Published: May 2023

El objetivo fue analizar las preocupaciones relacionadas con la COVID-19 y el ajuste emocional de los adolescentes de Ecuador, estudiando las diferencias en dos momentos temporales a los 3-6 meses y a los 6-9 meses del inicio de la pandemia. Se evaluaron el ajuste emocional a través del DASS-21 y las preocupaciones ante la COVID-19 a un total de 902 participantes. Un 79,90% fueron chicas. Sus edades estaban comprendidas entre 12 y 17 años (M = 15,30; DT = 1,28). Los resultados indican diferencias entre las muestras en los diferentes momentos temporales indicando una mayor presencia de sintomatología ansioso-depresiva, estrés y preocupaciones en el momento temporal excepto para las preocupaciones económicas que son mayores en el momento uno. Las preocupaciones ante la COVID-19 se relacionan de manera negativa con el ajuste emocional. En conclusión, analizar el impacto psicológico en el ajuste a la etapa de la adolescencia puede ayudar a profundizar en las consecuencias de la pandemia a corto y largo plazo.

Fruits play a primary role in the diet and several studies based on health report the importance of fruits because of their nutritional components that serve a protective role against many diseases. The most prevalent non-timber forest products and significant sources of food and medicine are wild edible fruits (WEFs). The WEFs must greet potential sources of crucial nutrients majorly of children and old age people suffering from malnutrition. The Rangayyanadurga Four-Horned Antelope (FHA) wildlife sanctuary, situated in Jagalur, of central Karnataka, India, harbours many indigenous, unexploited, edible, and unfamiliar fruits, which are important sources of income and food for rural communities. These fruits play a crucial role in health care and they contain several phytochemicals like, flavonoids, polyphenols, glycoside, tannins, essential oils, malic acid, and oleanolic acid. The wild edible fruits have health benefits such as anticancer, antidiabetic, anti-diarrhoeal, anti-inflammatory, antimicrobial, anti-hypolipidemic, antiscorbutic, antioxidant, neuroprotective and piles curing properties. The research in this review focuses on 15 edible wild fruit species from 11 families that have been spotted in the Rangayyanadurga Sanctuary and was tabulated with botanical name, mode of consumption, bioactive compounds and biological effects. The more signified families are Rutaceae, Rubiaceae, Moraceae, Apocynaceae, Boraginaceae, Cucurbitaceae, Fabaceae, Arecaceae, Myrtaceae, Cactaceae and Rhamnaceae. The findings pointed to the need for additional research into the nutritional composition, environmental impact, and therapeutic properties of wild edible species as well as the potential benefits of the different WEF types identified here as neuroprotective agents.

Del «silencio» de la ley a la «ley del silencio»: ¿quién teme a la lucha de la Inspección de Trabajo contra el acoso moral en las Administraciones públicas?
Authors: Molina Navarrete Cristóbal
Published: May 2023

