Relationship between the characteristics of Japanese physicians involved in medical care for older adults and their approaches to treating older patients with multimorbidity
Authors: Kimura Takuma , Nomura Kyoko , Hashimoto Masayoshi , Shinmura Ken
Published: June 2024

One countermeasure against the increasing prevalence of multimorbidity is the need to provide clinical education and training that considers the characteristics of physicians. We conducted a questionnaire survey to determine the relationship between physicians’ characteristics and their approach to treating older patients with multimorbidity. A total of 3300 geriatric specialists and primary care specialists in Japan were enrolled. A 4-point Likert scale was used to score the following items: difficult diseases (43 items), difficult patient backgrounds (14 items), important clinical factors (32 items), and important clinical management (32 items). Exploratory factor analysis was performed to examine the constructs in each of the scales Diseases, Backgrounds, Clinical Factors, and Clinical Management, and group comparisons by physician characteristics were conducted. A total of 778 respondents were included in the analysis. Six factors for Diseases, two factors for Patient Background, four factors for Clinical Factors, and two factors for Clinical Management were explored as patterns. Group comparison between mean scores for each factor and the characteristics of responding physicians showed statistically significant differences in at least one factor for all patterns in terms of years of experience as a physician (26 years or less, 27 years or more), the clinical setting (providing or not providing home medical care), and sex (male or female). Our results suggest a need for clinical education and training that takes into account not only physicians’ experience and clinical setting, but also their sex.
Assessment of the occurrence of the second generation of Mythimna loreyi Duponchel (Lepidoptera: Noctuidae) using temperature-dependent developmental and oviposition models
Authors: Baek Sunghoon , Kim Min-Jung , Kim Eun Young , Jung Jin Kyo , Park Chang-Gyu
Published: June 2024

A significant crop pest, Mythimna loreyi, migrates annually to Korea and has been frequently observed in rice and corn fields. However, the phenology of this pest, particularly in relation to its ecological interactions and host crop seasons in Korea, remains poorly understood. This study aims to clarify the timing of the second generation of M. loreyi in Korea to enhance pest management strategies. To achieve this, we developed temperature-dependent models for developmental and ovipositional rates, studying these processes across five constant temperatures (15, 20, 25, 30, and 35°C). Our models, which showed a high correlation with observed data (r2 ≥ 0.93), include a theoretical approach that combines the developmental variation of immatures with the necessary degree-days for 50% egg laying and complete egg development. These predictions allow for the forecasting of the second generation’s occurrence, with relatively small deviations (one to three days) observed at two different field sites. The insights from this study are critical for both understanding the ecology of M. loreyi and for informing practical management decisions, such as optimal placement of barriers to prevent immigration and strategies for controlling local populations.
‘Giving birth on a beach’: Women’s experiences of using virtual reality in labour
Authors: Massov Lorna , Robinson Brian , Rodriguez-Ramirez Edgar , Maude Robyn
Published: June 2024

Introduction

Birth is a normal physiological process, and many women want a natural birth. Women use a range of non-pharmacological pain relief methods to reduce labour pain intensity, to help manage labour pain and to induce relaxation. The purpose of this study was to explore the experiences of women using Virtual Reality as a non-pharmacological method of pain relief in labour. Virtual Reality has been shown to be an effective distraction technique in other acute pain settings which also reduces anxiety.

Methods

This study conducted qualitative in-depth interviews postnatally with women who used Virtual Reality in labour. Thematic analysis was used to analyse the qualitative data.

Results

Nineteen women used Virtual Reality in labour. Results from interviews with nineteen women in the postnatal period identified three main themes: impact of virtual reality on experience of labour, managing the pain of labour and challenges of using virtual reality in labour.

Conclusion

This study identified that Virtual Reality was effective as a relaxation technique and helped in pain management by the use of self-efficacy techniques. Women in this study also identified preferred virtual environments specifically to use during labour and birth. This study provides a unique and original contribution to the field of Virtual Reality in labour and birth. It also identifies Virtual Reality as an acceptable and positive experience in the management of anxiety and labour pain.
Informed consent to midwifery practices and interventions during the second stage of labor—An observational study within the Oneplus trial
Authors: Häggsgård Cecilia , Rubertsson Christine , Teleman Pia , Edqvist Malin
Published: June 2024

Objectives

To study informed consent to midwifery practices and interventions during the second stage of labor and to investigate the association between informed consent and experiences of these practices and interventions and women’s experiences of the second stage of labor.

