Abstract:

The present study evaluated the effectiveness of two instructional approaches for remedial reading courses at a community college. The instructional approaches were strategic reading and traditional, textbook-based instruction. The two research questions that guided the quantitative, quasi-experimental study were: (a) what is the effect of strategic-reading instruction on the reading performance of community college students in a developmental reading course and (b) what is the effect of traditional, textbook-based instruction on the reading performance of community college students in a developmental reading course? The sample consisted of 64 participants. Two groups of students participated in the study: (a) the experimental group (n = 32), who received the strategic-reading instruction, and (b) the control group (n = 32), who received the traditional, textbook-based instruction. Students took the Nelson-Denny Reading test as a pretest and posttest to determine the effectiveness. The null hypotheses for H1 and H2 were rejected because the results of the paired t-test indicated strategic-reading instruction and traditional, textbook-based instruction have a statistically significant positive effect on students’ performance on the Nelson-Denny Reading Test Form G. Further, the one-way ANOVA test showed there is not a statistically significant difference between the difference scores of the students who received strategic-reading instruction and the students who received traditional, textbook-based instruction. The findings show that both methods of instruction are equally appropriate for the remedial reading course.

Abstract:

Introduction: Irrigation is regarded as having a key role in one of the main goals of endodontic treatment, the killing and removing bacteria from the infected root canal. Different methods and techniques have been used to deliver irrigating solutions and to facilitate the effectiveness of irrigation. The purpose of this in vitro study was, by using quantitative real-time PCR to determine the effectiveness of two irrigation and cleaning systems in removing multispecies oral biofilms from root canals. Methods: Fifteen extracted human molars were instrumented to size #15/.02 and then cleaned with the GentleWave System (GW; Sonendo Inc, Laguna Hills, CA). The teeth were autoclaved to provide the same sterile baseline. The molars were filled with mixed plaque suspended in brain-heart infusion broth and centrifuged to help the bacteria spread all over the root canal system. After two weeks of incubation, samples were divided randomly into two treatment groups and instrumented into size #15/.04 (GW) and #35/.04 (PiezoFlow group) under needle irrigation with sterile water. The teeth were then cleaned either with GentleWave System or ProUltra PiezoFlow Active Ultrasonic System (Dentsply Tulsa, Tulsa, OK) using 3% NaOCl, 8% EDTA and sterile water as irrigants. Root canals were sampled with paper points before and after instrumentation (S1, S2) and after GW or PF cleaning (S3). Quantitative real-time PCR was performed, the presence of microorganism in the samples was determined by using universal bacterial, a genus specific and species-specific primers. Statistical analysis was performed using the Mann-Whitney U test with the significance level set at P < 0.05. Result: A highly significant bacterial reduction was recorded for both groups (P < 0.001). GW group showed a significantly higher reduction than the PF group of total microbes (P < 0.01), Enterococcus faecalis (P < 0.01) and Streptococcus species (P < 0.05). GW resulted predictably in high reduction of over 99% of the microbes in every canal, whereas in the PF group the reduction of microbes varied between 87% and 99.99%. Conclusion: While both systems demonstrated effective reduction of intracanal bacteria, a high level of over 99% was more predictably achieved in the GW group.

Abstract:

Rheumatoid Arthritis (RA) is a disease in which the body has "turned on itself", with its immune system attacking mobility. In RA, an immune mechanism attacks and destroys the joints and limits mobility, in some circumstances to the point of needing replacement of joints. The aim of this research is the development of a less costly, widely accessible, passive sensing technology that provides a quantitative assessment of RA and that monitors the therapeutic effectiveness on joint-debilitating diseases. The proposed solution relies on a quantitative evaluation of human gestures. Such a quantitative assessment supports the comparison between the motion capabilities of a patient and that of a healthy person, using a kinematic model of the human skeleton. Criteria for the classification of severity were established, and tables were generated to classify the levels of severity as a function of the measurements extracted from processed videos of a subject performing predefined movements. This research project, while contributing a new tool to the process of classification of RA level of severity, opens the way for using widely accessible digital imaging for diagnosing and monitoring the evolution of the illness. Replacing MRI or HRUS with a cheaper and more accessible technology would have a major impact on health care services. From the clinical point of view, the proposed techniques based on digital images processing combined with a monitoring approach based on infrared images that was previously developed may provide a utility of care for patients with RA, as well as an alternative and automated approach for early detection of RA and active inflammation at a critical time.

