Esclavage, confréries noires, sainteté noire et pureté de sang au Portugal (XVIe-XVIIIe siècles)
Creators: name: Lahon, Didier
Publisher: name: Lusitania Sacra
Year: 2003

description: Cet article aborde quelques problématiques liées à la question de l’esclavage des Noirs Africains au Portugal, au cours de l’Ancien Régime, à Lisbonne en particulier. Un rapide examen du cadre démographique et juridique, qui détermine l’expansion puis le déclin progressif du nombre d’esclaves et des populations qui en sont issues, introduit l’analyse de l’évolution de l’attitude du pouvoir politique et religieux à l’égard des Confréries religieuses catholiques de Noirs. L’auteur montre que ces institutions d’encadrement idéologique et religieux, instruments d’acculturation et de réduction de l’altérité, initialement et théoriquement destinées à favoriser l’intégration à une communauté spirituelle voire sociale, grâce à certains privilèges, finissent par consacrer progressivement les identités sociales en différence de nature essentialistes dont l’application de la clause de pureté de sang aux noirs et mulâtres libres constitue le meilleur exemple d’ordre institutionnel. Est également analysé l’usage politique et religieux du culte des quatre saints noirs du calendrier romain de l’époque.

A Coroa e a Igreja na Lisboa de quinhentos

Publisher: name: Lusitania Sacra

description: No Portugal moderno, as relações entre a Coroa e a Igreja resolveram-se entre momentos de concorrência em que as duas formas de poder competiram pela primazia no palco das tensões políticas, e outros de colaboração em que os dois concertaram esforços para a persecução de objectivos comuns. Tais tensões são particularmente visíveis nos edifícios religiosos a que a Coroa se associou durante os reinados de D. Manuel e D. João III. Este artigo centra-se num conjunto de igrejas encomendadas de raíz (a capela real de São Tomé, em Lisboa, ou a ermida de Nossa Senhora da Conceição, em Tomar), reformadas (o convento de Cristo, em Tomar) ou usadas para uma cerimónia particular (São Domingos ou a Sé, ambas em Lisboa) durante estes reinados, quer na sua distribuição geográfica, quer nas opções estéticas que documentam, procurando nelas identificar sintomas dos projectos políticos a que corresponderam e que materializaram. Ainda duas igrejas (São Sebastião e o mosteiro de São Vicente-de-Fora) mostram como os edifícios religiosos serão ainda, nos dois reinados seguintes, sintomas das transformações por que passam as relações entre os monarcas que as encomendaram e as instituições religiosas a que foram entregues.

description: The most profound effect of disorder on electronic systems is the localization of the electrons transforming an otherwise metallic system into an insulator. If the metal is also a superconductor then, at low temperatures, disorder can induce a dramatic transition from a superconducting into an insulating state. An outstanding question is whether the route to insulating behavior proceeds via the direct localization of Cooper pairs or, alternatively, by a two-step process in which the Cooper pairing is first destroyed followed by the standard localization of single electrons. Here we address this question by studying the local superconducting gap of a highly disordered, amorphous, superconductor by means of scanning tunneling spectroscopy. Our measurements reveal that, in the vicinity of the superconductor-insulator transition, the coherence peaks in the one-particle density of states disappear while the superconducting gap remains intact indicating the presence of localized Cooper pairs. Our results provide the first direct evidence that the transition in our system is driven by Cooper pair localization.

D. Manuel de Almada, bispo de Angra: sua trajectória político-social e religiosa (? - 1580)
Creators: name: Veiga, Carlos Margaça
Publisher: name: Lusitania Sacra
Year: 2003

