description: Αντικείμενο της παρούσας διπλωματικής εργασίας αποτελεί η άποψη του Παρμενίδη για το σεληνιακό φως. Ο Ελεάτης φαίνεται να ήταν ο πρώτος που διαπίστωσε πως η σελήνη είναι μια σφαίρα, η οποία φωτίζεται χάρη στην αντανάκλαση του ηλιακού φωτός πάνω στο σκοτεινό της σώμα. Αρχικά γίνεται μια εισαγωγή στον Παρμενίδη, όπου εξηγείται η δομή του διδακτικού έπους του, κάτι που κρίθηκε απαραίτητο για την ένταξη της σελήνης στο ευρύτερο φιλοσοφικό πλαίσιο του ποιήματος. Στο πρώτο κεφάλαιο παρατίθενται αποσπάσματα από το έπος του Παρμενίδη, καθώς και μεταγενέστερες πηγές που δείχνουν τη συμβολή του Ελεάτη στην κατανόηση της σελήνης. Στο δεύτερο κεφάλαιο παρουσιάζονται οι απόψεις των προκατόχων και σύγχρονων του ποιητή-φιλοσόφου για τη σελήνη, ενώ σε ξεχωριστό κεφάλαιο περιγράφεται λεπτομερώς η θεωρία για το «μεικτό» φως της, της οποίας μάλλον ήταν θιασώτης. Τα αποσπάσματα DK 28 Β 14 – 15, τα μοναδικά σωζόμενα από το έπος που μιλούν για το σεληνιακό φως, εξετάζονται στη συνέχεια. Η ανάλυσή τους οδηγεί στο συμπέρασμα ότι όντως ο Ελεάτης φιλόσοφος υποστήριξε πως η σελήνη ακτινοβολεί χάρη στο ανακλώμενο ηλιακό φως. Τέλος, γίνεται μια απόπειρα τεκμηρίωσης της άποψης πολλών μελετητών ότι ο Παρμενίδης όχι μόνο πίστευε ότι η σελήνη είναι ένα ετερόφωτο σώμα, αλλά ήταν και ο πρώτος που έκανε αυτή τη διαπίστωση. Στον επίλογο επιστρέφουμε στο φιλοσοφικό πλαίσιο του ποιήματος και στο πώς τελικά εντάσσονται μέσα σε αυτό οι απόψεις του Παρμενίδη για το σύμπαν και τη σελήνη
description: The subject of this essay is Parmenides' theory of lunar light. It appears that the Eleatic philosopher was the first who realized that the moon is a sphere that does not have light of its own but shines because it reflects the light of the sun. After an introduction to Parmenides' didactic epic, which relates the moon to the poem's broader philosophical context, the first chapter presents the fragments and testimonies that show the philosopher's contribution to understanding of the moon. The second chapter presents the views of the poet's predecessors and contemporaries on the nature of lunar light, while the next chapter discusses the theory of the double nature of the lunar light, of which Parmenides seemed to have been an adherent. Next we turn to fragments DK 28 B 14 – 15, the only surviving lines from Parmenides' epic which refer to lunar light. Their analysis leads to the conclusion that the Eleatic philosopher indeed believed that the moon borrows its light from the sun and it is bright just as a result of reflection. Finally, we make an attempt to substantiate many scholars' claim that Parmenides not only believed that the lunar light derives from the sun but also discovered this fact

binary integrity protection
revocation

description: The integrity of executable binaries is essential to the security of any device that runs them. At best, a manipulated binary can leave the system in question open to attack, and at worst, it can compromise the entire system by itself. In recent years, supply-chain attacks have demonstrated that binaries can even be compromised unbeknownst to their creators. This, in turn, leads to the dissemination of supposedly valid binaries that need to be revoked later. In this paper, we present and evaluate a concept for publishing and revoking integrity protecting information for binaries, based on the Ethereum Blockchain and its underlying peer-to-peer network. Smart Contracts are used to enforce access control over the publication and revocation of integrity preserving information, whereas the peer-to-peer network serves as a fast, global communication service to keep user clients informed. The Ethereum Blockchain serves as a tamper-evident, publicly-verifiable log of published and revoked binaries. Our implementation incurs costs comparable to registration fees for centralised software distribution platforms but allows publication and revocation of individual binaries within minutes. The proposed concept can be integrated incrementally into existing software distribution platforms, such as package repositories or various app stores.

