Full textAbstract:
Approved for public release; distribution is unlimitedThe Field Information Support Tool (FIST) is a field-based collection system using commercial-off-the-shelf (COTS) smartphones, customized software, and a robust information management backend known as FusionPortal with a deployable sensor fusion system known as FusionView that enables information to flow from the point of capture to an analyst in near real-time regardless of location or physical proximity. FIST is designed to operate in a variety of environments and supports a variety of mission sets such as counterinsurgency operations (COIN), counter-narcotic missions (CN), and humanitarian assistance and disaster response (HA/DR). The overarching principle of FIST is the development of a user-friendly data collection tool that utilizes automated information systems to enable unstructured data to be collected, processed, and structured for analysis and visualization in a variety of analytic packages. FusionView enables real-time integration of disparate sensor systems that provides a powerful common operating picture critical for today's decision makers. FusionPortal allows for data to be exported and analyzed using geospatial, geo-statistical, link, and social network analysis in addition to enabling the exchange of information with external databases such as the Worldwide Civil Information Database (WCID), the International Studies of Violent Groups (ISVG), and the Combined Information Data Network Exchange (CIDNE).

Sociala medier och IT support, två områden som det ofta pratas om. Allt fler företag väljer att kombinera dessa två och låta sina kunder kontakta dem då de behöver IT support via sociala medier, detta fenomen kallas ’Social IT support’. Många människor, använder dagligen sociala medier dock är det oklart vad användare anser om att söka IT support via sociala medier. Denna uppsats syftar till att undersöka hur användaren ser på att söka IT support via sociala medier samt vid vilket tillfälle de hellre skulle använda sig av traditionell IT support så som telefon och e-post samt om användaren förräntar sig snabbare respons från företaget då de söker IT support via sociala medier. Undersökningarna som genomförts har syftat till att undersöka och granska vad verkliga individer tycker och tänker kring ämnet. Undersökningarna som genomfört har bestått av en strukturerad kvantitativ enkät med 102 respondenter samt en semi strukturerad kvalitativ intervju som har genomförts på fem individer. Resultatet som framkommit av undersökningen visar att majoriteten av respondenterna är positivt inställda till att prova på att söka IT support via sociala medier. Undersökningen visar också att det är de olika problemen som uppstår som påverkar om de väljer att söka IT support via sociala medier eller på det traditionella sättet. Resultatet visar även att de flesta respondenter förväntar sig snabbare kontakt från företaget då de sökt IT support via sociala medier än över telefon. Vilket är känt från tidigare forskning dock har skillnader från tidigare forskningar påträffats. Undersökningen visar även att män har högre förväntningar än kvinnor på hur lång tid det ska ta för ett företag att kontakta dem.

The opportunity exists for the DoD's private aircraft operation, the Joint Operational Support Airlift Center (JOSAC), to utilize some of the same system features used in commercial operations such as NetJets to improve operations. This thesis will analyze the use of commercial air operator strategies and DSS's to be used in JOSAC to improve operational effectiveness. It will look to add new capabilities and processes used in commercial DSS's along with the implementation of the disruptive technology, microjets. Some of the potential benefits include improved operational performance, solutions to scheduling inefficiencies and improved mission readiness. With these improvements the potential for a military microjet operation in the future is a real possibility.

Bellenger, Amandine. "Semantic Decision Support for Information Fusion Applications." Phd thesis, INSA de Rouen, 2013. http://tel.archives-ouvertes.fr/tel-00845918.
Full textAbstract:
This thesis is part of the knowledge representation domain and modeling of uncertainty in a context of information fusion. The main idea is to use semantic tools and more specifically ontologies, not only to represent the general domain knowledge and observations, but also to represent the uncertainty that sources may introduce in their own observations. We propose to represent these uncertainties and semantic imprecision trough a metaontology (called DS-Ontology) based on the theory of belief functions. The contribution of this work focuses first on the definition of semantic inclusion and intersection operators for ontologies and on which relies the implementation of the theory of belief functions, and secondly on the development of a tool called FusionLab for merging semantic information within ontologies from the previous theorical development. These works have been applied within a European maritime surveillance project.

Full textAbstract:
Compressed sensing is a data acquisition technique that entails recovering estimates of sparse and compressible signals from n linear measurements, significantly fewer than the signal ambient dimension N.
In this thesis we show how we can reduce the required number of measurements even further if we incorporate prior information about the signal into the reconstruction algorithm. Specifically, we study certain weighted nonconvex Lp minimization algorithms and a weighted approximate message passing algorithm.
In Chapter 1 we describe compressed sensing as a practicable signal acquisition method in application and introduce the generic sparse approximation problem. Then we review some of the algorithms used in compressed sensing literature and briefly introduce the method we used to incorporate prior support information into these problems.
In Chapter 2 we derive sufficient conditions for stable and robust recovery using weighted Lp minimization and show that these conditions are better than those for recovery by regular Lp and weighted L1. We present extensive numerical experiments, both on synthetic examples and on audio, and seismic signals.
In Chapter 3 we derive weighted AMP algorithm which iteratively solves the weighted L1 minimization. We also introduce a reweighting scheme for weighted AMP algorithms which enhances the recovery performance of weighted AMP. We also apply these algorithms on synthetic experiments and on real audio signals.

