Medical liability claims in gynaecologic care: retrospective analysis of claims related to gynaecology in the Netherlands (2005–2022) – Is there a connection between treatment indication, phase of treatment and the risk of medical malpractice claims?
Authors: Klemann Désirée , Hoopen Rankie ten , Mertens Helen , van Merode Frits
Published: November 2024

Background

An increased interest in medical liability claims has been noticed. Nevertheless, detailed data on subject of claims and possible factors that contribute to litigation and indemnity payments are scarce and relatively dated. Insight into these data may provide valuable information to prevent both incidents and malpractice claims.

Objective

To analyse the subject, outcome and costs of malpractice claims related to gynaecological care and their connection with treatment indications and treatment phases.

Design

A retrospective analysis of malpractice claims related to gynaecology.

Setting

All claims related to gynaecology, filed and closed by Netherlands’ largest liability insurance company, Centramed between 2005 and 2022.

Sample

N = 382.

Methods

An in-depth analysis of claim files was performed.

Results

A total of 68.6% of the claims were related to perioperative incidents. A total of 88.0% of all claims were related to treatments with a benign indication and only 12.0% were related to malignancies. The share of malignant treatment indications was high for claims related to diagnostic incidents (37.9%), compared to 7.3% for claims related to surgical treatment. Liability was accepted in 22.5% of all claims. The total costs of all claims amount €6,6mlj. Besides the indication for treatment, deficient expectation management (a lack of informed consent) contributes to dissatisfaction and increases the risk of malpractice claims. Finally, an inadequate medical file compromises legal defence and influences the judgement and settlement of malpractice claims.

Conclusions

There is a connection between treatment indications and treatment phases and the risk of malpractice claims and their outcome.
Survey of Massachusetts peer recovery coaches’ attitudes toward the use of psychedelics to treat substance use disorders
Authors: Szpak Veronica , Kim Amanda , Sager Zachary , Suzuki Joji
Published: November 2024

Background

There has been a growing interest in the use of psychedelics for therapeutic purposes. However, there is a lack of research on peer recovery coaches' attitudes toward the use of psychedelics for SUD treatment. Therefore, we conducted a survey of peer recovery coaches in Massachusetts to gain insight into their attitudes toward the use of psychedelics to treat SUDs.

Methods

Peer recovery coaches in Massachusetts were invited to participate in an online survey between August and October 2023. The survey collected respondents’ demographics, socioeconomic characteristics, personal substance use history, opinions on psychedelics for addiction treatment, and spiritual experiences.

Results

146 individuals completed the survey. The mean age was 48.7 years (SD 11.2), 61% identified as female, 74% were employed as peer recovery coaches, and 43% were Certified Addiction Recovery Coaches (CARC). 70.7% reported utilizing 12-step programs, and 76% reported having a personal history of using psychedelics. The majority of participants agreed that they would feel comfortable being a coach for someone using psychedelics to treat SUDs. However, a significant number of participants expressed concerns. Those who had utilized 12-steps were more likely to express concerns about the dangers of using psychedelics to treat SUD. Conversely, participants with a personal history of psychedelic use were more likely to support the use of psychedelics for the treatment of SUDs.

Conclusions

While peer recovery coaches express support for using psychedelics to treat SUD, they also voice concerns about the potential risks.
Probiotics and eating disorders: a systematic review of humans and animal model studies
Authors: Bahari Hossein , Akhgarjand Camellia , Mirmohammadali Seyedeh Nooshan , Malekahmadi Mahsa
Published: November 2024

Background

Eating disorders are complex mental health conditions that significantly impact physical and mental well-being. Current research suggests a potential link between eating disorders and the gut microbiota, highlighting the role of gut-brain communication and its influence on nutrient absorption. Probiotics, which are beneficial bacteria, have shown promise in modulating the gut microbiota and may offer complementary interventions in the treatment of eating disorders.

Methods

A comprehensive search was conducted in electronic databases, including PubMed/Medline, Scopus, and Web of Science, from inception to January 2024 to analyze the existing literature on the effects of probiotic supplementation in eating disorders. The search strategy included terms related to probiotics, prebiotics, eating disorders, and food addiction. The human studies were assessed for risk of bias using the Cochrane tool. The quality of animal studies was evaluated using the risk of bias (RoB) tool from the Systematic Review Centre for Laboratory Animal Experimentation.

