Dahalin, Zulkhairi. "Factors affecting end-user computing sophistication in small business." Thesis, Aston University, 2000. http://publications.aston.ac.uk/10607/.
Full textAbstract:
This thesis describes research on End-User Computing (EUC) in small business in an environment where no Information System (IS) support and expertise are available. The research aims to identify the factors that contribute to EUC Sophistication and understand the extent small firms are capable of developing their own applications. The intention is to assist small firms to adopt EUC, encourage better utilisation of their IT resources and gain the benefits associated with computerisation. The factors examined are derived inductively from previous studies where a model is developed to map these factors with the degree of sophistication associated with IT and EUC. This study attempts to combine the predictive power of quantitative research through surveys with the explanatory power of qualitative research through action-oriented case study. Following critical examination of the literature, a survey of IT Adoption and EUC was conducted. Instruments were then developed to measure EUC and IT Sophistication indexes based on sophistication constructs adapted from previous studies using data from the survey. This is followed by an in-depth action case study involving two small firms to investigate the EUC phenomenon in its real life context. The accumulated findings from these mixed research strategies are used to form the final model of EUC Sophistication in small business. Results of the study suggest both EUC Sophistication and the Presence of EUC in small business are affected by Management Support and Behaviour towards EUC. Additionally EUC Sophistication is also affected by the presence of an EUC Champion. Results are also consistent with respect to the independence between IT Sophistication and EUC Sophistication. The main research contributions include an accumulated knowledge of EUC in small business, the Model of EUC Sophistication, an instrument to measure EUC Sophistication Index for small firms, and a contribution to research methods in IS.

Full textAbstract:
Approved for public release, distribution is unlimitedThe use of End-User computing (EUC) in the Marine Corps has increased dramatically in recent years. As Marine Corps-sponsored programs progressed, large General Services Administration (GSA) contracts were established which made it relatively easy for government agencies to acquire microcomputers. A strongly centralized strategy, successful in the management of the Marine Corps' mainframe systems, was adopted for the EUC program. This thesis concludes that the centralized strategy embraced by the Marine Corps is inappropriate to contend with the problems faced at the end-user level. End-users must be made an active part of the EUC processes for lasting success. More importantly, current inadequacies in support and education must be addressed immediately to ensure effective use of the assets already procured.

Sule, Mary-Jane. "Trusted cloud computing modelling with distributed end-user attestable multilayer security." Thesis, Brunel University, 2016. http://bura.brunel.ac.uk/handle/2438/12893.
Full textAbstract:
As cloud computing continues to gain popularity and its economies of scale continue to improve, stakeholders want to minimise the security risk, protect their data and other resources while maximising the gains of using any cloud resources and its application. It is predicted that by the end of 2017, bulk of spending on any IT infrastructure would be on cloud infrastructure and services as many critical applications – power, medical, finance among others continue to be migrated onto cloud platforms. For these sectors, the security challenges of cloud adoption continue to be of a great concern even with its benefits. The ability to trust and measure security levels of any cloud platform is paramount in the complete adoption and use of cloud computing in many mission critical sectors. In-depth study and analysis of the trustworthiness of various cloud based platforms/systems are often limited by the complex and dynamic nature of cloud and often do not correctly foresee or practically determine the varying trust relationship between and across the cloud layers, components (schedulers), algorithms and applications especially at a large scale. Tradition security and privacy controls continue to be implemented on cloud but due to its fluid and dynamic nature, research work in the area of end-user attestable trust evaluation of the cloud platform is limited. Most of the current simulation tools do not cater for modelling of Trust on scalable multi-layer cloud deployments (including workflow and infrastructure).Even as these tools continue to be implemented none has been used to cater for all the layers of the cloud platform. This research presents a deployment of trusted computing applied in cloud computing suited for mission critical applications. It attempts to simplify the integration of trusted platform module based integrity measurement into cloud infrastructure. Using Eucalyptus cloud software on server-grade hardware, a trusted community cloud platform was deployed on the Brunel Network as presented in Chapter 3. Security is enhanced by the integration of an end-user accessible TPM integrity measurement and verification process; this guarantees trusted ownership and integrity of the uploaded data and provides additional level of trust for the cloud platform. This research further presents a technique which allows data owners to first secure their data offline by inserting colour drops into the data using steganography. The colour drops are used to detect unauthorised modifications, verify data owner in the event the copyright of the data is in dispute and identify the path through which it was tampered with. This process ensures integrity and confidentiality of the resources. This thesis also presents a trust model using fuzzy logic which was simulated using Simulink in Matlab and subsequently evaluated on an experimental platform deployed on the Brunel network. Using this model, end-users can determine the trust values for a cloud platform or service, as well as, classify and compare various cloud platforms. The results obtained suggest that the outputs of this research work can improve end-user confidence when selecting or consuming cloud resources with enhanced data integrity and protection.

