The Relationship

This study explores the relationship between team cohesion and team learning by adopting a nonlinear approach. A quantitative study with a sample composed of 82 organizational teams was conducted. Radial basis function (RBF) interpolation models were used, and results showed that the best predicting ability was obtained by the Thin Plate RBF model, which revealed that an increase in both dimensions of cohesion leads to an increase in team learning up to a certain threshold. Moreover, our results showed that the maximum value of team learning is obtained at higher values of task cohesion and moderate values of social cohesion.

Team cohesion is an important antecedent of team performance, but our understanding of this relationship is mired by inconsistencies in how cohesion has been conceptualized and measured. The nature of teams is also changing, and the effect of this change is unclear. By meta-analyzing the cohesion-performance relationship ( k = 195, n = 12,023), examining measurement moderators, and distinguishing modern and traditional team characteristics, we uncovered various insights. First, the cohesion-performance relationship varies based on degree of proximity. More proximal measures –task cohesion, referent-shift, and behaviorally-focused– show stronger relationships compared to social cohesion, direct consensus, and attitudinally-focused, which are more distal. Differences are more pronounced when performance metrics are also distal. Second, group pride is more predictive than expected. Third, the cohesion-performance relationship and predictive capacity of different measures are changing in modern contexts, but findings pertaining to optimal measurement approaches largely generalized. Lastly, important nuances across modern characteristics warrant attention in research and practice. Plain Language Summary Team cohesion is an important antecedent of team performance, but our understanding of this relationship is mired by inconsistencies in how cohesion has been conceptualized and measured. The nature of teams has also changed over time, and the effect of this change is unclear. By meta-analyzing the cohesion-performance relationship ( k = 195, n = 12,023), examining measurement moderators, and distinguishing between modern and traditional team characteristics, we uncovered various insights for both research and practice. First, the cohesion-performance relationship varies based on degree of proximity. Measures that are more proximal to what a team does – those assessing task cohesion, utilizing referent shift items, and capturing behavioral manifestations of cohesion – show stronger relationships with performance compared to those assessing social cohesion, utilizing direct consensus items, and capturing attitudinal manifestations of cohesion, which are more distal. These differences are more pronounced when performance metrics are also more distal. Second, despite being understudied, the group pride-performance relationship was stronger than expected. Third, modern team characteristics are changing both the overall cohesion-performance relationship and the predictive capacity of different measurement approaches, but findings pertaining to the most optimal measurement approaches largely generalized in that these approaches were less susceptible to the influence of modern characteristics. However, in some contexts, distal cohesion metrics are just as predictive as their more proximal counterparts. Lastly, there are important nuances across different characteristics of modern teams that warrant additional research attention and should be considered in practice. Overall, findings greatly advance science and practice pertaining to the team cohesion-performance relationship.

The Relationship

The price of land is an important matter that needs to be assessed by stakeholders. The study of land prices has an important role in seeing the stability of the property market. Several factors affect the property business such as accessibility, public facilities and social facilities. Utan Kayu Selatan is the largest village in Matraman Sub-District with an area of ​​1,12 kilometers. The potential of the property business is very tempting for investors to property developers. One of the economic sector developments is Utan Kayu Raya Road, which can increase land prices in the surrounding area. The factors that influence land prices can be analyzed through several approaches such as regression, mass appraisal and other. In this study, the method used in estimating land prices is the Radial Basis Function (RBF), by looking at the relationship between the distance of plot to roads, public facilities and social facilities. Modeling is carried out based on samples determined on ZNT and NJOP land prices. Furthermore, the calculation of the distance is done by using network analysis. As a result, the RMSE value for the NJOP RBF model and the ZNT RBF model is IDR 1.179.839 and IDR 2.972.345. Meanwhile, the CoV values ​​for both models were 6.2% and 6%. In the comparison of ZNT price predictions with market prices, the highest difference is IDR 13.119.915 and the lowest difference is IDR 537.009. While on the NJOP price prediction, the highest difference is IDR 15.797.583 and the lowest difference is IDR 291.270.

