Team-related factors influencing intra-team knowledge sharing in knowledge-intensive businesses

In today’s knowledge-driven economy, knowledge is regarded as possibly the most important factor of production next to labour, land and capital. Knowledge is the lifeblood of a business and therefore crucial for its survival in today’s constantly changing and competitive economic environment. In fact, effective knowledge management holds many benefits for an organisation, such as increased productivity and enhanced business performance. Knowledge management is therefore key to ensure business success. In the knowledge management process, knowledge-sharing is typically recognised as the most important activity. Knowledge that is not shared, in particular tacit knowledge residing in the minds of individuals and accrued over time, loses its value. Notably, team knowledge-sharing is of utmost importance in that it enables a team to resolve practical issues more successfully, given that knowledge is shared among team members that hold various kinds of specialised and unique expertise. Organisations increasingly organise their specialised knowledge-intensive work around projects that consist of allocated members who cooperate on a regular basis to accomplish specific goals before a set deadline. However, without knowledge-sharing among team members, the diverse knowledge of various members cannot be optimally utilised to the benefit of the team and the organisation. Although it is well documented that knowledge-sharing among team members, in particular knowledge-intensive teams, may hold various advantages for teams and organisations in terms of their performance and competitive advantage, researchers also acknowledge that individuals are sometimes reluctant to share their knowledge. Moreover, there is a lack of empirical research on the team-related factors influencing intra-team knowledge-sharing, and a subsequent lack of guidance in terms of encouraging intra-team knowledge-sharing behaviour. Notably, the lack of current systematic, integrated research, that pay particular attention to the team-related factors influencing the knowledge-sharing behaviour within a team is problematic. This lack of research calls for further empirical research to better understand the teamrelated factors influencing intra-team knowledge-sharing behaviour in knowledgeintensive teams. As such, the main research objective of this study was to identify and empirically examine selected team-related factors influencing the intra-team knowledge-sharing behaviour of individual members participating in knowledgeintensive teams in knowledge-intensive businesses. Based on an extensive literature review, the following team-related factors influencing knowledge-sharing in a team context were identified and hypothesised to have a relationship with the dependent variable Intra-team knowledge-sharing behaviour. These factors, which also served as the independent variables in this study, are: Team development competition, Team hyper-competition, Team psychological safety, Perceived surface-level diversity, Perceived deep-level diversity, Team identification, Metacognitive cultural intelligence, Cognitive cultural intelligence, Motivational cultural intelligence, Behavioural cultural intelligence, Affective team commitment, Continuance team commitment and Normative team commitment. Following the construction of the proposed hypothesised model, the researcher proceeded to develop a research design that would be suitable to address the research questions. For the purpose of this study, a positivist research philosophy and deductive approach to theory building were adopted, which is in line with the quantitative nature of this study. In addition, a survey research strategy was used and the study was cross-sectional in nature. The measuring instrument, which was in the form of a self-administered online questionnaire, was subjected to a pilot study. Minor adjustments were made to the questionnaire before an electronic link to the final version, accompanied by a cover letter, was e-mailed to 8 496 potential respondents. These potential respondents, who were identified using a convenience sampling technique, were likely to participate in knowledge-intensive teams and be representative of the population. A total of 384 usable responses were received. Following the data collection, the data were analysed to examine the proposed relationships as depicted in the hypothesised model. To address possible multicollinearity concerns associated with different variables that belong to a shared category, such variables were first combined into a single hierarchical variable. Thereafter, a confirmatory factor analysis (CFA) was performed on each factor that confirmed the factor structures by using various goodness-of-fit indices. Subsequent to the CFAs, the validity and reliability of the measuring instrument was assessed. The reliability of the measuring instrument was evaluated using Cronbach’s alpha coefficients, while the assessment of validity involved calculations of the average variance extracted (AVE) estimates and squared correlations between constructs. Based on the results of the reliability and validity assessments, the hypothesised model was revised accordingly. The revised model included Team development competition, Team psychological safety, Cultural intelligence, Team commitment and Perceived deep-level diversity as the independent variables influencing Intra-team knowledge-sharing behaviour. Descriptive statistics and correlation results were presented on the constructs in the revised hypothesised model, while a structural equation modelling (SEM) analysis was the main statistical technique used to test the significance of the relationships between the dependent and the independent variables. The relationships between selected demographic variables and Intra-team knowledge-sharing behaviour were assessed by means of general linear modelling (GLM), a subset of SEM. In light of these analyses, it was concluded that Team psychological safety, Team development competition, Cultural intelligence and Age have a significant influence on Intra-team knowledge-sharing behaviour and could thus be seen as predictors or determinants thereof. Of all the significant relationships identified in this study, Team psychological safety had the strongest effect on Intra-team knowledge-sharing behaviour. One should, however, not lose sight of the impact that competition and cultural intelligence could have on the knowledge-sharing behaviour of individual members participating in knowledge-intensive teams. This study contributes to the body of knowledge-sharing research in general, but also to knowledge-sharing behaviour in a team context in particular. Besides the theoretical contributions, this study makes several practical recommendations to knowledgeintensive businesses on how to manage the team-related factors influencing the Intrateam knowledge-sharing behaviour of individual members participating in knowledgeintensive teams. These recommendations could possibly enhance the competitive advantage of knowledge-intensive businesses.Thesis (PhD) -- Faculty of Business and Economic Sciences, 202

