Complexities surrounding the diagnosis and management of hypercalcaemia in pregnancy
Authors: Rodrigo Natassia , Learoyd Diana , Glastras Sarah J
Published: May 2021

Hypercalcaemia in pregnancy is uncommon, with associated adverse obstetric and perinatal outcomes for both the mother and the fetus. Determination of causality is central to its management. Diagnostic imaging techniques are limited during pregnancy and the diagnosis is made more complex by physiological changes in calcium and vitamin D homeostasis in pregnancy. Further, therapeutic options are limited due to safety considerations for the pregnant woman and the developing foetus. Three cases of hypercalcaemia in pregnancy will be presented, highlighting the distinct aetiologies and management strategies for hypercalcaemia in pregnancy and the importance of early measurement of serum calcium in pregnancy screening.

Learning points

There are complex physiological changes in calcium balance in pregnancy, including increased calcium intestinal absorption and renal excretion.

Hypercalcaemia in pregnancy is uncommon but has important potential maternal and foetal complications, making a compelling argument for routine antenatal, calcium screening.

Identifying the cause of hypercalcaemia in pregnancy can be challenging due to the complex placental interplay in biochemical test interpretation and due to safety constraints restricting imaging and surgery.

Acute medical management of hypercalcaemia must be considered in the context of both maternal and foetal well-being, along with gestational age and specific consideration for the safety of the developing fetus in late gestation.
Analysis of the density of wooden components in ancient buildings by micro-drilling resistance, using information diffusion
Authors: Li Xin , Qian Wei , Chang Lihong
Published: May 2021

Wooden components were removed from ancient buildings and used as experimental materials. The drilling curve and feed curve were generated from data collected by a resistograph, and the wood density was predicted by using the information diffusion model. A significant correlation was observed between the data for micro-drilling resistance and wood density. The information diffusion methodology was able to predict the wood density by the nonlinear method very well. Using the two-curve effect weight, when the drilling curve data and the feed curve data were 0.2 and 0.8, respectively, the error was minimum, with an average relative error of 3.82%. Therefore, the data supported on-site ancient building repair work.
General Psychosocial Measures are Affected by the Situation Preceding Assessment: The ‘Arbitrary Distinction’ Between State and Trait Measures is Still Unresolved
Authors: Szabo Attila , Ábel Krisztina
Published: May 2021

General psychosocial measures are assumed to be stable over time. However, such measures may be affected by the situation preceding assessment. In this study 28 participants completed the WHO-5 Well-Being Index, the Subjective Happiness Scale, and the Life Orientation Test which are general measures, and the Positive Affect Negative Affect Schedule and the Feeling Scale which are state measures. Subsequently, the first part of ‘Mega Disasters Nagasaki The Forgotten Bomb’ documentary was presented to the participants. Following the intervention, they completed the same measures again. State measures of negative affect increased, feeling state decreased as expected, but retrospectively measured well-being as well as the index of optimism also decreased. There were large individual differences. The findings indicate that general measures, assumed to be stable over time, are influenced by the situation. Therefore, there is a need for reporting, as well as controlling, the events preceding their measurement. The implication of these findings is that hundreds of empirical results based on general or trait measures may be invalid if any event preceding their assessment had an emotional impact.
Environmental Attitudes and Recycling Behaviour in Primary School Age: The Role of School and Parents
Authors: Šorytė Dovilė , Pakalniškienė Vilmantė
Published: May 2021

This study aimed to investigate the relationship between environmental attitudes and recycling behaviour in primary school age, and to evaluate the role that school and parents play in the prediction of children’s attitudes and behaviour. Primary school pupils aged 8–11 years (n = 116), their parents and their class teachers participated in the study. During the structured face-to-face interviews, children answered questions about their recycling behaviour and environmental attitudes (i.e. eco-affinity and eco-awareness). Parents provided answers on their recycling behaviour, verbal modelling of the behaviour, incentives used when a child recycles waste, and environmental attitudes, while class teachers provided information about the recycling in children’s school. Structural equation models were tested with a purpose to evaluate the role of different independent variables, i.e. only school, only parental factors, or both, when predicting child recycling behaviour. Results of the study showed that children’s environmental attitudes had no significant links to their recycling behaviour. The only factor that appeared to be significant in the prediction of child behaviour was parental recycling behaviour. Furthermore, recycling in schools predicted pupils’ eco-awareness. Based on the study findings, it would be worthwhile to promote more practical training of pro-environmental behaviour, and to strengthen children’s eco-affinity.

