description: Properties of asymmetric nuclear matter are derived from various many-body approaches. This includes phenomenological ones like the Skyrme Hartree-Fock and relativistic mean field approaches, which are adjusted to fit properties of nuclei, as well as more microscopic attempts like the Brueckner-Hartree-Fock approximation, a self-consistent Greens function method and the so-called $V_{lowk}$ approach, which are based on realistic nucleon-nucleon interactions which reproduce the nucleon-nucleon phase shifts. These microscopic approaches are supplemented by a density-dependent contact interaction to achieve the empirical saturation property of symmetric nuclear matter. The predictions of all these approaches are discussed for nuclear matter at high densities in $β$-equilibrium. Special attention is paid to behavior of the isovector component of the effective mass in neutron-rich matter.

description: Kernel methods have been studied extensively in recent years. We propose a three-dimensional (3-D) Epanechnikov Mixture Regression (EMR) based on our Epanechnikov Kernel (EK) and realize a complete framework for image coding. In our research, we deduce the covariance-matrix form of 3-D Epanechnikov kernels and their correlated statistics to obtain the Epanechnikov mixture models. To apply our theories to image coding, we propose the 3-D EMR which can better model an image in smaller blocks compared with the conventional Gaussian Mixture Regression (GMR). The regressions are all based on our improved Expectation-Maximization (EM) algorithm with mean square error optimization. Finally, we design an Adaptive Mode Selection (AMS) algorithm to realize the best model pattern combination for coding. Our recovered image has clear outlines and superior coding efficiency compared to JPEG below 0.25bpp. Our work realizes an unprecedented theory application by: (1) enriching the theory of Epanechnikov kernel,(2) improving the EM algorithm using MSE optimization, (3) exploiting the EMR and its application in image coding, and (4) AMS optimal modeling combined with Gaussian and Epanechnikov kernel.

description: This study uses an innovative measure, the Semantic Brand Score, to assess the interest of stakeholders in different company core values. Among others, we focus on corporate social responsibility (CSR) core value statements, and on the attention they receive from five categories of stakeholders (customers, company communication teams, employees, associations and media). Combining big data methods and tools of Social Network Analysis and Text Mining, we analyzed about 58,000 Italian tweets and found that different stakeholders have different prevailing interests. CSR gets much less attention than expected. Core values related to customers and employees are in the foreground.
Essays in structural heuristics

Subjects: SECS-P/04 Storia del pensiero economico

description: This dissertation introduces and develops a new method of rational reconstruction called structural heuristics. Structural heuristics takes assignment of structure to any given object of investigation as the starting point for its rational reconstruction. This means to look at any given object as a system of relations and of transformation laws for those relations. The operational content of this heuristics can be summarized as follows: when facing any given system the best way to approach it is to explicitly look for a possible structure of it. The utilization of structural heuristics allows structural awareness, which is considered a fundamental epistemic disposition, as well as a fundamental condition for the rational reconstruction of systems of knowledge.
In this dissertation, structural heuristics is applied to reconstructing the domain of economic knowledge. This is done by exploring four distinct areas of economic research: (i) economic axiomatics; (ii) realism in economics; (iii) production theory; (iv) economic psychology. The application of structural heuristics to these fields of economic inquiry shows the flexibility and potential of structural heuristics as epistemic tool for theoretical exploration and reconstruction.

description: The state-of-the-art deep learning-based object recognition YOLO algorithm and object tracking DeepSORT algorithm are combined to analyze digital images from fluid dynamic simulations of multi-core emulsions and soft flowing crystals and to track moving droplets within these complex flows. The YOLO network was trained to recognize the droplets with synthetically prepared data, thereby bypassing the labor-intensive data acquisition process. In both applications, the trained YOLO + DeepSORT procedure performs with high accuracy on the real data from the fluid simulations, with low error levels in the inferred trajectories of the droplets and independently computed ground truth. Moreover, using commonly used desktop GPUs, the developed application is capable of analyzing data at speeds that exceed the typical image acquisition rates of digital cameras (30 fps), opening the interesting prospect of realizing a low-cost and practical tool to study systems with many moving objects, mostly but not exclusively, biological ones. Besides its practical applications, the procedure presented here marks the first step towards the automatic extraction of effective equations of motion of many-body soft flowing systems.

