Abstract
This study investigates why contributors to online volunteer organizations reduce activity or discontinue volunteering. First, this analysis, based on a survey of over a 100 English Wikipedia’s volunteers with the highest edit count, identifies a gap in the research on volunteers burnout/dropout, namely the importance of interpersonal conflict as an understudied yet highly significant factor. Second, this analysis has practical implications for the sustainability of the Wikipedia project. Third, this analysis should outline an underrepresented issue that if generalizable, may help other volunteer organizations identify a key area related to their volunteer burnout/dropout.

Abstract
Purpose
Develop a comprehensive framework for assessing the knowledge organization systems (KOSs), including the taxonomy of Wikipedia and the ontologies of Wikidata, with a specific focus on enhancing management and retrieval with a gender nonbinary perspective.
Design/methodology/approach
This study employs heuristic and inspection methods to assess Wikipedia’s KOS, ensuring compliance with international standards. It evaluates the efficiency of retrieving non-masculine gender-related articles using the Catalan Wikipedian category scheme, identifying limitations. Additionally, a novel assessment of Wikidata ontologies examines their structure and coverage of gender-related properties, comparing them to Wikipedia’s taxonomy for advantages and enhancements.
Findings
This study evaluates Wikipedia’s taxonomy and Wikidata’s ontologies, establishing evaluation criteria for gender-based categorization and exploring their structural effectiveness. The evaluation process suggests that Wikidata ontologies may offer a viable solution to address Wikipedia’s categorization challenges.
Originality/value
The assessment of Wikipedia categories (taxonomy) based on KOS standards leads to the conclusion that there is ample room for improvement, not only in matters concerning gender identity but also in the overall KOS to enhance search and retrieval for users. These findings bear relevance for the design of tools to support information retrieval on knowledge-rich websites, as they assist users in exploring topics and concepts.

Abstract
Purpose
The purpose of this paper is to study the overall framework in which the Urban Air Mobility (UAM) deployment is expected to be implemented. Another aim of the study is to give a better overview on the current regulations and standards including the impact of the regulations on the industry, operations and cities.
Design/methodology/approach
This paper performs a literature review on the regulatory framework, which provides a clear view of the current regulations and standards. The review includes the insight into the details of possible international rules for the future, considering operations in the specific and certified categories. The impact and trends of current and future regulations are also presented.
Findings
The analysis described in this paper shows a strong upward trend in UAM technical and operational developments as well as further potential for a successful incorporation in city mobility concepts. This paper indicates the importance of the representatives of guideline development organizations, industry, agencies and other important players involved in the standard development process.
Practical implications
This section describes synthesis on the required level of safety for UAM operations as well as description on the impact of the regulations from different perspectives, including industry and certification of urban aircraft, operations and air traffic management, cities and the governance of the urban airspace and well as technology.
Originality/value
Barriers such as legislation do not allow the common UAM to be deployed. This paper studies the overall framework in which the UAM deployment is expected to be implemented.

Abstract
Purpose
Process of building and then implementation of integrated multimodal, passenger-centred and predominantly sustainable transport system will require a specific effort to be input in preparation, especially if it covers new entrants like passenger Urban Air Mobility. This paper aims to address the first step which is the identification of barriers to be overcome to turn the concept into reality.
Design/methodology/approach
Comparison of the current state-of-the-art in transportation, Information and Communication Technologies as well as other city planning domains to the forecasted ecosystem, described in the form of scenarios where base for definition of necessary actions, challenges as well as potential barriers and obstacles were identified and thoroughly specified.
Findings
Barriers grouped in five categories: policy, digitalisation, transportation technologies, integration technologies and passengers’ needs allow for formulation of the relevant roadmaps defining optimal development path towards fully integrated multimodal, passenger-centred and sustainable transport system.
Research limitations/implications
Conclusions can be a starting point in studies towards development of roadmap for implementation of truly integrated municipal transport system both sharing the resources as well as high-level objectives.
Practical implications
Conclusions can be exploited in various areas starting from preparation of strategies in cities aspirating to be smart, through definition of technology development priorities by relevant agencies ending with industry actors looking for better trimming their business.
Originality/value
The identified barriers as derived from detailed investigation enable deep insight into the total transport system vision in which Urban Air Mobility integrated within urban mobility ecosystem is considered as game-changing factor having large potential to contribute to both making cities smart and sustainable.
