The fuzzy perspective in statistical analysis is first illustrated with reference to the “Informational Paradigm” allowing
us to deal with different types of uncertainties related to the various informational ingredients (data, model, assumptions).
The fuzzy empirical data are then introduced, referring to J LR fuzzy variables as observed on I observation units. Each observation is characterized by its center and its left and right spreads (LR1 fuzzy number) or by its left and right “centers” and its left and right spreads (LR2 fuzzy number). Two types of component models for LR1 and LR2 fuzzy data are proposed. The estimation of the parameters of these models is based on a Least Squares approach, exploiting
an appropriately introduced distance measure for fuzzy data. A simulation study is carried out in order to assess the efficacy
of the suggested models as compared with traditional Principal Component Analysis on the centers and with existing methods
for fuzzy and interval valued data. An application to real fuzzy data is finally performed.
We would like to express our gratitude to the Editor, the Associate Editor, and the Referees whose comments and suggestions
improved significantly the quality of the paper. 相似文献

This study investigated whether conscious and preconscious memory features contribute to discrimination between depressive
and somatoform disorders. Thirty-one participants fulfilling the diagnostic criteria for a somatoform disorder and 28 participants
fulfilling the criteria for depression were examined within the framework of the process–dissociation paradigm using neutral,
health-threatening, and general threatening words in a lexical decision task. Parameters of conscious memory, preconscious
memory, and chance were used to compare memory features of both the groups. There was an inverse relationship between conscious
and preconscious memory effects for health-threatening stimuli in the group of patients with somatoform disorders but not
in the group of depressive patients. Patients with somatoform disorders showed a significantly lower level of conscious memory
for health-threatening stimuli than depressive participants. Compared to depressive patients, a more dynamic relationship
between decreased conscious and increased preconscious memory for health-related stimuli seems to be characteristic for patients
with somatoform disorders. 相似文献

In seeking to answer the question “How does that which is other become evil?” the author provides a discussion of four entwined aspects of the issue at stake; (1) difficulty in achieving clarity on the grammar of evil; (2) genocide as a striking illustration of otherness becoming evil; (3) the challenge of postnationalism as a resource for dealing with otherness in the socio-political arena; and (4) the ethico-religious dimension as it relates to the wider problem of evil. 相似文献

This study examined the influence of gender and Internet use on the sexual behavior orientation of young adults in Nigeria. Using an ex-post-facto design, data were collected from a total of 231 participants. Results of the hierarchical regression model provided support for the influence of gender and Internet use on sexual behavior orientation among young Nigerians. Further, results also revealed an interaction effect; as the use of the Internet increased, male participants reported a greater extent of risky sexual behavior orientation than their female counterparts. The findings were explained in the context of the theoretical foundations of the study, while practical implications for combating youths' risky sexual behavior orientation were highlighted. 相似文献

In this paper I look at attempts to develop forms of consequentialism which do not have a feature considered problematic in Direct Consequentialist theories (that is, those consequentialist theories that apply the criterion of rightness directly in the evaluation of any set of options). The problematic feature in question (which I refer to as ‘evaluative conflict’) is the possibility that, for example, a right motive might lead an agent to perform a wrong act. Theories aiming to avoid this phenomenon must argue that causal relationship entails motives and acts (for example) having the same moral status. I argue that attempts to ensure such ‘evaluative consistency’ are themselves deeply problematic, and that we must therefore accept evaluative conflict. 相似文献

Research interest on the commitment–performance link persists, and recent efforts have focused on investigating the contextual factors due to the mixed outcome of the empirical studies. However, very limited study has examined the influence of economic factors including economic volatility, and none in the dual setting of the organization and the union. This study investigated the contextual influence of perceived inflation—an economic volatility construct—on commitment and extra-role performance. Exchange theory, with support from psychological contract and equity theories, was used to postulate two parallel, but competing models of the organization and the union. Using a sample of 247 unionized employees in southern U.S.A., the study tested the moderating effect of perceived inflation on the relation between commitment and citizenship intent. The results revealed three-way interactive effects in both models, in a dual commitment setting. Thus, the economic volatility construct acts as a situational constraint on the link between the attitudinal-based commitments and citizenship intent, but in the contexts of obligation and cost-based commitments to the organization and the union respectively. The implications of these mitigated effects are discussed. 相似文献

Kruger and Dunning (1999) described a metacognitive bias in which insight into performance is linked to competence: poorer performers are less aware of their mistakes than better performers. Competence-based insight has been argued to apply generally across task domains, including a recent report investigating social cognition using a variety of face-matching tasks. Problematically, serious statistical and methodological criticisms have been directed against the traditional method of analysis used by researchers in this field. Here, we further illustrate these issues and investigate new sources of insight within unfamiliar face matching. Over two experiments (total N = 1077), where Experiment 2 was a preregistered replication of the key findings from Experiment 1, we found that insight into performance was multi-faceted. Participants demonstrated insight which was not based on competence, in the form of accurate updating of estimated performance. We also found evidence of insight which was based on competence: the difference in confidence on correct versus incorrect trials increased with competence. By providing ways that we can move beyond problematic, traditional approaches, we have begun to reveal a more realistic story regarding the nature of insight into face perception. 相似文献
