Compared to its ubiquity, social media use remains a divisive topic in the public sector. While local governments have increasingly adopted social media to increase civic engagement, many are still hesitant. Among the many factors that may have influenced the adoption of social media in local governance, we argue that community diversity deserves more attention. This study theorizes the relationship between local governments' use of social media and community diversity. We examine this relationship within the context of township governments, which is an understudied area of research in public administration. The results indicate that community diversity is related to an increase in social media use. We discuss the theoretical and practical implications of our findings and suggest fruitful avenues of inquiry in public administration social media research. [ABSTRACT FROM AUTHOR]

Gridpoint discretization of the model has a significant impact on the accuracy of finite-difference seismic waveform simulations. Discretizing the discontinuous velocity model using local point medium parameters can lead to artefact diffraction caused by the stair-step representation and inaccuracies in calculated waveforms due to interface errors, particularly evident when employing coarse grids. To accurately represent model interfaces and reduce interface errors in finite-difference calculations, various equivalent medium parametrization methods have been developed in recent years. Most of these methods require volume-integrated averaging calculations of the medium parameter values within grid cells. The simplest way to achieve this volume averaging is to apply numerical integration averaging to all grid cells. However, this approach demands considerable computational time. To address this computational challenge, we propose employing a set of auxiliary grids to identify which grid cells intersected by the welded interface and perform volume averaging only on these specific cells, thereby reducing unnecessary computational overhead. Additionally, we present a 3-D tilted transversely isotropic equivalent medium parametrization method, which effectively suppresses interface errors and artefact diffraction under the application of coarse grids. We also provide an approach for computing the normal direction of the interface, which is essential for the tilted transversely isotropic equivalent medium parametrization. Numerical tests validate the accuracy of the tilted transversely isotropic equivalent medium parametrization method and demonstrate the practicality of the implementation proposed in this paper for complex models.

We studied the physical conditions in the local interstellar medium (ISM) and at high redshift by fitting observed column densities of CO and H2 rotational levels and C  i fine-structure levels using photodissociation models calculated with the Meudon PDR code. We analysed CO absorption systems in 28 sight lines in the local ISM and seven damped Lyman-α absorption systems at high redshift, covering |$N({\rm H_2})=10^{19}\!-\!10^{21.5}\,{\rm cm}^{-2}$| and |$N({\rm CO})=10^{13}\!-\!10^{18}\,{\rm cm}^{-2}$|⁠. We constructed a method to accurately calculate CO excitation, incorporating the effects of photon trapping. Our findings indicate that in the local ISM, CO excitation is primarily driven by collisions and excitation due to the CMB radiation. We demonstrated that an increase in CO excitation observed near |$N({\rm CO})\simeq 10^{15}~{\rm cm^{-2}}$|⁠ , is attributed to an increase in gas densities from |${\simeq}100\,{\rm cm}^{-3}$| to |${\simeq}300\!-\!1000\,{\rm cm}^{-3}$|⁠. CO absorption systems in the local ISM are characterized by a gas number density of about 10–1000 cm−3, a kinetic temperature of 10–100 K, and an intensity of external UV field ranging from 0.1 to 10 units of Mathis field. Compared to the average gas probed by C  i absorption, the gas detected in CO is denser and colder, while the external UV field remains nearly constant. We observed a negative correlation between the kinetic temperature and both N (CO) and N (H2), with power-law slopes of |$-0.21\pm 0.02$| and |$-0.65\pm 0.05$|⁠ , respectively. At the same time, the gas number density exhibits a positive correlation with N (CO) and N (H2) with slopes of |$0.38\pm 0.02$| and |$1.15\pm 0.05$|⁠ , respectively. [ABSTRACT FROM AUTHOR]

Studies on journalistic work and production on social media typically focus on large media outlets in developed countries. In this article, we shift the lens to a peripheral area of a peripheral country: Argentine Patagonia. Our objective was to analyse journalistic production on Instagram, Facebook, and Twitter in the eight most-followed local and regional news media outlets. We analysed the narratives, the extent to which they apply transmedia journalism, and how they have evolved compared to studies from 2021. We also conducted structured interviews with social media managers to gain insight into their professional practices. We conclude that, 15 years since the creation of the first profiles, promoting website content remains the primary goal of North Patagonian media networks. Since 2021, there have been more frequent updates but less native production, especially on Facebook and Twitter. Despite the shortage of staff and precarious working conditions, some news media outlets have been able to innovate on Instagram, introducing a variety of multimedia formats, a more conversational tone, diverse update rhythms, adapted content, and even specific content that is organised into sections. Information production for the platforms has been integrated into journalistic routines even when public interaction with the audience remains very limited. [ABSTRACT FROM AUTHOR]

This comparative study analyzes fifteen local digital newspapers from Chile, Peru and Colombia with the objective of investigating how audience feedback influences editorial decisions. A qualitative methodology was used based on semi-structured interviews carried out with editors of the most read Web portals in the five cities with the largest population in each country. The most notable results reveal notable similarities between the media of each nation, evidencing a strong influence of audience feedback on editorial decisions, changes in business models from digital transformation and the use of tools for measuring results, collection of insights and contact with users. This finding suggests the importance of understanding and responding to audience preferences and opinions for local digital media in the region, highlighting the need for editorial strategies that encourage audience participation and engagement.

Background: Globally alcohol consumption is a leading risk factor for premature death and disability and is associated with crime, social and economic consequences. Local communities may be able to play a role in addressing alcohol-related issues in their area. Objectives: To evaluate the effectiveness and cost–benefit of an asset-based community development approach to reducing alcohol-related harm and understand the context and factors that enable or hinder its implementation. Design: A mixed-methods evaluation. Area-level quasi-experimental trial analysed using four different evaluation methods (a stepped-wedge design where each area was a control until it entered the intervention, comparison to matched local/national controls and comparison to synthetic controls), alongside process and economic evaluations. Setting: Ten local authorities in Greater Manchester, England. Participants: The outcomes evaluation was analysed at an area level. Ninety-three lay persons representing nineareas completed questionnaires, with 12 follow-up interviews in five areas; 20 stakeholders representing ten areas were interviewed at baseline, with 17 follow-up interviews in eight areas and 26 members of the public from two areas attended focus groups. Interventions: Professionals in a co-ordinator role recruited and supported lay volunteers who were trained to become alcohol health champions. The champion's role was to provide informal, brief alcohol advice to the local population and take action to strengthen restrictions on alcohol availability. Main outcome measures: Numbers of alcohol-related hospital admissions, accident and emergency attendances, ambulance call-outs, street-level crime and antisocial behaviour in the intervention areas (area size: 1600–5500 residents). Set-up and running costs were collected alongside process evaluation data exploring barriers and facilitators. Data sources: Routinely collected quantitative data on outcome measures aggregated at the intervention area and matched control and synthetic control areas. Data from policy documents, licensing registers, meeting notes, invoices, time/cost diaries, training registers, questionnaires, interviews, reflective diaries and focus groups. Results: The intervention rolled out in nine out of ten areas, seven of which ran for a full 12 months. Areas with better-established infrastructure at baseline were able to train more champions. In total, 123 alcohol health champions were trained (95 lay volunteers and 28 professionals): lay volunteers self-reported positive impact. Champions engaged in brief advice conversations more readily than taking action on alcohol availability. There were no consistent differences in the health and crime area-level indicators between intervention areas and controls, as confirmed by using three different analysis methods for evaluating natural experiments. The intervention was not found to be cost-beneficial. Limitations: Although the sequential roll-out order of the intervention was randomised, the selection of the intervention areas was not. Self-reported impact may have been subject to social desirability bias due to the project's high profile. Conclusions: There was no measurable impact on health and crime outcomes. Possible explanations include too few volunteers trained, volunteers being unwilling to get involved in licensing decisions, or that the intervention has no direct impact on the selected outcomes. Future work: Future similar interventions should use a coproduced community outcomes framework. Other natural experiment evaluations should use methodological triangulation to strengthen inferences about effectiveness. Trial registration: This trial is registered as ISRCTN81942890.

