description: Die Industriestadt Nowa Huta – 1949 in der Nachbarschaft von Krakau gegründet – ist ein Sinnbild des Stalinismus in Ostmitteleuropa. Geplant als Heimstätte für die Arbeiter der gigantischen Lenin-Stahlhütte, verkörperte sie das Ziel von Polens kommunistischen Machthabern, eine neue Gesellschaftsordnung zu schaffen. Durch die Arbeit in den Stahlwerken und das Leben in der nach ideologischen Gesichtspunkten geplanten Stadt sollten Nowa Hutas Bewohner zu neuen Menschen geformt werden. Anne Applebaum hat Nowa Huta, neben Stalinstadt in der DDR und Sztálinváros in Ungarn, als umfassendsten Versuch ostmitteleuropäischer Kommunisten bezeichnet, eine „echte totalitäre Zivilisation" zu schaffen. [1] In ihrer Kultur-, Alltags- und Sozialgeschichte Nowa Hutas zeichnet Katherine Lebow ein etwas anderes Bild von Polens sozialistischer Musterstadt. Dabei unterschlägt sie nicht, dass Repression und Ideologie für den Alltag der polnischen Gesellschaft jener Zeit wichtig waren. Im Anschluss u.a. an Jochen Hellbeck möchte sie jedoch die gelebte Alltagsideologie der Bewohner Nowa Hutas studieren. Während Hellbeck in seinen Studien des sowjetischen Stalinismus der 1930er Jahre Ideologie jedoch als allumfassend und hegemonial versteht, zeigt L. auf, dass die Aneignung ideologischer Inhalte soziale Dynamiken in Gang setzte, die die Herrschenden nicht kontrollieren konnten. [2] Und es waren nach ihrer Auffassung die dadurch entstandenen Arbeitertradition und Ideale, die Nowa Huta – neben anderen Faktoren – zu einer Hochburg der Solidarność in den 1980er Jahren machte.

description: Kilka miesięcy temu wybrałam się niebieskim tramwajem z Krakowa do Nowej Huty. Na Placu Centralnym im. Ronalda Regana było niedzielnie, pusto i spokojnie. Mój niedzielny spacer miał prowadzić do bramy kombinatu, niegdyś im. Lenina. Po drodze zwiodły mnie jednak kwitnące wszędzie malwy, klomby i aleje wysadzane drzewami. W zieleń harmonijnie wrastały osiedlowe, nie za wysokie domy. Zatrzymałam się na dłużej w tym mieście-ogrodzie, śledząc ocienione chodniki i plamy słońca. Na tym rozpoczęła i zakończyła się moja edukacyjna wycieczka do Nowej Huty, wizytówki Planu Sześcioletniego i symbolu stalinowskiej industrializacji. Kolor zielony zupełnie przesłonił czerwono-szary odcień zapamiętanych przez lata obrazków, pamięciowych przebitek z „Człowieka z marmuru" i cytatów z „Poematu dla dorosłych" Ważyka o wytapiającej się „w węglowym czadzie i w powolnej męczarni klasie robotniczej" spod Krakowa. Tamtego dnia w Nowej Hucie najlepiej było poczuć się niedzielnym spacerowiczem. Dzięki badaniom nad codziennością i historią społeczną PRL, historii mówionej i publikacji wielu źródeł historycznych, obraz powojennej Polski już od dawna przestał być jednolity. Wielość perspektyw i prób znalezienia nowego języka mówienia o komunizmie jest uderzająca, nawet jeśli w publicznym dyskursie wciąż najlepiej sprzedają się proste tezy i wydarzeniowa, ahistoryczna wizja przeszłości.

description: Remembering Occupied Warsaw investigates ethnic Poles' memory of the Nazi occupation of Warsaw during World War II based on ethnographic fieldwork and life history interviews. Tucker conducted her research in Żoliborz during the late 1990s with follow-up visits over several summers through 2008. The author wrote on a historical topic, but the research methods are those of a cultural anthropologist: fieldwork, participant observation, and in-depth life interviews. By examining her respondents' narratives of the outbreak of war, the Nazi occupation and the postwar recovery of Warsaw, Tucker aims to find out how this past has shaped attitudes and actions in contemporary Poland and to explore the relationship between memory, narrative, trauma, and place. Her attention to the private experiences of the inhabitants of Warsaw will add to historians' knowledge and understanding of the occupation of the Polish capital. While the politics of wartime destruction are well-known, this book permits an understanding of the occupation as an everyday phenomenon.

