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

The present study examined relations between choice preference and reaction time to emotionally valenced words, dysphoric symptoms (BDI), and dysfunctional attitudes (DAS) in clinically depressed (CD; n= 61), previously depressed (PD; n= 42), and never depressed controls (ND; n= 46). The results showed: (1) NDs and PDs exhibited a choice preference for the relatively more positive words and differed significantly from CDs; (2) PDs and CDs exhibited longer reaction time and differed significantly from NDs; and (3) BDI and DAS were positively associated with reaction time to positively valenced words, whereas no associations were found for reaction time to negatively valenced words. The increased reaction time, in PDs and CDs, is discussed as a possible vulnerability factor to depression, which may be related to decreased approach motivation. 相似文献
Using consensual qualitative research, the authors examined the treatment planning process of experienced counselors (N = 9). The data analysis resulted in 4 domains: assessment steps, clinical impressions, treatment factors, and treatment strategies. These domains describe the process used by experienced counselors in making clinical decisions and offer insight into the nature of clinical expertise and the need for further research on treatment planning. 相似文献
The author describes his personal and professional journey in relation to the subject of the AJA 40th anniversary conference, ‘Who is my Jung?’ The first part of the paper covers his early life and his attempt to bring together two opposing parts within him: valuation of a scientific approach, and an interest in the inner world, dreams and the paranormal. Discussion of his professional life follows, including his relationship with Gerhard Adler, past problems and splits within the Jungian community and the author's attempts to heal these. The value of both remembering and forgetting is questioned. This leads onto ideas that bring value and meaning to his work and life, and which bridge the inner divisions he felt in his early life: notably Jung's focus on applying scientific theory to the mystery of the psyche, his relational attitude (exemplified by the dialectical process and his interest in countertransference) and his theory of synchronicity. Recent discussion in Jungian writing has questioned the nature of synchronistic experiences and explored how they may emerge naturally from complex systems. The paper ends the author's continuing journey with two personal vignettes describing how meaning may emerge from the unconscious. 相似文献
Objective. A randomised controlled trial (RCT) was conducted to evaluate a three-hour face-to-face physical activity (PA) intervention in community-dwelling older German adults with four groups: The intervention group (IG) received behaviour change techniques (BCTs) based on the health action process approach plus a views-on-ageing component to increase PA. The second intervention group ‘planning’ (IGpl) contained the same BCTs, only substituted the views-on-ageing component against an additional planning task. An active control group received the same BCTs, however, targeting volunteering instead of PA. A passive control group (PCG) received no intervention.
Design. The RCT comprised 5 time-points over 14 months in N = 310 participants aged 64+.
Main outcome measures. Self-reported as well as accelerometer-assessed PA.
Results. Neither PA measure increased in the IG as compared to the other groups at any point in time. Bayes analyses supported these null-effects.
Conclusion. A possible explanation for this null-finding in line with a recent meta-analysis is that some self-regulatory BCTs may be ineffective or even negatively associated with PA in interventions for older adults as they are assumed to be less acceptable for older adults. This interpretation was supported by observed reluctance to participate in self-regulatory BCTs in the current study. 相似文献
ObjectivesThe aim of the current study was twofold. First, to explore whether there were different trajectories of exhaustion among high-performance coaches over the course of a competitive season. Then, to investigate whether workload-related variables and motivational regulations were associated with exhaustion class membership.Methods and design299 high-performance coaches responded to an online survey at the start, middle, and end of a competitive season, assessing exhaustion, workload, work home interference (WHI), recovery, and motivational regulations. Latent class growth analyses were used to identify different trajectories of perceived exhaustion. Further, multinomial logistic regression examined class associations for workload-related variables and motivational regulations at the start and at the end of competitive season.ResultsFour different trajectories of perceived exhaustion among coaches were identified, termed respectively “High” (10%), “Increase” (15%), “Decrease” (4%) and “Low” (71%). Higher levels of workload and WHI were associated to classes with higher levels of exhaustion. Higher levels of recovery, and intrinsic and identified regulations were associated to classes with lower levels of exhaustion. Adaptive and maladaptive profiles were identified.ConclusionsDifferent trajectories of exhaustion among high-performance coaches over the course of a competitive season were found. A maladaptive profile was associated with higher perceived workload and WHI, as well as lower levels of recovery, intrinsic and identified regulations, when compared to the adaptive profile. 相似文献
This paper outlines a view of early relational trauma as underlying borderline states of mind, and argues that Knox's 1999 paper on internal working models and the complex provides a basis for understanding such states of mind. The author argues that in addition to internal working models, the complex also embodies and contains primitive defences of the core self. He outlines how these apply on the objective, subjective, transference and archetypal levels, and in direct and reversed forms and applies this to the account of Fordham's analysis of his patient ‘K’, which ended in impasse. The paper explores the dynamic that emerged in that analysis and suggests that it could be helpfully accounted for in terms of the co‐construction and re‐construction of early relational trauma in the analytic relationship. 相似文献
