Identitats literàries que milloren les reals. Mimesi i historiografia: lligams entre cavalleria literària, historiografia i espais en la (de)construcció de la identitat en les lletres catalanes medievals
Authors: Martines Vicent
Published: August 2023

Summary: We analyze how through some chronicles that describe the deeds of kings as examples of knights and rulers, literary mimesis becomes an essential tool to showcase models that can be utilized for the official image of the Crown. We use the four great Catalan chronicles (the first three in particular) and other historiographical accounts which use a great deal of literary mimesis as well as cultural and literary referents (classical tradition, matter of Britain), as well as the Cançó de la croada contra els albigesos. We pay attention to the view offered in them of the Battle of Muret. We also pay attention to Jaume’s conquests (a consequence of Muret) as viewed by the Muslims. We also analyze the consequences of this battle for England, such as the (xenophobic) suspicion that the English barons felt towards the newcomers, members of the retinue of Queen Eleanor of Provence, the daughter of Ramon Berenguer IV of Provence and therefore Jaume I’s niece. Eleanor finally retired to the Abby of Amesbury, which in turn became a place where identities formed and where, now that the queen was there residing, Arthurian motifs could be made credible: it is the place where Queen Genevieve retired after the Battle of Camlaan, which took place (in literature) on the fields of Salisbury, close to Amesbury. In sum, we analyze classical tradition, matter of Britain, victories and defeats, chronicles, chivalries, etc., all of them relevant topics for acquiring identity and that imply transferences: literature and history, mimesis that has an influence on reality. Keywords: Identity, mimesis, chronicles, Croada contra els albigesos, Battle of Muret, Elionor de Provença, Arthurian cycle, spaces and identity
Els clubs de lectura a les biblioteques públiques de Catalunya, el País Valencià i les Illes Balears
Authors: Baldaquí Josep M.
Published: August 2023

Summary: Book clubs – a phenomenon that comes from afar – have experienced remarkable quantitative and qualitative expansion lately. This paper aims at describing the deployment of book clubs in Catalonia, the Valencian Country and the Balearic Islands for the first time. The research is based on a survey carried out among the public libraries of the three territories and intends to describe the main features of this phenomenon, including the linguistic uses in this particular context. The results show a different degree of deployment of book clubs, which is a more ingrained and diversified phenomenon in Catalonia than in the other territories. The comparative study of the characteristics of book clubs allows us to suggest strategies to facilitate the expansion of book clubs in the Valencian Country and the Balearic Islands. Keywords: Book clubs, Catalan language, public libraries, description, comparative study, linguistic usage
La literatura a Twitter. Estudi del cas #Diadelllibre
Authors: Francés Díez M. Àngels
Published: August 2023

Summary: In recent years, Twitter has gone from being a social network with rather banal content to a powerful channel for the dissemination of information and content promotion. For this reason, in this paper we present the study of some of the data that Séntisis extracted from Twitter about the Sant Jordi Festival (World Book Day & Rose) 2017, which shows a sort of map of place of our book industry. We also offer some ideas about its potential as a space for experimentation with literature and reading, in accordance with the new models of cultural practice proposed by Jenkins (2003 and 2008, with the concept of transmedia and that of participatory culture, respectively) and Scolari (2016, with the idea of the translector), among others.

Published: August 2023

Among the most typical feed ingredients for shrimp, plants represent a low-cost source in substituting for traditional high-cost feed ingredients. Extrusion is a common grains processing technique to make plant nutrients available and more digestible to animal. Different levels (15, 30, 45, and 60%) of extruded low-quality chickpea meal were included in a formulated diet for the juvenile shrimp Litopenaeus vannamei cultured in a closed system for 75 days. The growth of shrimp fed with the tested diets was similar to the control group (P > 0.05). We concluded that the use of extruded cull chickpea meal is a potential food alternative to replace fishmeal effectively in diets for L. vannamei.

