Published: December 2022

AbstractThough studies have examined the role of social support in the lives of Black men, less is known about the role and function of multi‐domain social support as they navigate fatherhood. This investigation utilizes a profile‐oriented approach to identify patterns of general and parenting‐specific social support (i.e., family; peers; community) among a sample of 759 Black American fathers. Additionally, this study examines how identified support profiles are associated with Black fathers' parenting outcomes (i.e., stress, satisfaction, self‐efficacy, and involvement). Latent class analyses identified 10 distinct social support profiles among Black fathers. Results also indicated that there was some profile variation in levels parenting outcomes. Findings suggest variation in the availability and utilization of general and parenting support among Black fathers.
The decision to customize and its effect on brand experience
Authors: Petruzzellis Luca , Winer Russell S. 
Published: December 2022

AbstractNowadays brands are using customization strategies to reach their consumers with experiences that perfectly fit their preferences. At the same time, with customization consumers could effectively dilute the impact of the company's brand. Despite the robust literature on customization, little attention has been paid to how the decision to customize is linked to the brand experience. This paper aims to better understand the mechanisms behind customization choice in terms of preferences and assess the role of brand experience in this decision. We hypothesize a positive relationship between customization and brand experience. Moreover, since customization has a strong emotional component, we also analyze the moderating role of cognitive and psychological factors in shifting consumer preferences—from technical performances to emotional and symbolic ones. Through a two‐equation model that encompasses a number of factors, we find strong support for the main effect of an improved brand experience when consumers are permitted to customize the offering.

Published: December 2022

AbstractLeachate head in municipal solid waste (MSW) landfills can be very high (e.g., >10 m) in some Chinese landfills and can continuously change during the service life of the landfill. Variations of leachate head can induce time‐dependent seepage velocity changes in the liner, which may lead to a change of transport mechanisms of contaminants. An analytical model for contaminant transport through clay liner system considering the effects of leachate head variations is presented. The analytical solution is obtained using the recursive method and the Green's function approach. The proposed analytical solution is verified by numerical results. The model is then applied to investigate the effects of variable leachate head on the transport of contaminants. The results indicated that time‐dependent advection arising from leachate head variations may play a significant part when investigating contaminant transport through a clay liner. The contaminant concentrations at the bottom of the liner predicted by using fixed leachate head may be underestimated compared to the case with variable leachate heads. The bottom concentration of Pb2+ at t = 50 years for the case with HD = 60 m can be 6.6 times larger than that of the case with fixed leachate head. The mechanisms of contaminant transfer may change from a diffusion‐dominated process to an advection‐dominated process. For example, the molecular diffusion is the dominant process in Event 1 (e.g., t < 5 years with Peclet number < 1) while advection induced by the variations of leachate head may play a more important role for contaminant transport when t > 5 years. Increasing leachate head can result in an earlier breakthrough time and steady state for contaminant transport. The breakthrough time of DCM for the case with HD = 60 m can be 1.6 times lower than that for the case with fixed leachate head. Considering the effects of leachate head variations may be critical to design a more stable and reliable landfill liner.
Shape optimization method for strength design problem of microstructures in a multiscale structure
Authors: Torisaki Mihiro , Shimoda Masatoshi , Al Ali Musaddiq 
Published: December 2022

AbstractIn this paper, we propose a solution to a shape optimization problem for the strength design of periodic microstructures in multiscale structures. Two maximum stress minimization problems are addressed: minimization of maximum microstructural stress and minimization of maximum macrostructural stress. The homogenization method is used to bridge the macrostructure and the microstructure and to calculate local microstructural stress. By replacing the maximum stress value with a Kreisselmeier‐Steinhauser function, the difficulty of nondifferentiability of maximum stress is avoided. Each strength design problem is formulated as a distributed parameter optimization problem subject to an area constraint including the whole microstructure. The shape gradient functions for both problems are derived using Lagrange's undetermined multiplier method, the material derivative method, and the adjoint variable method. The H1 gradient method is used to determine the unit cell shapes of the microstructure, while reducing the objective function and maintaining smooth design boundaries. In the numerical examples, the optimal shapes obtained for minimization of the maximum local stress of the microstructure and the macrostructure are compared and discussed. The results confirm the effectiveness of the microstructure shape optimization method for the two strength design problems of multiscale structures.

