The article attempts to identify and account for changes in local social relations which accompanied economic and social‐structural change in early‐modern England. An overview of recent findings is provided to highlight both the enduring characteristics of rural society in the period and the elements of change. Next it is argued that the aspects of change can be interpreted as a process of incorporation with economic, administrative and cultural dimensions which had the ultimate effect of promoting integration nationally, but differentiation locally. Particular illustration of this general argument is given in an examination of change in the Essex village of Terling.  相似文献

X-ray photoelectron spectroscopy (XPS) is a widely used technique to characterize the surface chemistry of materials. It plays a crucial role in accessing qualitative and quantitative information and in detecting the presence of chemical functional groups on the surface of any material. The forensic methods available to detect and identify elements and organic/inorganic compounds are often destructive, so evidence cannot be re-analyzed. However, XPS allows rapid analysis of samples without damaging them. Recently, an increasing number of forensic researchers have begun to study certain chemical information on fingermarks. In this study, the authors aimed to present the applicability and power of XPS imaging in fingermark analysis which can also provide specific information about the fingermark chemical composition. Herein, monochromated X-ray (Al Kα) spot size was fixed at 50 μm. XPS mapping resulted in the acquisition of spectra at each pixel, in an array of 41 × 30 pixels with a step size of 50 μm. Then, a simple discussion has been made about how the scanned surface spectrum and basic snapshot spectra are used to identify different components at a fingertip of a scanned surface area (~3 mm2). Hence, a fingermark pattern contaminated with caffeine, TiO2, and Pb/PbO deposited on the silicon wafer can be chemically mapped and visualized by XPS using principal component analysis (PCA). Thus, the present study showed the possible applicability of XPS for the identification of illicit drugs of abuse, gunshot residue, and skin care products on latent fingermark by mimicking a crime scene evidence.  相似文献

Experiences with racism are a common occurrence for African American youth and may result in negative self perceptions relevant for the experience of depressive symptoms. This study examined the longitudinal association between perceptions of racism and depressive symptoms, and whether perceived academic or social control mediated this association, in a community epidemiologically-defined sample of urban African American adolescents (N = 500; 46.4% female). Structural equation modeling revealed that experiences with racism were associated with low perceived academic control, which in turn was associated with increased depressive symptoms. Findings suggest that experiences with racism can have long lasting effects for African American youth’s depressive symptoms, and highlight the detrimental effects of experiences with racism for perceptions of control in the academic domain. Implications for intervention are discussed.

This paper seeks to contribute to the debate over the efficacy of voluntary agreements versus regulation, and uses a study of the Livable Housing Design initiative to deliver voluntarily new‐built accessible housing in Australia. We first probe why regulation has become such a significant component of government policy making, and then ask why political campaigns focus on this issue as a strategy for reform. We refer to research by disability activists, which claims that the voluntary approach has failed and regulation is necessary. Amongst our conclusions are: (1) that the disjuncture between policy rhetoric and outcome can be attributed to the power of lobbyists, reliance on the private market to address inequality, and antipathy to regulatory enforcement; and (2) that there is a need for greater interrogation of the language deployed in policy texts to identify whether they are crafted to maintain the government's legitimacy or to deliver purposeful change.  相似文献

The research reported here is an analysis of the evolution of the relationships that comprise a single public health network, focusing especially on the position of the network administrative organization (Provan and Kenis 2008 Provan, K. G. and P. Kenis. 2008. “Modes of Network Governance: Structure, Management, and Effectiveness.” Journal of Public Administration Research and Theory 18(2): 229252.[Crossref], [Web of Science ®] [Google Scholar]) in the flow of knowledge among a large number of organizations providing similar services. Our study examines the North American Quitline Consortium (NAQC), a multi-sector network that spans the US and Canada and whose members provide telephone-based tobacco cessation services to anyone interested in quitting smoking. Data were collected using web-based surveys at three different points of time. Implications are discussed for network organizing, for both theory and practice, focusing especially on the importance of the network administrative organization in shaping the evolution of the whole network information flow.  相似文献
