In the last decade we have entered the era of remote controlled military technology. The excitement about this new technology should not mask the ethical questions that it raises. A fundamental ethical question is who may be held responsible for civilian deaths. In this paper we will discuss the role of the human operator or so-called ‘cubicle warrior’, who remotely controls the military robots behind visual interfaces. We will argue that the socio-technical system conditions the cubicle warrior to dehumanize the enemy. As a result the cubicle warrior is morally disengaged from his destructive and lethal actions. This challenges what he should know to make responsible decisions (the so-called knowledge condition). Nowadays and in the near future, three factors will influence and may increase the moral disengagement even further due to the decrease of locus of control orientation: (1) photo shopping the war; (2) the moralization of technology; (3) the speed of decision-making. As a result, cubicle warriors cannot be held reasonably responsible anymore for the decisions they make.  相似文献

The amount of health information available on the Internet is considerable. In this context, several health gateways have been developed. Among them, CISMeF (Catalogue and Index of Health Resources in French) was designed to catalogue and index health resources in French. The goal of this article is to describe the various enhancements to the MeSH thesaurus developed by the CISMeF team to adapt this terminology to the broader field of health Internet resources instead of scientific articles for the medline bibliographic database. CISMeF uses two standard tools for organizing information: the MeSH thesaurus and several metadata element sets, in particular the Dublin Core metadata format. The heterogeneity of Internet health resources led the CISMeF team to enhance the MeSH thesaurus with the introduction of two new concepts, respectively, resource types and metaterms. CISMeF resource types are a generalization of the publication types of medline. A resource type describes the nature of the resource and MeSH keyword/qualifier pairs describe the subject of the resource. A metaterm is generally a medical specialty or a biological science, which has semantic links with one or more MeSH keywords, qualifiers and resource types. The CISMeF terminology is exploited for several tasks: resource indexing performed manually, resource categorization performed automatically, visualization and navigation through the concept hierarchies and information retrieval using the Doc'CISMeF search engine. The CISMeF health gateway uses several MeSH thesaurus enhancements to optimize information retrieval, hierarchy navigation and automatic indexing.  相似文献

The aim of this study was to determine whether there is an effect of time of day on the adaptation to strength training at maximal effort. Fourteen participants took part in this experiment. Their peak anaerobic power (Wingate anaerobic test) and peak knee extension torque at six angular velocities (1.05, 2.10, 3.14, 4.19, 5.24 and 6.29 rad x s(-1)) were recorded in the morning (between 07:00 and 08:00 h) and in the evening (between 17:00 and 18:00 h) just before and 2 weeks after a 6 week course of regular training. Seven of them trained only in the morning and seven only in the evening. Multivariate analysis of variance revealed a significant group x pre-/post-training x time of day interaction effect for peak torque and peak anaerobic power. Before training, in both groups, peak torque and peak anaerobic power were significantly higher in the evening than in the morning. After training, there was no significant difference in peak torque and peak anaerobic power between the morning and the evening for the morning training group. In contrast, in the evening training group, peak torque and peak anaerobic power were higher in the evening than in the morning. As a result of training, both peak torque and peak anaerobic power increased from their initial values as expected. The morning training group improved their peak anaerobic power significantly in the morning and in the evening, the absolute increase being larger in the morning than in the evening. The evening training group did not improve their peak anaerobic power in the morning, whereas it improved significantly in the evening. Although peak torque was significantly improved by training in the morning and evening in both groups, the absolute increase was greater in the morning than in the evening in the morning training group, whereas the opposite was the case for the evening training group. These results suggest that training twice a week at a specific hour increases the peak torque and the peak anaerobic power specifically at this hour and demonstrates that there is a temporal specificity to strength training.  相似文献

According to the literature, in recent years, developing experiential learning has fulfilled the requirement of a deep understanding of lean philosophy by engineering students, demonstrating the advantages and disadvantages of some of the key principles of lean manufacturing. On the other hand, the literature evidences how some kinds of game-based experiential learning overlook daily difficulties, which play a central role in manufacturing systems. To fill the need of a game overcoming such lack of vision, an innovative game direct in-field, named Kart Factory, has been developed. Actual production shifts are simulated, while keeping all the elements peculiar to a real production set (i.e. complexity, effort, safety). The working environment is a real pedal car assembly department, the products to be assembled have relevant size and weight (i.e. up to 35 kg approximately), and the provided tools are real production equipment (e.g. keys, screwdrivers, trans-pallets, etc.). Due to the need to maximise the impact on students, a labour-intensive process characterises the production department. The whole training process is based on three educational principles: Experience Value Principle, Error Value Principle, and Team Value Principle. As the ‘learn by doing’ and ‘learn by failing’ are favoured, the theory follows the practice, while crating the willingness to ‘do’ instead of just designing or planning. The gathered data prove the Kart Factory's effectiveness in reaching a good knowledge of lean concepts, notwithstanding the students’ initial knowledge level.  相似文献

Purpose: The aim of the paper is to analyse the use of Communities of Practice and Information and Communication Technology (ICT) to enhance knowledge sharing between researchers and advisors. The associated research question is to what extent ICT supported a virtual Community of Practice and has been effective in counteracting fragmentation between research and advisory systems in terms of knowledge sharing between these two pillars of the Italian Agricultural Knowledge System (AKS).