A prospective longitudinal cohort study was carried out in patients announced for major elective surgery, with orotracheal general anesthesia, at the “Carlos Manuel de Céspedes de Bayamo Provincial Hospital, from the Cauto region during the period from January 1, 2016 until December 31, 2018; with the objective of identifying the risk factors hypothetically related to the prognosis of intraoperative awakening. The exposed cohort consisted of two patients who experienced intraoperative awakening in the study period, and met the inclusion criteria. The magnitude of the associations was estimated by calculating the relative risks (RR). Age equal to or greater than 65 years, difficult intubation, patients with ASA III and IV physical status, and chronic alcohol ingestion, were the surgical risk factors depending on the patient, associated with the prognosis of awakening. Intraoperative in patients announced for major elective surgery, under general orotracheal anesthesia, although not significantly; while the female sex did not present an association. The time of surgery equal to or greater than four hours, was constituted in the surgical risk factor depending on the surgery, related to the prognosis of appearance of intraoperative awakening in patients announced for major elective surgery, with orotracheal general anesthesia.

BACKGROUND AND OBJECTIVES:

Early determination of prognosis is important in neonates with hypoxic-ischemic encephalopathy (HIE). Our objective was to test scoring systems developed earlier (original scoring system) and develop new prognostic models.

METHODS:

Secondary analysis of data from the multicenter randomized controlled trial of longer, deeper, or usual care cooling in neonatal HIE (NCT01192776) that enrolled 364 neonates diagnosed with moderate or severe HIE. The primary outcome was death or moderate or severe disability at 18 to 22 months, and secondary outcome was death during initial hospitalization. Testing of early neurologic clinical examination (<6 hours of age) and the original scoring system for prognostic ability was done, followed by development of new scoring systems and classification and regression tree (CART) models by using early clinical variables (<6 hours of age).

RESULTS:

For death or disability, the original scoring system correctly classified 75% (95% confidence interval: 69%–81%), whereas the new scoring system correctly classified 78% (73%–82%), and the CART model correctly classified 76% (72%–81%). Early neurologic clinical examination also had a correct classification rate of 76% (71%–80%). Depth and duration of cooling did not affect prediction. Only a few components of the early neurologic examination were associated with poor outcome. For death, the original scoring system correctly classified 72% (66%–77%), the new scoring system 68% (63%–72%), the new CART model 87% (83%–90%), and early neurologic evaluation 81% (77%–85%).

CONCLUSIONS:

The 3 models (scoring system, CART, and early neurologic evaluation) were comparable in predicting death or disability. For in-hospital death, CART models were superior to scoring systems and early neurologic examination.

Published: May 2021

To improve crop development, commercial substrates are recommended without distinction for different crops and/or varieties without considering their characteristics and needs; therefore, their composition and nutritional condition must be studied for each type of plant in its initial formation.The objective of this study was to evaluate the development of shoot and root systems of two lettuce cultivars produced in 10 different substrates. Great Lakes and Simpson Black Seed cultivars were evaluated in 10 substrates formulated by mixing a commercial substrate, organic compounds (swine, cattle, poultry) and sugarcane bagasse. Great Lakes cultivar had a higher development of the aerial part, whereas Simpson Black Seed cultivar had a more robust root system. The substrate with swine and poultry favored the development of the aerial part of the seedlings and lettuce, while the substrates with 33% of sugarcane bagasse improved the development of the root system. The commercial substrate used in isolation showed the lowest performance.

