Development strategy in Bihar through revitalizing the agricultural sector : a preliminary analysis

Based mainly on secondary data and partly on primary information obtained through field surveys in selected rural areas in Bihar in 2011, this paper firstly argues the critical importance of agricultural growth for overall economic development, and then reviews the sluggish growth of agriculture in Bihar in the past and examines the major reasons for this. The long-term negligence of agricultural research (especially development and diffusion endeavors for improved rice varieties suitable to the local conditions of Bihar) by the state government and some sort of ‘backwardness’ in tube-well irrigation technology can be pointed out as important constraints. There is, in particular, the ‘paradox’ in Bihar agriculture of why rice and wheat yields have remained so low in spite of the relatively well-developed irrigation by tube-wells. Finally, by showing the process of a rapid increase in autumn and winter rice yields during the 1990s in West Bengal, it is suggested that Bihar farmers and policy-makers should learn from the experience of West Bengal in order to get some hints for the development of the rice sector in Bihar

Rich Periphery, Poor Center: Myanmar's Rural Economy under Partial Transition to a Market Economy

This paper looks at the case of Myanmar in order to investigate the behavior and welfare of rural households in an economy under transition from a planned to a market system. Myanmar's case is particularly interesting because of the country's unique attempt to preserve a policy of intervention in land transactions and marketing institutions. A sample household survey that we conducted in 2001, covering more than 500 households in eight villages with diverse agro-ecological environments, revealed two paradoxes. First, income levels are higher in villages far from the center than in villages located in regions under the tight control of the central authorities. Second, farmers and villages that emphasize a paddy-based, irrigated cropping system have lower farming incomes than those that do not. The reason for these paradoxes are the distortions created by agricultural policies that restrict land use and the marketing of agricultural produce. Because of these distortions, the transition to a market economy in Myanmar since the late 1980s is only a partial one. The partial transition, which initially led to an increase in output and income from agriculture, revealed its limit in the survey period.

Agricultural Policies and Development of Myanmar\u27s Agricultural Sector: An Overview

This paper reviews the development of the agricultural sector in Myanmar after the transition to an open economy in 1988 and analyzes the nature as well as the performance of the agricultural sector. The avoidance of social unrest and the maintenance of control by the regime are identified as the two key factors that have determined the nature of agricultural policy after 1988. A major consequence of agricultural policy has been a clear difference in development paths among the major crops. Production of crops that had a potential for development showed sluggish growth due to policy constraints, whereas there has been a self-sustaining increase in the output of those crops that have fallen outside the remit of agricultural policy

Myanmar migrant laborers in Ranong, Thailand

Thailand is the major destination for migrants in mainland Southeast Asia, and Myanmar (Burmese) migrants account for the dominant share. This paper sheds light on the actual working conditions and the life of Myanmar migrants in Thailand, based on our intensive survey in Ranong in southern Thailand in 2009. We found a wide range of serious problems that Myanmar migrants face in everyday life: very harsh working conditions, low income, heavy indebtedness, risk of being human-trafficking victims, harassment by the police and military (especially of sex workers), high risk of illness including malaria and HIV/AIDS and limited access to affordable medical facilities, and a poor educational environment for their children.Myanmar, Thailand, Migrant labor, Migration, Household

Ether stress-induced Alzheimer-like tau phosphorylation in the normal mouse brain

AbstractTau is reversibly hyperphosphorylated in the mouse brain by starvation or cold water swimming. Here, we report tau phosphorylation in the hippocampus of normal mouse after ether anesthesia, known to trigger typical stress reactions. Robust phosphorylation of tau was observed immediately and 10min after ether vapor exposure at Ser202/Thr205 and Thr231/Ser235, sites typically phosphorylated in Alzheimer brains. The phosphorylation levels returned to baseline by 1h. The most conspicuous and consistent change in the protein kinases studied was the inactivating phosphorylation of Ser9 of TPKI/GSK3β in close correspondence with tau phosphorylation. These findings show that tau phosphorylation is a rapid physiological process integral to stress response system, and suggest involvement therein of TPKI/GSK3β

Reaction-Diffusion Pattern in Shoot Apical Meristem of Plants

A fundamental question in developmental biology is how spatial patterns are self-organized from homogeneous structures. In 1952, Turing proposed the reaction-diffusion model in order to explain this issue. Experimental evidence of reaction-diffusion patterns in living organisms was first provided by the pigmentation pattern on the skin of fishes in 1995. However, whether or not this mechanism plays an essential role in developmental events of living organisms remains elusive. Here we show that a reaction-diffusion model can successfully explain the shoot apical meristem (SAM) development of plants. SAM of plants resides in the top of each shoot and consists of a central zone (CZ) and a surrounding peripheral zone (PZ). SAM contains stem cells and continuously produces new organs throughout the lifespan. Molecular genetic studies using Arabidopsis thaliana revealed that the formation and maintenance of the SAM are essentially regulated by the feedback interaction between WUSHCEL (WUS) and CLAVATA (CLV). We developed a mathematical model of the SAM based on a reaction-diffusion dynamics of the WUS-CLV interaction, incorporating cell division and the spatial restriction of the dynamics. Our model explains the various SAM patterns observed in plants, for example, homeostatic control of SAM size in the wild type, enlarged or fasciated SAM in clv mutants, and initiation of ectopic secondary meristems from an initial flattened SAM in wus mutant. In addition, the model is supported by comparing its prediction with the expression pattern of WUS in the wus mutant. Furthermore, the model can account for many experimental results including reorganization processes caused by the CZ ablation and by incision through the meristem center. We thus conclude that the reaction-diffusion dynamics is probably indispensable for the SAM development of plants

Confocal microphotoluminescence of InGaN-based light-emitting diodes

Spatially resolved photoluminescence (PL) of InGaN/GaN/AlGaN-based quantum-well-structured light-emitting diodes (LEDs) with a yellow-green light (530 nm) and an amber light (600 nm) was measured by using confocal microscopy. Submicron-scale spatial inhomogeneities of both PL intensities and spectra were found in confocal micro-PL images. We also found clear correlations between PL intensities and peak wavelength for both LEDs. Such correlations for yellow-green and amber LEDs were different from the reported correlations for blue or green LEDs. This discrepancy should be due to different diffusion, localization, and recombination dynamics of electron-hole pairs generated in InGaN active layers, and should be a very important property for influencing the optical properties of LEDs. In order to explain the results, we proposed a possible carrier dynamics model based on the carrier localization and partial reduction of the quantum confinement Stark effect depending on an indium composition in InGaN active layers. By using this model, we also considered the origin of the reduction of the emission efficiencies with a longer emission wavelength of InGaN LEDs with high indium composition

It was not a fall, but fainting: A case report of pulmonary embolism

We encountered a case of pulmonary thromboembolism, in which an 84-year-old woman (body weight 62 kg, height 150 cm) fell in the ward eight days after upper arm surgery. In this event, she had fractured her ankle and hit her head, with transient loss of consciousness. She needed surgery for the ankle fracture under general anesthesia. Her anesthesia course was unstable, with heart rate varying between 95 and 140 bpm, systolic blood pressure between 70 and 110 mmHg, and oxygen saturation between 92 and 98%. Immediately after reversing anesthesia, we performed bedside ultrasound and diagnosed acute pulmonary embolism in the operating room. We assume that the event was not a simple fall, but pulmonary embolism-related fainting (syncope). This case and recent reports provide two lessons: (1) cases of syncope among postoperative patients may be reported as simple falls in the safety surveillance of hospitals, and (2) ultrasonography at the bedside plays a pivotal role in the diagnosis of pulmonary embolism in perioperative settings
