„Nanotechnologie“ als neue „Schlüsseltechnologie“?—Versuch eines historischen und systematischen Vergleichs mit anderen Technologien

Nanotechnology seems to be a new “key-discipline”, which should lead to basic changes in many areas of living and producing. This estimation is questioned by a comparison with established technologies, which reach from heat engines to biotechnology. In this line it is possible to come to a more realistically assessment of nanotechnology. “Technologies” in the narrower sense are understood as techniques based scientifically and integrated systematically into a network. The development of these technologies starts first in the early modern times. Before this background the established technologies are characterised looking at relevant questions and problems, the role of researchers and inventors, the importance of theoretical foundations, important applications and innovations, as well as the relevance of visions and then confronted with nanotechnology in its present state. It is accentuated that there are no explicit theories and no specific applications of nanotechnology and it seems to be only a kind of chemical technology.

Children's Road Crossing: A Window Into Perceptual–Motor Development

ABSTRACT— Most research on perceptual–motor development has focused on changes occurring during infancy and toddlerhood. In this paper, we describe our work on the development of perceptual–motor development during late childhood and early adolescence in the context of an important applied problem: bicycling across traffic-filled roads. Specifically, we have examined the gaps between cars that children and adults accept when bicycling across intersections, using an immersive, interactive bicycling simulator. This work highlights both methodological advances in using immersive, interactive virtual environments to study perceptual–motor functioning as well as theoretical advances in understanding the problem of moving the self in relation to other moving objects. We conclude with ideas for future research and practical implications of this work.     

泌尿外科微创技术与临床决策

微创技术在泌尿外科中的应用越来越广泛,对临床决策也产生了深远的影响。临床决策应以最佳证据作指导,充分评价不同方案的风险和利益,选择出最优方案应用于临床实践。微创技术的应用要以人为本,要贯穿诊断和治疗的全过程,要因地制宜,充分考虑应用的物质条件和基础。微创技术的应用也必须考虑经济因素,应选择适宜技术进行适度治疗。     

从辅助生殖技术的个案析要论知情同意的完善

结合在人类辅助生殖技术服务过程中发生的案例进行分析,就如何完善知情同意提出了一些见解。认为,医疗技术服务中,知情同意的完善必须注重两个环节,知情同意过程和签署知情同意书。这两个环节必须根据具体情况来进行实施,绝不能敷衍走过场。因此,相关医生对知情同意的认识和伦理监督就显得尤为重要。     

PARAMETRIC ANALYSIS OF PRESESSION EXPOSURE TO EDIBLE AND NONEDIBLE STIMULI

We assessed the effects of individually defined small, medium, and large periods of presession access to edible and nonedible reinforcers on response rates during sessions in which responding produced access to identical reinforcers. Any presession access to an edible reinforcer decreased response rates for 1 participant, and small and medium periods of presession access to nonedible reinforcers resulted in similar or increased response rates for 2 participants.     

USING MICROSOFT OFFICE EXCEL® 2007 TO CONDUCT GENERALIZED MATCHING ANALYSES

The generalized matching equation is a robust and empirically supported means of analyzing relations between reinforcement and behavior. Unfortunately, no simple task analysis is available to behavior analysts interested in using the matching equation to evaluate data in clinical or applied settings. This technical article presents a task analysis for the use of Microsoft Excel to analyze and plot the generalized matching equation. Using a data‐based case example and a step‐by‐step guide for completing the analysis, these instructions are intended to promote the use of quantitative analyses by researchers with little to no experience in quantitative analyses or the matching law.     

Let’s Make Things Better: A Reply to My Readers

This article is a reply to the three reviews of my book What Things Do: Philosophical Reflections on Technology, Agency, and Design (Verbeek 2005) in this symposium. It discusses the remarks made by the reviewers along five lines. The first is methodological and concerns the question of how to develop a philosophical approach to technology. The second line discusses the philosophical orientation of the book, and the relations between analytic and continental approaches. Third, I will discuss the metaphysical aspects of the book, in particular the nature and value of the non-modernist approach it aims to set out. Fourth, I will discuss the social and political relevance of the book. Fifth, this will bring me to some concluding remarks about how the postphenomenological perspective developed in the book relates to liberalism, focusing on its suggestions to deliberately design our material environment in terms of mediation.

Generalizing Teaching Techniques from University to K-12 Classrooms: Teaching Preservice Teachers to Use What They Learn

Preservice teachers learn evidence-based practices in university classrooms but often fail to use them later on in their own K-12 classrooms. The problem may be a missing link in teacher preparation, i.e., failure to teach preservice teachers to generalize newly acquired techniques. Two experiments using multiple baseline designs across participants assessed effectiveness of a model to promote generalization and maintenance of a specific teaching skill. In Experiment 1, preservice teachers’ maintenance of behavior deteriorated from practicum to student teaching when intervention consisted of training to criteria alone. When a programming for generalization component (program common stimuli) was added to the intervention, teachers in Experiment 2 generalized and maintained behavior across settings (student teaching to own classrooms) at a higher average than occurred during intervention.     

Nano-ethics as NEST-ethics: Patterns of Moral Argumentation About New and Emerging Science and Technology

There might not be a specific nano-ethics, but there definitely is an ethics of new & emerging science and technology (NEST), with characteristic tropes and patterns of moral argumentation. Ethical discussion in and around nanoscience and technology reflects such NEST-ethics. We offer an inventory of the arguments, and show patterns in their evolution, in arenas full of proponents and opponents. We also show that there are some nano-specific issues: in how size matters, and when agency is delegated to smart devices. Our overall approach is a pragmatist ethics, and we conclude that struggle (and learning) might be more productive than models emphasizing consensus.

Building an active citizenry: the role of neighborhood problems, readiness, and capacity for change

Community-building initiatives strive to involve residents as the drivers of the change process, involving them in an array of activities including collective action efforts. Recent evaluations of many of these initiatives, however, suggest that developing the levels of resident involvement needed in such efforts is challenging. This study examines the neighborhood conditions that are related to whether and how much residents become involved in individual activism and collective action efforts. A random-digit-dial phone survey of 460 residents in 7 distressed neighborhoods suggested that while demographic variables were relatively unimportant, resident perceptions of neighborhood readiness (i.e., hope for the future and collective efficacy) and capacity for change (i.e., social ties and neighborhood leadership), and the level of neighborhood problems were strongly related to whether and how much residents were involved in individual and collective action efforts. Moreover, different elements of these neighborhood conditions were more or less important depending on the type and level of resident involvement. For example, while perceptions of neighborhood problems was the strongest predictor of whether an individual became involved at all, perceived strength of neighborhood leadership was the strongest predictor of an individual's level of activity. The implications of these findings for practitioners and scientists are discussed.
