Long Run Health Impacts of Income Shocks: Wine and Phylloxera in 19th Century France

This paper provides estimates of the long-term effects on height and health of a large income shock experienced in early childhood. Phylloxera, an insect that attacks the roots of grape vines, destroyed 40% of French vineyards between 1863 and 1890, causing major income losses among wine growing families. Because the insects spread slowly from the southern coast of France to the rest of the country, Phylloxera affected different regions in different years. We exploit the regional variation in the timing of this shock to identify its effects. We examine the effects on the adult height, health, and life expectancy of children born in the years and regions affected by the Phylloxera. The shock decreased long run height, but it did not affect other dimensions of health, including life expectancy. We find that, at age 20, those born in affected regions were about 1.8 millimeters shorter than others. This estimate implies that children of wine-growing families born when the vines were affected in their regions were 0.6 to 0.9 centimeters shorter than others by age 20. This is a significant effect since average heights grew by only 2 centimeters in the entire 19th century. However, we find no other effect on health, including infant mortality, life expectancy, and morbidity by age 20.

Temporary Work Visas as US-Haiti Development Cooperation: A Preliminary Impact Evaluation

We report a small-sample, preliminary evaluation of the economic impact of temporary overseas work by Haitian agricultural workers. This work occurs in the United States in the context of a pilot program designed as a form of post-disaster development assistance to Haiti. We find that the effects of matching new seasonal agricultural jobs in the US with Haitian workers differs markedly from the effects of more traditional forms of assistance to Haiti, in three ways: The economic benefits are shared roughly equally between Haiti and the United States; these benefits are very large, including raising the value of Haitian workers' labor by a multiple of fifteen; and the portion of the benefits accruing to Haiti is uncommonly well targeted for the direct benefit of poor Haitian households. We discuss implementation challenges faced by the program and the potential for policies of this kind to complement more traditional forms of development and humanitarian assistance

Science with an ngVLA: Resolving the Radio Complexity of EXor and FUor-type Systems with the ngVLA

Episodic accretion may be a common occurrence in the evolution of young pre-main sequence stars and has important implications for our understanding of star and planet formation. Many fundamental aspects of what drives the accretion physics, however, are still unknown. The ngVLA will be a key tool in understanding the nature of these events. The high spatial resolution, broad spectral coverage, and unprecedented sensitivity will allow for the detailed analysis of outburst systems. The proposed frequency range of the ngVLA allows for observations of the gas, dust, and non-thermal emission from the star and disk.Comment: 8 pages, 1 figure, To be published in the ASP Monograph Series, "Science with a Next-Generation VLA", ed.

Web-based intensive therapeutic contact for eating disorders

Contains fulltext : 121984.pdf (publisher's version ) (Open Access)Although many people suffer from eating disorders, which have high mortality and severe morbidity, only a small number of affected people in the Netherlands are treated by mental health professionals. Eating disorders are often not recognized. Many patients do not ask for help because of shame, a lack of awareness, or denial of the disorder. Even when the disorder is recognized, it is difficult to motivate patients to seek help. As a result, many patients are in urgent need of help.1 p

EXPERIENCES OF DRUG USERS IN IIA CLASS JAIL YOGYAKARTA

United Nations Office on Drugs and Crime (UNODC) estimated that about 149-272 million people or 3.3 % - 6.1 % of world population aged 15-64 years used drugs (even once) during their life time. This estimation will increase with time (BNN, 2011). The number of prisoners suffering HIV/AIDS in recent years were increasing as well if compared to its numbers in the year 2011 from 787 people to 1042 people. It was estimated that in the year 2015, the number of drug users in Indonesia would increase to 5.8 million people, since the number of drug users at the present time were reached 4 million people. For the time being, in Yogyakarta second A class drug jail , the number of drug users were 256 people; this number were constant; its mean that if there was prisoner got his / her freedom, another prisoner was incoming. Data from BNN in August 2013 years, 70% of 4 million drug users in Indonesia were workers (productive aged). Aim; To discovered population research experiences that cause them used drugs and depend on its. Research method: This was qualitative research with phenomenological approach. Data gathering technique were deep interview and FGD toward 30 respondents. Data were analyzed using reduction, data display, and conclusion drawing/verification. The majority of respondents mentioned that they used drugs because of they wanted to know and the influence of friends. Drugs, kinds of sabu, used to increase energy and ganja were used to obtain peacefulness. Drugs users wanted to use its forever; therefore, they wanted to stop because of punishment to be in jail not because of the drugs had negative effects to the body. The majority of respondents mentioned that to stop using drugs must be self motivated; on the contrary, the obstacle to stop using drugs because of missing sensation to use it. They named it suggest. Using drugs were conducted by research population because of environmental influence, to increase energy and to obtain peacefulness. Keywords : The experiences of drug use

Effectiveness of a web-based treatment program using intensive therapeutic support for female patients with bulimia nervosa, binge eating disorder and eating disorders not otherwise specified: study protocol of a randomized controlled trial