The control of singing in varied thrushes
Creators: name: Whitney, Carl Linn
Publisher: name: University of British Columbia
Year: 2010

description: Male varied thrushes (Zoothera naevius) have repertoires of three to seven different songs. A typical song is a pure tone, about two seconds long and modulated in amplitude; it can be described quantitatively by its dominant frequency (Hz) and period of modulation. Reduced to these two dimensions, the songs within repertoires are more dissimilar to each other than would be expected if they were drawn at random from all the songs in the population. This pattern is consistent with a theory that explains the adaptive significance of song and song repertoires. According to the theory, song helps territorial males to repel other males and to attract and stimulate females, and repertoires enhance these effects by reducing the rate at which other birds habituate. This being so, it is to the advantage of males to have repertoires of dissimilar songs, since other birds will generalize less between the songs and will therefore habituate at a slower rate. The relationship between generalization and similarity of songs forms the basis of a theory of how singing is controlled by the brain of a varied thrush. The theory assumes that a control center feeds motivational impulses to units in charge of the different songs. When the motivational state of a unit reaches a threshold, the unit produces a song and then inhibits itself, dropping abruptly to a lower motivational state. At the same time, it inhibits each of the other units an amount that is directly proportional to the similarity of the songs produced by the two units. Some random variability in inhibition is not explained by this relationship. k simulation model based on this theory accounts for the following patterns found in sequences of songs produced by varied thrushes: 1) Once a song has been sung, it is not usually repeated immediately. 2) Songs are not sung with equal frequency. 3) The most common song in a repertoire is more likely than any other to be repeated immediately. 4) There is a negative correlation between the lengths of successive recurrence intervals (where a recurrence interval is defined as one plus the number of other songs between successive repetitions of a given song). 5) The two most dissimilar songs in a repertoire are more likely to be sung in succession than would be expected if they occurred independently of each other. 6) When several of the songs in a repertoire are dropped and replaced by others, the ones that remain occur in different relative frequencies. 7) Two very similar songs in a repertoire can occur with quite different frequencies. 8) Intervals between successive songs are variable but are usually at least several seconds long. 9) The average lengths of the intervals following different songs are positively correlated with the relative frequencies of the songs. 10) The absolute variability of the intervals between successive songs is positively correlated with the rate of singing. The theory can be elaborated to account for patterns of singing in other species.

description: Coronal upflows at the edges of active regions (AR), which are a possible source of slow solar wind, have been found to connect with dynamics in the transition region. To infer at what scale transition region dynamics connect to AR upflows, we investigate the statistical properties of the small-scale dynamics in the transition region underneath the upflows at the edge of AR NOAA 11934. With observations from the Interface Region Imaging Spectragraph (IRIS), we found that the Si IV 1403\,Å Doppler map consists of numerous blue-shifted and red-shifted patches mostly with sizes less than 1\,$Mm^2$. The blue-shifted structures in the transition region tend to be brighter than the red-shifted ones, but their nonthermal velocities have no significant difference. With the SWAMIS feature tracking procedure, in IRIS slit-jaw 1400\,Å images we found that dynamic bright dots with an average size of about 0.3\,$Mm^2$ and lifetimes mostly less than 200\,s spread all over the region. Most of the bright dots appear to be localised, without clear signature of propagation of plasma to a long distance on the projection plane. Surge-like motions with speeds about 15 km/s could be seen in some events at the boundaries of the upflow region, where the magnetic field appear to be inclined. We conclude that the transition region dynamics connecting to coronal upflows should occur in very fine scale, suggesting that the corresponding coronal upflows should also be highly-structured. It is also plausible that the transition region dynamics might just act as stimulation at the coronal base that then drives the upflows in the corona.

