Flood frequency analysis – Part 2: Development of a modified plotting position
Authors: D van der Spuy  , JA du Plessis
Published: April 2022

The original plotting position concept was suggested more than a century ago. Since then, many alternative plotting position approaches have been developed. Despite a general lack of agreement around which plotting position is theoretically ‘correct’ and the ‘best’ to use, all plotting positions fail to adequately address outliers and data of similar magnitude. Hydrologists generally fail to acknowledge that the plotting position primarily offers an informative display of data, against which distributions can be compared, rather than an absolute measure of probability. This paper does not intend to challenge any of the many lengthy theoretical mathematical arguments, utilised to ‘prove’ why one plotting position is superior to the others. These theoretical arguments may very well be valid for a ‘population’ of flood peaks – the reality, however, is that hydrologists are confronted with the challenge of analysing very limited ‘samples’ of the population. Consequently, the plotting position issue demands a more pragmatic approach, rather than a purely theoretical approach. This paper illustrates various problems with existing plotting position techniques in use and offers an alternative approach and a more sensible plotting position technique, using Z-scores and referred to as the Z-set PP, against which distributions can be checked. The study further illustrates how effectively the Z‑set PP deals with outliers and its robustness with various record lengths. Although derived from a study of flood peak data obtained from South African flow-gauging sites, it is deemed that it will be universally applicable.

Published: April 2022

The adsorption of eight selected potentially toxic metal ions from actual mining wastewater obtained from Igbeti, Nigeria, was established using activated carbon chemically prepared from Carica papaya stem with zinc chloride (CPSAC-ZnCl2) as activating agent. Characterization of the prepared CPSAC-ZnCl2 sample for surface morphology and functional groups was done by scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy, respectively. An atomic absorption spectrophotometer (AAS) was utilized for characterization of the selected metals in the mining wastewater. Batch adsorption and desorption studies were conducted on removal of the metals from the sample using CPSAC-ZnCl2. The data obtained were fitted to isotherm (Freundlich and Langmuir); kinetic (pseudo-second-order and intra-particle diffusion) and thermodynamic (standard enthalpy change – ΔH°, entropy change – ΔS° and free energy change – ΔG°) models. These were considered under two error functions (sum of absolute errors – SAE,  coefficient of determination – R2) of linear and non-linear regression analyses. The SEM micrograph revealed that the CPSAC-ZnCl2 sample was 2.0–50.0 nm with FTIR spectra absorption peaks ranging from 746.2 to 3 987.0 cm-1. The initial concentrations of selected metals in the wastewater varied from 5.7 to 756.5 mg/L. The adsorbent dosage, agitation rate, contact time, pH and temperature for optimum condition of CPSAC-ZnCl2 were 0.6 g, 150.0 r/min, 60 min, pH of 7.0 and 30°C, respectively. The selected metals’ adsorption onto CPSAC-ZnCl2 followed Freundlich and Langmuir isotherm models pseudo-second-order kinetics with intra-particle diffusion mechanism. The ΔH°, ΔS° and ΔG° for the processes were 134.5, 64.5 and 22 012.0 kJ/mol, respectively. The adsorbent achieved an adsorption efficiency of above 95.0%, and is thus recommended for industrial application in remediating potentially toxic metals from wastewater.

Authors: Zakaria A Mohamed  , Saad Alamri  , Mohamed Hashem
Published: April 2022

The present study determines the endotoxin removal efficiency of drinking water treatment plants (DWTPs) in Egypt, as examples of conventional treatment methods used in developing countries. The total endotoxin in source water (Nile River) of these DWTPs ranged from 57 to 187 EU∙mL−1, depending on the location of treatment plants.  Coagulation/ flocculation/sedimentation (C/F/S) after chlorine pre-oxidation removed bound endotoxins by 76.1–85.5%, but caused cell lysis and increased free endotoxins by 28.2–33.3% of those detected in raw waters. Rapid sand filtration had not significant effect on free endotoxins, but reduced bound endotoxins by 23–33.3%. Final chlorine disinfection also reduced bound endotoxins to levels around 1 EU/mL, accompanied by an increase in free endotoxins (37–112 EU∙mL−1) in finished waters. Simultaneously, final chlorine disinfection removed all heterotrophic bacteria, with low cyanobacterial cell numbers (348–2 450 cells∙mL−1) detected in finished waters. Overall, conventional treatment processes at these DWTPs could removal substantial amounts of bound endotoxins and bacterial cells, but increase free endotoxins through cell lysis induced by pre-oxidation and final chlorine disinfection. The study suggests that conventional processes at DWTPs should be optimized and upgraded to improve their performance in endotoxin removal and ensure safe distribution of treated water to consumers.

