UNRAVELING THE ROLE OF THE HUMAN ENDOGENOUS RETROVIRUSES IN THE PATHOGENESIS OF COLON CANCER
Creators: name: DOLCI, MARIA
Publisher: name: Universit� degli Studi di Milano
Year: 2020

description: Background: Human endogenous retroviruses (HERV) are remnants of exogenous retroviral infections, representing 8% of the human genome. Their regulation is based on the DNA methylation of promoters, the long terminal repeats (LTRs). Transcripts from HERV have been associated with cancers, but reports concerning HERV expression in colorectal cancer remain sporadic. Methods: 63 Italian patients and 58 Tunisian patients with advanced stages of colorectal cancer were enrolled in this study. HERV-H, -K, -R, -P LTRs, and Alu, LINE-1 methylation levels, and the expressions of HERV env and pol gene were investigated by pyrosequencing and by RT qPCR, respectively, in the tumor, normal adjacent tissues, and, when possible, in the blood and plasmatic extracellular vesicles (EVs). Associations among clinical characteristics and HERV expression and methylation levels were also evaluated. The expression of the HERV-K Pol/Env proteins was also evaluated by Western Blot. Results: As for the Italians patients, Alu, LINE-1, HERV-H and -K LTRs were demethylated in the tumor tissues compared to the normal adjacent tissues (p<0.05), while no differences were observed in HERV env gene expression levels, among the clinical specimens. The env gene was expressed in the EVs (p<0.01) of 54% (-H), 38% (-K), 31% (-R) patients. Associations were found between HERV expression and right tumor colon location and between HERV methylation and vascular invasion (p<0.05). HERV K Pol protein was more expressed (p<0.01) in the adjacent normal tissues compared to the tumor tissues. The Env protein was only expressed in the tumor tissue. As for the Tunisian population, LINE-1 was less methylated in the tumor tissue compared to the adjacent normal tissue (p<0.05), while Alu, HERV-K and -H LTRs showed the same trends, but the difference was not significant. The expression of the HERV env and pol genes were similar in the biological samples. No association was found between the HERV expression/methylation and the clinical characteristics of the Tunisian patients. Conclusions: The changes in DNA methylation of retroelements are specific in colorectal cancer but do not correlate with viral overexpression. The Pol protein expression in the normal cells may induce the retrotrascription and the subsequent transfer of HERV sequences into other cells, possibly through EVs. HERV genome insertion might cause cells transformation. In the cancer cells, the Env protein may contribute to the cancer progression through cell to cell fusion.

description: We consider the nonlocal KPP-Fisher equation $u_t(t,x) = u_{xx}(t,x) + u(t,x)(1-(K *u)(t,x))$ which describes the evolution of population density $u(t,x)$ with respect to time $t$ and location $x$. The non-locality is expressed in terms of the convolution of $u(t, \cdot)$ with kernel $K(\cdot) \geq 0,$ $\int_{\mathbb{R}} K(s)ds =1$. The restrictions $K(s), s \geq 0,$ and $K(s), s \leq 0,$ are responsible for interactions of an individual with his left and right neighbors, respectively. We show that these two parts of $K$ play quite different roles as for the existence and uniqueness of traveling fronts to the KPP-Fisher equation. In particular, if the left interaction is dominant, the uniqueness of fronts can be proved, while the dominance of the right interaction can induce the co-existence of monotone and oscillating fronts. We also present a short proof of the existence of traveling waves without assuming various technical restrictions usually imposed on $K$.

