description: The monitoring of quiescent emission from neutron star transients with accretion outbursts long enough to significantly heat the neutron star crust has opened a new vista onto the physics of dense matter. In this paper we construct models of the thermal relaxation of the neutron star crust following the end of a protracted accretion outburst. We confirm the finding of Shternin et al., that the thermal conductivity of the neutron star crust is high, consistent with a low impurity parameter. We describe the basic physics that sets the broken power-law form of the cooling lightcurve. The initial power law decay gives a direct measure of the temperature profile, and hence the thermal flux during outburst, in the outer crust. The time of the break, at hundreds of days post-outburst, corresponds to the thermal time where the solid transitions from a classical to quantum crystal, close to neutron drip. We calculate in detail the constraints on the crust parameters of both KS 1731-260 and MXB 1659-29 from fitting their cooling lightcurves. Our fits to the lightcurves require that the neutrons do not contribute significantly to the heat capacity in the inner crust, and provide evidence in favor of the existence of a neutron superfluid throughout the inner crust. Our fits to both sources indicate an impurity parameter of order unity in the inner crust.

Methods of studying the effects of the surroundings on outdoor activities in urban public places

Publisher: name: University of British Columbia

description: This study was concerned with selecting methods drawn from ecology and ethology that could be applied to evaluating the behaviour of people in downtown public places. Time-sampling and behavioural mapping proved to be useful objective methods of observing and recording people's activities in four public places in Vancouver, British Columbia. Information on user activities was applied to evaluate the relationship between behaviour and the physical environment in a park, a square and two plazas. In each place there were examples of the impact of environmental factors such as sun direction, shadow patterns, wind tunnels, and edge conditions on the location and the intensity of user activities. Too often the design of urban spaces has not been sympathetic to the reactions of people to their surroundings. This inadequacy has brought about a lack of use of these spaces. Traditional techniques of behavioural research have not been able to improve this situation. The observational approach developed here is capable of providing objective information on the ways in which physical surroundings affect people's activities.

description: W 1972 roku w Stanach Zjednoczonych powołano do życia organizację, która w dziedzinie nauki, kształcenia i edukacji wykorzystuje techniki L. Rona Hubbarda (1911–1986), założyciela Kościoła Scjentologicznego – chyba jednego z najbardziej kontrowersyjnych nowych ruchów religijnych. Applied Scholastics (ApS) rozpoczęła działalność od szeregu projektów, których głównym, wciąż aktualnym, celem było promowanie i rozwijanie skutecznych programów edukacyjnych dla nauczycieli, trenerów biznesu, edukatorów, rodziców, dzieci i ludzi we wszystkich obszarach życia, potrzebujących „naprawy nawyków uczenia się tychże osób w celu zwiększenia osobistej aktywności, skutecznego uczenia się”. Podstawą metodologiczną działania ApS stała się tzw. Study Tech – technologia uczenia się, która pozwala „osiągnąć sukces w dowolnej dziedzinie wiedzy i zdobyć umiejętność wykorzystania z zastosowaniem tej wiedzy”. Ale czy tylko edukacyjne cele obiera owa odnoga Kościoła Hubbarda? Czy naprawdę edukatorzy ApS nie mają innych intencji i dążeń?
Experimentally Biased Molecular Dynamics Simulations Using Neutron Reflection Data

