description: We construct empirical models of star-forming galaxy evolution assuming that individual galaxies evolve along well-known scaling relations between stellar mass, gas mass and star formation rate following a simple description of chemical evolution. We test these models by a comparison with observations and with detailed Magneticum high resolution hydrodynamic cosmological simulations. Galaxy star formation rates, stellar masses, gas masses, ages, interstellar medium and stellar metallicities are compared. It is found that these simple lookback models capture many of the crucial aspects of galaxy evolution reasonably well. Their key assumption of a redshift dependent power law relationship between galaxy interstellar medium gas mass and stellar mass is in agreement with the outcome of the complex Magneticum simulations. Star formation rates decline towards lower redshift not because galaxies are running out of gas, but because the fraction of the cold ISM gas, which is capable of producing stars, becomes significantly smaller. Gas accretion rates in both model approaches are of the same order of magnitude. Metallicity in the Magneticum simulations increases with the ratio of stellar mass to gas mass as predicted by the lookback models. The mass metallicity relationships agree and the star formation rate dependence of these relationships is also reproduced. We conclude that these simple models provide a powerful tool for constraining and interpreting more complex models based on cosmological simulations and for population synthesis studies analyzing integrated spectra of stellar populations.

description: The quantum characteristics of sum-frequency process in an optical cavity with an input signal optical beam, which is a half of entangled optical beams, are analyzed. The calculated results show that the quantum properties of the signal beam can be maintained after its frequency is conversed during the intracavity nonlinear optical interaction. The frequency-conversed output signal beam is still in an entangled state with the retained other half of initial entangled beams. The resultant quantum correlation spectra and the parametric dependences of the correlations on the initial squeezing factor, the optical losses and the pump power of the sum-frequency cavity are calculated. The proposed system for the frequency conversion of entangled state can be used in quantum communication network and the calculated results can provide direct references for the design of experimental systems.

description: Η νόσος Alzheimer αφορά σε υψηλό ποσοστό ανθρώπων μεγάλης ηλικίας, και η αποτελεσματικότερη αντιμετώπισή της προαπαιτεί έγκαιρη διάγνωση, κάτι που δεν είναι ιδιαίτερα εύκολο διότι οι υπάρχουσες μέθοδοι απαιτούν μεγάλο αριθμό εξετάσεων, αναλύσεων και δοκιμασιών. Σημαντικό μέρος των ερευνητικών προσπαθειών έχει κατευθυνθεί προς την χρήση ηλεκτροεγκεφαλογραφημάτων γνωσιακών προκλητών δυναμικών (ERPs) ως μέσα διάγνωσης του πρώτου σταδίου της νόσου, το οποίο ονομάζεται ήπια νοητική απόπτωση (MCI). Προς την κατεύθυνση αυτή, στη παρούσα μελέτη διερευνήθηκε η δυνατότητα χρήσης τεχνικών ψηφιακής επεξεργασίας σήματος, εξαγωγής χαρακτηριστικών και χρήσης μηχανών ταξινόμησης με στόχο την βελτίωση της ακρίβειας των μεθόδων διάγνωσης. Διαπιστώθηκε ότι η χρήση φίλτρων, τεχνικών απόρριψης εσφαλμένων καταγραφών, η ανάλυση πρωτευουσών συνιστωσών, η χρήση μεθόδων πυρήνων, γραμμικής διαχωριστικής ανάλυσης, μετασχηματισμού κυματιδίων και οι ταξινομητές όπως οι μηχανές εδραίων διανυσμάτων, μπορούν να συμβάλλουν σε υψηλά ποσοστά ακρίβειας, ευαισθησίας και ειδικότητας, όχι μόνο χρησιμοποιώντας ως δεδομένα τα γνωστικά προκλητά δυναμικά (ERPs) αλλά και τις no-target καταγραφές (EPs).
description: Alzheimer's disease relates to a high percentage of elder people, and effective treatment requires early diagnosis, which is not an easy procedure. The reason is that existing diagnosis methods require a variety of difficult and time consuming examinations and tests. A lot of research effort has been directed toward the use of EEGs of cognitive evoked response potentials (ERPs) as a method of diagnosis of the first stage of the Alzheimer disease, called mild cognitive impairment (MCI). Towards this direction, in this study we investigated the possibility of using digital signal processing techniques, feature extraction methods and classification machines to build a reliable diagnostic tool. It was found that the combined use of filters, artifacts and outliers rejection techniques, principal components analysis, kernel methods, linear discriminant analysis, wavelet transform and classifiers such as Support Vector Machines can provide high accuracy, sensitivity and specificity, using not only cognitive event related responses (ERPs) but also the no-target evoked potentials (EPs).

