Published: January 2024

Existing Graph Neural Network (GNN) training frameworks have been designed to help developers easily create performant GNN implementations. However, most existing GNN frameworks assume that the input graphs are static, but ignore that most real-world graphs are constantly evolving. Though many dynamic GNN models have emerged to learn from evolving graphs, the training process of these dynamic GNNs is dramatically different from traditional GNNs in that it captures both the spatial and temporal dependencies of graph updates. This poses new challenges for designing dynamic GNN training frameworks. First, the traditional batched training method fails to capture real-time structural evolution information. Second, the time-dependent nature makes parallel training hard to design. Third, it lacks system supports for users to efficiently implement dynamic GNNs. In this paper, we present NeutronStream, a framework for training dynamic GNN models. NeutronStream abstracts the input dynamic graph into a chronologically updated stream of events and processes the stream with an optimized sliding window to incrementally capture the spatial-temporal dependencies of events. Furthermore, NeutronStream provides a parallel execution engine to tackle the sequential event processing challenge to achieve high performance. NeutronStream also integrates a built-in graph storage structure that supports dynamic updates and provides a set of easy-to-use APIs that allow users to express their dynamic GNNs. Our experimental results demonstrate that, compared to state-of-the-art dynamic GNN implementations, NeutronStream achieves speedups ranging from 1.48X to 5.87X and an average accuracy improvement of 3.97%.
An Experimental Evaluation of Anomaly Detection in Time Series

Published: January 2024

Anomaly detection in time series data has been studied for decades in both statistics and computer science. Various algorithms have been proposed for different scenarios, such as fraud detection, environmental monitoring, manufacturing, and healthcare. However, there is a lack of comparative evaluation of these state-of-the-art approaches, especially in the same test environment and with the same benchmark, making it difficult for users to select an appropriate method for real-world applications. In this paper, we present a taxonomy of anomaly detection methods based on the main features, i.e., data dimension, processing technique, and anomaly type and six inner classes. We perform systematic intra- and inter-class comparisons of seventeen state-of-the-art algorithms on real and synthetic datasets with a point metric commonly used in classification problems and a range metric specifically designed for subsequence anomalies in time series data. We analyze the properties of these algorithms and test them in terms of effectiveness, efficiency, and robustness to anomaly rates, data sizes, number of dimensions, anomaly patterns, and threshold settings. We also test their performance in different use cases. Finally, we provide a practical guide for detecting anomalies in time series and discussions.
Quantum-Inspired Digital Annealing for Join Ordering
Authors: Schönberger Manuel , Trummer Immanuel , Mauerer Wolfgang
Published: January 2024

Finding the optimal join order (JO) is one of the most important problems in query optimisation, and has been extensively considered in research and practise. As it involves huge search spaces, approximation approaches and heuristics are commonly used, which explore a reduced solution space at the cost of solution quality. To explore even large JO search spaces, we may consider special-purpose software, such as mixed-integer linear programming (MILP) solvers, which have successfully solved JO problems. However, even mature solvers cannot overcome the limitations of conventional hardware prompted by the end of Moore's law.

We consider
quantum-inspired
digital annealing hardware, which takes inspiration from quantum processing units (QPUs). Unlike QPUs, which likely remain limited in size and reliability in the near and mid-term future, the digital annealer (DA) can solve large instances of mathematically encoded optimisation problems
today.
We derive a novel, native encoding for the JO problem tailored to this class of machines that substantially improves over known MILP and quantum-based encodings, and reduces encoding size over the state-of-the-art. By augmenting the computation with a novel readout method, we derive valid join orders for each solution obtained by the (probabilistically operating) DA. Most importantly and despite an extremely large solution space, our approach scales to practically relevant dimensions of around 50 relations and improves result quality over conventionally employed approaches, adding a novel alternative to solving the long-standing JO problem.
Kamel: A Scalable BERT-Based System for Trajectory Imputation
Authors: Musleh Mashaal , Mokbel Mohamed F.
Published: January 2024

