The rapid growth in the use of wireless communication and portable devices in recent years has created a great potential for a variety of mobile work technology support. However, we still lack the theories to explore the nature of mobile work, examine the needs for mobile work support, and identify the appropriate mobile technologies for various kinds of mobile work. This study is an attempt to meet the challenge. A mobile task model is proposed in this study which includes four dimensions: task complexity, task interdependence, time criticality, and location sensitivity. New instruments are developed to measure the constructs of time criticality and location sensitivity. Six typical mobile work support functions are examined: mobile communication, mobile information searching, mobile transaction processing, location related service, mobile job dispatching and mobile office. In light of contingency theory and attitude/behavioral theory, a research model is proposed to identify the ideal fit between task characteristics and typical mobile work support functions. Based on empirical data from real mobile workers, the nature of mobile work and the differences in mobile work between mobile knowledge workers and field workers are analysed. New instruments for the time and location related constructs are validated through the empirical data. The differences in perceived usefulness of the typical mobile work support functions between mobile knowledge workers and field workers are presented, as well as those of the current usage and intention to use. Finally, the ideal fit is identified on the basis of the empirical data. This study contributes both to theory and practice. The establishment of a mobile task model, including the development of new instruments for time and location constructs, provides a foundation for future mobile business research. The identification of the ideal fit between task characteristics and mobile technology functions, based on contingency theory and attitude/behavioral theory, extends and enriches mobile business research. The results of the study can provide guidance and recommendations on how to strategically plan and implement suitable mobile applications, and to identify opportunities for the development of appropriate technological solutions for mobile work support. / Thesis / Doctor of Philosophy (PhD)

This thesis progressively evolves and presents a practical 'theory' for mobile work – mobile trajectory – through three case studies conducted using fieldwork. The three cases presented here examine tram travellers finding their way around a city centre (Case A), health care workers looking after people with mental illness in a residential setting (Case B) and mobile clinicians caring for young people with mental illness in a community setting (Case C). My concern is to develop a 'theory' for mobile work that is both practical and theoretical,; at once supporting the practical action of completing field and analytic work while abstracting away from the ordinary affairs of society. The contribution of this ‘theory’ is to synthesise ideas from the domain of studies of ICTs mobile work to support description, rhetoric, inference and application for mobile work. This 'theory' has particular COMPONENTS, FEATURES, PROPERTIES, CONCERNS and ASSOCIATED NOTIONS. / A mobile trajectory has a CORE TRAJECTORY that involves particular work: the CORE WORK. There are ALIGNED TRAJECTORIES that feed the CORE TRAJECTORY. These are part of the CORE TRAJECTORY. The FEATURES of mobile trajectory are CYCLES, TRANSITIONS, TRAVERSALS, STREAMS, SCHEMES, POSSIBILITIES, HISTORICITY and SHAPE. The PROPERTIES are PHYSICALITY, LOCALITY, INSTRUMENTALITY, SYNCHRONICITY, INTER- DEPENDENCY, PREDICTABILITY and PALPABILITY. Important CONCERNS are RECONCILIATION CONCERNS, ALIGNMNENT CONCERNS, RECIPROCAL CONCERNS and CONTINGENCY CONCERNS. Key ASSOCIATED NOTIONS are SOCIAL SPHERES with particular WORLDS and SUB-WORLDS comprising MEMBERS with particular ROLES and INVOLVEMENT. SOCIAL SPHERES have particular BOUNDARIES, RESOURCES and MEDIA and shared KNOWLEDGE and PRACTICES. MEDIA and RESOURCES have particular AVAILABILITY and MUTABILITY. MEMBERS have particular BIOGRAPHIES, TIES and OBLIGATIONS and AWARENESS of others. Through the case material presented I demonstrate how this 'theory' supports the work of describing and discussing mobile work for the purpose of conceptualising, selecting, recommending and critically evaluating everyday Information and Communication Technologies. At the end of the thesis I compare mobile trajectory to three alternative approaches and two alternative theories with regard to supporting the same kind of work.