En este trabajo se realiza un comentario crítico del denominado CT 34/2003, elaborado por la DGITSS para excluir el acoso moral en el trabajo de la actuación inspectora desde la perspectiva preventiva. La consecuencia más inmediata en el plano práctico es la exclusión de su ámbito de actuación de los funcionarios públicos, cualesquiera que sea el ámbito administrativo donde presten sus servicios. De este modo, tales trabajadores, pese a estar incluidos dentro del ámbito de aplicación de la LPRL, se verán obligados bien a ponerse en manos de la Inspección de Servicios, que hasta el momento han acreditado una actuación muy deficiente, cuando no nula al respecto, por cuanto desconocen de raíz el marco normativo aplicable, bien a conducir sus actuaciones por el intrincado y proceloso mundo de la responsabilidad patrimonial de las Administraciones Públicas, en línea con lo sucedido en el supuesto de la STS 23-7-2001. Para el autor, sin embargo, tal criterio técnico choca frontalmente con la legalidad vigente en esta materia así como con el propio criterio técnico evidenciado por el órgano científico técnico especializado de la Administración General del Estado, por lo que la perplejidad no puede ser mayor. De ahí que, analizando tanto el concepto jurídico-preventivo de «acoso moral en el trabajo» como los fundamentos jurídicos de su tutela, a la luz del ordenamiento español de Seguridad y Salud, que hasta el momento había pasado por ser uno de los más modernos e innovadores del mundo, no obstante el fuerte revés de su incumplimiento práctico –quizás por esa misma ambición normativa–, el autor proponga la no vinculatoriedad de tal criterio para las Jefaturas Provinciales de Inspección de Trabajo y Seguridad Social. La inaplicación del criterio técnico, en tanto se determine su nulidad, o su corrección en vía interpretativa por los propios inspectores, no sólo tiene fuerte asidero legal sino que incluso viene posibilitado por el mismo CT 34/2003, que ha dejado un resquicio abierto para aplicar la legislación preventiva en preferencia a la laboral.
La doble escala salarial como instrumento de desigualdad retributiva
Authors: Purcalla Bonilla Miguel Ángel
Published: May 2023

La sentencia del Tribunal Superior de Justicia de Cataluña de 31-1-2003 (asunto Nissan) constituye un nuevo capítulo en la litigiosidad que viene rodeando, desde hace casi una década y con el frontispicio de los asuntos Hertz y Damm (ambos resueltos en 1996), a la doble escala salarial. En efecto, los convenios colectivos y las prácticas de empresa en diversos sectores productivos (automoción y transporte de viajeros, especialmente) vienen incorporando dobles escalas salariales que penalizan económicamente a los trabajadores de nuevo ingreso, ya sea con un salario global directamente menor, ya con un complemento que deja de abonarse, ya con la introducción de fórmulas de cálculo de algún complemento que perjudican a dicho colectivo de trabajadores. A propósito de esta problemática, el presente trabajo analiza con detalle la jurisprudencia y la doctrina judicial al respecto, sistematizando sus claves interpretativas y desmenuzando minuciosamente la casuística para calibrar cuándo y bajo qué parámetros se admiten las dobles escalas salariales. Al tiempo, este análisis da un paso cualitativo más, pues, con el aderezo de criterios jurídicos y sociológicos, apunta diversas alternativas negociales prácticas (participación retributiva y cláusulas de inaplicación salarial) al desigual trato remuneratorio que acarrea la doble escala salarial.
La prestación por desempleo derivada del despido
Authors: Viqueira Pérez Carmen
Published: May 2023

Este trabajo ha sido seleccionado y ha obtenido el Accésit Especial Premio Estudios Financieros 2003 en la Modalidad de Derecho del Trabajo y Seguridad Social.
La Ley 45/2002 lleva a cabo una reforma del sistema de protección por desempleo que, aun dejando inalterado gran parte del esquema sobre el que la protección descansa, afecta a alguno de sus aspectos fundamentales. Uno de esos aspectos fundamentales que la norma modifica es el acceso a la prestación.
En este ámbito, la modificación más llamativa –aunque no la más importante– es la relativa a la exigencia de suscripción del «compromiso de actividad» como nuevo requisito de acceso a la protección. Pero la norma también altera el requisito de acceso «clásico»; la involuntariedad en la pérdida del empleo [o, en términos técnicos, sobre la situación legal de desempleo], mediante la modificación de la situación legal de desempleo por despido. Uno y otro cambio constituyen, en el plano dogmático, las más importantes repercusiones de la reforma, por cuanto inciden en los pilares básicos sobre los que descansa la noción de desempleo protegible, y, desde el punto de vista técnico-jurídico, representan las modificaciones de mayor trascendencia, por lo que suponen de ruptura con la normativa anterior y porque de ellas trae su causa la mayoría de las restantes modificaciones introducidas por la reforma.
El hondo calado que tiene la nueva definición de la situación legal de desempleo por despido se evidencia si se tiene en cuenta que con ella no sólo se redefine uno de los elementos clave que abre o cierra el acceso a la protección, sino que, además, fruto de esta modificación, resultan también alterados algunos aspectos importantes de la dinámica del derecho, como son su nacimiento o su suspensión. Puede decirse, por eso, que realmente la norma articula un nuevo régimen de la prestación originada por el despido, con todo lo que ello implica. Y es que la dinámica de la prestación por desempleo derivada de despido actúa como patrón de la dinámica que rige la prestación derivada de la práctica generalidad de los restantes supuestos extintivos que dan lugar al acceso a la protección. Al análisis de los problemas que puede plantear la aplicación de esta regulación se dedica este estudio.
Incidences and Trend of Marine Accident Fatalities in Various River Routes Connecting the Major Sea Ports of Nigeria
Authors: Prince Ogboeli Goodluck, , Azuka Iyama, William , Williams Onuegbu
Published: May 2023

