A Method to Quantify Road Safety Audit Data and ResultsJones, Joshua Reid 01 May 2013 (has links)
The research presented in this thesis is the result of field data collection conducted by the Utah Local Technical Assistance Program (Utah LTAP) in conjunction with the Utah Department of Transportation. The first step of the research was data collection from 18 road safety audits conducted throughout the state of Utah. These Road Safety Audits (RSA's) provided a wide variety of data that was used for the validation of the road safety audit quantification methodology. The purpose of this research is to provide quantification to the RSA process that will increase the benefits gained from implementing the RSA recommendations. Benefits derived from the implementation of RSA recommendations were found by assessing the change of risk from before and after safety improvements. The RSA quantification tool was developed to analyze projects in both urban and rural settings. The implementation of the RSA tool will help practitioners show the benefits that can be gained from the safety recommendations and help decision makers in allocating funds to the areas that pose the most risk. The tool will show the difference in risk that the improvements make and the cost effectiveness of different project alternatives.

Understanding Successful Japanese Language Programs: Utah Case StudyStout, Timothy G. 01 May 2013 (has links)
Recent world events have caused Americans to reassess national political, economic, and educational priorities, resulting in a shift towards Asia. The schools in response have begun to introduce less commonly taught languages, such as Japanese and Chinese. Many Utah public schools have tried to implement less commonly taught language programs. Some have succeeded, and other others have not. The purpose of this study was to understand how and why some schools were able to successfully integrate less commonly taught language programs, and why others were not.The results of this study suggest that the factors relating to students’ interests and the teacher/administrator relationship were the most important positive factors affecting the success of the Japanese programs with staying power. It was also found that the factors relating to funding issues and student enrollment were the most important negative factors affecting the failure of the long-term Japanese programs that were eliminated.

An Educational Transition: Post-Secondary Correctional Education - A Qualitative Case StudyBartholomew, Greg 01 May 2013 (has links)
This study examines the transition of a post-secondary correctional education (PSCE) system formerly facilitated by higher education to the current system administered by the State Department of Corrections (SDC). This study used qualitative case study methodology utilizing multiple perspectives from five different stake-holding groups or five socials units: state legislators, county law enforcement personnel, state higher education administrators, SDC personnel, and technical college personnel. A thick, rich description of the transition was obtained by relying on multiple perspectives recorded in interviews of stakeholders in PSCE.The stakeholders’ perception of this educational transition that changed PSCE in one state was shaped by personal perspectives on issues surrounding the education of the incarcerated. The rhetoric, political machinations, and reality of this transition define stakeholders’ perspectives of the driving forces that initiated the facilitation of PSCE from a Higher Education run system to one run by the SDC.

