Collapse and Protein Folding: Should We Be Surprised that Biothermodynamics Works So Well?
Authors: Sosnick Tobin R. , Baxa Michael C.
Published: December 2024

A complete understanding of protein function and dynamics requires the characterization of the multiple thermodynamic states, including the denatured state ensemble (DSE). Whereas residual structure in the DSE (as well as in partially folded states) is pertinent in many biological contexts, here we are interested in how such structure affects protein thermodynamics. We examine issues related to chain collapse in light of new developments, focusing on potential complications arising from differences in the DSE's properties under various conditions. Despite some variability in the degree of collapse and structure in the DSE, stability measurements are remarkably consistent between two standard methods, calorimetry and chemical denaturation, as well as with hydrogen–deuterium exchange. This robustness is due in part to the DSEs obtained with different perturbations being thermodynamically equivalent and hence able to serve as a common reference state. An examination of the properties of the DSE points to it as being a highly expanded ensemble with minimal amounts of stable hydrogen bonded structure. These two features are likely to be critical in the broad and successful application of thermodynamics to protein folding. Our review concludes with a discussion of the impact of these findings on folding mechanisms and pathways.
Isotope Evolution of the Depleted Mantle
Authors: Vervoort Jeffrey D. , Kemp Anthony I.S.
Published: December 2024

The depleted mantle reservoir is that part of Earth's mantle from which crust has been extracted, leaving the remaining mantle depleted in incompatible elements. Knowing how and when it formed is essential for understanding the chemical evolution of Earth, including formation of continental crust. The best-constrained Hf isotope data presented here indicate that the mantle does not become significantly depleted until as late as 700 million years after Earth's accretion. This onset of mantle depletion coincides with the first appearance of substantial volumes of continental crust in the geological record. These data compel a revision to the reference depleted mantle parameters used in Hf isotope studies of planetary evolution. This new reference line follows chondritic evolution until 3.8 Ga and then describes a linear trajectory to a present-day depleted mid-ocean ridge basalt source mantle composition (εHf = +18). We infer that stabilization of continental crust only occurred in earnest on Earth after 3.8 Ga.

▪

Hf isotopes show that Earth's mantle does not become significantly depleted until 700 million years after planetary accretion.

▪

Most of Earth's oldest rocks formed from mantle sources that had radiogenic isotope compositions similar to those of chondritic meteorites.

▪

Isotope evidence shows that Hadean (>4.0-billion-year-old) crust was not essential for formation of younger crust in Archean terranes.

▪

Growth of Earth's continents only began in earnest after 3.8 Ga.
Harm Reduction: The Neglected Pillar of US Drug Policy
Authors: Saloner Brendan , Heller Daliah , Davis Corey S. , Sherman Susan G.
Published: December 2024

Harm reduction programs provide tools that enable people who use drugs to do so more safely in a nonstigmatizing environment without the goal of them necessarily seeking treatment or abstinence. Most harm reduction programs in the United States distribute sterile syringes and naloxone and safely dispose of used syringes and other drug use supplies. Many also provide drug checking services, and other safer use supplies. These programs exist on a limited scale and often face restrictions on their funding and scope of operations. While research demonstrates the effectiveness of existing programs in preventing infectious disease transmission and fatal overdose, there is less evidence about conditions that support the effective expansion and sustainment of existing models. Other harm reduction interventions such as overdose prevention centers and safer supply programs have promising international evidence but are prohibited or severely restricted under US law. In this review, we summarize the evidence for harm reduction interventions, describe the policy environment in which they exist, and provide recommendations to better align drug policy with existing and emerging evidence in the US context.
The Social Construction of Skill in International Migration: Perspectives from Asia
Authors: Liu-Farrer Gracia
Published: December 2024

Skill-based selective migration policies are a dominant contemporary form of migration governance in labor receiving countries. Researchers have critiqued these policies, noting discrepancies between their intended goals and the actual labor market outcomes for immigrants. The social construction of skill offers a sociological interpretation of this migration phenomenon, emphasizing that skills and their categorization in international migration are intrinsically political. Skills are socially constructed by actors in specific local, national, transnational, and global contexts. This article reviews scholarship that explores these dynamics from Asian perspectives. It identifies the various positions that countries in Asia occupy in skill mobility and highlights the critical issues related to both outbound and inbound skill migration in this region, as well as intraregional mobilities. The concluding section cautions against a reproduction of skill hierarchy in social science research and advocates a social construction approach to analyzing skill mobilities in different world regions.
Investigation of Soil Erodibility and Environmental Impact Assessment in Mining Project (Case Study: Tafresh, Markazi Province, Iran)
Authors: Hamidi Neda , Varvani Javad , Abdi Nourollah , Ahmadi Abbas
Published: December 2024

Purpose: The research examines the variation of soil erodibility index and physical characteristics due to iron placer mining activities and assesses the environmental impact of mining project by using MICOLD matrices.

