Reduction of Cell Fusion by Deletion in the Hypervariable Region of the Spike Protein of Mouse Hepatitis Virus
Authors: Tennakoon Nipuna , Ryu Jihoon , Ujike Makoto , Taguchi Fumihiro , Shin Hyun-Jin
Published: February 2022

Deletions in the spike gene of mouse hepatitis virus (MHV) produce several variants with diverse biological characteristics, highlighting the significance of the spike gene in viral pathogenesis. In this study, we characterized the JHM-X strain, which has a deletion in the hypervariable region (HVR) of the spike gene, compared with the cl-2 strain, which has a full spike gene. Cytopathic effects (CPEs) induced by the two strains revealed that the size of the CPE produced by cl-2 is much greater than that produced by JHM-X in delayed brain tumor (DBT) cells. Thus, this finding explains the greater fusion activity of cl-2 than JHM-X in cultured cells, and we speculate that the deletion region of the spike protein is involved in the fusion activity differences. In contrast with the fusion activity, a comparison of the virus growth kinetics revealed that the titer of JHM-X was approximately 100 times higher than that of cl-2. We found that the deletion region of the spike protein was involved in fusion activity differences, whereas cl-2 produced significantly higher luciferase activity than JHM-X upon similar expression levels of the spike protein. However, the reason behind the growth difference is still unknown. Overall, we discovered that deletion in the HVR of the spike gene could be involved in the fusion activity differences between the two strains.

In February 2020, the municipality of Vo’, a small town near Padua (Italy) was quarantined due to the first coronavirus disease 19 (COVID-19)-related death detected in Italy. To investigate the viral prevalence and clinical features, the entire population was swab tested in two sequential surveys. Here we report the analysis of 87 viral genomes, which revealed that the unique ancestor haplotype introduced in Vo’ belongs to lineage B, carrying the mutations G11083T and G26144T. The viral sequences allowed us to investigate the viral evolution while being transmitted within and across households and the effectiveness of the non-pharmaceutical interventions implemented in Vo’. We report, for the first time, evidence that novel viral haplotypes can naturally arise intra-host within an interval as short as two weeks, in approximately 30% of the infected individuals, regardless of symptom severity or immune system deficiencies. Moreover, both phylogenetic and minimum spanning network analyses converge on the hypothesis that the viral sequences evolved from a unique common ancestor haplotype that was carried by an index case. The lockdown extinguished both the viral spread and the emergence of new variants.
LncRNA Expression Profiles in Canine Mammary Tumors Identify lnc34977 as a Promoter of Proliferation, Migration and Invasion of Canine Mammary Tumor Cells

Published: February 2022

Canine mammary tumor (CMT) is the most common tumor in canines after skin tumors. Long noncoding RNAs (lncRNAs) have crucial roles in human breast tumor initiation and progression, but the role of lncRNAs in canine mammary tumors is unclear. We analyzed the expression profiles of canine mammary tumors and their adjacent non-neoplastic tissue to explore abnormally expressed lncRNAs. LncRNA expression was detected by qRT–PCR. After overexpression of lnc40589 and knockdown of lnc34977 in CMT cells, CCK-8, colony formation, wound healing and Transwell assays were used to assess the proliferation, migration and invasive ability of canine mammary tumor cells. We also established a mammary tumor-bearing nude mouse model. GO analysis and KEGG pathway analysis demonstrated that the differentially expressed lncRNAs were closely related to the mammary tumor. lnc40589 was significantly upregulated and lnc34977 was significantly downregulated in CMTs. In addition, lnc40589 inhibits cell proliferation, migration and invasion, while lnc34977 promotes cell proliferation, migration and invasion. In addition, lnc34977 promotes the development of mammary tumors in animals. Taken together, our study results reveal the lncRNA expression profiles in CMTs and indicate that lnc34977 promotes the development of CMT both in cell culture and in vivo.