description: A single crystal of 7% Fe-doped (La$_{0.7}$Pr$_{0.3}$)$_{0.65}$Ca$_{0.35}$MnO$_3$ shows up as a typical relaxor ferromagnet, where ferromagnetic metallic and charge-orbital-ordered insulating clusters coexist with controllable volume fraction by external stimuli. There, the persistent ferromagnetic metallic state can be produced by an electric-current excitation as the filamentary region, the magnetization in which is increased by ~0.4$μ_{\rm B}$ per Mn. A clear distinction from the current heating effect in a magnetic field, which conversely leads to a decrease in ferromagnetic fraction, enables us to bi-directionally switch both the magnetization and resistance by applying the voltages with different magnitudes.

description: The integration and transfer of information from multiple sources to multiple targets is a core motive of neural systems. The emerging field of partial information decomposition (PID) provides a novel information-theoretic lens into these mechanisms by identifying synergistic, redundant, and unique contributions to the mutual information between one and several variables. While many works have studied aspects of PID for Gaussian and discrete distributions, the case of general continuous distributions is still uncharted territory. In this work we present a method for estimating the unique information in continuous distributions, for the case of one versus two variables. Our method solves the associated optimization problem over the space of distributions with fixed bivariate marginals by combining copula decompositions and techniques developed to optimize variational autoencoders. We obtain excellent agreement with known analytic results for Gaussians, and illustrate the power of our new approach in several brain-inspired neural models. Our method is capable of recovering the effective connectivity of a chaotic network of rate neurons, and uncovers a complex trade-off between redundancy, synergy and unique information in recurrent networks trained to solve a generalized XOR task.

Data Management Plan

description: A Data Management Plan helps achieve optimal handling, organising, documenting and enhancing of research data. It is particularly important for facilitating data sharing, ensuring the sustainability and accessibility of data in the long-term and allowing data to be reused for future research. For the effective management of data, planning must start when research is being designed and needs to consider both how data will be managed during the research and how they will be shared afterwards. This document includes presentation slides from the Day 1 of the event.

description: We propose that the non-perturbative fragmentation functions describing the transition from a heavy quark to a heavy meson is proportional to the square of the produced meson wave function at the origin. We analyze the effects of this proposal on the number of pseudoscalar mesons compared to the number of vector mesons produced and find a good agreement with experimental data. Finally, we discuss further experimental checks for our hypothesis.

description: We describe the uniform and staggered magnetization distributions around a vacancy in a quantum critical two-dimensional S=1/2 antiferromagnet. The distributions are delocalized across the entire sample with a universal functional form arising from an uncompensated Berry phase. The numerical results, obtained using quantum Monte Carlo simulations of the Heisenberg model on bilayer lattices with up to approximately 10^5 spins, are in good agreement with the proposed scaling structure. We determine the exponent eta'=0.40 +/- 0.02, which governs both the staggered and uniform magnetic structure away from the impurity and also controls the impurity spin dynamics.

Μελετήθηκαν προβληματισμοί που αναφύονται από την χρήση των νευροτεχνολογικών εφαρμογών από ηθικοκοινωνική και νομική σκοπιά. Αρχικά εξετάσθηκε η έννοια της νευροτεχνολογίας, η εξέλιξή της ανά το πέρασμα των χρόνων και η σημερινή μορφή της, ομαδοποιούμενη σε κατηγορίες, όπου με την αναφορά παραδειγμάτων σε κάθε κατηγορία και τη συνοπτική ανάπτυξη κάθε μεθόδου επιχειρήθηκε μια εκ των έσω προσέγγιση, προκειμένου να καταστούν ευχερέστερα αντιληπτές οι έννοιες που αναφέρονται στις λοιπές σελίδες της εργασίας.