description: This book by a sociologist with historical interest is an “explanatory monograph" of the nation-making process in Żmiąca, a small mountainous village located in south-eastern Poland. In this book, the author seeks to explain the apparent paradox of Żmiąca inhabitants' present idea of the Polish nation being “eternal," while in the nineteenth century, and even up to World War I their forefathers associated “Poles" with “Masters" (panowie) and treated them as alien and dangerous. Łuczewski selected this village because it was an object of a study done by a noted Polish historian Franciszek Bujak in 1903 and of another study by sociologist Zbigniew T. Wierzbicki in 1963. Łuczewski and his students conducted their own field work there in the first decade of the present century. The author, well-familiar with the on-going general debate on nation-making processes, ambitiously sets himself a task of explaining his case in the light of an “integral theory" of nation (an approach rather than a theory in this reviewer's opinion). This he formulates in polemics with the primordial theory (nations are eternal), the modernist theory (nations are creations of modernity), the ethno-symbolic theory (while nations are creations of modernity, they are also communities of culture) and the constructivist theory (nations do not exist, what exist are their representations). His own explanatory approach, building on the critical reading of these theories, consists on singling out the creators and the recipients of national ideologies. The creators may be as well intellectuals as parents telling stories to their children. The reception depends on the social context and on the adequacy of an ideology's message to its recipients' interests.
The life-history of the sand crab Hippa cubensis saussure living on a small island
Creators: name: Hanson, Arthur John
Publisher: name: University of British Columbia
Year: 2011

description: The closely related sand crabs Hippa and Emerita both inhabit the intertidal zone of tropical sandy beaches but Emerita is absent from many oceanic islands while Hippa is absent from most mainland coasts. The distribution patterns are explained by comparing the life-history of H. cubensis, living in the West Indies, with published information on Emerita species. Size distributions and beach habits of the 2 genera were similar and differences in egg production and larval development times are considered to be temperature-dependent and not generic differences. A preference of Hippa for coarse sand beaches, found mainly on islands, partly accounts for the distribution of this genus. The preference is accounted for by the absence of an effective respiratory tube and behavioral adaptations traced to feeding habits. Hippa appears to be relatively stenothermal, which would account for its absence from warm temperate areas occupied by Emerita. The distribution patterns of Emerita are not readily explained. The possibilities of predation of Emerita on extremely light or dark sand, as found on islands or predation of young Emerita by Hippa are considered.

description: Let $G$ be a finite group and $M(G)$ be the subgroup of $G$ generated by all non-central elements of $G$ that lie in the conjugacy classes of the smallest size. Recently several results have been proved regarding the nilpotency class of $M(G)$ and $F(M(G))$, where $F(M(G))$ denotes the Fitting subgroup of $M(G)$. We prove some conditional results regarding the nilpotency class of $M(G)$.

Hermitian-Yang-Mills equations and pseudo-holomorphic bundles on nearly Kaehler and nearly Calabi-Yau twistor 6-manifolds

description: We consider the Hermitian-Yang-Mills (HYM) equations for gauge potentials on a complex vector bundle E over an almost complex manifold X^6 which is the twistor space of an oriented Riemannian manifold M^4. Each solution of the HYM equations on such X^6 defines a pseudo-holomorphic structure on the bundle E. It is shown that the pull-back to X^6 of any anti-self-dual gauge field on M^4 is a solution of the HYM equations on X^6. This correspondence allows us to introduce new twistor actions for bosonic and supersymmetric Yang-Mills theories. As examples of X^6 we consider homogeneous nearly Kaehler and nearly Calabi-Yau manifolds which are twistor spaces of S^4, CP^2 and B_4, CB_2 (real 4-ball and complex 2-ball), respectively. Various explicit examples of solutions to the HYM equations on these spaces are provided. Applications in flux compactifications of heterotic strings are briefly discussed.

