Market efficiency as indicators of fish market along the middle stretch of River Ganga, India
Authors: Shaikh Jahanara , Shrivastava R. S. , Jha Dharmnath , Pandey Amit Ranjan
Published: March 2023

The fish market in the state of Uttar Pradesh, India, is not formally organised. Rather, it permeates from a direct fisher market to a wholesale market. Fish caught from the River Ganga are distributed through many intermediaries and are transported to farther regions like Guwahati and Kolkata in the east. The objective of the study is to assess market efficiency and, with this assessment, make recommendations that can be used to improve the livelihoods of the fishers. We accomplish this by investigating market efficiency indicators including production capacity of the area, Percent Share of Fisher in the Consumer's Money, and price stability of fish markets in different districts (including Bulandshahr, Farrukhabad, Kanpur, Fatehpur, Prayagraj and Varanasi). These are the districts that are located on the bank of the River Ganga in the state of Uttar Pradesh. The study consists of interviews with fishers, wholesalers, vendors, auctioneers, and consumers. The study examines 9 wholesalers, 9 retail markets and 1 direct fisher market. The demographic variables of fish sellers viz. age, education, caste, family size, experience and occupation are also studied. Descriptive statistics and cross-tabulation are used for nominal variables to measure and test conceptions and misconceptions of the fish market. Fish selling is carried out through fish market channels including 220 middlemen, 249 retailers, 48 wholesalers, and 72 auctioneers. Together, these individuals make up the channel structure, channel strategy, and channel performance. The high number of middlemen demonstrates that the market structure is inefficient. Higher Percent Share of Fisher in the Consumer's Money was observed for fishes like Labeo rohita (65.8%), Cirrhinus Mrigala (64%), and Labeo Calbasu (64.3%). The average Percent Share of Fisher in the Consumer's Money is 54% and shows the fishers earn little more than half of the revenue generated. The study shows that high-value fish have less price stability and low-value fish have high price stability across the fish market channel, respectively. Our investigation recommends reducing the number of market channels with the application of modern infrastructure in order to increase the quality of products received by the consumer and to increase fisher share in consumer's money.

The Sundarbans, major marshy land, and brackish water ecosystem of the West Bengal were inhabited by many species of fishes which were the main dependants of the people living there. The present investigation was conducted using a questionnaire survey, participatory rural appraisal, key informant interviews, and focus group discussion and to assess the present state of production of major cultivable species of Sundarbans like mullet, shrimp, tilapia, mud-crabs, giant prawn and Asian seabass. A socioeconomic and technical survey of 45 trained and 45 traditional practitioners of aquaculture were conducted from May 2017 – April 2018. This study and appraisal intended to compare the socioeconomic relationship between traditional fish farmers and trained aquaculturists in Indian Sundarbans. The modern farmers usually practice the farming systems like Jayantirohu cultivation, white shrimp cultivation, genetically improved farmed tilapia, crabs fattening and crab culture; periphyton based giant prawn cultivation and Asian seabass culture with forage feeding with bait fishes. The trained farmers were enriched with much knowledge and information gained from various training, which the traditional farmers were lacking. It was found average benefit-cost ratio for traditional farming and modern farming system of 1:1.89 for traditional fish farmers and 1:3.13 for trained farmers. It was helping the modern practitioners to earn more profit to suffice their family needs as well as they were now accomplishing more safety, security measures for their family, investing more in their aquaculture practices. The yield of fish culture was affected by pond conditions, family labor engagement, and resource endowment of the fisher family. Linkage with formal financial institutions, subsidized input support from the fishery department, and investment in human resource development of farmers might be some point of intervention to boost fish culture in the coastal zone of West Bengal, India.

Neste artigo, analiso a obra O Poço da Solidão (1928), de Radclyffe Hall (1880-1943), a partir de seu contexto de publicação e da construção narrativa da protagonista Stephen em relação à lesbianidade. Levando em consideração que Stephen transgride as imposições dos papéis sexuais da socialização feminina, abordo as teorias desenvolvidas por Simone de Beauvoir (1949) e, posteriormente, Monique Wittig (1980), dentre outras. Ao ter a possibilidade do que Virginia Woolf (1928) caracteriza como “um teto todo seu”, Stephen se destaca enquanto escritora, mas ainda assim passa por conflitos acerca de sua sexualidade devido aos discursos conservadores da família, da medicina e da religião, os quais incidem sobre ela e a impedem de ter uma existência lésbica plena.

