Navigating the Future: Nanotechnological Strategies for Tackling Hepatocellular Carcinoma
Authors:   The Assam Royal Global University, Department of Zoology, Guwahati, Assam 781035, India, Kumari Annu
Published: November 2023

Hepatocellular carcinoma (HCC), a widely prevalent form of liver malignancy, is a leading contributor to cancer-related mortality globally, despite advances in preventive and diagnostic technologies. It is closely associated with cirrhosis, with major contributions from hepatitis B and C infections and alcohol consumption. Early detection of HCC is crucial as it is often diagnosed at an asymptomatic stage. Radiological screenings and serological markers are effective methods of achieving early detection. Various surgical methods, including liver transplantation, and therapies such as radiofrequency lesioning and chemoembolization, are employed to treat this disease. However, due to limited donor availability and late diagnosis, treatment can be delayed. Tumour size, liver disease severity, and patient’s overall health are among the factors that influence the disease. Nanotechnology, a field that involves the precise manipulation of materials at the nanometer scale and the targeted delivery of therapeutic agents, presents a promising solution for HCC therapy. The utilization of nanoparticle-based therapies allows for the specific targeting of tumour-associated antigens, which enhances drug delivery and reduces drug-induced toxicity. Furthermore, nanomaterials such as carbon nanoparticles and biochemical sensors aid in the detection of oncological markers. Nanomedicine-based approaches possess the potential to revolutionize HCC therapy by improving drug delivery and targeting liver cancer stem cells. Specifically, targeted ligand-mediated therapy using saccharide or polysaccharide compounds, antibodies, peptides, and aptamers shows promise for liver-specific HCC treatment. Additionally, nanotherapy aimed at liver cancer stem cells (LCSCs) provides new possibilities to overcome the limitations of conventional treatments and improve patient outcomes. Ultimately, nanotechnology-based approaches hold great potential in enhancing the effectiveness of HCC therapy and offer new avenues for precision medicine in cancer treatment.
Femoral Preparation Before Head Dislocation in Hip Hemiarthroplasty for Fractured Neck of Femur Saves Time and Keeps the Acetabulum Clean of loose bone fragments: A Retrospective Study and Technical Report
Authors:   Senior Fellow, Orthopaedic Surgery, Mater University Hospital, Dublin, Ireland, Shaalan Mohamed , Lim Brandon ,   School of Medicine, Trinity College Dublin, Dublin, Ireland
Published: November 2023

Introduction: Femoral neck fractures are the most common traumatic injuries associated with increasing age and osteoporosis, occurring most in older females. The femoral neck is under constant strain from externally and internally generated forces, approximately 500 – 200 micro-strains from daily activities. Common causes are falls in the elderly and road traffic accidents in younger patients. There is a significant in-house mortality and one-year mortality rate associated with femoral fractures. Fractures can be classified using the Garden Classification or the 2018 AO/OTA classification. Management includes open reduction and internal fixation, cannulated or sliding screws and hemiarthroplasty or total hip arthroplasty. This study examines the benefits of femoral preparation before head dislocation in hip hemiarthroplasties by assessing differences between pre-operative and post-operative haemoglobin levels and surgical times. Methods: We report the surgical techniques of hip hemiarthroplasty where the femur is prepared before the femoral head is removed and the hip is reduced in the flexion position. A retrospective review of electronic patient records of patients who underwent hemiarthroplasties from June 2022 to June 2023 was conducted. Results: Surgical times for this surgical technique were 30 minutes faster than traditional methods while the differences in haemoglobin levels were minimal. Conclusion: Longer surgical times are associated with adverse events such as infections and wound dehiscence while increasing risks via surgeon fatigue and longer anaesthesia durations. Innovations in surgical techniques should thus aim to minimise surgical time without compromising procedures. This technique saves 30 min on average while having similar levels of blood loss to traditional techniques, maintaining standards, and not compromising on patient safety. Femoral preparation before dislocating the femoral head reduces the steps taken in leg repositioning which saves time and effort by the assistant. The reduction technique also avoids any risk of intra-operative iatrogenic fracture that can happen, especially if the assistant is a junior surgeon who lacks experience with hip reduction.