The study investigated the incidences and trends of marine accident fatalities in various river routes connecting the major sea ports in Nigeria. This was necessitated by the various cases of deaths, drop in government revenue and presence of wrecks from abandoned boats and ships in the coastal waters. The cross-sectional survey research design was adopted relying on both primary, secondary data and the use hypothesis to draw conclusions. Primary data was got through acquisition from satellite imageries from the loading and exit point of various river routes and designed questionnaires distributed while secondary data such as accident and disaster occurrence was collected several marine sector regulatory agencies in charge of the marine sector for a period of thirty (30) years (1989 to 2018). The study showed that river route incidence is dependent primarily on the population of the destination route and its frequency of usage. Although, other factors such as poor visibility, channel width and sharp bends, inaccurate meanders and over speeding increased its probability of occurrences. Study also found that areas without alternative transport route experienced high incidences of boat accidents compared to areas with road transport exits that suffer exorbitant fair and proximity challenges. There was no statistically significant relationship between the length of the water route and the frequency of incidence (r=0.006; p>0.05). Hence study recommends that Security agencies in charge of maritime routes should be equipped with modern surveillance gadgets, combatant firearm, and warships to enhance maritime security and other response operations.

Stratospheric aerosol size reduction after volcanic eruptions
Authors: Wrana Felix , Niemeier Ulrike , Thomason Larry W. , Wallis Sandra , von Savigny Christian
Published: May 2023

Abstract. The stratospheric aerosol layer plays an important role in the radiative balance of earth primarily through scattering of solar radiation. The magnitude of this effect depends critically on the size distribution of the aerosols. The aerosol layer is in large part fed by volcanic eruptions strong enough to inject gaseous sulfur species into the stratosphere. The evolution of the stratospheric aerosol size after volcanic eruptions is currently one of the biggest uncertainties in stratospheric aerosol science. We retrieved aerosol particle size information from satellite solar occultation measurements from the Stratospheric Aerosol and Gas Experiment III mounted on the International Space Station (SAGE III/ISS) using a robust spectral method. We show that, surprisingly, some volcanic eruptions can lead to a decrease in average aerosol size, like the 2018 Ambae and the 2021 La Soufrière eruptions. In 2019 an intriguing contrast is observed, where the Raikoke eruption (48° N, 153° E) in 2019 led to the more expected stratospheric aerosol size increase, while the Ulawun eruptions (5° S, 151° E), which followed shortly after, again resulted in a reduction of the median radius and absolute mode width values in the lowermost stratosphere. In addition, the Raikoke and Ulawun eruptions were simulated with the aerosol climate model MAECHAM5-HAM. In these model runs, the evolution of the extinction coefficient as well as of the effective radius could be reproduced well for the first 3 months of volcanic activity. However, the long lifetime of the very small aerosol sizes of many months observed in the satellite retrieval data could not be reproduced.
The Modern Ocean Sediment Archive and Inventory of Carbon (MOSAIC): version 2.0