Methods: The research employed field samplings, laboratory analysis, and statistical analysis to study the variation of soil erodibility index and physical characteristics caused by iron placer mining activities. The study collected soil samples from the study area and conducted laboratory analysis to examine the physical and chemical properties of the soil. Statistical analysis was performed to analyze the data and identify the variation in soil erodibility index compared to natural conditions. Also, by modifying ICOLD matrices, environmental impact assessment of the project was evaluated.

Results: The results of the paper indicate that there are significant differences between treated and untreated soils in terms of physical and chemical properties. The soil erodibility property (Ks) differs by −14.71% from natural conditions in top soils, although not significant statistically. In subsoil, Ks, clay, sand, Sp, Cu, Zn, Mn, Fe, and K differ significantly from untreated conditions (−43.38%, 35%, −15.07%, 5.28%, −192.50%, −242.55%, −101.86%, −333.34%, and −31.41%). The matrix of prediction and identification of the impacts related to the implementation of the mining project was created in two phases (construction phase and exploitation phase), the results of which show the total points in the construction phase and the exploitation phase have positive impacts and are equal to +71 and +171, respectively.

Conclusions: The study examines the effects of iron placer mining operations on soil erosion characteristics and erodibility and suggests environmentally friendly solutions for minimizing the effects of mining on soil erosion. The research findings highlight the importance of considering physical characteristics of soils such as texture, infiltration, bulk density, and soil erodibility in evaluating the performance and efficiency of any project implemented on the Earth’s surface. It emphasizes the need for designing well‐operated devices and structures with little environmental damage to promote eco‐innovation and green growth. The paper suggests that the environment is the most critical aspect of green surface mining, followed by efficiency and safety, and highlights the importance of microorganisms in mining environments and their role in constructing and producing primary succession for plant communities.
Taking the Name of the Lord in Vain in Early Modern Italy
Authors: Biasiori Lucio
Published: December 2024

Drawing from a rich array of sources, including trial records, sermons, and literary works, the essay investigates the ambiguities surrounding the definition and punishment of blasphemy in early modern Italy. The essay delves into the jurisdictional tensions between secular and ecclesiastical authorities in prosecuting blasphemers, the social identities of those accused of blasphemy, and the intertwining of blasphemy with other perceived vices, such as sodomy. The author also traces the gradual decriminalization of blasphemy, from its initial perception as a grave sin to its eventual marginalization as a bourgeois vice. Ultimately, the essay invites readers to reflect on the enduring relevance of the blasphemy debate in contemporary societies grappling with the tensions between freedom of expression and respect for religious beliefs.
Atlantic Slavery, the Catholic Church and Sanctity in the Early Modern Age
Authors: Delpiano Patrizia
Published: December 2024

New forms of enslavement surfacing on the world stage have spurred an international surge of studies in recent decades on the topic of slavery in general and Atlantic slavery in particular. Italian historiography on the Early Modern Age has actively contributed to this body of work and suggested various avenues of research fueled by different perspectives, from intellectual history to social history, from political history to gender and labor history. As is fitting considering Christian universalism, much attention has been granted to the religious dimension of the phenomenon. Various issues have been addressed, from the Catholic Church’s role and culture to the roles played by individual religious orders, from conversion practices used among slaves to the creation of the “African pantheon” featuring former slaves who became saints. Taken together, these studies have helped to add complexity to our understanding of the relationship between Catholicism and Atlantic slavery and call into question the separation between Mediterranean and Atlantic slavery, two worlds that are actually closely intertwined. A focused analysis of the relationship between slavery and sanctity, explored through the case of Jesuit Pedro Claver who was born in Catalonia in 1580, became a missionary overseas and died in Cartagena de Indias (New Kingdom of Granada) in 1654, is effective in demonstrating the spatial and temporal scope of these events. This extensive scope calls for longer-term reflections that go beyond the Early Modern Age and recognize the inextricable connections between religious and political history.
Religious Practices, Boundaries, and Institutions
Authors: Pavone Sabina , Villani Stefano
Published: December 2024

This introduction to the monographic issue highlights the methodological shift inspired by the “global turn,” which has reshaped traditional research fields by emphasizing interconnectedness across cultural and religious contexts. It examines how Italian religious historiography has engaged with global frameworks while maintaining a dialogue with its national traditions. The discussion addresses pivotal historiographical debates. The first section of the essay provides a general overview of religious history in Italian historiography since the late 1990s, followed by a more detailed exploration of the most recent historiographical developments and debates.

PURPOSE

Electronic health records (EHRs) comprise a rich source of real-world data for cancer studies, but they often lack critical structured data elements such as diagnosis date and disease stage. Fortunately, such concepts are available from hospital cancer registries. We describe experiences from integrating cancer registry data with EHR and billing data in an interoperable data model across a multisite clinical research network.