Published: May 2021

Aedes aegypti L. is the mosquito vector of yellow fever, dengue, zika, and chikungunya viruses. The prevention and control of such diseases usually rely on the use of chemicals, that can cause harm to human health and the environment. Vegetable oils with larvicidal activity are used as an alternative tool to control this insect. This study aimed to evaluate the larvicidal activity of vegetable oils from Caryocar coriaceum, Mauritia fIexuosa, Carapa guianensis, Copaifera langsdorffii, Ricinus communis and Cocos nucifera against A. aegypti larvae. The experiment was divided into two bioassays. In the first, a completely randomized design was used with seven treatments (six vegetable oils at 500 ppm and one control with four replications). The number of dead larvae was evaluated 24, 48, 72, 96, and 120 h after exposure. In the second bioassay, the most efficient vegetable oils from the first bioassay (C. coriaceum and M. flexuosa) were used at the concentrations of 0, 500, 1000, 1500, 2000, and 2500 ppm, with four replications. The number of dead larvae was evaluated according to the first bioassay. All oils used had larvicidal activity on third instar stage larvae of A. aegypti, with greater efficiency 120 h after exposure. The oils of C. coriaceum and M. flexuosa at 2500 ppm had the best efficacy in the larvae control. The LD10, LD50, and LD90 of M. flexuosa oil recommended for controlling larvae are 234, 648, and 1794 ppm, respectively.
Modern Houses in a Folk Architectural Environment
Authors: Ispán Ágota Lídia
Published: May 2021

From the 1960s, the hip-roofed, cube house became the dominant type of dwelling throughout Hungary. Architects and ethnologists raised objections to the resulting “alien” appearance of settlements, and eventually even the authorities attempted to slow down the spread of these dwellings, with little success. In the Őrség region, with its characteristic folk architecture, the transformation was already visible by the 1970s, despite the region having some of the worst socioeconomic conditions in the country. Before the establishment of the Őrség Landscape Protection Area in 1978, the debates between the proponents of socialist modernization and those wishing to promote nature and the conservation of folk heritage were becoming increasingly heated. One such conflict was based on the difference of opinion between those wishing to preserve the architectural heritage, and the demands of local inhabitants for the modernization of their housing. In the present paper, in relation to the Őrség region, and to a lesser extent Vendvidék (Porabje), I examine how the building stock was transformed, what means were used to try to prevent the spread of the modern cube houses, what plans were put in place to preserve the traditional architectural features of the region, and with what kind of new functions attempts were made to solve the utilization of old buildings.
Traditional Ecological Knowledge in Connection with Non-Domesticated Animals in the Slovenian and Hungarian Borderland
Authors: Ulicsni Viktor , Babai Dániel
Published: May 2021

Although a significant proportion of folk knowledge of nature concerns knowledge of invertebrates and vertebrates living in the wild, very little ethnozoological research has been carried out in Central Europe focusing on the whole fauna. In writing the present paper, our aim was to contribute to filling this gap by interviewing 40 local farmers who are particularly knowledgeable on this topic, half of them from the Őrség region of Hungary, and half from the neighboring villages in Slovenia, and by recording their knowledge with respect to non-domesticated animals.

Our research identified the second highest number of taxa (242 species-level folk taxa) in terms of investigations carried out in the Hungarian language area in relation to the entire fauna. These included 129 invertebrate folk taxa, 73% of which were called by a species-specific name. They also included 109 vertebrate folk taxa, 103 of which had a separate species-level local name. In the case of two groups (butterflies and mammals), we also investigated attributes that were important and salient from the point of view of species knowledge: morphology and size were of particular relevance in relation to mammal species; while salient habitat features and frequency were relevant in relation to butterfly species. In the case of both groups, usefulness was the least important factor.

Despite the general erosion of traditional ecological knowledge in Europe, these recently collected data indicate that a rich, vibrant knowledge is still to be found among the Hungarians whom we interviewed in the Őrség region and the neighboring villages in Slovenia. The especially large number of recorded folk taxa, and the accurate knowledge required to differentiate between them confirm, that even today it is worth carrying out investigations on this topic in East Central Europe in the interests of obtaining knowledge of, and conserving cultural and natural values.
Connectivity of regional systems of consumer goods reproduction
Authors:   Bashkir State University, Ufa, Russian Federation, Timiryanova Venera M.
Published: May 2021

