description: Η λογοκλοπή αποτελεί ίσως το πιο συχνό ακαδημαϊκό παράπτωμα στην τριτοβάθμια εκπαίδευση. Το διαδίκτυο, οι ηλεκτρονικές πηγές και η εύκολη πρόσβαση στην πληροφορία διευκόλυναν την εκδήλωση και την έξαρση αυτού του φαινομένου. Στο πλαίσιο αντιμετώπισης του φαινομένου οι ακαδημαϊκές βιβλιοθήκες προχώρησαν στην αγορά λογισμικών ανίχνευσης πιθανής λογοκλοπής με πιο γνωστό το εργαλείο Turnitin. Στόχος της παρούσας εργασίας είναι να διερευνήσει τη στάση των μελών του διδακτικού και ερευνητικού προσωπικού μεγάλων ακαδημαϊκών ιδρυμάτων όσον αφορά στη λογοκλοπή και στη χρήση του εργαλείου Turnitin. Η έρευνα που θα αναπτυχθεί στο πλαίσιο της εργασίας θα εστιάσει τουλάχιστον σε τρία ιδρύματα: το Αριστοτέλειο Πανεπιστήμιο Θεσσαλονίκης, το Ελληνικό Ανοικτό Πανεπιστήμιο και το Πανεπιστήμιο Δυτικής Αττικής. Τα πρώτα δύο πανεπιστήμια έχουν τη μεγαλύτερη παράδοση στη χρήση εργαλείων λογοκλοπής στην Ελλάδα (πριν το Turnitin χρησιμοποιούσαν το εργαλείο Ephorus). Επίσης, τα δύο αυτά ιδρύματα χρησιμοποιούν εργαλεία λογοκλοπής σε πλήρη ενσωμάτωση με τα περιβάλλοντα ηλεκτρονικής μάθησης. Από την άλλη μεριά, το Πανεπιστήμιο Δυτικής Αττικής τώρα κάνει τα πρώτα βήματά του στη χρήση του Turnitin. Μέσω των ερωτημάτων θα γίνει προσπάθεια να εντοπιστεί η ύπαρξη ή μη πολιτικής των ιδρυμάτων, η στάση και η χρήση από τα μέλη του διδακτικού και ερευνητικού προσωπικού

description: We propose a principled framework that combines adversarial training and provable robustness verification for training certifiably robust neural networks. We formulate the training problem as a joint optimization problem with both empirical and provable robustness objectives and develop a novel gradient-descent technique that can eliminate bias in stochastic multi-gradients. We perform both theoretical analysis on the convergence of the proposed technique and experimental comparison with state-of-the-arts. Results on MNIST and CIFAR-10 show that our method can consistently match or outperform prior approaches for provable l infinity robustness. Notably, we achieve 6.60% verified test error on MNIST at epsilon = 0.3, and 66.57% on CIFAR-10 with epsilon = 8/255.

Theory of magnetotransport in shaped topological insulator nanowires

description: We show that shaped topological insulator (TI) nanowires, i.e. such that their cross-section radius varies along the wire length, can be tuned into a number of different transport regimes when immersed in a homogeneous coaxial magnetic field. This is in contrast with widely studied tubular nanowires with constant cross-section, and is due to magnetic confinement of Dirac surface carriers. In flat 2D systems such a confinement requires non-homogeneous magnetic fields, while for shaped nanowires of standard size homogeneous fields of the order of $B\sim\,1$T are sufficient. We put recent work [Kozlovsky et al., Phys. Rev. Lett. 124, 126804 (2020)] into broader context and extend it to deal with axially symmetric wire geometries with arbitrary radial profile. A dumbbell-shaped TI nanowire is used as a paradigmatic example for transport through a constriction and shown to be tunable into five different transport regimes: (i) conductance steps, (ii) resonant transmission, (iii) current suppression, (iv) Coulomb blockade, and (v) transport through a triple quantum dot. Switching between regimes is achieved by modulating the strength of a coaxial magnetic field and does not require strict axial symmetry of the wire cross-section. As such, it should be observable in TI nanowires fabricated with available experimental techniques.

