Study on the evaluation and influencing factors of contracted residents on the coordination of primary medical institutions.

The implementation of family doctor contract service is a pivotal measure to enhance primary medical services and execute the hierarchical diagnosis and treatment system. Achieving service coordination among various institutions is both a fundamental objective and a central element of contract services. The study aims to assess residents' evaluations and determining factors related to the coordination of health services within primary medical institutions across different regions of Shandong Province. The findings intend to serve as a reference for enhancing the coordination services offered by these institutions. The study employed a multi-stage stratified random sampling method to select three prefecture-level cities in Shandong Province with different economic levels. Within each city, three counties (districts) were randomly sampled using the same method. Within each county (district), three community health service centers and township health centers implementing family doctor contract services were selected randomly. Face-to-face questionnaire surveys were conducted with contracted residents using the coordination dimension of the revised Primary Care Assessment Tools Scale (PCAT) developed by the research team. Data analysis was conducted using such methods as one-way analysis of variance and multiple linear regression. The sample included 3,859 contracted residents. The coordination dimension score of primary medical institutions averaged 3.41 ± 0.18, with the referral service sub-dimension scoring 3.60 ± 0.58 and the information system sub-dimension scoring 3.34 ± 0.65. The overall score of the referral service sub-dimension surpassed that of the information system sub-dimension. Regression results indicated that the city's economic status, the type of contracted institutions, gender, education, marital status, income, occupation, health status, and endowment insurance payment status significantly influenced the coordinated service score of primary medical institutions (p < 0.05). The coordination of primary medical institutions in Shandong Province warrants further optimization. Continued efforts should focus on refining the referral system, expediting information infrastructure development, enhancing the service standards of primary medical institutions, and fostering resident trust. These measures aim to advance the implementation of the hierarchical diagnosis and treatment and two-way referral system.

Fluoride impairs vascular smooth muscle A7R5 cell lines via disrupting amino acids metabolism

Given the insidious and high-fatality nature of cardiovascular diseases (CVDs), the emergence of fluoride as a newly identified risk factor demands serious consideration alongside traditional risk factors. While vascular smooth muscle cells (VSMCs) play a pivotal role in the progression of CVDs, the toxicological impact of fluoride on VSMCs remains largely uncharted. In this study, we constructed fluorosis model in SD rats and A7R5 aortic smooth muscle cell lines to confirm fluoride impaired VSMCs. Fluoride aggravated the pathological damage of rat aorta in vivo. Then A7R5 were exposed to fluoride with concentration ranging from 0 to 1200 μmol/L over a 24-h period, revealing a dose-dependent inhibition of cell proliferation and migration. The further metabolomic analysis showed alterations in metabolite profiles induced by fluoride exposure, notably decreasing organic acids and lipid molecules level. Additionally, gene network analysis underscored the frequency of fluoride's interference with amino acids metabolism, potentially impacting the tricarboxylic acid (TCA) cycle. Our results also highlighted the ATP-binding cassette (ABC) transporters pathway as a central element in VSMC impairment. Moreover, we observed a dose-dependent increase in osteopontin (OPN) and α-smooth muscle actin (α-SMA) mRNA level and a dose-dependent decrease in ABC subfamily C member 1 (ABCC1) and bestrophin 1 (BEST1) mRNA level. These findings advance our understanding of fluoride as a CVD risk factor and its influence on VSMCs and metabolic pathways, warranting further investigation into this emerging risk factor.

Eigenvalues of quantum Gelfand invariants

We consider the quantum Gelfand invariants which first appeared in a landmark paper by Reshetikhin et al. [Algebra Anal. 1(1), 178–206 (1989)]. We calculate the eigenvalues of the invariants acting in irreducible highest weight representations of the quantized enveloping algebra for gln. The calculation is based on Liouville-type formulas relating two families of central elements in the quantum affine algebras of type A.

Marrow-ablative consolidation chemotherapy (HDCT) to decrease the development of choroid plexus carcinoma (CPC) specific relapse in high-risk TP53-mutated (germline or somatic) young children with newly diagnosed CPC.

