parental involvement

This paper provides an in-depth analysis of a series of 3 large-scale quantitative data collection activities in Hungary. The data collection took place in November 2020, and in April and October-November 2021 with 14762, 26851 and 18451 respondents respectively. Survey questions were exploring parents personal experiences with the virus itself (having been infected, knowing somebody infected, etc.) and its impact on their views on school closures and other restrictions such as mask-wearing, ban of extracurricular activities, ban on parents entering schools, vaccination of teachers and children, their necessity and parents’ views on associated risks. As data collection also provided demographic information on the age, profession and place of living of respondents, analysis could also focus on the impact of these factors on parents’ views. It was especially interesting to analyse the impact of working in sectors bearing the burden of both infections and closures, namely health care, retail, public transport and education itself. The data collection was conducted through online surveys linked to the e-mail addresses of members of the Hungarian national parents association, ESZME. Since the respondents of the different surveys were different, this should be considered to be a series of cross-sectional survey research. Data analysis was conducted using the tool Tableau. There was an analysis of each survey separately, and a comparative analysis was also conducted, especially to see how more personal experiences with the virus impacted the views of parents.
Lower extremity response of the Thor-LX compared to the Hybrid-III lower leg in frontal barrier crash tests

The Thor-Lx leg and foot complex is being developed by the National Highway Traffic Safety Administration (NHTSA), the Applied Safety Technologies Corporation, and GESAC, Inc. as a new research and development (R&D) tool which will be more biofidelic than the current Hybrid-III lower extremity. This paper reviews the results from a matrix of tests performed to evaluate the response of the Thor-Lx in comparison to the Hybrid-III lower extremity in high-speed frontal crashes. The testing included three 64 km/h frontal offset deformable barrier tests and two 56 km/h flat rigid barrier tests. Testing was done using the following Anthropomorphic Test Device (ATD) combinations: Hybrid-III with the Hybrid-III Enhanced Instrumented Tibia, Hybrid-III with the Thor-Lx, and Thor with the Thor-Lx. The response of the lower extremity was found to vary with each leg and torso combination. Tibia bending moments were reduced and the lower tibia axial compressive force was increased in the Thor-Lx when compared to the Hybrid-III tibia. This phenomenon is attributed to the Achilles' tendon added to the Thor-Lx. When the Thor torso was used, loads measured in the lower extremity were lower than when the Hybrid-III torso was used. This lower level of loading is a result of changes in the torso kinematics that reduce the forward stroke of the pelvis.
TWELFTH RANKINE LECTURE OF THE BRITISH GEOTECHNICAL SOCIETY: "THE RELEVANCE OF SOIL FABRIC TO SITE INVESTIGATION PRACTICE"

