Inspired by the thinking of authors such as Andrew Feenberg, Tim Ingold and Richard Sennett, this article sets forth substantial criticism of the ‘social uprooting of technology’ paradigm, which deterministically considers modern technology an autonomous entity, independent and indifferent to the social world (practices, skills, experiences, cultures, etc.). In particular, the authors’ focus on demonstrating that the philosophy,methodology and experience linked to open source technological development represent an emblematic case of re-encapsulation of the technical code within social relations (reskilling practices). Open source is discussed as a practice, albeit not unique, of community empowerment aimed at the participated and shared rehabilitation of technological production ex-ante. Furthermore, the article discusses the application of open source processes in the agro-biotechnological field, showing how they may support a more democratic endogenous development, capable of binding technological innovation to the objectives of social (reducing inequalities) and environmental sustainability to a greater degree. 相似文献

Elucidating the neural basis of joint attention in infancy promises to yield important insights into the development of language and social cognition, and directly informs developmental models of autism. We describe a new method for evaluating responding to joint attention performance in infancy that highlights the 9‐ to 10‐month period as a time interval of maximal individual differences. We then demonstrate that fractional anisotropy in the right uncinate fasciculus, a white matter fiber bundle connecting the amygdala to the ventral‐medial prefrontal cortex and anterior temporal pole, measured in 6‐month‐olds predicts individual differences in responding to joint attention at 9 months of age. The white matter microstructure of the right uncinate was not related to receptive language ability at 9 months. These findings suggest that the development of core nonverbal social communication skills in infancy is largely supported by preceding developments within right lateralized frontotemporal brain systems. 相似文献

Recent developments in biogerontology—the study of the biology of ageing—suggest that it may eventually be possible to intervene in the human ageing process. This, in turn, offers the prospect of significantly postponing the onset of age-related diseases. The biogerontological project, however, has met with strong resistance, especially by deontologists. They consider the act of intervening in the ageing process impermissible on the grounds that it would (most probably) bring about an extended maximum lifespan—a state of affairs that they deem intrinsically bad. In a bid to convince their deontological opponents of the permissibility of this act, proponents of biogerontology invoke an argument which is grounded in the doctrine of double effect. Surprisingly, their argument, which we refer to as the ‘double effect argument’, has gone unnoticed. This article exposes and critically evaluates this ‘double effect argument’. To this end, we first review a series of excerpts from the ethical debate on biogerontology in order to substantiate the presence of double effect reasoning. Next, we attempt to determine the role that the ‘double effect argument’ is meant to fulfil within this debate. Finally, we assess whether the act of intervening in ageing actually can be justified using double effect reasoning. 相似文献

Recent high quality papers have renewed interest in the phenomenon of neurogenesis within the adult mammalian brain. Many studies now show that neurogenesis can be modulated by environmental factors including physical activity, stress, and learning. These findings have considerable implications for neuroscience in general, including the study of learning and memory, neural network plasticity, aging, neurodegeneration, and the recovery from brain injury. Although new light has been shed on this field, many contradictory findings have been reported. Here we propose two principle issues which underlie these inconsistencies, with particular focus on the interaction between learning and neurogenesis. The first issue relates to the basic methodology of measuring the generation of new brain cells, i.e., proliferation, as compared to survival of the newly made cells. Mostly, measures of neurogenesis reported are a combination of proliferation and survival, making it impossible to distinguish between these separate processes. The second aspect is in regards to the role of environmental factors which can affect both proliferation and survival independently. Especially the interaction between stress and learning is of importance since these might counteract each other in some circumstances. Reviewing the literature while taking these issues into account indicates that, in contrast to some findings, cell proliferation in the dentate gyrus of the hippocampus as a result of learning cannot be ruled out yet. On the other hand, increased survival of granule cells in the dentate gyrus as a result of hippocampal-dependent learning has been clearly demonstrated. Moreover, this learning-induced survival of granule cells, which were born before the actual learning experience, might provide a molecular mechanism for the 'use it or lose it' principle. 相似文献

Competency models are available for many aspects of work that cut across various occupations (such as leadership, teamwork, etc.). Although virtual teamwork has developed to a highly prevalent aspect of work, very little is known about the knowledge, skills, abilities, and other characteristics (KSAOs) required. In the current study, KSAO requirements of virtual and traditional business teams (n = 175 and 205, respectively) were compared and aligned to the Great Eight competency model. Results showed that KSAOs pertaining to Leading and Deciding and to Analyzing and Interpreting were more important in virtual teams. Conversely, virtual and traditional teams did not differ in terms of broad personality (Big Five) requirements. Together, these findings contribute to deeper knowledge on selection and training in virtual teams. 相似文献

In two experiments we demonstrated that a self-evaluation threat intensifies schadenfreude. Moreover, we showed that a self-evaluation threat predicts schadenfreude in both threat-related and threat-unrelated domains and when controlling for feelings of envy and dislike towards the target and evaluations of the misfortune in terms of deservingness. These findings indicate that another's misfortune may be pleasing because it satisfies people's concern for a positive self-view and a sense of self-worth. 相似文献

Individuals?? level of depression has been shown to systematically determine their amount of effort-related cardiovascular reactivity (see Brinkmann and Gendolla in Motiv Emot, 31:71?C82, 2007; J Pers Soc Psychol, 94:146?C157, 2008). By means of a mood cue manipulation the present study aimed at providing a conclusive test whether this is due to the informational impact of depressed mood. After habituation, students with low versus high depression scores worked on a memory task under ??do-your-best?? instructions. Half of them received a cue before the task, suggesting that their current mood may have an impact during task performance. As expected, dysphoric participants showed higher systolic blood pressure reactivity during task performance than nondysphorics when no cue was given. This pattern was reversed in the cue condition, indicating that dysphorics effectively managed to reduce the depressive mood impact on their task demand appraisals and effort mobilization. 相似文献

Although analogical reasoning has long been a popular method of reasoning in bioethics, current literature does not sufficiently
grasp its variety. We assert that the main shortcoming is the fact that an analogy’s value is often judged on the extent of
similarity between the source situation and the target situation, while in (bio)ethics, analogies are often used because of certain dissimilarities rather than in spite of them. We make a clear distinction between dissimilarities that aim to reinforce a similar approach in the source situation
and the target situation and dissimilarities that aim to undermine or denounce a similar approach. The former kind of dissimilarity
offers the analogy more normative force than if there were no dissimilarities present; this is often overlooked by authors
who regard all relevant dissimilarities as detrimental to the analogy’s strength. Another observation is that an evaluation
of the normative force of an analogy cannot be made independently of moral principles or theories. Without these, one cannot
select which elements in an analogy are morally relevant nor determine how they should be interpreted. 相似文献

In our response, we aim to further contribute to the ongoing discussion of the construct of positivity and of the related research. We believe that each of the three commentaries has something unique to offer to the literature. By this response we take the opportunity to discuss the ideas that they present, and to illustrate some additional thoughts about positivity and its relationships with germane psychological constructs. 相似文献