Published: May 2023

Abstract. Marine sediments play a crucial role in the global carbon cycle by acting as the ultimate sink of both terrestrial and marine organic carbon. To understand the spatiotemporal variability in the content, sources and dynamics of organic carbon in marine sediments, a curated and harmonized database of organic carbon and associated parameters is needed, which has prompted the development of the Modern Ocean Sediment Archive and Inventory of Carbon (MOSAIC) database. We present here MOSAIC version 2.0, which has expanded the spatiotemporal coverage of the original database by ~400 %, and now holds data from more than 17000 individual sediment cores from different continental margins on a global scale. Additional variables have also been incorporated into MOSAIC v.2.0 that are crucial to interpret the distribution of the quantity, origin and age of organic carbon in marine sediments globally. Sedimentological parameters (e.g., grain size fractions, mineral surface area) help understand the effect of hydrodynamic sorting and mineral protection in the distribution of organic carbon, while molecular biomarker signatures (e.g., lignins phenols, fatty acids, alkanes) can constrain the origin of organic matter with a greater level of specificity. MOSAIC v.2.0 also stores data from analyses performed on specific sediment and molecular fractions, which provide further insight of the processes that affect the degradation and ageing of organic carbon in marine sediments. While data included within MOSAIC is not exhaustive, it is continuously expanding and version control will allow users to benefit from updated versions while ensuring reproducibility of their findings.
Water level fluctuations drive bank instability in a hypertidal estuary
Authors: Gasparotto Andrea , Darby Stephen E. , Leyland Julian , Carling Paul A.
Published: May 2023

Abstract. Hypertidal estuaries are very dynamic environments
characterized by high tidal ranges (> 6 m) that can experience
rapid rates of bank retreat. Whilst a large body of work on the processes,
rates, patterns, and factors driving bank erosion has been undertaken in
fluvial environments, the process mechanics affecting the stability of the
banks with respect to mass failure in hypertidal settings are not well-documented. In this study, the processes and trends leading to bank failure
and consequent retreat in hypertidal estuaries are treated within the
context of the Severn Estuary (UK) by employing a combination of numerical
models and field-based observations. Our results highlight that the periodic
fluctuations in water level associated with the hypertidal environment drive
regular fluctuations in the hydrostatic pressure exerted on the incipient
failure surfaces that range from a confinement pressure of 0 kPa (at low
tide) to ∼ 100 kPa (at high tide). However, the relatively low
transmissivity of the fine-grained banks (that are typical of estuarine
environments) results in low seepage inflow/outflow velocities
(∼ 3 × 10−10 m s−1), such that variations in
positive pore water pressures within the saturated bank are smaller, ranging
between about 10 kPa (at low tide) and ∼ 43 kPa (at high
tides). This imbalance in the resisting (hydrostatic confinement) versus
driving (positive pore water pressures) forces thereby drives a frequent
oscillation of bank stability between stable (at high tide) and unstable
states (at low tide). This transition between stability and instability is
found not only on a semidiurnal basis but also within a longer time frame. In
the spring-to-neap transitional period, banks experience the coexistence of
high degrees of saturation due to the high spring tides and decreasing
confinement pressures favoured by the still moderately high channel water
levels. This transitional period creates conditions when failures are more
likely to occur.
Drought intensity-duration-frequency curves based on deficit in precipitation and streamflow for water resources management
Authors: Cavus Yonca , Stahl Kerstin , Aksoy Hafzullah
Published: May 2023

