Metalinguistic skills and vocabulary knowledge in Chinese (L1) and English (L2)

How are metalinguistic skills associated with vocabulary knowledge in languages with contrasting phonological and morphological properties? To address this question, tasks of phonological awareness and morphological awareness, other reasoning and literacy-related skills, and measures of vocabulary knowledge in Chinese and English, were administered to 217 Hong Kong Chinese kindergarten children learning English as a second language. Syllable-level awareness but not phoneme onset awareness was strongly associated with Chinese vocabulary knowledge; phoneme onset awareness but not syllable awareness was associated with English vocabulary knowledge. In hierarchical regression equations, phonological awareness in English explained unique variance in English vocabulary knowledge but not in Chinese vocabulary knowledge. In contrast, measures of morphological awareness, which were strongly associated with syllable awareness, uniquely explained 13% of the variance in Chinese vocabulary knowledge apart from all other measures included but were not uniquely associated with English vocabulary knowledge. Findings highlight the strong overlap across phonological and morphological awareness in Chinese and the different associations of each to vocabulary acquisition in Chinese (L1) and English (L2) languages.     

Religious engagement and attitudes to the role of religion in society: their effect on civic and social values in an Asian context

This paper explored the impact of religious engagement (religious background, religious service attendance and religious activities participation) on adolescents’ civic and social values. Attitudes towards the influence of religion on society were investigated as a possible mediator/moderator of religious engagement. A model based on Western literature was tested using a sample of over 2000 Hong Kong students. Secondary data were drawn from the International Civics and Citizenship Education Study 2009. Multi-level modelling was used to assess individual and school level effects on civic and social values. Results indicated that religious engagement exerted varied effects. Religious background showed small and negative effects on students’ civic and social values. Participation in religious services indicated a small, positive and significant effect on social but not on civic values. Participation in religious activities showed no significant effect on either social or civic values. These variables exerted a small moderating effect on social and civic values through attitudes to the influence of religion on society. The latter exerted a positive and significant effect on civic values and a negative effect on social values. These results suggested that Western models depicting the positive relationship between religious engagement and citizenship values may not hold for Asian societies.     

Small, medium and large hypertext

This paper critically reviews the different types of abstractions and implementations in the hypertext area and proposes that three types of hypertext exist, namely, small-, medium- and large-volume hypertext. For a single person dealing with a single text the prominent issue is the model of the text that the user browses; this is small-volume hypertext. When a few people are involved in creating a few texts, records are maintained as to who created what and when; this is medium-volume hypertext. In large-volume hypertext the document collection is massive and special institutions are responsible for filtering and indexing material against which arbitrarily many other people issue searches. All these aspects of hypertext have in common an abstraction of text as a graph rather than a line and an ultimate goal of facilitating communication among people.     

Power in Bayesian Mediation Analysis for Small Sample Research

Bayesian methods have the potential for increasing power in mediation analysis (Koopman, Howe, Hollenbeck, & Sin, 2015; Yuan & MacKinnon, 2009). This article compares the power of Bayesian credibility intervals for the mediated effect to the power of normal theory, distribution of the product, percentile, and bias-corrected bootstrap confidence intervals at N ≤ 200. Bayesian methods with diffuse priors have power comparable to the distribution of the product and bootstrap methods, and Bayesian methods with informative priors had the most power. Varying degrees of precision of prior distributions were also examined. Increased precision led to greater power only when N ≥ 100 and the effects were small, N < 60 and the effects were large, and N < 200 and the effects were medium. An empirical example from psychology illustrated a Bayesian analysis of the single mediator model from prior selection to interpreting results.     

Influence of deviant behaviours in workgroups in relation with group composition

The potential for behaviourally challenged students to negatively impact typically developing students is a concern shared by many parents and teachers. However, deviant peer influence during workgroup activities has not been thoroughly investigated through systematic observation of deviant interactions. This study compares sequences of deviant behaviours and peer responses recorded during cooperative activities. Seventy fifth-grade elementary school students were observed in three specific contexts, homogeneous EBD workgroups, homogeneous regular workgroups and inclusive workgroups. Findings reveal a greater prevalence of verbal aggressions and more explosive exchanges in EBD workgroups. In groups consisting solely of typically developing students, intentionally ignoring disruptive teammates proved to be effective in stopping deviant behaviours. Finally, it was in inclusive workgroups that observed deviant interactions sequences were the longest. These findings are discussed in relation with the role of group composition and workgroup training in fostering effective cooperative learning environments.     

Venture finance,small firms and public policy in the UK

During the tenure of the current Conservative administration, public policy in Britain has very much favoured the smaller firm. This policy emphasis appears to be based on a belief in the superior job creating potential and innovatory capacity of smaller firms over their larger counterparts. Evidence presented in the paper shows that small firms have, indeed, made an important contribution to innovation in the UK and that their share of significant British innovations has increased significantly since the mid-1970s. An important aspect of small firm policy in the UK has been the introduction of several schemes designed to increase the flow of capital into the small firm sector, with special emphasis being placed on venture capital. The first of these schemes, the Loan Guarantee Scheme, has directed capital from the banks into over 14,000 small firms. The second scheme, the Business Expansion Scheme, has increased significantly the overall flow of venture capital and has biased investments towards start-up and early stage financing. These two schemes, together with the establishment of an Unlisted Securities Market, have provided some impetus to the development of private sector venture capital in Britain, which is growing apace. Essentially, the public sector schemes have underwritten the costs of entry to the venture capital market of both individual and institutional investors. In other words, they have had an important catalytic effect in stimulating the growth of private sector venture capital industry which is now the largest in Europe.     

Protective Role of Bilirubin Against Increase in hsCRP in Different Stages of Hypothyroidism

In conjunction with thyroxine, bilirubin may play an important role for regulation of hsCRP level and a consequent pro-inflammatory condition in hypothyroidism. In present study we evaluated the dependence of hsCRP changes on total bilirubin (BT) and fT4 level in thirty overt (OH) and thirty subclinical hypothyroidism (SH). Serum BT, hsCRP, thyroxine and TSH were measured in both groups and compared with forty control subjects. Serum values of TSH, hsCRP showed raised (P < 0.001 for both) values with lower levels for fT4 and BT (P < 0.001 and 0.03 respectively) in hypothyroid patients compared to the controls. ANOVA showed significant increments in TSH and hsCRP values with decreases in fT4 among the control, SH and OH groups respectively (P < 0.001). BT values showed decrease in OH group only in comparison to controls (P = 0.04). Regression analysis revealed that hsCRP was negatively dependent on fT4 (β = −0.35, P = 0.002) and serum bilirubin (β = −0.40 and P < 0.001 respectively). Univariate general linear model analysis showed this dependence persisted even when carried out distinctly in SH and OH groups separately (P < 0.001). TSH did not show any significant predictive value on the hsCRP level in either of these two tests. From these analyses we suggest that serum hsCRP is closely integrated to a lowered synthesis of bilirubin and fT4 in hypothyroid patients. Furthermore, this causal relationship is not only limited to overt but also extends to the SH.
