If states have the moral authority to decide their memberships by denying citizenship, I argue that they may also strip citizenship, from law-abiding members, for the same reasons. The only real difference is that when states revoke citizenship they may need to compensate people for their prior contributions, but that is not unlike what frequently occurs in divorce. Once just termination rules are established, stripping citizenship could become, like divorce, an everyday event. Partly because of this implication, we should reject the membership authority of states.  相似文献

Depression, anxiety, and stress are among major psychological disorders being predominant in present day. This study proposed to analyze the role of Muslim religiosity in male students showing these mental indications. A sample including 723 Pakistani young adults enrolled at college level was randomly chosen. Muslim Religiosity Measurement Scale and Depression, Anxiety and Stress Scale were utilized to gather information. Discoveries uncover an inverse relationship between conduct and affiliation with the symptoms of mental disorders, anxiety and stress among the respondents. Results bolster the incorporation of religious dimensions in psychological wellness and mental well-being thought of young adults in Pakistan.  相似文献

Abstract

Violent attacks against innocent civilians occurring on an everyday and global basis have intensified the discourse on terrorism. However, like pornography, terrorism seems readily recognizable but hard to define. The designation is applied to the destructive acts of religious zealots, mentally unstable individuals, terror-inducing despots, separatist militia, and, at times, even legitimate freedom fighters. Ordinary language fails to define terrorism’s nosological circumference and is itself defiled in the process. While acknowledging this denotational conundrum, this paper will propose that the origins of the current mayhem by the radicalized few reside in three geopolitical realms. These include the long shadow of colonialism, the hypocrisy and violence of certain Western foreign policies, and some fundamental problems in the societies that form the crucible of such rage. As a result, ameliorative strategies need to be directed at (and require the collaboration of) all three parties at the root of this tragic and bloody scenario.  相似文献

Israel has a long history of concern with chemical and biological threats, since several hostile states in the Middle East are likely to possess such weapons. The Twin-Tower terrorist attacks and Anthrax envelope scares of 2001 were a watershed for public perceptions of the threat of unconventional terror in general and of biological terror in particular. New advances in biotechnology will only increase the ability of terrorists to exploit the burgeoning availability of related information to develop ever-more destructive bioweapons. Many areas of modern biological research are unavoidably dual-use by nature. They thus have a great potential for both help and harm; and facilitating the former while preventing the latter remains a serious challenge to researchers and governments alike. This article addresses how Israel might best (1) prevent hostile elements from obtaining, from Israel’s biological research system, materials, information and technologies that might facilitate their carrying out a biological attack, while (2) continuing to promote academic openness, excellence and other hallmarks of that system. This important and sensitive issue was assessed by a special national committee, and their recommendations are presented and discussed. One particularly innovative element is the restructuring and use of Israel’s extensive biosafety system to also address biosecurity goals, with minimal disruption or delay.  相似文献

The use of visual occlusion as a cue to altitude maintenance in low-altitude flight (LAF) was investigated. The extent to which the ground surface is occluded by 3-D objects varies with altitude and depends on the height, radius, and density of the objects. Participants attempted to maintain a constant altitude during simulated flight over an undulating terrain with trees of various heights, radii, and densities. As would be predicted if participants used occlusion, root-mean-square error was related to the product of tree height and tree density (Experiment 1) and to the product of tree radius and tree density (Experiment 2). This relationship was also found for simulated terrains with a more realistic mixture of tree heights (Experiment 4). The authors present a modification to an occlusion model (T. Leung & J. Malik, 1997) that can be used to approximate occlusion in the context of LAF, and they evaluate the modified model using the present LAF data. On a practical level, simulating 3-D objects is computationally expensive. The present results suggest that performance may be maintained with fewer objects if their size is increased.  相似文献

The aim of the study was to explore whether temporal information processing can interfere with performance of a non-temporal task. A new methodology based on the Garner paradigm was employed. Participants were asked to classify two-dimensional stimuli according to either length or duration, with and without variation in the other (task-irrelevant) dimension. Garner interference was detected only with respect to classification by length when irrelevant variation in duration was present. Stroop interference was detected only in classification by length across compatible and non-compatible values of length and duration. Classification by length took more time when done with variation in duration than when duration was constant. Classification by length also took more time when length and duration were not compatible than when they were compatible. The findings indicate that the processing of duration is similar to the processing of other perceptual dimensions. The processing of duration consumes attentional resources and can interfere with the processing of other perceptual dimensions. The findings support attentional models of prospective duration judgment.  相似文献
