Age, period, and cohort effects contributing to the Great American Migration Slowdown

BACKGROUND Between 1964 and 2019, the percentage of people in the United States who had moved in the previous year decreased from 20.3% to 9.8%. It is unclear whether this trend was driven by period-specific factors that gradually diminished the prospects of moving for the population as a whole or whether distinct features of birth cohorts differentially contributed to the migration slowdown. OBJECTIVE The present study assesses whether the migration slowdown in the United States was primarily driven by period effects or by cohort effects. METHODS Using 46 waves of data across the 1964–2019 Annual Social and Economic Supplements to the Current Population Survey, I estimate a series of mixed-effects models predicting the probability of moving and a linear model with age x period interaction terms predicting the probability of moving. RESULTS Cohort effects are more salient in slowing the rates of migration than are period effects. The migration slowdown occurred in part because members of the Silent and Baby Boom generations, who had a higher probability of moving at all ages, matured out of their prime years of geographic mobility in young adulthood and were replaced successively by members of Generation X, the Millennial generation, and Generation Z, who comparatively have a lower probability of moving. CONCLUSION The findings suggest that migration measures and subnational population projections that rely on period-level inputs might potentially mischaracterize current and future demographic trends in the United States. 1 Rice University, USA.

Three new hypogean species of the false scorpions genus Ephippiochthonius Beier, 1930 (Arachnida: Pseudoscorpiones: Chthoniidae) from the Crimean Peninsula

The fauna of false scorpions of the Crimean Peninsula has been poorly studied, moreover the available studies are represented by a small number of taxonomic [Redikorzev, 1918; Lebedev, 1927; Čurčić, 1984; Zaragoza, 2010; Kolesnikov, Turbanov, 2017, 2018; Turbanov, Kolesnikov, 2020] and faunistic [Lebedinsky, 1904; Ellingsen, 1910; Lebedev, 1914; Pliginsky 1927; Chamberlin, 1949; Schawaller, 1989; Dashdamirov, 1999; Turbanov, Kolesnikov, 2015] publications. The above mentioned publications do not represent the true diversity of false scorpions of the Crimea, a region of the Eastern Mediterranean with a rich biodiversity. However, during the study of the cave biota of the Crimea, we found a number of false scorpions species that belong to the family Chthoniidae Daday, 1888 and identified them as representatives of the genus Ephippiochthonius Beier, 1930. Recently the genus Ephippiochthonius was erected as a valid taxon by Zaragoza [2017]. The genus is widely distributed across the Mediterranean and Macaronesian region, reaching Iran to the east, and Scandinavia to the north. There are records of this genus from other parts of the world (North and South America, ABSTRACT. Three new hypogean species of the false scorpions genus Ephippiochthonius Beier, 1930 from the caves of the Crimean Peninsula, i.e. E. tauroscythicus sp.n., E. volkeri sp.n. and E. pliginskyi sp.n. are described. Diagnostic and ecological features of these species are presented and discussed, as well as compared with the related species of this genus. A hypothesis about a possible scenario of speciation of troglomorphic species of the genus Ephippiochthonius in the caves of the Crimean Mountains in connection with global climate changes is proposed.

Gaseous Diffusion in the Leaf Interior

ABSTRACT A one dimensional, steady state, constant temper-ature model of gaseous diffusion in the leaf interior is presented. The model is shown to predict that C02 is absorbed into mesophyll cell walls generally through-out the deep interior of the leaf, while water vapor essentially evaporates only from those cell walls near the substomatal cavity.

The free-field correction of the speech level was determined to be 3.2 dB. Conclusions Free-field correction values were determined for RadioEar DD65v2 audiometric headphones with an expanded measurement uncertainty.
Hydrologic design aid for urban grass filter strips

A set of generalised charts are presented in this article as a design aid for hydrologic sizing of grass filter strips. The charts express the volume of runoff and the peak flow rate from a grass strip and the residence time in terms of the size and surface and subsurface characteristics of the grass strip as well as the size and surface characteristics of the area draining to the filter strip. These charts are developed by using a mathematical model based on a kinematic‐wave formulation of overland flow and Green‐and‐Ampt formulation for infiltration. The results are obtained in terms of dimensionless parameters and generalised through the principle of hydrologic similarity. An example is included to demonstrate the use of the charts in a practical design problem.
XRP Network and Proposal of Flow Index

