Herbs of the Middle East
Authors: Shahrajabian Mohamad Hesam , Sun Wenli
Published: February 2024

:

The Middle east and North Africa harbour many native species with pharmaceutical
and nutraceutical potential. Since the beginning of history, food and herbal medicinal plants have
been an essential part of human lives and the traditional Middle Eastern healthcare system. The
notable medicinal plants that have been mentioned in the Bible, which are common in West Asia
and some regions of North Africa, are Aloe vera, anise, balm, cassia, cinnamon, cumin, flax, and
fig. Chemical components of Aloe vera are aloin, sinapinic acid, catechin, chromone, myricetin,
quercitrin and syringic acid. Anethole, safrole, and estragole are the main chemical components of
anise. The chemical components of cassia are coumarin, emodin, cinnamyl alcohol, and cinnamaldehyde.
The major chemical ingredients of cumin are terpinene, cuminaldehyde, sabinene,
thujene, and thymoquinone. The goal of this article is to review the considerable health benefits
and pharmaceutical benefits of medicinal herbs and plants that have been neglected and underutilized
in the Middle East and North Africa, as well as to promote their utilization. On the basis of
the results, the experimented neglected medicinal plant can offer various advantages when used together
with conventional medicinal treatments for various health conditions, such as palliative
care in managing the side effects of conventional treatments, access to a wider range of treatments,
increased patient satisfaction, and improved emotional and mental well-being. Moreover,
consuming medicinal plants may help to manage and prevent diabetes, cancer, and heart disease
with notable anti-tumor, and anti-inflammatory properties.
Molecular Mechanisms of Polyphenols in Management of Skin Aging
Authors: Dwevedi Deepti , Srivastava Ankur
Published: February 2024

:

The natural process of skin aging is influenced by a variety of factors, including oxidative
stress, inflammation, collagen degradation, and UV radiation exposure. The potential of polyphenols
in controlling skin aging has been the subject of much investigation throughout the
years. Due to their complex molecular pathways, polyphenols, a broad class of bioactive substances
present in large quantities in plants, have emerged as attractive candidates for skin anti-aging
therapies. This review aims to provide a comprehensive overview of the molecular mechanisms
through which polyphenols exert their anti-aging effects on the skin. Various chemical
mechanisms contribute to reducing skin aging signs and maintaining a vibrant appearance. These
mechanisms include UV protection, moisturization, hydration, stimulation of collagen synthesis,
antioxidant activity, and anti-inflammatory actions. These mechanisms work together to reduce
signs of aging and keep the skin looking youthful. Polyphenols, with their antioxidant properties,
are particularly noteworthy. They can neutralize free radicals, lessening oxidative stress that might
otherwise cause collagen breakdown and DNA damage. The anti-inflammatory effects of polyphenols
are explored, focusing on their ability to suppress pro-inflammatory cytokines and enzymes,
thereby alleviating inflammation and its detrimental effects on the skin. Understanding these
mechanisms can guide future research and development, leading to the development of innovative
polyphenol-based strategies for maintaining healthy skin.

Natural products from various sources play a major role in the healthcare sector, mainly in
the pharmaceutical, cosmetic, agro and medical divisions. Polysaccharides are one of the important
biomacromolecules present in higher plants, animals, fungi and algae, and aid in the growth and
development of an organism. They play a vital role in regulating and maintaining cellular homeostasis
in all forms of life. They are considered bioactive polymers and possess promising beneficial
effects on human health without any harmful side effects. Among different biopolymers, polysaccharides
have gained greater attention in the area of natural products and biomedical research due to
their unique physio-chemical properties, bioactivities and health-promoting effects. The molecular
structure of the polysaccharides is highly complex, depending on their origin and the structural diversity.
Carbohydrate polymers differ largely based on their molecular weight, composition, functional
derivatives, pattern of glycosidic linkages and degree of polymerization. In recent years, seaweed
polysaccharides have been identified in large numbers and are effectively used by the food and
biotechnology industries for the production of nutraceutical and pharmaceutical products. Several
researches have demonstrated the biological activities of seaweed polysaccharides such as antioxidant,
antiviral, hypoglycemic, antidiabetic, antitumor and immunomodulatory. Moreover, there has
been a substantial increase in the utilization of natural polymeric biomaterials in the biomedical field.
This review summarizes the diverse biological effects of polysaccharides derived from different
types of seaweeds as well as their biomedical applications. The information reviewed here provides
an insight into the biopotential efficiency of algal-based polysaccharides, further help in the development
of novel pharmaceutical and biomedical products.

