中国现代思想中的知识论:朝向一种新的整体

在西方话语中占优势地位的自然主义知识论的主题乃是在很大程度上独立于理解主体的外部世界(或客观实在)。中国传统知识论可以被称作关系知识论,因为它们关涉的主题是关系。这不但适用于否定实体观念的整体主义知识论,而且还适用于许多倡导在理解主体与理解客体间作出严格区分的现代理论。在这一方面,对中西传统知识理论作一比较分析也许不失为一种解决关于人类理解的性质与对实在的认知的某些基本问题的有益方法。     

Propagation of Uncertainty in Risk Assessments: The Need to Distinguish Between Uncertainty Due to Lack of Knowledge and Uncertainty Due to Variability

In quantitative uncertainty analysis, it is essential to define rigorously the endpoint or target of the assessment. Two distinctly different approaches using Monte Carlo methods are discussed: (1) the end point is a fixed but unknown value (e.g., the maximally exposed individual, the average individual, or a specific individual) or (2) the end point is an unknown distribution of values (e.g., the variability of exposures among unspecified individuals in the population). In the first case, values are sampled at random from distributions representing various "degrees of belief" about the unknown "fixed" values of the parameters to produce a distribution of model results. The distribution of model results represents a subjective confidence statement about the true but unknown assessment end point. The important input parameters are those that contribute most to the spread in the distribution of the model results. In the second case, Monte Carlo calculations are performed in two dimensions producing numerous alternative representations of the true but unknown distribution. These alternative distributions permit subject confidence statements to be made from two perspectives: (1) for the individual exposure occurring at a specified fractile of the distribution or (2) for the fractile of the distribution associated with a specified level of individual exposure. The relative importance of input parameters will depend on the fractile or exposure level of interest. The quantification of uncertainty for the simulation of a true but unknown distribution of values represents the state-of-the-art in assessment modeling.     

SYMBOLIC REALITY BITES: WOMEN AND RACIAL/ETHNIC MINORITIES IN MODERN FILM

Criticisms of mass media productions often include a discussion of how women and minorities are systematically excluded and/or relegated to minor roles, or roles that match traditional stereotypes. These types of portrayals are important factors in the social construction of reality among the general public, and therefore may perpetuate racism and sexism on a larger scale. Using a content analysis of fifty popular films in 1996 the present study explores the demographic composition of the leading actresses and actors. The goal is to gauge the strength of female and minority presence and to provide an assessment of character representations through an analysis of labor force participation, sex-roles of occupation, prestige of occupation, and gender. Findings indicate that although both women and minorities have made some advancement in their film portrayals, compared to earlier studies, they still are under-represented in leading roles in Hollywood, and their portrayals are often consistent with traditional stereotypes.     

Resilience in parenting among young mothers: Family and ecological risks and opportunities

The present study used a person-centered approach to examine resilience in parenting among a sample of young mothers (under age 21 at childbirth). Resilient functioning as a parent was defined as the lack of perpetration of child maltreatment (substantiated reports of child abuse and neglect) in the context of risk. Risk factors were assessed at multiple levels, including family (e.g., negative childhood histories in family of origin) and ecological (e.g., neighborhood poverty, mother's financial stress) levels. Analyses revealed a group of mothers who demonstrated resilience in parenting despite a context of substantial risks from their childhood histories (e.g., negative family relationships) and current ecologies (e.g., economic and neighborhood conditions). Mothers in the resilient group were less likely to a) live with their families of origin, and b) to rely on their own mothers as sources of emotional or caregiving support. Data also indicated that young mothers' resilient functioning as parents was associated with higher rates of depressive symptoms among these mothers, perhaps suggesting a “cost” or limit to resilient parenting functioning in young mothers. Results are discussed in a resilience framework.     

Information Technology Risks as Seen by the Public

Risks related to information technology (IT) are becoming a focus of concern in current risk debates. The use of IT is rapidly spreading in the population, as is access to computers in general. The present article reviews the literature on IT use (especially electronic mail and various Internet applications) and the related risks. In addition, the results from a survey about IT use and risk perception, given to a random sample of the Swedish population, are reported. In general, participants were quite positive to IT and were, to some extent, aware of the related risks. However, risks of IT were mostly seen as pertinent to other people, a finding in contrast with other results on perceived technology hazards. The attitude toward the use of IT was strongly related to general attitude toward computers, and less clearly to risk perception. Only a small percentage of the respondents reported having had negative experiences with IT hazards such as Internet addiction, depression, and social isolation. When extrapolated to the general population, however, these small percentages amount to large groups in the population that have been negatively affected by IT use.     

