Un ciclo de mejora en la enseñanza de Historia Antigua de Asia Oriental
Authors: Albuquerque Pedro
Published: December 2024

Este CIMA es parte de la asignatura de Historia Antigua de Asia Oriental. Se
desarrolló durante 30 horas (septiembre-noviembre de 2023). Los asuntos tratados fueron, principalmente, una introducción a la Arqueología y sus problemas,
evolución humana, el poblamiento paleolítico de Asia Oriental, y la transición hacia las primeras sociedades agrícolas y primeras sociedades complejas en China,
Corea y Japón. El cuestionario previo pretendía caracterizar el estado de los conocimientos del alumnado, destacando su percepción sobre el trabajo de los
arqueólogos, yacimientos conocidos, la utilidad de la Arqueología para el conocimiento del pasado de Asia Oriental, así como el efecto del eurocentrismo en
la interpretación de las culturas asiáticas. Estas cuestiones se repitieron en un
cuestionario final con el objetivo de evaluar la evolución de las competencias del
alumnado. Los resultados fueron satisfactorios, lo que demostró la pertinencia de
dedicar algunas horas a una introducción general a la Arqueología.

Las ideas previas: clave del éxito. Ciclo de Mejora en el Aula para estudiantes del Grado en Educación Primaria
Authors: Durán-Guerrero Estrella
Published: December 2024

Se presenta un Ciclo de Mejora en el Aula (CIMA) desarrollado en la asignatura
de Psicología del Desarrollo en el primer curso del Grado en Educación Primaria.
Esta experiencia de innovación utilizó la reflexión de ideas previas y el trabajo
cooperativo para favorecer un aprendizaje significativo mediante la participación
activa del alumnado. Se emplearon escaleras de aprendizaje para evaluar la metodología implementada. Para ello, se administró el mismo cuestionario al inicio
y al final del CIMA a cada estudiante. La baja asistencia a las sesiones teóricas dificultó el seguimiento del CIMA, si bien, el alumnado que acudió tanto a las sesiones teóricas como a las prácticas, mostró mejores resultados en su escalera
de aprendizaje. Futuras adaptaciones deberán reconsiderar la calendarización del
CIMA e intentar reducir las faltas de asistencia durante su implementación.
Fani popkultury na lekcji języka obcego: Glottodydaktyczny potencjał fanfiction
Authors: Pudo Dorota
Published: December 2024

The aim of this monograph is to present the potential of fanfiction in teaching and learning foreign languages. Fanfiction is one of the most popular practices of the global fandom, i.e. the community of fans mainly centred around phenomena related to popular culture. The analysis focuses on virtual fan environments where stories set in fictional worlds of popular culture are created and shared, often in non-native languages. Writing these amateur literary texts requires the mobilisation of the very skills often taught in formal education: mastery of linguistic resources, including in foreign languages, as well as the ability to plan, edit, and proofread texts. The educational potential of fanfiction is considered in two ways: in the context of informal language learning through the creation, reading, and commenting of fanfiction on fan websites, and as a tool for use in formal education.
Learning to Be Fair: A Consequentialist Approach to Equitable Decision Making
Authors: Chohlas-Wood Alex , Coots Madison , Zhu Henry , Brunskill Emma , Goel Sharad
Published: December 2024

In an attempt to make algorithms fair, the machine learning literature has largely focused on equalizing decisions, outcomes, or error rates across race or gender groups. To illustrate, consider a hypothetical government rideshare program that provides transportation assistance to low-income people with upcoming court dates. Following this literature, one might allocate rides to those with the highest estimated treatment effect per dollar while constraining spending to be equal across race groups. That approach, however, ignores the downstream consequences of such constraints and, as a result, can induce unexpected harm. For instance, if one demographic group lives farther from court, enforcing equal spending would necessarily mean fewer total rides provided and potentially more people penalized for missing court. Here we present an alternative framework for designing equitable algorithms that foregrounds the consequences of decisions. In our approach, one first elicits stakeholder preferences over the space of possible decisions and the resulting outcomes—such as preferences for balancing spending parity against court appearance rates. We then optimize over the space of decision policies, making trade-offs in a way that maximizes the elicited utility. To do so, we develop an algorithm for efficiently learning these optimal policies from data for a large family of expressive utility functions. In particular, we use a contextual bandit algorithm to explore the space of policies while solving a convex optimization problem at each step to estimate the best policy based on the available information. This consequentialist paradigm facilitates a more holistic approach to equitable decision making.