Authors: Sekaringsih Riswanti Budi , Al-Banna Hasan
Published: March 2023

The objective of this paper is to analyze the debate about cryptocurrency as money from an Islamic point of view. Money in Islam that is based on urf of custom has also some requirements, such as its stability. Some fatwas in Indonesia regarding the legitimacy of cryptocurrency must be evidenced with an empirical-based. The study used 25 cryptocurrency prices and related information. By employing ARCH and GARCH, the study revealed that cryptocurrency is hugely volatile and, thus, does not fulfill such criterion as money from an Islamic perspective, and is normally used for speculation. Hence, this study suggests that cryptocurrency is still reluctant to be used for a transaction.

O presente trabalho apresenta a aplicação da metodologia DMAIC como meio de obtenção de melhoria, resultando na padronização do processo produtivo e reestruturação organizacional do ambiente produtivo. A pesquisa foi realizada através de um estudo de caso, na qual foram realizadas observações e coletados dados no processo atual, sendo assim possível a proposição de melhorias em um comércio alimentício de pequeno porte, localizado no sul de Minas Gerais. Devido a pandemia de COVID-19, a mudança repentina na forma das pessoas consumirem comida foi uma surpresa para os donos de estabelecimentos do ramo da alimentação, pois o serviço de delivery passou a ter enorme procura. Sequentemente, o gerenciamento desde o pedido até a entrega passou a apresentar falhas, gerando insatisfação dos consumidores. O método DMAIC foi utilizado como metodologia de análise e solução de falhas para a coordenação das etapas, assim como a utilização de ferramentas da qualidade necessárias em cada uma das fases. Foram aplicadas apenas as quatro primeiras etapas do método (definir, medir, analisar e melhorar), pois até a presente data não foi possível a aplicação do plano de ação.  Ademais, dentre as soluções propostas pelos autores, muitas exigem reformas no ambiente, realocação de postos de trabalho, reformulação dos processos produtivos, treinamento dos funcionários e aquisição de alguns equipamentos.

A new parametrization for ideal classes in rings defined by binary forms, and applications
Authors: Swaminathan Ashvin A.
Published: March 2023

We give a parametrization of square roots of the ideal
class of the inverse different of rings defined by binary forms in terms of the orbits of a coregular representation. This parametrization, which can be construed as a new integral model of a “higher composition law” discovered by Bhargava and generalized by Wood, was the missing ingredient needed to solve a range of previously intractable open problems concerning distributions of class groups, Selmer groups, and related objects. For instance, in this paper, we apply the parametrization to bound the average size of the 2-class group in families of number fields defined by binary n-ic forms, where

n

{n\geq 3}

is an arbitrary integer, odd or even; in the paper [A.

Bhargava, A. Shankar and A. Swaminathan,

preprint 2021], joint with Bhargava and Shankar, we applied it to bound the second moment of the size of the 2-Selmer group of elliptic curves.
Scalar curvature and deformations of complex structures
Authors: Scarpa Carlo
Published: March 2023

We study a system of equations on a compact complex manifold, that couples the scalar curvature of a Kähler metric with a spectral function of a first-order deformation of the complex structure. The system comes from an infinite-dimensional Kähler reduction, which is a hyperkähler reduction for a particular choice of the spectral function. The main tool for studying the system is a flat connection on the space of first-order deformations of the complex structure, that allows to obtain a formal complexification of the moment map equations. Using this connection, we describe a variational characterization of the equations, a Futaki invariant for the system, and a generalization of K-stability that is conjectured to characterize the existence of solutions.
Vertical photon sorting by stacking silicon and germanium nanopillars for broadband absorbers
Authors: Xu Rongyang , Morimoto Takumi , Takahara Junichi
Published: March 2023

