Social care in childhood and adult outcomes: double whammy for minority children?
Authors: Sacker Amanda , Murray Emily T. , Maughan Barbara , Lacey Rebecca E.
Published: December 2023

Background

Children in social care report poor outcomes in many aspects of their later lives. Less is known about differences by ethnicity.

Objective

We examined the health, socio-economic, family and living arrangements across the first three decades of adult life by the intersection of ethnicity (White, Black, South Asian) with social care.

Participants and setting

Linked census and life events data for a 1% sample of the population of England and Wales in the ONS Longitudinal Study. Participants were dependent children in 1971–2001 (analytic sample n = 669,474).

Methods

Categorical regression models compared health, socio-economic circumstances, living arrangements and relationships, controlling for country of birth, childhood census year, childhood and adult age in years, gender, and head of household social class, qualifications, employment status and marital status.

Results

Adverse adult outcomes following social care in childhood were conditional on the interaction of social care with ethnicity, mainly in the socio-economic domain. For some outcomes the White group had the poorest outcomes: for example, 15% lower probability of being employed than other White people (65% versus 80%). Black adults with a history of social care did not differ from other Black adults, except for the lowest probability of acquiring their own home, while care-experienced South Asian adults did not differ from other South Asian adults.

Conclusion

Minority ethnicity moderated the social care to adult outcomes relationship in both positive and negative ways. Overall, there was little evidence of intersectionality for Black children in social care affecting their life chances.
Grammars of Progress and Pathology: A Recursive History of Africa, Cancer, and "Diseases of Civilization"
Authors: Cochrane Thandeka , Reubi David
Published: December 2023

summary: The phrase "disease of civilization" and concomitant lexicons, such as "pathologies of modernization," frequently surface across public and global health discourses. This is particularly the case within the framework of cancer research in Africa. In this article, the authors trace the emergence of these grammars of progress at the beginning of the twentieth century as a biomedical lens through which to analyze and frame cancer in Africa. Arguing with Ann Stoler for a recursive understanding of colonial and postcolonial history, the authors follow in detail the lexical shifts and recursions across the twentieth century, as these grammars move from diseases of civilization to development and modernization. In tracing these lexical shifts, they place them within the broader understandings of Africa and the African body as an other against which Euro-America frames itself.
Precarious Freedoms: Intergenerational Divisions within the Black Family in Postcolonial Córdoba, Argentina
Authors: Edwards Erika Denise
Published: December 2023

Abstract: This article explores the intergenerational dynamics within the Black family in postcolonial Córdoba, Argentina. It delves into the difficult reality that Black emancipation did not define freedom. Instead "free" status remained a precarious existence to which some free and free(d) Black parents clung by differentiating themselves from the enslaved population. Through the examination of marriage dissent court cases that featured African-descended families as plaintiffs and defendants, this article demonstrates that the maintenance of a social hierarchy that discriminated against the enslaved did not only emanate from external influences, such as governing authorities and policies, but the African-descendant population also internalized and upheld it.
"I had resolved that I would be virtuous, though I was a slave": Enslaved Women, Feminine Virtue and the Sexual Economy of US Slavery
Authors: Esty Kaisha
Published: December 2023

Abstract: This article traces the powerful currency of notions of feminine virtue among enslaved women in the antebellum US South. Early nineteenth-century white American ideas of "female virtue" were limited to white womanhood and legitimized US white supremacist and patriarchal imperialism. Exploited for their reproductive and productive labor, enslaved women were denied the assumption of feminine virtue. Rather, they were positioned at the center of slavery's sexual economy. Yet, enslaved women developed a transnational and multifaceted understanding of feminine virtue that they enlisted and passed on to their daughters as a form of subversion. This article argues that enslaved women's concerns with and actions around virtue reveals a strategy through which they struggled for sexual autonomy.
The Upper Nicola Nsyilxcn Talking Dictionary Project: Community-Driven Revitalization Lexicography within an Academic Context
Authors: Lyon John , Manuel ḱᵂaḱᵂíslaɁqn Justine , Michel xᵂəstalqs Kathleen
Published: December 2023