Published: November 2023

Due to their nature, court-issued restricted contact orders (consisting of orders that prohibit or limit contact between two or more persons) cause individuals named in such orders to experience disruption in their established social networks. The empirical literature highlights the disruptive element in social support networks as well as the harmful psychological outcomes for individuals who have been threatened or violated in intimate partner violence (IPV), domestic violence (DV), or sexual violence (SV) [1-3]. Another disruptive outcome of IPV, DV, and SV includes restricted court orders (RCOs). These orders that limit contact and communication between those who have offended and those who have been offended are thus, disruptive to social support networks especially when the parties involved are family members or otherwise intimately connected others. This disruption in social support may prevent needed resources for healing for those who have been offended by violence and those who have committed violent offenses. No literature exists that examines the potentially disruptive effects RCOs may have on the necessary social support systems (and changes in levels of perceived social support) of individuals who have violently offended or have been violently offended. This paper aims to add to the literature on the question of social support disruption in such cases, and to provide recommendations to mitigate support system interference for named parties in RCOs.
Jurisdiction of the International Criminal Court in the Hague and War Crimes in Ukraine in the Face of Security
Authors: Rynkun-Werner Robert , Kozicki Bartosz , Zelkowski Jarosław , Krzewniak Daria
Published: November 2023

War is theoretically subject to the laws of armed conflict but, in practice, it brings in its wake war crimes, crimes against humanity, genocide, and the crime of aggression. The parties to an armed conflict are unable and/or unwilling to hold the perpetrators of these crimes (oftentimes their own citizens) to account. Part of the rationale for establishment of the International Criminal Court was to offer a way forward in this regard. Yet the suspected war criminal – even the political leader of the aggressor state – must be apprehended and brought to The Hague so that he may face the Court. This is no easy task, thwarted by a variety of formal, factual, and political obstacles; all too often, the idea of a supranational justice system presided over by the International Criminal Court proves illusory, if not fictitious. In this article, these points are discussed in reference to the crimes being committed against the Ukrainian population by the Russian aggressors.
ASSESSMENT AND COMPARISON OF THE GAMMA AND BC TRANSITION MODELS FOR EXTERNAL FLOWS
Authors: KARABAY Sami , BARAN Özgür Ugras
Published: November 2023

Modelling of transition from the laminar to turbulent flow became a hot topic due to recent developments in renewable energy, UAV technologies and similar aerospace applications. The transition from laminar flow to turbulence is challenging to model in CFD analysis. The drag is overestimated if the transition is neglected in CFD solutions by assuming the flow is fully turbulent. This results in missing the fundamental characteristics of the flow and inaccurate predictions of the flow field. The most popular transition models are Menter's models applied to the SST turbulence model and the Baş-Çakmakçıoğlu (BC) transition model applied to the Spalart-Almaras model. We have focused on Menter's simpler but more popular γ model and Baş Çakmakçıoğlu models. The γ model relies on the local turbulence intensity, which makes applying the model challenging in external flows. This difficulty stems from the complex relationship between turbulence decay and transition onset. BC transition model utilizes the free stream turbulence intensity. Both models are verified using the Klebanoff and ERCOFTAC flat plate cases and several 2D external flow cases. Skin friction coefficient results are compared to experimental data. Results show that both models predict transition very similarly. BC model is computationally cheaper and easier to implement than the γ model. Also, γ model suffers from boundary conditions ambiguity.

Published: November 2023

O comércio internacional é um aspecto econômico de extrema importância para um país e isto não é diferente para o Brasil. Posto isto, os estados brasileiros buscam  meios de tornarem-se mais competitivos e obter mais operações de entrada  e saída de mercadoria no país. E um dos meios utilizados é a redução do Imposto sobre a Circulação de Mercadorias e Serviços (ICMS) em cada região. Nos últimos anos, diversos estados têm utilizado da redução da alíquota deste imposto a fim de atrair mais investimentos para seu território e tornar o processo de importação mais benéfico para as empresas, que têm aproveitado essas oportunidades para migrarem  para os estados que oferecem mais competitividade, visto que o valor dos impostos impacta também no valor do produto final e a forma em que este será comercializado. No ano de 2023, uma pauta que esteve em grande destaque foi a Reforma Tributária que foi levada ao plenário para votação. Tal reforma tem como objetivo diminuir a quantidade de impostos, inclusive o ICMS e é vista como um meio de finalmente acabar com essas guerras fiscais entre os estados. Entretanto, as consequências dessa Reforma compõem um fator intrigante que não deve ser ignorado.

