对<系辞>等传中论及人性及其与天道之关系的文字,古今学者的理解各有心得.作者认为,行<系辞>论性语义为一阴一阳的运行变化称之为道,人从天道变化中得到了善,人性使天道赋予人的这种善得到了完成和显现.并且认为,<易传>、<中庸>、<孟子>实际都是认为"性自命出,命从天降"的,都是在人性与天道有一致性的意义上肯定人性善的,故否定<易传>有性善论,以为<易>、<庸>、<孟>的人性说致思路数不同的观点,都是不合实际的.作者又认为,将天道赋予人道正义的意义又返而以支撑人道原则,自<易传>已然,宋儒的天道性命学说与此是一脉相承的,故否定理学与先秦儒学的联系也是不合事实的.作者还认为,中国古代思想家宣扬性善论的主题是弘扬理性,强化人们对人道的自觉与自信,其中凝聚的积极善良的正气,乃是我们民族文化的元神.  相似文献

Artificial intelligence (AI) is a revolutionary and overwhelming technology that is yet to immature. While profoundly changing and shaping people and society, AI also splits into its own opposites and develops into a new external alien force. As the basic technical support of the entire society, intelligent technology entails the overt or covert domination of human beings, who are becoming the “vassals” and “slaves” of this high-speed intelligent social system. Various intelligent systems are constantly replacing human work, so that the “digital poor” gradually lose the opportunities and values offered by labor and hence are excluded by the global economic and social system, rendering their existence empty and absurd. The rapid development of intelligent robots has blurred the boundary between humans and machines and had a strong impact on the nature of man and his position as a conscious agent, making “What is man?” and the human-machine relationship prominent issues for our times, challenging the commonplaces of philosophy. We must face up to the existing or imminent risk of alienation, expand our theoretical horizons, innovate theories of alienation in the era of intelligence, take constructive action in terms of the construction of an ideal society and the evolution of man himself, build an ecological system for the joint evolution and growth of human beings and intelligent machines, and achieve liberty of man and the all-round and free development.  相似文献

The occupational injustices experienced by human trafficking survivors lead to immediate occupational performance deficits and promote long-term instability. Experience and previous patterns of behavior contribute to the deficits and instability. The occupational manifestations of complex trauma are reflected in the inability to participate in meaningful and necessary occupations. Occupational therapy intervention can be a means of empowering victims of human trafficking by using the occupational therapy process, occupational therapy theories, and models of practice. Occupational therapy practitioners can enable survivors to address the intrinsic and extrinsic barriers to achieving increased overall well-being and occupational performance.  相似文献

The pedigree chart is a cornerstone technology for producing bodies and value in livestock pure breeding. It organizes a cluster of processes, technologies, and discourses gathered under the rubric ‘pedigree practices’. Angus breeders commonly use artificial insemination to import performance ‘genetics’ into their herds, using the ‘expected progeny differences’ predicted by massive pedigree databases that now also contain phenotype data reported by cattle growers. Discourses of biological inheritance, good breeding, and pedigrees arose in the eighteenth century, concomitant with a fascination with races, species, and other biological kinds. A case study from Angus cattle breeding illustrates pedigree practices and the bodies made through them, showing how information and computing technologies, assisted reproductive technologies, and discourses of good breeding, purity, health, and disease leveraged a single bull and the two genetic diseases he carried into the pedigrees of up to 10% of the Angus herd. Technologies now widely used in human reproductive medicine were developed for use in livestock animals, especially cattle, extending a long relationship between cows and humans. While the development of these pedigree practices represents increased control over animal reproduction and bodies, it has also been instrumental in rendering all animal bodies, including human bodies, not only more technically but also more rhetorically available for reproductive interventions. These interventions may amplify anxieties about health, species, breed, and kin while also providing opportunities for contesting the boundaries of these nature–cultural categories.  相似文献

ABSTRACT

Human microbial communities are bodies of microorganisms that reside in or on different body parts. Importantly, they have been found to affect human health. However, scientific research on human microbial communities has created new challenges for human subject recruitment. First, individuals are asked to collect samples of bodily substances that can be seen as repulsive (e.g. feces and urine). Second, because scientists want to understand how human microbial communities evolve over time, individuals are asked to commit to a regular sample collection for extended periods of time. A longitudinal qualitative study of the work of scientists, physicians, research staff, and study coordinators involved in a human microbiome research project has found that these actors can bypass some aspects of these recruitment and retention challenges through ‘tuning work’. Tuning work is a collaborative process where professionals agree to adjust their practices towards shared goals. Such professionals reconfigure their work practices, personal routines, and the study protocol in an effort to obviate cultural taboos against handling bodily substances. The burden of long-term participation provides fewer opportunities for tuning work for these professionals, however. As such, long-term commitment by human subjects remains a recruitment and retention obstacle.  相似文献

