Sexual assault and the matrix of harm: Sexual assault survivors narrate their whole lives in more negative ways
Authors: Caputo MacKenzie , Fineman Max , Khan Shamus
Published: June 2024

This paper uses data from the American Voices Project, an interview study based on a random population sample, to explore the relationship between assault experiences and how people narrate their lives. Using quantitative sentiment analysis, we find that survivors of assault express significantly greater negative sentiment when asked to tell their life stories. These negative sentiments are observable throughout the entire interview, including before questions of assault are asked. Survivors of assault narrate their experiences with more anger, disgust, fear, and sadness, and less anticipation, joy, and trust than those who do not report assault experiences. We provide evidence that the negative sentiment associated with sexual violence is greater than having lost a parent and less than having experienced a significant financial hardship within the last month. We contextualize these findings with a qualitative evaluation of the interview transcripts, further substantiating our finding. Overall, this paper suggests that sexual violence is part of what we have called, drawing inspiration from the work of Beth Richie, a “matrix of harm” that structures people’s lives. While our finding is consistent with what we might expect given the negative life experiences and sequalae associated with sexual assault, it has important implications. Sentimental differences in narrating life experience are an important yet relatively understudied phenomenon, and experiences of assault are rarely asked about yet may be consequential to both quantitative and qualitative accounts of social processes.

Leprosy is a chronic infectious disease caused by the bacillus Mycobacterium leprae. The disease may evolve for inflammatory reactions, reversal reaction (RR) and erythema nodosum leprosum (ENL), the major cause of irreversible neuropathy in leprosy, which occur in 1 in 3 people with leprosy, even with effective treatment of M. leprae. Leprosy remains persistently endemic in our region where it predominantly affects lowest socioeconomic conditions people, as Toxoplasma gondii infection in the municipality studied. Previously, we have shown T. gondii coinfection as a risk marker for leprosy, mainly in its severe form. This present study assessed whether T. gondii infection is also a risk factor for leprosy reactions and the predictive value of immunoglobulin production prior to development of leprosy reactions. Patients with leprosy (n = 180), co-infected or not with T. gondii, had their serum investigated for levels of IgA, IgE, IgG1, IgG2, IgG3 and IgG4 anti-PGL-1 by ELISA prior to development of leprosy reactions. The serologic prevalence for T. gondii infection was 87.7% in leprosy reaction patients reaching 90.9% in those with ENL. The leprosy reaction risk increased in T. gondii seropositive individuals was two-fold ([OR] = 2.366; 95% confidence interval [CI 95%]: 1.024–5.469) higher than those seronegative, and considering the risk of ENL, this increase was even more evident (OR = 6.753; 95% CI: 1.050–72.85) in coinfected individuals. When evaluated the prediction of anti-PGL-1 immunoglobulin levels for development of leprosy reactions in patients coinfected or not with T. gondii, only the increase IgE levels were associated to occurrence of reactional episodes of leprosy, specifically ENL type, in patients coinfected with T. gondii, compared to those not coinfected or no reaction. Thus, the immunomodulation in co-parasitism T. gondii–M. leprae suggest increased levels of IgE as a biomarker for early detection of these acute inflammatory episodes and thereby help prevent permanent neuropathy and disability in leprosy patients.

Published: June 2024

One of the largest isotopic datasets of the ancient Eastern Mediterranean region is evaluated, based on plants (n = 410), animals (n = 210) and humans (n = 16) from Tell Tweini (Syria). Diachronic analysis of plant and faunal specimens from four main periods of occupation: Early Bronze Age (2600–2000 BC), Middle Bronze Age (2000–1600 BC), Late Bronze Age (1600–1200 BC) and Iron Age (1200–333 BC) were investigated. Mean Δ13C results from seven plant species reveal emmer and free threshing wheat, olives, bitter vetch, rye grass and barley were adequately or well-watered during all periods of occupation. The grape Δ13C results suggest excellent growing conditions and particular care for its cultivation. The δ15N results indicate that especially the emmer and free threshing wheats received some manure inputs throughout the occupation sequence, while these were likely further increased during the Iron Age, encompassing also the olive groves and grape vineyards. Generally, domestic animals (cattle, sheep, goats) had C3 terrestrial diets and were kept together in similar environments. However, some animals consumed significant amounts of marine or C4 plants, possibly from disturbed habitats due to land use pressure or salt tolerant grasses and shrubs from wetland environments, which were recorded in the direct vicinity of the site. Middle Bronze Age humans consumed a C3 terrestrial diet with no measurable input from C4, freshwater or marine protein sources. Interestingly, the human diet was relatively low in animal protein and appears comparable to what is considered today a typical Mediterranean diet consisting of bread (wheat/barley), olives, grapes, pulses, dairy products and small amounts of meat. The combined isotopic analysis of plants, animals and humans from Tell Tweini represents unbroken links in the food chain which create unparalleled opportunities to enhance our current understanding of environmental conditions, climate change and lifeways in past populations from the Eastern Mediterranean.
When TV neighbours become good friends: Understanding Neighbours fans’ feelings of grief and loss at the end of the series
Authors: Gerace Adam
Published: June 2024

