The Southern Picturesque: Visions of the New and Old South in the Lower Mississippi River Valley
Authors: Norwood Bryan E.
Published: March 2023

This essay examines the southern picturesque, an architectural vision of the Old South formulated in the 1910s through 1930s in the Lower Mississippi River valley. This vision offered an oblique approach to the plantation big house that evoked a mythical antebellum past, presenting this fulcrum of chattel slavery and resource extraction as an image of leisurely natural order where climate assumed primary importance in the shaping of architectural form. Drawings and texts composed by architect and Tulane University professor Nathaniel Curtis, architect-artist William Spratling, and writer Natalie Scott participated in this maudlin display of the Old South. As this article argues, their work represented a kind of partially uprooted modernism that was in fact made possible by the expansion of the oil industry into the very same environment celebrated by the southern picturesque for its agrarian, nonindustrial authenticity.

Cognitive decline is a common pathological outcome during aging, with an ill‐defined molecular and cellular basis. In recent years, the concept of inflammaging, defined as a low‐grade inflammation increasing with age, has emerged. Infiltrating T cells accumulate in the brain with age and may contribute to the amplification of inflammatory cascades and disruptions to the neurogenic niche observed with age. Recently, a small resident population of regulatory T cells has been identified in the brain, and the capacity of IL2‐mediated expansion of this population to counter neuroinflammatory disease has been demonstrated. Here, we test a brain‐specific IL2 delivery system for the prevention of neurological decline in aging mice. We identify the molecular hallmarks of aging in the brain glial compartments and identify partial restoration of this signature through IL2 treatment. At a behavioral level, brain IL2 delivery prevented the age‐induced defect in spatial learning, without improving the general decline in motor skill or arousal. These results identify immune modulation as a potential path to preserving cognitive function for healthy aging.
Metastatic follicular thyroid cancer with a longstanding responsiveness to gemcitabine plus oxaliplatin
Authors: Dias Daniela , Damásio Inês , Marques Pedro , Simões Helder , Rodrigues Ricardo , Cavaco Branca Maria , Leite Valeriano
Published: March 2023

Background

Treatment of advanced follicular thyroid carcinoma (FTC) is based primarily on indirect evidence obtained with multikinase inhibitors (MKI) in clinical trials in which papillary carcinomas represent the vast majority of cases. However, it should be noted that MKI have a non-negligible toxicity that may decrease the patient’s quality of life. Conventional chemotherapy with GEMOX (gemcitabine plus oxaliplatin) is an off-label therapy, which seems to have some effectiveness in advanced differentiated thyroid carcinomas, with a good safety profile, although further studies are needed.

Case report

We report a case of a metastatic FTC, resistant to several lines of therapy. However, with a durable response to GEMOX, the overall survival of our patient appears to have been extended significantly due to this chemotherapy.

Conclusion

GEMOX may have a role in patients with thyroid cancer unresponsive to MKI.
Benito Pérez Galdós: un monumento "nacional" liberal
Authors: Rubio Jiménez Jesús
Published: March 2023

Pérez Galdós fue uno de los referentes intelectuales imprescindibles del liberalismo español. En los últimos meses de su vida se mantenía viva su consideración como escritor nacional y gran patriarca de las letras españolas. En este ensayo se analizan textos e imágenes de dos episodios, que permiten calibrar el alcance y significación de su liderazgo social: la erección del monumento dedicado al escritor en el Retiro madrileño (1918-1919) y el homenaje que le rindieron la prensa liberal y el pueblo de Madrid cuando falleció el día 4 de enero de 1920.

La relación entre producción poética y guerra es siempre compleja. ¿Es posible hacer algo más que himnos o canciones? El artículo analiza con detalle uno de los poemas de Rafael Alberti escrito durante la Guerra Civil española. Dejando claro que el sujeto es el resultado de un conglomerado de influencias sociales y económicas, mediatizado por ellas y de las que no puede escapar, se plantea también que un poema desde dentro de la guerra no puede ser más que un poema a vida o muerte. Y desde este supuesto se lleva a cabo el análisis de «Niebla».Palabras clave: Poesía, Guerra Civil Española, Rafael Alberti.Abstract: The relationship between poetry and war is always a complex issue. Is it possible to make anything else than hymns or songs? This article is a detailed analysis of a Rafael Alberti’s poem composed during the Spanish Civil Word. As it is obvious, the subject can’t avoid all the influences of his social surrounding, and any poem written in the middle of the war is a poem in the border of life or death. From this suppose the author analyses «Niebla».Key words: Poetry, Spanish, Civil World, Rafael Alberti
El republicanismo de Antonio Machado hasta 1936
Authors: Fuentes Víctor
Published: March 2023