Perfect absorbers based on all-dielectric metasurfaces exhibit great potential in photodetection, photovoltaics, and imaging applications. This study proposes and demonstrates an all-dielectric broadband absorber comprising subwavelength-thick nanopillar Mie resonators in the visible light range. This nanopillar functions as a perfect absorber based on degenerate critical coupling with a characteristic “degenerate critical length.” At this length, the nanopillars are capable of achieving perfect absorption. Beyond this length, the peak of perfect absorption is not affected with further increases in the length of the nanopillars. Hence, this study realizes broadband absorption via the stacking of amorphous silicon and germanium nanopillars with the same width at different peak absorption wavelengths. The absorption spectra are almost independent of the order of the stacked structures; hence, the stacked nanopillars in the specific stacking order can behave as a vertical photon sorter, sorting photons based on the wavelength. This study provides a systematic route to the realization of broadband absorbers with vertical photon sorting capability via the vertical stacking of nanopillars.
Gott im Selfie
Authors: Tetzlaff Karl
Published: March 2023

Am Beispiel der häufig zum Symptom eines narzisstischen Zeitalters erklärten Selfie-Praxis wird in diesem Text das Verhältnis von Selbstdarstellung und Verkündigung bedacht. Das in den Sozialen Medien verbreitete Phänomen, sich selbst zum Bild zu machen und anderen Bilder von sich selbst zu präsentieren, tritt dabei als ein religiös grundiertes Unterfangen vor Augen. Eine Sehnsucht nach unvergänglicher Gegenwart lässt sich in der Selfie-Praxis ebenso artikuliert finden wie ein Bewusstsein für die undarstellbare Dimension des individuellen Selbst. Beide Aspekten werden zudem als Versuch eines produktiven Umgangs mit herausfordernden Entwicklungen der Moderne verstanden: mit der durch den sozialen Beschleunigungsdruck hervorgerufenen Gegenwartsschrumpfung auf der einen und dem Zwang zur digitalen Selbstpräsentation auf der anderen Seite. Mithin lässt sich das im Selfie zum Ausdruck kommende Bewusstsein auf die Rede von Gott beziehen: auf Gott als Korrelat jener Sehnsucht nach unvergänglicher Gegenwart und als Inbegriff einer dem menschlichen Selbst unsichtbar eingeschriebenen Lebendigkeit. In dieser ihm innewohnenden Verweisstruktur lässt sich das Selfie selbst als verkündigungsförmig ansehen, was den auch in der Theologie verbreiteten Narzissmusvorwurf gegenüber religiösen Selbstdarstellungspraktiken nicht nur in der Predigtarbeit entkräften sollte.

Very preterm infants show low levels of insulin-like growth factor-1 (IGF-1), which is associated with postnatal growth restriction and poor neurologic outcomes. It remains unknown whether supplemental IGF-1 may stimulate neurodevelopment in preterm neonates. Using cesarean-delivered preterm pigs as a model of preterm infants, we investigated the effects of supplemental IGF-1 on motor function and on regional and cellular brain development. Pigs were treated with 2.25 mg/kg/d recombinant human IGF-1/IGF binding protein-3 complex from birth until day 5 or 9 before the collection of brain samples for quantitative immunohistochemistry (IHC), RNA sequencing, and quantitative PCR analyses. Brain protein synthesis was measured usingin vivolabeling with [2H5] phenylalanine. We showed that the IGF-1 receptor was widely distributed in the brain and largely coexisted with immature neurons. Region-specific quantification of IHC labeling showed that IGF-1 treatment promoted neuronal differentiation, increased subcortical myelination, and attenuated synaptogenesis in a region-dependent and time-dependent manner. The expression levels of genes involved in neuronal and oligodendrocyte maturation, and angiogenic and transport functions were altered, reflecting enhanced brain maturation in response to IGF-1 treatment. Cerebellar protein synthesis was increased by 19% at day 5 and 14% at day 9 after IGF-1 treatment. Treatment had no effect on Iba1+microglia or regional brain weights and did not affect motor development or the expression of genes related to IGF-1 signaling. In conclusion, the data show that supplemental IGF-1 promotes brain maturation in newborn preterm pigs. The results provide further support for IGF-1 supplementation therapy in the early postnatal period in preterm infants.
KNO1‐mediated autophagic degradation of the Bloom syndrome complex component RMI1 promotes homologous recombination
Authors: Chen Poyu , De Winne Nancy , De Jaeger Geert , Ito Masaki , Heese Maren , Schnittger Arp
Published: March 2023

