Bryant, Rebecca E. H. "Discovery and decision : exploring the metaphysics and epistemology of scientific classification." Thesis, University of Edinburgh, 1997. http://hdl.handle.net/1842/21657.
Full textAbstract:
This thesis comprises an interdisciplinary examination of the phenomenon of scientific classification. The major aims of the thesis are two-fold: To show that scientific classification comprises a mixture of metaphysics and epistemology. To illustrate that the psychological explanation-based account of categorisation is an appropriate model for scientific as well as for lay classification. I begin by characterising the doctrine of Objectivism which provides the philosophical backdrop for traditional accounts of categorisation in both philosophy and psychology. I illustrate some of the shortcomings of Objectivism and propose an alternative doctrine in its place - internal or experimental realism. This alternative doctrine forms the philosophical backdrop for my own account of (scientific) classification. Next, I provide a short history of theories in the psychology of categorisation. I argue that there has been a shift from very tightly defined, inflexible and context-insensitive accounts (the classical view) to much more flexible, context-sensitive and human-oriented accounts (the explanation-based view). I go on to examine the criticisms which an objectivist philosopher, Georges Rey, has levied against work in the psychology of categorisation. I then put forward for my own positive account of scientific classification. This incorporates a number of claims: that classification involves more than a reflection of metaphysics, that human beings (and so epistemology) make an active contribution to the classificatory process, that the dividing line between metaphysics and epistemology is blurred, that there are problems with applying the objectivist doctrine of essentialism to scientific classification and as a result of the foregoing points, that the explanation-based account of categorisation is a suitable model of classification by scientific experts. The material which I use in support of these claims comes from three case studies in the history and sociology of science and from a number of philosophical arguments.

Full textAbstract:
Many academic decision makers rely on quantified ranking measures to estimate the quality of journal publications. The aim of this study was to map journals in Information Systems (IS) with regard to their topic and their rank and determine whether there is a relationship between the scope of a journal and its rank. The study used content analysis, applying both qualitative and quantitative methods.
The results of the analysis show the existence of relationships between the journal rank, the research area, and the type as well as significant differences in ranking on the three lists. The findings illustrate that ranking measures, as indicators for the quality of research published in a journal ought to be considered only in the context of a particular research area and scientific community.

Full textAbstract:
With the significant advancementstaking place in the last three decades in the field ofInformation Technology (IT), we are witnesses of an era unprecedented to the standards that mankind was used to, for centuries. Having access to a huge amount of dataalmost instantly,entails certainadvantages. One of which is the ability to observe in which segments of their expertise do scientists focus their research. That kind of knowledge, if properly appraised could hold the key to explaining what the new directions of the applied sciences will be and thus could help to constructing a “map” of the future developments from the Research and Development labs of the industries worldwide.Though the above statement may be considered too “futuristic”, already there have been documented attempts in the literature that have been fruitful into using vast amount of scientific data in an attempt to outline future scientific trends and thus scientific discoveries.The purpose of this research is to try to use a pioneeringmethodof modeling text corpora that already hasbeen used previously to the task of mapping the history of scientific discovery, that of Latent Dirichlet Allocation (LDA)and try to evaluate itsusability into detecting emerging research trends by the mere use of only the “Abstracts” from a collectionof scientific articles.To do that an experimental set is being utilized and the process is repeated over three experimental runs.The results, although not the ones that would validate the hypothesis, are showing that with certain improvements in the processing the hypothesis could be confirmed.