Published: April 2022

Bu çalışmanın amacı günümüzün en popüler sosyal medya platformlarından biri olan Twitter’ın siyasal alanla ilişkisini siyasal partiler üzerinden ele alarak incelemektir. Bu amaçla çalışmada Türkiye Büyük Millet Meclisi’nde grubu bulunan 5 siyasal partinin Twitter hesapları incelenmiştir. Hesapların incelenmesinde nicel içerik analizi yöntemi kullanılmıştır. Partilere ait Twitter hesapları genel bilgiler, içerik paylaşım sayıları ile hesapların etkileşim oranları üzerinden analiz edilmiştir. Ayrıca paylaşılan içerikler siyasal iletişim türü, konusu ve formatları açısından da ayrıca analiz edilerek irdelenmiştir. Sonuçlar partilerin takipçi sayıları ile hesapların etkileşim oranlarının almış oldukları oy oranlarıyla doğrusal bir ilişkisi olmadığını göstermektedir. Partilere ait hesapların çoğunlukla liderlere ait diğer sosyal medya hesaplarını desteklemek ve duyurumda bulunmak için kullanıldığı tespit edilmiştir. Öte yandan, hesaplardan paylaşılan içeriklerin çoğunluğu videolardan oluşurken, yaratıcı ve özgün içerik sayısı oldukça azdır.

Published: April 2022

Monoclonal antibodies are pure antibodies that react to a specific epitope. Plasmapheresis is a treatment that separates and eliminates disease-causing substances before replacing the blood with plasma. Plasmapheresis has insufficient evidence for treating new-onset refractory status epilepticus (NORSE). Sequential plasmaphereses gradually improved a female cryptogenic NORSE patient who did not benefit from monoclonal antibody treatment.
A Diagnostic Dilemma: Normal Repetitive Nerve Stimulation in Lambert-Eaton Myasthenic Syndrome
Authors: Jeong Yu Hun , Seok Hung Youl
Published: April 2022

It is important for the diagnosis of Lambert-Eaton myasthenic syndrome (LEMS) to confirm the incremental response at high-rate stimulation or after brief exercise in the repetitive nerve stimulation (RNS) test. Therefore, it may be difficult to diagnose LEMS if the RNS test is normal initially. We report a patient with LEMS whose diagnosis was delayed due to normal RNS findings. We believe that anti-P/Q-type voltage-gated calcium channel antibody testing is crucial in the diagnosis of LEMS.

Published: April 2022

A 70-year-old female presented with progressive gait disturbance. Neurologic examination revealed sensory impairment, hyporeflexia, and sensory ataxia. Nerve conduction study demonstrated mildly decreased velocity in motor nerves. Brain magnetic resonance imaging showed high signal intensities in the corticomedullary junction on diffusion weighted imaging. Neurocognitive function test implied mild cognitive impairment. Based on eosinophilic intranuclear inclusions in pathology, neuronal intranuclear inclusion disease was confirmed. Neuronal intranuclear inclusion needs to be considered when abnormal nerve conduction studies are consistent with abnormal brain imaging findings.

Published: April 2022

The life cycle of Rafflesia is very complex because it involves the invisible and visible parts of its growth. The invisible part refers to its penetration, inoculation of the seeds into the host’s tissue and seed formation whereas the visible part is the floral structure that is exposed to the external environments. Currently, there is little information on the life cycle of Rafflesia, therefore knowledge regarding its life cycle is crucial for a successful monitoring of the species as part of conservation efforts. The objectives of this study were to analyse the growth of flower buds at various developmental stages and mortality rates of Rafflesia azlanii and R. cantleyi, and to observe the life cycle of the two species. The growth rate of R. azlanii and R. cantleyi were recorded monthly for five months beginning from an emergence of buds to full bloom in the study sites of Belum-Temenggor Forest Complex, Perak. The buds were measured and vertically photographed for every observation and categorized into eight stages. R. azlanii buds grew at the mean rate of 0.20 cm/day and R. cantleyiwas at 0.26 cm/day. This suggests that R. azlanii exhibited a slower growth rate than R. cantleyi. In addition, the mortality rate of R. azlanii (28%) was lower than R. cantleyi (45%). The high mortality rate could be due to two factors; an exposure of the plants to direct sunlight and damage caused by pests. Meanwhile, the life cycle for the visible stage for R. azlanii was 14 months and R. cantleyiwas 11 months. The information gathered from this study is useful for field monitoring and observation of the plants for conservation purposes.

