Work-family conflict and partners' agreement on fertility preferences among dual-earner couples: Does women's employment status matter?

Objective: This study tests the effects of work-family conflict, in both directions, on partners' agreement on fertility preferences among dual-earner couples, as well as whether this relationship varies by women's employment status. Background: Few studies have examined the relationship between work-family conflict and fertility preferences. Given the high percentages of women working part-time in Germany, it is important to investigate the role working women’s employment status plays to further understand this relationship. Method: Using data from 716 dual-earner couples in Wave 10 of the German Family Panel (pairfam), we use dyadic data analysis to test whether work-family conflict impacts one’s own ("actor effects") and/or one’s partner’s ("partner effects") reports of agreement on fertility preferences. We also run multi-group analyses to compare whether these effects vary in "full-time dual-earner" versus "modernized male breadwinner" couples. Results: There are significant actor effects for family-to-work conflict in both types of couples, and for work-to-family conflict in modernized male breadwinner couples only. Partner effects for family-to-work conflict exist only among modernized male breadwinner couples. While there are no gender differences in actor or partner effects, results suggest differences in the partner effect (for family-to-work conflict only) between these two couple types. Conclusion: These findings indicate that work-family conflict is associated with greater partner disagreement on fertility preferences and highlight the differential impact incompatible work and family responsibilities have on fertility decisions when women work full-time versus part-time.
Tackling gender bias in equity crowdfunding: an exploratory study of investment behaviour of Latin American investors

Purpose Belonging to the financial technologies’ companies, equity-based crowdfunding platforms offer investors the opportunity to become shareholders through the purchase of small equity stakes of new innovative ventures. This paper aims to investigate gender-related differences in the behaviour of investors in firms seeking equity financing in Latin America. Design/methodology/approach Using a unique database, with combined information from different equity crowdfunding platforms in Brazil, Chile and Mexico, the authors study the population of 492 projects between 2013 and 2017. To analyse the relationship between investors’ gender-related differences and equity crowdfunding investment, this paper applies Poisson regression. Findings Results suggest that the probability that an investor finances a firm is based on gender bias. Investors prefer firms led by entrepreneurs that are similar to them in terms of gender. Furthermore, the authors find evidence that both female and male investors are risk-averse and are more likely to invest in the equity of firms that are older and offer a higher percentage of equity. However, female investors are associated with firms that are on average older and offer 0.02% more equity. Practical implications These findings have implications for crowdfunding platforms managers when selecting their target companies and policymakers when defining political actions to promote greater use of equity crowdfunding among female entrepreneurs and decrease barriers hindering women’s access to investment. Originality/value Unique in its proposition and data usage, this study sheds light on the relationship between investors and entrepreneurs in the Latin American equity crowdfunding market.
Numerical Simulations of Steel Integral Abutment Bridges under Thermal Loading

AbstractAlthough integral abutment bridges (IABs) can reduce construction and maintenance costs compared with conventional jointed bridges, certain aspects of their structural behavior are still not well understood. Most prior IAB research was related to substructure behavior, and as a result, most limit states that have been considered in design guidelines have been based on substructure considerations. However, integral abutment construction also affects superstructure behavior and demands, and superstructure properties directly influence substructure behavior. This paper presents numerical simulations evaluating the behavior of IABs with composite steel I-girders subjected to temperature changes consistent with seasonal fluctuations in the state of Illinois. Bridge superstructures, abutments, piers, and pile foundations were modeled to determine various structural demands imposed by these temperature changes. A suite of nonlinear bridge models is introduced in which key bridge parameters were varied, s.
Changes in the lipid profile of neutered cats’ blood in cases of obesity and diabetes

