description: We present a reanalysis of visible/near-infrared (480-930 nm) observations of Neptune, made in 2018 with the MUSE instrument at the Very Large Telescope (VLT) in Narrow Field Adaptive Optics mode, reported by Irwin et al., Icarus, 311, 2019. We find that the inferred variation of methane abundance with latitude in our previous analysis, which was based on central meridian observations only, underestimated the retrieval errors when compared with a more complete assessment of Neptune's limb darkening. In addition, our previous analysis introduced spurious latitudinal variability of both the abundance and its uncertainty, which we reassess here. Our reanalysis of these data incorporates the effects of limb-darkening based upon the Minnaert approximation, which provides a much stronger constraint on the cloud structure and methane mole fraction, makes better use of the available data and is more computationally efficient. We find that away from discrete cloud features, the observed reflectivity spectrum from 800-900 nm is very well approximated by a background cloud model that is latitudinally varying, but zonally symmetric, consisting of a H$_2$S cloud layer, based at 3.6-4.7 bar with variable opacity and scale height, and a stratospheric haze. The background cloud model matches the observed limb darkening seen at all wavelengths and latitudes and we find that the mole fraction of methane at 2-4 bar, above the H$_2$S cloud, but below the methane condensation level, varies from 4-6\% at the equator to 2-4\% at near the south pole, consistent with previous analyses, with a equator/pole ratio of $1.9 \pm 0.2$ for our assumed cloud/methane model. The spectra of discrete cloudy regions are fitted, to a very good approximation, by the addition of a single vertically thin methane ice cloud with opacity ranging from 0 - 0.75 and pressure less than $\sim 0.4$ bar.

description: Response of a normally excited preloaded Hertzian contact is investigated in order to analyze the subharmonic resonance of order 2. The nonlinearity associated with contact losses is included. The method of multiple scales is used to obtain the non-trivial steady state solutions, their stability, and the frequency-response curves. To this end, a third order Taylor series of the elastic Hertzian contact force is introduced over the displacement interval where the system remains in contact. A classical time integration method is also used in conjunction with a shooting method to take into account losses of contact. The theoretical results show that the subharmonic resonance constitutes a precursor of dynamic responses characterised by loss of contact, and consequently, the resonance establishes over a wide frequency range. Finally, experimental validations are also presented in this paper. To this end, a specific test rig is used. It corresponds to a double sphere-plane contact preloaded by the weight of a moving mass. Experimental results show good agreements with theoretical ones.

The epiproct shape for this species is beautifully illustrated in Baumann & Bottorff (1997), however details of epiproct setation were not given. In dorsal aspect, the epiproct has almost parallel sides except for the apex, and in lateral aspect the apical half is expanded but does not exhibit a foot shape as in the other members of the complex. The epiproct tip is rounded and bare but most of the dorsal and lateral surface is covered with a dense pile of setae which extends to the epiproct base, leaving, on either side of the base, an oval bare spot. We provide Figs. 1-5 to permit direct comparisons of these characters with other members of the complex. No eggs were available at the time of the original description, consequently we also add the following brief description of chorionic features. Egg. Outline oval, collar absent. Length ca. 0.35 mm, width ca. 0.23 mm. Chorion completely punctate with coarse, somewhat irregularly spaced, shallow pits (Fig. 6).

description: We have performed 2D hydromagnetic simulations with an adaptive mesh refinement code to examine the response of a pre-existing initially spherical dense core to a non-linear fast-mode wave. One key parameter is the ratio of the wavelength to the initial core radius. If that ratio is large and the wave amplitude is sufficient, significant compression of the core occurs, as envisaged by Myers & Lazarian (1998) in their "turbulent cooling flow" picture. For smaller values of that ratio, an initial value of the ratio of the thermal pressure to magnetic pressure of 0.2, and sufficiently large wave amplitude, the scattering induces the production of dense substructure in the core. This substructure may be related to that detected in the dense core associated with the cyanopolyyne peak in TMC-1. Our simulations also show that short-wavelength waves, contrary to large-wavelength waves, do not confine dense cores.

description: In this paper we investigate the performance of caching schemes based on fountain codes in a heterogeneous satellite network. We consider multiple cache-aided hubs which are connected to a geostationary satellite through backhaul links. With the aimof reducing the average number of transmissions over the satellite backhaul link, we propose the use of a caching scheme based on fountain codes. We derive a simple analytical expression of the average backhaul transmission rate and provide a tightupper bound on it. Furthermore, we show how the performance of the fountain code based caching scheme is similar to that of a caching scheme based on maximum distance separable codes.

