description: One of the major challenges of contemporary mathematics is numerical solving of various problems for functional differential equations (FDE), in particular Cauchy problem for delayed and neutral differential equations. Recently large variety of methods to handle this task appeared. In the paper, we present new semi-analytical approach for FDE's consisting in combination of the method of steps and a technique called differential transformation method (DTM). This approach reduces the original Cauchy problem for delayed or neutral differential equation to Cauchy problem for ordinary differential equation for which DTM is convenient and efficient method. Moreover, there is no need of any symbolic calculations or initial approximation guesstimates in contrast to methods like homotopy analysis method, homotopy perturbation method, variational iteration method or Adomian decomposition method. The efficiency of the proposed method is shown on certain classes of FDE's with multiple constant delays including FDE of neutral type. We also compare it to the current approach of using DTM and the Adomian decomposition method where Cauchy problem is not well posed.

description: We report a quantum magnetotransport signature of a change in Fermi surface topology in the Rashba semiconductor BiTeI with systematic tuning of the Fermi level $E_F$. Beyond the quantum limit, we observe a marked increase/decrease in electrical resistivity when $E_F$ is above/below the Dirac node that we show originates from the Fermi surface topology. This effect represents a measurement of the electron distribution on the low-index ($n=0,-1$) Landau levels and is uniquely enabled by the finite bulk $k_z$ dispersion along the $c$-axis and strong Rashba spin-orbit coupling strength of the system. The Dirac node is independently identified by Shubnikov-de Haas oscillations as a vanishing Fermi surface cross section at $k_z=0$. Additionally we find that the violation of Kohler's rule allows a distinct insight into the temperature evolution of the observed quantum magnetoresistance effects.

description: Cuminol (4-Isopropylbenzyl alcohol), found in the essential oils of several plant sources, is an important constituent of several cosmetics formulations. The interaction of cuminol with model plasma protein bovine serum albumin was studied in this paper. The experimental studies were mainly carried out using fluorescence spectrophotometry aided with UV visible and CD spectroscopies. Intrinsic fluorescence measurements showed that there was a weak binding between cuminol and BSA. The mechanism of binding involved static quenching with around 1:1 binding. The binding was chiefly supported by hydrophobic forces although a little contribution of hydrogen bonding was also found in the interaction and the values of enthalpy change were negative with positive entropy change. The secondary structure of BSA didn’t change significantly in presence of low concentrations of cuminol, however, partial unfolding of the former taken place when the concentration of the latter increased. Molecular docking analyses showed cuminol binds at the intersection of subdomains IIA and IIIA, i.e. its binding site is in between Sudlow sites I and II. Molecular dynamics simulations results have shown that BSA forms a stable complex with cuminol and the structure of the former didn’t change much in presence of later. Communicated by Ramaswamy H.

description: As more written language data become available, the interest in written language mixing / codeswitching (LM/CS) is increasing (Sebba, Mahootian & Jonsson 2012; Sebba 2013). LM/CS in non-naturalistic (e.g., literary) texts raises issues related to gauging (1) the authenticity and representativity of a textual corpus, and deciding (2) whether categories/mechanisms of spoken LM/CS apply to written LM/CS. We focus on Guarani-Spanish LM/CS (Jopara) as represented in the Paraguayan novel Ramona Quebranto (RQ). We apply the framework of Muysken (1997; 2000; 2013), developed as a taxonomy of spoken LM/CS. Our contribution extends its applicability to written LM/CS. We show that Jopara has a mix of insertional and backflagging strategies, with infrequent alternations.