title: Economy and society in Dover 1509-1640
Creators: name: Dixon, Mary
Publisher: name: University of Kent
Year: 2021

description: This study examines the relationship between economy and society in Dover between 1509-1640. Dover's harbour, threatened by choking shingle, was twice improved by royal intervention, and in the first half of the seventeenth century, during periods of English neutrality, was used as an entrepot for the transhipment of international goods. Through the use of detail, the study attempts to demonstrate the process of urban life and government, and considers the economic, social and cultural consequence of the changes at the harbour. It examines the civic accounts closely, not only for fiscal and social, but also for cultural information, showing how successive corporations, while responding to economic fluctuations and instructions from central government, operated a moral economy. Other evidence is used to show how, in the new conditions of the seventeenth century, wealth accrued to individuals, some of them alien merchants and factors, increasingly from the distribution rather than the production of goods and also from the manipulation of capital. The population possibly tripled over the whole period, and it is suggested that the gap between rich and poor widened in the early seventeenth century. Social structures throughout the period are shown to have been based on occupational networks, extended kinship, status and mutual obligation, and often to have involved the extension and receipt of credit. Protestantism was readily embraced by the ruling group, who are shown to have become both more exclusive and more efficient over the period. From the beginning of the seventeenth century they began to finance civic rule with loans at interest. In spite of greater profits from the harbour, they were under pressure then from forced billeting, recurrent disease, and increasing numbers of transient poor, whom they treated punitively. At that time, too, the Crown made more demands upon them without offering any compensating concessions, so that by 1640 change seems to have been inevitable.
Non-Perturbative Contribution to the Thrust Distribution in $e^+ e^-$ Annihilation

description: We re-evaluate the non-perturbative contribution to the thrust distribution in $e^+e^-\to$ hadrons, in the light of the latest experimental data and the recent NNLO perturbative calculation of this quantity. By extending the calculation to NNLO+NLL accuracy, we perform the most detailed study to date of the effects of non-perturbative physics on this observable. In particular, we investigate how well a model based on a low-scale QCD effective coupling can account for such effects. We find that the difference between the improved perturbative distribution and the experimental data is consistent with a $1/Q$-dependent non-perturbative shift in the distribution, as predicted by the effective coupling model. Best fit values of $α_s(M_Z) = 0.1164^{+0.0028}_{-0.0026}$ and $α_0(2 GeV)=0.59+/-0.03$ are obtained with $χ^2/d.o.f.=1.09$. This is consistent with NLO+NLL results but the quality of fit is improved. The agreement in $α_0$ is non-trivial because a part of the 1/Q-dependent contribution (the infrared renormalon) is included in the NNLO perturbative correction.

description: A unified derivation of the off equilibrium fluctuation dissipation relations (FDR) is given for Ising and continous spins to arbitrary order, within the framework of Markovian stochastic dynamics. Knowledge of the FDR allows to develop zero field algorithms for the efficient numerical computation of the response functions. Two applications are presented. In the first one, the problem of probing for the existence of a growing cooperative length scale is considered in those cases, like in glassy systems, where the linear FDR is of no use. The effectiveness of an appropriate second order FDR is illustrated in the test case of the Edwards-Anderson spin glass in one and two dimensions. In the second one, the important problem of the definition of an off equilibrium effective temperature through the nonlinear FDR is considered. It is shown that, in the case of coarsening systems, the effective temperature derived from the second order FDR is consistent with the one obtained from the linear FDR.

description: We perform high-statistics Monte Carlo simulations of three-dimensional Ising spin-glass models on cubic lattices of size L: the +- J (Edwards-Anderson) Ising model for two values of the disorder parameter p, p=0.5 and p=0.7 (up to L=28 and L=20, respectively), and the bond-diluted bimodal model for bond-occupation probability p_b = 0.45 (up to L=16). The finite-size behavior of the quartic cumulants at the critical point allows us to check very accurately that these models belong to the same universality class. Moreover, it allows us to estimate the scaling-correction exponent ωrelated to the leading irrelevant operator: ω=1.0(1). Shorter Monte Carlo simulations of the bond-diluted bimodal models at p_b=0.7 and p_b=0.35 (up to L=10) and of the Ising spin-glass model with Gaussian bond distribution (up to L=8) also support the existence of a unique Ising spin-glass universality class. A careful finite-size analysis of the Monte Carlo data which takes into account the analytic and the nonanalytic corrections to scaling allows us to obtain precise and reliable estimates of the critical exponents νand η: we obtain ν=2.45(15) and η=-0.375(10).

