Introduction Municipalities play a critical role in shaping built environments that support active living, yet little is known about how municipal officials interpret these agendas, implement them or balance them with competing policy demands. This study explores how municipal officials in urban Thailand perceive and implement built environment strategies, manage constraints and identify opportunities to promote active living. Methods We conducted a qualitative study using semistructured interviews with 27 informants: eight elected officials, 15 senior appointed officials and four technical staff from seven municipalities across Thailand. Municipalities were purposively selected to reflect variation in geography across seven regions and administrative levels, including metropolitan, city and town contexts. Thematic analysis combined deductive coding based on policy-related topics such as roles, coordination and governance challenges with inductive coding to identify emergent themes. Results Three themes emerged. First, municipal officials commonly viewed the built environment through a recreational lens, prioritising parks and leisure spaces for their visibility, popularity and alignment with community expectations. Planning was influenced by leadership preferences and external models. Second, implementation was hindered by institutional fragmentation, overlapping mandates, weak cross-sector coordination and contextual factors such as complex land use, unregulated street activity, motorcycle-dominated mobility and political sensitivities. These challenges were more pronounced in smaller municipalities with limited technical capacity. Third, enabling factors included strengthened decentralisation, national incentives (eg, additional floor area near transit hubs), partnerships to repurpose underused spaces, digital tools such as mobile apps for responsive service delivery, adaptive leadership for public communication and leveraging local assets to support inclusive, context-sensitive development. Conclusion In urban Thailand, municipal strategies for active living continue to emphasise recreation over mobility. Implementation remains constrained by institutional and contextual challenges. Advancing more inclusive and responsive environments will require stronger governance, supported by decentralisation, community partnerships, digital tools, local assets and adaptive leadership.

Edge devices have limited resources, which inevitably leads to situations where stream processing services cannot satisfy their needs. While existing autoscaling mechanisms focus entirely on resource scaling, Edge devices require alternative ways to sustain the Service Level Objectives (SLOs) of competing services. To address these issues, we introduce a Multi-dimensional Autoscaling Platform (MUDAP) that supports fine-grained vertical scaling across both service- and resource-level dimensions. MUDAP supports service-specific scaling tailored to available parameters, e.g., scale data quality or model size for a particular service. To optimize the execution across services, we present a scaling agent based on Regression Analysis of Structural Knowledge (RASK). The RASK agent efficiently explores the solution space and learns a continuous regression model of the processing environment for inferring optimal scaling actions. We compared our approach with two autoscalers, the Kubernetes VPA and a reinforcement learning agent, for scaling up to 9 services on a single Edge device. Our results showed that RASK can infer an accurate regression model in merely 20 iterations (i.e., observe 200s of processing). By increasingly adding elasticity dimensions, RASK sustained the highest request load with 28% less SLO violations, compared to baselines.

5G specifications promise a common and flexible-enough network infrastructure capable of satisfying diverse requirements of both current and future use cases. Two service types standardized in 5G are eMBB, without stringent delay guarantee, and URLLC, with stringent delay guarantee. We focus on a use case where data timeliness is the relevant quality parameter. We provide an economic rationale for the support of data-based services, that is, from the point of view of the profits attained by the service providers and operators (SP). More specifically, we focus on data-based services the quality of which is related to the Age of Information, and we assess two alternatives for the support of this sort of services by means of a 5G network: one that is based on the eMBB service type, and one that is based on the URLLC service type. These assessment is conducted in a duopoly scenario. We conclude that URLLC support provides a competitive advantage to an SP against a competitor SP that supports its service offering on eMBB. And that there is a slightly better situation for the users when the URLLC QoS constraint is stringent.

In the ever-changing 21st century, a new generation has emerged that is ready to change the way we see and interact with others. The aim of this article is to observe the intricacies and complexities of Generation Z's personal relationships. To study this particular generation in more detail, we conducted a quantitative study, a survey to be precise, and the results were interesting. We were able to observe how much value these people place on their personal relationships, how they maintain them, how they engage with each other and how important these relationships are to them personally. Personal connections were highly valued by the majority of participants and had a major impact on their lives. Most of them enjoy meaningful relationships and are satisfied with their circumstances. Despite the fact that this generation is chronically online, it seems to be much easier for most of them to build relationships offline, face-to-face. The ability to express ourselves better in person, the fact that we are social creatures, and the fact that real friendships can form and last much longer are just some of the reasons why some people find it easier to build relationships offline.

