Decoupling by Local Random Unitaries without Simultaneous Smoothing, and Applications to Multi-user Quantum Information Tasks

AbstractWe show that a simple telescoping sum trick, together with the triangle inequality and a tensorisation property of expected-contractive coefficients of random channels, allow us to achieve general simultaneous decoupling for multiple users via local actions. Employing both old (Dupuis et al. in Commun Math Phys 328:251–284, 2014) and new methods (Dupuis in IEEE Trans Inf Theory 69:7784–7792, 2023), we obtain bounds on the expected deviation from ideal decoupling either in the one-shot setting in terms of smooth min-entropies, or the finite block length setting in terms of Rényi entropies. These bounds are essentially optimal without the need to address the simultaneous smoothing conjecture, which remains unresolved. This leads to one-shot, finite block length, and asymptotic achievability results for several tasks in quantum Shannon theory, including local randomness extraction of multiple parties, multi-party assisted entanglement concentration, multi-party quantum state merging, and quantum coding for the quantum multiple access channel. Because of the one-shot nature of our protocols, we obtain achievability results without the need for time-sharing, which at the same time leads to easy proofs of the asymptotic coding theorems. We show that our one-shot decoupling bounds furthermore yield achievable rates (so far only conjectured) for all four tasks in compound settings, which are additionally optimal for entanglement of assistance and state merging.

Evolution of amplitude and longitude phase of tachocline rossby waves diffusing to the photosphere

Abstract Physics of MHD Rossby waves in the tachocline-layer were studied by Dikpati, Gilman, Chatterjee et al. (2020) using a fluid-particle-trajectory approach along with solving vorticity and induction equations. By extending that model to include a hydrodynamic turbulent convection zone (CZ), we examine how MHD Rossby waves generated in the tachocline might diffuse upward through the CZ to solar surface. We find that pure hydrodynamic Rossby wave amplitudes decline with height due to viscous diffusion at a rate that is independent of viscosity and increases with longitude wavenumber. Fast MHD Rossby waves amplitude declines faster with height for increasing toroidal field, due to their longitude-phase shifting with height, which increases dissipation of kinetic energy in the wave velocities. Slow MHD Rossby waves decline even faster with height because their longitude-phase shifts more rapidly with height, due to their slow phase speed. We conclude that low wavenumber HD and fast MHD Rossby waves, originating in the tachocline, might be detected at the photosphere, but slow MHD Rossby waves should be virtually impossible to detect. We infer from fluid particle trajectories that wave amplitudes declining with height and longitude phase shifting with height associated with decline, implies a powerful mechanism for tangling of magnetic fields, distinct from convective turbulence effects. This could cause a sustained or dissipative local dynamo action triggered by Rossby waves.

Exploring the perceived dynamic system driving inequities in the community obesogenic environment

Abstract Introduction Persons in socioeconomically disadvantaged situations (PSEDS) are more susceptible and disproportionally exposed to obesogenic environments, resulting in poorer dietary outcomes and lower levels of physical activity. This study aimed to map the complex dynamic system within the community obesogenic environment driving unhealthy eating and insufficient physical activity among PSEDS in Flanders, and to identify potential local actions. Methods Participatory group model building (GMB), a qualitative system dynamics method, was used to engage PSEDS (n = 7), local decision makers (n = 7) and local stakeholders (n = 5) in two Flemish municipalities. A two-day GMB session was held in each municipality during which a causal loop diagram (CLD) was created and potential local actions were identified by considering causal pathways and reinforcing loops in the system. Results The CLD was designed around two main variables (i) healthy eating and (ii) physical activity among PSEDS. Seven sub-systems could be identified: 1) social environment, 2) facilities and activities, 3) mobility options, 4) information, 5) affordability, 6) safety (specifically for physical activity), and 7) industry and advertisement (specifically for eating behaviour). Several actions to improve the local environment to promote eating behaviour and physical activity among PSEDS were identified. Conclusions The CLD illustrates the complex interactions between individual and environmental determinants contributing to inequalities in eating behaviour and physical activity by including multiple perspectives of community members in socioeconomically disadvantaged situations, local decision makers and local stakeholders. Both the participatory GMB approach and the final CLD visualization can provide the basis for planning local actions for promoting healthy eating behaviour and physical activity among PSEDS. Key messages • Group model building is an effective approach to explore and understand a dynamic complex system through a shared understanding among diverse stakeholders. • A systems approach is valuable to provide a more comprehensive and context-specific understanding of the perceived factors contributing to inequities in the obesogenic environment.

