Abstract

Purpose

Purpose of this paper are Real power loss reduction, voltage stability enhancement and minimization of Voltage deviation.

Design/methodology/approach

In HLG approach as per Henry gas law sum of gas dissolved in the liquid is directly proportional to the partial pressure on above the liquid. Gas dissolving in the liquid which based on Henry gas law is main concept to formulate the proposed algorithm. Populations are divided into groups and all the groups possess the similar Henry constant value. Exploration and exploitation has been balanced effectively. Ranking and position of the worst agents is done in order to avoid the local optima. Then in this work Mobula alfredi optimization (MAO) algorithm is projected to solve optimal reactive power problem. Foraging actions of Mobula alfredi has been imitated to design the algorithm. String foraging, twister foraging and backward roll foraging are mathematically formulated to solve the problem. In the entire exploration space the Mobula alfredi has been forced to discover new regions by assigning capricious position. Through this approach, exploration competence of the algorithm has been improved. In all iterations, the position of the Mobula alfredi has been updated and replaced with the most excellent solution found so far. Exploration and exploitation capabilities have been maintained sequentially. Then in this work balanced condition algorithm (BCA) is projected to solve optimal reactive power problem. Proposed BCA approach based on the conception in physics- on the subject of the mass; incoming, exit and producing in the control volume. Preliminary population has been created based on the dimensions and number of particles and it initialized capriciously in the exploration space with minimum and maximum concentration. Production control parameter and Production probability utilized to control the exploration and exploitation.

Findings

Proposed Henry's Law based -soluble gas optimization (HLG) algorithm, Mobula alfredi optimization (MAO) algorithm and BCA are evaluated in IEEE 30 bus system with L-index (Voltage stability) and also tested in standard IEEE 14, 30, 57, 118, 300 bus test systems without L- index. Real power loss minimization, voltage deviation minimization, and voltage stability index enhancement has been attained.

Originality/value

For the first time Henry's Law based -soluble gas optimization (HLG) algorithm, Mobula alfredi optimization (MAO) algorithm and BCA is projected to solve the power loss reduction problem.

Abstract

Purpose

The purpose of this study is for examining the evolution of stakeholder influence and the trans-period effect (TPE) of process performance of public–private partnerships (PPPs). TPE refers to the ripple effect of project performance across different phases of a PPP.

Design/methodology/approach

Social network analysis is used to analyze each stakeholder’s influence on PPP performance. For examining the TPE, partial least squares structural equation modelling is conducted.

Findings

The performance in the five phases (e.g. initiation and planning, procurement, construction, operation and transition) of PPPs exhibits significant TPE. The stakeholder network varies in different phases. The most influential stakeholder is a public authority, followed by a public initiator and a private consortium.

Research limitations/implications

The project type of PPPs is not considered in the stakeholder network analysis. Future work should focus on developing a multidimensional stakeholder network by considering the typology of the project. Moreover, the TPE cannot reflect the relationships between the KPIs in the different phases, and thus, further study is required.

Practical implications

This research provides a useful tool for measuring the life cycle outputs and outcomes of PPPs through enhanced process-oriented performance measurement. The developed PMS enable practitioners to have a better understanding of the process performance of the projects and then ensure informed decision-making about actions to be required and taken to improve future performance.

Originality/value

This study contributes to knowledge of performance management by simultaneously addressing the process and stakeholder management theories within the context of PPPs. The proposed PMS provides an insight into managing stakeholders’ influences to enhance the life cycle performance of PPPs.

Abstract

Self‐efficacy has been described as a malleable quality based on individual perceptions of ability in given situations and has repetitively been linked to performance gains and other positive organizational outcomes. Less research has addressed the processes that shape individual efficacy levels. This article explores the role of emotional intelligence and causal reasoning patterns in the development of self‐efficacy beliefs. A research model is forwarded along with associated propositions. Lastly, the implications, limitations, and future research directions of this research are discussed.