DATA ARE COLLECTED FROM 35 SITES WHERE THE FABRIC OF CLAY SOILS IS RELATED TO LABORATORY AND FIELD BEHAVIOR. THE SITESARE CHOSEN TO RANGE OVER THE GEOLOGICAL SERIES FROM RECENT TO ORDOVICIAN TIME AND TO INCLUDE APPLICATIONS TO DAMS, ROAD EMBANKMENTS CUTS, RETAINING WALLS, FOUNDATIONS, AND CULVERTS. THE CASES ILLUSTRATE THE INADEQUACY OF CONVENTIONAL SITE INVESTIGATION PROCEDURE FOR MAJOR CIVIL ENGINEERING PROJECTS WITH RESPECT TO THE RELEVENT PROPERTIES OF NATURAL FOUNDATION STRATA. IT IS SHOWN TO BE ESSENTIAL FIRST TO EXAMINE, DESCRIBE AND RECORD THE FABRICS OF CONSECUTIVE SOIL SAMPLES AND IF SAMPLING IS RELEVENT TO USE THE KNOWLEDGE OF THE OVERALL GEOLOGY, FABRIC DETAILS, AND WATER LEVELS IN RELATION TO THE ENGINEERING PROBLEM TO DECIDE THE LOCATION, QUALITY AND SIZE OF SPECIMENS FOR ELEMENT AND MODEL TESTS. THE QUALITY AND SIZE OF SPECIMENS INFLUENCE THE DRILLING TECHNIQUE. BRIEF MENTION IS MADE OF CONSECUTIVE AND CONTINUOUS SAMPLING, OF STEREO PHOTOMACROGRAPHIC TECHNIQUE, OF EQUIPMENT FOR SAMPLING AND TESTING 250 MM DIAMETER SPECIMENS, AND OF A CENTRIFUGE LARGE ENOUGH TO ACCEPT MODELS REPRESENTATIVE OF A NATURAL FABRIC. THE PROPOSALS, WHICH ARE REVIEWED IN THE LIGHT OF EARLIER WORK OF HVORSLEV, HARTING, TERZAGHI AND PECK, ARE ADAPTABLE TO THE CLASS OF INVESTIGATION APPROPRIATE TO THE PROBLEM. IN CONSIDERING THE RELATION BETWEEN INVESTIGATING THE GEOLOGY AND THE AVAILABLE FINANCE, FINANCIAL ARRANGEMENTS WHICH AVOID OVERALL COMPETITIVE TENDERING FOR SITE INVESTIGATIONS ARE CONSIDERED TO BE ESSENTIAL IF IMPROVEMENTS IN THE QUALITY OF SITE REPORTS ARE TO BE ACHIEVED. /AUTHOR/
Demonstration, Qualification, and Airworthiness Certification of Structural Damage Sensing (SDS) Systems for Air Force Application

Abstract : Structural Health Monitoring (SHM) sensor systems have gained much interest in the aerospace community as potentially enabling technologies for reducing maintenance costs while maintaining flight safety of aging structures. Many candidate SHM technologies are essentially damage detection systems, i.e. variations of well-established NDI methods such as ultrasonics, electro-magnetic (eddy current), and acoustic emission. Still others employ displacement detection such as strain-sensing and dynamic vibration sensing. Unfortunately, the path for transition onto United States Air Force (USAF) weapon systems is not well defined. Before SHM technologies can be qualified for fleet-wide usage, these systems must demonstrate their capability to meet performance requirements in terms of detection capability, reliability, and safety while and providing an economic benefit. Ultimately the qualification program must be sufficiently robust to support an airworthiness certification decision. This document provides guidance for the demonstration and qualification of permanently mounted damage detection systems intended for use on USAF aircraft. More specifically, this document will a) focus on applications where damage tolerance principles are used to manage structural integrity, b) propose a task-based approach for system qualification, and c) identify existing Air Force policies that define the path for modification management and obtaining airworthiness certification approval.
Effects of Herbst Appliance Treatment on the Mandibular Incisor Segment: A 3-D Analysis

Background: Three-dimensionally evaluation of the treatment changes of a Herbst appliance using a lower anchorage unit not touching the lingual surface of the lower incisors. Methods: 23 Class II:1 patients (12 males, 11 females) with a mean age of 15.7±1.7 years treated with a Flip-Lock Herbst® (TP Orthodontics, Inc., La Porte, IN, USA) appliance. The lower anchorage unit for the Herbst appliance consisted of two anchor bands connected by a lingual arch with 3mm distance from the incisor’s lingual surface. Treatment changes in mandibular incisor inclination, overjet and overbite were evaluated by means of cone beam computed tomography images (i-CAT® Classic unit, Imaging Sciences International, Hatfield, PA, USA) obtained before and after treatment with the Herbst appliance. Results: On average, there was a statistically significant increase in mandibular incisor inclination (2.6+1.8°) and a reduction in overjet (3.2+2.2mm) and overbite (1.3+0.9mm). Genders did not differ significantly. Incisor proclination was however only seen in 74% of the patients. The changes in mandibular incisor inclination were associated with the changes in overjet (/r/ = 0.1 to 0.5) and overbite (/r/ = 0.3 to 0.7). Conclusion: A Herbst appliance with a mandibular anchorage unit distant from the incisor’s lingual surface results in smaller amounts of mandibular incisor proclination compared to literature. However, as it induces canine anchorage loss, the decreased amount of proclination may not prevail after multibracket treatment. Trial registration: This study was registered 08 February 2011, reviewed and approved by the Ethics Committee of Araraquara Dental School, Paulista State University (FOAr-UNESP), project number 62/2010. https://www.foar. unesp.br/#! /comissoes-e-comites/cep/
Various metal extraction from hydrochloric acid into n-dodecane by methylimino-dioctylacetamide (MIDOA)

