description: Il burnout è un fenomeno notoriamente molto diffuso tra i docenti di ogni grado di insegnamento. Questa tesi vuole indagare quali sono i principali fattori di stress nei docenti di scuola elementare del Canton Ticino e quali sono le caratteristiche personali che possono fungere da risorsa in situazioni difficili, quest’ultime causa di tensioni e nervosismo. Gli strumenti d’indagine sono delle interviste e la compilazione di questionari. Il campione oggetto di studio comprende docenti titolari di scuola elementare che esercitano, o hanno esercitato, la professione sul territorio del Canton Ticino e che hanno vissuto una situazione di forte stress, o burnout, durante la loro carriera. Gli intervistati appartengono a differenti fasce d’età che spaziano tra i 20 e i 65 anni. Per ognuna di queste, sono stati presi in analisi sia uomini che donne. I risultati dimostrano, confermando parzialmente le ipotesi formulate, che i principali fattori di stress riguardano generalmente le seguenti sei macrocategorie: la classe; le famiglie; le dinamiche socio-relazionali; la burocrazia; la formazione; il cambiamento. Mostrano inoltre che le caratteristiche fondamentali da possedere e da sviluppare per operare in serenità sono: pazienza, creatività, voglia di crescere professionalmente; autostima; oggettività; buona preparazione alle varie casistiche che potrebbero presentarsi in classe.

Publisher: name: arXiv
Year: 2011
Subjects: subject: Quantum Physics (quant-ph)

description: The approximate analytical bound state solution of the Schrödinger equation for the Manning-Rosen potential is carried out by taking a new approximation scheme to the orbital centrifugal term. The Nikiforov-Uvarov method is used in the calculations. We obtain analytic forms for the energy eigenvalues and the corresponding normalized wave functions in terms of the Jacobi polynomials or hypergeometric functions for different screening parameters 1/b. The rotational-vibrational energy states for a few diatomic molecules are calculated for arbitrary quantum numbers n and l with different values of the potential parameter α. The present numerical results agree within five decimal digits with the previously reported results for different 1/b values. A few special cases of the s-wave (l=0) Manning-Rosen potential and the Hulthén potential are also studied.

description: We study an optomechanical system in which the collective density excitations (Bogoliubov modes) of a Bose Einstein condensate (BEC) is coupled to a cavity field. We show that the optical force changes the frequency and the damping constant of the collective density excitations of the BEC. We further analyze the occurrence of normal mode splitting (NMS) due to mixing of the fluctuations of the cavity field and the fluctuations of the condensate with finite atomic two-body interaction. The NMS is found to vanish for small values of the two-body interaction. We further show that the density excitations of the condensate can be used to squeeze the output quantum fluctuations of the light beam. This system may serve as an optomechanical control of quantum fluctuations using a Bose Einstein condensate.

description: Background As part of the European Research Area vision, the European Commission is aiming to see the necessary transformations in R&I that will include the promotion of citizen science and societal engagement, the mainstreaming of Open Science practices, the fostering of brain and knowledge circulation, strengthening of academia-business collaboration and embodiment in a global Research and Innovation (R&I) ecosystem. The YUFE (Young Universities for the Future of Europe) alliance embraces this challenge in the YUFERING project by effectively contributing to pilot these needed transformations to improve and harmonise the conditions for R&I in Europe. Focusing on key elements of the ERA and in full alignment with the relevant SwafS call for proposals, YUFERING proposes ground-breaking transformation actions that will bring the partners one step closer to creating and realising a shared robust R&I vision, really committed with Open Science. More specifically, WP5 (led by Carlos III University of Madrid) aims to create a YUFE Open Science Strategy and look for a post-COVID-19 approach that states Open Science as ‘the new normal’ in YUFE Universities. In this regard, one of the main objectives of this project is the co-creation of a YUFE Open Education Training Suite on Open Science. Under the umbrella of Task 5.4., an informative/formative Open Science Calendar that aims to increase awareness on the Open Science pillars and practices among researchers, has been elaborated. Here we offer a customisable version of the calendar to be used by any institution in the world interested and committed to Open Science. Add your logos, your messages, your services for Open Science and enjoy!!! Please share alike in Twitter your version with the hashtag #YUFEOSCalendar. Resources to customise your Calendar The materials shared will provide you with everything you need to set up your own calendar. All material is created by the Uc3m YUFERING team and the illustrations used and licenses are properly indicated. It includes a PowerPoint file and also a guideline that can help you in the process.