description: Structural modeling of proteins and characterization of their equilibrium properties is an essential part of understanding the complexities of organic matter. In addition, a wide array of biological functions occur at or are regulated by a lipid membrane. For this reason, characterization of proteins atbilayer interfaces is a crucial research pursuit. Neutron reflectometry (NR) is a powerful experimental technique for characterizing some of the interaction of proteins with lipid bilayers. Molecular dynamics (MD) simulations providea computational framework to model details beyond what is accessible in experiment. Traditionally, these two methods are performed independently and their results are used in complement to one another. In this work, a new method is developed and explored in order to integrate NR data into MD simulations. The algorithm takes the real{spacemodel of the protein derived from NR scattering data and compares it to the corresponding data calculated from simulation, updating this information as the simulation progresses. This comparison is used to construct a potentialthat biases the protein's dynamics in order to garner better agreement between the MD and NR data. First, a review is conducted of MD simulations, NR scattering, and thespecific experimental systems under investigation. This review gives a general sense of how other experimental techniques and MD simulations are integrated and how NR data may be used in simulation. Next, an analysisof the effect biasing has on the dynamics of a system is explored. This motivates the use of a linear bias potential.After supplying motivation for the method, details of the implementation are presented. The linear difference of the NR and MD data is used in the potential, and the MD data is calculated using two methods. In one method, the data is calculated only taking into account the protein conformationlocally in time (memoryless bias). In the other, the running average of the data is tracked and used in the comparison to NR (histories bias). The effectiveness of these two methods is explored on two model systems. The first system is a small helical peptide that has degrees of freedomequivalent to a rigid rod, under the energy scales explored. This system is not studied using neutron data, but rather a highly artificial potential is generated to represent only a confined subset of available conformations. Since the data is a reduction of the structure from three dimensions to one, the effects of the bias are not known before the simulations are performed.

description: Riassunto ­– Oggi la scuola è diventata un luogo che non riesce più a realizzare pratiche educative incisive nella vita dei giovani, poiché si pone come un’istituzione formativa che non può fronteggiare le sfide lanciate da una società sempre più complessa. Emerge, pertanto, la necessità educativa di realizzare progetti di vita non soltanto didattici e istruttivi, ma attraversati anche e soprattutto da dinamiche esistenziali. Queste riflessioni portano al centro del dibattito pedagogico il ruolo fondamentale che le competenze empatiche potrebbero svolgere a livello educativo. Si pone, così, l’urgenza di portare avanti azioni educative relative alla Didattica delle emozioni, ovvero quel programma di intervento utilizzato nelle scuole, che consiste nel rendere consapevoli bambini, adolescenti e preadolescenti in età scolare, dell’esistenza di un bagaglio emotivo interno da salvaguardare, da attraversare e da nominare.

description: Riassunto – L’articolo esplora il legame tra la scuola, la socializzazione dei ruoli di genere e la povertà educativa. Partendo da una panoramica sul fenomeno della povertà educativa, l’articolo si concentra sulla sua comprensione attraverso la lente del genere, sottolineando come le aspettative e gli stereotipi di genere influenzino l’accesso ad una educazione di qualità. Successivamente, vengono presentati dati comparativi riguardanti le scelte di genere nel contesto scolastico, evidenziando disparità e squilibri. Infine, l’articolo propone strategie per decostruire gli stereotipi di genere, offrendo elementi critici utili per la formazione dei docenti e per una più equa educazione di genere. Questa analisi mira a fornire strumenti teorici e pratici per affrontare la povertà educativa in una prospettiva di genere, contribuendo al dibattito su come rendere le pratiche scolastiche declinate all’educazione ai generi.

description: Riassunto – L’adozione è una realtà complessa, dalle molteplici sfaccettature, criticità, risorse. Tra le altre peculiarità, i minori che sono stati adottati possono avere le proprie origini in diverse zone dell’Italia ma anche in numerosi paesi del mondo, nell’adozione internazionale ma anche in quella nazionale che riguarda bambine/i di origine straniera in stato di abbandono sul suolo italiano. Spesso questi/e bambini/e portano in sé tratti somatici e colori della pelle differenti da quelli ancora prevalenti nel contesto italiano e hanno storie complesse (tanto più è elevata l’età all’adozione), caratterizzate da ripetute fratture, perdite, lutti, discontinuità, peculiarità che i contesti scolastici devono tenere in considerazione e accogliere. Possibilmente in prospettiva educativa interculturale. La presenza a scuola di bambini/e adottati/e, di origine straniera e non, è una realtà che esiste da decenni, tuttavia è relativamente recente il consolidarsi dell’impegno degli esperti riguardo alla necessità di creare strumenti e protocolli specifici per un’accoglienza preparata, sensibile e competente. Le Linee guida per favorire il diritto allo studio delle alunne e degli alunni che sono stati adottati, del 2014 e del 2023, nascono con l’obiettivo di fornire conoscenze e linee di indirizzo teorico-metodologico che aiutino la scuola a garantire ai bambini e ai ragazzi e alle loro famiglie, strumenti che favoriscano il loro percorso di crescita. Nell’analizzare alcuni dei principali aspetti del documento, in particolare del 2023, anche con il presente contributo, ci si pone l’obbiettivo di diffonderne la conoscenza.

