Professional Learning With Preservice Teachers: The IRA Student Council at Clemson University
Authors: McNair Jonda C. , Aker Lisa D. 
Published: February 2020

AbstractWhile highlighting an undergraduate student council at a university, the authors emphasize the importance of being involved in professional organizations. First, the authors briefly highlight scholarship related to professional learning, then give examples of ways that undergraduates were involved in professional learning and community service through their student council. The authors conclude with logistical information and pitfalls related to sustaining the student council, as well as recommendations for others who may be interested in starting councils in their communities. Although the focus of this teaching tip is on working with preservice teachers in a student council located on a college campus, the ideas and suggestions are also applicable for those who want to create local councils for inservice teachers.
Lightning predator: the Ferruginous Pygmy Owl snatches flower-visiting hummingbirds in southwestern Brazil
Authors: Sazima Ivan 
Published: February 2020

Abstract
Pygmy owls of the genus Glaucidium prey on large insect and small vertebrates, mostly birds. Among the birds preyed on by pygmy owls are hummingbirds, caught mostly while mobbing these owlets or when still at nestling stage. I report here on the Ferruginous Pygmy Owl (Glaucidium brasilianum) snatching flower-visiting hummingbirds in an orchard at a farm in southwestern Brazil. I recorded one White-tailed Goldenthroat (Polytmus guainumbi) and three Gilded Hummingbirds (Hylocharis chrysura) preyed on by this owlet on three consecutive days. The large concentration of flowers and, consequently, of hummingbirds in the orchard likely contributed to the hunting success of the owlet on such fleeting and quickly moving prey. The role this pygmy owl plays on predation of adult hummingbirds in the Neotropics merits closer consideration.
Aggregations of Southern Caracaras (Caracara plancus) in soybean plantations in central Cerrado, Brazil
Authors: Tubelis Dárius Pukenis 
Published: February 2020

AbstractThis study reports on large aggregations of Southern Caracaras (Caracara plancus) in soybean plantations in the surroundings of Parque Nacional das Emas, southwestern Brazil. Observations were done during harvesting activities in February 2009. Aggregations were found by driving a vehicle through roads that crossed or bordered soybean plantations located at less than 4 km from this park. For each aggregation detected, individuals found around harvesting machines were counted. The abundance of Southern Caracaras of each aggregation ranged between 76 and 104 individuals (n = 8). Despite the attraction of high numbers of caracaras to proximities of machines, most of them appear to do not obtain much food resources during harvesting of soybean fields. Caracaras were seen capturing small mammals, lizards, birds and large insects. This association between C. plancus and harvesting activities can be considered as opportunist behavior in response to rapid modification of grain-production landscapes in the Cerrado.
A case of beak deformity in the Shiny Cowbird Molothrus bonariensis and a review on beak deformities in wild birds in Brazil
Authors: Purificação Keila Nunes 
Published: February 2020

AbstractBeak deformities in wild birds are rarely reported. Here, I described a case of beak deformity in Shiny Cowbird,Molothrus bonariensis, and also provide a review on beak deformities recorded in wild birds in Brazil. In October 2016, I observed aM. bonariensiswith a grossly elongated maxilla in the east region of the Mato Grosso state, Brazil. The literature review revealed 60 records of beak deformities in the Brazilian avifauna. The most common types of deformity were crossed maxillae or mandibles (38%), probable accidental injuries (27%), and elongations (15%). Deformities were reported in 35 bird species of 22 families. The most affected species wasRamphastos tocowith 21 records. The number of published reports from Brazil was low overall, and are not related as an epizootic episode recorded in some bird communities.
Semipalmated Sandpiper Calidris pusilla in Brazil: occurrence away from the coast and a new record for the central-west region
Authors: de Lima Pereira Karla Dayane , de Oliveira Jayrson Araújo 
Published: February 2020

AbstractThe Semipalmated Sandpiper, Calidris pusilla, is a Western Hemisphere migrant shorebird for which Brazil forms an internationally important contranuptial area. In Brazil, the species main contranuptial areas is along the Atlantic Ocean coast, in the north and northeast regions. In addition to these primary contranuptial areas, there are also records of vagrants widely distributed across Brazil. Here, we review the occurrence of vagrants of this species in Brazil, and document a new record of C. pusilla for the central-west region and a first occurrence for the state of Goiás.