description: The Group of Ten’s exclusion of either gold revaluation or flexible exchange rates as solutions to the international monetary problem suggests the continued use of reserve media other than gold in order to feed the world pool of international monetary reserves. These two media could theoretically take the form of either commodity reserves or credit reserves. However, current discussions are likely to focus on a better organisation of the latter, which play an increasingly important role in the present monetary system. The present article discusses four issues that arise from this: the overall amounts and stability, the distribution among reserve holders, the distribution among reserve debtors, the institutional framework for implementation.

description: The deformations of flagella are important in the motility of single- and multi-flagellated bacteria. Existing numerical methods have treated flagella as extensible filaments with a large extensional modulus, resulting in a stiff numerical problem and long simulation times. However, flagella are nearly inextensible, so to avoid large extensional stiffness, we introduce inextensible elastic rod models with hydrodynamics treated by a surface distribution of regularized Stokeslets. We benchmark this new model against previously described models of extensible elastic rods with hydrodynamics treated by a centerline distribution of regularized Stokeslets and rotlets, as well as a surface distribution of regularized Stokeslets. We compare the accuracy of the inextensible model with the extensible models and illustrate for which ratios of stretching/bending stiffness (which depend on the diameter of filament) the inextensible model is accurate and more efficient. We show that our inextensible approach can be markedly more efficient than the extensible models for many biological filaments. We also compare the accuracy of the centerline distribution of the Stokeslets and rotlets to the more accurate surface distribution of Stokeslets for modeling fluid-structure interactions of filaments.

description: The article discusses the techniques (or instruments) through which certain monetary policies might be implemented, as opposed to the choice of the policies themselves. In particular, the author is concerned with the implementation of monetary policy in Italy. First, a simple monetary policy model is proposed, designed to illustrate the interrelationships between the behaviour of certain magnitudes and total liquidity changes. Recent monetary trends and policies in Italy are then reviewed. The model is then employed as a tool for programming before some observations on seasonal behaviour are considered. Finally, the outlook for the Italian economy in 1964 is analysed, relating the use of monetary tools to the probable behaviour of the general target variable JEL: E52

Using the renormalization group approach we construct the phase diagram in terms of Rashba coupling, Tomonaga-Luttinger stiffness and backward scattering strength. We identify the parameter regimes with a dynamically generated spin gap and show where the Luttinger liquid prevails. We also discuss the consequences for the operation of the Datta-Das transistor.

Enzymatically polymerized lignosulfonates as binders in biocomposites

Subjects: subject: Lignosulfonates
subject: laccase-mediated polymerization
subject: plasticizers
subject: Biocomposites

description: The aim of this study was to form biocomposites by combining polymerized lignosulfonates plasticized with polyols and impregnated and non-impregnated wood particles. The laccase-mediated polymerization process was examined for changes in viscosity and molecular weight. The resulting polymers were analyzed rheologically and chromatographically. From the resulting polymerization products, biocomposites were produced. These were then subjected to mechanical tests for thickness swelling, bending and tensile strength and compared with a particleboard reference. The results showed that the mechanical properties of the biocomposites did not come close to those of the standard, but that the swelling tests met the European requirements for particleboards in humid conditions. Sorbitol proved to be the best plasticizer in terms of board cohesion. This study highlights the potential to use polymerized lignosulfonates as a sustainable alternative to formaldehyde-based wood adhesives and to generate added value from paper production, which could contribute to a more sustainable and circular economy.

description: Axions may be produced in abundance inside stellar cores and then convert into observable X-rays in the Galactic magnetic fields. We focus on the Quintuplet and Westerlund 1 super star clusters, which host large numbers of hot, young stars including Wolf-Rayet stars; these stars produce axions efficiently through the axion-photon coupling. We use Galactic magnetic field models to calculate the expected X-ray flux locally from axions emitted from these clusters. We then combine the axion model predictions with archival Nuclear Spectroscopic Telescope Array (NuSTAR) data from 10 - 80 keV to search for evidence of axions. We find no significant evidence for axions and constrain the axion-photon coupling $g_{aγγ} \lesssim 3.6 \times 10^{-12}$ GeV$^{-1}$ for masses $m_a \lesssim 5 \times 10^{-11}$ eV at 95\% confidence.

