Beyond banking:the potential for credit union participation in community economic development
Creators: name: Delbrouck, Loralee Yanya Athena
Publisher: name: University of British Columbia
Year: 2009

description: Many communities in Canada are experiencing high levels of unemployment, poverty, social breakdown and environmental degradation. In an effort to address these problems, individuals, community groups and all levels of government, are experimenting with an approach to development called community economic development (CED). CED is a grassroots, bottom-up process that focuses on the creation of stable, viable, and equitable local economies. In trying to implement CED strategies, communities and individuals face many obstacles, one of the most significant of which is a lack of capital. Credit unions are locally-owned and controlled co-operative financial institutions with access to significant pools of “local” capital and therefore logical places for communities to turn. This thesis explores ways these institutions can support community economic development in their communities. An examination of the literature and interviews with credit union leaders and CED practitioners, demonstrate that most credit unions are not involved in CED lending. Nor are they particularly committed to CED ideals. This being said, however, the research shows that there are a few credit unions, in both Canada and the United States, that do participate in CED. These credit unions--some with a holistic commitment to CED, others with a partial commitment--support CED in a variety of ways, only one of which is through financing. In addition to providing access to capital, these credit unions fulfil other support functions such as providing technical assistance, building “community” and supporting community infrastructure development. Credit unions that participate in CED are not typical of the credit union movement. Most credit unions do not play a role in supporting community economic development in their communities. The study found that there are significant barriers to their participation in CED, barriers such as a lack of vision, the nature of CED lending, and competition from private financial institutions. In order for credit unions to participate in CED, these barriers must be removed. Ways to reduce some of the barriers are explored in the thesis. The research shows that in order to be able to participate in CED, credit unions require: a committed leadership, staff with community development expertise, new deposits of capital, a means of subsidizing the costs of CED lending, and institutional mechanisms that reduce risk as well as government support. Ways for credit unions to fulfil these needs are outlined. Lastly, research findings are summarized and conclusions are drawn about the role individual credit unions can play in CED. The kinds of initiatives credit union centrals, governments and planners can adopt to support credit unions in this work also explored.

description: This report analyzes Rousseau’s Discourse on the Sciences and Arts and the polemics Rousseau wrote in defense of that work, paying special attention to his rhetoric. In supplementing an interpretation of the First Discourse with Rousseau’s polemics, several of the paradoxes of the work are resolved. I argue that the central paradox of the work, whether Rousseau is for or against science, can be resolved: Rousseau is ultimately in favor of science but highly critical of popularized science. Since virtue is the only sound basis of civil society, and science corrupts virtue, Rousseau speaks out against science. But the life dedicated science is the source of the highest flourishing for those who are capable of it. Hence, he concludes the discourse by praising a certain kind of science that is compatible with virtue. His complex position reveals a keen awareness of the distinction between the few and the many—a distinction of the utmost importance for politics, according to Rousseau. Moreover, I analyze Rousseau’s distinct understanding of civic health and corruption and the causes of corruption. Rousseau does not argue that the sciences and arts are the original or sole causes of corruption; they can only come into being in an already corrupt society. However, they do tend to reinforce corruption and make the return to virtue all but impossible. I conclude with an analysis of what can be done in practice according to Rousseau given his bleak analysis of contemporary politics.
Faked states attack using detector efficiency mismatch on SARG04, phase-time, DPSK, and Ekert protocols

description: In quantum cryptosystems, variations in detector efficiency can be exploited to stage a successful attack. This happens when the efficiencies of Bob's two detectors are different functions of a control parameter accessible to Eve (e.g., timing of the incoming pulses). It has previously been shown that the Bennett-Brassard 1984 (BB84) protocol is vulnerable to this attack. In this paper, we show that several other protocols and encodings may also be vulnerable. We consider a faked states attack in the case of a partial efficiency mismatch on the Scarani-Acin-Ribordy-Gisin 2004 (SARG04) protocol, and derive the quantum bit error rate as a function of detector efficiencies. Additionally, it is shown how faked states can in principle be constructed for quantum cryptosystems that use a phase-time encoding, the differential phase shift keying (DPSK) and the Ekert protocols.

Examples considered here include account of the single-ion anisotropy, structural disorder, frustrations. I introduce main ideas of renormalization and show how it serves the explanation of typical features of criticality in the above systems: softening of the phase transition, changes in the universality class, complicated effective critical behaviour.

description: In the search of a mathematical basis for quantum mechanics, in order to render it self-consistent and rationally understandable, we find that the best approach is to adopt E. Cartan's way for discovering spinors; that is to start from 3-dimensional null vectors and then show how they may be represented by two dimensional spinors. We have now only to go along this path, however in the opposite direction; with these spinors (which are pure) construct bilinearly null vectors: and we find that they naturally generate null vectors of Minkowski momentum space, where Cartan equations defining pure spinors are identical to all equations of motion for massless systems: both the quantum (Weyl's) and the classical ones (Maxwell's), are determined by them. We have then the possibility of a new, purely mathematical, determination of h: the Planck's constant, and thus the possible mathematical starting point for the representation of quantum mechanics.

description: The overarching goal of the present work is to contribute to the understanding of the relations between fetal heart rate (FHR) temporal dynamics and the well-being of the fetus, notably in terms of predicting cardiovascular decompensation (CVD). It makes uses of an established animal model of human labor, where fourteen near-term ovine fetuses subjected to umbilical cord occlusions (UCO) were instrumented to permit regular intermittent measurements of metabolites, pH, and continuous recording of electrocardiogram (ECG) and systemic arterial blood pressure (to identify CVD) during UCO. ECG-derived FHR was digitized at the sampling rate of 1000 Hz and resampled to 4Hz, as used in clinical routine. We focused on four FHR variability features which are tunable to temporal scales of FHR dynamics, robustly computable from FHR sampled at $4$Hz and within short-time sliding windows, hence permitting a time-dependent, or local, analysis of FHR which helps dealing with signal noise. Results show the sensitivity of the proposed features for early detection of CVD, correlation to metabolites and pH, useful for early acidosis detection and the importance of coarse time scales (2.5 to 8 seconds) which are not disturbed by the low FHR sampling rate. Further, we introduce the performance of an individualized self-referencing metric of the distance to healthy state, based on a combination of the four features. We demonstrate that this novel metric, applied to clinically available FHR temporal dynamics alone, accurately predicts the time occurrence of CVD which heralds a clinically significant degradation of the fetal health reserve to tolerate the trial of labor.

description: We present an analysis of all SAX observations of NGC 4151. This source was observed 5 times from 1996 to 2001 with durations ranging from a day to four days. The intrinsic continuum, is absorbed at low energies by a complex system: a cold patchy absorber plus a warm uniform screen photoionized by the central continuum. We find that this dual absorber is the main driver of the observed variability, up to a factor of eight, at 3 keV. In particular the covering fraction of the cold absorber changes on time scales of the order of a day, supporting its association with the Broad Line Region. The column density of the warm gas varies on a longer time scale (months to year). Some of the small amplitude spectral variability above 10 keV can be explained with an intrinsic variation (ΔΓ~0.2).The flux below 1 keV remains constant confirming an extended origin. Its spectrum is reproduced by a combination of a thermal component and a power law with the same slope as the intrinsic continuum but with an intensity a few per cent. A Compton reflection component is significantly detected in 1996 (averaged value of Ω/2π~0.4), with intensity decreasing on time scale of year, and it desappears in 2000 and 2001. The long time scale of variations argues for an association with an optically thick torus at a distance of few light years. An iron line was detected in all spectra. Its energy is consistent with fluorescence by cold iron. We find that the line is variable. Its behaviour is reproduced by a variable component proportional to the level of the reflection flux plus a constant component. The flux of the latter is consistent with the extended line emission observed by Chandra. We conclude that the first component is likely arising from the torus and the second is produced in the extended Narrow Line Region.

