A defence of extended cognitivism
Creators: name: Godwyn, Martin
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation defends extended cognitivism: a recently emerging view in the philosophy of mind and cognitive science that claims that an individual's cognitive processes or states sometimes extend beyond the boundaries of their brain or their skin to include states and processes in the world. I begin the defence of this thesis through a background discussion of several foundational issues in cognitive science: the general character of cognitive behaviour and cognitive processes, as well as the nature and role of representation as it is standardly taken to figure in cognition. I argue in favour of the widely held view that cognition is best characterised as involving information processing, and that carriers of information (i.e., representations) are ineliminable components of the most distinctively human and powerful forms of cognition. Against this background the dissertation argues in stages for successively stronger claims regarding the explanatory role of the external world in cognition. First to be defended is the claim that cognition is often embedded in one's environment. I develop this claim in terms of what I call 'parainformation': roughly, information that shapes how we tackle a cognitive task by enabling the extraction of task-relevant information. Proceeding then to the defence of extended cognitivism, I draw most significantly on the work of Andy Clark. In outline, and in general following Clark, it is argued that states and processes occurring beyond the skin of the cognitive agent sometimes play the same explanatory role as internal processes that unquestionably count as cognitive. I develop this claim in two versions of differing strength: firstly, in a general way without commitment to the representational character of extended cognition, and secondly in a specifically representational version with special attention to intentional explanation. Against each of these versions of extended cognitivism are ranged a number of criticisms and objections, many of which stem from the work of Fred Adams and Ken Aizawa. The dissertation examines these objections and rejects each of them in turn.

description: In Europe, private forest owners have a key role in sustainable forests management, maintaining the productivity of forests and satisfy society's needs for wood. Private forests in Poland are 18.4% of the total forests area. They are characterized by high diversify, due to the size of the forest complexes as well as area and also distribution within the country. The existing legal solutions in the field of private forests are not sufficient. Seems to be necessary to introduce the possibility to organize forest owners so they can jointly lead forest management. In that context, it should also update the current regulation or introduce new legislation. Increasingly evident is the need to increase the effectiveness of management in private forests in Poland and to strengthening their environmental role. / Synopsis. W Europie właściciele lasów prywatnych mają kluczową rolę w prowadzeniu zrównoważonej gospodarki leśnej, utrzymaniu produkcyjności lasów oraz zaspokojeniu potrzeb społeczeństwa na drewno. Lasy prywatne w Polsce to 18,4% powierzchni lasów. Charakteryzują się one dużym zróżnicowaniem, zarówno ze względu na wielkość kompleksów leśnych, jak i powierzchnię należącą do jednego właściciela, a także rozmieszczenie w obrębie kraju. Obecnie funkcjonujące rozwiązania prawne w zakresie lasów prywatnych są niewystraczające. Niezbędne zdaje się być wprowadzenie możliwości organizowania się właścicieli lasów tak, aby mogli wspólnie prowadzić gospodarkę leśną. W tym, też kontekście należy zaktualizować obecnie obowiązujące przepisy lub wprowadzić nowe regulacje prawne. W coraz większym stopniu widoczna jest potrzeba zwiększenia efektywności gospodarowania w lasach prywatnych w Polsce oraz wzmocnienia ich roli środowiskotwórczej.

description: We present the first computation of the Cosmic Microwave Background (CMB) polarisation power spectrum from galaxy clusters and filaments using hydrodynamical simulations of large scale structure. We give the $E$ and $B$ mode power spectra of the CMB quadrupole induced polarisation between $\ell \sim 560$ and 20000. We find that the contribution from warm ionised gas in filamentary structures dominates the polarised signal from galaxy clusters by more than one order of magnitude on large scales (below $\ell \sim 1000$) and by a factor of about two on small scales ($\ell \gsim 10000$). We study the dependence of the power spectra with $σ_8$. Assuming the power spectra vary like $σ_8^n$ we find $n=3.2-4.0$ for filaments and $n=3.5-4.6$ for clusters.

