Published: February 2021

This study describes the registration of the first cases of lumpy skin disease in July 2016 in the Republic of Kazakhstan. In the rural district of Makash, Kurmangazinsky district of Atyrau region, 459 cattle fell ill and 34 died (morbidity 12.9% and mortality 0.96%). To determine the cause of the disease, samples were taken from sick and dead animals, as well as from insects and ticks. LSDV DNA was detected by PCR in all samples from dead animals and ticks (Dermacentor marginatus and Hyalomma asiaticum), in 14.29% of samples from horseflies (Tabanus bromius), and in one of the samples from two Stomoxys calcitrans flies. The reproductive LSD virus was isolated from organs of dead cattle and insects in the culture of LT and MDBK cells. The virus accumulated in cell cultures of LT and MDBK at the level of the third passage with titers in the range of 5.5–5.75 log 10 TCID50/cm3. Sequencing of the GPCR gene allowed us to identify this virus as a lumpy skin disease virus.
Estimates of energy partitioning, evapotranspiration, and net ecosystem exchange of CO2 for an urban lawn and a tallgrass prairie in the Denver metropolitan area under contrasting conditions
Authors: Thienelt Thomas S. , Anderson Dean E.
Published: February 2021

Lawns as a landcover change substantially alter evapotranspiration, CO2, and energy exchanges and are of rising importance considering their spatial extent. We contrast eddy covariance (EC) flux measurements collected in the Denver, Colorado, USA metropolitan area in 2011 and 2012 over a lawn and a xeric tallgrass prairie. Close linkages between seasonal vegetation development, energy fluxes, and net ecosystem exchange (NEE) of CO2 were found. Irrigation of the lawn modified energy and CO2 fluxes and greatly contributed to differences observed between sites. Due to greater water inputs (precipitation + irrigation) at the lawn in this semi-arid climate, energy partitioning at the lawn was dominated by latent heat (LE) flux. As a result, evapotranspiration (ET) of the lawn was more than double that of tallgrass prairie (2011: 639(±17) mm vs. 302(±9) mm; 2012: 584(±15) mm vs. 265(±7) mm). NEE for the lawn was characterized by a longer growing season, higher daily net uptake of CO2, and growing season NEE that was also more than twice that of the prairie (2011: −173(±23) g C m−2 vs. -81(±10) g C m−2; 2012: −73(±22) g C m−2 vs. -21(±8) g C m−2). During the drought year (2012), temperature and water stress greatly influenced the direction and magnitude of CO2 flux at both sites. The results suggest that lawns in Denver can function as carbon sinks and conditionally contribute to the mitigation of carbon emissions - directly by CO2 uptake and indirectly through effects of evaporative cooling on microclimate and energy use.
Adsorption Capacity of Smectite Clay and Its Thermal and Chemical Modification for Two Anionic Dyes: Comparative Study
Authors: Pajak Magdalena
Published: February 2021

The present research evaluates the influence of modification of smectite clay (BC) on its adsorption capacity of anionic dyes from aqueous solutions. Thermal (BC 250), acidic (BC H2SO4), and alkaline (BC NaOH) modification of clay was carried out. The clays were characterized by X-ray powder diffraction, energy-dispersive X-ray spectroscopy, and Fourier transform infrared spectroscopy. Adsorption of dyes was investigated by batch experiments at room temperature (23 ± 2 °C), a wide range of initial dye concentrations (1–1000 mg/dm3), and an adsorbent dose of 50 g. All modifications increased the clay’s adsorption capacity for Reactive Red 198, in the order BC H2SO4> BC NaOH > BC 250 > BC; it was 10.32, 5.06, 3.32, and 2.92 mg/g, respectively. Acid and thermal modification of the clay increased its adsorption capacity for Acid Red 18, in the series BC H2SO4> BC 250 > BC > BC NaOH; it was 3.07, 2.66, 2.16, and 1.28 mg/g, respectively. The experimental data were analyzed by Freundlich, Langmuir, Dubinin–Radushkevich, and Sips isotherms, using nonlinear regression. The experimental data best fitted the Sips isotherm. Taking into account the structure of the adsorbent and adsorbates and the results obtained, it can be concluded that the dyes were probably bound through chemisorption, by forming hydrogen bonds between Si–OH and Al–OH groups in the clay and –NH, –NH2, and –OH groups in the dyes. From the results obtained, it can be concluded that smectite clay is a promising material for dye adsorption.
VideoOR: A Quality Oriented Replication Scheme for Video Opportunistic Transmission
Authors: Ma Huahong , Wu Honghai , Xing Ling , Xie Ping , Wang Dan
Published: February 2021

