Data Acquisition And Processing

AbstractIn recent years, the permanent seismic networks worldwide have largely increased, raising the amount of earthquake signals and the applications using seismic records. Although characterization of the soil properties at recording stations has a large impact on hazard estimates, it has not been implemented so far in a standardized way for reaching high-level metadata. To address this issue, we built an online questionnaire for the identification of the indicators useful for a reliable site characterization at a seismic station. We analysed the answers of a large number of experts in different fields, which allowed us to rank 24 different indicators and to identify the most relevant ones: fundamental frequency (f0), shear-wave velocity profile (VS), time-averaged Vs over 30 m (VS30), depth of seismological and engineering bedrock (Hseis_bed and Heng_bed), surface geology and soil class. Moreover, the questionnaire proposed two additional indices in terms of cost and difficulty to obtain a reliable value of each indicator, showing that the selection of the most relevant indicators results from a complex balance between physical relevancy, average cost and reliability. For each indicator we propose a summary report, provided as editable pdf, containing the background information of data acquisition and processing details, with the aim to homogenize site metadata information at European level and to define the quality of the site characterization (see companion paper Di Giulio et al. 2021). The selected indicators and the summary reports have been shared within European and worldwide scientific community and discussed in a dedicated international workshop. They represent a first attempt to reach a homogeneous set of high-level metadata for site characterization.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by a lack of social communication and restrictive, repetitive behaviors or interests. This study aimed to examine the mealtime behaviors and food preferences of students with ASD. An online questionnaire on mealtime behavior and food preferences of ASD students was conducted by caregivers including parents, and the average age of ASD students was 14.1 ± 6.1. The analysis of mealtime behavior resulted in classification into three clusters: cluster 1, the “low-level problematic mealtime behavior group”; cluster 2, the “mid-level problematic mealtime behavior group”; and cluster 3, the “high-level problematic mealtime behavior group”. Cluster 1 included older students than other clusters and their own specific dietary rituals. Meanwhile, cluster 3 included younger students than other clusters, high-level problematic mealtime behavior, and a low preference for food. In particular, there were significant differences in age and food preference for each subdivided ASD group according to their eating behaviors. Therefore, the content and method of nutrition education for ASD students’ needs a detailed approach according to the characteristics of each group.

<b><i>Background:</i></b> The incidence of cutaneous melanoma, an important global public health problem, has been increasing over the last several decades. <b><i>Objectives:</i></b> In order to decrease melanoma-related mortality, ways to communicate and implement the correct methods for conducting primary and secondary prevention measures (such as early detection via self-examination) should be investigated. <b><i>Materials and Methods:</i></b> An observational, cross-sectional, retrospective study consisting of 409 patients diagnosed with cutaneous melanoma was conducted. An online questionnaire was created to evaluate knowledge levels, attitudes, and adherence to primary preventive measures and to skin self-examination practices. <b><i>Results:</i></b> The results revealed that even when 43% of the patients perform cutaneous self-examinations, only half of them fully followed the recommendations. Patients aged &#x3c;45 years, female, with a I–II phototype, with an intermediate/high level of education, and with a history of NMSC were more likely to have an adequate degree of knowledge. Moreover, patients aged &#x3c;45 years and with an adequate degree of knowledge more frequently showed an adequate adherence to the primary prevention measures. Finally, patients aged 45–60 years and with an adequate degree of knowledge presented a good adherence to the self-skin examination measures. <b><i>Limitations:</i></b> Possible limitations of this study were memory bias through the influence of age within the study population, and bias due to a greater proportion of subjects with a high education level. <b><i>Conclusion:</i></b> Within the population of patients with melanoma, a high percentage of patients do not rigorously follow the recommended prevention measures. Our study highlights the need to implement awareness in this population to improve the prevention of cutaneous cancer.

