Influence factors on illuminance distribution uniformity and energy saving of the indoor illumination control method
Authors: Xiao Hua , Wang Zhanlang , Wang Guancheng
Published: February 2023

This study investigated the influence factors of illuminance
distribution uniformity and the energy-saving ability of the indoor
illumination control system, which consists of a white light-emitting
diodes (WLED) matrix and a tabletop matrix. In the proposed
illumination control method, comprehensive effects of time-invariant
and time-variant sunlight of the outdoor environment, arrangement of
the WLED matrix, iterative functions selected for illuminance
distribution optimization, and compositions of WLED optical spectra
are considered. The non-symmetrical spatial distribution of
WLED-tabletop matrices, the optical spectrum selection of WLEDs, and
the shifting sunlight intensity introduce obvious influence on (a)
emission intensity and distribution uniformity of the WLED matrix and
(b) receiving illuminance intensity and distribution uniformity of the
tabletop matrix. Additionally, the selection of iterative functions,
the WLED matrix dimension, the target error coefficient in the
iteration, and the optical spectra of the WLEDs cause non-negligible
influence on the energy saving percentage and iteration steps of the
proposed algorithm, influencing the effectiveness and accuracy of the
proposed method. Our investigation provides guidelines for the
improvement of optimization speed and accuracy of indoor illumination
control systems, and the method is hopefully to be widely applied in
manufacturing industry and intelligent office buildings.

Authors: Nishiyama Nobuhiko , Arai Shigehisa
Published: February 2023

Researches and developments of Si-photonics are hot topics in photonics field. This is because the technology has potentials to realize low-cost and compact products for various applications such as optical interconnection, sensing, LiDAR (Light Detection and Ranging)and so on. For passive components, most of components such as waveguides, splitters, combiners, filters, are being established. On the other hand, active components, especially semiconductor lasers, are still under developments since Si has indirect bandgap property and cannot achieve efficient emission. To overcome this problem, hybrid lasers, composed of III-V layer on top of Si or SOI substrates, were proposed and demonstrated. In this talk, I will review the progress of two types of hybrid lasers in our group, one is membrane lasers and the other is direct bonded hybrid lasers.

Published: February 2023

Terahertz (THz) photonics have been attracted much attention due to its remarkable progress [1]. Many LC devices in the visible to near-infrared range are driven using electric fields applied through transparent electrodes such as indium tin oxide (ITO) thin films. However, the inevitable absorption of ITO in THz region limits its application.[2] The alternative electrode for THz is still desired although several of approach such as nano-structure of reducing thickness of ITO have been proposed. In this work, Mg doped CuCrO2 films has been demonstrated its high transmittance in THz region. photonics. In addition, liquid crystal based terahertz (THz) phase shifter using CuCrO2:Mg as electrode was fabricated. Phase shift of around 2π at 1 THz was demonstrated. This is the first time to our best knowledge that CuCrO2:Mg can be used to fabricate THz phase shifter. The result reveal its potential for THz photonics.
Comparative Study on Temperature Sensors for Antenna-Coupled Bolometers: MOSFET, PN Junction Diode and Resistor
Authors: Elamaran Durgadevi , Satoh Hiroaki , Inokawa Hiroshi
Published: February 2023

Temperature sensor is the most important element in bolometers, and many kinds of sensors, such as resistor (thermistor), pn-junction diode, FET, etc., have been reported. However, there is a tradeoff between responsivity and output noise, and fair comparison has not been made among different devices and materials. This time, we systematically compare the performances of MOSFETs (n- and p-channel), pn-junction diodes (with and without body doping) and resistors with different materials (n+ and p+ single-crystal Si, and n+ polycrystalline Si) by assuming the 1-THz antenna-coupled bolometer that allows the area of 15 μm × 15 μm for the integrated heater and the temperature sensor.

Metalenses can achieve diffraction-limited focusing via localized phase modification of the incoming light beam. However, the current metalenses face to the restrictions on simultaneously achieving large diameter, large numerical aperture, broad working bandwidth and the structure manufacturability. Herein, we present a kind of metalenses composed of concentric nanorings that can address these restrictions using topology optimization approach. Compared to existing inverse design approaches, the computational cost of our optimization method is greatly reduced for large-size metalenses. With its design flexibility, the achieved metalens can work in the whole visible range with millimeter size and a numerical aperture of 0.8 without involving high-aspect ratio structures and large refractive index materials. Electron-beam resist PMMA with a low refractive index is directly used as the material of the metalens, enabling a much more simplified manufacturing process. Experimental results show that the imaging performance of the fabricated metalens has a resolution better than 600 nm corresponding to the measured FWHM of 745 nm.