METHODS

After sites implemented cancer registry data into a tumor table compatible with the PCORnet Common Data Model (CDM), distributed queries were performed to assess quality issues. After remediation of quality issues, another query produced descriptive frequencies of cancer types and demographic characteristics. This included linked BMI. We also report two current use cases of the new resource.

RESULTS

Eleven sites implemented the tumor table, yielding a resource with data for 572,902 tumors. Institutional and technical barriers were surmounted to accomplish this. Variations in racial and ethnic distributions across the sites were observed; the percent of tumors among Black patients ranged from <1% to 15% across sites, and the percent of tumors among Hispanic patients ranged from 1% to 46% across sites. Current use cases include a pragmatic prospective cohort study of a rare cancer and a retrospective cohort study leveraging body size and chemotherapy dosing.

CONCLUSION

Integrating cancer registry data with the PCORnet CDM across multiple institutions creates a powerful resource for cancer studies. It provides a wider array of structured, cancer-relevant concepts, and it allows investigators to examine variability in those concepts across many treatment environments. Having the CDM tumor table in place enhances the impact of the network's effectiveness for real-world cancer research.
The Construction of Nuyorican Identity in the Art of Taller Boricua
Authors: Caragol Taína
Published: December 2024

In the late 1960s, diasporic Puerto Ricans established the Nuyorican movement, a sociocultural endeavor rooted in New York City to assert their presence and civil rights. El Taller Alma Boricua (Taller Boricua) was a pivotal institution that provided a platform for artists of color, aiming to create workshops and exhibition spaces absent from the mainstream. Artists like Marcos Dimas, Fernando Salicrup, Jorge Soto Sánchez, and Nitza Tufiño, members of Taller Boricua, sought to express their Puerto Rican identity within the context of diaspora. This essay employs the theories of Edward Said, Homi K. Bhabha, and Michael Seidel, to examine the visual vocabulary and conceptual strategies of these artists. This essay reexamines their work through a diasporic lens rather than exile aesthetics. The artists’ common traits included reinterpreting Taino culture as a symbol of Puerto Rican identity and critiquing colonial history.
The Politics and Poetics of Máximo Colón's Activist Photography
Authors: Ferrer Elizabeth
Published: December 2024

Máximo Rafael Colón, an artist and activist, captures the Puerto Rican community’s evolution in New York through a prolific photographic archive spanning five decades. Born in Arecibo, Puerto Rico, in 1950, Colón migrated to New York during the Great Migration. Despite language barriers, he found purpose in photography. Politically awakened during the 1960s, he joined BMCC’s Third World Coalition and documented social struggles, becoming a photographer for the leftist newspaper Prometheus. Colón joined El Comité, advocating for housing justice and Puerto Rican independence. He was part of a pioneering generation of Nuyorican photographers that emerged in the 1960s–1970s. His work captured social movements, revealing everyday heroes and fostering an ethos that photography itself is a political act. Colón’s legacy lies in his dedication to documenting his community’s journey and advocating for justice through the lens.
A Modernist Nuyorican Casita and the Aesthetics of Gentrification
Authors: Londoño Johana
Published: December 2024

The chapter explores the transformation of Nuyorican casitas, emblematic structures of South Bronx culture, into institutionalized objects. The Willis Avenue Community Garden’s casita, displayed at the Bronx Museum in 2014, embodies this shift. Originally a symbol of resistance against urban decay and marginalization, casita’s historical significance as a counterspace to modernist urban development has evolved. The NY Restoration Project (nyrp) replaced the original casita with a streamlined, modular version designed by a global architectural firm. This transformation reflects gentrification and aligns the casita with modernist aesthetics. The chapter demonstrates the process of de-politicization and de-contextualization, turning the casita into an aesthetic object detached from its cultural and social roots. The casita’s evolution serves as a lens to examine urban change, erasure, and gentrification’s impact on ethnic identity.

Το τραγικό προσωπείο στις παραστάσεις της αρχαιότητας και στην αναβίωση του αρχαίου δράματος στη νεότερη και σύγχρονη Ελλάδα
Authors: Μπαλτζώη Σοφία
Published: December 2024

