Search for lepton flavor violating decays of a heavy neutral particle in p-pbar collisions at root(s)=1.8 TeV
We report on a search for a high mass, narrow width particle that decays
directly to e+mu, e+tau, or mu+tau. We use approximately 110 pb^-1 of data
collected with the Collider Detector at Fermilab from 1992 to 1995. No evidence
of lepton flavor violating decays is found. Limits are set on the production
and decay of sneutrinos with R-parity violating interactions.Comment: Figure 2 fixed. Reference 4 fixed. Minor changes to tex
Usefulness of hospital emergency department records to explore access to injury care in Nepal
© 2016, Bhatta et al. Background: Injuries are a major public health problem worldwide. Despite increasing morbidity and mortality from injuries in Nepal, it is not recognised in the government’s policy and programmes and few population-based studies have been published. This study describes the usefulness of hospital emergency department records to explore access to injury care in Nepal. Methods: A retrospective ED-based study was conducted at a governmental hospital in Nepal to review the routinely collected data for 1year (1 January 2010 to 31 December 2010). The study was designed to provide cross-sectional data to describe the distribution of injuries by age, gender, ethnic group and injury mechanism. Results: Results showed that twice as many males as females attended the emergency department (14.6 vs. 7.0 per 1000), attendance varied by age with most (39.8%) attendances in young adults of working age and over half of attendances were from just two ethnic groups (Brahmin (26%) and Tamang (25.5%). Road traffic injuries were the most common cause of injury (37.6%). Conclusions: This study therefore showed the feasibility of using routinely collected hospital emergency department data to monitor injury inequalities in Nepal
Academic self-concept, gender and single-sex schooling
This paper assesses gender differences in academic self-concept for a cohort of children born in 1958 (the National Child Development Study). We address the question of whether attending single-sex or co-educational schools affected students’ perceptions of their own academic abilities (academic self-concept). Academic selfconcept was found to be highly gendered, even controlling for prior test scores. Boys had higher self-concepts in maths and science, and girls in English. Single-sex schooling reduced the gender gap in self-concept, while selective schooling was linked to lower academic self-concept overall
The Political Economy of Domestic Tax Reform in Bangladesh: Political Settlements, Informal Institutions and the Negotiation of Reform
This paper explains the persistence of a tax system characterised by low revenue collection and extensive informality in Bangladesh. It combines analysis of long-term formal and informal institutions and of micro-level incentives shaping negotiation of short-term reform. The system is unusually informal, discretionary, and corrupt, but remains resistant to change because it delivers low and predictable tax rates to business, extensive opportunities for corruption to the tax administration, and an important vehicle for fundraising by political leaders and rent distribution to their elite supporters. We then explore the dynamics of micro-level reform and external pressure within the constraints of this overarching political bargain
Choice in the context of informal care-giving
Extending choice and control for social care service users is a central feature of current English policies. However, these have comparatively little to say about choice in relation to the informal carers of relatives, friends or older people who are disabled or sick. To explore the realities of choice as experienced by carers, the present paper reviews research published in English since 1985 about three situations in which carers are likely to face choices: receiving social services; the entry of an older person to long-term care; and combining paid work and care. Thirteen electronic databases were searched, covering both the health and social care fields. Databases included: ASSIA; IBSS; Social Care Online; ISI Web of Knowledge; Medline; HMIC Sociological Abstracts; INGENTA; ZETOC; and the National Research Register. The search strategy combined terms that: (1) identified individuals with care-giving responsibilities; (2) identified people receiving help and support; and (3) described the process of interest (e.g. choice, decision-making and self-determination). The search identified comparatively few relevant studies, and so was supplemented by the findings from another recent review of empirical research on carers' choices about combining work and care. The research evidence suggests that carers' choices are shaped by two sets of factors: one relates to the nature of the care-giving relationship; and the second consists of wider organisational factors. A number of reasons may explain the invisibility of choice for carers in current policy proposals for increasing choice. In particular, it is suggested that underpinning conceptual models of the relationship between carers and formal service providers shape the extent to which carers can be offered choice and control on similar terms to service users. In particular, the exercise of choice by carers is likely to be highly problematic if it involves relinquishing some unpaid care-giving activities
