Abstract:
“Technology and the Police” primarily seeks to underline the importance of the role technology plays when it comes to law enforcement. As agents of law enforcement, police are needed to protect and defend society. From the use of DNA to video surveillance and tracking tools, technology helps police officers achieve their goal. Furthermore, technology may also serve as a means of control to make sure police are doing their job effectively. Another purpose of “Technology and the Police” is to show that unlike popular belief, the study of history does not start and ends in the past. It is a continuous process from which many lessons can be learnt and understood, it is timeless. Hence, this thesis also attempts to challenge ideas that history and technology cannot blend together because one represents the past and the other represents the present and the future.

Toft, P. N. "Management of innovation in school technology." Thesis, University of Salford, 1988. http://usir.salford.ac.uk/14795/.

Abstract:
This thesis documents and evaluates two associated topics of action research in the form of case studies in school technology. Its emphasis is on the role of strategic planning in the management of innovation within this increasingly important area of the English school curriculum. The research was carried out during a period in which British industrial innovation, and its effective management, was seen to be crucial to the nation's economic well being in the face of international competition. Growing acceptance of the importance of technology in general schooling, evidenced by its inclusion in the national curriculum embodied in the 1988 Education Reform Act, is set against the interlinked cultural, epistemological and professional barriers to its acceptance as high status activity within schools. It is argued that considerable energy expenditure is required before the intentions of the Reform Act become reality, and that innovation will need to be effectively managed. The study is therefore set against a review of the literature of innovation management in three spheres: curriculum development; the diffusion of Innovations; and industrial management. The first case study examines the implementation of an innovatory interpretation of the school subject Craft, Design and Technology (CDT) within the City of Manchester Education Authority. It tests the feasibility of developing a 'concept base' approach to CDT by teachers collaborating and being supported by the authority's inspector for CDT. It concludes that the innovation in a simple form is feasible, given that certain conditions and levels of resourcing can be met, but that in a more elaborate form, the innovation is severely problematic. The turbulence and rapid change being experienced within schools in the late nineteen eighties increases the severity of these problems. The second case study describes a project carried out in the North West of England in which various local education authorities and institutions of higher education collaborated to reduce perceived severe qualitative and quantitative shortages of CDT teachers. Five project aims were tested within the research and it is concluded that under certain conditions they are achievable, but that collaboration between institutions with different goals and customs is difficult, and that the quality of management information available to CDT staffing decision makers in the region W4S insufficiently accurate or sophisticated for effective innovation to proceed. In conclusion, certain generalisations are made relating to the effective management of innovation in school technology. These include: the inevitability of transactional distortion of objectives in the journey from intention-to outcome; the need to formulate and understand objectives and defend them from this drift, albeit in flexible ways; the need for incentives and central control in such collaborative endeavours; and finally the need for simple and effective communications within innovations.

Abstract:
Multi-hop wireless ad hoc wireless networks have no fixed network infrastructure. Such a network consists of multiple nodes that maintain network connectivity through wireless links. Additionally, these nodes may be mobile and thus the topology of the network may change with time. It will be useful if the nodes in this network could communicate with the Internet; this can be done via gateways which in turn interconnect to the Internet. This functionality requires that the nodes in the ad hoc network to discover the gateway, using a gateway discovery protocol. However, a limiting factor (particularly for mobile nodes) is suing their limited energy supply provided by batteries. In order to understand the potential effect this thesis considers two key areas: internetworking between a multi-hop mobile wireless ad hoc network and the Internet and the energy utilization as a function of number of gateways and the mobility pattern of nodes. Using simulation on various mobility patterns and networks density scenarios, we show that increase the number of gateways in ad hoc network significantly improves the power efficiency of mobile node and therefore prevent network partition due to death nodes. The thesis also discusses about the impact of different environment and mobility patterns on the power consumption of mobile nodes which is a very important factor in the building and deployment of the cost-effective high performance wireless ad hoc networks.

Cataloged from PDF version of thesis.
Includes bibliographical references (p. 269-283).
This dissertation concerns the role of place in scientific practice. Ideas of place, I argue, shape and are shaped by science. I specifically look at the community of planetary scientists who, though they cannot step foot on the objects they study, transform planets into places. This is an ethnographic work that draws on 18 months of fieldwork during which time I encountered several different communities of planetary scientists. At MIT, I worked alongside astronomers looking for planets around other stars. These "exoplanet" astronomers transformed numerical counts of photons into complex worlds with atmospheres and weather. Data visualizations characterized the work of a community learning to see unseen planets in specific, place-based ways. I also traveled with an astronomer to a Chilean observatory where she studied the night sky hoping to find a "habitable planet." Many other astronomers share this goal and have designed various ways to detect a planet like Earth. The importance of these projects signifies that exoplanet astronomers are more interested in finding planetary kin - planets that are familiar places - than exotic aliens. To determine how the planetary places created by exoplanet astronomers differ from those in our own Solar System, I spent time at the NASA Ames Research Center with a group of computer scientists who create high resolution and three-dimensional maps of Mars. These maps reflect the kind of place Mars is today: it is available to everyone to explore, it is displayed such that you can imagine standing on the surface, and it is presented as geologically dynamic in ways similar to Earth. Even though these maps help give Mars a sense of place, Martian science is still stymied by the inability to send humans to its surface. Instead, planetary scientists travel to terrestrial sites deemed to be "Mars-like" to approximate performing geologic fieldwork on Mars. I went to one of these locations to see how, during these outings, Mars and Earth become entwined as scientists forge connections between two planetary places. These diverse scientific activities, I conclude, are transforming our view of the cosmos. Outer space is becoming outer place.

