Sparse estimation for case–control studies with multiple disease subtypes
Authors: Ballout Nadim , Garcia Cedric , Viallon Vivian 
Published: December 2019

SummaryThe analysis of case–control studies with several disease subtypes is increasingly common, e.g. in cancer epidemiology. For matched designs, a natural strategy is based on a stratified conditional logistic regression model. Then, to account for the potential homogeneity among disease subtypes, we adapt the ideas of data shared lasso, which has been recently proposed for the estimation of stratified regression models. For unmatched designs, we compare two standard methods based on $L_1$-norm penalized multinomial logistic regression. We describe formal connections between these two approaches, from which practical guidance can be derived. We show that one of these approaches, which is based on a symmetric formulation of the multinomial logistic regression model, actually reduces to a data shared lasso version of the other. Consequently, the relative performance of the two approaches critically depends on the level of homogeneity that exists among disease subtypes: more precisely, when homogeneity is moderate to high, the non-symmetric formulation with controls as the reference is not recommended. Empirical results obtained from synthetic data are presented, which confirm the benefit of properly accounting for potential homogeneity under both matched and unmatched designs, in terms of estimation and prediction accuracy, variable selection and identification of heterogeneities. We also present preliminary results from the analysis of a case–control study nested within the EPIC (European Prospective Investigation into Cancer and nutrition) cohort, where the objective is to identify metabolites associated with the occurrence of subtypes of breast cancer.

Published: December 2019

Abstract
A sensitive, rapid and cost-effective method based on HPTLC with UV detection was developed for the quantitation of Glibenclamide (GLIBEN), Rosiglitazone maleate (ROSI) and Metformin hydrochloride (MET) from a combined dosage form. Pre-coated RP-18 F254s aluminum sheets were used as the stationary phase. Methanol–tetrahydrofuran–water–glacial acetic acid (16: 3.6: 4: 0.4, v/v) used as the mobile phase, along with chamber saturation of 10 min offered an optimum migration (Rf = 0.54, 0.62 and 0.80 for GLIBEN, ROSI and MET, respectively). TLC Scanner 3 was used for densitometric evaluation of the chromatograms. DigiStore 2 Documentation System with winCATS software version 1.4.10 was used for the quantitation and photodocumentation. The LOD for GLIBEN, ROSI and MET was found to be 80 ng, 80 ng and 48 ng, respectively. Moreover, the LOQ was 200 ng, 200 ng and 120 ng for GLIBEN, ROSI and MET, respectively. The method was linear for GLIBEN (r = 0.9991), ROSI (r = 0.9993) and MET (r = 0.9988) within the tested range (200–1000, 200–1000 and 120–600 ng/band, respectively). The method was found to be precise and accurate for all the three drugs. The method was applied for the analysis of Triglucored tablets, and it proved to be a reliable quality control tool for the routine analysis of GLIBEN, ROSI and MET in a combined dosage form.
Stonewall and its Legacy in Iberia
Authors: Cleminson Richard 
Published: December 2019

Abstract
This short article evaluates the changing and conflictive discourse and practice around homosexuality over the twentieth century in Spain and Portugal. The Iberian states were under dictatorship at the time of the Stonewall riots in 1969. Despite the repressive legislation introduced in both countries, it is possible to discern resistance against the law and against a general climate of social opprobrium. Rather than seeing Stonewall as a starting point or an obligatory definitive reference for ‘gay liberation’, the experience of LGBT people in Iberia allows us re-evaluate the history of sexuality against the backdrop of authoritarian regimes, the colonial past and acts of resistance, however small, for a critical history of LGBT life in Europe and beyond.
The survival of business takeovers and new venture start-ups
Authors: Xi Guoqian , Block Jörn , Lasch Frank , Robert Frank , Thurik Roy 
Published: December 2019