The aim of the study was to investigate the dynamics of clinical and laboratory parameters of inflammatory disease activity and cytokines in patients with rheumatoid arthritis (RA) against the background of olokizumab (OKZ) treatment.Materials and methods. Ten patients with a reliable diagnosis of RA were examined: patients’ age was 46.00 (30.00; 60.00) years, duration of disease was 9.0 (3.0; 12,0) years. All patients had moderate to high disease activity: DAS28-ESR (Disease Activity Score 28 with Erythrocyte Sedimentation Rate) – 513 (4.34; 5,80); CDAI (Clinical Disease Activity Index) – 30.00 (24.00; 35.00); SDAI (Simplified Disease Activity Index) – 31.86 (24.36; 38.59). All patients were treated with OKZ at a dose of 64 mg subcutaneously every 4 weeks on the background of therapy with methotrexate, leflunomide, nonsteroidal anti-inflammatory drugs, and glucocorticoids. Observations were performed before treatment and after 3, 6 months of therapy. Serum levels of 15 cytokines: interleukin (IL) 1β, IL-4, IL-6, tumor necrosis factor α (TNF-α), interferon (INF) γ, IL-10, IL-17A, IL-17F, IL-21, IL-22, IL-23, IL-25, IL-31, IL-33, sCD40L, – were examined using multiplex xMAR technology.Results. After 3 and 6 months of OKZ therapy, there was a significant decrease in DAS28-ESR of 3.53 (2.83; 4.26) and 3.48 (2.8; 4.10); CDAI – 11.00 (6.0; 16.00) and 10.0 (5.0; 15.0); SDAI – 10.0 (5.0; 15.0) and 10.17 (7.02; 15.02); C-reactive protein (CRP) concentrations (initial – 14.30 (7.00; 24.70) mg/l, after 3 months – 0.70 (0.40; 0.90) mg/l and after 6 months – 0.65 (0.20; 3.00) mg/l). After 3 months of treatment we found an increase in IL-6 concentration (initial – 1.89 (1.61; 2.33) pg/ml and 89.98 (35.09; 165.84) pg/ml; p<0.01), after 6 months – its level decreased to 44.88 (5.25; 80.90) pg/ml without reaching, however, the initial values (p<0.05). Against the background of OCZ, after 3 months of treatment there was an increase in IL-25 concentration (p<0.01), and after 6 months of therapy – TNF-α (p<0.05).Conclusion. The use of OKZ leads to an increase in the concentration of total IL-6 in the blood serum of RA patients, while the clinical and laboratory activity of the disease decreases.

Theological Rigidity Against Covid-19 Vaccines Among Rural Christian Learners in Gutu, Zimbabwe
Authors: Chidarikire Munyaradzi
Published: August 2023

This article explores theological rigidity and misconceptions against solutions to increase COVID-19 vaccination among rural learners in Zimbabwe. This qualitative study is anchored on socio-cultural theory by Levi Vygotsky. An interpretive paradigm embedded in a case study design was used to explore the concepts. We used a purposive sampling technique to select nineteen knowledge rich rural Christians drawn from Pentecostals, African initiated Traditional Churches and Evangelicals denominations. In-depth interviews were conducted with the selected informants. Two focus group discussions (FGDs) were administered with participants drawn from each of the three denomination categories, giving a total of six FGDs. Data generated through focus group discussions were analyzed through thematic content analysis. We found that a significant number of rural learners in Zimbabwe have not been vaccinated due to a myriad of reasons. These include their rigid theological beliefs, cultural resistance and political skepticism. Consequently, the paper recommends that there is need for the Government, Church organizations and other stakeholders to collectively engage each other and find solutions to increase the uptake of COVID-19 vaccines among rural learners.