Full text
Abstract:
This Thesis examines the role and limitations of voice biometrics in the contexts of security and for crime reduction. The main thrust of the Thesis is that despite the technical and non-technical hurdles that this research has identified and sought to overcome, voice can be an effective and sustainable biometric if used in the manner proposed here. It is contended that focused and continuous evaluation of the strength of systems within a solid framework is essential to the development and application of voice biometrics and that special attention needs to be paid to human dimensions in system design and prior to deployment. Through an interdisciplinary approach towards the theme reflected in the title several scenarios are presented of the use of voice in security / crime reduction, crime investigation, forensics and surveillance contexts together with issues surrounding their development and implementation. With a greater emphasis on security-oriented voice verification (due to the diversity of the usage scenarios and prospect of use) a new framework is presented for analysis of the reliability and security of voice verification. This research calls not only for a standard evaluation scheme and analytical framework but also takes active steps to evaluate the prototype system within the framework under various conditions. Spoof attacks, noises, coding, distance and channel effects are among the factors that are studied. Moreover, an additional under-researched area, the detection of counterfeit signals, is also explored. While numerous technical and design contributions made in this project are summarised in chapter 2, the research mainly aims to provide solid answers to the high-level strategic questions. The Thesis culminates in a synthesis chapter in which realistic expectations, design requirements and technical limitations of the use of voice for criminological and security applications are outlined and areas for further research are defined.

Abstract:
The present thesis addresses promising material solutions for fusion reactors from a theoretical point of view. We focus on two specific systems: W-based alloys used as plasma-facing materials and reduced activation ferritic/martensitic (RAFM) steels used as structural materials of breeding-blanket. We aim to systematically investigate the alloying effects on the micro-mechanical properties of these body-centered cubic (bcc) solid solutions. The all-electron exact muffin-tin orbitals (EMTO) method in combination with the coherent-potential approximation (CPA) are the main tools for our theoretical studies. The knowledge of the elastic parameters and their solute-induced changes is important for alloy design and for a multi-scale modeling approach to the mechanical properties. We also explore the planar faults in the present alloys by studying the surface and unstable stacking fault energies. In part one, the effect of neutron transmutation elements on the elastic properties of the W-based alloys are calculated. Both Re and Os solute atoms shrink the lattice constant, which lead to increasing bulk modulus as the amount of Re or Os increases. The polycrystalline shear and Young’s moduli of W1−x−yRexOsy (0 ≤ x, y ≤0.06) enhance with the addition of Re but decrease with increasing Os. From the variations of the Cauchy pressure, Poisson ratio, Pugh ratio B/G, and the ratio of cleavage energy to shear modulus for the dominant slip system, we conclude that the intrinsic ductility of the alloy increases with increasing Re and Os content. The classical Labusch-Nabarro model for solid-solution hardening predicts that strengthening effects in W1−yOsy is larger than those in W1−xRex. We use the energy difference between the face centered cubic (fcc) and bcc structures to estimate the alloying effect on the ideal tensile strength in the [001] direction. Within a simple empirical equation, we find that the melting temperature of W-Re-Os alloy decrease with Re and Os addition. In part two, we investigate the micro-mechanical properties of the main alloy phases of three reduced activation ferritic/martensitic (RAFM) steels: CLAM/CLF-1, F82H, and EUROFER97. Being the main building blocks of the RAFM steels, first the lattice parameters, elastic properties, surface energy and unstable stacking fault energy of ferromagnetic α-Fe and Fe91Cr9 are calculated for reference. For quantitative understanding, we present a detailed analysis of the calculated individual alloying effects of V, Cr, Mn, and W on the elastic properties of Fe91Cr9. A linear superposition of these individual rates on the elastic properties of RAFM steels is shown to reproduce well the values from ab initio calculations. The composition dependence of the elastic constants is decomposed into electronic and volumetric contributions and analyzed. Finally, the intrinsic ductility is evaluated through Rice’s phenomenological theory by using the ratio of surface and unstable stacking fault energies. The results are consistent with those obtained by the common empirical criteria.

Abstract:

År 2000 startades ett samarbete mellan Wuhan i Kina och Borlänge Energi i Sverige. De två parterna bestämde år 2005 tillsammans med IVL, Svenska Miljöinstitutet, att samarbeta inom följande områden; hållbar energiproduktion, hållbar avfallsproduktion samt grundandet av ett miljöteknikcentrum i Wuhan. Miljöteknikcentrumet är till för att vara en plattform för svensk miljöteknik och expertis. Som ett första steg inför grundandet av ett miljöteknikcentrum gjordes en undersökning för att se inom vilka sektorer svensk miljöteknik kan etableras.

Undersökningen var inriktat på industriell avloppsvattenrening i Wuhan; bedömning av vilka typer av industrier/företag som har problem med avloppsvattenreningen och i vilken utsträckning det finns svenska tekniklösningar på problemen. Undersökningen genomfördes genom intervjuer med myndigheter och en del utvalda företag. Det var svårt att få fram information om vilka företag som inte följer de kinesiska gränsvärdena, varför en del besök gjordes till företag som lever upp till gränsvärdena. På grund av detta togs även andra problem med miljön som företagen hade upp. Några kommunala reningsverk besöktes och intervjuades också för att få en bättre bild av den kommunala vattenreningssituationen. En generell beskrivning av Wuhans miljösituation utfördes också samt en beskrivning av de viktigaste miljömyndigheterna och institutionerna.

Wuhans största utmaning är att konstruera reningsverk till alla de 3.5 miljoner som fortfarande släpper sitt avloppsvatten rätt ut till sjöar och floder, snarare än att ytterligare rena det industriella avloppsvattnet. Behandlingsgraden av det industriella avloppsvattnet har nått 97 % medan behandlingsgraden av det kommunala avloppsvattnet endast nått 70 %.

Besök vid de utvalda företagen och kommunala reningsverk ledde till slutsatsen att svensk teknik och expertis kan införas i följande områden: hantering av slam från reningsverk, byggandet av förbränningsanläggningar för sopor och hur man löser problemet med att rena luften från gaser som SO2 och dioxiner. De flesta företagen kunde följa de kinesiska gränsvärdena för utsläpp av avloppsvatten men mycket kan göras för att förbättra företagens tekniker ytterligare. Detta utförs dock nästan aldrig eftersom det är en ekonomisk fråga. Det är möjligt för Wuhan att sätta lokala, hårdare gränsvärlden för att tvinga företagen att förbättra sina reningstekniker ytterligare.