N. Bukauskas. Mobile Work Place for the Manager in Private Limited Liability Company “Elektronikos komponentai” Master’s thesis (advisor prof. G. Kulvietis – Šiauliai, Šiauliai University, Faculty of Physics and Mathematics, Department of Computer Science, 2005, 32 pages). In a theoretical chapter of the Master thesis, the conception of mobility and mobile work place is analysed, equipment and software for equipping the mobile work place are discussed as well as mobile solutions introduced by Lithuanian companies are reviewed. Aim of the practical chapter is to equip the mobile work place (places) in Private Limited Liability Company “Elektronikos komponentai”. In order to achieve this goal, work analysis for the employees in every unit has been performed. The general aim of the analysis is to understand and assimilate the problem prior to its realisation. Upon analysis of the work in the sales unit, it was noticed that the largest amount of “manual” work is in this unit, because it is in particular its employees, who due to their work type, spend most of the time not inside the company, but outside its limits. Namely due to these reasons, the sales unit was selected for equipping the mobile work place. After the work analysis of the sales unit, a model of the mobile work place for the manager was created. In order to realise this model, most suitable is a laptop and mobile telephone with General Packet Radio Service (GPRS). According to the requirements set for this task... [to full text]

This thesis explores the digital opportunities at a mobile workplace in elderly home care by analyzing the existing information and communication flow that happens between and during shifts in everyday practice using a user-centric approach. The fieldwork analysis reveals that a combination of media, both verbal, digital and paper-based is used throughout the shift to pick up and pass on information. With an ageing population that requires care from home, to sustain and improve the quality of care, my research indicates an evident need of supporting home care workers whilst being out of office.The research question is: “How might we decrease the amount of information lost between and during night shifts through implementing a digital alarm register?” which evolved from one out of four design opportunities.The main participants and focus throughout this study are the end-users, night shift home care workers at two different locations in the Malmö municipality. By involving the users early in the process, having a rich fieldwork process and putting emphasis on “support” rather than “replacement” resulted in a mobile application tool presenting relevant patient information, current alarms and alarm history.

<p dir="ltr">The transportation system is facing serious safety concerns at work zones and intersections, which are two major areas where accidents and fatalities occur. In addition, slow improvement in transportation industry workers’ performance is also a bottleneck to overall productivity. This dissertation aims to integrate artificial intelligence and human factors to improve the safety of mobile work zones and unsignalized intersections and monitor real-time worker’s performance.</p><p dir="ltr">To improve work zone safety, the Autonomous Truck Mounted Attenuator (ATMA) technology is explored with support from the Indiana Department of Transportation (INDOT). The ATMA can be driven automatically which removes drivers from the TMA truck to improve their safety. In this study, the ATMA system was tested under four mobile work zone operations, including trash pickup, crack sealing, Raised Pavement Marking (RPM) inspection, and drainage inspection with several roadway types, including interstate, trunk highway, and state road. During the testing, video, motion, and physiological data from the workers is collected. The data is used to develop models for transportation construction workers’ activity classification and physical fatigue level monitoring using various machine learning techniques. In addition, workers’ perception of the ATMA system is collected by a survey and the results found that more training or exposure to the ATMA system improved their evaluation of the system.</p><p dir="ltr">To improve unsignalized intersection safety, an in-vehicle warning system is developed and evaluated under various levels of aggressive vehicle behaviors across different warning conditions through a driving simulator study. A customized driving simulator is developed to support human driving experiment, which integrates SUMO and Webots. A real-world roundabout is built and calibrated in the simulator and both driving performance and eye movement data are collected from the experiments. The results indicate that advanced warnings can effectively influence vehicle speed, steering wheel control, and drivers’ attention on different areas of interests (AOIs). It is found that a proper warning time is critical to improve drivers’ safety and comfort. Gender differences are also identified from both types of data. Interestingly, although male drivers and female drivers demonstrate different driving behaviors, their safety performance in terms of minimum time to collision (TTC) is similar. Finally, to better facilitate the design of the advanced warning systems, two machine learning models are developed to predict minimum TTC and classify drivers’ perceived risk.</p><p dir="ltr">The contributions of this dissertation are summarized from the following four perspectives. First, this dissertation contributes to the body of knowledge by using a Deep Learning (DL)-based model for mobile work zone workers’ activity classification. The dissertation also innovatively integrates domain knowledge to refine the DL-based model’s performance. Second, this dissertation advances the application of feature-level data fusion in monitoring transportation construction workers. Specifically, the feature-level data fusion between kinematic and physiological data is found effective in improving model accuracy. Third, to improve mobile work zone safety, the ATMA system is tested with various road maintenance activities. This is the first ATMA test with a focus on mobile work zone operations with human workers working on the ground. The testing results are valuable for the future ATMA design and implementation. Fourth, this dissertation discloses the positive impacts of in-vehicle warning systems in roundabout merging scenarios. Furthermore, a customized driving simulator is developed to support human driving simulation experiments and is open-sourced for public use.</p>

