MICK: A Meta-Learning Framework for Few-shot Relation Classification with Small Training Data

Few-shot relation classification seeks to classify incoming query instances after meeting only few support instances. This ability is gained by training with large amount of in-domain annotated data. In this paper, we tackle an even harder problem by further limiting the amount of data available at training time. We propose a few-shot learning framework for relation classification, which is particularly powerful when the training data is very small. In this framework, models not only strive to classify query instances, but also seek underlying knowledge about the support instances to obtain better instance representations. The framework also includes a method for aggregating cross-domain knowledge into models by open-source task enrichment. Additionally, we construct a brand new dataset: the TinyRel-CM dataset, a few-shot relation classification dataset in health domain with purposely small training data and challenging relation classes. Experimental results demonstrate that our framework brings performance gains for most underlying classification models, outperforms the state-of-the-art results given small training data, and achieves competitive results with sufficiently large training data

Aspirational Eating: Class anxiety and the Rise of Food in Popular Culture

This dissertation focuses on four pillars in the popular discourse about food 1) sophistication, 2) thinness, 3) purity, and 4) cosmopolitanism. The collective emergence of these four pillars in mainstream U.S. culture in the 1980s has been called the American “food revolution.” The prevailing explanation for the food revolution is a progressive narrative I refer to as the “culinary enlightenment thesis.” According to that thesis, the four pillars represent a unified gestalt that resulted from the inevitable forward march of progress in agricultural technologies, nutritional science, global trade, and liberal multiculturalism. I show that the four pillars are neither a unified gestalt nor a new phenomenon. Instead, they represent conflicting and competing ideals that were also mainstream preoccupations between 1880 and 1920. At the turn of the twentieth century, gourmet cooking, slimming diets, natural and “Pure Foods,” and international cuisines first became popular in the U.S. primarily among urban middle-class women, who served as national taste leaders. Furthermore, I analyze how recent mass media discourses and texts, including representations of President Obama, the Grey Poupon Rolls Royce advertising campaign, NBC's hit reality series “The Biggest Loser,” and critically-acclaimed films like Ratatouille (Pixar 2007) Sideways (Fox Searchlight 2004) construct, negotiate with, and reinforce the four pillars of “enlightened” eating. My central argument is that rather than representing a true enlightenment, the food revolution serves as a compensatory form of class mobility for the American middle class during periods of income stagnation and high inequality. Food has been used to define social classes since the emergence of capitalism, but aspirational eating, or the use of food as a means of performing and embodying the “good life” is a quintessentially middle-class practice that emerged in Anglo-American culture in the eighteenth century. Its changing manifestations reflect the shifting nature of middle-class status anxieties. Since the 1980s, as middle class has struggled to maintain their material advantages over the lower classes, the cultural capital represented by food has become a central technology of creating class distinctions and one of the primary ways that many Americans have of aspiring to the “good life.”Ph.D.American CultureUniversity of Michigan, Horace H.

Peering through the Dust: NuSTAR Observations of Two FIRST-2MASS Red Quasars

Some reddened quasars appear to be transitional objects in the merger-induced black hole growth/galaxy evolution paradigm, where a heavily obscured nucleus starts to be unveiled by powerful quasar winds evacuating the surrounding cocoon of dust and gas. Hard X-ray observations are able to peer through this gas and dust, revealing the properties of circumnuclear obscuration. Here, we present NuSTAR and XMM-Newton/Chandra observations of FIRST-2MASS selected red quasars F2M 0830+3759 and F2M 1227+3214. We find that though F2M 0830+3759 is moderately obscured (N_(H,Z) = 2.1 ± 0.2 × 10^(22) cm^(−2)) and F2M 1227+3214 is mildly absorbed (N_(H,Z) = 3.4^(+0.8)_(−0.7) × 10^(21) cm^(−2)) along the line-of-sight, heavier global obscuration may be present in both sources, with N_(H,S) = 3.7^(+4.1)_(−2.6) × 10^(23) cm^(−2) and < 5.5 × 10^(23) cm^(−2), for F2M 0830+3759 and F2M 1227+3214, respectively. F2M 0830+3759 also has an excess of soft X-ray emission below 1 keV which is well accommodated by a model where 7% of the intrinsic AGN X-ray emission is scattered into the line-of-sight. While F2M 1227+3214 has a dust-to-gas ratio (E(B − V )/N_H) consistent with the Galactic value, the E(B−V )/NH value for F2M 0830+3759 is lower than the Galactic standard, consistent with the paradigm that the dust resides on galactic scales while the X-ray reprocessing gas originates within the dust-sublimation zone of the broad-line-region. The X-ray and 6.1μm luminosities of these red quasars are consistent with the empirical relations derived for high-luminosity, unobscured quasars, extending the parameter space of obscured AGN previously observed by NuSTAR to higher luminosities

A students-as-partners-inspired approach to assessment rubric design

The global popularity of the students-as-partners (SaP) model in the higher education sector demonstrates that students, through their lived experiences, have valuable perspectives to contribute to shaping university curricular and co-curricular experiences. While there are numerous inherent benefits associated with facilitating SaP arrangements, incorporating such practices to influence curricular change can be difficult in highly regulated and accredited courses. This article presents a successfully trialled SaP-inspired model involving assessment rubric design in the Bachelor of Laws degree offered at Curtin University in Australia, which is subject to multiple layers of regulation at national and state levels by public and private bodies. The SaP-inspired model presented in the paper is a useful starting point for academics wanting to engage in SaP co-creation of curricular initiatives in contexts that are not especially conducive to SaP, for example, heavily regulated and accredited courses. This article further contributes to existing SaP literature as it presents qualitative and quantitative data collected from the students who engaged in the SaP-inspired model, as well as data collected from students who experienced the SaP-inspired outputs first hand. This article commences with a student reflection on the SaP-inspired model, written by Ryan Kirby who participated in the workshop and assisted in the creation of the assessment rubric and supplementary materials