description: We present the first results using the Reuven Ramaty High-Energy Solar Spectroscopic Imager, RHESSI, to observe solar X-ray emission not associated with active regions, sunspots or flares (the quiet Sun). Using a newly developed chopping technique (fan-beam modulation) during seven periods of offpointing between June 2005 to October 2006, we obtained upper limits over 3-200 keV for the quietest times when the GOES12 1-8A flux fell below $10^{-8}$ Wm$^{-2}$. These values are smaller than previous limits in the 17-120 keV range and extend them to both lower and higher energies. The limit in 3-6 keV is consistent with a coronal temperature $\leq 6$ MK. For quiet Sun periods when the GOES12 1-8A background flux was between $10^{-8}$ Wm$^{-2}$ and $10^{-7}$ Wm$^{-2}$, the RHESSI 3-6 keV flux correlates to this as a power-law, with an index of $1.08 \pm 0.13$. The power-law correlation for microflares has a steeper index of $1.29 \pm 0.06$. We also discuss the possibility of observing quiet Sun X-rays due to solar axions and use the RHESSI quiet Sun limits to estimate the axion-to-photon coupling constant for two different axion emission scenarios.

description: Abstract

Differentiating between recurrent brain tumors and radiation necrosis remains a significant challenge in neuro-oncology, given the overlapping radiological characteristics of these conditions. Misdiagnosis can lead to incorrect treatment, making the development of accurate diagnostic tools essential. This review focuses on novel biomarkers identified through advanced imaging modalities such as Magnetic Resonance Spectroscopy (MRS), Magnetic Resonance Perfusion (MRP), and Positron Emission Tomography (PET). MRS has demonstrated high diagnostic accuracy, with a choline/NAA ratio of 2.0 or higher predicting tumor recurrence with 85% accuracy. MRP, with relative cerebral blood volume (rCBV) measurements, shows a sensitivity of 82% and specificity of 88% for distinguishing between tumor recurrence and necrosis. PET imaging, using radiopharmaceuticals like [11C]methionine, achieves a sensitivity of 87%, making it superior in detecting metabolic differences between tumor recurrence and necrosis. Hybrid PET/MRI systems further enhance diagnostic precision by combining metabolic and structural data. Emerging biomarkers, such as circulating microRNAs and genomic markers, offer non-invasive options for monitoring tumor recurrence. Future advancements integrating radiomics and artificial intelligence (AI) are expected to improve diagnostic accuracy, making these techniques more reliable and accessible in clinical settings.

description: The purpose of this thesis was to examine the procedure and the mode followed towards the proclamation of a local church as Autocephalous. We examined the interdependence between the rules of secular law, evolving over the centuries, with the Sacred Canons of the Orthodox Church. We have showcased the influence which all the aforementioned legal provisions of both secular and Ecclesiastical - Canon Law, used to and continue to have in shaping the history of the various nations and ethnicities. However, conversely as well, we have examined the effect of specific historical circumstances in the ecclesiastical order and evolution. We found that, over time, the provision of a status of an ecclesiastical autocephaly in an ethnic group and the secession from the mother – Church was inseparably connected, apart from other, with the acquisition of national independence and self-government and the severance from the superior and broader state authority. We've mentioned the practice established by the Ecumenical Councils and reported in detail the process by which the local Orthodox Churches were proclaimed Autocephalous during the 19th and 20th century, especially the Churches of Russia, Bulgaria, Serbia and Czech-Slovakia. Finally, we have dealt in detail with the evolution of inter-Orthodox dialogue during the recent decades, concerning the issue of the procedure of awarding the autocephalous status in an ecclesiastical province.

description: Abstract

Background: Differentiating between recurrent brain tumors and radiation necrosis (RN) remains a significant challenge in neuro-oncology due to overlapping clinical and imaging features. Accurate diagnosis is crucial for guiding treatment strategies and improving patient outcomes.