Co-planning as a public health tool: the Milan Health Protection Agencies’s Local Gambling Plan

Abstract Issue/problem Gambling represents a public health, social, and economic problem. Lombardy Region, according with national and regional law, has approved the Regional Plan for the prevention and contrast of Pathological Gambling. The Health Protection Agencies (HPA) of the Metropolitan City of Milan, as the other HPAs, implemented the Local Gambling Plan, based on a context analysis and in synergy with all the actors involved. Description of the problem Since 2019, the Milan HPA’s Local Gambling Plan has been implemented through collaboration with non-profit entities (TSEs), which are involved via public tendering. The implementation of the new Italian ‘Code of the Third Sector’ changed the TSEs engagement modalities. For this reason, a complex co-planning process has been initiated in order to increase the level of active citizenship and to enhance public health, in line with horizontal subsidiarity principle. Results The Co-planning procedure promoted the integration among local health services, non-profit entities and municipalities with the aim of gambling prevention and contrast, ensuring the continuity of prevention programs and the involvement of local stakeholders in addressing a public health issue. During the co-planning, 9 working groups were established to define objectives, project actions, monitoring and evaluation methods, ensuring the common interest of all actors involved. Lessons For the health and social system, the co-planning procedure becomes an opportunity to translate what is foreseen by the regulations into local actions. It allow the active participation of local stakeholders involved into the co-construction and achievement of public health objectives and the promotion of communities’ empowerment. Key messages • Co-planning is both a process and a tool for local welfare. • Co-planning involved multiple actors, among which the public institution that ensures satisfaction of health needs through governance actions.

What characterizes the eldercare debut? A registry-based study of pre-entry health care use

Abstract Introduction Timely identification of needs due to functional loss in old age is important. Policy guidelines requires local collaborative care action. Eldercare debut circumstances are poorly investigated from a collaborative perspective. This study explored the socio-demographic characteristics, functional status and patterns of health care use leading up to the first application for eldercare, and how older people’s intensity of primary care use was associated with their intensity of granted eldercare at debut. Methods Data on socio-demographics, functional status, and informal care in people ≥65 years (July ‘21 to June ‘22; n = 3,649) were combined with data on inpatient and outpatient care six months preceding debut in Stockholm, Sweden. Descriptive and regression statistics were used. Results Every second person debuted following a hospital stay and one in four had extensive functional limitations. The majority made one or two visits in primary care, but 13% had a high intensity of use and 20% made no visits at all. More than half received informal care weekly or daily. Non-use and high use of primary care were both significantly associated with increased probability of receiving high intensity of eldercare. Conclusions and implications The intensity of primary care use can provide an indication of people’s intensity of eldercare at debut, which is important for resource allocation. Deeper collaboration between eldercare and primary care actors can facilitate early identification of people in need of support, thereby alleviating individual suffering, enabling secondary and tertiary prevention, and optimizing the management of welfare resources. Key messages • The intensity of primary care use can provide an indication of people’s intensity of eldercare at debut. • Deeper collaboration between eldercare and primary care actors can facilitate early identification of older people with social support needs.

