The purpose of this study is to investigate the usage of digital technologies (DTs) in improving the mental health of workers on construction sites.

A mixed research approach was used in the study, which comprised a questionnaire survey and two phases of semi-structured interviews. Purposive sampling was used to determine the interviewees and respondents of the questionnaire survey. Weighted mean rating (WMR) and manual content analysis were used to rank and evaluate the collected data.

The findings of this study revealed bipolar disorder, anxiety disorders, attention-deficit/hyperactivity disorder, obsessive-compulsive disorder, work-related stress and depression as the six most significant mental disorders (MDs) among the construction workforce and 30 causes for them. Moreover, 27 symptoms were related to the six most significant MDs, and sweating was the most significant symptom among them. Despite that, 16 DTs were found to be suitable in mitigating the causes for the most significant MDs.

There are numerous studies conducted on the application of DTs to construction operations. However, insufficient studies have been conducted focusing on the application of DTs in improving the mental health of workers at construction sites. This study can thus influence the use of DTs for tackling the common causes for MDs by bringing a new paradigm to the construction industry.

Changes frequently made to material delivery schedules (MDSs) accumulate upstream in the supply chain (SC), causing a bullwhip effect. This article seeks to elucidate how dynamic complexity generates MDS instability at OEMs in the automotive industry.

An exploratory multiple-case study methodology involved in-depth semistructured interviews with informants at three automotive original equipment manufacturers (OEMs).

Dynamic complexity destabilizes MDSs primarily via internal horizontal interactions between product and process complexities and demand and SC complexities. A network of complexity interactions causes and moderates such instability through complexity absorption and generation and complexity importation and exportation.

The multiple-case study contributes to empirical knowledge about the dynamics of MDS instability. Deductive research to validate the identified relationships remains for Future research.

In revealing antecedents of complexity’s effect on MDS instability, the findings imply the need to develop strategies, programs, and policies dedicated to improving capacity scalability, supplier flexibility, and the flexibility of material order fulfillment.

Building on complexity literature, the authors operationalize complexity transfer and develop a framework for analyzing dynamic complexity in SCs, focusing on complexity interactions. The identification and categorization of interactions provide a granular view of the dynamic complexity that generates MDS instability. The identified and proposed importance of readiness of the SC to absorb complexity challenges the literature focus on external factors for explaining complexity outcomes. The results can be used to operationalize such dynamic interactions by introducing new variables and networks of relationships. Moreover, the work showcases how a complexity perspective could be used to discern the root causes of a complex phenomenon driven by non-linear relationships.

This paper aims to evaluate the socio-economic factors of inequalities in common mental disorders (MDs) between advantaged and disadvantaged groups and also to determine the main contributors of inequality.

This cross-sectional study was conducted in 2016–2017. The authors included 763 persons by stratified cluster sampling; clusters were cities, geographical area and households. Blinder-Oaxaca decomposition technique was used to estimate of main inequalities determinant between advantaged and disadvantaged groups.

Overall prevalence of MDs was 22.6 and 35.6% in the advantage and disadvantaged groups, respectively. The concentration index was −0.013 [95% Confidence Interval (95% CI): −0.022, −0.004]; therefore, MDs were more concentrated in the deprived group. The risk of MDs in deprived group and females was 81 and 60% higher than advantaged group (OR: 1.81; 95% CI: 1.28, 2.57) and males (OR: 1.60; 95% CI: 1.21, 2.24), respectively. Educational status [−0.06 (95% CI: −0.10, −0.01)] was the highest level of contribution in inequality in gaps between groups.

The socio-demographic inequality in MDs among adult population was more explained by lower educational level, married persons and unemployment variables.

This chapter addresses one aspect of the broad issue of the psychological foundations of the dimensions of multidimensional scaling (MDS) solutions. Using empirical data from three independent studies, it is shown that the dimensionality of MDS solutions is negatively related to individual differences in the level of cognitive differentiation and integrative complexity of individuals and positively related to the individual's ability to discriminate within dimensions. MDS dimensionality is also shown to be affected by a variety of task-related variables such as perceived task difficulty, consistency in providing similarity judgments, confidence, familiarity, and importance attached to the stimuli. The chapter concludes by raising the issue of whether MDS can be validly used to describe complex cognitive processes.

This study analyzes in-depth how knowledge-intensive small and medium-sized enterprises (SMEs) can achieve higher new product development (NPD) process performance in the epidemic era and examine the internal development mechanism of knowledge-intensive SMEs in the process of continuous digital transformation.

This issue is tested with partial least squares on data collected via a survey conducted from November 2021 to February 2022. The sample comprises 487 knowledge-intensive SMEs operating in China.

The results indicate that one form of cross-functional ambidexterity, market development strategy (MDS), plays an important role in process performance from an inside-out financial perspective and an outside-in customer perspective. Simultaneously, product innovation efficiency (PIE) mediates the relationship between MDS and the above results. Big data analytics capabilities (BDACs) positively regulate the relationship between MDS and PIE.