Today’s world is characterised by a heavy dependence on information technology and technological devices to perform even the simplest of tasks. While this in itself is not a bad thing, our over dependence and neglect has put us in a situation where the confidentiality, integrity and availability of our information resources are continuously being questioned. ENISA (2010) report that in the third quarter of 2010 eighty million Smartphones were sold worldwide, with the UK, Germany, France, Spain, and Italy reporting a sixty million increment in the number of smartphone users. Reardon (2007) additionally predicted that between 2007 and 2012 there was going to be a 30% year-on-year growth in the sale of smartphones. The improvement of smartphones together with its rapidly decreasing unit price has placed smartphones within the reach of all employees. Due to the mobile nature of the device, it has brought challenges to the information security needs of organizations. As the sale of smartphone continue to increase so does the number of vulnerabilities on mobile operating systems. Knowing where to place the smartphone is of prime importance in this study. Is it just a socio-technical tool for private use or it must be extended to be used as a working tool? If so, how should it be used to limit the exposure of organizational information? The study makes use of interviews in finding out what users of the device think about the device and how secure they think their device is. The interviews also tries to find out how securely the users have configured their devices, their mobility rate and what policies have been put in place to help guide users of the device while using the device. Findings from this study indicate that smartphone threats are diverse, complicated and smart. As the price of the smartphone reduces and their functionality improves, the number of its users increases. This makes it a target for hackers and malware as they can exploit the device to gain personal and organizational data. In spite of this, the perception of users on the risks of using a smartphone for work is not as high as can be. Users still think that if only the phone is used for making and receiving calls, reading and replying to emails and checking calendar schedules, then there is nothing much to protect. In reality this is not the case. Smartphones have a lot more going on them than just the aforementioned. Users must be educated on the reality of the matter and be made aware of the current risks there are so as to increase their consciousness on this matter. Finally, the discussion in this study sheds some light on the challenges that mobility and smartphone usage for work pose to organizational information security. The choice of a counter measure depends on factors such as what kind of data the organization produces as well as what kind of usage patterns employees have. There is no one size fit all counter measure that can be implemented. Organizations must realize this and embark on the best solutions that are suitable for their organization. To get the best counter measures in place, organizations are advised to make their own risk assessments and weigh the risks against the potential benefits in their own specific cases. / <p>Validerat; 20130827 (global_studentproject_submitter)</p>