description: The aim of the thesis was to study the impact of neuroscience in modern societies. The concerns arising from the use of applications of neurotechnology were examined from an ethical, social and legal point. Initially, the concept of neurotechnology, its evolution over the years and its current form were examined, followed by a categorisation of the contemporary neurotechnological methods and by examples of each category and a brief reference for each method; a deeper approach was attempted in order to ease the understanding of the concepts mentioned in the rest pages of the thesis. Also, the study of the concept of Neuroethics followed, by giving its definition and by mentioning the various concerns that arise in the field in question. Afterwards, we examined the concept of neurolaw under the light of modern legal practice, referring to case studies that took place in various foreign countries (USA, India), as well as in our country. At this point, an attempt was made to distinguish perception models of neurotechnological applications as evidence in a court trial, based on the acceptance (and the grade of acceptance) or not of the neurotechnological applications as evidence in a court trial.

description: Black-body radiation (BBR) shift is an important systematic correction for the atomic frequency standards realizing the SI unit of time. Presently, there is a controversy over the value of the BBR shift for the primary $^{133}$Cs standard. At room temperatures the values from various groups differ at $3 \times 10^{-15}$ level, while the modern clocks are aiming at $10^{-16}$ accuracies. We carry out high-precision relativistic many-body calculations of the BBR shift. For the BBR coefficient $β$ at $T=300K$ we obtain $β=-(1.708\pm0.006) \times 10^{-14}$, implying $6 \times 10^{-17}$ fractional uncertainty. While in accord with the most accurate measurement, our 0.35%-accurate value is in a substantial, 10%, disagreement with recent semi-empirical calculations. We identify an oversight in those calculations.

A course for caregivers : group work as an intervention with family caregivers of hospitalized elderly
Creators: name: Book, Elaine Susan
Publisher: name: University of British Columbia
Year: 2009

description: The objective of this study was to examine the effects of a short-term support group on the reported stress of family caregivers of hospitalized elderly. In addition, it was designed to provide descriptive information on caregiver stress, the caregiving experience and the factors that influence the experience. The sample of eight caregivers, drawn from a geriatric rehabililition hospital, completed a stress scale pre- and postgroup involvement as well as participated in an in-depth interview. Qualitative data was analyzed using a modified grounded theory approach. The results from this study indicate that despite few changes in perception of stress following group involvement, there are benefits to be derived from participation in a caregiver support group. As a group, respondents reported minimal change in their experience of stress both during the interviews as well as on the standardized stress scale. However, respondents did indicate an increased sense of support as well as feeling more confident and prepared for the challenges of caregiving. Similar to previous studies, caregivers who attended the support group program generally reported satisfaction with the group experience. The study highlights the significance of individual differences in caregiving situations and in the experience of caregiver stress. The study also addresses issues of accountability within social work practice and provides direction for future service delivery to family caregivers of elderly persons.

description: We consider dynamical systems for which the spatial extension plays an important role. For these systems, the notions of attractor, epsilon-entropy and topological entropy per unit time and volume have been introduced previously. In this paper we use the notion of Kolmogorov complexity to introduce, for extended dynamical systems, a notion of complexity per unit time and volume which plays the same role as the metric entropy for classical dynamical systems. We introduce this notion as an almost sure limit on orbits of the system. Moreover we prove a kind of variational principle for this complexity.

description: The electric quadrupole coupling constant of the ground state of 37K(3/2+, 1.22 s) in a tetragonal KH2PO4 single crystal was measured to be |eqQ/h| = 2.99 +- 0.07 MHz using the beta-ray detecting nuclear quadrupole resonance technique. The electric quadrupole moment of 37K was determined to be |Q(37K)| = 10.6 +- 0.4 efm2, where the known electric quadrupole coupling constant of stable 39K in the KH2PO4 crystal was used as a reference. The present experimental result is larger than that predicted by shell-model calculations in the sd or the sd and fp model spaces. A possible variation of effective charges was explored to explain the discrepancy.