Published: February 2022

The consumption of illicit drugs represents a global social and economic problem. Using suitable analytical methods, monitoring, and detection of different illegal drugs residues and their metabolites in wastewater samples can help combat this problem. Our article defines a method to develop, validate, and practically applicate a rapid and robust analytical process for the evaluation of six naturally occurring cannabinoids (CBG, CBD, CBDV, CBN, THC, THCV), two cannabinoids in acidic form (CBDA, THCA-A), and the major cannabis-related human metabolite (THC-COOH). After SPE offline enrichment, we used a UPLC–ESI-MS/MS system, which permitted the determination of several by-products. Studied matrices were samples of different origins: (i) effluent water from a wastewater treatment plant in the Porto urban area; (ii) environmental water from Febros River, the last left-bank tributary of the Douro River. The multi-residue approach was substantiated and successfully employed to analyze the water samples collected in the above locations. The rapid and precise quantification of nine different cannabinoids in different water samples occurred within nine minutes at the ng L−1 level. The appearance of dozens of ng L−1 of some cannabis secondary metabolites, such as CBD, CBDA, CBN, THCA-A, indicates this plant species’ widespread usage among the general population in the considered area.

The article studies the factors of the formation of suicidal behavior in patients of a psychiatric hospital. For this, we studied 370 archival case histories of patients in psychiatric hospitals after committing a suicidal attempt and expressing suicidal thoughts before hospitalization, as well as patients with various mental disorders who committed suicidal attempts (81 people) and expressing suicidal intentions before admission to a psychiatric hospital (80 people). Clinical-psychopathological, experimental-psychological and psychometric examination methods were used. It was found that in the «archival» groups (with suicidal attempts and statements), there was a predominance of patients suffering from organic mental disorders, and among inpatients — schizophrenia. It was shown that in patients examined in a hospital using the Pierce scale, the most common were medium and high levels of suicidal intentions, and according to the C-SSRS scale, 50,0 % of them had the most severe suicidal ideas with a specific plan for their implementation. The highest frequency and duration of suicidal ideation was found in patients with personality disorders. It was shown that both according to the study of archival case histories and the results of inpatient examination, heredity aggravated by alcoholism was most often noted (25,4 % and 25,9 %), less often — mental disorders (15,4 % and 11,1 %). In patients after suicidal attempts more often than with suicidal statements, mild depressive disorder (33,3 % and 30,0 %) and depressive disorder of extreme severity (12,3 % and 7,5 %) were determined. When analyzing personality-psychological factors, it was found that in persons who committed suicidal attempts, rigidity (32,1 %), withdrawal (30,9 %) and excitability (25,9 %) prevailed. In general, the study showed that the prevention of suicidal behavior should be carried out in all patients, without exception, admitted to a psychiatric hospital with a suicidal mental pathology.
Military-political consequences of the events in Afghanistan: trends and their consideration in diplomatic practice
Authors:   Diplomatic Academy of the Ministry of Foreign Affairs of Russia, Moscow, Vinokourov Vladimir
Published: February 2022

The events taking place in the world as a result of the stampede of the United States from Afghanistan marked a radical change in the geopolitical and geostrategic picture of the world. As a result of these events, the United States of America in an instant turned into the ghost of a once powerful state, which has provided them with many allies and admirers until now. America came to the Middle East without understanding anything about its peculiarities, having squandered the lives of its own citizens and gigantic resources without any tactics and strategy. As a result, they suffered the greatest strategic blow in Afghanistan since the end of the Cold War. This also means the defeat of US allies, primarily NATO, who realized in mid-August 2021 that the US administration would not coordinate its actions with them on the issue of ending the Afghan mission. Thus, a serious problem for the United States after its strategic defeat in Afghanistan was the destruction of trust in Washington as an alliance partner and, as a result, the undermined prestige of the United States. The published article answers the question of what global consequences can be expected as a result of all this and how the impact of the Afghan catastrophe of the United States will manifest itself in the near and long term.
Influence of the Taliban capture of power in Afghanistan on the middle east situation
Authors:   Diplomatic Academy of the Ministry of Foreign Affairs of Russia, Ivanov Sergei
Published: February 2022