Abstract:

How to measure risk is an important question in finance and much work has been done on how to quantitatively measure risk. An important part of this measurement is evaluating the measurements against the outcomes a procedure known as backtesting. A common risk measure is Expected shortfall for which how to backtest has been debated. In this thesis we will compare four different proposed backtests and see how they perform in a realistic setting. The main finding in this thesis is that it is possible to find backtests that perform well but it is important to investigate them thoroughly as small errors in the model can lead to large errors in the outcome of the backtest
Hur man mäter risk är en viktig fråga inom den finansiella industrin och det finns mycket skrivet om hur man kvantifierar finansiell risk. En viktig del i att mäta risk är att i efterhand kontrollera så att modellerna har gett rimliga estimeringar av risken denna procedur brukar kallas backtesting. Ett vanligt mått på risk är Expected shortfall där hur detta ska göras har debatterats. Vi presenterar fyra olika metoder att utföra detta och se hur dessa presterar i en verklighetstrogen situation. Det vi kommer fram till är att det är möjligt att hitta metoder som fungerar väl men att det är viktigt att testa dessa noga eftersom små fel i metoderna kan ge stora fel i resultatet.

We introduce the Social Stock Exchange (SSE), by presenting its work, structure and brief history. The main goal of the SSE is to promote accountability and transparency in the relationship between the donors (Social Investors) and NGOs, which allows for a privileged access to data and information about the projects listed. Hence, this study exploits all the information made available by the SSE and constructs two original models in order to measure the effectiveness of the projects listed in the SSE in a transparent, verified and mensurable manner. Furthermore, these two measures are a first attempt to overcome two main challenges concerning the study and the practice of NGO/NPO effectiveness: the ambiguity of the term “effectiveness” and the lack of empirical evidence.

Abstract:

In contemporary American society, the nonprofit board is accountable for ensuring that an organization has sufficient resources to carry out its mission. Filling the gap between demands for services and the resources to meet them is often a struggle for small, local nonprofit organizations. This hermeneutic phenomenological study examined how board members of small, local nonprofits in the focal community perceive organizational effectiveness. Understanding the nature of nonprofit organization effectiveness according to board members contributes to understanding how those accountable meet their organizational objectives. A review of the literature revealed that nonprofit effectiveness involves the action of contributing and the motivation behind the action, both of which are associated with trust and reciprocity. Guided by social constructivism, this study employed a qualitative analysis of repeated iterations of semiotic data from board members (n = 30) and text analysis of organizational mission statements (n = 21), generating thick descriptions of the board members' understanding of effectiveness. Findings were derived from successive coding iterations starting with the raw data, through locating text related to specific codes, to verifying relationships among codes, and incorporating researcher reflection. The analysis revealed that strategies focused on developing reciprocity and mitigating mistrust among board members contribute to board members' perceiving their organizations as effectively achieving their objectives. The study's findings support positive social change by informing social scientists and members of local nonprofit boards of the perceived gap between services demands and the resources to meet them among board members.

Eccles, Stephen David. "Quantitative evaluation of contract strategies for construction." Thesis, University of Sheffield, 2000. http://etheses.whiterose.ac.uk/3494/.

Full text

Abstract:

A contract strategy is, in broad terms, the legal-managerial framework adopted by the client of a construction project for carrying out that project. There is a view that projects are often procured using inappropriate contract strategies and that the associated financial consequences are significant. Following a review of previous research, it was concluded that there was scope to develop a decision methodology that utilised quantitative techniques. A prototype model was developed to facilitate the application of the quantitative approach. The model computes probabilistic cost and time measures of a project's performance for each contract strategy that is evaluated. Several industrialists were invited to evaluate the principles of the quantitative approach. From the fourteen industrialists interviewed, six simulated an application of the quantitative approach. Despite initial scepticism, the potential value of the quantitative approach was recognised. The six industrialists who performed example applications of the quantitative approach indicated that, in their view, the approach was workable. In response to the findings of the empirical study, an upgraded version of the model was designed. This version also addressed several intellectual compromises which had been made in the development of the prototype model. The refined model is applied to two example projects in order to demonstrate the potential utility of the quantitative approach and also to provide guidance on how to apply the model. It is acknowledged that the quantitative approach does not single out the most appropriate contract strategy for any given project. However, it is believed that the quantitative approach is most suited to deal with the decision problem's inherent complexities and is most likely to minimise the risk of irrational contract strategy decisions. It is therefore concluded that an improved understanding of contract strategy selection may result, especially on a personal level, from continued application of the quantitative approach.