Οι μοριακοί δείκτες SCoT ταξινόμησαν τις 30 από τις 31 ποικιλίες σε 6 ομάδες εκτός από την F-013/06 ποικιλία. Σύμφωνα με τους μοριακούς δείκτες ISSR οι 29 από τις 31 ποικιλίες ταξινομήθηκαν σε 8 ομάδες εκτός των ποικιλιών SK018/06 και ANP132/07. Οι καταχωρήσεις IS-024/07, IS-095/07 ( καυτερές- διακοσμητικές ) και XKA-115/07 ( καυτερή – νωπή κατανάλωση ) ομαδοποιήθηκαν σε κοινό κλάδο τόσο στην ανάλυση των SCoT δεικτών όσο και των ISSR. Επίσης για πρώτη φορά αλληλουχήθηκε μέρος του γονιδίου fas στην ποικιλία ‘ Raiko ’ το οποίο παρουσίασε 76% ομολογία με την πρωτεΐνη της τομάτας. Η ποσοτικοποίηση της έκφρασης του έδειξε ότι το γονίδιο εκφράζεται περισσότερο στους καρπούς 30 ημερών. Η γενετική ταξινόμηση των παραπάνω ποικιλιών και η κατανόηση των μηχανισμών που συσχετίζονται με το σχηματισμό του καρπού μπορεί να βοηθήσει στη βελτίωση τόσο με συμβατικά όσο και με βιοτεχνολογικά μέσα.
description: Capsicum annum, a worldwide vegetable of American origin, is extremely variable in fruit characteristics. The genetic diversity of thirty one pepper landraces of Greece were investigated using start codon targeted ( SCoT ) polymorphism and inter-simple sequence repeat ( ISSR ) markers. The molecular marker SCoT classified 30 of 31 landraces into 6 group except from F-013/06. According to molecular marker ISSR 29 of 31 landraces classified into 8 group except from SK018/06 and ANP132/07. It is important to note that landraces IS-024/07, IS-095/07 ( chilly, ornamental ) and XKA-115/07 ( chilly, fresh consumption ) are grouped together in two dendrograms produced by SCoT and ISSR primers analysis, forming a distinct clade. It was the first time that gene fas was sequenced in Raiko variety which presents homology 76% to tomato protein. Quantification of gene expression revealed that fas gene expressed more in leaves and 10 days fruit. The genetic diversity of the thirty one landraces and the understanding of mechanism, which are associated with the shape of fruit, can help breeding with both conventional and biotechnological techniques.

The relative K-groups K_q(A[x]/(x^m),(x)) and the Nil-groups Nil_q(A[x]/(x^m)) were evaluated earlier by the author and Madsen in terms of the big de Rham-Witt groups of the ring A. In this paper, we evaluate the maps of relative K-groups and Nil-groups induced by the canonical projection from A[x]/(x^m) to A[x]/(x^n). The result depends strongly on the prime p. It generalizes work of Stienstra on the groups in degrees 2 and 3.

description: We propose and experimentally demonstrate a self-calibrating detector of Cooper pair depairing in a superconductor based on a mesoscopic superconducting island coupled to normal metal leads. On average, exactly one electron passes through the device per broken Cooper pair, independent of the absorber volume, device or material parameters. The device operation is explained by a simple analytical model and verified with numerical simulations in quantitative agreement with experiment. In a proof-of-concept experiment, we use such a detector to measure the high-frequency phonons generated by another, electrically decoupled superconducting island, with a measurable signal resulting from less than 10 fW of dissipated power.

description: Stakeholders' expectations and technology constantly evolve during the lengthy development cycles of a large-scale computer based system. Consequently, the traditional approach of baselining requirements results in an unsatisfactory system because it is ill-equipped to accommodate such change. In contrast, systems constructed on the basis of Capabilities are more change-tolerant; Capabilities are functional abstractions that are neither as amorphous as user needs nor as rigid as system requirements. Alternatively, Capabilities are aggregates that capture desired functionality from the users' needs, and are designed to exhibit desirable software engineering characteristics of high cohesion, low coupling and optimum abstraction levels. To formulate these functional abstractions we develop and investigate two algorithms for Capability identification: Synthesis and Decomposition. The synthesis algorithm aggregates detailed rudimentary elements of the system to form Capabilities. In contrast, the decomposition algorithm determines Capabilities by recursively partitioning the overall mission of the system into more detailed entities. Empirical analysis on a small computer based library system reveals that neither approach is sufficient by itself. However, a composite algorithm based on a complementary approach reconciling the two polar perspectives results in a more feasible set of Capabilities. In particular, the composite algorithm formulates Capabilities using the cohesion and coupling measures as defined by the decomposition algorithm and the abstraction level as determined by the synthesis algorithm.

