Abstract:

Online communities have become an increasingly popular channel for social interaction, enabling knowledge and opinion sharing across a board range of topics and contexts. Their viability and sustainability depends largely on contributions from community members in terms of time, resources, and knowledge. However, how individuals' knowledge contribution behavior changes over time and what network structural characteristics influence individuals' contribution behavior is not well understood. This study investigates "co-evolution" of social networks (i.e. advice network) and knowledge contribution behavior thorough a lens of social selection and social influence mechanism. This study are particularly interested in examining the dynamics of the advice network ties and the knowledge contribution behavior in the context of virtual financial communities in which people voluntarily participate to exchanges investing-related information. Unlike popular friendship-based online social networks, virtual financial communities in this study enables members to construct their own advice network by adding, maintaining, or terminating advice ties. Changes in network ties are referred to as social selection, while changes in individuals' behavior in response to the current network position are referred to as social influence. Dynamic network modeling is applied to investigate effects of social selection and influence separately and then examine the interplay between social selection and behavioral influence. Examination of such effects both separately and simultaneously requires a longitudinal data that capture dynamic changes in both the advice ties and the behavior under study.

Abstract:

The persistent demand for increased accountability and value for money in the public sector from both the public and governments raises the issue of quality of service in advice-giving by governmental agencies. The goal of this study is to develop a model to validate frameworks able to contribute to improved advice-giving through the application of knowledge management principles. Zack's (2001) Four Knowledge Problem Model, Brogowicz, Delene, and Lyth's (1990) Synthesised Service Quality Model, and Markus's (2001) Theory of Knowledge Reuse are used to examine knowledge strategies in advice-giving through the application of a case study methodology. Two Queensland public-sector call centres are investigated. This study confirms that although the studied call centres operate under differing business drivers, agents have developed strategies generally consistent with those suggested by Zack (2001) to deal with uncertain, complex, and ambiguous problem types. No equivocal problems were encountered in the study. The solution of the former problem pair of uncertainty and complexity relies on knowledge that is codified and stored in databases, while the latter equivocality and ambiguity, seeks out experts who apply both technical and functional knowledge to the problem resolution. Roles performed by call-centre agents predominantly align with those described by Markus (2001), with the opportunity to enhance performance through contribution by shared-work producers to knowledge repositories. The problem-solving strategies employed by agents and the technical capabilities of the call centres combine to deliver a level of service quality which, although meeting client expectations, has been able to be improved through the application of knowledge strategies targeting efficient problem resolution through knowledge reuse.

Abstract:

Relevant literature has been reviewed regarding the performance, implementation and evaluation of computer based medical decision support systems. The diagnostic performance of five simple case driven acute chest pain advice systems, have been compared using a standardized set of clinical records. A Bayesian inference model demonstrated superiority over two derived by logistic regression. Small data set flow charts performed well but both relied upon the use of expert opinion. A Bayesian acute abdominal pain diagnostic advice system has been evaluated in a clinical trial. Standardized data collection improved the diagnostic performance of doctors. In practice, the computer system offered little additional user benefit. From further tests in primary care, it was concluded that, whereas general practitioners might enhance their performance by using data collection sheets, paramedics might benefit through direct use of the computer. DERMIS is a new dermatology primary care diagnostic advice system. Components include a database derived from 5203 prospectively collected clinical records, a user interface, and an enhanced Bayesian inference model incorporating combined frequency estimates, expert beliefs and rationalized end-point groups. On laboratory testing, the diagnostic accuracy of DERMIS was 83%. The correct diagnosis appeared in the top three, of a possible 42 disease list on 97% of occasions. In a semi-field trial of DERMIS involving 49 general practitioners, doctors did not always collect the same information as a dermatologist but were able to significantly increase their chance of making a correct diagnosis through use of the computer system. It has been concluded that although implementation of DERMIS might well increase general practitioner diagnostic accuracy and lead to improvements in the management of skin disease in primary care, rates of referral for specialist opinion might not be affected unless standard management plans are adopted.

Abstract:

One of the most important conditions for effective performance and successful business operation is effective use of IT by organization members. Because of this demand in organizations, adaptation to IT-induced changes is one of the important challenges that organizations face with it. Technical-advice network has been used in order to better understand the effects of interpersonal communications on employee’s adaptation to IT-induced changes. In the other words the main focus of this research is to understand the effects of technical-advice network on individual IT-adaptation.

The research is carried out by the survey method in a unit of an organization with 51 employees. Two structural characteristics of the network have been examined as antecedents to adaptability. The results of study show that the strength of ties and density of network have positive effects on individual adaptation to IT-induced change. The research provided interesting results about the effects of technical-advice networks on individual adaptation to IT-induced changes.

