我国建筑涂料产品质量现状分类解析

近年来,建筑业作为国民经济新的增长点得到了突飞猛进的发展,因此各种建筑装饰材料也随之应运而生。我国建筑涂料按其用途分类可分为:内墙涂料、外墙涂料、防水涂料及其它涂料。目前国内水性内墙涂料主要有两类,一类是聚乙烯醇水玻璃以及在此基础上进行各种改进的低档水溶性内墙涂料;另一类是各种中、高档的合成树脂乳液     

彩砂涂料的制备与应用

我国习惯使用的外墙涂料过氯乙烯、聚乙烯醇缩丁醛等在使用中存在的主要问题是:装饰质感比较平淡;易褪色变色;耐久性不够理想。国外建筑涂料品种中粗骨料涂料的发展十分迅速。 彩砂涂料是粗骨料涂料的一种。研制彩砂涂料的目的,一是解决涂料褪色、变色问题;二是从耐久性和装饰效果方面提供一类中、高档建筑涂料。采砂涂料从研制着色骨料入手,用着色骨料代替一般涂料中

Intra-metropolitan shifts in labor demand and the adjustment of local markets

I offer new evidence on the adjustment of local labor markets to geographic shifts in labor demand within US metropolitan areas using a unique data set in which metropolitan subregions are geographically matched across the 1970–1980 and 1980–1990 decades. The evidence uncovered paints the following picture. Workers, especially those with less education, make incomplete adjustments within metropolitan areas in response to intra-metropolitan demand shifts. Although blacks may not make especially limited adjustments, they have disproportionately suffered deleterious effects from job movements because the demand shifts have tended to be away from their places of residence.     

Current issues and future directions in simulation-based training in North America

A number of emerging challenges including globalization, economic pressures and the changing nature of work has combined to create a business environment that demands innovative, flexible training solutions. Simulations are a promising tool for creating more realistic, experiential learning environments to meet these challenges. Unfortunately, the current literature on simulation-based training paints a mixed picture as to the effectiveness of simulations as training tools, with most of the previous research focusing on the specific technologies used in simulation design and little theory-based research focusing on the instructional capabilities or learning processes underlying these technologies. This article examines the promise and perils of simulation-based training, reviews research that has examined the effectiveness of simulations as training tools, identifies pressing research needs, and presents an agenda for future theory-driven research aimed at addressing those needs.     

Reframing human resource management in Africa: a cross-cultural perspective

Current approaches to understanding the management of people in Africa are often framed within a pejorative 'developing/developed' world paradigm that not only paints a negative view of management in Africa, but also assumes the need to develop towards the 'developed' world approach. Cross-cultural analysis that focuses first on historical and current cultural interaction across continents suggests a difference between an instrumental view of people as a resource to serve the ends of the organization and a humanistic view which sees people as having a value in themselves. This offers a more useful paradigm for progressing both research and practice in this area. Both a conceptual model and a typology of management systems are offered as a way forward. Research should also focus on cross-cultural difference and interactions at cross-national and interethnic levels. This will facilitate a cross-cultural approach to management development and team building through developing synergies in organizations in Africa     

User knowledge transformation through design: A historical materialism perspective

Through observation of an accounting system development project, this study examines how user knowledge of work, organization, and information system is transformed. The study employs the framework of historical materialism to explicate the interplay of knowledge and material conditions. The findings suggest that contradictions within the material condition, both in the resulting designs and in relations between users and developers, engender crises and trigger alteration of existing knowledge, and that new knowledge is created and validated through negotiating and specifying material designs. Knowledge transformation is shown to be historical in that knowledge is based on material condition at a certain moment and therefore is subject to change due to contradictions in the material condition. Therefore, often knowledge is transformed only partially as users and developers settle on a design to replicate existing practices with new features designed for different practices, producing contradictions for further transformation. The historical interplay of knowledge and material conditions paints a holistic picture of knowledge transformation through information system design.

NIT picking: The macroeconomic effects of a Negative Income Tax

I study a revenue-neutral reform of the U.S. income tax and welfare system that involves the adoption of a Negative Income Tax (NIT). The reform is undertaken in a life-cycle economy with individual heterogeneity and uninsurable idiosyncratic labor risk. The optimal NIT consists of a 22% rate and a transfer equivalent to 11% of per-capita GDP. The ex-ante average welfare gain is a 2.1% annual increase of individual consumption. I show that a NIT outperforms a flat tax reform (income tax plus deduction) by a considerable margin. The key consequence of the reform is that high-productivity agents increase their relative importance in the labor supply at the expense of low-productivity agents.