Aunque es mucho lo que se ha escrito sobre el republicanismo de Machado, este artículo tratará de relacionar este tema con su vida y obra. Se aspira así a destacar facetas menos sabidas por la mayoría de sus lectores y aún de la crítica al respecto. Analizaré las ideas forjadas por Machado en sus años de lectura y reflexión filosófica para demostrar cómo entendió, bien temprano, la crisis del sujeto y la noción de otredad, a la vez que se adentró en el conocimiento del alma popular. Mientras Machado toma distancia respecto a la llamada «Generación del 98», empieza su marcha al pueblo y desarrolla sus ideas acerca de la literatura política y popular. Con la proclamación de la Segunda República, Machado se convirtió en un intelectual público y participó activamente en las organizaciones republicanas asumiendo incluso cargos relevantes (aunque más honoríficos que orgánicos).Palabras clave: Machado, crisis del sujeto, otredad, literatura política, republicanismo.Abstract: Despite the many words written on Machado’s republicanism, this article will try to relate this issue to the biography and the works by Antonio Machado. Necessarily, I will repeat some ideas well-known, but I will also intend to shed light on the least known by many readers. I will analyze the ideas that Machado forges during his years of readings and philosophical reflection in order to demonstrate how he understood, so early, the crisis of the subject and the notion of otherness, as well as he went deeper into the knowledge of the «soul of the country». Whereas Machado distanced himself from the so-called «Generación del 98», he began this approach to the people and he develop his ideas about the political and popular literature. With the proclamation of the Second Spanish Republic, Machado turned into a public intellectual and he was active in republican organizations taking up relevant positions (even if they were more honorifics than organics).Key words: Machado, crisis of the subject, otherness, political literature, republicanism.

Published: March 2023

The biomass resources oil palm empty fruit bunch (EFB) and sugarcane bagasse, which are residues from the palm oil and sugar industries, continue to be investigated for more applications. With increasing concern for the environment, cleaner production has been a worldwide aim of researchers. In this study, thermomechanical pulp (TMP) from EFB and sugarcane bagasse was prepared with disc refining after steam pretreatment of the raw materials. Afterwards, refining and handsheet properties of TMP using various percentages of unbleached soda bagasse pulp (USBP) were studied. Fiber characterizations and handsheet properties showed that pulp of acceptable quality was obtained via thermomechanical pulping. Moreover, energy consumption during PFI refining of EFB TMP was higher than that of bagasse TMP. Physical properties were further enhanced through introduction of USBP. The results firmly support the feasibility of cleaner thermomechanical pulping of EFB and sugarcane bagasse.
Effects of ultraviolet aging on properties of wood flour–poly(lactic acid) 3D printing filaments
Authors: Lin Wenshu , Xie Guangqiang , Qiu Zhaowen
Published: March 2023

An ultraviolet (UV) aging test chamber was used to analyze the aging behaviors of wood flour-poly (lactic acid) (PLA) 3D printing filaments under different temperatures. The materials were granulated using a twin-screw extruder, and the filaments were prepared using a single-screw extruder. The aging resistance was determined by comparing the color, tensile strength, scanning electron micrographs, and water absorption rate of the filaments before and after being processed. The aging behaviors tended to be stable when tested at 40 °C for 80 h, or 50 °C for 60 h, or 60 °C for 40 h. At this status, the tensile strength of the filaments was reduced by 44% compared to the originals; the internal structure of the filaments was severely damaged from the SEM images, and obvious porosities can be identified. The water absorption rate was greatly improved. The chromatic degradation (△E*) increased to 10.8 when tested at 40 °C, while this value increased to 10.9 at 50 °C and 10.8 at 60 °C. Therefore, the increase of aging temperature accelerated the UV aging process. It is recommended to add some ultraviolet absorbent into the filaments in order to improve the UV resistance of the materials.
Application of biochar to alleviate effects of allelopathic chemicals on seed germination and seedling growth
Authors: Alshahrani Thobayet Safar , Suansa Nurul Iman
Published: March 2023

Allelochemicals are generally harmful to plant species during one or more of the regeneration phases. This study investigated the influence of biochar in mitigating allelopathic effects of Eucalyptus camaldulensis in plants (Acacia gerrardii and Acacia ampliceps). The seed germination was relatively delayed by dried leaf extract (DLE) on the first day. Both DLE and date palm biochar (DPB) relatively decreased radicle hypocotyl development of both the target species (when compared with the control). In the seedling growth trial, most of the parameters were suppressed by either DLE or DPB. The results revealed that the inhibitory effects of DLE was less pronounced in the case of seed germination when compared with seedling growth. Moreover, any DLE treatments that were mixed with DPB allowed the suppressed plants to develop well. This effect was indicated by the positive value of relative allelopathic effect (RAE). The relative growth rates of seedling height (RGRH) varied for the different treatment combinations. Most of the treatment combinations resulted in a higher RGRH in test cases than in the control. This study provides meaningful results that support the hypothesis that biochar can be used as an absorptive substance in the immobilization of allelopathic chemicals.