Cass, Kimberly Ann. "Assessing the usefulness of domain and methodological tutorials for novice users employing an expert system as an advice-giving tool." Diss., The University of Arizona, 1988. http://hdl.handle.net/10150/184607.

Full text

Abstract:

The purpose of this dissertation is to examine the impact of domain and methodological tutorials on the attitude and performance of end-users who are neither well-versed in the domain area nor well-versed with an expert system which is designed to assist them in solving software selection tasks. With respect to these tasks and the mechanism for accomplishing them, the end-users can be categorized as "non-technical users." The design of this experiment was a 2 x 2 full factorial laboratory experiment employing eighty novice users as subjects. Each of the experimental subjects was randomly assigned to one of the four treatment groups corresponding to receipt or lack of receipt of tutorials concerning the problem domain and methodology employed by an expert system. The results of this research indicate that there is a significant interaction between receiving the application and expert system tutorial videos; better performance in terms of correct categorization of problems was observed in subjects who saw either both or neither video whereas worse performance was observed in subjects who saw only one video. In general, the video treatments were unrelated to a variety of attitude measures applied to the subjects. However, it was found that prior attitudes towards the use of computers were significantly related to the majority of the (posttest) attitude measures. Further, the general pattern was for attitudes towards computers to improve as a result of undergoing the experimental process with the viewing of the expert system video to be significant in the level of improvement.

Abstract:

Les Systèmes d’Aide au Vote (SAV) comparent, sur des enjeux variés, les positions des utilisateurs avec celles des partis ou des candidats qui sont établies à partir d’une analyse de contenu de leur programme électoral. Les SAV sont un outil d’analyse novateur à usage des politistes puisqu’ils leur permettent de récolter des données empiriques à grande échelle tout au long d’une campagne électorale. L'objectif principal de cette thèse est d'utiliser les données collectées par les SAV afin d’analyser la diffusion d’un site Web à caractère informatif et politique, i.e. les SAV, auprès des internautes dans des systèmes médiatiques différents. Cette thèse teste l'hypothèse selon laquelle l'utilisation des SAV par différents groupes d'électeurs (électeurs partisans, hésitants et indécis) varie selon les systèmes médiatiques. Les analyses des données collectées par des SAV dans sept démocraties électorales représentant trois différents types de systèmes médiatiques (Democratic Corporatist, Liberal et Pluralist Polarized) montrent que les systèmes médiatiques structurent les comportements et influent sur le degré d’exposition à des informations politiques en ligne. Le second apport de cette thèse est l’utilisation des données collectées par un SAV pour l'analyse électorale, notamment pour l’étude du vote sur enjeux et des dynamiques de campagne. Plusieurs analyses sont réalisées dans cette thèse à partir des données recueillies par le SAV français de La Boussole présidentielle. Cette thèse montre que, bien qu’étant non-probabilistes, les échantillons SAV sont très informatifs à condition d’être intégrés dans un cadre de recherche approprié et d’ajuster les biais statistiques
Online Voting Advice Applications (VAAs) are websites or online applications that show voters which party or candidate is closest to their own political ideas based on how they mark their positions on an ample range of policy issues. In addition to providing voters with reliable information in a structured manner, VAAs are an innovative data-collection tool on issue positions and on a wide set of other indicators. The main scope of this dissertation is to use VAA-collected data to learn about online information exposure during campaigns across media systems. Building on the realistic view of the Web’s political potential and its impact on the public, this dissertation test the hypothesis that VAA use by different voter groups (partisan, doubting and undecided voters) varies across media systems. The analyses of VAA-collected data in seven electoral democracies across three different types of media systems (Democratic Corporatist, Liberal, and Polarized Pluralist) show that media systems are key mediators to explain online information exposure. The second scope of this dissertation is to use VAA-collected data for the sake of electoral analysis, in particular to study issue-voting and campaign dynamics analyses. Several analyses are carried out using data collected by the French VAA of La Boussole présidentielle. This dissertation shows that, despite being non-probabilistic, VAA samples can serve as a very informative tool for the study of political and communication processes during electoral campaigns if integrated within an appropriate research framework and with the use of proper statistical adjustment

Adeogun, Oluseun. "Informatics for devices within telehealth systems for monitoring chronic diseases." Thesis, Cranfield University, 2011. http://dspace.lib.cranfield.ac.uk/handle/1826/6493.

