Meta-analytic structural equation modeling for exploring workplace friendship, well-being, and organizational commitment.

Workplace friendships, which are informal relationships in the workplace, foster mutual trust, assistance, and emotional support and create a sense of belonging among coworkers. Employees with positive perceptions of their job responsibilities, psychological needs, and work environment experience happiness, satisfaction, and an overall sense of well-being. A heightened sense of well-being in the workplace positively affects employee satisfaction with job tasks and the work environment, reinforcing employees' sense of belonging and organizational commitment. The study proposed and validated a theoretical model, with meta-analytic structural equation modeling employed to conduct quantitative, empirical research on workplace friendships, well-being, and organizational commitment in Taiwan and to analyze correlations between relevant variables. The theoretical model was further validated through structural equation modeling, which yielded favorable goodness of fit in terms of various indicators. The mediating effect of well-being was verified through bootstrapping analysis. Within a 95% confidence interval, the total effect size of workplace friendships on organizational commitment was 0.549, which is the sum of its direct effect (0.255) and indirect effect (0.294). This finding indicates that well-being plays a mediating role in the association between workplace friendships and organizational commitment. The proposed theoretical model in this study is supported. Finally, the research results are discussed, and practical suggestions are provided.

OCTOPUS: operation control system for task optimization and job parallelization via a user-optimal scheduler

The material acceleration platform, empowered by robotics and artificial intelligence, is a transformative approach for expediting material discovery processes across diverse domains. However, the development of an operating system for material acceleration platform faces challenges in simultaneously managing diverse experiments from multiple users. Specifically, when it is utilized by multiple users, the overlapping challenges of experimental modules or devices can lead to inefficiencies in both resource utilization and safety hazards. To overcome these challenges, we present an operation control system for material acceleration platform, namely, OCTOPUS, which is an acronym for operation control system for task optimization and job parallelization via a user-optimal scheduler. OCTOPUS streamlines experiment scheduling and optimizes resource utilization through integrating its interface node, master node and module nodes. Leveraging process modularization and a network protocol, OCTOPUS ensures the homogeneity, scalability, safety and versatility of the platform. In addition, OCTOPUS embodies a user-optimal scheduler. Job parallelization and task optimization techniques mitigate delays and safety hazards within realistic operational environments, while the closed-packing schedule algorithm efficiently executes multiple jobs with minimal resource waste. Copilot of OCTOPUS is developed to promote the reusability of OCTOPUS for potential users with their own sets of lab resources, which substantially simplifies the process of code generation and customization through GPT recommendations and client feedback. This work offers a solution to the challenges encountered within the platform accessed by multiple users, and thereby will facilitate its widespread adoption in material development processes.

Experiences of psychological, social and organisational work environments in occupational health service in Sweden: a cross-sectional survey

BackgroundThe aim of this study was to compare and describe different professionals’ experiences of workplace psychological and social factors in occupational health (OH) organizations in Sweden.MethodsThis cross-sectional study with a descriptive and comparative design included 472 respondents with common professions in the occupational health service (OHS) in Sweden. Data were collected with “The General Nordic Questionnaire for Psychological and Social Factors at Work” (QPSNordic). The professions have been compared pairwise using the Independent Samples Kruskal-Wallis test, adjusted by Bonferroni correction for multiple tests on subscales and single items and these are presented descriptively.ResultsThe experience of the psychological and social work environment on job task measurement level differed between the professionals. Experiences on social and organizational as well as on individual measurement levels are similar between the professionals who perceive them as satisfactory. Out of the 472 respondents, 7% reported that they had seen someone being subjected to harassment and bullying at the workplace during the last six months.ConclusionsThe experience among the professionals differs most in the Job task measurement level. The results indicate that although different OH professionals experience psychological and social factors at work in different ways, their experiences are generally satisfactory even though harassment and bullying do exist. The research about occupational health professionals and their work environment is sparse. Further applied research is needed for the planning and development of occupational health services in Sweden.

