Organizational politics has been a topic of conceptual and empirical interest for researchers and practitioners for many years. The purpose of this paper is to examine the relationship between organizational politics and employee work outcomes in educational institutions. In addition, this paper also aims to assess the moderating role of social capital.

Employee perceptions about organizational politics and its impact on their work outcomes have been assessed empirically with a sample of 270 full-time employees in higher education institutions of Pakistan. The data have been collected from faculty members of five universities of Pakistan using survey method. SPSS and AMOS have been used to analyze the data and SEM has been used to test the hypotheses.

The results indicate a moderating effect of social capital on the relationship between perceived organizational politics and employee outcomes, and the most significant employee outcomes are job stress, job satisfaction and turnover intentions. The findings of the study support the view that organizational politics has negative association with employee job stress and turnover intentions.

Higher education sector in Pakistan is facing certain challenges, which affect talent retention. The findings of this study will help the administration of higher education institutions to develop effective strategies to cope with the challenges of organizational politics, such as motivation, satisfaction and retention of their employees.

The study adds to the literature on organizational politics by highlighting and validating its adverse effects on employee work outcomes in the context of Pakistani higher education.

Composite materials are effective alternatives for rehabilitating critical members of offshore platforms, bridges, and other structures. The structural response of composite reinforcement greatly depends on the orientation of fibres in the composite material. Joints are the most critical part of tubular structures. Various existing studies have identified optimal reinforcement orientations for a single load component, but none has addressed the combined load case, even though most practical loads are multiplanar.

This study investigates the optimal orientation of composite reinforcement for reducing stress concentration factors (SCF) of tubular KT-joints. The joint reinforcement was modelled and simulated using ANSYS. A parametric study was carried out to determine the effect of the orientations of reinforcement in the interface region on SCF at every 15° offset along the weld toe using linear extrapolation of principal stresses. The impact of orientation for uniplanar and multiplanar loads was investigated, and a general result about optimum orientation was inferred.

It was found that the maximum decrease of SCF is achieved by orienting the fibres of composite reinforcement along the maximum SCF. Notably, the optimal direction for any load configuration was consistently orthogonal to the weld toe of the chord-brace interface. As such, unidirectional composites wrapped around the brace axis, covering both sides of the brace-chord interface, are most effective for SCF reduction.

The findings of this study are crucial for adequate reinforcement of tubular joints using composites, offering a broader and universally applicable optimum orientation that transcends specific joint and load configuration.

This study examines the relationship between employees' perceptions of informational fairness and project performance. Furthermore, it examines if this relationship is sequentially mediated by (1) knowledge sharing and role clarity and (2) communication openness and role clarity.

Data are collected from 302 full-time employees of seven project-based construction organizations in Pakistan. Data are analyzed through variance-based structural equation modeling technique and the Preacher and Hayes' bootstrapping procedure.

Results indicate that project employees' perceptions of informational fairness positively predict project performance. Moreover, this relationship is sequentially mediated by (1) communication openness and role clarity and (2) knowledge sharing and role clarity.

This study provides further insights on the informational fairness and project performance relationship by examining their underlying mechanisms. It draws on the much ignored context of Pakistan, and offers some implications for managers and researchers with regard to how behavioral factors may further enhance project performance.

This paper aims to develop a fuzzy logic-based algorithm to predict the intermetallic compound (IMC) size and mechanical properties of soldering material, Sn96.5-Ag3.0-Cu0.5 (SAC305) alloy, at different levels of temperature. The reliability of solder joint in materials selection is critical in terms of temperature, mechanical properties and environmental aspects. Owing to a wide range of soldering materials available, the selection space finds a fuzzy characteristic.

The developed algorithm takes thermal aging temperature for SAC305 alloy as input and converts it into fuzzy domain. These fuzzified values are then subjected to a fuzzy rule base, where a set of rules determines the IMC size and mechanical properties, such as yield strength (YS) and ultimate tensile strength (UTS) of SAC305 alloy. The algorithm is successfully simulated for various input thermal aging temperatures. To analyze and validate the developed algorithm, an SAC305 lead (Pb)-free solder alloy is developed and thermally aged at 40, 60 and 100°C temperature.

