Wheat Marketing and its Efficiency in India

The study examines the marketing of wheat in India, focusing on the private marketing system, the marketing efficiency and quality. Wheat is now a major food staple in India, crucial to India’s food economy and security. With production reaching 70 to 75 million tons and a large demand, India’s wheat economy is the second largest in the world. The efficiency of marketing is crucial to farmer incomes, consumer welfare, as well as government budgets and the economy. Substantial changes are taking place in the marketing of wheat. The study finds that the farmers now almost invariably sell in the nearby primary markets rather than to village traders. The farmer choice of varieties is now becoming market oriented with quality and market acceptance becoming as important as yield. The typically market intermediary provides hardly any special, value adding or developmental services in return for the commissions and margins. The farmers see considerable scope for improvement in the marketing system. The consumer demand for wheat varies considerably across the country. But wheat has made inroads into food consumption in the east and the south. The retailers are increasingly conscious of consumer demand and quality, and keep a varietiy of wheat and wheat products. Direct buying of wheat grain, storing, and own recourse to processing are common in the north and the west, whereas direct purchase of wheat products such as flour is the norm in the east and the south. The trend is towards direct purchase of processed wheat products, and within this from loose to packaged branded wheat products. The estimated average total marketing cost of wheat is found to be of the order of Rs. 266 per quintal, and in this transport has the largest share of 40 percent, commission and taxes make up 25 percent, and wastage another 15 percent. When compared to the consumer-farmer price spread, the marketing costs account for 74 percent of the spread, leaving 26 percent for margins – this is fairly efficient but there is significant scope for improvement. On an average, the farmers receive 66 percent of what the consumer pays. The government channel marketing cost is reported to be Rs. 309 per quintal, but this does not cover the whole chain and is not strictly comparable. Examination of the question of market integration for wheat is difficult due to data and quality difference problems. Co-integration analysis using monthly price data for eight markets for the period April 1997 to June 2004 indicates that nationally the markets are integrated but the LOP (Law of One Price) does not hold, and the presence of six common stochastic trends implies the absence of full pair-wise co-integration.

Eating the elephant whole or in slices: views of participants in a smoking cessation intervention trial on multiple behaviour changes as sequential or concurrent tasks

Background: This paper explores smoking cessation participants’ perceptions of attempting weight management alongside smoking cessation within the context of a health improvement intervention implemented in Glasgow, Scotland. <p/>Methods: One hundred and thirty-eight participants were recruited from smoking cessation classes in areas of multiple deprivation in Glasgow and randomised to intervention, receiving dietary advice, or to control groups. The primary outcome of the study was to determine the % change in body weight. Semi-structured interviews were conducted with a purposive sample of 15 intervention and 15 control participants at weeks 6 (during the intervention) and 24 (at the end of the intervention). The current paper, though predominantly qualitative, links perceptions of behaviour modification to % weight change and cessation rates at week 24 thereby enabling a better understanding of the mediators influencing multiple behaviour change. <p/>Results: Our findings suggest that participants who perceive separate behaviour changes as part of a broader approach to a healthier lifestyle, and hence attempt behaviour changes concurrently, may be at comparative advantage in positively achieving dual outcomes. <p/>Conclusions: These findings highlight the need to assess participants’ preference for attempting multiple behaviour changes sequentially or simultaneously in addition to assessing their readiness to change. Further testing of this hypothesis is warranted

A late, infrared flash from the afterglow of GRB 050319

We report the detection of a bright, near-infrared flash from the afterglow of GRB 050319, 6.15 hours after the burst. The IR flash faded rapidly from J=13.12 mag. to J > 15.5 mag. in about 4 minutes. There are no reported simultaneous observations at other wavelengths making it an unique event. We study the implications of its late timing in the context of current theoretical models for GRB afterglows.Comment: Accepted in ApJ (Letters

Effect of waste plastics addition on the reduction of iron oxide by metallurgical coke

This work investigates the effect of waste plastics (high density polyethylene (HDPE)) addition on the production of premium grade iron nuggets from iron oxide using metallurgical coke as reducing agent. Composite pellets were formed from mixtures of iron oxide and carbonaceous materials consisting of coke, HDPE and three blends of coke-HDPE. The iron oxidecarbonaceous material composites were heated very rapidly in a laboratory scale horizontal tube furnace at 1500°C in a continuous stream of argon and the off gas was analysed continuously using an online infrared gas analyser and a gas chromatographic analyser. Elemental analyses of samples of the reduced metal were performed chemically for its carbon content and the extent of reduction was calculated based on a mass balance for removable oxygen. The results indicate that blending of coke with HDPE has the beneficial effect of improving the extent of reduction of iron oxide, with the time for complete reduction improving significantly from 600s (Coke) to 330s for Blends 1 and 2. Blending of coke with HDPE led to over 20% reduction in direct carbon dioxide emissions.Keywords: HDPE, coke, reduction, carburisation, iron oxid

