    Description: This report compares the electroanalytical performances of single- (G-SL), few- (G-FL), and multilayer graphene (G-ML), graphite microparticles, and edge-plane pyrolytic graphite electrodes in terms of sensitivity, linearity, and repeatability. We show that in the case of differential pulse voltammetric (DPV) detection of ascorbic acid, the sensitivity of a G-SL electrode is about 30% greater than that of G-ML and about 40% greater than graphite microparticles. However, in the case of DPV determination of uric acid, sensitivity is practically the same for all (G-SL, G-FL, and G-ML) and, importantly, the graphite microparticles do provide higher sensitivity than graphenes do for this analyte. Graphenes also do not provide a significant advantage in terms of repeatability. We pose the question of whether the efforts leading to the bulk method of producing single-layer graphene are justified for electroanalytical applications.

    Description: Using a national survey of citizens during Singapore’s general election, this study finds that alternative online media filled information gaps and narrowed the knowledge gap between social status groups. Contrary to the original knowledge gap hypothesis, lower educated voters gained knowledge more rapidly from increased alternative media use than more highly educated voters. This indicates that the press system itself influences the knowledge gap. In authoritarian press systems, where mainstream news is regulated and framed to promote ruling party’s elite perspectives, alternative online information produced from the ground up embodies greater relevance and authenticity, facilitating greater knowledge gain among lower educated voters.

    Description: This article argues that Japan matters crucially in the evolving East Asian security order because it is embedded both in the structural transition and the ongoing regional strategies to manage it. The post-Cold War East Asian order transition centres on the disintegration of the post-Second World War Great Power bargain that saw Japan subjecting itself to extraordinary strategic constraint under the US alliance, leaving the conundrum of how to negotiate a new bargain that would keep the peace between Japan and China. To manage the uncertainties of this transition, East Asian states have adopted a three-pronged strategy of: maintaining US military preponderance; socializing China as a responsible regional great power; and cultivating regionalism as the basis for a long-term East Asian security community. Japan provides essential public goods for each of these three elements: it keeps the US anchored in East Asia with its security treaty; it is the one major regional power that can and has helped to constrain the potential excesses of growing Chinese power while at the same time crucially engaging with and helping to socialize China; and its economic and political participation is critical for meaningful regionalism and regional integration. It does not need to be a fully fledged, 'normal' Great Power in order to carry out these roles. As the region tries to mediate the growing security dilemma among the three great powers, Japan's importance to regional security will only grow.

    Description: Increasing attention is being paid to the specificities of Asian multiculturalism in relation to ethnic pluralism, citizenship and developmental state formation. This article examines these relationships by analysing three carnival events in colonial and postcolonial Singapore that were organized by the state to promote its official multiculturalism. Through its cultural logics of horizontal racial segmentation, cascading symbolic authority from the state to co-opted communal representatives and multi-modal ritual iteration, the 1937 King George VI coronation celebrations proffered an imperial multiculturalism based on mediating plural groups and procedural norms. Adopting the same cultural logics in the 1970s, the newly-independent nation-state revived and transformed Chingay, a creole Chinese religious procession, into an annual parade celebrating the nation as comprising racially plural groups bound together by the modern ethos of progress the developmental state exemplified. In the 2000s, Chingay has been turned into an international spectacle celebrating Singapore as a cosmopolitan global city of hybridizing multiculturalism. But indicative of new racial-class segmentation, the old nation-building pluralism is promoted by Racial Harmony Day carnivals held in suburban public housing neighborhoods. This bifurcated multiculturalism reflects the developmental state's attempts to deal with new citizenship trends as they grind against the old ethnic pluralism. While faced with the same issues globalization brings, this postcolonial multiculturalism is distinctively different from liberal multiculturalism, not least because the subvention of multiculturalism is achieved through the state appropriation of vernacular cultural practices through its carnivals.

    Description: Wnt signaling is mediated by three classes of receptors. Frizzled, Ryk, and Ror. In Caenorhabditis elegans, Wnt signaling regulates the anterior/posterior polarity of the P7.p vulval lineage, and mutations in lin-17/Frizzled cause loss or reversal of P7.p lineage polarity. We found that pak-1/Pak (p21-activated kinase), along with putative activators of Pak, nck-1/Nck, and ced-10/Rac, regulates P7.p polarity. Mutations in these genes suppress the polarity defect of lin-17 mutants. Furthermore, mutations in pak-1, nck-1, and ced-10 cause constitutive dauer formation at 27°C, a phenotype also observed in egl-20/Wnt and cam-1/Ror mutants. In HEK293T cells, Pak1 can antagonize canonical Wnt signaling. Moreover, overexpression of Ror2 leads to phosphorylation of Pak1. Together, these results indicate that Pak interacts with Wnt signaling to regulate tissue polarity and gene expression.

    Description: With increasing recognition that maximum oxygen demand is the unifying limit in tolerance, the first line of thermal sensitivity is, as a corollary, due to capacity limitations at a high level of organisational complexity before individual, molecular or membrane functions become disturbed. In this study the tropical mussel were subjected to temperature change of 0.4 °C per hour from ambient to 8–36 °C. By comparing thermal mortality against biochemical indices (hsp70, gluthathione), physiological indices (glycogen, FRAP, NRRT) and behavioural indices (clearance rate), a hierarchy of thermal tolerance was therein elucidated, ranging from systemic to cellular to molecular levels. Generally, while biochemical indices indicated a stress signal much earlier than the more integrated behavioural indices, failure of the latter (indicating a tolerance limit and transition to pejus state) occurred much earlier than the other indices tending towards thermal extremities at both ends of the thermal spectrum.

In this experience-sampling study, 135 employees responded to 2 daily surveys (one at work and one at home) for 5days and a one-time post-study survey. With a total of 810 surveys, hierarchical linear modeling revealed that employees' daily perceived workload positively predicted daily work-family conflict, which in turn negatively predicted daily life satisfaction. Importantly, we found support for a cross-level interaction where supervisor work-family specific support (measured once in the post-study survey) negatively moderated the relationship between daily workload and work-family conflict, attesting the importance of supervisory support in reducing daily interference between work and family.

    Description: ► We considered whether videolinks influence perceived risk. ► A simulated gambling task was used to examine risk. ► People accepted greater risk when collocated. ► Videolinks potentiated perceived risk. In an unregulated environment Internet use is not without risk, and video has been proposed to influence riskiness and trust behaviour. This experiment explored the differences in willingness to take risks on events portrayed over the Internet via a videolink, relative to events occurring in close proximity (collocated). Thirty-four participants played a roulette game on a computer, wagering points upon the outcomes of spins of a real roulette wheel. The amounts, types of bets and the time to place them were analysed. It was found that confidence (points wagered) did not change, but people went for lower risk (when more was at stake), or thought more about the risks they took (when more was at stake) over a videolink. People accepted greater risk on outcomes occurring in close proximity, than those events portrayed over a videolink. Variations in perceived risk in response to online versus offline events probably reflect differences in the potential to influence outcomes.
