Published: May 2021

BackgroundAlthough the role of image-based AI in cancer research has been substantial, its impact on the clinical side has been limited so far. Physicians’ trust in AI, and its wider acceptability, has been significantly lower owing to its “black-box” nature, which raises liability questions concerning its use in the clinical context. MethodsTo comprehend the barriers in AI’s adoption, and to inform the future discourses in the human-centric and ethical design of AI, we designed and conducted semi-structured interviews with 7 imaging experts in the oncological domain. ResultsData saturation was achieved despite the small sample size, gathering concordant emerging needs and recommendations. Our findings demonstrate the divergent nature and focus of clinical and research practices, with differing AI needs. AI is afforded a peripheral, and yet a crucial role of a “decision help”, which can enable oncologists and related imaging specialists (i.e. radiologists, radiation-oncologists and nuclear medicine physicians) to push the boundaries of biological reasoning in treating cancers. Furthermore, our interviewees emphasized the need to embody ethics and liability in designing AI systems, and the development of educational opportunities for AI and cancer experts to enable an integrative vision of image-based AI. To this end, specific design guidelines are provided to inform both the Human-Centered Design and AI researchers in order to meaningfully address the contextually-sensitive concerns and challenges around the adoption of intelligent interactive technologies in cancer care. ConclusionsThe existing impact of AI in the clinical practices is limited as compared to the clinical research. In the future, AI is afforded a peripheral role of a ‘decision helper’ which might enable doctors to better understand the peculiarities and subtleties of cancers, and support them in developing novel treatment methods. Finally, in order to develop physicians’ trust in AI and its wider acceptability in clinical oncology, designers would have to address the ethical and liability concerns in relation to the use of AI systems.

Published: May 2021

Duchenne muscular dystrophy (DMD) is a genetic disease, which is associated to progressive skeletal muscle degeneration. In humans, DMD has early onset, causes developmental delays, and is a devastating disease that drastically diminishes the quality of life of the young individuals affected. The objective of this study was to evaluate the effects of a swimming protocol on memory and oxidative stress in an animal model of Duchenne muscular dystrophy. Male mdx and wild type mice within 28 days were used in this study. The animals were trained in a stepped swimming protocol for four consecutive weeks. It was verified that swimming was able to reduce significantly the levels of lipid peroxidation and protein carbonilation in gastrocnemius and hippocampus and striatum in exercised animals. Swimming has also prevented lipid peroxidation in diaphragm. Besides, this swimming protocol was able to increase free thiols in gastrocnemius, diaphragm and in all central nervous system structures. These results showed that a protocol of swimming as an aerobic exercise of low intensity, for four weeks, prevented aversive memory and habituation in mdx mice.
Double-barrel Free Fibula for Segmental Defect of Ulna and Radius: Case Report
Authors: Tripathy Satyaswarup , John Jerry R , Mangal Mayank
Published: May 2021

Introduction - Post traumatic complex defects of the forearm require multiple operations and prolonged rehabilitation. Segmental bony defects of the radius and ulna are occasionally seen as part of these complex wounds. There are a few options in bridging the skeletal defect. These include corticocancellous bone grafting, creation of a one bone forearm and vascularised fibula. Vascularised bone grafting is superior in an ischemic and fibrosed area as it enhances local blood supply. The fibula is usually used to bridge the defect in one bone i.e. the radius. Case presentation – A young male presented with an open comminuted fracture of radius and ulna following a crush injury to the left upper limb. The reconstruction was done in two stages – first a pedicled thoracoumbilical flap for soft tissue and in later stage a double barrel free fibula flap for segmental bone loss. Conclusion – The above approach offered the best chance of skeletal healing in a complex defect. The patient was able to gain reasonably good upper extremity function with the described technique.