Health Risks Due to Co-Exposure to Noise and Respirable Crystalline Silica Among Workers in the Open-Pit Mining Industry—Results of a Preliminary Study

Occupational exposure to carcinogenic respirable crystalline silica and noise requires a deeper understanding and an assessment of the possible health risks caused by their combined action. Data on individual exposure to respirable crystalline silica (RCS) and occupational noise (ON) was collected among 44 open-pit miners. The study group was divided into two groups according to the job tasks performed. The individual exposure, exceeding of maximum admissible concentration/intensity, and predicted hearing thresholds (HTs) (according to ISO 1999:2013) were compared between the groups directly participating in the technological process (group 1; N = 23) and performing auxiliary, supervising, or laboratory activities (group 2; N = 21). All the analysed indices were significantly higher for group 1; therefore, the job category may predict ON and RCS exposure among open-pit miners. A statistically significant relationship (rs = 0.66, p < 0.05) was found between the time-weighted average (TWA) 8 h RCS and individual daily noise exposure levels. Exposure to noise in the course of employment causes the risk of hearing impairment (mean HTs for 2, 3, and 4 kHz > 25 dB) up to 74% and 4.4% (in the case of groups 1 and 2, respectively). Further studies are needed before conclusions concerning the effects of co-exposure to ON and RCS on open-pit miners can be made.

Shifts in task absorption during decision-making episodes

In today’s rapidly evolving technological landscape, this study investigates the impact of new technology on organizational work dynamics. By integrating the Job Demands-Resources theory and the Episodic Process Model, we examine the cognitive mechanisms that influence task performance during decision-making episodes. Our research focuses on episodic job demands and resources, emphasizing the mediating role of task absorption in the relationship between these factors and task performance. Our findings reveal that episodic job resources positively affect task absorption and performance, while job demands moderate the relationship between job resources and task absorption. Employing the Beer Distribution Game alongside neuroscience-based eye-tracking techniques, we analyze visual attention dynamics during decision-making episodes, providing novel insights into the interplay between task absorption and task performance. Theoretically, our study highlights the significance of task absorption in understanding how episodic job resources impact decision-making performance. Practically, our results advocate for the implementation of decision-making-focused skills development through physiological measures such as neurofeedback training programs. This research underscores the importance of individual time management in enhancing task performance, contributing to a nuanced understanding of job resources, job demands, and task absorption in the context of technological transformation.

A longitudinal pre-post study: An evaluation of the Department of the Air Force bundled occupational fall prevention efforts.

Fall injuries are the second leading cause of traumatic injury and death for all US workers and are a leading injury concern for the Department of the Air Force (DAF). Bundled interventions can improve the likelihood of injury reduction, especially in large, heterogeneous working populations. In 2013, the DAF implemented the "Air Force Fall Prevention Focus," a bundled intervention of prevention efforts designed to reduce occupational fall injury events among DAF members. The purpose of this study is to describe the burden and risk factors associated with fall injuries and evaluate the effectiveness of the Fall Prevention Focus in reducing the burden of fall injuries. The National Institute for Occupational Safety and Health (NIOSH) partnered with the US Air Force Safety Center (AFSEC) to examine the impact of the Fall Prevention Focus as a bundled intervention. Injury events included a narrative description of the injury event, demographics, work environment, job tasks, and other structured details. Descriptive statistics and pre-post longitudinal modeling were used to evaluate changes in fall injury rates. The Fall Prevention Focus Implementation (2013-2018) resulted in an annual 10.4% (95% confidence interval [CI]: 8.5%, 12.2%) reduction, and a 6-year cumulative 48.3% (95% CI: 41.4%, 54.3%) reduction in fall injury event rates by 2018. Safety in the DAF involves a comprehensive approach. Documenting the impact of the Fall Prevention Focus may help translate these findings to improve fall prevention efforts in other sectors of the military and high fall-risk industries in the private sector, such as construction.