Methods

This study uses an observational design with data from a follow-up questionnaire sent to women one month after giving birth spontaneously in the Oneplus trial, a study aimed at evaluating collegial midwifery assistance to reduce severe perineal trauma. The trial was conducted between 2018–2020 at five Swedish maternity wards and trial registered at clinicaltrials.gov, no NCT03770962. The follow-up questionnaire contained questions about experiences of the second stage of labor, practices and interventions used and whether the women had provided informed consent. Evaluated practices and interventions were the use of warm compresses held at the perineum, manual perineal protection, vaginal examinations, perineal massage, levator pressure, intermittent catheterization of the bladder, fundal pressure, and episiotomy. Associations between informed consent and women’s experiences were assessed by univariate and multivariable logistic regression.

Findings

Of the 3049 women participating in the trial, 2849 consented to receive the questionnaire. Informed consent was reported by less than one in five women and was associated with feelings of being safe, strong, and in control. Informed consent was further associated with more positive experiences of clinical practices and interventions, and with less discomfort and pain from interventions involving physical penetration of the genital area.

Conclusion

The findings indicate that informed consent during the second stage is associated with feelings of safety and of being in control. With less than one in five women reporting informed consent to all practices and interventions performed by midwives, the results emphasize the need for further action to enhance midwives’ knowledge and motivation in obtaining informed consent prior to performance of interventions.
Application of an ensemble CatBoost model over complex dataset for vehicle classification
Authors: M. Pemila , R. K. Pongiannan , R. Narayanamoorthi , M. AboRas Kareem , Youssef Amr
Published: June 2024

The classification of vehicles presents notable challenges within the domain of image processing. Traditional models suffer from inefficiency, prolonged training times for datasets, intricate feature extraction, and variable assignment complexities for classification. Conventional methods applied to categorize vehicles from extensive datasets often lead to errors, misclassifications, and unproductive outcomes. Consequently, leveraging machine learning techniques emerges as a promising solution to tackle these challenges. This study adopts a machine learning approach to alleviate image misclassifications and manage large quantities of vehicle images effectively. Specifically, a contrast enhancement technique is employed in the pre-processing stage to highlight pixel values in vehicle images. In the feature segmentation stage, Mask-R-CNN is utilized to categorize pixels into predefined classes. VGG16 is then employed to extract features from vehicle images, while an autoencoder aids in selecting features by learning non-linear input features and compressing representation features. Finally, the CatBoost (CB) algorithm is implemented for vehicle classification (VC) in diverse critical environments, such as inclement weather, twilight, and instances of vehicle blockage. Extensive experiments are conducted using different large-scale datasets with various machine learning platforms. The findings indicate that CB (presumably a specific method or algorithm) attains the highest level of performance on the large-scale dataset named UFPR-ALPR, with an accuracy rate of 98.89%.
The effect of successful educational actions in transition from primary to secondary school
Authors: Roca Esther , Fernández Pilar , Troya Maria B. , Flecha Ainhoa
Published: June 2024

While data show improvement in terms of educational access, dropout rates are significant in many countries. In Spain, 28% of students drop out of school without finishing secondary school, more than double the EU average. Thus, extensive research has shown the consequences of the dropout phenomenon, including negative effects on employment, welfare dependency, as well as health and emotional problems. The transition from primary to secondary education is a critical turning point. This situation worsens in the case of refugee and migrant minors who are refugees or with migrant backgrounds. Although there is strong evidence revealing the potential of SEAs to advance educational success for all in different contexts, no research has yet explored the effect of SEAs on enabling a successful transition from primary to secondary education, which could considerably impact decreasing dropout rates. Drawing on a qualitative case study of a secondary educational centre in Spain, this study analyses the impact of the implementation of three SEAs in key aspects related to primary-secondary transitions. Findings show how the systematic implementation of SEAs impacts the ease of the primary-secondary transition: positive relationships between the educational community are promoted, school connectedness across transition is strengthened, and academic support networks are enhanced. The study therefore suggests the benefits of SEAs as strategies that can enhance positive primary-secondary school transitions in terms of students’ perception of belongingness, and academic performance.
Sexual health beliefs and prevention of sexually transmitted infections among cisgender women sex workers in Colombia
Authors: Perdomo Sandoval Luis Albeiro , Goberna-Tricas Josefina
Published: June 2024

