Circular construction offers sustainable solutions and opportunities to disentangle a project’s life cycle, including demolition, deconstruction and repurposing of architectural, civil engineering and infrastructure projects from the extraction of natural resources and their wasteful usage. However, it introduces additional layers of novel risks and uncertainties in the delivery of projects. The purpose of this study is to review the relevant literature to discover, classify and theorize the critical risk factors for circular construction projects.

The paper conducted a systematic literature review to investigate the risks of circular construction projects. It deployed a multistage approach, including literature search and assessment, metadata extraction, citation frequency analysis, Pareto analysis and total interpretive structural modeling.

Sixty-eight critical risk factors were identified and categorized into nine broad taxonomies: material risks, organizational risks, supply chain risks, technological risks, financial risks, design risks, health and safety risks, regulatory risks and stakeholder risks. Using the Pareto analysis, a conceptual map of 47 key critical risk factors was generated for circular construction projects. A hierarchical model was further developed to hypothesize the multiple possible connections and interdependencies of the taxonomies, leading to chain reactions and push effects of the key risks impacting circular construction projects.

This study constitutes the first systematic review of the literature, consolidating and theorizing the chain reactions of the critical risk factors for circular construction projects. Thus, it provides a better understanding of risks in circular construction projects.

While prior research has established that traumatic brain injury (TBI) is a risk factor for violent offending, there is little understanding of mechanisms that may underpin this relationship. This is problematic, as a better understanding of these mechanisms could facilitate more effective targeting of treatment. This study aims to address these gaps in the extant literature by examining TBI as a predictor of violent offending and test for mediation effects through cognitive constructs of dual systems imbalance and hostility among a sample of justice-involved youth (JIY).

The Pathways to Desistance data were analyzed. The first three waves of this data set comprising the responses of 1,354 JIY were analyzed. Generalized structural equation modeling was used to test for direct and indirect effects of interest. A bootstrap resampling process was used to compute unbiased standard errors for determining the statistical significance of mediation effects.

Lifetime experience of TBI was associated with increased violent offending frequency at follow-up. Hostility significantly mediated this relationship, but dual systems imbalance did not. This indicated that programming focused on reducing hostility among JIY who have experienced TBI could aid in reducing violent recidivism rates.

To the best of the author’s knowledge, this study was the first to identify significant mediation of the relationship between TBI and violent offending through hostility.

Under the background that engineering, procurement and construction (EPC) contracting model is introduced to adapt to the highly fragmented characteristics of prefabricated construction, the schedule management of general contractor is faced with the challenge of dynamic transmission and interaction of construction scheduling-related risk. The purpose of this paper is to develop the hierarchy of prefabricated construction scheduling-related risks from the perspective of the general contractor, and to analyze the transmission mechanism between risks. The paper also aims to further distinguish the difference of the impact degree of scheduling-related risks, and provide reference for formulating the strategy to alleviate the construction delay.

Based on a review of the literature on prefabricated buildings, this paper identifies 22 scheduling-related risks in construction from the perspective of the general contractor. Semi-structured interviews were then conducted to obtain experts' views on the interrelationships among these risks. Following this, their overall structure was determined by using a hierarchical structure established by using interpretive structural modeling (ISM), and Matrice d'Impacts Croisés Multiplication Appliqués à un Classement (MICMAC) technique was applied to classify them into four groups according to their driving and dependence powers.

The results indicate that the 22 scheduling-related risks in construction followed the inherent path of step-by-step transmission, and all of them could cause different degrees of delays in prefabricated construction. Among them, general experience in contracting projects, the use of emerging technologies and the completeness of the relevant standards and specifications were strong drivers of scheduling delays in construction, and should be prioritized by the general contractor in schedule management. The transitive link between scheduling risks can guide them in developing prevention strategies.

Data quality and reliability risks are the major drawbacks of semi-structured interviews. These were minimized by engaging experts with rich theoretical and hands-on experience in prefabricated construction projects. The hierarchical model only reflects static influence relationships, and so dynamic interactions among scheduling-related risks should be studied in future.

The primary value of this study is in its development of a hierarchical model by using the integrated ISM–MICMAC approach that reflects the interaction between scheduling risks in the construction of prefabricated buildings. The hierarchy of these risks and the results of a “driving-dependence power” analysis can guide the general contractor in taking targeted preventive measures to avoid scheduling delays in the construction of prefabricated buildings.

The purpose of this paper is to highlight suicide risk factors experienced by graduate students and postdoctoral scholars, and then outline suicide prevention strategies for these populations.

Through analysis of literature and application of theory, the authors use the diathesis-stress model and Joiner’s (2005) interpersonal theory of suicidality to outline suicide prevention strategies specific to graduate students and postdoctoral scholars.