Main Body: Recent advances in imaging techniques have shown promise in enhancing diagnostic accuracy for distinguishing between recurrent tumors and RN. Perfusion-weighted imaging (PWI), diffusion-weighted imaging (DWI), and magnetic resonance spectroscopy (MRS) are among the modalities being studied. Magnetic resonance spectroscopy, for example, has demonstrated a sensitivity of approximately 80% and a specificity of 78% in differentiating these conditions. Additionally, positron emission tomography (PET) with new tracers, such as fluorine-18 labeled DOPA (18F-FDOPA) and fluorine-18 labeled fluciclovine (18F-Fluciclovine), offers diagnostic accuracies ranging from 75% to 95%. Beyond imaging, molecular biomarkers, such as circulating tumor DNA (ctDNA) and microRNAs, are being explored for their potential to improve non-invasive diagnostic methods.

Conclusion: This review synthesizes recent advancements in imaging technologies and molecular biomarkers, highlighting their potential role in refining clinical decision-making and enhancing patient outcomes in the management of brain tumors and radiation necrosis.

description: Using a Fourier approach we offer a general solution to calculations of slip velocity within the circuit description of the electro-hydrodynamics in a binary electrolyte confined by a plane surface with a modulated surface potential. We consider the case with a spatially constant intrinsic surface capacitance where the net flow rate is in general zero while harmonic rolls as well as time-averaged vortex-like components may exist depending on the spatial symmetry and extension of the surface potential. In general the system displays a resonance behavior at a frequency corresponding to the inverse RC time of the system. Different surface potentials share the common feature that the resonance frequency is inversely proportional to the characteristic length scale of the surface potential. For the asymptotic frequency dependence above resonance we find a 1/omega^2 power law for surface potentials with either an even or an odd symmetry. Below resonance we also find a power law omega^alpha with alpha being positive and dependent of the properties of the surface potential. Comparing a tanh potential and a sech potential we qualitatively find the same slip velocity, but for the below-resonance frequency response the two potentials display different power law asymptotics with alpha=1 and alpha~2, respectively.

description: Nitrogen oxides, nitric oxide (NO) and nitrogen dioxide (NO2) play a significant role in troposphere’s chemistry. They regulate the photochemical production of the ozone, as well as the copiousness of the hydroxyl’s (OH) root which is the main oxidative means in the atmosphere. The biological soil emissions of NOx is an important source of the tropospheric (NOx emissions from the soil are responsible for 16% of their total global concentration in the troposphere). Their importance is even greater in agricultural areas where their shareholdings to the total emissions of NOx are pointedly greater Through the present dissertation, the author attempted to develop an empirical model to determine the nitrogen oxide emission levels from the soils. Specifically emissions parameterized using empirical relationships / equations between the type of cover / land use and soil temperature.

description: The aim of the present thesis was the study of socialization of students in a multicultural school environment. We studied the different models that developed over the years in different countries, the European policy and the Greek institutional framework about the socialization and education of minority groups through the educational system. Then, we analyzed the multicultural school as a social environment emphasizing at the social relationships that develop in such an environment between students with different backgrounds as in the relationships between teachers and students. In the research part of the thesis, we examined variations between students at different aspects of school socialization and the variables-factors which are responsible for these variations, as and the quality of social relationships between Greek and foreign students in school. At last, we present the basic conclusions which resulted from research and we try to link them with the theoretical background of the thesis.

description: Based on the description of unstable $K_{L,S}$ particles in quantum field theory (QFT), we compute the time-dependent probabilities for transitions between asymptotic states in $τ^{\pm} \to [π^+π^-]_Kπ^{\pm}ν$ decays, where the pair $[π^+π^-]_K$ is the product of (intermediate state) neutral kaon decays. Then we propose a definition of $τ$ decays into $K_L$ and $K_S$ states, which reflects into the cancellation between their CP rate asymmetries, thus solving in a natural way the paradox pointed out previously in litterature. Since our definition of $K_{L,S}$ final states in $τ$ decays is motivated on experimental grounds, our predictions for the integrated CP rate asymmetries can be tested in a dedicated experiment.

