Nevus of Ota: Combination Treatment with Q-Switched neodymium-doped yttrium aluminum garnet laser and fractional CO2 laser
Authors: Mann Khushpreet Kaur , Khunger Niti , Yadav Amit Kumar
Published: November 2023

Background:

Nevus of Ota is a facial dermal melanocytic hamartoma occurring more commonly in Asians. The mainstay of treatment is 1064-nm Q-Switched neodymium-doped yttrium aluminum garnet (Nd:YAG) laser, which has shown variable results in pigmented skin.

Objective:

The aim of this study was to determine whether Q-Switched Nd:YAG laser treatment combined with fractional CO2 laser is more efficacious than Q-Switched Nd:YAG laser alone.

Materials and Methods:

This was a prospective study with 81 patients. The patients were randomly divided into two groups. Group 1 received 1064-nm Q-Switched Nd:YAG laser alone and group 2 in addition received a fractional CO2 laser as well. Both groups received six sittings at monthly intervals. The treatment response was documented with physician global assessment (PGA) and patient’s treatment satisfaction on Wong–Baker Facial Pain Scale (WBFPS). Dermoscopic evaluation was done to see subsurface pigment clearance.

Results:

In the combination group, 25% of patients had more than 50% improvement as compared with 5.71% in group 1. To achieve a mean PGA score of 1.4, it took six sessions for group 1 versus only four for group 2. Dermoscopic evaluation showed faster pigment clearance in the combination group.

Conclusion:

Combining two lasers shows statistically significant faster and greater degree of improvement as compared with Q-Switched Nd:YAG laser monotherapy in nevus of Ota.

Severe burn injury affects the body in many devastating ways, the most severe being systemic inflammatory response syndrome. This results in a myriad of effects like increasing capillary permeability, thereby fluid loss. It also causes a surge in inflammatory mediators like interleukin (IL)-6, which further increases the capillary leak and fluid loss. This results in refractory hypotension in patients despite adequate fluid resuscitation. Plasma exchange has been used in the management of a number of illnesses with a significant inflammatory component, and, therefore can be considered to have a role in burn injury. In our article, we would like to share our experience of using therapeutic plasma exchange therapy in burn patient
Hypodermic needle as a safe and easy mini cotton bud applicator for chemical cautery
Authors: Mukhtar Muhammed
Published: November 2023

To simplify the chemical cautery, micropipette and syringe outlet are stuffed with cotton wick for a better flow of chemical due to capillary action. However, the corrosive effect of chemicals on metallic needle and on rubber/plastic cap of the piston leads to the leakage of chemicals. Hypodermic needle and tooth picks have been used for chemical cautery, but it requires frequent dipping into the chemical, which is not safe. A bent (hooked) hypodermic needle is described as an alternative for safe, quick, and precise cauterization of multiple small skin lesions.
Face transplantation: What you need to know?
Authors: Boppana Sri Harsha , Simhachalam Kutikuppala L V , Kalyani Ponnaganti S V
Published: November 2023

Since the 1990s, face transplants have gotten a lot of press and public attention across the world. After a transplant was disclosed in November 2005, the first recipient, Isabelle Dinoire, found herself at the center of a spectacular event of surgical innovation. Up till August 2020, 47 transplants have been performed globally (including two retransplants), all of which have received substantial media attention. Hundreds of publications addressing the procedure’s medicinal, physical, psychological, and ethical ramifications have been published in the scholarly literature, far outnumbering the procedure’s occurrence. Face transplants have also appeared in films, television shows, and novels, indicating a desire to explore the social and interpersonal consequences of face variance. This is an attempt to present a comprehensive context of face transplantation progress and practice, based mostly on extant documentary sources. It traces the history of face transplants, identifying major milestones and themes along the way and focusing on its development as a therapeutic option for individuals with severe facial abnormalities. There are still important questions to be asked about the patient’s perspective, as well as the complex philosophical and sociological meanings of the face, but this article focuses on the institutional and cultural factors that have allowed for such an ethically complex and radical surgery to take place. Opportunity and financial feasibility are among them, as are expertise, ambition, and an awareness of patient needs.
Valsalva maneuver to identify dermal bleeders after paramedian flap elevation under local anesthesia
Authors: Brown Alistair Campbell , Nelson Toby , Nelson Sarah C
Published: November 2023

The paramedian forehead flap (PFF) provides a reliable reconstruction option for complex nasal tip defects. The robust blood supply from a well perfused pedicle allows for reconstruction of large defects of the nasal tip for which simpler methods/techniques would provide inadequate coverage or result in inferior cosmesis. A well-designed PFF containing the supratrochlear artery inherently predisposes to small vessel bleeding from the pedicles cut edge. Due to the well perfused nature of the pedicle, there is an increased risk of post-operative bleeding. We describe a technique for better identifying bleeding points from the pedicle to optimise intra-operative haemostasis by performing the Valsalva maneuver using a syringe intraoperatively.

