The Nature and Value of Sex - A BOOK REVIEW OF: Sex: A Philosophical Primer,Expanded Edition by Irving Singer

Heterosexual and homosexual males who erotically preferred physically mature partners were compared with respect to the erotic impact of the nonpreferred age groups (of the preferred gender) and the nonpreferred gender. Erotic impact was assessed by phallometric test of erotic gender and age preferences. This measures penile volume changes during the presentation of potentially erotic stimuli. Homosexual males who preferred physically mature partners responded no more to male children than heterosexual males who preferred physically mature partners responded to female children. Although heterosexual males showed a (slight) erotic aversion to the male stimuli, and homosexual males did not show an aversion to the female stimuli, this difference was minimal.     

Linearity of the electromechanical penile plethysmograph's output at large expansions

Despite the widespread use of the Barlow‐type electromechanical plethysmograph for monitoring changes in penile circumference, doubts have arisen about its sensitivity at large expansions. This study investigated the linearity of both a used and unused gauge over a wide range of standardized expansions. For both gauges, the relationship between electrical output and physical expansion was almost linear. A logarithmic 10 transformation on the physical expansion data did not for either gauge achieve perfect linearity. Contrary to suggestions in the literature, therefore, such a transformation is not required when using this gauge.     

Effects of tadalafil treatment combined with physical activity in patients with low onset hypogonadism: results from a not-randomized single arm phase 2 study

Purpose: To investigate a possible relation between penile Doppler ultrasound examination (PDUE) parameters and efficacy of chronic therapy with tadalafil (TAD) combined with a protocol of aerobic physical activity (PA) in patients with late onset hypogonadism (LOH). Methods: The study evaluated 30 patients consecutively enrolled with LOH and erectile dysfunction which present contraindication to hormonal replacement therapy for concomitant prostate disease. These patients were subjected to a combined protocol with phosphodiesterase V selective inhibitors (TAD 5?mg daily) and aerobic PA.

Results: After three months, we observed significant improvements in erectile function [IIEF-5, median (IQR)?=?13.0 (7.0–18.0) versus 6.0 (5.0–6.75); p?p?Conclusion: PA in association with phosphodiesterase V inhibitors could compensate the effects of hypogonadism on erectile function and facilitate the clinical response to these drugs even in the absence of adequate serum concentrations of total testosterone.     

4H-SiC离子注入层的欧姆接触的制备(英文)

用氮离子注入的方法制备了4H-SiC欧姆接触层。注入层的离子浓度分布由蒙特卡罗分析软件 TRIM模拟提取,Si面4H-SiC-Ni/Cr合金欧姆接触的特性由传输线方法结构进行了测量,得到氮离子注入层的方块电阻Rsh为30 kW/square, Ni/Cr合金与离子注入层的欧姆接触电阻rc为7.1×10-4 Wcm2。     

“技科学”语境下的后人类之痛——对厄休拉·勒奎因《变化的位面》的技术解读

厄休拉·勒奎因的《变化的位面》以斯威夫特式的艺术想象,虚构了两个过分使用基因技术进行身体修复和身体潜能扩张的故事,再现了当代技科学语境下的＂技术态身体＂现象。借助于基因改造的悲剧,故事展示了基因技术在试图突破人类认知和智力局限的同时,颠覆了＂人类本质＂,并带来了难以逆转的后人类之痛。文章追踪了作者对＂后人类主义＂技术观念的批判,指出该小说警示人类不要毫无顾忌地使用技术打破人类和非人类生命的界限,或无限拓展身体潜能,并强调了人类＂精神性＂对技术灾难的反向平衡作用。     

Sex offenses against female children perpetrated by men who are not pedophiles

Previous research and clinical impression indicate two possible predictors of gynephilic preference among offenders against female children: (1) the occurrence of the offense within a father‐daughter (or stepdaughter) relationship, and (2) victimization of only one child. Validation of these putative predictors was by phallometric test results of a total of 187 male adult subjects: 95 “incest” offenders against female children, 54 such non‐incest offenders, and 38 offenders against adult females. Each of these predictors showed to be valid in its own right, and the interaction of the two did not increase prediction potential.     

高能硅离子注入GaAs的晶格损伤研究

用卢瑟福背散射／沟道技术研究了１ＭｅＶＳｉ￣＋在３５０℃高温和室温下以不同剂量注入ＧａＡｓ后的晶格损伤。在衬底加温注入下，观察到ＣａＡｓ中存在一个动态退火速率与缺陷产生速率相互平衡的剂量范围以及两种速率失去平衡时的临界剂量。用级联碰撞理论分析了所观察到的实验结果。     

对我国商标法植入淡化理论的再思考

伴随着现代商标功能的转变,对于驰名商标的保护也经历了一个从混淆保护到淡化保护的过程。淡化理论本身既具有法理学基础,又符合商品经济的发展趋势,加上美国和欧盟在这方面立法上的成功经验,所以很多学者都认为,此次修改《中华人民共和国商标法》（以下简称《商标法》）修改中应引入此理论。怛综合分析我国国情及驰名商标认定的现状,《商标法》的宗旨与国家知识产权战略要求,目前引入淡化理论还为时过早,不会起到相应的积极作用。建议此次修改中完善驰名商标特殊保护的重点工作还应是进一步加强混淆保护制度,并在此基础上为今后的淡化理论植入做铺垫。     

离子束法合成钛铝,镍铝合金的研究

利用从金属蒸汽真空孤离子源引出的强束流钛、镍离子,进行了钛铝、镍铝合金的合成试验研究。研究结果表明,在一定的注入条件下,钛、镍离子的注入能在铝表面形成相应的合金层,离子注入样品的磨损率比未注入样品的明显降低。借助于卢瑟福背散射和X射线衍射分析,我们发现表面合金层中分别形成了Al3Ti、NiTi及Al2O3相,钛在铝中能产生20％以上的原子百分浓度,其深度高达7000。最后,本文还讨论了磨损率降低的原因。     

高校校内学生申诉制度的法社会学研究——以北京市高校为研究样本

高校校内学生申诉制度于2005年正式实施,教育部的规范性文件对其具有的规范功能予以初步阐述,即化解矛盾、维护权利及维持秩序。各高校根据教育部要求纷纷设立该项制度,但其规范功能在实践中的表现各有不同,体现为其功能是否实现、实现的程度以及该制度是否还发挥其他功能等方面。本文以北京市高校为研究样本,对上述实践情况予以描述、分析和总结,认为国家对高校进行行政规制的方式与程度、高校自治的程度等是影响高校校内学生申诉制度功能的重要因素。