Plain language summary: What was the question?: Alcohol consumption puts an individual's health and social relationships at risk of harm. The more a person drinks, the more harmful it is. The harmful effects can place a burden on emergency services and hospitals. We wanted to find out whether community members can make a difference by taking action to address alcohol harm in their local area. What did we do?: Local councils in Greater Manchester developed a project called Communities in Charge of Alcohol, where volunteers in targeted local areas were trained to become 'alcohol health champions'. Alcohol health champions gave alcohol-related brief advice to people to help them drink less. They had a say about when, where and how alcohol is sold by reporting issues to their local council. We compared numbers of alcohol-related hospital admissions, accident and emergency attendances, ambulance call-outs and reports of crime and antisocial behaviour between areas that had alcohol health champions with other similar areas in England that did not. We calculated how much it costs to run and whether Communities in Charge of Alcohol could save society money. What did we find?: Not as many volunteers came forward to become an alcohol health champion as hoped for. Those who did give alcohol-related brief advice to people. They preferred not to report issues about alcohol sales to their local council, either because it was too complicated or because they did not want to be called a 'grass'. We did not find levels of alcohol harm changed in the Communities in Charge of Alcohol areas. Because of this, we could not demonstrate that Communities in Charge of Alcohol could save society money. What does this mean?: Getting involved in alcohol licensing decisions needs to be made easier for communities, with more anonymity, through the support of professionals. More work needs to be done to understand whether giving brief advice can reduce alcohol harm in whole communities. Scientific summary: Background: The availability of, and access to, alcohol is a key determinant of alcohol harm, and powers exist within the Licensing Act 2003 of England and Wales that enable the public to influence the local sale and supply of alcohol. At an individual level, implementing programmes to promote early risk identification and brief advice have the potential to reduce alcohol consumption and prevent alcohol-related harm, but there is a dearth of evidence to determine the feasibility and effectiveness of lay people having a role. The Greater Manchester (GM) Combined Authority (GMCA) and Greater Manchester Health and Social Care Partnership (GMHSCP) designed a new programme, 'Communities in Charge of Alcohol' (CICA) in 2017 to train lay volunteers to become alcohol health champions (AHCs), who would be able to (1) give alcohol-related brief advice to individuals and (2) help communities influence alcohol availability and strengthen restrictions in alcohol risk environments. Overall aims: To evaluate the effectiveness and cost–benefit of implementing a locally delivered AHC intervention and understand the context and factors that enable or hinder the intervention. Objectives: Relating to the outcome evaluation: to determine the effect on area-level key health performance indicators: alcohol-related hospital admissions (narrow measure), weekend accident and emergency (A&E) attendances (Friday 3 p.m.–Sunday 3 p.m.), weekday A&E attendances (Monday–Friday 9 a.m.–5 p.m. each day), weekend ambulance call-outs (Friday 3 p.m.–Sunday 3 p.m.), weekday ambulance call-outs (Monday–Friday 9 a.m.–5 p.m. each day) to determine the effect on key crime indicators (street-level crime data) at the weekend (Friday 3 p.m.–Sunday 3 p.m.) and weekday (Monday–Friday 9 a.m.–5 p.m. each day) to determine the effect on key antisocial behaviour (ASB) indicators (police recorded calls for service were classified as ASB according to the National Standard for Incident Recording). Relating to the process evaluation: to explore policy context and variation in licensing practice, including any impact of devolution in GM to explore barriers and facilitators at key stages of the implementation of the intervention: recruitment of AHCs to initial training and cascade training, delivery of initial training and cascade training, use of skills beyond the training in AHC activity, retention of AHCs to explore responses to AHC training, modelling of health behaviours, perceptions of community cohesion and development to determine numbers of brief interventions applied and community awareness events organised/participated in to examine and quantify the amount and success of community involvement in licensing issues to determine whether there was a change in composite measures of alcohol availability. Relating to the economic evaluation: to identify set-up and running costs using a standardised costing exercise to resolve costs by sector (health, ambulance and police) before, during and after set-up to quantify benefits due to reduced hospital admissions, ambulance call-outs, A&E use, crime and ASB. Methods: Communities in Charge of Alcohol was a complex intervention already planned by the GMCA in 10 small local authority areas (~1600–5500 residents each) and was outside direct researcher control. Intervention areas were chosen by each local authority public health team as having high levels of alcohol harm in comparison to the rest of the local authority. All intervention areas were at the bottom of the deprivation index, in deprivation decile 1 or 2. Using a stepped-wedge design, researchers were able to randomise the order of roll-out of intervention areas to bring a quasi-experimental approach to the evaluation. Two additional evaluation designs were used in order to triangulate findings, namely comparison to matched controls and comparison to synthetic controls. Ethical approval was received from the University of Salford Research Ethics Committee on 17 May 2017 (reference number: HSR1617–135) and obtained from the University of Bristol on 16 May 2019 (reference number: 82762). Outcome evaluation data sources: Routinely collected data at the lower-layer super output area (LSOA) level for intervention areas was compared with control areas. Data sources were as follows: alcohol-related hospital admissions data – Public Health England (now Office for Health Improvement and Disparities) accident and emergency department attendance data – NHS Digital ambulance call-out data – North West Ambulance Service reported crime and ASB data – GM Police. Analysis spanned a 10-year period (7 years pre intervention and a maximum of 3 years post implementation), ending in January 2020. Data were analysed using log-rate growth models and time series analyses to quantify the effect of the CICA programme on key performance indicators. Process evaluation data sources: Pre-implementation phase document review of local Statements of Licensing Policy (n = 9), alcohol availability composite score of on- and off-licensed premises (n = 9 areas), roll-out preparatory meeting notes. Train-the-Trainer attendance registers by area (n = 5, representing 9 areas, attended by 48 lay participants and 25 professional participants). Cascade training attendance registers by area (n = 11, representing 7 areas, attended by 47 lay participants and 3 professional participants). Pre- and post-training questionnaires (n = 93 lay people, 98% response rate). Baseline interviews with stakeholders (n = 20) (initial implementation phase); interviews with lay volunteer AHCs (n = 5, representing 3 areas) within 3–6 months of initial training (implementation phase). Follow-up interviews (12 months) with stakeholders (n = 11, representing eight areas), licensing officers (n = 6, representing six areas) and lay volunteer AHCs (n = 7, representing four areas); follow-up questionnaires with AHCs (n = 11); focus groups with local residents (n = 3 groups, representing two areas, with a total of 26 participants). Economic evaluation data sources: Time and transportation costs incurred during project meetings aggregated from meeting minutes and stakeholder time/cost diaries. Invoices for the design, development and delivery of training packages and accreditation fees. Invoices for the qualification and assessment fees, time and miscellaneous (transportation, room hire, catering, printing costs). AHC time and costs aggregated from volunteer diaries and stakeholder time/cost diaries. Invoices for engagement materials (AUDIT-C scratchcards). Greater Manchester Combined Authority research team's (formerly New Economy) cost–benefit analysis (CBA) tool was populated using aggregated outcome evaluation data to resolve costs for each key performance indicator before, during and after CICA setup. Results: Nine out of 10 local authorities rolled out the CICA intervention on their given start date: seven areas completed a full year, carrying out cascade training in the first 12 months, two areas withdrew at 6 and 9 months and one area withdrew in the pre-implementation phase. There were 118 [interquartile range (IQR): 60–205] alcohol-related hospital admissions per month per pre-intervention LSOA , rising to 134 (IQR : 67–203) post intervention. Some outcomes had very small counts at the LSOA level; notably, there were only 2 (IQR : 1–3) weekend crimes per month pre-intervention and 4 (IQR : 2–6) post intervention. The primary, stepped-wedge analyses provide weak evidence of an average increase in alcohol-related hospital admissions following the implementation of CICA of about 13%, corresponding to about 20 admissions weekly, although the confidence interval was wide, −1.98 to 31.39, and not statistically significant (p~0.09), while the analysis that made use of local controls suggested a bigger effect, at 16.4% (7.33–26.16, p < 0.001). However, the other methods of analysis (national controls and counterfactuals) indicated much smaller effect sizes and confidence intervals, including unity: 3.42% (−4.56 to 12.07; p = 0.41) and 7.14% (−9.76 to 24.04; p = 0.41), respectively. The other quantitative outcomes (A&E admissions, or ambulance call-outs to the area, nor to reported crimes or reported ASB incidents) showed some were individual statistically significant effects (with some methods and some indicators), but these were more often not in favour of the intervention. Triangulation of three methods of analysis did not indicate any consistent differences between control and intervention areas. The pre-implementation phase was defined as the period leading up to the roll-out of the first Train-the-Trainer event. Several facilitating contextual factors were identified a priori. The total number of these factors in place at baseline correlated with numbers trained in the first year (Rs = 0.77, p = 0.01). Specifically, areas with a healthcare provider to co-ordinate the intervention (p = 0.02); a pool of other volunteers to recruit from (p = 0.02); a contract in place with a commissioned service (p = 0.02); and formal volunteer arrangements (p = 0.03) trained more AHCs. Across all nine areas, fewer volunteers were recruited than the anticipated target of 35 per area. In total, 123 AHCs were trained and gained a Royal Society for Public Health Level 2 qualification. Of these, 95 were lay volunteers from the intervention areas. The majority identified as white (70%), with ages ranging from 18 to 65+, and almost half aged between 41 and 60 (48%). Slightly more women volunteered compared to men (61%). Most AHCs self-reported being in the lower-risk drinking category (66% scored 0–4 on AUDIT-C). Post-training questionnaires suggested that volunteers felt more confident to talk about the harms associated with alcohol and give alcohol-related brief advice than they did pre training (91.4% compared with 79.6%, p < 0.001) and that they felt more confident to raise issues about venues selling alcohol (90.3% compared with 74.2% pre training, p < 0.001). Intervention areas that recorded AHC activity (n = 5) captured 1100 conversations, 251 AUDIT-Cs completed and 65 community events attended. Time/cost diaries suggested that AHCs spent on average 11 minutes having an informal brief advice conversation. Interviews with AHCs on self-reported activity were consistent with time/cost and reflective diaries: AHCs put into practice brief advice conversations more than community action to influence licensing. Interviews with stakeholders indicated several enabling factors to consider when rolling out and embedding an AHC intervention: a clear understanding of the place-based focus; commissioned provider services needing a clear understanding of own roles and the anticipated outcomes; and co-ordinators having the skills and capacity to support inexperienced volunteer groups. The importance of infrastructure was reflected in interviews, recognising that preparing the ground at a hyperlocal level takes time, needing to be well in advance of the formal implementation period. Recruitment strategies need to be multipronged, and stakeholders need to be prepared to provide a sustained period of support for new and existing champions. In the follow-up phase, 12 months post intervention, interviews with stakeholders revealed how the local co-ordinators' ability to operationalise and sustain CICA was significantly impacted by their lack of capacity to sustain the levels of support, as well as the complexity of skills required of the role. After 12 months, there was strong consistency in findings from follow-up interviews with stakeholders, AHCs and focus groups with members of the public. Communities in Charge of Alcohol's intended mechanism of action was to reduce alcohol-related harm through secondary prevention interventions; however perceptions of those most in need of an AHC conversation were 'problem drinkers' to signpost into tertiary interventions. Quality of local alcohol treatment services was considered to be poor, with multiple barriers to help and information seeking. Conclusions: To our knowledge, CICA is the first alcohol-focused champion role of its kind to be investigated and across multiple intervention sites. It is also the first evaluation of a health champion programme that uses methodological triangulation to strengthen inferences about effectiveness. There was evidence that lay people trained as AHCs were able to have conversations with members of their communities who were consuming alcohol at higher risk levels, demonstrating a level of skill and confidence that can sometimes be absent in health professionals. AHCs, their co-ordinators and the public valued the role. However, significant infrastructure is needed to support an intervention such as CICA , and time is needed to develop and embed a group of volunteers. Despite evidence (from the process evaluation) of the planned activity taking place at local level, we were not able to show that CICA was effective, nor was it cost-effective. There are likely to be two main reasons for this. Firstly, the number of champions trained was too small to have a sufficient number of brief advice conversations to generate any measurable effect at the area level of analysis. Moreover, brief interventions may not directly impact on primary health and crime outcomes at a population level. Secondly, the AHCs were less willing (and had less opportunity) to get involved with alcohol licensing decisions. Since licensing policies theoretically have an impact at an area level, this theoretically would have been more likely to generate a significant area-level effect. The evidence from this study is that communities continue to struggle to influence statutory processes that affect alcohol availability where they live, and further consideration of how to enable increased community engagement is necessary. Recommendations for future research (numbered in priority order): natural experiment evaluations should include methodological triangulation to guard against overinterpretation of spurious results investigate coproducing a community outcomes framework to measure reductions in alcohol harm evaluate whether rebalancing local licensing policy to be community-centred might increase community engagement in the local licensing decision-making process investigate the effectiveness of CICA in areas where indicators of alcohol harm are increasing but are not at the highest level of harm within the local authority a wider range of external contextual factors could be tested in the pre-implementation phase of a complex intervention, incorporating methods to combine factors into mean scores, to test relationships between process indicators and outcomes.