description: We report a molecular dynamics study of ab initio quality of the ferroelectric phase transition in crystalline PbTiO3. We model anharmonicity accurately in terms of potential energy and polarization surfaces trained on density functional theory data with modern machine learning techniques. Our simulations demonstrate that the transition has a strong order-disorder character, in agreement with diffraction experiments, and provide fresh insight into the approach to equilibrium across the phase transition. We find that the emergence and disappearance of the macroscopic polarization is driven by dipolar switching at the nanometer scale. We also computed the infrared optical absorption spectra in both the ferroelectric and the paraelectric phases, finding good agreement with the experimental Raman frequencies. Often, the almost ideal displacive character of the soft mode detected by Raman scattering in the paraelectric phase has been contrasted with the order-disorder character of the transition suggested by diffraction experiments. We settle this issue by showing that the soft mode coexists with a strong Debye relaxation associated with thermal disordering of the dipoles. The Debye relaxation feature is centered at zero frequency and appears near the transition temperature in both the ferroelectric and the paraelectric phases.

description: From the beginning of the century there has been an awakening and dawning consciousness of the psychology of childhood and adolescence. My efforts in the foregoing paper are confined chiefly to parent child relationships to point out what I believe to be near ideal situations as possible. Individual freedom of the child is the goal set as the desired end in rearing a child. By correlating the work of some very prominent child psychologists and adding a few original thoughts, I hope to give what I believe to be highlights and rearing children intelligently in the average home with the average parent and the average child.

description: A dynamic model of human respiratory mechanics is developed to aid in the design and development of pressure-compensated oxygen masks worn by combat aircrew. Breathing models of varying complexity are formulated using the bond graph method to convey key elements of the system. A simple respiratory mask model containing inhalation and exhalation check valves is combined with the respiratory mechanics model. The system state equations are derived for each of the models presented and constitutive relations are described. Numerical solution of the system state equations is shown to capture dissipative and energy storage effects in respiratory tract and compliant elements of the system. The inclusion of air flow inertance in the model is shown to simplify the state equations by eliminating a non-linear algebraic loop. Respiratory mask performance metrics are presented and results from several case studies with variations in the lung characteristics and breathing scenarios are presented to demonstrate the effectiveness of the model in predicting key physiological measures, reported in the form of flow-volume loops, work of breathing, and mask cavity pressures.
Nonsequential Double Ionization with Polarization-gated Pulses

description: We investigate laser-induced nonsequential double ionization by a polarization-gated laser pulse, constructed employing two counter-rotating circularly polarized few cycle pulses with a time delay $T_{d}$. We address the problem within a classical framework, and mimic the behavior of the quantum-mechanical electronic wave packet by means of an ensemble of classical electron trajectories. These trajectories are initially weighted with the quasi-static tunneling rate, and with suitably chosen distributions for the momentum components parallel and perpendicular to the laser-field polarization, in the temporal region for which it is nearly linearly polarized. We show that, if the time delay $T_{d}$ is of the order of the pulse length, the electron-momentum distributions, as functions of the parallel momentum components, are highly asymmetric and dependent on the carrier-envelope (CE) phase. As this delay is decreased, this asymmetry gradually vanishes. We explain this behavior in terms of the available phase space, the quasi-static tunneling rate and the recollision rate for the first electron, for different sets of trajectories. Our results show that polarization-gating technique may provide an efficient way to study the NSDI dynamics in the single-cycle limit, without employing few-cycle pulses.