Published: February 2023

Imaging through scattering layers based on the optical memory effect (OME) concept has been widely investigated in recent years. Among many scattering scenarios, it is very important to recover hidden targets with proper spatial distribution in the scene where multiple targets out of the OME range exist. In this Letter, we put forward a method for multi-target object scattering imaging. With the help of intensity correlation between the structured illumination patterns and recorded speckle images, the relative position of all hidden targets can be obtained and the movement of the targets within the OME range can be tracked. We experimentally implement scattering imaging with 16 targets and the motion tracking of them. Our results present a significant advance in a large field of view scattering imaging with multiple targets.
Optical realization of Rabi splitting in photonic integrated waveguide-coupled resonators
Authors: Moss David
Published: February 2023

Realizing optical analogues of quantum phenomena in atomic, molecular, or condensed matter physics has underpinned a range of photonic technologies. Rabi splitting is a quantum phenomenon induced by a strong interaction between two quantum states, and its optical analogues are of fundamental importance for the manipulation of light-matter interactions with wide applications in optoelectronics and nonlinear optics. Here, we propose and theoretically investigate purely optical analogues of Rabi splitting in integrated waveguide-coupled resonators formed by two Sagnac interferometers. By tailoring the coherent mode interference, the spectral response of the devices is engineered to achieve optical analogues of Rabi splitting with anti-crossing behavior in the resonances. Transitions between the Lorentzian, Fano, and Rabi splitting spectral lineshapes are achieved by simply changing the phase shift along the waveguide connecting the two Sagnac interferometers, revealing interesting physical insights about the evolution of different optical analogues of quantum phenomena. The impact of the device structural parameters is also analyzed to facilitate device design and optimization. These results suggest a new way for realizing optical analogues of Rabi splitting based on integrated waveguide-coupled resonators, paving the way for many potential applications that manipulate light-matter interactions in the strong coupling regime.
Bayesian inference of admixture graphs on Native American and Arctic populations
Authors: Nielsen Svend V. , Vaughn Andrew H. , Leppälä Kalle , Landis Michael J. , Mailund Thomas , Nielsen Rasmus
Published: February 2023

Admixture graphs are mathematical structures that describe the ancestry of populations in terms of divergence and merging (admixing) of ancestral populations as a graph. An admixture graph consists of a graph topology, branch lengths, and admixture proportions. The branch lengths and admixture proportions can be estimated using numerous numerical optimization methods, but inferring the topology involves a combinatorial search for which no polynomial algorithm is known. In this paper, we present a reversible jump MCMC algorithm for sampling high-probability admixture graphs and show that this approach works well both as a heuristic search for a single best-fitting graph and for summarizing shared features extracted from posterior samples of graphs. We apply the method to 11 Native American and Siberian populations and exploit the shared structure of high-probability graphs to characterize the relationship between Saqqaq, Inuit, Koryaks, and Athabascans. Our analyses show that the Saqqaq is not a good proxy for the previously identified gene flow from Arctic people into the Na-Dene speaking Athabascans.
Biosynthetic constraints on amino acid synthesis at the base of the food chain may determine their use in higher-order consumer genomes

Published: February 2023

Dietary nutrient composition is essential for shaping important fitness traits and behaviours. Many organisms are protein limited, and for Drosophila melanogaster this limitation manifests at the level of the single most limiting essential Amino Acid (AA) in the diet. The identity of this AA and its effects on female fecundity is readily predictable by a procedure called exome matching in which the sum of AAs encoded by a consumer’s exome is used to predict the relative proportion of AAs required in its diet. However, the exome matching calculation does not weight AA contributions to the overall profile by protein size or expression. Here, we update the exome matching calculation to include these weightings. Surprisingly, although nearly half of the transcriptome is differentially expressed when comparing male and female flies, we found that creating transcriptome-weighted exome matched diets for each sex did not enhance their fecundity over that supported by exome matching alone. These data indicate that while organisms may require different amounts of dietary protein across conditions, the relative proportion of the constituent AAs remains constant. Interestingly, we also found that exome matched AA profiles are generally conserved across taxa and that the composition of these profiles might be explained by energetic and elemental limitations on microbial AA synthesis. Thus, it appears that ecological constraints amongst autotrophs shape the relative proportion of AAs that are available across trophic levels and that this constrains biomass composition.
Evaluating situational judgment test use and diversity in admissions at a southern US medical school
Authors: Gustafson Chelsea E. , Johnson Crystal J. , Beck Dallaghan Gary L. , Knight O’Rese J. , Malloy Kimberly M. , Nichols Kimberley R. , Rahangdale Lisa
Published: February 2023

Introduction

Situational judgment tests have been adopted by medical schools to assess decision-making and ethical characteristics of applicants. These tests are hypothesized to positively affect diversity in admissions by serving as a noncognitive metric of evaluation. The purpose of this study was to evaluate the performance of the Computer-based Assessment for Sampling Personal Characteristics (CASPer) scores in relation to admissions interview evaluations.