Published: February 2024

In response to the escalating issue of antibiotic-resistant bacteria adhering to and thriving
on medical equipment, scientists are pioneering innovative "intelligent" materials and coatings.
These advancements entail the targeted release of antimicrobial substances, specifically activated
when bacteria are detected. The next section discusses three revolutionary substances: hydrogels,
nanoparticles, and thin films. Furthermore, intelligent antibacterial materials are divided into 2
groups based on the triggering source: those that react to biological stimuli and those that react to
non-biological ones, like temperature and electric cues associated with bacterial presence, such as
pH shifts or bacterial enzyme discharge. Moreover, because of their simple construction technique,
outstanding biocompatibility, and robust antibacterial characteristics derived from polyphenols and
metal ions, metallic-polyphenolic nanoparticles (MPNs) have obtained substantial interest in tackling
antimicrobial infections. This article presents an introduction to several MPN-centered biomaterials
(like nanoparticles, coatings, capsules, and hydrogels) and highlights the latest advancements
in research in its applications for addressing microbial threats in the field of biomedicine.
Furthermore, the usage of smart materials is classified based on their application domains, encompassing
medical implants, waste reduction, and nano-engineered systems.

Published: February 2024

O presente texto trata-se de um estudo de caráter documental, sobre as diferenças percebidas no currículo da Educação Brasileira no decorrer das décadas. Nos detivemos sobre o conteúdo de Evolução. A partir das teorias curriculares, compreendemos as distinções entre perspectivas teóricas no decorrer da história da educação brasileira, as disputas de poder e os condicionantes sócio históricos nos processos de determinação do que deveria ou não constar nos currículos. Constatamos que o ensino de ciências no Brasil é negligenciado nos primeiros séculos na Colônia, passa a ser supervalorizado a partir do ideário positivista e volta a ser sucateado no contexto atual através da BNCC. Em se tratando das teorias evolucionistas, os documentos oficiais da educação nacional só fazem menção a tais discussões, a partir dos Parâmetros Curriculares de 1997, mais de um século após a publicação da obra de Darwin.

Published: February 2024

Regular physical activity has been proven to improve metabolism, slow aging, and decrease the likelihood of various health conditions such as obesity, type 2 diabetes, and cardiovascular disorders. Hence, dancing was evaluated for its effects on cardiovascular, liver enzymes, and biochemical markers among healthy adults. Forty (40) healthy adults (20-40 years old) were chosen for the study, with an average age calculated. Those with certain health conditions or habits were not allowed to participate. Twenty (20) men and 20 women were chosen for the study, which involved dancing for 15 minutes a day, five days a week, for four weeks. Pre- and post-dancing groups were compared to measure any changes. Results indicated positive effects on health and well-being. The two groups were compared to analyze changes to cardiovascular, liver enzymes, and lipid profiles over a 4-week dance intervention. Both groups received assessments before and after the program, with the initial assessment taking place at 0 weeks and a follow-up at 4 weeks. This study found that a 4-week period of dancing exercise improved cardiovascular and lipid profiles (p < 0.05) in both genders. These favorable impacts were reflected in lower systolic and diastolic blood pressure, decreased total cholesterol and triglycerides, and lowered LDL with corresponding increases in HDL. This study found that participating in a tailored dance exercise program decreased glucose, insulin, and HOMA index levels compared to pre-exercise levels. Additionally, levels of ALT, AST, and GGT dropped considerably, while ALP and LDH also decreased. Kidney function, including aminotransferase, creatinine, and uric acid, was also reduced after 24 hours of post-dancing exercise. Twenty-four hours of Post-dancing exercise was found to decrease serum IL-6, CRP, and stress hormones (epinephrine and cortisol) levels as well as increased IL-10 levels in healthy adults (P < 0.05). Dancing could be demonstrated to be a practical non-medicinal approach to help prevent metabolic syndrome and reduce inflammation through increased cortisol production in healthy adults.
Integration of Patient-Reported Outcome Data Collected Via Web Applications and Mobile Apps Into a Nation-Wide COVID-19 Research Platform Using Fast Healthcare Interoperability Resources: Development Study (Preprint)
Authors: Oehm Johannes Benedict , Riepenhausen Sarah Luise , Storck Michael , Dugas Martin , Pryss Rüdiger , Varghese Julian
Published: February 2024

