La aventura colectiva de mi feminismo. Apuntes sobre las experiencias de lxs estudiantes de Letras de la Universidad de Buenos Aires en torno a los estudios de género

Hay algo hermoso, inquietante, por momentos perturbador: resulta difícil encontrar dos licenciadxs en Letras, egresadxs de la Facultad de Filosofía y Letras (FFyL) de la Universidad de Buenos Aires (UBA), que hayan cursado exactamente la misma carrera. Incluso entre estudiantes que hayan seguido la misma orientación es poco probable que hayan asistido a los mismos seminarios, o incluso que hayan estudiado los mismos programas si cursaron iguales materias. Más allá de los debates abiertos sobre el plan de estudios y sobre los efectos “elige tu propia aventura”, aquí se plantea que una cursada en Letras es también una generación, un clima, por qué no una moda, una elección, una política. Cursé la Licenciatura y el Profesorado en Letras entre 2007 y 2013. Mi épica personal se fricciona con una hipótesis colectiva, con un ciclo abierto en 2003, que ha esbozado un nuevo país para ser joven, un nuevo ámbito de lo público, un nuevo escenario de profesionalización del docente investigador. En especial, fueron nuevos años –felices– para ser feminista.Fil: Angilletta, María Florencia. Universidad de Buenos Aires; Argentina.

An Exploration of the Benefits of Working as a Certified Peer Specialist (CPS) and Predictors of These Benefits

The mental health recovery movement has promoted the use of certified peer specialists (CPS) as an indispensable component of the recovery process when working with individuals with severe mental illnesses (SMI) (Solomon, 2004). In addition to assisting others, the literature indicates that the CPS may gain a shared benefit from the CPS experience (Solomon, 2004). The purpose of this study was to examine the benefits that working or volunteering as a CPS can have on the CPS’s personal recovery process and health care costs. Two benefits that were explored are a CPS’s service utilization (outpatient therapy, case management, and inpatient hospitalization) and financial entitlements (SSI, SSDI, and public assistance). This study investigated possible predictors of these benefits, such as demographics (gender, age, etc.), work setting (type of facility and population worked with), work environment (ability to make an impact, feeling supported and understood by supervisor and/or co-workers, etc.), and training factors (years certified, satisfaction with training, etc.) to determine if they correlate with reduced service utilization and/or financial entitlement. This study used a secondary data sample of 185 surveys that were previously administered to CPS in the Commonwealth of Pennsylvania. The findings can be used to further authenticate the CPS training and the CPS career path as a meaningful recovery resource. Strengths, limitations, potential implications, and explanations of the study’s outcomes are also explored

More oxygen during development enhanced flight performance but not thermal tolerance of Drosophila melanogaster

High temperatures can stress animals by raising the oxygen demand above the oxygen supply. Consequently, animals under hypoxia could be more sensitive to heating than those exposed to normoxia. Although support for this model has been limited to aquatic animals, oxygen supply might limit the heat tolerance of terrestrial animals during energetically demanding activities. We evaluated this model by studying the flight performance and heat tolerance of flies (Drosophila melanogaster) acclimated and tested at different concentrations of oxygen (12%, 21%, and 31%). We expected that flies raised at hypoxia would develop into adults that were more likely to fly under hypoxia than would flies raised at normoxia or hyperoxia. We also expected flies to benefit from greater oxygen supply during testing. These effects should have been most pronounced at high temperatures, which impair locomotor performance. Contrary to our expectations, we found little evidence that flies raised at hypoxia flew better when tested at hypoxia or tolerated extreme heat better than did flies raised at normoxia or hyperoxia. Instead, flies raised at higher oxygen levels performed better at all body temperatures and oxygen concentrations. Moreover, oxygen supply during testing had the greatest effect on flight performance at low temperature, rather than high temperature. Our results poorly support the hypothesis that oxygen supply limits performance at high temperatures, but do support the idea that hyperoxia during development improves performance of flies later in life

Violence on Social Media: An Exploration into the Online Expressions of Adolescents from Marginalized Areas of Greater Buenos Aires

This paper explores the online expressions of violence perpetrated or experienced by adolescents from marginalized areas of Greater Buenos Aires, Argentina. Four specific events-threats, "bondis" [fights], cyberbullying and grief-were examined using a qualitative methodology consisting of 20 in-depth interviews and 3,000 virtual observations of Facebook profiles. Among the main findings, most expressions of violence were found to be part of an offline-online dynamic. Based on the empirical evidence provided herein, it can be affirmed that these adolescents expressions of violence develop around the culture of "aguante" [fierce loyalty]. This paper ponders whether on the "like" platform, these expressions are implicitly utilitarian to the social network or. On the contrary, they enable displacements and meaningful reappropriations on the part of users. Ultimately, it poses new questions about the use of these tools by adolescents from marginalized areas and sets out to delve into the approaches used to examine these phenomena in all their complexity.