ABSTRACT Methylimino-di-n-octylacetamide (MIDOA) was used to extract 57 metals from HCl into n-dodecane. MIDOA is a tridentate ligand with one N donor and two carbonyl O donors and can extract soft acid metals and metal oxonium anions. In the present work, Fe(III), Zr(IV), Ga(III), Mo(VI), Tc(VII), Pd(II), Cd(II), In(III), Sn(IV), W(VI), Re(VII), Os(III), Ir(III), Pt(IV), Au(III), Hg(II), Bi(III), and U(VI) had distribution ratios above 10 when using 0.1 M MIDOA/n-dodecane and 3 M HCl. The amount of metal ion (Mo(VI), Tc(VII), Re(VII), Pd(II), Pt(IV), and Au(III)) extracted from HCl was greater than that obtained using HNO3.
Evaluation of remotely piloted aircraft in surveying applications

Over recent years Remotely Piloted Aircraft (RPA) have become highly accessible to civilians. This presents many significant opportunities to surveyors, by giving them the chance to combine the science of photogrammetry with a personal, portable and self-piloted aerial platform. But despite the obvious opportunities, many questions still linger. It must be remembered that this technology is vastly different from the technologies that are currently at most surveyor’s disposal, i.e. GNSS, total stations, laser scanners, and LiDAR. RPA are accompanied by a range of unique considerations. How fast and how far can they fly? What weather conditions can they operate in? What are the laws and regulations involved? And most importantly, how does all this impact on how they can be used for surveying? The aim of this project was to answer these questions by evaluating the performance of an RPA after using it for a survey. First, an evaluation plan is outlined that is focused on determining the overall practicality of using an RPA in a specific surveying application—in this case, the determination of coal stockpile volumes. Several evaluation criteria are specified: efficiency, accuracy, usability and legal requirements. An RPA is used to survey a coal stockpile area and its performance is analyzed using the evaluation plan. The accuracy of the resulting DTM, and the efficiency of the RPA is analysed by comparing its results, against the results of the same survey performed with a terrestrial laser scanner (TLS). Usability is also assessed on a comparative basis with the TLS, using the system usability scale (SUS). The relevant statutory regulations are also studied and the impact of these regulations upon surveying activities is explained. The results show that the RPA is more than suitable for coal stockpile surveys. Accuracy and efficiency are comparable with that of a TLS, however the most significant benefits are those which have not been quantified—those being the significantly enhanced job safety; significantly reduced physical labor requirements and a greatly simplified workflow. Although these results satisfy the aim of the project, it is recognized that the results can be improved by altering the evaluation criteria or process, or by taking an entirely new approach. A number of suggestions are discussed and included as recommendations for future research.
FLUCTUATIONS AND GROWTH IN RAGNAR FRISCH’S ROCKING HORSE MODEL

Ragnar Frisch’s famous “rocking horse” model has been the object of much praise and even controversy since its publication in 1933. This paper offers a new simulation of the model to show that there exist cyclical trajectories in the propagation mechanism. By building an analytical solution taking the same form as Frisch’s original solution, we can provide new insights into the ideas encapsulated in his model, in particular the fact that the author constructed a model combining cycles and growth. The exploration of Frisch’s formal construction of the model leads us to link his statistical work on the decomposition of time series with his economic insights on investment cycles, which both led to the 1933 model. We contrast Frisch’s approach to that of other econometricians who used similar equations, showing that their different mathematical solutions were the product of what they wanted to show with their models.
Lactoperoxidase inhibition by tautomeric propylthiouracils

