Abstract

Purpose

The purpose of this research is to develop a generic framework of a digital twin (DT)-based automated construction progress monitoring through reality capture to extended reality (RC-to-XR).

Design/methodology/approach

IDEF0 data modeling method has been designed to establish an integration of reality capturing technologies by using BIM, DTs and XR for automated construction progress monitoring. Structural equation modeling (SEM) method has been used to test the proposed hypotheses and develop the skill model to examine the reliability, validity and contribution of the framework to understand the DRX model's effectiveness if implemented in real practice.

Findings

The research findings validate the positive impact and importance of utilizing technology integration in a logical framework such as DRX, which provides trustable, real-time, transparent and digital construction progress monitoring.

Practical implications

DRX system captures accurate, real-time and comprehensive data at construction stage, analyses data and information precisely and quickly, visualizes information and reports in a real scale environment, facilitates information flows and communication, learns from itself, historical data and accessible online data to predict future actions, provides semantic and digitalize construction information with analytical capabilities and optimizes decision-making process.

Originality/value

The research presents a framework of an automated construction progress monitoring system that integrates BIM, various reality capturing technologies, DT and XR technologies (VR, AR and MR), arraying the steps on how these technologies work collaboratively to create, capture, generate, analyze, manage and visualize construction progress data, information and reports.

Abstract

Purpose

Climatic extreme events are predicted to occur more frequently and intensely and will significantly threat the living of residents in arid and semi-arid regions. Therefore, this study aims to assess climatic extremes’ response to the emerging climate change mitigation strategy using a marine cloud brightening (MCB) scheme.

Design/methodology/approach

Based on Hadley Centre Global Environmental Model version 2-Earth System model simulations of a MCB scheme, this study used six climatic extreme indices [i.e. the hottest days (TXx), the coolest nights (TNn), the warm spell duration (WSDI), the cold spell duration (CSDI), the consecutive dry days (CDD) and wettest consecutive five days (RX5day)] to analyze spatiotemporal evolution of climate extreme events in the arid Sahara-Sahel-Arabian Peninsula Zone with and without MCB implementation.

Findings

Compared with a Representative Concentration Pathways 4.5 scenario, from 2030 to 2059, implementation of MCB is predicted to decrease the mean annual TXx and TNn indices by 0.4–1.7 and 0.3–2.1°C, respectively, for most of the Sahara-Sahel-Arabian Peninsula zone. It would also shorten the mean annual WSDI index by 118–183 days and the mean annual CSDI index by only 1–3 days, especially in the southern Sahara-Sahel-Arabian Peninsula zone. In terms of extreme precipitation, MCB could also decrease the mean annual CDD index by 5–25 days in the whole Sahara and Sahel belt and increase the mean annual RX5day index by approximately 10 mm in the east part of the Sahel belt during 2030–2059.

Originality/value

The results provide the first insights into the impacts of MCB on extreme climate in the arid Sahara-Sahel-Arabian Peninsula zone.

Abstract

Purpose

This study aimed to investigate positive associations between three main motivations (social interaction, information and entertainment) for the use of social network sites (SNSs) and users' well-being, as well as the multiple mediating effects of perceived social support, positive and honest self-presentation.

Design/methodology/approach

A sample of 759 active users of SNSs (WeChat Moments, Qzone and Weibo) aged 14–43 years was measured with online questionnaires. Correlation analysis and structural equation modeling were implemented to examine the corresponding hypotheses.

Findings

The results showed the overall intensity of motivations was positively associated with users' well-being; perceived social support and positive self-presentation played intermediary roles and honest self-presentation and perceived social support had a chain mediation effect. However, the motivations of social interaction, information and entertainment indirectly affected users' well-being through three different mediation paths.

Originality/value

Although some studies have investigated the effects of motivations (including social interaction, information and entertainment) for SNS use on users' well-being, there has not been a consistent conclusion. The findings may shed light on the motivations for SNS use and how they may affect people's well-being in the digital era, thereby promoting their healthy use of SNSs as well as improved interface design and user management of SNSs.

Abstract

Purpose

This study aims to provide a comprehensive overview of the current state of the art in powder bed fusion (PBF) techniques for additive manufacturing of multiple materials. It reviews the emerging technologies in PBF multimaterial printing and summarizes the latest simulation approaches for modeling them. The topic of “multimaterial PBF techniques” is still very new, undeveloped, and of interest to academia and industry on many levels.

Design/methodology/approach

This is a review paper. The study approach was to carefully search for and investigate notable works and peer-reviewed publications concerning multimaterial three-dimensional printing using PBF techniques. The current methodologies, as well as their advantages and disadvantages, are cross-compared through a systematic review.