Full text

Abstract:

Preliminary investigation at the beginning of this research showed that informatics on point-of-care (POC) devices was limited to basic data generation and processing. This thesis is based on publications of several studies during the course of the research. The aim of the research is to model and analyse information generation and exchange in telehealth systems and to identify and analyse the capabilities of these systems in managing chronic diseases which utilise point-of-care devices. The objectives to meet the aim are as follows: (i) to review the state-of-the-art in informatics and decision support on point-of-care devices. (ii) to assess the current level of servitization of POC devices used within the home environment. (iii) to identify current models of information generation and exchange for POC devices using a telehealth perspective. (iv) to identify the capabilities of telehealth systems. (v) to evaluate key components of telehealth systems (i.e. POC devices and intermediate devices). (vi) to analyse the capabilities of telehealth systems as enablers to a healthcare policy. The literature review showed that data transfer from devices is an important part of generating information. The implication of this is that future designs of devices should have efficient ways of transferring data to minimise the errors that may be introduced through manual data entry/transfer. The full impact of a servitized model for point-of-care devices is possible within a telehealth system, since capabilities of interpreting data for the patient will be offered as a service (c.f. NHS Direct). This research helped to deduce components of telehealth systems which are important in supporting informatics and decision making for actors of the system. These included actors and devices. Telehealth systems also help facilitate the exchange of data to help decision making to be faster for all actors concerned. This research has shown that a large number of capability categories existed for the patients and health professionals. There were no capabilities related to the caregiver that had a direct impact on the patient and health professional. This was not surprising since the numbers of caregivers in current telehealth systems was low. Two types of intermediate devices were identified in telehealth systems: generic and proprietary. Patients and caregivers used both types, while health professionals only used generic devices. However, there was a higher incidence of proprietary devices used by patients. Proprietary devices possess features to support patients better thus promoting their independence in managing their chronic condition. This research developed a six-step methodology for working from government objectives to appropriate telehealth capability categories. This helped to determine objectives for which a telehealth system is suitable.

Abstract:

La intenció d'aquest projecte de recerca és anar més enllà de l' aconseguit pels sistemes existents de selecció i comparació de processos de Prototipat Ràpid, mitjançant la introducció d'una nova metodologia que tingui com a únic fi la 'Fabricació Final' de components. El sistema desenvolupat incorpora algunes de les eines més recents del camp de Intel·ligència Artificial, de manera que sigui possible aconseguir una metodologia concurrent que inclogui:

· Sistemes experts, que s'executen durant el procés de presa de decisions amb alternatives múltiples. Els sistemes experts utilitzen típicament estructures del tipus: IF-THEN-ELSE o CASE, de manera que les opcions puguin ser 'cribrades' especialment durant les primeres etapes de la selecció.
· Lògica difusa per a la presa de decisions. Normalment en l'àmbit de la fabricació, alguns termes lingüístics o paràmetres de tipus qualitatiu són utilitzats per definir estats o propietats. Per exemple és comú trobar termes qualitatius com ara: 'bones propietats mecàniques "o" alta taxa d'absorbència', en lloc de xifres i números puntuals. Per tant és necessari comptar amb un mètode per traduir i gestionar aquesta informació. La lògica difusa ha estat adoptada com a mitjà per traduir termes d'ordre qualitatiu a informació quantitativa de manera que a partir d'aquestes dades es pugui construir un sistema de classificació i rànquing de processos.
· Presa de decisions Multi-criteri, agrupació (sumatòria) i classificació. Durant la investigació es van provar diferents mètodes per a la classificació d'alternatives i selecció final a partir de vectors d'ordre quantitatiu amb pesos ponderats. Per a aquesta finalitat es va adoptar la metodologia proposada per Lan et al. (2005) el qual es descriu en el capítol 5 d'aquest treball.
· Xarxes Neuronals Artificials. Aquestes han estat aplicades per a la modelització i simulació d'alguns processos de Fabricació Ràpida prèviament seleccionats. Per exemple, el procés de Sinteritzat Selectiu Làser es va aconseguir modelar utilitzant Xarxes Neuronals amb un algorisme de "backpropagation", prenent com a informació base, les dades proporcionades pel software propietari de l'equip. Aquesta xarxa neuronal simula una màquina de sinteritzat làser model DTM Vanguard, disponible a la FundacioCIM-UPC a Barcelona. D'altra banda el procés de Fusió selectiva per làser ha estat modelat també mitjançant Xarxes Neuronals a partir de l'equip Concep Laser M2, disponible al laboratori d'Enginyeria mecànica de la Universitat Catòlica de Lovaina, Bèlgica. Els models extrets d'aquestes simulacions mostren una estimació del temps total de fabricació menor al 10% la qual cosa representa una millora substancial respecte a mètodes d'estimació paramètrics.
· Finalment s'ha utilitzat la tècnica de bases de dades relacionals per a la gestió i emmagatzematge d'informació sobre materials. Aquestes bases de dades han estat creades en Ms Access, que proporciona la facilitat d'accés, filtrat, graficació i presentació de la informació requerida. Aquesta informació pot ser extreta automàticament mitjançant trucades ODBC, executades des de l'entorn Matlab.