Published: November 2023

Esta investigación examinó la posible relación entre las experiencias de vida adversas y la desadaptación social, sobre el riesgo de reincidencia sexual en adolescentes involucrados en prácticas sexuales abusivas. Mediante un enfoque cuantitativo se analizó a 115 adolescentes hombres en tratamiento especializado. Se emplearon tres instrumentos: Cuestionario de Comportamiento Social Adolescente (CACSA), Escala de Enganche Delictivo (EGED) y Escala de Tamizaje de Experiencias Adversas en la Infancia (EEA). El riesgo de reincidencia sexual se evaluó mediante The Estimate of Risk of Adolescent Sexual Offense Recidivism (ERASOR 2.0). Los resultados destacaron que los adolescentes presentaban un elevado número de experiencias adversas en la infancia, especialmente el grupo de alto riesgo. En términos de comportamiento, el grupo de alto riesgo mostró puntuaciones elevadas en conductas desadaptativas, mientras el grupo de riesgo bajo exhibió un comportamiento más prosocial. Respecto del comportamiento desadaptativo asociado a transgresión a la ley, el grupo de alto riesgo mostró valores más elevados. Se identificó que la presencia de infracción de ley general en estos adolescentes se relaciona con un mayor riesgo de reincidencia sexual. Se resalta la relevancia de un abordaje especializado y se subraya la necesidad de políticas públicas preventivas integrales para la violencia sexual en adolescentes.

Authors: Figueroa-Céspedes Ignacio
Published: November 2023

La identidad profesional docente es un concepto dinámico y múltiple que está estrechamente relacionado con aspectos de la identidad personal y la capacidad de agencia humana. Esta investigación busca describir experiencias de infancia y adolescencia, entendidas como huellas biográficas, reportadas por un grupo de ocho educadoras de párvulos chilenas en el contexto de la construcción de su identidad profesional docente. Se utiliza un método cualitativo de orientación biográfico-narrativa, desarrollado a partir de entrevistas semiestructuradas, journey plots y biogramas. Sobre dichos materiales se aplicó un análisis temático para agrupar las huellas biográficas. Los temas dan cuenta de experiencias relacionadas con: personas significativas, descuido/abandono, cuidado, la escuela y la vocación. En sus narrativas las educadoras reconocen el impacto de sus experiencias familiares, escolares y comunitarias tempranas en la formación de sus identidades docentes. La exploración de huellas biográficas mediante narrativas revela la estrecha conexión entre la vida personal y profesional, subrayando esta intersección clave para fortalecer la formación docente en educación infantil.

Published: November 2023

En México el café es un cultivo importante, aun sin ser originario de nuestro país forma parte de la cultura productiva de las regiones subtropicales. En la década pasada la cafeticultura estuvo inmersa en una fuerte crisis económica. Ante esta situación, en el sector cafetalero se implementaron algunas alternativas, entre éstas, el mejoramiento de la calidad del aromático y la producción de cafés diferenciados. En este contexto, la organización Campesinos Ecológicos de la Sierra Madre de Chiapas S. C. planteó que era necesario desarrollar una investigación que identificara las calidades y perfiles de sabor del café, con la finalidad de fortalecer su presencia en los mercados diferenciados. En el trabajo se utilizó la base de datos que integró el Departamento Técnico de la organización de productores en 2009 y se estructuró el procedimiento analítico. Mediante análisis de correlación, pruebas de t y de x2, se identificó que la variación térmica y las características del suelo afectan de manera significativa algunos atributos sensoriales del café (p<0.05). Se encontró que una cantidad importante de muestras tiene calificaciones mayores a 80.0 (escala de 0-100) y un perfil aromático a chocolate-caramelo. También se identificaron algunas notas de cítricos, florales y frutales, las cuales tienen potencial para diferenciar los perfiles de sabor de la bebida. Aunque a la fecha los precios del grano han mejorado de manera importante, es recomendable que los productores sigan atendiendo el mercado de los cafés diferenciados ya que en éste los precios pueden ser más estables en el mediano plazo.

