MEETING THE GREATEST CHALLENGES FOR LEADERS OF THE FUTURE
Authors: Morgan Jacob 
Published: February 2020

AbstractThis article examines my research on the future of leadership. I interviewed over 140 CEOs at companies across industries and worldwide, including Mastercard, Unilever, Oracle, Verizon, Itaú, and Unibanco. Most interviews were done either in person or via 45–60‐minute calls. These CEOs represent over 7 million people, 35 industries, and 20 countries. All of the CEOs were asked 12 questions, such as: What trends will impact the future of leadership? What skills do you think the leader of the future will need to possess and why? What will be some of the greatest challenges for the leader of the future? I also teamed with LinkedIn to survey almost 14,000 of their global members who self‐identified as full‐time employees to compare their perceptions with what CEOs were saying. I interviewed academics, researchers, and coaches and combed through hundreds of case studies, books, articles, and reports on leadership and the future of leadership. In particular, I focus on two categories of challenges, which I call futurize and humanize. Executives quoted include Barri Rafferty, CEO of Ketchum, a global communications consultancy; and Lynn Jurich is the CEO of Sunrun, the United States' leading home solar and energy services company.

ABSTRACTBackgroundVolitional control of involuntary movements has so far been considered a hallmark of tic disorders. However, modulation of involuntary movements can also be observed in other hyperkinesias.CasesHere, we present 6 patients with chorea able to suppress their involuntary movements, on demand. In 3 of them, surface electromyography was used to quantify degree of suppression and confirmed a reduction of muscle activity up to 68%, during volitional control.ConclusionThis observation represents a first step toward a description of a new clinical feature in choreic syndromes and an opportunity to redefine the role of volitional inhibition in hyperkinetic movement disorders.

Abstract
Tagging fish for mark–recapture studies is a common practice in fisheries science that is used to estimate population parameters. However, biased estimates may result from an incomplete understanding of tag retention. The objective of this study was to assess tag retention for a large-river population of Channel Catfish Ictalurus punctatus over a 2,196-d period by using both discrete and instantaneous tag-retention models. A total of 3,827 Channel Catfish were double tagged with T-bar anchor tags in the Red River of the North from 2013 to 2016. The number of tagged Channel Catfish that were recaptured from 2013 to 2019 was 227, with 177 individuals retaining both tags and 50 individuals retaining one tag. Tag retention was estimated at 88% over the study interval by using a discrete tag-retention estimator. An instantaneous tag-retention model suggested that initial tag retention was high, while instantaneous tag shedding was 0.00028 (95% CI = 0.00021 to 0.00038). Based on the instantaneous model, tag retention was predicted as 90% (95% CI = 87% to 93%) at the end of the first year and 54% (95% CI = 44% to 64%) at the end of the study interval. When instantaneous estimates of tag retention are obtained, T-bar anchor tags may be appropriate for studies that evaluate population parameters for Channel Catfish over extended periods.

Published: February 2020

AbstractAimAn evidence‐based approach should permeate clinical nursing practice, but many nurses lack confidence in applying relevant research evidence to clinical practice. Journal club participation can increase evidence‐based practice knowledge and skills while facilitating positive attitudes among participants. Thus, the aim was to describe the experience of nurses in participating in a journal club based on a curriculum derived from their practice narratives.DesignThe study employed a phenomenological hermeneutical approach. Qualitative data from six focus groups with 19 nurses were interpreted in a three‐step process influenced by the French philosopher Paul Ricoeur.MethodsInfluenced by narrative pedagogy and critical reflection through problem‐based learning, a journal club named Reflexivity was facilitated in three 2‐hourly workshops over eight weeks and evaluated together with nurses across three clinical departments.ResultsThree themes are identified: (a) professional reflections are an oppressed aspect of daily nursing; (b) revealing nursing from the hidden; and (c) emerging consciousness in nursing. The study concludes that Reflexivity has the potential to integrate evidence‐based knowledge and increase professional consciousness by reflection on clinical questions in an evidence‐based context. Fundamental issues of nursing care are raised, and feelings of essential pride in nursing are facilitated. Thus, evidence‐based nursing practice is embarked through a journal club based on the participant's narratives.

