Cultural differences in indecisiveness: the role of naïve dialecticism

East Asians exhibit naïve dialecticism, a set of worldviews that tolerates contradictions. As influenced by naïve dialecticism, East Asians are more likely to hold and less likely to change ambivalent attitudes, compared with European North Americans. If East Asians have a heightened tendency to see both positive and negative aspects of an object or issue, but a lesser inclination to resolve these inconsistencies, East Asians (vs. European North Americans) may experience more difficulty in committing to an action, and thus be more indecisive. Consistent with this hypothesis, we found that East Asian Canadians scored higher on a measure of chronic indecisiveness than did European Canadians and South Asian Canadians, and that naïve dialecticism and need for cognition mediated the relationship between culture and indecisiveness. These results add to the extant literature on indecisiveness, demonstrating cultural variations in indecisiveness and an underlying cultural factor that is responsible for these cultural differences

Culture moderates the pliability of ambivalent attitudes

Ambivalent attitudes are comprised of conflicting components. In response to this evaluative conflict, North Americans are more likely to change high ambivalent attitudes than low ambivalent attitudes. However, East Asians exhibit greater tolerance for inconsistencies than do North Americans. Hence, we hypothesized that culture would interact with ambivalence in influencing the degree of attitude change in response to a persuasive attempt. Results indicated that culture significantly moderated the relationship between ambivalence and attitude pliability, such that ambivalence and the degree of attitude change were positively associated for European Canadians but not for East Asian Canadians. These results add to the extant literature on attitudinal ambivalence, demonstrating cultural variability in the pliability of ambivalent attitudes

Culture and state boredom: A comparison between European Canadians and Chinese

The primary goal of the present research was to examine cross-cultural validity of the Multidimensional State Boredom Scale (MSBS) by comparing a European Canadian sample and a Chinese sample. The secondary goal was to explore cross-cultural differences in the actual experience of boredom between European Canadian and Chinese participants when they completed a psychological survey. After establishing cross-cultural validity of the MSBS by eliminating items that functioned differentially across the two cultural groups, we found that European Canadians scored higher on the MSBS than did Chinese. Results are consistent with the literature on cultural differences in ideal affect, such that European North Americans (vs. East Asians) tend to value high-arousal positive affects (e.g., excitement) more, and low-arousal positive affect less (Tsai, Knutson, & Fung, 2006)

How robust is the own-group face recognition bias? Evidence from first- and second-generation East Asian Canadians

There is mounting evidence that North Americans are better able to remember faces of targets who belong to the same social group, and this is true even when the social groups are experimentally created. Yet, how Western cultural contexts afford the development of this own group face recognition bias remains unknown. This question is particularly important given that recent findings suggest that first-generation East Asian Canadians do not show this bias. In the current research, we examined the own-group bias among first- and second-generation East Asian Canadians, who vary systematically in their exposure to and engagement in a Western cultural context, and tested mediators that could explain any difference. In Study 1, second-generation East Asian Canadians showed better memory for same-group (vs. other-group) faces. In Studies 2 and 3, as well as a meta-analysis of all three studies, we found some additional evidence that second-generation East Asian Canadians show better memory for same-group (vs. other-group) faces, whereas first-generation East Asian Canadians do not, but only when each cultural group was examined separately in each study, as no interaction with generational status emerged. In Study 2, and in a higher powered pre-registered Study 3, we also examined whether second- (vs. first-) generational status had a positive indirect effect on same-group face recognition through the effects of acculturation and perceived relational mobility in the immediate social environment, however this mediation model was not supported by the data. Overall, the results provide some additional evidence that the effect of mere social categorization on face recognition may not be as consistently found among East Asian participants

Does self-construal shape automatic social attention?

We examined whether activating independent or interdependent self-construal modulates attention shifting in response to group gaze cues. European Canadians (Study 1) and East Asian Canadians (Study 2) primed with independence vs. interdependence completed a multi-gaze cueing task with a central face gazing left or right, flanked by multiple background faces that either matched or mismatched the direction of the foreground gaze. Results showed that European Canadians (Study 1) mostly ignored background gaze cues and were uninfluenced by the self-construal primes. However, East Asian Canadians (Study 2), who have cultural backgrounds relevant to both independence and interdependence, showed different attention patterns by prime: those primed with interdependence were more distracted by mismatched (vs. matched) background gaze cues, whereas there was no change for those primed with independence. These findings suggest activating an interdependent self-construal modulates social attention mechanisms to attend broadly, but only for those who may find these representations meaningful

Home-based lifestyle intervention for rural adults improves metabolic syndrome parameters and cardiovascular risk factors: A randomised controlled trial.