Published: May 2021

The onset of the COVID-19 pandemic has led to an upsurge of discrimination against Asian American populations, and Filipinx Americans (FA) have reported high cases of perceived discrimination. Prior studies have shown a relationship between experiences of discrimination and poor mental health. The purpose of this study was to examine the association of perceived discrimination and psychological distress among FA living in Massachusetts from a survey collected during the COVID-19 pandemic (N = 133). Multiple regression analysis revealed that experiences of perceived discrimination were associated with psychological distress. Older participants were less likely to report psychological distress. Compared to men, womxn were more likely to report psychological distress. Our findings highlight the potential mental health consequences of perceived discrimination experienced by FA, which may have been exacerbated during the COVID-19 pandemic.

Authors: Dubey A. , Sonker A. , Chaudhary R.K.
Published: May 2021

Antibody titration is traditionally performed using a conventional test tube (CTT) method, which is subjected to interlaboratory variations because of a lack of standardization and reproducibility. The aim of this study is to compare newer methods such as gel column technology (GCT) and erythrocyte magnetized technology (EMT) for antibody titration in terms of accuracy and precision. Patient serum samples that contained immunoglobulin G (IgG) red blood cell (RBC) alloantibodies of a single specificity for Rh or K antigens were identified during routine transfusion service testing and stored. Titration and scoring were performed separately by different laboratory personnel on CTT, GCT, and EMT. Testing was performed a total of three times on each sample. Results were analyzed for accuracy and precision. A total of 50 samples were tested. Only 20 percent of samples tested with GCT showed titers identical to CTT, whereas 48 percent of samples tested with EMT showed titers identical to CTT. Overall, the mean of the titer difference from CTT was higher using GCT (+0.31) compared with that using EMT (+0.13). Precision shown by CTT was 30 percent, EMT was 76 percent, and GCT was 92 percent on repeat testing. GCT showed higher titer values in comparison with CTT but was found to be the most precise. EMT titers were comparable to CTT, and its precision was intermediate. Further studies to validate this method are required.

Authors: Ni Yufeng , Zhang Yujia , Zou Chong , Ding Li
Published: May 2021

A rapid and reproducible liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated to simultaneously determine sacubitril, valsartan and a metabolite of sacubitril (LBQ657) in human plasma using sacubitril-d4 and valsartan-d3 as the internal standards. Following protein precipitation, the analytes were operated on an Ultimate® XB-C18 column (2.1 × 50 mm, 3.5 μm, Welch) with a gradient elution with acetonitrile, and 5 mM ammonium acetate and 0.1% formic acid in water as the mobile phase. The detection was performed on a Triple Quad™ 4000 mass spectrometer coupled with an electrospray ionization source (ESI) under positive-ion multiple reaction monitoring mode. The linearities are 2.00-4000, 5.00-10000 and 5.00-10000 ng mL-1 for sacubitril, valsartan and LBQ657, respectively. The accuracy and precision of intra- and inter-day, dilution accuracy, recovery and stability of the method were all within the acceptable limits and no matrix effect or carryover was observed. The suitability of the method was successfully demonstrated in terms of the quantification of sacubitril, valsartan and LBQ657 in plasma samples collected from healthy Chinese volunteers in a clinical trial.
Oscillations of transonic flow past a symmetric profile with a blunt trailing edge
Authors: Kuzmin Alexander G.
Published: May 2021

We study the two-dimensional turbulent transonic flow past a symmetric profile with a blunt base and flat sides. The numerical simulation is based on the unsteady Reynolds-averaged Navier-Stokes equations. The obtained solutions reveal both symmetric and asymmetric oscillating flows past the profile at zero angle of attack. An occurrence of the symmetric or asymmetric flow regime depends on the time history of boundary conditions. A jet injection into the wake does not eliminate the flow non-uniqueness, though attenuates flow oscillations.
Development of sprung mass non-linear mathematical model of pitch dynamics with trailing arm suspension
Authors: Devesh M. , Manigandan R. , Banerjee Saayan , Mailan Lenin Babu
Published: May 2021

