How Can Collaboration between Schools and Workplaces Contribute to Relevant Vocational Education?
Authors: Hiim Hilde 
Published: October 2022

AbstractCollaboration between schools and enterprises in vocational education and training (VET) is a challenge in many countries, Norway included. There is a tendency to organise VET in separate theoretical and practical learning arenas that lack mutual coherence. This article presents the findings of a four-year action research study in which 30 vocational teachers, who were taking an in-service master’s degree programme in vocational pedagogy, completed systematic research-based projects on developing partnerships between schools and enterprises in the school-based part of Norwegian VET. The goal was to strengthen the relevance of vocational education by creating stronger links between the content of the education and the content of the vocation. The study was based on a pragmatic, holistic perspective on vocational competence and education where essential, authentic vocational tasks to which theory is related are regarded as the core educational content, both in the enterprises and in schools. The findings are based on an analysis of 30 master’s degree theses documenting each of the teachers’ development projects.The results show examples of and principles for how collaboration between schools and enterprises can be organised around vocational tasks. Core principles include formal agreements on collaboration between schools and enterprises, regular dialogues between vocational teachers, instructors and students about educational tasks and content, joint planning and follow-up of students’ placements in enterprises, and exchanges of experience and competence between teachers and instructors. The results show that, according to students, instructors and vocational teachers, the application of such principles contributed to vocational relevance and students’ motivation and learning outcomes.

Abstract
Purpose
The aim of the present study is to evaluate the results of our all posterior-one stage surgical technique for the reduction and fusion of high-grade high-dysplastic spondylolisthesis.

Methods
Patients over 11 years old with high-grade spondylolisthesis treated by reduction and circumferential fusion with a posterior-only approach were reviewed. Data about operative time, blood loss, length of stay, intra- and postoperative complications were collected. Meyerding grade (M), lumbar lordosis (LL), thoracic kyphosis (TK), pelvic incidence (PI), pelvic tilt (PT), lumbosacral angle (LSA), slip angle (SLIP), lumbar index (LI) and severity index were measured on preoperative and last follow-up. Sagittal vertical axis (SVA) was used to assess sagittal balance.

Results
Of the 14 included patients, L5-S1 arthrodesis was performed in 12 cases, and L4-S1 was performed in 2 cases. Average surgical time was 275 ± 65 min; average blood loss was 635 ± 375 mL. Average length of stay of was 3.9 ± 1.5 days. The SLIP angle improves from 33.8° ± 7.3° to 6.4° ± 2.5°, (p = 0.002); the lumbosacral angle improves from 68.8° ± 18.6° to 100.7° ± 13.2°, (p = 0.01); and the SVA decreased from 49.4 ± 22.1 mm to 34.4 ± 8.6 mm (p = 0.02). No significant changes were observed in PI, PT and SS. Thoracic kyphosis (TK) and lumbar lordosis (LL) did not change significantly. At last follow-up, no patient had surgical site infection or mechanical complications; no pseudoarthrosis was observed. No revision surgery was performed.

Conclusion
Although technically demanding, reduction and fusion with one stage all posterior approach prove to be a safe and effective.
The provenance and history of Abu Muharak barchan sands (Kharga Depression) inferred from textural, mineralogical, and geochemical perspectives

Published: October 2022

Abstract
The current study deals with textural, mineralogical, and geochemical characteristics of the barchan dune sands of Abu Muharak dune belts in the Kharga Depression. Abu Muharak is the longest dune belt in the Western Desert of Egypt. Sand samples from 37 sites were texturally, petrologically, and chemically analyzed. Our goals were to interpret the provenance of the sands in terms of grain size, petrology, and geochemistry and correlate these data with the proposed source such as Nubian sandstone, Pleistocene alluvial, and Holocene lacustrine sediments as well as ancient aeolian deposits exposed at the Kharga Depression. The present study concludes that the Moghra sandstone is the main source of the Abu Muharak dune belt with local contributions from Pleistocene alluvial and dune deposits as well as weathered Nubian sandstone in the Kharga Depression.
The use and application of learning theory in learning analytics: a scoping review
Authors: Khalil Mohammad , Prinsloo Paul , Slade Sharon 
Published: October 2022