The Communication Performance Analysis of the In Room Dining Division at Hotel “A” as the Basis for the Formation of Organizational Culture

Communication performance and organizational culture are closely related, in the process an individual's communication performance reflects their organization's culture. Every company has its organizational culture, including Hotel “A," which is one of the 5-star international hotels in Jakarta, also experiencing issues with its organizational culture. This study employs descriptive research with a qualitative approach. The method used in this research is interview with employees from the in-room dining division at Hotel “A”, that is a 2 active members of the organization. The research findings reveal problems in the communication performance at Hotel “A”. For instance, in terms of ritual performance, there is a company culture of working overtime. Additionally, in terms of passion performance, the abundance of job tasks in the in-room dining division diminishes the manager's focus, especially for unexperienced leader in a similar divisions. Social performance shows the existence of factions within the organization but with no significant impact on operations. Political performance manifests as a sense of superiority over certain groups (seniority). Lastly, enculturation performance indicates differences in training between staff levels and daily workers, creating clearer disparities. All of these issues stem from the inadequate communication performance in the in-room dining division at Hotel “A”. If left unaddressed, they may lead to demotivation, a decline in work ethic, and feelings of saturation among employees, ultimately impacting the formation of the company's culture. The researcher suggests that management and Human Resources collaborate to address these issues, fostering open communication and welcoming input to establish positive organizational culture.

Robots, occupations, and worker age: A production-unit analysis of employment

We analyze the impact of robot adoption on employment composition using novel micro data on robot use of German manufacturing plants linked with social security records and data on job tasks. Our task-based model predicts more favorable employment effects for the least routine-task intensive occupations and for young workers, the latter being better at adapting to change. An event-study analysis for robot adoption confirms both predictions. We do not find decreasing employment for any occupational or age group but churning among low-skilled workers rises sharply. We conclude that the displacement effect of robots is occupation-biased but age neutral whereas the reinstatement effect is age-biased and benefits young workers most.

Relational Job Crafting and Task Performance: The Mediating Role of Work Engagement

This study investigates the mediating role of work engagement on the effect of relational job crafting on task performance among employees in the public sector of Ghana. Relational job crafting involves offers significant benefits to public sector employees by enhancing their performance through collaborative engagement. Thus, when employees actively adjust their social work environment, they can reduce (increase) work-related stress (sense of purpose) through fostering stronger relationships, which also improve well-being and performance. The research employed a closed-ended questionnaire and conducted a cross-sectional online survey. The study’s target population consists of 17,163 public sector employees in Cape Coast Metropolis, out of which 456 were randomly selected to complete the survey. The sample size was estimated using the Adam, (2020) approach for selecting samples in a quantitative study. Data collection took place from January to June 2023, and the analysis was conducted utilising the R version of partial least squares structural equation modelling (PLS-SEM). The study revealed an average yet statistically significant influence of relational job crafting on both work engagement and task performance. Thus, relational job crafting had a significant positive effect on work engagement (β = 0.502, p < 0.01) and task performance (β = 0.293, p < 0.01), with work engagement further affecting task performance significantly (β = 0.475, p < 0.01). The significant positive relationship shows that the increase in both relational job crafting and work engagement among Ghanaian public sector employees further improves their performance in the various tasks assigned to them. Also, despite the direct relationship between work engagement and relational job crafting and task performance, it was further revealed that the latter further mediate the relationship among the former and task performance. Thus, it was found that work engagement serves as a complementary partial mediator in the relationship between relational job crafting and task performance (β = 0.238, SE = 0.034, 95% CI = 0.177, 0.309). These findings support the initial hypotheses established for the study. In terms of policy recommendations, this study emphasises the importance of fostering both work engagement and relational crafting to enhance task performance in the Ghanaian public sector. It suggests that employers, including government bodies, directors, and chief executive officers of public institutions, as well as policymakers, including labour unions, should implement measures across various sectors of public services to strengthen employee relations and increase engagement, ultimately enhancing task performance

AI-induced job impact: Complementary or substitution? Empirical insights and sustainable technology considerations