Nurturing the young shoots of talent: Using action research for exploration and theory building

This is an Author's Accepted Manuscript of an article published in European Early Childhood Education Research Journal, 19(4), 433-450, 2011, copyright Taylor & Francis, available online at: http://www.tandfonline.com/10.1080/1350293X.2011.623515.This paper reports the outcomes of a set of action research projects carried out by teacher researchers in 14 local education authorities in England, working collaboratively with university tutors, over a period of three years. The common aim of all the projects was to explore practical ways of nurturing the gifts and talents of children aged four–seven years. The project was funded by the Department of Education and Skills in England as part of the government's gifted and talented programme. The project teachers felt that their understanding of issues relating to nurturing the gifts and talents of younger children was enhanced through their engagement in the project. It was possible to map the findings of the projects to the English government's National Quality Standards for gifted and talented education which include: (1) identification; (2) effective provision in the classroom; (3) enabling curriculum entitlement and choice; (4) assessment for learning; (5) engaging with community, families and beyond. The findings are also analysed within the framework of good practice in educating children in the first years of schooling. Participating practitioners felt that action research offered them a suitable methodology to explore the complexity of the topic of giftedness through cycles of planning, action and reflection and personal theory building

Mathematically gifted and talented learners: Theory and practice

This is an Author's Accepted Manuscript of an article published in International Journal of Mathematical Education in Science and Technology, 40(2), 213-228, 2009, copyright Taylor & Francis, available online at: http://www.tandfonline.com/10.1080/00207390802566907.There is growing recognition of the special needs of mathematically gifted learners. This article reviews policy developments and current research and theory on giftedness in mathematics. It includes a discussion of the nature of mathematical ability as well as the factors that make up giftedness in mathematics. The article is set in the context of current developments in Mathematics Education and Gifted Education in the UK and their implications for Science and Technology. It argues that early identification and appropriate provision for younger mathematically promising pupils capitalizes on an intellectual resource which could provide future mathematicans as well as specialists in Science or Technology. Drawing on a Vygotskian framework, it is suggested that the mathematically gifted require appropriate cognitive challenges as well as attitudinally and motivationally enhancing experiences. In the second half of this article we report on an initiative in which we worked with teachers to identify mathematically gifted pupils and to provide effective enrichment support for them, in a number of London Local Authorities. A number of significant issues are raised relating to the identification of mathematical talent, enrichment provision for students and teachers’ professional development

Mitral valve replacement for rheumatic heart disease in Southern Africa

Background: Threshold countries like South Africa provide cardiac surgery to a largely indigent population with rheumatic heart disease. Although repairs are a preferred treatment modality many rheumatic mitral valves can only be replaced. In view of significantly improved primary health care and broad access of the indigent population to communication technology we revisited the efficacy of mitral valve replacement (MVR) at the interface of the developing and developed world. Methods: A cohort of 280 patients (mean age 40.7±13.7y/range 12-80y/median 41y; 76.4% female) with rheumatic heart disease (21% MR; 11% MS; 68% mixed) undergoing mitral valve replacement (MVR) (88.2% mechanical versus 11.8% tissue valves) was analyzed

Decentralization in Bitcoin and Ethereum Networks

Blockchain-based cryptocurrencies have demonstrated how to securely implement traditionally centralized systems, such as currencies, in a decentralized fashion. However, there have been few measurement studies on the level of decentralization they achieve in practice. We present a measurement study on various decentralization metrics of two of the leading cryptocurrencies with the largest market capitalization and user base, Bitcoin and Ethereum. We investigate the extent of decentralization by measuring the network resources of nodes and the interconnection among them, the protocol requirements affecting the operation of nodes, and the robustness of the two systems against attacks. In particular, we adapted existing internet measurement techniques and used the Falcon Relay Network as a novel measurement tool to obtain our data. We discovered that neither Bitcoin nor Ethereum has strictly better properties than the other. We also provide concrete suggestions for improving both systems.Comment: Financial Cryptography and Data Security 201