description: D. Manuel de Almada foi um bispo cuja vida atravessou quase todo o século XVI, época de importantes mutações, algumas das quais se encontram reflectidas na sua trajectória e perfil pessoais. Com a reconstituição do seu itinerário apresenta-se um estudo de caso de um prelado que ascendeu a uma mitra insular – Angra –, em tempos de clima reformador marcado pelo concílio de Trento, embora antes de concluído, o que o torna figura paradigmática de uma época de charneira. Tal percepção levou a indagar sobre antecedentes relevantes como o estatuto social, ficando bem apurado ter nascido no seio de família com tradição de cargos na alta magistratura. A formação universitária em direito canónico e a ordem de presbítero abriram-lhe o caminho do serviço régio e da Igreja. Como cónego da sé de Lisboa e depois chantre servirá na Inquisição, a grande porta de acesso ao episcopado. Sem nunca ter visitado a diocese manter-se-á no exercício de cargos da órbita do poder central e do meio cortesão. Encontrava-se nesta dualidade de funções quando se abriu a grande crise de sucessão dinástica com a morte de D. Sebastião. Ao tornar-se seguidor de D. António, prior do Crato, desafiou o poder de Filipe II. Nesta luta procurou a morte aquele que até ao fim da vida teve o título de bispo de Angra embora há muito resignatário.

description: The spectra emitted from clouds near the Galactic Centre are investigated calculating the UV-optical-IR lines using the physical parameters and the element abundances constrained by the fit of mid-IR observations. The characteristic line ratios are compared with those observed in active galaxies. We have found that the physical conditions in the nebulae near the GC are different from those of starburst galaxies and AGN, namely, gas velocities and densities as well as the photoionization fluxes are relatively low. The geometrical thickness of the emitting nebulae is particularly small suggesting that matter is strongly fragmented by instabilities leading to an underlying shock-generated turbulence.

Os bispos e a Inquisição Portuguesa (1536-1613)
Creators: name: Silva, José Pedro
Publisher: name: Lusitania Sacra
Year: 2003

description: O objectivo principal deste artigo é o de analisar as relações entre o poder episcopal e o Tribunal do Santo Ofício, durante o período de estabelecimento, organização e consolidação da Inquisição, ou seja, a época que decorre entre a criação definitiva desta, em 1536, e a promulgação do seu primeiro Regimento impresso, em 1613. A tese central que se procura sustentar é a de que as relações entre estes dois pólos de poder do campo religioso foram por norma de grande cordialidade, cooperação e até complementaridade, pese embora a afloração de algumas dissenções pontuais, fricções que foram um pouco mais vivas após o Concílio de Trento. Significa isto que o caso português, tal quanto os estudos disponíveis possibilitam vislumbrar, teria sido distinto da situação verificada nos territórios onde também actuaram Inquisições modernas, a saber Espanha e Itália.

Algonquin Ekwânamo matrix project : "a place to interface", for elders, indigenous scientists/non-indigenous scientists, indigenous knowledge systems and western science systems
Creators: name: Robinson, Jocelyne Virginia
Publisher: name: University of British Columbia
Year: 2015

description: This research is consistent with literature that states there are inequities relating to the under-representation of Indigenous students in the subjects of math, science and technology in education as compared to Non-Indigenous people in Canada. The analysis of nine in-depth interviews and the process of documentary explores two questions that this thesis aims to address: From the perspectives and dialogues of three Elders, three Indigenous scientists, and three Non-Indigenous scientists who have contemplated the ways to address the tensions between Indigenous Knowledge Systems and Western Science Systems: What are the educational possibilities, challenges, and benefits of having these systems interface? How can art, technology and dialogue be mediums for exploring the interface between these systems so that Indigenous learners may be motivated to participate in both knowledge systems? An interplay between three theoretical, methodological frameworks of Indigenous Storywork (Archibald, 2008a, 2008b), Irwin in A/r/tography (Irwin & Springgay, 2008), Implicate Order (Bohm, 2007) and through the development of a fourth theoretical, methodological framework the Algonquin Ekwânamo Matrix Project shape this research. Four themes emerged from this analysis: [1] Language and Story as Tools for Critical Thinking [2] Culture and Ecological Mindfulness in Kinships with Nature and All Living Entities [3] Identity and Relevance in Education as Seeing Ourselves in Academia [4] Presence and Wholistic Learning From the Heart. Four A’s Strategies emerged from the in-depth interviews in relation to the four themes that may incite new ways for building complementary relationships in science education: The first is Activating Indigenous and Non-Indigenous Knowledge Encounters Through Dialogue; second is Aligning Indigenous Knowledge Interfaces Through Dialogical Strategies; third is Applying Indigenous Knowledge and Western Science Interfacing Through Co-created Strategies in Bohmian Dialogue and First Nations Circles; and fourth is Anticipating Innovative Knowledge Enhancements through decentralized think tank groups that align with Indigenous culturally competent ways for accessing well being. This research study helped develop the Algonquin Ekwânamo Matrix Project’s theoretical and methodological framework that foreground the need to address the global ecological crisis through meaningful dialogue, respectful relationships and a new science paradigm that reflects wholistically art, science, diverse philosophies and perspectives.