Teaching & Learning
Ed.D.
In recent years, foreign language program evaluation has gained greater attention among language educators, program administrators, and evaluators. Increased demands for demonstrated program performance, often motivated by external forces, such as accreditation pressures and decisions regarding the allocation of funding, have led to heightened focus on foreign language program evaluation practices, methodologies, and results. Despite this increased attention, there are few published evaluation studies within the field of foreign language learning that have examined foreign language program effectiveness over time. This longitudinal study was designed to quantitatively investigate the performance of one Japanese university English for Academic Purposes (EAP) program over the 20-year span of the program’s existence. Quantitative evaluation methodologies and advanced statistical procedures were utilized to examine changes in student English proficiency, as measured by the Institutional Test of English as a Foreign Language (TOEFL ITP) and English achievement, as measured by four semesters of EAP course grades, as students progressed through the two-year program. Twenty cohorts of students (cohort n-sizes ranging from approximately 250 to 550 students) were included in this study. The comprehensive data set included three repeated-measures of the TOEFL ITP and four English achievement grade point averages (GPAs) for each of the 20 cohorts. The research questions for this expansive longitudinal study addressed two levels of inquiry. First, at the program-global level, this study sought to investigate patterns of English proficiency change within and between cohorts across the life of the program, and the extent that programmatic events and external influences might have impacted those patterns. For this investigation, TOEFL ITP results for three proficiency domains—listening, grammar, and reading—were chronologically charted for the 20 cohorts and time-series analyses were conducted. The results indicated that all cohorts demonstrated significant gains in the three proficiency domains by the end of the two-year program. However, the overall trends across the program’s 20-year history revealed gradual negative trajectories for grammar and reading proficiency. Events that were hypothesized to have influenced proficiency patterns were tested, including (a) the addition of a new department specialization, (b) changes to department admissions, (c) the entrance of students who experienced new national reforms at the secondary education level, and (d) department expansion. While listening proficiency patterns were unaffected, grammar and reading proficiency trends were negatively impacted by the start of the new specialization and changes to admissions procedures. The entrance of students who had experienced secondary educational changes had an initial negative impact on the grammar trend, but positive grammar and reading proficiency trends emerged from that point onward. It was speculated that these events, as well as larger population trends impacting Japanese universities, led to gradual shifts in program student demographics, which contributed to the observed changes in proficiency patterns. Also of interest was an examination of the concept of English achievement coherence—or the extent that student English achievement, as measured by English course grade point averages (GPAs)—can be used to assess course interrelatedness. English course GPA data was used to statistically derive three rival achievement coherence metrics. These metrics were then tested separately, using hierarchical linear modeling techniques, to examine the extent that achievement coherence might serve to mediate any proficiency variation observed across the 20 cohorts. There were no significant findings for two of the metrics tested, while the third metric was found to have a significant negative effect for reading proficiency. This finding directly contradicted the hypothesized outcome that a greater amount of coherence would serve to facilitate proficiency development. Given the significant negative reading trend that emerged across the life of the program, this result might suggest that larger influences affecting student demographic changes could outweigh any potential facilitative effects of coherence on proficiency outcomes. Following the program-global analyses, the second level of inquiry was at the cohort-specific level. Individual cohorts that had demonstrated comparatively high and low listening and reading proficiency gains were selected for follow-up analyses. The aim was to examine if differences in coherence at the cohort level might account for the contrastive proficiency gains attained. For each target cohort, a recursive path model, including the program’s 16 English courses and final proficiency outcome, was tested to examine English achievement interrelatedness and contributions to the final proficiency outcome. A greater number of significant paths and larger final model R2 coefficient would suggest more coherence. Additionally, for each target cohort, grade residuals analyses using linear regression methods were conducted to investigate grading consistency at the course level. A greater number of outlying grade cases could indicate that the course assessment schemes were not followed, which would suggest less cohort coherence. The results of these analyses for the pairs of contrastive listening gain and reading gain cohorts were compared, but no significant differences were found. While these analytical methods were determined to be useful for ongoing formative evaluation processes, the resulting measures were likely too broad to capture any meaningful differences in coherence between cohorts at the program-global level.