description: The aim of analysis was attempt assessment two groups farms with field crops depending on balance of emission warming gases from soil. First group contained farms with negative balance of emission warming gases from soil while second group of farms contained farms with positive balance of emission warming gases from soil. Comparative analysis concerned their production potential and structure, economic effectiveness and intensification of investment. In this purpose used empirical data from farms with field crops which collect accountancy data for Polish FADN. It has been found that farms with negative balance of emission warming gases achieve better economic situation and larger intensification of investment than other farms. / Synopsis. Celem badań była ocena dwóch grup gospodarstw specjalizujących się w produkcji roślinnej w zależności od salda emisji gazów cieplarnianych z gleby. Pierwszą grupę gospodarstw stanowiły gospodarstwa z ujemnym saldem emisji gazów cieplarnianych z gleby, natomiast drugą grupę gospodarstwa z saldem dodatnim. Następnie analizie porównawczej poddano ich potencjał produkcyjny, strukturę produkcji, efektywność ekonomiczną oraz nasilenie inwestycyjne. Do realizacji tak rozumianego celu wykorzystano dane empiryczne z gospodarstw specjalizujących się w produkcji roślinnej, które prowadziły nieprzerwanie rachunkowość rolną dla potrzeb Polskiego FADN w latach 2005-2010. Stwierdzono, że gospodarstwa z ujemnym saldem emisji gazów cieplarnianych z gleby w porównaniu z gospodarstwami z saldem dodatnim były w lepszej sytuacji ekonomicznej i charakteryzowały się większym nasileniem inwestycyjnym.

description: We construct a new Evans function for quasi-periodic solutions to the linearisation of the sine-Gordon equation about a periodic travelling wave. This Evans function is written in terms of fundamental solutions to a Hill's equation. Applying Evans-Krein function theory to our Evans function, we provide a new method for computing the Krein signatures of simple characteristic values of the linearised sine-Gordon equation. By varying the Floquet exponent parametrising the quasi-periodic solutions, we compute the linearised spectra of periodic travelling wave solutions of the sine-Gordon equation and and track dynamical Hamiltonian-Hopf bifurcations via the Krein signature. Finally, we show that our new Evans function can be readily applied to the general case of the nonlinear Klein-Gordon equation with a non-periodic potential.

title: An exploration of young children's number sense on entry to primary school in Ireland
Creators: name: Dunphy, Elizabeth
Publisher: name: The Open University
Year: 2006

description: The importance of number sense lies in its relationship with mathematical proficiency. Consequently, number sense is increasingly emphasised in curriculum documentation related to mathematics. The Primary School Curriculum: Mathematics (Government of Ireland, 1999b) is no exception. It implicitly stresses the importance of number sense and draws teachers' attention to a range of key aspects. My study is premised on the belief that young children's number sense is developed as a result of their everyday experiences with numbers, and these experiences form the basis on which further development of number sense, both in and out of school, takes place. Two questions are investigated: What number sense do young children demonstrate on entry to school?; What is the congruence between young children's number sense and the curriculum for the first year of primary school? The first question is explored through individual experience-based flexible, focused interviews with fourteen children (eight boys and six girls) early in their first term at primary school. The age-range of the children was 4 years, I month to 5 years, I month. The second question is addressed by means of an analysis of relevant curriculum documentation and then linking that analysis to the data analysis. A framework for exploring number sense in young children was developed. This included four aspects: Pleasure and interest in number; Understandings of the purposes of number; Quantitative thinking; and Awareness/Understanding of numerals. Affective issues emerged as centrally important in the development of children's number sense. Counting purposes were most transparent for children, with generic, communicative and label purposes also identified by them. There were striking differences in the ways in which girls and boys constructed their metacognitive framework in relation to number. Children's responses to quantification tasks provided interesting insights into how children perceived such tasks. The process of estimation appears to be challenging for many four-year-old children. A number of areas of omission were identified in the teacher guidelines that accompany the curriculum documents. Implications were drawn with respect to how aspects of children's number sense, for example estimation, are developed at school. Implications for teacher education are also discussed.

