Full textAbstract:
This study explores the issues involved in the theoretical bases, rationale and implementation of practical work in junior secondary science programs. The part that practical work has played in science education, both internationally and in Australia, is reviewed. Links are made between statements made by science educators more than 200 years ago to those made by modern day researchers into science teaching and learning. The study draws together the research traditions of the philosophy of science, science curriculum development, learning environments, and educational psychology. The researcher has carried out a multi-stage field study using both qualitative and quantitative methods to achieve the objectives of the study. Developments in the philosophy of science as they impinge on science education are reviewed. Science practicals are defined for the purposes of this study and a new Theoretical Model for Science Practicals is proposed. The model enables the description and statement of purpose of eight types of science practicals. The target population of the study is Australian science teachers and students. The model provides a theoretical basis for the development of the survey instrument, Science Practicals Inventory (SPI), to investigate students’ perceptions of the use of practicals in science learning. The eight types of practicals described in the model were used as the scales for the SPI. Qualitative data collected during separate group interviews of science teachers and students supported the development of the SPI together with quantitative data from three pilot studies. The SPI was validated using samples of high school students from Tasmania and Western Australia.Using statistical procedures involving factor analyses, alpha reliability, discriminant validity, and ANOVA, a valid, reliable, efficient, eight scale, 50 item instrument has been developed. Analysis of the quantitative and qualitative data in this study enabled issues involved in the theoretical bases, rationale and implementation of practical work in junior secondary science programs to be clarified and better understood. The results of this study include implications for science curricula and recommendations for further research and are generalizable to science teachers and students in Australia. The SPI is available for further application in action research, science program evaluation, science teacher professional learning and science program renewal.

Full textAbstract:
Even though Scrum is nowadays widely known in the Software Industry field and its theoretical frame extensively described in the literature, its implementation is far from being straightforward. As a matter of fact, the literature describes a meta-process that new practitioners must adapt to their project specific constraints. However, this practical aspect is crucial and very scarcely tackled. To that extend, this thesis work describes the difficulties we faced while putting Scrum into practice and how, through the study of the project contextual factors, the insight of a Proof Of Concept and the support of a couple of agile practices, we worked it out.

Essa tese busca elaborar o fenômeno da circulação de saberes sobre Jornalismo na sociedade em midiatização, especialmente no que concerne à compreensão de articulações entre circuitos estabelecidos e fluxos comunicacionais mais tentativos de prática e crítica jornalística. Para tanto, são observadas experiências de práticas jornalísticas (produção de blogs e sites por amadores e apropriação de notícia s em redes sociais) e experiências de críticas jornalísticas (circulação de textos acadêmicos e de especialistas em Jornalismo na Internet). A partir da análise desses casos, que são observados tão somente em suas características que servem ao fenômeno, busca-se apreender a relação (afetações, promessas e expectativas) entre circuitos e fluxos comunicacionais de prática e crítica jornalística na sociedade em midiatização. Os referenciais teóricos que tensionam esses observáveis derivam de perspectivas da midiatização desenvolvidas especialmente por Braga (2006; 2012a; 2014). Quanto à prática jornalística, essa tese produz inferências sobre a capacidade que os amadores têm em dominar lógicas midiáticas e criar seus próprios espaços de produção de sentidos e narrativas sobre o mundo, à parte de, mas também em relação, aos grandes meios de comunicação de massa. Acerca da crítica jornalística, as inferências produzidas revelam um cenário em que os circuitos acadêmicos já estabelecidos se fecham entre os próprios pesquisadores, enquanto que fluxos comunicacionais de crítica sobre a produção dos meios de comunicação são exercidos, ainda de maneira dispersa e tentativa, via redes sociais. Em ambos os eixos de análise – de prática e crítica jornalística – verifica-se, sobretudo, que saberes em Jornalismo circulam na sociedade em midiatização, independente da atuação de circuitos acadêmicos ou profissionais.
This thesis seeks to elaborate the phenomenon of circulation of knowledges about Journalism in the mediatization of society, especially as regards the understanding of linkages between established circuits and communicational flows more tentatives of practice and criticismo journalistic. To this end, experiments of journalistic practices (production of blogs and sites by amateur and appropriation of news in social networks) and the experiences of journalistic criticism (circulation of academic texts and experts in Journalism on the Internet) are observed. From the analysis of these cases, that are observed only in its features that it work to the phenomenon, we seek to apprehend relations (affectations, promises and expectations) between circuits and communicational flows of practice and criticism journalistic in the mediatization of society. The theoretical frameworks that work these observables are mediatization's perspectives specially developed by Braga (2006, 2012a, 2014). As for journalistic practice, this thesis produces inferences about the ability of amateurs to dominate media logics and create their own spaces of production of meanings and narratives about the world, apart from, but also in relation to major media. About journalistic criticism, the inferences produced reveal a scenario in which academics circuits established are closed between the researchers themselves, while comunicational flows of criticism about the production of the major media are exercised, in a dispersed and attempt manner, in the networks social. In both lines of analysis - of the practical and the criticism journalistic - we can saw that knowledges about the Journalism are circulating in the mediatization of society, regardless of the performance of academic or professional circuits.

