坚持和完善党政联席会议制度 发挥高校院（系）级党组织政治核心作用的思考

院（系）级党组织是教育和团结本单位广大师生员工的政治核心,在学校党组织结构中处于承上启下的关键位置。新修订的高校基层组织工作条例,首次把党政联席会议制度确立为院（系）的工作机制和决策方式。当前,有些高校在落实党政联席会议制度时,还存在着一些问题。因此,必须建立健全党政联席会议的议事决策机制,进一步健全和完善党政联席会议制度,保证院（系）级党组织的政治核心,保证监督作用的有效发挥。     

Recollections of sexual socialisation among marginalised heterosexual black men

This paper describes the sexual socialisation process of marginalised, drug-using heterosexual black men, focusing primarily on the sources and content of sexual information. Analysing qualitative interview data, we discovered that the men in our sample both learn about sex and become sexually active at an early age. They most often learn about sex from the media and least often learn about sex from family members. The content of sexual information varies in specifics, but overall tends to equate sex with pleasure, encourage sexual activity with multiple partners and emphasise using protection. Our goal is to use this data to better understand how sexual socialisation contributes to the prevalence of multiple sexual partners and high rates of HIV among heterosexual black men in order to inform future risk-reduction intervention programmes.

四周常压模拟高住低练对女子赛艇运动员血清睾酮、皮质醇及血睾酮／皮质醇的影响

目的:探讨4周常压模拟高住低练训练法对女子赛艇运动员血清睾酮、皮质醇及血睾酮/皮质醇等的影响。方法:系统观察了7名女子赛艇运动员(实验组)进行4周高住低练(2500m)训练前、训练期间第1周、第2周、第4周及训练后第1周和第2周这些指标的变化,并与6名低住低练运动员(对照组)进行比较分析。结果:(1)4周高住低练使女子赛艇运动员血清T水平呈先降后升之势,4周结束后仍低于实验前水平,并且至少持续2周;(2)4周高住低练期间运动员血清皮质醇水平降低,实验结束后2周恢复到实验前水平;(3)4周高住低练期间Hb和RBC的变化与T和T/C的变化并不一致,实验前后比较,前两者总体趋势是升高,而后两者总体趋势是下降。结论:4周高住低练使血清T水平先降后升,血清C水平降低,这可能与低氧刺激导致血液Hb和RBC逐渐升高以及机体合成代谢相对增强有关。     

网络应用程序的负载平衡问题

在现今网络时代,通过网络寻找信息的需求量越来越大,在网络节点上的服务器需要有相当的负载能力,而且越来越多的情况下还需要通过几台服务器来共同完成对需要的应答任务。介绍了一种多服务器共同负载并平衡工作的技术——负载平衡。首先概要性地描述了负载平衡的原理,并按照软件应用的执行过程,从软件层次至硬件平台,自上而下的顺序将常见的负载平衡方法分为软件级负载平衡、网络级负载平衡、硬件级负载平衡,并简明扼要地说明了各种负载平衡的使用范围、实现代价、可扩展性与及总体优缺点。     

“Students Get What Flows Downward”: District Leaders’ Rationalizations of the Standardized Testing of Children

What do students stand to gain from high-stakes, standardized testing? We consider answers to this question from the perspective of urban district leaders tasked with designing and overseeing the implementation of standardized testing policies. Results revealed variation in leaders’ framing of and rationale for standardized testing with respect to benefits for students and whether/why students should strive for high test scores. Implications for both approaches to standardized testing and broader improvement initiatives are discussed.

Polychlorinated dibenzo-p-dioxins and dibenzofurans in flue gas emissions from municipal solid waste incinerators in China

Polychlorinated dibenzo-p-dioxins and furalls(PCDD/Fs)emissions in flue gas from two types of municipal solid waste incinerators(MSWIs)most commonly used in China were investigated in this study.The selected incinerators include two grate-type MSWIs:MSWl-A(350 t/d)and MSWI-B(150 t/d),and two fluidized bed MSWIs:MSWI-C(400 t/d) and MSWI-D (400 t/d),which are all equipped with semi-dry lime scrubber and bag filter except MSWI-D equipped with cyclone and wet scrubber(WS)as air pollutant conffol device(APCD).Results indicated that the emission concentration and the international toxic equivalents(I-TEQs)of the PCDD/Fs from the stacks were in the range of 1.210～10.273 ng/Nm3 and 0.019～0.201 ngI-TEQ/Nm3,respectively.They were greatly lower than the emission regulation standard of PCDD/FS in China(1.0 ng I-TEQ/Nm3).However,only the PCDD/Fs emission Ievel from MSWI-C Was below 0.1 ng I-TEQ/Nm3.Although the homologue profiles were distinct,the contributions of the 2,3,7,8-subsituted congenem to the total I-TEQ were similar among all the investigated MSWIs.Two major 2,3,7,8-substituted congeners,2,3,4,7,8-PeCDF and 1,2,3,7,8-PeCDD,account for 47% and 9%(average values)of the total I-TEQ values,respectively.The correlation between PCDD/Fs levels and composition of flue gas Was also discussed.

Editorial

This study reports data on the challenges and needs of girls engaged in delinquent behaviour and the effectiveness of services provided by a girls' home. Implications and suggestions for the planning and implementation of effective programmes and services in alternative educational settings are included. It concludes that alternative education is not just a change of educational environment for youths in trouble, an understanding of the unique needs of girls and female offenders must be translated into practice as educators continue to find solutions for helping girls who are engaging in risky or delinquent behaviours.