Results

Of the 417 papers, 12 eligible studies were included comprising five animal and seven clinical studies. Clinical trials ranged from 10 to 20 weeks and were randomized and parallel-arm design. The included studies varied in terms of sample characteristics, intervention types, and outcome measures. Preliminary findings suggest that probiotics may influence gut microbiota composition and may offer support in the treatment of eating disorders.

Conclusions

The reviewed studies showed that probiotic supplementation may have a role in reducing food addiction and binge eating, and enhancing satiety, regulating food intake as well as positively affecting mood. However, further studies with better quality and larger sample size are needed to further validate these findings.
Rapid-repeat time-lapse vertical seismic profile imaging of CO2 injection
Authors: Cai Xiaohui , Hu Qi , Innanen Kristopher A. , Keating Scott D. , Eaid Matthew V. , Macquet Marie , Lawton Donald C.
Published: November 2024

In a carbon capture and storage (CCS) project, monitoring CO2 during the injection period is crucial for ensuring the safety and effectiveness of the injection process. The real-time observation of CO2 behavior allows for adjustments to the injection parameters to enhance performance and enables the refinement of the reservoir simulation models to predict plume migration accurately. Achieving this with seismic surveys requires significantly shorter intervals between the surveys compared with the conventional monthly or yearly timescales. This study aims to identify an effective seismic monitoring method, encompassing acquisition design and an imaging technique, for capturing the short-term, dynamic subsurface changes resulting from CO2 injection. We present images generated through elastic full-waveform inversion applied to rapidly repeated time-lapse vertical seismic profile (VSP) field data. The data are acquired using a fixed source shooting across an injection plume at approximately 15 min intervals over several days. These images, created from a combination of sparse geophone data and densely distributed acoustic sensing (DAS) data, provide clear snapshots of transient subsurface changes near the injection well. The results are further validated using a synthetic inversion experiment, demonstrating that the combined geophone and DAS-VSP approach offers a cost-effective and informative monitoring solution for CCS projects.
Machine-learning-driven semiauto multiscenario horizon interpretation with uncertainty quantification

Published: November 2024

Horizon interpretation is one of the most labor-intensive and interpreter-dependent processes in the reservoir characterization workflow. This issue becomes critical, particularly when the quality of a seismic reflector is poor. The uncertainty caused by inaccurate seismic horizon interpretations often misleads the volumetric analyses of subsurface reservoirs. To resolve these issues, we develop a four-step machine-learning-based semiautomated horizon interpretation workflow. In the first step, we generate multiple virtual stratigraphic labels. We then generate multiple synthetic data points to mimic the features of field data by applying a cycle-consistent generative adversarial network. In the third step, we train a U-Net augmented with feature pyramid attention and a convolutional block attention module on the synthetic data set. Finally, the probabilistic distribution results are used to obtain multiple horizon selection scenarios, yielding various possible stratigraphic results. As our method yields a probability distribution rather than a single value for a given field data and seed point, we can obtain multiple possible horizon scenarios rather than a single horizon. Through uncertainty quantification, we can select an appropriate horizon among multiple scenarios. We apply our method to the Smeaheia field data set, which is characterized by numerous and large faults, and compare the results with reference interpretation to confirm its accuracy. The field data example indicates that our method can be applied to complex geologic structures.

Published: November 2024

PURPOSE

Alkylating agents (ALKY) are the main chemotherapies used for advanced neuroendocrine tumors (NETs). O
6
-Methylguanine-DNA methyltransferase (MGMT) status, as proficient (p) or deficient (d), may predict the response to ALKY.

PATIENTS AND METHODS

MGMT-NET (ClinicalTrials.gov identifier:
NCT03217097
) was a phase II trial randomly assigning 1:1 for pMGMT or 2:1 for dMGMT-NETs to either ALKY or oxaliplatin (Ox). Inclusion criteria were a confirmed advanced pancreatic, thoracic, or unknown primary NETs with an indication for chemotherapy and tissue available. The primary aim was to detect a difference of 35% between the 3-month objective response rate (ORR) in pMGMT-NETs versus in dMGMT-NETs when treated with ALKY. A biomarker-stratified design was performed to compare ALKY and Ox in the dMGMT and pMGMT strata for the secondary end points. dMGMT was defined using pyrosequencing (PSQ; methylated
MGMT
≥9%) and using immunochemistry (
H
-score of MGMT <50) when PSQ was not interpretable.

