Published: May 2023

In view of the requirements on control precision of autonomous underwater vehicles (AUVs) in different operations, the improvement of AUV motion control accuracy is the focus of this paper. In regard to the unsatisfying robustness of traditional control methods, an interactive network based on Least Square Support Vector Regression (LSSVR) is therefore put forward. The network completed the identification of the strong nonlinear AUV dynamic characteristics based on the LSSVR theory and by virtue of the interactions between the offline and online modules, it achieved offline design and online optimization of the AUV control law. In addition to contrastive numerical simulations and sea trials with the classic S-plane method in AUV velocity and heading control, the LSSVR network was also tested in path following and long-range cruise. The precision and robustness and of the proposed network were verified by the high-accuracy control results of the aforesaid simulations and trials. The network can be of practical use in AUV control especially under unfamiliar water conditions with access to a limited number of control samples or little information of the operation site.

Published: May 2023

Several inputs of metal contamination can affect port seawater, such as industries and sludges. Despite the urge of developing new techniques to face this problem, most of the studies focus on traditional methods of remediation. Bioremediation by fungi represents an innovative and sustainable tool to efficiently remove metals from seawaters. The study’s aim is to develop a new green technology using fungi (myco-barriers) to maintain a good standard for water quality in port areas. A large commercial port (Port of Genoa) and a small marina (Port of Cavo) in Italy were chosen as pilot sites. Myco-barriers were realised by inoculating sterile straw and sawdust with mycelium of macro- and microfungi. After the incubation, myco-barriers were placed in the ports and sampled after 15 and 30 days to verify metal bioaccumulation. Myco-barriers with macrofungi showed the tendency to bioaccumulate more efficiently after 15 treatment days (Zn 7.0 mg kg−1, Cu 6.5 mg kg−1, Pb 1.2 mg kg−1), while myco-barriers with microfungi showed higher bioaccumulation after 30 days (Ni 0.6 mg kg−1, Pb 0.6 mg kg−1, Cu 5 mg kg−1). Results showed that myco-barriers have metal bioaccumulation potential and can represent a significant alternative to traditional techniques of remediation (chemical–physical).

Published: May 2023

This paper aims to analyze factors that influence social performance-related information disclosure in European countries. Specifically, the objective is to investigate the Board’s attributes (Diversity, Inclusion, People Development and Controversies). To achieve the goal, an empirical analysis was conducted with 2494 listed companies in Europe as support for the economic year 2021. To measure a possible link between the variables under study, a regression analysis was performed. Our results show that Board Diversity, Inclusion and People Development contribute positively to social performance disclosure, whereas Board Controversies negatively affect the dependent variable. Furthermore, the study results reveal that the country’s legal system is relevant to the company’s transparency. The model variables determine 62% of the social performance reporting variance. Our Results are useful for all non-financial information users, governments and organizations in developing sustainability reporting standards.

Published: May 2023

The induction motor (IM) drives are prone to various uncertainties, disturbances, and non-linear dynamics. A high-performance control system is essential in the outer loop to guarantee the accurate convergence of speed and torque to the required value. Super-twisting sliding mode control (ST-SMC) and fractional-order calculus have been widely used to enhance the sliding mode control (SMC) performance for IM drives. This paper combines the ST-SMC and fractional-order calculus attributes to propose a novel super-twisting fractional-order sliding mode control (ST-FOSMC) for the outer loop speed control of the model predictive torque control (MPTC)-based IM drive system. The MPTC of the IM drive requires some additional sensors for speed control. This paper also presents a novel machine learning-based Gaussian Process Regression (GPR) framework to estimate the speed of IM. The GPR model is trained using the voltage and current dataset obtained from the simulation of a three-phase MPTC based IM drive system. The performance of the GPR-based ST-FOSMC MPTC drive system is evaluated using various test cases, namely (a) electric fault incorporation, (b) parameter perturbation, and (c) load torque variations in Matlab/Simulink environment. The stability of ST-FOSMC is validated using a fractional-order Lyapunov function. The proposed control and estimation strategy provides effective and improved performance with minimal error compared to the conventional proportional integral (PI) and SMC strategies.