2088 Background: Choroid plexus carcinomas (CPC) are highly malignant, early childhood cancers in which the loss of TP53 function is a central element of their development and defines unfavorable disease. To date, CPC-free survival rates have remained poor; recent data from St. Jude including complete TP53 mutation status, yielded CPC-free survival of only 29% with a non-marrow-ablative chemotherapy strategy. The rarity of CPC has constrained the ability to explore the role of HDCT with autologous hematopoietic progenitor cell rescue (AuHPCR). Previously reported results of the "Head Start" (HS) HDCT approach showed some promise of cure, but were limited by small patient numbers, short follow-up and incomplete TP53 mutation data. Consequently, the role of HDCT and AuHPCR in TP53-mutated CPC remains unclear. Methods: We have analyzed data on TP53 status, therapy, treatment responses, CPC-free and overall survivals (OS) and second cancers from the largest cohort of such patients, all who received initial therapy with the intent/consideration of undergoing consolidative HDCT. Results: Twenty-seven children with CPC (median age, 16 months) received HS-like induction chemotherapy regimens or ICE with the intent of utilizing consolidative HDCT. Twenty-three of 27 completed HDCT consolidation; the remaining 4 patients did not proceed with HDCT due to parental choice. Somatic or germline TP53 mutations were identified in 17 patients, while 4 patients exhibited TP53 wild type (TP53wt); TP53 status remains untested or unavailable in 6 patients. Five-year CPC-free survival and OS for the entire cohort were 47.8% and 44.4%. CPC-free survival for those with TP53 germline mutations (n=12) was 66%, for those with somatic tumor TP53 mutations (n=5) was 40% and for those with confirmed TP53wt (n=4) was 50%. The 5-year CPC-free survival for all 23 patients who underwent HDCT and AuHPCR was 52%, comprising 3/4 TP53wt patients, 10/12 TP53 germline mutated patients and all 5 TP53 somatic tumor mutated patients. Notably, all six survivors with TP53 mutations had undergone HDCT with AuHPCR, and all but one avoided irradiation. Eight out of 12 patients with documented genotypic (TP53 germline mutated) Li-Fraumeni Cancer Predisposition Syndrome (LFS) developed second malignancies. Conclusions: Our data indicate that HDCT with AuHPCR consolidation is associated with improved CPC-free survival compared with historical reports in young children with high-risk TP53 mutated CPC. However, the ultimate development of second cancers substantially affects outcomes for those with LFS, irrespective of HDCT treatment. These data justify the inclusion of HDCT and AuHPCR in the prospective international trial under development for young children with newly diagnosed TP53 mutated CPC.

Economic Effects of rising Energy Prices

Abstract Energy is an indispensable resource for everyday activities, both for the population and for economic operators. Being used for heating, cooling, and lighting buildings, driving, and putting into operation various machines, energy is essential for the entire economy. Since energy is a central element of human activity and energy prices are the quasi-permanent component in most costs, its price can be called "the most important price in the economy". The topic of the research is a highly relevant issue for both financial and energy sectors. The research aims to identify and analyse the economic effects of energy price increases. Among the proposed objectives are: to gain in-depth knowledge of the scientific background of the subject under investigation; to determine the role of energy in a country's economy; and to determine the economic and social consequences of energy crises. Using the qualitative research method, this article is the result of an integrative consultation of a large, rich, and recent scientific literature. To achieve the established objectives, official documents of the European Commission and the United Nations, reports of the International Monetary Fund, the European Central Bank, and the National Bank of Romania, academic articles and studies elaborated by various prestigious think tanks were studied. The first part of the paper briefly outlines the importance of energy for a country's economy. The second part reviews the scientific literature, thus illustrating the distinct opinions of various experts in the field. The third part presents the economic effects of energy crises and analyses the impact of rising energy prices on inflation and economic activity from a theoretical perspective.

