Divergence Behaviour of the Successive Geometric Mean Method of Pairwise Comparison Matrix Generation for a Multiple Stage,Multiple Objective Optimization Problem

This paper focuses on the divergence behaviour of the successive geometric mean (SGM) method used to generate pairwise comparison matrices while solving a multiple stage, multiple objective (MSMO) optimization problem. The SGM method can be used in the matrix generation phase of our three‐phase methodology to obtain pairwise comparison matrix at each stage of an MSMO optimization problem, which can be subsequently used to obtain the weight vector at the corresponding stage. The weight vectors across the stages can be used to convert an MSMO problem into a multiple stage, single objective (MSSO) problem, which can be solved using dynamic programming‐based approaches. To obtain a practical set of non‐dominated solutions (also referred to as Pareto optimal solutions) to the MSMO optimization problem, it is important to use a solution approach that has the potential to allow for a better exploration of the Pareto optimal solution space. To accomplish a more exhaustive exploration of the Pareto optimal solution space, the weight vectors that are used to scalarize the MSMO optimization problem into its corresponding MSSO optimization problem should vary across the stages. Distinct weight vectors across the stages are tied directly with distinct pairwise comparison matrices across the stages. A pairwise comparison matrix generation method is said to diverge if it can generate distinct pairwise comparison matrices across the stages of an MSMO optimization problem. In this paper, we demonstrate the SGM method's divergence behaviour when the three‐phase methodology is used in conjunction with an augmented high‐dimensional, continuous‐state stochastic dynamic programming method to solve a large‐scale MSMO optimization problem.

佛教幸福感的心理学解读：基于中西比较的视角

幸福感是文化定位的,因此幸福感的研究必须本土化.佛教是影响中国人最重要的三种文化传统之一,正确理解佛教独特的对于幸福感的理解也能够进一步推动幸福感研究的本土化进程.笔者通过对佛教教义的梳理,重点阐述了佛教对幸福的认识是“苦乐圆融”.佛教“苦乐圆融观”主要从“苦受”和“乐受”两方面入手,其核心是“苦受”,关键在“圆融”.最后,通过与西方幸福感研究的比较,加深对佛教“苦乐圆融观”的理解.佛教幸福感的研究作为一个新思路,不但丰富了幸福感的研究,也为今后进一步的研究提供了一定的依据.     

Engagement,Flow, Self-Efficacy,and Eustress of University Students: A Cross-National Comparison Between the Philippines and Argentina

This study examined how self-efficacy, eustress, and flow interact with academic engagement. First, it aimed to test a theoretical model that proposes that self-efficacy and eustress promote both flow and engagement and that, in turn, the state of flow promotes academic engagement in undergraduate student. We hypothesized that the theoretical model would be invariant for two countries: the Philippines and Argentina. Secondly, this research aimed to compare the levels of self-efficacy, eustress, study-flow and academic engagement experiences in students from both countries. One hundred seventy-six Filipinos and 171 Argentinean students participated in the study by completing inventories using the Utrecht Student Engagement Scale (Schaufeli, Martínez, et al., 2002), Optimal Experience Survey (Mesurado, 2008), Self-efficacy Scale (O’Sullivan, 2011), and Eustress Scale (O’Sullivan, 2011). Results show that the theoretical model fits the data well in both countries and is invariant across the Philippines and Argentina. Self-efficacy has a positive effect on flow and engagement, whereas eustress has a significant positive relationship with flow but is not directly associated with engagement. However, eustress has an indirect effect, through flow, on student engagement. On the other hand, there are different levels of engagement, flow, self-efficacy, and eustress. Argentinean students scored higher on absorption, dedication, self-efficacy, and flow. Filipino students, meanwhile, scored higher on eustress.     

Self-Oriented Body Comparison and Self-Compassion: Interactive Models of Disordered Eating Behaviors Among Postpartum Women

Evidence suggests self-oriented body comparison (comparison of one’s postpartum body shape and weight to one’s prepregnant body shape and weight) is a critical factor associated with increased levels of disordered eating during the postpartum period. However, some postpartum women adopt a self-compassionate and acceptance-based perspective toward their body shape and weight changes. It is unclear whether self-compassion may buffer the associations between self-comparisons and disordered eating behaviors among postpartum women, which is the aim of the current study. A total of 306 postpartum women who gave birth in the past year completed an online survey asking about self-compassion, social comparison, broad eating pathology, dietary restraint, and binge eating. Results indicated that self-compassion appeared to buffer the associations between self-comparison and broad eating pathology and binge eating among postpartum women, such that for women with above-average levels of self-compassion, the associations between self-comparison and disordered eating was weaker than for women with average or below-average levels of self-compassion. Findings suggest self-compassion could be a potential target for intervention programs.     

