Validity and Reliability Study of the Turkish Version of the “Uncivil Behavior in Clinical Nursing Education Scale” for Nursing Students

Background and Purpose:Nursing undergraduate students may encounter unkind behaviors during their clinical education. This study aimed to test the psychometric properties of the Turkish version of the “Uncivil Behavior in Clinical Nursing Education (UBCNE) Questionnaire,” which measures nursing students’ perceived levels of uncivil behavior in the clinical learning environment.Methods:The study was conducted in four steps: translation, face and content validity, confirmatory factor analysis, and reliability assessment. Data were collected from 216 nursing students from Turkey.Results:In the exploratory factor analysis (EFA), a unidimensional factor structure with an eigenvalue above 1 was detected, and therefore the scale was analyzed as a single dimension. In the EFA with 13 items, the Kaiser–Meyer–Olkin value was 0.943, and the Barlett test result was 1862.965 (p <.05). The fit indices for the class were calculated as χ2/df= 2.218, root-mean-square error of approximation = .075, and comparative fit index = 0.961.Cronbach’s coefficient α (alpha)for Turkish culture was .942.Conclusion:The study showed that the Turkish version of the UBCNE scale is a valid and reliable measurement tool for assessing perceived incivil behaviours in nursing students’ clinical education.

Abstract 4135629: Grades and trends from the 2024 United States Report Card on Physical Activity for Children and Youth

Background: Regular physical activity provides numerous health benefits including improved cardiovascular health. Population-level physical activity surveillance is critical for informing research, practice, and policy efforts for supporting population health and health disparities. The United States Report Card on Physical Activity for Children and Youth addresses physical activity surveillance needs by integrating data from numerous sources capturing levels of physical activity and related behaviors (e.g., sedentary behavior, sleep), and facilitators and barriers for physical activity among United States youth. The 2024 Report Card is the 5 th and decennial iteration in the series, released October 2024. Methods: A Report Card Working Group was assembled under the auspices of the Physical Activity Alliance and National Physical Activity Plan. Members reviewed the evidence for 11 indicators using data from nationally representative surveys and assigned grades. Data were examined for the overall population and, when possible, by age, sex, race/ethnicity, and disability subgroups. A standardized grading rubric was used to assign a letter grade to each indicator ranging from A to F. Trends in key benchmarks over time were examined since the first report card (2014) or earliest available data. Results: Sufficient data were available to assign grades for 8 of the 11 indicators. The assigned grades ranged from B- to F, with overall physical activity levels earning a D- (Table 1). No indicators improved since 2014. Five indicators - overall physical activity, organized sport participation, active transportation, sedentary behaviors, and school - worsened since 2014. Conclusions: The compiled surveillance report indicates generally poor grades and concerning trends over the recent decade. These findings highlight opportunities to improve physical activity levels and resources for supporting cardiovascular health among United States youth. Policy approaches are needed to combat societal factors that interfere with physical activity. Gaps in data availability, specificity, and quality point to needs for improved surveillance to track impacts. The 2024 Report Card can be a tool for supporting advocacy of regular physical activity at the national and local level.

The influence of parenting styles and coping strategies on anxiety symptoms in adolescents: a comparative study of groups with and without non-suicidal self-injury behavior

Background During the COVID-19 pandemic, the global incidence of non-suicidal self-injury (NSSI) has been increasing year by year, especially among adolescents, and it is highly correlated with the level of anxiety among teenagers, particularly within Chinese cultural contexts where parenting styles significantly influence adolescent behavior. Objective This study examines the role of culturally-influenced parenting styles and adolescent coping strategies in relation to anxiety and NSSI behavior, aiming to clarify these multivariate interactions for better understanding and intervention. Methods A cross-sectional survey was conducted with NSSI-diagnosed adolescents from Affiliated Kangning Hospital, Ningbo, China, and healthy adolescents from urban schools. Data on background, parenting styles, coping strategies, and anxiety levels were analyzed using chi-square tests, independent sample t-tests, MANOVA, and regression analysis. Results Adolescents with NSSI reported higher anxiety levels, more punishment and interference, and less emotional warmth from their fathers compared to the non-NSSI group (p < 0.001). The NSSI group also relied more on emotion-oriented coping strategies, while the non-NSSI group favored problem-oriented approaches (p < 0.001). Multivariate analyses confirmed significant effects of NSSI behavior, parenting styles, and coping strategies on anxiety levels. Conclusion This study found that the anxiety levels of NSSI adolescents were significantly higher than those of non-NSSI adolescents in China, which was closely related to less emotional warmth from parents, more punishment and interference, and emotion-focused coping strategies. The results demonstrate that family environment and coping strategies play a critical role in NSSI behavior and anxiety levels, highlighting the importance of emphasizing emotional support and positive coping strategies in the prevention and intervention of NSSI behavior.