XRP is a modern crypto-asset (crypto-currency) developed by Ripple Labs, which has been increasing its financial presence. We study its transaction history available as ledger data. An analysis of its basic statistics, correlations, and network properties are presented. Motivated by the behavior of some nodes with histories of large transactions, we propose a new index: the ``Flow Index. '' The Flow Index is a pair of indices suitable for characterizing transaction frequencies as a source and destination of a node. Using this Flow Index, we study the global structure of the XRP network and construct bow-tie/walnut structure.
Moderating reference group and message framing influences on sustainable surplus food consumption advertising appeals

ABSTRACT This paper examines how injunctive, descriptive, and benefit appeals encourage consumers to engage in unfamiliar ‘sustainable behaviours’ – specifically, the consumption of surplus food, defined as edible foods that are never sold to or consumed by targeted customers. Three experiments involving 815 participants were run to assess reference group and message framing types as moderators of advertising appeal influence. Results indicate a significant interactive effect between reference group and advertising appeal on sustainable food consumption practices. For descriptive appeals, membership groups were the most effective for promoting sustainable food consumption; for injunctive and benefit appeals, aspirational groups were the most effective. Interaction between advertising appeal and message framing also exerted a significant effect on sustainable food consumption behaviours, with descriptive and benefit appeals the most effective when used with positive message framing, and injunctive appeals the most effective when used with negative message framing.
An RNS to binary converter in a three moduli set with common factors

This paper describes a residue number to binary converter that converts numbers in the moduli set 2n+2, 2n+1, 2n with 2 as a common factor. An algorithm and a hardware implementation for the converter are proposed. The hardware implementation uses Chinese Remainder Theorem (CRT) and this has been made possible by mapping the moduli set into a pairwise relatively prime integers to satisfy CRT requirements. Properties of modular arithmetic are used to reduce the complexity of the multipliers in the proposed hardware. The converter does not use any explicit module operation in the evaluation as is normally done in implementations that use CRT. >
PZT‐Based Piezoelectric MEMS Technology

This review article presents recent advancements in the design and fabrication of thin-film (<3 μm) lead zirconate titanate (PZT) microelectromechanical system (MEMS) devices. The article covers techniques for optimizing highly (001)/(100) oriented chemical solution deposited PZT films to achieve improved piezoelectric coefficients. These PZT films combined with surface and bulk micromachining techniques are fabricated into actuators and transducers for radio frequency (RF) switches, nanomechanical logic, resonators, and power transformers for use in communication systems and phased-array radar. In addition, the large relative displacements generated by PZT thin films have been used to demonstrate mechanical mobility in MEMS devices, including insect-inspired flight actuators and ultrasonic traveling wave motors. In conjunction with actuation, PZT films are being developed for feedback sensors for the integrated control of insect-inspired robots.
The Relative Prevalence Of Common Behavioral And Emotional Disorders In Children

Aim: The study aimed to assess the relative prevalence of common behavioral and emotional disorders in children reporting in a psychiatric clinic. Materials & Methods: The study was primarily focused on pediatric patients those reported for different psychiatric issues in post Covid phase. All studied children were screened first for basic parameters of Covid and related symptoms. Detailed case history was recorded and any sign of behavioral and emotional disorders were explored. The study was completed within 4 months wherein total 12 pediatric patients had been studied for the predefined objectives. Signs and symptoms of common behavioral and emotional disorders were identified and categorized for further assessments. Statistical Analysis and Results: Statistical analysis was done by statistical software Statistical Package for the Social Sciences (SPSS). P ≤ 0.05 was considered as statistically significant. Total 7 male and 5 female subjects were studied in this study. Therefore, majority of the studied patients were male. First age group of 5-6 years had minimum patients (1). 3 children were reported in the third, fourth and fifth age groups (each). Age range of 13-14 years had higher prevalence of the behavioral and emotional disorders. In age range of 5-6 years, only one child reported confirmed for anxiety. Conclusion: The prevalence of emotional obsessive compulsive disorder, anxiety and ADHD was relatively higher in studied subjects. The reported disorders showed a rising pattern with growing age.
The Materiality of Corporate Governance Report Disclosures : Investigating the Perceptions of External Auditors working in Egypt