RESULTS

From October 2018 to October 2021, 105 patients (55 pancreas, 38 thorax, 12 unknown) started either ALKY (n = 62) or Ox (n = 43). The median age was 63 years (range, 30-84), and 59% were males. NETs were G1 (19%), G2 (69%), or G3 (10%). Among patients with interpretable MGMT status, 56.9% (58 of 102) had a dMGMT-NET. The primary end point was not reached; the 3-month ORR was 10 (29.4%) versus 2 (8%), and the odds ratio was 3.5 (0.58-21.16),
P
= .172. However, best ORR (18 [52.9%]
v
3 [11.5%]) and median progression-free survival (14.6 [95% CI, 7.2 to 22.1]
v
11.3 [9.4 to 13.2] months) were higher for dMGMT-NETs versus pMGMT-NETs. MGMT status does not seem to affect the Ox efficacy.

CONCLUSION

Despite the fact that the primary end point was not reached, ALKY has clinical activity in patients with dMGMT-NETs.
Amiri Baraka's Humanist Theater: A Reading of A Black Mass
Authors: Fitzgerald Jason
Published: November 2024

This essay articulates Amiri Baraka's relationship to humanist universalism through his work as a theatermaker, in particular through his play A Black Mass. Baraka's Black nationalist writings are infused with humanist assumptions despite the apparent contradiction between humanist universalism and nationalist separatism. The essay nominates as poietic the form of humanism that Baraka values, meaning that, for Baraka, humans imagine new worlds into existence from materials taken by the world as it is. This poietic humanism values contingency, invention, and impermanence and refuses essentialisms. The essay begins by drawing from Baraka's essays on theater the claim that the work, or action, of revolutionary art is to set into motion a doubling, to produce oppositions that remain unsettled. Next is an extended reading of Baraka's play A Black Mass, first staged in New Jersey in 1966, which he uses to settle philosophical scores with the Nation of Islam. Although the play borrows its plot from the Nation of Islam's myth of Yakub, which casts the white race as fundamentally monstrous, A Black Mass resists a vision of history as racial destiny. It does so, first, by staging the production of the human as a category of exclusion and so critiquing the process of racialization, and second, by rooting its tragic plot structure in a break between the expressive self and the poietic community. The essay's conclusion briefly contextualizes Baraka's poietic humanism within late 1960s debates among nationalist and Negritude thinkers, suggesting Frantz Fanon as an important influence and reasserting a dynamic approach to racial difference in Baraka's vision of Black art.
Unfolding Memory in Adil Hasan's When Abba Was Ill
Authors: Bhattacharya Sreerupa
Published: November 2024

Adil Hasan's When Abba Was Ill stages the aesthetic and ethical tension involved in representations of illness and death. This article aims at parsing through the strategies employed in publishing what was meant to be a private record of the six months during which Hasan's family came to terms with the diagnosis of his father's cancer. On one hand, the article reflects on how the genre of the photobook affords the intimacy of encounter that such a project demands, and on the other, it demonstrates how Hasan's work oscillates between provoking and resisting the reader's identification with the photographs. While the photobook's title promises a retrospective account of the period, this article argues that the book emerges as eventually undercutting its own project. Even as it enacts the script of recollection, the photobook tends to obfuscate the memory of the time by blocking it, deferring its appearance, and ultimately rendering it opaque for readers.
Humanism in China (Zhongguo renben) and Recontextualizations of Chinese Documentary Photography
Authors: Spyra Bernd , Hilscher Sanja
Published: November 2024

Considered the first large-scale presentation of contemporary documentary photography by a Chinese institution, the traveling exhibition Humanism in China (Zhongguo renben) was documented through the publication of at least three separate photobooks, each addressing distinct domestic and international audiences in mainland China (2003), Germany (2006), and the United States (2009). These photobooks preserve curatorial choices made at the different stations of the exhibition regarding nature, number, and layout of photos in order to adapt to different audiences in China and abroad. Among these choices, the inclusion of historical, posed propaganda photos in the corpus of documentary photos, as well as the removal of eleven photos from the international editions of the photobook—allowing the transformation of the project from a critical appeal for reform into an element of official Chinese cultural diplomacy—makes different Chinese representational systems visible. Analytically, recognizing the signifiers of these systems opens new ways to investigate the photobooks, their distinct curatorial choices, and underlying conceptions of (inter)national representations of China.