ICT Framework to Support a Patient-Centric approach in Public Healthcare: A Case Study of Malawi

Although Information and Communication Technologies (ICTs) in the healthcare sector are extensively deployed globally, they are not used effectively in developing countries. Many resource poor countries face numerous challenges in implementing the ICT interventions. For instance, many health applications that have been deployed are not user-centric. As a result, such ICT interventions do not benefit many health consumers. The lack of an ICT framework to support patient-centric healthcare services in Malawi renders the e-health and mhealth interventions less sustainable and less cost effective. The aim of the study was therefore to develop an ICT Framework that could support patient-centric healthcare services in the public health sector in Malawi. The comprehensive literature review and semi-structured interviews highlighted many challenges underlying ICT development in Malawi. An ICT framework for patient-centric healthcare services is therefore proposed to ensure that eHealth and mobile health interventions are more sustainable and cost effective. The framework was validated by five experts selected from different areas of expertise including mhealth application developers, ICT policy makers and public health practitioners. Results show that the framework is relevant, useful and applicable within the setting of Malawi. The framework can also be implemented in various countries with similar settings

Characterization of End-users’ Engagement and Interaction Experience with Social Media Technologies

People, particularly digital citizens, gain more technological experiences from their frequent usage of social media technologies. Their experience as end-users occurs before, during, and after their engagement and interaction with the technologies and is popularly described using behaviour-related definitions. However, an end-user\u27s experience with technologies goes beyond the \u27click-and-type definition. This prompts the question, what are the user experience elements that define and characterise end-users\u27 engagement and interaction with social media technologies? . Using a case study-based approach, end-users\u27 engagement and interaction with social media technologies were identified. The study\u27s findings indicated that several user experience elements were characterised by emotions, cognitive, and behavioural dimensions. Combining the characteristics of the dimensions resulted in a more holistic view of the engagement and interaction that end-users have with social media technologies

Challenges, Benefits, and Adoption Dynamics of Mobile Banking at the Base of the Pyramid (BOP) in Africa: A Systematic Review

Increased mobile penetration in Africa offers great potential to accelerate financial inclusion through increased adoption of mobile banking by people at the base of the pyramid (BOP) on the continent. This article provides results from a systematic review of existing research findings on the challenges, benefits and adoption dynamics of mobile banking at the BOP in Africa. The systematic review, which followed PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines, identifies the following key challenges for mobile banking diffusion at the BOP on the continent: poor mobile connectivity; lack of awareness of mobile banking services; illiteracy; poverty; lack of trust due to perceived security risks; legal and regulatory frameworks; and cultural factors. Based on analysis of these challenges, and of the benefits and adoption dynamics also identified, the article provides recommendations for how mobile banking services can be more sustainably implemented for the benefit of people at the BOP in Africa.CA201

Unethical decision-making and behaviour in the life insurance sector of South Africa

The public is regularly shocked by revelations of new business scandals. Nearly every sector of society is tainted by incidents of unethical behaviour. In this regard, the South African financial services industry has attracted a lot of attention, as some of the biggest scandals in recent years have occurred in this industry. With the world economy still experiencing the effects of the global recession, the last thing that institutions in the financial arena must do is engage in unethical behaviour. Immoral behaviour could damage a company's repution and lead to further financial losses. The purpose of this study was thus two-fold: firstly, to investigae the factors that influence unethical decision-making and behaviour in the local life insurance sector, and secondly to evaluate how business ethics are institutionalised at a sample of life insurance companies

ICT as an enabler of Socio Economic Development

Today’s is a world of many divides, one of the most typical being the Digital Divide, which in itself has given birth to or is worsening other economic and social divides. In this world, more suffer and less are able to benefit from technology. This paper aims to promote the importance of and need for inter-disciplinary cooperation for the use and promotion of Information and Communication Technologies (ICT) as a bridge for the Digital Divide within disciplines. Information and communication technologies (ICTs) include any communication device—radio, television, cellular phones, computer and network hardware and software, satellite systems, the services and applications associated with them, such as the Internet, geographic positioning systems (GPS), banking, e-health, e-learning and electronic government services. The paper will touch on tangible examples of inter-disciplinary cooperation and the use of ICT in different community interventions

Individual-related factors influencing knowledge-sharing intention in knowledge-intensive businesses