Abstract:

Autonomous visual navigation algorithms for ground mobile robotic systems working in unstructured environments have been extensively studied for decades. Among these work, algorithm performance evaluations between different design configurations mainly involve the use of benchmark datasets with a limited number of real-world trails. Such evaluations, however, have difficulties to provide sufficient statistical power for performance quantification. In addition, they are unable to independently assess the algorithm robustness to individual realistic uncertainty sources, including the environment variations and processing errors. This research presents a quantitative approach to performance and robustness evaluation and optimisation of autonomous visual navigation algorithms, using large scale Monte-Carlo analyses. The Monte-Carlo analyses are supported by a simulation environment designed to represent a real-world level of visual information, using the perturbations from realistic visual uncertainties and processing errors. With the proposed evaluation method, a stereo vision based autonomous visual navigation algorithm is designed and iteratively optimised. This algorithm encodes edge-based 3D patterns into a topological map, and use them for the subsequent global localisation and navigation. An evaluation on the performance perturbations from individual uncertainty sources indicates that the stereo match error produces significant limitation for the current system design. Therefore, an optimisation approach is proposed to mitigate such an error. This maximises the Fisher information available in stereo image pairs by manipulating the stereo geometry. Moreover, the simulation environment is further updated in association with the algorithm design, which include the quantitative modelling and simulation of localisation error to the subsequent navigation behaviour. During a long-term Monte-Carlo evaluation and optimisation, the algorithm performance has been significantly improved. Simulation experiments demonstrate that the navigation of a 3-DoF robotic system is achieved in an unstructured environment, while possessing sufficient robustness to realistic visual uncertainty sources and systematic processing errors.

A tool that measures the effectiveness of software project management can be used to identify strengths and weaknesses, and guide improvement to practices in order to increase the chances of project success. The Software Project Management Effectiveness (PME) Metric is one such tool that has shown promise in this area of software engineering. To discover how promising the metric is, nine software practitioners participated in this research and assisted with measuring projects they recently worked on. A strong correlation between the PME metric and project success was identified. The software practitioners also provided feedback on the usefulness and applicability of the PME metric. Seventy-five percent of the software practitioners stated that they would use the metric on the next project they worked on. This research has found that the PME metric should be considered for use by project managers who continuously want to improve and deliver successful software projects.

Abstract:

Several tools exist for root cause analysis (RCA). Despite this however, many practitioners are not obtaining the quality improvement desired. Those turning to literature for guidance would find most of the information resides in case studies with anecdotal outcomes. Since 5 Whys analysis has been one of the more pervasive tools in use, this study sought to add to the root cause analysis body of knowledge by investigating tool support factors. While studied in conjunction with 5 Whys, the support variables lend themselves to other root cause analysis tools as well. The purpose of the study was to utilize a 2 x 2 factorial design to determine the significance and effect on RCA effectiveness, of using a 5 Whys trained facilitator and action level classification. During the study, problem solving teams at service centers of a North American electric repair company conducted analysis with or without a trained facilitator. Additionally, corrective actions were or were not categorized by defined levels of ability to impact defect prevention. The dependent variable of effectiveness was determined by scoring from a weighted list of best practices for problem solving analysis. Analysis showed trained facilitators had significant effect on problem solving solutions, while classification had minimal

Abstract:

This MEng (Master of Engineering) research thesis evaluates the capabilities and limitations of line-scan thermography for the non-destructive evaluation of composite structures containing hidden defects. In simple terms, line-scan thermography is a state-of-the-art technique in which a focused line of thermal energy is transmitted into a material. Line-scan thermography has great potential for the rapid and low cost non-destructive inspection of composite structures for aircraft, automobiles and ships. In this project, theoretical research exploring the heat transfer physics was undertaken in conjunction with experimental studies to develop an optimum inspection regime for line-scan thermography. The capability of line-scan thermography to detect impact damage in carbon/epoxy laminates was experimentally investigated in Chapter 3. From the impact side, in all materials, line-scan thermography overestimated the size of the impact damage whereas flash thermography underestimated the size. There was a close relationship between the ultrasonic profile and the line-scan thermographic thermal response curve. New experimental data has been produced and analysed for the ability of line-scan thermography to determine the defect as well as the defect size. It was found that line-scan thermography was able to distinguish back drilled holes, but it was not possible to determine accurate defect sizing due to the depth of the holes from the inspected surface and the limitations associated with the line-scan thermographic apparatus itself. There was excellent correlation between the C-scan ultrasonics intensity curves and the line-scan thermographs as well as excellent correlation with the theoretical results. The relationship between line-scan thermography and foreign body objects were experimentally investigated for carbon/epoxy composites. A major limitation found with line-scan thermography is its limited depth penetration, which is highlighted in the foreign object study using 6 mm and 13 mm diameter Teflon® discs and 13 mm Teflon® strips embedded in carbon/epoxy laminates. Depth penetration allowed only 2 mm resolution for the 13 mm diameter discs and 1.5 mm resolution for the 6 mm discs in a composite panel. The results of the investigation of stainless steel shim objects in carbon/epoxy laminates reveal that line-scan thermography is capable of determining their presence and size close to the surface. There was also excellent correlation between the ultrasonic response curve and the line-scan thermographic intensity curve. The results of the investigation of thermoplastic film foreign body objects in carbon/epoxy laminates show that at present line-scan thermography does not have the capability to determin e such defects. Experimental results show that line-scan thermography is capable of detecting large voids, back drilled holes, some foreign body objects, and impact damage. However, the ability of line-scan thermography to measure the defect dimensions is dependent on the size and type of damage, the distance from the line source, the depth of the defect, and the type of composite material.

Abstract:

Business processes are the backbone of organisations used to automate and increase the efficiency and effectiveness of their services and prod- ucts. The rapid growth of the Internet and other Web based technologies has sparked competition between organisations in attempting to provide a faster, cheaper and smarter environment for customers. In response to these requirements, organisations are examining how their business processes may be evaluated so as to improve business performance. This thesis proposes a generic framework to expand the applicability of various quantitative evaluation to a large class of business processes. The framework introduces a novel engineering methodology that defines a modelling formalism to represent business processes that can be solved for a set of performance and optimisation algorithms. The methodology allows various types of algorithms used in model-based business pro- cess improvement and optimisation to be plugged in a single modelling formalism. As a part of the framework, a generic modelling formalism (MWF-wR) is developed to represent business processes so as to allow quantitative evaluation and to select the parameters for the associated performance evaluation and optimisation. The generic framework is designed and implemented by developing soft- ware support tools using Java as object oriented programming language combining three main modules: (i) a business process specification mod- ule to define the components of the business process model, (ii) a stochas- tic Petri net module to map the business process model to a stochastic Petri net, and (iii) an algorithms module to solve the models for various performance optimisation objectives. Furthermore, a literature survey of different aspects of business processes including modelling and analy- sis techniques provides an overview of the current state of research and highlights gaps in business process modelling and performance analy- sis. Finally, experiments are introduced to investigate the validity of the presented approach.