description: A method is presented for the registration and correlation of intrinsic property maps of materials, including data from nanoindentation hardness, Electron Back-Scattered Diffraction (EBSD), Electron Micro-Probe Analysis (EPMA). This highly spatially resolved method allows for the study of micron-scale microstructural features, and has the capability to rapidly extract correlations between multiple features of interest from datasets containing thousands of datapoints. Two case studies are presented in commercially pure (CP) titanium: in the first instance, the effect of crystal anisotropy on measured hardness and, in the second instance, the effect of an oxygen diffusion layer on hardness. The independently collected property maps are registered us-ing affine geometric transformations and are interpolated to allow for direct correlation. The results show strong agreement with trends observed in the literature, as well as providing a large dataset to facilitate future statistical analysis of microstructure-dependent mechanisms.

description: Developing competency in the broad area of bioinformatics is challenging globally, owing to the breadth of the field and the diversity of its audiences for education and training. Course design can be facilitated by the use of a competency framework – a set of competency requirements that define the knowledge, skills and attitudes needed by individuals in (or aspiring to be in) a particular profession or role. These competency requirements can help to define curricula as they can inform both the content and level to which competency needs to bedeveloped. The International Society for Computational Biology (ISCB) developed a list of bioinformatics competencies in 2014, and these have undergone several rounds of improvement. In consultation with a broad bioinformatics training community, these have now been further refined and extended to include knowledge skills and attitudes, and mappings to previous and other existing competency frameworks. Here we present version 3 of the ISCB competency framework. We describe how it was developed and how to access it, as well as providing some examples of how it has been used. The framework is openly accessible at https://competency.ebi.ac.uk/framework/iscb/3.0/competencies.
On the Mass Distribution of the Intra-Cluster Light in Galaxy Groups and Clusters

description: We take advantage of a semi-analytic model with a state-of-art implementation of the formation of the intra-cluster light (ICL) to study the mass distribution of the ICL in galaxy groups and clusters, at different redshifts. We assume the ICL to follow a NFW profile with a different concentration, linked to that of the dark matter by the relation $c_{ICL}=γc_{DM}$, where the parameter $γ$ is set to reproduce the observed relation between the stellar mass in the brightest cluster galaxy (BCG) and ICL in the innermost 100 kpc and the halo mass ($M^*_{100}-M_{500}$), at $z=0$. The model is then tested against several theoretical and observational results, from the present time to $z\sim1.5$. Our analysis shows that the fraction of stellar mass in the BCG and ICL within the innermost 100 kpc is an increasing function of redshift, parameter $γ$, and a decreasing function of the halo mass. The value of $γ$ required to match the observed $M^*_{100}-M_{500}$ is $γ=3$ at $z=0$, but there are hints that it might be a function of redshift and halo mass. This result indicates that the distribution of the ICL is more concentrated than the dark matter one, but less concentrated than previously found by other studies. We suggest that a modified version of the NFW is a good description of the distribution of the diffuse light in groups and clusters, which makes the ICL a reliable tracer of the dark matter, in good agreement with recent observational findings.

description: We compute the exact density of states and 2-point function of the $\mathcal{N} =2$ super-symmetric SYK model in the large $N$ double-scaled limit, by using combinatorial tools that relate the moments of the distribution to sums over oriented chord diagrams. In particular we show how SUSY is realized on the (highly degenerate) Hilbert space of chords. We further calculate analytically the number of ground states of the model in each charge sector at finite $N$, and compare it to the results from the double-scaled limit. Our results reduce to the super-Schwarzian action in the low energy short interaction length limit. They imply that the conformal ansatz of the 2-point function is inconsistent due to the large number of ground states, and we show how to add this contribution. We also discuss the relation of the model to $SL_q(2|1)$. For completeness we present an overview of the $\mathcal{N}=1$ super-symmetric SYK model in the large $N$ double-scaled limit.