Introduction

The stigma and social discrimination against cisgender women sex workers lead many of them to live in conditions characterized by social inequality, marginalization, persecution, and limited opportunities for sexual health literacy. Consequently, they are often compelled to establish a framework of preventive beliefs with little scientific validity, which they use to identify, mitigate, or avoid sexual health risks arising from their interactions with clients. This study investigates the sexual health beliefs that influence self-care practices aimed at preventing sexually transmitted infections among cisgender women sex workers in Colombia.

Methods

We conducted a qualitative study framed in Hermeneutic Phenomenology. In-depth interviews and discussion groups were conducted with 34 cisgender women sex workers over 18 years of age in the center of the cities of Bogotá and Barranquilla in Colombia.

Results

Seven themes emerged from the reflective and inductive thematic analysis of the narratives: (1) popular habits for the prevention of contagion, (2) ocular assessment of genitals, (3) condom lubrication, (4) suspicion of a hidden infection in the client, (5) saliva and oral contact as a source of contagion, (6) avoidance of semen contact, (7) and trust in God as protection.

Conclusions

The findings reflect the need for health and social professionals to promote participatory and inclusive cooperation with sex workers to update the framework of preventive beliefs that help them guide sexual health self-care with autonomy and self-efficacy, strengthening favorable beliefs and negotiating unfavorable ones. It is also essential to have a sex worker-informed sexual health policy that guides the promotion of sexual health that is sensitive to the needs and consistent with the risks of sex work and ensures friendly and non-oppressive preventive care environments for sex workers.
There’s more Spain beyond the sea? Contemporary documentaries on Equatorial Guinea
Authors: Cubero Alejandra Val
Published: June 2024

In the last decade of the twenty-first century, the colonial issue between Spain and Equatorial Guinea has been approached with greater interest than in previous periods, and numerous theses, research works and books have attempted to broach an issue that is little known in Spanish society. We start from the hypothesis that colonial relations between Spain and Africa are gaining greater interest in the Spanish academic world, and especially in the artistic field; where a notable number of film directors have dealt with the subject of Equatorial Guinea in their documentaries, in an attempt to seek keys to understanding aspects related to colonialism, racism, memory and Afro-descendance. This article presents five contemporary documentary films. These documentaries are: Un día vi diez mil elefantes (One Day I Saw 10,000 Elephants) (Guimerà and Pajares 2015: 00:77:00); El escritor de un país sin librerías (The Writer from a Country without Bookstores) (Serena 2019: 00:79:00), Manolito Nguema (Grunfeld 2019: 00:85:00); Anunciaron Tormenta (A Storm Was Coming) (Vázquez 2020: 00:88:00) and A todos nos gusta el plátano (We all Like Plantain) (Bermúdez 2021: 00:60:00).
Materializing Magic: How the Witches of Instagram Make the Invisible Visible Through Digital Photography and Editing Techniques
Authors: Best Sarah
Published: June 2024

Recently, contemporary witchcraft has become increasingly subject to commodification, with many practitioners criticized for their pursuit of the “witch aesthetic” on social media. With Instagram feeds featuring carefully staged photographs of tools, materials, and spaces related to the craft, these “Insta-witches” or “#witchesofinstagram” often use photo editing applications like Photoshop to digitally manipulate these images in order to enhance their magical or otherworldly dimensions. In this article, I argue that the excessive use of magical “stuff,” along with the staging and editing of images shared on social media does not have to be superficial or devoid of meaning. Rather, I explore how these Witches of Instagram participate in what anthropologist Jennifer Deger refers to as “thick photography”—a process of image creation and alteration that gives rise to multilayered stories capable of extending beyond the bounds of the ordinary. In this context, photography foregrounds the intuitive, imaginative, and embodied ways of knowing central to the practice of magic, making visible that which may otherwise remain invisible. These digital images thus become relationally constituted material surfaces where networks of bodies, objects and energies are visualized, revealing the porous boundaries between categories such as human and nonhuman, internal and external, material and immaterial, and mundane and magical.
Notes on Vibratory Models of Care
Authors: Ferrari Elisa , Kline Katherine
Published: June 2024

