Así en la tele como en la casa? Patronas y empleadas en la década del sesenta en Argentina
Rebekah E. Pite
Revista de Estudios Sociales , 2013,
Abstract: Over the course of the mid-twentieth century, Do a Petrona C. de Gandulfo established herself as Argentina's leading domestic expert. Her popularity reached new heights when she began broadcasting her cooking lessons on television with her assistant, Juanita Bordoy. This article explores the model of domestic work portrayed by these two women in comparison to that of other Argentine homemakers and their paid help during the 1960s by drawing from a broad base of sources that includes oral histories, television programming, magazines, and government and legal documents. Such evidence suggests that Do a Petrona and Juanita Bordoy's public interactions were both captivating and open to critique because they enabled others to observe a typically private domestic relationship during a period in which many women's relationships to domesticity and to paid work were in flux. This article argues that, to understand the tensions surrounding these changes, we must shift our framework and our terminology. While scholars of Latin America have tended towards casting domestic work relationships as paternalistic, the bonds of power and affection between Do a Petrona and Juanita Bordoy-and countless other domestic pairs-were (and continue to be) more maternalistic in nature.
Discriminating between the Effects of Founding Events and Reproductive Mode on the Genetic Structure of Triops Populations (Branchiopoda: Notostraca)
Rebekah L. Horn, Ralph Kuehn, Victoria Drechsel, David E. Cowley
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0097473
Abstract: Crustaceans that initially colonize a freshwater temporary pond can strongly bias the subsequent genetic composition of the population, causing nearby populations to be genetically distinct. In addition, these crustaceans have various reproductive modes that can influence genetic differentiation and diversity within and between populations. We report on two species of tadpole shrimp, Triops newberryi and Triops longicaudatus “short”, with different reproductive modes. Reproduction in the tadpole shrimp can occur clonally (parthenogenesis), with self fertilization (hermaphroditism), or through outcrossing of hermaphrodites with males (androdioecy). For all these reproductive modes, population genetic theory predicts decreased genetic diversity and increased population differentiation. Here we use mitochondrial control region (mtCR) sequences and nuclear microsatellite loci to determine if the difference in reproductive mode affects the high genetic structure typical of persistent founder effects. Previous authors indicated that T. newberryi is androdioecious because populations are composed of hermaphrodites and males, and T. longicaudatus “short” is hermaphroditic or parthenogenetic because males are absent. In our data, T. newberryi and T. longicaudatus “short” populations were highly structured genetically over short geographic distances for mtCR sequences and microsatellite loci (T. newberryi: ΦST = 0.644, FST = 0.252, respectively; T. l. “short”: invariant mtCR sequences, FST = 0.600). Differences between the two Triops species in a number of diversity measures were generally consistent with expectations from population genetic theory regarding reproductive mode; however, three of four comparisons were not statistically significant. We conclude the high genetic differentiation between populations is likely due to founder effects and results suggest both species are composed of selfing hermaphrodites with some level of outcrossing; the presence of males in T. newberryi does not appreciably reduce inbreeding. We cannot exclude the possibility that males in T. newberryi are non-reproductive individuals and the two species have the same mating system.

Family matters: The role of university museums in intergenerational learning
Rebekah Moran
University Museums and Collections Journal , 2009,
Abstract: Working within university museums in England, both museum educators and faculty staff are comfortable with pre-defined formal learning groups and subjects that ‘tie into the curriculum’. However, when engaging with ‘the wider community’ there is no curriculum and groups are self-selecting and ephemeral – so how do we design, market and map this kind of informal learning? One method of attracting informal or ‘free-choice’ learners is through the development of a family learning program. Such programs often represent a marketing coup and a boost to visitor figures but they also raise questions about style of delivery, modes of assessment and, most importantly, the validity of such learning within a university context. This paper discusses how family learning can meet university public engagement objectives and provide university students with key transferable skills through innovative ‘family learning volunteer’ programs. Finally, it illustrates that intergenerational learning is an important area of potential growth for university museums.
Don Quixote and Jesus Christ: The suffering “Idealists” of Modern Religion
Rebekah Marzhan
Oceánide , 2012,
Abstract: The figure of Don Quixote has always been seen as a character symbolizing the absurdity of idealistic pursuits. As such, countless generations have been able to temporally appropriate this medieval knight as representative of their own historical situation. Through a lineage of poetry, essays, novels, and scholarship, great thinkers have lifted the spirit of Quixote from Cervantes’ pages and revived the heralded knight of folly as a symbol of the incongruous place of not only faith in ideals but faith of a religious or spiritual nature in the modern, rational world. While this progression of thought has been well developed and explored through literary movements, modern illustrations of Don Quixote have been largely neglected in scholarship. Thus, to see how Don Quixote’s spirit has been revived visually in the twentieth century, scholars may turn to the work of Salvador Dalí. Through a series of illustrations for a 1945 edition of Quixote, Dalí utilizes the iconography of Jesus Christ to express Don Quixote as an irrational figure who suffers for his idealistic pursuits.