Per a il·lustrar el funcionament de les eines descrites en una forma integrada, s'ha optat per desenvolupar una aplicació pilot en Matlab, utilitzant alguns "Tool boxes" especialitzats com: Lògica difusa, Xarxes neuronals, Estadística, Utilitats de graficació, Creació d'interfície d'usuari (GUI), Bases de dades. El resultat d'aquesta integració és una aplicació pilot anomenada RMADS (Rapid Manufacturing Advice System), el qual compta amb una interfície gràfica d'usuari que es divideix en tres mòduls:

· Requeriments generals de disseny. Aquest mòdul analitza els paràmetres usualment definits en les especificacions inicials de Producte, per exemple: tipus de material, toleràncies, acabat superficial, complexitat geomètrica, etc.
· Mòdul de costos. Aquest mòdul utilitza paràmetres d'entrada prèviament introduïts com: volum de peça, mida de lot i dimensions totals, per a realitzar càlculs mitjançant mètodes paramètrics i models basats en xarxes neuronals. El resultat és una estimació del cost per peça i també el cost estès per volums grans.
· Selecció de materials. Aquest mòdul mostra la natura iterativa del procés de selecció de materials, a través de criteris de "filtratge" o selecció, de manera que a cada iteració el nombre d'opcions sigui limitat a un nombre raonable d'alternatives.
The intention of this research is to go beyond currently available systems for the assessment and selection of Rapid Prototyping processes, hence introducing a new methodology devoted to 'Manufacturing' applications. Specifically the system would include a number of state of the art artificial Intelligence techniques to comprise a fully concurrent methodology, namely:
· Expert systems are included to aid in the decision making process with multiple alternatives. Expert systems typically use If-Then-Else or CASE structures so that the available options can be screened specially during the first selection stages.
· Fuzzy logic for decision making. Usually in manufacturing, linguistic terms or qualitative parameters are used to define states of properties. For instance it is common to find terms such as 'Good mechanical properties' or 'High absortivity rates' therefore it is necessary to have a method to translate and manage such information. Fuzzy logic has been adopted as a means to translate qualitative terms to quantitative information.
· Multi-criteria decision making, aggregation and ranking. Different methods for selecting and ranking alternatives were tested which allows the integration of quantitative vectors with weighting factors that reflect the user preferences. For this purpose the method proposed by Lan et al. (2005) has been adopted as discussed in Chapter 5.
· Artificial Neural Networks (ANNs) are being applied for the modelling and simulation of a number of Rapid Manufacturing Methods. Selective Laser Sintering has been modelled using a back propagation algorithm ANN taking as a basis the information provided by the machine software. The ANN simulates a DTM Vanguard SLS machine available at Fundacio CIM-UPC, Barcelona, while the Selective Laser Melting has been modelled with the parameters and settings used by the Concept Laser M2 machine available at the Mechanical Engineering Lab of the Catholic University of Leuven, Belgium. The extracted models exhibit a build-time prediction error rate lower than 10%, which is a significant improvement compared to conventional parametric methods.
· Finally, relational databases have been applied for storing and handling materials information. These databases have been stored as Ms Access data which provides the ease to access, filter, screen and plot the required information. This data can be automatically called and extracted by means of an ODBC call deployed within the Matlab environment.
In order to illustrate the functionality of the previous tools put together, a pilot application was designed in Matlab, making use of a number of specialized toolboxes namely: Fuzzy logic, Neural Network, Statistics, Plotting utilities, GUI builder, Database.
The result is a prototype system with a graphic user interface divided in three modules:
· General design requirements: which deals with those parameters usually defined in the product PDS, for instance: material type, tolerances, surface roughness, geometrical complexity, etc.
· Costing module: which makes use of parametric cost estimation and ANN-based models to perform the calculation of cost per part, and for low volumes
· Materials selection: Shows the iterative nature of materials selection through screening steps so that the range of suitable options is limited.