Abstract. Drought estimates in terms of physically measurable variables such as precipitation deficit or streamflow deficit are key knowledge for an effective water management. How these deficits vary with the drought event severity indicated by commonly used standardized indices is often unclear. Drought characteristics assigned the same value in index are not necessarily the same in different regions, and in different months of the same region. We investigate drought to remove this disadvantage of the index-based drought IDF curves and develop intensity-duration-frequency (IDF) curves in terms of the associated deficit. In order to study the variation of deficits, we use the link between precipitation and streamflow, and the associated indices, standardized precipitation index (SPI) and standardized streamflow index (SSI). More specifically, the analysis relies on frequency analysis combined with the total probability theorem applied to the critical drought severity. The critical drought has varying durations and it is extracted from dry periods. IDF curves in terms of precipitation and streamflow deficits for the most severe drought of each drought duration in each year are then subject to comparison of statistical characteristics of droughts for different return periods. Precipitation and streamflow data from two catchments, the Seyhan River (Turkey) and the Kocher River (Germany) provide examples for two climatically and hydrologically different cases. A comparison of the two cases allows to test a similar method in different hydrological conditions. We found that precipitation and streamflow deficits vary systematically reflecting seasonality and the magnitude of precipitation and streamflow characteristics of the catchments. Deficits change from one month to another at a given station. Higher precipitation deficits were observed in winter months compared to summer months. Additionally, we assessed observed past major droughts experienced in both catchments on the IDF curves which show that the major droughts have return periods at the order of 100 years at short durations. This coincides with the observation in the catchments and shows the applicability of the IDF curves. The IDF curves can be considered a tool for using in a range of specific activities of agriculture, ecology, industry, energy, water supply etc. This is particularly important to end-users and decision-makers to act against the drought quickly and precisely in a more physically understandable manner.
The seasonal origins and ages of water provisioning streams and trees in a tropical montane cloud forest

Published: May 2023

Abstract. Determining the sources of water provisioning streams, soils, and vegetation can provide important insights into the water that sustains critical ecosystem functions now and how those functions may be expected to respond given projected changes in the global hydrologic cycle. We developed multi-year time series of water isotope ratios (δ18O and δ2H) based on twice monthly collections of precipitation, lysimeter, and tree branch xylem waters from a seasonally dry tropical montane cloud forest in the southeastern Andes mountains of Peru. We then used this information to determine indices of the seasonal origins, the young water fractions (Fyw), and the new water fractions (Fnew) of soil, stream, and tree water. There was no evidence for intra-annual variation in the seasonal origins of lysimeter and stream waters, which were predominantly comprised of wet season precipitation, even during the dry seasons. However, branch xylem waters demonstrated an intra-annual shift in seasonal origin: xylem waters were comprised of wet season precipitation during the wet season, and dry season precipitation during the dry season. The young water fractions of lysimeter (< 15 %) and stream (5 %) waters were lower than the young water fraction (37 %) in branch xylem waters. The new water fraction (an indicator of water ≤ 2 weeks old) was estimated to be 12 % for branch xylem waters, while there was no significant evidence for new water in streams. Our results indicate that the source of water for trees in this system varied seasonally, such that recent precipitation may be more immediately taken up by shallow tree roots. In comparison, the source of water for soils and streams did not vary seasonally, such that precipitation may mix and reside in soils and take longer to transit into the stream. Our insights into the seasonal origins and ages of water in soils, streams, and vegetation in this tropical montane cloud forest adds to understanding of the mechanisms that govern the partitioning of water moving through different ecosystems.
Calving front monitoring at sub-seasonal resolution: a deep learning application to Greenland glaciers

Published: May 2023

Abstract. The mass balance of the Greenland ice sheet is strongly influenced by the dynamics of its outlet glaciers. Therefore, it is of paramount importance to accurately and continuously monitor these glaciers, especially the variation of their frontal positions. A temporally comprehensive parameterization of glacier calving is essential to understand dynamic changes and to constrain ice sheet modelling. However, current calving front records are often limited in temporal resolution as they rely on manual delineation, which is laborious and not feasible with the increasing amount of satellite imagery available. In this contribution, we address this problem by applying an automated method to extract calving fronts from optical satellite imagery. The core of this workflow builds on recent advances in the field of deep learning while taking full advantage of multispectral input information. The performance of the method is evaluated using three independent validation datasets. Eventually, we apply the technique to Landsat-8 imagery. We generate 9243 calving front positions across 23 Greenland outlet glaciers from 2013 to 2021. Resulting time series resolve not only long-term and seasonal signals but also sub-seasonal patterns. We discuss the implications for glaciological studies and present a first application analysing the interaction between calving front variation and bedrock topography. Our method and derived results represent an important step towards the development of intelligent processing strategies for glacier monitoring, opening up new possibilities for studying and modelling the dynamics of Greenland outlet glaciers. Thus, these also contribute to advance the construction of a digital twin of the Greenland ice sheet, which will improve our understanding of its evolution and role within the Earth's climate system.

Published: May 2023

Introduction: Cardiovascular disease (CVD) has become the leading cause of mortality in the world, more so in the perimenopausal age group due to decreased levels of estrogen and diminished ovarian function because of ageing.Objective:To find out the magnitude of CVD risk amongperimenopausal women residing in rural Bengal and its associated determinants.Method: A cross-sectional study was conducted in a rural area of Barasat block I during April-July 2021 on 150 peri-menopausal women selected by cluster sampling. A pre-designed pretested questionnaire was used for data collection and a 10-year probability of CVD risk was assessed using Framingham Risk Score. Logistic regression analysis was done to find out the associated factors.Results: Intermediate & high CVDrisk was present in 28 (18.7%) and 63 (42%) participants respectively. Among 150 participants, 62% were hypertensive, 44.7% were diabetic, 51.3% with borderline high total cholesterol and 76% had low HDL cholesterol. Factors significantly associated with intermediate to high CVD risk were high mental stress [AOR=6.96, 95%CI=2.17-22.31], family history of chronic illness [AOR=14.46, 95% CI=4.26-49.06] and presence of chronic morbidities [AOR=6.84, 95%CI=1.93-24.22].Conclusion: A significant proportion of perimenopausal women were at risk of developing CVD. Thus, awareness campaigns in the community would help in empowering women in maintaining their health through regular screening and timely intervention when deemed necessary.

Introduction: Improvement of maternal health care services will not only put a positive impact on
maternal health, but also on the health of the new born. Objectives: This study was conducted to estimate
the proportion of eligible beneficiaries who received the benefits provided by the scheme, to identify the
barriers faced by the beneficiaries and health providers related to the scheme and to find possible solutions
to overcome the barriers found as suggested by them in a block of West Bengal. Method: A cross-sectional
study with sequential explanatory mixed-method approach was conducted in a block of West Bengal from
January-December 2021. Quantitative data was collected from the digital portal of PMMVY. All beneficiaries
who had their Last Menstrual Period (LMP) on and after 1st March 2020 up to 31st December 2020 were
included. To identify the barriers faced and suggest possible solutions, Focused Group Discussions (FGDs)
were held with the beneficiaries, ANMs and ASHAs and Key-Informant Interviews (KIIs) with the Block
Medical Officer and Data Entry Operator. Data were analyzed using SPSS version 25.0. Descriptive statistics
were used to summarize quantitative data while qualitative data were analyzed in the form of themes, codes
and verbatim. Results: Total eligible beneficiaries for the three installments were 1066, 917 and 708
respectively. About 95.5% beneficiaries received the first installment, 93.0% received the second and 98.3%
had received the third installment. The broad themes [codes] generated from the FGDs were challenges
during antenatal care [ANC refused, home visit preferred, home ANC difficult, lockdown], challenges related
to the PMMVY scheme [documents unavailable, incomplete forms, payment issues], possible solutions
[prepare pre-requisites beforehand, provide cash]. Widely two main themes emerged from the KIIs: Form
related issues and Payment issues. Conclusion: Coverage of PMMVY scheme in the block was satisfactory.
However, speeding the payment process and stricter monitoring of the scheme is required.