The purpose of this thesis is to extract and provide practical knowledge and examples from both theory and practice in order to clarify some practices that can be used in the implementation of open innovation. It can be of interest for whomever willing to gain an insight into the practical features of open innovation and for companies considering, or struggling with the implementation of open innovation. The study was approached with a qualitative and interpretive method. Secondary sources were used exclusively to review the practical aspects of open innovation in theory and practice. Open innovation practice at Nokia Corp. and the Procter & Gamble Company were researched and reported using studies of other authors as well as the companies’ own publications. The classification of open innovation practices in contemporary literature is not sufficient to provide an understanding for the various types of open innovation practices that can be applied and used in practice. A classification based on types of activities is presented by the authors, and practical suggestions regarding design and implementation concludes the thesis.

The following study tried to reveal and comprehend educational practicals in families that live in a lower class neighborhood in Sao Paulo city. Revealing the senses of educational practicals of these families, it has been, firstly, entering their worlds, contextualize their living experiences, and in order to do that, it has been important and revealing get to know their particulars, because the intention of this research has not been only to generalize the senses of the familiar educational practicals. The sense can be comprehended in this work, like the path where these practicals point, it means, the direction of the configured practicals from the narrative obtained from the interviewed families. It s important to remember that, the sense appear according to the situation, which means, within space and time, within a determined context or season, therefore what has emerged from this research refers to investigation that has taken place. This is an existential qualitative phenomenological research. As part of this study we have two families from EMEF s students of the neighborhood. These two families have taken two meetings where reflexive interviews were made, according to Szymanki proposal, besides the testimonies taken in group meetings. The data analysis was inspired on the Existential Phenomenology that was applied to get the educational practicals from their speeches. The results achieved point that the educational practicals of the studied families reveal the sense of being a father and a mother and take the role of being the educators of their own children, leading them to a better life. We haven t noticed a dialogic practical, but a command respect-obedience relationship, although this image of a educator family, committed in their children education, most of the times do not adequate to the concept that some educators have about lower-class families
O presente estudo procurou desvelar e compreender sentidos de práticas educativas de famílias moradoras de um bairro de baixa renda no município de São Paulo. Desvelar sentidos de práticas educativas dessas famílias foi primeiramente adentrar em seus mundos, contextualizar suas vivências e para isso foi importante e relevante conhecer e considerar suas peculiaridades, pois a intenção dessa pesquisa não foi generalizar os sentidos de práticas educativas familiares. O sentido é compreendido nesse trabalho, como o caminho para onde apontam tais práticas, ou seja, o rumo e a direção das práticas configuradas a partir das narrativas obtidas pelas entrevistas com essas famílias. É importante lembrar que sentido dá-se em situação, isto é, num espaço e tempo, num determinado contexto ou época, portanto o que emergiu nesse trabalho foi referido à investigação que aqui se realizou. Trata-se de uma pesquisa qualitativa de base fenomenológica existencial. Participaram do estudo duas famílias de alunos de uma EMEF da região onde moram. Com essas famílias foram feitos dois encontros para a realização de entrevistas reflexivas, segundo a proposta de Szymanski, além dos depoimentos coletados em reuniões coletivas. A análise dos dados inspirou-se na Fenomenologia Existencial de cunho hermenêutico para se desvelar os sentidos das práticas educativas no discurso dessas famílias. Os resultados alcançados apontam que as práticas educativas das famílias estudadas revelam um sentido que expressa a responsabilidade de ser pai e mãe e de assumirem o papel de educadores de seus filhos, instrumentando-os para uma vida melhor. Não observamos uma prática dialógica, mas de imposição e obediência, porém essa imagem de família educadora e comprometida na educação dos filhos, muitas vezes não se adequa ao conceito que alguns educadores têm sobre as famílias de classes populares

Full textAbstract:
Normal human limitations mean that when people decide how to act, they often have to base their decisions on flawed information or reasoning. Even when agents reason to the best of their ability, and form intentions consistent with that reasoning, they sometimes get things wrong. Dominant theories about reasons for action argue that all good, or ‘normative’, reasons for acting are objective normative reasons. But objective normative reasons for action are derived from facts about the world that ignore certain facts about human agents. On these accounts of reasons, real human agents can be unable to learn what they have normative reason to do. A common response to this problem is to say that in such situations people act in a praiseworthy way, but their actions are based on false beliefs, and false beliefs cannot be good reasons. I argue that when agents reason to the best of their ability and form intentions consistent with that reasoning, agents act appropriately in response to states of the world that are normative reasons for action. To support my claim, I develop an account of what I call ‘justifiable reasons’, normative reasons for action that human agents can always use as a basis for action, and the form of reason that underpins rationality.
I discuss the similarities and differences between my account of justifiable reasons and several approaches to reasons that resemble my account. I show that, in spite of objections, justifiable reasons are normative reasons, not motivating reasons. Accounts of subjective normative reasons are based on examples that look similar to mine. So, I explain why justifiable reasons are not subjective normative reasons. Some features of internal reasons also resemble features of justifiable reasons. But, I show that there is nothing about justifiable reasons that entails that they must be internal or external reasons. I take it that justifiable and objective normative reasons serve different purposes, so I explain these different purposes. Finally, I argue in support of my claim that to be rational, agents must act appropriately in response to justifiable reasons.