Authors: Fatemi Sayed Ahmad Zamir , Zgham Wahidullah , Shirzad Safiullah , Serat Zainullah
Published: August 2023

Solar energy stands as a paramount clean, abundant, and renewable power source holding remarkable potential to address our escalating energy needs. Among its crucial utilization methods, solar water heating systems integrating flat plate collectors (FPCs) emerge as vital contributors in harnessing and converting solar energy into utilizable heat. This study delves into the realm of FPCs' theoretical efficiency assessment, employing mathematical models and factoring regional weather conditions to meticulously evaluate the efficiency of single-glaze and double-glaze collector variants. The outcomes spotlight the single glaze collector's efficiency at 0.669 and the double glaze collector at 0.713, underscoring the discernible performance gap. In a landscape where industries, hospitals, residences in Kandahar, and comparable settings extensively depend on hot water, often derived from fossil fuel-driven heating, this research's implications hold particular relevance. By transitioning towards solar water heating, this study not only underscores a concrete method to curtail carbon emissions but also to significantly reduce energy expenses linked with conventional heating techniques. The findings beckon a departure from the status quo, emphasizing that cleaner energy options are attainable, even for regions demanding hot water requirements. As society navigates complex decisions concerning energy sourcing, embracing solar water heating stands as an auspicious stride towards a sustainable future, beckoning us to collectively embark on a path of energy-conscious choices for the greater good of our planet and the generations that will inhabit it.

Analysis of Mental Health Status Model of Students in Higher Vocational Colleges based on Potential Profile
Authors:   Weihai Ocean Vocational College, Yuwei BIAN
Published: August 2023

In order to strengthen the level of vocational college students' mental health research, and to understand the overall situation of students' mental health, this study investigated 550 vocational college students. The study mainly used the SCL-90 measurement tool to conduct a mental health test and establish the potential profile model. Through the analysis of SPSS and MPLUS, the study found that the mental health level of students in vocational college was relatively good, with higher levels of mental health than the national norm, but with serious polarization, i. e. higher scores for students with psychological abnormalities. In each dimension of the test, it was found that the dimensions with more positive factors were more mainly focused on: obsessive-compulsive symptoms, interpersonal sensitivity and depression. Through the analysis of the potential profile model, it was found that the mental health level of students could be divided into three categories: “Mildly problematic group”, “Potentially problematic group” and“Highly Problematic Group”, the mental health level of the students mainly concentrated in the“Minor problem group”. The differences between the groups are obvious, and students' mental health levels are mainly concentrated in the “mild problem group”. Therefore, in the mental health work of higher vocational colleges, it is necessary to carry out daily propaganda and education to improve overall mental health literacy. At the same time, we need to strengthen the supervision of key students, carry out tracking analysis, establish personal psychological files, and promote home-school interaction.

Since the mid-20th century, the global population has increased dramatically, and human activities have encroached on a large number of natural spaces, resulting in drastic land use/cover changes. A series of ecological security problems took place as a result, such as climate change, environmental pollution, and resource shortage, posing severe challenges to global sustainable development. As the largest and the most populous developing country in the world, China’s land use/cover change is more prominent compared to that of other countries. Therefore, the comprehensive analysis of land use/cover change in China is of great significance in dealing with global change, repairing ecological damage, and alleviating the contradiction between man and land. Based on the literature of land use/cover change in China from 2012 to 2022 in the Web of Science database, this paper analyzes the research status, characteristics, regional differences, and evolution law of land use/cover change in China by using Bibliometrix and Biblioshiny software packages. The results show that: (1) The annual number of papers published in the field of land use/cover change in China is steadily increasing. However, the average annual citation amount fluctuates but shows a general downward trend; (2) From 2012 to 2022, a total of 73, 157 authors published articles in the field of land use/cover change in China, among whom Zhang Yili, Liu Yansui, and Li Xiubin ranked the top three; (3) 153 countries or regions in the world have literature output in the field of land use/cover change in China, and the top three output countries are China, the United States and Germany. Among research, papers from China and the United States has played an important role in international cooperation in the field of land use/cover change in China; (4) The key words of land use/cover change research in China can be divided into three categories: the first category focuses on the research of driving factors/factors of land use/ cover change in China; The second category focuses on the models and technical methods of land use/cover change research in China; The third category emphasizes the role of policies and government management; (5) During the ten years from 2012 to 2022, the theme of land use/cover change in China changed little, mainly focusing on climate change and management.
Concussion in sport – What do we know, and what’s next?
Authors: Matthews Christopher , Watson Penny , Dening Tom , Varley Ian , Hunter Angus , Malcolm Dominic , Flores Debi , AlHashmi Reem
Published: August 2023