My research aims at profiling the contribution by Italian, French and Greek literati to the moulding of national identity, according to the model B.A. has brought up in “Imagined Communities”.
As for the corpus, following Edward Said’s “Orientalism”, I have selected works of 19th century travel literature belonging to Philhellenism and Oriental Exoticism. The purpose of my essay is to highlight how these two movements, both rooted in Romanticism, have contributed to create a western identity for Athens and an oriental one for Istanbul, without taking into account the fact the two cities shared common Byzantine – Ottoman roots or, better, that they both geo-politically belonged to the Intermediate Region  as identified by Dimitri Kitsikis.

Στόχος της παρούσας έρευνας είναι να διερευνήσει εκείνους τους παράγοντες, οι οποίοι επηρεάζουν το Κόστος Μεταποίησης της Βιομηχανικής Τομάτας. Η συγκεκριμένη γεωργική βιομηχανία που εξετάζεται είναι η Νομικός Δ. Α.Β.Ε.Κ, η οποία βρίσκεται 250 χλμ βορειοδυτικά των Αθηνών, έχει ημερησία δυναμικότητα επεξεργασία νωπής τομάτας που ξεπερνά 3.500 τόνους ανά 24 ώρες και μπορεί να επεξεργαστεί πάνω από 180.000 τόνους τομάτας ανά σαιζόν. Τα τελικά προϊόντα της Νομικός Δ. Α.Β.Ε.Κ είναι τοματοπολτός, χυμός τομάτας, Pizza Sauce, Ψιλοκομμένη αποφλοιωμένη τομάτα (ΚΟΝΚΑΣΕ). Στην παρούσα εργασία πραγματοποιήθηκε εκτίμηση για το κόστος παραγωγής του τοματοπολτού και του κονκασέ, χρησιμοποιώντας δύο οικονομετρικά υποδείγματα πολλαπλής παλινδρόμησης, όπου εφαρμόστηκε και στα δύο η μέθοδος ελαχίστων τετραγώνων (Ordinary Least Squares, OLS) με τη χρήση του οικονομετρικού πακέτου Gretl, έκδοση 1.9.14. Τα αποτελέσματα της έρευνας έδειξαν ότι η μεταβλητή που επηρεάζει σε μεγάλο βαθμό το κόστος παραγωγής του τοματοπολτού και του κονκασέ είναι η αξία της πρώτης ύλης, ένω αυτές με την μικρότερη επίδραση είναι ο βαθμός αξιοποίησης της δυναμικότητας του εργοστασίου και η διάρκεια λειτουργίας του εργοστασίου, αντίστοιχα.
description: Αγγλική Περίληψη The branch of tomato products constitute one of the most important branches of Greek agricultural production, as ranks Greece at a high international reputation based on its production and presents a strong export orientation. The aim of this research is to investigate those factors that affect the cost of Processing Tomato Industry. This agricultural industry that is considered is the Nomikos D. A.B.E.K, located 250 km northwest of Athens, has a daily processing capacity of fresh tomatoes exceeding 3,500 tons per 24 hours and can process over 180,000 tonnes of tomatoes per season. The final products of Nomikos D. A.B.E.K, is tomato paste, tomato juice, Pizza Sauce, Chopped peeled tomatoes (chopped). In the present study the estimation was done for the cost of production of tomato paste and chopped, using two econometric models of multiple regression, which was applied to both the method of least squares (Ordinary Least Squares, OLS) using the econometric package Gretl, version 1.9.14. The results of the research showed that the variable that greatly affects the cost of production tomato paste and chopped is the value of the raw material, while those with the least impact are the degree of capacity utilization of the plant and the duration operation of the plant, respectively.
A technique for the study of factors influencing sodium excretion in the rabbit and its use in examining the role of cephalic sodium concentration in the control of renal sodium excretion

