Horizontal Collectivism Moderates the Relationship Between in-the-Moment Social Connections and Well-Being Among Latino/a College Students
Authors: Hussain Maryam , Kho Carmen , Main Alexandra , Zawadzki Matthew J. 
Published: January 2021

AbstractSleep problems and poorer well-being may be particularly salient for Latino/a college students as they tend to experience sociocultural adjustments during this transitory time. Social connections, a correlate of health, change moment-to-moment for college students and may be experienced differently for people who more strongly endorse horizontal collectivist cultural values. We used ecological momentary assessment (EMA) to examine how in-the-moment social connections influence in-the-moment health, and how horizontal collectivism moderates the moment-to-moment associations. Self-identified Latino/a college students (n = 221) completed a demographic information and cultural values questionnaire and then responded to EMA measures on their social connections, affective and subjective well-being, and sleep for 14 consecutive days. Better in-the-moment social connections associated with better health. Horizontal collectivism moderated some, but not all associations between social connections and health. Social connections are multidimensional and differently predict in-the-moment health among Latino/a college students who more strongly endorse horizontal collectivistic values. We discuss implications for identifying vulnerable well-being moments among this understudied population.

Published: January 2021

Abstract
Context
Landscape ecology as an interdisciplinary science has great potential to inform landscape planning, an integrated, collaborative practice on a regional scale. It is commonly assumed that landscape ecological concepts play a key role in this quest.

Objectives
The aim of the paper is to identify landscape ecological concepts that are currently receiving attention in the scientific literature, analyze the prevalence of these concepts and understand how these concepts can inform the steps of the planning processes, from goal establishment to monitoring.

Methods
We analyzed all empirical and overview papers that have been published in four key academic journals in the field of landscape ecology and landscape planning in the years 2015–2019 (n = 1918). Title, abstract and keywords of all papers were read in order to identify landscape ecological concepts. A keyword search was applied to identify the use of these and previously mentioned concepts in common steps of the planning cycle.

Results
The concepts Structure, Function, Change, Scale, Landscape as human experience, Land use, Landscape and ecosystem services, Green infrastructure, and Landscape resilience were prominently represented in the analyzed literature. Landscape ecological concepts were most often mentioned in context of the landscape analysis steps and least in context of goal establishment and monitoring.

Conclusions
The current literature spots landscape ecological concepts with great potential to support landscape planning. However, future studies need to address directly how these concepts can inform all steps in the planning process.

Abstract
Purpose
Acute ischemic stroke (AIS) due to tandem lesions (TLs) of extracranial Internal Carotid Artery and Anterior Cerebral Circulation are challenging for endovascular treatment (EVT). This study aims to evaluate feasibility, safety and efficacy of EVT for TLs’ AIS, with or without emergent carotid artery stenting (eCAS), in a real-life scenario.

Methods
Retrospective review of prospectively collected non-randomized thrombectomy databases from five stroke centers between 2015 and 2019. Consecutive patients with TLs’ AIS were selected. Clinical, neuroimage and procedure features, as well as antiplatelet therapy regimen, were evaluated. Primary outcome was 90-day mRS ≤ 2. Secondary outcomes included: mTICI score 2b-3, extracranial recanalization, procedural complications, symptomatic intracerebral hemorrhage (SICH) and 90-day mortality.

Results
Two hundred twenty-seven patients were enrolled (67.8% males; mean age 65.9 ± 12.9 years). We obtained mTICI 2b-3 in 77.1%, extracranial recanalization in 86.8%, 90-day mRS (available in 201/227 cases) ≤ 2 in 49.8%. Procedural complications occurred in 16.7%, SICH in 9.7%; 90-day mortality rate (available in 201/227 cases) was 14.4%. The strongest predictors of good clinical outcome were young age (p < 0.0001), low baseline NIHSS (p = 0.008), high baseline ASPECTS (p < 0.0001), good collateral flow (p = 0.013) and extracranial recanalization (p = 0.001). The most significant predictors of SICH were low baseline ASPECTS (p < 0.0001), occurrence of complications (p < 0.0001) and eCAS (p = 0.002).

Conclusion
In our real-life series, the EVT for TLs’ AIS was feasible, safe and effective in improving 90-day functional outcome with acceptable morbi-mortality rates. ECAS increased the risk of SICH, independently from the antiplatelet therapy regimen.