Schistosomal appendicitis: A serious and often misdiagnosed condition
Authors: Nguyen Phi Duong , Lam Thanh Kien
Published: December 2024

Schistosomal appendicitis (SA) is a rare but serious complication of schistosomiasis, a parasitic disease affecting over 250 million people worldwide. A recent retrospective study by Wang et al provides important insights into the clinicopathological characteristics of SA. The study compared 136 cases of SA to 5418 cases of non-SA over a ten-year period. Key findings include a higher average age of SA patients (61.73 years vs 35.8 years for non-SA), a higher proportion of acute on chronic appendicitis (33.1% vs 16%), and a significantly higher incidence of colorectal cancer (11.7% vs 2.2%). Despite these differences, SA remains a diagnostic challenge due to its nonspecific clinical presentation and lack of specific laboratory findings. The study also highlights the persistent prevalence of SA, accounting for 1.6%-3.4% of all appendicitis cases each year from 2013 to 2023. These findings underscore the need for enhanced awareness, early detection, and prompt treatment of SA in endemic regions. Given the association with colorectal cancer, patients with SA require thorough screening and follow-up. Further research into the pathogenesis and diagnostic markers of SA is warranted. As the global battle against schistosomiasis continues, targeted efforts to diagnose and manage SA can significantly improve patient outcomes.
Role of pancreatic juice cytology in diagnosis of high-grade pancreatic intraepithelial neoplasia
Authors: Okasha Hussein Hassan , Tag-Adeen Mohammed , Shaaban Hossam Eldin
Published: December 2024

High-grade pancreatic intraepithelial neoplasia is a challenging diagnosis and it does not exhibit mass lesions. It is suspected based on changes in the main pancreatic duct in magnetic resonance cholangiopancreatography. Sometimes only an unclear duct shows in magnetic resonance cholangiopancreatography with no focal strictures and upstream dilatation of the main pancreatic duct. Serial pancreatic juice cytology is valuable in diagnosis of those patients.

Mujer negra y discurso plástico en Santiago de Cuba
Authors: Dublín Mercedes Cuesta , Coloma Yaneidys Arencibia
Published: December 2024

El artículo analiza la obra de pintores santiagueros que tienen a la mujer negra en sus discursos con el objetivo de determinar el condicionamiento social de su representación plástica, tomando la obra de pintores desde una micro localización geográfica distante del centro cultural de la isla (Santiago de Cuba). Se aplicó el método iconográfico para el análisis de las obras y se emplearon técnicas de análisis documental y de recogida de información para arribar a las consideraciones aquí expuestas. El estudio, desde las coordenadas de los Estudios Culturales y la Sociología del Arte, conduce a reconocer que, aunque la representación del individuo de piel negra en la plástica cubana ha cambiado los códigos visuales a lo largo de más de tres siglos, aún persisten estereotipos femeninos y raciales en el imaginario nacional y esto es representado con mayor frecuencia en el microcircuito de las artes plásticas santiagueras.
If You Want to Publish, Be Part of the Process

Published: December 2024

No abstract available. Manuscript truncated after 150 words. The edifice of academic journals is predicated on the process of peer review. Inevitably it is subject to the vagaries of the individual perspectives and biases of the reviewers. However, there has not been a useful, equitable or viable alternative that would secure a level of quality control in the research domain (1). Given the inevitable human components of range of knowledge, potential biases and sometimes lazy thinking, it is certainly not a perfect system. Certainly, a worthy paper occasionally is rejected, or a badly flawed paper is accepted. However, in the absence of a better process, it is the gold standard.
Historically, peer review has been an altruistic endeavor. Researchers understood that their reviews contributed to the scientific process by improving the quality of reported information and providing an imprimatur to the reported findings (2); reviewing was an obligation to the scientific community (3). However, there are other benefits …
Putting Port Royal on the Map: Jean de Labat's Early-18th-Century Cartographic Construction of Port Royal
Authors: Lapierre Carli
Published: December 2024

