Purpose The purpose of this paper is to enhance the line congestion and to minimize power loss. Transmission line congestion is considered the most acute trouble during the operation of the power system. Therefore, congestion management acts as an effective tool in using the available power without breaking the system hindrances or limitations. Design/methodology/approach Over the past few years, determining the optimal location and size of the devices have pinched a great deal of consideration. Numerous approaches have been established to mitigate the congestion rate, and this paper aims to enhance the line congestion and minimize power loss by determining the compensation rate and optimal location of a thyristor-switched capacitor (TCSC) using adaptive moth swarm optimization (AMSO) algorithm. Findings An AMSO algorithm uses the performances of moth flame and the chaotic local search-based shrinking scheme of the bacterial foraging optimization algorithm. The proposed AMSO approach is executed and discussed for the IEEE-30 bus system for determining the optimal location of single TCSC and dual TCSC. Originality/value In addition to this, the proposed algorithm is compared with various other existing approaches, and the results thus obtained provide better performances than other techniques.

Abstract Transmission line congestion is considered the most acute trouble during the operation of the power system. Therefore, congestion management acts as an effective tool in utilizing the available power without breaking the system hindrances or limitations. Over the past few years, determining an optimal location and size of the devices have pinched a great deal of consideration. Numerous approaches have been established to mitigate the congestion rate and this paper aims to enhance the line congestion and minimize power loss by determining the compensation rate and optimal location of thyristor-controlled series capacitor (TCSC) using adaptive moth swarm optimization (AMSO) algorithm. An adaptive moth swarm AMSO algorithm utilizes the performances of moth flame and chaotic local search-based shrinking scheme of the bacterial foraging optimization algorithm. The proposed AMSO approach is executed and discussed for IEEE-30 bus system for determining the optimal location of single TCSC and dual TCSC. In addition to this, the proposed algorithm is compared with various other existing approaches and the results thus obtained provide better performances when compared with other techniques.

PurposeThe purpose of this paper is to examine the transformations of prosthetic practices in China, as well as the daily experiences and dilemmas arising from the everchanging practices since 1949. On the basis of materials, this paper explores an everyday perspective to review the history of technology.Design/methodology/approachEthnography was collected with the application of participant observations, informal interviews and in-depth interviews during a 13-months study at a rehabilitation center in Chengdu, China. The literature on prosthetic manufacturing was also reviewed for this paper.FindingsChina's prosthetic technology seems to evolve from traditional to modern. However, this progressive narrative – innovation-based timeline (Edgerton, 2006, xi) – has been challenged by daily practices. Due to institutional pressures, prosthetists are in a dilemma of selectively using their knowledge to create one kind of device for all prosthesis users with a certain kind of disability, thereby regulating the physical and social experiences of prosthesis users. Besides, prosthesis users are accustomed to prostheses made with old techniques, and must correct themselves from old experiences to the daily practices recognized by the selected techniques.Originality/valueThis paper provides a cross-cultural case to reexamine Edgerton's criticism of the progressive and orderly innovation-centric technological narrative. More importantly, it reviews the history and practices of China's prosthetics from daily experiences rather than Edgerton's concentration on technology; therefore, it provides an everyday perspective for future research on technological transformations.

Eagle Strategy

The power loss in electrical power systems is an important issue. Many techniques are used to reduce active power losses in a power system where the controlling of reactive power is one of the methods for decreasing the losses in any power system. In this paper, an improved particle swarm optimization algorithm using eagle strategy (ESPSO) is proposed for solving reactive power optimization problem to minimize the power losses. All simulations and numerical analysis have been performed on IEEE 30-bus power system, IEEE 118-bus power system, and a real power distribution subsystem. Moreover, the proposed method is tested on some benchmark functions. Results obtained in this study are compared with commonly used algorithms: particle swarm optimization (PSO) algorithm, genetic algorithm (GA), artificial bee colony (ABC) algorithm, firefly algorithm (FA), differential evolution (DE), and hybrid genetic algorithm with particle swarm optimization (hGAPSO). Results obtained in all simulations and analysis show that the proposed method is superior and more effective compared to the other methods.

Purpose The current review sought to bring light to the issue of an underexplored career phenomenon – career indecision. Career indecision is a significant developmental stage in one’s career life and has been a prominent topic in vocational psychology research in the past decades. However, it has received scant scholarly attention in the human resource development (HRD) field. Besides, the career indecision literature, in general, is lacking theoretical refinement and analytical review. The present study aims to stimulate HRD scholars’ interests by providing an introductory context for understanding the richness and potentialities of researching career indecision in the HRD area. Design/methodology/approach To address the gap, the author conducted an integrative review (Torraco, 2005, 2016) of 60 peer-reviewed articles and synthesized the existing knowledge of career indecision. More importantly, antecedent and outcome factors associated with career indecision were identified and analyzed. Findings A nomological network about career indecision was provided. Besides, the results of the integrative review revealed several omissions in the career indecision literature. Building upon that, implications for HRD research and practice are presented and discussed. Originality/value As an initial attempt to synthesize career indecision literature, this study sought to stimulate HRD professionals’ interest in examining this underexplored career phenomenon.

Purpose Corporate foreign bribery can have devastating consequences on communities and states. Over the past decade, there have been several promising developments, both national and international, that might increase the chances of victim states to receive remediation for the harm they suffered from foreign bribery. In particular, awareness has risen that victim states must be considered and new innovative items have been added to the toolbox of prosecutors in the fight against corruption that is assumed to also improve victim states’ standing in these procedures. This study aims to assess whether indeed victim states receive compensation through these novel procedures. Design/methodology/approach This study uses the three case studies of Switzerland, France and England and Wales for a comprehensive empirical and normative analysis of settlement agreements between defendants and prosecution authorities and of court jurisprudence. Findings This study shows that although de jure, it seems warranted to order the payment of remedies to victim states within domestic criminal proceedings, in practice, this rarely happens. A number of legal and practical obstacles account for this situation. This study, therefore, calls for the formulation of international guidelines containing the obligation to inform victim states of ongoing criminal proceedings on corporate foreign bribery, and guidance on how to identify the victim of this crime, as well as the damage caused. Originality/value This is the first contribution to verify whether claims that settlement agreements, recently introduced in England and Wales and France (and similar procedures are available in Switzerland), are beneficial for victim states in their quest to receive compensation. As this study shows that this is – not yet – the case in practice, this study proposes solutions that could lead the way for remediation of the harm caused by corporate corruption – and thereby, ultimately, to a more just outcome.
