description: Interbedded contourites, turbidites and pelagites are commonplace in many deep-water slope environments. However, the distinction between these different facies remains a source of controversy. This detailed study of calcareous contourites and associated deep-marine facies from an Eocene–Miocene sedimentary succession on Cyprus clearly documents the diagnostic value of microfacies in this debate. In particular, the variability of archetypical bi-gradational contourite sequences and their internal subdivision (bedding, layering and lamination) are explored. Contourites can be distinguished from turbidites, pelagites and hemipelagites by means of carbonate microfacies in combination with bed-scale characteristics. Particle composition provides valuable information on sediment provenance. Depositional texture, determined by the ratio between carbonate mud and bioclasts, is crucial for identifying bi-gradational sequences in both muddy and sandy contourites, and normally-graded sequences in turbidite beds. Equally important are the type and preservation of traction structures, as well as the temporality and impact of bioturbation. Shell fragmentation under conditions of increased hydrodynamic agitation (textural inversion) is recognized as a carbonate-specific feature of bioclastic sandy contourites.
D-brane anomaly inflow revisited

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Axial and gravitational anomaly of field theories, when embedded in string theory, must be accompanied by canceling inflow. We give a self-contained overview for various world-volume theories, and clarify the role of smeared magnetic sources in I-brane/D-brane cases. The proper anomaly descent of the source, as demanded by regularity of RR field strengths H's, turns out to be an essential ingredient. We show how this allows correct inflow to be generated for all such theories, including self-dual cases, and also that the mechanism is now insensitive to the choice between the two related but inequivalent forms of D-brane Chern-Simons couplings. In particular, SO(6)_R axial anomaly of d=4 maximal SYM is canceled by the inflow onto D3-branes via the standard minimal coupling to C_4. We also propose how, for the anomaly cancelation, the four types of Orientifold planes should be coupled to the spacetime curvatures, of which conflicting claims existed previously.

Mass flux characteristics in solid 4He for T> 100 mK: Evidence for Bosonic Luttinger Liquid behavior
Creators: name: Vekhov, Ye.

description: At pressure $\sim$ 25.7 bar the flux, $F$, carried by solid \4he for $T >$ 100 mK depends on the net chemical potential difference between two reservoirs in series with the solid, $Δμ$, and obeys $F \sim (Δμ)^b$, where $b \approx 0.3$ is independent of temperature. At fixed $Δμ$ the temperature dependence of the flux, $F$, can be adequately represented by $F \sim - \ln(T/τ)$, $τ\approx 0.6$ K, for $0.1 \leq T \leq 0.5$ K. A single function $F = F_0(Δμ)^b\ln(T/τ)$ fits all of the available data sets in the range 25.6 - 25.8 bar reasonably well. We suggest that the mass flux in solid \4he for $T > 100$ mK may have a Luttinger liquid-like behavior in this bosonic system.

description: We study the four-body exclusive semileptonic baryonic $\bar B$ decays of $B^-\to p\bar p \ell^- \barν_{\ell}$ ($\ell=e,μ,τ$) in the standard model. We find that their decay branching ratios are about $(1.0, 1.0,0.5)\times 10^{-4}$, respectively. In particular, the electron mode is close to the corresponding CLEO's upper limit of $5.2\times 10^{-3}$, while all results are about one or two orders of magnitude larger than the previous estimated values for the inclusive modes of $\bar B\to {\bf B\bar B'}\ell \bar ν$. Clearly, both B-factories of Belle and BaBar should be able to observe these exclusive four-body modes.

description: We use distant Blue Horizontal Branch stars with Galactocentric distances 16 < r/kpc < 48 as kinematic tracers of the Milky Way dark halo. We model the tracer density as an oblate, power-law embedded within a spherical power-law potential. Using a distribution function method, we estimate the overall power-law potential and the velocity anisotropy of the halo tracers. We measure the slope of the potential to be gamma ~ 0.4 and the overall mass within 50 kpc is ~ 4 x 10^11 M_sol. The tracer velocity anisotropy is radially biased with beta ~ 0.5, which is in good agreement with local solar neighbourhood studies. Our results provide an accurate outer circular velocity profile for the Milky Way and suggest a relatively high concentration dark matter halo (c_vir ~ 20).