Cannula Implantation Reduces the Severity of the Beta Amyloid Effect on Peroxidized Lipids and Glutathione Levels in the Brain of BALB/c Mice

Sporadic Alzheimer’s disease (sAD) is the most common of neurodegenerative disorders. The lack of effective therapy indicates that the mechanisms of sAD development remain poorly understood. To investigate this pathology in animals, intracerebroventricular injection of β-amyloid peptide (Aβ) using a Hamilton syringe, either during stereotactic surgery or through a pre-implanted cannula, is used. In this study, we analyzed the effect of chronic cannula implantation on the severity of Aβ effects at the behavioral, histological, and biochemical levels. The results showed that the local damage to neural tissue caused by cannulation has no bearing on the effect of Aβ on animal behavior and the microglial parameters of the unilateral hippocampus two weeks after the Aβ administration. However, cannula implantation fundamentally modifies some biochemical markers of the oxidative stress that occurs in the brain tissue in response to Aβ administration. Thus, the presence of a cannula reduces the severity of the Aβ impact on the levels of peroxidized lipids and glutathione two- and 10-fold, respectively. It is important to note that the detected changes are chronic and systemic. This is known because the homogenate of the entire contralateral (in relation to the cannula implantation site) hemisphere was analyzed, and the analysis was performed two weeks after implantation. At the same time, cannulation does not affect the rate of reactive oxygen species production. The obtained data indicate that chronic implantation of a cannula into the brain of experimental animals fundamentally distorts some parameters of oxidative stress in the neural tissue, which are widely used to assess the severity of experimental Alzheimer’s-type diseases.

New Vistas for the Relationship between Empathy and Political Ideology

The study of ideological asymmetries in empathy has consistently yielded inconclusive findings. Yet, until recently these inconsistencies relied exclusively on self-reports, which are known to be prone to biases and inaccuracies when evaluating empathy levels. Very recently, we reported ideological asymmetries in cognitive-affective empathy while relying on neuroimaging for the first time to address this question. In the present investigation which sampled a large cohort of human individuals from two distant countries and neuroimaging sites, we re-examine this question, but this time from the perspective of empathy to physical pain. The results are unambiguous at the neural and behavioral levels and showcase no asymmetry. This finding raises a novel premise: the question of whether empathy is ideologically asymmetrical depends on the targeted component of empathy (e.g., physical pain vs cognitive-affective) and requires explicit but also unobtrusive techniques for the measure of empathy. Moreover, the findings shed new light on another line of research investigating ideological (a)symmetries in physiological responses to vicarious pain, disgust, and threat.Significance StatementIn this study, we challenge the historically inconclusive findings on ideological asymmetries in empathy. By employing neuroimaging techniques, we demonstrated that ideological asymmetry in physical pain empathy is absent. This research underscores the importance of considering various facets of empathy, societal contexts, and unbiased measurement methodologies, such as neuroimaging techniques, in the assessment of empathic responses.