AbstractThe objective of this investigation is to fabricate hydrogel films comprising sodium carboxymethylcellulose and hydroxypropylmethylcellulose in the presence of citric acid (CA) and zinc oxide nanoparticles (ZnO NPs) by solution casting method. X‐ray diffraction patterns showed that the crystallinity of films decreases and also ZnO crystalline peaks were disappeared with increase in CA concentrations (5‐20 wt%). Fourier transform infrared and micro‐Raman analysis confirmed the absence of Zn‐O vibration. It was found that swelling degree, tensile strength, and initial decomposition temperature of the films decreased with increase in CA. As CA concentration increases, the agglomeration of the NP increases according to field emission scanning electron microscopy and field emission transmission electron microscopy (FETEM) analysis. FETEM‐EDX elemental mapping showed that the NP is composed of C, O, and Zn. The prepared films released zinc and showed significant antibacterial activity against Escherichia coli MTCC 1610 and Staphylococcus aureus MTCC 6538. The fabricated films exhibited biocompatibility with HaCaT cells. The analysis reports that the prepared hydrogel films may be used for potential wound healing applications.
Comparing empowering, transformational, and transactional leadership on supervisory coaching and job performance: A multilevel perspective

Published: February 2020

AbstractWith a leader being able to possess different types of leadership styles, there is a lack of literature investigating which leadership style best facilitates supervisory coaching behavior. The current study aimed to investigate which leadership style would exhibit supervisory coaching behavior, and if supervisory coaching behavior would mediate the relationship between leadership styles and job performance. The study compared the effects of three leadership styles—transformational, transactional, and empowering leadership—on supervisory coaching behavior, which has been reported to influence job performance. A multilevel approach was adopted in this study using 500 employees from 65 organizations within Malaysia. The study found that only empowering and transactional leadership styles exhibited supervisory coaching behavior, which in turn mediated their relationships with job performance. Overall, the findings suggest the importance of leadership styles that prioritize employee development, as these would lead to improved job performance in employees.

AbstractPurposeTo study the risk of preterm birth, caesarean section, and small for gestational age after anti‐tumor necrosis factor agent treatment (anti‐TNF) in pregnancy.MethodsPopulation‐based study including women with inflammatory bowel disease, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and psoriasis, and their infants born 2006 to 2013 from the national health registers in Denmark, Finland, and Sweden. Women treated with anti‐TNF were compared with women with nonbiologic systemic treatment. Adalimumab, etanercept, and infliximab were compared pairwise. Continuation of treatment in early pregnancy was compared with discontinuation. Odds ratios with 95% confidence intervals were calculated in logistic regression models adjusted for country and maternal characteristics.ResultsAmong 1 633 909 births, 1027 infants were to women treated with anti‐TNF and 9399 to women with nonbiologic systemic treatment. Compared with non‐biologic systemic treatment, women with anti‐TNF treatment had a higher risk of preterm birth, odds ratio 1.61 (1.29‐2.02) and caesarean section, 1.57 (1.35‐1.82). The odds ratio for small for gestational age was 1.36 (0.96‐1.92). In pairwise comparisons, infliximab was associated with a higher risk of severely small for gestational age for inflammatory joint and skin diseases but not for inflammatory bowel disease. Discontinuation of anti‐TNF had opposite effects on preterm birth for inflammatory bowel disease and inflammatory joint and skin diseases.ConclusionsAnti‐TNF agents were associated with increased risks of preterm birth, caesarean section, and small for gestational age. However, the diverse findings across disease groups may indicate an association related to the underlying disease activity, rather than to agent‐specific effects.
Evaluation of risk perception, knowledge, and preparedness of extreme storm events for the improvement of coastal resilience among migrants: A lesson from Hong Kong
Authors: Guo Chunlan , Sim Timothy , Ho Hung Chak 
Published: February 2020

AbstractThe severity, intensity, and frequency of extreme storm events facing coastal areas are increasing due to climate change and urban sprawl. Migrant populations are particularly vulnerable in extreme storm events due to resource deficits, a lack of preparedness, and social isolation. Empirical knowledge is needed to help develop comprehensive guidelines to improve coastal resilience for the prevention of adverse impacts from extreme storm events, which should include specific action plans for migrant communities. A cross‐sectional telephone survey was conducted in Hong Kong in July 2018. Most of the 1,015 participants agreed that it was very likely that super typhoons would hit the city in the future. Although most of the migrants under study had lived in Hong Kong for more than 30 years and acquired the local spoken language, there were many significant differences between the migrants and native‐born populations surveyed, notably migrants' comparative lack of knowledge about the tropical cyclone warnings (odds ratio [OR] = 0.320, confidence interval, CI [0.227, 0.451]). Moreover, fewer migrants than native‐born populations had prepared first‐aid kits (OR = 0.583, CI [0.424, 0.801]) or flashlights (OR = 0.412, CI [0.260, 0.655]) at home. A longer migration duration did not change the risk perception or preparedness for a typhoon but did have a significant positive influence on knowledge. In addition, migration played a significant moderating role in enhancing the effect of risk perception on daily disaster preparedness. This research, addressing the needs of migrants in disaster risk reduction, suggests that future research and policy formulation should focus on strengthening migrants' preparedness for typhoons and enhancing their disaster risk literacy.