title: The effect of acute amoxicillin exposure on anaerobic microbial communities - activity, ecology and resistome
Creators: name: Bruns-Moore, Melissa
Publisher: name: University of Glasgow
Year: 2022

description: Antimicrobial resistant (AMR) genes in water treatment technologies are an issue of global concern. However, the impact of antibiotics on the anaerobic microbial communities within the decentralised wastewater treatment systems such as septic tanks is not well researched. This thesis aims to quantify the effects of an acute shock exposure of amoxicillin on the methanogenic activity, treatment efficacy, and structure of the microbial community in anaerobic granules. The work was conducted using an adapted specific methanogenic assay (SMA) to measure the rate of methane production with additional analytical methods including soluble chemical oxygen demand (sCOD) quantification, next generation sequencing (NGS), and AMR detection using Smart-Chip Real time PCR (quantitative PCR, qPCR) array. This work found that the presence of amoxicillin within the anaerobic microbial communities had measurable effects on the rate of methane production, community assembly, and the concentration of AMR genes within the effluent. However, the influence of amoxicillin on sCOD removal was limited. An additional study was conducted to determine the abiotic decay of amoxicillin within anaerobic culture medium. This study found that the oxygen scavenger L-cysteine has a strong catalytic effect on the decay of amoxicillin. As such, studies assessing the sensitivity of amoxicillin in lab grown cultures should take into account the abiotic decay within the medium used. Overall, the research demonstrates that the impact of pharmaceuticals, such as amoxicillin within decentralised waste treatment systems like septic tanks should be more widely investigated. Although septic tanks are rarely monitored, this work demonstrates that they have the potential to be point sources for the spread of AMR. Furthermore, changes to the microbial community caused by shock exposure to amoxicillin and other pharmaceuticals could lead to septic tank failure and discharge of untreated sewage into the water environment.

description: Temperature compensation is a notable property of circadian oscillators that indicates the insensitivity of the oscillator system's period to temperature changes; the underlying mechanism, however, is still unclear. We investigated the influence of protein dimerization and cooperative stability in protein degradation on the temperature compensation ability of two oscillators. Here, cooperative stability means that high-order oligomers are more stable than their monomeric counterparts. The period of an oscillator is affected by the parameters of the dynamic system, which in turn are influenced by temperature. We adopted the Repressilator and the Atkinson oscillator to analyze the temperature sensitivity of their periods. Phase sensitivity analysis was employed to evaluate the period variations of different models induced by perturbations to the parameters. Furthermore, we used experimental data provided by other studies to determine the reasonable range of parameter temperature sensitivity. We then applied the linear programming method to the oscillatory systems to analyze the effects of protein dimerization and cooperative stability on the temperature sensitivity of their periods, which reflects the ability of temperature compensation in circadian rhythms. Our study explains the temperature compensation mechanism for circadian clocks. Compared with the no-dimer mathematical model and linear model for protein degradation, our theoretical results show that the nonlinear protein degradation caused by cooperative stability is more beneficial for realizing temperature compensation of the circadian clock.

ESPRESSIONE DEI RECETTORI TOLL-LIKE IN ORGANI MURINI ADULTI ED EMBRIONALI
Creators: name: MENON, ALESSANDRA
Publisher: name: Universit� degli Studi di Milano
Year: 2012

description: Toll-like receptors (TLRs) are members of a conserved family of type I transmembrane proteins that play a key role in innate immunity through their function as Pattern Recognition Receptors (PRRs) that detect microbial and non-microbial components known as Microorganism Associated Molecular Patterns (MAMPs).In mammals, TLRs are widely expressed in many cell types, including nervous cells and epithelial and endothelial cells of hollow and parenchymatous organs. Having demonstrated in a previous study the expression of TLR4 and TLR7 in the enteric nervous system (ENS) and dorsal root ganglia (DRGs) of human and murine adults, the aim of the present study was to investigate if their expression is already present during murine peripheral nervous system and other parenchymatous organs (adrenal gland, liver and pancreas) development and to compare with adult pattern of expression.