Crack Control in Additive Manufacturing by Leveraging Process Parameters and Lattice Design

This study investigates the design of additive manufacturing for controlled crack propagation using process parameters and lattice structures. We examine two lattice types—octet-truss (OT) and diamond (DM)—fabricated via powder bed fusion with Ti-6Al-4V. Lattice structures are designed with varying densities (10%, 30%, and 50%) and process using two different laser energies. Using additive-manufactured specimens, Charpy impact tests are conducted to evaluate the fracture behavior and impact energy levels of the specimens. Results show that the type of the lattice structures, the density of the lattice structures, and laser energy significantly influence crack propagation patterns and impact energy. OT exhibits straighter crack paths, while DM demonstrates more random fracture patterns. Higher-density lattices and increased laser energy generally improve the impact energy. DM consistently outperformed OT in the impact energy for angle specimens, while OT showed superior performance in stair specimens. Finally, a case study demonstrates the potential for combining OT and DM structures to guide crack propagation along predetermined paths, offering a novel approach to protect critical components during product failure.

Stereoscopic objects affect reaching performance in virtual reality environments: influence of age on motor control

Although the stereoscopic effect in 3D virtual reality (VR) space has been studied, its influence on motor performance, specifically how stereoscopic objects affect behavioral outcomes like reaching, remains unclear. Previous research has primarily focused on perceptual aspects rather than on how stereoscopic visual input impacts motor control at the behavioral level. Thus, we investigated the effects of stereoscopic objects in a VR environment on reaching performance, examining whether the stereoscopic effect of objects is a significant aspect enough to affect performance at the behavioral level. While doing so, we investigated young and older adults separately, as age is a critical factor influencing motor performance. Fourteen young and 23 older participants performed a reaching task in the VR space. The target objects were 2D and 3D, deviating from the initial position by 10 and 20 cm. The movement attributed to feedforward control was analyzed using end-point error and smoothness of movement. Our results revealed that older participants had significantly worse predictive control than young participants in the 3D long task, suggesting that the positions of 3D objects were more difficult to predict than those of 2D objects. Young participants showed a significant difference in smoothness between 2D and 3D objects, which was not observed in older participants. This may reflect the floor effect in older participants. Under the short-distance condition, neither group showed a significant difference, suggesting the ceiling effect by distance. We confirmed that the effect of stereoscopic objects was not drastic but it did hamper the reaching performance.

Nursing practice of guidelines for prevention and control of vascular Catheter-Related bloodstream infections.

To apply the Ottawa Model of Research Use to translate the Guidelines for the Prevention and Control of Vascular Catheter-Associated Bloodstream Infections. The Ottawa model of research use is used to provide a framework and guidance. This study was organized by the Nursing Department of the Affiliated Hospital of Hebei Engineering University, and the Intravenous Therapy Group was responsible for the implementation of the study. The hospital's intravenous therapy administrators, members of the sedation team, and specialist nurses will be organized to evaluate the importance, exactness, and clinical practicability of 34 entries. Twelve clinical departments and IV therapy clinics with a high number of central venous catheters were used as sites for translating evidence from this project. The evidence-based team assessed the practice environment, potential practitioners, and clinical status of clinical translation of evidence through symposia, review of relevant systems, operational procedures, on-site inspections, and questionnaires. They compare evidence with existing processes and decide on change strategies. Before and after the application of the evidence, there was a significant increase in the knowledge, belief, and behavior of healthcare workers on CLABSI prevention and control, especially in the acquisition of related knowledge (χ2 = 26.648 p < 0.001). The associated implementation rate was also significantly improved, with a significant decrease in CLABSI incidence from 0.29 per 1000 to 0.11 per 1000 (χ2 = 8.625 p = 0.004). The assessment of the integration of issues showed that 8 aspects, including workflow, knowledge mastery, monitoring reports, and aseptic operations, do not meet the qualified standards. Through this clinical change, a perfect prevention and control system has been established, and the level of knowledge, belief, and behavior of medical staff in preventing CLABSI has been improved, while the incidence of CLABSI has been reduced.

Person-Environment Fit on Organizational Citizenship Behaviour and Employee Engagement Among Administrative Staff of Public Universities in Accra, Ghana

This study aimed to assess the impact of person-environment fit on work-related outcomes among administrative staff of public universities in Accra. A sample of 300 administrative staff was selected from public universities in the Greater Accra Region to partake in the study using the purposive and snowball sampling method. The study discovered a positive significant relationship between employees fit and work-related outcomes as well as an interaction between two dimensions of engagement (intellectual and affective) and organizational citizenship behavior. The study's findings also reveal that various factor such as tenure and age positively impacted the employee’s performance of organizational citizenship behavior and engagement levels.

