The traditional Mestizo view: Implications for modern psychotherapeutic interventions.

Provides mental health professionals with an overview of basic Mestizo tenets. Fundamental issues such as the Mestizo perception of health, the mind–body relationship, metaphysics, and family and community factors are discussed to increase therapeutic sensitivity when working with Mestizos. Suggestions for dealing with these factors are outlined. A holographic model is suggested as a Western-based means of understanding the Mestizo perspective. A holographic paradigm is also recommended as a unifying conceptual model between the 2 divergent world views. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Selective Representing and World-Making

In this paper, we discuss the thesis of selective representing –- the idea that the contents of the mental representations had by organisms are highly constrained by the biological niches within which the organisms evolved. While such a thesis has been defended by several authors elsewhere, our primary concern here is to take up the issue of the compatibility of selective representing and realism. In this paper we hope to show three things. First, that the notion of selective representing is fully consistent with the realist idea of a mind-independent world. Second, that not only are these two consistent, but that the latter (the realist conception of a mind-independent world) provides the most powerful perspective from which to motivate and understand the differing perceptual and cognitive profiles themselves. And third, that the (genuine and important) sense in which organism and environment may together constitute an integrated system of scientific interest poses no additional threat to the realist conception.     

SOC设计复杂性以及IP复用方法

各电子公司正在转向生产采用数字融合技术的产品,这就要求设计者在6~9个月的设计周期内即能提供功能空前复杂的集成电路和片上系统(SystemsonChip,SoC),而且以大批量销售价格供货。这些芯片已经应用于流行的、面向消费者的手持式计算、多媒体和互联网驱动通信产品。SoC设计的复杂性基于SoC概念的设计复杂性,给项目小组带来了巨大的挑战,因为在一个典型系统中将包含众多的功能模块。对于目标系统这样复杂的项目来说,如果要从头设计,即使是人数最多、最有经验而且最为能干的项目团队也是难以胜任的。某种形式的电路知识产权(IP)复用机制已…     

Tunable alexandrite lasers: Development and performance

Some major recent developments in alexandrite laser research are reviewed. Emphasis is placed on key material characteristics, and their relationship to laser performance. Alexandrite's favorable thermomechanical properties and high capacity for energy storage have led to laser performance levels that, in certain areas, exceed those of established solid-state laser sources. Here we review performance achievements for a variety of pulsed and CW laser configurations including single-mode, multimode, and mode-locked resonators, high-power amplifiers, and zig-zag slabs. In these configurations, operating performance levels have been demonstrated that are comparable to those of older, more familiar solid-state laser technologies. Alexandrite's broad tunability offers additional advantages. Together with nonlinear frequency conversion processes, alexandrite lasers provide high-brightness output over most of the UV, visible, and near IR.     

DEBTOR: debt evaluation,bench‐marking and tracking – a water debt management tool to address UK water debt

UK water debt has increased rapidly and has become a significant management issue for most water companies, constraining investment in necessary environmental interventions. Debt is characterised as debt penetration (percentage of customers in debt) and debt intensity (average size of debt per indebted customer). Actual debt characteristics in a water company can be plotted by intensity and penetration to demonstrate performance differences between companies, changes over time and performance relative to national norms. Using the relationships between debt and deprivation, the expected debt performance can be plotted. Using the expected position as a benchmark, the company performance can be evaluated and the remedial strategies can be targeted (if required) towards reduction of frequency and size of debt. The distance between actual and expected values is used as a metric of the requirement for additional debt management investment. Examples of these debtor plots for a range of anonymous companies are presented.
