The few studies on Family Language Policy in Singapore (FLP) have generally focused on FLP in local and immigrant Chinese families. This article explores language policies that seem to undergird Singaporean-Japanese families' language practices. In-depth interviews and observations with five such families showed that Japanese only functions as the language of communication between the Japanese parents and their children if parents have invoked particular language policies to support its transmission and use at home. For most families, English was the main medium of communication among family members. Language policies and practices in these families were heavily influenced by the value emplaced on each language within the parents' linguistic repertoire and their beliefs regarding language learning.

Not only does Singapore have a unique ethnic and multilingual makeup, it also boasts unique language policies, especially with regard to the learning of the official languages. Previous studies of Singaporean youths have largely focused on the differences in attitudes and code-switching between linguistic varieties (e.g. Colloquial Singapore English [Singlish] and Standard Singapore English) as well as looking at the specific languages of Singapore's multilingual community. This paper seeks to examine how Chinese-Singaporean youths differ in their perception of the benefits (general, communicative, cognitive and pragmatic) and disadvantages associated with Mandarin-English bilingualism and their Chinese-Singaporean identity. 165 Chinese-English bilingual youths from secondary schools, Polytechnics/Junior Colleges, University undergraduates and young working adults were stratified based their gender, socio-economic status and self-rated language proficiency. Our findings suggest that bilinguals' self-rated proficiency is generally the best indicator of local Chinese youths' attitudes towards Chinese-English bilingualism and identity, regardless of their current occupation, gender or socio-economic status.

Graphite matrix/copper composites have found significant potential uses in numerous areas. Until now, a high ambient gas pressure has to be applied to overcome the non-wettability between the copper melt and graphite matrix, which has restricted the technological and economic efficiencies, as well as the composite performance. In this paper, we have proposed a pressureless infiltration strategy to realize the preparation of highly conductive graphite matrix/copper composites. A tungsten carbide network is first in situ constructed in the graphite matrix, transforming the capillary force from the resistance mode to the impetus mode. Results show that the contact angle of graphite/copper decreased from 138.5° to 23° due to the constructed tungsten carbide network. The composites exhibit good interfacial bonding, and the electrical conductivity reaches 15.1 × 105 S/m, far higher than the requirement of the industry standard. [ABSTRACT FROM AUTHOR]

In this paper, CoFe2 O4/biomass carbon composts were prepared by one-pot hydrothermal and high- temperature calcination methods. The microscopic morphology, crystal structure and electromagnetic parame¬ters of the material indicate that CoF2 O4can be uniformly dispersed in the carbon base, and the presence of CoFe2 O4 is conducive to the defective polarization of the biomass during the carbonization process, which is ben racial to the enhancement of the wave absorption properties of the material. Effective regulation of the electro¬magnetic parameters of the composite material by adjusting the content of CoFe2 O4 to optimize tots impedance match mg performance. Experimental results show that the minimum reflection loss (reflection loss, RL) value of-48.0 dB and effective absorption bandwidth (effective absorption bandwidth, EAB) of 5.5 GHz were ob. turned at 2.0 mm thickness of Co2 O4O4/C-3.0 composite.

This study investigates how bicultural switching could influence cognitive performance on Executive Functions tasks among bicultural-bilinguals.Study 1 (n = 233) integrates self-report questionnaire data on cultural and language behaviour with a priming experiment, providing empirical evidence of young adult bilinguals’ ability to shift between multiple cultures.Study 2 (n = 48) explores the effect of cultural switching frequency on young adult bicultural bilinguals’ performance on tests for interference and inhibition control, set-shifting ability, and attention.Study 1: A repeated measures ANOVA was conducted to determine the effect of different primes on participant’s ratings. We ran a two-way mixed ANOVA to ascertain the effect of interlocutors (Grandparents/relatives, Parents, Siblings, Peers/co-workers, Social media) on behaviour (Cultural, Language). Study 2: A one-way ANOVA was conducted on Simon, Flanker, and Wisconsin Card Sort tasks (WCST). Each of the three attention network components was analysed using a 2 (trial-type, within-subjects) × 2 (Switching Group, between-groups) mixed-ANOVA for the Attention Network task.Study 1: Participants who alternate frequently between cultural frames made a clearer distinction between Western primes than those who switched between cultural frames less, suggesting that the frequency of cultural switching could impact cognition. Study 2: Bicultural bilinguals who switched between cultural frames frequently resolved stimulus-response conflict significantly faster in the Flanker task, made fewer mistakes within each sorting block in the WCST, and had a smaller conflict effect compared to infrequent switchers in the Attention Network Task.This study examines the effects of bicultural switching on Executive Functions of highly proficient bicultural bilinguals, highlighting it as a potential confound in bilingual research. Bicultural switching effects on interference and inhibition-control persist even in participants at the developmental peak of their cognitive processing capabilities after controlling for a plethora of socio-linguistic variables. Our research highlights how this understudied aspect of multiculturalism may have broad implications for bilingual research in Executive Functions. [ABSTRACT FROM AUTHOR]