Knoth, Petr. "Linking textual resources to support information discovery." Thesis, Open University, 2015. http://oro.open.ac.uk/42677/.
Full textAbstract:
A vast amount of information is today stored in the form of textual documents, many of which are available online. These documents come from different sources and are of different types. They include newspaper articles, books, corporate reports, encyclopedia entries and research papers. At a semantic level, these documents contain knowledge, which was created by explicitly connecting information and expressing it in the form of a natural language. However, a significant amount of knowledge is not explicitly stated in a single document, yet can be derived or discovered by researching, i.e. accessing, comparing, contrasting and analysing, information from multiple documents. Carrying out this work using traditional search interfaces is tedious due to information overload and the difficulty of formulating queries that would help us to discover information we are not aware of. In order to support this exploratory process, we need to be able to effectively navigate between related pieces of information across documents. While information can be connected using manually curated cross-document links, this approach not only does not scale, but cannot systematically assist us in the discovery of sometimes non-obvious (hidden) relationships. Consequently, there is a need for automatic approaches to link discovery. This work studies how people link content, investigates the properties of different link types, presents new methods for automatic link discovery and designs a system in which link discovery is applied on a collection of millions of documents to improve access to public knowledge.

The coming future will decide which universities would survive the market trends, competition and expectations of the students (Clients). The survival-of-the-fittest paradigm framework plays a prominent role in ideas of how the higher education would be delivered to the students in future with the Instruction Technology and distance education. According to us the education trend has changed its phase of delivery of services form the management point of view to student’s point of view.Leading to delivery of educational service’s which would have more impact on student’s education, knowledge and experience within the institution. In our thesis we try to provide some information about how to support and manage the information in Virtual Organizations. We also explore the frameworks of the university and discussed a case study about the different ways of providing better support for information management resulting in delivery of best students driven services and unique facilities. We would be looking at the different aspects of the university work flows and procedures and gain an insight on the student’s expectation from the organization. This investigation would be helpful for the students to know what are the services they should expect from the universities and also helpful for management to know better the needs of the students and their needs and to develop a framework for proper execution of these services.In an educational environment students should be the first priority. Trusting students is we feel the most important aspect of an educational institution also providing the best possible support to students.after being through the total framework of an organization and different Non- Functional requirements, we conclude that the primary task for better information management and service delivery in any organization is to get the better understanding of the requirements engineering. An organization should have clearly defined stakeholders who would be qualified and filled with commitment to manage their responsibilities with higher priority; also they have to take up the responsibilities for the students.So to achieve a balance among stakeholders there should be a proper negotiation and communication between the stakeholders. In order to achieve that there should be common set of defined rules (say services) through which they could correspond with each other. The stakeholder should be well equipped with the technical nature used to develop and maintain the system.In short the management is the key player in understanding and validating the system and determine whether or not the existing system/process is in control. The most powerful designs are always the result of a continuous process of simplification and refinement. The system could be validated by taking regular feedback from students by handing out a paper for evaluation at various occasions of the different courses. An online, end-of-course plus the experiences of students questions should be designed and should be made a part of students work to fill it in order to get their right perception on the system. These feedbacks could lead to proper student dialogue evaluation. Therefore, eventually controlling and smoothly managing the stakeholders and the services could provide efficient support for the information management in virtual organizations.BTH has the staffs who are concerned about student problems but there is no person responsible for the students whom the students could approach. So BTH should have defined stakeholders who are responsible for the students and to whom the students could approach with their difficulties and problems. The university should show the students that they care for them, this is only possible by the university to go an extra mile for the sake of students and providing better facilities and future prospects for the students.

Artificial Intelligence Lab, Department of MIS, University of ArizonaObservations of Information Retrieval (IR) system user experiences reveal a strong desire for collaborative search while at the same time suggesting that collaborative capabilities are rarely, and then only in a limited fashion, supported by current searching and visualization tools. Equally interesting is the fact that observations of user experiences with Group Support Systems (GSS) reveal that although access to external information and the ability to search for relevant material is often vital to the progress of GSS sessions, integrated support for collaborative searching and visualization of results is lacking in GSS systems. After reviewing both user experiences described in IR and GSS literature and observing and interviewing users of existing IR and GSS commercial and prototype systems, the authors conclude that there is an obvious demand for systems supporting multi-user IR.. It is surprising to the authors that very little attention has been given to the common ground shared by these two important research domains. With this in mind, our paper describes how user experiences with IR and GSS systems has shed light on a promising new area of collaborative research and led to the development of a prototype that merges the two paradigms into a Collaborative Information Retrieval Environment (CIRE). Finally the paper presents theory developed from initial user experiences with our prototype and describes plans to test the efficacy of this new paradigm empirically through controlled experimentation.