Mobile street clinics and harm reduction: pathways to provide care to homeless people in Brazil

Abstract Homeless people (HP) are defined as a heterogeneous group that lives in extreme poverty, with weakened or severed family ties, lacking access to conventional housing, and using public spaces as residence. In terms of health, mental health conditions are prominent as a primary treatment demand, with care aimed at addressing needs arising from the use of alcohol and other drugs being a priority in serving HP. In this context, mobile street clinics (MSC) provide health services directly in street environments, focusing on individuals who use alcohol and other substances through harm reduction approaches. Harm reduction is defined as a set of practices aimed at minimizing the adverse health effects of alcohol and drug use without necessarily eliminating usage. Moreover, it represents an ethical and political direction in care, confronting the logic of criminalization and compulsory abstinence, enhancing access to health care for alcohol and other drug users through strategies that foster autonomy development. In the current study, we conducted an integrative review assessing the facilitators and barriers for HP access to mental health services. Preliminary results indicated that MSC, the connection between healthcare workers and the HP they serve, and the implementation of local street-based actions were the main facilitators of access for individuals who engage in harmful use of alcohol and other drugs to mental health services. Conversely, stigma, services’ lack of adjustment to the lifestyles of homeless people, and excessive bureaucracy were identified as the principal barriers of access. MSC, through their harm reduction activities, have emerged as a potential care technology to facilitate access to health services for homeless people. This research aims to present harm reduction as an ethical and political direction of care through the actions of mobile street clinics, as a way to facilitate access to health services for the homeless people. Key messages • Homeless people require mental health care tailored to the use of alcohol and other drugs, and harm reduction strategies implemented through mobile street clinics prove to be an effective form of care. • Mobile street clinics and harm reduction are important care technologies that enhance access to health services for the homeless population.

Customised Methodology to Assess and Measure Effectiveness of Integrated Landscape Management Relevant Multi-Stakeholder Transformative Governance, Incorporating Rights-Based Planning and Tenure Aspects, Applied in Kenya, Nigeria, and Viet Nam

Different thinking and strategies are needed to transform our food systems at different scales. Food systems can be changed towards a more sustainable path through multi-stakeholder transformative governance at the landscape level because that is where national-level visions, objectives, and policies meet with local practice, priorities, and actions. Concrete and practical guidance on how to effectively put a multi-stakeholder transformative governance process into practice is missing. Through the Global Environment Facility (GEF) funded ‘Food Systems, Land Use and Restoration Impact Programme’, led by the World Bank, countries are supported in integrated landscape management (ILM) to ensure that production systems are embedded within wider landscapes to safeguard the natural capital and ecosystem services on which they depend. A customised methodology to assess and measure the effectiveness of ILM-relevant multi-stakeholder transformative governance, incorporating rights-based planning and tenure aspects, has been developed that makes governance explicit in the ILM process. This methodology aims to improve landscape-level institutional coordination, coherence, and collaboration through enhanced horizontal and vertical coordination and network dynamics. The conceptual framework of the customised methodology and how to operationalise it are explained and illustrated with the application in the country projects in Kenya, Nigeria, and Viet Nam. Making transformative governance explicit within the ILM process at the landscape level will require investments in time and capabilities, but allows governance to act as a catalyst towards more sustainable pathways.

Low-Carbon Rural Areas: How Are Polish Municipalities Financing the Green Future?

The main aim of the research was to assess Polish rural municipalities’ investment activity connected with the development of a low-carbon economy, supported with EU funds in the 2007–2013 and 2014–2020 financial frameworks. The empirical study was based on data from Poland’s Ministry of Development Funds and Regional Policy, Ministry of Finance, and Statistics Poland, analysed through basic descriptive statistics and a logistic model to identify key factors influencing investment activity. The study showed that the greatest number of agreements on funding were, in fact, signed by rural municipalities in the period under analysis. The predominant measures undertaken during this time were the promotion of renewable energy sources and the improvement in energy efficiency. In the earlier financial framework, low-carbon economy projects in rural areas were more often implemented by municipalities with developing demographic potential, including those characterised by a higher level of enterprise development. In the subsequent financial framework, human capital turned out to be of key importance for the investment activity of rural municipalities. Experience gained from 2007–2013 positively influenced fund absorption in 2014–2020, improving project value, number, and support. The study confirmed that rural municipalities play a vital role in advancing a low-carbon economy, as local actions are key to achieving sustainable development and reducing greenhouse gas emissions.

