It might be ethical, but I won't buy it: Perceived contamination of, and disgust towards, clothing made from recycled plastic bottles
Authors: Meng Matthew D. , Leary R. Bret 
Published: December 2019

AbstractA popular trend within the fashion industry is to transform recycled plastic bottles into attire, though little research has examined consumer acceptance of these items. This study integrates evolutionary perspectives on contagion, contamination, and the emotion of disgust to explore consumer perception of such goods. Across three studies, this study shows that consumers view products made from used recycled plastic bottles as contaminated, decreasing purchase intentions. Further, this contamination perception is heightened among those with high disgust sensitivity. This study also shows an important boundary condition to this effect, where consumers express greater intentions to use a product made from recycled plastic bottles when it is not touching the skin (e.g., carrying bag) compared to those that are in contact with skin (e.g., T‐shirt). Finally, this study shows how marketers can harness this effect by exploiting the evolutionary response to attractive others using the plastic bottles, which results in positive contamination and an increase in willingness to pay. In so doing, the current research is the first to show that highlighting the recycled nature of a product can actually serve as a contamination cue, adding to our theoretical understanding of perceived contamination and the resulting emotion of disgust.
Education and visual neuroscience: A mini‐review
Authors: Chen Lihan 
Published: December 2019

AbstractNeuroscience, especially visual neuroscience, is a burgeoning field that has greatly shaped the format and efficacy of education. Moreover, findings from visual neuroscience are an ongoing source of great progress in pedagogy. In this mini‐review, I review existing evidence and areas of active research to describe the fundamental questions and general applications for visual neuroscience as it applies to education. First, I categorize the research questions and future directions for the role of visual neuroscience in education. Second, I juxtapose opposing views on the roles of neuroscience in education and reveal the “neuromyths” propagated under the guise of educational neuroscience. Third, I summarize the policies and practices applied in different countries and for different age ranges. Fourth, I address and discuss the merits of visual neuroscience in art education and of visual perception theories (e.g., those concerned with perceptual organization with respect to space and time) in reading education. I consider how vision‐deprived students could benefit from current knowledge of brain plasticity and visual rehabilitation methods involving compensation from other sensory systems. I also consider the potential educational value of instructional methods based on statistical learning in the visual domain. Finally, I outline the accepted translational framework for applying findings from educational neuroscience to pedagogical theory.
Structural insights into phosphopantetheinyl hydrolase PptH from Mycobacterium tuberculosis

Published: December 2019

AbstractThe amidinourea 8918 was recently reported to inhibit the type II phosphopantetheinyl transferase (PPTase) of Mycobacterium tuberculosis (Mtb), PptT, a potential drug‐target that activates synthases and synthetases involved in cell wall biosynthesis and secondary metabolism. Surprisingly, high‐level resistance to 8918 occurred in Mtb harboring mutations within the gene adjacent to pptT, rv2795c, highlighting the role of the encoded protein as a potentiator of the bactericidal action of the amidinourea. Those studies revealed that Rv2795c (PptH) is a phosphopantetheinyl (PpT) hydrolase, possessing activity antagonistic with respect to PptT. We have solved the crystal structure of Mtb's phosphopantetheinyl hydrolase, making it the first phosphopantetheinyl (carrier protein) hydrolase structurally characterized. The 2.5 Å structure revealed the hydrolases' four‐layer (α/β/β/α) sandwich fold featuring a Mn‐Fe binuclear center within the active site. A structural similarity search confirmed that PptH most closely resembles previously characterized metallophosphoesterases (MPEs), particularly within the vicinity of the active site, suggesting that it may utilize a similar catalytic mechanism. In addition, analysis of the structure has allowed for the rationalization of the previously reported PptH mutations associated with 8918‐resistance. Notably, differences in the sequences and predicted structural characteristics of the PpT hydrolases PptH of Mtb and E. coli's acyl carrier protein hydrolase (AcpH) indicate that the two enzymes evolved convergently and therefore are representative of two distinct PpT hydrolase families.