The authors do not consider other contingency factors. Future research should introduce influential factors such as leadership and competitive intensity to further distinguish the effects of MDS on NPD process performance.

The study findings offer suggestions to help knowledge-intensive SME managers better manage their NPD process by making better use of their limited resources in developing countries such as China.

This study is one of only a few to adopt a process-oriented perspective to specifically examine how one form of cross-functional ambidexterity, MDS, impacts knowledge-intensive SME process performance in the epidemic era. This study also extends the theoretical framework of cross-functional ambidexterity to BDAC research.

This study aims to examine the potential influence of multiple directorships (MDs) on the firm value of listed firms in Jordan.

Using a sample of 1,067 firm-year observations of Jordanian listed companies from 2010 to 2020, this study applies a pooled ordinary least squares regression model to examine the above-stated relationship. This technique was supported by conducting a generalized method of moments estimation to address the possible occurrence of endogeneity concerns.

The results show a significant negative relationship between MDs and firm performance, thereby supporting the “Busyness Hypothesis”, which suggests that directors with MDs are expected to be over-committed, too busy and less vigilant. Thus, their ability to effectively monitor the company management on behalf of the shareholders is quite limited.

To the best of the authors’ knowledge, this is the first study in Jordan, and one of the very rare studies in the Middle Eastern and North African region, to examine the relationship between MDs and firm performance. This study provides important policy and practitioner implications in the field of corporate governance by highlighting the necessity of imposing stricter limits on the number of directorships allowed for board directors. Crucially, the empirical evidence implies that limited directorships ensure that directors are able to fulfil their board responsibilities appropriately, which is significantly associated with the firm value.

Wireless network localization technology is very popular in recent years and has attracted worldwide attention. The purpose of this paper is to improve the localization accuracy of ultra-wideband (UWB) with lower localization error taking into consideration the special real environment with the closed long and narrow space.

The principle of multidimensional scaling (MDS), particle swarm optimization (PSO) and Taylor series expansion algorithm (Taylor-D) were introduced. A novel positioning algorithm, MDS-PSO-Taylor was proposed to minimize the localization error. MDS-PSO algorithm provided a more accurate preliminary coordinate by applying the PSO algorithm so that the Taylor-D was used for further enhancing the localization accuracy.

Experimental results manifested that the proposed algorithm, providing small localization error value and higher positioning accuracy, can effectively reduce errors and achieve better performance in terms of the considerable improvement of localization accuracy.

The presented study with the real environment test attempts to demonstrate the proposed algorithm is hopeful to be applied to the underground environment for in the future.

This article is based on a paper presented at an international conference in Norway. Having read in ICT about the work of the Small Firms Management Centre at the Sheffield Polytechnic, Gary Hansen wrote to us to tell us about similar work underway in the US.

The purpose of this paper is to examine the structure of juvenile psychopathy, as measured by the Psychopathy Checklist: Youth Version (PCL: YV).

Using a sample of 2,042 male youths from the USA, Canada, and the UK, the study was a conceptual replication of Bishopp and Hare’s (2008) multidimensional scaling (MDS) analysis of adult male offenders assessed with the Psychopathy Checklist-Revised.

The scaling analyses generally replicated those obtained by Bishopp and Hare, providing support for a multidimensional, four-factor model of juvenile psychopathy similar to that obtained with adults. However, a small number of items fell outside their predicted regions. Slight differences in the structure of juvenile psychopathy were found for incarcerated and supervised samples of youth, with the four-factor model breaking down slightly for the supervised sample. Item misplacements may indicate that certain items on the PCL: YV are being misinterpreted, reflect different dimensions for different samples, or cannot be reliably measured. Future research should examine these possibilities, with special attention being paid to supervised samples.

To the authors’ knowledge, this is one of the first known attempts to use MDS analysis to examine the psychopathy structures that emerge for male juvenile offenders. The greater nuances afforded by using MDS offer a more comprehensive understanding of psychopathy between incarcerated and supervised youth using the PCL: YV.

This paper investigates the ways managing directors (MDs) in small and medium-sized enterprises (SMEs) involve employees in strategic conversations. The paper examines how managers interact with employees in strategic conversations, and why the managers do so (or do not), to generate empirically grounded knowledge about the nature of internal openness in SMEs.

This study employs a general inductive approach and is based on in-depth interviews with 60 Swedish MDs with development and growth ambitions.

The paper develops a model of employee involvement in strategic conversations based on the nature and intensity of the MD–employee interaction. A key finding is that SMEs exhibit wide variation in terms of employee involvement, from virtually no employee involvement to, in some cases, far-reaching company democracy. The reasons for this variation are complex, but personal preferences and company size are shown to have an impact, as does, to some degree, ownership structure. In contrast to existing research, the limitations and drawbacks of involving employees in strategic conversations are outlined.

The study provides important insight into MDs' views and practices of internal openness in strategic conversations in SMEs. A model of employee involvement in strategic processes is outlined, and potential limitations of internal openness are highlighted.