Published: November 2023

El presente documento parte de información empírica de usuarios de agua potable en la comunidad de San Jerónimo Amanalco, Texcoco. Pretende mostrar cómo la teoría de sustentabilidad sistémica y el derecho al agua, enmarcados en lineamientos teórico-jurídicos, aportan elementos para la explicación y análisis de problemáticas ambientales englobadas en el sistema socioecológico. El trabajo inicia con la definición y aportes de la teoría de la sustentabilidad sistémica para después aplicarla al manejo de cuencas, vistas como reservorio de elementos necesarios para el ciclo del agua. Enseguida se plantea la problemática de la cuenca del Valle de México en la cual se muestra la falta de integración entre los distintos usos del agua. Se continúa con el aporte teórico de la Gestión Integral de los Recursos Hídricos (GIRH), reconociendo la necesidad de integrar los sistemas económico, social y ambiental para lograr la sustentabilidad desde un enfoque integrador. Después se busca relacionar las visiones teóricas con el fundamento jurídico del agua potable como derecho humano, ya que al retomarse el enfoque ecosociológico, la sociedad debe ser tomada en cuenta en cualquier iniciativa de manejo ambiental. Posteriormente, en el caso, se plantean las características de la comunidad como elementos constituyentes de la sustentabilidad, evidenciando la existencia de problemática ambiental y escasez de agua, por lo tanto el acceso al agua como derecho humano no se cumple.

Strategies for Mitigating Flood Risks in Western Region, Kenya
Authors: Opilo Betty Nasambu , Mugalavai Edward
Published: November 2023

The focus on strategies for mitigating flood risks is to identify which measures have been put in place to reduce flood risk using nature-based affordable approaches. It has been observed that there is a continuous increase in floods all over the world, in developed and developing countries, as a result of climate change. Floods have affected millions of people worldwide, leading to environmental, physical, economic, and social losses and reducing the growth of the nation. Disaster Risk Reduction (DRR) strategies have been rated among the best approaches for reducing natural hazard-related risks and setting the strategic direction for a sub-county, country, or region to become more resilient to hazards. However, the adoption level of the technology is still very low, creating a gap between the adoption of the technology and flood risk reduction. Dynamics in land use and cover have been increasing, thus enhancing flood risk in the western region of Kenya. This study therefore aimed at evaluating strategies for mitigating flood risks using a nature-based approach. The evaluation design was adopted, and both qualitative and quantitative data were utilized. A sample size of 384 was calculated using Fisher’s formula from a sample population of 63,025 households and Data was collected using questionnaires, interview schedules, and a focus group discussion guide. Secondary and quantitative data were analyzed using MS Excel and Statistical Package for Social Scientists (SPSS) version 26. Qualitative data was analyzed using narration techniques to support quantitative data, while quantitative data was presented using tables, graphs, and charts. The findings on the evaluation of the strategies for mitigating flood risks revealed that extension service as an informational strategy was 92% (353) of the best measure, whereas the existence of project meetings at 80% (307) benefited a lot from them. The study recommends the adoption of holistic management of the Sustainable Land Management Technologies (SLMT) policies and increased training areas to create environmental equity for sustainable development. The study is expected to assist in strengthening extension services with the involvement of both the county and the national government.