Homologous recombination (HR) is a key DNA damage repair pathway that is tightly adjusted to the state of a cell. A central regulator of homologous recombination is the conserved helicase‐containing Bloom syndrome complex, renowned for its crucial role in maintaining genome integrity. Here, we show that in Arabidopsis thaliana, Bloom complex activity is controlled by selective autophagy. We find that the recently identified DNA damage regulator KNO1 facilitates K63‐linked ubiquitination of RMI1, a structural component of the complex, thereby triggering RMI1 autophagic degradation and resulting in increased homologous recombination. Conversely, reduced autophagic activity makes plants hypersensitive to DNA damage. KNO1 itself is also controlled at the level of proteolysis, in this case mediated by the ubiquitin–proteasome system, becoming stabilized upon DNA damage via two redundantly acting deubiquitinases, UBP12 and UBP13. These findings uncover a regulatory cascade of selective and interconnected protein degradation steps resulting in a fine‐tuned HR response upon DNA damage.

Objective

The transcriptional landscape of Klinefelter syndromeduring early embryogenesis remains elusive. This study aimed to evaluate the impact of X chromosome overdosage in 47,XXY males induced pluripotent stem cells (iPSCs) obtained from patients with different genomic backgrounds and ethnicities.

Design and method

We derived and characterized 15 iPSC lines from four Saudi 47,XXY KS patients and one Saudi 46,XY male. We performed a comparative transcriptional analysis using the Saudi KS-iPSCs and a cohort of European and North American KS-iPSCs.

Results

We identified a panel of X-linked and autosomal genes commonly dysregulated in Saudi and European/North American KS-iPSCs vs 46,XY controls. Our findings demonstrate that seven PAR1 and nine non-PAR escape genes are consistently dysregulated and mostly display comparable transcriptional levels in both groups. Finally, we focused on genes commonly dysregulated in both iPSC cohorts and identified several gene-ontology categories highly relevant to KS physiopathology, including aberrant cardiac muscle contractility, skeletal muscle defects, abnormal synaptic transmission, and behavioral alterations.

Conclusions

Our results indicate that a transcriptomic signature of X chromosome overdosage in KS is potentially attributable to a subset of X-linked genes sensitive to sex chromosome dosage and escaping X inactivation, regardless of the geographical area of origin, ethnicity, and genetic makeup.

Published: March 2023

The current-voltage characteristics of a thin long platinum wire in air with acetone or ethanol small admixtures were obtained. Using the quadratic dependence of platinum resistance on temperature, the temperature-current dependences for the wire were calculated. At concentrations of combustible gas vapors above a certain value, these dependences show a hysteresis character. Using the assumption of acetone and ethanol complete oxidation on platinum, as a catalyst, and the first order of the oxidation reaction, temperature-current dependences was analysised. The temperature difference between the high and low-temperature stationary regimes of catalytic oxidation on the wire makes it possible to estimate the admixture concentration. As a result, the experimental dependence of the critical current value by catalytic ignition and extinction gas mixture on platinum on the admixture concentration was constructed. With its analytical description, it is possible to fairly accurately estimate the apparent values ​​of the activation energy and the pre-exponential multiplier for the oxidation reaction in a wide temperature range. A method of determining the kinetic parameters for the oxidation reaction based on the experimentally found parameters of degeneracy critical conditions is proposed.

Published: March 2023

In order to optimize its production technology, response surface methodology (RSM) was used to optimize the hot-pressing process during the preparation of chitosan-modified starch adhesive film. Ranges of hot-pressing temperature, hot-pressing time, and adhesive consumption were selected based on single-factor tests. A quadratic regression model of the bonding strength was obtained by fitting the response value of the bonding strength of the plywood. The results showed that the adhesive consumption and the hot-pressing temperature had a significant effect on the bonding strength of the adhesive. Also, the interaction between the temperature, time, and adhesive consumption were significant. The optimum hot-pressing process parameters for chitosan-modified starch adhesive film were a hot-pressing temperature of 145.2 °C, a hot-pressing time of 182.7 s, and an adhesive consumption of 239.3 g/m2. The predicted values of the quadratic regression model fit well with the actual values of the stability test.
Effects of peracetic acid and hydrogen peroxide concentration on kraft lignin degradation at room temperature

