Field theoretical approaches have become popular within economic sociology. Many even consider the notion of ?field“ a suitable alternative to the hegemonic paradigm of ?embeddedness“. This article outlines the epistemological potential of a field theoretical perspective by systematically comparing the approaches of Neil Fligstein and Pierre Bourdieu. By examining their respective contexts of emergence, their theoretical and methodological references, their research interests and their central concepts, both similarities and differences between the two approaches become visible. The resulting insights allow for a field theoretical and profoundly relational perspective on economic phenomena that might stimulate ongoing debates within economic sociology.  相似文献

The current article seeks to add to the quantitative approach to understanding terrorism by examining the logic underlying terrorist choice of targets and timing within the context of the Chechen–Russian conflict. Using data on Chechen rebel bombings in Chechnya and Russia from 1997–2003, the analysis revealed support for a logic underlying terrorist choice of targets. The results indicated that civilian targets were more likely to be targeted in Russia than in Chechnya, illustrating the importance of examining contextual effects within quantitative approaches to terrorism. The results also implicated an affect of weather and urbanization. Implications of the results and future directions for research are discussed.  相似文献

This paper considers the role of women in the Sydney branch of the New Theatre, from 1936 to 1969. In contrast to other gendered spaces found in the theatrical, industrial and political spheres, women held together the New Theatre. Not only did the theatre give opportunities to women as performers, but women embraced roles as directors, stage managers, writers, designers as well as holding elected offices. Drawing on oral histories and archival research, this study presents new scholarship on Australian women’s leadership in the theatre, arguing that their pattern of involvement was shaped by the voluntary nature of the work, the longevity of involvement, their political commitment and the theatre’s democratic structure. The blending of organisational and creative leadership created spaces for women’s voices in ways that were crucial to the long-term success of the Theatre, at a time when women were generally expected to focus on the domestic sphere.  相似文献

A simple, quick, selective, sensitive, and effective field-friendly method capable of being used by nonexperts has been developed for detecting mitragynine in Mitragyna speciosa (kratom) using surface-enhanced Raman spectroscopy (SERS). Over 100 samples and blanks (known to be either positive or negative for the presence of mitragynine) were examined in duplicate using five identical handheld Raman spectrometers, which provided a data set of over 1,000 examinations. Based on the results of these analyses, the method yielded a true-positive rate of 99.3%, a true-negative rate of 97.9%, a false-positive rate of 2.1%, and a false-negative rate of 0.7%. The average minimum detectable concentration (Cm) of mitragynine that reproducibly yielded a match for one of the library spectra on all five instruments was determined to be 342 ng/mL (ppb). This Cm value is a conservative estimate considering that the extraction process was not fully optimized by this study, which was not necessary since the Cm value achieved was well below typical mitragynine concentrations in kratom (1.3–2.3%). The method is ideal (i) for prioritizing samples for additional testing using other more time-consuming laboratory-based techniques needed to detect and quantify mitragynine and (ii) for field use at international mail facility (IMF) satellite laboratories to help interdict kratom and prevent this dangerous product from reaching the U.S. supply chain.  相似文献

Physiologic reactivity to racially rejecting images was assessed in 35 young adults (10 males, 25 female) from African-American backgrounds using the startle probe paradigm. In a laboratory setting, participants viewed 16 images depicting racial rejection, racial acceptance, nonracial negative, and nonracial positive themes. While viewing these images, startling bursts of noise were presented and the magnitude of the eyeblink responses were measured. Results supported an attentional mechanism which suggests that, while viewing both racially rejecting and nonracial positive images, individuals may be so absorbed in processing the images that they appear less distracted by the startling noise. However, these patterns were only found for participants low in racial regard. Young adults who felt positively about their racial background did not exhibit differential processing of startle stimuli as a function of slide themes. Race-rejection sensitivity did not moderate startle reactivity. Developmental implications, particularly in light of coping with racial discrimination, are discussed.
