A two phases queueing system with Bernoulli vacation schedule under multiple vacation policy

This paper deals with a single server Poisson arrival queue with two phases of heterogeneous service along with a Bernoulli schedule vacation model, where after two successive phases service the server either goes for a vacation with probability p (0≤p≤1) or may continue to serve the next unit, if any, with probability q(=1−p). Further the concept of multiple vacation policy is also introduced here. We obtained the queue size distributions at a departure epoch and at a random epoch, Laplace Stieltjes Transform of the waiting time distribution and busy period distribution along with some mean performance measures. Finally we discuss some statistical inference related issues.     

Transformational Leadership, Organizational Culture, Organizational Effectiveness, and Programme Outcomes in Non-Governmental Organizations

This study examines whether transformational leadership influences organizational culture that furthers NGOs?? effectiveness. It also examines whether transformational leadership at the top directly influences NGOs?? effectiveness. Further, it tests whether NGO effectiveness improves the programme outcomes in terms of health, income, education, and happiness of villagers. Data were collected from 312 NGOs in Jharkhand state (India). Transformational leadership, organizational culture, and NGO effectiveness were assessed from NGO personnel using standard instruments, and programme outcomes on health, income, education, and happiness were evaluated from villagers using wooden cubes. Findings reveal that transformational leadership builds organizational culture that furthers NGO effectiveness. Transformational leadership does not influence directly NGO effectiveness but it enhances NGO effectiveness promoting organizational culture. Furthermore, NGO effectiveness improves the outcomes of programmes undertaken by NGOs in terms of better health, income, education, and happiness of beneficiaries.     

The Colour of Poverty: A Study of the Poverty of Ethnic and Immigrant Groups in Canada

This article uses a case-study approach in relation to the migration of Indian doctors to the UK in order to illustrate the complexity and multi-levelled nature of explanations for international migration.
It argues that whereas, at the level of discursive consciousness, the movement of Indian doctors to the UK appears an economically driven and shapedphenomenon akin to other examples of highly skilled international migration, when the practical consciousness of participants is investigated through qualitative methods, the migration can also be seen as a cultural and social phenomenon.
Although migrants move to "better themselves", they also make choices based on factors such as the kind of novels they read as children or "taken for granted" familial obligations rooted in the everyday life of their culture.     

Double Advantage? Violence Against Canadian Migrant Women from “Developed” Nations

Using a theoretical synthesis based in the Nested Ecological framework, the study examines an anomaly from our previous investigation (Brownridge and Halli, 2002) in which we were surprised to find that immigrant women from "developed" nations have a lower prevalence of violence than Canadian-born women. Based on a representative sample of 6,581 women, the results of the present study show that the key variables that account for this anomalous finding are at the microsystem level. More specifically, a tendency for partners of immigrant women from "developed" nations to be highly educated, and for immigrant women from "developed" nations to have longer-term relationships and be less likely to have young children in the home, appear to account for their lower likelihood of violence. These results are placed in the context of the unique situation of immigrants from "developed" nations and a selection hypothesis is articulated as underpinning the results.     

A note on the queue with a random set-up time under a restricted admissibility policy with a Bernoulli vacation schedule

This paper deals with the queue size distribution of an M^x/G/1 queue with a random set-up time and with a Bernoulli vacation schedule under a restricted admissibility policy. This generalizes the model studied by Madan and Choudhury [Sankhyá 66 (2004) 175–193].     

Face Preferences for Infant‐ and Adult‐Directed Speakers in Infants of Depressed and Nondepressed Mothers: Association with Infant Cognitive Development

Face preferences for speakers of infant‐directed and adult‐directed speech (IDS and ADS) were investigated in 4‐ to 13.5‐month‐old infants of depressed and nondepressed mothers. Following 1 min of exposure to an ID or AD speaker (order counterbalanced), infants had an immediate paired‐comparison test with a still, silent image of the familiarized versus a novel face. In the test phase, ID face preference ratios were significantly lower in infants of depressed than nondepressed mothers. Infants' ID face preference ratios, but not AD face preference ratios, correlated with their percentile scores on the cognitive (Cog) scale of the Bayley Scales of Infant & Toddler Development (3rd Edition; BSID‐III), assessed concurrently. Regression analyses revealed that infant ID face preferences significantly predicted infant Cog percentiles even after demographic risk factors and maternal depression had been controlled. Infants may use IDS to select social partners who are likely to support and facilitate cognitive development.     

农村基本公共品的社区供给:山东省30个村庄的调查

一、概念界定与研究方法 1、概念界定 "农村基本公共品"作为本文的主要概念对象,其内涵限定于国际通行的发展中国家"基本社会服务"范畴,即指基础公共生活设施(生活用水、供电、村庄道路)、初级教育、初级医疗、养老服务和社会救助等最基本的生活资源."所有这些服务对于保证基本的生活质量、维持人们的劳动力和健康都是最必需的"①;联合国发展组织通常也根据类似的定义界定基本社会服务或产品的内涵②.这些基本的生活性公共品或服务以社区居民为直接受益者、在某种程度具有萨缪尔森(Samuelson)所定义的消费的非竞争性、受益的非排他性③以及效用的不可分性特征.由此,本文所研究的基本公共品属于基础性社会服务和生活资料,与那些生产性公共品和其他社会性公共品(如治安、精神文明教育等)有所区别.     

Double jeopardy?: Violence against immigrant women in Canada

Using a theoretical synthesis based in Nested Ecological Theory, the study fills a gap in the extant literature through an investigation of the prevalence and causes of violence against immigrant women in Canada. Based on a representative sample of 7,115 women, the results show that immigrant women from developing countries have the highest prevalence of violence. The analyses demonstrate that several variables operate differently in the production of violence against immigrant women from developed and developing nations. However, the key difference in explaining the higher prevalence of violence among those from developing countries is the sexually proprietary behavior exhibited by their partners. The results further show that sexual jealousy interacts with high female education and low male education levels in the prediction of violence among immigrant women from developing countries. Implications for future research are identified.     

Health Care and Female Survivors of Childhood Sexual Abuse: Health Professionals' Perspectives

The present study explored health professionals' experiences with adult survivors of child sexual abuse in New Zealand. Face-to-face, semistructured interviews of up to an hour took place with 13 health professionals. The participants were asked about training, screening practices, their response to disclosures, and advice to other health professionals. A model—transition to ethical practice—emerged from the data, where delivering more sensitive health care to child sexual abuse survivors sits on a continuum from lack of awareness of child sexual abuse to delivery of care where all patients are comfortable. We recommend making sensitive care for all as the standard care of practice and providing training for health professionals on how to deal with disclosures.