Numerous important applications rely on detailed trajectory data. Yet, unfortunately, trajectory datasets are typically sparse with large spatial and temporal gaps between each two points, which is a major hurdle for their accuracy. This paper presents Kamel; a scalable trajectory imputation system that inserts additional realistic trajectory points, boosting the accuracy of trajectory applications. Kamel maps the trajectory imputation problem to
finding the missing word
problem; a classical problem in the natural language processing (NLP) community. This allows employing the widely used BERT model for trajectory imputation. However, BERT, as is, does not lend itself to the special characteristics of trajectories. Hence, Kamel starts from BERT, but then adds spatial-awareness to its operations, adjusts trajectory data to be closer to the nature of language data, and adds multipoint imputation ability to it; all encapsulated in one system. Experimental results based on real datasets show that Kamel significantly outperforms its competitors and is applicable to city-scale trajectories, large gaps, and tight accuracy thresholds.
An Efficient Transfer Learning Based Configuration Adviser for Database Tuning
Authors: Zhang Xinyi , Wu Hong , Li Yang , Tang Zhengju , Tan Jian , Li Feifei , Cui Bin
Published: January 2024

In recent years, a wide spectrum of database tuning systems have emerged to automatically optimize database performance. However, these systems require a significant number of workload runs to deliver a satisfactory level of database performance, which is time-consuming and resource-intensive. While many attempts have been made to address this issue by using advanced search optimizers, empirical studies have shown that no single optimizer can dominate the rest across tuning tasks with different characteristics. Choosing an inferior optimizer may significantly increase the tuning cost. Unfortunately, current practices typically adopt a single optimizer or follow simple heuristics without considering the task characteristics. Consequently, they fail to choose the most suitable optimizer for a specific task. Furthermore, constructing a compact search space can significantly improve the tuning efficiency. However, current practices neglect the setting of the value range for each knob and rely on a large number of workload runs to select important knobs, resulting in a considerable amount of unnecessary exploration in ineffective regions.

To pursue efficient database tuning, in this paper, we argue that it is imperative to have an approach that can judiciously determine a precise space and search optimizer for an arbitrary tuning task. To this end, we propose OpAdviser, which exploits the information learned from historical tuning tasks to guide the search space construction and search optimizer selection. Our design can greatly accelerate the tuning process and further reduce the required workload runs. Given a tuning task, OpAdviser learns the geometries of search space, including important knobs and their effective regions, from relevant previous tasks. It then constructs the target search space from the geometries according to the on-the-fly task similarity, which allows for adaptive adjustment of the target space. OpAdviser also employs a pairwise ranking model to capture the relationship from task characteristics to optimizer rankings. This ranking model is invoked during tuning and predicts the best optimizer to be used for the current iteration. We conduct extensive evaluations across a diverse set of workloads, where OpAdviser achieves 9.2% higher throughput and significantly reduces the number of workload runs with an average speedup of ~3.4x compared to state-of-the-art tuning systems.

Published: January 2024

Feature stores (also sometimes referred to as embedding stores) are becoming ubiquitous in model serving systems: downstream applications query these stores for auxiliary inputs at inference-time. Stored features are derived by
featurizing
rapidly changing base data sources. Featurization can be costly prohibitively expensive to trigger on every data update, particularly for features that are vector embeddings computed by a model. Yet, existing systems naively apply a one-size-fits-all policy as to when/how to update these features, and do not consider query access patterns or impacts on prediction accuracy. This paper introduces RALF, which orchestrates feature updates by leveraging
downstream error feedback
to minimize
feature store regret
, a metric for how much featurization degrades downstream accuracy. We evaluate with representative feature store workloads, anomaly detection and recommendation, using real-world datasets. We run system experiments with a 275,077 key anomaly detection workload on 800 cores to show up to a 32.7% reduction in prediction error or up to 1.6X compute cost reduction with accuracy-aware scheduling.
MOSER: Scalable Network Motif Discovery Using Serial Test
Authors: Najafi Mohammad Matin , Ma Chenhao , Li Xiaodong , Cheng Reynold , Lakshmanan Laks V. S.
Published: January 2024

