This study explores the role of artificial intelligence (AI) in human resource management (HRM), with a focus on recruitment, employee retention, and performance optimization. Through a PRISMA-based systematic literature review, the paper examines many machine learning algorithms including XGBoost, SVM, random forest, and linear regression in decision-making related to employee-attrition prediction and talent management. The findings suggest that these technologies can automate HR processes, reduce bias, and personalize employee experiences. However, the implementation of AI in HRM also presents challenges, including data privacy concerns, algorithmic bias, and organizational resistance. To address these obstacles, the study highlights the importance of adopting ethical AI frameworks, ensuring transparency in decision-making, and developing effective integration strategies. Future research should focus on improving explainability, minimizing algorithmic bias, and promoting fairness in AI-driven HR practices. Full article

Introduction: Poorly designed safety job descriptions may have a negative impact on occupational safety and health (OSH) performance. Firstly, they limit the chances of hiring highly qualified safety professionals who are vital to the success of OSH management systems in organizations. Secondly, the relationship between the presence of qualified safety professionals and the safety culture (and performance) in an organization is reciprocal. Thirdly, the low quality of job descriptions limits exploring the proper competencies needed by safety professionals before they are hired. The safety professional is thus uncertain of what level of education or training and which skills they should attain. Objectives: The main goal of the study is to integrate the analytic hierarchy process (AHP) and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) with importance–performance analysis (IPA) to evaluate job descriptions in multiple sectors. Results: The results of the study indicate that it is vital to clearly define job levels, the overall mission, key responsibilities, time-consuming tasks, required education/certifications, and necessary personal abilities in safety job descriptions. This clarity enhances recruitment, fairness, performance management, and succession planning. The organization can then attract and retain top talent, improve performance, foster a strong safety culture, create realistic job expectations, increase employee satisfaction and productivity, and ensure that competent individuals are hired, ultimately leading to a safer and more productive workplace. Conclusion: The outcomes of this study provide a robust framework that can and should be used as a guideline to professionalize job description development and enhance talent acquisition strategies.

This study examines how several gender-encoding strategies in Spanish and social factors influence gender perception, reinforcing or mitigating a sexist male bias. Using an experimental design, we tested four linguistic conditions in a job recruitment context: masculine forms (theoretically generic), gender-splits, epicenes, and non-binary neomorpheme “-e”. After reading a profile in one of these conditions, 837 participants (52% women) selected an image of a woman or man. Results show that masculine forms lead to the lowest selection of female candidates, manifesting a male bias. In contrast, gender-fair language (GFL) strategies, particularly the neomorpheme (les candidates), elicited the highest selection of female images. Importantly, not only did linguistic factors and participants’ gender identity influence results—with male participants selecting significantly more men in the masculine condition, but affinity with feminist movements and LGBTQIA+ communities or positive attitudes towards GFL also modulated responses—increasing female selections in GFL, but reinforcing male selections in the masculine. Additionally, no extra cognitive cost was found for GFL strategies compared to masculine expressions. These findings highlight the importance, not only of linguistic forms, but of social and attitudinal factors in shaping gender perception, with implications for reducing gender biases in language use and broader efforts toward social equity.

Background/Objectives: This study aimed to examine the occurrence and risk factors for proximal junctional kyphosis (PJK) in relation to preoperative sagittal alignment, particularly the shape of thoracolumbar kyphosis (TLK) and the proportion of lumbar lordosis. Methods: We recruited 38 consecutive patients with adolescent idiopathic scoliosis (AIS) who underwent isolated posterior fusion. Participants were categorized according to the presence or absence of PJK at 1 year postoperatively (PJK+ or non-PJK) and by preoperative TLK status (positive or negative; pre-TLK+ or pre-TLK, respectively). We compared spinal parameters preoperatively, immediately postoperatively, and at 1 year postoperatively between groups. Results: Among the 38 participants, PJK occurred in 21 patients (55.3%). The PJK group had significantly larger preoperative TLK and LDI values and decreased postoperative TLK and LDI. Simple linear regression revealed a moderate positive correlation between ΔPJA and preoperative TLK as well as a fair positive correlation between ΔPJA and changes in TLK and LDI. The prevalence of PJK was high (83.3%) in the pre-TLK+ group (24 patients), and preoperative LDI was significantly larger compared with the pre-TLK group. However, TLK and LDI were significantly decreased after surgery in the pre-TLK+ group. Conclusions: Patients with Lenke-5C curvature who exhibit positive preoperative TLK are at a very high risk of developing PJK after isolated posterior surgery. Preoperative sagittal alignment should be considered when planning the extent of sagittal correction. Full article