Primary caregiving and "mothers with a difference" : A feminist analysis of developments in custody law
Creators: name: Horwitz, Nicole J.
Publisher: name: University of British Columbia
Year: 2009

description: The resolution of child custody disputes is a process fraught with controversy; this dissention has carried over into discussions regarding the perspectives to utilize when analyzing and resolving disputes. There is, however, virtually unanimous belief that the best interests of the child standard has failed to resolve the majority of issues raised in this context. One ground for this consensus is the lack of statutory guidance regarding the weight that should be accorded to the presence or absence of certain factors considered during custody disputes. Many feminist theorists suggest that this lack of guidance results in the operation of bias during the decision-making process. A central theme of this thesis is that societal expectations of a "good" mother operate within the custody realm. These expectations serve to disempower women whose lives are seen as deviating from the normative model. This thesis reviews the historical background to the current best interests of the child standard. It is suggested that children, as well as their primary caregivers, will benefit from a custody standard which focuses on one essential aspect of continuity in a child's life, this being primary caregiving. Enactment of a strong primary caregiver presumption, with a clearly defined "unfitness" rebuttal, is the most effective way to address the concerns of indeterminacy and bias in the custody realm. With this presumption in place, judges, as well as those acting in the "shadow of the law", will be less likely to be governed by arbitrary factors because the permissible scope of inquiry will be drastically reduced. In terms of specific groups of marginalized mothers, this thesis focuses first on the custody rights of lesbian mothers. The denial of custody rights to lesbian mothers may be viewed as one end of the spectrum in which deviations from the dominant ideology of motherhood are penalized. A solution may be found in enacting a primary caregiver presumption which curtails, as much as possible, the operation of this ideology. However, any endorsement of the presumption must entail a consideration of the implications it will have for women who are oppressed on more than gendered grounds, in particular First Nation and disabled mothers. Such implications suggest that any reform must be carefully drafted so as to provide for the many ways in which caregiving may be performed by women. Also integral to this discussion is a consideration of various reform alternatives.

description: It is noted that the Liang-Zhang correlation can be accounted for with the viewing angle interpretation proposed earlier. The Ghirlanda correlation, recently generalized by Nava et al (2006) to a wind profile, can be accounted for by the viewing angle interpretation accordingly generalized to a wind profile. Most of the scatter in the spectra and time-integrated brightness in $γ$-ray bursts (GRB) can thus be accounted for by variation in two parameters, 1) the viewing angle and 2) the jet opening angle, with very little variation in any other intrinsic parameters. The scatter in apparent isotropic equivalent fluence and other parameters is reduced by a factor of order 30 when each of these parameters is considered. Possible difficulties with alternative explanations are briefly discussed. It is also noted that the relative scatter in the Amati and Ghirlanda correlations suggests certain conclusions about the inner engine.

This paper updates the survey of of AI accelerators and processors from last year's IEEE-HPEC paper. This paper collects and summarizes the current accelerators that have been publicly announced with performance and power consumption numbers. The performance and power values are plotted on a scatter graph and a number of dimensions and observations from the trends on this plot are discussed and analyzed. For instance, there are interesting trends in the plot regarding power consumption, numerical precision, and inference versus training. This year, there are many more announced accelerators that are implemented with many more architectures and technologies from vector engines, dataflow engines, neuromorphic designs, flash-based analog memory processing, and photonic-based processing.

description: As is widely known, idioms can be likened to riddles because they are language-specific and unique to each individual language. Translating them from one language to another is nearly impossible. The concept of idioms is not a new issue in linguistics, and extensive research has been conducted on this topic. However, it is worth noting that the matter of idiomaticity remains open-ended, as no definitive consensus has been reached. This article aims to shed light on the analysis of idioms featuring elements of white and black that reflect the inner world of individuals in both the English and Uzbek languages.

description: We observe and study new non-linear global space-time symmetries of the full ghost+matter action of RNS superstring theory. We show that these surprising new symmetries are generated by the special worldsheet currents (vertex operators) of RNS superstring theory, violating the equivalence of superconformal ghost pictures. We review the questions of BRST invariance and non-triviality of picture-dependent vertex operators and show their relation to hidden space-time symmetries and hidden space-time dimensions. In particular, we relate the space-time transformations, induced by the picture-dependent currents, to the symmetries observed in the 2T physics approach.

