RESUMO
Molecular disease subtype discovery from omics data is an important research problem in precision medicine. The biggest challenges are the skewed distribution and data variability in the measurements of omics data. These challenges complicate the efficient identification of molecular disease subtypes defined by clinical differences, such as survival. Existing approaches adopt kernels to construct patient similarity graphs from each view through pairwise matching. However, the distance functions used in kernels are unable to utilize the potentially critical information of extreme values and data variability which leads to the lack of robustness. In this paper, a novel robust distance metric (ROMDEX) is proposed to construct similarity graphs for molecular disease subtypes from omics data, which is able to address the data variability and extreme values challenges. The proposed approach is validated on multiple TCGA cancer datasets, and the results are compared with multiple baseline disease subtyping methods. The evaluation of results is based on Kaplan-Meier survival time analysis, which is validated using statistical tests e.g, Cox-proportional hazard (Cox p-value). We reject the null hypothesis that the cohorts have the same hazard, for the P-values less than 0.05. The proposed approach achieved best P-values of 0.00181, 0.00171, and 0.00758 for Gene Expression, DNA Methylation, and MicroRNA data respectively, which shows significant difference in survival between the cohorts. In the results, the proposed approach outperformed the existing state-of-the-art (MRGC, PINS, SNF, Consensus Clustering and Icluster+) disease subtyping approaches on various individual disease views of multiple TCGA datasets.

Five examples of unsymmetrical 2-(2,4-bis(dibenzocycloheptyl)-6-methylphenyl- imino)ethyl)-6-(1-(arylyimino)ethyl)pyridine derivatives (aryl = 2,6-Me2C6H3 in L1; 2,6-Et2C6H3 in L2; 2,6-i-Pr2C6H3 in L3; 2,4,6-Me3C6H2 in L4 and 2,6-Et2-4-MeC6H2 in L5) were prepared and characterized. Treatment with CoCl2 offered the corresponding cobalt precatalysts Co1-Co5, which were characterized by FT-IR and NMR spectroscopy as well as elemental analysis. The molecular structures of Co3 and Co4 determined by single crystal X-ray diffraction revealed distorted square pyramidal geometries with τ5 values of 0.052-0.215. Activated with either MAO or MMAO, the precatalysts displayed high activities in ethylene polymerization, where Co1 with the least bulky substituents exhibited a peak activity of 1.00 × 107 g PE mol-1 (Co) h-1 at 60 °C. With MAO as a cocatalyst, the activity was reduced only by one order of magnitude at 90 °C, which implies thermally stable active sites. The polymerization product was highly linear polyethylene with vinyl end groups. Co3 with the most sterically hindered active sites was capable of generating polyethylene of high molecular weight, reaching 6.46 × 105 g mol-1. Furthermore, high melting point and unimodal molecular weight distribution were observed in the resulting polyethylene. It must be stressed that the thermal stability of the catalyst and the molecular weight of the obtained polyethylene attain the highest values reported for the unsymmetrical 2,6-bis(imino)pyridylcobalt (II) chloride precatalysts.

This study examines the effect of gamification on workplace thriving and employee well-being in the hospitality and tourism organizations, investigating the mediating effects of conflict resolution and working relationships while assessing the moderating influence of top management support. We conducted a time-lagged study with 451 employees from various hospitality and tourism organizations. Our research aimed to understand how gamification affects workplace thriving and employee well-being, with a focus on the mediating roles of conflict resolution and working relationships. We also examined the moderating effect of top management support. Our results demonstrate a positive link between gamification and workplace thriving, as well as a connection between gamification and employee well-being. Conflict resolution was found to mediate the relationship between gamification and workplace thriving, while working relationships mediated the connection between gamification and employee well-being. Additionally, top management support significantly moderated the relationships between gamification, conflict resolution, and workplace thriving.