Given a graph
G
, a motif (e.g., 3-node clique) is a fundamental building block for
G.
Recently, motif-based graph analysis has attracted much attention due to its efficacy in tasks such as clustering, ranking, and link prediction. These tasks require Network Motif Discovery (NMD) at the early stage to identify the motifs of
G.
However, existing NMD solutions have two drawbacks: (1) Lack of theoretical guarantees on the quality of the samples generated using the existing methods, and (2) inefficient algorithms, which are not scalable for large graphs. These limitations hinder the exploration of motifs for analyzing large graphs. To address the above issues, we propose a novel solution named MOSER (
MO
tif Discovery using
SER
ial Test). This novel NMD framework leverages a significance testing method known as the serial test, which differs from the existing solutions. We further propose two fast incremental subgraph counting algorithms, allowing MOSER to scale to larger graphs than ever possible before. Extensive experimental results show that using MOSER can improve the state-of-the-art up to 5 orders of magnitude in efficiency and that the motifs found by MOSER facilitate downstream tasks such as link prediction.
Co-Movement Pattern Mining from Videos

Published: January 2024

Co-movement pattern mining from GPS trajectories has been an intriguing subject in spatial-temporal data mining. In this paper, we extend this research line by migrating the data source from GPS sensors to surveillance cameras, and presenting the first investigation into co-movement pattern mining from videos. We formulate the new problem, re-define the spatial-temporal proximity constraints from cameras deployed in a road network, and theoretically prove its hardness. Due to the lack of readily applicable solutions, we adapt existing techniques and propose two competitive baselines using Apriori-based enumerator and CMC algorithm, respectively.

As the principal technical contributions, we introduce a novel index called temporal-cluster suffix tree (TCS-tree), which performs two-level temporal clustering within each camera and constructs a suffix tree from the resulting clusters. Moreover, we present a sequence-ahead pruning framework based on TCS-tree, which enables the concurrent utilization of all pattern constraints to filter candidate paths. Finally, to reduce verification cost on the candidate paths, we propose a sliding-window based co-movement pattern enumeration strategy and a hashing-based dominance eliminator, both of which are effective in avoiding redundant operations.

We conduct extensive experiments for scalability and effectiveness analysis. Our results validate the efficiency of the proposed index and mining algorithm, which runs remarkably faster than the two baseline methods. Additionally, we construct a video database with 1169 cameras and perform an end-to-end pipeline analysis to study the performance gap between GPS-driven and video-driven methods. Our results demonstrate that the derived patterns from the video-driven approach are similar to those derived from groundtruth trajectories, providing evidence of its effectiveness.

Published: January 2024

The cultivation of passion fruit requires constantly updated technical information to achieve competitive results. In this context, a commonly discussed aspect is the development of vigorous seedlings. The aim of this study was to assess water depletion levels in a substrate (WDL) and TerraCottem® doses for the formation of yellow passion fruit seedlings. The experimental design used was split plots in a completely randomized design, with four replications. The treatments consisted of 5, 15, 25, 35% of NDA and 0, 2.5, 5.0, 7.5, and 10.0 kg m-3 of TerraCottem® doses. The following variables were measured: plant height (PH), stem diameter (SD), number of leaves (NL), dry biomass of the aerial part (DSB), root system (DRS), total dry biomass (TDM), and the Dickson Quality Index (DQI) was calculated. WDL treatments did not influence the evaluated variables. NL, PH, SD, DSB, DSR, TDM, and DQI showed increases of 12.3, 13.4, 10.0, 30.1, 28.1, 29.5, and 26.8%, respectively, when comparing the highest TerraCottem® dose to the control treatment. Sliced interaction showed double gains for the highest TerraCottem® dose for SD and PH. The plants responded to higher doses of TerraCottem®, indicating synergy of the water-retaining polymer in the plant's water supply, especially in the presence of higher WDL.

Published: January 2024

Knowing the phenology, production, and fruit quality of blackberry cultivars grown in greenhouses enables growers to develop and/or improve assertive orchard management. The aim of this study was to investigate whether phenology, production, and fruit quality differ among blackberry cultivars grown under greenhouse. The treatments were four blackberry cultivars (‘BRS Cainguá’, ‘BRS Tupy’, ‘BRS Xavante’, and ‘BRS Xingu’), arranged in a randomized block design, with four replications and three plants per plot. Phenology, production, and fruit quality were assessed. ‘BRS Xingu’ had an earlier start than all the phenological stages assessed, proving to be the earliest to achieve fruit harvest stage. ‘BRS Cainguá’ was the latest to harvest. ‘BRS Xingu’ showed the highest total production values, followed by ‘BRS Cainguá’, with the largest longitudinal diameter, and ‘BRS Tupy’, with the largest transverse diameter. Fruit quality was not influenced by the cultivars. In conclusion, the four blackberry cultivars differ in terms of phenology and fruit production potential under greenhouse. This allows production to be staggered around 15 days in terms of the start and end of the harvest.