Seasonal movements of black-tailed deer on northern Vancouver Island
Creators: name: Harestad, Alton Sidney
Publisher: name: University of British Columbia
Year: 2010

description: Columbian black-tailed deer (Qdocoileus hemionug cplumbianus Richardson) were radio-tagged in a deep snowfall region on northern Vancouver Island, British Columbia. These deer were monitored to determine seasonal movements and habitat use. Deer exhibited either resident or migratory movement patterns. Resident deer made seasonal shifts in their home range centres but their seasonal home ranges overlapped. In migratory deer, summer home ranges were separated from both spring and winter home ranges, although their spring and winter home ranges overlapped. Altitudinal migrations occurred by deer moving between high and low elevation habitats. Horizontal migrations occurred by deer moving between a small tributary valley and the main valley. Seasonal movements of black-tailed deer result from habitat selection by deer seasonally moving to more favourable habitats as determined by more available energy and nutrients, and lower risk of predation. The causal differences between vertical and horizontal migrations as well as seasonal shifts in home range centres can be resolved by a model of habitat selection based on these factors. The densities of available digestible dry matter in Amabilis Fir - Twisted Stalk, and Mountain Hemlock - Copperbush associations are comparable with those in the shrub and conifer serai stages. This abundance of deer food in high elevation habitats suggests that forest harvesting in high elevations will not affect deer populations, if their other habitat requirements are met. In areas where forested summer ranges already exist, low elevation logging of Sword Fern - Western Red Cedar, Deer Fern - Western Hemlock, and Western Hemlock - Plagiothecium associations will provide deer with sources of abundant food closer to their winter ranges than the high elevation summer ranges. Use of these food sources may result in only a redistribution and not an increase in the deer population. Logging of Amabilis Fir - Western Hemlock, Salal - Douglas-fir, and Salal - Western Hemlock associations may be detrimental to deer populations because of their need for these habitats during winter. Management policies emphasizing preservation of severe winter range could be detrimental to deer populations. Habitat management for black-tailed deer must include provision of mild winter range as well as severe winter range. Because mild winter range provides deer with greater amounts of available energy and nutrients, it may be as important to the over-winter survival of deer as is severe winter range. The mobility of black-tailed deer and their sensitivity to snow suggest that few deer would be trapped in high elevations by early snowfalls. Corridors joining high and low elevations appear unnecessary to facilitate deer migrations.
Collisions of paramagnetic molecules in magnetic fields: an analytic model based on Fraunhofer diffraction of matter waves

description: We investigate the effects of a magnetic field on the dynamics of rotationally inelastic collisions of open-shell molecules ($^2Σ$, $^3Σ$, and $^2Π$) with closed-shell atoms. Our treatment makes use of the Fraunhofer model of matter wave scattering and its recent extension to collisions in electric [M. Lemeshko and B. Friedrich, J. Chem. Phys. \textbf{129}, 024301 (2008)] and radiative fields [M. Lemeshko and B. Friedrich, Int. J. Mass. Spec. in press (2008)]. A magnetic field aligns the molecule in the space-fixed frame and thereby alters the effective shape of the diffraction target. This significantly affects the differential and integral scattering cross sections. We exemplify our treatment by evaluating the magnetic-field-dependent scattering characteristics of the He -- CaH ($X ^2Σ^+$), He -- O$_2$ ($X ^3Σ^-$) and He -- OH ($X ^2Π_Ω$) systems at thermal collision energies. Since the cross sections can be obtained for different orientations of the magnetic field with respect to the relative velocity vector, the model also offers predictions about the frontal-versus-lateral steric asymmetry of the collisions. The steric asymmetry is found to be almost negligible for the He -- OH system, weak for the He -- CaH collisions, and strong for the He -- O$_2$. While odd $ΔM$ transitions dominate the He -- OH $(J=3/2,f \to J', e/f)$ integral cross sections in a magnetic field parallel to the relative velocity vector, even $ΔM$ transitions prevail in the case of the He -- CaH ($X ^2Σ^+$) and He -- O$_2$ ($X ^3Σ^-$) collision systems. For the latter system, the magnetic field opens inelastic channels that are closed in the absence of the field. These involve the transitions $N=1, J=0 \to N', J' $ with $J'=N'$.

