Abstract
Purpose
The present study aims to investigate the psychometric properties of the picture story exercise (PSE), a tool for measuring implicit motivations in Iran.
Design/methodology/approach
The research method is descriptive correlation and was conducted in two studies. In the first study 24 psychology master’s students were selected by convenience sampling method and tested them to check retest and inter-coder reliability. The second study investigated the correlation between self-reports and the PSE test on a sample of managers. Its statistical population comprised all the managers of a refinery company, 50 people were selected by convenience sampling method. To check the concurrent validity of the PSE test, the participants of the second study, completing the PSE, also completed the needs questionnaire of Steers and Porter (1979).
Findings
The findings showed that the PSE test in the Iranian sample had high retest reliability (0.62 on mean) and inter-coder reliability (0.87 on mean), and, following previous research, it does not show a significant relationship with self-reported motives.
Practical implications
PSE can be used in future research as a tool that has demonstrated its reliability and validity in the Iranian sample.
Originality/value
Measurement of implicit motives is a practical factor for predicting people’s behavior, the necessity of using tools that can accurately evaluate implicit motives is strongly felt. Taking into account the fact that so far, in Iranian samples, implicit motivations have not been measured, therefore, the current research is trying to answer this question, whether one of the most important and prominent tools that were made for this purpose and used in various studies can also be used in Iranian samples.

Abstract
Purpose
Despite the availability of amicable means to resolve construction disputes, litigation remains a mainstream dispute resolution process in some countries. This tendency to litigate (TTL) calls for research to develop appropriate precautions to encourage stakeholders to resolve most commercial disputes through alternate dispute resolution (ADR) techniques. While a claimant's TTL arise from the individual, project and organisation preferences, this study, which can benefit both potential claimants and employers by saving time and money on litigation, identifies a bidder's financial parameters that may increase its litigation propensities, as a first step towards aiding employers to incorporate precautions to discourage such tendencies.
Design/methodology/approach
After the literature review, the theoretical construct proposed by Rachlinski's “framing theory of litigation” (based on Kahneman and Tversky's Prospects Theory) is used to explain organisation-level litigation decision-making. The study sources data from the financial statements of Indian construction/real estate firms, followed by panel regression analysis to test the theoretical construct's validity.
Findings
The results show that the TTL (risk-seeking behaviour) generally increases with a lower value of sales, higher assets and profitability. Interestingly, organisation-level cash flow shows an insignificant influence on litigation tendencies.
Practical implications
Knowing which financial parameters may increase litigation tendencies could help employers evaluate a bidder's propensity to litigate project disputes.
Originality/value
Researchers use financial statements to explore correlations among financial variables. However, in the construction context, there are no empirical studies with data from construction firms to understand potential litigation expenses compared to specific financial ratios.

The purpose of this study is to present a general review that provides an overview of the concept of sustainability and the effectiveness of mathematics curricula in courses where deeper work on economic and environmental sustainability has become central.
Design/methodology/approach
A qualitative methodology consisting of a review based on a pre-defined systematic method was used to exhaustively search and identify the most relevant answers to the research question: What is the role of mathematics to sustainability? To facilitate answering such a broad question, several concrete questions were formulated. Answers from published and unpublished documents were analysed. The quality of the extracted data was assessed, and the results were synthesized.
Findings
It was concluded that, on the one hand, the discipline of mathematics has much to contribute to solving the problems of sustainability; on the other hand, new mathematics is appearing stimulated by new challenges.
Social implications
This work presents social implications in an innovative way. It allows for an increase in educational sustainability by bringing the academic community closer to the business world and the challenges of society and, furthermore, by having a major impact on the motivation of teachers and students to develop cooperative work within university institutions.
Originality/value
The originality is based on an a priori analysis for the construction and implementation of didactic tools for university teacher training in the area of mathematics within the framework of sustainable development, both economically and environmentally.