Objectives/Background: With increasing awareness of the association between physical activity and mental health, promoting youth health has gained prominence. For this, education and support are needed. As psychological school-based factors could be key to affecting this behavior, this study investigates middle school students’ trust in their physical education teachers and their grit, analyzing their effects on health-promoting behaviors that could follow these adolescents through adulthood. Methods: Middle school students, aged 12–14, were recruited from three schools in Sejong City, Korea, in May 2025; 420 survey questionnaires were distributed and 390 were returned (response rate: 92.86%). After eliminating those with insincere responses, 369 valid questionnaires (boys = 186, girls = 183) were analyzed. The analysis covered the descriptive statistics, Pearson’s correlation, and structural equation modeling, with grit, trust in physical education teachers, and health-promoting behaviors as variables. Results: The correlation analysis verified multicollinearity between trust in physical education teachers (closeness, fairness, teaching method, and physical ability), grit (effort, perseverance, and interest consistency), and health-promoting behaviors (self-actualization, health management, and stress management). A positive significant correlation was found between all subfactors (p < 0.05). The research model’s fit was confirmed through several fit indices; specifically, normed χ² = 4.138, goodness-of-fit-index = 0.942, root mean square residual = 0.033, root mean square error of approximation = 0.092, incremental fit index = 0.965, Tucker–Lewis index = 0.947, and comparative fit index = 0.965, and all values were judged acceptable. The standardized coefficients of each latent variable explaining the measurement variables were 0.707 or higher. Therefore, the explanatory power of the measurement variables was also satisfactory; thus, the research model was appropriate and could be used for analysis. The model findings revealed that trust in physical education teachers had a positive effect on student grit (β = 0.505, p < 0.001) and that grit had a positive effect on health-promoting behaviors (β = 0.743, p < 0.001); however, trust in physical education teachers did not have a direct effect on health-promoting behaviors (statistically insignificant [β = 0.103, p > 0.05]). Thus, grit had a mediating effect between trust in physical education teachers and health-promoting behaviors (β = 0.375, p < 0.01). Conclusions: This study highlights the educational implications for physical education teachers of building trust and strengthening student grit as key factors in achieving sustainable health-promoting behaviors among adolescents.

Background/Objectives: Currently, Oman lacks a valid culture-specific food frequency questionnaire (FFQ) for adults. This research aimed to develop and validate a reliable (FFQ) specifically for Omani adults. The study was conducted in two phases, employing both qualitative and quantitative methods. Phase 1 was the development of the (FFQ); in this phase the Diet History Questionnaire II (DHQ II) was adapted to develop the Omani Food Frequency Questionnaire (OFFQ), translated to the Arabic language, back-translated to English, pilot tested, and then refined to be used in the reliability study. Phase 2 was the reliability study, in this phase, the OFFQ was administered twice in Arabic with the second being filled one to two weeks after the first questionnaire. Methods: A convenience sample of healthy Omani adults (n = 62) was recruited from Sultan Qaboos University (SQU) employees and students. To assess the reliability of the OFFQ both internal consistency and test–retest reliability were assessed. Internal consistency was assessed by conducting Cronbach’s α test, while test–retest reliability was assessed by comparing the median intake of food groups by calculating weighted kappa (K_W) and intraclass correlation coefficients (ICCs). Results: Weighted kappa (K_W) between the two OFFQ administrations showed fair to moderate agreement with (K_W) values ranging from 0.38 to 0.60 for questions assessing the frequency of intake. While the median (K_W) values between the two OFFQ administrations ranged from 0.26 to 0.58 for questions assessing portion size. The majority of food groups showed moderate to good test–retest reliability with median (ICCs) for food groups ranging from 0.57 to 0.80 for frequency questions and from 0.40 to 0.82 for portion questions. Conclusions: In conclusion, the newly developed OFFQ was deemed valid for the Omani dietary culture and is a reliable tool that can measure habitual dietary intake among Omani adults as evidenced by the reliability coefficients ranging from moderate to good agreement for the most food items and food groups. Future studies are warranted to assess the relative validity of the OFFQ and the inclusion of diverse demographic groups and a larger sample size. Full article