Published: May 2023

The aim of the current study was to investigate the prevalence of Clostridium perfringens (C. perfringens) recovered from animal faeces, as well as to determine the antimicrobial susceptibility of such isolates. A total of 14 (14/100; 14%) C. perfringens isolates were isolated from the 100 analysed samples (twelve recovered from faecal samples collected from pigs and two from veal calves’ faecal samples). The preponderant genotype was type A, with all isolates being cpa-positive. The most potent antimicrobial agents against C. perfringens proved to be vancomycin, rifampicin and lincomycin. A strong resistance to tetracycline (71.4%), penicillin (64.2%), erythromycin (42.8%) and enrofloxacin (35.7%) was also observed. To the best of our knowledge, this is the first analysis regarding the prevalence, characterization and antimicrobial susceptibility of C. perfringens in food-producing animals in Romania, adding further evidence for the probable role of animals as a source of resistant C. perfringens strains.
RNase Y Autoregulates Its Synthesis in Bacillus subtilis
Authors: Korobeinikova Anna , Laalami Soumaya , Berthy Clément , Putzer Harald
Published: May 2023

The instability of messenger RNA is crucial to the control of gene expression. In Bacillus subtilis, RNase Y is the major decay-initiating endoribonuclease. Here, we show how this key enzyme regulates its own synthesis by modulating the longevity of its mRNA. Autoregulation is achieved through cleavages in two regions of the rny (RNase Y) transcript: (i) within the first ~100 nucleotides of the open reading frame, immediately inactivating the mRNA for further rounds of translation; (ii) cleavages in the rny 5′ UTR, primarily within the 5′-terminal 50 nucleotides, creating entry sites for the 5′ exonuclease J1 whose progression is blocked around position −15 of the rny mRNA, potentially by initiating ribosomes. This links the functional inactivation of the transcript by RNase J1 to translation efficiency, depending on the ribosome occupancy at the translation initiation site. By these mechanisms, RNase Y can initiate degradation of its own mRNA when the enzyme is not occupied with degradation of other RNAs and thus prevent its overexpression beyond the needs of RNA metabolism.
O-Polysaccharides of LPS Modulate E. coli Uptake by Acanthamoeba castellanii
Authors: Liu Ying , Koudelka Gerald
Published: May 2023

Protozoan grazing is a major cause of bacterial mortality and controls bacterial population size and composition in the natural environment. To enhance their survival, bacteria evolved many defense strategies to avoid grazing by protists. Cell wall modification is one of the defense strategies that helps bacteria escape from recognition and/or internalization by its predators. Lipopolysaccharide (LPS) is the major component of Gram-negative bacterial cell wall. LPS is divided into three regions: lipid A, oligosaccharide core and O-specific polysaccharide. O-polysaccharide as the outermost region of E. coli LPS provides protection against predation by Acanthamoeba castellanii; however, the characteristics of O-polysaccharide contribute to this protection remain unknown. Here, we investigate how length, structure and composition of LPS affect E. coli recognition and internalization by A. castellanii. We found that length of O-antigen does not play a significant role in regulating bacterial recognition by A. castellanii. However, the composition and structure of O-polysaccharide play important roles in providing resistance to A. castellanii predation.
Influence of Low-Temperature Hydrothermal Events and Basement Fault System on Low-Resistivity Shale Reservoirs: A Case Study from the Upper Ordovician to Lower Silurian in the Sichuan Basin, SW China

High graphitization is responsible for low-resistivity shale development with poor reservoir quality. This paper provides an explanation of organic matter graphitization and determines the impact of high graphite content on low-resistivity shale reservoir quality at the Wufeng-Longmaxi Formation in the Southern Sichuan Basin. Fine veins are frequently developed at shale samples with Ro > 3.5%, graphitized organic matter > 25%, and resistivity < 5 Ω•m, which are dominated by three mineral assemblages: brunsvigite, barite-hyalophane-barium feldspar-potassium feldspar-anhydrite, and calcite-ankerite. These filling minerals are characterized by an Eu positive anomaly and high Ba, Fe, and Mn contents, suggesting that low-resistivity shale was modified by magmatic-related low-temperature hydrothermal fluid. Temperature measurements of brine inclusions and a semi-empirical geothermometer of chlorite show that low-temperature hydrothermal fluid experienced the chlorite stage (150–180 °C), the low-sulfidation stage (120–150 °C), and the low-temperature calcitization stage. Paleozoic fault systems and late Permian hydrothermal activities associated with the Emeishan mantle plume control the graphitization of low-resistivity shale. The water formation and seawater infiltrated into the deep crust along the Paleozoic basement faults under gravity, developing alkaline hot brine through mantle plume heating and then causing a water-rock reaction with basement rocks. They migrated upward along deep and large Paleozoic faults through convective thermal circulation in the Tiangongtang area, the Shuanglong-Luochang area, and the Xuyong area. Cation exchange and redox reactions occurred during the interaction between high-temperature hydrothermal fluid and cool wall rocks. The migration of alkaline hot brine via the Wufeng-Longmaxi shale introduced a subsequent water-rock reaction, resulting in the development of hydrothermal mineral assemblages that intricately filled fractures. It increased formation temperature and enhanced thermal maturity and graphitization of organic matter at the Wufeng-Longmaxi low-resistivity shale, resulting in a wide distribution of low-resistivity shale at the Changning Block.