Published: February 2020

AbstractThe advent of immunotherapy has revolutionized how we manage and treat cancer. While the majority of immunotherapy-related studies performed to date have focused on adult malignancies, a handful of these therapies have also recently found success within the pediatric space. In this review, we examine the immunotherapeutic agents that have achieved the approval of the US Food and Drug Administration for treating childhood cancers, highlighting their development, mechanisms of action, and the lessons learned from the seminal clinical trials that ultimately led to their approval. We also shine a spotlight on several emerging immunotherapeutic modalities that we believe are poised to have a positive impact on the treatment of pediatric malignancies in the near future.

Published: February 2020

AbstractAbiotic and biotic properties of soil can influence growth and chemical composition of plants. Although it is well-known that soil microbial composition can vary greatly spatially, how this variation affects plant chemical composition is poorly understood. We grew genetically identicalJacobaea vulgarisin sterilized soil inoculated with live soil collected from four natural grasslands and in 100% sterilized soil. Within each grassland we sampled eight plots, totalling 32 different inocula. Two samples per plot were collected, leading to three levels of spatial variation: within plot, between and within grasslands. The leaf metabolome was analysed with1H Nuclear magnetic resonance spectroscopy (NMR) to investigate if inoculation altered the metabolome of plants and how this varied between and within grasslands. Inoculation led to changes in metabolomics profiles ofJ. vulgarisin two out of four sites. Plants grown in sterilized and inoculated soils differed in concentrations of malic acid, tyrosine, trehalose and two pyrrolizidine alkaloids (PA). Metabolomes of plants grown in inoculated soils from different sites varied in glucose, malic acid, trehalose, tyrosine and in one PA. The metabolome of plants grown in soils with inocula from the same site was more similar than with inocula from distant sites. We show that soil influences leaf metabolomes. Performance of aboveground insects often depends on chemical composition of plants. Hence our results imply that soil microbial communities, via affecting aboveground plant metabolomes, can impact aboveground plant-insect food chains but that it is difficult to make general predictions due to spatial variation in soil microbiomes.

AbstractA new Ba2CuO4-y superconductor with critical temperature (Tc) exceeding 70 K was discovered. The X-ray absorption measurement gives evidence that this cuprate resembles La2CuO4 but is doped with a fairly large amount of holes, while in contrast to the so far known hole-doped high-Tc cuprates, the new cuprate possesses a much shorter local apical oxygen distance as well as much expanded in-plane Cu–O bond, leading to unprecedented compressed local octahedron. In compressed local octahedron, the Cu3d3z2–r2 orbital level will be lifted above the Cu3dx2-y2 orbital level with more three-dimensional features, implying that pairing symmetry may carry admixtures from more than one gap, suggesting that Ba2CuO4-y composed of alkaline earth copper oxides that are the essential elements to form cuprate superconductors may belong to a new branch of cuprate superconductors.
Market Fashioning
Authors: Aspers Patrik , Bengtsson Petter , Dobeson Alexander 
Published: February 2020

AbstractHow do markets come about? This article offers a first systematic analysis of three different ideal types of market fashioning: mutual adjustment, organization, and fields. Although aspects of these are identifiable in most empirical markets, these three ideal types provide analytic tools for students of real markets and marketplaces. After going through this comprehensive literature, it is argued that mutual adjustment, which refers to non-planned processes, is affinity with markets in which products are differentiated, for example, producer markets. Organization refers to process driven by attempts to decide for others and shows affinity with markets for standardized and homogenous products, for example, stock exchanges. Organization also accounts for the making of marketplaces. The broader notion of fields does not refer to any specific process, but accounts for the context of market fashioning and its respective power struggles.

Abstract
Purpose of Review
Cancer diagnosis in young pregnant women challenges oncological decision-making. The International Network on Cancer, Infertility and Pregnancy (INCIP) aims to build on clinical recommendations based on worldwide collaborative research.

