Mothers’ Experiences of Supporting Adolescent Children Through Long-Term Treatment for Substance Use Disorder
Authors: Smith Jacqueline M. , Estefan Andrew , Caine Vera
Published: December 2017

Substance use disorder is a complex phenomenon that affects people in many different contexts. Adolescent substance abuse within families is a particular problem that merits ongoing study. In particular, the experiences of mothers in this context are not fully explored. In this narrative inquiry study, we explored the experiences of four mothers parenting children through long-term substance abuse treatment. Participants were recruited from a family-orientated long-term adolescent treatment center in Alberta, Canada. The mothers’ experiences were explored within a three-dimensional narrative inquiry space of temporal, social, and situated experience. Four narrative accounts were co-composed, revealing personal, familial, social, and substance abuse–related complexities in mothers’ experiences. Four narrative threads were also theorized: navigating complexities; loud silences; places, spaces, and the in-between; and living within one another’s stories. These narrative threads are discussed in relation to health and social care practices. Recommendations for practice and research are made.
Concurrent multi-scale fatigue damage evolution simulation method for long-span steel bridges
Authors: Sun Bin , Xu You-Lin , Zhu Qing , Li Zhaoxia
Published: December 2017

Fatigue damage is one of the leading causes for structural failure of long-span steel bridges, but fatigue damage evolution of a long-span steel bridge is very complex. This study proposes a concurrent multi-scale fatigue damage evolution simulation method for long-span steel bridges from micro short crack nucleation and growth to macro structural component damage until mega structural failure. As a case study, the fatigue damage evolution of the Stonecutters Bridge in Hong Kong under cyclic vehicle loading is finally simulated using the proposed method. It shows that the proposed method is computationally feasible even for such a large scale structure. The method can provide a clear picture how micro short cracks grow into macro fatigue damage of structural components and eventually lead to mega structural failure.

Published: December 2017

Background:

Sarcopenia, reduced skeletal muscle mass, is associated with frailty, injuries, and mortality. The purpose of this study was to evaluate the impact of computed tomography–determined sarcopenia on surgical complications and outcomes after resection of non-small cell lung cancer.

Methods:

For a total 272 non-small cell lung cancer patients that underwent surgery between 2011 and 2016, cross-sectional area of muscle at the third lumbar vertebra (L3) was retrospectively measured using preoperative chest computed tomography images. Sarcopenia was defined as an L3 muscle index of <55 cm2/m2 for men and of <39 cm2/m2 for women. Clinical characteristics, postoperative complications, disease-free survival, and overall survival of patients with or without sarcopenia were compared.

Results:

A total of 60.3% ( n = 164) were male, and mean patient age was 62.9 ± 9.6 years. The prevalence of sarcopenia was 22.4% for all study subjects, 32.9% for men, and 6.5% for women. No significant difference was observed between patients with or without sarcopenia in terms of intensive care unit or hospital stay ( p = 0.502 and p = 0.378, respectively), and the presence of sarcopenia was not associated with postoperative complications. Furthermore, no significant difference was observed between the 3-year disease-free survival rate (74.3% vs 66.7%, p = 0.639) or 3-year overall survival rate (83.9% vs 87.7%, p = 0.563) of patients with or without sarcopenia.

Conclusion:

Sarcopenia as determined by preoperative computed tomography does not appear to have a negative impact on surgical outcome or overall survival for resected non-small cell lung cancer patients.
Hotel room attendants’ delivery of quality service
Authors: Kensbock Sandra L , Patiar Anoop , Jennings Gayle
Published: December 2017

Illuminating the physical difficulties experienced by hotel room attendants in delivering service quality at five-star hotels on the Gold Coast region of South East Queensland, Australia, our research was founded on socialist-feminist and critical theory epistemologies. In-depth interviews were conducted with a sample of 46 hotel room attendants. We used a qualitative, social-constructivist, grounded theory methodology to render the empirical material into a basic social structural process of tasking. Tasking offers a conceptual framework of room attendants’ daily employment experiences as they transform hotel rooms to prescribed standards. Tasking illustrates the high physical demands placed on room attendants, tantamount to exploitation from their own perspectives. Tasking contributes to research on employment experiences in hospitality, particularly on hotel praxis, delivery of quality customer service and the operational demands placed on room attendants. This paper presents the results of the first in-depth examination of the daily functions and roles of hotel room attendants.