BACKGROUND

The Network University Medicine projects are an important part of the German COVID-19 research infrastructure. They comprise 2 subprojects: COVID-19 Data Exchange (CODEX) and Coordination on Mobile Pandemic Apps Best Practice and Solution Sharing (COMPASS). CODEX provides a centralized and secure data storage platform for research data, whereas in COMPASS, expert panels were gathered to develop a reference app framework for capturing patient-reported outcomes (PROs) that can be used by any researcher.

OBJECTIVE

Our study aims to integrate the data collected with the COMPASS reference app framework into the central CODEX platform, so that they can be used by secondary researchers. Although both projects used the Fast Healthcare Interoperability Resources (FHIR) standard, it was not used in a way that data could be shared directly. Given the short time frame and the parallel developments within the CODEX platform, a pragmatic and robust solution for an interface component was required.

METHODS

We have developed a means to facilitate and promote the use of the German Corona Consensus (GECCO) data set, a core data set for COVID-19 research in Germany. In this way, we ensured semantic interoperability for the app-collected PRO data with the COMPASS app. We also developed an interface component to sustain syntactic interoperability.

RESULTS

The use of different FHIR types by the COMPASS reference app framework (the general-purpose FHIR Questionnaire) and the CODEX platform (eg, Patient, Condition, and Observation) was found to be the most significant obstacle. Therefore, we developed an interface component that realigns the Questionnaire items with the corresponding items in the GECCO data set and provides the correct resources for the CODEX platform. We extended the existing COMPASS questionnaire editor with an import function for GECCO items, which also tags them for the interface component. This ensures syntactic interoperability and eases the reuse of the GECCO data set for researchers.

CONCLUSIONS

This paper shows how PRO data, which are collected across various studies conducted by different researchers, can be captured in a research-compatible way. This means that the data can be shared with a central research infrastructure and be reused by other researchers to gain more insights about COVID-19 and its sequelae.

Published: February 2024

BACKGROUND

Eating disorders are a global concern and access to early treatment is critical to improve prognosis. Single session interventions have been proposed as an opportunity to provide short term support to people on waitlists for eating disorder treatment, however, there are not enough clinicians to provide this early intervention. Conversational artificial intelligence agents or “chatbots” reflect a unique opportunity to fill this gap in service provision.

OBJECTIVE

To co-design a novel chatbot capable of delivering a single session intervention for people on the waitlist for eating disorder treatment across the eating disorder diagnostic spectrum and ascertain its preliminary acceptability and feasibility.

METHODS

The study followed the design process of the Double Diamond model including four phases: discover, define, develop, and deliver. The study involved the co-design of a chatbot with 17 participants in total; 10 adults with a lived experience of eating disorders and 7 eating disorder clinicians, by conducting interviews and workshops with the participants. Feedback from the interviews and workshops of each phase informed the ideas and development of the next phase of the study. A final prototype of a single session intervention chatbot was presented to the participants in the deliver phase.