基于社会文化规范下的自我调控过程的中日比较

该研究通过个体对社会规范的积极性认同态度与行动意向的关联程度,建立自我调控过程中社会文化性差异的假设模型。对日本大学生（305人）、中国大学生（384人）、中国大学生父（或母,329人）进行社会规范认同态度及行动意向问卷调查,利用AMOS软件进行了多组比较的结构方程模型的协方差结构分析,结果显示：1）在血缘关系性社会规范方面,日本大学生、中国大学生、中国大学生父母三群体积极性认同态度对行动意向影响无显著差异;2）在社会职责性社会规范方面,日本大学生、中国大学生、中国大学生父母三组间的积极性认同态度与行动意向关联差异显著。日本大学生对于社会职责性社会规范进行更有效的自我调控;3）除两国间文化差异以外,中国大学生与其父母间对于（最初预想以外的第三因素）自我付出性社会规范的自我调控过程也呈现显著差异。     

The contrasting effects of negative word of mouth in the post-consumption stage

We explore the effects of negative word of mouth (NWOM) from worse-off or similar others in the post-consumption stage. In four experiments, we show that the ramifications of NWOM are more complex than portrayed in the literature. Specifically, we demonstrate that attribute-based NWOM has a negative (i.e., aggravating) effect on dissatisfied consumers, whereas experience-based NWOM has a positive (i.e., alleviating) effect. Thought-listing data reveal distinct processes underlying the contrasting effects. On one hand, these results are consistent with the predictions of attitude polarization and downward comparison research. On the other hand, they are explainable in terms of the disconfirmation model.     

Who is crossing where? Infants' discrimination of figures and grounds in events

To learn relational terms such as verbs and prepositions, children must first dissect and process dynamic event components. This paper investigates the way in which 8- to 14-month-old English-reared infants notice the event components, figure (i.e., the moving entity) and ground (i.e., stationary setting), in both dynamic (Experiment 1) and static representations of events (Experiment 2) for categorical ground distinctions expressed in Japanese, but not in English. We then compare both 14- and 19-month-old English- and Japanese-reared infants’ processing of grounds to understand how language learning interacts with the conceptualization of these constructs (Experiment 3). Results suggest that (1) infants distinguish between figures and grounds in events; (2) they do so differently for static vs. dynamic displays; (3) early in the second year, children from diverse language environments form nonnative – perhaps universal – event categories; and (4) these event categories shift over time as children have more exposure to their native tongue.     

Properties of reverse hazard functions

For continuous distributions reverse hazard is defined as the probability density divided by the cumulative probability, F(x); whereas the usual hazard function is the density divided by the survivor function, 1−F(x). Reverse hazard corresponds to the conditional density of an immediate failure or state change, conditioned by the fact that the state change occurred. For example, of all the items that failed, the proportion of those items that immediately failed is reverse hazard. Reverse hazard exhibits many symmetrical properties with hazard. In this paper a set of theorems are developed that explicate the properties of reverse hazard for both continuous and discrete probability distributions. Taken together, hazard and reverse hazard are a powerful set of theoretical constructs that are valuable for understanding stochastic systems.     

The Roles of Praise and Social Comparison Information in the Experience of Pride

Abstract

The authors examined the roles of social comparisons, publicity of success, and praise on the experience of pride in an experiment in which college students successfully completed a timed intelligence task in private and later received 1 of 4 types of feedback from the experimenter: no feedback (private), mere public acknowledgment of completion, general praise containing both a public and an evaluative component, or praise containing explicit comparison information. Half of the participants also received written normative information suggesting they performed at a high level. Participants then completed a number of dependent measures, including a key measure of pride. Overall, results suggest that the public aspect of a performance, together with the superior standing suggested by any praise accompanying this publicity, is important in the experience of pride.