Published: May 2023

The saturable absorber of niobium diselenide (NbSe2), with a wide working bandwidth and excellent nonlinear optical response, was prepared using liquid-phase exfoliation. Its saturation intensity and modulation depth were 5.35 MW/cm2 and 6.3%, respectively. Stable mode-locking with a center wavelength of 1558.7 nm of an erbium-doped fiber laser based on a NbSe2 saturable absorber was successfully achieved. The maximum average output power of the mode-locked laser was 6.93 mW, with a pulse width of 1.3 ps and a repetition rate of 25.31 MHz at a pump power of 550 mW. The results show that NbSe2 is a promising photoelectric modulation material owing to its excellent nonlinear optical properties.
Fluctuations-Induced Quantum Radiation and Reaction from an Atom in a Squeezed Quantum Field
Authors: Bravo Matthew , Hsiang Jen-Tsung , Hu Bei-Lok
Published: May 2023

In this third of a series on quantum radiation, we further explore the feasibility of using the memories (non-Markovianity) kept in a quantum field to decipher certain information about the early universe. As a model study, we let a massless quantum field be subjected to a parametric process for a finite time interval such that the mode frequency of the field transits from one constant value to another. This configuration thus mimics a statically-bounded universe, where there is an ‘in’ and an ‘out’ state with the scale factor approaching constants, not a continuously evolving one. The field subjected to squeezing by this process should contain some information of the process itself. If an atom is coupled to the field after the parametric process, its response will depend on the squeezing, and any quantum radiation emitted by the atom will carry this information away so that an observer at a much later time may still identify it. Our analyses show that (1) a remote observer cannot measure the generated squeezing via the radiation energy flux from the atom because the net radiation energy flux is canceled due to the correlation between the radiation field from the atom and the free field at the observer’s location. However, (2) there is a chance to identify squeezing by measuring the constant radiation energy density at late times. The only restriction is that this energy density is of the near-field nature and only an observer close to the atom can use it to unravel the information of squeezing. The second part of this paper focuses on (3) the dependence of squeezing on the functional form of the parametric process. By explicitly working out several examples, we demonstrate that the behavior of squeezing does reflect essential properties of the parametric process. Actually, striking features may show up in more complicated processes involving various scales. These analyses allow us to establish the connection between properties of a squeezed quantum field and details of the parametric process which performs the squeezing. Therefore, (4) one can construct templates to reconstitute the unknown parametric processes from the data of measurable quantities subjected to squeezing. In a sequel paper these results will be applied to a study of quantum radiations in cosmology.
Optimal Scheduling for Hybrid Battery Swapping System of Electric Vehicles
Authors: Wang Ziqi , Hou Sizu
Published: May 2023

Range anxiety seriously restricts the development of electric vehicles (EVs). To address the above issue, a hybrid battery swapping system (HBSS) is developed in this paper. In the system, EVs can swap their battery at battery swapping stations or by the roadside via battery swapping vans. The proposed scheduling strategy aims to achieve the best service quality for the HBSS by controlling the mobile swapping service fee. In the model, the uncertainty of EV selection is managed by leveraging the Sigmoid function. Based on proving the uniqueness of the solution, the particle swarm optimization algorithm is used to solve the problem. Simulations validate the effectiveness of the proposed strategy in alleviating range anxiety. Moreover, the impacts of maximum service capacity and the operating rule have been analyzed.