Testing the impact of hatha yoga on task switching: a randomized controlled trial

Switching attention between or within tasks is part of the implementation and maintenance of executive control processes and plays an indispensable role in our daily lives: It allows us to perform on distinct tasks and with variable objects, enabling us to adapt to and respond in dynamically changing environments. Here, we tested if yoga could benefit switching of attention between distinct objects of one’s focus (e.g., through practicing switching between one’s own body, feelings, and different postures) in particular and executive control in general. We therefore conducted a randomized controlled trial with 98 participants and a waitlisted control group. In the intervention group, healthy yoga novices practiced Hatha yoga 3x a week, for 8 weeks. We conducted two experiments: A purely behavioral task investigating changes in behavioral costs during switching between attentional control sets (74 participants analyzed), and a modality-switching task focusing on electrophysiology (EEG data of 47 participants analyzed). At the electrophysiological level, frequency-tagging indicated no interventional effect on participants’ ability to switch between the auditory and visual modalities. However, increases in task-related frontocentral theta activity, resulting from the intervention, indicated an ability to increasingly deploy executive resources to the prioritized task when needed. At the behavioral level, our intervention resulted in more efficient holding of target representations in working memory, indicated by decreased mixing costs. Again, however, intervention effects on switching costs were missing. We, thus, conclude that Hatha yoga has a positive influence on executive control, potentially through improvements in working memory rather than directly on switching.Clinical trial registrationclinicaltrials.gov, identifier [NCT05232422].

Investigation on the failure mechanism of slope deformations induced by water level fluctuation with InSAR and numerical simulation: a case study

The Alagou Reservoir was officially closed for water storage in November 2014. Since September 2016, gradual slope collapse and deformation have been observed at elevations ranging from 600 to1050 m upstream of the left bank of the Alagou Reservoir dam site. The increasing annual deformation raises significant concerns about a potential landslide, which could lead to surge waves, posing a threat to both the dam and the surrounding environment. Due to difficult access and worsening conditions, thorough exploration of the site was challenging. Consequently, After emptying the reservoir, we conducted on-site investigations using satellite D-InSAR analysis, numerical modeling, and post-event monitoring. This multidisciplinary approach aimed to investigate the relationship between deformation behavior, triggering conditions, and reservoir water level changes. Our study provides valuable insights into the complex geological processes involved in slope deformation and failure mechanisms induced by water level fluctuations. We elucidated the interplay between deformation behavior and triggering conditions, which is essential for designing effective reinforcement treatments for deformed slopes. While InSAR has proven to be a cost-effective tool for monitoring surface deformation, it offers limited insights alone. Therefore, we recommend a multi-technique approach incorporating geophysical, geotechnical, and remote sensing data for a comprehensive understanding of slope stability.

The Role of Probiotics in Modulating Myocardial Infarction and Depression-like Symptoms: A Study on Sex-Specific Responses

Background/Objectives: This study explores the effects of two probiotics, Lactobacillus helveticus R0052 and Bifidobacterium longum R0175, on myocardial infarction (MI) and associated depression-like behaviours, with a focus on sex differences. Methods: MI was induced in adult male and female rats by occluding the left anterior coronary artery for 30 min, followed by 24 h of reperfusion. Probiotics were administered via drinking water for at least two weeks before ischemia. Infarct size, plasma C-reactive protein (CRP), estradiol levels, and intestinal permeability were then measured. Two weeks after, MI subgroups of rats were tested for depression-like behaviours. Results: We found a significant interaction between sex and probiotics in relation to infarct size. Probiotics significantly reduced the infarct size compared to the vehicle group in female rats but not in males. Probiotics increased the plasma estradiol levels and reduced the CRP concentrations in females, suggesting anti-inflammatory and cardioprotective properties. Probiotics significantly increased intestinal resistance following MI in males only, suggesting sex-specific physiological responses to treatment. Probiotics enhanced social interaction in males with MI but not in females. Similarly, in the forced swim test, probiotics reduced immobility in males with MI but increased it in females, further underscoring the sex-dependent effects of probiotics. Conclusions: This study reports cardioprotective effects of probiotics upon MI in female rats, while benefits in male rats were rather at the behavioural level. These results highlight distinct physiological and behavioural responses between sexes, emphasizing the need to account for sex differences in future tests of probiotics as a prophylactic treatment for MI.