description: We propose the first general PAC-Bayesian generalization bounds for adversarial robustness, that estimate, at test time, how much a model will be invariant to imperceptible perturbations in the input. Instead of deriving a worst-case analysis of the risk of a hypothesis over all the possible perturbations, we leverage the PAC-Bayesian framework to bound the averaged risk on the perturbations for majority votes (over the whole class of hypotheses). Our theoretically founded analysis has the advantage to provide general bounds (i) that are valid for any kind of attacks (i.e., the adversarial attacks), (ii) that are tight thanks to the PAC-Bayesian framework, (iii) that can be directly minimized during the learning phase to obtain a robust model on different attacks at test time.

description: Functionals in geometric probability are often expressed as sums of bounded functions exhibiting exponential stabilization. Methods based on cumulant techniques and exponential modifications of measures show that such functionals satisfy moderate deviation principles. This leads to moderate deviation principles and laws of the iterated logarithm for random packing models as well as for statistics associated with germ-grain models and $k$ nearest neighbor graphs.

Early postpartum discharge : factors affecting a woman’s decision not to participate
Creators: name: Mahy, Jill
Publisher: name: University of British Columbia
Year: 2009

description: This study was designed to investigate factors influencing a woman’s decision not to participate in an early postpartum discharge program. A factor-searching exploratory survey study was chosen for this study. The conceptual framework directing the study was Pender’s (1987) Health Promotion Model. The sample was composed of 55 postpartum women who gave birth at a tertiary care maternity hospital during a two month period. The study participants and their newborns had met the hospital’s early discharge program criteria but the women had made the decision not to participate. All the women in the study were interviewed by the investigator on their second or third postpartum day prior to hospital discharge. The reasons expressed by the women for not participating in the hospital’s early discharge program were grouped into two major categories: need for physical and emotional restoration, and need for care. External and internal influences on their decision were also identified. The need for physical and emotional restoration included the following: need for sleep, rest and relaxation, need for comfort, and need for time alone. The need for care included: need for help, need for support, and need for protection. External and internal influences and barriers affecting a woman’s decision to stay in the hospital included: children at home, no help at home, lack of awareness of the program and influences of physician and family. Recommendations from this study include the need for further research to examine the perceptions and benefits of early discharge in regards to consumers, varying cultural groups, and health-care professionals. Education with respect to the concept of early discharge is also needed. Postpartum preparation and planning for women and their families in the prenatal period through strong collaboration and networking between hospitals and community health units, and the establishment of family, community support systems, and resources is crucial. Development of a regional wide perinatal home care program, standardized perinatal healthcare and follow-up for childbearing women and their families is also strongly recommended.

description: Entanglement between the spins of top-quark pairs produced at a collider can be used to test a (generalized) Bell inequality at energies never explored so far. We show how the measurement of a single observable can provide a test of the violation of the Bell inequality at the 98% CL with the data already collected at the Large Hadron Collider and at the 99.99% CL with the higher luminosity of the next run.

description: A 3D biomechanical finite element model of the face is presented. Muscles are represented by piece-wise uniaxial tension cable elements linking the insertion points. Such insertion points are specific entities differing from nodes of the finite element mesh, which makes possible to change either the mesh or the muscle implementation totally independently of each other. Lip/teeth and upper lip/lower lip contacts are also modeled. Simulations of smiling and of an Orbicularis Oris activation are presented and interpreted. The importance of a proper account of contacts and of an accurate anatomical description is shown
A comparison of the effects of multicultural and anti-racist teaching on student attitude change
Creators: name: Segawa, Megumi
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study is to examine the effects of Social Studies programs on students' attitudes toward and beliefs about First Nations people in Canada. There were two programs: a multicultural program and an anti-racist program. The multicultural group studied examples of successful First Nations people and the efforts to take responsibilities for their own affairs. The anti-racist group studied the current situation among the majority of First Nations Canadians and then examined historical relationship between the government and First Nations people. Students7 attitudes toward First Nations people were assessed by three measures of empathy (sympathy), attitude, and attribution of blame. Scores on the measure of 'belief in a just world' were used as an independent variable to examine the relationship between the just world belief and the way students in the experimental group responded to the three outcome scales. Two hundred fiftyone grade 11 students from two secondary schools in the Lower Mainland participated in this study. Out of two hundred fifty-one, 169 subjects were eligible for the statistical analysis. Students in the multicultural group significantly increased their scores on the measure of attitude toward First Nations people. Students in the antiracist group significantly improved their scores on the measures of empathy (sympathy) and attribution of blame.