Published: February 2020

AbstractA unifying framework in defining and measuring resilience has been an intense research topic. In this paper, resilience is measured as a function of intrinsic capacities of a system, the effectiveness of recovery, and the extrinsic random shock process. Some existing resilience measures are analyzed as special cases of the proposed unifying measure. Then, we develop a framework in which the key constituents in achieving resilience are identified. Resilience is represented by four key dimensions: reliability, robustness, recovery, and reconfigurability. Finally, some practical and specific strategies are proposed to enhance the resilience of critical infrastructure systems under the proposed framework.

Published: February 2020

AbstractImpurities present in the electrolyte often interfere with the electrochemical performance of the electrocatalysts. A robust electrocatalyst can provide corrosion resistance towards the poisoning of contaminants in the electrolyzer. In this present work, N doped graphene and graphene with platinum nanoparticles (NPs) composites (RGO−Pt, U‐NGO−Pt, and A‐NGO−Pt) have been studied against chloride ion poisoning on the performance of hydrogen evolution reaction (HER) in acidic medium. Effect of chloride ion poisoning has been studied by adding Cl‐ ion ranging from 0.16 to 0.96 mM in 0.5 M H2SO4 electrolyte solution. Experimental data revealed that the activated N‐ doped graphene oxide (by KOH at 600 °C) and Pt NPs composite imparts the highest Cl‐ corrosion resistance due to the presence of more pyridinic and pyrrolic groups in the N doped graphene‐Pt composite catalyst. Electrochemical studies showed that A‐NGO−Pt displayed the highest exchange current density (3.20 mA cm−2) and it was nearly 1.3 and 7 times higher than that of RGO−Pt (2.43 mA cm−2) and U‐NGO−Pt (0.46 mA cm−2) respectively. Tafel slope for HER was improved from 35.5 (RGO−Pt) to 32.6 mV dec−1 (A‐NGO−Pt), indicating that the doping of N in the graphene plays an important role in the improvement of the catalytic activity of A‐NGO−Pt catalyst. The impedance spectroscopy, chronoamperometry, chronopotentiometry data in presence of 0.96 mM Cl− ion concentration, LSV curves, and ECSA values before after chronoamperometry for A‐NGO−Pt catalyst confirmed that it was a chloride ion‐resistant, stable and durable electrocatalyst for efficient hydrogen generation by the electrochemical water splitting.

AbstractA Ru‐catalyzed method is developed for the synthesis of α‐acyloxy ketones from sulfoxonium ylide and carboxylic acid. The strategy achieves an excellent selectivity in the presence of 1,10‐phenanthroline as ligand to afford the corresponding product in good yields under simple conditions. The reaction is believed to provide an alternative method to generate ester compounds.
Recent Development of Glucosamine‐6‐phosphate Derivatives as Potential Antibacterial Agents
Authors: Liu Xingbang , Ma Shutao 
Published: February 2020

AbstractThe glmS riboswitch (glucosamine‐6‐phosphate activated riboswitch) is located at the 5’‐ untranslated region of the glmS mRNA, which carries the gene of glucosamine‐6‐phosphate (GlcN6P) synthetase named amidotransferase. The glmS riboswitch can bind to its natural coenzyme GlcN6P and lead to its own self‐cleavage, causing the decrease in the expression of the glmS RNA and the synthesis of amidotransferase, and finally, reducing the production of GlcN6P. Since GlcN6P is of vital importance in the metabolic pathway of the bacterial cell wall synthesis, the glmS riboswitch gradually becomes a promising target of antibiotic drugs. In this review, an overview of the development of the glmS riboswitch activators as novel and potent antibacterial agents is described, which involves the structure of the glmS riboswitch and its self‐cleavage mechanism, various the glmS riboswitch activators and their structure‐activity relationships. In particular, the analogs of GlcN6P that can induce self‐cleavage of the glmS riboswitch are highlighted. The most promising compound 9 (Carba‐GlcN6P) exhibited not only excellent activity in inducing the self‐cleavage of the glmS riboswitch, but also great efficacy (kobs=0.153 min−1) at 200 μM compared to GlcN6P (kobs=0.177 min−1).

Published: February 2020

AbstractA novel simple green synthesis route was applied to produce copper oxide (CuO) nanoparticles (NPs) and CuO nanograins (NGs) by using cupric chloride dihydrated as copper salt precursor, curcumin (a natural and non‐toxic food spice) as conjugated agent with or without cetyl trimethylammonium bromide acting as a stabilizing agent at extreme basic condition. Synthesis of this curcumin conjugated CuO nanoparticles was optimized by studying effect of several parameters starting with copper salt precursor, curcumin concentration, pH and temperature. Scanning electron microscopy coupled to Energy Dispersive X‐ray Analyzer, thermogravimetirc analysis, X‐ray diffraction, UV‐visible spectroscopy, fluorescence spectroscopy and zeta potential were used to characterize the resulted CuO NPs/NGs. In this work, the synthesized copper oxide nanograins were found to be efficient nano‐catalysts for the reduction of methylene blue and it was found that nanograin has better catalytic activity compared to spherical shape nanoparticles, emphasizing shape of the CuO particles is crucial for its nanocatalytic activity.