[en] A STUDY ABOUT THE PERFORMANCE AND THE CONVERGENCE OF GENETIC ALGORITHMS / [pt] UM ESTUDO SOBRE O DESEMPENHO E A CONVERGÊNCIA DE ALGORITMOS GENÉTICOSRODRIGO MORAES LIMA DE ARAUJO COSTA 07 August 2006 (has links)
[pt] Esta dissertação investiga a convergência e o desempenho
de Algoritmos Genéticos: os problemas, soluções e medidas
propostas. O trabalho consiste de cinco partes principais:
uma discussão sobre os fundamentos matemáticos que buscam
explicar o funcionamento de um Algoritmo genético; um
estudo dos principais problemas associados à convergência
e ao desempenho de Algoritmos genéticos; uma análise das
técnicas e algoritmos alternativos para a melhoria da
convergência; um estudo de medidas para estimar o grau de
dificuldade esperado para a convergência de Algoritmos
Genéticos; e estudo de casos.
Os fundamentos matemáticos de Algoritmos Genéticos têm por
base os conceitos de schema e blocos construtores,
desenvolvidos por Holland (apud Goldberb, 1989a). Embora
estes conceitos constituam a teoria fundamental sobre a
qual a convergência se baseia, há, no entanto, questões
importantes sobre o processo através do qual schemata
interagem durante a evolução de um Algoritmo genético
(Forrest et al, 1993b). Este trabalho apresenta uma
discussão sobre os principais questionamentos que têm sido
levantados sobre a validade destes fundamentos. São
discutidas as controvérsias geradas pela necessidade de
uma visão dinâmica dos Algoritmos Genéticos, onde a
amostra da população e os resultados obtidos pela
recombinação sejam considerados. Em especial, as objeções
apontadas pro Thornton (1995) quanto à coerência da
associação dos conceitos de schema e blocos construtores,
a contradição entre os Teoremas schema e Price vista por
Altemberg (1994), e as idéias de adequação do Teorema
Fundamental de Algoritmos Genéticos ao conceito de
variância dentro de uma população.
Os principais problemas de convergência e desempenho de um
Algoritmo Genético foram discutidos: a Decepção e a
Epistasia. É apresentada a idéia de que a Decepção, embora
esteja fortemente ligada à dificuldade de convergência de
Algoritmos Genéticos, não constitui fator suficiente para
que um problema seja considerado difícil para um Algoritmo
genético (GA-hard problems) (Grefenstette, 1993). São
também apresentados os coeficientes de Walsh (Goldberg,
1989b) e demonstrada a sua relação com as idéias de schema
e epistasia, e sua utilização em funções decepcionantes.
São analisadas diversas funções decepcionantes. São
analisadas diversas funções, associadas aos conceitos de
Decepção e Epistasia: as funções fully-deceptive e fully
easy com 6 bits, propostas por Deb e Goldberg (1994); as
funções deceptive but easy e non-deceptive but hard de
Grefenstette (op. Cit.); as funções F2 e F3 de Whitley
(1992), e ainda, as funções NK (apud Harvey, 1993) e Royal
Road (Forrest et al, op. Cit.)
Técnicas alternativas para melhorar a convergência incluem
basicamente algoritmos evolucionários com características
específicas a determinado tipo de problema. São analisados
alguns algoritmos alternativos, como o Messy de Goldberg
et alli (1989), o Estruturado de Dasgupta et al (s.d.), o
aumentado de Grefenstette (ibidem) e os algoritmos
propostos por Paredis (1996b). É ainda discutida e
exemplificada a importância da escolha adequada de
parâmetros e da representação de cromossomas, para que a
convergência seja mais facilmente alcançada.
O estudo de medidas de convergêcia de Algoritmos
Genéticos fornece uma classificação: medidas
probabilísticas e medidas baseadas em landscapes. São
apresentadas também as colocações de Koza (1994) e
Altemberg (op. Cit.) sobre a convergência de Algoritmos
Evolucionários. É dado destaque para medida da dificuldade
esperada para convergência baseada no Coeficiente de
Correlação entre a Aptidão e a Distância (FDC - Fitness
Distance Correlation), como proposto por Jones e Forrest
(1995b).
O estudo de casos consiste da análise do comportamento de
Algoritmos Genéticos pela medida FDC, quando aplicados a
um conjunto de funções matemáticas, incluindo as já citadas, e ainda as funções de teste propostas por De Jong (apud Goldberg, op. cit) e a função decepcionante de Liepins e Vose (apud Deb et al, 1994). Também é realizada uma extensão da medida de dificuldade FDC estudada, buscando adequá-la a uma visão mais dinâmica de Algoritmos Genéticos. Para executar estes testes, o ambiente GENEsYs 1.0, desenvolvido por Thomas Bäck (1992) (a partir de seu precursor Genesis de JOhn Grefenstette (apud Ribeiro et alli, 1994), foi adaptado e extendido. / [en] This wok investigates the convergence and the performance
of Genetic Algorithms: the problems, solutions and
proposed measures. It is divided into five topics: a
discussion on the mathematical foundations that explains
how Genetic Algorithms work: a study of the most important
problems associated to their convergence and performance;
an analysis of techniques and alternative Genetic
Algorithms to achieve better convergence; a study of
measures trying to estimate the level of difficulty for
the convergence of GA s; and case study.
The mathematical foundations are based in conceps of
schema and building blocks, developed by Holland (apud
Goldberg, 1989a). Although they constitute the fundamental
theory about Genetic Algorithms convergence, there has
been a lot of questions about the process in which
schemata interact during the evolution of GA s (Forrest et
al, 1993b). This work presents a discussion on the most
important questions that have been raised about the
validity of these foundations. Specifically the objections
pointed out by Thorton (1995) about the conference of the
association between schema and building blocks; the
contradiction between schema theorem and Price theorem,
mentioned by Altenberg (1994); and the new ideas raised by
the variance of fitness concept.
The most important problems related to the convergence and
performance of GA s are discussed, i.e. the Deception and
the Epistasis. Even though Deception can difficult the
convergence, the former does not constitute a sufficient
factor for the late (Grefenstette, 1993). The Walsh
coefficients (Goldberg, 1989b0 and their relation with
schema are presented, and also their utilization in
deceptive fuctions. Some functions are analised, based on
the concepts of Deception and Epistasis: the 6-bits fully-
deceptive function by Deb et all (1994): the 3-bits fully-
deceptive functions, by Deb et alli (1989); the functions
deceptive but easy and non-deceptive but hard of
Grefenstette (op. cit.) the F2 and F3 functions of Whitley
(1992) as well as the NK functions (apud Harvey, 1993) and
the Royal Road functions (Forrest et al, op. cit.).
The techniques included the alternative GA s, with special
carachteristics. The Messy GA of Goldberg (1989), the
Structured GA of Dasgupta (s.d.), the Augmenated GA of
Grefenstette (ibidem) and GA s fo Paredis (1996b). The
importance of a correct choice of parameters is also
discussed.
The study of measures classifies those Ga´s into two
types: probabilistics and based on landscapes. The
considerations of Koza (1994) and Altenberg (op. cit.) are
also discussed. It is given special enfasis to the FDC (
Fitness Distance Correlacion) measure, proposed by Jones
and Forrest (1995b).
The case study consists of the analysis of the behavior of
GA by the measure FDC, applied to a set of mathematical
functions. The environment used is GENEsYs 1.0, developed
by Thomas Bäck (1992) over the Genesis of Grefenstette.
The GENEsys 1.0 was adapted and expanded to fullfil the
requirements of this work.

