Quiet quitting has attracted growing attention as a form of work withdrawal, yet evidence from vocational education remains limited. Drawing on Conservation of Resources theory, this study examines how person-organization fit, work-family conflict, and work overload relate to quiet quitting among vocational college lecturers, with job burnout as a mediator. A cross-sectional online survey was conducted among vocational college lecturers in China, and 523 valid responses were analyzed using partial least squares structural equation modeling. Person-organization fit negatively predicted quiet quitting and job burnout, whereas work-family conflict positively predicted both outcomes. Work overload did not directly predict quiet quitting but showed an indirect effect through job burnout. Job burnout significantly predicted quiet quitting and mediated the relationships between the three antecedent variables and quiet quitting. These findings extend Conservation of Resources theory by showing that quiet quitting among vocational college lecturers is shaped by multi-level stressors and operates largely through job burnout, highlighting the importance of improving person-organization fit, reducing work-family conflict, and managing workload to sustain lecturer engagement.
Quiet quitting is reported to be on the increase in the post-COVID pandemic workplace, especially among early-career Generation Z (Gen Z) employees. This trend poses serious challenges and could negatively affect organisational productivity, performance, and profitability. The purpose of this study is to evaluate the effects of mentoring and coaching on quiet quitting among graduate interns. This study also seeks to assess whether work engagement mediates this relationship and job insecurity moderates the mediated relationship between mentoring and coaching and quiet quitting via work engagement. Purposive and snowball sampling were used to recruit participants. Data were collected from 264 graduate interns employed in fixed-term internship programmes in South African organisations. The data was analysed using the SPSS PROCESS macro and SPSS Amos 30 graphics. The results showed that mentoring and coaching was significantly and negatively related to quiet quitting behaviours among graduate interns, and this negative relationship was partially mediated by work engagement. Furthermore, job insecurity moderated the mediated effect of mentoring and coaching on quiet quitting behaviours via work engagement. This study advances our understanding of how organisations can mitigate quiet quitting among graduate interns by integrating the social exchange theory and Job Demands-Resources model (JD-R). The practical implication for organisations is to capacitate line managers with technical, professional, and interpersonal skills to mentor and coach early-career Gen Z employees. Line manager mentoring and coaching will increase early-career Gen Z employees' work engagement and subdue quiet quitting, which is reported to be on the rise among this generation.
Evidence for a bilateral cochlear implant (BiCI) advantage in quiet is inconsistent, in part because many studies compare binaural versus acutely monaural conditions within BiCI users, which cannot model long-term unilateral (UniCI) adaptation. The authors asked whether BiCI confers a measurable benefit over UniCI for speech perception in quiet after rigorously controlling selection bias, and which patient factors modulate this benefit. Single-center retrospective cohort of 184 postlingually deafened adults (109 UniCI, 75 BiCI) implanted between February 2013 and March 2025. The authors performed 1:1 propensity-score matching (PSM) using age, sex (exact match), and principal component composites of preoperative audiology to yield 120 patients (60 UniCI, 60 BiCI) with excellent balance. Speech perception in quiet (mono-, di-syllable, sentence) was assessed at 3, 6, and 12 months after activation. Longitudinal trajectories were analyzed with linear mixed-effects models, with cumulative auditory experience (Average Daily Device Use × Months Post-Activation) modeled via restricted cubic splines. Prespecified interactions tested effect modification by sex, age group (20 to 50 versus 50 to 70), cumulative use, and preoperative performance. Sensitivity analyses used a stricter PSM caliper (0.1). Before matching, BiCI recipients-despite poorer baselines-improved more steeply and achieved higher scores across time points. After PSM, BiCI showed a significant main effect for monosyllabic word recognition (β = 12.70, p = 0.005), with parallel results under stricter matching (β = 13.53, p = 0.005). Cumulative auditory experience strongly predicted improvement (both spline terms p < 0.001), but there was no significant Group × Cumulative-use interaction, indicating comparable use-performance slopes in BiCI and UniCI. Thus, the BiCI advantage cannot be attributed to greater device