In 2000 a co-operation between Wuhan in China and Borlänge Energi in Sweden started. The two parts decided in 2005 together with IVL, the Swedish Research Institute, to co-operate in the fields of sustainable energy production, sustainable waste management and the establishment of an Environmental Technology Centre, supplying Swedish environmental expertise to companies in Wuhan. As a first step for the establishment of an Environmental Technology Centre in Wuhan, an investigation was made to find out in which sectors Swedish environmental technology could be established.

The investigation took aim at observing the industrial wastewater treatment in Wuhan and to see which types of companies that have problems with the wastewater treatment and if there existed Swedish technology that could solve the problems. The investigation was performed through interviews with the authorities and some selected companies. It was difficult to get information about companies that did not comply with the National Chinese wastewater standards. This meant that some of the visits were made to companies that comply with the standards, also taking into consideration other problems with the environment that the companies might have. Visits were also paid to municipal wastewater treatment plants to get an overview over the municipal wastewater treatment situation. An overall survey of the environmental situation in Wuhan was also made and a presentation of the most important environmental departments and institutions is given.

The greatest challenge for Wuhan is to construct wastewater treatment plants for the around 3.5 million people that still discharge their wastewater directly to rivers and lakes, rather than to improve the industrial wastewater treatment further. The treatment rate of the industrial wastewater has reached 97%, but the municipal wastewater treatment rate has only reached 70%.

After the visits to the selected companies and municipal wastewater treatment plants the conclusion was made that Swedish technologies and expertise can be applied to the following areas; handling sludge from the wastewater treatment plants, construction of waste incineration plants and handling flue gas and dioxins. Most of the visited companies could follow the wastewater standards. Although much can be done to improve their technologies further, this is not done since it is too expensive. It is possible for Wuhan to apply stricter local wastewater treatment standards. This could be used as a tool to make companies invest more money in improvements of their technologies.

Abstract:
Purpose Idea Management as key activity in the front-end of innovation is crucial for not only targeting new products but also for new technologies. Nevertheless, the interrelations between Idea Management and Technology Development are still not fully understood. Due to the different abstraction levels of products and technologies, an in-depth investigation of evaluation criteria for Technology Development ideas is required. Therefore, the purpose of this thesis is to examine which evaluation criteria are pertinent for each phase of Idea Management, when applied for Technology Development. Design The research framework for Idea Management criteria in the context of Technology Development is built on data from 17 semi-structured interviews, two focus group interviews as well as participant observations. The participants of this study are experienced R&D experts from a large Swedish organization in the transport industry. Findings The results indicate that the evaluation of Technology Development ideas is more complex due to the high degree of uncertainty and unpredictability. In contrast to the common one-step evaluation process of New Product Development ideas, the findings suggest a three-step evaluation process for Technology Development ideas. Due to the lack of knowledge and maturity when an idea is generated, this three-step evaluation enables a continuous reduction of uncertainty. In addition to this, the result of this study contributes with the suggestion to attribute a focus dimension for each Idea Management phase, which in consequence is helping firms to direct their evaluation resources. The findings are presented in a generic evaluation framework that leads organizations through the assessment process. Theoretical contribution The present study contributes to the literature with an improved understanding of TD idea evaluations by suggesting a rather internally use-oriented perspective as well as advances prior research through knowledge about the right timing for the use of evaluation criteria. Practical implications Irrespectively of the origin or focus of an idea, evaluation criteria are helping to direct Technology Development initiatives. By having evaluation criteria, defined as pertinent for each phase of Idea Management, Technology Development ideas can be assessed appropriately regarding their contextual circumstances. Originality The study is among the first that differentiates Idea Management for Technology Development from the one targeting New Product Development. This study suggests a framework that considers the stages and criteria necessary in the context of TechnologyDevelopment.

Full text
Abstract:
Information and communication technologies (ICTs) are an important part of society today. Older adults often report ICTs as difficult to use and unhelpful; however, ICTs can support older adults’ ability to stay in touch with family and friends across long distances and help increase their quality of life. Unfortunately, training programs targeted at teaching older adults to use ICTs are often costly and time-consuming. The current study attempts to determine whether advertisements depicting older adults using ICTs can be used to increase self-efficacy without the use of training programs. A within subjects experimental design was completed using an independent variable in which participants viewed two advertisements. Participants were randomly assigned to view an advertisement PowerPoint depicting younger adults using technology first, or randomly assigned to an advertisement PowerPoint depicting older adults using technology first. The dependent variable was a Technology Self-Efficacy Survey developed for the purposes of this study. Results of a paired samples t-test indicated that participants did not rate their selfefficacy higher after viewing the PowerPoint with older adults depicted using technology, as compared to viewing the PowerPoint with younger adults depicted using technology. Although the results were not statistically significant, this research indicated that older adults generally rated their self-efficacy higher after viewing the PowerPoint with older adults versus the PowerPoint with younger adults. Future research could help determine whether advertisements could be used to increase technology self-efficacy in older adults.