Nutrition in early life plays a key role in shaping an infant's future health. There is limited understanding of the perspectives of Vietnamese mothers with children under 24 months of age regarding breastmilk expression, donation and use. In this cross‐sectional study, an online survey was administered through two parenting social media communities to assess opinions on breastmilk expression, breastmilk donation including contributions from bereaved mothers and the use of donor human milk. A 4‐point Likert scale was used to evaluate respondents' opinions, and demographic and breastfeeding information was collected. Among 375 respondents, almost 30% had received breastmilk from another woman, either through direct breastfeeding (14.7%), expressed breastmilk (12.5%) or from a human milk bank (2.7%). In this survey of 375 mothers, 84.0% indicated they would store excess breastmilk, while 75.7% and 69.6% would donate to a human milk bank or another mother, respectively. When faced with insufficient breastmilk, 88.5% of mothers would seek ways to increase supply, whereas 23.8% considered using commercial milk formula. Regarding milk expression among the 375 mothers, 78.4% preferred electric pumps, compared to 48.6% for manual pumps and 45.9% for hand expression. Additionally, 80.5% of the 375 mothers would suggest donating stored milk to bereaved peers and 85.6% would suggest mothers with mild COVID‐19 to continue breastfeeding with precautions. These findings indicate that this sample has positive views on breastfeeding, breastmilk donation and the use of donor human milk. [ABSTRACT FROM AUTHOR]