Full text

Abstract:

The Birmingham Maglev developed over fifteen years ago has successfully demonstrated the inherent advantages of low speed maglev over comparable wheeled systems. It remains the only commercially operational Maglev in the world today. To develop the next generation of Maglev vehicles which will overcome some of the limitations of the Birmingham system, such as chassis length and cost, the following issues are addressed in this thesis. 1) The possibility of interaction between the chassis resonant frequencies and the suspension control system causing poor ride quality and at worst instability, are formally analysed. In the Birmingham vehicle a stiff chassis (fundamental bending mode 40Hz) is used avoiding significant interaction with the suspension controller. Using advanced control strategies the low frequency chassis resonances can be controlled allowing a vehicle structure to be used with a fundamental bending mode of about 12Hz. 2) A modem control strategy is developed which delivers an improved ride quality compared with the present classical control system despite having to operate with a 'soft' chassis. Kalman filters are digitally implemented and conclusions drawn about their performance. The classical control strategy is also successfully demonstrated on a 3 m long 'flexible beam' rig. 3) An associated Maglev suspension problem for the response to ramp inputs such as the transition onto gradients which causes either a large steady state tracking error or a worsening ride quality is addressed by modern control theory using integral feedback techniques and classical theory using third order filters. These controllers are globally optimised by a multi-objective parameter optimisation system which formally considers the conflicts inherent in a suspension system between response to stochastic inputs and deterministic inputs.

There has been significant excitement surrounding the potential of desktop 3D printing. Some predict that household ownership for some users is only a few years away, while others go as far as to assert desktop printers will follow a comparable trajectory to personal computers. This thesis challenges the validity of these claims and presents a more realistic future state for desktop 3D printing based on the barriers that the industry faces today. This thesis also provides valuable insight into the technological and social improvement areas on which lead users, makers paces, and manufacturers alike must focus in order to take the steps necessary to transform desktop 3D printing into a viable, valuable, and usable technology for the masses. This thesis includes four elements: 1) a thorough literature review, 2) a review of industrial and desktop 3D printers, 3) field interviews with existing and potential users, and 4) a makerspace review. Together, these study areas provide a system-level view of the current state of the desktop 3D printing industry, reveal a unique set of barriers preventing the technology from reaching the mainstream stage, and offer valuable evaluations regarding the efficacy of active enabling mechanisms. It is shown that, although the current enablers will eventually help push desktop 3D printing utilization to the mainstream stage, a significant amount of time and energy must be dedicated to this effort. Over the course of the next ten years, a sharp increase in the use of desktop 3D printing will be observed, but this use will be limited almost exclusively to users accessing 3D printers via qualified technologists in makerspaces and other educational settings. It will be crucial for lead users and manufacturers to focus on fostering the current enablers and implementing the potential enablers over the course of the next ten years in order for users to understand and be able to capture the value of desktop 3D printing.

Abstract:

Conventional cutting fluids are an absolute necessity in today’s manufacturing domain, butthey are a polluting and non-sustainable part of modern manufacturing processes. These conventional cutting fluids can be replaced by cryogenic cooling, which is an innovative and sustainable method which has been successfully implemented to produce aerospace products and have shown great success and great quality of finished products. But the implementation is the main obstruction as the volume of production in aerospace and automotive components is quite vast and implementation of cryogenic may pose an obstruction in maintaining the production flow. This leaves us with a large unexplored area for research specially in the implementation of the system in the existing system, which canhelp us get a seamless transition from conventional to cryogenic cooling. Some of the notable points that there is a need to investigate before one can go ahead with the implementationare factory layout, chip removal, raining of personal, safety, monitoring system, cost, time, implementation and integration, maintenance, source placement, mass scale supply and quality. In the first part of this work, a deep literature study has been done to know all the aspects of cryogenics and its implementation and factors that must be considered. In the second a discussion about the target industries has been made where use of cryogenic cooling has been considered. Also, a small discussion about the existing companies that provide this system has also been discussed. The room for improvisation is very large, and a lot of physical testing needs to be conducted before it can be successfully implemented.
Konventionella skärvätskor är en absolut nödvändighet inom dagens tillverkningsdomän, men de är en förorenande och icke-hållbar del av moderna tillverkningsprocesser. Dessa konventionella skärvätskor kan ersättas med kryogen kylning, som är en innovativ och hållbar metod som framgångsrikt har implementerats för att producera flyg- och rymdprodukter och har gett stor framgång och hög kvalitet på färdiga produkter. Men implementeringen är den största utmaningen eftersom produktionsvolymen för flyg- och bilkomponenter är ganska stor och implementering av kryogen kan utgöra ett hinder för att bibehålla produktionsflödet. Detta ger oss ett stort outforskat område för forskning speciellt vid implementeringen av systemet i det befintliga systemet, vilket kan hjälpa oss att få en sömlös övergång från konventionell till kryogen kylning. Några av de viktige punkterna som man måste undersöka innan man går vidare med implementeringen är fabrikslayout, spånborttagning, utbildning av personal, säkerhet, övervakningssystem, kostnad, tid, implementering och integration, underhåll, källans placering, storskalig produktion och kvalitet. I den första delen av detta arbete har en omfattande litteraturstudie gjorts för att lära alla aspekter av kryogen kylning och dess genomförande och faktorer som måste beaktas. I den andra har en diskussion om målgruppen inom industrin genomförts där användning av kryogen kylning är relevant. Dessutom har en liten diskussion förts om de befintliga företagen som tillhandahåller dessa system. Möjligheten till improvisation är mycket stor och mycket testning måste genomföras innan tekniken kan implementeras framgångsrikt.