Relevance. The question of how to achieve a more stable economic reproduction and how to expand it is of prime importance as reproduction determines the development of the whole economic system. Due to the constant economic transformations and the so-called 'networkization' of many processes, more research is needed into the spatial organization of reproduction, in particular the intraregional and interregional relationships between its elements. Research objective. This study aims at showing the spatial connections between phases of reproduction on the regional and municipal levels. Data and methods. The study relies on tools and methods of spatial econometric modelling, which includes calculations of univariate and bivariate global and local Moran's indices and diagrams of their dispersion. We constructed an adjacency matrix for Russian regions and municipalities. Overall, our study uses the data on 2,337 municipalities in 84 Russian regions. Results. It was found that the phase of consumption followed by the phases of distribution and exchange have the highest degree of connectivity. Spatial connectivity between the phases was the most pronounced in the case of retail trade and consumption and was much weaker in the case of wholesale trade and production. The analysis of the municipal-level data has revealed some previously undetected relationships between peripheral areas located near regional borders. Conclusions. In this study, we consider reproduction as a spatially organized economic system with interconnected, territorially dependent phases. Such approach provides us with new insights into the ongoing processes in the national economic space.

Objective. The aim of this study was to clarify the effect of a stable concentration of propofol on interictal high‐frequency oscillations (HFOs), which may contribute to identifying the epileptogenic zone intraoperatively for resection surgery.

Methods. Nine patients with drug‐resistant focal epilepsy who underwent invasive pre‐surgical evaluation with chronic subdural electrodes were recruited. Five‐minute electrocorticograms during wakefulness, slow‐wave sleep, and under a stable brain concentration of propofol were recorded with the same electrodes. In each patient, 1–10 pairs of electrodes were selected for both electrodes with EEG changes within 5 seconds from the ictal onset (ictal pattern for 5 seconds [IP5]) and those outside the area of IP5 with no interictal epileptiform discharges (non‐epileptiform [nEPI]). The numbers of ripples (80‐250 Hz) and fast ripples (>250 Hz) were measured semi‐automatically using an established algorithm. Statistical testing was performed with a mixed effect model.

Results. Thirty‐seven pairs of electrodes from nine patients were analysed for IP5 and 29 pairs from seven patients were analysed for nEPI. The numbers of HFOs differed between the areas (IP5 and nEPI) and among the conditions (wakefulness, slow‐wave sleep, propofol anaesthesia) (all p <0.01). The HFO occurrence rates were significantly higher for IP5 than those for nEPI in all conditions (for both ripples and fast ripples in all conditions; p <0.01).

Significance. The occurrence rates of HFOs for IP5 were significantly higher than those for nEPI under propofol anaesthesia. These are fundamental findings for intraoperative HFO analysis, however, the following limitations should be considered: physiological HFOs could not be completely differentiated from pathological HFOs; in order to apply an HFO detector, an appropriate cut‐off threshold is needed; an artefact of the impulse response filter appears as an HFO; and the series was comprised of a small number of heterogeneous patients.

Most families with genetic epilepsy with febrile seizures plus show a mutation in the sodium channel alpha 1 subunit gene, however, but there is much phenotypic heterogeneity and focal epilepsy remains relatively rare. Here, we report a family with electroclinical features indicative of temporal‐parietal‐occipital carrefour epilepsy with common occurrence of post‐ictal migraine. We studied a four‐generation family including nine affected subjects by means of EEG and MRI. Genetic testing was performed by targeted re‐sequencing (gene panel). In most patients, seizure semiology included cognitive, autonomic, and emotional symptoms, eventually evolving towards sensory visual phenomena. Focal sensory vestibular seizures and changes in body perception were also reported in some cases. Post‐ictal migraine was common, occurring in five out of the six (83%) epilepsy patients. A missense mutation (c.1130 G>A; p.R377Q) affecting the S5‐S6 segment (pore region) of the sodium channel alpha 1 subunit was identified in all affected and four unaffected subjects. Temporal‐parietal‐occipital carrefour epilepsy is part of the genetic epilepsy with febrile seizures plus spectrum. The electroclinical features in this family support the involvement of a genetically impaired neural network. High prevalence of post‐ictal migraine suggests the role of posterior brain areas in the clinical expression of this gene defect.