AbstractOur information‐driven docking approach HADDOCK has demonstrated a sustained performance since the start of its participation to CAPRI. This is due, in part, to its ability to integrate data into the modeling process, and to the robustness of its scoring function. We participated in CAPRI both as server and manual predictors. In CAPRI rounds 38‐45, we have used various strategies depending on the available information. These ranged from imposing restraints to a few residues identified from literature as being important for the interaction, to binding pockets identified from homologous complexes or template‐based refinement/CA‐CA restraint‐guided docking from identified templates. When relevant, symmetry restraints were used to limit the conformational sampling. We also tested for a large decamer target a new implementation of the MARTINI coarse‐grained force field in HADDOCK. Overall, we obtained acceptable or better predictions for 13 and 11 server and manual submissions, respectively, out of the 22 interfaces. Our server performance (acceptable or higher‐quality models when considering the top 10) was better (59%) than the manual (50%) one, in which we typically experiment with various combinations of protocols and data sources. Again, our simple scoring function based on a linear combination of intermolecular van der Waals and electrostatic energies and an empirical desolvation term demonstrated a good performance in the scoring experiment with a 63% success rate across all 22 interfaces. An analysis of model quality indicates that, while we are consistently performing well in generating acceptable models, there is room for improvement for generating/identifying higher quality models.
Aromaticity of N‐heterocyclic carbene and its analogues: Magnetically induced ring current perspective
Authors: Patra Shanti G. , Mandal Nilangshu 
Published: December 2019

AbstractThe N‐heterocyclic carbene, imidazole‐2‐ylidene, and its main group (13‐15) analogues contain cyclically conjugated 6π electrons. Experimental 1H nuclear magnetic resonance (NMR) spectra suggest an increase in aromaticity along a period from left to right. Whereas the order along a group is as follows: period 2 > period 5 > period 4 > period 3 due to change in structure. To understand the order of aromaticity, the magnetically induced ring currents of the molecules are calculated using aromatic ring current shielding, gauge‐including magnetically induced currents (GIMIC) method and Stanger's σ‐model applying the gauge‐including atomic orbitals NMR technique. It is found that GIMIC best describes the order of aromaticity especially along a group where current‐profile changes on the bivalent atom down a group due to change in electron density. Moreover, the GIMIC provides the visualization of current by sign modulus and the anisotropy of the induced current density plots.
Sum‐of‐squares–based consensus verification for directed networks with nonlinear protocols
Authors: Liang Quanyi , Ong Chong‐Jin , She Zhikun 
Published: December 2019

SummaryIn this paper, we investigate the consensus verification problem of nonlinear agents in a fixed directed network with a nonlinear protocol. Inspired by the classical Lipschitz‐like condition, we introduce a more relax condition for the dynamics of the nonlinear agents. This condition is motivated via the construction of general Lyapunov functions for achieving asymptotic consensus. Especially, for agents where dynamics are described by polynomial function of the states, our consensus criterion can be converted to a sum of squares (SOS) programming problem, solvable via semidefinite programming tools. Of interest is that the scale of the resulting SOS programming problem does not increase as the size of the network increases, and thus, the applicability to analyze consensus of large‐scale networks is promising. Finally, an example is given to illustrate the effectiveness of our theoretical results.
Regaining tractability through reframing of a watershed management conflict: A case of southwestern Puerto Rico
Authors: Santiago Luis , Hong Chang‐Yu 
Published: December 2019

AbstractThe Río Loco watershed in southwestern Puerto Rico is a site where significant coastal development has taken place and water is currently used for residential purposes, power generation and agricultural production. Competing uses and resulting tradeoffs have led to conflict among the watershed's stakeholders, and a proposed natural resource conservation measure in the area has exacerbated conflict to the point where it can be described as intractable. We propose a two‐phase conflict resolution scheme: the first phase requires gaining tractability by reframing the problem considering mainly diagnostic parameters, and the second phase outlines a series of processes that may help manage conflict once the problem becomes tractable. We conducted two focus groups with key stakeholders in the Río Loco watershed, including farmers and conservationists representing NGO's, public and private organizations to assess current frames. Through the reframed interests, we conclude innovative institutions or flexible organizations will be able to provide a new arena where conversations take place, thus, creating a space for a more inclusive and democratic process to manage the watershed in the short and long term, and at the same time increasing chances of maintaining problems within the realm of tractability.