This text documents a workshop presented at the Witch Institute at Queens University, August 2021. In this workshop, we experimented with the medium of the dream. We draw from the onto-ethico-epistemology of Karen Barad to refigure the boundaries of the psychoanalytic method of containment. We consider practices of care and their cosmologies outside of the enclosure of psychic life as circumscribed by psychoanalysis. Rather than interpreting the dream as personal poeisis, we play with/in the practice of collective dreaming, re-casting the dream as a spell—that is, an agential and animating vibratory force.

Representaciones de género en el videoclip actual. La imagen de las mujeres en el reguetón femenino
Authors: Mata-Núñez Almudena
Published: June 2024

Esta investigación analiza la imagen de las mujeres en los videoclips de las reguetoneras más populares, en un género conocido por perpetuar representaciones de las mujeres como objetos sexuales. El principal objetivo es averiguar si las cantantes femeninas reproducen estos estereotipos o si generan discursos alternativos. Mediante una triangulación del análisis narrativo se ha determinado que las reguetoneras mantienen la iconografía dominante, aunque casi la mitad de las canciones ofrecen una concepción de la sexualidad femenina como forma de liberación. Las artistas se igualan visualmente a los hombres, adoptan símbolos de poder y se muestran como sujetos activos del discurso.
Una estrategia de creación de contenido basada en Bangtan, el universo narrativo transmedia de la banda de k-pop BTS
Authors: Díaz-Ardiaca Lara , Vidal-Mestre Montserrat , Freire-Sánchez Alfonso
Published: June 2024

El presente manuscrito investiga las particularidades de la creación de un universo narrativo transmedia en la industria musical surcoreana y su relación con el consumo de contenido realizado por los seguidores del k-pop. De manera específica, el estudio se centra en BTS, la banda más popular y premiada de este género así como en HYBE, la productora que se responsabiliza de su comunicación y relación con los medios. Por este modo, los objetivos principales son determinar cuáles son las características primordiales del branded content transmedia del sector musical surcoreano y examinar las acciones que integran este tipo de estrategia basada en el contenido de marca y sus tendencias de consumo por parte de ARMY, su fandom. A estos efectos, se plantea un análisis cualitativo de las 22 principales estrategias de comunicación que realiza la banda y su consecuente codificación según el tipo de relato, contenido, mensaje y objetivos e interacción que realizan los fans con el grupo de música. Los resultados permiten concluir que BTS ha encontrado la manera de introducir una estrategia de contenido de marca de éxito en un país comunicativamente conservador mediante una peculiar conexión entre la banda y los fans, los cuales realizan acciones voluntariamente para difundir la marca, amplificando el contenido ya creado previamente por la banda, y produciendo otros novedosos que expanden el universo narrativo transmedia impulsado por la productora de entretenimiento HYBE.
La representación juvenil en los medios de comunicación: Un análisis de prensa del caso navarro.
Authors: Tirapu Intxaurrondo Xabier
Published: June 2024

Partiendo de la idea de que el contexto mediático sobreexpone ciertas facetas de la plural vida joven, este articulo pretende describir la representación mediática juvenil vigente, para así comprender cómo se mira a la juventud, es decir, que (no) se expone y cómo se relata cuando se habla sobre jóvenes en los medios de comunicación. Para ello, se han analizado todas las publicaciones relativas a la juventud navarra en un periódico autonómico en el lapso de un año. Dicho análisis de prensa da cuenta de una representación mediática sesgada y estereotípica que termina por influir en la percepción pública que se tiene sobre la juventud.
La figura del periodista frente al fenómeno de la desinformación en la era digital
Authors: Martín Miguel , Fior Asja , Costa Escuredo Álex , Ruiz San Román José A.
Published: June 2024