Full textAbstract:
This dissertation is a collection of poems preceded by a critical preface. The preface considers Anthony’s Hecht’s long poem, “The Venetian Vespers,” and the ways in which the temporally unsettled situation of the poem’s speaker parallels a problem facing narrative-meditative poets. The preface is divided into two main sections that explore divisions of this larger conflict. The first discusses the origins and effects of the speaker’s uprootedness in time, and the ways in which he tries to both combat and embrace this dislocation by temporarily losing himself in the immediacy of observing visual art. In this section I connect the dilemma of the speaker, who wishes to escape his memory by focusing outwards, to the dilemma of a representational poet who, despite his position towards the past, must necessarily confront or recollect memories and emotions in order to create authentic descriptions or characters. The second section focuses on the production and appreciation of artistic works (both visual and literary) and how the meaning, production and appreciation of beauty are inseparable from its existence within the physical limits of time. Here I discuss the significance of Hecht’s character who is surrounded with beauty yet describes himself as a person who only observes and does not create anything. Through this character, I argue that Hecht reveals a fundamental conflict that exists between artistic creation and chronological time, and that his poem embodies a particular and paradoxical view of beauty that resonates deeply with the motivations and struggles of writing poems.

A study of material and a case study on the implementation of the system at Amatola District Council is described. The performance management model designed by Good People Management has been applied and described in the text. The research results indicate that the majority of staff supports and understand the process. However, feedback and the attitudes of female employees thereof are highlighting red signals. This creates a completely new area of research of which the writer is only highlighting the issue for further research. Linking of performance management with compensation comes up as an issue, understandably so because the Council has agreed not to link the two processes. Recommendations on how to improve the system have been put forward.

Full textAbstract:
Mutual-exclusion locks are currently the most popular mechanism for interprocess synchronisation, largely due to their apparent simplicity and ease of implementation. In the parallel-computing environments that are increasingly commonplace in high-performance applications, this simplicity is deceptive: mutual exclusion does not scale well with large numbers of locks and many concurrent threads of execution. Highly-concurrent access to shared data demands a sophisticated 'fine-grained' locking strategy to avoid serialising non-conflicting operations. Such strategies are hard to design correctly and with good performance because they can harbour problems such as deadlock, priority inversion and convoying. Lock manipulations may also degrade the performance of cache-coherent multiprocessor systems by causing coherency conflicts and increased interconnect traffic, even when the lock protects read-only data. In looking for solutions to these problems, interest has developed in lock-free data structures. By eschewing mutual exclusion it is hoped that more efficient and robust systems can be built. Unfortunately the current reality is that most lock-free algorithms are complex, slow and impractical. In this dissertation I address these concerns by introducing and evaluating practical abstractions and data structures which facilitate the development of large-scale lock-free systems. Firstly, I present an implementation of two useful abstractions which make it easier to develop arbitrary lock-free data structures. Although these abstractions have been described in previous work, my designs are the first that can be practically implemented on current multiprocessor systems. Secondly, I present a suite of novel lock-free search structures. This is interesting not only because of the fundamental importance of searching in computer science and its wide use in real systems, but also because it demonstrates the implementation issues that arise when using the practical abstractions I have developed. Finally, I evaluate each of my designs and compare them with existing lock-based and lock-free alternatives. To ensure the strongest possible competition, several of the lock-based alternatives are significant improvements on the best-known solutions in the literature. These results demonstrate that it is possible to build useful data structures with all the perceived benefits of lock-freedom and with performance better than sophisticated lock-based designs. Furthermore, and contrary to popular belief, this work shows that existing hardware primitives are sufficient to build practical lock-free implementations of complex data structures.