After the UN Climate Action Summit in 2019, many countries started progressing towards race to zero targets. The intricate framework of digitalization and green technologies has the potential to persuade governments to implement policies that promote a zero-carbon economy, i.e., green economy. Hence, this study determines the effect of digital trade (DGT) and green technological innovation (GTI) on environmental sustainability (ENS) by considering the role of renewable energy consumption (REC), globalization (GLOB), and economic growth (EG). The study measured ENS by taking into account three proxy variables, i.e., ecological footprint (EF), carbon dioxide emission (CO2e), and methane emissions (CH4e). POLS and PMG-ARDL techniques are applied to the panel data of BRICS (Brazil, Russia, India, China, and South Africa) from 2000 to 2019. Panel Quantile Regression (PQR) along with AMG and CCEMG estimators is applied hereafter for checking the robustness of the empirical results. The long-run empirical outcomes show the positive association of DGT, GTI, REC, and GLOB with ENS. Lastly, this study inscribed the Environmental Kuznets Curve (EKC) and highlights policy implications and governmental measures to ensure environmental sustainability in BRICS economies.

The study intends to investigate the impact of servant leadership on pro-social rule-breaking directly and through the intervening mechanism of psychological safety. More, the study also plans to investigate whether compassion at work moderates the effect of servant leadership on psychological safety and pro-social rule-breaking and the indirect intervening effect of psychological safety between servant leadership and pro-social rule-breaking. Responses were collected from 273 frontline public servants in Pakistan. Using social information processing theory, the results revealed that servant leadership positively influences pro-social rule-breaking and psychological safety and that psychological safety influences pro-social rule-breaking. Results also revealed that psychological safety acts as an intervening mechanism in the relationship between servant leadership and pro-social rule-breaking. Moreover, compassion at work significantly moderates the relationships of servant leadership with psychological safety and pro-social rule-breaking, and that compassion at work ultimately alters the size of the intervening effect of psychological safety between the connection of servant leadership and pro-social rule-breaking.

Purpose: This study investigates the association between the previous workplace ostracism of employees and their subsequent helping behavior by drawing on moral cleansing theory in the Chinese context, exploring the mediating roles of employees' guilt and perceived loss of moral credit and the moderating role of their moral identity symbolization. Sample and Method: The data were collected from a two-stage time-lagged survey of 284 Chinese employees. Regression analysis and the bootstrapping method are used in this article to examine the theoretical hypotheses. Results: The results indicate that employees' previous ostracism behaviors positively affected their guilt experience and perceived loss of moral credit. Subsequently, the relationship between employees' workplace ostracism and their helping behavior is mediated by guilt experience and perceived loss of moral credit. Furthermore, moral identity symbolization positively moderated the indirect "workplace ostracism-helping behavior" linkage via guilt and perceived loss of moral credits; in other words, for employees who have a higher degree of moral identity symbolization, the mediating effect is more significant, and vice versa. Conclusion: This study does not merely clarify the theoretical relationship between perpetrators' workplace ostracism and their helping behavior, which enriches the explanatory logic of related research on workplace ostracism and the cause of helping behavior, but also expand the application scope of moral cleansing theory. Further, we aim practically to bring enlightenment to human resource management reform, corporate culture construction, and positive behavior management.
RESUMO
Objective: Grounding on social learning theory (SLT), this study examines the effect of public leadership on project management effectiveness (PME). Further, this study examines the mediating role of goal clarity and moderating role of top management support. Methodology: Hierarchical linear regressions were used to investigate the relationships. PROCESS Hayes (2003) Model 7 was used for the moderation and mediation analysis. The data was collected from 322 Pakistani public sector developmental project employees. Findings: The results show that public leadership positively affects goal clarity (ß = 0.049, p < 0.001) and project management effectiveness (0.032, p < 0.001). In addition, goal clarity mediates the association between public leadership and project management effectiveness (0.36, p < 0.001). Furthermore, the strength of the mediated relationship between public leadership and project management effectiveness (via goal clarity) depends on top management support. The indirect effect of public leadership on project management effectiveness is high when top management support is high (compared to low). Conclusion: The role of public leadership contributes significantly to the project's success. The project leader recognises, enlists, and promotes the organisation's core competencies, identifies, corrects, and controls key rigidities, places a high value on goal clarity, and continually lines up procedures with the project's overarching goals. Implications: Public leadership is crucial in project management effectiveness, especially in the public sector, where projects often involve multiple stakeholders, limited resources, and complex regulatory requirements. Effective public leadership ensures that projects are aligned with the organization's mission and goals and carried out efficiently, on time, and within budget.
RESUMO
An elegant solution for the concurrent transmission of data and power is essential for implantable wireless magnetic resonance imaging (MRI). This paper presents a self-tuned open interior microcoil (MC) antenna with three useful operating bands of 300 (7 T), 400, and 920 MHz, for blood vessel imaging, data telemetry, and efficient wireless transmission of power, respectively. The proposed open interior MC antenna contains two mirrorlike arms with diameters and lengths of 2.4 mm and 9.8 mm, respectively, to avoid blood flow blockage. To wirelessly show LED glow on a saline based phantom, the MC was fabricated on a flexible polyimide material and combined with a miniaturized rectifier and a micro-LED. Using a path gain, the power transfer efficiency (PTE) of the MC rotation was also analyzed. Additionally, the PTE was calculated for a range of distances between 25 and 60 mm, and a -27.1 dB PTE attained at a distance of of 30 mm. Based on the recommendations of the International Commission on Non-Ionizing Radiation Protection for human brain safety when exposed to radio-frequencies from external transmitter, a specific absorption rate analysis was analyzed. Measurements of the s-parameters were noted using a saline solution and blood vessel model to imitate a realistic human head. They were found to correlate reasonably with the simulated results.

