Understanding the role of single‐board computers in engineering and computer science education: A systematic literature review

In the last decade, single‐board computers (SBCs) have been employed more frequently in engineering and computer science (CS) at both technical and educational levels. These devices are of importance to educators and students due to several factors such as the versatility, the low cost, and the possibility to enhance the learning process through technology. However, the implications, possibilities, and constraints of these devices in engineering and CS education have not been explored in detail. In this systematic literature review, we explore how the SBCs are employed in engineering and CS and what educational results are derived from their usage in the period 2010–2020 at tertiary education level. For this, 154 studies were selected out of n = 605 collected from the academic databases Ei Compendex, Inspec, and ERIC. The analysis was carried out in two phases, identifying, for example, areas of application, learning outcomes, and students' and researchers' perceptions. The results of the review mainly indicate the following aspects: (1) The areas of laboratories and e‐learning, computing education, robotics, Internet of Things, and persons with disabilities gather the studies in the review. (2) Researchers highlight the importance of the SBCs to transform the curricula in engineering and CS for the students to learn complex topics through experimentation in hands‐on activities. (3) The typical cognitive learning outcomes reported by the authors are the improvement of the students' grades and the technical skills regarding the topics in the courses. Concerning the affective learning outcomes, the increase of interest, motivation, and engagement is commonly reported by the authors.
Political Polarisation in Greece: The Prespa Agreement, Left/Right Antagonism and the Nationalism/Populism Nexus

ABSTRACT Following the signing of the Prespa Agreement in June 2018, the Macedonian name issue became the most prominent topic on the Greek political agenda, catalysing an exceptional political confrontation and contributing to the realignment of political parties and eventually to government change. Analysing the political discourse and public debate on the issue from January 2018 until the July 2019 national elections, as well as opinion polls and electoral results, the paper explores the conditions leading to the escalation of political polarisation on the left/right axis, at the expense of smaller centrist parties. It is argued that political antagonism was built on the previous political cleavage (although the populist/anti-populism axis was now reversed). By mobilising public emotions around an alleged ‘national threat’, the polarisation around the Macedonian name issue proved far more successful for the Greek right than for the left.
Soil texture and other site-level factors differentially affect growth of Scotch broom (Cytisus scoparius) and Douglas-fir (Pseudotsuga menziesii) seedlings in the western Pacific Northwest

The invasive shrub Scotch broom (Cytisus scoparius (L.) Link) is a pervasive threat to regenerating Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) stands in the Pacific Northwest, USA. Field observations indicate that the susceptibility of areas to Scotch broom invasion and dominance can vary by site. We selected ten sites throughout the western Pacific Northwest that spanned a gradient of soil textures and other factors to test the site-specific susceptibility of Douglas-fir to overtopping by Scotch broom. We expected to find that the ability of Scotch broom to dominate a site was mediated by site-level factors, particularly those influencing soil water – the most limiting factor to growth in the region. We found Scotch broom and Douglas-fir were inversely affected by site-level factors. In general, Douglas-fir absolute height growth rates were more competitive with those of Scotch broom on fine-textured soils than on more coarsely textured soils. We also found Douglas-fir to have a more dramatic response to increasing down woody material than Scotch broom. Scotch broom height growth approached an asymptote at 3 m. Sites with fast-growing Douglas-fir were able to surpass this height six to seven years after planting and appear likely to avoid suppression by Scotch broom.
Identifying the Central Components of Perceived Costs and Benefits of Helping Peers with Depression: A Psychological Network Analysis Using Japanese Undergraduate Samples

: Several training programs and forums for mental health peer support have been developed, and perceptions of costs and bene ﬁ ts affecting peer supporters ’ helping behaviors have been investigated. To investigate the most ef ﬁ cient ways to motivate people to provide mental health peer support, we conducted a series of cross-sectional network analyses that (a) visualized the network structures of the perceived costs and bene ﬁ ts of helping or not helping peers with depression; and (b) identi ﬁ ed the most central component in each network. Participants were 297 Japanese undergraduates (mean age = 19.27 years) who rated how much they cared about items related to the costs/bene ﬁ ts of helping/not helping using a Likert scale. A series of psychological networks consisting of nodes (com-ponents) connected by edges (regularized partial correlations) were estimated, and the most central component judged on the basis of high scores for strength, closeness, and betweenness indexes was identi ﬁ ed in each network (e.g., “ loss of energy ” in the Costs of Helping network). Discussion focuses on these identi ﬁ ed central components as targets for intervention within the larger networks of perceived costs and bene ﬁ ts.
Chronic Lead Exposure Alters Mineral Properties in Alveolar Bone