Findings

The results show that the development of multimaterial PBF techniques is still in its infancy as many fundamental “research” questions have yet to be addressed before production. Experimentation has many limitations and is costly; therefore, modeling and simulation can be very helpful and is, of course, possible; however, it is heavily dependent on the material data and computational power, so it needs further development in future studies.

Originality/value

This work investigates the multimaterial PBF techniques and discusses the novel printing methods with practical examples. Our literature survey revealed that the number of accounts on the predictive modeling of stresses and optimizing laser scan strategies in multimaterial PBF is low with a (very) limited range of applications. To facilitate future developments in this direction, the key information of the simulation efforts and the state-of-the-art computational models of multimaterial PBF are provided.

Abstract

Purpose

Sexual harassment is a pervasive and damaging issue that affects the physical and mental health and well-being of employees in the workplace. It is a serious public health concern that requires urgent attention and action and very dangerous problem in management. Our studies have shown that women are more likely to be the victims of sexual harassment and are more dissatisfied with the situation, organizations have a moral and legal obligation to take proactive measures to prevent and address sexual harassment, including implementing effective policies, providing employee training and fostering a culture of respect and accountability. By doing so, we can create safer, healthier and more productive work environments for all the employees.

Design/methodology/approach

This study consisted of 344 individuals from the Syrian community who completed a questionnaire, that contained statements about harassment to gauge each gender’s perception and sensitivity toward it. The questionnaire was carefully designed to include 30 questions, including daily situations in the work environment that may occur and how they are classified by males and females. Is it harassment or not, and about the HR department have personal safety and security standards such as the code of conduct and the rules regulating these behaviors or not and our research project was a collaboration between the two nongovernmental organizations (NGOs): Stemosis and Institute of Human Resources Management (IHRM).

Findings

Our research reveals a distinction between the thinking patterns and coping mechanisms of females and males when it comes to dealing with this phenomenon. We presented various scenarios to our respondents, depicting situations that an individual might face in their everyday life and asked them questions related to the definition of harassment, its root causes and strategies for addressing it. Research has shown that women are at a higher risk of experiencing feelings of fear and dissatisfaction when subjected to sexual harassment. This unfortunate reality highlights the need for greater awareness and action to combat such reprehensible behaviors. Save Women!

Research limitations/implications

The study faced several limitations in collecting data due to the sensitive and shameful nature of the topic for both men and women in the Syrian Arab Republic. This caused embarrassment for some participants, leading to their unwillingness to participate in the research. Additionally, the study encountered difficulties in dealing with companies, as they did not accept exposure to such situations and failed to show any codes of conduct under the name of their company, and the participants did not consider certain factors as reasons for harassment. Specifically, 71.2% of participants did not consider inappropriate outfits as a reason for harassment. However, there was a significant difference between the opinions of men and women on this matter (p-value < 0.05). Additionally, political, social and psychological reactions were not considered a reason for harassment by 64.8% of participants.

Practical implications

In our study, there was a situation that one of the respondents (male) was exposed to by the HR manager (female) who was pretending to be a professional, after he confronted her, she threatened him with expulsion from work and despite his annoyance, he ignored her because it was pointless to talk with her and during the study, (44.7%) of the participants had experienced sexual harassment.

Social implications

Victims of sexual harassment experience a similar condition to post-traumatic stress disorder, which can lead to many mental and psychological issues. The overall organizational environment plays a critical role in the well-being of employees. It is widely accepted that victims of violence suffer from a lack of well-being. Employee well-being is based on feelings of happiness and satisfaction that come from a sense of security. According to the Maslow’s theory of needs, security is fundamental to people and a toxic workplace environment can destroy an individual’s sense of security, negatively impacting their well-being In Syria.

Originality/value

In Syria, society is considered closed about sexual issues and considers it a sensitive issue despite its presence and spread in work environments, as the results showed, and this is one of the challenges we face. Therefore, our study is the first in Syria and the largest that sheds light on this phenomenon clearly, strongly, deeply and directly.

Abstract

Purpose

When improving business processes, process analysts can use data-driven methods, such as process mining, to identify improvement opportunities. However, despite being supported by data, process analysts decide which changes to implement. Analysts often use process visualisations to assess and determine which changes to pursue. This paper helps explore how process mining visualisations can aid process analysts in their work to identify, prioritise and communicate business process improvement opportunities.

Design/methodology/approach

The study follows the design science methodology to create and evaluate an artefact for visualising identified improvement opportunities (IRVIN).

Findings

A set of principles to facilitate the visualisation of process mining outputs for analysts to work with improvement opportunities was suggested. Particularly, insights into identifying, prioritising and communicating process improvement opportunities from visual representation are outlined.

Originality/value

Prior work focuses on visualisation from the perspectives – among others – of process exploration, process comparison and performance analysis. This study, however, considers process mining visualisation that aids in analysing process improvement opportunities.
