This study aims to explore psychological safety as a potential moderating mechanism for the relation between functional diversity and individual perceptions of learning, and functional diversity and team performance in self-assembled teams.

To test these relationships, the authors conducted a cross-level, time-lagged, quasi-experiment, using a sample of 143 self-assembled teams. In one condition, participants formed into functionally diverse teams, and in another condition, participants formed functionally homogeneous teams.

Results suggest that functional diversity and psychological safety have an interactive effect on both individual learning and self-assembled team performance, albeit in different directions. Specifically, low psychological safety was more deleterious for individuals on functionally diverse teams than functionally homogeneous teams when it came to perceptions of learning, but the opposite was true when it came to team performance.

The results of this study indicate that it is critical to train team members on developing psychological safety, both in traditional and functionally diverse contexts.

This study aimed to evaluate the compositional changes and bioaccessibility of phenolics and antioxidants in propolis during in vitro digestion as well as the cytotoxic effects of digested propolis on various cancer cell lines.

Six propolis samples were obtained and subjected to in vitro oral, gastric and intestinal digestion. Both digested and undigested samples were analyzed for their total phenolic, flavonoid and antioxidant activities. Additionally, changes in phenolic composition in the in vitro digestion system were revealed by the HPLC-DAD system. The cytotoxic effects of the digested samples were assessed on lung (A549, H1299), skin (A431), liver (Hep-G2) and colon (Caco-2) cancer cells as well as on fibroblast (Bj) cells.

The mean bioaccessibility values of phenolic and flavonoid compounds were found to be less than 35 and 24%, respectively, while the TEAC and CUPRAC antioxidant results ranged between 225.08–649.04 and 398.68–1552.28 µmol TE/g, respectively. The release of p-coumaric, ferulic, 3,4-dimethoxycinnamic acids, naringenin, pinocembrin and chrysin increased progressively from the oral to the intestinal stage. The cytotoxic effects of samples on cell lines were ranked, based on IC50 results, as A431 > Hep-G2 > Caco-2 > A549 > H1299 > Bj.

Propolis has been recognized for centuries as a natural remedy, and numerous studies have explored its bioactive components. However, no studies have previously examined the changes in the phenolic compositions of propolis samples during digestion or their cytotoxic effects on cancer cells. Therefore, this study provides novel insights and an approach to the existing literature on this topic.

Safety-related issues are prominent in dyeing workplaces and studios that result in accidents. The purpose of this study is to investigate the compliance towards health safety practices by students at the dyeing studios in selected universities in Ghana.

A structured online questionnaire was developed and used to collect 285 responses from students studying at the textile and fashion department of ten universities in Ghana. The study used the partial least square (PLS) algorithm of the structural equational modelling (SEM) by bootstrapping with 5,000 samples in the SmartPLS-SEM version 4.0.

Students exhibited good attitudes with significant knowledge regarding health safety hazards at the dyeing studio. Results revealed that students’ attitudes significantly and positively affect their knowledge of health safety hazards; hence, as attitude increases, their knowledge of health safety hazards also increases. However, institutional support significantly and negatively affects the knowledge of health safety hazards by students at the dyeing studio. Subsequently, institutional support significantly and positively affects students’ attitudes towards health safety hazards at the dyeing studio; hence, as institutional support increases, their attitude towards health safety hazards also increases. In the moderation analysis, results showed that students’ attitude dampens the negative relationship between institutional support and student’s knowledge.

Work-related safety at the dyeing studios is very important to help drive for an injurious free hands-on practice with dyeing activities. Hence, the findings of this study call on institutions to provide appropriate personal protective equipments and first aid kits, effective training and supervision for workspace safety at the dyeing studios for students. This would go a long way to maintain good health safety practices during students’ dyeing activities at the studio, hence eliminating possible hazards.

The present study provides an in-depth understanding of how key variables such as institutional support influence the knowledge and attitude of students towards studio dyeing practices. Key findings from the study reiterated the importance of training workshops, state-of-the-art studios and adherence to safety by students to prevent injuries.

The production of commodities from renewable organic material has gained enormous interest due to the rising public understanding of conscious development. Natural fibers are accessible in environment, and their parameters depend on their physical traits and chemically engineered makeup. Grewia optiva (GO) comes under the category of bast fibers, also known as Bhimal. This study aims to realize the consequences of alkali treatment on the characterization of natural fibers, their developed yarn and then the woven mat.