description: The world communicates to our senses of vision, hearing and touch in the language of waves, as the light, sound, and even heat essentially consist of microscopic vibrations of different media. The wave nature of light and sound has been extensively investigated over the past century and is now widely used in modern technology. But the wave nature of heat has been the subject of mostly theoretical studies, as its experimental demonstration, let alone practical use, remains challenging due to the extremely short wavelengths of these waves. Here we show a possibility to use the wave nature of heat for thermal conductivity tuning via spatial short-range order in phononic crystal nanostructures. Our experimental and theoretical results suggest that interference of thermal phonons occurs in strictly periodic nanostructures and slows the propagation of heat. This finding broadens the methodology of heat transfer engineering by expanding its territory to the wave nature of heat.
CLIMATE CHANGE ALTERS INTERREGIONAL ELECTRICITY DYNAMICS ON THE U.S. WEST COAST
Creators: name: Hill, Joy
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Power systems and markets are influenced by hydrometeorological variability, including temperature-driven changes in electricity demand and water availability impacts to hydropower. The U.S. Pacific Northwest (PNW) meets over 55% of its regional electricity demand with hydropower, a majority of which is produced within the Federal Columbia River Power System. California relies on hydropower produced in-state and imported electricity the PNW to meet demand, leaving California vulnerable to West Coast wide hydrologic variability. As hydroclimate changes across this region, a combination of forces may work in tandem to make West Coast power markets even more susceptible to reliability and price risk. A warmer climate is expected to shift the timing of streamflow earlier in the year and increase summer cooling demand. In this work, we investigate how climate change could alter interregional electricity market dynamics on the West Coast, including the possibility that hydroclimate changes in one region (e.g. PNW) could compound price and reliability risks in another (e.g. California) and vice versa. Power system metrics (generation, demand, market prices) are analyzed for multiple combinations of downscaled Global Climate Models (GCMs), Representative Concentration Pathways (RCPs), hydrologic models and timescales. We find that under static grid conditions, climate change across the West Coast could cause higher average annual wholesale prices and reduced reliability. We find that        hydroclimatic risks for the PNW power system are largely driven by changes in streamflow, while risks for the California system are driven by changes in summer air temperatures, particularly extreme heat waves increasing peak system demand. In addition, we find that climate change conditions in the PNW (including altered timing and amounts of hydropower exports to California) have little impact on reliability and prices in the California market -- unless compounded by climate change conditions in California. However, climate conditions in California have a significant impact on outcomes in the PNW, especially when compounded with shifts in the timing of PNW hydropower generation.

description: This study explored the awareness and utilization of artificial intelligence (AI) tools among secondary school students in Enugu North Local Government Area, Enugu State, Nigeria, specifically for learning Biology. Guided by two null hypotheses and four research questions, the study employed a descriptive survey design. The population consisted of 1,780 Senior Secondary School Class II (SS 2) students from nine secondary schools, with a purposive sample of 300 students (180 females, 120 males) from three coeducational schools. Data was collected using the "Awareness and Utilization of Artificial Intelligence Tools for Learning of Biology (AUAITLB)" instrument, validated by three education specialists, and with a reliability coefficient of 0.78. Descriptive statistics and t-test analysis revealed no significant gender differences in AI awareness and utilization. However, the study found that students underutilize AI tools like educational apps, virtual reality (VR), and augmented reality (AR). Recommendations include increased AI sensitization and greater use of AI tools by Biology teachers.

IL CONDIZIONAMENTO DEL DIRITTO EUROPEO SULL�ORGANIZZAZIONE PUBBLICA DEI SERVIZI ECONOMICI. STUDIO SUI LIMITI DERIVANTI DAL DIRITTO DELL�UNIONE EUROPEA ALLA DISCREZIONALIT� ORGANIZZATIVA, TRA AUTOPRODUZIONE ED ESTERNALIZZAZIONE
Creators: name: CARULLO, GHERARDO
Publisher: name: Universit� degli Studi di Milano
Year: 2015