Authors: Zhang Jinchao , Wu Chaojun , Yu Dongmei , Zhu Yachong
Published: March 2023

The selective removal of lignin can be a profitable value-added utilization for the pre-hydrolysis liquor (PHL) produced during kraft-based dissolving pulp production. In this work, the soluble lignin was removed from PHL using CaCl2, Al2(SO4)3, cationic polyacrylamide (CPAM), and a CPAM/Al2(SO4)3 dual-system treatment. The results of zeta potential recording revealed that 8.86% of soluble lignin was removed by CaCl2 treatment through charge neutralization and adsorption, and 13.1% soluble lignin was removed by CPAM through charge neutralization and flocculation bridging. The optimal dosages of CaCl2, CPAM, Al2(SO4)3, and CPAM/Al2(SO4)3 dual-system treatments were 2.0 wt%, 30 ppm, 300 ppm, and 60/300 ppm respectively, at which the soluble lignin removals were 8.09%, 9.24%, 18.3%, and 25.0%, respectively. Additionally, the total sugar loss by the CPAM/Al2(SO4)3 dual-system treatment was higher than that by other individual systems; however, the soluble lignin selective removal by the CaCl2 treatment was the highest, at over 80%.
Micro image classification of 19 high-value hardwood species based on texture feature fusion

Published: March 2023

For classification of wood species with similar microstructure, 19 high-value hardwood species of Papilionaceae, Ebenaceae, and Caesalpiniaceae were used as experimental objects. Images of transverse sections, radial sections, and tangential sections were collected by Micro CT. Local binary patterns (LBP) are often used for feature extraction. LBP deformed forms such as uniform LBP, rotation-invariant LBP, and rotation-invariant uniform LBP were fused with Gray-Level Co-Occurrence Matrix (GLCM) to form three fusion features. The fusion features were combined with support vector machine (SVM) or BP neural network to realize wood classification. The texture feature fusion method was found to be better than the single feature classification. Among them, the effect of uniform LBP and GLCM fusion was the best, and the classification accuracy combined with SVM was the highest. The evaluation of the classification of 19 kinds of hardwood mainly depended on transverse sections, and its accuracy was higher than that of the radial and tangential sections. Therefore, the classification results of transverse sections should be taken as the main evaluation basis for the classification of the 19 high-value hardwood species.
Census books of 1701–1703 as a source for the study of female monasteries of the Russian State
Authors: Shamina Irina
Published: March 2023

The history of Russian female monasticism is one of the little-studied topics. One of the main sources that allows us to characterize the monasteries of the late XVII – early XVIII centuries are the census books that were compiled as part of the initial stage of the church reform of Peter I. The census books of 1701-1703 are a multifaceted source. A large place in them is occupied by information about monastic temples and their interior decoration, about the treasury, where monastic documents were kept, libraries, economic activities, land holdings, etc. The study showed that the census books for the study of nunneries are a very informative source. On their basis, it is possible to establish the number of women's monasteries. They contain information about the management of monasteries, about the social status of nuns, their daily life, as well as about the income and financing of monasteries by the state. The materials of the description to one degree or another reflect the church transformations of Peter I carried out in the country in 1701-1703, which had a significant impact on the life and way of life of the nuns. This makes the census books a very promising source for studying the history of women's monasteries in Russia at the turn of the XVII–XVIII centuries.
Nobility of Kazan province of the 2nd half of the 18th century: ranks’ makeup and the number of serfs owned
Authors: Feofanov Alexander
Published: March 2023