The Evolution of Configuration Management (CM) Into an Accelerating Digital World
Authors:   G-33 Configuration Management
Published: November 2023

The purposeful integration of existing and emerging technologies into CM practice will enable collaboration with supporting systems and provide stakeholders access to authoritative and trusted data in a timely fashion at their desktop to help drive educated decision making. This lays to rest the misguided myth that CM and supporting systems operate at cross-purposes.

What does it mean to have CM in a world of new initiatives and 2-week sprints (i.e., time-boxed work periods), multiple increments producing Minimum Viable Products (MVP) and synchronized with Model Based Systems Engineering (MBSE) while being digitally transformed? MBSE initiatives drive the jump from “2D” data to “3D” data, thereby becoming a Model-Centric practice. Products now enable technology to push the product lifecycle management process to new levels of efficiency and confidence. This mindset is evidenced by five major functions of CM, as discussed below, and described in EIA-649C.

Celem artykułu jest dokonanie analizy porównawczej stolic Europy Środkowej, powyżej jednego miliona mieszkańców, tj. Warszawy, Pragi i Budapesztu, w zakresie stopnia rozwoju idei miasta zielonego (green city). W tym celu przeprowadzono analizę treści dokumentów strategicznych i baz danych miast Unii Europejskiej. Dzięki analizie statystycznej umożliwione zostanie przedstawienie stopnia rozwoju realizacji idei green city w miastach postsocjalistycznych. Miasta zostaną poddane ocenie, w ramach których wykazane zostaną ich walory i niedoskonałości względem wzorca miasta zielonego. Aby określić stopień rozwoju badanych miast, podjęto próbę uzupełnienia definicji samego miasta zielonego, poprzez określenie faz jego rozwoju. Artykuł ma zatem charakter aplikacyjny, a jego celem szczegółowym jest możliwość ukierunkowania miast Europy Środkowej w implementacji koncepcji green city.

The concept of a green city: a comparative analysis of Central European cities (Warsaw, Prague and Budapest)

The main aim of the article is to compare the implementation of the green city concept in capital cities above 1 million population in Central Europe, i.e. Warsaw, Prague and Budapest in order to evaluate the degree to which each of these cities implement the assumptions of the abovementioned concept to achieve urban sustainability. An analysis of strategic documents on urban planning as well as data bases of the three cities was carried out. The results allowed for measuring the progress and effectiveness of the environmental policies of these cities and determining their achievements and shortcomings when it comes to realizing the green city model. Additionally, for the purpose of this research, an attempt at elaborating the definition of a ‘green city,’through determining four phases of its development, was made. Thus, the article is solution-specific, in that it points at possibilities of the development of Central European cities as regards the implementation of the green city concept.
Wpływ ceny kontraktów terminowych EUA i uzyskiwanych z ich sprzedaży środków na inwestycje rządowe państwa polskiego w odnawialne źródła energii w latach 2013–2020
Authors: Palac Piotr
Published: November 2023

Artykuł przedstawia ocenę zależności inwestycji rządowych w odnawialne źródła energii (OZE) od ceny kontraktów terminowych na emisję CO2 (EUA) oraz ilości środków uzyskanych przez Polskę w wyniku ich sprzedaży w latach 2013–2020. Celem artykułu było sprawdzenie, czy taka zależność istnieje, oraz wskazanie głównych powodów jej występowania bądź jej braku. W badaniu zastosowano metodę porównawczą, opisową, graficzną, a także przeprowadzono badanie korelacji przy pomocy współczynnika korelacji Pearsona oraz częściową kwerendę literatury. Wynika z niego, że inwestycje rządowe państwa polskiego w odnawialne źródła energii w latach 2013–2020 nie były zależne od ceny kontraktów EUA, pomimo korelacji wzrostu cen uprawnień i zwiększenia udziału źródeł odnawialnych w kreacji energii w latach 2018–2020. W Polsce, w latach 2013–2019, około 75% nakładów finansowych na inwestycje w OZE pochodziło od prywatnych instytucji i podmiotów gospodarczych. W tych latach nakłady spółek energetycznych z udziałem Skarbu Państwa na inwestycje w odnawialne źródła energii stanowiły zaledwie 7% wszystkich nakładów.