INBio: its innovative work in the knowledge and sustainable use of biodiversity in Costa Rica

The National Institute of Biodiversity of Costa Rica (INBio), the first institution of its kind worldwide, was created in 1989 as a civil society organization, with the mission of promoting greater awareness of the value of biodiversity, to achieve its conservation and promote human development. It operated within the framework of a national biodiversity conservation strategy consisting of three types of actions: “save, know and use”, forming a public-private alliance with the National System of Conservation Areas, whose work represented the first step of “saving”. INBio focused on the generation of scientific knowledge of Costa Rican biodiversity (knowing) and the search and promotion of its intelligent use (using). This article describes the genesis of the institution and its main contributions to the knowledge and use of Costa Rican biodiversity between 1989-2015. These include the results of the protected areas biodiversity inventory process and the development of the largest systematic collection of biological specimens in the country's history, fully systematized; the development of an information management system that integrated all the information from the inventory and the specimens in its collection in digital format, allowing global access to this information or its correlation with that of other sources. The results of promoting and facilitating the use of information through five programs: Natural Sciences and Conservation Biology, for scientific purposes; Bioliteracy and Education, conceptually designed for the teaching and development of awareness about the value of biodiversity; Bioprospecting, the systematic search for economic uses of biodiversity for medicinal, agricultural and industrial purposes; Conservation for Development, the use of the information for wild areas conservation purposes, surrounding communities or nature tourism, among others; Technical Assistance and Training, program in charge of assisting public and private entities, inside and outside the country, in the development of initiatives in which Biodiversity was the central element. The main results of its work and the national and international awards that INBio received for its innovative approaches and contributions are described, as well as the financial and political reasons why INBio discontinued its activities in the period 2015-2016 are summarized. Viewing the work of INBio as a first stage, the importance and need to continue with a state program on the knowledge and use of Costa Rican biodiversity is raised, in addition to its protection, with the goal of creating awareness of its value before the serious threats to life on Earth.

This paper presents a compact lightweight beam-reconfigurable antenna system for unmanned aerial vehicles (UAVs). The antenna system consists of a central active monopole element surrounded by eight parasitic elements, which can be controlled using PIN diodes to switch the beam across four elevation angles and eight azimuth beams. This beam-reconfigurable antenna system has several advantages over traditional UAV antennas, including light weight, efficiency, and compactness. The antenna system operates at 5.09 GHz and achieves a measured peak gain of 4.55 dBi, with a remarkably low weight of 9 g and a size of 1.00λ0×1.00λ0×0.22λ0.

EFFECT OF THE FEED GAS MIXTURE COMPOSITION AT METHANOL DEHYDROGENATION TO FORMALDEHYDE ON SUPPORTED OXIDE CATALYSTS

The article presents the results of a study of the activity of deposited oxide catalysts in the process of obtaining formaldehyde from methanol. Model catalysts were prepared by impregnation of finely porous silica gel with nitrate solutions of zinc, copper, silver, sodium, followed by heat treatment. The catalytic properties of the samples were studied in the reaction of methanol dehydrogenation in the flow mode on a fine fraction of the catalyst. With the complication of the composition of the feed gas mixture, part of argon was replaced with hydrogen, mono- and carbon dioxide. The reaction mixture was analyzed by gas chromatography, IR spectroscopy and photocolorimetry. At a temperature of ~350 °C, a noticeable formation of formaldehyde begins, upon reaching a temperature of 500 °C in the reactor, methanol processing begins to decrease, while the concentration of formaldehyde changes insignificantly. Along with formaldehyde, dimethyl ether, methane and carbon dioxide are fixed in the reaction products. At the end of the tests on the surface of the catalyst, carbon, oxygen and hydrogen are quantified using elemental analysis methods, the ratio between which corresponds to the formula (-COH-)n. That is, along with the target reaction, methanol is consumed for the formation of surface hydrocarbons. Oxymethylene oligomers can decompose along two competing routes to form formaldehyde or carbon and CO2. The addition of carbon dioxide to the feed gas mixture after the catalyst enters the stationary mode leads to a significant increase in its formaldehyde yield. It is obvious that the route with the formation of carbon dioxide is associated with the target reaction of formaldehyde production, where the catalytic reaction maintains a certain concentration of active centers. Thus, it can be assumed that carbon dioxide as a product of decomposition of surface oxymethylene compounds affects the rate of the catalytic reaction by maintaining a certain concentration of surface hydrocarbons, which are necessary as an element of the active catalytic center.