Published: November 2024

Open microsurgical and endovascular techniques are the 2 primary strategies for treating intracranial aneurysms. Microsurgical clipping and adjuvant technical maneuvers are well-established techniques with a track record for high occlusion rates and durable repairs. Endovascular, endosaccular, and extrasaccular therapies are associated with lower peri-procedural morbidity but with generally higher rates of retreatment. We discuss key clinical and anatomic considerations in treatment decision-making and compare the risks and benefits of microsurgical vs endovascular treatment within each context.

Published: November 2024

BACKGROUND AND OBJECTIVE:

Iatrogenic spinal durotomies occur at a rate of 1% to 17%. Surgical simulation for durotomy repair is needed to provide affordable, accessible, and validated practice. This study sought to design and validate a simple 3-dimensional printed model for spinal cerebrospinal fluid (CSF) leak repair and to introduce the Rochester original objective structured assessment of technical skills (OSATS) CSF leak (ROCL) repair criteria for assessment.

METHODS:

A spinal model was designed to mimic a lumbar laminectomy with the L3-5 lamina removed and 3-dimensional printed using Vero polymers. The model was paired with a porcine collagen “dura” that was pressurized using IV saline and overlayed with gel-molded fascial, muscle, and skin layers with an opening. Participants were provided a training model with a 1.5-cm midline durotomy, surgical microinstrument set, microscope, and 6-0 prolene suture. The 25-point ROCL repair criteria were adapted from the original OSATS principles to assess proficiency in surgical repair by 2 blinded neurosurgeons not participating in the trials. Postsimulation survey data regarding model realism were collected.

RESULTS:

Six residents and 4 attendings participated. Median operative time in minutes was 13 minutes among residents and 7 minutes among attendings. Moreover, the ROCL score was a median of 19/25 for attendings and 15/25 for residents. The suture angle was statistically more consistent among senior residents and attendings compared with junior residents. Participants agreed that the model was realistic (median 4/5), useful for improving the operative technique (median 5/5), and would increase comfort in spinal CSF leak repair procedures (median 5/5). Each reusable model had a cost of $19.99 if printed with polylactic acid and each replacement dura cost <3¢.

CONCLUSION:

This study presents an affordable, realistic, and educational spinal CSF leak repair model and introduces ROCL for assessment.
Multicenter Randomized Controlled Clinical Trial to Compare the Safety and Performance of Two Bone Flap Fixation Systems
Authors: Gómez de la Riva Álvaro , Rico Marta , Voršič Matjaz , Rokavec Valentin , Asencio-Cortés Carlos , Muñoz-Hernández Fernando
Published: November 2024

BACKGROUND AND OBJECTIVES:

Polymeric clamp-like devices present potential advantages regarding plates and screws to close craniotomies; however, no clinical research has provided enough evidence to compare them. This randomized controlled trial compares the clinical safety and performance of clamp-like devices with the standard of care for craniotomy closure: titanium plates and screws (P&S).

METHODS:

A prospective, double-arm, multicenter randomized controlled trial was performed at 3 sites, recruiting 60 patients undergoing neurosurgical interventions requiring craniotomy. Patients were randomly allocated to 2 groups depending on the bone flap fixation system to be used: plates and screws (any brand) and clamp-like devices (Cranial LOOP, NEOS Surgery S.L.). The primary end point of the study (bone flap alignment) was assessed 6 months after surgery through neuroimaging. Secondary end points included adverse events and device deficiency assessment, closure method usability assessed by the surgeon, and patient-reported device-related inconveniences.

RESULTS:

It was necessary to use a median of 3 Cranial LOOP and 4 plates and 8 screws to close craniotomies. All patients from both groups had equally good bone flap alignment. Most implantations were reported as easy or very easy for both groups, and surgeons were generally satisfied or very satisfied with both treatments. No related adverse events have been reported for any of the treatment groups. Two patients reported discomfort or protuberances caused by P&S; no inconveniences were reported for Cranial LOOP.

