Efficiency and Usability of E-Learning Systems : Project-Oriented Methodology Guide

The book presents the efforts of the NBU team to put forward an integralmethodology for evaluation of E-Learning systems. It has been created within the WELKOM project (2004-2006), financed by the Leonardo da Vinci EC program. The methodology given here has been applied successfully for deploying and optimizing three different E-Learning systems in three different contexts – a private industrial company (Turbomeca, France), a SAP training company (VBS, Bulgaria), and a university (NBU, Bulgaria)

The development and institutionalisation of an integrated health care waste information system

Includes bibliographical references.Waste management generally in South Africa is poorly defined and practised, and the inadequate management of health care waste (HCW) has been recognised by the South African government as a significant environmental and public health risk. The literature revealed that an integrated health care waste information system (IHCWIS) serves as an important intervention to address the issue of poor health care waste management (HCWM). The overall key research question which this research asked was: "How does an IHCWIS develop and become institutionalised among health care waste generators?" The aim of the research was to gather empirical data to understand how the development and institutionalisation of an IHCWIS contributes to effective HCWM

Development of an Adaptive Environmental Management System for Lejweleputswa District: A Participatory Approach through Fuzzy Cognitive Maps

Published ThesisEnvironmental pollution caused by mines within the district of Lejweleputswa in Free State is a major contributor to health issues and the inability to grow crops within the mining communities. Mining industries continue to develop environmental management systems/plans to mitigate the impact their operations has on the society. Even with these plans, there are still issues of environmental pollution affecting the society. Though there are Information Communication and Technology (ICT) based pollution monitoring solutions, their use is dismal due to lack of appreciation or understanding of how they disseminate information. Furthermore, non-adopting community members are being regarded as inherently conservative or irrational, but these community members argue that the recommendations and technologies brought to them are not always appropriate to their circumstances. There was concern that local people’s knowledge of their environment, farming systems, and their social as well as economic situation had been ignored and underestimated when ICTs solutions are being implemented (Warburton & Martin, 1999). Another challenge is that there is no station to monitor pollution for small communities such as Nyakallong in the district. This result in mining communities depending on their own local knowledge to observe and monitor mining related environmental pollution. However, this local knowledge has never been tested scientifically or analysed to recognize its usability or effectiveness. Mining companies tend to ignore this knowledge from the communities as it is treated like common information with no much scientific value. As a step towards verifying or validating this local knowledge, fuzzy cognitive maps were used to model, analyse and represent this linguistic local knowledge. Although this local knowledge assists in mitigating environmental pollution, incorporating it with scientific knowledge will improve its relevance, trustworthiness and acceptability by majority of community members and policy-makers. Information and Communication Technologies (ICTs) can accelerate this integration; this is the focus of this research. The increased usages of Information Technology being witnessed today makes it the most important factor for the world to depend on for solutions to many of today’s and tomorrow’s problems. These solutions make use of various forms for dissemination purposes, one of the most versatile dissemination device is a mobile phone since majority of the world’s population do own a mobile phone. In this way information is easily accessible by almost everyone that needs it. A novel environmental management solution was designed to work within the mining communities of Lejweleputswa. The research started off by designing a unique integration framework that creates the much-needed link between local knowledge and scientific knowledge. The framework was then converted into an adaptable environmental pollution management system prototype made up of three components; (1) gathering environmental pollution knowledge; (2) environmental monitoring and; (3) environmental dissemination and communication. To achieve sustainability, relevance and acceptability, local knowledge was integrated in each of the three components while mobile phones were used as both input and output devices for the system. In order to facilitate collection and conservation of local knowledge on environmental monitoring, an elaborate android-based mobile application was developed. Wireless sensor-based gas sensor boards were acquired, and deployed as a compliment to conventional monitoring stations, they were used to gather scientific knowledge. To allow for public access to the system’s data, a web portal and an SMS-based component were also implemented. In order to collect local knowledge from community, a case study of Nyakallong community in Lejweleputswa was carried out. On completion of the system prototype, it was evaluated by participants from the community; 90% of respondents gave a score of ‘excellent ‘