description: To date, stories and suggestions appear in all kinds of popular and pseudo-scientific media that push forward the possibility of circumventing gravity in all kinds of possible and impossible ways. It is a continuation of a deliberately well-programmed storyline by those who benefit from it, and which intuitively responds to the age-old ideas that the gods and strange creatures came from outer space with vehicles which silently and without smoke descended from the heavens. This storyboard was magnified after the Second World War and taken to a completely different level. The period between the Interbellum and the end of the Second World War was one in which again a tremendous scientific boom took place, and many of new groundbreaking ideas brought about a revolutionary change, not only in the social, economic and political sphere but also and especially in the field of aviation and rocket science. Strange devices with thundering engines began to fill the air and at exceptional moments even stranger apparatuses were seen, combining maneuverability and silent flight, seemingly defying gravity. In the next pages I will give a new meaning to gravity and why gravity is a force that cannot be set aside, it will always be a determining factor here on earth and in the universe. More than that, it gives a different fresh perspective on the nature of gravitational waves and the expansion of the universe. In the aftermath of these new insights, it was interesting to learn how in the early years of the rise of electricity, attempts were made to find ways to get around gravity. It was the perfect reason to go on a quest of my own knowing that the underlying truth is that there is no possibility to get around the fundamentals of gravity. Still, there are aerial phenomena that seem to defy gravity… so what's going on? The challenge was to find the answer to the question “is there really a way out of this dilemma?” THE RESPONSE TO THAT QUESTION WAS MIND BLOWING, NOT ONLY GAVE IT AN INSIGHT IN THE WAY THOSE “STRANGE DEVICES” ARE FUNCTIONING BUT THERE WAS ALSO THAT SURPRISE THAT IT IS POSSIBLE TO GENERATE ENERGY WITHOUT THE USE OF FOSSIL FUEL.

description: Il presente volume nasce con l’ambizioso obiettivo di comprendere come e perché l’impresa cooperativa costituisca uno strumento valido per la costruzione e la gestione condivisa dei beni comuni. Per raggiungere questo obiettivo, al volume hanno contribuito diciannove autori tra accademici e cooperatori. Il libro è composto da tre sezioni: ‘identità, valori ed obiettivi’, ‘buone pratiche e nuovi orizzonti cooperativi’ e ‘startup cooperative’. Come nel caso del ‘The Co-operator’ di King, che creò una guida pratica e teorica per i cooperatori del futuro, il volume aspira a riaprire un dialogo tra gli accademici, impegnati nello studio dell’impresa cooperativa, ed i cooperatori. Un dialogo all’insegna del bene comune.
Non-equilibrium steady state in a periodically driven Kondo model

description: We investigate the Kondo model with time-dependent couplings that are periodically switched on and off. On the Toulouse line we derive exact analytical results for the spin dynamics in the steady state that builds up after an infinite number of switching periods. Remarkably, the algebraic long time behavior of the spin-spin correlation function remains completely unaffected by the driving. In the limit of slow driving the dynamics become equivalent to that of a single interaction quench. In the limit of fast driving one can show that the steady state cannot be described by some effective equilibrium Hamiltonian since a naive implementation of the Trotter formula gives wrong results. As a consequence, the steady state in the limit of fast switching serves as an example for the emergence of new quantum states not accessible in equilibrium.

description: A spin network is a cubic ribbon graph labeled by representations of $\mathrm{SU}(2)$. Spin networks are important in various areas of Mathematics (3-dimensional Quantum Topology), Physics (Angular Momentum, Classical and Quantum Gravity) and Chemistry (Atomic Spectroscopy). The evaluation of a spin network is an integer number. The main results of our paper are: (a) an existence theorem for the asymptotics of evaluations of arbitrary spin networks (using the theory of $G$-functions), (b) a rationality property of the generating series of all evaluations with a fixed underlying graph (using the combinatorics of the chromatic evaluation of a spin network), (c) rigorous effective computations of our results for some $6j$-symbols using the Wilf-Zeilberger theory, and (d) a complete analysis of the regular Cube $12j$ spin network (including a non-rigorous guess of its Stokes constants), in the appendix.