Media campaigns can spur conservation action but may alienate local communities. Transforming such action into self‐sustaining community‐based conservation involves effective governance that rapidly integrates knowledge of resource dynamics, establishes flexible institutions, and fosters multilevel networks. This study examines the emergence of community‐based conservation in response to a media campaign to protect migratory Amur falcons, illustrating shifts in governance and power dynamics that enabled local community ownership. Although conservation developed in the absence of an adequate preparation phase, external engagement, incentives, and recognition of local institutions' legitimacy were instrumental in fostering collective action. This research showcases how community‐based conservation initiatives can be triggered by external social pressure but also how the long‐term sustainability relies on effective governance that respects local institutions and employs cooperative strategies to build trust and foster ownership among local communities.

This article aims at reconstructing the representations of the 2022 January crisis developed by Kazakhstani political analysts via social media. The research methodology seeks to combine quantitative and qualitative methods by assessing these representations by use of critical discourse analysis of social media posts by Kazakhstani political analysts extracted and processed by the use of API and PolyAnalysts based on marker words. The research significance lies in the unique situation of regime instability potentially providing the expert community with the chance to speak up openly. However, it is concluded that most analysts reproduced the official discourse that is in line with the discourses developed in non-democratic context. Thus, the dominant expert discourse of the January crisis is rather homogenous and relies on the dichotomies of "the old" versus "the new" as well as "the weak" versus "the strong." As a result, the general picture by Kazakhstani political analysts looks more like a political myth about the birth of a "new Kazakhstan" than a reconstruction of the causes, actors and consequences of the January crisis. It implies that the expert community prefers controlled evolution of the state regime rather than grass roots initiated changes. [ABSTRACT FROM AUTHOR]

Spatial counterfactuals are gaining attention to address the lack of robust flood frequency analysis in small catchments. However, the credibility of counterfactual scenarios decreases with the distance rain fields are shifted across space. We limit that distance by a local counterfactual search design, and compare the corresponding scenarios to recently published results from large spatial shifts. We then put all scenarios in context with 200-year return levels, and with flood peaks simulated for the June 2024 flood event in southern Germany. We conclude that local counterfactuals scenarios are transparent and credible, and could complement the anticipation of low probability events. [ABSTRACT FROM AUTHOR]

Chronic Otitis Media (COM) is defined as long term inflammation and colonization with pathogenic bacteria due to a defect or retraction of the tympanic membrane. Surgical interventions are often augmented by antibiotic resistance development and therefore, off-label treatment using the natural drug 1,8-Cineol was carried out. All COM patients underwent antibiotic therapy and middle ear surgery and developed antibiotic resistances. Microbiological investigations from the auditory canal and stool samples were performed in correlation with the clinical course. Therapy of COM patients with 1,8-Cineol revealed a clear reduction of inflammatory microbes P. aeruginosa and Proteus mirabilis in ear samples as well as intestinal Prevotella copri, which was associated with an improved clinical outcome in certain individuals. The present off-label study revealed manifold anti-inflammatory effects of the natural monoterpene 1,8-Cineol in Otitis media patients. A better understanding of the underlying mechanisms will improve the current treatment options and possible forms of application of this natural drug. [ABSTRACT FROM AUTHOR]

Background: Against the backdrop of the global public health crisis, the COVID-19 pandemic has exposed significant disparities in the supply and demand of risk information related to public health crises, posing severe challenges to risk governance in megacities. Shanghai, China, introduced community WeChat groups for community communication, effectively facilitating the dissemination and response of grassroots information and providing a new path for interactive governance in the community. Methods: This study collected 1006 questionnaires from residents of 350 communities in Shanghai through an online survey between June 10 and July 10, 2022. Multiple linear regression analysis was conducted to examine the impact of different participants (including the community, core residents, and the combined community and core residents) on community risk communication, perceived communication quality, and dissemination themes related to COVID-19 on community communication satisfaction. Additionally, in-depth interviews were conducted with 20 core residents from different types of communities, focusing on the specific methods of risk communication through community WeChat groups and their ability to disseminate information, respond to, and solve problems. Results: Perceived information coverage and perceived response efficiency are significantly positively correlated with communication satisfaction. Notably, the speed of community information response has the greatest impact on communication satisfaction. Regarding COVID-19-related information dissemination themes, "community outbreaks, supplies, nucleic acids, outbreak prevention measures, and scientific content" all have a significant impact on communication effectiveness, with "nucleic acid testing information" having the greatest impact. Although the statistical data indicate that the participation of core residents in risk communication does not significantly affect communication satisfaction, it seems to be related to the size of the community, and the interview results further validate this conclusion. Conclusion: In the future, grassroots communities should consider the affordances of social media, recognize the significant correlation between risk communication and grassroots trust, and formulate more detailed and targeted risk communication strategies. In particular, incorporating core residents into "semiformal" grassroots organizations can improve community service quality, thereby enhancing community resilience in the face of public health emergencies.

