Health action process approach: promoting physical activity, and fruit and vegetable intake among Australian adults.

Based on the health action process approach (HAPA) this study examined whether changes in social cognition constructs could predict change in physical activity and fruit and vegetable intake for adult participants in My health for life, an Australian health promotion behaviour change program. Variance-based structural equation modelling was used to analyse data obtained from Australian adult program participants (n = 167) at baseline (T1), week 14 (T2), week 26 (T2), and 6-month post-program (T4). Change scores were calculated for the social cognition constructs and behaviour. Changes in action self-efficacy and outcome expectancies positively predicted changes in intentions. Action self-efficacy changes also predicted changes in maintenance self-efficacy which, in turn, mediated the effect of action self-efficacy on recovery self-efficacy and planning. Planning was predicted by changes in intentions and maintenance self-efficacy. Findings support the use of the HAPA model in designing complex health behaviour change interventions to achieve sustained behaviour change.

An explorative study of psychological and social factors impacting littering behavior in Vietnam.

Littering is a worldwide problem and Vietnam is one of the most affected countries. To enact change, not only individual cognitive determinants but also social and natural-, or environment-related variables should be taken into consideration. Although there is a large body of literature researching littering, most researchers do not distinguish the level of these factors. Thus, this research aims to investigate the interactive mechanism of these different level factors influencing the intention of the Vietnamese to stop littering, with the multi-level social-ecological model used to guide model building. The data were collected through a self-reported online questionnaire and the Partial Least Squares Structural Equation Modelling (PLS-SEM) method was employed to examine the proposed conceptual framework. The results indicated that perceived behavioral control and connectedness to nature are the two main factors influencing the Vietnamese people's intention to stop littering. Multi-group analysis results suggested the moderating effects of injunctive and descriptive norms. This research proposed a new conceptual framework and achieved unique insights into littering behavior in Vietnam, which could benefit and guide behavioral change experts, academics, and practitioners to design appropriate marketing strategies/campaigns to reduce littering.

Association between FLT3-ITD and additional chromosomal abnormalities in the prognosis of acute promyelocytic leukemia.

OBJECTIVES: Internal tandem duplications of the Fms-like tyrosine kinase 3 gene (FLT3-ITD) and additional chromosomal abnormalities (ACA) are prognostic factors in patients with acute promyelocytic leukemia (APL). This study aimed to determine the effect of the association between FLT3-ITD and ACA in the prognosis of APL. METHODS: This was a retrospective cohort study including 60 patients with APL treated with all-trans retinoic acid (ATRA) and chemotherapy. Five-year overall survival (OS) and progression-free survival (PFS) were analyzed in patient groups according to the presence of FLT3-ITD and ACA. RESULTS: FLT3-ITD was an independent adverse factor for 5-year PFS, and ACA was an independent adverse factor for 5-year OS. There were significant differences in OS and PFS among the groups: FLT3-ITD-negative without ACA, FLT3-ITD-positive without ACA, FLT3-ITD-negative with ACA, and FLT3-ITD-positive with ACA. The OS times were 52.917, 45.813, 25.375, and 23.417 months, and the PFS times were 48.833, 38.563, 23.250, and 17.333 months, respectively. CONCLUSION: FLT3-ITD and ACA are associated with the poorest OS and PFS outcomes in patients with APL treated with chemotherapy plus ATRA.

Knowledge hiding in organizational crisis: The moderating role of leadership.

The COVID-19 pandemic has caused organizational crises leading to shutdowns, mergers, downsizing or restructuring to minimize survival costs. In such organizational crises, employees tend to experience a loss or lack of resources, and they are more likely to engage in knowledge hiding to maintain their resources and competitive advantage. Knowledge hiding has often caused significant adverse consequences, and the research on knowledge hiding is limited. Drawing upon the Conservation of Resources and Transformational Leadership theories, a conceptual framework was developed to examine knowledge hiding behavior and its antecedents and consequences. We collected data from 281 Vietnamese employees working during the COVID-19 pandemic. Our results show that role conflict, job insecurity, and cynicism positively impact knowledge hiding behavior. Knowledge hiding behavior negatively affects job performance and mediates the antecedents of knowledge hiding on job performance. Transformational leadership moderated the impact of role conflict on knowledge hiding.

Improved solvent extraction procedure and high-performance liquid chromatography-evaporative light-scattering detector method for analysis of polar lipids from dairy materials.

A normal-phase high-performance liquid chromatography-evaporative light-scattering detector method employing dichloromethane, methanol, and acetic acid/triethylamine buffer as the mobile phase was developed for analysis of polar lipids (PLs). This method was applicable for analysis of PLs from both dairy materials and soy lecithin. All of the PLs of interest such as glycolipids, phospholipids, and sphingomyelin were well separated with a total run time of 22.5 min and without necessitating the removal of neutral lipids beforehand. Peak retention times were stable, and the method was reproducible. In this study, a modified method of using solvents for extraction of PLs from dairy matrices was also investigated. The modified method offered higher extraction efficiency, consumed less time, and in some cases saved solvent use.