description: The computational complexity of time-dependent perturbation theory is well-known to be largely combinatorial whatever the chosen expansion method and family of parameters (combinatorial sequences, Goldstone and other Feynman-type diagrams...). We show that a very efficient perturbative expansion, both for theoretical and numerical purposes, can be obtained through an original parametrization by trees and generalized iterated integrals. We emphasize above all the simplicity and naturality of the new approach that links perturbation theory with classical and recent results in enumerative and algebraic combinatorics. These tools are applied to the adiabatic approximation and the effective Hamiltonian. We prove perturbatively and non-perturbatively the convergence of Morita's generalization of the Gell-Mann and Low wavefunction. We show that summing all the terms associated to the same tree leads to an utter simplification where the sum is simpler than any of its terms. Finally, we recover the time-independent equation for the wave operator and we give an explicit non-recursive expression for the term corresponding to an arbitrary tree.

description: We report the results of a mm-wave molecular line survey of the nearby (D ~ 70 pc), 12 Myr-old system V4046 Sgr -- a tight (9 R_sun separation), short-period (2.42 day) binary with nearly equal component masses of ~0.9 M_sun -- conducted with the 30 m telescope of the Institut de Radio Astronomie Millimetrique (IRAM). We detected rotational transitions of 12CO 13CO, HCN, CN, and HCO+. The double-peaked CO line profiles of V4046 Sgr are well fit by a model invoking a Keplerian disk with outer radius of ~250 AU that is viewed at an inclination i = 35 degrees. We infer minimum disk gas and dust masses of ~13 and ~20 Earth masses from the V4046 Sgr CO line and submm continuum fluxes, respectively. The actual disk gas mass could be much larger if the gas-phase CO is highly depleted and/or 13CO is very optically thick. The overall similarity of the circumbinary disk of V4046 Sgr to the disk orbiting the single, ~8 Myr-old star TW Hya -- a star/disk system often regarded as representative of the early solar nebula -- indicates that gas giant planets are likely commonplace among close binary star systems. Given the relatively advanced age and proximity of V4046 Sgr, these results provide strong motivation for future high-resolution imaging designed to ascertain whether a planetary system now orbits its twin suns.

description: The stellar (n,gamma) cross section of 40Ca at kT=25 keV has been measured with a combination of the activation technique and accelerator mass spectrometry (AMS). This combination is required when direct off-line counting of the produced activity is compromised by the long half-life and/or missing gamma-ray transitions. The neutron activations were performed at the Karlsruhe Van de Graaff accelerator using the quasistellar neutron spectrum of kT=25 keV produced by the 7Li(p,n)7Be reaction. The subsequent AMS measurements were carried out at the Vienna Environmental Research Accelerator (VERA) with a 3 MV tandem accelerator. The doubly magic 40Ca is a bottle-neck isotope in incomplete silicon burning, and its neutron capture cross section determines the amount of leakage, thus impacting on the eventual production of iron group elements. Because of its high abundance, 40Ca can also play a secondary role as "neutron poison" for the s-process. Previous determinations of this value at stellar energies were based on time-of-flight measurements. Our method uses an independent approach, and yields for the Maxwellian-averaged cross section at kT=30 keV a value of 30 keV= 5.73+/-0.34 mb.

description: We present the results of hydrodynamical simulations of gamma-ray burst jets propagating through their stellar progenitor material and subsequently through the surrounding circumstellar medium. We consider both jets that are injected with constant properties in the center of the star and jets injected with a variable luminosity. We show that the variability properties of the jet outside the star are a combination of the variability injected by the engine and the variability caused by the jet propagation through the star. Comparing power spectra for the two cases shows that the variability injected by the engine is preserved even if the jet is heavily shocked inside the star. Such shocking produces additional variability at long time scales, of order several seconds. Our findings suggest that the broad pulses of several seconds duration typically observed in gamma-ray bursts are due to the interaction of the jet with the progenitor, while the short-timescale variability, characterized by fluctuations on time scales of milliseconds, has to be injected at the base of the jet. Studying the properties of the fast variability in GRBs may therefore provide clues to the nature of the inner engine and the mechanisms of energy extraction from it.