description: In a centralized RAN, the signals from multiple RAPs are processed centrally in a data center. Centralized RAN enables advanced interference coordination strategies while leveraging the elastic provisioning of data processing resources. It is particularly well suited for dense deployments, such as within a large building where the RAPs are connected via fibre and many cells are underutilized. This paper considers the computational requirements of centralized RAN with the goal of illuminating the benefits of pooling computational resources. A new analytical framework is proposed for quantifying the computational load associated with the centralized processing of uplink signals in the presence of block Rayleigh fading, distance-dependent path-loss, and fractional power control. Several new performance metrics are defined, including computational outage probability, outage complexity, computational gain, computational diversity, and the complexity-rate tradeoff. The validity of the analytical framework is confirmed by comparing it numerically with a simulator compliant with the 3GPP LTE standard. Using the developed metrics, it is shown that centralizing the computing resources provides a higher net throughput per computational resource as compared to local processing.

description: Rationale: The aromatase inhibitor formestane (4‐hydroxyandrost‐4‐ene‐3,17‐dione) is included in the World Anti‐Doping Agency's List of Prohibited Substances in Sport. However, it also occurs endogenously as do its 2‐, 6‐ and 11‐hydroxy isomers. The aim of this study is to distinguish the different isomers using gas chromatography/electron ionization mass spectrometry (GC/EI‐MS) for enhanced confidence in detection and selectivity for determination. Methods: Established derivatization protocols to introduce [2H9]TMS were followed to generate perdeuterotrimethylsilylated and mixed deuterated derivatives for nine different hydroxy steroids, all with 3‐keto‐4‐ene structure. Formestane was additionally labelled with H218O to obtain derivatives doubly labelled with [2H9]TMS and 18O. GC/EI‐MS spectra of labelled and unlabelled TMS derivatives were compared. Proposals for the generation of fragment ions were substantiated by high‐resolution MS (GC/QTOFMS) and tandem mass spectrometry (MS/MS) experiments. Results: Subclass‐specific fragment ions include m/z 319 for the 6‐hydroxy and m/z 219 for the 11‐hydroxy compounds. Ions at m/z 415, 356, 341, 313, 269 and 267 were indicative for the 2‐ and 4‐hydroxy compounds. For their discrimination the transition m/z 503 → 269 was selective for formestane. In 2‐, 4‐ and 6‐hydroxy steroids loss of a TMSO radical takes place as cleavage of a TMS‐derived methyl radical and a neutral loss of (CH3)2SiO. Further common fragments were also elucidated. Conclusions: With the help of stable isotope labelling, the structures of postulated diagnostic fragment ions for the different steroidal subclasses were elucidated. 18O‐labelling of the other compounds will be addressed in future studies to substantiate the obtained findings. To increase method sensitivity MS3 may be suitable in future bioanalytical applications requiring discrimination of the 2‐ and 4‐hydroxy compounds.

description: In order to track the moving objects in long range against occlusion, interruption, and background clutter, this paper proposes a unified approach for global trajectory analysis. Instead of the traditional frame-by-frame tracking, our method recovers target trajectories based on a short sequence of video frames, e.g. $15$ frames. We initially calculate a foreground map at each frame, as obtained from a state-of-the-art background model. An attribute graph is then extracted from the foreground map, where the graph vertices are image primitives represented by the composite features. With this graph representation, we pose trajectory analysis as a joint task of spatial graph partitioning and temporal graph matching. The task can be formulated by maximizing a posteriori under the Bayesian framework, in which we integrate the spatio-temporal contexts and the appearance models. The probabilistic inference is achieved by a data-driven Markov Chain Monte Carlo (MCMC) algorithm. Given a peroid of observed frames, the algorithm simulates a ergodic and aperiodic Markov Chain, and it visits a sequence of solution states in the joint space of spatial graph partitioning and temporal graph matching. In the experiments, our method is tested on several challenging videos from the public datasets of visual surveillance, and it outperforms the state-of-the-art methods.