Full textAbstract:
In this dissertation, I argue for what I call “practical perspective compatibilism”. According to this thesis, an agent with practical freedom is sufficiently free to be a moral agent and morally responsible for his or her actions. The concept of practical freedom is originally found in the writings of Kant. Kant argued that we can view the world from either a theoretical or a practical perspective. The theoretical perspective is that of causal explanation and prediction, whereas the practical perspective is that of choosing what to do and how to act. We see that we are free when we view things from a practical perspective. Determinism cannot threaten our practical freedom, since from a practical perspective we must choose what to do even if everything ultimately is determined. I argue that practical freedom is sufficient freedom-wise for moral agency and moral responsibility because morality is action-guiding. Right and wrong are concepts to be employed in deliberation and advice. This is a strong reason to regard factors irrelevant to deliberators and advisers as irrelevant when making judgements of right and wrong, and whether somebody had some other kind of freedom than practical freedom is irrelevant to deliberators and advisers. There are also prima facie reasons to regard moral responsibility as tied to rightness and wrongness, so that agents are blameworthy when they did wrong (or subjectively wrong, or what would have been wrong given their state of information and so on) and praiseworthy when they did right (subjectively right and so on). I also show that no classic arguments for incompatibilism about determinism and moral responsibility work when directed against practical perspective compatibilism. Finally, this thesis discusses metaethics in relation to compatibilism. Since competing theories imply the falsity of some respected metaethical positions, metaethical considerations lend further support to practical perspective compatibilism.I den här avhandlingen argumenterar jag för en tes som jag kallar “praktisk-perspektiv-kompatibilism”. Enligt praktisk-perspektiv-kompatibilism är det så att en agent med praktisk frihet är tillräckligt fri för att vara en moralisk agent och moraliskt ansvarig. Praktisk frihet är ett koncept vi ursprungligen hittar hos Kant. Det används också av en del nutida Kantianer. Kant argumenterade för att vi kan betrakta världen från antingen ett praktiskt eller ett teoretiskt perspektiv. Det teoretiska perspektivet är det vi har när vi gör förutsägelser och hittar kausala förklaringar, medan det praktiska är det vi har när vi väljer och handlar. Vi kan se att vi är fria när vi ser på tillvaron ur det praktiska perspektivet. Determinismen kan inte hota vår praktiska frihet, för vi måste välja våra handlingar oavsett om allting i slutändan är determinerat. I denna avhandling definierar jag praktisk frihet på följande sätt: En agent har minimal praktisk frihet om och endast om han måste välja sina handlingar, och han tror att hans vilja är effektiv när det gäller att realisera de handlingsalternativ han funderat över och väljer mellan. En agent har maximal praktisk frihet om och endast om han har minimal praktisk frihet, hans vilja verkligen är effektiv, han har full information om de alternativ han funderar över, och alla alternativ han inte tänkt på är sådana att hans egna värderingar inte ger honom ett övervägande skäl att välja ett av dessa alternativ snarare än det han faktiskt väljer. Jag argumenterar för att praktisk frihet så definierat är tillräckligt med frihet för moraliskt agentskap och moraliskt ansvar eftersom moralen är handlingsvägledande. Det betyder att rätt och fel är koncept som ska användas i övervägning av olika handlingsalternativ och rådgivning. Tredje-persons-omdömen om ifall någon handlade rätt eller fel måste vara sådana att de hypotetiskt sett skulle kunna fungera som råd; egenskapen att vara rätt eller fel kan inte förändras beroende på om vi ger råd eller bara faller omdömen. Detta är ett starkt skäl för att betrakta faktorer som är irrelevanta för övervägare och rådgivare som irrelevanta när man faller omdömen om rätt och fel, och ifall någon hade en annan sorts frihet än den praktiska är irrelevant för övervägare och rådgivare. Vi har också prima facie skäl att betrakta moraliskt ansvar som knutet till rätt och fel, så att agenter är klandervärda när de gjorde fel (eller subjektivt fel, eller vad som skulle ha varit fel givet den information agenten hade osv) och berömvärda när de gjorde rätt (subjektivt rätt osv). Att det finns prima facie skäl för att betrakta praktisk frihet som tillräckligt för moraliskt ansvar utesluter förstås inte att det finns övervägande skäl för den motsatta ståndpunkten. Jag visar dock att inga klassiska argument för inkompatibilism om determinism och moraliskt ansvar fungerar när man riktar dem mot praktisk-perpsektiv-kompatibilism. Alla sådana argument förutsätter vad som skulle bevisas, nämligen att faktorer som är irrelevanta för övervägare och rådgivare är moraliskt relevanta, och att pålitliga moraliska intuitioner uppstår när vi betraktar agenter från ett teoretiskt snarare än praktiskt perspektiv. Slutligen diskuterar denna avhandling relationen mellan metaetik och kompatibilism. Praktisk-perspektiv-kompatibilism är kompatibel med samtliga metaetiska teorier, medan det finns flera metaetiska teorier som implicerar att inkompatibilismen är falsk, och åtminstone en som implicerar att vissa kompatibilistiska teorier också är falska. Enligt en speciell Kantiansk konstruktivistisk teori så finns det rätt- och felaktiga handlingar och moraliskt ansvar på grund av att det finns praktisk frihet. Om detta är den sanna metaetiska teorin, så följer det att praktisk frihet är tillräckligt för moraliskt agentskap och moraliskt ansvar, och att inte bara inkompatibilism men andra kompatibilistiska teorier också är falska. Beroende på vilken metaetisk teori som är den sanna, kan det alltså vara så att de föregående argumenten är överflödiga för att bevisa praktisk-perspektiv-kompatibilism. Det kan vara så att denna tes helt enkelt följer från den sanna metaetiska teorin.

Legal and regulatory changes have made the 1981 edition of the Practical Comptrollership Course (PCC) Textbook obsolete. A new PCC Textbook was drafted under the hypothesis that it could be rewritten to improve the future performance of the military comptroller better than the 1981 edition. The hypothesis was tested by having a comptroller, a senior officer, an accounting professional, and several auditors compare the new PCC Textbook with the 1981 version, and their paradigms for comptrollership to determine if the new PCC Textbook might prepare comptrollers better. Research revealed that some characteristics of the new PCC Textbook were more likely to improve future comptrollership. Further, the research revealed differences in expectations between the accounting professional and the senior officer. Suggestions for improved research methods and salient topics for further research are offered. The new PCC Textbook is appended to the thesis