El fenómeno de la desinformación se caracteriza por ser un modo de contar los hechos de una forma distorsionada que modifica la percepción de lo “real”. En ese sentido, merece la atención de ser analizado por la semiótica, ya que su mirada posibilita acercarnos al problema de la verdad desde un punto de vista estratégico. Para esta disciplina, el concepto “verdad” no se entiende como una correspondencia entre lo que se dice y los hechos, sino como un efecto de sentido que se crea en el discurso. Al respecto, se propone que un modo de enfrentarse a las fake news es revalorizar la figura del periodista, en tanto en cuanto su labor es la de elaborar información que, además de veraz, sea creíble. Asimismo, se enfatiza la necesidad de formar al periodista  para que sea capaz de dominar distintas estrategias de enunciación y persuasión presentes en cualquier configuración discursiva.

INSEGURANÇA JURÍDICA E A TITULAÇÃO DE TERRAS NOS ASSENTAMENTOS DO XINGU-ARAGUAIA (MT)
Authors: Lourenço Taiana Ciscotto Martins
Published: June 2024

A titulação de terras em assentamentos é considerada fundamental para a segurança alimentar, para o desenvolvimento socioeconômico dos assentados e tem o potencial de dinamizar o mercado de terras como consequência da regularização fundiária. Este artigo apresenta uma abordagem quanti-qualitativa que analisa a relação entre a titulação e a consolidação do território da agricultura familiar na fronteira agrícola do Xingu-Araguaia (MT). O objetivo principal é compreender os desdobramentos socioterritoriais do processo de regularização fundiária nos assentamentos do Xingu-Araguaia. Também busca-se identificar as características dos assentamentos e famílias assentadas da região bem como investigar o significado da titulação de terras entre os assentados. Verifica-se que a partir de 2020 houve uma aceleração da emissão de títulos de terras nos assentamentos dessa região, como resultado de políticas neoliberais implementadas no Brasil nos últimos anos. Além disso, evidencia-se que ao mesmo tempo que o título significa uma segurança para as famílias, ele também pode se tornar um instrumento de desestruturação dos assentamentos ao favorecer a expansão da fronteira agrícola, ameaçando estes territórios e os avanços conquistados nos últimos anos de luta pela terra.
A CONSTRUÇÃO SOCIAL DE PROBLEMAS AMBIENTAIS E A PRODUÇÃO DE INJUSTIÇA ESPACIAL: O BAIRRO RUA DIREITA, EM TRÊS RIOS – RJ
Authors: Batista Júnior Maurício Correia , Milanez Bruno
Published: June 2024

O presente artigo utiliza a construção social de problemas ambientais como proposta para discutir os problemas ambientais que são socialmente construídos no município de Três Rios – RJ. Com isso, o objetivo do estudo foi identificar as principais reivindicações ambientais dos moradores do bairro Rua Direita, em Três Rios, que é um bairro periférico que contém em seu território diversas fontes potenciais de poluição ambiental, incluindo diversas indústrias, o antigo lixão municipal e o novo aterro sanitário. Buscou-se verificar como a população interpreta a espacialidade desses problemas ambientais e avaliar a produção de injustiça espacial no local. Para isso, foram feitas entrevistas semiestruturadas com os moradores do bairro. Doze entrevistas foram realizadas e o principal problema ambiental identificado foi o aterro sanitário. A partir da operação do aterro, foi identificada a geração de chorume e o seu lançamento nos corpos hídricos do bairro. A população está exposta aos impactos ambientais do chorume. A decisão locacional de concentrar diversas atividades poluidoras no mesmo bairro revela a produção de uma zona de sacrifício dentro do município de Três Rios. O aterro sanitário, então, aparece como um promotor de injustiça espacial e ambiental com anuência do poder público.