ABSTRACT: The Upper Nicola dialect of Nsyilxcn (aka Okaangan Salish) currently has fewer than twelve first-language speakers ( twi -Sharon Lindley, p.c.). This paper describes the Upper Nicola Nsyilxcn Talking Dictionary Project, a community-driven, collaborative project that utilizes heritage language recordings and their associated transcriptions with the goal of developing an online dictionary resource for use by the Upper Nicola Syilx community. The content of the dictionary stems from recently digitized recordings (originally made by Dr. Yvonne Hébert between 1978 and 1980) of elder twi -Joseph Albert Michel reciting Nsyilxcn words and sentences along with their English translations. The collection now consists of 6,831 individual sound files, which our team is currently transcribing with the aid of published language materials. A significant number of lexical items are either unique to this dialect, or otherwise previously undocumented. Our team currently consists of a linguist and two Syilx Indigenous language learners from the Upper Nicola who are enrolled in University of British Columbia, Okanagan's Bachelor of Nsyilxcn Language Fluency Program. This project is important since there has never before been any published dictionary of the Upper Nicola dialect. This project also builds capacity within the community for language maintenance and provides a model for future collaborations between Indigenous communities and academic institutions.
An Open-Access Toolkit for Collaborative, Community-Informed Dictionaries
Authors: Trotter Bailey , Schreyer Christine , Turin Mark
Published: December 2023

ABSTRACT: In this article, we discuss the development of a relational lexicography framework and an open-access toolkit for collaborative, community-informed dictionaries. We explain how the relational lexicography toolkit supports envisioning, developing, and publishing dictionaries that meet the cultural, linguistic, and educational goals of Indigenous communities who, despite ongoing language shift, are working to strengthen their languages. This framework recognizes the many relationships that are present in community-based language projects, including relationships between speakers, dialects, academics, communities, and the dictionary itself. The toolkit, which comprises two online Knowledgebase of Indigenous language dictionaries and lexicography technologies, documents how these relationships have been represented in existing work and provides a centralized platform to refer to and compare resources. Overall, this article provides background context on our methodology, project development, aspects of the resulting resources, and the anticipated benefit of creating such an open-access framework in support of community-based lexicography.
Gorgias's Encomium to Helen as an Existential and Protreptic Logos: Self-reflexivity, Temporality, and the Four Causes
Authors: Rickert Thomas J.
Published: December 2023

Abstract: Gorgias's Encomium of Helen stands out as more than a display speech: it is a sophisticated statement on fifth century Greek life. Within a mythic framework, it presents Gorgias's post-Eleatic understanding of the world, including new ways of conceiving the logos within the finite boundaries of human life. I show how Gorgias's thoughts build out of Empedocles's cosmology and stylistics, leading Gorgias to consider more deeply how language and world go together. I demonstrate that the order of Gorgias's four causes is cyclical, which allows Gorgias to make gradated distinctions about responsibility. Gorgias's exploration of responsibility enables him to portray the world as something that continually marks and molds human being, and this includes the logos . Gorgias also addresses temporality, which not only imposes existential limits on human capacity but also contours language itself. Ultimately, the Helen conducts third-order (self-reflexive) thinking by marshalling a battery of rhetorical resources designed to attune an audience to how their own participation in the logos generates and sustains its powers. In effect, what the Helen is about is the work that the Helen does. Through a mixture of new insights into persuasion, language, temporality, and psychology, combined with self-reflexive rhetorical work, the Helen inspires further thought about key aspects of Greek existence.
Performance evaluation of a UOWC system based on the FRS/OCDMA code for different types of Jerlov waters
Authors: Abd El-Mottaleb Somia A. , Singh Mehtab , Atieh Ahmad , Aly Moustafa H.
Published: December 2023

