Authors: Nguyen Tan Dai , Tran Van‐Thai , Du Hejun 
Published: March 2021

AbstractReconstructing of cell architecture plays a vital role in tissue engineering. Recent developments of self‐assembling of cells into three‐dimensional (3D) matrix pattern using surface acoustic waves have paved a way for a better tissue engineering platform thanks to its unique properties such as nature of noninvasive and noncontact, high biocompatibility, low‐power consumption, automation capability, and fast actuation. This article discloses a method to manipulate the orientation and curvature of 3D matrix pattern by redesigning the top wall of microfluidic chamber and the technique to create a 3D longitudinal pattern along preinserted polydimethylsiloxane (PDMS) rods. Experimental results showed a good agreement with model predictions. This research can actively contribute to the development of better organs‐on‐chips platforms with capability of controlling cell architecture and density. Meanwhile, the 3D longitudinal pattern is suitable for self‐assembling of microvasculatures.
New horizons in reconstructing past human behavior: Introducing the “Tübingen University Validated Entheses‐based Reconstruction of Activity” method
Authors: Karakostis Fotios Alexandros , Harvati Katerina 
Published: March 2021

AbstractAn accurate reconstruction of habitual activities in past populations and extinct hominin species is a paramount goal of paleoanthropological research, as it can elucidate the evolution of human behavior and the relationship between culture and biology. Variation in muscle attachment (entheseal) morphology has been considered an indicator of habitual activity, and many attempts have been made to use it for this purpose. However, its interpretation remains equivocal due to methodological shortcomings and a paucity of supportive experimental data. Through a series of studies, we have introduced a novel and precise methodology that focuses on reconstructing muscle synergies based on three‐dimensional and multivariate analyses among entheses. This approach was validated using uniquely documented anthropological samples, experimental animal studies, histological observations, and geometric morphometrics. Here, we detail, synthesize, and critically discuss the findings of these studies, which overall point to the great potential of entheses in elucidating aspects of past human behavior.

AbstractTo assist the development of new therapeutic strategies for several disorders, biologically active peptides/proteins obtained from plant sources can be considered. Current study expected to determine the biological activities of peptide fractions of Mucuna pruriens against hepatocellular carcinoma cell lines (HepG2/ADM, HepG2, SMMC‐7721, and QGY‐7703), as well as normal cell line to prove their selectivity. Moreover, anti‐genotoxicity and antiviral activity against the hepatitis C virus (HCV) were assessed. The methods of this study were to isolate the peptides of M. pruriens and hydrolysate fractionation via fractionated pepsin‐pancreatin hydrolysates by ultrafiltration/high‐performance ultrafiltration cell, identify anti‐hepatoma activity of peptide fractions human liver cancer and normal cells by (3‐(4,5‐dimethylthiazole‐2‐yl)‐2,5‐biphenyl tetrazolium bromide) (MTT) assay, determine anti‐HCV, and assess anti‐genotoxic effect of peptide fractions against damage that induced via alkylating agent methyl methanesulphonate in human mononuclear cells. The results showed that the fraction 5–10 kDa has been reported to exhibit significant cytotoxic activity against HepG2 and QGY‐7703. It was proven that both of 5–10 and >10 kDa fractions are active against HCV. The cytotoxic concentration (CC50) of 5–10 kDa against the cell line was 703.04 ± 5.21 µg/ml. Anti‐genotoxic activities of the peptide fractions were evaluated as mean values for the analyzed comet images. In this regard, the highest activity of protecting DNA damages was observed by the peptide fraction of 5–10 kDa. This study revealed the potential ability of peptide fractions of M. pruriens for the treatment of liver cancer, HCV, and high activities of protecting DNA damages.

Published: March 2021

AbstractThe three‐dimensional (3D) printing properties of pure shrimp surimi are poor and require improvement via the addition of other materials. The effects of the different amounts of potato starch, corn starch, tapioca starch, and cross‐linked starch (CLS) (0%, 3%, 6%, or 9%, respectively) on the 3D printing properties and material properties of white shrimp (Litopenaeus vannamei) surimi were evaluated in the present study. The results showed that the apparent viscosity, G′, and G'' of the samples were increased by adding 6% CLS, making it easy to extrude the sample from the nozzle and resulting in an improvement in the printing accuracy. In addition, after adding 6% CLS, the hardness, adhesiveness, and springiness of the sample were increased, which assist with maintaining the shape of the printed material and improve the printing stability of the sample. Moreover, the water holding capacity of shrimp surimi increased as a result of the addition of 6% CLS. In summary, 6% CLS can improve the material properties of shrimp surimi and make it more suitable for 3D printing.
Reproductive health in an inpatient psychiatric unit: A retrospective chart review
Authors: Goldstein Naomi , Davis Caitlin , Saliba Zeina 
Published: March 2021

