Economic humidity control: an alternative to reheat

Heat pipe technology will have a significant impact on the power consumption of many manufacturing industries, the installation costs of new or replacement air conditioning systems, and on electric utility peak demands.     

迈哈密大学商学院让退货产生利润

近年来,市场竞争压力迫使许多厂商不断放宽退货规定,哪怕产品没有问题,仅是消费者后悔购买,厂商也欣然接受退货。     

The U.S. immigration crisis

A review of the factors affecting immigration to the United States is presented. The authors develop the argument that present levels of immigration, particularly illegal immigration, are detrimental to U.S. interests, and that current global population trends will make this situation progressively worse. Stricter controls on immigration are considered.     

欧盟的“七年计划”为何不完美

市场的计划是说明性的,不是处方式的不论遵循哪种意识形态,在应对当今政治经济和经济政策时,不能放弃计划这个工具。计划决定着时间和空间上的未来。我所说的计划,不是依照行政目标对资源进行强行再分配,这种对生产方式的干涉模式已经消失在历史中。但是计划并不只有一面。如今,在许多中东欧国家的大学里,已经见不到曾经的计划部门。而在许多公司,都会设立一个专门的计划部门。     

Spotlight on free beds

What happens in today's hospitals when keeping the faith with donors clashes with fiscal politics? An enterprising assistant attorney general asked that question and turned up some disquieting answers.     

翻边机上夹紧油缸弯曲受力分析

二步法旋压机包含翻边机、压鼓机。通常封头厂希望翻边机(在设备规格确定的条件下)能加工厚的封头,同时要求加工封头最小直径,这二者之间很多时候是矛盾的,所以如何配置的上夹紧油缸外径最小,是加工封头最小直径的关键。     

企业文化与人力资源管理关系研究

企业文化影响着人力资源管理活动,对企业核心竞争力有着持久的影响。进行人力资源管理,要充分考虑企业文化对员工的作用。本文根据我国的国情,研究企业文化与人力资源管理之间的关系,研究企业文化如何作用于人力资源管理,以及人力资源如何对企业文化产生作用。通过深入的研究明晰企业文化与人力资源管理的相互影响途径、特征和规律,以求对实际人力资源管理工作有所启发。     

地区一体化是全球化最好机遇

用计算机同时解决多个方程式已经易如反掌,可现实中如果要解决超出国家层面的收入和资源再分配问题,即便使用最聪明的理论也是难上加难.关于在民主国家中解决超越民族国家边界的经济问题是多么步履维艰,欧债危机为此提供了最好的例证:一方面要避免在自己的国家失去支持度;一方面只有帮助其他国家才有连任的希望,同时即便帮助了,仍然有人恶语相加,这一切将有多么困难.一个人怎么可能同时成为国内的叛徒和躲在看不见摸不到之处、却在心理和政治上存在的边界外的吸血鬼?     

A child health production function estimated from longitudinal data. Cebu Study Team

Collaborating researchers used a multi equation model to analyze 3080 mother-infant pairs living on the island of Cebu in the central Philippines and to estimate a child health production function. The econometric methods used eliminated obstacles such as heterogeneity and endogeneity of significant explanatory factors. They also maximized the longitudinal quality of the data. The results showed that morbidity in 1 period reduced infant weight in following periods. For example, diarrhea and febrile respiratory infection reduced growth in the time period following the illnesses. Further effects of some contributing factors were great near birth not diminished with age. For example, breast feeding promoted growth and protected against infection, especially diarrhea and febrile respiratory infection, more substantially near birth than it did later. Further, in urban areas, preventive health care positively affected growth independently of its indirect influence on reducing respiratory infection. Yet it had little effect on diarrhea. Diarrhea had a strong adverse effect on growth. Exposure of the infant to enteric pathogens had the greatest influence on production of diarrhea. In urban areas, exposure included water supply contamination, exposure to feces, a more pathogenic diet, and community crowding. In rural areas, however, exposure included community crowding and increased rainfall which presumably washed feces into the water supply. Household crowding in both urban and rural areas and irritation from smoke in urban areas only tended to bring about febrile respiratory infection.
