▼ The goal of this thesis is to explore a simple and
general framework for domain analysis in ferroelectric thin films.
In this work I construct mathematical and numerical description of
complex ferroelectric systems and use it to advance our knowledge
and understanding of domains. I state that the main theoretical
tool we have employed is an appropriate Landau-Ginzburg-Devonshire
(LGD) model, and its time-dependent generalizations. I analyze four
types of domains - (i) 1800, (ii) 900, (iii) vortex-antivortex and
(iv) fractal. A nonlinear domain dynamics is observed in
intrinsically pinned ferroelectric films while growing fractal
domains occur under the influence of an external electric field. I
measure fractal Hausdorff dimension by detecting the edges of the
domain images by means of the standard Canny algorithm. Hausdorff
dimension which is computed numerically shows a very good
quantitative agreement with experiments. To understand dynamics, I
compute the areal velocity of the domains as a function of the
applied field and find different regions of nonlinearities that
qualitatively agree with experiments. I also generate
vortex-antivortex-vortex (V-AV-V) triplet by applying an
inhomogeneous transverse field in the x-y plane. A specific
boundary condition is used to maintain the sanctity of the vortex
states i.e. the net polarization in the boundary is always ensured
to be zero. I also use the Ginzburg-Landau-Devonshire free energy
theory to construct a set of time-dependent differential equations
in order to model the dynamics of interaction between the tip of an
Atomic Force microscope (AFM) and the surface of a ferroelectric
thin film. I obtain growth and nucleation pattern of ferroelectric
domains under the AFM tip. To conclude, the construction of an
appropriate domain model is an important step towards understanding
the technologically important ferroelectric materials. We have
confirmed our results by double-checking with experimental data and
also with other alternate theoretical approaches.

▼ Ph.D. University of Hawaii at Manoa 2013.
In this dissertation I examine Indigenous Knowledge Systems (IKS) and Western science, critically analyzing the underlying values of each, and exploring ways in which both systems can be utilized side by side. In general, Western science has arguably become the worldview utilized in dealing with the many complex multi-level issues of today.
Research has shown that as issues increase in both size and complexity, so does the need for cultural and intellectual diverse frames of reference for identifying solutions to problems. By necessity Indigenous peoples have developed their own science-based understandings of the world. Passed on through oral traditions, Indigenous peoples have both maintained and expanded their understandings over time. Until recently Indigenous worldviews have been forcefully removed and placed outside of the realm of science.
Focusing on Indigenous stories as scientific knowledge-wells and storytelling as a vital means of transmitting that knowledge, I discuss science through the stories of four Indigenous educators and practitioners. In addition, I highlight the importance of relationships: relationships to place, to each other, to the stories, and to the storyteller. In particular I examine relational accountability, a framework in which the researcher is held accountable to the people, research, and elements around him or her because of their strong foundational relationships to them. Using relational accountability as a base and stories and storytelling as the methodology, I argue that although IKS look and feel different than the colonizer's dominant Western science paradigm, IKS are supersaturated with scientific information that needs to be brought into the scientific discussions for policy and practice today.

▼ The stable isotope (SI) approach is widely used in ecological research to tackle problems such as delineating food web structure or tracing the migratory origins of various organisms. This thesis first tested the widely accepted assumption that SI ratios are fixed in an inert tissue, and then used the SI approach to infer the food web structure, from a marine top predator point of view, of a profoundly impacted marine ecosystem off southern Namibia. In bird research, it is assumed that SI ratios are fixed in feathers once they have completed their growth during moult. This assumption is crucial in determining where birds moult, and has been used to infer changes in the environment over time, as well as changes in the trophic levels of individuals. Recent comparisons of feathers collected from several penguin species during their annual moult have shown systematic differences between newly moulted and old feather SI ratios. I thus tested whether a change in SI ratios occurs as feathers age by comparing the carbon and nitrogen SI ratios of black and white feathers collected from captive, individually known African (Spheniscus demersus) and northern rockhopper (Eudyptes moseleyi) penguins at three occasions over a year. I found a clear trend for the rockhopper penguin feathers with new and old black feathers differing in their δ13C and δ15N values; this trend was not as clear for the African penguins. I then tested factors related to feather wear as a possible mechanism for differences in SI ratios between new and old feathers; these factors were feather reflectance and microstructure. In both penguin species, old black feathers reflected more light, and had a larger proportion of their barbs without barbules near their tips compared to new feathers. Feather wear may result in melanin leakage, which may explain the observed trends in the SI ratios between new and old pigmented penguin feathers. Differences in SI values were observed between species and may be a result of facility at which the penguins were housed, where one facility was exposed to more sunlight than the other, rather than the differences being a result of species. Although the differences observed were subtle, the state of feather wear (i.e. timing of feather collection within the moult cycle) should be considered in order to make accurate ecological inferences based on their SI ratios. Further research is needed to fully understand the phenomenon and to test whether the same process affects pigmented feathers of flying birds. I then used SI ratios to update our knowledge of resource partitioning among a marine top predator community in southern Africa, and to infer the marine food web structure in a Marine Protected Area off the southern Namibian coast. The Namibian Islands Marine Protected Area supports the most important breeding population of bank cormorants (Phalacrocorax neglectus; Endangered), and historically was important for two other Endangered seabirds: African penguins and Cape gannets (Morus capensis). Non-threatened marine top predators…