Published: March 2023

Degradation characteristics of kraft lignin were investigated during peracetic acid (PAA) treatment at room temperature. PAA was prepared by direct mixing of acetic acid (AA) and hydrogen peroxide (HP) at different ratios. At a ratio of AA to HP of 1:1.5 (v/v), undissolved lignin content was the lowest (34.7%). Lignin-derived compounds that were produced from the initial lignin after PAA treatment were detected in the liquid fraction (EA extracts) in small quantities (< below 0.1% of initial lignin), while their species were different depending on mix ratio. It was found that degradation behavior depends on not only PAA, but also HP concentrations. Meanwhile, the lignin-derived products of EA extracts in liquid fractions showed decreased molecular weight and polydispersity compared with the initial lignin. As reaction severity increased, amounts of low-molecular weight lignin in liquid fractions increased. At room temperature, different lignin degradation behavior can be induced by controlling the mix ratio of AA and HP.

Published: March 2023

The accurate measurement of wood dielectric properties and their relationship with many influencing factors are not only necessary for the study of other relevant wood properties, but also improve the wood dielectric moisture content detection method. In this study, the relationships between dielectric properties and frequency, as well as between moisture content and texture direction were analyzed. The results showed that the effect of the moisture content on the dielectric constant is significant. With increasing moisture content, the dielectric constant increased exponentially below the fiber saturation point. The effect of texture direction slightly exceeded that of the radial direction, and the change rate of the tangential direction above the fiber saturation point was higher than that of the radial direction. The relationship between the dielectric constant and frequency was related to the wood moisture content. The dielectric loss was approximately linear with the frequency below the fiber saturation point.
Effect of the dowel length, dowel diameter, and adhesive consumption on bending moment capacity of heat-treated wood dowel joints
Authors: Georgescu Sergiu , Varodi Anca Maria , Răcășan Sergiu , Bedelean Bogdan
Published: March 2023

This study applied response surface methodology for modeling and optimizing heat-treated wood dowel joints, the most used joint in furniture construction. The factors examined were dowel length, dowel diameter, and adhesive consumption. The bending moment capacity of the joints loaded in compression or tension were the responses. The load was applied at a constant speed until a major separation between the two parts occurred. To figure out the bending moment capacity, the ultimate failure loads and the moment arms were obtained during testing the joints. The joints were tested by using a universal testing machine. A two-factor interaction model was established to describe the relationship between the factors and the responses. An analysis of variance was employed to test the significance of the developed mathematical model. The dowel length, dowel diameter, and adhesive consumption had significant effects on the bending moment capacity of the heat-treated dowel joints. The dowel length was the main factor that affected the bending moment capacity of the heat-treated dowel joints.

Waste cotton-derived carbon materials were synthesized using various chemical activators, and their performance as solid acid catalyst supports was studied. The pore surface structures of the carbon materials were quantitatively characterized by surface fractal dimension, and the relationship between pore surface structure and the density of catalyst was also investigated. The pore sizes were grouped into four ranges, including fractal dimensions D1 (0.32 nm to 2.0 nm) and D2 (2.0 nm to 50 nm), as revealed by N2 adsorption and Frenkel-Halsey-Hill fractal theory. In addition, D3 (50 nm to1000 nm) and D4 (1000 nm to 200,000 nm) were revealed by mercury intrusion porosimetry and the Friesen-Mikula fractal theory. The surface fractal dimension D was found to be proportional to the density of SO3H groups from sulfonation at the same carbonization temperature. A larger D value corresponded to the exposure of more active sites, which was more favorable for improving the density of SO3H groups. With the rise of carbonization temperature, the surface fractal dimension also increased. However, the graphitization structure of carbon materials increased with the rise of carbonization temperature, which reduced the active sites of SO3H groups. Finally, the solid acid catalysts prepared via the sulfonation process were used in the esterification reaction of levulinic acid and n-butanol.