description: As fuzz testing has passed its 30th anniversary, and in the face of the incredible progress in fuzz testing techniques and tools, the question arises if the classic, basic fuzz technique is still useful and applicable? In that tradition, we have updated the basic fuzz tools and testing scripts and applied them to a large collection of Unix utilities on Linux, FreeBSD, and MacOS. As before, our failure criteria was whether the program crashed or hung. We found that 9 crash or hang out of 74 utilities on Linux, 15 out of 78 utilities on FreeBSD, and 12 out of 76 utilities on MacOS. A total of 24 different utilities failed across the three platforms. We note that these failure rates are somewhat higher than our in previous 1995, 2000, and 2006 studies of the reliability of command line utilities. In the basic fuzz tradition, we debugged each failed utility and categorized the causes the failures. Classic categories of failures, such as pointer and array errors and not checking return codes, were still broadly present in the current results. In addition, we found a couple of new categories of failures appearing. We present examples of these failures to illustrate the programming practices that allowed them to happen. As a side note, we tested the limited number of utilities available in a modern programming language (Rust) and found them to be of no better reliability than the standard ones.

description: Introduction Positron emission tomography (PET) with two tracers is a novel medical imaging technique which has advantages such as shortening the duration of scans, however PET cannot explicitly distinguish between two tracers as both signals stem from 511 keV photon pairs. The aims of this thesis were to (1) determine the behaviour of [18]F - Fluoroethylcholine (FEC) within the prostate in prostate cancer patients for the time interval of 48 minutes to 71 minutes post injection for patients with prostate cancer and (2) to analyse the feasibility of dual tracer PET using FEC and [68]Ga labelled prostate-specific membrane antigen (PSMA). Methods Two retrospective studies based on PET data were analysed in prostate cancer patients. The first study analysed the stability of FEC by comparing the activity of FEC at two time points (48 and 71 minutes) for 6 patients. The second study involved a static PET acquisition of FEC followed by an injection and dynamic acquisition of PSMA. Signal separation was done by background subtraction, with the assumption (supported by the results from the first study) that FEC remained stable, to obtain values for the estimated PSMA activity. Kinetic modeling was performed to compare obtained parameters between the estimated PSMA activities and one patient who was only administered PSMA. Results The percent change in quantitative values for the whole prostate varied less than 10 % for 4 of the 6 patients in the first study. No significant wash out or wash in was observed. In the second study, the irreversible two-tissue compartment model was the best fit kinetic model for PSMA. The influx parameter Ki for all patients had the same order of magnitude for each patient with the value ranging from 0.01 to 0.08 1/min. Conclusions The findings in literature and results from the analysis of the choline stability study suggest that FEC remains trapped within cells, however, a full dynamic PET acquisition of FEC activity is advised. Estimated PSMA activity showed similar values for kinetic parameters with the PSMA only patient, however, issues representing true quantification were discussed as there exists a trade off between the benefits of acquired data with multiple tracer PET and quantification.

description: Nonuniform neutron-rich matter present in both core-collapse supernovae and neutron-star crusts is described in terms of a semiclassical model that reproduces nuclear-matter properties and includes long-range Coulomb interactions. The neutron-neutron correlation function and the corresponding static structure factor are calculated from molecular dynamics simulations involving 40,000 to 100,000 nucleons. The static structure factor describes coherent neutrino scattering which is expected to dominate the neutrino opacity. At low momentum transfers the static structure factor is found to be small because of ion screening. In contrast, at intermediate momentum transfers the static structure factor displays a large peak due to coherent scattering from all the neutrons in a cluster. This peak moves to higher momentum transfers and decreases in amplitude as the density increases. A large static structure factor at zero momentum transfer, indicative of large density fluctuations during a first-order phase transition, may increase the neutrino opacity. However, no evidence of such an increase has been found. Therefore, it is unlikely that the system undergoes a simple first-order phase transition. It is found that corrections to the commonly used single heavy nucleus approximation first appear at a density of the order of $10^{13}$ g/cm$^3$ and increase rapidly with increasing density. Thus, neutrino opacities are overestimated in the single heavy nucleus approximation relative to the complete molecular dynamics simulations.