The objective of the present study was to investigate the effects of chronic lead exposure on the mineral properties of alveolar bone. For this purpose, female Wistar rats (n = 8) were exposed to 1000 ppm lead acetate in drinking water for 90 days, while the control group (n = 5) was treated with sodium acetate. The alveolar bone structure and chemical composition of the dissected mandibles were examined using micro-computed tomography (micro-CT), scanning electron microscopy (SEM), inductively coupled plasma optical emission spectrometry (ICP-OES), attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), and X-ray diffraction (XRD) techniques to determine possible alterations in alveolar bone due to lead exposure. In addition, changes in bone mechanical properties were analysed using a three-point bending test. Exposure to lead induced notable changes in bone mineralization and properties, specifically a reduction of the trabecular thickness and bone mineral density. Furthermore, there was a reduction in carbonate content and an increase in bone mineral crystallinity. These changes in bone mineralization could be explained by an alteration in bone turnover due to lead exposure. Three-point bending showed a trend of decreased displacement at failure in the mandibles of lead-exposed rats, which could compromise the mechanical stability and normal development of the dentition.
Two Decades (2000–2020) Measuring Urban Sprawl Using GIS, RS and Landscape Metrics: a Case Study of Municipality of Prishtina (Kosovo)

Since the appearance on Earth, human has been constantly operating in nature, exploiting its riches, but also adapting it to its own needs. Both developing and developed countries are constantly concerned about the urbanization process. Urbanization, in order to be positive, must be developed correctly. If such a thing does not happen, then this development will negatively affect both the environment and human health. In order to develop adequate strategies and policies for the most sustainable and effective land use management, it is necessary to quantify, monitor, determine the factors that have influenced this change in land use and the spread mapping of the urban environment. In this study, Landsat satellite images were used to determine the spatial-temporal characteristics of the urban sprawl environment in the Municipality of Prishtina for a period of 20 years (2000–2020). To map the land cover for Prishtina from 2000 to 2020, the Supervised maximum likelihood classification was used using the Landsat ETM + and OLI data archives in ArcGIS 10.5 software. Using landscape metrics and detection techniques after the classification of satellite images, enabled and assisted in the evaluation and analysis of trends and patterns of urban sprawl. The determination of the changes and the analysis made revealed that during the period 2000–2020, in Prishtina, there was an increase of the built areas by 16.46 km2 at the expense of the unbuilt areas. That there has been an increase in urban areas was also confirmed by the results of landscape metrics.
Experimental Study of a System for Hydrogen Permeation from Gas Phase to Liquid Sodium

Abstract In the framework of sodium fast reactors, the management of tritium contamination in the sodium secondary circuit and the control of its release into the atmosphere is fundamental. In order to capture and recover tritium by coprecipitation worth hydrogen in cold traps, it is necessary to maintain a certain amount of hydrogen dissolved in the liquid sodium stream. Hydrogen injection by permeation through nickel membranes has been proposed to provide a continuous hydrogen intake to a liquid sodium stream, allowing the desired hydrogen concentration to be reached. A permeator prototype and the related process have been designed. Permeation tests have been carried out in an experimental facility set up at CEA Cadarache at sodium temperatures from 375°C to 450°C and hydrogen partial pressures from 5 × 103 to 3 × 104 Pa in order to quantify their influence on hydrogen permeation flux. Measurements on both the gas and sodium sides provide a complete hydrogen content observability over the system. Experimental results show a good agreement with the theoretical permeation laws for hydrogen pressures below 2 × 104 Pa and provide an estimation of the temperature dependency of the permeability coefficient, which will be useful for the industrial scale-up of the process.
The Nomological Network of the Short Dark Tetrad Scale (SD4)

The present study examined the nomological network of the Short Dark Tetrad scale (SD4). The SD4 measures narcissism, psychopathy, Machiavellianism, and sadism. We translated the original English SD4 into German and used an online sample (N = 594, 77% women) to investigate its nomological network with regard to the Big Five, honesty-humility, maladaptive personality traits, impulsivity, aggression, motives, values, sociosexual orientation, the octants of the interpersonal circumplex model, and self-esteem. The overall profile similarities between the observed and hypothesized nomological networks were very high. Few correlations differed concerning direction or magnitude. Hence, our study extends the nomological network of the Dark Tetrad in a meaningful way and suggests that the SD4 can be validly interpreted and used for the assessment of narcissism, psychopathy, Machiavellianism, and sadism.
An Empirical Evaluation of Budget Implementation on Economic Development in Nigeria

