The Kashmir conflict : A case study in ethno-nationalism and its ramifications for India’s national security
Creators: name: Shungur, Shantarene
Publisher: name: University of British Columbia
Year: 2009

description: In this dissertation I am concerned with 3 objectives: (1) To determine the nature of India's security dilemma in Kashmir. (2) To show that the Indo-Pakistan commitment to the nuclear weapons option makes it imperative that conflict management is augmented by mechanisms of conflict resolution. (3) To proffer a solution to the crisis that will address the structural constraints of the Indo-Pakistan "insecurity complex" and account for the internal and external causes of the present imbroglio. First, I shall argue that Kashmir poses a dual internal-external security problem for India. The internal component of threat which involves the rising tide of militant Kashmiri ethno-nationalism, and its cries for separation from the Indian union, has been caused by two factors: the steady erosion of the nation's democratic, federal, and secular edifice, and New Delhi's continued neglect of the state's socio-economic needs. I contend that as Indian security forces become mired in a counter-insurgency war against Kashmiri militants, it appears that New Delhi is unwittingly aiding and abetting the very process of fragmentation that she so desperately wants to prevent These internal security problems have been compounded by Pakistan's irredentist claims and actions in Kashmir. The external component of threat involving Pakistan's covert support of disaffected elements in the troubled state has thus sustained the conflict Second, I shall determine the prospects for a fourth Indo-Pakistan war involving Kashmir as the bone of contention. I maintain that the risks of nuclear war between India and Pakistan are greater than deterrence advocates suggest because of the political dynamics which obtain and the weaknesses of the command, control, communication and information systems in both countries. To illustrate this point, I shall examine the causes of the May 1990 confrontation between India and Pakistan in which escalation to a nuclear level was quite possible. Finally, I shall argue that a window of opportunity has been created in the international context of the 1990s in which the conditions for dispute resolution depend upon the reformation of the Indian and Pakistani systems of domestic governance. The most effective way to check centrifugal tendencies unleashed by the assertion of sub-national loyalties is to rejuvenate Indian democracy, federalism and secularism. In order to reverse the pattern of enmity that has historically structured Indo-Pakistan relations, Pakistan must endeavor to restructure and rethink its political institutions and political practises. Pakistan must keep the psychology of the military out of civilian governance, develop a polity that is more "federal" in character, and improve the standard of living for the masses. In short, once both countries put their domestic houses in order, one can envisage an end to the crisis in Kashmir.

description: Recently, in Phys. Rev. Lett. 95, 140601 (2005), P. Grassberger addresses the interesting issue of the applicability of q-statistics to the renowned Feigenbaum attractor. He concludes there is no genuine connection between the dynamics at the critical attractor and the generalized statistics and argues against its usefulness and correctness. Yet, several points are not in line with our current knowledge, nor are his interpretations. We refer here only to the dynamics on the attractor to point out that a correct reading of recent developments invalidates his basic claim.

description: Οι ραγδαίες εξελίξεις της ιατρικής και η αλματώδης ανάπτυξη της βιοτεχνολογίας εισήγαγαν νέες μεθόδους παροχής υγείας που καθιστούν το θέμα του θανάτου ενδιαφέρον και έντονα αμφιλεγόμενο. Ένα από τα σημαντικότερα θέματα που θίγονται είναι αυτό του ανώδυνου θανάτου, ήτοι της ευθανασίας. Οι απόψεις επ' αυτού διίστανται, καθώς το κάθε ένα επιστημονικό πεδίο έχει μία διαφορετική απάντηση να δώσει και ενώ κάποιες εκ των θέσεων συγκλίνουν, οι περισσότερες παρουσιάζουν μεγάλες διαφορές ως προς τον τρόπο προσέγγισης της ευθανασίας. Κοινή αφετηρία είναι βέβαια ο άνθρωπος αλλά και στον ορισμό του ανθρώπου η κάθε επιστήμη έχει τη δική της θέση. Η ιατρική, η νομική, η κοινωνιολογία, η ψυχολογία και η θεολογία διαδραματίζουν το σημαντικότερο ρόλο στη συζήτηση, χωρίς όμως να καταλήγουν σε μία κοινή θέση, αφού είναι πρακτικά αδύνατο να υποχωρήσουν περισσότερο ή λιγότερο σε ένα θέμα όπως ο θάνατος. Η ιατρική, όπως θα δούμε παρακάτω, δεν εφηύρε την ευθανασία αλλά με τις λύσεις που προσέφερε στο σύγχρονο άνθρωπο σε θέματα υγείας, μεγιστοποίησε το παγκόσμιο ενδιαφέρον και προβλημάτισε την κοινή γνώμη.
description: The rapid developments in medicine and the rapid development of biotechnology have introduced new methods of providing health makes the issue of death and interest highly controversial. One of the main issues raised is that of a painless death, or euthanasia. The opinions on this differ, and each scientific field has a different answer to give, and some of the positions converge, most are large differences in the approach to euthanasia. Common starting point is certainly the man and the definition of man, each science has its own position. Medicine, law, sociology, psychology and theology played a role in the debate, but arrive at a common position, since it is practically impossible to fall more or less on a topic like death. The medicine, as we shall see below, not invented euthanasia, but the solutions offered in the modern human health, maximizing the global interest and puzzled the public.