Impacts of the Tropical Pacific/Indian Oceans on the Seasonal Cycle of the West African Monsoon

The current consensus is that drought has developed in the Sahel during the second half of the twentieth century as a result of remote effects of oceanic anomalies amplified by local land–atmosphere interactions. This paper focuses on the impacts of oceanic anomalies upon West African climate and specifically aims to identify those from SST anomalies in the Pacific/Indian Oceans during spring and summer seasons, when they were significant. Idealized sensitivity experiments are performed with four atmospheric general circulation models (AGCMs). The prescribed SST patterns used in the AGCMs are based on the leading mode of covariability between SST anomalies over the Pacific/Indian Oceans and summer rainfall over West Africa. The results show that such oceanic anomalies in the Pacific/Indian Ocean lead to a northward shift of an anomalous dry belt from the Gulf of Guinea to the Sahel as the season advances. In the Sahel, the magnitude of rainfall anomalies is comparable to that obtained by other authors using SST anomalies confined to the proximity of the Atlantic Ocean. The mechanism connecting the Pacific/Indian SST anomalies with West African rainfall has a strong seasonal cycle. In spring (May and June), anomalous subsidence develops over both the Maritime Continent and the equatorial Atlantic in response to the enhanced equatorial heating. Precipitation increases over continental West Africa in association with stronger zonal convergence of moisture. In addition, precipitation decreases over the Gulf of Guinea. During the monsoon peak (July and August), the SST anomalies move westward over the equatorial Pacific and the two regions where subsidence occurred earlier in the seasons merge over West Africa. The monsoon weakens and rainfall decreases over the Sahel, especially in August.Peer reviewe

Severe early onset preeclampsia: short and long term clinical, psychosocial and biochemical aspects

Preeclampsia is a pregnancy specific disorder commonly defined as de novo hypertension and proteinuria after 20 weeks gestational age. It occurs in approximately 3-5% of pregnancies and it is still a major cause of both foetal and maternal morbidity and mortality worldwide1. As extensive research has not yet elucidated the aetiology of preeclampsia, there are no rational preventive or therapeutic interventions available. The only rational treatment is delivery, which benefits the mother but is not in the interest of the foetus, if remote from term. Early onset preeclampsia (<32 weeks’ gestational age) occurs in less than 1% of pregnancies. It is, however often associated with maternal morbidity as the risk of progression to severe maternal disease is inversely related with gestational age at onset2. Resulting prematurity is therefore the main cause of neonatal mortality and morbidity in patients with severe preeclampsia3. Although the discussion is ongoing, perinatal survival is suggested to be increased in patients with preterm preeclampsia by expectant, non-interventional management. This temporising treatment option to lengthen pregnancy includes the use of antihypertensive medication to control hypertension, magnesium sulphate to prevent eclampsia and corticosteroids to enhance foetal lung maturity4. With optimal maternal haemodynamic status and reassuring foetal condition this results on average in an extension of 2 weeks. Prolongation of these pregnancies is a great challenge for clinicians to balance between potential maternal risks on one the eve hand and possible foetal benefits on the other. Clinical controversies regarding prolongation of preterm preeclamptic pregnancies still exist – also taking into account that preeclampsia is the leading cause of maternal mortality in the Netherlands5 - a debate which is even more pronounced in very preterm pregnancies with questionable foetal viability6-9. Do maternal risks of prolongation of these very early pregnancies outweigh the chances of neonatal survival? Counselling of women with very early onset preeclampsia not only comprises of knowledge of the outcome of those particular pregnancies, but also knowledge of outcomes of future pregnancies of these women is of major clinical importance. This thesis opens with a review of the literature on identifiable risk factors of preeclampsia

Measurements of the pp → ZZ production cross section and the Z → 4ℓ branching fraction, and constraints on anomalous triple gauge couplings at √s = 13 TeV

Four-lepton production in proton-proton collisions, pp -> (Z/gamma*)(Z/gamma*) -> 4l, where l = e or mu, is studied at a center-of-mass energy of 13 TeV with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 35.9 fb(-1). The ZZ production cross section, sigma(pp -> ZZ) = 17.2 +/- 0.5 (stat) +/- 0.7 (syst) +/- 0.4 (theo) +/- 0.4 (lumi) pb, measured using events with two opposite-sign, same-flavor lepton pairs produced in the mass region 60 4l) = 4.83(-0.22)(+0.23) (stat)(-0.29)(+0.32) (syst) +/- 0.08 (theo) +/- 0.12(lumi) x 10(-6) for events with a four-lepton invariant mass in the range 80 4GeV for all opposite-sign, same-flavor lepton pairs. The results agree with standard model predictions. The invariant mass distribution of the four-lepton system is used to set limits on anomalous ZZZ and ZZ. couplings at 95% confidence level: -0.0012 < f(4)(Z) < 0.0010, -0.0010 < f(5)(Z) < 0.0013, -0.0012 < f(4)(gamma) < 0.0013, -0.0012 < f(5)(gamma) < 0.0013