Published: December 2022

AbstractThe effect of three types of nanofillers on the physical, mechanical, and thermal properties of flexible polyurethane foams (FPUF) was studied. FPUF with nanofillers are of interest to the automotive industry due to their potential for enhancing compression properties and enabling sustainable foams. Holey and wrinkled flash graphene, and untreated and silane coated boron nitride were tested as fillers up to 0.1 wt% loading level. Flash graphene filled FPUF showed significant improvement in compressive properties, especially at the 0.025 wt% loading level, showing a 22% increase in compressive force deflection at 25% strain and a 17% increase at 50% strain compared to the unfilled control foam sample. Boron nitride nanoparticles, treated and untreated, were shown to be an effective means of reducing wet compression set properties, addressing a key area of concern for sustainable polyols. Wet compression set was reduced by 20%–30% for most boron nitride foams compared to their unfilled control samples. Boron nitride may enable implementation of more sustainable polyols in automotive FPUF. Nanofillers did not significantly improve thermal stability of FPUF.

AbstractIntroductionPanax notoginseng (Burkill) F. H. Chen ex C. H. Chow, is a well‐known herb with multitudinous efficacy. In this study, a series of overall analyses on the action mechanism, component content, origin identification, and content prediction of P. notoginseng are conducted.ObjectivesThe purpose was to analyse the mechanism of pharmacological efficacy, differences between contents and groups of P. notoginseng from different origins, and to identify the origin and predict the content.Materials and methodsThe P. notoginseng samples from four different origins were used for analysis by the database, network pharmacology (Q‐marker) and fingerprint analysis [high‐performance liquid chromatography (HPLC), attenuated total reflectance Fourier‐transform infrared (ATR‐FTIR) and near‐infrared (NIR)] combined with data fusion strategy (low‐ and feature‐level).ResultsFour saponins were identified as Q‐markers, and exerted pharmacological effects on signalling pathways through 24 core targets. The qualitative and quantitative analysis of HPLC showed that there were differences among groups and different origins. Therefore, considering the need to treat diseases, combined with network database and network pharmacology, the suitable producing areas were determined through the mechanism of action and the required saponin content. The low‐level data fusion successfully identified the origin and predicted the content of P. notoginseng from different origins. The accuracy rate of each evaluation index of the partial least squares discriminant analysis (PLS‐DA) model was 1, and the t‐SNE (t‐distributed stochastic neighbor embedding) visualisation results were good. The coefficient of determination (R2) of the partial least squares regression (PLSR) model ranged from 0.9235–0.9996, and the root mean square error of cross‐validation (RMSECV) and root mean square error of prediction (RMSEP) range is 0.301–1.519.ConclusionThis study was designed to provide a sufficient theoretical basis for the quality control of P. notoginseng.

AbstractThis paper studies the structural formation of various spherically symmetric anisotropic configured stars in gravity under the influence of electromagnetic field, where . We construct modified field equations by adopting the Krori‐Barua metric potentials (involving unknowns ()) and employ bag model equation of state to explore the physical characteristics of compact structures like Vela X‐I, 4U 1820‐30, SAX J 1808.4‐3658, Her X‐I and RXJ 1856‐37. The bag constant () and other three unknowns are calculated by using experimental data of all considered stars. Further, we adopt a standard model to interpret the graphical behavior of energy density, pressure in radial and tangential directions as well as anisotropy. We also investigate mass, compactness parameter, surface redshift and energy conditions for compact bodies by taking model parameter (ϖ) as ±5. The stability of the obtained solution is examined by means of two different criteria. We conclude that our proposed solution meets all the physical requirements and shows stable behavior everywhere for .

AbstractA Co(II) coordination polymer [Co(suc)(bpm)] ⋅ 2H2O (1) built from succinate (suc) and bipyrimidine (bpm) is synthesized hydrothermally and characterized by different methods. It crystallizes in a monoclinic space group P21/n with an intriguing 3D polymeric architecture. The weak antiferromagnetic (AF) exchange interactions were evinced by Curie Constant (C)=1.803 cm3mol−1K and a negative Weiss constant (φ)=−30.163 K. Type VI adsorption isotherm behavior of 1 at 77 K revealed its non‐porous property. Compound 1 was investigated and successfully utilized as an additive in lowering the decomposition temperature of ammonium nitrate (AN) based fuels as demonstrated from TG and DSC experiments performed in nitrogen atmosphere.
Visible‐Light Enabled Late‐Stage, Room‐Temperature Aminocarbonylation of Aryl Iodides with Labeled Carbon Monoxide