Hasty American withdrawal from Afghanistan after two decades of its occupation becomes not only the turning-point in the history of this long-suffering country, but in most essential way touches the situation in the world on the global level as well on regional one. Being close neighbor of Afghanistan the Middle East inevitably will be put under the pressure of the political, migration and other consequences as the result of the power change in Afghanistan. The Middle East region in its diversity and multi ethnical Afghanistan are close spiritually and culturally areas which confessing of most the same or similar faith. They are also close in view of traditional structure of their civil societies, strong tribe bases, cultural, sexual, moral and manners ways of life. As the result they have turned out to be the worldwide centers of the political extremism reproduction of different forms, became terroristically contagious. That’s why all these attempts to undermine existing and deep-rooted orders in these regions have been doomed to end in failure. The last and the most large-scale attempt of this kind, which has worldwide repercussions is the American adventure in Afghanistan. It has different consequences, the most crucial among them as far as the Middle East is concerned is shift in the balance of powers in the region, weakening of the American influence, a blow to American overmighty prestige among local ruling elites. All of that will have multi sides and less predictable, at least at the moment, results.
Iran’s position on Afghan settlement
Authors:   Diplomatic Academy of the Ministry of Foreign Affairs of Russia, Potapov Yury
Published: February 2022

The article notes the relevance of the problem of the Afghan settlement for Iran in the light of the radical changes that have occurred in Afghanistan after the rapid escape of the United States and its allies from Afghanistan and the rapid seizure of power in Kabul by the Taliban. The main factors, that force Iran to pay serious attention to solving the crisis in Afghanistan, are considered. The long land border with Afghanistan makes it difficult to control the situation at the border and illegal migration. Due to the ongoing anti-Iranian sanctions of the West and the lack of progress in negotiations on the revival of the JCPOA, Iran has to pay more attention to the development of cooperation with neighboring countries, including Afghanistan, which is one of Iran's main economic regional partners. Iran wants to play a leading role in the Afghan settlement process. Tehran is actively participating in the work of the Shanghai Cooperation Organization and other international organizations to resolve the Afghan crisis. Iran proposed to the UN to hold an international donor conference on Afghanistan and also to increase financial assistance to Iran to compensate costs connected with the accommodation of Afghan refugees. For this purpose, Iran also maintains regular bilateral contacts with all neighboring countries. Iran, on the one hand, seeks to prevent a new wave of Afghan refugees, smuggling of drugs and weapons into its country, and, on the other hand, intends to resume and expand economic cooperation with Afghanistan.
Using Finite Element Analysis in the 3D Printing of Metals
Authors: Alzyod Hussein , Ficzere Péter
Published: February 2022

Over the last few years, Additive Manufacturing, or as it is sometimes known, 3D printing, has become a significant research field for researchers worldwide. The necessity to increase the strength of materials and minimize their weight in the automotive and aviation industries has urged engineers and scientists to conduct more investigations and identify manufacturing methods to replace the classical ones. Additive manufacturing involves building a geometry layer by layer from a wide range of materials, which helps to utilize materials efficiently while minimizing the amount of waste produced as well as build complex, large geometries and light-weight components. Furthermore, it minimizes fabrication and processing times. In this paper, three different alloys were printed (TiAl6V4, AlSi10Mg and 316L) using MSC Simufact software to investigate the effect of changing machines on the effective stress and surface deviation. Furthermore, thermal analysis as well as mechanical, thermal and thermomechanical calibrations were carried out to determine a parameter set consisting of the laser power, inherent strains, fraction of exposure energy and volumetric expansion factor.
Gripper Finger Design for Special Purpose Applications

Published: February 2022

The trend towards collaborative robots is resulting in these "machine workers" working alongside humans in many workplaces. They can be used for a wide range of tasks and, most importantly, can rapidly switch between tasks. When it is no longer necessary for them to work at one location, they can simply be transferred to support another production process. With their universal gripper they can handle a wide range of tasks, however, custom accessories may need to be produced in specific areas. One such accessory could be sleeves that are mounted on the grippers to extend the use of the universal gripper. This paper aims to provide assistance on how to design these fingers.

Published: February 2022

Background

Early evidence has shown that anticoagulant reduces the risk of thrombotic events in those infected with COVID-19. However, evidence of the role of routinely prescribed oral anticoagulants (OACs) in COVID-19 outcomes is limited.

Aim

To investigate the association between OACs and COVID-19 outcomes in those with atrial fibrillation and a CHA2DS2-VASc score of 2.

Design and setting

On behalf of NHS England, a population-based cohort study was conducted.

