A self-adjoint velocity-stress full-waveform inversion approach to microseismic source estimation
Authors: Kaderli Jordan , McChesney Matthew D. , Minkoff Susan E. 
Published: June 2018

Accurate estimation of microseismic events in time and space enables important characterization of hydraulic fracture networks. Determining the orientation of the fracture can help differentiate between reactivation of an in situ fracture and a hydraulically induced fracture, which is important in characterizing the effectiveness of the stimulation process. We consider the source as separable in time and space and invert for a complete description of the source in one of these two dimensions assuming the other is known. We recover the wavelet, which includes the source amplitude and time evolution. In space, we recover a description of the source that is distributed and includes an estimate of the moment tensor at every point in the domain. A change of variables applied to the velocity-stress form of the elastic-wave equation ensures that the system is self-adjoint. Thus, full-waveform inversion can be tailored to estimate microseismic events with limited modifications to the forward wave solver. The inversion does not use any a priori assumptions about the form of the source, does not require a good starting guess for accurate source recovery, and is robust in the presence of noise. Applying this technique to wavelet inversion correctly recovers a 30 Hz Ricker wavelet from a zero initial guess with and without noise. Furthermore, for a realistic microseismic event generated from coupled flow and deformation modeling, the algorithm recovers the peak time and approximate shape of the wavelet. In fact, our algorithm recovers as much of the true wavelet as possible given the energy in the observed data. Furthermore, experiments involving a distributed source in the shape of an ellipse illustrate that the inversion scheme can not only estimate the focal mechanism of failure events, but also the geometry of the failure plane.
A practical implementation of subsalt Marchenko imaging with a Gulf of Mexico data set
Authors: Jia Xueyi , Guitton Antoine , Snieder Roel 
Published: June 2018

Marchenko redatuming allows one to use surface seismic reflection data to generate the seismic response from sources at the surface to any point in the subsurface. Without requiring much information about the earth’s properties, the seismic response generated by Marchenko redatuming contains accurate estimates of not only the primaries but also the internal multiples. A target-oriented imaging method, referred to as Marchenko imaging, was implemented for imaging complex structures of the earth using the seismic response obtained through Marchenko redatuming. Taking account of the contribution of primaries and internal multiples, Marchenko imaging produces images that contain fewer artifacts than the images obtained using conventional imaging methods (e.g., reverse time migration) with the same input data. In this study, we applied Marchenko imaging to a field data set acquired at the Gulf of Mexico to produce an image of a subsalt area. We investigated two important and practical aspects of the Marchenko framework: (1) the missing near offsets in marine shot records and (2) the calibration of the reflection data. Finally, we suggested a workflow for processing the marine towed-streamer field data set acquired at the Gulf of Mexico, and we have developed a complete theoretical and practical framework to produce a target-oriented subsalt image using the Marchenko methods. The images obtained from Marchenko imaging are consistent and comparable, for the most part, with conventional migration methods. However, Marchenko imaging achieves improvements in the continuity of the geologic structures and in suppressing the artifacts that are caused by internal multiples.
From World to Globe: The Transformation of Israeli Cultural Production in the Time of Neoliberal Globalization
Authors: Cohen Kfir 
Published: June 2018

Abstract
This essay examines recent developments in Israeli cultural production. To do so, it argues, we must think of new cultural forms as responses to the neoliberal privatization reforms that accompany globalization. These reforms have altered Israeli social life to the degree that the once peripheral literature and cinema that conformed to Fredric Jameson's definition of Third World national allegories can now be read as symptoms of First World cultural production. This historical and aesthetic shift has made itself felt at the heart of Israeli daily life in the rearticulation of the relation between private and public spheres. Recent Israeli literature and film consequently invite us to rethink the stylistic preoccupation of contemporary theories of world literature by asking how these media use aesthetic figures to give form to the concepts of freedom, necessity, and knowledge. To look at this aesthetic and political shift, I offer a comparative reading of Yeshayahu Koren's 1967 novella, Funeral at Noon, and Adam Sanderson's 2014 cinematic adaptation of that novella.
Romancing the Anthropocene: H. G. Wells and the Genre of the Future
Authors: Rosenberg Aaron 
Published: June 2018