Methods

This was a cohort study of applicants interviewing at a public school of medicine in the southeastern United States in 2018 and 2019. Applicants took the CASPer test prior to their interview day. In-person interviews consisted of a traditional interview and multiple-mini-interview (MMI) stations. Between subjects, analyses were used to compare scores from traditional interviews, MMIs, and CASPer across race, ethnicity, and gender.

Results

1,237 applicants were interviewed (2018: n = 608; 2019: n = 629). Fifty-seven percent identified as female. Self-identified race/ethnicity included 758 White, 118 Black or African-American, 296 Asian, 20 Native American or Alaskan Native, 1 Native Hawaiian or Other Pacific Islander, and 44 No response; 87 applicants identified as Hispanic. Black or African-American, Native American or Alaskan Native, and Hispanic applicants had significantly lower CASPer scores than other applicants. Statistically significant differences in CASPer percentiles were identified for gender and race; however, between subjects, comparisons were not significant.

Conclusions

The CASPer test showed disparate scores across racial and ethnic groups in this cohort study and may not contribute to minimizing bias in medical school admissions.
Parental gambling frequency and adolescent gambling: A cross-sectional path model involving adolescents and parents
Authors: Donati Maria Anna , Beccari Carola , Sanson Francesco , Iraci Sareri Giuseppe , Primi Caterina
Published: February 2023

Introduction

Nowadays, most of the research studies in the field of adolescent gambling are focused on individual factors related to problem gambling. The aim of this study was to test an integrated model to explain adolescent problem gambling involving both individual (i.e., correct gambling knowledge, superstitious thinking, and gambling-related cognitive distortions) and environmental factors (i.e., parental gambling frequency). In detail, the aim was to better understand the role of parental gambling behavior on adolescents’ gambling frequency and problem gambling severity, to draw indications for prevention.

Methods

Participants were 680 parents (36% men; Mage = 48.32, SD = 6.14 years) of 680 high school students (51% boys; Mage = 15.51, SD = .55 years) attending the second year of different high schools in Tuscany (Italy). Data collection occurred within the school prevention program PRIZE (Prevention of gambling risk among adolescents).

Results

A path model showed was conducted to detect direct and indirect effects from individual and environmental factors to gambling problem severity. Analyses showed that correct gambling knowledge and superstitious thinking were directly related–respectively in a negative and a positive direction–both to gambling-related cognitive distortions and adolescents’ gambling frequency. Parental gambling frequency was directly associated with adolescents’ gambling frequency. Correct gambling knowledge and superstitious thinking were indirectly related to adolescents’ gambling problem severity through the mediational role of gambling-related cognitive distortions and gambling frequency. Parental gambling frequency was indirectly linked to gambling problem severity by passing through adolescents’ gambling frequency.

Conclusions

The current cross-sectional results confirm that parental gambling behavior has an important role for adolescents’ gambling behavior and severity. Thus, results highlight the need for innovative prevention programs which involve adolescents’ adult reference figures and integrate the individual risk and protective factors with the environmental ones.
Higher Dose Oral Fluconazole for the Treatment of AIDS-related Cryptococcal Meningitis (HIFLAC)—report of A5225, a multicentre, phase I/II, two-stage, dose-finding, safety, tolerability and efficacy randomised, amphotericin B-controlled trial of the AIDS Clinical Trials Group

Background

The WHO recommended 1200mg/day of fluconazole (FCZ) in the induction phase of cryptococcal meningitis (CM) in HIV prior to 2018 in regions where amphotericin-B (AMB) was unavailable. A 2-stage AMB-controlled, dose-escalation study to determine the maximum tolerated dose and the safety/efficacy of an induction-consolidation strategy of higher doses FCZ (1200mg-2000mg/day), adjusted for weight and renal function (eGFR)in adults with CM was undertaken.

Methods

In Stage-1, three induction doses of FCZ (1200mg/day, 1600mg/day and 2000mg/day) were tested in sequential cohortsand compared with AMB in a 3:1 ratio. A particular dose was not tested in Stage 2 if there were significant predetermined safety or efficacy concerns. In Stage-2, the 1200mg dose was excluded per protocol because of increased mortality, and participants were randomised to 1600mg, 2000mg FCZ or AMB in a 1:1:1 ratio.