description: We report subarcsecond images of the high-mass star forming region Onsala 1 (ON 1) made with the Submillimeter Array (SMA) at 0.85 mm and the Very Large Array at 1.3 cm and 3.6 cm. ON~1 is one of the smallest ultracompact HII regions in the Galaxy and exhibits various star formation signposts. With our VLA and SMA observations, two new cm-wave sources and five sub-mm dust sources, respectively, within a field of ~3" (corresponding to a linear scale of 0.05 pc) are identified, indicating the multiplicity at the center of the ON 1 region. The dust and gas masses of these sub-mm sources are in the range of 0.8 to 6.4 M_sun. Among the five sub-mm dust sources, SMA2, with a dust and gas mass of 2.6 M_sun, demonstrates several star formation signatures, and hence likely represents an intermediate-mass (or even high-mass) star forming core. Due to the low star formation efficiency of ~10%, we suggest that star formation in the ON 1 region will continue. For example, SMA4 and SMA5 are not associated with any star formation signatures and likely mark star formation cores at very early evolutionary stages.

Il tema della “cura” verrà affrontato con un approccio pedagogico nell’ambito educativo, in particolare quello scolastico e della formazione. Pertanto si farà riferimento non tanto all’accezione sanitaria e medica del termine, quanto piuttosto a quella che viene definita “cura autentica”, la quale prevede l’esercizio di una relazione in cui chi educa è capace di intravedere la “possibilità di essere” in “ruoli futuribili” nelle persone in situazione di svantaggio – nello specifico con disabilità o detenute. Considerando la cura come un concetto polisemico approfondiremo la necessità di riferirsi a testimonianze di esperienze di cura dando voce agli stessi soggetti “curati”.

MATERIAL
2 ♂ (detailed information in Table S1; https://doi.org/ 10.5061/dryad.b8gtht7mh).
DIAGNOSIS
This species is best separated by examination of genitalia. In male genitalia, the slender valva with the short, fingershaped basal process and the two patches of 4-5 cornuti on the vesica unambiguously separates this species from its congeners. In female genitalia, the pouch-like projection is devoid of sclerotization, and the corpus bursae bears a longitudinal signum.
DISTRIBUTION
INDONESIA: Java, Sumatra; PHILIPPINES: Mindoro, Panay; VIETNAM. Collected at altitudes between 150 and 400 m on the Philippines.
REMARKS
This is the first record of this species from the Philippines.

description: We investigate the spin dynamics of high-mobility two-dimensional electrons in GaAs/AlGaAs quantum wells grown along the $[001]$ and $[110]$ directions by time-resolved Faraday rotation at low temperatures. In measurements on the $(001)$-grown structures without external magnetic fields, we observe coherent oscillations of the electron spin polarization about the effective spin-orbit field. In non-quantizing magnetic fields applied normal to the sample plane, the cyclotron motion of the electrons rotates the effective spin-orbit field. This rotation leads to fast oscillations in the spin polarization about a non-zero value and a strong increase in the spin dephasing time in our experiments. These two effects are absent in the $(110)$-grown structure due to the different symmetry of its effective spin-orbit field. The measurements are in excellent agreement with our theoretical model.

description: The Geisinger Rural Aging Study (GRAS) was initiated between 1994-99 as a longitudinal study of health outcomes in relation to nutritional status among 21,645 individuals ≥65-years of age. At the time of initiation, the participants were recruited from within the Geisinger Health System service area located in about 25 counties of north central and eastern Pennsylvania. Active participant data collection is complete but passive data collected through the Electronic Health Record continues for those surviving. Prior patient reported data were collected at baseline and at a rescreening visit occurring 3-4 years after baseline, using questionnaires that encompass multiple domains of nutrition risk. Our investigations have found high prevalence of poor-quality diets, obesity, and ill health. Low diet quality as revealed by the Diet Quality Screening Questionnaire (DQSQ) is associated with outcomes measured within our electronic medical record (low body mass index, increased co-morbidity, and increased mortality risk). The GRAS dataset currently spans more than two decades including patient reported data, clinical data captured within an electronic medical record, and includes novel sub-cohorts such as the oldest old (≥85 years) and centenarians (≥100 years).