Full textAbstract:
Missing Links explores relationships between objects. It is an empirical exercise in equivalence and divergence, an experiment in the visual nomenclature of enumeration and classification and a dissertation on the materiality of the construction of systems of thought. It is concerned with the manufacture and production of particular histories through the formal analysis of fifty specimens. The specimens, or objects, under investigation are constructed from recycled corrugated cardboard, water-activated brown tape and hot glue. These materials are transformed and renewed through a series of repetitive processes and activities including cutting, slicing, rolling, joining, gluing
The material is receptive and provisional in nature. The specimens exist as a series of models, one made after the other, each made in response to the one before, and as thus present an unfolding of thoughts and material experiences. They represent a genealogy of the imagination ; creating relationships and dialogues within and between external physical manifestations. The study of natural history informs this collection with particular reference to the nineteenth century work of Charles Darwin. In his attempts to understand the temporal arrangement of the natural world in The Origin of the Species, Darwin posited the notion of infinite change. This project is inspired by Darwin's emphasis of the sheer multiplicity of living objects, their complexity and the possibility of a transformational and material history. The objects in Missing Links were produced in response to the prolific nature of the natural world, its endless variations and ability to produce exquisite material adaptations. As a collection, they contain, support and enact a layered history, an archive of process and a document of action. Missing Links also references the procedures of the laboratory - the facilitation of controlled conditions under which experiments, documentary exercises and data collection and collation can take place. It is the merging of these two realms and activities that lies at the heart of the project. The synergy of the artistic world and the scientific activities the project employs highlight similarities and discontinuities between seemingly disparate practices. This is a productive coupling; facilitating interesting juxtapositions between objects and ideas and signalling the potential for the collection to coalesce in a multiplicity of orders in response to the systems of thought that contain and constrain it.

LeBien, John. "Automated Species Classification Methods for Passive Acoustic Monitoring of Beaked Whales." ScholarWorks@UNO, 2017. https://scholarworks.uno.edu/td/2417.
Full textAbstract:
The Littoral Acoustic Demonstration Center has collected passive acoustic monitoring data in the northern Gulf of Mexico since 2001. Recordings were made in 2007 near the Deepwater Horizon oil spill that provide a baseline for an extensive study of regional marine mammal populations in response to the disaster. Animal density estimates can be derived from detections of echolocation signals in the acoustic data. Beaked whales are of particular interest as they remain one of the least understood groups of marine mammals, and relatively few abundance estimates exist. Efficient methods for classifying detected echolocation transients are essential for mining long-term passive acoustic data. In this study, three data clustering routines using k-means, self-organizing maps, and spectral clustering were tested with various features of detected echolocation transients. Several methods effectively isolated the echolocation signals of regional beaked whales at the species level. Feedforward neural network classifiers were also evaluated, and performed with high accuracy under various noise conditions. The waveform fractal dimension was tested as a feature for marine biosonar classification and improved the accuracy of the classifiers.

Full textAbstract:
The basic idea of this paper is to outline a cross-curricular approach between mathematics and science. The aim is to close the often perceived gap between formal maths and authentic experience and to
increase the students’ versatility in the use of mathematical terms. Students are to experience maths as logical, interesting and relevant through extra-mathematical references. Concrete physical or biological correlations may initiate mathematical activities, and mathematical terms are to be understood in logical contexts. Examples: physical experiments can lead to a comprehensive understanding of the concept of functions and of the intersection of medians in triangles. Biological topics can lead to the concepts of similarity and proportion as well as to the construction of pie charts. In the European ScienceMath Project a variety of teaching modules was developed and tested in secondary schools.

Schmidt, David. "Knot Flow Classification and its Applications in Vehicular Ad-Hoc Networks (VANET)." Digital Commons @ East Tennessee State University, 2020. https://dc.etsu.edu/etd/3723.
Full textAbstract:
Intrusion detection systems (IDSs) play a crucial role in the identification and mitigation for attacks on host systems. Of these systems, vehicular ad hoc networks (VANETs) are difficult to protect due to the dynamic nature of their clients and their necessity for constant interaction with their respective cyber-physical systems. Currently, there is a need for a VANET-specific IDS that meets this criterion. To this end, a spline-based intrusion detection system has been pioneered as a solution. By combining clustering with spline-based general linear model classification, this knot flow classification method (KFC) allows for robust intrusion detection to occur. Due its design and the manner it is constructed, KFC holds great potential for implementation across a distributed system. The purpose of this thesis was to explain and extrapolate the afore mentioned IDS, highlight its effectiveness, and discuss the conceptual design of the distributed system for use in future research.