Findings

One hundred and sixty eight participants were enrolled with 48, 50, and 48 in the AMB, 1600mg and 2000mg cohorts. The Kaplan Meier proportion for mortality (90% CI) at 10 and 24 weeks for AMB was 17% (10, 29) and 24% (15, 37), compared to 20% (12, 32) and 30% (20, 43) for 1600mg, and 33% (23, 46) and 38% (27, 51) for 2000mg/day FCZ. With the exception of a higher incidence of gastrointestinal side effects in the 2000mg cohort, both induction doses of FCZ were safe and well tolerated. There were no life-threatening changes in electrocardiogram QTc which were similar across all doses of FCZ and AMB. The median (IQR) change in log10 cryptoccal colony forming units (CFU) from week 0 to week 2 was -8(-4.1,-1.9) for AMB; -2.5(-4.0, -1.4) for 1600mg FCZ and -8 (-3.2, -1.0) for 2000mg FCZ. The proportion (90% CI) CSF CM negative at 10 weeks was 81%(71,90) for AMB; 56%(45,69) for 1600mg FCZ and 60%(49,73) for 2000mg FCZ.

Interpretation

Induction phase weight and renal-adjusted doses of 1600mg and 2000mg/day FCZ for CM were safe and well tolerated except for increased GI side effects in the 2000mg/day dose, and had similar times to achieve CSF sterilization, but took significantly longer than AMB. The WHO recommended 1200mg FCZ was associated with a high mortality. While not statistically significant, mortality was numerically lower in the AMB compared to 1600mg and 2000mg FCZ These data make a case for a phase 3 study of higher doses of FZC.
Inaugurating discussions of an oral cinema: Placing the translation-to-screen of Scottish community oral storytelling traditions within a wider frame of global filmmaking practice
Authors: Chambers Jamie
Published: February 2023

This article seeks to inaugurate the global frame of an oral cinema: a cinema that, to a significant extent, is defined by its relationship to community oral cultures. Whilst the case studies featured are largely those arising from Scotland – in particular Simon Miller’s Seachd: The Inaccessible Pinnacle (), Timothy Neat’s Play Me Something () and the author’s own film Mysterious Object (currently in post-production) – discussion deliberately reaches outwards to a global, comparative frame drawing upon the more sophisticated treatments of orality in the West African cinemas of Gaston Kaboré and Ousmane Sembene and the Inuit cinema of Zacharius Kunuk. Whilst alive to the dangers of homogenization and destructive, western-led universalisms, this article ultimately attempts to establish a space for utopian montage (), wherein divergent yet mutually resonant traditions within world cinema may be co-positioned in order to explore aspects of shared practice and solidarity.
Burning questions and multiple answers: Ambiguous-unreliable narration and the uncertainties of truth and trust
Authors: van der Wal Hilde , Medina Marañón Nicolás , Willemsen Steven
Published: February 2023

This article explores how ambiguous-unreliable narration occurs in cinema as a distinct mode of unreliability. In defining ambiguous narration, we build on Semir Zeki’s neurobiological notion of ambiguity, from which we understand ambiguous narration as a mode that presents a series of questions consistently answered in mutually contradictory ways. We pay specific attention to Robert Vogt’s definition of ambiguous-unreliable narration in order to get a grip on the possible storyworlds presented by Lee Chang-dong’s 2018 feature film Burning. The film cues viewers to consider multiple interpretations of diegetic truth, each interpretation tapping into another possible world of events by positing questions with multiple non-hierarchable answers. As such, it becomes clear how Burning plays upon different concepts of ‘truth’. Drawing on the work of Vittorio Bufacchi and Kevin Reuter and Georg Brun, we can see how Burning ambiguates the line between correspondentist and coherentist readings of truth, thereby revealing something significant about truth-assigning strategies. We argue that Burning mimetically evokes post-truth phenomena, a periodizing concept in which the differentiation between fact-based truths, opinions and lies is blurry, creating an ambiguous information environment characterized by an uncertainty of what one can consider (un)trustworthy or (un)reliable. By proposing a cognitive narratological approach, we demonstrate how film storytelling can mimetically evoke this experience of uncertainty. In light of these findings, this research addresses the educative value of ambiguous-unreliable narration within fiction, especially within curricular programmes that incorporate media literacy training.
Rites of passage in the cinema of Yasujiro Ozu
Authors: Martins Hugo
Published: February 2023

Yasujiro Ozu develops the narrative of his films around transitory rites in the lives of the characters. For Ozu, the family is the core of sustenance of the home and it is its stability that is called into question. The present article intends to relate, due to the proximity to the everyday and community life of Ozu’s characters, the threats to the stability of the family home with the rites of passage identified by the French ethnologist Arnold van Gennep. Van Gennep defines rites of passage as the ceremonies that accompany an individual’s life crises. And also, especially in the films around the daughters’ marriages, to the state of liminality or margin developed by the Scottish anthropologist Victor Turner. In these, the main conflict is centred on the character’s struggle to change, because of a ritual that is not accomplished or that will, in the face of society and the values of an epoch, be belatedly fulfilled. It is the tension between modernity and tradition that places the characters in a liminal state, giving rise to a sense of slow separation, of non-status and of late. In these films (Late Spring, Early Summer, Late Autumn, An Autumn Afternoon) Ozu illustrates an avowed desire to portray the cycle of life or mutability rather than the action itself.

«Honrar a nuestros héroes muertos». Conmemoraciones públicas, monumentos y memoria de las guerras carlistas
Authors: Martín Etxebarria Gorka
Published: February 2023

La entrada de Europa en la Contemporaneidad estuvo marcada por conflictos, tanto internacionales como internos. Las contradicciones causadas por la Modernidad fueron solventadas, más de una vez, en el campo de batalla. En el contexto del convulso siglo XIX español las guerras carlistas representaron la pugna entre aquellos que querían continuar implantando la revolución liberal burguesa, por un lado, y quienes defendían el mantenimiento de los privilegios heredados del Antiguo Régimen, por el otro lado. El conflicto vehiculó buena parte del siglo y estalló en guerra civil abierta en tres ocasiones. A la finalización de la última de ellas en 1876 le siguió una nueva lucha en esta ocasión por la apropiación del relato de las mismas. En este sentido, ambos bandos implementaron una agencia de conmemoración que buscaba crear una memoria propia sobre el conflicto. Para ello se emplearon diferentes recursos como publicaciones periódicas en prensa, obras bibliográficas de marcado sesgo político, cambios en la nomenclatura del callejero urbano o conmemoraciones anuales. No obstante, la erección de monumentos conmemorativos, por sus rasgos, objetivos y significación, adquirió una importancia capital como herramienta mnemónica en la creación y renovación de dichos relatos. Su materialización en un espacio público y compartido, junto a la instauración de un marcado ritual, hicieron de ellos verdaderos lugares de memoria. En este artículo se explora la intrahistoria de varios monumentos carlistas y liberales poniendo especial atención en sus características, rituales, momentos de construcción, evolución posterior y estado actual. De esta manera reconstruimos el proceso por el cual estos monumentos se convirtieron en lugares de memoria y lo que representaron para la sociedad del momento. De la misma forma, ponemos atención a su declive y estado actual para observar cómo y por qué fueron destruidos, resignificados y/o abandonados. Concluimos con una serie de reflexiones sobre memoria, patrimonio, monumentos y poderes estatales.
La prensa carlista en el exilio: La Voz de la Patria y la internacional blanca
Authors: Dupont Alexandre
Published: February 2023

En las dos guerras de 1833-1840 y 1872-1876, los carlistas fundaron, gracias al apoyo de exiliados instalados en el país, periódicos en Francia a través de los cuales pretendían tanto eludir la censura y la represión en su país como dirigirse a la opinión pública europea y más precisamente a sus partidarios contrarrevolucionarios más allá de las fronteras. La Voz de la Patria, creado en Bayona en 1874 por Carlos Benítez Caballero es buena muestra de esta prensa carlista en el exilio y de su papel fundamental en la conformación de una internacional blanca pro-carlista, tanto por las mismas condiciones de elaboración del periódico como por el ideario propagado por este título bilingüe. De hecho, los promotores de esta empresa no se limitaron en crear un periódico dirigido hacia los propios refugiados carlistas en Francia y destinado a hacer de vínculo entre ellos. Bien al contrario, hicieron de La Voz de la Patria un laboratorio y una caja de resonancia de la solidaridad pro-carlista que se organizó en Francia y en toda Europa durante la guerra de 1872-1876 y se dirigieron tanto a los carlistas como a los monárquicos y católicos de Europa –en especial franceses. La represión que padeció el periódico y el proceso que derivó en 1875 subrayan las angustias márgenes de maniobra del Estado francés para luchar contra un instrumento de subversión contrarrevolucionaria que usaba los códigos del espacio público liberal y pone de relieve la paradójica modernidad de los carlistas y de sus aliados que supieron adaptar los instrumentos de la política liberal para usarlos en su propio combate.
El poder y las armas contra biberones y pañales. La denuncia por los «niños desaparecidos» y su conformación como problema público durante la última dictadura en Argentina (1976-1983)
Authors: Laino Sanchis Fabricio Andrés
Published: February 2023