Determination of proinflammatory cytokine levels to assess the reparative potential of tissues in ischemic damage and local correction with hyaluronic acid

The hypothesis of the study was the assumption that local correction of secondary alteration stops excessive inflammation activity and promotes early activation of reparative processes. Objective: in an animal experiment, to evaluate the dynamics in blood plasma of the concentration of circulating inflammatory cytokines in acute ischemic damage to soft tissues and after local action of a hyaluronic acid-based drug. In anesthetized Wistar rats, acute ischemic damage to the soft tissues of the thigh was simulated by mechanical compression with a vise for 7 hours. After removing the vise, the rats were divided into 2 groups of 32 individuals: control (without treatment) and experimental (3 hours after removing the vise, the drug was injected into the area bordering the compression zone with a sterile syringe based on hyaluronic acid “Hyalift-3.5”, diluted with 0.9% solution to the final concentration of the drug – 1.75%). The concentration of cytokines in blood plasma was determined, histological sections of soft tissues in the compression area were examined. An increase in the plasma concentration of proinflammatory cytokines (IL-1β, TNFα, IL-6) was revealed during the entire follow-up period (21 days), especially 7 days after the injury. To the greatest extent, these changes were observed in animals in the control group, which was manifested by a statistically significant increase in the concentration of IL-1β, TNFα and IL-6, relative to the values in intact rats: on average by 7.2; 3.7 and 5.3 times, respectively. In rats in the experimental group, local administration of a hyaluronic acid-based drug already in the early period after injury limited the severity of inflammation (an increased concentration of IL-10 was recorded in blood plasma). The sanogenetic role of local administration of hyaluronic acid in the wound process is mediated by the relief of inflammation in the early period of damage and is realized in increasing the reparative potential of tissues according to the variant of earlier and significant formation of musculoskeletal tissue regenerates.

Social and spatial determinants of energy ageism: Calibrating social policy towards older people under the conditions of energy transition in Polish society

The article aims to identify the problems and challenges faced by senior citizens in the context of energy transition and also to develop a framework of social policy that would respond to senior citizens' concerns and is necessary for the effective implementation of the goals of the European Union's (EU) climate and energy policy. The authors focus on the analysis of the challenges of energy transition faced by older people who live in Poland in various types of buildings and use different sources of home heating. The article shows how various types of buildings constructed using different technologies and in different historical periods and located in various social and geographical spaces divide people in terms of class and also create challenges for older people related to home heating. The type of building and its place in the urban space may be a determinant of the energy poverty of its inhabitants, and the area where specific types of buildings are clustered together may affect the air quality in this part of a city. The authors suggest taking specific local and national actions as part of social policy towards older people during energy transition. The material was collected in the winter of 2024 using focus group interviews for eight groups of senior citizens differing in place of residence, type of building inhabited and source of home heating.

Functionalized Nanodiamonds for Targeted Neuronal Electromagnetic Signal Detection.