Influence of the EUA Futures contract prices and the money resources obtained from their sale on the 2013–2020 Polish government investments in renewable energy sources

The article presents an analysis of the relation between the scale of Polish government investments into renewable energy sources and the price of EUA Futures contracts and funds obtained by Poland from their sale in the years 2013–2020. The goal of the analysis was to check if there is any relationship between the funds obtained from the sale of EUA contracts and Polish government investments in renewable sources of energy. The theoretical section contains a partial research of sources, whereas the analytical part uses the comparative, descriptive and graphic methods, as well as Pearson correlation coefficient. The results of the study indicate a lack of relationship between the EUA prices and Polish government investments in renewable energy sources in 2013-2020. The study shows that, at that time, about 75% of investments expenditure for renewable energy sources in Poland came from private institutions and business entities and only 7% of the financial outlays came from state-owned energy companies.
Awakening a Sense of Injustice
Authors: Stoudt Brett
Published: November 2023

Rockport is an elite, all boys, day school in the northeast United States. It educates mostly white, wealthy, young men. Student researchers, faculty researchers and I collaborated to study bullying at Rockport using an approach to research known as participatory action research (PAR). In the process we also gained a better understanding of how privilege, especially gendered privilege, was socialized and (re)produced. The participatory research spaces that emerged in our project - grounded in the experiences of students, teachers, and administrators - facilitated critical awareness of self and context that Deutsch (2006) referred to as "awaking the sense of injustice." Over the course of a year, our research at Rockport collected data of local consequence and in doing so, built institutional momentum that has since become a school-wide and ongoing initiative to address bullying. As a result, this work was a form of counter-hegemonic action.
Critical Positive Masculinity
Authors: Lomas Tim
Published: November 2023

Although theorists like Connell (1995) have emphasised diversity in men and masculinities, there remains a tendency to present masculinity in singular terms as an assemblage of toxic traits, constructing men as ‘damaged and damage doing’ (Mac an Ghaill & Haywood, 2012). However, an emergent body of work suggests men are able to resist or define traditional norms to negotiate a more ‘positive’ construction of masculinity, e.g., conducive to health. Thus the present article makes the case for introducing a new perspective within the study of men and masculinities: Critical Positive Masculinity. Influenced by the field of positive psychology, this perspective draws together work showing the potential for men to find more constructive ways of doing masculinity, including a series of articles on men adopting new masculine practices through involvement with meditation. However, drawing on the Critical Studies on Men approach, the new perspective still seeks to problematize men and gendered power relations, as even ostensibly ‘positive’ forms of masculinity can have deleterious consequences for marginalised groups. Critical positive masculinity offers a fresh perspective that is neither fatalistically negative nor naively optimistic about the possibility for positive change in men.
Mirando a los Hombres: Una Aproximación a la Percepción que Tienen de los Hombres las Estudiantes y los Estudiantes Universitarios de Educación Infantil y Primaria
Authors: Martinez González Alejandro , Rodríguez Fernández-Cuevas Andra , Bonell García Lars
Published: November 2023

Los últimos estudios e investigaciones ponen en evidencia el importante papel que el personal docente desempeña desde el ámbito escolar a la hora de abordar y contribuir a la consecución de la equidad de género, para lo cual resultan determinantes sus propias percepciones sobre masculinidad y feminidad. En este artículo se presentan los resultados de un trabajo de investigación que, en torno a esta cuestión, se ha realizado con alumnado universitario de Educación Infantil y Educación Primaria del Centro Universitario La Salle-UAM, por su condición de futuros referentes en la socialización de la infancia así como en la construcción de su identidad de género, en el que se ha podido indagar acerca de tres cuestiones relevantes: el mantenimiento de determinadas concepciones hegemónicas acerca de la masculinidad, las valoraciones tanto positivas como negativas que de estas concepciones hacen tanto mujeres como hombres, y las vías y posibilidades para la superación de las posiciones masculinas hegemónicas que causan más rechazo tienen mucho que aportar.
Storytelling as Methodology: Colombia’s Social Studies Textbooks after La Constitución de 1991
Authors: Daza Stephanie L.
Published: November 2023

This article posits the concept-metaphor of “storytelling as methodology” for reading a Colombian social studies textbook after the country ratified a new constitution in 1991. It examines temporal interplay and the interplay between visual and written texts in the textbook in order to analyze US imperialism, race/difference, and the discourse of progress. At the same time, the article draws on the theoretical perspectives of Gayatri Spivak in its attempt to perform transnational academic work within the limits of translation.
Photographic Images of Refugee Spatial Encounters: Pedagogy of Displacement
Authors: Subedi Binaya
Published: November 2023