VL Mandua 382: The first early maturing, white seeded finger millet cultivar suitable for rainfed organic agro-ecology of the Himalayan region
White seeded finger millet is known to have higher acceptability in the baking and food industry compared to the brown seeded finger millet genotypes. The available white seeded finger millet genotypes are late maturing and blast susceptible thereby reducing their farmer’s acceptability in the north western Himalayan region particularly in Uttarakhand. Keeping this in view, the development of early maturing, blast resistance white seeded finger millet breeding programme was initiated at ICAR –VPKAS, Almora in 2003-04, which resulted in the release of VL Mandua 382in the year 2021, the first early maturing white seeded finger millet cultivar of finger millet suitable for rainfed and organic agro-ecology of the Himalayan region. It was derived from the cross between late maturing, white finger millet genotype WR 2 (obtained from UAS Bangalore) and early maturing and locally adapted blast tolerant brown seeded genotype VL 201. It recorded an average grain yield of 1,198 kg/ha, which was at par with the brown seeded check VL Mandua 324 (1,197 kg/ha) and out yielded the brown seeded check PRM-1 (1,163 kg/ha) by 3.0 per cent in State Varietal Trials (SVT) conducted under organic conditions of the Himalayan region. The grains contain higher calcium (340 mg/100g) and protein (8.8%) in comparison to the brown seeded check variety VL Mandua 324 (294 mg/100gand 6.6%, respectively). It exhibited moderate resistance to leaf, finger and neck blast in the multilocation trials conducted over 9 locations. Considering the speciality trait (white grains), excellent grain quality, matching yield potential with brown seeded check varieties and blast tolerance, the variety was released for cultivation in rainfed organic agro-ecology of Uttarakhand hills
Suffering in silence: consequences of sexual violence within marriage among young women in Nepal
<p>Abstract</p> <p>Background</p> <p>Despite the grave consequences of sexual violence, and it's persistence both within and outside marriages, this subject has received relatively little attention from researchers, policy makers, and programme managers in Nepal. This paper explores the definition of sexual violence and its various forms and consequences as reported by young married women in Nepal. In addition, it describes the coping mechanisms used by young married women to avoid sexual violence perpetrated against them by their husbands.</p> <p>Methods</p> <p>This paper analyzes data collected during the qualitative study on "Sexual violence among young couples in Nepal", conducted amongst two major ethnic groups - Brahmin/Chhetri and Tharu - between 2006 and 2007. The data is comprised of 39 free-lists and 15 in-depth case histories with married women aged 15-24 years. The average rank and Smith's Salience were calculated from the free-listing data. The thematic analysis approach was used for the analysis of information from the case histories.</p> <p>Results</p> <p>Approximately three-quarters (74%) of the young women mentioned 'sex against one's wishes' as sexual violence within marriage (SVWM). Sixty-two percent of respondents described 'forced sex during illness' and 'forced sex after consumption of alcohol' as SVWM. About half of young women (48.7%) who participated in the free-listing exercise reported having experienced SVWM. The types of SVWM ranged from unwanted sexual touch to forced sex. Backache, headache, lower abdominal pain, vaginal bleeding and thoughts of suicide were the most commonly reported negative physical and psychological health consequences of SVWM. Women reported various coping strategies including 'trying to convince husbands', 'sleeping in a separate room', 'visiting maternal home', 'waking up the children', and 'using pretexts such as being ill or menstruating', to avoid SVWM. However, in most cases, women reported that these coping strategies were unsuccessful. Almost all women experiencing SVWM were socially isolated and did not turn to institutions, relatives or friends for advice and support.</p> <p>Conclusions</p> <p>Sexual violence within marriage is common in Nepal. Findings provide circumstantial evidence of links between sexual violence and negative general and reproductive health outcomes for women. Various actions are required to prevent SVWM and provide immediate support to the victims.</p
"Well, it's nobody's responsibility but my own." A qualitative study to explore views about the determinants of health and prevention of knee pain in older adults