The 'watchdog' model has created a journalism culture that is too adversarial and creates conflicts rather than helping to solve today's problems/conflicts. The panellists assess new journalism paradigms in the Asia-Pacific region where the media is able to make powerful players to account for facilitating the development needs of communities, especially those in the margins of society. A challenge for contemporary journalism schools is to address such models in a global context of 'development rights' with the UN's Sustainable Development Goals as a benchmark. In the Pacific Islands context, journalists face a challenging news reporting terrain on their news beats, especially in the Melanesian countries of Fiji, Papua New Guinea, Solomon Islands and Vanuatu. Besides dealing with political instability, coups, civilian unrest and complex developmental issues, journalists must contend with hostile governments and draconian media legislation. The talents, idealism and storytelling skills of Pacific journalists can be cultivated and strengthened to produce independent platforms and models of journalism that challenge the status quo. Examples of this campus strategy include Radio Pasifik, Wansolwara, Pacific Scoop and Asia Pacific Report. [ABSTRACT FROM AUTHOR]

Children's everyday lives beyond school need to be considered holistically, in a way which moves beyond time use. In this article we draw on our adaptation of Sarah Pink's (e.g. 2012) video re-enactment methodology for considering children's out-ofschool lifeworlds with Year 4 children (9 and 10 years old) in the global cities of Hong Kong, Melbourne, and Singapore. The data presented and discussed here was part of a larger Global Childhoods Project with children in the three global cities of Melbourne, Hong Kong, and Singapore. We use video re-enactment methodology to 'think with', to open up lines of inquiry and create conversations about children's lives in and between the cities. Through these we consider the specifics of each city context, as well as socioeconomic and sociocultural contexts and factors that may impact differently on children's everyday lifeworlds out-of-school within the same city. In order to focus the scope of the article, we consider family routines, enrichment activities and local communities, as aspects that we find useful to reflect on when exploring what children's lives look like, in and across locations. We focus on these as we are interested in how they might add to the complexities of thinking about children in each location. We move between thinking about the re-enactments themselves and broader literature to explore children's out-of-school lifeworlds in the three cities, painting a picture of children's lives and considering the contexts which make particular activities and practices possible and desirable.

Satellite edge computing (SEC) plays an increasing role in earth observation, due to its global coverage and low-latency computing service. In SEC, it is pivotal to offload diverse observation-data-processing tasks to the appropriate satellites. Nevertheless, due to the sparse intersatellite link (ISL) connections, it is hard to gather complete information from all satellites. Moreover, the dynamic arriving tasks will also influence the obtained offloading assignment. Therefore, one daunting challenge in SEC is achieving optimal offloading assignments with consideration of the dynamic delay-sensitive tasks. In this paper, we formulate task offloading in SEC with delay-sensitive tasks as a mixed-integer linear programming problem, aiming to minimize the weighted sum of deadline violations and energy consumption. Due to the limited ISLs, we propose a fully-decentralized method, called the PI-based task offloading (PITO) algorithm. The PITO operates on each satellite in parallel and only relies on local communication via ISLs. Tasks can be directly offloaded on board without depending on any central server. To further handle the dynamic arriving tasks, we propose a re-offloading mechanism based on the match-up strategy, which reduces the tasks involved and avoids unnecessary insertion attempts by pruning. Finally, extensive experiments demonstrate that PITO outperforms state-of-the-art algorithms when solving task offloading in SEC, and the proposed re-offloading mechanism is significantly more efficient than existing methods.

Hate crimes are widespread in Hong Kong society. Foreign domestic helpers working in Hong Kong also experience unfair agenda-setting by the media due to their dual economic and social disadvantages, and the media tries to portray them in a hostile social role. At the same time, the media creates negative social images of minority groups through news coverage, which leads to an increase in social hate crimes against them. This study used WiseSearch, a Chinese newspaper collection and analysis platform, to explore how Hong Kong news media use news themes and content to create a negative image of Hong Kong foreign domestic helpers in order to understand the media origins of hate crimes against Hong Kong foreign domestic helpers. Ultimately, the study found that local news media in Hong Kong are more inclined to cover the legal disputes of foreign domestic helpers in the agenda-setting process. In addition, they are more likely to associate foreign domestic helpers with "fear" rather than "rest assured." The study also found that because of the news value orientation, Hong Kong media tended to treat foreign domestic helpers as outsiders and less sympathetically when writing news stories.

While scholars have long recognized the central importance of the cross within Syriac-speaking Christian communities in late antique Mesopotamia, the question of how physical crosses functioned as aids for prayer has only recently begun to be explored. The present article addresses this question with respect to East Syrian monastic communities in seventh-century Mesopotamia, focusing on the context of the monastic cell. Bringing together accounts of cross-directed prayer in Syriac monastic literature with archaeological evidence for crosses from the region, the article concludes that physical crosses played an important role as mediating devices of divine presence that were both always at hand and the frequent objects of monastics' sensorial attention. These conclusions are subsequently discussed through the lens of recent research from the field of new media studies toward the goal of understanding how cross-directed prayer may have served to bridge monastic spirituality and sociality in Mesopotamia.

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.

The Local Media for Democracy (LM4D) project is the first project that explores news deserts in Europe comprehensively. Its final report highlighted challenges and opportunities for local and community media and identified the level of risk of news deserts in the 27 European Union (EU) Member States. As a pilot project, however, its results are still preliminary and open to evaluation, and, thus, they require further discussion and corroboration. Drawing from these results, and applying a multidisciplinary approach, we extrapolated research directions for the study of news deserts in the EU. By cross-analyzing data from the LM4D dataset with other datasets, we provide a preliminary analysis of three promising lines of research: (1) the relationship between public service media quality and news deserts, (2) news deserts and the spread of disinformation, and (3) social media usage and news desertification. We conclude by pointing out the limitations of this preliminary analysis and opportunities for further research on news deserts in the EU. [ABSTRACT FROM AUTHOR]

This study examines the role of local media in fostering a sense of community belonging among readers in the Ecuadorian context, focusing on how geographical coverage, news sources, and covered themes reinforce community identity. Through content analysis of 17 local media outlets and 6356 news pieces, we investigate how these elements cohesively contribute to the construction of an interconnected community. The findings indicate that predominantly local and regional coverage, along with reliance on primary sources within the community and the prevalence of topics related to politics, sports, and culture, play pivotal roles in creating a shared community fabric. By contextualizing the importance of "glocalization" in journalism, the study demonstrates how local media act as a mirror to community realities and aspirations, promoting a sense of intersubjectivity, adaptability, and civic engagement. This work underscores the critical importance of local media in representing the diversity of reality, facilitating civic participation, and strengthening the social fabric within the local context.

