The concept of game development has traditionally not implemented the skills of professional writers to develop the scripts for a computer game. However, due to the growth in complexity and size of the computer game development process, as well as the growing teams of people involved in the development of computer games, the need to employ skilled writers has emerged in modern computer game development. It has, however, become clear that the role of the writer within the collaborative game development process is still ill-defined. And therefore, the writer who wishes to start writing for the games industry, is faced with a great deal of obstacles. It was therefore deemed necessary to develop a script development model for the creation of computer games that can assist the writer of a computer game by means of thorough guidance. The aim of this research project is therefore to develop such a model. The first step towards the establishment of a script development model, would be to determine the position of the writer in the collaborative game production communication process. In order to establish this, a communication model was developed for the communication process of the computer game development process, based on Roman Jakobson's communication model. After the position of the writer in the communication process was established, a game development model was developed to determine the position of the writer within the entire game development process. This was done so that the functions and responsibilities of the writer - within a greater collaborative development process - could be determined. This model was developed based on existing software development models, as well as two different models from the games industry that focus on different aspects within the game development process. With the position, functions and responsibilities of the writer determined, it was possible to postulate a script development model for the creation of computer games. This model was developed with an emphasis on the game context, creative strategies and analytical frameworks available to the writer. Furthermore guidelines were provided on the actual scripting of the computer game script, based on elements from drama theory. To test the script development model, a non-functional prototype (thin-slice) computer game script was developed based on the Fritz Deelman-series (Leon Rousseau). The script development model was used as guideline to establish whether the script development model could in future be used to develop a full-scale, implementable computer game script. / Thesis (M.A. (Afrikaans and Dutch))--North-West University, Potchefstroom Campus, 2008.

In the context of a society were the Web is present in many aspects, there is asignificant amount of visually impaired users whose experience is far from beingsatisfactory. There are technologies aiming this problem but still with no full suc-cess. The problem addressed in this project is the existing gap between the visuallyimpaired users and the solutions being offered to them. As a solution to this problem,a middleware prototype is developed. It acts as a web application so the user doesnot need to install anything. The middleware also offers different adaptations to theuser such as amplifying lens, text narrator, and others. The solution was tested byvisually impaired users and it received an overall positive result. Some features likethe amplifying lens received a good value and some of them need further improve-ment.

Plans do not serve the particular circumstances of a given situation, but rather serve as abstract descriptions of some future activities. The relationship between plans, which are abstract, and actions, which are concrete, is referred to as the relationship between plans and situated actions. This relationship can be formulated in the following questions: 1) How do individuals conceive of future activities? 2) How does an individual who is acting upon a plan adjust when facing contingencies? The relationship between plans and situated actions has remained a source of intense academic discussions (e.g., Bardram, 1997; Bardram & Hensen, 2010; Leudar & Costall, 1996; Ng, 2002; Schmidt, 1997; Suchman, 1987). Despite the ample research on the relationship between plans and situated actions, a review of the literature indicates that the problem has not been adequately addressed (Randall et al., 2007; Suchman 2003), which has compelled this researcher to create a theoretical model that integrates the disparate nature of plans and line of actions. Drawing on research on cognition and categorization theory, this thesis proposes a theoretical framework that conceptualizes the relationship between plans and situated actions in terms of activity categories. Specifically, the theoretical framework draws on the prototype and basic-level category theories of categorization, both of which were developed primarily by Rosch (1978), as well as the field theory developed by Lewin (1936). Categorization theories are used to address plans’ abstractness as they capture typifications of human experience. Field theory is used to address the concreteness of action as it captures dynamic properties of the situation in the here and now. The basic premise of the theoretical framework is that individuals conceive (have a knowledge) of plans and their attributes as future activity categories with a range of possibilities. These possibilities are structurally graded, ranging from highly typical to atypical. Plans are believed to be formed based on what is typical for the activity. The theoretical framework argues that an association exists between an individual’s knowledge of typical adjustment relevant to the activity and actual adjustment the individual makes while performing the activity. With this in mind, the theoretical framework considers the actor’s perspective to be central to the investigation. Based on the theoretical framework, several hypotheses are formularized and tested. An in-depth case study conducted in a ready-mix concrete company was used to examine aspects of the theoretical framework empirically. The results of the case study provide a wide range of independent evidence supporting the framework. In addition, an experimental methodology was developed for quantitative testing in the laboratory aspects of the theoretical framework not attainable in the case study. Theoretical and practical implications of the proposed framework and empirical findings are examined. Future research directions are discussed.

