对马克思主义理论整体性问题研究的反思及其现实意义

整体性是马克思主义理论的重要特性,整体性问题是研究马克思主义的一个基本问题,也是当前我国学者研究马克思主义的一个热点问题。我国理论界围绕此问题进行了深入而系统的研究,取得了丰硕成果,但也存在一些问题,对这些问题的反思,有益于进一步实现马克思主义整体发展和创新的前瞻性使命。     

On the α-risks for shewhart control charts

The performance of the usual Shewhart control charts for monitoring process means and variation can be greatly affected by nonnormal data or subgroups that are correlated. Define the α_k-risk for a Shewhart chart to be the probability that at least one “out-of-control” subgroup occurs in k subgroups when the control limits are calculated from the k subgroups. Simulation results show that the α_k-risks can be quite large even for a process with normally distributed, independent subgroups. When the data are nonnormal, it is shown that the α_k-risk increases dramatically. A method is also developed for simulating an “in-control” process with correlated subgroups from an autoregressive model. Simulations with this model indicate marked changes in the α_k-risks for the Shewhart charts utilizing this type of correlated process data. Therefore, in practice a process should be investigated thoroughly regarding whether or not it is generating normal, independent data before out-of-control points on the control charts are interpreted to be due to some real assignable cause.     

Control Balance Theory and Violence: An Examination of Contingencies

Abstract

Control balance theory has been previously tested using measures of contingencies. This article builds upon these studies by using data collected from 460 undergraduate students to examine the role of constraints and sensation-seeking in the control balancing process. The findings provide partial support for control balance theory (i.e., that the control deficit and the control surplus both have significant links to predation). Examining the contingency effects showed that the influence of the control deficits and surpluses on deviance was conditioned by contingencies (i.e., high levels of sensation-seeking and low levels of constraint). The findings from this study suggest the need for further exploration of control balance theory, with the focus to shift to Tittle's 2004 revision of the theory.     

Graphical and Numerical Methods for Detecting Influential Observations in Complex Bingham Data

We describe methods to detect influential observations in a sample of pre-shapes when the underlying distribution is assumed to be complex Bingham. One of these methods is based on Cook's distance, which is derived from the likelihood of the complex Bingham distribution. Other method is related to the tangent space, which is based on the local influence for the multivariate normal distribution. A method to detect outliers is also explained. The application of the methods is illustrated in both a real dataset and a simulated sample.     

Subjective priors for the dirichlet process

This paper reviews difficulties with the interpretation and use of the prior parameter u required in the Dirichlet approach to nonpararnetric Bayesian statistics. Two subjective prior distributions are introduced and studied. These priors are obtained computationally by requiring that the experimenter specify certain constraints.     

Access to Water in the Slums of Sub‐Saharan Africa

This article reviews the changing perspectives for improving access to water in the slums of developing countries, especially in sub‐Saharan Africa. While much of the literature continues to maintain an aversion to state‐led urban development policies, there is now increasing emphasis on the importance of informal, small‐scale providers and communitarian initiatives, following the many failures of privatisation. The article argues that market‐oriented solutions are inappropriate for sub‐Saharan African countries where over two‐thirds of the urban population live in squatter settlements with multidimensional challenges.     

Inequality and the Self: Exploring Connections from an Interactionist Perspective

Symbolic interactionism provides a major contribution to understanding inequality by illuminating the various manifestations and contexts of inequality at the micro, everyday level of social life. Drawing on a spectrum of symbolic interactionist theory and research, we examine the range of symbolic and interactional manifestations of social inequality, the consequences of being the object of patterned interactional affronts, and the strategies people use to negotiate interactional stigmatization in everyday life. We argue that symbolic interaction's unique contribution to understanding inequality results from two of the perspective's central features. First, symbolic interactionism emphasizes the necessity of investigating social life in situated social interaction. Second, it highlights social actors' capacities to interpret and construct lines of action rather than respond directly to the stimuli they encounter. Symbolic interactionist research and theory thus contribute to a more complex understanding of social stratification than that provided by perspectives focused exclusively on macroscopic structural factors.     

Adaptable Careers: Maximizing Less and Exploring More

Today, young adults are expected to decide between educational, vocational, and job options and to make the best choice possible. Career literatures emphasize the importance of young adults' career decision making but also acknowledge the problems related to making these decisions. The authors argue that career counselors could support clients' intuitive processing of career information and help their clients to develop a positive and flexible view of the self and the environment while diminishing concerns about accountability for and irreversibility of career decisions. The authors argue that career adaptability rather than decision making should become the focal concept of career theory and practice.
