    Spanish Heritage Speakers (HSs) in the U.S. can be the target of indirect acts of discrimination related to their ethnolinguistic identity (Ayón & Philbin, 2017). Name-based microaggressions are subtle insults directed at marginalized groups or individuals as a reaction, often unconscious or automatic, to their given name. This can include mispronunciation, renaming practices or indexical bleaching of an ethnic name (i.e., Bucholtz, 2005; Ayón & Philbin, 2017). Although it may seem harmless to a casual observer, students exposed to name-related subtle discrimination can experience feelings of othering, hyper-awareness, and unconscious internalization of harmful racial ideologies directed towards their ethnoracial group (i.e., Kohli & Solórzano, 2012; Ayón & Philbin, 2017; Bucholtz, 2016). Informed by Critical Race Theory and critical raciolinguistic scholarship, this study seeks to answer the following three questions: Do Spanish heritage speakers experience name-based microaggressions? What coping mechanisms do heritage speakers utilize to counteract name-based microaggressions in the educational setting? What specific strategies could be implemented in the SHL classroom to encourage student agency? To answer these questions, we surveyed a total of 95 college-age Spanish heritage speakers across the country. Participants were asked to complete an online Qualtrics questionnaire on their experiences with name-based microaggressions. This questionnaire consisted of eleven background questions adapted from the Bilingual Language Profile (Birdsong, Gertken & Amengual, 2012), and twelve critical questions about the topic under study. Furthermore, small focus groups and semi-structured interviews were conducted to expand on students’ coping mechanisms regarding name-related microaggressive experiences. In line with previous research, preliminary findings indicate that HSs often utilize avoidance, internalization, and assimilation strategies to fend off uncomfortable interactions or feelings of distress. Other coping mechanisms include choosing when and where to assert their ethnolinguistic identity, and when/where to adapt to other’s expectations of them. This study contributes to our understanding of Spanish heritage speakers’ racialized realities and raciolinguistic microaggressions in the learning environment

    In Silico Approaches and the Role of Ontologies in Aging Research

    The 2013 Rostock Symposium on Systems Biology and Bioinformatics in Aging Research was again dedicated to dissecting the aging process using in silico means. A particular focus was on ontologies, as these are a key technology to systematically integrate heterogeneous information about the aging process. Related topics were databases and data integration. Other talks tackled modeling issues and applications, the latter including talks focussed on marker development and cellular stress as well as on diseases, in particular on diseases of kidney and skin

    Understanding improved capacity retention at 4.3 V in modified single crystal Ni-rich NMC//graphite pouch cells at elevated temperature

    The capacity retention of commercially-sourced pouch cells with single crystal Al surface-doped Ni-rich cathodes (LiNi0.834Mn0.095Co0.071O2) is examined. The degradation-induced capacity fade becomes more pronounced as the upper-cut-off voltage (UCV) increases from 4.2 V to 4.3 V (vs. graphite) at a fixed cycling temperature (either 25 or 40 °C). However, cycles with 4.3 V UCV (slightly below the oxygen loss onset) show better capacity retention upon increasing the cycling temperature from 25 °C to 40 °C. Namely, after 500 cycles at 4.3 V UCV, cycling temperature at 40 °C retains 85.5% of the initial capacity while cycling at 25 °C shows 75.0% capacity retention. By employing a suite of electrochemical, X-ray spectroscopy and secondary ion mass spectrometry techniques, we attribute the temperature-induced improvement of the capacity retention at high UCV to the combined effects of Al surface-dopants, electrochemically resilient single crystal Ni-rich particles, and thermally-improved Li kinetics translating into better electrochemical performance. If cycling remains below the lattice oxygen loss onset, improved capacity retention in industrial cells should be achieved in single crystal Ni-rich cathodes with the appropriate choice of cycling parameter, particle quality, and particle surface dopants

    Large expert-curated database for benchmarking document similarity detection in biomedical literature search

    Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe
