description: Πρωτεύων σκοπός της εργασίας είναι η ανίχνευση του ρόλου του μαθήματος των γαλλικών και οι επιδιώξεις της διδασκαλίας του στα ελληνικά σχολέια της μέσης εκπαίδευσης του ελληνικού κράτους και του έξω ελληνισμού, κατά τον 19ο αιώνα. Οι επιμέρους στόχοι συνδέονται με την οργάνωση του μαθήματος, τη μεθόδευση διδασκαλίας, το διδακτικό προσωπικό και το περιεχόμενο των γαλλικών διδακτικών βιβλίων, των <>. Ο ρόλος του μαθήματος των γαλλικών είναι ο ίδιος με αυτόν του μαθήματος των αρχαίων ελληνικών και η διδασκαλία των δύο μαθημάτων βαίνει παράλληλα τόσο ως προς τη μεθοδολογία όσο και ως προς τους επιδιωκόμενους στόχους. Σκοπός δηλαδή του μαθήματος των γαλλικών είναι να συμβάλλει στην επίτευξη του πρωτεύοντα σκοπού της μέσης εκπαίδευσης δηλ. τη διάπλαση χαρακτήρων και τη δημιουργία "πολιτών αγαθών και εναρέτων" μέσα από τα κείμενα των διδακτικών βιβλίων. Οι "γαλλικές χρηστομάθειες" δηλ. γίνονται το μέσο για την καλλιέργεια της ηθικής, πολιτικής, εθνικής και θρησκευτικής συνείδησης των μαθητών. Οι παράλληλοι στόχοι της διδασκαλίας σχετίζονται με τη συνέχιση των σπουδών στο πανεπιστήμιο, την επιτυχία στην εργασία και την κοινωνικοποίηση του νέου ανάλογα με το φύλο
description: The primary objective of this research work is the identification of the role and the aim of french language courses in the greek schools of secondary education of both the greek state and the ottoman empire during the 19th century. Secondary objectives include identification of course organisation and content, teaching methodology, faculty and content of french books, the "french chestomathies". The role of french courses is the same with that of ancient greek language courses and the teaching of the two courses goes in parallel in what concerns both the methodology and the objectives sought. Therefore, the scope of france language courses is to promote(contribute in) the primary objective of the secondary education, which is character formation and the creation of "decent and proper citizens", through text books. This means that "french chestomathies" become the means for creating moral, political, national and religious consciousness to the pupils. Collateral objectives of the teaching of french language courses relate to continuing education in the university success abd gender-related socialisation of juveniles

description: Die Europäische Union hat aus ehemals verfeindeten Ländern, die sich in zwei Weltkriegen bekämpften, einen Staatenverbund aus befreundeten Ländern gemacht. Schon lange vor den ersten Schritten in diese Richtung fand in der Zwischenkriegszeit der 1920er-Jahre vor allem in Deutschland und Österreich eine Debatte über die Zukunft Europas statt, an der sich auch zahlreiche Schriftsteller mit fiktionalen, essayistischen und weltanschauungsliterarischen Texten beteiligten. Die damaligen Vorstellungen unterschieden sich allerdings oft deutlich von den heutigen liberaldemokratischen Konzepten eines politisch und wirtschaftlich integrierten Kontinents: Neben progressiven und liberalen Ideen gab es auch Europa- Entwürfe, die mit einer ausgeprägten Freund-Feind-Matrix antiliberale Gegenordnungen imaginierten. In einem gemeinsamen Forschungsprojekt mit Kolleginnen und Kollegen aus Frankreich und Italien beschäftigen sich Heidelberger Literaturwissenschaftlerinnen und -wissenschaftler mit diesen bisher weitgehend unbeachteten liberalismuskritischen Europa-Debatten im frühen 20. Jahrhundert.