description: We present a novel approach to quality control during the processing of astronomical data. Quality control in the Astro-WISE Information System is integral to all aspects of data handing and provides transparent access to quality estimators for all stages of data reduction from the raw image to the final catalog. The implementation of quality control mechanisms relies on the core features in this Astro-WISE Environment (AWE): an object-oriented framework, full data lineage, and both forward and backward chaining. Quality control information can be accessed via the command-line awe-prompt and the web-based Quality-WISE service. The quality control system is described and qualified using archive data from the 8-CCD Wide Field Imager (WFI) instrument (http://www.eso.org/lasilla/instruments/wfi/) on the 2.2-m MPG/ESO telescope at La Silla and (pre-)survey data from the 32-CCD OmegaCAM instrument (http://www.astro-wise.org/~omegacam/) on the VST telescope at Paranal.

description: To achieve a certain visual quality or a sufficient surface outlook in the injection-molded component, an increased mold surface temperature is needed. In order to achieve this, injections molds can be dynamically tempered, by integrating a discrete heating and cooling process inside the mold halves. The heating and cooling of mold halves become more efficient when the cooling and heating effect occurs closer to the tool surface. Due to the additive manufacturing layer by layer of the tools, channels that carry cold or hot liquids can be manufactured close to the contour directly under the mold surface. In this case, laser powder bed fusion (L-PBF) as an additive manufacturing process has special advantages, in particular, so-called hybrid tools can be manufactured, e.g. tool inserts or complex structures with conformal temperature control can be manufactured additively on a simple machined base plate. Thermal simulations focusing optimization of the injection molding process by the use of a dynamic conformal cooling is shown in this study. Furthermore, a dynamic conformal tempered tool was developed with contour-near temperature control and produced additively with maraging steel by means of L-PBF and tested it experimentally.
The urban governance of climate change : a comparative socio-institutional analysis of transformative urban responses to climate change in Durban (South Africa) and Portland (OR, USA)
Creators: name: Aylett, Alexander C.E.
Publisher: name: University of British Columbia
Year: 2011

description: This dissertation investigates the socio-political dynamics of urban attempts to address climate change in a systemic, rather than project-based or piecemeal, fashion. It focuses on the actions of both municipal and civil-society actors, as well as their interactions through formal and informal processes of participation and collaboration. It contributes to the larger re-theorization of the urban scale as a potentially powerful locus for action on climate change that has arisen as international climate negotiations have faltered (Betsill 2001, Bulkeley and Betsill 2003, 2005, Burch 2009, Kousky & Schneider 2003). Focusing on two exceptional cities at the forefront of urban climate policy, this dissertation looks more closely at the difficult work involved in relocalizing meaningful climate action to the urban scale. Based on comparative qualitative research conducted in Durban (KZN, South Africa) and Portland (OR, USA) this dissertation investigates how cities can make a transition from a limited project-based approach to more integrated and transformative responses to climate change. As I will show, systemic responses to climate change require, above all, a transition from climate government to climate governance (Bridge & Perreault 2009, Hajer 2003). Far-reaching transformations of urban systems lie beyond what any one actor can impose or direct. Effective climate responses therefore depend on the diffusion of policy making, management, and implementation along networks that draw together government actors traditionally isolated by bureaucratic silos, as well as private companies, civil-society groups, and citizens. Contributing to a clearer understanding of networks of urban climate governance, this dissertation focuses on two key facets of the creation of networks of urban climate governance. First it examines the institutional dynamics that take place within municipal bureaucracies, as policy leaders build support for integrated and ambitious climate policies. This contributes to the broad literature on organizational behaviour and change (Veblen 1914, Merton 1940, March and Olsen 1989, Schoenberger 1997, Latour 1987). Second, contributing to the literature on public participation and governance (Arnstein 1969, Taylor & Fransman 2004, Holmes & Scoones 2000, Silver et al. 2010, de Souza 2006 ) it analyses how civil-society actors shape and even lead ambitious urban responses to climate change.

