A pricing model for sustainable ICT development in a heterogeneous environment

Sumbwanyambe, Mbuyu 14 January 2014 (has links)
D.Ing. (Engineering Management) / Promotion of ICT usage in developing countries, even under rigorous government initia- tives and policies, is a discouraging undertaking and a very di cult one. One of the many challenges government of developing countries is facing in the promotion of ICT adoption is how to incorporate a subsidy rate discount into a price model as expressed in the following sentiments: Until now, USAASA has used very little of the money in the USAF. It must justify its spending plans each year before it is given access to any of Information on how price a ects the number of users was generated by asking users on how much the spent on internet usage. The sensitivity of users was determined by asking users how many hours they spent on the internet. Analysis of the information gathered showed that there was a substantial amount of money in USAASA and ZICTA co ers which was not utilized. Furthermore users expressed desire to have their prices subsidized. In rural areas internet prices were more expensive, on comparative terms, than those in the urban areas. Analysis of data or results concerning the price and the number of users showed that there was a positive relationship between the number of users and the price of the internet service. The relationship showed that a low price attracted a lot of users, while a high price attracted few users or none at all. The mathematical analysis of the pricing model proved that at a certain subsidy discount rate and price sensitivity, the model was able to reach equilibrium while maximizing the ISP's revenue. In conclusion the price of internet services for the information \have nots" depend on the price sensitivity and the level of subsidy given by the government. the funds". \Universal access of ICT services with particular reference to rural areas is an issue that has been on the agenda of most countries in the whole world today. You are aware that while some countries are currently e ectively extending services to rural areas using various means, others have found this challenging and have ended up with unutilized funds in the banks". Subsidies, though seen as the means of promoting social and economic agendas in developing countries, can create the tragedies associated with public resources usage or something-for-nothing resources. Given a subsidy discount rate or a low price, consumers usually anticipate a net bene t derived from free resources due to subsidy. Anticipation of net a bene t from such resources may generate a damaging rush from consumers to exploit the resource, which may result in the tragedy of the commons. On the contrary, when no subsidy is given, consumers face no di erential between the perceived utility and the price of the resource creating a no social and pecuniary bene t to users, as such very few consumers or users will utilize the resource. The contribution this research develops is as follows: To show the extent of ICT usage patterns in developing countries.To determine why ICT usage in developing countries is low even under rigorous government initiatives and policies. To determine how price a ects the number of users using the internet resource. To incorporate a subsidy discount rate in a price model for unserved or rural areas of developing countries. To proposes a subsidy driven pricing framework that helps both the internet service providers and users to maximize their utilities and prevent the tragedies associated with resource use i.e. the tragedy of the commons and the tragedy of the anti- commons. To apply a non-cooperative game theoretic model to investigate the con ict between ISPs and consumers or consumers in a heterogeneous communities i.e. the infor- mation \haves" and \have-nots". We de ne utility-based decision rules for both providers and users under varying prices and subsidy requirements. We provide a decision model under a non-cooperative, incomplete-information game environment. To investigates the properties of the NE (under di erent optimization rules) and to study whether there exists an optimal solution to the game. The basic hypothesis that this research addresses is: A pricing model, with correct subsidy discount rate allows for better resource usage (preventing the tragedy of the commons and anti-commons) and makes the attainment of the objective of \ICT access for all" more likely. The methodology used for collecting statistical data was a combination of qualitative and quantitative research methods. The purpose of research was to collect data that would later be used to propose a pricing framework for heterogeneous communities. The strategy was to use three important variables in the subsidy driven pricing model to validate the hypothesis i.e. subsidy discount rate, the relationship between price and the number of users and the sensitivity (elasticity of demand) of users towards price. Incorporation of subsidy discount rate into the pricing model was driven by the fact that institutional frameworks such as universal service and access agency of South Africa (USAASA) and the Zambia information and communications tech- nology authority (ZICTA) were sitting with unutilized universal service and access fund (USAF). Additionally, users of internet services in underserviced areas of the two countries advocated for subsidized prices towards internet provision.

The perspectives of technology implementers about informaton communication technology deployment to rural communities in KwaZulu-Natal.