AbstractObjectiveThe purpose of this study was to evaluate the degree to which reproductive health issues are discussed with women of child‐bearing age on an inpatient psychiatric unit. We hypothesized that preconception care is limited, and that contraceptive status of patients is rarely elicited. For this sub‐analysis, we focused on counseling related to potential impacts of psychotropic medications on pregnancy, and on contraceptive status, especially when prescribed teratogenic medications.MethodsA retrospective search was conducted for women between the ages of 18 to 49 years at the time of admission, over a 6‐month period. One hundred and forty‐eight unique encounters were identified, and electronic charts were reviewed for information regarding: discharge medications, medication counseling, contraceptive use, pregnancy and relationship status, pregnancy history, nature of obstetrics and gynecology consults, substance use, and diagnoses.ResultsAlmost a fifth (n = 29) of encounters included discharge on at least one potentially teratogenic medication and more than 50% had recent substance use. However, less than 10% of all encounters had documentation of contraceptive status and only one case had documented discussion of reproductive effects of medication; this despite the fact that roughly one third (33.8%) had at least one documented prior pregnancy and two patients were pregnant at the time of admission.ConclusionFew women of reproductive age admitted to the inpatient psychiatric unit had chart‐documented counseling on reproductive health, including known side effects of teratogenic medications. This indicates an urgent need for inclusion of reproductive health, including counseling on the risks and benefits of taking psychotropics during the peripartum period, into inpatient mental health care.
Financial inclusion: A pathway to economic growth in Sub‐Saharan African economies
Authors: Adedokun Muri Wole , Ağa Mehmet 
Published: March 2021

AbstractThis study empirically assesses the relationship between financial inclusion and economic growth in Sub‐Saharan African (SSA) countries for the period of 2004–2017, using the generalized method of moments and Dumitrescu–Hurlin's causality test. Based on the multidimensionality of the financial inclusion measures, a principal component analysis was applied to develop a composite index for financial inclusion. The results show that financial inclusion has a significant positive influence on economic growth in SSA countries. Other findings indicate that there is causality running from economic growth to financial inclusion in the short run. Therefore, policymakers should emphasize strategies that foster access to quality and affordable financial services and products, to improve inclusive growth in the continent.
Fusing dual‐tree quaternion wavelet transform and local mesh based features for grading of diabetic retinopathy using extreme learning machine classifier
Authors: Deepa V. , Kumar C. Sathish , Andrews Sheena Susan 
Published: March 2021

AbstractDiabetic retinopathy (DR) is one of the most frequent microvascular complications of diabetes mellitus, which damages micro‐ and macrovascular systems. Hence, early detection and grading are important for its effective treatment. This study presents a comprehensive micro‐macro feature extraction algorithm for the grading of DR using retinal images. The method employed is a mutliresolutional microtechnique, based on dual‐tree quaternion wavelet transform fused with local mesh patterns. Since the pixel level model is unable to capture macrolevel features and is difficult for efficient decision‐making, this process additionally proposes a macrolevel feature extraction technique based on feature gradients. The macrolevel descriptor considers a group of pixels to find feature gradients of macrolevel lesions. Feature extracted using the micro‐macro approaches is summarized, and a comparison study using three machine learning classifiers is considered. Performance of the classifiers is determined by conducting a 10‐fold cross‐validation procedure. Among the classifiers, the highest classification accuracy of 93.2% is exhibited by radial basis function kernel extreme learning machine. Simulation results illustrate the adaptability and competency of the novel micro‐macro approach with high accuracy and sensitivity. The promising result assures the excellence of the proposed method for automated DR grading over other state‐of‐the‐art techniques.

