Preference rankings usually depend on the characteristics of both the individuals judging a set of objects and the objects being judged. This topic has been handled in the literature with log-linear representations of the generalized Bradley-Terry model and, recently, with distance-based tree models for rankings. A limitation of these approaches is that they only work with full rankings or with a pre-specified pattern governing the presence of ties, and/or they are based on quite strict distributional assumptions. To overcome these limitations, we propose a new prediction tree method for ranking data that is totally distribution-free. It combines Kemeny’s axiomatic approach to define a unique distance between rankings with the CART approach to find a stable prediction tree. Furthermore, our method is not limited by any particular design of the pattern of ties. The method is evaluated in an extensive full-factorial Monte Carlo study with a new simulation design.  相似文献

While the strength of the lifecourse/developmental (LCD) perspective in the examination of antisocial behavior has been clearly demonstrated, this work has given little attention to schools and education as salient influences. By contrast, there is much research using other theoretical frameworks to examine school-related risk factors of deviance. Given what we know about the importance of schooling and education on individual development and subsequent implications for behavior, we contend that academic influences should be more prevalent in LCD theories of deviance and that research using an LCD theoretical perspective should embrace non-LCD work examining school-related risk factors of antisocial behavior.  相似文献

The practice of the Western medicine often identifies the symptom with the disease itself, but a current of thought and medical practice considers it as the important message of an organic imbalance. In fact, in standard therapies symptoms are usually suppressed, thus interrupting a normal physiological process and risking severe reactions due to the organic imbalance. Dr. Hahnemann, the father of homeopathy, founded his diagnostic and therapeutic model on the interpretation of the symptoms and maintained that symptoms are an expression of altered physiology. The same concept is to be found in Dr. Reckeweg's “reactivity” and homotoxicology; he believed that diseases are the expression of the struggle of the body against toxins. Reckeweg's contribution was particularly important in considering the inflammation process as a biologic process through which the body restores its health. Also PNEI (psycho-neuro-endocrino-immunology) proposes a model where the symptom is interpreted as information and as the result of an imbalance. Several other medical approaches address particular attention to the meaning of symptoms. The Bach Flower Therapy, for instance, is guided exclusively by the negative moods, which can become the cause of functional and organic diseases; balance is restored thanks to superior harmonic energetic vibrations conveyed by the superior energy living in some flowers. This interpretation of the nature of symptoms is becoming a more and more relevant issue among both the specialistic and the general public.  相似文献

The main objective of this article is to address the impact of narrative practices in life celebration after the age of 80 and in the co-construction of a community-positive future. We share here an exploratory reflection about the narratives of a group of older women integrated in a community project. The Wednesday Tea Project (Chá das Quartas) has been ongoing for 4 years, and involves a group of old women experiencing high levels of loneliness and isolation in their small village in Portugal. The Wednesday Tea Project is based on positive psychology methodologies and consists of ritualized sessions that encourage participatory group dynamics. To describe how this project has highlighted the benefits of narrative practices, we utilized a series of scaffolding questions. Some of the most relevant outcomes of this project are: (a) the deconstruction of the dominant social discourse; (b) the publication of a book; (c) the reduction of loneliness feelings by re-membering significant figures; and (d) new levels of action both to women and the community as a consequence of a re-authoring process. Narrative practices seem to have contributed to the consolidation of all time dimensions, giving these women the opportunity to celebrate life after the age of 80, while also allowing the community to be part of and to benefit from the process. A reflection about the contributions of this article to a paradigm change toward positive aging is presented.  相似文献

In 2011, van Dijck and Fias described a positional SNARC (Spatial‐Numerical Association of Response Codes) effect: the SPoARC (Spatial‐Positional Association of Response Codes). To‐be‐remembered items (e.g., numbers, words) presented centrally on a screen seemed to acquire a left‐to‐right spatial dimension. If confirmed, this spatialization could be crucial for immediate memory theories. However, given the intricate links between visual and spatial dimensions, this effect could be due to the visual presentation (on a computer screen), which could have probed the left‐to‐right direction of reading/writing. To allow a generalization of this effect, we adapted van Dijck and Fias's (2011) task using an auditory version of Sternberg's paradigm. Lists of five consonants were auditorily presented at a rate of 3 s/item. A SPoARC effect was observed. The consequences are discussed first from an immediate memory perspective, putting forward the view that order could be coded through spatialization, and then in terms of similarities between SPoARC and SNARC.  相似文献

It has been proposed previously that extrinsic motivation may enable survivors of childhood medulloblastoma to significantly improve aspects of neurocognitive performance. In healthy populations, enhanced motivation has been shown to promote academic fluency, a domain likely more relevant to the educational outcomes of pediatric medulloblastoma survivors than academic skill development. The present study investigates the effect of enhanced extrinsic motivation on fluent (i.e., accurate and efficient) academic performance in pediatric medulloblastoma survivors. Participants were 36 children, ages 7–18, who had completed treatment for medulloblastoma. Participants completed a neuropsychological battery that included administration of equivalent tasks on Forms A and B of the Woodcock-Johnson III Tests of Achievement. Half were randomly assigned to an incentive condition prior to the administration of Form B. Provision of a performance-based incentive resulted in statistically significant improvement, but not normalization of function, in performance on measures of academic fluency. No demographic, treatment-related, academic, neuropsychological, or self-perception variables predicted response to incentive. Findings suggest that academic performance of survivors may significantly improve under highly motivating conditions. In addition to implications for educational services, this finding raises the novel possibility that decreased motivation represents an inherent neuropsychological deficit in this population and provides a rationale for further investigation of factors affecting individual differences in motivational processes. Further, by examining effort in a context where effort is not inherently suspect, present findings also significantly contribute to the debate regarding the effects of effort and motivation on neuropsychological performance.  相似文献

Understanding influence on and effects of retesting is important to the selection practitioner. This article examines retesting effects on a series of selection measures for mechanically related positions to extend research that has been conducted in more controlled environments. While validity was not significantly different on retesting, time between test attempts and score increase on Spatial Reasoning were positively related, indicating the possibility of learning effects. Lower score increases were found for highly g‐loaded measures, and individuals who showed an increase scored more highly on average on their first attempt. Men tended to increase their scores more than women. We close with a discussion of the practical implications of our findings and how to build on them with future research.  相似文献

The commentary by Maria Pia Roggero and Michele Minolli offers interesting points that enrich and clarify the discussion: the application of theoretical tenets to clinical practice and research, and different viewpoints on the concept of mismatching. We argue that miscommunication, misunderstanding, and loss of coordination cause mismatching exchanges and rupture the emotional connection between caregiver and infant as well as between analyst and patient (Tronick, 2007). We think that the process of mismatching and reparation is actually a developmental opportunity to dyadically expand the consciousness of infant and patient, as well as parent and therapist (Minolli, 2015).  相似文献