description: A book review is a multifaceted critical analysis of a book and an evaluation on the quality, value/meaning, significance, and contribution of the book to its own subject/field. It is not a report, summary, or advertisement, rather it is a serious scholarly work. Book reviews have certain functions such as, for academics, being aware of the recently published books and saving time by getting an idea about those publications through reading experts’ evaluations about their significance, value, and contributions; for publishers, finding an opportunity for a kind of advertisement of their publications that mostly remain to a limited environment like academia; for authors, receiving a feedback about their books to enable them to improve them in future editions. Although there is not only one right method for book reviews, because they are personal and reflect the reviewer’s personal ideas and remarks, this note makes suggestions on how to compose an ideal book review after providing a brief description of the nature of book reviews and includes some relevant technical notes hoping to be a helpful guide for those who want to write a book review.

description: We have demonstrated and modeled a simple and efficient method to transfer atoms from a first Magneto-Optical Trap (MOT) to a second one. Two independent setups, with cesium and rubidium atoms respectively, have shown that a high power and slightly diverging laser beam optimizes the transfer between the two traps when its frequency is red-detuned from the atomic transition. This pushing laser extracts a continuous beam of slow and cold atoms out of the first MOT and also provides a guiding to the second one through the dipolar force. In order to optimize the transfer efficiency, the dependence of the atomic flux on the pushing laser parameters (power, detuning, divergence and waist) is investigated. The atomic flux is found to be proportional to the first MOT loading rate. Experimentally, the transfer efficiency reaches 70%, corresponding to a transfer rate up to 2.7x10^8 atoms/s with a final velocity of 5.5 m/s. We present a simple analysis of the atomic motion inside the pushing-guiding laser, in good agreement with the experimental data.

Η μέθοδος φασματικής ανάλυσης διεξήχθη σε Ρ και S τηλεσεισμικά φάσματα, προκειμένου να υπολογιστεί η σεισμική ροπή, το μέγεθος ροπής και η γωνιακή συχνότητα. Οι τιμές που προέκυψαν, χρησιμοποιήθηκαν σε διάφορες εμπειρικές σχέσεις για τον υπολογισμό των διαστάσεων της πηγής, της πτώσης τάσης και της μέγιστης μετάθεσης. Η μέθοδος της αντιστροφής τανυστή ροπής χρησιμοποιήθηκε για τον υπολογισμό του μηχανισμού γένεσης, της σεισμικής ροπής και της χρονικής συνάρτησης πηγής του σεισμού. Το μοντέλο ολίσθησης προσδιορίστηκε με τη μέθοδο της αντιστροφής ολίσθησης. Ένας άλλος στόχος της μελέτης ήταν η διερεύνηση σχετικά με το πώς οι προαναφερθείσες τρεις διαφορετικές τεχνικές μπορούν να συνδυαστούν προκειμένου να επιλυθούν καλύτερα πολύπλοκα σεισμικά γεγονότα.
description: The aim of the present thesis was the determination of the source parameters and the finite fault slip model of the 24 May 2014 North Aegean earthquake, with the application of three methods: spectral analysis, moment tensor inversion and slip inversion of teleseismic data. The spectral analysis method was carried out on P and S teleseismic wave spectra, in order to calculate seismic moment, moment magnitude and corner frequency. The resulted values were input parameters in various empirical relations in order to derive the source dimensions, stress drop and maximum dislocation. The method of moment tensor inversion was used to determine the focal mechanism, seismic moment and source time function of the earthquake. The finite fault slip model was derived by the method of slip inversion. Another aim of this study was the investigation on how the aforementioned three different techniques could be combined in order to best resolve complex seismic events.

description: We have performed broadband color photometry of the twelve brightest irregular satellites of Saturn with the goal of understanding their surface composition, as well as their physical relationship. We find that the satellites have a wide variety of different surface colors, from the negative spectral slopes of the two retrograde satellites S IX Phoebe (S'=-2.5+/-0.4 %/100nm) and S XXV Mundilfari (S'=-5.0+/-1.9 %/100nm) to the fairly red slope of S XXII Ijiraq (S'=19.5+/-0.9 %/100nm). We further find that there exist a correlation between dynamical families and spectral slope, with the prograde clusters, the Gallic and Inuit, showing tight clustering in colors among most of their members. The retrograde objects are dynamically and physically more dispersed, but some internal structure is apparent.