Intraspecific variation in thermal acclimation and tolerance between populations of the winter ant, Prenolepis imparis.

Thermal phenotypic plasticity, otherwise known as acclimation, plays an essential role in how organisms respond to short-term temperature changes. Plasticity buffers the impact of harmful temperature changes; therefore, understanding variation in plasticity in natural populations is crucial for understanding how species will respond to the changing climate. However, very few studies have examined patterns of phenotypic plasticity among populations, especially among ant populations. Considering that this intraspecies variation can provide insight into adaptive variation in populations, the goal of this study was to quantify the short-term acclimation ability and thermal tolerance of several populations of the winter ant, Prenolepis imparis. We tested for correlations between thermal plasticity and thermal tolerance, elevation, and body size. We characterized the thermal environment both above and below ground for several populations distributed across different elevations within California, USA. In addition, we measured the short-term acclimation ability and thermal tolerance of those populations. To measure thermal tolerance, we used chill-coma recovery time (CCRT) and knockdown time as indicators of cold and heat tolerance, respectively. Short-term phenotypic plasticity was assessed by calculating acclimation capacity using CCRT and knockdown time after exposure to both high and low temperatures. We found that several populations displayed different chill-coma recovery times and a few displayed different heat knockdown times, and that the acclimation capacities of cold and heat tolerance differed among most populations. The high-elevation populations displayed increased tolerance to the cold (faster CCRT) and greater plasticity. For high-temperature tolerance, we found heat tolerance was not associated with altitude; instead, greater tolerance to the heat was correlated with increased plasticity at higher temperatures. These current findings provide insight into thermal adaptation and factors that contribute to phenotypic diversity by revealing physiological variance among populations

Computerized structured cognitive training in patients affected by early-stage Alzheimer’s disease is feasible and effective: a randomized controlled study

Introduction. Alzheimer’s disease (AD) presents with significant neuropsychological deficits. Cognitive training in AD has recently started to demonstrate its efficacy. In this study we implemented computerized cognitive training of a large group of early-stage AD patients, to identify its effects at a neuropsychological level and to investigate whether they were stable after 6 months. Method. Eighty AD patients were randomized in two groups. Patients in the experimental group used a structured rehabilitative software three times a week for 12 consecutive weeks aimed at training memory, attention, executive function and language skills, whereas patients in the control group underwent a control intervention. Results. A Repeated Measures General Linear Model considering groups’ performance at the three assessment points (before training, after training, and at the 6-month follow-up) showed a significant interaction effect for: digit span forward (F(2,74) = 2.785, p = 0.03) and backward (F(2,74) = 3.183, p = 0.02), two-syllable words test (F(2,74) = 3.491, p = 0.004), Rivermead Behavioural Memory Test immediate (F(2,74) = 2.877, p = 0.03) and delayed (F(2,74) = 3.783, p = 0.003), Token test (F(2,74) = 4.783, p = 0.001), and Brixton test (F(2,74) = 8.783, p < 0.001). For all of them, experimental group performed better than controls. Conclusions. Patients in the experimental group showed a significant improvement in various neuropsychological domains, and their achievements were stable after 6 months. This study suggests an useful computerized training in AD, and should prompt further investigations about the generalizability of patients’ acquired skills to more ecologically-oriented tasks