Background: Women living in high-quality healthcare systems are more likely to use oral contraceptives at some point in their lives. Research findings have sparked controversial discussions about contraception in the scientific community and the media, potentially leading to higher rates of method discontinuation. Understanding the underlying motives for method discontinuation is crucial for reproductive health equity and future programming interventions. To address this question, this study aims to explore women's experiences of oral contraceptive use and discontinuation on YouTube. Methods: A concurrent explanatory mixed-methods design was used to conduct content analysis of German YouTube videos. The information from 175 videos of 158 individuals was extracted through quantitative descriptive content analysis. Twenty-one individuals were included in the qualitative content analysis. Findings: The body was a recurring theme in the pill biographies. Women described, for example, bodily sensations as reasons for taking and stopping the pill. They also described positive and negative side effects while taking the pill and after stopping. The most common side effects of taking the pill mentioned by YouTubers were mood swings (76/158), weight gain (45/158), headaches (33/158), and depressed mood (45/158). The symptoms after discontinuation reported most were facial skin impurities (108/158), decreased mood swings (47/158), hair loss (42/158), and weight loss (36/158). Overall, women overwhelmingly rated their discontinuation experience as positive (87/91). Conclusions: The study identified key symptoms of oral contraceptive initiation and discontinuation by portraying the experiences of female YouTubers, adding valuable insights to the understanding of method initiation and discontinuation. Further research is needed to explore women's personal experiences with method discontinuation beyond the YouTube platform. [ABSTRACT FROM AUTHOR]

Self-assembly formation is a key research topic for realizing practical applications in swarm robotics. Due to its inherent complexity, designing high-performance self-assembly formation strategies and proposing corresponding macroscopic models remain formidable challenges and present an open research frontier. Taking inspiration from crystallization, this paper introduces a distributed self-assembly formation strategy by defining free, moving, growing, and solid states for robots. Robots in these states can spontaneously organize into user-specified two-dimensional shape formations with lattice structures through local interactions and communications. To address the challenges posed by complex spatial structures in modeling a macroscopic model, this work introduces the structural features estimation method. Subsequently, a corresponding non-spatial macroscopic model is developed to predict and analyze the self-assembly behavior, employing the proposed estimation method and a stock and flow diagram. Real-robot experiments and simulations validate the flexibility, scalability, and high efficiency of the proposed self-assembly formation strategy. Moreover, extensive experimental and simulation results demonstrate the model's accuracy in predicting the self-assembly process under different conditions. Model-based analysis indicates that the proposed self-assembly formation strategy can fully utilize the performance of individual robots and exhibits strong self-stability. [ABSTRACT FROM AUTHOR]

Water body extraction from high-resolution remote sensing images often results in incomplete and discontinuous extraction results due to factors such as complex types of ground objects and narrow rivers. To address these challenges comprehensively, combined with the spectral and texture characteristics of the water body itself, this paper proposed an innovative method for water body extraction and optimization in high-resolution remote sensing images that combines global features and local interconnection. The proposed method integrates the intrinsic spectral and textural features of water bodies, adopting a strategy of initial extraction followed by optimization and skillfully blending global and local communication features. Firstly, linear tributaries are recognized based on the initial water extraction results using multiscale Frangi filtering and the OTSU segmentation algorithm and river replenishment is applied to these linear features, resulting in preliminary optimization results. Then, a locally interconnected disconnection continuation algorithm is introduced to connect disjointed segments in the preliminary optimization results ingeniously. The final stage involves the extraction of water body segments using K-means clustering, and topology inspection and spectral inspection are performed with the accurate optimization results to achieve verification and screening of blocky water bodies. Then, rigorous checks are conducted to validate and filter block-shaped water bodies, ensuring the precision of the extraction results. Experimental results validate the outstanding performance of this method, particularly in the extraction of small tributaries, resulting in a substantial improvement in optimization accuracy. Introducing the disconnection continuation algorithm enhances the completeness of river extraction and fortifies the overall robustness of water body extraction. Comparative analysis with other methods reveals an overall accuracy improvement of 1.04% and 1.50%, along with an increase in comprehensive value by 5.84% and 8.28%, respectively. It can be used as a means to effectively improve the post-processing of water body optimization and improve the integrity and accuracy of water body extraction. [ABSTRACT FROM AUTHOR]

In the national strike of June 2022 in Ecuador, the media was the scene of confrontational discourses regarding the mobilization. The community media, unlike the private media, allied themselves with the demonstrators' positions. This theoretical-analytical reflection addresses two particularities that were evidenced in the practices of community media, the media-space relationship and the configuration of discourses, in order to evaluate the power of these media to sustain different and more responsible communication proposals, especially in contexts of high social conflict.

The significance of community structure in complex networks, such as social, biological, and online networks, has been widely recognized. Detecting communities in social media networks typically relies on two sources of information: the network's topological structure and node attributes. Incorporating rich node content attribute information poses both flexibility and challenges for community detection. Traditional approaches either focus on mining one information source or linearly combining results from both sources, which fails to effectively fuse the information. This paper introduces a practical collaborative learning approach that explores the multi-dimensional attribute characteristics of nodes to facilitate community division. By leveraging graphical matrix decomposition, the proposed algorithm, CDGMF, improves the effectiveness and robustness of community detection. Experimental results demonstrate the method's ability to effectively utilize node attribute information for guiding community detection, resulting in higher-quality community divisions.

Regional and local media outlets have much more credibility than news organizations placed at a national level, according to polls. In a context fueled by the spread of disinformation, audiences seem to trust close journalistic sources, while national and international leaders are seen as polarized. However, local journalism has few resources for fact checking. In this context, we explore some of the strategies developed by local news organizations to avoid the proliferation of fake news. This study uses a multiple-case study on four local media outlets from similar media systems (Spain and Portugal) as a qualitative research strategy. Drawing upon in-depth interviews with local journalists and secondary data analysis, we examine how these media outlets deal with fake news, shedding light on internal fact-checking resources and other original strategies applied. From our interviews, their journalists are aware of the problem, asking for more training; whereas their organizations have different approaches to the digital platforms where most of disinformation circulates. These findings contribute to the scant literature on the role of the local field in disinformation, arguing that the social mission of local journalism may be a guarantee against fake news if their journalists are trained.

As network structure of virtual communities related to suicide and school shooting still remains unaddressed in scientific literature, we employed basic demographics analysis and social network analysis (SNA) to show common features, as well as distinct facets in the communities' structure and their followers' network. Open and publicly accessible data of over 16,000 user accounts were collected with a social media monitoring system. Results showed that adolescents and young adults were the main audience of suicide-related and school shooting fan communities. List of blocked virtual groups related to school shooting was more extensive than that of suicide, which indicates a high radicalization degree of school shooting virtual groups. The homogeneity of followers' interests was more typical for subscribers of suicide-related communities. A social network analysis showed that followers of school shooting virtual groups were closely interconnected with their peers, and their network was monolithic, while followers of suicide-related virtual groups were fragmented into numerous communities, so presence of a giant connected component in their network can be questioned. We consider our results highly relevant for better understanding the network aspects of virtual information existence, harmful information spreading, and its potential impact on society.

