Although the consequences of illicit financial outflows on the economies of the world continue to exert adverse impacts on many economies of the world, explanations regarding specific drivers of the illicit outflows remain divergent in the literature. This study aims to investigate the effect of financial liberalisation on illicit financial outflows in Africa. Furthermore, the study also examines the effect of macroeconomic stability and institutional quality on illicit outflows.

To achieve the objectives, the study uses a dynamic panel system generalised method of moments technique to analyse annual data from the period 1995 to 2015 of 22 African countries.

The results show that financial liberalisation helps to reduce illicit capital outflows. Furthermore, improved institutional quality is associated with lower levels of capital outflows, thus affirming the theoretical expectations that stable political environment boost investor confidence. Overall, the study show that financial liberalisation reduces illicit outflows. However, liberalisation without sound macroeconomic stability and institutional quality may avail opportunities for illicit outflows.

The main limitation of the study was lack of data that spans periods beyond 2015 for most of the variables on financial illicit flows. The available data sources could not test the objectives beyond 2015.

Current literature on the relationship between financial liberalisation and illicit fund outflows are generally conducted in the context implications on economic growth. However, beyond economic growth, financial liberalisation may impact on illicit financial outflows. Furthermore, other institutional and macroeconomic dynamics may influence illicit financial outflow, especially for developing economies in Africa.

User trust in social networking sites (SNS) has become an important issue in SNS discussions. This is because of its impact on knowledge sharing, social commerce, social interaction, among many others. However, information systems researchers have primarily explored the benefits of trust with little attention to its antecedents. In an attempt to address this knowledge gap, this study proposed a model that investigated the factors that promote trust among SNS users. Data was gathered from voluntary respondents using a questionnaire. A PLS-SEM analysis of 912 valid responses suggested that Norm of Reciprocity, Social Interaction Ties and Identification are significant factors that encourage Trust among SNS users. Shared Language was also identified to have impact on Norm of Reciprocity, Social Interaction Ties and Identification. The results of the study provide significant theoretical and practical contributions. They bridge the knowledge gap regarding the formation of Trust on SNS. The model evaluated explains 49.6% of the variance in Trust and thus suitable for analyzing the antecedents of Trust on SNS. Furthermore, with the significance of Identification, Social Interaction Ties and Norm of Reciprocity on Trust, SNS developers are tasked to offer SNS features that proliferate the formation of these factors as well as shared interpretations.

The purpose of this study is to investigate the physical, ultraviolet (UV), colour appearance and colour fastness properties of selected fabrics dyed with natural dyes from Daboya and Ntonso communities of Ghana. The study further highlights the rich cultural heritage of traditional dyeing from these two communities. Craftsmen in West Africa especially Ghana, have sustained the traditional dyeing methods to produce textile products for consumers.

In this study, two sample fabrics were purchased from craftsmen at Ntonso and Daboya communities in Ghana. These fabrics were analysed at the laboratory under standard test methods for their physical, UV, colour appearance and colour fastness properties.

Results showed that all the sample fabrics have good UV shielding performance (ratings above 50+). Daboya sample fabrics (dyed with indigo dyes) produced more colour stains than the sample fabrics from Ntonso (dyed with black “kuntunkuni” dyes). The K/S_sum value or colour yield reduced after washing but that alternatively increased the calculated ultraviolet protection factor.

Findings from this study exposed the unique UV performance of dyed traditional fabrics (using natural dyes) from Ntonso and Daboya communities in Ghana. This inspires and enforces the need for craftsmen to improve their production cycle to produce these fabrics in different sizes which provides the necessary UV shielding abilities for consumers in the wake of climate changes.

This study demonstrated that the natural dyeing process at the two communities produced relatively good UV and colour fastness properties of the sample fabrics. These eco-friendly dyeing practices have survived over time to maintain and promote the concept of sustainability within the textile and fashion industry in Ghana.

The manufacturing industry is a well-known source of interventions adapted to solve problems in the construction industry. The use of Training-Within-Industry (TWI) is one such intervention adopted in the construction industry to solve the construction problem relating to occupational health and safety (OHS). The objectives of TWI are to help the industry to transfer knowledge and skills from management to the employees. Therefore, the purpose of this paper was to investigate whether TWI can reduce OHS problems by promoting “learning by doing” on construction sites.

A case-based-research method was used to investigate the reported OHS problems in the construction industry in South Africa. The data were quantitative and qualitative in nature; the questionnaire survey, semi-structured interview and focus group interview techniques were used to collect data in the study.

The findings provide a better understanding of the human contributions influencing the behaviour of people causing accidents on construction sites. The data show that construction project leaders struggle to promote “learning by doing” because of inappropriate behaviour, lack of communication and inadequate training provided to new workers on construction sites. Also, there is significant scope for TWI deployment in construction because of the inability of supervisors or management to promote “learning by doing” on construction sites.

Based on the research findings, it is discovered that OHS is a serious concern in the construction industry. Therefore, the adoption of learning by doing on a construction site would help to improve OHS outcome.

The study highlights the need to introduce TWI on construction sites to reduce human failure causing accidents. TWI could lead to improving the knowledge- and skills-transfer programmes for construction workers in favour of better safety performance.