Military vehicles are required to negotiate drastic ride environments. Therefore, the vibration magnitudes which are transmitted to the vehicle chassis through the suspension system due to dynamic vehicle-terrain interactions, are usually large. Hence, it is necessary to study the vibrations that are transmitted to the sprung mass as it negotiates different types of terrain at different speeds. The present study is focused on the development of sprung mass non-linear pitch dynamics mathematical model of a military vehicle with a trailing arm torsion bar suspension system. The trailing arm kinematics and dynamics are incorporated into the non-linear governing equations of motion of the sprung and unsprung masses which consider the effects of sprung mass large pitch angular motions. The model is solved by coding in Matlab. The sprung mass non-linear pitch dynamics mathematical model is validated with an equivalent multi-body dynamics model which is developed by using MSC.ADAMS. This mathematical model would play a key role to fine-tune the vehicle and suspension parameters as well as comparatively evaluate the performance of the hydro-gas suspension system. The model can further be extended to include the military vehicle weapon recoil effects which can cause considerable magnitudes of vehicle pitch. Apart from simulating ride dynamics of the entire vehicle, the influence of movement with crane payload on the military recovery vehicle pitch dynamics can also be brought out as a useful extension of this mathematical model.

Performance enhancement of an automotive silencer using acoustic metamaterial baffles
Authors: Deery Daniel , Kennedy John
Published: May 2021

The potential for acoustic metamaterials to provide a breakthrough in sound attenuation has been unlocked in recent times due to advancements in additive manufacturing techniques. These materials allow the targeting of specific frequencies for sound attenuation. To date acoustic metamaterials have not been experimentally tested in an automotive silencer for performance enhancement. This study investigates the effect of acoustic metamaterials within a representative automotive silencer. These results are then compared with commonly used techniques in the silencer industry to gauge the effectiveness of the acoustic metamaterials. COMSOL simulations were used to validate the developed test rig and were compared to experimental results which were obtained using the two-load transmission loss test method. Through this testing method, the implementation of the acoustic labyrinthine DENORMS cylinder proved to be the most significant improvement in transmission loss within the silencer, with an increase in transmission loss of 40 dB at 1500 Hz. It was also found that the traditional hard wall internal baffle silencer performance can be improved by replacing it with a DENORMS internal baffle. Acoustic metamaterials have potential as a novel method for automotive companies to attenuate sound of specific frequencies.

Authors: Bellatreche Randha , Ouali Maamar , Balistrou Mourad , Tassalit Djilali
Published: May 2021

Nexus water/energy security is one of the main global challenges for the future generation. Solar distillation (thermal process) represents a sustainable solution to water shortages and energy crisis in the world especially in the Middle East and North Africa region. The technique is based on a evaporation–condensation process via heat delivery through a cylindrical parabolic collector to a thermal energy storage, in the form of sand integrated into the solar still, to maximize water production efficiencies. It is a technically feasible and operational method. Results suggest that the additional solar collector flux has a direct impact on the increase in average sand and seawater temperature particularly over the period between 12 p.m. and 4 p.m. Seawater temperature increases by >26.6%. The energy stored quantity delivered for the distiller basin grows proportionality with the sand temperature, which is depending directly for the solar collector absorber temperature. The difference between the both temperatures defines a decreasing rate of −19%. The daily water production by the hybrid solar distiller is 6.5 l/day, it represents an increase of +91% compared to the traditional concrete solar still production (3.4 l/day), for the same geometry and meteorological conditions.
Selective oxidation and direct decolorization of cationic dyes by persulfate without activation
Authors: Yang Bing , Luo Qiuping , Li Qinman , Meng Yuan , Lingli Li , Liu Yucheng
Published: May 2021