description: The regulation of overall body fluid balance as well as fluid sodium concentration and osmolality involves a complex and interrelated sequence of similar receptor and effector mechanisms. In a recent study in conscious dogs, intracarotid infusions of hypertonic saline were performed concurrent with a jugular vein infusion of water at a rate such that only the areas of the brain supplied by the carotid arteries experienced an increase in plasma sodium concentration (Enimeluth et al., 1992). The results of these infusions were then compared to the effects of an identical salt and water load infused as isotonic saline at the same rate into the carotid arteries and jugular vein. It was concluded from these studies that a mechanism regulating sodium excretion in the distribution of the carotid arteries exists in the conscious dog, that the efferent pathway of this mechanism likely involves the release of urodilatin (a natriuretic peptide), and that this occurs in response to changes in osmolality smaller than those required to stimulate the release of vasopressin. In order to further examine these conclusions, we used similar intracarotid infusions of hypertonic and isotonic saline in an anaesthetized rabbit preparation. The preparation used in these experiments was developed so that renal perfusion pressure could be controlled without interrupting renal blood flow at any time during the surgical procedure. This preparation was examined with respect to the state of hydration of the animals, renal function and renal nerve function,, all of which were determined to be normal. Results of experiments done using this preparation do not support the concept of a specific mechanism regulating sodium excretion in the distribution of the carotid arteries that acts independently of renal perfusion pressure. The intracarotid infusion of hypertonic saline did not cause a greater increase in sodium excretion or a greater decrease in renal vascular resistance than the intracarotid infusion of isotonic saline. Immunoreactive atrial natriuretic peptides do not appear to play a role in mediating sodium excretion in this study and, the release of vasopressin and an increase in sodium excretion appeared to occur in response to the same degree of osmotic change.

description: Σκοπός της παρούσας μελέτης, είναι η διερεύνηση των υδατικών πόρων στη λεκάνη του Δήμου Μουδανιών της Χαλκιδικής. Έπειτα από κατάλληλη συλλογή υπαρχουσών μετρήσεων, ταξινόμηση διαθέσιμων δεδομένων, καθώς και επεξεργασία αυτών, προχωρήσαμε στη δημιουργία ενός υδρολογικού μοντέλου, το οποίο μπορεί να χρησιμοποιηθεί για την εκτίμηση όχι μόνο των υπόγειων, αλλά και των επιφανειακών υδατικών πόρων. Το μοντέλο δημιουργήθηκε και επεξεργάστηκε με τη χρήση του υδρολογικού μοντέλου MIKE SHE, το οποίο έχει κατασκευαστεί από το Δανέζικο Υδρολογικό Ινστιτούτο Νερού και Περιβάλλοντος (Danish Hydrology Institute Water & Environment, DHI). Δεδομένου ότι η μελέτη κατευθύνθηκε προς την ενδελεχή εξέταση της υδρολογικής λεκάνης των Μουδανιών, το MIKE SHE αποτέλεσε το κατάλληλο μοντέλο για την εξαγωγή ασφαλών συμπερασμάτων. Για την αντιπροσωπευτικότερη και ακριβέστερη επίτευξη της προσομοίωσης, χρησιμοποιήθηκαν δεδομένα από προηγούμενες μελέτες που έχουν λάβει χώρα στην υπό μελέτη περιοχή. Τα δεδομένα αυτά, σε συνδυασμό με την πολυπλοκότητα των μεθόδων που χρησιμοποιεί το πρόγραμμα, κατέστησαν τα δημιουργούμενο μοντέλο ικανό να προσομοιώσει επαρκώς τις υδραυλικές ιδιότητες της περιοχής, εκπροσωπώντας πλήρως όλα τα υδρολογικά της στοιχεία.
description: The purpose of this study is to explore the water resources of the Moudania basin, in the southwest of Chalkidiki, Greece. After properly collecting any existing measurements, classifying the available data and processing them, we managed to create a hydrological model. The created model can be used to estimate, not only groundwater, but also surface water resources. The model was created and edited with the use of the hydrological model MIKE SHE, which is manufactured by the Danish Hydrological Institute of Water and Environment (DHI). Since the study was directed to a thorough examination of the catchment basin of Moudania, the MIKE SHE was the appropriate model, in order to draw firm conclusions. To achieve a representative and accurate simulation, we used data from previous studies that have taken place in the study area. The aforementioned data were used in combination with the complexity of the methods that are embedded in the program. Thus, the generated model fully simulated the hydraulic properties of the region.

