Proactive vitality management, goal attainment, and psychological well-being among college students: A weekly diary study.

Student well-being is under renewed scrutiny due to escalating academic stress and mental health concerns among young adults. However, in addition to the measures taken by lecturers, universities, and local governments (top-down approaches), we still know little about how students themselves can take the proactive strategy to manage their well-being (bottom-up approaches). The current study addressed this gap by proposing and examining the beneficial role of proactive vitality management (PVM)-a proactive action aimed at managing physical and mental energy based on personal unique needs and conditions-on student psychological well-being.

Network crafting, goal attainment, and work-to-family facilitation among hotel employees: the mediating roles of positive affect and information exchange.

Background: The hospitality industry is experiencing new developmental opportunities after the coronavirus pandemic, such as the expansion of digital presence, the introduction of wellness offerings to cater to health-conscious guests, and a growing focus on local and sustainable tourism. However, despite these positive changes, we still lack knowledge on how hospitality workers can proactively adjust their work conditions to excel in their professional domain while also flourishing in their family domain. Thus, the current study proposed and examined how network crafting behaviors can have positive effects on hotel employees' work goal attainment and work-to-family facilitation.

Insights into the Edible and Biodegradable Ulvan-Based Films and Coatings for Food Packaging.

Recently, edible films or coatings that are made from algal polysaccharides have become promising candidates for replacing plastic-based packaging materials for food storage due to their non-toxic, biodegradable, biocompatible, and bioactive characteristics. Ulvan, a significant biopolymer with unique functional properties derived from marine green algae, has been extensively used in various sectors. However, there are fewer commercial applications of this sugar in the food packaging industry compared to many other algae-derived polysaccharides, such as alginates, carrageenan, and agar.

Managing the negative impact of workforce diversity: The important roles of inclusive HRM and employee learning-oriented behaviors.

The workforce has become more diverse than it used to be. Although organizations actively capitalize on workforce diversity to enhance team innovation and organizational performance, it is found that workforce diversity also has potential risks, among which interpersonal conflict is the most salient one. However, we still know relatively less about why workforce diversity may link to higher interpersonal conflict and, more importantly, how to mitigate the negative impact of workforce diversity.

A Weekly Diary Study on Playful Study Design, Study Engagement, and Goal Attainment: The Role of Proactive Personality.

Students' learning processes are heavily impeded by the COVID-19 pandemic. Students are experiencing more online learning environment and less face-to-face idea exchange, which may make them feel exhausted and demotivated. Using self-determination and proactivity theories, we propose and examine whether playful study design (PSD)-a proactive study strategy including designing fun and designing competition in learning tasks-is effective in fostering study engagement, which, in turn, improves study goal attainment during the COVID-19 period.

Geographical differentiation of Molixiang table grapes grown in China based on volatile compounds analysis by HS-GC-IMS coupled with PCA and sensory evaluation of the grapes.

In this study, the volatile fingerprints of GC-IMS showed great differences on the volatile profiles of Molixiang grapes collected from three different regions of China, which suggested that aroma of table grapes could be largely impacted by origin areas. Butyl lactate, -2-octenal and -2-pentanol were mainly contained in MLX-A, the grapes sampled from Ningbo, China. High contents of -cymene, styrene and -terpinene were observed in MLX-B grapes sampled from Beizhen, China.

Umami peptides have been widely studied, except for those from Hypsizygus marmoreus. Therefore, the main purpose of this study was to find new umami peptides in it.

Volatile fingerprints of different parts of Chongming saffron (Crocus sativus) flowers by headspace-gas chromatography-ion mobility spectrometry and in vitro bioactive properties of the saffron tepals.

In this work, the volatile fingerprints of different parts of Chongming saffron flowers (stigmas, stamens, and tepals) were analyzed and compared for the first time by headspace-gas chromatography-ion mobility spectrometry. Three different parts of saffron flowers could be clearly distinguished using principal component analysis based on signal intensity data of gas chromatography-ion mobility spectrometry. Therefore, gas chromatography-ion mobility spectrometry coupled with principal component analysis method could be employed as a new method for authentication and quality control of saffron for the reason of frequent addition with stamens and/or tepals as adulterants in saffron.

Stabilization and Dispersion of OSA Starch-Coated Titania Nanoparticles in Kappa-Carrageenan-Based Solution.

Titania is a white pigment used widely in papermaking, paints and cosmetic industries. Dispersion and stabilization of high concentration titania in water-based system remains a great bottleneck in industry nowadays, because aggregation of titania nanoparticles results in severe adverse effects to gloss, opacity, tint strength, color distribution and storage stability of end products. Because kappa-carrageenan (κ-CG) has excellent rheological properties such as emulsification, gelation, stability and so on, it has the ability to form gel and increase the viscosity of aqueous solution.

Elucidation of aroma compounds in passion fruit (Passiflora alata Ait) using a molecular sensory approach.

In this experiment, Guangxi passion fruit was used as the raw material for natural aroma extraction using the spinning cone column (Spinning Cone Column, SCC) technique. In combination with the semi-quantitative method, the aroma characteristics of the raw pulp (raw whole-fruit puree, PU) before SCC processing, residue (Residue, RS) and extract (Extract, EX) after SCC processing, and passion fruit juice (Juice, JU) were evaluated for their aroma characteristics using headspace gas chromatography-mass spectrometry (HS-SPME-GC-MS), gas chromatography-ion mobility spectrometry (GC-IMS), electronic nose, and sensory evaluation. As a result, a total of 110 aroma substances were detected in four samples, and 33, 38, 73, and 28 aroma components were detected from PU, RS, EX, and JU, respectively.

Attention and Prediction-Guided Motion Detection for Low-Contrast Small Moving Targets.

Small target motion detection within complex natural environments is an extremely challenging task for autonomous robots. Surprisingly, the visual systems of insects have evolved to be highly efficient in detecting mates and tracking prey, even though targets occupy as small as a few degrees of their visual fields. The excellent sensitivity to small target motion relies on a class of specialized neurons, called small target motion detectors (STMDs).

Purpose: College students' well-being is important for their self-growth and the whole society. However, we still know relatively little about how college students could proactively, strategically improve their well-being in the leisure context. Following the self-determination theory and proactivity literature, this study examines how and when leisure crafting (ie, a proactive act whereby individuals balance their leisure resources and demands by utilizing their personal abilities and needs) can enhance college students' well-being.

A Time-Delay Feedback Neural Network for Discriminating Small, Fast-Moving Targets in Complex Dynamic Environments.

Discriminating small moving objects within complex visual environments is a significant challenge for autonomous micro-robots that are generally limited in computational power. By exploiting their highly evolved visual systems, flying insects can effectively detect mates and track prey during rapid pursuits, even though the small targets equate to only a few pixels in their visual field. The high degree of sensitivity to small target movement is supported by a class of specialized neurons called small target motion detectors (STMDs).
