Discover how it is now possible to memory-link all man-in-the-loop and machine-in-the-loop elements, as global resources that share information at memory-access speeds, to provide a unified system paradigm that avows: "the data is there, on time, every time." Regardless of configuration, if your past, present, or future system consists of more than one computer, and it interactively mixes information sources and destinations (e.g. Telemetry data streams, I/O interfaces, information processors, etc.) to achieve a highly integrated system, then the critical path to real-time success mandates a high performance, reliable, and deterministic communications methodology. This softwareless, future technology is already successfully sharing information in other real-time markets and applications, and is ready for more challenging applications.

Abstract:

Despite continuous advancements in mobile communication technologies, there are rural areas even in developed countries like Sweden that still lack basic forms of connectivity. Sweden’s arctic region suffer from a low cost effectiveness of mobile telecommunication infrastructures which results in a lack of cellular coverage in many areas. In response to these challenges, Tannak AB was founded by two Saami women who had their own solution for the reindeer herding industry. With Tannak’s telemetry network, reindeer are tracked with GPS-equipped collars and information is forwarded in-between base stations before transmitted through the regular cellular network. While reindeer inside these areas may now be tracked, reindeer herders still need Internet access to retrieve this information - which they in some places don’t have. This thesis explores how Tannak’s network could be further utilized to also provide limited connectivity and services to end users, primarily to allow access to tracking information directly form the network. The presented solution includes an interface to Tannak’s network in the form of portable WiFi hotspots, which would be hosted by mobile base stations in the network. The service of accessing tracking information is here implemented and tested between an Android device and a laptop controlling a WiFi module. A developed map based Android application allows viewing reindeer information both from the web and directly from the field network. Furthermore, introducing a power saving schedule specifically adapted to the delay-tolerant nature of the tracking network has shown to decrease hourly battery consumption of the WiFi module by 4/5 to merely 6.8 mAh. This is compared to not using the power schedule, while doing four transmissions per hour over the WiFi interface. The results indicate that the solution could be a valid approach as an end user interface to the tracking system. Based on the properties of the tracking network other possible applications are suggested to be included as well, one being the transmission of text messages to phones in the GSM network.

Abstract:

There is a gap of knowledge regarding relevant aspects of users’ information-seekingbehaviours. The research presented in this thesis aims at gaining a deeper knowledge about such behaviours and discussing the consequences the behaviours may have on the design practice of technical communicators when designing technical information during product development. The information needs of users, and where they go to obtain information to satisfy these needs, are considered relevant aspects. The research presented in this thesis is limited to service engineers performing maintenance in a workshop. The objective is to try to frame the information needs service engineers give evidence of in a work task and map where they go to satisfy these needs. An ethnographic research approach were selected where empirical data was collected, analysed and interpreted from a theoretical viewpoint: a synthesis of Byström and Hansen’s Conceptual Framework for Tasks in Information Studies and Systemic-Structural Theory of Activity. Seven in-house aftermarket service engineers where observed by means of participant observation while performing maintenance work tasks on machine equipment taken out of service in a maintenance workshop in Sweden.The results reveal that these service engineers gave evidence of fifty (50) different information needs, that they actively searched and selected four (4) types of sources of information to satisfy these needs, but also that service engineers seldom seek instructions. The consequence for technical communicators having the intention of designing to satisfy the cognitive information needs of individuals, is that it is a challenge to satisfy every information need. The information needs unique to any one individual and those depending on the work task context, as well as those that are specific to a work role in an organisation rather than to the machine equipment, are challenging to satisfy. This research indicates that the same type of information is used to satisfy different types of information needs. The information designed to satisfy a specific information need may thus be used to satisfy an entirely different need.

Abstract:

In this thesis I study how networks are formed and I analyse the strategies that well-connected individuals adopt in public good games on a network. In chapter one I study an artefactual field experiment in rural India which tests whether farmers can create efficient networks in a repeated link formation game, and whether group categorisation increases the frequency of in-group links and reduces network efficiency. I find that the efficiency of the networks formed in the experiment is significantly lower than the efficiency which could be achieved under selfish, rational play. When information about group membership is disclosed, in-group links are chosen more frequently, while the efficiency of network structure is not significantly affected. Using a job-referral network experiment in an urban area of Ethiopia, I investigate in chapter two whether individuals create new links with the least connected players in the network. In a first treatment, competition for job-referrals makes it in the player's interest to link with the least connected partners. In this treatment, links to the least connected players are significantly more likely than links to better connected individuals. In a second treatment, connections only affect the welfare of the new partner. Choosing the least connected player minimises inequality and maximises aggregate efficiency. This may motivate other-regarding players. In this treatment, however, links to least connected partners are not significantly more likely than links to other players. In chapter three I explore the characteristics that individuals value in the people they approach for advice. Using cross-sectional data on cocoa farmers in Ghanaian villages and a matched lottery experiment, I find an association between the difference in the aversion to risk of two farmers and the probability that one farmer is interested in the advice of the other farmer. In chapter four I study a one-shot public good game in rural India between farmers connected by a star network. Contributions by the centre of the star have a larger impact on aggregate payoffs than contributions by the spoke players. I use the strategy method to study whether the centre of the star contributes more than the average of the spokes. In selected sessions, I disclose participants' expectations about the choices of the centre of star. I find that the centre player contributes just as much as the average of the spokes, and that he is influenced by the expectations that other players hold about his decisions.

Zhang, Jackie. "Empirical essays on inferring information from options and other financial derivatives." Thesis, Lancaster University, 2017. http://eprints.lancs.ac.uk/86386/.

Full text

Abstract:

This thesis consists of three essays on inferring information from option contracts and other financial derivatives in the U.S. market as well as in the international markets. The first essay examines corporate bankruptcy probabilities inferred from option prices and credit default swaps (CDS) spreads around the 2008 financial crisis in the U.S. market. Option pricing framework is used where the risk-neutral density of the underlying asset is assumed to be a mixture of two lognormals augmented with a probability of default, to calibrate to the market option prices. The CDS model assumes a constant default probability which is solved from the non-linear equation that equates the present value of expected premium payments with the present value of expected payoffs. The essay documents that both sources provide ex-ante bankruptcy probabilities, but there is no significant evidence suggesting one predicts the other. The second essay constructs volatility indices for 15 markets around the world and examines implied volatility spillover between these markets. Volatility indices are constructed using option prices based on the new VIX methodology with modification to address its limitations. Spillover effects are then examined using vector autoregressive analysis, impulse response functions and forecast error variance decomposition. Empirical results show that the U.S. is unambiguously the dominant source of uncertainty in the world. Correlation between markets largely depends on geographical proximity. The findings support the notion of informationally efficient international stock markets, in that information transmitted from one market to another is processed within one or two days. The third essay further investigates spillover effects in variance risk premiums, which has been interpreted as the difference between the realised variance under the physical measure and the risk-neutral measure. Realized variance under the physical measure is constructed for each market using the HAR-RV model, which is able to capture long-memory characteristic of volatility. Risk-neutral expectation of future variance is approximated by a portfolio of option contracts, as calculated in the second essay. Steps are taken to address serial correlation and dependence, and variance risk premium spillovers are examined using vector autoregressive analysis, impulse response functions, and Granger Causality tests. The findings are consistent with those found in implied volatility spillovers. The U.S. market is the distributor of uncertainty in the global market. Information transmitted from one market to another is quickly digested, but it may take longer in crisis period due to greater uncertainty.

SHI, Hangyuan. "Will analysts learn from other analysts who possess superior private information." Digital Commons @ Lingnan University, 2016. https://commons.ln.edu.hk/fin_etd/15.

Abstract:

Based on a valuable testing venue in China where listed companies are required to disclose corporate site visit records of financial analyst to the public, this study examines whether analysts will learn from visiting analysts' forecasts that contain superior private information. I find that visiting forecasts tend to attract more analysts to issue forecasts in their aftermath than the prior forecasts issued by the same analysts but without conducting corporate site visit (non-visiting forecasts). The following effect is weaker when the visiting forecasts are more informative. In addition, other analysts’ forecasts following the visiting forecasts tend to move closer to the visiting forecasts than the forecasts following the non-visiting forecasts, with the effects being stronger for more informative visiting forecasts. Furthermore, followers experience a greater improvement in their forecast accuracy than the non-followers. This effect is also stronger when the visiting forecasts are more informative. Last but not the least, I find a decline in analyst forecast dispersion, an increase in common information, and an improvement in forecast accuracy in the period subsequent to the issuance of visiting analysts’ forecasts but no such effect for non-visiting forecasts. Collectively, the results suggest that analysts have incentive to learn from the forecasts that contain superior information and such learning activities tend to improve the information environment of the visiting firms.