Jere, Ntabeni. January 2011 (has links)
The purpose of this study was to explore the deployment of Information Communication Tech-nology to rural communities of KwaZulu-Natal from the perspective of the State Information Technology Agency (SITA), the technology implementers of government. SITA‘s regional of-fice in KwaZulu-Natal is relatively small, with a total of 52 employees who have a direct and indirect role to play with regards to ICT deployment. A quantitative research methodology was utilised in this study. Data was gathered with the aid of a questionnaire. Fifty-two questionnaires were sent out to the targeted employees of SITA and forty-seven responses were received. The response rate was ninety percent. The results of the survey revealed that sixty percent of respondents felt that rural communities in KwaZulu-Natal were not prepared to participate in e-government. When asked to indicate the importance of Information Communication Technology policy and regulatory frameworks that specifically address technology deployment to rural communities in KwaZulu-Natal, sixty per-cent of respondents acknowledged the importance. Over two thirds of respondents indicated that lack of infrastructure was a hindrance to technology deployment while less than one third did not know if this was a hindrance. The study also revealed that the main motivation for ICT de-ployment was social inclusion and to improve digital inclusiveness. Based on the empirical evidence, the researcher recommends that government take these per-spectives of the technology implementers into consideration when formulating Information Communication Technology policies and legislative frameworks that will be used as a basis for technology deployment to these rural communities. It is also recommended that government do more in terms of training and sensitizing technology implementers and end users, and developing support infrastructure, such as the electrification of rural communities in KwaZulu-Natal, in order to create an enabling environment for new ICT initiative deployment and to enable com-munity members to be adequately prepared to participate in ICT initiatives such as e-governance, which was identified as a priority area. Due to the limitations of this study, particu-larly the fact that it is based on one province, KwaZulu-Natal, it is recommended that further research be carried out into deployment of ICT to rural communities. / Thesis (M.Comm.)-University of KwaZulu-Natal, Pietermaritzburg, 2011.

Factors motivating information technology professionals to become self-employed.

Dwarika, Roopnarain. January 2012 (has links)
The world economy and industry in turn is driven by technology and innovation at a rapid rate. Worldwide, the information technology (IT) industry is volatile in terms of turnover intentions of IT professionals The unemployment level in South Africa is high according to global standards. The option of contracting as an IT consultant or self-employment is a form of an alternate employment arrangement. This arrangement will benefit the unemployed in South Africa if they choose to skill themselves and pursue a career in self-employment in the IT industry. There are internal and external employment factors that affect an IT professional’s employment arrangement. Moore’s (2000) information technology employee turnover model was adapted as a basis for this research. An external factor, entrepreneurship (self-employment) was introduced to Moore’s model. This research also tests Moore’s (2000) model for its internal factors. The following factors, role ambiguity, role conflict, autonomy, perceived workload, fairness of reward, work exhaustion and entrepreneurship were formulated in the hypotheses to determine which of these factors influences self-employment in IT professionals. Information technology professionals based in Durban were the target respondents in the City of Durban. The survey questionnaire was emailed to respondents using Questionpro. The sample data was based on 123 respondents who completed the survey. The data was then validated for internal consistency using Cronbach alpha ratio generated by the SPSS (version 19.0) software tool. The quantitative research design was chosen. Frequency tables and Pearson’s bivariate correlation coefficient statistics was used in the data analysis phase. The research objective was achieved successfully and the following factors were determined, they are role ambiguity, role conflict, autonomy, work exhaustion and entrepreneurship. The IT industry is volatile with IT professionals constantly re-skilling themselves to be on par with changing technology and innovation that make them very competent and competitive as a result, these IT professionals create a market for self-employment. / Thesis (MBA)-University of KwaZulu-Natal, Durban, 2012.

Conceptualising the effectiveness of the black economic empowerment scorecard as a tool for addressing information technology governance challenges

Mohapi, Mateka 07 June 2012 (has links)
M.Tech. / There is currently a lot of research work being done to gain insight into the value proposition for IT governance frameworks and different other variables that have significant bearing on successful implementation of IT governance in South African organizations. There has however been no adequate research conducted on how Black Economic Empowerment (BEE) policy and more specifically the four significant elements of the BEE scorecard (ownership, preferential procurement, skills development and management and control) affect IT governance within South African Enterprises. The study explores BEE policy as a means of redressing past inequalities and then presents BEE challenges that influence IT governance implementation. A broad outline of the research and a conceptual framework that will assist in monitoring the effectiveness of these four elements of the BEE scorecard towards IT governance implementation are presented. The study aims at giving an improved understanding and insights about the strength of the relationship between these two variables (BEE scorecard and IT governance), both of which have a bearing on the success of businesses operating in South Africa as a third variable. Kaplan and Norton„s balanced scorecard is used to measure business success (organization performance). The adopted method of data gathering was quantitative research with extensive use of questionnaires that targeted IT professionals and practitioners closely affiliated with BEE initiatives. The findings show a weak association between BEE and successful IT governance implementation. The results also reveal IT governance maturity has advanced to well-managed level 4.The human capital and diversity in the IT workforce lag behind in progress as a result of inadequate adherence to BEE metrics. There was a strong relationship between organization performance and BEE metrics, and a very weak link between IT governance and organization performance. It is envisaged that the resulting framework arising out of this work will form a foundation for other scholars and practitioners in the IT governance field to expand on gained knowledge, espousing the creation of a compressive IT framework that does not only focus on management tools and frameworks for IT governance efficiency but embraces the social dimensions of IT governance that may inhibit or enable IT governance effectiveness.