With the development of various mobile social applications, video data has already occupied a dominant proportion of mobile Internet traffic, and is still growing rapidly, which not only brings economic pressure to users, but also causes traffic explosion on Internet. Data delivery through mobile opportunistic networks is regarded as an efficient way to deal with this problem. But, due to the characteristics of video data and the mode of multi-copy routing, video opportunistic delivery will consume large amount of network resources, resulting in excessive transmission overhead and lower delivery quality. Fortunately, the strong aggregation of human activity gives us some inspiration, which can provide more space of deep optimization on video opportunistic transmission. Thus, in this paper, taking fully advantage of the connectivity of cluster formed by the gathering crowds, we propose a Video Opportunistic Replication scheme based on multi-player cooperative games, named VideoOR, which can achieve the double optimizations of transmission overhead and video delivery quality by scheduling the replication and forwarding of video packets under the guidance of Nash Equilibrium solution. Extensive simulations have been done based on the synthetic and real mobility traces, and the results show that our scheme can maximize the quality of reconstructed video and minimize the average replication times of each video packet.

This updated systematic review assesses the effects of pharmacological interventions for drug-using offenders.

Methods

Systematic review protocols and conventions of the Cochrane Collaboration were followed to identify eligible studies. Studies were pooled in a meta-analysis to assess the impact of pharmacological interventions on drug use and criminal activity. An economic appraisal was conducted.

Results

The search strategies identified 22 studies containing 4372 participants. Meta-analyses revealed a small statistically significant mean difference favouring pharmacological interventions relative to psychological interventions in reducing drug use and criminal activity. When comparing the drugs to one another there were no significant differences between those included (methadone versus buprenorphine, naltrexone and cyclazocine).

Conclusion

Overall, the findings of this review suggest that methadone and naltrexone may have some impact on reducing drug use and reincarceration. Individual pharmacological drugs had differing (generally non-significant) effects. One study identified serious adverse events. Three studies reported cost and consequences information sufficient to conduct a full economic analysis but this was not comprehensive enough to be able to make judgements across all treatment options. Full economic analyses should be encouraged. The study findings were limited mainly to male adult offenders.
Volume Fraction Measurement of Soft (Dairy) Microgels by Standard Addition and Static Light Scattering
Authors: Heck Anisa , Nöbel Stefan , Hitzmann Bernd , Hinrichs Jörg
Published: February 2021

The volume fraction of the dispersed phase in concentrated soft (dairy) microgels, such as fresh cheese, is directly related to structure and rheology. Measurement or modeling of volume fraction for soft and mechanically sensitive microgel dispersions is problematic, since responsiveness and rheological changes upon mechanical input for these systems limits application of typical functional relationships, i.e., using apparent viscosity. In this paper, we propose a method to measure volume fraction for soft (dairy) microgel dispersions by standard addition and volume-weighted particle size distributions obtained by static light scattering. Relative particle volumes are converted to soft particle volume fraction, based on spiked standard particle volumes. Volume fractions for two example microgel dispersions, namely, differently produced fresh cheeses, were evaluated before and after post-treatments of tempering and mechanical processing. By selecting the size of standard particles based on size ratios and the levels of the mixing ratios/relative fractions, the method could be applied robustly within a wide range of particle sizes (1 to 500 μm) and multimodal size distributions (up to quadmodal). Tempering increased the volume fraction for both example microgel dispersions (P < 0.05). Subsequent mechanical treatment reduced the volume fraction back to the starting value before tempering (P < 0.05). Furthermore, it was shown that the increase and successive decrease in apparent viscosity with tempering and mechanical post-treatments is not exclusively due to particle aggregation and breakdown, but to volume changes of each particle. For environmentally responsive soft matter, the proposed method is promising for measurement of volume fraction.
Criminal Blame, Exclusion and Moral Dialogue
Authors: Porro Costanza
Published: February 2021

In her recent book The Limits of Blame, Erin Kelly argues that we should rethink the nature of punishment because delivering blame is, contrary to the widely held view, not among the justifiable aims of a criminal justice system. In this paper, firstly, I discuss her case against criminal blame. Kelly argues that the emphasis on blame in the criminal justice system and in public discourse is one of the main causes of the stigma and exclusion faced by those convicted for a crime. This claim might appear puzzling and, while she provides other convincing arguments against criminal blame, Kelly does not extensively defend this particular argument. To offer support for this view, I reflect on the often overlooked distinction between moral blame and criminal blame to show how the latter, unlike the former, is exclusionary and stigmatising. Secondly, I address the claim put forth by Kelly that blame should play no role in the criminal justice system at all. In light of her argument about the optional nature of moral blame, I explore the possibility that the state should leave open to victims the option to blame criminal wrongdoers in restorative justice conferences. I argue that in such contexts blame would not have the same exclusionary features of criminal blame in traditional settings and that it could serve some valuable aims articulated by communicative theories of punishment, such as the restoration of moral relationships.
Personality traits, working conditions and health: an empirical analysis based on the German Linked Personnel Panel, 2013–2017
Authors: Bellmann Lutz , Hübler Olaf
Published: February 2021

