Moment matrices in conditional heteroskedastic models under elliptical distributions with applications in AR-ARCH models

It is well known that moment matrices play a very important rôle in econometrics and statistics. Liu and Heyde (Stat Pap 49:455–469, 2008) give exact expressions for two-moment matrices, including the Hessian for ARCH models under elliptical distributions. In this paper, we extend the theory by establishing two additional moment matrices for conditional heteroskedastic models under elliptical distributions. The moment matrices established in this paper implement the maximum likelihood estimation by some estimation algorithms like the scoring method. We illustrate the applicability of the additional moment matrices established in this paper by applying them to establish an AR-ARCH model under an elliptical distribution.     

The Quality of Social Networks: Its Determinants and Impacts on Helping and Volunteering in Macao

Pro-social behaviors serve essential societal functions. This study examines the factors affecting the quality of social networks, in terms of network size and perceived respect. It further explores the role of social networks in enhancing helping intention and helping behaviors. Eight hundred and eighty people were randomly interviewed by phone. Results indicated that the level of social participation, trust, and social identification were positively related to the quality of the social networks. A better social network was related to a higher level of helping intention and longer hours of volunteer works.     

The Volunteer Satisfaction Index: A Validation Study in the Chinese Cultural Context

Using a Hong Kong-sourced sample of 261 participants, this study set out to validate the Volunteer Satisfaction Index (VSI) in the Chinese cultural context and to evaluate its psychometric properties. The VSI was originally developed by Galindo-Kuhn and Guzley (2001) to measure the outcomes of volunteer experiences. In this study, exploratory factor analysis (EFA) yielded a different factor structure from that proposed by the scale developer. The three factors found were personal gain, relationship within organization and relationship with peers. Cronbach’s alpha values were high for all three subscales. Results from correlation and regression analysis also confirmed the construct and criterion-related validity of the scale. Thus, the reliability and validity of the scale were confirmed. Implications for the assessment of volunteer satisfaction and further directions for cross-cultural studies on related topics are discussed.     

Administrative Buy-in for User Participation in Managing Social Services

Abstract

This paper reports the findings of a study conducted in Hong Kong on the value position of the social service providers regarding user participation in service management. Using a survey instrument to collect data from 642 service providers in an elderly service organization, the study explored whether or not the value position had an effect on the views of the service providers on the structural set-up for user participation, and whether the value position of the professional staff was significantly different from that of the non-professional staff. Exploratory factor analyses (EFA), confirmatory factor analyses (CFA) and structural equation modeling (SEM) were applied in the analysis. The findings identify that administrative buy-in needed to support shared decision-making with the welfare service users has not been achieved in the studied organization, owing to the absence of value commitment to the user participation cause. As the professional staff was more supportive of values favoring user participation, the paper calls for an acculturation process that would be stimulated and led by professionals to develop a participatory culture. The paper also recommends conducting similar study on a larger scale and qualitative inquiry into factors influencing the formation of values about user participation in future research.     

Historical trajectories and lost heritage of early Chinese schools in Singapore – case study of Yeung Ching School in ‘Chinatown’

ABSTRACT

The history of modern Chinese schools in Singapore may be traced back to the early 20th century, when efforts to provide vernacular education in the British colony were made by community leaders across Chinese dialect groups, with support of the Qing Empire. Only a handful of these were selected as elite schools for bilingual education under the Special Assistance Plan (SAP) introduced in 1979 in independent Singapore. This paper examines the historical trajectories of these early schools from early association with Chinese nationalism to becoming multi-ethnic schools or simply defunct. It will focus on the case of the former Yeung Ching School in ‘Chinatown’ catering to the Cantonese community, to explore how the legacy of a Chinese school may be impacted by state formation and urban development since the 1950s, and also to point out a gap in current heritagisation pertaining to the role of education in shaping cultural identities.     