Full textAbstract:
Il est primordial, pour un distributeur d’énergie électrique, d’obtenir des estimations précises de la demande en énergie de leurs réseaux. Des outils statistiques tels que des profils de consommation électrique offrent des estimations de qualité acceptable. Ces profils ne sont cependant généralement pas assez précis, car ils ne tiennent pas compte de l’influence de facteurs tels que la présence de chauffage électrique ou le type d’habitation. Il est néanmoins possible d’obtenir des profils précis en utilisant uniquement les historiques de consommations d’énergie des clients, les mesures desdéparts 20kV, et un algorithme génétique de séparation de sources. Un filtrage et un prétraitement des données a permis de proposer à l’algorithme génétique de séparation de sources des données adaptées. La séparation de sources particulièrement bruitées est résolue par un algorithme génétique complètement parallélisé sur une carte GPGPU. Les profils de consommation électrique obtenus correspondent aux attentes initiales, et démontrent une amélioration considérable de la précision des estimations de courbes de charge de départs 20kV et de postes de transformation moyenne tension-basse tensionPrecise estimations of the energy demand of a power network are paramount for electrical distribution companies. Statistical tools such as load profiles offer acceptable estimations. These load profiles are, however, usually not precise enough for network engineering at the local level, as they do not take into account factors such as the presence of electrical heating devices or the type of housing. It is however possible to obtain accurate load profiles with no more than end user energy consumption histories, 20kV feeder load measurements, a blind source separation and a genetic algorithm. Filtering and preliminary treatments performed on the data allowed the blind source separation to work with adequate information. The blind source separation presented in this document is successfully solved by a completely parallel genetic algorithm running on a GPGPU card. The power load profiles obtained match the requirements, and demonstrate a considerable improvement in the forecast of 20kV feeder as well as MV substation load curves

Full textAbstract:
Research emphasises that effective and efficient end-user training is a vital component of the successful utilization of computer technology and that individual differences (e.g., learning styles, cognitive reasoning schemata) may effect the outcomes of end-user training. This study investigates the relationships between end users' Motivational Intent to use computer technology and individual differences. End users' Motivational Intent to use computer technology is significantly different for between-subjects grouped according to their level of anxiety (i.e., positive, neutral, negative). The empirical results indicate that end users' scholastic ability is an important predictor of the incremental change over time to end users' Motivational Intent to use computer technology. End users' learning styles impact the incremental change over time to end users' Motivational Intent to use computer technology. The results suggest that the tailoring of end-user training methods, techniques and materials to accomodate individual differences may be beneficial and worthwhile.x, 99 leaves : ill. ; 28 cm.

Full textAbstract:
The proliferation of personal computers and end- user computing (EUC) in the United States Marine Corps during the last ten years is well documented and now plays an important role in USMC readiness. The control and planning of personal computers and EUC at the regional level is performed by the Information Systems Management Office (ISMO), the equivalent of the private industry's Information Center (IC). Unlike the USMC mainframe and telecommunications environments, the ISMO environment is loosely controlled from the Headquarters Marine Corps level. This fact has resulted in a 'substantial inventory of incompatible equipment and software.' (MCBul 5271, 1987, p. 4-6) This study concludes that the most significant limiting factor facing the Marine Corps' corporate strategy for control of its ISMO's is a lack of standards and specific direction. The requirement for developing a centralized HQMC directed ISMO policy for control of ISMO resources was confirmed. Theses

Full textAbstract:
Software development is no longer a task limited to professionally trained computer programmers. Increasing support for software customization through scripting, the opening of application programmer interfaces on the Web, and a growing need for domain specific application support have all contributed to an increase in end-user programming. Unfortunately, learning to program remains a challenging task, and the majority of end-user programmers lack any formal education in software development. Instead, these users must piece together their understanding of programming through trial and error, examples found online, and help from peers and colleagues.
While current approaches to address the difficulties facing end-user programmers seek to change the nature of the programming task, I argue that these challenges often mirror those faced by all novice programmers. Thus, pedagogical solutions must also be explored. This dissertation work investigates the challenges that end-user programmers face from a computer science education perspective. I have engaged in a cycle of learner-centered design to answer the high-level questions: What do users know; what might they need to know; how are they learning; and how might we help users discover and learn what they need or want to know? In so doing, I uniquely frame end-user programming challenges as issues related to knowledge and understanding about computer science. Rather than building new languages or programming tools, I address these difficulties through new types of instructional materials and opportunities for felicitous engagement with them.
This work is contextualized within a specific domain of non-traditional programmers: graphic and web designers who write scripts as part of their careers. Through an in-depth, learner-centered investigation of this user population, this dissertation makes five specific contributions: (1) A detailed characterization of graphic and web design end-user programmers and their knowledge of fundamental computing concepts. (2) An analysis of the existing information space that graphic and web designers rely on for help. (3) The implementation of a novel case-based learning aid named ScriptABLE that is explicitly designed to leverage existing user practices while conveying conceptual knowledge about programming. (4) Initial confirmatory evidence supporting case-based learning aids for the informal computing education of web and graphic design end-user programmers. (5) An argument in support of the value of normative computing knowledge among informally trained programmers.