Aber können Staaten überhaupt Freunde sein – oder existieren in der Politik nicht vielmehr nur Interessen? Ein Blick in die deutsch-amerikanische Geschichte zeigt, dass Beziehungen zwischen Staaten nicht für die Ewigkeit gemacht sind – und dass Deutschland und die USA gerade wieder ihr Verhältnis grundlegend neu definieren müssen.

description: Freund oder Feind? Die bekannt gewordenen Fälle von Polizeigewalt zeigen, dass nicht alle Polizeikräfte immer und für jeden „Freund und Helfer“ sind. Doch die Frage „Freund oder Feind?“ stellt sich umgekehrt auch Polizistin- nen und Polizisten im Einsatz – und muss dann häufig in Sekundenbruchteilen beantwortet werden: Geht vom Gegenüber eine unmittelbare Gefahr aus, so dass geschossen werden muss? Auch in lebensbedrohlichen Einsätzen müssen Polizeikräfte in der Lage sein, ihre Emotionen zu regulieren, angemessen zu reagieren und unangebrachte Gewalt zu unterlassen. In einem interdisziplinären EU-Forschungsprojekt bringen Sportwissenschaftlerinnen und -wissenschaftler der Universität ­Heidelberg sportpsychologische Erkenntnisse zu Leistung unter Stress ein, um Polizeikräfte in virtuellen Stresstrainings auf solche Einsätze vorzubereiten.

General theory of robustness against disorder in multi-band superconductors

description: We investigate the influence of general forms of disorder on the robustness of superconductivity in multiband materials. Specifically, we consider a general two-band system where the bands arise from an orbital degree of freedom of the electrons. Within the Born approximation, we show that the interplay of the spin-orbital structure of the normal-state Hamiltonian, disorder scattering, and superconducting pairing potentials can lead to significant deviations from the expected robustness of the superconductivity. This can be conveniently formulated in terms of the so-called "superconducting fitness". In particular, we verify a key role for unconventional $s$-wave states, permitted by the spin-orbital structure and which may pair electrons that are not time-reversed partners. To exemplify the role of Fermi surface topology and spin-orbital texture, we apply our formalism to the candidate topological superconductor Cu$_x$Bi$_2$Se$_3$, for which only a single band crosses the Fermi energy, as well as models of the iron pnictides, which possess multiple Fermi pockets.

description: We use the Millennium Galaxy Catalogue (MGC) to study the effect of compact galaxies on the local field galaxy luminosity function. Here we observationally define as `compact' galaxies that are too small to be reliably distinguished from stars using a standard star-galaxy separation technique. In particular, we estimate the fraction of galaxies that are misclassified as stars due to their compactness. We have spectroscopically identified all objects to B_MGC = 20 mag in a 1.14 deg^2 sub-region of the MGC, regardless of morphology. From these data we develop a model of the high surface brightness incompleteness and estimate that ~1 per cent of galaxies with B_MGC < 20 mag are misclassified as stars, with an upper limit of 2.3 per cent at 95 per cent confidence. However, since the missing galaxies are preferentially sub-L* their effect on the faint end of the luminosity function is substantially amplified: we find that they contribute ~6 per cent to the total luminosity function in the range -17 < M_B < -14 mag, which raises the faint end slope alpha by 0.03^{+0.02}_{-0.01}. Their contribution to the total B-band luminosity density is ~2 per cent. Roughly half of the missing galaxies have already been recovered through spectroscopy of morphologically stellar targets selected mainly by colour. We find that the missing galaxies mostly consist of intrinsically small, blue, star-forming, sub-L* objects. In combination with the recent results of Driver et al. (2005) we have now demonstrated that the MGC is free from both high and low surface brightness selection bias for giant galaxies (M_B

description: Abstract:
This paper introduces basic concepts of chaos theory into the world of big data and real-time big data analysis. It concentrates on demonstrating how chaos theory can be applied to analysing big data, what elements must be present, and what the possible outcomes can be. Although chaos theory contains a few set rules, the paper concentrates on the meaning and importance of the butterfly effect in finding patterns and trends within big data analysis. It should be noted that, although many aspects of the application of chaos theory to big data analytics are largely theoretical or in the infancy of deployment, almost all big data analysing systems active today make use of the essential components contained within chaos theory.

description: Wenn Paare sich trennen, kann im Extremfall aus dem früheren Freund ein Feind werden: Ein Stalker, der oder die sich mit der Trennung nicht abfinden will und den Expartner penetrant belästigt, bedroht und terrorisiert – und im schlimmsten Fall sogar tötet. Bei mehr als der Hälfte aller Stalking-Fälle handelt es sich um Expartner-Stalking, doch es gibt auch andere Motive für derartige Nachstellungen. Grundsätzlich kann jeder Mensch zum Stalking-Opfer werden – für Frauen ist die Gefahr aber wesentlich größer als für Männer, die umgekehrt rund 80 Prozent der Täter stellen. Ein Fall für die forensische Psychiatrie werden jedoch die wenigsten Stalker: Noch nicht einmal zehn Prozent der Täter leiden unter schwerwiegenden psychischen Störungen.

