Different Measures of Print Exposure Predict Different Aspects of Vocabulary
Authors: Zhang Su Zhen , Georgiou George K. , Xu Jining , Liu Jian Mei , Li Miao , Shu Hua 
Published: September 2017

AbstractThe authors examined whether different measures of print exposure assess the same underlying concept and how these different measures relate to vocabulary breadth and depth. One hundred forty‐seven students attending the third year of kindergarten in Jining, China, were assessed on nonverbal IQ, vocabulary breadth and depth, and their knowledge of book titles. Parents also participated in the study by filling out a questionnaire on the frequency of shared book reading and the number of children's books at home, recording their daily parent–child reading activities (diary), and completing the children's title and author recognition checklists. Results of exploratory factor analysis indicated that the measures of print exposure were loading on three interrelated factors. The items measuring the frequency of shared book reading at home along with diary formed one factor, the children's title recognition checklist and number of children's books at home formed a second factor, and children's knowledge of book titles formed a third factor. In addition, the results of hierarchical regression analyses indicated that whereas all factors accounted for unique variance (3–6%) in vocabulary breadth, only children's knowledge of book titles predicted vocabulary depth, after controlling for children's age, parents’ education and income, and children's nonverbal IQ. Taken together, these findings suggest that different measures of print exposure may capture different aspects of print exposure and that these aspects may exert a different role in vocabulary breadth and depth.

Authors: Constantino L. V. , Lopes E. T. , Frachini E. C. , Monteiro A. M. , Santos M. J. 
Published: September 2017

Herein is reported the application of models on sorption isotherms for removal of silver ions from aqueous solution using 2 bentonites: SWy‐2 and BaVC‐1, low‐cost sorbents. Physicochemical attributes were determined for both materials, and sorption experiments were carried out in batch system. The pH before and after sorption decreased from 7.8 to 6.1 and 8.4 to 6.7 for SWy‐2 and BaVC‐1, respectively. Langmuir, Freundlich, Sips, Toth, Kolbe‐Corrigan, Khan, and Radke‐Prausnitiz models were applied to the data. The models showed good fit with R2 above 0.999 and RMSE < 2%. The adjustable parameters indicated high affinity of silver ions to BaVC‐1 sorption sites, demonstrating high sorption capacity and thermodynamic feasibility. In general, SWy‐2 showed most heterogeneous sorption sites, while BaVC‐1 showed most homogeneous sites. Moreover, BaVC‐1 has shown larger surface area and smaller particle size, which can explain its better sorption performance as compared with SWy‐2.

Authors: Lu Fei , Zhou Min , Zhou Yuxue , Zeng Xianghua 
Published: September 2017

AbstractOwing to its abundance, high gravimetric energy density, and environmental friendliness, hydrogen is a promising renewable energy to replace fossil fuels. One of the most prominent routes toward hydrogen acquisition is water splitting, which is currently bottlenecked by the sluggish kinetics of oxygen evolution reaction (OER). Numerous of electrocatalysts have been developed in the past decades to accelerate the OER process. Up to now, the first‐row transition metal based compounds are in pole position under alkaline conditions, which have become subjects of extensive studies. Recently, significant advances in providing compelling catalytic performance as well as exploring their catalytic mechanisms have been achieved in this area. In this review, we summarized the fundamentals and recent progresses in first‐row transition metal based OER catalysts, with special emphasis on the pathways of promoting catalytic performance by concrete strategies. New insight into material design, particularly the role of experimental approaches in the electrocatalytic performance and reaction mechanisms of OER are expected to be provided.
Optimizing Energy Transduction of Fluctuating Signals with Nanofluidic Diodes and Load Capacitors

Published: September 2017

AbstractThe design and experimental implementation of hybrid circuits is considered allowing charge transfer and energy conversion between nanofluidic diodes in aqueous ionic solutions and conventional electronic elements such as capacitors. The fundamental concepts involved are reviewed for the case of fluctuating zero‐average external potentials acting on single pore and multipore membranes. This problem is relevant to electrochemical energy conversion and storage, the stimulus‐response characteristics of nanosensors and actuators, and the estimation of the accumulative effects caused by external signals on biological ion channels. Half‐wave and full‐wave voltage doublers and quadruplers can scale up the transduction between ionic and electronic signals. The network designs discussed here should be useful to convert the weak signals characteristic of the micro and nanoscale into robust electronic responses by interconnecting iontronics and electronic elements.
Mesenchymal Stem Cells: The Moniker Fits the Science
Authors: Boregowda Siddaraju V. , Booker Cori N. , Phinney Donald G. 
Published: September 2017