The effect of duration of load testing on flexural properties of structural insulated panels was investigated herein. Structural insulated panels were manufactured by a member of the Structural Insulated Panel Association (SIPA) in accordance with International Code Council-Evaluation Service Report 4689. Two panel depths 16.5 cm and 31.1 cm (6.5 in. and 12.25 in.) were tested in short duration 1/3-point bending per American Society for Testing and Materials standards. All structural insulated panels had joints or discontinuities in the foam layer in a location that was subject to shear stress during the bending tests. Failure mode for all panels was horizontal shear within the foam layer. Within each panel depth, no statistically significant differences were detected between the maximum load values before and after creep testing. This finding indicates that the creep test loading was not detrimental to the strength of the structural insulated panels. While the results were not deemed to be statistically different for the Δymax (midspan deflection at Pmax) for the 31.1 cm depth class, they were statistically different from the 16.5 cm depth class. Overall, it appeared that there was minimal effect of the creep test loading on Δymax of the SIPs.

Published: March 2023

The aim of the paper was to identify areas of the compliance management system and assess the advisability of including tax compliance within the compliance management system. The methodology involved an analysis of relevant literature, legal acts and compliance standards. The empirical part presents the results obtained, having analysed areas of compliance management systems in a sample of ten entities listed on the WSE and included in the WIG20 index. The studied entities were found to present a variety of information on compliance management systems without taking into account the area of tax compliance. According to the author, the implementation of a coherent overall compliance management system would bring many benefits regarding the fulfillment of tax obligations – e.g. in the field of Mandatory Disclosure Rules (MDR) or transfer pricing – and also facilitate the conclusion of the so-called cooperation agreements in the area of taxes and the Advanced Pricing Agreements (APA).

Energy efficiency is one of the most important areas that humanity is working on in the world. As in all areas of life, energy used in irrigation has become an important research subject for researchers. In studies performed with performance indicators in Turkey, the use of energy indicators is limited. The scarcity of energy resources makes the efficiency of energy used in irrigation networks extremely important. This study evaluated the performance of a pressurised irrigation network in Yozgat province of Turkey, using the indicators. The data obtained were compared with other countries in the Mediterranean region. The results showed that the specific energy value was about three times lower than other countries. However, when the energy consumed per unit irrigated area was examined, it was found that the irrigation network has high consumption of energy. The use of pressurised irrigation systems will be made mandatory in the coming years, as water resources are reducing because of climate change and drought occurring in the world. Thus, the need of energy for irrigation will increase correspondingly. The use of energy indicators in the planning and implementation of irrigation systems will make significant contributions to the performance of irrigation networks in the future.

This study assesses Turkey's competitiveness in the international commerce of agri-food items using harmonized product groups. The paper also looks at the future of agri-food markets in the EU and SCO. The study's primary goals were two-fold. The primary purpose was to examine if the Shanghai Cooperation Organization (SCO) could be a viable option for Turkey's agri-food exports to the European Union (EU). The second goal was to figure out whether Turkish agricultural products have a competitive edge in the SCO and EU markets. The study also looked at the competitiveness and long-term viability of Turkish agri-food exports to the EU and SCO markets. Exports, imports, foreign trade volume, foreign trade balance, exports to imports ratio, and the Lafay index (LFI) were used in the study as comparative advantage indicators. The survival function, based on the Lafay index, was also used to anticipate the export competition time for the EU and SCO markets. While the export-import ratio for fruits and vegetables was high, the ratio for live animals and animal feeds trade between Turkey and EU and SCO states was low, according to the research.

According to the data, Turkey had a competitive advantage in the export of fruits and vegetables, as well as in trade with the EU and SCO states. The study also discovered that the period of comparative advantage enjoyed by EU and SCO countries was not similar, and that the benefit was not consistent. Despite the fact that Turkey's international trade balance with the SCO nations has been fluctuating, its foreign trade with EU members has increased. As a result, Turkey should continue to trade in agri-food in the EU market while also increasing commercial connections with SCO countries.