Published: April 2022

Seagrass ecosystems can be mapped using RS because this technique is versatile and accurate. The availability of seagrass information is very important for the sustainable management of seagrass ecosystems. The use of RS technology to map seagrass has become the focus of many researches worldwide by using various types of platforms, sensors and various algorithms for satellite imagery processing. In literature, there have been many review papers related to seagrass, however, a comprehensive review on various aspects of seagrass is limited. The objective of this review paper was to fill the gap by highlighting the existing RS technology, seagrass biophysical property and image processing analysis. Review results indicated that RS technology is a powerful tool for accelerating seagrass mapping and for monitoring the condition of seagrass ecosystems at regional scale due to the availability of long-archived RS data and their free-access. In literature, the empirical approaches still dominated seagrass mapping methodology compared to the semi-analytic and analytic approaches. A clear conclusion from this review is that the development in sensor technology and data processing algorithm is still ongoing and has driven RS capabilities to map seagrass more rapidly, accurately and less expensive. Future research on seagrass mapping could be focused on a more automated classification by applying machine-learning to handle a large amount of data to improve accuracy and to discover robust methods for image pre-processing that is suitable for tropical shallow waters such as those in Indonesia.

Honey has been consumed since ancient time due to its nutritional and therapeutic values. Studies showed that honey possesses antioxidant properties which can inhibit oxidation and cell damage in the body. However, the chemical contents and antioxidant properties of honeys are varied, depending on botanical and geographical origins of honey. In this study, we analysed the total phenolic content (TPC), total flavonoid content (TFC), antioxidant properties (DPPH, ABTS, FRAP and TAOC) and volatile profiles of several commercial honeys originated from Malaysia, Turkey, and Yemen. The results showed that sample H4 (Pine honey) from Turkey was the highest in TPC (0.84 µg GAE/mg honey), ABTS (63.15% inhibition) and FRAP (0.45 µg FeSO4 equivalent/mg honey) values, while H2 (Acacia honey) from Malaysia showed the highest values in TFC (0.11 µg quercetin equivalent/mg honey) and DPPH (45.13 mg/mL IC50). Meanwhile, H5 (Marai honey) from Yemen recorded the highest TAOC value (24.14 µg ascorbic acid equivalent/mg honey). Twenty-four volatile compounds were identified using gas chromatography-mass spectrometry (GC-MS), among others are 4H-pyran-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl, linoleic acid ethyl ester, 2,5-dimethyl-4-hydroxy-3(2H)-furanone, and 2,4-dihydroxy-2,5-dimethyl-3(2H)-furan-3-one which contribute to chemical characteristics of certain honeys. In regards to the TPC, TFC, and antioxidant assays, the honey samples were ranked based on the chemical properties level as follows: H4 (Pine honey) > H2 (Acacia honey) > H7 (Kelulut 2) > H3 (Kelulut 1) > H6 (Sumar honey) > H1 (Tualang honey) > H5 (Marai honey). This finding increases the knowledge of the chemical compositions, volatile compounds, and antioxidant activities of several commercial honeys derived from different botanical and geographical origins.
Dehydroabietic Acid Attenuates Atherosclerosis in Apolipoprotein E-Deficient Mice and VCAM-1 Expressions in-vitro
Authors: Xiao Liang , Yan Wu
Published: April 2022