title: Gender, age and technology: a feminist analysis of older women learning the Internet
Creators: name: Ashcroft, Lorna Stephanie
Publisher: name: The Open University
Year: 2005

description: This report explores the perceptions of retired women who have chosen to learn to use the Internet from a professional tutor. This qualitative study interprets these perceptions using a grounded approach within the perspective of feminist epistemology. The focus on retired women informs theory on a group of lifelong learners who have not been widely studied within either educational research or feminism. Where there has been feminist research into gender and technology the imperatives have related to the public domains of compulsory education or workplace training. Using three research questions, this research enquires into what motivates older women learners to challenge the stereotype of the young, male Internet user, whether they find the course that they have chosen to be suitable for their requirements and what, if any, difference they perceive the skill will make to their lives. Data were collected by semi-structured interviews with students and tutors and supplemented by background information from college staff and fliers. My own research diary supported a reflexive approach and biographical details of the respondents added context to the central enquiries. Several themes emerged from the data which related the concepts of age and gender to this particular aspect of technological education. This diverse group of middle class women revealed varied motivations for using the Internet, reflecting a common determination to avoid the social exclusion which they felt would be the fate of technologically illiterate elderly people in the twenty-first century. Their experience of learning foregrounds lack of self confidence, learning computer terminology and physical health issues as problems of age as well as gender. It was difficult to establish impact in 'a short-term study, but the criterion of a quality of life model was useful as a tool for analysis of the personal and social effects of being able to use the Internet. This research has shown that retired women are willing and able to challenge age and gender stereotypes in order to use contemporary information and communication technology if they see it as relevant to their lives. Overall, the most significant conclusion was that this method of communication, while still unfamiliar, has been recognized by older women as a means to maintain their gendered identities into old age and has implications for the empowerment of other previously silent groups through the medium of the Internet.
Electrical band flattening, valley flux, and superconductivity in twisted trilayer graphene

description: Twisted graphene multilayers have demonstrated to yield a versatile playground to engineer controllable electronic states. Here, by combining first-principles calculations and low-energy models, we demonstrate that twisted graphene trilayers provide a tunable system where van Hove singularities can be controlled electrically. In particular, it is shown that besides the band flattening, bulk valley currents appear, which can be quenched by local chemical dopants. We finally show that in the presence of electronic interactions, a non-uniform superfluid density emerges, whose non-uniformity gives rise to spectroscopic signatures in dispersive higher energy bands. Our results put forward twisted trilayers as a tunable van der Waals heterostructure displaying electrically controllable flat bands and bulk valley currents.

title: The perceived role(s) of year heads in a secondary school, in the implementation of the positive behavioural policy
Creators: name: Gordon, Mary
Publisher: name: The Open University
Year: 2006

description: The school is a small Catholic secondary (550+) in an inner-city area, implementing a positive behavioural policy. The research is a case study of year heads and aspects of their perceived role(s). It was undertaken in line with the drive for school improvement and effectiveness, which focuses on learning. Interviews were carried out within and outside pastoral middle and senior management, meetings were observed, and class tutors were surveyed using a questionnaire to ascertain their views of their line managers ' roles.

 The sample included twelve class tutors, five year heads and several middle and senior managers, plus observations of many meetings and examination of some documents. Detailed semi-structured interviews were conducted and a substantial questionnaire accessed class tutors' expectations of the year head role with regard to the policy. Data on how roles were sent and how people knew what to do emerged.

 Following an initial study, research instruments were further developed and tested. Data were coded and assessed qualitatively. They were thematically analysed using some grounded theory methods. This case study will show year heads working ceaselessly to fulfil the tasks associated with their roles, in the context of the implementation of the positive behavioural policy, within the setting examined, but it will reveal their own feelings of a shortfall between the enacted role and the subjective role, limiting their perceived effectiveness within role.

 A key issue which appeared was that roles and effectiveness within the context of Pastoral' middle leadership were found to be dependent upon trust and autonomy. Themes such as time shortage, training needs, role tensions and overload emerged from the data. Another theme uncovered was many participants' disregard of the pastoral/academic divide, preferring a more holistic role for year heads.