Abstract
Mesenchymal stem cells (MSCs) have gained widespread use in regenerative medicine due to their demonstrated efficacy in a broad range of experimental animal models of disease and their excellent safety profile in human clinical trials. Outcomes from these studies suggest that MSCs achieve therapeutic effects in vivo in nonhomologous applications predominantly by paracrine action. This paracrine-centric viewpoint has become widely entrenched in the field, and has spurred a campaign to rename MSCs as “medicinal signaling cells” to better reflect this mode of action. In this Commentary, we argue that the paracrine-centric viewpoint and proposed name change ignores a wealth of old and new data that unequivocally demonstrate the stem cell nature of MSCs, and also overlooks a large effort to exploit homologous applications of MSCs in human clinical trials. Furthermore, we offer evidence that a stem cell-centric viewpoint of MSCs provides a comprehensive understanding of MSC biology that encompasses their paracrine activity, and provides a better foundation to develop metrics that quantify the biological potency of MSC batches for both homologous and nonhomologous clinical applications.
Angiotensin‐(1‐7)‐mediated Mas1 receptor/NF‐κB‐p65 signaling is involved in a cigarette smoke‐induced chronic obstructive pulmonary disease mouse model
Authors: Zhang Yong , Li Yang , Shi Ce , Fu Xiaomin , Zhao Lingdi , Song Yongping 
Published: September 2017

AbstractAngiotensin‐(1‐7) [Ang‐(1‐7)] has been shown to play a significant role in the pathogenesis of lung inflammation via Mas receptor; however, its effect in chronic obstructive pulmonary disease (COPD) remains unknown. To explore the effect of Ang‐(1‐7) on a cigarette smoke (CS) exposure‐induced COPD model, 40 C57BL/6J mice were divided into four groups (n = 10) and exposed to air or CS for 8 weeks. After that, they were treated with saline or Ang‐(1‐7) at 0.3 mg/kg for 2 weeks by subcutaneous infusion using osmotic pump. The day following drug/vehicle challenge, lung function was examined and bronchoalveolar lavage (BAL) was performed. Chemokine (C–X–C motif) ligand 1, interleukin‐6, and tumor necrosis factor‐α protein levels in BAL fluid were determined using ELISA; the corresponding mRNA levels in lung tissues were measured using RT‐PCR. Mas1 receptor, pIκBα, IκBα, nuclear NF‐κB‐p65 protein, pERK1/2, ERK2, pp38, and p38 proteins expression in lung tissues were examined by immunohistochemical staining and western blotting. Ang‐(1‐7) challenge had no effect on the decreased lung function and emphysema induced by CS exposure. However, Ang‐(1‐7) treatment blocked CS exposure‐induced lung inflammatory responses and lung fibrosis, as determined by Masson's Trichrome staining. Exposure to CS for 8 weeks caused irreversible loss of lung function and emphysema, which could not be reversed by Ang‐(1‐7) treatment. Thus, the beneficial effect of Ang‐(1‐7) may be confined to pulmonary inflammation and fibrosis.
A tale of Mexico's most exploited—and connected—watersheds: the Basin of Mexico and the Lerma‐Chapala Basin
Authors: Carrera‐Hernandez Jaime J. 
Published: September 2017

Water management policies and their impacts for both the Basin of Mexico and the Lerma‐Chapala basin—where nearly 25% of Mexico's inhabitants are found—are described. This work shows that the prevailing water management policy has been the augmentation of water supply and neither policies have focused on water savings nor management of water demand. The effects of the large extraction rates on both basins have caused drying‐up of streams due to drawdown rates that reach 2.5 m/year with an associated land subsidence in different cities in these basins. Water management in Mexico needs to change from a water supply approach to a water efficiency approach, where water needs to be efficiently used. Water management will only improve when policies consider both technical and social perspectives. WIREs Water 2018, 5:e1247. doi: 10.1002/wat2.1247This article is categorized under:

The COSMO and COSMO‐RS solvation models
Authors: Klamt Andreas 
Published: September 2017

The conductor‐like screening model COSMO, a variant of the dielectric continuum solvation models, has become very popular due to its algorithmic simplicity, numerical stability, and its great insensitivity with respect to outlying charge errors. The advanced model COSMO‐RS, i.e., COSMO for realistic solvation, is a statistical thermodynamics theory based on COSMO polarization charge densities, which overcomes many of the limitations and theoretical shortcomings of dielectric continuum models. Due to its ability to treat mixtures at variable temperatures, it has become very popular in chemical engineering and in wide areas of physical and medicinal chemistry. COSMO‐RS may currently be considered the most accurate model for the prediction of solvation energies. This article provides a short description of the basic concepts of both models, of the differences with other solvation models, and of their application areas. Finally, Direct‐COSMO‐RS, a recent direct integration of the COSMO‐RS concept into quantum chemical calculations, is briefly described.