Abstract:
Energy is an important requirement for population growth, technological progress and urbanisation. Worldwide energy demand has been projected to increase by 5-fold by 2100. Fulfilment of these energy requirements cannot be solely from fossil fuels, such as oil, coal and natural gas, on account of their adverse environmental impacts and concomitant depletion of natural resources. As a result multiple approaches for generating alternative energy are being explored globally. In this study, processed municipal solid waste (MSW) fibre was assessed as a substrate for the production of various bio-energy related products. The MSW was characterised and the results showed that there was, as expected, a wide compositional variation between samples. There was a significant amount of lignocellulosic material found in some samples and the potential to exploit this to generate fermentable sugars was explored. Direct enzyme hydrolysis using 30 FPU (Filter Paper Units)/g Cellic® CTec2 gave a 30 % release of available glucose. Pre-treatments- using hot water, dilute acid and dilute alkali are all applied to enhance sugar release but were all found to be ineffective. The possibility of using MSW as a substrate for cellulase enzyme production via solid state fermentation (SSF) by Trichoderma reesei (T. reesei) and Aspergillus niger (A. niger) was explored. Both fungi grew well on the substrate and following optimization a cellulase activity of 26.10±3.09 FPU/g could be produced using T. reesei at 30 °C with a moisture content of 60 % with inoculation of 0.5 million spores/g and incubation for 168 hr. Addition of extra nitrogen and/or carbon did not improve cellulase accumulation. Acid or alkali pre-treatment of MSW led to reduced cellulase production. Crude enzymes produced from MSW by T. reesei were evaluated for their ability to release glucose from MSW. A cellulose hydrolysis yield of cellulase was 24.7 % achieved, which was close to that obtained using a commercial enzyme. Results demonstrated that MSW could be used as an inexpensive lignocellulosic material for the production of cellulase enzymes. High concentrations of toxic heavy metals were found in all MSW samples tested and this precludes the use of this material as a soil enhancer. Thus studies were undertaken to explore the potential for bioleaching as a means to generate compost that meets environmental standards for safe use. A. niger and Saccharomyces cerevisiae NCYC2592 were used and the impact of growth medium and pH tested. Both organisms were effective at solubilising the heavy metals and this may be related to their ability to synthesise organic acids into the fermentation medium that act as chelators.

Abstract:
This study investigates teacher cognition and technology use within a context of teaching Arabic to speakers of other languages. Specifically, teacher cognition is examined in relation to early learning experiences, teacher education, classroom practice, and work environment. Following a case study approach, three in-service teachers have been selected to represent different perspectives on using Information and Communications Technology (ICT) in language instruction. Findings suggest that teachers’ cognitions about teaching and learning, and about themselves as Arabic language professionals, shape technology use, determine reactions to perceived challenges, and illuminate differences between practitioners working within the same environment with regard to the integration of ICT into their practice. The research suggests that despite the absence of digital learning opportunities in early schooling and teacher education, these experiences still influence the choice of instructional strategies employed by teachers to support technology use. The study accentuates the role of context as a mediating force, supporting teacher cognition and ICT use, but also creating dissonance between them. Teacher cognition determines the weight that practitioners assign to different contextual factors. While lack of time is identified as the most significant barrier to adoption, peer collaboration is recognized as the most effective enabler for technology integration. Other key factors emerging in this study include institutional philosophy and policy, learning opportunities, and technical support. Conceptual, methodological, and professional contributions are addressed, and potential for further research is identified.

An IoT device measuring soil moisture to help a municipality improve the work surrounding irrigation is deployed for testing and used by the concerned municipal workers. The IoT device is an initial prototype using Pycom’s LoPy4 with expansion board 3.1 and 3xAAA batteries as power supply. The prototype is not suitable for larger-scale testing due to the size, cost, and power consumption. This thesis focuses on decreasing the cost and size while increasing the battery life for the IoT device.The IoT device is communicating using the LoRaWAN protocol. For the device to be as energy-efficient as possible, the LoRa and LoRaWAN protocol are explored to use all possibilities to save energy. Active time and power consumption between different spreading factors are examined and discussed for power consumption and range concerns. The prototype produced by the work performed in this thesis is used to measure soil moisture. The microcontrollers selected and tested will not restrict to that purpose. The microcontrollers can integrate with many kinds of sensors. Integration with other types of sensors is under future work in this thesis.

Abstract:

Törestorps Tråd AB är ett företag vars viktigaste produkt är engångskrokar för användning vid pulvermålning av olika detaljer t.ex. inom bilindustrin. För att öka kunskapen om hur olika parametrar påverkar krokarnas mekaniska beteende har dragtester utförts. Dessa tester har utförts med hjälp av en dragprovmaskin och en ugn.

För att se vad som händer när konsumenterna avlägsnar färgen på krokarna som uppkommer vid pulvermålning, har krokarna utsatts för värmning i 450°C resp. 600°C, i båda fallen under tiderna 30 resp. 60 minuter. Resultaten från proven visar att maxbelastningen sjunker med hela 40 % när krokarna har utsatts för temperaturen 600°C. En sådan behandling är därför inte att rekommendera. Dock ökar maxbelastningen något vid en värmning vid 450°C.

Dragprov har också gjorts på icke värmda krokar för att få fram hur parametrar som längd, diameter, form, bockningsavstånd, material och storleken på detaljen påverkar det mekaniska beteendet. Resultaten visar tydligt att den viktigaste parametern är diametern, och genom att dubbla denna från 2 mm till 4 mm kan kraften ökas hela 6 gånger. Andra parametrar som orsakar styrkeförändringar är materialet och formen på kroken.

Abstract:
This thesis describes the development of two novel circuits that use a newly developed technology, that of neuron-MOS, for the purposes of analogue-to-digital conversion and image enhancement. Neuron-MOS has the potential to reduce both the complexity and number of transistors required for analogue and digital circuits. A reduced area, low transistor-count- analogue-to-digital converter that is suitable for inclusion in a massively parallel array of identical image processing elements is developed. Supporting the function of the array some fundamental image enhancement operations, such as edge enhancement, are examined exploiting the unique features of neuron-MOS technology.

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:
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:
Taking part in regular physical activity leads to adaptive response that enables the body’s antioxidant defence to be better equipped to fight against oxidative stress. Exercise intensity seems to be one of key factors that determines the effectiveness of exercise. The work presented in this thesis used novel approaches, through the application of emerging technologies, to study physical activity and its effects. This thesis contributes to the existing literature by being the first to investigate the effect of exercise on a marker of oxidative stress in the brain, an organ that becomes impaired (including oxidative damage) with ageing and diseases associated with ageing. The finding from this thesis suggests that brain glutathione (GSH) of young sedentary men as measured by magnetic resonance spectroscopy (MRS) was altered in response to acute exercise, in an exercise intensity dependent manner. Observed changes in peripheral markers of oxidative stress were also exercise intensity dependent. The brain seems to be protected against hyperperfusion injury during high intensity phase of high intensity interval exercise. Objectively measured physical activity levels were not significantly increased by an unsupervised home-based exercise intervention in older adults, potentially due to a lack of progressive goals based on adherence to physical activity.