La apropiación criminal de niños y niñas en el marco del plan sistemático de desaparición de personas fue una de las características de la represión estatal en Argentina durante la década de 1970, especialmente después del golpe de Estado realizado por las Fuerzas Armadas el 24 de marzo de 1976. Tras el final del régimen militar, este crimen y la lucha de los familiares, especialmente de la organización Abuelas de Plaza de Mayo, por encontrar a esas personas apropiadas ha concitado una considerable atención social y política. Ahora bien, aunque este delito se produjo desde los inicios del terrorismo de Estado, en 1975, su caracterización como una dimensión específica y sistemática de la represión y su incorporación como un reclamo particular dentro de la agenda de reclamos de los familiares y organismos de derechos humanos se produjo de forma más tardía y gradual. Cabe preguntarse, entonces, cuándo y cómo se produjo esta transformación. ¿Quiénes y cómo comenzaron a reclamar por estos niños y niñas que «desaparecían» junto con sus padres y madres? ¿En qué momento se consolidó como una denuncia específica del movimiento de derechos humanos? En este artículo indagaremos en estas preguntas para ver de qué manera se conformó una demanda puntual dentro del movimiento de derechos humanos en torno al reclamo por los «niños desaparecidos», que llegó a convertirse, hacia los años finales de la dictadura, en un problema público a nivel nacional e, incluso internacional. Para abordar estos interrogantes, hemos relevado y analizado, en archivos de Argentina y otros países, diferentes fuentes escritas: prensa argentina y extranjera, publicaciones de Abuelas de Plaza de Mayo y de otros organismos de derechos humanos, denuncias internacionales e informes sobre violaciones a los derechos humanos en Argentina, entre otras. En nuestro análisis, observaremos el papel jugado por los testimonios de los/as sobrevivientes de los centros clandestinos de detención y de una incipiente organización de «madres-abuelas» en la instalación de este reclamo específico dentro de la agenda del movimiento de derechos humanos, las modulaciones discursivas que adquirió su denuncia, sus repercusiones y la capacidad para instalarlo progresivamente como un problema en la discusión pública en Argentina y, hasta cierto punto, también en el exterior.
El «Sindicato» y la captura de Francia. Le Triboulet y la percepción del «Estado profundo» en el espacio antiliberal (1880-1907)
Authors: Pubill Brugués Joan
Published: February 2023

A través de la figura del «Sindicato» concebida por el semanario orleanista Le Triboulet, el objetivo de este trabajo es reflexionar sobre la percepción que tuvieron los sectores antiliberales respecto a la existencia de un «Estado profundo» que controlaría el devenir de Francia para sus intereses. En este sentido, el trabajo pretende repensar el mito del «complot judeo-masón», propagado con fuerza en el período histórico que abarcó los mayores escándalos políticos de la Tercera República, más allá de la retórica paranoide o xenófoba. También se propone comprenderlo como la codificación del disfuncionamiento entre cuerpo nacional y cuerpo político que derivó de unas impresiones sesgadas sobre las transformaciones profundas acaecidas durante la modernidad. Los avatares de «judío» y de «masón» se convertirían, de este modo, en categorías antimodernas que encapsulan el odio hacia quienes se consideraban los dos pilares de los regímenes liberal-parlamentarios: el «dinero» y el «secreto».

«Por una política revolucionaria en el frente de la enseñanza». La crítica de Manuel Sacristán tras 1968 a través de su práctica política en la universidad
Authors: Sancho Galán Jordi
Published: February 2023

En este estudio nos aproximamos a la visión crítica expresada por Manuel Sacristán tras 1968, tanto del movimiento comunista internacional como de la línea política seguida por el PSUC. Los sucesos acaecidos ese año, entre los que destacan el Mayo Francés y la invasión soviética de Checoslovaquia, conmocionaron a los partidos comunistas occidentales y a sus militantes, lo que para Sacristán se traducirá en una profunda y pesimista crítica que lo llevará, en 1969, a su dimisión de los órganos de dirección del PSUC. Manuel Sacristán había sido desde su llegada a la Universidad de Barcelona, en 1956, un referente para los estudiantes opositores al franquismo, por ello se le encargó la redacción del manifiesto fundacional del Sindicato Democrático de Estudiantes, y también para los sectores intelectuales y profesionales comunistas. No es exagerado considerarlo el principal filósofo del marxismo en la España del momento, manteniendo al mismo tiempo una constante práctica militante. Pero a pesar de su envergadura política e intelectual, sus reflexiones han sido hasta tiempos muy recientes poco estudiadas y especialmente descuidadas académicamente. Hay en ello dos motivos esenciales, de una parte, su propia heterodoxia y, por otra, que su discrepancia fue expresada en el momento internamente dejando poca documentación pública y, por lo tanto, son escasas las posibilidades que tenemos de conocerla en los mismos términos en los que en ese momento se produjo. Es por ello por lo que la reconstruimos a partir de la documentación interna del partido, centrada en diversos debates entre Sacristán y la dirección que tienen como foco principal el movimiento universitario, pero que trascienden a este y nos aportan elementos clave para entender su visión del movimiento comunista tras 1968 en su dimensión más global.