description: The scientific interest of the deposit, the perfect state of preservation of the palaeontological finds whose fossilization was favoured by the volcanic sediments in which they were embedded and the variety of their position - from bones transported and dislocated by waters to those in anatomical connection within the marshy area - motivated the implementation of a project for the musealisation of the site. The museum, realized on the occasion of the Jubilee 2000, allowed to preserve the deposit in situ, to enhance it and make it accessible to the public. The site museum project has been in progress for some years and is progressing through various phases of intervention. To allow an immersion in the Pleistocene landscape and to restore form and life to the innumerable remains of the many species visible on the paleosurface, two large panels have been created, placed on the internal walls of the building. The animals depicted in the foreground are life-size, almost in contact with the paleosurface that shows their bones, with the intention of creating a huge window that opens onto the biodiversity of 300,000 years ago. As part of the enhancement and promotion of the Museum, in 2017 a competition was launched for primary and secondary schools in Rome aimed at creating the new official Logo of the Museum, which ended with two exhibitions set up at the Museo Nazionale Romano and, in collaboration with the XIII Municipality, at Villa Carpegna, headquarter of the Quadriennale di Roma. At the end of 2022, the didactic apparatus was renewed with new panels and a short film that reconstructs the formation of the deposit in 3D, while the preparation of a different lighting that enhances the paleosurface is still underway. Other more extensive projects are planned in the short term in order to promote and enhance the value of this unique deposit. In particular, a new arrangement of the green area surrounding the museum, a parking area for visitors, a didactic area destined to various audiences, laboratories for the study and conservation of materials, open to the public have been planned. In this new phase, particular attention has been paid to visitors with disabilities, in order to offer better conditions of use and make the Museum more inclusive.

description: En este trabajo, presentaré una justificación del deber de investigar que tienen los Estados en tiempos normales y de emergencias de salud pública, en este caso motivada por la pandemia de COVID-19. Defenderé que el deber de investigar se corresponde con el derecho a la ciencia en tiempos normales, y cuando no exista una alternativa efectiva razonable para tratar una enfermedad o necesidad de salud relevante, también con el derecho a la salud. Mi principal hipótesis será que el deber de investigar es una obligación moral perfecta especial y distributiva. A su vez, desarrollaré las obligaciones que este deber supone para un Estado antes, durante y después de la investigación clínica, lo que aplicado al caso argentino incluye una Ley Nacional de Investigación Biomédica. Finalmente, intentaré responder algunas objeciones relativas a la investigación con seres humanos, a saber, la impermisibilidad moral de la investigación, el desperdicio de recursos al investigar en pandemia, la minimización de estándares en contextos de emergencia y la irrelevancia estatal.

description: We report here the highest resolution near-IR imaging to date of the HD 141569A disc taken as part of the NICI Science Campaign. We recover 4 main features in the NICI images of the HD 141569 disc discovered in previous HST imaging: 1) an inner ring / spiral feature. Once deprojected, this feature does not appear circular. 2) an outer ring which is considerably brighter on the western side compared to the eastern side, but looks fairly circular in the deprojected image. 3) an additional arc-like feature between the inner and outer ring only evident on the east side. In the deprojected image, this feature appears to complete the circle of the west side inner ring and 4) an evacuated cavity from 175 AU inwards. Compared to the previous HST imaging with relatively large coronagraphic inner working angles (IWA), the NICI coronagraph allows imaging down to an IWA of 0.3". Thus, the inner edge of the inner ring/spiral feature is well resolved and we do not find any additional disc structures within 175 AU. We note some additional asymmetries in this system. Specifically, while the outer ring structure looks circular in this deprojection, the inner bright ring looks rather elliptical. This suggests that a single deprojection angle is not appropriate for this system and that there may be an offset in inclination between the two ring / spiral features. We find an offset of 4+-2 AU between the inner ring and the star center, potentially pointing to unseen inner companions.

