctic Ocean are not as well documented as in the Pacific and Atlantic oceans. From what is known, tsunamis in the Arctic Ocean are rare and probably are small in amplitude. Because of very low population density, around the Canadian Arctic, at present, there is no priority for a tsunami warning system for Arctic Canada. For the Pacific Ocean, a tsunami warning system is in existence since 1948. In at least one sense, the warning aspects of the tsunami warning system for the Pacific coast of Canada, is relatively simple and straight forward, because it involves only the federal government (PSEPC) and the provincial government of British Columbia (PEP). For the Atlantic Ocean, A tsunami warning system is now being established. The warning aspects will be some what more complex for eastern Canada, since it not only involves the federal government, but also five provinces, namely, Newfoundland and Labrador, Nova Scotia, New Brunswick, Prince Edward Island and Quebec. The Alaska tsunami warning center (ATWC) in Palmer, Alaska, provides tsunami warnings for both Pacific and Atlantic Canada