Abstract:

Railway traffic is steadily increasing, having a negative impact on maintenance and resulting in decreased track availability, comfort, and safety. Swedish railway track maintenance mostly focuses on the actual track condition via a nationwide condition-based maintenance (CBM) strategy. For maintenance to be conducted in an appropriate way, data on the actual track condition must be accurate; furthermore, those data need to be converted into accurate information for maintenance decisions. An information assurance (IA) framework has the potential to deal with the system risks from a technical perspective. The framework is a guideline that can be implemented within CBM to understand both condition monitoring data behaviour and the information processing used to reach maintenance decisions.This research investigates ways of an information assurance (IA) framework can be implemented in the following CBM steps: data collecting, data processing and making maintenance decisions on Swedish railway. The framework can be used to understand data behaviour, information processing and the communication between information layers for decisions at organisation, infrastructure and data/information levels. The research uses both qualitative and quantitative methods to investigate critical information data, parameters, and problems and to suggest which areas need improvement. Quantitative analysis of the Swedish track geometry database reveals specific information about the behaviour of the railway data and their processing to make maintenance decisions.A case study shows how certain sections of a railway track are monitored and evaluates maintenance practices on those sections. The study finds several different types of measurements are taken using several different measurement systems. It is difficult to integrate these data for proper processing. In addition, there are problems of incomplete or irregular data; this affects the derivation of information and the use of models to understand track irregularities.Given the problems of data processing and subsequent decision making, the study suggests implementing an IA framework with CBM. The study checks the achievement of three IA principles in the existing data: authenticity, integrity and availability. The results show data have problems of authenticity and integrity, something also mentioned by the stakeholders in interviews. In particular years and on certain track sections, CM data are more than 5 percent incomplete, significantly affecting analysis. Incomplete track measurement data reach as high as 63 percent for the parameters of standard deviation (STD), longitudinal level and STD cooperation. Inaccurate measured values for alignment long wavelength within certain speed limits reach as high as 71 percent. These indicators are important for calculating track quality but are either incomplete or incorrect, negatively affecting the calculation of the Q-value and estimations of the track quality. This, in turn, negatively affects the maintenance decisions. Using information assurance will increase the system performance by permitting stakeholders to make accurate decisions.The suggested information assurance framework can discover technical problems but it needs to be improved using technologies, techniques and services to ensure complete and accurate data are available to be processed for maintenance decisions.

Abstract:

Today’s online content increases at an alarmingly rate which exceeds users’ ability to consume such content. Modern search techniques allow users to enter keyword queries to find content they wish to see. However, such techniques break down when users freely browse the internet without knowing exactly what they want. Users may have to invest an unnecessarily long time reading content to see if they are interested in it. Automatic text summarization helps relieve this problem by creating synopses that significantly reduce the text while preserving the key points. Steffen Lyngbaek created the SPORK summarization pipeline to solve the content overload in Reddit comment threads. Lyngbaek adapted the Opinosis graph model for extractive summarization and combined it with agglomerative hierarchical clustering and the Smith-Waterman algorithm to perform multi-document summarization on Reddit comments.This thesis presents WHISK as a pipeline for general multi-document text summarization based on SPORK. A generic data model in WHISK allows creating new drivers for different platforms to work with the pipeline. In addition to the existing Opinosis graph model adapted in SPORK, WHISK introduces two simplified graph models for the pipeline. The simplified models removes unnecessary restrictions inherited from Opinosis graph’s abstractive summarization origins. Performance measurements and a study with Digital Democracy compare the two new graph models against the Opinosis graph model. Additionally, the study evaluates WHISK’s ability to generate pull quotes from political discussions as summaries.

Abstract:

In the recent years, competitive video gaming, also known as eSports, has become an enormously popular phenomenon, and a part of the gaming culture. The phenomenon of eSports has created large competitive tournaments that have millions of spectators all over the world. The tournaments include huge prize pools, and eSports has lots of similarities to traditional sports. Video game live streaming is closely connected to competitive eSports and casual gaming. Nowadays it is easy for almost everyone to start streaming gameplay from home and reach people from all over the world. The streams can be, for instance, small personal streaming channels or large eSports tournament streams. Video game live streamers entertain millions of spectators and the streams have different kinds of factors that the spectators notice. The present study focused on discovering what motivates Finnish viewers to spectate eSports and other video game live streams. The study was qualitative research that included semi-structured interviews. There were 8 participants interviewed, and the interview data was analysed by using directed content analysis. The qualitative research gave in-depth information about the spectators’ motivations to watch eSports and other video game live streams. There were several reasons why the participants spectated eSports streams, such as cheering for the teams and the players, the in-game skills that the players have, desire to learn new information related to the watched game, and gathering new tips concerning the game that the participants also play. Furthermore, individual performance of the players, eSports commentators, and production quality affected the motivation to watch eSports. Moreover, it was discovered that aesthetics did not affect the participants’ eSports or other live gaming streams’ watching decision or spectating experience. The participants were motivated to watch other live gaming streams because of the streamer’s personality, newly published games, the atmosphere of the stream, the in-game skills, the gain of information and knowledge related to the game, entertainment, social actions, and escapism. Moreover, the present study provided information on why Finnish spectators spectate eSports and other video game live streams. The limitations of the research were considered, and the results could be helpful for different fields. It was discovered that there is more to be researched concerning the topic of the present study.

Abstract:

As smartphone sales increase, the demand for content for these devices alsoincreases. Service providers that want to reach out to as many users as possibleneed to create smartphone applications that satisfy people that do not fall intothe "normal user" category. People that require non-visual feedback, such asvisually impaired persons, need output in form of auditory signals. Text-tospeechsynthesis provides this functionality, giving the smartphone the abilityto convey messages in the form of speech.This thesis describes TaleTUC: Text-to-speech, a proof of concept text-to-speechsystem for the domain of bus route information. The system uses a client-serverarchitecture where the server converts text to computer-generated speech signalsand provides playable audio files either directly to the smartphone, orthrough a Java Servlet that provides functionality to tailor the output (e.g., audiocompression). Descriptions of other enhancements to bus route informationsystems, that are are not directly related to synthesized speech, have also beengiven.Three text-to-speech modules have been evaluated and to establish whetherthere is a link between intelligibility and naturalness in synthesized speech.Non-functional tests (transfer, response time, etc) have also been conductedto get an impression of whether service providers that use "cloud" technologyprovide a better service than an in-house system. There are no definitive answersto these questions, but results indicate that there might be a link (howeversmall) between intelligibility and naturalness and that an in-house systemis still preferable in the domain of bus route information.

Abstract:

I dagens affärssamhälle är utbytet av vanliga visitkort i papper enormt. Det är utan tvekan det ledande sättet för människor som träffas första gången att utbyta information i en affärsrelation. Det finns brister gällande uppföljning och hantering av vanliga visitkort och projektgruppen började då fundera på alternativ till pappersvisitkorten.

I dagens samhälle flyttas alltmer teknik till mobiltelefoner. En mobiltelefon kan idag användas till allt från att göra bankärenden till att läsa tidningen på nätet, vilket för 15 år sedan skulle låta helt orimligt. Det dyker dagligen upp nya mobilapplikationer som ska underlätta och effektivisera vardagen på något sätt och marknaden är enorm. På denna snabbt växande marknad har projektgruppen valt att ta fram ett koncept som de kallar Meetia.

Meetia är i huvudsak en mobilapplikation framtagen för att trådlöst utbyta digitala visitkort och förenkla bokning av möten genom att synka användarnas kalendrar. Applikationen har även funktioner som låter användaren enkelt och snabbt skapa nya visitkort direkt i telefonen.

Projektgruppen har även tagit fram en kompletterande hemsida till mobilapplikationen där användare har möjlighet att lagra och hantera de digitala visitkort som mottagits, för att sedan genom smarta sökfunktioner enkelt hitta de visitkort man söker.

