Abstract

Purpose

As a result of the deregulations in the power system networks, diverse beneficial operations have been competing to optimize their operational costs and improve the consistency of their electrical infrastructure. Having certain and comprehensive state assessment of the electrical equipment helps the assortment of the suitable maintenance plan. Hence, the insulation condition monitoring and diagnostic techniques for the reliable and economic transformers are necessary to accomplish a comprehensive and proficient transformer condition assessment.

Design/methodology/approach

The main intent of this paper is to develop a new prediction model for the aging assessment of power transformer insulation oil. The data pertaining to power transformer insulation oil have been already collected using 20 working power transformers of 16-20 MVA operated at various substations in Punjab, India. It includes various parameters associated with the transformer such as breakdown voltage, moisture, resistivity, tan δ, interfacial tension and flashpoint. These data are given as input for predicting the age of the insulation oil. The proposed aging assessment model deploys a hybrid classifier model by merging the neural network (NN) and deep belief network (DBN). As the main contribution of this paper, the training algorithm of both NN and DBN is replaced by the modified lion algorithm (LA) named as a randomly modified lion algorithm (RM-LA) to reduce the error difference between the predicted and actual outcomes. Finally, the comparative analysis of different prediction models with respect to error measures proves the efficiency of the proposed model.

Findings

For the Transformer 2, root mean square error (RMSE) of the developed RM-LA-NN + DBN was 83.2, 92.5, 40.4, 57.4, 93.9 and 72 per cent improved than NN + DBN, PSO, FF, CSA, PS-CSA and LA-NN + DBN, respectively. Moreover, the RMSE of the suggested RM-LA-NN + DBN was 97.4 per cent superior to DBN + NN, 96.9 per cent superior to PSO, 81.4 per cent superior to FF, 93.2 per cent superior to CSA, 49.6 per cent superior to PS-CSA and 36.6 per cent superior to LA-based NN + DBN, respectively, for the Transformer 13.

Originality/value

This paper presents a new model for the aging assessment of transformer insulation oil using RM-LA-based DBN + NN. This is the first work uses RM-LA-based optimization for aging assessment in power transformation insulation oil.

Abstract

In this paper we analyze the influence of transaction costs on the stock market reaction to global alliance formation. In particular, we analyze to what extent the stock market reacts negatively to the presence of attributes that increase motivation or coordination costs. We adopt a relational framework, analyzing the direct impact of these attributes not only on transaction costs but also on the potential synergies of the alliance and the incentives to invest in the relationship. Our results show that the stock market reacts negatively to transaction costs only in connection with free riding hazards.

Abstract

Firms operate in a market for their corporate assets, wherein important assets being bought and sold are business units. This market is therefore a primary mechanism for firm reconfiguration, and offers the opportunity for firms to gain performance advantage as they prepare for and engage in their boundary-changing moves. This paper focuses on resource reconfiguration between firms, and examines internally and externally driven sources of performance heterogeneity in firms’ use of the market for firm reconfiguration. Viewing between-firm resource reconfiguration through three theoretical lenses surfaces several potential avenues for firm differentiation. For one, the necessity of firms’ possessing capabilities to execute both sides of the external resource reconfiguration transaction – acquisition and divestiture capabilities – is revealed. For another, the institutional prerequisites that are needed in the operating environment for a firm to build a sustainable resource reconfiguration strategy are brought to the fore, and are well illustrated by the private equity industry. Lastly, the potential benefits of using the transactional view of firm scope to animate the study of external resource reconfiguration are raised. Taken together, these elements lead to a research agenda around resource reconfiguration across firm boundaries.

Abstract

Although primarily treated as two distinct research streams, strategic alliances and mergers and acquisitions together occupy much of the strategic management discourse. Alliances, in many cases, end in acquisitions as firms use alliances as intermediate strategic options to eventually acquire a partner. As the discipline of strategy matures and the frequency and the volume of inter-firm cooperation continue to rise, it is imperative to integrate these two research streams for a holistic understanding of the theory of the firm. The purpose of this conceptual piece is threefold. First, we review the extant studies that combine these two governance modes: alliance and acquisitions. Second, drawing on the dominant strategic management theories, we highlight how prior inter-firm alliances inform future acquisitions in terms of (a) pre-combination decisions, (b) post-deal integration processes, (c) alternatives and strategies, and (d) performance outcomes. Finally, in view of the emerging trends and evocative gaps, we offer a conceptual road map to encourage future theoretical development and empirical research.