Method

The study used primary care data and pseudonymously-linked SARS-CoV-2 antigen testing data, hospital admissions, and death records from England. Cox regression was used to estimate hazard ratios (HRs) for COVID-19 outcomes comparing people with current OAC use versus non-use, accounting for age, sex, comorbidities, other medications, deprivation, and general practice.

Results

Of 71 103 people with atrial fibrillation and a CHA2DS2-VASc score of 2, there were 52 832 current OAC users and 18 271 non-users. No difference in risk of being tested for SARS-CoV-2 was associated with current use (adjusted HR [aHR] 0.99, 95% confidence interval [CI] = 0.95 to 1.04) versus non-use. A lower risk of testing positive for SARS-CoV-2 (aHR 0.77, 95% CI = 0.63 to 0.95) and a marginally lower risk of COVID-19-related death (aHR, 0.74, 95% CI = 0.53 to 1.04) were associated with current use versus non-use.

Conclusion

Among those at low baseline stroke risk, people receiving OACs had a lower risk of testing positive for SARS-CoV-2 and severe COVID-19 outcomes than non-users; this might be explained by a causal effect of OACs in preventing severe COVID-19 outcomes or unmeasured confounding, including more cautious behaviours leading to reduced infection risk.
Estado de excepción en tiempos de pandemia Covid-19: Sus efectos en personas en situación de trabajo informal
Authors: Ramirez Toapanta Cristhian Leonardo
Published: February 2022

El presente artículo analiza la figura jurídica del estado de excepción dentro del contexto de la pandemia Covid-19 y sus efectos en las personas en situación de trabajo informal. Los efectos de la pandemia en Ecuador fueron alarmantes, por existir deficiencia en el sistema sanitario y debido a la ausencia de un sistema de control de riesgo eficiente; por ello el ejecutivo declaró un estado de excepción con toque de queda y cuarentena por tres meses. El objetivo del artículo es analizar el marco constitucional respecto a los diferentes estados de excepción aplicados en Ecuador y los efectos que tuvo la paralización de actividades comerciales de carácter informal, utilizando el método descriptivo y analítico. El Estado ecuatoriano deberá aceptar la nueva realidad y tomar medidas para reactivar la economía, creando plazas de trabajo y mejorando las condiciones de trabajo informal. La investigación se realizó utilizando el método descriptivo y analítico, estructurando el contenido del artículo a través de ideas generadas a partir del ámbito jurídico de un estado de derechos. Para finalizar se entiende que el estado de excepción es una figura jurídico-político que a través de la historia ha sido mal utilizada por gobiernos autoritarios que so pretexto de superar una crisis nacional.

Published: February 2022

Objectives: The aim of the current study was to assess the effects of hesperetin on damage to kidneys as remote organs following skeletal muscle ischemia-reperfusion (IR) in rats. Materials and Methods: In general, 30 male Wistar rats were randomized and placed into sham, IR, hesperetin, dimethyl sulfoxide (DMSO), and IR+hesperetin groups. The rats in the hesperetin and IR+hesperetin groups received a 50 mg/kg dose of hesperetin dissolved in DMSO intraperitoneally. In the IR+hesperetin group, hesperetin was injected exactly prior to reperfusion. To induce skeletal muscle ischemia, the femoral artery was clamped for two hours. Following a 24-hour period of reperfusion, the samples of blood were collected for renal function tests and oxidative stress measurements. Next, the rats were euthanized, and histological analyses were conducted on their removed kidneys. Results: Based on the results, urea and creatinine serum levels were significantly higher in the IR group (P<0.05) whereas they significantly reduced following treatment with hesperetin (P<0.05). The concentration of malondialdehyde (P<0.05) increased for the IR group while those of superoxide dismutase (P<0.05) and glutathione peroxidase (P<0.05) activities were lower than the other groups. The analysis of renal tissues in the IR group showed glomerular necrosis, degeneration, and necrosis of the tubular epithelium, protein casts, interstitial edema, and inflammation. Finally, the degree of renal injury was significantly ameliorated (P<0.05) in rats treated with hesperetin. Conclusions: Overall, the results indicated that in rats, hesperetin could reduce renal injury that has been induced through skeletal muscle IR.