The worldwide organ shortage occurs despite people’s positive organ donation attitudes. The discrepancy between attitudes and behaviour is evident in Australia particularly, with widespread public support for organ donation but low donation and communication rates. This problem is compounded further by the paucity of theoretically based research to improve our understanding of people’s organ donation decisions. This program of research contributes to our knowledge of individual decision making processes for three aspects of organ donation: (1) posthumous (upon death) donation, (2) living donation (to a known and unknown recipient), and (3) providing consent for donation by communicating donation wishes on an organ donor consent register (registering) and discussing the donation decision with significant others (discussing). The research program used extended versions of the Theory of Planned Behaviour (TPB) and the Prototype/Willingness Model (PWM), incorporating additional influences (moral norm, self-identity, organ recipient prototypes), to explicate the relationship between people’s positive attitudes and low rates of organ donation behaviours. Adopting the TPB and PWM (and their extensions) as a theoretical basis overcomes several key limitations of the extant organ donation literature including the often atheoretical nature of organ donation research, thefocus on individual difference factors to construct organ donor profiles and the omission of important psychosocial influences (e.g., control perceptions, moral values) that may impact on people’s decision-making in this context. In addition, the use of the TPB and PWM adds further to our understanding of the decision making process for communicating organ donation wishes. Specifically, the extent to which people’s registering and discussing decisions may be explained by a reasoned and/or a reactive decision making pathway is examined (Stage 3) with the novel application of the TPB augmented with the social reaction pathway in the PWM. This program of research was conducted in three discrete stages: a qualitative stage (Stage 1), a quantitative stage with extended models (Stage 2), and a quantitative stage with augmented models (Stage 3). The findings of the research program are reported in nine papers which are presented according to the three aspects of organ donation examined (posthumous donation, living donation, and providing consent for donation by registering or discussing the donation preference). Stage One of the research program comprised qualitative focus groups/interviews with university students and community members (N = 54) (Papers 1 and 2). Drawing broadly on the TPB framework (Paper 1), content analysed responses revealed people’s commonly held beliefs about the advantages and disadvantages (e.g., prolonging/saving life), important people or groups (e.g., family), and barriers and motivators (e.g., a family’s objection to donation), related to living and posthumous organ donation. Guided by a PWM perspective, Paper Two identified people’s commonly held perceptions of organ donors (e.g., altruistic and giving), non-donors (e.g., self-absorbed and unaware), and transplant recipients (e.g., unfortunate, and in some cases responsible/blameworthy for their predicament). Stage Two encompassed quantitative examinations of people’s decision makingfor living (Papers 3 and 4) and posthumous (Paper 5) organ donation, and for registering and discussing donation wishes (Papers 6 to 8) to test extensions to both the TPB and PWM. Comparisons of health students’ (N = 487) motivations and willingness for living related and anonymous donation (Paper 3) revealed that a person’s donor identity, attitude, past blood donation, and knowing a posthumous donor were four common determinants of willingness, with the results highlighting students’ identification as a living donor as an important motive. An extended PWM is presented in Papers Four and Five. University students’ (N = 284) willingness for living related and anonymous donation was tested in Paper Four with attitude, subjective norm, donor prototype similarity, and moral norm (but not donor prototype favourability) predicting students’ willingness to donate organs in both living situations. Students’ and community members’ (N = 471) posthumous organ donation willingness was assessed in Paper Five with attitude, subjective norm, past behaviour, moral norm, self-identity, and prior blood donation all significantly directly predicting posthumous donation willingness, with only an indirect role for organ donor prototype evaluations. The results of two studies examining people’s decisions to register and/or discuss their organ donation wishes are reported in Paper Six. People’s (N = 24) commonly held beliefs about communicating their organ donation wishes were explored initially in a TPB based qualitative elicitation study. The TPB belief determinants of intentions to register and discuss the donation preference were then assessed for people who had not previously communicated their donation wishes (N = 123). Behavioural and normative beliefs were important