description: The recent construction and analysis of deformations of quantum field theories by warped convolutions is extended to a class of curved spacetimes. These spacetimes carry a family of wedge-like regions which share the essential causal properties of the Poincare transforms of the Rindler wedge in Minkowski space. In the setting of deformed quantum field theories, they play the role of typical localization regions of quantum fields and observables. As a concrete example of such a procedure, the deformation of the free Dirac field is studied.

Stimulus Pastorum: texto e contexto de uma proposta de renovação
Creators: name: Barbosa, David Sampaio
Publisher: name: Lusitania Sacra
Year: 2003

description: A obra Stimulus Pastorum é uma das muitas obras que nos deixou Frei Bartolomeu dos Mártires. O texto tem muito a ver com o percurso humano, intelectual e espiritual que caracterizaram o arcebispo bracarense. Trata-se iminentemente dum escrito de natureza espiritual, onde referências e paradigmas reflectem a articulação exemplar prosseguida pelo arcebispo duma proximidade a Deus e aos muitos fiéis que pastoralmente dele dependiam. A experiência bracarense e a estada em Trento (1561-1563) levaram-no a acreditar ser possível uma reforma abrangente para toda a Igreja. A Stimulus Pastorum significou um gesto inovador e propósito ousado para o tempo. Está-se perante uma convicção, assumida por um arcebispo que, ao assumir mudança para si (reforma), profeticamente prenuncia a possibilidade de revigoramento espiritual do cristianismo naquela segunda metade do século XVI. Texto e contexto determinaram o percurso duma reforma possível que, a todos os títulos, não desmereceu doutros pastores (Carlos Borromeu emMilão e Paleotti em Bolonha) que pelo mundo católico de então implementavam práticas e intuições oportunamente relevadas e aprovadas em Trento.

description: A common explanation for the origins and rising prevalence of asthma is that they involve complex interactions between hereditary predispositions and environmental exposures that are incompletely understood. Yet, emerging evidence substantiates the paradigm that environmental exposures prenatally and during very early childhood induce epigenetic alterations that affect the expression of asthma genes and, thereby, asthma itself. Here, we review much of the key evidence supporting this paradigm. First, we describe evidence that the prenatal and early postnatal periods are key time windows of
susceptibility to environmental exposures that may trigger asthma. Second, we explain how environmental epigenetic regulation may explain the immunopathology underlying asthma. Third, we outline specific evidence that environmental exposures induce epigenetic regulation, both from animal models and robust human epidemiological research. Finally, we review some emerging topics, including the importance of coexposures, population divergence, and how epigenetic regulation may change over time. Despite all the inherent complexity, great progress has been made toward understanding what we still consider reversible asthma risk factors. These, in time, may impact patient care.
Identification of novel androgen receptor inhibitors for the treatment of castration resistant prostate cancer
Creators: name: Munuganti, Ravi Shashi Nayana
Publisher: name: University of British Columbia
Year: 2015

description: Interest in developing androgen receptor (AR) inhibitors with novel mechanism of action for the treatment of prostate cancer (PCa) is on the rise since the commercial anti-androgens (including recently approved drug, Enzalutamide) face clinical limitations. Current therapies fail over a period of time because they all target mutation-prone androgen binding pocket on AR to which the receptor has already developed effective resistance mechanisms. Hence, there is a pressing need for novel therapeutics that inhibit the AR through alternative modes of action. To address this problem, we have used in silico drug design methodology to create new drugs that act on an entirely different site on the AR, a recently identified co-activator site called binding function-3 (BF3). This dissertation describes the discovery and development of novel anti-androgens directed towards the BF3 surface of the AR. These inhibitors were developed through a series of computational experiments followed by extensive biological validations. Based on the activity profile of the identified inhibitors, it can be anticipated that these drug prototypes will lay a foundation for the development of alternative or supplementary small-molecule therapies capable of combating PCa even in its drug resistant forms. Because the emergence of castration resistance is the lethal end stage of the disease, we anticipate that the thesis work will eventually have a substantial impact on the survival of prostate cancer patients.