It is widely known that the use of medicinal plants and probiotics as feed additives has a positive effect on growth, non-specific immune system, and resistance to diseases in aquaculture. This study examines the effects of dietary supplementation with sage (Salvia officinalis) and myrtle (Myrtus communis), alone or in combination with a probiotic mixture (PM) on growth, intestine microflora and histology, some antioxidant enzymes activities in the muscle tissues of rainbow trout (Oncorhynchus mykiss) and disease resistance against Vibrio anguillarum. For this purpose, fish were fed with a control diet of 1% sage, 1% myrtle, 1.1% probiotic mixture, 1% sage +1.1% PM and 1% myrtle+1.1% PM supplemented diets for 60 days. At the end of the trial, the fish fed the diets supplemented with myrtle and sage + PM showed a positive effect on feed conversion ratio. According to the histological assessment, the villi length, villi width and goblet cell numbers in the intestines of fish in all groups increased compared to the control. Superoxide dismutase activity in the muscles of fish in the PM group was higher than the fish in the other groups (p<0.05). The malondialdehyde activity was unaffected with the exception of the fish in the sage group (p<0.05). The lactic acid bacteria count in the intestines increased in fish fed the sage + PM (p<0.05). Fish fed the diets supplemented with sage + probiotic mixture, probiotic mixture, myrtle + probiotic mixture, and myrtle saw a significant reduction in mortality (0-32.5%) due to V. anguillarum compared to the control (63.2%) (p<0.05). In conclusion, the use of probiotics, sage and myrtle in combination as a feed supplement showed a positive effect on the growth performance, intestinal microflora and histology, and antioxidant enzymes activities and disease resistance in rainbow trout.

RESUMO: A avaliação da qualidade na e da Educação Infantil constitui-se como um campo de conhecimentos e práticas mobilizadores de aspectos estruturantes para a área, que transitam da competência dos diferentes agentes nos processos avaliativos aos seus efeitos na efetivação da política pública. Nos marcos de uma avaliação alinhada à promoção da qualidade e no reconhecimento da Educação Infantil como uma política pública submetida ao controle social, propõe-se a discussão sobre as potencialidades e tensões presentes na avaliação mista, um modelo de avaliação que combina procedimentos e instrumentos internos e externos às instituições. A discussão parte de uma experiência de avaliação mista realizada junto com a equipe técnica do Núcleo de Assessoria Técnica (NAT) do Ministério Público do Estado de São Paulo (MPSP), no âmbito do Grupo de Atuação Especial de Educação - Núcleo Ribeirão Preto (GEDUC-RP). Os resultados indicam que a avaliação mista foi potente devido ao seu formato dialógico: a avaliação externa possibilitou um olhar técnico e multiprofissional alinhado às proposições da política pública de qualidade; a avaliação interna promoveu uma autorreflexão coletiva da qualidade, mas evidenciou poderes diferenciados e fragilidades no que se refere ao olhar crítico de algumas instituições. Conclui-se que é no cruzamento destes olhares que se criam possibilidades de superação dos limites de cada tipo de avaliação e também convida à reflexão sobre os desafios que se instauram na dinâmica das relações entre as pessoas e órgãos públicos.
PALABRA ABIERTA - EDUCACIÓN INICIAL: LA ABISMAL DIFERENCIA ENTRE MIRAR ATENTAMENTE LA ESCENA EDUCATIVA Y “EVALUAR”
Authors: BRAILOVSKY DANIEL
Published: March 2023

RESÚMEN: En este ensayo pedagógico se propone analizar el contraste entre una concepción clasificatoria y medicional de la evaluación y un enfoque, contrario al anterior, susceptible de describirse como una mirada atenta y abierta que no busca “resultados a medir”, sino efectos y huellas interesantes de la enseñanza en la educación infantil. En la concepción medicional, evaluar es “valorar”, tomando como marco de referencia “lo que se espera” de los chicos junto a la pregunta “¿lo lograron?”. Y si no lo lograron se dice que están “en proceso”, que es el eufemismo para denominar el fracaso. En las antípodas de este paradigma tan instalado (y que se presenta como único e indiscutible) existen sin embargo otros lugares desde los que puede pensarse la evaluación, donde el marco de referencia es la intención, amorosa y honesta, de ofrecer enseñanza, cuidado y confianza a todos y a cada uno, sin mezquindad medicional, sin microscopio, sin clasificación, sin listado de competencias a ir alcanzando, sino con el deseo de entender y atender, de escuchar y de aprender. Se sostendrá aquí que para poder mirar educativamente los procesos pedagógicos de la educación infantil es preciso desandar las lógicas imperantes en términos de evaluación medicional, coherente con los sentidos de existencia de este nivel de enseñanza.
