Depicting a Liminal Position in Ethnomethodology, Conversation Analysis and Membership Categorization Analysis: The Work of Rod Watson 总被引:1,自引:0,他引:1
This paper provides a provisional examination of Rod Watson's work and contributions to EM/CA/MCA, in part through a critique of misrepresentations of his arguments in secondary accounts of his work. The form of these misrepresentations includes adumbration and traducement of his arguments. Focusing on the reflexivity of category and sequence and turn-generated categories, we suggest that his analytic position within ethnomethodological fields is unique and remarkable, yet largely unacknowledged. We argue that a re-examination of the body of Watson's work makes relevant explicit and appropriate acknowledgement of his contributions through his unconventional approach and his extension of prior works in novel and stimulating directions. 相似文献

Although there has been a rapid increase in funding and attention to after-school programs, there is little understanding of how after-school programs impact children's developmental trajectories. The heterogeneity of American children makes it very unlikely that all children need after-school programming or that there is but one brand of after-school programming suitable for all youth. We discuss the numerous developmental and contextual factors that may influence which children benefit most from after-school programs as well as the nature of the after-school programs most beneficial to children's needs. The value of utilizing an ecological and developmental perspective to after-school program evaluation are presented, including the need for improved research designs and more detailed analyses of program type and services as well as a more complete determination of which children benefit the most from after-school participation. 相似文献

Mass casualty attacks in recent years have demonstrated the need to include “evil intent” as a design consideration. Three
recent actual or potential weapons of mass destruction (WMD) attacks did not involve nuclear bombs or other devices designed
as weapons, but rather benign objects used with evil intent. Just as unplanned events such as hurricanes, earthquakes, fires,
and user misuse have been codified into design requirements based on the likelihood and potential impact of the event, “evil
intent” has to become part of the design process for buildings, vehicles, equipment, and other items. The endstate should
be reasonable additions to existing codes and standards such that it is clear what is and is not designed for. In the absence
of specific design guidance, professionals with appropriate expertise can assess potential for “evil intent” and provide recommendations
to design out or warn against this potential harm to public safety, particularly when codified requirements are not present.
An earlier version of this paper was presented at the “Ethics and Social Responsibility in Engineering and Technology” meeting,
New Orleans, 2003.
Author Note: Bart Kemper, PE, is the principal engineer for Kemper Imageering, Inc. A significant portion of his work has been involved

This paper offers commentaries on Pate and Kohout’s (2005) report of data from the 1997 and 2003 surveys of psychologists in medical school settings. The commentaries reflect upon the significance of the survey findings and implications for psychology’s role in medical school and academic health science settings. Though the response rate to the survey was disappointing, the data indicate that psychologists are moving up in academic rank, and have made substantial gains in salary. The data also indicate that among psychologists who are medical staff members, who constitute half the 2003 sample, an increasing proportion are functioning autonomously as reflected in gains in the percentage having admitting privileges, staff voting privileges, and authority to write orders. Research continues to be a major focus for psychologists in academic medical centers. Overall, the findings indicate that psychologists can have productive, satisfying careers in medical school/academic health center settings—though there is one troubling sign, a sizeable drop in the number of positions being created for younger, more recently trained psychologists. Methodological enhancements are described that could improve the quality, scope, and usefulness of data from future studies, both for understanding long-term trends and for conducting salary negotiations. High quality data provide a solid foundation for advocating for psychologists’ full participation in the life of medical schools and academic health centers. 相似文献

Multicultural societies are far more likely than others to include minorities committed to the pursuit of practices that offend
the majority, and treating the cultural commitments of all citizens fairly will require some set of guiding principles to
distinguish tolerable ‘cultural controversies’ from intolerable ones. This paper does not directly address the moral question at stake here (i.e. demarcating the limits of toleration) but rather seeks to provide a politically justifiable normative argument to explain when tolerant restraint is necessary, permissible or prohibited. This argument emerges from
a concern to treat the cultural commitments of all citizens fairly. In turn, the argument indicates a potential reconciliation
of the ‘politics of toleration’ with the ‘politics of respect’.

Jürgen Habermas’s discourse-theoretic reconstruction of the normative foundations of democracy assumes the formal separation
of democratic political practice from the economic system. Democratic autonomy presupposes a vital public sphere protected
by a complex schedule of individual rights. These rights are supposed to secure the formal and material conditions for democratic
freedom. However, because Habermas argues that the economy must be left to function according to endogenous market dynamics,
he accepts as a condition of democracy (the formal separation of spheres) a social structure that is in fact anti-democratic.
The value of self-determination that Habermas’s theory of democracy presupposes is contradicted by the actual operations of
capitalist markets. Further democratic development demands that the steering mechanisms of the capitalist market be challenged
by self-organizing civic movements. 相似文献

On August 22, 2005 the U.S. Environmental Protection Agency issued proposed new regulations for radiation releases from the
planned permanent U.S. nuclear-waste repository in Yucca Mountain, Nevada. The goal of the new standards is to provide public-health
protection for the next million years — even though everyone admits that the radioactive wastes will leak. Regulations now
guarantee individual and equal protection against all radiation exposures above the legal limit. Instead E.P.A. recommended
different radiation exposure-limits for different time periods. It also recommended using only the arithmetic mean of the
dose distribution, to assess regulatory compliance during one time period, but using only the median dose to assess compliance
during another period. This piece argues that these two changes — in exposure-limits and in methods of assessing regulatory
compliance — have at least four disturbing consequences. The changes would threaten equal protection, ignore the needs of
the most vulnerable, allow many fatal exposures, and sanction scientifically flawed dose calculations. 相似文献

School-based mental health (SBMH) programs and services are growing progressively in the United States for many reasons. However,
the SBMH field is young and tenuously supported, and challenges are being confronted on many levels. There are major needs
to continue to bring research-supported interventions into schools, and to better equip educators and mental health programs
and staff in schools to function effectively. Articles in this special issue present the many challenges well and point to
important directions for advancing SBMH. To truly advance the field a Public Mental Health Promotion approach is needed. Elements of this approach, in advancing training, quality assessment and improvement (including empirically
supported practice), and advocacy and policy influence are discussed, as are strategic connections to the Community Science
perspective and to the development of a growing Community of Practice in SBMH. 相似文献

Psychoanalytic and psychiatric perspectives on children who threaten to kill others are reviewed in the context of the need for an interdisciplinary approach to the problem. Converging technologies derived from a psychoanalytically informed social systems model are compared to law enforcement approaches, psychoanalytic understanding of the individual dynamics of the child, and empirical research on conduct disordered adolescents. The interdisciplinary orientation of a broadly trained community psychoanalyst allows a unique contribution when trying to distinguish adolescents who make a threat from those who pose a threat. Case vignettes are used to illustrate the hypotheses. 相似文献

The effects of self-set goals and public posting on athletic performance of 5 collegiate football players was studied. All players were linebackers on a National Association of Intercollegiate Athletics Division II football team. The dependent variables were the percentage of correct occasions when the linebacker (a) positioned himself to cover a specified area on the field during a pass or from the line of scrimmage during a run; (b) moved to the correct position in response to the positioning of the offense; and (c) tackled and stopped the progress of the ball carrier. A multiple baseline design across behaviors showed an immediate increase in the practice performance of the players and a corresponding increase in game performance following introduction of the independent variable. This study extends research using public posting in sport by demonstrating the effects of player-determined goals and public posting of goal attainment. 相似文献