Dehydroabietic acid (DHA) is an analog of abietic acid (AA) for cardiovascular disease prevention, known to act pharmacologically against aging, inflammation, bacterial infections and cancer. The current research investigated the molecular mechanisms of DHA on the adhesiveness of endothelial leukocytes and activation of NF-κB in TNF-α treated HAEC and ApoE−/− mice in experimental atherosclerosis. The HAECs were tested for toxicity using MTT assay at various DHA concentrations. The cell-surface expression of CAM against endothelial leukocyte adhesion molecule-1, ICAM -1, or human VCAM-1 was determined by the ELISA test, followed by western blot analysis. Endothelial cell-leukocyte adhesion assay involving U937 cells was carried out followed by the determination of NF-κB p65 expression. ApoE−/− mice were fed with a high cholesterol diet every day followed by oral administration of DHA (10 and 20 mg/kg/day). The DHA (5 and 10 mM) substantially reduced (p < 0.05) human (U937) cell lines binding to TNF-α activated human endothelial aortic cells. The assays involving the 32P-labelled NF-kB as a probe demonstrated that DHA pre-treatment decreased the shifted bands density following the stimulation of TNF-α. Nuclear extracts immune blot assessment and immune fluorescence staining showed a significant decrease (p < 0.05) in the NF-κB p65 concentration in the nuclei with DHA treated human endothelial aortic cells. Together these findings indicate that DHA inhibits nuclear trans localization of TNF-α-induced NF-κB p65, and thus considerably suppresses (p < 0.05) the VCAM-1 expression, which contributes to lower leukocyte adherence suggesting that DHA helps in preventing inflammatory atherosclerosis in vivo.

Published: April 2022

The production of oil sludge per year is more than 1 billion tonne that mainly generated from the production, refinery, storage, and transportation of petroleum. Disposal of oil sludge had been a great issue since the waste consists of highly concentrated of Natural Occurring Radioactive Material (NORM). Therefore, to overcome this problem, this study aims to investigate used and recycle borosilicate glass as a host for solidification of oil sludge. The oil sludge and glass host were mixed into different compositions, melted at high temperature (1,100 °C -1,200 °C) for 1 h in alumina crucible and rapidly cooling in the room temperature, by reducing the radioactivity levels of NORM. This study found out that, the optimum waste loading was obtained at a range of 20-25 wt% of oil sludge and 75-80 wt% of the glass host at 1,200 °C. All the glass waste was produced as an amorphous phase material with small amount of crystalline phase such as SiO2, Ba4-Al2-O7, AlPO4, Al2O3 and Fe3Zn10, which observed to be appeared during the cooling process. The major elements of the glass waste were found to be distributed uniformly based on energy dispersive X-ray spectroscopy (EDX) mapping. Furthermore, the dissolution rate of indicator element increased due to the increase of pH solution, while the normalized releases of B, Si, and Na during product consistency tests were low and below the standard glass limit, which shows high durability of the glass due to lower release of glass elements. Therefore, this study emphasized the suitability of recycle borosilicate glass as a host for immobilization of oil sludge prior for disposal, while deploying high temperature technology.

Published: April 2022

The Moreton wave has been extensively studied in explaining the relation between solar flare, Coronal Mass Ejections (CMEs) and Solar Radio Solar Burst Type II (SRBT II) phenomena. The purpose of this study was to determine whether Moreton waves have an impact on CME structure based on SRBT II parameters. The drift rate and structures of 28 SRBT II events selected from year 2014 to 2017 and observed by using ground-based Compound Low-cost Low Frequency Transportable Observatory (CALLISTO) spectrometer were determined. The CME data such as width angle and velocity were obtained from Large Angle Spectroscopy Coronagraph Observatory (LASCO) instrument, while solar flare class and its Active Region (AR) were attained from the Geostationary Operational Environmental Satellite (GOES). From the results, impulsive CME events have X, M and C class of solar flare in the presence of Moreton wave by using GONG data archive while gradual CME were associated with C or B class of solar flare. Impulsive CMEs have an angle of width more than 60° and velocity more than 500 km/s associated with both herringbone (HB) and harmonic structure of SRBT II. However, 30% of gradual CMEs which are associated with HB structure of SRBT II did not accompany by Moreton wave presence. Therefore, we can deduce that the impulsive CMEs are formed under the influence of Moreton wave and gradual CMEs emerged without the Moreton wave, based on the structure of SRBT II.
Entanglements of Identity and Resilience in the Camp Fire’s Network of Disaster-Specific Facebook Groups
Authors: Benedict Bailey C.
Published: April 2022