This paper examines my effort to document the experiences of a Bhutanese refugee community in a mid-western city of the United States. In particular, the essay looks at housing experiences the community encountered and my efforts to translate the events through photographs. The essay also explores how oppression operates in relation to refugee experiences. Recognizing that knowledge of recent refugees of color has been absent and perhaps may not be addressed in school curriculum in the near future---the photo essay project was created to serve as a curriculum about marginalized communities who are invisible in the curriculum. By using photographs, I explore three conceptsthat may help us examine the relationship between space and politics: (1) ideal spaces (2) violated spaces (3) damaged spaces. Lastly, by examining refugee experiences, the paper examines pedagogical approaches to utilizingphotographs to document oppression.
Care of the Postcolonial Self: Cultivating Nationalism in The Philippine Readers
Authors: Coloma Roland Sintos
Published: November 2023

The article examines the cultivation of revolutionary nationalism and the production of postcolonial subjectivity under a foreign regime. The analysis centers onThe Philippine Readers, one of the longest published and most widely adopted reading series for elementary students in grades 1 to 7 in the Philippines from 1920s to 1960s. Due to its use and scope, the Readers significantly impacted the development of Filipino mind, character, teaching, and learning for generations. The article mobilizes Michel Foucault’s notion of care of the self, whereby individuals undergo intensive self-scrutiny through texts that serve as manuals for living. It contends that the Readers functioned as a crucial guide that enabled Filipinos to care for themselves in instilling furtive yet subversive forms of nationalism under United States rule. More specifically, two forms of nationalism are discussed, and the concepts of covert and hybrid nationalism are situated within scholarly discussions regarding colonial complicity and opposition as well as Western and indigenous influences.
Claves para el Desarrollo del Plan de Convivencia en los Centros Educativos desde una Perspectiva Integral
Authors: Torrego Juan Carlos , Martínez Concepción
Published: November 2023

Este artículo muestra las principales conclusiones obtenidas en una investigación realizada en un centro de Educación Secundaria de Madrid (España). Su propósito ha sido conocer y comprobar cómo se están desarrollando en la práctica, los planteamientos que sobre convivencia se han realizado desde marcos de intervención global, como el que se propone en el Modelo Integrado (Torrego, 2006, 2008), así como identificar aspectos claves para el desarrollo de planes de convivencia en los centros educativos.Es una investigación cualitativa, realizada mediante un diseño de Estudio de Caso Único, donde se han combinado técnicas de análisis de documentos y datos, con la realización de entrevistas en profundidad a diversos miembros de la comunidad educativa. El interés del caso radica en que el centro trata la convivencia desde una perspectiva global, sobre la base del citado modelo integrado y en que destaca por los buenos resultados obtenidos en la mejora de la convivencia en los últimos años.Las conclusiones ponen de manifiesto la importancia de abordar la convivencia desde una perspectiva integral acorde con las características del contexto, que contemple aspectos curriculares, estructuras específicas para la mejora de la convivencia y que promueva la participación democrática de la comunidad educativa; además se evidencia la necesidad de una formación específica en convivencia, el papel central de la acción tutorial y de las metodologías cooperativas. Los aspectos detectados que precisan un mayor desarrollo son: la generalización de la formación en convivencia a todo el alumnado, la profundización en las medidas curriculares, la mejora de la acción tutorial y la generación de recursos adecuados para intervenir en los casos del alumnado con más dificultades.
The (Mis)use of Technology in the National Accreditation System
Authors: Munson April
Published: November 2023

The use of technology in the evaluation of higher education programs is a mainstay. Physical evidence rooms, face-to-face interviews, and reviewing of documentation on site have become obsolete. Relying on the heavy use of technology in the evaluation process has allowed what some believe to be a more cohesive, streamlined approach to the presentation of data, however, many face serious concerns with the reliance on technology; what is lost? Missed? nappreciated? How much is the understanding of technology and ability to present the "show" digitally impressing the reviewers verses actual quality of programs and institution?
Sharing Resources in Open Educational Communities
Authors: Tosato Paolo , Carramolino Arranz Beatriz , Rubia Avi Bartolomé
Published: November 2023

The spread of Internet and the latest Web developments have facilitated the connection between teachers, learners and institutions, as well as the creation and sharing of new open educational resources (OERs). Despite this, many projects and researches paid more attention on content distribution, focusing on their format and description, omitting the relationship between these materials and the collaborative environments.In this article we sustain that is more important to share resources in open educational communities (OEC) than in open educational repositories, establishing a relationship between OERs and collaborative environments, promoting the qualification of social activities and the creation of networks among users. Notwithstanding, a couple of surveys that involved more than 300 teachers at European level have highlighted how stimulating collaboration among teachers, both online and in presence, is not simple; even if, when this happens, it seems to be a good way to promote formal and informal learning, and innovation in professional practices. As it is possible to infer from the surveys’ data, users can significantly improve the efficiency of their learning if they take active part in a network, which can act as a support to help teachers to address the new challenges of the digital era.
Mathematics Education and Ethnomathematics. A Connection in Need of Reinforcement.
Authors: Palhares Pedro
Published: November 2023