Lactoperoxidase (LPO) enzyme inhibition by tautomeric propylthiouracil (PTU) structures have been investigated in this work based on the in silico methodologies. Six possible PTU structures have been optimized to obtain their energy-minimized structures based on quantum mechanics computations. Afterwards, their interactions with LPO enzyme have been evaluated based on molecular docking simulations. The results indicated that the structural changes of PTU analogues could perturbate the interaction properties, in which it could be seen by either the magnitudes of binding energies or the types of interacting amino acids. In this work, the original thio-keto structure of PTU showed better interaction properties with LPO enzyme; however, the properties for other PTU derivatives have been deviated from this reference model. It is known that the tautomerism is common for biological structures; therefore, exploring their arisen effects on the structural properties and activities could reveal insightful information for judging their potency and efficacy.

Integrated methodologies based on structural health monitoring for the protection of cultural heritage buildings

In the last decades the need for an effective seismic protection and vulnerability reduction of strategic structures and particularly the architectural heritage determined a growing interest in Structural Health Monitoring (SHM) as a measure of passive mitigation of earthquake effects. The object of monitoring is to identify, locate and classify type and severity of damages induced by external actions or degradation phenomena and to assess their effects on the structural performance. In this way it is possible to take appropriate measures to reduce the danger of collapse and, when necessary, perform strengthening interventions to improve the structural and seismic capacity. Motivated by the above reasons, this thesis aims at providing a contribution to the development of techniques and integrated methodologies, based on SHM, for the assessment and protection of Cultural Heritage (CH) buildings and monuments. Firstly, after a detailed state of the art review on specific topics related to SHM of civil engineering structures, a new methodology for the implementation of monitoring techniques on historic masonry structures is proposed. Selected case studies, equipped with distributed sensors and acquisition systems, allowed the definition and successive validation of SHM as a knowledge-based assessment tool, implemented to evaluate intervention needs, following an incremental approach during their execution, and to control the damage states of buildings in a post-seismic scenario. In order to maximize the benefits of SHM and optimize the entire process, dedicated software for static monitoring and automated algorithms for modal parameters identification have been developed, able to provide almost real time information on the health state of the monitored structure. Finally integrated procedures based on robust statistical and numerical models have been implemented to interpret and exploit SHM outputs to assess the structural conditions of the investigated CH buildings.
The Ownership Structure Influence on the Dividend Distribution Policy: The Case of Listed French Family Firms

The usefulness and justification of corporate dividend distribution policies are among the most controversial topics in financial theory. This research aims to shed light on this issue by studying the case of French listed family firms. These companies have a specific governance structure that influences the dividend distribution policy. We examined the impact of the family ownership structure on dividend distribution policy and present empirical study results for a sample of listed French family companies. We explain the dividend distribution policy through the family shareholding structure and the presence of institutional investors and their possible influence. The theoretical framework is the agency relationship. The results show that family ownership positively affects dividend distribution; however, institutional investors have a negative influence.
Empowering Agent for Oklahoma School Learning Communities: An Examination of the Oklahoma Library Improvement Program

The purposes of this study were to determine the initial impact of the Oklahoma Library Media Improvement Grants on Oklahoma school library media programs; assess whether the Oklahoma Library Media Improvement Grants continue to contribute to Oklahoma school learning communities; and examine possible relationships between school library media programs and student academic success. It also seeks to document the history of the Oklahoma Library Media Improvement Program 1978 - 1994 and increase awareness of its influence upon the Oklahoma school library media programs. Methods of data collection included: examining Oklahoma Library Media Improvement Program archival materials; sending a survey to 1703 school principals in Oklahoma; and interviewing Oklahoma Library Media Improvement Program participants. Data collection took place over a one year period. Data analyses were conducted in three primary phases: descriptive statistics and frequencies were disaggregated to examine mean scores as they related to money spent on school library media programs; opinions of school library media programs; and possible relationships between school library media programs and student academic achievement. Analysis of variance was used in the second phase of data analysis to determine if any variation between means was significant as related to Oklahoma Library Improvement Grants, time spent in the library media center by library media specialists, principal gender, opinions of library media programs, student achievement indicators, and the region of the state in which the respondent was located. The third phase of data analysis compared longitudinal data collected in the 2000 survey with past data. The primary results indicated students in Oklahoma from schools with a centralized library media center, served by a full-time library media specialist, and the school having received one or more Library Media Improvement Grants scored significantly higher academically than students in schools not having a centralized library media center, not served by a full-time library media specialist, and the school not having received one or more Library Media Improvement Grants. Students in schools having even one of these components scored higher academically than students in schools with none of these components.
A recommended earthquake response spectrum model for Australia