With the aim of investigating shared leadership in conjunction with team members’ proactive behaviours, the main focus of this study is on the role of job crafting and knowledge sharing, as well as psychological empowerment as a potential mediator in the process. A survey research design was utilised in this study to gather data from 186 highly technical and knowledge-based members of different teams of South Korean firms. The results indicated that shared leadership is effective in a team context, positively affects members’ job crafting and knowledge sharing in a team context, and strongly promotes psychological empowerment. Furthermore, we found the intermediary effects of psychological empowerment. As one of the first to theoretically clarify, this study empirically tests and proves that shared leadership is a crucial antecedent for motivation and positive behaviours of team members. With the enlightening findings, the study offers valuable implications for leaders and managers to manage teams effectively.

This research explores the impact of authenticity and involvement on destination image, aiming to comprehend visitor satisfaction, experience quality, re-patronage intentions, willingness to pay more, and word-of-mouth. Structural equation modelling was employed for analysis using data from 394 visitors to Side, Turkey. According to research findings, authenticity and involvement positively influence destination image. The findings demonstrate that developing re-patronage intentions, word-of-mouth recommendations, and willingness to pay more can be facilitated through experience quality and satisfaction. Also, it is proved that satisfaction is positively influenced by destination image. Moreover, authenticity and involvement positively influence destination image. According to research results, to increase willingness to pay, it is imperative to offer a high-quality cultural tourism experience, wherein tourists gain knowledge about the heritage destination and enjoy the experience while deeply engaging with the surroundings. Furthermore, public and private organisations should design visitor experiences that consider authenticity and involvement to enhance destination image and increase customer satisfaction.

Servizi Elaborazioni Dati SpA is a public company owned by Municipality of L Aquila, it supplies the institution with network services and software applications for distributing services to citizens. The future policy of the company is to enlarge the offer of its services to nearby communities that are unable to set up and maintain their own network and software structures. This paper presents thus a possible architecture model to support small municipalities in supplying public services to citizens, with the aid of SED Spa. Through second level platforms based on Blockchain networks and Multi-agents Systems running on smart contracts, the system will focus on Waste Tax (Ta.Ri) management system in the Fascicolo del Cittadino environment.

Cloud computing has dramatically changed service deployment patterns. In this work, we analyze how attackers identify and target cloud services in contrast to traditional enterprise networks and network telescopes. Using a diverse set of cloud honeypots in 5~providers and 23~countries as well as 2~educational networks and 1~network telescope, we analyze how IP address assignment, geography, network, and service-port selection, influence what services are targeted in the cloud. We find that scanners that target cloud compute are selective: they avoid scanning networks without legitimate services and they discriminate between geographic regions. Further, attackers mine Internet-service search engines to find exploitable services and, in some cases, they avoid targeting IANA-assigned protocols, causing researchers to misclassify at least 15\% of traffic on select ports. Based on our results, we derive recommendations for researchers and operators.

AI services are known to have unstable behavior when subjected to changes in data, models or users. Such behaviors, whether triggered by omission or commission, lead to trust issues when AI works with humans. The current approach of assessing AI services in a black box setting, where the consumer does not have access to the AI's source code or training data, is limited. The consumer has to rely on the AI developer's documentation and trust that the system has been built as stated. Further, if the AI consumer reuses the service to build other services which they sell to their customers, the consumer is at the risk of the service providers (both data and model providers). Our approach, in this context, is inspired by the success of nutritional labeling in food industry to promote health and seeks to assess and rate AI services for trust from the perspective of an independent stakeholder. The ratings become a means to communicate the behavior of AI systems so that the consumer is informed about the risks and can make an informed decision. In this paper, we will first describe recent progress in developing rating methods for text-based machine translator AI services that have been found promising with user studies. Then, we will outline challenges and vision for a principled, multi-modal, causality-based rating methodologies and its implication for decision-support in real-world scenarios like health and food recommendation.

