A robust QTL mapping procedure

In quantitative trait linkage studies using experimental crosses, the conventional normal location-shift model or other parameterizations may be unnecessarily restrictive. We generalize the mapping problem to a genuine nonparametric setup and provide a robust estimation procedure for the situation where the underlying phenotype distributions are completely unspecified. Classical Wilcoxon–Mann–Whitney statistics are employed for point and interval estimation of QTL positions and effects.     

Analysis of supersaturated designs via the Dantzig selector

A supersaturated design is a design whose run size is not enough for estimating all the main effects. It is commonly used in screening experiments, where the goals are to identify sparse and dominant active factors with low cost. In this paper, we study a variable selection method via the Dantzig selector, proposed by Candes and Tao [2007. The Dantzig selector: statistical estimation when p$p$ is much larger than n$n$. Annals of Statistics 35, 2313–2351], to screen important effects. A graphical procedure and an automated procedure are suggested to accompany with the method. Simulation shows that this method performs well compared to existing methods in the literature and is more efficient at estimating the model size.     

Optimum covariate designs in partially balanced incomplete block (PBIB) design set-ups

The use of covariates in block designs is necessary when the covariates cannot be controlled like the blocking factor in the experiment. In this paper, we consider the situation where there is some flexibility for selection in the values of the covariates. The choice of values of the covariates for a given block design attaining minimum variance for estimation of each of the parameters has attracted attention in recent times. Optimum covariate designs in simple set-ups such as completely randomised design (CRD), randomised block design (RBD) and some series of balanced incomplete block design (BIBD) have already been considered. In this paper, optimum covariate designs have been considered for the more complex set-ups of different partially balanced incomplete block (PBIB) designs, which are popular among practitioners. The optimum covariate designs depend much on the methods of construction of the basic PBIB designs. Different combinatorial arrangements and tools such as orthogonal arrays, Hadamard matrices and different kinds of products of matrices viz. Khatri–Rao product, Kronecker product have been conveniently used to construct optimum covariate designs with as many covariates as possible.     

Islamic Jurisprudence of Minorities (Fiqh al-Aqalliyyat): The Case of the Palestinian Muslim Minority in Israel

This article examines the doctrine of Jurisprudence of Muslim Minorities (Fiqh al-Aqalliyyat) in the context of the Palestinian Muslim community in Israel. The first part discusses the origins and goals of Fiqh al-Aqalliyyat. After outlining the particular historical and political context of the Palestinian minority in Israel, the article focuses on the ethno-religious political mobilization developed by the Muslim community vis-à-vis the state’s strategies of control and domination, and points out the difficulties involved in the application of Fiqh al-Aqalliyyat, as used in “Western” states, for the reality that Muslims face in Israel. The article suggests a vigilant approach toward the Jurisprudence of Minorities, as we argue that, when applying it in this context of the Muslim community in Israel, this doctrine has two substantial limitations. The first is theoretical and it concerns the doctrine’s current incapability to distinguish between different types of minorities, as well as failing to recognize a difference between various political regimes and societal lives that might be inherently less or more accommodating or even hostile to minorities, and Muslim minority communities in particular. The second limitation relates to the political dimension and the lack of consideration for the status of the Palestinian minority as an indigenous and national minority and not an immigrant minority. Their status as national minorities, at times also as indigenous peoples, who are perceived as entitled to group-based “self-government rights”, poses a serious challenge to this doctrine’s scope and viability.     

Women–Family in Quality Perspective

Bringing together women and family in quality perspective bring about interesting discussions in this paper. By integrating previous studies and considering expert opinions, we determinate the variables and dimensions with respect to women’s existence regarding their roles both in the family and at work. Many activities carried out by women represent the consumer aspects of their role. Women undertake these activities to fulfill their needs, which can be classified in the order of preference using Maslow’s Hierarchy of Need. Women success can be measured based on their ability to perform their roles successfully. We identify women’s performance by using quality approach of Personal Quality Maintenance (PQM), which is widely applied in many organizations in order to maintain the service delivery, which meets the customer satisfaction. The effort to enhance women’s satisfaction for their success in playing the multirole in the family and at work is our main consideration. This study may contribute a new point of view regarding for the women’s welfare and existence.     