description: Let $G$ be a finite connected simple graph with a vertex set $V(G)$ and an edge set $E(G)$. A total signed dominating function of $G$ is a function $f: V(G)\cup E(G)\rightarrow \{-1, 1\}$, such that $\sum_{y\in N_T[x]}f(y) \geq 1$ for all $x\in V(G) \cup E(G)$. The total signed domination number of $G$ is the　minimum weight of a total signed dominating function on $G$. In this　paper, we prove lower and upper bounds on the total signed　domination number of the Cartesian product of two paths, $P_m\Box P_n$.

description: Current-driven domain wall (DW) motion is investigated in Pt/Co/GdOx nanostrips with perpendicular magnetic anisotropy. Measurements of the propagation field and the energy barrier for thermally activated DW motion reveal a large current-induced torque equivalent to an out-of-plane magnetic field of ~60 Oe per 10^11 A/m^2. This same field-to-current scaling is shown to hold in both the slow thermally activated and fast near-flow regimes of DW motion. The current-induced torque decreases with 4 Å of Pt decorating the Co/GdOx interface and vanishes entirely with Pt replacing GdOx, suggesting that the Co/GdOx interface contributes directly to highly efficient current-driven DW motion.

description: The notions of ball hull and ball intersection of nite sets, important in Banach space theory, are extended from normed planes to generalized normed planes, i.e., to (asymmetric) convex distance functions which are also called gauges. In this more general setting we derive various new results about these notions and their relations to each other. Further on, we extend the known 2-center problem and a modified version of it from the Euclidean situation to norms and gauges or, in other words, from Euclidean circles to arbitrary closed convex curves. We derive algorithmical results on the construction of ball hulls and ball intersections, and computational approaches to the 2-center problem with constrained circles and, in case of strictly convex norms and gauges, for the fixed 2-center problem are also given.

Hydrodynamic outcomes of planet scattering in transitional discs

description: A significant fraction of unstable multiple planet systems likely scatter during the transitional disc phase as gas damping becomes ineffectual. Using an ensemble of FARGO hydrodynamic simulations and MERCURY n-body integrations, we directly follow planet-disc and planet-planet interactions through the clearing phase and on through 50 Myr of dynamical evolution. Disc clearing occurs via X-ray driven photoevaporation. The hydrodynamic evolution of individual scattering systems is complex, and involves phases in which massive planets orbit within eccentric gaps, or accrete directly from the disc without a gap. Comparing the results to a gas-free model, we find that the n-body dynamics and hydrodynamics of scattering into one- and two-planet final states are almost identical. The eccentricity distributions in these channels are almost unaltered by the presence of gas. The hydrodynamic simulations, however, also form low eccentricity three-planet systems in long-term stable configurations, and the admixture of these systems results in modestly lower eccentricities in hydrodynamic as opposed to gas-free simulations. The incidence of these three-planet systems is likely a function of the initial conditions; different planet setups (number or spacing) may change the character of this result. We analyze the properties of surviving multiple planet systems, and show that only a small fraction (a few percent) enter mean-motion resonances after scattering, while a larger fraction form stable resonant chains and avoid scattering entirely. Our results remain consistent with the hypothesis that exoplanet eccentricity results from scattering, though the detailed agreement between observations and gas-free simulation results is likely coincidental. We discuss the prospects for testing scattering models by observing planets or non-axisymmetric gas structure in transitional discs.