description: The research focuses on the way in which European law influences the discretionary decisions of national Authorities in the organization of services of general economic interest (hereinafter referred to as ?SGEI?). In general terms, to ensure the European compatibility of a model of organization to be adopted to carry out a SGEI, it must be verified that the organizational formula chosen complies with the internal market. Various institutions of European law come into play, both of primary and secondary legislation: the rules on public tender procedures, the new legislation on the ?public contracts between entities within the public sector? (art. 12, Directive 2014/24/EU, and the similar provisions in Directives 2014/23/EU and 2014/25/EU), the case-law on public-private partnerships, and the rules on State aids. The phenomenon is particularly interesting since it involves immediate repercussions on the exercise of discretionary powers. The fact that National Authorities must act coherently with the internal market rules implies that the decisions taken on the organisation of SGEI must be consistent with such market. Therefore, all decisions must consider that the service will be provided in the context of a free economy and a pro competitive environment. This means that the decisions on the organisation of SGEI must always state the reasons on which they are based. In particular, it is necessary to clarify why the organizational model chosen is deemed viable having regard to the framework deriving from the European competition principles. As a consequence, a decision to adopt a given organizational model may be contested if no adequate reasons are given to support it. European competition principles may thus be relevant in a ?judicial review procedure?. In this context, the applicant could seek the annulment claiming that the choice made by the Public Authority has not been taken in accordance with the principle of proportionality, or that it is not sustainable in economic terms.

 2. Developing a landscape of curators, products and tools that steer people towards giving to G/RE
 3. To draw out conclusions and form recommendations based on the body of research and tools that exist, in order to inform the Philanthropic Partnerships Team’s strategy (eg what tools/approaches have been successful in steering people toward giving to these cause areas?, what motivates people to give to G/RE?)

description: We present a brief review of the teleparallel equivalent of general relativity and analyse the expression for the centre of mass density of the gravitational field. This expression has not been sufficiently discussed in the literature. One motivation for the present analysis is the investigation of the localization of dark energy in the three-dimensional space, induced by a cosmological constant in a simple Schwarzschild-de Sitter space-time. We also investigate the gravitational centre of mass density in a particular model of dark matter, in the space-time of a point massive particle and in an arbitrary space-time with axial symmetry. The results are plausible, and lead to the notion of gravitational centre of mass (COM) distribution function.

description: L’exposé d’Etienne Klein a bien mis en situation le traitement du temps et celui de l’irréversibilité des phénomènes physiques par les physiciens depuis Galilée jusqu’à Einstein. Partant de la relativité einsteinienne, je rappellerai dans la première partie de cet exposé quelques traits de la physique contemporaine qu’il faut avoir à l’esprit quand on parle du temps : la nécessité de l’espace-temps, sa structure ; j’utiliserai le voyageur de Langevin pour justifier l’introduction de la gravitation dans la relativité générale ; le contraste entre la loi de l’entropie croissante pour les systèmes isolés et la possibilité de systèmes auto-organisés pour les systèmes ouverts sera rappelé. Dans la seconde partie, l’absence du présent dans la théorie physique est abordée ; j’introduirai la philosophie de la nature d’Alfred North Whitehead, dont le point central concernant le temps est l’inexistence de l’instant. Malgré ses limites, cette philosophie de la nature ouvre des perspectives pour une métaphysique du temps compatible à la fois avec la mécanique quantique et la relativité. Elle a de plus le mérite de proposer une explication du présent et des mécanismes de passage de la potentialité à la réalité concrète.
HARVEY’S HOMELESS: DISASTER THROUGH THE EYES OF THE STREET

description: This thesis examines the impacts of Hurricane Harvey on the street homeless population of Houston, Texas and the subsequent disaster response coordinated by the City of Houston and Houston's Continuum of Care (CoC)—The Way Home. This photo-ethnographic study was conducted 18 months post-Harvey and followed a socio-ecological mixed methods approach. Using a political ecology theoretical orientation, the preliminary results are broken into three areas—"Disturbance Regimes”, “Disaster for whom?”, and “CoC Intervention”—to describe street homeless experiences of disaster and the coordinated disaster response. Based off these preliminary results, I argue that homeless individuals are conditioned to a disaster context making Harvey “like any other day.” Moreover, I assert that disaster can be viewed as an opportunity for homeless peoples as new pathways out of homelessness are created that did not exist pre-disaster. This orientation justifies increasing CoC funding and integration as a disaster preparedness measure.
Parametric Modulation of Dynamo Waves