This study investigates the external auditors working in Egypt perceptions regarding the materiality of the corporate governance report (CGR) disclosures. All external auditors working in Egypt were surveyed to determine whether disclosures are materially important to this group while they are performing their audits. The final sample consists of 247 auditors who work in Big 4 auditing firm, private auditing firms affiliated to foreign auditing firms, private auditing firm not affiliated to foreign auditing firm and governmental auditors. Through hypotheses testing the main findings reveal that all external auditors perceive CGR disclosures as materially important. Moreover, there was significant difference in some of their perceptions, these differences were explained through psychological engagement (i.e., experience, educational level, and work exposure) throughout the analysis. The findings show that respondents consider information related to internal control, governance and compliance to laws and regulations to be significantly material in auditing decision. While information regarding transparency and disclosure were the less important when compared to other sections of the CGR. The current study extends and enriches the ongoing academic and practical debate on the usefulness of narrative disclosures. The study findings suggest that regulators should seek more communications to the current requirements as the results shows that direct knowledge of the auditors made a big difference in their perceptions. The current investigation touched a blind spot in the literature and provided evidence for the materiality level of CGR disclosure in auditing decision, as previous studies investigated how governance report affect the firm value.
An Empirical Study on E-government Adoption in Vietnam: Moderating Role of Uncertainty Avoidance *

With the aims to improve government productivity and meet the citizens’ requirements, E-government has gained incredible popularity in many nations worldwide. Vietnam has established an E-government to enhance the quality of its public services for many years. Exploring factors affecting E-government adoption in Vietnam has drawn significant attention from many scholars; however, considering the effect of national culture in general, especially the uncertainty avoidance dimension, is still a shortage of studies. Therefore, based on the UTAUT model, this study explores the determinants of usage behavior and the moderating role of uncertainty avoidance dimension to usage behavior of citizens in E-government services in Vietnam. The results show that performance expectancy, effort expectancy, social influence have significant impacts on behavioral intention toward E-government usage behavior, and facilitating conditions play an essential role in forming E-government usage behavior. Moreover, uncertainty avoidance was found to be a moderator to the relationship between social influence and behavioral intention to use E-government.
Towards Efficient and Effective Adversarial Training

The vulnerability of Deep Neural Networks to adversarial attacks has spurred immense interest towards improving their robustness. However, present state-of-the-art adversarial defenses involve the use of 10-step adversaries during training, which renders them computationally infeasible for application to large-scale datasets. While the recent single-step defenses show promising direction, their robustness is not on par with multi-step training methods. In this work, we bridge this performance gap by introducing a novel Nuclear-Norm regularizer on network predictions to enforce function smoothing in the vicinity of data samples. While prior works consider each data sample independently, the proposed regularizer uses the joint statistics of adversarial samples across a training minibatch to enhance optimization during both attack generation and training, obtaining state-of-the-art results amongst efﬁcient defenses. We achieve further gains by incorporating exponential averaging of network weights over training iterations. We ﬁnally introduce a Hybrid training approach that combines the effectiveness of a two-step variant of the proposed defense with the efﬁciency of a single-step defense. We demonstrate superior results when compared to multi-step defenses such as TRADES and PGD-AT as well, at a signiﬁcantly lower computational cost.