Prioritisation of research activities, community and collegial engagement, and the capacity to pivot when faced with challenges of changing work contexts shaped their identity development. Findings revealed that diverse engagements enhance researchers’ career advancement in a post Covid-19 environment.
La cuestión de la migración y el desarrollo de cara al siglo XXI: imperialismo y exportación de fuerza de trabajo
Authors: Delgado Wise Raúl
Published: May 2023

Se argumenta que la relación entre migración y desarrollo en el capitalismo e imperialismo contemporáneos tiene como basamento la emergencia de una nueva división internacional del trabajo, cuyo eje es la exportación de fuerza de trabajo. Esta exportación opera por dos vías complementarias: una indirecta, mediante las plantas de ensamblaje instaladas en los países periféricos y otra directa, a través de la migración laboral. Con la profunda reestructuración que experimentan los sistemas de innovación en la actualidad, la exportación de fuerza de trabajo adquiere una connotación más amplia al incorporar fuerza de trabajo cualificada y altamente cualificada proveniente de los países periféricos.
Implicaciones de los cierres fronterizos por la COVID-19 para la atención de los migrantes por parte de los gobiernos locales en México
Authors: Vázquez Meneley Sergio Ismael
Published: May 2023

Después de declararse la pandemia COVID-19, el cierre de fronteras fue una de las medidas que varios gobiernos del mundo adoptaron para evitar la propagación de contagios, sin contar con evidencia suficiente al respecto. Las consecuencias de estos cierres tuvieron repercusiones en la vulnerabilidad de los migrantes en tránsito por México atrapados a lo largo del país. En este contexto, los gobiernos locales y fronterizos –por su cercanía y proximidad con los procesos migratorios presentes en el territorio– se convirtieron en piezas clave para proveer servicios y proteger los derechos humanos de los migrantes a través de diferentes acciones. Por ello, en este artículo se analiza el papel de los gobiernos locales y la migración.

Este artículo analiza el papel del nexo Humanitarismo-Desarrollo (NHD) en el ámbito de la gestión de la movilidad de las personas en búsqueda de protección en Europa. Para ello partiremos de un análisis histórico de la configuración del nexo migración-desarrollo y su paso al NHD en el marco de las políticas migratorias y de asilo europeas. A continuación, partimos del caso de Ucrania para analizar cómo opera el humanitarismo como una primera etapa del NHD en el ámbito del refugio en Europa y en España en el ámbito de la acogida de la población ucraniana desplazada tras la invasión rusa en febrero de 2022. Esto nos permite comprender las lógicas políticas, simbólicas y culturales que orientan la construcción humanitaria de la gestión del refugio.

Regression problems among multiple responses and predictors have been widely employed in many applications, such as biomedical sciences and economics. In this paper, we focus on statistical inference for the unknown coefficient matrix in high-dimensional multi-task learning problems. The new statistic is constructed in a row-wise manner based on a two-step projection technique, which improves the inference efficiency by removing the impacts of important signals. Based on the established asymptotic normality for the proposed two-step projection estimator (TPE), we generate corresponding confidence intervals for all components of the unknown coefficient matrix. The performance of the proposed method is presented through simulation studies and a real data analysis.

The method of analysis of secondary data obtained from open sources of the Committee for Quality Assurance in Education and Science, the Center for the Bologna Process and Academic Mobility, the Information and Analytical Center under the Ministry of Education and Science of the Republic of Kazakhstan was used. Content analysis of legislation, strategic and program documents, national reports, speeches was also carried out. In addition, a mixed research method was used as an expert survey (758 respondents) and an expert interview (14 people).The originality / value of the research lies in conducting a study based on the opinions of employees and teachers of Kazakhstani universities to determine the level of their perception of preventive control and accreditation.Findings. As a result of the analysis of the assessment of preventive control and accreditation and the perception of universities, more positive assessment of accreditation than of preventive control was revealed. The survey results proved that despite the rejection of state certification, the elements and approach in preventive control remain «bureaucratic» and «limiting the autonomy of universities».Considering the positive perception of independent accreditation by the academic community, today the question is brewing as to whether it is already relevant to use these two tools in parallel with duplicate goals (achieving quality, improving quality) in quality assurance.