The aim of the present study was to examine the lipid profile, lipid fractions and the lipid peroxidation state in the blood of neutered cats with obesity and diabetes. Three groups of neutered cats (males and females) were formed for the study. We compared cats with obesity (7-9 points on a 9-point BCS scale), with obesity complicated by diabetes, and clinically healthy animals with normal body condition scores (4-5 BCS points). Lipidogram parameters, fractions of high-density lipoprotein (HDL), low-density lipoprotein (LDL) and very low-density lipoprotein (VLDL), chylomicrons (CM), lipid peroxidation products (POL) - lipid hydroperoxides (GPL) and malondialdehyde (MDA) were analysed. In obese cats, a decrease in HDL and phospholipids was observed, and an increase in LDL, VLDL, CM, triglycerides, and cholesterol. No significant differences in lipid and lipoprotein metabolism between neutered females and males were found. A tendency towards increasing concentrations of lipoproteins, triglycerides and cholesterol in males, as well as an increase in phospholipids in females was found. In cats with obesity and associated diabetes, the ratio of phospholipids: cholesterol was less than one, while in healthy cats - more than one. Obesity and diabetes initiate POL and increased concentrations of GPL and MDA, which were the highest in the blood of females with associated pathology.
Lignocellulose Nanofiber Media for the Enhanced Removal of Copper From Aqueous Solutions

Nowadays, the entry of heavy metals entry into aqueous environments has jeopardized the health of human societies. The experiment was conducted in discontinuous conditions, and the study focused on examining the effect of five parameters including initial concentration, temperature, contact time, pH, and adsorbent dose on the adsorption of Cu heavy metals. In addition, the two-parameter models of Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich were studied and compared to evaluate isothermal absorption. The highest correlation coefficients were obtained for Freundlich (0.969) and Dubinin-Radushkevich (0.9603) models. Finally, thermodynamic parameters such as enthalpy and entropy changes and Gibbs-free energy were calculated as well. The pH parameters, adsorption dose, contact time, temperature, and initial Cu concentrations in the discontinuous system had a statistically significant effect on the adsorption process. The results showed that the maximum efficiency of Cu adsorption by Lignocellulose nanofiber (LCNF) occurred at the pH of 6, contact time of 60 minutes, the ambient temperature of 25°C, and adsorption dose of 0.2 g. In the case of adsorption kinetics, the pseudo-second order model and intra-particle diffusion had more fitness with the experimental data indicating a chemical equilibrium between the adsorbate and the absorbent. Thermodynamic studies demonstrated that the process (negative ΔG) is spontaneous (negative ΔG), endothermic (negative ΔH), and non-random (positive ΔS). Thus, LCNF can be used as an effective adsorbent in the removal of metals by having an extremely high surface area.
DESCRIPTION OF SPEECH DELAY IN EARLY CHILDHOOD

Every parent expects their children to grow normally. However, some factors may affect the children's growth and bring about the delay of their getting old. There are several reasons, internally and externally, that lead to impaired child development. Parents are making some efforts to handle this situation, especially when it is related to speech. This writing aims to describe the factors influencing the delay of the children in speaking. The data were taken from around 5 of 7-8 years old children who suffered from speech delays in Padang city. The observational method with note-taking and interviewing techniques was involved in collecting the data. By using the concept of speech delay, the data were analyzed. After analyzing the data, it is found that some factors are causing the speech delay. They are 1) family relationship, 2) speech model and 3) gadget-cholic.
Biochemical Effects of Low Crude Protein Diets Supplemented with Varying Methionine Concentrations