Linking crises: inter-crisis learning and the European Commission’s approach to the National Recovery and Resilience Plans

AbstractThe article examines potential linkages between the management of the Eurozone crisis and the EU’s economic response to the COVID-19 pandemic. It does so by focusing on the Commission and its approach to conditionality-based lending. The analysis employs the concept of inter-crisis learning to argue that the lessons the Commission drew from the Eurozone crisis informed its conditionality-related proposals for the National Recovery and Resilience Plans (NRRPs). By using qualitative data, including eight elite interviews, the article suggests that the Commission derived lessons regarding the design, negotiation, implementation, and monitoring of conditionality programs. These lessons led to cognitive changes within the organisation and to behavioral changes that were reflected in its proposals regarding the conditionality attached to NRRPs. The article contributes to the literature examining the EU’s economic response to the pandemic by discussing the Commission’s drivers and preferences during that period. It also complements the literature on coordinative Europeanisation by offering insights on how the European Commission shapes its proposals on conditionality-based lending; a central element of its relationship with member states when it comes to crisis management. Finally, it discusses the implications of the article’s main thesis for the process of European integration.

Factors associated with the satisfaction of parents of children hospitalized in the pediatric ward in Togo.

Introduction : Patient satisfaction is a central element in the evaluation of the quality of care. The objective of the study was to describe the factors associated with the satisfaction of parents of children hospitalized in the pediatric ward at the Sylvanus Olympio Teaching Hospital. Patient and method: A cross-sectional study with an analytical aim was carried out between June and August 2022 in the pediatric ward at the the Sylvanus Olympio Teaching Hospital. Results: A total of 165 parents agreed to participate in our study. The mean age (+/- standard deviation) of the parents was 33.5 years (+/- 8.8). The main elements associated with good satisfaction were: reception (p= 0.009), execution of care (p&lt;0.001) and reaction of caregivers when called (p&lt;0.001). The cost of hospitalization was high according to 69.7% (115) parents and the quality of equipment was poor according to 41.2% (68) others. Conclusion : Satisfaction was statistically significant between the reception, the care received and the reaction of the caregivers to the children's complaints and not the socio-demographic characteristic.

Conformational and Substitution Effects on the Donor and Reducing Strength of Tin(II) Porphyrinogens.

Meso-octaalkylcalix[4]pyrrolates are a class of redox-active porphyrinogen ligands. They have been well established in d- and f-block chemistry for over three decades but have only recently been introduced as ligands for p-block elements. Here, we present a study on the influence of meso-substituents on the redox chemistry of calix[4]pyrrolato stannate(II) dianions [2R]2- (R=Me, Et). Expansion of the normal-mode structural decomposition (NSD) method, well known for porphyrin chemistry, provides insights into the ligand conformation of a calix[4]pyrrolato p-block complex. Combined with the results of spectroscopic donor scaling, electrochemical studies, and quantum mechanical bond analysis tools, subtle but significant substitution and conformational effects on the electronic structure are revealed. Exploiting this knowledge rationalizes the role of this class of tin(II) dianions to act as potent reducing agents, but can also be expanded for other central elements. Photoexcitation boosts this reactivity further, allowing for the reduction of even challenging chlorobenzene.

Perumusan Masalah Kebijakan, Alternatif Kebijakan, dan Rekomendasi Kebijakan dalam Mempengaruhi Perkembangan Kurikulum Pendidikan

The curriculum is a central element in the education system that plays an important role in determining the direction and goals of education. A quality and relevant curriculum is the key to producing young people who are competent and able to answer future challenges. In an ever-evolving global context, the dynamics of change and demands on education systems are increasingly complex. This encourages the need for continuous curriculum adjustment and development. Effective curriculum development cannot be done in isolation from education policy. The right education policy is the foundation for the formulation of a quality and future-oriented curriculum. This study aims to provide input and enrich understanding of the systematics of policy problem formulation, policy alternatives and policy recommendations in influencing the development of the educational curriculum and assisting education stakeholders in the process of developing an educational curriculum. This research is qualitative research using literature study methods or literature research. The formulation of policy problems, policy alternatives, and policy recommendations are three important elements that are interrelated and have a significant influence on policy making. Public policies are detailed so as to be able to find which things are important in making decisions. Education policy is a part of public policy that is closely related and influences each other.