Meetia kommer vara ett optimalt verktyg för att skapa nya kontakter då hela vägen från första kontakt till möte eller lagring av visitkort enkelt sköts med konceptet Meetia. Meetia kommer framför allt inrikta sig mot mässor där visitkort är vanligt förekommande och mängder affärskontakter skapas. För att nå ut till de stora mässorna i Sverige kommer applikationen finnas med mässfunktioner.

Abstract:

Keen competition in modern industry motivates companies to produce better products in shorter lead-time. In addition low cost is another key factor that leads commercial success of a product. In the last decade, rapid development and implementation of computer technologies have had great impact on the product development process. In the engineering area, the widely-used advanced computer-based tools enable engineers to design, analyze, simulate and test products by means of digital prototyping in the early phase of the product development process, and therefore dramatically help companies to produce better products with lower cost in shorter time. In practice, design of a complicate product is a complex work where several computer programs from different domains need to be involved. These programs normally need to combine, exchange, and share relevant product data to each other. For instance, Finite Element Analysis and Computational Fluid Dynamics may use geometrical data from a solid model and loads from a Multibody System to perform structural analysis and fluid analysis. The integration of engineering information becomes a more and more important issue in the product development process. However it is difficult to perfectly realize it due to some of the characteristics of engineering information: Heterogeneity. Programs use their own formats (domain specific or application specific) to store information and run on different operating systems and hardware. Distribution. With the development of computer network technology, a trend of engineering information systems has evolved from central systems towards distributed systems. Both data and computer programs are distributed and dynamic. This thesis deals with integration of engineering analysis information in the product development process. The research question is formulated as: How to integrate, share and exchange engineering analysis information in the product development process? The aim is to improve the ability and efficiency of integrating engineering analysis information by using modern database technology as well as other relevant technologies. A prototyping system consisting of a Mechanical Computer Aided Engineering (MCAE) system and an active mediating Database Management System (DBMS) is built. In this system the DBMS is embedded within the MCAE system, meaning that engineering applications not only gain general database capabilities such as storage management, uniform data model, query language and query processing, but also the possibility of combining data from different representations and data sources. In addition, this work presents an active database approach to enable exchange of engineering information among distributed team members in a timely manner. The distributed information is automatically synchronized between different places using database ECA rule and mediation. Only the changes are distributed to other places, which minimise the information transfer and enhance the performance. Members working at different locations can therefore interactively manipulate the same set of information at the same time.

Abstract:

This thesis investigates the effects of ICT on economic growth in Turkey and other OECD member countries. After discussing the theoretical relationships between ICT usage and economic growth, we test the positive impact of ICT revolution on economic growth econometrically. In the empirical part of the study, we perform panel data analyses by employing data sets that belong to 30 OECD member countries for 1999-2008 period as well as carrying out time series analyses for only Turkey by using data between 1980 and 2009. We find out that ICT usage and production have a positive significant effect on economic growth in OECD case. However, due to some methodological difficulties and insufficiency of critical mass regarding ICT area and complementary physical and social infrastructures in Turkey, we cannot find any significant relationship between ICT and economic growth for Turkish case.

Abstract:

In this thesis we study the information bottleneck (IB) method. This is an informationtheoretic framework which addresses the question of what are the relevant factors of arandom variable X to explain another statistically dependent random variable Y . Thesefactors are embedded into a bottleneck variable T obeying the Markov condition Y $X $ T.The contributions of the thesis are three-fold: (i) The thesis serves as a survey onthe existing connections of the information bottleneck method with rate distortion theoryand with minimal sufficient statistics, for which we also extended the known theory byproving some unproved results and deriving new connections. (ii) The thesis also servesas a survey on the information bottleneck and learning. We recover the main results onsample bounds for learning, prove them insufficient for real-world problems and show theimportance of the recently found ties between information and generalization. Moreover,we provide with a clear intuition of why the information bottleneck is a good objectivefunction for supervised learning tasks. Furthermore, we provide with a new informationtheoretic generalization bound for linear models which, to the extent of our knowledge,is the first one which does not depend on the cardinality of the random variables. (iii)Finally, the main contribution of the thesis are the results regarding the exploration of theIB curve. The IB curve is the set of points describing the solutions of the informationbottleneck optimization in terms of compression of the inputs and explainability of theoutput. We introduce the convex IB Lagrangian, an objective function which allows us toexplore the IB curve (in contrast to the previously used IB Lagrangian). Furthermore, weprove there is a bijective mapping between the Lagrange multiplier used and the obtainedpoint in the IB curve, provided the IB curve shape is known. This means one could designthe Lagrange multiplier to obtain a desired level of compression or explainability.
I den här avhandligen studerar vi the information bottleneck method. Detta är ettinformations-teoretiskt ramvärk som tar itu med vilka som är de relevanta faktorerna av enstokastisk variabel X som förklarar en annan, statistiskt beroende, stokastisk variabel Y .Dessa faktorer är inbäddade i en bottleneck variable T, vilken uppfyller Markov-villkoretY $ X $ T.Bidraget av denna avhandling är trefaldigt: (i)Avhandlingen fungerar som en undersökningav existerande kopplingar mellan information bottleneck method och rate distortiontheory samt minimal sufficient statistics. Vi utökar den kända teorin om dessa kopplingargenom att bevisa nya resultat och härleda nya kopplingar. (ii) Avhandlingen fungerar ocksåsom en undersökning av information bottleneck and learning. Vi återfår huvudresultatenom sample bounds for learning, bevisar att de är otillräckliga för moderna problem och visarvikten av de nyligen funna kopplingarna mellan information och generalisering. Vi presenterardessutom en intuition för varför the information bottleneck är en bra målfunktionför supervised learning. Dessutom så hittar vi en ny information-teoretisk generaliseringsgränsför linjära modeller som, så vitt vi vet, är den första sådana som inte beror på kardinalitetenav den stokastiska variabeln. (iii) Slutligen, avhandligens huvudsakliga bidragär resultat angående utforskningen av IB-kurvan. IB-kurvan är mängden av punkter sombeskriver lösningarna av information bottleneck optimiseringen i form av kompression avinsignalerna och förklarlighet av utsignalerna. Vi introducerar the convex IB Lagrangian,en målfunktion som låter oss utforska IB-kurvan (till skillnad från den tidigare användaIB Lagrangian). Vi bevisar dessutom att det finns en bijective mapping mellan de användalagrangemultiplikatorerna och den erhållna punkten på IB-kurvan, så vida IB-kurvansform är känd. Detta innebär att det är möjligt att konstruera lagrangemultiplikatorn så attman för en önskad nivå på kompression och förklarlighet.

Abstract:

A kiosk is a separate electronic computer terminal that allows the users to access information service. Traditional kiosks such as Automated Teller Machines (ATM) use software application with graphical user interfaces similar to normal computer system to allow users to accomplish their transaction tasks. However, this interaction mode has been proven to be difficult to use and not user-friendly for almost half of self-service users. A new type of interactive service kiosk which uses remote Video Mediated Communication (VMC) technology is to provide face-to-face talking with a customer servant to achieve the goal. Interactive VMC-based service kiosk is a tool that can be utilized in information technology field, bringing its customer convenience and close care to the virtual network. Differ from previous automated kiosk technologies which were concentrated on Human-Computer Interaction (HCI), VMC-based kiosk puts emphasis on human-to-human interface technology. It’s not only providing easier user situation for personal services but also bringing benefits for service providers due to the customized service VMC-based service kiosks offered. VMC-based kiosk service utilizes cost-saving goals accomplished meanwhile gives stimulations to achieve a new scale of perspectives and possibilities in the right direction for the company. The target for the thesis is to exploit remote car rental service using VMC-based kiosk solution and analyze its attributions relate to another three service areas, banking, travelling and reception, in order to find out in what kinds of intended future services VMC technology can be beneficial. For the purpose, this case study uses qualitative approach with scenario-based prototyping and user testing. The test results were gathered in a real use environment where nine people used the prototype and were interviewed in situ. The use situations and interviews were video recorded and transcribed for qualitative content analysis. Based on testing participants’ experience and feedbacks, the three testing cases indicated that interactive kiosk services using VMC technology in general was considered positive and well accepted. This study also clearly showed that remote VMC-based kiosk service can be successfully transferred to different service areas where similar types of negotiation-based service processes are common. By VMC-based kiosks services, customers can be offered face-to-face talk as a natural communication mode which is an overwhelmed advantage over the traditional kiosk system. Participants in study testing also felt easy and convenient in VMC-based kiosk service use by these features. Meanwhile, more concerns of how to better use of VMC-based kiosk service in other perspectives are still required in the future.

