Correlation between pelvic floor strength and physical activity level in healthy men

The male pelvic floor muscles comprise a pair of compound muscle layers referred to as the levator ani. Studies have shown that pelvic floor muscle strength is affected by physical activity. This study aimed to assess male pelvic floor muscle strength through manometry of the external anal sphincter and evaluation of its association with physical activity level, BMI, and rectal pressure in healthy men. To assess physical activity level over the previous week, we used the International Physical Activity Questionnaire 8 (IPAQ). Pelvic floor muscle strength was assessed via anorectal manometry. The results shows a negative correlation between resting pressure and MET, a positive correlation between rectal pressure and resting and maximum pressure. The novel finding of this study is a negative correlation between walking and pelvic floor strength. This study raises new questions about the understanding of the interaction among physical activity, intraabdominal pressure, and pelvic floor strength in the physiology of continence in men.     

The concept of a child within sub‐Saharan African migrant homes: Reconciling culture and child rights

As international migration increases, the Australian socio‐cultural and political context in which sub‐Saharan African migrant families are settling is causing tension between traditional sub‐Saharan African migrant definitions of child and childhood experiences and host nation definitions particularly when compared with the child protection system. This paper seeks to explore and highlight the fundamental values and differences that determine perceptions and treatment of children within traditional sub‐Saharan African communities. Using a qualitative design, this study was influenced by acculturation theory. Four major themes emerged from the analysis: (a) culture and the sub‐Saharan African child, (b) moulding good children, (c) family functioning and relationships, and (d) host context: perceptions of Australian mainstream parenting. The study found that in order to successfully make decisions that are in the best interest of sub‐Saharan African migrant children that come to the attention of the child protection system, discussions about children rights can only yield good outcomes when the child's socio‐cultural environment is considered.     

Gender Identity and Social Services: Barriers to Care

ABSTRACT

Transgender people seek social services for a variety of reasons. This literature review highlights needs assessments and social science research articles (N = 30) from the last 16 years that demonstrate the many ways in which social services are further revictimizing transgender people. Studies indicate that transgender people often encounter ignorance, hostility, and transphobic environments while attempting to access social services, and these environments can dissuade transgender people from gaining needed care. Suggestions are made to address these inequalities and include simple measures that social service agencies can begin with to make their services more transinclusive. Future research should address the bias in social services more directly and also develop a clear plan of action and best practices to help agencies remove discrimination from social service settings.     

Doctoral Study Programs in Social Work at HBCUs: Origin and Program Development

Fisk University began the genesis of HBCU graduate programs in 1880. During the next fifty years, several other HBCUs established graduate programs. That group included Lincoln, Howard, and Morgan State. However, only Lincoln University established a PhD program. The primary goal of this paper is to provide a historical perspective regarding the development of social work doctoral degree programs in the context of HBCU graduate degree program development. Although HBCU social work doctoral programs have only existed since 1978, they are significant and growing academic enterprises which are expanding the pool of doctoral level social work experts and professors of color. Further, these programs should be viewed contextually as producers of scholars on the larger landscape of the academy.

A Fragmented Discourse of Religious Leadership in France: Muslim Youth between Citizenship and Radicalization

Abstract

At a time when public debates about radicalization of Muslim youth in the West are taking center stage and when questions about “home-grown” security threats are increasing in the wake of a number of terrorist attacks in many émigré societies, this article provides fresh empirical insights from the perspective of religious leadership. It outlines a picture of a highly diverse Muslim religious landscape where competing religious discourses are struggling to attract and support Muslim youth facing social dislocation and identity crises within increasingly contested social milieus. The article argues that a typology of religious leadership is clearly emerging where a spectrum of faith-based orientations and religious practice emphasize, to different degrees, notions of attachment to universal ethics and individual agency. The fact that conservative, sometimes radical, interpretations of such contestations represent a minority of voices is heartening even though the actual damage by such minority is often disproportionate to its actual size within the so-called silent majority. The empirical insights provided by the religious leaders interviewed for this study offer hope that the future of Western Muslims is more positive than we are led to think, if the possibility of combining devout faith with local political engagement becomes a real and sustainable conduit towards social inclusion and intercultural understanding and if necessary support and understanding are extended by the host communities.     

Robust designs for first-order multiple design multivariate models

This paper deals with the methodology of obtaining designs that are robust to nonnormality of the error distribution for tests associated with first-order multiple design multivariate linear models.A sequential procedure is given for the generation of the proposed designs.     

The double chain markov model

In the class of discrete time Markovian processes, two models are widely used, the Markov chain and the hidden Markov model. A major difference between these two models lies in the relation between successive outputs of the observed variable. In a visible Markov chain, these are directly correlated while in hidden models they are not. However, in some situations it is possible to observe both a hidden Markov chain and a direct relation between successive observed outputs. Unfortunately, the use of either a visible or a hidden model implies the suppression of one of these hypothesis. This paper prsents a Markovian model under random environment called the Double Chain Markov Model which takes into account the maijn features of both visible and hidden models. Its main purpose is the modeling of non-homogeneous time-series. It is very flexible and can be estimated with traditional methods. The model is applied on a sequence of wind speeds and it appears to model data more successfully than both the usual Markov chains and hidden Markov models.     

Graphical technique for comparing designs for random models

Methods for comparing designs for a random (or mixed) linear model have focused primarily on criteria based on single-valued functions. In general, these functions are difficult to use, because of their complex forms, in addition to their dependence on the model's unknown variance components. In this paper, a graphical approach is presented for comparing designs for random models. The one-way model is used for illustration. The proposed approach is based on using quantiles of an estimator of a function of the variance components. The dependence of these quantiles on the true values of the variance components is depicted by plotting the so-called quantile dispersion graphs (QDGs), which provide a comprehensive picture of the quality of estimation obtained with a given design. The QDGs can therefore be used to compare several candidate designs. Two methods of estimation of variance components are considered, namely analysis of variance and maximum-likelihood estimation.
