Sondologics: Product Diversion and MAP Violations in Internet Channels
Authors: Coughlan Anne T. 
Published: April 2021

Sondologics, a manufacturer of video, audio, and gaming accessories products, was experiencing pricing and distribution problems in its channels. Numerous retailers were complaining about unfair price competition from unauthorized retailers, i.e., gray marketers, on standalone websites or Amazon's Marketplace, offering discounts of up to 30% off list price.
The company estimated that about 10% of its retail volume in the United States was being generated by unauthorized retailers. Compounding the problem, gray marketers and authorized retailers alike were selling at below-list prices, which violated the Sondologics MAP (minimum advertised pricing) policy.
Sondologics was considering numerous initiatives to address the MAP and gray-market problems, including retaining a third-party service to monitor pricing and distribution in the channel. Students are asked to develop recommendations that would promote sales while protecting the name-brand image and price points of Sondologics' products.
What's in a Family Legacy? Balancing Family Emotions and Business Growth at Luse Holdings
Authors: Ward John L. , Luse Ashley E. 
Published: April 2021

After decades of continuity, Luse Holdings faced a new challenge in 2015. The company needed to pivot in a changing industry context—specifically, Luse had lost a bid to a non-union competitor for the first time—and CEO and fourth-generation member Steve Luse was considering three primary options: (1) continue as is, while also adding non-union services; (2) sell part of the business to reduce family risk; or (3) sell the entire business to fund other family interests. A fourth possible option was a maximization-of-growth alternative.
This decision involved more than business considerations alone. The family's legacy as an industry champion and community philanthropist also required considering all relevant stakeholders, including immediate and extended family, employees, and community. Complicating the situation was the lack of an immediately identifiable successor in the next generation of the Luse family, though several fifth-generation members had completed internships with the business including Steve's daughter Ashley, a recent MBA graduate. Students will step into Steve's shoes as he considers what recommendations to make to the advisory board six months from now. Students can also take the perspective of Ashley, a rising next-generation member: should she join the family business?
Estimation of shear‐wave velocities in unconventional shale reservoirs
Authors: Omovie Sheyore John , Castagna John P. 
Published: April 2021

ABSTRACTAnalysis of compressional and shear‐wave sonic logs in seven organic‐rich shale reservoirs exhibiting a wide range of velocities, total organic content, thermal maturity, fluid compressibility and mineral composition indicates that compressional‐wave velocity is a strong predictor of shear‐wave velocity as is the case for conventional reservoirs. Excluding data with high water saturations, a simple linear relationship is found between the compressional and shear‐wave velocities in shale reservoirs in accordance with laboratory measurements. The relationship can be further refined for prediction purposes by local calibration or with a linear correction for total organic content. Correcting for compositional variation and fluid effects requires more complex treatment. An empirical rock physics model that explicitly incorporates these effects results in high accuracy (0.2% average mean error) in shear‐wave velocity estimation for the entire data set. The model also exhibits good precision with mean absolute error of 2%. This is significantly better than what is achieved by rock physics models that do not explicitly consider fluid properties. These results are obtained without local calibration and without requiring correction for thermal maturity, degree of lithification or the shape or distribution of the solid organic matter. Explicit consideration of mineral composition, fluid substitution effects and amount of solid organic matter was necessary in this formulation to achieve this high average prediction accuracy with near zero bias as well as good precision across all formations and without local calibration. The successful use of Gassmann's equations in this algorithm suggests that errors in shear‐wave velocity prediction in shale reservoirs due to violation of the assumptions underlying these equations are either small or self‐compensating.
A consideration on the interest of a pottery typology adapted to the late Sasanian and early Islamic monastery at al‐Qusur (Kuwait)
Authors: Perrogon Rémi , Bonnéric Julie 
Published: April 2021