Full textAbstract:
Gift giving has far deeper societal, sociological, and psychological implications than people are generally aware of. It can work in both positive and negative ways — building and strengthening or weakening and breaking social ties, imposing identity images on both the givers and the recipients. Gifts are also important from a consumer and marketing perspective, and tend to cause their seekers anxiety in many ways.
To counter the difficulties in the gift giving process it is important to record information about important dates, recipients, given and received gifts, as well as new plans. Many tools are already being used to help keep track of gift giving, and these range from simple pen-and-paper solutions to productivity applications like note-taking tools and spreadsheets.
The purpose of this thesis is to explore gift giving behaviour and make use of the Technology Acceptance Model to triangulate requirements for a gift giving support application, as well as offer a list of possible design contributions to meet each requirement. These results can then be utilised in future research to design and produce an actual gift giving support application, that will meet the needs of both gift givers and recipients.

Full textAbstract:
In the light of an ageing society with shrinking economic resources, deinstitutionalization of elderly care is a general trend. As a result, homecare is increasing, and increasingly shared between different health and social care organizations. To provide a holistic overview about the patient care process, i.e. to be patient-centred, shared homecare needs to be integrated. This requires improved support for information sharing and cooperation between different actors, such as care professionals, patients and their relatives. The research objectives of this thesis are therefore to study information and communication needs for patient-centered shared homecare, to explore how integrated information and communication technology (ICT) can support information sharing, and to analyze how current standards for continuity of care and semantic interoperability meet requirements of patient-centered shared homecare. An action research approach, characterized by an iterative cycle, an emphasis on change and close collaboration with practitioners, patients and their relatives, was used. Studying one specific homecare setting closely, intersection points between involved actors and specific needs for information sharing were identified and described as shared information objects. An integration architecture making shared information objects available through integration of existing systems was designed and implemented. Mobile virtual health record (VHR) applications thereby enable a seamless flow of information between involved actors. These applications were tested and validated in the OLD@HOME-project. Moreover, the underlying information model for a shared care plan was mapped against current standards. Some important discrepancies were identified between these results and current standards for continuity of care, stressing the importance of evaluating standardized models against requirements of evolving healthcare contexts. In conclusion, this thesis gives important insights into the needs and requirements of shared homecare, enabling a shift towards patient-centered homecare through mobile access to aggregated information from current feeder systems and documentation at the point of need.

Full textAbstract:
People’s activities on the internet have expanded from mainly retrieving information to communicating with each other in virtual settings. Thus, research investigating social interactions in online communities is becoming more and more important. However, the multi-faceted approaches of existing studies for the analysis of online communities make it difficult to combine the findings into a comprehensive understanding. This shows the need for holistic investigations of online communities. This thesis provides such a holistic approach by investigating a combination of different aspects of a selected online support community for older people. MOSuC (Model of Online Support Communities), a model describing the key aspects of online support communities was developed based on existing theories of computer-mediated communication (CMC) as well as theoretical perspectives on social support. Five studies were conducted, each addressing one of the different aspects of the case study community: (i) the message content, (ii) the conversations structure, (iii) the social network of related community members, (iv) the roles that online community members take on, and (vi) the taget population’s needs concerning the exchange of social support in online communities. The findings of these individual studies were then combined in context of MOSuC in order to provide a holistic description of the community. As a result, this thesis provides detailed insight into the characteristics of the case study community as well as the interplay and dependencies between different aspects of the community. Based on the integration of multiple studies, the thesis sheds light on two main issues: the characteristics of the individual aspects of the community as well as how these aspects are related to and affect each other. In addition to the findings of the studies, the thesis also contributes MOSuC, which serves both as a theoretical framework of the aspects of online support communities, as well as a practical tool for integrating the individual studies. In addition, the application, modification and integration of multiple methods in this thesis provide a novel methodological way for an integrative analysis of online support communities.

Full textAbstract:
This work develops novel algorithms for incorporating prior-support information into the field of One-Bit Compressed Sensing. Traditionally, Compressed Sensing is used for acquiring high-dimensional signals from few linear measurements. In applications, it is often the case that we have some knowledge of the structure of our signal(s) beforehand, and thus we would like to leverage it to attain more accurate and efficient recovery. Additionally, the Compressive Sensing framework maintains relevance even when the available measurements are subject to extreme quantization. Indeed, the field of One-Bit Compressive Sensing aims to recover a signal from measurements reduced to only their sign-bit. This work explores avenues for incorporating partial-support information into existing One-Bit Compressive Sensing algorithms. We provide both a rich background to the field of compressed sensing and in particular the one-bit framework, while also developing and testing new algorithms for this setting. Experimental results demonstrate that newly proposed methods of this work yield improved signal recovery even for varying levels of accuracy in the prior information. This work is thus the first to provide recovery mechanisms that efficiently use prior signal information in the one-bit reconstruction setting.

This thesis describes a scalable system for visualizing and exploring global synthetic populations. The implementation described in this thesis addresses the following existing limitations of the Syn- thetic Information Viewer (SIV): (i) it adds ability to support synthetic populations for the entire globe by resolving data inconsistencies, (ii) introduces opportunities to explore and find patterns in the data, and (iii) allows the addition of new synthetic population centers with minimal effort. We propose the following extensions to the system: (i) Data Registry: an abstraction layer for handling heterogeneity of data across countries, and adding new population centers for visualizations, and (ii) Visual Query Interface: for exploring and analyzing patterns to gain insights. With these additions, our system is capable of visual exploration and querying of heterogeneous, temporal, spatial and social data for 14 countries with a total population of 830 million. Work in this thesis takes a step towards providing visual analytics capability for synthetic information. This system will assist urban planners, public health analysts, and, any individuals interested in socially-coupled systems, by empowering them to make informed decisions through exploration of synthetic information.Master of Science

Full textAbstract:
The main objective of the framework we are proposing
is to help the physician obtain information about the patient's condition in order to reach the \emph{correct} diagnosis as soon as possible.
In our proposal, the number of interactions between the physician and the patient is reduced to a strict minimum on the one hand and, on the other hand, it is made possible to increase the number of questions to be asked if the uncertainty about the diagnosis persists.
These advantages are due to the fact that (i) we implement a reasoning component that allows us to predict a symptom from another symptom without explicitly asking the patient, (ii) we consider non-binary values for the weights associated with the symptoms, we introduce a dataset filtering process in order to choose which partition should be used with respect to some particular characteristics of the patient, and, in addition, (iv) it was added new functionality to the framework: the ability to detect further future risks of a patient already knowing his pathology.
The experimental results we obtained are very encouraging

qualitative opportunity to integrate various participants in logistics processes into a single system, exceeding the traditional boundaries of enterprises and reaching national and international boundaries. However, in such integrated systems the requirements of operational management of material flows are actualized, which
means the need to ensure parallelism in time of material and information flows, i.e. to ensure the collection, processing and transmission of information in real time. The creation of multi-level automated material flow management systems, although it requires significant costs for software development and database
formation, on the one hand, should ensure the versatility of the system, and on the other - a high level of integration of all supply chain participantsШироке проникнення логістики в економіку стало можливим значною мірою завдяки комп’ютеризації управління матеріальними потоками.

Many universities, libraries, government organisations and companies are implementing digital repositories to collect, preserve, administer and distribute their collections via the World Wide Web. In the process of building these digital archives and collections, images such as maps are often are captured in an uncompressed, high-resolution format to preserve as much detail as possible. This process, of high-resolution archiving gives rise to the problem of providing the end-user with access to these large (high-resolution) images, such as maps. This dissertation investigates methods of storing and delivering large images over the Internet while limiting the amount of data being transferred; and also documents efforts to incorporate large image support within the DSpace platform.

IT and global digitization has quickly reached our society and the development of technology has been very fast. When IT came to the school it put new demands on IT-support, and the new requirements are difficult to meet. Many teachers feel that there are major deficiencies related to IT-support and assistance, therefore, this study has chosen to focus on how schools can be adapted to today's IT society and develop sustainable models for IT-support and assistance. With the support of my own experiences, other reports, articles and interviews, this study contribute to school development by analyzing IT-technicians and supporting/ assisting teachers’ situation. There is a lack of understanding of the actual practice in the schools need of IT. IT-support and or assistance can be improved by information, education, increased self-service, efficient and suitable support. This study has highlighted many areas and perhaps giving a glimpse of what kind of IT-support and assistance schools will need.

Full textAbstract:
Gift giving has far deeper societal, sociological, and psychological implications than people are generally aware of. It can work in both positive and negative ways — building and strengthening or weakening and breaking social ties, imposing identity images on both the givers and the recipients. Gifts are also important from a consumer and marketing perspective and tend to cause their seekers anxiety in many ways.
To counter the difficulties in the gift giving process it is important to record information about important dates, recipients, given and received gifts, as well as new plans and ideas. Many tools are already being used to help keep track of gift giving, and these range from simple pen-and-paper solutions to productivity applications like note-taking tools and spreadsheets. Unfortunately, there are only a few tools that specialise in gift management, and even these have shortcomings in one way or another.
The purpose of this thesis was to design a new and better solution to meet gift giving management needs. Gift giving behaviour was explored through literature and interviews, and the Technology Acceptance Model and Design Science Research approach were utilised to triangulate a complete list of requirements for a gift giving support application, which was then designed. A prototype was constructed according to the design. The prototype was evaluated with heuristic evaluation and small-scale user testing using a paper prototype. The findings were used to correct flaws in the initial design, resulting in an improved design of the proposed application. While nowhere near ready for production, the prototype could stand up to evaluation against requirements on an acceptable level, thus validating the design approach.
These results can be utilised in future research and/or development to continue the design and production of an actual gift giving support application that will meet the needs of both gift givers and recipients.

Full textAbstract:
Patient data in health care have traditionally been used to support direct patient care. Although there is great potential in combining such data with genetic information from patients to improve diagnosis and therapy decisions (i.e. personalized medicine) and in secondary uses such as data mining, this is complex to realize due to technical, commercial and legal issues related with combining and refining patient data. Clinical decision support systems (CDSS) are great catalysts for enabling evidence-based medicine in clinical practice. Although patient data can be the base for CDSS logic, it is often scattered among heterogenous data sources (even in different health care centers). Data integration and subsequent data mining must consider codification of patient data with terminology systems in addition to legal and ethical aspects of using such data. Although computerization of the patient record systems has been underway for a long time, some data is still unstructured. Investigation regarding the feasibility of using electronic patient records (EPR) as data sources for data mining is therefore important. Association rules can be used as a base for CDSS development. Logic representation affect the usability of the systems and the possibility of providing explanations of the generated advice. Several properties of these rules are relatively easy to explain (such as support and confidence), which in itself can improve end-user confidence in advice from CDSS. Information from information sources other than the EPR can also be important for diagnosis and/or treatment decisions. Drug prescription is a process that is particularly dependent on reliable information regarding, among other things, drug-drug interactions which can have serious effects. CDSS and other information systems are not useful unless they are available at the time and location of patient care. This motivates using mobile devices for CDSS. Information structures of interactions affect representation in informatics systems. These structures can be represented using a category theory based implementation of rough sets (rough monads). Development of guidelines and CDSS can be based on existing guidelines with connections to external information systems that validate advice given the particular patient situation (for example, previously prescribed drugs may interact with recommended drugs by CDSS). Rules for CDSS can also be generated directly from patient data but this assumes that such data is structured and representative. Although there is great potential in CDSS to improve the quality and efficiency of health care, these systems must be properly integrated with existing processes in health care (workflows) and with other information systems. Health care workflows manage physical resources such as patients and doctors and can help to standardize care processes and support management decisions through workflow simulation. Such simulations allow information bottle-necks or insufficient resources (equipment, personnel) to be identified. As personalized medicine using genetic information of patients become economically feasible, computational requirements increase. In this sense, distributing computations through web services and system-oriented workflows can complement human-oriented workflows. Issues related to dynamic service discovery, semantic annotations of data, service inputs/outputs affect the feasibility of system-oriented workflow construction and sharing. Additionally, sharing of system-oriented workflows increase the possibilities of peer-review and workflow re-usage.

Full textAbstract:
Extensive previous research has shown that web-based technologies have the potential to improve and enhance the quality of learning both on campus and at a distance. However, most of these studies have focused on the application of web-based technologies to support either undergraduates or taught postgraduate programmes, particularly, the use of Virtual Learning Environment (VLE) system to complement module-based courses. Evidence from previous research on the use of VLE to support research students in the context of specific modules showed mixed results. Analysis of the VLE literature suggests that the system arranges courses based on academic calendar. Thus, students will not be able to access the system after the semester end. With postgraduate research, the processes of research are often incomplete even when students have graduated and they often seek to further the work through publication in journals. Therefore, using VLE alone would not possibly support the need of research student, particularly the support that they need throughout the stages of the research life cycle. Therefore, the main aim of this study is to investigate how a web portal could be designed to support the research students throughout the research life cycle. A conceptualised web portal design has been constructed through an extensive review of the web-based technologies, learning theories and research degrees literature. The conceptualised web portal design illustrates that the design is underpinned by adult learning theories and the theory of stages in socialisation development, which in turn inform the framework of this research study. This model was then validated and updated through four action research cycles. A web portal system was developed, using the prototyping method to demonstrate the application of the web portal design informed by the adult learning theories and theory of stages in socialisation development. The research findings suggest that action research and prototyping methodology is capable of designing a web portal that is able to support the needs of research students in the context of a life cycle approach. Furthermore, the study reveals that personalisation and customisation features have proved to be useful in providing relevant information to research students at each stage of the research students’ study. It was found that research students value dynamic content such as Really Simple Syndication (RSS) features for providing condensed, updated content relevant to their interests.

The Kentucky Mesonet is a high-density, mesoscale network of automated meteorological and climatological sensing platforms being developed across the commonwealth. Data communications, collection, processing, and delivery mechanisms play a critical role in such networks, and the World Meteorological Organization recognizes that “an observing system is not complete unless it is connected to other systems that deliver the data to the users.” This document reviews the implementation steps, decisions, and rationale surrounding communications and computing infrastructure development to support the Mesonet. A general overview of the network and technology-related research is provided followed by a review of pertinent literature related to in situ sensing network technology. Initial infrastructure design considerations are then examined followed by an in-depth review of the Mesonet communications and computing architecture. Finally, some general benefits of the Mesonet to the citizens of Kentucky are highlighted.

With increasing amounts of data being generated by businesses and researchers there is a need for fast, accurate and robust algorithms for data analysis. Improvements in databases technology, computing performance and artificial intelligence have contributed to the development of intelligent data analysis. The primary aim of data mining is to discover patterns in the data that lead to better understanding of the data generating process and to useful predictions. One recent technique that has been developed to handle the ever-increasing complexity of hidden patterns is the support vector machine. The support vector machine has been developed as robust tool for classification and regression in noisy, complex domains. Current thesis work is aimed to explore the area of support vector machine to see the interesting applications in data analysis, especially from the point of view of information processing.

