Does the village fund matter in Thailand ?

This paper evaluates the impact of the Thailand Village and Urban Revolving Fund on household expenditure, income, and assets. The revolving fund was launched in 2001 when the Government of Thailand promised to provide a million baht (about $22,500) to every village and urban community in Thailand as working capital for locally-run rotating credit associations. The money – about$2 billion in total – was quickly disbursed to locally-run committees in almost all of Thailand’s 74,000 villages and more than 4,500 urban (including military) communities. By May 2005, the committees had lent a total of about $8 billion, with an average loan of$466. Using data from the Thailand Socioeconomic Surveys of 2002 and 2004, each of which surveys almost 35,000 households, the authors find that the borrowers were disproportionately poor and agricultural. A propensity score matching model finds that Fund borrowing in 2004 was associated with, on average, 1.9 percent more income, 3.3 percent more expenditure, and about 5 percent more ownership of durable goods. These results are broadly consistent with the results from instrumental variables models (where the identifying instrument was the inverse of village size), which however show a smaller (marginal) effect. Households that borrowed both from the revolving fund and from the Bank of Agriculture and Agricultural Cooperatives gained substantially more in terms of higher income than those who borrowed from either one or the other or from neither.Access to Finance,,Debt Markets,Economic Theory&Research,Rural Poverty Reduction

Evaluating the impact of Egyptian social fund for development programs

The Egyptian Social Fund for Development was established in 1991 with a mandate to reduce poverty. Since its inception, it has disbursed about $2.5 billion, of which nearly two-fifths was devoted to supporting microcredit and financing community development and infrastructure. This paper investigates the size of the impact of the Fund’s interventions, whether the benefits have been commensurate with the costs, and whether the programs have been targeted successfully to the poor. The core of the impact evaluation applies propensity-score matching to data from the 2004/2005 national Household Income, Expenditure and Consumption Survey. The authors find that Egypt’s Social Fund for Development programs have had clear and measurable effects, in the expected direction, for all of the programs considered: educational interventions have reduced illiteracy, health and potable water programs have lowered household spending on health, sanitation interventions have cut household spending on sanitation and lowered poverty, and road projects have reduced household transportation costs by 20 percent. Microcredit is associated with higher household expenditures in metropolitan areas and urban Upper Egypt, but not elsewhere. The Social Fund for Development’s road projects generate benefits that, by some estimates, exceed the costs, as do health and potable water interventions; this is less evident for interventions in education and sanitation. The Fund argues that its mission is primarily social, and so should not be judged using a cost-benefit analysis. The Fund support for microcredit is strongly pro-poor; the other programs analyzed have a more modest pro-poor orientation.Health Monitoring&Evaluation,,Rural Poverty Reduction,Housing&Human Habitats,Population Policies

Model selection in High-Dimensions: A Quadratic-risk based approach

In this article we propose a general class of risk measures which can be used for data based evaluation of parametric models. The loss function is defined as generalized quadratic distance between the true density and the proposed model. These distances are characterized by a simple quadratic form structure that is adaptable through the choice of a nonnegative definite kernel and a bandwidth parameter. Using asymptotic results for the quadratic distances we build a quick-to-compute approximation for the risk function. Its derivation is analogous to the Akaike Information Criterion (AIC), but unlike AIC, the quadratic risk is a global comparison tool. The method does not require resampling, a great advantage when point estimators are expensive to compute. The method is illustrated using the problem of selecting the number of components in a mixture model, where it is shown that, by using an appropriate kernel, the method is computationally straightforward in arbitrarily high data dimensions. In this same context it is shown that the method has some clear advantages over AIC and BIC.Comment: Updated with reviewer suggestion

Entrances and exits: changing perceptions of primary teaching as a career for men

Original article can be found at: http://www.informaworld.com/smpp/title~content=t713640830~db=all Copyright Informa / Taylor and Francis. DOI: 10.1080/03004430802352087The number of men in teaching has always been small, particularly in early childhood, but those that do come into teaching usually do so for the same reasons as women, namely enjoyment of working with children, of wanting to teach and wanting to make a difference to children's lives. However, in two separate studies, the authors have shown that on beginning teacher training in 1998, and at the point of leaving the profession in 2005, men and women tend to emphasise different concerns. This article will explore those differences and seek possible explanations for how men's views of teaching might be changing over time.Peer reviewe

Two separate functions of class II (Ia) molecules: T-cell stimulation and B-cell excitation.

We have evaluated the role of major histocompatibility complex-encoded class II (Ia) molecules as transmembrane signaling receptors in the T helper cell-dependent activation of B lymphocytes. For these studies, we utilized the murine B-cell lymphoma CH12, which expresses both I-A and I-E class II molecules. In addition, CH12 cells carry IgM of known antigen specificity and require both specific antigen and Ia-restricted T-cell help for the induction of antibody secretion. In this respect, they resemble normal resting B cells. We have studied the ability of antigen-specific or alloreactive T helper cells reactive with either the I-A or the I-E molecules on CH12 to be activated and their ability to stimulate antibody production by CH12. The results show that, although CH12 cells present antigen to T helper cells that interact with either the I-A or the I-E molecules, CH12 cells are stimulated to secrete antibody only by T helper cells reactive with their I-E molecules. Our data demonstrate that class II molecules are transducers of signals for B-cell excitation in addition to serving a restricting function for helper T-cell stimulation. Moreover, the data demonstrate that these two functions, T-cell stimulation and B-cell excitation, are discrete and need not be expressed by the same Ia molecule

Birmingham’s Eastside story: making steps towards sustainability?