description: This thesis studies the ideological reactions, the linguistic prejudices and the linguistic-iconic stereotypes, in other words, the ideology, related to the thessalian dialect, in two language groups : non thessalian informers(Athens, Thessaloniki) and thessalian informers(Larissa, Trikala, Karditsa). The aim of this study is to identify the place of the thessalian dialect in the context of the neo-hellenic dialectology from a sociolinguistic point of view, and to examine its social practices through a semiotic approach of the language ideology. The methodology of the sociolinguistic research is based on recorded interviews based on questionnairies and shared observation. The answers of the informers were analysed using the statistic program SPSS 10, on the level of frequencies and cross tabulations, searching for statistically significant tables. The sociolinguistic results for the two groups derive from this analysis

A poco più di trent'anni di distanza questo testo ci appare per molti versi come un documento postumo, manifesto di un progetto – il postmodernismo – già esauritosi, riproposto «quando ormai la discussione si volge piuttosto altrove, alla consunzione di questo termine e, in definitiva, all'epilogo di una fase» (ibid.).

description: A gaseous Bose-Einstein condensate (BEC) offers an ideal testing ground for studying symmetry breaking, because a trapped BEC system is in a mesoscopic regime, and situations exist under which symmetry breaking may or may not occur. Investigating this problem can explain why mean-field theories have been so successful in elucidating gaseous BEC systems and when many-body effects play a significant role. We substantiate these ideas in four distinct situations: namely, soliton formation in attractive BECs, vortex nucleation in rotating BECs, spontaneous magnetization in spinor BECs, and spin texture formation in dipolar BECs.

Visioni proibite. I film vietati dalla censura italiana (1947-1968)

description: Nell’episodio “Le tentazioni del dottor Antonio” (Dir. Federico Fellini, Italia-Francia, 1962) di Boccaccio ’70, Fellini tratteggia i caratteri prototipici del censore. Fervido anticomunista, cattolico, piccolo borghese e patologicamente sessuofobo, Antonio Mazzuolo, interpretato da Peppino De Filippo, rappresenta non solo il perfetto compimento della vendetta del regista nei confronti dell’ex ministro Umberto Tupini, ma soprattutto l’incarnazione cinematografica di quel nugolo di figure anonime incaricate (o auto-incaricatesi) di vigilare sulla morale pubblica per conto dello stato italiano.Il volume di Curti e Di Rocco, integrato nel gennaio del 2015 dalla seconda parte del progetto, dedicata alle “visioni proibite” dal 1969 a oggi, mira a restituire i fasci di relazioni che si stabiliscono tra leggi, prassi ministeriali e i “dottor Antonio”: anche se la ricchissima parte dedicata alla schedatura dei film costituisce un imprescindibile punto di partenza per chiunque desideri approfondire l’argomento, l’obiettivo non è l’analisi di specifici casi, ma la descrizione di ciò che può essere definito come “ambiente censorio”.

description: A mixture of light and heavy spin-polarized fermionic atoms in an optical lattice is considered. Tunneling of the heavy atoms is neglected such that they are only subject to thermal fluctuations. This results in a complex interplay between light and heavy atoms caused by quantum tunneling of the light atoms. The distribution of the heavy atoms is studied. It can be described by an Ising-like distribution with a first-order transition from homogeneous to staggered order. The latter is caused by an effective nonlocal interaction due to quantum tunneling of the light atoms. A second-order transition is also possible between an ordered and a disordered phase of the heavy atoms.

description: The novel coronavirus disease (COVID-19) pneumonia has posed a great threat to the world recent months by causing many deaths and enormous economic damage worldwide. The first case of COVID-19 in Morocco was reported on 2 March 2020, and the number of reported cases has increased day by day. In this work, we extend the well-known SIR compartmental model to deterministic and stochastic time-delayed models in order to predict the epidemiological trend of COVID-19 in Morocco and to assess the potential role of multiple preventive measures and strategies imposed by Moroccan authorities. The main features of the work include the well-posedness of the models and conditions under which the COVID-19 may become extinct or persist in the population. Parameter values have been estimated from real data and numerical simulations are presented for forecasting the COVID-19 spreading as well as verification of theoretical results.