Η διενεργούμενη έρευνα εξετάζει τη χρήση του τραγικού προσωπείου στις παραστάσεις της αρχαιότητας μέσα από τη μελέτη και ανάλυση των σωζόμενων αρχαιολογικών και φιλολογικών πηγών. Τα ερωτήματα που καλείται να απαντήσει το παρόν πόνημα σχετίζονται στο κύριο μέρος τους με την προέλευση, την κατασκευή, τη μορφή, την εξέλιξη και τη χρήση του τραγικού προσωπείου στο θέατρο της αρχαιότητας, ελληνικής και ρωμαϊκής. Έπειτα παρακολουθεί την αναβίωση του αρχαίου δράματος εν γένει στην Ευρώπη καθώς και στη νεότερη Ελλάδα. Μετά από ένα μεγάλο χρονικό κενό στη χρήση του προσωπείου, η έρευνα επικεντρώνεται στην επανεμφάνισή του στην αναβίωση του αρχαίου δράματος στις Δελφικές Εορτές από τον Άγγελο Σικελιανό και την Εύα Πάλμερ-Σικελιανού το 1927 και 1930 αντίστοιχα. Παράλληλα, διερευνάται η χρήση ή η μη χρήση του μετά τις Δελφικές Εορτές καθώς και στις σύγχρονες παραστάσεις αναβίωσης αρχαίου δράματος. Το θεωρητικό μέρος της έρευνας κλείνει με ένα αμιγώς πρακτικό και καλλιτεχνικό μέρος, το οποίο περιλαμβάνει την πειραματική ανακατασκευή και τη χρήση τραγικών προσωπείων στο πλαίσιο μιας πειραματικής-ερευνητικής παράστασης και μελετά την πρόσληψη από τις ηθοποιούς και από το κοινό.
Η εφαρμογή δέσμης μέτρων ως παρέμβαση ποιότητας στη μείωση του ποσοστού επιμόλυνσης καλλιεργειών αίματος και της επίπτωσης βακτηριαιμίας σε μονάδα εντατικής θεραπείας
Authors: Βεϊνή Φανή
Published: December 2024

ΕΙΣΑΓΩΓΗ: Η εφαρμογή μίας Δέσμης Μέτρων έχει σκοπό να μειώσει την επιμόλυνση των αιμοκαλλιεργειών. Η μελέτη αυτή εξέτασε προοπτικά την επίδραση από την εφαρμογή μίας Δέσμης Μέτρων στο ποσοστό επιμόλυνσης των αιμοκαλλιεργειών σε ΜΕΘ με υψηλό φόρτο εργασίας. ΣΚΟΠΟΣ: Σκοπός της μελέτης ήταν να ελεγχθεί η υπόθεση ότι η επιτήρηση και ανατροφοδότηση των αποτελεσμάτων των καλλιεργειών αίματος σε όλους τους εμπλεκόμενους στη Μονάδα Εντατικής Θεραπείας και η εφαρμογή «Δέσμης Μέτρων» σε συνδυασμό με εκπαίδευση του προσωπικού συμβάλλουν στη μείωση του ποσοστού επιμόλυνσης των αιμοκαλλιεργειών και της επίπτωσης της βακτηριαιμίας. Δευτερεύοντες σκοποί ήταν να καταγραφούν οι γνώσεις, στάσεις και πρακτικές των επαγγελματιών υγείας σχετικά με τον τρόπο λήψης αιμοκαλλιέργειας πριν και μετά την εφαρμογή της παρέμβασης, να καταγραφούν οι ενδείξεις λήψης αιμοκαλλιέργειας σε νοσηλευόμενους ασθενείς, να αναζητηθούν παράγοντες κινδύνου για βακτηριαιμία ή επιμόλυνση από την πλευρά του ασθενή. ΜΕΘΟΔΟΣ: Πρόκειται για μία προοπτική μελέτη πριν και μετά (before after study) η οποία διεξήχθη σε τρεις χρονικές περιόδους, μία περίοδο πριν την παρέμβαση, την φάση της παρέμβασης και τη χρονική περίοδο μετά την παρέμβαση. Οι αιμοκαλλιέργειες που ελήφθησαν χαρακτηρίστηκαν ως θετικές, αρνητικές, επιμολυσμένες και απροσδιόριστες. Χρησιμοποιήθηκε διμεταβλητή και ανάλυση διακοπτόμενων χρονοσειρών για την αξιολόγηση της επίδρασης της παρέμβασης και των παραγόντων που σχετίζονται με τα ποσοστά επιμόλυνσης. ΑΠΟΤΕΛΕΣΜΑΤΑ: Κατά τη διάρκεια της μελέτης συλλέχθηκαν συνολικά 4236 φιαλίδια ΑΜΚ. Το ποσοστό επιμόλυνσης μειώθηκε σημαντικά μετά την παρέμβαση από 6,2% σε 1,3%. Το ποσοστό επίπτωσης των επιμολυσμένων ΑΜΚ ήταν σημαντικά χαμηλότερο στη φάση μετά: 0,461 έναντι 0,154 sets ΑΜΚ ανά 100 ασθενοημέρες στη ΜΕΘ. Συνολική συμμόρφωση με τη χρήση της Δέσμης Μέτρων αυξήθηκε από 3,4% σε 96,9%. ΣΥΜΠΕΡΑΣΜΑΤΑ: Η εφαρμογή της Δέσμης Μέτρων ήταν αποτελεσματική στη μείωση του ποσοστού επιμόλυνσης των ΑΜΚ, αν και η μακροπρόθεσμη επίδραση του μέτρου δεν αξιολογήθηκε.
Artistic and photorealistic image style transfer using deep learning