Dahlgren and Whitehead's 'rainbow' outlines key determinants of health and has been widely adopted within public health policy and research. Public understanding regarding the determinants of health is, however, relatively unknown, particularly in relation to common chronic joint problems like knee pain. We aimed to explore individual attitudes to the prevention of knee pain, and assess how people make sense of their lives by using the rainbow model to explore social determinants of health
Quality of Water the Slum Dwellers Use: The Case of a Kenyan Slum
As a result of rapid urbanization in a context of economic constraints, the majority of urban residents in sub-Saharan Africa live in slums often characterized by a lack of basic services such as water and sewerage. Consequently, the urban poor often use inexpensive pit latrines and at the same time may draw domestic water from nearby wells. Overcrowding in slums limits the adequate distance between wells and pit latrines so that micro-organisms migrate from latrines to water sources. Sanitary practices in these overcrowded slums are also poor, leading to contamination of these wells. This study sought to assess sanitary practices of residents of a Kenyan urban slum and fecal contamination of their domestic water sources. This cross-sectional study involved 192 respondents from Langas slum, Kenya. Forty water samples were collected from the water sources used by the respondents for laboratory analysis of coliforms. Of these 40 samples, 31 were from shallow wells, four from deep wells, and five from taps. Multiple-tube fermentation technique was used to enumerate coliform bacteria in water. The study found that most people (91%) in the Langas slum used wells as the main source of domestic water, whereas the rest used tap water. Whereas most people used pit latrines for excreta disposal, a substantial percentage (30%) of children excreted in the open field. The estimated distance between the pit latrines and the wells was generally short with about 40% of the pit latrines being less than 15 m from the wells. The main domestic water sources were found to be highly contaminated with fecal matter. Total coliforms were found in 100% of water samples from shallow wells, while 97% of these samples from shallow wells were positive for thermotolerant coliforms. Three out of the four samples from deep wells were positive for total coliforms, while two of the four samples were positive for thermotolerant coliforms. None of the samples from taps were positive for either total or thermotolerant coliforms. Because the presence of thermotolerant coliforms in water indicates fecal contamination, facilitated by the proximity between the wells and pit latrines, the study suggests that the pit latrines were a major source of contamination of the wells with fecal matter. However, contamination through surface runoff during rains is also plausible as indiscriminate excreta disposal particularly by children was also common. Owing to the fecal contamination, there is a high possibility of the presence of disease pathogens in the water; thus, the water from the wells in Langas may not be suitable for human consumption. To address this problem, treatment of the water at community or household level and intensive behavioral change in sanitary practices are recommended. Efforts should be made to provide regulated tap water to this community and to other slums in sub-Saharan Africa where tap water is not accessible. However, more sampling of different water sources is recommended
Measurements of fiducial and differential cross sections for Higgs boson production in the diphoton decay channel at s√=8 TeV with ATLAS
Measurements of fiducial and differential cross sections are presented for Higgs boson production in proton-proton collisions at a centre-of-mass energy of s√=8 TeV. The analysis is performed in the H → γγ decay channel using 20.3 fb−1 of data recorded by the ATLAS experiment at the CERN Large Hadron Collider. The signal is extracted using a fit to the diphoton invariant mass spectrum assuming that the width of the resonance is much smaller than the experimental resolution. The signal yields are corrected for the effects of detector inefficiency and resolution. The pp → H → γγ fiducial cross section is measured to be 43.2 ±9.4(stat.) − 2.9 + 3.2 (syst.) ±1.2(lumi)fb for a Higgs boson of mass 125.4GeV decaying to two isolated photons that have transverse momentum greater than 35% and 25% of the diphoton invariant mass and each with absolute pseudorapidity less than 2.37. Four additional fiducial cross sections and two cross-section limits are presented in phase space regions that test the theoretical modelling of different Higgs boson production mechanisms, or are sensitive to physics beyond the Standard Model. Differential cross sections are also presented, as a function of variables related to the diphoton kinematics and the jet activity produced in the Higgs boson events. The observed spectra are statistically limited but broadly in line with the theoretical expectations