AbstractSince its inception in 2011, Learning Analytics has matured and expanded in terms of reach (e.g., primary and K-12 education) and in having access to a greater variety, volume and velocity of data (e.g. collecting and analyzing multimodal data). Its roots in multiple disciplines yield a range and richness of theoretical influences resulting in an inherent theoretical pluralism. Such multi-and interdisciplinary origins and influences raise questions around which learning theories inform learning analytics research, and the implications for the field should a particular theory dominate. In establishing the theoretical influences in learning analytics, this scoping review focused on the Learning Analytics and Knowledge Conference (LAK) Proceedings (2011–2020) and the Journal of Learning Analytics (JLA) (2014–2020) as data sources. While learning analytics research is published across a range of scholarly journals, at the time of this study, a significant part of research into learning analytics had been published under the auspices of the Society of Learning Analytics (SoLAR), in the proceedings of the annual LAK conference and the field’s official journal, and as such, provides particular insight into its theoretical underpinnings. The analysis found evidence of a range of theoretical influences. While some learning theories have waned since 2011, others, such as Self-Regulated Learning (SRL), are in the ascendency. We discuss the implications of the use of learning theory in learning analytics research and conclude that this theoretical pluralism is something to be treasured and protected.
Study on laser transmission interference characteristics based on atmospheric turbulent medium
Authors: Yang Xiaodong , Dong Qunfeng 
Published: October 2022

AbstractThe characteristics of laser transmission interference in the atmospheric turbulent medium are studied in this paper in order to obtain the target interference image with atmosphere as the transmission medium and obtain more accurate detection targets. First, the influence of the laser cross section radius and transmission distance on the laser intensity is analyzed, and thereby, the intensity model of lights transmitted in the turbulent medium is obtained. Through the combination of such model with the ideal reference light, the characteristics of atmospheric turbulent medium-based laser transmission interference are obtained. The influencing factors and the significance degree of influence of interference contrast are analyzed in detail. Studies have shown that the attenuation of laser intensity in the atmospheric turbulent medium is obvious and can be effectively adjusted by increasing the cross section radius. The laser interference contrast is also affected by the cross section radius and transmission distance; of the two, the latter has more obvious influence.

AbstractThe Nirano Salse, known since the Roman Times, are one of the most beautiful and scenic mud volcanoes areas of Italy with thousands of visitors every year. In this work, we apply novel (for the context) hydrogeological techniques to characterize mud levels in the Salse by means of GPS-RTK positioning and continuous level logging within mud conduits. This is important to quantify the gas–liquid ratio in the conduits and evaluate the potential for dangerous abrupt mud eruptions. The results presented suggest that different mud levels in mud volcanoes clusters are due to the different gas–liquid ratio in the conduits and not necessarily exclude interconnection at depth, a hypothesis, on the other hand, that seems strengthened by mud level time series correlations. The presence of shallow aquifers at a depth of 5 to 30 m is also supported by our field data and allows us to delineate the boundaries of the shallow mud reservoir—pipes system and its overall shape. The shallow aquifers may provide a temporary storage for the ascending gas and when fluid pressure in these aquifers exceeds the tensional strength of the sedimentary rock, leakage of fluids to the surface would occur. In this case, if the gas–liquid ratio is high, mud volcanoes develop into tall gryphons and tend to have a discontinuous activity with sudden eruptions of mud after long periods of quiescence. This, together with the knowledge of shallow conduits localization has an important implication for site safety in proximity to the mud volcanoes. Our inferences based on mud level relationships to mud extrusion dynamics can be applied to lower risk in other mud volcanoes areas of the world with high geo-tourist visits, such as those of Trinidad, Azerbaijan, and Colombia.

Published: October 2022

AbstractRecognition of the multiple types of value of marine resources is crucial to help design locally meaningful and sustainable management approaches for marine and coastal habitats. There is a lack of information on the amount of living marine resources harvested by coastal communities in many Pacific Island Countries and Territories (PICTs), as well as on their economic and non-economic value. This paper explores the monetary, subsistence, and sociocultural value of selected marine resources (finfish and invertebrates) in Kadavu province, Fiji, based on a household survey and semi-structured interviews conducted in 2019 within one specific district. The paper provides estimates of the annual catch and monetary value of marine resources harvested by local communities at both the district and provincial levels, derived from catch and effort information collected from fishers and gleaners in situ. It also highlights the importance of integrating the sociocultural significance of marine resources into future value assessments.
Mawng maths: collaborating to teach mathematics in an Australian Indigenous language
Authors: Edmonds-Wathen Cris , Gumurdal Jacobina 
Published: October 2022

AbstractThere are both educational and cultural benefits to first language (L1) instruction, particularly in the early years of school, but in Australia, few Indigenous language–speaking students are taught in their own languages. Teaching mathematics in Indigenous languages requires both linguistically capable Indigenous educators and the identification and development of suitable mathematics terminology. This paper reports on the collaborative development of a program reintroducing mathematics lessons in Mawng language at Warruwi Community School. This project developed the capacity of an Indigenous educator to take on more responsibility for the content of the class teaching. Lessons focussing on spatifal sequencing terminology were developed to extend students’ use of core Mawng grammatical features while also reinforcing important local cultural knowledge. A collaboration between a non-Indigenous researcher and a Mawng educator, the paper concludes with factors contributing to the sustainability of the project.