Abstract
Cardiac interstitial cells (CICs) perform essential roles in myocardial biology through preservation of homeostasis as well as response to injury or stress. Studies of murine CIC biology reveal remarkable plasticity in terms of transcriptional reprogramming and ploidy state with important implications for function. Despite over a decade of characterization and in vivo utilization of adult c-Kit+ CIC (cCIC), adaptability and functional responses upon delivery to adult mammalian hearts remain poorly understood. Limitations of characterizing cCIC biology following in vitro expansion and adoptive transfer into the adult heart were circumvented by delivery of the donated cells into early cardiogenic environments of embryonic, fetal, and early postnatal developing hearts. These three developmental stages were permissive for retention and persistence, enabling phenotypic evaluation of in vitro expanded cCICs after delivery as well as tissue response following introduction to the host environment. Embryonic blastocyst environment prompted cCIC integration into trophectoderm as well as persistence in amniochorionic membrane. Delivery to fetal myocardium yielded cCIC perivascular localization with fibroblast-like phenotype, similar to cCICs introduced to postnatal P3 heart with persistent cell cycle activity for up to 4 weeks. Fibroblast-like phenotype of exogenously transferred cCICs in fetal and postnatal cardiogenic environments is consistent with inability to contribute directly toward cardiogenesis and lack of functional integration with host myocardium. In contrast, cCICs incorporation into extra-embryonic membranes is consistent with fate of polyploid cells in blastocysts. These findings provide insight into cCIC biology, their inherent predisposition toward fibroblast fates in cardiogenic environments, and remarkable participation in extra-embryonic tissue formation.

Significance statement Biological properties and functional activities of adult cardiac interstitial cells continue to elude simple characterization despite decades of investigation. The present study demonstrates the influence of developmental environmental cues upon phenotypic properties of c-Kit+ adult cardiac interstitial cells (cCICs). Delivery of cCIC into early embryonic blastocysts leads to trophectoderm integration with exclusion from the inner cell mass, whereas introduction of cCIC into developing myocardium of late fetal or early postnatal hearts results in extended persistence and acquisition of phenotypic traits consistent with fibroblasts. Findings of the present study support the rationale for cCIC cell therapy in the context of congenital and pediatric cardiomyopathic conditions.
Investigation of the properties of two different slag‐based geopolymer concretes exposed to freeze–thaw cycles
Authors: Özdal Mustafa , Karakoç Mehmet Burhan , Özcan Ahmet 
Published: December 2019

AbstractFerrochrome slag (FS) and ground granulated blast furnace slag (GGBFS) were used as resource material in geopolymer concrete mixtures. A mixture of 10 M sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) was used as the activator. After the two different slag‐based geopolymer concrete (SGC) mixtures were prepared and molded. They were kept at 80°C for 24 hr, and then the SGC samples were cured in 23 ± 1°C water for 27 days. Samples that completed the curing times were exposed to the 300 freeze–thaw (F–T) cycles. The compressive strength, ultrasonic pulse velocity, relative dynamic elasticity modulus values, weight changes, and appearances of the SGC samples were examined at the end of every 50 F–T cycles. Scanning electron microscopy analysis was performed to examine the microstructure changes of the samples after 300 F–T cycles. As the GGBFS proportion in the SGC mix increased, the mechanical properties of the samples against the F–T effect increased. Samples containing 100% FS and 75% FS fell apart at the end of 150 and 200 F–T cycles, respectively. The deterioration of the geopolymer gel structures of the samples exposed to F–T was decreased with increasing GGBFS ratio in the mix.
Profiles of middle school science teachers: Accounting for cognitive and motivational characteristics

Published: December 2019

AbstractTeachers play a critical role in successfully implementing science education reforms in the United States to provide high‐quality science learning opportunities to all students. However, the differentiated ways in which teachers make decisions about their science teaching are not well understood. This study takes a person‐centered approach by applying latent profile analysis to examine how cognitive (pedagogical content knowledge) and motivational (instructional goal orientations, self‐efficacy beliefs, and reform values) characteristics combine to form science teacher profiles in middle school. Predictors of profile membership (bachelor's degree, school %FRL) and both teacher (science instructional practices) and student (science achievement, engagement, and self‐efficacy) outcomes related to the teacher profiles were also examined. Five science teacher profiles were identified (severely discouraged but reform oriented, discouraged but reform oriented, conventional, confident and mastery oriented, and confident with multiple goal approaches) that represented unique configurations of cognitive and motivation characteristics. Additionally, findings showed that the teacher profiles were significantly related to three dimensions of science instructional practice including communication, discourse, and reasoning. Finally, the teacher profiles were significantly related to student science achievement and motivational outcomes. Implications for differentiated approaches to teacher professional learning and supports for science instruction are discussed.
Global strategy gone astray: Maersk's big box boats and the world shipping industry
Authors: Anwar Syed Tariq 
Published: December 2019