Design/Methodology/approach: The paper uses a mixed methods approach: a questionnaire submitted to the Community of Practice participants on their experiences, observation of interaction between Community of Practice participants and data on the use of the ICT platform.

Findings: The ICT supported Community of Practice approach appears to improve knowledge sharing between researchers and advisors, and also draws in other actors of the broader Agricultural Knowledge and Innovation System in which the AKS is embedded. However, ICT based tools alone are not sufficient and need to be complemented with face-to-face (non-virtual) interactions. A clear theoretical implication of this study is that this is an iterative process in which virtual and non-virtual interaction mutually reinforce each other: ICT interaction spurs real life and face-to-face interaction, and ICT supports follow-up on real life face-to-face interaction.

Practical Implications: Communities of Practice can be a useful tool for knowledge sharing between research and advisory systems, but should have a degree of flexibility in terms of the topics they address and should accommodate new members when appropriate. ICT is supportive, but should be complemented by real life meetings.

Originality/Value: The paper connects recent frameworks of the use of Communities of Practice with literature on ICT in agriculture and adds insights on the contribution of combining virtual and non-virtual interaction in Communities of Practice aimed at knowledge sharing.  相似文献

Adolescence is marked by the development of personal identity and is associated with structural and functional changes in brain regions associated with Self processing. Yet, little is known about the neural correlates of self‐reference processing and self‐reference effect in adolescents. This functional magnetic resonance imaging study consists of a self‐reference paradigm followed by a recognition test proposed to 30 healthy adolescents aged 13–18 years old. Results showed that the rostral anterior cingulate cortex is specifically involved in self‐reference processing and that this specialization develops gradually from 13 to 18 years old. The self‐reference effect is associated with increased brain activation changes during encoding, suggesting that the beneficial effect of Self on memory may occur at encoding of self‐referential information, rather than at retrieval.  相似文献

The aim of this study was to define the time-motion (i.e., fighting, preparatory and breaking activity), technical (i.e., attack, timed-attack, counterattack, blocking and grasps) and tactical (i.e., upper limb, lower-limb, combination and throwing) profiles of the senior top-level karate competition played under the most recent rules of the International Karate Federation in relation to gender, match outcome and weight categories. Time-motion, tactical actions and technical executions were investigated of senior karatekas (n = 60) during the Karate World Championship. The referee’s decisions caused an overall activity-to-break ratio of ~1:1.5 with a significant difference (= 0.025) between karateka’s weight categories (light = 1:1.5; middle = 1:2 and heavy = 1:1). High-intensity actions (i.e., attack and defensive actions performed quickly and powerfully) were higher in male compared to female athletes. Top-level karatekas used upper limb techniques more than lower limb ones, with both applied in the head more than in the body. For the high-intensity-actions to pause ratio and the percentage of combined techniques, light weight category was significantly higher than middle weight category. These findings suggest that training programs may need to be specific to the requirements of the gender and weight categories.  相似文献

Research on elites (that is, on status groups that occupy dominant positions) is characterized by the lack of connection between studies that focus on elite recruitment and those that focus on the exercise of power by elites. As underlined by Giddens (Elites and power in British society, 1974), both types of approach are important and should complement each other in the analysis of mediations between the class structure, the organizational structure and the power structure in a given society. Giddens also insists on the need for recruitment studies to take account of two different dimensions: the types of channel that are privileged by elite groups to reproduce their social position, and the degree of social closure or openness of these channels to other groups (Parkin, The social analysis of class structure, 1974). This distinction is used to organize the present chapter, which focuses on a single channel that has come to play a crucial role in post-industrial societies, that is schools and, more precisely, upper secondary and higher education institutions, and on their influence in three different national contexts: France, the United Kingdom and the United States. In the first section, the specific features of elite education are examined. The second section explores the extent and modes of institutional and social closure.  相似文献

Outbreaks of foodborne illness generally receive abundant print media coverage. However, the framing of outbreaks and representations of foodborne pathogens in the media discourse are not necessarily homogeneous. Drawing on previous research on media coverage of emerging diseases and on the conceptual tools of framing theory, this paper explores the diversity of frames and representations used in the media coverage of two listeriosis outbreaks that occurred in Canada in fall 2008. In the dominant war against microbes frame, microbes are portrayed as posing serious risks that call for stringent control measures. This frame coexists with other frames which rather emphasize economic, ecosystem or nutrition issues and which are supported by representations of microbial risks that either mitigate these risks, present them as inevitable or as less serious than others. The implications of these observations for the public understanding of foodborne microbial risks are discussed.  相似文献