Smartphone-embedded inertia sensors are widely available nowadays. We have developed a smartphone application that could assess temporal gait characteristics using the built-in inertia measurement unit with the aim of enabling mass screening for gait abnormality. This study aimed to examine the test–retest reliability and concurrent validity of the smartphone-based gait assessment in assessing temporal gait parameters in level-ground walking. Twenty-six healthy young adults (mean age: 20.8 ± 0.7) were recruited. Participants walked at their comfortable pace on a 10 m pathway repetitively in two walking sessions. Gait data were simultaneously collected by the smartphone application and a VICON system during the walk. Gait events of heel strike and toes off were detected from the sensors signal by a peak detection algorithm. Further gait parameters were calculated and compared between the two systems. Pearson Product–Moment Correlation was used to evaluate the concurrent validity of both systems. Test–retest reliability was examined by the intraclass correlation coefficients (ICCs) between measurements from two sessions scheduled one to four weeks apart. The validity of smartphone-based gait assessment was moderate to excellent for parameters involving only heel strike detection (r = 0.628–0.977), poor to moderate for parameters involving detection of both heel strike and toes off (r = 0.098–0.704), and poor for the proportion of gait phases within a gait cycle. Reliability was good to fair for heel strike-related parameters (ICC = 0.845–0.388), good to moderate for heel strike and toes-off-related parameters (ICC = 0.827–0.582), and moderate to fair for proportional parameters. Validity was adversely affected when toe off was involved in the calculation, when there was an insufficient number of effective steps taken, or when calculating sub-phases with short duration. The use of smartphone-based gait assessment is recommended in calculating step time and stride time, and we suggest collecting no less than 100 steps per leg during clinical application for better validity and reliability.

All beta- and gamma-herpesviruses utilize a set of six viral proteins to facilitate transcription from specific promoters that become active late in the viral life cycle. These proteins form a complex that interacts with a TA-rich sequence upstream of the late transcription start sites and recruits RNA polymerase II (Pol II). The structure of any of the late transcription factors (LTFs) alone or in complexes has not been solved by standard means yet, but a fair amount is known about how the proteins interact and where the complex is positioned over the late promoters. Here, AlphaFold3 was used to predict and analyze the LTF complex using proteins from the beta-herpesviruses HCMV, MCMV, HHV6, and HHV7, and from the gamma-herpesviruses EBV and KSHV. The predicted structures had high levels of confidence and were remarkably similar even though there is little sequence conservation in the LTFs across the viruses. The results are consistent with most of the previously determined information concerning the interaction of the factors with each other and with DNA. A conserved threonine phosphorylation in one of the subunits that is critical to the function of the LTFs is predicted to be at the junction of five subunits. AlphaFold 3 predicts seven metal ion binding sites in each of the four beta-herpesviruses and either five or six in the gamma-herpesviruses created by conserved residues in three of the subunits. The structures also provide insights into the function of the subunits and which host general transcription factors (GTFs) may or may not be utilized during initiation. Full article

Background: Continuous vital sign monitoring using wearable sensors has gained traction for the early detection of patient deterioration, particularly with the advent of virtual wards. Objective: The objective was to evaluate the reliability of a wearable sensor for monitoring heart rate (HR), respiratory rate (RR), and temperature in acutely unwell hospital patients and to identify the optimal time window for alert generation. Methods: A prospective cohort study recruited 500 patients in a single hospital. Sensor readings were compared to standard intermittent nurse observations using Bland–Altman plots to assess the limits of agreement. Results: HR demonstrated good agreement with nurse observations (intraclass correlation coefficient [ICC] = 0.66, r = 0.86, p < 0.001), with a mean difference of 3.63 bpm (95% LoA: −10.87 to 18.14 bpm). RR exhibited weaker agreement (ICC = 0.20, r = 0.18, p < 0.001), with a mean difference of −2.72 breaths per minute (95% LoA: −10.91 to 5.47 bpm). Temperature showed poor to fair agreement (ICC = 0.30, r = 0.39, p < 0.001), with a mean difference of −0.57 °C (95% LoA: −1.72 to 0.58 °C). A 10 min averaging window was identified as optimal, balancing data retention and real-time alerting. Conclusions: Wearable sensors demonstrate potential for reliable continuous monitoring of vital signs, supporting their future integration into real-world clinical practice for improved patient safety.