description: We present a categorification of four mutation finite cluster algebras by the cluster category of the category of coherent sheaves over a weighted projective line of tubular weight type. Each of these cluster algebras which we call tubular is associated to an elliptic root system. We show that via a cluster character the cluster variables are in bijection with the positive real Schur roots associated to the weighted projective line. In one of the four cases this is achieved by the approach to cluster algebras of Fomin-Shapiro-Thurston using a 2-sphere with 4 marked points whereas in the remaining cases it is done by the approach of Geiss-Leclerc-Schroer using preprojective algebras.

How happy is your web browsing? A model to quantify satisfaction of an Internet user, searching for desired information

description: We feel happy when web-browsing operations provide us with necessary information; otherwise, we feel bitter. How to measure this happiness (or bitterness)? How does the profile of happiness grow and decay during the course of web-browsing? We propose a probabilistic framework that models evolution of user satisfaction, on top of his/her continuous frustration at not finding the required information. It is found that the cumulative satisfaction profile of a web-searching individual can be modeled effectively as the sum of random number of random terms, where each term is mutually independent random variable, originating from 'memoryless' Poisson flow. Evolution of satisfaction over the entire time interval of user's browsing was modeled with auto-correlation analysis. A utilitarian marker, magnitude of greater than unity of which describe happy web-searching operations; and an empirical limit that connects user's satisfaction with his frustration level - are proposed too. Presence of pertinent information in the very first page of a web-site and magnitude of the decay parameter of user satisfaction (frustration, irritation etc.), are found to be two key aspects that dominate web-browser's psychology. The proposed model employed different combination of decay parameter, searching time and number of helpful web-sites. Obtained results are found to match the results from three real-life case-studies.
Studies on the rehydration of irradiated freeze-dried beef
Creators: name: Ni, Yeng-Wei
Publisher: name: University of British Columbia
Year: 2011

description: The total water uptake, rate of water uptake, extract release volume and maximum shear force were measured on a series of samples of irradiated freeze-dried beef. Forty seven pieces of round steak (2.5 cm x 2.5 cm x 10.4 cm or 1" x 1" x 4") were irradiated at one, three and five megarad. The control samples were not irradiated. Half of the samples were irradiated when fresh, and the other half were irradiated after freeze drying. This procedure has been defined as the "fresh-dry" irradiation sequence throughout the report. The samples were frozen in an air blast at two temperatures (-22.2°C and -56.1°C). Freeze-drying was carried out below 300 microns of Hg and a maximum shelf temperature of 15.6°C (60°F). There appears to be three phases of water uptake: 1) A very rapid, almost instantaneous, absorption. 2) A more gradual uptake (called Part.1 in the report). 3) A relatively slow asymptotic approach to an equilibrium condition (Part 2). These two last phases are shown to be straight lines when the logarithm of the water uptake is plotted against the logarithm of the immersion time. Irradiation level has no significant effect on the final water content or on the slow asymptotic absorption (Part 2) or the extract release volume, but has a significant effect on the gradual water uptake (Part 1) and on the shear press force. Fresh-dry irradiation sequence (and freezing rate) have a significant effect on the total water uptake and on the slow asymptotic water (Part 2) uptake, but not on the gradual water uptake (Part 1), or on the extract release volume or on the shear press forces. Freezing rates have a significant effect on the total water uptake, but not on the slow asymptotic water uptake (Part 2), on the gradual water uptake (Part 1), on the extract release volume or on the shear press forces. The highest total water uptake was found for the meat irradiated when fresh, and slow frozen at -2 2.2°C. The mechanism of the gradual absorption appears to follow a phenomena of water flow, as evidenced by the straight line relationship found in the plots of logarithm water uptake versus logarithm immersion time.