In recent days, the proliferation of several existing and new cyber-attacks pose an axiomatic threat to the stability of financial services. It is hard to predict the nature of attacks that can trigger a serious financial crisis. The unprecedented digital transformation to financial services has been accelerated during the COVID-19 pandemic and it is still ongoing. Attackers are taking advantage of this transformation and pose a new global threat to financial stability and integrity. Many large organizations are switching from centralized finance (CeFi) to decentralized finance (DeFi) because decentralized finance has many advantages. Blockchain can bring big and far-reaching effects on the trustworthiness, safety, accessibility, cost-effectiveness, and openness of the financial sector. The present paper gives an in-depth look at how blockchain and federated learning (FL) are used in financial services. It starts with an overview of recent developments in both use cases. This paper explores and discusses existing financial service vulnerabilities, potential threats, and consequent risks. So, we explain the problems that can be fixed in financial services and how blockchain and FL could help solve them. These problems include data protection, storage optimization, and making more money in financial services. We looked at many blockchain-enabled FL methods and came up with some possible solutions that could be used in financial services to solve several challenges like cost-effectiveness, automation, and security control. Finally, we point out some future directions at the end of this study.

Herein we examine the current state of gender (in)equity within Canadian interuniversity varsity sport (U SPORTS). In so doing, we build upon the previous work of Canada’s Centre for Sport Policy Studies at University of Toronto (see Norman et al., 2021). In our examination, we accessed all 56 U SPORTS universities’ Department of Athletics official webpages. We investigated the opportunities for women to participate as student-athletes on U SPORTS interuniversity varsity sport teams as well as opportunities for women to serve as sport leaders as their universities’ Directors of Athletics (DAs) and head coaches. Our findings suggest the current situation in Canadian universities remains bleak. We also argue that immediate attention and action is needed—by multiple potential stakeholders—for meaningful change to occur. Finally, considering these findings, we offer suggestions for moving forward and creating change.

Broadband Internet service is widely expected to be the fundamental universal service for the 21st century. But more than a decade of national and international struggles to close the digital divide between broadband haves and have nots suggest that reaching global universality will be a very difficult task. This paper argues that the strong guarantees made by the current broadband paradigm - low latency and constant availability - are unnecessary obstacles to its adoption as an affordable and universal digital service. We show that there is nonetheless a plausible strategy for deploying a Basic Broadband service that does not require such guarantees and is able to offer, at reasonable cost, almost all the critical and valuable services and applications currently delivered over low latency broadband, synchronous telepresence excepted.

Tourism is considered as one of the most relevant economic sectors at international level due to the multiple roles it holds, namely: economic, social role, cultural, educational and political. The COVID-19 pandemic caused significant damage globally and has expanded very quickly across the world by affecting almost all the industries due to the restrictions, lockdowns and quarantines. As a result of the pandemic crisis, the tourism sector was severely affected. Therefore, this paper aim is to reflect the negative and positive effects of the pandemic with SARS-COV-2 virus on tourism, and also to highlight the relevance and sensitivity of this sector during crisis events. The study focuses on the negative effects suffered by this sector during the pandemic, but also represents an effective opportunity to reconsider how that tourism interacts with our societies, thus, certain positive effects and strategies that were identified both on short and long- term, in order to try to minimize the shocks created by the pandemic. The economic crisis caused by the SARS-COV-2 virus has also encouraged inclining tourism towards upskilling, increasing the process of digitization of the ecosystem and protecting the environment.

El turismo ha sido el sector más afectado por la actual pandemia, lo que ha provocado la pérdida de puestos de trabajo y el cierre de pequeñas y medianas empresas (PYMES). Este trabajo de investigación tiene como objetivo determinar los factores que pueden ayudar a los restaurantes a ser más competitivos ante una crisis sanitaria. El estudio se realizó en la Ciudad de Zacatecas, Patrimonio Cultural de la Humanidad, y el pueblo mágico de Guadalupe, ubicados en el estado de Zacatecas de la República Mexicana. Con base en la revisión de la literatura, se construyó la variable latente «recursos» medida a través de cinco preguntas y «capacidades» a través de seis ítems. Para la prueba de hipótesis se realizó un análisis de ecuaciones estructurales de máxima verosimilitud. Los resultados muestran que las empresas que promueven alimentos con autenticidad y adhesión a las costumbres de la región pueden aumentar su competitividad.