description: We propose simple randomized strategies for sequential prediction under imperfect monitoring, that is, when the forecaster does not have access to the past outcomes but rather to a feedback signal. The proposed strategies are consistent in the sense that they achieve, asymptotically, the best possible average reward. It was Rustichini (1999) who first proved the existence of such consistent predictors. The forecasters presented here offer the first constructive proof of consistency. Moreover, the proposed algorithms are computationally efficient. We also establish upper bounds for the rates of convergence. In the case of deterministic feedback, these rates are optimal up to logarithmic terms.

description: In this work, we explore the benefits of using multilingual bottleneck features (mBNF) in acoustic modelling for the automatic speech recognition of code-switched (CS) speech in African languages. The unavailability of annotated corpora in the languages of interest has always been a primary challenge when developing speech recognition systems for this severely under-resourced type of speech. Hence, it is worthwhile to investigate the potential of using speech corpora available for other better-resourced languages to improve speech recognition performance. To achieve this, we train a mBNF extractor using nine Southern Bantu languages that form part of the freely available multilingual NCHLT corpus. We append these mBNFs to the existing MFCCs, pitch features and i-vectors to train acoustic models for automatic speech recognition (ASR) in the target code-switched languages. Our results show that the inclusion of the mBNF features leads to clear performance improvements over a baseline trained without the mBNFs for code-switched English-isiZulu, English-isiXhosa, English-Sesotho and English-Setswana speech.

Subsequently, such application is made concrete with the assistance of a case study. Specifically, we investigate and then discuss a model of stiff matter in a spatially flat homogeneous and isotropic universe. A new quantum cosmological solution, where fractional calculus implications are explicit, is presented and then contrasted with the corresponding standard quantum cosmology setting.

description: The effects of networking on the extent of cooperation emerging in a competitive setting are studied. The evolutionary snowdrift game, which represents a realistic alternative to the well-known Prisoner's Dilemma, is studied in the Watts-Strogatz network that spans the regular, small-world, and random networks through random re-wiring. Over a wide range of payoffs, a re-wired network is found to suppress cooperation when compared with a well-mixed or fully connected system. Two extinction payoffs, that characterize the emergence of a homogeneous steady state, are identified. It is found that, unlike in the Prisoner's Dilemma, the standard deviation of the degree distribution is the dominant network property that governs the extinction payoffs.

description: The motion of a spin excitation across topologically non-trivial magnetic order exhibits a deflection that is analogous to the effect of the Lorentz force on an electrically charged particle in an orbital magnetic field. We used polarized inelastic neutron scattering to investigate the propagation of magnons (i.e., bosonic collective spin excitations) in a lattice of skyrmion tubes in manganese silicide. For wave vectors perpendicular to the skyrmion tubes, the magnon spectra are consistent with the formation of finely spaced emergent Landau levels that are characteristic of the fictitious magnetic field used to account for the nontrivial topological winding of the skyrmion lattice. This provides evidence of a topological magnon band structure in reciprocal space, which is borne out of the nontrivial real-space topology of a magnetic order.
Unified static renormalization-group treatment of finite-temperature crossovers close to a quantum critical point

description: A nonconventional renormalization-group (RG) treatment close to and below four dimensions is used to explore, in a unified and systematic way, the low-temperature properties of a wide class of systems in the influence domain of their quantum critical point. The approach consists in a preliminary averaging over quantum degrees of freedom and a successive employment of the Wilsonian RG transformation to treat the resulting effective classical Ginzburg-Landau free energy functional. This allows us to perform a detailed study of criticality of the quantum systems under study. The emergent physics agrees, in many aspects, with the known quantum critical scenario. However, a richer structure of the phase diagram appears with additional crossovers which are not captured by the traditional RG studies. In addition, in spite of the intrinsically static nature of our theory, predictions about the dynamical critical exponent, which parametrizes the link between statics and dynamics close to a continuous phase transition, are consistently derived from our static results.