Abstract:

Bibliography: pages [83]-89.
One of the basic needs of both information systems practitioners and academics is in determining what skills and knowledge staff need in order to be able to perform adequately in their jobs (Nelson : 1991). This study was concerned with the information technology and information systems learning needs of two distinct classes of personnel; end users and information systems personnel. More specifically, it examines the perceptions that each group has of the other's particular deficiencies. It also compares the importance that each group accords to skill or knowledge in particular items for their counterparts, and how these expectations match their counterparts' own perceptions of item importance. The study was thus concerned with cross-perceptions; the perceptions that each group has of the other. This study examined these perceptions by means of the analytical survey method. The research instrument used was an adapted version of an instrument previously validated and used by Nelson (1991). The research instrument was completed by 168 employees within ten different organizations. The findings suggest that within six different areas of knowledge and skill both end user and IS personnel perceived their counterparts to be most deficient in the area of general IS knowledge; particularly in knowledge of the fit between IS and the organization, the potential uses of IS/IT within the organization, and in the use of IS for competitive advantage. In addition, both groups of personnel perceived their counterparts to be particularly deficient ii') their ability to communicate effectively. The deficiency in general IS knowledge was aggravated by the finding that both groups expect their counterparts to carry more of the responsibility for knowledge in general IS matters than their counterparts appear willing to assume. The implication of this mismatch of expectations is that it must first be resolved by clarifying the respective roles and responsibilities of both end user and IS personnel before the deficiencies themselves can be dealt with.

Abstract:

A voltage dip is a short duration reduction in voltage magnitude due to a short duration increase in current magnitude. Causes of dips are, among others, electrical faults, large motor starting, transformer energizing and failure of power-electronic converters. Voltage dips are considered as a very important power quality issue because they lead to trip or malfunction of sensitive loads especially in industrial process installations and subsequently they lead to high costs. In this thesis the overall aim is extracting additional information from large voltage dip monitoring databases. An important step to this end is providing efficient characterization methods for voltage dips. Voltage dip characterization aids by describing voltage dip events (a set of voltage waveforms with high time resolution) as a limited number of values such that this set gives as much as possible information about the dip. This thesis contributes to the voltage dip characterization development through three different methods. The first method consists of a systematic way for comparison different sets of voltage dip characteristic. With this method, both real-measured and synthetic voltage dips are applied to generic models of sensitive loads. The best set of characteristics, for representing the voltage dip, is the one best enables the reproduction of the behaviour of equipment when exposed to real-measured voltage dips. The second method compares 12 different sets of characteristics for describing three-phase single-events.. The method determines the most efficient and feasible way that gives more realistic characteristics as well as comparable with existing standard methods. The proposed set of characteristics has been proposed for inclusion in international standard documents. The third method enables the extraction of dip characteristics based on machine learning approaches. It is applicable for characterization of multi-stage voltage dips in particular and for single-stage (normal) voltage dips as well. The proposed method uses the space-phasor model of three-phase voltages as an input data for k-means clustering algorithm. Then the calculated data are modeled as a general form of an ellipse by exploiting logistic regression algorithm. Finally the optimized obtained ellipse parameters are applied to calculate single-segment characteristics for each individual stage of a multi-stage voltage dip. Further, all proposed methods are implemented in an Matlab environment and validated by applying them to a large number of real-measured voltage dips in actual HV and MV power networks and some suitable synthetic voltage dips.

Abstract:

This dissertation is organized in three separate chapters. A common thread intertwined in the three of them is the role of informational flows at influencing individual´s choice. Chapter 1 provides novel empirical evidence on the role of imperfect information about price schedules on determining consumer's demand choice for the residential gas market using a natural experiment and consumer microdata from the metropolitan region of Buenos Aires, Argentina. Based on the results a large field experiment carried out in a municipality of Argentina, Chapter 2 presents new empirical results showing that taxpayers are relatively insensitive to information on the prevailing level of tax evasion and the supply and quality of local public goods, whereas raising the salience of fines and other related penalties may have a large bearing on tax compliance. Relatedly, Chapter 3 presents novel evidence, also based on a field experiment conducted in another Argentine municipality, suggesting that informational treatments influence taxpayers' beliefs about the risk of detection and the salience of penalties in the case of non-compliance, and hence, their compliance behaviour with respect to the tax code.

Abstract:

The importance of conducting efficient product development is growing steadily as traditional market boundaries diminish and are replaced by global market conditions. Digital product development builds on the foundation that digital mock-ups replace physical mock-ups, and this has the potential for strongly improving the efficiency of the product development process. This is a rather drastic change compared to the conventional way of conducting product development, and it cannot be implemented overnight. It requires the extended enterprise to rely on geometry based product models. Business excellence is therefore partially synonymous with managing these models and making them available, and relevant, to different activities throughout the product development process. This thesis deals with the establishment of two key expressions, Geometry Management Process and Geometry Based Product Information. The objective is to improve the utilisation of Geometry Based Product Information by supporting the product development process with adequate methods, tools and processes for managing this type of information. This objective is partly realised by the elimination of rework in the downstream activities of traditional design departments. There are numerous influencing factors and the research approach has been to collect these factors into four separate but correlating domains. The consistency in the approach stems from the fact that all research work is conducted with a geometrical perspective on all types of activity, requirement and process. The methodology is elaborated through participation and surveys of real cases in ongoing projects and activities when developing heavy-duty trucks.

Full text

Abstract:

Pri.or to 1990, and the advent of deregulation in the UK, the Electricity Supply Industry (ESI) was a state-owned, vertically integrated monopoly. For the first time the way was opened for the introduction of competitiveness into the many and varied aspects ofthe market. This brought with it diversity and additional requirements for customer and engineering services. This new business-driven, customer-orientated environment led to the re~assessment of the utility's customer communication systems. In order to take full advantage of this new environment, an integrated communications and information systems infrastructure is required. This thesis addresses the design and development of an efficient and reliable communications system for the collection and distribution of data within the ESI. Although the communications architecture proposed focuses on meeting the requirements of a specific Regional Electricity Company, SWEB, it is generic and hence may be used in any electric utility. This architecture, based on an open systems approach, provides bearer services to existing and emerging engineering and business applications. The open system aspect permits the deferred design of system components, thereby providing maximum system flexibility and simplicity. An overview ofthe operational systems in the ESI as they existed in 1997 is given. This review considers the power engineering and distribution networks, metering and tariffs, together with SWEB's specific IT and data communication systems. There then follows a review ofthe business and technical environments in the industry, in terms ofthe potential benefits of value-added services and the emerging applications, together with a brief analysis of the post-privatisation growth ofthe telecommunications industry in the UK. A review was carried out on the media used for different communication services involving Power Line Carrier technology (PLC), Telephony, Fibre Optic Cable (FOC), Twisted Pair and Coaxial cable. These media are examined as to their suitability for data communications for the electric utility industry. Various modulation techniques including AM, FM and Spread Spectrum systems were investigated with respect to their transmission characteristics, and a comparison made ofthe modulation techniques used in PLC systems. The 1990s saw considerable interest in utility communications resulting in many trials being carried out throughout the world. A number ofthese are reviewed in this thesis in support of the proposed architecture. The cardinal factor in the design and development of any modern communication system is the compliance with internationally agreed standards and recommendations. The Open Systems Interconnection model is introduced. together with the standards, protocols and profiles particularly relevant to utility communications. The Utility Communications Architecture (UCA) profile, developed by the Electric Power Research Institute (EPRI) is also introduced. The programme ofwork outlined in this thesis was driven by two objectives. The first of these was the aim of utilising the considerable copper infrastructure in the ESI distribution systems for communication purposes. The second was to investigate the feasibility of the provision ofvalue-added services. The generic architecture presented here, based on powerline carrier and other media technology, clearly satisfies the first ofthe above objectives. However PLC inherently lacks the bandwidth for some ofthe value-added services considered, and this may lead slow data transfer rates for certain applications such as downloading large text, image and audio files from internet websites.The second objective was pragmatically modified to address the problems of Remote Metre Reading. To this end a protocol is proposed which requires a minimum data rate transfer thereby conserving network bandwidth.