Strengthening scholarly publishing in Africa : assessing the potential of online systems
Creators: name: Esseh, Samuel Kwaku Smith
Publisher: name: University of British Columbia
Year: 2011

description: This study investigated current publishing practices among scholarly journals in Africa, while exploring the potential contribution of online publishing systems to aid those practices. This study examined how current systems, largely involving traditional publishing methods, offer Africans limited opportunities and incremental gains in taking advantage of faster and wider dissemination of digital systems for scholarly communication. Issues about authorship, readership, editorial and peer review, as well as the level of science resources in African academic libraries, were studied. Using a well-articulated, mixed-mode research design, this study has assembled data from 286 key actors – journal editors, potential journal editors, librarians, IT administrators, faculty and postgraduate students – from sub -Saharan Africa during a 12-month period in 2007–09. Drawing on this data set, this study documents and analyzes the unparalleled availability of journals and other information resources made available to the African research community through digital technologies and publisher policies, as well as current constraints in ICT infrastructure, training, and support inhibiting the utilization of these same technologies in advancing African scholarly publishing efforts. This study establishes the high level of energy and excitement among journals editors, librarians, and IT administrators about the compelling new possibilities offered by new digital technologies. Drawing on what has been learned in this study, recommendations are made for tapping into the full potential of these technologies in strengthening research capacity, improving the quality of research, reducing Africa’s isolation from the global scholarly community, and ultimately narrowing the information divide.

description: We present BOCoSy, a tool for bounded symbolic output-feedback controller synthesis. BOCoSy synthesizes symbolic output-feedback controllers which interact with a given plant via a pre-defined finite symbolic interface. BOCoSy solves this problem by a new lazy abstraction-refinement technique which starts with a very coarse abstraction of the external trace semantics of the given plant and iteratively removes non-admissible behavior from this abstract model until a controller is found. BOCoSy steers the search for controllers towards small and concise state space representations by utilizing ideas from bounded synthesis. As a result, BOCoSy returns small and explainable controllers that are still powerful enough to solve the given synthesis problem. We show that BOCoSy is able to synthesize small, human readable symbolic controllers quickly on a set of benchmarks.

description: For an integer $k \ge 1$, a (distance) $k$-dominating set of a connected graph $G$ is a set $S$ of vertices of $G$ such that every vertex of $V(G) \setminus S$ is at distance at most~$k$ from some vertex of $S$. The $k$-domination number, $\gamma_k(G)$, of $G$ is the minimum cardinality of a $k$-dominating set of $G$. In this paper, we establish lower bounds on the $k$-domination number of a graph in terms of its diameter, radius, and girth. We prove that for connected graphs $G$ and $H$, $\gamma_k(G \times H) \ge \gamma_k(G) + \gamma_k(H) -1$, where $G \times H$ denotes the direct product of $G$ and $H$.

description: The increasing interest in the bio-impedance analysis in various fields has increased the demand for portable and low-cost impedance analyzers that can be used in the field. Simplifying the hardware is crucial to maintaining low-cost and portability, but this is not an easy task due to the need for accurate phase and magnitude measurements. This thesis proposes a new measurement technique that replaces the need to measure the phase by using a software algorithm to extract the phase from the magnitude information. The algorithm which is based on a modified Kramers-Kronig transforms was implemented and tested first using MATLAB, where error and noise analysis on the algorithm were done. Furthermore, the algorithm was written using a python code, and a full Bio-impedance measurement system was proposed to be used for fruit quality control which is receiving increasing attention as an important application of bio-impedance measurements, for being a non-invasive technique. The Final design which was implemented on a printed circuit board (PCB), had a final cost of around $95 CAD and drew a maximum current of around 88mA which satisfies the requirement of a low-cost and low-power device respectively. The device was then tested with passive components and several fruit samples to show that it can effectively monitor fruit samples impedance in the range 100 Ohm-280 kOhm, and a frequency range 1 Hz-10 MHz which is higher than any other work in the literature. The proposed portable bio-impedance analyzers were then used to study the ageing effect of some strawberries samples on their bio-impedance, and the results showed that the device could be used in such an application.