Conditions de l'exploitation des Banques à succursales multiples dans les Pays du Marchè Commun (variations sur un thème de productivitè) (Considerations on the management of banks with numerous branches in the common market countries. ...)

Publisher: name: Moneta e Credito
Year: 2014
Subjects: subject: Banking, productivity, staff, deposits, labour, operations
subject: G21, J24

description: The work is concerned with developing a general concept of productivity in banking. The study finds its origin in the simple observation that if the number of staff in large banks of different countries is divided by total balances or deposits, the quotient will vary from one bank to another, and even more, from the banks in one country to those in others. This criterion implies that the volume of balances or deposits equates banking operations. Thus, for the sake of simplicity, the author takes the ratio of staff/deposits to indicate the productivity of labour. The study is based on the data for the financial year 1959 for the major banks with large numbers of branches in Federal Germany, Belgium, France, Italy and the Netherlands. The methodology used is that of counting the operations characteristic of the main traditional departments of a bank and the number of employees by department, before relating these numbers to the deposits of all maturities of the clientele.

Youth as citizens, youth as workers : an action research approach to community mapping
Creators: name: Amsden, Jacqueline Cynthia
Publisher: name: University of British Columbia
Year: 2011

description: Since its relatively recent inception with the rise of industrialism, youth has been situated as a process of transitioning to labour market participation. Those that fail to secure their roles as consumers/producers, and thus adulthood, are generally framed as deviant, inadequate. The situation for youth is becoming increasingly 'risky' in the current economic and social restructuring occurring under the name of globalization, in which access to stable and adequate employment is now even more deeply stratified according to social, economic, racial, and gendered memberships. One area in which the 'youth' deficit frame plays out is in the federal government's labour market training programs for youth, such as Skills Link, an occupational and employment training program funded by the Government of Canada to help youth with 'barriers' to employment transition to stable and adequate employment. The Environmental Youth Alliance (EYA), a Vancouver-based non-governmental organization, offers a Skills Link program titled the Youth Community Asset Mapping Initiative. In this program, youth learn about themselves and their local environment by creating community maps of Vancouver. In this study, I examine the experience of three youth as they map Vancouver through an action research framework, ultimately asking 'What is the place of youth in downtown Vancouver?' The question that I pose as I explore their project is 'How does community mapping contribute to the development of youth citizenship?' In my analysis, I draw from photos, maps, interviews, and focus group discussions to illustrate the relational, representational, and reflective knowing they engaged in, as well as the job-related skills they developed during the process of mapmaking, such as project management, communication, and teamwork. In doing so, I reveal the potential of mapmaking to foster youth engagement in social, civil and political rights and responsibilities which underpin modern notions of youth citizenship. However, this analysis also reveals a tenuous, inconsistent sense of community and ability to access resources (through gainful employment) that speak to economic pressures of globalization mentioned earlier. Thus, ultimately demonstrating that whilst community mapping holds the potential to engage 'marginalized' youth in citizenship roles, broader priority shifts in governance—which place humanistic goals before economic ones—are needed if we as a society are dedicated to the inclusion of all our young people.