The research investigated the consequences of decreased crude protein (CP) and methionine supplementation in diets on certain biochemical indices in broiler chicks. A total number of 135 newly hatched chicks were allotted to nine dietary treatments, 3 replicates of five birds each. Groups A-C served as the control with 20% CP and 0.6, 1.0 and 1.4% methionine supplementation. Groups D-F and G-I were placed on 17 and 14% CP diets respectively, with similar methionine supplementation as the control groups. The experiment lasted six weeks. Vital biochemical parameters studied include alkaline phosphatase, aminotransferases, superoxide dismutase, catalase, malondialdehyde, and organ-body weight ratios. Findings from the study indicated that there was a significant (p<0.05) reduction in alkaline phosphatase activities of tissues of birds placed on 17 and 14% CP as correlated with birds on the control. MDA concentration was significantly (p<0.05) elevated in the liver, kidney, and heart of broiler chicks fed diets with 14 and 17% CP at all methionine levels investigated when compared to control (20% CP). The low crude protein with varying methionine concentrations in broiler chick diets had no negative impact on birds’ vital organs relative to whole body weight. These findings thus concluded that the functions and not size of the organs studied in broiler chicks were adversely affected at CP levels below 20%.
The Trusting Beliefs of Users and the Intention to Continue Making Purchases via Social Commerce

Introduction/Main Objectives: This study aims to examine the influence of a user’s trusting beliefs on the intention to continue making purchases via social commerce. Indonesia is ranked 4th in the world for the most active online users of social media. Thus, it is necessary to investigate the influence of those variables. Background Problems: Social networks contribute to online trading by providing platforms for social commerce. The author chose the trusting beliefs concept and linked it to online users’ trust in social commerce. Novelty: Trusting beliefs variables are fundamental in shaping online users’ behaviors, but no prior research has investigated the effect of trusting beliefs on the intention to make purchases via social commerce. This study presents new research that provides a comprehensive model related to social commerce. Research Methods: This research uses purposive sampling of people who are required to have social media accounts and who have made purchases via social commerce at least once with data taken from surveys. The research uses Structural Equation Modelling (SEM). Finding/Results: This study proves that all trusting beliefs variables are supported and significant, but there is one hypothesis that is not supported (H4). Empirically, this indicates that active users are not necessarily engaging in online shopping using their social media. Conclusion: This study provides insights into the potential role of trusting beliefs driving continuing purchases in the context of social commerce research. We suggest that the sellers need to give customers-to-be more frequent and wider product reviews information so they can get results in terms of stronger product image and motivate them to make purchases via social commerce.
Risk Factors for Postoperative Deep Infection after Instrumented Spinal Fusion Surgeries for Degenerative Spinal Disease: A Nationwide Cohort Study of 194,036 Patients

Previous studies to identify risk factors for postoperative deep infection following instrumented spinal fusion surgery for degenerative spinal disease are based on insufficient information and have limited use in clinical practice. This study aims to fill this gap by assessing the risk factors and their adjusted relative risks through a comprehensive analysis, including all core information. In this nationwide, population-based, cohort study, data were obtained from the Korean National Health Insurance claims database between 1 January 2014, and 31 December 2018. This study included a cohort of 194,036 patients older than 19 years, who underwent instrumented spinal fusion surgery for degenerative spinal disease. We divided this population into cases (patients with postoperative deep infection) and controls (patients without postoperative deep infection); risk factors for postoperative deep infection were determined by multivariable analysis. The definition of postoperative deep infection varied, and sensitivity analyses were performed according to each definition. The estimates of all the statistical models were internally validated using bootstrap samples. The study included 767 patients (0.39%) with postoperative deep spinal infections and 193,269 controls. The final multivariable model identified the following variables as significant risk factors for postoperative deep infection: age between 60–69 years (OR = 1.6 [1.1–2.3]); age between 70–79 years (OR = 1.7 [1.2–2.5]); age > 80 years (OR = 2.1 [1.3–3.2]); male sex (OR = 1.7 [1.5–2.0]); rural residence (OR = 1.3 [1.1–1.5]); anterior cervical approach (OR = 0.2 [0.1–0.3]); posterior cervical approach (OR = 0.5 [0.2–1.0]); multiple approaches (OR = 1.4 [1.2–1.6]); cerebrovascular disease (OR = 1.5 [1.2–1.8]); peripheral vascular disease (OR = 1.3 [1.1–1.5]); chronic pulmonary disease (OR = 1.2 [1.0–1.4]); rheumatologic disease (OR = 1.6 [1.3–2.1]); liver disease (OR = 1.4 [1.1–1.7]); diabetes (OR = 1.5 [1.3–1.7]); hemiplegia or paraplegia (OR = 2.2 [1.5–3.3]); allogenous transfusion (OR = 1.6 [1.3–1.8]); and use of systemic steroids over 2 weeks (OR = 1.5 [1.1–2.0]). Our results, which are based on homogenous patient groups, provide clinicians with an acceptable tool for comprehensive risk assessment of postoperative deep infection in patients who will undergo instrumented spinal fusion surgery for degenerative spinal disease.
Women in paid employment: a role for public policies and social norms in Guatemala