Language as a special signal : infants' neurological and social perception of native language, non-native language, and language-like stimuli
Creators: name: May, Lillian Anne
Publisher: name: University of British Columbia
Year: 2015

description: The capacity to acquire language is believed to be deeply embedded in our biology. As such, it has been proposed that humans have evolved to respond specially to language from the first days and months of life. The present thesis explores this hypothesis, examining the early neural and social processing of speech in young infants. In Experiments 1-4, Near-Infrared Spectroscopy is used to measure neural activation in classic “language areas” of the cortex to the native language, to a rhythmically distinct unfamiliar language, and to a non-speech whistled surrogate language in newborn infants (Experiments 1 & 2) as well as infants at 4 months of age (Experiments 3 & 4) in. Results revealed that at birth, the brain responds specially to speech: bilateral anterior areas are activated to both familiar and unfamiliar spoken language, but not to the whistled surrogate form. Different patterns were observed in 4 month-old infants, demonstrating how language experience influences the brain response to speech and non-speech signals. Experiments 5-7 then turn to infants’ perception of language as a marker of social group, asking whether infants at 6 and 11 month-olds associate the speakers of familiar and unfamiliar language with individuals of different ethnicities. Infants at 11 months—but not at 6 months—are found to look more to Asian versus Caucasian faces when paired with Cantonese versus English language (Experiments 5, 7). However, infants at the same age did not show any difference in looking to Asian versus Caucasian faces when paired with English versus Spanish (Experiment 6). Together, these results suggest that the 11 month-old infants tested have learned a specific association between Asian individuals and Cantonese language. The experiments presented in this thesis thus demonstrate that from early in development, infants are tuned to language. Such sensitivity is argued to be of critical importance, as it may serve to direct young learners to potential communicative partners.

description: The morphological changes of Si nanowires (Si NWs) cycled in 1:1 ethylene–carbonate (EC)/diethyl–carbonate (DEC) with or without different additives, fluoroethylene carbonate (FEC) or vinylene carbonate (VC), as well as the composition of the deposited solid–electrolyte interphase layer, are investigated by a combination of experimental microscopic and spectroscopic techniques. Scanning electron microscopy and optical spectroscopy highlight that the NW morphology is better preserved in samples cycled in the presence of FEC and VC additives compared to the additive-free electrolyte. However, only the use of FEC is capable of slightly mitigating the amorphization of silicon upon cycling. The solid electrolyte interphase (SEI) formed over the Si NWs cycled in the additive-free electrolyte is richer in organic and inorganic carbonates compared to the SEI grown in the presence of the VC and FEC additives. Furthermore, both additives are able to remarkably limit the degradation of the LiPF6 salt. Overall, the use of the FEC-additive in the carbonate-based electrolyte promotes both morphological and structural resilience of the Si NWs upon cycling thanks to the optimal composition of the SEI layer.

description: Although photometric and spectroscopic surveys with the Spitzer Space Telescope increased remarkably the number of well studied debris disks around A-type and Sun-like stars, detailed analyzes of debris disks around F-type stars remained less frequent. Using the MIPS camera and the IRS spectrograph we searched for debris dust around 82 F-type stars with Spitzer. We found 27 stars that harbor debris disks, nine of which are new discoveries. The dust distribution around two of our stars, HD 50571 and HD 170773, was found to be marginally extended on the 70um MIPS images. Combining the MIPS and IRS measurements with additional infrared and submillimeter data, we achieved excellent spectral coverage for most of our debris systems. We have modeled the excess emission of 22 debris disks using a single temperature dust ring model and of 5 debris systems with two-temperature models. The latter systems may contain two dust rings around the star. In accordance with the expected trends, the fractional luminosity of the disks declines with time, exhibiting a decay rate consistent with the range of model predictions. We found the distribution of radial dust distances as a function of age to be consistent with the predictions of both the self stirred and the planetary stirred disk evolution models. A more comprehensive investigation of the evolution of debris disks around F-type stars, partly based on the presented data set, will be the subject of an upcoming paper.

