企业诚信及其实现机制——以“海尔”为例   总被引:5,自引:0,他引:5  
诚信是伦理关系范畴,作为企业来说,既要诚信于顾客,也要诚信于内部员工和外部同行。并且,企业诚信品质的形成和企业诚信的实现不是一蹴而就的,它需要企业内外部各种力量和手段的协调和支撑。  相似文献

“善良意志”是康德伦理学的核心概念,他将善良意志提升到道德领域的至善地位,从而确定了道德的纯粹性。他还借助善良意志划分了善与恶的界限,指明了责任作为检验善恶的标准,将传统德性论的品质和功用主义的幸福都排除在道德领域之外。由此,康德还将伦理与道德的界限做了区分,他强调伦理与道德各自明确自身的权责,从而充分发挥各自的作用。  相似文献

Rough and tumble (R&T) play is a unique set of behaviors that can be reliably distinguished from aggression and other childhood activities. Although it may be the most fundamental form of play, it has received comparatively little experimental attention in the human species. Forty children, ages three to six, were allowed to play in pairs (10 male pairs, 10 female pairs) during a 30 minute videotaped session with no toys available while music played in the background during every other five‐minute time period. The incidence frequency of children's play and related behavioral activities were scored using 20 behavioral categories. The major findings show only modest gender differences in the frequency of play behaviors in such controlled social encounters; the main difference is that boys engaged in slightly more physical play solicitations than girls. Music facilitated General Motor Activities (e.g., Running and Walking behaviors), but not specific R&T play actions (e.g., Wrestling, Ventral and Dorsal contacts). Finally, most play behaviors as well as general activities declined systematically over the course of each recording session. This experiment highlights how human social play can be systematically studied in a controlled laboratory setting. Aggr. Behav. 29:539–551, 2003. © 2003 Wiley‐Liss, Inc.  相似文献

Most recent writing linking science and literature has concerned itself with challenges to the epistemological status of scientific knowledge in an attempt to demonstrate its contingency, arguing in the more radical efforts that the structures of science are no more than useful fictions. This essay also includes an epistemological comparison between science and literature, but instead of making grand or meta–statements about the nature of knowing generally in the two fields, mine is a much narrower aim. My exploration entails two tasks. First, I provide a close–up look at a particular type of experiment, called the delayed–choice experiment, which clearly reveals the strangeness of the quantum world. In connection with this experiment, I discuss wave functions—mathematical expressions used by physicists to describe quantum behavior and predict the outcome of experiments involving quanta. Second, I look at Walt Whitman's “Song of Myself” focusing on the meaning of the “self” in the poem. My aim is to treat the object of study in each field as a “text” and to assert and demonstrate a parallel in the strategies of thought and response between physicists (“readers”) pondering the meaning and status of a wave function and poem readers pondering the meaning and status of the poem's self. In Whitman's “Song” we find an attempt to understand complex aspects of human experience that are said to transcend ordinary reality, an effort for which I believe there are parallels in the attempts of modern physicists to understand complex, nonintuitive aspects of the subatomic world. While not making the kind of broad claims eschewed above, I do suggest that this focused study has interesting implications since both the wave function and the poem's self force their respective sets of “readers” to confront questions of ultimacy—to consider, that is, epistemological and ontological issues of more than passing interest to students of science as well as those of metaphysics and theology.  相似文献

Is reductionism simply a methodology that has allowed science to progress to its current state (methodological reductionism), or does this methodology indicate something more, that the material universe is determined in full by its smallest components (ontological or causal reductionism)? Such questions lie at the heart of much of the contemporary religion–science dialogue. In this essay I suggest that the position articulated by philosopher–theologian Bernard Lonergan is particularly suitable for dealing with these questions. For Lonergan, the criterion of the real is simply its verified intelligibility and not its imaginability. Each of the various levels of reality, as studied in sciences such as physics, chemistry, biology, and sensitive and rational psychology, consists of an intelligible integration of what on the lower level would be simply random occurrences. The things studied by the various sciences (atoms, molecules, cellular organisms, animals, human persons, and so on) are intelligible unities, and no one level is somehow more real than any other. I argue that such a scheme, while seeming somewhat counterintuitive, is best able to deal with the multilayered reality of the contemporary physical and life sciences and provide an opening to the richness of the social sciences and the achievements of human culture.  相似文献

Abstract. In his book God After Darwin John Haught provides a useful categorization of theological approaches to evolution: some theologians actively oppose Darwinian evolution, another group maintains that science and religion have nothing to say to one another, and a third seeks to engage evolution. Haught wishes to pursue the third way. But many theological attempts to talk about divine action in the world, including divine involvement in the process of evolution, run afoul of the scientific principle of the conservation of matter‐energy. Haught's reliance on the now‐familiar notion that information can have causal efficacy does not in fact escape this difficulty. I suggest a fourth approach, represented by a constructive reading of Paul Tillich's theology. The central argument is that Tillich offers a way of taking Darwinian evolution up into one's ultimate concern without claiming that God has any causal relation to evolution. God provides no historical telos for evolution, but rather a “depth teleology” that springs from the manner in which God, as the depth of the structure of finite being, is the object of Christian faith.  相似文献

The prophets Nathan (2 Samuel 12:1–15) and John the Baptist (Mark 6:16–28) had comparable tasks before them: to convince their respective kings about the wrongs of taking somebody else's wife and marrying her. Nathan succeeded, while John failed and furthermore lost his life. What made the difference? One possible explanation is that Nathan proceeded in two steps: (1) Tell an interesting, nonthreatening story that nevertheless makes the point at issue; (2) transfer that message to the case at hand. In contrast, John used a direct approach, which raised apprehension, even fear (on the part of Herodias, the woman involved), and led to failure. That lesson has wider applications, as illustrated here for teaching the biblical Genesis narration. The other ingredient in this teaching is relational and contextual reasoning (RCR), the use of which is also indicated for other issues besides teaching Genesis.  相似文献

The purpose of this study was to complete a mental health staff opinion survey to identify patient and staff characteristics associated with staff assault and injury in psychiatric treatment settings and to develop a model of prediction for staff assault and injury utilizing these survey variables. The data consisted of opinion surveys sent to staff of 15 child, adolescent, and adult psychiatry inpatient units in the United States. Multivariate logistic regression was used to determine the level of assault and staff‐reported injury prediction that could be obtained from the staff‐completed opinion survey. Responses indicated a high prevalence of reported aggression, with 62.3% of staff endorsing verbal and physical aggression, property destruction, and self‐injurious behavior as being prevalent at their site, whereas only 4.1% rated none of these as prevalent. Staff working with children and adolescents in settings with high rates of psychiatric diagnoses reported increased frequency of assault and injury compared with those working with adults. Younger, less experienced staff reported higher rates of assault and injury. Staff working with female patients reported similar rates of assault and injury to those working with males. A logistic regression analysis using staff‐reported survey results of both staff and patient characteristics predicted assault correctly 73.7% of the time and injury 66.1% of the time. Resources for violence prevention and staff training programs in violence prevention are needed in child and adolescent psychiatry wards. Results are consistent with theories emphasizing the importance of negative emotions and affects, impulsivity, and frustration in goal‐directed activities in human aggression. Aggr.
