The determinants and interrelationship of carbon emissions and economic growth in African economies: Fresh insights from static and dynamic models

This study explores the interrelationship between CO₂ emissions and economic growth in selected Africa economies from 1990 to 2014 providing evidence from both static and dynamic models. Results show that increases in energy use have a significant and positive effect on economic growth; which goes to show that growth in Africa is actually energy dependent. Further findings suggest that CO₂ emissions have no significant contemporaneous effect, however, a significant and negative effect at a one‐period lag on economic growth. The significance of the impacts is consistently confirmed by both the static and dynamic estimations. Also, trade adds to economic growth and also contributes to environmental deterioration in Africa. There is a dire need for Africa to adjust its energy portfolio by shifting to clean energy sources which will enhance sustainable economic growth without deteriorating the environment.     

Persistence and polarisation: A study in the dynamics of agrarian contradiction

Backward agrarian economies like that of contemporary Bangladesh are generally held to be strongly subject to a process of polarisation between those with increasing ownership of land and those who become landless with nothing but their labour‐power to sell. Empirical evidence has often been at variance with such unilinear prognosis. Using data from south‐eastern Bangladesh, this study examines the complexity of the dynamics of backward agriculture. It is shown that the very process of polarisation itself generates a contradictory process of stabilisation of the small peasantry through the creation of supplementary income opportunities. It is the resultant dynamic which often manifests itself in the persistence of a large number of small‐owner farms amidst the process of polarisation.     

Introduction to Lavigne: Money and Socialism

In a continuation of his earlier work on the history and structure of psychiatry and psychoanalysis Bercherie examines Frued's views on epistemology and then identifies the presence of four metapsychological models in his writings. The models are then related to the four major currents in post-Freudian psychoanalysis: Kleinian analysis, ego-psychology, Lacanianism and the more diffuse ‘marginal’ current. He ends by expressing the hope that the prevailing climate of theoretical dogmatism will give way to a new spirit of synthesis and tolerance which will lead to major developments in both the theory and the practice of psychoanalysis.     

Factors influencing working conditions of small enterprises in Sylhet City,Bangladesh

This article looks at variables that affect the working lives of small business entrepreneurs in Sylhet City, Bangladesh, and whether microfinance ensures decent working conditions in small ventures. The findings show that social dialogue among borrowers and their enterprise stability have the largest impacts on work and non-work life, and that social discussions among borrowers have the most significance in achieving harmony between work and non-work life. The results suggest that loan organisations need to draw in their borrowers more by using social relations in empowering decent working conditions.     

The economy and the educational system in capitalistic societies

The purpose of this article is to analyse the relations between the educational system and economy in capitalist societies. The economy is conceived here in terms of its technical as well as its social relations. The analysis here is centered around the capitalist labour market rather than capitalist technical relations of production as is usual in the literature on the relations between the educational system and the economy. This article is a preliminary attempt to break out of both economistic and sociologistic conceptions which dominate the literature on education.     

Land reforms in Pakistan: A reconsideration

Abstract

Before the introduction of the high yielding varieties of food grain in the late 1960s the argument for land reform was a simple one. It was observed that small farms had a higher yield per acre than large farms, so it was argued that a re-distribution of owned land in favor of the smaller farmers would improve average yields in agriculture. Hence land reforms were considered advisable both on grounds that they would reduce the degree of inequality of rural incomes, as well as on grounds of efficiency. The efficiency argument for land reforms in Pakistan gathered momentum in the 1950s when agricultural stagnation began to fetter the growth of industry. Agriculture provided not only food grains for the rising urban population but also provided most of the foreign exchange with which industrial machinery and raw materials were imported. Accordingly, slow agricultural growth generated both a crisis in the balance of payments as well as food shortages in the urban sector. In such a situation even the technocrats who were merely interested in the growth of GNP joined the cry of the social reformers for a land reform. It began to be seen as a necessary instrument for accelerating agricultural growth and thereby releasing the constraint on industrial growth.     

Determination of methadone in urine using ion trap GC/MS in positive ion chemical ionization mode

Methadone is a potent analgesic and sedative. It is widely used in the treatment of heroin addiction and is often encountered in forensic specimens. In electron impact (EI) gas chromatography/mass spectrometry (GC/MS) mode, methadone produces predominantly a m/z 72 ion, which is not sufficiently characteristic for identification. Determination of the molecular ion, which can be achieved using chemical ionization (CI) provides diagnostic information and better identification of the drug. This paper describes the development of a positive ion CI GC/MS procedure, using a liquid reagent gas and ion trap instrumentation, for the determination of methadone and its metabolites in urine. CI generally produces a single molecular ion spectrum, but optimization of the reagent gas parameters increases the fragmentation of the molecule, allowing determination of ion ratios if required. The procedure is sensitive, diagnostic and is currently in routine use in our laboratory.