As matas ciliares são regiões ambientais que contribuem para a purificação da água, e reduzem a vulnerabilidade às inundações. Este estudo objetivou analisar as variações sazonais da cobertura vegetal da Caatinga nas proximidades do Reservatório de Serrinha II - PE, Brasil. O conjunto de dados orbitais foi composto por imagens do satélite MSI - Sentinel 2, de 2016 a 2021, entre os períodos: chuvoso e seco. Assim, avaliaram-se as respostas espectrais dos índices: Normalized Difference Vegetation Index (NDVI) e Soil Adjusted Vegetation Index (SAVI), correlacionados com o Standardized Precipitation Index (SPI) e a variação volumétrica do reservatório. Os resultados evidenciaram que os índices indicaram crescimento da vegetação no período chuvoso e redução no período seco. De 2016 a 2018 foi identificado, ao correlacionar o SPI com os índices, a redução da vegetação devido a eventos de seca. De 2019 a 2021 tem-se um estágio de regeneração com um aumento positivo dos valores de SPI. Esses eventos também proporcionaram a redução de volume acumulado do reservatório, que apresentou o menor valor em 2017 (11,66 hm³). Com isso, a associação do SPI aos índices possibilitou a identificação de mudanças na cobertura vegetal e no volume do reservatório, ocasionadas por déficit pluviométrico.
Jalapão Mosaic: Perspectives and Challenges for Implementing the Sustainable Development Goals (SDGs)
Authors: Iwamoto Helga Midori , Leal Viviane Araújo de , Cançado Airton Cardoso
Published: June 2024

The objective of this article was to evaluate the stage of implementation of the SDGs in the municipalities that belong to the Jalapão Mosaic (JM), exploring the opportunities and obstacles to achieving the SDGs in this territory. The methodological basis involves a quantitative approach of hierarchical clusters and a correlation matrix based on secondary data, identifying the most relevant SDGs for the region and the challenges for their implementation. The study reveals 15 SDGs with high relevance for the JM, with emphasis on SDGs 1 (End Poverty), 2 (Zero Hunger), 3 (Quality Health), 4 (Quality Education), 8 (Decent Work and Growth Economic), 10 (Reducing Inequalities), 13 (Climate Action), 15 (Life on Earth) and 16 (Peace, Justice and Strong Institutions). However, several challenges prevent the full implementation of these objectives, such as the scarcity of financial and human resources, marked social inequalities, environmental degradation, weaknesses in governance and low social participation. The results showed that municipalities in the region are far from meeting the goals of the 2030 Agenda, despite having high performance in SDGs of the Economic Axis. Despite the obstacles, the study also presents positive perspectives for the future of the TCJ. The region has rich potential for sustainable development, driven by its rich biodiversity and natural resources. Furthermore, the growing interest in ecological tourism in the region can generate opportunities for local development. To overcome the challenges and achieve the SDGs in the JM, the study presents some recommendations, such as increasing investments in social and environmental public policies, strengthening local governance and social participation, promoting environmental education and valuing local culture, supporting the development of sustainable economic activities. As final considerations, it is proposed that local managers and stakeholders be trained to understand these goals, in order to guide public policies, so that municipalities observe the best practices inside and outside Tocantins for Socioeconomic Development. Furthermore, the study's conclusions and recommendations can be useful for formulating more effective public policies and promoting the well-being of local populations, contributing to the construction of a more prosperous and sustainable future for the region.

An immuno-DOT diagnostic assay for autoimmune nodopathy
Authors: Jentzer Alexandre , Taieb Guillaume , El Bechir Jérémie , Vincent Thierry , Devaux Jérôme Joël
Published: June 2024

Objectives

Autoimmune nodopathy (AN) is a life-threatening peripheral neuropathy mediated by four autoantibodies targeting axoglial cell adhesion molecules at the nodes of Ranvier: Neurofascin-155 (Nfasc155), PanNeurofascin (PanNfasc), Contactin-1 (CNTN1), and Contactin-associated protein 1 (CASPR1). Antibody detection is a strong biomarker for AN diagnosis and treatment monitoring. The aim of this study was to develop an immuno-dot assay (immuno-DOT) compatible with routine implementation in medical laboratories.