CONCLUSION:

Cranial LOOP performance is equal to P&S for fixation of the cranial bone flap. In addition, it presents some advantages, such as the use of a lower number of devices, potentially making this system more affordable, and the lack of discomfort previously linked with the use of P&S.

Published: November 2024

O presente trabalho busca analisar a disciplina jurídica da aprovação tácita dos atos de liberação de atividades econômicas (efeitos positivos do silêncio administrativo), à luz da Lei de Liberdade Econômica (Lei nº 13.874/2019) e do seu regulamento (Decreto nº 10.178/2019). Examinam-se, primeiramente, os requisitos legais para sua obtenção. Demonstra-se, em seguida, que exceções à regra geral de aprovação tácita só podem ser criadas por lei formal. Na sequência, vê-se que a completude instrutória exigida para deflagrar a contagem do prazo para análise do pleito é requisito estritamente formal, não devendo-se adentrar no mérito dos documentos apresentados. Por fim, o decurso do prazo fixado sem decisão da autoridade competente gera para o interessado o direito a documento (meramente) declaratório da liberação da atividade econômica.
Tipología de conflictos ambientales
Authors: Kaufmann Christoph Josef , Prieto-Ríos Enrique
Published: November 2024

En este escrito se propone, entonces, elaborar una tipología de conflictos ambientales en Latinoamérica. Por medio de ejemplos de conflictos ambientales de distintos países, se demuestra cómo los conflictos ambientales se basan y reproducen desigualdades sistémicas que se articulan mediante la marginación y la criminalización de quienes reclaman el respeto de sus derechos en torno a la implementación, la toma de decisiones o la mitigación de impactos de dichos proyectos económicos. También se revisaron la normativa y la jurisprudencia que se han ido consolidando a nivel nacional e internacional para la resolución de conflictos ambientales, a fin de fortalecer los mecanismos de protección de la naturaleza y sus defensores y defensoras, y en pro de establecer mecanismos de participación comunitaria en la toma de decisiones sobre el uso ‘adecuado’ de los recursos. Asimismo, este escrito da cuenta de la importancia de combinar el análisis del contexto específico donde se presente un conflicto con consideraciones sistémicas, para así identificar algunos mecanismos que contribuyen a la aparición y la resolución de conflictos ambientales.

The Click-Based MNL Model: A Framework for Modeling Click Data in Assortment Optimization
Authors: Aouad Ali , Feldman Jacob , Segev Danny , Zhang Dennis J.
Published: November 2024

We introduce the click-based MNL choice model, a framework for capturing customer purchasing decisions in e-commerce settings. Specifically, we augment the classical Multinomial Logit choice model by assuming that customers only consider the items they have clicked on before they proceed to compare their random utilities. In this context, we study the resulting assortment optimization problem, where the objective is to select a subset of products, made available for purchase, to maximize the expected revenue. Our main algorithmic contribution comes in the form of a polynomial-time approximation scheme (PTAS) for this problem, showing that the optimal expected revenue can be efficiently approached within any degree of accuracy. To establish this result, we develop several technical ideas, including enumeration schemes and stochastic inequalities, which may be of broader interest. Using data from Alibaba’s online marketplace, we fit click-based MNL and latent class MNL models to historical sales and click data in a setting where the online platform recommends a personalized six-product display to each user. We propose an estimation methodology for the click-based MNL model that leverages clickstream data and machine learning classification algorithms. Our numerical results suggest that clickstream data are valuable for predicting choices and that the click-based MNL model can outperform standard logit-based models in certain settings.