 Conclusions tentatively suggesting ideas of distributed leadership and communities of practice, as possible solutions to the problems of such middle leader role fulfilment, were drawn.

description: Coherent molecular optics is performed using two-photon Bragg scattering. Molecules were produced by sweeping an atomic Bose-Einstein condensate through a Feshbach resonance. The spectral width of the molecular Bragg resonance corresponded to an instantaneous temperature of 20 nK, indicating that atomic coherence was transferred directly to the molecules. An autocorrelating interference technique was used to observe the quadratic spatial dependence of the phase of an expanding molecular cloud. Finally, atoms initially prepared in two momentum states were observed to cross-pair with one another, forming molecules in a third momentum state. This process is analogous to sum-frequency generation in optics.

description: Access to Higher Education (HE) courses provided in Further Education (FE) Colleges are an established part of the Government's drive to widen participation in HE. Like all FE courses, Access courses must justify their continuation by demonstrating their success. This dissertation reports on a case study of Access courses provided by one department in a general FE College in the North of England, and examines whether or not they are successful.

 A review of relevant literature suggests that a key issue is by what criteria Access courses are to be judged. Policy makers, quality assurance agencies, HE Institutions, college managers, course managers, course tutors and students all have perspectives on 'success', which overlap and often are in tension.

 The research explores these perspectives, drawing on both qualitative and quantitative data, using an ethnographical framework. Semi-structured interviews with students, staff and others complement management data from internal and external sources. A grounded theory approach was used to generate themes of interest for analysis. The participant observer status of the researcher provided additional insight, as well as raising issues.

The research suggests that in the discussion of success of these Access courses there is a tension between two dominant discourses, here labelled the managerialist discourse and the humanist discourse. Tension is found to result from the difference between criteria for the success of courses and criteria for the success of individuals. The research demonstrates the significance of students' perspectives on 'success'.

Criteria for success that took into account more qualitative information could be developed but would require a shift in policy. Issues are raised in the dissertation concerning the reliability of available data and suggestions are made as to potential future development and further research.

Search for heavy resonances decaying into a photon and a hadronically decaying Higgs boson in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector

description: This Letter presents a search for the production of new heavy resonances decaying into a Higgs boson and a photon using proton-proton collision data at $\sqrt{s}=13$ TeV collected by the ATLAS detector at the LHC. The data correspond to an integrated luminosity of 139 fb$^{-1}$. The analysis is performed by reconstructing hadronically decaying Higgs boson $(H\to b\bar{b})$ candidates as single large-radius jets. A novel algorithm using information about the jet constituents in the center-of-mass frame of the jet is implemented to identify the two $b$-quarks in the single jet. No significant excess of events is observed above the expected background. Upper limits are set on the production cross-section times branching fraction for narrow spin-1 resonances decaying into a Higgs boson and a photon in the resonance mass range from 0.7 to 4 TeV, cross-sections times branching fraction are excluded between 11.6 fb and 0.11 fb at a 95% confidence level.

description: We investigate bipartite entanglement in spin-1/2 systems on a generic lattice. For states that are an equal superposition of elements of a group $G$ of spin flips acting on the fully polarized state $\ket{0}^{\otimes n}$, we find that the von Neumann entropy depends only on the boundary between the two subsystems $A$ and $B$. These states are stabilized by the group $G$. A physical realization of such states is given by the ground state manifold of the Kitaev's model on a Riemann surface of genus $\mathfrak{g}$. For a square lattice, we find that the entropy of entanglement is bounded from above and below by functions linear in the perimeter of the subsystem $A$ and is equal to the perimeter (up to an additive constant) when $A$ is convex. The entropy of entanglement is shown to be related to the topological order of this model. Finally, we find that some of the ground states are absolutely entangled, i.e., no partition has zero entanglement. We also provide several examples for the square lattice.

