Head Exposure to Acceleration Database in Sport (HEADSport): a kinematic signal processing method to enable instrumented mouthguard (iMG) field-based inter-study comparisons.

Objective: Instrumented mouthguard (iMG) systems use different signal processing approaches limiting field-based inter-study comparisons, especially when artefacts are present in the signal. The objective of this study was to assess the frequency content and characteristics of head kinematic signals from head impact reconstruction laboratory and field-based environments to develop an artefact attenuation filtering method (HEADSport filter method). Methods: Laboratory impacts (n=72) on a test-dummy headform ranging from 25 to 150 g were conducted and 126 rugby union players were equipped with iMGs for 209 player-matches. Power spectral density (PSD) characteristics of the laboratory impacts and on-field head acceleration events (HAEs) (n=5694) such as the 95th percentile cumulative sum PSD frequency were used to develop the HEADSport method. The HEADSport filter method was compared with two other common filtering approaches (Butterworth-200Hz and CFC180 filter) through signal-to-noise ratio (SNR) and mixed linear effects models for laboratory and on-field events, respectively. Results: The HEADSport filter method produced marginally higher SNR than the Butterworth-200Hz and CFC180 filter and on-field peak linear acceleration (PLA) and peak angular acceleration (PAA) values within the magnitude range tested in the laboratory. Median PLA and PAA (and outlier values) were higher for the CFC180 filter than the Butterworth-200Hz and HEADSport filter method (p<0.01). Conclusion: The HEADSport filter method could enable iMG field-based inter-study comparisons and is openly available at https://github.com/GTBiomech/HEADSport-Filter-Method.

Deep learning classification of systemic sclerosis from multi-site photoplethysmography signals.

Introduction: A pilot study assessing a novel approach to identify patients with Systemic Sclerosis (SSc) using deep learning analysis of multi-site photoplethysmography (PPG) waveforms ("DL-PPG"). Methods: PPG recordings having baseline, unilateral arm pressure cuff occlusion and reactive hyperaemia flush phases from 6 body sites were studied in 51 Controls and 20 SSc patients. RGB scalogram images were obtained from the PPG, using the continuous wavelet transform (CWT). 2 different pre-trained convolutional neural networks (CNNs, namely, GoogLeNet and EfficientNetB0) were trained to classify the SSc and Control groups, evaluating their performance using 10-fold stratified cross validation (CV). Their classification performance (i.e., accuracy, sensitivity, and specificity, with 95% confidence intervals) was also compared to traditional machine learning (ML), i.e., Linear Discriminant Analysis (LDA) and K-Nearest Neighbour (KNN). Results: On a participant basis DL-PPG accuracy, sensitivity and specificity for GoogLeNet were 83.1 (72.3-90.9), 75.0 (50.9-91.3) and 86.3 (73.7-94.3)% respectively, and for EfficientNetB0 were 87.3 (77.2-94.0), 80.0 (56.3-94.3) and 90.1 (78.6-96.7)%. The corresponding results for ML classification using LDA were 66.2 (53.9-77.0), 65.0 (40.8-84.6) and 66.7 (52.1-79.2)% respectively, and for KNN were 76.1 (64.5-85.4), 40.0 (19.1-63.9), and 90.2 (78.6-96.7)% respectively. Discussion: This study shows the potential of DL-PPG classification using CNNs to detect SSc. EfficientNetB0 gave an overall improved performance compared to GoogLeNet, with both CNNs performing better than the traditional ML methods tested. Our automatic AI approach, using transfer learning, could offer significant benefits for SSc diagnostics in a variety of clinical settings where low-cost portable and easy-to-use diagnostics can be beneficial.

A New MBH Adduct as an Efficient Ligand in the Synthesis of Metallodrugs: Characterization, Geometrical Optimization, XRD, Biological Activities, and Molecular Docking Studies.