Abstract:
Banverket (‘the National Swedish Railway Administration') is responsible for management of the infrastructure in Sweden. The main objective of Banverket, stated by the Swedish government, is to assure a cost-effective and long-term provision of transportation for citizens and the business sector. In order to stay competitive with other forms of transportation, the railway needs to be cost-effective and provide reliable service. The reliable service is to a great extent reflected in terms of train punctuality. Railway components in general have a fairly long life, which means that the cost effectiveness of the transportation system is highly dependent on the effectiveness (doing the right things) and the efficiency (doing the things right) of its operation and maintenance process. The purpose of maintenance is to ensure business objectives through the assurance of required technical functions. Maintenance in the railway ensures the function of the systems that are es-sential for the operation of the transportation system. In other words, maintenance is a vital tool for achieving punctuality, which next to safety is Banverket's most important goal area. Developments in sensor technology and in the information and communication technology sector have provided new opportunities to use technology to assess infrastructural and rolling stock conditions. Decision support derived from condition monitoring systems can provide opportunities for improved maintenance management. In other words, condition monitoring can provide conditions for improved maintenance effectiveness and efficiency and hence punctuality. The thesis explores three areas. The first area is the exploration of current train delay statistics, performed in order to assess how the statistics can represent the influence of different factors on punctuality. The second is an exploration of the link between punctuality and maintenance and more specifically condition monitoring. The third area explores current condition monitoring applications at Banverket to form a knowledge foundation for further condition monitoring implementations intended to improve the reliability and hence the punctuality of the transportation system. In the perspective of the studies are important factors for successful applications of condition monitoring technology proposed. These are factors such as knowledge of problem characteristics, information accuracy, measurement limitations and ability to combine condition based maintenance objectives with business objectives etc. Furthermore, are recommendations for future condition monitoring implementations made. These are recommendations for enhancing the condition-based maintenance, which in turn is dependent on applications of condition monitoring. The final discussions are based upon overall experience from working with the material. The discussion links to the initial research problem, whose intension is to widen the horizon of possible condition monitoring applications.

Abstract:
En stor del utav dagens vårdtagare är äldre personer och majoriteten utav dessa vill kunna bo kvar i det egna hemmet under så lång tid som möjligt. Det som oftast hindrar dem är deras olika behov och funktionshinder som gör att de ständigt är i behov av någon annans hjälp. Detta bidrar till en otrygghet bland de äldre och en minskad livskvalitet i samband med oro och att man inte kan vara självständig på samma vis som förr. Dessutom är hemtjänsten i flera delar av Sverige högt belastad. En kombination av detta gör att resurserna inom vården inte räcker till för att täcka upp de behov som finns bland vårdtagarna. Med hjälp av informations- och kommunikationsteknologi så kan man effektivisera vården och bidra till en bättre användning av de befintliga resurserna. Detta ska medföra att arbetet underlättas för vårdgivarna och ge en ökad kvalitet inom hemtjänsten. Effekten av digitala lösningar inom vården ska öka självständigheten hos vårdtagarna, öka levnadsstandarden och skapa en större trygghet bland dessa och deras anhöriga. Med hjälp av applikationen Trixxa och Halmstad Intelligent Home så har man utvecklat TICaP, en kommunikationsplattform med implementerade sensorer och funktioner. Med hjälp av TICaP kan vårdgivare, vårdtagare och deras anhöriga kommunicera med varandra, sätta upp olika arbetsuppgifter samt få realtidsinformation om den aktuella vårdtagaren. Med hjälp av denna tjänst så kan man lösa många olika behov som finns bland vårdtagare som är beroende av hemtjänst. Även få en bättre koll på hur läget ligger till för vårdtagaren i hemmet. Man kan direkt få en notis om vårdtagaren behöver hjälp, har tagit sin medicin eller om vad man vill, man bestämmer själv vad notisen ska säga. Detta leder till en ökad trygghet hos vårdtagaren då han eller hon vet med sig att anhöriga och vårdgivare får direkt information samt en ökad trygghet för de anhöriga som enkelt kan ha kolla på vårdtagarens tillstånd via applikationen.
A majority of today's caretakers are older people and most of them want to be able to stay in their own homes for as long as possible. That which usually prevents them is their different needs and disabilities, which means that they are constantly in need of someone else's help. This leads to an insecurity among the elderly and a reduced quality of life in contribution with anxiety and the fact that they cannot be as independent as before. Also, the home healthcare system in Sweden is highly burdened. A combination of these factors makes the resources available to the home healthcare system insufficient to meet the existing needs of the caretakers. With the help from information- and communications technology you can streamline the home healthcare system and contribute to make better use of existing resources. This should make the work more effective for the caregivers and increase the quality of the home healthcare system. The effect of digitalized solutions in home healthcare systems should increase the independence for the caretakers, raise the standard of living and create greater security among them and their relatives. With help of the application Trixxa and Halmstad Intelligent Home, TICaP has been developed, a communications platform with implemented sensors and functions. With the help of TICaP, caregivers, caretakers and their relatives can communicate with each other, set up different tasks and get real-time information about the current caretaker. With the help of this service you can solve many different needs that exist among caretakers who are dependent on the home healthcare system. You can also get a better understanding of how the situation is for the caretaker in their own home. You can immediately get a notification if the caretaker needs help, if the caretaker has taken his medicine, or on what you want basically, you decide for yourself what the notification should say. This leads to an increased sense of security for the caretaker as he or she knows that the relatives and caregivers receive direct information, as well as an increased sense of security for the relatives who easily can oversee the general condition of the caretaker through the application.