Fans may experience significant upset and distress when a television series ends. However, grief and loss reactions to the end of a fictional series have seldom been investigated. It is likely that the degree to which such reactions are felt is influenced by viewing motives (e.g., pleasure, meaning making), connection to the series and its fan community, relationships formed with characters, including parasocial bonds and experiences of empathy, and tendency to engage with others’ perspectives and emotions, including fictional characters. The purpose of this study was to examine predictors of fans’ grief and loss reactions to the end of the television series Neighbours, which aired from 1985 to 2022. Fans (n = 1289) completed an online survey shortly after the screening of the final episode. The survey measured grief emotions and cognitions, acceptance that the series had ended, distress at the loss of a parasocial relationship with a favourite character, feelings of closure, and expressions of gratitude for the series. Predictors of these grief and loss reactions examined in the survey were viewing motives, fan identity, strength of a parasocial relationship formed with a favourite character, empathy towards that character, and tendency to take others’ perspectives, experience empathic concern and personal distress, and tendency towards engagement with fictional characters. Greater grief and loss reactions were experienced by fans whose motives for watching involved being entertained and exposed to different lifestyles, who felt a stronger fan connection to the series, and who formed stronger parasocial empathic relationships with their favourite character. Factors such as gender, age, and empathic tendencies predicted various types of grief reactions. Understanding fan experiences when a long-running series ends advances theory and research on viewer parasocial relationships and engagement with media, as well as providing evidence that the loss of a series or favourite character can be viewed as a type of grief experience.
Service quality, satisfaction, and intention to use Pourasava Digital Center in Bangladesh: The moderating effect of citizen participation
Authors: Biswas Bikram , Nur Ullah Mohammad , Rahman Md Mostafizur , Al Masud Anas
Published: June 2024

This study describes how, as part of the administrative reform of Bangladesh, most of the urban local governments have set up some public service center like Pourasava Digital Center (PDC), where ICT (Information and Communication Technology) has been commonly applied to make e-services more convenient, efficient and transparent. The current study measures the Service Quality Satisfaction and Continuous Use Intention to use Pourasava Digital Center (PDC) in Bangladesh by adopting citizen participation as a moderator. Theoretically, this study has used the DeLone & McLean Information Systems (D&M IS) Success Model and Zhang’s two-dimensional satisfaction model. However, most of the existing studies in Bangladesh are qualitative, and the relationship between service quality and citizen satisfaction has not been tested. A survey was conducted based on a structured questionnaire method and data collected from 332 respondents from 05 PDC and applying structural equation modelling in AMOS software while analyzing the data. The empirical results showed that the data fit the model. The finding of this study is that information quality affects specific satisfaction but not accumulative satisfaction, and specific satisfaction might not lead to accumulative satisfaction. One of the worthy findings of this study is that citizen satisfaction is highly dependent on system quality and service quality rather than information quality. The continuous use intention of the citizen is not based on specific satisfaction but significantly depends on accumulative satisfaction. To ensure the improvement of PDC’s service quality, all dimensions related to the quality of service should be modified, and the administrative system and citizens should be encouraged to participate in all aspects of services.
Hearing loss and psychosocial outcomes: Influences of social emotional aspects and personality
Authors: Cormier Kayla , Brennan Christine , Sharma Anu
Published: June 2024