It has become generally accepted to refer to today‟s global economy as a knowledge-based economy, since knowledge has increasingly become the resource, instead of a resource for wealth creation. The ability of businesses to harness the potential of intangible assets such as knowledge has become far more decisive than their ability to manage physical assets. In the implementation of knowledge management activities, knowledge sharing is recognised as an integral task and key enabler of knowledge management. Although knowledge sharing is regarded as one of the most crucial factors in the effective management of knowledge, in knowledge-intensive businesses in particular, it has also been established that most employees are reluctant to share knowledge. Research further confirms that the factors that promote or discourage knowledge-sharing behaviour in businesses are poorly understood and that knowledge management systems fail as a result of the misunderstanding of individual characteristics that could influence knowledge sharing. Moreover, the focus of knowledge-sharing literature, in terms of the unit of analysis, is rarely at an individual/micro level, although the role of individuals in the knowledge-sharing process is critical as tacit knowledge resides within the individual and knowledge sharing starts with individuals. Given the importance of understanding knowledge sharing of individuals in knowledge-intensive businesses – but noting the lack of existing systematic, integrated research that focuses on individual-related factors influencing knowledge sharing – the purpose of this study was to fill the gap in the current literature. As such, the primary objective of this research was to identify and empirically investigate the individual-related factors influencing the Knowledge-sharing intention of individual employees in knowledge-intensive businesses. The literature review revealed twelve constructs, namely Individuals’ awareness, Intrinsic motivation, Extrinsic motivation, Transactional psychological contract breach, Relational psychological contract breach, Relationship conflict, Task conflict, Extraversion, Neuroticism, Openness to experience, Agreeableness and Conscientiousness that could influence the dependent variable Knowledge-sharing intention in knowledge-intensive businesses. Various moderating relationships between the dependent and independent variables were also proposed, while seven demographic variables (Age, Gender, Language, Highest qualification, Ethnic background, Organisational tenure and Job tenure of the respondent) were identified as potential control variables. Each construct in the hypothesised model of individual-related factors influencing Knowledge-sharing intention was defined and operationalised using items sourced from validated measuring instruments in previous studies. Several self-generated items based on secondary sources were also formulated. A structured questionnaire was made available to respondents identified by means of the convenience sampling technique, and the data collected from 597 usable questionnaires was subjected to various statistical analyses. An exploratory factor analysis (EFA) was conducted which confirmed the unique factors present in the data, and Cronbach-alpha coefficients were calculated to confirm the reliability of the measuring instrument. Structural equation modelling (SEM) was the main statistical procedure used to test the significance of the relationships hypothesised between the various independent and dependent variables. A subset of SEM, namely general linear modelling (GLM) was used to determine the influence of selected demographic variables on Knowledge-sharing intention and to assess various moderating relationships as proposed in the hypothesised model. The main findings of this study were that personality traits are strong predictors of individual employees‟ willingness to share knowledge, and that the maturity of individuals, in terms of realising the significance and value of sharing their knowledge with others, and in recognising the intrinsic benefits of sharing, influence Knowledge-sharing intention. The main limitations of the study were the use of a convenience sampling technique to collect the data, as well as the dependence of self-report by respondents, which could lead to response bias. This study has added to the body of knowledge management research, in particular knowledge-sharing research, by investigating selected individual-related factors influencing the Knowledge-sharing intention of individuals in a particular subset of businesses, namely knowledge-intensive businesses, and focusing on a particular type of knowledge, namely tacit knowledge. From a business‟s perspective, this study offers recommendations and suggestions for managing these individual-related factors in such a way as to increase knowledge sharing among employees, and as a result, the effectiveness and competitive advantage of knowledge-intensive businesses

Selection of air pollution control technologies for power plants, gasification and refining processes

Air quality legislation in South Africa is entering a transformation phase, shifting the concept of atmospheric emission control towards pollution prevention and emission minimisation through a more integrated approach. This transformation, along with public pressure and increased foreign trade, is providing industries with incentives to consider their effect on the environment and to take action where required. To assist South African industries in determining what air pollution control technologies are best suited to power plants, gasification and refining processes in South Africa; an assessment of air pollution control technologies used in other countries was carried out. This assessment concluded that the best available technologies for power plants to control air emissions are electrostatic precipitators, low-NOx burners, selective catalytic reduction systems and wet flue gas desulphurisation (limestone) systems. For gasification processes it was found that the main air pollution contributor is the gas handling and treatment process. Releases from this process are controlled through dust collection, wet scrubbing, conversion of sulphide compounds, sulphur recovery and the incineration of final vent gases before release to the atmosphere. For refining processes the catalytic cracking unit is normally the largest single air emission source and controlling emissions from this unit avoids controlling multiple minor sources. Emissions from this unit are controlled via wet scrubbing, selective catalytic reduction systems and carbon monoxide boilers. An assessment of the financial effects associated with air pollution control at power plants was conducted by completing a cost analysis. This analysis demonstrated that by increasing capital expenditure on control technologies by R 1,7 billion, the external costs associated with producing electricity can be reduced by almost R 3,4 billion. Formulation of external cost factors for South African conditions, and the development of a software database for the information obtained from the different countries, will promote future technology selections.Dissertation (MASTER OF ENGINEERING(Environmental Engineering))--University of Pretoria, 2007.Chemical Engineeringunrestricte