Employee innovation of IoT applications: A framework to facilitate capability, opportunity, and intentSjölund, Markus January 2019 (has links)
Purpose: The purpose of this study was to augment the understanding for how an organisation can facilitate the creation of applications of the Internet of Things (IoT) through increased involvement of employees in the innovation process. Method: This was an explorative study utilising qualitative data that was collected from a single case. Data was collected from a process manufacturing facility owned by a market-leading company through a combination of methods: questionnaire, documentation, observation, and interviews. Findings: It was found that the employee innovation process occurs in eight stages: problem-identification and communication, and idea-generation, communication, assessment, prioritisation, assignment, and implementation. It was also found that to successfully innovate, employees require knowledge, time, and motivation. Further, seven enabling and six inhibiting factors of employee innovation were identified. The process, requirements, and factors were utilised to build a framework to facilitate employee innovation for applications of the IoT. Theoretical contributions: This study merged two rather young bodies of literature, IoT and employee innovation, in a novel way. Innovation related to the IoT is close to unexplored, and employee innovation has never been studied specifically related to the IoT. Further, the eight-stage process of employee innovation is also novel. Managerial implications: There now exists a framework that managers can utilise to facilitate employee innovation in general, and innovation for the IoT in particular. The findings of this study can act as guidance for managers seeking to involve their employees in the innovation process.

Developmental Approaches to Reading Comprehension in Children with Reading Difficulties.Kingham, Patricia Hope January 2003 (has links)
Previous studies have shown some students with good word recognition skills and high levels of reading fluency fail to comprehend what they read.This study examined the explicit teaching of the rule based Question Answer Response (QAR) strategies to overcome specific learning difficulties in reading comprehension. Case study methods were used on five Year 4 students in Western Australia who were at different developmental levels in reading comprehension.The study revealed that within the conceptual framework of the transactional model of reading, the Question Answer Response strategies were effective in improving literal, inferential, critical and creative comprehension at varying levels for each of the five students in the study. The strategies also proved to be an effective way to teach the resolution of anaphoric pronouns that are particularly problematic for students with poor comprehension.The study indicates that the teaching of reading comprehension skills to students with reading comprehension problems through explicit rule based instruction is an important component of classroom-based instruction in the literacy learning area.

An exploration of the experience of children and prospective parents as they transition into a permanent placement arrangement: an interpretive collective case studyShinkfield, Carol January 2007 (has links)
This research study examines the psychological and emotional experiences of children and parents as they embark on a permanent placement living arrangement. A permanent placement living arrangement is entered into when a child is no longer able to reside with their family of origin. Three family groups participated in the study and separate interviews were conducted with both the children and placement parents. Overall, three interviews were conducted, with the first interview taking place prior to the child’s transition into the family. A further two interviews were conducted with the participants after the transition had taken place. The findings of this study indicate that both the parents and children were profoundly affected by the experience of permanent placement. The common themes that emerged from the data were the hopes, anxieties and coping strategies of the participants which became the focal point of analysis. The parents experienced a mixture of fulfilment, tempered with anxieties of whether they would be able to provide adequate care for the child placed with them. Whereas, the children appeared to find it difficult to trust that this experience would be any different from their previous experiences. The study concludes that further attention is needed in the preparation for the transition into permanent placement. It further concludes that ‘after transition’ support is important to the stability of the placement.