This paper presents shortened versions of talks given at a symposium about concussion in sport. The piece is designed, in similar lines as the event, to help communicate knowledge and ideas between academics in multiple disciplines, communities of practice and to develop public and patient involvement. The seven short essays are presented in the style of a conference proceedings paper. Each author presents their own focus, with one paper drawing on lived experiences and activism, three taking a biomedical approach and the remaining three drawing on social scientific analysis and literature. We have developed this paper to provide readers with a concise, but not complete, understanding of different topics related to concussion and brain injuries in sport. The limitations of space means that the authors have had to reduce the complexity of some ongoing debates on the topic. The final section is based on the comments and discussions that happened during and after the symposium. It offers some important takeaways and encourages scholars working in this area to prioritize multi-disciplinary research, and highlights the importance of centering the experiences and lives of those people affected by concussions and neurological disorders in the development and delivery of future work. It is hoped that communicating ideas in this way will encourage such ways of thinking as a means of tackling the complex set of problems that face those involved in sports where repeated forceful impact is a normalized 'part of the game'.

Authors: Santos José Glauber Cavalcante dos , Oliveira Andreia Arruda de
Published: August 2023

Este estudo tem como objetivo examinar a relação entre os custos e a qualidade dos serviços prestados pelas distribuidoras de energia elétrica no Brasil listadas na Brasil Bolsa Balcão (B3). A amostra é formada por 21 empresas com dados referentes ao período 2015-2019. O custo foi mensurado a partir do valor reconhecido pelas empresas como custo do serviço prestado para cada exercício social na Demonstração do Resultado do Exercício (DRE). Como medidas para a qualidade dos serviços prestados, adotou se: (i) Índice ANEEL de Satisfação do Consumidor (IASC) – medida de qualidade externa; e (ii) Duração Equivalente de Interrupção por Unidade Consumidora (DEC) e Frequência Equivalente de Interrupção por Unidade Consumidora (FEC) – medidas de qualidade internas. Como medidas de controle, foram testadas a idade, gastos com Pesquisa & Desenvolvimento, rentabilidade, governança corporativa e controle. Foram feitas estimações com regressões lineares em painel balanceado e regressão quantílica. Os resultados mostram que o custo desses serviços absorve, na média, mais de 80% do faturamento. O custo reconhecido no período relaciona-se positivamente com a qualidade dos serviços ofertados. A evidência mostra que maiores valores de custo explicam aumentos no IASC e reduções de DEC e FEC, sinalizando o efeito favorável do custo na qualidade nesse setor. As medidas de controle também explicam variações da qualidade. Conclui-se que o custo pode ter o papel de variável estratégica importante na prestação de serviço dentro do setor de energia elétrica no Brasil.
Do STEM teachers have the potential to become leaders in online education?
Authors: Chiu Hsin-Yi , Liu Chia-ju
Published: August 2023

STEM teachers would need to be familiar with the use of technology in the classroom and in fact they appeared to find online teaching very simple and natural. We have an opportunity to get a clearer idea of the challenges that STEM teachers faced as they transitioned from FTF to the online teaching precipitated by the COVID-19 epidemic, how well they were able to respond, and what changes were implemented. A qualitative design, with a case study approach, was used to find out how well they responded and what necessary changes had needed to be implemented. Nine STEM teachers took part in this study and the interview questions used by Sintema were modified and used as the main research tool (2020). Interviews were carried out in three steps. The data were divided into four stages: "#1 preparation time," "#2 early phase," "#3 late phase," and "#4 resumption of face-to-face teaching." In this study all the changes in method and characteristics elicited by online teaching of STEM were compared with those in use before the advent of large-scale online teaching. We uncovered many of the difficulties and concerns experienced by teachers who were under pressure to make the online courses significant in a short period of time. The study also discovered that the challenges that STEM teachers face are quite complex and diverse, and that STEM teachers' online teaching experiences can indeed become an important reference for teachers of other disciplines.
How to explain the rationale of putting research into practice? A book review on Visual-Spatial Ability in STEM Education Transforming Research into Practice
Authors: Baskota Prateet
Published: August 2023