Intracellular sensing technologies necessitate a delicate balance of spatial resolution, sensitivity, biocompatibility, and stability. While existing methods partially fulfill these criteria, none offer a comprehensive solution. Nanodiamonds (NDs) harboring nitrogen-vacancy (NV) centers have emerged as promising candidates due to their sensing capabilities under biological conditions and their ability to meet all aforementioned requirements. This study focuses on expanding the application of NDs and NV center-based sensing to neuronal contexts by investigating their functionalization and subsequent effects on three distinct cell lines relevant to neurodegenerative disease research. Our study concentrates on positioning fluorescent NDs (FNDs) with NV center point defects onto neuronal cell surfaces. Achieving this through specific antibody attachment enhances the proximity of FND to neurites, facilitating the detection of local action potentials. Targeting voltage-dependent calcium channels (Cav2.2) with biotin-streptavidin-bound antibodies enables the precise positioning of FNDs. The functionalized FNDs (f-FNDs) show increased size and zeta potential, confirming the antibody presence without compromising cell viability. Two-color confocal imaging and co-localization algorithms are employed to further attest to the success of the functionalization. The f-FNDs are applied to cell cultures of three cell lines: SH-SY5Y, differentiated dopaminergic neurons, and hippocampal rat neurons; their biocompatibility and effects on synaptic activity are explored. Moreover, preliminary total internal reflection fluorescence - optically detected magnetic resonance (TIRF-ODMR) experiments across cellular sites demonstrate the magnetic field sensitivity of our sensor network. The successful establishment of this sensor network provides a platform for characterizing neuronal signaling in healthy models and conditions mimicking Parkinson's disease.

Local biodiversity actions for sustainable development goal 15 (life on land) in China

AbstractAchieving sustainable development goal (SDG) 15 (life on land) depends on local conservation efforts. However, the lack of species data and inadequate ecological corridor designs significantly hinder conservation efficiency. This study focused on Sanmenxia City in China and utilized the Integrated Valuation of Ecosystem Services and Trade‐offs model, the GeoDetector model, and the Minimum Cumulative Resistance model to identify potential habitats, their influencing factors, and ecological corridors. We then adopted a new corridor feasibility model to compare the impacts of different ecological resistance, thereby identifying key biodiversity spaces. Results indicated a decline in habitat quality since 2000, primarily influenced by climate, topography, and land use. Simulation‐derived corridors using the habitat quality method were more effective than those based on expert experience. We identified 2808.45 km2 of potential habitats and 20 critical corridors for land animals. This study deepens the understanding of ecological resistance impacts on corridors and provides new insights into local actions for SDG 15.

A systematic review of lithium biology and pharmacology and toxicological evaluation of new organic lithium salts

Objective: to systematize scientific data on biomedical studies investigating trace element lithium over the past 70 years; evaluate toxic properties of lithium ascorbate (LiAsc) as an important promising candidate molecule.Material and methods. An analysis of 49,959 publications on lithium biomedical research retrieved from PubMed/MEDLINE database was carried out using modern data mining methods developed within the framework of topological approach to recognizing (Yu.I. Zhuravlev scientific school). Publications found by experts and not indexed in PubMed/MEDLINE were used in discussing the results of a systematic analysis of publications array retrieved from PubMed/MEDLINE. An experimental study of chronic 180 day-long LiAsc (at doses of 5, 50 and 150 mg/kg) toxicity was performed on 36 “Soviet chinchilla” rabbits by assessing local irritant action. Intoxication clinical picture, body weight dynamics, water and food intake as well as physiological, hematological and biochemical parameters were analyzed.Results. Classification and systematization of all currently available publications on lithium biology and medicine were performed. It was shown that pharmacological applications of lithium salts in mental disorders as well as lithium effects on simple sugars metabolism, lipid metabolism, blood pressure regulation, hematopoiesis, inflammation and tumor growth inhibition, neurotransmitter homeostasis, neurotrophic and neuroprotective molecular mechanisms as well as homeostasis of other electrolytes comprised promising fields of lithium drug research. The prospects for using organic lithium salts, particularly LiAsc, for various therapeutic goals were also discussed. 180-day-long oral administration of LiAsc at doses of 5, 50, 150 mg/kg resulted in no macroscopic signs of local inflammatory reaction while examining its local irritant effect.Conclusion. The lithium-ion effect on neurotransmitters promotes neuroprotection and reduces a risk of addiction. The antihypertensive, antiatherosclerotic, antidiabetic, antitumor and neurotrophic effects related to organic lithium salts may be beneficial in various therapeutic applications.