Geometry of obstacle marks at instream boulders—integration of laboratory investigations and field observations
Creators: name: Schlömer, Oliver

Publisher: name: FID GEO

description: Obstacle marks are instream bedforms, typically composed of an upstream frontal scour hole and a downstream sediment accumulation in the vicinity of an obstacle. Local scouring at infrastructure (e.g. bridge piers) is a well‐studied phenomenon in hydraulic engineering, while less attention is given to the time‐dependent evolution of frontal scour holes at instream boulders and their geometric relations (depth to width, and length ratio). Furthermore, a comparison between laboratory studies and field observations is rare. Therefore, the morphodynamic importance of such scour features to fluvial sediment transport and morphological change is largely unknown. In this study, obstacle marks at boulder‐like obstructions were physically modelled in 30 unscaled process‐focused flume experiments (runtime per experiment ≥ 5760 min) at a range of flows (subcritical, clear‐water conditions, emergent and submerged water levels) and boundary conditions designed to represent the field setting (i.e. obstacle tilting, and limited thickness of the alluvial layer). Additionally, geometries of scour holes at 90 in‐situ boulders (diameter ≥ 1 m) located in a 50‐km segment of the Colorado River in Marble Canyon (AZ) were measured from a 1 m‐resolution digital elevation model. Flume experiments reveal similar evolution of local scouring, irrespective of hydraulic conditions, controlled by the scour incision, whereas the thickness of the alluvial layer and obstacle tilting into the evolving frontal scour hole limit incision. Three temporal evolution phases—(1) rapid incision, (2) decreasing incision, and (3) scour widening—are identified based on statistical analysis of spatiotemporal bed elevation time series. A quantitative model is presented that mechanistically predicts enlargement in local scour length and width based on (1) scour depth, (2) the inclination of scour slopes, and (3) the planform area of the frontal scour hole bottom. The comparison of field observations and laboratory results demonstrates scale invariance of geometry, which implies similitude of processes and form rather than equifinality.
description: We compared the size of local scour holes at boulders in the Colorado River to the dimensions of obstacle marks at boulder‐like obstructions generated in a laboratory flume at various hydraulic conditions. Based on the laboratory results, different temporal evolution phases of local scouring could be determined, while geometric properties of the local scour hole showed similitude, irrespective of spatial scale. A mechanistic model is formulated to assess the enlargement of local scour length and width based on scour depth.

description: Nell’ultimo secolo, la produzione globale sta causando cambiamenti climatici con ripercussioni sull’uomo e sull’ambiente che lo circonda. Il commercio e il consumo così frenetici, la maggiore accessibilità del mercato della moda e i bisogni personali di rinnovarsi, esprimersi e sentirsi coinvolti all’interno della società spingono i consumatori ad acquistare maggiormente e rendono la vita dei capi troppo breve rispetto alle loro funzione e qualità. Ciò ne consegue un enorme spreco, causando impatti ambientali evidenti. Le tecnologie stanno cambiando le nostre abitudini e la nostra società, e anche per la moda è necessario adattarsi a questa trasformazione. Gli strumenti digitali possono contribuire alla sostenibilità nelle fasi di progettazione e comunicazione riducendo tempistiche e sprechi.

description: We have obtained broad-band near-infrared photometry for seven Galactic star clusters (M92, M15, M13, M5, NGC1851, M71 and NGC6791) using the WIRCam wide-field imager on the Canada-France-Hawaii Telescope, supplemented by images of NGC1851 taken with HAWK-I on the VLT. In addition, 2MASS observations of the [Fe/H] ~ 0.0 open cluster M67 were added to the cluster database. From the resultant (V-J)-V and (V-Ks)-V colour-magnitude diagrams (CMDs), fiducial sequences spanning the range in metallicity, -2.4 < [Fe/H] < +0.3, have been defined which extend (for most clusters) from the tip of the red-giant branch (RGB) to ~ 2.5 magnitudes below the main-sequence turnoff. These fiducials provide a valuable set of empirical isochrones for the interpretation of stellar population data in the 2MASS system. We also compare our newly derived CMDs to Victoria isochrones that have been transformed to the observed plane using recent empirical and theoretical colour-Teff relations. The models are able to reproduce the entire CMDs of clusters more metal rich than [Fe/H] ~ -1.4 quite well, on the assumption of the same reddenings and distance moduli that yield good fits of the same isochrones to Johnson-Cousins BV(RI)C photometry. However, the predicted giant branches become systematically redder than the observed RGBs as the cluster metallicity decreases. Possible explanations for these discrepancies are discussed.