In this work, the fixed right shift (FRS) code is utilized for the optical code division multiple access (OCDMA) technique in an underwater optical wireless communication (UOWC) system. Additionally, in this system, a 532 nm laser diode (LD) source is employed to generate optical signals. The investigation encompasses an analysis of five distinct Jerlov water types, each exhibiting diverse chlorophyll concentrations. The performance of the proposed system is evaluated when each channel that is assigned a unique FRS code sequence carries different data rates (2.5, 5, and 10 Gbps). Underwater (UW) ranges, bit error rate (BER), eye diagrams, and quality factor (Q-factor) are the performance metrics used to evaluate the system performance. The proposed UOWC-FRS/OCDMA system is simulated, and the obtained results show that the eye diagram openings close, the BER increases, and the Q-factor decreases as the data rate per each channel increases from 2.5 to 10 Gbps, and the attenuation of water becomes higher. Moreover, the lower attenuation values caused by the Jerlov type I (JI) waterbody allow each channel to carry 10 Gbps of data to propagate longer UW for a range of 35 m with a log(BER) ≤−6.33 and Q-factor greater than 4.9. On the other hand, at the same values of BER and Q-factor, the shortest ranges of 12 and 5.15 m are obtained for JII and JIII waters, respectively, where their attenuation coefficient values are 0.5297 (JII) and 1.8998 m−1 (JIII). Furthermore, as our model uses three channels, the overall achieved capacity is 3×10Gbps=30Gbps.
DRL-enabled cooperative free-space optical communication system with an elastic optical splitter
Authors: Liu Yejun , Wang Xi , Liao Shasha , Sun Qiming , Feng Shuhua , Guo Lei
Published: December 2023

Cooperative communication has been widely studied as an effective technique for free-space optical (FSO) systems to combat the effects of atmospheric conditions and beam misalignment. Related works on cooperative FSO communication mostly used a fixed splitter to uniformly distribute optical power for broadcast transmission, which tends to cause the insufficient utilization of optical power when the relay links have different channel statuses. In this paper, we focus on the optical power utilization of cooperative FSO communication, which remains less touched in previous works, while it is a decisive factor in system performance. We propose an elastic optical splitter structure to improve the efficiency of optical power by dynamically adjusting its optical output to the changing atmospheric channels. The elastic optical splitter brings a new chance for the relay selection and power allocation, which will become a different issue from that in traditional cooperative FSO systems. Thus, we further propose an adaptive relay selection and power allocation scheme using a deep reinforcement learning algorithm. Results demonstrate that the proposed elastic optical splitter is superior to the fixed optical splitter for cooperative FSO communication in bit error rate (BER) by a performance improvement of 1 to 2 orders of magnitude. Along with the proposed adaptive relay selection and power allocation scheme, the performance is further improved by more than 25% under different channel conditions.
Generative Artificial Intelligence: Fundamentals
Authors: Corchado Juan M. , López F. Sebastian , Núñez V. Juan M. , Garcia S. Raul , Chamoso Pablo
Published: December 2023

Generative language models have witnessed substantial traction, notably with the introduction of refined models aimed at more coherent user-AI interactions—principally conversational models. The epitome of this public attention has arguably been the refinement of the GPT-3 model into ChatGPT and its subsequent integration with auxiliary capabilities such as search features in Microsoft Bing. Despite voluminous prior research devoted to its developmental trajectory, the model’s performance, and applicability to a myriad of quotidian tasks remained nebulous and task specific. In terms of technological implementation, the advent of models such as LLMv2 and ChatGPT-4 has elevated the discourse beyond mere textual coherence to nuanced contextual understanding and real-world task completion. Concurrently, emerging architectures that focus on interpreting latent spaces have offered more granular control over text generation, thereby amplifying the model’s applicability across various verticals. Within the purview of cyber defense, especially in the Swiss operational ecosystem, these models pose both unprecedented opportunities and challenges. Their capabilities in data analytics, intrusion detection, and even misinformation combatting is laudable; yet the ethical and security implications concerning data privacy, surveillance, and potential misuse warrant judicious scrutiny.
Book Review of the Book The Wealth of Religions - The Political Economy of Believing and Belonging by R. J. Barro and R. M. McCleary
Authors: Lits Benedek
Published: December 2023