Współczesne działania na rzecz jej dobra zwykle opierają się na koncepcji empowermentu, czyli umacniania – dążąc do autonomizacji rodziny, starając się odbudować więź między rodzicami a dziećmi. W zasadzie większość tych rozwiązań było obecnych w przedstawionej w II połowie XX wieku koncepcji pracy z rodziną zagrożoną autorstwa Marii Łopatkowej. Celem niniejszego artykułu jest przypomnienie tej koncepcji i wskazanie jej aktualności.
Between e-culture and real culture: a peep through the lenses of Nollywood
Authors: Abakporo Princewill , Samuel Gloria
Published: February 2023

E-culture otherwise referred to as electronic culture has become a robust field of study especially in understanding its trajectories and intersections with politics, economy, propaganda, education, culture, and arts. The term which generally captures everything that can be classified as online or digital culture has become a dominant factor in (re)imaging, projecting, and influencing opinions about individuals, ideologies, policies, culture, and arts. It has also fueled debates about fidelity between what is projected online and the reality of the situation offline especially as seen in Nollywood films. This work pilfers from the canons of Cultivation and Spiral of Silence theories, to investigate the fidelity of Nollywood as e-culture to Igbo culture and the consequent transnational impressions created by the medium about the Igbo character and his cultural allegiances. Through assessment of Igbo cultural motifs in domains of costume, makeup, and Igbo character portrayals in recently selected films, this work fingers Nol- lywood as responsible for the demeaned diasporic perceptions about Nigeria as well as the persistent Igbo cultural erosions. It concludes that while we give credit to Nollywood in areas of thematic render- ing of the Nigerian realities, the Igbo contextual (Igbo periodic and geographic settings) presentation is what this paper classes as pseudo-culture, a culture that betrays its source or what Ernest-Samuel Glo- ria refers to as “imitation of imitation.” It recommends among others, the privileging of a re-engineered mindset of filmmakers and cultural research in Igbo films to redeem the Igbo identity and possibly avert the UNESCO prediction of erosion of salient aspects of Igbo Culture by 2025.

The increase in breast cancer survivors (BCS) has established unprecedented demands on health systems worldwide. In this context, new knowledge is needed to subsidize strategies to handle this population. The objective of this study was to combine the correlations between anthropometric, hematological, biochemical, biophysicochemical, muscle strength, and age variables in BCS. Twenty-two volunteers (51.7 ± 9.2 years old) with a history of mastectomy and lymphadenectomy participated in the study. Among the results, the correlations of the body mass index with lipid profile, strength, and body composition draw special attention. The associations of lipid profile with erythrocyte membrane stability, body composition, and leukocyte count, the associations of the red cell distribution width (RDW) with body mass index, lipid profile, and strength, and the positive correlation between age and leukocyte count also deserve highlights. Such findings allow concluding that investigations that deal singly with health indicators represent a severe limitation in the study of the public in question, and it is necessary to avoid them. The complex network of interactions observed between the various parameters studied reinforces the importance of a global biological analysis of attractive cost-benefit and great practical potential. Teams with medical, nutrition, physical therapy, and physical education professionals, among other areas, can use this knowledge to improve BCS's interdisciplinary approaches in short, medium, and long-term management.
Refractory hypokalemia with sexual dysplasia and infertility caused by 17α-hydroxylase deficiency and triple X syndrome: A case report

Published: February 2023

The present study reports a patient case with a 17α-hydroxylase deficiency accompanied by triple X syndrome. A 17α-hydroxylase deficiency leads to a very low 17α-hydroxylated steroid synthesis as well as a non-feedback increase in the adrenocorticotropic hormone level. Meanwhile, the progesterone level increases the 17α-hydroxyprogesterone level and decreases the dehydroepiandrosterone sulfate level. The patient is characterized by intractable hypokalemia, high urinary potassium, hyperaldosteronemia, hyporeninemia, hypocortisolemia, hypertension, gonadal and secondary sexual dysplasia, a decreased estrogen level, primary amenorrhea, and infertility. The imaging findings indicate a presence of multiple bilateral adrenal gland adenomas, and the sequencing indicates a missense CYP17A1-E7 gene pathogenic variant. The karyotype is a 47, XXX [3]/46, XX [47] low-level chimeric karyotype. The patient’s parents are cousins. To our knowledge, this patient is the first case diagnosed with congenital adrenal hyperplasia caused by hydroxylase deficiency and triple X syndrome. The uniqueness of this case is that this patient has two very rare genetic diseases, probably due to the marriage of close relatives.

Objectives

Clinical laboratory results are required for critical medical decisions, underscoring the importance of quality results. As part of total quality management, external quality assessment (EQA) is a vital component to ensure laboratory accuracy. The goal of this survey was to evaluate the current status of global laboratory quality systems and assess the need for implementation, expansion, or harmonization of EQA programs (EQAP) for Clinical Chemistry and Laboratory Medicine.

Methods

The International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Task Force on Global Laboratory Quality (TF-GLQ) conducted a survey of IFCC full and affiliate members (n=110) on laboratory quality practice. A total of 41 (37.3%) countries representing all IFCC regions except North America provided responses about EQA availability and practices.

