Ideal-points are widely used to model choices when preferences are single-peaked. Ideal-point choice models have been typically estimated at the individual-level, or have been based on the assumption that ideal-points are normally distributed over the population of choice makers. We propose two probabilistic ideal-point choice models for the external analysis of preferences that allow for more flexible multimodal distributions of ideal-points, thus acknowledging the existence of subpopulations with distinct preferences. The first model extends the ideal-point probit model for heterogeneous preferences to accommodate a mixture of multivariate normal distributions of ideal-points. The second model assumes that ideal-points are uniformly distributed within finite ranges of the attribute space, leading to a more simplistic formulation and a more flexible distribution. The two models are applied to simulated and actual choice data, and compared to the ideal-point probit model.This research was funded by the Dean's Fund for Faculty Research of the Owen Graduate School of Management, Vanderbilt University. 相似文献

Abstract : Ted Peters' framework for ecumenic engagement provides elements that will advance such an encounter with Islam. Applying several of Peters' terms to interreligious relationships, Walter Wagner looks at various meetings between Muhammad and Christians contemporary to him. He cites the contacts between Muhammad and the first Muslim communities with Christians (610–632 AD) as both negative and positive paradigms for subsequent relationships. Wagner then points to Surah 1 as the key Quranic text for understanding Islam in relationship to Christianity. Reflecting on past efforts at dialogue and predicting what will be important future issues, Wagner stresses the intense religious nature of Islamic political‐social expectations and projects three factors for future ecumenic encounters between Islam and Christianity. 相似文献

The present study examines the structure of organizational citizenship behavior (OCB) and its relation to organizational commitment in Nepal. Four-hundred and fifty employees of five Nepalese organizations filled out standardized questionnaires. Exploratory and confirmatory factor analyses revealed two factors of OCB, altruism and compliance, replicating Western models of extra-role behavior. Structural equation analysis showed a positive relation between affective and normative commitment on the one hand and both citizenship factors on the other. Continuance commitment was negatively related to compliance and unrelated to altruism. The findings thus confirmed the structure and usefulness of the concepts in an under-researched geographical area. Findings of the research are discussed within the Nepalese sociocultural context. 相似文献

The place of impulsiveness in multidimensional personality frameworks is still unclear. In particular, no consensus has yet been reached with regard to the relation of impulsiveness to Neuroticism and Extraversion. We aim to contribute to a clearer understanding of these relationships by accounting for the multidimensional structure of impulsiveness. In three independent studies, we related the subscales of the Barratt Impulsiveness Scale (BIS) to the Big Five factors of personality. Study 1 investigated the associations between the BIS subscales and the Big Five factors as measured by the NEO Five‐Factor Inventory (NEO‐FFI) in a student sample (N = 113). Selective positive correlations emerged between motor impulsiveness and Extraversion and between attentional impulsiveness and Neuroticism. This pattern of results was replicated in Study 2 (N = 132) using a 10‐item short version of the Big Five Inventory. In Study 3, we analyzed BIS and NEO‐FFI data obtained from a sample of patients with pathological buying (N = 68). In these patients, the relationship between motor impulsiveness and Extraversion was significantly weakened when compared to the non‐clinical samples. At the same time, the relationship between attentional impulsiveness and Neuroticism was substantially stronger in the clinical sample. Our studies highlight the utility of the BIS subscales for clarifying the relationship between impulsiveness and the Big Five personality factors. We conclude that impulsiveness might occupy multiple places in multidimensional personality frameworks, which need to be specified to improve the interpretability of impulsiveness scales. 相似文献

Comparing Brief Experimental Analysis and Teacher Judgment for Selecting Early Reading Interventions
Dana L. Wagner Melissa Coolong-Chaffin Aaron R. Deris 《Journal of Behavioral Education》2017,26(4):348-370
The purpose of this study was to examine the use of brief experimental analysis (BEA) to identify early reading interventions for students in the primary grades and to compare teachers’ judgments about their students’ early reading intervention needs to BEA results. In addition, the research was conducted to explore how teachers make decisions regarding early reading intervention selection and evaluation. Three teachers and three elementary students (two kindergarten and one second grade) participated in the study. A BEA using a multielement design with mini-reversals was used to test the effects of four different interventions. Each teacher selected an intervention that she judged to be the most promising for her student. An extended analysis using an alternating treatments design compared the relative effects of the BEA-identified intervention and the teacher-identified intervention across time. The teachers were interviewed before and after selecting and implementing the interventions. The extended analysis results showed that the BEA-identified intervention was more effective than the teacher-identified intervention for all participants. Initial and final interview findings revealed that the teachers reported using data to make intervention decisions, but with limited specificity and in some cases, misjudgments. The results are discussed in regard to limitations and future research. 相似文献