We conduct a comprehensive analysis of health determinants at the individual and workplace levels. Using a new individual-level German data set, we investigate the influence of these determinants on health, including collegiality, personality traits as measured by the Big Five, commitment to the company and job characteristics, while controlling for a set of standard sociodemographic and employment variables. We are interested in which determinants are important and which are less influential, whether interaction effects should be taken into account and whether the results depend on the modeling and estimation method used. Among the Big Five factors, conscientiousness, agreeableness and emotional stability are positively correlated with good overall health. The influence of job characteristics such as having substantial decision-making authority, not having physically demanding tasks, having pleasant environmental conditions, facing minimal time pressure and not being required to multitask are also positive. If employees frequently receive help when needed from their colleagues and do not feel unfairly criticized by others in the firm, they usually have fewer health problems. Each Big Five item influences mental health, whereas no statistical significance could be found for these items’ relationships with the number of days workers were absent due to sickness, except for neuroticism. These results are, for the most part, robust to different modeling and estimation methods.
Single entity electrochemistry and the electron transfer kinetics of hydrazine oxidation
Authors: Miao Ruiyang , Shao Lidong , Compton Richard G.
Published: February 2021

The mechanism and kinetics of the electro-catalytic oxidation of hydrazine by graphene oxide platelets randomly decorated with palladium nanoparticles are deduced using single particle impact electrochemical measurements in buffered aqueous solutions across the pH range 2–11. Both hydrazine, N2H4, and protonated hydrazine N2H5+ are shown to be electroactive following Butler-Volmer kinetics, of which the relative contribution is strongly pH-dependent. The negligible interconversion between N2H4 and N2H5+ due to the sufficiently short timescale of the impact voltammetry, allows the analysis of the two electron transfer rates from impact signals thus reflecting the composition of the bulk solution at the pH in question. In this way the rate determining step in the oxidation of each specie is deduced to be a one electron step in which no protons are released and so likely corresponds to the initial formation of a very short-lived radical cation either in solution or adsorbed on the platelet. Overall the work establishes a generic method for the elucidation of the rate determining electron transfer in a multistep process free from any complexity imposed by preceding or following chemical reactions which occur on the timescale of conventional voltammetry.

Published: February 2021

Adiponectin (Acrp30) and leptin, adipokines produced and secreted mainly by the adipose tissue, are involved in human carcinogenesis. Thyroid carcinomas are frequent endocrine cancers, and several evidences suggest that they are correlated with obesity. In this study, we first analyzed the expression levels and prognostic values of Acrp30, leptin, and their receptors in thyroid cancer cells. Then, we investigated the role of Acrp30 and leptin in proliferation, migration, and invasion. We found that Acrp30 treatment alone inhibits cell proliferation and cell viability in a time and dose-dependent manner; leptin alone does not influence thyroid cancer cells (BCPAP and K1) proliferation, but the combined treatment reverts Acrp30-induced effects on cell proliferation. Additionally, through wound healing and Matrigel Matrix invasion assays, we unveiled that Acrp30 inhibits thyroid cancer cell motility, while leptin induces the opposite effect. Importantly, in the combined treatment, Acrp30 and leptin exert antagonizing effects on papillary thyroid cancer cells’ migration and invasion in both BCPAP and K1 cell lines. Highlights of these studies suggest that Acrp30 and leptin could represent therapeutic targets and biomarkers for the management of thyroid cancer.
A critical review of synthesis parameters affecting the properties of zinc oxide nanoparticle and its application in wastewater treatment
Authors: Shaba E. Y. , Jacob J. O. , Tijani J. O. , Suleiman M. A. T.
Published: February 2021

In this era, nanotechnology is gaining enormous popularity due to its ability to reduce metals, metalloids and metal oxides into their nanosize, which essentially alter their physical, chemical, and optical properties. Zinc oxide nanoparticle is one of the most important semiconductor metal oxides with diverse applications in the field of material science. However, several factors, such as pH of the reaction mixture, calcination temperature, reaction time, stirring speed, nature of capping agents, and concentration of metal precursors, greatly affect the properties of the zinc oxide nanoparticles and their applications. This review focuses on the influence of the synthesis parameters on the morphology, mineralogical phase, textural properties, microstructures, and size of the zinc oxide nanoparticles. In addition, the review also examined the application of zinc oxides as nanoadsorbent for the removal of heavy metals from wastewater.