description: A thorough analysis of the stability of the uncoupled Rooth interhemispheric 3-box model of thermohaline circulation (THC) is presented. The model consists of a northern high latitudes box, a tropical box, and a southern high latitudes box, which respectively correspond to the northern, tropical and southern Atlantic ocean. We adopt restoring boundary conditions for the temperature variables and flux boundary conditions for the salinity variables. We study how the strength of THC changes when the system undergoes forcings that are analogous to those of global warming conditions by applying to the equilibrium state perturbations to the moisture and heat fluxes into the three boxes. In each class of experiments, we determine, using suitably de- fined metrics, the boundary dividing the set of forcing scenarios that lead the system to equilibria characterized by a THC pattern similar to the present one, from those that drive the system to equilibria with a reversed THC. Fast increases in the moisture flux into the northern high-latitude box are more effective than slow increases in leading the THC to a breakdown, while the increases of moisture flux into the southern high-latitude box strongly inhibits the breakdown and can prevent it, in the case of slow increases in the Northern Hemisphere. High rates of heat flux increase in the North Hemisphere destabilize the system more effectively than low ones, and increases in the heat fluxes in the Southern Hemisphere tend to stabilize the system.

The origin of the primary singularities of both polarization components of radiation in a wide range of parameters of radiation and the medium is investigated for different values of the parameter characterizing the nonlocality of nonlinear optical response in chiral medium. For each of the values, the visibility diagrams of the primary singularities of both polarization components are plotted depending on the parameters of the medium and radiation, and their asymmetry is found.

Les taux d'intèret en France. (Interest rates in France)

Subjects: subject: France, interest rates, monetary policy, financial system, capital markets
subject: E43, E52

description: As in most countries, the structure of interest rates in France is relatively complex, resulting from conditions in which the direct matching up is effected between the supply of and demand for capital by the various economic agents. However, the intervention of financial institutions as well as of the monetary authorities influence, both directly and indirectly, the way in which interest rates are determined. The present article provides a detailed analysis of interest rate formation in France. The author first examines the basic position and objectives of monetary and economic policy before considering in turn the interest rates on short term and long term markets. It is shown that while interest rates still play a part in adjusting demand to supply on the capital markets, this role is lo longer a dominant one. Moreover, there are still partitions which protect rates of interest whose artificial character impedes the easy and regular matching up of supply and demand as a whole. JEL: E43, E52

description: The European Community Statistical Institute (ECSI) began conducting annual surveys of labour costs in 14 industrial sectors of the Community countries in 1959. The present article illustrates the principal results of the fourth survey that relates to 1962 and is now in course of publication. The analysis is confined to data regarding to labour cost shown as borne by the enterprises, and does not take account of studies made by ECSI of workers’ incomes in various countries. In particular, the author considers the data on the cost of labour in Italy. The data is brought up to date for 1963 and 1964 to show the changes that have taken place in Italy’s position with respect to previous years. While in the surveys tom 1959 and 1960 Italy was shown to have the lowest labour cost among Common Market countries, it now comes in first in the classification and has in almost every case registered a labour cost very near to the highest figure.

description: In recent years important structural changes have occurred in the countries of Western Europe with the secondary and tertiary sectors having expanded far more rapidly than the agriculture sector. Moreover, while the productivity per worker in agriculture has increased, income per worker has lagged behind other sectors and agricultural prices have risen less than non-agricultural products and services. The present work analyses the developments in agriculture that have occurred in Italy, which show particular features and characteristics.

Our proof provides a streamlined way of obtaining this result and allows one to get a better estimate on the norm of the solution. In particular, we were able to improve the estimate found in the recent work of T. Trent. Note that, the solution of the $H^{\infty}$ matrix corona problem in the disk can be easily obtained from the $H^{2}$ corona problem either by factorization, or by the Commutant Lifting Theorem. The $H^{p}$ corona problem in the polydisk was originally solved by K.C. Lin. The solution used Koszul complexes and was rather complicated because one had to consider higher order $\bar{\partial}$-equations. Our proof is more transparent and it improves upon Lin's result in several ways. First, we were able to show that the norm of the solution is independent of the number of generators. Additionally, we illustrate that the norm of the solution grows at most proportionally to the dimension of the polydisk. Our approach is based on one that was originated by M. Andersson. In the disk it essentially depends on Green's Theorem and duality to obtain the estimate. In the polydisk we use Riesz projections to reduce the problem to the disk case.