This study utilizes 3,682 full-time workers to examine perceptions of AI-induced job displacement risk and evaluate AI's potential complementary effects on labor. By distinguishing between these variables, the research identifies which worker characteristics and industries are most affected by AI. Employing an extended ordered probit model, the results show that those with higher perceived risks are mainly female, older, and more educated. Workers with frequent internet usage and remote work are more concerned about AI-induced job risks. Sector-wise, entry-level employees perceive the least risk, whereas manufacturing professionals and senior service sector employees are more apprehensive. Contrary to the mainstream assumption that AI causes unemployment, this study identifies a potential complementary effect on job tasks, suggesting that AI can enhance and support human labor rather than replace it. This inference is based on observed worker perceptions and the increased use of AI tools in tasks that complement human skills. Moreover, AI's integration contributes to sustainable practices and entrepreneurial opportunities, enhancing business innovation and environmental efficiency. Workers increasingly view AI as a value-added element in their jobs rather than a threat, particularly in sectors focusing on sustainable development and green technologies.

A Mobile based Decision Support System for Postural Evaluation of Agricultural Activities with Rapid Entire Body Assessment (REBA)

Agriculture is an unorganized sector and it is a very high drudgery prone profession due to the absence of awareness and entry of advanced agricultural technologies. Many farming activities and operations are carried out by farm workers in the agriculture sector, where they are subject to very poor working conditions which can lead to physical and mental stress. Workers in agriculture experience musculoskeletal disorders in various body parts throughout various agricultural operations. These problems are caused by heavy work loads, repetitive movements, uncomfortable postures, prolonged periods of time spent in neutral or unsupported positions and the use of conventional equipment and implements that are not ergonomically built. The ergonomic risk factors present in the workplace can be examined using various evaluation instruments to ascertain the workers abilities and drawbacks. The work-related risks are measured using the scientifically validated posture assessment instruments. Rapid entire body assessment (REBA) is a technique that assess a person’s complete body including wrists, fore arms, elbows, shoulders, neck, trunk, back, legs and knees. It uses a systematic process to find the postural musculoskeletal disorders and risks associated with the job tasks. A mobile application is developed to assess the agricultural activities on the basis of physiological analysis and postural analysis using REBA ergonomics technique. The application evaluates the drudgery involved in the agricultural work by using physical assessment followed by postural ergonomics methods and provide recommendation of correct posture to avoid developing musculoskeletal disorders.

Understanding Musculoskeletal Risks in Retail Workers: An Ergonomic Assessment of Store 24H

Musculoskeletal disorders (MSDs) are prevalent in retail environments, often resulting from repetitive tasks, awkward postures, and prolonged standing. This study examined musculoskeletal discomfort and ergonomic risk factors within the retail environment of convenience stores, focusing on the prevalence of MSDs among employees of Store 24H, Dungun, Terengganu, Malaysia. The assessment began with a job task description, followed by workplace observation and worker input. Utilising a systematic approach, the research integrated two standardized assessment tools; the Cornell Musculoskeletal Questionnaire (CMQ) and the Initial Ergonomic Risk Assessment (ERA) Form Checklist, to identify the discomfort area and ergonomic risk factors associated with job tasks. Three job tasks were identified in the Store 24H environment; operating cash registers, customer service and restocking. The findings indicate a notable prevalence of MSDs associated with the identified high-risk tasks. Repetitive motions, awkward postures, prolonged standing, and forceful exertion were observed as primary ergonomic risk factors for these tasks which contribute to musculoskeletal discomfort in the neck, shoulder, back, hip, and knee. Additionally, forceful exertion and vibration exhibit high risks towards restocking tasks, resulting in restocking as the top contributor towards the MSDs. Hence, the findings highlight the need for advanced ERA and mitigation strategies, including workstation redesign, task rotation, ergonomic training and accessories, to promote employee well-being and reduce the incidence of MSDs among employees of Store 24H. Implementing these measures is essential for promoting the health and well-being of employees, decreasing the occurrence of musculoskeletal disorders, and improving overall safety and productivity in the workplace.