The evolution of global intellectual property instruments into trade related intellectual property rights (TRIPS) and its ineffective enforcement in developing world: a case studyNasir, Saeed January 2008 (has links)
This thesis aims to critically evaluate global intellectual property instruments with detailed analysis of the Agreement on Trade-Related Intellectual Aspects of Property Rights (the TRIPS Agreement) provisions in order to investigate the enforcement issues, confronted by the Developing Countries due to fragile legal infrastructure. These intellectual property laws are evolutionary and designed to protect and honour human intellectual creations since BC 400 which recognized them distinct from divine inspirations. Italian Renaissance witnessed the systematic recognition of human skill, craft, innovation and invention. Venetian Government institutionalized it by awarding patents and copyrights to skilled workers and publishers. Its primary purpose was to protect the trade and secondary was to foster intellectual creativity through reward and recognition. These rewards and recognitions, known as Intellectual Property Rights (IPRs), developed with each new invention and creation. Industrial Revolution accelerated it and developed nations entered into international conventions to protect their nationals and their interests across the borders. In 1995, the Agreement on Trade-Related Aspects of Intellectual Property Rights (the TRIPS Agreement) accommodated all the previous (IPRs) instruments and its enforcement linked with global trade. It was a dilemma for developing nations who were desirous to participate in global trading system for their economic development but could not administer (IPRs) regimes on their land due to fragile and static infrastructure. All assistance from developed countries during the transitional period could not address the problems due to alien prescriptions, applied to counter problems in the developed World. Developing Nations need innovative, flexible and indigenous approach to administer the TRIPS Agreement. A case study of Pakistan judicial environment to address the TRIPS enforcement issue has been conducted. The methodological approach of this thesis is the interpretive paradigm of the qualitative research tradition. This interpretive paradigm or framework is applied through the two methodologies of hermeneutics and case study.

Bridging to new possibilities: a case study of the influence of a bridging education programmeWalker, Catherine January 2008 (has links)
In the rapidly changing ‘knowledge economy’ where ‘innovation’ and ‘responsiveness’ are vital, tertiary education can be at a point transformation. Since the late 1990s the New Zealand government began to shift part of its tertiary education policy with an increasing focus on what is commonly called ‘foundation’ education. The shift was aimed at ensuring all New Zealanders are equipped for the knowledge economy and raising the skills of individuals. A variety of research and education programmes were launched, and existing foundation or bridging programmes strengthened through policy, research and educational endeavours. Bridging education programmes (a subset of foundation education) are designed to prepare non-traditional and under-prepared students for ongoing study at a higher level. This current research sought to identify the influence of a university bridging programme (Level 4) on students who progressed into further study at undergraduate level. The bridging programme commenced in 2003 providing a pathway for students into undergraduate health degrees. The key question for this thesis was: how does bridging education influence students? To determine the influence of the bridging programme, this research was based on a case-study of seven students who completed four or eight papers in the bridging programme. Participants were in ongoing study (for at least one year) in a Bachelor of Health Science (any major). The methodology was qualitative in design, drawing extensively on a case-study approach to research the influences of the bridging programme. The method of data collection utilised was individual semi-structured interviews with former bridging students to ascertain their perceptions, views and experiences of the influence of a bridging programme, both historically and currently. In examining this unique context, information on the influences of bridging education was explored and the importance of bridging education, from the participant’s perspective, understood more clearly. This thesis and the research within revealed that the influence of the bridging programme began at the participant’s time of enrolment and continued into their undergraduate study and their lives. The bridging programme influenced the way participant’s interacted with a range of factors including: the institution; their undergraduate programme; with educators and peers; and with family, friends and others in society. Equally, it is acknowledged that these factors influenced the participant’s, facilitating or impeding their ongoing learning. The participants also identified several challenges (financial and relational) related to the influence of tertiary study which they faced. The research revealed the programme influenced their ongoing success and continuation in undergraduate study. The programme provided an effective bridge into tertiary education (academically, emotionally and socially). Participant’s acknowledged the influence on their cognitive and meta-cognitive growth and development. The range of tertiary leaning skills and knowledge gained and/or enhanced was considerable. Close links between the academic skills taught in the bridging programme and required in undergraduate study were evident. Positive improvements in confidence, self-efficacy and motivation were also attributed to the influence of the programme. Holistic personal development occurred as the skills and knowledge gained and developed were transferred and extended from academia into other areas of the lives of former bridging students and thus further influenced their family, personal friends and society. The influence of the bridging programme has enabled new opportunities, ways of being and employment to become more than a dream, but a reality which the participants continue to move towards. Overall, it could be claimed that the influence of the bridging programme was holistic. A series of recommendations are provided for theory, policy and practice. The significance for social issues and action are discussed and avenues for further research outlined.