AbstractBusiness takeovers and new venture start-ups are two important and distinct entry modes of entrepreneurship. They differ from resource-based and organizational ecology perspectives. We compare firm survival patterns and determinants associated with the two entry modes. From two large French datasets, we find that business takeovers have a higher survival rate than new venture start-ups. However, these differences in survival probability reduce over the entrepreneurship life cycle and when controlling for different entrepreneur and firm characteristics. Moreover, we identify differences in determinants of survival for the two groups, highlighting a distinction between the two entrepreneurship entry modes. This work contributes to the literature on the relationship between entrepreneurship entry and firm survival, thereby contributing to both entrepreneurship and firm survival research.
A “Pedagogy of Discomfort”? Experiential Learning and Conflict Analysis in Israel-Palestine
Authors: Head Naomi 
Published: December 2019

AbstractA “pedagogy of discomfort” (Boler 1999) recognizes the degree to which epistemology, emotions, and ethics are closely entwined both within and beyond our classrooms shaping who, what, where, why, and when we can see. It recognizes not only the intellectual and cognitive focus of education but also its embodied and affective dimensions. A pedagogy of discomfort which engages with the historically, politically, and ideologically contested and the emotionally invested subject of Israel/Palestine offers one way to engage in the teaching and learning of conflict analysis, and to support the development of active and critical student-citizens. This article suggests that experiential learning can support the development of pedagogical discomfort and explores this in the context of the Olive Tree Initiative, a narrative-based and experiential learning program for undergraduate politics and international relations students that focuses on Israel/Palestine. Drawing on student testimony, this article explores the ways in which the program plays a role in challenging dominant social, political, and emotional beliefs in order to create possibilities for individual and social transformation. It also reflects on some of the challenges and limitations posed by this approach, and engages with questions of emotions, vulnerability, and ambiguity in and beyond the classroom.
Native North American ethnography in European collections
Authors: Feest Christian 
Published: December 2019

Abstract
Objects of Native North American origin have entered European collections since the sixteenth century and to this day remain important documents of historical ethnography. Owing to their dispersal to institutions that often lack the expertise required for their proper assessment, and also to the fragmented nature of the available literature in various languages, they have yet to receive the full attention they deserve. The present overview summarizes the results of research and publications on this subject matter since 1992.

Published: December 2019

Abstract
In cystic fibrosis (CF) patients, fungal colonization of the respiratory tract is frequently found. Aspergillus fumigatus is the most frequently recorded and is associated with loss of pulmonary function and allergic disease (ABPA). The knowledge on prevalence rates of filamentous fungi in CF patients in Latin America is scarce. One hundred and seventy-six fungal isolates recovered from the upper respiratory tract of CF patients from Argentina were identified to species by morphology and DNA sequencing. In total, 90% of CF patients were colonized by Aspergillus sp., followed by Exophiala sp. (14%) and Scedosporium sp. (10%). Among Aspergillus, six species complexes (Fumigati, Flavi, Terrei, Nigri, Usti, and Nidulante) and different cryptospecies were found. Among Scedosporium, three species were observed (Scedosporium apiospermum, Scedosporium aurantiacum and Scedosporium boydii). All Exophiala isolates were identified as Exophiala dermatitidis. Rare filamentous fungi were also found. All cases of ABPA were associated to the presence of A. fumigatus. Mixed colonization with other mould or rare fungi was observed in half of them. To our knowledge, this is the first prospective study of mould species in CF using molecular methods in Latin America. This study shows that Aspergillus sp., E. dermatitidis and Scedosporium sp. have a high frequency in CF patients from Argentina, and by far, A. fumigatus was the most commonly cultured species. Continuous clinical surveillance is required to detect the emergence of new fungal pathogens and to detect resistant or difficult-to-treat species capable of chronic colonizing the airways and of hematogenous dissemination in case of lung transplantation.