Abstract This cross-sectional study aimed to examine the association between sporting experiences and the perception of team cohesion according to sex among youth Brazilian recreational athletes. Participants were 253 youth athletes with age average of 12.97 ± 0.98 years.  Athletes represented the following sports: Indoor soccer (n=20); basketball (n=62); handball (n=123) and; volleyball (n=48). The instruments used were the Youth Experience Survey for Sport (P-YES-S) and the Youth Sport Environment Questionnaire (P-YSEQ). Independent sample t-test revealed significant difference between sexes in the dimensions of Personal Skills (p=0.02) and Task Cohesion (p=0.02). The following significant correlations were found for girls: Task Cohesion with Personal Skills (r=0.48), Initiative Experiences (r=0.37); and Social Cohesion with Personal Skills (r=0.41), Cognitive Skills (r=0.43) and Initiative Experiences (r=0.32). For boys, it was found the following correlations: Task Cohesion with Personal Skills (r=0.19), Initiative Experiences (r=0.42) and Negative Experiences (r=-0.22); and Social cohesion with Personal Skills (r=0.18) and Initiative Experiences (r=0.30). Multiple regression analysis indicated that sports experiences are significant predictors of task (R2=0.21; F=17.838; p<0.01) and social cohesion (R2=0.10; F=7.440; p<0.01). It can be concluded that positive sporting experiences may predict social and task cohesion among youth athletes.

The Relationship

The general purpose of the present study was to determine if perceptions of team cohesion are related to the interpretation athletes attach to their precompetition anxiety. Specifically examined was the association between athlete perceptions of task cohesiveness (Individual Attractions to the Group– Task, ATG-T, and Group Integration–Task, GI-T) and the degree to which perceptions of the intensity of precompetition anxiety symptoms (cognitive and somatic) were viewed as facilitative versus debilitative. Participants were athletes (N = 392) from the sports of soccer, rugby, and field hockey. Each athlete completed the Group Environment Questionnaire (Carron, Widmeyer, & Brawley, 1985) after a practice session. A directionally modified version of the Competitive State Anxiety Inventory-2 (Martens, Burton, Vealey, Bump, & Smith, 1990) was completed just prior to a competition. Results showed that athletes who perceived their cognitive anxiety as facilitative had higher perceptions of both ATG-T and GI-T, χ2 (2, N = 260) = 8.96, p < .05, than athletes who perceived their cognitive anxiety as debilitative. Also, athletes who perceived their somatic anxiety as facilitative had higher perceptions of GI-T, χ2 (2, N = 249) = 5.85, p < .05.

Purpose Based on the interpersonal interaction perspective of team cohesion, this study aims to examine the effects of team boundedness, formal coordination and organization tenure diversity on both task and social cohesion. The authors test for the interaction effect of organization tenure diversity on the relationships between the independent variables and the dimensions of team cohesion. Design/methodology/approach Data was collected from 111 software development teams and aggregated to the team level. Common latent factor test for common method bias showed no significant bias. Structural equation modelling (SEM) was used to test all the hypotheses. Findings SEM results show that team boundedness and formal coordination have positive and significant association with both dimensions of team cohesion. Formal coordination was found to be a stronger positive predictor for task cohesion than for social cohesion. Organization tenure diversity was found to be a stronger negative predictor for social cohesion than for task cohesion. Organization tenure diversity in the team moderates the relationship between formal coordination and task cohesion. Research limitations/implications The data was collected using a cross-sectional design. However, the authors have mitigated the effect of common method variance by adopting both procedural and statistical methods. Originality/value This paper expands extant literature by examining the antecedents of two important components of team cohesion, task and social cohesion. The authors proposed and found that the independent variables have different impacts on task and social cohesion. This study furthers both theory and practice by considering team boundedness as a variable of interest and its impact on internal team dynamics.

This paper proposes an algorithm to compute the sensitivity of the Radial-Basis Function Neural Network (RBFNN) due to the errors of the inputs and others parameters of the net works. For simplicity and practicality, all inputs and weights are assumed to be independent and identically distributed (i.i.d) with uniform distribution. A number of simulations are conducted and the good agreement between the experimental results and the theoretical results verifies the reliability and feasibility of the proposed algorithm. The relationship between the sensitivity of RBFNN and input error and the perturbation of others parameters is given.

Purpose The purpose of this study is to investigate the effects of team boundedness, and formal coordination on task and social cohesion and the moderating effect of organization tenure diversity. Design/methodology/approach Data was gathered from the responses of 398 team members and leaders working in 111 software development teams to a questionnaire survey. The hypotheses were all tested using structural equation modelling. Findings The results show team boundedness and formal coordination have positive and significant associations with task and social cohesion. Formal coordination is a stronger positive predictor for task than social cohesion. Organization tenure has a greater negative effect on social cohesion than task cohesion and moderates the relationship between formal coordination and task cohesion. Practical implications Therefore, for organizations to optimize team cohesion the impact of antecedent variables on social and task cohesion should be taken into considering in planning strategies for improvement. Originality/value This paper has an original approach by adding to the literature through an examination of the antecedent variables of task and social cohesion which are two key components of team cohesion.