Sustainability has come to play a dominant discursive role in the UK planning system, particularly relating to urban regeneration. The purpose of this paper is to evaluate the role that sustainability plays in a major regeneration programme, known as Eastside, currently underway in Birmingham, the UK. That this £6 billion redevelopment is now widely talked about by such key players as Birmingham City Council and the Regional Development Agency, Advantage West Midlands, as having a central sustainability agenda points to the growing importance of the ideal of sustainability in planning and regeneration agendas. In this paper, we investigate in detail how and why sustainability has become part of the planning discourse for Eastside and critically evaluate what impact, if any, this is having on public policy decision-making

Ontogenetic scaling patterns and functional anatomy of the pelvic limb musculature in emus (Dromaius novaehollandiae)

Emus (Dromaius novaehollandiae) are exclusively terrestrial, bipedal and cursorial ratites with some similar biomechanical characteristics to humans. Their growth rates are impressive, as their body mass increases eighty-fold from hatching to adulthood whilst maintaining the same mode of locomotion throughout life. These ontogenetic characteristics stimulate biomechanical questions about the strategies that allow emus to cope with their rapid growth and locomotion, which can be partly addressed via scaling (allometric) analysis of morphology. In this study we have collected pelvic limb anatomical data (muscle architecture, tendon length, tendon mass and bone lengths) and calculated muscle physiological cross sectional area (PCSA) and average tendon cross sectional area from emus across three ontogenetic stages (n = 17, body masses from 3.6 to 42 kg). The data were analysed by reduced major axis regression to determine how these biomechanically relevant aspects of morphology scaled with body mass. Muscle mass and PCSA showed a marked trend towards positive allometry (26 and 27 out of 34 muscles respectively) and fascicle length showed a more mixed scaling pattern. The long tendons of the main digital flexors scaled with positive allometry for all characteristics whilst other tendons demonstrated a less clear scaling pattern. Finally, the two longer bones of the limb (tibiotarsus and tarsometatarsus) also exhibited positive allometry for length, and two others (femur and first phalanx of digit III) had trends towards isometry. These results indicate that emus experience a relative increase in their muscle force-generating capacities, as well as potentially increasing the force-sustaining capacities of their tendons, as they grow. Furthermore, we have clarified anatomical descriptions and provided illustrations of the pelvic limb muscle–tendon units in emus

Public opinion on energy crops in the landscape: considerations for the expansion of renewable energy from biomass

Public attitudes were assessed towards two dedicated biomass crops – Miscanthus and Short Rotation Coppice (SRC), particularly regarding their visual impacts in the landscape. Results are based on responses to photographic and computer-generated images as the crops are still relatively scarce in the landscape. A questionnaire survey indicated little public concern about potential landscape aesthetics but more concern about attendant built infrastructure. Focus group meetings and interviews indicated support for biomass end uses that bring direct benefits to local communities. Questions arise as to how well the imagery used was able to portray the true nature of these tall, dense, perennial plants but based on the responses obtained and given the caveat that there was limited personal experience of the crops, it appears unlikely that wide-scale planting of biomass crops will give rise to substantial public concern in relation to their visual impact in the landscape

Workforce capacity to address obesity: a Western Australian cross-sectional study identifies the gap between health priority and human resources needed

Background: The disease burden due to poor nutrition, physical inactivity and obesity is high and increasing. An adequately sized and skilled workforce is required to respond to this issue. This study describes the public health nutrition and physical activity (NAPA) practice priorities and explores health managers and practitioner’s beliefs regarding workforce capacity to deliver on these priorities. Methods: A workforce audit was conducted including a telephone survey of all managers and a postal survey of practitioners working in the area of NAPA promotion in Western Australia in 2004. Managers gave their perspective on workforce priorities, current competencies and future needs, with a 70 % response rate. Practitioners reported on public health workforce priorities, qualifications and needs, with a 56 % response rate. Results: The top practice priorities for managers were diabetes (35 %), alcohol and other drugs (33 %), and cardiovascular disease (27 %). Obesity (19 %), poor nutrition (15 %) and inadequate physical activity (10 %) were of lower priority. For nutrition, managers identified lack of staff (60.4 %), organisational and management factors (39.5 %) and insufficient financial resources (30.2 %) as the major barriers to adequate service delivery. For physical activity services, insufficient financial resources (41.7 %) and staffing (35.4 %) and a lack of specific physical activity service specifications (25.0 %) were the main barriers. Practitioners identified inadequate staffing as the main barrier to service delivery for nutrition (42.3 %) and physical activity (23.3 %). Ideally, managers said they required 152 % more specialist nutritionists in the workforce and 131 % specialists for physical activity services to meet health outcomes in addition to other generalist staff. Conclusion: Human and financial resources and organisational factors were the main barriers to meeting obesity, and public health nutrition and physical activity outcomes. Services were being delivered by generalists rather than specialists, which may reduce service effectiveness. Although conclusions from this research need to take into account the fact that the audit was conducted in 2004, the findings suggest that there was a need to equip health services with an adequately skilled workforce of sufficient capacity to deliver an effective public health response to the obesity epidemic, particularly addressing poor nutrition and physical inactivity