Notas sobre el proceso de enseñanza-apredizaje del oficio en su dimensión técnico- instrumental y la recuperación de nuestras tradiciones
Authors: Travi Bibiana
Published: February 2022

En este trabajo   se   abordarán   algunas   cuestiones   referidas   a la Formación Profesional en Trabajo Social y, en particular, al proceso de enseñanza-aprendizaje del oficio en su dimensión técnico-instrumental.

En el texto se recuperan reflexiones y escritos elaborados a lo largo de más de dos décadas de docencia y ejercicio profesional, así como la exposición realizada el 2 de Julio de 2012 en el Acto Académico or- ganizado por la Carrera de Trabajo Social de la Universidad Nacional de Rosario, en el que se presentó el cambio de fecha de la conme- moración del “Día del Trabajador Social” en Argentina. Considero que determinar, institucionalizar, una fecha específica para conme- morar, celebrar nuestro día, es sin duda una práctica de afirmación- interpelación-construcción de la identidad y de la memoria colectiva. Y dado que la identidad y la memoria no pueden prescindir de sus protagonistas, de quienes forjaron, soñaron, pensaron, enseñaron, escribieron y en definitiva “inventaron” el Trabajo Social, se hará mención en primer lugar a reflexiones y propuestas elaboradas en los orígenes de la profesión.
Hablamos de niñas
Authors: Aucía Analía E.
Published: February 2022

El interés de este trabajo es mostrar la tensión existente entre ciertas prácticas estatales que ejercen violencia contra las mujeres y las normativas que protegen a las mujeres de todas las formas de violencia y discriminación que deben ser aplicadas por esas mismas instancias estatales. Para tal fin, se analizan cuatro situaciones en las que diversos agentes estatales ejercieron violencia institucional hacia niñas de entre 9 y 12 años. La elección de trabajar con situaciones que afectaron a niñas responde, fundamentalmente, a que el Estado debe tomar medidas de especial protección por la condición de infantes. El análisis de tal accionar busca visibilizar lo que la propia actuación estatal invisibiliza mostrando la responsabilidad del Estado en la producción de violencia cuando su obligación es eliminarla. Para esto se hará referencia a las normativas vigentes que delimitan el marco de legalidad y la ética de nuestras prácticas, haciendo hincapié en la relevancia de los instrumentos de derechos humanos. Para comprender la naturalización de ciertas formas de violencia instalada en las prácticas y discursos institucionales, se analizarán brevemente algunas maneras en las que el conocimiento filosófico ha sostenido la construcción de las identidades de género y la desigualdad que le es propia.

La Edición número 12 de nuestra Revista Cátedra Paralela, que aquí compartimos, pretende continuar con el trabajo y el compromiso asumido en torno a la producción de conocimiento y la construcción de espacios de debate colectivos en nuestra profesión. Reafirmamos en este número, nuestra tarea de defender los espacios de reflexión en Trabajo Social, favoreciendo el diálogo e intercambio entre el colectivo de docentes, graduadxs y estudiantes, a través de la socialización y divulgación de diversas sistematizaciones y producciones académicas y de experiencias profesionales. Así, en la presente edición lxs lectorxs encontrarán una serie de artículos que reflexionan y problemati- zan sobre distintos temas de interés para el Trabajo Social.

La problematización de lo dado, como ejercicio constante sobre nuestras formas de conocer e intervenir, se convierte en la clave para la construcción de un sentido crítico, en tanto convicción de cambiar radicalmente nuestra propia concepción de lo posible y lo real. Sentido crítico que habilite prácticas de resistencia frente a las múltiples formas cotidianas de la opresión; que apueste, como nos enseña Judith Butler, a la visibilización de lxs invisibles y a la palabra de lxs indecibles: “Lo importante es negociar el derecho a hablar y asegurarse de que los que no tienen voz logren su derecho a hablar (…) ¿qué significa reivindicar derechos cuando no se tiene ninguno? Significa traducir al lenguaje dominante, pero no para ratificar su poder, sino para ponerlo en evidencia y resistir a su violencia diaria y para encontrar el lenguaje a través del cual reivindicar los derechos a los que uno no tiene todavía derecho” (Judith Butler, 2009).

formación continúa en Trabajo Social
Authors: Gonzalez Saibene Alicia
Published: February 2022