The aim of this study was to examine the effects of social isolation, loneliness, anxiety, depression, higher stress, and memory complaints interacting with personality traits as a function of hearing loss. Personality traits have previously been shown to correlate with anxiety and depression, as well as hearing loss, suggesting an effect of personality on the relationship between social emotional outcomes and hearing loss. A cross-sectional survey including validated screening measures was anonymously administered. Measures included personality (Big Five Index-2 Extra-Short Form), stress (Perceived Stress Scale), anxiety and depression (Patient Health Questionnaire for Depression and Anxiety), loneliness (Three-Item Loneliness Scale), social engagement (Lubben Social Network Scale-6), and self-perceived memory complaints (Subjective Cognitive Function). Eight hundred and ninety-one responses were obtained from adults between the ages of 18 and 90 years old (M = 50 years old). Hearing loss was positively correlated with subjective memory complaints only when not accounting for demographic variables, personality traits, psychosocial outcomes, and social emotional outcomes. There were additive effects of hearing loss and negative emotionality on increases in memory complaints in those who self-identified as maybe having hearing loss. Higher degrees of hearing loss also increased loneliness, with greater hearing loss negating the positive correlation between extraversion and social engagement. Overall, our results suggest that hearing loss significantly interacts with personality traits and other social emotional measures. Our results suggest that the impact of hearing loss on memory complaints, social isolation, and loneliness may differ across patients with hearing loss in comparison with those who think they maybe have hearing loss. Information from this study may provide insights for hearing healthcare and mental healthcare professionals to better serve persons with hearing loss who may require additional support or interventions.
Update of the cooling protocol for antibiotic-free storage of boar semen at 5°C improves sperm quality and maintains low bacterial counts
Authors: Luther Anne-Marie , Nguyen Thu Quynh , Verspohl Jutta , Waberski Dagmar
Published: June 2024

Preserving boar semen at 5°C instead of the conventional storage temperature of 17°C would enable a reduction of antibiotic use in pig insemination. To protect the chilling-sensitive boar spermatozoa, holding the extended semen at a higher temperature before cooling could be beneficial and facilitate the implementation of the innovative preservation concept in practice, provided that bacterial growth is kept at a low level. The aim of this study was to introduce a holding time (HT) at 17°C before cooling and to examine the effect on sperm quality and bacterial growth compared to the original cooling protocol for antibiotic-free 5°C semen storage. A series of experiments with semen doses from eight boars extended in Androstar® Premium without conventional antibiotics revealed that sperm kinematics and the integrity of sperm plasma membranes and acrosomes were improved with HT between 16 and 24 h followed by delayed cooling with 0.04°C/min when compared to the original protocol for semen preservation at 5°C (p < 0.05). Both a shorter HT of 6 h and a faster cooling rate of 0.07°C/min reduced sperm quality (p < 0.05). The HT for 24 h did not compromise the inhibitory effect on bacterial growth during long-term semen storage at 5°C, not even in semen doses spiked with Serratia marcescens. In conclusion, semen storage at 5°C with the modified cooling protocol improved sperm quality and is antimicrobially efficient. It thus presents a ready-to-use tool for a reduction or replacement of antibiotics in pig insemination.

Pessoa, persona & personagem: o imaginário fã em Real Person Slash
Authors: De Araújo Utzig Ingrid Lara
Published: June 2024

Fanfictions são práticas transformativas baseadas em produtos culturais como livros, filmes, animes, mangás, HQs e outros materiais-fonte. Este artigo problematiza o subgênero Real Person Slash (RPS), estabelecido não pela reescritura de uma história, mas pela ficcionalização da vida e dos (supostos) relacionamentos homoafetivos entre artistas, na qual os bandoms acessam as celebridades como artefatos midiáticos por meio de fragmentos de informação em níveis textuais e extratextuais (entrevistas, vídeos, performances, fotos, notícias em revistas de fofoca). Para este estudo, foi selecionada uma fanfic sobre membros da girlbandFifth Harmony. Durante a análise, percebeu-se que fics RPS manipulam a figura pública (persona), transformando-a em personagem para o qual se cria um eu privado (pessoa) ficcional, em busca de identificação e representatividade. Concluiu-se que RPS, enquanto repertório literário, é pautada em atos de fingir, conforme proposição de Wolfgang Iser (1999) em suas observações acerca do fictício e do imaginário.
Minha Terra Tem ____________: Patterns of Text Reuse in “Song of Exile” and its Intertexts
Authors: Alma Enslen Joshua , R. Bell Jocelyn
Published: June 2024

A foundational text of Brazilian Romanticism, Antônio Gonçalves Dias’s “Canção do Exílio,” written in Coimbra (1843) and published in Niterói (1846), is uniquely positioned as Brazil’s most imitated poem. Based on a data set of 500 intertexts spanning the years 1846-2015, this study contemplates the nature of textual borrowing found in the poem’s variations. Looking beyond words shared across texts to the syntactic patterns at play, this paper defines and discusses in detail the concept of Syntactic Templates, develops an algorithm for their identification and considers their utility for understanding this specific text reuse problem.
‘O SUJEITO E SEU LUGAR NO MUNDO’: PROBLEMATIZANDO A BASE NACIONAL COMUM CURRICULAR A PARTIR DAS PRÁTICAS SOCIOESPACIAIS DE JOVENS E DA EDUCAÇÃO EM PERIFERIAS URBANAS
Authors: Correia Silvia Letícia Costa Pereira , Lastória Andrea Coelho
Published: June 2024

O artigo evidencia as contribuições conceituais das práticas socioespaciais produzidas por jovens no espaço do bairro e o desenvolvimento de uma Educação em periferias urbanas, à análise da unidade temática ‘o sujeito e seu lugar no mundo’, proposta na Base Nacional Comum Curricular (BNCC) para o Ensino Fundamental. É norteado pela seguinte questão: de que maneira as práticas socioespaciais produzidas por jovens, no espaço do bairro e o desenvolvimento de uma Educação em periferias urbanas, podem contribuir conceitualmente à análise da unidade temática na BNCC no Ensino Fundamental? Para tanto foi realizado um estudo teórico da BNCC, especificamente o componente de Geografia, além de uma investigação empírica envolvendo a técnica de associação livre de palavras, a hierarquização de itens e os mapas afetivos. A partir da concepção dos sujeitos sobre o espaço vivido e as práticas sociais cotidianas experienciadas no bairro, observa-se a emersão de conhecimentos do senso comum tributários das Representações Sociais do espaço, que dentro da escola potencialmente reformulam os currículos praticados. A discussão proposta nos remete a um enfoque pedagógico considerando as ações cotidianas, o enredamento com o mundo da vida, a ação criativa e a produção de sentido, prenunciando desdobramentos para documentos norteadores da Educação.

Vestígios arqueológicos da Tradição São Francisco tem sido recorrentemente encontrados na parte meridional do estado de Minas Gerais e na Zona da Mata mineira, a exemplo do sítio arqueológico Toca do Índio (Chiador, MG), ponto focal do presente artigo, cujo objetivo é interpretar o aludido sítio arqueológico a partir de uma relação dialógica entre a abordagem geossistêmica e a arqueologia da paisagem. Os resultados apontaram relações com as paisagens regionais dadas pela posição da caverna em um sítio estratégico, funcionando como um mirante que desvela uma ampla visada regional numa época em que uma vicejante cobertura de florestas semidecíduas que se colocava como elemento de dificuldade para deslocamentos e observações. O sítio em apreço, por sua vez, ostenta inscrições rupestres que consorciam figuras abstratas e alguns elementos zoomorfos recorrentemente encontrados nas pinturas da Tradição São Francisco; horizonte cultural cuja filiação dos vestígios encontrados é mais provável. Constatou-se ainda que o sítio apresenta considerável rol de ameaças naturais e antrópicas, urgindo assim práticas conservacionistas capazes de proteger o local e seu entorno.