description: If one tries to view de Sitter as a true (as opposed to a meta-stable) vacuum, there is a tension between the finiteness of its entropy and the infinite-dimensionality of its Hilbert space. We invetsigate the viability of one proposal to reconcile this tension using $q$-deformation. After defining a differential geometry on the quantum de Sitter space, we try to constrain the value of the deformation parameter by imposing the condition that in the undeformed limit, we want the real form of the (inherently complex) quantum group to reduce to the usual SO(4,1) of de Sitter. We find that this forces $q$ to be a real number. Since it is known that quantum groups have finite-dimensional representations only for $q=$ root of unity, this suggests that standard $q$-deformations cannot give rise to finite dimensional Hilbert spaces, ruling out finite entropy for q-deformed de Sitter.

description: In this paper we explore the dynamics of ionization bounded planetary nebulae after the termination of the fast stellar wind. When the stellar wind becomes negligible, the hot, shocked bubble depressurizes and the thermal pressure of the photoionized region, at the inner edge of the swept-up shell, becomes dominant. At this stage the shell tends to fragment creating clumps with comet-like tails and long, photoionized trails in between, while the photoionized material expands back towards the central stars as a rarefaction wave. Once that the photoionized gas fills the inner cavity, it develops a kinematical pattern of increasing velocity from the center outwards with a typical range of velociti es starting from the systemic velocity to 50 Km/s at the edges. The Helix nebula is a clear example of a planetary nebula at this late evolutionary stage.

description: Modeling the optical point spread function (PSF) is particularly challenging for adaptive optics (AO)-assisted observations owing to the its complex shape and spatial variations. We aim to (i) exhaustively demonstrate the accuracy of a recent analytical model from comparison with a large sample of imaged PSFs, (ii) assess the conditions for which the model is optimal, and (iii) unleash the strength of this framework to enable the joint estimation of atmospheric parameters, AO performance and static aberrations. We gathered 4812 on-sky PSFs obtained from seven AO systems and used the same fitting algorithm to test the model on various AO PSFs and diagnose AO performance from the model outputs. Finally, we highlight how this framework enables the characterization of the so-called low wind effect on the SPHERE instrument and piston cophasing errors on the Keck II telescope. Over 4812 PSFs, the model reaches down to 4% of error on both the Strehl-ratio (SR) and full width at half maximum (FWHM). We particularly illustrate that the estimation of the Fried parameter, which is one of the model parameters, is consistent with known seeing statistics and follows expected trends in wavelength using the MUSE instrument ($λ^{6/5}$) and field (no variations) from GSAOI images with a standard deviation of 0.4cm. Finally, we show that we can retrieve a combination of differential piston, tip, and tilt modes introduced by the LWE that compares to ZELDA measurements, as well as segment piston errors from the Keck II telescope and particularly the stair mode that has already been revealed from previous studies. This model matches all types of AO PSFs at the level of 4% error and can be used for AO diagnosis, post-processing, and wavefront sensing purposes.

Consequently, we offer Figs. 7- 12 and the following comments to document these characters for S. tamalpa. The typical epiproct has a pointed, bare apex and a completely bare base (Fig. 8). The apex is foot shaped in lateral aspect (Fig. 9), but is not upturned at the “ankle” as in S. yurok. The egg lacks a collar and is coarsely pitted over most of the chorionic surface, but a small apical area is smooth (Fig. 12).

description: The electronic structure of the new superconductor, SmO$_{1-x}$F$_x$FeAs ($x=0.15$), has been studied by angle-integrated photoemission spectroscopy. Our data show a sharp feature very close to the Fermi energy, and a relative flat distribution of the density of states between 0.5 eV and 3 eV binding energy, which agrees best with band structure calculations considering an antiferromagnetic ground state. No noticeable gap opening was observed at 12 Kelvin below the superconducting transition temperature, indicating the existence of large ungapped regions in the Brillouin zone.

