It’s Not Me,It’s You: Perceptions of Partner Body Image Preferences Associated With Eating Disorder Symptoms in Gay and Heterosexual Men

This study explored perceptions of partner body image preferences and symptoms of disordered eating in gay and heterosexual men. Participants were male college students (n = 201; M age = 20.46), and over one third identified as gay. We compared discrepancies between participants’ current and ideal body type and participants’ current body type and the body type they believed they should have to attract a dating partner. For gay men, the discrepancy between their current body and the body they believed they should have to attract a dating partner was significantly greater than the discrepancy between their current and ideal body types. In gay and heterosexual men, the discrepancy between current body and the body they believed they should have to attract a dating partner predicted eating, shape, and weight concern. Results suggest that perceptions of partner body image preferences may contribute to eating disorder pathology in men.     

Prevalence analysis of urinary incontinence after radical prostatectomy and influential preoperative factors in a single institution

Aims: To assess prevalence of urinary incontinence (UI) after radical prostatectomy (RP) and to analyze which preoperative characteristics of the patients have influence on UI.

Methods: Between 2002 and 2012, 746 consecutive patients underwent RP for clinically localized prostate cancer. We defined UI according to International Continence Society (ICS) definition: “the complaint of any involuntary leakage of urine” after 12?months of recovery, international consultation on incontinence questionnaire (ICIQ-SF) and pads/day was collected too. Clinical features and magnetic resonance imaging measurements were assessed. A multivariable logistic regression model predicting incontinence were built-in after adjust by cofounding factors and bootstrapping.

Results: About 172 (23%) of the patients were classified as incontinent according to the ICS definition. The mean value of the ICIQ-SF was 10.87 (±4). 17.8% of patients use at least one pad/day, 11.9% use more than one pad/day. The preoperative factors independently influential in UI are: age [OR: 1.055; CI 95% (1.006–1.107), p?=?.028], urethral wall thickness [OR: 5.03; CI 95% (1.11–22.8), p?=?.036], history of transurethral resection of the prostate [OR: 6.13; CI 95% (1.86–20.18), p?=?.003] and membranous urethral length [OR: 0.173; CI 95% (0.046–0.64), p?=?.009]. The predictive accuracy of the model is 78.7% and the area under the curve (AUC) value 71.7%.

Conclusions: Urinary incontinence after radical prostatectomy has different prevalence depending on the definition. Age, prior transurethral resection of the prostate (TURP), membranous urethral length (MUL) and urethral wall thickness (UWT) were risk factors.     

Same-Sex Attracted,Not LGBQ: The Associations of Sexual Identity Labeling on Religiousness,Sexuality, and Health Among Mormons

ABSTRACT

In the Church of Jesus Christ of Latter-Day Saints (LDS church), beliefs about same-sex sexual attraction are carefully differentiated from beliefs about same-sex sexual behavior and identity, leading some to reject a lesbian, gay, bisexual, or queer (LGBQ) identity label in favor of declining a sexual identity or describing themselves as experiencing same-sex attraction (SSA). Using data from 1,128 sexual minority Mormons recruited from both politically conservative and liberal circles, we examined the relationship between rejecting an LGBQ identity and religiousness, attitudes toward sexuality, and health outcomes. We found that Mormons who reject an LGBQ identity were significantly more religious and less content with their sexuality but had similar health outcomes relative to LGBQ Mormons. We posit that these differences are best understood by differences in group affiliation and support, intersectional experiences with minority stressors, and the lack of generalizability of LGBQ constructs to those who reject an LGBQ identity.     

扬州市旅游景区空间结构优化整合策略研究

旅游空间结构对区域旅游的发展具有重要意义。应用最邻近距离指数、基尼系数、通达度指数3种分析方法,使用Mapinfo软件对扬州市3A级以上景区的空间结构进行分析,结果表明扬州市3A级以上景区在空间上呈集聚分布状态,均匀程度较低;景点间移动的难度较小,可进入性较高。在探讨影响扬州旅游景区空间结构的主要因素前提下,提出了扬州市旅游景区空间结构优化整合的若干策略。     

低碳出行下轨道交通对景点可达性的影响——基于社会网络分析法

旅游景点的可达性是城市提升“交通+旅游”融合发展中的关键问题,在交通可达时间测算基础上引入社会网络分析法,基于ArcGIS和ucinet 6软件构建景点可达网络,并测算景点网络密度、度中心性、居中中心性、核心-边缘结构等网络技术指标,探讨散客化背景下低碳出行中轨道交通对西安市A级及以上景点网络中各节点的交通可达性及其在景点网络中的地位、角色的影响,通过不同指标的计算,分析景点直接和间接可达性及其变化情况。研究表明:西安市轨道交通重点提升了主城区及周边偏远地区地铁沿线局部网络及单个景点的可达性,“地铁+公交+骑行”使景点网络的核心-边缘分区结构呈现逐渐弱化的趋势,地铁沿线逐渐形成新的景点网络“旅游走廊”; 西安市轨道交通有效衔接了中西部、中北部偏远景点间的联动,对于局部景点网络中的景点资源有效分配及组合发展具有有效调整作用。未来的公共交通网络、枢纽站建设应重点考虑度中心性高的景点及核心区景点,受地铁优化较小的景点应转向探索发展景点旅游直通车; 应重点针对居中中心性高、同个凝聚子群的景点规划建设特色旅游线路; 公共交通与景点应互为宣传,突出并强调景点公共交通可达的便捷性。

Bayesian analysis of dynamic magnetic resonance breast images

Summary.  We describe an integrated methodology for analysing dynamic magnetic resonance images of the breast. The problems that motivate this methodology arise from a collaborative study with a tumour institute. The methods are developed within the Bayesian framework and comprise image restoration and classification steps. Two different approaches are proposed for the restoration. Bayesian inference is performed by means of Markov chain Monte Carlo algorithms. We make use of a Metropolis algorithm with a specially chosen proposal distribution that performs better than more commonly used proposals. The classification step is based on a few attribute images yielded by the restoration step that describe the essential features of the contrast agent variation over time. Procedures for hyperparameter estimation are provided, so making our method automatic. The results show the potential of the methodology to extract useful information from acquired dynamic magnetic resonance imaging data about tumour morphology and internal pathophysiological features.