Grounding on social exchange theory and using the creative process engagement as a lens, this article study investigates the influence of servant leadership on employee creativity. In addition, the research examines the role of knowledge sharing in the link between servant leadership and employee creativity. Time lag method was used to collect the data from 242 employees and 57 managers employed in Chinese publicly listed companies. The data collection was divided into two parts. The subordinates were asked to rate servant leadership, their creative process engagement behavior, and knowledge sharing. The supervisors were asked to rate their associates regarding employee creativity. According to the results, employees creative process engagement behaviors mediated servant leadership and employees' creativity. In addition, the link between servant leadership and employees' creativity was strengthened by knowledge sharing. A detailed model is also provided, highlighting the significance of leadership, work engagement, knowledge sharing in fostering employee creativity in the Asian environment.
RESUMO
The COVID-19 pandemic has caused a record global crisis, particularly and extremely, for the service sectors. Due to extensive security measures, many service sector employees have to work remotely to maintain services. Drawing upon the conservation of resources theory, this research investigates the impact of servant leadership on the task performance of employees in virtual working environments during the COVID-19 crisis. Our theoretical model was tested using data collected from 335 individual employees in the education sector of Pakistan. SPSS version 26.0 was applied to find the hypothesized relationship between the study variables. To find the indirect mediating effect, we applied Model 4; for moderation, we applied Model 1; and for the moderation and mediation effect, we applied Model 7 of the Process Macro model of Hayes. The results of the study revealed that servant leadership is positively related to task performance in a virtual environment during crises. Furthermore, psychological empowerment partially mediates the relationship between servant leadership and task performance. Perceived supervisor support positively moderates the relationship between servant leadership and task performance. Moreover, the indirect effect of servant leadership on task performance via psychological empowerment is moderated by perceived supervisor support. The results provided guidance to the educational sector on how to lead effectively in times of crisis when service sector employees work predominantly in virtual environments. The theoretical and practical implications of these findings are discussed.
RESUMO
This study examined (1) the influence of ethical leadership on knowledge sharing, (2) the mediating role of psychological ownership, and (3) the moderating effect of professional commitment between ethical leadership (EL) and knowledge sharing (KS). Data were collected from 307 public listed Pakistani companies' employees. Statistical analyses were performed by using SPSS Version 25 and AMOS version 22. The findings indicate a positive relationship between EL and KS behavior. Additionally, the impact of EL on KS was partially mediated by psychological ownership. Furthermore, professional commitment buffers the link between EL and KS. This study contributes to the body of knowledge in the field of leadership by confirming the role of ethics. The results show that ethical leaders develop employee attitudes (i.e., psychological ownership and professional commitment) that contribute to employee KS behavior. Ethical leaders create and encourage a learning culture to enhance organizational performance. This study adds to the little data on the positive impact of EL on listed company's employees and addresses the gaps in previous studies on the role of EL in changing environments. In addition, professional commitment as a moderator has not been previously investigated with ethical leadership antecedents.
RESUMO
PURPOSE: Spiritual inherited employees quickly shift to new changes that occur very quickly in our daily lives in different ways. We are inspired by the dynamic changes in our daily lives due to the Covid 19 situation, an urgent need to specify the shift from the traditional approach to the agile approach during a pandemic. This study aimed to figure out the effect of workplace spirituality on workforce agility; further, this study underpinning spillover theory to examine the role of job involvement as a mediator. METHODS: This study investigates a sample of 236 teaching and administrative staff working in public sector institutes located in Peshawar, Pakistan. For data analysis, we used SPSS v. 25, and for model fitness, we used AMOS version 22. Furthermore, we used Process Hayes (Model 4) to test the theoretical model and research hypothesis for mediation. RESULTS: This unique study offers a paradigm in which spirituality in the workplace substantially influences the agility of teaching and administrative professionals by positively mediating the effects of job involvement. DISCUSSION: An in-depth examination of the literature showed that no prior research had studied the connection between WPS, job involvement, and workforce agility. Furthermore, there is very little research regarding WPS and its connection with other components in the Covid 19 scenario. The current study was a modest attempt to address this gap in the literature. This research has succeeded in making substantial additions to management literature.