The presence of metabolic syndrome (MetS) increases the risk of developing type 2 diabetes and cardiovascular disease. Targeted interventions to reduce MetS for high risk populations are crucial for the prevention of these chronic diseases. This study evaluated the effectiveness of a 6-month home-based physical activity and diet intervention for rural adults with, or at risk of MetS. The randomised controlled trial was conducted in Albany and surrounding towns, Western Australia, 2014–2015. Participants were screened for MetS using the International Diabetes Federation criteria, and eligible participants were randomly assigned to the intervention (n = 201) or control (n = 200) group. The intervention group received printed and online programme materials and motivational support, and the control group was waitlisted to receive the programme after post-test data collection. Anthropometry, lipid profiles, glycaemic status, and blood pressure were measured at baseline and 6-months post-test. In total, 312 (77.8%) participants completed post-test data collection and were included in the anthropometric analysis, and 274 (68.3%) participants were included in the blood sample analysis.After controlling for confounders, the intervention group significantly improved their triglyceride (− 0.10 mM, p = 0.002), total cholesterol (− 0.09 mM, p = 0.02), and non-HDL cholesterol (− 0.08 mM, p = 0.02) concentrations compared to the control group. Waist circumference (− 2.11 cm, p = 0.03), waist-to-hip ratio (− 0.01, p = 0.04), weight (− 0.70 kg, p = 0.01), and body mass index (− 0.20 kg/m2, p < 0.001) were also improved. These findings suggest that comprehensive home-based prevention programmes that include a combination of dietary and physical activity interventions are a promising means to prevent the onset of chronic disease in rural adults

Microarray Analysis in the Archaeon Halobacterium salinarum Strain R1

Background: Phototrophy of the extremely halophilic archaeon Halobacterium salinarum was explored for decades. The research was mainly focused on the expression of bacteriorhodopsin and its functional properties. In contrast, less is known about genome wide transcriptional changes and their impact on the physiological adaptation to phototrophy. The tool of choice to record transcriptional profiles is the DNA microarray technique. However, the technique is still rarely used for transcriptome analysis in archaea. Methodology/Principal Findings: We developed a whole-genome DNA microarray based on our sequence data of the Hbt. salinarum strain R1 genome. The potential of our tool is exemplified by the comparison of cells growing under aerobic and phototrophic conditions, respectively. We processed the raw fluorescence data by several stringent filtering steps and a subsequent MAANOVA analysis. The study revealed a lot of transcriptional differences between the two cell states. We found that the transcriptional changes were relatively weak, though significant. Finally, the DNA microarray data were independently verified by a real-time PCR analysis. Conclusion/Significance: This is the first DNA microarray analysis of Hbt. salinarum cells that were actually grown under phototrophic conditions. By comparing the transcriptomics data with current knowledge we could show that our DNA microarray tool is well applicable for transcriptome analysis in the extremely halophilic archaeon Hbt. salinarum. The reliability of our tool is based on both the high-quality array of DNA probes and the stringent data handling including MAANOVA analysis. Among the regulated genes more than 50% had unknown functions. This underlines the fact that haloarchaeal phototrophy is still far away from being completely understood. Hence, the data recorded in this study will be subject to future systems biology analysis

Effects of a home-based intervention on diet and physical activity behaviours for rural adults with or at risk of metabolic syndrome: a randomised controlled trial

BACKGROUND: This study aimed to determine whether a home-based 6-month lifestyle intervention program complemented by motivational interviewing could improve diet and physical activity behaviours in 50-69 year olds with or at risk of metabolic syndrome, residing in a disadvantaged rural Western Australian community. METHODS: Participants from the City of Albany and surrounding towns (n?=?401) were recruited into a 6 month randomised controlled trial. They were screened for metabolic syndrome and randomly allocated to intervention (n?=?201) or control group (n?=?200). Baseline and post-test data collection for both groups included a self-report questionnaire which incorporated the Fat and Fibre Barometer and the International Physical Activity Questionnaire Short Form. The intervention group received the program materials at baseline and the control group was waitlisted. Generalised estimating equation models assessed repeated outcome measures over time. RESULTS: A total of 151 (75.1 %) intervention and 159 (79.5 %) control group participants completed post-test and were included in the analysis. After controlling for confounders, the intervention group achieved a marginally significant increase in their metabolic equivalent (MET) minutes of moderate intensity physical activity per week (p?=?0.049), and significantly improved fibre intake (p?&lt;?0.001), fat intake (p?=?0.003), and vegetable serves per day (p?=?0.002) from baseline to post-test relative to the control group. CONCLUSION: A home-based, low-cost intervention with motivational support can effectively improve the physical activity and dietary behaviours of adults aged 50-69 years with or at risk of metabolic syndrome residing in a disadvantaged rural area.