The design and use of expert systems for medical diagnosis remains an attractive goal. One such system, the Quick Medical Reference, Decision Theoretic (QMR-DT), is based on a Bayesian network. This very large-scale network models the appearance and manifestation of disease and has approximately 600 unobservable nodes and 4000 observable nodes that represent, respectively, the presence and measurable manifestation of disease in a patient. Exact inference of posterior distributions over the disease nodes is extremely intractable using generic algorithms. Inference can be made much more efficient by exploiting the QMR-DT's unique structure. Indeed, tailor-made inference algorithms for the QMR-DT efficiently generate exact disease posterior marginals for some diagnostic problems and accurate approximate posteriors for others. In this thesis, I identify a risk with using the QMR-DT disease posteriors for medical diagnosis. Specifically, I show that patients and physicians conspire to preferentially report findings that suggest the presence of disease. Because the QMR-DT does not contain an explicit model of this reporting bias, its disease posteriors may not be useful for diagnosis. Correcting these posteriors requires augmenting the QMR-DT with additional variables and dependencies that model the diagnostic procedure. I introduce the diagnostic QMR-DT (dQMR-DT), a Bayesian network containing both the QMR-DT and a simple model of the diagnostic procedure. Using diagnostic problems sampled from the dQMR-DT, I show the danger of doing diagnosis using disease posteriors from the unaugmented QMR-DT.
(cont.) I introduce a new class of approximate inference methods, based on feed-forward neural networks, for both the QMR-DT and the dQMR-DT. I show that these methods, recognition models, generate accurate approximate posteriors on the QMR-DT, on the dQMR-DT, and on a version of the dQMR-DT specified only indirectly through a set of presolved diagnostic problems.

Joint practical deliberation is the activity of deciding together what to do. In this dissertation, I argue that several speech acts that we can use to alter our moral obligations - promises, offers, requests, demands, commands, and agreements - are moves within joint practical deliberation. The dissertation begins by investigating joint practical deliberation. The resulting account implies that joint deliberation is more flexible than we usually recognize, in two ways. First, we can make joint decisions not only about what we will do together, but also about what you or I will do alone. Second, we can deliberate by means of two distinct methods: propose-and-ratify, in which a proposed joint decision must be explicitly accepted to come into effect, and propose-and-challenge, in which a proposed joint decision comes into force unless it is explicitly challenged. Varying these parameters generates a botany of different kinds of proposals we can make within joint deliberation. When we look at these proposals more closely, we make a surprising discovery: for each kind of proposal we can make in joint practical deliberation, there is an everyday speech act with the very same properties. A certain kind of proposal to make a joint decision regarding one's own actions has the same normative effects, under the same conditions, as a promise. One kind of proposal to make a joint decision regarding one's addressee's actions has all the essential features of a command; another kind of deliberative proposal - with the same content but a different method of evaluation - looks exactly like a request. And so on. These similarities are too systematic to be coincidental. The only explanation, I argue, is that these ordinary speech acts are identical to their doppelgangers within joint practical deliberation. Promises and offers are proposals to make joint decisions about what I will do. Commands, demands, and requests are proposals to make joint decisions about whatyou will do. And agreements are joint decisions about what we will do. Call this the deliberative theory of these speech acts. Considering each speech act in turn, I defend the deliberative theory by arguing that it provides a uniquely powerful explanation of its targets' social and moral significance. Once we see how naturally these speech acts fall out of our practice of joint deliberation, theories that treat them as sui genens - as many moral philosophers now do - will come to seem redundant and nonexplanatory. Conversely, thinking of promises, offers, commands, demands, requests, and agreements as moves within joint practical deliberation allows us to give an elegant and generative theory of these phenomena that have confounded moral philosophers for so long.

A high resolution reconfigurable mold has been sought after for over 150 years. An ideal reconfigurable mold would be capable of producing detailed surfaces for use in molding and be capable of fast surface reconfiguration. Such a device would combine the fast speed and repeatability of formative processes, like injection molding, with the flexibility of additive processes, like 3D printing. An affordable, high resolution, reconfigurable mold could be a practical tool for a lean, short-run shop or factory, serving as a resin mold, fixturing surface or concrete formwork; to name only a few possible applications. Resembling the common pin art toy, a discrete element pin bed has often been proposed as a design for a reconfigurable mold. Conventional actuation strategies are often cumbersome and expensive, due to the quadratic increase in number of pin elements with increasing surface resolution. Very few designs exist that are capable of producing a reconfigurable pin array at sufficiently high resolution to compete with the cost of making a fixed geometry mold. A practical pin tool, an inexpensive but high resolution molding tool, could be an asset to shops and small business everywhere, but nothing like this currently exists. This thesis presents a concise design strategy, backed up by analytical arguments and empirical evidence which can used to construct an affordable, high resolution reconfigurable pin tool. We address the challenge of quadratic scaling by edge-addressing simple, nonlinear mechanisms to actuate each pin. Edge addressing, along rows and columns of pins, reduces the number of control inputs to a small, linearly increasing value. Nonlinear mechanisms at each discrete pin site allow for a predictable, localized expression of the edge addressed inputs. Two embodiments of this design strategy are proposed and tested. First, a diode/resistive heater array allows for electrical edge addressing and control of a fusible alloy brake to grip or release targeted, sliding pins. Second, an array of screws is edge addressed by mechanical oscillations to generate nonlinear tangential forces in targeted screws, resulting in controllable screw translations. We conclude by summarizing our results and discuss directions for future work.