Published: December 2022

AbstractIn recent years, coupling reactions mediated by visible light have been widely studied because such reactions can often be run at significantly lower temperatures. In this work, aryl iodides were coupled with amines at ambient temperature in the presence of stoichiometric amounts of carbon monoxide using visible‐light irradiation and palladium catalysis. A wide range of aryl substrates, both electron‐deficient and rich, as well as heterocycles, were carbonylated to provide the corresponding amides in moderate to good yields based on CO. In addition, the generality of the amine was investigated, and primary and secondary amines yielded the desired products in moderate to good yields. This methodology was also successfully applied to the synthesis of pharmaceuticals and the incorporation of a carbon‐14 label into the carbonyl group, where the use of 9‐methyl‐fluorene‐9‐carbonyl chloride (COgen) as the carbon isotope‐labeled CO source allowed easy translation between the unlabeled and the labeled transformations.

AbstractSeveral nitrogen heterocycles are considered as privileged scaffolds in drug discovery and are present in several drugs with diverse biological activities. Herein, we report the synthesis and characterization of phthalazinone derivatives by using a green synthesis protocol under microwave irradiation. The reduced reaction time and high yield are some of the advantages that render this procedure a greener alternative to conventional chemical synthesis. The structures of all new derivatives were confirmed by spectral analysis. Synthesized derivatives show an effective antimicrobial effect. These compounds were also screened for their in vitro anticancer activity against colon cancer cell line (HCT116). Among the synthesized derivatives are exhibited the highest anticancer activity with IC50 of 28.97±0.11, 66.25±0.14 and 76.04±0.09 μM respectively. The antiproliferative activity was supported by molecular docking studies that showed that phthalazinone derivatives would potentially act through inhibition of PARP. The simulation studies substantiated the biological results as an active compounds in term of binding interactions and scores.

Published: December 2022

AbstractBiomineralization is an environment‐friendly strategy for producing inorganic materials, where nitrogen‐doped particles of controlled size can be synthesized. A peptide‐mediated biomineralization was investigated to produce TiO2 particles with enhanced photocatalytic activity. The heptapeptide, HKKPSKS, verified previously as exhibiting TiO2 mineralizing activity, was immobilized on the surface of functionalized polystyrene (PS) bead through N‐ethyl‐N‐(3‐dimethylamino‐propyl) carbodiimide hydrochloride‐N‐hydroxy‐succinimide (EDC−NHS) coupling, so that it acted as the nucleus to trigger TiO2 precipitation on its surface in ambient condition. During the calcination of PS−peptide−TiO2, the PS−peptide template both allowed the formation of porous‐structured particles, and generated nitrogen‐doped crystalline mixed phase (anatase/rutile) TiO2. More than 86 % of bisphenol A (BPA) was decomposed in the presence of optimally calcined TiO2 under visible light in 2 h, whereas commercial P25 catalyst degraded 48 % of BPA. After five cycles of repeated reactions for BPA degradation, the photocatalytic activity of TiO2 decreased by less than 10 %.

AbstractKOtBu mediates the reaction between 2‐amino arylcarbaldehydes and benzyl/alkyl cyanides toward the expeditious formation of 2‐aminoquinolines under transition‐metal‐free conditions. The described transformation proceeds throughin‐situgenerated enimine intermediate from benzyl/alkyl cyanides under KOtBu‐mediated reaction conditions. The substituted 2‐aminoquinolines were realized in excellent yields at room temperature and shorter reaction time. The designed process exhibits operational simplicity and broad functional group tolerance in delivering the products of high significance.
Steel‐fibre reinforced concrete in composite structures as a mean to increase resistance and ductility – Outlook in a new generation of composite structures
Authors: Zanon Riccardo , Schäfer Markus , Ruiz Gonzalo , De La Rosa Ángel , Zhang Qingjie 
Published: December 2022

AbstractSteel‐fibre reinforced concrete is a well‐known material used for decades for industrial floorings, shotcrete, or other specific applications. Its use is now spreading in structural applications as a complement or a substitute for conventional bar‐reinforced concrete since the normative framework is ready to provide design approaches for several concrete applications. Nevertheless, some adaptations are needed for implementing steel‐fibre reinforced concrete in the design approach for steel‐concrete composite structures whereby complementary aspects need to be considered. In this field, besides the increase of tensile properties and durability of the concrete member, a very important contribution may be given by the increase of the concrete ductility in compression. This property is conferred by the steel fibres which provide a confinement effect increasing the plastic damage that the concrete matrix can absorb. If this property is widely accepted, its benefits are limited for the design of conventional concrete sections. Conversely, for composite sections, the possibility to reach higher strains in compression means ensuring full exploitation of the strength capacity of structural steel. Besides reaching an optimisation of already in‐use cross‐sections, this new material combination enhances the use of higher structural steel strengths in composite structures.