ABSTRACT
During lunar eclipse of 2019 January 21, a meteoroid impacted the Moon producing a visible light flash. The impact was witnessed by casual observers offering an opportunity to study the phenomenon from multiple geographical locations. We use images and videos collected by observers in seven countries to estimate the location, impact parameters (speed and incoming direction), and energy of the meteoroid. Using parallax, we achieve determining the impact location at lat.$-29.43^{+0.30}_{-0.21}$, lon.$-67.89^{+0.07}_{-0.09}$, and geocentric distance as 356 553 km. After devising and applying a photometric procedure for measuring flash standard magnitudes in multiple RGB images having different exposure times, we found that the flash, had an average G-magnitude 〈G〉 = 6.7 ± 0.3. We use gravitational ray tracing (GRT) to estimate the orbital properties and likely radiant of the impactor. We find that the meteoroid impacted the moon with a speed of $14^{+7}_{-6}$ km s−1 (70 per cent C.L.) and at a shallow angle, θ &lt; 38.2 deg. Assuming a normal error for our estimated flash brightness, educated priors for the luminous efficiency and object density, and using the GRT-computed probability distributions of impact speed and incoming directions, we calculate posterior probability distributions for the kinetic energy (median Kmed = 0.8 kton), body mass (Mmed = 27 kg) and diameter (dmed = 29 cm), and crater size (Dmed = 9 m). If our assumptions are correct, the crater left by the impact could be detectable by prospecting lunar probes. These results arose from a timely collaboration between professional and amateur astronomers that highlight the potential importance of citizen science in astronomy.
Decoupling the rotation of stars and gas – I. The relationship with morphology and halo spin
Authors: Duckworth Christopher , Tojeiro Rita , Kraljic Katarina 
Published: December 2019

ABSTRACT
We use a combination of data from the MaNGA survey and MaNGA-like observations in IllustrisTNG100 to determine the prevalence of misalignment between the rotational axes of stars and gas. This census paper outlines the typical characteristics of misaligned galaxies in both observations and simulations to determine their fundamental relationship with morphology and angular momentum. We present a sample of ∼4500 galaxies from MaNGA with kinematic classifications which we use to demonstrate that the prevalence of misalignment is strongly dependent on morphology. The misaligned fraction sharply increases going to earlier morphologies (28 ± 3 per cent of 301 early-type galaxies, 10 ± 1 per cent of 677 lenticulars, and 5.4 ± 0.6 per cent of 1634 pure late-type galaxies). For early-types, aligned galaxies are less massive than the misaligned sample whereas this trend reverses for lenticulars and pure late-types. We also find that decoupling depends on group membership for early-types with centrals more likely to be decoupled than satellites. We demonstrate that misaligned galaxies have similar stellar angular momentum to galaxies without gas rotation, much lower than aligned galaxies. Misaligned galaxies also have a lower gas mass than the aligned, indicative that gas loss is a crucial step in decoupling star–gas rotation. Through comparison to a mock MaNGA sample, we find that the strong trends with morphology and angular momentum hold true in IllustrisTNG100. We demonstrate that the lowered angular momentum is, however, not a transient property and that the likelihood of star–gas misalignment at $z$ = 0 is correlated with the spin of the dark matter halo going back to $z$ = 1.
Non-Gaussianity constraints using future radio continuum surveys and the multitracer technique
Authors: Gomes Zahra , Camera Stefano , Jarvis Matt J , Hale Catherine , Fonseca José 
Published: December 2019

ABSTRACT
Tighter constraints on measurements of primordial non-Gaussianity (PNG) will allow the differentiation of inflationary scenarios. The cosmic microwave background bispectrum – the standard method of measuring the local non-Gaussianity – is limited by cosmic variance. Therefore, it is sensible to investigate measurements of non-Gaussianity using the large-scale structure. This can be done by investigating the effects of non-Gaussianity on the power spectrum on large scales. In this study, we forecast the constraints on the local PNG parameter fNL that can be obtained with future radio surveys. We utilize the multitracer method that reduces the effect of cosmic variance and takes advantage of the multiple radio galaxy populations that are differently biased tracers of the same underlying dark matter distribution. Improvements on previous work include the use of observational bias and halo mass estimates, updated simulations, and realistic photometric redshift expectations, thus producing more realistic forecasts. Combinations of Square Kilometre Array simulations and radio observations were used as well as different redshift ranges and redshift bin sizes. It was found that in the most realistic case the 1σ error on fNL falls within the range 4.07–6.58, rivalling the tightest constraints currently available.
The Height of Drop
Authors: Kukkonen Karin 
Published: December 2019