Published: November 2024

This study aims to determine the needs of students in learning physics, explicitly focusing on Newton's Law. The respondents included 149 students and three physics teachers from high schools (SMA) across Malang Regency and Malang City. Respondents were selected using a random sampling technique. The research instruments used were questionnaires and interview guidelines. Data analysis was conducted qualitatively, with coding and categorization applied to the questionnaire data. Nine respondents were then selected for interviews, and the transcribed interview data were used to complement the questionnaire findings. The study found that students preferred three learning models: practical experiments, observation, and reading. In particular, 61.2% of high school students in the city favored learning through practical experiments, which began with observing Newton's Law phenomena and was reinforced by hands-on practice. Meanwhile, 45.7% of district high school students preferred learning through observation, emphasizing instructional media such as videos, physics demonstrations, and guided discussions on physics-related problems. The results of this study are expected to inform the implementation of learning methods that accommodate the specific needs identified among students.
The intersectionality of gender discrimination impact on Beth Harmon’s identity development in The Queen’s Gambit
Authors: Prasetyaningrum Dyah Ayu , Ahdiani Ulaya
Published: November 2024

The Queen's Gambit (2020) addresses gender inequality against women in male-dominated industries like chess. Queen's Gambit displays patriarchal structural and representational judgment of women. Gender discrimination affects women's careers, identities, and development. Thus, the study examines gender discrimination's intersectionality and its effects on Beth Harmon, a white low-class young woman. Pictures and talks from the series are the key data in this qualitative study. Also used are intersectionality theory to analyze gender discrimination statistics and stages of development theory to examine character identity development. Gender, age, ethnicity, class, prejudices, and appearances encountered by Beth Harmon shaped her multifaceted identity. Discrimination hindered Beth's development as a chess player and woman throughout her school years, adolescence, and young adulthood, leading to both dystonic and syntonic effects. Stereotypes and injustice give rise to discrimination; therefore, we must acknowledge various identities and histories to prevent a "double burden" of discrimination that impedes growth.

Authors: Wajiran Wajiran , Widiyanti Ana
Published: November 2024

The miniseries Self Made depicts Black women's empowerment, intersectionality, and entrepreneurship. The study examines how the series depicts Sarah Breedlove's socio-economic hardships as she overcomes racial, gender, and class oppression to become America's first self-made Black female millionaire through qualitative analysis of key scenes and dialogues. The study uses Black feminist theory and intersectionality to show how Sarah's entrepreneurial career empowers Black women by questioning beauty norms and providing economic opportunity. Analysis shows how the series criticizes racism and misogyny while glorifying resistance and communal cohesion. The analysis also highlights the series' relevance to racial and gender equality discourse in capitalist economies. The study shows how cultural representations like Self Made may drive social change and help us comprehend Black female entrepreneurs' particular obstacles by focusing on their intersectional experiences. This research advances media studies, feminist theory, and African American cultural history by demonstrating entrepreneurship's transformative capacity to empower.
Traditional symbols and social constructs in M. Irata’s Momuhuto: A literary sociology perspective
Authors: Aminudin Muhammad Fauzan , Alade Salman , Widyastuti Sri Harti , Wiyatmi Wiyatmi
Published: November 2024

This descriptive qualitative study aims to explore the traditional symbols and social constructions of Gorontalo society as reflected in M. Irata’s short story Momuhuto. Employing literary sociology perspective, the data were elicited through key quotations within the text, analyzed through document analysis. The study highlights on how the short story reflects philosophical meanings behind traditional symbols and how social norms are depicted. The results indicate that Momuhuto presents meaningful symbols – such as purification rituals – emphasizing Gorontalo society’s dedication to preserving its traditions. Despite the influence of modernization, the traditional leaders play a significant role in maintaining cultural identity and social harmony.

actitudes del profesorado ante la filosofía con o para niños/as
Authors: Miguélez vila María , Raposo rivas Manuela
Published: November 2024