Forest fragmentation changes macroinvertebrate community composition in neotropical treeholes
Creators: name: Nicolas Stella, Angie Jhovanska
Publisher: name: University of British Columbia
Year: 2015

description: Habitat loss and fragmentation are the main drivers of biodiversity loss in terrestrial ecosystems, particularly in the tropics. Fragmented habitats can interfere with organism dispersion, population persistence and ecosystem functions but empirical studies report variation in the sensitivity of species and processes to fragmentation and the mechanisms operating behind observed responses remain poorly understood. In this study we examined the effects of forest fragmentation on the colonization of artificial treeholes in northwestern Costa Rica by measuring the responses at the community level. We explored four potential mechanisms driving differences in macroinvertebrate communities between continuous and fragmented forests: dispersal limitation, microclimate changes and bottom up or top down effects. Macroinvertebrate community composition differed significantly between continuous forests and forest remnants but not in the predicted direction. Our results suggest that treeholes in fragmented forest contain higher abundance of detritivores and experience changes in predator species identity consistent with increased nutrient input and a potential relaxation of predation pressure in small forest remnants. An overall resilience of treehole communities to forest fragmentation is interpreted with care as time-delayed responses to fragmentation continue to be a possibility. These findings advance our understanding of the response of biological communities to forest fragmentation and emphasize the value of preserving even small forest remnants for biodiversity conservation.

description: Personal air pollution monitoring in research studies should not interfere with usual patterns of behavior and bias results. In an urban pediatric cohort study we tested whether wearing an air monitor impacted activity time based on continuous watch-based accelerometry. The majority (71%) reported that activity while wearing the monitor mimicked normal activity. Correspondingly, variation in activity while wearing versus not wearing the monitor did not differ greatly from baseline variation in activity (P = 0.84).

The Larmor frequency of optically-injected spins is modulated when the spins are dragged through a region of spin-polarized nuclei created at a MnAs/GaAs interface. The effective field created by the nuclei is controlled either optically or electrically using the ferromagnetic proximity polarization effect. Spin rotation is also tuned by controlling the carrier traverse time through the polarized region. We demonstrate coherent spin rotations exceeding 4 pi radians during transport.

We present results for the gs energy, magnetic order parameter, spin-spin correlation function, and plaquette valence-bond crystal (PVBC) susceptibility. We find a Néel antiferromagnetic (AFM) phase for $κ< κ_{c_{1}} \approx 0.47$, a collinear striped AFM phase for $κ> κ_{c_{2}} \approx 0.60$, and a paramagnetic PVBC phase for $κ_{c_{1}} \lesssim κ\lesssim κ_{c_{2}}$. The transition at $κ_{c_{2}}$ appears to be of first-order type, while that at $κ_{c_{1}}$ is continuous. Since the Néel and PVBC phases break different symmetries our results favor the deconfinement scenario for the transition at $κ_{c_{1}}$.

description: Background: Social and environmental stressors, may modify associations between environmental pollutants and asthma symptoms. We examined if neighborhood asthma prevalence (higher: HAPN vs. lower: LAPN), a surrogate for underlying risk factors for asthma, modified the relationship between pollutants and urgent asthma visits. Methods: Through zip code, home addresses were linked to New York City Community Air Survey’s land use regression model for street-level, annual average nitrogen dioxide (NO2), particulate matter (PM2.5), elemental carbon (EC); summer average ozone (O3); winter average sulfur dioxide (SO2) concentrations. Poisson regression models were fit to estimate the association (prevalence ratio, PR) between pollutant exposures and seeking urgent asthma care. Results: All pollutants, except O3 were higher in HAPN than LAPN (P<0.01) Neighborhood asthma prevalence modified the relationship between pollutants and urgent asthma (P-interaction<0.01, for NO2 and SO3). Associations between pollutants and urgent asthma were observed only in LAPN (NO2: PR=1.38, P=0.01; SO3: PR=1.85, P=0.04). No association was observed between pollutants and urgent asthma among children in HAPN (P>0.05). Conclusions: Relationships between modeled street-level pollutants and urgent asthma were stronger in LAPN compared to HAPN. Social stressors that may be more prevalent in HAPN than LAPN, could play a greater role in asthma exacerbations in HAPN versus pollutant exposure alone.