RESULTS

Qualitative thematic analysis identified four main themes that were present across the four rounds of interviews/workshops: conversational tone, safety and risk management, user journey and session structure, and content.

CONCLUSIONS

Overall, the feedback on the single session intervention chatbot was positive throughout the Double Diamond process from both people with a lived experience of eating disorders and clinicians. Incorporating the feedback across the four themes and four phases allowed for refinement of the chatbot. Further research is required to evaluate the chatbot’s efficacy in early treatment settings.

Underground Radio Communications and Radio Observation
Authors: Levin Boris
Published: February 2024

The problems of underground radio communications and radio observation are considered. The need for radio communication with people working underground is especially obvious during underground accidents. Radio observation makes it possible to monitor underground channels to detect their changes, caused, for example, by underground tunnel construction work in the border zone. Solving these problems is complicated by the sharp weakening of the signal in the ground and the presence of an interfering parallel signal propagating above the ground. Options for antennas to solve the described problems and methods for dealing with interfering signals are proposed. Receiving and transmitting centers for placing antennas are described.
Using Consumer-Generated Social Media Posts to Improve Forecasts of Television Premiere Viewership: Extending Diffusion of Innovation Theory
Authors: Goodman Casey , Donthu Naveen
Published: February 2024

This research investigated how social media can be quantified and used as an input to improve audience forecasts for television show premieres. There were two key findings. First, Twitter activity (volume of tweets and retweets) drives viewership of shows that are unscripted (i.e., reality or competition shows). From a practical perspective, Twitter activity improved prediction accuracy beyond that of forecasting inputs typically employed by the industry. The second key finding was the interaction of media attention given to a show and audience size of the show leading into (i.e., preceding) the premiere. One practical implication for network scheduling and promotion efforts is to use strong lead-in shows along with large mass media efforts for a television season’s “flagship” series that are most important for a network’s success. This research also extends Diffusion of Innovation theory (Rogers, 2003) and diffusion modeling to television entertainment consumption. Diffusion of Innovation theory predicts the importance of information dispersion across heterophilous groups (i.e., groups that are diverse). The Bass (1969) diffusion model, a statistical model introduced to describe the diffusion of innovation, also predicts that media presence (an external factor) in conjunction with consumer eWOM (an internal factor) drive premiere ratings.

Published: February 2024

Listed in this section are hydrolases not accumulated in other parts of the Concise Guide, such as monoacylglycerol lipase and acetylcholinesterase. Pancreatic lipase is the predominant mechanism of fat digestion in the alimentary system; its inhibition is associated with decreased fat absorption. CES1 is present at lower levels in the gut than CES2 (P23141), but predominates in the liver, where it is responsible for the hydrolysis of many aliphatic, aromatic and steroid esters. Hormone-sensitive lipase is also a relatively non-selective esterase associated with steroid ester hydrolysis and triglyceride metabolism, particularly in adipose tissue. Endothelial lipase is secreted from endothelial cells and regulates circulating cholesterol in high density lipoproteins.

Published: February 2024

El surgimiento de la pandemia de covid-19 propició un largo periodo de incertidumbre y una serie de desequilibrios que han conducido a una profunda crisis económico-sanitaria, sobre la que se ha perfilado una recuperación frágil y desigual. Desde el inicio de la crisis sanitaria, a nivel mundial se instrumentaron medidas de confinamiento total o parcial, distanciamiento social y diversas acciones de prevención, contención y mitigación de la transmisión del coronavirus para preservar la salud pública; así como la suspensión de actividades productivas no esenciales, que provocaron la interrupción de las cadenas de valor y dificultaron el suministro de insumos para la producción. Estas circunstancias se tradujeron en desequilibrios en la oferta y en una contracción de la demanda de bienes y servicios, lo que finalmente provocó el cierre de empresas y la pérdida de fuentes de empleo.

La pandemia COVID-19, indudablemente ha incrementado la incertidumbre ante el futuro inmediato. Su extensión, duración e impacto en la salud en la dinámica económica y en la reproducción social muestra disyuntivas que se profundizan debido a que el virus, después de 24 meses, sigue activo. Las variantes del virus SARS-CoV-2 seguirán mostrándose mientras encuentren hospederos, mientras una proporción significativa de personas no se vacunen, sea por falta de acceso o porque no las aceptan. Optar por quedarse en casa para restringir la movilidad es una opción para un reducido número de personas de la sociedad mexicana. Mismas que han tenido la oportunidad de continuar con trabajo, educación y servicios a distancia, dichas personas lo hacen porque cuentan con activos, ahorros y salarios. Sin embargo, esta situación no se observa en la mayoría de la población que requiere salir a desempeñar alguna actividad remunerada para comprar día a día lo que la vida requiere para su reproducción.

Published: February 2024

The objective of this work was to study the sudden appearance of a sinkhole in the town of Los Angeles, belonging to the municipality of Rioverde S. L. P., to avoid damage to the patrimony of the families and infrastructure of the city.

The research work consisted of 6 stages: Stage 1, a site visit to gather information about the place and obtain the impressions of the neighbors of the area of analysis (street crossing); Stage 2, sought to verify the topography of the site and locate the sources of humidification or bodies of water; Stage 3, consisted of the exploration using the manual dynamic penetrometer (MDP) and the recovery of the integral and unaltered sampling of the site; Stage 4, included the development of conventional geotechnical tests for the characterization of the soils present, determine their moisture profile, as well as determine the possibility of dispersion, piping, and collapse. In Stage 5, the stress distribution in the subsoil was modeled and in Stage 6, the conclusions are presented.

Through the MDP, an infiltration point was identified at the intersection of the streets of the study site, a frustoconical hollow with a depth of 2.80 m, with an upper diameter of 0.80 m and a lower diameter of approximately 2.00 m, was located. The depth of the GWL in the water extraction wells in the area is 12 m, the soil of the place has low Penetration Resistance up to a depth of 4.80 m. Subterranean conduits were identified that branch off in different directions, predominantly in a northeasterly direction.

The stratigraphic profile of the place corresponds to the following sequence of five strata found at a maximum explored depth of 6.00 m; the first layer is an inorganic clay of low plasticity (CL), and from the second to the fifth layer there are inorganic silts of low compressibility (ML). The second stratum is an intermediate grade dispersive soil, with appreciable strength and little deformation at its natural moisture content, however, when hydrated it experiences a slight propensity to collapse and is susceptible to erosion.

Published: February 2024

The aim of this work is to design and implement a fraction collector for liquid chromatography, a chemical method to separate the components of a mixture. A fraction collector is a piece of equipment that automatically collects each of the recovered fractions. The collector´s CAD model (Computer Assisted Design), based on a Cartesian-type system, is developed in Autodesk's FUSION360 software, in which a stress and strain study is also carried out using finite element analysis to rule out any possible structural failure. Subsequently, for its implementation, the different components of the designed CAD model were built using 3D printing. The developed system takes as input variables the number of samples to collect and the time that must elapse before changing the head to the next tube to collect the next sample. For this, a control system is implemented using the Arduino uno development board, which controls the movement in the X and Y axes of the Cartesian system through two stepper motors, as well as the user interface that consists of an LCD screen and a group of buttons that allow you to set the operating parameters and visualize the status of the equipment. The equipment designed has shown functionality like that of commercial equipment with basic characteristics, which allows obtaining precise samples efficiently and at a lower cost.