AbstractSince 2011, the French–Kuwaiti Archaeological Mission in Failaka has aimed at defining the function and the chronology of al‐Qusur, located in the middle of Failaka Island (Kuwait). The central part of the site appeared to be a monastery, mainly occupied in early Islamic times. The creation of a site‐specific pottery typology adapted to this settlement was one of the main objectives of the team. This typology is still in progress and the present paper will highlight the variety of questions that it can address. Certain pottery types provide new information about the monastery’s foundation, probably at the end of the Sasanian period, and abandonment, maybe during the ninth century AD. Pottery studies are also crucial for a better understanding of the monastery’s economic life and the eating practices of the monks. The question of the local or regional provenance of the pottery provides an insight into the inclusion of Failaka in exchange networks.
Between Gender and Kinship: Mediating Rights and Relations in North Indian NGOs
Authors: Kowalski Julia 
Published: April 2021

ABSTRACT Over the past three decades, transnational women's rights discourse has promoted the category gender as a universal tool to evaluate questions of inequality. Building on fieldwork in Jaipur, India, this article argues that the discursive economy of women's rights renders gender global by framing kinship as a local, harmful element of women's social worlds. Mid‐level staff at women's rights organizations, called “family counselors,” demonstrate the complexities of kinship in women's rights institutions. Counselors work with the constraints and possibilities of north Indian kinship systems to support female clients. Yet globally circulating representations of gender inequality as a problem of “Indian patriarchy” present them with a dilemma. Relying upon kin relations marks their work as inexpert, even as such interdependent relations are crucial to both the families they support and the women's rights institutions they serve. By analogizing kinship with local and backwards and gender with global and progressive, women's rights discourse provokes counselors to reimagine the possibilities of kinship, and then erases their efforts.

Published: April 2021

AbstractLaparoscopic ventral hernia repair with intraperitoneal onlay mesh reinforcement is often performed in clinical practice. We herein describe a patient who developed a Spigelian hernia at the edge of the mesh due to rupture of the muscular layer in the abdominal wall. A 69‐year‐old woman developed a left‐sided abdominal bulge 15 months after laparoscopic ventral hernia repair. CT showed a 33‐mm defect in the abdominal wall at the lateral edge of the left abdominal rectus muscle with an intestinal prolapse through the defect. She was diagnosed with a Spigelian hernia and underwent operation. The hernia orifice was located at the aponeurosis of the transverse abdominal muscle where the thread had been used to fix the mesh through all layers of the abdominal wall. This report details a case of a Spigelian hernia after laparoscopic ventral hernia repair.
Multivariate survival analysis in big data: A divide‐and‐combine approach
Authors: Wang Wei , Lu Shou‐En , Cheng Jerry Q. , Xie Minge , Kostis John B. 
Published: April 2021

AbstractMultivariate failure time data are frequently analyzed using the marginal proportional hazards models and the frailty models. When the sample size is extraordinarily large, using either approach could face computational challenges. In this paper, we focus on the marginal model approach and propose a divide‐and‐combine method to analyze large‐scale multivariate failure time data. Our method is motivated by the Myocardial Infarction Data Acquisition System (MIDAS), a New Jersey statewide database that includes 73,725,160 admissions to nonfederal hospitals and emergency rooms (ERs) from 1995 to 2017. We propose to randomly divide the full data into multiple subsets and propose a weighted method to combine these estimators obtained from individual subsets using three weights. Under mild conditions, we show that the combined estimator is asymptotically equivalent to the estimator obtained from the full data as if the data were analyzed all at once. In addition, to screen out risk factors with weak signals, we propose to perform the regularized estimation on the combined estimator using its combined confidence distribution. Theoretical properties, such as consistency, oracle properties, and asymptotic equivalence between the divide‐and‐combine approach and the full data approach are studied. Performance of the proposed method is investigated using simulation studies. Our method is applied to the MIDAS data to identify risk factors related to multivariate cardiovascular‐related health outcomes.
Determinants of protective behaviours during a nationwide lockdown in the wake of the COVID‐19 pandemic
Authors: Scholz Urte , Freund Alexandra M. 
Published: April 2021