Abstract:

Antipsychotic medications are ubiquitous in the treatment of psychosis. However, relief from positive symptomatology comes at a price. Extrapyramidal side-effects such as drug-induced parkinsonism (DIP) are common and superficial similarities between features of parkinsonism and those of psychosis hinder efforts to calibrate dosages. The boundary between psychopathology and drug-induced disorder is a major conceptual issue in psychiatry. Instrumental assessment promises the opportunity to more accurately gauge this boundary. Three hypotheses were developed: that instrumentation has a role in the assessment of DIP, that bradykinesia is the predominant feature of DIP, and that cognitive and subjective features of parkinsonism are present in DIP. Instrumentation procedures were selected to objectively asses the three major features of parkinsonisms: bradykinesia, rigidity, and tremor. Subjective ratings of symptomatology associated with psychosis and antipsychotic mediation were taken. All the measures used were evaluated empirically relative to standard observer rating criteria and the constructs underlying the assessments were examined. The instrumental assessment techniques demonstrated moderate to high accuracy though most did not display significant advantages over clinical rating procedures. However, a role was proposed for performance measures in regular monitoring of bradykinesia. Stronger support was found for the latter two hypotheses. Results indicated that a greater degree and prevalence of abnormality relative to the control group was present in bradykinesia than the other features of parkinsonism. Empirical evidence demonstrated the presence of a cognitive deficit in behaviour associated with the presence of parkinsonism. The evidence from the study also bears on issues of drug tolerability. Support was provided for suggestions that the atypical antipsychotic, clozapine, has a uniquely low liability to induce parkinsonism.

Abstract:

The Scalable Coherent Interface (SCI) is an IEEE standard that defines a hardware platform for scalable shared-memory multiprocessors. SCI consists of three parts. The first is a set of physical interfaces that defines board sizes, wiring and network clock rates. The second is a communication protocol based on undirectional point to point links. The third defines a cache coherence protocol based on a full directory that is distributed amongst the cache and memory modules. The cache controllers keep track of the copies of a given datum by maintaining them in a doubly linked list. SCI can scale up to 65520 nodes. This dissertation contains a quantitative performance evaluation of an SCI-connected multiprocessor that assesses both the communication and cache coherence subsystems. The simulator is driven by reference streams generated as a by-product of the execution of "real" programs. The workload consists of three programs from the SPLASH suite and three parallel loops. The simplest topology supported by SCI is the ring. It was found that, for the hardware and software simulated, the largest efficient ring size is between eight and sixteen nodes and that raw network bandwidth seen by processing elements is limited at about 80Mbytes/s. This is because the network saturates when link traffic reaches 600-700Mbytes/s. These levels of link traffic only occur for two poorly designed programs. The other four programs generate low traffic and their execution speed is not limited by interconnect nor cache coherence protocol. An analytical model of the multiprocessor is used to assess the cost of some frequently occurring cache coherence protocol operations.

Abstract:

Airburst projectiles increase the effectiveness of air defense, by forming clouds of small pellets. In this work, in order to evaluate the effectiveness of airburst projectiles, Single Shot Kill Probability (SSKP) is computed at different burst distances by using three lethality functions defined from different measures of effectiveness. These different measures are target coverage, number of sub-projectile hits on the target and kinetic energy of sub-projectiles after burst. Computations are carried out for two different sub-projectile distribution patterns, namely circular and ring patterns. In this work, for the determination of miss distance, a Monte Carlo simulation is implemented, which uses Modified Point Mass Model (MPMM) trajectory equations. According to the results obtained two different distribution patterns are compared in terms of effectiveness and optimum burst distance of each distribution pattern is determined at different ranges.

Abstract:

Image registration is the process of aligning two images such that their mutual features overlap. This is of great importance in several medical applications. In 2008 a novel method for simultaneous T1, T2 and proton density quantification was suggested. The method is in the field of quantitative Magnetic Resonance Imaging or qMRI. In qMRI parameters are quantified by a pixel-to-pixel fit of the image intensity as a function of different MR scanner settings. The quantification depends on several volumes of different intensities to be aligned. If a patient moves during the data aquisition the datasets will not be aligned and the results are degraded due to this. Since the quantification takes several minutes there is a considerable risk of patient movements. In this master thesis three image registration methods are presented and a comparison in robustness and speed was made. The phase based algorithm was suited for this problem and limited to finding rigid motion. The other two registration algorithms, originating from the Statistical Parametrical Mapping, SPM, package, were used as references. The result shows that the pixel-to-pixel fit is greatly improved in the datasets with found motion. In the comparison between the different methods the phase based algorithm turned out to be both the fastest and the most robust method.