We present pharmacokinetic data during pregnancy and lactation for brivaracetam, lacosamide and perampanel based on two case studies. Patient 1 used brivaracetam as monotherapy and gave birth to twins. Patient 2 used a combination of brivaracetam, lacosamide and perampanel. In both patients, serum drug concentrations were monitored throughout the pregnancies. Drug concentrations were also analysed in umbilical cord blood at birth, in serum from the offspring and in breastmilk after five days and 3–11 weeks. There were minor changes in concentration/dose‐ratios for brivaracetam and lacosamide. The mean milk/serum ratios for brivaracetam and lacosamide were 0.71 and 0.83, respectively, five days and 3–5 weeks after delivery. The perampanel serum concentration increased by up to 80% in Patient 2 during the last part of gestation. The mean milk/serum‐ratio for perampanel was 0.13, unchanged from five days to five weeks after delivery. Whereas serum concentrations of brivaracetam and lacosamide remained fairly stable throughout pregnancy, perampanel concentrations seemed to steadily increase towards the end. The distribution to milk was considerable for brivaracetam and lacosamide and low for perampanel. More studies on mother‐infant pairs are warranted to confirm these results in larger groups.

Published: May 2021

The study of dementia and epilepsy may provide particular insight into behavioural alterations. We describe a rare case of ictal aggressive behaviour in a patient with focal epilepsy associated with a non‐dominant dorso‐lateral prefrontal lesion. During focal seizures, our patient showed intense agitation and anger, for a long time misinterpreted as psychogenic attacks, which disappeared after epilepsy surgery. The defined anatomical origin of such ictal emotional behaviour is not fully understood, however, the dorso‐lateral prefrontal area appears to correlate less frequently with aggressiveness compared to the antero‐mesial area. We describe the electroclinical data of our patient and provide a brief review of the mechanisms underlying aggressive conduct in epilepsy and dementia. An understanding of this mechanism could help to clarify the neural basis and treatment of violence associated with these and other neurological disorders. [Published with video sequence].

В работе представлены оценки индивидуальной динамики индекса массы тела (ИМТ) российских мужчин и женщин, выполненные на данных Российского мониторинга экономического положения и здоровья населения НИУ-ВШЭ 1994-2018 гг. Панельная структура данных позволила оценить индивидуальную динамику ИМТ без существенного вклада кросс-секционной составляющей в возрастной профиль ИМТ в рамках эконометрической модели возраст–период–когорта. Эмпирические оценки выявили монотонный рост ИМТ мужчин в 2001-2011 гг. В работе показано, что ИМТ женщин на протяжении жизни растет до 60 лет, мужчин – примерно до 40 лет. Выявлено также, что существует тенденция роста ИМТ в молодых поколениях мужчин. У женщин подобный рост сменяется спадом, начавшимся с поколения женщин 1950 г. рождения. Полученные в работе оценки профилей ИМТ мужчин и женщин в трех измерениях (возраст–период–когорта) могут служить целям совершенствования политики в области охраны здоровья населения.
Analytical properties of sample paths of some stochastic processes
Authors: Rozora I. V.
Published: May 2021

The study of the analytical properties of random processes and their functionals, without a doubt, was and remains the relevant topic of the theory of random processes. The first result from which the study of the local properties of random processes began is Kolmogorov’s theorem on sample continuity with probability one. The classic result for Gaussian random processes is Dudley’s theorem. This paper is devoted to the study of local properties of sample paths of random processes that can be represented as a sum of squares of Gaussian random processes. Such processes are called square-Gaussian. We investigate the sufficient conditions of sample continuity with probability 1 for square-Gaussian processes based on the convergence of entropy Dudley type integrals. The estimation of the distribution of the continuity module is studied for square-Gaussian random processes. It is considered in detail an example with an estimator (correlogram) of the covariance function of a Gaussian stationary random process. The conditions on continuity of correlogram’s trajectories with probability one are found and the distribution of the continuity module is also estimated.
The properties of the queuing model with the parallel structure
Authors: Chechelnitsky O. A.
Published: May 2021

The present article is devoted to research the multi-channelk model with the parallel structure. It means that we consider the model which consists of two infinite-server queues.