Published: March 2021

AbstractThe use of hybrid turf systems is very common in Europe and is increasing in popularity in the United States. Little research was found on the impact of stitched hybrid systems on hybrid bermudagrass ‘NorthBridge’ (Cynodon dactylon(L.) Pers. ×C. TransvaalensisBurtt Davy) athletic fields. A study was conducted to determine the impact of stitched hybrid systems on hybrid bermudagrass performance at the University of Tennessee Center for Athletic Field Safety in Knoxville, TN USA in the fall of 2018 and 2019. A randomized complete block design with four replications was utilized. The study treatments consisted of synthetic fibers spacing stitched in 2 cm by 2 cm, 2 cm by 4 cm treatments, and an untreated control. Each plot received 30 games of simulated traffic events with 12 test variables collected including: percent green cover, surface hardness, head impact criteria, ball rebound, ball roll, angled ball rebound, vertical deformation, energy restitution, force reduction, surface temperature, and rotational and horizontal traction. Results indicated that the only differences among stitched treatments were in rotational traction with the 2 cm by 2 cm treatment having the highest values, increasing the traction for athletic movements. Traffic had a significant effect on green cover, surface hardness, head injury criterion, ball rebound, force reduction, energy restitution, and vertical deformation, regardless of treatment. These findings suggest that the stitched fiber system did not significantly impact hybrid bermudagrass athletic field performance.
Care as a Border‐Crossing Language: The Webtoon Reader Discussion Forum as Mediascape
Authors: Jeon Ahrum 
Published: March 2021

AbstractDrawing from Appadurai’s notion of mediascape, in which global cultural flows simultaneously construct local/global perspectives, I explored how youth and young adults across the globe make sense of digitally shared space, with a specific focus on the Webtoon reader discussion forum. Findings illustrated that the participants constructed the notion of care as standing up for others, raised awareness of social justice, and mobilized transcultural values to construct a cross‐cultural community with multimodal engagements. By understanding the reader discussion forum as a mutually constitutive negotiated space, the voluntary decision of these young individuals to engage in Korean Webtoon digital space underscores how they construct literacy practices across the globe while transcending demarcated categories of race, gender, language, culture, and other essentialized identity markers.
Comparison of many‐particle representations for selected‐CI I: A tree based approach
Authors: Chilkuri Vijay Gopal , Neese Frank 
Published: March 2021

AbstractThe full configuration interaction (FCI) method is only applicable to small molecules with few electrons in moderate size basis sets. One of the main alternatives to obtain approximate FCI energies for bigger molecules and larger basis sets is selected CI. However, due to: (a) the lack of a well‐defined structure in a selected CI Hamiltonian, (b) the potentially large number of electrons together with c) potentially large orbital spaces, a computationally and memory efficient algorithm is difficult to construct. In the present series of papers, we describe our attempts to address these issues by exploring tree‐based approaches. At the same time, we devote special attention to the issue of obtaining eigenfunctions of the total spin squared operator since this is of particular importance in tackling magnetic properties of complex open shell systems. Dedicated algorithms are designed to tackle the CI problem in terms of determinant, configuration (CFG) and configuration state function many‐particle bases by effective use of the tree representation. In this paper we describe the underlying logic of our algorithm design and discuss the advantages and disadvantages of the different many particle bases. We demonstrate by the use of small examples how the use of the tree simplifies many key algorithms required for the design of an efficient selected CI program. Our selected CI algorithm, called the iterative configuration expansion, is presented in the penultimate part. Finally, we discuss the limitations and scaling characteristics of the present approach.
Job crafting towards strengths and job crafting towards interests in overqualified employees: Different outcomes and boundary effects
Authors: Zhang Fangfang , Wang Bin , Qian Jing , Parker Sharon K. 
Published: March 2021

SummaryIn response to the call to investigate the positive side of overqualification, we drew on the job crafting perspective to theorize that overqualified employees can proactively regulate the discrepancies between their actual and ideal jobs via two different job crafting strategies: job crafting towards strengths (JC‐strengths) and job crafting towards interests (JC‐interests). We expected distinct positive outcomes for JC‐strengths and JC‐interests. Specifically, JC‐strengths benefits both overqualified employees and the organization, whereas JC‐interests only benefits the individual employees. We further proposed that the relationship between perceived overqualification and JC‐strengths will be stronger when employees' organizational identification is higher, whereas the relationship between perceived overqualification and JC‐interests will be stronger when their identification with the organization is lower. As expected, with the use of two‐wave and dual‐source data from 653 employees, we found that perceived overqualification was positively related to both JC‐strengths and JC‐interests; JC‐strengths was positively related to both vitality and supervisor‐rated task performance, whereas JC‐interests was only positively related to vitality. We also found that the relationship between perceived overqualification and JC‐strengths was moderated by organizational identification as hypothesized.