The Wealth of Religions by Barro and McCleary is an epoch-making work of the inter-discipline of religious studies and development economics, an eight-chapter summary of sixteen years of research and seminar work. The topic is very up-to-date, eye-catching, and provocative to some extent, considering the fact that politics, economics, and religion remain divisive topics in most societies today. In an era of renewal of religious terrorism, religious wars, and religious discrimination, writing this book shows a brave commitment to freedom, justice, and universal prosperity. Barro and McCleary, coming from an economic and a moral philosopher background, respectively, have published plenty of academic papers, while simultaneously running the class Political Economy of Religions at Harvard on topics they write about in this book, published by the Princeton University Press.
Entre la patria y la madre patria: imaginarios de la (in)movilidad a España en la sección de comentarios de «Clarin.com»
Authors: Navarro-Conticello Jose
Published: December 2023

La prensa argentina y la española han participado activamente en la historia de movilidades entre ambos países, difundiendo en sus discursos imaginarios sociales favorables a la emigración. Este artículo estudia la recepción de tales mensajes por sus audiencias, indagando en la categoría de imaginarios de la (in)movilidad, que considera tanto la movilidad como la permanencia. Se aplicó un análisis de contenido cualitativo a 310 comentarios de lectores y lectoras en una serie de artículos periodísticos del diario online argentino Clarin.com sobre un eventual asentamiento de argentinos y argentinas en España. Los resultados evidencian una distribución heterogénea de los imaginarios en torno a los ejes inmovilidad-movilidad y origen-destino. Predominan los imaginarios de la movilidad, aunque suelen estar asociados a valoraciones negativas del país de origen más que a evaluaciones positivas del país de destino. Asimismo, se observa un importante componente ideológico y fuertes disputas sobre la idoneidad de España como destino.

Published: December 2023

The glass-crystalline ceramic materials in SiO2–Al2O3–RO (RO–MgO, SrO, BaO and their combinations) systems have been synthesized by the sol-gel method. The factors influencing on the sol-gel formation process are revealed. The effect
of the composition and temperature-time modes of heat treatment on the crystallization properties of gels, phase transformations, phase composition, granulometry and shape of the resulting particles has been studied. The nature of phase transformations in powders is revealed depending on the temperature-time conditions of heat treatment. It is shown that the dominant crystalline phases, depending on the composition, are anorthites or their solid solutions, their formation temperatures have been established: hexagonal celsian is formed at a temperature of 1350 °C, monoclinic strontium anorthite – at 1400 °C, cordierite – at 1450 °C. The influence of pressing and heat treatment conditions on the physic-mechanical, dielectric and thermal properties of the obtained materials is investigated.
The synthesized glass-ceramics with low dielectric constant and dielectric loss tangent, high deformation temperatures (above 1500 °C) is a promising replacement for the spodumene-eucryptite and cordierite sitalls currently used as radio-transparent materials, the disadvantage of which is insufficiently high operating temperatures (not higher 900 – 1100 °C).

KIT DESIGNING FOR ASSESSING ROS AND SCD IN SEMEN: REPLICATION OF METHODOLOGY WHO LABORATORY MANUAL (2021) IN TO RUSSIAN LABORATORY PRACTICE
Authors: Davidova Zh. Yu.
Published: December 2023

According to WHO laboratory manual for the examination and processing of human semen, sixth edition (2021) [1], there are a number of techniques available to measure ROS (Reactive Oxygen Species) and DFI levels in semen and each of them has its inherent limitations. According to WHO (2021), two methods for measuring ROS and DFI seems to be attractive due to reliability and simplifying of performance not only in laboratory conditions but also in point-of-care (POC) one. Russian technique utilizes Tetrazolium Nitroblue for measuring ROS which kit named ‘OxySperm (NBT-assay)’ and SCD-assay named ‘HaloSperm’ have been replicated and upgrade methods compared to WHO (2021) and another fundamental scientific papers. Both kits showed not only reproducible results compared with WHO (2021) but also have technological advantages over the previous described methods. This publication presents step-by-step operational procedures of novel Russian kits.