Nutrition And Dietetics

Beyond having a good degree, graduates are expected to have relevant skills and attributes required to compete and collaborate in a rapidly changing work environment. In recent times, the employability of Nutrition and Dietetics graduates in Nigeria has been of considerable concern. This study was designed to assess the readiness of trainees in the field of Nutrition and Dietetics from Nigerian Universities for career and work engagements. This descriptive cross-sectional study was carried out among 109 final-year undergraduate and postgraduate students from twelve universities offering Nutrition and Dietetics programme across Nigeria. Data was collected using a semi-structured online questionnaire. Data obtained were background information on the students, their experiences and challenges in their academic pursuits, willingness and readiness to pursue and engage in Nutrition and Dietetics related jobs, as well as their perception of skills and competences for future career and work engagements. The data were analysed using the IBM SPSS version 20.0. About 73% of the respondents were females, mainly between ages 21 and 25 years (62.4%) and undergraduates (70%). Among the undergraduate students, 83.4% had chosen to study Nutrition and Dietetics as a result of personal interest and choice while the postgraduate trainees indicated acquisition of in-depth knowledge of nutrition (60.6%) and quest to enhance career profile for competitive advantage in job pursuits (39.4%) as the core reasons for their choice for the programme. Nearly all the respondents (96.3%) reported having enjoyed their training programs. Only half (50.5%) perceived themselves to be “very ready” and well-prepared for work and career engagement. The top three areas of interest by trainees in Nutrition and Dietetics were Clinical Nutrition and Diet Therapy (60.6%), Community and Public Health Nutrition (43.1%), and Sports Nutrition (11.0%). Three out of every ten trainees had no specific desired skills and competences. While less than half declared that they had no knowledge of the skills and competences desired by employers of nutrition graduates, two-thirds of the trainees perceived themselves as eligible for their choice of work and career. This study shows that most Nutrition and Dietetics trainees in Nigerian universities are ready and willing to start a career in the field. However, many lack the knowledge of expected skills and competences needed for career engagement.

We show that it is possible to extend a general-purpose programming language with a convenient high-level data-type for manipulating XML documents while permitting (1) precise static analysis for guaranteeing validity of the constructed XML documents relative to the given DTD schemas, and (2) a runtime system where the operations can be performed efficiently. The system, named Xact, is based on a notion of immutable XML templates and uses XPath for deconstructing documents. A companion paper presents the program analysis; this paper focuses on the efficient runtime representation.

Abstract. Gamification is a rather new method in education and unfortunately is not a widely known method among Hungarian primary school teachers in Romania. This paper presents the knowledge and opinion of pre-service preschool and primary school teachers about gamification and its use in education. In this study 81 Primary and Preschool Pedagogy students from BabeșBolyai University were participated, 80 of them were female and 1 male. 40 students are in first year and 41 in second year of their studies. The research was carried out during February-March 2020 at Babeș-Bolyai University, Romania. To get to know their point of view and knowledge about gamification, an online questionnaire was developed by the authors. The obtained data was quantitatively (closed questions) and qualitatively (open questions) analyzed. According to the results, half of the students think that there is no difference between gamification and game-based learning and for three quarter it is difficult to see the differences. This is surprising as students were taught about gamification before filling in the questionnaire. Students perceive a high level of utility of gamification in education. The most frequently mentioned benefits by the participants are that gamification motivates and actively involves students. Even if participants gave many advantages of integrating gamification in education, the biggest disadvantage is related with the time necessary for preparation of a gamified lesson and for the time-allocation during the lesson. As obstacles of using gamification, they mentioned the negative attitude or/and lack of methodological knowledge of some teachers and the constrains of the curriculum. Most of the preservice teachers prefer both paper-pencil based and technology-aid gamification. They consider solving exercises the most suitable for gamification.

Abstract. Seismic records can provide detailed insight into the mechanisms of gravitational mass movements. Catastrophic events that generate long-period seismic radiation have been studied in detail, and monitoring systems have been developed for applications on a very local scale. Here we demonstrate that similar techniques can also be applied to regional seismic networks, which show great potential for real-time and large-scale monitoring and analysis of rockslide activity. This paper studies 19 moderate-sized to large rockslides in the Eastern Alps that were recorded by regional seismic networks within distances of a few tens of kilometers to more than 200 km. We develop a simple and fully automatic processing chain that detects, locates, and classifies rockslides based on vertical-component seismic records. We show that a kurtosis-based onset picker is suitable to detect the very emergent onsets of rockslide signals and to locate the rockslides within a few kilometers from the true origin using a grid search and a 1-D seismic velocity model. Automatic discrimination between rockslides and local earthquakes is possible by a combination of characteristic parameters extracted from the seismic records, such as kurtosis or maximum-to-mean amplitude ratios. We attempt to relate the amplitude of the seismic records to the documented rockslide volume and reveal a potential power law in agreement with earlier studies. Since our approach is based on simplified methods we suggest and discuss how each step of the automatic processing could be expanded and improved to achieve more detailed results in the future.