Al-gahtani, Said S. "An empirical investigation of the factors contributing to spreadsheets usage and end-user computing satisfaction." Thesis, Loughborough University, 1995. https://dspace.lboro.ac.uk/2134/10340.
Full textAbstract:
The purpose of this research is to develop and test a model of the relationships between several external and various mediating variables and the end-users' satisfaction and usage of spreadsheets. The present research takes several steps toward establishing a valid motivational model of the end-users. Two fairly general, well-established theoretical models (i) 'theory of reasoned action' (TRA) of human behaviour from social psychology and (ii) 'technology acceptance model' (TAM) from management information systems were chosen as paradigms within which to formulate an extended model Several adaptations to these paradigms were introduced in order to make them applicable to the present context building upon and integrating previous research in a curnulative manner. This led to a model which was tested by a nine page questionnaire with 129 entries. Response data was collected from a cross-sectional survey of 333 university students who have been out for one year training in industry across the UK. A careful reliability and validity analysis for the measures used in the survey was conducted. Multiple regression analysis, path analysis, and LISREL modelling were used as different data analysis techniques. The analysis in part gave good support for the initial model considered but also indicated some shortcomings in the two base models.

ABSTRACT: The rapid introduction of microcomputers into organizations throughout the last decade
gave new importance to the analysis of how technology impacts organizations. In
particular, research on usability has sought to become central to the design and selection
of technology for large organizations. However, definitions and methods are not yet
standardized. Data gathered from semi-structured interviews of three MIS managers and
125 end-users in three organizations suggest that differences in emphasis on, and
definition of usability can exist between these two groups. Usability was not a central
concern to managers when evaluating end-user software packages considered for
adoption as the organizational standard, though it appeared to be so for end-users.
Moreover, managers tended to consider and evaluate usability based only on features
contained in the user interface, whereas end-users often cited contextual factors such as
task and environmental considerations. Implications for technology assessment and future
research into organizational impact of I.T. are presented.

Full textAbstract:
Small to Medium Enterprises (SMEs) need to use Information and Communication Technologies (ICT) to enhance their business processes to become competitive in the global economy. When an information system is introduced to an organisation it changes the original business environment thus changing the original requirements. This in turn will change the processes that are supported by the information system. Also when users get familiar with the system they ask for more functionality. This gives rise to a cycle of changes known as co-evolution. In addition, SMEs have budget constraints which make the problem associated with co-evolution worse. One solution to overcome this situation is to empower end-users to develop and maintain the information systems. Within the above context the work presented addresses the following research question: “How to support SME end-users to develop and / or maintain Web applications to support their business processes?” There are two main components to this question: What are the requirements of a suitable end-user development approach for SMEs and how to create the Web applications based on the requirements. The requirements of a suitable end-user development approach can be established by identifying the different types of Web applications required by SMEs, the capabilities of end-users in relation to developing and / or maintaining Web applications and how they conceptualise the Web applications. The literature review is conducted to discover different types of Web applications required by SMEs and to identify a suitable end-user development approach and tools that can support the development of these various types of Web applications. According to the literature survey, the main types of Web applications required by SMEs can be categorised as information centric Web applications (Simple Web sites which focus on effective presentation of unstructured information), data intensive Web applications (the focus is on efficient presentation and management of structured data such as product catalogue) and workflow intensive Web applications (The focus is on efficient automation of business processes such as an order processing system). The literature on end-user development shows that the existing end-user development approaches are focused on specific types of Web applications. The frameworks and tools in the Web development discipline mainly target experienced Web developers. Therefore a gap is identified as “there are limited end-user development approaches for developments of different types of Web applications which are required by SMEs to IT enable their businesses’”. The capabilities of SMEs in relation to Web application development were identified based on a study conducted with a group of SMEs. This study first surveyed the SMEs experience and knowledge in relation to Web application development and their attitude towards end-user development. Then their capabilities relating to Web application development were studied in a hands-on session to develop a Web site. The second study is conducted with administrative staff members involved in development of a Web application. This study helps to establish the requirements of a suitable end-user development approach from the point of view of the end-user developers. This study on end-user development observed the different activities carried out by end-users. Then the end-user was interviewed to identify the issues and benefits of end-user development in the project. Following that, a set of requirements for the end-user development approach was derived based on the findings from these two studies and the related literature: 1) A need to support different types of Web applications required by SMEs; 2) A need to support the specification of Web applications at the conceptual level; 3) A need for a common data repository to store the data used in
different applications within the organisation; 4) Providing a common login to all applications within the organisation; 5) Striping a balance between Do it Yourself (DIY) and a professional developer that allows end-users to do the activities they are capable of while getting help from a professional developer to do the difficult tasks. The conceptual aspects of different types of Web applications (information centric, data intensive and process intensive) were identified based on a literature survey of existing conceptual modelling approaches. This set of aspects was refined by modelling selected Web applications for each type of Web application. The aspects needed to specify different types of Web applications are: presentation, data, task, workflow, access control, navigation, and personalisation. Then the usage of these aspects in a set of end-user specifications was analysed. This study reveals that end-users only focus on some of these aspects such as data and process to specify the applications. Therefore, another requirement for the development approach was identified – a need to support development of Web applications with minimum aspects. A meta-design paradigm based on the meta-model of Web applications is proposed to support the identified requirements. A meta-model of Web applications is developed based on the patterns of different types of Web applications. A component based Web application development framework called CBEADS (Component based eApplication Development and Deployment Shell) was extended to support the meta-model based development approach. Web applications can be created by populating the values for the attributes of the meta-model which are related to the attributes of different aspects of the Web applications at the conceptual level. The meta-model is organised into three levels: shell level, application level, and function level. Aspects common to many web applications are modelled at the shell level. The data model and user model are stored and managed at the shell level. This supports the requirements of common data repository and the common login to all applications. The aspects common to a web application are modelled at the application level. The function specific aspects required to implement the functionality of the Web application are modelled at the function level. The metamodel has two properties called overriding and inheritance. Inheritance property allows developing Web applications with minimum aspects. The activities required to develop the Web applications in a framework supporting the meta-model are grouped into three levels based on the complexity of these tasks named routine level, logical level and programming level.These different levels together with the overriding property help to balance between DIY and a professional developer. The meta-design paradigm is practically evaluated with a group of users including SMEs and students. The studies establish strategies for the success of the meta-design paradigm such as characteristics of individuals, facilitation and infrastructure. The original contributions of this thesis enhance the field of end-user development by providing a new end-user development approach that can be used by business end-users to develop web applications. More importantly the major contributions of this research provide a practical approach that can be used particularly by SME end-users with little or no previous experience in web application development. Significant research contributions are made in the following four areas: 1) Establishing requirements for an end-user development approach suitable for business users. 2) Identifying a set of aspects required to model different types of Web applications at the conceptual level. 3) Developing a meta-design paradigm
based on the meta-model of different types of Web applications 4) Developing the strategies for successful use of the meta-design paradigm.