Published: February 2024

Actualmente, se están desarrollando técnicas y procedimientos para lograr diseños de mezclas asfálticas capaz de soportar altos niveles de tránsito mediante el mejoramiento del desempeño del pavimento, por lo que el objetivo de este estudio es lograr una mezcla que cumpla con las especificaciones de agrietamiento y deformación permanente utilizando una menor cantidad de cemento asfáltico, además de utilizar una mayor cantidad de pavimento asfáltico recuperado (RAP) mediante la implementación de una nueva metodología denominada Diseño Balanceado de Mezcla Asfáltica (BMD), el cual dentro de sus requerimientos evalúa el rendimiento de la mezcla en cuanto a la deformación permanente y el agrietamiento, dando un parámetro del porcentaje máximo y mínimo de contenido asfáltico que podría utilizarse en la mezcla. Para ello se ensayaron tres mezclas con diferentes porcentajes de asfalto, la primera con el óptimo (5%) obtenido mediante el análisis volumétrico Superpave, la segunda con una menor cantidad de asfalto (4.5%) y la tercera con un porcentaje mayor (5.5%), dando como resultado un rango de asfalto aceptable entre 4.8 y 4.95% cumpliendo con los parámetros evaluados. Además, se ensayaron cuatro mezclas combinados con 30% de RAP y con diferentes porcentajes de asfalto, la primera con el óptimo (4.65%), las tres siguientes con porcentajes mayores (5.15, 5.65 y 6.15%) dando como resultado el cumplimiento en el ensayo de deformación permanente, sin embargo, en el ensayo de agrietamiento resultaron ligeramente por debajo del mínimo recomendado, por otra parte, cabe mencionar que a las mezclas combinadas con RAP no se le agregó ningún aditivo rejuvenecedor, únicamente se utilizó un asfalto PG 64-22-H. Es importante mencionar que, para el diseño virgen, se logró disminuir el porcentaje de asfalto utilizado en la mezcla, contribuyendo en la optimización del costo y del uso de cementos asfálticos.

Published: February 2024

Streszczenie: W drugiej połowie 2021 roku w USA powstało nowe zjawisko zwane Quiet Quitting (QQ) dotyczące nastawienia do pracy. Zjawisko jest swego rodzaju tren- dem, który za sprawą mediów społecznościowych zyskał dużą popularność, zwłaszcza wśród osób z pokolenia Z ze względu na ich stosunkowo dużą aktywność w świecie wirtualnym. QQ dotyczy wyrzeczenia się tzw. kultu pracy oraz wykonywania swoich obowiązków służbowych na poziomie absolutnego minimum w celu zachowania work-life balance, a także uniknięcia wypalenia zawodowego. Celem niniejszego artykułu jest przedstawienie nastawienia do pracy osób z pokolenia Z pod kątem występowania w nim tendencji charakterystycznych dla zjawiska QQ, a także określenie kluczowych dla tej grupy aspektów pracy, które motywują ich do wykonywania obowiązków zawo- dowych. Można założyć, że wśród pracowników pokolenia Z zachowania charaktery- styczne dla zjawiska QQ występują w większym stopniu niż wśród ogółu polskich pra- cowników, ponieważ to oni, za pomocą mediów społecznościowych, w największej ilości wpłynęli na rozprzestrzenienie się tego trendu, zatem można zadać pytanie: czy pracownicy pokolenia Z podchodzą do pracy zgodnie z założeniami QQ? Wyniki poka- zały, że podejście do pracy osób z pokolenia Z nie pokrywa się z założeniami zjawiska QQ. Pracownicy pokolenia Z dążą do zachowania balansu pomiędzy pracą a życiem prywatnym, jednak w dalszym ciągu angażują się w obowiązki zawodowe, a praca jest dla nich istotnym elementem życia. W życiu zawodowym cenią sobie przede wszystkim dobrą atmosferę i integrację z zespołem, co też stanowi najważniejszą składową ich motywacji do pracy. Słowa kluczowe: Quiet Quitting, pokolenie Z, rynek pracy, zachowania pracowników. Kod JEL: J00, J5