Published: June 2024

Transtornos Mentais e Comportamentais (TMC) são caracterizados por perturbações na cognição, regulação emocional e comportamento do indivíduo. Este estudo realizou o mapeamento multitemporal da taxa de TMC no Estado de São Paulo entre 2008 e 2021. A detecção e análise de agrupamento espacial foi realizada com técnicas de estatística espacial. Existe uma dependência espacial entre os municípios do estado de São Paulo quanto à taxa de TMC no período de 2008 a 2021. Uma oscilação nos casos de TMC nos municípios nos últimos anos foi evidenciada. Os homens são mais acometidos que as mulheres e a faixa etária de 20 a 59 anos de idade a de maior risco. Conclui-se que o padrão de distribuição da taxa de TMC não é aleatório no Estado de São Paulo, sendo as mesorregiões de Campinas, Assis e Marília as mais preocupantes no estado. Este trabalho encontrou padrões e tendências na distribuição da taxa de TMC relacionados ao uso de substâncias psicoativas em diferentes regiões do Estado de São Paulo. Isso pode ajudar a planejar e implementar políticas públicas mais efetivas de prevenção e tratamento para esses transtornos nas áreas de maior ocorrência.

Strategi Pengelolaan Sumber Daya Teripang Ekonomis Penting di Kepulauan Karimunjawa
Authors: Putri Amanda Nerissa , Hartoko Agus , Prakoso Kukuh
Published: June 2024

Teripang merupakan komoditas perikanan ekonomis penting yang banyak dikonsumsi oleh masyarakat baik lokal maupun internasional. Permintaan yang tinggi memicu pemanfaatan teripang secara berlebihan. Kegiatan eksploitasi teripang masih mengandalkan penangkapan di alam, apabila pemanfaatannya berlebihan akan memicu penurunan jumlah populasi. Hal tersebut kurang diimbangi dengan kegiatan pengelolaan yang baik, sehingga teripang dapat terancam punah. Kegiatan penelitian dilaksanakan pada Agustus-September 2023 di Kepulauan Karimunjawa. Tujuan peneltian ini untuk mengetahui jenis-jenis teripang ekonomis penting, mengetahui persepsi dan partisipasi nelayan, pengepul, pengelola (stakeholders) dalam pengelolaan sumber daya teripang, serta strategi pengelolaan sumber daya teripang ekonomis penting. Metode penelitian menggunakan penelitian kualitatif dengan pengumpulan data obervasi di lapangan, sampling di lapangan, dan wawancara menggunakan kuesioner. Penentuan responden dengan metode sensus, terdapat sebanyak 30 responden. Pembobotan data menggunakan skala Likert dan analisis data menggunakan analisis SWOT. Terdapat 26 teripang hasil tangkapan yang diperoleh, diantaranya teridentifikasi 9 spesies teripang ekonomis penting yaitu Holothuria flavomaculata, Stichopus ocellatus, Holothuria pervicax, Holothuria fuscocinerea, Isostichopus badionotus, Stichopus horrens, Holothuria spinifera, Bohadschia suburbra, dan Bohadschia argus. Nelayan, pengepul dan pengelola setempat menyadari bahwa pengelolaan sumber daya teripang sangat penting untuk dilaksanakan. Alternatif strategi pengelolaan yang didapat yaitu weakness-opportunity (turnaround), diantaranya yaitu memperkenalkan metode pada teknologi budidaya teripang, menegakkan kebijakan peraturan ukuran tangkap dan musim penangkapan dengan memberikan perhatian khusus untuk sumber daya teripang dan mengoptimalkan kegiatan pendataan secara rutin untuk memperoleh informasi terkait sumber daya teripang. Strategi WO berpotensi memulihkan kembali populasi sumber daya teripang ekonomis penting di Kepulauan Karimunjawa yang menurun.
Sildenafil amplifies calcium influx and insulin secretion in pancreatic β cells
Authors: Murao Naoya , Morikawa Risa , Seino Yusuke , Shimomura Kenju , Maejima Yuko , Yamada Yuichiro , Suzuki Atsushi
Published: June 2024

Sildenafil, a phosphodiesterase‐5 (PDE5) inhibitor, has been shown to improve insulin sensitivity in animal models and prediabetic patients. However, its other metabolic effects remain poorly investigated. This study examines the impact of sildenafil on insulin secretion in MIN6‐K8 mouse clonal β cells. Sildenafil amplified insulin secretion by enhancing Ca2+ influx. These effects required other depolarizing stimuli in MIN6‐K8 cells but not in KATP channel‐deficient β cells, which were already depolarized, indicating that sildenafil‐amplified insulin secretion is depolarization‐dependent and KATP channel‐independent. Interestingly, sildenafil‐amplified insulin secretion was inhibited by pharmacological inhibition of R‐type channels, but not of other types of voltage‐dependent Ca2+ channels (VDCCs). Furthermore, sildenafil‐amplified insulin secretion was barely affected when its effect on cyclic GMP was inhibited by PDE5 knockdown. Thus, sildenafil stimulates insulin secretion and Ca2+ influx through R‐type VDCCs independently of the PDE5/cGMP pathway, a mechanism that differs from the known pharmacology of sildenafil and conventional insulin secretory pathways. Our results reposition sildenafil as an insulinotropic agent that can be used as a potential antidiabetic medicine and a tool to elucidate the novel mechanism of insulin secretion.

