Ethics and technology design

This article offers a discussion of the connection between technology and values and, specifically, I take a closer look at ethically sound design. In order to bring the discussion into a concrete context, the theory of Value Sensitive Design (VSD) will be the focus point. To illustrate my argument concerning design ethics, the discussion involves a case study of an augmented window, designed by the VSD Research Lab, which has turned out to be a potentially surveillance-enabling technology. I call attention to a “positivist problem” that has to do with the connection between the design context and the use context, which VSD seems to presuppose, and I argue that it is necessary to clearly distinguish between the two, since the designers’ intentions do not always correspond with the users’ practice; in fact, the relation between design and use is very complex and principally unpredictable. Thus, a design theory must accept that foresight is limited to anticipation rather than prediction. To overcome the positivist problem, I suggest a phenomenological approach to technology inspired by Don Ihde’s concept of multistability. This argument, which is general in nature and thus applies to any theory of design ethics, is intended as a constructive criticism, which can hopefully contribute to the further development of design ethics.     

Surveillance,Privacy and the Ethics of Vehicle Safety Communication Technologies

Recent advances in wireless technologies have led to the development of intelligent, in-vehicle safety applications designed to share information about the actions of nearby vehicles, potential road hazards, and ultimately predict dangerous scenarios or imminent collisions. These vehicle safety communication (VSC) technologies rely on the creation of autonomous, self-organizing, wireless communication networks connecting vehicles with roadside infrastructure and with each other. As the technical standards and communication protocols for VSC technologies are still being developed, certain ethical implications of these new information technologies emerge: Coupled with the predicted safety benefits of VSC applications is a potential rise in the ability to surveil a driver engaging in her everyday activities on the public roads. This paper will explore how the introduction of VSC technologies might disrupt the “contextual integrity” of personal information flows in the context of highway travel and threaten one’s “privacy in public.” Since VSC technologies and their related protocols and standards are still in the developmental stage, the paper will conclude by revealing how close attention to the ethical implications of the remaining design decisions can inform and guide designers of VSC technologies to create innovate safety applications that increase public safety, but without compromising the value of one’s privacy in public.

Ethical review and reflexivity in research of children's sexuality

Research in the area of children's sexuality is largely based on observational and retrospective studies. Childhood studies literature increasingly calls upon the inclusion of children's voices, yet with sensitive topics ethical positions often close research possibilities in the territories of children's worlds. Children are perceived as a vulnerable group, especially when the investigation focuses on their sexual development and activity – and it is perceived that this research area is too sensitive and potentially harmful to children. Within the context of beginning a qualitative study on children's sexuality in New Zealand (including interviews with children), this paper reviews a number of studies of childhood research. These studies provide a glimpse at how research focusing on children has been conducted, and explores ethical issues arising in such research. The significance of researcher reflexivity is acknowledged for ethical research practice. The paper concludes that in research on children's sexuality a process of ethical review is limited, and that researcher competence in sensitive investigations is required. Among other difficulties for this researcher (with a professional background in child and family therapy) is the vulnerability of being a man choosing to research children.     

角色冲突视域下我国女性教育的迷茫与出路

我国女性在追求自身解放的过程中产生了强烈的角色冲突与选择困惑,面对这一问题,教育作为控塑女性的重要手段也陷入了迷茫状态而不知何去何从。传统教育有利于培养女性特质,男女都一样的教育有助于女性的自立自强,但却都不能满足女性自身发展的双重需求。当今教育应如何选择发展方向？角色冲突的产生,与公私两大领域的性别化区分存在重要关联。因此,使公共领域与私人领域相融合,实施性另0敏感教育,培养双性共生的“完整人”是当前以及未来女性教育的理性选择。     

Teaching Communication Skills to Medical Students: Unexpected attitudes and outcomes

Experiences in teaching communication skills to medical and veterinary medical students are described. The first involved unexpected attitudes of resentment arising when students took on the role of a patient undergoing a clinical examination. The emergence of empathy as a learning issue due to greater self-awareness was a useful outcome. The second involved resistance to dealing with ethical problems arising during problem-based learning cases. These two emotionally laden attitudes would not have been revealed if more passive traditional ways of teaching had been used. While ability to empathise with another and the ability to deal with difficult interpersonal situations are desirable in the medical professional, there is a paucity of teaching approaches dealing with this aspect of self-development in the undergraduate curriculum. This poses a real challenge to us as facilitators of learning.