description: We present the improved solar radio spectrograph of the University of Athens operating at the Thermopylae Satellite Telecommunication Station. Observations now cover the frequency range from 20 to 650 MHz. The spectrograph has a 7-meter moving parabola fed by a log-periodic antenna for 100 650 MHz and a stationary inverted V fat dipole antenna for the 20 100 MHz range. Two receivers are operating in parallel, one swept frequency for the whole range (10 spectrums/sec, 630 channels/spectrum) and one acousto-optical receiver for the range 270 to 450 MHz (100 spectrums/sec, 128 channels/spectrum). The data acquisition system consists of two PCs (equipped with 12 bit, 225 ksamples/sec ADC, one for each receiver). Sensitivity is about 3 SFU and 30 SFU in the 20 100 MHz and 100 650 MHz range respectively. The daily operation is fully automated: receiving universal time from a GPS, pointing the antenna to the sun, system calibration, starting and stopping the observations at preset times, data acquisition, and archiving on DVD. We can also control the whole system through modem or Internet. The instrument can be used either by itself or in conjunction with other instruments to study the onset and evolution of solar radio bursts and associated interplanetary phenomena.

Democracy and silence : rethinking the meanings and significance of silent citizenship in democratic systems
Creators: name: Gray, Sean William David
Publisher: name: University of British Columbia
Year: 2020

description: Contemporary democratic theory is focused on empowering voice in collective political decision-making. The opposite of voice is silence: Citizens may remain silent rather than vocalize their preferences, needs, interests, or ideals. Yet traditional understandings of voice and silence in democratic theory fail to capture the changing circumstances of politics in developed liberal democracies, including shifting patterns of participation and nonparticipation, rising levels of distrust and disaffection, and an increasing tendency among citizens to choose silence over voice. But because contemporary democratic theory equates silence with deficits of democracy the meanings and significance of silence have not been adequately conceptualized. How, then, should we theorize and assess the silence of citizens in a democracy? Can silence itself ever be a form of political engagement? In this dissertation, I offer tools for conceptualizing the dangers and possibilities for democracy that silent citizenship might pose, both as a symptom of political disempowerment and as an expression of political engagement. To do so, I develop a theoretical framework that maps different choices for silence to their expected political consequences. I identify four types of communicative silence that citizens may use to engage politically: affective, demonstrative, emulative, and facilitative communicative silence. I argue that, under certain circumstances, each of these four types of communicative silence can function as a low-cost, low-risk method for citizens to influence collective political decision-making, especially where opportunities for voice-based influence are limited. I suggest that greater attention to the expressive dimension of silent citizenship should motivate democratic theorists to design democratic institutions and practices to better anticipate and support communicative uses of silence in politics. To illustrate how the expressive possibilities of silent citizenship might be empowered, I propose a series of mechanisms that could enable and protect communicative choices for silence in electoral systems, representative relationships, and democratic deliberation. Understanding the democratic potentials of silence, I conclude, can provide a framework for evaluating otherwise neglected forms of political engagement, enhancing our capacity to imagine alternative means and methods of democratic influence, to improve collective decision-making, and to strengthen bonds of authorization and accountability between citizens and democratic institutions.

description: We present a summary of gamma-ray millisecond pulsar (MSP) observations with the Fermi Large Area Telescope. The radio and gamma-ray light curves of these MSPs have been modeled in the framework of the retarded vacuum dipole magnetic field. Likelihood fitting of the radio and gamma-ray light curves with geometric emission models allows us to give model-dependent confidence contours for the viewing geometry in these systems which are complementary to those from polarization measurements.

