Funding agencies in Canada are attempting to break down the organizational boundaries between disciplines to promote interdisciplinary
research and foster the integration of the social sciences into the health research field. This paper explores the extent
to which biomedical and clinician scientists’ perceptions of social science research operate as a cultural boundary to the
inclusion of social scientists into this field. Results indicated that cultural boundaries may impede social scientists’ entry
into the health research field through three modalities: (1) biomedical and clinician scientists’ unfavourable and ambivalent
posture towards social science research; (2) their opposition to a resource increase for the social sciences; and (3) clinician
scientists procedural assessment criteria for social science. The paper also discusses the merits and limitations of Tom Gieryn’s
concept of boundary-work for studying social dynamics within the field of science.

This study considers a frailty duration approach to modelling the life-length of a sample of 360 films that went into wide
release at the Australian box office from 1 January 2000 to 31 December 2005. The analysis extends previous research by
considering a range of film-specific covariates relating to distribution, production, consumer signals, and weekly performance.
In particular, it is shown that film success (defined in a duration context) responds to previewing, advertising, critical
reviews, and US box office—but not to production budget, star power or opening-week screens. The study also reveals that it
is appropriate to account for unobservable heterogeneity between films in the choice of empirical methodology. 相似文献

The marine environment includes the nutrient-rich coastal waters, relatively nutrient-poor open oceanic waters, coral reef
atolls, metal-rich hydrothermal vent fluids with temperatures of 200–350°C, cold-seeps, estuaries, mangrove swamps, intertidal
beaches and rocky shores. Oceans are home to some of themost diverse and unique life forms. This article is an attempt to
introduce some of the fundamentals of biologicaloceanography andmarine biologyto describe life in the sea. 相似文献

The study's purpose was to identify the mediating role of intention and the stages of change (SOC) in physical activity (PA) over a 6-month period using two models (theory of planned behavior [TPB] and TPB/SOC). Participants were 143 adults with physical disabilities (70.68% response rate; M age = 46.03). The TPB constructs, SOC (time 1), and PA (time 2) were assessed using standardized self-report questionnaires. Based on path analyses, attitude had the highest effect on intention and SOC followed by perceived behavioral control within both well-fit models. The variance in PA explained by the first (TPB) and second (TPB/SOC) models was 16% and 28% respectively. In the just identified model of TPB/SOC, the direct effect of SOC on physical activity remained strong (gamma(soc.pa) = .45) and SOC approached full mediation through attitude. Health promotion interventions need to include both intention and behavior elements (SOC) reinforcing increased PA value and barrier elimination. 相似文献

The article tests a couple of hypotheses relating to markets where demand is not taken as a given, but subject to sophisticated
and encompassing price-building strategies. The study uses a data set that provides quoted dealer prices for medium-sized
works of 100 leading visual artists from 1970 to 2004. These data are compared with auction price results for works by the
same artists. The study reports significant discrepancies with respect to the relationship between the age of artists and
prices paid for their works in the two markets, and with respect to general price developments in the two markets as measured
by indices.