We here review recent progress in understanding the assembly process of the first galaxies, starting with cosmological initial conditions and modelling the detailed physics of star formation. In particular, we study the role of HD cooling in ionized primordial gas, the impact of UV radiation produced by the first stars, and the propagation of the supernova blast waves triggered at the end of their brief lives. We conclude by discussing how the chemical abundance patterns observed in extremely low-metallicity stars allow us to probe the properties of the first stars.

description: We summarize our recent results on the phase diagram of QCD with N_f=2+1 quark flavors, as a function of temperature T and quark chemical potential μ. Using staggered fermions, lattices with temporal extent N_t=4, and the exact RHMC algorithm, we first determine the critical line in the quark mass plane (m_{u,d},m_s) where the finite temperature transition at μ=0 is second order. We confirm that the physical point lies on the crossover side of this line. Our data are consistent with a tricritical point at (m_{u,d},m_s) = (0,\sim 500) MeV. Then, using an imaginary chemical potential, we determine in which direction this second-order line moves as the chemical potential is turned on. Contrary to standard expectations, we find that the region of first-order transitions shrinks in the presence of a chemical potential, which is inconsistent with the presence of a QCD critical point at small chemical potential. The emphasis is put on clarifying the translation of our results from lattice to physical units, and on discussing the apparent contradiction of our findings with earlier lattice studies.

description: Multiparticle production at high energies is described in terms of color strings stretched between the projectile and target. As string density increases, overlap among the strings leads to cluster formation. At some critical density a macroscopic cluster appears, spanning the entire system. This marks the percolation phase transition. Data from p+p, d+Au and Au+Au collisions at 200 GeV has been analyzed using the STAR detector to obtain the percolation density parameter, $η$. For 200 GeV Au+Au collisions, the value of $η$ is found to lie above the critical percolation threshold, while for 200 GeV d+Au collisions it is below the critical value. This supports the idea of string percolation, which at high enough string density is a possible mechanism to explore the hadronic phase transition to a quark-gluon plasma.

description: We study Si:P donor electron spin decoherence due to anisotropic hyperfine (AHF) interaction with the surrounding nuclear spin bath. In particular, we clarify the electron spin echo envelope modulation (ESEEM) in the Si:P system and the resonancelike contributions from nuclear spins in various shells away from the P atoms. We suggest an approach to minimize AHF-induced decoherence by avoiding the resonances and orienting an applied magnetic field along directions that can periodically eliminate contributions from the dominant nearest neighbor atoms. Our remarkable agreement with experiment demonstrates nearly complete understanding of electron spin decoherence in Si:P when combining ESEEM, spectral diffusion, instantaneous diffusion, and spin-lattice relaxation.

description: The observation of ferroelectric, ferromagnetic and ferroelastic phases in thin films of binary oxides attract the broad interest of scientists and engineers. However, the theoretical consideration of observed behaviour physical nature was performed mainly for HfO2 thin films from the first principles, and in the framework of Landau-Ginzburg-Devonshire (LGD) phenomenological approach with a special attention to the role of oxygen vacancies in both cases. Allowing for generality of the LGD theory we applied it to the group of binary oxides in this work. The calculations have been performed in the assumption that oxygen vacancies, as elastic dipoles, can be partially transformed into electric dipoles due to the defect site-induced and/or surface-induced inversion symmetry breaking (via e.g. piezoelectric effect), and can "migrate" entire the depth of an ultra-thin film. We calculated the dependence of the film polarization on the applied voltage for room temperature and different film thickness. Since the many films of binary oxide are ferroelectric and ferromagnetic due to the same oxygen vacancies, they can be multiferroics. Performed calculations have shown that thin films of binary oxides can be considered as a new wide class of multiferroics with broad spectra of physical properties useful for application in nanoelectronics and nanotechnology. The properties can be controlled by the choice of oxygen vacancies concentration, film thickness and special technological treatment, such as annealing.