Abstract:
Electric scooters, or e-scooters as they also are called, were launched in California in USA as a bike share system, in 2017. A year later, in September 2018, the Swedish company Voi Technology launched the first e-scooters in Stockholm, Sweden. Bike share systems has been around since the 1960s but has grown substantially in the past 15 years. New technical solutions have solved past problems with theft and payment in bike shares. Since e-scooters are new, there is a lack of research and knowledge about practical use. The study aims to examine how long users of e-scooters walk to utilize the service. Travel data from Voi Technology is used to determine walking distance. The distance from the location where the app was opened to the location where the e-scooter trip begun was measured. The result was also compared the walking distance of other bike share systems and travelers of public transportation. The majority of e-scooter users walk less than 100 meters and 38 per cent walk less than 50 meters. The users have the shortest walking distance in the morning and the longest in the afternoon. During the weekend's users walk further than in weekdays. The users who travel longer distances with the e-scooters don’t walk further than other users. About a third of the users walk in the opposite direction of travel, to some extent, to catch an e-scooter. That indicates that the aim of the user in general seems to be to always have the shortest possible walking distance to the e-scooter.

Abstract:
Acts of insurgency have become an increasing threat resulting in extensive measures being taken by the law enforcement authorities to mitigate their devastating effects on human life and infrastructure. This thesis introduces a magnetometry-based information, and signal processing methodology for detecting concealed ferrous objects in vehicle body panels. From extensive literature research, it was observed that while magnetic sensors have been used in a variety of related applications, but they have not been extensively applied to the on-road detection of firearms and explosives concealed in vehicles. This study utilized an extensive experimental protocol for preliminary concept validation. The main idea behind the approach was that almost all concealed weapons and explosives are made up of a considerable amount of ferrous material, and hence produce a local distortion in the Earth’s magnetic field. This distortion can then be identified by utilizing sensitive magnetic sensors. To detect concealed ferrous objects, magnetic signatures of a vehicle door panel were obtained by using a scanning assembly design in this thesis project, and compared to a base magnetic signature of the same vehicle door panel. The base magnetic signature is the magnetic field data of the same vehicle where no foreign ferrous objects were present. To analyze the data, a signal processing methodology was designed. To achieve the objective of accurately detecting concealed ferrous objects, simple measures such as magnetic field strength and its energy density were computed. These simple measures were then used in conjunction with more sophisticated statistical methods such as, normalized cross-correlation and Mahalanobis distance. Although all these methodologies were able to detect a magnetic footprint anomaly in the presence of a concealed object, the Mahalanobis distance approach, in particular provided the most conclusive results in all the test cases considered.

Abstract:
The study has been conducted in collaboration with Swestep AB, a Swedish company that specializes in the conversion of waste to valuable products via the KDV technology. The study explores the possibility of using cassava chips and cassava pulp as a potential feedstock in the production of synthetic diesel and compares the KDV method with fermentation, a conventional method of using cassava chips and cassava pulp in Thailand. To obtain the carbon yield, amount of product and system efficiency, a mass and energy balances were first performed on wood feedstock data provided by the company. The balances were thereafter used as a basis for a simulation analysis of the cassava feedstock. The diesel product yield is produced through a KDV 150 plant using 551kg/h of the different feedstock; wood, cassava chips and cassava pulp resulting in different amounts of diesel product 150 L/h, 116.79 L/h and 121.31 L/h, respectively. For cassava, the C yield in diesel is 0.41 while the C yield of ethanol production is 0.14, since C in the ethanol production is converted into other matters. Besides, the system efficiency of the KDV plant with different types of feedstock is around 0.84 because some parts of the KDV plant is self-supplied whereas the ethanol production plant (55% of system efficiency) is not. Economical evaluations of the KDV 5000 and ethanol production plant were performed. The KDV 5000 with cassava pulp as feedstock produces 31 ML/year and is feasible for investment in Thailand due to the low price of the feedstock which is driving the operation cost (15.167 baht/L or 0.46 USD/L). This is lower than the selling price (21.329 baht/L or 0.65 USD/L) whereas the KDV 5000 plant with cassava chips is not feasible. The KDV plant with cassava pulp as a feedstock will reach the breakeven point after running for 7 years. The ethanol production process with cassava chip as feedstock produces 49 M liter/year and has an operation cost of 19.693 baht/liter (0.6 USD/L) which is higher than the KDV plant due to the feedstock price. The selling price of ethanol is 23.11 baht/l (0.705 USD/L) which resulted in the process reaching the breakeven point after 14 years.

Abstract:
Moduler l’agrégation de protéines amyloïdes est thérapeutiquement pertinent (p. ex. la polyneuropathie amyloïde familiale traitée avec le Tafamidis). Cependant, pour de nombreuses amyloïdoses, il n’existe pas encore de modulateur d'agrégation efficace pour thérapie. Il a été récemment montré que combiner des composés qui modulent l’agrégation d’amyloïdes peut résulter en des effets synergiques. Une stratégie de criblage combinatoire, pour identifier des cocktails synergiques de composés, pourrait donc conduire à une percée thérapeutique pour de nombreuses amyloïdoses. Cependant, les technologies à haut débit existantes ne sont pas adaptées pour le criblage combinatoire.J’ai développé SynAggreg – une technologie in vitro à haut débit très sensible, précise, reproductible, peu coûteuse et flexible - qui permet d'identifier à la fois des inhibiteurs et des accélérateurs d'agrégation, de caractériser leur mécanisme d'action sur la cinétique d'agrégation et de les classer par leur efficacité. SynAggreg est également la première technologie adaptée au criblage combinatoire et pour l’étude d’effets synergiques de manière fiable. Enfin, cette nouvelle technologie peut être facilement adaptée à plusieurs amyloïdoses en remplaçant la partie amyloïde de la protéine de fusion par des techniques de biologie moléculaire. Ainsi, SynAggreg apparaît comme une boîte à outils pour la recherche fondamentale et appliquée et possède un fort potentiel de valorisation
Modulating amyloid proteins aggregation is therapeutically relevant (e.g. the familial amyloid polyneuropathy treated with Tafamidis). However, for many amyloidoses, there is yet no efficient aggregation modulator for therapy. It was recently shown that combining compounds that modulate the aggregation of amyloids can result in synergistic effects. A combinatorial screening strategy to identify synergistic cocktails of compounds could thus lead to a therapeutic break through for many amyloidoses. However, existing high-throughput technologies are not adapted for combinatorial screening.I developed SynAggreg - a very sensitive, accurate, reproducible, cost effective, flexible and high-throughput in vitro technology - which allows identifying both aggregation inhibitors and accelerators, characterizing their mechanism of action on aggregation kinetics and ranking them by their efficiency. SynAggreg is also the first technology suitable for combinatorial screening and for studying reliably synergistic effects of combinations of compounds. Finally, this new technology can be easily adapted to several amyloidoses by replacing the amyloid part of the fusion protein with molecular biology techniques. Thus, SynAggreg appears as a toolbox for fundamental and applied research, and has a high potential for valorization