Τρίτη ηλικία
Ψυχική υγεία
Κοινωνικός αποκλεισμός

description: Η γήρανση είναι μια βιολογική διαδικασία που συμβαίνει συνεχώς σε όλη τη διάρκεια της ζωής και ο άνθρωπος είναι αδύναμος να τη σταματήσει. Καθώς γερνούν, τα ηλικιωμένα άτομα βιώνουν διάφορες βιολογικές, ψυχολογικές και κοινωνικές αλλαγές. Από το 2020, όταν η πανδημία του ιού Covid-19 εξαπλώθηκε σε όλο τον κόσμο αλλά και στην Ελλάδα, τέθηκαν περιορισμοί, με πρωταρχικό μέτρο την καραντίνα, για να σταματήσει η εξάπλωση του ιού και η επιρροή του στην καθημερινή ζωή των ανθρώπων. Το βάρος της αντιμετώπισης της τρίτης ηλικίας με όποια μορφή προκύπτει, μαζί με τις δυσκολίες που δημιουργούνται από τους περιορισμούς της καραντίνας, είναι αυτό που κάνει την τρίτη ηλικία μοναδική. Σκοπός της παρούσας μελέτης είναι η διερεύνηση των συνεπειών του κοινωνικού αποκλεισμού και της πίεσης στην ψυχική υγεία των ηλικιωμένων κατά τη διάρκεια της πανδημίας Covid-19.Για την εκπόνηση της συγκεκριμένης μελέτης έγινε η χρήση μίας δομημένης συνέντευξης, σε ένα πλήθος 15 ατόμων τρίτης ηλικίας, μέλη σε ΚΑΠΗ και μέλη του Θρακομικρασιατικού Συλλόγου, στο Νομό Δράμας στο Δ.

description: Environmental toxicants can exert adverse health effects via epigenetic regulation. We conducted a review of studies assessing traffic-related air pollution (TRAP) exposure and breast cancer (BC) risk, and the evidence for epigenetic mediation. 14 epidemiological studies demonstrated associations between TRAP exposure and BC risk, in which a total of 26 comparisons were assessed. 11 of these comparisons reported a positive association; whereas 15 comparisons were negative. Five publications linked TRAP exposure to epigenetic alterations in genes that may be related to BC risk. One animal study provided evidence of TRAP-treatment inducing breast tumorigenesis. Associations between TRAP components polycyclic aromatic hydrocarbons (PAH) and nitrogen dioxide (NO2) and BC risk were more consistent. While evidence for epigenetic regulation remains limited, polycyclic aromatic hydrocarbons (PAH) and nitrogen dioxide (NO2) exposures may alter methylation of breast tumorigenic genes (e.g., EPHB2, LONP1). Future epigenomic studies with environmental measures are needed to interrogate the relationship between TRAP and BC risk.

A sharp correlation inequality with an application to almost sure local limit theorem

description: We prove a new sharp correlation inequality for sums of i.i.d. square integrable lattice distributed random variables. We also apply it to establish an almost sure local limit theorem for iid square integrable random variables taking values in an arbitrary lattice. This extends a recent similar result jointly obtained with Antonini-Giuliano, under a slightly stronger absolute moment assumption (of order $2+u$ with $u>0$). The approach used to treat the case $u>0$ breaks down when $u=0$. MacDonald's concept of the Bernoulli part of a random variable is used in a crucial way to remedy this.
"Plain work to do" : Elizabeth Gaskell's intervening re-productions of seamstress labour
Creators: name: Becker, Alayna Marian
Publisher: name: University of British Columbia
Year: 2015

