When consumers make purchase decisions, they generally refer to the reviews generated by other consumers who have already purchased similar products in order to get more information. Online transaction platforms provide a highly convenient channel for consumers to generate and retrieve product reviews. In addition, consumers can also vote reviews perceived to be helpful in making their decision. However, due to diverse characteristics, consumers can have different preferences on products and reviews. Their voting behavior can be influenced by reviews and existing review votes. To explore the influence mechanism of the reviewer, the review, and the existing votes on review helpfulness, we propose three hypotheses based on the consumer perspective and perform statistical tests to verify these hypotheses with real review data from Amazon. Our empirical study indicates that review helpfulness has significant correlation and trend with reviewers, review valance, and review votes. In this paper, we also discuss the implications of our findings on consumer preference and review helpfulness. 展开更多

In recent years,Francophone schools in Alberta,a province in western Canada,have seen significant ethnocultural diversification of their school population,thus reflecting recent migratory changes in Canada.The population of a Francophone school board located in an agglomeration of Alberta reflects these new migratory trends.A partial ethnodemographic portrait carried out in 2003 in six of its schools indicates that 50%of the pupils come from an immigrant background and come from 23 different countries;mostly from sub-Saharan African countries.This demographic reality,confirmed more than a decade later,represents a major structural change for Francophone schools.In Alberta,as in other Canadian provinces,inclusion is at the heart of discourse and educational practices.With a transformative aim,it intends to promote ethnocultural diversity in the classroom and equal opportunities through school equity practices.This article focuses on the settlement workers in schools responsible for bridging family,community,and school cultures.The analysis of the interviews of the four workers sheds light on and questions both the institutional practices and the personal strategies put in place to face the challenges encountered in this tripartite collaboration. 展开更多

Adolescents’emotions and preferences are influenced by their childhood experiences.In today’s world,there is a pervasive eagerness for happiness.Happiness has been linked to feelings of self-strength,seeking help,and psy-chological health.The current quantitative research was designed with a positive psychological perspective to compare Pakistani and Chines adolescents’self-strength,seeking help,and happiness.The research design of the study was causal-comparative.The study population consisted of 400 Pakistani and 409 Chinese adolescents studying in the elementary grades of both countries.The sample was selected by using a simple random sampling technique.It consisted of 413 boys(51%)and 396 girls(49%),319(39)of them were from the age group of 13–14 years,386(48%)of them were from the age group of 15–16 years,and 104(12.9%)were from the age group of 17–18 years.Three different scales were developed to collect study data.Independent sample t-test and simple linear regression were used to test study hypotheses.The analysis revealed that Pakistani adolescents have signifi-cantly higher self-strength,seeking help and happiness than their counterparts.It was also found that adolescents’self-strength and seeking help significant affect their happiness.Based on thefindings,it was suggested to inves-tigate the factors contributing to the improved self-strength,seeking help,and happiness of Pakistani adolescents.It was also recommended to investigate the mediating effect of adolescents’self-strength on the relationship between their happiness and seeking help. 展开更多