Asymptotically fast group operations on Jacobians of general curves

description: Let $C$ be a curve of genus $g$ over a field $k$. We describe probabilistic algorithms for addition and inversion of the classes of rational divisors in the Jacobian of $C$. After a precomputation, which is done only once for the curve $C$, the algorithms use only linear algebra in vector spaces of dimension at most $O(g \log g)$, and so take $O(g^{3 + ε})$ field operations in $k$, using Gaussian elimination. Using fast algorithms for the linear algebra, one can improve this time to $O(g^{2.376})$. This represents a significant improvement over the previous record of $O(g^4)$ field operations (also after a precomputation) for general curves of genus $g$.

Resonant dispersive wave emission in hollow capillary fibres filled with pressure gradients

description: Resonant dispersive wave (RDW) emission in gas-filled hollow waveguides is a powerful technique for the generation of bright few-femtosecond laser pulses from the vacuum ultraviolet to the near infrared. Here we investigate deep-ultraviolet RDW emission in a hollow capillary fibre filled with a longitudinal gas pressure gradient. We obtain broadly similar emission to the constant-pressure case by applying a surprisingly simple scaling rule for the gas pressure and study the energy-dependent dispersive-wave spectrum in detail using simulations. We further find that in addition to enabling dispersion-free delivery to experimental targets, a decreasing gradient also reduces the pulse stretching within the waveguide itself, and that transform-limited pulses with 3 fs duration can be generated by using short waveguides. Our results illuminate the fundamental dynamics underlying this frequency conversion technique and will aid in fully exploiting it for applications in ultrafast science and beyond.

Mm-wave HCO+, HCN and CO absorption toward NGC1052

description: We used the Plateau de Bure Interferometer to observe $λ$3mm J=1-0 absorption lines of \hcop, HCN and CO toward the core of the nearby elliptical, megamaser-host galaxy NGC1052. The lines are relatively weak, with peak optical depths 0.03 for \hcop and HCN and 0.1 for CO. Nonetheless the inferred column density of molecular gas 2N(\HH) $\simeq 5\times10^{21}~\pcc$ is consistent with the degree of reddening inferred toward the nucleus from observations of the Balmer series of hydrogen. Mm-wave absorption line profiles are somewhat broader than those of H I and OH, perhaps because lower free-free opacity at mm-wavelengths exposes higher-velocity material nearer the nucleus. Overall, the OH/\hcop ratio in NGC1052 is as expected from the strong relationship established in local diffuse clouds but the optical depth ratio varies strongly over the line profiles. Similar variations are also seen toward Cen A, which has very different line ratios among H I, OH and \hcop for very nearly the same amount of OH absorption.

Application and re-use of information and knowledge in managing risks of infrastructure projects

description: The management of economic risks is critical for the success of major infrastructure projects. As with other management challenges, the tasks associated with risk management rely heavily on knowledge and experience, and also involve the use of a diverse and sizeable set of information. Thus, computer-based methodologies that can allow the application and re-use of information and knowledge have the potential to be particularly useful to an organization in managing risks. Described in this thesis are the results of an effort to develop such a methodology. The methodology represents the risks and the context to which they apply by considering five dimensions or views. The five dimensions are the Risks, the Physical components of the project, the Processes required to procure and operate it, the Organizational entities involved, and the Environment in which it is being procured and operated. The methodology facilitates the creation of enterprise-level ontologies or libraries for each of these views. The libraries which can be augmented over time are made up of components relevant to a particular view which are modeled in a project-neutral format. Information and knowledge that is relevant to supporting project risk management is modeled within the components. In analysing the risks of an individual project, the methodology facilitates the development of project-specific models for each of the five dimensions for that particular project making use of the content of the libraries. The relationship between the context and risks is modeled through a driver-issue relationship and refined using the notion of spatial and temporal gateways. The methodology also allows the user to leverage the representations to derive insights such as the distribution of risks among spatial location and among project participants, and the evolution of risks as project conditions change. It is anticipated that the functionality provided for re-using information and knowledge and for leveraging available information will assist an organization in identifying a more complete set of risks, in providing more refined input to economic models used in decision making, and in deciding on appropriate risk assignments, thus bringing an organization closer to achieving success on the projects they undertake.