The ingestion of foreign bodies is a common cause for presentation in the emergency department by pediatric, adult, or elderly psychiatric patients. Swallowed foreign bodies sometimes represent a great challenge for surgeons due to the obstruction or perforation of the digestive tube’s upper or lower segments. Occasionally, the foreign bodies detected in the lower parts of the digestive tube (colon and rectum) could be introduced through the anal route with the risk of perforation of the rectum or sigmoid colon. In this report, we describe a unique case of a foreign body located in the sigmoid colon, where it arrived due to backstabbing and was retained for 7 years without acute symptoms. The 43-year-old male patient came to the emergency department with pain in the left iliac fossa. Before his presentation, a computerized tomography (CT) scan examination had suggested a foreign body. A surgical approach was decided. The surgery started as an exploratory laparoscopy and was converted to a xiphoid-pubic incision to extract the foreign body (a piece of glass about 8 cm long) through a sigmoid colotomy followed by a double-layer sigmoidorrhaphy. The postoperative evolution of the patient was uneventful. As far as we know, this is the first case of a patient with a foreign glass body positioned in the sigmoid colon that got there by stabbing and not by ingestion or introduced per anum. In conclusion, we suggest that aggressive behavior and abdominal wall penetration by different sharp objects should be considered when foreign bodies are detected in the abdomen.
Numerical Analysis of Highly Sensitive Twin-Core, Gold-Coated, D-Shaped Photonic Crystal Fiber Based on Surface Plasmon Resonance Sensor
Authors: Sardar Md. Ranju , Faisal Mohammad
Published: May 2023

This research article proposes and numerically investigates a photonic crystal fiber (PCF) based on a surface plasmon resonance (SPR) sensor for the detecting refractive index (RI) of unknown analytes. The plasmonic material (gold) layer is placed outside of the PCF by removing two air holes from the main structure, and a D-shaped PCF-SPR sensor is formed. The purpose of using a plasmonic material (gold) layer in a PCF structure is to introduce an SPR phenomenon. The structure of the PCF is likely enclosed by the analyte to be detected, and an external sensing system is used to measure changes in the SPR signal. Moreover, a perfectly matched layer (PML) is also placed outside of the PCF to absorb unwanted light signals towards the surface. The numerical investigation of all guiding properties of the PCF-SPR sensor is completed using a fully vectorial-based finite element method (FEM) to achieve the finest sensing performance. The design of the PCF-SPR sensor is completed using COMSOL Multiphysics software, version 1.4.50. According to the simulation results, the proposed PCF-SPR sensor has a maximum wavelength sensitivity of 9000 nm/RIU, an amplitude sensitivity of 3746 RIU−1, a sensor resolution of 1 × 10−5 RIU, and a figure of merit (FOM) of 900 RIU−1 in the x-polarized direction light signal. The miniaturized structure and high sensitivity of the proposed PCF-SPR sensor make it a promising candidate for detecting RI of analytes ranging from 1.28 to 1.42.
Generating Natural Cities Using 3D Road Network to Explore Living Structure: A Case Study in Hong Kong
Authors: Xiao Zhiyang , Peng Zhenhan , Yu Zidong , Liu Xintao
Published: May 2023

Compared with administrative cities, natural cities can be generally referred to as the areas generated based on the density of different urban facilities (e.g., point of interest, road network, etc.). To some extent, natural cities are outperformed in some related urban studies, such as urban living structure analysis. Nevertheless, traditional ways of generating natural cities are mostly limited to the planar space. Modern cities such as Hong Kong are vertical cities with high buildings, 3D road networks and land uses. Therefore, traditional nature cities could be biased when applied to 3D cities. In this work, a 3D road network in Hong Kong is adopted to extract true road intersections and generate modified natural cities to explore urban living structures. Numerous living structure units are classified into two parts: tiny and serried ones representing natural cities and vast ones representing rural areas. The classification method applies head/tail breaks, and a clustering algorithm was fitted for heavy-tailed distribution. According to the living structure theory, the living structures of the proposed natural cities and traditional natural cities based on the same road network in Hong Kong are compared. The findings show that the distribution of modified natural city regions is more reasonable compared with typical ones. The improved model will more clearly show the inherent living structure of the city and will allow an analysis of the relationship between the part and wholeness of the city.
Area under the Curve as an Alternative to Latent Growth Curve Modeling When Assessing the Effects of Predictor Variables on Repeated Measures of a Continuous Dependent Variable
Authors: Rodriguez Daniel
Published: May 2023

