Accountability in a computerized society 总被引:2,自引:0,他引:2
Helen Nissenbaum PhD 《Science and engineering ethics》1996,2(1):25-42
This essay warns of eroding accountability in computerized societies. It argues that assumptions about computing and features
of situations in which computers are produced create barriers to accountability. Drawing on philosophical analyses of moral
blame and responsibility, four barriers are identified: 1) the problem of many hands, 2) the problem of bugs, 3) blaming the
computer, and 4) software ownership without liability. The paper concludes with ideas on how to reverse this trend.
Several people have contributed generously to this work. Michael Davis, Deborah G. Johnson, Arthur Kuflik, Pamela Samuelson,
Debra Satz, Richard De George, Larry May, and Dennis Thompson read drafts and made invaluable suggestions. Reviewers forScience and Engineering Ethics offered thorough and challenging commentary. An earlier version of the paper was presented at The American Philosophical
Association, Eastern Division Meeting, December 1993, where audience comments and questions led to clarification of several
key issues. 相似文献

Movement activity of a normal baboon and of a baboon with induced Parkinsonism by unilateral administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) was recorded by the Walter Reed Activity Monitor (or actigraph). Mean activity in the lesioned baboon was 41% less than that of the nonlesioned baboon measured over a 14-day period. In addition, the daily maximum activity value was significantly less in the MPTP-treated baboon. Moreover, resting and sleeping periods were 30% greater in the lesioned animal. The akinesia and resting and sleeping periods were displayed by the lesioned baboon throughout the day, whereas the control baboon showed them only at night. The data representing summarized movement activity are in accordance with observations of bradykinesia, hypokinesia, and akinesia of the MPTP-treated baboon. The actigraph was well tolerated by the animal because its small size and weight made it largely unobtrusive. We suggest that the actigraph is an appropriate device for measuring motor activity in nonhuman primates. 相似文献

This article is concerned with two recnet studies of the Family-of-Origin Scale (FOS), Gavin and Wamboldt (1992) and Ryan, Kawash, Fine, and Powel (1994). The external validity analyses conducted for the FOS in these studies assumed the scale to be a unidemsional measure. The present discussion centers on methodological decisions and interpretive strategies that may have prevented a more complete understanding of the scale's dimensional structure and theoretical meaning. It is concluded that a unidimensional view of the FOS is an oversimplification that is inconsistent with the available data. A case is made for a more comprehensive and technically adequate evaluation of the FOS. Specific suggestions are offered. 相似文献

This study examined therapeutic outcome for a group of 175 clinic families divided into levels of family competence and style, and, later, into seven clinical groupings. The division into these groups was based on the level of rated Competence and Style determined by using the Beavers Systems Model. Therapists also rated their level of Openness/Sharing Strategy, Power Differential, and Partnership with the family at the third session. Results indicate that more competent families who fared well in therapy had therapists who formed a partnership, disclosed strategy, and employed a minimal power differential with the family. The most disturbed families, and those with a Centrifugal style, did better with therapists employing a high power differential and lower levels of openness and partnership. The study also presented the distribution of individual diagnoses by family groups. Implications for family therapists, including the value of family assessment, are provided. 相似文献

Ninety soldiers with at least three months of combat exposure—60 injured soldiers (30 with permanent disabling and 30 with
nondisabling injuries), 30 noninjured soldiers and 30 healthy controls—were interviewed and investigated with physiological
(Prolactine, Cortisol, BP, Hb) and psychological tests (MMPI), IES-15 (Impact of Event Scale), PTSS (Post-Traumatic Symptom
Scale). Their was related injuries had a different effect on the physiological stress response of the soldiers as reflected
in the levels of prolactine, cortisol, hemoglobin and blood pressure.
In a report of personality characteristics of the same soldiers, we demonstrated that the experience of posttraumatic stress
was not dependent upon physical injury, but rather on the psychological appraisal of the situation. The results of the present
article confirm earlier findings that the relationship between physiological and psychological consequences of trauma are
complex, and that the perception of an event and the social context within which the traumatized soldier exists is as important
as the event itself. The physiological response to the trauma varied greatly among the soldiers regarding the psychosocial
impact of the consequence of the injury. So the anticipation of future possible trauma among less severely wounded soldiers
(expected to go back to war) was followed by pathological stress responses. Trauma seems to operate somewhat independently
from the overt conscious appraisal of the situation and relationship between psychological, psychosocial, and physiological
aspects are interrelated in a multifactorial way. An integrative approach is therefore of great importance in assessment as
well as in treatment of Posttraumatic Stress Disorder (PTSD).
Editorial Note This historical article is being published for the first time. It is based on the Ph.D. thesis of Dr. Harry
A. Teitelbaum for which he was awarded a doctorate by the University of Maryland in College Park in 1936. The dissertation
was stored prior to publication and was not rediscovered until 1997. Teitelbaum’s work was performed during the early days
of the development of knowledge regarding the mechanisms that regulate endocrine function. The understanding of the broad
capability of interactions among endocrine glands was evolving. It was a field that Teitelbaum contributed to for several
years, many of which were spent in collaboration with Horsley Gantt in his laboratory at Johns Hopkins. Although some of the
experimental strategies and some of the wording of the report seem quaint today, the contribution of Teitelbaum’s research
was solid and highly relevant to questions being asked at the time. 相似文献

This report aims to look at whether the results of a community survey of the prevalence of panic attacks and panic disorder could be influenced by a possible sex difference in the willingness to return screening questionnaires and to acknowledge psychiatric symptoms. The results suggest that men are less likely to return questionnaires, and that this effect is more marked in the younger age groups. This could indicate that an important group of people is being under-represented in prevalence figures for panic and possibly other psychiatric diagnoses. 相似文献

FM is a progressive aphasic patient whose language comprehension we studied over a 4-year period. We developed a variety of implicit and explicit tasks to chart progressive changes in the representation of linguistic knowledge (in particular, syntax and semantics) and the automatic and controlled processes which operate on that knowledge. The representation of FM's semantic knowledge remained essentially intact over the years, but she became increasingly impaired at combining the meanings of words. She also showed progressive impairments in the processes of syntactic combination. Thus, FM's disease resulted in a progressive inability to engage in those combinatorial processes necessary for the normal comprehension of a spoken utterance. This is not a selective deficit in the traditional sense of the term, since aspects of both syntax and semantics are implicated; but it is selective in the sense that other aspects of language comprehension remain intact. 相似文献

The author presents a model for research investigation and clinical use that deals with the interaction between cohesive and dispersive family of origin systems as reflected in marital and family interaction in nuclear families.From a paper presented at the tenth annual meeting of the American Family Therapy Association, June, 1988, Montreal, PQ, Canada. 相似文献