determinants of registering and discussing intentions; however, control beliefs influenced people’s registering intentions only. Paper Seven represented the first empirical test of the role of organ transplant recipient prototypes (i.e., perceptions of organ transplant recipients) in people’s (N = 465) decisions to register consent for organ donation. Two factors, Substance Use and Responsibility, were identified and Responsibility predicted people’s organ donor registration status. Results demonstrated that unregistered respondents were the most likely to evaluate transplant recipients negatively. Paper Eight established the role of organ donor prototype evaluations, within an extended TPB model, in predicting students’ and community members’ registering (n = 359) and discussing (n = 282) decisions. Results supported the utility of an extended TPB and suggested a role for donor prototype evaluations in predicting people’s discussing intentions only. Strong intentions to discuss donation wishes increased the likelihood that respondents reported discussing their decision 1-month later. Stage Three of the research program comprised an examination of augmented models (Paper 9). A test of the TPB augmented with elements from the social reaction pathway in the PWM, and extensions to these models was conducted to explore whether people’s registering (N = 339) and discussing (N = 315) decisions are explained via a reasoned (intention) and/or social reaction (willingness) pathway. Results suggested that people’s decisions to communicate their organ donation wishes may be better explained via the reasoned pathway, particularly for registering consent; however, discussing also involves reactive elements. Overall, the current research program represents an important step toward clarifying the relationship between people’s positive organ donation attitudes but low rates of organ donation and communication behaviours. Support has been demonstrated for the use of extensions to two complementary theories, the TPB and PWM, which can inform future research aiming to explicate further the organ donation attitude-behaviour relationship. The focus on a range of organ donation behaviours enables the identification of key targets for future interventions encouraging people’s posthumous and living donation decisions, and communication of their organ donation preference.

abstract: This thesis presents a novel, thorough approach to the application of low frequency electromagnetic (EM) wave wireless communication in marine environment. This investigation is both theoretical and experimental, and is oriented towards marine sensor network applications. Different solutions within the underwater low frequency EM communication area are compared on the basis of their feasibility and practicality, especially in relation to scientific environmental monitoring applications. As a result, this thesis gathers a coordinated series of application oriented analyses of devices, such as antennas, transmitters, receivers, and of propagation issues, like signal attenuation and antenna positioning. The concluding step in this analysis is constituted by experimental field tests. As a final outcome, this works provides facts, guidelines and prototype designs related to the application of EM communication in shallow water environment, and demonstrates this communication technique is convenient for shallow water sensor networks implementation. The process followed in this analysis starts from practical considerations regarding the characteristics required by scientific equipment used in environmental monitoring. A case study is presented where a hybrid (partially wired) marine sensor network is deployed in Moreton Bay, Queensland. Strengths and weaknesses of this system are analysed, and, based on this experience, new requirements and constraints are set for a prospective improved fully wireless sensor network. In particular, the shallow water marine environment is recognized as the most likely target for scientific investigation because of its biological, economical and social importance. Firstly, various underwater communication techniques are analysed and compared. This is done on the basis of two factors: the first one is the final use of the sensor network, and the second one is the peculiar nature of the shallow water marine environment. From this analysis, it emerges that EM communication may be, in the shallow water environment, a viable and good alternative to acoustic- and optical-based techniques. From this point on, this work is aimed to prove this possibility. The next step undertaken is the theoretical analysis of EM propagation in the shallow water environment, which is modelled as a stratified lossy dielectric. The outcome of theoretical calculations is that, within a certain distance, and for a given transmitter power, low frequency EM waves are a communication channel exploitable by underwater wireless sensor networks. This is particularly true when the required data rate is low, as it is in the case of monitoring variables such as temperatures or concentrations of dissolved substances in the