The aim of this work was to investigate the selective oxidation and direct decolorization of selected organic dyes (Methylene Blue (MB), Rhodamine B (RhB) and Orange II (OrgII)) by persulfate (PDS) without activation. Results show that the decolorization rate of MB was up to 58.0% within 10 minutes, while those of RhB and OrgII were only about 29.6% and 3.0% after 80 minutes, respectively. In comparison with the negligible impacts of pH from 2.0 to 9.0 on MB and OrgII decolorization, RhB decolorization rate obviously varied with the pH changes, and acid pH condition was beneficial for RhB decolorization. Quenching tests implied that the decolorization of dyes by PDS without activation was a nonradical oxidation process rather than sulfate radical oxidation. A plausible mechanism is that the decolorization process is attributed to the charged states of the dyes at different pH conditions, and thus direct electron transfer from dyes to PDS may occur, which is responsible for the bleaching of dyes. This study points out the potential bleaching capability of PDS without activation on cationic dyes, which may have important implications for selective oxidation treatment of dye wastewater.

Published: May 2021

The Bugisnese song lyrics use many methapors by their creators as expression forms of social reality. This study aims to describe the kinds of metaphors analyzed from the semantic cognitive aspect. The study is qualitative research. The study uses the semantic cognitive approach. Data sources are taken from Bugisnese song lyrics composed by Ancha Mahendra and Ansar S. from year 2000 to year 2010. Data collection procedures consist in reading and listening attentively then continued by note taking. After data collection, data are analyzed in the steps of data reduction, data presentation, and conclusion. The research results show that using of structural metaphors was more dominantly found in Bugisnese song lyrics than in orientational and ontology metaphors. Three kinds of metaphors are found; namely ten structural metaphors, one orientational metaphors, and four ontology metaphors. The use of structural metaphors is found more indicating that the song authors do not want to convey the lyrics purposes directly, but choose to transfer the purposes of song lyrics into concept of objects that have physical characteristics.Keywords: metaphor, song lyrics, Bugisnese song, semantic cognitiveMETAFORA DALAM LIRIK LAGU BUGIS: KAJIAN SEMANTIK KOGNITIFAbstrakLirik lagu Bugis banyak menggunakan metafora yang oleh penciptanya digunakan sebagai bentuk ekspresi penggambaran realitas sosial.

Analytical modelling of continuous fibre-reinforced thermoplastics’ thermomechanical properties and implementation into a failure model
Authors: Schramm Norbert , Teltschik Jan Xaver , Kroll Lothar
Published: May 2021

Mechanical properties of fibre-reinforced thermoplastics show a remarkable temperature dependence within application temperatures of automotive and aerospace lightweight structures. To take this dependence into account when designing components, the strengths (, , , , ) and stiffnesses (, , , , ) of continuous carbon and glass fibre-reinforced polyamide 6 and glass fibre-reinforced polypropylene are modelled analytically based on experiments. Data from temperature-controlled tests on flat samples in the range from -20 °C to +80 °C are therefore approximated using an extended hyperbolic approach. The models obtained are then evaluated based on their deviation from the experimental values. The main criterion of this evaluation is the reliable prediction of the temperature-dependent material properties while minimising the effort for generating test data and determining model parameters. Furthermore, the failure behaviour of the investigated materials under multiaxial mechanical and thermal stress is examined by implementing the determined strength curves into Cuntze’s physically based failure criterion.

Authors: Mottas Antoine , Lappi Veli-Matti , Sundström Johan , Neal Bruce , Mhurchu Cliona Ni , Löf Marie , Rådholm Karin
Published: May 2021

Background

Childhood obesity is a major public health issue. The increase in the consumption of foods with poor nutritional value, such as processed foods, contributes to this. Breakfast cereals are often advertised as a healthy way to start the day, but the healthiness of these products varies greatly.

Objective

Our main objective was to gather information about the nutritional characteristics of ready-to-eat breakfast cereals in Sweden and to investigate the healthiness of products targeted at children compared to other cereals by use of the FoodSwitch platform. A secondary objective was to evaluate the alignment between the Keyhole symbol and the Health Star Rating.