Full textAbstract:
In our research context, sustainable procurement can be seen as a process to reduce damage to the environment by integrating certain aspects into making procurement decisions, such as value for money throughout the whole life cycle and being of benefit to society and the economy. This research has found more than one way of interpreting the ‘sustainable system’, for example, ‘green-friendly’ versus remaining effective in the long term. Sustainable procurement requires specific information to support the procurement process. The study reported in this thesis aimed to investigate the type of information needed in order for organisations to make correct sustainable procurement decisions. From these findings, information architecture for sustainable procurement in UK universities has been derived. While the initial focus has been on the information needed to make informed decisions in purchasing sustainable information technology (IT) equipment, it is believed that the framework would also be more widely applicable to other types of purchases. To ensure that these findings would support the university aspiration in terms of sustainability practices, a goal-context modelling technique called VMOST/B-SCP was chosen to analyse the sustainable procurement strategy in order to evaluate the alignment of IT strategy and its business strategy. A goal-context model using VMOST/B-SCP was produced to evaluate the procurement strategy, with this validated by procurement staff. This research helps to improve the way that goals and context are identified by integrating another technique, namely, social network analysis (SNA) to produce actor network diagrams. The VMOST/B-SCP technique is transferrable to the mapping of action strategies. The findings from goal-context modelling show that a goal-context model is not static: it changes as external circumstances and organisational priorities change. Most changes to the strategy occurred where external entities on which the change programme depended did not act as planned. The actor networks produced in our version of VMOST/B-SCP can be used to identify such risks. This research was pioneering in its use of VMOST/B-SCP in examining a business change while it was actually taking place rather than after it had been completed (and thus needed to accommodate changes in objectives and strategies). In addition, the research analysed a system with some IT support but where human-operated procedures predominated. The original B-SCP framework used Jackson’s problem frames which focus on possible software components: in our scenario, SNA-inspired actor diagrams were found to be more appropriate.

The increasing number of web services published over the Web highlights the need for an effective method for users to find appropriate web services. Existing web service discovery methods do not effectively aid a user in finding suitable web services. The current methods provide textual lists of web services that the user is required to explore and manually evaluate. Thus, these methods lead to time-consuming and ineffective web service discovery. The aim of this research was to investigate using information visualization (IV) techniques to effectively support web service discovery. The node-and-link network IV technique was selected as the most appropriate IV technique to visualize web service collections. A prototype, called SerViz, was developed as a tool for interactive visualization of web service collections incorporating the node-and-link IV technique and an alphabetical list-based technique. SerViz used the Programmable Web web service collection as the sample web service collection. A usability evaluation was conducted to compare these techniques. Ninety percent of participants preferred the network IV technique for visualizing web service collections. The network IV technique was also faster for browsing. Several usability problems were identified with the network IV technique. This motivated a need for implementing an alternative IV technique in SerViz. The node-and-link tree IV technique was selected as it was more structured than the network IV technique. A usability evaluation was conducted to compare the network and tree IV techniques. Participants slightly preferred the tree IV technique as the technique to visualize web service collections. The tree IV technique was faster for browsing the web service collection while the network IV technique was faster for searching and filtering. This research has determined that IV techniques can be used to effectively support web service discovery. Future work will involve using IV techniques to support collaborative web service discovery. Keywords: Web Service Discovery, Information Visualization, Web Service Collections, Information Visualization Techniques.

Full textAbstract:
In recent years organizations developing information systems have started to demand that there should be an explicit connection between the rationale of the system developed and the system itself. In the "From Fuzzy to Formal" project an attempt to develop a methodology supporting this was made. Within the project a method called Enterprise Modeling was developed, aiming at creating this connection. This method contains five different sub-models. The sub-models are connected to each other by inter-model links. The models developed using EM are of high complexity. Therefore tool and repository support should be provided. To be flexible and extendible, such a tool set should be based upon a standardized meta-model. CDIF is an example of such a standard.
In this dissertation we develop a meta-model capable of capturing the information that is created using the Enterprise Modeling technique. We use the extensibility mechanism that is provided with the CDIF standard to extend the existing CDIF Integrated meta-model to support the models used in this work. We also develop a procedure supporting the mapping between the representations. Finally we discuss the functionality of a tool capable of supporting the work with the models.

Full textAbstract:
Observations in the information technology (IT) support environment and generalizations from the literature regarding problem resolution behavior indicate that computer support staff seldom store reusable solution information effectively for IT problems. A comprehensive model of the processes encompassing problem arrival and assessment, expertise selection, problem resolution, and solution recording has not been available to facilitate research in this domain. This investigation employed the findings from a qualitative pilot study of IT support staff information behaviors to develop and explicate a detailed model of problem trajectory. Based on a model from clinical studies, this model encompassed a trajectory scheme that included the communication media, characteristics of the problem, decision points in the problem resolution process, and knowledge creation in the form of solution storage. The research design included the administration of an extensive scenario-based online survey to a purposive sample of IT support staff at a medium-sized state-supported university, with additional respondents from online communities of IT support managers and call-tracking software developers. The investigator analyzed 109 completed surveys and conducted email interviews of a stratified nonrandom sample of survey respondents to evaluate the suitability of the model. The investigation employed mixed methods including descriptive statistics, effects size analysis, and content analysis to interpret the results and verify the sufficiency of the problem trajectory model. The study found that expertise selection relied on the factors of credibility, responsibility, and responsiveness. Respondents referred severe new problems for resolution and recorded formal solutions more often than other types of problems, whereas they retained moderate recurring problems for resolution and seldom recorded those solutions. Work experience above and below the 5-year mark affected decisions to retain, refer, or defer problems, as well as solution storage and broadcasting behaviors. The veracity of the problem trajectory model was verified and it was found to be an appropriate tool and explanatory device for research in the IT domain.