Citizen science promotes knowledge, skills and collective action to monitor and protect freshwater streams

Abstract Citizen science has great potential to foster ecological knowledge, skills and collective action for biodiversity conservation. To date, however, there are few experimental studies of behaviour change outcomes induced by citizen science. We assessed the effects of citizen science in ecological stream monitoring on participants' individual and collective behaviour and action intentions to protect streams beyond the immediate scope of the citizen science project. For this we applied a three‐wave, quasi‐experimental survey design with a citizen science treatment group (N = 213 participants of the project FLOW in Germany) and two control groups (waiting control group: N = 92, panel control group: N = 250). In addition, we analysed citizen science effects on potential predictors of freshwater conservation behaviour, such as knowledge, skills, awareness of stream stressors and group identification. Results of linear mixed‐model analysis showed that, compared to the control groups, citizen scientists significantly increased their objective stream‐related knowledge, their self‐reported stream monitoring skills and their awareness of stream stressors. These changes remained stable 6 weeks after the citizen science intervention. Notably, citizen scientists also reported increased identification with their citizen science project group and higher levels of collective and personal behaviour to protect streams at posttest (e.g. contacting local politicians with ideas for stream protection or using biodegradable detergents). Analysis revealed that increases in group identification and collective stream protection behaviour were significantly correlated. We could show that the citizen science intervention was particularly effective for participants with high intrinsic motivation and for those with low prior knowledge and experience in stream monitoring. Synthesis and applications. Citizen science can serve as a useful tool to promote ecological understanding, awareness and collective action to conserve freshwater streams. By fostering volunteer skills and community building, citizen science projects can empower participants with different levels of experience to engage in freshwater monitoring and protection. Decision makers should actively support approaches for citizen participation in freshwater monitoring, recognising that collective engagement of diverse community members is needed to finally meet the European Water Framework Directive's goal of restoring the good ecological status of freshwater ecosystems.

Effectiveness of the Additional Risk Minimisation Measures for Valproate Among Healthcare Professionals and Patients: A Cross‐Sectional Survey in Six European Countries

ABSTRACTPurposeTo assess the impact of the 2018 European additional risk minimisation measures (aRMMs) regarding the use of valproate in women of childbearing potential (WCBP) and during pregnancy.MethodsA cross‐sectional, non‐interventional survey conducted in six European countries among 1982 healthcare professionals (HCPs) (July–October 2020) and 779 WCBP treated with valproate for epilepsy, bipolar disorder or other indications (August 2020–February 2021). HCPs were prescribing physicians (neurologists, psychiatrists, paediatricians and GPs), gynaecologists and pharmacists. Prespecified criteria were defined for success in the dimensions of awareness, knowledge and behaviour (correct answers to ≥ 80% of questions at individual level) and overall success (≥ 90%/80% successful HCPs/patients respectively, in the behaviour dimension and one of the two other dimensions).ResultsHCPs and patients did not meet the success criteria either overall or in any dimension. Highest success rates were in the behaviour dimension for gynaecologists (71.7%), pharmacists (49.7%) and patients (51.2%), and in the awareness dimension for prescribing physicians (23.6%). HCPs reported being unfamiliar with some educational materials and lacked knowledge of detailed prescribing conditions for valproate and the need for contraception regardless of sexual activity. More than 50% of patients were aware of the relevant patient materials and knew about the teratogenic risks of valproate.ConclusionSelf‐reported levels of awareness, knowledge and behaviour varied considerably by HCP type and among patient respondents. Further investigation is needed into why certain measures of the pregnancy prevention programme are not well known and followed, to improve their effectiveness. This will be addressed in a qualitative study which will be based on interviews with HCPs and patients.