Escritura y peronismo desde el género: apretar las teclas de la máquina

This article is organized based on the proposal that Peronism can be read as a “machine to make them write”, as a dynamization of writings and circulations of public words for women. This reading from the gender perspective makes it possible to crack the compartmentalization between politics and economy and show other available imaginations. In this line, texts by Blanca Luz Brum, Julia Prilutzky Farny, Alicia Eguren, Libertad Demitrópulos and Aurora Venturini are read which produce an archive of citizenships. The proposal of rereading a constellation of writings not so transited by critics tries to deploy the modulations of this typewriter beyond partidism referentiality, as ways of rewriting the common.Este artículo se organiza a partir de la apuesta de que el peronismo puede leerse como una “máquina de hacerlas escribir”, en tanto dinamización de las escrituras y circulaciones de las palabras públicas para las mujeres. Esta lectura de la imaginación disponible desde el género permite releer protocolos de la crítica que fisuren la compartimentalización entre política y economía. Así, se seleccionan textos de Blanca Luz Brum, Julia Prilutzky Farny, Alicia Eguren, Libertad Demitrópulos y Aurora Venturini que productivizan un archivo de ciudadanías. Desde este prisma, la propuesta de releer una constelación de escrituras menos transitada por la crítica intenta desplegar las modulaciones de esta máquina de escritura, más allá de la referencialidad partidaria, como formas de reescribir lo común

Spatial Dynamics of Nesting Behavior: Lizards Shift Microhabitats to Construct Nests with Beneficial Thermal Properties

Because temperature affects the growth, development, and survival of embryos,oviparous mothers should discriminate carefully among available nesting sites. We combined a radiotelemetric study of animal movements with a spatial mapping of environmental temperatures to test predictions about the nesting behavior of the eastern fence lizard (Sceloporus undulatus). Females made large excursions from their typical home ranges to construct nests in exposed substrates. These excursions appeared to be related solely to nesting because all females returned to forested habitat immediately afterward. On average, 1% (range ¼ 0–8%, n ¼ 19) of the area used by a female during nesting was contained within the area used before and after nesting. The selection of nesting sites matched predictions based on laboratory studies of embryonic performance; specifically, females nested in extremely open habitat at a mean of 6 cm depth. Spatial mapping of soil temperatures revealed that temperatures of nesting areas exceeded those of areas typically used by females, indicating that females preferred to construct warm nests that speed embryonic growth and development. However, this behavior could reduce the survivorship of females because of the need to rapidly navigate unfamiliar and exposed terrain

Ficciones argentinas desde el género: un archivo vivo

In Argentina, since 1983 languages have intermingled with the democratic return, lives and genders. In 1986, the first National Meeting of Women was held and in 2015, the «Ni Una Menos» movement. The last constitutional reform of 1994 includes shared patria potestad and quota law, which translates into the gradual conquest of civic equality. A year later, certain streams of novels cross these stories and modify the public imagination. A part of the sociability and production of these writers is through graphic journalism, teaching and the arts. In what ways do these narratives intervene in the debates and on the agenda? El affair Skeffington (María Moreno, 1992), Bajar es lo peor (Mariana Enríquez, 1995), Mudanzas (Hebe Uhart, 1995), El fin de la historia (Liliana Heker, 1996), ¿Vos me querés a mí? (Romina Paula, 2005), Me encantaría que gustes de mí (Dalia Rosetti, pseudonym for Fernanda Laguna, 2005) and El desperdicio (Matilde Sánchez, 2007). This article aims to analyze the ways in which these narratives reconfigure, from the middle of the nineties, the spaces of the State, the flows of work, money and recognition, and the politicization of life.En la Argentina, desde 1983 las lenguas se entremezclan con el retorno democrático, las vidas y los géneros.

Tecnologías de género ante el cáncer. Los casos de Barbie pelada y la negación de Lorde a la prótesis mamaria

Este artículo aborda las “tecnologías de género” ante el cáncer, mediante el planteo de dos ejes –los “pelos” y las “tetas”–. En cada uno se inscribe un caso testigo: la fabricación de muñecas peladas y la negación de Audre Lorde a las prótesis mamarias después de una mastectomía. Así, a partir de unas coordenadas teóricas que permiten pensar la problemática propuesta, se postula la siguiente hipótesis: la gestión del “pelo” y el régimen de visibilidad de las “tetas” funcionan como “tecnologías de género” frente a las cuales las cisenfermas de cáncer se conforman como subjetividades propicias para el despliegue de las “técnicas de normalización”. Ante esta dinámica, confluyen la reificación de la norma o la posibilidad de reagenciamiento resistente