description: Η παρούσα διπλωματική εργασία, πραγματεύεται το φαινόμενο του κοινωνικού αποκλεισμού, τόσο από κοινωνιολογική, όσο και από θεολογική σκοπιά. Το πρώτο μέρος, παρουσιάζει τον κοινωνικό αποκλεισμό σαν ένα κοινωνιολογικό πρόβλημα, μείζονος σημασίας. Υπό το πρίσμα της κοινωνιολογίας, αναλύονται όροι και έννοιες, θίγονται ζητήματα όπως το μεταναστευτικό, η επανένταξη των κρατουμένων στο σύνολο της κοινωνίας, η λαίλαπα των ναρκωτικών, η οποία στις μέρες μας έχει πάρει ανεξέλεγκτες διαστάσεις και η μάστιγα του AIDS. Στο δέυτερο μέρος, αναλύονται οι όροι της περιθωριοποίησης, του κοινωνικού αποκλεισμού, της αγάπης και της φιλανθρωπίας, αλλά και της έννοιας της δικαιοσύνης, υπό το θεολογικό πρίσμα. Η αγάπη και η φιλανθρωπία, δυο έννοιες παράλληλες και αλληλένδετες μεταξύ τους, είναι το «όπλο» για την αντιμετώπιση του φαινομένου. Η αγάπη πρώτα προς το Δημιουργό και ύστερα προς τα δημιουργήματά Του, είναι η αρχή για την εξάλειψη της περιθωριοποίησης των ανθρώπων. Παρακάτω, γίνεται μια αναφορά στην έννοια της δικαιοσύνης, όπως εκείνη φανερώνεται διδάσκεται και επιδιώκεται πολλές φορές, στην Παλαιά και την Καινή Διαθήκη.
description: This senior thesis treats the phenomenon of social seclusion, both under a theological and a sociological approach. In the first part, presents social seclusion as a sociological issue of outmost importance. The term of social seclusion is analyzing and finally, on sociological point of view, issues like immigration, prisoner rehabilitation, drugs and AIDS are addressed. In the second part, terms like marginalization, social seclusion, love and charity are analyzed as well as the significance of justice, under a theological view. Love and charity, two parallel and interconnected terms, is the “weapon” for addressing the issue. Love, towards the Creator as well as towards its “creations”, is the starting point for the eradication of human marginalization. In the present thesis, there is also a reference to justice, as it is mentioned, tutored and many times sought after, both in the Old and in the New Testament.

description: In various cases of decision analysis we use two popular methods: Analytical Hierarchical Process (AHP) and Fuzzy based AHP or Fuzzy AHP. Both the methods deal with stochastic data and can determine decision result through Multi Criteria Decision Making (MCDM) process. Obviously resulting values of the two methods are not same though same set of data is fed into them. In this research work, we have tried to observe similarities and dissimilarities between two methods outputs. Almost same trend or fluctuations in outputs have been seen for both methods for same set of input data which are not consistent. Both method outputs ups and down fluctuations are same for fifty percent cases.

description: K strings in Yang-Mills theory can be considered as bound states of k elementary confining strings carrying one unit of colour flux. Current estimates of k-string tension sigma_k are very sensitive to the leading corrections due to quantum fluctuations of the string. In this study we address this problem by comparing Polyakov-Polyakov correlators in the fundamental representation (k=1) with the corresponding ones with k=2 in the confining phase of a Z_4 gauge theory in three dimensions. Highly efficient simulation techniques are available in this case. Although the k=1 Polyakov-Polyakov correlator matches nicely with the expected bosonic string effects up to the Next-to-Leading-Order, the k=2 Polyakov-Polyakov correlators show large deviations. This is an important source of potential systematic errors in the current estimates of sigma_k.