ABSTRACT With only 32% of women in the labor market, Guatemala has one of the lowest rates of female labor force participation (FLFP) in the Latin America and Caribbean region and in the world. We explore information from different micro data sets, including the most recent population censuses (2002 and 2018) to assess the drivers of recent progress. Between 2002 and 2018, FLFP increased from an average of 26% to 32% nationwide. This increase was partly explained by increases in the school attainment of women, reduction in fertility and the country’s structural transformation towards services. However, a large part of the increase remains unexplained. Exploring 2018 data, we show that social norms, attitudes towards women and public policies are important determinants of FLFP. The analysis suggests that, taken together, these factors can all become an important source of increased participation of women in the labor market moving forward 1 .
Numerical evaluation of micro-channel flow characteristics in T-groove dry gas seal

Based on Navier-Stokes equation and considering the effect of micro-scale flow on the interior flow field in dry gas seals a nonlinear motion equation was derived for a stationary flow field in T-groove.By using finite-difference method,the nonlinear partial differential equation was transformed into the linear algebraic equation group by iterative increment linearization method.The pressure distribution and velocity field in T-groove dry gas seal was obtained with numerical calculation.The approximate gas leakage and opening force distribution were determined for different gas film thickness.The evaluation result was basically consistent with that of experiments listed in literatures available,verifying the feasibility of this theoretical analysis method for the optimum design of dry gas sealing system.
A Full-length Quench Antenna for MQXFA Production Series Quadrupole Magnet Testing

The MQXFA production series quadrupoles being built for the Hi-Lumi (HL) LHC upgrade by the US Accelerator Upgrade Project (US-HL-LHC AUP) will have very limited instrumentation for characterizing quench events that occur during magnet training and performance validation testing. In order to understand the origin of the quenches, and whether they have some implication for ongoing magnet fabrication, it was decided to build a full-length Quench Antenna (QA) with axial resolution of 50mm to be employed during cold testing in the anticryostat used for magnetic measurements. The goal is to have fineresolution, full-length coverage detection of quench events axially, as well as to have azimuthal resolution on the order of the cable width (about 1 degree for the cross-section), in a device that can be used both for vertical and horizontal testing. To achieve this, a 5 m long QA with 128 channels of high-speed data acquisition has been designed and fabricated. The cylindrical antenna features an array of 12 full-length, dipoleand quadrupole-bucked coils positioned radially in the QA interior for azimuthal localization, and over 100 individual channels of short, high-sensitivity, antennas etched as flexible PCB circuits (which also buck dipole and quadrupole fields) wrapped circumferentially on the cylinder exterior in steps of 50 mm along the magnet length for axial detection. This paper discusses the design, construction and analysis of the MQXFA QA, and first results from using the antenna during quench testing in the production magnets. 
Evaluation of insecticidal efficiency of Basalt powder “Farina di Basalto