description: Context:Ajuga ovalifolia Bur. et Franch. var. calantha (Diels) C. Y. Wu et C. Chen (Labiatae), a traditional Chinese medicine, has been used to treat several inflammatory diseases. Objective: To assess the anti-inflammatory activity of ajudecumin A isolated from Ajuga ovalifolia var. calantha, and its possible mechanisms. Materials and methods: Lipopolysaccharide (LPS, 0.5 μg/mL)-stimulated RAW264.7 macrophages were used to assess the anti-inflammatory activity of ajudecumin A (1–40 μM) in vitro. Nitric oxide levels were evaluated by Griess reagent. The mRNA levels of iNOS, COX-2, TNF-α, IL-1β and IL-6 were determined using qRT-PCR. Phosphorylation of ERK, JNK, p38 MAPK and IκBα were detected by western Blot. To further assess the anti-inflammatory of ajudecumin A in vivo, mice were oral treated with ajudecumin A (10 mg/kg) or dexamethasone (0.25 mg/kg, positive control) for 5 days before administration of carrageenan or xylene. Paw and ear edema were then measured, respectively. Results: Ajudecumin A (10–40 μM) decreased LPS-induced nitric oxide production with an IC50 value of 16.19 μM. Ajudecumin A (20 and 40 μM) also attenuated cell spreading and formation of pseudopodia-like structures, and decreased the mRNA levels of iNOS (55.23–67.04%, p < 0.001), COX-2 (57.58–70.25%, p < 0.001), TNF-α (53.75–58.94%, p < 0.01–0.001), IL-1β (79.41–87.85%, p < 0.001) and IL-6 (54.26–80.52%, p < 0.01–0.001) in LPS-activated RAW264.7 cells. Furthermore, ajudecumin A suppressed LPS-induced phosphorylation of ERK, p38 MAPK, and IκBα, as well as IκBα degradation (p < 0.05–0.001). Finally, ajudecumin A (10 mg/kg) attenuated carrageenan- and xylene-induced inflammation in mice by about 28 and 24%, respectively. Discussion and conclusions: Ajudecumin A exhibited a potent anti-inflammatory activity in vitro and in vivo through inhibition on NF-κB and ERK/p38 MAPK pathways, suggesting that ajudecumin A may be potentially developed as a lead compound in anti-inflammatory drug discovery.

description: We present mid-IR N-band $(λ_{eff} = 10.2\micron)$ photometry of a carefully selected sample of T Tauri stars thought to be single from the Taurus-Auriga molecular cloud. Infrared excesses in these stars are generally attributed to circumstellar dust-disks. Combining observations at 2.16$\micron$ (K$_{s}$-band) and 10.2$\micron$ (N-band) we probe a region in the circumstellar dust-disk from a few stellar radii through the terrestrial planet zone (0.02-1.0AU). By analyzing the distribution of the $(K_{s}-N)$ color index with respect to previously measured photometric rotation periods we investigate what role circumstellar disks play in the rotational evolution of the central star. The resulting positive correlation between these two variables is consistent with the notion that a star-disk interaction facilitates the regulation of angular momentum during the T Tauri stage. We also demonstrate, how including non-single stars in such an analysis will \textit{weaken} any correlation in the relation between $(K_{s}-N)$ color and period. To further understand disk properties we also present SEDs for a few objects with new ground based M-band $(λ_{eff} = 4.8\micron)$ and Q-band $(λ_{eff} = 20\micron)$ data and compare them to a geometrically thin, optically-thick disk model.