RESUMO
This study aims to empirically examine the mediating effects of psychological safety and leadership identification on the relationship between inclusive leadership and pro-social rule breaking among hospitality employees. This study analyzes the survey data collected in three waves from 589 employees working in different hotels and restaurants operating in the Northern areas of Khyber Pakhtunkhwa, Pakistan. The scale validity, composite reliability, and hypotheses were assessed through PLS-SEM. The study found that inclusive leadership significantly impacts employees' pro-social rule-breaking. The study also found that leadership identification and psychological safety partially mediate the relationship between inclusive leadership and pro-social rule-breaking. Hospitality leaders can practice inclusive leadership characteristics because it may significantly enhance employee engagement in pro-social rule-breaking. Through their inclusive features, hospitality leaders can improve employees' psychological safety and leadership identification, enhancing frontline employees' pro-social rule-breaking.

This research explores the effect of servant leadership on prosocial rule-breaking (PSRB) and the mediating mechanism of public service motivation (PSM) between the association of servant leadership and PSRB. The said phenomenon is examined in the civil service context of Pakistan during the continuing crises of the COVID-19 pandemic, a situation where the traditional civil service policy and rule system has become highly complicated for passionate employees' service performance and efficiency, and where servant leadership has received greater attention for inspiring the attitudinal and behavioral outcomes of frontline workers during the pandemic. Data were collected from 546 frontline workers of the corona relief tiger force. The findings of the study revealed that servant leadership has a significant effect on PSRB and PSM, and that PSM significantly promotes PSRB. The results also revealed that servant leadership has a significant impact on PSRB via engendering PSM.
RESUMO
Decision making is an essentially social process adopted by individuals or groups to identify and choose the best choice among several alternatives. Decision-making choices are influenced by the preferences, values, and beliefs of the individuals or groups involved in the decision-making process. This study was conducted to analyze the social inclusion of Persons with Disabilities (PWDs) in the context of their participation in decision making. The study area consisted of 8028 PWDs registered with the government of Pakistan, from which a sample of 488 PWDs was selected through a multistage stratified random sampling technique. These PWDs included physically disabled, blind, crippled, and deaf persons; however, the data were collected from those who were able to be interviewed. Chi-square and Kendall's Tau-b tests were used to determine the strength, level, and direction of association among variables. At the multivariate level, the study found a spurious relation between social inclusion and participation in decision making when controlling for gender, monthly family income, and level of disability of the PWDs. The results highlighted that participation in decision making improved the social inclusion of male and moderately disabled PWDs more positively. However, participation in decision making was a universal feature explaining the social inclusion of PWDs irrespective of their monthly family income. The logistic regression model explained that the social inclusion of PWDs was more likely to occur when PWDs were married, had high monthly family income (PKR 16,500 and above), belonged to a joint family, and actively participated in decision making. The study recommends that ensuring the participation of PWDs in decision making in family, community, school, and other relevant institutions ultimately enhances their social inclusion.