▼ Public claims about the “failure” of science teaching have a 100 year history, which is almost as long as science has existed as a subject in schools. These claims which have evolved to proclamations of a social “crisis” in the post war period have been based in various iterative assertions about the failure of school science to meet its assumed social function to induct young people into a modern scientific structural-economic or functional world view and hence to reproduce a technical class in society. Public discussions of the broader cultural value of science education and scientific humanism, in the education of the person and citizen have been rare. This may be interpreted as a response to the essentially subversive nature of scientific knowledge or the significance of the technical training function that secondary science education is required to perform. Science teaching has been institutionalised as value free, and the skills of science teaching defined in terms of practical epistemologies in various scientific domains. Studies of teachers’ habits of action, of interpretation, of belief and validatory belief have been rare, particularly juxtaposed to the experiences of their students in their classes. Studies of life in science classrooms have attended to teachers or students, rarely both and more rarely even the school as the unit of analysis. Such studies have been small in scale and very poorly funded compared to the numerous formal enquiries into declining enrolments in senior pre-professional subjects in secondary schools. It is a history of social enquiry that seems to be reproduced in each period at the point where the imperfection of the writers’ memory of their experiences in science classrooms meets the past inadequacies of documentation of practice.
The current small investigation takes its rise not from an interest in the so called facts about falling enrolments in senior science subjects or to establish a new theory of cause and effect, but from an urge to put together in a new way what everyone knows is there in science classes in the accounts of students and teachers, but not noticed. At Caby High School, an urban, multicultural secondary school, seeking to improve student participation and achievement in secondary education, my three collaborating science teachers and I were not looking for new facts but to better understand what is in plain view to them and their students in their everyday experience in junior science education. In that sense my considerations in this study were not scientific or hypothetical ones, to advance a kind of theory. I have not sought explanations of the supposed “failure” of science teaching in terms of what students fail to accomplish, expect or experience but rather to document what the students’ experiences and expectations are of science classes and how the teachers responded, not directly to the students’ expectations, but in terms of balancing both the social order to which the teachers are retrospectively…

▼ The means of producing information and the infrastructure for disseminating it are constantly changing. The web mobilizes information in electronic formats, making it easier to copy, modify, remix, and redistribute. This has changed how information is produced, distributed, and used. People are not just consuming information; they are actively producing, remixing, and sharing information, using the web as a platform for creativity and production. This is true of software development as well. It is frequently commented by programmers and researchers who study software development, that programmers frequently copy and paste code. Although this practice is widely acknowledged, it is rarely studied directly, or explicitly accounted for in models of software development. However, this attitude is changing as software becomes more ubiquitous, and software development practice shifts away from the formal models of software engineering, towards a post-modernist perspective. This study explores how source code snippets in programming books and on the web are changing software development practice. By examining program source code using clone detection algorithms, this study provides a comprehensive view of code copying across 6,190 PHP-language applications. These data are used to explore the concept of a “remix” method of software production, where software and systems are built out of copied and pasted snippets of code. These findings are contrasted against both traditional models of information production coming from informetrics (e.g., authorship, citation analysis), and models from software engineering (e.g., the Lego Hypothesis). Explanations for observed phenomena are discussed borrowing metaphors from linguistics, which provide a richer explanation of copy-paste programming than offered by the Lego Hypothesis. The focus and findings of this study ultimately point to a pressing demand for further research centered on the notion of <i>software as information</i>. Software and software repositories hold a large amount of information about how it was produced, and how it is used, adapted, and maintained. Software informatics is proposed as an organizing label to study the science of information, practice, and communication around software. It studies the individual, collaborative, and social aspects of software production and use, spanning multiple representations of software from design, to source code, to application.

▼ This study explores the information validation process of police investigators. The purpose of the research was to create a formal process model of the information validation process of a group of professional investigators. In this study I argue that the existence of such a model will help researchers in various disciplines by providing a baseline to which the validation process of other groups of information seekers can be tested and compared. The study subjects consisted of 45 police investigators and data was collected using 4 distinct methods including semi-structured interviews, talk aloud sessions, a controlled experiment, and a Joint Application Design (JAD) session. The research culminated in a new process model of the information validation process of police investigators. The study also provides a new research framework for the future study of information validation processes of various groups of information seekers. Several new discoveries emerging from the study include, but are not limited to, the findings that when validating new information, police investigator’s consider disparities between the behavioral, physical, visual, evidentiary, and potentially audible forms of information surrounding the information source and the investigator’s own personal knowledge base and experiential database. Other discoveries were that police investigators use their knowledge base and experiential database to create a virtual descriptive scenario or pre-disposition of what they expect to find before the validation process begins. They then use an abductive process through a questioning and information exchange process to test the details of their own scenario moving towards the best possible explanation of their observation. In summary the study provides a new model of information validation illustrating the entities, processes, and decisions that comprise the process as well as the relationships, inter-dependencies, and constraints that govern it. Using professional investigators as study subjects provides merit to the model as a baseline or foundation to which we can now begin to study and compare the information validation process of other information seekers to the new model.

ENGLISH ABSTRACT: This study seeks to analyse regionalism in theory as well as in practice with regard to the Southern African region. Its purpose is thereby twofold: Firstly, this work claims to make a contribution to critical and reflectivist theorising of regionalism. The study of regionalism remains highly dominated by rationalist theories focusing predominantly on states as regionalising actors as well as on formal inter-state frameworks and market-led processes of regional integration. The hegemonic status of these approaches reinforces a specific form of regionalism which is compatible with neoliberal practices in the world economy. In order to reveal shortcomings and normative tenets of conventional theories and to account for the complexity and multidimensionality of regional projects and processes, a combination of theoretical insights from Robert W. Cox’s Critical Theory (CCT) as well as from the New Regionalism(s) Approach (NRA) are proposed as the theoretical framework for the study. The second objective is to bring civil society as a regionalising actor into the debate. Focusing on the highly exclusive and elite-driven regional project pursued by the region’s most comprehensive inter-state framework, the Southern African Development Community (SADC), the study addresses the question, as to what extent civil society at the regional level can act as a transformative force in terms of people-centred socio-economic development and social equity.
After introducing crucial meta-theoretical, conceptual and methodological considerations, the major theoretical contributions to the study of regionalism are reviewed critically and a critical/reflectivist approach is proposed as an alternative to mainstream rationalist theorising. In a broad historical overview, the social, political, economic and cultural contexts which characterize the contemporary region of Southern Africa are discussed. Subsequently, four regional civil society organisations, namely the SADC Council of Non-governmental Organisations (CNGO), the Southern African Trade Union’s Co-ordination Council (SATUCC), the Economic Justice Network (EJN) of the Fellowship of Christian Councils in Southern Africa (FOCCISA) and the Southern African People’s Solidarity Network (SAPSN), are scrutinized with the intention to assess their transformative potential within SADC. The research conducted for the study is based on an eclectic employment of a combination of mostly qualitative methods, among them field research interviews, participatory observations as well as the analysis of primary and secondary sources/data. Two important conclusions can be drawn from this work: Firstly, an explicitly anti-reductionist and critical theoretical approach is seen as essential to account for the myriad of multi-level structural as well as agency-related factors influencing regionalism and regionalisation in Southern Africa. Secondly, the impact of regional civil society actors investigated in this study with regard to a more socio-economically inclusive…