In this article we analyze Ethnomathematics research in Portugal in the recent past and the way it has been used in Education. We divide our reflection in three main parts. One is about people’s discourse and actions and how to use them to uncover mathematical thinking. The second is about artifacts and how to use them to uncover mathematical thinking. The third is about how to use ethnomathematics research to improve mathematics education. In each of these sections we reflect on some of what has been made and we propose paths we think are worth pursuing.
Enseñar matemáticas en la sociedad de mañana: alegato a favor de un contraparadigma emergente
Authors: Chevallard Yves
Published: November 2023

El análisis histórico de la enseñanza de las matemáticas en secundaria muestra cómo se han ido sucediendo en el tiempo diferentes paradigmas escolares. En este trabajo se describe y se analiza un nuevo paradigma didáctico, todavía en su infancia, el paradigma del “cuestionamiento del mundo”, que se basa principalmente en cuatro conceptos interrelacionados, el de la indagación y el de ser “herbartiano”, “procognitivo”, y “exotérico”. La ambición del autor es mostrar, aunque sea de manera sucinta, cómo la actual crisis en la educación matemática se podría con suerte resolver según estas líneas, descartando el recurso a estrategias que solo buscan poner parches al viejo paradigma, todavía dominante, “de la visita de las obras”.
The Impact of Early Algebra: Results from a Longitudinal Intervention
Authors: Brizuela Barbara M , Martinez Mara V , Cayton-Hodges Gabrielle A
Published: November 2023

In this paper, we provide evidence of the impact of early algebra (EA) over time. We document this impact in the following ways: (a) by showing the performance over time of an experimental group of 15 children on an algebra assessment, from 3rd to 5th grade; and (b) by showing how the performance on an algebra assessment of children from an experimental group differs from the performance of a group of comparison students from their same elementary school who did not receive EA instruction from 3rd to 5th grade. We compared students’ scores through comparisons of means, correspondence factorial analyses, and hierarchical analyses. Our results highlight the positive impact of an early access to algebra, indicating that this early access is associated, when we compare 3rd graders to 5th graders, with increased scores on items that involve inequalities and graphs. When comparing experimental to comparison-group students we find increased scores on items that involve variables, functional relations, intra-mathematical contexts, tables, and algebraic expressions. The study adds to a body of literature that has been arguing for EA as well as a need to thread algebra throughout the mathematics curriculum, starting in the earliest grades.
Workplace Mathematics Research: Reflections on Personal Practical Experiences
Authors: Naresh Nirmala , Chahine Iman
Published: November 2023

This article describes our transitions through three phases of a reflective cycle as a journey from the past to the future. In the descriptive phase, we delve into our past research experiences and address questions such as: What is the role of mathematics at work? In doing so, we uncovered additional venues for exploration that called for a new mode of analysis. We transition into a theory-building phase where we share our learning experiences that occurred in-the-moment. We then shift to an action oriented (reflexive) phase during which we construe personal practical theories that enable us to negotiate broader understandings of the role of mathematics at work and identify areas for future inquiry. We document our lived experiences as informed and inspired by our work with two groups of workers - bus conductors and street vendors.
A Case Study on Pre-Service Teacher Students’ Interaction with Graphical Artefacts
Authors: Olande Oduor
Published: November 2023

This study reports from a pre-service teacher’s online learning and assessment activity on determining variability of two graphical artefacts. Using a critical-analytical perspective to data, the present study indicate that the prospective teachers surveyed showed awareness of relevant subject specific operators and methods however, these seem not be well coordinated and were submerged in forms of expressions characterized by intuitive methods and everyday language. Significantly the prospective teachers seemed to substitute statistical and mathematical methods with explanatory metaphors which while providing room for deeper subject specific engagement were however, only used superficially. Their reliance on everyday forms of expression and visual perception is perceive as a factor that might have hampered their effective choice and application of relevant subject specific tools and forms of expression. This observation puts to task the role of informal methods in statistics education.
Predictors of Achievement When Virtual Manipulatives are Used for Mathematics Instruction
Authors: Moyer-Packenham Patricia S. , Baker Joseph , Westenskow Arla , Anderson Katie L. , Shumway Jessica F. , Jordan Kerry E.
Published: November 2023