Researchers conducting longitudinal data analysis in psychology and the behavioral sciences have several statistical methods to choose from, most of which either require specialized software to conduct or advanced knowledge of statistical methods to inform the selection of the correct model options (e.g., correlation structure). One simple alternative to conventional longitudinal data analysis methods is to calculate the area under the curve (AUC) from repeated measures and then use this new variable in one’s model. The present study assessed the relative efficacy of two AUC measures: the AUC with respect to the ground (AUC-g) and the AUC with respect to the increase (AUC-i) in comparison to latent growth curve modeling (LGCM), a popular repeated measures data analysis method. Using data from the ongoing Panel Study of Income Dynamics (PSID), we assessed the effects of four predictor variables on repeated measures of social anxiety, using both the AUC and LGCM. We used the full information maximum likelihood (FIML) method to account for missing data in LGCM and multiple imputation to account for missing data in the calculation of both AUC measures. Extracting parameter estimates from these models, we next conducted Monte Carlo simulations to assess the parameter bias and power (two estimates of performance) of both methods in the same models, with sample sizes ranging from 741 to 50. The results using both AUC measures in the initial models paralleled those of LGCM, particularly with respect to the LGCM baseline. With respect to the simulations, both AUC measures preformed as well or even better than LGCM in all sample sizes assessed. These results suggest that the AUC may be a viable alternative to LGCM, especially for researchers with less access to the specialized software necessary to conduct LGCM.

Published: May 2023

Antimicrobial resistance (AMR) is increasing and represents one of the greatest public health challenges of our time, accounting for considerable morbidity and mortality globally. A “One Health” surveillance strategy, which integrates data concerning the resistant organisms circulating in humans, animals, and the environment, is required to monitor this issue and enable effective interventions. The timely collection, processing, analysis, and reporting of AMR surveillance data are necessary for the effective delivery of the information generated from such surveillance. Nepal has greatly improved its surveillance activities through a network of human and animal health laboratories; however, the data reported by sentinel laboratories are often inconsistent, incomplete, and delayed, causing challenges in terms of data cleaning, standardization, and visualization on a national level. To overcome these issues, innovative methods and procedures have been adopted in Nepal, with the development and customization of digital tools that reduce the human time and effort spent on data cleaning and standardization, with concomitant improvements in the accuracy of data. These standardized data can be uploaded to the district health information system 2 (DHIS2) One Health AMR surveillance portal, enabling the generation of reports that will help decision-makers and policy planners to combat the global problem of AMR.

Published: May 2023

The permeability of the natural geology plays a crucial role in accurately analyzing seepage behavior in the project area. This study presents a novel approach for the inverse analysis of the permeability coefficient. The finite element model (FEM) combined with orthogonal experimental design is used to construct a sample set of permeability coefficient inversion. The established random forest (RF) algorithm surrogate model is applied to determine the optimal values of permeability parameters in the project area using the Harris hawk optimization (HHO) algorithm. This method was used to explore and verify the distribution of natural seepage fields for the P hydropower station. The results showed that the RF model outperformed the classical CART and BP models at each borehole regarding performance evaluation indices. Furthermore, the water head prediction results were more accurate, and the RF model performed admirably in terms of prediction, anti-interference, and generalization. The HHO algorithm effectively searched for the optimal permeability coefficient of the geology. The maximum value of the relative error of the borehole water head inverted was 1.11%, and the accuracy met engineering standards. The initial seepage field distribution pattern calculated followed the basic distribution pattern of the mountain seepage field.

Knowledge is one of the valuable assets owned by an organization or an enterprise. But unfortunately, not all organizations have this awareness. The Laboratory Unit of the Faculty of Applied Sciences (FIT) is a unit that was established with the aim of managing laboratories and all practicum activities within the Faculty of Applied Sciences, Telkom University. Since its establishment until now, the FIT Laboratory Unit has undergone several staff changes. This happened due to the rotation or shift from the FIT Laboratory Unit to other units or due to the expiration of the contract period. In addition, because those chosen to be laboratory assistants are final year students of the Faculty of Applied Sciences, laboratory assistants also experience changes every year. Without good knowledge management, it will cause a loss for the organization. Because the knowledge gained by the staff, while working in the Laboratory Unit will also be lost when the staff moves. To overcome this problem, the researcher proposed a knowledge management system design that can assist organizations in managing and storing their knowledge be it tacit or explicit knowledge. It Also can make it easier for staff to share and transfer knowledge. In this research process, 10 Step Knowledge Management Roadmap by Amrit Tiwana is used as guidance. However, of the ten steps, this research is limited to the sixth step, which is the designing of a knowledge management system blueprint. From the analysis of the strategic approach of KM, it is found that the codification approach has a larger portion of application than the personalization approach. Furthermore, the design process is based on seven layers of KMS. To produce a knowledge management blueprint that can be applied in the development of KMS in the FIT Laboratory Unit.