We investigated a total of 4997 postings on an extreme right‐wing Internet discussion board with regard to the groups and themes mentioned. The most frequently mentioned target groups were Africans, Jews, Muslims, Poles, and Turks; the most prominent themes and contexts were conspiracy, criminality, exploitation, threats to German identity, infiltration, mind control and harassment, procreation, rape, and sex. We analysed in detail postings about Africans/Blacks and Jews, that is target groups that were the most clearly connected to particular themes. The analysis reveals that extreme right‐wing discourse essentializes the target groups of Jews and Africans/Blacks and ascribes them immutable group‐specific attributes that effectively make them ‘natural kinds’. The group of Jews appears as a kind of their own with super‐human powers and influence. Africans and Blacks are despised, firstly because their essential characteristics prohibit them to be categorically mixed with Germans (i.e. to become German by nationality) due to their incompatible essence, and secondly when they procreate with Whites. Such procreation produces ‘bastards’ that are met with disgust. We argue that essentialist thinking about social and ethnic groups explains a good part of their rejection by right‐wing followers.

Philosophers and social scientists have recently turned to Lewis sender–receiver games to provide an account of how lexical
terms can acquire meaning through an evolutionary process. However, the evolution of meaning is contingent on both the particular
sender–receiver game played and the choice of evolutionary dynamic. In this paper I explore some differences between models
that presume an infinitely large and randomly mixed population and models in which a finite number of agents communicate with
their neighbors in a social network. My results show that communication with neighbors is more conducive to the evolution
of meaning than communication with strangers. Additionally, I show that the behavior of the system is highly dependent on
the topological structure of the social network. I argue that a specific class of networks—small world graphs—is especially
conducive to the evolution of meaning. This is because small world graphs have a short characteristic path length while still
maintaining a high degree of correlation between neighbors. Since many actual social networks, such as friendship networks
and nervous systems, are conjectured to be small world structures, these results indicate that these networks are quite hospitable
to the efficient evolution of meaning. 相似文献

A simple rule of probability revision ensures that the final result ofa sequence of probability revisions is undisturbed by an alterationin the temporal order of the learning prompting those revisions.This Uniformity Rule dictates that identical learning be reflectedin identical ratios of certain new-to-old odds, and is grounded in the oldBayesian idea that such ratios represent what is learned from new experiencealone, with prior probabilities factored out. The main theorem of this paperincludes as special cases (i) Field's theorem on commuting probability-kinematical revisions and (ii) the equivalence of two strategiesfor generalizing Jeffrey's solution to the old evidence problem tothe case of uncertain old evidence and probabilistic new explanation. 相似文献

The Bureau of Justice Statistics estimates that approximately 1 in every 50 youth in the U.S. had a parent in State or Federal prison in 1999. Studies of children of incarcerated parents suggest that these youth are at risk for experiencing emotional and behavioral problems. Using a sample of 258 adolescents receiving routine mental health services, this study explored: (1) differences in demographic characteristics, lifetime exposure to risk factors, recent stressful life experiences, and clinical profiles of adolescents with and without a history of parental incarceration; and (2) the effect of parental incarceration relative to other risk factors on levels of emotional and behavioral problems and treatment outcomes. Nearly half (43%) of the youth studied had experienced the incarceration of one or both parents. Youth who experienced parental incarceration had been exposed to significantly more risk factors during their lifetimes including parental substance abuse, extreme poverty, and abuse or neglect. They were more likely than other treated youth to present with attention-deficit/hyperactivity and conduct disorders and less likely to have major depression. Findings provide preliminary evidence that parental incarceration may have a discrete negative effect on certain outcomes of treatment. 相似文献