Abstract:

In this study, value of quality information and the eects of centralization are investigated for a reverse supply chain consisting of a remanufacturer and a collector. Used products are collected and inspected to classify them into quality groups, then they are remanufactured to meet the demand of remanufactured products. The supply of collected products and demand of remanufactured products are both price-sensitive. The uncertain quality of the collected products is revealed by an inspection process. Two quality classes are considered, and the cost of remanufacturing depends on the quality class. The main decisions are on acquisition fee for the returns, the selling price for remanufactured products, and the transfer prices of inspected products between the collector and the remanufacturer. For this environment, centralized and decentralized settings are considered and dierent models that dier in availability of quality information when the pricing decisions are made are built. We explore the value of advance quality information and eects of centralization on the optimal prices and profits via a computational study.

Abstract:

Thesis (S.M.)--Massachusetts Institute of Technology, System Design and Management Program, 2007.
Includes bibliographical references (leaves 161-167).
External advice can be a valuable resource for founders of high technology startup companies. As with any resource, the pursuit and efficient use of the external advice resource is one of the greatest challenges for founders. This thesis examines how the founders of eleven US venture-backed high-tech companies leveraged external advice to their advantage. By aggregating data extracted from case-based interviews, the characteristics of advice are fully understood. In particular, insights are made into the types of advice these business focused founders received, the types of advisors they selected and considered influential to the development of their company and the way they were connected to these influential advisors. Organizing the data by companies' business characteristics enabled further insights to be drawn. Notably, there was a significant difference in a variety of the advice sought by first time founders compared with that of more experienced founding teams. First time founders received broader and more tactical advice than did experienced founders. Furthermore, first time founder's advisors were much more likely to act as coaches, instilling confidence and expending effort to mentor these first-timers into successful CEOs. Silicon Valley advisors and others affiliated with Silicon Valley companies were much more likely to introduce the founders to their influential network, which illustrates the rich entrepreneurial nature of Silicon Valley. There was no statistically significant difference in advice characteristics based on the size of their founding team or on type of their industry. Since the eleven companies are private and thriving, the selected performance metric was the amount of venture capital raised per year of existence.
(cont.) This less than ideal performance data clearly shows a positive correlation between the size and experience of the founding team with company performance. However, no correlation between company performance and industry and geography could be determined. Since the advice characteristics that were correlated with performance were similar to those of large experienced teams, it is reasonable to conclude that none of the advice characteristics are predictors of success. It follows rather that advice characteristics are more a reflection of the companies' business characteristics than itself a predictor of venture success.

Abstract:

The purpose of this study is to provide a simple user interface with which everyone can

design his/her own game, and play it on Game Boy Advance console. This project helps

people develop games without having programming knowledge. Everything is done by means of a user interface and without any programming knowledge. It is magic, isn’t it?

Game Boy Advance is a game console developed by Nintendo. In order to market their

products, they must also develop games running on their products. Every time they develop a game for the Game Boy Advance console, they have to implement a low level C++ application over and over again. This makes things more complicated. However, if this software is used, everything becomes easier.

This project can be seen as an interpreter that interprets the designed game, which is

very high level, and converts it to a Game Boy Advance game. If this project is finished

successfully, game design for Game Boy Advance will experience a revolution in its history.

In brief, it is required to develop a visual, GUI‐based system that allows people to develop games for the Game Boy Advance console. This GUI system is required to

implement and use the API (Game Engine) developed by Lypson.

Abstract:

This study investigated the effects of advance organizers on the English reading comprehension of six bilingual learning disabled students. Little research has examined instructional strategies for teaching bilingual learning disabled students, a growing population in our schools. Based on research dealing with the use of advance organizers as an instructional strategy and on research in bilingual education, this study compared the effectiveness of using advance organizers on the English reading comprehension of six learning disabled students whose primary language was Spanish. An alternating treatment design was maintained. Following each treatment, the students read an expository text written in English and answered eight comprehension questions based on five levels of reading taxonomy. The number of correctly answered comprehension questions was recorded on graphs and statistically analyzed to compare the treatment conditions. In addition, the average proportion of correct responses for different levels of questions was computed and analyzed. Analyses of the data suggest that advance organizers were effective particularly when presented in the dominant language of the student. The five students who demonstrated equal or greater language proficiency in English scored higher when the English advance organizer was compared to the Spanish advance organizer. The student who demonstrated greater language proficiency in Spanish scored higher on the Spanish advance organizer. All students scored higher when the English advance organizer was used in comparison to no advance organizer. Three of the students scored higher on reading comprehension when the advance organizer was presented in Spanish as compared to no advance organizer. Students performed highest on questions at the appreciation and evaluation levels of the reading taxonomy. This study supports the body of research which suggests advance organizers are an effective instructional strategy and suggests their effectiveness with bilingual learning disabled students. This study also highlights the importance of considering students' dominant language, particularly their cognitive/academic/language proficiency, when determining the language for presentation of the advance organizer. Further research needs to systematically investigate the interrelationship between advance organizers and students' dominant language when attempting to facilitate English reading comprehension.