Background: Disordered eating behavior and body dissatisfaction affect a large proportion of the Dutch population and account for severe psychological, physical and social morbidity. Yet, the threshold for seeking professional care is still high. In the Netherlands, only 7.5% of patients with bulimia nervosa and 33% of patients with anorexia nervosa are treated within the mental health care system. Easily accessible and low-threshold interventions, therefore, are needed urgently. The internet has great potential to offer such interventions. The aim of this study is to determine whether a web-based treatment program for patients with eating disorders can improve eating disorder psychopathology among female patients with bulimia nervosa, binge eating disorder and eating disorders not otherwise specified. Methods/design: This randomized controlled trial will compare the outcomes of an experimental treatment group to a waiting list control group. In the web-based treatment program, participants will communicate personally and asynchronously with their therapists exclusively via the internet. The first part of the program will focus on analyzing eating attitudes and behaviors. In the second part of the program participants will learn how to change their attitudes and behaviors. Participants assigned to the waiting list control group will receive no-reply email messages once every two weeks during the waiting period of 15 weeks, after which they can start the program. The primary outcome measure is an improvement in eating disorder psychopathology as determined by the Eating Disorder Examination Questionnaire. Secondary outcomes include improvements in body image, physical and mental health, body weight, self-esteem, quality of life, and social contacts. In addition, the participants’ motivation for treatment and their acceptability of the program and the therapeutic alliance will be measured. The study will follow the recommendations in the CONSORT statement relating to designing and reporting on RCTs. Discussion: This study protocol presents the design of a RCT for evaluating the effectiveness of a web-based treatment program using intensive therapeutic support for female patients with bulimia nervosa, binge eating disorder and eating disorders not otherwise specified

A survey of performance enhancement of transmission control protocol (TCP) in wireless ad hoc networks

This Article is provided by the Brunel Open Access Publishing Fund - Copyright @ 2011 Springer OpenTransmission control protocol (TCP), which provides reliable end-to-end data delivery, performs well in traditional wired network environments, while in wireless ad hoc networks, it does not perform well. Compared to wired networks, wireless ad hoc networks have some specific characteristics such as node mobility and a shared medium. Owing to these specific characteristics of wireless ad hoc networks, TCP faces particular problems with, for example, route failure, channel contention and high bit error rates. These factors are responsible for the performance degradation of TCP in wireless ad hoc networks. The research community has produced a wide range of proposals to improve the performance of TCP in wireless ad hoc networks. This article presents a survey of these proposals (approaches). A classification of TCP improvement proposals for wireless ad hoc networks is presented, which makes it easy to compare the proposals falling under the same category. Tables which summarize the approaches for quick overview are provided. Possible directions for further improvements in this area are suggested in the conclusions. The aim of the article is to enable the reader to quickly acquire an overview of the state of TCP in wireless ad hoc networks.This study is partly funded by Kohat University of Science & Technology (KUST), Pakistan, and the Higher Education Commission, Pakistan

Comparison of different in situ hybridization techniques for the detection of various RNA and DNA viruses

In situ hybridization (ISH) is a technique to determine potential correlations between viruses and lesions. The aim of the study was to compare ISH techniques for the detection of various viruses in different tissues. Tested RNA viruses include atypical porcine pestivirus (APPV) in the cerebellum of pigs, equine and bovine hepacivirus (EqHV, BovHepV) in the liver of horses and cattle, respectively, and Schmallenberg virus (SBV) in the cerebrum of goats. Examined DNA viruses comprise canine bocavirus 2 (CBoV-2) in the intestine of dogs, porcine bocavirus (PBoV) in the spinal cord of pigs and porcine circovirus 2 (PCV-2) in cerebrum, lymph node, and lung of pigs.

Role of Interaction and Nucleoside Diphosphate Kinase B in Regulation of the Cystic Fibrosis Transmembrane Conductance Regulator Function by cAMP-Dependent Protein Kinase A

Cystic fibrosis results from mutations in the cystic fibrosis transmembrane conductance regulator (CFTR), a cAMP-dependent protein kinase A (PKA) and ATP-regulated chloride channel. Here, we demonstrate that nucleoside diphosphate kinase B (NDPK-B, NM23-H2) forms a functional complex with CFTR. In airway epithelia forskolin/IBMX significantly increases NDPK-B co-localisation with CFTR whereas PKA inhibitors attenuate complex formation. Furthermore, an NDPK-B derived peptide (but not its NDPK-A equivalent) disrupts the NDPK-B/CFTR complex in vitro (19-mers comprising amino acids 36-54 from NDPK-B or NDPK-A). Overlay (Far-Western) and Surface Plasmon Resonance (SPR) analysis both demonstrate that NDPK-B binds CFTR within its first nucleotide binding domain (NBD1, CFTR amino acids 351-727). Analysis of chloride currents reflective of CFTR or outwardly rectifying chloride channels (ORCC, DIDS-sensitive) showed that the 19-mer NDPK-B peptide (but not its NDPK-A equivalent) reduced both chloride conductances. Additionally, the NDPK-B (but not NDPK-A) peptide also attenuated acetylcholine-induced intestinal short circuit currents. In silico analysis of the NBD1/NDPK-B complex reveals an extended interaction surface between the two proteins. This binding zone is also target of the 19-mer NDPK-B peptide, thus confirming its capability to disrupt NDPK-B/CFTR complex. We propose that NDPK-B forms part of the complex that controls chloride currents in epithelia