description: Andrews [Generalized Frobenius partitions. Memoirs of the American Math. Soc., 301:1{44, 1984] defined the two classes of generalized F-partitions: F-partitions and k-color F-partitions. For many q-series and Rogers-Ramanujan type identities, the bijections are established between F-partitions and (n + t)-color partitions. Recently (n + t)-color partitions have been extended to split (n+t)-color partitions by Agarwal and Sood [Split (n+t)-color partitions and Gordon-McIntosh eight order mock theta functions. Electron. J. Comb., 21(2):#P2.46, 2014]. The purpose of this paper is to study the k-color F-partitions as a combinatorial tool. The paper includes combinatorial proofs and bijections between split (n + t)-color partitions and 2-color F-partitions for some generalized q-series. Our results further give rise to innate three-way combinatorial identities in conjunction with some Rogers-Ramanujan type identities for some particular cases.

description: Recent experimental and theoretical approaches have attempted to quantify the physical organization (compaction and geometry) of the bacterial chromosome with its complement of proteins (the nucleoid). The genomic DNA exists in a complex and dynamic protein-rich state, which is highly organised at various length scales. This has implications on modulating (when not enabling) the core biological processes of replication, transcription, segregation. We overview the progress in this area, driven in the last few years by new scientific ideas and new interdisciplinary experimental techniques, ranging from high space- and time-resolution microscopy to high-throughput genomics employing sequencing to map different aspects of the nucleoid-related interactome. The aim of this review is to present the wide spectrum of experimental and theoretical findings coherently, from a physics viewpoint. We also discuss some attempts of interpretation that unify different results, highlighting the role that statistical and soft condensed matter physics, and in particular classic and more modern tools from the theory of polymers, plays in describing this system of fundamental biological importance, and pointing to possible directions for future investigation.

description: Can dogs communicate through verbal language? Indeed, dogs possess numerous means to convey their sentiments, emotions, desires, and intentions, hence the response should be affirmative.  Dogs, like humans, engage in both verbal and nonverbal forms of communication to interact with each other and their human owners. It is crucial to comprehend the communication of your pets to raise them effectively and ensure that they receive their entitlements, companionship, and wellbeing. Simultaneously, certain dogs may experience multiple behavioral abnormalities throughout their lifespan, which can frequently become a threat. This article aims to investigate the communication methods of dogs, focusing particularly on the interpretation of their tail wagging and ear locations. Dogs lack the ability to verbally communicate, yet they possess the capacity to successfully convey messages through nonverbal means. Here are some significant elements of their nonverbal communication.

description: A novel idea is proposed for integrating digital watermarking capabilities into com­plementary metal-oxide semiconductor (CMOS) image sensors. The background of watermarking and previous hardware implementation is given and a simple digital watermarking scheme, ideal for implementation in a CMOS image sensor, is outlined. The watermarking algorithm was analyzed in terms of the effect on image quality, the statistics for successful watermark detection, and its susceptibility to attack. It was found that image quality could be high if less than three watermark bits were added to an image. A trend was also discovered that if the inequality 28 -/'MN 2 2048 is satisfied, where M and N are the dimensions of the image, in pixels, and 8 is the number of bits used for the watermark values, successful detection statistics will be obtained. It was also demonstrated that removing a watermark placed with this particular algorithm is relatively easy using low-pass filters; however, extracting the watermark from a watermarked image for insertion into an unauthorized image was accomplished and represents a greater threat. A device prototype was designed and fabricated and the results are discussed. The design of key components is highlighted in the context of the larger system. The operation of the chip in terms of signals and timing is given. Successful fabrication turned out to be an elusive goal and the difficulties encountered provide valuable information to the next phase of the project, recently submitted for fabrication. Finally, the noise data show conclusively that fixed pattern noise (FP ) is a useful source for key generation. It allows for the unique identification of sensors through the key generation process; however, small changes in the input data can affect the key, if the length of the key is large enough. Keys should be stored in non-volatile memory on the image sensor in order to speed up the image capture process. In summary, a complete system from sensor to key generation to embedding and detection of digital watermarks has been created, and can help provide a much needed boost to image veracity in target applications.