Published: February 2020

AbstractTwo sandwich‐type porphyrin complexes Pd(MeTPP)2 and Pt(MeTPP)2 have been synthesized by the longitudinal coordination of metal ion and porphyrin. The sandwich‐type porphyrin complexes present long triplet lifetime, which is almost 1.4 times longer than the single‐decker porphyrin complexes. Their long triplet lifetimes result in high upconversion quantum yields. An increasing upconversion quantum yield (ΦUC) of up to 29.1 % is obtained under excitation of low power density at 78 mW cm−2. Moreover, porphyrin complexes are used in photoelectrochemical cell to realize sub‐bandgap photo capture and conversion. It is manifested that sandwich‐type structure provides an effective method for porphyrin complexes to enhance the upconversion quantum yield.
Effects of Nanoparticle Electrostatics and Protein–Protein Interactions on Corona Formation: Conformation and Hydrodynamics
Authors: Lee Hwankyu 
Published: February 2020

AbstractAll‐atom molecular dynamics simulations of plasma proteins (human serum albumin, fibrinogen, immunoglobulin gamma‐1 chain‐C, complement C3, and apolipoprotein A‐I) adsorbed onto 10 nm sized cationic, anionic, and neutral polystyrene (PS) particles in water are performed. In simulations of a single protein with a PS particle, proteins eventually bind to all PS particles, regardless of particle charge, in agreement with experiments showing the binding between anionic proteins and particles, which is further confirmed by calculating the binding free energies from umbrella sampling simulations. Simulations of mixtures of multiple proteins and a PS particle show the formation of the protein layer on the surface via the adsorption competition between proteins, which influences the binding affinity and structure of adsorbed proteins. In particular, diffusivities are much higher for proteins bound to the particle surface or to the boundary of the protein layer than for those bound to both the particle surface and other proteins, indicating the dependence of protein mobility on their positions in the layer. These findings help to explain in detail experimental observations regarding the replacement of plasma proteins at the early stage of corona formation and the difference in the binding strength of proteins in inner and outer protein‐layers.
An integrated approach of form finding and construction simulation for glass fiber‐reinforced polymer elastic gridshells
Authors: Xiang Sheng , Cheng Bin , Zou Le , Kookalani Soheila 
Published: February 2020

SummaryGlass fiber‐reinforced polymer (GFRP) elastic gridshell is composed of long continuous GFRP tubes and achieves its shape through the elastic deformations during the lifting construction process. However, the complicated mechanical behaviors during the practical forming process are rarely examined in the previous researches. In this research, an innovative approach consolidating the form‐finding analysis and the construction simulation is proposed for the GFRP elastic gridshells. The integrated approach, which is developed with the ABAQUS and Python, is based on finite element analysis and iterative optimization; therefore, the mechanical deformations of gridshell can be accurately taken into account. The procedure of the integrated analysis is comprehensively presented by taking a typical double‐hump gridshell as an example. The form‐finding results (i.e., the flat lattices) derived from the iteration are found to be insensitive to the initial input. The structural behavior indexes (e.g., deflections, support reactions, and sectional stresses) during the lifting construction process are also available in the analysis. Based on the indexes, some general structural features of such gridshells are concluded. The achievements provide novel perspectives for the form‐finding analysis of GFRP elastic gridshells where lifting construction is involved, which is beneficial for the design and analysis of such structures.

AbstractExcessive intake of high fat diet (HFD) and associated obese conditions are critical contributors of cardiac diseases. In this study, an active metabolite andrographolide from Andrographis paniculata was found to ameliorate HFD‐induced cardiac apoptosis. C57/BL6 mouse were grouped as control (n = 9), obese (n = 8), low dose (25 mg/kg/d) andrographolide treatment (n = 9), and high dose (50 mg/kg/d) andrographolide treatment (n = 9). The control group was provided with standard laboratory chow and the other groups were fed with HFD. Andrographolide was administered through oral gavage for 1 week. Histopathological analysis showed increase in apoptotic nuclei and considerable cardiac‐damages in the obese group signifying cardiac remodeling effects. Further, Western blot results showed increase in pro‐apoptotic proteins and decrease in the proteins of IGF‐1R‐survival signaling. However, feeding of andrographolide significantly reduced the cardiac effects of HFD. The results strongly suggest that andrographolide supplementation can be used for prevention and treatment of cardiovascular disease in obese patients.
