“’Chinese don’t drink coffee!’”: Coffee and Class Liminality in Elaine Mar’s Paper Daughter

This article offers a reading of the foodservice spaces in Elaine Mar’s memoir Paper Daughter in order to suggest changes in the way we think about class liminality. It argues that by focusing not just on the way the socially-mobile narrator experiences liminality, but also on the ways her working-class parents and co-workers experience it, we can begin to consider some of the complexities and nuances the idea of the liminal offers. In so doing, the article suggests a slightly new approach to thinking about and teaching Paper Daughter

Review of Genesea M. Carter and William H. Thelin’s Class in the Composition Classroom

Though community colleges enroll the majority of working-class college students, research on how to best serve the interests of working-class students at our institutions is limited. In Class in the Composition Classroom: Pedagogy and the Working Class, the contributors tackle the issue of supporting working-class students in college composition classes from several angles, offering practical pedagogical advice, guidance on college-wide initiatives, and research into common challenges faced by working-class students. While the text will be most valuable for those who teach writing, its insights apply to anyone who serves at a community college

Review of Flower Darby and James M. Lang’s Small Teaching Online: Applying Learning Science in Online Classes

In their 2019 book Small Teaching Online, Flower Darby and James M. Lang present a model for online instruction that uses what the authors call the “small teaching” approach, which posits that college faculty should look for small, high-impact changes they can make to their teaching practice in place of wholesale overhauls. The authors explore the unique challenges that online learners struggle with, from feeling disengaged to feeling overwhelmed by the demands of self-directed learning, then offer practical, sustainable solutions for each. Their text thus offers helpful teaching practices both for new online teachers and veterans

Catch me if you can: effectiveness and consequences of online copyright enforcement

We evaluate the unexpected shutdown of kino.to, a major platform for unlicensed video streaming in the German market. Using highly disaggregated clickstream data in a difference-in-differences setting, we compare the web behavior of 20,000 consumers in Germany and three control countries. We find that this intervention was not very effective in reducing unlicensed consumption or encouraging licensed consumption, mainly because users quickly switch to alternative unlicensed sites. We highlight that the shutdown additionally had important unintended externalities. Individuals who never visited kino.to and who additionally clicked on news articles that covered the shutdown increased their visits to piracy websites substantially. We show that this effect largely comes from articles that explicitly mention alternative websites or suggest that users do not have to fear legal consequences from unlicensed streaming. Finally, we document that the unlicensed video streaming market is much more fragmented after the shutdown, potentially affecting future interventions, at least in the short run.We argue that our results can be helpful to understand why online piracy rates are still high, despite a plethora of enforcement efforts.info:eu-repo/semantics/acceptedVersio

Hyperoctahedral Chen calculus for effective Hamiltonians

The algebraic structure of iterated integrals has been encoded by Chen. Formally, it identifies with the shuffle and Lie calculus of Lyndon, Ree and Sch\"utzenberger. It is mostly incorporated in the modern theory of free Lie algebras. Here, we tackle the problem of unraveling the algebraic structure of computations of effective Hamiltonians. This is an important subject in view of applications to chemistry, solid state physics, quantum field theory or engineering. We show, among others, that the correct framework for these computations is provided by the hyperoctahedral group algebras. We define several structures on these algebras and give various applications. For example, we show that the adiabatic evolution operator (in the time-dependent interaction representation of an effective Hamiltonian) can be written naturally as a Picard-type series and has a natural exponential expansion.Comment: Minor corrections. Some misleading notations and typos in the first version have been fixe

Translating ‘New Compactism’, circulation of knowledge and local mutations: Copenhagen’s Sydhavn as a case study

The international circulation of urban design concepts often leads to their characterization as transferable ideals defined by a set of universalized ‘best practices’ that are simply implemented in new localities, as is typical of top-down approaches to planning. Recently, the compact city and New Urbanism have become trendy concepts informing the development of urban projects across geographies. This research draws on ANT sensitivities and policy mobilities studies to examine the regeneration of Copenhagen’s Southern Harbour (Sydhavn) wherein the compact city and New Urbanism ideals, together with a declared inspiration from Dutch architecture, were originally incorporated in the masterplan. Through the analysis of documents and semi-structured interviews, the paper illustrates how these ideals–merged as \u27New Compactism\u27–were mobilized and re-intepreted by local actors in Sydhavn. It thus adds to our understanding of how the circulation of such ideals is not a matter of implementation, but a complex social process of translation that entails struggle and transformation

DESEMPENHO DE GENÓTIPOS DE ALFACEBABY LEAF SUBMETIDOS A SOLUÇÕES NUTRITIVAS EM CULTIVO PROTEGIDO (AGRONOMIA)

Introdução: A alface baby leaf é um produto recente e está em ascensão no Brasil, sendo uma hortaliça colhida precocemente para garantir tamanhos reduzidos, possuindo extrema qualidade e um ótimo valor nutricional, apresentando mais maciez e saborosidade do que as hortaliças colhidas no tempo convencional e possuem cores que variam do verde ao roxo. A alface é uma cultura extremamente exigente no que diz respeito à adubação. Neste trabalho o objetivo foi avaliar o desempenho de três diferentes genótipos de alface baby leaf submetidos a três diferentes soluções nutritivas. O esquema realizado no experimento foi em delineamento de blocos casualizados sob esquema fatorial. Ascultivares utilizadas são do tipo romana e ambas são cultivadas como baby leaf. Os parâmetros avaliados foram peso fresco da área foliar(PFF), peso seco da área foliar (PSF), peso fresco da raiz (PFR) e peso seco da raiz (PSR). As soluções utilizadas foram baseadas em uma solução para folhosas utilizada por pesquisadores da Embrapa Hortaliças, sendo que uma teve o valor de ferro dobrado e a outra recebeu o acréscimo de sódio em sua composição. Os parâmetros vegetativos dos genótipos de alface avaliados não sofreram melhorias causadas pelas diferentes formulações utilizadas, mas no caso da solução padrão + dobro de ferro houve um decréscimo no desenvolvimento radicular