description: We study the transverse quantum ANNNI model in the region of high frustration (k>0.5) using the DMRG algorithm. We obtain a precise determination of the phase diagram, showing clear evidence for the existence of a floating phase, separated from the paramagnetic modulated phase by a high-order critical line ending at the multicritical point. We obtain simple and accurate formulae for the two critical lines.

description: The majority of massive stars live in binary or multiple systems and will interact during their lifetimes, which helps to explain the observed diversity of core-collapse supernovae. Donor stars in binary systems can lose most of their hydrogen-rich envelopes through mass transfer, which not only affects the surface properties, but also the core structure. However, most calculations of the core-collapse properties of massive stars rely on single-star models. We present a systematic study of the difference between the pre-supernova structures of single stars and stars of the same initial mass (11 - 21\Msun) that have been stripped due to stable post-main sequence mass transfer at solar metallicity. We present the pre-supernova core composition with novel diagrams that give an intuitive representation of the isotope distribution. As shown in previous studies, at the edge of the carbon-oxygen core, the binary-stripped star models contain an extended gradient of carbon, oxygen, and neon. This layer originates from the receding of the convective helium core during core helium burning in binary-stripped stars, which does not occur in single-star models. We find that this same evolutionary phase leads to systematic differences in the final density and nuclear energy generation profiles. Binary-stripped star models have systematically higher total masses of carbon at the moment of core collapse compared to single star models, which likely results in systematically different supernova yields. In about half of our models, the silicon-burning and oxygen-rich layers merge after core silicon burning. We discuss the implications of our findings for the explodability, supernova observations, and nucleosynthesis from these stars. Our models will be publicly available and can be readily used as input for supernova simulations. [Abridged]

description: Στην εργασία αυτή επιχειρήθηκε η ανίχνευση της σχέσης μεταξύ του λαϊκού πλούτου και της σύγχρονης έντεχνης λογοτεχνίας. Τα λογοτεχνικά παραδείγματα που χρησιμοποιήθηκαν για αυτόν τον σκοπό ήταν τα έργα της Ζυράννας Ζατέλη, του Σωτήρη Δημητρίου και του Μάρκου Μέσκου. Η λογοτεχνία για ακόμα μια φορά στην ελληνική ιστορία στρέφεται προς το αντικείμενο της λαογραφίας, αυτήν την φορά όμως δεν προσπαθεί να ενώσει ένα έθνος, αλλά να αναδείξει την ομορφιά και την φυσικότητα της ετερότητας. Σύγχρονοι συγγραφείς επεξεργάζονται παραδοσιακούς τρόπους ζωής, θρύλους, παραμύθια, τραγούδια και ντοπιολαλιές, κοιτούν την χαμένη σχέση του ανθρώπου με την γη και αναζητούν τα ερεθίσματα των παππούδων τους. Ο σκοπός τους δεν είναι μονάχα να καταδείξουν τις βίαιες και αστραπιαίες ιστορικές αλλαγές, μα προσπαθούν να ξαναμαγέψουν ένα κόσμο που απέμεινε αμάγευτος και αφιλόξενος. Προσπαθούν να θέσουν στο μέλλον έναν στόχο, δεν μιλάμε για μια ακόμη αναζήτηση του υψηλού, αλλά μέσα στην πολυπλοκότητα της νεωτερικότητας, μέσα σε αυτόν τον επίμονο αγώνα δρόμου για την εξέλιξη, οι συγγραφείς μας στέκονται σκεφτικοί κάνοντας μια επίκληση για τρυφερότητα.
description: In this task we try to find the relationship between folk culture and modern literature. As literary examples we use the works of Zyranna Zateli, Sotiri Dimitriou and Marko Mesko. Literature one more time in Greek history uses the items of folklore, this time the aim is not the unit of a nation but the promotion of beauty and the naturalness of diversity. Modern writers process traditional ways of life, legends, fairy tales, songs and native languages, they observe the lost connection between man and nature and they looking for the stimuli of their grandparents. Their will is not only to show the violent and quick historical changes, but they try to bring back the magic in an inhospitable world. They try to put an aim to the future, not one more pursuit of sublime, but inside the complexity of modernity, inside the subborn way of evolution, our writers make an invocation for tenderness.