description: To calculate the conductivity of a material having full knowledge of its composition is a reasonably simple task. To do the same in reverse, i.e., to find information about the composition of a device from its conductivity response alone, is very challenging and even more so in the presence of disorder. An inversion methodology capable of decoding the information contained in the conductivity response of disordered structures has been recently proposed but despite claims of generality and robustness, the method has only been used with 2D systems possessing relatively simple electronic structures. Here we put these claims to the test and generalise the inversion method to the case of monolayer MoS$_2$, a material whose electronic structure is far more complex and elaborate. Starting from the spectral function that describes the DC conductivity of a disordered sample of a single layered MoS$_2$ containing a small concentration of randomly dispersed vacancies, we are able to invert the signal and find the exact composition of defects with an impressive degree of accuracy. Remarkably, equally accurate results are obtained with the optical conductivity. This is indicative of a methodology that is indeed suitable to extract composition information from different 2D materials, regardless of their electronic structure complexity. Calculated conductivity results were used as a proxy for their experimental counterpart and were obtained with an efficient quantum transport code (KITE) based on a real-space multi-orbital tight-binding model with parameters generated by density functional theory.

description: A recent focus of quantum spin liquid (QSL) studies is how disorder/randomness in a QSL candidate affects its true magnetic ground state. The ultimate question is whether the QSL survives disorder or the disorder leads to a "spin-liquid-like" state, such as the proposed random-singlet (RS) state. Since disorder is a standard feature of most QSL candidates, this question represents a major challenge for QSL candidates. YbMgGaO$_4$, a triangular lattice antiferromagnet with effective spin-1/2 Yb$^{3+}$ ions, is an ideal system to address this question, since it shows no long-range magnetic ordering with Mg/Ga site disorder. Despite the intensive study, it remains unresolved as to whether YbMgGaO$_4$ is a QSL or in the RS state. Here, through ultralow-temperature thermal conductivity and magnetic torque measurements, plus specific heat and DC magnetization data, we observed a residual $κ_0/T$ term and series of quantum spin state transitions in the zero temperature limit for YbMgGaO$_4$. These observations strongly suggest that a QSL state with itinerant excitations and quantum spin fluctuations survives disorder in YbMgGaO$_4$.

The Levels of Empathy. A Phenomenological Contribution to Psychopathology

Publisher: name: Thaumàzein | Rivista di Filosofia
Year: 2020
Subjects: Empathy; Husserl; Stratification; Phenomenology; Psychopathology

description: The first aim of this paper is to outline some peculiar characteristics of Husserl’s concept of «empathy», that is developed over the years through critical confrontation with Theodor Lipps. Husserl will always be opposed to interpretations of empathy that give too much space to the instinctive and immediate level of the relationship, which seems to him to be a prelude to a failed recognition of otherness. Rather, he will think of empathy as an encounter between people within a shared world. What in some cases is presented as a dichotomy (naturalistic and immediate empathy versus personalistic empathy) can be actually read as a stratification. The second objective of this work will therefore be to outline a stratified theory of empathy, not only in comparison with Husserl, but also with Max Scheler. Surprisingly, however, we already find a first form of stratification, starting in 1912, in the writings of the young doctor Karl Jaspers on phenomenological psychopathology. In the final part of the paper, I will highlight the therapeutic potential present in a similar stratified conception of empathic experiences, by using the Jaspersian theme of “incomprehensible phenomena”.