▼ ENGLISH ABSTRACT: The fall of the Berlin Wall in 1989 ushered in a new era of globalisation and with it, intensified levels of global migration. The movement of people across increasingly fluid and penetrable boundaries has altered the demographic profile of European states and this cultural diversity has confronted contemporary Western liberal democracies with a unique set of challenges concerning the integration of diverse groups into society for the purpose of fostering cohesion and domestic stability. The effects of cultural diversity are not limited to demographics however, and this thesis focuses predominantly on the political and public responses that this phenomenon has evoked. The context of the Netherlands provides a particularly enlightening example of the way in which attempts to manage cultural diversity have stimulated intensive debate on immigration and integration topics, which have subsequently become firmly ensconced within public and political discourse. This ongoing debate in the Dutch context has brought to the fore wider questions pertaining to citizenship, national identity and culture. More importantly, these issues have exposed the limits of Dutch tolerance: increasingly restrictionist immigration and integration policy over the last two decades, and in the last 10 years in particular, has appeared incongruous with stereotypical perceptions of the Netherlands as an ultra-liberal and progressive paragon of multiculturalism.
This thesis therefore seeks to rework this image of the Netherlands by observing possible shifts in public attitudes towards immigrants and immigration in the context of considerably less favourable material circumstances, occasioned by the current global financial crisis. Attitudes towards Muslims in Dutch society are of particular interest to this research given the particular cultural and symbolic threat that Islam is considered to pose to liberal values. Realistic Group Conflict Theory provides a useful framework for analysing inter-group competition and conflict stemming from both material and non-material perceptions of threat. Whilst particular focus is accorded to the specific macro-economic conditions of the ongoing financial crisis for observing potentially shifting sentiments, this discussion is situated within a larger national debate about immigration and integration spanning two decades. Linking public perception data to analyses of Dutch integration and immigration policy, patterns of voting behaviour and the real effects of the financial crisis on the Dutch economy, the ultimate intention of this research, then, is to assess the prospects and overall “health” of liberal democracy in the Netherlands. The country‟s experiences in attempting to deal with cultural pluralism reveal that liberal democratic norms have not simply been entrenched as “givens” and they are subject to contestation and ambiguity. It is in attempts to address difference and “otherness” in society that the shortfalls of Dutch liberal democracy have been laid bare.

▼ ENGLISH ABSTRACT: This research reports on the phenomenon of preventable staff loss (human capital) in a South-African government department.
The research covered an analysis of biographical, occupational types and duration of job tenure data of 500 former employees who resigned over a ten-year period. Of these employees, 72 participated in a quantitative survey designed to test opinions around aspects such as career management, retention efforts and the resignation decision. Another 9 participated in telephone interviews.
The evolution of organizational theory over the last few centuries and the recent emergence of organizational systems theory are used as basis for, on the one hand, describing government departments in general as the type of organization under discussion and on the other to identify themes that point to possible avenues for diagnosis of the phenomenon.
Recent trends and technological developments leading to increasing scarcity and fluidity of the labour market are highlighted against the growing importance of the value of human capital and institutional knowledge as key components of achieving organizational goals.
The effects of South-African political developments after 1990 on talent management in general, and enterprise systems in particular, are covered.
The optimal implementation of talent management (as a component of organization-wide knowledge management strategies) is proposed as a possible solution.
AFRIKAANSE OPSOMMING: Hierdie navorsing doen verslag oor die verskynsel van voorkombare personeelverlies (Menslike kapitaal) in ‘n Suid-Afrikaanse staatsdepartement.
Die navorsing sluit ‘n analise van biografiese, beroepstipe en lengte van diens van 500 voormalige werknemers wat oor ‘n tien jaar periode bedank het, in. Van hierdie werknemers het 72 deelgeneem aan ‘n kwantitatiewe vraelys wat ontwerp is om opinies rondom aspekte soos loopbaanbeplanning, pogings om personeel te behou, en die bedankingsbesluit te toets. ‘n Verdere nege het deelgeneem aan telefoniese onderhoude.
Die evolusie van organisasieteorie oor die afgelope paar eeue en die onlange opkoms van organisatoriese sisteemteorie is as basis gebruik om eendersyds staatsdepartemente as organisasietipe in die algemeen te bespreek en andersyds sekere temas te identifiseer wat rigtinggewend kan wees in pogings tot diagnose en verdere ondersoek van die verskynsel.
Onlangse neigings en tegnologiese ontwikkelinge wat lei tot toenemende vloeibaarheid en skaarsheid in die arbeidsmark word beklemtoon teen die groeiende belangrikheid van die waarde van menslike kapitaal en institutionele kennis as sleutelkonsepte in die bereiking van organisatoriese doelwitte.
Die gevolge van Suid-Afrikaanse politieke ontwikkelinge na 1990 op die bestuur van talent oor die algemeen, asook die benutting van ondernemingstelsels (enterprise systems) in die besonder, word aangespreek. Die optimale implementering van talentbestuur as onderafdeling van organisasie-wye strategieë vir kennisbestuur word voorgehou as ‘n moontlike oplossing.