Abstract:
Developing an app for Android and iOS traditionally requires you to build two different versions. This is both costly and time consuming, which has led to the creation of many Cross-platform alternatives. One such alternative is to use a Progressive Web App (PWA). They are built like regular Web apps and include features previously unique to Native apps. Our focus is to compare PWAs to other Cross-platform solutions by measuring the performance of a PWA, Web app and Cordova app. Terms in the ecosystem are clarified due to inconsistencies, and the process of converting a Web app into a PWA is described. The measurements showed that the PWA and Cordova app had almost equal overall performance, and they were both faster than the Web app. This indicates that PWAs are a viable Cross-platform alternative, but more quantitative studies with performance in focus needs to be conducted due to the small scale of this work. Other aspects of PWAs also needs to be evaluated, such as app size and ease of development.

Abstract:

The present work has as aim implementing a CAD and rapid prototyping based production process in a porcelain company. There is considerable interest in ceramic companies in implementing new digital technologies in an old-fashioned industry, where traditional handscraft predominate.

 

The work is carried out in collaboration with Rörstrand Kulturforum AB, whose current process is analyzed, pointing out strengths and weaknesses, to define where to set the focus and the actions to perform. This analysis goes from early stages of product design to slipcasting clay bodies, the forming process of porcelain that uses plaster moulds.

 

As a result of this analysis, some alternatives including rapid prototyping and CNC milling techniques are defined and compared to one another. Eventually, the definitive solution features CNC milling as the main prototyping system, shaping the mother moulds out of a polyurethane block. This process skips some initial steps, such as manual modelling and mould casting, resulting saving in the new product development. Anyhow, the new process is yet to be tested in the company’s own environment to fully implement it, regarding to various parameters such as the size of the production and the complexity of the products to be manufactured.

Abstract:

To be able to retain the manufacturing industry durably, in Europe in general and in Sweden in specific, manufacturing companies have to be competitive also on the global market. One way for companies to realize this ambition is to interact with suppliers and customers in different kinds of supply chains. In the dyadic relation between two companies, three different levels of interaction have been identified. To be able to enhance the competitiveness instead of requiring excess workload, the level of interaction has to be adequate for the specific company and their market conditions.

The aim of this thesis is to clarify the characteristics of supply chain interaction, both in terms of different levels of interaction and concerning the factors affecting the appropriate level of interaction. A basic prerequisite to enable companies to select an appropriate level of interaction within their supply chain is also to clarify the present use of terminology.

This research is conducted through theoretical studies. The theoretical findings are synthesized in order to fulfill the research objective.

Characteristics of supply chain interaction in terms of affecting categories and factors are identified. The factors are sorted according to the category they support. An interaction framework that can be used to gain an overview over the categories and factors affecting the level of interaction in a specific situation is developed.

The resulting interaction framework is aiming at industry applicability but is based only on theoretical studies (which in turn are based on empirical data).

The aim is to support the interaction level decision for, primarily, small and medium sized manufacturing companies in order to increase their competitiveness.

Despite the amount of research within the supply chain area, the question how companies should select the way to interact within their supply chain has so far been left unanswered. In this thesis, a number of categories and factors that affects the appropriate level of interaction are identified and listed.

Sammanfattning

Monteringshallen hos Metso Paper Karlstad är beroende av många utomstående funktioner och processer. De som jobbar med montering och utcheckning måste koordinera sina arbeten med tillverkningen, underleverantörer, inköp, konstruktion och skeppning.

Alla är medvetna om att det finns problem i monteringshallen och att det måste det göras något för att komma till rätta med dem. Men vilka orsakerna är till problemen finns det olika uppfattningar om. En del upplever det också som att problemen återkommer gång på gång. Få försök har gjorts för att på metodiskt sätt få en gemensam syn på problematiken eller ta fram fakta som kan ligga till grund för beslut om förbättringsområden. Dessutom finns en attityd om att kvalitetsarbete mest tar tid. Problemen anses inte härröra från montaget utan de får helt enkelt finna sig att vara de som städar upp efter andra.

Syftet med detta examensarbete har varit att svara på frågeställningar om problemens orsaker, dess kostnadsstorlekar och vilka åtgärder som kan vara lämpliga för att minska kvalitetsbristkostnaderna i monteringshallen. Det övergripande målet har varit monteringshallens utveckling av kvalitetsarbetet. Rapporten är baserad på de anställdas erfarenheter som framkommit vid intervjuer. Teorin är vald med fokus på de olika delar som krävs för långsiktigt och kontinuerligt kvalitetsarbete.

Intervjuerna visar att medvetenheten om sin egen del i problem och problemlösning är låg. De betraktar sig själva som om de inte har del i problemen. Detta är mindre bra eftersom det finns många beroenden till andra funktioner. Dessutom behandlas det många varianter av maskiner vilket än mer ökar behovet av väl fungerande processer. Därför är den nuvarande attityden och kvalitetstänkandet ett stort hinder mot nödvändigt förbättringsarbete. Orsakerna till omarbetningar lagras inte vilket försvårar möjligheterna att på ett effektivt sätt finna lösningar på problemen.