Human systems are interacting with, and dependent on, the global ecosystem. These complex interconnected systems have to obey natural laws and system laws in order to remain viable in the long‐term. “Sustainable development” therefore has to adhere to certain principles and constraints which derive partially from physical conditions, partially from principles of (evolving) ecosystems, partially from principles applying to human systems with conscious actors and normative standards. Although “sustainable development” constrains the spectrum of permissible processes, it does not define a final steady state. The development process must be guided by reference to an ethical principle and to the balanced satisfaction of the basic orientors resulting from a system's interaction with its environment. The systems perspective required encompasses a wide range of scientific disciplines, for which a comprehensive bibliography is provided.  相似文献

To monopolize the scientific data gained by Japanese physicians and researchers from vivisections and other barbarous experiments performed on living humans in biological warfare programs such as Unit 731, immediately after the war the United States (US) government secretly granted those involved immunity from war crimes prosecution, withdrew vital information from the International Military Tribunal for the Far East, and publicly denounced otherwise irrefutable evidence from other sources such as the Russian Khabarovsk trial. Acting in “the national interest” and for the security of the US, authorities in the US tramped justice and morality, and engaged in what the English common law tradition clearly defines as “complicity after the fact.” To repair this historical injustice, the US government should issue an official apology and offer appropriate compensation for having covered up Japanese medical war crimes for six decades. To help prevent similar acts of aiding principal offender(s) in the future, international declarations or codes of human rights and medical ethics should include a clause banning any kind of complicity in any unethical medicine—whether before or after the fact—by any state or group for whatever reasons.  相似文献

In a recent article, Gross (2004) Gross, M. 2004. Doctors in the decent society: Torture, ill-treatment, and civic duty. Bioethics, 18(2): 181203. [INFOTRIEVE][CSA][CROSSREF] [Google Scholar] argues that physicians in decent societies have a civic duty to aid in the torturing of suspected terrorists during emergency conditions. The argument presupposes a communitarian society in which considerations of common good override questions of individual rights, but it is also utilitarian. In the event that there is a ticking bomb and no other alternative available for defusing it, torture must be used, and physicians must play their part. In an earlier article, Jones (1980) Jones, G. 1980. On the permissibility of torture. Journal of Medical Ethics, 6: 1113. [INFOTRIEVE][CSA] [Google Scholar] also argues in favour of physician participation in torture, going so far as to enthusiastically endorse the allocation of research resources as well to ensure that the ability to meet emergency situations is as efficient as scientifically possible. I argue against both these views and defend the absolute prohibition against torture generally, and against any participation by physicians in particular. I show that these arguments are incompatible with liberal or decent societies, and that the institutional requirements for making torture effective would constitute an unacceptable degradation both of medical ethics and practice, as well as of political institutions in general.  相似文献

The critical assumption of linearity between force and force variability for rapid movements made by Schmidt, Zelaznik, and Frank (1978) was studied in four experiments in the present study. The first three experiments extended earlier work showing linearity between force and force variability for submaximal force levels in static and dynamic contractions. However, at near-maximal force levels, when force was increased, force variability leveled off and then decreased in both static and dynamic conditions. A fourth experiment using the rapid-timing paradigm showed that increased submaximal loads on the movement produced slight decreases in VE. But when the loads were larger, where force and force variability were no longer linearly related, increased load led to larger decreases in VE. These observations led to the hypothesis that VEt is linearly related to the ratio of force variability to force; data from two experiments are presented that support this idea. The motor-output variability theory seems to hold for a wide range of sub-maximal force values, but needs modification for those conditions where near-maximal forces are required.  相似文献

Gravity reduction affects the energetics and natural speed of walking and running. But, it is less clear how segmental coordination is altered. Various devices have been developed in the past to study locomotion in simulated reduced gravity. However, most of these devices unload only the body center of mass. The authors reduced the effective gravity acting on the stance or swing leg to 0.16g using different simulators. Locomotion under these conditions was associated with a reduction in the foot velocity and significant changes in angular motion. Moreover, when simulated reduced gravity directly affected the swing limb, it resulted in significantly slower swing and longer foot excursions, suggesting an important role of the swing phase dynamics in shaping locomotor patterns.  相似文献