The experimental results indicate an average IMCs size of 5.967 (in Pixels), 19.850 N/mm² YS and 22.740 N/mm² UTS for SAC305 alloy when thermally aged at an elevated temperature of 140°C. In comparison, the simulation results predicted 5.895 (in Pixels) average IMCs size, 19.875 N/mm² YS and 22.480 N/mm² UTS for SAC305 alloy at 140°C thermally aged temperature.

From the experimental and simulated results, it is evident that the fuzzy-based developed algorithm can be used effectively to predict the IMCs size and mechanical properties of SAC305 at various aging temperatures, for the first time.

The purpose of this paper is to investigate the occurrence of rating distortions under raters’ different mood conditions and at different levels of interpersonal affect of raters towards ratees, and further its association with ratees’ perceptions of distributive and interpersonal fairness.

For the scenario-based experiment, the study recruited 110 undergraduate students as participants. Of them, 22 raters appraised the video-taped buyer-seller negotiation performance of 88 ratees. Repeated measures analysis was employed to analyse data.

Results revealed that under different mood conditions (pleasant and sad) and at different levels of interpersonal affect towards ratees (high and low), raters distorted ratings (inflated and deflated, respectively). These rating distortions shaped ratees fairness perceptions in such a way that ratees who received inflated ratings due to raters’ pleasant mood and high interpersonal affect perceived more distributive and interpersonal fairness than ratees who received deflated ratings due to raters’ sad mood and low interpersonal affect.

The paper is a step towards integrating the affect infusion model with distributive and interpersonal fairness theory. This integration can be of value for enhancing our understanding of how rater-centric rating errors take place, which subsequently shape ratees’ fairness perceptions.

Recent performance appraisal (PA) literature suggests that alongside cognitive biases, rating distortions may stem from rater disposition and PA context. The study investigated the role of social value orientation (rater disposition), PA purposes and rater accountability (PA context) toward rating distortions at both performance levels, i.e. good and poor.

The authors designed an experimental study and elicited data from N = 110 undergraduate students about two video-taped performances of good and poor performers. In these videos, two managers conducted assessment interviews of two different employees for the job of a sales representative at an information technology organization. To ensure the validity of performance ratings, the authors invited 10 senior managers to provide benchmark ratings of the video-taped performances. While being placed in two separate groups, the study participants gave performance ratings on both the video-taped performances. The authors used repeated-measures analysis to analyze data.

The results revealed that rating distortions took place not because of rater social value orientation, but the PA context. Different rating distortion patterns emerged for different levels of ratees' performance.

This study’s findings furnish new insights for assessing rating distortions for poor as well as good performers. Moreover, the results support previous findings that for good performers, accountable raters are tempted toward accurate ratings and refrained from deflation. Similarly, for poor performers, accountable raters do not inflate ratings. The findings will open research avenues to examine the role of PA purposes in rating distortions for different performance levels.

This study seeks to examine the links between employee agreeableness, group performance, and peers' perceptions of threat of retaliation, through relationship conflict.

In a laboratory setting, 42 groups of undergraduate students (N = 182) from a Pakistani university were assigned to group projects to be completed within four months. Data collected from three different questionnaires at four different times and actual scores awarded by the course instructor to each group were used for the analyses. Based on r_WG(J) and ICC(1), level 1 (182 students') data were aggregated to level 2 (groups), and then analysed using regression analysis followed by Preacher and Hayes' bootstrapping procedure.

Results suggest that high agreeableness predicts group performance positively and peers' perceptions of threat of retaliation negatively. Moreover, relationship conflict among group members significantly mediates the agreeableness-group performance relationship. The above relationships may be sensitive to national culture.

In this study, groups were formed for a few months, whereas in real organizational life, workgroups are formed for different durations. Therefore, the range of situations to which these findings generalize remains an open question.

Agreeableness of group members can be constructive for performance of the group. Managers may utilize this insight while forming groups, and rating performance.