The catalogs and spectra published here consist of data obtained during the 2005 and 2006 observing sessions of the survey. The catalog consists of 578 HI detections within the range 11h 36m < R.A.(J2000) < 13h 52m and +08 deg < Dec.(J2000) < +12 deg, and cz_sun < 18000 km/s. The catalog entries are identified with optical counterparts where possible through the examination of digitized optical images. The catalog detections can be classified into three categories: (a) detections of high reliability with S/N > 6.5; (b) high velocity clouds in the Milky Way or its periphery; and (c) signals of lower S/N which coincide spatially with an optical object and known redshift. 75% of the sources are newly published HI detections. Of particular note is a complex of HI clouds projected between M87 and M49 that do not coincide with any optical counterparts. Candidate objects without optical counterparts are few. The median redshift for this sample is 6500 km/s and the cz distribution exhibits the local large scale structure consisting of Virgo and the background void and the A1367-Coma supercluster regime at cz_sun ~7000 km/s. Position corrections for telescope pointing errors are applied to the dataset by comparing ALFALFA continuum centroid with those cataloged in the NRAO VLA Sky Survey. The uncorrected positional accuracy averages 27 arcsec ~(21 arcsec ~median) for all sources with S/N > 6.5 and is of order ~21 arcsec ~(16 arcsec ~median) for signals with S/N > 12. Uncertainties in distances toward the Virgo cluster can affect the calculated HI mass distribution.

description: A linear method for inverting noisy observations of the Radon transform is developed based on decomposition systems (needlets) with rapidly decaying elements induced by the Radon transform SVD basis. Upper bounds of the risk of the estimator are established in $L^p$ ($1\le p\le \infty$) norms for functions with Besov space smoothness. A practical implementation of the method is given and several examples are discussed.
The determinants of collective bargaining strategy in the British Columbia hospital industry
Creators: name: Lambert, Paul Gerald
Publisher: name: University of British Columbia
Year: 2010

description: The thesis attempts to illustrate, through the case study approach, the theoretical criteria described in the literature for collective bargaining strategy determination. Based on, a review of the literature a model is presented in which strategy determinants are identified under the general headings of Political and Economic Climate; Relative Power of the Bargaining Parties; Bargaining Structure and Institutional Characteristics; Party Objectives; Legislation; Inter-organizational Relationships; and, Personality. The case studied is the bargaining for the 1976-77 Master Agreement between the Hospital Employees' Union, Local 180, and the Health Labour Relations Association representing the hospitals of British Columbia. In order to put the case into perspective, a discussion of hospital economics is presented. As well, the other labour associations in the hospital industry are introduced, as is the legislation applicable to the negotiations discussed. While the study of a single case prohibits valid generalizations to other bargaining situations, it would appear that political determinants most affect the choice of bargaining strategy.

description: Based on first-principles calculations, we explored the interplay between stacking effect and electron-electron correlation in the layered vdW material of bulk 1T-NbS2 with a 2D charge density wave (CDW) order. Without considering the Coulomb correlation, two energetically favorable out-of-plane stacking configurations are identified: one is a metallic phase with a single-layer stacking pattern, another is a band insulator with a paired-bilayer stacking configuration. Even though the Coulomb correlation is taken into account, the two energetic favorable stacking orders are still far more stable than other stacking orders. Furthermore, increasing the Coulomb interaction, the paired-bilayer stacking configuration transforms from nonmagnetic band insulator to antiferromagnetic insulator, while the single-layer stacking undergoes a Slater-Mott metal-insulator transition, which indicates the non-negligible role of electron-electron correlation interactions. In addition, the electronic structure and magnetic ground state change drastically among different stacking configurations, providing a platform to tune the electronic structures and interlayer magnetic interactions by altering the stacking order. In contrast to the widely accepted scenario of Mott localization as the driving force behind the gap formation in the CDW phase of layered transition metal dichalcogenides, our results not only highlight the crucial role of stacking order in the electronic structures of 1T-NbS2, but also shed fresh light on the distinct effects of Coulomb interaction in different stacking arrangements.

description: We report 75As-NQR/NMR studies on the oxygen-deficient iron(Fe)-based oxypnictide superconductors LaFeAsO_{0.6} (T_c=28 K) along with the results on LaFeAsO, LaFeAsO_{0.75}(T_c=20 K) and NdFeAsO_{0.6}(T_c=53 K). Nuclear spin-lattice relaxation rate 1/T_1 of 75As NQR at zero field on LaFeAsO_{0.6} has revealed a T^3 dependence below T_c upon cooling without the coherence peak just below T_c, evidencing the unconventional superconducting state with the line-node gap. We have found an intimate relationship between the nuclear quadrupole frequencyof 75As and T_c for four samples used in this study. It implies microscopically that the local configuration of Fe and As atoms is significantly related to the T_c of the Fe-oxypnictide superconductors, namely, the T_c can be enhanced up to 50 K when the local configuration of Fe and As atoms is optimal, in which the band structure may be also optimized through the variation of hybridization between As 4p orbitals and Fe 3d orbitals.

