Box's paper helicopter has been used to teach experimental design for more than a decade. It is simple, inexpensive, and provides real data for an involved, multifactor experiment. Unfortunately it can also further an all-too-common practice that Professor Box himself has repeatedly cautioned against, namely ignoring the fundamental science while rushing to solve problems that may not be sufficiently understood. Often this slighting of the science so as to get on with the statistics is justified by referring to Box's oft-quoted maxim that “All models are wrong, however some are useful.” Nevertheless, what is equally true, to paraphrase both Professor Box and George Orwell, is that “All models are wrong, but some are more wrong than others.” To experiment effectively it is necessary to understand the relevant science so as to distinguish between what is usefully wrong, and what is dangerously wrong.

This article presents an improved analysis of Box's helicopter problem relying on statistical and engineering knowledge and shows that this leads to an enhanced paper helicopter, requiring fewer experimental trails and achieving superior performance. In fact, of the 20 experimental trials run for validation—10 each of the proposed aerodynamic design and the conventional full factorial optimum—the longest 10 flight times all belong to the aerodynamic optimum, while the shortest 10 all belong to the conventional full factorial optimum. I further discuss how ancillary engineering knowledge can be incorporated into thinking about—and teaching—experimental design.     

中国高等教育与经济发展的区域协调性

 本文应用因子分析法对我国分地区高等教育与经济发展水平的协调性进行了实证分析。利用31个省区市2006年横截面数据计算了各地高等教育与经济发展的因子得分,进行排序、等级差和相关性分析。研究表明：31个省区市中,高等教育与经济发展协调程度为好和较好的有12个,差和较差的有13个,协调程度一般的有6个,总体协调程度较差。在分析个案原因的基础上,提出高等教育发展规划要更多考虑地方经济发展状况和潜力;鼓励高等教育发展滞后地区的地方政府加大对高等教育投资,支持社会资本进入高等教育领域;适当控制发展过度地区的高等教育规模,并加大中央财政对西部欠发达地区的财政支持。     

新中国成立初期干部理论教育制度化建设及经验探析

中国共产党重视干部理论教育,也注重干部理论教育的制度化建设。1949—1956年中国共产党既继承过去干部理论教育制度化建设的做法,又根据新形势、新情况进一步加强干部理论教育建设,完善干部理论教育制度。不断规范干部理论教育的组织体系、教育内容、教育方式、师资培养和考核等,使干部理论教育制度建设不断科学化、规范化,干部的素质和能力得到了较大的提高,为新生政权的巩固和发展起到了重要的作用。这一时期的干部理论教育制度化建设也形成了诸多基本经验,对新时代干部理论教育制度化建设有重要的启示作用。     

Open spaces for dialogue promoting mental health as a social work education methodology

ABSTRACT

The authors discuss service user involvement as a key approach regarding training of social workers. In many European Union countries this is a stable practice with a lengthy tradition in research and application. However, in Poland it is almost entirely absent and marginalized. This article presents the results of a participatory action research project conducted at the Institute of Sociology of the Jagiellonian University in Krakow, the objective of which was to identify and critically analyze the key substantive and formal aspects of training of social workers with the participation of individuals with experience of mental illness. This research project adopted an open approach to cognizing reality based on qualitative co-participatory methods. In the conclusion, the authors emphasize that the fundamental criterion for the success of this particular form of training is voluntary and differentiated participation of students—both in the role of people sharing their own experience and as learners—as well as shaping a culture of open dialogue, educational alliances of recognition and recovery, the foundation of which is axiological experience.     

Interactive Hazards Education Program for Youth in a Low SES Community: A Quasi‐Experimental Pilot Study

A pilot study of an interactive hazards education program was carried out in Canberra (Australia), with direct input from youth participants. Effects were evaluated in relation to youths’ interest in disasters, motivation to prepare, risk awareness, knowledge indicators, perceived preparedness levels, planning and practice for emergencies, and fear and anxiety indicators. Parents also provided ratings, including of actual home‐based preparedness activities. Using a single group pretest‐posttest with benchmarking design, a sample of 20 youths and their parents from a low SES community participated. Findings indicated beneficial changes on a number of indicators. Preparedness indicators increased significantly from pre‐ to posttest on both youth (p < 0.01) and parent ratings (p < 0.01). Parent ratings reflected an increase of just under six home‐based preparedness activities. Youth knowledge about disaster mitigation also was seen to increase significantly (p < 0.001), increasing 39% from pretest levels. While personalized risk perceptions significantly increased (p < 0.01), anxiety and worry levels were seen either not to change (generalized anxiety, p > 0.05) or to reduce between pre‐ and posttest (hazards‐specific fears, worry, and distress, ps ranged from p < 0.05 to < 0.001). In terms of predictors of preparedness, a number of variables were found to predict posttest preparedness levels, including information searching done by participants between education sessions. These pilot findings are the first to reflect quasi‐experimental outcomes for a youth hazards education program carried out in a setting other than a school that focused on a sample of youth from a low SES community.     

Designing for “touch”, “reach” and “movement” in postwar (1946–1972) English primary and infant school environments

ABSTRACT

This article examines the use and interpretation of the terms “touch”, “reach” and “movement” in Ministry of Education (later, Department of Education) official publications known as Building Bulletins between the years 1949–1972. A close critical reading of Building Bulletins concerned primarily with school design for young children (infant and primary schools) in the English context has been carried out and the results of this exercise are discussed in the wider context of close relationships established between architects designing schools and leading progressive educationalists in Britain. The wider international context, particularly progressive educational design in the USA, is used to further understand the use and interpretation of these terms. The article contributes to a current interest among historians of education in exploring material and sensory histories of schooling.