Abstract:

As the usage of both BIM (Building Information Modelling) and 3D-GIS (Three-Dimensional Geographic Information Systems) has increased within the field of urban development and construction, so has the interest in connecting these two tools. One possibility of integration is the potential of visualising BIM models together with other spatial data in 3D. Another is to be able to perform spatial 3D analyses on the models. Both of these can be achieved through use of GIS software. This study explores how integration of BIM and GIS could look. The goal was to perform typical GIS analyses in 3D on BIM models. Previous research points towards some success within the field through use of the indicated standard format for each tool – IFC (Industry Foundation Classes) for BIM and CityGML (City Geographic Markup Language) for GIS. Transformation between the formats took place through use of the BIM software Revit, the transformation tool FME and the GIS software ArcGIS. A couple of reviewed applications of GIS analyses were chosen for testing on the converted models – indoor network analysis, visibility analysis and spatial analysis for 3D buildings. The input data in the study was several BIM models, both models created for real-life usage and others that only function as sample data within the different software. From the results of the practical work it can be concluded that a simple, automated and full-scale integration does not seem to be within reach quite yet. Most transformations between IFC and CityGML failed to some extent, especially the more detailed and complex ones. In some test cases, the file could not be imported into ArcGIS and in others geometries were missing or existing even though they should not. There were also examples where geometries had been moved during the process. As a consequence of these problems, most analyses failed or did not give meaningful results. A few of the original analyses did give positive results. Combining (flawed) CityGML models with other spatial data for visualisation purposes worked rather well. Both the shadow volume and sightline analyses did also get reasonable results which indicates that there might be a future for those applications. The obstacles for a full-scale integration identified during the work were divided into four different categories. The first is BIM usage and routines where created models need to be of high quality if the final results are to be correct. The second are problems concerning the level of detail, especially the lack of common definitions for the amount of details and information. The third category concerns the connection between local and global coordinate systems where a solution in form of updates to IFC might already be in place. The fourth, and largest, category contains those surrounding the different formats and software used. Here, focus should lie on the transformation between IFC and CityGML. There are plenty of possible, future, work concerning these different problems. There is also potential in developing own tools for integration or performing different analyses than those chosen for this thesis.
I takt med den ökade användningen av både BIM och 3D-GIS inom samhällsbyggnadsprocessen har även intresset för att sammanföra de två verktygen blivit större. En möjlighet med integration är potentialen att visualisera BIM-modeller tillsammans med andra geografiska data i 3D. En annan är att kunna genomföra rumsliga 3D-analyser på modellerna. Båda dessa går att utföra med hjälp av GIS-programvara. Denna studie utforskar hur en integration mellan BIM och GIS kan se ut. Målet är att genomföra typiska GIS-analyser i 3D på BIM-modeller. Tidigare forskning pekar mot vissa framgångar inom området genom att arbeta med det utpekade standardformatet för respektive verktyg – IFC för BIM och CityGML för GIS. Transformation mellan formaten skedde med hjälp av programvarorna Revit, FME och ArcGIS. Ett par framhållna tillämpningar av GIS-analyser valdes ut för tester på de konverterade modellerna – nätverksanalyser inomhus, siktanalyser och rumsliga analyser för 3D-byggnader. Som indata användes flera olika BIM-modeller, både sådana som tillverkats för faktisk användning och modeller som skapats för att användas som exempeldata inom programvarorna. Utifrån resultaten från det praktiska arbetet kan konstateras att en enkel, automatiserad och fullskalig integration mellan verktygen verkar ligga en bit in i framtiden. De flesta transformationerna mellan IFC och CityGML misslyckades i någon aspekt, speciellt de mer detaljerade och komplexa. I vissa testfall kunde filen inte importeras i ArcGIS, i andra saknas eller existerar oväntade geometrier även om importen lyckats. Det finns också exempel där geometrier förflyttats. Som en konsekvens av dessa problem kunde de flesta 3D-analyser inte genomföras alls eller lyckades inte ge betydelsefulla resultat. Ett fåtal av de ursprungliga analyserna gav dock positiv utdelning. Att kombinera (felaktiga) CityGML-modeller med annan rumslig data fungerade förhållandevis väl ur ett visualiseringssyfte. Både skuggvolymsanalysen och framtagandet av siktlinjer från byggnaderna gav någorlunda korrekta resultat vilket indikerar att det kan finnas en framtid gällande de tillämpningarna. Hindren för en fullskalig integration som identifierades genom arbetet delades upp i fyra olika kategorier. Den första är BIM-användning där hög kvalitet på de skapade modellerna är viktigt för korrekta slutresultat. Den andra är detaljeringsgraden där avsaknaden av gemensamma definitioner för detaljeringsgraderna ställer till problem. Den tredje kategorin är koordinat- och referenssystem där en lösning på kopplingen mellan lokala och globala system redan kan finnas på plats i en av de senare utgåvorna av IFC-formatet. Den sista och största kategorin är problematiken kring just format och programvaror där mer arbete på översättningen mellan IFC och CityGML kommer att krävas. I framtiden finns det gott om arbete att göra med dessa olika problem. Det finns också potential att utveckla egna verktyg för integrationen eller att ägna sig åt att göra andra analyser än de som valdes ut i den här studien.

Abstract:

Critical infrastructures are the lifelines of modern societies. The Communication and Information Technology Infrastructure (CITI) provides the basic mechanisms for sharing control and decision-making information among different critical infrastructures. Failures in CITI, either due to an accident or malicious action can propagate to other infrastructures and degrade or disrupt their functionality. Conversely, failures in other infrastructures can also propagate to CITI and hence disrupt the operation of many of the interconnected systems. For reliable and consistent operation of critical infrastructure networks, it is important to have tools and techniques to model and simulate CITI related interdependencies. This research is focusing on developing such methods and tools for CITI interdependency modelling and simulation. Our approach is based on system engineering techniques, where critical infrastructures are viewed as a system of systems. Interdependencies between different system components are captured using precise mathematical functions. As such, our approach goes beyond the limitations of agent-based modelling and simulation paradigms, where interdependencies are considered an emergent behavior. In this research, we have used predictive modelling techniques commonly used in power systems, data communication networks and information systems. The approach is based on results from real CITI interdependency related data. In our model, we used these data to identify the origin of different types of CITI failure and their impacts on critical infrastructures. Following that, we developed techniques to estimate interdependencies between CITI and other critical infrastructures. Finally, we developed techniques to simulate CITI interdependencies in a critical infrastructures simulator. The simulation results were validated against real-life failure cases. Our approach gives a comprehensive solution to CITI interdependency modelling and simulation problems and hence is an important step in the critical infrastructure related research. Even though our techniques are developed for CITI interdependency, they will be useful for other critical infrastructure networks as well.

Full text

Abstract:

The effects of expertise, such as better recognition of own-race than other-race faces, have been attributed either to poor encoding of configural information (the dual-mode theory) or to representation of faces on dimensions attuned to own-race faces and, hence, inappropriate for coding of other-race faces (the ABC model). Neither framework alone has been able to account for the variety of past results. It is proposed that a composite account derived from the dual-mode theory and the ABC model may offer a more complete explanation of the effects of race. To evaluate the composite account, six experiments using perceptual paradigms were carried out. The structure of face space and the effects of expertise on configural processing were assessed in a dissimilarity perception task (Experiment 1). Caucasian and Chinese participants judged dissimilarity of own-race and other-race faces with various configural distortions relative to their unaltered versions. As predicted by the composite account, face spaces derived from the dissimilarity ratings for own-race and other-race faces were comparable. Consistent with the premise that expertise affects configural coding, Caucasian participants exhibited greater sensitivity to configural changes of own-race than other-race faces. The effects of expertise on configural encoding were further examined in a bizarreness perception paradigm (Experiments 2-4). Caucasian participants rated bizarreness of unaltered and distorted faces rotated from upright to inverted in 15� increments. The distortions involved either simple component alterations (i.e., whitened pupils and blackened teeth), global configural changes (i.e., inverted eyes and mouth), or more local configural transformations (e.g., moving the eyes closer together and upwards, and shifting the mouth down). Similar bizarreness ratings for all faces with component distortions confirmed that expertise does not affect processing of simple component information. Differences in the perceived bizarreness of own-race and other-race faces in the unaltered and global configural distortion conditions corroborated the hypothesis that expertise influences holistic configural encoding. Variations in the perceived bizarreness of faces with more local configural changes, however, indicated that expertise might also affect local configural coding. The effects of expertise on local configural processing were further examined in a discrimination paradigm (Experiments 5 and 6). Participants made same-different decisions with upright and inverted face pairs comprising either two identical faces (same trials) or unaltered and distorted versions of the same face (different trials). To distinguish between holistic and local processing of configural information, partial faces were created in addition to whole faces. Higher accuracy for own-race than other-race faces at both upright and inverted orientations in both whole and partial face conditions substantiated the argument that expertise modulates local configural encoding. Altogether, the present investigation offers direct evidence for the composite account of the effects of race. As ventured by the composite account, the own-race face bias in face perception was shown to be due to variations in configural processing. In addition, the reported experiments support the argument that configural information can be encoded both locally and holistically.