Whistleblowers who expose wrongdoing often face several concerns, pressures, and threats of retaliation before reaching a final decision. Specifically, this study examines the effects of perceived seriousness of wrongdoing (PSW) and perceived threat of retaliation (PTR), as well as the impact of rationalization (RNL), comparing perceived seriousness of wrongdoing, perceived threat of retaliation and whistleblowing intention. Furthermore, this study aims to determine the mediating effect of anticipated regret (AR) on the relationship between perceived seriousness of wrongdoing and whistleblowing intention. We validated our model by analyzing data gathered across three stages from employees in the telecom sector in Pakistan. The key findings of our research may be summarized as follows: (i) individuals' willingness to 'blow the whistle' increases as a result of perceived seriousness of wrongdoing; (ii) whistleblowers are more likely to opt to remain silent if they anticipate a greater threat of retaliation, and (iii) our study establishes a positive connection between perceived seriousness of wrongdoing and whistleblowing intention, indicating that perceived seriousness of wrongdoing enhances people's willingness to blow the whistle, and whistleblowers are more likely to choose to emerge if the behaviour is more serious in nature; (iv) the data we have uncovered indicates a moderating role of rationalization in regulating the connections between perceived seriousness of wrongdoing, perceived threat of retaliation, and whistleblowing intention; and (v) the findings demonstrate that anticipated regret mediates the connection between perceived seriousness of wrongdoing and the intention to report wrongdoing. Additionally, the results are discussed in terms of their significance for corporate ethics researchers and managers, as well as for end-users who are interested in whistleblowing.

The fourth industrial revolution will be ushered in by future high technology, and as a result, the world will face new difficulties relating to people, the environment, and profitability. Accordingly, the competitive edge and long-term viability of businesses would depend on the knowledge workers who could overcome these excruciatingly difficult obstacles and have the knowledge and competency to influence the overall performance of any type of company. But managing knowledge workers falls under the purview of human resources, and only effective human resources tools, plans, and procedures can ensure the success of this task. One such tool, which has the capacity and capability to change the whole scenario in an organization's favor, is the human resource information system (HRIS). The purpose of this structured review is to provide insight into a field of HRM (i.e., HRIS) that has largely been neglected by other reviews of the literature and has only been briefly discussed by a small number of publications published in reputable, top-tier journals. A customized HRIS framework is the result of this structured literature review for managing knowledge and competence. The study presents the content analysis of 48 articles, systematically and purposefully selected for this literature review, published during the past three decades. The study has several implications for policymakers and HR practitioners.
RESUMO
This study examines the impact of negative workplace gossip (NWG) on employee political acts (PA) and the role of ego depletion (ED) as a mediator. We also examined the indirect impact of NWG on PA through ED controlled by emotional intelligence (EI). A three-wave time-lagged study (paper-pencil based) was performed with 277 employees from various private organisations in Islamabad, Pakistan. The current data were gathered in three phases to reduce common method bias. Study results indicate that NWG positively affects employees' PA. The authors also found ED as a potential mediator in the association between NWG and PA. In addition, the results also indicate the indirect effect of NWG on targets' PA via ED is reduced by targets' EI, with the result that this connection is weak when targets' EI is high. Because this research is limited to a single region of Pakistan, particularly Islamabad, its findings cannot be comprehensive. Future studies should use a larger sample size to accomplish the same study. Future studies may include more organisations (that is, Public) to conduct a comparative analysis of the public and private sectors. This article, based on the affective events theory (AET), argues that EI should be utilised to mitigate the effects of NWG. Along with our significant and relevant theoretical contributions, we provide novel insights into the body of knowledge on how managers may prevent or minimise such PA. The current study results support all direct and indirect hypothesised connections, with important implications for theory and practice. A review of the existing literature indicates that EI may be associated with a reduction in employees' ED; however, EI has not been used as a moderator in mitigating the influence of NWG, ED, and PA in the past.

The application of traceability technology is an important way to solve food safety problems. Different traceability technologies bring different effects to consumers. Existing studies have not explored consumers' preferences in regards to product traceability technology applications, and they have not analyzed their willingness to pay. Therefore, this study focused on organic rice, an ecological agricultural product. The study was based on a survey from Jiangxi Province, China. It used a selective experiment method in order to analyze consumer preferences and the willingness to pay for ecological agricultural product traceability technology. The results show that consumer preferences are as follows: blockchain technology application attributes, traditional traceability-technology-application attributes, high credit-supervision attributes, and international-certification attributes. In terms of willingness to pay, consumers have the highest willingness to pay for the application of blockchain technology, which they are willing to pay CNY 21.902 more per kg for this attribute. At the same time, consumers are also willing to make additional payments for traditional traceability-technology-application attributes, high credit-supervision attributes, and international-certification attributes. Their willingness to pay is CNY 20.426, CNY 17.115 yuan, and CNY 11.049, respectively.