Methods

This new approach was compared to standard techniques: indirect immunofluorescence assay, cell-based assay, and ELISA. Sensitivities (Se) and specificities (Sp) were calculated on a cohort composed of 58 patients diagnosed with AN, 50 seronegative patients with chronic inflammatory demyelinating polyradiculoneuropathy, 20 healthy controls, 30 patients with Guillain-Barré syndrome, 20 with monoclonal gammopathy and 20 with Charcot-Marie-Tooth disease. The patients were diagnosed with AN based on compatible electro-clinical arguments and at least two positive standard techniques.

Results

Immuno-DOT sensitivities and specificities were Se=91 %, Sp=97 % for anti-Nfasc155; Se=80 %, Sp=94 % for anti-PanNfasc; Se=93 %, Sp=98 % for anti-CNTN1; and Se=87 %, Sp=94 % for anti-CASPR1. Immuno-DOT allowed the diagnosis within 3 h and the accurate follow-up of the immune reactivity and isotype, and dot intensity correlated with antibody titers following treatments. A longitudinal study indicated that immuno-DOT yielded reliable results even after six months of storage at −20 °C.

Conclusions

The diagnostic performance of immuno-DOT was satisfactory and compatible with routine implementation in medical laboratories.
Was ist ein philosophisches Problem?
Authors: Harbecke Jens
Published: June 2024

This paper approximates a definitional distinction between philosophical problems and scientific problems. It defends the claim that philosophical problems can be defined as certain inconsistent sets 𝕄 of propositions. This set is characterised by its minimality, the plausibility of its individual propositions, the non-empirical character of some of these propositions, and by the fact that a discursive context exists within which some of 𝕄’s non-mathematical non-empirical assumptions are rejected by argument. In particular, this extrinsic and pragmatic criterion constitutes the novel character of the definition presented. Starting from the concept of philosophical problem, a classification of philosophy as an academic and intellectual discipline is presented. The last part of the paper deals with the question whether such an analytical understanding of philosophy is to be understood exclusively, or whether other kinds of philosophy should still be considered possible.
Softcommunication – Zum Stellenwert informeller Mitarbeiterkommunikation bei betrieblichen Sprachqualifizierungen
Authors: Binner Eric
Published: June 2024

Betriebliche Sprachqualifizierungen in multinational agierenden Unternehmen spielen vor dem Hintergrund zunehmender sprachlicher Heterogenität eine entscheidende Rolle für die berufliche Handlungsfähigkeit von Beschäftigten. Die vorliegende Studie exploriert den Stellenwert informeller Mitarbeiterkommunikation am mehrsprachigen Arbeitsplatz und deren Rolle in betrieblichen Sprachkursen. Den empirischen Untersuchungsgegenstand bilden Interviewdaten aus Gesprächen mit Firmenangehörigen eines führenden deutschen Technologieunternehmens. Die inhaltsanalytische Auswertung lässt darauf schließen, dass die für informelle Gespräche erforderlichen soziopragmatischen Kompetenzen in betrieblichen Sprachqualifizierungen marginalisiert werden.
The Hegelian Master–Slave Dialectic inHistory and Class Consciousness
Authors: Potamias Spyros
Published: June 2024

The central axis of the article is the argument thatHistory and Class Consciousnessadopts from the Hegelian dialectics not only the category of totality but also the master–slave dialectic, although it never refers explicitly to the latter. Hence, in this article, we aim to detect the subtle influence that the Hegelian master–slave dialectic exerts onHistory and Class Consciousnessand, more specifically, on the constitution of the Lukacsian concepts of reification, praxis, working class-bourgeoisie interaction, working-class self-consciousness, autonomous subject. Our approach to the Hegelian master–slave dialectic is mostly – but not only – based on its philosophical–anthropological interpretation by A. Kojeve. Kojeve’s interpretation, by attributing a crucial role to labour in the mastery–slavery dialectic, focuses on that aspect of the Hegelian dialectic which, in our estimation, was determining forHCC.In addition, our approach to the Hegelian master–slave dialectic is based on some occasional references Lukacs has to it inYoung Hegelas well as on his interpretation latent inHistory and Class Consciousness.