description: Η παρούσα διπλωματική ερευνητική μελέτη έχει ως αντικείμενο «το δημοσιογραφικό έργο ως πνευματικό έργο». Σκοπός της μελέτης είναι να εξετάσει διαδοχικά, την προστασία που αναγνωρίζει η πνευματική ιδιοκτησία στον επαγγελματία δημοσιογράφο (μισθωτό ή ελεύθερο επαγγελματία), του οποίου οι πνευματικές συμβολές, σε ψηφιακή μορφή, αναδημοσιεύονται από τον εκδότη ή οποιονδήποτε χρήστη στο διαδίκτυο για on line επικοινωνία και στο δημοσιογράφο blogger (ο οποίος μπορεί να είναι είτε επαγγελματίας είτε και απλός πολίτης που συντηρεί δικό του ιστολόγιο) όσον αφορά τη χρήση και εκμετάλλευση των προσωπικών πνευματικών του συμβολών στο διαδίκτυο. Η εργασία αποτελείται από ένα θεωρητικό μέρος, όπου γίνεται μια ιστορική αναφορά στο επάγγελμα του δημοσιογράφου και στο έργο του, το οποίο αποτελεί αντικείμενο προστασίας πνευματικών δικαιωμάτων, και σε ένα πρακτικό μέρος, όπου γίνεται μια ερευνητική προσπάθεια να παρουσιαστούν χαρακτηριστικές περιπτώσεις κειμένων δημοσιογραφικού λόγου, στις οποίες εμφιλοχωρεί η δυνατότητα προστασίας του δημοσιογράφου ως δημιουργού και του κειμένου του ως πνευματικού έργου. Η χρησιμότητα της εργασίας συνίσταται στο να αναδείξει τις σχέσεις του δημοσιογραφικού επαγγέλματος με την πνευματική ιδιοκτησία, τα δικαιώματα του δημοσιογράφου κατά την αναδημοσίευση του πνευματικού έργου του στο διαδίκτυο, από τον εκδότη ή τον ιδιοκτήτη του εντύπου καθώς και από οποιονδήποτε άλλο χρήστη, ο οποίος έχει τη δυνατότητα να «καταναλώσει» το δημοσιογραφικό έργο μέσω της διάχυσής του στο διαδίκτυο.
description: This thesis research study focuses on "journalistic work as spiritual work". The purpose of the study is to successively examine the protection conferred by copyright to the professional journalist (employee or self-employed), whose spiritual contributions, in digital form, reproduced by the issuer or any user on the internet on line communication and the blogger journalist (who may be either a professional or a private citizen and that maintains his own blog) regarding the use and exploitation of personal copyright of one's own contributions online. The work consists of a theoretical part, where there is a historical reference to the profession of journalist and his work, which is subject to copyright protection, and a practical part, where there is an effort to present typical situations of journalistic discourse texts, where there is potential to protect the journalist as author and the text as intellectual work. The usefulness of the work is to highlight the relationship of journalism with intellectual property, the rights of journalist by the reproduction of his intellectual work on the internet, from the issuer or the owner of the form and by any other user, who has the ability to "consume" the journalistic work through its diffusion on the Internet.

description: We present HI observations of 54 galaxies in the Pegasus cluster. The observations include single dish HI measurements, obtained with the Arecibo telescope for all 54 galaxies in the sample, as well as HI images, obtained with the VLA for 10 of these. The Arecibo profiles reveal an overall HI deficiency in the cluster, with ~40% of the galaxies in the core of the cluster showing modest deficiencies of typically a factor of 2-3. The HI morphology of some galaxies shows that the HI disk is smaller than the optical disk and slightly offset from the stars. We find a correlation between HI deficiency and the ratio of the HI disk size to optical disk size. More HI deficient galaxies have relatively smaller HI disks, a configuration that is usually attributed to an interaction between the ISM of the galaxy and the hot ICM. Such a result is surprising since the Pegasus cluster has a low level of X-ray emission, and a low velocity dispersion. The low velocity dispersion, coupled with the lack of a dense hot ICM indicate that ram pressure stripping should not play a significant role in this environment. In addition, two of the galaxies, NGC7604 and NGC7648, are morphologically peculiar. Their peculiarities indicate contradictory scenarios of what is triggering their unusual star formation. Halpha imaging, along with long-slit spectroscopy of NGC7648 reveal morphological features which point to a recent tidal interaction. On the other hand, Halpha imaging,along with VLA HI mapping, of NGC7604 reveal morphological features suggestive of a ram pressure event. Our data indicate that ISM-ICM interactions may play a role in a wider variety of environments than suggested by simple ram pressure arguments.

description: We have measured, in real time, individual quasiparticle tunneling in a single Cooper pair transistor, using rf reflectometry on the supercurrent branch. We have extracted the even-to-odd and odd-to-even transition rates directly by analyzing the distributions of dwell times in the even and odd states of the transistor. We discuss both the measurement and analysis techniques and report on the temperature and gate dependence of the quasiparticle tunneling rates.