The book is crucial for exposing educational settings to research academics since it is visually appealing. It explains how spatial ability is tested and improved and explores the research procedures and skills utilized in educational settings. It concentrates on the problematic meta-analytic review and addresses two distinct cross-questions, including how large gender disparities in spatial ability are and where gender differences in spatial ability are first observed. The book purposefully covers a wide range of viewpoints, including those from cognitive psychology, educational psychology, science, technology, engineering, mathematics, computer science and information technology. It also addresses human growth. This book gives ideas about the early life span of visuospatial working memory development, along with the impact. As a reader, I found that these abilities have on academic learning with a biological explanation for the observed gender differences that seems to be a contribution to brain development that was shared through the book by the author for readers.
Bacterioplankton dark CO2 fixation in oligotrophic waters
Authors: Alothman Afrah , López-Sandoval Daffne , Duarte Carlos M. , Agustí Susana
Published: August 2023

Abstract. Dark CO2 fixation by bacteria is believed to be particularly important
in oligotrophic ecosystems. However, only a few studies have characterized
the role of bacterial dissolved inorganic carbon (DIC) fixation in global
carbon dynamics. Therefore, this study quantified the primary production
(PP), total bacteria dark CO2 fixation (TBDIC fixation), and
heterotrophic bacterial production (HBP) in the warm and oligotrophic Red
Sea using stable-isotope labeling and cavity ring-down spectroscopy
(13C–CRDS). Additionally, we assessed the contribution of bacterial DIC
fixation (TBDIC %) relative to the total DIC fixation
(totalDIC fixation). Our study demonstrated that TBDIC fixation increased the totalDIC fixation from 2.03 to 60.45 µg C L−1 d−1 within the photic zone, contributing 13.18 % to 71.68 % with an average value of 33.95 ± 0.02 % of the
photic layer totalDIC fixation. The highest TBDIC fixation values were measured at the surface and deep (400 m) water with
an average value of 5.23 ± 0.45 and
4.95 ± 1.33 µg C L−1 d−1, respectively. These
findings suggest that the non-photosynthetic processes such as anaplerotic
DIC reactions and chemoautotrophic CO2 fixation extended to the entire
oxygenated water column. On the other hand, the percent of TBDIC
contribution to totalDIC fixation increased as primary production
decreased (R2=0.45, p<0.0001), suggesting the relevance
of increased dark DIC fixation when photosynthetic production was low or
absent, as observed in other systems. Therefore, when estimating the total
carbon dioxide production in the ocean, dark DIC fixation must also be
accounted for as a crucial component of the carbon dioxide flux in addition to
photosynthesis.
Investigating the impact of HARMONIE-WINS50 (cy43) and LOTOS-EUROS (v2.2.002) coupling on NO2 concentrations in The Netherlands
Authors: Yarce Botero Andres , van Weele Michiel , Segers Arjo , Siebesma Pier , Eskes Henk
Published: August 2023