Ergonomic Considerations for Practicing Massage Therapists.

The physical demands and repetitive movements performed by massage therapists during a treatment increase the risk for work-related musculoskeletal disorders. While massage therapy meets the level of heavy physical demand, the ergonomic risk of performing a massage was previously unknown. The Massage Therapy Foundation undertook a job task analysis to be used by educators, employers, and clinicians to create an optimal work environment. Data collected via survey were used to create the protocol for an onsite data collection where massage therapists were evaluated on the ergonomic risk factors by trained ergonomists. The results of the job task analysis found the highest variability in movement when the massage therapist was treating the neck prone, neck supine, and leg prone. When the massage therapists did not change positions during a stroke, there was increased forward flexion of the trunk which increased postural stress on the extensors of the back and neck. Strokes such as effleurage which can span the entire length of the body part had the highest cumulative load, requiring postures that put mild biomechanical stress on the shoulders (90% of the time), neck (70% of the time), and trunk (60% of the time). The forward-bending posture of the massage therapist increases the eccentric demands of the therapist's neck and back musculature, thereby increasing fatigue and leading to an increase in the chance of overuse injury. The job task analysis recommends the massage therapist monitor the duration of application in an unsupported position, take more time between sessions, work in an optimum environment, including correct table height, and have a healthy, active lifestyle to maintain career longevity.

Leveraging social supports to cope with sales complexities and facilitate value-based selling in the cross-functional sales team contexts: JD-R perspective

In today's dynamic industrial market, adoption of a value-based selling (VBS) has emerged as a crucial approach, which forces companies to establish cross-functional sales teams. Yet how sales task and team complexities, as challenging/hindrance job demands, require team social supports, as job resources, to buffer against them in implementing VBS, remains an under-researched topic. Based on job demands-resources (JD-R) model, we investigate how sales task and sales team complexities moderate the link between social supports and VBS. Findings reveal that, as challenge job demands, demand ambiguity and task non-routineness positively moderate the instrumental/emotional support–VBS link and the instrumental support–VBS link, respectively. Whereas, as hindrance job demands, team instability negatively moderates the instrumental/emotional support-VBS link, and role ambiguity negatively moderates the instrumental support-VBS link. Additionally, team heterogeneity positively moderates the instrumental support-VBS link while negatively moderates the emotional support-VBS link. The study considers the roles of social supports (job resources) in shaping team VBS behavior under different sales complexities (job demands), not only contributing to the VBS literature by extending the research context to B2B cross-functional sales teams, also providing a insights on how to implement VBS and enhance performance via social supports in various sales situational complexities.

The analysis of public service motivation's influence on job enjoyment and task performance in health workers

This study is aimed at determining whether there is an influence of public service motivation on the performance of health workers' duties, the influence of work pleasure on the work pleasure of health employees, and the influence on work pleasure through the mediation of work satisfaction. The study is in the form of an observational causative study with a cross sectional design, which aims to determine the influence between variables based on measurement results without intervention. The data were collected through an online questionnaire in April 2024 and analyzed using the PLS-SEM technique to estimate the degree of relationship between variables in the structural model. The results of the analysis of the measurement component (outer model) shows good measurability of all indicators marked by outer loading which is high, as well as the validity of discrimination is quite good. The model has a good degree of accuracy because it is able to account for about two-thirds of all variables. For the management of the hospital, it is recommended to add the criteria of high publicly service motivation as a requirement in employee recruitment. Further research is suggested to complement the model by including factors such as work environment, organizational culture, workload, and superior leadership style as covariates. This could help in identifying unique challenges or opportunities for improving task performance and job satisfaction in different healthcare environments, ultimately leading to more tailored and effective management strategies.