description: This thesis explores Elizabeth Gaskell’s engagement with and intervention in issues surrounding seamstress labourers, particularly as manifest in her three texts with eponymous seamstresses: “Libbie Marsh’s Three Eras” (1847), Mary Barton (1848), and Ruth (1853). Many scholars have emphasized that representations of seamstresses, including symbolic, proliferated in Victorian culture during the rise of industrialization. Most notably, Lynn M. Alexander argues that authors adopted the seamstress as a metonym for the working class and later as a stand-in for other groups. My study juxtaposes Gaskell’s seamstress fictions with Victorian nonfictional, poetic, and visual representations that helped establish the figure of the Victorian seamstress. However, my readings of Gaskell’s needlewomen are in tension with both recent critical understandings of the seamstress figure in Victorian literature as symbolic or metonymic and popular Victorian constructions of the seamstress; such interpretations do not do justice to the complexity of Gaskell’s seamstress fictions and ultimately dissociate Gaskell’s seamstresses from her depictions of labour conditions as they distinctly affect individual needlewomen. Libbie is a labouring slopworker whose individual physical toil and financial limitations reveal the complex fabric of a gradated working class; Mary is one of three distinct seamstress labourers (along with Margaret and Sally) that lay bare the contradictions inherent in collapsing the nuance of seamstress experience into a single representative figure, while Ruth is a fallen woman whose consistent attempts to find paid labour recognize women’s labour as an economic necessity rather than as simply moral or domestic work. Combined, these chapters reveal that Gaskell challenges the dominant representations of seamstresses; she re-places her seamstresses in the conditions of their labour, mounting an implied critique of a gendered social system that limits the productive capacity of women’s labour.
Giant strain-sensitivity of acoustic energy dissipation in solids containing dry and saturated cracks with wavy interfaces

description: Mechanisms of acoustic energy dissipation in heterogeneous solids attract much attention in view of their importance for material characterization, nondestructive testing, and geophysics. Due to the progress in measurement techniques in recent years it has been revealed that rocks can demonstrate extremely high strain sensitivity of seismo-acoustic loss. In particular, it has been found that strains of order $10^{-8}$ produced by lunar and solar tides are capable to cause variations in the seismoacoustic decrement on the order of several percents. Some laboratory data (although obtained for higher frequencies) also indicate the presence of very high dissipative nonlinearity. Conventionally discussed dissipation mechanisms (thermoelastic loss in dry solids, Biot and squirt-type loss in fluid-saturated ones) do not suffice to interpret such data. Here, the dissipation at individual cracks is revised taking into account the influence of wavy asperities of their surfaces quite typical of real cracks, which can drastically change the values of the relaxation frequencies and can result in giant strain sensitivity of the dissipation without the necessity to assume the presence of unrealistically thin (and, therefore, unrealistically soft) cracks. In particular, these mechanisms suggest interpretation for observations of pronounced amplitude modulation of seismo-acoustic waves by tidal strains.
title: The role of preferences in the context of believing and discerning communities : A Maturanian reading

description: We find ourselves, as interpreters and listeners, living, discerning, prioritizing, asking, and answering questions in and through particular communal and theological traditions. As the discerning and prioritizing process is inevitable, we suggest to move the question about prioritizing from the context of ‘privileged access or interpretation’ to the context of the ‘preferences’ of the believing communities. We imply by this ‘relocation’ the interdependent relationships between believing communities and their beliefs and practices. We propose, following Maturana’s epistemology, three steps to argue about the dynamic and interdependent relationships among believers, communities, and their beliefs and practices. We affirm, first, that whenever we engage in the discerning process we have before us two paths of explanations. These two paths place the believers in a central place in their task for deciding for one of the options. The recognition about the interpreters’ active participation suggests the crucial role of the believers and their preferences. The crucial point in the process of discerning and deciding for one of the paths is the type of believing communities that we would like to promote and conserve. We suggest, second, that the proposal of answers and the acceptation of those answers as explanations imply the active participation of both interpreters and listeners. We propose the interdependence relationships between our existence in particular believing communities and those questions and answers that we prioritize, ignore, and conserve. We claim, third, that in language or in and through our dialogical spaces we distinguish and coordinate the many and possible dimensions of our existence and relationships. As believers, in and through the contexts of our believing communities we discern, prioritize, and conserve the accents of our beliefs and practices. We stress the crucial role of the preferences as the believing communities prioritize and conserve the ‘nature’ and ‘course’ of their particular communities.