Published: January 2024

This study aimed to evaluate the impact of various soil preparation practices, rainfall intensities and slopes using a rainfall simulator. Three land preparation methods (mulching, terracing, and terracing + ditches), three rainfall intensities (18, 50, and 73 mm h−1), and three slopes (5, 10, and 15%) were examined to verify best practices of soil preparation. The exclusive use of straw (10 Mg ha-1) on the surface is insufficient to prevent runoff and consequently the loss of water and soil on steep terrain and subject to high-intensity rainfall. The combination of terracing + ditches proved to be effective in reducing runoff. This study has substantial implications for the control of soil erosion for the sustainable development of agriculture in subtropical conditions.

Published: January 2024

Reduced heart rate variability (HRV) and fatigue are common after COVID‐19 infection and both are potentially influenced by physical activity (PA). We compared resting HRV, PA from accelerometers and questionnaires, and self‐reported fatigue in 41 COVID‐19 survivors (~8 months postinfection, 38 ± 17 years) with 41 matched controls. Differences in HRV were observed on acceleration capacity (p = 0.041), deceleration capacity (p = 0.032), high‐frequency peak frequency (p = 0.019), absolute low‐frequency power (p = 0.042), relative very low‐frequency power (p = 0.012), SD2 (from Poincare plot; p = 0.047), and DFA2 (slope of long‐term detrended fluctuation analysis; p = 0.004). Fatigue was greater in COVID‐19 survivors (p < 0.001) with no differences in PA. Moderate‐vigorous physical activity (MVPA) (Standardized Beta = −0.427, p = 0.003) and steps per day (Standardized Beta = −0.402, p = 0.007) were associated with DFA2 in COVID‐19 survivors after controlling for age, sex, and body fat percentage. Fatigue was correlated to less MVPA (Spearman's rho = 0.342, p = 0.031) and fewer steps per day (rho = 0.329, p = 0.038) in COVID‐19 survivors, and was indirectly linked to HRV through these PA mediators (Estimate = −0.20; p = 0.040). We present a model showing the complex relations between HRV, PA, and fatigue that provides the foundation for strategies to improve outcomes and rehabilitation after COVID‐19 infection.
Influence of vibratory conveyor design parameters on the trough motion and the self-synchronization of inertial vibrators
Authors: Cieplok Grzegorz
Published: January 2024

A spatial model of a vibratory conveyor supported on steel-elastomer vibration isolators and vibrated by two inertial vibrators is presented in this article. The results of analyses of the effect of the layout of vibrators on the operation of the conveyor are presented. Displacement of the line of action of vibrators resultant force beyond the machine mass center causes the drift of the trough movement from the desirable rectilinear motion and problems associated with the unevenness of material movement. Three main cases were analyzed in the article: the displacement of the center of mass of the machine body from the straight line of action of the resultant for the vibrators, rotation of the main axes of inertia of the conveyor body in the working plane of the conveyor, and the oblique-angular resonance. The model presented in this article is used to consider coupling between vibrators and the body of the machine, which is responsible for the process of self-synchronization of the vibrators and the correctness of machine operation. The results of the theoretical analyses presented in this article were verified by laboratory tests and references to observations based on the authors’ industrial experience.
Comparison of the traditional and block mode of delivery on undergraduate nursing students’ perceived levels of preparedness to use evidence-based practice: a two-group experimental study
Authors: Burton Trish A. , Gauci Sally A. , Heslop Liza M. , Andrew Sharon J.
Published: January 2024

Objectives

To examine how delivery time impacted on undergraduate nursing students’ preparedness for evidence-based practice (EBP) by comparing the traditional semester mode and block mode of delivery models.

Methods

This two-group experimental study compared the traditional semester and block modes of delivery using a self-reported questionnaire. The factor of time was the variable in relation to learning with the block mode delivery being in a compressed timeframe.