Background: This work aims to evaluate under laboratory conditions the insecticidal effect of Basalte, which is a volcanic rock and a natural fertilizer rich in nutriments and employed to improve crops growth, on insect pests of stored wheat ; Tribolium castaneum (Coleoptera, Tenebrionidae), Rhyzopertha dominica (Coleoptera, Bostrichidae) and Ephestia kuehniella (Lepidoptera, Pyralidae). Three treatments were applied: T0: without “Farina di Basalto” (Control), T1: 3% of “Farina di Basalto”, T2: 1.5% of “Farina di Basalto”. Obtained results showed that the fertilizer causes the mortality of the three pest species. Regarding T. castaneum, mortality rates observed for the control were always about 0% until the fifth day of observations. However, in treated units, insect mortality rates were about 40 and 16.6% respectively for 3 and 1.5% of basalt powder just one day after the trial and increased considreably thereafter and reached 100% during the third and fourth days after treatment. Almost same results were obtained for R. dominica where mortality rates observed in control were low during the first three days and did not exceed 10%, while in treated units they reached 100% during the second and third day after treatment respectively for the doses 3% and 1.5% of basalt. Regarding larvae of E. kuehniella, mortality rates observed in control remained low until the seventh day and slightly exceeded 50% during the rest of the trial. In treated units with 3% of basalt, mortality rates were about 60% during second and third day after treatment and reached 100% during fourth day. For treated units by 1.5% of basalt, mortality rates ranked between 20 and 40% till the fifth day to reach 90% at the end of the trial.
Linguistic Features of Discourse within an Algebra Online Discussion Board

This study leverages natural language processing to assess dimensions of language and discourse in students’ discussion board posts and comments within an online learning platform, Math Nation. This study focusses on 1,035 students whose aggregated posts included more than 100 words. Students’ wall post discourse was assessed using two linguistic tools, Coh-Metrix and SEANCE, which report linguistic indices related to language sophistication, cohesion, and sentiment. A linear model including prior math scores (i.e., Mathematics Florida Standards Assessments), grade level, semantic overlap (i.e., LSA givenness), incidence of pronouns, and noun hypernymy accounted for 64.48% of the variance for the Algebra I end of course scores (RMSE=13.73). Students with stronger course outcomes used more sophisticated language, across a wider range of topics, and with less personalized language. Overall, this study confirms the contributions of language and communication skills over and above prior math abilities to performance in mathematics courses such as Algebra.
Prevalence and Types of Fungi in Kintamani Bali Dogs

Indonesia, located in the tropics with high humidity, is a suitable area for the growth of various types of fungi. Kintamani Bali dogs have thick and beautiful fur, so it is unfortunate to get a fungal infection. There is a high risk for fungal infection, and no research data for Kintamani Bali Dog make this research very important. Samples were taken randomly from Kintamani Bali dogs with fungal disease characteristics using the toothbrush technique. The samples were identified by colony identification and microscopic examination through slide culture using Methylene blue staining. The results showed that from 15 samples, identified 31 fungi. Among these, commonly found were Aspergillus sp. 54.84% and each of Curvularia sp. Trichophyton sp. Candida sp. 12.9% while Penicillium sp. 6.45%. Based on sex, generally, the female Kintamani had a higher (61.29%) fungal infection than male Kintamani Bali dogs (38.71%). In young age dogs, more infection was found (70.97%) than adult dogs (29.03%).
Experimental and Theoretical Radiative Parameters of Highly Excited Levels in Re ii

Natural radiative lifetimes of 22 odd-parity levels of Re ii in the energy range between 43,937.7 and 65,572.3 cm−1 were measured by the time-resolved laser-induced fluorescence method. To our knowledge, the lifetimes for 18 out of 22 levels were measured for the first time. The theoretical radiative lifetimes and branching fractions (BFs) for these levels were obtained from pseudorelativistic Hartree–Fock calculations including core-polarization effects. By combining the experimental lifetimes and calculated BFs, a set of semiempirical transition probabilities and oscillator strengths for 232 Re ii lines were determined. The radiative parameters obtained in the present work will greatly enrich the atomic database of Re ii and hence are expected to be helpful for astrophysicists in Re abundance evaluation of stars.