▼ ENGLISH ABSTRACT: The Japanese-African aid relationship has evolved since World War Two. The majority of studies on Japan’s role in Africa have focused on the economic aspect, while Japan’s aid relationship with Africa remains a relatively underexplored area of enquiry. This thesis aims to contribute to the study of Japanese-African relations by focusing on the role of aid in Japan’s involvement with the continent. The research question focuses on the evolution of Japan’s aid relationship with sub-Saharan Africa and the factors that have shaped this relationship. The study is qualitative and exploratory in nature and makes use mostly of secondary sources. Theoretically, the study analyses the aid relationship with reference to three sources of motivation for the provision of aid, namely economic, political and moral rationales. The findings of this study highlight the fact that, before 1990, Japan’s aid relationship with Africa was motivated by all three rationales. From an economic perspective, aid served as security for resources from Africa especially after the oil crisis of 1973. From a political perspective, Japan’s aid relationship served a number of objectives that changed over time. The study highlights these changes, suggesting that, from a political perspective, Japan’s aid in respect of Africa initially served to play a critical role in the Western camp in its anti-communist struggle on the continent. It was also used to curb criticism directed at Japan by African countries for its pro-Pretoria policy.
After 1990, Japan’s aid relationship with Africa from political perspective served Japan’s ambition to be recognised as a political power, most importantly to receive the support from Africa that would allow Japan to secure a permanent seat on the United Nations (UN) Security Council. From an economic perspective, it served to secure strategic natural resources for Japan that would sustain its growing economy and help to achieve its ambition of attaining global economic supremacy. From a moral perspective, the aid relationship served to promote a development path for Africa similar to that experienced in Japan’s Asian neighbourhood. Japan’s aid relationship with sub-Saharan Africa can be explained from a realist perspective, since the country’s national interests played a key role in the distribution of aid in this region. It has been important for Japan to maintain its momentum regarding global economic prominence and influence and for it to try to secure a permanent seat on the UN Security Council. By distributing aid to Africa, it has hoped to improve its chances of achieving its economic ambition and importantly its elevation to the Security Council. The study thus suggests that political ambitions have been the primary motivating factor in the distribution of aid in sub-Saharan Africa.
The areas for further investigation, as highlighted by the findings of this study, are as follows: Japan’s aid relationship with Africa remains a relatively new area of inquiry and more research could therefore be…

▼ ENGLISH ABSTRACT: The point of departure for this study was the wide-ranging furore in media publications regarding the pervasive decline in donor funding for civil society organisations in South Africa, as influenced by the recent global financial crisis, and the subsequent shutting down of a number of civil society organisations. The decision to embark on this study has its roots in the fact that civil society is an important feature in a democracy with regards to government responsiveness, accountability as well as citizen participation in democratic governance. In South Africa, particularly, this is important in light of the country’s fledgling democracy, and even more so, when considering the ruling party’s overwhelming political power resulting in a dominant party system.
The aim of this study was to find out what accounts for the plummet in donor funding, and the overriding question guiding this study was: Has the global financial crisis influenced civil society in South Africa? The broader question asked was: What are the challenges facing civil society organisations in South Africa? This study aims to assist in the evaluation of the potential role that civil society has played and continues to play in South Africa’s young democracy and what the implications would be for democracy if civil society organisations were hampered in these roles and continued to close offices. This study is explorative in nature and relied on qualitative data obtained from in-depth interviews conducted with two prominent South African non-governmental organisations; namely the Institute for Democracy and the Treatment Action Campaign. A key informant was selected and interviewed from each organisation. The findings of the interviews were operationalised through the lenses of Andrew Heywood’s (2007) conceptual theoretical framework, which puts forward five resources that civil society organisations need in order to exert their influence. While acknowledging the importance of all five resources, this study pays particular attention to financial resources received through international donor funding, for without financial resources it is difficult for an organisation to survive.
The findings of the interviews and the conclusions drawn underscored four realities: firstly that the decrease in funding is not limited to the organisations examined in this study, but civil society as a whole. The second reality rests on the fact that the global financial crisis has indeed influenced the Institute for Democracy and the Treatment Action Campaign in ways that are a cause for a concern, not only for the survival of the organisation, but also for the durability of South Africa’s young and at times fragile democracy. The third reality points to other challenges that have influenced donor funding, such as South Africa’s middle income status, a shift in donor orientation and focus and donor-specific problems. The fourth reality that was pointed out thrust this study into the conclusion that financial resources are the essential life-blood of…

▼ Saccharomyces cerevisiae var. boulardii is a probiotic strain of the baker’s yeast Saccharomyces cerevisiae. It has a long history of use in treating and preventing several kinds of diarrhea in human. Recently, scientists have drawn their attentions to use this probiotic yeast as a living drug delivery vehicle to the gastric intestinal tract (GIT). Several distinctive features of S. boulardii such as an optimal growth temperature at 37 ºC and better acidic tolerance enable active recombinant protein expression in harsh conditions. Human intrinsic factor (IF) is a glycoprotein secreted by gastric parietal cells and belongs to vitamin B12 (Cobalamin, Cbl) transport family. The gastric IF gene (GIF) encodes this protein. It is an essential protein for the proper absorption of Cbl in the terminal ileum, lacking of which results in vitamin B12 deficiency, especially common among the elders. This study aims to express active human IF from probiotic S. boulardii that can be combined with vitamin B12 forming B12/IF complex and absorbed by intestinal cells. To achieve these goals, a plasmid pSF-TEF1-TPI1-Blast-GIF was designed for S. boulardii transformation. Verification of recombinant IF was accomplished by SDS-PAGE, Western blotting and peptide sequence mapping by mass spectrometry (MS).
Experimental results indicated that the recombinant IF was not able to be synthesized in useful amount from S. boulardii using plasmid pSF-TEF1-TPI1-Blast-GIF. Transformation of the plasmid carrying GIF sequence brought significant phenotypic and metabolic modification to the host cells. PCR technique was found unsuccessful to verify the presence of correct plasmid, leaving uncertainty whether the correct plasmid was present in the transformants or not. Interestingly, an immunreoactive band at expected size (45 kDa) could be detected with rat polyclonal antibody in Western blotting. This band could be only detected from the supernatant when cells were grown with Cbl supplement, but shown to be exo-1,3-β-glucanase in MS protein sequencing. However, it is still possible that trace amount of recombinant IFs are secreted but cannot be detected due to MS sequencing limitations. Even though there was a contradictory result in Western blotting compared to that of MS sequencing, the excessive secretion of the exo-1,3-β-glucanase which may corrode yeast cell walls, may explain the different phenotype of transformants in comparison to host cells. This study indicated that not all genetic manipulation tools designed for S. cerevisiae are without problems for S. boulardii. More studies need to be carried out for successful heterologous IF protein expression with this probiotic yeast.