Abstract

Hemisphericity in behaviour studies is the role and dominance of right bran/left brain in the human brain, each side of which has varying roles and characteristics, thereby leading to different thinking orientations in the human. A study was conducted to measure the hemisphericity orientation of construction and design engineers in a large public construction organization. We know from literature that people of different hemisphericity orientations have unlike personalities and dissimilar perspectives of specific situations. The essential characteristics of hemisphericity as established in literature are presented and used in analysing the organization. From this study of engineers, it was seen that construction engineers in the organization, State Department of Engineering Construction (SDEC), are predominantly left‐brained while design engineers are predominantly right‐brained. This difference in orientation partially explains why the design and construction engineers at SDEC are unable to see eye‐to‐eye in issues concerning implementation of drawings. Left hemisphere dominant engineers are also seen to desire more organizational changes than their right hemisphere dominant counterparts. Ideally, researchers believe that a 50–50 distribution of hemisphericities in large organizations is desirable. Details, analysis, and recommendations are presented in the paper.

Abstract

The benefits of network relations for firms’ competitive advantage are increasingly acknowledged in the strategic management literature. Yet, the cost implications of engaging in network-specific relations, stemming from the irreversibility of sunk costs invested in creating network relations, are largely ignored. Such costs tend to be especially pronounced in high technology firms. It follows that the costs of creating network relations may mask the benefits of such relations, suggesting that networks can be a competitive risk for firms in cases where network relations unexpectedly terminate. This chapter adopts a cost-benefit approach to an empirical analysis showing that while in the long term, network relations enhance high technology firms’ performance, short-term efforts in creating network relations may hamper their performance. Furthermore, we show that greater technological intensity intensifies the negative performance implications of short term network participation and the positive performance implications of long term network participation.

Abstract

The study here responds to the view that the crucial problem in strategic management (research) is firm heterogeneity – why firms adopt different strategies and structures, why heterogeneity persists, and why competitors perform differently. The present study applies complexity theory tenets and a “neo-configurational perspective” of Misangyi et al. (2016) in proposing complex antecedent conditions affecting complex outcome conditions. Rather than examining variable directional relationships using null hypotheses statistical tests, the study examines case-based conditions using somewhat precise outcome tests (SPOT). The complex outcome conditions include firms with high financial performances in declining markets and firms with low financial performances in growing markets – the study focuses on seemingly paradoxical outcomes. The study here examines firm strategies and outcomes for separate samples of cross-sectional data of manufacturing firms with headquarters in one of two nations: Finland (n = 820) and Hungary (n = 300). The study includes examining the predictive validities of the models. The study contributes conceptual advances of complex firm orientation configurations and complex firm performance capabilities configurations as mediating conditions between firmographics, firm resources, and the two final complex outcome conditions (high performance in declining markets and low performance in growing markets). The study contributes by showing how fuzzy-logic computing with words (Zadeh, 1966) advances strategic management research toward achieving requisite variety to overcome the theory-analytic mismatch pervasive currently in the discipline (Fiss, 2007, 2011) – thus, this study is a useful step toward solving the crucial problem of how to explain firm heterogeneity.

Abstract

Purpose

The purpose of this study is to analyse the mediating and moderating effects of relational flexibility norms on relationship building capacities and export performance.

Design/methodology/approach

The study followed a quantitative and cross-sectional approach. The analysis was applied to 95 Peruvian Exporting SMEs which were examined through structural equation modelling (SEM) using AMOS 24.0 statistical package. The responses were gathered through telephone and personal interviews which were tested using the Mann–Whitney U test, finding no statistically significant differences.

Findings

The main finding of the study is to demonstrate the indirect effect of relational flexibility norms on the export performance of SMEs through relationship-building capabilities. In this way, these capabilities become very important variables in the export management of SMEs, since they directly affect the relationship of the Exporter–Importer dyad.

Research limitations/implications

One of the limitations is the cross-sectional type study that applies to the short-term effects of relational norms. Organizational characteristics and other factors that may affect export performance should also be considered in future research, as well as longitudinal studies should be developed.

Practical implications

The study allows SMEs to focus management efforts on strengthening the relationship – building capabilities, which are very important given SMEs' resource constraints. Therefore, an adequate management of relations with importers can contribute to the reduction of control and coordination costs; and have a positive impact on export performance. Similarly, the study contributes to the management of export promotion by suggesting that one area to be prioritized is the strengthening of the relationship capacities of exporting SMEs.

Originality/value

The study provides the analysis of the mediating effect of the relationship-building capability between relational flexibility and export performance. In this way, it enriches the theoretical analysis and contributes with the empirical evidence of an emerging country like the case of Peru.

Abstract

While there is an increasing understanding of the challenges that can emerge in integration processes of cross-border mergers and acquisitions, there is a scarcity of research on how the different integrative activities should be temporally sequenced. Based on an in-depth analysis of three acquisitions, we find that structural and cultural integration are intertwined. We find that cultural integration will begin only once structural integration is in progress. Cultural differences can, however, impede structural integration if structural integration is done in conflict with the existing culture of the acquired company. Thus, structural integration should come first, but it should be done in appreciation with the acquired company’s existing culture. Cultural change is then facilitated in an iterative manner over time by the new structure. Our chapter contributes to an improved understanding of the temporal dynamics of integration by demonstrating the mutually reinforcing effects of structural and cultural integration in cross-border acquisitions.