Full textAbstract:
University forests are very important in academic forestry education. They are not only used for the in-forest teaching but also serve for scientific research and public education for people to gain knowledge of forests. Besides these functions, the university forests can also provide social services, such as camping and recreation. People can go into the university forests to enjoy the nature and relax.
Taking Beijing Forestry University as an example, this paper will describe the system of university forests in China, their categories, and their roles in forestry education, research and social services. Furthermore, this paper will also explain the development and management system of university forests, and key challenges to the university forests in the future.

Neue Technologien und Praktiken – wie z.B. die Kommunikation über soziale Netzwerke wie Facebook – können die Entstehung und Erhaltung sich selbst organisierender Wissensgemeinschaften fördern. Diese Gemeinschaften gehören häufig unterschiedlicher Kulturen an und unterscheiden sich daher in den ihnen zugrunde liegenden Werten, Einstellungen und Vorgehensweisen, welche wiederum die Akzeptanz von Bildungstechnologien beeinflussen können. Inwieweit neue Technologien in einem gegebenen kulturellen oder interkulturellen Kontext akzeptiert werden und sich so tatsächlich dazu eignen, Wissensgemeinschaften zu unterstützen, wird erst seit wenigen Jahren untersucht.

Full textAbstract:
Content:
One of the main challenges of the tannery industry chain is to reduce the use of biocides and restricted substances and at the same time increase efficiency with the available products. Such conduct must
permeate suppliers and the tanneries in order to obtain better results, diminish the biocide resistance dissemination, optimize costs and be ecologically friendly. In this sense, we present herein an updated
review and discussion of the scientific and technological literature on the aspects involving the action of fungicides in tannery industry and how the application of this knowledge can reduce application of biocides and restricted substances in the tanning process. We have organized a review by consulting the databases PUBMED, Web of Science, Science direct, and all literature with excellence scientific support available. The review focused on: (i) Fungal diversity involved in wet-blue biodeterioration; (ii) Mechanisms of action of fungicides; (iii) Fungicide combinations to enhance activity; (iv) Fungal mechanisms of resistance and the known causes of resistance emergence. As a result of this study we are able to track the fungal phylogenetics (and relationship) responsible for leather biodeterioration enabling a guiding strategy for fungal biocide application. Moreover, understanding of the mechanisms of action and interaction between molecules can determines the extent of the biocides inhibitory effect in different fungal species. Fungicide effect could vary, and such information corroborates with the idea that even in the same species the interaction of the different molecules may vary, possibly due to variation in cytochrome protein. For example, the most accepted mechanism of action of azoles is the inhibition of synthesis of or direct interaction with ergosterol (present in all fungi). Considering that the target is always the same, a question arise, how do the distinct azoles present different activities upon fungal strains? As result of this study we show that structural differences will influence the higher or lower interaction of the azole functional group and consequently the activity. The appropriated knowledge of the mechanisms by which microbial cells might develop resistance, highlights the need for an improved understanding of the reasons for their emergence and greater attention to methods that can be used to prevent and control them. In this sense, a successful combination of biocide molecules enhances a synergetic effect, avoiding fungal mechanisms of resistance and reduces dosage of each compound, being effective against a variety of fungi.
Take-Away:
Transfer of knowledge from the author of the fundermentals of bicides and fungicides used within the leather industry and similar industries, their application methods and how to use in combination for
maximum effect with minimum environmental impact.