Authors: Barat V. A. , Marchenkov A. Yu. , Karpova M. V. , Bardakov V. V. , Ushanov S. V.
Published: December 2023

The paper investigates the possibility of detecting specific structural defects of dissimilar welded joints by the method of acoustic emission (AE). Carbide and decarburized interlayers are formed in dissimilar welded joints of austenitic and pearlitic steels during welding and subsequent operation. Diffusion interlayers, as a structural defect, are usually small in size and cannot be detected by traditional non-destructive testing (NDT) methods, while the AE method is promising for detecting such defects. In the present work, we studied the AE data obtained during testing of defect-free specimens of a welded joint and specimens with diffusion interlayers. It has been established that the AE parameters for defective and defect-free welded joints have significant differences, which makes it possible to identify the presence of diffusion interlayers in dissimilar welded joints.

INVESTIGATION OF THE TEMPERATURE ERROR OF COORDINATE MEASURING MACHINES
Authors: Iskenderzade E. B. , Ahmedova Sh. V.
Published: December 2023

Coordinate measuring machines are widely used for technological control of geometric parameters of the surface of various parts in many branches of industrial production. For coordinate measurements of high-precision surfaces, instrumental sources of error can be minimized if the axes of the controlled object are located on the same axis of the reference scale of the comparator or parallel to it. However, in all schemes of construction of coordinate measuring machines, the Abbe principle is violated, which leads to the appearance of a measurement error, which, moreover, increases with the increase in the overall dimensions of the coordinate machine. It is determined that the total error can be determined taking into account two factors: the maximum allowable error calculated without taking into account the temperature variations of the measured object itself; the temperature change of the measured object. It is shown that the resulting error of coordinate measuring machines can be investigated on the basis of the optimization problem of calculating the optimal form of the function of the temperature dependence of the object on time. It is shown that the resulting error integrated in time will reach a minimum value if the temperature dependence functions of the measured object T(t) and the coefficient of thermal expansion α(t) change synchronously in time. Therefore, in order to minimize the error of coordinate measuring machines from changes in time of such indicators as T and α must occur synchronously, i.e. their change in time must satisfy the corresponding certain condition. To quantify the gain in optimizing measurements, we will conduct a model study. To estimate the gain in reducing the error, two model functions have been compiled, the integrals of which, according to a certain condition, must be equal to the integral of the calculated coupling function. It is shown that according to the calculation, the lowest estimate of the reduction of the measurement error with the proposed optimization will be 4.5 %.

Authors: Grachev M. I.
Published: December 2023

In this article, a study on enterprise automation is carried out. A variant of partial automation of the organization's work is proposed, based on the model obtained in the article for evaluating the effectiveness of the implementation of the management decision of the head of the organization. When faced with problems in the work of an enterprise, the head should have a solution model that allows him to respond to the problem in a timely manner and solve it with the necessary level of implementation of the management solution. In this article, the model is based on synthesis. The resulting model of a management decision allows you to get an indicator of the effectiveness of the implementation of a management decision. The obtained indicator of the effectiveness of the management decision characterizes the parameters of the system under consideration consisting of a hardware and software complex and personnel. By setting the required level of the indicator of the effectiveness of the implementation of a management decision and solving the inverse problem, we can obtain the required time indicators of the human-machine system, in order to guarantee the achievement of the goal of the organization's activities with a given level of indicator. The indicator of the effectiveness of a management decision obtained in the work allows you to obtain the necessary information about the organization under study, thereby implementing automation of management processes.

Authors:   South Ural State University, Chelyabinsk, Russian Federation, Sharutina О.
Published: December 2023