description: In the present paper we use anti-hook differences of Agarwal and Andrews as an elementary tool to provide new partition theoretic meanings to two generalized basic series in terms of ordinary partitions satisfying certain anti-hook difference conditions. Five particular cases are also discussed. These particular cases yield new partition theoretic versions of G\"{o}llnitz-Gordon identities and G\"{o}llnitz identity. Five $q$-identities of Rogers and three $q$-identities of Slater are further explored. These results extend the work of Goyal and Agarwal, Agarwal and Rana and Sareen and Rana.

Strings at Finite Temperature: Wilson Lines, Free Energies, and the Thermal Landscape

description: According to the standard prescriptions, zero-temperature string theories can be extended to finite temperature by compactifying their time directions on a so-called "thermal circle" and implementing certain orbifold twists. However, the existence of a topologically non-trivial thermal circle leaves open the possibility that a gauge flux can pierce this circle --- i.e., that a non-trivial Wilson line (or equivalently a non-zero chemical potential) might be involved in the finite-temperature extension. In this paper, we concentrate on the zero-temperature heterotic and Type I strings in ten dimensions, and survey the possible Wilson lines which might be introduced in their finite-temperature extensions. We find a rich structure of possible thermal string theories, some of which even have non-traditional Hagedorn temperatures, and we demonstrate that these new thermal string theories can be interpreted as extrema of a continuous thermal free-energy "landscape". Our analysis also uncovers a unique finite-temperature extension of the heterotic SO(32) and $E_8\times E_8$ strings which involves a non-trivial Wilson line, but which --- like the traditional finite-temperature extension without Wilson lines --- is metastable in this thermal landscape.

Intrinsic anomalous Hall effect in nickel: An GGA+U study

description: The electronic structure and intrinsic anomalous Hall conductivity of nickel have been calculated based on the generalized gradient approximation (GGA) plus on-site Coulomb interaction (GGA+U) scheme. It is found that the intrinsic anomalous Hall conductivity ($σ_{xy}^H$) obtained from the GGA+U calculations with $U = 1.9$ eV and $J=1.2$ eV, is in nearly perfect agreement with that measured recently at low temperatures while, in contrast, the $σ_{xy}^H$ from the GGA calculations is about 100% larger than the measured one. This indicates that, as for the other spin-orbit interaction (SOI)-induced phenomena in 3$d$ itinerant magnets such as the orbital magnetic magnetization and magnetocrystalline anisotropy, the on-site electron-electron correlation, though moderate only, should be taken into account properly in order to get the correct anomalous Hall conductivity. The intrinsic $σ_{xy}^H$ and the number of valence electrons ($N_e$) have also been calculated as a function of the Fermi energy ($E_F$). A sign change is predicted at $E_F = -0.38$ eV ($N_e = 9.57$), and this explain qualitatively why the theoretical and experimental $σ_{xy}^H$ values for Fe and Co are positive. It is also predicted that fcc Ni$_{(1-x)}$Co(Fe,Cu)$_x$ alloys with $x$ being small, would also have the negative $σ_{xy}^H$ with the magnitude being in the range of $500\sim 1400$ $Ω^{-1}$cm$^{-1}$. The most pronounced effect of including the on-site Coulomb interaction is that all the $d$-dominant bands are lowered in energy relative to the $E_F$ by about 0.3 eV, and consequently, the small minority spin X$_2$ hole pocket disappears. The presence of the small X$_2$ hole pocket in the GGA calculations is attributed to be responsible for the large discrepancy in the $σ_{xy}^H$ between theory and experiment.