description: Η διερεύνηση του πεδίου εκπαίδευσης ενηλίκων δεν είναι δυνατή χωρίς την εξέταση των ιστορικών συνθηκών και προϋποθέσεων κάτω από τις οποίες αυτή αναπτύχθηκε και εφαρμόστηκε. Η σύγχρονη ιστορική έρευνα στην εκπαίδευση ενηλίκων είναι σε θέση να συμβάλλει στον εντοπισμό εκείνων των πολιτικό- ιδεολογικών και κοινωνικο-οικονομικών συνθηκών και σκοπιμοτήτων που διαμορφώθηκαν στην πορεία της εξέλιξής της με αποτέλεσμα τη διαφοροποίηση των στόχων και στρατηγικών της. Παράλληλα η διαχείριση του ελεύθερου χρόνου του σύγχρονου ενήλικου συνδέεται στενά στις μέρες μας με τις δομές εκπαίδευσης Ενήλικων. Στην εργασία αυτή μελετάμε τις εκπαιδευτικές δραστηριότητες τα προγράμματα και στρατηγικές των σημαντικότερων δημόσιων φορέων εκπαίδευσης ενηλίκων στον Νομό Θεσσαλονίκης την χρονική περίοδο 1980 έως και τις μέρες μας, καθώς και τη συμβολή της δράσης τους τόσο στην τοπική ανάπτυξη όσο και στην ποιοτική διαχείριση του χρόνου του ενήλικου εκπαιδευόμενου.
description: ABSTRACT The investigation in the field of adult education should be related to the historical and political circumstances which apply to its growth and development. The contemporary historical research in the field of adult education is contributing to the pinpoint of the political-ideological and socio-economic factors and strategies that were formed through historical time, redirecting the aims and practical issues in adult education. Alongside the management of modern adult’s free time is closely nowadays to the structures of Adult Education. This study focuses on the educational activities and strategies of both most important public institutions of adult education in the Prefecture of Thessaloniki between 1980 to the present day as well the contribution of their action in the local development and quality management in time of the adult learner.