Using the Capture–Recapture Technique to Supplement a Point-in-Time Count of Homeless Adults in Kittitas County, Washington

Abstract Capture–recapture (CRC) is a method of population estimation pioneered in biology that allows the surveyor to approximate the proportion of individuals who evaded sampling efforts (i.e., captures) based on repeated samples from the same population. The current national standard for estimating homelessness is a single-day enumeration called the point-in-time (PIT) count. By using a local community action agency’s homeless outreach program and a cold weather shelter as two distinct sampling sources to capture data using CRC methodology, the current study sought to estimate the homeless population in Kittitas County, Washington, and compare CRC with PIT count estimates. Four months of data collection for the two sampling sources yielded an estimate of 115 (95% CI [93, 137]) homeless individuals in the county using CRC methodology. The PIT count conducted in the same year sampled 61 individuals, supporting the idea that cross-sectional enumeration (i.e., PIT counts) underestimate the homeless population and could be supplemented by CRC methods, particularly in rural areas where resources to conduct PIT counts may be limited. Greater accuracy in homelessness enumeration may aid in advocacy efforts, provide baseline data for researching interventions designed to reduce homelessness, and yield statistics to better guide legislative and policy initiatives.

Transforming territorial governance to make it transformative: reflections from and for action research for territorial development

The challenge of the climate emergency has highlighted the relevance of local transformative action for the development of new paths to sustainability, but also the relevance of the connection between the local and the global so that these paths have a real impact. Delving into this local-global connection is key for action research, and specifically, for Action research for territorial development (ARTD) and the Pedagogical approach (PA), two action research approaches that work from and for the territories, and which are the subject of analysis in this special issue. With the aim of contributing to deepening of this relationship, this article adapts the concept of transformative governance proposed by IPBES to build an actionable framework for reflection on the contribution of territorial development policies and research to transformative governance. It then analyses the IADT and the EP with this framework and suggests strengthening the critical dimension of facilitation so that these approaches are better adapted to the challenge of climate change.

Generating and translating evidence for safe and effective medication management in aged care homes.

Generating and translating high-quality evidence is integral to providing safe and effective medication management for residents of aged care homes. Residents are often under-represented in trials of medication effectiveness and safety. This paper reviews opportunities and challenges for generating and translating evidence for safe and effective medication management in aged care homes. There are an increasing number of randomized controlled trials (RCTs) being conductedin aged care homes. Observational studies can also help address the evidence-practice gap arising from underrepresentation of residents in RCTs. Stepped-wedge and helix counterbalanced designs may help overcome limitations of traditional RCTs for evaluating medication management interventions in the aged care setting. Strategies for generating evidence include building effective partnerships with aged care homes and organizations, using novel trial designs, leveraging existing data and knowledge sharing through international platforms. Strategies for translating evidence include using quality indicators for audit and feedback, provision of education and training, engaging internal and external stakeholders, and development of local action plans and guideline implementation tools. There is an emerging interest in the role of knowledge brokers to facilitate knowledge translation. Future directions for generating and translating evidence include strengthening international research collaboration, industry partnerships, standardizing aged care home data to support national and international comparisons, and optimizing the use of technology. Initiatives may include improving access to routinely collected administrative health and medication data for conducting high-quality observational studies. Future studies should assess outcomes prioritized by residents to ensure that medication management strategies are tailored to their needs.

Intangible cultural heritage versus tourism: residents’ reactions to temporal overtourism during the Day of the Dead in Mixquic, Mexico

ABSTRACT Globalisation opens small communities and their traditions to temporal overtourism, causing adaptations in the local dynamics. This study investigates responses to overtourism during the Day of the Dead in Mixquic, a semi-rural community located in Mexico City. Employing rapid ethnography, semi-structured interviews, participant observation, and content analysis of social media, it delves into local perceptions and actions regarding temporary overtourism dynamics in a global patrimonialisation context. Results reveal a complex interplay between traditional practices, community resilience, and tourist dynamics. Despite challenges, residents show a positive attitude towards tourists, often incorporating them into ancient traditions while preserving cultural authenticity. Notably, symbolic representations of tradition persist amidst external pressures, showcasing the resilience of community identity. The study underscores the importance of embracing community-centric approaches – observing and considering the community – and innovative tourism strategies to mitigate negative impacts for a better preservation of cultural heritage. By prioritising resident values and needs, tourism can lead to practices that are beneficial to both communities and visitors. Furthermore, the research highlights the importance of observing and listening to local communities.