Full textAbstract:
Scholars often need to search for matching, high-profile sci-entific events to publish their research results. Information about topical focus and quality of events is not made suÿciently explicit in the existing communication channels where events are announced. Therefore, schol-ars have to spend a lot of time on reading and assessing calls for papers but might still not find the right event. Additionally, events might be overlooked because of the large number of events announced every day. We introduce OpenResearch, a crowd sourcing platform that supports researchers in collecting, organizing, sharing and disseminating informa-tion about scientific events in a structured way. It enables quality-related queries over a multidisciplinary collection of events according to a broad range of criteria such as acceptance rate, sustainability of event series, and reputation of people and organizations. Events are represented in di˙erent views using map extensions, calendar and time-line visualiz-ations. We have systematically evaluated the timeliness, usability and performance of OpenResearch.

Full textAbstract:
Many parallel applications from scientific computing use MPI collective communication operations to collect or distribute data. Since the execution times of these communication operations increase with the number of participating processors, scalability problems might occur. In this article, we show for different MPI implementations how the execution time of collective communication operations can be significantly improved by a restructuring based on orthogonal processor structures with two or more levels. As platform, we consider a dual Xeon cluster, a Beowulf cluster and a Cray T3E with different MPI implementations. We show that the execution time of operations like MPI Bcast or MPI Allgather can be reduced by 40% and 70% on the dual Xeon cluster and the Beowulf cluster. But also on a Cray T3E a significant improvement can be obtained by a careful selection of the processor groups. We demonstrate that the optimized communication operations can be used to reduce the execution time of data parallel implementations of complex application programs without any other change of the computation and communication structure. Furthermore, we investigate how the execution time of orthogonal realization can be modeled using runtime functions. In particular, we consider the modeling of two-phase realizations of communication operations. We present runtime functions for the modeling and verify that these runtime functions can predict the execution time both for communication operations in isolation and in the context of application programs.

In der österreichischen Bibliothekenlandschaft waren bis vor einiger Zeit Klassifikationen kaum ein Thema, wenn doch dann für die Freihandaufstellung, wobei auch hier die sog. Haussystematiken bei weitem in der Überzahl waren und es auch weiterhin sind.
Erst in den letzten Jahren ist, verbunden mit dem Thema der Suchmaschinentechnologie, auch das Thema Klassifikationen wieder etwas in den Vordergrund gerückt, wobei in Österreich bisher vor allem die Regensburger Verbundklassifikation (RVK) und die Basisklassifikation (BK) angewendet werden, und auch das Interesse an der DDC wächst. Aber auch das Thema Aufstellung stellt sich für viele Bibliotheken in diesem Kontext erneut in dem Sinn, dass – im Zuge von Baumaßnahmen, aber teilweise auch aus grundsätzlichen Erwägungen – auch größere Bibliotheken ein Abgehen von vorhandenen Haussystematiken in Erwägung ziehen.

This thesis addresses key issues of scientific realism in the philosophy of biology and chemistry through investigation of an underexplored research domain: olfaction theory, or the science of smell. It also provides the first systematic overview of the development of olfactory practices and research into the molecular basis of odours across the 19th and 20th century. Historical and contemporary explanations and modelling techniques for understanding the material basis of odours are analysed with a specific focus on the entrenchment of technological process, research tradition and the definitions of materiality for understanding scientific advancement. The thesis seeks to make sense of the explanatory and problem solving strategies, different ways of reasoning and the construction of facts by drawing attention to the role and application of scientific representations in olfactory practices. Scientific representations such as models, classifications, maps, diagrams, lists etc. serve a variety of purposes that range from the stipulation of relevant properties and correlations of the research materials and the systematic formation of research questions, to the design of experiments that explore or test particular hypotheses. By examining a variety of modelling strategies in olfactory research, I elaborate on how I understand the relation between representations and the world and why this relation requires a pluralist perspective on scientific models, methods and practices. Through this work I will show how a plurality of representations does not pose a problem for realism about scientific entities and their theoretical contexts but, on the contrary, that this plurality serves as the most reliable grounding for a realistic interpretation of scientific representations of the world and the entities it contains. The thesis concludes that scientific judgement has to be understood through its disciplinary trajectory, and that scientific pluralism is a direct consequence of the historicity of scientific development.