Abstract:

Memory binding is a cognitive process that enables complex objects to be stored or retrieved coherently during perception, learning, or action. Binding functions are aimed at reducing the misattribution of the features of objects in crowded and changing sensory contexts, ensuring accurate representation in visual working memory. Binding is a relatively new concept in working memory research. However, as an integrative function it provides a rich context in which to investigate the mechanisms underlying memory deterioration. In this PhD project, a range of experimental temporary binding paradigms were used to investigate whether some of the memory impairments observed in patients with Alzheimer’s Disease could be accounted for by deficits in this memory function. A set of neuropsychological tasks were used to investigate binding operations across memory domains (i.e., verbal and nonverbal), sensory modalities (i.e., visual and auditory), types of information (e.g., objects and colours), and retrieval processes (i.e., recognition and recall) in healthy individuals, Alzheimer’s Disease patients and other clinical populations. The results suggest that the efficiency of short-term memory to store bound complex events depends on the nature of the information presented (e.g., type of information bound into objects) (Chapter 2). Short-term memory seems to be equipped with relatively separate mechanisms to store integrated objects and individual features (Chapter 4). It was also observed that the binding properties of short-term memory apply to healthy young and older people, and are functions which are preserved in the elderly (Chapter 3). In two additional experimental chapters (5 and 6) the preserved binding abilities of older people were compared with temporary binding in Alzheimer’s Disease. The latter group showed a very large impairment in binding that was distinct from their impairments in memory for individual features. These findings suggest that memory binding tasks could reliably separate the cognitive changes in normal ageing from those linked with Alzheimer’ Disease. Moreover, the results of Chapter 7 suggested that memory binding tasks may detect memory changes in people that will develop Alzheimer’ Disease (i.e., asymptomatic carriers of the gene defect E280A of the Preseniline-1 gene) almost 10 years before the average age of onset. These results are relevant to our understanding of short-term memory and to the memory models currently available. Finally, it is suggested that the constructs of memory binding may increase the sensitivity of current assessment procedures for people at risk of developing Alzheimer’s Disease.

Abstract:

We define information in living systems as a reproducible and versatile catalyst. We argue that a key dimension for the evolution of information and the understanding of life is informactivity, a measure of the contribution to fitness of information. We then move to a clarification of information processing characteristics. We organise these characteristics into three sets related to content-holding, interfacing and transferring processes. We argue that evolution can play with mobility and interoperability of information which are aggregates of first order characteristics. We also argue that a better understanding of how these processes evolve will lead to a better and more exhaustive perception of major transitions in evolution. We then exemplify how in certain “procooperative” environments interoperability can co-evolve with cooperative behaviours. We argue that a Red Queen process can affect interoperability of information related to public good production. In specific conditions this may allow to maintain cooperation in a population. At last, we discuss how science and education in human culture can be understood within the theoretical framework that has been proposed
Nous définissons l'information dans les systèmes vivants comme un catalyseur reproductible et versatile. Nous considérons qu'une dimension clef pour la compréhension des systèmes vivants et de leur évolution est l'informactivité, une mesure de la contribution d'une information à la valeur sélective. Nous procédons ensuite à une clarification des caractéristiques des procédures de gestion d'information. Nous regroupons ces caractéristiques en trois ensembles qui sont relatifs au portage du contenu, aux interfaces et aux transferts. Nous expliquons comment l'évolution affecte en particulier la mobilité et l'interopérabilité des informations, ces dernières étant des propriétés relatives à des agrégats de caractéristiques du premier ordre. Nous faisons l'hypothèse qu'une meilleure compréhension de l'évolution des processus de gestion de l'information permettra d'analyser de façon plus étendue et plus précise les transitions évolutives majeures. Nous donnons ensuite l'exemple de la co-évolution de la coopération et de l'interopérabilité dans des environnements que nous qualifions de « pro-coopératifs ». Nous expliquons comment la coopération peut être maintenue par une Reine Rouge évolutive affectant le niveau d'interopérabilité d'informations relatives à la production de biens publics. Enfin nous proposons une application de ce cadre théorique à la compréhension du fonctionnement et de l'évolution de l'éducation et de la science dans la société humaine

Abstract:

Automotive systems are being developed to increase positive driver experiences and traffic safety. As these new technologies are being adapted into the automotive environment, i.e. safety systems and multimedia applications, are the drivers additionally taking with them nomad devices, i.e. mobile phones, media players, GPS devices, etc., into this environment making it more and more complex. This complexity does not help the driver and in some cases distracts the driver too. The number of information sources has escalated to new heights and this trend does not seem to be slowing down. To be able to keep up with the advances in information technology, which also includes advances in display technology, automobile manufacturers are seeking for new and/or different ways to attract potential customers without bending the traffic safety. In this thesis this phenomena is looked upon by studying how drivers could use the information presented to them in the automobile. What do drivers perceive as important information, how should it be presented, and where? To obtain this several studies were conducted to gain a more complete picture of a driver's perception, behavior, and preferences. First, a questionnaire was administered to three different culture groups; China (167), Sweden (142), and United States of America (89) to learn how they perceive the information's importance and placement. The results showed that the drivers preferred the locations used in their own automobiles, but could think of using the HUD for more advanced driving helps. Based upon those responses a second study was conducted in a fixed-based high fidelity driving simulator. Forty participants drove a baseline and a experiment block (ca 20 min each) in which they where given either 10 warnings or 10 messages from four locations found in automobiles; the Head-Up Display (HUD), Head Down Display (HDD), Infotainment Display (IF), and Center-Stack Display (CS). The measurements were time to respond, time to notice, glance time, fixation time, number of fixations, and their driving performance via lane deviation and average speed during in each particular situation. All the drivers preferred information being presented in the HUD and the data showed that their performance was just as good as in the IF location and significantly better than in the CS and HDD locations. Redundant information in the HUD and HDD were not preferred and the participants the HUD exclusively. These results gave support to test HUD in traffic and in the drivers own vehicles. Therefore 30 drivers were recruited to test a HUD during three around the clock days, which showed the automobiles actual speed in their own automobiles on the windscreen. The on-road test showed that HUD was significantly preferred over the HDD for speed information. The majority of the drivers also wanted important warnings to be made available there along with directional helps for navigation. In conclusion the HUD was seen as the "next step" in automobile development. To reduce time away from road, increase traffic awareness, and to "lift" necessary information from more difficult to notice, and attend to, locations to the traffic scene the HUD could be the solution to enhance traffic safety, while speedometer and warning areas could be "freed up" and used for other functions and systems, leaving the locations furthest away for non-critical information.