Published: February 2021

Inclusively delivering the sustainable development goals (SDGs) remains challenging, particularly in urban areas, where some of the most pressing concerns exist. To achieve the transformative SDG agenda, new methods are required to overcome current deficits in engagement around inclusion and equitable outcomes. Evaluating against theories of governance and inclusion, we test a mixture of digital and physical creative methods abilities to deliver co-designed solutions that influence mobility and road safety planning outcomes in East African cities. Greater inclusion led to improved interactions of citizens with decision makers, and the identification of novel, practical solutions, delivering some elements of transformation. Risks include creative methods being used to co-opt communities to official agendas, and institutional planning norms needing to adapt to respond to a wider range of stakeholders. Overall, where risks are mitigated, we recommend that using Creative Methods could localise SDG delivery, ensuring more equitable and effective outcomes from infrastructure development investments.
Finite Element Method modeling of Additive Manufactured Compressor Wheel
Authors: Birosz Márton Tamás , Andó Mátyás , Jeganmohan Sudhanraj
Published: February 2021

Designing components is a complex task, which depends on the component function, the raw material, and the production technology. In the case of rotating parts with higher RPM, the creep and orientation are essential material properties. The PLA components made with the material extrusion process are more resistant than VeroWhite (material jetting) and behave similarly to weakly cross-linked elastomers. Also, based on the tensile tests, Young’s modulus shows minimal anisotropy. Multilinear isotropic hardening and modified time hardening models are used to create the finite element model. Based on the measurements, the finite element method simulation was identified. The deformation in the compressor wheel during rotation became definable. It was concluded that the strain of the compressor wheel manufactured with material extrusion technology is not significant.

Published: February 2021

In this paper, the Rayleigh beam system with two dynamical boundary controls is treated. Theoretically, the well-posedness of the weak solution is obtained. Later, we discretize the system by using the Implicit Euler scheme in time and the$$P^3$$P3Hermite finite element in space. In addition, we show the decay of the discrete energy and we establish some a priori error estimates. Finally, some numerical simulations are presented.
Predicting Response to Brain Stimulation in Depression: a Roadmap for Biomarker Discovery
Authors: Nord Camilla L.
Published: February 2021

Purpose of Review

Clinical response to brain stimulation treatments for depression is highly variable. A major challenge for the field is predicting an individual patient’s likelihood of response. This review synthesises recent developments in neural predictors of response to targeted brain stimulation in depression. It then proposes a framework to evaluate the clinical potential of putative ‘biomarkers’.

Recent Findings

Largely, developments in identifying putative predictors emerge from two approaches: data-driven, including machine learning algorithms applied to resting state or structural neuroimaging data, and theory-driven, including task-based neuroimaging. Theory-driven approaches can also yield mechanistic insight into the cognitive processes altered by the intervention.

A pragmatic framework for discovery and testing of biomarkers of brain stimulation response in depression is proposed, involving (1) identification of a cognitive-neural phenotype; (2) confirming its validity as putative biomarker, including out-of-sample replicability and within-subject reliability; (3) establishing the association between this phenotype and treatment response and/or its modifiability with particular brain stimulation interventions via an early-phase randomised controlled trial RCT; and (4) multi-site RCTs of one or more treatment types measuring the generalisability of the biomarker and confirming the superiority of biomarker-selected patients over randomly allocated groups.

Authors: Roller-Wirnsberger Regina , Lindner Sonja , Kolosovski Lea , Platzer Elisabeth , Dovjak Peter , Flick Holger , Tziraki Chariklia , Illario Maddalena
Published: February 2021

Background

Although the burden of influenza infection is the highest in older adults, vaccination coverage remains low, despite this age group being more vulnerable than others.

Aims

Given the current pandemic of SARS-CoV-2, it was the aim of this scope review to update knowledge on factors affecting seasonal influenza vaccine uptake among older adults to strengthen prevention approaches in the context of an overall burden of infectious diseases.

Methods

We searched bibliographic databases from 2012 to 2019. All studies reviewed one or more social determinant of health listed by WHO, or factors affecting the decision-making process whether to accept influenza vaccine or not.

Results

Overall, 44 studies were included, 41 determinants were extracted and summarized into six categories. Older age and constitutional factors including multiple chronic diseases as well as preventive lifestyle and frequent routine healthcare utilization positively affected vaccination uptake (VU). Living and working conditions are also researched determinants of influenza vaccine uptake. A small number of studies explored the role of social inclusion and system-based interventions.