sea. Following this, the electric dipole and the loop antenna are studied and compared when immersed in a lossy medium such as seawater. In particular, the comparison is drawn in terms of antenna size, with absorbed power and radiated field level held equal. This, together with other practical considerations, allows the choice of the electric dipole – with some variations with respect to free space applications – as the preferred transmitting and receiving antenna. Theoretical results are verified and completed by simulations, and final prototype design guidelines are presented, together with best deployment practice suggestions. Finally, measurements are conducted in order to verify the previous calculations and considerations. In addition to them, a sensor network prototype that uses EM underwater communication is presented and tested. The field tests verify, in a real situation and at several frequencies, the maximum distance coverable with a 100 mW power source. Moreover, the same test is also conducted in fresh water, and results are compared. The instruments used for the measurements are thoroughly described, as it is the wireless sensor prototype presented. The main feature of this design is its simplicity, demonstrating that shallow water EM communication is easily achievable and that it meets the standards required by a local area marine sensor network. It can be concluded that this work offers a thorough theoretical analysis of EM propagation in shallow water environment: in parallel with this, a synthesis of practical issues that are encountered in the design of EM communication devices for underwater sensor networks is also presented. In particular, EM underwater propagation, antennas, transmitters and receiver circuits and deployment issues are thoroughly covered. Aspects such as the application of advanced signal modulations and communication protocols, however, are intentionally left open to further investigation. In fact, the range of research topics opened by this work is very wide, and they could not be all covered within this work: they span from energy harvesting to communication protocols, from antenna design to power management. All these areas are well covered by literature for terrestrial sensor networks, but they are not covered for underwater sensor networks that use EM communication: these latter are, in fact, a novelty by themselves. The problems related to this particular application have been, therefore, thoroughly exposed and opened to future research.

abstract: Among the various end-use sectors, the commercial sector is expected to have the second-largest increase in total primary energy consump¬tion from 2009 to 2035 (5.8 quadrillion Btu) with a growth rate of 1.1% per year, it is the fastest growing end-use sectors. In order to make major gains in reducing U.S. building energy use commercial sector buildings must be improved. Energy benchmarking of buildings gives the facility manager or the building owner a quick evaluation of energy use and the potential for energy savings. It is the process of comparing the energy performance of a building to standards and codes, to a set target performance or to a range of energy performance values of similar buildings in order to help assess opportunities for improvement. Commissioning of buildings is the process of ensuring that systems are designed, installed, functionally tested and capable of being operated and maintained according to the owner's operational needs. It is the first stage in the building upgrade process after it has been assessed using benchmarking tools. The staged approach accounts for the interactions among all the energy flows in a building and produces a systematic method for planning upgrades that increase energy savings. This research compares and analyzes selected benchmarking and retrocommissioning tools to validate their accuracy such that they could be used in the initial audit process of a building. The benchmarking study analyzes the Energy Use Intensities (EUIs) and Ratings assigned by Portfolio Manager and Oak Ridge National Laboratory (ORNL) Spreadsheets. The 90.1 Prototype models and Commercial Reference Building model for Large Office building type were used for this comparative analysis. A case-study building from the DOE - funded Energize Phoenix program was also benchmarked for its EUI and rating. The retrocommissioning study was conducted by modeling these prototype models and the case-study building in the Facility Energy Decision System (FEDS) tool to simulate their energy consumption and analyze the retrofits suggested by the tool. The results of the benchmarking study proved that a benchmarking tool could be used as a first step in the audit process, encouraging the building owner to conduct an energy audit and realize the energy savings potential. The retrocommissioning study established the validity of FEDS as an accurate tool to simulate a building for its energy performance using basic inputs and to accurately predict the energy savings achieved by the retrofits recommended on the basis of maximum LCC savings. / Dissertation/Thesis / M.S.