description: In recent decades, Machine Learning (ML) has become extremely important for many computing applications. The pervasiveness of ultra-low-power embedded devices such as ESP32 or ESP32 Cam with tiny Machine Learning (tinyML) applications will enable the mass proliferation of Artificial Intelligent powered Embedded IoT Devices. In the last few years, the microcontroller device (Espressif ESP32) became powerful enough to be used for small/tiny machine learning (tinyML) tasks. The ease of use of platforms like Arduino IDE, MicroPython and TensorFlow Lite (TF) with tinyML application make it an indispensable topic of research for mobile robotics, modern computer science and electrical engineering. The goal of this paper is to analyze the speed of the Xtensa dual core 32-bit LX6 microprocessor by running a neural network application. The different number of inputs (9, 36, 144 and 576) inputted through the different number of neurons in neural networks with one and two hidden layers. Xtensa LX6 microprocessor has been analyzed because it comes inside with Espressif ESP32 and ESP32 Cam which are very easy to use, plug and play IoT device. In this paper speed of the Xtensa LX6 microprocessor in feed-forward mode has been analyzed.

description: This paper explores multi-armed bandit (MAB) strategies in very short horizon scenarios, i.e., when the bandit strategy is only allowed very few interactions with the environment. This is an understudied setting in the MAB literature with many applications in the context of games, such as player modeling. Specifically, we pursue three different ideas. First, we explore the use of regression oracles, which replace the simple average used in strategies such as epsilon-greedy with linear regression models. Second, we examine different exploration patterns such as forced exploration phases. Finally, we introduce a new variant of the UCB1 strategy called UCBT that has interesting properties and no tunable parameters. We present experimental results in a domain motivated by exergames, where the goal is to maximize a player's daily steps. Our results show that the combination of epsilon-greedy or epsilon-decreasing with regression oracles outperforms all other tested strategies in the short horizon setting.

Japanese market for dimensional lumber : a gravity model approach
Creators: name: Otsuka, Fumiko
Publisher: name: University of British Columbia
Year: 2008

description: The research was done using both descriptive and statistical analyses to investigate the Japanese market for dimensional lumber and how this might affect the demand for wood products from British Columbia. The data was collected from various publications obtained in both Japan and Canada. The descriptive analysis was focused on Japan's domestic forest industry and the Japanese market as lumber importer. The ownership and tenure of Japanese forest land was examined with particular focus on the role of public versus private owners. The financial health of primary operators and owners was also pursued. The level of domestic log and lumber production, prices and uses of timber are identified. Then, the interaction between the Japanese domestic market and the international market for logs and lumber was examined such as activities of major existent importers and the role of trading companies. The statistical analysis of the demand for dimensional lumber was developed. A commodity specific gravity model was utilized to integrate factors both in the supply and demand sides assuming lumber was differentiated by countries of origin. The underlying theories of the gravity model was first examined for the appropriate specification of the empirical model. The variables were also specified based on the information from the descriptive analysis. One conclusion was that non-price variables which indicate power relations between importer and exporter, and among exporters have a significant role in lumber trade with Japan; the variables were production capacities, absorption powers and dummy variables for each of the exporters. In contrast, price variables such as export/import prices, exchange rate have only small impacts on the trade flows. Since Japan's needs for lumber are so diversified, consumers in Japan may choose lumber by their own purpose; prices might be the secondary factor. Finally, as the world's resource market is moving in the direction of sustainable development and resource exporting countries are tightening regulation of their resource export, Japan has been forced to adjust her trade practises.

description: We have selectively grown thin epitaxial GaAs films on Ge substrates with the aid of a 200 nm thin SiO2 mask layer. The selectively grown structures have lateral sizes ranging from 1 um width up to large areas of 1 by 1 mm2. The growth with the standard growth procedure for GaAs growth on Ge substrates reveals a limited amount of GaAs nucleation on the mask area and strong loading effects caused by diffusion of group III precursors over the mask area and in the gas phase. Reduction of the growth pressure inhibits GaAs nucleation on the mask area and reduces the loading effects strongly, but favors the creation of anti phase domains in the GaAs. An optimized growth procedure was developed, consisting of a 13 nm thin nucleation layer grown at high pressure, followed by low pressure growth of GaAs. This optimized growth procedure inhibits the nucleation of GaAs on the mask area and is a good compromise between reduction of loading effects and inhibition of anti phase domain growth in the GaAs. X-ray diffraction and photoluminescence measurements demonstrate the good microscopic characteristics of the selectively grown layers.