Raw fiber was treated with 20% alkali solution. After treatment, it was evaluated for changes in the general laboratory system. This treatment is known as mercerization, through which the parameters of cellulose fibers can be enhanced. After this process, the content of cellulose increases due to the removal of the hydroxyl group. The removal of microfibrils, hemicellulose and the introduction of hydrogen bonds increase the interactive capacity of fiber. The job was divided into different sections, including acquiring fiber, developing yarn and creating a mat.

The quality of the surface of the fiber was enhanced after the treatment. Its diameter was reduced to 54.72 microns. In the developed woven mat, it was densified using water treatment and attained grams per square meter (GSM) of 389.7.

The usage of mercerization softens the fiber to twist into yarn, which is finally woven into a mat. Treatment of fabric or mat makes it denser to impart better strength. A woven mat of natural fibers provides maximum strength to the composites.

The purpose of this study is to assess a novel method for creating tangible three-dimensional (3D) morphologies (scaled models) of neuronal reconstructions and to evaluate its cost-effectiveness, accessibility and applicability through a classroom survey. The study addresses the challenge of accurately representing intricate and diverse dendritic structures of neurons in scaled models for educational purposes.

The method involves converting neuronal reconstructions from the NeuromorphoVis repository into 3D-printable mold files. An operator prints these molds using a consumer-grade desktop 3D printer with water-soluble polyvinyl alcohol filament. The molds are then filled with casting materials like polyurethane or silicone rubber, before the mold is dissolved. We tested our method on various neuron morphologies, assessing the method’s effectiveness, labor, processing times and costs. Additionally, university biology students compared our 3D-printed neuron models with commercially produced counterparts through a survey, evaluating them based on their direct experience with both models.

An operator can produce a neuron morphology’s initial 3D replica in about an hour of labor, excluding a one- to three-day curing period, while subsequent copies require around 30 min each. Our method provides an affordable approach to crafting tangible 3D neuron representations, presenting a viable alternative to direct 3D printing with varied material options ensuring both flexibility and durability. The created models accurately replicate the fidelity and intricacy of original computer aided design (CAD) files, making them ideal for tactile use in neuroscience education.

The development of data processing and cost-effective casting method for this application is novel. Compared to a previous study, this method leverages lower-cost fused filament fabrication 3D printing to create accurate physical 3D representations of neurons. By using readily available materials and a consumer-grade 3D printer, the research addresses the high cost associated with alternative direct 3D printing techniques to produce such intricate and robust models. Furthermore, the paper demonstrates the practicality of these 3D neuron models for educational purposes, making a valuable contribution to the field of neuroscience education.

Although sexual identity disclosure in the workplace can be related to heightened adversity for lesbian, gay or bisexual (LGB) employees, disclosure can also serve as an avenue for LGB employees to attain additional resources. Much of the work done in today’s organizations is done in team-based structures, making it likely that LGB individuals disclose to members of their work teams. However, very limited prior research has examined the associations of sexual identity disclosure within work team experiences. This paper aims to take a first step in addressing this gap in research on the experiences of LGB employees in the workplace.

This study takes a first step toward addressing this gap by examining the associations between LGB identity disclosure and critical team-specific attitudes and behaviors (i.e., trust in team, commitment to team, conflict with team, withdrawal from team) and the atemporal indirect role of perceived LGB identity support from the team through a cross-sectional survey of 159 employees.

Results demonstrated that perceptions of a supportive LGB team climate atemporally mediated the association between disclosure and relevant workplace variables. Specifically, disclosure of sexual identity to one’s work team is directly and indirectly, through perceived identity support, positively associated with trust and commitment toward the team. Furthermore, disclosure was indirectly, through perceived identity support, negatively associated with conflict and withdrawal from the team. Theoretical and practical implications of these findings are discussed.

The results of this study highlight the importance of perceived identity support when individuals disclosure their sexual orientation in a team context.

There is an emerging interest in understanding the cognitive, emotional and motivational processes that drive tourists' behaviour using neuroscientific research methods. This chapter briefly reviews the main methods of interest to tourism researchers, to then focuses on electroencephalography, which reflects electrical activity from the brain. Event-related potentials or electroencephalography oscillations reflect cognitive and affective processes. Components of the former can index emotional brain responses, and alpha oscillations are related to attention and approach/withdrawal. Existing tourism literature/using electroencephalography are reviewed. This is a promising tool for studying a range of phenomena that are of interest to tourism scholars, but require careful use of methods and interpretation.