Characterizing sulfur redox state and geochemical implications in deep-time using mineral chemistry network analysis

Sulfur (S) is a central element in global biogeochemical cycling and Earth’s redox evolution. Minerals that contain S are an important record of local environmental conditions at the time of their formation based on chemical speciation and redox. However, the oxidation state of S for hundreds of different S-containing minerals and thousands of S-containing mineral localities is unknown, largely sulfides and sulfosalts, and the redox state alone does not fully capture mineral chemistry diversity, thus limiting understanding of S redox evolution. Here, we use mineral chemistry network analysis and the weighted Mineral Element Electronegativity Coefficient of Variation (wMEECV) metric to investigate the element interactions and localities of S-containing minerals from the Mineral Evolution Database (MED) to infer the redox state of S in minerals where the redox state is unknown (SU). Louvain community detection of the S mineral chemistry redox network reveals that there are three main network communities that are separated by redox state. The S6+ community includes minerals that contain the S6+ redox state and a small number of S4+ and S2+ minerals, the S2− community includes S2−-containing minerals, and the SU community includes minerals in which the redox state of S is unknown. The wMEECV values of the SU community closely overlap with the wMEECV values of the S2− community, and do not overlap with the wMEECV values of the S6+ community, indicating the SU community minerals contain predominately reduced S. Assuming that SU community minerals contain reduced S, as supported by their network chemical associations and wMEECV values, then reduced S-containing minerals make up approximately 81 % of S-containing mineral localities in the S mineral chemistry network, even though the majority of all mineral localities (S-containing and non-S-containing) are oxygen (O)-containing minerals. Additionally, reduced S-containing minerals make up the majority (∼75 %) of all non-O containing mineral localities in the MED, representing the importance of reduced S as an electron source and substrate in the evolution of microbial metabolic networks. The range wMEECV values of S6+ community minerals expands through time due primarily to formation of chemically diverse sulfate minerals, coinciding with crustal oxidation from the late Proterozoic to Phanerozoic and the expansion of the marine sulfate reservoir. The intersection of shared constituent elements among reduced and oxidized S in the mineral chemistry network represents redox convergence of weathered S in the geosphere that was crucial in the formation of natural resource deposits and the evolution of biogeochemical cycles.

Insights into the fluid dynamics of the Bach impeller

The Bach impeller is a novel impeller that was purposefully designed to reduce power consumption as well as shear stress levels in stirred bioreactors. Contrary to conventional impellers where stirring is achieved by the pushing action of the blades, the Bach impeller relies on a central spiral element which induces an up-pumping central vortex and discharges the flow in the tangential direction through vanes. This feature is new and relevant to the field of biochemical engineering where cell culture and microbial fermentation often make use of shear-sensitive, living organisms to produce biopharmaceuticals and medicines. This article offers a thorough characterisation of the fluid mechanics of this impeller by means of 2D phased- and time-resolved particle image velocimetry (PIV) experiments. Key flow dynamics parameters including velocity magnitudes, kinetic energy, and shear stresses were estimated for different combinations of impeller size, clearance, and speed. The standard impeller size, D/T=0.52, performed most promisingly in combination with an off-bottom clearance of C=0.6 T, as the elevated impeller height allowed to pull high momentum fluid to the upper part of the tank and therefore improved overall transport phenomena in the entire reactor volume. For this impeller diameter-clearance combination peak ensemble-averaged shear stresses at the vessel base were lower due to the impeller greater distance from the bottom. A distinctive feature of the Bach impeller was its "smooth operation" mode, where velocity fluctuations due to the vane passages are nearly negligible (∼5 % of ensemble-averaged kinetic energy). These aspects make of the Bach impeller an appealing option in the context of stem cell bioprocess applications.