Guarani morphology in Paraguayan Spanish: Insights from code-mixing typology
Creators: name: Estigarribia, B.
Publisher: name: John Hopkins University
Year: 2017

description: In this paper we examine the use of Guarani affixes and clitics in colloquial Paraguayan Spanish. We depart from the traditional view of these as "borrowings," and instead explore the idea that these phenomena can be integrated within Muysken's (2000, 2013, 2014) typology of code-mixing. We claim that most of these uses may stem from a strategy of backflagging that bilingual speakers employ to mark their use of a (historical, colonial) L2 (Spanish) with elements from the original community L1 (Guarani). In so doing, however, we identify some problematic areas in applying Muysken's model to these data. We conclude by showing how this perspective shift in the analysis of Guarani-Spanish contact phenomena can both increase our understanding of this particular contact situation, as well as of code-mixing typology.

Ρόλος ο οποίος δεν αναγνωρίζεται, και αποτελεί καθημερινή́, δύσκολη και επιβαρυντική σε προσωπικό και κοινωνικό επίπεδο και επιπλέον αποτελεί απλήρωτη μορφή εργασίας. Η ψυχική καταπόνηση των ατόμων, που έχουν επιφορτιστεί τη φροντίδα χρονίως πασχόντων, εκδηλώνεται με δυσμενείς μεταβολές στην πλειονότητα των τομέων της ζωής, όπως επίσης και στην ψυχοσωματική υγεία και στην ποιότητα της ζωής τους εν γένει. (Glasdametal., 2010, Soubhietal.,2006). Σκοπός: Η παρούσα εργασία έχει ως στόχο να διερευνήσει την επιβάρυνση που μπορεί να προκληθεί από την συνεχομένη φροντίδα χρόνιων ασθενών στους άτυπους φροντιστές σε επίπεδο ψυχολογικής καταπόνησης και σε ότι αυτό συνεπάγεται για την υγεία και την ποιότητα ζωής τους.

Guaraní-Spanish Jopara mixing in a Paraguayan novel: Does it reflect a third language, a language variety, or true codeswitching?
Creators: name: Estigarribia, B.
Publisher: name: Brill Academic Publishers
Year: 2015

description: We study the highly idiosyncratic case of Paraguay, the only American nation where an indigenous language has survived as a majority language spoken by the non-indigenous population. Jopara is the name of the commonly used code that mixes Guaraní and Spanish. Characterizations of Jopara in the literature are inconclusive. Some authors call it a variety of Spanish, some a variety of Guaraní, others a new mixed language. The choice of one characterization over the other has important implications for the status of Guaraní vis-à-vis Spanish, especially for Paraguay's educational and language planning. Here we analyze Jopara as it is represented in the novel Ramona Quebranto (RQ-Jopara). We show that this written code is not a variety of either Spanish or Guaraní, nor a mixed language. Rather, it reflects properties of true code-switching. It displays both insertional and alternational characteristics (Muysken, 2000), as well as evidence of a composite matrix language (Myers-Scotton, 2002). We conclude by suggesting RQ-Jopara fits best a "mixed lect" scenario (Backus, 2003) and discussing generalization to spoken Jopara.