Full textAbstract:
This thesis is concerned with temporal factors from the perspective of the interactive designer/interface designer and usability as a construct for guiding design activity. The research reported herein examines the many factors which emerge when considering the name of interaction at the user interface. Temporal
Aspects of Usability (TAU) is presented as a multivariate construct. It is neither a
property that exists 'in the head alone' not is it an aspect of the system but rather
an emergent property arising from task based interactions.
From a theoretical perspective, it is argued that the inclusion of temporal considerations to the task model more fully specifies 'Usability' as a design construct. A model of TAU is evolved and validated utilizing situated interviews with designers. This resulted in an Enhanced model of TAU. A method for developing temporally informed task models, KAT-LITTER (Leveraging Interactions Through Effective Responses), provides temporal design heuristics as the confluence of, KAT (Knowledge Analysis of Task) a task analysis method, and the enhanced TAU model. As a method, KAT-LITTER is device independent, data centered, domain specific and necessarily independent of existing implementations. A process evaluation of KAT-LITTER showed that it influenced the design process in two significant ways: firstly, designers using KAT-LITTER spent more time reasoning about temporal issues than designers using KAT alone, and secondly these same designers considered a broader spectrum of temporal issues.
The development of TAU, its accompanying method, KAT-LITTER, complete with a notational system for analysis represent a significant step forward.

Full textAbstract:
Effective resource management requires tools and decision aides to help determine users' needs and appropriate assignment. The goal of this research was to design, implement, and test technological tools that, even in a dynamic environment, effectively support the matching of users and resources. The context of the investigation is the Information Center, the structure used to manage and control the computing resources demanded by end users. The major contributions of the research lie in two areas: (1) the development and use of a knowledge acquisition called Resource Attribute Charts (RAC), which allow for the structured definition of the resources managed by the IC, and (2) the design, implementation, validation, and verification of the transportability of Information Center Expert, a system that supports the activities of the IC personnel. Prototyping, the system development methodology commonly used in software engineering, was used to design the general architecture of the knowledge acquisition tools, the knowledge maintenance tool, and the expert system itself. The knowledge acquisition tools, RAC, were used to build the knowledge base of ICE (Information Center Expert). ICE was installed at two corporate sites, its software recommendations were validated, and its transportability from one location to another was verified experimentally. The viability of a rule-based consultation system as a mechanism for bringing together knowledge about users, problems, and resources for the purpose of effective resource management was demonstrated.

This dissertation introduces, implements, and evaluates the novel concept of
"Service Paths", which are system-level abstractions that capture and describe
the dynamic dependencies between the different components of a distributed
enterprise application. Service paths are dynamic because they capture the
natural interactions between application services dynamically composed to offer
some desired end user functionality. Service paths are distributed because such
sets of services run on networked machines in distributed enterprise data
centers. Service paths cross multiple levels of abstraction because they link
end user application components like web browsers with system services like
http providing communications with embedded services like hardware-supported
data encryption. Service paths are system-level abstractions that are created
without end user, application, or middleware input, but despite these facts,
they are able to capture application-relevant performance metrics, including
end-to-end latencies for client requests and the contributions to these
latencies from application-level processes and from software/hardware resources
like protocol stacks or network devices.
Beyond conceiving of service paths and demonstrating their utility, this thesis
makes three concrete technical contributions. First, we propose a set of signal
analysis techniques called ``E2Eprof' that identify the service paths taken
by different request classes across a distributed IT infrastructure and
the time spent in each such path. It uses a novel algorithm called ``pathmap'
that computes the correlation between the message arrival and departure
timestamps at each participating node and detect dependencies among them. A
second contribution is a system-level monitoring toolkit called ``SysProf',
which captures monitoring information at different levels of granularity,
ranging from tracking the system-level activities triggered by a single system
call, to capturing the client-server interactions associated with a service
paths, to characterizing the server resources consumed by sets of clients or
client behaviors.
The third contribution of the thesis is a publish-subscribe based monitoring
data delivery framework called ``QMON'. QMON offers high levels of
predictability for service delivery and supports utility-aware monitoring
while also able to differentiate between different levels of service
for monitoring, corresponding to the different classes of SLAs maintained for
applications.