Abstract:

The work presented here utilises features of laser generated ultrasound for the detection of defects in solids. Ultrasound is generated noncontactively by this method and likewise many of the detection devices used do not require direct coupling to the test pieces, thus acoustic pulses with high frequency components are able to be produced and monitored on a range of samples. Steel samples coated with between 3 and 7mm of plasma-transferred arc depositions are examined for bond quality via measurements of attenuation caused by porosity in the coatings, found to be related to weld current. Surface breaking cracks, (of depth < 3mm), in such claddings are quantitatively detected by a method which utilises Rayleigh pulses. A two sided automated scanning system is described which examines samples for subsurface defects. Results from the examinations of a dural test piece, plasma sprayed steel bars and carbon fibre composite samples are presented. Resolution of defects is shown to be within 0.5mm for a 1mm thick section of the composite material. A second scanning technique, requiring access to only one sample face, is presented which employs an interferometer for detection and is thus a truly remote system. Laminar flaws are modelled using flat-bottomed holes, the dimensions of which are measured using the resonance of the bodies. A theoretical investigation using various boundary conditions suggests possible applications for quantitative NDE of structures with well defined natural vibration frequencies. The propagation of acoustic transients in plates is also examined. Possible future work concerning laser/ultrasonic NDE is discussed.

Abstract:

The studies presented here evaluate the biliary, parenchymal and vascular enhancement effects of two T1-shortening liver-specific contrast agents, Gd-BOPTA and Gd-EOB-DTPA, in Magnetic Resonance Imaging (MRI) of healthy subjects and of patients. Ten healthy volunteers were examined with both contrast agents in a 1.5 T MRI system using three-dimensional gradient echo sequences for dynamic imaging until five hours after injection. The enhancement of the common hepatic duct in contrast to the liver parenchyma was analyzed in the first study. This was followed by a study of the image contrasts of the hepatic artery, portal vein and middle hepatic vein versus the liver parenchyma. While Gd-EOB-DTPA gave an earlier and more prolonged enhancement and image contrast of the bile duct, Gd-BOPTA achieved higher maximal enhancement and higher image contrast for all vessels studied during the arterial and portal venous phases. There was no significant difference in the maximal enhancement obtained in the liver parenchyma. In a third study, another 10 healthy volunteers were examined with the same protocol in another 1.5 T MRI system. Using signal normalization and a more quantitative, pharmacokinetic analysis, the hepatocyte-specific uptake of Gd-EOB-DTPA and Gd-BOPTA was calculated. A significant between-subjects correlation of the uptake estimates was found and the ratio of these uptake rates was of the same magnitude as has been reported in pre-clinical studies. The procedure also enabled quantitative analysis of vascular enhancement properties of these agents. Gd-BOPTA was found to give higher vessel-to-liver contrast than Gd-EOB-DTPA when recommended doses were given. In the final study, retrospectively gathered datasets from patients with hepatobiliary disease were analyzed using the quantitative estimation of hepatic uptake of Gd-EOB-DTPA described in the third study. The uptake rate estimate provided significant predictive ability in separating normal from disturbed hepatobiliary function, which is promising for future evaluations of regional and global liver disease. In conclusion, the differing dynamic enhancement profiles of the liver-specific contrast agents presented here can be beneficial in one context and challenging in another. Diseases of the liver and biliary system may affect the vasculature, parenchyma or biliary excretion, or a combination of these. The clinical context in terms of the relative importance of vascular, hepatic parenchymal and biliary processes should therefore determine the contrast agent for each patient and examination. A quantitative approach to analysis of contrast-enhanced liver MRI examinations is feasible and may prove valuable for their interpretation.

Abstract:

We’ve found that Porter’s five forces framework is useful tool to analyze industry’s competitive forces and to shape organization’s strategy according to the results of the analysis. However, in reality this framework is rather analytical tool, used by managers to better understand the industry they operate in, than strategic choice and decision-making technique. Porter’s Five Forces model, in the form it prevails now, provides the static view onto the industry structure and conditions. Therefore, it has significant limitations, and requires further improvement and development as well as combination with other techniques.