This article reports the synthesis, characterization, geometrical optimization, and biological studies of new MBH-based organometallic compounds of medicinal significance. The ligand (MNHA) was prepared via the Morita-Baylis-Hillman (MBH) synthetic route, from aromatic aldehyde containing multiple functional groups. Metal complexes were prepared in an alkaline medium and under other suitable reaction conditions. Spectral and elemental analyses were used to identify the structural and molecular formulas of each compound. Optimized geometry was determined through density functional theory (DFT) B3LYP and 6-311++ G (d,p) basis set for the MBH adduct, whereas structures of novel complexes were optimized with the semi-empirical PM6 method. Powder XRD analysis furnished the crystal class of complexes, with Co3+, Cr3+, and Mn2+ being cubic, while Ni2+ was hexagonal, and Cu2+ was orthorhombic. Moreover, the ligand, along with Ni2+ and Co3+ complexes, showed profound antibacterial action against S. aureus, E. coli, B. pumilis, and S. typhi. Additionally, all of the complexes were shown to persist in the positive antioxidant potential of the ligand. Contrarily, not a single metal complex conserved the antifungal potentials of the ligand.

"Doing good and feeling good" Relationship between authentic leadership with followers' work engagement: The mediating role of hedonic and eudaimonic wellbeing.

The positive behavioral style of authentic leadership has attracted academicians' and practitioners' attention to focus more on a healthy workplace environment and its influence on followers' valued workplace relationship outcomes, such as employees' work engagement. From the lens of social exchange perspective, we tested a unified model of authentic leadership and its influence on the followers' wellbeing (hedonic and eudaimonic wellbeing) and work engagement. We also examined the mediating role of hedonic and eudaimonic wellbeing on followers' work engagement. Using a time-lagged design, we collected data from 250 telecom sector workers employed in the capital city of Islamabad, Pakistan. The results indicate the positive influence of authentic leadership on followers' work engagement and employees' hedonic and eudaimonic wellbeing. Hedonic and eudaimonic wellbeing also positively mediated the relationship between authentic leadership and followers' work engagement. The theoretical and practical implications of the study are also discussed.

Taking cognizance of the medicinal significance and diverse functions of synthetic Morita-Baylis-Hillman adducts (MBHA), the title ligand was synthesized and purified through column chromatography. Cr+3, Mn+2, Co+3, Ni+2, Cu+2 complexes of the ligand were synthesized under basic conditions, subjected to characterization through spectral analyses and verified with the IR spectrum that was generated computationally by the DFT B3LYP method, with 6-311++ G (d,p) basis set and Hartree Fock (HF) B3LYP method in conjunction with 3-21G(d,p) basis set. Powder XRD helped to testify crystals of the complexes. Moreover, the antibacterial, and antioxidant characteristics of MBHA and its complexes were also established. All of them were found to be active antioxidants. The antibacterial activities, examined against S. aureus, E. coli, B. pumilis and S. typhi have revealed that its Cobalt complex has an excellent potential to act against all of them. Hence, these compounds maybe having potentialities for the discovery of new, cheaper and efficient drugs against various infectious diseases. The study also uncovers the first example of utilization of MBHA towards metal complex formation.

Deciphering waste bound nitrogen by employing psychrophillic Aporrectodea caliginosa and priming of coprolites by associated heterotrophic nitrifiers under high altitude Himalayas.

Himalayan ecosystem is characterized by its fragile climate with rich repositories of biodiversity. Waste collection and disposal are becoming increasingly difficult due to topographical variations. Aporrectodea caligenosa, a versatile psychrophillic soil dweller, is a useful biocatalyst with potent bio-augmented capability for waste treatment at low temperatures. Microcosm experiments were conducted to elucidate the comprehensive nature of biogenic nitrogen transformation to NH4+ and NO3- produced by coupling of earthworm-microbes. Higher biogenic recovery of NH4+-N from coprolites of garden soil (47.73 ± 1.16%) and Himalayan goat manure (86.32 ± 0.92%) with an increment of 14.12 and 47.21% respectively over their respective control (without earthworms) with a linear decline beyond 4th week of incubation was reported. NO3--N recovery progressively sustained in garden soil and goat manure coprolites during entire incubation with highest 81.81 ± 0.45 and 87.20 ± 1.08 µg-N g-1dry weight recorded in 6th and 5th week of incubation respectively and peak increments as 38.58 and 53.71% relative to respective control (without earthworms). Declined NH4+-N in coprolites at low temperature (15.0 ± 2.0 °C) evidenced increased nitrification rates by taking over the process by abundant nitrifying microbes. Steady de-nitrification with progressive incubation on an average was 16.95 ± 0.46 ng-N g-1 per week and 21.08 ± 0.87 ng-N g-1 per week compared to 14.03 ± 0.58 ng-N g-1 per week and 4.50 ± 0.31 ng-N g-1 per week in respective control treatments. Simultaneous heterotrophic nitrification and aerobic denitrification (SHNAD) was found to be a prominent bioprocess at low temperature that resulted in high and stable total nitrogen and nitrate accumulation from garden soil and goat manure with relative recovery efficiency of 11.12%, 14.97% and 14.20%; 19.34%. A. caligenosa shows promising prospects for mass applicability in biogenic N removal from manure of Himalayan goat.