Full text

Abstract:

In times of demand shocks, when quantitative forecasting based on historical time series becomes obsolete, the only information about future demand is "advance demand information", i.e. interpreting early customer bookings as an indicator of not yet known demand. This paper deals with a forecasting method which selects the optimal forecasting model type and the level of integration of advance demand information, depending on the patterns of the particular time series. This constitutes the applicability of the procedure within an industrial application where a large number of time series is automatically forecasted in a flexible and data-driven way. The architecture of such a planning system is explained and using real-world data from a make-to-order industry it is shown that the system is flexible enough to cover different demand patterns and is well-suited to forecast demand shocks.

Abstract:

In this study we address a periodic review capacitated inventory system with supply uncertainty where advance demand information is available. A stochastic dynamic programming formulation is applied with the objective of minimizing the expected inventory related costs over a finite horizon. Three different supply processes are assumed. Under the all-or-nothing type supply process and partially available supply process, the structure of optimal policy is proved to be a base stock policy and numerical examples are given to demonstrate the effects of system parameters. Under Binomially distributed supply process it is shown that a simple base stock policy is not optimal.

Abstract:

Financial markets, particularly capital and stock markets, play an important role in mobilizing and canalising the idle savings of individuals and institutions to the investment options where they are really required for productive purposes. The prediction of stock prices and returns is carried out in order to enhance the quality of investment decisions in stock markets, but it is considered to be tricky and complicates tasks as these prices behave in a random fashion and vary with time. Owing to the potential of returns and inherent risk factors in stock market returns. Various stock market prediction models and decision support systems such as Capital asset pricing model, the arbitrage pricing theory of Ross, the inter-temporal capital asset pricing model of Merton ,Fama and French five-factor model, and zero beta model to provide investors with an optimal forecast of stock prices and returns. In this research thesis, a stock market prediction model consisting of two parts is presented and discussed. The first is the three factors of the Fama and French model (FF) at the micro level to forecast the return of the portfolios on the Saudi Arabian Stock Exchange (SASE) and the second is a Value Based Management (VBM) model of decision-making. The latter is based on the expectations of shareholders and portfolio investors about taking investment decisions, and on the behaviour of stock prices using an accurate modern nonlinear technique in forecasting, known as Artificial Neural Networks (ANN). This study examined monthly data relating to common stocks from the listed companies of the Saudi Arabian Stock Exchange from January 2007 to December 2011. The stock returns were predicted using the linear form of asset pricing models (capital asset pricing model as well as Fama and French three factor model). In addition, non-linear models were also estimated by using various artificial neural network techniques, and adaptive neural fuzzy inference systems. Six portfolios of stock predictors are combined using: average, weighted average, and genetic algorithm optimized weighted average. Moreover, value-based management models were applied to the investment decision-making process in combination with stock prediction model results for both the shareholders’ perspective and the share prices’ perspective. The results from this study indicate that the ANN technique can be used to predict stock portfolio returns; the investment decisions and the behaviour of stock prices, optimized by the genetic algorithm weighted average, provided better results in terms of error and prediction accuracy compared to the simple linear form of stock price prediction models. The Fama and French model of stock prediction is better suited to Saudi Arabian Stock Exchange investment activities in comparison to the conventional capital assets pricing model. Moreover, the multi-stage type1 model, which is a combination of Fama and French predicted stock returns and a value-based management model, gives more accurate results for the stock market decision-making process for investment or divestment decisions, as well as for observing variation in and the behaviour of stock prices on the Saudi stock market. Furthermore, the study also designed a graphic user interface in order to simplify the decision-making process based upon Fama and French and value-based management, which might help Saudi investors to make investment decisions quickly and with greater precision. Finally, the study also gives some practical implications for investors and regulators, along with proposing future research in this area.

