Valerie Møller 《Journal of Happiness Studies》2001,2(1):33-53
Five years after South Africa's first democratic elections in 1994, life satisfaction and happiness still reflect societal divides sowed by apartheid social engineering. The paper reports the indicators: life satisfaction, happiness and expectations for the future, from national surveys conducted between 1983 and 1999 for the South African Quality-of-Life Trends Project. Post-election euphoria, which saw all South Africans happy and satisfied with life for a brief moment in 1994, raises the question where the new set-level of subjective well-being will eventually come to rest. In 1999, in spite of some gains in living conditions, the level of life satisfaction of blacks has not risen above the mid-point and happiness is only slightly above the mid-point. Meanwhile, whites, who have forfeited their political dominance, continue to score above the mid-point on happiness and life satisfaction. The paper draws on the literature, particularly on quality-of-life trends in reunified Germany and paradoxical trends in African-American life satisfaction when discussing the dynamics underlying South African subjective well-being. It is argued that coping mechanisms may play an important role in determining levels of subjective well-being in the complex situation of South Africa. 相似文献

对生命进化的本质问题作了新的哲学思考,提出进化的本质是物种在生存的驱动下生存效率的优化过程,是原始细胞自主性与环境选择的双向过程。同时提出推动物种进化的动力在于生存资源稀缺性与物种自私性之间的矛盾和多细胞物种效率优化过程中自身的局部利益与整体利益之间的矛盾。 相似文献

We consider a formal language whose logical syntax involves both modal and tense propositional operators, as well as sortal
quantifiers, sortal identities and (second order) quantifiers over sortals. We construct an intensional semantics for the
language and characterize a formal logical system which we prove to be sound and complete with respect to the semantics. Conceptualism
is the philosophical background of the semantic system. 相似文献

Our research examined the impact of contextual intergroup variables on the subjective well‐being of ethnic Russians in Estonia (N = 190) who have experienced major social changes with the demise of the Soviet Union. A mediational model was tested where aspects of intergroup relations (i.e., relative deprivation, status legitimization, and temporal comparisons) acted as mediators of the influence of cultural identity and representations of history on subjective well‐being. Preliminary analyses indicated polemical representations of history in which Estonian historical narratives are established around the struggle for independence, and Russian representations of history are consolidated around victory in World War II. Mediation analyses demonstrated that the importance of Russian history increased the perceptions of relative deprivation, status delegitimization, and the frequency of temporal comparisons, which negatively affected life satisfaction. At the same time, the importance of Estonian history led to positive perceptions of the intergroup situation and, in turn, to greater subjective well‐being. The effect of Russian identity on well‐being was mediated by delegitimizing beliefs, but not by relative deprivation and temporal comparisons. Estonian identity did not exert a significant effect on the proposed mediators. The research demonstrates the salience of the effects of contextual intergroup factors on subjective well‐being, and the article discusses implications for the study of intergroup relations and subjective well‐being. 相似文献

Absolute pitch (AP) is the ability to identify or produce notes without any
reference note. An ongoing debate exists regarding the benefits or disadvantages
of AP in processing music. One of the main issues in this context is whether the
categorical perception of pitch in AP possessors may interfere in processing
tasks requiring relative pitch (RP). Previous studies, focusing mainly on
melodic and interval perception, have obtained inconsistent results. The aim of
the present study was to examine the effect of AP and RP separately, using
isolated chords. Seventy-three musicians were categorized into four groups of
high and low AP and RP, and were tested on two tasks: identifying chord types
(Task 1), and identifying a single note within a chord (Task 2). A main effect
of RP on Task 1 and an interaction between AP and RP in reaction times were
found. On Task 2 main effects of AP and RP, and an interaction were found, with
highest performance in participants with both high AP and RP. Results suggest
that AP and RP should be regarded as two different abilities, and that AP may
slow down reaction times for tasks requiring global processing. 相似文献

A prominent example in the literature on relative ranking is the “better‐than‐average” effect: that people have a general tendency to view themselves in a positive light and think they are above average. The current paper evaluates whether such biases are specific to culture. In Experiment 1, Americans exhibited a larger better‐than‐average effect than Chinese. In Experiment 2, the study was designed to understand what drives this cultural difference. Estimates of relative standing for Americans relied more on perceptions of their own ability compared to those for Chinese participants. Relatively structured questions (experimental manipulation of the question frame) facilitate Americans making better judgments but not Chinese, supporting the hypothesis that relative‐ranking estimates are influenced by the degree to which other (vs. self) information is used cross‐culturally. 相似文献

This study proposes an integrated qualitative and quantitative assessment of expert opinions aiming at ranking a set of five shantytowns (favelas) located in the city of Rio de Janeiro. These communities are candidates for investments in an energy efficiency program implemented by the local electric utility company. The city, state, and federal governments want to eliminate domination of these areas by organized criminal gangs and present the city as a peaceful metropolis while hosting two big sports events: the soccer World Cup in 2014 and the Olympic Games in 2016. In recent years, some favelas were chosen to be prototypes for an ambitious project to reshape Rio de Janeiro. This involves first sending in special tactics police to drive drug gangs out, then installing the Pacifying Police Unit in the favela. Once security has been established, it is possible to improve general living conditions in these areas, including by providing public services such as health clinics, formal electricity connections and cable television. The core of the energy efficiency program was to convert informal customers to formal ones, because such communities were responsible for approximately 40% of the commercial losses (stolen energy) in the city. The model specification presented in this paper was set up with ten relevant criteria for decision making, identified through an in‐depth interview with the decision maker. The relative importance of the criteria and the performance of each favela regarding each criterion were measured by the Simos method. The preferences resulting from this method were translated into a nine‐point scale. The imprecision of subjective judgment was partially compensated by using a fuzzy analytical hierarchy process. Some criteria were ordinal, such as ‘Fair Relationship with the Community’ and ‘Complexity to Rebuild the Distribution Lines’, whereas other were cardinal, like ‘Percentage of Clients in Default’ and ‘Commercial Loss Due to Energy Theft’. At the end, the model was efficient in ranking the five favelas, therefore contributing to a rational and transparent approach for capital investment in social projects.

Previous studies on individual differences in intelligence and brain activation during cognitive processing focused on brain regions where activation increases with task demands (task-positive network, TPN). Our study additionally considers brain regions where activation decreases with task demands (task-negative network, TNN) and compares effects of intelligence on neural effort in the TPN and the TNN. In a sample of 52 healthy subjects, functional magnetic resonance imaging was used to determine changes in neural effort associated with the processing of a working memory task. The task comprised three conditions of increasing difficulty: (a) maintenance, (b) manipulation, and (c) updating of a four-letter memory set. Neural effort was defined as signal increase in the TPN and signal decrease in the TNN, respectively. In both functional networks, TPN and TNN, neural effort increased with task difficulty. However, intelligence, as assessed with Raven's Matrices, was differentially associated with neural effort in the TPN and TNN. In the TPN, we observed a positive association, while we observed a negative association in the TNN. In terms of neural efficiency (i.e., task performance in relation to neural effort expended on task processing), more intelligent subjects (as compared to less intelligent subjects) displayed lower neural efficiency in the TPN, while they displayed higher neural efficiency in the TNN. The results illustrate the importance of differentiating between TPN and TNN when interpreting correlations between intelligence and fMRI measures of brain activation. Importantly, this implies the risk of misinterpreting whole brain correlations when ignoring the functional differences between TPN and TNN. 相似文献