Abstract

BOOKS and Libraries for the Blind form the subject of a paper by Dr. Robert C. Moon in the May Library Journal. The writer is the son of William Moon, the inventor of the system of embossed writing bearing his name. He describes the systems of writing for the blind in use, and the various agencies for circulating literature. After examining the existing departments for the blind in Public Libraries, he comes to the conclusion that “all the libraries need more books, and if they are to reach and teach the adult blind they must have a fair proportion of them in the Moon type. All Public Libraries should possess a few works printed in the various types, care being taken to have a good supply of those embossed in the special type which is taught in the schools for the blind of the immediate locality, in order that the pupils in vacation time, and the graduates of the schools may be provided with reading matter, but the infirm and aged blind will be found in almost all communities, and for them books printed in the Moon type are indispensable. Alice S. Tyler describes the League of Library Commissions. “The success of the experiment in co‐operation which was inaugurated in 1901 by the library commissions of Wisconsin, Minnesota, and Iowa, whereby printed matter of common interest and equal necessity and value to these commissions was issued jointly, led to the suggestion that a national organization might more economically carry forward these and other lines of co‐operative work, leaving to the overcrowded state commission workers more time and money for the peculiar problems of each state.” This suggestion was brought up at the St. Louis conference, and resulted in an organization being formed under the title of the League of Library Commissions, consisting of one representative from each of the commissions included. The particular directions in which the League will promote co‐operative work are: carefully prepared lists of books for first purchase for small libraries; lists of new books which, upon examination, had been found desirable ; handbook of suggestions and direction as to the organization and management of small libraries; printed statement regarding the aims and methods of state library commissions, with comparison of their laws; definite help and suggestions on the subject of library buildings, especially floor‐plans arranged for economic administration, growing out of the experience of the library commissions in connection with the erection of Carnegie and other library buildings within the last few years; united effort to bring to the attention of book publishers the urgent need of good, durable binding, adequate indexing, &c.

Abstract

Purpose

This paper investigates the policy changes made towards infrastructure public–private partnerships (PPPs). The purpose of this study is to empirically identify the policy risks associated with the development of PPPs and to assess their impacts on the projects.

Design/methodology/approach

A case study of the policy changes that have been implemented for PPPs in China over the past seven years has been undertaken and is presented in this study. The causal loop diagrams are applied to assess and illustrate the potential impacts of the risks as a result of such changes on PPPs.

Findings

A sequence of the policy risks, which relate to PPP risk allocation, contract management and implementation, payment and abatement mechanisms and financing, has been identified. It is also found that the identified risks will generate significant but negative impacts on PPPs, leading to an ineffective project delivery, low revenue, poor service quality and even contract breach.

Practical implications

This research provides the private-sector entities that will embark on PPPs with an insight into managing and controlling policy risks over the project's lifecycle.

Originality/value

PPPs have been critical for infrastructure development worldwide. Nevertheless, they have been a controversy, as many of them were subjected to poor outputs. Consequently, a variety of political mechanisms has been implemented to enhance the governance for PPPs. Policy can bring not only benefits but also risks and, however, policy risks of PPPs with a particular assessment for their potential impacts have received limited attention. Therefore, the study presented in this paper will contribute to the identification and assessment of policy risks within the context of PPPs.

Abstract

Purpose

Both customer engagement (CE) and corporate social responsibility (CSR) have been linked to customer loyalty. Past studies use service dominant logic and customer value co-creation to explain this relationship. The purpose of this paper is to apply utility theory to develop and test a new theoretical model based on CSR initiative preference to understand the relationship between CE and customer loyalty to the organisation in a CSR platform.

Design/methodology/approach

This empirical study uses choice theory in the form of best-worst scaling, and structural equation modelling, to measure the impact of sports club members’ choice preferences for a range of CSR initiatives on their intention to engage with the initiative and subsequent loyalty to the club.

Findings

This study highlights the importance of engaging members in the CSR strategy they prefer as it enhances not only the extra value to the organisation via customer loyalty to the organisation, but also CE with the organisation. Furthermore, the study reveals age and gender impact on the relationship between CE in CSR initiatives and customer loyalty.

Originality/value

This study extends CE to CSR behaviours and provides empirical evidence for a unique theoretical framework of CE based on utility theory. It also highlights the need to take into account moderating variables such as customer demographics.

Abstract

Purpose

The purpose of the paper is to determine the effects of a hypocaloric diet with a low-glycaemic index (GI) on weight loss and postprandial blood glucose and assess both the satiety and palatability of the diet.

Design/methodology/approach

A clinical trial was conducted with ten women (mean age: 38.8±11.3 years; body mass index: 27.2±3.5 kg/m2) submitted to a hypocaloric diet, assessments were performed at baseline and after seven days of treatment.

Findings

Significant reductions were found in body weight (1.1±0.7 kg; p=0.001), triccipital skinfold (2.87±3.24 mm; p=0.021) and waist circumference (3.6±4.8 cm; p=0.041). Mean fasting and postprandial blood glucose values were 88.7±6.1 mg/dL and 91.6±9.6 mg/dL, respectively. Responses regarding satiety and palatability of the low-GI diet were predominantly “extremely satisfied” and “I liked it very much,” respectively, for all meals and throughout all seven days of the study.

Originality/value

The present study demonstrated the benefits of a low-GI diet with regard to weight loss, blood glucose control and satiety. The diet proved to be palatable, which could favor compliance with long-term treatment.
