Background. Current screening instruments for hypogonadism lack adequate specificity and diagnostic accuracy. A new self-administered questionnaire of hypogonadism symptoms is being developed to address this need. The process for questionnaire development and results from the first (qualitative) phase are presented.Methods. Qualitative interviews were conducted based on a new conceptual model of hypogonadism and according to standards for questionnaire development. An item pool was generated from focus groups and in-depth interviews with two groups of hypogonadal patients, treated (N = 26) and untreated (N = 26), and age-equivalent controls (N = 28). Standardized scoring of the qualitative interviews was used to confirm conceptual domains in the model and to generate questionnaire items for further validation.Results. Key domains identified in both patients and controls included: (a) physical function; (b) bodily signs and symptoms; (c) sexual function and libido; (d) sleep function; (e) mood and affective function; (f) memory and cognitive function. The final domain is distress or bother associated with hypogonadism symptoms. This domain was only relevant to the patient groups.Conclusions. The first stage in the design of a new hypogonadism screener has been completed. Seven domains were identified and draft items were developed in each domain according to current standards of patient-reported outcomes. 相似文献

AbstractThis paper discusses the role of the Modified Social Benches, a series of urban artworks, as platforms for bodily engagement and social encounters in open, outdoor urban spaces. Special attention is given to a couple of salient aspects involving both the design of the artworks and their social appropriation: (a) the different levels of sensory and kinesthetic engagement afforded by the benches, and (b) how these material qualities reflect in the urban space around the benches, lending the artworks a notorious social character. The social and the bodily dimensions are presented as intertwined characteristics of the Modified Social Benches. In order to explore these relationships, the paper highlights a set of key concepts, such as social encounters and affordances, as well as the notions of performance and engagement. 相似文献

We introduce extensions of stability selection, a method to stabilise variable selection methods introduced by Meinshausen and Bühlmann (J R Stat Soc 72:417–473, 2010). We propose to apply a base selection method repeatedly to random subsamples of observations and subsets of covariates under scrutiny, and to select covariates based on their selection frequency. We analyse the effects and benefits of these extensions. Our analysis generalizes the theoretical results of Meinshausen and Bühlmann (J R Stat Soc 72:417–473, 2010) from the case of half-samples to subsamples of arbitrary size. We study, in a theoretical manner, the effect of taking random covariate subsets using a simplified score model. Finally we validate these extensions on numerical experiments on both synthetic and real datasets, and compare the obtained results in detail to the original stability selection method. 相似文献

This study examines the prevalence and correlates of psychological abuse and physical abuse against women and men aged 70 or older. Self-report data from 2,185 respondents in the 2010 National Intimate Partner and Sexual Violence Survey (NISVS) were used to create weighted estimates for past-year experiences of abuse. Correlates were then examined using survey logistic regression models. More than 1 in 10 adults who are 70 years of age or older (14.0%) have experienced some form of abuse in the past year, with 12.1% experiencing psychological abuse and 1.7% experiencing physical abuse. One in five victims (20.8%) were abused by both intimate and nonintimate partners. Health care insecurity was the strongest correlate of past-year abuse. The odds of experiencing abuse were 4.53 times greater for those who experienced health care insecurity than for those who did not. This presents a significant challenge for identifying and helping victims of abuse. 相似文献

Drivers of land use change and household determinants of sustainability in smallholder farming systems of Eastern Uganda 总被引:1,自引:0,他引:1

Smallholder farming systems in sub-Saharan Africa have undergone changes in land use, productivity and sustainability. Understanding
of the drivers that have led to changes in land use in these systems and factors that influence the systems’ sustainability
is useful to guide appropriate targeting of intervention strategies for improvement. We studied low input Teso farming systems
in eastern Uganda from 1960 to 2001 in a place-based analysis combined with a comparative analysis of similar low input systems
in southern Mali. This study showed that policy-institutional factors next to population growth have driven land use changes
in the Teso systems, and that nutrient balances of farm households are useful indicators to identify their sustainability.
During the period of analysis, the fraction of land under cultivation increased from 46 to 78%, and communal grazing lands
nearly completely disappeared. Cropping diversified over time; cassava overtook cotton and millet in importance, and rice
emerged as an alternative cash crop. Impacts of political instability, such as the collapse of cotton marketing and land management
institutions, of communal labour arrangements and aggravation of cattle rustling were linked to the changes. Crop productivity
in the farming systems is poor and nutrient balances differed between farm types. Balances of N, P and K were all positive
for larger farms (LF) that had more cattle and derived a larger proportion of their income from off-farm activities, whereas
on the medium farms (MF), small farms with cattle (SF1) and without cattle (SF2) balances were mostly negative. Sustainability
of the farming system is driven by livestock, crop production, labour and access to off-farm income. Building private public
partnerships around market-oriented crops can be an entry point for encouraging investment in use of external nutrient inputs
to boost productivity in such African farming systems. However, intervention strategies should recognise the diversity and
heterogeneity between farms to ensure efficient use of these external inputs. 相似文献

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. 相似文献

AbstractAt 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. 相似文献

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. 相似文献