Abstract
This essay considers how the representation of deep time affects, and is affected by, literary genres. It takes The Time Machine (1895) as its case study, investigating the ways in which H. G. Wells's work repurposes the conventions of the romance genre as a means of narrating expansive temporal scales that exceed the representational capacity of the realist novel. The essay's overarching suggestion is that stretching narratives to the extreme longue durée of the geologic epoch necessitates shifting away from realism, opening new possibilities for genres (including melodrama, epic, and, in this case, romance) that the realist tradition had ostensibly superseded. Understanding how the formal expansiveness of literary genres can be mobilized strategically, it concludes, affords a critical perspective for analyzing the Anthropocene—a concept whose narrative and discursive patterns concern the contemporaneity of deep time and the present and that could itself be construed as a genre.
A Tale of Two Materialisms
Authors: Hoyos Héctor 
Published: June 2018

AbstractNew materialist approaches to the novel call into question the hermeneutical value of suspicion and critique. Meanwhile, historical materialism tends to neglect aspects of form, focusing instead on social function. Drawing from Las comidas profundas (1997), by Cuban writer Antonio José Ponte, and Cuban Counterpoint: Tobacco and Sugar (1940, trans. 1995), by anthropologist Fernando Ortiz, the essay charts a third approach, transcultural materialism, that reconciles the two tendencies. Works written in this mode deploy narrative and literary language to articulate labor with nonhuman themes, demonstrating the continuity of phenomena across botanical, economic, and cultural realms. Crucially, literature here serves as the primary means for critical elucidation rather than as the mere illustration of political ecological ideas. The limit case considered in the article—stories from the island of Cuba and its staples of tobacco, sugar, and scarce food—allows for a reconsideration of the role of objects in fiction both as stand-ins for social relations and as agents in their own right. In closing, the essay outlines three principles for a world literature infused with transcultural materialism: contemporaneity, multipolarity, and hospitality.
Modeling Consumer Footprints on Search Engines: An Interplay with Social Media
Authors: Ghose Anindya , Ipeirotis Panagiotis G. , Li Beibei 
Published: June 2018

It is now well understood that social media plays an increasingly important role in consumers’ decision making. However, an overload of social media content in product search engines can hinder consumers from efficiently seeking information. We propose a structural econometric model to understand consumers’ preferences and costs on search engines to improve user experience under unstructured social media. Our model combines an optimal stopping framework with an individual-level random utility choice model and analyzes click behavior in conjunction with purchase choices. Our model accounts for three major constraints in a consumer’s decision-making process: (1) interdependency in decision making for different alternatives, (2) sequential arrival of information revealed by click-throughs, and (3) nonnegligible search cost. Our approach allows us to jointly estimate consumers’ heterogeneous preferences and search costs under the interplay of social media and search engines, and to predict search and purchase behavior for each consumer. We validate the model using an individual session-level data set of approximately seven million observations resulting in room bookings in 2,117 U.S. hotels. Interestingly, our analysis allows us to quantify the trade-off between consumers’ benefits and cognitive costs from using large-scale unstructured social media information during decision making. Our policy experiments show that providing a carefully curated digest of social media content during the earlier stages of consumer search (i.e., on the search results summary page) can lead to a 12.01% increase in the overall search engine revenue.

Losing Common Ground: Social Sorting and Polarization
Authors: Mason Lilliana 
Published: June 2018

AbstractThe alignment between partisan and other social identities has generated a rift between Democrats and Republicans that is deeper than any seen in recent American history. Without the cross-cutting identities that have traditionally stabilized the American two-party system, partisans in the American electorate are now seeing each other through prejudiced and intolerant eyes. In this article, partisan social divisions are examined in the 2016 electorate, with an eye to the co-occurrence between these social divisions and contemporaneous resistance to compromise and intolerance of social outgroups. In particular, as Republicans and Democrats grow more socially distinct, they like outgroups less and privilege victory over the national greater good. This effect is particularly visible among Republicans, whose social makeup is particularly homogeneous, even in comparison with Democrats. Some potential solutions are briefly addressed.
Affective Polarization and Ideological Sorting: A Reciprocal, Albeit Weak, Relationship
Authors: Lelkes Yphtach 
Published: June 2018

AbstractAmerican partisans are far more hostile towards out-party members than they were 40 years ago. While this phenomenon, often called affective polarization, is well-documented, political scientists disagree on its cause. One group of scholars believes that affective polarization is driven by processes related to social identity theory. In particular, cross-cutting identities have declined in America, and toxic political communication continuously primes partisan identities and resentment. Recently, several scholars have pointed to another phenomenon as the root cause of affective polarization: partisan sorting, i.e. the alignment of partisan identities with ideologically consistent issue positions. I review evidence in favor of each claim, and provide additional evidence that affective polarization has increased about as much among those who are not sorted as among those who are sorted. Furthermore, while sorting is only related to affective polarization among the most politically knowledgeable, affective polarization has increased across all levels of political knowledge. Finally, affective polarization may also increase sorting, further complicating any clear cut causal relationship.

