Marginación y olvido en la poesía femenina española: Tres poetas de los ochenta.
Authors:   Universidad Autónoma de Guadalajara, Rodríguez-Jiménez Antonio
Published: September 2024

La lírica de la década de los ochenta del pasado siglo en España viene marcada por el desafío contra la uniformidad de un discurso único pergeñado por un grupo de críticos, antólogos y editores afines empeñados en resucitar a toda costa la poesía social del medio siglo, que protagonizaron poetas como Jaime Gil de Biedma, Ángel González, Carlos Barral y José Manuel Caballero Bonald, entre otros. Si para los poetas fue difícil abrirse camino unos años después, donde se impone una nueva poesía social inspirada en los antes citados, para las poetas de los 80 lo fue más aún, ya que venían dispuestas a renovar el panorama y fueron marginadas. El objetivo de este estudio es demostrar cómo de un ramillete de docenas destacaron por su personalidad creadora y su estilo original y extraordinario. La metodología de este estudio es puramente cualitativa, basada en lecturas de textos, críticas de la época y estudios posteriores de especialistas. En conclusión, Blanca Andréu, María Antonia Ortega y Concha García demostraron ser sobresalientes poetas en una época en la que el hombre era el dominante y se apartaba tanto mujeres como a otros poetas que no pertenecieran a la línea hegemónica.
Reading My Father’s Leggìo: An Autotopography of Mourning in Translation
Authors: Basile Elena
Published: September 2024

This essay is part of a wider project of autoethnographic exploration of the memory- and place-making function that keepsake objects perform in the context of the multi-scalar and more-than-human temporalities of colonial modernity and its pervasive geographies of displacement. In it, I engage in quiet conversations with an object associated with my father’s life, illness, and death in Bari, Italy – a wooden bookstand, or leggìo, which my father made out of repurposed wood. For over twenty years, this leggìo actively interacted with my spaces of migrant dwelling, affectively modulating my discomfited sense of hyphenated belonging among urban domestic interiors in Canada – at times attenuating my internal displacements and longings and at others amplifying them. This essay converses with the strange animacy accrued by the leggìo over the decades, at first just triggering my own personal memory work, but then moving outward into more difficult and demanding ethical questions about environmental stewardship and decolonial futurity, once I start interrogating the object’s material components and their manufactured provenance.
Sobre a transição comunista na URSS: uma crítica da teoria da revolução socialista. Lenin e o significado histórico da sua proposta de capitalismo de estado
Authors: De Lima Filho Paulo Alves de Lima Filho
Published: September 2024

A inédita transição ao comunismo colocada na história pela Revolução Russa de 1917, obrigou seus líderes teóricos a resolverem a tarefa de conceber e levar a contento tal transição. Lenin foi, sem dúvida, quem mais se aproximou a desvendar tal processo, em disputa com a maioria dos teóricos, embora ainda tenha carregado o ônus do equívoco da teoria da revolução socialista, de matriz lassalleana, que nada tem a ver com Marx. A teoria de Lenin sobre o capitalismo de estado bem demonstra a riqueza de seu pensamento, ao revelar a necessária raiz comunista da transição, e os elementos necessários e obrigatórios para uma transição que se mantivesse fiel à tarefa de emancipação dos trabalhadores.

A New Approach Using the Lindley Distribution in Stochastic Frontier Analysis
Authors: Yenilmez İsmail
Published: September 2024

Abstract
Stochastic Frontier Analysis plays a crucial role in assessing technical efficiency and modelling production processes across various disciplines. Traditionally, SFA assumes specific error distributions, such as the normal distribution for random effects and the half-normal distribution for technical efficiency. However, the choice of error distributions can significantly impact model estimation and interpretation. This study proposes a novel approach by incorporating the Lindley distribution as a flexible error distribution in SFA, termed Lindley Stochastic Frontier Analysis (L-SFA). This extension offers a more detailed representation of the error structure, potentially enhancing the accuracy of efficiency estimates. The derivation and solution of maximum likelihood estimators for the theoretical foundations of L-SFA are provided. Furthermore, a simulation study demonstrates the advantages of L-SFA over traditional SFA. The findings underscore the importance of flexible error distributions in capturing the complexities of production processes with this new SFA extension.

Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disease characterized by the accumulation of fat in the liver in the absence of excessive alcohol consumption or a secondary cause of hepatic steatosis. The prevalence of NAFLD is increasing worldwide and its management has become a public health concern. Animal models are traditionally used to elucidate disease mechanisms and identify potential drug targets; however, their translational aspects in human diseases have not been fully established. This study aimed to clarify the utility of animal models for translational research by assessing their relevance to human diseases using gene expression analysis. Weighted gene co-expression network analysis of liver tissues from Western diet (WD)-induced NAFLD mice was performed to identify the modules associated with disease progression. Moreover, the similarity of the gene co-expression network across species was evaluated using module preservation analysis. Nineteen disease-associated modules were identified. The brown module was positively associated with disease severity, and functional analyses indicated that it may be involved in inflammatory responses in immune cells. Moreover, the gene co-expression network of the brown module was highly preserved in human NAFLD liver gene expression datasets. These results indicate that WD-induced NAFLD mice have similar gene co-expression networks (especially genes associated with inflammatory responses) to humans and are thought to be a useful experimental tool for preclinical research on NAFLD.

A comprehensive analysis of the deposits of the paleo-reservoir represented in the Kulikovo section (the northern part of the Sambian Peninsula) has been carried out. According to results of radiocarbon dating, the deposits formed approximately from 14100 to 12900 cal yr BP. The most detailed data were obtained for the lower part of the section (depth 192–141 cm), comprising the Older Dryas and the first half of the Allerød. Results of a comprehensive lithological, diatom, spore-and-pollen analysis and algo-zoological microfossil analysis allowed us to identify 8 stages of the sedimentation conditions of the paleo-reservoir.

Objective: The aim of this study is to compare the difference between original lateral cephalometric radiographs (LCRs) and Contrast Limited Adaptive Histogram Equalization (CLAHE) LCRs in two examiners and WebCeph.
Methods: A total of 200 LCRs were selected, and CLAHE (tile size: 20*20) was applied to the original LCRs. 27 LCR landmarks were manually determined by two examiners and, the selected LCR’s determined automatically using the WebCeph program. Absolute differences between the original LCRs and CLAHE-LCRs were calculated in the x-y axes and Euclidean distance. The Kruskal Wallis test was used for comparisons
between the examiners and WebCeph. The Wilcoxon Signed Rank Test was used to evaluate the x and y axes within each group.
Results: The best accuracy values were seen in examiner 1 along the x-y axes and Euclidean distance, while the worst accuracy values were seen in WebCeph. The mean differences according to the methods were higher along the y-axis than along the x-axis for both examiners (except PNS, Me’) and WebCeph (except Po, Co). The mean Euclidean distances were above 2 mm only in Co, PNS at Examiner 1, PNS, Po, Ba, Co, Go, Pog, U1RT, Me’, Pog at Examiner 2, and WebCeph in all measurements. However, the differences in Euclidean distances were less than 4 mm for both examiners and WebCeph.
Conclusion: CLAHE-LCRs require more adjustments for landmark determination in WebCeph than the in the manual system.

Introduction

Osteoporosis-induced changes in bone structure and composition significantly reduce bone strength, particularly in the human proximal femur. This study examines how these changes affect the mechanical performance of trabecular bone to enhance diagnosis, prevention, and treatment strategies.

Methods

A proximal femur sample was scanned using micro-CT at 40 μm resolution. Five regions of interest were selected within the femoral head, femoral neck, and greater trochanter. Structural models simulating various stages of osteoporosis were created using image processing software. Micro-finite element analysis evaluated the mechanical properties of trabecular bone under different conditions of structural deterioration and tissue-level elastic modulus variations. The combined effects of structural deterioration and tissue-level mechanical properties on trabecular bone mechanical performance were further analyzed.

Results

The mechanical performance of trabecular bone generally follows a power-law relationship with its microstructural characteristics. However, in any specific region, the apparent mechanical properties linearly decrease with structural deterioration. The femoral neck and greater trochanter are more sensitive to structural deterioration than the femoral head. A 5% bone mass loss in the femoral head led to a 7% reduction in mechanical performance, while the femoral neck experienced a 12% loss. Increasing tissue-level elastic modulus improved mechanical performance, partially offsetting bone mass reduction effects.