Spectrum of Dyslipidemias in Treatment-Naïve Human Immunodeficiency Virus-Infected Patients Presenting to an HIV Clinic of a Tertiary Care Hospital.

Introduction HIV/AIDS is a major communicable disease worldwide, especially in developing countries where disease prevalence is over 90%. The National AIDS Control Programme of Pakistan reported around 160,000 HIV cases (140,000-190,000) with a 5% prevalence among traditional risks groups. HIV infection is thought to affect lipids metabolism adversely, thus resulting in increased morbidity and mortality. The aim of the study was to find out the frequency and types of dyslipidemia in patients with HIV not taking anti-retroviral therapy, presenting to an HIV clinic at a tertiary care hospital. Methods This cross-sectional study was conducted at the HIV clinic of Jinnah Hospital from January 2020 to July 2020. A total of 280 treatment-naïve patients, fulfilling the inclusion protocol, were included through non-probability consecutive sampling after informed consent. Blood samples of 5 mL were taken using aseptic measures and following standard procedure after ensuring overnight fasting by a nurse and were sent immediately to the pathology laboratory of Allama Iqbal Medical College. The results of the lipid profile were collected the next day and noted in the proforma. Dyslipidemia and type of dyslipidemia were recorded as per operational definition. Data were analyzed by SPSS software, version 27.0 (IBM Corp., Armonk, NY). Cross-tabulation was done to assess the relationship of gender, BMI, and family history on dyslipidemia, and a chi-square test was applied to check statistical significance. Results Among 280 treatment-naïve HIV-infected patients, the majority of patients were females (52%). The mean duration of HIV was 9.31 + 2.13 months. About 55% of patients had a BMI of more than 25 kg m2. A family history of dyslipidemia was found in 62% of the patients. Dyslipidemia was observed in 70% of patients with maximum derangement seen in total cholesterol level (62%). After applying the chi-square test, a significant relation was identified between BMI and family history with dyslipidemia in HIV-infected individuals (p-value = 0.00). Conclusion A considerable proportion of treatment-naïve HIV patients have underlying dyslipidemia with a significant relationship with higher BMI and a family history of dyslipidemia. The findings of this study highlight the importance of early screening for dyslipidemia in HIV patients.

Determining the Association Between Helicobacter pylori Infection and Treatment-Refractory Hypothyroidism.

Introduction Refractory hypothyroidism, despite weight-based thyroxine dosing, is a common endocrinology consultation in outpatients. Chronic Helicobacter (H.) pylori infection has been reported to be responsible for the poor absorption of thyroxine from the small gut leading to suboptimal response with contradictory evidence. This study was carried out to determine the association of chronic Helicobacter pylori infection with refractory hypothyroidism in outpatients presenting to a tertiary care hospital. Methods One hundred thirty patients with the diagnosis of hypothyroidism, visiting Jinnah Allama Iqbal Institute of Diabetes and Endocrinology (JAIDE) Jinnah Hospital Lahore, Pakistan, from January 2020 to February 2021, were included in the study after informed consent following the non-probability consecutive sampling technique. All of these patients were 15-70 years of age, non-pregnant, and receiving thyroxine treatment for at least six weeks. Patients with a history of gastric surgery, malabsorption syndrome, or poor compliance were excluded from the study. Patients' age, sex, and body mass index (BMI) were recorded in a structured proforma. Patients were categorized into two groups, i.e. controls (biochemically euthyroid on thyroxine treatment with TSH < 4.5mU/L) and cases (refractory hypothyroidism despite 1.6 mcg/kg thyroxine treatment with TSH > 4.5 mU/L). The presence of chronic H. pylori infection was checked with serum immunoglobulin G (IgG) testing by enzyme-linked immunoassay (ELISA) from the hospital laboratory and data analysis was done by SPSS version 21.0 (IBM Corp., Armonk, NY). Results One hundred thirty patients were included in this study, with an age range from 15 to 70 years. Of these, 65/130 (50%) were euthyroid on treatment and 65/130 (50%) had treatment-refractory hypothyroidism. The mean age of patients in our study was 45.81 ± 11 years, with 118 (90.8%) female patients. The prevalence of positive H. pylori IgG antibody was 47/130 (36.2%) overall, with 23 patients (35.4%) in the control (euthyroid) group and 24 patients (36.9%) in the cases (refractory hypothyroidism) group. The difference between the two groups was not statistically significant with an odds ratio of 1.069 (CI 0.523 - 2.187) and a p-value of 0.855. Moreover, age, gender, and BMI had no effect on chronic H. pylori association with refractory hypothyroidism. Conclusion This study does not suggest any significant association between chronic H. pylori infection and treatment-refractory hypothyroidism. Other factors like poor compliance, drug-drug interactions, and malabsorption disorders should be preferably sought in case of refractory hypothyroidism.

