Diverse societal beliefs and redistributive policies, but equal welfare: The trade-off effect of information

Large empirical evidence shows that the difference in the political support for redistribution appears to reflect a difference in the social perceptions regarding the determinants of individual wealth and the underlying sources of income inequality. This paper presents a model of beliefs and redistribution which explains this evidence through multiple politico-economic equilibria. Differently from the recent literature which obtains multiple equilibria by modeling agents characterized by psychological biases, my model is based on standard assumptions. Multiple equilibria originate from multiple optimal levels of information for the society. Multiple optimal levels of information exist because increasing the informativeness of an economy produces a trade-off between a decrease in adverse selection and an increase in moral hazard. The framework allows to analyze various comparative statics in order to answer to policy questions

Beliefs and Redistributive Politics under Incomplete Information

The reason why the social contract is so different in two otherwise comparable societies like the United States and continental Western European countries represents a challenging question. Large empirical evidence shows that the difference in the political support for redistribution appears to reflect a difference in the social perceptions regarding the determinants of individual wealth and the underlying sources of income inequality. I present a model of beliefs and redistribution which explains this evidence through multiple politico-economic equilibria. Differently fromthe recent literaturewhich obtains multiple equilibria by modeling agents characterized by psychological biases, my model is based on standard assumptions. Multiple equilibria originate frommultiple optimal levels of information for the society. Multiple optimal levels of information exist because increasing the informativeness of an economy produces a trade-off between a decrease in adverse selection and an increase in moral hazard. The framework allows the analysis of various comparative statics in order to answer to policy questions.Politico-Economic Equilibria ; Redistribution ; Incomplete Information

THE RELATIONSHIP BETWEEN GIFTED AND UNGIFTED STUDENTS’ SELF-PERCEPTIONS AND THEIR PARENTS’ PARENTING STYLES: A STRUCTURAL EQUATION MODEL

The aim of this study is to reveal the influence of parental child rearing methods on self-perceptions of gifted and ungifted students with structural equation modeling. To achieve this purpose, the study has been carried out in BİLSEM in Mersin city and in multiple elementary state schools. As a descriptive method, causal-comparative method has been used in this study. Accordingly, Demographic Information Questionnaire, Offer Self-image Questionnaire, Parenting Style Inventory have been applied to students. In statistical analysis, Mann Whitney U Test, The Kruskal Wallis H Tests, Chi-Square Test and Path Analysis Techniques have been used. As a result of the study, it is found out that self-perceptions of gifted students are higher than self-perceptions of ungifted students. In SEM (Structural Equation Modeling), parental child rearing methods related to gifted and ungifted students explain the students’ self-perceptions at a statistically significant level.  Article visualizations

Do Girls and Boys Perceive Themselves as Equally Engaged in School? The Results of an International Study from 12 Countries

This study examined gender differences in student engagement and academic performance in school. Participants included 3420 students (7th, 8th, and 9th graders) from Austria, Canada, China, Cyprus, Estonia, Greece, Malta, Portugal, Romania, South Korea, the United Kingdom, and the United States. The results indicated that, compared to boys, girls reported higher levels of engagement in school andwere rated higher by their teachers in academic performance. Student engagement accounted for gender differences in academic performance, but gender did not moderate the associations among student engagement, academic performance, or contextual supports. Analysis of multiple-group structural equation modeling revealed that perceptions of teacher support and parent support, but not peer support, were related indirectly to academic performance through student engagement. This partial mediation model was invariant across gender. The findings from this study enhance the understanding about the contextual and personal factors associated with girls' and boys' academic performance around the world

Evaluating requirements modeling methods based on user perceptions: a family of experiments

Numerous methods and techniques have been proposed for requirements modeling, although very few have had widespread use in practice. One drawback of requirements modeling methods is that they lack proper empirical evaluations. This means that there is a need for evaluation methods that consider both the theoretical and practical aspects of this type of methods and techniques. In this paper, we present a method for evaluating the quality of requirements modeling methods based on user perceptions. The evaluation method consists of a theoretical model that explains the relevant dimensions of quality for requirements modeling methods, along with a practical instrument with which to measure these quality dimensions. Basically, it allows us to predict the acceptance of a particular requirements modeling method in practice, based on the effort of applying the method, the quality of the requirements artifacts produced, and the user perceptions with regard to the quality of the method. The paper also presents an empirical test of the proposed method for evaluating a Rational Unified Process (RUP) extension for requirements modeling. That test was carried out through a family of experiments conducted with students and practitioners and provides evidence of the usefulness of the evaluation method proposed. © 2011 Elsevier Inc.

Model for Human, Artificial & Collective Consciousness (Part I)

Borrowing the functional modeling approach common in systems and software engineering, an implementable model of the functions of human consciousness proposed to have the capacity for general problem solving ability transferable to any domain, or true self-aware intelligence, is presented. Being a functional model that is independent of implementation, this model is proposed to also be applicable to artificial consciousness, and to platforms that organize individuals into what is defined here as a first order collective consciousness, or at higher orders into what is defined here as Nth order collective consciousness. Part I of this two-part article includes: Summary; Introduction; Set of Postulates One; Set of Postulates Two; Overview of the Model; Model of Homeostasis; Model of the Functional Units; Model of the Body System; Model of the Other Basic Life Processes; Model of the Other Functional Systems; Model of Perceptions in the Perceptual Fields; Model of Body Processes as Paths in the Perceptual Field; & Model of Conscious Awarenes

The role of involvement with public transport in the relationship between service quality, satisfaction and behavioral intentions

Several studies have made manifest that involvement with public transport play a key role in the intentions of its use. However, conflicting models exist in the literature about involvement’s role in the relationship between service quality, satisfaction and behavioral intentions or loyalty. Previous studies suggest all possible roles: antecedent, mediator, moderator and direct effects. A structural equation modeling approach is applied here to further understand the role of involvement with public transport, comparing eight alternative models and using data from a single survey carried out in five European cities (Madrid, Rome, Berlin, Lisbon and London). Later, the study uses a multiple indicators and multiple causes structural equation modeling approach (SEM-MIMIC) to analyze the effect of heterogeneity present in the data over the four constructs considered (service quality, satisfaction, involvement and behavioral intentions). This comprehensive methodological approach provides a number of noteworthy findings, including the empirical verification that satisfaction is a full mediator between service quality and involvement, and involvement is a full mediator between satisfaction and behavioral intentions. The results further suggest that involvement is the factor that contributes most to behavioral intentions or loyalty, followed by service quality perceptions and satisfaction. Lastly, this study demonstrates the relevance of controlling for heterogeneity in users’ perceptions, so as to obtain more robust relations among factors and identify significant differences among market segments, which could prove useful for public transport operators or policy makers.Spanish Ministry of Economy and Competitiveness (Research Project TRA2015-66235- R

Changing an Unfavorable Employment Reputation: A Longitudinal Examination

Although a favorable employment reputation plays an important role in generating a large and qualified pool of job applicants for an organization (Rynes & Cable, 2003), little research has investigated whether organizations can improve applicants’ existing unfavorable employment reputation perceptions. Results from a four-week longitudinal experiment using 222 student job seekers revealed that participants’ employment reputation perceptions improved after exposure to recruitment practices and followed diminishing returns trajectories over time. High information recruitment practices (e.g., personal communication from a recruiter) from both single and multiple sources were more effective for changing unfavorable employment reputation perceptions than repeated mere exposure to the organization (i.e., exposure to only the company logo), and high information practices from multiple sources were the most effective overall. Finally, participants reporting less familiarity with the organization experienced greater reputation change across the four weeks, but only for participants in the mere exposure condition