description: The rapid adoption of robotic surgery worldwide has been attributed to its perceived surgical and patient benefits. Little attention however has been given to the effect of introduction of a new technology, surgeon-team separation, or the large-sized equipment on staff experiences and theatre dynamics.The first aim of this thesis was to review the uptake and outcomes of robotic gynaecological surgery in England (2006-2018) based on Hospital Episodes Statistics. 527,217 elective gynaecological procedures were performed, 4384 (0.83%) of which were performed robotically. There was a gradual rise in the uptake of robotic surgery overall, but marked geographical variation across England. Clinical outcomes were comparable to those reported in other countries.My second aim was to explore staff experiences in robotic theatres using semi-structured interviews and participant observations. Robotic procedures were observed at two tertiary hospitals and laparoscopic/ open procedures were added for comparison. Observation field notes were taken contemporaneously and the interviews were audio recorded and transcribed verbatim. Qualitative analysis was conducted via grounded theory approach using NVIVO12. Twenty-nine participants were recruited to the study and 134 hours of observation were completed across urology, gynaecology and colorectal surgery.Data analysis identified major concepts pertaining to the robotic team, theatre environment and staff emotions. Higher conceptual analysis proposed a “Robotic Proficiency Theory”, where major elements pertaining to quality patient care included collaborative supportive leadership, the robotic team, robotic processes and optimal robotic performance. While this theory may also apply to other surgical settings, its elements are particularly important within the robotic setting due to the introduction of new technology, surgeon-team separation and large-sized equipment.Clinically, the proposed model sets a framework to guide introduction or assessment of a robotic surgical programme. From a research perspective, this model will need to be tested within other settings utilising the newer robotic platforms.
Intermediary carbohydrate and amino acid metabolism in clostridium perfringens type A

Publisher: name: University of British Columbia

description: Clostridium perfringens was found to produce marked changes in its environment during growth. Decrease in electropotential, as well as decrease in pH, correlated with resumption of cellular activity on transfer into a defined medium. Eight amino acids were found to be essential for growth, while the remaining ten amino acids fell into four categories according to the degree of independence the organism had with respect to them. The form of the B-6 vitamin present in the medium had an important influence on the synthesis of several amino acids. The synthesis and degradation of amino acids was investigated further. The enzyme systems involved in these functions could be described as three major groups: those enzymes involved in synthesis of amino acids and amino compounds from glucose, the enzymes responsible for the interconversion of threonine, glycine and serine, and those involved with glutamic acid, proline and arginine metabolism. Uptake of amino acids by both resting and growing cell suspensions was found to be by an efficient, non-energy dependent diffusion mechanism. During growth approximately 5% of the exogenously supplied glucose was assimilated into cell material, primarily as cell wall or nucleic acid components. Molar growth yields from glucose were found to be significantly greater than the theoretical value. The calculated ratio of reduced to oxidized coenzymes indicated a characteristic trend over the logarithmic and stationary growth phases. The relationship between amino acid metabolism, glucose dissimilation and assimilation, and overall metabolite and energy balances has been discussed with a view to understanding the extent of control and influence C. perfringens has on its own metabolic functions and on its environment.

description: In this paper we calculate the effect of the inclusion of exotic smooth structures on typical observables in Euclidean quantum gravity. We do this in the semiclassical regime for several gravitational free-field actions and find that the results are similar, independent of the particular action that is chosen. These are the first results of their kind in dimension four, which we extend to include one-loop contributions as well. We find these topological features can have physically significant results without the need for additional exotic physics.

Predicting positive and negative change in expeditioners at 2-months and 12-months post Antarctic employment

description: Extreme weather conditions and geographical isolation are among many factors that render Antarctica a challenging environment for employees to sustain optimum levels of functioning. However, challenges associated with Antarctic employment can extend beyond their time “on the ice” to influence post-Antarctic adjustment. The current study investigated predictors of positive and negative psychological change reported by expeditioners 2 and 12 months post-return from “the ice” to identify factors that influence adjustment following Antarctic employment. The sample comprised 383 (277 male, 106 female) expeditioners, recruited from Australian Antarctic program between years 2005 and 2010. Scores on the Changes in Outlook Questionnaire (CiOQ) were examined at 2 and 12 months post-return. Results indicated that positive and negative psychological change at both time points was predicted by pre-departure and post-return factors, not by experiences whilst “on the ice”. It was also identified that predictors of positive and negative change differed as a function of relationship status. This indicates that expeditioners would benefit from proactive prevention and intervention strategies prior to departure and upon return from their employment, not simply whilst working in Antarctica. Additionally, the nature of such interventions needs to consider relationship status as a factor that can influence post-return adaptation and functioning.
Star formation in M33: multiwavelength signatures across the disk