Incentivising Effective Indigenous Ecosystem Restoration Practices: A Synopsis of Perceptual Approaches to Local Climate Action in the Barotse Cultural Landscape

The study was premised on a generic hypothesis that attributes the status quo vis-à-vis increasing ecosystem degradation to communities’ stage-managed negligence fueled by the state’s decision about sixty years ago to start incentivising, unsustainably though, previously voluntary environmental consciousness and associated actions by the communities. Rural livelihoods are generally threatened by climate impacts, particularly for agrarian and pastoralist communities, like the study area. Although extreme weather events have always been there, the frequency of their occurrence has risen and the exposed populations have been growing. A concise illustration of the conjectures of the study is reflected in the findings which have established the contributions of indigenous ecosystem restoration efforts and general prudent environmental management under the decentralized indigenous governance system. It has further been established that the indigenous systems that flourished in the pre-independence era were curtailed by governance system shifts from the decentralized indigenous governance system to the state controlled centralized governance system effectively alienating the people from their sacred duty of directly managing their ecosystems. Further, a general neglect by the local people in ecosystem restoration has been attributed to three main factors bordering on the state’s earlier pledges, alleged corruption in contract management processes, as well as the urgency of addressing household food needs which is usually subordinated to public works like ecosystem remediation. Arising from the observed impediments to locally-led ecosystem restoration efforts, the study has recommended to intentionally incentivize indigenous ecosystem restoration efforts using the proposed modalities as outlined herein.

The impacts of COVID-19 on youth activisms in Spain (2020–2022)

ABSTRACT The COVID-19 pandemic can be considered a ‘period of emergency critical juncture’ that affected social movements and collective action. Based on this premise, this article analyses its impact on youth activisms in Spain, investigating its structural or circumstantial nature. The research used in-depth interviews and focused on three types of youth activisms - feminisms, environmentalisms, and socio-community - chosen for either their mobilising force prior to the pandemic or their relevance during it. In order to assess the temporary or permanent effects of the pandemic on these activisms, three dimensions were studied: organisational forms, mobilisation issues and repertoires of action. The results allow us to identify short-term impacts, such as the interruption of the rhythm of activism, the prominence of the virtual world, and the creation of pragmatic alliances of local collective action, while at the same time allowing us to glimpse those that may have a more structural character such as the inclusion of mental health as an issue and the normalisation of repression and criminalisation of activism in securitarian contexts.

The Enactment of Sustainable Development Goals at a Local Scale Leads to Various Implications

The hallmark of global sustainable development efforts is the Millennium Development Goals (MDGs) initiative, so the SDGs were proposed after this. Early initiatives highlighted the need for a more comprehensive and globally applicable set of goals, thus laying the groundwork for the SDGs. Among them are sustainability, ecological environment protection and so on. This article explores the local implementation and impact of the United Nations Sustainable Development Goals (SDGs). The main questions are how to effectively implement SDGs policies in different social cultures, and the role of local government and community organizations is carefully analyzed. These are also areas where SDGs can be effectively promoted at the local level through muti-stakeholder collaboration, inclusive policies and innovative approaches. And there are three field examples to prove its effectiveness. For example, sustainable transport and energy management in Barcelona, participatory planning in Kerala and community conservation in Kenya. The significance of the study highlights the key role of local action in achieving the global Sustainable Development Goals, and provides concrete cases for analysis.