The concept of legitimate governance in the contemporary municipal and international legal systems: an interdisciplinary analysis
Creators: name: Okafor, Obiora Chinedu
Publisher: name: University of British Columbia
Year: 2009

description: All over today's world, there exists a crisis of legitimate governance concerning the acquisition and (ab)use of governmental power. Given the undesirable consequences of this crisis, is it possible, as a first step in the struggle to eliminate it, to construct a workable normative (rather than descriptive) model for the evaluation of governance as legitimate or illegitimate? Do reasonably determinate rules exist within international law which collectively provide a barometer for the assessment of governance as illegitimate? If so, does the concept of legitimate governance as reflected by these rules address the widespread inequities in the socioeconomic relations of power within and without municipal polities? If not, is such a concept of political legitimacy not defective? Are there normative or other consequences that flow from a determination that a regime is illegitimate? What is the character of the process by which such a determination is made by the international community? And is that community itself a legitimate evaluator of municipal governance? I have utilised knowledge from within and without law; sought to integrate the operation of international and municipal norms; gone beyond doctrine to explore the forces outside of law that constrain the operation of law; and adopted an evaluative view of the concept of legitimacy. I conclude that there are norms in contemporary international law which constitute useful criteria for the evaluation of municipal governance. I have, however, lamented the disregard with which international law has treated the need for socio-economic equity within and between states, when such equity is an imperative for political legitimacy. I also argue that the process of international legitimation needs re-alignment in the service of legitimacy norms. I conclude by exposing the crisis of legitimacy that faces the present system of global governance, arguing that if that system is to remain credible, and therefore effective, in the regulation of municipal governance, then it must be overhauled to critically reduce the selectivity and partiality which it now often displays.

description: Subsequent to the early Universe quark-hadron transition the universal baryon number is carried by nucleons: neutrons and protons. The total number of nucleons is preserved as the Universe expands, but as it cools lighter protons are favored over heavier neutrons reducing the average mass per baryon. During primordial nucleosynthesis free nucleons are transformed into bound nuclides, primarily helium, and the nuclear binding energies are radiated away, further reducing the average mass per baryon. In particular, the reduction in the average mass per baryon resulting from Big Bang Nucleosynthesis (BBN) modifies the numerical factor relating the baryon (nucleon) mass and number densities. Here the average mass per baryon, m_B, is tracked from the early Universe to the present. The result is used to relate the present ratio of baryons to photons (by number) to the present baryon mass density at a level of accuracy commensurate with that of recent cosmological data, as well as to estimate the energy released during post-BBN stellar nucleosynthesis.

description: Σε μια εποχή που το σύγχρονο σχολείο έχει στόχο να υποστηρίξει όλους τους μαθητές αλλά και σε μια εποχή όπου κυριαρχούν οι αυξανόμενες απαιτήσεις για την εκπαίδευση των μαθητών με αναπηρία ή ειδικές εκπαιδευτικές ανάγκες δημιουργήθηκε η ανάγκη για Συμβουλευτική στην Ειδική Αγωγή. Αποτέλεσμα της ανάγκης αυτής είναι η διεύρυνση του ρόλου του ειδικού παιδαγωγού. Ο ρόλος του που βρίσκεται μεταξύ της διδακτικής και ψυχολογικής υποστήριξης των παιδιών με ειδικές εκπαιδευτικές ανάγκες αποκτά πλέον συμβουλευτική διάσταση. Το συμβουλευτικό έργο που μπορεί να ασκήσει ο ειδικός παιδαγωγός στο πλαίσιο της καθημερινής ζωής στο σχολείο έχει ως αποδέκτες τους μαθητές, τους γονείς αλλά και το υπόλοιπο προσωπικό του σχολείου. Η παρούσα μεταπτυχιακή εργασία επιχειρεί να μελετήσει μέσα από μια ευρεία ανασκόπηση βιβλιογραφίας τη σύνδεση της Ειδικής Αγωγής και της Συμβουλευτικής, το ρόλο του ειδικού παιδαγωγού με τους μαθητές του αλλά και τις οικογένειες τους και κυρίως την ανάδειξη της συμβουλευτικής διάστασης του ρόλου του.
description: At a season where the modern school aims to support all students and in a season where dominate the increasing requirements for the education students with disabilities or special educational needs created the need for Counseling in Special Education. Result of this need is the expansion of the role of the special educator. His role that is found between the instructive and psychological support of children with special educational needs acquires henceforth counseling dimension. Special educator’s counseling activity in the frame of daily life in the school has as recipients the students, the parents and the remainder personnel of school. This thesis is an attempt to study through a comprehensive review of literature the connection of the Special Education and Counseling, the role of the special teacher with his students and their families and mainly the appointment of counseling dimension of teacher’s role.