The Camp Fire in California (November 2018) was one of the most destructive wildfires in recorded history. Dozens of Facebook groups emerged to help people impacted by the Camp Fire. Its variety and prevalence throughout recovery make this network of disaster-specific, recovery-oriented social media groups a distinct context for inquiry. Reflexive thematic analysis was performed on 25 interviews with group administrators and publicly available descriptive data from 92 Facebook groups to characterize the composition of the network and explore identity in the groups. Group members’ identities fell into two categories—helpers and survivors—while the groups consisted of six identities: general, specialized, survivor-only, pet-related, location-specific, and adoptive. Administrators established group identity around purpose, through membership criteria, and in similarity and opposition to other Camp Fire Facebook groups. The findings contribute to social identity theory and the communication theory of resilience at the intersection of resilience labor, identity anchors, and communication networks.
Expertise, Knowledge, and Resilience in #AcademicTwitter: Enacting Resilience-Craft in a Community of Practice
Authors: Eddington Sean M. , Jarvis Caitlyn
Published: April 2022

Online communities of practice are a useful professional development space, where members can exchange information, aggregate expertise, and find support. These communities have grown in popularity within higher education—especially on social networking sites like Twitter. Although popular within academe, less is known about how specific online communities of practice respond and adapt during times of crisis (e.g., building capacity for resilience). We examined 22,078 tweets from #AcademicTwitter during the first two months of the Covid-19 pandemic, which impacted higher education institutions greatly, to explore how #AcademicTwitter enacted resilience during this time. Using text mining and semantic network analysis, we highlight three specific communicative processes that constitute resilience through a form of resilience labor that we conceptualize as “resilience craft.” Our findings provide theoretical significance by showing how resilience craft can extend theorizing around both communities of practice and the communicative theory of resilience through a new form of resilience labor. We offer pragmatic implications given our findings that address how universities and colleges can act resiliently in the face of uncertainty.

The Use of Pre-Trial Expert Investigations in Civil Cases
Authors: Zubovich M. M. , Korshakova K. V. , Tombulova E. G.
Published: April 2022

The authors attempt to analyze the use of pre-trial expert investigation through the prism of the norms of current legislation and law enforcement practice. Having studied the approaches available in judicial practice, the authors come to the reasoned conclusion that the results of pre-trial expert investigations (acts of expertise) submitted by the parties to the court in civil cases are given evidentiary value. At the same time, courts should take into account the evidentiary value of pre-trial investigations and decide in favour of conducting forensic examinations only if there is insufficient clarity or incompleteness of pre-trial expert investigation or in connection with doubts about the correctness or validity of the results of pre-trial investigations. Pre-trial psychophysiological investigations using a polygraph are not subject to this algorithm that can also have evidentiary value in a civil case (the article provides an example of such a procedural situation). However, they cannot currently use the appointment of a forensic psychophysiological examination using a polygraph as the second stage due to the lack of a uniform scientifically grounded methodology for conducting such a judicial examination. Meanwhile, as the authors believe, creation of such a scientifically based methodology for conducting a forensic psychophysiological examination is a matter of the nearest future. This is supported by the actively accumulated experience of using a polygraph in different countries (in particular, in the Republic of Lithuania). In view of the prospect of using a polygraph in the near future, the authors give examples of private law situations in which the use of a polygraph in civil cases could become expedient and help courts in making informed decisions.

Authors: Vereshchagina A. V. , Kumankova D. A.
Published: April 2022

Judicial control is understood as control over the compliance of the activities and decisions of lawenforcement agencies and officials with the requirements established by law. The legal procedure for exercisingjudicial control in the Russian Federation has been criticized. Since 2015, Russia has seen intensification of a discussionabout the establishment of a special subject, namely an investigating judge who would exercise judicial controlover pre-trial proceedings. Some states have experience in exercising judicial control over pre-trial proceedings byinvestigating judges. One of these states is the Republic of Moldova. The paper presents the results of the studyof the regulatory model of the institution of judicial control over pre-trial proceedings in the Republic of Moldova.The purpose of the work is to study the evolution of the institution of judicial control in the Republic of Moldova. Toachieve the formulated goal, it is necessary to solve the following tasks: 1) to determine the concept and appointmentof a judge for criminal prosecution; 2) to highlight the stages of development of judicial control over pre-trialproceedings in Moldova; 3) to designate the range of basic powers of a judge in criminal prosecution. Historicaldiachronic, logical-dogmatic and comparative-legal methods are used in the research. An analysis of the regulatoryprovisions concerning the implementation of judicial control over pre-trial proceedings allows us to conclude thatit is sufficiently elaborated in the criminal procedure legislation of the Republic of Moldova. The advantages of theinstitution under study are: the establishment of a special entity exercising judicial control over pre-trial proceedings;systemic regulation of his powers; lack of duplication of norms; consistent adjustment of the institution.