▼ The literature review dealt with the chemical and physical properties of chitin polymer and its degradation product glucosamine. Particular emphasis was given to studies on the analytical methods of determination of chitin from various products including gravimetrical, spectrophotometric and chromatographic methods.
The aim of this study was to optimize an analytical method to determine insect chitin and to apply the method to quantify chitin in whole insects and their soluble protein fractions. Two species of insects were selected: mealworm larvae (Tenebrio molitor) and cricket (Acheta domesticus). Whole insects and their protein fractions were treated with alkaline to remove protein. Chitin in de-proteined insect material was then hydrolysed into glucosamine using 6M HCl. Glucosamine from the hydrolysate was determined using chromatographic and spectrophotometric methods, where chromatographic method was optimized and validated.
UPLC-FLR method was specific for glucosamine and the UPLC system could separate two target peaks (glucosamine isomers: α and β). Glucosamine content was calculated using a calibration curve which showed excellent linearity in range 0.0033~24.0 ng/inj. with the determination coefficient more than 0.999 during the study period. The instrumental limit of detection and limit of quantification were 0.00095 ng/inj. (2 µL) and 0.0033 ng/inj. (7 µL), indicating a satisfied sensitivity. Recovery of glucosamine spiked to sample matrix (de-proteined cricket flour) following chitin hydrolysis was not satisfactory (~75%) using HPLC-FLR method, which indicated that spectrophotometric method gave chitin amount closer to the true value due to a higher recovery (>90%). Major findings on chitin amount was ~5% on dry matter basis in both mealworm and cricket. A small percentage of chitin was found in insect protein fractions extracted by 0.1M NaCl.

▼ This dissertation serves as a sort of historical road map on my journey to help secure not just computers, but the networks that connect them, and their sometimes critical mission, and the people that depend upon them.
We start with the most theoretically stimulating (and difficult to understand; yet most promising)
subject of the thermodynamic formalism of free energy. We investigate two algorithms; one to estimate the free energy observed by a system, and another algorithm that makes use of additional side information to estimate free energy with more precision and selectivity for classification. We demonstrate that the estimation of free energy can classify malicious network traffic as abnormal in absence of a given model.
The second chapter applies our free energy approach to a Boolean feature vectors for a notional cyber security system. In this chapter we describe how to establish upper and lower bounds of trust as a real number which can be used to help secure resource constrained systems. We also introduce the concept of trust decay, which is a range of real numbers.
The third chapter is an older journal paper that when combined with our theory of free energy may be useful in detecting collaboration between observed entities as well as estimate the channel capacity of some types of covert channels.
Last but not least is a chapter that I am particularly proud of for its novel approach to a particularly vexing problem in computer security: how to improve upon the ubiquitous password for user authentication. This work illustrates the level of detail required for scientific repeatability, which is entirely lacking in the field of cyber security today.

▼ Recently, an unknown myopathy has been observed in some Finnish broiler Pectoralis major muscle for the past 3 years and similar breast muscle defect have been found in several other countries as well. Wooden Breast is the term to describe this abnormality due to its macroscopically visible hard, bulging and pale area in the caudal part of the fillet.
This study aims to compare and measure some physical properties and chemical composition differences between Wooden Breast and Normal broiler breast muscle.
32 breast fillets of 38 days old Rose 508 broilers were sacrificed at the university experiment premises for evaluation. 20 breasts muscle were Wooden Breast affected, and the other 12 macroscopically Normal breast muscles served as Normal. In this experiment, measurement of sample physical properties (drip loss, cook loss, compression test, and Allo-Kramer shear force) and chemical composition (moisture, protein, and collagen content) were conducted.
As for the results, Wooden Breast had lower protein content and higher moisture content (P<0.05) than Normal; Wooden Breast had higher drip and cooking losses (P<0.05) than Normal; Wooden and Normal breast muscles did not differ in the initial and the ultimate pH; Wooden Breasts had similar compression (24h) and shear force (cooked) results compared to Normal breast (P>0.05); No quantitative difference in total or soluble collagen were detected (P>0.05).

▼ Wooden Breast is a myopathy seen on chicken breast muscles in the last years, causing economic losses. It is associated with hardness and paleness of the muscle, necrosis, fibrosis and macrophage infiltration. The aim of this study was to investigate the differences in sarcomere length and tensile strength between normal and Wooden Breast in chicken. For the sarcomere length measurements 20 unaffected chicken breasts and 21 Wooden Breasts were used. For half of each group electrical stimulation was applied. Sarcomere length was measured in four different locations of each breast: cranial and medial area, surface and depth. The tensile test experiment involved three experimental groups, with 20 samples for each group: unaffected, with focal lesion and with diffuse lesion. Samples were cut from the surface layer of cranial and medial area of every chicken breast, both on longitudinal and transversal direction of the muscle fibers.
Results showed that Wooden Breast syndrome has a significant effect on sarcomere length, leading to increased lengths in the affected muscles compared with the normal muscles (p<0.05). There was less lengthening of the sarcomere as result of electrical stimulation in WB muscles compared with normal chicken breasts (p<0.05). The difference in sarcomere length between WB and Normal was smaller in the surface layer of the muscle in comparison with the depth layer. There were no significant difference between the mean values of tensile strength in Normal samples and Focal WB samples, but significantly higher values in Diffuse WB samples (p<0.0001). The Diffuse samples yielded significant higher tensile strength when they were stretched parallel with muscle fiber direction, compared with cross-sectional direction of stretching (p<0.05). In the Diffuse cases the cranial area had increased tensile strength compared with the medial area, indicating an increased level of WB severity in the cranial area compared with medial area.

▼ The purpose of this research was to study the overall effects of teaching scientific argumentation in conjunction with content knowledge in an 8th grade science classroom. The goals were to determine if students could: a) learn argumentation
as a concept, b) learn to argue well at the same time as they learned new content knowledge, and c) improve how they applied that knowledge to situations that required science understandings. The study made use of explicit instruction in argumentation,
scaffolds that helped students develop their arguments, and oppositional groupings to aid students in learning to argue and in developing higher level and complete arguments. Students participated in four main argumentative sessions spanning electricity
and magnetism content-knowledge-related topics. Three of these arguments were strictly science-based, while the final argument made use of a socially relevant scientific topic. The arguments that students developed were rated quantitatively based on
their structure and level of content knowledge included. The arguments were analyzed qualitatively based on argument and reasoning patterns. Students completed an interview that was analyzed for themes regarding student perceptions regarding argument and
the learning experiences. The findings from the data indicate that over the course of the unit, students developed greater skill in the construction of their arguments. Students developed more complete products, used more content knowledge in a
meritorious manner, and reasoned more effectively. Students progressed in their arguments as a result of explicit teaching of argumentation coupled with scaffolding sheets to help them produce quality arguments. Statistically significant improvements
were made in almost every case. The thematic nature of the argument and reasoning patterns showed that students were reasoning more effectively and thinking critically about what they were doing and about the science that supported their efforts to
support their claims. The student perception interviews showed that students appreciated the way using argumentation as a learning tool, as well as a specific part of science, helped them to develop a deeper understanding of the content. The participants
enjoyed convincing others that they were right while they used information they developed in class and through research to make persuasive arguments.