La Commissione europea ha individuato l’Educazione Digitale, di cui l’IL è parte, come uno dei fattori chiave per realizzare entro il 2025 una comune European Education Area; tuttavia, le competenze digitali e di IL sono declinate in modo eterogeneo in Europa. La seconda parte dell’articolo restituisce due azioni del progetto: una mappatura di tali declinazioni nei rispettivi quadri nazionali e locali, realizzata con i docenti, e un questionario sull’IL a cui hanno risposto 1.955 studenti europei. Infine, il MOOC realizzato dal progetto, ora accessibile a tutti in italiano e inglese, è presentato come risposta per promuovere l’Information Literacy come capacità di leggere in modo critico i processi di trasformazione in atto dell’attuale ecosistema informativo.

A typical system has many levels of protection ranging from physical to data-oriented to access and authorization control. In this project, we plan to incorporate computer vision techniques to carry out the authentication and authorization techniques. For the authentication we plan to use facial recognition, and once the user is verified, he is provided access to his account. At all points of user interaction with the App the user face will be monitored to make sure that user is still around. The session details and the user face will be monitored constantly to avoid any case of an authenticated user moving from the chair and intruder trying to access the account. As far authorization is concerned, we plan to develop gesture-based clearance systems that is in-line with the terminology used by USA Department of Defense. Different hand gestures made by an authenticated system will take as different commands to switch the mode and let the user access his data objects whose sensitivity is lesser than the user mode. This can be helpful where in user must switch the roles quickly on seeing someone approaching his desktop personally.

description: The evergrowing need to understand and engineer biological and biochemical mechanisms has led to the emergence of the field of nanobiosensing. Structural DNA nanotechnology, encompassing methods such as DNA origami and single-stranded tiles, involves the base pairing-driven knitting of DNA into discrete one-, two-, and three-dimensional shapes atnanoscale. Such nanostructures enable the versatile design and fabrication of nanobiosensors. These systems benet from DNA's programmability, inherent biocompatibility, and the ability to incorporate and organize functional materials such as proteins and metallic nanoparticles. A mix-and-match taxonomy and approach to designing nanobiosensors using structural DNA nanotechnology, in which the choices of bioanalyte and transduction mechanism are fully independent of each other has led to opportunities for greater complexity and programmability of these systems.Despite its potential to transform diagnostics, therapeutics, nanomachines, nanosensing, and molecular computation, there are presently no consumer-directed or medical products on the market made from structural DNA nanotechnology. The broader impact of structural DNA nanotechnology has been limited due to restrictions imposed by the scope of DNA as a nanomaterial. Its dependency on high salt concentrations for structural stabilization, susceptibility to enzymatic degradation and denaturation in organic solvents limit the applications of unprotected DNA nanostructures.In this work, we study the tuneable actuation of twisted, micron-scale DNA nanotubes using a non-scaffolded approach. This study highlights in part, the capability for reversible conformational changes by chiral DNA microstructures which is an emerging area of active research. Additionally, the work would also highlight the need for the development of stiffermolecular constructs for active architectures at the mesoscale. This work then demonstrates subsequently, the development of nanomaterials made from gamma-modified peptide nucleic acids (gPNA) - a synthetic DNA mimic as a building material for nanofibers. Specifically, gPNA show the capability to enable formation of complex, self-assembling nanostructures in select polar aprotic organic solvent mixtures. We explore and highlight the role of conventional surfactants, solvent conditions and strand substitution with DNA in tuning the morphology of the self-assembled nanostructures. This work thereby introduces a science of gPNA nanotechnology. Finally, we engineer improvementsto the self-assembly process of gPNA to robustly form nanofibers at constant temperatures in as little as 30 minutes. We achieve this by exploring the (L)-serine -modification in the peptide backbone at high densities.
Character displacement and variability in lacustrine sympatric and allopatric Dolly Varden (Salvelinus malma) populations