Full textAbstract:
Despite the persistent change and growth that characterizes the Internet,
the Transmission Control Protocol (TCP) still dominates at
the transport layer, carrying more than 90\% of the global traffic.
Despite its astonishing success, it has been observed that TCP
can cause poor end-to-end performance, especially for large transfers
and in network paths with high bandwidth-delay product.
In this thesis, we focus on mechanisms that can
address key problems in TCP performance, without
any modification in the protocol itself.
This evolutionary approach is important in practice, as the deployment
of clean-slate transport protocols in the Internet has been proved
to be extremely difficult.
Specifically, we identify a number of TCP-related problems
that can cause poor end-to-end performance.
These problems include poorly dimensioned socket buffer
sizes at the end-hosts, suboptimal buffer sizing at routers and switches,
and congestion unresponsive TCP traffic aggregates.
We propose solutions that can address these issues,
without any modification to TCP. In network paths with significant available bandwidth, increasing the TCP window till observing loss can result in much lower throughput than the path's available bandwidth. We show that changes in TCP are {em not required} to utilize all the available bandwidth, and propose the application-layer SOcket Buffer Auto-Sizing (SOBAS) mechanism to achieve this goal. SOBAS relies on run-time estimation of the round trip time (RTT) and receive rate, and limits its socket buffer size when the receive rate approaches the path's available bandwidth. In a congested network, SOBAS does not limit its socket buffer size. Our experiment results show that SOBAS improves TCP throughput in uncongested network without hurting TCP performance in congested networks.
Improper router buffer sizing can also result in poor TCP throughput. Previous research in router buffer sizing focused on network performance metrics such as link utilization or loss rate. Instead, we focus on the impact of buffer sizing on end-to-end TCP performance. We find that the router buffer size that optimizes TCP throughput is largely determined by the link's output to input capacity ratio. If that ratio is larger than one, the loss rate drops exponentially with the buffer size and the optimal buffer size is close to zero. Otherwise, if the output to input capacity ratio is lower than one, the loss rate follows a power-law reduction with the buffer size and significant buffering is needed. The amount of buffering required in this case depends on whether most flows end in the slow-start phase or in the congestion avoidance phase.
TCP throughput also depends on whether the cross-traffic reduces its send rate upon congestion. We define this cross-traffic property as {em congestion responsiveness}. Since the majority of Internet traffic uses TCP, which reduces its send rate upon congestion, an aggregate of many TCP flows is believed to be congestion responsive. Here, we show that the congestion responsiveness of aggregate traffic also depends on the flow arrival process. If the flow arrival process follows an open-loop model, then even if the traffic consists exclusively of TCP transfers, the aggregate traffic can still be unresponsive to congestion. TCP flows that arrive in the network in a closed-loop manner are always congestion responsive, on the other hand. We also propose a scheme to estimate the fraction of traffic that follows the closed-loop model in a given link, and give practical guidelines to increase that fraction with simple application-layer modifications.

NETI@home is an open-source software package that collects network performance statistics from end-systems. It has been written for and tested on the Windows, Solaris, and Linux operating systems, with testing for other operating systems to be completed soon. NETI@home is designed to run on end-user machines and collect various statistics about Internet performance. These statistics are then sent to a server at the Georgia Institute of Technology, where they are collected and made publicly available. This tool gives researchers much needed data on the end-to-end performance of the Internet, as measured by end-users. NETI@homes basic approach is to sniff packets sent from and received by the host and infer performance metrics based on these observed packets. NETI@home users are able to select a privacy level that determines what types of data are gathered, and what is not reported. NETI@home is designed to be an unobtrusive software system that runs quietly in the background with little or no intervention by the user, and using few resources.