Published: June 2024

A program for writing words (or personal names) by combining chemical element symbols is developed in the context of classroom activity to introduce the periodic table, properties of elements, and periodic trends. We provide multiple examples and possible ideas to improve student engagement and create an inclusive environment in the classroom. Common confusions and mistakes made when learning the periodic table are tabulated and discussed. In addition to spelling words and creating graphics using element symbols, the program can display and print out properties of elements as part of the word-building game.
Zur Ambivalenz von ‚Werten‘ in Diskussionen zur Klima- und Umweltethik
Authors: Düwell Marcus
Published: June 2024

In environmental ethics, many approaches are searching for a justification of the protection of nature and biodiversity via an account of the intrinsic or inherent value of non-human nature, i. e. a justification that does not rely on the perspective of human beings. This leads to intricate problems regarding value theory. This paper proposes to avoid those problems by investigating explicitly anthropocentric pathways. It discusses what kinds of reasons for the protection of nature can be developed from the consistent practical self-understanding of agents. First, it is argued that the practical commitments of agents necessarily involve some normative commitments to the protection of the generic conditions of agency, which are particularly relevant for the ecological conditions that enable us to act and to realise goals. Second, it is discussed whether the presence of non-human nature is particularly relevant from the perspective of philosophical anthropology. Is it not important for human beings to experience non-human nature as an environment that is not fully planned and designed by human beings? The general aim is to show that it is worthwhile to search for justifications of the protection of nature and biodiversity from the practical self-understanding of human beings.
Towards equitable multilingualism: promoting transdisciplinary, collaborative dialogue between English as a lingua franca and translingualism

Inspired by Hult’s (2010. Theme-based research in the transdisciplinary field of educational linguistics. In Francis M. Hult (ed.), Directions and prospects for educational linguistics, 19–32. Springer) discussion of theme-based research within educational linguistics that focuses, first and foremost, on solving problems rather than adhering to disciplinary boundaries and conventions, this article calls for transdisciplinary collaboration to resolve educational problems related to monolingualism, native-speakerism, and the hegemony of colonial ideologies. More specifically, we make a case for transdisciplinary dialogue between English as a lingua franca (ELF) and translingualism. We argue that these two research fields, with their increasingly converging interests and goals as well as distinct strengths, can make a greater impact in addressing persistent educational problems through targeted collaboration, research, and (language) pedagogy based on equitable multilingualism (e.g., Ortega, Lourdes. 2019. SLA and the study of equitable multilingualism. The Modern Language Journal 103. 23–38). In this conceptual paper, we first introduce translingualism and ELF as equally legitimate multilingual theories. Next, we identify shared key tenets and orientations as well as distinctive vantage points of each approach that researchers and educators can take advantage of for collaboratively addressing problems within classrooms and beyond. Finally, we lay out a vision for how this transdisciplinary, collaborative dialogue can help realize more equitable multilingualism.
Verfasserverweise und Typen wissenschaftssprachlichen Handelns: Eine vergleichende Korpusstudie anhand deutscher und polnischer Abschlussarbeiten
Authors: Matthies Jochen
Published: June 2024