Full textAbstract:
This essay is one part of my Bachelor's degree project, the other part being a dance performance with the title practical, efficient, necessary that was premiered in January of 2021. The essay discusses the main problem of the project (which was necessary movements and the lack thereof in dance) as for thoughts and methods that was used in the project in working with the theme of necessity. The essay begins by looking into movements of necessity from the perspective of a necessary movement being a practical movement that is in relation to survival and sprung out of urgency. It further explores necessary movements from the martial arts-perspective, and more specifically Muay Thai. The essay touches upon subjects such as the nervous system and the stress response as for preparatory movements as long term responses to urgency, while also looking into body-mind split theories. The essay also discusses protests as a method of self-defence, referring to artist and activist Rodney Diverlus analysis of the movements used in Black Lives Matter demonstrations. The main reference and conversation partner to many of the topics discussed in the essay is Pragmatist philosopher John Dewey and his thoughts in Art as Experience (1932) and Experience and Nature (1925). Further the essay describes the various methods used in the process of making the performance such as 'systematic choreographing' and 'temporary truths'. This allowed for further explorations of topics in the essay such as the starting and ending of movements, the power of repetition and sounds as necessity. The essay ends with reflections and refiguring of the concept of necessary movements.This work includes both a performing and a written part.

Full textAbstract:
The physical limitations of uniprocessors and the real-time requirements of numerous practical applications have made parallel processing an essential technology in military, industry and scientific research. In this dissertation, we investigate parallelizations of three practical applications using three parallel machine models. The algorithms are:
Finitely inductive (FI) sequence processing is a pattern recognition technique used in many fields. We first propose four parallel FI algorithms on the EREW PRAM. The time complexity of the parallel factoring and following by bucket packing is O(sk^2 n/p), and they are optimal under some conditions. The parallel factoring and following by hashing requires O(sk^2 n/p) time when uniform hash functions are used and log(p) ≤ k n/p and pm ≈ n. Their speedup is proportional to the number processors used. For these results, s is the number of levels, k is the size of the antecedents and n is the length of the input sequence and p is the number of processors.
We also describe algorithms for raster/vector conversion based on the scan model to handle block-like connected components of arbitrary geometrical shapes with multi-level nested dough nuts for the IES (image exploitation system). Both the parallel raster-to-vector algorithm and parallel vector-to-raster algorithm require O(log(n2)) or O(log2(n2)) time (depending on the sorting algorithms used) for images of size n2 using p = n2 processors.
Not only is the DWT (discrete wavelet transforms) useful in data compression, but also has it potentials in signal processing, image processing, and graphics. Therefore, it is of great importance to investigate efficient parallelizations of the wavelet transforms. The time complexity of the parallel forward DWT on the parallel virtual machine with linear processor organization is O(((so+s1)mn)/p), where s0 and s1 are the lengths of the filters and p is the number of processors used. The time complexity of the inverse DWT is also O(((so+s1)mn)/p). If the processors are organized as a 2D array with PrawPcol processors, both the interleaved parallel DWT and IDWT have the time complexity of O(((so+s1)mn)/ProwPcol).
We have parallelized three applications and achieved optimality or best-possible performances for each of the three applications over each of the chosen machine models. Future research will involve continued examination of parallel architectures for implementation of practical problems.

Full textAbstract:
The demand of an increasingly networked world is well reflected in modern industrial control systems where communication between the different components of the system is more and more taking place over a network. With an increasing number of components communicating and with hardware devices of low complexity, the communication resources available per communication link are however very limited. Yet, despite limited resources, the control signals transmitted over the link are still required to meet strict real-time and reliability constraints. This requires entirely new approaches in the intersection of communication and control theory. In this thesis we consider the problem of stabilizing an unstable linear-quadratic-Gaussian (LQG) plant when the communication link between the observer and the controller of the plant is noisy. Protecting the data transmitted between these components against transmission errors by using error control schemes is essential in this context and the main subject to this thesis. We propose novel error-correcting codes, so-called anytime codes, for this purpose and show that they asymptotically fulfill the reliability requirements known from theory when used for transmission over the binary erasure channel (BEC). We identify fundamental problems when the messages to be transmitted are very short and/or the communication channel quality is very low. We propose a combinatorial finite-length analysis which allows us to identify important parameters for a proper design of anytime codes. Various modifications of the basic code structure are explored, demonstrating the flexibility of the codes and the capability of the codes to be adapted to different practical constraints. To cope with communication channels of low quality, different feedback protocols are proposed for the BEC and the AWGN channel that together with the error-correcting codes ensure the reliability constraints at short delays even for very short message lengths. In the last part of this thesis, we integrate the proposed anytime codes in an automatic control setup. We specify the different components necessary for this and determine the control cost when controlling an unstable LQG plant over a BEC using either the anytime codes proposed in this thesis or block codes. We detail the relation between parameters such as channel quality, code rate, plant instability and resources available and highlight the advantage of using anytime codes in this context.Throughout the thesis, the performance of the anytime codes is evaluated using asymptotic analysis, finite-length analysis and/or simulation results.QC 20160422