description: The heat trace asymptotics on the noncommutative torus, where generalized Laplacians are made out of left and right regular representations, is fully determined. It turns out that this question is very sensitive to the number-theoretical aspect of the deformation parameters. The central condition we use is of a Diophantine type. More generally, the importance of number theory is made explicit on a few examples. We apply the results to the spectral action computation and revisit the UV/IR mixing phenomenon for a scalar theory. Although we find non-local counterterms in the NC $ϕ^4$ theory on $\T^4$, we show that this theory can be made renormalizable at least at one loop, and may be even beyond.

description: We impose the periodicity conditions corresponding to the Matsubara formalism for Thermal Field Theory as constraints in the imaginary time path integral. These constraints are introduced by means of time-independent auxiliary fields which, by integration of the original variables, become dynamical fields in the resulting `dual' representation for the theory. This alternative representation has the appealing property of involving fields which live in one dimension less than the original ones, with a quantum partition function whose integration measure is identical to the one of its classical counterpart, albeit with a different (spatially nonlocal) action.

description: We explore MHD solutions for envelope expansions with core collapse (EECC) with isothermal MHD shocks in a quasi-spherical symmetry and outline potential astrophysical applications of such magnetized shock flows. MHD shock solutions are classified into three classes according to the downstream characteristics near the core. Class I solutions are those characterized by free-fall collapses towards the core downstream of an MHD shock, while Class II solutions are those characterized by Larson-Penston (LP) type near the core downstream of an MHD shock. Class III solutions are novel, sharing both features of Class I and II solutions with the presence of a sufficiently strong magnetic field as a prerequisite. Various MHD processes may occur within the regime of these isothermal MHD shock similarity solutions, such as sub-magnetosonic oscillations, free-fall core collapses, radial contractions and expansions. We can also construct families of twin MHD shock solutions as well as an `isothermal MHD shock' separating two magnetofluid regions of two different yet constant temperatures. The versatile behaviours of such MHD shock solutions may be utilized to model a wide range of astrophysical problems, including star formation in magnetized molecular clouds, MHD link between the asymptotic giant branch phase to the proto-planetary nebula phase with a hot central magnetized white dwarf, relativistic MHD pulsar winds in supernova remnants, radio afterglows of soft gamma-ray repeaters and so forth.

description: We study the thermoelectric performance of $90^0$-bent graphene nanoribbons containing nanopores for optimized design of multiple functional circuits including thermoelectric generators. We show that the thermal conductance of the $90^0$-bent ribbons is lower from few times to an order of magnitude compared to that of pristine armchair and zigzag straight ribbons. Consequently, the thermoelectric performance of the bent ribbons is better than its straight ribbon counterparts, in particular at high temperatures above 500 K. More importantly, the introduction of nanopores is demonstrated to strongly enhance their thermoelectric capacity. At 500 K, the figure of merit ZT increases by more than 160% (from 0.39 without pores to 0.64) with 3 nanopores incorporated, and by more than 200% (up to 0.88) when 24 nanopores are introduced. ZT 1 can be achieved at a temperature of about 1000 K. In addition, the thermoelectric performance is shown to be further improved by adopting asymmetrical leads. This study demonstrates that $90^0$-bent ribbons with nanopores have decent thermoelectric performance for a wide range of temperatures and may find application as efficient thermoelectric converters.

description: The mixed-spin Ising model on a decorated square lattice with two different decorating spins of the integer magnitudes S_B = 1 and S_C = 2 placed on horizontal and vertical bonds of the lattice, respectively, is examined within an exact analytical approach based on the generalized decoration-iteration mapping transformation. Besides the ground-state analysis, finite-temperature properties of the system are also investigated in detail. The most interesting numerical result to emerge from our study relates to a striking critical behaviour of the spontaneously ordered 'quasi-1D' spin system. It was found that this quite remarkable spontaneous order arises when one sub-lattice of the decorating spins (either S_B or S_C) tends towards their 'non-magnetic' spin state S = 0 and the system becomes disordered only upon further single-ion anisotropy strengthening. The effect of single-ion anisotropy upon the temperature dependence of the total and sub-lattice magnetization is also particularly investigated.

