Confirmatory Factor Analysis of Performance Measurement Indicators Determining the Uptake of CPS for Facilities Management

Business environment as a determinant in the uptake of cyber-physical systems for facilities management – a Delphi study

Purpose

Incorporating digital technologies such cyber-physical systems (CPS) for facilities management (FM) functions is fast gaining attention. However, the rudiments for the effective espousal of such an innovative technology for the delivery of FM tasks have not received scholarly attention. In FM, the business environment is a vital component in achieving organisations’ stipulated objectives. Hence, this study aims to assess the influence of business environment factors in the adoption of CPS for FM activities.

Design/methodology/approach

A qualitative approach was adopted for the study using the Delphi technique. Experts were selected through a well-defined process that involved certain criteria. The opinions of the selected experts were gotten in two iterations that were subjected to analysis using statistics of measure for central tendency, and interquartile deviation to ascertain consensus among the experts, while Mann–Whitney U test was deployed in checking the difference in the views of the experts.

Findings

The results from the study indicated that eight business environment factors were of very high significance in determining the espousal of CPS for FM, while the other eight factors proved to be high significance. Also, there was no significant difference in the opinions of experts from academic institutions and professional practice.

Practical implications

The findings from the study would provide insight to organisations saddled with FM activities on the prevailing business environment factors that would be influential in adopting a digital technology such as CPS.

Originality/value

The study contributes immensely to the body of knowledge in the quest for digital transformation in FM delivery. It unveils the significant business environment factors that are influential in the drive for incorporating new innovations such as CPS for FM functions.

Validation of a Scale on Society's Attitudes towards the Sexuality of Women with Intellectual Disabilities-Survey Study

BACKGROUND

The main aim of this study was to design and validate a questionnaire in Spanish to acknowledge the perception of the sexuality of women with intellectual disabilities. We sought to cover specific spheres of sexuality, such as sexual capacity, decision-making capacity, sexual disinhibition, and sexual education and quality of life.

METHODS

A questionnaire was developed based on a literature review. Validation was performed using content validation through a panel of experts; construct validation was performed using exploratory and confirmatory factorial analyses; reliability tests were also performed, using Cronbach's Alpha and the two-halves test.

RESULTS

Two-hundred forty-four participants pilot tested the initial 34-item questionnaire. After content validation and exploratory factorial analysis, the resulting 10-item questionnaire showed four domains, with Cronbach's Alpha values between 0.69 and 0.82. Confirmatory factorial analysis confirmed the domains, and the model's goodness-of-fit tests were adequate.

CONCLUSIONS

The final ten-item scale developed in this research proved to be a valid and reliable instrument, as it has good psychometric properties of both validity and reliability. Thus, researchers interested in investigating the social perception of the sexuality of women with intellectual disabilities can use this tool. Future research can extend the validity of this scale to other languages and settings.

Barriers to Digital Technology Deployment in Value Management Practice

In the quest to promote constant value for money, value management (VM) has been proposed and adopted within the construction industry of countries across the world. To improve the VM process for a more effective outcome, pervasive digital technologies can be employed throughout a project and in the VM process. However, developing countries like South Africa are still lagging in using these emerging technologies. Therefore, this study assessed the digital technologies that can improve the VM process and the barriers hindering their usage within the construction industry. The study adopted a postpositivism philosophical stance with a questionnaire used to gather quantitative data from construction professionals that have participated in VM exercises within the South African construction industry. The data gathered were analysed using mean item score, standard deviation, the Kruskal-Wallis H-test, multiple linear regression and exploratory factor analysis. The study found with high predictive accuracy that digital technologies such as computer-based software, BIM, mobile devices, electronic meeting tools, cloud computing, augmented and virtual realities will significantly impact the overall success of VM practices. Furthermore, the barriers to the effective deployment of these technologies in the VM process can be categorised into (1) cost and awareness, (2) complexities of the VM and digital tools, (3) the construction industry’s digital culture, and (4) the availability of technology and expertise. This study provides a theoretical backdrop for future studies exploring the use of digital technologies for VM practices—an aspect that has not gained significant attention in VM discourse in the construction industry.