The Trouble with Inversion: an Examination of Science Sexual Orientation
Rebekah Johnston
Les Ateliers de l’éthique , 2008,
Abstract: Although some are excited about the possibility of using current scientific research into the biological causes of sexual orientation to ground rights claims, I argue that basing rights claims on this research is unwise because this research, specifically the hormonal, genetic, and structural research, is organized around the inversion assumption, a conceptual scheme within which some aspect of the biology of gay men and lesbians is thought to be inverted along sex lines.While there are many reasons to worry about the use of the inversion assumption, I focus on problems that arise from a further set of claims that must be assumed in order to make the use of the inversion assumption coherent. This further set of assumptions includes the claims (1) that heterosexuality is the standard state and that (2) this standard state is sexually-dimorphic and (3) deterministic. I argue that this set of assumptions is problematic because it results in ideological consequences that are both sexist and heterosexist. Plusieurs militants et militantes croient que la découverte d’un siège biologique de l’homosexualité permettra aux personnes homosexuelles de revendiquer leurs droits. Cependant, nous estimons qu’il est problématique de fonder ces revendications sur des recherches reposant sur certaines hypothèses qui sont implicites. En particulier, la notion d’inversion (inversion assumption) joue un r le clef dans ces recherches. Ce qui veut dire que le schème conceptuel qui cadre cette recherche scientifique suppose que certains traits des hommes et des femmes homosexuelles sont inversés. Donc, les males homosexuels jouent le r le de la femelle et les lesbiennes prennent celui du male dans la relation de couple. Pour que ce schème soit cohérent, plusieurs autres suppositions doivent être prises pour acquises et nous discutons trois d’entre-elles. En premier lieu, on suppose que l’hétérosexualité est la norme de base; deuxièmement que cette norme est dimorphe et finalement qu’elle est déterminée. Nous arguons que ces suppositions sont non seulement contestables mais qu’elles engendrent des idéologies à la fois sexistes et hétérosexistes.
Independent Searching During One-Shot Information Literacy Instruction Sessions: Is It
Rebekah Willson
Evidence Based Library and Information Practice , 2012,
Abstract: Objective – To test the assumption that giving students time to researchindependently during a one-shot information literacy instruction (ILI) session,combined with scaffolding, is an effective pedagogical practice and a good use ofclass time. Methods – The study was conducted at a student-focused, four-yearundergraduate institution with 8,500 full load equivalent students. Following brief,focused instruction in 10 different ILI sessions, first-, second-, and third-yearstudents in 80-minute one-shot ILI sessions were given time to researchindependently. The librarian and instructor were present to scaffold the instructionstudents received. Students were asked to track the research they did during classusing a research log and to fill out a short Web survey about their preparedness todo research and the usefulness of the ILI session. Results – Students agreed to have 83 research logs and 73 Web surveys included inthe study. Students indicated that they felt more prepared to do research for theirassignment after the ILI session and rated individual help from the librarian as themost useful aspect of the instruction session. Students did not rate independenttime to do research as valuable as anticipated. Examining the research logsindicated that several things are taking place during the ILI session, including thatstudents are demonstrating what was taught in the session in their searches, thattheir searches are progressing in complexity, and that students are using feedback from previous searches to inform the formulation of search queries. While students appear to be putting independent search time to good use, many students’ articulation of their thesis statement remains poor and searches continue to be fairly simplistic. Conclusions – This study gives evidence that giving independent research time in ILI sessions, with scaffolding, is an effective use of class time. The study also demonstrates that the majority of students are able to use what is taught during classes and that they are using class time effectively, though searching remains fairly simple. The focus of ILI sessions is on skill development, and future research should be on integrating IL into the curriculum to develop more complex skills and thinking needed in the research process.
On the tidal origin of hot Jupiter stellar obliquity trends
Rebekah Dawson
Physics , 2014, DOI: 10.1088/2041-8205/790/2/L31
Abstract: It is debated whether the two hot Jupiter populations --- those on orbits misaligned from their host star's spin axis and those well-aligned --- result from two migration channels or from two tidal realignment regimes. Here I demonstrate that equilibrium tides raised by a planet on its star can account for three observed spin-orbit alignment trends: the aligned orbits of hot Jupiters orbiting cool stars, the planetary mass cut-off for retrograde planets, and the stratification by planet mass of cool host stars' rotation frequencies. The first trend can be caused by strong versus weak magnetic braking (the Kraft break), rather than realignment of the star's convective envelope versus the entire star. The second trend can result from a small effective stellar moment of inertia participating in the tidal realignment in hot stars, enabling massive retrograde planets to partially realign to become prograde. The third trend is attributable to higher mass planets more effectively counteracting braking to spin up their stars. Both hot and cool star require a small effective stellar moment of inertia participating in the tidal realignment, e.g., an outer layer weakly coupled to the interior. I demonstrate via Monte Carlo that this model can match the observed trends and distributions of sky-projected misalignments and stellar rotation frequencies. I discuss implications for inferring hot Jupiter migration mechanisms from obliquities, emphasizing that even hot stars do not constitute a pristine sample.