The acquisition of a motor skill involves adaptations of spinal and supraspinal pathways to alpha motoneurons. In this study, we estimated the shared synaptic contributions of these pathways to understand the neural mechanisms underlying the short-term acquisition of a new force-matching task. High-density surface electromyography (HDsEMG) was acquired from the first dorsal interosseous (FDI; 7 males and 6 females) and tibialis anterior (TA; 7 males and 4 females) during 15 trials of an isometric force-matching task. For two selected trials (pre- and post-skill acquisition), we decomposed the HDsEMG into motor unit spike trains, tracked motor units between trials, and calculated the mean discharge rate and the coefficient of variation of interspike interval (COVISI). We also quantified the post/pre ratio of motor units’ coherence within delta, alpha, and beta bands. Force-matching improvements were accompanied by increased mean discharge rate and decreased COVISIfor both muscles. Moreover, the area under the curve within alpha band decreased by ∼22% (TA) and ∼13% (FDI), with no delta or beta bands changes. These reductions correlated significantly with increased coupling between force/neural drive and target oscillations. These results suggest that short-term force-matching skill acquisition is mediated by attenuation of physiological tremor oscillations in the shared synaptic inputs. Supported by simulations, a plausible mechanism for alpha band reductions may involve spinal interneuron phase-cancelling descending oscillations. Therefore, during skill learning, the central nervous system acts as a matched filter, adjusting synaptic weights of shared inputs to suppress neural components unrelated to the specific task.
The Lack of Synapsin Alters Presynaptic Plasticity at Hippocampal Mossy Fibers in Male Mice

Synapsins are highly abundant presynaptic proteins that play a crucial role in neurotransmission and plasticity via the clustering of synaptic vesicles. The synapsin III isoform is usually downregulated after development, but in hippocampal mossy fiber boutons, it persists in adulthood. Mossy fiber boutons express presynaptic forms of short- and long-term plasticity, which are thought to underlie different forms of learning. Previous research on synapsins at this synapse focused on synapsin isoforms I and II. Thus, a complete picture regarding the role of synapsins in mossy fiber plasticity is still missing. Here, we investigated presynaptic plasticity at hippocampal mossy fiber boutons by combining electrophysiological field recordings and transmission electron microscopy in a mouse model lacking all synapsin isoforms. We found decreased short-term plasticity, i.e., decreased facilitation and post-tetanic potentiation, but increased long-term potentiation in male synapsin triple knock-out (KO) mice. At the ultrastructural level, we observed more dispersed vesicles and a higher density of active zones in mossy fiber boutons from KO animals. Our results indicate that all synapsin isoforms are required for fine regulation of short- and long-term presynaptic plasticity at the mossy fiber synapse.

Published: June 2024

Representing the probability and uncertainty of outcomes facilitates adaptive behavior by allowing organisms to prepare in advance and devote attention to relevant events. Probability and uncertainty are often studied only for valenced (appetitive or aversive) outcomes, raising the question of whether the identified neural machinery also processes the probability and uncertainty of motivationally neutral outcomes. Here, we aimed to dissociate valenced from valence-independent (i.e., generic) probability (p; maximum atp = 1) and uncertainty (maximum atp = 0.5) signals using human neuroimaging. In a Pavlovian task (n = 41; 19 females), different cues predicted appetitive, aversive, or neutral liquids with different probabilities (p = 0,p = 0.5,p = 1). Cue-elicited motor responses accelerated, and pupil sizes increased primarily for cues that predicted valenced liquids with higher probability. For neutral liquids, uncertainty rather than probability tended to accelerate cue-induced responding and decrease pupil size. At the neural level, generic uncertainty signals were limited to the occipital cortex, while generic probability also activated the anterior ventromedial prefrontal cortex. These generic probability and uncertainty signals contrasted with cue-induced responses that only encoded the probability and uncertainty of valenced liquids in medial prefrontal, insular, and occipital cortices. Our findings show a behavioral and neural dissociation of generic and valenced signals. Thus, some parts of the brain keep track of motivational charge while others do not, highlighting the need and usefulness of characterizing the exact nature of learned representations.