The promise of returning home after mild traumatic brain injury
Creators: name: Nish, Bonnie
Publisher: name: University of British Columbia
Year: 2020

description: Trauma is anything that happens to us, physically or psychically, that is beyond our capacity to cope given our personal circumstances and development. Trauma devastates individuals and those who support them. Brain injuries, whether considered mild, moderate, or severe, are a common source of trauma. Mild Traumatic Brain Injuries (MTBI) are underreported injuries and can have long-lasting, life-altering effects, and even result in death. Experts have speculated that by 2020, MTBI would be one of the major causes of death around the world (Gururajc et al., 2007). The significance of this dissertation is to personalize the experience of MTBI so that others can recognize themselves in this work. This dissertation’s contribution is to open the MTBI field to personal stories in the first-person narrative through poetic works and life writing in order to expand the understanding of MTBI and its profound effects on an individual and those in relationship to them. I first examine my own history of becoming a writer and where I fit into the fields of poetic inquiry and life writing. Through this process, I examine the threads of trauma that have run throughout my life to find how they have affected my recovery from MTBI and what kinds of care I encountered throughout. My engagement with my life-writing and poetry are key to my healing.
Progressive Changes in Magma Transport at the Active Serreta Ridge, Azores

description: Volcanism in the Eastern Azores Plateau occurs at large central volcanoes and along subaerial and submarine fissure zones, resulting from a mantle melting anomaly combined with transtensional stresses. Volcanic structures are aligned WNW-ESE and NW-SE, reflecting two tectonic stress fields that control the direction of lateral melt transport. Terceira Island is influenced by both stress fields, dividing the island into an eastern and western part. Several submarine volcanic ridges with variable orientations are located west of Santa Bárbara, the youngest central volcano on Terceira. Major, trace element and Sr-Nd-Pb-Hf isotope compositions from submarine lavas and glasses, in part associated with the 1998–2001 Serreta Ridge eruption, vary between different lava suites, suggesting a formation from different mantle sources. Submarine lavas are more primitive than those from Santa Bárbara volcano, indicating that they are not laterally connected with the shallow magma reservoir located in 2- to 5-km depth beneath the central volcano. Mineral thermobarometric data suggest that the older Serreta magmas were laterally transported at depths >5 km from Santa Bárbara predominantly in WNW direction. We propose that lithospheric extension controls magma transport from the central volcano to Serreta Ridge. The youngest Serreta lavas differ from Santa Bárbara and other submarine ridges in having less radiogenic Pb and higher Hf isotope ratios representing a new magma pulse ascending from the mantle. We conclude that lateral magma transport and the morphology of volcanic ridges are controlled by tectonic stresses in the lithosphere, whereas vertical melt transport is initiated by processes in the mantle.

description: Data assimilation aims to blend incomplete and inaccurate data with physics-based dynamical models. In the Earth's radiation belts, it is used to reconstruct electron phase space density, and it has become an increasingly important tool in validating our current understanding of radiation belt dynamics, identifying new physical processes, and predicting the near-Earth hazardous radiation environment. In this study, we perform reanalysis of the sparse measurements from four spacecraft using the three-dimensional Versatile Electron Radiation Belt diffusion model and a split-operator Kalman filter over a 6-month period from 1 October 2012 to 1 April 2013. In comparison to previous works, our 3-D model accounts for more physical processes, namely, mixed pitch angle-energy diffusion, scattering by Electromagnetic Ion Cyclotron waves, and magnetopause shadowing. We describe how data assimilation, by means of the innovation vector, can be used to account for missing physics in the model. We use this method to identify the radial distances from the Earth and the geomagnetic conditions where our model is inconsistent with the measured phase space density for different values of the invariants μ and K. As a result, the Kalman filter adjusts the predictions in order to match the observations, and we interpret this as evidence of where and when additional source or loss processes are active. The current work demonstrates that 3-D data assimilation provides a comprehensive picture of the radiation belt electrons and is a crucial step toward performing reanalysis using measurements from ongoing and future missions.