use. A significant Preoperative Score × Sex interaction (β = 14.49, p = 0.021) indicated that higher preoperative performance was more prognostic in males than females; this effect was specific to monosyllables. Disyllables showed a smaller yet significant BiCI effect; sentences trended in the same direction. Age group (20 to 50 versus 50 to 70) did not significantly modify the BiCI effect, and combining age groups was required to detect statistical significance, consistent with an age-independent bilateral benefit. In a rigorously matched cohort with longitudinal modeling, BiCI yielded a robust advantage over UniCI for quiet monosyllabic recognition that persisted after controlling for behavioral and demographic confounders. The absence of a Group × Use interaction and the pattern restricted to low-context tasks support an interpretation most consistent with neurophysiological mechanisms (e.g., binaural summation, interaural-timing integration, cortical-level plasticity), rather than motivational or selection-related artifacts. Because this advantage was not significantly modified by age, the data suggest that bilateral stimulation offers broadly preserved benefits across adult age ranges. These findings provide clinically actionable evidence to inform counseling and strengthen policy discussions on expanding adult coverage from unilateral to bilateral implantation under public insurance frameworks. Larger, prospective cohorts with mechanistic endpoints remain essential to confirm durability, generalizability, and neural underpinnings.
This study investigates the underlying psychosocial mechanisms of quiet quitting among teachers by examining the relationships between psychological well-being, dark leadership, and organizational cynicism within an integrated structural model. The study is based on data obtained from a sample of 555 teachers in Turkey. Grounded in the Conservation of Resources Theory and Social Exchange Theory, the study proposes that teachers' psychological well-being serves as a protective personal resource, mitigating negative organizational experiences and shaping behavioral outcomes. The results reveal that psychological well-being is negatively associated with quiet quitting both directly and indirectly through dark leadership and organizational cynicism. Teachers with higher levels of well-being tend to report lower perceptions of dark leadership, display lower cynicism, and report reduced withdrawal tendencies. Furthermore, the findings indicate that dark leadership is positively associated with organizational cynicism, which in turn strongly predicts quiet quitting. The serial mediation analysis demonstrates that psychological well-being is associated with quiet quitting through a sequential pathway of dark leadership and organizational cynicism, highlighting the multilayered nature of withdrawal behaviors in educational settings. Overall, the study contributes to the literature by integrating individual, interpersonal, and organizational factors into a comprehensive framework and offers practical implications for fostering supportive leadership practices, strengthening teacher well-being, and reducing disengagement in schools.
While parenthood is gratifying, it is also a significant life transition, filled with challenges and stressors that require ongoing psychological and behavioral adjustments. This study aims to: (1) verify the psychometric characteristics of the Perceived Corporate Welfare Scale (PCWS), and (2), in line with the Job Demands-Resources (JD-R) theory, investigate how corporate welfare and parenting self-regulation act as resources against perceived stress and quiet quitting. We further explored the mediating role of stress and the moderating effect of parenthood. A group of 788 Italian workers (43.5% non-parents; 29.6% moms; 26.9% dads) participated. The psychometric properties of the PCWS were tested using CFA. A moderated mediation model was estimated using Bootstrap methods (95% CI). The PCWS showed a robust one-factor structure with significant item loadings (>0.60) and satisfactory reliability (CR and AVE). Findings suggest that perceived corporate welfare and parenting self-regulation function as resources and are negatively associated with perceived stress. Perceived stress fully mediates the relationship between perceived corporate welfare and quiet quitting and partially mediates the relationship between parenting self-regulation and quiet quitting. Crucially, parenthood moderates this relationship: fathers' perceived stress has a stronger association with quiet quitting than mothers' does. Consequently, the indirect effects are also stronger for fathers. This study provides a validated tool for monitoring perceptions of corporate welfare. The results suggest that personalized interventions and an organizational culture that values parenthood are key to sustaining well-being and long-term employee engagement.