Polyurethane (PUR) foam parts are traditionally manufactured using metallic molds, an unsuitable approach for prototyping purposes. Thus, rapid tooling of disposable molds using fused filament fabrication (FFF) with polylactic acid (PLA) and glycol-modified polyethylene terephthalate (PETG) is proposed as an economical, simpler and faster solution compared to traditional metallic molds or three-dimensional (3D) printing with other difficult-to-print thermoplastics, which are prone to shrinkage and delamination (acrylonitrile butadiene styrene, polypropilene-PP) or high-cost due to both material and printing equipment expenses (PEEK, polyamides or polycarbonate-PC). The purpose of this study has been to evaluate the ease of release of PUR foam on these materials in combination with release agents to facilitate the mulding/demoulding process.

PETG, PLA and hardenable polylactic acid (PLA 3D870) have been evaluated as mold materials in combination with aqueous and solvent-based release agents within a full design of experiments by three consecutive molding/demolding cycles.

PLA 3D870 has shown the best demoldability. A mold expressly designed to manufacture a foam cushion has been printed and the prototyping has been successfully achieved. The demolding of the part has been easier using a solvent-based release agent, meanwhile the quality has been better when using a water-based one.

The combination of PLA 3D870 and FFF, along with solvent-free water-based release agents, presents a compelling low-cost and eco-friendly alternative to traditional metallic molds and other 3D printing thermoplastics. This innovative approach serves as a viable option for rapid tooling in PUR foam molding.

This case study is based on primary data collected through interviews with the company’s founder and CEO. It also includes secondary data collected through the Glassdoor job search and career community site. The names of the company and the employees have been disguised. However, the figures included accurately represent the primary data and the quotes are directly from the company representative.

When it was founded in 2009, employees were excited about the prospect of working at Wombat alongside its founder and CEO Dan Wallace. They had looked forward to making a difference in the lives of college students with the company’s higher ed-focused digital communication platform. But by 2022, Wallace could not ignore the significant change in these employees’ attitudes. Anonymous feedback pointed to employees’ commitment to Wombat having wavered, and employees’ reception of post-COVID organizational changes had become concerningly critical. Though he knew enough to be concerned, Wallace felt unsure of how to move forward based on the anonymous feedback alone. He was left wondering: how should Wombat communicate with employees to boost their attitudes and strengthen their commitment while making the hard decisions that best serve the company?

This case study is appropriate for upper-level undergraduate and graduate students in organizational communication courses. It can constitute the employee communication module in a class that surveys strategic managerial communication, or it could be used as one of many examples in a course specifically focused on the internal communication component of the discipline. Students will need an understanding of communication theory, specifically interpretive organizational communication theory, to grasp the complexities of the case. While the focus company is in the educational technology industry, the themes presented are faced by companies of all sizes in all sectors.

Steam explosions are a major safety concern in many modern furnaces. The explosions are sometimes caused by water ingress into the furnace from leaks in its high-pressure (HP) cooling water system, coming into contact with molten matte. To address such safety issues related to steam explosions, risk based inspection (RBI) is suggested in this paper. RBI is presently one of the best-practice methodologies to provide an inspection schedule and ensure the mechanical integrity of pressure vessels. The application of RBIs on furnace HP cooling systems in this work is performed by incorporating the proportional hazards model (PHM) with the RBI approach; the PHM uses real-time condition data to allow dynamic decision-making on inspection and maintenance planning.

To accomplish this, a case study is presented that applies an HP cooling system data with moisture and cumulated feed rate as covariates or condition indicators to compute the probability of failure and the consequence of failure (CoF), which is modelled based on the boiling liquid-expanding vapour explosion (BLEVE) theory.

The benefit of this approach is that the risk assessment introduces real-time condition data in addition to time-based failure information to allow improved dynamic decision-making for inspection and maintenance planning of the HP cooling system. The work presented here comprises the application of the newly proposed methodology in the context of pressure vessels, considering the important challenge of possible explosion accidents due to BLEVE as the CoF calculations.

This paper however aims to optimise the inspection schedule on the HP cooling system, by incorporating PHM into the RBI methodology, as was recently proposed in the literature by Lelo et al. (2022). Moisture and cumulated feed rate are used as covariate. At the end, risk mitigation policy is suggested.

In this paper, the proposed methodology yields a dynamically calculated quantified risk, which emphasised the imperative for mitigating the risk, as well as presents a number of mitigation options, to quantifiably affect such mitigation.