Abstract Response spectrum provisions in the current Australian Earthquake Loading Standard (AS1170.4) were based on recommendations from the 1991 edition of the Uniform Building Code for the United States. Since the implementation of AS1170.4 in 1993 there have been significant developments internationally and in Australia in the area of response spectrum modelling on both rock and soil sites. In this paper, a new normalised design response spectrum is recommended for rock sites in Australia based on a response spectral velocity of 1.8 times the peak ground velocity, and corner periods of T1=0.35secs and T2=1.5secs (based on a magnitude 7 earthquake event). The recommended rock response spectra for 500 year return period is generally consistent with the AS1170.4 spectrum in the low period range, however, more accurately represents the displacement demand expected in the higher period range. Recommendations for the development of response spectra for soil sites have also been presented in ADRS format for use with the capacity spectrum method, to assess the seismic performance of new and existing structures in Australia. A brief introduction to the method has been presented in the paper.

Intervertebral foramen injection of plerixafor attenuates CCD-induced low back pain in rats through down-regulation of Nav1.8 and Nav1.9

BackgroundLow back pain, an extremely common chronic pain, is now the number one cause of disability globally. On the chronic compression of the dorsal root ganglion (CCD) model, a typical low back pain model, previous study has discovered that C-X-C chemokine receptor type 4 (CXCR4) involved in mediating low back pain. However, the underlying molecular mechanisms and whether it has the potential to serve as an applicable target for clinical treatment of low back pain remains unclear. MethodsCCD-induced low back pain model was established by inserting stainless steel L-shape rod into the intervertebral foramen at L5 level. Multiple pain behaviors including mechanical hyperalgesia and allodynia, thermal hyperalgesia and cold allodynia were evaluated. The role of CXCR4 in CCD-induced pain was assessed by intraganglionar CXCR4 siRNA injection and intervertebral foramen injection of plerixafor, a selective CXCR4 antagonist. The expression change of CXCR4, Nav1.8 and Nav1.9 was examined by immunofluorescent staining.ResultsWe showed that the CXCR4 were dramatically up-regulated in the compressed dorsal root ganglion (DRG) neurons in CCD model, and intraganglionar CXCR4 siRNA injection significantly reduced CCD-induced multiple pain behaviors, including mechanical hyperalgesia and allodynia, thermal hyperalgesia and cold allodynia. The expression of Nav1.8 and Nav1.9 in the compressed DRG were also enhanced after CCD, and which were remarkably reversed by intervertebral foramen injection of plerixafor at the compression level. Moreover, intervertebral foramen injection at the compression level of plerixafor and ropivacaine as well as A-803467, a Nav1.8 selective blocker, were all able to reverse CCD-induced multiple pain behaviors. However, the analgesic duration of plerixafor maintained at least for 24 h which was much longer than that of A-803467 and ropivacaine. Finally, we found intervertebral foramen injection of plerixafor at the adjacent non-compression level has no effect on CCD-induced pain and intervertebral foramen injection of plerixafor in normal rats did not affect their basal pain sensitivity.ConclusionsOur study provides evidence that CXCR4-Nav1.8/Nav1.9 axis in compressed DRG contributed to CCD-induced low back pain and intervertebral foramen injection of plerixafor was a potential and applicable therapeutic strategy for the treatment of low back pain.