Assess the impact of different stance variations, body composition and use of shoes among healthy young men and women on postural sway during quiet stance. A repeated-measures study with 123 participants (40 males, 83 females) aged 18-39 years was conducted. Participants stood quietly without shoes on a force plate with hands on hips (also performed with shoes), hands by sides, arms across chest, hands behind head and while isometrically contracting. Postural sway metrics were assessed for each condition. Body composition was assessed using bioelectric impedance analysis. There were no significant differences found between stances involving hands on hips, arms across chest, hands behind head, or hands by sides in the measured variables. Postural sway was greatest during isometric contraction (p < 0.05). Women had greater path length, sway frequency and greater anterior-posterior sample entropy (AP SampEn) compared to men (p < 0.05). Quiet stance postural sway was not influenced by the use of shoes. Variables related to lean body mass are significantly associated with postural sway as assessed by principal component analysis. The assessment of quiet standing postural control in healthy young adults can use a variety of stance variations (with or without shoes) since they yield statistically similar measures of postural sway. Postural sway is significantly increased with muscle contraction. Young women exhibit greater path length, sway frequency and AP SampEn compared to young men. Lean body mass may represent a target for improved postural control since it is associated with postural sway.
Intensifying geopolitical and organizational pressures have amplified psychosocial risks in healthcare, particularly in the context of persistent nursing shortages. These conditions can enable covert managerial behaviors such as quiet firing, which undermine nurse wellbeing and threaten workforce stability. Given the limited empirical evidence, a validated instrument is essential to detect such early risks and inform organizational prevention strategies. A Chinese version of the Quiet Firing Scale was developed through translation, back-translation, and cross-cultural adaptation. Using purposive sampling, nurses from five general hospitals were surveyed to assess the scale's reliability and validity. Of 782 returned questionnaires, 720 were deemed valid and included in the psychometric validation. The Chinese version comprised 7 items and demonstrated a unidimensional structure, explaining 67.36% of the total variance in exploratory factor analysis. Item-level content validity indices (I-CVI) ranged from 0.820 to 1.000, with a scale-level CVI of 0.905. Confirmatory factor analysis supported a well-fitting model (CFI = 0.991, GFI = 0.980, NFI = 0.984, IFI = 0.991, TLI = 0.983, RMSEA = 0.060). Convergent validity was confirmed by an Average Variance Extracted of 0.591 and Composite Reliability of 0.894. The scale exhibited strong internal consistency (Cronbach's α = 0.908), split-half reliability (0.939), and test-retest reliability (0.899). The Chinese version of the Quiet Firing Scale is a psychometrically robust tool for assessing nurses' experiences in general hospitals. It establishes a foundation for examining its prevalence and potential effects on nurse wellbeing and workforce stability.
The neural encoding of voicing in speech sounds has been relatively well studied in monolingual, native speakers. Little research, however, has examined neural encoding of aspiration feature in speech sounds or focused on encoding of non-native phonetic features or the effect of noise on processing these features. This study examined Auditory Evoked Potentials (AEPs) to bilabial stops with English versus Hindi phonetic properties of aspiration and voicing Hindi, English and Tamil listeners, in quiet and in noise. A total of 48 participants (16 Hindi, 16 American English, and 16 native Tamil native speakers) between 20 and 45 years of age participated. Natural digitized speech sounds including Hindi /ba/, /pa/, and /pha/ and American English /ba/, and /pa/ were presented at 70 dB SPL using insert earphones in quiet, and in background noise at signal-to-noise ratio of 0. AEP peaks P1, N1, P2, and N2 were measured at the central electrode site (FCz). The P1 and P2 peak amplitudes were significantly larger for Hindi CV stimuli in Hindi participants relative to American English participants and Tamil participants. The morphology to Hindi /pha/ was similar to English /pa/, and the morphology for Hindi /pa/ was similar to English /ba/. P1 amplitudes were larger and P2 amplitudes were smaller in noise relative to quiet. N2 peak latency in response to Hindi /pa/ was slightly longer relative to Hindi /pha/ in American English listeners. The findings add evidence to the Automatic Speech Perception model by observing cross-linguistic differences in P1 and P2. The results contribute to a better understanding of neural encoding in the cortex across native and non-native listeners, and how noise modulates early stages of processing.
