With the challenge of communicating climate science in the United States and making progress in international negotiations on climate change there is a need for other approaches. The moral issues of ecological degradation and climate justice need to be integrated into social consciousness, political legislation, and climate treaties. Both science and religion can contribute to this integration with differentiated language but shared purpose. Recognizing the limits of both science and religion is critical to finding a way forward for addressing the critical challenges of climate change. How we value nature and human–Earth relations is crucial to this. We need a broader environmental ethics in dialogue with the science of climate change. 相似文献

The primary goal of the present research was to examine cross-cultural validity of the Multidimensional State Boredom Scale (MSBS) by comparing a European Canadian sample and a Chinese sample. The secondary goal was to explore cross-cultural differences in the actual experience of boredom between European Canadian and Chinese participants when they completed a psychological survey. After establishing cross-cultural validity of the MSBS by eliminating items that functioned differentially across the two cultural groups, we found that European Canadians scored higher on the MSBS than did Chinese. Results are consistent with the literature on cultural differences in ideal affect, such that European North Americans (vs. East Asians) tend to value high-arousal positive affects (e.g., excitement) more, and low-arousal positive affect less (Tsai, Knutson, & Fung, 2006). 相似文献

It has been hypothesised that deficits in the functioning of the mirror neuron system (MNS) and internal modelling may contribute to the motor impairments associated with DCD. These processes can be explored behaviourally through motor imagery paradigms. Motor imagery proficiency of children with and without probable DCD (pDCD) was examined using a complex hand rotation task to explore whether motor imagery strategies could be used during more complex tasks. Forty-four boys aged 7–13 years participated, 22 with pDCD (mean = 9.90 years ± 1.57) and 22 controls (mean = 9.68 years ± 1.53). Participants completed the task twice: with and without motor imagery instructions. Stimuli were presented in two rotational axes – palm/back, and eight 45° rotational steps. Both groups showed evidence of following the biomechanical and postural constraints of actual movements. Responses of children with pDCD were slower and less accurate than controls, with group differences increasing alongside task complexity. A greater impact of biomechanical constraints for accuracy was observed in the DCD group. The response characteristics of children with pDCD likely reflects a reduced capacity to mentally manipulate a body schema and reduced visuo-motor processing capabilities. Behaviourally, these processes are linked to MNS and internal modelling function, suggesting deficits in these systems may contribute to the movement difficulties characteristic of DCD. 相似文献

Military personnel endure rigorous and demanding man-hours designated to monitoring and locating targets in tasks such as cyber defense and Unmanned Aerial Vehicle (UAV) operators. These tasks are monotonous and repetitive, which can result in vigilance decrement. The objective of the study was to implement a form of noninvasive brain stimulation known as transcranial DC stimulation (tDCS) over the left frontal eye field (LFEF) region of the scalp to improve cognitive performance. The participants received anodal and cathodal stimulation of 2 mA for 30 min as well as placebo stimulation on 3 separate days while performing the task. The findings suggest that anodal and cathodal stimulation significantly improves detection accuracy. Also, a correlation was detected between percent of eye closure (PERCLOS) and blinking frequency in relation to stimulation condition. Our data suggest that tDCS over the LFEF would be a beneficial countermeasure to mitigate the vigilance decrement and improve visual search performance. 相似文献

Ethical decision-making research has centered on Rest’s (1986) framework that represents a rational, nonaffective model for ethical decision making. However, research in human cognition suggesting a “dual-processing” framework, composed of both rational and affective components, has been relatively ignored in the ethical decision-making literature. Examining dual-processing literature, it seems affect might be an important factor in decision making when a person’s mood is congruent with the task or situational context frame. Given that ethical decisions are serious and complex tasks, it is proposed here that inducing a negative affective state might produce mood congruence, reinforce the salience of emotion for ethical decision makers, and lead to differences in decision processing. Evidence is presented documenting differences in the decisions made by ethical decision makers in a negative affective state as compared to those in either a positive or neutral affective state. 相似文献