Full textAbstract:
The understanding and treatment of challenging behaviors in individuals with Autism Spectrum Disorder is paramount to enabling the success of behavioral therapy; an essential step in this process being the labeling of challenging behaviors demonstrated in therapy sessions. These manifestations differ across individuals and within individuals over time and thus, the appropriate classification of a challenging behavior when considering purely qualitative factors can be unclear. In this thesis we seek to add quantitative depth to this otherwise qualitative task of challenging behavior classification. We do so through the application of natural language processing techniques to behavioral descriptions extracted from the CARD Skills dataset. Specifically, we construct 3 sets of 50-dimensional document embeddings to represent the 1,917 recorded instances of challenging behaviors demonstrated in Applied Behavior Analysis therapy. These embeddings are learned through three processes: a TF-IDF weighted sum of Word2Vec embeddings, Doc2Vec embeddings which use hierarchical softmax as an output layer, and Doc2Vec which optimizes the original Doc2Vec architecture through Negative Sampling. Once created, these embeddings are initially used as input to a Support Vector Machine classifier to demonstrate the success of binary classification within this problem set. This preliminary exploration achieves promising classification accuracies ranging from 78.2-100% and establishes the separability of challenging behaviors given their neural embeddings. We next construct a multi-class classification model via a Gaussian Process Classifier fitted with Laplace approximation. This classification model, trained on an 80/20 stratified split of the seven most frequently occurring behaviors in the dataset, produces an accuracy of 82.7%. Through this exploration we demonstrate that the semantic queues derived from the language of challenging behavior descriptions, modeled using natural language processing techniques, can be successfully leveraged in classification architectures. This study represents the first of its kind, providing a proof of concept for the application of machine learning to the observations of challenging behaviors demonstrated in ASD with the ultimate goal of improving the efficacy of the behavioral treatments which intrinsically rely on the accurate identification of these behaviors.

Full textAbstract:
A fundamental challenge is to understand nonequilibrium statistical mechanics starting from microscopic chaos in the equations of motion of a many-particle system. In this thesis we summarize recent theoretical advances along these lines. We focus on two different approaches to nonequilibrium transport: One considers Hamiltonian dynamical systems under nonequilibrium boundary conditions, another one suggests a non-Hamiltonian approach to nonequilibrium situations created by external electric fields and by temperature or velocity gradients. A surprising result related to the former approach is that in simple low-dimensional periodic models the deterministic transport coefficients are typically fractal functions of control parameters. These fractal transport coefficients yield the first central theme of this thesis. We exemplify this phenomenon by deterministic diffusion in a simple chaotic map. We then construct an arsenal of analytical and numerical methods for computing further transport coefficients such as electrical conductivities andchemical reaction rates. These methods are applied to hierarchies of chaotic dynamical systems that are successively getting more complex, starting from abstract one-dimensional maps generalizing a simple random walk on the line up to particle billiards that should be directly accessible in experiments. In all cases, the resulting transport coefficients turn out to be either strictly fractal, or at least to be profoundly irregular. The impact of random perturbations on these quantities is also investigated. We furthermore provide some access roads towards a physical understanding of these fractalities. The second central theme is formed by a critical assessment of the non-Hamiltonian approach to nonequilibrium transport. Here we consider situations where the nonequilibrium constraints pump energy into a system, hence there must be some thermal reservoir that prevents the system from heating up. For this purpose a deterministic and time-reversible modeling of thermal reservoirs was proposed in form of Gaussian and Nose-Hoover thermostats. This approach yielded simple relations between fundamental quantities of nonequilibrium statistical mechanics and of dynamical systems theory. Our goal is to critically assesses the universality of these results. As a vehicle of demonstration we employ the driven periodic Lorentz gas, a toy model for the classical dynamics of an electron in a metal under application of an electric field. Applying different types of thermal reservoirs to this system we compare the resulting nonequilibrium steady states with each other. Along the same lines we discuss an interacting many-particle system under shear and heat. Finally, we outline an unexpected relationship between deterministic thermostats and active Brownian particles modeling biophysical cell motility.