The purpose of this study was to determine variables that predict performance when virtual manipulatives are used for mathematics instruction. This study included the following quasi-experimental design features: 1) a large number of students (N=350); 2) within-class random-assignment to treatment groups; 3) retention effects measured by post-test and delayed post-test; 4) fidelity of instructional treatments documented through observations; and, 5) instrument development for the unit of study. This design was used to determine variables that predict student performance on tests of fraction knowledge for third- and fourth-grade students in two treatment groups: classroom instruction using texts and physical manipulatives (CI), and computer lab instruction using virtual fraction applets (VM). The Pre-test, Post-test 1, and Post-test 2 measured learning and retention of fraction concepts. Observation ethograms documented representation use. The results revealed that fewer demographic predictors of student performance (e.g., socio-economic status, English language learner status, and gender) exist during fraction instruction when virtual manipulatives were used. When instructors used virtual manipulatives, there was an equalizing effect on achievement in third and fourth grade classrooms, in that fewer demographic factors were influential for VM groups compared to CI groups.
Students' Misconceptions About Hypothesis Test
Authors: Krishnan Saras , Idris Noraini
Published: November 2023

Students’ misconceptions about hypothesis test have been discussed for decades by many researchers in the developed countries. However, documented studies in the non-developed countries are lacking. The purpose of this study is to fill the gap by identifying misconceptions about hypothesis test made by students in the higher education institutions in a developing country. Descriptive analysis namely percentages and pie charts have been used to analyze students’ responses to open-ended items. The misconceptions identified in this study are similar to those discussed in earlier literature implying that students in different educational settings are prone to similar misconceptions about hypothesis test.
Overcoming Gender Stereotypes & Improving Learning through the Participation of the "Other Women" in Schools
Authors: Garcia Carme , Larena Rosa , Miró Isabel
Published: November 2023

This article presents the results of research on how the daily participation of the "Other Women" women without an academic background or from cultural and ethnic minorities contributes to overcoming sexist stereotypes. The study demonstrates that their participation in instrumental learning activities transforms stereotypical beliefs about the skills of women without academic education, immigrant women, or those from cultural minorities. It can also be observed that their participation in decision-making spaces and in learning activities promotes student learning. In short, this study demonstrates that we need to include the "Other Women" into our diverse schools to progress towards the achievement of gender equity in education and society, and to create more positive learning experiences for all children.
El recurso al debate público en los procesos de reforma educativa: análisis de la experiencia española (1969-2012)
Authors: Tiana Alejandro
Published: November 2023

En las últimas décadas estamos asistiendo a un cambio significativo en el modo de construcción de las políticas públicas. El proceso, que se caracteriza por la creciente intervención de los ciudadanos en la formación de políticas, afecta a campos muy diversos de actividad, la educación entre ellos. Una de las principales novedades consiste en el recurso al debate público como instrumento para la identificación de los problemas y la formulación de posibles soluciones. Si en el ámbito internacional contamos con ejemplos relevantes, también en España se han desarrollado diversas experiencias de debate público con carácter previo al lanzamiento de reformas educativas. El artículo pasa revista a dichas prácticas, reflexionando acerca de sus características y las condiciones que deberían cumplir este tipo de iniciativas. Tomando como punto de partida la elaboración del Libro Blanco de 1969, se analizan los debates impulsados en torno a la elaboración de la Ley Orgánica de Ordenación General del Sistema Educativo (LOGSE) en 1990 y la Ley Orgánica de Educación (LOE) en 2006.
Social Justice Teacher Activism and Social Movement Unionism: Tensions, Synergies, and Space
Authors: Weiner Lois
Published: November 2023

Though the titles and acronyms of policies differ from one country to another, throughout the world a political project has taken root with the assumption that to reduce poverty and inequality, governments should privatize school systems, alter teaching from a career to contract labor, use standardized tests to make students and teachers accountable, and curtail the power and legal rights of teachers unions. This article explores how teacher activists might help reverse neoliberal educational politics by developing mutually-respectful collaborations among teachers, parents and youth in poor communities, in school-based and system-wide partnerships that involve teachers unions. Analyzing events as they were experienced and influenced by a New York City-based NGO of teachers committed to educational justice, the author examines the landscape of educational reform politics and the creation of new spaces and organizational forms not confined by collective bargaining jurisdictions and traditional bargaining demands. The study suggests that development of a social movement of teachers that might edge teachers unions in the direction of social movement teacher unionism may not occur in a linear fashion. Rather, a complex push-pull dynamic occurs with each change, opening and retracting space, remaking networks and influencing longstanding personal ties among activists.
School Choice and Inequality in Educational Decisions
Authors: Farias Mauricio
Published: November 2023