Citato, mosaïque de la presse écrite
Authors: Simon Justine
Published: May 2023

Justine Simon montre que les jeunes lecteurs, non seulement lisent les journaux et font leur éducation citoyenne, mais se donnent aussi les instruments qui leur permettent de réfléchir à l’information qui leur est donnée. L’éclatement dans la présentation d’opinions sensiblement distinctes est un moyen de faire entrer les jeunes dans l’hétérogénéité discursive et argumentative des discours médiatiques.
Entretien entre Colombe Schneck et Serge Guérin
Authors: Schneck Colombe , Guérin Serge
Published: May 2023

Colombe Schneck assume aujourd’hui l’animation de deux émissions phares traitant des médias : i-médias sur i-télé et J’ai mes Sources à France Inter. Sur ce créneau, elle a su devenir incontournable et inventer son propre style de prise de parole en évitant les discours trop convenus. Ses émissions ne sont ni une copie du travail de Daniel Schneidermann, ni un lieu seulement dédié à la promotion d’un petit monde autocentré sur son actualité. Il est intéressant que cette journaliste spécialisée sur les médias puisse développer une vision «enchantée » des médias.

La reconnaissance des écoles de journalisme
Authors: Papet Jacqueline
Published: May 2023

La formation journalistique en France fait l’objet d’un débat plus intense que jamais, ce dont témoigne ce numéro de MédiaMorphoses. Parmi les acteurs institutionnels de la formation, la CNPEJ, commission nationale paritaire de l’emploi des journalistes, occupe une place de choix. C’est elle qui attribue la reconnaissance par la profession aux écoles de journalisme. Jacqueline Papet, membre de cette commission, nous présente le fonctionnement de cette institution, à l’heure où celle-ci connaît de nouvelles évolutions avec la redéfinition de dix nouveaux critères de reconnaissance.
Journalisme et web : quels outils de formation?

Published: May 2023

Florence le Cam et Olivier Tredan ont enquêté auprès de plusieurs écoles de journalisme pour comprendre comment un nouveau support et de nouvelles écritures pouvaient être investies dans les cadres d’une formation. Où l’on constate que les questions récurrentes à la formation des journalistes réapparaissent : dosage entre compétences technologiques et rédactionnelles, appropriation d’un espace avec ses codes d’écriture particuliers, travail sur les modes de la réception…
Reflective practices for veterinary nurses
Authors:   , Clare Morton
Published: May 2023

Reflective practice is a skill that is currently underutilised in the veterinary industry. Teaching reflectiveness to our veterinary nurses and educators is part of looking at how we can improve mental wellbeing and create sustainability in our industry. Reflective models from Schon (1983) and Gibbs (1998) were adapted and utilised depending on where and how the reflecting was undertaken. I surveyed educators and veterinary nurses about their views on reflective practices and how they were used in the classroom and vet clinics. Additionally, how they practiced reflectiveness personally and within their work teams. I employed surveys and questionnaires as part of a grounded theory approach (Glaser & Strauss, 1967). My findings showed a wide range of understanding of reflectiveness and how it can be used. It also indicated that our educators range from those who practice reflectiveness to those who are unsure of what it means. We need to teach our educators this skill before introducing it to our students. Educators who become familiar with reflectiveness can teach this to students using adapted reflective models and, by using journals or diaries, can guide them through the steps of reflection. By teaching our students reflective practices, graduates can take these techniques into the industry and use them effectively to overcome stress and compassion fatigue. The conclusions from my research have shown that there are two different types of reflective practice. Firstly, we seek to teach our students reflective writing to an academic level and aim to see a learning progression throughout their studies. Secondly, reflective practices in the veterinary industry promote a sustainable work/life balance and may include such activities as exercise, arts, and contact with family and friends. Recommendations include using reflective models designed for our students and using reflective journals as a formative task allowing feedback to be provided in preparation for summative assessments. Finally, to use reflective practices within our vet nursing school to enable educators to become comfortable teaching this to our learners so they can take this learning out into veterinary practice.
Challenges of the digital culture in education in the family
Authors: Šehić Damir
Published: May 2023