Suicidal behaviors questionnaire-revised: Adaptation and psychometric properties of the Brazilian version

Suicidal behaviors are a significant concern in Latin American countries. However, validated scales in Brazil do not address all behaviors on the suicide spectrum. We aimed to adapt the Suicidal Behaviors Questionnaire-Revised (SBQ-R) for Brazil. The SBQ-R was independently translated, back-translated, and evaluated by experts—two thousand eight hundred ninety-eight participants (68.30% women; M = 27.42; A = 18–69) from Brazil. The SBQ-R items presented adequate reliability (ω = .86). Confirmatory factor analysis (CFA) confirmed the construct validity (χ2(df) = 52.707(2), p<.001; CFI = .997; TLI = .992; RMSEA = .052; SRMR = .024). Multigroup CFA indicated that the SBQ-R is invariant for gender, sexual orientation, race, and education level. The SBQ-R has convergent validity for depression (r = 0.61), anxiety (r = 0.49), stress (r = 0.49), impulsivity (r = 0.40), hopelessness (r = 0.60) and divergent validity, with gender and sexual minorities showing higher levels of suicidal behaviors. The Brazilian SBQ-R is designated for use by Brazilian adults. Future studies must investigate the predictive validity of the SBQ-R in clinical samples.

Understanding inconsistencies in risk attitude elicitation games: Evidence from smallholder farmers in five African countries

Recent empirical studies eliciting farmers’ risk attitudes through lab-in-the-field experiments have reported high levels of inconsistency in responses. We investigate inconsistencies in risk attitudes elicitation games using data from incentivized lotteries involving 2,319 smallholder farmers from Eastern Africa (Kenya, Uganda, Tanzania) and Northern Africa (Tunisia, Morocco). Our sample demonstrates high levels of inconsistent behavior, with 48% of the farmers exhibiting some type of inconsistency. Depending on the country, inconsistencies are explained by poverty, gender, and/or the interaction of gender and level of education. We find no significant impact (negative or positive) of education alone in all but one country model. Furthermore, we find session fixed effects to significantly explain inconsistencies in many cases, suggesting that session-specific circumstances, including inconsistencies across enumerators, play a crucial role in the successful implementation of these experiments. Our findings suggest that using risk attitude parameters without accounting for the presence and the potential causes of inconsistency may lead to unreliable results. This study may guide practitioners in identifying farmer typologies more prone to inconsistent decisions and inform policymakers about factors influencing operators’ choices.

Impact of a natural rubber-based scratcher as an environmental enrichment on the scratching behavior, cortisol level, and semen quality of stable male goats

Background and Aim: Goats are valuable livestock because they can generate meat and milk for human consumption. Goat husbandry is becoming more intensive due to the growing demand for goat products, which may impact animal welfare and natural behavior. This study aimed to investigate the impact of natural rubber (para rubber)-based scratchers as an environmental enrichment on scratching behavior, cortisol levels, and semen quality in stable bucks (male goats/goats). Materials and Methods: Nine male goats were used in this study. Scratching behavior and cortisol levels were used as welfare indicators, whereas semen quality was evaluated as an indicator of reproductive potential. These indicators were analyzed before and after scratcher installation. Results: After installing the scratchers, the goats showed a significant increase in scratching behavior and a notable decrease in cortisol levels (p &lt; 0.001). Notably, the goats exhibited a marked preference for scratching against the scratcher (p &lt; 0.001) compared to the stable. They significantly preferred using their heads for scratching (p &lt; 0.001) instead of other body parts. In addition, goats preferred to scratch on the softest rubber scratchers at specific installation locations (p &lt; 0.001). Although there was a slight improvement in semen quality, there was no statistically significant difference (p &gt; 0.05). Conclusion: A natural rubber-based scratcher can increase scratching behavior and reduce cortisol levels, indicating its potential to improve the welfare of farm goats. Selecting an appropriate hardness and preferred location is essential to ensure that the scratcher effectively encourages animals to use it. Keywords: cortisol, goat, para rubber, scratcher, semen quality.