School choice has been growing all over the world. However, despite the strong implications school choice could have on future opportunities, the understanding of the mechanisms underlying the school decisions are still not clear. Based on elements from different theories, this paper study factors related with a school- track choice. The study takes advantage of extensive administrative records, national tests, and an ad-hoc survey from Chile, a country with more than 30 years with an educational system based on choice. Results suggest that socioeconomic status, cultural values, the pressure of the environment, parents’ expectations, and self-perception are correlated with the school-track choice. Results suggest that the concept of equality of opportunities in an educational system based on choice should also consider equality in the capacity for taking these decisions

Authors: Suárez-Orozco Marcelo
Published: November 2023

Este artículo examina la crisis de 2014 de los menores no acompañados procedentes de América Central y detenidos en la frontera sur de los Estados Unidos. La violencia estructural de guerra que existe en el mundo, la distopia del entorno y las crecientes desigualdades globales se encuentran detrás del mayor desplazamiento humano existente desde la Segunda Guerra Mundial. Pero la catástrofe en la frontera de los Estados Unidos responde a procesos hemisféricos únicos con historias transnacionales profundas que conectan Estados Unidos con América Latina. Este artículo analiza las desigualdades estructurales, el narco-terror, los desastres y otras variables a nivel de familia en el proceso del actual éxodo de América Central. Los datos pertenecientes al UCLA’s Institute for Immigration, Globalization and Education en -- http://icy.gseis.ucla.edu/, una de las mayores bases de datos interdisciplinar, comparativa y longitudinal sobre inmigración y familia, ayuda a explicar el porque aunque el número de menores no acompañados procedentes de México continua disminuyendo, el de niños y niñas no acompañados de América Central ha alcanzado números sin precedentes. Separados en el pasado, los niños y niñas de América Central buscan en el presente la reunificación familiar.

A Mysterious European Threesome: Work-care Regimes, Policies and Gender
Authors: Torres Anália , Coelho Bernardo , Cardoso InÃªs , Brites Rui
Published: November 2023

Arguing that European family lives are affected by many societal factors, this article discusses the interplay between three sets of phenomena: the management of work and care responsibilities, work-care policies and regimes, and gender order within the family context.Based on discussions about orientations to work and care, we compare European countries and analyze regularities and singularities among them. Identifying and assessing the interplay between structural, institutional and cultural determinants of orientations we try to explain country diversity mobilizing data from the European Social Survey (rounds 2002, 2004 and 2006) and data from Eurobarometer 2003.The paper is organized around three analytical axes. First, we analyze how work and family orientations are perceived by the Europeans. Secondly, we assess different European political policies regarding work and care arrangements, the outcome being a proposal for a work-care political typology. And finally we discuss the connections between those policies and the production or reproduction of gender order within the family.We conclude that in countries with more egalitarian gender values and policies targeted at work-care arrangements, individuals experience less work-family conflict. Conversely, in countries with more traditional gender values and restricted or disadvantaged policies we found more family-work conflict. But institutional constraints don’t act alone: orientations to work and care differ according to age, education, family forms and employment status.
The local institutionalization of accountability in education:

Accountability policies have become more important in the educational sector over the last two decades. Arguing that these policies focus increasingly on the technical core, some scholars have recently challenged the enduring finding that classroom activities and teachers’ practices are largely decoupled from their institutional environment. In this paper, we argue that this discussion could be enriched by taking into account the processes through which accountability policies are developed and implemented. Two contrasted processes of construction and implementation are comparedregarding the extent to which they have an impact on the level of decoupling between the formal structure of evaluation and the teachers’ practices. The results show that compared to the bureaucratic approach to educational reform, the network model of organizing is more favourable to the emergence of social and cognitive changes, which contribute to reduce the level of decoupling between the evaluation’s mechanism and the teachers’ practices.
How should we teach diverse students?: Critical race approach to explore diversity issues in the US K-12 schools
Authors: Shimomura Fuyu
Published: November 2023

Given the increasing trend of student diversity, assuring equitable educational access and environments have become an impending issue in the US K-12 schools. As race has been a huge determinant of the equal educational access for long time, this paper explores how the race influences the educational equity in the school building. The paper also addresses the issue of teacher quality; how would it be possible to educate teachers that know how to teach racially, linguistically and socioeconomically diverse student populations.
Competitividad, competencias y fin del ciclo fordista
Authors: Brunet Ignasi , BÃ¶cker Zavaro Rafael
Published: November 2023