Active learning by design: An undergraduate introductory public health course
Creators: name: Yeatts K.B.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Principles of active learning were used to design and implement an introductory public health course. Students were introduced to the breadth and practice of public health through team and individual-based activities.Team assignments covered topics in epidemiology, biostatistics, health behavior, nutrition, maternal and child health, environment, and health policy. Students developed an appreciation of the population perspective through an "experience" trip and related intervention project in a public health area of their choice. Students experienced several key critical component elements of a public health undergraduate major; they explored key public health domains, experience public health practice, and integrated concepts with their assignments. In this paper, course assignments, lessons learned, and student successes are described. Given the increased growth in the undergraduate public health major, these active learning assignments may be of interest to undergraduate public health programs at both liberal arts colleges and research universities.

description: While reactive synthesis and syntax-guided synthesis (SyGuS) have seen enormous progress in recent years, combining the two approaches has remained a challenge. In this work, we present the synthesis of reactive programs from Temporal Stream Logic modulo theories (TSL-MT), a framework that unites the two approaches to synthesize a single program. In our approach, reactive synthesis and SyGuS collaborate in the synthesis process, and generate executable code that implements both reactive and data-level properties. We present a tool, temos, that combines state-of-the-art methods in reactive synthesis and SyGuS to synthesize programs from TSL-MT specifications. We demonstrate the ap- plicability of our approach over a set of benchmarks, and present a deep case study on synthesizing a music keyboard synthesizer.
Many-electron dynamics triggered by massively parallel ionization

description: Massively parallel ionization of many atoms in a cluster or bio-molecule is identified as new phenomenon of light-matter interaction which becomes feasible through short and intense FEL pulses. Almost simultaneously emitted from the illuminated target the photo-electrons can have such a high density that they interact substantially even after photo-ionization. This interaction results in a characteristic electron spectrum which can be interpreted as convolution of a mean-field electron dynamics and binary electron-electron collisions. We demonstrate that this universal spectrum can be obtained analytically by summing synthetic two-body Coulomb collision events. Moreover, we propose an experiment with hydrogen clusters to observe massively parallel ionization.

Aping the substantive epistemic subject?: in search of epistemic equals in the genus pan
Creators: name: Fenton, Andrew Timothy
Publisher: name: University of Calgary
Year: 2007

description: Bibliography: p. 293-314
description: In this dissertation I examine and defend the claim that chimpanzees and bonobos are substantive epistemic subjects-where to be a substantive epistemic subject is to have the capacity to engage in activities of an epistemic nature governed by rules or standards adopted, or learnt, by the individual in question and held in common with her belief community. In Chapter One I introduce, and in Chapter Two defend, six conditions for being a substantive epistemic subject that do not beg the question as to which animal species qualify. In Chapters Three through Five I set out to show that chimpanzees and bonobos meet all of these conditions, necessitating a discussion of various ethological studies of these great apes. As I show in Chapters Three and Four, there are compelling reasons for not only holding that chimpanzees and bonobos possess beliefs (or what I call Triple-I States) but that they engage in activities properly regarded as epistemic in nature. This constitutes a defence of the claim that chimpanzees and bonobos meet my first five conditions for being substantive epistemic subjects. With a defence, in Chapter Five, of the claim that chimpanzees and bonobos achieve a degree of epistemic success in their epistemic activities - which satisfies my final condition for being an epistemic subject - I provide the grounds needed to justify the claim that these nonhuman great apes are, in effect, our epistemic equals.

description: (English) In this lecture I discuss recent progress in the understanding of the chemical evolution of protoplanetary disks that resemble our Solar system during the first ten million years. At the verge of planet formation, strong variations of temperature, density, and radiation intensities in these disks lead to a layered chemical structure. In hot, dilute and heavily irradiated atmosphere only simple radicals, atoms, and atomic ions can survive, formed and destroyed by gas-phase processes. Beneath the atmosphere a partly UV-shielded, warm molecular layer is located, where high-energy radiation drives rich chemistry, both in the gas phase and on dust surfaces. In a cold, dense, dark disk midplane many molecules are frozen out, forming thick icy mantles where surface chemistry is active and where complex (organic) species are synthesized.