Abstract
The chapter details how probability designs build the perception of coincidence and surprise by creating a ‘height of drop’ before plot events. It investigates more closely the role of the reader. The perception of the probability of a certain prediction is manipulated along a range of textual devices, which are discussed on the example of Jane Austen’s Pemberley scene in Pride and Prejudice. These manipulations of precision (that is, the perceived reliability of prediction errors), it is argued, also contribute to readers’ (illusory) sense of agency and their explorative mental moves. While readers follow the probability design, they are actively configuring the predictions of the narrative, which is related to phenomena like anomalous suspense and the paradox of tragedy.
Intertextual Precision Expectations
Authors: Kukkonen Karin 
Published: December 2019

Abstract
In the chapters that follow, the third-order probability design is developed. The third-order probability design revolves around how expectations about second- and first-order predictions are developed through structural patterns yielded by genre (III.1), textual gaps and shadow stories (III.2), and intertextual references to unfamiliar texts (III.3). The final chapter of the section, then, traces the tension between flexibility and constraint in probability designs.
The Cognitive Work of Form
Authors: Kukkonen Karin 
Published: December 2019

Abstract
The chapter unfolds an alternative to simulation-based accounts of literature’s place in the world. Form, conceptualised as probability designs, it is argued, enables the particularity of literature as a designer environment (see IV.2). The chapter redraws the links between probability designs and the world through a double tilt enabled by the lifting of sensory attenuation in reading (see II.1) and through an enhanced exploration in interoception rather than exteroception. The probability design then enables readers to realise the potential of this double tilt to the full through the thought loops of epistemic active inference and remindings. These deliberations lead to the conclusion that literary form is fundamental to freedom of thought.
Introduction
Authors: Berg Christopher 
Published: December 2019

Abstract
This chapter lays out the scope and intended use of The Classical Guitar Companion. It explores how guitarists and teachers can create unique and distinctive curricula of study for themselves or their students to help them acquire and develop fundamental techniques and foundational knowledge. Included are practice guidelines applicable to each chapter of the book. Because all new learning requires a finely honed foundation of prior knowledge and skill, the introduction presents advice that will help guitarists transform their foundational work into advanced technique and a deeper understanding of the instrument. This work will help guitarists meet the artistic and technical demands of advanced guitar literature. The introduction also explores those best served by the book: those studying the classical guitar (whether novice or advanced); guitarists wishing to fill gaps in their background; new guitar teachers looking for guidance with curricula; and guitarists interested in the rich pedagogical heritage of the instrument.
Learning the Fingerboard
Authors: Berg Christopher 
Published: December 2019

Abstract
“Learning the Fingerboard” presents the means for students to understand the logic of the guitar fingerboard and master its grammar so they will be able to understand more easily and quickly the musical language used by composers. Unlike the piano, which has one location for each note, guitarists can play the same scale, chord, or cadence, in multiple locations. The Segovia scales, however—which are widely used for foundational work—don’t cover large areas of the guitar fingerboard. This section begins with the study of open-position major and minor scales and their associated cadences, major and minor moveable scale forms and related chords, and major and minor long scales, which traverse the length of the fingerboard. Harmony is studied through the working out of triads on each of the four sets of three adjacent strings. The section ends with the first modern edition of cadences in commonly used positions for each key by Franz Bathioli.
Scale Exercises and Studies
Authors: Berg Christopher 
Published: December 2019