Full textAbstract:
Direct Volume Rendering (DVR) is a visualization technique that has proved to be a very powerful tool in many scientific visualization applications. Diagnostic medical imaging is one domain where DVR could provide clear benefits in terms of unprecedented possibilities for analysis of complex cases and highly efficient work flow for certain routine examinations. The full potential of DVR in the clinical environment has not been reached, however, primarily due to limitations in conventional DVR methods and tools. This thesis presents methods addressing four major challenges for DVR in clinical use. The foundation of all methods is to incorporate the domain knowledge of the medical professional in the technical solutions. The first challenge is the very large data sets routinely produced in medical imaging today. To this end a multiresolution DVR pipeline is proposed, which dynamically prioritizes data according to the actual impact in the rendered image to be reviewed. Using this prioritization the system can reduce the data requirements throughout the pipeline and provide high performance and visual quality in any environment. Another problem addressed is how to achieve simple yet powerful interactive tissue classification in DVR. The methods presented define additional attributes that effectively captures readily available medical knowledge. The task of tissue detection is also important to solve in order to improve efficiency and consistency of diagnostic image review. Histogram-based techniques that exploit spatial relations in the data to achieve accurate and robust tissue detection are presented in this thesis. The final challenge is uncertainty visualization, which is very pertinent in clinical work for patient safety reasons. An animation method has been developed that automatically conveys feasible alternative renderings. The basis of this method is a probabilistic interpretation of the visualization parameters. Several clinically relevant evaluations of the developed techniques have been performed demonstrating their usefulness. Although there is a clear focus on DVR and medical imaging, most of the methods provide similar benefits also for other visualization techniques and application domains.

Zeng, Chunqiu. "Large Scale Data Mining for IT Service Management." FIU Digital Commons, 2016. http://digitalcommons.fiu.edu/etd/3051.
Full textAbstract:
More than ever, businesses heavily rely on IT service delivery to meet their current and frequently changing business requirements. Optimizing the quality of service delivery improves customer satisfaction and continues to be a critical driver for business growth. The routine maintenance procedure plays a key function in IT service management, which typically involves problem detection, determination and resolution for the service infrastructure.
Many IT Service Providers adopt partial automation for incident diagnosis and resolution where the operation of the system administrators and automation operation are intertwined. Often the system administrators' roles are limited to helping triage tickets to the processing teams for problem resolving. The processing teams are responsible to perform a complex root cause analysis, providing the system statistics, event and ticket data. A large scale of system statistics, event and ticket data aggravate the burden of problem diagnosis on both the system administrators and the processing teams during routine maintenance procedures.
Alleviating human efforts involved in IT service management dictates intelligent and efficient solutions to maximize the automation of routine maintenance procedures. Three research directions are identified and considered to be helpful for IT service management optimization: (1) Automatically determine problem categories according to the symptom description in a ticket; (2) Intelligently discover interesting temporal patterns from system events; (3) Instantly identify temporal dependencies among system performance statistics data. Provided with ticket, event, and system performance statistics data, the three directions can be effectively addressed with a data-driven solution. The quality of IT service delivery can be improved in an efficient and effective way.
The dissertation addresses the research topics outlined above. Concretely, we design and develop data-driven solutions to help system administrators better manage the system and alleviate the human efforts involved in IT Service management, including (1) a knowledge guided hierarchical multi-label classification method for IT problem category determination based on both the symptom description in a ticket and the domain knowledge from the system administrators; (2) an efficient expectation maximization approach for temporal event pattern discovery based on a parametric model; (3) an online inference on time-varying temporal dependency discovery from large-scale time series data.