description: Recently, it was showed that there is a large N phase transition in Nflation, in which when the number of fields is large enough, the slow roll inflation phase will disappear. In this brief report, we illustrate the phase diagram for Nflation, and discuss the entropy bound and some relevant results. It is found that near the critical point the number of fields saturates dS entropy.

The framing of the miniatures of the benedictional of St. Aethelwold : meaning and function
Creators: name: McKendy, Eilish
Publisher: name: University of British Columbia
Year: 2010

description: The frames surrounding the miniatures of the tenth-century manuscript, "The Benedictional of St. Aethelwold" (British Museum, Add. MS. 49598) are so sumptuous and striking that they almost seem to overwhelm the enclosed scenes. Closer study, however, makes it apparent that the artists used the framing as a device to emphasize the liturgical and royal significance of the scenes, and that a hierarchical plan was envisioned - the more important the feast was to the patron, Bishop Aethelwold of Winchester, the more embellished was the frame. Because very little has been written about framing in general and since no authority has yet examined the significance of the framing of the miniatures in the Benedictional, this thesis examines the interrelationship between the frames and the scenes. Based on the traditional monograph, this study begins with a Preface followed by seven chapters - Description of the manuscript, traditions of framing in manuscripts prior to the Benedictional, components and sources of the Benedictional's frames, colour, overlapping of frame and image, interaction between frame and scene, and conclusion. Each chapter reaches its own conclusion and contains elements which are important as background to the final thesis - that the frames were not merely decorative additions but played a decisive role in enhancing the iconography of the miniatures. The concluding chapter of the thesis, sums up the previous evidence and shows how the hierarchical role played by the frames of the miniatures emphasizes the liturgical and royal content of the scenes. The study suggests that the artists attempted, in a highly conscious way, to underline the political and theological aspects of the monastic reforms initiated by St. Aethelwold, which were a major factor in the revival of the arts in tenth century England, and the formation of the 'Winchester School'.
Anthropogenesis and Technopathy

description: The first part of this paper takes as its starting premise the existence of what was defined by Max Scheler at the start of the 20th century as the coincidence between the psychic and the living (The Human Place in the Cosmos, 1927). The establishment of this coincidence allows us to form a conception of the “psychicity (Psychizität) of life,” i.e. to form a provisional definition of consciousness as manifest expression that both has its roots and extends its highest branches in the evolutive dimension of “the affective”, coming eventually to assume the form and mode particular to “higher-order consciousness”. This higher-order consciousness likely represents the highest level, or the most complex and interconnected level, of the totality of existing manifestations of the vital, understood as the totality of the vital as affectivity, and is today the subject of empirical investigation in the field of the philosophy of neuroscience, a line of inquiry that was anticipated in particular (though not exclusively) by the late 19th and early 20th century philosophical anthropologies of Friedrich Nietzsche, Max Scheler and Viktor von Weizsäcker. The second part of this article, Technopathy, looks at the modern-day pathological “neo-development” of the self, viewed as a progressive distancing of the self from its vital plane, i.e. from the affective. This distancing is generated by an insatiable craving for cognitive consciousness (calculating/quantitative), “animated” by the only passion that it seems to have retained: the passion for technology. Such distancing is pathological in the sense that it results in the regression and erosion of the “animal” passions and affects expressed by the living body, leading potentially to their total eradication. This trend poses a serious threat to the future of humanity.

description: Elastic electromagnetic form factors of nucleons are investigated both for the time-like and the space-like momentums under the condition that the QCD constraints are satisfied asymptotically. The unsubtracted dispersion relation with the superconvergence conditions are used as a realization of the QCD conditions. The experimental data are analyzed by using the dispersion formula and it is shown that the calculated form factors reproduce the experimental data reasonably well.