Abstract: Les cartes géographiques sont autant des images de fantaisies impériales que des sources de renseignements géographiques pratiques. Le travail de Jean de Labat, un ingénieur militaire français à Port-Royal, offre un cas d'espèce des expériences cartographiques impériales dans le nord-est de l'Amérique du Nord. Une lecture critique élargie de deux de ses cartes révèle que les réalités sur le terrain se mêlaient aux fantaisies impériales dans la construction d'une version de la vie à Port-Royal qui profitait à Labat et à d'autres fonctionnaires français. C'est pour ces raisons que le travail de Labat fut publié plus tard dans l'édition de 1727 des Cartes marines . Abstract: Maps are as much images of imperial imaginings as they are sources of practical geographic information. The work of Jean de Labat, a French military engineer at Port Royal, offers a case study of cartographic experimentation with empire in northeastern North America. An expanded critical cartographic reading of two of his maps reveals that on-the-ground realities mingled with imperial imaginings to construct a version of life at Port Royal that benefitted Labat and other French officials. It was for these reasons that Labat's work was later published in the 1727 edition of the Cartes marines .

Résumé: Par cette étude, en nous appuyant sur l'examen du Discours sur l'Afrique de Victor Hugo ( Actes et paroles IV - Depuis l'exil 1876–1885 , chapitre 23) nous allons aborder le thème de la perception eurocentriste de la Méditerranée dans le contexte colonial en France et nous nous proposons de démontrer quels sont les enjeux de l'image de soi et d'autrui dans l'interprétation eurocentriste-française de la ' civilisation '. Aussi focaliserons-nous sur l'utopie d'un 'colonialisme pacifique' en Méditerranée dans une optique de recréation culturelle.
Empty Center: Reflexive Modernity, Nostalgia, and the Mediterranean Relation
Authors: Hofmann Franck , Messling Markus
Published: December 2024

Abstract: The concept of the Méditerranée as a cultural centrality has collapsed in the catastrophic history of Europe. Attempts to restore the supposed unity of the Mediterranean are a hopeless endeavour. The power of a retrograde hope for renewal based on the spirit of a Mediterranean model is since long fading. Europe's relationship to its predestined philosophical location is being reshaped not only in the arts of our present, but already in the literary thinking of the Mediterranean during the colonial interwar period. This new relationship, which we seek to analyse here, is characterized by cultural difference and decentration, a nostalgic reference to the world and human solidarity. In the face of the violence of Modernity, the heritage and contemporaneity of the Méditerranée as a landscape of crisis are revised. It thus appears as a territory of experience and reflection in which, following the collapse of European humanism, the question of mankind and his/her symbolic forms and cultural practices is posed anew, particularly in minor forms like the essay, micro-histories and montages.
À l'attaque! Robert Guédiguian's Meta-Referential Cinema of Mediterranean Friendship and Solidarity
Authors: Winkler Daniel
Published: December 2024

Abstract: Robert Guédiguian's cinema comes across, on several levels, as a practice of solidarity. His works have been built on a close and unusually stable cinematographic community over decades. This social practice of filming is connected with a content-related political orientation that can be understood as having a Marxist foundation. If one defines friendship as the practice of living in solidarity, which connects familial bonds to their living environment and the world, then the two tendencies of a local and collective-historical exploration of friendship observed here can undoubtedly be noted in Guédiguian's work, which spans five decades. Looking at Guédiguian's oeuvre, it is striking that friendship is not only closely linked to a political understanding of the world but also to the Mediterranean region. As the son of an Armenian father and a German mother, themes of historical exile and contemporary migration from the Mediterranean play an important role in many of his Marseille films. Against this background, I contend that Guédiguian's cinema not only negotiates social practices of friendship and solidarity, it also brokers notions of belonging to the Mediterranean region. In this article I will elucidate Guédiguian's understanding of Mediterranean friendship. To this end so, I will focus on the unusually optimistic and playful film, À l'attaque! (2000), which has been often overlooked internationally. This film negotiates Mediterranean friendship as a solidary, sensual principle of life—not through a spatial opening of l'Estaque but in the form of a conte, in other words, through numerous transmedial references.
La Méditerranée pour les enfants-hôtes: (De Télémaque à Joann Sfar)
Authors: Benhaïm André
Published: December 2024

Résumé: Cet essai propose d'esquisser un début de réflexion sur la place des enfants dans les représentations poétiques (les fictions) de la situation d'hospitalité, individuelle et collective, dans le contexte spécifique de la Méditerranée. Cette réflexion pourrait se développer sur deux axes principaux : non seulement pour contempler le rôle que jouent les enfants en tant qu'objets de représentation et sujets de la situation d'hospitalité ; mais aussi pour se demander comment ils deviennent eux-mêmes un public à qui s'adresse certaines œuvres pour « expliquer » l'hospitalité (et la Méditerranée). À travers la figure homérique de Télémaque et une partie des bandes dessinées de Joann Sfar, c'est la figure de l'enfant-hôte qui est invoquée, dans tous les sens du terme, celui reçoit (tant bien que mal) et celui qui est reçu.

199 nm VUV coherent light emission from ultracompact SrB4O7 vertical microcavity pumped with picosecond laser
Authors: Nambu Tomoaki , Yoshimura Masashi , Mori Yusuke , Fujiwara Yasufumi , Ishii Ryota , Kawakami Yoichi , Uemukai Masahiro , Tanikawa Tomoyuki , Katayama Ryuji
Published: December 2024

We have developed highly efficient microcavity wavelength conversion devices that are adaptable to crystals lacking birefringence or ferroelectricity. In this study, we employed a low birefringence paraelectric SrB4O7 crystal, which exhibits significant potential for wavelength conversion and high transparency down to 130 nm. Using this crystal, we successfully achieved 199 nm vacuum-ultraviolet second harmonic generation with a picosecond laser. The achieved wavelength of 199 nm is shorter than the theoretical minimum of 205 nm for second harmonic generation in BaB2O4. Our device holds promise as a practical solution for vacuum-ultraviolet second harmonic generation, potentially enabling the development of significantly smaller and more efficient vacuum-ultraviolet laser sources compared to conventional systems.

Amplification of narrow linewidth 2-wavelength light for THz wavelength conversion
Authors: Takeya Kei , Yahia Vincent , Ishizuki Hideki , Taira Takunori
Published: December 2024

In generation of high-intensity terahertz (THz) waves, the difference frequency generation (DFG) method is a promising approach, but there are challenges such as wavelength selection of the excitation light, spectral width, and the scaling of the light source. To address these issues, we used a degenerate optical parametric system with a multiple reflection Bragg diffraction grating (VBG) to convert the 1064 nm light from an Nd:YAG micro MOPA into two wavelengths, 2126 nm and 2130 nm, with a linewidth of less than 1 nm. We also confirmed the generation of THz waves using this light and demonstrated the amplification of these two wavelengths using PPMgLN.

Fishmeal (FM) is a key component of commercial fish feeds, but due its unsustainable supply, the search for quality alternatives of FM has become a significant area of investigation worldwide. The insect-based proteins such as black soldier fly larvae (BSFL) are being recognized as an alternative ingredient. However, anti-nutritional factors in these alternatives may negatively affect nutrient utilization in fish. Incorporating exogenous protease enzymes as feed additives could be a promising way to improve the digestibility of these alternative ingredients. Therefore, this study aimed to evaluate the impact of dietary inclusion of BSFL meal, combined with protease supplementation, on various parameters of striped catfish (Pangasius hypophthalmus). Five diets were formulated: a control diet (FM-based), two diets with 30% and 60% BSFL inclusion (BSF30 and BSF60), and two diets with the same inclusion levels plus the incorporation of exogenous protease (BSF30P and BSF60P). One hundred fifty fish (8.26±0.02 g) were arbitrarily allocated to five groups, each with three replicates. The fish were provided with their respective diets twice per day for 60 days. In comparison to the control, fish-fed diets supplemented with protease demonstrated statistically significant lower levels of feed conversion ratio and higher growth performance regarding the final body weight and weight gain. Lipase activity in the BSF60P group was notably greater than in the control group. Protease supplementation significantly enhanced the apparent digestibility coefficient of protein, intestinal protease activity, and crude protein content in the whole body. Most hematological and biochemical parameters remained unaffected except for substantially lower triglyceride and cholesterol levels in the highest BSFL inclusion groups. These groups also showed a reduction in crude fat contents. While glutathione peroxidase and malondialdehyde levels did not change significantly from the control, the liver tissues of fish fed BSF60P diets showed considerably higher levels of antioxidant enzymes such as catalase and superoxide dismutase. The findings suggest that including 60% of a BSFL based diet, along with exogenous protease supplementation, is feasible without compromising the growth performance and health of striped catfish.
Cybercrime victimisation among older adults: A probability sample survey in England and Wales
Authors: Havers Benjamin , Tripathi Kartikeya , Burton Alexandra , McManus Sally , Cooper Claudia
Published: December 2024