description: The response of the upper atmosphere to equatorial Kelvin waves with a period of ∼3 days, also known as ultrafast Kelvin waves (UFKWs). The whole atmosphere model Ground-to-topside model of Atmosphere and Ionosphere for Aeronomy (GAIA) is used to simulate the UFKW events in the late summer of 2010 and 2011 as well as in the boreal winter of 2012/2013. When the lower layers of the model below 30-km altitude are constrained with meteorological data, GAIA is able to reproduce salient features of the UFKW in the mesosphere and lower thermosphere as observed by the Aura Microwave Limb Sounder. The model also reproduces ionospheric response, as validated through comparisons with total electron content data from the Gravity field and steady-state Ocean Circulation Explorer satellite as well as with earlier observations. Model results suggest that the UFKW produces eastward-propagating ∼3-day variations with zonal wavenumber 1 in the equatorial zonal electric field and F region plasma density. Model results also suggest that for a ground observer, identifying ionospheric signatures of the UFKW is a challenge because of ∼3-day variations due to other sources. This issue can be overcome by combining ground-based measurements from different longitudes. As a demonstration, we analyze ground-based magnetometer data from equatorial stations during the 2011 event. It is shown that wavelet spectra of the magnetic data at different longitudes are only in partial agreement, with or without a ∼3-day peak, but a spectrum analysis based on multipoint observations reveals the presence of the UFKW.

description: Abstract Inspired by the first rechargeable Mg battery about 20 years ago, based on a Chevrel phase cathode, a Mg foil anode, and a magnesium organo-aluminate electrolyte, research on rechargeable batteries using sulfur as the cathode together with Mg as the anode has gained substantial and increasing interest. In particular, the safety characteristics of magnesium–sulfur (Mg–S) batteries, the high abundance of both magnesium and sulfur, and the high theoretical volumetric energy density of magnesium render this system specifically interesting for mobile applications that require high volumetric energy densities, i.e., the automotive and aviation sector. While the development of Mg–S batteries is still at a nascent stage, some breakthroughs have already been accomplished. Consequently, it appears necessary to provide a comprehensive up-to-date review about the current achievements to facilitate further improvements in this field. In this review, the state of the art in Mg–S batteries is summarized, focusing on sulfur conversion cathodes, magnesium anode materials, currently employed electrolyte systems, as well as on current collectors and separator design. In addition, the challenges and some possible future work to realize a practically applicable and technically viable Mg–S battery are highlighted.

description: The time-domain controlled source electromagnetic method is a geophysical prospecting tool applied to image the subsurface resistivity distribution on land and in the marine environment. In its most general set-up, a square-wave current is fed into a grounded horizontal electric dipole, and several electric and magnetic field receivers at defined offsets to the imposed current measure the electromagnetic response of the Earth. In the marine environment, the application often uses only inline electric field receivers that, for a 50% duty-cycle current waveform, include both step-on and step-off signals. Here, forward and inverse 1D modelling is used to demonstrate limited sensitivity towards shallow resistive layers in the step-off electric field when transmitter and receivers are surrounded by conductive seawater. This observation is explained by a masking effect of the direct current signal that flows through the seawater and primarily affects step-off data. During a step-off measurement, this direct current is orders of magnitude larger than the inductive response at early and intermediate times, limiting the step-off sensitivity towards shallow resistive layers in the seafloor. Step-on data measure the resistive layer at times preceding the arrival of the direct current signal leading to higher sensitivity compared to step-off data. Such dichotomous behaviour between step-on and step-off data is less obvious in onshore experiments due to the lack of a strong overlying conductive zone and corresponding masking effect from direct current flow. Supported by synthetic 1D inversion studies, we conclude that time-domain controlled source electromagnetic measurements on land should apply both step-on and step-off data in a combined inversion approach to maximize signal-to-noise ratios and utilize the sensitivity characteristics of each signal. In an isotropic marine environment, step-off electric fields have inferior sensitivity towards shallow resistive layers compared to step-on data, resulting in an increase of non-uniqueness when interpreting step-off data in a single or combined inversion.