Cancer prehabilitation—a short review
Authors: Crevenna Richard , Palma Stefano , Licht Thomas 
Published: January 2021

SummaryCancer prehabilitation uses the pretreatment time period to prevent a treatment-related functional decline and its subsequent consequences, and therefore occurs between the time of cancer diagnosis and the beginning of acute cancer treatment. This intervention has been shown to improve functional status, physical and psychological health outcomes and decrease overall health care costs. Currently there are several unimodal and one multimodal cancer prehabilitation regimens. Unimodal cancer prehabilitation includes exercise only, and multimodal cancer prehabilitation regimens are combinations of different interventions such as exercise, patient information and education, nutrition, psychologic counseling such as psycho-oncology, smoking cessation and reduction of alcohol consumption. Both approaches have the goal to improve physical capacity and mental health and to enable cancer patients to cope with the upcoming stress of the specific cancer-related treatment they need. Furthermore, cancer prehabilitation can support cancer patients to better participate in cancer rehabilitation after cancer treatment and maintain their ability to engage in premorbid activities. A growing body of scientific evidence confirms the importance of cancer prehabilitation. Further research is needed to study effectiveness and efficiency as well as clinical aspects of unimodal and multimodal cancer prehabilitation interventions.
Risikoberichterstattung in der deutschen Versicherungswirtschaft: Eine empirische Untersuchung von Konzernlageberichten
Authors: Dobler Michael , Schwartze Felix 
Published: January 2021

ZusammenfassungDieser Beitrag untersucht erstmals empirisch die Ausgestaltung und die Determinanten der Risikoberichterstattung von deutschen Versicherungsunternehmen in den obligatorischen Konzernlageberichten nach dem Deutschen Rechnungslegungs Standard Nr. 20 (DRS 20) „Konzernlagebericht“ hinsichtlich ihres Umfangs und ihrer Güte. Die Risikoberichterstattungspraxis erweist sich als heterogen und bleibt trotz beträchtlichem Umfang oft hinter den von DRS 20 vorgesehenen Angaben zurück. Über einen üblichen Size-Effekt hinaus scheinen Umfang und Güte der Risikoberichterstattung von diversen unternehmensspezifischen Einflussfaktoren geprägt zu sein. Wie branchenunabhängig von Dobler (2008) postuliert, erweist sich die Risikoberichterstattungspraxis deutscher Versicherungsunternehmen, trotz ausgeprägter Regulierung, von Publizitätsanreizen getrieben. Die Befunde bergen Implikationen für die Praxis, Regulierung und Forschung im Feld der branchenspezifischen Risikoberichterstattung.
A Probabilistic Fatigue Framework to Enable Location-Specific Lifing for Critical Thermo-mechanical Engineering Applications
Authors: Bandyopadhyay Ritwik , Sangid Michael D. 
Published: January 2021

AbstractThe present paper describes a probabilistic framework to predict the fatigue life and failure mode under various thermo-mechanical loading conditions. Specifically, inclusion- and matrix-driven competing failure modes are examined within nickel-based superalloys. The critical accumulated plastic strain energy density (APSED) is employed as a unified metric to predict fatigue crack initiation in metals, which is favorable due to the usage of a single unknown parameter and its capability to predict failure across loading conditions and failure modes. In this research, we characterize the temperature-dependent variation of the critical APSED using a Bayesian inference framework and predict the competing failure modes in a coarse grain variant of RR1000 with varying strain range and temperature. The critical APSED appears to decrease along a vertically reflected sigmoidal curve with increasing temperature. Further, (a) the prediction of a failure mode, (b) failure mode associated with the minimum life, and (c) the change in the location associated with the matrix-driven failure mode with increasing temperature and decreasing strain range are consistent with the experimentally observed trends in RR1000, as well as other Nickel-based superalloys, documented in the literature. Finally, for each simulated loading condition, the uncertainty in the fatigue life is quantified as a prediction interval computed based on a$$95\%$$95%confidence level of the critical APSED and the computed APSED from simulations. The overall framework provides a promising step towards microstructural-based fatigue life determination of components and enables a location-specific lifing approach.

