Theoretical elastoplastic analysis for foundations with geosynthetic-encased columns

As a new technique in ground improvement, geosynthetic-encased columns (GECs) have promising applications in soft soil foundation. By assuming yielding occurs in the columns while the surrounding soil and the geosynthetic remain elastic, an elastoplastic analytical procedure for foundations improved by GECs is proposed. The radial stresses that the geosynthetic provides and the elastoplastic deformations of the foundation resting on a rigid base are derived. A comparison with finite element analysis shows that the proposed method is effective and can provide a reasonable prediction of a GEC??s deformation. Subsequent parametric analysis indicates that higher geosynthetic stiffness leads to better performance of the composite foundation. The optimum length of encasement is related to the load acting on the foundation and the permissible vertical and radial displacements of the column. Moreover, as the dilation angle of the column increases, the settlement decreases, especially under high loading. The influence of the encasement is more significant in soils with smaller elastic modulus.     

DEPRESSION AND RELATIONAL HEALTH IN ASIAN AMERICAN AND EUROPEAN AMERICAN COLLEGE WOMEN

Research consistently demonstrates elevated rates of depression among college‐aged women, yet evidence of racial differences in depression among this population are poorly understood. Moreover, the correlates of depression among Asian American women are also understudied. In this exploratory analysis, we examined mean differences in depression levels in a sample of Asian American (n = 117) and European American (n = 257) students from a women's liberal arts college. We also estimated associations between depression and relational health in three types of relationships (mentor, friend, and college community) using ordinary least squares regression. Relational health was examined as a buffer (i.e., moderator) against depression. Results indicated no differences in depression levels between Asian American and European American women. Relationships with the college community were associated with lower levels of depression in both groups of women. Limited evidence suggested that relational health served as a buffer. Results are discussed in light of interventions for college campuses.

Echoslamming: how incivility interacts with cyberbalkanization on the social media in Hong Kong

Cyberbalkanization has growingly become common on the Internet and can lead to public’s opinion polarization. This study investigates a specific process of cyberbalkanization through which incivility is circulated within online communities. From a dataset of Hong Kong-based Facebook Pages collected during a social movement, a set of politically-organized communities was identified and their connectivity generated a post-sharing network. A random sample of contents shared between and within these communities was then manually classified based on the level of incivility. The targets of offence through the use of uncivil language were also coded. Contents shared within ideologically compatible communities were found to be more likely to be uncivil. The association was significantly more positive in a populistic community, of which members had unique political nature and cultural norms. The targets were usually political opponents and incivility was adopted to petition detractors from within-community discussions. We therefore suggest ‘echoslamming’ is an online phenomenon through which uncivil contents catalyse anger toward political opponents among ideologically congruent information sources and consequently reinforce the audience’s predilection. Such a mechanism can be one underlying explanation for a vicious circle of cyberbalkanization-induced polarization on political opinions.     

Effects of a phonological awareness program on English reading and spelling among Hong Kong Chinese ESL children

This study investigated the effects of a 12-week language-enriched phonological awareness instruction on 76 Hong Kong young children who were learning English as a second language. The children were assigned randomly to receive the instruction on phonological awareness skills embedded in vocabulary learning activities or comparison instruction which consisted of vocabulary learning and writing tasks but no direct instruction in phonological awareness skills. They were tested on receptive and expressive vocabulary, phonological awareness at the syllable, rhyme and phoneme levels, reading, and spelling in English before and after the program implementation. The results indicated that children who received the phonological awareness instruction performed significantly better than the comparison group on English word reading, spelling, phonological awareness at all levels and expressive vocabulary on the posttest when age, general intelligence and the pretest scores were controlled statistically. The findings suggest that phonological awareness instruction embedded in vocabulary learning activities might be beneficial to kindergarteners learning English as a second language.     

Teacher experiences of culture in the curriculum

This study examines the experiences of two middle‐school teachers as they attempt to acknowledge the ethnic, linguistic, and religious diversity of their students in their curriculum and teaching practices. It identifies the complications and challenges they encountered in the process. It presents one curriculum event to explore the ways in which diverse beliefs and values intersected as the teachers implemented the event. It employs a narrative inquiry approach with an emphasis on stories to learn about the experiences of the participants.     

Reducing anxiety in gifted children by inducing relaxation

Sixty-four parents of Chinese gifted children who reported themselves to be traditional or Westernized parents were compared on their endorsement of Chinese traditional and Western parenting values and beliefs as well as their parenting style dimensions in terms of dominating control, guan, and warmth. Regardless of their degrees of Westernization, these parents seemed to be more characterized by collectivistic than individualistic thinking approaches based on Nisbett's conceptualization. More Westernized parents valued nonconformity significantly more than conformity, whereas less-Westernized parents placed more emphasis on the importance of unconditional respect for elders and interdependence than on conditional respect and child independence. Regarding parenting styles and practices, though all parents endorsed the practice of warmth significantly more, followed by guan, and significantly less dominating control, there was suggestive evidence that less-Westernized parents practiced guan more than more-Westernized parents. Implications of the findings for parenting gifted children are discussed.