Εξετάσθηκαν 930 παιδιά ηλικίας 37 μηνών από διάφορες περιοχές της Β. Ελλάδας και από όλα τα κοινωνικοοικονομικά στρώματα ώστε το δείγμα να είναι αντιπροσωπευτικό. Από την παρούσα εφαρμογή της δοκιμασίας της Griffiths στα παιδιά της χώρας μας διαπιστώθηκε ότι ο μέσος όρος των αναπτυξιακών δεικτών και των δύο κλιμάκων ήταν υψηλότερος σε σχέση με τους αντίστοιχους δείκτες του δείγματος της Griffiths. Αυτό σημαίνει ότι τα παιδιά αυτής της μελέτης εκτελούν νωρίτερα, σε μικρότερη δηλαδή χρονολογική ηλικία, τις περισσότερες δεξιότητες. Σύμφωνα με τα αποτελέσματα της μελέτης συμπεραίνεται ότι οι κινητικές κλίμακες της δοκιμασίας της Griffiths προσφέρουν τη δυνατότητα αντικειμενικής αξιολόγησης της κατάστασης του ρυθμού της κινητικής ανάπτυξης και της αποκάλυψης κάποιας λανθάνουσας παρέκκλισης από το φυσιολογικό.

description: The present study aimed at the standarisation of the motor subscales(locomotor and fine motor) of the Griffiths test noII on preschool aged children. 930 children were assessed, aged from 36 to 72 months, selected from various areas of Northern Greece and from all socioeconomic section of society, so that the sample was representative. Through the present application of the Griffiths test to the children in our country, we were able to realise that the average development quotients and the two subscales were higher compared to the relevant quotients of the Griffiths test. This means that the children of the present srudy execute earlier, that is, out younger age, most of the items included in the two motor subscales of the test. According to the results of the study, we can conclude that the motor subscales of the Griffiths test offer the possibility for an objective evaluation of the motor condition, the rate of motor development and the timely detection of a domant deviation. Finally, the higher developmental quotients of the children in this study fortify the need for the standarization of a test before it is applied to the population of a country

description: Research into the oxygen pressure leaching of zinc sulphide concentrates has identified that oxygen absorption is a rate-controlling process. In this study, the transfer of oxygen from air to aqueous sodium sulphite solutions by gas pumping impellers was studied as a simulation of the gas-liquid mass transfer step. A 200 litre right-cylindrical lucite mixing vessel with near-hemispherical bottom was employed. With this tank design, interference with impeller discharge is minimized and the environment approaches the ideal case of an impeller in the ocean. Four radially mounted baffles could be inserted to induce flow conditions characteristic of industrial mixing vessels. The effects of baffles and impeller type, diameter, immersion depth, and tip speed were evaluated in terms of the oxygen transfer rate, power consumption, and power efficiency of oxygen transfer. It was demonstrated that in the absence of baffling a critical tip speed exists, above which the impeller begins to pump gas at a rate proportional to the impeller tip speed. This critical tip speed is linked directly to the depth of immersion of the impeller on the basis of a theoretical energy balance at the impeller tip. The fit of experimental data to the theoretical was explained in terms of the geometry of the impeller and the shape of the gas vortex it produces. When baffling is introduced, the results obey the critical tip speed relation less accurately, as baffle-impeller interactions significantly alter the flow patterns and change the gas pumping mechanism to bubble capture from surface eddies. In the unbaffled vessel, axial flow impellers pump oxygen at lower rates and energy efficiencies than radial disc impellers, unless placed at shallow immersion. Gas pumping by dual impellers offers no advantage over a single radial disc impeller operating at the lower immersion depth. At a given impeller speed, oxygen transfer is increased by the addition of baffles, but power consumption increases at a faster rate so that the energy efficiency is lower than without baffles. However, it was possible with impellers of smaller diameter at a shallow immersion depth to sustain a vortex in the baffled vessel, which gave the largest rates and efficiencies of oxygen transfer. This suggests it is possible to reduce the degree of baffling, and that the rate and efficiency of oxygen transfer can be optimized through judicious selection of impeller diameter and baffle size.