El Programa de filosofía con y para niños ‘FiloHilo’ surgió de la posibilidad de trasladar desde el Prácticum a las aulas procesos de innovación y renovación pedagógica basados en el diálogo y la práctica filosófica. Son multitud los estudios que nos permiten afirmar que la Filosofía para niños/as se ha transformado en una actividad efectiva, posible y necesaria para todas las edades, ya que atiende a la necesidad propia del ser humano: la pregunta, el cuestionamiento, la duda. Pero estos procesos se instauran si hay una actitud de apertura y disposición por parte del profesorado: esa primera condición, la actitud de apertura y disposición, es sobre la que se centra este artículo y fue el germen de preguntas clave: ¿cómo percibe el profesorado estas prácticas?, ¿las conocen?, ¿las han utilizado alguna vez?, ¿tienen predisposición a su implantación?, ¿está preparado para desarrollar un pensamiento ético, reflexivo, solidario y crítico en las aulas? Con el objetivo de responder a ello, se elaboró un cuestionario compuesto por 31 ítems y 4 dimensiones, que posee altos niveles de fiabilidad (α=0.949). Fue enviado a todos los centros educativos gallegos y respondido por 167 docentes. Los resultados muestran una alta predisposición hacia la práctica filosófica, fundamentalmente, por apoyar el razonamiento crítico y la toma de conciencia. Se concluye demandando un abordaje diferente de la enseñanza de la filosofía, tomando en cuenta las necesidades y los intereses del profesorado e introduciendo la necesidad de formación en el ámbito de la práctica filosófica, entendiendo la filosofía como algo que se practica y puede transformar la vida de los alumnos y alumnas: autoconocimiento y autorrealización.
DETERIORO Y EMERGENCIA FLUVIAL, GESTIÓN DE INUNDACIONES Y EL DESAFÍO DE LA RESTAURACIÓN HIDROMORFOLÓGICA
Authors: Ollero Alfredo
Published: November 2024

Como ejemplo relevante de geografía física crítica se abordan los graves problemas fluviales generados por el capitalismo, que ha llevado a los ríos a altos y generalizados niveles de deterioro y a una situación actual de emergencia marcada por el estrechamiento y la incisión de los cauces. En este contexto, las presas y embalses constituyen el ejemplo máximo de destrucción fluvial. A pesar de las dificultades para vencer inercias tradicionales y falsos mitos, se va trabajando, desde una geografía crítica y activista, en un cambio de paradigma en dos grandes líneas interrelacionadas: en la sustitución del actual sistema de lucha contra las inundaciones, dañino y obsoleto, por nuevas iniciativas de gestión basadas en la naturaleza, y en la restauración hidromorfológica como herramienta y trayectoria para recuperar a los ríos de los impactos sufridos en el Antropoceno. Estos dos grandes desafíos solo podrán lograrse y extenderse con apoyo social y político, por lo que la geografía y la educación ambiental seguirán siendo fundamentales en el logro de territorios fluviales resilientes con salud fluvial para la salud de las personas.
BASES TEÓRICAS SOBRE A PRODUÇÃO IMOBILIÁRIA
Authors: Rodrigues Arlete Moysés
Published: November 2024

A crítica da economia política da cidade, da urbanização e do espaço, instiga-nos a entender que a urbanização se caracteriza por um processo que delimita, define e expande atividades econômicas, sociais e políticas. As atividades criam, alteram, recriam e modificam a vida cotidiana; produzem riquezas que são desigualmente distribuídas no espaço e na sociedade. Tais riquezas, produzidas pelo trabalho, são acessadas pelas diferentes frações de classes sociais que compõem o capitalismo a partir da capacidade de pagar, portanto, mediadas pelo dinheiro, outra categoria de análise importante para desvendar a economia política.

PROJETO “PORTO MARAVILHA” NO RIO DE JANEIRO
Authors: Ferreira Alvaro , Pizzolante Horácio , Viriato Siniscalchi Mateus
Published: November 2024

O projeto “Porto Maravilha” foi lançado em 2009. Aproximadamente 15 anos após seu lançamento, é possível afirmar que sob a orientação das parcerias público-privadas, de evidente cunho neoliberal, as estratégias políticas do Estado se articulam às estratégias econômicas do capital financeiro-imobiliário, erguendo variados entraves territoriais para muitos dos usos e apropriações possíveis do espaço. Muito do que tem sido proposto e posto em prática no Projeto Porto Maravilha foi inspirado nas transformações realizadas em Barcelona principalmente no último quartil do século XX. O desenvolvimento do artigo segue um caminho metodológico que faz uso da tríade formada pelos processos materialização, substrução e projeção – por nós desenvolvida em trabalhos anteriores – para pensar as reformas urbanas das cidades. Esta ferramenta analítica nos permite compreender a produção alienadora do espaço e da vida cotidiana, somando ao estudo das representações e dos jogos de poder a análise das construções da materialidade e da(s) ideologia(s) vividas, percebidas e concebidas.
PAISAJES DE LA DESPOSESIÓN: ESCENAS METROPOLITANAS
Authors: Benach Núria
Published: November 2024