description: Οι θεωρίες της λογοτεχνίας στάθηκαν σημαντικές στην εξέταση του έργου του Κ. Π. Καβάφη. Στην εργασία «Ο Κ. Π. Καβάφης και η μεταποικιακή θεωρία» δίνεται η έμφαση στη μεταποικιακή θεωρία και στην ερμηνευτική προσέγγιση του καβαφικού έργου, η οποία βασίζεται στις αρχές αυτής της θεωρίας. Ο όρος "μεταποικιακός" σχετίζεται με πολιτισμούς οι οποίοι έχουν επηρεαστεί από τον καθεστώτα του ιμπεριαλισμού και από το αποικιακό κίνημα. Η μεταποικιακή θεωρία εξετάζει διάφορα φαινόμενα τα οποία σχετίζονται με την αποικιοκρατική πρακτική και, όταν πρόκειται για τη λογοτεχνία, λογοτεχνικά κείμενα τα οποία προέρχονται από τις χώρες της περιφέρειας και από τις χώρες οι οποίες κάποτε ήταν αποικίες των μεγάλων και ισχυρών χωρών. Στην αναζήτηση των μεταποικιακών γνωρισμάτων στην καβαφική ποίηση αυτή η εργασία επικεντρώνεται στην εποχή του ποιητή, στον τόπο όπου ζούσε, στις ιστορικές συνθήκες, καθώς και στα θέματα τα οποία επικρατούν στην ποίησή του. Το έργο του Κ. Π. Καβάφη προσφέρεται για την εφαρμογή της μεταποικιακής θεωρίας επειδή στα κείμενά του αναγνωρίζονται ζητήματα τα οποία είναι σημαντικά για τη μεταποικιακή θεωρία: πολιτισμικό ζήτημα (πολιτισμική ταυτότητα και η έννοια των πολιτισμένων), ζήτημα του ιμπεριαλισμού και της αποικιοκρατίας, καθώς και το ενδιαφέρον για το ιστορικό γίγνεσθαι.
description: Theories of literature have been important in examining the work of C. P. Cavafy. In the paper "C. P. Cavafy and Postcolonial Theory" the emphasis is given on postcolonial theory and on an interpretative approach of Cavafy's work that is based on the principles of this theory. The term "postcolonial" is related to the cultures that had been affected by the regime of imperialism and by the colonial movement. The postcolonial theory examines various phenomena associated with the practice of colonialism and, when it comes to literature, it examines literary texts that come from peripheral countries and countries that had been colonies of large and powerful countries. Examining the postcolonial characteristics in Cavafy's poetry this paper lays stress οn the era of the poet, on the place where he lived, on historical conditions as well as on the themes prevalent in in his poetry. The postcolonial theory can be applied on work of C. P. Cavafy because the matters that are important for postcolonial theory are also identified in his writings: cultural matter (cultural identity and signification of «civilised» people), matter of imperialism and colonialism, as well as an interest in the historical genesis.

description: Σκοπός της εργασίας είναι η μελέτη της προσρόφησης διμερών, ανοιχτών και κλειστών τριμερών και γενικότερα r-μερών από διαλύματα πάνω σε ενεργειακά ομογενείς επιφάνειες. Η στιβάδα προσρόφησης θεωρείται ότι είναι δισδιάστατη, με εξαγωνική πλεγματική δομή και σχηματίζεται επάνω σε μία ενεργειακά ομογενή και επίπεδη επιφάνεια. Η προσρόφηση λαμβάνει χώρα από αραιά διαλύματα, δηλαδή διαλύματα στα οποία η προσροφούμενη ουσία έχει πολύ μικρή συγκέντρωση, και τα οποία θεωρούμε ότι συμπεριφέρονται ιδανικά. Η μελέτη έγινε με βάση τις θεωρητικές μελέτες του Guggenheim για τις ιδιότητες μιγμάτων με πλεγματική δομή, για τα οποία έχει αναπτύξει πληθώρα σχέσεων για την ελεύθερη ενέργεια ΔF και από αυτές τις σχέσεις παρήχθησαν οι αντίστοιχες εξισώσεις των χημικών δυναμικών, από τις οποίες προoέκυψαν οι ισόθερμες προσρόφησης των προσροφημένων ειδών. Κατόπιν αυτού, θα πραγματοποιήθηκε μία πρώτη προσπάθεια υπολογισμού των ισόθερμων προσρόφησης των προσροφημένων ειδών μέσω της μεθόδου Monte-Carlo.
description: The aim of the present thesis was the study of the dimmers, open and closed trimmers and general r-mers adsorption from solutions on energetically homogeneous surfaces. The adsorption layer is considered as two dimensioned, with hexagonal grid structure and it is formed on energetically homogeneous and flat surface. The adsorption is taken place in dilute solutions, in which the solute has low concentration. The study was based on Guggenheim’s mixture properties with grid structure theoretical studies. He has developed a large amount of free energy mathematical relations. The chemical potential is determined by the free energy and finally the adsorption isotherms are determined by the chemical potential. At the end, it was carried out a first trial to compute and simulate adsorption isotherms of adsorbed molecules through Monte-Carlo simulations.