description: We present the first results from the Distant Radio Galaxies Optically Non-detected in the SDSS (DRaGONS) Survey. Using a novel selection technique for identifying high redshift radio galaxy (HzRG) candidates, a large sample of bright (S_{1.4GHz} > 100mJy) radio sources from the FIRST survey having no optical counterpart in the SDSS is compiled. K-band imaging with the FLAMINGOS instrument on the 4-meter telescope at Kitt Peak for 96 such candidates allows preliminary identification of HzRG candidates through the well-known K-z relation. Of the initial candidates, we identify 70 with magnitudes brighter than K \approx 19.5, and compute limiting magnitudes for the remainder. Assigning redshifts based on the K-z Hubble diagram gives a mean redshift for our sample of z=2.5 and a median redshift of z=2.0. This selection is also sensitive to a previously unseen population of anomalously red radio galaxies (r-K > 6.5-7), which may indicate significant obscuration at moderate redshifts. These obscured objects can be used to test the completeness of QSO surveys to the effects of reddenning. More than ten percent of our sample falls into this category, which may represent a sizable radio loud population missing from current optically selected AGN samples. We additionally identify 479 bright Extremely Red Objects (EROs) in the fields surrounding our HzRG candidates, to a magnitude of K=17.5, within a non-contiguous area of 2.38 square degrees. This constitutes a small overdensity of EROs surrounding the radio galaxy candidates over random fields, and we see possible evidence for a physical association of the EROs with the radio galaxies. However, examining the clustering of all K < 19.0 galaxies around the radio targets reveals no evidence of a global galaxy excess.

description: In previous experiments, Trichoderma sp. BI 7376 and Pseudomonas chlororaphis subsp. aurantiaca BI 7439, applied as seed treatments, controlled soilborne Fusarium culmorum on maize. The current paper is focused on a deeper characterization of the effects of both strains. The experiments were conducted as pot tests with artificial inoculation of the substrate with F. culmorum, or with maize seed lots infected with Fusarium spp. When seeds were treated with Trichoderma strain BI 7376, Pseudomonas strain BI 7439 or with the chemical active ingredient thiram and stored before they were sown in substrate inoculated with F. culmorum, the protection by all agents declined. During the storage period of 211 days, the activity of thiram and Trichoderma strain BI 7376 dropped by about 38% and 57%, respectively. After 36 days of storage, Pseudomonas strain BI 7439 failed to provide any protection, which was obviously related to the observed total loss of viable cells of this agent. Moreover, we observed that both strains protected against soilborne F. subglutinans and F. verticillioides, showing that their activity was not limited to F. culmorum which was used in the previous experiments. Further, experiments with seed lots suspected or known to be infected with Fusarium species indicated that Trichoderma strain BI 7376 also controlled seedborne inoculum. When electron seed treatment was followed by application of Trichoderma strain BI 7376, both seed- and soilborne infections were controlled, showing that the concept of using a combination of a physical seed treatment and microbial antagonists appears feasible.

description: Transition metal dichalcogenides (TMDs), exhibit a range of crystal structures and topological quantum states. The 1$T$ phase, in particular, shows promise for superconductivity driven by electron-phonon coupling, strain, pressure, and chemical doping. In this theoretical investigation, we explore 1$T$-RhSeTe as a novel type of TMD superconductor with topological electronic states. The optimal doping structure and atomic arrangement of 1$T$-RhSeTe are constructed. Phonon calculations validate the integrity of the constructed doping structure. The analysis of the electron-phonon coupling (EPC) using the Electron-phonon Wannier (EPW) method has confirmed the existence of a robust electron-phonon interaction in 1$T$-RhSeTe, resulting in total EPC constant $λ$ = 2.02, the logarithmic average frequency $ω_{\text{log}}$ = 3.15 meV and $T_c$ = 4.61 K, consistent with experimental measurements and indicative of its classification as a BCS superconductor. The band structure analysis revealed the presence of Dirac-like band crossing points. The topological non-trivial electronic structures of the 1$T$-RhSeTe are confirmed via the evolution of Wannier charge centers (WCCs). Collectively, these distinctive properties underscore 1$T$-RhSeTe as a possible candidate for a topological superconductor, warranting further investigation into its potential implications and applications.