Effects of the Tools for Getting Along Curriculum on Teachers’ Reports of Elementary Students’ Executive Functions, Social-Emotional Skills, and Behavior Problems

In this study, we examined the effectiveness of Tools for Getting Along (TFGA) on teachers’ reports of executive functioning (EF), social-emotional, and behavioral skills of upper elementary school students. TFGA is a classroom-level prevention curriculum that teaches students a sequence of empirically based problem-solving steps to apply in emotionally charged situations. We randomly assigned 52 elementary schools in California, Oklahoma, and Kentucky to the treatment (n = 26) or comparison (n = 26) condition, with study participants including 135 grade 4 teachers and their 1,713 students. Multilevel analyses revealed that relative to those in the comparison group, students who participated in TFGA had significantly better social skills (effect size = 0.12) and higher levels of behaviors associated with EFs (effect size = 0.11), as reported by their teachers. Further, students whose teachers reported as having higher internalizing and externalizing behaviors, lower competence, and weaker behaviors associated with EFs at baseline experienced greater improvements in these skills after participating in TFGA than their counterparts with relatively stronger skills in the comparison group. We discuss educational implications of this study to promote and scale evidence-based, social-emotional practices in elementary school classrooms.

Effects of Physical Activity Level and Sedentary Behavior on the Musculoskeletal System in Young Adults

Aim: The aim of this study is to investigate the relationship between the level of physical activity and sedentary behavior in young adults aged 18-35 and to evaluate the effects of this relationship on musculoskeletal pain, posture, muscle shortness, and trunk muscle endurance. Methods: In this cross-sectional descriptive study, conducted at the Faculty of Health Sciences of a university between March 2018 and August 2018, 219 students were included. Data were obtained by using the case report form which determines the demographic characteristics and sedentary behavior of the students, The International Physical Activity Index - short form, posture analysis form, muscle shortness evaluation form, and trunk muscle endurance evaluation form. Results: In the study, 66.2% of patients were female and 33.8% were male. In the evaluation of physical activity level, the ratio of highly active individuals in males, and inactive and insufficiently active individuals in females was significantly higher (p &amp;lt;0.05). Musculoskeletal pain was significantly higher in inactive and insufficiently active individuals (p&amp;lt;0.001). A negative correlation existed between physical activity level and pain frequency, duration, and scores (p&amp;lt;0.001). There was a positive correlation between trunk endurance tests and physical activity and exercise participation. Non-exercisers showed shortening of lumbar extensor muscles and gastrosoleus, with increased thoracic kyphosis (p&amp;lt;0.05). Daily sitting time correlated positively with elbow, wrist, and knee pain, and lumbar lordosis (p&amp;lt;0.05). Those spending more time at the computer experienced higher levels of head-neck and elbow pain, pain duration, muscle shortness, thoracic kyphosis, shoulder protraction, and anterior head tilt (p&amp;lt;0.05). Conclusion: In young adults, increasing physical activity and reducing daily sitting time are necessary to prevent musculoskeletal pain and reduce postural deformities. Keywords: Musculoskeletal diseases, musculoskeletal pain, physical exertion, posture, sedentary behavior, trunk muscular endurance, young adult.

Going the Extra Mile: What Drives Employee Voluntarism in Public Sector Organizations?

This research intends to investigate the impact of employee age and innovative work climate on the relationship between supportive supervisory roles and employee acts of voluntarism. Using a large cross-sectional survey of the Australian Public Service we find that the influence of supportive supervisors on employees’ acts of voluntarism and extra role behaviors at work is higher amongst younger employees. This indicates that younger employees are more likely to engage in acts of voluntarism as a result of supportive supervisory roles. Findings also indicate that innovative work climate accentuates the relationship between supportive supervisory behaviors and acts of voluntarism. Employees who experience high levels of innovative work climate and high levels of support from supervisors tend to display higher levels of voluntarism and extra role behaviors at work. These findings have several theoretical and practical implications.