Full textAbstract:
This study addresses research reporting practices and protocols by bridging the gap from the theoretical and conceptual debates typically found in the literature with more realistic applications using data from published research. Specifically, the practice of using findings of statistical analysis as the primary, and often only, basis for results and conclusions of research is investigated through computing effect size and confidence intervals and considering how their use might impact the strength of inferences and conclusions reported.
Using a sample of published manuscripts from three peer-rviewed journals, central quantitative findings were expressed as dichotomous hypothesis test results, point estimates of effect sizes and confidence intervals. Studies using three different types of statistical analyses were considered for inclusion: t-tests, regression, and Analysis of Variance (ANOVA). The differences in the substantive interpretations of results from these accomplished and published studies were then examined as a function of these different analytical approaches. Both quantitative and qualitative techniques were used to examine the findings. General descriptive statistical techniques were employed to capture the magnitude of studies and analyses that might have different interpretations if althernative methods of reporting findings were used in addition to traditional tests of statistical signficance. Qualitative methods were then used to gain a sense of the impact on the wording used in the research conclusions of these other forms of reporting findings. It was discovered that tests of non-signficant results were more prone to need evidence of effect size than those of significant results. Regardless of tests of significance, the addition of information from confidence intervals tended to heavily impact the findings resulting from signficance tests.
The results were interpreted in terms of improving the reporting practices in applied research. Issues that were noted in this study relevant to the primary focus are discussed in general with implicaitons for future research. Recommendations are made regarding editorial and publishing practices, both for primary researchers and editors.

Thesis (DTh)--Stellenbosch University, 2012.ENGLISH ABSTRACT: This dissertation has sought to examine how a post-foundationalist approach to Practical Theology might look. This was done through a critical appraisal of the paradigms of foundationalism and non-foundationalism. These paradigms were explored in their historical context and development to illustrate the defining differences and features of both. The researcher then explored Practical Theology in its historical development to examine whether it has moved beyond foundationalism. This was further done by examining the last three decades of Practical Theology by a comparison of methodologies currently proposed. It emerged that, in many ways, Practical Theology has moved beyond the paradigm of foundationalism. This was seen in its affirmation of the local context, its use of a correlational hermeneutic and the pastoral cycle. These areas were then fleshed out in further detail in an attempt to delineate a truly non-foundationalist Practical Theology. A missional perspective on Practical Theology became an entry point into detailed discussions with regard to context, as well as to how the various sources of the correlational hermeneutic can best be understood in a post-foundationalist world, in light of the post-modern critique. These unique features are indeed central to a post-foundational approach to doing Practical Theology.
AFRIKAANSE OPSOMMING: Hierdie proefskrif het gepoog om na te vors hoe ʼn post-foundationalistic benadering tot Praktiese Teologie daar sou uitsien. Dit behels ʼn kritiese beoordeling van die foundationalism en nie-foundationalism paradigmas. Hierdie paradigmas is in hul historiese konteks en ontwikkeling ondersoek om die bepalende verskille en kenmerke van albei te illustreer. Daarna het die navorser Praktiese Teologie in sy historiese ontwikkeling ondersoek om vas te stel of dit verby foundationalism beweeg het. Dit is gedoen deur na die laaste drie dekades van Praktiese Teologie se ontwikkeling te kyk en ʼn vergelyking te tref tussen die verskillende benaderings tot die vak. Dit het geblyk dat Praktiese Teologie in vele opsigte buite die paradigma van foundationalism beweeg het. Dit word duidelik as daar gekyk word na sy bevestiging van die plaaslike konteks, sy gebruik van ʼn korrelasie (correlational) hermeneutiek en die pastorale siklus. Hierdie areas is toe aangevul met verdere detail in ʼn poging om ʼn ware nie-foundationalistic Praktiese Teologie uit te beeld. ʼn Missionale perspektief op Praktiese Teologie het ʼn aansluitingspunt vir uitvoerige besprekings met betrekking tot konteks geword, asook tot hoe die verskeie bronne van die korrelasie hermeneutiek die beste verstaan kan word in ʼn post-foundationalistic wêreld, veral in die lig van die post-moderne kritiek. ʼn Missionale perspektief staan sentraal tot ʼn post-foundational benadering in Praktiese Teologie.

Full textAbstract:
This thesis is an examination of the foundations of practical reason. Building on the later work of Wittgenstein, I argue for a subjectivist view of moral judgment and of judgments about reasons for action. On this view, moral judgments and judgments about reasons for action can be true or false, but they are not objective. The argument for this view has the form of an inference to the best explanation. Using a distinction between primary and secondary qualities, I suggest that moral judgments and judgments about reasons for action should not be construed as referring to an ethical or normative reality that exists independently of us. There are ethical facts and facts about our reasons, but these facts arise as the result of our involvement in a linguistic practice. This provides a new way of accounting for these judgments that differs both from moral realism and expressivism. The view of reasons that emerges is closely related to, but not identical with, reasons internalism as described by Bernard Williams. I reject his argument in favour of internalism and provide a new and independent argument to support this view of our reasons. In the course of spelling out that argument, I show why internalism as described by Williams should be modified, and why this does not commit us to externalism. In the final chapters, I show that there is an important parallel between our practical predicament and the account of our epistemic condition as portrayed by Wittgenstein. The inference to the best explanation is completed by considering a number of objections to subjectivism that are based on the idea that a subjectivist account of moral judgment and of reasons fails to do justice to the ethical phenomena. I reject these objections, and suggest that a subjectivist can both be reflectively aware of his subjectivism and continue to live well.