Methods

The FoodSwitch app is a mobile health (mHealth) tool used to present nutrition data and healthier alternative products to consumers. Ready-to-eat breakfast cereals from the largest Swedish grocery retailers were collected using the FoodSwitch platform. Products were defined as targeting children if they presented features addressing children on the package.

Results

Overall, information on 261 ready-to-eat cereals was examined. Of this total, 8% (n=21) were targeted at children. Child-targeted cereals were higher in sugar (22.3 g/100 g vs 12.8 g/100 g, P<.001) and lower in fiber (6.2 g/100 g vs 9.8 g/100 g, P<.001) and protein (8.1 g/100 g vs 10.5 g/100 g, P<.001). Total fat (3 g/100 g vs 10.5 g/100 g, P<.001) and saturated fat (0.8 g/100 g vs 2.6 g/100 g, P<.001) were also lower. No difference was found in salt content (P=.61). Fewer child-targeted breakfast cereals displayed an on-pack Keyhole label (n=1, 5% vs n=53, 22%; P=.06), and the mean Health Star Rating value was 3.5 for child-targeted cereals compared to others (mean 3.8, P=.07). A correlation was found between the Keyhole symbol and the Health Star Rating.

Conclusions

Ready-to-eat breakfast cereals targeted at children were less healthy in terms of sugar and fiber content compared to products not targeted at children. There is a need to improve the nutritional quality of child-targeted cereals.

Authors: Ferreira Gabriel Ferraz , Quiles Marcos Gonçalves , Nazaré Tiago Santana , Rezende Solange Oliveira , Demarzo Marcelo
Published: May 2021

Background

A systematic review can be defined as a summary of the evidence found in the literature via a systematic search in the available scientific databases. One of the steps involved is article selection, which is typically a laborious task. Machine learning and artificial intelligence can be important tools in automating this step, thus aiding researchers.

Objective

The aim of this study is to create models based on an artificial neural network system to automate the article selection process in systematic reviews related to “Mindfulness and Health Promotion.”

Methods

The study will be performed using Python programming software. The system will consist of six main steps: (1) data import, (2) exclusion of duplicates, (3) exclusion of non-articles, (4) article reading and model creation using artificial neural network, (5) comparison of the models, and (6) system sharing. We will choose the 10 most relevant systematic reviews published in the fields of “Mindfulness and Health Promotion” and “Orthopedics” (control group) to serve as a test of the effectiveness of the article selection.

Results

Data collection will begin in July 2021, with completion scheduled for December 2021, and final publication available in March 2022.

Conclusions

An automated system with a modifiable sensitivity will be created to select scientific articles in systematic review that can be expanded to various fields. We will disseminate our results and models through the “Observatory of Evidence” in public health, an open and online platform that will assist researchers in systematic reviews.

Constructing High-Fidelity Phenotype Knowledge Graphs for Infectious Diseases With a Fine-Grained Semantic Information Model: Development and Usability Study
Authors: Deng Lizong , Chen Luming , Yang Tao , Liu Mi , Li Shicheng , Jiang Taijiao
Published: May 2021

Background

Phenotypes characterize the clinical manifestations of diseases and provide important information for diagnosis. Therefore, the construction of phenotype knowledge graphs for diseases is valuable to the development of artificial intelligence in medicine. However, phenotype knowledge graphs in current knowledge bases such as WikiData and DBpedia are coarse-grained knowledge graphs because they only consider the core concepts of phenotypes while neglecting the details (attributes) associated with these phenotypes.

Objective

To characterize the details of disease phenotypes for clinical guidelines, we proposed a fine-grained semantic information model named PhenoSSU (semantic structured unit of phenotypes).