Full textAbstract:
Computing devices have a predominant role in our lives, changing most of our daily activities. With the advent of the IoT, more and more embedded devices are expected to be connected, with expected numbers around 20 billion of units for the 2020. Nevertheless, the increase in connectivity does not imply an enhancement of security. Programmable devices, especially connected ones, are at risk of being tampered with: recent history has shown many examples of malicious software attacks compromising their security. Considering that embedded device are required to be cheap in terms of resources they are implemented on low-end microcontrollers, which lack of any memory protection technique, making them unsuitable to implement solutions from the high-end world.Hence, researchers have been recently focusing on strategies to provide them with security guarantees that hold even in case of an attacker with full control on the system, including the Operating System (OS). A promising solution is found in Protected (software) Module Architectures (PMAs): security architectures that can execute protected code in an isolated area of the memory, inaccessible to other software. PMAs can support secure execution of small portion of code, the software modules (SMs), even on devices that are, e.g., malware infected. The target architecture of this thesis is Sancus, an open-source, hardware-only PMA, designed for lightweight embedded devices. The objective of the work is to extend the architecture with Direct Memory Access (DMA) support, a feature that provides peripherals with a secondary channel to access the memory without involving the CPU, and to explore what does it entail from a security prospective. Usually lightweight PMAs do not support DMA, as the benefits coming from its inclusion on the system do not comply with security properties of these architectures: protected memory isolation and confidentiality are no longer guaranteed if a secondary channel, that directly access the memory independently from the CPU, is provided. Main achievements of the thesis are to extend the Sancus 2.0 architecture with DMA support, showing how this affects its security properties and providing a secure way to implement DMA. From the discussion of the upcoming chapters, two solutions stood out: the first one is currently implemented on Sancus, and it consists in entirely excluding DMA from accessing protected memory, preserving SMs security guarantees. The second theoretical solution aims to provide the software modules with DMA functionalities, by allowing some security guarantees for a confined regions inside protected memory. The latter solution is discussed in details and some design options are provided, whereas its implementation is deferred as future work.Datorer har en dominerande roll i våra liv och förändrar de flesta av våra dagliga aktiviteter. Med tillkomsten av IoT förväntas fler och fler inbyggda enheter anslutas, med förväntat antal cirka 20 miljarder år 2020. Ändå innebär ökningen av anslutning inte en ökning av säkerheten. Programmerbara enheter, särskilt anslutna, riskerar att bli manipulerade: de senaste erfarenheterna visar många exempel på skadliga programattacker som äventyrar säkerheten. Inbäddade enheter måste vara billiga när det gäller resurser. Därför implementeras de på low-end mikrokontrollers, som helt saknar stöd för minnesskydd vilket gör dem olämpliga för lösningar från high-end-världen. Därför har forskare nyligen fokuserat på strategier för att ge dem säkerhetsgarantier som håller även i händelse av en angripare med full kontroll på systemet, inklusive operativsystemet (OS). En lovande lösning finns i Protected (Software) Module Architectures (PMA): säkerhetsarkitekturer som kan exekvera skyddad kod i ett isolerat område i minnet, otillgängligt för annan programvara. PMA kan stödja säker exekvering av liten del av koden, mjukvarumoduler (SM), även på enheter som är infekterade och innehåller skadlig programvara. Målarkitekturen för den här avhandlingen är Sancus, en öppen källkod endast för maskinvara-PMA, avsedd för inbyggda lättviktsenheter. Syftet med arbetet är att utöka arkitekturen med DMA-stöd (Direct Memory Access), en funktion som ger perifera enheter en sekundär kanal för att komma åt minnet utan att involvera CPU, och att undersöka vad det medför från ett säkerhetsperspektiv. Vanligtvis ger inte lättvikts-PMA stöd för DMA, eftersom fördelarna som följer av att den ingår i systemet inte överensstämmer med säkerhetsegenskaperna hos dessa arkitekturer: skyddad minnesisolering och konfidentialitet garanteras inte längre om en sekundär kanal, som har direkt åtkomst till minnet oberoende av CPU, tillhandahålls. Huvud-resultatet i avhandlingen är att utöka Sancus 2.0-arkitekturen med DMA-stöd, vilket visar hur det påverkar dess säkerhetsegenskaper och ger ett säkert sätt att implementera DMA. Två lösningar presenteras: den första är för närvarande implementerad på Sancus och består helt och hållet av att DMA inte ska få tillgång till skyddat minne och bevarar säkerhetsgarantier från SM. Den andra teoretiska lösningen syftar till att tillhandahålla mjukvarumoduler med DMA-funktioner, genom att tillåta vissa säkerhetsgarantier för en begränsad region inom det skyddade minnet. Den senare lösningen diskuteras i detalj och vissa designalternativ ges, medan dess genomförande skjuts på framtiden.