Conflicts over land between Senamanenek Indigenous Peoples of Kampar Regency and PT. Perkebunan Nusantara V has occurred since the early 1990. While national legislation acknowledges adat (customary) as a legitimate basis for rights, the current legal framework presents significant hurdles for communities seeking to assert their land claims based on adat rights. As an empirical legal research, this study tries to propose a new dispute resolution model to deal with the problem. This research found that government intervention as the owner of State-Owned Company capital determines the resolution of customary land disputes such as the PTPN V and Senamanenek Indigenous Peoples disputes. The settlement was carried out after receiving a presidential order and the United Indonesia Cabinet Limited Meeting results by returning the land and its contents from the PTPN V to the government. Then, the government hands over to individual Senamanenek Indigenous Peoples members who are issued certificates of ownership through the TORA mechanism.

Autism Spectrum Disorder (ASD) is a neuro-developmental condition characterized by developmental disability, speech and language delays, abnormal social interactions, behaviour excesses and repetitive and stereotyped behavior. This research is aimed at improving the early diagnosis of ASD using deep learning technique. Raw datasets related to both Autism and Non-Autism cases were collected from the University of Califona Irvine (UCI ) repository. Multi-layer perceptron (MLP) neural network was used for the classification. Keras was used to build the MLP neural network model with the aid of Jupyter Notebook. Some of the metrics used to evaluate the model are performance accuracy, probability, roc-auc curve and confusion matrix which shows the precision, recall and F1 score. After running 7 epochs, 98.3% performance accuracy was achieved for the training data while 98.1% performance accuracy was achieved for the test data. With higher epochs, better results can still be achieved. This shows that MLP performs very well in classifying ASD dataset, making it easy for early diagnosis of the disease.

Authors: Błaszczyk Andrzej
Published: February 2024

W artykule przedstawiono problemy rozwoju cywilizacyjnego XXI wieku w warunkach procesów globalizacyjnych. Praca rzuca światło na nowe zjawiska społeczne, wydarzenia i kryzysy. Rzeczywistość współczesna jest zróżnicowana i nie może mieć cech wspólnych; te same procesy wyglądają inaczej, gdy obserwuje się je z różnych perspektyw, różnych stron świata, a także z poszczególnych punktów widzenia (np. punktu widzenia Johna Graya).
Zmiany cen skupu żywca a rozmiary produkcji w latach 1989-2000
Authors: Zajączkowska Maria
Published: February 2024

Ceny skupu mają wpływ na skalę sprzedanej produkcji rolnej. Autorka obliczyła ceny względne i rzeczywiste na podstawie własnych wzorów oraz nominalnych cen zakupu. Ceny względne porównują aktualną cenę produktu z cenami innych produktów rolnych w danym roku. Ceny realne skupu produktów rolnych pokazują zmiany siły nabywczej tych cen w danym roku w stosunku do roku bazowego. Na podstawie obliczonych cen autor stwierdził, że warunki produkcji bydła rzeźnego – wieprzowego, wołowego, drobiowego i baraniego – pogorszyły się w Polsce w latach dziewięćdziesiątych.

Immigrant Women from Iran and Afghanistan in Sweden: Experiences of Domestic Violence During the COVID Pandemic
Authors:   Linnaeus University, Sweden, Hamedanian Fatemeh
Published: February 2024

This paper explores the firsthand experiences of immigrant women victims of domestic violence amidst the COVID-19 crisis. Sixteen Iranian and Afghan women residing in Sweden were interviewed. Their responses were analyzed using qualitative content analysis. An intersectional perspective was used to understand domestic violence among the immigrant women. The study found high levels of psychological violence and controlling behavior by the women’s partners. The harm was compounded by economic instability, the temporality of residency permits, and the limited access to support services. The intersectional analysis suggests that multiple factors in the midst of the pandemic increase the vulnerability of abused immigrant women and lead to further marginalization.