Abstract:

This study is concerned with the way in which discourses of the Other are deployed in the media's narrative constructions of national imaginary. Operating on the assumption that news provides techniques and devices which enable the nation and its Other to be narrated and imagined, the analysis focuses on the structures and processes by which Japan is constructed in the news stories in some Australian and Chinese printed media. The analysis finds that othering is a dynamic and complex process engaged in by both the East and the West, for purposes of both cultural domination and cultural negotiation, and to serve both external and domestic political ends. The study shows that what seems to be an essential distinction between the Orient, or the East, and the Occident, or the West, in the discourses of the Other is constantly shifting, fluid and context-specific. The investigation points to the need of forsaking a framework of understanding media and identity which is based on a truth vs propaganda, or information vs entertainment dichotomy, and adopting an approach that takes into account the particularities of the cultural practices of each media system

Abstract:

When a signal is decomposed into frequency bands, demodulated into modulator and carrier pairs, and portrayed in a carrier frequency-versus modulator frequency domain, significant information may be automatically observed about the signal. We refer to this domain as the modulation spectral domain. The modulation spectrum is referred to as a windowed Fourier transform across time that produces an acoustic frequency versus modulation frequency representation of a signal. Previously, frameworks incorporating the discrete short-time modulation transform (DSTMT) and modulation spectrum have been designed mostly for filtering of speech signals. This modulation spectral domain is rarely, if ever, discussed in typical signal processing courses today, and we believe its current associated tools and applications are somewhat limited. We seek to revisit this domain to uncover more intuition, develop new concepts to extend its capabilities, and increase its applications, especially in the area of music data mining. A recent interest has risen in using modulation spectral features, which are features in the modulation spectral domain, for music data mining. The field of music data mining, also known as music information retrieval (MIR), has been rapidly developing over the past decade or so. One reason for this development is the aim to develop frameworks leveraging the particular characteristics of music signals instead of simply copying methods previously applied to its speech-centered predecessors, such as speech recognition, speech synthesis, and speaker identification. This research seeks to broaden the perspective and use of an existing modulation filterbank framework by exploiting modulation features well suited for music signals. The objective of this thesis is to develop a framework for extracting modulation spectral features from music and other signals. The purpose of extracting features from these signals is to perform data mining tasks, such as unsupervised source identification, unsupervised source separation, and audio synthesis. More specifically, this research emphasizes the following: the usefulness of the DSTMT and the modulation spectrum for music data mining tasks; a new approach to unsupervised source identification using modulation spectral features; a new approach to unsupervised source separation; a newly introduced analysis of FM features in an AM-dominated modulation spectra; and other applications.

Abstract:

Denna uppsats presenterar en kvalitativ undersökning som gjorts i syfte att visa vilka likheter och olikheter det finns på synen på bevarande av arkivinformation som bevis inom arkiv- och informationsvetenskap jämfört med e-Discovery. Målet med undersökningen var också att öka förståelsen för synen på vilka krav som ställs på bevarad information för att den ska kunna användas som bevis, både på kort och lång sikt. De data som samlats in består främst av akademiska artiklar och andra texter, där en kvalitativ innehållsanalys har använts för att tolka den latenta informationen i dessa texter. Den teori som använts som grund för denna analys är Records Continuum-teorin, där bevisaxeln har varit till störst användning. Resultatet visar att synen på bevarande av arkivinformation som bevis skiljer sig en del inom arkiv- och informationsvetenskapen och e-Discovery, men vissa likheter finns också. Det visar vidare också att tidsspannet som information anses värdefull att bevara skiljer sig mellan de två och att detta beror på att man fokuserar på olika saker. Detta påverkar slutligen vilka sammanhang information bevaras i, och vilket bevisvärde den får.
This essay presents a qualitative research undertaken with the purpose of showing similarities and differences in the views on preservation of records as evidence within archival and information sciences compared to the ones within e-Discovery. Further, the goal with the research was also to increase the understanding for how the demands are viewed, that are put on preserved information for it to be usable as evidence, both short and long term. The data which have been gathered are mainly academic articles and other texts, where a qualitative content analysis has been used to interpret the latent information in these texts. The theory used to conduct this analysis is the Records Continuum theory, where the Evidentiality axle has been of the most use. The result shows that the views on preservation pf records as evidence differ between the archival sciences and e-Discovery, but that there are also similarities. It also shows that the period of time in which information is considered worth preserving differs between the two and that this is due to the fact that their areas of focus are different. This ultimately affects in what contexts information is preserved, and also its value as evidence.

Abstract:

The use of dependencies have been increasing in popularity over the past decade, especially as package managers such as JavaScript's npm has made getting these packages a simple command to run. However, while incidents such as the left-pad incident has increased awareness of how vulnerable relying on these packages are, there is still some work to be done when it comes to getting developers to take the extra research step to determine if a package is up to standards. Finding metrics of different packages and comparing them is always a difficult and time consuming task, especially since potential vulnerabilities are not the only metric to consider. For example, considering how popular and how actively maintained the package is also just as important. Therefore, we propose a visualization tool called DependencyVis that is specific to JavaScript projects and npm packages as a solution by analyzing a project's dependencies in order to help developers by looking up the many basic metrics that can address a dependency's popularity, activeness, and vulnerabilities such as the number of GitHub stars, forks, and issues as well as security advisory information from npm audit. This thesis then proposes many use cases for DependencyVis to help users compare dependencies by displaying the dependencies in a graph with metrics represented by aspects such as node color or node size.

Abstract:

Information Science is an interdisciplinary field that interacts with other disciplines through its intellectual borders. While there is much research into the interdisciplinary nature of Information Science, little research exists that identifies the nature, extent, and quality of these extra-disciplinary interactions. The purpose of the present study is to provide in-depth analyses of the implicit and explicit contexts of citations as a means of exploring the nature of citations that Information Science literature receives from the literature published in other disciplines. This sort of analysis reveals the level of citation impact that Information Science literature contributes to the advancement of knowledge in other disciplines.The present research is led by one main research question: What is the "nature" of citations that highly cited papers appearing in the Journal of the American Society for Information Science and Technology (JASIST) receive from citing papers published outside the Information Science field? The present study uses two citation contextual measures to define and determine the nature of citations: citation functions and citation textual properties, including citation location, citation frequency, and co-citation frequency. Citation context analysis was selected as the research method. Highly cited JASIST papers were assumed to represent Information Science literature for the purpose of the present research. Citation contexts of highly cited papers were used as a "radioactive tracer" to investigate the contributions of Information Science literature to other disciplines. A detailed citation classification scheme was constructed to identify functions and roles of citations. Results of implicit and explicit analyses of citation contexts showed that citations convey different meanings, serve different purposes, and all citation functions are not of equal significance. It was also demonstrated that the nature of citations may vary across a wide spectrum of different functions and roles, with different impact levels on the theme of citing papers. Citation functions showed a significant association with all three textual properties, including citation location, frequency of citation occasion and co-citation frequency. The high rate of citations within Information Science journals (74.7 percent) indicates that highly cited JASIST papers are cited extensively in other Information Science journals. This rate drops to 25.3 percent for publications outside of Information Science. An investigation of the nature of the contributions of highly cited papers to other disciplines shows that the vast majority of citations (80 percent) convey "reviewed" or "perfunctory" functions. Furthermore, for 51 percent of citing papers, the impact level of highly cited JASIST papers was ranked "low" or "relatively low". The disciplines to which Information Science mainly contributes include Computer Science, Psychology, Education, Business, and Communication. The present research concludes that Information Science literature is yet to have a major theoretical or methodological impact on other disciplines. At the conceptual level, the Citation Pyramid Model was suggested to provide a common ground for both normative and constructivist theories. This model shows that both theories can be intertwined and act complementarily rather than as mutually exclusive theories to explain such an internal and complex phenomenon as citation motivations.
La science de l'information est un domaine interdisciplinaire qui interagit avec d'autres à travers ses frontières intellectuelles. Bien qu'il y ait beaucoup de recherches sur la nature interdisciplinaire des sciences de l'information, peu de recherches identifient la nature, l'étendue et la qualité de ces interactions extradisciplinaires. Le but de l'étude est de fournir une analyse approfondie des contextes implicites et explicites de citations pour explorer la nature de citations que la littérature des sciences de l'information reçoit d'autres disciplines. Cette analyse approfondie révèle le niveau de l'impact des citations auquel la littérature des sciences de l'information contribue pour l'avancement des connaissances dans d'autres disciplines. La présente recherche a été menée par une principale question de recherche: Quelle est la «nature» que les citations des articles les plus cités figurant dans le Journal of the American Society for Information Science and Technology(JASIST) reçoit lorsque les articles qui sont cités sont publiés dans d'autres disciplines? La présente étude utilise deux mesures contextuelles de citations pour définir et déterminer la nature des citations: les fonctions de citation et les propriétés textuelles de citation, y compris l'emplacement des citations, la fréquence de citation et la fréquence de co-citation. L'analyse du contexte des citations a été choisie comme méthode de recherche. Les articles les plus cités de JASIST étaient supposés représenter la littérature des sciences de l'information dans le but de la présente recherche. Les contextes de citation des articles les plus cités ont été utilisés comme «traceur radioactif» pour enquêter sur les contributions de la littérature des sciences de l'information à d'autres disciplines. Un système de classification de citation détaillé a été construit pour identifier les fonctions et les rôles des citations.Les résultats des analyses implicites et explicites des contextes de citation montrent que les citations véhiculent des significations différentes, servent à des fins différentes, et toutes les fonctions de citations ne sont pas d'égale importance. Il a également été démontré que la nature des citations peut varier dans un large éventail de fonctions et de rôles différents, avec différents niveaux d'impact sur le thème des articles cités. Les fonctions de citations ont montré une corrélation significative avec les trois propriétés textuelles, y compris l'emplacement de citation, la fréquence de citation et la fréquence d'occasion de citation et la fréquence de co-citation. Le taux élevé de citations dans des revues sciences de l'information (74,7 pour cent) indique que les articles les plus cités de JASIST sont cités abondamment dans d'autres revues des sciences de l'information. Ce taux tombe à 25,3 pour cent pour les publications en dehors des sciences de l'information. Une enquête sur la nature de la contribution des articles les plus cités à d'autres disciplines montre que la grande majorité des citations (80 pour cent) véhiculent des fonctions «examinées» ou «superficielles». En outre, pour 51 pour cent des articles cités, le niveau d'impact des articles les plus cités de JASIST a été classé «faible» ou «relativement faible». Les disciplines auxquelles les sciences de l'information contribuent comprennent principalement l'informatique, la psychologie, l'éducation, les affaires et la communication. La présente étude conclut que la littérature des sciences de l'information reste proche d'avoir un impact majeur théorique ou méthodologique sur d'autres disciplines. Sur le plan conceptuel, le modèle «Citation Pyramid» a été suggéré afin de fournir une base commune pour à la fois les théories normatives et constructivistes. Il montre que les deux théories peuvent être imbriqués et agir en complémentarité au lieu de théories qui s'excluent mutuellement pour expliquer un tel phénomène interne et complexe que les motivations de citation.