description: We have selectively grown thin epitaxial GaAs films on Ge substrates with the aid of a 200 nm thin SiO2 mask layer. The selectively grown structures have lateral sizes ranging from 1 um width up to large areas of 1 by 1 mm2. The growth is fully selective, thanks to an optimized growth procedure, consisting of a 13 nm thin nucleation layer grown at high pressure, followed by low pressure growth of GaAs. This growth procedure inhibits the nucleation of GaAs on the mask area and is a good compromise between reduction of loading effects and inhibition of anti phase domain growth in the GaAs. Nevertheless, both microscopic and macroscopic loading effects can still be observed on x-section SEM images and profilometer measurements. X-ray diffraction and low temperature photoluminescence measurements demonstrate the good microscopic characteristics of the selectively grown GaAs.

description: This paper focuses on building personalized player models solely from player behavior in the context of adaptive games. We present two main contributions: The first is a novel approach to player modeling based on multi-armed bandits (MABs). This approach addresses, at the same time and in a principled way, both the problem of collecting data to model the characteristics of interest for the current player and the problem of adapting the interactive experience based on this model. Second, we present an approach to evaluating and fine-tuning these algorithms prior to generating data in a user study. This is an important problem, because conducting user studies is an expensive and labor-intensive process; therefore, an ability to evaluate the algorithms beforehand can save a significant amount of resources. We evaluate our approach in the context of modeling players' social comparison orientation (SCO) and present empirical results from both simulations and real players.

description: The aim of this research is to investigate how the implementation of the Forest School Concept is associated with the Environmental Ethics and the Environmental Values Education. The case study is about a kindergarten in Cornwall, England, where the Forest School Approach is applied. The data were collected through participatory observation from May till July of 2017. Thematic analysis was used as a data analysis method. The results of this research have shown that at this particular school, the emphasis is mainly given on children gaining knowledge about the environment and living positive direct experiences in the nature, rather than on cultivating environmental values. By observing how the Forest Schools Leaders handle the arising learning opportunities, it was noted that they just model environmental behaviors and attitudes (eco-centric or anthropocentric), while at the same time they do not deliberately use techniques for Teaching Environmental Values.

description: Many proposed scenarios for black hole (BH) mergers involve a tertiary companion that induces von Zeipel-Lidov-Kozai (ZLK) eccentricity cycles in the inner binary. An attractive feature of such mechanisms is the enhanced merger probability when the octupole-order effects, also known as the eccentric Kozai mechanism, are important. This can be the case when the tertiary is of comparable mass to the binary components. Since the octupole strength [$\propto (1-q)/(1+q)$] increases with decreasing binary mass ratio $q$, such ZLK-induced mergers favor binaries with smaller mass ratios. We use a combination of numerical and analytical approaches to fully characterize the octupole-enhanced binary BH mergers and provide analytical criteria for efficiently calculating the strength of this enhancement. We show that for hierarchical triples with semi-major axis ratio $a/a_{\rm out}\gtrsim 0.01$-$0.02$, the binary merger fraction can increase by a large factor (up to $\sim 20$) as $q$ decreases from unity to $0.2$. The resulting mass ratio distribution for merging binary BHs produced in this scenario is in tension with the observed distribution obtained by the LIGO/VIRGO collaboration, although significant uncertainties remain about the initial distribution of binary BH masses and mass ratios.

description: We compute Fourier-resolved X-ray spectra of the Seyfert 1 Markarian 766 to study the shape of the variable components contributing to the 0.3-10 keV energy spectrum and their time-scale dependence. The fractional variability spectra peak at 1-3 keV, as in other Seyfert 1 galaxies, consistent with either a constant contribution from a soft excess component below 1 keV and Compton reflection component above 2 keV, or variable warm absorption enhancing the variability in the 1-3 keV range. The rms spectra, which shows the shape of the variable components only, is well described by a single power law with an absorption feature around 0.7 keV, which gives it an apparent soft excess. This spectral shape can be produced by a power law varying in normalisation, affected by an approximately constant (within each orbit) warm absorber, with parameters similar to those found by Turner et al. for the warm-absorber layer covering all spectral components in their scattering scenario. The total soft excess in the average spectrum can therefore be produced by a combination of constant warm absorption on the power law plus an additional less variable component. On shorter time-scales, the rms spectrum hardens and this evolution is well described by a change in power law slope, while the absorption parameters remain the same. The frequency dependence of the rms spectra can be interpreted as variability arising from propagating fluctuations through an extended emitting region, whose emitted spectrum is a power law that hardens towards the centre. This scenario reduces the short time-scale variability of lower energy bands making the variable spectrum harder on shorter time-scales and at the same time explains the hard lags found in these data by Markowitz et al.