Information use in clinical practice: A case study of critical care nurses' enteral feeding decisionsMarshall, Andrea January 2008 (has links)
Doctor of Philosophy (PhD) / Although registered nurses have a plethora of information sources available to assist them in making clinical decisions, how this information informs such decisions is not well understood. Through the work undertaken in this thesis a deeper understanding of information use in clinical practice is developed. Information use in clinical uncertainty is explored, specifically in the context of making decisions about enteral feeding practices within critical care environments. Instrumental case studies were used to access the information use processes of registered nurses working in an intensive care unit. Two case sites (a Level III intensive care unit in metropolitan teaching hospital and a Level II intensive care unit in a district hospital) were selected for the purpose of theoretical replication. Data were collected to inform specific issues. Concurrent verbal protocols (think aloud), observation and retrospective probing were used to explore documented clinical decisions and the information used to inform those decisions. Q sorting was used to determine the accessibility and usefulness of information available to participants and focus groups were used to explore senior nurse clinician’s perceptions of the authority of the identified information sources. A synthesis of findings from the two case sites highlighted three key issues. First, natural testimony (the use of personal communication to obtain information) was privileged over other, more formal sources of information however the veracity of the information obtained through natural testimony was not explicitly assessed. Registered nurses relied on the credibility of the person providing the information, leaving the information itself unchallenged. The clear reliance on information accessed through natural testimony, but the evident lack of critical evaluation of information obtained in this way, indicates a need for the development of strategies for the critical assessment of the accuracy of this clinical information. Second, the findings highlighted nurses’ use of clinical inquiry. Nurses used clinical inquiry to resolve clinical uncertainty as well as for logistic reasons. Participant’s use of inquiry was influenced by their approach to work, the impact of both organisational and personal perspectives on the perceived value of their work; and by models of clinical leadership where an investment in relational capital was considered a strategy to positively influence a culture of inquiry. Although organisational documents which are designed to ensure quality and consistency of patient care as required by current clinical governance strategies were considered useful, these document were not widely used as a primary source of information. The use of organisational documents, as well as the need to practice in concert with such documents, was identified as a factor negatively impacting on the development and support of nurses’ use of clinical inquiry. Third, findings addressed the usefulness of information for clinical decisions and the resolution of clinical uncertainty. The usefulness of information was influenced by its relevance to a clinical question or information deficit, and by the media used to convey the information. In general, print based media was considered more useful than other forms such as electronic documents. While original research was not considered useful, nurses valued research-based practice and responded positively to incorporating research into practice, particularly if research was pre-appraised by colleagues who were able to disseminate research findings to the clinical area and facilitate its use in clinical practice. This case study indicates that information use is less about individuals and the clinical context in which they are making decisions, and more about the social, cultural and organisational influences that shape decision making, and the information selected to support those decisions. The preference for natural testimony as information in decision making may, on first consideration, be viewed as undesirable in a work context that relies on accurate and consistent documentation. Determining the credibility of the information provider and the accuracy of the information itself is also challenging in an environment where this type of information and the approach to accessing it is selected for its ease of accessibility and the speed at which it can be applied. Yet, the pervasiveness with which nurses rely on others for information suggests verbal testimony is important in the context of clinical practice and highlights the need to develop a clearer understanding of why nurses privilege this information. Therefore verbal testimony must be considered carefully as a strategy for providing information, particularly research-based information and this study therefore highlights the need to develop strategies that enable those providing information to convey their expertise as a clinician as well as a user and provider of information. The organisational culture and work structures currently in place in Australia are unlikely to undergo significant change in the coming years, therefore their impact on information use warrants careful consideration. The nursing profession and the higher education sector aim to foster through inquiry, the independent, evidence-based practice of registered nurses. Health care organisations also highly value independent, evidence-based practice but also promote patient safety through use of current clinical governance strategies. While these two goals can be complimentary they also create tension when clinical governance strategies stifle inquiry and independent decision making of registered nurses. Ultimately, the current health care system in Australia and the wider community expect an evidence base for practice together with clinical governance strategies that promote safe practice. Nurses, as part, of this system must be accountable for both in the context of their clinical practice. We therefore need with some urgency to determine how to best balance these complementary and simultaneously competing ideals.