Abstract
This chapter analyzes the link between the digital divide, infrastructure regulation, and disaster planning and relief through a case study of the flood in San Jose, California triggered by the Anderson dam’s overtopping in February 2017 and an examination of communication failures during the 2018 wildfire in Paradise, California. This chapter theorizes that regulatory decisions construct social and disaster vulnerability. Rooted in the Whole Community approach to disaster planning and relief espoused by the United Nations and the Federal Emergency Management Agency, this chapter calls for leadership to end the digital divide. It highlights the imperative of understanding community information needs and argues for linking strategies to close the digital divide with infrastructure and emergency planning. As the Internet’s integration into society increases, the digital divide diminishes access to societal resources including disaster aid, and exacerbates wildfire, flood, pandemic, and other risks. To mitigate climate change, climate-induced disaster, protect access to social services and the economy, and safeguard democracy, it argues for digital inclusion strategies as a centerpiece of community-centered infrastructure regulation and disaster relief.

Abstract
Relying on Social Identity Theory (SIT), Relative Deprivation Theory (RDT) and System Justification Theory (SJT), this study aims at examining identity enhancement strategies of blue-collar workers who might be described as members of low-status groups having negative social identity. In the scope of this study, individual and collective strategies for identity enhancement of blue-collar workers have been proposed with the support of above mentioned theories. First of all, factors determining identity enhancement strategies have been described. Then, individual mobility conditions were explained and informal workplace learning was suggested as an individual mobility strategy for blue-collar workers to enhance social identity. In addition, it was argued that high self-monitoring blue collars are more likely than low self-monitoring blue collars to use individual mobility strategy. It was also emphasized that through union membership, high identifier blue collars will adopt a collective identity enhancement strategy. Finally, acceptance of low-status strategy was proposed for blue-collar workers in case they perceive their group’s low status as stable and legitimate.

Abstract
Purpose
The purpose of this paper is to propose a distributed unmanned aerial vehicle (UAV) swarm control method to ensure safety and obstacle avoidance during swarm flight and realize effective guidance.
Design/methodology/approach
This paper proposes a distributed UAV swarm control framework with limited interaction. UAVs in the swarm realize the selection of limited interactive neighbors according to the random line of sight and limited field of view. The designed interaction force and obstacle avoidance mechanism are combined to ensure the safety of UAVs and avoid collisions and obstacles. Informed UAVs are deployed to guide the swarm to move in the desired direction.
Findings
The proposed distributed swarm control framework achieves high safety of swarm motion and the participation of informed UAVs is conducive to the guidance of the UAV swarm. Simulation results demonstrate the feasibility and effectiveness of the proposed approach.
Practical implications
The UAV swarm control method developed in this paper can be applied to the practice of UAV swarm control.
Originality/value
A distributed UAV swarm control method is proposed to ensure the effective control of the consistency and safety of swarm motion.

Abstract
Purpose
This study explores whether and how Internet usage improves the subjective health of middle-aged and older adults by analyzing the mediating role of social engagement and heterogeneity of different living arrangements.
Design/methodology/approach
Based on data from the China Health and Retirement Longitudinal Study, the ordinary least squares (OLS) method is adopted to explore the relationship between Internet usage and the subjective health of middle-aged and older adults. Propensity score matching method (PSM) is used to alleviate self-selection bias in the samples. The bootstrap method is adopted to test the mediating role of social engagement, and generalized structural equation modeling (GSEM) is employed to resolve endogeneity. A permutation test is adopted to examine the heterogeneous effects of Internet usage on different living arrangements.
Findings
Internet access can help relieve depression among middle-aged and older adults and enhance their self-rated health, leading to perceived changes in health status. However, Internet usage is not directly associated with health satisfaction among middle-aged and older adults. Nevertheless, Internet usage can enhance middle-aged and older adults' subjective health by facilitating social engagement and significantly influences middle-aged and older adults living with their children.
Originality/value
This study reveals the underlying role of Internet usage among older adults and provides insights for governments and families to help middle-aged and older adults actively adapt to a digital society and improve their health.