Ενώ σε παγκόσμιο επίπεδο υπάρχει ένα αυξανόμενο πεδίο έρευνας σχετικά με την ποιότητα ζωής που σχετίζεται με την υγεία ένα χρόνο μετά τη χειρουργική θεραπεία για μη μεταστατικό καρκίνο του μαστού, οι πληροφορίες που αφορούν Ελληνίδες ασθενείς είναι λιγοστές. Σκοπός: Σκοπός της παρούσας μελέτης ήταν η αποτύπωση της ποιότητας της ζωής γυναικών με καρκίνο του μαστού κατά το πρώτο εξάμηνο μετά τη διάγνωση, καθώς και η εξέταση παραγόντων που επιδρούν σε αυτή. Το δείγμα μελετήθηκε και 6 μήνες μετά την θεραπεία για την καταγραφή της πορείας και της πρόγνωσης της νόσου μετά από την συναίνεση των γυναικών για την συστηματική παρακολούθηση της θεραπείας τους. Εν συνεχεία τα ερωτηματολόγια εισήχθησαν σε πρόγραμμα στατιστικής ανάλυσης και αναλύθηκαν σχετικώς. Υλικό και Μέθοδος: Το εργαλείο συλλογής δεδομένων της παρούσας έρευνας είναι το ερωτηματολόγιο. Αποτελείται από δύο ενότητες. Η πρώτη ενότητα αποτελείται από 9 ερωτήσεις κλειστού τύπου, οι οποίες σχετίζονται με κοινωνικό δημογραφικά και ιατρικά στοιχεία (ηλικία, οικογενειακή κατάσταση, μορφωτικό επίπεδο, επαγγελματική κατάσταση, στάδιο διάγνωσης νόσου, είδος χειρουργικής αφαίρεσης όγκου, και πραγματοποίηση ακτινοθεραπειών, ορμονοθεραπειών και χημειοθεραπειών). Η δεύτερη ενότητα αφορά το γενικό ερωτηματολόγιο εκτίμησης της ποιότητας ζωής EORTCQLQ- C30 και ΕΟRΤC QLQ – ΒR23. Τα ερωτηματολόγια διανεμήθηκαν αρχικά τον Σεπτέμβριο του 2021 και στη συνέχεια η δεύτερη μελέτη των περιστατικών έγινε τον Μάρτιο του 2022. Το επίπεδο στατιστικής σημαντικότητας ορίζεται σε 0,05. Αποτελέσματα: Ο μέσος όρος ηλικίας του δείγματος είναι 45,5 έτη (ΤΑ=13,41). Το 22% είναι άγαμοι και το 78% είναι παντρεμένοι. Όλες έχουν ελληνική εθνικότητα. Το 47% είναι απόφοιτοι δευτεροβάθμιας εκπαίδευσης και το 53% είναι απόφοιτοι τριτοβάθμιας εκπαίδευσης. Το 70% εργάζονται και το 30% δεν εργάζονται. Στην αρχή διάγνωσης της νόσου οι ασθενείς έχουν καλύτερη ποιότητα ζωής στη φυσική, συναισθηματική, γνωστική, κοινωνική και λειτουργικότητα ρόλου. Στην αρχή της νόσου η καλύτερη λειτουργικότητα ήταν η φυσική και έξι μήνες μετά τη διάγνωση η καλύτερη λειτουργικότητα ήταν η γνωστική.

description: A definitive determination of the progenitors of type Ia supernovae (SNIa) has been a conundrum for decades. The single degenerate scenario $-$ a white dwarf (WD) in a semi-detached binary system accreting mass from its secondary $-$ is a plausible path; however, no simulation to date has shown that such an outcome is possible. In this study, we allowed a WD with a near Chandrasekhar mass of $1.4M_\odot$ to evolve over tens of thousands of nova cycles, accumulating mass secularly while undergoing periodic nova eruptions. We present the mass accretion limits within which a SNIa can possibly occur. The results showed, for each parameter combination within the permitted limits, tens of thousands of virtually identical nova cycles where the accreted mass exceeded the ejected mass, i.e. the WD grew slowly but steadily in mass. Finally, the WD became unstable, the maximal temperature rose by nearly two orders of magnitude, heavy element production was enhanced by orders of magnitude and the nuclear and neutrino luminosities became enormous. We also found that this mechanism leading to WD collapse is robust, with WDs in the range $1.0 - 1.38M_\odot$, and an accretion rate of $5*10^{-7}M_\odot/yr$, all growing steadily in mass. These simulations of the onset of a SNIa event make observationally testable predictions about the light curves of pre-SN stars, and about the chemistry of SNIa ejecta.