description: In this paper, we analyze the scaling properties of a model that has as limiting cases the diffusion-limited aggregation (DLA) and the ballistic aggregation (BA) models. This model allows us to control the radial and angular scaling of the patterns, as well as, their gap distributions. The particles added to the cluster can follow either ballistic trajectories, with probability $P_{ba}$, or random ones, with probability $P_{rw}=1-P_{ba}$. The patterns were characterized through several quantities, including those related to the radial and angular scaling. The fractal dimension as a function of $P_{ba}$ continuously increases from $d_f\approx 1.72$ (DLA dimensionality) for $P_{ba}=0$ to $d_f\approx 2$ (BA dimensionality) for $P_{ba}=1$. However, the lacunarity and the active zone width exhibt a distinct behavior: they are convex functions of $P_{ba}$ with a maximum at $P_{ba}\approx1/2$. Through the analysis of the angular correlation function, we found that the difference between the radial and angular exponents decreases continuously with increasing $P_{ba}$ and rapidly vanishes for $P_{ba}>1/2$, in agreement with recent results concerning the asymptotic scaling of DLA clusters.

description: We report high-resolution optical absorption spectra for NdFe3(BO3)4 trigonal single crystal which is known to exhibit a giant magnetoelectric effect below the temperature of magnetic ordering TN = 33 K. The analysis of the temperature-dependent polarized spectra reveals the energies and, in some cases, symmetries and exchange splittings of Nd3+ 84 Kramers doublets. We perform crystal-field calculations starting from the exchange-charge model, obtain a set of six real crystal-field parameters, and calculate wave functions and magnetic g-factors. In particular, the values g(perpendicular) = 2.385, g(parallel) = 1.376 were found for the Nd3+ ground-state doublet. We obtain Bloc=7.88 T and |JFN|= 0.48 K for the values of the local effective magnetic field at liquid helium temperatures at the Nd3+ site and the Nd - Fe exchange integral, respectively, using the experimentally measured Nd3+ ground-state splitting of 8.8 cm-1. To check reliability of our set of crystal field parameters we model the magnetic susceptibility data from literature. A dimer containing two nearest-neighbor iron ions in the spiral chain is considered to partly account for quasi-one-dimensional properties of iron borates, and then the mean-field approximation is used. The results of calculations with the exchange parameters for Fe3+ ions Jnn = -6.25 K (intra-chain interactions) and Jnnn = -1.92 K (inter-chain interactions) obtained from fitting agree well with the experimental data.

Determination of the dynamic strength of iron at low temperature

description: Measurements of the stress sensitivity of the strain rate and of the strain vs stress in a titanium-doped, "interstitial free" (IF) iron were done at three temperatures, -20, -50 and -75° C. By application of a deformation model, based on a new theory of mobile dislocation density, these measurements permit the determination of (1) the constants of the power law describing the dislocation velocity as a function of the effective stress, and (2) the mean free dislocation path, which is descriptive of parabolic strain hardening. The theory is then used to calculate the microstructural parameters which determine the inelastic strain rate and the deformation resistance as they evolve, over time, with stress, stress rate and temperature. These parameters include the mobile and network dislocation densities, dislocation velocity, and effective stress. Theoretical predictions of the dynamic properties show excellent agreement with experiment. These properties include: (1) the stress sensitivity of the strain rate, as influenced by stress, stress rate and the magnitude of the stress decrease; (2) the nature and recovery time of the strain rate following a stress decrease; (3) the relative level of hard machine stress vs strain curves as a function of crosshead speed; and (4) the temperature dependence of both the microyield and macroyield stresses.

description: In this article, we study the stability of the space of asymptotic fermion states in (2+1)D, when long range interparticle interactions are present. This is done in the framework of bosonization, where the fermion propagator can be represented in terms of a vortex correlator. In particular, we discuss possible instabilities in the large distance behavior of the induced action for the vortex worldline.

description: Scanning tunneling microscopy and spectroscopy have been performed on superconducting La$_{2-x}$Sr$_{x}$CuO$_{4}$ ($x=0.06, 0.12, 0.16$, and 0.21) at 4.2 K. Atomically resolved surface topography has been observed on the $ab$ surface, which exhibits a one-dimensional structure corresponding to the buckling pattern of the orthorhombic phase. The tunneling spectra of all samples exhibit kinks at about $\pm 5$ meV in addition to the energy gap, indicating the existence of two energy scales. While the gap magnitude varies on the length scale of a few nm and steadily increases upon underdoping, the kink energy is spatially uniform on the surface and almost independent of the doping level.