▼ In August 2005, Hurricane Katrina made landfall along the Gulf Coast, becoming infamous for the destruction it wrought to communities from Louisiana to Alabama. Most notably, it caused massive flooding in New Orleans and surrounding parishes by breaching the levee system. The storm’s impact on the region’s population, buildings, and collective psyche is impossible to measure. As was the case with other Gulf Coast institutions in the path of Hurricane Katrina, the region’s libraries also suffered extensively. Through examination of the available literature and first-hand accounts of library professionals, this thesis examines the impact that Hurricane Katrina had on libraries in southeastern Louisiana, the New Orleans metropolitan area, and Southern Mississippi. It also considers the role disaster plans played in preserving select libraries’ collections as well as some of the problems occurring with their implementation during the disaster. It was discovered that library disaster plans are designed to mitigate small, localized disasters, not those on the scale of Hurricane Katrina. It was also found that large scale disasters, like a hurricane or earthquake, render such plans ineffective, though action taken by library staff before and immediately afterward can make some difference. The thesis concludes with a list of recommendations for library disaster planning in the future.

▼ The "Technical Debt" metaphor is gaining recognition in the software development community, not only to communicate the debt to the non-technical stakeholders but also to maintain the long term health of the software project. The idea is that software practitioners accept compromises in the project in some magnitude to meet demand in other dimensions. The compromises in the system incur a "debt" which has to be repaid at some point for the long term health of the project. If the debt remains unpaid, it could incur more additional costs, in terms of software that is harder to change and more error prone. This pain is most evident to the software practitioners, as they are the ones' who have to deal with these problems at the code level. We have conducted an interview study of software practitioners to analyze and understand how they face this debt and how they manage it. The result of this study identifies the characteristics, causes, and approaches for management of technical debt. As a result of analysis of the data for this study we also present several models of the cause and effect of different types of technical debt. These models also provide an understanding upon which approaches to track, measure, quantify and monitor technical debt can be developed.

▼ The Open Biomedical Ontology (OBO) Foundry initiative is a collaborative effort for developing interoperable, science-based ontologies. The Basic Formal Ontology (BFO) serves as the upper ontology for the domain-level ontologies of OBO. BFO is an upper ontology of types as conceived by defenders of realism. Among the ontologies developed for OBO use, there are those which have been ratified, and those currently holding the status of candidate. To maintain consistency between ontologies, it is important to establish formal principled criteria that a candidate ontology must meet for ratification. Members of the OBO Foundry have expressed interest in using OntoClean to help construct BFO compliant domain ontologies. OntoClean is a system that decomposes the notion of sortal into criteria for deciding when subsumption can hold between classes. OntoClean primarily includes three components, based on the notions of Rigidity, Identity, and Unity. The methodology for integrating the OntoClean and BFO approaches to constructing consistent ontologies has been clarified by this dissertation. A formal integration between BFO, the Relation Ontology of BFO (RO), and OntoClean is given. The informal aspects and differing formalisms within and between the theories are analyzed and integrated within the axioms and theorems of one first-order system put forth in the dissertation. To set the foundation for this work, the categorical units of <i>type</i> and <i>property</i> of BFO and OntoClean, respectively, are unified under class. The modal logic axioms that OntoClean's theory of Rigidity is expressed within are interpreted and reformulated in our system, where axioms connecting it with BFO's categorical unit <i>type</i> is given. Central to this work is the axiom that a type is a class that is Rigid, i.e., a class whose definition is fundamental to the existence of the members of the class. A unity criterion for a class is a way in which certain parts of a member of the class are related such that they form the whole member. Our reformulation of this work focuses on the notion of the underlying unifying relation. As opposed to the informal approach taken by OntoClean, we express the notion that a class is <i>unified under</i> a relation as a meta-predicate defined by a definition schema. An identity criterion for a class is a test by which a member of the class can be re-identified. However as given in OntoClean, the notion of <i>identity criteria</i> is ontologically ambiguous. A formalization is given that provides a mapping to processes during which identity is confirmed. The reformulations of Unity and Identity are discussed in terms of <i>Material Entity</i> subtypes of BFO's theory. The integration work and resulting formal system affords a theoretically sound ontological foundation. A method for evaluating and standardizing candidate OBO Foundry ontologies is developed atop this foundation, where the method focuses on BFO's integration with OntoClean's notion of Rigidity. The method is…

▼ Companies offering services on the Internet have led corporations to shift from the high cost of owning and maintaining stand-alone, privately-owned-and-operated infrastructure to a shared infrastructure model. These shared infrastructures are being offered by infrastructure service providers which have subscription, or pay-on-demand, charge models presenting compute and storage resources as a generalized utility. Utility based infrastructures that are run by service providers have been defined as "cloud computing" by the National Institute of Standards and Technology. In the cloud computing model the concerns of security and privacy protections are exacerbated due to the requirement for an enterprise to allow third parties to own and manage the infrastructure and be custodians of the enterprises information. With this new architectural model, there are new hybrid governance models designed to support complex and uncertain environments. The cloud also requires a common infrastructure that integrates originally separate computing silos. Privacy and security policy awareness during provisioning and computing orchestration about data locality across domains and jurisdictions must be able to obey legal and regulatory constraints. Commercial use of the Internet for electronic commerce has been growing at a phenomenal rate while consumer concern has also risen about the information gathered about them. Concern about privacy of data has been rated as the number one barrier by all industries. The purpose of this dissertation is to perform an empirical study to determine if existing privacy assessment instruments adequately assess privacy risks when applied to cloud infrastructures. The methodology for determining this is to apply a specific set of privacy risk assessments against a three cloud environments. The assessments are run in the context of a typical web based application deployed against cloud providers that have the five key cloud tenets—on-demand/self-service, broad network access, resource pooling, rapid elasticity, and measured service.