Perceptions of aging among rural, midwestern senior citizens: signs of women's resiliency

This study utilized both quantitative and qualitative approaches to examine perceptions of aging among rural-dwelling senior citizens (203 women and 112 men), ages 65 and older. Quantitative results revealed that, despite no significant gender differences in the total number of medical conditions reported, women were less likely than men to report that health problems interfered with their daily functioning. Qualitative analyses revealed that women were particularly like to identify relationships, frame of mind, participating in activities, and religion/spirituality as important contributors to successful aging.     

The politics of midwifery education and training in New South Wales during the last decades of the 19th Century

This paper focuses on the introduction and development of midwifery education and training in Sydney during the last decades of the 19th century. The aim of the training, it is argued, was to displace the lay midwives by trained midwifery nurses who would work under medical control. The lay midwives were one of the largest occupational groups among women and two-thirds of births in NSW were being delivered by them in the late 19th century. It was a period of professionalisation of medicine and medical men laid claim to midwifery as a legitimate sphere of their practice and saw it as the gateway for establishing a family practice. The lay midwife stood in the way of their claim. The training programs were established purportedly to control maternal mortality. From the beginning in 1887 medical men were in control of midwifery nurse training. In addition to training at the Benevolent Society Asylum, three more women's hospitals were established in the 1890s in Sydney making it possible to train a stream of midwifery nurses. The midwifery nurses were charged exorbitant fees for their training; the fees contributed substantially towards running the new hospitals that delivered birth services to the poor and destitute women mostly in their homes. The midwifery nurses worked hard in miserable conditions under the guise of clinical experience required for training. When a critical mass of poorly trained midwifery nurses were in the offing, a Bill was introduced into the Parliament in 1895, restricting registration to midwifery nurses and this would have eliminated the lay midwife if passed. It took more than two decades to get a Registration Bill passed in the NSW Parliament.     

HIV testing,perceptions of AIDS risk,and condom use motivation among US women

As STD infections including HIV increase in the United States, it has become increasingly important to policy makers to ascertain the extent to which knowledge and perceptions of AIDS risk affect an individual's probability of altering their sexual or contraceptive behavior to avoid infection. This paper examines the extent to which women's perceptions of their own and their partners' risk of HIV infection affects the probability of using a condom for protection against sexually transmitted diseases. This paper also examines the extent to which HIV testing may affect motivation for condom use. Crosstabulations reveal that prophylactic condom use is more prevalent among women who have been tested for HIV and increase as perceptions of their chance (and their partner's chance) of being positive increases. The multivariate results from this study indicate that having an HIV test significantly predicts the likelihood of using a condom for STD prevention for US women. Furthermore, women who perceive themselves to be at least somewhat likely to be HIV positive have a higher probability of using a condom to prevent sexually transmitted disease, and women who perceive their partners to be HIV positive are twice as likely as other women to use a condom for STD prevention. However, women who consider themselves likely to be HIV positive are no more likely to use a condom than those who consider themselves not at risk.     

A Bayesian Approach for Analyzing Results of Vehicle Collision Tests

Certain motor vehicle safety standards stipulate a collision test speed and a set of performance criteria that vehicles must satisfy during or after the collision test. For example, Federal Motor Vehicle Safety Standard 301 requires a 30 mile per hour (mph) barrier collision and specifies a certain maximum allowable limit on the total spillage of fuel. Vehicle designs are required to meet this standard; however, when collision tests are conducted at speeds higher than the standard, vehicles do not always satisfy the performance criteria. This paper develops a mathematical model for estimating the probability of meeting the standard by using a Bayesian framework to incorporate engineering judgment with collision test results. The model is based on the idea that there are random features to a vehicle's ability to meet performance standards in a collision, especially at such elevated speeds. Example calculations are included to illustrate the estimation of the probability of meeting the standard and to compare it with a maximum likelihood approach.     

An Empirical Examination of Characteristics of Mexican Migrants to Metropolitan and Nonmetropolitan Areas of the United States*

Abstract This research examines differences between those Mexican migrants choosing metropolitan destinations and those choosing destinations outside metropolitan areas of the United States. Using general estimating equations, the study presents data indicating that since the 1960s migrants choosing rural destinations are less fluent in English, slightly older, much less educated, far more likely to be unskilled, more likely to be married, and more likely to be undocumented. The picture is more complex when consideration is restricted to those migrants arriving in rural areas since the passage of the North American Free Trade Agreement. These migrants are far more likely to be single, have more education but have less English fluency, have less work experience, and have less family experience with migration to the United States. They are more likely to come from small towns and rural areas of Mexico.