En el presente artículo se aborda un conflicto cen- trado en la tensión entre la formación universitaria, orientada a la profundización teórico-epistemológica y de los marcos operativos, y el desempeño del ejercicio profesional, alejado de la considera ción de aprendizaje permanente. Tanto el ámbito universitario cuanto las organizaciones de políticas sociales espacios específicos de intervención profesional del/la Trabajador/a Social deberían revisar los principios regula- dores de su «cultura organizacional» para adecuarse a los tiempos que corren. La formación universitaria, alcanzada por los avatares de la crisis social, económica, política, cultural y subjetiva que atravesamos, ha visto decaer su excelencia en el grado, y ha promovido la oferta de posgrado desde hace más o menos una década como forma de enfrentarla, no sin críticas. Por su parte las organizaciones, tanto gubernamentales como no gubernamentales, carecen de interés en fomentar o sostener en su seno la formación continua o capacitación en servicio. Este escaso o inexistente interés parece deberse a la comprensión desde mi perspectiva, equivocada de que la obtención del título de grado es el final de la formación profesional. Contra esta idea, sostengo que la misma debe pensarse como un proceso continuo y permanente de capacitación
Trabajo Social y las Matrices Culturales:
Authors: Sosa Ruth
Published: February 2022

El presente artículo intenta delinear algunas cuestiones generales en relación a las matrices culturales y el trabajo social y entabla una vinculación entre aspectos inherentes a una epistemología del trabajo social latinoamericano y las consecuencias prácticas, materializa- das en el campo de intervención. Para este abordaje incorporamos el papel de los movimien- tos sociales en la sociedad argentina y latinoamericana y vislumbramos la forma cómo interpelan al conjunto de las profesiones sociales en un contexto pretendidamente

«globalizador». Dicho contexto «globalizador» tiende a producir, como función ideológica, una neutralización de las tensiones existentes en el tejido social, y opera un efecto aparen- temente homogeneizador, lo que acaba constituyendo una amenaza y una constante ofen- siva a aquellas culturas dotadas de autonomía y que se resisten a entrar en la lógica que el capitalismo neoliberal pretende universalizar
Pobreza y género en los programas sociales «contra la pobreza» en Catamarca
Authors: Veron Ponce María Belen
Published: February 2022

Se presentan algunos avances de la investigación que responde a la pregunta: ¿Cómo se definen en el discurso de los programas   sociales   la   «pobreza»   y   las «relaciones de género» en cuanto a: destinatarios de las acciones, estrategias de intervención y contenido de los beneficios? Analizamos   los   discurso   de   programas «Emprendedores» de la Dirección de Desarrollo Local y Economía Social y «Pro Familia» de la Dirección de Políticas de Promoción Socio Alimentaria (Secretaria de Desarrollo Social de Catamarca) empleando el método de análisis sociológico del discurso, conforme a la propuesta teórico- metodológica de Costa y Mozejko (2001). Considerando el discurso como «práctica y proceso»,   observamos   el   proceso   de «enunciación» donde el agente que produce el discurso, pone en juego sus recursos diferenciados de relación y competencias, que en un campo de fuerzas busca legitimar su discurso. Identificamos los destinatarios del «discurso político», luego se explicita las competencias y valores desde los cuales el enunciador buscar legitimarse. Reconocemos una continuidad entre las conceptualizaciones de pobreza y género (como se construye al enunciatario), las estrategias de intervención que se plantean y el contenido de los beneficios. Sosteniendo la hipótesis de que si bien en el discurso, los programas sociales se construyen como garantes de derechos, persisten en ellos visiones del sujeto y relaciones de género reproductoras de los roles tradicionales (asignados a varones y mujeres), que impiden el ejercicio pleno de ciudadanía de los mismos.

El presente trabajo invita a pensar “viejos problemas”, como el del trabajo esclavo, desde una matriz conceptual que ponga en diálogo diferentes cientistas y pensadores sociales, en un contexto social y económico determinado. Asimismo, evaluar el desarrollo de una reflexión crítica y comprensiva sobre la problemática de las relaciones de trabajo en la sociedad actual, así como las interacciones surgidas entre los actores que dan cuerpo a las relaciones laborales (Estado, sindicatos y mercado) dentro de la actualidad regional, nacional e internacional. El análisis y la reflexión de este artículo intenta abordar, entre otros, los siguientes interrogantes: ¿cómo es posible, frente a las promesas de la Modernidad, que nos encontremos aún ante situaciones de servidumbre y de esclavitud?, ¿cuáles son las causas que permiten que el trabajo esclavo perdure en la sociedad contemporánea?, ¿se trata de una problemática exclusiva de los países en vías de desarrollo?, ¿contribuye pensar en soluciones o alternativas desde el mismo sistema capitalista?