Discussion and conclusions

This scope review provides a comprehensive overview on factors affecting seasonal influenza vaccination uptake among older citizens. The review also clearly shows gaps for evidence on system-based level or political strategies to improve vaccination uptake.
Experimental study on permanent deformation characteristics of coarse-grained soil under repeated dynamic loading
Authors: Mei Huihao , Satvati Sajjad , Leng Wuming
Published: February 2021

Practical assessment of subgrade settlement induced by train operation requires developing suitable models capable of describing permanent deformation characteristics of subgrade filling under repeated dynamic loading. In this paper, repeated load triaxial tests were performed on coarse-grained soil (CGS), and the axial permanent strain of CGS under different confining pressures and dynamic stress amplitudes was analysed. Permanent deformation behaviors of CGS were categorized based on the variation trend of permanent strain rate with accumulated permanent strain and the shakedown theory. A prediction model of permanent deformation considering stress state and number of load cycles was established, and the ranges of parameters for different types of dynamic behaviors were also divided. The results indicated that the variational trend of permanent strain rate with accumulated permanent strain can be used as a basis for classifying dynamic behaviors of CGS. The stress state (confining pressure and dynamic stress amplitude) has significant effects on the permanent strain rate. The accumulative characteristics of permanent deformation of CGS with the number of load cycles can be described by a power function, and the model parameters can reflect the influence of confining pressure and dynamic stress amplitude. The study’s results could help deepen understanding of the permanent deformation characteristics of CGS.

Purpose

Low free testosterone (T) level in men is independently associated with presence and severity of Non-Alcoholic Steatohepatitis (NASH). The histological and molecular effects of oral testosterone prodrug LPCN 1144 treatment on hepatic fibrosis and NASH features are unknown. A metabolic syndrome-induced NASH model in rabbits consuming high fat diet (HFD) has been previously used to assess treatment effects of injectable T on hepatic fibrosis and NASH features. Here we present results on LPCN 1144 in this HFD-induced, NASH preclinical model.

Methods

Male rabbits were randomly assigned to five groups: regular diet (RD), HFD, HFD + 1144 vehicle (HFD + Veh), HFD + 1144 (1144), and HFD + 1144 + α-tocopherol (1144 + ALPHA). Rabbits were sacrificed after 12 weeks for liver histological, biochemical and genetic analyses. Histological scores were obtained through Giemsa (inflammation), Masson’s trichrome (steatosis and ballooning), and Picrosirius Red (fibrosis) staining.

Results

Compared to RD, HFD and HFD + Veh significantly worsened NASH features and hepatic fibrosis. Considering HFD and HFD + Veh arms, histological and biomarker features were not significantly different. Both 1144 and 1144 + ALPHA arms improved mean histological scores of NASH as compared to HFD arm. Importantly, percentage of fibrosis was improved in both 1144 (p < 0.05) and 1144 + ALPHA (p = 0.05) treatment arms vs. HFD. Both treatment arms also reduced HFD-induced inflammation and fibrosis mRNA markers. Furthermore, 1144 treatments significantly improved HFD-induced metabolic dysfunctions.

Conclusions

Histological and biomarker analyses demonstrate that LPCN 1144 improved HFD-induced hepatic fibrosis and NASH biochemical, biomolecular and histochemical features. These preclinical findings support a therapeutic potential of LPCN 1144 in the treatment of NASH and of hepatic fibrosis.

Le malattie ipotalamiche e il loro trattamento chirurgico possono determinare un rapido incremento ponderale nei primi sei mesi, seguito da stabilizzazione del peso in un’elevata percentuale (40–80%) di pazienti. Gli interventi sullo stile di vita e i farmaci hanno fornito risultati insoddisfacenti. Maggiori benefici sono stati riportati con gli analoghi del glucagon like peptide-1 o con la chirurgia bariatrica ma gli studi ad oggi disponibili sono di bassa numerosità e di breve durata.
Is Wilson’s religion Durkheim’s, or Hobbes’s Leviathan?
Authors: Atkinson Andrew R.
Published: February 2021

This paper critically supports the modern evolutionary explanation of religion popularised by David Sloan Wilson, by comparing it with those of his predecessors, namely Emile Durkheim and Thomas Hobbes, and to some biological examples which seem analogous to religions as kinds of superorganisms in their own right. The aim of the paper is to draw out a theoretical pedigree in philosophy and sociology that is reflected down the lines of various other evolutionarily minded contributors on the subject of religion. The general theme is of evolved large-scale cooperative structures. A scholarly concern is as follows: Wilson (Darwin’s Cathedral: Evolution, Religion, And The Nature Of Society, University of Chicago Press, Chicago, 2002) draws on Durkheim, (The elementary forms of religious life. Free Press, New york, 1912) using Calvinism as an example without mentioning Hobbes (Leviathan, Edited by E. Curley, Cambridge, Hackett, 1651), but it was Thomas Hobbes (1588–1679) who used Calvinism as an example of a leviathanesque religious structure—which is not acknowledged by either Wilson or Durkheim. If there are even any similarities between these authors, there appears to be an omission somewhere which should rightly be accounted for by giving credit to Hobbes where it is due. I issue on conclusion, what it is that makes Wilson’s approach radically different to that it skates on. I also issue it with a cautionary word.
Mathematics in the Digital Age: The Case of Simulation-Based Proofs
Authors: Sümmermann Moritz Lucius , Sommerhoff Daniel , Rott Benjamin
Published: February 2021

