Abstract

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.

Abstract

Purpose

The purpose of this paper is an examination of the literature on team boundary activity to trace how team boundary activity has evolved as a construct and examine the dimensions of team boundary activity and their relationships. It highlights the need for a deeper examination of the dimensions of buffering and reinforcement, and why buffering and reinforcement are required. It presents the case of why it is important to study this topic and maps out areas for future research.

Design/methodology/approach

The paper reviews conceptual and empirical papers published on team boundary activity in reputed journals between the years 1984 and 2016.

Findings

The focus of research in team boundary activity has been on external interactions of the team (boundary spanning), and very few papers have studied the activities through which the team defines and defends its borders (boundary strengthening). These boundary-strengthening activities can be equally important for innovation and learning in externally dependent teams. Further, there is a need to clearly distinguish these constructs from other variables like team identification. Another area that has here-to not been researched is the relationships between the dimensions of team boundary activity. Last, there is a need to consider a wider range of antecedents, outcomes and moderators of team boundary activity.

Research limitations/implications

This paper is based on past empirical and conceptual papers, identified using search terms such as team boundary activity, team boundary spanning and external communication. Other related areas can also be explored for identifying variables of interest.

Originality/value

As opposed to previous reviews which focused mainly on team boundary spanning, this paper considers all dimensions of team boundary activity, with special focus on buffering and reinforcement. It proposes a 2 × 2 framework to explain the effect of boundary-spanning and boundary-strengthening activities on the achievement of team objectives. It examines the cyclical nature of relationship between team boundary activity and team performance. It highlights measurement issues in the area of team boundary activity.

Abstract

Purpose

The purpose of this paper is to understand the critical factors associated with growing fertilizer usage culminating in contamination of soil/water in agriculturally intensive regions of Uttar Pradesh, India. The agriculture sector is seen as one of the major contributors in ensuring food security, however adoption of sustainable agriculture to protect water resources from contamination due to fertilizers and pesticides is becoming pressing to achieve long term environmental security.

Design/methodology/approach

A two staged study aimed at monitoring the soil quality status followed by stakeholder survey has been attempted. Attitude-behavior framework based on the theory of reasoned action has been tried to explain the fertilizer use behavior in the study. The results are analyzed through Analysis of variance.

Findings

Soil monitoring data showed nitrate and total nitrogen loadings beyond the permissible limit in the identified regions. A questionnaire aimed at determining farmer’s attitude toward fertilizer usage showed a significant influence of factors like net farm income, overall farm yield, extension services, farmer characteristics on one hand and risks associated with changing farming practices, costs of substitutes available, market-based instruments like subsidies and loans on the other. Divergent responses were observed with respect to farmer’s perceived risks from adopting to organic substitutes, linkages of fertilizer application with environmental degradation and the level of adoption of sustainable agricultural practices.

Research limitations/implications

The study can be scaled up to study the inter-regional differences by benchmarking regional responses. It would be interesting to extend the work to find solutions from the farmers as alternative fertility management strategies. The items used in questionnaire are self-made; hence there is still a possibility of enhancing the robustness of scale by applying advanced statistical techniques.

Practical implications

Results of the study indicate excessive nitrogen loadings in farm soils which is an indicator of potential future nitrate contaminated zones or vulnerable zones emerging in agricultural intensive regions. Findings reinforce the role of education, knowledge transfer and awareness for long-term agricultural sustainability. The paper highlights the urgency for reorientation of the support system by the government and policymakers.

Originality/value

The paper attempts to understand the linkage between the agricultural productivity and the environmental implications followed by the reasons culminating in the agri-environmental imbalance. On-site monitoring study followed by assessment of reasons culminating in this scenario has not been attempted earlier and this paper contributes to understanding at dual level. This paper emphasizes on the insights of stakeholder which is instrumental in ensuring agricultural sustainability or otherwise. It takes the position that the farmer’s farm management behavior is strongly influenced by factors like food security and income, keeping environmental quality at second place. It also identifies the barriers for organic farming and other alternative systems as well as explores the economic, social, and philosophical aspects of sustainable agriculture.

Abstract

Purpose

The purpose of this paper is to develop a methodology for knowledge discovery in emergency response service databases based on police occurrence reports, generating information to help law enforcement agencies plan actions to investigate and combat criminal activities.

Design/methodology/approach

The developed model employs a methodology for knowledge discovery involving text mining techniques and uses latent Dirichlet allocation (LDA) with collapsed Gibbs sampling to obtain topics related to crime.

Findings

The method used in this study enabled identification of the most common crimes that occurred in the period from 1 January to 31 December of 2016. An analysis of the identified topics reaffirmed that crimes do not occur in a linear manner in a given locality. In this study, 40 per cent of the crimes identified in integrated public safety area 5, or AISP 5 (the historic centre of the city of RJ), had no correlation with AISP 19 (Copacabana – RJ), and 33 per cent of the crimes in AISP 19 were not identified in AISP 5.

Research limitations/implications

The collected data represent the social dynamics of neighbourhoods in the central and southern zones of the city of Rio de Janeiro during the specific period from January 2013 to December 2016. This limitation implies that the results cannot be generalised to areas with different characteristics.