Full textAbstract:
In this thesis I aim to answer two questions: Are alternatives for choice ever incomparable? and, In what ways can items be compared? I argue that there is no incomparability among bearers of value and that the ways in which items can be compared are richer and more varied than commonly supposed. The two questions are closely related; in arguing against incomparability a positive picture of comparability emerges. The case against incomparability is a case for a new conception of comparability more capacious than has been traditionally conceived. This 'broad' conception of comparability has three distinctive features: it distinguishes incomparability from noncomparability, it includes the possibility of 'emphatic' comparability, or comparisons between 'higher' and 'lower' goods; and it makes logical space for a fourth generic value relation - what I shall call 'on a par' - beyond the standard trichotomy of relations of 'better than', 'worse than', and 'equally good'. Each of these features arises out of defects of certain incomparabilist arguments. Indeed, the approach to the broad conception of comparability via examination of incomparabilist arguments makes clear that much of the intuitive pull of incomparability depends on a narrow and impoverished conception of comparability. Investigation of comparability and incomparability is motivated by a proposed substantive account of practical justification according to which there can be no justified choice without the comparability of the alternatives. The existence of widespread incomparability, then, undermines the rationality of practical life. This thesis' argument against incomparability and for a broad conception of comparability serves to vindicate the role of practical reason in choice.

The thesis is an exploration of the relations between know-how, abilities, and ordinary knowledge of facts. It is shown that there is a distinctively practical sort of know-how and a corresponding interpretation of 'S knows how to [phi]', and that this special sort of know-how, while possessing representational content, is not simply ordinary knowledge-that. The view rests on a novel distinction between two interpretations of the Intellectualist slogan, familiar from the work of Gilbert Ryle, that know-how is a kind of knowledge-that. The distinction allows us to clarify the issues that are at stake in the debate and see the possibility of a position that combines aspects of both Intellectualism and anti-Intellectualism. An entailment from knowhow to a certain sort of ability is defended, and it is shown that the present view preserves the possibility of appealing to know-how to block Frank Jackson's "knowledge argument" against physicalism.

Full textAbstract:
The ability to measure tiny variations in the local gravitational acceleration allows – amongst other applications – the detection of hidden hydrocarbon reserves, magma build-up before volcanic eruptions, and subterranean tunnels. Several technologies are available that achieve the sensitivities required (tens of μGal/√Hz), and stabilities required (periods of days to weeks) for such applications: free-fall gravimeters, spring-based gravimeters, superconducting gravimeters, and atom interferometers. All of these devices can observe the Earth tides; the elastic deformation of the Earth’s crust as a result of tidal forces. This is a universally predictable gravitational signal that requires both high sensitivity and high stability over timescales of several days to measure. All present gravimeters, however, have limitations of excessive cost (£70 k) and high mass (<8 kg). In this thesis, the building of a microelectromechanical system (MEMS) gravimeter with a sensitivity of 40 μGal/√Hz in a package size of only a few cubic centimetres is discussed. MEMS accelerometers – found in most smart phones – can be mass-produced remarkably cheaply, but most are not sensitive enough, and none have been stable enough to be called a ‘gravimeter’. The remarkable stability and sensitivity of the device is demonstrated with a measurement of the Earth tides. Such a measurement has never been undertaken with a MEMS device, and proves the long term stability of the instrument compared to any other MEMS device, making it the first MEMS accelerometer that can be classed as a gravimeter. This heralds a transformative step in MEMS accelerometer technology. Due to their small size and low cost, MEMS gravimeters could create a new paradigm in gravity mapping: exploration surveys could be carried out with drones instead of low-flying aircraft; they could be used for distributed land surveys in exploration settings, for the monitoring of volcanoes; or built into multi-pixel density contrast imaging arrays.

International Telemetering Conference Proceedings / October 17-20, 1988 / Riviera Hotel, Las Vegas, NevadaWith more complex vehicle designs, the frequency and number of measurements contained in telemetry data streams has dramatically increased. One way of improving the use of bandwidth is to change the sample rate, quantity, or type of measurements dynamically. A telemetry front end must be programmable to handle different formats. In a front end that decommutates and routes measurements, a decom list is a control program, which defines the location, size, orientation, and identity of the measurements. To deal with dynamic format changes, a telemetry front end must be able to switch between decom lists. A practical approach to decom list switching must address the needs of error avoidance, packet switching, and the location of switching keys in any portion of the format. Switching between formats should not be restricted to a preprogrammed sequence, but should allow multiple destinations from a particular decom list. A practical and flexible implementation of decom list switching is detailed along with an explanation of how this implementation solves a variety of decommutation problems.

Full textAbstract:
This thesis explores television practices in a time when new technology has made it possible to interact with and create your own TV content. The work is focused on how user practices need to be understood in a context of chan- ging technology. The practices studied also show the relevance of ethno- graphic methods, and especially the wide spectrum of these different meth- ods within the field of Human-Computer Interaction. We distinguish be- tween sociologically informed ethnography and anthropological ethnogra- phy. Two questions are addressed: how can new forms of television practices be understood by means of different ethnographic methods, and, on a wider level, what method can we use for analysing methods in ethnographic re- search? Because ethnographic methods are qualitative, we have also chosen to use an open and qualitative approach when analysing them. Through comparing our different methods – their data and findings on one specific topic – we have discovered the differences between the methodological ap- proaches.