The study is based on the materials preserved in the Fund 1355 (Economic Notes to the plans of the General Land Survey of the Russian Empire) of the Russian State Archive of Ancient Acts (RGADA). These economic notes, compiled at the turn of the XVIII-XIX centuries, indicate the rank of landowner, and the number of souls according to the 5th revision. Service records (form lists) from the Fund 1349 of the Russian State Historical Archive (RGIA), years 1798-1802, had been used for the description of Kazan bureaucracy. At the end of the XVIII century, according to the 5th revision in the Kazan province, there were 1010 landowners, of which 465 were women. Most of the landowners were retired, this shows that the nobles actively used their right not to serve, granted to them by the Manifesto of 1762. Of those who served, a little more than half were in the state service, or served in garrisons, which they entered after active military (army or guards) service. Most of them retired in officer ranks. No more than 7.5 percent of nobles had general ranks of 1-5 classes. More than 20 percent of Kazan nobles owned at least a hundred souls, large landowners owning more than 500 souls compiled 5 percent. Many landowners (more than 19 percent) owned estates in other regions of the Russian Empire, most of all such estates were in the Nizhny Novgorod province. There were about 3 percent of titled nobles. The number of Kazan nobles educated at the Kazan gymnasium varies from 6 percent (in 1781) to 4 percent at the end of the 18th century. Moreover, this number of students of the Kazan gymnasium exceeds the total number of pupils of other educational institutions (primarily cadet corps). Median numbers show that nobles entered the service on average at the age of 14 (most - from 12 to 16), and received the first class rank at 21, more than half - from 18 to 24 years old. The vast majority of nobles entered military service, and then retired; a small part continued to serve in the civil service.

ncs-Si–SiO x :Sm structures formed by high-temperature air annealing of the SiO x films doped with samarium during thermal co-evaporation in vacuum of silicon monoxide and metallic Sm was studied. By measuring the spectra of photoluminescence (PL), it has been shown that doping of SiO x films with Sm stimulates their decomposition into Si and SiO 2 , and also reduces the transition temperature of silicon nanoparticle from the amorphous state to the crystalline one. With an increase in the impurity content up to 2 wt.%, along with the ncs-Si luminescence, the PL spectrum exhibits emission bands of Sm 3+ and Sm 2+ ions, which do not appear at a lower Sm concentration. The presence of silicon nanocrystals in SiO x films doped with Sm and annealed at 970 °C in air has been confirmed using Raman scattering spectra. A possible mechanism for interaction of samarium ions with the SiO x matrix and ncs-Si has been discussed.
Robust correlation scaled principal component regression
Authors: TAHİR Aiman , ILYAS Dr. Maryam
Published: March 2023

In multiple regression, different techniques are available to deal with the situation where the predictors are large in number, and multicollinearity exists among them. Some of these approaches rely on correlation and others depend on principal components. To cope with the influential observations (outliers, leverage, or both) in the data matrix for regression purposes, two techniques are proposed in this paper. These are Robust Correlation Based Regression (RCBR) and Robust Correlation Scaled Principal Component Regression (RCSPCR). These proposed methods are compared with the existing methods, i.e., traditional Principal Component Regression (PCR), Correlation Scaled Principal Component Regression (CSPCR), and Correlation Based Regression (CBR). Also, Macro (Missingness and cellwise and row-wise outliers) RCSPCR is proposed to cope with the problem of multicollinearity, the high dimensionality of the dataset, outliers, and missing observations simultaneously. The proposed techniques are assessed by considering several simulated scenarios with appropriate levels of contamination. The results indicate that the suggested techniques seem to be more reliable for analyzing the data with missingness and outlyingness. Additionally, real-life data applications are also used to illustrate the performance of the proposed methods.

A method of sequential injection determination of tricyclic antidepressants (amitriptyline, desipramine, imipramine) using amperometric immunosensors based on screen-printed graphite electrodes modified by carbon nanomaterials (carbon nanotubes, graphene oxide or fullerene) in combination with hexarhenium chalcogenide clusters is proposed. Sequential injection analysis was performed at a sweep rate of 10 mV/s; the flow rate (supporting electrolyte – phosphate buffer solution with pH 7.0) was also varied from 20 to 40 µl/s. Composition of the modifier affects the analytical capability of immunosensors. Screening of various types of modifiers showed that the immunosensor based on graphene oxide and cyanide complexes of rhenium chalcogenide clusters exhibited the highest sensitivity of 23.9±0.9 with a range of working concentrations of 1·10–10–1·10–5 M, and even wider range of detectable concentrations, 1·10–10–1·10–4 M was observed for the immunosensor based on fullerene and cyanide complexes of rhenium chalcogenide clusters. The lowest limit of the determined contents was (4–7)·10–11 M. Relative standard deviation of repeatability (Sr) did not exceed 0.046. The results obtained show that the proposed immunosensors can be used in sequential injection determination of trace amounts of medicinal compounds (antidepressants) in biomedical objects.