AbstractThe occurrence of microfossil assemblage represented by calpionellids in close association with benthic foraminifera and encrustingCrescentiella morronensisis reported for the first time from the Upper Tithonian of NE Serbia. The biostratigraphic and sedimentological investigations were carried out on a 250 m thick carbonate succession in Jelenska Stena quarry cropping out along the Danube River Gorge in the border area of Serbian Carpatho–Balkanides and Romanian Southern Carphatians. On the basis of determined benthic foraminiferal taxaTextulariasp. cf.T. bettenstaedtiandEverticyclammina praekelleriin the lower part of the succession and calpionellid association dominated by the representatives of calpionellid generaTintinnopsella, CrassicollariaandCalpionellathe carbonate succession is assigned to the Upper Tithonian. The scarcity of calpionellid zonal species prevents the nominal zones being recognized. Petrographic analysis of thin-sections led to the recognition of three basin microfacies types: bioclastic wackestone, bioclastic peloidal wackestone/packstone and mudstone. These microfacies characterize the SMF 3 and SMF 4 which indicate deposition in slope and toe-of-slope environments. This study extends the palaeogeographical distribution of Upper Tithonian calpionellids along the northern Tethyan margins. The investigated carbonate succession is compared with coeval strata from other northern Tethyan regions.
Overview of tissue kallikrein and kallikrein-related peptidases in breast cancer
Authors: Figueroa Carlos D. , Molina Luis , Bhoola Kanti D. , Ehrenfeld Pamela 
Published: June 2018

Abstract
The kallikrein family comprises tissue kallikrein and 14 kallikrein-related peptidases (KLKs) recognized as a subgroup of secreted trypsin- or chymotrypsin-like serine proteases. KLKs are expressed in many cellular types where they regulate important physiological activities such as semen liquefaction, immune response, neural development, blood pressure, skin desquamation and tooth enamel formation. Tissue kallikrein, the oldest member and kinin-releasing enzyme, and KLK3/PSA, a tumor biomarker for prostate cancer are the most prominent components of the family. Additionally, other KLKs have shown an abnormal expression in neoplasia, particularly in breast cancer. Thus, increased levels of some KLKs may increase extracellular matrix degradation, invasion and metastasis; other KLKs modulate cell growth, survival and angiogenesis. On the contrary, KLKs can also inhibit angiogenesis and produce tumor suppression. However, there is a lack of knowledge on how KLKs are regulated in tumor microenvironment by molecules present at the site, namely cytokines, inflammatory mediators and growth factors. Little is known about the signaling pathways that control expression/secretion of KLKs in breast cancer, and further how activation of PAR receptors may contribute to functional activity in neoplasia. A better understanding of these molecular events will allow us to consider KLKs as relevant therapeutic targets for breast cancer.

Populism Is a Distraction
Authors: Nederveen Pieterse Jan 
Published: June 2018

Abstract
Should a discussion of populism be concerned with populism—along with revulsion of its various extremisms (perhaps along with hints of social and psychopathology and hence, implicit endorsement of ‘moderate’ positions)? Or should it rather be concerned with the failure of institutions and the misbehavior of elites in a world in which 8 billionaires own as much as half the world population? Option a) will yield a totally different and probably somewhat more predictable discussion than option b), which may include ‘from bad to worse’. According to option c) different types of populism—including ‘pluto-populism’—should generate different treatments. This discussion follows options b) and c).