Abstract. The paper describes technical characteristics and presents first scientific results of a novel infrared imaging system (imager) for studies of nightglow emissions coming from hydroxyl (OH) and molecular oxygen (O2) layers in the mesopause region (80–100 km) above northern Scandinavia. The OH imager was put into operation in November 2022 at the Swedish Institute of Space Physics located in Kiruna (67.86° N, 20.42° E, 400 m altitude). The OH imager records selected emission lines in the OH (3-1) band near 1500 nm to obtain intensity and temperature maps at around 87 km altitude. Also, the OH imager registers infrared emissions coming from the O2 IR A-band airglow at 1268.7 nm in order to obtain O2 intensity maps at a slightly higher altitude around 94 km. This technique allows tracing wave disturbances both in horizontal and vertical domains in the mesopause region. Validation and comparison of the OH (3-1) rotational temperature with collocated lidar and Aura/MLS satellite temperatures are performed. First scientific results obtained with the OH imager for the first winter season (2022–2023) are discussed.
Efficient and Stable Coupling of the SuperdropNet Deep Learning-based Cloud Microphysics (v0.1.0) to the ICON Climate and Weather Model (v2.6.5)
Authors: Arnold Caroline , Sharma Shivani , Weigel Tobias , Greenberg David
Published: November 2023

Abstract. Machine learning (ML) algorithms can be used in Earth System models (ESMs) to emulate sub-grid-scale processes. Due to the statistical nature of ML algorithms and the high complexity of ESMs, these hybrid ML-ESMs require careful validation. Simulation stability needs to be monitored in fully coupled simulations, and the plausibility of results needs to be evaluated in suitable experiments. We present the coupling of SuperdropNet, a machine learning model for emulating warm rain processes in cloud microphysics, into ICON~2.6.5. SuperdropNet is trained on superdroplet simulations and predicts updates of the bulk moments for cloud and rain. It replaces the accretion, autoconversion, and self-collection of rain and cloud droplets in two-moment cloud microphysics. We address the technical challenge of integrating SuperdropNet, developed in Python and PyTorch, into ICON, written in Fortran, by implementing three different coupling strategies: embedded Python via the C Foreign Function Interface, pipes, and coupling of program components via YetAnotherCoupler (YAC). We validate the emulator in the warm bubble scenario and find that SuperdropNet runs stable within the experiment. In comparing experiment outcomes from the bulk moment scheme and SuperdropNet, we find that the results are physically consistent, and discuss differences that are observed for several diagnostic variables. In addition, we provide a quantitative and qualitative computational benchmark for three different coupling strategies—embedded Python, coupler YAC, and pipes—and find that embedded Python is a useful software tool for validating hybrid ML-ESMs.

Abstract. Landcover heterogeneity information considering soil wetness across the entire Arctic tundra is of interest for a wide range of applications targeting climate change impacts and ecological research questions. Patterns potentially link to permafrost degradation and affect carbon fluxes. First a landcover unit retrieval scheme which provides unprecedented detail by fusion of satellite data using Sentinel-1 (synthetic aperture radar) and Sentinel-2 (multispectral) has been adapted. Patterns of lakes, wetlands, general soil moisture conditions and vegetation physiognomy are represented at 10 m nominal resolution. Units with similar patterns are identified with a k-means approach and documented through statistics derived from comprehensive in situ records for soils and vegetation (more than 3500 samples). The result goes beyond the capability of existing landcover maps which have deficiencies in spatial resolution, thematic content and accuracy. Wetness gradients have been eventually assessed and measures for landscape heterogeneity were derived north of the treeline. About 40 % of the area north of the treeline falls into three units of dry types with limited shrub growth. Wetter regions have higher landcover diversity than drier regions. 45 % of the Arctic landscape is highly heterogeneous with respect to wetness considering 1kmx1km units (representative scale of frequently used regional landcover and permafrost modelling products). Wetland areas cover on average 9 % and moist tundra types 32 %, what is potentially of relevance for methane flux upscaling.

Abstract. Achieving climate targets requires mitigation against climate change, but also understanding of the response of land and ocean carbon systems. In this context, global soil carbon stocks and its response to environmental changes is key. This paper quantifies the global soil carbon feedback to changes in atmospheric CO2, and associated climate changes, for Earth system models (ESMs) in CMIP6. A standard approach is used to calculate carbon cycle feedbacks, defined here as soil specific carbon-concentration (βs) and carbon-climate (γs) feedback parameters. The sensitivity to CO2 is shown to dominate soil carbon changes at least up to a doubling of atmospheric CO2. However, the sensitivity of soil carbon to climate change is found to become an increasingly important source of uncertainty under higher atmospheric CO2 concentrations.
Effects of seasonal variations in vegetation and precipitation on catchment erosion rates along a climate and ecological gradient: insights from numerical modeling