Abstract. Meteorological fields calculated by Numerical Weather Prediction (NWP) Models drive offline Chemical Trans port Models (CTM) to solve the transport, chemical reactions, and atmospheric interaction over the geographical domain of interest. In this way, forecasts and (re-)analyses provided by NWP can be used for air quality forecasting, climate modeling, and environmental studies. The more precise the meteorological input data represents the atmospheric dynamics, the better the CTM represents pollutant transport, mixing, and the subsequent impact on surface air quality. HARMONIE (HIRLAM ALADIN Research on Mesoscale Operational NWP in Euromed) is a state-of-the-art non-hydrostatic NWP community model used at several European weather agencies to forecast weather at the local and/or regional scale. In this work, the HARMONIE WINS50 (cycle 43 cy43) reanalysis data set at a resolution of 0.025° × 0.025° covering an area surrounding the North Sea for the years 2019–2021 was offline coupled to the state-of-the-art model LOTOS-EUROS (v2.2.002), which is CTM that is one of the members of the Copernicus Atmosphere Monitoring Service (CAMS) ensemble of CTMs that is used to produce operational air quality forecasts over Europe and at a higher resolution also over the Netherlands. The impact on simulated NO2 concentrations of using meteorological fields from HARMONIE in LOTOS-EUROS compared to the use of fields from ECMWF (here used at 0.7° ×0.7°) is evaluated against ground-level sensors and TROPOMI tropospheric NO2 vertical columns. Furthermore, the difference between crucial meteorological input parameters such as the boundary layer height and the vertical diffusion coefficient between the hydrostatic (ECMWF) and non-hydrostatic (HARMONIE) model fields is studied, and the vertical profiles of temperature, humidity, and wind are evaluated against meteorological vertical profile observations at Cabauw in The Netherlands. The results of these first evaluations of the LOTOS-EUROS model performance in both configurations are used to investigate current uncertainties in air quality forecasting in relation to driving meteorological parameters and to assess the potential for improvements in high-resolution air quality forecasting episodes based on the HARMONIE NWP model.

Abstract. The pristine atmosphere of the southwest Indian Ocean (SWIO) basin underwent significant perturbations during the 2020 austral summer. This study documents the complex variability of aerosols and carbon monoxide (CO) over this remote oceanic region and identifies the processes governing it in the upper troposphere – lower stratosphere (UT-LS). Aerosol profiles exhibit a multi-layer structure in the tropical UT-LS in January and February 2020. The numerical models (FLEXPART and MIMOSA) showed that the modulation of the aerosol content in the lower stratosphere is due to the intense and persistent stratospheric aerosol smoke layer generated during the 2019–20 extreme Australian bushfire events. One part of this stratospheric aerosol smoke layer was advected zonally by the prevailing easterly winds and its passage over Reunion was recorded by increased aerosol extinction profiles on 27th and 28th January. The analysis of the advected potential vorticity highlights an isentropic transport of air masses containing Australian biomass burning aerosol from extra-tropical latitudes to Reunion at the 400 K isentropic level, on 28th January. Interestingly, our results show that the biomass burning activity in eastern Africa, weak during this season, contributed to modulate (up to 90 %) the vertical distribution of CO and aerosols in the upper troposphere over the SWIO basin. The simultaneous presence of African and Australian aerosols smoke layers has been recorded by ground-based observations at Reunion. This study highlights for the first time the influence of the African emissions from biomass burning to the CO and aerosols distribution in the upper troposphere over the SWIO basin during the convective season. The results show that besides PyroCb -driven injection of biomass burning products to the stratosphere, an alternative pathway may exist during the regular deep-convection season in the tropics.

Abstract. Terrestrial water storage (TWS) includes all forms of water stored on and below the land surface, and is a key determinant of global water and energy budgets. However, TWS data from measurements by the Gravity Recovery and Climate Experiment (GRACE) satellite mission are only available from 2002, limiting global and regional understanding of the long-term trends and variabilities in the terrestrial water cycle under climate change. This study presents long-term (i.e., 1940–2022) and high-resolution (i.e., 0.25°) monthly time series of TWS anomalies over the global land surface. The reconstruction is achieved by using a set of machine learning models with a large number of predictors, including climatic and hydrological variables, land use/land cover data, and vegetation indicators (e.g., leaf area index). The outcome, machine learning-reconstructed TWS estimates (i.e., GTWS-MLrec), fits well with the GRACE/GRACE-FO measurements, showing high correlation coefficients and low biases in the GRACE era. We also evaluate GTWS-MLrec with other independent products such as the land-ocean mass budget, atmospheric and terrestrial water budget in 341 large river basins, and streamflow measurements at 10,168 gauges. The results show that our proposed GTWS-MLrec performs overall as well as or is more reliable than previous TWS datasets. Moreover, our reconstructions successfully reproduce the consequences of climate variability, such as strong El Niño events. GTWS-MLrec dataset consists of three reconstructions based on JPL, CSR and GSFC mascons, three detrended and de-seasonalized reconstructions, and six global average TWS series over land areas, both with and without Greenland and Antarctica. Along with its extensive attributes, GTWS_MLrec can support a wide range of geoscience applications such as better understanding the global water budget, constraining and evaluating hydrological models, climate-carbon coupling, and water resources management. GTWS-MLrec is available on Zenodo through https://zenodo.org/record/8187432 (Yin et al., 2023c).