Background

Younger people are more likely to report cybercrime than older people. As older people spend more time online, this may change. If similarly exposed, risk factors including social isolation and poor health could make older adults disproportionally susceptible. We aimed to explore whether cybercrime risks and their predictors vary between age groups.

Methods

We analysed responses from 35,069 participants aged 16+ in the 2019/20 Crime Survey for England and Wales (CSEW). We investigated, among people who have used the internet in the past year, risks of experiencing any cybercrime, repeat victimisation and associated financial loss across age groups.

Results

Despite being at lower risk of reporting any cybercrime in the past year, people aged 75+ were more likely to report financial loss resulting from cybercrime victimisation (OR 4.25, p = 0.037) and repeat cybercrime victimisation (OR 2.03, p = 0.074) than younger people. Men, those from Mixed or Black ethnic groups, more deprived areas, managerial professional groups, and with worse health were at greater cybercrime risk.

Discussion

While younger adults are more at risk from cybercrime, older adults disclosed more severe cases (repetitive victimisation and associated financial loss), perhaps due to lesser awareness of scams and reporting options. As most people experience declining health as they age, greater understanding of why poor health predicts cybercrime could inform prevention initiatives that would particularly benefit older age groups and mitigate risks of growing internet use among older adults. Health and social care professionals may be well positioned to support prevention.

Millions of Americans endure post-COVID conditions (PCC), yet research often lacks pre-illness measurements, relying primarily on follow-up assessments for analysis. The study aims to examine the prevalence of PCC, including cognitive impairment, functional limitation, and depressive symptoms, along with relevant risk factors, while controlling for individuals’ pre-illness status measured in 2018. A cross-sectional retrospective study utilized the 2018 and 2020 Health and Retirement Study surveys. Sample included individuals with COVID-19 (n = 409; average age 64) and individuals without COVID-19 (n = 8689; average age 59). COVID-19 positive: Individuals with positive tests, physician diagnoses, emergency room visits, or hospitalizations for COVID-19 between 2019–2020. Cognition was assessed using immediate and delayed word-recall tests, serial seven subtractions, and backward counting. Functional status was measured using limitations in activities of daily living (ADLs) and instrumental ADLs. Depressive symptoms were measured using the modified Center for Epidemiology Studies Depression scale. Participants’ perception of experiencing PCC was collected. Logistic regression and propensity score matching were employed for these analyses. Among 409 COVID-19-positive respondents (14% hospitalized), 24% exhibited new impairments after COVID-19 infection. Noteworthy increases in functional limitation (OR [95% CI]: 2.18 [0.95, 0.97], p < 0.001) and a marginal rise in cognitive impairment (1.79 [0.99, 3.32], p = 0.053) following COVID-19 infection were observed in comparison to their pre-COVID-19 baseline. Compared to 8689 non-COVID-19 cases, the 409 COVID-19 positives showed increased functional decline (1.78 [1.26, 2.51], p = 0.001) and depressive symptoms (1.41 [1.04, 1.91], p = 0.03). Factors associated with PCC included pre-existing impairments, lower education, female gender, prior hospitalization, higher comorbidity, lower wealth, and mild COVID-19. A notable number of respondents, especially older individuals with fewer pre-existing health conditions, experienced PCC without awareness. Compared to an individual’s pre-illness baseline and uninfected individuals, being positive for COVID-19 raised the risk of functional limitation, depressive symptoms, and cognitive impairment. Additionally, addressing PCC through both subjective and objective approaches is essential to alleviate individual and societal burdens.
‘The Moving Canvas Project’: Exploring choreography and disobedient drawing
Authors: Hubbard Jenna , Keeley Adele
Published: December 2024