The service time in the each system has general function of distribution. In this case the stochastic dynamic of our model cannot be defined by Markov chain. As a result, analysis of such models is much more difficult than that of the corresponding Markovian queueing models. Besides we assume that customers arrive to our model according a bivariate Poisson input flow. This input process is characterized by the fact that customers arrive according to a bivariate Poisson flow simultaneously. We consider the number of customers in the systems at time t. This stochastic process describes the state of our model. In present paper we find the limit joint distribution of the number of customers in the systems. In a general way (by differentiating the corresponding generating function.) we obtain the main characteristics of this distribution, such as the expected number of customers in the nodes, its variance and correlation. In the case when parameters of our model dependent on the parameter n (number of series) the limit normal distribution was obtained for the service process in the stationary regime.

EXCITATION OF FREAK WAVE BY NATURAL OSCILLATIONS OF THE WATER BODY
Authors: Anakhov P. V.
Published: May 2021

In linear theory the formation of extreme waves their existence is interpreted as a local superposition of surface monochromatic waves. Natural water areas are resonators that have their own set of natural oscillations – standing waves of stable spatial structure and fixed period. In the spectra of waves of many water bodies of World Ocean observed double high waves, this is explained by the tidal-seiche resonance. During a storm, the energy of natural oscillations increases ten times the background energy, during a tsunami it can increase up to three orders of magnitude. Examples of the effects of natural oscillations on the coast are given, and it is reported about the increased probability of the occurrence on the coast freak waves. Additionally, it is noted that natural oscillations in water mass are a normal state for any body of water at any time of its existence. The corresponding indices of the water fluctuations of the water basins are given. The events of extreme waves during the accidents at DniproHES (Zaporizhia) on August 18, 1941, and the Kurenivsky dam (Kyiv) on March 13, 1961, are presented.
The excitement of the freak wave can be interpreted as enhancing the natural oscillations of the water basin, represented by standing waves of stable spatial structure, fixed period and high probability of waves in the water body. This does not contradict the linear theory of the resonant formation of abnormally high waves.
The purpose of the article is to investigate possible sources of the excitement of freak waves, the results are proposed to be implemented in the development of countermeasures to the destructive process. However, the waves carry out both destructive and creative work. A task is presented, which involves the development of measures to stimulate extreme waves. This will increase electricity generation.
Affiliation of dam-break waves to freak waves can be doubtful. However, they formally correspond to the classical condition of double exceeding the significant wave height. Most water basins are integral anthropogenic sites. The variability of both natural and anthropogenic environments forces the overriding of systematization and definition. It is proposed to attribute extreme waves of dam-break waves to freak waves.
Relationship between Personal Characteristics and the Academic Performance of High School Students
Authors: Mishkevich A.M.
Published: May 2021

The influence of personality traits on performance at school is regularly researched in various studies, including meta-analytical studies. As personality traits are quite stable, they scarcely can be changed. According to the five-factor theory, the influence of inborn traits on behaviour is mediated by acquired characteristic adaptations. Which means that it is easier to change characteristic adaptations in order to correct behaviour, rather than traits. The survey was conducted among 135 Russian adolescents, ages from 14 to 17 (M=15.19; SD=0,71). The traits of the Big Five and four variations of reflexive characteristic adaptations were measured. Performance was also counted – the average score in all subjects for each student in the past academic year. As a result, we have found correlations of conscientiousness and openness with performance. This research has shown that reflexive characteristic adaptations are a more trustworthy performance correlate than traits. We have discovered that meta-attitude toward conscientiousness contributes, in a unique way, to performance at school. This contribution depended on neither gender differences nor the differences in the conscientiousness trait itself. The study has also revealed that the correlations between performance and openness can mostly be explained by gender differences. Whereas meta-attitude toward openness makes a significant contribution to the variation of successes in studying regardless of the gender differences and the differences in the openness treat itself. Thus, the research has shown, that reflexive characteristic adaptations contributes, in a unique way, to the prediction of performance at school.