AbstractTranscranial random noise stimulation (tRNS) increases performance in some perceptual tasks. However, little is known about its effect on creativity. Although dorsolateral prefrontal cortex (DLPFC) has been postulated as an important cortical area related to creativity, the relative role of left and right DLPFC is still unclear. We aimed to compare the effect of anodal left/cathodal right (L + R−) and cathodal left/anodal right (L − R+) tRNS over the DLPFC. Eighty‐four participants were randomly assigned to L + R−, L−R+ or sham group. Current was set at 2 mA (100–500 Hz) with a 1 mA direct current offset (20 min). Creativity was assessed before and during tRNS with the Remotes Associates Test (RAT), Unusual Uses (UU) and Picture Completion (PC) from Torrance Test of Creative Thinking, nine‐dot problem and matchstick arithmetic problems. Bootstrapped analysis of covariance (under‐stimulation scores controlling for baseline) showed that L + R− and L − R+ groups had higher scores than sham in UU whereas only L + R− improved in RAT compared to sham. The L − R+ group performed significantly better than L + R− and sham groups in PC, nine‐dot problem and matchstick arithmetic problems. L + R− DLPFC may help verbal creative thinking whereas the L − R + seems to produce a “releasing effect” through insight problem solving and originality.
What warrants our claims? A methodological evaluation of argument structure
Authors: Ketokivi Mikko , Mantere Saku 
Published: March 2021

AbstractThe process of justifying a generalized theoretical conclusion from a specific empirical analysis continues to elude us. In this article, we suggest that this stems from an incomplete understanding and specification of how arguments are structured. Most importantly, in addition to empirical data, a generalized conclusion hinges on the application of various rules and principles of reasoning that British philosopher Stephen Toulmin labeled warrants. In this article, we apply Toulmin's model of argument structure to empirical management research by examining in particular the roles of four types of warrants: theoretical, inferential, procedural, and contextual. Based on our analysis, we suggest that making warrants and their backings explicit paves the way toward a more comprehensive understanding of how arguments are structured and how claims are justified. Importantly, an examination of warrants reveals that the choices researchers make are not limited to matters such as choosing the research topic or a particular research design, but they also extend to how we produce our claims. If we wish to understand argument structure, we must understand these choices.
Tribological Properties between Taut Hair Fibers in Wet Conditions: A New Shampoo Formulation for Eliminating Stick‐Slip Friction

Published: March 2021

AbstractThe tribological properties between taut hair fibers in wet conditions were investigated to evaluate the tangling/detangling performance of shampoo formulations during washing (particularly rinsing). A new setup for friction measurements between taut hair fibers was established. Using the setup, tribological properties of hair fibers treated with two shampoo formulations, whose tangling performances were different, were investigated. The base formulation for the shampoos was the same; the only difference was the type of amino‐modified silicones used as conditioning agents. Shampoo (Sp) A (poor detangling performance) incudes water‐insoluble silicone, and Sp B (excellent detangling performance) includes water‐soluble silicone. The tribological behaviors between taut hair fibers treated with the diluted solutions of the Sp were very different; the Sp A‐treated hair exhibited stick‐slip sliding, whereas the Sp B‐treated hair exhibited smooth sliding. This difference presumably comes from the different coacervation behaviors in the diluted solutions and resulting structure of conditioning film formed on hair surfaces. The smooth sliding (ideal for detangling) of Sp B‐treated hair comes from the two‐layer structure of the conditioning film on hair; positively charged amino‐modified silicone dissolved in water adsorbed immediately on negatively charged hair surface, followed by the physical adsorption of coacervates on the adsorbed silicone layer. The outer coacervate layer is easily removed during sliding, and smooth sliding comes from the low friction of the silicone layer. The relationship between the type of amino‐modified silicones, conditioning film formation on the surface, and tribological properties was discussed, which gives insights into designing Sp formulations with excellent detangling performance.

Published: March 2021

AbstractA novel series of cleavable alkyltrimethylammonium surfactants with different hydrocarbon chain lengths (C8–16) were synthesized. A carbonate break site inserted between the polar head and the hydrocarbon chain makes these compounds hydrolyzable. The reagents used are renewable, (bio)degradable, or reusable. The hydrolysis of these cleavable surfactants will lead to the generation of fatty alcohols and choline, which is an essential biological nutrient. The surface activities in aqueous solution of the synthesized carbonates fulfill the requirement of being good surfactants. In addition, the cleavable compounds containing n‐decyl and n‐dodecyl chains showed similar or higher antimicrobial activities when compared to a non‐cleavable analog.
