A comparative study of managerial stress in greater China : the direct and indirect effects of coping strategies and work locus of control
The present study aims at comparing the direct and indirect effects of coping strategies (control and support coping) and work locus of control (externality) on the stress-strain relationships among managers in Greater China (Peopled Republic of China [PRC], Hong Kong, and Taiwan) using the Occupational Stress Indicator (OSI). Self-administered survey method was employed to collect data from 249 (164 males, 85 females) managers in China, 280 (159 males, 120 females, 1 unclassified) managers in Hong Kong, and 347 (191 males, 151 females, 5 unclassified) managers in Taiwan. The direct and indirect effects of control coping, support coping, and locus of control on some stress-strain relationships were demonstrated in the studied samples. The similarities and differences in managerial stress in Greater China were discussed according to economic and socio-cultural variations
Too Good for Your Job? Disentangling the Relationships Between Objective Overqualification, Perceived Overqualification, and Job Dissatisfaction
In the present study, we investigated the relationships between objective overqualification, perceived overqualification, and job satisfaction based on the tenets of P-E fit theory, a commonly-used theoretical framework in the overqualification literature. Specifically, we tested whether employee perceptions of overqualification mediate the relationship between objective overqualification and job dissatisfaction. Results across two studies indicated that objective overqualification and job satisfaction independently predicted perceived overqualification, which contradicts the prevailing view in the literature of unidirectional effects between overqualification and strain outcomes. Study 1 used a cross-sectional survey of recent college graduates to test the overall mediation model. Although the model was supported, the relationship between objective overqualification and job satisfaction was not significant, raising the question of whether the hypothesized predictive relationship between perceived overqualification and job satisfaction is reversed. Study 2 tested directionality in the relationship between perceived overqualification and job satisfaction using a three-wave longitudinal panel design in a sample of full-time university staff employees. Results indicated that job dissatisfaction predicts subsequent perceived overqualification rather than the reverse
Age differences in work adjustment : a study of male and female managerial stress, coping strategies and locus of control in Hong Kong
The present study is a 15 month project which involved data collection from Hong Kong managers at three points to examine mechanisms by which age would relate to work well-being. A total of 634 managers, both male and female, was drawn by random sampling and purposive sampling methods. The results showed that age was negatively related to job strains and quitting intention, and positively related to job satisfaction. Furthermore, older managers reported fewer sources of stress, better control coping, and a more internal work locus of control. Multiple regression analyses suggested that relations of age with job satisfaction and well-being can be attributed to the better coping, greater internality, lower sources of stress, higher organizational level, and longer tenure of older managers, although differences occurred as a function of gender and the specific well-being measure

Starting fresh: a mixed method study of follower job satisfaction, trust, and views of their leaderâs behavior
IntroductionThe leadership literature has been dominated by the study of broad styles rather than the identification of specific key behaviors. To address this deficiency, a mixed method approach was utilized to explore how follower behavioral descriptions of their leaders would relate to potential outcomes of trust in that leader and job satisfaction.MethodsData were collected from 273 hospital direct reports of 44 managers. They were asked to first describe the leadership approach of their managers in their own words, and then complete quantitative measures of the two potential outcomes.ResultsThe qualitative responses were coded into nine leadership behavior themes listed here in order from most to least often mentioned: Kindness, Supportive, Open to Input, Allow Autonomy, Engage with Team, Transparency, Fairness, Professionalism, Hold Accountable. All behavior themes related significantly to trust of the leader, with three themes relating significantly to job satisfaction (Transparency, Fairness, and Professionalism).DiscussionThese results provide a more specific view of leader behavior than does the typical style approach

Signatures of early frailty in the gut microbiota
Background: Frailty is arguably the biggest problem associated with population ageing, and associates with gut microbiome composition in elderly and care-dependent individuals. Here we characterize frailty associations with the gut microbiota in a younger community dwelling population, to identify targets for intervention to encourage healthy ageing. Method: We analysed 16S rRNA gene sequence data derived from faecal samples obtained from 728 female twins. Frailty was quantified using a frailty index (FI). Mixed effects models were used to identify associations with diversity, operational taxonomic units (OTUs) and taxa. OTU associations were replicated in the Eldermet cohort. Phenotypes were correlated with modules of OTUs collapsed by co-occurrence. Results: Frailty negatively associated with alpha diversity of the gut microbiota. Models considering a number of covariates identified 637 OTUs associated with FI. Twenty-two OTU associations were significant independent of alpha diversity. Species more abundant with frailty included Eubacterium dolichum and Eggerthella lenta. A Faecalibacterium prausnitzii OTU was less abundant in frailer individuals, and retained significance in discordant twin analysis. Sixty OTU associations were replicated in the Eldermet cohort. OTU co-occurrence modules had mutually exclusive associations between frailty and alpha diversity. Conclusions: There was a striking negative association between frailty and gut microbiota diversity, underpinned by specific taxonomic associations. Whether these relationships are causal or consequential is unknown. Nevertheless, they represent targets for diagnostic surveillance, or for intervention studies to improve vitality in ageing
Assessing daily energy intake in adult women:validity of a food-recognition mobile application compared to doubly labelled water
Accurate dietary assessment is crucial for nutrition and health research. Traditional methods, such as food records, food frequency questionnaires, and 24-hour dietary recalls (24HR), have limitations, such as the need for trained interviewers, time-consuming procedures, and inaccuracies in estimations. Novel technologies, such as image-based dietary assessment apps, have been developed to overcome these limitations. SNAQ is a novel image-based food-recognition app which, based on computer vision, assesses food type and volume, and provides nutritional information about dietary intake. This cross-sectional observational study aimed to investigate the validity of SNAQ as a dietary assessment tool for measuring energy and macronutrient intake in adult women with normal body weight (n = 30), compared to doubly labeled water (DLW), a reference method for total daily energy expenditure (TDEE). Energy intake was also estimated using a one-day 24HR for direct comparison. BlandâAltman plots, paired difference tests, and Pearsonâs correlation coefficient were used to assess agreement and relationships between the methods. SNAQ showed a slightly higher agreement (bias = â329.6 kcal/day) with DLW for total daily energy intake (TDEI) compared to 24HR (bias = â543.0 kcal/day). While both SNAQ and 24HR tended to underestimate TDEI, only 24HR significantly differed from DLW in this regard (p < 0.001). There was no significant relationship between estimated TDEI and TDEE using SNAQ (R2 = 27%, p = 0.50) or 24HR (R2 = 34%, p = 0.20) and there were no significant differences in energy and macronutrient intake estimates between SNAQ and 24HR (Î = 213.4 kcal/day). In conclusion, these results indicate that SNAQ provides a closer representation of energy intake in adult women with normal body weight than 24HR when compared to DLW, but no relationship was found between the energy estimates of DLW and of the two dietary assessment tools. Further research is needed to determine the clinical relevance and support the implementation of SNAQ in research and clinical settings. Clinical trial registration: This study is registered on ClinicalTrials.gov with the unique identifier NCT04600596 (https://clinicaltrials.gov/ct2/show/NCT04600596).</p