Published: March 2023

In the era of digitalization and pandemic, freelancing is becoming an increasingly common lifestyle and way of earning money. At the same time, journalism is one of the most popular professions for freelance work. In the following, we analyzed the history of the beginning of the career and professional development of 204 freelance journalists in order to compile a socio­demographic portrait of the average freelance journalist in modern Russia. The results obtained in the course of the research can be useful for the subsequent regulation of this sphere at the level of the state and media editorial offices: this process is already beginning and will inevitably continue due to the rapid popularization of remote work and freelancing. However, for successful development of media freelancing, the question should be answered: who is a modern media freelancer?
Anthropology of the Thaw. Friendship Stories of the Ural And Moscow Artists
Authors:   Ernst Neizvestny Art Museum, Fadeev Lev A.
Published: March 2023

The article represents the anthropological aspect of friendship between the famous Ural and Moscow artists of the sixties. The study is focused on the personality of the sculptor Ernst Neizvestny, who was born in Sverdlovsk, studied and worked in Moscow (and later in Europe and the USA). Ernst Neizvestny was the link between the artistic realities of the Urals and the capital city. When visiting his parents in his hometown, he met with the Ural artists, who in turn often visited the Neizvestny’s Moscow studios, and after the collapse of the USSR, they were keeping in touch while being abroad. In the study, based on a range of personal sources, for example interviews and publications, the theme of the Thaw Generation, friendship between artists is considered not only in the social context of mutual support, but also as a special phenomenon that brings together the characters, styles and symbols of creativity. The study proves that through the exchange of ideas and subjective perceptions the artistic culture of that time, deviating from the socialist realistic canons, but forced to be in the ideological field of Soviet culture, developed.
Felsefede Sistemleştirme Dayatması Karşısında Heidegger’e Göre Karar’ın Değeri ve Kurtuluş’a Katkısı
Authors: MIZRAK Seyhan
Published: March 2023

Heidegger’in geç dönem felsefesi hep merak edilmiştir. Bu merakın altında Kurtarıcı Son Tanrı Fügesi bulunmaktadır. Bu yüzden kendisi, Olagelme’den (VomEreignis) Felsefe’ye katkı sunmak ister ve bir başyapıt kaleme alır. Söz konusu makalemiz, zikredilen meraktan felsefi kaygıya geçiş sıçramasıyla problemleştirmenin araştırma konusuna taşınmasının bir gereği olarak hazırlanmıştır ve Felsefe’yeOlagelme’den Katkılar kitabından beslenmektedir. Sistem ve Karar başlıklarının iddiaları ve birbirinin yerine geçme durumları irdelenmektedir. Modern çağda sistem ve sistemlerin yaygınlaşmasında, Bilimler’deki kesinlik düşüncesinin ve hakikatin önüne geçen yöntem algısının etkisi büyüktür. Bilim’in daha fazla kesinlik kazanması, O’nun (dasSeyn’in) terk edişi ve edilişinin pekiştirilmesi yüzündendir. Sistemleştirmeden ve nedensellikle düşünmekten ziyade Heidegger’de nelere Karar denildiği ve neden böyle bir ayrıma gidildiği araştırılmıştır. On bir Karar’ın değeri, karşılaştırma hâlinde seçikleştirilerek ortaya konulmaktadır. Heidegger’e göre felsefede revizyon yapılmalıdır. Zira felsefede sistemler dönemi bitmiştir ve yetkiden geçen Karar/lar dönemi yeniden hatırlanmalı veya hatırlatılmalıdır. En son kertede acziyet ve tehlike, karar ânıdır. Hölderlinci anlayışa göre nerede bir tehlike varsa orada sağaltıcı güç bulunur. Sağaltıcı gücün yani kurtuluşun olması için tehlike maksimum düzeye çıkmalıdır. Böylece bunalım dönemlerinde felsefe umut idesini yeşertebilecektir. Umut idesi felsefenin temellendirdiği sorularla kilit taşı sorularını içeriden aştığı Öteki Başlangıç’la imkân dairesine girecektir. Heidegger burada Karar kavramından yaratmayı ve temellendirmeyi kastetmektedir. Ancak bu yaratma, yaşantı kavramıyla ve makineleşmeyle yozlaşmış çağımızın tekrardan felsefî temellendirilmesini ve yorumlanmasını gerektirecektir. Karar, O’nun kendi kendinin zemininin burada olduğu mahaldir ve O’nun hakikati Son Tanrı Fügesi’ndefigürleşir. Son Tanrı, insanlığın kurtuluşudur. Zaten Heidegger’in son mülakatında söylediği de budur. Karar, düşünme etkinliğinin de merkezinde durmaktadır. Bu görev, nadir sayıdaki gelecekten gelecek Düşünür-Eğitmenler’in işidir. Gelassenheit metninde Heidegger; Bilim Adamı, Âlim ve Eğitmen diyaloğunda Nadirler’in karar ânının kilit taşı ve yol açıcıları olduklarını vurgulamaktadır. Neticede Karar, olağanüstü manada anlaşılır. Kararın/kararların fevkaladeliği, Kurtarıcı Son Tanrı fügesinin yolunu açmaktadır. Heidegger’de kurtuluş aslında Meister Eckhart’ın Salıverme basamaklandırmasıdır.
UM ESTUDO SOBRE NOMOFOBIA E CRENÇAS DE AUTOEFICÁCIA ACADÊMICA EM ESTUDANTES UNIVERSITÁRIOS
Authors: Machado Débora Vieira , Eisenberg Zena
Published: March 2023