Small Local Earthquake Detection Using Low-Cost MEMS Accelerometers: Examples in Northern and Central Italy
Authors: Cascone Valeria , Boaga Jacopo , Cassiani Giorgio
Published: May 2021

This study evaluates the seismicity detection efficiency of a new low-cost triaxial accelerometer prototype based on microelectromechanical systems (MEMS) technology. Networks of MEMS sensors were installed in telecommunication infrastructures to build two small arrays in northern and central Italy. The sensor prototypes recorded major earthquakes as well as nine small seismic events with 2.0<ML<3.0. Where possible, MEMS were compared to the closest high-quality seismic stations belonging to the national accelerometric network. The comparison, in terms of peak ground accelerations and spectral responses, confirms that the signals are in good agreement. The tested inexpensive MEMS sensors were able to detect small local events with epicentral distances as large as 50 km and provided an efficient characterization of the main motion parameters. This confirms that the proposed accelerometer prototypes are promising tools to integrate into traditional networks for local seismicity monitoring.
Raspberry Shake Instruments Provide Initial Ground-Motion Assessment of the Induced Seismicity at the United Downs Deep Geothermal Power Project in Cornwall, United Kingdom
Authors: Holmgren Joanna M. , Werner Maximilian J.
Published: May 2021

Raspberry Shake (RS) seismographs offer the potential for affordable and citizen-led seismic monitoring in areas with few publicly available seismometers, especially in previously quiescent regions experiencing induced seismicity. However, their scientific and regulatory potential remains largely untested. We examine the ground motions recorded by 11 RS and one broadband station within 15 km of the United Downs Deep Geothermal Power (UDDGP) project in Cornwall, United Kingdom, to evaluate the RS network’s suitability to provide an initial ground-motion assessment of the region. To date, the British Geological Survey (BGS) has reported 232 induced events originating at UDDGP since flow testing began in summer 2020, with two events exceeding local magnitude (ML) 1.5. Although the RS accelerometers are too noisy for UDDGP’s microseismic events, the vertical geophones are useful. Peak ground velocity observations are consistent with relevant ground-motion models, whereas peak ground acceleration (PGA) values are greater than predicted. Regional trends in the PGA levels are likely caused by path effects. Finally, RS estimates of ML are similar to those reported by the BGS. For sparse national seismic networks, RS stations can enable a preliminary evaluation of seismic events and their ground motions.
Expanded Education and Global Integration: Solidarity and Conflict
Authors: Frank David John , Meyer John W.
Published: May 2021

The dramatic expansion and rising social significance of education integrates the world’s populations and elites under a common ontological frame and on the basis of common human identities rooted in educational status and cultural content. Education-based integration supports institutions of solidarity – large-scale organizational structures in national and global societies, and common cognitive and normative cultural materials. It also creates expanded grounds for conflict. In this essay, we review the matter.
Towards a Praxis of Educational Solidarity
Authors: Bajaj Monisha , Tow David
Published: May 2021

In this article, the authors locate examples of solidarity in the structures and practices of two educational institutions in Northern California. Applying a taxonomy of solidarity drawn from Gaztambide-Fernández (2012) to two schools’ responses to Covid-19, the authors delineate serendipitous acts of solidarity from intentional and deliberate solidarity praxes that have been deepened during the pandemic. This article sheds light on possibilities to reimagine educational solidarity post-Covid in order to further the process of humanizing education and advancing greater equity and justice.

Published: May 2021

The effects of flurprimidol and paclobutrazol, treatments as preplant bulb soaks on plant height, growth parameters and other properties of Narcissus tazetta L. grown in pots were investigated. Bulbs were soaked in flurprimidol at 0, 10, 20 mg L-1 or paclobutrazol at 0, 100, 200 mg L-1 before planting. The effects of gibberellin inhibitors on the flower number, flowering time, flower life, plant height, leaf length and quantitative measurements (specific leaf area, leaf area ratio, leaf thickness, leaf weight ratio and stem weight ratio) were determined. When narcissus reached to the sale stage, plants were taken to the laboratory where the temperature stable at 20°C to evaluate the postproduction quality. The shortest plant height (6.25 cm, 63% shorter than control) was obtained from the 20 mg L-1 flurprimidol application. Plants applied with 200 mg L-1 paclobutrazol were 59% shorter than control with 7.00 cm plant height. Gibberellin inhibitors also shortened the leaf length and increased the leaf thickness, whereas decreased leaf area ratio and specific leaf area by shortening the plant height. The effects of gibberellin inhibitors on plant height continued after harvest (production) in marketing and consumer (laboratory) conditions. The plant heights of treated plants were 10.87 (20 mg L-1 flurpirmidol) and 10.37 (200 mg L-1 paclobutrazol) cm, while with the control plants were 26.75 cm in with laboratory conditions.