The reaction of penta(para-tolyl)antimony with ferrocene carboxylic acid in benzene (heat-ing at 80 °C for 15 minutes) leads to the formation of tetra(para-tolyl)antimony ferrocene car-boxylate (4-MeC6H4)4SbOC(O)C5H4FeC5H5 (1). Complex 1 has been characterized by IR spec-troscopy, and its structure has been established by X-ray diffraction analysis. The IR spectrum of 1, recorded on a Shimadzu IRAffinity-1S FTIR spectrometer in KBr matrix contains bands characterizing the vibrations of the Sb–C, Sb–O bonds, the CO2-group, and the ferrocene frag-ment in the range of 4000–400 cm–1. The X-ray structural analysis of the complex was carried out on an automatic four-circle D8 Quest Bruker diffractometer (МоКα-radiation, λ = 0.71073 Å, graphite monochromator) at 293 K. Crystallographic characteristics of 1: triclinic syngony, space group P-1, a = 11.02(2), b = 13.00(2), c = 13.519(19) Å,  = 68.92(5), β = 81.26(7),  = 65.71(7) deg., V = 1648(5) Å3, Z = 2, calc = 1.442 g/cm3, 2 5.674.32 deg., total reflections 96987, independent reflections 16158, number of refined parameters 392, Rint = 0.0701, GOOF 1.060, R-factors for F2 > 2σ(F2) R1 = 0.0829, wR2 = 0.2390, R-factors for all reflections R1 = 0.1224, wR2 = 0.2597, residual electron density (max/min), 3.38/2.04 e/Å3. In the monomeric molecule of crystal 1 the coordination of the antimony atom is distorted octahedral, due to the fact that the carboxylate ligand is a bidentate chelating one. The diagonal angles in the octahedron are 147.5(2), 156.7(2), 167.0(2). The Sb–O(1) and Sb–O(2) distances are 2.475(6) and 2.313(5) Å, the Sb–C bonds differ significantly (2.114(6), 2.142(6), 2.152(6), 2.168(6) Å). The structural organization of the crystal is mainly due to the С–Н•••-type interactions.

first decade of terminal restriction fragment length polymorphism (T-RFLP) in microbial ecology
Authors: STRES Blaž
Published: December 2023

Terminal restriction fragment length polymorphism (T-RFLP) was introduced to environmental microbiology only a decade ago but it soon became a molecular tool of choice, due to its high throughput and phylogenetic resolution. Fierce discussions accompanied the new method leading to sophistication of the data preparation, acquisition, manipulation and standardization of analysis. Consequently, numerous approaches were proposed at various steps and also criticized. As a result, a combination of variable percentage threshold and Bray-Curtis index used in non-metric multidimensional scaling are now being accepted. Their combination offers a balance between noise elimination and information retention yielding a powerful and yet easily interpreted method to examine community patterns based on T-RFLP data. Its current state of the art and future developments highlight the potential of the method in the field of microbial ecology. However, a more standardized approach and a higher level of control at all stages of T-RFLP fingerprinting are needed.
Postsekularyzm między Wschodem i Zachodem
Authors: Obirek Stanisław
Published: December 2023

The aim of the article Postsecularism between East and West is to present the paradigm shift in understanding the place of religion in public space in recent decades. The term that aptly describes this change is postsecularism. The prefix “post” is more than just an indication of a new quality of “secularism.” In fact, it marks a revolutionary change in understanding the traditionally opposing concepts of secularism and religion. The article presents this process in three stages. First, it describes the theological turn that has taken place in recent decades, primarily in Catholic theology, then it points to the place of literature in theological reflection and finally presents the surprising contribution of the mathematical concept (fractal) in overcoming the impasse in which interreligious dialogue found itself.

Environmentally sustainable analytical quality by design aided RP-HPLC method for the estimation of brilliant blue in commercial food samples employing a green-ultrasound-assisted extraction technique
Authors: Chakraborty Atyurmila , Jayaseelan Kavitha
Published: December 2023

Brilliant blue FCF (E133) is a commonly employed azo synthetic dye in the food industry owing to its visually appealing color and widespread consumer acceptance. The health risks associated with the excessive use of brilliant blue necessitate prioritizing eco-friendly methods for its quantification. The purpose of this study is to develop and validate an analytical quality by design (AQbD) based eco-friendly high-performance liquid chromatography method adhering to the 12 principles of green chemistry followed by ultrasound-assisted extraction of food samples and confirming them using Fourier transform infrared spectroscopy. Rotatable central composite designs (CCDs) were utilized to optimize the chromatographic parameters. The separation was achieved on a Phenomenex column (Luna C18, 250 mm × 4.6 mm, i.d. 5 μm) employing ethanol and acetate buffer as a mobile phase in the ratio 25:75 (v/v) at a flow rate of 1 mL·min−1 with detection at 626 nm, which resulted in elution of brilliant blue at 2.692 min. The developed method fulfills the predetermined requirements of linearity, accuracy, sensitivity, and reproducibility at the specified working point. The green analytical procedure index, analytical eco scale, and analytical greenness metrics were used for assessing greenness, which yielded the most benign outcomes. In the future, this research could lead to the adoption and enhancement of eco-friendly robust AQbD methodologies for evaluating various food colorants, utilizing green solvents.