Results

From a purposive sample, 219 students participated in the self-reported questionnaire. There were only two significant differences were the block mode of delivery students responded less positively to the statements ‘the unit of study prepared them for knowledge and skills for EBP’ and ‘EBP should be discussed and shared in practice’.

Conclusions

The transition from the traditional semester mode to the block mode delivery has had minimal impact on undergraduate nursing students’ perceptions of EBP and its application to clinical practice.
Image feature extraction algorithm based on visual information

Published: January 2024

Vision is the main sensory organ for human beings to contact and understand the objective world. The results of various statistical data show that more than 60% of all ways for human beings to obtain external information are through the visual system. Vision is of great significance for human beings to obtain all kinds of information needed for survival, which is the most important sense of human beings. The rapid growth of computer technology, image processing, pattern recognition, and other disciplines have been widely applied. Traditional image processing algorithms have some limitations when dealing with complex images. To solve these problems, some scholars have proposed various new methods. Most of these methods are based on statistical models or artificial neural networks. Although they meet the requirements of modern computer vision systems for feature extraction algorithms with high accuracy, high speed, and low complexity, these algorithms still have many shortcomings. For example, many researchers have used different methods for feature extraction and segmentation to get better segmentation results. Scale-invariant feature transform (SIFT) is a description used in the field of image processing. This description has scale invariance and can detect key points in the image. It is a local feature descriptor. A sparse coding algorithm is an unsupervised learning method, which is used to find a set of “super complete” basis vectors to represent sample data more efficiently. Therefore, combining SIFT and sparse coding, this article proposed an image feature extraction algorithm based on visual information to extract image features. The results showed that the feature extraction time of X algorithm for different targets was within 0.5 s when the other conditions were the same. The feature matching time was within 1 s, and the correct matching rate was more than 90%. The feature extraction time of Y algorithm for different targets was within 2 s. The feature matching time was within 3 s, and the correct matching rate was between 80 and 90%, indicating that the recognition effect of X algorithm was better than that of Y algorithm. It indicates the positive relationship between visual information and image feature extraction algorithm.
Polyvinylpyrrolidone-stabilised gold nanoparticle coatings inhibit blood protein adsorption
Authors: Tiyyagura Hanuma Reddy , Rudolf Rebeka , Bracic Matej
Published: January 2024

In this work, the ability of polyvinylpyrrolidone (PVP)-stabilised gold nanoparticle (AuNP) coatings to inhibit blood protein adsorption was evaluated by studying time-resolved solid–liquid interactions of the coatings with the model blood protein bovine serum albumin (BSA). Inhibiting unspecific blood protein adsorption is of crucial importance for blood-contacting implant devices, e.g. vascular grafts, stents, artificial joints, and others, as a preventive strategy for bacterial biofilm formation. A quartz crystal microbalance was used in this work to coat the AuNPs on piezoelectric sensors and to follow time-resolved solid–liquid interactions with the proteins. The AuNP coatings were evaluated for their wettability by contact angle measurements, their surface morphology by light- and atomic force microscopy, and their chemical composition by energy-dispersive X-ray spectroscopy. Results revealed a homogeneous distribution of AuNPs on the sensor surface with a dry mass coverage of 3.37 ± 1.46 µg/cm2 and a contact angle of 25.2 ± 1.1°. Solid–liquid interaction studies by quartz crystal microbalance showed a high repellence of BSA from the PVP-stabilised AuNP coatings and the importance of the PVP in the mechanism of repellence. Furthermore, the conformation of the polymer on the coatings as well as its viscoelastic properties were revealed. Finally, the activated partial thrombin time test and fibrinogen adsorption studies revealed that the AuNPs do not accelerate blood coagulation and can partially inhibit the adhesion of fibrinogen, which is a crucial factor in the common blood coagulation cascade. Such AuNPs have the potential to be used in blood-contact medical applications.
FSLSM-Based Analysis of Student Performance Information in a Blended Learning Course Using Moodle LMS
Authors: Ait Daoud Mohammed , Namir Abdelwahed , Talbi Mohammed
Published: January 2024