These images and supporting paper presented by Hubbard and Keeley offer new insights relating to the relationship between movement, drawing, textiles and choreography. ‘The Moving Canvas Project’ is a participatory research project with an adult community dance company where the dancers explore the act of drawing and moving simultaneously. This emergent knowledge is underpinned by theoretical frameworks, in drawing performance, costume design and movement improvisation. The paper discusses a series of workshops where the process of creating textile design for costume and choreography for performance occurred concurrently. The authors present a balanced evaluation of the outcomes, sharing several observations regarding behaviour, performance and the overall aesthetic that emerged when dancers were asked to wear plain cream-coloured jumpsuits and draw on them whilst moving. It explores what influence the two disciplines had on each other and how dancers played with autonomy and collectivism as they drew on themselves and one another. The transient nature of movement creates a dissonance with the permanence of the drawing, which is left as a mark on the dancer’s disobedient bodies. It is within this dynamic interplay between movement and mark-making that a performance emerged.
The Independent Group: Working-class culture and collage
Authors: Massey Anne
Published: December 2024

The history and work of the Independent Group, this important collective of creative practitioners which met from 1952 to 1955, has recently attracted unprecedented levels of attention. However, within the fields of architectural, art and design history, the issue of social class is largely absent in recent work and oversimplified in twentieth-century accounts. This is despite the recent increase in class analysis being applied to the British creative and university sectors. Using Potvin and Marchand’s methodology of agency and the work on social class by Bev Skeggs as well as my own background, the article brings more specificity to the question of the working-class avant-garde and the Independent Group, using new research into the backgrounds of its members. Public funding enabled many who would not traditionally have benefitted from tertiary education to undertake full-time study, and this class dynamic made a difference to the post-war cultural landscape in the United Kingdom. The power of working-class agency within and against pre-existing elite structures is a key theme of the article. Working-class culture is a vital, yet hitherto marginalized, component of the Independent Group project. The article asks why references to social class are notably absent from accounts of post-war British art and design.
Beyond shared heritage: Unpacking the intersection of class and migration in the lives of Polish scholars in the United Kingdom and the United States
Authors: Luczaj Kamil
Published: December 2024

This article argues that class positions attained or inherited in one society cannot be easily transferred to another, and migration experience is inevitably linked to the process of re-classing. Drawing on Weiss’s analysis of social positions in the world society, Parreñas’s theory of ‘contradictory class mobility’ and Kelly’s fourfold definition of class, this article offers new insights into the impact of migration on scholars who moved from Poland – a semi-peripheral country, often considered a buffer zone between East and West – to the United States and United Kingdom. The empirical material, consisting of 36 biographically oriented in-depth interviews, suggests Polish scholars in the United Kingdom followed two main trajectories. The first trajectory (‘rollercoaster mobility’) involves educational migration, typical for middle- and upper-class individuals who plan their migration early in life. The second trajectory (‘uphill mobility’) encompasses the transition from a Polish secondary school or university student to a manual worker abroad, who eventually becomes an academic scholar.

Published: December 2024

Tanulmányunk a rovarok fogyasztói hasznosításának
aspektusait vizsgálja Európában, különös tekintettel a rovarokat
új élelmiszerként elfogadó négy fajra: közönséges lisztbogár,
keleti vándorsáska, házi tücsök és alombogár. Elemzésünk során
kiemelt figyelmet fordítunk ezek tápértékére, alacsony zsír- és
rosttartalmukra, valamint a hagyományos állattartáshoz képest
jelentős környezetvédelmi előnyeikre. Tanulmányunk rámutat, hogy
bár a rovarfogyasztás Európában viszonylag új, globálisan
elterjedt és elfogadott. A rovarok étkezési célú felhasználása
számos társadalmi és kulturális akadályt is felvet, melyek
leküzdése kulcsfontosságú a szélesebb körű elfogadás érdekében. Az
elfogadást támogató jogszabályi környezet kiemelten fontos,
beleértve az élelmiszerbiztonsági előírásokat és a megfelelő
címkézést.