AbstractA.P. Moller‐Maersk Group (A.P. Moller‐Mærsk AS in Danish), commonly known as Maersk, is the world's largest global shipping conglomerate from Denmark and carries a rich history and corporate heritage in the industry. The company operates large container ships which are mostly known as “big box boats” in the industry. By using interdisciplinary literature and the shipping industry's operational routes and corporate developments, this case‐based research analyzes and discusses Maersk's internationalization and its global strategies. Although Maersk aggressively sought internationalization and company‐specific expansion, its global strategy and international expansion areas have encountered problems because of the slowdown of the global economy, de‐globalization, and the U.S.–China trade tussle. The case‐based research analyzes and discusses these issues within the areas of international business and the company's global strategies and industry‐specific competition. Analysts and industry observers believe that Maersk will continue to be a major shipping and logistics firm and will thrive in global markets. At the same time, the company will be impacted by the changing competition, regulatory forces, and new technologies in logistics and global shipping. This case study also provides future developments and growth prospects of Maersk and the shipping industry.
Terrorism as an external threat factor in global value chains
Authors: Bader Benjamin , Suder Gabriele , Grosse Robert 
Published: December 2019

AbstractGlobal terrorism incidents and business‐related threats have intensified in scale and scope over the past 17 years. Multinational corporations are thus exposed to direct and indirect negative impacts on their international activities. Previous research lacks thorough theoretical frameworks to analyze these impacts. The global value chain (GVC) framework offers a perspective that is both comprehensive and quantifiable for the evaluation and expansion of this prior research. The GVC enables us to assess terrorism impacts on international business overall and at each stage of the value chain. On this basis, we develop a “terrorism resilience theory”) that can be used in future theoretical and managerial analyses of the response to terrorism risk.
Biogas production from slaughterhouse wastewaters and use of biofertilizer obtained for biodegradation of aromatic hydrocarbons
Authors: Marder Munique , Konrad Odorico , Ilha Vinicius , Granada Camille Eichelberger 
Published: December 2019

AbstractThe anaerobic digestion of industrial wastes produces a biogas that is an alternative to the use of fossil fuels for energy production. At the end of this process, the stabilized biomass presents high levels of nutrients, which can be used both as biofertilizers in agriculture and for the biodegradation of contaminants in the soil through improvement of the microbiota. Thus, this study aimed to evaluate biogas production by industrial wastes and to use the biofertilizer for the bioremediation of soils previously contaminated with gasoline. The biomass (420 mL) generated approximately 10 liters (L) of methane and 3 L of other gases. Anaerobic incubation reduced total and volatile solids, as well as biochemical oxygen demand, chemical oxygen demand, and the carbon and nitrogen contents of the biomass. The bioremediation experiment showed that 15 days after contamination with gasoline, the addition of the biofertilizer improved the degradation efficiency of monoaromatic hydrocarbons; however, the degradation of polyaromatic hydrocarbons was less time efficient. So, we conclude that the anaerobic incubation of industrial wastes generates a high amount of biogas, and that biofertilizer deposition into contaminated soil does not affect the efficiency of the degradation of aromatic hydrocarbons after 30 days. Novelty or significance: Anaerobic incubation of industrial wastes generates a high calorific value gas, which can be used as an alternative source of energy. And, the resulting biomass, called biofertilizer, can be used to remediate soils contaminated with hydrocarbons.
Acoustic Surveys for Bats are Improved by Taking Habitat Type into Account
Authors: Findlay Stephanie V. , Barclay Robert M. R. 
Published: December 2019

ABSTRACTPassive monitoring of bat species via acoustics is a growing field and as a result there are various software programs available that allow for species identification. However, accuracy of these programs is variable and creating a local call library is essential when trying to identify acoustically similar species. In Dinosaur Provincial Park, Alberta, Canada, 3 Myotis species are difficult to distinguish acoustically. We created an echolocation call library from known Myotis evotis, M. lucifugus, and M. ciliolabrum flying in open spaces and near clutter to test whether or not recording in the bats' local habitat type improved call library quality and identification accuracy. Bat calls recorded within open spaces (coulees) differed from those recorded near cluttered spaces (tree edges) for M. ciliolabrum and M. lucifugus. Accuracy of species identification also increased when we used models based on bat calls recorded in cluttered habitats. Using a simple model with recordings from different habitat types within a study site, we were able to improve identification accuracy and model performance. © 2019 The Wildlife Society.