A phenomenological study of critical success factors in implementing information governance

Smith, Michael Scott 04 February 2016 (has links)
<p> Information Governance (IG) professionals are overwhelmed by the complexities and ever changing regulations regarding data and information. To compound the issues are the increased volume, velocity, and variations of data from social media to corporate applications. The purpose of this phenomenological study was to determine critical success factors in implementing information governance within an enterprise information management program. The logic for using the qualitative method of research was to capture the lived experiences of the participants regarding the implementation of an information governance program. Phenomenology accentuates the subjective experiences and interpretations of the participants. Interviews were conducted with 20 IG professionals. The participants were interviewed using a semistructured interview providing open ended responses. The interviews were transcribed and six major themes emerged from the study that may provide insight into understanding the critical success factors in implementing information governance: (a) executive support, (b) risk management, (c) change management, (d) communication, (e) technology, and (f) strategy and planning. The study recommends further research from the findings of the study. Executive support must be engaged for the long-term IG program and support the IG professional by providing the necessary resources to manage risk, promote change management, and encourage open communication. Recommendations for IG professionals to consider based on this study include nurturing of executive sponsorship, the need to balance risk management with business value, the necessity of speaking the language of internal customers, building collaborative relationships, and leveraging the learning.</p>

Factors influencing information communication technology (ICT) acceptance and use in small and medium enterprises (SMEs) in Kenya

Nyandoro, Cephus K. 02 March 2016 (has links)
<p> Research demonstrates that there is a gap in focusing understanding factors of information communication technology (ICT) acceptance and use in small and medium enterprises (SMEs). ICT is gaining popularity because it is a force in the economic growth equation. SMEs adopt ICT to promote their business strategy, performance, and growth. This study focused on the factors influencing ICT acceptance and use in SMEs. The research questions were 1) what factors influence SME owners/managers to accept ICT in Kenya? 2) What is the relationship between ICT acceptance and SMEs retail business growth in Kenya? and 3) What is the relationship between ICT usage and SMEs retail business growth in Kenya? The researcher used quantitative research methodology to survey SME owners/managers in Kenya. The researcher hand delivered the survey to 121 potential participants, of which 118 responded. This study evaluated factors of ICT acceptance in SMEs, the relationship between ICT acceptance and SME growth, and the relationship between ICT usage and SME growth. Research findings showed that customer services, cost reduction and business relationships were the most influential factors of ICT acceptance. Computer applications and mobile phones were the most commonly used ICT tools. The study found a strong positive relationship between ICT acceptance and SME growth, and a moderate positive relationship between ICT usage and SME growth. The research results are valuable to stakeholders including potential entrepreneurs, sponsors, government official and financial institutions who make informed decision and formulate policies about ICT investment and effective business strategies for SMEs growth.</p>

University ERP implementation in Germany| Qualitative exploratory case study of administrative staff experiences

Thelen, Anja 15 March 2016 (has links)
<p> Enterprise Resource Planning (ERP) implementations are expensive, time-consuming, and often do not lead to the expected outcome of integrated IT systems. Many German universities are implementing ERP systems as Campus Management Systems (CMS) and a solution to any problem, need, or requirement the organization has. This exploratory case study describes cases of CMS implementations in administrative departments in German universities. Thirteen non-managerial staff members in the registrar offices of two universities shared their experiences about critical factors during and after a CMS implementation. The interview questions focused on (a) implementation experiences, (b) implementation leadership, and (c) impact on daily work processes. The interviews were held, transcribed, and analyzed in German. The inductive analysis of the interviews revealed three main themes: (a) communication, (b) system customization, and (c) team composition and resources. The predominant subject in the theme communication was lack of internal and external communication regarding the CMS project. The overarching system customization theme was the complexity of administrative requirements and continuous and rapid adaptation needs requiring increased CMS team support. The focus of the team composition and resources theme was to employ knowledgeable employees thorough and beyond the end of the project to react to changing requirements. These themes are concurrent with previous research but are unique in that previous research did not focus on CMS in Germany. The themes differ because sub-categories are stakeholder group specific and highlight CMS implementation phase dependencies.</p><p> Keywords: Enterprise resource planning systems, Higher Education, success and risk factors, Germany</p>