A reunificação familiar é um processo complexo que se inicia com o acolhimento residencial da criança e/ou jovem na instituição e continua após o regresso a casa, podendo contribuir para consolidação e sucesso das medidas de proteção. O presente estudo teve como objetivo analisar as dinâmicas geradoras dos processos de resiliência em famílias após implementação do Programa “Caminhar em Família”  que visa a reunificação familiar por meio de promoção de competências parentais durante o acolhimento. Foi desenvolvido um estudo de caso qualitativo de caráter descritivo e retrospectivo. A amostra não probabilística foi composta por 4 famílias, sendo 5 progenitores e 6 crianças/jovens que saíram do acolhimento no ano de 2019  e estavam aptas à reunificação. A participação das famílias no programa permitiu confirmar o fortalecimento da resiliência no sistema relacional de pais e filhos graças à compreensão, capacitação e empoderamento suscitados nas diferentes etapas da medida de proteção. A associação conceitual de dois modelos teóricos da resiliência familiar das autoras  Froma Walsh e Lietz e Strenght  possibilitou identificar diferentes forças e recursos individuais e familiares na gestão da crise e respostas específicas às necessidades das famílias nos diferentes estádios do acolhimento e reunificação. Os resultados reforçam a importância de programas socioeducativos que privilegiam o fortalecimento das dimensões promotoras de aspectos saudáveis que compõe a resiliência em famílias.  Estes elementos devem ser os norteadores das intervenções para uma reunificação familiar segura e estável.
Inteligência emocional e gestão de conflito na interação pedagógica
Authors: Valente Sabina , Lourenço Abílio
Published: April 2022

Vários estudos mostram a relação entre as capacidades da inteligência emocional e a gestão de conflito nas relações pessoais. No entanto, são escassos os que investigam estes constructos na interação professor-aluno. Para colmatar esta lacuna, este estudo teve por objetivo investigar como as capacidades da inteligência emocional do professor influenciam as estratégias usadas para gerir o conflito na aula. Entende-se por estratégias de gestão de conflito os tipos de comportamentos que se adotam para gerir o conflito. A amostra incluiu 431 professores, de escolas públicas portuguesas. Foram aplicados o Questionário de Inteligência Emocional do Professor, e o Rahim Organizational Conflict Inventory II - Portuguese Version in School Context. Usando a técnica de modelação de equações estruturais, os resultados mostraram que os professores que tendem a pontuar mais alto nas capacidades emocionais da inteligência emocional usam mais estratégias de integração e de compromisso para gerir o conflito. Os resultados sugerem que as capacidades emocionais do professor são promotoras do uso de estratégias mais adequadas à gestão de conflitos, em contexto de aula. Em conclusão, o desenvolvimento das capacidades de inteligência emocional dos professores é uma prioridade, dado o seu papel interativo antes e durante o conflito. Neste sentido, defende-se um modelo educativo que dê prioridade às capacidades emocionais na formação inicial de professores, e que promova programas de intervenção que desenvolvam essas capacidades nos professores em serviço, como recurso primordial à gestão de conflitos na relação pedagógica.

Authors: Iglesias-Caride Gabriel , Domínguez-Alonso José , González-Rodríguez Rubén
Published: April 2022