The objective of this study is to explore the relationships among four key attributes—nutritional value, attitude, repurchase intention, and price fairness—in the context of the cereal product market. Additionally, the research investigates the moderating effect of price fairness on the relationship between nutritional value and consumer attitude using the low involvement theory as a theoretical underpinning. The study utilized the Clickworker platform to recruit 414 survey participants using an online survey, whose responses were analyzed using Hayes’ Process Macro Model 7. The findings reveal that nutritional value positively affects both consumer attitude and repurchase intention. Moreover, a significant positive relationship between attitude and repurchase intention was found. Importantly, price fairness was found to significantly moderate the relationship between nutritional value and consumer attitude, highlighting the role of perceived fairness in shaping consumer behavior. This research contributes to the literature by examining these relationships in the specific context of cereal products. Full article

Background: Dysphonia, a common symptom after thyroid surgery, is most often caused by damage to the recurrent laryngeal nerve. Laryngeal electromyography (LEMG) is used as a qualitative diagnostic tool to distinguish neurological etiology from other causes of dysphonia. The purpose of this study is to establish the value of LEMG as a predictor factor in the recovery of unilateral recurrent paralysis post-thyroidectomy. Methods: This study included 11 patients with unilateral vocal fold palsy (UVFP) evidenced on the videostrobolaryngoscopy (VSL) after thyroidectomy. Electrical activity of thyroarytenoid (TA) muscles of the patients included in the study was recorded through LEMG and the prognosis of the lesions was classified as excellent, fair, or poor based on the presence of spontaneous activity and motor unit recruitment. Results: LEMG at the first clinic visit showed an excellent prognosis in three of the cases, a fair prognosis in three of the cases, and five of them indicated a poor prognosis. At 6 months after the first LEMG, patients with a poor prognosis were unchanged and showed no LEMG improvement. Those with an excellent prognosis showed an increased recruitment response, and LEMG was normal. In one patient with a fair prognosis and minimal spontaneous activity, LEMG recruitment decreased during reevaluation. The other two fair-prognosis patients had a normal LEMG. Conclusions: A correlation was found between LEMG findings and functional recovery of the vocal cords, demonstrating that the presence of spontaneous activity represents a negative prognostic factor. However, due to limited patient cohorts, the sensitivity of the LEMG as a prognostic tool in the functional recovery of the larynx is not yet established and requires further research. Full article

Background/Objectives: Shift work is prevalent among nurses, often leading to adverse psychological effects, such as fatigue, depression, anxiety, and stress. Understanding how shift work contributes to psychological health disorders can help healthcare organizations identify critical areas where support should be offered. This study aimed to determine the relationships between shift work, psychological health disorders, and job security among nurses in Saudi Arabia. Methods: This cross-sectional study included 163 nurses, recruited via convenience sampling. The participants completed an online questionnaire that assessed demographic variables, psychological disorders, fatigue, and job security. The data were analyzed using descriptive statistics as well as bivariate analyses to explore relationships between variables. Results: Most participants (73%) worked 12 h shifts, and 67.5% reported fair sleep quality. We found significant correlations among shift work, fatigue, and common psychological disorders. Significant differences were also observed for fatigue (p = 0.007) and depression (p = 0.008). Both nationality (p < 0.001) and shift work (p = 0.015) were correlated with anxiety. Similarly, significant differences were found for nationality (p = 0.001) and shift work (p = 0.002) regarding stress. Conclusions: These findings underscore the psychological challenges faced by nurses related to shift work, emphasizing the importance of addressing fatigue and mental health. Healthcare organizations should implement strategies to enhance job security and support nurses’ well-being to ultimately improve both nurse satisfaction and patient care outcomes. Further research is warranted to explore effective interventions and the long-term effects of shiftwork on nursing professionals. Full article