Real‐time time‐dependent electronic structure theory
Authors: Goings Joshua J. , Lestrange Patrick J. , Li Xiaosong 
Published: September 2017

Real‐time time‐dependent electronic structure theory is one of the most promising methods for investigating time‐dependent molecular responses and electronic dynamics. Since its first modern use in the 1990s, it has been used to study a wide variety of spectroscopic properties and electronic responses to intense external electromagnetic fields, complex environments, and open quantum systems. It has also been used to study molecular conductance, excited state dynamics, ionization, and nonlinear optical effects. Real‐time techniques describe non‐perturbative responses of molecules, allowing for studies that go above and beyond the more traditional energy‐ or frequency‐domain‐based response theories. Recent progress in signal analysis, accurate treatment of environmental responses, relativistic Hamiltonians, and even quantized electromagnetic fields have opened up new avenues of research in time‐dependent molecular response. After discussing the history of real‐time methods, we explore some of the necessary mathematical theory behind the methods, and then survey a wide (yet incomplete) variety of applications for real‐time methods. We then present some brief remarks on the future of real‐time time‐dependent electronic structure theory. WIREs Comput Mol Sci 2018, 8:e1341. doi: 10.1002/wcms.1341This article is categorized under:

Estimation of covariance and precision matrix, network structure, and a view toward systems biology
Authors: Kuismin Markku O. , Sillanpää Mikko J. 
Published: September 2017

Covariance matrix and its inverse, known as the precision matrix, have many applications in multivariate analysis because their elements can exhibit the variance, correlation, covariance, and conditional independence between variables. The practice of estimating the precision matrix directly without involving any matrix inversion has obtained significant attention in the literature. We review the methods that have been implemented in R and their R packages, particularly when there are more variables than data samples and discuss ideas behind them. We describe how sparse precision matrix estimation methods can be used to infer network structure. Finally, we discuss methods that are suitable for gene coexpression network construction.WIREs Comput Stat2017, 9:e1415. doi: 10.1002/wics.1415This article is categorized under:Statistical Models > Linear ModelsApplications of Computational Statistics > Computational and Molecular BiologyStatistical and Graphical Methods of Data Analysis > Multivariate Analysis
Better bullets to shoot small mammals without poisoning scavengers
Authors: McTee Michael , Young Matt , Umansky Andre , Ramsey Philip 
Published: September 2017

ABSTRACTRecreational shooters kill millions of small mammals each year and scavengers that ingest the carcasses can be poisoned if lead bullets are used. Less toxic bullets exist, but their performance and potential risk to deposit lead in carcasses is understudied. In May 2016, shooters controlled populations of Columbian ground squirrels (Urocitellus columbianus) at ranches in Idaho and Montana, USA, by shooting them with .17 HMR (Hornady Magnum Rimfire), .22 LR (long rifle), and .223 Rem (Remington) rifles with expanding and nonexpanding lead and nonlead bullets. We recorded whether bullets instantly incapacitated ground squirrels and then counted the number of bullet fragments in each carcass to estimate concentrations of residual lead. All types of lead bullets left lead in at least one‐third of the Columbian ground squirrels. Unexpectedly, estimated concentrations of lead in carcasses did not differ between expanding and nonexpanding bullets within the .17 HMR and .22 LR calibers, partially because of the high variability in fragmentation. The greatest estimated concentrations of lead were in Columbian ground squirrels shot with expanding ammunition in .17 HMR and .223 Rem, which had an average of 23.6 mg and 91.2 mg Pb/carcass, respectively. Nonlead bullets incapacitated similar to lead bullets. Our results indicate that nonlead bullets eliminate the risk of additional lead exposure to scavengers while maintaining the lethality of lead bullets. © 2017 The Wildlife Society.
Surgical Head Coverings: A Literature Review
Authors: Spruce Lisa 
Published: September 2017

AbstractMicroorganisms that cause surgical site infections may either be present on the patient's skin or mucous membranes or transmitted to the patient by health care personnel, the environment, or other items in the perioperative setting. This literature review analyzes the evidence used to support the recommendation that perioperative personnel should cover their heads, hair, and ears in the semirestricted and restricted areas. A literature search produced 27 articles related to bacterial shedding from skin and hair, pathogenic organisms present on the hair and ears, and case reports of infectious organisms passed from health care providers to patients. Although there is no conclusive evidence that wearing a head covering can help prevent surgical site infections, the potential benefits to patients when compared with the risks suggest that perioperative team members should cover their heads, hair, and ears in the semirestricted and restricted areas to provide the best possible protection for surgical patients.
The Role of Emotional Intelligence in Perioperative Nursing and Leadership: Developing Skills for Improved Performance
Authors: Beydler Kathy Williams 
Published: September 2017

AbstractMany responsibilities of perioperative professionals involve concrete tasks that require high technical competence. Emotional intelligence, referred to as EQ, which involves the ability to relate to and influence others, may also be important for perioperative professionals. High EQ has been linked to higher performance in the workplace, higher job satisfaction, lower turnover intentions, and less burnout. Perioperative professionals who demonstrate a combination of technical skills and EQ could be more attuned to the humanity of health care (ie, providing more holistic care for the patient). Perioperative nurses who value providing holistic care for their patients may possess many of the elements of EQ. Leaders who recognize the importance of their own EQ and actively assist staff members to enhance and develop their EQ competency may help to create a competitive advantage by establishing a workforce of nurses who possess strong technical skills and high EQ.