description: Long-term variations of solar activity, including the Grand minima, are believed to result from temporal variations of dynamo parameters. The simplest approximation of dynamo waves is applied to show that cyclic variations of the parameters can lead to an exponential growth or decay of magnetic oscillations depending on the variations frequency. There is no parametric resonance in a dynamo, however: the selective sensitivity to distinct frequencies, characteristic of resonant phenomena, is absent. A qualitative explanation for this finding is suggested. Nonlinear analysis of dynamo-waves reveals the hysteresis phenomenon found earlier in more advanced models. However, the simplified model allows a computation of a sufficiently large number of dynamo-cycles for constructing the distribution function of their amplitudes to reproduce qualitatively two modes of solar activity inferred recently from cosmogenic isotope content in natural archives.

description: In this proceedings, I will consider quantum aspects of a non-local, infinite-derivative scalar field theory - a ${\it toy \, model}$ depiction of a covariant infinite-derivative, non-local extension of Einstein's general relativity which has previously been shown to be free from ghosts around the Minkowski background. The graviton propagator in this theory gets an exponential suppression making it ${\it asymptotically \, free}$, thus providing strong prospects of resolving various classical and quantum divergences. In particular, I will find that at $1$-loop, the $2$-point function is still divergent, but once this amplitude is renormalized by adding appropriate counter terms, the ultraviolet (UV) behavior of all other $1$-loop diagrams as well as the $2$-loop, $2$-point function remains well under control. I will go on to discuss how one may be able to generalize our computations and arguments to arbitrary loops.

Un Progetto di Rilevante Interesse Nazionale, finanziato dal Ministero dell’Università e della Ricerca nel 2017, sul tema dell’istruzione e dello sviluppo nel Sud Italia dall’Unità al 1914, ha messo a punto interrogativi circa l’incidenza dell’istruzione sullo sviluppo e la qualità della vita sociale nelle regioni meridionali e ha spinto le autrici del presente contributo – che sono anche ricercatrici in tale Progetto – a intersecare alcuni argomenti proposti in un volume di larga divulgazione: Italiani per forza. Le leggende contro l’Unità d’Italia che è ora di sfatare, di Dino Messina. Centrale, nel dibattito, è la questione economica, sociale, educativa. Ne scrivono, con accenti diversi e direzioni guidate dalle proprie pertinenti ricerche, Antonia Criscenti, Livia Romano (Il Risorgimento meridionale nella rappresentazione filmica), Silvia A. Scandurra (Come (non) ha funzionato l’istruzione tecnica e professionale), Giusy Denaro (La Sicilia nelle inchieste).

Although 160 years have passed since the unification of Italy, there is still a sharp economic and social gap between North and South of the country. Through a national research project aimed at investigating literacy conditions in southern Italian regions (PRIN 2017: Literacy and Development in Southern Italy from Italian Unification to the Giolittian Era. 1861-1914), the authors of this essay, starting from some stereotypes described in the book by Dino Messina, Italians forcefully, that have supported the reasons of one or the other part of the Country, try to explain the reasons for the gap between the North and the South of Italy. Discuss these topics in this essay Antonia Criscenti, Livia Romano (The Southern Risorgimento in the film), Silvia A. Scandurra (How technical and vocational education have (not) operated), Giusy Denaro (Sicily in the surveys).

