An analysis of the mediational effect of socio-cultural factors on student’s career choice outcomes in the built environment: applying the socio-cognitive career theory

Investigations into career development revealed the significant influence of social and cultural determinants, notably familial factors, on children’s professional aspirations. Such aspirations are moulded by their milieu, individual interests, academic environments, and socio-economic contexts. South Africa’s unique socio-political history introduces complexity into career development pathways. The intricate relationships between ethnicity, gender, and socio-economic backgrounds vis-a-vis career outcomes of South African youth remain underexplored. This research aimed to understand these influences within the construction domain, emphasising cognitive facets such as self-efficacy and societal endorsements. The Social Cognitive Career Theory (SCCT) served as the foundational framework, with structural equation modelling employed for causal analysis. A focus was given to early university students, predominantly from Construction Management. The study showcased pathways for informed career decisions in construction and underscored the relevance of the SCCT, especially for women in traditionally male-dominated sectors. The study culminated in unveiling pathways for informed career decisions in construction, reinforcing the pertinence of the SCCT framework, especially concerning women in traditionally male-dominated spheres like construction. Acknowledging the scarcity of empirical studies using SCCT within the construction sphere is pertinent

The private versus public infrastructure in Sub-Saharan Africa: An empirical validation

The macroeconomics of the relationship between the private and public infrastructure in sub-Saharan Africa has been very unpredictable due to the region’s ineffective planning and policy formulation for infrastructure and service delivery. This paper examines the relationship between public and private infrastructure in subSaharan Africa. It also demonstrates that sub-Saharan Africa consumes more and invests less when compared to the industrialised world and that the present domestic investments in sub-Saharan Africa are actually more in the hands of the private sector. Lastly, an inference relationship for measuring and comparing economic stability between countries and regions was formulated, with the industrialised countries as a reference value.N/

Green construction in India: gaining a deeper understanding

A workshop on green construction was organized in New Delhi in July 2008 by Jamia Millia University, India and University of Salford, U.K., aiming to increase 'green' practices that are environmentally friendly and energy efficient. The workshop included participants from regulatory bodies, public and private construction companies and researchers. The object of the workshop was to provide an opportunity to capture issues, challenges and research issues in green practices throughout the supply chain in the construction sector in India. The methodology constituted a survey that was provided to all participants, where eight questions were composed by the facilitators. The participants were asked about their views on voluntary and compulsory ways of assessment and audit of green implementation in India. The findings of the workshop featured major challenges, drivers, initiatives, and the ways of effective implementation as well as enforcement on the discussed topic

Regeneration of Sub-Saharan Africa’s open market places: a case for Guileless stakeholder participation

Sub-Saharan Africa’s urban culture makes open marketplaces an essential part of life in their cities. What goes on in these markets undoubtedly opens them up to threats of adversity, tragedy, and other significant sources of stress. How can these open marketplaces be regenerated into resiliently sustainable places? From a case study of the regeneration redevelopment of the largest open-air market in West Africa i.e. Kumasi Central Market, the need for stakeholder participation in the entire regeneration process is emphasised. The determination of the most important stakeholders during the regeneration of the market is followed by a comparison of the regeneration process regeneration with the literature on urban regeneration, sustainable development, participation, and project management. Lessons learned, and the concerns raised by major stakeholders in the process creates certain project management approaches essential for achieving resilient urban regeneration. Identification of all important stakeholders by the consideration of their attributes of power, legitimacy and urgency and distrustfully engaging all stakeholders is vital to the success of any urban regeneration project

Modelling in ranking procedures: A case study of infrastructure failures in Nigeria

The lack of a scientific approach as to which factors are considered or chosen in a decision-making process can seriously influence the effectiveness of that process. Using the example of infrastructure failures in Nigeria, this paper presents a severity index in matrix order (SIMO) model that unambiguously ranks factors and also defines a threshold that demarcates between major variable factors that should not be compromised in policy and less important ones. Infrastructures failures in Nigeria have hindered economic processes which were meant to alleviate poverty. Constraints responsible for this situation are identified from a carefully conducted survey in Nigeria. Severity of these constraints is empirically ranked using a developed severity index in matrix order (SIMO) model. However, the investigation reveals that corruption, misallocation of investments, inadequate maintenance, lack of transparency and accountability, insufficient funding for infrastructure, lack of supportive institutions, inconsistent political, social and economic policies and the lack of suitable technical and managerial skill are the major variable factors responsible for infrastructure failures in Nigeria.N/

Effect of indoor environmental quality on visual comfort and productivity in office buildings

This is an accepted manuscript of an article published by Emerald in Journal of Engineering Design and Technology on 15/11/2021, available online: https://doi.org/10.1108/JEDT-09-2021-0474 The accepted version of the publication may differ from the final published version.Purpose: The Purpose of this paper is to identify statistical relationships between visual environment and occupant productivity. Visual environment is one of the most important indoor environmental quality (IEQ) parameters, and it directly impacts occupant productivity in offices. The literature outlines the significance of the impact. Still, there is a lack of investigation, statistical analysis and inter-relationships between the independent variables (IEQ factors), especially in the hot and arid climate. Design/methodology/approach: This study presents a research study investigating the effects and shows statistical relationships between IEQ on occupant comfort and productivity. The study was conducted in the Middle East, and data was collected for 12 months. It used the response surface analysis to perform analysis.

Identifying the Barriers to Sustainable Management of Construction and Demolition Waste in Developed and Developing Countries

The construction industry is a vital part of every nation’s economy. Construction activities influence the social, environmental, and economic aspects of sustainability. There are so many barriers to sustainable construction and demolition waste management (C&DWM). This study aims to identify barriers for effective sustainable C&DWM in developed and developing countries. To achieve the objective, 11 barriers have been selected and identified based on an excessive and comprehensive literature review, and then reviewed by experts. These reviewed barriers were further examined by various experts within different organizations using a questionnaire survey. Ranking of the barriers was carried out using the Relative Importance Index (RI), and the results were statistically analyzed using Statistical Package for Social Sciences (SPSS). Practical solutions were proposed to overcome the identified barriers. The overall ranking of barriers by RI indicates that insufficient attention paid to C&DWM, lack of law enforcement, lack of regulation, and financial constraints represent the four major barriers to sustainable C&DWM in these countries. The findings of this study and the proposed solutions are enablers for decision-makers to develop effective strategies to tackle construction and demolition wastes in sustainable manners

Effect of thermal comfort on occupant productivity in office buildings : response surface analysis

Thermal environment is one of the main factors that influence occupants' comfort and their productivity in office buildings. There is ample research that outlines this relationship between thermal comfort and occupant productivity. However, there is a lack of literature that presents mathematical relationship between them. This paper presents a research experimental study that investigates effects of indoor environmental quality factors on thermal comfort and occupant productivity. This study was conducted by collecting indoor environmental quality parameters using sensors and online survey for twelve months. Data analysis was done using Response Surface Analysis to outline any mathematical relationship between indoor environmental quality and occupant productivity. The outlined relationships confirmed dependencies of occupant thermal comfort and productivity on various indoor environmental factors. These dependencies include the effect of CO2 concentration, VOC concentration. These relationships were analysed to rank nine indoor environmental parameters as per the degree of effect on occupant thermal comfort and productivity. These findings would help design professionals to design better office design that would improve occupants’ comfort and their productivity. Study results have different implications for professionals working in design, construction and operation of office buildings. It is recommended that design guidelines for office buildings should consider occupant productivity and incorporate recommended range for indoor environmental quality parameters in respective categories and criteria