Abstract
This section will improve students’ understanding of scale technique by exploring the fingering practices of major 19th-century guitarists—Carulli, Carcassi, Sor, Aguado, Coste, Mertz—including how these practices evolved and their significance when performing music by these composers. Then follow a series of scale pieces in the lower positions suitable for students in their first years of study, followed by scale studies in the upper positions suitable for more advanced students. Pieces from the literature for lute are included to provide music containing scales that is accessible to those starting out. This is followed by advanced upper-position material. The section ends with an exploration of how to develop advanced right-hand fingering practices through the use of three-finger patterns to aid the develop of speed and to solve the problems of fingering nonidiomatic music, such as the more difficult works of J. S. Bach.
Saviors, Tyrants, and the Poetics of Empire
Authors: Brumbaugh Michael 
Published: December 2019

Abstract
This chapter examines ways in which the Hymn to Delos revisits the role of the king as a guard, set out in the first hymn. Here, Kallimachos adds nuance to his earlier characterization by distinguishing between the savior, Apollo, who protects and the tyrant, Hera, who oppresses those who are less powerful. As in the preceding hymns, Kallimachos de-emphasizes aspects of his narrative that could be seen as anti-dynastic, presenting in its place a more whimsical account. Explicitly paralleling the birth, kingship, and universal empire of Apollo and Ptolemy II Philadelphos, Kallimachos effectively replaces Zeus with a new paradigm of ideal kingship. This hymn’s embrace of a pan-Mediterranean stage mirrors, in a way, Philadelphos’ efforts to expand his kingdom into a vast, overseas empire during the first years of his reign. During this period, the honorific title Sōtēr, meaning “Savior,” once again gained currency within diplomatic discourse as a way for independent poleis to laud kings who had saved them from invading Gauls. Not only does Kallimachos incorporate this contemporary dynamic into his hymn, but he also maps the diplomatic traffic in praise onto the reciprocal charis dynamic that traditionally obtains between a hymnist and his honorand.
Uncut Galatians
Authors: Marchal Joseph A. 
Published: December 2019

Abstract
Chapter 3 reconsiders the multiple ways Paul’s letter to the Galatians argues with and about bodies and two practices of genital cutting—circumcision and castration. Though it quotes a baptismal tradition (3:28) prized for its scrambling of several embodied factors (Jew/Gentile, slave/free, male/female), it also violently wishes for, even joking about, those seeking circumcision to be castrated, bringing the eunuch as a lingering point of contrast into the foreground of the letter’s argument. Critical reflections on the meaning of modifying bodies with intersex conditions contrast with such uses of eunuch figures, subverting the persistent scholarly focus on Paul focusing on the circumcised penis, a focus that reinstalls a normative view of “member”-ship in the community. The juxtaposition of intersex advocacy with castrated people in antiquity shifts the significance of embodied differences and bodily modifications for the baptized bodies addressed in Galatians.
Assembled Gentiles
Authors: Marchal Joseph A. 
Published: December 2019

Abstract
Chapter 5 resituates figurations from both Paul’s letter to the Romans and Paul’s first letter to the Corinthians, particularly within the two “clobber” passages more recent users claim condemn homosexuality (in Rom 1:18–32 and 1 Cor 6:9–10). The role of Gentiles in Pauline epistles and interpretations are troubled by the figurations of the barbarian and foreign Other that appear in both of these “bashing” passages, highlighting a larger role for sexual exceptionalism than sexual orientation for understanding these arguments. Pauline repetitions of Roman imperial claims about the sexual aberration and inferiority of barbaric foreigners reflect a recurrent, yet altered significance, particularly given ongoing imperial and colonial tendencies. The unexpected resonances between those people addressed in these passages and named in the conclusion of Romans (16:1–16) and those targeted as especially barbaric or terrorizing today name the racialized stereotypes of monstrous sexuality that frequently accompany empires’ insistence about their own sexual exceptionalism and, then, provide an alternative angle on assembly and the intersecting dynamics that bring contingents together.