Η μεταφορά στυλ είναι μια δημοφιλής τεχνική στην υπολογιστική όραση και την επεξεργασία εικόνας, που περιλαμβάνει τη δημιουργία μιας εικόνας που συνδυάζει το περιεχόμενο μιας εικόνας με το στυλ μιας άλλης ή μιας συλλογής εικόνων. Σε αυτή τη διατριβή, εξετάζουμε τους δύο κύριους τύπους μεταφοράς στυλ, δηλαδή την καλλιτεχνική και τη φωτορεαλιστική, οι οποίοι βρίσκουν εφαρμογές σε διάφορους τομείς, όπως ο σχεδιασμός βιντεοπαιχνιδιών, η ανάπτυξη εφαρμογών για κινητά και η αρχιτεκτονική. Η καλλιτεχνική μεταφορά στυλ αντιμετωπίζει την περίπλοκη πρόκληση της μεταφοράς του στυλ μιας συλλογής εικόνων σε μια δεδομένη εικόνα. Η προτεινόμενη μέθοδός μας περιλαμβάνει μια επέκταση της αρχιτεκτονικής Cycle-Consistent Adversarial Network, η οποία ενσωματώνει την ταχεία και Προσαρμοστική Δισδιάστατη Εμπειρική Αποδόμηση (FABEMD) στο πρόβλημα βελτιστοποίησης της ελαχιστοποίησης της συνάρτησης απώλειας. Αυτή η τροποποίηση επιτρέπει την ανάλυση των εικόνων στα βασικά τους υφή και παρέχει έναν ποιοτικότερο ορισμό της συνάρτησης απώλειας. Επιπλέον, προτείνουμε έναν μηχανισμό προσαρμοστικής επιλογής, ο οποίος περιλαμβάνει διαφορετικές ποσότητες φασματικής πληροφορίας (Bidimensional Intrinsic Mode Functions) ανάλογα με τα χαρακτηριστικά της εικόνας που υπόκειται σε στυλιζάρισμα. Σε αντίθεση με υπάρχουσες προσεγγίσεις, οι μέθοδοί μας μεταφέρουν το στυλ αποτελεσματικά και γρήγορα, χωρίς παραμόρφωση του περιεχομένου. Παρόμοια με την καλλιτεχνική, η φωτορεαλιστική μεταφορά στυλ ορίζεται ως η διαδικασία μεταφοράς του στυλ μιας εικόνας σε μια άλλη, διατηρώντας τον οπτικό ρεαλισμό. Μια δημοφιλής εφαρμογή αυτής της τεχνικής είναι η αναδημιουργία εικόνων με χαμηλό φωτισμό, στοχεύοντας στη δημιουργία της ίδιας εικόνας υπό κανονικές συνθήκες φωτισμού. Ωστόσο, οι υπάρχουσες μέθοδοι συχνά παρουσιάζουν χωρικές παραμορφώσεις, μη ρεαλιστικά τεχνουργήματα ή ανεπαρκώς αναπαραστημένα χρώματα, γεγονός που περιορίζει τη χρήση τους σε εφαρμογές που απαιτούν φωτορεαλιστικά αποτελέσματα. Για την αντιμετώπιση αυτού του προβλήματος, προτείνουμε μια νέα προσέγγιση που βασίζεται σε μια τροποποιημένη αρχιτεκτονική U-Net με πυκνά μπλοκ και κυματική συσσωμάτωση (wavelet-based pooling). Αυτή η αρχιτεκτονική σχεδιάστηκε για να διατηρεί καλύτερα τις περιοχές υφής κατά την ενίσχυση εικόνας και έχει αποδειχθεί αποτελεσματική και ανθεκτική σε σύγκριση με άλλες σύγχρονες μεθόδους μεταφοράς στυλ. Επιπλέον, προτείνουμε μια προσέγγιση συγχώνευσης (late fusion) δύο παράλληλων αρχιτεκτονικών U-Net, της HDD-Unet, για τον εμπλουτισμό της χρωματικής απόδοσης της τελικής παραγόμενης εικόνας. Για την αξιολόγηση των προτεινόμενων μεθόδων μας, τόσο για το πρόβλημα της καλλιτεχνικής όσο και της φωτορεαλιστικής μεταφοράς στυλ, συγκρίνουμε ποσοτικά και ποιοτικά τις μεθόδους μας με άλλες σύγχρονες τεχνικές. Τα αποτελέσματά μας αποδεικνύουν την αποτελεσματικότητα στη δημιουργία εικόνων με διατήρηση σημαντικών οπτικών πληροφοριών.
«Τα πάντα ρεῖ»: Η αμφίβολη ερμηνεία ενός ανύπαρκτου αποφθέγματος
Authors: Πέρρος-Αποστολόπουλος Παναγιώτης
Published: December 2024