description: We present the first low-temperature thermochronology data from northernmost Ellesmere Island (Canadian Arctic), along with palynological data from Paleogene sediments. Our study area is part of the >2,500-km-long Eurekan deformation belt that formed across the High Arctic during the Eocene. The aim of this study is to investigate the exhumation of the Eurekan belt and potential relationships with the opening of the North Atlantic, as well as with environmental changes of the Arctic. Our data show that the Canadian Arctic margin was characterized by stretching and basin formation during the Paleocene. Sediment deposition occurred in a coastal swamp environment under a warm and humid climate that lasted into the early Eocene. Exhumation of northern Ellesmere Island was episodic and was presumably controlled by strike-slip movements along the De Geer Fracture Zone between Svalbard and Greenland. Enhanced exhumation of northern Ellesmere Island occurred ~66–60 Ma, ~55–48 Ma, 44–38 Ma, and 34–26 Ma. These exhumation periods largely correlate with changes of spreading rates and movement directions of the Norwegian-Greenland Sea. Main topographic growth along the Eurekan belt was temporally coincident with deposition of ice-rafted debris off eastern Greenland. We suggest that Eurekan topography growth was an important trigger for glacier formation in Greenland. The cessation of rapid exhumation at ~26 Ma can be explained by continental separation between Greenland and Svalbard, which decoupled northern Ellesmere Island from strike-slip movements along the De Geer Fracture Zone, eventually leading to the opening of the Fram Strait.

description: Per far fronte all’aumento costante dei fallimenti è necessario un programma che avvicini i commercianti (specie quelli di micro, piccole e medie imprese) alle esigenze dei consumatori. Secondo le più attuali strategie di marketing è la figura del cliente a “dirigere” il mercato. Mai come oggi la varietà dell’offerta ha permesso al consumatore di assumere un ruolo centrale e determinante, la produzione è orientata verso un cliente specifico, personalizzata, plasmata e mirata a seconda delle sue esigenze. Sostenibilità, rispetto, trasparenza, flessibilità, ecc. sono valori fondamentali a cui l’acquirente presta sempre maggior attenzione. Non si tratta di cambiare servizi e prodotti ma d’incentivare un comportamento più etico per poi poterlo comunicare. Helvetia – Clienti e commercianti è un programma completo volto a salvaguardare le imprese locali e sensibilizzare i clienti riguardo a “buone pratiche di attività”. Un progetto che permette di comparare l’offerta territoriale secondo le più sofisticate strategie di mercato e che aiuta anche i più piccoli commercianti, fornendo loro gli strumenti necessari per rendere competitivo il proprio operato. Non solo una vetrina ma un vero e proprio punto di riferimento per “domanda e offerta”, un servizio che, per primo, s’incarica quale modello esemplare di attività, comunicando la Confederazione ed i suoi valori come se fosse una brand.

description: In the present work it is studied the fermionic van Hemmen model for the spin glass (SG) with a transverse magnetic field $Γ$. In this model, the spin operators are written as a bilinear combination of fermionic operators, which allows the analysis of the interplay between charge and spin fluctuations in the presence of a quantum spin flipping mechanism given by $Γ$. The problem is expressed in the fermionic path integral formalism. As results, magnetic phase diagrams of temperature versus the ferromagnetic interaction are obtained for several values of chemical potential $μ$ and $Γ$. The $Γ$ field suppresses the magnetic orders. The increase of $μ$ alters the average occupation per site that affects the magnetic phases. For instance, the SG and the mixed SG+ferromagnetic phases are also suppressed by $μ$. In addition, $μ$ can change the nature of the phase boundaries introducing a first order transition.

description: Con questo lavoro di ricerca ho voluto realizzare un progetto scientifico legato allo sviluppo sostenibile, che potesse coinvolgere gli allievi in un’esperienza al di fuori del contesto scolastico, valutando in itere le loro reazioni, considerando tre parametri fondamentali quali la motivazione, l’apprendimento e la visione sugli aspetti legati allo sviluppo sostenibile. Il progetto ha coinvolto gli allievi di prima media nello studio dell’utilizzo e dello sfruttamento dell’acqua potabile, investigando le tappe del suo percorso dalla sorgente all’imbottigliamento e oltre. Culmine del progetto è stata la visita ad una fabbrica di imbottigliamento della regione del Monte Tamaro, tappa che ha aperto il percorso didattico e ha permesso di affrontare diversi temi disciplinari (e non) sull’acqua, argomento previsto in prima media. I risultati, analizzati sulla base di dati raccolti lungo il percorso tramite un diario personale e dalle produzioni scritte degli allievi, hanno evidenziato quanto questo tipo di esperienza abbia mantenuto elevato il livello di motivazione negli allievi e abbia contribuito positivamente all’apprendimento e allo sviluppo di un tipo di pensiero più ampio e sistemico nei confronti dello sviluppo sostenibile.