Published: October 2022

Abstract

Objectives
Autism spectrum disorder (ASD) symptoms can become more evident because of different factors. Among these, depression, anxiety, and stress play an important role. Additionally, several studies have revealed the impact of the COVID-19 pandemic on participants with ASD. In previous studies, two noninvasive neurobiological stimulation treatments with radio electric asymmetric conveyer (REAC) technology, called neuropostural optimization (NPO) and neuropsychophysical optimization (NPPO), were shown to be effective in improving the subjective response to environmental stressors in the general population and in ASD population. Based on the proven efficacy of REAC NPO and NPPOs treatments in alleviating anxiety, stress, and depression, the purpose of this study is to verify how these treatments can reduce the severity of ASD symptoms expression, which is aggravated by depression, anxiety, and stress. The treatments’ effects were perceived by caregivers and assessed by the Autism Treatment Evaluation Checklist (ATEC).

Methods
This study involved 46 children with a previous diagnosis of ASD made using the Autism Diagnostic Observation Schedule and Autism Diagnostic Interview-Revised. The participants received one session of NPO treatment and one NPPOs treatment cycle of 18 sessions, administered within approximately 3 weeks. The Autism Treatment Evaluation Checklist (ATEC) was used to evaluate the efficacy of the REAC treatments. ATEC allows to evaluate four clusters (speech or language communication; sociability; sensory or cognitive awareness; and health/physical/behavior) through a numerical scale that measures increasing levels of ASD severity.

Results
The comparison between the scores of the ATEC administered pre- and post-REAC treatments highlighted an improvement of ASD symptoms in each of the four clusters of ATEC.

Conclusions
The results confirm the usefulness of REAC treatments to optimize the individual response to environmental stressors and reduce the symptomatic expression and deficits present in ASD.

Published: October 2022

Abstract
In this study, we investigate how miscibility develops in naturally fractured reservoirs. We select and simulate compositionally a sector model of a real and highly naturally fractured reservoir of type 2, and the behavior of the reservoir under the influence of different gases injection, including methane, carbon dioxide, lean and rich gas investigated. The minimum miscibility pressure of each gas and the optimum gas injection rate is determined. The effect of injected gas type on solution gas–oil ratio, surface tension, and viscosity of reservoir fluid studied. Results of this study show that the oil recovery factor in the simulation sector model over 25 years of simulation for the natural depletion scenario is 15.2% while for the miscible gas injection at the optimum injection rate is 16.7, 18.8, 17.46, and 19.4% for methane, carbon dioxide, lean gas, and rich gas respectively. Also, an improvement in the development of miscibility in the case of rich gas injection at this type of natural fractured reservoirs observed.

Article Highlights

To reach the highest RF, Gas Injection rate optimization is necessary at this type of NFRs.

Injection of methane and lean gas at higher rates causes faster gas breakthrough and leads to lower ultimately oil.

The rich gas shows better miscibility condition than other gases at this type of NFRs.
Seismic refraction data inversion via jellyfish search algorithm for bedrock characterization in dam sites
Authors: Poormirzaee Rashed 
Published: October 2022

AbstractSeismic refraction method is an efficient tool for the investigation of dam construction sites. Velocity inversion has an essential role in an accurate seismic refraction data interpretation. This study aims to develop a new inversion algorithm to estimate P-wave velocity (Vp) structure from seismic refraction travel times. The introduced inversion algorithm is based on a recently developed nature-inspired algorithm, i.e., jellyfish search (JS) optimizer. First, the JS-based inversion algorithm was tested by several synthetic models in the presence of noise and without noise. Then, the performance of the applied inversion algorithm was evaluated by the seismic refraction travel times at a realistic dam construction site. The main objective of the actual data set analysis is the determination of Vp structure to find overburden thickness. The JS-based inversion algorithm in both synthetic models and actual data set shows acceptable performance. Results show three distinct seismic layers at the dam site. The velocities of the first, second and third layers, respectively, were estimated 400 m/s, 600 m/s and 1400 m/s. Also, the overburden thickness was estimated about 23 m, which was consistent with borehole data. The performance of the applied algorithm in the analyzing of actual data set was compared with the tomography interpretation method that the results revealed the efficiency of the JS-based inversion method.