Full text

Abstract:

This study aims to enhance the understanding of destination management system (DMS) effectiveness and its evaluation. Upon review of the literature, it was established that DMS effectiveness and its evaluation has not yet been researched adequately. Informed by an interpretive approach, this study contributes to research particularly by investigating what constitutes effectiveness and explores the aspects (factors and relationships) that need to be considered in a holistic DMS effectiveness evaluation. Based on a qualitative case study strategy, this study adopts a comprehensive approach that considers multiple stakeholder groups� perspectives. The research evidence is collected through a case-study of the Egyptian DMS experience (the Touregypt project). The Touregypt project gives insights to the understanding of three DMS cases that have not been researched before in DMS literature: first, an actual DMS application in a developing country; second, a public and private sector partnership experience; and third, a failed DMS experience (the system has failed in the course of this research).Prompted by the interpretive approach, this study tried to explore DMS effectiveness based on the perspectives, attitudes and experiences of the multiple stakeholder groups (Hesse-Biber and Leavy 2010). Accordingly, the empirical data was collected through a multi-method approach that includes interviews, observation, archival document analysis (including Touregypt forum analysis), and website analysis. Data has been analyzed guided by discourse analysis, complemented with the general inductive approach of Miles and Huberman (1994). Following an interpretive theory-building strategy, the analyzed data has been further interpreted in the light of prior theories of DMS and information systems research, particularly the Delone and MacLean IS effectiveness theory (1992, 2003, and 2004).The main contribution of this study to knowledge is a theory based model that enhances the understanding of DMS effectiveness evaluation. The suggested model identifies the aspects (factors and relationships) that need to be considered when evaluating the effectiveness of DMS. Also, the results of this study give insights to the understanding of DMS effectiveness by shedding light on what constitutes effectiveness and the possible relationship between such constructs.

Full text

Abstract:

This thesis discusses the outcomes of four years of research. The main purpose was to determine the influence of self-evaluation on school effectiveness and investigate any relevant issues. The qualitative research began with an extensive literature search to examine the body of knowledge which already existed and set the planned empirical work within the relevant theoretical context. This provided a stimulus for a set of research questions which helped express the intellectual puzzle. Data was gathered using a questionnaire which was completed by class teachers from the researcher's primary school and interviews which were administered initially to a group of primary head teachers from a small Scottish local authority. It became apparent that this sample was limiting so some Irish head teachers with an interest in self-evaluation and a group of educationalists from a variety of European countries were included. The results highlighted a number of links between self-evaluation and the features of effective schools and these have been fully explored in the dissertation. The findings indicated that there was a perception by many that self-evaluation does have a significant influence on school effectiveness and the extent of this depends on factors such as leadership which affects the level of morale, ownership and commitment to change. Good leadership can help develop a positive climate of trust and professional respect. Effective schools are happy communities characterised by high expectations of pupil achievement, ownership, reflection and a focus on the quality of learning and teaching. The research underlined the difficulties of measuring school effectiveness, the need for honesty and rigour when self-evaluating and the problems associated with insider research. Participants tended to link performance indicators with development planning and target setting and considered that such indicators contributed to the management of change by providing a standard set of criteria within a helpful framework to give teachers control and a degree of autonomy. Although accountability should not be the main purpose, self-evaluation was perceived to provide a means of contributing to school effectiveness by making policies and practices public. The thesis compares previous research with the views and experiences of practitioners and concludes with a series of recommendations arising from the study.

Abstract:

Approved for public release; distribution is unlimited
The Joint Technical Coordinating Group for Munitions Effectiveness desires a standardized toolbox and methodologies for evaluating weapons accuracy. Using statistical distributions, a method is presented for both unguided and Global Positioning System-guided munitions. The statistics used to describe a sample of weapons firings will not only describe the weapons’ accuracy, but will also be utilized by the Joint Weaponeering System to calculate the weapons’ effectiveness against specified targets. Since the precision of the inputs and statistics used to describe the accuracy of the weapons is sensitive, it is imperative that the inputs are accurately modeled as they can lead to drastically different effectiveness results. Analysts must also carefully consider the assumptions used in the application of specific statistical distributions. The toolbox and methods presented here illustrate the differences among techniques and the pros and cons of each.