No. of bitstreams: 1 Rosemary Francisco_.pdf: 7758052 bytes, checksum: 44ca1c4c6afa003c13d4783f220148be (MD5) Previous issue date: 2017-06-30 / Nenhuma / Mobile workers are professionals who frequently work on the move, far from a fixed workplace, often performing knowledge-intensive activities. Mobility brings challenges to the processes of knowledge creation and sharing of these workers, and the existing literature lacks theoretical frameworks to explain these phenomena. Considering this gap, this study seeks to answer the following research question: How knowledge creation and knowledge sharing are carried out in collaborative problem-solving situations in the mobile workers’ context? The primary purpose of this investigation is to analyse how knowledge creation and knowledge sharing are carried out in collaborative problem-solving situations in the mobile workers’ context. To reach the research goals, this study applied Activity Theory (AT) and its key concepts as a theoretical lens. This theoretical approach allowed better understanding both the individual (the mobile worker) as well as his relations in his/her social context. Besides, the adoption of the Design Science Research method (DSR) provided tools for a deeper understanding of the research problem and also to propose an approach to stimulate knowledge creation and sharing through collaborative problem-solving in the mobile workers’ context. The results of this study helped to understand the fundamental needs of mobile workers related to knowledge creation and knowledge sharing to solve work problems. It was observed that these workers use their ICT tools, especially mobile ICT, to conduct the majority of their collaborative problem-solving situations and subsequently, to create and share knowledge on the move. The findings also highlight how mobile technologies are used to support collaborative problem-solving in the mobile work’ context. Therefore, the key argument tested and supported in this thesis is that collaborative problem-solving mediated by mobile ICT can support and stimulate knowledge creation and knowledge sharing in the context of mobile workers. This research makes a theoretical contribution by exploring this key argument with the use of AT as a theoretical lens. Since this theory was not used so far to analyse practices of knowledge creation and sharing in the context of mobile workers, this study contributes to the expansion of this theory in this subject. The results of the empirical data also provided lessons from the practice that can contribute to the theory, mainly considering the diversity of workplaces that mobile workers can use to perform their work activity. Also, this study provides methodological and practical contributions; through a detailed descriptive of how to apply the DSR in IS (Information Systems) studies, in addition to the artifact developed that can be used in practice. Finally, this study addresses some questions that can be explored in future research. / Trabalhadores móveis são profissionais que freqüentemente trabalham em movimento, longe de um local de trabalho fixo, muitas vezes realizando atividades intensivas em conhecimento. A mobilidade traz desafios aos processos de criação e compartilhamento de conhecimento para esses trabalhadores, e a literatura existente carece de frameworks teóricos para explicar esses fenômenos. Considerando esta lacuna, este estudo procura responder à seguinte pergunta de pesquisa: Como a criação e o compartilhamento de conhecimento são realizados em situações colaborativas de resolução de problemas no contexto dos trabalhadores móveis? O objetivo principal deste estudo é analisar como a criação e o compartilhamento do conhecimento são realizados em situações colaborativas de resolução de problemas no contexto dos trabalhadores móveis. Para alcançar os objetivos da pesquisa, este estudo aplicou a Teoria da Atividade (AT) e seus conceitos-chave como uma lente teórica. Esta abordagem teórica permitiu uma melhor compreensão tanto do indivíduo (o trabalhador móvel) quanto das suas relações no seu contexto social. Além disso, a adoção do método de pesquisa Design Science Research (DSR) proporcionou ferramentas para uma compreensão mais profunda do problema de pesquisa e também para propor uma abordagem para estimular a criação e o compartilhamento do conhecimento por meio da colaboração na resolução de problemas no contexto dos trabalhadores móveis. Os resultados deste estudo ajudaram a compreender as necessidades fundamentais dos trabalhadores móveis em relação à criação e ao compartilhamento de conhecimento para a resolução de problemas de trabalho. Observou-se que esses trabalhadores utilizam suas ferramentas de TIC, especialmente as TIC móveis, para conduzir a maioria de suas situações colaborativas de resolução de problemas e, posteriormente, criar e compartilhar conhecimento em movimento. Os resultados também destacam como as tecnologias móveis são usadas para apoiar a resolução colaborativa de problemas no contexto do trabalho móvel. Portanto, o principal argumento testado e suportado por esta tese, indica que a resolução colaborativa de problemas, mediada por TICs móveis, pode apoiar e estimular a criação e o compartilhamento do conhecimento no contexto de trabalhadores móveis. Esta pesquisa faz uma contribuição teórica explorando este argumento chave com o uso de AT como uma lente teórica. Uma vez que esta teoria não foi utilizada até agora para analisar as práticas de criação e compartilhamento de conhecimento no contexto dos trabalhadores móveis, este estudo contribui para a expansão desta teoria neste assunto. Os resultados empíricos também forneceram lições da prática que podem contribuir para a teoria, considerando, principalmente, a diversidade de locais de trabalho que os trabalhadores móveis podem usar para realizar suas atividades de trabalho. Além disso, este estudo fornece contribuições metodológicas e práticas; por meio de um descritivo detalhado de como aplicar o DSR em estudos de SI (Sistemas de Informação), além do artefato desenvolvido que pode ser usado na prática. Finalmente, este estudo endereça algumas questões que podem ser exploradas em futuras pesquisas.

ICTs have enabled increased mobility and created a new era of workplace connectivity. Due to changes in work organization, global operations, increased mobility, and the new opportunities they are creating; work requires more coordination, more travel and a higher frequency of boundary spanning. ICTs have infiltrated into the personal life of individuals, while similarly, having an increasing impact on how organizations manage their workers‘ work-life balance. This research investigates the work boundary negotiation process in ICT-enabled work.Using an in-depth case study supplemented with visual data, this thesis studies the case of Sigma, an international consulting firm, that serves clients located in a large geographical area. It explores how consultants exhibiting mobile work practices, use ICTs to negotiate work boundaries. It draws on the structurational model of technology and complements it with the boundary object construct. The utilisation of this combined approach allows further understanding of work boundary negotiation.The research reveals that some ICTs as technological artefacts are boundary objects bridging between different groups of actors, crossing work boundaries, and allowing actors to negotiate their work boundaries while challenging traditional boundaries. Thus, allowing consultants to use their ICTs (specifically their smartphone) to negotiate their work boundaries on a need to basis. The boundary negotiation process (as revealed by the structuration process) is the means by which consultants try to make the most out of existing social structures – in this case specifically domination – in their organizational context. The ICT becomes a source of power and is mainly used to manifest domination over available resources. Consultants use them to maintain control over their life, increase their legitimacy and convey that they are professional experts. ICTs allow consultants to continuously redefine their work boundaries which become dynamic, fluid and contextual; the research reaffirms the sociotechnical nature of work boundaries.The thesis also develops a conceptual model of work boundary negotiation that conceptually illustrates how boundary negotiation is the outcome of the structuration process and the negotiation of existing structures of domination, legitimation and signification.
