This article examines the cultural construction of difference, danger, and disease among the Muslim patrilineal Hadendowa-Beja of eastern Sudan and focuses on the ways in which gendered discourses, together with symbolic and ritualistic practices, diagnose historical relationships of power, powerlessness, and social conflict. In particular, I show how the female body, viewed as a “fertile womb-land,” is the locus of anxieties about foreign dangers and diseases, which are perceived to be threatening to collective identity and well being. By using “foreignness” as a double-edged category linked to both power and danger, I examine how Hadendowa's feminization of social vulnerability draws attention to their own political history of exclusion and displacement.  相似文献

Shewhart, cumulative sum (CUSUM), and exponentially weighted moving average (EWMA) control procedures with variable sampling intervals (VSI) have been investigated in recent years for detecting shifts in the process mean. Such procedures have been shown to be more efficient when compared with the corresponding fixed sampling interval (FSI) charts with respect to the average time to signal (ATS) when the average run length (ARL) values of both types of procedures are held equal. Frequent switching between the different sampling intervals can be a complicating factor in the application of control charts with variable sampling intervals. In this article, we propose using a double exponentially weighted moving average control procedure with variable sampling intervals (VSI-DEWMA) for detecting shifts in the process mean. It is shown that the proposed VSI-DEWMA control procedure is more efficient when compared with the corresponding fixed sampling interval FSI-DEWMA chart with respect to the average time to signal (ATS) when the average run length (ARL) values of both types of procedures are held equal. It is also shown that the VSI-DEWMA procedure reduces the average number of switches between the sampling intervals and has similar ATS properties as compared to the VSI-EMTMA control procedure  相似文献

We estimate sib–sib correlation by maximizing the log-likelihood of a Kotz-type distribution. Using extensive simulations we conclude that estimating sib–sib correlation using the proposed method has many advantages. Results are illustrated on a real life data set due to Galton. Testing of hypothesis about this correlation is also discussed using the three likelihood based tests and a test based on Srivastava's estimator. It is concluded that score test derived using Kotz-type density performs the best.  相似文献

BackgroundWomen's agency, or intentional actions, in combining breastfeeding and employment is significant for health and labour productivity. Previous research in India showed that mothers use various collaborative strategies to ensure a “good enough” combination of breastfeeding and employment. Bandura's theoretical agency constructs previously applied in various realms could facilitate the exploration of agency in an Indian context.AimTo explore manifestations of agency in combining breastfeeding and employment amongst Indian health workers using Bandura's theoretical constructs of agency and women's experiences.MethodsQualitative semi-structured interviews were conducted with ten women employees within the governmental health sector in New Delhi, India. Both deductive and inductive qualitative content analyses were used.FindingsBandura's features and modes of agency revealed that intentionality is underpinned by knowledge, forethought means being prepared, self-reactiveness includes collaboration and that self-reflectiveness gives perspective. Women's interviews revealed four approaches to agency entitled: ‘All within my stride or the knowledgeable navigator’; ‘Much harder than expected, but ok overall’; This is a very lonely job’; and ‘Out of my control’.ConclusionsAgency features and their elements are complex, dynamic and involve family members. Bandura's theoretical agency constructs are partially useful in this context, but additional social practice constructs of family structure and relationship quality are needed for better correspondence with women's experiences of agency. The variation in individual approaches to agency has implications for supportive health and workplace services.  相似文献

Although Muslims in the United States are a growing population, there is limited research on their relational patterns and how they prepare for marriage. We conducted in‐depth interviews with 32 members of the Muslim community in Southeast Michigan including married individuals, divorced individuals, therapists, and imams (Muslim religious leaders) to explore their perceptions and experiences of marriage preparation. Our analysis revealed that marriage preparation varies but is less likely to involve a requirement of premarital counseling, with imams being the primary providers, not therapists. Barriers to participation include stigma, lack of awareness, logistical and financial challenges, and parental influence. Partnerships between imams and therapists, and family and community efforts are necessary to address barriers and increase participation in premarital education programs.  相似文献

Under the hypothesis of white noise, the authors derive the explicit form of the asymptotic representation of linear rank statistics resulting from Hájek's (1968) celebrated projection lemma for linear rank statistics in the so‐called approximate score case. This representation based on Bernstein polynomials is better, in the quadratic mean sense, than the traditional one due to Hájek (1961, 1962). The polynomial representation allows for a new derivation of classical asymptotic results (asymptotic normality, Berry‐Essten bounds). Moreover, a simulation study shows that the quality of the polynomial approximation to the exact finite‐sample distributions of rank statistics is sizeably better than that resulting from the traditional approach.  相似文献

Adopting an intersectional feminist lens, we explore our identities as single and co‐parents thrust into the new reality of the UK COVID‐19 lockdown. As two PhD students, we present shared reflections on our intersectional and divergent experiences of parenting and our attempts to protect our work and families during a pandemic. We reflect on the social constructions of ‘masculinities’ and ‘emphasized femininities’ as complicated influence on our roles as parents. Finally, we highlight the importance of time and self‐care as ways of managing our shared realities during this uncertain period. Through sharing reflections, we became closer friends in mutual appreciation and solidarity as we learned about each other’s struggles and vulnerabilities.  相似文献

A distribution-free runs test for conditional symmetry is proposed. The null distribution of the test statistics is derived. Intensive simulation is conducted to examine the power of the proposed test for different sample sizes and different alternatives. Data on the bilirubin level of babies in neonatal intensive care is used to illustrate the method.  相似文献