Published: December 2022

AbstractManagement of intra‐abdominal abscesses complicating Crohn's disease (CD) is challenging. After initial drainage and antibiotherapy treatment, surgery with delayed intestinal resection is often recommended but new data suggests efficacy of biotherapies in this context. This review aims to summarize new data regarding efficacy and safety of anti‐TNF in the management of intra‐abdominal abscesses complicating CD. We performed a review of the literature on medical management of intra‐abdominal abscesses complicating CD. After effective drainage of abscess, treatment with anti‐TNF can allow resolving of abscess. In some patients and at a specific timing, the use of biotherapies could avoid delayed surgery and long‐term abscess recurrence.

Published: December 2022

AbstractNanofluid is a novel heat transfer fluid with the ability to significantly improve the heat transfer efficiency of regular fluids. Many efforts have been made to study its viscosity and thermal conductivity, both of which are crucial thermophysical properties. This work reports the significance of nanofluid along with thermophoretic and Brownian motion phenomena on the Agrawal flow towards a stagnation point past a permeable moving disk. The impacts of the Maxwell velocity slip and Smoluchowski temperature conditions are also incorporated. The leading equations in form of PDEs (Partial differential equations) are simplified into ODEs (Ordinary differential equations) by employing similarity theory. Then these simplified equations are solved numerically by utilizing a bvp4c solver (fourth‐order boundary value problem).The phenomenal effects of the relevant embedded distinguished parameters on the shear stress, rate of mass, and heat transfer are demonstrated through different graphs and tables. Graphical results indicate that double solutions are detected for stretching/shrinking parameter in a certain range. The heat transport and the wall drag force ascend with the suction aspect, while the mass transfer rate drops with suction in both solutions.
Ending Gender-Based Violence in Kyrgyzstan: Reflections on the Spotlight Initiative
Authors: Maralbaeva Aliia , Pierobon Chiara 
Published: December 2022

AbstractThe Spotlight Initiative (SI) is a new global, multi-year initiative launched by the European Union (EU) in cooperation with the United Nations (UN), with the aim of eliminating all forms of violence against women and girls (VAWG) worldwide. Since 2019, Spotlight has been implemented in Kyrgyzstan, where more than 6.5 million US dollars have been allocated to recipient UN Organizations such as UN Women, UNDP, UNPFA, UNICEF and UNODC for the conduct of activities across the initiative’s six outcome areas. This chapter familiarizes the reader with the phenomenon of domestic violence in Kyrgyzstan and with the major legal and institutional barriers hindering access to justice on behalf of female victims of domestic violence. It then examines how the SI has sought to improve access to justice on behalf of female victims of domestic violence by stimulating ownership of an array of state and non-state actors engaged in addressing domestic violence from a legal perspective. The research uses a mixed-method approach, combining a legal analysis of national legislation, an analysis of 280 court judgements on domestic violence and expert interviews with implementers of the Initiative, as well as policy and legal experts, lawyers and civil society activists engaged in the field of VAWG. The study provides recommendations on how to improve the national legislation concerning domestic violence in Kyrgyzstan as well as the implementation of the Spotlight Initiative in the country and beyond.
The Role of Teahouses in Central Asia: A Case Study of the Ferghana Valley
Authors: Schweitzer Ryan 
Published: December 2022

AbstractTeahouses (chaikhana) in the Ferghana Valley of Kyrgyzstan, Tajikistan, and Uzbekistan provide social benefits and help facilitate the development of civil society. Civil society formation in Central Asia does not operate in the same ways as conventional accounts of civil societies claim due to government control, interference, and repression. As such, civil society forms in the peripheries of society, outside the reach of government control. Through interviews and non-participant observations conducted in 2021 throughout the Ferghana Valley, I aim to understand the specific ways in which chaikhana operate in the social sphere, allowing civil society to function outside the government’s control and, in turn, laying the foundations for civil society development. This research determines that, although governments try to limit the ability of social networks and freedom of expression, these connections occur through meetings in social spaces, such as in teahouses. This research will fill the gaps in understanding why chaikhana are still allowed to operate, even though they are prime locations for the development of civil society. In summary, this research seeks to understand the chaikhana’s role as an integral component of Central Asian civil society and the ways in which it continues to operate under adverse governmental and societal conditions.