Full textAbstract:
Effective and efficient training is a key factor in determining the success of end user computing (EUC) in organisations. This study examines the influences of two application interfaces, namely icons and menus, on training outcomes. The training outcomes are measured in terms of effectiveness, efficiency and perceived ease of use. Effectiveness includes the keystrokes used to accomplish tasks, the accuracy of correct keystrokes, backtracks and errors committed. Efficiency includes the time taken to accomplish the given tasks. Perceived ease of use rates the ease of the training environment including training materials, operating system, application software and associated resources provided to users. In order to facilitate measurement, users were asked to nominate one of two approaches to training, instruction training and exploration training that focussed on two categories of users, basic and advanced. User category was determined based on two questionnaires that tested participants' level of knowledge and experience. Learning style preference was also included in the study. For example, to overcome the criticisms of prior studies, this study allowed users to nominate their preferred interfaces and training approaches soon after the training and prior to the experiment. To measure training outcomes, an experiment was conducted with 159 users. Training materials were produced and five questionnaires developed to meet the requirements of the training design. All the materials were peer reviewed and pilot tested in order to eliminate any subjective bias. All questionnaires were tested for statistical validity to ensure the applicability of instruments. Further, for measurement purposes, all keystrokes and time information such as start time and end time of tasks were extracted using automated tools. Prior to data analysis, any 'outliers' were eliminated to ensure that the data were of good quality. This study found that icon interfaces were effective for end user training for trivial tasks. This study also found that menu interfaces were easy to use in the given training environment. In terms of training approaches, exploration training was found to be effective. The user categorisation alone did not have any significant influence on training outcomes in this study. However, the combination of basic users and instruction training approach was found to be efficient and the combination of basic users and exploration training approach was found to be effective. This study also found out that learning style preference was significant in terms of effectiveness but not efficiency. The results of the study indicates that interfaces play a significant role in determining training outcomes and hence the need for training designers to treat application interfaces differently when addressing training accuracy and time constraints. Similarly, this study supports previous studies in that learning style preferences influence training outcomes. Therefore, training designers should consider users' learning style preferences in order to provide effective training. While categories of user did not show any significant influence on the outcomes of this study, the interaction between training approaches and categories of users was significant indicating that different categories of users respond to different training approaches. Therefore, training designers should consider the possibility of treating differently those with and without experience in EUC applications. For example, one possible approach to training design would be to hold separate training sessions. In summary, this study has found that interfaces, learning styles and the combination of training approaches and categories of users have varying significant impact on training outcomes. Thus the results reported in this study should help training designers to design training programs that would be effective, efficient and easy to use.

End User Computing is becoming an increasingly important activity in small firms. This
thesis reports results of an empirical investigation of the factors influencing End User
Computing Success in small businesses. The study proposed a conceptual model which
was based on the Technology Acceptance Model (TAM) theory. Another important
contribution of this study was that it extended previous research by testing a subset of the
TAM in a new context, i.e. small firms. The development and testing of the research model
involved: (1) a pilot case study, (2) a cross-case analysis of eight firms, and (3) a national
survey of 596 computer users. Partial Least Squares was the data analysis technique used
to analyse the survey data. The results of the study indicated that management support,
external support, perceived ease of use, and perceived usefulness had direct positive effects
on EUC success in small firms. Smaller but significant effects were also found for internal
support, internal training, and external training on EVC success. Overall, the results of
the study provided strong support for the TAM theory in a small firm context. Suggestions
for future research and implications for small firm managers, external sources of assistance,
and educational institutions were discussed.

Full textAbstract:
Basic Laboratory Information System (BLIS) is a joint initiative of C4G @ Georgia Tech, the Centers for Disease Control and Prevention (CDC) and Ministries of Health in several countries in Africa. The vast majority of health laboratories in Africa, engaged in routinely testing samples drawn from patients (for HIV, malaria etc.), have been using non-standardized paper logs and manual entries for keeping track of patients, test samples and results. Besides the obvious burden of tedious record-keeping, these methods increase the chances of errors due to transcription and mismatches, making it difficult to track patient history or view critical population-wide data. In 2008, PEPFAR (the United States President's Emergency Plan for AIDS Relief) together with the CDC was reauthorized with a $48 billion budget over five years to combat HIV/AIDS, tuberculosis, and malaria. The focus of PEPFAR has shifted from rapid scale-up to the quality and reliability of the clinical health programs and having an effective laboratory management system is one of its goals.
C4G BLIS is a robust, customizable and easy-to-use system that keeps track of patients, samples, results, lab workflow and reports. It is meant to be an effective and sustainable enhancement to manual logs and paper-based approaches. The system is designed to work in resource-constrained laboratories with limited IT equipment and across sites with good, intermittent or no internet availability. With varied practices, workflow and terminology being followed across laboratories in various African countries, the system has been developed to enable each laboratory or country to customize and configure the system in a way that suits them best. We describe various aspects of BLIS including its flexible database schema design, configurable reports and language settings, end-user customizability and development model for rapid incorporation of user feedback. Through BLIS, we aim to demonstrate a sustainable ICT solution brought about by the early and constant involvement of the target laboratory staff and technicians, identifying their short- and long-term needs, and ensuring that the system can match these needs. We will present preliminary evaluation results from laboratories in Cameroon, Ghana, Tanzania and Uganda.

The use of computers has become part of every day life. The high prevalence of computer use may lead employers to assume university graduates will have good computing skills. Such assumptions may be the reason that employers use broad terms to advertise the computing tasks required for graduate-level positions. This thesis investigates how well the expectations of employers match the perceptions of near-graduates about their computer skills. Four graduate-level positions were identified from advertisements placed in order to recruit graduates. The employers who placed these advertisements were surveyed by interview and questionnaire. Twenty-one students about to graduate from a university commerce programme were also interviewed and surveyed. It was found that the wording of the advertisements did not satisfactorily portray the requirements and intentions of the employers. It was also found that skills the near-graduates perceived they possessed frequently did not meet the expectations of employers. Results also show that the near-graduates did not fully understand which computing skills would be expected in the workplace. This study highlights implications for three groups: employers, graduates and educators.

