This article is a discussion of reality construction of dependency-bonds by oppressed groups with an oppressor. In this model of dependency-bond processes, it is suggested that oppressed people, when possible, attempt to translate the power-dependency equation from one of coercion and objectification into a less onerous, more agreeable bond; that is, subordinate people strive to establish and to reinforce dependency relationships as a strategy of control whereby the power of superiors is deflected from coercive measures against them into lines of obligation toward them. It is further proposed that the secondary effects of this process include the social construction of subordinate identity as dependent and of subordinate place as dependent place.  相似文献

Silphids in urban forests: Diversity and function   总被引:2,自引:0,他引:2  
Wolf  Jordan M.  Gibbs  James P. 《Urban Ecosystems》2004,7(4):371-384
Many ecologists have examined the process of how urbanization reduces biological diversity but rarely have its ecological consequences been assessed. We studied forest-dwelling burying beetles (Coleoptera: Silphidae)—a guild of insects that requires carrion to complete their life cycles—along an urban-rural gradient of land use in Maryland. Our objective was to determine how forest fragmentation associated with urbanization affects (1) beetle community diversity and structure and (2) the ecological function provided by these insects, that is, decomposition of vertebrate carcasses. Forest fragmentation strongly reduced burying beetle diversity and abundance, and did so far more pervasively than urbanization of the surrounding landscape. The likelihood that beetles interred experimental baits was a direct, positive function of burying beetle diversity. We conclude that loss of burying beetle diversity resulting from forest fragmentation could have important ecological consequences in urban forests.  相似文献

Several colorectal cancer (CRC) screening models have been developed describing the progression of adenomas to CRC. Currently, there is increasing evidence that serrated lesions can also develop into CRC. It is not clear whether screening tests have the same test characteristics for serrated lesions as for adenomas, but lower sensitivities have been suggested. Models that ignore this type of colorectal lesions may provide overly optimistic predictions of the screen‐induced reduction in CRC incidence. To address this issue, we have developed the Adenoma and Serrated pathway to Colorectal CAncer (ASCCA) model that includes the adenoma‐carcinoma pathway and the serrated pathway to CRC as well as characteristics of colorectal lesions. The model structure and the calibration procedure are described in detail. Calibration resulted in 19 parameter sets for the adenoma‐carcinoma pathway and 13 for the serrated pathway that match the age‐ and sex‐specific adenoma and serrated lesion prevalence in the COlonoscopy versus COlonography Screening (COCOS) trial, Dutch CRC incidence and mortality rates, and a number of other intermediate outcomes concerning characteristics of colorectal lesions. As an example, we simulated outcomes for a biennial fecal immunochemical test screening program and a hypothetical one‐time colonoscopy screening program. Inclusion of the serrated pathway influenced the predicted effectiveness of screening when serrated lesions are associated with lower screening test sensitivity or when they are not removed. To our knowledge, this is the first model that explicitly includes the serrated pathway and characteristics of colorectal lesions. It is suitable for the evaluation of the (cost)effectiveness of potential screening strategies for CRC.  相似文献

Embeddedness theory stresses the importance of concrete personal relations and networks of relations in economic life. Recent sociological research shows that effects of embeddedness may differ between social settings, and recent experimental anthropological findings reveal that levels of cooperation and norm-enforcement differ between cultural settings. We extent these lines of research by examining whether effects of embeddedness on trust differ between two social settings, namely Germany and The Netherlands. To examine our research question we use a comprehensive database consisting of 925 Dutch and 929 German purchase transactions. We find evidence that some aspects of social embeddedness indeed have different effects in the two countries. In Germany sharing a history of previous transaction and the existence of alternative partners had a larger effect on trust than in the Netherlands. We offer a potential explanation and discuss its implications for future research on embeddedness.  相似文献

The purpose of this brief is to present several case vignettes that illustrate omissions in the investigation of elder deaths. These vignettes demonstrate the need for a standardized approach in the conduct of medicolegal investigations of fatal elder abuse. For each of the described oversights, a recommendation is offered to address the gap in investigation processes, which in turn could improve the determination of cause and manner of elder death. Inherent limitations of resources and practical realities of death investigation are discussed and recommendations are made for future research. Viewed broadly, deficiencies in elder death investigations can lead to the underreporting of elder abuse and the reduction of legal options for victims, which may reflect a systemic pattern of social injustice.  相似文献

We deal with the double sampling plans by variables proposed by Bowker and Goode (Sampling Inspection by Variables, McGraw–Hill, New York, 1952) when the standard deviation is unknown. Using the procedure for the calculation of the OC given by Krumbholz and Rohr (Allg. Stat. Arch. 90:233–251, 2006), we present an optimization algorithm allowing to determine the ASN Minimax plan. This plan, among all double plans satisfying the classical two-point-condition on the OC, has the minimal ASN maximum.  相似文献

The effects of different sales strategies on consumer product evaluation were investigated. It was expected that direct product experience could decrease economic product valuation. Experiments 1 and 2 studied the effects of product trials and money-back guarantees on consumer willingness to pay (WTP). It appeared that WTP was significantly lower after a product trial than with a money-back guarantee or normal sale. In Experiment 3 a structural equation model showed that product trials had a positive effect on attitude toward the product. Also, a negative effect on WTP was found when the effect was measured directly, but a positive effect when the effect was measured indirectly (through attitude).  相似文献