Empowering vulnerable people with serious games and gamification

Although many people will associate games with entertainment and leisure, games can also aim more serious purposes, such as training or education. Games with such goals are called serious games. In addition, gamification means that a (serious) task is enhanced with game elements. Examples of serious games and gamification can be seen in many aspects of daily life. Loyalty programs of stores, educational games in schools, fitness wearables and their gamified applications, rehabilitation games, and so on. In this dissertation, the focus is on a specific domain in which serious games and gamification can create societal benefit, namely by using them to empower vulnerable target groups. In the first part of this dissertation, a literature review is performed to understand the domain of serious games and gamification for vulnerable target groups. Based on this review, research gaps can be identified. Moreover, the review resulted in a taxonomy that is used throughout the dissertation to classify different games and applications. In the following parts of the dissertation, projects addressing two different target groups and in total three vulnerabilities are discussed. The first target group is older adults, who are vulnerable in different ways. In this dissertation, safety risks for doorstep scams and health risks through malnutrition are addressed. The first vulnerability is addressed by a serious game using interactive scenarios of doorstep scams. A diet tracking system that was used to support participants in a diet trial addressed the latter vulnerability. The second target group is young adults, which is an age group with a vulnerable mental well-being. The last part of this dissertation aims to study how gamification can be used to enhance self-compassion among young adults via an online 6-weeks training program, to increase their resilience in the face of mental well-being difficulties. Artificial Intelligence (AI) technologies can be used to personalize and adapt the experience of a game to users. Tone of voice analysis was used to influence the progression in scenarios of the serious game about doorstep scams, and it gave players the possibility to assess the assertiveness of their voice. Machine learning algorithms were used to create personalized meal recommendations that can be used to improve the user experience of the diet tracking system for older adults. These algorithms base their recommendations on information about the historical intake of users to suggest meals and to additional items during meal editing. This makes the process of registering a meal less time-consuming. Sentiment analysis is used to adapt responses of the system in an exercise from the self-compassion training program. In addition, a topic detection algorithm was designed to assign one topic from a predefined set of topics to a note by a user of the training program. With this information, users can choose different types of situations to use in the exercises: frequently or rarely discussed topics. Aside from those techniques, knowledge representation is used in all projects, which is important for serious games/gamified applications since they are often based on expert and/or domain knowledge. This dissertation contributes to understanding the domain of serious games and gamification to empower vulnerable groups. The work also contributes to the research on the development of applications within that domain. On top of that, it contributes to understanding how AI techniques can be used to offer (personalized) features that enrich serious games or gamified applications. Finally, for each of the project centered parts, the results that are found in those parts contribute to the research in those specific fields

Investing in employability interventions? : methodological challenges and economic evaluation results

At some point, we will all experience work limitations due to health issues. In some cases, these limitations can lead to a reduction in work efficiency or absenteeism. In the Netherlands, the cost of absenteeism weighs most heavily on employers, who are expected to pay 70% of the absent employee’s salary for a maximum of two years. Various employability interventions have been developed to help minimise costs and facilitate reintegration. Interventions that focus on cooperation are the most cost-effective and therefore the most recommended. These include interventions that focus on the prevention and early detection of work-related health problems by encouraging an active role by company doctors and interventions that focus on employee-employer cooperation with the help of a mediator

IFPOC Symposium:Discovering antecedents and consequences of complex change recipients' reactions to organizational change.

IFPOC symposium: Discovering antecedents and consequences of complex change recipients' reactions to organizational change Chairs: Maria Vakola (Athens University of Economics and Business) & Karen Van Dam (Open University) Discussant: Mel Fugate (American University, Washington, D.C) State of the art Organisations are required to continuously change and develop but there is a high failure rate associated with change implementation success. In the past two decades, change researchers have started to investigate change recipients' reactions to change recognizing the crucial role of these reactions for successful change. This symposium aims at identifying and discussing the complex processes that underlie the relationships among antecedents, reactions and outcomes associated with organizational change. New perspective / contributions This symposium consists of five studies that extend our knowledge in the field by (i) providing an analysis of change recipients' reactions going beyond the dichotomous approaches (acceptance or resistance) (ii) revealing understudied antecedents-reactions and reactions-consequences patterns and relationships (iii) shedding light on the role of contextual factors i.e team climate and individual factors i.e emotion regulation on the adaptation to change. This symposium is based on a combination of both quantitative (i.e diary, survey) and qualitative (i.e interviews) research methodology. Research / practical implications This symposium aims to increase our understanding of the complex processes associated with change recipients' reactions to change. Discovering how these reactions are created and what are their results may reveal important contingencies that can explain how positive organizational outcomes during times of change can be stimulated which is beneficial for both researchers and practitioners

Qigong at Work: Where East Meets West

State of the Art Qigong is part of Traditional Chinese Medicine (TMC) and aims to balance body and mind. The roots of Qigong lie in China, where Confucian and Daoist scholars (500-400 B.C.) noted that one must learn to balance and relax one’s thoughts and emotions to avoid illness (Yang, 1997). In the Western world, Qigong is best known for its slow and coordinated movements. According to TCM, these movements will help regulate one’s ‘qi’, or life energy, through the body to improve the health and harmony of mind and body. During the practice of Qigong, one’s breathing, attention and movement are aligned. As such, Qigong is sometimes considered Mindfulness in movement (although there are many important differences). New perspectives / contributionsQigong has many positive outcomes on health and wellness. In both patient groups and healthy individuals, Qigong has been shown to improve psychological well-being, quality of life, immune function, balance and related risk-factors, and bone density (Jahnke et al., 2010). As such, Qigong offers a validated way to reduce the physical and mental activation that results from a person's work. While recent research has demonstrated how important it is to take short breaks at work, there is still little attention for Qigong exercises as a means to recover at work.Practical Implications In this presentation, we will explain and practice several Qigong exercises. These movements can be used at work (and at home) to recover from (hormonal) activation, ‘empty’ one’s head, and restore the body-mind balance. <br/