Este trabalho apresenta uma pesquisa exploratória usando o algoritmo Naive Bayes com capacidade para classificar documentos no Mendeley usando até cinco classes de saída, definidas com base na quantidade de leitores dos documentos. Usando uma série de atributos que foram encontrados durante a coleta de dados, é realizada a classificação para tentar identificar padrões nos atributos, a fim de reconhecer lógicas sociais dos cientistas, que envolve tanto o comportamento quanto sua dinâmica nas redes sociais científicas. Para fins de concretização deste trabalho, foi aplicada uma Revisão Sistemática de Literatura, a fim de buscar o estado da arte de pesquisas que envolvam o uso de Reconhecimento de Padrões em Redes Sociais Científicas, além da aplicação de um método que envolve o uso de algoritmos desenvolvidos para o tratamento automático de todos os dados coletados no Mendeley.
This work is an exploratory research using the Naive Bayes algorithm with the ability to classify documents in Mendeley using the output classes, based on the amount of reading of the documents. Using a series of data that was found during a data collection, a classification is given to check the patterns in the attributes, an end to recognize the social logics of the scientists, that involve both the behavior and its dynamics in scientific social networks. For the purpose of this work, a literature systematic review was applied, with emphasis on the use of methods that involve the use of social networking concepts, as well as the application of a method for the use of algorithms. Created for automatic processing of all data collected at Mendeley.

Full textAbstract:
Many prominent scientists have pointed out that philosophy is of no benefit to science. Stephen Hawking asserts: Philosophy is dead!
Sciences use conceptions like natural laws, matter, nature, theories, etc. But science is also confronted with questions such as: "What is a natural law?" "What is nature?" "What is matter?" and "What is a scientific theory?" These (metatheoretical) questions exceed the sphere of competence of science – they are items of the philosophy of science. Philosophy of science is a metatheory of science. The Philosophy of science overlaps epistemology, ontology, and metaphysics by exploring whether scientific results are true, or whether entities like quarks or electrons really exist. More detailed investigations bring various questions into consideration such as: "How do we define the boundaries between different scientific disciplines?" "Is there a relation between the beauty and the truth of a scientific theory?" and "How do we distinguish between science and pseudoscience?" Additionally, the philosophy of science is concerned with ethical problems of modern technology, with the methodological questions, with the reconstruction of the structure and the development of scientific theories, and with revealing of any indoctrination of science.
The optimistic conclusion of this paper is: Philosophy is still alive – but the philosopher has to participate in round-table discussions with scientists. We just want philosophers talking to scientists!

Full textAbstract:
Classifications are useful and efficient. We group things into kinds to facilitate the acquisition and transmission of important, often tacit, information about a particular entity qua member of some kind. Whilst it is universally acknowledged that classifications are useful, some scientific classifications (e.g. chemical elements) are held to higher epistemic standards than folk classifications (e.g. bugs). Scientific classifications in terms of 'natural kinds' are considered to be more reliable and successful because they are highly projectible and support law-like and inductive generalisations. What counts as a natural kind is, however, controversial: according to essentialists (e.g. Putnam, Kripke, Ellis) natural kinds are mind-independent and possess essential characteristics; according to promiscuous realists (e.g. Dupre ) there are 'countless legitimate, objectively grounded ways of classifying objects in the world'; and according to scientific realists (e.g. Boyd, Psillos) natural kinds are grounded in the 'causal structure of the world'. More specifically, realism about kinds can be understood as a commitment to the existence of natural divisions (kinds) in the world that we come to know as a result of mature scientific investigation into the nature of such kinds. Realism about natural kinds is supported and articulated in terms of three main arguments, metaphysical, semantical, and epistemological. In the first part of my thesis I offer a sustained and systematic investigation of these three main arguments, with their respective promises and prospects for the viability of realism about kinds and I find them wanting, whilst in the second part of the thesis I pursue an unexplored line of inquiry regarding natural kinds and propose a mild realism about natural kinds via the ontology of real patterns.