Recent Findings
A pregnancy may complicate diagnostic and therapeutic oncological options, as the unborn child must be protected from potentially hazardous exposures. Pregnant patients should as much as possible be treated as non-pregnant patients, in order to preserve maternal prognosis. Some approaches need adaptations when compared with standard treatment for fetal reasons. Depending on the gestational age, surgery, radiotherapy, and chemotherapy are possible during pregnancy. A multidisciplinary approach is the best guarantee for experience-driven decisions. A setting with a high-risk obstetrical unit is strongly advised to safeguard fetal growth and health. Research wise, the INCIP invests in clinical follow-up of children, as cardiac function, neurodevelopment, cancer occurrence, and fertility theoretically may be affected. Furthermore, parental psychological coping strategies, (epi)genetic alterations, and pathophysiological placental changes secondary to cancer (treatment) are topics of ongoing research.

Summary
Further international research is needed to provide patients diagnosed with cancer during pregnancy with the best individualized management plan to optimize obstetrical and oncological care.
AML—is it time to drive a CAR(-T)?
Authors: Rudzki Jakob D. , Wolf Dominik 
Published: February 2020

SummaryThe treatment options for newly diagnosed and relapsed/refractory acute myeloid leukemia (AML) have substantially improved over the last 5 years. However, even though novel targeted agents (e.g. venetoclax, IDH1/2 and novel FLT-3 inhibitors; cytosolic isocitrate dehydrogenase 1/2 and fms-like tyrosine kinase 3 inhibitor) and improved chemotherapeutics (e.g. CPX-351; liposomale Daunorubicin/Cytarabine) are entering clinics, physicians are still confronted with high relapse and treatment failure rates. Thus, novel new strategies are required to improve AML therapy. Application of genetically engineered T cells (i.e. chimeric antigen receptor T cells, CAR-T cells) has proven to be highly effective in B cell-derived neoplasia and early data suggest also a high potential in the treatment of AML. This short review highlights the current approaches but also limitations of CAR-T cell therapy in AML precluding their current routine clinical use. Among a plethora of problems to be overcome, a critical issue will be to find relatively selective actionable targets in AML.
Synthesis and characterization of two-dimensional lead-free (K, Na)NbO3 micro/nano piezoelectric structures

Published: February 2020

AbstractTwo-dimensional (2D) lead-free (K, Na)NbO3 (KNN) micro/nano structures with controllable K/Na ratio were successfully fabricated via a two-step molten salt synthesis (MSS). In this work, the reaction factors, including the proportion of molten salts, the types of carbonates, the sintering temperature, and the sintering time, were discussed in detail and the optimized condition was identified. The microstructure of KNN was confirmed by confocal Raman spectroscopy, while piezoresponse force microscopy (PFM) was applied to measure three-dimensional (3D) morphology and piezoelectric properties of KNN particles. The as-synthesized KNN platelets apparently possess anisotropic morphology and uniform structure, the size of which reaches 5–20 µm in length/width and 0.5–1 µm in thickness. It should be noted that the K/Na ratios of the KNN crystals are basically consistent while the proportion of salts changes within a certain range. The enrichment of Na element in the products is also observed, which owes to the smaller ionic radius of Na+ comparing to that of K+. This result provides a reference for the further preparation of textured ceramics and flexible piezoelectric generators.

AbstractThis investigation demonstrates the feasibility to fabricate high quality ceramic-carbonate membranes based on mixed-conducting ceramics. Specifically, it is reported the simultaneous CO2/O2 permeation and stability properties of membranes constituted by a combination of ceramic and carbonate phases, wherein the microstructure of the ceramic part is composed, in turn, of a mixture of fluorite and perovskite phases. These ceramics showed ionic and electronic conduction, and at the operation temperature, the carbonate phase of the membranes is in liquid state, which allows the transport of $$\rm{CO}_3^{2-}$$CO32− and O2− species via different mechanisms. To fabricate the membranes, the ceramic powders were uniaxially pressed in a disk shape. Then, an incipient sintering treatment was carried out in such a way that a highly porous ceramic was obtained. Afterwards, the piece is densified by the infiltration of molten carbonate. Characterization of the membranes was accomplished by SEM, XRD, and gas permeation techniques among others. Thermal and chemical stability under an atmosphere rich in CO2 was evaluated. CO2/O2 permeation and long-term stability measurements were conducted between 850 and 940 °C.The best permeation-separation performance of membranes of about 1 mm thickness, showed a maximum permeance flux of about 4.46×10−7 mol·m−2·s−2·Pa−1 for CO2 and 2.18×10−7 mol·m−2·s−1·Pa−1 for O2 at 940 °C. Membranes exhibited separation factor values of 150–991 and 49–511 for CO2/N2 and O2/N2 respectively in the studied temperature range. Despite long-term stability test showed certain microstructural changes in the membranes, no significant detriment on the permeation properties was observed along 100 h of continuous operation.

