辅助生殖技术随访工作中的伦理原则探讨

随着人类辅助生殖技术 (assisted reproductive technology, ART) 的发展, 术后进行的定期随访工作在ART中的伦理学问题不断凸显, 有必要对其重视及规范。从伦理原则角度探讨了ART随访工作中存在的诸多伦理学问题, 即个人隐私权保护的缺失、知情同意的形式化、医源性多胎的伦理困境等。保密互盲、知情同意、保护患者、保护后代等伦理原则监督和规范ART近期及远期随访工作, 对于引导人类辅助生殖技术健康发展, 具有重大现实意义。     

Measuring information demand of a dynamic in-vehicle display while driving – A study evaluating the MARS (Masking Action Relevant Stimuli) method

The MARS (Masking Action Relevant Stimuli) method assesses information demand for dynamic stimuli while driving. An action relevant stimulus is masked and the driver presses a button to unmask the stimulus for a limited period. We interpreted button presses as information demand. Following our previous research (Rittger, Kiesel, Schmidt, & Maag, 2014), the current study further evaluates the method. We applied the MARS method to a dynamic in-vehicle display containing recommendations from a traffic light assistant. In a driving simulator, drivers approached intersections with different traffic light phasing. The display either presented simple or complex information. In half of the drives, the participants used the MARS method. The study had a full within subjects design and fixations were recorded in all conditions. The results showed that the information demand varied according to the information in the display and the traffic light phase. A comparison of button presses with fixations showed that one unmasking interval came along with one fixation on the display. As a conclusion, the MARS method can distinguish between conditions with high and low information demand for the display. Button presses relate to fixations on the display. Hence, the MARS method is a promising tool to assess the information demand in dynamic environments and can be applied as an extension or alternative for eye tracking.     

‘I download my prayer schedule’: exploring the technological mediation of Islamic religious practice at work

The practice of daily prayers in Islam and how observances such as Ramadan fall each year follow specific solar or lunar calendars different from the Gregorian calendar of UK work places. Identifying the time for daily prayers and finding a place to practise is a skilled activity requiring ways to ascertain the correct (and changing) time and a place in which prayer can take place. In the absence of traditional mediation such as the call to prayer broadcast from a local mosque, new, often technologically innovative, approaches are being adopted. This paper reports on a study of how Muslims practise and negotiate the difficulties of performing daily prayers in a UK university. Though technological mediation is a significant aspect of daily prayers, it is but one part of a complex practice which often involves multiple technologies and multiple ways of working.     

哈贝马斯科技伦理观述评——哈贝马斯《作为"意识形态"的技术与科学》解读

哈贝马斯关于科学技术执行着意识形态的职能的思想,进一步发展了霍克海默和马尔库塞的科学伦理思想。同时这又是他试图进行历史唯物主义“重建”的序曲。哈贝马斯通过对韦伯的合理化的伦理观进行解析和批判,提出了交往关系的伦理解释框架,辨析了科学技术意识形态化的社会制度背景,并认为,只有随着资本主义生产方式的出现,制度框架的合理性才能直接同社会劳动系统联系在一起。科学技术成为第一位的生产力使国家干预活动的增加,同时技术与科学具有意识形态的作用。哈贝马斯揭示了晚期资本主义社会科学技术发展的新动向,也可以引发我们对科学技术的合理应用的思考。然而,在哈贝马斯关于科学技术意识形态化的批判中,的确存在着方法论的误区。     

Comparative analysis of the risk-handling procedures for gene technology applications in medical and plant science

In this paper we analyse how the risks associated with research on transgenic plants are regulated in Sweden. The paper outlines the way in which pilot projects in the plant sciences are overseen in Sweden, and discusses the international and national background to the current regulatory system. The historical, and hitherto unexplored, reasons for the evolution of current administrative and legislative procedures in plant science are of particular interest. Specifically, we discuss similarities and differences in the regulation of medicine and plant science, and we examine the tendency towards dichotomizing risk — focusing on social/ethical risks in medicine and biological risks in plant science. The context of this article is the Synpraxia research project, an inter-disciplinary program combining expertise in sciences and the humanities.     

Diversity and unity of modularity

Since the publication of Fodor's (1983) The Modularity of Mind, there have been quite a few discussions of cognitive modularity among cognitive scientists. Generally, in those discussions, modularity means a property of specialized cognitive processes or a domain-specific body of information. In actuality, scholars understand modularity in many different ways. Different characterizations of modularity and modules were proposed and discussed, but they created misunderstanding and confusion. In this article, I classified and analyzed different approaches to modularity and argued for the unity of modularity. Modularity is a multidimensional property consisting of features from several dimensions specifying different aspects of cognition. Among those, there are core features of modularity, and these core features form a cross-dimensional unity. Despite the diverse and liberal characterizations, modularity contributes to cognitive science because of the unity of the core features.     

Statistical manifold as an affine space: A functional equation approach

A statistical manifold M_μ consists of positive functions f such that defines a probability measure. In order to define an atlas on the manifold, it is viewed as an affine space associated with a subspace of the Orlicz space L^Φ. This leads to a functional equation whose solution, after imposing the linearity constrain in line with the vector space assumption, gives rise to a general form of mappings between the affine probability manifold and the vector (Orlicz) space. These results generalize the exponential statistical manifold and clarify some foundational issues in non-parametric information geometry.     

Lost in Translation? The Need for ‘Upstream Engagement’ with Nanotechnology on Trial

Nowadays, the criticism of the so-called ‘deficit model’ and the need for ‘upstream engagement’ in science and technology are becoming part of the master narratives of public policies in many countries, especially concerning nanotechnology. This may be considered as a major success for STS scholars, whose research results have largely contributed to this change, especially those concerning the GMO controversies. Some STS scholars thus move from a position of distant and critical observers to the role of experts in social engineering or advisers of policy-makers. However, in their enthusiasm concerning the expected benefits of upstream engagement, institutions, TA practitioners and social scientists seem to ignore some important limitations as well as the implicit framing assumptions of the concept. Based on an experience made by a group of social scientists in the Grenoble area—one of the major ‘nanodistricts’ in Europe—our paper shows that the ‘upstream engagement’ concept is still embedded in a linear model of innovation and is not very useful to anyone pursuing the co-production of innovations. It is especially true when socio-technical networks are already aligned by powerful actors and a worldwide agenda as in the case of nanotechnology. In order to give an opportunity for public engagement to have a larger impact on decision-making, we propose an alternative approach, which combines Actor–Network Theory (ANT), as an analytical tool, with the reflexive and ongoing implementation of public participation. Public engagement is probably one of the critical loci where STS scholars must reflect on the articulation between the knowledge they produce and public policies in action.     

Count out your intrusions: Effects of verbal encoding on intrusive memories

Peri-traumatic information processing is thought to affect the development of intrusive trauma memories. This study aimed to replicate and improve the study by Holmes, Brewin, and Hennessy (2004, Exp. 3) on the role of peri-traumatic verbal processing in analogue traumatic intrusion development. Participants viewed an aversive film under one of three conditions: counting backwards in 3s (“verbal interference”), verbalising emotions and thoughts (“verbal enhancement”), or without an extra task. A dual-process account of PTSD would predict that verbal interference would increase intrusion frequency compared to no task, whereas verbal enhancement would lead to a decrease. In contrast, mainstream memory theory predicts a decrease in intrusion frequency from any concurrent task that diverts attention away from the trauma film. The main finding was that the verbal interference task led to a decrease in intrusive memories of the film compared to the other two conditions. This finding does not support a dual-process account of PTSD, but is in line with general theories of memory and attention.