Practical implications

The developed methodology contributes in a complementary manner to the identification of criminal practices and their characteristics based on police occurrence reports stored in emergency response databases. The generated knowledge enables law enforcement experts to assess, reformulate and construct differentiated strategies for combating crimes in a given locality.

Social implications

The production of knowledge from the emergency service database contributes to the government integrating information with other databases, thus enabling the improvement of strategies to combat local crime. The proposed model contributes to research on big data, on the innovation aspect and on decision support, for it breaks with a paradigm of analysis of criminal information.

Originality/value

The originality of the study lies in the integration of text mining techniques and LDA to detect crimes in a given locality on the basis of the criminal occurrence reports stored in emergency response service databases.

Abstract

Purpose

The purpose of this paper is to develop a method for the discovery of knowledge in emergency response databases based on police incident reports, generating information that identifies local criminal demands that allow the selection of the appropriate policing strategies portfolio to solve the problem.

Design/methodology/approach

The developed model uses a methodology for the discovery of knowledge involving text mining techniques using Latent Dirichlet Allocation (LDA) integrated with the ELECTRE I multicriteria method.

Findings

The developed method allowed the identification of the most common criminal demands that occurred from January 1 to December 31, 2016, in the policing areas studied. One of the crimes does not occur homogeneously in a particular locality. In this study, it was initially observed that 40 per cent of the crimes identified in the Integrated Public Safety Area 5, or AISP-5, (historical city center of RJ) had no correlation with AISP-19 (Copacabana - RJ), and 33 per cent of crimes crimes in AISP-19 were not identified in AISP-5. This finding guided the second part of the method that sought to identify which portfolio of policing strategies would be most appropriate for the identified demands. In this sense, using the ELECTRE I method, eight different scenarios were constructed where it can be identified that for each specific criminal demand set there is a set of policing strategies to be applied.

Research limitations/implications

The collected data represent the social dynamics of neighbourhoods in the central and southern zones of the city of Rio de Janeiro during the specific period from January 2013 to December 2016. This limitation implies that the results cannot be generalised to areas with different characteristics.

Practical implications

The developed methodology contributes in a complementary way to the identification of criminal practices and their characteristics based on reports of police occurrences stored in emergency response databases. The knowledge generated through the identification of criminal demands allows law enforcement decision makers to evaluate and choose among the available policing strategies, which best suit the reality they study, and produce the reduction of criminal indices.

Social implications

It is possible to infer that by choosing appropriate strategies to combat local crime, the proposed model will increase the population’s sense of safety through an effective reduction in crime.

Originality/value

The originality of the study lies in the integration of text mining techniques, LDA and the ELECTRE I method for detecting crime in a given location based on crime reports stored in emergency response databases, enabling identification and choice, from customized policing strategies to particular criminal demands.

Abstract

Purpose

There are limited studies addressing how choosing a maintenance strategy can contribute towards maximising outputs from given inputs, thereby minimising costs and improving a company’s competitiveness. The analytic hierarchy constant sum method (AHCSM) is used to access the appropriateness of maintenance strategies for improving the overall efficiency of a structural steel fabrication construction company.

Design/methodology/approach

A semi-structured interview was formulated with the stakeholders of the quality department to understand the company’s maintenance portfolio and its current functional capability. The information from this case study was then dissected to represent the factors that the company deemed appropriate for evaluating their maintenance strategy. The AHCSM approach provided a framework, which ranked the importance of factors that are sensitive to the construction industry and rank the suitability of maintenance strategies.

Findings

Factors affecting the selection of maintenance strategies to improve business efficiency are productivity, quality, reliability, cost, safety and work environment, morale, inventory and flexibility. Total productive maintenance strategy produces the most desirable outcome; however, the predictive or condition-based maintenance strategy provides an optimum solution for the case study company while considering the equipment usage, frequency of production and the current economic climate.

Originality/value

The approach presented allows practitioners to consider ways to increase the level of production and improve the efficiency of construction businesses without a high increase in investment. The findings can inform gaps in existing maintenance approaches in achieving business objectives.

Abstract

Purpose

The aim of this paper is to assess the trend of changes of nutritional status and environmental quality of different decomposing organic wastes in different phases of vermicomposting utilizing an indigenous earthworm's species Perionyx excavatus.

Design/methodology/approach

Four different organic wastes were selected as basic ingredients for vermicompost production. Dried waste materials (2 kg) of each were mixed with dried cow dung and placed in experimental plastic trays with 60 individuals of selected earthworm species. Samples were collected from each tray at an interval of 15 days. Six trays were used: three were with both wastes, three trays having only wastes were treated as control.

Findings

Regression equation has shown the rate of change of nutrients – both in control and experiment vermicomposting units over time – which revealed significant changes of C, N, P and C/N ratio during different phases of vermicomposting.

Practical implications

Vermitechnology is now being considered as an eco‐friendly, user‐friendly and cost‐effective biotechnological tool for the conversion of decomposable organic wastes into valuable organic manure, ensuring pollution abatement, self employment and sustainability in agriculture.

Originality/value

The paper helps to identify the potential of locally available earthworm species and organic materials for the mass production of vermicompost involving local peoples and locally available bioresources.