El presente estudio pretende conocer si la ubicación del centro educativo al que acuden los adolescentes determina el uso de videojuegos de esta población. Este trabajo se integra dentro de una investigación de carácter cuantitativo de tipo descriptivo, que cuenta con una muestra total de 708 adolescentes cursando o bien educación secundaria o bachillerato en el momento de la recolección de datos, con edades comprendidas entre los 12 y los 18 años (M: 13.81; DT: 1.25). Se utilizó un cuestionario con ítems de variables personales, académicas y uso de videojuegos. Los resultados obtenidos muestran que aquellos jóvenes que acuden a un centro urbano refieren que los videojuegos son la principal ocupación de su tiempo libre en mayor medida que los que acuden a centros rurales. El primer colectivo refiere tanto más años dedicados como más horas invertidas a este tipo de divertimento, especialmente durante la semana lectiva. En lo referente a la plataforma preferida de juego, emergen preferencias similares, ocupando el primer lugar el móvil o Tablet y la consola conectada a televisión. Finalmente, los jóvenes rurales prefieren hacer uso del videojuego Among Us, mientras que los urbanos, Fortnite, mostrando ambos grupos gran preferencia por juegos online multijugador. A modo de conclusión, es interesante contrastar datos sobre uso de videojuegos en población rural y urbana para conocer cómo se interrelacionan dos realidades actuales: por un lado, la expansión paulatina del mundo de videojuego, y, por el otro, la realidad de la brecha digital entre los ámbitos urbano y rural.
Autoconcepto del alumnado universitario
Authors: Vázquez Clara , Risso Alicia
Published: April 2022

El objetivo del estudio era conocer la relación entre el autoconcepto del alumnado universitario y variables académicas y personales, para identificar sus características en distintos grupos y, en futuras investigaciones, usar los resultados en la creación de intervenciones para facilitar su transición al sector profesional. Participaron voluntariamente estudiantes de ambos sexos, distintas edades, cursos y ramas de conocimiento de la Universidad de A Coruña (N = 512). El instrumento utilizado fue una escala auto-administrada de elaboración propia, con 38 pares de adjetivos bipolares, tipo diferencial semántico, pero con únicamente los polos positivos y negativos. Un AFE, realizado en un estudio previo con una muestra clínica, reveló la existencia de cinco factores (Bienestar Hedónico, Autoconcepto Ético, Ocupacional, Habilidades de Comunicación y Ajuste Emocional), posteriormente confirmados mediante un AFC realizado con la muestra del presente estudio. Los resultados mostraron correlaciones significativas del sexo con el Autoconcepto Ocupacional y las Habilidades de Comunicación, y del nivel educativo con el Autoconcepto Ocupacional y con el Ético. Además, los análisis revelaron puntuaciones significativamente mayores en Autoconcepto Ocupacional y en Habilidades de Comunicación en varones, mientras que el mayor Autoconcepto Ocupacional se encontró en alumnado de la rama de Ingeniería y Arquitectura. También se encontraron puntuaciones superiores en el autoconcepto Ocupacional y Ético en el alumnado de Grado. Estos hallazgos permiten identificar áreas de autoconcepto útiles en el desarrollo de estrategias que faciliten la búsqueda de empleo y la inserción profesional de la población universitaria, así como la mejora, en definitiva, de su calidad de vida.
Personalidade, resiliência e bem-estar subjetivo de alunos do ensino superior
Authors: Francisco Marisa , Félix Débora , Armando Ferreira Joaquim
Published: April 2022

Este estudo tem como objetivo investigar as relações entre a personalidade, a resiliência e o bem-estar subjetivo de alunos do ensino superior, testando o valor preditivo que a resiliência possa acrescentar às dimensões da personalidade. A amostra é constituída por 197 participantes, com idades compreendidas entre os 18 e os 29 anos, de ambos os sexos. Para avaliar as variáveis em estudo foram aplicados o Big Five Inventory (BFI), a Escala de Satisfação com a Vida (SWLS), a Escala de Afetividade Positiva e Afetividade Negativa (PANAS) – versão reduzida, e a Escala Abreviada de Resiliência (BRS). Os resultados foram comparados em função do sexo e saída de casa dos pais, não se verificando, no entanto, diferenças estatisticamente significativas em nenhum dos dois. Foram encontradas correlações estatisticamente significativas entre afetividade negativa e neuroticismo. A resiliência correlacionou-se com a extroversão. Satisfação com a vida apresentou correlações significativas com amabilidade, conscienciosidade e resiliência. E ainda, a afetividade positiva apresentou correlação significativa com a resiliência, com a satisfação com a vida e com todas as dimensões da personalidade, menos com o neuroticismo. Os resultados indicam que, efetivamente, a personalidade é um forte preditor de bem-estar, e que a capacidade de resiliência apresenta relações positivas significativas com a satisfação com a vida e afetividade positiva e relação negativa com a afetividade negativa.