Presentamos la edición número 9 de nuestra Revista Cátedra Paralela, reno- vando el compromiso de sostener este valioso espacio de divulgación y reflexión que contribuya al enriquecimiento de docentes, graduados/as y estudiantes de Trabajo Social.

Creemos que es necesario promover una reflexión teórica que dé orientación y sentido a la acción, no en términos de “aplicabilidad de la teoría”, sino de un serio trabajo del concepto que provea de herramientas para iluminar nuestra lec- tura de la realidad y permita a nuestra intervención profesional estar a la altura de los desafíos que le impone el tiempo actual. En este sentido, coincidimos con Susana Malacalza en que “restituir lo político como fundamento es uno de los aspectos fundamentales al que deberemos hacer frente docentes, graduados y estudiantes si queremos una transformación radical de nuestra profesión en concordancia con los cambios radicales de la sociedad” (2003:151).

The evaluation process is not an independent entity of teaching, they are inseparable processes, over more than 20 years of experience as a higher-level teacher, I have verified first-hand that the moment of greatest tension for students occurs In the evaluation periods, the exams generate a number of reactions and the grades lead to comments that have common foci regardless of the semester or degree being taken, it is heard that the students are not satisfied with the grades they receive, because they consider that They are not a reflection of their actions, that they were not equitably valued, that the evaluation criteria are incomprehensible, that teachers qualify arbitrarily. Therefore, the work that is presented is the result of a documentary investigation that seeks to understand student discontent, to provide theoretical and methodological elements to teachers that allow improving evaluation practices and thus, positively influence the performance of students. students. We begin the approach by inquiring about the origin of the term, the foundations, characteristics and purposes are exposed; Thus, like each of the stages, a description is made of the evaluating trend in Mexico and its inheritance derived from the industrialization process of the United States with scientific nuances influenced by the quantitative paradigm with a technocratic and summative approach.

Penelitian ini merupakan penelitian kualitatif dengan pendekatan deskriptif, bertujuan untuk mengidentifikasi kemampuan komunikasi matematis berdasarkan disposisi matematis pada materi persamaan garis lurus. Subjek penelitian ini ialah siswa kelas VIII  yang mewakili setiap kategori disposisi matematis yaitu tinggi, sedang, dan rendah. Teknik pengumpulan data dilakukan dengan pemberian angket, tes, dan wawancara. Hasil penelitian menunjukkan bahwa seluruh siswa pada setiap kategori disposisi mampu menuliskan solusi secara sistematis dan mampu menggunakan simbol matematika dengan tepat. Namun, siswa DMR kurang mampu memahami masalah sehingga terdapat kekeliruan penyelesaian. Perbedaan kemampuan siswa terlihat dari kemampuan menggambarkan grafik. Siswa DMT menggambarkan grafik dengan tepat. Sedangkan, siswa DMS menggambarkan grafik yang kurang tepat. Adapun, siswa DMR tidak mampu menggambarkan grafik solusi dari soal.Kata Kunci: Kemampuan, Komunikasi Matematis, Disposisi Matematis, Persaman Garis LurusThis research is qualitative research with a descriptive approach, aiming to identify mathematical communication skills based on mathematical disposition in straight-line equation matter. The subject of this research are students of class VIII who represent each category of mathematical disposition that is high, medium, and low. Data collection techniques are done by giving questioner, tests, and interviews. The results showed that all students in each disposition category were able to write solutions systematically and were able to use mathematical symbols appropriately. However, DMR students are less able to understand the problem so there is a mistake in solving it. The difference in students' abilities can be seen from the ability to graph. DMT students draw graphs precisely. Meanwhile, DMS students draw inappropriate graphs. As for the subject, DMR students are not able to draw a solution graph of the problem.Keywords: Ability, Mathematical Communication, Mathematical Disposition, Straight Line Equation