Conclusion

Trabecular bone in low bone mass regions is more affected by bone mass loss. Structural deterioration primarily reduces bone strength, but improvements in tissue-level properties can mitigate this effect, especially in early osteoporosis. Targeted assessments and interventions are crucial for effective management. Future research should explore heterogeneous deterioration models to better understand osteoporosis progression.

With outstanding therapeutic potential in the tissue regeneration and anti-inflammation, mesenchymal stem cell-derived exosomes (MSC-EXOs) have emerged as a prominent therapeutic in recent. However, poor production yield and reproducibility have remained as significant challenges of their practical applications. To surmount these challenges, various alternative materials with stem cell-like functions, have been recently investigated, however, there has been no comprehensive analysis in these alternatives so far. Here, we discuss the recent progress of alternatives of MSC-EXOs, including exosomes and exosome-like nanovesicles from various biological sources such as plants, milk, microbes, and body fluids. Moreover, we extensively compare each alternative by summarizing their unique functions and mode of actions to suggest the expected therapeutic target and future directions for developing alternatives for MSC-EXOs.

This study predicted the fatigue life (N) of UHPC incorporated with different volume fractions (Vf = 0.0%, 0.5%, 1.0%, 1.5% and 2.0%) of steel fiber under flexural cyclic loading at various stress levels (S). The Weibull distribution, a two-parameter model, was utilized to estimate the distribution of fatigue life in UHPC. Subsequently, three methods were employed to calculate the parameters: the graphical method, the method of moments, and the method of maximum likelihood. The averaged values of these parameters were then obtained to enhance the accuracy of the estimation. The results are presented in the form of S-N diagrams, which depict the quantitative relationship between stress (S) and fatigue life (N). This relationship was determined using the Wohler equation, the modified Wohler equation, and the power equation. By employing these equations, the flexural fatigue strength of UHPC can be accurately predicted. Subsequently, the fatigue failure probability (Pf) was incorporated to enhance the reliability of the S-N quantitative relation. The fatigue testing results were presented in the form of S-N-Pf curves, which comprehensively reflect the relationship between stress, fatigue life, and failure probability. Furthermore, the mathematical relation of the S-N-Pf curves was derived to predict the fatigue life of UHPC with a given failure probability, providing a more comprehensive and accurate assessment of its fatigue behavior.

Background

There has been growing recognition of non-ischemic etiologies of cardiogenic shock (CS). To further understand this population, we aimed to investigate differences in clinical course between acute on chronic heart failure related (CHF-CS) and de-novo CS (DN-CS).

Methods

Using the Nationwide Readmission Database, we examined 92,426 CS cases. Outcomes of interest included in-hospital and 30-day outcomes and use of advanced heart failure therapies.

Results

Patients with DN-CS had higher in-hospital mortality than the CHF-CS cohort (32.6% vs. 30.4%, p < 0.001). Mechanical circulatory support (11.9% vs. 8.6%, p < 0.001) was more utilized in DN-CS. Renal replacement therapy (13.8% vs. 15.5%, p < 0.001) and right heart catheterization (16.0% vs. 21.0%, p < 0.001) were implemented more in the CHF-CS cohort. The CHF-CS cohort was also more likely to undergo LVAD implantation (0.4% vs. 3.6%, p < 0.001) and heart transplantation (0.5% vs. 2.0%, p < 0.001). Over the study period, advanced heart failure therapy utilization increased, but the proportion of patients receiving these interventions remained unchanged. Thirty days after index hospitalization, the CHF-CS cohort had more readmissions for heart failure (1.1% vs. 2.4%, p < 0.001) and all causes (14.1% vs. 21.1%, p < 0.001) with higher readmission mortality (1.1% vs. 2.3%, p < 0.001).

Conclusion

Our findings align with existing research, demonstrating higher in-hospital mortality in the DN-CS subgroup. After the index hospitalization, however, the CHF-CS cohort performed worse with higher all-cause readmission rate and readmission mortality. The study also underscores the need for further investigation into the underutilization of certain interventions and the observed trends in the management of these CS subgroups.