Rapportens resultat är en genomgång av de nödvändiga byggstenar som krävs för att långsiktigt kunna bedriva framgångsrikt kvalitetsarbete. Det rekommenderas att personer med chefsbefattning tar in de synpunkter som har påpekats och gör en prioritering av det som behöver åtgärdas. Nedanför listas förslag på åtgärder för ett förbättrat kvalitetsarbete i monteringshallen.

1. Tillsätt en resurs som jobbar aktivt med förbättrings- och kvalitetsfrågor (förbättringssamordnare/ledare).

2. Börja med pilotgrupp/avdelning som får utbildning i kvalitetsmetoder och verktyg parallellt med förbättringsarbetet.

3. Informera och utbilda personalen i grunderna inom kvalitet för att få ett gemensamt språk

4. Våga genomföra förändringar.

5. Börja med att åtgärda saker som ger tydliga förbättringar med hjälp av 5S

6. Förbättra Baan-systemet så att det går att spara felorsaker

7. Kartläggning och förbättring av processerna

Abstract

This report is the result of an examination work at the University of Karlstad. The purpose of this project is to examine how the condition of the steam affects the efficiency of the steam consumers and how variations in that condition affect a pulp and paper mill.

This report is meant to describe the main components regarding steam production, steam conditioning and steam consumption. It should also be able to give basic information about the significance of steam conditioning in the pulp and paper industry. It is aimed to people working with steam conditioning to increase their understanding and knowledge about it.

The aim of this report is to:

• Describe the function of the most commonly used steam generators and the difference between these.

• Identify the main steam consumers and describe their function.

• Give an introduction to steam conditioning and its role at a pulp and paper mill.

This report will try to answer the following questions:

• How does the generated power from back-pressure steam turbines vary with grade of superheat of outlet steam?

• What are the advantages with steam conditioning?

• Are the steam conditioners at Gruvöns bruk able to deliver steam at the right condition?

The conclusions from this report are that;

• If the steam conditioning valves are able to reduce small steam flows to the correct temperature, more power can be produced. The design condition of the steam turbines can than be nearer saturation.

• The temperature variations are more critical at the turbine inlet than downstream the steam conditioning valves. The valves at Gruvöns bruk who are studied in this report, are fully functioning.

• Common for the main steam consumers at pulp- and paper mills are that they are all sensitive for variations of steam temperature, especially high temperature.

Abstract:
Technology and communication skills simultaneously increase organizational productivity and decision-making. However, excessive use of technology to make decisions can diminish the added benefits that nonverbal communication can bring. The interpersonal sensitivity effects on perception of service quality model, face-to-face communication versus teleconferencing, the technology acceptance model, and decision-making were the conceptual framework of the study. The research questions examined how excessive use of technology to make decisions can diminish the added benefits that nonverbal communication can bring to organizational leadership decision-making. Employing an exploratory multiple case study design, organizational leaders from the Southern California region, ranging in seniority from team-leader through executive, completed 25 member-checked interviews and 15 qualitative questionnaires. Using Yin's 5-step approach to analyzing the data, 8 themes remerged. From these themes, I developed 5 findings regarding technology, non-verbal communication, and decision-making. My study affects positive social change by educating organizational leaders on the importance of distancing themselves from work during nonwork hours, encouraging organizational leaders to develop guidelines around the use of teleconference software, promoting organizational learning with an emphasis on soft-skill training, and acknowledging when there is a misunderstanding in nonverbal communication. Organizational leaders can improve decision-making by using the favorable traits associated with both electronic and nonverbal behavioral communications.

Abstract:
Within the paradigm of Sociocultural Theory, and using Activity Theory as a data-gathering and management tool, this microgenetic case study examined the processes - the growth, change, and development - engaged in by student-teachers in a foreign language education program as they worked together to complete an activity. The activity involved digital video recording and editing, mediators which were intended to facilitate the iterative review of and subsequent reflection and action upon the content of the video during its creation. By investigating the process of contextual interaction between learners and the mediational elements of their environment as the activity progressed, this study intended to further understanding of preservice teacher development in at least two important ways. The aims of this study were to discover a) tangible evidence of cognitive transformation (development in the form of regulation), as well as b) aspects of professionalization into a community of skilled second language teachers (as evidenced by activity). The present study took place in a graduate-level foreign language/TESOL education practicum course. The activity involved the making of a digital video to explain and exemplify a given second language instructional approach, as well as the rationale behind and methods of targeting a specific language skill. Using theoretical constructs previously shown to be effective in the pedagogy of teacher preparation, the creators of this task endeavored to design a socially- and artifact-mediated activity with the potential to broaden and deepen student-teachers' pedagogical and professional knowledge. The student-teachers failed to engage in meaningful dialogical or critical reflection as they engaged in the task, and made no perceptible regulative movement. What ultimately was revealed in the case of the study participants was a disconnect between the intentions of the core-task designers and the outcomes effected by the student-teachers. The data gleaned from this close examination of student-teacher processes was revelatory in terms of the quantity and types of factors that appeared to significantly impact the outcomes of the project. These factors have the potential to inform the process of translating socio-cultural theory into pedagogical practice, and should be of interest to anyone involved in the development of student-teachers, including those who design or deliver preservice teacher curricula. Discussed are the possible explanations for the disconnect between the designers and administrators of the activity and the participants in the study. Also considered are the potentially serious implications for second language teacher education programs and their curricula in terms of the application of sociocultural constructs to learning tasks and environments. Recommendations include increased scaffolding by the course professor through direct guidance, as well as by structuring tasks to facilitate students' ability to collaborate and to perceive and resolve the conflicts, contradictions, and tensions that arise during the course of the activity. On a broader level, serious examinations of teacher education programs and curricula are also recommended to look for ways to better understand, align, and achieve the goals of teacher developers and those of their student-teachers.