The Effect of Fidesz Family Policy and Socioeconomic Factors on Fertility in Hungary
Creators: name: Hepburn, James Robert
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: This study evaluates the impact of expansions to family policy by the political party Fidesz on fertility in Hungary since 2010 and tests the effects of key socioeconomic and cultural characteristics on fertility in Central and Eastern Europe. To do so, we estimate difference in differences linear regression and Probit models for the recent birth of a child in households in 10 Central and Eastern European countries from 2002-18, and a Poisson model for the number of children given birth to by women in a subsample of these countries for 2006 and 2018. We introduce a partial theory of choice that provides an exhaustive set of mutually exclusive ways a person can choose to have a child to develop novel hypotheses. We find the policies modestly increased fertility initially but later had no significant effect, and that Roman Catholic, more traditional and less pleasure-seeking individuals tended to have more children.
ASSOCIATION BETWEEN IMU BASED ACCELEROMETRY ON THE TIBIA AND VERTICAL GROUND REACTION FORCE DURING DROP LANDING
Creators: name: Clapp, Aaron Seth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Peak vertical ground reaction force is a fundamental biomechanical variable often used to assess lower extremity injury risk. Currently, the tools to measure vGRF are not cost effective. Therefore, the purpose of this study is to determine the association between the variables related to IMU-based accelerometry and vGRF as measured from a research grade force-plate during a drop-landing task. Correlations were run on the averages of the 8 trials for peak vGRF to MVA and MMVAD in the right, left, dominant, and non-dominant limb. The non-dominant limb showed the greatest correlation of peak vGRF to MVA (r=0.803, p<0.01) and MMVAD (r=0.779, p<0.01). The dominant limb showed the lowest correlation of peak vGRF to MVA (r=0.573, p<0.01) and MMVAD (r=0.563, p<0.01). The strength of the association between accelerometry and vGRF during a drop landing may be limb dependent. The strongest associations between vGRF, MVA and MMVAD were in the non-dominant limb.
The precise time-dependent solution of the Fokker-Planck equation with anomalous diffusion

description: We study the time behavior of the Fokker-Planck equation in Zwanzig rule (the backward-Ito rule) based on the Langevin equation of Brownian motion with an anomalous diffusion in a complex medium. The diffusion coefficient is a function in momentum space and follows a generalized fluctuation-dissipation relation. We obtain the precise time-dependent analytical solution of the Fokker-Planck equation and at long time the solution approaches to a stationary power-law distribution in nonextensive statistics. As a test, numerically we have demonstrated the accuracy and validity of the time-dependent solution.

description: Le rôle computationnel des taux de décharge des neurones dans le traitement de l’information dans le cerveau semble aujourd’hui improbable, même si le principe de l’identité psychoneurale a conduit à de remarquables résultats pratiques. La détection de coïncidences, la mise en oscillation de territoires neuronaux, le calage de phase et/ou les avances de phase des émissions neuronales suggèrent l’utilisation par le cerveau d’un codage temporel précis. Ce codage, toutefois, ne vise peut-être pas à la description précise de l’environnement, mais plutôt à la caractérisation statistique des causes des stimulations reçues compte tenu des connaissances acquises, dans un traitement typiquement bayésien.
Biografia di un maestro valdostano

description: Partendo dall’infanzia e dalla sua esperienza come alunno in una pluriclasse di una scuola di un paesino di montagna, l’intervista ripercorre la storia personale e professionale di Germano Dionisi, un maestro elementare e formatore valdostano in pensione che, a partire dagli anni ‘ 70 del secolo scorso ha unito la professione educativa alla passione politica ed al sogno di contribuire a trasformare la società. Cruciale in questo senso è stato l’incontro con il Movimento di Cooperazione Educativa (MCE), con Mario Lodi e molti altri “maestri” capaci e carismatici, ma anche con Francesco De Bartolomeis e i suoi laboratori artistici all’Università di Torino. Nel testo la storia di vita si intreccia con la storia della scuola italiana e, in particolare valdostana, per circa un cinquantennio: dai Decreti delegati, alle riforme per l’inclusione scolastica, al ruolo fondamentale dell’IRRSAE (Istituto Regionale per la Ricerca e Sperimentazione Educativa) nella formazione in servizio degli insegnanti e nella innovazione didattica sull’intero territorio nazionale. Germano Dionisi, avendo svolto, a partire dagli anni ’90, il ruolo di formatore all’interno di tale istituto, ha anche modo di raccontare due importanti sperimentazioni condotte in Valle D’Aosta. L’intervista costituisce, quindi, una testimonianza coinvolgente ed emozionante su un periodo fondamentale della nostra scuola ma permette anche di riflettere criticamente sui cambiamenti avvenuti e sulla situazione attuale.