Full textAbstract:
Natural surfaces are usually associated with feature graphs, such as the cortical surface with anatomical atlas structure. Such a feature graph subdivides the whole surface into meaningful sub-regions. Existing brain mapping and registration methods did not integrate anatomical atlas structures. As a result, with existing brain mappings, it is difficult to visualize and compare the atlas structures. And also existing brain registration methods can not guarantee the best possible alignment of the cortical regions which can help computing more accurate shape similarity metrics for neurodegenerative disease analysis, e.g., Alzheimer’s disease (AD) classification. Also, not much attention has been paid to tackle surface parameterization and registration with graph constraints in a rigorous way which have many applications in graphics, e.g., surface and image morphing.
This dissertation explores structural mappings for shape analysis of surfaces using the feature graphs as constraints. (1) First, we propose structural brain mapping which maps the brain cortical surface onto a planar convex domain using Tutte embedding of a novel atlas graph and harmonic map with atlas graph constraints to facilitate visualization and comparison between the atlas structures. (2) Next, we propose a novel brain registration technique based on an intrinsic atlas-constrained harmonic map which provides the best possible alignment of the cortical regions. (3) After that, the proposed brain registration technique has been applied to compute shape similarity metrics for AD classification. (4) Finally, we propose techniques to compute intrinsic graph-constrained parameterization and registration for general genus-0 surfaces which have been used in surface and image morphing applications.

Full textAbstract:
Warum sind Reisekunden der DB AG spezielle Kunden, deren Loyalität vergleichsweise wenig belastbar und besonders leicht zu verletzen ist? Was unterminiert ihre Leidenschaft für das Bahnfahren? Warum ist selbst für den Quasimonopolisten DB AG die Förderung einer uneingeschränkten Loyalität seiner Reisekunden relevant? Was charakterisiert die Bindung des Loyalitätstypus alter Art? Und was kennzeichnet die Entwicklung und spezifische Funktionsweise der Bindung des Loyalitätstypus neuer Art?
Mit diesen Fragen greift die Autorin das Schnittstellenthema ‚Kundenloyalität in Dienstleistungsbeziehungen‘ auf, das viele Disziplinen bewegt, jedoch bislang in erster Linie quantitativ und aus Marketingsicht beforscht wurde. Carolyn Koch-Falkenberg fragt danach, wann und warum sich Kunden emotional an ein Unternehmen binden und diesem loyal sind, in welcher Form ihre Loyalität zu Tage tritt, was diese konterkariert und welche Folgen die Art ihrer Loyalitätsform nach sich zieht.
Im Mittelpunkt steht damit eine spezifische Form der Bindungsorientierung, welche die Autorin explorativ mittels qualitativer Methoden konsequent aus der Subjektperspektive der Kunden am Beispiel der Dienstleistungsbeziehung zwischen Reisekunden und dem Unternehmen DB AG sozialwissenschaftlich untersucht.Why are travel customers of DB AG special customers with a comparatively less resilient loyalty which is particularly easy to be violated? What undermines their passion for going by train? Why is even the promotion of the unlimited loyalty of travel customers relevant to the quasimonopolist DB AG? What characterizes the attachment of the old fashioned loyalty type? And what characterizes the development and specific functioning of the binding of the ‚new‘ loyalty type? The author seizes the interdisciplinary topic of the interface theme 'customer loyalty in service relationships', which ocupy many science disciplines, but has so far been primarily researched quantitatively from a marketing perspective. Carolyn Koch-Falkenberg asks when and why clients are emotionally attached to their loyality for a company, how their loyalty is revealed, how it counteracts and illustrates the consequences of their natural loyalty form. The focus is on a specific form of attachment orientation. The author is using socially and scientifically qualitative methods in order to research consistently the subject perspective of the customer at the example of the service relationship between travel customers and the company DB AG.