Postural stability during quiet human stance relies heavily on neural feedback control. However, delays in this feedback can markedly reshape closed-loop dynamics and potentially compromise balance stability. Despite this, from a theoretical perspective, the mechanisms by which such delays affect balance stability remain poorly understood. Most existing studies rely on numerical simulations of neuromechanical models of human standing, while rigorous mathematical analysis of the system's dynamic properties is still lacking. To address this gap, this study proposed a frequency-domain analytical framework based on a widely adopted neuromechanical model of human postural control. By transforming the postural control system into the complex frequency domain, we derived analytical solutions and systematically investigated how the system's characteristic roots in the Laplace domain evolved with increasing neural feedback delay. This analysis revealed the mechanisms by which delays induce instability. Furthermore, we derived critical conditions for system destabilization and provided an exact analytical expression for the delay threshold leading to instability. Based on these results, a stability criterion was proposed, providing a theoretical basis for assessing the robustness of postural control. The proposed framework applies to the study of postural stability in populations such as older adults and patients with neurodegenerative diseases. Over all, this research provides a solid theoretical foundation, both qualitative and quantitative, for understanding instability in human postural control induced by varying neural feedback delays.
Risky, high-stimulant supplement use and IPED-like products are increasingly common in recreational fitness environments and represent a relevant public health and harm-reduction concern. While psychosocial correlates of such decisions have been widely examined, less is known about visuocognitive processes involved in the real-time evaluation of supplement-related information at the point of choice. Quiet Eye (QE), defined as the final fixation before an action, has been described as a marker of attentional stability but has not yet been examined in the context of supplement-related risk decision-making. A laboratory eye-tracking study was conducted with 166 recreational fitness athletes. Participants viewed a standardized supplement stimulus containing reward-related and warning-related cues, completed a binary task-based risky-choice task, and reported their intention to use the risky product. Measures of QE fixation duration, psychosocial risk constructs, and experimentally induced cognitive load were obtained. Logistic and linear regression models were estimated using standardized predictors. Longer QE fixation on warning cues was associated with a lower likelihood of selecting the risky supplement (OR = 0.50, p = 0.003) and with lower intention scores (b = -4.20, p < 0.001). In standardized terms, a one-SD increase in QE_warning corresponded to an approximately 50% reduction in the odds of choosing the risky option and a decrease of about four points on the 0-100 intention scale. QE fixation on reward cues was associated with intention but not with task-based choice. Psychosocial variables showed consistent associations with both outcomes: risk acceptance was positively associated with intention and risky choice, whereas risk perception was inversely associated with both. Cognitive load was associated with higher intention scores (b = 2.02, p = 0.002) but was not associated with task-based choice. The findings indicate that warning-related QE fixation is associated with lower intention and a reduced likelihood of risky choice in supplement-related decisions. QE metrics are interpreted as visuocognitive markers of attentional allocation during the final phase of decision-making rather than as causal determinants. Together with established psychosocial correlates, visuocognitive attention may constitute an additional descriptive component in understanding supplement-related risk decision processes, with potential relevance for harm-reduction approaches in visually dense fitness environments.

Surgical specialties continue to be dominated by men, even though women make up more than 50% of medical school graduates. Female surgeons' self-esteem, career paths, and well-being are destroyed by overt discrimination and microaggressions, which also have an impact on team dynamics and patient safety. Women in surgery report widespread bias, from being mistaken as nurses to receiving fewer highly complex cases, which contributes to emotional burnout, obstructed skill-learning, and premature career termination. The hidden "time taxes" of additional planning and self-monitoring, which go beyond the typical obstacles, reduce output and limit creativity. We support structured mentorship programs, clear criteria for case allocation and promotion, clear leadership commitment to gender parity in the operating room, and institution-wide implicit bias training as ways to break these long-standing trends.