Träbyggande har stark historisk förankring i Sverige. För drygt ett sekel sedan sattes ett förbud in mot att bygga hus i fler än två våningar i trä på grund av den ansedda brandrisken materialet medförde. Vid Sveriges inträdande i EU år 1994 togs det gamla beslutet bort och utvecklingen inom träbyggandet för flerbostadshus har därefter fått en rejäl uppgång. Utvecklingen har medfört ett modernare sätt att bygga, från att tidigare ha byggt allt på byggarbetsplatsen till montage av prefabricerade väggmoduler. Med detta tillvägagångssätt har byggandet både kunnat säkra en högre kvalitet samt effektiviserats.  Ett företag som arbetar med prefabricerade väggblock är Isotimber. Deras väggblock är unik på det sätt att de endast innehåller trä, för att uppnå ett högre isolervärde har råvaran trä kombinerats med urfrästa luftspalter. Isotimber har haft en önskan att utveckla sin produkt eftersom de fastskruvade kassetterna som bildar ett enhetligt väggblock separerar vid lyft. Lyftpunkterna har placerats genom borrade hål i väggblocken med genomförda lyftstroppar, ett tillvägagångssätt som Isotimber önskat förändra. Tvärkrafterna som uppstått vid lyften har verkat diagonalt mot väggblocken och antal lyftpunkter har varierat.  Studien har riktat sig mot att utveckla det befintliga väggblocket samt studera om lyft har gått att utföra på ett annat sätt än i dagsläget. Lyftpunkternas placering har även granskats.  Resultatet av produktutvecklingen har lett till att en limträbalk har placerats i överkant av blocken. Det har medfört att lyftpunkter har förflyttats till limträbalken där håltagning för stroppbanden kommer att utföras. Antal lyftpunkter har blivit beroende av väggblockens spännvidd och de tvärkrafter som uppstår vid lyft skall inverka vertikalt mot väggblocken. Resultatet av den nya väggblocksprototypen har krävt dimensionering av limträbalk vid lyftpunkter samt infästningarna mellan väggblock och limträbalk.  Väggblockets förändringar har bidragit till ett smidigare montagesystem. Den monterade limträbalken kan även anses ge en mindre nedböjning i väggblocket. Lyftpunkterna har blivit fler med bestämda avståndsintervall för att motverka separationer mellan de ihopskruvade kassetterna i väggblocken. / Building with   wood has a strong historical anchorage in Sweden. Just over a century ago, a   ban was imposed on building houses on more than two floors of wood due to the   perceived fire risk caused by the material. At Sweden's accession to the EU   in 1994, the old decision was removed and the trend in the construction of   wooden houses for multi-family houses has subsequently increased   dramatically. The development has resulted in a more modern way of building,   from building everything on the construction site to the assembly of   prefabricated wall modules. With this approach, construction has been able to   ensure a higher quality and efficiency.  A company that   works with prefabricated wall blocks is Isotimber. Their wall blocks are   unique in that they contain only wood, in order to achieve a higher   insulation value, the raw material wood has been combined with milled gaps of   air. Isotimber has had the desire to develop its product because the screwed   cassettes that forms a uniform wall block, separates during the lifts. The   lifting points have been placed through drilled holes in the wall blocks with   inserted lifting straps, an approach that Isotimber wishes to change. The   transverse forces that have occurred during the lift have acted diagonally   against the wall blocks and the number of lifting points has varied.  The study has   been aimed at developing the existing wall block and to study whether lifting   could be done in a different way than today. The position of the lifting   points has also been examined.  The result of   product development has led to a laminated wooden beam being placed above the   blocks. This has meant that lifting points have been moved to the laminated   wooden beam where perforation for the straps will be executed. The number of   lifting points has become dependent on the width of the wall blocks, and the   transverse forces that arise during lifting must be vertical to the wall   blocks. The result of the new wall-block prototype has led to dimensioning of   the laminated wooden beam at the lifting points, as well as the connections   between the wall block and the laminated wooden beam.  The wall block   changes have contributed to a smoother mounting system. The laminated wooden   beam can also be considered to give a smaller deflection in the wall block.   The lifting points have become more at fixed range intervals to counter the   separations between the screwed cassettes in the wall blocks. / <p>Betyg 170707, H14.</p>