description: The object of this study was to investigate character displacement (Brown and Wilson, 1956) and reduction of phenotypic variability with reduction in niche width (Van Valen, 1965). Dolly Varden from one sympatric (Loon Lake) and two allopatric (Dickson and Foley Lake) populations were compared. Field studies showed that the niche width of sympatric Dolly Varden was less than that of allopatric Dolly Varden owing to food and spatial segregation, confirming results of an earlier study (Andrusak and Northcote, 1971). Character displacement was evident in pyloric caeca numbers and in certain behavioural responses (spatial distribution and feeding) observed in the laboratory. These were accompanied by reduced variability, also apparent in length distributions within year classes, in the sympatric population compared with an allopatric population (Dickson Lake). However, character displacement and reduced variability could not be demonstrated for most morphometric characters, presumably because of the complexity of growth processes involved. Effects of overlapping adjacent year classes and of continuous growth of fish body parts (in contrast to comparable studies with birds) obscured interpretation of such characteristics.

description: We study differential-difference equation of the form $$ \frac{d}{dx}t(n+1,x)=f(t(n,x),t(n+1,x),\frac{d}{dx}t(n,x)) $$ with unknown $t(n,x)$ depending on continuous and discrete variables $x$ and $n$. Equation of such kind is called Darboux integrable, if there exist two functions $F$ and $I$ of a finite number of arguments $x$, $\{t(n\pm k,x)\}_{k=-\infty}^\infty$, ${\frac{d^k}{dx^k}t(n,x)}_{k=1}^\infty$, such that $D_xF=0$ and $DI=I$, where $D_x$ is the operator of total differentiation with respect to $x$, and $D$ is the shift operator: $Dp(n)=p(n+1)$. Reformulation of Darboux integrability in terms of finiteness of two characteristic Lie algebras gives an effective tool for classification of integrable equations. The complete list of Darboux integrable equations is given in the case when the function $f$ is of the special form $f(u,v,w)=w+g(u,v)$.

description: Der Blatthornkäfer Popillia japonica (Japankäfer) spielt in seinem heimischen Ökosystem in Japan eine eher unauffällige Rolle. Vor etwa 100 Jahren wurde er jedoch in die USA eingeschleppt. Da dort natürliche Gegenspieler weitgehend fehlen, breitete er sich massiv aus und verursacht bis heute hohe ökonomische Verluste. In Europa wurde der Käfer in der 70er Jahren auf den Azoren entdeckt. Im Jahr 2014 reiste er vermutlich als „Tramper“ via Luftverkehr in die Lombardei (Italien) und verursacht dort gravierende Schäden. Um eine weitere Ausbreitung zu verhindern, wurde der Japankäfer in der EU und somit auch in Deutschland als Quarantäneschädling eingestuft. Es gelten besondere Regelungen und Vorsichtsmaßnahmen, um ein Einschleppen zu verhindern und einem Ansiedeln sowie Ausbreiten vorzubeugen (Pflanzengesundheitsverordnung).