Η αναδρομή στην κλασική ελληνική γραμματεία είναι ένα απαραίτητο συστατικό στοιχείο της ενδελεχούς επιστημονικής μελέτης στο χώρο των θεωρητικών, ανθρωπιστικών επιστημών και όχι μόνο. Εξαιρετικά σπάνια βρίσκει κανείς στη φιλοσοφία έννοιες οι οποίες δεν έχουν συναντηθεί πρωτίστως, ακόμη και σε σπερματική μορφή, στα αρχαία ελληνικά κείμενα. Για να προσεγγιστεί στην ολότητά του ένας φιλοσοφικός όρος, οφείλουμε να ανατρέξουμε στις καταβολές του, ώστε να τον διαλευκάνουμε εννοιολογικά σε πρωτογενές επίπεδο. Το ίδιο φυσικά συμβαίνει και σε επίπεδο γνωμικών και αποφθεγμάτων. Παρατηρείται συχνά να διατυπώνονται, τόσο στο δημόσιο λόγο όσο ακόμη και σε επιστημονικά πονήματα, αποφθέγματα και γνωμικά τα οποία είτε παραποιούνται μορφολογικά και εννοιολογικά είτε είναι απλώς ψευδεπίγραφα. Ορισμένα από αυτά ουδέποτε έχουν καταγραφεί στη σχετική πηγή, αλλά έχουν επικρατήσει στην ιστορία τόσο διά της καθομιλουμένης όσο και διά της ανεπίσημης γραπτής παράδοσης από ορισμένους, οι οποίοι διαιωνίζουν ένα σφάλμα. Μια τέτοια περίπτωση είναι το διάσημο, μα ψευδεπίγραφο, ρητό «τα πάντα ρεῖ». Για να κατανοήσουμε το σφάλμα στη βάση του, οφείλουμε αρχικώς να προσεγγίσουμε την ουσία της φιλοσοφίας του Ηρακλείτου, αλλά και της παρεμφερούς προσωκρατικής διανόησης, και ακολούθως να συμπεράνουμε επαγωγικά τόσο το σφάλμα όσο και την ορθή διατύπωση του φιλοσόφου.
«Τεχνουργημένη άγνοια, πολυμαθής ασυναρτησία»: η μέθοδος του Σλάβοϊ Ζίζεκ;

Published: December 2024

Προβεβλημένοι στοχαστές καλλιέργησαν μια «νέα φιλοσοφική» μέθοδο —η οποία κατ’ ουσία δεν είναι ούτε νέα ούτε φιλοσοφική: Χρησιμοποιώντας ενδείξεις ή ασύνδετα μεταξύ τους στοιχεία, αξιοποιώντας τη ζάλη ακατάσχετων παρεκβάσεων, μεταμφιέζοντας την επιθυμία σε επιστημονική γνώση, βαφτίζουν τις υποθέσεις τους συμπεράσματα. Κτίζοντας πάνω σε αυθαίρετους, αμετροεπείς ισχυρισμούς, διακινητές τέτοιων αντιλήψεων οδηγούνται στην αυτοεπιβεβαίωση της αρχικής τους παραδοχής. Συχνά, αυτό που εμφανίζεται ως αποδεδειγμένο συμπέρασμα δεν είναι παρά η αρχική υπόθεση, μασκαρεμένη με άλλα ρούχα. Η μέθοδος είναι κάθε άλλο παρά «νέα»: η προσφυγή στις σοφιστείες αποτελεί παιδική ασθένεια της φιλοσοφίας, προτού τη θεραπεύσει ο Σωκράτης. Κατόπιν, μάλιστα, της θεραπείας, αμφισβητείται κατά πόσο η ίδια αυτή προσέγγιση μπορεί να αποκληθεί «φιλοσοφική». Στο παρόν κείμενο διερευνάται η τυπολογία της μεθόδου που ακολουθεί ο Σλάβοϊ Ζίζεκ: εμφανίζει μία σχετικά εύλογη υπόθεση και —μέσω μιας πολύπλοκης αλληλουχίας ημι-αληθειών, αναληθειών και ψευδών— γενικεύει, οδηγώντας σταδιακά σε ένα ανυπόστατο ανορθολογικό συμπέρασμα.

Over the years piercing has become popular as a form of art and self-expression that may concern various areas of the body. However, it may pose significant risks to health. This literature review aims to provide insight into the matter of oral piercing and to examine recent studies investigating the implications of oral piercing on health. It emphasizes the necessity of promoting education regarding this matter and points out the most significant preventive measures such as regular dental examinations and maintaining proper hygiene that should be taken to minimize the negative consequences of oral piercing on health. 
The state of knowledge
According to the examined studies investigating the implications of oral piercing on health, a wide range of complications have been reported. Gingival recession, damage to dentition and gingivitis should be mentioned among the most frequently discussed. Moreover, studies have demonstrated a correlation between the severity of complications and the location of the piercing, specifying the adverse effects of the piercing within lip and tongue areas in particular. They have also underscored the impact of prolongated wear time on the risk of complications, indicating the elevated risk associated with extended periods of wear time.
 Conclusions
To minimize adverse effects of oral piercing on health, it is crucial to underscore the role of proper education in this field and the importance of taking preventive measures such as performing the piercing procedure by well qualified professionals who endure sterile work conditions and maintaining proper aftercare of the ornament. The role of regular dental examinations taken in order to detect and treat potential complications at early stages is also vital.
CARD SORTING FOR REMOTE RESEARCH
Authors: Renzi Adriano
Published: December 2024

This paper presents proceedings and structure to conduct card sorting as part of research strategies, based on studies from Padovani, Tullis & Wood, Maurer & Warfel and Preece. The research  proposes how to adapt card sorting appropriately to remote research working scenarios of the post-pandemic new century. This analytical study is based on two different information architecture structure research projects – an online learning search engine to help people find courses within enormous possibilities of learning subjects, and a co-living system, where people with similar interests gather and share living for communal learning experiences. Although the analysis is based on 2 real projects, this paper focuses mainly on card sorting procedures itself, without sharing too much information about the projects. The 2 projects helped to compare processes and results of representative user profiles and non-representative profiles to better understand the pain points, the advantages and disadvantages and the triggers to identify misleading information when conducting card sorting.

Published: December 2024

Introduction: In May 2020, the Brazilian Supreme Court ruled that men who have sex with men (MSM) should be eligible to donate blood. Objectives: This study aims to describe the epidemiological, sociodemographic, and serological profile of MSM donors in the haemotherapy centre of a university hospital. Methodology and Resources: A cross-sectional study was conducted between June 2020 and June 2023. The study was approved by the Ethics Review Board of the Pedro Ernesto University Hospital. Results: There was a predominance of young people, single, and with higher education (complete or incomplete). Regarding gender specification, 46 (92%) identified as cis. In the sample, 64% (32) of candidates had taken at least one rapid test in the 12-month period. Most of the individuals analysed were donor eligible (90%), non-reactive for the serology of interest in the research (91.3%). Discussion: Among MSM donors, the prevalence of homosexual orientation and the regular use of condoms were observed. Even with the prior restriction of Resolution No. 399/2020, a proportion of these candidates donated blood. The reactivity for syphilis (6%) among the volunteers is below expectations, while for hepatitis B (2%) it is above the target, considering that the indicator presented by the state blood bank network, and there was no HIV reactivity. Conclusions: The importance of using risky sexual behaviour, rather than sexual orientation, as a criterion for donor eligibility was observed. This change allowed for the possibility of including minorities in the blood donation process.

Relação entre dieta vegetariana, comer transtornado e imagem corporal em adolescentes
Authors: Stavro Adriana Paula Giacomelli , Ganen Aline de Piano
Published: December 2024

Objetivo: Avaliar a relação entre dieta vegetariana, comer transtornado e imagem corporal em adolescentes. Métodos: Estudo transversal realizado em duas escolas privadas, localizadas no município de São Paulo, com 204 adolescentes, idade entre 15 anos e 18 anos e 11 meses. A avaliação da imagem corporal em meninos foi realizada pelo Male Body Dissatisfaction Scale versão curta, enquanto que nas meninas utilizou-se o Body Shape Questionnaire. Avaliou-se o comportamento alimentar transtornado pela Escala de Atitudes Alimentares Transtornadas para Adolescentes versão curta em ambos os sexos. Os indivíduos que indicaram não aderir a uma dieta vegetariana compuseram o grupo controle. Realizou-se análise estatística de acordo com comportamento das variáveis. Resultados: 92,2% da população estudada foi composta por onívoros, sendo apenas 7,8% da amostra vegetariana. Na análise dos escores médios de insatisfação corporal e comer transtornado, não houve diferença entre os tipos de dieta, embora o comer transtornado tenha sido significativamente maior entre meninas. Observou-se correlação moderada entre o comer transtornado e a insatisfação com a imagem corporal em toda a população feminina e entre vegetarianas; já nos meninos, a correlação foi fraca entre essas variáveis e apenas presente quando considerada toda a população masculina. Conclusões: A frequência de vegetarianismo e de comportamentos do comer transtornado não diferiu entre vegetarianos e onívoros. Observou-se, no entanto, relação entre o comer transtornado e insatisfação com a imagem corporal em meninas, sobretudo entre as vegetarianas, reforçando a importância de mais investigações nesta população.
Disfagia: elementos na fala de idosos hospitalizados com risco nutricional
Authors: Ferreira Ronivaldo Pinto , Marsicano Alves Luana , Davison Mangilli Laura
Published: December 2024