Over the past decades, blended learning using a flipped classroom approach has become an increasingly important part of global learning development and has gradually revolutionized educational environments. However, in the online part, individual differences of learners are often not considered and treated in an equipollent way, neglecting their needs and personal characteristics, which results in a poor quality of the learning service. Thus the need to improve both the content of e-learning systems and their adaptability requires a careful examination of the direct behavior of students in distance learning platforms. Our study is based on a dataset from the FOAD_FSBM e-learning platform involved in the learning of Moroccan university students. This work is motivated by the fact that professors seek to better understand students’ learning styles, which are founded on the Felder and Silverman Learning Style Model (FSLSM) so that they can offer them adaptive and personalized courses. In this article, we first describe the basic environment of this study and the reasons that led us to choose the Moodle e-learning platform. We also present the format of the courses created to conduct our experiments, and its advantage in e-learning. Then, we highlight the development tools that we used to conduct our studies. Finally, we present the results of our statistical analyses in relation to the performance of the students.

Resumen: Durante las urgencias y emergencias se producen situaciones de vulnerabilidad y desprotección de las personas afectadas y son, en ocasiones, el foco de la problemática social. El presente artículo, a través de tres informantes clave: una enfermera del Servicio de Atención Médica Urgente (SAMU) del SES de la Comunitat Valenciana de la unidad A101 de Gandía, un Policía Local de Gandía y la directora de Servicios Sociales del Ayuntamiento de Gandía; trata de valorar la necesidad de implantar un Servicio de Atención a Urgencias Psicosociales formado por trabajadores/as sociales y psicólogos/as que trabaje las 24 horas, los 365 días al año en conjunto con el Servicio de Atención a urgencias Psicosociales en la localidad valenciana de Gandía. Los resultados reflejan que la atención integral junto con servicios de atención a urgencias psicosociales no es todavía una realidad en Gandía, a diferencia de otras ciudades de España. La implantación de un Servicio de Atención a Urgencias Psicosociales que funcione 24h/365 días en Gandía requiere la voluntad de políticos y de los profesionales implicados, recursos económicos y recursos materiales, siendo el principal beneficiario de esta iniciativa el ciudadano.

One of the fundamental purposes of the human being is to develop a full and meaningful life. Among the main sources to achieve this meaning in life is social support.  Meaning in life is essential because, in addition contributes to achieving resilient coping with adversities that occur throughout life. This is a relevant research issue for social work and other social sciences. It involved 1,500 participants from Argentina, Colombia, Spain and Indonesia, who completed a booklet comprising Morgan and Farsides' (2009a, 2009b) Meaningful Life Measure (MLM), the Medical Outcome Study-Social Support Survey (MOS-SSS) by Sherbourne and Stewart (1991) and Connor-Davidson’s (2003) Resilience Scale (CD-RISC). The scales used have good psychometric properties. The factor analysis finds a five-factor structure for the meaning in life scale and two factors for the social support scale, while the resilience scale behaves as a unifactorial one. The structural model shows that social support influences both meaning in life and resilience in the face of adversity. A direct influence of social support on resilience is also observed.

Entre justice et administration: la cour des aides de Montauban contre l'intendant lors des crises de l'Ancien Régime français
Authors:   Université de Toulouse 1 Capitole (Toulouse 1 Capitole University, France), Mengès-Le Pape Christine
Published: January 2024

The relations between the sovereign courts and the intendants contain a tormented and unsuccessful history, marked since the Grand Siècle by the difficult passage from the traditional jurisdictional management of the kingdom, considered inefficient, to an organisation that supports the triumph of the absolute and administrative monarchy. In these southern lands of the kingdom of France, torn apart by the Protestant reformation and the wars, the institutional upheaval which prepared the modern state and the Napoleonic granite masses, was carried out through strong embarrassments which opposed the intendant of the generality to the court of aids in Montauban. As soon as they were created, the magistrates of the jurisdictional company multiplied the manoeuvres against the intendant to safeguard their contentious attributions and the control of the municipal funds. Their particularistic actions were denounced by the intendant, who was there to make the king present everywhere in the kingdom and was zealous in his service. Since then, all the elements were in place for the outbreak of a noisy quarrel – the lawsuit against the intendant Gaspard Lescalopier – which worried the government at the turn of the reign of Louis XV, in the middle of the tax war in 1749, when King Louis XV, whom the subjects looked upon as a charming prince, became „Louis the Unloved”. These tumults prevented the modernisation of the French monarchy and led to the troubles of the Revolution.