This study aimed to compare posturographic measures between acute low back pain patients (LBP) and healthy controls. A total of 20 participants with acute LBP were compared with a group of matched, healthy participants. Sensory organization, standing balance, and motor control strategies were assessed with the Neurocom Smart Balance Master posturography platform. The MANOVA indicated significant between-group differences in equilibrium (F = 5.58, p < 0.001) and strategy scores (F = 3.98, p = 0.006) across the six conditions of the sensory organization test. The equilibrium scores were significantly lower in participants with acute LBP compared to controls in all conditions except conditions 1 and 2 (p < 0.001). Similarly, strategy scores were significantly reduced in the acute LBP group compared to the control group in all conditions except condition 1 (p < 0.05). Visual and vestibular ratios were significantly lower in the acute LBP group than in controls (p < 0.05), whereas no significant difference was observed in somatosensory ratios between the two groups (p = 0.07). Patients with acute LBP exhibit impaired postural control and altered movement strategies under sensory challenges, highlighting the importance of early assessment and rehabilitation targeting sensorimotor deficits to reduce the risk of recurrence.
Objective: To compare the diagnostic performance of ultrasound-based area measurement with that of diaphragmatic excursion measurement for assessing sepsis-induced diaphragmatic dysfunction (SIDD). Methods: We prospectively enrolled 39 hospitalized patients with sepsis from the Department of Respiratory and Critical Care Medicine, Shengjing Hospital of China Medical University (February 2024-February 2025), and 47 healthy volunteers as controls. Bedside ultrasound was used to measure lateral thoracic area change and diaphragmatic excursion during quiet and deep breathing. Between-group differences were assessed with the Mann-Whitney U test. Receiver operating characteristic (ROC) curves were constructed and the areas under the curve (AUCs) calculated to evaluate the early predictive value of each measurement for SIDD under different respiratory states. Results: (1) During quiet breathing, lateral thoracic area change was significantly lower in the sepsis group [13.42 (8.35, 19.60) cm2] than in controls [22.02 (16.70, 31.62) cm2] (Z=-3.214, P=0.001), whereas diaphragmatic excursion did not differ significantly between groups [13.04 (10.04, 15.80) mm vs. 14.40 (10.84, 18.80) mm; Z=-1.258, P=0.208]. During deep breathing, both lateral thoracic area change [29.26 (19.08, 38.27) cm2 vs. 78.96 (59.18, 106.14) cm2] and diaphragmatic excursion [23.21 (17.79, 27.03) mm vs. 40.83 (31.20, 45.82) mm] were significantly lower in the sepsis group than in controls (both P<0.05). (2) ROC analysis yielded AUCs for lateral thoracic area change of 0.702 (quiet breathing) and 0.964 (deep breathing), and for diaphragmatic excursion of 0.579 (quiet breathing) and 0.856 (deep breathing). Conclusions: Ultrasound-based area measurement can detect early sepsis-induced diaphragmatic dysfunction during quiet breathing and does not require active breathing cooperation from the patient. It therefore has broader clinical applicability than diaphragmatic excursion measurement. Across different respiratory states, its diagnostic performance is significantly superior to that of excursion measurement, demonstrating greater diagnostic value. 目的: 比较超声面积测量法与膈肌移动度测量法评估脓毒症相关膈肌功能障碍的效能。 方法: 选取2024年2月至2025年2月于中国医科大学附属盛京医院呼吸与危重症医学科确诊脓毒症的住院患者39例,招募同时期健康志愿者47人作为对照组。利用床旁超声分别测量平静呼吸与深呼吸过程中的胸腔侧面积变化及膈肌移动度,采用Mann-Whitney U检验比较两组间各指标差异,并通过构建受试者工作特征曲线(ROC),计算曲线下面积,评估不同呼吸状态下两种测量方法对脓毒症相关膈肌功能障碍(SIDD)的早期预测价值。 结果: (1)平静呼吸状态下,胸腔侧面积变化在脓毒症组[13.42(8.35,19.60)cm2]和对照组[22.02(16.70,31.62)cm2]差异有统计学意义(Z=-3.214,P=0.001),而脓毒症组膈肌移动度[13.04(10.04,15.80)mm]与对照组膈肌移动度[14.40(10.84,18.80)mm]无统计学意义(Z=-1.258,P=0.208);深呼吸状态下,脓毒症组的胸腔侧面积变化[29.26(19.08,38.27)cm2]及膈肌移动度[23.21(17.79,27.03)mm]均低于对照组的胸腔侧面积变化[78.96(59.18,106.14)cm2]及膈肌移动度[40.83(31.20,45.82)mm],差异有统计学意义(均P<0.05)。(2)ROC曲线分析结果显示,平静呼吸与深呼吸状态下超声测量胸腔侧面积的ROC曲线下面积分别为0.702和0.964,平静呼吸与深呼吸状态下膈肌移动度的ROC曲线下面积分别为0.579和0.856。 结论: 超声面积测量法在基础呼吸状态下即可检测脓毒症相关的早期膈肌功能障碍,且不受患者呼吸配合程度的限制,较移动度测量法具有更广泛的临床应用潜力。在不同呼吸状态下,超声面积测量法的诊断效能均显著高于移动度测量法,展现出更优异的诊断价值。.