Authors: Yang Fengwei , Gu Sai 
Published: January 2021

AbstractSince 2011, when the concepts of Industry 4.0 were first announced, this industrial revolution has grown and expanded from some theoretical concepts to real-world applications. Its practicalities can be found in many fields and affect nearly all of us in so many ways. While we are adapting to new changes, adjustments are starting to reveal on national and international levels. It is becoming clear that it is not just new innovations at play, technical advancements, governmental policies and markets have never been so intertwined. Here, we generally describe the concepts of Industry 4.0, explain some new terminologies and challenges for clarity and completeness. The key of this paper is that we summarise over 14 countries’ up-to-date national strategies and plans for Industry 4.0. Some of them are bottom-up, such as Portugal, some top-down, such as Italy, a few like the United States had already been moving in this direction long before 2011. We see governments are tailoring their efforts accordingly, and industries are adapting as well as driving those changes.

AbstractRampant use of groundwater for drinking purposes in several parts of the world has raised the concern over its quality. Owing to increasing population, overuse, and pollution of surface water sources, the use of groundwater has increased to considerable extent. Despite this, little attention is paid towards the monitoring of groundwater resources to assess their suitability for drinking purposes. To assess the groundwater quality in rural areas of Ujjain District of Madhya Pradesh, India, in order to check its suitability for drinking purpose, water quality analysis was done at seven time points during the two study years in six villages of Ujjain District, Central India. A total of 868 groundwater samples from 124 households were collected, and standard analytical methods were employed for analysis. Overall groundwater quality of the area is good and qualified for drinking. However, occurrence of high amount of dissolved solids (> 800 mg/L) and hardness (> 400 mg/L) is the issue of concern, as long-term use of such water might result in variety of health ailments, such as kidney stones and atopic dermatitis in children. Regular monitoring and long-term surveillance of drinking water sources are necessary to keep track of the changes occurring in the system.

Published: January 2021

AbstractThe purpose of this paper was determining the effects of two nanoparticles additions in a commercial epoxy coating system on rheology characterization. Two kinds of hybrid organic–inorganic silicates (benzytallowdimethylammonium salts with bentonite) were studied, APA, with C14-16 organic chain and, HT, with C2-4 organic chain. A 22 factorial design, with two categorical nanoparticules factors was applied. The experimental data of viscosity were fit to three different rheological constitutive models: Herschell-Bulkley, Carreau-Yasuda and Cross. The best fit was obtained by Herschel-Bulkley model. The APA nanoparticle had substantial changes in yield stress values, but no effect was observed when HT had been isolated. Two thixotropic models were analyzed for the epoxy system, and the better performance was observed for the model with two rheological parameters. The presence of nanoparticule in epoxy coating reduced around 40% the recovery time. The addition of nanoparticules changes the rheological properties of a commercial coating. The X-Rays Diffraction analyses were done to observe the dispersions degree and exfoliations in the epoxy system. The crystalline peak of nanoparticles had lost for all coating formulations. The electromagnetic interference shielding attenuation was 60% in the formulations with high content of both nanoparticles. The APA and HT improved hence, the anticorrosion performance of the epoxy coating for 720 h in chloride solution. Corrosion resistance had the best performance in the coating with high concentration of carbon black and nanoparticles.

Published: January 2021

AbstractIn this study, we present the synthesis, spectroscopic and structural characterization of self-assembling gem-dimethyl imine based molecular cage (IMC). Self-assembling macrocycles and cages have well-defined cavities and have extensive functionalities ranging from energy storage, liquid crystals, and catalysts to water splitting photo absorber. IMC has large voids i.e., 25% of the total crystal volume thus could accommodate wide substrates. The synthesized imine-based molecular cages are stabilized by coaxial π bonded networks and long-range periodic van der Waal and non-bonded contacts as observed from the crystal structure. IMC also has typical properties of soft condensed matter materials, hence theoretical prediction of stress and strain tensor along with thermophysical properties were computed on crystal system and were found to be stable. Molecular dynamics revealed IMC is stabilized by, strong interactions between the interstitial phenyl rings. Density functional theory (DFT) based physicochemical properties were evaluated and has band gap of around 2.38ev (520 nm) similar to various photocatalytic band gap materials.