Desde la primera globalización y la era de los "descubrimientos", la acumulación capitalista ha recurrido a espacios “no capitalistas”, sometiéndolos económica, social y culturalmente, y configurando espacios coloniales. En este trabajo buscamos mostrar cómo ese mecanismo fundamental —el de aprovechar espacios aparentemente ajenos a la lógica del capital— no fue exclusivo de la época colonial o del imperialismo, sino que sigue operando hoy bajo el capitalismo neoliberal, manifestándose a todas las escalas, incluso en los espacios metropolitanos. En estos, los espacios centrales, donde se concentran las inversiones y las mayores oportunidades de acumulación, explotan los espacios periféricos, desplazando actividades y residentes no deseados en el centro.
Se argumenta que el capitalismo no existiría en su forma actual sin su pasado colonial, y que los espacios centrales metropolitanos tampoco habrían alcanzado su estructura y funciones económicas actuales sin una historia de sometimiento de los espacios periféricos a sus necesidades. Para ello, se revisa la relevancia actual del concepto de acumulación primitiva, se define la noción de "paisajes de la desposesión" y se presentan algunos ejemplos de estos paisajes en áreas metropolitanas.
TERCIARIZACIÓN INDUSTRIAL A PARTIR DE LA ADOPCIÓN DE LA ECONOMÍA DEL CONOCIMIENTO EN ARGENTINA
Authors: Buffalo Luciana
Published: November 2024

Este trabajo busca comprender cómo avanza el sector terciario avanzado (conocimientos tecnológicos digitales, I+D) en la estructura productiva Argentina, sobre todo de la industria, como parte de la profunda reestructuración productiva global del sistema capitalista. 
La terciarización económica, como proceso global responde a un cambio estructural, y la tendencia es hacia una especialización productiva que demanda ahora mayor complejidad tecnológica tanto en términos materiales como inmateriales (infraestructura urbana de comunicaciones como fibra óptica, internet de alta velocidad, comunicación satelital, 5G, equipamiento informático de alto rendimiento, plataformas y sistemas digitales, selectividad de la calificación de mano de obra, I+D, entre otros). 
Diversos estudios dan cuenta de una integración creciente entre industria y servicios, con industrias cada vez más terciarizadas, que demandan servicios especializados dentro y fuera de su ámbito de producción.  
Analizar este fenómeno es relevante, en tanto el sector terciario es explicativo de una gran cantidad de actividades, y corresponde a una forma particular de división del trabajo internacional e interna en cada país. Al mismo tiempo, la expansión del sector terciario avanzado hacia adentro de las industrias, trae consigo una reorganización de las estructuras productivas, sociales y territoriales, evidenciando profundas transformaciones no solo en el sector industrial, sino también en las regiones donde este sector es relevante.
URBANIZACIÓN CONTEMPORÁNEA EN SUR DE BRASIL
Authors: Soares Paulo Roberto Rodrigues
Published: November 2024

El artículo discute la urbanización contemporánea y sus rebatimientos empíricos en una ciudad media de Sur de Brasil, la ciudad de Pelotas, estado de Rio Grande do Sul. Partimos de las conclusiones de una tesis doctoral realizada en 2002. Se trabajará los cambios en la producción espacial de la ciudad en los últimos veinte años y si las tendencias verificadas en la tesis se han confirmado. En las conclusiones de la tesis ya se demarcaban tendencias de dispersión urbana, descentralización de servicios y de fragmentación socioespacial. Dichas tendencias se han exacerbado en las décadas iniciales del siglo XXI. Nuestro análisis partirá de autores y autoras de la urbanización contemporánea para analizar los distintos movimientos de la producción espacial en la ciudad y sus nexos con procesos globales.  Lo observado en los últimos veinte años ha sido la complexificación del espacio urbano con la llegada de nuevos agentes, nuevos procesos y la producción de un espacio urbano más fragmentado y polarizado. Se destacan las urbanizaciones cerradas, además de una nueva ideología urbana, con experimentos del “nuevo urbanismo”, sin embargo, destinados a grupos sociales muy específicos. Finalmente hay que enfatizar el espacio “post-pandémico”, en la cual la decadencia del centro histórico es evidente.