O objetivo deste estudo é compreender se há relação da nomofobia com as crenças de autoeficácia em estudantes universitários. Foi utilizado o método misto e o estudo foi dividido em duas etapas. Na primeira etapa, por meio de um formulário on-line, foram aplicados dois instrumentos (Escala de Autoeficácia na Formação Superior e Questionário de Nomofobia). Na segunda etapa, foram realizadas entrevistas semiestruturadas. De maneira geral, os dados apontam que quanto maior a percepção de crenças de autoeficácia acadêmicas dos estudantes universitários, maior o nível de nomofobia. Essa relação pode ser explicada com o fato de os alunos se sentirem mais capazes de realizar as suas tarefas acadêmicas quando utilizam as tecnologias digitais como suporte, no entanto, o uso excessivo traz consigo prejuízos à aprendizagem. Concluímos que, a partir dos resultados e reflexões apresentadas, sejam possíveis outros entendimentos sobre a percepção que os estudantes têm sobre a sua capacidade de executar as tarefas acadêmicas fazendo uso das tecnologias digitais. Compreendemos que a alta percepção de crenças de autoeficácia não podem ser consideradas uma causa de nomofobia. Contudo, pensamos que este resultado pode contribuir para que sejam feitas conscientização sobre os prejuízos do uso excessivo das tecnologias digitais no processo de aprendizagem.

El liderazgo directivo y el clima organizacional son esenciales para el correcto desempeño de los docentes escolares. Intrínsecamente, este análisis busca identificar la influencia del liderazgo directivo y el clima organizacional en los docentes mediante una revisión sistemática. Para ello, se realizó una selección de publicaciones internacionales y nacionales sobre el tema estudiado y se recopilaron 25 artículos que cumplían los criterios de inclusión. Se infiere que la construcción de un clima adecuado es un fragmento trascendental de la ocupación de liderazgo de los dirigentes educativos, y una gran cantidad de estudios contemporáneos se centralizan en mostrar cómo influye los estilos de liderazgo transformacional en los docentes. Se deduce que el liderazgo de la autoridad de la escuela tiene una influencia positiva en el progreso del clima organizacional observado por los pedagogos; conjuntamente, la motivación emergió como el vehículo mediante el cual se influye en el clima escolar. Además, los saberes examinados concuerdan en que el líder escolar idóneo debe instaurar una distribución que genere fervor y suscite la colaboración de todos los integrantes de la institución.
Experimental characterisation of flexural bond behaviour in brick masonry
Authors: Gaggero Maria B. , Esposito Rita
Published: March 2023

The brick-to-mortar bond often represents the weakest link leading to cracking and failure of masonry structures. For this reason, the in-situ characterization of masonry’s flexural bond behaviour (here defined as flexural bond strength and flexural bond fracture energy), is essential for the assessment of existing buildings. Among masonry bond properties, the flexural bond strength is commonly determined on-site, given the minimal invasiveness of the so-called bond wrench test. However, often the reliability of the results is questioned inputting their large variability to the operator. The present study discharges this assumption by comparing the accuracy of various testing set-ups (manually-operated vs computer-controlled set-ups). Additionally, the influence of the specimen’s type (with/without head joints and couplets vs wallet) on the flexural bond strength assessment is studied providing preliminary correlation factors that can be of help for the in-situ measurement on single-wythe masonry. In addition, to obtain a complete description of the bond behaviour, a new test set-up able to determine the post-peak response is presented. Considerations regarding the dissipated bond fracture energy and its relation to the tensile fracture energy are provided with the support of literature data.