One of the primary goals of this study was to explore how a budget review approach may affect Nigeria's economic development. The reasoning was that the Nigerian economy was being challenged by a variety of imbalances in budget creation and implementation. The study strategy was based on events that occurred after the study was completed, and the data used in the study came from the Central Bank Statistical Bulletin and the Federal Ministry of Finance. A model was constructed based on both empirical and theoretical investigations in order to achieve this broad goal. The HDI, which was utilized as a measure of development, was the dependent variable in the model. The government's capital budget, recurrent budget, and the speed of annual budget implementation were the other independent variables in the model. They examined data using the Auto Regressive Distributed Lag (ARDL) Model, diagnostic tests such as the test of normality, auto correlation test, and heteroskedasticity test, which proved the validity and reliability of the model they chose; inferential results reveal that the use of budget evaluation had a positive and significant impact on the Nigerian economy. According to the study's suggestions, Nigeria's government should try to increase capital and recurrent expenditures in its annual budget, both of which have a significant impact on economic development. Finally, the government should work to build budget monitoring and review infrastructure that will aid in the effective implementation of large budget expenditures while also ensuring compliance with legal procedures.
Adoption of ICTs in Agri-Food Logistics: Potential and Limitations for Supply Chain Sustainability

A major challenge of Sustainable Development Goal 12 “Responsible Consumption and Production” is to reduce food losses along production and supply chains. This is particularly critical for fresh food products, due to their perishable and fragile nature, which makes the coordination of the actors all the more crucial to avoid wastes and losses. The rise of new technologies, referred to as “Industry 4.0” powered by the internet of things, big data analytics and artificial intelligence, could bring new solutions to meet these needs. Information and communication technologies (ICTs) allow for frequent exchanges of huge amounts of information between actors in the agrofood chains to coordinate their activities. The aim of the chapter is to provide a state-of-the-art analysis on ICTs used in agrofood supply chains, with a special focus on the case of fresh fruits and vegetables, to analyze the potential and weaknesses which exist in different forms of supply chains for ICTs becoming a “resource” (precious, rare, non-imitable, and nonsubstitutable) prospect and to suggest promising ICTs in this context.
Grapevine Anatomy as a Possible Determinant of Isohydric or Anisohydric Behavior

Isohydric plants maintain constant water potential through rapid stomatal closure, whereas anisohydric plants only close their stomata at very low water potentials. However, distinctions between isohydric and anisohydric behaviors among different cultivars of the same species are unclear. This study compared the physiological response to prolonged drought stress in the isohydric Grenache and the anisohydric Shiraz cultivars of the Vitis vinifera species. Plants were exposed to 60-day periods of deficit irrigation (25% of plant water consumption under well-watered conditions) during the summers of 2011 and 2012. Physiological measurements, water potential, leaf gas exchange, canopy area, leaf senescence, stem characteristics, and morphological characteristics were analyzed. Stomatal conductance was consistently lower in Grenache than in Shiraz at all values of midday stem and predawn leaf water potentials, respectively. The Shiraz plants exhibited greater vegetative growth and less defoliation than the Grenache plants in response to water deficit. Anatomical architecture analyses revealed that Grenache plants had greater xylem vessel diameter, hydraulic conductivity, and stomatal density than the Shiraz plants. These results suggest isohydric and anisohydric behaviors may be well-defined, time-regulated responses rather than distinct mechanisms that plants use to cope with drought stress. The rapid response to water deficit exhibited by isohydric plants may be because they are more vulnerable to fatal xylem embolisms than anisohydric plants. Thus, the accelerated response allows isohydric plants to avoid drought stress and minimize risk of xylem cavitation, but may lower the plant’s ability to survive moderate stress of prolonged drought.
Dissolution of Carbonate Rocks in a Laboratory Setting: Rates and Textures