Full textAbstract:
With current state-of-the-art approaches, development of a single mobile manipulation capability can be a labor-intensive process that presents an impediment to the creation of general purpose household robots. At the same time, we expect that involving a larger community of non-roboticists can accelerate the creation of new novel behaviors. We introduce the use of a software authoring environment called ROS Commander (ROSCo) allowing end-users to create, refine, and reuse robot behaviors with complexity similar to those currently created by roboticists. Akin to Photoshop, which provides end-users with interfaces for advanced computer vision algorithms, our environment provides interfaces to mobile manipulation algorithmic building blocks that can be combined and configured to suit the demands of new tasks and their variations.
As our system can be more demanding of users than alternatives such as using kinesthetic guidance or learning from demonstration, we performed a user study with 11 able-bodied participants and one person with quadriplegia to determine whether computer literate non-roboticists will be able to learn to use our tool. In our study, all participants were able to successfully construct functional behaviors after being trained. Furthermore, participants were able to produce behaviors that demonstrated a variety of creative manipulation strategies, showing the power of enabling end-users to author robot behaviors.
Additionally, we introduce how using autonomous robot learning, where the robot captures its own training data, can complement human authoring of behaviors by freeing users from the repetitive task of capturing data for learning. By taking advantage of the robot's embodiment, our method creates classifiers that predict using visual appearances 3D locations on home mechanisms where user constructed behaviors will succeed. With active learning, we show that such classifiers can be learned using a small number of examples. We also show that this learning system works with behaviors constructed by non-roboticists in our user study. As far as we know, this is the first instance of perception learning with behaviors not hand-crafted by roboticists.

This study investigated the implications that the scheduling of a block module for a
computer competency course over two weeks, has had on the curriculum. The block
module was presented at the start of the first semester, 2001 at the Vaal Triangle
Technikon. The objectives were to:
develop a flexible, outcomes-based curriculum in which the learners had to
demonstrate capability and employability by integrating computer competencies
in other modules;
design and implement an effective learning and teaching strategy in order to
ensure that learners will achieve the learning outcomes within two weeks; and to . implement continuous, integrative assessment methods in order to foster the
learning of hands-on skills that can be integrated in the learners' academic
programmes.
The researcher followed an action research approach, in order to assess the
improvement of current educational practices. A target group of first-year learners
was divided into a block module-group and a semester-group. The researcher made
use of data triangulation, by collecting qualitative and quantitative data comprising
structured interviews and open-ended and structured questionnaires completed at
different stages of the project.
This research report comprises three articles. The first article reports on the high
success rate of the block module-group and reveal that these learners could retain.
and utilise the computer competencies that they had to utilise for completing
assignments, to a larger degree than the semester-group.
The second article reports that experiential learning, as an outcomes-based strategy,
fosters learning in accelerated learning contexts.
The third article concludes that the continuous integrative approach to assessment
fosters w-operation, feedback through self-assessment and the ability of learners to
apply computer competencies in new situations.
It is recommended that lecturers in all the associated departments should
collaboratively assign and assess tasks in progressive advanced modules. It
concludes that, in order to utilise resources optimally when scheduling block
modules, ail associated departments would have to be fully modularised.Thesis (M.Ed.)--Potchefstroom University for Christian Higher Education, 2003.

Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorUbiquitous computing foresees the support to human activities in the most possible integrated environment known by the professional. On this perspective, a major area of its application is the Health System as the health of the future provides the use of ubiquitous computing as a way to automate and optimize the clinical activities. Addressing the problem of rejection of computer systems in health due to the remoteness of the way clinicians perform their tasks, the project "ClinicSpace" proposes a prototype of a tool that enables clinicians to customize and better manage their daily tasks. One of the big challenges is how to model human activities in computer systems, respecting the way that each individual performs them. This way, the contribution of this work is to propose a modeling of the main tasks performed in the clinical hospital settings by clinical professionals with the way that each individual performs the work. Once created the task, the medical professionals can reuse them for the definition and creation of other tasks they may judge necessary. An architecture manages the tasks in the most automatic way possible to undermine the control that the owner must maintain to the environment. Thus, it is expected to reduce the degree of rejection found in computerized systems of hospitals and clinics. The interface developed uses mechanisms provided by the End-user programming to facilitate the use of the clinical professional and Task-driven Computing. Case studies were simulated to demonstrate the feasibility of the proposal. Field tests may only be made after the release of the prototype of the architecture of the management and execution of tasks; however, this work is outside the scope of this dissertation.
A Computação Ubíqua prevê o suporte às atividades humanas da forma mais integrada possível ao ambiente conhecido pelo profissional. Nessa perspectiva, uma das grandes áreas de aplicação é a Saúde, já que o Sistema de Saúde do futuro prevê o uso da Computação Ubíqua como forma de otimizar e automatizar as atividades clínicas. Focando o problema de rejeição dos sistemas computacionais na Saúde devido ao distanciamento destes da forma como os clínicos executam suas tarefas, o projeto ClinicSpace propõe a prototipação de uma ferramenta que permita aos clínicos a personalização e gerenciamento de suas tarefas diárias. Um dos grandes desafios enfrentados é como modelar atividades humanas em sistemas computacionais, respeitando a forma individualizada com que cada pessoa as realiza. Nesse sentido, a contribuição desse trabalho é a proposta de uma ferramenta-piloto que permite ao profissional programar e compor suas tarefas, a partir de uma modelagem das principais tarefas clínicas executadas nos ambientes hospitalares por profissionais clínicos, respeitando a forma individual que cada profissional as realiza. Uma vez criadas as tarefas, os profissionais clínicos podem reutilizá-las para a definição e reuso na criação de outras tarefas que julgarem necessário. Uma arquitetura gerencia a execução das tarefas da forma mais automática possível para não comprometer o controle que o profissional deve manter sobre o ambiente. Assim, espera-se reduzir o grau de rejeição encontrado nos sistemas informatizados dos hospitais e clínicas. A interface de programação de tarefas pelo profissional desenvolvida utiliza mecanismos providos pela Programação Orientada ao Usuário-Final com o objetivo de facilitar a utilização do sistema pelo profissional clínico e pela Computação Orientada a Atividades. Estudos de casos foram simulados para demonstrar a viabilidade da proposta. Testes de campo somente poderão ser realizados após a disponibilização do protótipo da arquitetura de gerenciamento e execução das tarefas, porém, esse trabalho está fora do escopo dessa dissertação.