Published: December 2023

The present research is characterized by ecofriendly, low cost and robust methods to synthesize calcium hydroxide (CH) nanoparticles using clove oil as capping and reducing agent and nonionic block copolymers as surface modifiers and particle size reducers. The prepared nanoparticles were characterized using UV–visible spectroscopy, dynamic laser light scattering, X-ray diffraction, Fourier transform infra-red spectroscopy, energy dispersive X-ray spectroscopy and transmission electron microscopy. The average effective diameter and crystallite size of particle calculated from DLS and XRD were 97–178 and 22–36 nm respectively. The synthesized NPs showed excellent catalytic activities against Allura red and Fast green dye. They also showed improved anti-bacterial and antifungal activities against Staphylococcus aureus, Klebsiella pneumonia and Candida albicans with minimum inhibitory concentration of 50 μl ml−1. The prepared nanocrystals were also incorporated into gum Arabic to be used as consolidant for archaeological bone fragments to fill the cracks, reinforce their mechanical features and save them from further decay. The SEM images of all the bone fragments before and after treatment clearly specify the effectiveness of this treatment.

In brief

Cattle are classified as having synepitheliochorial placentation in which the majority of the uterine luminal epithelial cells remain intact with some luminal epithelial cells fusing with binucleate trophoblast cells to form syncytial trinucleate cells. This study suggests the possibility that, for a limited and as yet undefined period of gestation, the majority of luminal epithelial cells are eliminated and replaced by trophoblast cells that express pregnancy-associated glycoproteins.

What we understand about the early stages of placentation in cattle is based on an elegant series of electron microscopic images that provide exquisite detail but limited appreciation for the microanatomy across the uteroplacental interface. In order to achieve a global perspective on the histology of bovine placentation during critical early stages of gestation, i.e., days 21, 31, 40, and 67, we performed immunohistochemistry to detect cell-specific expression of pregnancy-associated glycoprotein (PAG), cytokeratin, epithelial (E)-cadherin, and serine hydroxymethyltransferase 2 (SHMT2) at the intact uteroplacental interface. Key findings from the immunohistochemical analyses are that there are: (i) PAG-positive cells with a single nucleus within the uterine luminal epithelial (LE) cells; (ii) PAG-positive cells with two nuclei in the LE; (iii) PAG-positive syncytial cells with more than three nuclei in the LE; (iv) LE cells that are dissociated from one another and from the basement membrane in regions of syncytialization within the LE layer; (v) replacement of the mononuclear LE with a multilayer thick population of PAG-positive cells invading into the uterine stroma of caruncles but not into the stroma of intercaruncular endometrium; and (vi) PAG-, E-cadherin-, and SHMT2-positive mononuclear cells at the leading edge of developing cotyledonary villi that eventually represent the majority of the epithelial surface separating caruncular stroma from cotyledonary stroma. Finally, the uteroplacental interface of ruminants is not always uniform across a single cross section of a site of placentation, which allows different conclusions to be made depending on the part of the uteroplacental interface being examined.

El cuerpo expuesto. Implicaciones políticas de los procedimientos de subjetivación del trabajo
Authors: López Álvarez Pablo
Published: December 2023

La presencia del problema del trabajo en las reflexiones filosóficas y políticas contemporáneas es persistente y ambigua. El ascenso de las formas neoliberales de gobierno social se vinculó con una profunda reconsideración de la naturaleza del trabajo y su modo de organización, e incluyó la revalorización de la autonomía y la subjetividad en la actividad laboral. El presente artículo se centra en los procesos de individualización y subjetivación del trabajo para estudiar algunos de sus efectos políticos y mostrar su relevancia en el presente escenario de crisis de legitimación de los órdenes neoliberales. El trabajo se muestra como un ámbito determinante para la comprensión de las políticas del cuerpo, la fragmentación de la acción social y los patrones contemporáneos de producción de subjetividad.
Problemas epistemológicos de la predicción en los modelos de Equilibrio General Dinámico y Estocástico (EGDE)
Authors: Barrientos Apumayta Enrique Agapito
Published: December 2023