Breast cancer is a genetic disease caused by the accumulation of mutations in neoplastic cells and is responsible for the highest morbidity and mortality. In this study, blood serum samples from 45 breast cancer patients and 32 healthy individuals (control group) were used. The amounts of vitamins (A, E, β-carotene, C, B1, B2, B3, B5, B6, B9 and B12), glutathione (GSH, GSSG) stress biomarkers (4-HNE, MDA) were determined by HPLC. A significant difference was found between the breast cancer patients and the control group in terms of age and body mass index (BMI) (p
Factores de innovación en sistemas agroalimentarios con Denominación de Origen: el caso del chile Yahualica en México
Authors: Martínez-Salvador Laura Elena
Published: March 2023

Los sistemas agroalimentarios localizados (SIAL) que se entretejen alrededor de bienes agroalimentarios vinculados a la calidad de origen como las denominaciones de origen (D.O) requieren de generar procesos de innovación para tender hacia un sendero de sostenibilidad. Esta innovación depende de múltiples factores, por lo que el objetivo de este trabajo es analizar la forma en como una serie de factores de influencia (input) influyen en el comportamiento innovador (output) de productores en SIALes bajo la D.O, especialmente de un bien con gran arraigo a la cultura alimentaria en México: el chile Yahualica. Esto, a partir de una metodología cualitativa de estudio de caso, y cuantitativa como la encuesta y el análisis estadístico. Se concluye que el factor ‘sofisticación de negocio’, que identifica la articulación entre actores para el aprendizaje, se posiciona como el elemento de mayor impacto sobre el comportamiento innovador de los productores. Este comportamiento innovador se traduce en una mayor tendencia a implementar eco-innovaciones e innovaciones de comercialización. El caso de la innovación en el SIAL bajo la D.O chile Yahualica puede mostrar el camino hacia una integración de tecnologías y una conservación de las identidades territoriales.
Naturaleza ex situ: arcas de la biodiversidad
Authors: Zavaro Pérez Carlos Alberto
Published: March 2023

Conservar la diversidad biológica constituye un tema central en la actualidad, ante el creciente deterioro ambiental, el impacto del cambio climático y los modelos de sociedad basados en una perspectiva extractivista. En ese contexto, muchos zoológicos, jardines botánicos y acuarios históricos han comenzado un proceso de transformación. Convertidos en bioparques, redefinen sus propósitos. El objetivo de este artículo es reflexionar en torno al rol que tiene la definición de las colecciones biológicas en estas instituciones, tanto en el ordenamiento espacial de la exhibición (y, por lo tanto, del diseño del recorrido) como en la delimitación de los objetivos institucionales, que incluyen la implementación de programas de conservación ex-situ, su articulación con los sistemas de áreas protegidas y con el diseño de propuestas educativas que, bajo diversos formatos de la educación ambiental, comprenden el trabajo con escuelas y el público visitante. Con base en una perspectiva conservacionista, que sostiene la necesidad de un modelo sostenible de desarrollo y redistribución de la riqueza, se considera relevante la redefinición del rol de estas instituciones.

Abstract

The conservation of biological diversity is currently a central issue in the face of increasing environmental deterioration, the impact of climate change and the models of society based on an extractivist perspective. In this context, many zoos, botanical gardens and historic aquariums have begun a transformation process to become bio parks, redefining their purposes. The objective of this article is to reflect on the role that the definition of biological collections has in these institutions today, both in the spatial arrangement of the exhibition -and therefore in the design of the tour-, as well as in the delimitation of the institutional objectives that include the implementation of ex-situ conservation programs, their articulation with the systems of protected areas and with the design of educational proposals that, under various formats of environmental education, understand the work with schools and the visiting public. From a conservationist perspective that supports the need for a sustainable model of development and redistribution of wealth, it is relevant to redefine the role of these institutions.
Trayectorias tóxicas: habitar, migrar y asentarse en zonas de sacrificio rurales y urbanas
Authors: Castilla Malena Ines
Published: March 2023

El presente artículo se propone analizar y describir dos escenarios diferentes, pero con devenires similares, donde la población indígena constituye uno de los sectores más afectados. Por un lado, la región chaqueña en el norte de la República Argentina y, por el otro, la Región Metropolitana de Buenos Aires, en el centro neurálgico del país. Estas regiones, a pesar de tener historias productivas diferentes, se encuentran atravesadas por un modelo extractivo que avanza sobre sus territorios y los transforma en zonas de sacrificio. A partir de investigaciones precedentes y de datos primarios obtenidos del trabajo etnográfico, se retoman entrevistas en profundidad, virtuales y telefónicas, situaciones conversacionales, notas de campo, fuentes primarias y secundarias, mapas catastrales, censos poblacionales, entre otros. Desde la perspectiva de la antropología social, se analizan los escenarios de desigualdad socioeconómica y ambiental que se desarrollan en ambas regiones y el impacto que tienen en las poblaciones locales que, en muchos casos, se ven forzadas a migrar y consolidar sus experiencias tóxicas, signadas por escenarios de pobreza, hacinamiento, contaminación, invisibilización y negación.
Representaciones sociales de la movilidad cotidiana: una aproximación desde la sostenibilidad
Authors: Castro-Sánchez Laura-Elena , Delgado Ramos Gian Carlo
Published: March 2023