Der Artikel beschäftigt sich mit verschiedenen Typen von Verfasserverweisen in wissenschaftlichen Texten und ihrer formalen Realisierung in verschiedenen wissenschaftskulturellen Kontexten. Es wird zwischen Textverweisen, Methodikverweisen und Eristikverweisen unterschieden. Auf dieser Grundlage wird eine Korpusstudie mit deutschsprachigen Abschlussarbeiten auf Bachelor-, Master- und Promotionsniveau vorgenommen. Die Texte stammen jeweils zur Hälfte aus Deutschland und Österreich und zur Hälfte aus Polen. Es zeigt sich, dass die drei unterschiedenen Verweistypen mit klar unterscheidbaren sprachlichen Mustern korrelieren. Diese Muster liegen in den L1-Arbeiten über die Niveaus hinweg relativ konstant vor. Der L2-Sprachgebrauch nähert sich diesen Mustern mit steigendem Qualifikationsniveau an. Ein Vergleich mit polnischsprachigen Doktorarbeiten deutet zudem darauf hin, dass sich Abweichungen in der sprachlichen Realisierung von Verfasserverweisen teilweise auf den Einfluss der polnischen Sprache beziehungsweise Wissenschaftskultur zurückführen lassen.
Isolation of stilbenoids from fresh knotwood of Scots pine using a high yield method
Authors: Saadabadi Atefeh , Korotkova Ekaterina , Eklund Patrik C.
Published: June 2024

Scots pine knotwood contains valuable amount of stilbenoids such as pinosylvin (Ps) and pinosylvin monomethyl ether (PsMME). The stilbenoids have numerous biological activities. Traditional methods of extracting stilbenoids often yield low quantities and involve complex processes. In the present study, a simple and high-yield method was proposed for the extraction of stilbenoids from fresh Scots pine knotwood using ethanol taking a total of three days. In addition, the impact of drying process, extraction time, extraction solvents (acetone and ethanol) and storage time were evaluated on the yield of the stilbenoids. The increased yield and improved extraction efficiency make this method a promising advancement for promoting the utilization of stilbenoids for their valuable bioactive properties.

We investigated sex differences in dopamine (DA) release in the nucleus accumbens (NAc) and dorsolateral striatum (DLS) using a chronic 16-channel carbon fiber electrode and fast-scan cyclic voltammetry (FSCV). Electrical stimulation-induced (ES; 60 Hz) DA release was recorded in the NAc of single- or pair-housed male and female rats. When core (NAcC) and shell (NAcS) were recorded simultaneously, there was greater ES DA release in NAcC of pair-housed females compared with single females and males. Housing did not affect ES NAc DA release in males. In contrast, there was significantly more ES DA release from the DLS of female rats than male rats. This was true prior to and after treatment with methamphetamine. Furthermore, in castrated (CAST) males and ovariectomized (OVX) females, there were no sex differences in ES DA release from the DLS, demonstrating the hormone dependence of this sex difference. However, in the DLS of both intact and gonadectomized rats, DA reuptake was slower in females than that in males. Finally, DA release following ES of the medial forebrain bundle at 60 Hz was studied over 4 weeks. ES DA release increased over time for both CAST males and OVX females, demonstrating sensitization. Using this novel 16-channel chronic FSCV electrode, we found sex differences in the effects of social housing in the NAcS, sex differences in DA release from intact rats in DLS, and sex differences in DA reuptake in DLS of intake and gonadectomized rats, and we report sensitization of ES-induced DA release in DLS in vivo.
Termites and Rough Theatre
Authors: Phillips M. Scott
Published: June 2024

Poet and art critic David Antin observed that, to a great degree, video art derives significance from its relation to some aspect of television. This article acknowledges this and examines video art in the context of a cultural critique via a distinctive mixture of cross-disciplinary collaborations within the arts during the latter half of the twentieth century.

While the video art Antin described can be considered an extension of the postwar recalibration of the emphasis placed on art as object, it was also the beneficiary of early twentieth-century experimentation, such as Dada’s challenge to notions of art and expectations regarding aesthetics, as well as early experimentation in cinema. This intersection of culture and art histories finds its way into the early video work of Daniel Boord.