Julián Castro’s Ambivalent Dream
Creators: name: Vigil, Ariana
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Despite the title of his memoir, An Unlikely Journey: Waking Up from My American Dream, it is difficult to determine precisely what is unlikely about Julian Castro’s political life. Indeed, Castro’s pains to explain his own political commitments and aspirations in relationship to those of his parents, and in particular his mother, run the risk of portraying his political career as almost inevitable. Yet it would grossly misread the life of the former mayor of San Antonio and recent contender for the Democratic nomination for president to approach him as political royalty or as someone whose racial and economic background facilitated a smooth entrance into political life. Instead, Castro’s difficulty in speaking of his individual success in relation to his working-class, Mexican American family and community is one of the principal conflicts in the narrative.
A Journey to/through Family: Nostalgia, Gender and the American Dream in Reyna Grande’s The Distance Between Us

Year: 2019

description: The US- Mexico border is a prominently contested site not just of nationality and migration but also of history, memory, and identity: a heterotopia of fl uctuating meaning and status that imparts scars, both physical and psychic, upon individuals and families. Reyna Grande's memoir The Distance Between Us (2012) explores this multidimensional space through her family's experiences of separation, deprivation, and longing. In addition, the specter of La Llorona raises gendered transgressions and threats; the folk figure pushes back against idealizations of motherhood while also illustrating the consequences for women who do not fulfill these ideals. In this essay we consider the way that gender impacts Grande's separation from, and relationship with, her mother and father.

description: Melka Kunture is a cluster of Pleistocene sites discovered in 1963, located 50 km south of Addis Ababa on the Ethiopian highlands. Since then, annual archeological research has always involved a number of local workers from the nearby village of Awash. This collaboration led to the development of a team of workers specialized in archeological investigations. Meanwhile, a deep sense of pride and awareness also developed the local community at large, that has borne fruits in terms of recognition and protection of the archeological site. A small museum was built and eventually expanded, and some archeological areas were also left open for visitors. The candidature of the site to World Heritage List will be discussed by the UNESCO Committee in 2024. Expectations run high in the Awash community, which proudly recognizes the archeological site as a means to improve the importance and visibility of the area.

The Visionary Power of Chicana Girls in Virginia Grise’s blu
Creators: name: Vigil, Ariana
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: In the Introduction to his first influential book, Disidentifications: Queers of Color and the Performance of Politics, José Esteban Muñoz recalls two moments, one from his own childhood and one from Marga Gomez’s performance Marga Gomez is Pretty, Witty, and Gay. In both moments, the two queer Latinx youth watch and process the representation of queer people on mainstream U.S. television. While cognizant of how they are meant to understand the queer subjects, the youth are also able to repurpose what they are viewing for their own identificatory purposes. Speaking of Gomez’s reworking of her childhood memory in her performance, Muñoz writes: “the phobic object, through a campy over-the-top performance, is reconfigured as sexy and glamorous, and not as the pathetic and abject spectacle that it appears to be in the dominant eyes of heteronormative culture” (3). This reconfiguration provides the basis for Muñoz’s concept of disidentification, which he defines as “survival strategies the minority subject practices in order to elide a phobic majoritarian public sphere” (ibid, 4). In this case, young Gomez and Muñoz work to respond to and exist within a racist, misogynist and homophobic public sphere. Muñoz explains that disidentification may take place both inside and outside the dominant public sphere and that performances of disidentification often circulate within “subcultural circuits” (ibid, 5). While Muñoz’s theory has proved pivotal to contemporary Latinx, queer, and feminist studies, the specific moments in which he grounds the act of disidentification here are also significant because of their relevance to young people in particular. These moments in his and Gomez’s life situate the act of disidentification not only in the practices of queers of color, but more specifically in the practices of queer youth of color. As such, Muñoz’s ideas are particularly powerful for youth and suggest the importance of considerations of age in approaches to the work of queer and feminist artists of color.
Heterosexualization and the State: The Poetry of Gloria Anzaldúa
Creators: name: Vigil, Ariana
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: This paper examines how several poems by the late Gloria Anzaldúa offer a compelling portrait of the role of sexuality in relationship to colonialism, neocolonialism, and state formation. Through a reading of “We Call Them Greasers,” “Cervicide,” and “Yo no fuí, fue Teté,” the essay argues that Anzaldúa pinpoints how heterosexualization and heterosexism have been violently imposed on the bodies and psyches of Chicanas and Chicanos in the service of Anglo and patriarchal social, political, and economic hegemony. Considering these works in relationship to contemporary Chicana and Latina feminist theory, I demonstrate that Anzaldúa’s poetry, an under-studied aspect of her work and thought, takes up questions of gender, violence, and sexuality from a perspective that connects processes of racialized heterosexualization from the Conquest to our present moment.