Abstract. In the boreal forest, winter temperatures are projected to increase substantially by 2100, resulting in a reduction in snow cover thickness and duration. These changes are likely to affect hydrological processes such as snowmelt, the soil thermal regime, and snow metamorphism. The exact impact of future changes is difficult to pinpoint in the boreal forest, due to its complex structure, and the fact that snow dynamics under the canopy are very different from those in the gaps. Although the effects of warmer winters on snow-related processes are well documented, their interactions to influence the spring runoff in evergreen forest remain poorly understood. In this observational study, we assess the influence of a low-snow and warm winter on snowmelt dynamics, soil freezing, snowpack properties, and spring streamflow in a humid and discontinuous boreal catchment of eastern Canada (47.29° N, 71.17° W, 850 m ASL). We monitored the soil and snow thermal regimes and sampled physical properties of the snowpack under the canopy and in two forest gaps during an exceptionally low-snow and warm winter, plausibly representative of future winters, and during a winter with conditions close to normal. We observe that snowmelt was earlier but slower, top soil layers were cooler, and gradient metamorphism was enhanced during the low-snow and warm winter. However, we observe that snowmelt duration increased in forest gaps, that soil freezing was enhanced only under the canopy, and that snow permeability increased more strongly under the canopy than in either gap. Overall, we observe that the spring streamflow discharge was significantly reduced in the warmest year due to a slower melt and low precipitation in April and May. Our results, based solely on field observations, highlight the complex effects of warmer winters on snow hydrology in discontinuous boreal forests.

Стаття присвячена дослідженню особливостей психологічного насильства, як форми домашнього насильства. Кризові соціально-економічні явища притаманні для українського суспільства, особливо в період дії воєнного стану, призвели до зменшення фінансування соціальної сфери, що, серед іншого, потягло за собою негативну реакцію у вигляді деформації соціалізації нових поколінь. Одним із негативних наслідків впливу кризових соціально- економічних явищ на сім’ю є щорічне зростання проявів домашнього насильства. Зазначено, що ця проблема стосується не тільки фізичного, але й психологічного насильства. Психологічне насильство, як вид домашнього насильства є найбільш поширеним на теренах нашої держави протягом останніх років. Вказано, що психологічне насильство – це словесні образи, погрози, приниження, переслідування, залякування, певні діяння, спрямовані на обмеження волевиявлення особи, контроль у репродуктивній сфері, якщо такі дії або бездіяльність викликали у постраждалої особи побоювання за свою безпеку чи безпеку третіх осіб, спричинили емоційну невпевненість, нездатність захистити себе або завдали шкоди психічному здоров’ю особи. Найчастіше психологічне насильство вчиняється у спосіб словесних образ, погроз, приниження, переслідування, залякування. При цьому, найбільш поширеним способом вираження погроз є її усне або вербальне вираження при особистому контакті суб’єкта домашнього насильства та потерпілої особи. Зроблено висновок, що враховуючи труднощі, які виникають під час доказування факту застосування психологічного насильства, варто застосовувати весь комплекс правових заходів, серед яких важливе місце займає висновок судово-психологічної експертизи, який поряд з іншими доказами, є необхідним для встановлення факту вчинення саме психологічного насильства.