To evaluate the influence of auditory deprivation on sequential cochlear implants in postlingual patients, comparing the ear with shorter deprivation (ESAD), longer deprivation (ELAD), and the bilateral condition (BIL). Retrospective study. A tertiary referral center. Postlingually deafened patients who underwent sequential bilateral implantation between 1990 and 2021. Auditory performance was assessed over 24 months after activation of each implant. Outcomes included free-field pure-tone average (PTA), speech detection threshold (SDT), and sentence recognition in quiet and in noise at +10 dB SNR. Secondary variables were interimplant interval, duration of preimplant hearing aid use, etiology, and electrode insertion depth. ESAD outperformed ELAD in quiet (73% [IQR 44-92] vs 37% [IQR 0-87]) and in noise (27% [IQR 0-62] vs 0% [IQR 0-45]) at 24 months (P < .001). BIL achieved superior results to both monaural conditions in quiet (97% [IQR 72.5-100], P < .001) and in noise (57% [IQR 23-86.5], P = .008), regardless of ESAD experience. Interimplant interval correlated positively with BIL performance (r = 0.450; P < .001). Longer hearing aid use was negatively associated with ESAD (r = -0.293; P = .020) and BIL performance (r = -0.312; P = .018). Partial electrode insertion in ELAD was linked to poorer BIL outcomes in quiet (P = .045). No correlations were found for age or etiology. Shorter auditory deprivation and interimplant intervals are associated with better outcomes. Bilateral stimulation enhances performance even with long deprivation in 1 ear, and auditory experience with the first implant improves results. Complete insertion favors the more deprived ear, whereas prolonged ineffective hearing aid use may compromise outcomes.
Background/Objectives: Speech perception is measured in quiet and in the presence of background noise, such as multi-talker babble (MTB), to establish cochlear implant (CI) candidacy and measure post-operative outcomes. Testing protocols often use interrupted noise that begins just before and ends shortly after the target sentence, providing insufficient time for the noise-reduction algorithms to activate in the hearing device and provide an improved signal-to-noise ratio (SNR). Furthermore, interrupted noise does not allow the hearing-impaired user to acclimatize to the abrupt onset of noise or to focus on the target sentence, a challenge related to auditory stream segregation. The present study compares speech perception in bimodal CI users across interrupted and continuous MTB noise conditions to highlight performance differences between these two distinct listening environments. Methods: Speech perception was evaluated for two different bimodal CI groups. Group 1: This group evaluated an automatic hearing aid program across three environments: quiet, continuous MTB, and interrupted MTB. Group 2: This group evaluated two manual hearing aid programs across the same three environments (quiet, continuous, and interrupted MTB). Results: For Group 1, scores in quiet reached 88%, significantly declined in interrupted MTB (38%), but improved in continuous MTB (67%). For Group 2, no significant mean differences were found between interrupted and continuous noise across the two manual programs, though individual variations persisted. Conclusions: Based on the findings of this study, continuous noise rather than interrupted noise should be utilized for establishing CI candidacy and evaluating post-implantation speech perception.