Este artículo expone cómo la nueva filosofía de dirección y gestión por competencias ha puesto en duda el valor de las cualificaciones académicas a la hora de predecir el desempeño laboral, y esto se debe a la emergencia de nuevos criterios de gestión que se han fraguado con las transformaciones estructurales y organizativas que el capitalismo ha experimentado en las últimas décadas. Transformaciones que han supuesto un giro fundamental desde la dirección por tareas hacia la gestión por resultados y competencias.
Factors Affecting the Distribution of Information and Communication Technologies in an Egyptian Public University: A Case Study of the Faculty of Education at Ain Shams University
Authors: Amin Nivien Zakaria
Published: November 2023

Abstract: This research investigates the three main factors that affect the provision, access, and distribution of Information and Communication Technologies (ICT) among senior and junior faculty members in the Faculty of Education at Ain Shams University. These three factors include laws and regulations organizing the procurement of ICT in public universities in general and in the Faculty in particular, the organizational structure of the Faculty, in which the position of ICT can be determined, and the administrative and decision-making mechanisms that help distribute ICT across the departments of the faculty and the determinants that govern the execution of decisions related to ICT. The study conducted interviews with the dean (provost) of the faculty, the three vice-deans (vice-provosts) and seventeen heads of faculty departments and secretaries. The study revealed that the current elected faculty administration has shown real progress. After the election of the new administration, distribution of technologies was carried out according to new demands that priority should be given to departments that had not gotten equipment in the previous year. Under the elected administration, the storekeeper himself calls the departments and informs their secretaries that the shipment of ICT is ready for distribution according to the needs of the departments.
A denotationally-based program logic for higher-order store
Authors: Aagaard Frederik Lerbjerg , Sterling Jonathan , Birkedal Lars
Published: November 2023

Separation logic is used to reason locally about stateful programs. State of the art program logics for higher-order store are usually built on top of untyped operational semantics, in part because traditional denotational methods have struggled to simultaneously account for general references and parametric polymorphism. The recent discovery of simple denotational semantics for general references and polymorphism in synthetic guarded domain theory has enabled us to develop TULIP, a higher-order separation logic over the typed equational theory of higher-order store for a monadic version of System F{mu,ref}. The Tulip logic differs from operationally-based program logics in two ways: predicates range over the meanings of typed terms rather than over the raw code of untyped terms, and they are automatically invariant under the equational congruence of higher-order store, which applies even underneath a binder. As a result, "pure" proof steps that conventionally require focusing the Hoare triple on an operational redex are replaced by a simple equational rewrite in Tulip. We have evaluated Tulip against standard examples involving linked lists in the heap, comparing our abstract equational reasoning with more familiar operational-style reasoning. Our main result is the soundness of Tulip, which we establish by constructing a BI-hyperdoctrine over the denotational semantics of F{mu,ref} in an impredicative version of synthetic guarded domain theory.

Dynamic Separation Logic
Authors: de Boer Frank S. , Hiep Hans-Dieter A. , de Gouw Stijn
Published: November 2023

This paper introduces a dynamic logic extension of separation logic. The assertion language of separation logic is extended with modalities for the five types of the basic instructions of separation logic: simple assignment, look-up, mutation, allocation, and de-allocation. The main novelty of the resulting dynamic logic is that it allows to combine different approaches to resolving these modalities. One such approach is based on the standard weakest precondition calculus of separation logic. The other approach introduced in this paper provides a novel alternative formalization in the proposed dynamic logic extension of separation logic. The soundness and completeness of this axiomatization has been formalized in the Coq theorem prover.
A Language for Evaluating Derivatives of Functionals Using Automatic Differentiation
Authors: Di Gianantonio Pietro , Edalat Abbas , Gutin Ran
Published: November 2023

We present a simple functional programming language, called Dual PCF, that implements forward mode automatic differentiation using dual numbers in the framework of exact real number computation. The main new feature of this language is the ability to evaluate correctly up to the precision specified by the user -- in a simple and direct way -- the directional derivative of functionals as well as first order functions. In contrast to other comparable languages, Dual PCF also includes the recursive operator for defining functions and functionals. We provide a wide range of examples of Lipschitz functions and functionals that can be defined in Dual PCF. We use domain theory both to give a denotational semantics to the language and to prove the correctness of the new derivative operator using logical relations. To be able to differentiate functionals -- including on function spaces equipped with their compact-open topology that do not admit a norm -- we develop a domain-theoretic directional derivative that is Scott continuous and extends Clarke's subgradient of real-valued locally Lipschitz maps on Banach spaces to real-valued continuous maps on Hausdorff topological vector spaces. Finally, we show that we can express arbitrary computable linear functionals in Dual PCF.
