本文致力于厘清关于市镇研究的理论传统,对明清以来市镇的演变在经济、社会和政治等多个层面进行考察。从经济层面看,市镇是连接地方性市场和世界体系的节点,并越来越具有超层级、跨区域和金融化的特点;从社会层面看,市镇是有层级、有组织的,并具有很强的包容性;从政治层面看,它是地方自治化和国家政权建设的着力点。在社会结构中的中间性质是市镇的本质特征。社会学对于市镇的研究必须将其看作一种总体性的社会事实,在对生命体验、生活智慧、伦理道德、乡风民俗等民情因素进行调查研究的前提下,考察其与具体制度和社会结构之间的关联。 相似文献

The roles of small congregations and their social impacts are well known, but few theoretical studies investigate megachurch congregations. These mammoth organizations have the potential for advancing social good, but minimal research specifically focuses on the activities of these congregations in economic development (ED). This study addresses this dearth of information by answering the following research questions: (a) In what ways are megachurches involved in ED activities? (b) Who benefits from these programs and how are the programs offered? and (c) What factors influence megachurches to offer ED activities? We frame our investigation using both demand‐ and supply‐side arguments from Frumkin's (2002) model of nonprofit and voluntary action. Online survey data and follow‐up interviews with 42 megachurch leaders in the Dallas/Fort Worth and greater Houston areas show that megachurches are implementing ED activities in alignment with demand‐side explanations, especially when advancing opportunities for the unemployed and underemployed. However, supply‐side arguments provide more explanatory power, indicating that volunteer engagement with ED activities plays a significant role in the provision of ED services through megachurches. Our study offers a better understanding of why megachurches carry out ED activities with considerable attention devoted to how megachurches partner with other congregations, nonprofits, and government entities to encourage economic growth and improve the economic well‐being of community members. 相似文献

Data collected in various scientific fields are count data. One way to analyze such data is to compare the individual levels of the factor treatment using multiple comparisons. However, the measured individuals are often clustered – e.g. according to litter or rearing. This must be considered when estimating the parameters by a repeated measurement model. In addition, ignoring the overdispersion to which count data is prone leads to an increase of the type one error rate. We carry out simulation studies using several different data settings and compare different multiple contrast tests with parameter estimates from generalized estimation equations and generalized linear mixed models in order to observe coverage and rejection probabilities. We generate overdispersed, clustered count data in small samples as can be observed in many biological settings. We have found that the generalized estimation equations outperform generalized linear mixed models if the variance-sandwich estimator is correctly specified. Furthermore, generalized linear mixed models show problems with the convergence rate under certain data settings, but there are model implementations with lower implications exists. Finally, we use an example of genetic data to demonstrate the application of the multiple contrast test and the problems of ignoring strong overdispersion. 相似文献

In high-dimensional linear regression, the dimension of variables is always greater than the sample size. In this situation, the traditional variance estimation technique based on ordinary least squares constantly exhibits a high bias even under sparsity assumption. One of the major reasons is the high spurious correlation between unobserved realized noise and several predictors. To alleviate this problem, a refitted cross-validation (RCV) method has been proposed in the literature. However, for a complicated model, the RCV exhibits a lower probability that the selected model includes the true model in case of finite samples. This phenomenon may easily result in a large bias of variance estimation. Thus, a model selection method based on the ranks of the frequency of occurrences in six votes from a blocked 3×2 cross-validation is proposed in this study. The proposed method has a considerably larger probability of including the true model in practice than the RCV method. The variance estimation obtained using the model selected by the proposed method also shows a lower bias and a smaller variance. Furthermore, theoretical analysis proves the asymptotic normality property of the proposed variance estimation. 相似文献

Critical discourse analysis (CDA) is employed to analyze discourses of knowledge and the knowledge society in the Sustainable Development Goals (SDGs). Discourse analysis is a collective name for a number of scientific methodologies for analyzing semiosis, namely how meaning is created and communicated though written, vocal or sign language. Employing a genealogical approach which locates discourses in the field of prior discourses, two prior discourses of the knowledge society are identified in the key document of the SDGs. The concepts knowledge and knowledge society are found to have a marginal position within the main policy document “Transforming our world,” adopted by the United Nations in September 2015. The techno‐scientific‐economic discourse is found to be dominant at the level of implementation and of goals, while there is some evidence of the pluralist‐participatory discourse at the level of vision and strategy. Analysis of some of the policy advice provided by international organizations and civil society indicates that more pluralist‐participatory discourses on knowledge were represented when the SDGs were being formulated. Developed countries and the corporate sector were very influential in determining the final text and were probably instrumental in excluding more transformational discourses and maintaining the status quo. 相似文献

广西大藤峡地区在明代以猺乱频繁而闻名。明中期,桂西土司狼兵进入当地平乱,明政府安插教化,形成了猺、獞、狼、民等族类共存的格局。清朝,隨着国家正统文化秩序确立,土著通过创建宗族等方式建构祖先的士大夫形象。现今该地区被称为猺、獞、狼者已踪影难觅,取而代之者是被认定为汉族的人群,大多族谱也称祖先来自广东。族群标签及族谱编撰的背后,呈现的是地方社会变迁与国家秩序建立的复杂历史过程。本文以大藤峡地区崇姜里人群的身份变化为个案来揭示此过程。 相似文献