ObjectivesWithout pharmaceutical measures available, endorsement of protective behaviours, such as hygiene behaviours, social distancing, and adherence to recommended behaviours in case of symptoms is of key importance to curb the ongoing COVID‐19 pandemic. Based on an extended version of the protection motivation theory, this study examined the role of perceived risks to oneself and to others, self‐efficacy, response efficacy, and perceived social norms for intentions to and the endorsement of several protective behaviours and alternative behaviours known to be ineffective. Further, it was hypothesised that effects of risk perceptions depended on high levels of self‐efficacy.DesignData were collected by telephone at the beginning of the lockdown in Switzerland with a large sample (N = 1,009) representative of the adult Swiss population.MethodsAll predictors (self‐efficacy, response efficacy, perceived social norms, intentions) but risk perceptions were assessed for hygiene behaviours, social distancing, adherence to recommended behaviours in case of symptoms, and alternative measures known to be ineffective.ResultsAcross all analyses of intentions for and endorsement of protective and alternative behaviours, response efficacy and self‐efficacy emerged as the most important predictors. Social norms were mainly related to intentions, but not to behaviours. The different risk perceptions were rarely and inconsistently related to intentions and behaviours. No consistent pattern of interactions between self‐efficacy and risk perceptions emerged.ConclusionThis study demonstrates that even in the face of a pandemic of an unknown virus, the resources (self‐efficacy, response efficacy) rather than the risk perceptions have the potential to promote protective behaviours.

AbstractObjectiveTo perform a systematic review and meta‐analysis of the performance of different methods for detecting carious lesions in permanent and primary teeth, considering all types of tooth surface.MethodsTwo reviewers searched PubMed, Embase, Scopus and other sources up to November 2020 to identify published and nonpublished studies in English. We focused on three caries detection methods: visual inspection (VI), radiographic (RX) and fluorescence‐based (LF). We included studies investigating at least one of these methods which (a) assessed the accuracy of the method in detecting caries lesions; (b) considered occlusal, proximal or free smooth surfaces in primary or permanent teeth; (c) used a reference standard other than one of the three methods; and (d) reported data on sample size and accuracy. Multilevel analyses, meta‐regressions and comparisons of bivariate summary receiver operating characteristics curves were undertaken.ResultsTwo hundred and forty manuscripts from 14 129 articles initially identified met the inclusion criteria. VI was better than RX on occlusal surfaces at all caries lesion thresholds and proximal surfaces of permanent teeth only at all lesion thresholds in laboratory setting. LF was slightly better than VI for advanced lesions on occlusal surfaces of permanent teeth in the clinical setting and for all lesions on proximal surfaces of permanent teeth in the laboratory setting. Still, LF was worse than VI for advanced occlusal lesions in permanent teeth in the laboratory setting. Although LF showed slightly better performance than VI with advanced lesions, the latter had significantly higher specificity than other methods in all settings.ConclusionVisual caries detection alone is adequate for most patients in daily clinical practice regardless of tooth type or surface.
A truss‐based approach for densest homogeneous subgraph mining in node‐attributed graphs

Published: April 2021

AbstractIn a wide range of graph analysis tasks such as community detection and event detection, densest subgraph mining is important and primitive. With the development of social network, densest subgraph mining not only need to consider the structural data but also the attributes information, which descripts the features of nodes or edges. However, there are few researches on densest subgraph mining with attribute description. In this article, we only focus on the node‐attributed graph. According to the properties of structure and attribute in node‐attributed graphs, we define a novel dense subgraph pattern, called hybridized k‐truss in attribute‐augmented graph. A hybridized k‐truss is a subgraph that consists of structural nodes and attribute nodes, of which there are at least (k − 2) common neighbors between any two connected nodes. We introduce the densest hybridized truss problem, and the densest hybridized truss mapping to a densely connected subgraph with homogenous attributes in the original graph. We propose a densest hybridized truss extraction (DHTE) algorithm for node‐attributed graphs, to automatically find the densest subgraph with high density and homogenous attributes at the same time. Extensive experimental results of 21 real world datasets demonstrate the effectiveness and efficiency of DHTE over state‐of‐the‐art methods, through comparison about structural cohesiveness and attributive homogeneity.
Correlation of echocardiographic probability of pulmonary hypertension with maternal outcomes in pregnant women with elevated right ventricular systolic pressure
Authors: Marshall William H. , Gee Stephen , Lim Woobeen , Rajpal Saurabh 
Published: April 2021

