- Description: Abstract: Construction is a dangerous industry globally, with high rates of fatal and non-fatal injuries. However, there is paucity of analytical research that considers the predicators of injuries among construction workers in South Africa construction industry and in the developing countries. The objective of this study was to review existing research literature to identify the variables that are predictors of occupational injuries among construction workers. It also aimed to identify the gaps that exist in the current literature. The review spanned two decades between the periods January 1995 to 2015 and was based on a systematic keyword combination search in two databases that is- emerald a! nd science direct and in google. Twenty one quantitative and mixed method research studies were justified to be relevant for analysis in this current study. They were analysed using thematic content analysis, by identifying themes. All the studies reviewed had different predictors of construction workers injury. Furthermore, no study identified the leadership characteristics of the different construction workers especially the tradesmen, hence these are major gaps identified in the current literature. Despite the gaps identified, five broad themes that are perceived to be predictors of construction workers injuries were identified, these are: work related variables, demographic variables, unsafe health and safety (H&S) behaviour, poor safety climate, and psychosocial factors. This paper finally proposed a conceptual model for construction worker injury occurrence.

- Description: Abstract: The competitive nature of the construction industry (CI) has marginalised health and safety (H&S) on construction projects. Most clients in the CI, if not all, award projects based on price and in most cases to the “cheapest bidder” and not the “safer bidder”. Consequently, such practices have compelled contractors to lower their bid price to increase their chances of being awarded projects, whereas in contrast, H&S is marginalised. The study, which was a case study of nine projects of which six were civil engineering projects and three building construction projects, was purposed to conceptualise a model for pricing H&S on construction projects. The findings showed that contractors do price for H&S using an itemised breakdown even though such items are not included as a trade in the Bill of Quantities (BOQs). With regards to expenditure, the actual costs of H&S ranged between 2.9% and 3.98% for projects with a value below R500 million and between 4.08% and 4.90% for projects with a value above R500 million. Health and safety costs were found to be directly proportional to the projects value and indirectly influenced by the client. Previous studies recommended that H&S should be priced as an itemised trade in the BOQs, but such recommendations are yet to be implemented. The lack of a conceptual model for pricing H&S on construction makes accurate and adequate monitoring of H&S costs unlikely. Thus, a standardised pricing model will assist contractors to price adequately for H&S, and clients, to ensure that provision for H&S measures on construction projects is adequate as required by the Construction Regulations (CR) 2014.

- Description: Purpose: This paper presents a conceptual six factor client H&S culture model referred to as the LIP+3C. The factors leadership, involvement, procedures, commitment, communication and competence were theorised to explain the client H&S culture construct. The postulated model is based on theory obtained from literature as well as from a Delphi research. H&S culture has been recognised as the feasible way to improve H&S performance in the construction industry. Design/methodology/approach: A Delphi study as well as a synthesis of literature was conducted and resulted in a theorised conceptual model. To validate the model, a questionnaire survey with a response of 281 was conducted. Findings from the questionnaire survey were analysed using Structural Equation Modelling (SEM) with EQS version 6.1 software. Findings: The six factor client H&S culture model was found to be well fitting to the sample data through the confirmatory factor analysis. Consequently client H&S culture findings were that client culture could be explained by the level of leadership, involvement, procedures, commitment, communication and competence. Research limitations/implications: The size of the sample may affect the generalisability the findings in view of the complexity of the model. Practical implications: The proposed model in this study makes it possible to determine and predict the client H&S culture. The indicator variables can be used as check items for performance measurement and thus operationalize the concept of H&S culture. Originality/value: Adopting the LIP+3C culture model composed of elements that can easily be implemented and understood will contribute to improving the current H&S status

- Description: Abstract: Outsourcing is a subject of much attention and controversy in the modern business landscape, due to far-reaching ramifications into matters such as politics, economics, legal, and human resources. Given such wide exposure, ensuring the success of outsourcing projects seems a worthwhile pursuit. This paper presents a study focused on Information Technology (IT) outsourcing, which entails full or partial transfer of ownership of IT-related processes to a vendor, supposedly to achieve business benefits such as cheaper costs, economies of scale, and increased efficiency. This said, can all processes be outsourced? Are some processes meant to be kept in-house? To what extent do the overarching strategies and motivations behind an outsourcing decision influence the outsourcing delivery models and eventually the performance of outsourcing projects? Regardless of the specifics of an outsourcing project, there seems to be a dearth of tried, tested and repeatable blueprints guiding the decision-making throughout the outsourcing journey. The aim of this paper is two-fold: a) Present the finding of a study towards a conceptual model for IT outsourcing; b) Illustrate how a conceptual model can be validated with empirical data, towards an enhanced model; Data was collected from 20 outsourcing professionals via structured questionnaire derived from the conceptual model for successful outsourcing. Data was then analysed through data visualization and findings were contrasted against the initial literature review. Knowledge gaps identified were applied to the conceptual model and the enhanced model was proposed as a result.

- Description: The purpose of the study was to evaluate an extended conceptual model depicting hypothesised relationships between employee climate, customer value and financial performance. Questionnaires assessing employee experienced climate and customer-experienced value were completed by all the employees (more than 1200) and more than 2000 customers of a single retail company operating almost 100 stores in Southern Africa. The major findings were that some of the components of employee-experienced climate are positively related to customer experienced value in terms of both product and relationship quality. There was no significant relationship between customer-experienced value and the financial performance of the organisation.