Este artículo destaca el impacto y la crítica a los presupuestos teóricos de la predicción en los modelos EGDE, además de sus alcances y límites en materia de política económica realizada por los bancos centrales. Hemos elegido temas diversos para explicar los fenómenos predictivos en ciencias sociales y, principalmente, en economía, basados en la econofísica, econometría y la macroeconometría aplicados a los modelos EGDE, pero estos giran en torno al problema mente-cerebro y a la “teoría de la cognición de codificación predictiva”. Conceptualizamos sus aportes a través de problemas epistemológicos y los relacionamos con su aplicación a los modelos EGDE. Así, pretendemos enfatizar la tarea de nuestra crítica para abrir el campo de análisis de las teorías de la predicción hacia los sistemas complejos en ciencias sociales y otros debates epistémicos. Por lo tanto, se defiende la tesis de las limitaciones en la predicción bajo el concepto del cerebro como motor de predicción para dar un aporte de una posible concepción epistemológica de la predicción en ciencias naturales y sociales.

Juzgado de Familia Número 6: autoficción, autorreferencialidad compleja y lo real
Authors: Causillas Fonseca Tirso José
Published: December 2023

El presente estudio explora las relaciones entre autoficción, escena y lo real desde las reflexiones generadas en el proceso creativo de Juzgado de Familia Número 6, obra autoficcional que aborda la relación entre la mujer y la ley en el Perú, haciendo énfasis en la posibilidad de construir algo desde el trauma. Para estos fines, se apoya en las premisas de la investigación desde el arte, sobre todo en su dimensión autorreflexiva y crítica. Por otro lado, se asume a la autoficción como una estrategia narrativa que establece al “yo” como en permanente construcción. Ambos caminos se entrecruzan en lo que elegimos llamar autorreferencialidad compleja. Finalmente, se reflexiona en torno al trauma como lo irrepresentable y como límite de la práctica creativa.
El efecto del ritmo en el discurso dramático de Colacho hermanos (1934) de César Vallejo
Authors: Ventura Vásquez Williams Nicks
Published: December 2023

Los estudios sobre la poesía, los cuentos y las novelas de César Vallejo evidencian el proceder poético y la exhaustiva búsqueda por elaborar una composición artística innovadora. Ese mismo ánimo literario se percibe también en el aspecto teatral, pues sus acercamientos teóricos y propuestas teatrales demuestran el interés por replantear la dramaturgia de su época como lo realiza en Colacho hermanos (1934). Esta obra, si bien resalta el problema político, social y económico de la sociedad peruana, desarrolla una incesante labor por conseguir un discurso teatral vinculado a su inclinación estética. Por ello, desde un análisis semiológico y rítmico, la presente investigación verifica la composición del diálogo dramático en la pieza teatral del afamado vate.
La otra escena en El lenguaje de las sirenas de Mariana de Althaus
Authors: Gallegos Santiago Óscar Giovanni
Published: December 2023

El presente artículo tiene el objetivo de demostrar cómo lo fantástico en conjunción con nociones como lo “cholo” y el “taki onkoy” se potencian para abrir nuevas perspectivas con respecto a los clásicos conceptos de discurso, poder e ideología. Para ello, se analiza la obra teatral El lenguaje de las sirenas (2012) de la escritora peruana Mariana de Althaus, en la que aparece una “sirena chola” varada en la orilla de una playa peruana. Es en ese momento en que el canto de esta sirena (taki onkoy) mestiza confrontará no solo las prácticas y discursos de los personajes, sino también su cosmovisión occidental, su condición subalterna y el ruido frenético del capital previo al verdadero horror. Por ello, más que analizar lo que se dice en la obra, nos interesa captar el rumor de lo no dicho, lo intersticios de este silencio milenario, lo incomprensible de esa “otra escena”.