Abstract. Precipitation in wet seasons influences catchment erosion and contributes to annual erosion rates. However, wet seasons are also associated with increased vegetation cover, which helps resist erosion. This study investigates the effect of present-day seasonal variations in rainfall and vegetation cover on erosion rates for four catchments along the extreme climate and ecological gradient (from arid to temperate) of the Chilean Coastal Cordillera (∼ 26–∼ 38∘ S). We do this using the Landlab–SPACE landscape evolution model to account for vegetation-dependent hillslope–fluvial processes and hillslope hydrology. Model inputs include present-day (90 m) topography and a time series (from 2000–2019) of MODIS-derived Normalized Difference Vegetation Index (NDVI) for vegetation seasonality, weather station observations of precipitation, and evapotranspiration obtained from Global Land Data Assimilation System (GLDAS) Noah. The sensitivity of catchment-scale erosion rates to seasonal average variations in precipitation and/or vegetation cover was quantified using numerical model simulations. Simulations were conducted for 1000 years (20 years of vegetation and precipitation observations repeated 50 times). After detrending the results for long-term transient changes, the last 20 years were analyzed. Results indicate that when vegetation cover is variable but precipitation is held constant, the amplitude of change in erosion rates relative to mean erosion rates ranges between 5 % (arid) and 36 % (Mediterranean setting). In contrast, in simulations with variable precipitation change and constant vegetation cover, the amplitude of change in erosion rates is higher and ranges between 13 % (arid) and 91 % (Mediterranean setting). Finally, simulations with coupled precipitation and vegetation cover variations demonstrate variations in catchment erosion of 13 % (arid) to 97 % (Mediterranean setting). Taken together, we find that precipitation variations more strongly influence seasonal variations in erosion rates. However, the effects of seasonal variations in vegetation cover on erosion are also significant (between 5 % and 36 %) and are most pronounced in semi-arid to Mediterranean settings and least prevalent in arid and humid–temperature settings.
Let me play, too! Co-designing inclusive sensory play spaces in collaboration with neurodiverse and neurotypical children
Authors:   , Kelly Shelly
Published: November 2023

This research investigated inclusive play spaces in the school environment from the perspective of the neurodiverse child in Brisbane, Australia. Co-design methods engaged children in creative workshops to explore what features supported their sensory and social inclusion in school play time. The purpose of the study was to enhance neurodiverse children’s agency, their future inclusion and wellbeing through greater involvement in school play, and their right to take part in future social discourse. Design principles were created that demonstrated benefits afforded to neurodiverse children when more supportive play features were considered.
Comparing the Effects of Static Stretching Alone and in Combination with Post-Activation Performance Enhancement on Squat Jump Performance at Different Knee Starting Angles

Published: November 2023

We aimed to investigate the impact of isolated static stretching (4 sets of 30 seconds) and its combined form with 10 repetitive drop jumps on lower limb performance during squat jumps at different knee joint starting angles (60°, 90°, and 120°). Thirteen participants completed three randomly ordered experimental visits, each including a standardized warm-up and squat jumps at three angles, apart from the intervention or control. Information was gathered through a three-dimensional movement tracking system, electromyography system, and force platform. The electromyography data underwent wavelet analysis to compute the energy values across the four wavelet frequency bands. The average power (Pavg), peak power (Ppeak), peak ground reaction force (GRFpeak), peak center of mass velocity (Vpeak), and force-velocity relationship at peak power (SFv) were extracted from the force and velocity-time data. The results revealed no significant influence of isolated static stretching, or its combined form with drop jumps, on the energy values across the frequency bands of the gastrocnemius, biceps femoris and rectus femoris, or the Pavg or Ppeak (P > 0.05). However, at 120°, static stretching reduced the GRFpeak (P = 0.001, d = 0.86) and SFv (P < 0.001, d = 1.12), and increased the Vpeak (P = 0.001, d = 0.5). The GRFpeak, Pavg, Ppeak, and SFv increased with an increase in the joint angle (P < 0.05), whereas the Vpeak decreased (P < 0.05). These findings suggest that static stretching does not diminish power output during squat jumps at the three angles; however, it alters GRFpeak, Vpeak, and the relative contributions of force and velocity to peak power at 120°, which can be eliminated by post-activation performance enhancement. Moreover, compared to 60° and 90°, 120° was more favorable for power and peak force output.
The Misrepresentation of Father-Daughter Incest in Neo-Victorianism on Screen: Misogynistic and Victim-Blaming Understandings of Gendered Violence in Penny Dreadful (2014-2016)
Authors: Pedro Dina
Published: November 2023

