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

Delay discounting is the process by which the value of an expected reward decreases as the delay to obtaining that reward increases. Individuals with higher discounting rates tend to prefer smaller immediate rewards over larger delayed rewards. Previous research has indicated that personality can influence an individual's discounting rates, with higher levels of Extraversion predicting a preference for immediate gratification. The current study examined how this relationship would be influenced by situational mood inductions. While main effects were observed for both Extraversion and cognitive ability in the prediction of discounting rates, a significant interaction was also observed between Extraversion and positive affect. Extraverted individuals were more likely to prefer an immediate reward when first put in a positive mood. Extraverts thus appear particularly sensitive to impulsive, incentive-reward-driven behavior by temperament and by situational factors heightening positive affect. 相似文献

Under some circumstances, moving objects capture attention. Whether a change in the direction of a moving object attracts attention is still unexplored. We investigated this using a continuous tracking task. In Experiment 1, four grating patches changed smoothly and semirandomly in their positions and orientations, and observers attempted to track the orientations of two of them. After the stimuli disappeared, one of the two target gratings was queried and observers reported its orientation; hence direction of the gratings' motion across the screen was an irrelevant feature. Despite the irrelevance of its motion, when the nonqueried grating had collided with an invisible boundary within the last 200 msec of the trial, accuracy reporting the queried grating was worse than when it had not. Attention was likely drawn by the unexpected nature of these changes in direction of motion, since the effect was eliminated when the boundaries were visible (Experiment 2). This tendency for unexpected motion changes to attract attention has important consequences for the monitoring of objects in everyday environments. 相似文献

The current study developed a multi-dimensional measure of beliefs around luck. Two studies introduced the Darke and Freedman beliefs around luck scale where the scale showed a consistent 4 component model (beliefs in luck, rejection of luck, being lucky, and being unlucky) across two samples (n = 250; n = 145). The scales also show adequate reliability statistics and validity by ways of comparison with other measures of beliefs around luck, peer and family ratings and expected associations with measures of personality, individual difference and well-being variables. 相似文献

‘Evidentialism’ is the conventional name (given mainly by its opponents) for the view that there is a moral duty to proportion
one’s beliefs to evidence, proof or other epistemic justifications for belief. This essay defends evidentialism against objections
based on the alleged involuntariness of belief, on the claim that evidentialism assumes a doubtful epistemology, that epistemically
unsupported beliefs can be beneficial, that there are significant classes of exceptions to the evidentialist principle, and
other shabby evasions and alibis (as I take them to be) for disregarding the duty to believe according to the evidence. Evidentialism
is also supported by arguments based on both self-regarding and other-regarding considerations. 相似文献

Characteristics of problem gamblers 56 years of age or older: a statewide study of casino self-excluders 总被引:1,自引:0,他引:1
Gambling among older adults appears to be increasing, though little is known about the characteristics of older adult problem gamblers. The purpose of this study was to compare older adults to younger and middle-aged adults in a cohort of problem gamblers participating in a state-administered casino self-exclusion program. Self-reported problem gamblers (N = 1,601) who voluntary banned themselves from Missouri casinos from 2001 to 2003 were categorized by age as younger adults (ages 21 to 35; n = 490), middle-aged adults (ages 36 to 55; n = 950), and older adults (ages 56 to 79; n = 161), and were compared with respect to demographic variables, gambling participation, and reasons for self-exclusion. Older adult self-excluders typically began gambling in midlife, experienced gambling problems around age 60, reported preferences for nonstrategic forms of gambling, and identified fear of suicide as the primary reason for self-excluding. Implications for intervention, prevention and treatment are discussed. (PsycINFO Database Record (c) 2008 APA, all rights reserved). 相似文献

Among individuals with Rheumatoid Arthritis (RA), pain-associated stress can severely impact wellbeing. Psychological attributes, such as a sense of personal mastery, may attenuate the effects of chronic pain on life quality. We tested the hypothesis that a high sense of mastery would predict lower pain, perceived stress, fatigue, and mean arterial pressure (MAP) than would a low sense of mastery during an acute, interpersonal stressor.Seventy-four individuals with RA completed a psychophysiological laboratory session involving MAP measurements, as well as self-ratings of stress, joint pain, and fatigue. Measurements were collected before, during, and after an interpersonal stressor. To assess personal mastery, exploratory and confirmatory factor analyses were conducted on the Pearlin Mastery Scale based on recommendations by Reich and Zautra (1991)The Pearlin Mastery Scale yielded two distinct factors: fatalism and control. Both fatalism and control were significant predictors of the wellbeing variables. Individuals with a highly fatalistic style demonstrated higher general levels of mean arterial pressure (F(1) = 3.41, p<.1) and reported greater joint pain (F(1) = 4.72, p<.05) across all periods. Individuals with a high sense of control also evidenced lower MAP (F(1) = 3.73, p<.1) and reported less stress (F(1) = 7.44, p<.01) and fatigue (F(1) = 5.16, p<.05). Neither fatalism nor control were related to objective measures of disease severity (r's = -.10, p=NS and -.02, p=NS, respectively).RA patients with a high level of personal mastery, as evidenced by scores on two distinct indices, experience lower MAP, and report less pain, stress and fatigue. Although fatalism and control were not related to objective disease state, they seem to play an important role in the experience of wellbeing for people with RA. 相似文献

We examined parents’ knowledge, attitudes, and information sources regarding Attention-Deficit/Hyperactivity Disorder (ADHD),
including treatment with stimulant medication and behavioral interventions. Responses from parents with a child diagnosed
with ADHD and parents without a child diagnosed with ADHD were also compared. Participants consisted of 146 parents of elementary
age children from Wisconsin. The surveyed parents were aware of issues surrounding ADHD and the use of stimulant medication,
but there were several areas where they possessed inaccurate or incomplete factual information. Parents who had a child diagnosed
with ADHD rated the effects of stimulant medication more positively and side effects as less severe than other parents. They
also rated behavioral interventions as less effective on all questions. Implications of the study are discussed. 相似文献

Research of the Gujarati Hindu communities of the United Kingdom and New Zealand has uncovered an extraordinary diversity of belief concerning the miraculous consumption of devotional food offerings by murtis. Devotees of certain traditions have experienced these events first-hand, but many Hindus believe the process is more subtle. Others suggest that such claims are attempts to gain spiritual authority among Hindus in the diaspora, some dismiss them as simply fraudulent. This article examines the appetite of the divine and how it is understood and contested by various Gujarati Hindu traditions in the United Kingdom and in New Zealand. It will assess the significance of food miracles and how they strengthen ideas of religious identity and spiritual validity as well as their role creating a palpable tension between traditions as to who authoritatively represents Hinduism in the diaspora. 相似文献