description: Reliable and accurate weather forecasts, particularly those of rainfall and its extremes, have the potential to improve living conditions in densely populated southern West Africa (SWA). The limited availability of observations has long impeded a rigorous evaluation of current state-of-the-art forecast models. The field campaign of the Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa (DACCIWA) project in June–July 2016 has created an unprecedentedly dense set of measurements from surface stations and radiosondes. Here we present results from a comprehensive evaluation of both numerical model forecasts and satellite products using these data on a regional and local level. Results reveal a substantial observational uncertainty showing considerable underestimations in satellite estimates of rainfall and low-cloud cover with little correlation at the local scale. Models have a dry bias of 0.1–1.9 mm·day−1 in rainfall and too low column relative humidity. They tend to underestimate low clouds, leading to excess surface solar radiation of 43 W·m−2. Remarkably, most models show some skill in representing regional modulations of rainfall related to synoptic-scale disturbances, while local variations in rainfall and cloudiness are hardly captured. Slightly better results are found with respect to temperature and for the post-onset rather than for the pre-onset period. Delicate local features such as the Maritime Inflow phenomenon are also rather poorly represented, leading to too cool, dry and cloudy conditions at the coast. Differences between forecast days 1 and 2 are relatively small and hardly systematic, suggesting a relatively quick error saturation. Using explicit convection leads to more realistic spatial variability in rainfall, but otherwise no marked improvement. Future work should aim at improving the subtle balance between the diurnal cycles of low clouds, surface radiation, the boundary layer and convection. Further efforts are also needed to improve the observational system beyond field campaign periods.
Search for High Mass Resonances Decaying to Muon Pairs in $\sqrt{s}=1.96$ TeV $p\bar{p}$ Collisions

description: We present a search for a new narrow, spin-1, high mass resonance decaying to $μ^+μ^- + X $, using a matrix element based likelihood and a simultaneous measurement of the resonance mass and production rate. In data with 4.6 fb$^{-1}$ of integrated luminosity collected by the CDF detector in $p\bar{p}$ collisions at $\sqrt{s}=1960$ GeV, the most likely signal cross section is consistent with zero at 16\% confidence level. We therefore do not observe evidence for a high mass resonance, and place limits on models predicting spin-1 resonances, including $M > 1071$ GeV/$c^2$ at 95\% confidence level for a $Z'$ boson with the same couplings to fermions as the $Z$ boson.

description: Mafic lavas of Cenozoic age are widely distributed in northeast China and received much attention as an important part of the Circum-Pacific volcanic belt. The age constraints for the volcanic activity were determined mostly by K/Ar and 40Ar/39Ar methods. We present zircon (U–Th)/He ages obtained on the thermally overprinted sands directly underlying a basaltic lava. This thermochronometer is insensitive to weathering and not biased by excess argon, thus it can express accurately the age of thermal effect of the lava flow. As a regional cooling age reference, three granite samples were dated from basement units that have not been thermally influenced by the basalt eruptions. The reference granite samples revealed well-defined Cretaceous (U–Th)/He-ages, while 20 zircon crystals from the sand below the basalt lava revealed a prominent Miocene (U–Th)/He age component of 9.33 ± 0.24 Ma. Raman spectroscopy of these zircon crystals supports their thermally overprinted character. We infer that the sand sample has experienced significant thermal overprint by the overlying basalt lava leading to thermal reset of the majority of the detrital zircon crystals. The obtained age is thus interpreted as the eruption age of the basalt lava. The Huanan basalt flow thus belongs to volcanics of the Laoyeling episode in NE China.
DMFT vs Second Order Perturbation Theory for the Trapped 2D Hubbard-Antiferromagnet

description: In recent literature on trapped ultracold atomic gases, calculations for 2D-systems are often done within the Dynamical Mean Field Theory (DMFT) approximation. In this paper, we compare DMFT to a fully two-dimensional, self-consistent second order perturbation theory for weak interactions in a repulsive Fermi-Hubbard model. We investigate the role of quantum and of spatial fluctuations when the system is in the antiferromagnetic phase, and find that, while quantum fluctuations decrease the order parameter and critical temperatures drastically, spatial fluctuations only play a noticeable role when the system undergoes a phase transition, or at phase boundaries in the trap. We conclude from this that DMFT is a good approximation for the antiferromagnetic Fermi-Hubbard model for experimentally relevant system sizes.