description: Indonesia is challenged by a shortage of soybean production to meet local demand. The Ministry of Agriculture has developed a strategy to increase soybean production through an integrated crop management (ICM) program, which was implemented through a farmer field school (FFS) approach in 2008. This paper aims to evaluate the performance of FFS-ICM implementation in two of the main areas for soybean production—Grobogan Regency in Central Java Province and West Lombok Regency in West Nusa Tenggara Province. Primary data was collected through in-depth interviews of 120 farmers. The before and after performance of the FFS-ICM program was evaluated using paired sample t-tests. The study found that FFS-ICM has increased soybean productivity significantly both in Grobogan Regency (1,854 kg/ha) and West Lombok Regency (1,492 kg/ha). However, this was less than the optimal productivity, which can reach 2,490 kg/ha in Grobogan Regency and 1,680 kg/ ha in West Lombok Regency, therefore a soybean productivity gap remains. In order to improve the implementation of soybean FFS-ICM, four policy recommendations were suggested: improving the understanding of extension workers and participant farmers on the philosophy of FFS to dispel the perception that FFS-ICM is “an aid distribution” project; intensive assistance and monitoring by field extension workers during the FFS-ICM implementation; ensuring that inputs (especially seeds) are available on time by strengthening breeding institutions at the local level; and strengthening the research and dissemination of new high-yielding varieties that are suited to local agroecosystems and in accordance with market demand.
The nature of the Schoenberg-Chandrasekhar limit

description: We present a comprehensive description of the Schönberg--Chandrasekhar (S--C) transition, which is an acceleration of the stellar evolution from the nuclear to the thermal time scales occurring when the fractional mass of the helium core reaches a critical value, about 0.1. It occurs in the 1.4 to 7 M$_\odot$ mass range due to impossibility of maintaining the thermal equilibrium after the nuclear energy sources in the core disappear. We present the distributions of the hydrogen abundance, the energy generation rate and the temperature for stars crossing that limit. We confirm that a sharp S--C limit is present for strictly isothermal cores, but it is much smoother for real stars. The way the boundary of the core is defined is important for the picture of this transition. With a strict definition of the core as the region where the helium abundance is close to null, it occurs in an extended range of the fractional core mass of roughly 0.03 to 0.11. The cause of that is a gradual core contraction causing a correspondingly gradual loss of the core isothermality with the increasing core mass. On the other hand, when using definitions allowing for some H abundance in the core, the S--C transition is found to be sharper, at the fractional core mass of between about 0.07 and 0.11. Still, it is more a smooth transition than a sharp limit. We have also searched for specific signatures of that transition, and found that it is associated with the stellar radius first decreasing and then increasing again. We have considered whether the S--C limit can be used as a diagnostic constraining the evolutionary status of accreting X-ray binaries, but found such uses unfounded.

description: With the exception of the bifoveate frons and the rather well-developed laterobasal carinae of the pronotum, the members of the inflatus group are very similar in appearance to the members of the laevis group. The male and female genitalia are of the same type, both groups are wingless, and both have partially fused elytra. These two groups, when better known, perhaps should be merged. I treat them as distinct groups here on the basis of the frons and pronotal structure. There are two known species of the inflatus group, both of which are known only from Brazil (Figure 72).

description: This case study investigates food safety practices and costs for seven firms participating in the California Leafy Greens Marketing Agreement (LGMA), formally known as the California Leafy Green Products Handler Marketing Agreement. All firms incorporated additional food safety practices into their food safety plans beyond LGMA requirements, for their own convenience, risk management needs, and/or to satisfy buyer requests. It was difficult to quantify food safety costs; the analysis concentrated on costs for five food safety practices. The cost-share for each practice—the cost of the individual practice divided by the total cost of the five practices—provides insight into the relative cost of food safety practices. The value of the food safety staff (including clerical staff) time in food safety tasks was relatively large—38 percent of the five costs. Another 32 percent of costs was for the food safety time of harvest foremen. Audits accounted for 17 percent, product unharvested due to animal intrusion for 11 percent, and water testing for 2 percent of costs. This analysis can increase understanding of the relative food safety costs for firms under the Food Safety Modernization Act.
Who serves the survey?