Impact of Supportive Leadership During Covid-19 on Nurses' Well-Being: The Mediating Role of Psychological Capital.

The corona virus disease (Covid-19) has significantly affected the social, physical, and psychological health of workers, specifically the nurses working in the healthcare sectors. Studies have been conducted on the impact of Covid-19 on employees' well-being, organizational structure, and job design; however, limited studies have been conducted focusing on the impact of leadership on employee's well-being during the Covid-19 pandemic. Drawing on job demands resources model and social exchange theory, we examined the impact of supportive leadership on employees' physical, social, and psychological well-being during the Covid-19 pandemic. In addition, we examined the mediating role of psychological capital in examining the relationship between supportive leadership and employees' physical, social, and psychological well-being. Based on three wave time-lagged design, the data were collected from 214 nurses' linear regression analysis and Hayes Process for mediation to test the proposed hypothesis. As hypothesized, supportive leadership predicted employees' physical, social, and psychological well-being. In addition, psychological capital mediated the relationship between supportive leadership and employees' physical, social, and psychological well-being. Implications for research, theory, and practice are discussed.

Proteomic signatures for perioperative oxygen delivery in skin after major elective surgery: mechanistic sub-study of a randomised controlled trial.

BACKGROUND: Maintaining adequate oxygen delivery (DO2) after major surgery is associated with minimising organ dysfunction. Skin is particularly vulnerable to reduced DO2. We tested the hypothesis that reduced perioperative DO2 fuels inflammation in metabolically compromised skin after major surgery. METHODS: Participants undergoing elective oesophagectomy were randomised immediately after surgery to standard of care or haemodynamic therapy to achieve their individualised preoperative DO2. Abdominal punch skin biopsies were snap-frozen before and 48 h after surgery. On-line two-dimensional liquid chromatography and ultra-high-definition label-free mass spectrometry was used to characterise the skin proteome. The primary outcome was proteomic changes compared between normal (≥preoperative value before induction of anaesthesia) and low DO2 (

Does Participative Leadership Matters in Employees' Outcomes During COVID-19? Role of Leader Behavioral Integrity.

The coronavirus pandemic (COVID-19) has badly affected the social, physical, and emotional health of workers, especially those working in the healthcare sectors. Drawing on social exchange theory, we investigated the effects of participative leadership on employees' workplace thriving and helping behaviors among frontline workers during the COVID-19 pandemic. In addition, we examined the moderating role of a leader's behavioral integrity in strengthening the relationship between participative leadership, and employees' workplace thriving and helping behaviors. By using a two-wave time-lagged design and data collected from 244 healthcare workers, a moderated hierarchal regression was implemented to test the proposed hypotheses. As hypothesized, participative leadership predicted employees' workplace thriving and helping behaviors. The leader's behavioral integrity strengthened the relationship between participative leadership and employees' thriving and moderated the relationship between participative leadership helping behaviors. Implications for research, theory, and practice are discussed.

Deep learning-based photoplethysmography classification for peripheral arterial disease detection: a proof-of-concept study.