Published: October 2022

AbstractTechnological advancement of the last decades allowed one to develop the process of documentation and popularize the cultural heritage in the form of spatial objects and structures by means of reality modelling. The main goal of the article was to develop a methodology based on the compilation of activities in the field of acquisition (UAV), processing (Metashape and SkechUp), and publication (YouTube) of the data for the purpose of documentation and promotion of topographic cultural heritage objects recorded on nineteenth century maps (pre-industrial landscape). The research was carried out on a windmill located in Kamionka (Poland). It is located in the region of Wielkopolska (Witkowo borough), the cultural landscape of which, despite the progressive industrialization in the nineteenth century, has been shaped mainly by the agricultural land use. The most important results obtained at subsequent stages of the work were finally presented in the form of a short film. This type of presentation based on the use of multimedia is a comprehensive form of sharing research results. YouTube, as the leading medium for publishing audiovisual content, is one of the best places to share research results related to the promotion of cultural heritage.
Urban informatics and spatial optimization
Authors: Murray Alan T. , Baik Jiwon 
Published: October 2022

AbstractThere has been much concern for sustainability issues, recognizing the significant impacts that humans have had and continue to have on the Earth. Urban informatics has much to offer city systems in terms of understanding, management and design, particularly associated with sustainability. Efficiency that characterizes sustainable systems, and strategic goals to achieve them, does not happen by chance, but rather is the byproduct of concerted efforts driven by informed decision making. This paper focuses on strategic decision making, and the role of spatial optimization as a component of urban informatics. Strategic siting involving access and coverage demonstrates the capabilities of spatial optimization, but more importantly highlights the significance of an urban informatics perspective.
Estimating the Geological Structure and Transport Properties of Denied and Limited Access Sites
Authors: Duncan N. A. , Deinert M. R. 
Published: October 2022

AbstractOnsite measurements are the standard for establishing geological conditions and related transport properties. However, making direct measurements is not always possible, either because a location is too remote, too vast, or access is outright denied. The latter is typically the case at nuclear test sites, or military installations. Here we describe a systematic method to characterize geology and estimate fracture width, spacing, tortuosity, permeability, and porosity at locations where direct measurements cannot be made. Fractures are treated as fractals with their respective fractal dimensions determined using surface images. Tortuosity in the geological matrix (i.e., bulk media) is determined using rock class with the latter also being used to determine distributions for permeability and porosity. The approach is tested using areal images and rock class for the Nevada Test Site and validated by comparison to field and core measurements. Past work has shown that testing a nuclear weapon underground can affect not only the migration time for gases to the surface but also their isotopic ratios. Accurately modeling gas transport and isotopic fractionation requires knowledge of the geology. However, suspected tests are typically conducted at sites to which the international community has no access.

AbstractDropout events are dramatic decreases in radiation belt electron populations that can occur in as little as 30 minutes. Loss to magnetopause due to a combination of magnetopause shadowing and outward radial transport plays a significant role in these events. We examine the dropout of relativistic electron populations during the October 2012 geomagnetic storm using simulated electron phase space density, evaluating the contribution of different processes to losses across the magnetopause. We compare loss contribution from outward transport calculated using a standard empirical radial diffusion model that assumes a dipolar geomagnetic field to an event‐specific radial diffusion model evaluated with a non‐dipolar geomagnetic field. We additionally evaluate the contribution of Shabansky type 1 particles, which bounce along magnetic field lines with local equatorial maxima, to the loss calculated during this event. We find that the empirical radial diffusion model with a dipolar background field underestimates the contribution of radial diffusion to this dropout event by up to 10% when compared to the event‐specific, non‐dipolar radial diffusion model. We additionally find that including Shabansky type 1 particles in the initial electron phase space density, that is, allowing some magnetic field lines distorted from the typical single‐minima configuration in drift shell construction, increases the calculated loss by an average of 0.75%. This shows that the treatment of the geomagnetic field significantly impacts the calculation of electron losses to the magnetopause during dropout events, with the non‐dipolar treatment of radial diffusion being essential to accurately quantify the loss of outer radiation belt populations.