description: We consider the reduced dynamics of a molecular chain weakly coupled to a phonon bath. With a small and constant inhomogeneity in the coupling, the excitation relaxation rates are obtained in closed form. They are dominated by transitions between exciton modes lying next to each other in the energy spectrum. The rates are quadratic in the number of sites in a long chain. Consequently, the evolution of site occupation numbers exhibits longer coherence lifetime for short chains only. When external source and sink are added, the rate equations of exciton occupation numbers are similar to those obtained earlier by Fröhlich to explain energy storage and energy transfer in biological systems. There is a clear separation of time scale into a faster one pertaining to internal influence of the chain and phonon bath, and a slower one determined by external influence, such as the pumping rate of the source, the absorption rate of the sink and the rate of radiation loss. The energy transfer efficiency at steady state depends strongly on these external parameters, and is robust against a change in the internal parameters, such as temperature and inhomogeneity. Excitations are predicted to concentrate to the lowest energy mode when the source power is sufficiently high. In the site basis, this implies that when sustained by a high power source, a sink positioned at the center of the chain is more efficient in trapping energy than a sink placed at its end. Analytic expressions of energy transfer efficiency are obtained in the high power and low power source limit. Parameters of a photosynthetic system are used as examples to illustrate the results.

description: Wie sollte man das Spanisch bezeichnen, das die in den USA lebenden Hispanoamerikaner sprechen – als „US-Spanisch“ oder als „Spanglish“? Diese Frage geht über ein reines Bezeichnungsproblem hinaus, spiegelt doch die Antwort darauf die Anerkennung und Würdigung einer ganzen Bevölkerungsgruppe, die sich häufig an den gesellschaftlichen Rand gedrängt oder gering geschätzt sieht. Sprachen sind eng verbunden mit ethnischen und sozialen Identitäten – Dialekte und Sprachen von Minderheiten werden vielfach als „Sprache der anderen“ oder gar als „Feindessprachen“ wahrgenommen. Derartige Beziehungen zwischen Sprache und Gesellschaft sind ein zentrales Forschungsgebiet des neuen Heidelberg Center for Ibero-American Studies (HCIAS): Innerhalb des Rahmenthemas „Räume und Dynamiken“ nähern sich die Wissenschaftlerinnen und Wissenschaftler den sozialen, kulturellen und umweltbedingten Realitäten der Makroregion Ibero-Amerika und ihren inneren und äußeren Entwicklungen, Transformationen und Verflechtungen.

description: Το μάθημα της ιστορίας ενώ διαμορφώνει κατευθύνσεις ανάπτυξης της ιστορικής συνείδησης στα μέλη μιας κοινωνίας από την άλλη όμως συνιστά μια προβληματική περιοχή όπου υπεισέρχονται γενικότερα εθνικά θέματα, κοινωνικές κατευθύνσεις αλλά και προβληματισμοί λόγω του ότι σε κάθε χώρα και σε κάθε περίοδο διαμορφώνονται διαφορετικές προοπτικές, διαφορετικοί σκοποί κτλ. Η εργασία μας εστιάστηκε στη μελέτη του μαθήματος της ιστορίας στο δημοτικό σχολείο ως προς τα ιστορικά γεγονότα και τα αντίστοιχα ιδεολογήματα κατά την περίοδο 1950-1960. Θα μπορούσαμε να πούμε ότι στην περίοδο αυτή η μεταλλακτική δύναμη του μαθήματος της ιστορίας διαμορφώνει πολλές φορές μια τυπολατρική μορφή σύλληψης της παιδείας για τα μεταγενέστερα χρόνια
description: In this dissertation, our concern is about the historical facts and ideological use of history in the elementary school during the period 1950-1960. We could say that the period 1950-1960 forms a kind of matrix-a distortional one many times, in order to create and develop ideological and educational directions. Also, the alternative force of history course forms many times a standardization of education for the coming years

description: The [C II] 158 micron line is an important emission line diagnostic in Photodissociation Regions (PDRs), but this emission line can also emerge from ionized gas. This work calculates the contribution of [C II] emission from ionized gas over a wide range of parameter space by considering the simplified case of an H+ region and PDR in pressure equilibrium. Additionally, these calculations also predict the strong correlation observed between [N II] 205 micron emission and [C II] discussed by previous authors. Overall, the results of these calculations have wide-ranging applications to the interpretation of [C II] emission in astrophysical environments.