Over the past 170 years, American psychiatry has progressively asserted its authority over a larger segment of the American population. From the mid-1800s to the end of World War II, psychiatry had authority over the asylum population, which markedly increased in the first half of the twentieth century due to the influence of eugenics, an ideology that argued the ‘mentally ill’ had to be segregated from society. After the war, American psychiatry adopted Freudian conceptions of mental disorders, which enabled it to begin treating people in the community who were ‘neurotic’ in some way, which dramatically expanded its influence in society. Then, in the 1970s, when many in American society were questioning psychiatry’s legitimacy as a branch of medicine, the American Psychiatric Association (APA) responded by adopting a disease model for diagnosing mental disorders, which it set forth in the third edition of its Diagnostic and Statistical Manual. There were no scientific discoveries that led to this new model, but soon the APA was informing the American public that mental disorders were diseases of the brain, and that psychiatric drugs helped fix those diseases, ‘like insulin for diabetes.’ The APA, in concert with pharmaceutical companies, has successfully exported this belief system to much of the developed world. In order to break free of this ‘therapeutic state,’ the public needs to understand the history of how it came to be, and see the social injury it has caused. 相似文献

This article explores the professional reflection of three male religious education (RE) student teachers during their one-year pedagogical training. The participants (n = 3) interviewed in this article were chosen on the basis of their self-report in the questionnaire in which they claimed no previous teaching experience. The participants were interviewed three times: at the beginning, in the middle and at the end of their one-year teacher education. The interviews were analysed with qualitative content analysis. The study showed some patterns in the student teachers reflections concerning developmental aims, professionalism, and convictions during the year. The article concludes that in RE teacher education developing pedagogical thinking should be accompanied with becoming aware of the role of personal life history and contextual situation play in the process of becoming a sound professional in RE. 相似文献

Immersion in time gives birth to consciousness, as well as conflict and torment. When human beings developed a sense of future, they also gained the ability to anticipate threats from nature or their fellow beings. They thereby created cultures that are bastions of survival, as well as places of poetry, art and religion where they could band together and reflect upon their common plight. The practice of psychoanalysis is in many ways a temporal process, a process of remembering, for owning and elaborating a past that gives us substance, thereby providing a basis for reflective consciousness. Stimulated by Freud's early writings, Lacan, Laplanche and their successors in particular have focussed extensively on time and psychoanalysis, and their views are a central point of this discussion. A substantial case study is offered that provides concrete examples of these perspectives. A multi‐faceted view of temporality emerges, one that is more syncopated than linear or teleological. In conclusion, I will briefly discuss recent findings in the neuroscience of memory and ‘time travel’ that underpin contemporary psychoanalytic ideas in surprising ways. It is important to remember that acceptance of the contradictory nature of temporal experience can open space for increased freedom and playfulness. 相似文献

Adolescents with low motor competence have diminished perceptions of their physical self and tend to avoid physical activities. This study examined the outcomes of an exercise intervention that focused on improving aerobic fitness, strength, and self-perceptions in the physical domain in adolescents with poor motor coordination. The sample included 35 adolescents with low motor competence, comprising boys (n = 25) and girls (n = 10) ranging in age from 13 to 17 years, who attended two sessions per week in the 13 week exercise intervention study (AMP it up). Physical self-perceptions were measured before and after the intervention using the Physical Self Perception Profile and Perceived Importance Profile. Significant improvements in perceived Physical Condition, Attractive Body and Physical Strength sub domain scores were identified between pre and post-test. Adjusting for age, gender, BMI and attendance, regression analyses revealed that Attractive Body was the strongest predictor of Physical Self Worth at pre-test, joined by Physical Condition at post-test. This exercise intervention had a positive impact on adolescent physical self-perceptions, in particular males, with improvements in those sub domains specifically related to the exercise program. Changes in specific aspects of Physical Self Worth can be facilitated by exercise interventions, after a relatively short period of time, in adolescents with poor motor coordination. 相似文献

Continuing advances in human ability to manipulate matter at the atomic and molecular levels (i.e. nanoscale science and engineering)
offer many previously unimagined possibilities for scientific discovery and technological development. Paralleling these advances
in the various science and engineering subdisciplines is the increasing realization that a number of associated social, ethical,
environmental, economic and legal dimensions also need to be explored. An important component of such exploration entails
the identification and analysis of the ways in which current and prospective researchers in these fields conceptualize these
dimensions of their work. Within the context of a National Science Foundation funded Research Experiences for Undergraduates
(REU) program in nanomaterials processing and characterization at the University of Central Florida (2002–2004), here I present
for discussion (i) details of a “nanotechnology ethics” seminar series developed specifically for students participating in
the program, and (ii) an analysis of students’ and participating research faculty’s perspectives concerning social and ethical
issues associated with nanotechnology research. I conclude with a brief discussion of implications presented by these issues
for general scientific literacy and public science education policy. 相似文献