Background/Objectives: The aim of this study is to assess the inter- and intra-observer reproducibility of the identification of direct and indirect ultrasonographic features of adenomyosis as defined by the revised Morphological Uterus Sonographic Assessment (MUSA) consensus (2022). Methods: A cohort of 74 women, aged 18 to 45, were recruited from the recurrent miscarriage and general gynaecology clinic at a university-based fertility centre. All the participants underwent 2D and 3D transvaginal Ultrasound scan (TVS) examination in the late follicular and early luteal phase. Conventional grey scale and power Doppler image volumes were acquired and stored. Subsequently, the stored 3D ultrasound images were independently re-evaluated offline by the two observers for the direct and indirect features of adenomyosis as outlined by the revised MUSA group. The intra- and the inter-observer reproducibility was estimated using Cohen’s Kappa coefficient. Results: The intra- and interobserver reproducibility (K −0.27, 95% CI 0.06–0.48 and K 0.13, 95% CI −0.10–0.37, respectively) for at least one direct feature of adenomyosis was only modest. Amongst the individual direct features, the interobserver variability of identifying myometrial cysts was fair (K 0.21, 95% CI −0.00–0.42), whereas the intra-observer variability was moderate (K 0.44, 95% CI 0.26–0.63). While hyperechogenic islands identification achieved a fair level of intra- (K 0.31, 95% CI 0.09–0.53) and interobserver (K 0.24, 95% CI 0.01–0.47) agreement, the reproducibility of reporting sub-endometrial lines/buds was fair for the intra-observer (K 0.22, 95% CI −0.02 0.47) and poor for the interobserver (K 0.00, 95% CI −0.20–0.19). The interobserver agreement for indirect features varied from poor to moderate, while the intra-observer agreement ranged between poor to good. Conclusions: The reporting of adenomyosis using direct features suggested by the revised MUSA group consensus showed only modest interobserver and intra-observer agreement. The definitions of ultrasound features for adenomyosis need further refining to enhance the reliability of diagnosis criteria of adenomyosis. Full article

The undergraduate college years are a critical transition period for young adults in establishing life-long health behaviors. Background/Objective: Within the FRESH Study, we aimed to understand the relationship between perceived physical health, perceived mental health, and specific health metrics (e.g., physical activity, food insecurity, sleep quality) among college students following the COVID-19 pandemic. Methods: First-year undergraduate students (n = 271) from an urban university were recruited in three study waves (2021–2022, 2022–2023, and 2023–2024). Participants answered online surveys on demographics, health perceptions, physical activity, dietary patterns, beverage consumption, food insecurity, stress, and sleep quality. Results: Overall, participants rated their physical health better than their mental health (‘good’, ‘very good’, or ‘excellent’; 89.6% vs. 62.2%), even though 30.7% were not of ‘healthy weight’ status, 34.5% did not meet physical activity recommendations, and 42.2% of students consumed some sugar-sweetened beverages (SSBs). Students reporting suboptimal (‘fair’ or ‘poor’) physical and mental health were more likely to report food insecurity (p < 0.001, p = 0.010), poor sleep quality (p = 0.012, p < 0.001), and elevated stress (p = 0.001, p < 0.001). In addition, fast-food consumption (p < 0.001), breakfast consumption (p = 0.031), and food insecurity (p = 0.004) showed changes over three years. Conclusions: These findings call for targeted wellness initiatives addressing nutrition, food insecurity, stress management, sleep improvement, and physical activity among students and in university health programs. The FRESH Study emphasizes the need for continued longitudinal research to track health behaviors and inform future interventions. Full article

Building employee loyalty is a prerequisite for a company to achieve a competitive advantage, high organizational performance, and sustainability. The lack of voluntary leaves does not result in recruitment costs or reduced efficiency during the adaptation period of a new employee. It helps retain knowledge and experience within the organization. The article aims to explore employees’ loyalty in terms of voluntary employment continuity during the pandemic slowdown of COVID-19, when employee loyalty was put to an exceptional test, and identify the factors that have had the most significant impact. This empirical study was carried out for Germany, mainly due to the strength and position of the German economy in Europe and the availability of a large, detailed micro dataset necessary for in-depth econometric analyses. The dataset used in the survey is the fifth wave of the German Linked Personnel Panel—LPP in 2020/21 (N = 7397). A multinomial logit model was used as a research tool. Loyalty appears as an explained variable in four ordered logit models that differ in the set of explanatory variables. The explanatory variables include demographics, job title, working conditions, compensation and rewards, job content, training and career development, teamwork, and relationships with colleagues and superiors. The results confirm the influence of extra-organizational factors, such as age and living in a four- or five-person household, on employee loyalty. However, age seems to be a factor of decreasing importance. Too much complexity of work, manifested by great task variety, working in multiple teams, and the requirement to perform work remotely, harmed employee loyalty during the pandemic. Findings justify building loyalty based on sustainable human resource policies to increase income satisfaction, reasonable workload, competence development, and greater autonomy at work. It is also clear that leadership issues (fairness in contact with superiors and recognition for work) mattered during this challenging time and have a high potential to improve employee loyalty in the future.
