This article provides an ethical evaluation of the CIA's use of Unmanned Aerial Vehicles (UAV's) to target so‐called terror suspects and insurgents. It utilises Christian informed deontological and virtue‐ethical criteria to assess this practise. These criteria include just intent, charity, proportionality, moral consistency, truthfulness, mercy, courage and prudence. The article concludes that the UAV target programme is morally problematic. The United States’ ‘kill not capture’ policy as exemplified in the use of ‘signature’ strikes defies the virtues at stake. By using UAV's as tools for preventive warfare, utilising armed UAV's that are weapons of war outside areas of armed conflict and disregarding the principles of transparency, last resort and proportionality, the United States is employing UAV's in a morally illegitimate and imprudent way, and is setting precedents that might have dire consequences for global peace and the security of future generations.  相似文献

This research examined how performance feedback moderates the effects of individuals' achievement goals on information exchange when carrying out a novel and complex task. Experiment 1 demonstrated that mastery goal individuals who received positive performance feedback gave less modified information about their task performance to their exchange partner relative to both mastery goal individuals who received negative feedback and performance goal individuals (who received either negative or positive feedback). In Experiment 2, we found that relative to performance goals, mastery goals led to a stronger reciprocity orientation and a weaker exploitation orientation. Also, mastery goal individuals provided information of higher quality than performance goal individuals, thereby explaining the observed findings in Experiment 1.  相似文献

Abstract

The concept of “appraisal” has been used in the literature in a dual way: to refer to the content of emotional experience, as well as to the cognitive antecedents of emotions. I argue that appraisal in the former sense is what is contained in information in self-reports and that this information is of limited use for making inferences on emotion antecedents. This is so because emotional experience may contain appraisals that are part of the emotional response rather than belonging to its causes. They often result from elaboration of the experience after it has begun to be generated. Although in most or all emotions some cognitive appraisal processes are essential antecedents, these processes may be much simpler than self-reports (and the semantics of emotion words) may suggest. The appraisal processes that account for emotion elicitation can be assumed to be of a quite elementary kind.  相似文献

Abstract

This article examines the libertarian arguments of Jan Narveson and James P. Sterba regarding the compatibility of liberty and equality. It then posits that their arguments fail in solving tensions between liberty and equality, because all fundamental rights cannot be derived from liberty. A coherent scheme of human rights is only possible if human dignity is used to balance the conflicting interests of liberty and equality. It then proceeds to make some suggestions on how human dignity as core value might help to solve tensions between equality and liberty.  相似文献

Given the widespread use and well-known consequences of achievement goals in different competence-relevant situations, it is important to gain a thorough understanding of how these differences in goal pursuit are formed. Using different analytic approaches, we show that birth order lies at the heart of people’s goal preferences as we consistently found that firstborns have developed a preference for mastery goals (which are based on self-referenced standards of competence), whereas secondborns have developed a preference for performance goals (which are based on other-referenced standards of competence). These findings may help explain why people differently define, experience, and respond to competence-relevant situations, including the workplace, the classroom, and the ball field.  相似文献

During times of crisis, do cognitive processes shape leaders’ procurement decisions in predictable ways? Drawing on psychological literature, we propose four factors that may have a substantial influence on how much money leaders engaged in ongoing disputes allocate to their military: (1) striving for superiority versus striving for parity in military resources; (2) uncertainty regarding the characteristics of weapons systems; (3) ambiguity regarding the overall capacities of weapons systems; and (4) the tone of messages that adversaries send to one another. The effects of these factors are investigated using a laboratory simulation that combines both experimental and quasi‐experimental elements. The results indicate that striving for superiority has a significant effect on defense spending, as does the tone of an opponent’s message. By way of contrast, neither uncertainty nor ambiguity exerts a statistically discernable impact on the level of defense spending.  相似文献

Whoever paid the bill at the restaurant last night, will clearly remember doing it. Independently from the type of action, it is a common experience that being the agent provides a special strength to our memories. Even if it is generally agreed that personal memories (episodic memory) rely on separate neural substrates with respect to general knowledge (semantic memory), little is known on the nature of the link between memory and the sense of agency. In the present paper, we review results from two experiments investigating the effects of agency on both explicit and implicit memory traces. Performance of normal subjects is compared to that of schizophrenic patients in order to explore the role of awareness of action on memory. It is proposed that reliable first-person information is necessary to create a stable and coherent motor memory trace.  相似文献

Although it is clear that emotional and motivational manipulations yield a strong influence on cognition and behaviour, these domains have mostly been investigated in independent research lines. Therefore, it remains poorly understood how far these affective manipulations overlap in terms of their underlying neural activations, especially in light of previous findings that suggest a shared valence mechanism across multiple affective processing domains (e.g., monetary incentives, primary rewards, emotional events). This is particularly interesting considering the commonality between emotional and motivational constructs in terms of their basic affective nature (positive vs. negative), but dissociations in terms of instrumentality, in that only reward-related stimuli are typically associated with performance-contingent outcomes. Here, we aimed to examine potential common neural processes triggered by emotional and motivational stimuli in matched tasks within participants using functional magnetic resonance imaging (fMRI). Across tasks, we found shared valence effects in the ventromedial prefrontal cortex and left inferior frontal gyrus (part of dorsolateral prefrontal cortex), with increased activity for positive and negative stimuli, respectively. Despite this commonality, emotion and reward tasks featured differential behavioural patterns in that negative valence effects (performance costs) were exclusive to emotional stimuli, while positive valence effects (performance benefits) were only observed for reward-related stimuli. Overall, our data suggest a common affective coding mechanism across different task domains and support the idea that monetary incentives entail signed basic valence signals, above and beyond the instruction to perform both gain and loss trials as accurately as possible to maximise the outcome.  相似文献