Published: December 2017

Sensory processing problems and related dysfunctions are among the most common conditions in children with autism spectrum disorder (ASD). This study examined the effect of sensory integration therapy (SIT) on different aspects of occupational performance in children with ASD. The study was conducted on an intervention group ( n = 16) receiving SIT and a control group ( n = 15) with 3- to 8-year-old children with ASD. The Short Child Occupational Profile (SCOPE) was used to compare the two groups in terms of the changes in their occupational performance and the Sensory Profile (SP) was used to assess sensory problems. The intervention group showed significantly greater improvement in all the SCOPE domains, as well as in all the SP domains, except for the “emotional reactions” and “emotional/social responses” domains, ( p < .05). The effectiveness of SIT in improving occupational performance in children with ASD as a health-related factor is supported by our findings.
Bypass flow in small absorber sphere channels of the high-temperature gas-cooled reactor pebble-bed module
Authors: Liu Ziping , Li Zeguang , Sun Jun
Published: December 2017

In the high-temperature gas-cooled reactor pebble-bed module, the helium bypass flow among graphite blocks cannot be ignored due to its effect on the temperature distribution as well as the maximum temperature in the reactor core. Bypass flow was previously analyzed in the discharging tube, in vertical gaps between graphite reflectors, and in control rod channels. The focus of this study is on the bypass flow that connects the small absorber sphere channels. Different from bypass flow connecting the control rod channels, there was no evident inlet or outlet flow paths into or out of the small absorber sphere channels at the top or bottom of the reactor core. Therefore, the bypass flow connecting the pebble bed with the small absorber sphere channels was mainly caused by the horizontal gaps, in which those gaps would also be irregular due to installation, thermal expansion, or irradiation of the graphite reflectors. After clarifying the resistant coefficients of those gaps by computational fluid dynamic tools, the bypass flow distribution was calculated by the flow network model including the flow in the reactor core, small absorber sphere channels, as well as horizontal gaps. Cases with various size combinations of gaps were adopted into the flow network model to test the sensitivity of bypass flow distribution to those parameters. Finally, the bypass flow in the small absorber sphere channels was concluded to be not significant in the reactor core.

Published: December 2017

Endothelial dysfunction is a major player in the development and progression of vascular pathology in pulmonary arterial hypertension (PAH), a disease associated with small vessel loss and obstructive vasculopathy that leads to increased pulmonary vascular resistance, subsequent right heart failure, and premature death. Over the past ten years, there has been tremendous progress in our understanding of pulmonary endothelial biology as it pertains to the genetic and molecular mechanisms that orchestrate the endothelial response to direct or indirect injury, and how their dysregulation can contribute to the pathogenesis of PAH. As one of the major topics included in the 2017 Grover Conference Series, discussion centered on recent developments in four areas of pulmonary endothelial biology: (1) angiogenesis; (2) endothelial‐mesenchymal transition (EndMT); (3) epigenetics; and (4) biology of voltage‐gated ion channels. The present review will summarize the content of these discussions and provide a perspective on the most promising aspects of endothelial dysfunction that may be amenable for therapeutic development.

Published: December 2017

Acute respiratory distress syndrome (ARDS) is a diffuse lung injury that leads to a severe acute respiratory failure. Traditional diagnostic criteria for pulmonary hypertension (PH), in this situation, may be unreliable due to the effects of positive pressure ventilation and vasoactive agents. The aim of this study is to describe the hemodynamic characteristics of PH secondary to ARDS, in relation with respiratory parameters. We assessed the hemodynamic, respiratory function, and ventilator parameters in a cohort of 38 individuals with ARDS‐associated PH defined by mean pulmonary arterial pressure (mPAP) ≥ 25 mmHg. Individual characteristics: PaO2/FiO2 = 110 ± 60 mmHg, alveolar‐arterial oxygen gradient (A‐aO2) = 549 ± 148.9 mmHg, positive end‐expiratory pressure (PEEP) = 8.7 ± 3.5 cmH2O, pulmonary static compliance (Cstat) = 30 ± 12.1 L*cmH2O‐1, mPAP = 35.4 ±6.6 mmHg, pulmonary artery wedge pressure (PAWP) = 15.6 ± 5.5 mmHg, cardiac index (CI) = 3.4 ± 1.2 L/min/m2, pulmonary vascular resistance (PVR) = 3.3 ± 1.6 Wood units (WU), right atrial pressure (RAP) = 13.4 ± 5.4 mmHg, diastolic pulmonary gradient (DPG) = 12.6 ± 6.5 mmHg, and trans‐pulmonary gradient (TPG) = 19.7 ± 7.7 mmHg. The composite marker—DPG >7 mmHg and PVR > 3 WU—is associated with lower CI (P = 0.016), higher mPAP (P = 0.003), and lower pulmonary static compliance (P = 0.028). We confirmed a poor prognosis of ARDS associated with PH, with a 50% survival rate after 17 days. We observed that the survival rate at 28 days was better in the case of improvement in the PaO2/FiO2 ratio in the first 24 h (log rank P = 0.003). ARDS associated with PH is a severe condition with a very poor survival rate. The composite marker DPG > 7 mmHg and PVR > 3 WU seemed to better describe the hemodynamic and respiratory dysfunction. The improvement in PaO2/FiO2 ratio in the first 24 h defined a better survival in our cohort of patients.
Middle Eastern Rhinoplasty: Relationship of the Nasal Spine and Caudal Septum to Tip Projection and Columellar‐Labial Angle
Authors: Arden Richard L. , Baldwin Brett J. , Coffey Mary P.
Published: December 2017

Objective

To measure the anterior nasal spine length (ANSL) and septal caudal extension (SCE), as well as assess the strength of association between these variables and tip projection in the Middle Eastern nose. Our secondary aim was to assess if columellar‐labial angle (CLA) or columellar‐spinal angle (CSA) vary as a function of ANSL and/or SCE.

Study Design/Setting

Prospective single institutional study.

Subjects

Middle Eastern primary rhinoplasty patients without nasal trauma or prior endonasal surgical history.

Methods

Photographic and intraoperative caliper measurements were used to determine Goode ratio (GR), CLA, CSA, ANSL, and SCE. Associations between numeric variables were examined with scatterplots, including use of LOWESS curves and Pearson correlation coefficients. Linear regression models were used for predicting quantitative variables (GR, CLA, CSA). Logistic regression models were used for predicting overprojection status based on GR.

Results

In total, 102 patients met inclusion criteria (82 females, 20 males). Mean ANSL and SCE were 8.6 mm and 14.9 mm, respectively; ANSL and SCE had a strong positive association with each other. SCE and ANSL were found to have low predictability for GR, CLA, or CSA.

Conclusion

Determinations of projection status using the GR method do not appear to be related to ANSL or SCE values in our Middle Eastern study group. Relationships of absolute columellar‐labial or columellar‐spinal angles are likely more complex than isolated value implications of SCE or ANSL.

Published: December 2017

Hypnotics are contraindicated in obstructive sleep apnoea (OSA) because of concerns of pharyngeal muscle relaxation and delayed arousal worsening hypoxaemia. However, human data are lacking. This study aimed to determine the effects of three common hypnotics on the respiratory arousal threshold, genioglossus muscle responsiveness and upper airway collapsibility during sleep.

21 individuals with and without OSA (18–65 years) completed 84 detailed sleep studies after receiving temazepam (10 mg), zolpidem (10 mg), zopiclone (7.5 mg) and placebo on four occasions in a randomised, double-blind, placebo-controlled, crossover trial (ACTRN12612001004853).

The arousal threshold increased with zolpidem and zopicloneversusplacebo (mean±sd−18.3±10 and −19.1±9versus−14.6±7 cmH2O; p=0.02 and p<0.001) but not with temazepam (−16.8±9 cmH2O; p=0.17). Genioglossus muscle activity during stable non-REM sleep and responsiveness during airway narrowing was not different with temazepam and zopicloneversusplacebo but, paradoxically, zolpidem increased median muscle responsiveness three-fold during airway narrowing (median −0.15 (interquartile range −1.01 to −0.04)versus−0.05 (−0.29 to −0.03)% maximum EMG per cmH2O epiglottic pressure; p=0.03). The upper airway critical closing pressure did not change with any of the hypnotics.

These doses of common hypnotics have differential effects on the respiratory arousal threshold but do not reduce upper airway muscle activity or alter airway collapsibility during sleep. Rather, muscle activity increases during airway narrowing with zolpidem.
Estimating P- and S-wave inverse quality factors from observed seismic data using an attenuative elastic impedance
Authors: Chen Huaizhen , Innanen Kristopher A. , Chen Tiansheng
Published: December 2017

P- and S-wave inverse quality factors quantify seismic wave attenuation, which is related to several key reservoir parameters (porosity, saturation, and viscosity). Estimating the inverse quality factors from observed seismic data provides additional and useful information during gas-bearing reservoir prediction. First, we have developed an approximate reflection coefficient and attenuative elastic impedance (QEI) in terms of the inverse quality factors, and then we established an approach to estimate elastic properties (P- and S-wave impedances, and density) and attenuation (P- and S-wave inverse quality factors) from seismic data at different incidence angles and frequencies. The approach is implemented as a two-step inversion: a model-based and damped least-squares inversion for QEI, and a Bayesian Markov chain Monte Carlo inversion for the inverse quality factors. Synthetic data tests confirm that P- and S-wave impedances and inverse quality factors are reasonably estimated in the case of moderate data error or noise. Applying the established approach to a real data set is suggestive of the robustness of the approach, and furthermore that physically meaningful inverse quality factors can be estimated from seismic data acquired over a gas-bearing reservoir.

At the 2017 SEG Annual Meeting in Houston, several students, including two students from Romania, asked me if there is a future for our industry. Listening to media stories of renewable energy replacing fossil fuel energy in a utopian decade or so, and electric cars replacing internal combustion cars, the students were wondering whether getting a degree in geology or geophysics is a good long-term career choice. After giving the students several variations on the same answer, I decided to write an entry on this subject for my personal blog and for TLE.

Introduction to this special section: Advancements in 3D seismic processing
Authors: Neidell Norman S. , Stark Tracy
Published: December 2017

Those geophysicists who are involved with and who use seismic data recognize the pivotal role of seismic data processing. The interpretive art also plays a ubiquitous role in many if not most facets related to seismic applications. To ideally discuss recent advances in seismic data processing, we would be well served if experts in broad areas prepared review papers offering insights on the state of the art as they see it and the role and significance of recent developments and directions. Such papers are rare. For that reason we wish to mention a work by Sam Gray that could not be included here because his submission to this special section had mostly been published previously as an expanded abstract for the 2014 SEG Annual Meeting ( Gray, 2014 ) and by the Geophysical Society of Houston in 2015.
Seismic interpretation when short-period internal multiples are present
Authors: Hilterman Fred , Nicholson Frank , Qi Chen
Published: December 2017

Seismic waves propagating in sedimentary sequences that include thin beds with large acoustic-impedance variations develop a distinct signature called stratigraphic filtering (SF). The source wavelet transforms into a low-frequency bell-shaped signal at the front end followed by a high-frequency noise coda. These effects produce low-frequency reflections that are delayed and exhibit poor continuity — a consequence of the short-period internal multiples. Applying a high-cut filter to the seismic and multiple synthetics removes noise coda and improves their correlation. Now, the need for multiple suppression of long-period internal multiples is evaluated. Multiple generators are easily identified for the multiple suppression process with synthetics morphing from primary only to primary plus multiples. Likewise, the stretch produced by SF is easily determined by inverting the primary and multiple synthetics for impedance correlation. The reduction in frequency is not desirable in the final product, so the high signal-to-noise low-frequency portion is extended to high frequency in the time-frequency domain. These principles are part of an interpretation workflow applied in Cooper Basin, Australia, which has as many as 50 coal beds of Permian age. By suppressing the SF effects from the Permian coal beds, the quality of fault and stratigraphic interpretation increases for units within the older Warburton Basin below the coal beds.
Extended resolution: Neidell is right
Authors: Robinson Enders A.
Published: December 2017

Norman Neidell was the first to show that higher frequencies can be obtained from observational digital data than those predicted by adherence to the Nyquist criteria. The result is extended resolution in computed seismic images. Holistic imaging is further confirmation that Neidell is right. An optical hologram acquires information about a 3D object on a 2D optical plate. When the hologram is illuminated, an optical image of the 3D object is formed. A seismogram (i.e., the acquired seismic data in a survey) acquires information about a 3D object on a 2D datum together with the additional dimension of time. When the seismogram is processed and imaged, a computer image of the 3D object is formed. From this analogy, it might be said that a seismogram is a hologram. A hologram depicts an image. An important feature of a hologram is that any portion of the hologram depicts the same image. It follows that in a seismic survey the number of shot points and detectors can be reduced without adversely affecting the results. The holistic imaging of the decimated seismogram depicts essentially the same image as the conventional imaging of the entire seismogram.
Subsalt imaging improvement possibilities through a combination of FWI and reflection FWI
Authors: Peng Chao , Wang Minshen , Chazalnoel Nicolas , Gomes Adriano
Published: December 2017

Despite continuous improvements in seismic acquisition and processing technology, imaging under salt remains challenging, specifically because of the difficulty in updating complex salt geometries and subsalt velocity. Synthetic studies show that when certain conditions are met, full-waveform inversion (FWI) can recover very complex velocity models, including the geometry of the salt and the subsalt velocity. Unfortunately, currently available seismic field data fall short of meeting the requirements needed to replicate what can be achieved on synthetic data. We first use a wide-azimuth data set from the Mexican side of the Gulf of Mexico (GOM) to show how FWI can improve imaging in the subsalt. In addition to utilizing the diving-wave energy to derive a reliable model in the shallow sediment overburden, we use reflection FWI (RFWI) to update the velocity model in the deep area. RFWI utilizes the low-wavenumber components of the FWI gradient associated with waves reflected in the model, which makes it possible to circumvent the well-known penetration-depth limitation of FWI and the shortcomings of traditional tomography-based methods. This is achieved by alternately using the high-wavenumber and low-wavenumber components of the FWI gradient to update density and velocity models, respectively. We then use an ultralong-offset, full-azimuth data set from the U.S. side of the GOM to show that, with more suitable data, FWI and RFWI can be combined to recover the velocity in and around complex salt bodies, providing significant uplift to subsalt images.

Not Everything That Shakes Is a Seizure: A Case Report
Authors: Jones Todd E. , Cibula Jean E. , Bohannon Don , Seubert Christoph N.
Published: December 2017

Not everything that shakes is an epileptic seizure. We present a patient who repeatedly exhibited severe shaking at emergence from general anesthesia. Her nonepileptic myoclonus was mistaken for a refractory seizure and treated with benzodiazepines and intravenous anesthetics. The resulting depressed level of consciousness rendered myoclonus clinically indistinguishable from refractory seizures. Over the course of 6 procedures, we found that levetiracetam, a first-line antiepileptic drug, effectively suppressed her myoclonus. The episodic nature of perioperative anesthesia care presents a challenge for differentiating myoclonus from seizure while balancing the concerns raised by different surgical procedures, rare comorbidities, and the subjective patient experience.

Identificam-se poucas pesquisas nacionais que cunham o termo ‘coaching’ como aspecto central de seus trabalhos; sendo assim, há baixo volume de publicação e pouca profundidade científica no tema, que tem, em contrapartida, apelo no mercado nacional. Para este artigo opta-se pela metodologia qualitativa, com método exploratório. Foram entrevistados em profundidade dois profissionais de coaching, prosseguindo a análise por meio da técnica de análise de conteúdo por grade fechada. Conclui-se que o abismo entre gerentes seniores e juniores é tecnológico e vivencial. As organizações estão interessadas em amenizar as diferenças da construção de carreira de ambos profissionais, a fim de absorver suas competências diferencialmente, para equilibrar o desenvolvimento e manutenção das lideranças gerenciais, garantindo a produtividade, a lucratividade e a diversidade.
ASPECTOS JURÍDICOS DA PUBLICIDADE INFANTIL

Published: December 2017

O Brasil não dispõe de um diploma legislativo específico sobre a publicidade infantil, o que gera uma série de repercussões negativas sobre o comportamento da criança e do adolescente, especialmente no que tange ao incremento da ânsia consumista desta parcela considerada hoje bastante considerável de consumidores. Os mecanismos utilizados por empresas de produtos ou serviços direcionados para este público específico, que estimulam e induzem o interesse na aquisição desses bens, deparam-se com um campo de ampla liberdade e imunidade quase que integral a limitações ou restrições, como consequência justamente da lacuna legislativa pertinente à matéria. Até existem instrumentos normativos que regem o assunto, a exemplo do Código de Defesa do Consumidor e do Estatuto da Criança e do Adolescente, porém tal regramento incide apenas indiretamente sobre a questão da publicidade infantil, cujo regramento limita-se àquele criado no âmbito da entidade privada de regulação da publicidade, o Conselho Nacional de Autorregulação Publicitária (CONAR) que, não obstante o esforço e a nobreza de suas intenções, não supre a contento a atividade regulatória e fiscalizadora da propaganda e da publicidade infantil. O presente ensaio, portanto, tem por objeto, justamente, as consequências jurídicas da inércia do legislador ordinário frente a assunto tão delicado e, ao mesmo tempo, de solução urgente.

Οι σύγχρονες κοινωνικο-οικονομικές συνθήκες που επικρατούν στην Ελλάδα (οικονομική κρίση, ανεργία, αύξηση των μονογονεϊκών οικογενειών) έχουν επηρεάσει σε μεγάλο βαθμό το ελληνικό εκπαιδευτικό σύστημα το οποίο είναι αντιμέτωπο με την έλλειψη των απαραίτητων οικονομικών πόρων, την υποβάθμιση των υλικοτεχνικών υποδομών, την απουσία προγραμμάτων επιμόρφωσης των εκπαιδευτικών και την περιορισμένη ανανέωση του εκπαιδευτικού προσωπικού. Λαμβάνοντας υπόψη τη σύγχρονη πραγματικότητα, η παρούσα έρευνα αποσκοπεί σε μια συστηματική καταγραφή των αναγκών που αντιμετωπίζουν οι νηπιαγωγοί οι οποίες υπηρετούν στα νηπιαγωγεία όλης της επικράτειας στην τρέχουσα συγκυρία. 600 νηπιαγωγοί από όλη την Ελλάδα συμπλήρωσαν ηλεκτρονικά ένα ερωτηματολόγιο με 50 ερωτήσεις σχετικές με βασικές δομές και λειτουργίες του σύγχρονου ελληνικού νηπιαγωγείου, όπως η καταλληλότητα του χώρου και η υλικοτεχνική υποδομή των νηπιαγωγείων, η λειτουργία του ολοήμερου νηπιαγωγείου, ο μετασχηματισμός του προγράμματος σπουδών, η συνεργασία με τους γονείς καθώς και για τις επιμορφωτικές ανάγκες τους. Ο σχεδιασμός και η υλοποίηση της έρευνας πραγματοποιήθηκε ύστερα από συνεργασία του Ινστιτούτου Εκπαιδευτικής Πολιτικής (ΙΕΠ) με το Τμήμα Νηπιαγωγών του Πανεπιστημίου Δυτικής Μακεδονίας (ΠΔΜ). Τα αποτελέσματα αναδεικνύουν σημαντικές ελλείψεις στο επίπεδο της υλικοτεχνικής υποδομής και στο χώρο μέσα και έξω από το νηπιαγωγείο.  Όμως, τα αποτελέσματα δείχνουν ότι οι νηπιαγωγοί μπορούν να υπερβούν τις δυσκολίες και να οργανώσουν ένα πλούσιο μαθησιακό περιβάλλον για τα παιδιά με διαφορετικές περιοχές παιχνιδιού και μάθησης. Επίσης, παρόλο που η πλειοψηφία των νηπιαγωγών αναγνωρίζει τη σημασία του ελεύθερου παιχνιδιού, οι μισές δηλώνουν ότι οι οργανωμένες δραστηριότητες κυριαρχούν στο ημερήσιο πρόγραμμα, υπογραμμίζοντας την έλλειψη ευελιξίας στο πρόγραμμα του νηπιαγωγείου. Σχετικά με τη συνεργασία νηπιαγωγείου-οικογένειας, οι νηπιαγωγοί δηλώνουν ότι καταφέρνουν να επικοινωνούν με τους γονείς συστηματικά και αποτελεσματικά. Όμως, φαίνεται να προτιμούν τη συμμετοχή των γονέων ως εθελοντών και ακροατών παρά ως συνδιαμορφωτών του εκπαιδευτικού  προγραμματισμού του νηπιαγωγείου. Η πλειοψηφία των νηπιαγωγών δίνει έμφαση στη συνεχιζόμενη επαγγελματική μάθηση που συνδέεται τόσο με τη διδακτική συγκεκριμένων γνωστικών αντικειμένων όσο και με ευρύτερα θέματα γενικής παιδαγωγικής γνώσης. Η έρευνα αποτελεί ένα πρώτο βήμα στην προσπάθεια συσχέτισης της εκπαιδευτικής πολιτικής με ερευνητικά αποτελέσματα, τα οποία μπορούν να οδηγήσουν στην ανάληψη πρωτοβουλιών που αφορούν στην καλύτερη λειτουργία των νηπιαγωγείων στη χώρα μας και στη βελτίωση του εκπαιδευτικού έργου που παρέχεται στην προσχολική εκπαίδευση.
Sociological Analysis of the Soviet Party Staff Politics

Industrialization in the Soviet Union is a genuine “economic miracle”. For a very mild historical period, in just one third of a century, the country’s economy, having begun with the destruction of the Civil War, having overcome the tests of the Patriotic War, has reached the level of a scientifi c and industrial complex capable of creating atomic bombs and space rockets. There are two opposite points of view explaining this “economic miracle.” The one — the economy of the Soviet Union was built by the prisoners of the GULAG; another point of view — the economy of our country was created by the hands of enthusiasts who believe in building a bright future. The article justifi es the third point of view: in our country, a staff mechanism was created, or a fram’s party apparatus, to select and promote personnel. Built into a social vertical elevator, it ensured the advancement of talented people upstairs, and the country’s economy with labor potential.

In a changing environment and inaccurate information, it is difficult to get an unambiguous answer about the quality of the candidate for the position, based only on the results of viewing the applicant’s questionnaires. As a consequence, recently there has been a trend towards the use of soft computing (neural networks, fuzzy logic and evolutionary computations) in tasks personnel’s selection. The article presents the solution of such a problem using the methods of soft computing for a software company. We use a neural-fuzzy system such as the ANFIS (Adaptive Network-Based Fuzzy Inference System) to quantify the candidate’s quality. The idea of neural-fuzzy systems is to determine the parameters of fuzzy systems through training methods used in neural networks. The most important advantage of this system lies in the automatic creation of the rules base. After completing the training, we receive an assessment of the quality of the candidate in the form of a scoring on a 10-point scale. In addition, we derive a regression equation that relates the candidate’s quality with the input variables.

This paper is a sequel to earlier papers on time parameters of solar flares in the Hα line. Using data from the International Flare Patrol, an electronic database of solar flares for the period 1972–2010 has been created. The statistical analysis of the duration of the main phase has shown that it increases with increas-ing flare class and brightness. It has been found that the duration of the main phase depends on the type and features of development of solar flares. Flares with one brilliant point have the shortest main phase; flares with several intensity maxima and two-ribbon flares, the longest one. We have identified more than 3000 cases with an ultra-long duration of the main phase (more than 60 minutes). For 90 % of such flares the duration of the main phase is 2–3 hrs, but sometimes it reaches 12 hrs.
Sky-distribution of intensity of synchrotron radio emission of relativistic electrons trapped in Earth’s magnetic field
Authors: Клименко Владимир , Klimenko Vladimir
Published: December 2017

This paper presents the calculations of synchrotron radio emission intensity from Van Allen belts with Gaussian space distribution of electron density across L-shells of a dipole magnetic field, and with Maxwell’s relativistic electron energy distribution. The results of these calculations come to a good agreement with measurements of the synchrotron emission intensity of the artificial radiation belt’s electrons during the Starfish nuclear test. We have obtained two-dimensional distributions of radio brightness in azimuth — zenith angle coordinates for an observer on Earth’s surface. The westside and eastside intensity maxima exceed several times the maximum level of emission in the meridian plane. We have also constructed two-dimensional distributions of the radio emission intensity in decibels related to the background galactic radio noise level. Isotropic fluxes of relativistic electrons (E ~ 1 MeV) should be more than 107 cm–2s–1 for the synchrotron emission intensity in the meridian plane to exceed the cosmic noise level by 0.1 dB (riometer sensitivity threshold).

In Earth’s orbit on June 28, 1999, there was a diamagnetic structure (DS) representing a filament with a uniquely high speed (about 900 km/s). We show that the filament is a part of the specific sporadic solar wind (SW) stream, which is characterized as a small interplanetary transient. We report the results of studies on the interaction between such a fast filament (DS) and Earth’s magnetosphere. Around noon hours at daytime cusp latitudes, we recorded a powerful aurora in the UV band (shock aurora), which rapidly spread to the west and east. Ground-based observations of geo-magnetic field variations, auroral absorption, and auro-ras on the midnight meridian have shown the develop-ment of a powerful substorm-like disturbance (SLD) (AE~1000 nT), whose origin is associated with the im-pact of the SW diamagnetic structure on the magneto-sphere. The geostationary satellite GOES-8, which was in the midnight sector of the outer quasi-capture region during SLD, recorded variations of the Bz and Bx geo-magnetic components corresponding to the dipolization process.

The phenomena which accompany synchronization of night-time ionospheric and geomagnetic disturbances in an ULF range with periods 35–50 min near the mid-latitude station Kazan during a global magnetically quiet period have been analyzed. The comparison between dynamic spectra and wavelet patterns of these disturbances has revealed that spectral features of simultaneous disturbances of the F2-layer critical frequency and H, D, Z geomagnetic field components are similar. By studying spectral features of the F2-layer critical frequency over Kazan and disturbances of the H and D geomagnetic field components at magnetic stations which differ from Kazan station in longitude and latitude, we have established that the disturbances considered belong to the class of fast magnetosonic waves. The analysis of solar wind parameters, inter-planetary magnetic field (IMF), and values of the auro-ral index AL in the period under study has shown that this event is associated with IMF Bz component disturb-ances and occurs during substorm development.

As part of the Plasma–Progress and Radar–Progress space experiments conducted from 2006 to 2014, effects of the Progress spacecraft engines on the ionosphere have been studied using data from Global Navigation Satellite System (GNSS) receivers. 72 exper-iments have been carried out. All these experiments were based on data from the International GNSS Service (IGS) to record ionospheric plasma irregularities caused by engine operation. 35 experiments used data from the ISTP SB RAS network SibNet. The analysis of the spatio-temporal structure of total electron content (TEC) variations has shown that the problem of identifying the TEC response to engine operation is complicated by a number of factors: 1) the engine effect on ionospheric plasma is strongly localized in space and has a relatively low intensity; 2) a small number of satellite—receiver radio rays due to the limited number of GNSS stations, particularly before 2013; 3) a potential TEC response is masked with background ionospheric disturbances of various intensi-ties. However, TEC responses are identified with certainty when a satellite—receiver radio ray crosses a disturbed region within minutes after the impact. TEC responses have been registered in 7 experiments (10 % of cases). The amplitude of ionospheric response (0.3–0.16 TECU) exceeded the background TEC variations (~0.25 TECU) several times. The TEC data indicate that the ionospheric irregularity lifetime is from 4 to 10 minutes. According to the estimates we made, the transverse size of irregularities is from 12 to 30 km.