Methods

PhenoSSU is an “entity-attribute-value” model by its very nature, and it aims to capture the full semantic information underlying phenotype descriptions with a series of attributes and values. A total of 193 clinical guidelines for infectious diseases from Wikipedia were selected as the study corpus, and 12 attributes from SNOMED-CT were introduced into the PhenoSSU model based on the co-occurrences of phenotype concepts and attribute values. The expressive power of the PhenoSSU model was evaluated by analyzing whether PhenoSSU instances could capture the full semantics underlying the descriptions of the corresponding phenotypes. To automatically construct fine-grained phenotype knowledge graphs, a hybrid strategy that first recognized phenotype concepts with the MetaMap tool and then predicted the attribute values of phenotypes with machine learning classifiers was developed.

Results

Fine-grained phenotype knowledge graphs of 193 infectious diseases were manually constructed with the BRAT annotation tool. A total of 4020 PhenoSSU instances were annotated in these knowledge graphs, and 3757 of them (89.5%) were found to be able to capture the full semantics underlying the descriptions of the corresponding phenotypes listed in clinical guidelines. By comparison, other information models, such as the clinical element model and the HL7 fast health care interoperability resource model, could only capture the full semantics underlying 48.4% (2034/4020) and 21.8% (914/4020) of the descriptions of phenotypes listed in clinical guidelines, respectively. The hybrid strategy achieved an F1-score of 0.732 for the subtask of phenotype concept recognition and an average weighted accuracy of 0.776 for the subtask of attribute value prediction.

Conclusions

PhenoSSU is an effective information model for the precise representation of phenotype knowledge for clinical guidelines, and machine learning can be used to improve the efficiency of constructing PhenoSSU-based knowledge graphs. Our work will potentially shift the focus of medical knowledge engineering from a coarse-grained level to a more fine-grained level.
Mapping Information Needs of Patients With Sexually Transmitted Infections Using Web-Based Data Sources: Grounded Theory Investigation (Preprint)

BACKGROUND

According to the World health organization (WHO), more than 1 million sexually transmitted infections (STIs) are acquired each day across the world. The incidence rates of STIs in the United States are at a record high for the fourth consecutive year. Owing to the stigma associated with the incidence of STI, there is a general reluctance to seek information in person. Instead, web-based information sources remain the primary avenues of information-seeking. However, these sources are designed without a comprehensive understanding of the information needs of individuals who have contracted STIs.

OBJECTIVE

This study aimed to investigate the information needs of individuals who have or suspect they have contracted an STI. A better understanding of their information needs can drive the design of more effective digital interventions.

METHODS

This is a qualitative and analytical study of 549 transcripts (consisting of queries posted over the last 10 years) from web-based forums of the American Sexual Health Association (ASHA), which allows patients, volunteers, and health care providers connect anonymously. The analysis follows a grounded theory (GT) approach with multiple coding stages to uncover categories and themes.

RESULTS

Three categories of information needs emerged. The first two, clinical and logistical, are similar to other contexts. However, our analysis shows that there is a significant need for the last category—psychosocial information. Approximately 59% of instances are linked to concerns such as confusion, discretion, remorse, and others. These needs vary across the stages of a patient’s journey from symptom manifestation to treatment maintenance.

CONCLUSIONS

Responding to the needs of individuals who have or suspect they have contracted an STI requires compassionate and personalized responses (beyond factual clinical and logistical information). Web-based forums provide anonymity but do not adequately incorporate mechanisms, practices, or incentives to respond to diverse psychosocial concerns. Innovative approaches to add such support can make the digital interventions more effective for this group of individuals.