AbstractIntroductionThe use of echocardiography to evaluate the probability for pulmonary hypertension (PH) in pregnant women has not been reported or correlated with outcomes. We hypothesized that in women with elevated right ventricular systolic pressure (RVSP) on echocardiography first identified during pregnancy, those with low probability for PH would have fewer major adverse cardiac events (MACE).MethodsWe performed a retrospective cohort study of pregnant women with RVSP >35 mm Hg on echocardiogram first identified during pregnancy. Women were classified as intermediate‐high probability for PH (HP) or low probability for PH (LP) based on simplified European Society of Cardiology echocardiographic criteria. Maternal cardiac, obstetric, and fetal outcomes were assessed.ResultsA total of 77 women met inclusion criteria (mean age 30 ± 5 years), with 45 (58%) classified as HP and 32 (42%) as LP. There were 21 (27%) women who experienced MACE, more commonly in the HP cohort (HP 18 (40%) women vs. LP 3 (9%) women, P = .01). The echocardiographic criteria for intermediate‐high probability of PH identified women at risk for MACE with 85% sensitivity and 52% specificity. The negative predictive value for MACE in women meeting low echocardiographic probability for PH criteria was 91%.ConclusionsIn women with elevated RVSP on echocardiography first identified during pregnancy, those with low echocardiographic PH probability are at significantly lower risk for MACE during pregnancy, though the risk is not eliminated. This may be useful to risk stratify pregnant women with suspected PH, guiding tertiary care referral and invasive catheterization.

Published: April 2021

AbstractInnate lymphoid cells (ILCs) are classified by the expression of specific transcription factors: ILC1 depending on T‐bet for IFN‐γ production; ILC2 depending on GATA3 for IL‐5 and IL‐13; and ILC3 depending on ROR‐γτ and AHR for IL‐17 and IL‐22. This study aimed to determine circulating ILCs in 23 patients with localized (LCL) = 7, mucocutaneous (MCL) = 10, intermediate (ICL) = 3 and diffuse (DCL) = 3 cutaneous leishmaniasis and 17 healthy controls from endemic area (EC) = 9 and non‐endemic area (HC) = 8. Results evidenced a higher proportion of ILC1 in LCL than controls and MCL. ILC2 was higher in DCL compared with controls. ILC3 s were abundant in MCL and DCL concerning controls. A prevalence ratio was calculated to approach cell plasticity: in LCL, the ratio showed a prevalence of ILC1/ILC3 (plasticity 1), in contrast to DCL, and controls, where ILC2/ILC3 (plasticity 3) is prevalent. Also, MCL and ICL showed higher ILC1/ILC2 (plasticity 2). These results suggest that ILC1 and ILC3 in LCL are associated with disease control and regulation of inflammation, while MCL and ICL are related to immunopathology and uncontrolled inflammation. In DCL, ILC2 is associated with the tolerogenic state of these patients.
ROMANTIC NATIONALISM OR ROMANTIC RETREAT? RE‐EVALUATING THE POLITICS OF ARNIM AND BRENTANO'S DES KNABEN WUNDERHORN (1805/1808)
Authors: Pilsworth Ellen 
Published: April 2021