description: Layered transition metal trichalcogenides with the chemical formula $ABX_3$ have attracted recent interest as potential candidates for two-dimensional magnets. Using first-principles calculations within density functional theory, we investigate the magnetic ground states of monolayers of Mn- and Cr-based semiconducting trichalcogenides. We show that the second and third nearest-neighbor exchange interactions ($J_2$ and $J_3$) between magnetic ions, which have been largely overlooked in previous theoretical studies, are crucial in determining the magnetic ground state. Specifically, we find that monolayer $\text{CrSiTe}_3$ is an antiferromagnet with a zigzag spin texture due to significant contribution from $J_3$, whereas $\text{CrGeTe}_3$ is a ferromagnet with a Curie temperature of 106 K. Monolayers of Mn-compounds ($\text{MnPS}_3$ and $\text{MnPSe}_3$) always show antiferromagnetic Neel order. We identify the physical origin of various exchange interactions, and demonstrate that strain can be an effective knob for tuning the magnetic properties. Possible magnetic ordering in the bulk is also discussed. Our study suggests that $\text{ABX}_3$ can be a promising platform to explore 2D magnetic phenomena.

The end(s) of representation: media and activism in Cherrie Moraga's Heroes and Saints
Creators: name: Vigil, Ariana
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: This essay focuses on the character of Ana Pérez in Cherríe Moraga's 1992 play Heroes and Saints, situating Pérez, a journalist, within contemporary US Latina/o literary and media studies. In the play, Pérez functions as a Malinche-like figure as she performs translative acts between the local protesters and her viewing audience. Her character gestures to the important role that Latina/o journalism may play in countering the mainstream Anglo media's often one-dimensional coverage of Latina/o communities and issues. However, Pérez's evolving role from translator to activist also acknowledges the limitations of media access, and in this sense the play illustrates Hector Amaya's concept of the “Latino public sphere paradox,” which questions the assumed positive relationship between access to media and access to political power. This essay offers a new perspective on an important piece of twentieth-century Chicana/o literature, focusing on an aspect of the play—media representation—that has received little attention. It demonstrates that research into the portrayal of media, especially journalism, in Chicana/o and Latina/o literature is productive and necessary.

description: The magnetoelectricity of garnets is considered by means of a symmetry and quantum mechanical combined analysis. It is shown, that the magnetoelectric effect is not realized in most garnets although the necessary condition of the crystal magnetic structure antisymmetry in them is held at low temperatures. Nevertheless, the effect can be observed in some garnets as well as other odd effects, namely, piezomagnetic effect, magnetic field evoked piezoelectric one, etc. It is also discovered that magnetic fields can induce specific antiferroelectric structures in garnet crystals and produce electric polarization in epitaxial films. The polarization can also be caused in a bulk crystal by an inhomogeneous magnetic field.

description: Home is a central and contested emotional, imagined and physical location that is meaningful for every person. Using personal narratives and scholarly essays, this special issue works through the negotiations of history and belonging with topics from sexuality, immigrant status, ethnicity, and religion to class. The volume features personal reflections by Évelyne Trouillot, Lisa Outar, and Isis Semaj-Hall and critical essays by April Shemak, Lyneise Williams, Belinda Deneen Wallace, and Tanya L. Shields. Each contributor considers the implications of complicated homes, identities, and geographies—particularly the Caribbean and US South—and provides new shadings on this always relevant issue by juxtaposing the personal and the academic.