The multi-service centre : A vehicle for social service delivery
Creators: name: Woo, Janet
Publisher: name: University of British Columbia
Year: 2009

description: The multi-service centre (MSC) is a community-focused agency that hosts a variety of social services on one site (e.g., a school, daycare, community centre, library, health clinic, welfare, and community police office can all be clustered together in one location). Some of the general goals, of the MSC are to improve convenience and accessibility to users; provide continuity and holism in service; reduce fragmentation and duplication in the social service system; reduce costs through sharing; and serve as a neighbourhood gathering place. Despite the lack of City policy regarding the MSC, it is nonetheless a prominent model of service delivery in Vancouver. The MSC takes many forms but the most prevalent one is an arrangement whereby a neighbourhood house or community centre is located next to a school. This thesis studies three examples of MSCs in Vancouver and the methodology includes interviews with their directors arid principals, as well as Social Planning staff who have detailed knowledge of these MSCs. Also, a literature review is conducted and substantiates the primary data. The data reveal that such issues as synergy, leadership, efficiency, neighbourhood relevance and scale, facilities and access, and systems impact significantly on the overall performance of the MSC. Further, themes such as balance, courtship, and collaboration serve to guide these features to their full potential. However, the MSC is only one strategy on the continuum of social services. Not to be discounted are other, models, such as the traditional dispersed and the new integrated service delivery approaches. Choice in service delivery is important and each strategy serves to complement and reinforce the other. The policy challenge represented by the need for choice and complementarity in social service delivery resoundingly points to better collaboration in planning systems. Specific policy implications include more integration in planning, more power to municipal planning departments, and increased expansion of the traditional role of the school. The general purpose of this study is to contribute to contemporary planning thought and practice by providing some insight into how social services can be better coordinated and delivered.

For magnetic electrodes one observes marked dependence of S on the degree of their polarization.

description: The paper provides a comprehensive study on Raman spectroscopy versatility as a fast and non destructive tool for the prediction of the mechanical properties of SiC fibers derived from a polymeric precursor (NLM, Hi, Hi-S, SA and Sylramic grades) or produced by CVD (SCS-6 fiber), including in situ analysis in CMCs or MMCs. We show how the results of very simple spectra fitting are correlated with Young's modulus, tensile strength and micro-hardness. The reason why such a correlation exists, the common dependency of Raman signal and mechanical behavior to the micro/nanostructure of ceramics, is discussed.

description: We propose a fully non-perturbative method to compute inelastic lepton-nucleon ($\ell N$) scattering cross sections using lattice QCD. The method is applicable even at low energies, such as the energy region relevant for the recent and future neutrino-nucleon ($νN$) scattering experiments, for which perturbative analysis is invalidated. The basic building block is the forward Compton-scattering amplitude, or the hadronic tensor, computed on a Euclidean lattice. Total cross section is constructed from the hadronic tensor by multiplying a phase space factor and integrating over the energy and momentum of final hadronic states. The energy integral that induces a sum over all possible final states is performed implicitly by promoting the phase space factor to an operator written in terms of the transfer matrix on the lattice. The formalism is imported from that of the inclusive semileptonic B meson decay [P. Gambino, S. Hashimoto, arXiv:2005.13730]. It can be generalized to compute the $\ell N$ scattering cross sections and their moments, as well as the virtual correction to the nuclear $β$-decay. Necessary quark-line contractions for two current insertions corresponding to the Compton amplitude to be computed on the lattice are summarized.

Physical propositions and quantum languages

description: The word \textit{proposition} is used in physics with different meanings, which must be distinguished to avoid interpretational problems. We construct two languages $\mathcal{L}^{\ast}(x)$ and $\mathcal{L}(x)$ with classical set-theoretical semantics which allow us to illustrate those meanings and to show that the non-Boolean lattice of propositions of quantum logic (QL) can be obtained by selecting a subset of \textit{p-testable} propositions within the Boolean lattice of all propositions associated with sentences of $\mathcal{L}(x)$. Yet, the aforesaid semantics is incompatible with the standard interpretation of quantum mechanics (QM) because of known no-go theorems. But if one accepts our criticism of these theorems and the ensuing SR (semantic realism) interpretation of QM, the incompatibility disappears, and the classical and quantum notions of truth can coexist, since they refer to different metalinguistic concepts (\textit{truth} and \textit{verifiability according to QM}, respectively). Moreover one can construct a quantum language $\mathcal{L}_{TQ}(x)$ whose Lindenbaum-Tarski algebra is isomorphic to QL, the sentences of which state (testable) properties of individual samples of physical systems, while standard QL does not bear this interpretation.