AbstractLead is a potentially harmful element that has caused serious environmental pollution during its mining and use along with serious human health problems. This study assessed lead in Chinese coals based on published literature, with a particular focus on data reported since 2004. The analysis included 9447 individual samples from 103 coalfields or mines in 28 provinces in China. The arithmetic mean content of lead in the studied coals was 15.0 μg/g. Considering the coal reserves, the weighted-average lead concentration in Chinese coals was calculated to be 19.6 μg/g. Lead was significantly enriched in the coals from Henan Province and enriched in the coals from the Tibet Autonomous Region. The coals from Tibet–Western Yunnan and the southern areas of China had elevated lead concentrations. Sulfides are the primary hosts of lead in Chinese coals, although other hosts include silicates, organic matter, carbonates, and other minerals. Source rocks in the sediment-source region and marine environments may be the most significant factors contributing to lead enrichment in Chinese coals. Hydrothermal fluids and peat-forming plants also contribute to lead enrichment in some Chinese coals.
Partial correlation financial networks

Published: February 2020

AbstractCorrelation networks have been a popular way of inferring a financial network due to the simplicity of construction and the ease of interpretability. However two variables which share a common cause can be correlated, leading to the inference of spurious relationships. To solve this we can use partial correlation. In this paper we construct both correlation and partial correlation networks from S&P500 returns and compare and contrast the two. Firstly we show that the partial correlation networks have a smaller and much less variable intensity than the correlation networks, but in fact are less stable. We look at the centrality of the various sectors in the graph using degree centrality and eigenvector centrality, finding that sector centralities move together during the 2009 market crash and that the financial sector generally has a higher mean centrality over most of the dataset. Exploring the use of these centrality measures for portfolio construction, we shown there is mild correlation between the in-sample centrality and the out of sample Sharpe ratio but there is negative correlation between the in-sample centrality and out of sample risk. Finally we use a community detection method to study how the networks reflect the underlying sector structure and study how stable these communities are over time.

ABSTRACTObjective:Hurricane Harvey made landfall on August 25, 2017 and resulted in widespread flooding in Houston and the surrounding areas. This study aimed to explore the associations between exposure to Hurricane Harvey and various mental health symptoms.Methods:Self-reported demographics, hurricane exposure, and mental health symptomatology were obtained from residents of the greater Houston area through convenience sampling for a pilot study, 5 months after the storm from January 25-29, 2018 (N = 161).Results:Increased hurricane exposure score was significantly associated with increased odds for probable depression, probable anxiety, and probable posttraumatic stress disorder after adjusting for other factors associated with mental health. No significant associations were found between demographic characteristics and risk of mental health difficulties.Conclusions:Mental health difficulties associated with exposure to Hurricane Harvey were still present 5 months after the storm. Future disaster response programs should focus on providing long-term mental health services to hurricane survivors.
Place attachment and linguistic variation: A quantitative analysis of language and local attachment in a rural village and an urban social housing area

Published: February 2020

AbstractThis article presents the results of a quantitative analysis of language variation and place attachment in two different places in Denmark—a rural, mono-ethnic village where traditional dialect is still used in everyday practices, and a multiethnic suburban social housing district where speakers use features associated with regional dialect and multiethnic youth styles. It is argued that variationist sociolinguistics, dialect research, as well as sociolinguistics that foregrounds situated interaction analysis need to develop methodologies that include and combine information about speakers’ individual mobility histories, local practices, and future orientations in relation to language use and place. For this purpose, this study employs a quantified measure, anindex of local attachment, of speakers’ attachment to their local area. The index is calculated on the basis of insights from ethnographic fieldwork and interviews, and is compared to the variation of three linguistic variables in each location. Results show differences between the two places, the rural and the urban communities, as well as between individuals that can be explained by differences in place affordances, life histories, and future orientation.