Digital transformation has made possible the implementation of environments in which mathematics can be experienced in interplay with the computer. Examples are dynamic geometry environments or interactive computational environments, for exampleGeoGebraorJupyter Notebook, respectively. We argue that a new possibility to construct and experience proofs arises alongside this development, as it enables the construction of environments capable of not only showing predefined animations, but actually allowing user interaction with mathematical objects and in this way supporting the construction of proofs. We precisely define such environments and call them “mathematical simulations.” Following a theoretical dissection of possible user interaction with these mathematical simulations, we categorize them in relation to other environments supporting the construction of mathematical proofs along the dimensions of “interactivity” and “formality.” Furthermore, we give an analysis of the functions of proofs that can be satisfied by simulation-based proofs. Finally, we provide examples of simulation-based proofs inAriadne, a mathematical simulation for topology. The results of the analysis show that simulation-based proofs can in theory yield most functions of traditional symbolic proofs, showing promise for the consideration of simulation-based proofs as an alternative form of proof, as well as their use in this regard in education as well as in research. While a theoretical analysis can provide arguments for the possible functions of proof, they can fulfil their actual use and, in particular, their acceptance is of course subject to the sociomathematical norms of the respective communities and will be decided in the future.
Assessing Neuropsychological Functions in Middle Childhood: a Narrative Review of Measures and Their Psychometric Properties Across Context
Authors: Rachel Maina , Fons Van De Vijver J. R. , Amina Abubakar , Perez-Garcia Miguel , Manasi Kumar
Published: February 2021

Background

There is a significant number of neuropsychological measures for use among children aged 6–12 years. However, most of these tests have been developed in high-income contexts (HICs). To avoid or to at least to minimize bias in assessment, most researchers carry out cultural adaptations of these tools. In selecting sub-tests to adapt before using the entire test battery, researchers would benefit from having a reference source summarizing available tools and how easily they can be used in different context. This is where the paper makes a contribution. This narrative review has a twofold aim: first, to identify tools commonly used among 6–12-year-olds; second, to summarize the psychometric properties of these tools especially emphasizing their usage across different cultural contexts.

Methods

We searched the literature from 1 January 1987 to 31 December 2017 for tools used among children aged 6 to 12 years. An extensive search of PubMed, Psych Info and Web of Science using the keywords (i) neuropsychological or neurocognitive with (ii) assessment or test was done.

Results

A hundred and forty-five papers out of 306 reported on psychometric properties of different tools including Behavior Rating Inventory of Executive Functioning—BRIEF (count = 6), Visual-Motor Integration—VMI (count = 6), the Test of Memory Malingering—TOMM (count = 6), MSVT (count = 6) and Continuous Performance Tests—CPT (count = 6). Forty-six percent of the papers reported studies conducted in the USA. Most of these studies were based in high-income countries, which further highlights the need to validate these measures for use in lower- and middle-income countries. Psychometric check was adequate in most tests for measuring executive functioning such as BRIEF, although tests such as CPT that measure complex attention had mixed findings. Moreover, we found that these studies addressed certain aspects of validity and or reliability while leaving out others; thus, a comprehensive picture is lacking.

Conclusion

We propose further studies to thoroughly investigate and report the psychometric properties of these measures, especially in lower- and middle-income countries.
Late Miocene–Early Pliocene planktic foraminiferal biostratigraphy of deep offshore southwestern Niger Delta
Authors: Adebambo Bamidele Adeniyi , Fadiya Suyi Lawrence
Published: February 2021

The planktic foraminiferal biostratigraphy of the deep offshore southwestern Niger Delta has been studied from three wells (DPW-1, DPW-2 and DPW-3). A total of 418 ditch cutting samples (104 samples from DPW-1, 165 from DPW-2 and 149 from DPW-3) taken at 18-m intervals were subjected to standard micropaleontological processing techniques. In total, 42, 52 and 40 planktic foraminiferal species were identified from DPW-1, DPW-2 and DPW-3, respectively. The identified planktic species allow the delineation of the studied section into four biozones—Globorotalia acostaensis(N16),Globigerinoides obliquus extremus/Globorotalia merotumida(N17),Globorotalia margaritae primitiva(N18) andGloborotalia margaritae evoluta/Globigerina nepenthes(N19) zones, based on the first appearance datums (FADs), last appearance datums (LADs) of the nominate taxa and associated assemblages. The well sections dated Late Miocene to Early Pliocene based on the occurrence of certain diagnostic planktic foraminiferal datums such as FADsGloborotalia acostaensis,Globigerinoides obliquus extremus,Globorotalia merotumida/plesiotumida,Globorotalia margaritae primitivaand the LADsGlobigerina nepenthes, Globorotalia margaritae primitivaandGloborotalia margaritae evoluta. The Miocene/Pliocene boundary was placed at the FADGloborotalia margaritae primitiva.In the Niger Delta, this boundary is commonly placed at the FADsGloborotalia margaritae margaritaeandGloborotalia crassaformisprobably due to nonrecovery ofGloborotalia margaritae primitiva.However, in this studied section of the deep offshore southwestern Niger Delta, FADGloborotalia margaritae primitivaoccurs consistently in the three study wells and is therefore considered an appropriate datum for the placement of the Miocene/Pliocene boundary.
Simulation approach on turbulent thermal performance factor of Al2O3-Cu/water hybrid nanofluid in circular and non-circular ducts
Authors: Wong Ing Jiat Kendrick , Tiong Ngieng Tze Angnes
Published: February 2021