description: Aims. We use different tracers, such as Ha, ultraviolet (UV), and infrared (IR) emissions at various wavelengths, to study the dust and star-formation (SF) conditions throughout the disk of M33. Methods. We derive the radial distribution of dust, of the old and young stellar population using Spitzer and GALEX data, complemented by ground-based optical data and available surveys of atomic and molecular gas. We separate the contribution of discrete sources to the IR brightness from the diffuse emission. Results. At 8 and 24 um, discrete sources account for 40% of the IR emission in the innermost 3 kpc, and for 20% further out. We find that stochastic emission from very small grains in the diffuse interstellar medium accounts for only 10% of the diffuse 24 um emission, and that dusty circumstellar shells of unresolved, evolved AGB stars (carbon stars) are a viable alternative. The 8 um profile suggests that PAH emission declines faster with radius than the dust continuum. In annular regions, 0.24 kpc wide, we find a mean extinction value for stellar continuum AV = 0.25 mag with a weak dependence on radius, consistent with the shallow metallicity gradient observed. Dust opacity derived from the 160 um emission decreases instead by a factor 10 from the center to edge of the SF disk. Conclusions. Using extinction corrected UV and Ha maps we find the global SF rate in M33, over the last 100 Myr, to be 0.45 +- 0.10 M yr-1. FIR (far-IR) and TIR (total-IR) luminosities can trace SF even though a high conversion factor is required to recover the effective rate. If carbon stars are powering the diffuse 24 um emission in M33 this can trace star formation 1 Gyr ago and provide a more complete view of the SF history of the galaxy. [abridged]

description: A simple method for some class of inverse obstacle scattering problems is introduced. The observation data are given by a wave field measured on a known surface surrounding unknown obstacles over a finite time interval. The wave is generated by an initial data with compact support outside the surface. The method yields the distance from a given point outside the surface to obstacles and thus more than the convex hull.

description: We developed a scheme for evaluating the size of the largest connected subnetwork (giant component) in random networks and the percolation threshold when sites (nodes) and/or bonds (edges) are removed from the networks based on the cavity method of statistical mechanics of disordered systems. An advantage of our scheme is the capability of handling targeted attacks on sites/bonds in the presence of degree correlations beyond naive analyses on random failures (crashes) in networks of no degree correlations. We apply our scheme particularly to random networks of bimodal degree distribution (two-peak networks), which have been proposed in earlier studies as robust networks against random failures of site and/or targeted attacks on sites, and show that the correlations among degrees affect a network's robustness against targeted attacks on sites or bonds non-trivially depending on details of network configurations.

Motivation and Academic Resilience in University Students: The Moderating Role of Age
Creators: name: Phair, JK
Publisher: name: University Of Tasmania

Subjects: Educational psychology

description: University students face ongoing challenges, pressure and stressors throughout the course of their studies. Academic resilience is defined as students’ capacity to cope with chronic stressors that pose a major threat to long-term academic success (Martin & Marsh, 2009). The present study examined the effect of five motivational predictors of academic resilience proposed by Martin and Marsh (self-efficacy, persistence, planning, low uncertain control and low anxiety) in a sample of university students. The moderating role of age on this relationship was investigated. Participants comprised 466 undergraduate psychology students (337 females, Mage = 25.11) who completed a brief version of the Motivation and Engagement Scale University-College (MES-UC) and Academic Resilience Scale (ARS). Results showed that adaptive components of the MES-UC scale were positively related to academic resilience. The moderating effect of age in these was significant for selfefficacy, planning and persistence, whereby this effect was more pronounced for older students. These results suggest that interventions to increase academic resilience in university students should focus on enhancing adaptive aspects of motivation and behavioural engagement, and this is particularly important for older students.