As technology has developed rapidly nowadays, it arises some impacts. Controlling electronic devices using the smart home application can ease users to control household electronic equipment to reduce el,ectricity wastefulness when the users forget to turn them off. Towards the aim, the author conducted research on the energy efficiency of lamps used in Internet of Things (IoT) technology.The research developed a controlling system (on-off) of 5 arduino-based LED lamps. The website would control the LED lamps which will send data to the server where the server will continue the data to arduino to read the command: ON or OFF. Next, arduino will send the LED’s status to the server to perform the LED status display on the website. Blackbox testing is used to better utilize the functional aspects of the system designed for users’ convenience in controlling LED lamps based on the appearance of the website. Therefore, the system can show that the functions of both hardware and website controlling the LED lamps are running well and can be used by users easily and usefully.

Hybrid Power Plant is an integration of two or more power plants based on renewable energy or not. Indonesia targets 23% of new renewable energy in the national energy mix in 2025, Merden Village is one of the areas located in Padureso District, Kebumen Regency., which has a renewable energy-based power plant, namely PLTMH with a capacity of 2x200 kVa connected to the grid (PLN). However, from August to December it did not run optimally due to a lack of water supply from the Wadaslintang Reservoir. Based on the database form NASA, the village of Merden is an area that has radiation of 4,60 kWh/m2/day, with a high enough intensity, this village has the potential to be paired with photovoltaics as additional energy. This research uses the help of HOMER software with the parameters entered, among others, energy source (solar radiation intensity and water discharge), equipment specifications, cost and daily load profile. The results of this study are the electrical energy production of the two generators is 1.301.169 kWh per year with a total NPC value of -$941.597 and an LCOE of - $0,056. The most optimal configuration is Microhydro 385 kW, PV 15kW, Battery 40 units, Bi-Directional Inverter 75 kW. This shows the additional of PV can be a reference because it can produce electrical energy for one full year.Keywords : Hybrid, Microhydro, PV, Grid, HOMER

lente feminista de la desigualdad económica
Authors: Marchina Stefania Tapia
Published: May 2021

La etapa neoliberal del capitalismo ha acentuado las desigualdades económicas a través de la implementación de reformas legislativas e institucionales específicas. Estas han permitido elevar los márgenes de acumulación mediante la reestructuración de los mercados laborales y la reducción de la participación del Estado en la provisión de bienestar. Leer estos cambios a la luz del feminismo incorpora un análisis complejo de las interrelaciones entre el género y la economía que visibiliza el protagonismo de las mujeres en las dinámicas de ajuste, particularmente ante condiciones laborales precarizadas y la reducción de las redes de seguridad social.
Hacia una nueva metafísica del género
Authors: Mc Manus Siobhan Guerrero
Published: May 2021

El presente texto elabora una propuesta novedosa en torno a qué es el género. Para ello, realiza una crítica a diversos modelos metafísicos en torno a este que han ido ganando influencia al interior de la filosofía feminista anglosajona. De manera sucinta, se evalúan estos modelos a la luz de dos controversias que hoy atraviesan los feminismos: A) ¿debe el feminismo ser abolicionista de género?, y B) ¿reifica la identidad de género a los roles de género? La hipótesis de este texto consiste en señalar que los sesgos funcionalistas de los modelos criticados los llevan a prejuzgar estas cuestiones ignorando en el proceso otros aspectos asociados al género. Para evitar esta desafortunada consecuencia, este texto concluye retomando elementos de diversas filosofías feministas que permiten una concepción más compleja de qué es el género.
archivo de sentimentos
Authors: Hernández Galván Francisco
Published: May 2021

Un archivo de sentimientos es una vorágine emocional. Una forma de entender políticamente las emociones con raíces culturales, ubicadas en tramas espaciales y desenlaces subjetivos. Ann Cvetkovich (filosofa feminista y directora del Instituto Pauline Jewett de Estudios de la mujer y género en la Universidad de Carleton, Ottawa) comienza la argumentación de su singular archivo explicando una serie de dificultades individuales —una ruptura afectiva, un cambio en la identidad sexual, una tesis en proceso de escritura— para mostrar la profunda imbricación de la vida académica con su vida personal y la necesaria incorporación de la experiencia en la reflexión epistémica.