Results

All 41 countries perform EQA, 38 reported that their laboratories had EQA policies and procedures, and 39 further act/evaluate unacceptable EQA results. 39 countries indicated they have international and/or national EQAP and 30 use alternative performance assessments. EQA frequency varied among countries. Generally, an EQAP provided the EQA materials (40/41) with four countries indicating that they did not have an EQAP in their country.

Conclusions

Globally, most laboratories participate in an EQAP and have defined quality procedures for EQA. There remain gaps in EQA material availability and implementation of EQA as a part of a total laboratory quality system. This survey highlights the need for education, training, and harmonization and will guide efforts of the IFCC TF-GLQ in identifying areas for enhancing global laboratory quality practices.
Effect of the interaction between wood constituents and swelling liquid on the creep properties of wood during drying
Authors: Miyoshi Yuka , Furuta Yuzo
Published: February 2023

This study aimed to clarify the effect of the interactions between the swelling liquid and wood constituents on the creep behavior during drying. Creep tests were conducted during drying of four sample groups (untreated, acetylated, delignified, and hemicellulose-extracted samples) that were swollen using water, one organic liquid, or water-organic mixtures. The largest creep deformation was measured for the hemicellulose-extracted samples, followed by delignified, untreated, and acetylated samples. Apart from the acetylated samples, all treated samples tended to have large creep deformation in water-organic mixtures. For the acetylated samples, the creep deformation was small, except in case of acetone. These differences in the creep deformation behavior are mainly due to the differences in the glass-transition temperature of lignin as a result of the interaction between the wood constituents and the swelling liquid. The considerable increase in creep deformation due to hemicellulose-extraction suggests that hemicellulose, which interacts with lignin and cellulose, reduces the fluidity of the wood due to liquid desorption during creep measurements.
COVID-19 and processes of adjustment in people with persistent pain: the role of psychological flexibility
Authors: McCracken Lance M. , Buhrman Monica , Brocki Karin
Published: February 2023

Objectives

The purpose of the current study was to investigate facets of Psychological Flexibility (PF) and Psychological Inflexibility (PI) and their relations with depression, anxiety, and insomnia in people with chronic pain during the COVID-19 pandemic. It was predicted that the full set of facets would significantly predict all three outcomes. The relative contributions of differing facets and dimensions was explored.

Methods

Participants with pain were selected from a sample of 1,657 Swedish adults responding to an online survey of health and COVID-19. Persistent pain was defined as pain on most days, present for three months or more. A total of 560, 33.8% of the total sample, were included in the analyses. Standardized and validated measures were used to measure depression, anxiety, and insomnia, and the Multidimensional Psychological Flexibility Inventory (MPFI) was used to measure both PF and PI.

Results

Significant rates of depression, anxiety, and insomnia, at 43.1, 26.4, and 64.2%, respectively, were found in this sample. These rates appear higher than those found in a general sample in Sweden. PF was negatively associated with these problems while PI was positively associated with them. Better prediction of outcome was obtained by PI compared to PF.

Conclusions

PF and especially PI appear to have played a role in relation to health outcomes in people with persistent pain during the COVID-19 pandemic. This group of people appears to have been especially vulnerable to the impacts of the pandemic. This study motivates further investigation and development of treatment approaches, possibly focusing on training PF, for people with persistent pain in the current pandemic context and in the future.
Orthoamide und Iminiumsalze, CVIII. Umsetzungen von Orthoamiden der Alkincarbonsäuren mit CH/NH-aciden, tautomeriefähigen Verbindungen

The reaction of keten-O,N-acetals, which can exist in tautomeric forms, with orthoamides of alkine carboxylic acids 4 affords pyridine carboxylic acid esters or -nitriles. Analogous reactions of the orthoamides 4 with imidazole-2-yliden-acetic acid ester or -acetonitrile deliver imidazo[1,2-a]pyridines. From N-alkyl-3,3-diamino-acrylic acid derivatives and orthoamides of propiolic acid 4-aza-heptatriencarbonitriles can be prepared, whereas orthoamides of phenylpropiolic acid deliver directly 2H-pyrimidine-2-ylidene-cyanacetic acid derivatives. 4-Amino-cumarine reacts with orthoamides 4 to give isomeric 5-oxo-[1]-benzopyrano[4,3-b]pyridines. The orthoamides 4 transform 1,3-diimino-isoindolin into 2-cyanphenylpyrimidines. 2-(Pyrazol-1-yl)-benzamides can be prepared from 3-indazolinon and orthoamides 4. The reaction of orthoamides 4 with 6-amino-1,3-dimethyl-uracil proceeds in a complex manner and gives primary products which are very likely imidazo-diazepines. By thermolysis of one of these products a fluorescent pyrolo-imidazolidindione is obtained, which was alkylated with triethyloxonium tetrafluoroborate to give a quaternary ammonium tetrafluoroborate.