description: Spin alignments of vector mesons and hyperons in relativistic heavy-ion collisions have been proposed as signals of the global polarization. The STAR experiment first observed the $\rm Λ$ polarization. Recently, the ALICE collaboration measured the transverse momentum ($p_T$) and the collision centrality dependence of $K^*$ and $ϕ$ spin alignments in Pb-Pb collisions at $\rm \sqrt{s_{NN}}$ = 2.76 TeV. A large signal is observed in the low $p_T$ region of mid-central collisions for $K^*$ while the signal is much smaller for $ϕ$, and these have not been understood yet. Since vector mesons have different lifetimes and their decay products have different scattering cross sections, they suffer from different hadronic effects. In this paper, we study the effect of hadronic interactions on the spin alignment of $K^*$, $ϕ$ and $ρ$ mesons in relativistic heavy-ion collisions with a multi-phase transport model. We find that hadronic scatterings lead to a deviation of the observed spin alignment matrix element $ρ_{00}$ away from the true value for $ρ$ and $K^*$ mesons (with a bigger effect on $ρ$) while the effect is negligible for the $ϕ$ meson. The effect depends on the kinematic acceptance: the observed $ρ_{00}$ value is lower than the true value when the pseudorapidity ($η$) coverage is small while there is little effect when the $η$ coverage is big. Our study thus provides valuable information to understand the vector meson spin alignment signals observed in the experiments.

Contextualizing the gendered and industrial bias of technology education
Creators: name: O’Riley, Patricia Ann
Publisher: name: University of British Columbia
Year: 2008

description: Technology education in North America has been almost exclusively a male phenomenon. Technology education continues to be taught by males to predominantly males. In addition to excluding females, technology education excludes students from various ethnic, cultural, social and academic groups. Recent revisions of technology education curricula have attempted to address these Inequities. The resulting curricula are purported to be relevant to all students and appropriate to the needs of society. This thesis analyzes the extent to which curricular revisions address the inequities and appropriateness of technology education curricula. My analysis shows that the revised curricula are neither suitable for nor relevant to the needs of most students. Revised curricula support a hegemonic devotion to the 'device paradigm' which permeates much of North American culture, and such hegemony Is a barrier to the development of a form of technological literacy which may empower students to influence rather than simply participate in technological developments. The curricula examined do not explicate the paradigms In which they are situated, nor do they address fundamental questions such as: What purpose should education serve in society? and. What role should technology education play in education generally? Paradigms of traditional and current technology education curricula are identified and elements of critical, Freirian and feminist pedagogy are proposed as promising ways of countering hegemony in education. Since other academic areas may well suffer from similar inequities, and may share the hegemony of technology education, the issues raised In this thesis may be generalizable to other subject areas in education.

description: We have fabricated high-mobility, two-dimensional electron gases in a GaAs quantum well on cylindrical surfaces, which allows to investigate the magnetotransport behavior under varying magnetic fields along the current path. A strong asymmetry in the quantum Hall effect appears for measurements on both sides of the conductive path. We determined the strain at the position of the quantum well. We observe ballistic transport in 8-micrometers-wide collimating structures.

description: We analyze the post-Newtonian orbit of stars around a deformed Kerr black hole. The deformation we consider is a class of disformal transformations of a nontrivial Kerr solution in scalar-tensor theory which are labeled via the disformal parameter $D$. We study different limits of the disformal parameter, and compare the trajectories of stars orbiting a black hole to the case of the Kerr spacetime in general relativity, up to 2PN order. Our findings show that for generic nonzero $D$, the no-hair theorem of general relativity is violated, in the sense that the black hole's quadrupole $Q$ is not determined by its mass $M$ and angular momentum $J$ through the relation $Q=-J^2/M$. Limiting values of $D$ provide examples of simple and exact noncircular metric solutions, whereas in a particular limit, where $1+D$ is small but finite, we obtain a leading correction to the Schwarzschild precession due to disformality. In this case, the disformal parameter is constrained using the recent measurement of the pericenter precession of the star S2 by the GRAVITY Collaboration.