Determining the dissolution rates of carbonate rocks is vital to advancing our understanding of cave, karst, and landscape processes. Furthermore, the role of carbonate dissolution is important for the global carbon budget and climate change. A laboratory experiment was setup to calculate the dissolution rates of two whole rock carbonate samples with different petrographic makeup (ooids and brachiopods). The carbonate rock samples were also explored under a scanning electron microscope to evaluate the textures that developed after dissolution The oolitic limestone dissolved at a rate of 1579 cm yr−1, and the pentamerous limestone (dolostone) dissolved at a rate of 799 cm yr−1. Both rocks did not dissolve evenly across their surface as indicated by scanning electron microscopy, it appears the allochems dissolved preferentially to the matrix/cement of the rocks and that some mechanical weathering happened as well. This work reports that the petrography and mineralogy of carbonate rocks is important to consider when exploring the cave, karst, and landscape evolution and that attention should be paid to the petrography of carbonate rocks when considering the global carbon budget.
Design and Analysis Comparison of Surface Acoustic Wave-Based Sensors for Fabrication Using Additive Manufacturing

Sensors have become an integral part of our everyday lives by helping us converting packets of data to make important decisions. Due to this reason, researches are done constantly to improve the fabrication processes of sensors by making them more user-friendly, less time-consuming, and more cost-effective. The application of any fabrication solution that offers those advantages will have a major impact on the manufacturing of modern sensors. To address this issue, a 3D printed Surface Acoustic Wave (SAW) temperature sensor is presented in this paper. The modelling and analysis of such a sensor have been performed for both aluminium and copper electrodes using COMSOL software. In total, 4 different sensing structures, 2 each for both aluminium and copper electrodes based one-port resonators, are designed and analysed for their application in temperature sensing. The resulting responses of those sensors are approximately 2.19 MHz and 424.01 MHz frequency ranges. The novelty lies in the possibility of mass-producing such a sensor using additive manufacturing will have a direct impact in the areas where conventional electronics cannot be utilized.
No More Political Compromise? Swedish Commissions of Inquiry 1990–2016

This article studies recent trends in the composition and uses of Swedish commissions of inquiry in preparing policy for the government. For much of the 20th century, commissions with representatives of major parliamentary parties and other policy stakeholders served as an arena of negotiation and compromise between the government, the opposition parties, and organised interests. Drawing on a unique data set of 2,087 commissions appointed between 1990 and 2016, we show that their representativeness has declined significantly. We also document a significant decrease in the inclusion of politicians and an increase in the presence of civil servants. Governments have also increased their control over commissions by issuing more directives. We further document a dramatic decline of reservations and dissenting opinions in the commission reports. This may be due to a combination of including fewer potentially dissenting voices and restricting commissions’ scope. We conclude that commissions are no longer the arenas of compromise- seeking that they were for most of the 20th century.
An Adaptive Detection Algorithm for Micro-grid Harmonic Power Based on Deep Belief Network

: There are many non-linear load devices in the micro-grid, resulting in a lot of complex harmonics, which is a key problem that leads to low measurement accuracy of electric energy metering devices. The traditional integrated empirical mode decomposition (EEMD) method can effectively deal with the problem of nonlinear and non-stationary signals, but this method has the problem of being highly dependent on artificial pre-set parameters. Here, the deep belief network (DBN) is introduced in the white noise signal generation process of EEMD. The main problems solved are as follows: one is to adaptively match the white noise signal according to the data characteristics of the current signal in the micro-grid, the other is to reduce the artificial setting error and make the separation result closer to the theoretical value. Finally, this paper uses the operating data in the actual environment to carry out experimental verification, and the results show that the error between the value of harmonic power in the production environment and the theoretical value given is reduced by 9.73%.
EDEM-FLUENT coupled simulation of coal-gas outburst two-phase flow

In the process of coal-gas outburst, the gas-solid two-phase flow of pulverized coal and gas will induce large-scale damage to underground mining. In this work, in order to study the dynamic evolution law of gas-solid two-phase flow of coal-gas outburst, and clarify the short-time destructive effect of outburst dynamic phenomenon, an EDEM-FLUENT coupled model is constructed to realize the numerical simulation of coal-gas outburst two-phase flow. The simulation results show that the flow velocity of pulverized coal in a short time (tens of milliseconds) approaches to the maximum velocity rapidly, which can reach 60 m/s. The velocity of pulverized coal is inversely proportional to the particle size. The initial acceleration of particles is slow, and then the acceleration increases rapidly. The accumulation angle of pulverized coal in the outburst hole is about 21° and is far less than the natural accumulation angle of pulverized coal, which is consistent with the general phenomenon of coal-gas outbursts. The results also show that the shock wave overpressure of the coal-gas outburst of numerical simulation is similar to that of the physical simulation test, and the difference is less than 10%. And the pressure change in the roadway is completed in short time. In terms of spatial relationships, the pressure at the position closest to the outburst mouth is not the maximum, and the maximum pressure exists at a certain position away from the outburst mouth.