My main interest in Boord’s work is its relation to experimentation with theatricality, an area not usually associated with video art. Boord’s “lowbrow” absence of pretense and disregard for reductive formalism align well with Peter Brook’s conception of the “Rough Theatre,” as well as film critic Manny Farber’s notion of “termite art,” art that “feels its way through walls of particularization” and eats at its own boundaries. Boord’s work is a self-propelled dizzying array of humor, ideas, and juxtapositions that are well suited for the twentieth century—work that moves along according to its own self-defined boundaries of invention.
Nuevas técnicas para viejos argumentos. Diagramación y evaluación de argumentos en Aristóteles, a propósito de la amistad.
Authors: Ramírez Daza y García Rómulo
Published: June 2024

La complejidad de los argumentos filosóficos en general, y de los aristotélicos en particular, hacen viable nuevos intentos de interpretación que pueden arrojar cierta luz a las metodologías clásicas. La presente investigación permitirá focalizar futuros intentos hacia una mayor comprensión del pensamiento del Estagirita, a partir de las razones que aducen algunas técnicas de identificación y diagramación de argumentos. Con ello se pretende acercar más al lector a esta sabiduría de la Antigüedad. Estos recursos metodológicos permiten a su vez visualizar más a detalle las pruebas argumentales, y estudiar más de cerca las conexiones proposicionales al interior de la estructura de los razonamientos. En esta investigación se ensayan cuatro pasajes de la Ética a Nicómaco de Aristóteles con el fin de mostrar suficientemente la identificación, análisis y diagramación de tales argumentos, a propósito del tema de la amistad, alumbrando con ello la naturaleza dialéctica y retórica de la filosofía práctica.
The normativity of logic and the natural normativity of argumentation
Authors: Massolo Alba
Published: June 2024

In this paper, I defend that logic has a normative status for reasoning. To support my argument, I question whether logic can be limited to a formal calculus that establishes relations among truth-bearers (Goldstein, 1988). Instead, I argue that logic encompasses the study of inference in ordinary language. Similarly, I challenge traditional views of reasoning that depict it as a private process of drawing inferences. Instead, I embrace perspectives that view reasoning as a social activity (Dutilh-Novaes, 2021; Godden, 2015; Kalis, 2022; Mackenzie, 1989). From these bases, I explore the concept of the natural normativity of argumentation (Gilbert, 2007; Jackson, 2019). Since argumentative practices inherently possess a normative dimension, logic aims to capture and represent the rules that govern these linguistic exchanges. Logical rules are the tools from which agents can exert normative control over argumentative practices.
¿Puede la ciencia hablar en español? Consideraciones glotopolíticas sobre la controversia en torno a las lenguas de la comunicación científica en el VIII Congreso Internacional de la Lengua (2019)
Authors: Von Stecher Pablo , Nahabedian Juan Javier
Published: June 2024

El uso dominante del inglés en la comunicación científica especializada ha potenciado, sobre todo en las últimas décadas, el proceso de minorización lingüística del español (entre otras lenguas) en este ámbito. Inscripto en un enfoque glotopolítico, perspectiva que estudia las diferentes intervenciones que la sociedad ejerce sobre el lenguaje, este artículo analiza la dimensión argumentativa de los posicionamientos en torno al uso de lenguas para la difusión científica, que tuvieron lugar en el VIII Congreso Internacional de la Lengua Española (2019). Mientras que los discursos dominantes de la controversia naturalizan, a través de preguntas retóricas y metáforas prototípicas (bélicas, lúdicas), la convicción de que el inglés es la lengua franca de la ciencia; otras voces apelan a argumentos cuantitativos, en términos de número de hablantes y extensión espacial del español, con el fin de reivindicarlo, así como refieren el compromiso del investigador con el país que permitió su formación.
El discurso de odio como medio para la exclusión argumentativa
Authors: Domínguez Armas Álvaro , Anttila Solmu
Published: June 2024

La exclusión argumentativa ocurre cuando se le niega la participación a un agente en un intercambio argumentativo. En la primera parte del artículo planteamos una taxonomía de exclusiones argumentativas basada en tres ejes: estructural, causal y consecuencial. En la segunda parte del artículo analizamos el discurso de odio como un medio para la exclusión argumentativa. El discurso de odio refiere a las expresiones públicas que discriminan y subordinan a sus víctimas por su pertenencia a (o representación de) un grupo vulnerable. Argumentamos que las formas de discurso de odio explícitas contribuyen a la exclusión activa y completa de las víctimas. Después observamos que el discurso de odio implícito puede excluir a sus víctimas por medio de su inclusión en debates donde no quieren participar. Para ello, estudiamos un intercambio comunicativo en Twitter donde se utiliza el discurso de odio. Lo que nos llevará a plantear el concepto de “inclusión argumentativa forzada” como forma de exclusión argumentativa