Publisher: name: University of British Columbia

description: Who Serves the Survey? is an intimate contemplation on the art history survey. In it, I examine art history's flagship books and courses through their capacity to structure knowledge. Fastening first on what, borrowing from Foucault, might instructively be termed the "art-function" and the "story-function", I cogitate on the capacity of each ("serving under" and "serving up" the survey) to constrict, constrain and contain conceptions of vision, visualization, visual representation and visual comprehension. From there, I delve into the beginnings of the modern art history survey and probe a number of points where it (the survey) both produces and is, in turn, produced by the national, the archival, the financial, the social, the pedagogical, the professional/professorial and (tangentially) the psychological. The last section is analytical and prescriptive in that it poses questions inspired by the advent of visual culture/visual studies as an alternative and an intervention. Key among these, is the vital theoretical and pedagogical query: How might visual material be introduced and studied otherwise? In my judgment, visual cultural studies, growing out of two mutually influential tendencies in Britain: critical art history and cultural studies, provides the best option for reconceiving the study and teaching of visual representations. It has two distinct advantages. Unlike the comparatively rigid methodology of art historical surveys, visual studies refuses to impose a predetermined method or system, choosing instead, to affirm the inquiry process itself by allowing the researcher/bricoleur to track down, cook up and cobble together whatever methodologies fit the task at hand.

Ed il problema di evitare che il paese vada incontro a perdite grevi per tutta la struttura economica e sociale: investimenti in agricoltura completamente perduti e situazioni di dipendenza alimentare dall’estero, che oggi si presentano con dimensioni assai più ampie di quanto comporterebbe una razionale impostazione del problema agricolo.

title: Women engineers in Britain, 1945-2000
Creators: name: Wray, Lesley
Publisher: name: The Open University
Year: 2006

description: This thesis looks at the work of women engineers in the period 1945-2000. Its central focus is the impact gender had on the likelihood of a woman making such a career choice, on the training to become an engineer and on women's lived experiences in the work place. It discusses the impact of the equality legislation and considers the effect that the characterisation of engineering as a male profession had on the numbers of women in engineering and on their treatment.

 The thesis approaches these subjects through a study of the experiences of a group of women engineers. Their life histories are set against the social and economic changes that occurred over the period. It encompasses both women who were engineers at the beginning of the period and those from later generations. The use of oral history allows a rounded picture of the changing experiences of women engineers, their career expectations and the degree of success that they achieved.

 The thesis argues that the history of women engineers has been largely ignored. While their experiences have paralleled that of women in other careers, the continued overwhelming dominance of the profession by men has resulted in a number of assumptions regarding discrimination and harassment that remain unproven. It demonstrates that the social stereotyping of engineering discourages many women from considering the career, thus perpetuating both gender inequality and the myth that women are unwelcome in the career.

description: The present article analyses the significance of the rise in liquid assets in relation to GNP, the related increase in the velocity of money and the declining role of money as a financial asset in the U.S. economy. Moreover, the significance of these developments for monetary policy is considered. The author argues that far from being inimical to the execution of monetary policy, changes in velocity are actually another aspect of the system of checks and balances which characterise the operations of the economic system.

description: New physical effects in the dynamics of an ion confined in an anisotropic two-dimensional Paul trap are reported. The link between the occurrence of such manifestations and the accumulation of geometric phase stemming from the intrinsic or controlled lack of symmetry in the trap is brought to light. The possibility of observing in laboratory these anisotropy-based phenomena is briefly discussed.