description: Real-time track tracking in high energy physics experiments at colliders running at high luminosity is very challenging for trigger systems. To perform pattern-recognition and track fitting in online trigger system, the artificial Retina algorithm has been introduced in the field. Retina can be implemented in the state of the art FPGA devices. Our developments use Retina in an iterative way to identify track for barrel-shape tracker embedded in a high magnetic field and with high track multiplicity. As a benchmark we simulate LHC t-tbar events, with a pile-up of 200 and a GEANT-4 based simulation of a 6-layers barrel tracker detector made of silicon modules. With this sample the performance of the hardware design (resource usage, latency) is evaluated. Both efficiency and purity of the Retina fitting are over 90%. Moreover we have also added a Kalman filter after the Retina fit to improve the resolution on the track parameters. Our simulation results show that the Kalman filter can work well together with the Retina algorithm to find track through t-tbar event and provides high resolutions of the reconstructed parameters.

description: Σκοπός της εν λόγω διπλωματικής εργασίας είναι η εξέταση των κριτηρίων δημοσιονομικής πειθαρχίας κατά το Σύμφωνο Σταθερότητας και Ανάπτυξης. Σημείο εκκίνησης αποτέλεσε η ανάλυση του κανονιστικού πλαισίου που διέπει τη λειτουργία της Οικονομικής και Νομισματικής ‘Ένωσης και ειδικά του Συμφώνου Σταθερότητας και Ανάπτυξης, επί του οποίου προχωρήσαμε σε αξιολογικές επισημάνσεις. Στη συνέχεια εξετάσαμε την εφαρμογή του Συμφώνου Σταθερότητας και Ανάπτυξης στην Ελλάδα, δίδοντας έμφαση στα δύο τελευταία χρόνια (2008-2010) και στην υπαγωγή της χώρας μας στο Μηχανισμό Χρηματοδοτικής Συνδρομής. Σε ιδιαίτερο κεφάλαιο εξετάζεται η διαχείριση της οικονομικής κρίσης από την Ευρωπαϊκή Ένωση και η δημιουργία νέων θεσμών για την αντιμετώπιση των οικονομικών προβλημάτων των χωρών της ευρωζώνης. Ξεχωριστή αναφορά γίνεται στην Στρατηγική «Ευρώπη 2020». Ασχοληθήκαμε επιπλέον με την επικείμενη μεταρρύθμιση του Συμφώνου Σταθερότητας και Ανάπτυξης, παρουσιάζοντας τις προτεινόμενες αλλαγές και προβαίνοντας σε κριτική αποτίμηση των προτάσεων αυτών.
description: The purpose of this thesis is to examine the criteria of fiscal discipline according to the Stability and Growth Pact. The starting point was the analysis of the regulatory framework of the Economic and Monetary Union. We analyzed in particular the Stability and Growth Pact and furthermore we pointed out some evaluation remarks. Afterwards we examined the implementation of the Stability and Growth Pact in Greece, especially with regards to the last two years (2008-2010). In a separate chapter we focused on the way the European Union handled the financial crisis and the creation of new institutions aimed to cope with the economic problems of the euro zone members. Another issue presented in this thesis is the "Europe 2020" strategy. We dealt also with the imminent reform of the Stability and Growth Pact, examining the proposed changes and presenting a critical assessment of these proposals.
Προσέγγιση των επιθέτων με στερητικό α-:

description: Στην παρούσα εργασία εξετάζονται τα στερητικά επίθετα που σχηματίζονται με προθηματοποίηση ονοματικών βάσεων, ουσιαστικών και επιθέτων, καθώς και τα στερητικά επίθετα που παράγονται με βάση ρήμα. Τα επίθετα αναλύονται μορφολογικά και σημασιολογικά και επιχειρείται η διερεύνηση της σημασιολογικής οδηγίας του κατεξοχήν αρνητικού προθήματος της Νέας Ελληνικής, του στερητικού α-, μέσω της μελέτης της συνεισφοράς του στη σημασία των διαφόρων κατηγοριών επιθέτων και της εξακρίβωσης του είδους της άρνησης που εκφράζει. Υποστηρίζεται ότι το πρόθημα έχει ενιαία σημασιολογική οδηγία και αυτή είναι η άρνηση της έννοιας που δηλώνεται με τη βάση της κατασκευασμένης λέξης. Ανάλογα με τη γραμματική και την εννοιακή κατηγορία της βάσης, η σημασία αυτή μπορεί να εξειδικευτεί. Όταν η βάση αντιστοιχεί σε συγκεκριμένα ή αφηρημένα «πράγματα», ανήκει δηλαδή στη γραμματική κατηγορία των ουσιαστικών, η άρνησή της ερμηνεύεται ως στέρηση ή έλλειψη. Όταν η βάση είναι ρήμα, το α- αρνείται τη «γεγονοτικότητα» ή τη δυνατότητα «να γίνει» της ενέργειας που δηλώνεται από το ρήμα. Όταν η βάση είναι επίθετο, το α- αρνείται την ιδιότητα που δηλώνεται από αυτό και το παράγωγο δηλώνει - συνήθως αλλά όχι υποχρεωτικά - την αντίθετη από το πρωτότυπο επίθετο ιδιότητα. Από μορφολογική άποψη, το πρόθημα α-, προστιθέμενο σε ονοματικές και κυρίως ρηματικές βάσεις, προκαλεί σε πολλές περιπτώσεις τη συνεμφάνιση ταξικού σηματοδότη, προκειμένου οι κατασκευασμένες λέξεις να έχουν τη βέλτιστη μορφή σε σχέση με τη γραμματική κατηγορία που ανήκουν ή τη σημασία τους.
description: This study examines the adjectives that can be derived from the attachment of the modern greek negative prefix α- to nouns, adjectives and verbs. The negatively affixed adjectives are analyzed morphologically and semantically and we seek to account for the meanings α- seems to have. It is claimed that the prefix has a core meaning which is the negation of the concept the base denotes. This core meaning is further specified by the grammatical and conceptual category of the base. When the base is a “thing”, concrete or abstract, the derived word has a privative meaning. When the base is a verb, the prefix denotes that what is expressed by the verb can not be done or has not been done yet. When the base is an adjective, α- denotes the negation of the property the base expresses and in the majority of cases base word and derived word are antonyms. From a morphological point of view, the prefix, attached to nominal and verbal bases, causes the co-occurence of an item which has the form of a suffix but not its semantic value, in order for the derived words to have a form consistent with their grammatical category or their meaning.

description: A theoretical framework is developed to study the dynamics of protein folding. The key insight is that the search for the native protein conformation is influenced by the rate r at which external parameters, such as temperature, chemical denaturant or pH, are adjusted to induce folding. A theory based on this insight predicts that (1) proteins with non-funneled energy landscapes can fold reliably to their native state, (2) reliable folding can occur as an equilibrium or out-of-equilibrium process, and (3) reliable folding only occurs when the rate r is below a limiting value, which can be calculated from measurements of the free energy. We test these predictions against numerical simulations of model proteins with a single energy scale.

description: Η παρούσα εργασία έχει ως αντικείμενό της την αξιολόγηση και την μέτρηση της επίδοσης των μαθητών στο μάθημα των θρησκευτικών. Τα τελευταία χρόνια διατυπώθηκαν διάφοροι προβληματισμοί σχετικά με το αν μπορούν οι βαθμοί να προσδώσουν αντικειμενικές πληροφορίες για τους μαθητές και την πρόοδό τους. Σε όλες τις χώρες της ευρώπης αναπτύσσονται και επικρατούν νέες μέθοδοι αξιολόγησης, οι οποίες δίνουν πληροφορίες, όχι μόνο για τις γνώσεις που αποκτά ο μαθητής, αλλά και για την προσωπικότητά του και τη συμμετοχή του στη μάθηση. Στις νέες μεθόδους αξιολόγησης, λοιπόν, συγκαταλέγονται η αξιολόγηση με βάση τον προσωπικό φάκελο του μαθητή, η συστηματική παρατήρηση και η αυτοαξιολόγηση του μαθητή.
description: This study aimed to evaluate and measure the performance of students in the course of the religion. Over the last several years there have been questions about whether the points can give objective information about students and their progress. In all European countries have been developed new methods of evaluation exist, which give information not only on the knowledge acquired by students, but also for their personality and participation in learning. The new assessment methods, therefore, include an assessment based on student's personal file, systematic observation and self-evaluation of the student.