The Roman Empire entered a period of rapid romanization of the Roman provinces in the 2nd century AD. This also took place, with varying intensity, in African provinces. An expression of this was the granting of Roman citizenship to the leaders of indigenous tribes. The document called Tabula Banasitana, an epigraphic find discovered in the 20th century at the site of the ancient civitas Banasa, documents the process of granting Roman law to the leaders of the Zegrenses tribe and their families. The Roman ius civile was granted to them with the preservation of the rights of their people and without exemptions from public burdens. The author analyzes three documents engraved as an inscription known as Tabula Banasitana, concerning the romanization of the province Mauretania Tingitana. The article describes the process of the gradual incorporation of the North-West African tribal leaders into the structures of the Roman province of Mauretania. Sometimes members of the local elites were granted the status of Roman citizen by the Roman authorities, even though they retained all privileges derived from native law. Through this balanced social policy, Rome was able to keep the peace in frontier areas of the Empire, which were threatened by conflicts with neighbors or, as in this case, nomadic tribes. This form of Roman citizenship was limited – the nature and extent of the restrictions depended on the relationship between the person receiving citizenship and the local community or the Empire’s fiscal interests (for example new citizens were not relieved of obligations like tributum or vectigal). Citizenship was usually granted viritim, but sometimes – as Tabula Bansitana shows – members of the newly minted citizen’s family (wife and children) also received the privilege.

Lighting of plant crops (phytolighting) realized on the basis of LEDs has revolutionized the field of indoor agriculture and cultivation of crops in closed controlled environments due to the possibility of optimizing the spectral composition and high energy efficiency. The use of specialised quasi-monochromatic radiation allows the activation of specific photomorphogenic, biochemical or physiological responses in plants, while LED radiation of a specific spectral composition (e.g. UV radiation) allows the control of plant pests and diseases. The literature review indicates that there is a species- and cultivar-specific response of plants to light radiation of a particular spectral composition and that this response varies with the stage of plant development, the intensity of illumination, the duration of plant development and specific interactions with the environment. Based on the developed recommendations for the spectral composition of radiation intended for plant illumination, the requirements for the spectral composition of light for phytolighting systems were determined. The efficiency of LEDs with different spectral compositions for plant illumination and the most energy efficient LEDs for use in phytolighting systems were determined. Special software was developed to determine the photon radiation efficiency and it was determined for a wide range of LED light sources. The LEDs studied had photon efficiencies ranging from 3.78 μmol/J (quasi-monochromatic blue LEDs) to 5.46 μmol/J (quasi- monochromatic red LEDs). White LEDs, depending on their colour rendering index, had a photon spectral efficiency in the range of 4.62-4.79 μmol/J. Some modern white LEDs with a high colour rendering index have a photon spectral efficiency close to that of phytolighting based on special quasi-monochromatic LEDs, but their efficiency, taking into account the weighting factor of the use of photons of different wavelengths for photosynthesis, is much lower.

The results of studies of the energy efficiency and functional parameters of non-directional LED lamps for replacing incandescent lamps, which are supplied to Ukraine as aid for reducing electricity costs for lighting in the residential sector, and their compliance with the new requirements of the Commission Regulation (EU) 2019/2020 on establishing requirements are presented to ecodesign for light sources and Commission Delegated Regulation (EU) 2019/2015 on energy labeling of light sources, which entered into force in EU countries in 2021. In Ukraine, national technical regulations are being developed on the basis of these regulations. The following parameters of LED lamps with a power of 5-12 W were measured: power consumption, power factor, useful luminous flux, correlated color temperature, uniformity of color, color rendering index, short-term indicator of light flickering, indicator of the visibility of the stroboscopic effect, coefficient of preservation of luminous flux after 3000 hours of operation of the lamps and others The maximum power allowed by the Regulation was calculated, which is defined as a function of the declared useful luminous flux and the declared color rendering index, as well as energy efficiency classes in accordance with the requirements of the new energy labeling, the service life of the lamps was estimated according to the experimentally determined coefficient of preservation of the luminous flux and according to the data of the service life declared by the manufacturer. It is shown that most of the parameters of LED lamps entering Ukraine meet the requirements of the new Commission (EU) Regulations and despite the identified inconsistencies among individual manufacturers, there have been successes in increasing the energy efficiency and quality of LED lamps over the last decade. Keywords: Commission Regulations (EU), LED light sources, energy efficiency, functional parameters.
Seis diseños didácticos para el aprendizaje de la materia de filosofía mediante el desarrollo de habilidades: el caso de dos centros educativos de secundaria públicos en San José, Costa Rica
Authors: Cordero Redondo Joan Javier
Published: January 2024