The effects of digital culture have transformed society and human ethos, and exponential digitalization has led to an anthropological transformation. By causing profound and complex changes in all levels of the sociocultural environment, digital culture has also changed the psychological, physiological, spiritual, and moral consequences of an individual and family in general. The challenges that digital culture poses to family life by modifying relations of spouses, are also reflected in the upbringing of children and their education, reshaping language, changing mentality, and restructuring value hierarchies. This paper approaches the topic through two thematic units, the first of which aims to detect some of the most serious challenges of digital culture confronting education in the family. The second part discusses the phenomenon of the “technological disconnect” of family members and some aspects of the challenges that this new phenomenon poses to education in the family. This part of the paper discusses the “technological disconnect” of parents and its implications on children and their moral education, observing the problems of shifting responsibility for upbringing and education to the technology and media, as well as the phenomenon of parental alienation syndrome. While not disregarding all the benefits of the postmodern digital culture, this work aims at emphasizing and contributing to the discussion on the negative implications of “technological disconnect” on the moral aspect of education in the family.
Using Material Flow and Stock Indicators to Evaluate Urban Allometry: Evidence from the Beijing–Tianjin–Hebei Region

The growing urban population is intensifying global resource shortages. It is essential for scholars and policymakers to better understand the material-based metabolism of cities for sustainable urban resource management. Taking the Beijing–Tianjin–Hebei region of China as a representative case, this study quantifies domestic material consumption (DMC) and material stock (MS) and reveals the dynamics of the material-based urban metabolism of cities during 2000 to 2017 based on the allometric scaling law. The results show that the DMC and MS of each city exhibited an overall increasing trend during 2000 to 2017, with Beijing, Tianjin, Shijiazhuang, Baoding, Handan, and Tangshan having larger material bases than the other cities. Cities at different stages of development usually follow different material-based allometric scaling law relationships. Most cities in this region (9 out of 13) follow a superlinear relationship, indicating excessive consumption of resources in these cities. The scaling coefficient of Beijing is most similar to the value (0.75) that has been observed in many types of biological research, which suggests that Beijing has reached a relative stabilization stage of development. This study provides key points for future resource allocation and industrial optimization related to urban material metabolism in the Beijing–Tianjin–Hebei region. The findings of this study can enrich the theoretical and empirical bases for urban allometry research and provide urban managers with additional insights for consideration to achieve sustainable urban resource management.

Políticas públicas en Navarra sobre víctimas de la rebelión militar de 1936
Authors: Garmendia Amutxastegi Gotzon
Published: May 2023

El objetivo definido es analizar la evolución de las políticas públicas sobre memoria colectiva y la defensa de derechos humanos, implementadas en Navarra durante el pe­ríodo 1979-2019. Las fuentes utilizadas son: Diario de Sesiones parlamentarias; leyes, decretos y órdenes (BOE y BON); planes de gobierno, acciones de las asociaciones sociales; bibliografía y hemerografia. De este estudio se infiere que las políticas públicas estuvieron condicionadas por: 1) la estrategia de consolidación del «régimen del 78»; 2) las políticas de Estado dirigidas a la neutralización de las alternativas disidentes; y 3) la evolución de la correlación de fuerzas sociopolíticas producida durante los años 80 del pasado siglo.
Diálogo con la población castellanohablante navarra sobre el fomento de la lengua vasca
Authors: Erize Xabier
Published: May 2023

Navarra tiene dos lenguas propias: euskera (minoritaria) y castellano (mayoritaria). Existe escaso diálogo entre los agentes de las políticas de fomento del euskera y la parte castellanohablante de la población. Ello trae discusión social y limitaciones para el fomento. Es un problema poco estudiado. Objetivo: conocer los motivos (razones, sentimientos) de la ciudadanía castellanohablante respecto al fomento del euskera. Mé­todo: cualitativo-etnográfico. Resultados, motivos hallados: les gusta el mantenimiento del euskera como patrimonio cultural y que el fomento sea inclusivo, no ideologizado. Implicaciones: incorporar esos motivos enriquecería el fomento práctico y la investiga­ción.