There is dearth of research illuminating how employee's personality traits affect group performance and appraisal ratings. The study tests the effects of employee agreeableness on: (1) group performance, as rated by supervisors; (2) the threat of retaliation, as perceived by peer raters; and (3) the mediating effect of relationship conflict.

While studying the association between leader–member exchange (LMX) quality and employee work outcomes, the existing scholarship has generally focused on employee perspectives of LMX quality. Being more inclusive, this study utilizes role theory to incorporate the dyadic (in)congruence in LMX quality and their effects on ratee feedback seeking behavior.

Data elicited from N = 156 matched rater–ratee dyads comprising engineers working with telecommunication organizations of Pakistan. Purposive sampling was done to ensure that rater–ratee dyads were in continuous contact by their customized employee portals.

Results of polynomial regression analysis revealed that leader–member congruence in their perceptions of LMX quality enhanced member's feedback seeking behavior. Asymmetrical incongruence, i.e. the member perceived higher LMX quality than the leader, is found to predict member's feedback seeking behavior, even higher than both levels of congruence (high- and low-quality LMX).

The scope of this study was members' reactions to performance appraisal. However, other performance appraisal outcomes are plausible such as, leader performance. This study explored the objective incongruence, yet subjective congruence can be more conclusive about the results of the present study.

LMX incongruence is more detrimental to members in high interaction situations. When the member perceives lower quality LMX than the leader, expectations regarding resource exchanges and behaviors are more likely to be unfulfilled for the member. Feedback seeking behavior being a member related outcome is likely to be affected more negatively in such conditions of incongruence. Second, it is likely that when there is a high degree of incongruence among the dyads, LMX congruence may become more critical to the members which in turn may give them a sense of belongingness within the dyad. Third, the relationship between leader–member dyads is affected by the social interactions facilitating the members' opinion sharing.

The study suggests that to fully grasp the implications of LMX theory, we need to consider the viewpoints of both the dyadic members at the same time.

The purpose of this paper is to know that how group resources (internal and external) and the relationship quality among group members relate to group performance.

Given the normative nature of group performance, the study is carried out in a contrived environment. Participants were 204 master of business administration students who were allocated to 51 study groups. Data were collected in three waves and from two different sources, i.e., students and instructors. Data analysis was carried out by employing regression analysis and the bootstrapping procedure, i.e., PROCESS.

The results of this paper reveal that an individual-level internal resource, i.e. time, positively predicts group performance, while group-level internal resources, i.e., group composition and group members’ experience, negatively predict group performance. Both external resources (external communication and instructor’s support) are found to have a positive effect on group performance. The relationship quality among group members partially relates to group performance. Instructor’s support as an external resource is found to moderate the relationship between only two aspects of relationship quality and group performance.

This study provides guidance to group members as to how they can utilize internal and external group resources and their relationship quality for enhancing their group performance. Managers in varied organizations can also utilize the findings of this study.

This study is unique in that it offers a new insight into internal and external resources and relationship quality, that is, from the perspective of group performance. The group resources included in the study are rarely found in the existing literature.

The purpose of this paper is to present a new cubic B-spline (CBS) approximation technique for the numerical treatment of coupled viscous Burgers’ equations arising in the study of fluid dynamics, continuous stochastic processes, acoustic transmissions and aerofoil flow theory.

The system of partial differential equations is discretized in time direction using the finite difference formulation, and the new CBS approximations have been used to interpolate the solution curves in the spatial direction. The theoretical estimation of stability and uniform convergence of the proposed numerical algorithm has been derived rigorously.

A different scheme based on the new approximation in CBS functions is proposed which is quite different from the existing methods developed (Mittal and Jiwari, 2012; Mittal and Arora, 2011; Mittal and Tripathi, 2014; Raslan et al., 2017; Shallal et al., 2019). Some numerical examples are presented to validate the performance and accuracy of the proposed technique. The simulation results have guaranteed the superior performance of the presented algorithm over the existing numerical techniques on approximate solutions of coupled viscous Burgers’ equations.

The current approach based on new CBS approximations is novel for the numerical study of coupled Burgers’ equations, and as far as we are aware, it has never been used for this purpose before.