Published: September 2017

AbstractPatient safety in the OR depends on effective communication. We developed and tested a communication training program for surgical oncology staff members to increase communication about patient safety concerns. In phase one, 34 staff members participated in focus groups to identify and rank factors that affect speaking‐up behavior. We compiled ranked items into thematic categories that included role relations and hierarchy, staff rapport, perceived competence, perceived efficacy of speaking up, staff personality, fear of retaliation, institutional regulations, and time pressure. We then developed a communication training program that 42 participants completed during phase two. Participants offered favorable ratings of the usefulness and perceived effect of the training. Participants reported significant improvement in communicating patient safety concerns (t40 = –2.76, P = .009, d = 0.48). Findings offer insight into communication challenges experienced by surgical oncology staff members and suggest that our training demonstrates the potential to improve team communication.

Published: September 2017

AbstractWe undertook an integrative literature review of articles pertaining to perioperative nursing care provided to patients using postoperative accelerated recovery protocols. To select the articles, we searched the MEDLINE, PubMed, Cumulative Index to Nursing and Allied Health Literature, and Literatura Latino‐Americana e do Caribe em Ciências da Saúde databases. We identified 329 studies, 13 of which met our inclusion criteria and described perioperative nursing care activities. Nursing activities noted in these articles were hypothermia prevention and maintenance of normothermia, restriction of IV fluids, assessment of vital signs, management of symptoms and pain, support of early ambulation, care for tubes and drains, oral administration of carbohydrate‐rich foods, assessment of ability to tolerate diet, and encouragement to resume activities of daily living. There was a lack of research on this topic by nursing professionals; additional research by nursing professionals is needed regarding nurses’ roles in providing this care.

Humean Laws in an unHumean World
Authors: KIMPTON-NYE SAMUEL 
Published: September 2017

ABSTRACT:I argue that anunHumeanontology of irreducibly dispositional properties might be fruitfully combined with what has typically been thought of as aHumeanaccount of laws, namely, thebest-system account, made popular by David Lewis (e.g., 1983, 1986, 1994). In this paper I provide the details of what I argue is the most defensible account of Humean laws in an unHumean world. This package of views has the benefits of upholding scientific realism while doing without any suspect metaphysical entities to account for natural law. I conclude by arguing that the Humean laws-unHumean ontology package is well placed to provide an account of objective, nontrivialchances, a famous stumbling block for the Humean laws-Humean ontology package developed by Lewis.

AbstractHealthy adults (n30) participated in a placebo-controlled, randomised, double-blinded, cross-over study consisting of two 28 d treatments (β2-1 fructan or maltodextrin; 3×5 g/d) separated by a 14-d washout. Subjects provided 1 d faecal collections at days 0 and 28 of each treatment. The ability of faecal bacteria to metaboliseβ2-1 fructan was common; eighty-seven species (thirty genera, and four phyla) were isolated using anaerobic medium containingβ2-1 fructan as the sole carbohydrate source.β2-1 fructan altered the faecal community as determined through analysis of terminal restriction fragment length polymorphisms and 16S rRNA genes. Supplementation withβ2-1 fructan reduced faecal community richness, and two patterns of community change were observed. In most subjects,β2-1 fructan reduced the content of phylotypes aligning within theBacteroides, whereas increasing those aligning within bifidobacteria,Faecalibacteriumand the family Lachnospiraceae. In the remaining subjects, supplementation increased the abundance of Bacteroidetes and to a lesser extent bifidobacteria, accompanied by decreases within theFaecalibacteriumand family Lachnospiraceae.β2-1 Fructan had no impact on the metagenome or glycoside hydrolase profiles in faeces from four subjects. Few relationships were found between the faecal bacterial community and various host parameters; Bacteroidetes content correlated with faecal propionate, subjects whose faecal community contained higher Bacteroidetes produced more caproic acid independent of treatment, and subjects having lower faecal Bacteroidetes exhibited increased concentrations of serum lipopolysaccharide and lipopolysaccharide binding protein independent of treatment. We found no evidence to support a defined health benefit for the use ofβ2-1 fructans in healthy subjects.
