Stability of Delta(9)-tetrahydrocannabinol (THC) in oral fluid using the Quantisal collection device

This article details the stability of Delta(9)-tetrahydrocannabinol (THC) in oral fluid during collection, extraction and storage. Oral fluid is being increasingly used as the specimen of choice for the detection of drug use in various applications. Studies to determine the extraction efficiency of THC from the collection buffer and stability under various laboratory storage conditions were carried out. THC was extracted from the collection pad and buffer with an average efficiency over 80% and was stable in Quantisal oral fluid extraction buffer when stored at refrigerated temperatures. Fluorescent lighting caused THC losses of over 50%, however the presence of the pad reduced the loss. In the dark, the loss of THC at room temperature was approximately 20% over 14 days. When stored with the serum separators in place, THC losses were significant. After 3 days, THC concentration was reduced by almost 30%, and after 14 days, 60% of the drug was lost and the losses were not concentration dependent.     

Interest Rates and Investment in East Asia: An Empirical Evaluation of Various Financial Liberalisation Hypotheses

The article attempts to shed light on the appropriate interest rate policy in the process of economic development. To this end, we examine whether higher interest rates lead to higher investment (and growth) in four East Asian countries. We find that the investment rate went up with real interest rates up to 9 per cent in all four countries but started declining at still higher interest rates in two of the countries. Further, a banking crisis occurred in each of the three countries for which the real interest rates exceeded 9 per cent. This evidence rejects the ‘neo-structuralist’ argument. Nor does it support unbridled financial liberalisation. Yet, it provides only limited support to Stiglitz's case for ‘mild financial repression (real interest rates near zero)’ since reducing real interest rates from say, 6 to 3 or 0 per cent would have reduced investment. The optimum policy seems to be closest to McKinnon's ‘restrained financial liberalisation’ policy, that is, liberalisation with a moderate upper limit (about 6 or 7 per cent) on the real interest rates.     

A cross-cultural study of self-image: Indian,American, Australian,and Irish adolescents

Planning for research and youth welfare programs in every developed and developing country is essential if man envisages the normalization of sick adolescents. Adolescent unit programs are needed in India, as in all parts of the United States, and should be an integral part of medical institutes in every university. Actually, the problem of generation gap, ego identity, and subcultures (i.e., peer group pressure) creating negative attitudes in youth is one of the most explosive problems that behavioral scientists face in the modern era. The present project is an attempt to study the self-image, ego strength, self-esteem, or level of psychological well-being of a normal adolescent group of Indians and to compare this with youth of three other nationalities-American, Irish, and Australian. To measure the self-esteem of an individual, 11 areas of conflict including impulse control, emotional tone, body and self-image, social attitudes, morals, sexual attitudes, family relations, external mastery, vocational and educational goals, psychopathology, and superior adjustment have been examined. The Hindi version of the Offer Self-image Questionnaire has been used. The sample consists of 400 boys and 400 girls, ages 14 to 18, of middle class socioeconomic status; the educational level is high school/intermediate. It is concluded that American and Australian adolescents, in general, have higher self-esteem or ego strength than do Indian and Irish adolescents, respectively.Received her Ph.D. in psychology from the Banaras Hindu University in India. Since 1974 she has been Chairman of the Department of Psychology at Banaras Hindu University. In 1972, she was selected, under the Social Science Exchange program, to spend one year at the Illinois State Psychiatric Institute and the Psychiatric and Psychosomatic Institute of Michael Reese Hospital. Her interests are clinical, social, and psychological aspects of crime and delinquency, and cross-cultural studies of adolescents.     

Unusual chamber marks on plastic shells

Chamber marks alone can serve for identification. It has been observed that these marks are more clearly imprinted on plastic shells fired through homemade crude weapons. The importance of these marks is crucial when other conventional marks are absent. In the present communication, principles of identification are briefly discussed along with the factors affecting the conventional marks. One such actual case is cited.     

Who Gains More from Education? A Comparative Analysis of Business,Farm and Wage Workers in India

The economics literature on returns to education has focused largely on wage workers, thereby ignoring a sizable section of the workforce which is self-employed. This paper presents the estimates of private returns to education for business, farm and wage workers in India using a nationally representative household survey. The paper addresses the sample-selectivity issue arising due to endogenous sector allocation in the earnings equation using the multinomial-selection approach. Our results show that the average rate of return to education is higher for wage workers followed by business and farm workers. Focusing only on wage workers would provide an overestimate of returns by 30 per cent for business workers and by 40–50 per cent for farm workers. Further, the profile of returns across the education ladder varies perceptibly for the three type of workers with higher education being more rewarding for wage workers.     

State Involvement and Forest Co-Governance: Evidence from the Indian Himalayas

This article contributes to the literature on collective action around environmental co-governance by statistically analyzing original data on the experiences of 95 communities in the Indian Himalayas. We compare the performance of co-governance versus indigenous governance institutions, taking into account the causal influence of five classes of independent variables. Our analysis suggests that close involvement of government officials is negatively associated with efforts to manage forests sustainably. We identify contextual conditions that help explain why involvement of state officials has adverse consequences on resource governance outcomes. Our findings are relevant for studies of decentralization policies related to natural resource management that governments are currently pursuing in more than 60 countries.     

EU FTA negotiations with India: The question of liberalisation of public procurement

The proposed bilateral free trade agreement (FTA) between India and the European Union has thrown up many contentious issues among which public procurement is an important one. While India is reluctant to include public procurement in FTA, the European Union (EU) has been insisting that FTA without liberalisation of public procurement is not on the negotiating table. What makes India particularly attractive to the EU is not only the size of its public procurement market but also its rapidly growing economy and demand for infrastructure which presents EU firms with an opportunity to gain market access into this sector under the FTA setting. The EU is insisting on national treatment and non-discrimination as also transparency in Indian procurement system. Indian companies aspire to crack open public procurement market in the EU by entering it through the services sector. However, they are finding EU procedures for ‘data adequacy’ and policies relating to work visa difficult. India’s reluctance to negotiate government procurement under the FTA framework is also attributed partly to administrative costs required for making changes to existing framework and for establishing institutions to implement bilateral obligations. Though several deadlines have been missed, an agreement that could bring mutual benefit for both the EU and India is not out of reach.
