Review of Interviewing in Social Research.

Reviews the book Interviewing in social research by H. H. Hyman et al. (1954). This volume is a scholarly but freeflowing treatise on sources of error and potentialities for their control in the survey interview. The book is divided into seven rather lengthy chapters. Chapter I, entitled "A Frame of Reference for the Study of Interviewer Effects," reviews the widespread application of interviewing as a fallible method of scientific inquiry, and cautiously suggests the possibilities for generalization about other kinds of interviewing from studies of the survey interview. Chapter II, "The Definition of the Interview Situation," is devoted to the formulation of hypotheses about factors affecting interviewing from "phenomenological" case studies based largely on intensive interviews with interviewers and respondents. The third chapter presents an analysis of "Sources of Effect Deriving from the Interviewer." Chapter IV, "Respondent Reaction in the Interview Situation," reviews the contradictory evidence on personal interviewing vs. self-administered questionnaires. The "Situational Determinants of Interviewer Effects" are examined in Chapter V. Chapter VI is an attempt to evaluate the magnitude of "Interviewer Effects under Normal Operating Conditions." The final chapter is devoted to consideration of the relative merits of various methods for "Reduction and Control of Error." (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Informal settlement upgrading in South Africa: beneficiaries’ perceptions over nearly twenty-five years

Research on informal settlement upgrading tends to focus on one-off case studies. This article investigates the changing experiences, over nearly 25 years, of people living in an upgraded informal settlement. We sought to determine how the perceptions of the residents of Freedom Square changed. Our latest survey (2014) included responses from 199 household representatives and followed earlier surveys. Firstly, we find that the upgrading of Freedom Square represents a first step towards ensuring the housing rights of black people in urban South Africa. Secondly, spatial infilling and locational advantage continue to play valuable roles. Thirdly, dweller control, in terms of which residents themselves are able to design extensions to their houses, remains important. Fourthly, social cohesion among community members is proving to be more important than access to a stand. Fifthly, urban management remains an important long-term requirement. Lastly, elements of informality persist in the area.     

Review of Behavior Modification: What It Is And How To Do It (Second Edition).

Reviews the book, Behavior Modification: What It Is And How To Do It (Second Edition) by Garry Martin and Joseph Pear. Behavior Modification: What It Is And How To Do It is a very accurate title. The text is not a survey of the many different kinds of problems to which behavioural technology has been applied. Rather, it teaches the basic concepts of operant and respondent behaviour within the confines of specific areas of application with children and adults. The reviewer highly recommends Behavior Modification: What It Is And How To Do It as an excellent, rigorous, flexible, and reportedly very readable text for both undergraduate and graduate student courses for which the content is appropriate. I would hope, however, that the authors would consider offering a test bank of multiple-choice questions (preferably on microcomputer diskettes, which are becoming increasingly common) so that the text could be more easily adapted to Mastery Learning techniques which do require very frequent examinations. An already excellent textbook, with this additional capability, could make what is now a significant contribution into a classic contribution to the teaching of the concepts and techniques of behaviour analysis!

Review of Behavior modification: What it is and how to do it (Second edition).

Reviews the book, Behavior Modification: What It Is and How To Do It (Second Edition) by Garry Martin and Joseph Pear (1983). Behaviour modification procedures now comprise a sophisticated technology, the humane application of which is the subject of Martin and Pear's text, now in its second edition. The intended readership is (1) university students taking courses in behaviour modification and (2) practitioners or students of the various helping professions, a group difficult to aim at because of their varied backgrounds. Topics covered span the range from basic operant and respondent conditioning principles to cognitive therapies. Martin and Pear have succeeded in producing a fine text. Their judgment about amount of detail and illustration is for the most part excellent. Throughout they stress concern for humane, systematic, and ethically conscious treatment. Provided your applications are primarily operant, this, in my estimation, is the best book available from which to teach behaviour modification.

构建了一种镀有陶瓷薄膜的蓝宝石光纤为传感器的瞬态高温测试系统。系统包括蓝宝石高温光纤、锥形高温光纤、耦合器、传输光纤及光电探测器件。基于Plank黑体辐射定律,分析了系统工作原理,并以MATLAB进行了仿真研究。将已标定过的高温钨铼热电偶(测温度范围为1000～2000℃)和蓝宝石光纤温度传感器同时置于乙炔焰热源所形成的恒温区域中进行静态标定,结果表明,测量范围从1200℃到2000℃,测量不确定度(精度)为1℃。以脉冲CO2激光器输出阶跃热信号为动态激励源,获得温度传感器的动态响应曲线,其时间响应达30ms,并且重复性非常好。运动乙炔焰模拟测试结果表明,高温测试范围可达2000℃,可用来对兵器及国防工业等诸多涉及燃烧和爆炸等过程的瞬态温度进行测试。     

外加电场对Cu-Zn-Al合金中类流态胞区响应特征的影响

利用金相显微镜观察了电场对Cu-Zn-Al合金中类流态胞区响应特征的影响。在试样两端施加弱的直流电场后,发现类流态胞区及其周围的亮度和形状产生了变化。实验中拍摄了数十张照片,记下了胞区的变化过程。对该试样进行了扫描电镜及电子探针能谱分析,发现类流态胞区的铜含量比基体少,铝、锌含量比基体多,表明类流态胞区在电场作用下存在质量与能量的迁移和扩散过程。通过计算分形维数,发现类流态胞区具有分形特征并且分形维数值随时间延长而振荡变化。利用电场对材料中晶格缺陷的作用讨论了电场对类流态胞区响应特征的影响。