Einstein's combinatory play: A promising practice for creativity and well-being among public health professionals

The purpose of this commentary is to describe combinatory play as a practice for elevating creativity and well-being among public health professionals. Albert Einstein introduced combinatory play in a letter to a colleague, and, in this commentary, we define it as engagement in an intrinsically enjoyable, cognitively stimulating artistic activity that is distinct from one's job tasks and conducive to connecting ideas toward insight and creative problem-solving. Combinatory play aligns with empirical and experiential evidence demonstrating connections between art and science. We present combinatory play in the context of research on creativity and well-being, including the growing issue of work-related stress among public health professionals. To provide an example of combinatory play, we recount how Robert Frost's poem “Mending Wall” inspired email blackout periods and an intervention for health researchers. Finally, we outline concrete strategies for public health professionals to integrate combinatory play into their lives. Overall, combinatory play is a promising practice for catalyzing novel solutions to public health issues while fueling the well-being of public health professionals themselves.

An End-User Evaluation of Blast Overpressure and Accelerative Impact Body-Worn Sensors.

Blast overpressure and accelerative impact can produce concussive-like symptoms in service members serving both garrison and deployed environments. In an effort to measure, document, and improve the response to these overpressure and impact events, the U.S. Army Medical Material Development Activity is evaluating body-worn sensors for use by the Joint Conventional Force. In support, the WRAIR completed a qualitative end-user evaluation with service members from high-risk mission occupational specialties to determine the potential needs, benefits, and challenges associated with adopting body-worn sensors into their job duties. WRAIR staff led hour-long semi-structured focus groups with 156 Army, Navy, and Marine Corps participants, primarily representing infantry, combat engineer, explosive ordnance disposal, artillery, mortar, and armor job specialties. Topics included their sensor needs, concepts of operations, and recommended design features for implementing sensors into the force. Dialogue from each focus group was audio recorded and resulting transcripts were coded for thematic qualitative analysis using NVivo software. Users recommended a single, unobtrusive, rugged, multi-directional sensor that could be securely mounted to the helmet and powered by a battery type (such as rechargeable lithium or disposable alkaline batteries) that was best suited for their garrison and field/deployed environments. The sensors should accurately measure low-level (∼1.0 pounds per square inch) blasts and maintain a record of cumulative exposures for each service member. Discussions supported the need for immediate, actionable feedback from the sensor with the option to view detailed blast or impact data on a computer. There were, however, divergent opinions on security issues regarding wireless versus wired data transfer methods. Participants also expressed a need for the exposure data to integrate with their medical records and were also willing to have their data shared with leadership, although opinions differed on the level of echelon and if the data should be identifiable. Regarding accountability, users did not want to be held fiscally liable for the sensors and recommended having the unit be responsible for maintenance and distribution. Concerns about being held fiscally liable, being overly burdened, and having one's career negatively impacted were listed as factors that could decrease usage. Finally, participants highlighted the importance of understanding the purpose and function of the sensors and supported a corresponding training module. Participating service members were generally willing to adopt body-worn sensors into their garrison and deployed activities. To maximize adoption of the devices, they should be convenient to use and should not interfere with service members' job tasks. Providing a clear understanding of the benefits (such as incorporating exposure data into medical records) and the function of sensors will be critical for encouraging buy-in among users and leaders. Incorporating end-user requirements and considering the benefits and challenges highlighted by end users are important for the design and implementation of body-worn sensors to mitigate the risks of blast overpressure and accelerative impact on service members' health.

Job crafting and work engagement: A study of civil service bureau employees in the Kingdom of Bahrain

This study examined the impact of job crafting on work engagement among Bahraini Civil Service Bureau employees. A survey was used to collect data from 278 participants resulting in a 93.3% response rate. The findings showed that increasing structural job resources, decreasing hindering job demands and increasing challenging job demands had a positive and statistically significant impact on work engagement. However, there was no significant relationship found between increasing social job resources and work engagement. Reducing hindering job demands was identified as the most influential dimension followed by increasing structural job resources and increasing challenging job demands. The study recommended encouraging employees to consult their superiors, providing more flexibility in job task execution and motivating participation in new programs. These findings contribute to understanding the relationship between job crafting and work engagement offering practical implications for enhancing employee engagement and well-being in the Civil Service Bureau.