Introdução: A associação entre disfagia e desnutrição pode ser explicada pelo fato de que a disfagia prejudica diretamente a capacidade de comer e beber, reduz a ingestão alimentar de energia, água e outros nutrientes, resultando em desnutrição e desidratação. Uma habilidade que poderá contribuir na identificação de risco para disfagia e/ou desnutrição é a escuta sensível, qualificada e resolutiva dos idosos em ambiente hospitalar. Objetivo: Identificar elementos na fala de idosos hospitalizados com alteração nutricional que possam contribuir para o rastreio de disfagia. Métodos: Pesquisa quali-quantitativa com a técnica de análise de conteúdo, realizada com 52 idosos internados em unidade de clínica médica de um hospital público no Distrito Federal, com aplicação do Mini Nutritional Assessment shortform e da pergunta norteadora sobre engolir. Resultados: Maior frequência de risco de desnutrição (63,46%), tendo na fala a questão relacionada ao uso de prótese dentária mal adaptada, a consistência da dieta oral ofertada, o engasgo e o processo de envelhecimento como fatores que podem interferir no estado nutricional e favorecer o risco para disfagia. Conclusão: É preciso que esses fatores modificáveis sejam identificados pela equipe de saúde e que ações para o tratamento e prevenção eficazes de desnutrição e de disfagia sejam implantados e monitorados.

Authors: Pereira Diego Henrique Costa , Gomes Roberto Arnaldo Trancoso , Júnior Osmar Abílio de Carvalho , Guimarães Renato Fontes
Published: December 2024

A legislação brasileira permite a garimpagem de ouro embarcada em rios desde que possua Permissão de Lavra Garimpeira emitida pela Agência Nacional de Mineração que demanda o prévio licenciamento ambiental. Dessa forma, o presente estudo tem como objetivo identificar procedimentos para melhorar a compreensão e o controle da atividade garimpeira a partir de sua caracterização, avaliação dos principais marcos regulatórios, levantamento do uso de sensoriamento remoto para identificação de garimpos embarcados, análise da distribuição geográfica e ocorrência da atividade. Ao fim, concluiu pela necessidade de adequação de instrumentos regulatórios, aprimoramento da atuação das instituições responsáveis pela emissão das devidas autorizações, fortalecimento das ações de combate à atividade ilegal e fiscalização das atividades legalizadas e desenvolvimento de políticas públicas adequadas à realidade. Da mesma forma, demonstrou que o uso de insumos e técnicas de sensoriamento remoto apresentam potencial para auxiliar no melhor controle da atividade.
heliana conde, a presença
Authors: Edson Passetti
Published: December 2024

O texto homenageia Heliana Conde, no contexto do evento "Modulações Helianas", realizado em 26 de junho de 2024, na UERJ. Heliana nunca gostou de atalhos ou do brilho superficial dos certificados. Preferia o avesso, a surpresa, o imprevisto. Professora, pesquisadora, militante, botafoguense, Heliana era aliada da resistência, da estética da existência, nunca da filantropia ou da normalização. Sua tese, No rastro dos “cavalos do diabo”, revela o percurso da psicologia institucional no Brasil, costurando memórias, histórias orais e encontros improváveis. Com Foucault, Deleuze, e os argentinos exilados, reinventou o pensamento grupal, sempre em diálogo com a liberdade. Heliana é a presença escondida, um rastro que permanece. Não queria melhorar nada, mas atiçar, vagar, flutuar, espalhar-se – como quem sabe que é no insustentável que mora a potência.

Escritas helianas: a leitura, as reticências, o riso.
Authors: Mizoguchi Danichi Hausen
Published: December 2024

O presente artigo advém de apresentação realizadas no encontro Modulações Helianas: docência, militância, escrita, realizado na Universidade do Estado do Rio de Janeiro, no dia 26 de junho de 2024. Interessado pela escrita de Heliana Conde, o texto evoca dois eixos analíticos para fazer aparecer, em especial, duas marcas da produção da intelectual brasileira recentemente falecida: a leitura e o riso. Tomando como intercessores autores como Michel Foucault, Giorgio Agamben, Umberto Eco e Roberto Machado, trata-se de posicionar eticamente o gesto da escrita heliana a partir de uma filosofia da pontuação e de um uso dos prazeres.

Militantismos de um coração selvagem
Authors: Aguiar Katia
Published: December 2024

Mais uma vez Heliana nos chama. Um chamado a compor, a estar junto, a dizer a verdade. Foi com ela e por ela que aceitamos, comparecemos e dissemos de nossas impressões, relevos e nervuras, no compartilhar das varrições de uma vida. Depois do encontro presencial que se fez evento, pensado e proposto por um cuidadoso arranjo afetivo, depois de estarmos juntas/os a celebrar, partilhando o dia (o seu dia de aniversário) com tantas e diversas histórias, penso que se terá confirmado o que sempre foi desafio em suas convocações: o desafio de coletivizar na diferença. Entre tantos, entretantos, e tantos entres... curiosa possibilidade de sustentar amizades tão diversas, tão ímpares, por vezes antagônicas em suas posições.
