An RKHS framework for functional data analysis

Linear combinations of random variables play a crucial role in multivariate analysis. Two extension of this concept are considered for functional data and shown to coincide using the Loève–Parzen reproducing kernel Hilbert space representation of a stochastic process. This theory is then used to provide an extension of the multivariate concept of canonical correlation. A solution to the regression problem of best linear unbiased prediction is obtained from this abstract canonical correlation formulation. The classical identities of Lawley and Rao that lead to canonical factor analysis are also generalized to the functional data setting. Finally, the relationship between Fisher's linear discriminant analysis and canonical correlation analysis for random vectors is extended to include situations with function-valued random elements. This allows for classification using the canonical Y scores and related distance measures.     

Application of the Rural Development Index to Analysis of Rural Regions in Poland and Slovakia

The main purpose of this research was to construct a multi-dimensional (composite) index measuring the overall level of rural development and quality of life in individual rural regions of a given EU country. In the Rural Development Index (RDI) the rural development domains are represented by hundreds of partial socio-economic, environmental, infrastructural and administrative indicators/variables at NUTS-4 level (e.g. 991 variables/indicators describing various aspects of rural development in Poland; 340 variables/indicators in Slovakia). The weights of economic, social and environmental domains entering the RDI index are derived empirically from the econometrically estimated intra- and inter-regional migration function after selecting the “best” model from various alternative model specifications (e.g. panel estimate logistic regression nested error structure model, spatial effect models, etc.). The RDI is empirically applied to analysis of the main determinants of rural/regional development in individual rural areas in years 2002–2005 in Poland and Slovakia at NUTS-4 level. Due to its comprehensiveness the RDI Index is suitable both to analysis of the overall level of development of rural areas and to an evaluation of the impacts (impact indicator) of RD and structural programmes at regional levels (NUTS 2–5).     

肿瘤坏死因子TNFa-308 G〉A基因多态性与迟发性阿尔茨海默病之间的关联研究

目的迟发性阿尔茨海默病（LOAD）是老年痴呆中最常见的一种,它是一种病因复杂、由遗传因素和环境等其他因素共同作用引起的老年期疾病。服用非甾类抗炎类药物能延缓或防止其发病,说明炎症反应可能参与病理,肿瘤坏死因子（TNF）是炎症反应中主要的细胞因子。方法采用病例对照研究设计,通过聚合酶链反应（PCR）和限制性片段长度多态性（RFLP）的方法,分析中国南方人群81例病例和158例正常对照组中TNFa-308和载脂蛋白E（ApoE）等位基因和基因型频率的差异。结果TNFa-308等位基因和基因型在病例对照中的分布无统计学差异;在LOAD病例组和正常对照组中,ApoEe4等位基因出现的频率分别为16．3％,7．9％,等位基因频率有显著差异（P=0．019）;与非84携带者相比,ApoEe4等位基因携带者发生AD的风险增大[OR（95％CI）=2．304（1．182～4．489）,P=0．015]。结论TNFa-308（rs1800629）可能与中国南方人阿尔茨海默病患病风险无关,ApoE甜等位基因可能是LOAD的遗传危险因子。

生态文明制度与文化的通约与融合

生态文明制度与文化因其相互影响、相生相长而存在哲学上的通约关系:文化是生态文明制度的内在支撑,影响生态文明制度的起源、演变及实效的发挥;生态文明制度是文化的外在表现形式,确认并引导文化观念、体现并衡平多样文化冲突.生态文明制度实效的发挥需要其与文化相融合,而通约性为两者的融合提供了前提.对生态文明制度与文化通约性的剖析有助于我们寻求生态文明制度与文化融合的路径,从而提高当前生态文明制度的文化契合性,促使其实效的发挥.     

Resilience and Decision‐Making Strategies as Predictors of Career Decision Difficulties

The purpose of this study was to examine resilience and decision‐making strategies as predictors of difficulties experienced during the career decision‐making process. College students (N = 364) responded to measures of resilience, career decision‐making strategies, and career decision difficulties. Results indicated that resilience and decision‐making strategies accounted for 46% of the variance in career decision difficulties. Resilience had a greater influence on problems encountered during decision making than on problems encountered at the outset of the process. Different decision‐making strategies appeared to be related to difficulties encountered at different stages of the decision‐making process. For example, aspiration for an ideal occupation was positively associated only with lack of readiness. Procrastination was the only strategy related to all three decision difficulties: lack of readiness, lack of information, and inconsistent information. The results indicated the importance of decreasing procrastination at all stages of decision making and the need to promote resilience to deal with decision difficulties.     

基于Copula模型的棉花收入保险费率测算研究

推行棉花收入保险有助于维护我国棉花产业的稳定发展.本文以新疆棉花为研究对象,设定棉花期货市场为有效市场,采用棉花单产及11月棉花期货合约价格,测算了棉花单位面积产量风险及价格风险,运用ClaytonCopula模型模拟了两变量的联合风险分布,测算了4种不同保障收入及其不同保障水平下的收入保险费率.研究发现:模拟的每亩棉花期望收入具有合理性,在棉花总成本75％的保障水平以下试行收入保险具有可行性,测算结果具有一定的实践指导价值.     

Queer Blindfolding: A Case Study on Difference “Blindness” Toward Persons Who Identify as Lesbian,Gay, Bisexual,and Transgender

The purpose of this article is to introduce and explore the narrative strategy of queer blindfolding. Utilizing psycho-discursive qualitative methodology, the authors will draw from a case study to demonstrate how some beneficent, well-intended persons who identify as heterosexual adopt the narrative strategy of queer blindfolding as they negotiate the discourse of heteronormativity. We will map this narrative strategy, compare and contrast it to racial colorblindness, and unpack the accompanying intra-psychic conflict and defense mechanisms that are utilized by the participant in the case study. We will also demonstrate how this discursive strategy positions participants within systemic heterosexism.     

Contingency,conflict, crisis: Strategy selection of religious public relations professionals

A national survey among religious public relations practitioners working for mainstream Protestant Christian churches was undertaken to examine strategic options in a conflict or crisis. Religious public relations professionals tend to employ collaborating, contending or compromising in a conflict with a given public, while they are likely to use concession or corrective action in a crisis. Internal contingent factors are mostly associated with accommodating, avoiding, concession or corrective action strategies, while contending is most often correlated with external contingent factors.