Traditional development methodology of information systems is either phrase-oriented or developer-oriented. In such case, the final system usually is not what users want. Besides this, there is no good design tool for users to easily express their needs, then to implement a runnable system. In this thesis we develop an end-user computing(EUC) model, and tool as well. The EUC model adopts both advantages of object-oriented methodology (OOM) and structured methodology(SM). Users can choose either top-down or bottom-up approach when designing a system. Extended Data Flow Diagram(EDFD) and Finite State Machine(FSM) which together form an executable requirement language are used to describe customer's needs. In such situation, written requirements become runnable immediately. Also included in this paper are detail descriptions of the EUC tool's implementation.

M.Ed.Computers are an integral part of life, and have become integral to everyday functions of work, travel, health, entertainment and study. It is crucial that this technology be utilised to maximum effect. In schools, learners are increasingly required to enhance their computer skills, and at tertiary level students explore ways they can be used to develop and enhance capacity, functions and responsibilities. This study examines ways in which computer technology can be used to teach, so as to benefit all role-players in the learning process, including lecturers, students, the learning fraternity and industry, contributing to a more competent and capacitated workforce. In particular, it looks at an electronic assessment tool implemented by the University of Johannesburg (UJ), intended to enhance and upgrade learning in courses where computers are used. However, with the initial use of system, certain shortcomings were identified which affected its performance. As computer-related testing was considered important in contributing to assessment, it was critical to identify any problems that were inhibiting its optimal performance. To this end, the researcher studied the subdepartment End-User Computing (EUC), located within the department of Business Information Technology (BIT) at UJ. A qualitative phase consisted of two identified focus groups made up of specific individuals from BIT, comprising lecturers engaged in the daily use and activation of the electronic assessment system and supported by information system technical support personnel. A second phase, quantitative in nature, used responses to structured questionnaires delivered to students who had used the assessment tool. The University’s Statcon unit analysed results, and identified problems. Lecturers pointed to the language used in questions and system challenges to teaching and learning, while students highlighted a need for preparing them for the process, particularly calling for a tutorial with class presentation prior to assessment.

The recently advancement of information technology has stimulated the rapiddevelopment of End-User Computing (EUC) applications. This study examines the factors affecting the EUC performance. We addressed the EUC performance by looking into 5 different dimensions:organizational characteristics, managerial strategies, characteristics of information systems, EUC management unit and characteristics of end user.The EUC performance is measured in terms of EUC satisfaction, work efficiency &effectiveness and user autonomy. We also examine the profiles of EUC applicationin Taiwan. The results of a mail survey indicate that1) In general, MIS managers and end users both have positive attitude toward EUC, but most companies have yet developed EUC plan. Moreover, only 15.9% companies had an official organization unit for EUC support (usually called Information Centers).2) Top manager''s supports have significant impact on the EUC performance. EUC budget also positively correlated with the EUC satisfaction.3) Progressive strategies result in significantly better EUC performance than conservative strategies do.4) Information Center has significant impact on EUC performance. The more EUC supports ICs offered, the better EUC performance the companies had.5) Users have a better EUC satisfaction in using PC applications than using mainframe applications. Window based applications result in better user autonomy than DOS based applications.6) Training, computer competence, computer attitude, and anxiety all positively correlated with EUC performance. A regression analysis is also conducted to measure the relative weights of factors in explaining the EUC performance. The results show that top manager''s support, information center, computer attitude and daily work hours have significant impact on this regard.

This paper proposed a revised technology acceptance model for measuring end user computing (EUC) acceptance. An empirical study was conducted to collect data and the revised model was evaluated by structural equation modeling, and then confirmatory factor analysis was applied to test if the empirical data confirmed to the presumed model. The results demonstrated that the model explained 56% of the variance. The finding contributes to an expanded understanding of the factors that promote the EUC acceptance.