ABSTRACTThis article argues for a new approach to war and politics in Arnim and Brentano's Romantic poetry anthology Des Knaben Wunderhorn. It departs from previous Wunderhorn scholarship by considering the collection's three volumes individually, and paying attention to the different political circumstances of the two phases of its creation, 1805 and 1808. I show that there is a change of emphasis in the collection between volume I (1805) and volumes II and III (1808), identifying a shift away from political engagement and a withdrawal of the nationalist sentiments that are still, however, often associated with the collection as a whole. Instead, I argue that the later volumes of the collection turn inwards and come to reflect a more spiritual and escapist aspect of Romanticism, with a focus on the figure of the artist rather than any political goal. By exploring the change in emphasis between 1805 and 1808, my reading presents the Wunderhorn as a text torn internally between a tangible engagement with everyday politics on the one hand, and a tendency towards transcendence on the other. In this way, the collection represents two opposing impulses of German Romanticism around 1800. Dieser Artikel erprobt eine neue Herangehensweise an das Thema Krieg und Politik in Arnims und Brentanos romantischer Liedersammlung Des Knaben Wunderhorn. Im Unterschied zu anderen Wunderhorn‐Studien betrachte ich die drei Bände der Sammlung als eigenständige Werke und berücksichtige verstärkt die unterschiedlichen politischen Umstände ihrer Entstehungsphasen 1805 und 1808. Meine These ist, dass innerhalb der Sammlung zwischen Band I (1805) und den Bänden II und III (1808) eine Schwerpunktverlagerung stattfindet. Statt der gängigen Lesart, die politisches Engagement und nationalistischen Überschwang mit der ganzen Sammlung verbindet, konstatiere ich eine wachsende Abkehr vom politischen Denken und ein Erkalten der nationalistischen Gefühle nach 1807. Ich schlage vor, die späteren Bände der Sammlung als Beschäftigung mit anderen Aspekten der Romantik, ihrer Hinwendung zu Innerlichkeit und Geistigkeit zu lesen. Der Schwerpunkt vieler Gedichte liegt daher mehr auf der Figur des Künstlers als auf einem politischen Ziel. Meine Untersuchung dieser Verschiebung zwischen 1805 und 1808 zeigt, dass das Wunderhorn ein Text ist, der zwischen der konkreten Auseinandersetzung mit der Alltagspolitik und einem transzendentalen Streben hin‐ und hergerissen ist. Auf diese Weise vereint die Sammlung zwei gegensätzliche Impulse der deutschen Romantik um 1800.
BETWEEN ‘URBILD’ AND ‘ABBILD’: THE CONCEPTION OF THE IMAGE IN CELAN'S POEMS ‘BEI WEIN UND VERLORENHEIT’, ‘TENEBRAE’, AND ‘HALBZERFRESSENER’
Authors: Koch Julian Johannes Immanuel 
Published: April 2021

ABSTRACTThis article contends that the image is a central trope in Paul Celan's poetry. It suggests that Celan's rejection of metaphor and his opposition to readings of his poetry as mere imagery constitute only one side of his understanding of the image. On the other hand, Celan embraces the image when it goes beyond the merely figurative or imitative and approaches a form of ‘Urbild’. This article traces Celan's understanding of the image as split between ‘Urbild’ and ‘Abbild’ in his mature poems ‘Bei Wein und Verlorenheit’, ‘Tenebrae’, and ‘Halbzerfressener’, through which we will also gain a fuller sense of how Celan conceives of language and poetic voice.
Improving Risk‐Based Screening at Vapor Intrusion Sites in California
Authors: Lahvis Matthew A. , Ettinger Robert A. 
Published: April 2021

AbstractThe attenuation factor (AF) of 0.03 recommended by the U.S. Environmental Protection Agency (USEPA) is increasingly being used by regulatory agencies for the development of subsurface vapor screening levels for vapor intrusion (VI). There are concerns, however, over the database used to derive the AF and the AF's applicability to building types and geographies not included in USEPA database. To derive a more technically defensible AF for subsurface vapor screening in California, a database consisting of 8415 paired indoor and subsurface vapor samples collected from 485 buildings at 36 sites in California was compiled. Filtering was applied to remove data of suspect quality that were potentially affected by background (non‐VI) sources. Filtering reduced the size of the database to 788 indoor air and subsurface vapor pairs, 80% of which were trichloroethylene (TCE) measurements. An AF of 0.0008 was derived from only TCE vapor data, based on the ability of the AF to reliably identify buildings with indoor air concentrations above screening levels in 95% of cases where subsurface vapor screening levels were exceeded. The AF derived from this study demonstrated limited sensitivity to the variables typically considered important in VI characterization, which was partially attributed to relatively weak correlation of indoor air and subsurface vapor concentration data. The results of this study can be used to improve VI screening in California and other states and help focus limited resources on sites posing the greatest potential risk.