Objective.A proof-of-concept study to assess the potential of a deep learning (DL) based photoplethysmography PPG ('DLPPG') classification method to detect peripheral arterial disease (PAD) using toe PPG signals.Approach.PPG spectrogram images derived from our previously published multi-site PPG datasets (214 participants; 31.3% legs with PAD by ankle brachial pressure index (ABPI)) were input into a pretrained 8-layer (five convolutional layers + three fully connected layers) AlexNet as tailored to the 2-class problem with transfer learning to fine tune the convolutional neural network (CNN).k-fold random cross validation (CV) was performed (fork = 5 andk = 10), with each evaluated over k training/validation runs. Overall test sensitivity, specificity, accuracy, and Cohen's Kappa statistic with 95% confidence interval ranges were calculated and compared, as well as sensitivities in detecting mild-moderate (0.5 ≤ ABPI < 0.9) and major (ABPI < 0.5) levels of PAD.Main results.CV with eitherk = 5 or 10 folds gave similar diagnostic performances. The overall test sensitivity was 86.6%, specificity 90.2% and accuracy 88.9% (Kappa: 0.76 [0.70-0.82]) (atk= 5). The sensitivity to mild-moderate disease was 83.0% (75.5%-88.9%) and to major disease was 100.0% (90.5%-100.0%).Significance.Substantial agreements have been demonstrated between the DL-based PPG classification technique and the ABPI PAD diagnostic reference. This novel automatic approach, requiring minimal pre-processing of the pulse waveforms before PPG trace classification, could offer significant benefits for the diagnosis of PAD in a variety of clinical settings where low-cost, portable and easy-to-use diagnostics are desirable.

Exploring the Effect of Metformin to Lower Thyroid-Stimulating Hormone in Euthyroid and Hypothyroid Type-2 Diabetic Patients.

Introduction Metformin is one of the safest, first-line oral hypoglycemic agents used in type-2 diabetes mellitus patients. This study aims to study the effect of metformin on thyroid-stimulating hormone (TSH) in hypothyroid and euthyroid individuals, as both these diseases have an increased prevalence and coexistence. Method This hospital-based study was conducted in Jinnah Allama Iqbal Institute of Diabetes and Endocrinology (JAIDE), Allama Iqbal Medical College/Jinnah Hospital Lahore, Pakistan, from October 2019 to April 2020. One hundred and sixty type-2 diabetic participants, aged 25-60 years and meeting the inclusion criteria were enrolled in the study after informed consent. They were divided into two groups, the hypothyroid group who were already on levothyroxine therapy and had a stable TSH in the normal range, and a euthyroid group who had no thyroid dysfunction. Both the groups were started on metformin therapy for the control of type-2 diabetes mellitus and followed for six months. Their blood samples for TSH and free thyroid hormone (fT4) were drawn both prior to and after the study period. Results Out of the 160 type-2 diabetic patients, TSH levels showed a significant reduction in the hypothyroid patients (2.33 ± 0.70, p < 0.001) with no significant changes in the euthyroid patients (3.87 ± 0.40, p = 0.206) following six months of metformin therapy. However, there was no significant difference in the fT4 levels in either of the groups. Conclusion Metformin has the effect of significantly lowering TSH levels in hypothyroid individuals. However, no such effect was observed in euthyroid patients.

The Impact of Authentic Leadership on Organizational Citizenship Behaviors: The Mediating Role of Affective- and Cognitive-Based Trust.

Authentic leadership has appeared as a significant field of research. Building on social exchange theory that explicates how individuals mutually mechanize reciprocation and eventually establish a trust-based relationship, we postulated a positive relationship between authentic leadership and followers' organizational citizenship behaviors (OCBs). Based on a two-wave time lagged design, the data were obtained from 270 employees working in a private banking sector of Pakistan. We found that authentic leadership is positively associated with subordinate's OCBs, as well as leads to a higher-level of both affective- and cognitive-based followers' trust. The results also indicated that both affective- and cognitive-based trust positively mediated the relationship between authentic leadership and OCBs. The implications for theory and practice are discussed.

Outcomes of Harmonic Scalpel and Electrocautery in Patients Who Underwent Modified Radical Mastectomy.

Objective This study aimed to compare the mean operative time, total analgesic required, and the mean number of drainage days in harmonic scalpel versus electrocautery in breast cancer patients undergoing modified radical mastectomy (MRM). Methodology This retrospective cross-sectional study was conducted in the Department of General Surgery, Jinnah Postgraduate Medical Center (JPMC). The duration of the study was six months, from January 2018 until July 2018. A total of 194 females with biopsy-proven breast cancer undergoing MRM were included in the study. They were divided into two groups. In group 'A', a harmonic scalpel was used, and in group 'B', electrocautery was used for hemostasis. Results The mean age of the participants was 48.68 ±10.04 years. The mean operative time was 102.13 ±2.04 minutes. The mean number of days of drainage was 1.27 ±2.63. The mean analgesia amount was 30.72 ±3.25 mg. In the harmonic scalpel group, the mean operative time was 100.43 ±0.89 minutes, whereas, in the electrocautery group, it was 103.86 ±1.12 minutes with a significant difference (p=0.001). In the harmonic scalpel group, the mean number of drainage days was 8.90 ±0.42, whereas, in the electrocautery group, it was 13.58 ±1.26 with a statistically significant difference (p=0.001). In the harmonic scalpel group, the mean analgesia amount was 1,800.5 ±353.55 mg, whereas, in the electrocautery group, it was noted to be 2,006.25 ±289.43 with a statistically significant difference (p=0.001). Conclusion This study concludes that compared with standard electrocautery, harmonic scalpel dissection is associated with significant benefits in decreasing postoperative drainage and blood loss during operations after MRM for breast cancer.

Synthesis, lipoxygenase inhibition activity and molecular docking of oxamide derivative.

In this study, a range of oxamide ligands were synthesized by the reaction of amines with oxalyl chloride in basic medium. Spectroscopic and analytical techniques such as IR, 1H-NMR and ESI-MS techniques were used for characterization of the synthesized oxamides. The synthesized oxamides were screened for Lipoxygenase inhibition. Biological screening revealed that the oxamides possessed good lipoxygenase inhibition activities, whereas, the unsubstituted oxamide did not show any distinct lipoxygenase inhibition activity. Molecular docking studies of the oxamides were also carried out for lipoxygenase inhibition. The results obtained from molecular docking were well correlated with the empirical data.

Employees' Perceptions of CSR, Work Engagement, and Organizational Citizenship Behavior: The Mediating Effects of Organizational Justice.

Corporate social responsibility (CSR) at the individual level has emerged as an important field of research. However, a more comprehensive understanding of how CSR affects employee work engagement and organizational citizenship behavior (OCB) is still lacking. Based on social exchange theory, we examine the effects of employees' perceptions of CSR on OCB and work engagement as well as the mediating mechanism of distributive and procedural justice, based on data collected from 350 employees working in the banking sector of Pakistan. Our study suggests that employees' perceptions of CSR positively predict OCB and work engagement, and that work engagement is positively related to OCB. Both distributive and procedural justice positively mediate the effects of employees' perceptions of CSR on OCB and work engagement.

Bridging the Gap between Authentic Leadership and Employees Communal Relationships through Trust.

Authentic leadership has emerged as a positive relational-leadership approach that has gained the attention of academicians and practitioners by stimulating a healthy work environment. This study examined the direct influence of authentic leadership on employees' communal relationships. In addition, the study examined the mediating role of affective- and cognitive-based trust on these relationships. We adopted a cross-sectional study design and collected data from 200 employees working in the private banking sector in Pakistan. The findings indicated that authentic leadership was positively correlated with communal employee relationships. In addition, both affective- and cognitive-based trust were found to have a positive mediating effect on the relationship between authentic leadership and communal employee relationships. The practical implications, limitations and suggestions for future research are discussed.

Cultivating employees' communal relationship and organizational citizenship behavior through authentic leadership: studying the influence of procedural justice.

BACKGROUND: Leaders play vital role in organization to accomplish organizational goals and establish healthy working environment. This study addresses the effect of authentic leadership on employees' communal relationship and organizational citizenship behavior (OCB). In addition, this research also examines how procedural justice augments the effect of authentic leadership on both aforementioned employees' behavioral outcomes. MATERIALS AND METHODS: Using a cross-sectional design, data were collected from 425 employees working in banking sector of Pakistan. It was hypothesized that authentic leadership would positively predict employees' communal relationship and OCB. Furthermore, we also assumed that procedural justice will strengthen the relationship between authentic leadership, both behavioral outcomes, that is, employees' communal relationship and OCB. RESULTS: Analyses reveal that authentic leadership positively predicts employees' communal relationship and OCB. In addition, procedural justice was found to positively moderate the effect of authentic leadership on employees' communal relationship and OCB. CONCLUSION: To our knowledge, this is the first study to investigate the relationships among authentic leadership, procedural justice, communal relationship, and OCBs in the South Asian context. This is the first study to report the moderating role of procedural justice in the relationship between authentic leadership and communal relationship and OCB. The practical implications of study findings and direction for future research are discussed.