Homelessness was already a well-known risk factor contributing to premature death, morbidity, mental illness, and substance use disorder. The coronavirus disease for 2019 (COVID-19) pandemic has amplified disparities in Canada’s public health system, disproportionately impacting people experiencing homelessness. The present study aimed to investigate the impact of the COVID-19 pandemic on the homelessness situation in Canada from community stakeholders’ perceptions. The study used qualitative research approaches underlain by focused ethnography tenets. The sample includes 200 service providers from 28 communities across Canada (at least one site in each province and territory) to participate in virtual focus groups. Data analysis followed a four-step ethnographic approach for thematic analysis in qualitative research. Six main themes emerged: (a) system changes precipitated by the COVID-19 pandemic; (b) personal changes in life circumstances; (c) previous strategies no longer working; (e) opportunities; (d) some things getting better; (f) an overall increase in first time and recurrent homelessness in Canada. The study findings underscored mechanisms required to help ‘tip the scale’ in affording people experiencing homelessness the opportunity to avoid or exit homelessness.

Devido ao clima frio e altitude, identificar as tendências dinâmicas da vegetação e os principais fatores que contribuem para mudanças de cobertura vegetal em áreas de Campos de Altitude é essencial para entender alterações climáticas em regiões montanhosas. Imagens Landsat-8 OLI e Landsat-1 MSS de 1973 a 2022 da Morraria do Urucum e Serra do Amolar foram pré-processadas na plataforma de nuvem GEE e QGIS. O método de reamostragem por pixel na escala de valores definidos para vegetação Campos de Altitude foi empregado para evidenciar mudanças da cobertura da vegetação e suas dinâmicas através do índice NDVI. Em ambas as áreas de estudo foi verificada tendência contínua de redução significativa da vegetação de campos de altitude em 50 anos. O decréscimo médio foi de 49% para Urucum (menos 2.164 hectares) e 43% para o Amolar (menos 3.959 hectares). O uso do GEE para obter dados de sensoriamento remoto combinado com a análise de imagens temporais oferece o potencial de perceber rapidamente tendências de mudança de cobertura da vegetação em grande e pequena escala
'Māori tourism and a post-growth economy'
Authors:   Constance University of Applied Sciences, Thimm Tatjana
Published: August 2023

A post-growth economy is a comparatively new paradigm in the tourism discourse. The aim of this article is to find out the commonalities between this concept and Māori tourism and in which way the latter can contribute to a post-growth economy. A qualitative mixed method approach, including in-depth-interviews, participant observation, and secondary analysis is applied. The results show that there is a lot of overlap between Māori tourism and a post-growth economy. Differences are visible, as well, regarding the value approach of Māori tourism and the indicator approach of a post-growth economy. Especially the social innovation created in Aotearoa New Zealand at the instigation of Māori groups of granting legal personhood to parts of nature may serve as a driver for a form of tourism that is in line with the idea of a post-growth economy.

Glucagon-like peptide-1 is an isulin-like peptide hormone from the incretin family. The most popular pharmaceutical analogue of GLP-1 at the moment is liraglutide. GLP-1 receptors are localized in many areas of the brain responsible for the regulation of metabolic processes and eating behavior and in specific areas of the pancreas, heart, blood vessels, immune system, skin and adipose tissue, gastrointestinal tract and kidneys. We can definitely say that the effect of liraglutide extends to all tissues equipped with GLP-1 receptors, while the effect of the drug on the cardiovascular system, immune system, kidneys and gastrointestinal tract is still being studied. Also interesting is the possible effect of liraglutide on the liver, as an organ directly related to lipid and carbohydrate metabolism. In this article, we analyze the possibilities of using Saxenda, the main active ingredient of which is liraglutide, to potentiate the hepatoprotective effects of the Hepaton-vet drug in groups of rats with induced hepatopathy, evaluating the effect of these drugs on the parameters of a clinical blood test.