Production of Single- Cell Protein from some Fruit peels

The bioconversion of various wastes such as fruit peels into some valuable products such as single-cell protein (SCP) has simultaneous potential to resolve nutritional protein deficiency worldwide. The shortage by obtaining an economical product for food and feed, as well as the mitigation of environmental pollutants to a large extent through the optimization of these residues, which serve as substrates for the production of a product with a high nutritional value. Therefore, the current study aimed to evaluate the feasibility of using fruit peels such as orange peel and pomegranate and their mixture through chemical treatment concentrations of dilute hydrochloric acid as well as thermal treatment by autoclave to obtain the highest concentration of sugars needed for yeast growth and the evaluation of biomass yields as a single-cell protein (SCP). The results showed that orange and pomegranate peels treated with different concentrations of 10, 20 and 30% hydrochloric acid had the highest yield of reducing sugars )4.89g/100g peel) obtained from orange peels treated with 10% acid concentration. After that, a comparison was made between the treatment with the best concentration of acid (HCl 10%) and the thermal treatment by autoclaving for orange peels, pomegranate peels and a mixture of them, so the treatment with acid (HCl 10%) for the mixture had the highest concentration of reducing sugars, followed by orange peels (5.90 and 4.87g/100g peels) respectively. But it was found that this treatment affects the growth of Saccharomyces cerevisiae later compared to the thermal treatment. After that, the media were prepared from orange peels and pomegranate peels, mixed with acid (HCl 10%) and heat treatment, and salts were added to one of them and the other without salts. The results were in favor of the thermal treatment. The orange peels thermal treated without salts gave the largest amount of protein, followed by the mixture without salts, then the mixture with salts that were thermal treated (9.39, 8.107 and 8.02 g/L) respectively.
Optimization of a Leading Edge Groove Tilting Pad Journal Bearing for Application in a Small, High Speed, Multi-Stage Steam Turbine

Optimization of a leading edge groove tilting pad journal bearing for application in a small, high speed, multi-stage steam turbine is described. Rotordynamics constraints to meet a design objective maximum operating speed of 18,000 rpm resulted in a rotor with a 5 1. 0 in. bearing span and 5. 0 in. diameter tilting pod journal bearings. This configuration yielded a design with projected bearing loads of less than 25 psi, and journal surface speeds that could approach 400 ft. /sec. Under these conditions, the applicable limits of conventional style tilting pad journal bearings are stretched, since operation is well into the turbulent flow regime. This can result in significantly higher than predicted operating pad temperatures and increased frictional losses. Furthermore, at very light pad loads, bearing dynamic performance and influence on rotor behavior often does not correlate well with theory. For this application, high efficiency leading edge groove bearings (journal and thrust) were used, due to their preferred steady state operating characteristics at high speed. However, as is often observed with lightly loaded conventional style journal bearings, dynamic performance did not precisely match that predicted by theory. This was investigated by profiling the exit side of the leading edge groove with both a tapered and, pocket geometry. Two case histories are presented demonstrating their effect on rotorbearing stability and unbalance response. The modified bearings yielded greater system stability at high speeds, reduced overall vibration amplitudes, and significantly improved effective shaft damping on passing through the rotor's first peak response speed.
A Contribution to the Frequency Analysis and Transient Response of Power Transformer Windings

Abstract—This article proposes a new approach to study the frequency response and the transient analysis of power transformer windings. For improved accuracy, the suggested model includes, among other equivalent circuit elements, the mutual magnetic couplings between any winding turn and all others. This implies that the equivalent inductance of any considered turn will be a location-dependent parameter. Accordingly, the winding will be analyzed as a non-uniform transmission line. Through the application of a recursive circuit reduction technique, a closed-form Laplace s-domain analytical expression for the winding's input impedance can be obtained for any neutral treatment. The resulting expression can be used to determine the winding's series and parallel resonance frequencies. The s-domain expression for the input impedance, in connection with the numerical inverse Laplace transform, will be utilized for determination of the winding's time-domain transient response for any input voltage or current time waveform. Accuracy increases with the assumed number of winding sections, which can be even increased to the actual number of turns, limited only by the available computation resources. The results of case studies are in good agreement with those available in the literature using the time-domain solution of the simultaneous differential equations in the state variables.
Exploring the clinical utility of an electronic diary in fibromyalgia patients: A pilot study

This study examines the clinical utility of an electronic diary (ED) in the monitoring of the clinical manifestations of fibromyalgia (FM), compared to traditional paper-pencil self-reports. Fourteen women with FM completed an interview, several questionnaires, and an ED for a week (several times a day) recording pain, fatigue, sleep, difficulty in thinking, emotional distress, difficulty in daily functioning, coping with the disease, and stress. There were no differences in symptoms throughout the different moments of the day. A sleep latency of 45.36 minutes and sleep duration of 6.25 hours was observed. Significant correlations were found between ED measures depending on the time of day, and between ED measures and questionnaires. The ED showed to be useful for the evaluation of FM symptomatology and could be a key component in psychological intervention programs.