Incest has traditionally been regarded as the universal taboo, despite its convoluted and changeable nature from period to period –both in the social and legal arenas (Tate 2013). As a result, incest has proven to be a fascinating topic for authors across history, particularly in the case of Victorian and neo-Victorian Gothic fiction. We can find copious examples of incestuous relationships in (neo-)Victorian literature and culture, whose representation aims 1) to question idealised conceptualisations of the nuclear family, 2) to denounce sexual and domestic violence against women and 3) to cater to the audience’s morbid fascination for these forbidden relationships (Llewellyn 2010; Cox 2014). Penny Dreadful is a neo-Victorian TV series that exploits incest to seemingly denounce patriarchal and sexual violence. However, as I show in this article, the (mis)representation of its female protagonists, Lily and Vanessa –as a misandrist woman and a femme fatale, respectively–, might mislead the audience into victim blaming them for their own downfalls, rather than acknowledge their status as survivors of gender-based violence. Therefore, in spite of the series’ apparent feminist drive, Penny Dreadful ends up reproducing patriarchal ideologies that blame and silence the victim and side with the perpetrator.
Ontología negativa. Ecos de la mística eckhartiana del esse absolute en la egofanía idealista
Authors: Llamas Roig Vicente
Published: November 2023

La ontología negativa de Eckhart tendrá un profundo impacto en el idealismo alemán. No sólo la réplica a la distinción eriugeniana de naturalezas (naturans / naturata), también la idea de auto-revelación trinitaria parece prefigurar las bases de la fenomenología del espíritu. La Abgeschiedenheit, criba de peculiaridades del ser encauzada al esse absolutum (no-ser determinado), dejaría indeleble impronta en la parusía del Yo puro o en-sí, no contraído a yo empírico (no un ser omnímodo superior al yo inmanente sino su condición de posibilidad), y en la incepción de categorías autopoyéticas por interacción universal Yo / no-Yo con la que Fichte pretendiera conjurar la sombra del noúmeno kantiano. El Yo absoluto, al pensarse a sí en plena identidad consigo mismo (intuición de sí no objetivante, tesis sustentada en un principio de identidad auto-posicional) detona la antítesis a un no-Yo en demanda de una síntesis ulterior: Yo (transcendental) opongo en el Yo (conciencia) al Yo divisible (yo empírico) un no-Yo divisible (naturaleza). Yo empírico y naturaleza se limitarían mutuamente, mas la suspensión de esa recíproca determinación (lo que uno es, no lo es otro, dentro de una identidad, pues "uno es lo que otro no es") no revertiría la tesitura autogenética del Yo absoluto (autoconciencia), como la supresión de caracteres que alivia la tensión ontológica del esse proprium en la vía mística eckhartiana se orienta a la radical indeterminación del esse purum. Los dos niveles de racionalidad diferenciables en la antítesis dialéctica, teórico (en cuanto el yo está determinado por el no-yo: conocer es sentirse afectado por lo-otro, como si el no-yo limitase al yo; conocer lo-otro es su determinación sobre el yo, que construye a priori el no-yo para poder pensarlo como objeto) y práctico (en tanto el yo está determinado al no-yo) se disipan, restando la auto-conciencia (¿ipsum intelligere?). La apertura transcendental del yo a la alteridad, más allá de la inmediata auto-identidad ["la autoconciencia es en-sí y para-sí en cuanto que y porque es en-sí y para-sí para otra autoconciencia (gegenseitig anerkennen)", apunta Hegel], se nutre asimismo de ecos del ledic-sein. Este ensayo rastreará tangencias de mística renana e idealismo post-kantiano.