The authors’ review of the literature and application of theory suggest that both individuals and groups can engage in suicide prevention strategies, specifically pertaining to reducing stressors unique to graduate students and postdoctoral scholars, as well as addressing feelings of thwarted belongingness and perceived burdensomeness that can lead to the development of suicidality within these populations.

Engaging in suicide prevention strategies can save lives and address the mental health conditions exhibited among graduate student and postdoctoral scholars.

The authors offer a synthesis of good practices addressing suicide risk factors and prevention with attention to the stress-diathesis model and Joiner’s (2005) interpersonal theory of suicidality toward reducing suicidality among graduate students and postdoctoral scholars.

The purpose of this paper is to examine the nature of cyberbullying and corresponding strategies being used under the New United Arab Emirates (UAE) Cybercrimes Law.

The analysis begins with a review of the nature of cyberbullying, focusing primarily on key concepts, underlying risk factors, forms of cyberbullying and adverse effects. Background information about the nature of cyberbullying will then lay the foundation for the subsequent sections of the analysis, which will focus on preventive strategies and legislative measures. The second section of the analysis will entail a review of the legislative framework for cyberbullying in the UAE. The goal here is to examine how the UAE is responding to the emerging threat of cyberbullying in its jurisdiction. The next section will then shift gears to interventions and strategies being implemented at the global level. A global perspective is central to comparing practices in the UAE to international standards and regulations.

Findings from the analysis have shown that the UAE has the most robust and comprehensive cyberbullying laws internationally. Nonetheless, the New Cybercrimes Law is ambiguous, and it is not expressively specific to cyberbullying. The law does not have a clear definition of cyberbullying, as well as the scope of its application to specific cases involving students. A comparative analysis across jurisdictions has revealed that most countries neither have specific cyberbullying laws nor explicitly define the phenomenon in existing laws. Thus, cyberbullying is a gray area in the UAE national law, requiring a clear definition and scope of application. The courts will establish case law that will finally address the current definitional challenges and extend of applying the New Cybercrimes Law.

The analysis concludes with the application of international best standards and practices to the UAE context, focusing specifically on how to strengthen laws and procedures in the UAE.

The purpose of the article is to provide further evidence for the work environment hypothesis. According to the work environment hypothesis and as documented by empirical evidence, organizational factors play a crucial role in the development of workplace bullying. However, to better understand and prevent bullying at work and establish sustainable, responsible and ethical workplaces, it is crucial to understand which organizational factors are particularly important in the development of bullying and how these factors, independently and combined, act as precursors to bullying over time. One prominent theory that explains how organizational and individual factors interact is the affective events theory (AET).

In a two-wave, time-lagged study (N = 364), the authors apply AET to test and explain the interplay of organizational factors in the development of bullying at work.

The results revealed that supportive and fair leadership moderates the relationship between role stress and exposure to workplace bullying.

Knowledge of the buffering role of supportive and fair leadership practices is important when implementing organizational interventions aimed at preventing bullying at work.

Although previous studies have shown the general protecting effects of supportive leadership on exposure to bullying, the current study indicates that high level of supportive and fair leadership practices decreases the level of exposure to bullying, even when role ambiguity and role conflict are relatively high.

This study explores the effect of income diversification strategy on credit risk and market risk of microfinance institutions (MFIs) in Ghana as an emerging market.

The study is based on quarterly data of averagely 271 MFIs that have operated from 2016 to 2018. The dataset is unbalanced and pooled cross-sectional with 3,259 data points. The study measures the diversification strategy using income diversification indices, and accounting ratios to measure the other variables. We utilised the weighted least squares (WLS) approach to explore the nexus.

The findings show that income diversification is associated with better loan quality and credit risk management. Market risk increases with the level of income diversification of microfinance firms. It is evident that large MFIs can manage their credit risks well and can have a low default rate, depicting an overall U-shaped nexus. On the other hand, the effect of size on market risk is an inverted U-shaped. The effect of asset tangibility on credit risk is positively significant while the effect on market risk is negatively significant. High profitability enhances credit risk management leading to lower loan losses while in the case of diversified and profitable MFIs, they tend to invest more in government securities. The results suggest that MFIs that hold more cash and cash equivalents tend to have high loan loss provision and more government securities suggesting much attention should be paid to optimal cash management.

The results throw light on the credit risk and market risk profile of the firms and the effect of diversification strategies on them. The findings are relevant for effective macroprudential regulation, market regulation and prudential regulation of the microfinance sector.

The findings reveal the nature of income diversification strategy of MFIs in emerging markets such as Ghana, pointing out how they affect the risk exposure of MFIs that lend to the pro-poor population.

This is a premier formal assessment of the nexus between income diversification strategies and risk management among MFIs that serve the pro-poor population in the emerging market context.