Las investigaciones contemporáneas sobre la enseñanza de la filosofía son amplias, sin embargo, en la mayoría de los casos esas investigaciones no aportan al acervo de la enseñanza y los diseños didácticos comprobados. El objetivo de esta investigación es analizar los límites y alcances del diseño didáctico y metodológico para enseñar filosofía en secundaria, en consideración del paradigma de educación por habilidades (Assessment and Teaching of 21st Century Skills, 2010; Griffin et al., 2012) en el marco de la estrategia Aprendo en casa, del Ministerio de Educación Pública, durante el curso lectivo 2020, en el Liceo José Joaquín Vargas Calvo y Liceo Sinaí, San José, Costa Rica. Entre los aspectos metodológicos, esta investigación es de enfoque cualitativo con estudio de caso. Se plantea: 1) las generalidades del escenario educativo de las personas participantes, 2) el perfil profesional de la persona docente y 3) la valoración de los diseños didácticos y la filosofía; para lo cual se aplica una entrevista estructurada a 100 personas estudiantes. Entre los resultados más oportunos está la creación y validación positiva de 6 diseños didácticos para enseñar y aprender filosofía en la secundaria. Entre las conclusiones, se destaca que el paradigma sobre el que se basan los diseños didácticos filosóficos procura alentar la autonomía del pensamiento de la persona estudiante, la construcción de aprendizaje y el desarrollo de habilidades, constituyendo esto un manual sugestivo de actividades didácticas filosóficas para el trabajo pedagógico cotidiano dentro del paradigma de la educación por habilidades. Se recomienda explorar la aplicación de estos diseños didácticos en grupos de otros grados escolares e indagar sobre nuevos diseños didácticos de filosofía basados en la educación por habilidades.
Motivaciones de ingreso de estudiantes de pedagogía: caso de una universidad del norte de Chile

El objetivo del presente estudio es dar a conocer las principales motivaciones de las y los estudiantes que ingresan a pedagogía en una universidad del norte de Chile, recopilados en tres cohortes distintas en los años 2016, 2018 y 2022. El estudio se encuentra situado en el paradigma cuantitativo, con un alcance descriptivo y se utiliza como referencia el estudio de caso como metodología de análisis y justificación de los datos. El instrumento de recolección de información es una adaptación del original aplicado en el año 2007 y fue validado por un panel de expertos. La configuración del instrumento permite determinar las principales motivaciones para los estudios de pedagogía e indagar sobre otros no recolectados anteriormente. Su aplicación se realizó a un total de 7 pedagogías distintas, con una participación de más del 80% del estudiantado de cada carrera. En cuanto a la caracterización de la muestra, se destaca el género femenino mayoritariamente en el ingreso a pedagogía, personas estudiantes que viven dentro de la misma región de la institución y con puntajes sobre los 500 puntos PSU (Prueba Selección Universitaria), lo cual configura un perfil estudiantil de primer año. Los resultados muestran una tendencia clara en los tres años de su aplicación destacándose: El gusto por la especialidad de mi carrera, seguido de Me gustaba la idea de trabajar con niños y/o jóvenes, Me gustaba la enseñanza y Deseaba ayudar a los demás mediante el ejercicio de la docencia. Estas categorías se relacionan con otros estudios de la temática, en años y contextos diversos, por lo cual al parecer existen motivaciones comunes en el interés por la pedagogía. Contar con esta información ofrece una oportunidad a la institución para el levantamiento de acciones de retención de personas estudiantes orientadas a las motivaciones y a la captación de futuros y futuras docentes, pero así también a profundizar en la temática considerando otras variables como por ejemplo si existe variación del interés de acuerdo con el área disciplinar, los diferentes años que cursan la carrera o la trayectoria profesional.
