The purpose of this study is to identify elements of job crafting impacts on work engagement and individual work performance in Vietnamese commercial banks. The research data, collected from 226 bank officers, uses the quantitative research tools as: Cronbach's Alpha Analysis, Explanatory Factor Analysis, Confirmatory Factor Analysis as well as Structural Equation Modeling. The results of the hypothesis test show that only two hypotheses (H2, H3) are accepted: the impact of cognitive crafting on work engagement of bank officers (H2) and the impact of work engagement on individual work performance (H3). However, three remaining relationships (H1, H4, H5) are not accepted in the study: the impact of relational crafting on work engagement of bank officers (H1), the impact of relational crafting on individual work performance of bank officers (H4) and the impact of cognitive crafting on individual work performance of bank officers (H5). The study results indicate that cognition on job crafting leaves positive impacts on work engagement, leading to individual work performance enhancement. On the other hand, the relational crafting element implies contribution on neither collective nor individual working performances. Furthermore, no direct effect of cognition on job crafting to individual performance has been identified.

Purpose: There is still lack of guidance for merchants toward price discount presentations (absolute/relative), especially for consumers in different purchase contexts. Based on the general evaluability theory, this study investigates consumers' preferences for the presentation of discounts in various contexts through experiments. Research design, data and methodology: The relationship between discount presentation and consumers' preference is investigated in Study 1 using a two-factor between-subject design of 2 (purchase type: material vs. experiential) ×2 (discount type: absolute vs. relative). The Moderating effect of thinking mode has been examined in Study 2 via a multi-factor intergroup design of 2 (purchase type: material vs. experiential) ×2 (discount type: absolute vs. relative) ×2 (cognitive load: high vs. low). One-way ANOVA and planned contrast have been performed for analysis. Results: Experiment 1 reveals that consumers prefer absolute discounts rather than relative discounts when in material purchases. However, when in experiential purchases, they are willing to choose relative discounts. Experiment 2 verifies the boundary conditions of matching effect and illustrates the generation of matching effect is determined by thinking mode. Conclusions: Our study enriches the theories of purchase type and thinking mode. Simultaneously, the results provide practical guidance for merchants to formulate the discount presentation and distribution pricing strategies.

Many psychiatric disorders are associated with brain functional dysfunctions and neuronal degeneration. According to the research so far, enhanced brain plasticity reduces neurodegeneration and recovers neuronal damage. Brain-derived neurotrophic factor (BDNF) is one of the most extensively studied neurotrophins in the mammalian brain that plays major roles in neuronal survival, development, growth, and maintenance of neurons in brain circuits related to emotion and cognitive function. Also, BDNF plays an important role in brain plasticity, influencing dendritic spines in the hippocampus neurogenesis. Changes in neurogenesis and dendritic density can improve psychiatric symptoms and cognitive functions. BDNF has potent effects on brain plasticity through biochemical mechanisms, cellular signal pathways, and epigenetic changes. There are pharmacological and non-pharmacological interventions to increase the expression of BDNF and enhance brain plasticity. Non-pharmacological interventions such as physical exercise, nutritional change, environmental enrichment, and neuromodulation have biological mechanisms that increase the expression of BDNF and brain plasticity. Non-pharmacological interventions are cost-effective and safe ways to improve psychiatric symptoms.

${\beta}$-asarone (BAS) is an active component of Acori graminei rhizoma, a traditional medicine used clinically in treating dementia and chronic stress in Korea. However, the cognitive effects of BAS and its mechanism of action have remained elusive. The purpose of this study was to examine whether BAS improved spatial cognitive impairment induced in rats following chronic corticosterone (CORT) administration. CORT administration (40 mg/kg, i.p., 21 days) resulted in cognitive impairment in the avoidance conditioning test (AAT) and the Morris water maze (MWM) test that was reversed by BAS (200 mg/kg, i.p). Additionally, as assessed by immunohistochemistry and RT-PCR analysis, the administration of BAS significantly alleviated memory-associated decreases in the expression levels of brain-derived neurotrophic factor (BDNF) and cAMP-response element-binding protein (CREB) proteins and mRNAs in the hippocampus. Also, BAS administration significantly restored the expression of Bax and Bcl-2 mRNAs in the hippocampus. Thus, BAS may be an effective therapeutic for learning and memory disturbances, and its neuroprotective effect was mediated, in part, by normalizing the CORT response, resulting in regulation of BDNF and CREB functions and anti-apoptosis in rats.

In this study, we have verified the memory and cognitive enhancing effect of Longanae Arillus, the fruit of Euphoria longana Lamarck, which has been used as a tonic and for the treatment of amnesia, insomnia, and palpitations in oriental medicine. To investigate the effect of Longanae Arillus water extract(LAE) on the memory and cognitive dysfunction, scopolamine (1 mg/kg, i.p.) was injected in C57BL/6 mice and several behavior tests including Y-maze, Morris water-maze, passive avoidance and fear conditioning tests were conducted. Administration of LAE (100 or 200 mg/kg/day, p.o.) effectively improved scopolamine-induced memory impairment and dysfunction. To further determine the possible molecule mechanism of LAE, we have examined the activity and/or mRNA expression of diverse proteins involved in the acetylcholine metabolism. LAE particularly increased the amount of acetylcholine in the cortex which was mediated by suppression of acetylcholine esterase (AchE) activity. In addition, LAE elevated the mRNA expression of muscarinic acetylcholine receptors (mAchRs) without affecting the mRNA levels of choline acetyltransferase (ChAT) and acetylcholine esterase (AchE). In another experiment, LAE effectively inhibited mRNA expression of pro-inflammatory cytokines such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interleukin-$1{\beta}$ (IL1-${\beta}$), which seemed to be mediated by inhibition of upstream transcription factor NF-${\kappa}B$ and extracellular-regulated kinase 1/2 (ERK1/2). These results demonstrate that Longanae Arillus can increase acetylcholine amount the cortex via regulation of AchE activity as well as mAchRs expression and decrease pro-inflammatory responses via inhibition of NF-${\kappa}B$ signaling pathway, thereby having therapeutic potential to improve memory and cognitive deficit in amnesia.

This study presents work-family multiple-role planning by female university students as a new approach to worklife balance. Accordingly, this study examines university years as a key time frame during which students establish their career paths. This study integrates the social cognitive career theory and the planned behavior theory to design and evaluate a model that explains the work-family multiple-role planning process; in addition, it develops an optimal model to predict the intentions of female university students in work-family multiple-role planning. This study has conducted a structural survey with 500 female university students. After inspecting the data, the responses of 435 participants were used in the data analysis (SEM) with SPSS 21.0 and AMOS 21.0. The findings include the following. First, suitability of predictive model presents a satisfying fit. The major factors in this study's model (parental support, subjective norms, attitudes toward multiple-role planning, career decision self-efficacy, and outcome expectations) are verified as direct and indirect predictors of the work-family multiple-role planning intent of female university students. Second, the strongest predictive factor for the work-family multiple-role planning intent is the social environment factor (subjective norms), indicating that the influence of social pressure on intent is relatively large. The predictive model formulated under this study's integrated theoretical framework supplements existing research that focused on attitudes toward multiple-role planning as well as provides a more profound theoretical foundation on which work-family multiple-role planning behaviors can be better understood.