This paper presents the numerical study of thermal performance factor of Al2O3-Cu/water hybrid nanofluid in circular and non-circular ducts (square and rectangular). Turbulent regime is studied with the Reynolds number ranges from 10000 to 100000. The heat transfer performance and flow behaviour of hybrid nanofluid are investigated, considering the nanofluid volume concentration between 0.1 and 2%. The thermal performance factor of hybrid nanofluid is evaluated in terms of performance evaluation criteria (PEC). This present numerical results are successfully validated with the data from the literature. The results indicate that the heat transfer coefficient and Nusselt number of Al2O3-Cu/water hybrid nanofluid are higher than those of Al2O3/water nanofluid and pure water. However, this heat transfer enhancement is achieved at the expense of an increased pressure drop. The heat transfer coefficient of 2% hybrid nanofluid is approximately 58.6% larger than the value of pure water at the Reynolds number of 10000. For the same concentration and Reynolds number, the pressure drop of hybrid nanofluid is 4.79 times higher than the pressure drop of water. The heat transfer performance is the best in the circular pipe compared to the non-circular ducts, but its pressure drop increment is also the largest. The hybrid nanofluid helps to improve the problem of low heat transfer characteristic in the non-circular ducts. In overall, the hybrid nanofluid flow in circular and non-circular ducts are reported to possess better thermal performance factor than that of water. The maximum attainable PEC is obtained by 2% hybrid nanofluid in the square duct at the Reynolds Number of 60000. This study can help to determine which geometry is efficient for the heat transfer application of hybrid nanofluid.
A new graphical technique for acceleration analysis of four bar mechanisms using the instantaneous center of zero acceleration
Authors: Diab Nadim
Published: February 2021

In this work, a new graphical technique is furnished for acceleration analysis of four bar mechanisms through locating the instantaneous center of zero acceleration$$IC_{a}$$ICaof the coupler link. First, the paper observes the coupler’s$$IC_{a}$$ICalocus and then proceeds with a series of graphical constructions that eventually lead into locating the$$IC_{a}$$ICaand obtaining the linear/angular accelerations of the coupler and follower (or slider) links. Based on the proposed graphical technique, the ease of acceleration analysis for four-bar mechanisms with varying driver’s angular acceleration is demonstrated. Simultaneously, the inflection circle of the coupler curve is constructed without the need to apply Euler-Savary equations. With fewer constructions than classical graphical techniques, the robustness and simplicity of the proposed method are demonstrated by performing acceleration analysis of a slider-crank (RRRP) and a planar quadrilateral linkage (RRRR).

High Static Low Dynamic Stiffness (HSLDS) is a kind of nonlinear visco-elastic device with features of passive control systems. This device presents the main advantages of working without a need for external energy and a maintenance of low cost. Thus, the paper deals with effects of HSLDS-outriggers at a predefined location on a high rise building subjected under earthquake excitation. The partial derivative equations based on the Timoshenko theory are used to model the tall building as an elastic-continuum beam. The nonstationary random approach is used to illustrate the dynamics of earthquake excitation of repeated sequences. Known as the powerful analytical tool and currently applicable to a variety of stochastic and deterministic problems, the stochastic averaging generalized by harmonic function is developed to linearize the modal equation of the structural system. It is showed that the direct simulation is good agreement with equivalent linearization technique. In doing so, it appears that this approximate analytical technique is very convenient to quantify the threshold values of parameters of the HSLDS control device. The obtained results come out that the control device significantly improved the seismic performance of the structural system at an acceptable level.
The digital revolution and digitalized network society
Authors: Knell Mark
Published: February 2021

This lecture discusses technological revolutions and techno-economic paradigms, but with an emphasis on the digital revolution and the digitalization of the economic and society. It draws its inspiration from works of Joseph Schumpeter, Christopher Freeman, and Carlota Perez on long waves of technological development and places the story within the context of global innovation networks. The lecture contends that the digital revolution not only transformed the world we live in but also created new ways to organize networks within it. We are now in second half of the digital (fifth technological) revolution, when the digitalization of the global networked economy prevails, and not at the beginning of Industrie 4.0. On the contrary, this is the period when economic growth drives the use of innovative digital technologies, including ubiquitous computing, robotics, and artificial intelligence, toward a truly digitalized network society.
Identification of changes in mechanical properties of sandstone subjected to high temperature: meso-and micro-scale testing and analysis

