Abstract

Purpose

The purpose of this paper is to propose an algorithm that combines the particle swarm optimization (PSO) with the biogeography-based optimization (BBO) algorithm.

Design/methodology/approach

The BBO and the PSO algorithms are jointly used in to order to combine the advantages of both algorithms. The efficiency of the proposed algorithm is tested using some selected standard benchmark functions. The performance of the proposed algorithm is compared with that of the differential evolutionary (DE), genetic algorithm (GA), PSO, BBO, blended BBO and hybrid BBO-DE algorithms.

Findings

Experimental results indicate that the proposed algorithm outperforms the BBO, PSO, DE, GA, and the blended BBO algorithms and has comparable performance to that of the hybrid BBO-DE algorithm. However, the proposed algorithm is simpler than the BBO-DE algorithm since the PSO does not have complex operations such as mutation and crossover used in the DE algorithm.

Originality/value

The proposed algorithm is a generic algorithm that can be used to efficiently solve optimization problems similar to that solved using other popular evolutionary algorithms but with better performance.

Abstract

Purpose

The Covid-19 pandemic has profoundly affected urban communities, generating the need for an immediate response from local governance. The availability of urban data platforms in some smart cities helped the relevant actors to develop various solutions in an innovative and highly contextual way. The purpose of this paper is to explore the role of data platforms in smart cities in the context of the Covid-19 crisis.

Design/methodology/approach

A total of 85 studies were identified using the Clarivate Analytics Web of Science electronic library. After applying exclusion and inclusion criteria, 61 publications were considered appropriate and reasonable for the research, being read in-depth. Finally, only 52 studies presented relevant information for the topic and were synthesized following the defined research questions. During the research, the authors included in the paper other interesting references found in selected articles and important information regarding the role of data in the fight against Covid-19 in smart cities available on the Internet and social media, with the intention to capture both academic and practical perspectives.

Findings

The authors' main conclusion suggests that based on their previous expertise in collecting, processing and analyzing data from multiple sources, some smart cities quickly adapted their data platforms for an efficient response against Covid-19. The results highlight the importance of open data, data sharing, innovative thinking, the collaboration between public and private stakeholders, and the participation of citizens, especially in these difficult times.

Practical implications

The city managers and data operators can use the presented case studies and findings to identify relevant data-driven smart solutions in the fight against Covid-19 or another crisis.

Social implications

The performance of smart cities is a social concern since the population of urban communities is continuously growing. By reviewing the adoption of information technologies-based solutions to improve the quality of citizens' life, the paper emphasizes their potential in societies in which information technology is embedded, especially during a major crisis.

Originality/value

This research re-emphasizes the importance of collecting data in smart cities, the role of the diversity of their sources and the necessity of citizens, companies and government synergetic involvement, especially in a pandemic context. The existence of smart solutions to process and extract information and knowledge from large data sets was essential for many actors involved in smart cities, helping them in the decision-making process. Based on previous expertise, some smart cities quickly adapted their data platforms for an efficient response against Covid-19. The paper analyzes also these success cases that can be considered models to be adopted by other municipalities in similar circumstances.

Abstract

Purpose

The paper provides some fundamental observations on leadership from an Islamic perspective and the Islamic revealed knowledge. The purpose of this paper is to measure the association between Islamic leadership and the most common western forms of leadership namely; transactional, transformational, authentic, and ethical leadership styles as well as its relationship on leader’s effectiveness and organizational innovation.

Design/methodology/approach

An empirical investigation was conducted using portrait value questionnaire recommended by Schwartz (1994b), confirmatory factor analysis (CFA) followed by structural equation modelling (SEM).

Findings

The results indicated that Islamic leadership is positively and significantly associated with perception of leader effectiveness and innovation outcomes. In addition the findings revealed that Islamic leadership is positively correlated with transformational, ethical, and authentic leadership as well and not with the transactional leadership style.

Practical implications

Among the practical implications of this research is that while a large body of leadership research has adopted a variation of leadership theories, our results suggest that we should seize to pay attention to the influential Islamic leadership.

Originality/value

The originality of this paper is that it extends scholarly understanding on Islamic perspectives of management which is a relatively new and growing area of interest for academics and practitioners, in terms of both theory and practice.