description: Scanning tunneling spectroscopy (STS) is used to study the dynamics of hot electrons trapped on a Cu(100) surface in field emission resonances (FER) above the vacuum level. Differential conductance maps show isotropic electron interference wave patterns around defects whenever their energy lies within a surface projected band gap. Their Fourier analysis reveals a broad wave vector distribution, interpreted as due to the lateral acceleration of hot electrons in the inhomogeneous tip-induced potential. A line-shape analysis of the characteristic constant-current conductance spectra permits to establish the relation between apparent width of peaks and intrinsic line-width of FERs, as well as the identification of the different broadening mechanisms.

Child molesters’ retrospective accounts of their acts and subsequent reasoning on ethical issues
Creators: name: Paris, Faye Ann
Publisher: name: University of British Columbia
Year: 2008

description: The primary purpose of this project was to examine some of the factors which lead child molesters to sexually abuse their victims. To understand why these sexual activities occurred, molesters' own past histories of abuse were considered. To determine how molesters sexually abused children, their approach to selecting, seducing, and silencing the children was examined. The secondary purpose of this project was to evaluate the child molesters' strategies on ethical reasoning tasks after being involved in a sexual relationship with a child . Subjects included twenty convicted male offenders who volunteered to participate while residing at a medium security prison: ten were convicted of extra-familial offences, while the rest were convicted of intra - familial offences. During unstructured interviews, these offenders provided descriptions of their previous sexual experiences, including the sexual activities that occurred with their victims. The semi-structured interviews consisted of meta-ethical tasks measuring the offender's sense of personal continuity over time and skeptical doubt tasks measuring the offender's ability to resolve conflicting issues. These meta-ethical tasks were followed by normative ethical tasks involving three hypothetical dilemmas to measure moral competence and a personal dilemma to measure moral behavior. The results for the unstructured interview supported Marshall's (1989) theory that sex offenders select children that will meet their needs, thus avoiding loneliness. Child molesters reported selecting more non-vulnerable than vulnerable children. Frequently they admitted seducing children through acts of comforting. Not only did they comfort the child , the child would comfort the molester. The majority of child molesters reported they knew the would remain silent about the events that had occurred. The results for the meta-ethical task, personal continuum, indicated that molesters who received the most treatment used higher levels of reasoning. They also used more flexible strategies on the skeptical doubt tasks. For the normative ethical tasks, performance by molesters on the hypothetical dilemmas was more advanced than performance on the personal dilemmas. For the personal dilemmas, the intra-familial offenders in the high-treatment group demonstrated less advanced levels of reasoning than the intra-familial offenders i n the low-treatment group. Further research is needed to clarify these results from a theoretical , empirical and practical level.

description: We present an extensive Monte Carlo investigation of the metastable lifetime through the reversal of the magnetization of spin-$s$ Ising and Blume-Capel models, where $s=\{1/2, 1, 3/2, 2, 5/2, 3, 7/2\}$. The mean metastable lifetime (or reversal time) is studied as a function of the applied magnetic field and for both models is found to obey the Becker-Doring theory, as was initially developed for the case of $s=1/2$ Ising ferromagnet within the classical nucleation theory. Moreover, the decay of metastable volume fraction nicely follows the Avrami's law for all values of $s$ and for both models considered.

description: We report kelvin to millikelvin-temperature measurements of dissipation and frequency shift in megahertz-range resonators fabricated from ultra-nanocrystalline diamond. Frequency shift $δf/f_0$ and dissipation $Q^{-1}$ demonstrate temperature dependence in the millikelvin range similar to that predicted by the glass model of tunneling two level systems. The logarithmic temperature dependence of $δf/ f_0$ is in good agreement with such models, which include phonon relaxation and phonon resonant absorption. Dissipation shows a weak power law, $Q^{-1}\propto T^{1/3}$, followed by saturation at low temperature. A comparison of both the scaled frequency shift and dissipation in equivalent micromechanical structures made of single-crystal silicon and gallium arsenide indicates universality in the dynamical response.