A Mobile Phone HIV Medication Adherence Intervention| Care4Today(TM) Mobile Health Manager

Martin, C. Andrew 20 February 2016 (has links)
<p> This paper presents the findings of a qualitative study designed to describe the experience of HIV medication adherence using a mobile phone application. For the purpose of this qualitative study, nine semi-structured focus group discussions were conducted over a three-month period at an AIDS service organization in Central Texas. The data were analyzed following the principles of thematic analysis. During analysis, four themes were identified and relations between these themes were delineated to reflect the experiences of the 23 participants. Improving adherence to antiretroviral therapy is key in reducing the morbidity and mortality of HIV disease; and daily medication adherence may prevent the occurrence of the development of drug resistant mutant strains of HIV (Mbuagbaw et al., 2011). Adherence to ART may be complex secondary to person, behavioral, and treatment factors (Halkitis, Palamar, &amp; Mukjerjee, 2008); and noncompliance to taking daily HIV medications may be considered a community health issue secondary to risk for viral transmission. The mobile phone application, Care4TodayTM Mobile Health Manager, was the intervention tool; and collection of focus group discussion outcomes over a three-month period with baseline versus end-of-study data determined the feasibility and acceptability of this medication adherence intervention. The greater the intention to engage in a behavior, such as daily adherence to HIV medication regimes, the greater is the likelihood of its performance. The findings suggest that when individuals are offered the necessary resources, such as a mobile phone medication reminder application, they may have greater success in performing the behavior.</p>

The changing role of the Chief Information Officer (CIO) : an inquiry into the demands, constraints and choices of the CIO

Louchart, Eddy Sandy January 2012 (has links)
In recent years, the impact of global forces such as the increasing pace of technological innovation and the growing affluence of emerging economies has changed the role of Information Technology (IT). New sourcing models and increasing competitive pressure have had a significant effect on the way technologies are delivered and subsequently the role of the Chief Information Officer (CIO) has gradually been migrating from one of a support role to that of playing a crucial part in the execution of corporate strategies. Whilst previous academic studies appear to be focused on the different competencies of the CIO, there have been few studies concerning how CIOs perceive their role and their future. Drawing on the various concepts from role theory, this PhD thesis constitutes the first known study aimed at presenting the role demands, constraints and the choices as perceived by the CIOs. Using a qualitative approach, 25 semi-structured interviews were conducted with both CIOs and senior IT leaders. Empirical evidence highlights the critical importance of role choices in determining what type of CIO an individual will be. It has also enabled the development of two new CIO role models; the Abeyant CIO and the Transmuted CIO. The Abeyant CIO model has been established to help understand the role enactment of CIOs who have not yet made the transition from a manager to a leader. In this scenario, it is asserted that individuals are the recipient of a role that was formulated by the role set, and that this ultimately determines the level of demands and constraints within the individual’s environment. In contrast, the transmuted CIO scenario emphasises that individuals have been through a process of self-reflection and they have made conscious choices throughout their careers that have resulted in approaching the CIO role differently. It is theorised in the transmuted CIO scenario that individuals are not the mere recipient of role set expectations and that they are actively involved in role making.

Established liked versus disliked brands: brain activity, implicit associations and explicit

Bosshard, Shannon, Bourke, Jesse, Kunaharan, Sajeev, Koller, Monika, Walla, Peter January 2016 (has links) (PDF)
Consumers' attitudes towards established brands were tested using implicit and explicit measures. In particular, late positive potential (LPP) effects were assessed as an implicit physiological measure of motivational significance. The implicit Association Test (IAT) was used as an implicit behavioural measure of valence-related aspects (affective content) of brand attitude. We constructed individualised stimulus lists of liked and disliked brand types from participants' subjective pre-assessment. Participants then re-rated these visually presented brands whilst brain potential changes were recorded via electroencephalography (EEG). First, self-report measures during the test confirmed pre-assessed attitudes underlining consistent explicit rating performance. Second, liked brands elicited significantly more positive going waveforms (LPPs) than disliked brands over right parietal cortical areas starting at about 800 ms post stimulus onset (reaching statistical significance at around 1000 ms) and lasting until the end of the recording epoch (2000 ms). In accordance to the literature this finding is interpreted as reflecting positive affect-related motivational aspects of liked brands. Finally, the IAT revealed that both liked and disliked brands indeed are associated with affect-related valence. The increased levels of motivation associated with liked brands is interpreted as potentially reflecting increased purchasing intention, but this is of course only speculation at this stage.
