Informal finance and rural finance policy in India: historical and contemporary perspectives

From the 1950s up to the early 1990s the All-India data show an ever-declining share of informal credit in the total outstanding debt of rural households. Contemporaneous micro-level studies, using more qualitative research methodologies, provide evidence that questions the strength of this trend, and more recent All-India credit surveys show, first, a levelling, and then a rise, in the share of rural informal credit in 1990/91 and 2000/01, respectively. By reference to findings of a study of village moneylenders in Rajasthan, the paper notes lessons to be drawn. First, informal financial agents have not disappeared from the rural financial landscape in India. Second, formal-sector financial institutions can learn much about rural financial service needs from the financial products and processes of their informal counterparts. Third, a national survey of informal agents, similar to that of the 1921 Census survey of indigenous bankers and moneylenders, would provide valuable pointers towards policy options for the sector. A recent Reserve Bank of India Report on Moneylender Legislation not only explores incentive mechanisms to better ensure fair practice, but also proposes provision for a new category of loan providers that would explicitly link the rural informal and formal financial sectors.

Effects of trauma exposure on the cortisol response to dexamethasone administration in PTSD and major depressive disorder

Objective: To evaluate cortisol suppression following 0.5 mg of dexamethasone (DEX) in trauma survivors (N = 52),with posttraumatic stress disorder (PTSD), major depressive disorder (MDD), both, or neither disorder, and in subjects never exposed to trauma (N = 10), in order to examine interactions between diagnosis and trauma history on cortisol negative feedback inhibition. Method: Lifetime trauma exposure and psychiatric diagnoses were assessed and blood samples were obtained at 8:00 a.m. for the determination of baseline cortisol. Participants ingested 0.5 mg of DEX at 11:00 p.m. and blood samples for determination of cortisol and DEX were obtained at 8:00 a.m. the following day. Results: PTSD was associated with enhanced cortisol suppression in response to DEX Among trauma survivors, the presence of a traumatic event prior to the "focal" trauma had a substantial impact on cortisol suppression in subjects with MDD. Such subjects were more likely to show cortisol alterations similar to those associated with PTSD, whereas subjects with MDD with no prior trauma were more likely to show alterations in the opposite direction, i.e. relative non-suppression. Conclusions: Cortisol hypersuppression in PTSD appears not to be dependent on the presence of traumatic events prior to the focal trauma. However, prior trauma exposure may affect cortisol suppression in MDD. This finding may have implications for understanding why only some depressed patients show non-suppression on the DST.

Effect on components of the intestinal microflora and plasma neuropeptide levels of feeding Lactobacillus delbrueckii, Bifidobacterium lactis, and inulin to adult and elderly rats

The aim of this study was to compare the effects of the mixture of Lactobacillus delbrueckii subsp. rhamnosus strain GG, Bifidobacterium lactis Bb12, and inulin on intestinal populations of lactobacilli, bifidobacteria, and enterobacteria in adult and elderly rats fed the same (in quality and quantity) diet. The portal plasma levels of two neuropeptides, neuropeptide Y (NPY) and peptide YY (PYY), were also evaluated to assess the physiological consequences of the synbiotic treatment for the gastrointestinal (GI) tracts of rats of different ages. Adult (n = 24) and elderly (n = 24) male rats were fed the AIN-93 M maintenance diet. After 2 weeks of adaptation, the diet of 12 rats of each age group was supplemented with 8% inulin and with strains GG and Bb12 to provide 2.2 x 10(9) CFU of each strain g(-1) of the diet. Blood and different regions of the GI tract were sampled from all rats after 21 days of the treatment. Treatment with the mixture of strain GG, strain BB12, and inulin induced significantly different changes in the numbers of lactobacilli, bifidobacteria, and enterobacteria of the stomach, small intestine, cecum, and colon microflora. Moreover, the GG, BB12, and inulin mixture increased the concentrations of NPY and PYY for adult rats. For the elderly animals, the PYY concentration was not changed, while the NPY concentration was decreased by treatment with the GG, BB12, and inulin mixture. The results of the present study indicate that the physiological status of the GI tract, and not just diet, has a major role in the regulation of important groups of the GI bacteria community, since even the outcome of the dietary modification with synbiotics depends on the ages of the animals.

Proposed feasibility oversight for pre-pack administration in England and Wales: window dressing or effective reform?

The 2014 Graham proposals aimed at reducing recidivism are unlikely to achieve the desired goals. It is argued that due consideration must be had for the future of the rescued entity. Further, both the viability review and the proposed capital structure of the rescued entity must be carefully assessed.

Effects of chronic stress on nicotine-induced locomotor activity and corticosterone release in adult and adolescent rats

We examined nicotine-induced locomotion and increase in corticosterone plasma levels in adolescent and adult animals exposed to chronic restraint stress. Adolescent [postnatal day (P) 28-37] and adult (P60-67) rats were restrained for 2 hours once daily for 7 days. Three days after the last exposure to stress, the animals were challenged with saline or nicotine (0.4 mg/kg subcutaneously). Nicotine-induced locomotion was recorded in an activity cage. Trunk blood samples were collected in a subset of adolescent and adult rats and plasma corticosterone levels were determined by radioimmunoassay. Exposure to stress did not affect the nicotine-induced locomotor- or corticosterone-activating effects in both ages.