Emotion understanding and maternal sensitivity as protective factors against hostile attribution bias in anger‐prone children

The present research examined children’s anger proneness, emotion understanding, and maternal sensitivity during toddlerhood as predictors of children’s hostile attribution bias (HAB) during the later preschool years. At 2.8 years (N = 128), maternal sensitivity (e.g., child‐centered behavior) was observed during mother–child play and snack, and parents reported on children’s anger proneness. At 3.3 years, emotion understanding (i.e., ability to identify emotional expressions accurately) was measured via an interactive puppet interview. At 4.8 and 5.4 years, children's HAB was assessed via child responses to hypothetical vignettes of ambiguous peer provocations. Path models revealed that maternal sensitivity predicted fewer hostile attributions. In addition, emotion understanding and maternal sensitivity emerged as buffers against the negative effect of anger proneness on HAB. Specifically, greater anger proneness was associated with more frequent hostile attributions, but only when children had lower emotion understanding or had mothers who were less sensitive. The findings highlight the interplay between intrapersonal and interpersonal factors in early childhood that contribute to a hostile attribution bias during the preschool period.     

Innovation by Teams in Shanghai,China: Cooperative Goals for Group Confidence and Persistence*

Organizations increasingly ask teams to stimulate innovation but research is needed to identify the conditions when teams have the confidence and persistence to innovate successfully. Using the concepts of cooperation, competition, group potency and initiative, this study proposes that relationships where team members believe that their goals are cooperative in that one person's goal attainment helps others reach their goals lay the foundation for innovation. Specifically, cooperative goals convince team members that they have the group potency to complete a range of tasks and the initiative to persist to overcome obstacles and innovate. In contrast, competitive, negatively related goals and independent, unrelated goals are hypothesized to undermine confidence, persistence and innovation. Group members from 101 teams from various organizations in Shanghai, China, completed a survey with measures of cooperative, competitive and independent goals, group potency, and initiative; their project leader completed the measure of innovation. Structural equation analysis supports the theoretical framework that cooperative goals help group members develop the confidence of group potency and the initiative to persist to accomplish tasks and innovate. These results suggest that cooperative goals and group potency and initiative are important conditions that help teams innovate for organizations and thereby specify conditions that can help groups realize their potential to achieve innovation for organizations.     

Comparing income poverty gap and deprivation on social acceptance: A mediation model with interpersonal communication and social support

In many developed countries or regions, wide income disparities increase the difficulty in reducing poverty. In their day‐to‐day lives, poor people often feel less accepted by the society. The failures in communicating with social groups and receiving social support lead to negative consequences on individual well‐being and higher level of social exclusion. Based on the debate upon alternative approaches to conceptualizing and operationalizing poverty, this study attempts to verify a mediation model with data from a household survey (N = 1,202) in Hong Kong. The results of structural equation modelling reveal that deprivation is a more powerful indicator than income poverty for specifying the negative relations of poverty with interpersonal communication, social support, and social acceptance; the negative impact of deprivation on social acceptance can be reduced by two significant mediators of interpersonal communication and social support. The results are discussed in terms of directions for future research and policy and welfare intervention.     

Parents' Experiences During the Family Reunification Process: A Chinese Context

Family reunification is always an integral part of a permanency plan and is a preferable outcome for children in care. However, reunification is not straightforward, involving many subsequent negotiations between parents, children, and social workers, sparking various emotions and struggles among the involved parties. Current research on parental experiences of family reunification is predominantly of a cross‐sectional nature, and rarely reflects the parents' experience throughout the process. This paper reports the results of a qualitative panel study aimed at exploring the experiences Chinese parents have during the process of children returning home from care. Seven parents were recruited. Data was collected at three time points and informants narrated their experiences from both a retrospective and prospective perspective. The findings showed that all parents struggled to become competent caregivers. Three salient themes were identified: inferiority, adjustment, and challenge. The parents' experiences revealed the prevalence of stigmatization among social work professions toward parents. This study recommends re‐focusing the policy direction and intervention strategies of out‐of‐home care from family coercion to family support.