Nurturing a good working environment is beneficial not only in the short term for keeping employees happy, but especially important for work-life longevity. Poor working conditions can severely lower the retirement age depending on the line of business. The Swedish Working Environment Authority (SWEA) is a governmental institution that regulates and enforces work environment laws. Currently, SWEA has issues in justifying which workplaces to choose for inspection. Therefore, they are interested in implementing statistical methods to help them make decisions about which workplaces to inspect for work environment issues. This thesis implements a prototype logistic regression model to classify workplaces as suitable to visit or not. There are two definitions for which workplaces that are visit suitable, either due to the number of deficiencies a workplace had (median group) or due to the severity of an incident at the workplace (severe group). Results are presented for both. Considering a subset of the workplaces that have been given the highest probability of being visit suitable, the prototype performed slightly better than random in the median group and significantly better than random in the severe group.Att fostra en bra arbetsmiljö är fördelaktigt inte bara på kort sikt för att de anställda ska vara nöjda, men framförallt för arbetslivslängd. Dålig arbetsmiljö kan sänka pensionsåldern rejält beroende på vilken bransch man är i. Arbetsmiljöverket (AV, här SWEA) är en statlig myndighet som förvaltar arbetsmiljölagarna och ser till att de efterföljs. AV har för tillfället problem i att underbygga valet av arbetsplatser som inspekteras. Därför är dem intresserade av att implementera statistiska metoder som kan hjälpa de att välja ut inspektionsobjekt som är lämpligast att besöka. Det här examensarbetet implementerar en prototyp som använder sig av en logistisk regressionsmodell för att klassa arbetsplatser som besöksbenägna eller ej. Det finns två definitioner av besöksbenägenhet för arbetsplatser. Antingen på grund av hur många brister den har haft (mediangruppen) eller på grund av någon allvarlig incident på arbetsplatsen (allvarliga gruppen). Resultat läggs fram för båda dessa. Om man undersöker ett urval av arbetsplatserna som blivit tilldelade störst sannolikhet att vara besöksbenägna kan man konstatera att prototypen presterade något bättre än slumpen i mediangruppen och markant bättre än slumpen i allvarliga gruppen.

Full textAbstract:
Recommendations on breastfeeding in the United States suggest that infants should be exclusively breastfed for six months with continued breastfeeding in conjunction with complementary foods for at least one year. However, only 22.30% of women are exclusively breastfeeding when their infant reaches the age of six months, which indicates the existence of barriers hindering prolonged breastfeeding. In this study, I consider the factors related to information-seeking behavior that may influence breastfeeding rates. Specifically, I focus on the relationship between the sources a woman selects to receive information about breastfeeding and her level of breastfeeding self-efficacy, which has been shown to be a significant predictor of breastfeeding success. A sample of 222 breastfeeding women was recruited for participation in this study. Participants completed a mixed-methods survey, and the results of the survey were analyzed using applied thematic analysis, correlation, and regression analysis. Women who participated in this study used non-expert online information sources most frequently when searching for information related to breastfeeding. Criteria women used most frequently when choosing an information source included source affordances (e.g., convenience and quickness), information characteristics (e.g., variety of information and information quality), and source characteristics (e.g., source expertise). Hypotheses for this study posited a relationship between source characteristics (i.e., expertise, trustworthiness, goodwill, and social support) and breastfeeding self-efficacy; all hypotheses were supported, and expertise, trustworthiness, goodwill, and social support were found to have a significant positive relationship with breastfeeding self-efficacy. Source expertise was found to be the strongest predictor of breastfeeding self-efficacy among those that were measured for this study; however, it is not an individual significant predictor when modeled alongside the remaining source characteristics. Implications of this study stress the importance of access to quality information related to breastfeeding and continued research on the development of breastfeeding self-efficacy in various demographic populations and over the span of a breastfeeding relationship.

Full textAbstract:
While today's police forces are decreasing in number and their resources are limited, population is at the same time increasing. This means that other types of efforts and strategies are needed to fight crime. There are different strategies to do this, one of which is called community policing that involves proactive cooperation between citizens and the police to deal with the problems. Traditionally, community policing meant that a local police in the neighbourhood called for physical meetings, where citizens and police together raised problems and discussed solutions to these. With today's limited resources, there is little possibilities for the police to execute this kind of physical collaboration and meetings. On the other hand, another meeting place has been added (the one online) and an alternative way to implement community policing may be online. With digital channels for this purpose, there may also be an opportunity to reach groups of citizens that the police have not reached before, but in order to do so, it requires work and a use of these digital channels in the right way according to community policing. The purpose of this paper is to investigate what challenges and requirements that needs to be taken into consideration when implementing community policing with the support of digital communication channels. For this purpose, qualitative research in the form of literature studies and semi-structured interviews were conducted. Findings show there are a lot of challenges and requirements to consider and there are guidelines in the analysis and discussion section, to help begin to implement this way of working. The practical implications for this thesis may help police improving their relationships with citizens in vulnerable areas to be able to cooperate according to community policing to make these areas a better and safer place to live.