Abstract:

In many situations, different consumers have different degrees of willingness to wait to get delivery of a product. So, consumers can be segregated based upon the demand lead time they are providing. In this paper, two types of consumers have been considered. The first category needs immediate delivery of the product, so there is no demand lead time; whereas for the other category, demand lead time is positive. A manufacturer, which produces the items using a base stock policy, can benefit from the advance demand information that the second category of consumers are providing. Early fulfillment for a particular order means fulfilling the order before the demand lead time. In this research, it is shown that a restrictive early fulfillment policy can help the firm to reduce the chances of order loss. A production control approach for restrictive early fulfillment is discussed and the factors that may affect the early fulfillment policy are examined.

Full text

Abstract:

Modern radiation belt models can be broadly split into either physics-driven diffusion based algorithms, or data science techniques that utilise the continuous data coverage from satellites at geostationary orbit and the Lagrange point L1 to apply statistical data analysis methods to predict electron fluxes at geostationary orbit. The first kind, while posessing generality due to their physical nature, lack accuracy compared to their data-driven counterparts. This is because the magnetosphere is a highly complex system that is not easy to model and its dynamics are not yet fully understood. Meanwhile, data-driven methods possess statistical accuracy, but cannot predict outside their operating parameters, and so on their own provide no information about what happens in the wider radiation belt region. This thesis is devoted to the development of a model that combines the two approaches into one unified system, attempting to combine the predictive range of physical modelling with the accuracy of the data-driven approach. This model uses geosynchronous orbit fluxes predicted using an advanced data science technique as an input to drive a physics-based radiation belt modelling code. The model has been developed and tested for a range of energy channels, magnetospheric conditions, and with various modifications. It was validated using data from NASA's recent Van Allen probes mission and with NOAA's GOES-13 geostationary satellite. The model results are in good agreement with observations, with the sources of inaccuracies explored in the manuscript. This work is a first attempt to create such a model, and potential improvements are outlined that should further increase accuracy. A further modification of the model is explored that is found to provide superior performance at geostationary orbit at the cost of degraded performance elsewhere. It is proposed to use this modification in tandem with the main model, where accurate information about geostationary orbit is required. The modification has been tested on long-duration time periods and was found to generate good predictions for high-energy electron fluxes. The role of electromagnetic ion cyclotron (EMIC) waves is explored using wave vector analysis and calculation of minimum resonant energies. The aim is to identify what effect EMIC waves have on electron dynamics at energies below 1 MeV. The conclusions are that EMIC waves, under certain conditions, do affect these electron populations in the magnetosphere, and their effect should be included in a representative radiation belt model. This is suggested as a further improvement to the simulation.

Full text

Abstract:

This thesis investigated marine isotope stage {MIS) 3-2 glacial sequences in the South Fork Hoh River Valley, Washington and the Lake Hawea Valley, New Zealand. Research objectives were to reconstruct the style and timing of ice advance in both areas and to assess the viability of luminescence dating of glacial sediments in various depositional facies and distances from the ice front. This thesis focused on the sedimentology and stratigraphy of surficial and older glacial sequences in the South Fork Hoh and Lake Hawea areas and used OSL and radiocarbon dating techniques to establish age control for the deposits. Specifically, this research identified, described, and dated the stratigraphy of glacial sequences in order to reconstruct ice dynamics. This work also presents updated geomorphic maps for both study areas as an additional way to show ice advance and retreat events recorded in deposited sediment and geomorphic surfaces. The glacial sequence expressed in the Lake Hawea moraine exposure shows four distinct depositional events that represent retreat from an ice position down -valley, re-advance to the Hawea moraine position, and subsequent retreat and deglaciation broadly spanning -32-18 ka. These results document the terminal glacial advance and subsequent retreat in the Lake Hawea Valley and contribute to the wider swath of research studying the last phase of glacial retreat and its connections to climate on the South Island of New Zealand. The Hawea chronology corresponds to other glacial records and paleoclimate reconstructions from the South Island that collectively suggest the commencement of deglaciation at -13 ka. Three late Pleistocene ice positions are preserved in the South Fork Hoh River Valley, here referred to as South Fork 1-3 (SF 1-3). One of these positions has not previously been recognized in this valley or in the mainstem Hoh River Valley. Optically stimulated luminescence (OSL) and radiocarbon (14C) ages are generally consistent throughout the valley. These finding s advocate for a detailed sedimentologic and stratigraphic approach to glacial depos its and questions whether a similar advance or still -stand occurred in other valleys in the region. If so, this may reveal information regarding climate influences on MIS 2 glaciers in the Olympic Mountains. This research also assesses the applicability of OSL dating to glacial deposits in both field areas. Quartz OSL dating was used in the South Fork Hoh study area; however, quartz produced unreliable results in the Hawea study area, so samples were therefore assessed using feldspar methods. The results advocate for a facies-based sampling approach in glacial settings, where better sorted sandy facies and more distal deposits produce better bleached and more reliable age results than other deposits.