Gestão da sala de aula e perceção de indisciplina: Um estudo com professores angolanos
Authors: Cadete Odete Conceicao , Oliveira Célia , Lopes João
Published: April 2022

A indisciplina na sala de aula constitui uma das maiores preocupações para os intervenientes no processo educativo (professores, gestores de estabelecimentos de ensino, pais) e para a sociedade em geral. Este estudo tem dois objectivos essenciais: análise da relação entre variáveis de gestão da sala de aula e percepção de indisciplina; análise de perfis de resposta de professores, no que concerne à responsabilização pela indisciplina na sala de aula. Participaram no estudo 800 professores angolanos do ensino primário e secundário. Foi utilizado o Questionário de Indisciplina Percebida (Lopes & Oliveira, 2017) e a Behavior and Instructional Management Scale (Martin & Sass, 2010) para avaliar a percepção de indisciplina e a gestão da sala de aula, respectivamente. Os resultados mostram que os professores consideram que pais e alunos são os principais responsáveis pela indisciplina em sala de aula. Verificou-se ainda uma associação entre a gestão de sala de aula e atribuições de responsabilidade pela indisciplina. A análise de perfis evidencia, igualmente, padrões específicos de resposta, de professores que reportam muita, pouca e alguma indisciplina, quanto à atribuição de responsabilidades pela indisciplina. Estes resultados salientam a importância de considerar a gestão de sala de aula no estudo do comportamento dos alunos, em particular da indisciplina em sala de aula, e da perceção dos professores acerca da mesma.

Un problema al que se enfrenta la enseñanza de las ciencias experimentales es la falta de actitudes positivas del alumnado hacia esta disciplina y el creciente desinterés por la misma a medida, el cual avanza con el sistema educativo. Es importante destacar que la motivación y las emociones son elementos fundamentales para aprender ciencias; además, las emociones positivas favorecen el aprendizaje y el compromiso para aprender ciencias. Por ello, y con el fin de involucrar al alumnado en el proceso de enseñanza/aprendizaje y buscar que se responsabilice de su desarrollo y resultado, surge la autoevaluación como una respuesta innovadora. En este trabajo participaron 49 estudiantes de 4º Educación Primaria de un centro educativo del noroeste de España en el curso 2019/2020 con el fin de indagar las emociones que les generaban una serie de actividades prácticas (incluyendo preguntas abiertas y cerradas) dirigidas al estudio de diferentes animales vivos (caracoles y lombrices) antes y después de realizarlas, así como conocer la autoevaluación que hacían sobre su proceso de enseñanza/aprendizaje a lo largo de la realización de la propuesta de actividades. Los resultados respecto a la autoevaluación muestran que los participantes reconocieron lo aprendido en el transcurso de la actividad, haciendo referencia a las características de las lombrices y de los caracoles, pero ninguno indica que aprendió a investigar (aspecto que sí indican en pregunta cerrada). Finalmente, en cuanto a las emociones, los participantes desarrollaron emociones positivas hacia los animales (satisfacción, protección, felicidad…).
Esperando al juez de garantías (a propósito del nuevo Anteproyecto de Ley de Enjuiciamiento Criminal)
Authors: Caamaño Domínguez Francisco
Published: April 2022

La democracia española parece incapaz de reformar su sistema de justicia penal. Ha habido varios intentos para modificar el procedimiento penal y todos ellos han fracasado, entre otras razones, por la fuerte resistencia a conceder, como en los demás países democráticos, la dirección de la investigación de los delitos al Ministerio Fiscal. En este trabajo, con ocasión del anuncio por el Gobierno de España de un nuevo proyecto de Ley de Enjuiciamiento Criminal, se analizan las razones de esa atávica resistencia y las perjudiciales consecuencias que para los derechos fundamentales tiene el hecho de que la dirección de la investigación se atribuya a un juez.

In recent years, interest in the study of platelets, significantly increased due to recent discoveries providing convincing evidence that their functions by are not limited to their participation in the blood coagulation mechanism. Many works are devoted to the study of the functional state of platelets under conditions of acute and chronic alcohol exposure. The results of such studies can be useful for the development of new markers of the degree of alcohol intoxication of the body for the subsequent choice of the method drug correction of disorders caused by acute or chronic alcohol effects. The review summarizes results in vivo and in vitro of studies performed during more than 60 years on the effect of ethanol on the biogenesis, number, morphology and biochemistry of platelets.