Utilization of prevention and health promotion among migrants
Authors: Spallek Jacob , Schumann Maria , Zeeb Hajo 
Published: June 2018

Abstract
The uptake of existing preventive and health promotion offers by migrants in Germany is rather heterogeneous, and major information gaps are noted. Current results provide limited evidence that migrants and their children seem to use prevention and health promotion services less frequently than non-migrants. In order to improve access to preventive and other health services for migrants, a combination of migrant-specific and migrant-sensitive approaches seems to be useful.
On the energy dissipative spatial discretization of the barotropic quasi-gasdynamic and compressible Navier–Stokes equations in polar coordinates
Authors: Zlotnik Alexander 
Published: June 2018

Abstract
The barotropic quasi-gasdynamic system of equations in polar coordinates is treated. It can be considered a kinetically motivated parabolic regularization of the compressible Navier–Stokes system involving additional 2nd order terms with a regularizing parameter τ > 0. A potential body force is taken into account. The energy equality is proved ensuring that the total energy is non-increasing in time. This is the crucial physical property. The main result is the construction of symmetric spatial discretization on a non-uniform mesh in a ring such that the property is preserved. The unknown density and velocity are defined on the same mesh whereas the mass flux and the viscous stress tensor are defined on the staggered meshes. Additional difficulties in comparison with the Cartesian coordinates are overcome, and a number of novel elements are implemented to this end, in particular, a self-adjoint and positive definite discretization for the Navier–Stokes viscous stress, special discretizations of the pressure gradient and regularizing terms using enthalpy, non-standard mesh averages for various products of functions, etc. The discretization is also well-balanced.
The main results are valid for τ = 0 as well, i.e., for the barotropic compressible Navier–Stokes system.

BACKGROUND:Evidence on the relationship between maternal depression and exposure to intimate partner violence (IPV) with child physical growth and development is equivocal. Our aim in the current study is to examine these relationships among women and their children in Tanzania.METHODS:The Bayley Scales of Infant Development and anthropometric measures were used to assess children 18 to 36 months of age (n = 1031). Maternal exposure to IPV and depression were assessed using the Tanzania Demographic and Health Survey questionnaire and the Patient Health Questionnaire-9, respectively. We used linear regression models to calculate standardized mean differences (SMDs) for developmental outcomes and generalized linear models to estimate the associations with nutritional status.RESULTS:Mild depressive symptoms in mothers (Patient Health Questionnaire-9 ≥5) and exposure to physical and sexual IPV were associated with lower SMDs for motor skills (−0.14 [P = .023] and −0.23 [P &lt; .01], respectively), expressive communication (−0.13 [P = .187] and −0.23 [P &lt; .01], respectively), receptive communication (−0.19 [P &lt; .009] and −0.16 [P = .03], respectively), and cognitive development (−0.08 [P = .245] and −0.12 [P = .07], respectively). Exposure to physical and sexual IPV was associated with higher risk for stunting (relative risk = 1.6; P &lt; .001).CONCLUSIONS:This study reveals that maternal depressive symptoms and IPV are associated with adverse child nutritional and developmental outcomes. Further research is needed to develop programs to address IPV and depression among women and enhance the growth and development of their children.

Published: June 2018

OBJECTIVES:Incidental isolated mild to moderate thrombocytopenia is a frequent laboratory finding prompting a referral to pediatric hematology-oncology. We tested the hypothesis that patients with isolated asymptomatic mild thrombocytopenia would not progress to require an intervention from a pediatric hematologist–oncologist.METHODS:This is a 5-year retrospective review of 113 patients referred to pediatric hematology–oncology for isolated thrombocytopenia. Initial, lowest, and current platelet counts along with clinical course and need for interventions were recorded. Thrombocytopenia was categorized as mild (platelet count: 101–140 × 103/μL), moderate (platelet count: 51–100 × 103/μL), severe (platelet count: 21–50 × 103/μL), and very severe (platelet count: ≤20 × 103/μL).RESULTS:Eight of 48 patients (17%) referred for initial mild isolated thrombocytopenia progressed to moderate thrombocytopenia at 1 visit. At present, 2 of these patients have moderate thrombocytopenia, 17 remain with mild thrombocytopenia, and 29 patients have resolved thrombocytopenia. Nine of 65 patients (14%) referred for moderate thrombocytopenia progressed to severe or very severe thrombocytopenia on 1 occasion. At present, no patients have severe thrombocytopenia, 18 remain with moderate thrombocytopenia, 14 improved to mild thrombocytopenia, and 33 have resolved thrombocytopenia. Only 3 patients required interventions from a hematologist, whereas 10 patients required therapy from other subspecialties.CONCLUSIONS:We only identified 3 patients (3%) with mild to moderate thrombocytopenia who required an intervention from a hematologist to improve platelet counts. Patients with isolated mild thrombocytopenia with a normal bleeding history and physical examination findings frequently have normalized their platelet counts within 1 month.