▼ This is an exploratory study examining the effect that the images contained in Academic Library Web Portals have upon users’ perception in three areas: the users’ perception of the portal’s usability, the users’ perception of the effectiveness of the portal and the users’ perception of the quality of the information found through the portal. The crucial concept of “image pertinence” (Hildreth 2004) was introduced in this study. Pertinent images are images that pertain to the textual information found on their mutual Web page. This research was conducted in three phases. In the first phase, a study was conducted comparing the effect that high-image-pertinent academic library portals and low-image-pertinent academic library portals have on the users’ perception of the portals’ usability. One hundred undergraduate students searched three sets of matched-pairs of high-image-pertinent and low-image-pertinent academic library portals for the answers to two ten-question information retrieval exercises constructed of questions similar to those asked at an academic library’s reference desk. Data collected and statistically analyzed included: the scores from the pairs of information retrieval exercises, the time to complete the information retrieval exercises, the mouse clicks used to complete the information retrieval exercises, the users’ perception of the use experience, the users’ perceptions of the information quality and the users’ statement of portal preference. In the second phase of the study, student subjects rated 50 images drawn from a 250 image pool for their appropriateness in an academic library Web portal. These image ratings were examined to determine if there was evidence of image gender preference and an overall preference for images of people over images not of people. In the third phase of the study, experts in the field of libraries and information studies were surveyed as to their perception of the usability of the same library portals the student subjects used in the first part of the study. The experts’ usability ratings of the portals were compared to the students’ usability ratings.

▼ A major issue in current music information retrieval (MIR) research is the lack of empirical studies of users and real-life music information seeking behavior. In particular, our poor understanding of real-life queries is an impediment to developing MIR systems that meet the needs of real users. This study aims, by an empirical investigation of real-life queries, to contribute to developing a theorized understanding of how people seek music information. This is crucial for informing the design of future MIR systems, especially the selection of potential access points, as well as establishing a set of test queries that reflect the real-life music information seeking behavior. Queries are collected from an online reference website and coded using content analysis. The taxonomies of needs and information features are established by an iterative coding process and the intercoder reliability of the categories is tested by standard measures. The empirical associations between the needs and features are measured by the co-occurrences among them. Queries with known answers are qualitatively examined in order to determine the accuracy of selected information features provided by users and to gain insight into use of these features in music information queries. This study found that (i) most of the queries analyzed are known-item searches, (ii) most contain a wide variety of kinds of information, (iii) much of this information is false, inaccurate, or uncertain, and (iv) despite these inaccuracies and uncertainties many queries are successful. A theory from pragmatics is suggested as a partial explanation for the unexpected success of inaccurate queries. Based on this study some recommendations for improving MIR systems can be made: (i) incorporating user context in test queries, (ii) employing terms familiar to users in evaluation tasks, and (iii) combining multiple task results are recommended. Information about related multimedia works and applying attributive/referential readings of descriptions in IR may also help improve the current MIR systems.

▼ In this thesis, the fundamental experimental observation is that, on the Internet and other networks, traffic seems to concentrate quite heavily on some very small subsets. The main result in here is that this phenomenon is not, in general, related to the popular “heavytailed” phenomenon, but is a consequence of the negative curvature of the network. The mathematical analysis and simulation results confirm this striking traffic pattern specific to negatively curved networks from both the theoretical and practical points of view. Furthermore, this thesis addresses another fundamental question: if congestion does not necessarily occur at vertices with high degree, nor at the so-called highly connected “core,” then what are the congestion points? It is shown that the congestion points are the points relative to which the network has low moment of inertia. That single point relative to which the network has a well-defined minimum is referred to as the centroid, the point through which most of the traffic transits. Probably the most important result as far as protocol design is concerned is that load balancing can be achieved by a routing table designed on the basis of a virtual network in which the link weights have been adjusted to correct the curvature from negative to positive. The latter mathematical technique is reminiscent of the Yamabe flow and the Poincaré conjecture. The practical implementation of this concept on the ns-2 network simulator indicates a significant reduction of the congestion.

▼ Seminal works on leadership, including those in librarianship define a traditional model of interaction between leaders and followers without reference to the information technology-driven environment. In addition, remote leadership indicates a different model from the traditional model, one that is focused on the interaction of leaders and their staff through digital technology. Although leaders still use face-to-face interaction, due to varied work schedules or job responsibilities, they also recognize the need to lead employees remotely. Leadership studies in library literature have not addressed how library leaders use information technology to lead employees remotely, nor have these studies addressed remote leadership and remote employees, except for some articles on telecommuting. As a result, this research was conducted to address this gap, providing an exploratory foundation of emergent patterns of remote leadership with its associated leadership dimensions rooted in personality traits, behaviors, and skills. Quantitative and qualitative data were obtained from a small sample size of academic and public-library leaders in the United States who participated in a Web-based survey designed specifically for this study, limiting generalizations. Factor analysis was the principal methodology used to obtain findings. Its composite factor scores were also used in the <i>t</i>-test and chi-square analyses. This study identifies some emergent patterns of remote leadership in the library and information-science field, exploring whether library leaders use information technology to be effective remote leaders in a technology-driven environment, and whether existing leadership attributes could be identified as part of the remote-leadership model. Because this study’s findings indicated that library leaders are not quite the traditional leader but are not fully integrated into remote leadership, it becomes apparent that they would function with a blend of both face-to-face and electronic interactions, due to the nature of library work. Additionally, this research revealed underlying issues and challenges faced by library leaders as they transition from a traditional-leadership model to a blended model of face-to-face and remote leadership. Future research could include increasing the sample size and response rate to conduct factor analysis properly, and conducting longitudinal studies.

▼ <i>Scope and Method of Study.</i> Aerospace Security Stakeholder Qualitative Interviews. Interests internal and external to the United States could wreak havoc by manipulating, impairing, or data mining the digital information being exchanged by aircraft and controllers in the proposed NextGen air traffic control system. The purpose of this study is the analyze potential security risks imposed by implementing the active network technologies utilized by ADS-B in NextGen, and more specifically the air-to-air, air-to-ground, and satellite-to-air links used. The purpose of this study was to provide a risk analysis of the NextGen active network compared to industry standards and best practices for information systems security. Data obtained through interviews was used to determine the effective security categorization and provide a risk analysis of the ADS-B portion of the proposed NextGen active network. <i>Findings and Conclusions.</i> Based on this research, there are both significant similarities and differences between the NextGen Active Network and industry standard computer networks. Both the ADS-B and computer networks operate in a wireless environment. Both are designed to move information between local devices, though the ADS-B devices may cover 200-300 miles at altitude where the computer networks are designed to cover a range of 200-300 feet. Both have methods of insuring a high level of data integrity using FEC, CRC, 24-bit parity, or MAC codes. It is at this point that the similarities diverge, as the missions of the two networks are markedly different. Specific conclusions and recommendations cover the differences between the designed mission requirements of NextGen and existing computer security standards focusing on the security objectives within the Federal Information Security Management Act of 2002 and other pertinent government standards and industry best practices.

▼ Due to recent advances in data collection techniques, massive amounts of data are being collected at an extremely fast pace. Also, these data are potentially unbounded. Boundless streams of data collected from sensors, equipments, and other data sources are referred to as “data streams”. Various data mining tasks can be performed on data streams in search of interesting patterns. This dissertation studies a particular data mining task, <i> clustering</i>, which can be used as the first step in many knowledge discovery processes. By grouping data streams into homogeneous clusters, data miners can learn about data characteristics which can then be developed into classification models for new data or predictive models for unknown events. Data streams clustering calls for data clustering techniques that require only a single pass access of data and a very short processing time per data point. Moreover, the system will likely have to discard data that have already been viewed. Therefore, suitable techniques are needed to incrementally update the clustering model. We propose a novel method called POD-Clus (Probability and Distribution-based Clustering) that complies with the above requirements for data streams clustering. This dissertation covers two paradigms for data streams clustering. In <i>clustering by example</i>, data points collected from the same data source can have different cluster assignments. Alternatively, <i>clustering by variable</i> treats each stream as one unit and all data points from the same stream must stay in the same cluster. We demonstrate that POD-Clus is applicable to both paradigms. POD-Clus also handles situations when clusters evolve. Cluster evolutions are relevant to data streams clustering since the nature of clusters from the boundless streams may change considerably over time. We include the following types of cluster evolutions: cluster appearance, cluster disappearance, cluster splitting, and cluster merging. The methodologies in this dissertation are grouped into (a) clustering by example without evolution, (b) clustering by example with evolution, (c) clustering by variable without evolution, and (d) clustering by variable with evolution. We conducted experiments on POD-Clus and compared against recent data streams clustering algorithms. Results show significant improvements in clustering results using POD-Clus as compared to competing algorithms.

▼ Geospatial data processing and visualization has matured into an important research area. Although a number of tools and devices exist for acquiring raw data, visual analysis and exploration of raw datasets (census data or LANDSAT imagery) acquired in this manner remains a challenge. One crucial tradeoff in such visualizations is choice between the quantity of data presented, and important details that are associated with individual (or clustered) data instances. This dissertation presents solutions to three topical problems in the field of geospatial visualization. The first solution is an extension to the <i>CGA Shape Grammar</i> that allows a domain scientist to quickly author glyph-based visualizations on a geospatial domain. This work extends the grammar framework by adding new commands that process geospatial databases and provide geo-referencing functionality for the glyphs. The second solution presents a method for visualizing Route Maps that preserves the overview, and provides detail information at points of interest along the route. The optimal placement of the detail lenses is calculated with the help of a backtracking based optimization algorithm. Usability studies that validate the usefulness of this approach are presented. The third solution provides a novel method for designing time-constrained tours for tourist activities. The described approach combines a time-dependent scheduling method for creating the trip itinerary with a novel layout algorithm to display sightseeing routes at given attractions. Route details, including turn points and landmarks around the route, are shown in detail while preserving the overall path shape and local context relationships. Several examples of trip brochures created with the system are also provided.

▼ In HCI, CSCW and Ubicomp, making people's presence and activities visible as a design approach has been extensively explored to enhance computer mediated interactions and collaborations, being developed under the rubric of "awareness"[28], "social transluence"[35], "social activity indicators"[2], "social navigation"[23], etc. Although name varies, the central ideas are largely the same. By making social presence and activities more visible or perceivable, they provide social context for members to make sense of the situations and guide their activities more informatively and appropriately. In this dissertation, I introduce an approach called <i>social context displays,</i> which uses graphical representations to depict people's presence and activity information in a <i>group</i> level and is shared by the <i>group.</i> Like other works, it is aimed to provide contextual information to enhance computer mediated interactions by making people's presence and activity visible, but unlike other works, it emphasizes groupness where everyone in the groups sees the same information with the same view. The aim of this dissertation is to examine social context displays in use and contribute new abstractions for understanding for how making social information more visible will work in general. Through our first hand experience with user-centered design and empirical investigations in real settings of four social context displays, both instrumental and expressive, we uncovered not only how they provide social context to inform actions and decisions, but also how members perform and manage their self- and group-representations through the display. Drawing on Goffman's performance framework, we suggest <i> performance through social context displays</i> as a new model to reason and design social context displays and similar work.

▼ The growing complexity of interactions between computers and networks makes the subject of network security a very interesting one. As our dependence on the services provided by computing networks grows, so does our investment in such technology. In this situation, there is a greater risk of occurrence of targeted malicious attacks on computers and networks, which could result in system failure. At the user level, the goal of network security is to prevent any malicious attack by a virus or a worm. However, at the network level, total prevention of such malicious attacks is an impossible and impractical objective to achieve. A more attainable objective would be to prevent the rampant proliferation of a malicious attack that could cripple the entire network. Traditional Intrusion Detection Systems (IDSs) focus on the detection of attacks at the individual nodes, after a malicious code has entered individual machines in a network. However, repeated failures of conventional IDSs have led researchers to develop methods that integrate detection systems in networks and use their collective intelligence to defend against malicious attacks. Such approaches utilize the synergistic power generated by the network, as nodes share prior and current knowledge of detected attacks and related information with other nodes. This dissertation investigates the practical application of a cooperative approach, used to defend computer networks against attacks from external agents. In this dissertation I focus on the detection of metamorphic NOP (No OPeration) sleds, which are common in buffer overflow attacks, and the role of topology on the rate of spread of a malicious attack. The aim of this study is to use the results to provide recommendations that can be utilized to develop optimal network security policies.