Abstract:

The importance of innovation networks in health information system transformation has been recognised in research. It has been agreed that better-organised innovation networks can be related to better results of patient information system transformation. However, current research do not know much about how those innovation networks are organised, especially the structure of teamwork and information exchange in innovation networks. Thus, this study aims to improve the understanding about how innovation networks are organised and the influences on innovation results. Based on innovation network theory, this study develops and integrates three aspects, network dynamics, network structure and network influence, to explore innovation networks in patient information system transformation. Network dynamics represent complex interactions among people in the process of innovation; network structures show each person's roles and connections in the network; and and network influences link network structures to patient information system upgrade outcomes. Following this theoretical framework, this study answers three research questions: 1) what are the network patterns appearing frequently in network dynamics? 2) What are the patterns of the network structures? 3) To what extent innovation networks can influence the innovation outcomes? The data are collected form four patient record transformation projects in China. This study adopts network analysis method to demonstrate the fabrics of collaborations among the participants in innovation and quantify the regular network patterns and structures. Then, this study uses network regression modelling to explore the relations between innovation networks and innovation outcomes. This study contributes to innovation network research and by presenting 1) the patterns of innovation network dynamics. It demonstrates various patterns of innovation networks in each innovation stages; 2) the innovation network structures. This study identifies five types of brokers and two structures co-existing in the innovation network; 3) network influence. This study suggests that network structures significantly influence the outcomes.

Abstract:

Purebred Beefmaster steers (n = 160) from five owners were fed at a commercial feedlot in South Texas beginning in November of 2004; 68 steers possessed pedigree information. Beginning in mid-November, steers were individually weighed and evaluated for ultrasound body composition at 56-d intervals by a certified technician. Feeder calf frame (FRM) and muscle (MUS) scores were assigned at initial ultrasound evaluation. Steers were fed and marketed through a lean-based, branded beef program and were harvested in two groups in May and June of 2005 at a commercial beef plant. Analyses were conducted to investigate the ability to predict carcass traits from the different sources of information available on these cattle. Evaluation of carcass traits were investigated using four sets of independent variables referred to as sources A, B, C, or D and ultrasound scan session (1 Â 4). An analysis included initial weight at first scan session (IWT), FRM and MUS as independent variables through GLM procedures. B analyses utilized ultrasound measures of the longissimus area, intramuscular fat, fat thickness, rump fat, and gluteus medius depth along with IWT as independent variables. Multiple regression was performed on each carcass trait using IWT and ultrasound traits at each scan session. MallowÂs CP was used to select a model that best described each carcass trait. C analyses (GLM) utilized variables from A and B analyses combined plus ranch. D analyses (GLM) included variables from C analyses plus sire nested within ranch. Respective R-square values (scan 1 Â 4) for marbling score were .02, .04, .05, and .10 using A information, .14, .17, .42, and .54, using B information, .35, .35, .47, and .55 using C information, and .56, .59, .65, and .76 using D information. R-square values ranged from .34 to .86 for carcass weight, .11 to .77 for fat thickness, .06 to .82 for ribeye area, and .10 to .81 for yield grade. Ultrasound data obtained closer to harvest and increasing amount of data related to genetic and management background showed increased R-square values, but may be best utilized in conjunction with one another to predict carcass traits and final carcass value.

Abstract:

The central aim of the current thesis was to examine how facial expression and racial identity information affect face processing involving different races, and this was addressed by studying several types of face processing tasks including face recognition, emotion perception/recognition, face perception and attention to faces. In particular, the effect of facial expression on the differential processing of own and other race faces (the so-called the own-race bias) was examined from two perspectives, examining the effect both at the level of perceptual expertise favouring the processing of own-race faces and in-group bias influencing face processing in terms of a self-enhancing dimension. Results from the face recognition study indicated a possible similarity between familiar/unfamiliar and own-race/other-race face processing. Studies on facial expression perception and memory showed that there was no indication of in-group bias in face perception and memory, although a common finding throughout was that different race faces were often associated with different types of facial expressions. The most consistent finding across all studies was that the effect of the own-race bias was more evident amongst European participants. Finally, results from the face attention study showed that there were no signs of preferential visual attention to own-race faces. The results from the current research provided further evidence to the growing body of knowledge regarding the effects of the own-race bias. Based on this knowledge, for future studies it is suggested that a better understanding of the mechanisms underlying the own-race bias would help advance this interesting and ever-evolving area of research further.

Full text

Abstract:

This thesis investigates the role of Information and Communication Technologies (ICT) and other intermediate goods in multi-sector growth models that aim to account for recent growth experiences of the United Kingdom and the United States. Chapter 2 examines how ICT drive growth in an economy with three sectors: ICT-producing, ICT-using and non-ICT-using. The benefits from ICT come from the falling prices of the ICT-using sector good, which is used for the production of intermediates. Their falling prices provide incentives for investment in sectors that use them as intermediate inputs, so the non-ICT-using sector experiences sustained growth driven by capital accumulation. Sectorial rates of growth differ, but the aggregate economy is on a constant growth path with constant labour shares across sectors. The model's predictions are consistent with evidence for the United States. Chapter 3 is an empirical study of the patterns of intermediates use in the United States and the United Kingdom. It shows that in both countries, since 1970s there is substitution of the goods-intermediates with the services ones in the gross output of the average industry. The increasing relative prices of the services-intermediates and the complementarity between intermediates types in the production is an important driver of this trend. The estimated elasticity of substitution is used to get measures of the latent technological and/ or policy factors that affect industries' choice of intermediates. Chapter 4 analyzes the impact of equity market information imperfections on R&D driven growth. The features of its production make R&D largely dependent on equity, which can be persistently mispriced, when the rational investors' beliefs are affected by both private and public information. Optimism in equity market raises R&D investment, resulting in technology improvement and thereby higher output, wages and consumption. Despite the capital losses, the mechanism can generate permanent gains in consumption.