Pancreatic ductal adenocarcinoma (PDAC), a lethal disease, requires a grasp of its biology for effective therapies. Exosomes, implicated in cancer, are poorly understood in living systems. Here we use the genetically engineered mouse model (ExoBow) to map the spatiotemporal distribution of exosomes from healthy and PDAC pancreas in vivo to determine their biological significance. We show that, within the PDAC microenvironment, cancer cells establish preferential communication routes through exosomes with cancer associated fibroblasts and endothelial cells. The latter being a conserved event in the healthy pancreas. Inhibiting exosomes secretion in both scenarios enhances angiogenesis, underscoring their contribution to vascularization and to cancer. Inter-organ communication is significantly increased in PDAC with specific organs as most frequent targets of exosomes communication occurring in health with the thymus, bone-marrow, brain, and intestines, and in PDAC with the kidneys, lungs and thymus. In sum, we find that exosomes mediate an organized intra- and inter- pancreas communication network with modulatory effects in vivo. The behavior of exosomes in vivo is not completely elucidated. Here the authors develop a genetically engineered mouse model (ExoBow) to trace the distribution of exosomes, showing local and inter-organ communication networks, either specific or shared between healthy pancreas and pancreatic ductal adenocarcinoma.

Universities globally utilise social media platforms to disseminate information to prospective students. However there's a scarcity of research regarding the role of social media in promoting universities as international education hubs, especially in Asia. This study aims to investigate the impact of social media in promoting Asian universities, focusing on the preferences and behaviours of prospective undergraduate students from Malaysia and Indonesia. A qualitative research approach was employed, involving the recruitment of 12 undergraduate students from both countries. Data collection was conducted through online, in-depth, and semi-structured interviews. The majority of participants rely on social media platforms to gather information about potential universities and courses, citing ease of navigation and appeal compared to traditional websites and other platforms. However, universities demonstrate a lack of engagement with users, hindering the acquisition of comprehensive information about the institution. These findings offer valuable insights for universities to understand the information and social media elements that prospective students commonly seek on social media platforms. Additionally, they provide guidance on effective strategies for engaging with and recruiting students. Ultimately, this research may assist universities in better promoting themselves as international education institutions, particularly in the Asian context. [ABSTRACT FROM AUTHOR]

Current epidemics in the biological and social domains are challenging the standard assumptions of mathematical contagion models. Chief among them are the complex patterns of transmission caused by heterogeneous group sizes and infection risk varying by orders of magnitude in different settings, like indoor versus outdoor gatherings in the COVID-19 pandemic or different moderation practices in social media communities. However, quantifying these heterogeneous levels of risk is difficult, and most models typically ignore them. Here, we include these features in an epidemic model on weighted hypergraphs to capture group-specific transmission rates. We study analytically the consequences of ignoring the heterogeneous transmissibility and find an induced superlinear infection rate during the emergence of a new outbreak, even though the underlying mechanism is a simple, linear contagion. The dynamics produced at the individual and group levels are therefore more similar to complex, nonlinear contagions, thus blurring the line between simple and complex contagions in realistic settings. We support this claim by introducing a Bayesian inference framework to quantify the nonlinearity of contagion processes. We show that simple contagions on real weighted hypergraphs are systematically biased toward the superlinear regime if the heterogeneity of the weights is ignored, greatly increasing the risk of erroneous classification as complex contagions. Our results provide an important cautionary tale for the challenging task of inferring transmission mechanisms from incidence data. Yet, it also paves the way for effective models that capture complex features of epidemics through nonlinear infection rates. [ABSTRACT FROM AUTHOR]

Guinea‐Bissau, an important regional biodiversity hotspot in West Africa, faces the challenge of raising awareness among the general public about the significance of natural resources for rural communities' survival and the need for biodiversity conservation. This knowledge gap hinders conservation efforts as initiatives are deemed irrelevant or unnecessary. A climate of political vulnerability, financial uncertainty and threats to media freedom are further obstacles to conservation biology. Researchers lack established communication platforms for academic dissemination. In this paper, we introduce the initiative News for Nature/PRIMACTION (2020–2022), which aimed to establish a communication channel between researchers and media agents. The project had two primary objectives: firstly, to raise awareness among the Guinea‐Bissau society about the importance of national biodiversity and conservation challenges; and secondly, to enhance the capacity of specific communicators and opinion makers. The project had several important outputs, including: i) a bi‐monthly newspaper section focused on "biodiversity conservation in Guinea‐Bissau", ii) three radio‐theatre episodes performed by a well‐known group and broadcasted nationally, iii) one song composed and sung by famous musicians, with an introduction by Jane Goodall, and iv) a website providing technical resources for journalists covering biodiversity and conservation news. Collaborators mentioned the lack of logistical conditions for traveling in the country as a major impediment in reporting conservation‐related news. We emphasize the significance of establishing direct contact and articulation between researchers and local media to promote conservation research in West African countries. In countries where science communication and environmental education outreach are not well‐established, it is crucial to bridge the challenges faced by the communities in different regions of the same country. This is especially urgent in cases where such challenges are significant. [ABSTRACT FROM AUTHOR]

This paper investigates the use of social media in public administration by applying a public relations approach. Public relations (PR) offer an integrative theoretical and practical strategic framework in the analysis and implementation of communication in public administration, which brings essential contributions to the functioning of democracy. Changes imposed by social media generated new communication practices for governance and public administration services, offering interesting research topics. The present study is substantiated by the conceptual coordinates of modern PR, excellence theory, and its measurement principles. It discusses government PR as a particular area in the field. It reviews the methodology and findings of studies conducted in Romania on the subject of government PR and the use of recent technology in central and local government communication. The research is based on a content analysis investigating the social media PR on three online platforms, Facebook, Instagram, and YouTube, for five municipalities in Romania, Bucharest, Cluj-Napoca, Constanța, Iași, and Timișoara. The study offers a descriptive picture of the current Romanian realities and fosters government social media strategic communication analysis, by exemplifying the use of a methodological investigation framework, based on modern concepts of the field of PR.

This research seeks to delve into the dynamics of participation within news platforms curated by non-professional journalists residing in inland Portugal. Through an exploratory study, two initiatives originating from communities located in the country's inland areas are analysed: Vela Notícias, in the Centre region, and Jornal da Aldeia, in the Alentejo region. These initiatives serve as empirical objects illustrating a phenomenon that reflects the shift away from traditional media, the community's eagerness to disseminate locally pertinent knowledge, and the citizens' yearning for social and cultural representation. Both initiatives have emerged in ageing and sparsely populated regions, with fewer than 1,000 inhabitants, according to the 2021 Census (Instituto Nacional de Estatística, 2021). To understand and address these concerns, alongside a thorough review of pertinent literature, semi-structured interviews were conducted as a methodological approach involving participants engaged in information production for the two community media outlets. The significance of this study lies in unravelling the intricacies of proximity communication dynamics spearheaded by non-journalist citizens. The residents of both parishes actively contribute to content creation, topic selection, editing, and distribution of the newspapers. Production operates outside the norms of journalistic selection, filtering, and hierarchy. Nevertheless, interviewees exhibit keen interest and confidence in the published information. The motivation for participation stems from a desire to share common values and cultural connections, fostering a sense of belonging and social responsibility. [ABSTRACT FROM AUTHOR]

The article analyses the violations of the right to communication suffered by community journalists in the last three elections based on the results of a survey covering the five regions of Brazil. Through bibliographical and documentary review, it presents an overview of the situation of journalists' safety, focusing on the specific vulnerabilities that community media face in local news production, both in offline and online environments. The analysis of the results points to a scenario of hostility and vulnerability in community journalism and provides elements for mapping the factors that influence the safety of community journalists in Brazil.