Starting from his childhood and his experience as a student in a multi-grade classroom in a small mountain village, the interview traces the personal and professional history of Germano Dionisi, a retired elementary school teacher and educator from the Valle D’Aosta, who, since the 1970s, combined his profession as teacher with his political passion and with the dream of transforming society. Crucial in this sense was his encounter with the Educational Cooperation Movement (MCE), with Mario Lodi and many other capable and charismatic “masters”, but also with Francesco De Bartolomeis and his artistic workshops at the University of Turin. In the text, the life story is intertwined with the history of the Italian school and, in particular, the Aosta Valley school, for about fifty years: from the delegated decrees, to the reforms for school inclusion, to the fundamental role of the IRRSAE (Regional Institute for Educational Research and Experimentation) in the in-service training of teachers and in didactic innovation in Italy. Germano Dionisi, having played, since the 90s, the role of trainer within this institute, also has the opportunity to tell about two important experiments conducted in his Region. The interview is, therefore, an engaging and emotional testimony on a fundamental period of italian school but also allows us to critically reflect on the changes that have occurred and on the current situation.

description: Describing individual morphology and growth is key for identifying ecological niches and monitoring the health and fitness of populations. Eastern North Pacific (ENP, approximately 16 650 individuals) gray whales primarily feed in the Arctic/sub-Arctic regions, while a small subgroup called the Pacific Coast Feeding Group (PCFG, approximately 212 individuals) instead feeds between northern California, USA and British Columbia, Canada. Evidence suggests PCFG whales have lower body condition than ENP whales. Here we investigate morphological differences (length, skull, and fluke span) and compare length-at-age growth curves between ENP and PCFG whales. We use whaling data from ENP whales (1959–1969) for comparison to data from PCFG whales collected through non-invasive techniques (2016–2022) to estimate age (photo-identification) and length (drone-based photogrammetry). We use Bayesian methods to incorporate uncertainty associated with morphological measurements (manual and photogrammetric) and age estimates. We find that while PCFG and ENP whales have similar growth rates, PCFG whales reach smaller asymptotic lengths. Additionally, PCFG whales have relatively smaller skulls and flukes than ENP whales. These findings represent a striking example of morphological adaptation that may facilitate PCFG whales accessing a foraging niche distinct from the Arctic foraging grounds of the broader ENP population.
Lengua e identidad de una generación intermedia: migrantes hispanohablantes en la universidad italiana
Creators: name: Sagi-Vela González, Ana
Publisher: name: Altre Modernità
Year: 2020

description: The reworking of new identities as a result of migratory movements is largely defined by the multilingual nature of the subjects. The adoption of the language of the host country, as an indispensable requirement for integration, together with the maintenance to a greater or lesser extent of the language of the country of origin characterizes the sociolinguistic profile of first and second generation migrants. This is a paradigmatic social phenomenon of continuity and disruption of the cultural background of individuals in contemporary societies. The present study addresses the role of language in shaping the identity of young people in a specific migration context: the Hispanic American population in Italy. In particular, will be analyzed the case of Spanish-speaking university students as representatives of an intermediate generation fully integrated in Italian society and that, at the same time, maintains a strong link with their cultural roots.

El arquitecto y el emperador de Asiria: Arrabal, el canibalismo y la imaginacion de América
Creators: name: Santos, Daniel
Publisher: name: Altre Modernità
Year: 2020

description: The objective of this work is to identify Fernando Arrabal’s play El arquitecto y el emPerador de ASiria (1966) as an allegory of colonialism and show how this is built upon some elements of the imaginacion de América (Miguel Rojas Mix). Specific tropes, among which are quoted the fountain of youth and the cannibalism, allow to place the play as a transatlantic text that dialogues whit the different discourses of the colonization of America, especially with the chronicles of the explorers of the colonial period. Likewise, different aspects of the American stereotype are updated in a parody of the ethnographic discourse, like the good savage and the acculturated.