We propose a Novel Fairness-Aware framework for Crowdsourcing Energy Services (FACES) to efficiently provision crowdsourced IoT energy services. Typically, efficient resource provisioning might incur an unfair resource sharing for some requests. FACES, however, maximizes the utilization of the available energy services by maximizing fairness across all requests. We conduct a set of preliminary experiments to assess the effectiveness of the proposed framework against traditional fairness-aware resource allocation algorithms. Results demonstrate that the IoT energy utilization of FACES is better than FCFS and similar to Max-min fair scheduling. Experiments also show that better fairness is achieved among the provisioned requests using FACES compared toFCFS and Max-min fair scheduling.

In this work, we show how to discover a semantic web service among a repository of web services. A new approach for web service discovery based on calculating the functions similarity. We define the Web service functions with Ontology Web Language (OWL). We wrote some rules for comparing two web services` parameters. Our algorithm compares the parameters of two web services` inputs/outputs by making a bipartite graph. We compute the similarity rate by using the Ford-Fulkerson algorithm. The higher the similarity, the less are the differences between their functions. At last, our algorithm chooses the service which has the highest similarity. As a consequence, our method is useful when we need to find a web service suitable to replace an existing one that has failed. Especially in autonomic systems, this situation is very common and important since we need to ensure the availability of the application which is based on the failed web service. We use Universal Description, Discovery and Integration (UDDI) compliant web service registry.

In addressing the universal deployment of digital services it is necessary to decide on the breadth of "universality" and the type of functionality of "digital services". These two decisions are linked: certain desirable functionality does not lend itself to being implemented in some environments or with certain constraints. In this paper we define universality as achieving a level of universality in digital service that can bridge the digital divide not only throughout highly industrialized societies but also across the globe and in the face of disruption. We then argue that some of the characteristics of current Internet broadband service, in particular support for synchronous telepresence such as videoconferencing, is a barrier to implementation strategies that could enable cheap and resilient universal deploymen

Purpose: of the study was to examine the validity of the Army Combat Fitness Test tests on a sample of air defense personnel in the Ukrainian Ground Forces. Material and methods. The respondents to this study were 271 air defense servicemen of the ground forces aged 18 to 40 years (73 cadets of the Ivan Kozhedub Kharkiv National Air Force University and 198 military personnel). The structural validity was evaluated using a confirmatory factor analysis. Results. Compliance was achieved with the two-factor model obtained in the course of exploratory factor analysis, as evidenced by the following indixes: χ2 (8, Critical N = 465.29) = 10.43; χ2 / df = 1.303; Non-Normed Fit Index = 0.98; Normed Fit Index  = 0.97; Root Mean Square Error of Approximation = 0.035 (90 Percent Confidence Interval for Root Mean Square Error of Approximation  = (0.0; 0.088), Comparative Fit Index = 0.99. In addition, all factor loadings were statistically significant at the p < 0.01 level, that indicates that these two factors were well designed at every stage. Correlation between factors was weak, which confirms the discriminant validity of the test. The significant correlation found between the items and the overall test score confirmed the validity of the test. Conclusions. It was found that Army Combat Fitness Test is a suitable tool for evaluating the physical fitness condition of air defense personnel into the Ground Forces. The dilemmas about the possible use of Army Combat Fitness Test for all age groups of military personnel regardless of gender require further study.

Grocery home delivery services require customers to be present when their deliveries arrive. Hence, the grocery retailer and the customer must mutually agree on a time window during which the delivery can be guaranteed. This concept is referred to as the Attended Home Delivery (AHD) problem. The phase during which customers place orders, usually through a web service, constitutes the computationally most challenging part of the logistical processes behind such services. The system must determine potential delivery time windows that can be offered to incoming customers and incrementally build the delivery schedule as new orders are placed. Typically, a Vehicle Routing Problem with Time Windows forms the underlying optimization problem. This work is concerned with the use case given by an international grocery retailer's online shopping service. We present an analysis of efficient solution methods that can be employed to AHD services. We provide several heuristic approaches for tackling the steps mentioned above. However, the basic framework can be easily be adapted to be used for many similar Vehicle Routing applications. We provide a comprehensive computational study comparing several algorithmic strategies, combining heuristics utilizing Local Search operations and Mixed-Integer Linear Programs, tackling the booking process. Finally, we analyze the scalability and suitability of the approaches.