APEX: affordance-based plan executor for indoor robotic navigation

ABSTRACT The concept of affordance is commonly described as the set of possibilities an environment offers an animal to select and execute actions. In the context of autonomous robot navigation, determining which affordances are available to a mobile agent provides crucial information to perform navigation tasks such as executing navigation plans or exploring new environments. In this work, we provide a robot with the capability of detecting changes in the set of navigation affordances that it has available as it moves through indoor spaces. Specifically, given a navigation plan represented as a sequence of high-level behaviors such as ‘turn left’ or ‘follow a corridor’, we propose the Affordance-Based Plan Executor (APEX) as a new learning-based method to execute this plan based on the identification of navigation affordances. As a relevant fact, the proposed method does not require a map of the environment at execution time. To the best of our knowledge, our work is one of the first to explicitly consider the identification of navigation affordances as a central element to implement the execution of a behavior-based navigation plan in an indoor environment. Our experiments using the Gibson simulator and environments from the Stanford 2D-3D-S dataset suggest that our approach performs well in previously seen environments in comparison to baselines, exceeding alternative approaches' success rate by up to 43%. Additionally, our approach shows promise at generalizing to previously unseen environments, exceeding the success rate of alternative approaches by up to 26.3%. Finally, our experiments confirm that explicit reasoning about affordances is key to APEX's performance.

The role of perceived stress and social support in nursing students’ satisfaction with their initial clinical placement: A cross-sectional study

AimTo explore: a) students’ perceived stress, social support and satisfaction with their initial clinical placement; and b) identify the relationship between perceived stress, social support and student’s satisfaction with their initial clinical placement. BackgroundClinical placements are a central element in shaping future nursing professionals. Students’ satisfaction with clinical placements influences their learning outcomes and intention to continue their studies. Students experience stress from various sources during their clinical placements and social support has been found to moderate their stress. However, there is a paucity of studies addressing the associations between perceived stress, social support and satisfaction with the initial clinical placement. DesignQuantitative cross-sectional study. MethodsParticipants included 165s-year nursing students enrolled in the bachelor’s program at a central university in Israel during their initial clinical placement. Data were collected between December 2022 and February 2023 using an online questionnaire that contained four parts: personal details, perceived social support, perceived stress and satisfaction with clinical placement. ResultsStudents’ perceived stress was found to be negatively correlated to satisfaction with their clinical instructor (r = -0.47, p < 0.001) and with their clinical placement (r = -0.47, p < 0.001). Positive associations were found between satisfaction with the clinical placement and satisfaction with the clinical instructor (r = 0.67, p < 0.001). Significant differences were found in perceived stress and social support according to sociodemographic characteristics. Students perceived stress, social support from family and friends and satisfaction with their clinical instructor explained 54% of their satisfaction with their initial clinical placements. ConclusionsClinical instructors and nurse educators are central to students’ initial clinical experience. It is recommended that they assess students’ perceived stress in the clinical environment, integrate stress reduction strategies into the curriculum and encourage students to turn to various sources for social support. These can promote students’ satisfaction and success in their studies.