AbstractNanofluids are proven to be the next-generation smart fluids with tunable thermal and viscous properties. Nanomaterial concentration plays a vital role in determining the heat transfer and viscous transport characteristics. An optimum concentration is generally required to regulate a feasible and economical heat transfer operation. This research involves the modeling and optimizing different temperature-dependent thermal and viscous parameters for varying concentrations of nanofluids. The nanofluids consist of functionalized alumina (f–Al2O3) nano-dispersions in thermal oil (highly refined mineral oil). The experimentally measured temperature-dependent nanofluids' properties are used to optimize thermophysical parameters using Response Surface Methodology. Two case studies/scenarios are considered in the present research, where the primary objective is to maximize thermal conductivity for heat transfer applications and minimize nanoparticle loadings for economical operation. The input parameters include temperature and nanoparticle loadings. The output parameters or response include thermal conductivity, viscosity, density, and specific heat of nanofluids. For case study 1, the optimal findings for the thermal conductivity, viscosity, density, and specific heat are 0.146061 W/m °C, 0.031889 Pa.s, 838.529 kg/m3 and 1533.9 j/kg °C, respectively. For case study 2, the optimal findings for thermal conductivity, viscosity, density, and specific heat are 0.13476 W/m °C, 0.0226062 Pa.s, 831.071 kg/m3 and 1791.14 j/kg °C, respectively. Although the optimal value for thermal conductivity decreased in case study 2, the nanoparticle weight % was reduced from 1 to 0.322473%.
Does Resisted Sled Towing Improve the Physical Qualities of Elite Youth Soccer Players of Differing Maturity Status?
Authors: Morris Rhys , Myers Tony , Emmonds Stacey , Singleton Dave , Till Kevin 
Published: January 2021

Abstract
Purpose
Sled towing has been shown to be an effective method to enhance the physical qualities in youth athletes. The aim of this study was to evaluate the impact of a 6-week sled towing intervention on muscular strength, speed and power in elite youth soccer players of differing maturity status.

Method
Seventy-three male elite youth soccer players aged 12–18 years (Pre-Peak Height Velocity [PHV] n = 25; Circa-PHV n = 24; Post-PHV n = 24) from one professional soccer academy participated in this study. Sprint assessments (10 m and 30 m), countermovement jump and isometric mid-thigh pull were undertaken before (T1) and after (T2) a 6-week intervention. The training intervention consisted of 6 weeks (2 × per week, 10 sprints over 20 m distance) of resisted sled towing (linear progression 10%–30% of body mass) during the competitive season. Bayesian regression models analysed differences between T1 and T2 within each maturity group.

Results
There were minimal changes in strength, speed and power (P = 0.35–0.80) for each maturity group across the 6-week intervention. Where there were changes with greater certainty, they are unlikely to represent real effect due to higher regression to the mean (RTM).

Conclusion
It appears that a 6-week sled towing training programme with loadings of 10%–30% body mass only maintains physical qualities in elite youth soccer players pre-, circa-, and post-PHV. Further research is required to determine the effectiveness of this training method in long-term athletic development programmes.
Spirit's Embeddedness in Nature: Hegel's Decentring of Self-Legislation
Authors: Ikäheimo Heikki 
Published: January 2021

AbstractA recently widely accepted view has it that the nature-spirit distinction in Hegel is to be understood as a distinction between a space or realm that is not normative, or does not involve norms, and one that is or does. Notwithstanding the merits of this view, it has tended to create a separation between nature and spirit which is both philosophically troubling and difficult to reconcile with the picture of Hegel as the arch enemy of abstract or unreconciled dualisms. In this paper I aim to show that the defining phenomenon for this view—collective self-government by norms—is on Hegel's account both dependent on living nature that involves normativity broadly conceived all the way down and also subject to the ultimate normative or evaluative principle of Hegel's Philosophy of Spirit—concrete freedom—the essence of spirit according to him. This is to say that for Hegel the normativity of collectively administered norms is neither the most basic nor the highest form of normativity.
A counterexample to the Bollobás–Riordan conjectures on sparse graph limits
Authors: Sah Ashwin , Sawhney Mehtaab , Tidor Jonathan , Zhao Yufei 
Published: January 2021

AbstractBollobás and Riordan, in their paper ‘Metrics for sparse graphs’, proposed a number of provocative conjectures extending central results of quasirandom graphs and graph limits to sparse graphs. We refute these conjectures by exhibiting a sequence of graphs with convergent normalized subgraph densities (and pseudorandom C4-counts), but with no limit expressible as a kernel.