Coaching im Dilemma von Psychopolitik und Selbstbefreiung

In this article the concept of “psychopolitics” will be applied on coaching. It describes a form of government and power in neoliberalism. The basic principle relies on influencing a person’s psyche to the point of motivating them to self-optimize in the interest of economic logic of utilization. The philosophical and sociological literature on the topic criticizes and questions coaching as it is seen as an instrument of psychopolitics. The article describes the concept of psychopolitics. It discusses to what extent coaching is either used as a means of self-optimizing, or self-liberation. Questions and courses of action will be clarified with the help of a case example.     

Analysis of environmental flow requirements for macroinvertebrates in a creek affected by urban drainage (Prague metropolitan area,Czech Republic)

The habitat suitability index and environmental flow requirements were assessed for ten species of macroinvertebrates in a 2 km length section of the urban Boti? creek (average flow 0.4 m³ s^?1) in Prague. Boti? creek has been affected by two combined sewer overflows (CSO). Spring, summer and fall seasonal environmental flow requirements were identified using the Physical HABitat SIMulation System (PHABSIM) approach for the whole macroinvertebrate community: Spring – optimal flow 0.32–0.38 m³ s^?1, minimal flow 0.20–0.21 m³ s^?1 and maximal acceptable flow 0.91–0.93 m³ s^?1; Summer - optimal flow 0.42–0.45 m³ s^?1, minimal flow 0.19–0.21 m³ s^?1 and maximal acceptable flow 0.95–1.00 m³ s^?1; Fall - optimal flow 0.38–0.48 m³ s^?1, minimal flow 0.22–0.23 m³ s^?1 and maximal acceptable flow 0.95–0.98 m³ s^?1. The seasonal variability of environmental flow for all three categories is approximately 10%. Environmental flow requirements of the studied species and their life stages vary with depth, velocity and bottom substratum. Due to inflow from the CSOs, the optimal and maximal acceptable flow are not maintained and the maximal flow is exceeded by more than twice its value. Although the Instream Flow Incremental Methodology (IFIM) was primarily designed for large impounded rivers, the study proved its applicability in small streams affected by urbanization and urban drainage.     

Communicative Openness About Adoption and Interest in Contact in a Sample of Domestic and Intercountry Adolescent Adoptees

Adolescent intercountry (n = 122) and domestic (n = 40) adoptees and their adoptive parents were asked about their views on communicative openness. The adoptees were also asked for their thoughts on birth parents and contact. A modest association between communicative openness and feelings about adoptive status and self-esteem was found. Girls were more interested in many aspects of their adoptions than boys. Compared with the situation at 11 years of age, there was greater parent-child agreement on whether the child had difficulties talking about adoption. Nevertheless, at age 15, children were still nearly twice as likely to report difficulties talking about adoption issues than their adoptive parents realized. At the age of 15, the majority of the adoptees expressed a desire for contact with birth relatives, but this was a reduction from the numbers at age 11. They also reported finding it easier to talk about adoption issues than they did at the age of 11. The implications for policy and practice are discussed.     

Influence of Parenting Behavior on Psychosocial Adjustment in Early Adolescence: Mediated by Anger Regulation and Moderated by Gender

Emotion regulation (ER)—one of the most important developmental tasks in early adolescence—has been proposed to mediate the relation between parenting and adolescents’ psychosocial adjustment. The aim of this study was to examine the influence of parental psychological control and autonomy support on adolescents’ problem and prosocial behavior (Strengths and Difficulties Questionnaire), as well as to examine the mediating role of adolescents’ anger regulation and the moderating effect of gender. We collected three‐year longitudinal questionnaire data from N = 923 parents and their (at first assessment) 9‐ to 13‐year‐old children. Path‐analysis results mainly support the mediating role of adolescents’ adaptive and maladaptive anger regulation and suggest parental autonomy support to be beneficial for regulatory abilities and psychosocial adjustment, whereas the opposite was found for psychological control. Gender differences were found for parent report data, but not for adolescent report data. Practical and theoretical implications are discussed.