Ante la creciente movilidad cotidiana global, se observa un predominio de visiones parceladas del conocimiento como respaldo de las políticas para lograr la sostenibilidad de ese fenómeno, las cuales se han enfocado mayormente en aspectos materiales. Este artículo desarrolla una hibridación de las propuestas teóricas en torno a la movilidad cotidiana y la sostenibilidad, desde una mirada inter y transdisciplinaria. Para ello, se hace una revisión de los campos de conocimiento que aportan aproximaciones teóricas y conceptos clave para la construcción de un Índice de Movilidad Cotidiana Sostenible (IMCS) que comprende cuatro dimensiones de análisis: ecología, bienestar, gobernanza y cultura, esta última vista desde las representaciones sociales y como ruta para establecer nexos con la dimensión material de la movilidad cotidiana. A partir de resultados preliminares para el caso del Barrio Antiguo en la ciudad de Monterrey, México, se concluye con una reflexión acerca de la utilidad del IMCS en un contexto latinoamericano cuyas características socioeconómicas, culturales y espaciales hacen de las representaciones sociales un factor clave para explicar diversas dinámicas, retos y potenciales soluciones.
Influence of season and other factors on avian Trypanosoma spp. and microfilarial prevalence in the Lowveld, South Africa

To comprehend the effects of emerging infectious diseases on both human and animal health, it is necessary to understand the ecology of pathogens that have wildlife reservoirs. In this study, we determined the prevalence of the parasites Trypanosoma spp. and filarial nematodes in the bloodstream of birds in and around the Kruger National Park, South Africa, partly to test the hypothesis that season influences parasitaemia. Other factors considered were foraging habits, gregariousness or solitariness, and whether location might facilitate contact between birds and parasite vectors. Microscopy was used to screen stained blood smears prepared from 685 captured birds of 87 species. It was found that 3.9% of the birds were infected with filarial nematodes (as reflected by the presence of microfilariae) and 3.1% with Trypanosoma spp. No cases of coinfection with both types of parasite were encountered. Ground-foraging and solitary birds had the highest parasite prevalences compared to other birds. Infections were recorded throughout the year at all six sites. The respective percentages of birds harbouring the two parasite types in the dry season were the same (both 2.3%), whereas microfilariae dominated in the wet season (6.9%) and the prevalence of Trypanosoma spp. then was 1.4%. These findings represent new knowledge concerning avian haemoparasite prevalence in an Afrotropical setting – something that has so far been poorly studied.
Significance:

The determination by microscopy of the prevalence of microfilariae of filarial nematodes (3.9%) and Trypanosoma (3.1%) in the peripheral blood of 685 birds of 87 species provides new knowledge on birds in Africa.
Unexpectedly, ground-foraging and solitary birds had the highest parasite prevalences.
The possibility of human infection with these two types of avian parasites is considered.

A COVID-19 colocou na agenda pública a necessidade de disseminação de informações confiáveis sobre o cenário epidemiológico da doença nas diversas regiões do mundo. No Brasil, vários gestores assumiram a tarefa de informar a população local sobre a progressão da pandemia em seus municípios. Neste estudo, o objetivo foi refletir sobre a construção/elaboração de boletins/infográficos da COVID-19 e da centralidade do design na disseminação de informações em saúde, analisando, para tal, 133 infográficos sobre os números da doença publicados no Instagram da Fundação Municipal de Saúde de Rio Claro, no interior do estado de São Paulo/Brasil, no período de 30 de março a 31 de julho de 2020. A análise qualitativa realizada a partir da perspectiva multimodal possibilitou identificar que esses foram construídos num processo iterativo, com alterações ao longo do tempo para excluir ou incluir informações à medida que a pandemia se espalhava no município. Os infográficos foram analisados em três dimensões: formato, cores e conteúdo. Concluímos que a sua elaboração foi baseada em conceitos básicos do design relativos à forma e às cores e que nos primeiros cinco meses foram produzidas três versões num processo de refinamento do desenho e das informações até conseguir um formato mais consistente para a comunicação dos dados da pandemia da COVID-19.
