Going after means taking up a position with regard to something and the active pursuit of that same thing. It is the critical move par excellence , but also an act of appropriation. This essay suspends the urge to go after in preference for an exploration of the trajectory of that body of texts known as the sociology of translation. The figure of the perpetuum mobile is put into circulation through these texts in order to trace some of their more unusual and unfamiliar connections. These include a whole series of parallels with seventeenth century classical philosophy and with nineteenth century 'social energetics'. Connections are drawn out by using three 'test signals', which are sent on through the ANT canon: substance, force and time. Pivotal to each is the sense of how very different events and apparently diverse territories can be brought into contiguity, or folded up together. This contiguity needs to be performed rather than described , placed in translation rather than simply presented . The chapter concludes by tracing a way from the strange folds of ANT to the equally peculiar forms of early Psychology. 相似文献

Current status data arise in studies where the target measurement is the time of occurrence of some event, but observations
are limited to indicators of whether or not the event has occurred at the time the sample is collected - only the current
status of each individual with respect to event occurrence is observed. Examples of such data arise in several fields, including
demography, epidemiology, econometrics and bioassay. Although estimation of the marginal distribution of times of event occurrence
is well understood, techniques for incorporating covariate information are not well developed. This paper proposes a semiparametric
approach to estimation for regression models of current status data, using techniques from generalized additive modeling and
isotonic regression. This procedure provides simultaneous estimates of the baseline distribution of event times and covariate
effects. No parametric assumptions about the form of the baseline distribution are required. The results are illustrated using
data from a demographic survey of breastfeeding practices in developing countries, and from an epidemiological study of heterosexual
Human Immunodeficiency Virus (HIV) transmission.

This article focuses on exploring what technology scholars and students of management of technology stand to benefit most by foraging through the history of technology. In order to show how historical sensitivity could sharpen scholarship, three strategies for complicating the simple are drawn from the historian's toolkit. Implications for research in technology and innovation management are discussed. 相似文献

Differences in the treatment of involvement in the human resource management (HRM)–performance research stream have been underplayed, as commentaries concentrate on showing that HRM produces a performance premium, and more recently on exploring the mechanisms explaining this. This paper first identifies the two initial concerns of the research stream – the value of employee involvement and the holistic treatment of HRM – and the way these are joined to present a unified view of the area. It then reviews the studies, confirming that involvement has been underplayed or neglected completely, and is only prioritized in a minority. A divide is identified between HRM as an orientation towards fostering employee involvement – seen as a managerial philosophy – and as a technology – a set of practices constituting high‐performance work systems. The paper then argues that acknowledgement of this divide matters, and concludes by drawing out some implications for how we should progress the research stream. 相似文献

Value at risk and expected shortfall are the two most popular measures of financial risk. But the available R packages for their computation are limited. Here, we introduce an R contributed package written by the authors. It computes the two measures for over 100 parametric distributions, including all commonly known distributions. We expect that the R package could be useful to researchers and to the financial community. 相似文献

This study used observations from the 1985 Massachusetts malpractice insurance rate hearings, semistructured interviews conducted in 1985–1986, a survey of Massachusetts physicians in February 1988, and newspaper reports from theBoston Globe. Physicians and the Massachusetts Medical Society have promoted the medical malpractice crisis as an economic one. The after-expense income of most physicians, however, has remained relatively constant. The more serious threat to physicians appears to be the reduction of their autonomy. It is concluded that the medical malpractice crisis has been socially constructed in economic rather than autonomy terms because, traditionally, economics has been a more acceptable basis for labor unrest in the United States. Constructing malpractice as an economic crisis presents a more viable argument for stemming social change adverse to the medical profession.An earlier version of this paper was presented at the 57th annual meeting of the Eastern Sociological Society, May 1987, Boston, Massachusetts. 相似文献

This article examines the effects of English proficiency and female education on cumulative and recent fertility within the Mexican-origin population in the U.S. To ascertain whether the cultural or the human capital aspects of linguistic variables have the greater salience for fertility behavior, fertility patterns of bilingual women are compared with those of monolingual women speaking English or Spanish. Using the 1980 U.S. Census 5 percent Public Use Microdata Sample for ever-married Mexican-origin women aged 15-44, we find that for almost all age cohorts, the effects of English proficiency are negative and increase with rising education. The strength of the interaction is greater in younger age groups. Greater English proficiency is also associated with a more negative impact of education for native- than foreign-born women. Overall, the influence of "opportunity cost," as opposed to cultural factors, is more important in shaping the fertility behavior of these women. 相似文献