The crisis around the operation of the Turów coal mine and its impact on cross-border relations in the Polish-Czech borderlands is examined in this article. The genesis of the international dispute and its course is analysed on the basis of international relations and border studies theories. Moreover, the specific cross-border relations and asymmetries in the area are studied. Then, the authors discuss the methodology and results of the research through questionnaires and formulate conclusions drawn from the research conducted by the Polish-Czech research team in 2022. The results prove that the nearly two-year Polish-Czech dispute over the Turów mine hurt the cross-border activity of the inhabitants of the Polish-Czech border. Despite alarming media news, this impact was weak and short-lived. It ultimately did not significantly impact the cross-border integration of the inhabitants or cause a deterioration of relations between the Polish and Czech sides of the Euroregion Neisse-Nisa-Nysa. The crisis was caused by the lack of adequate communication between local governments from Poland and the Czech Republic and insufficient commitment from the local and regional authorities. Another cause was the poor integration of residents in the border area, although the cross-border cooperation epitomised by the Euroregion Neisse-Nisa-Nysa is not poorly rated.

Tourism development allows the enhancement of the heritage of local cultural resources, expressing the territorial potential. The Systematic Literature Review shown in this paper highlight the relationship between "cultural heritage" and "tourism". The current state of the art and the specific relationships between the contents of the selected publications demonstrate that tourism is an indispensable tool in local communication and cultural promotion policies and strategies. The qualitative results allow the identification of cultural tourism geographies that coincide with four thematic clusters not evident in advance. [ABSTRACT FROM AUTHOR]

Highlighting the local impacts of climate change has the potential to increase the public's awareness of and engagement with climate change. However, information about local impacts is only effective when delivered by trusted sources such as copartisan political leaders. Is information about climate change conveyed by local media sources similarly beneficial? We argue that local media are well positioned to communicate the local implications of climate change, thereby enhancing the public's risk perceptions of climate change and willingness to take climate action. We further hypothesize that climate coverage by local media, the media type that is more trusted across party lines, will have a significant influence on Republicans' climate attitudes. Using the case of Louisiana, we first demonstrate that local and national newspapers cover climate change in substantially different ways, with local media more consistently focused on local impacts. Our survey experiment of Louisiana residents reveals that Republicans viewed the coverage of a hurricane in the region more positively when it came from a local newspaper rather than a national newspaper. Furthermore, local newspapers' climate coverage increased Republicans' willingness to take action to mitigate climate change. These results provide insights into the effective communication of climate change to the public and the role of local media in mitigating partisan polarization. [ABSTRACT FROM AUTHOR]

The Preston type material removal model is a popular means to predict the material removal distribution across a workpiece surface that has been subjected to an abrasive flow machining (AFM) process. The Preston equation includes an empirically derived coefficient, k. The data necessary to derive it are taken from a calibration test using a specific media type and specific workpiece material. The premise of this methodology is that, once the k coefficient is derived, the model may be used to predict the material removal distribution for any AFM application using the same media type and workpiece material. This investigation was carried out to explore the validity of this assumption. Through experimentation, it was discovered that media temperature within the active machining zone can continuously increase well above the media temperature control setting in the AFM machine. Furthermore, this temperature increase can significantly affect the machining process. Likewise, if not accounted for, it will significantly degrade the prediction of local media flow variables that are needed for material removal prediction, along with k. It was also determined that even if dynamic temperature change is accounted for, k is not constant, but instead sensitive to local pressure and process duration. Lastly, it was determined that material removal is more accurately predicted through the use of a power law equation involving local values of media pressure, velocity, viscosity, and shear stress.

Sense of place is a fundamental aspect of cultural heritage conservation and management, as it plays an important role in understanding the connection between individuals and the places they inhabit. This study aims to provide heritage managers and scholars with upto-date insights into the importance of a sense of place in maintaining cultural heritage. The main objectives of this research are to explore whether a sense of place's role in cultural heritage research has been adequately investigated and to assess the sense of place potential in cultural heritage conservation. We conducted a systematic literature review of 42 articles to achieve these goals. Through thematic analysis, this study reveals a sense of place's impact on various aspects of cultural heritage conservation. From the results, six prominent themes emerged, highlighting that a sense of place is a key determinant in the effectiveness of cultural heritage management initiatives. Based on these findings, authors advocate for enhanced collaboration between the government and local communities, acknowledging the importance of heritage tourism and reinforcing policies for cultural heritage conservation to bolster the sense of place. In future research, examining a sense of place can expand to interdisciplinary intersections, quantitative studies, cross national comparative research, and the exploration of the role of technology in augmenting both the sense of place and cultural heritage conservation.

Purpose: This study aims to contribute to the ongoing discussion of how consumers approach shopping directly via social media by explicating decisions related to trust on social media and how various types of electronic word of mouth (eWOM; ratings and reviews, recommendations and referrals and social media communities) contribute to these decisions. Design/methodology/approach: A total of 198 respondents with experience shopping directly via social media were instructed to select the platform on which they had the most shopping experience (Facebook, Instagram, TikTok, Pinterest, etc.) to answer relevant survey questions. Structural equation modeling (SEM) was used for analyzing the results. Findings: Findings reveal that eWOM provided by strong ties (recommendations and referrals; social media communities) is superior to weak ties (ratings and reviews). Surprisingly, ratings and reviews do not significantly relate to trust in the retailer, suggesting that this information may be necessary but not sufficient for trusting retailers on social media. Originality/value: This research distinguishes trust decisions related to shopping on social media and clarifies how each type of eWOM uniquely influences trust in the retailer by using tie strength theory.

Beginning January of 2020, COVID-19 cases detected in Arctic countries triggered government policy responses to stop transmission and limit caseloads beneath levels that would overwhelm existing healthcare systems. This review details the various restrictions, health mandates, and transmission mitigation strategies imposed by governments in eight Arctic countries (the United States, Canada, Greenland, Norway, Finland, Sweden, Iceland, and Russia) during the first year of the COVID-19 pandemic, through 31 January 2021s31 January 2021. We highlight formal protocols and informal initiatives adopted by local communities in each country, beyond what was mandated by regional or national governments. This review documents travel restrictions, communications, testing strategies, and use of health technology to track and monitor COVID-19 cases. We provide geographical and sociocultural background and draw on local media and communications to contextualise the impact of COVID-19 emergence and prevention measures in Indigenous communities in the Arctic. Countries saw varied case rates associated with local protocols, governance, and population. Still, almost all regions maintained low COVID-19 case rates until November of 2020. This review was produced as part of an international collaboration to identify community-driven, evidence-based promising practices and recommendations to inform pan-Arctic collaboration and decision making in public health during global emergencies.