description: The role of academic emotions in influencing students' learning experiences and outcomes is increasingly recognized, particularly as artificial intelligence (AI) becomes more integrated into educational settings. Understanding how these emotions interact with AI is essential for enhancing student performance.While existing research has established the general effects of academic emotions on performance, the specific impacts of AI on these emotions and their subsequent influence on academic outcomes remain under-explored. This study employs a mixed-methods approach, involving 120 translation students from three universities that utilize AI-driven learning systems. Participants completed a modified Academic Emotions Questionnaire and provided qualitative reports detailing their experiences with AI tools. Their academic performance was collected. Regression analysis reveals that positive emotions—anticipation, joy, and curiosity—significantly predict academic performance in AI-enhanced environments. Additionally, topic modeling of students' reports identifies key themes such as reduced cognitive load , access for academic resources, immediate feedback and personalized learning, indicating that AI tools positively influence academic emotions and performance. The findings underscore the importance of designing AI systems that foster positive academic emotions, thereby improving educational outcomes. This research highlights the need for further exploration into the emotional dynamics of AI in education to support both cognitive and emotional development in students.
Solar-Cycle Characteristics Examined in Separate Hemispheres: Phase, Gnevyshev Gap, and Length of Minimum

description: Research results from solar-dynamo models show the northern and southern hemispheres may evolve separately throughout the solar cycle. The observed phase lag between the hemispheres provides information regarding the strength of hemispheric coupling. Using hemispheric sunspot-area and sunspot-number data from Cycles 12 - 23, we determine how out of phase the separate hemispheres are during the rising, maximum, and declining period of each solar cycle. Hemispheric phase differences range from 0 - 11, 0 - 14, and 2 - 19 months for the rising, maximum, and declining periods, respectively. The phases appear randomly distributed between zero months (in phase) and half of the rise (or decline) time of the solar cycle. An analysis of the Gnevyshev gap is conducted to determine if the double-peak is caused by the averaging of two hemispheres that are out of phase. We confirm previous findings that the Gnevyshev gap is a phenomenon that occurs in the separate hemispheres and is not due to a superposition of sunspot indices from hemispheres slightly out of phase. Cross hemispheric coupling could be strongest at solar minimum, when there are large quantities of magnetic flux at the Equator. We search for a correlation between the hemispheric phase difference near the end of the solar cycle and the length of solar-cycle minimum, but found none. Because magnetic flux diffusion across the Equator is a mechanism by which the hemispheres couple, we measured the magnetic flux crossing the Equator by examining magnetograms for Solar Cycles 21 - 23. We find, on average, a surplus of northern hemisphere magnetic flux crossing during the mid-declining phase of each solar cycle. However, we find no correlation between magnitude of magnetic flux crossing the Equator, length of solar minima, and phase lag between the hemispheres.

description: We study the correlators of bulk and defect half-BPS operators in $\mathcal{N}=4$ super Yang-Mills theory with a Maldacena-Wilson line defect, focusing on the case involving one bulk and two defect local operators. We analyze the non-perturbative constraints on these correlators, which include a topological sector, pinching and splitting limits, as well as a compatibility with expanding in superconformal blocks. Using these constraints, we compute a variety of bulk-defect-defect correlators up to next-to-leading order at weak coupling, and observe that transcendental terms cancel. Additionally, we study the two leading terms in the strong-coupling regime, and present partial results for the next-to-next-to-leading order.

description: Riassunto – Il paper intende valorizzare l’apporto della prospettiva sociomateriale nei percorsi di consulenza pedagogica a scuola, sia enucleandone i presupposti teorici e metodologici di fondo, sia facendo riferimento a titolo esemplificativo ad alcune pratiche consulenziali. Il paradigma sociomateriale consente di focalizzare lo sguardo sulla materialità dell’educazione, riconoscendone il ruolo attivo nelle pratiche educative e formative. Tematizzare la materialità in azione a scuola, nel percorso consulenziale, permette di osservare da una diversa angolatura l’accadere educativo, restituendo una complessità spesso sfuggente e fornendo strumenti interpretativi per leggerla, pensarla e affrontarla. In quest’ottica, la prospettiva sociomateriale, specialmente se impiegata in combinazione con altri approcci, offre l’opportunità di considerare significato e materialità in un quadro d’insieme, costruendo una cornice epistemologica in grado di intercettare la complessità del fare scuola.