HETEROSKEDASTICITY ROBUST SPECIFICATION TESTING IN SPATIAL AUTOREGRESSION

Spatial autoregressive (SAR) and related models offer flexible yet parsimonious ways to model spatial and network interactions. SAR specifications typically rely on a particular parametric functional form and an exogenous choice of the so-called spatial weight matrix with only limited guidance from theory in making these specifications. Also, the choice of a SAR model over other alternatives, such as spatial Durbin (SD) or spatial lagged X (SLX) models, is often arbitrary, raising issues of potential specification error. To address such issues, this paper develops a new specification test within the SAR framework that can detect general forms of misspecification including that of the spatial weight matrix, the functional form and the model itself. The test is robust to the presence of heteroskedasticity of unknown form in the disturbances and the approach relates to the conditional moment test framework of Bierens ([1982, Journal of Econometrics 20, 105–134], [1990, Econometrica 58, 1443–1458]). The Bierens test is shown to be inconsistent in general against spatial alternatives and the new test introduces modifications to achieve test consistency in the spatial setting. A central element is the infinite-dimensional endogeneity induced by spatial linkages. This complexity is addressed by introducing a new component to the omnibus test that captures the effects of potential spatial matrix misspecification. With this modification, the approach leads to a simple pivotal test procedure with standard critical values that is the first test in the literature to have power against misspecifications in the spatial linkages. We derive the asymptotic distribution of the test under the null hypothesis of correct SAR specification and prove consistency. A Monte Carlo study is conducted to study its finite sample performance. An empirical illustration on the performance of the test in modeling tax competition in Finland is included.

Ecological grief as a crisis in dwelling

AbstractIn the current context of widespread environmental collapse, ecological grief—the sense of loss that arises from experiencing environmental destruction—has become a burgeoning topic of inquiry across psychology, geography, and anthropology. The central challenge in the study of ecological grief is that its theoretical foundations remain underdeveloped. Recent discussions in philosophy of emotions elucidate that a central element in this theoretical challenge is determining what the object of ecological grief is. In turn, our understanding of the object of ecological grief goes hand in hand with our understanding of the nature of ecological grief. This paper develops a phenomenological analysis of cross‐cultural subjective reports that identifies crucial themes in the experience of ecological grief. This phenomenological analysis reveals the object of ecological grief as the loss of the life possibilities that are sustained by dwelling. The resulting view is that ecological grief corresponds to a crisis in dwelling—a disturbance in the very way we inhabit our home environment.

AGRICULTURAL COOPERATIVES IN THE ROMANIAN AGRI FOOD SYSTEM

In the recent years, agricultural markets and supply chains have been quite strongly affected, in an unprecedented geopolitical and economic context, caused by the COVID-19 pandemic, the war in Ukraine, climate change and the challenges of implementing the European Green Deal. Under these conditions, food has once again emerged as a central element of life, alongside health, and healthy eating for all depends more on social and economic conditions than on the technical aspects of food production and processing. Thus, the need to rethink and revalue local productions, supply chains and the links established at territorial level, in order to increase the resilience of agri-food systems and ensure their sustainable development, emerged. The cooperative model is considered to be suitable to address the challenges generated by transitions to sustainability, and agricultural cooperatives can significantly contribute to increasing the resilience of agri-food systems. Many agricultural cooperatives, from different countries of the world, have managed to adapt to the new situation, proving that they are important entities in the agri-food system. In this paper, we tried to identify some particularities regarding the changes in the cooperative system in Romania, in recent years, as a reaction to the challenges that the agri-food system has to face. For this purpose, we analysed the evolution of agricultural cooperatives before and after the COVID-19 pandemic and estimated the market share in different areas of activity with significant turnover, the evolution of some economic indicators, as well as their dynamics by counties and regions in an attempt to identify their development trends.

Media and Natural Disasters: Organising Storytelling in the Age of Climate Change

Starting on 2 November 2023, some territories in the Region of Tuscany in Italy were hit by exceptionally intense meteorological and calamitous events. The Region of Tuscany’s government was immediately at the forefront of relief, assisting the population, and aiding restoration. On 3 November, a national state of emergency was declared due to flooding. Journalistic communication is an essential aspect of disaster mitigation, preparedness, response and recovery. In terms of protecting people and reducing damage, journalists and the media have an important role to play. This article reports an Italian case study analysing the behaviour of local media in cases of natural disaster. Nine focus groups were conducted with local journalists covering the flood emergency. The results highlight the role of social and institutional mediation, rather than mere dissemination, played by the local press in emergency situations, a central element in the construction of a community bond, precisely in moments of insecurity and disorientation. The narration of a disaster from the inside seems to have allowed the emergence and representation of hitherto unknown social realities in Tuscany. The goal of the news coverage was widened, making it possible to respond better to the diverse interests of the reading public and to satisfy in a short time and exhaustively the information needs of individual communities in difficulty.
