Foreign Women and Toilets

This article considers representations of migrant women who work as domestic help and probes the abjecting logic of cleaning practices vis-à-vis current issues of legality, illegality, immigration, transcultural difference, and rage. I survey diverse media depictions of foreign women and cleaning scenes in transnational settings: Fear and Trembling (2003), Maid in America (2004), The Ukrainian Cleaning Lady (2002 The Ukrainian Cleaning Lady (Pani Z Ukrainy) (documentary) (2002) Pawe? ?oziński (dir.), Poland [Google Scholar]), Dirt (2003 Dirt (film) (2003) Nancy Savoca (dir.), USA [Google Scholar]), and Friends with Money (2006). I examine the formation and apprehension of female “foreign” subjectivity in relation to cleaning for others, in relation to dirt. The visual analysis discusses ways in which removing other people's dirt by an immigrant, migrant, or a guest worker intertwines with gendered and racialized processes of social abjection. Privileging images of toilets and expressions of rage, my analysis inquires into a conceptual correspondence between garbage and the cultural renditions of foreign others; into ways in which the concept of “dirt” gets transposed onto the cleaners suggesting that those who clean dirt are themselves disposable bodies, only useful and tolerable as long as they cohere the messy lives of “legitimate” and properly “clean” natives.     

CDM在河北省秸秆发电项目中的应用研究

河北省是一个农业大省,每年秸秆产量十分可观.通过分析河北省晋州24MW秸秆发电项目,估算出河北省秸秆发电项目经核证的减排量(CERs)的收益;并分析了秸秆发电发展所面临的一系列障碍.若将此类项目开发成为CDM项目,将有助于克服这些障碍.     

长输管线清洗研究与应用

对卞杨长输管线污垢类型进行分析,并从化学清洗方法的角度对清洗剂的组成作了讨论。室内实验结果表明:低浓度无机酸—盐酸对污垢有较好的清洗能力;酸液浓度,清洗温度等对清洗有很大影响;清洗剂中氧化剂的添加可有效控制有害气体—硫化氢的生成。     

高压水射流与机械联合作用处理堵塞油管

在油田开发过程水泥浆堵塞油管现象时有发生。传统的处理方法是将这些堵塞的油管报废,结果造成很大的浪费。在系统研究高压水射流流动规律和动力特性基础上,深入分析了水力与机械联合破岩机理,根据不同使用条件和适用对象,对水射流参数进行了调整,对钻头切削齿和喷嘴布置进行合理的设计。首创了一种高压水射流处理水泥堵塞油管新技术,设计制造了清洗堵塞油管专用设备和工具,现场实验取得了突破性进展。     

从“打扫干净屋子再请客”看中美关系的改善与发展

新中国成立前夕 ,以毛泽东为代表的中国共产党人对历史和现实及国际环境进行了深刻思考 ,提出了“打扫干净屋子再请客”的外交政策。这一政策是毛泽东外交智慧的充分体现 ,它对中美关系的改善、发展以至建交产生了重大影响     

长齿条的加工工艺分析

长齿条由于尺寸太长而无法在通用设备上加工,改装有车齿装置的C630-Ⅱ型车床可同时加工几十根齿条;X63型铣床采用专用铣头后也可加工,两者有不同的优缺点,决定了不同的使用场合.     

可扩展数据清理软件平台的研究

提出一种可扩展的数据清理软件平台,该软件平台具有开放的规则库和算法库,规则库用来存放清理规则,算法库用来存放清理算法,算法库中包含多种算法,并可对其扩展;通过在规则库中定义清理规则以及从算法库中选择合适的清理算法,可使该软件平台适用于不同的数据源,从而使其具有较强的通用性和适应性;通过多种算法的清理,提高了数据清理的综合效果。最后,通过实例验证了该平台的效果及可行性。     

凉山彝族冷兵器的种类和形制研究

凉山彝族自治州是我国最大的彝族聚居区,凉山彝族冷兵器包括矛、镗、长刀、短刀、匕首、檑木、稽石、弓箭、盔甲、盾牌等,且数量众多。从形制上分析,式样繁杂、形制独特,民族文化内涵丰富。极具民族特色和研究价值。     

Swimming Pool Hygiene: Self-Monitoring,Task Clarification,and Performance Feedback Increase Lifeguard Cleaning Behaviors

The effects of task clarification, self-monitoring, and performance feedback on cleaning behaviors of 9 lifeguards in 3 performance areas (vacuuming, lobby tidying, and pool deck maintenance) were investigated using an ABA reversal design at a county swim complex. A specific task in each performance area was used as a behavioral control. Following a task clarification meeting, the percentage of closing tasks completed each night was self-monitored through ratings by lifeguards and managers. Researchers conducted independent ratings of these completed tasks after the staff had left the building. Feedback data were posted daily using line graphs that displayed the percentage of tasks completed correctly from both self-report and researchers' data. Overall performance increased from an average of 45.1% correct behaviors during baseline to an average of 76.9% during intervention then reversed to baseline during follow-up to an average performance of 45.05%.     

20世纪学术史背景下的陈寅恪、唐长孺和胡如雷

朱雷通过回顾唐长孺领导敦煌吐鲁番文书整理出版的整个过程,介绍了古代文献资料整理的特点和规律。张国刚认为,在中国20世纪学术发展的宏观走向上,出现了一个从否定传统到呼唤回归本土化的历史演变过程,而在这一变化过程中,陈寅恪、唐长孺、胡如雷都做出了各自的探索。冻国栋从社会经济史的角度,探讨了唐长孺在中古史研究方面的取得的突出成就,对唐长孺的治学理路和特点作出了准确概括。宁志新和黄正建侧重分析了胡如雷在历史研究中所运用的阶级与阶层分析方法,并对这一治学方法做出了客观和科学的评价。孙继民在20世纪学术史的背景下,从20 世纪中国史学发展的四个阶段分析和确认了陈寅恪、唐长孺、胡如雷史学研究成就和他们在中国学术史上的地位。认为陈寅恪的特点是承旧启新,文化史观中国化;唐长孺是转旧趋新,唯物史观学术化;胡如雷是弃旧开新,古史形态理论化。