Antecedentes: se analiza, desde la perspectiva psicológica forense, los factores sociodemográficos y características del abuso sexual. Para ello, se identifican factores de vulnerabilidad, riesgo y protección. Objetivos: evaluar los factores de vulnerabilidad, riesgo y protección en niños, niñas y adolescentes víctimas de abuso sexual en Lima Norte. Método: esta investigación es de tipo básica, transeccional, de nivel descriptivo, no experimental. La unidad de análisis la componen niños, niñas y adolescentes víctimas de abuso sexual, con edades entre 3 y 18 años. La fuente de análisis son 55 informes periciales de estas víctimas atendidas en un servicio de psicología forense de Lima Norte. Se emplearon cuatro instrumentos de verificación de factores: sociodemográficos-abuso sexual, vulnerabilidad, riesgo y protección; validados según juicio experto y fiabilidad por alfa de Cronbach. Resultados: la mayoría de las víctimas se registran como adolescentes mujeres, provenientes de familias nucleares: 20% migrantes que viven en pobreza y pobreza extrema; 96.4% abusadas bajo amenaza. Además, se encontraron altos porcentajes de factores de vulnerabilidad en victimizaciones previas y en alteraciones psicológicas. Conclusiones: los mayores porcentajes de riesgo se encuentran en las relaciones intrafamiliares y en cuanto a los factores protectores, se encuentra un bajo nivel de habilidades sociales.

Uno de los más importantes sistemas en la sociedad, es la familia, y con ella la comunicación que surge entre los miembros. Por tal motivo, se analizó las evidencias psicométricas de la Escala de Comunicación Familiar (FCS). La muestra fue de 210 estudiantes universitarios peruanos, el 46.19% fue de universidad pública y el 53.81% fue de universidad privada, la cual estuvo conformada por 44.29% hombres y 55.71% mujeres, teniendo como participantes en la región Costa 85.25%, Sierra 11.44% y Selva 3.31%. Los reactivos indicaron unos apropiados índices de ajuste, además, el análisis factorial confirmatorio (AFC) evidenció la validez de la estructura interna y la unidimensionalidad de la escala, proporcionando los siguientes resultados: X2= 79.370, gl =35, X2/gl = 2.26, CFI = .945, TLI = .929, RMSEA = .078, SRMR = .046. A su vez, la escala FCS tiene una correlación positiva con la escala de funcionamiento familiar y necesidad de aprobación social; sin embargo, presenta una relación inversa con la escala violencia filio parental. Por otro lado, la confiabilidad fue de α .939 y ω de .94, representando de esta forma la validez del instrumento. Finalmente, se presentó invarianza, tomando en cuenta el sexo y gestión de universidad, dando como resultado que los participantes entendieron y respondieron de forma similar el cuestionario.

Published: May 2021

El presente artículo pretende analizar el paradigma sociocrítico en su relación con la investigación científica, por ello previamente se define el paradigma como la representación del compromiso de los integrantes de una comunidad científica con una forma de ejercer o guiar la práctica científica. Asimismo, se busca conceptualizar el paradigma sociocrítico, el cual se sustenta en la crítica social con tendencia a la autorreflexión, entendiendo que los conocimientos se construyen en base a inquietudes  que surgen de las necesidades de determinados grupos sociales (Maldonado, 2018), en donde el investigador a diferencia del paradigma positivista deja de ser solo un  observador para convertirse en un generador de cambio que facilite las transformaciones sociales. Por otro lado, se analiza los orígenes, postura de autores, características, principios y aplicaciones en distintas especialidades. Finalmente, a través de las conclusiones se busca reflexionar acerca de la aplicabilidad del paradigma sociocrítico en nuestra sociedad.