Published: February 2021

Material properties largely depend on their structure, and are strongly dependent on the scale of observation. Under the influence of various processes, the structure of a material can undergo evolution, which leads to major changes in the mechanical parameters and morphology of the medium. To understand the behaviour of a given material exposed to the influence of various factors, e.g. loading and temperature treatment, and to be able to modify it appropriately, it is crucial to recognize its structure both in the scale of engineering applications and at the micro-scale. The article proposes a procedure for assessing changes in the structure of sandstone exposed to the temperature treatment. The presented procedure allows the morphology of the material to be evaluated and the influence of temperature treatment on mechanical parameters of rocks to be analysed, by combining use of different laboratory techniques. The changes in rock material have been characterized using three investigative techniques, i.e. a uniaxial compression test, nanoindentation and micro-computed tomography. The uniaxial compression tests were carried out for 11 different temperature values in the range of 23–1000 °C, which enabled the determination of the change in uniaxial compressive strength and Young’s modulus of the sandstone as a function of temperature. Micro-scale laboratory tests were utilised to identify changes in the mechanical and morphological parameters of the sandstone exposed to the temperature of 1000 °C. The results were referred to those obtained for the reference samples, i.e. not subjected to heating (T = 23 °C). Comparison of the results showed an evident relation between the microstructure changes and the mesoscopic properties.
COVID-19 and the ethnicity link – is there a photochemical link?
Authors: Edge Ruth , Truscott T. George
Published: February 2021

A hypothesis is proposed to explain the increased detrimental effect of COVID-19 for Black, Asian and Minority Ethnic (BAME) men and women compared to Caucasian individuals. This is based on the differing photochemistry of phaeomelanin in fair skin and eumelanin in dark/black skin. It is suggested that a range of reactive oxygen species, including, singlet oxygen and the superoxide radical anion, derived via direct photolysis of phaeomelanin, may escape the melanocyte and cause subsequent damage to the SARS-CoV-2 virus. It is further suggested that (large) carbon and sulphur peroxy radicals, from oxygen addition to radicals formed by carbon–sulphur bond cleavage, may assist via damage to the cell membranes. It is also speculated that light absorption by phaeomelanin and the subsequent C-S bond cleavage, leads to release of pre-absorbed reactive oxygen species, such as singlet oxygen and free radicals, which may also contribute to an enhanced protective effect for fair-skinned people.
Reconstructing the Corporation

Published: February 2021

Modern corporations contribute to a wide range of contemporary problems, including income inequality, global warming, and the influence of money in politics. Their relentless pursuit of profits, though, is the natural outcome of the doctrine of shareholder primacy. As the consensus around this doctrine crumbles, it has become increasingly clear that the prerogatives of corporate governance have been improperly limited to shareholders. It is time to examine shareholder primacy and its attendant governance features anew, and reorient the literature around the basic purpose of corporations. This book critically examines the current state of corporate governance law and provides decisive rebuttals to longstanding arguments for the exclusive shareholder franchise. Reconstructing the Corporation presents a new model of corporate governance - one that builds on the theory of the firm as well as a novel theory of democratic participation - to support the extension of the corporate franchise to employees.
Interrelated Factors for Return to Work of Sick-Listed Employees in Sweden
Authors: Selander John , Sun Jing , Tjulin Asa , Buys Nicholas
Published: February 2021

Purpose:

Long-term sickness absence is a significant human and economic cost in many countries, including Sweden making research on factors which impact on return to work (RTW) relevant. This study has two aims: (1) provide an overview of factors that impact RTW expectations in a national sample of Swedish workers on long-term sickness absence; and (2) gain an understanding of the interrelationships among these factors using a socioecological framework and decision tree analysis.

Method:

A survey, designed to capture information about demographic variables, health and work ability, workplace contact, supervisor support and expectations of return to work, was mailed to 1,112 randomly selected sick-listed people in Sweden and completed by 534, representing a response rate of 48%.

Results:

The most important factors affecting RTW expectations were work ability and burnout. Employees reporting high levels of work ability were more likely to expect to RTW compared to those reporting low levels, and this was dependent on their relative burnout score. Those with a high burnout score were less likely to expect to RTW, while for those with a low burnout score RTW expectations were dependent on age, country of birth, and supervisor support. For young employees reporting low work ability and low burnout score, RTW expectations were lower.

Conclusions:

Our results suggest a more nuanced approach to delivery of RTW services is required, whereby practitioners need to understand the socioecology of the range of factors that impact RTW expectations. The use of decision tree analysis facilitates this understanding by describing the interrelationships between these factors.
