This paper aims to shed light on the impact of personalized news media on the shared issue agenda that provides democracies with a set of topics that structure the public debate. The advent of personalized news media that use smart algorithms to tailor the news offer to the user challenges the established way of setting the agenda of such a common core of issues.

This paper tests the effects of personalized news use on perceived importance of these issues in the common core. In particular, the authors study whether personalized news use leads to a concentration at the top of the issue agenda or to a more diverse issue agenda with a long tail of topics.

Based on a cross-sectional survey of a representative population sample (n = 1,556), we find that personalized news use does not lead to a small common core in which few topics are discussed extensively, yet there is a relationship between personalized news use and a preference for less discussed topics. This is a result of a specific user profile of personalized news users: younger, more educated news users are more interested in topics at the fringes of the common core and also make more use of personalized news offers.

The results are discussed in the light of media diversity and recent advances in public sphere research.

This paper contributes to the ongoing debate about algorithmic news dissemination. While, currently, much attention is reserved for the role of platforms as information gatekeepers in relationship to the news media, maybe their ability to enable or hinder the audience in discovering and distributing news content is part of what really characterizes their influence on the market place of ideas.

Science policy and practice for open access (OA) books is a rapidly evolving area in the scholarly domain. However, there is much that remains unknown, including how many OA books there are and to what degree they are included in preservation coverage. The purpose of this study is to contribute towards filling this knowledge gap in order to advance both research and practice in the domain of OA books.

This study utilized open bibliometric data sources to aggregate a harmonized dataset of metadata records for OA books (data sources: the Directory of Open Access Books, OpenAIRE, OpenAlex, Scielo Books, The Lens, and WorldCat). This dataset was then cross-matched based on unique identifiers and book titles to openly available content listings of trusted preservation services (data sources: Cariniana Network, CLOCKSS, Global LOCKSS Network, and Portico). The web domains of the OA books were determined by querying the web addresses or digital object identifiers provided in the metadata of the bibliometric database entries.

In total, 396,995 unique records were identified from the OA book bibliometric sources, of which 19% were found to be included in at least one of the preservation services. The results suggest reason for concern for the long tail of OA books distributed at thousands of different web domains as these include volatile cloud storage or sometimes no longer contained the files at all.

Data quality issues, varying definitions of OA across services and inconsistent implementation of unique identifiers were discovered as key challenges. The study includes recommendations for publishers, libraries, data providers and preservation services for improving monitoring and practices for OA book preservation.

This study provides methodological and empirical findings for advancing the practices of OA book publishing, preservation and research.

This study aims to estimate the firm size distributions that belong to the service sector and manufacturing sector in Korea.

When estimating the firm size distribution, the author considers the following two major factors. First, the firm size distribution can have a gamma distribution rather than traditional accepted distributions such as Pareto distribution or log-normal distribution. In particular, industry-specific enterprises can have different size distributions of the type of gamma distribution. Second, the firm size distribution that is applied to this study’s data set should reflect a number of factors. For example, estimating mixture gamma distribution for firm size distribution should be required and compared, because the total amount of configuration data is composed of small businesses, medium-sized and large companies.

Using 8,230 number of firm data in 2013, the author estimates mixture gamma distribution for the firm size.

From the comparison, empirical results are found for the following characteristics of core firm size distribution: first, the firm size distribution of the manufacturing sector has a longer tail than firm size distribution of the service sector. Second, the manufacturing firm size distribution dominates the entire country firm size distribution. Third, one factor among the three factors that make up the mixed gamma firm size distribution is described for 99 per cent of the firm size distributions. From the estimated firm size distributions of the service sector and manufacturing sector in Korea, the author simply implies the strategy and policy implications for the start-up firm.

The purpose of this paper is to widen the understanding of the shifts the tourism industry experienced as it went though the Covid-19 pandemic. To contribute to this question, an empirical comparison is made between the supply of guided tours and sights at an urban destination in the pre- and postpandemic eras, thus gauging the changes in the guiding tours industry after the pandemic.

By conducting a convenience data gathering and a double-level analysis (tours analysis and sights analysis) on the tours and attractions supply at an urban destination, underlying trends come to light, related to the changes in the postpandemic era. This empirical comparison (2019 vs 2022) allows the authors to assess what has and has not changed in the postpandemic context.

Guided tours and attractions supply are evolving in the researched destination, but at a slow pace. Therefore, we conclude that long-term processes in destinations prevail over short-term disruptions, no matter how strong these disturbances are.

The results are of interest to practitioners as they facilitate a better assessment of the impacts of a crisis and greater awareness of the evolution of attractions in urban tourism. While the “staple tours” in a destination are always there, practitioners should keep an eye on new spaces in the city which the sector is opening up and also new touring trends.

This study is one of the few to empirically compare a pre- and postpandemic situation, as far as city-guided tours are concerned. It helps practitioners and authorities in urban destinations to assess the new trends that have emerged in the postpandemic era, and offers a two-level tool for tour analysis that could be applied to any urban destination.

The main argument behind this paper is learning in the digital age should not be restricted to creating digital infrastructures for supporting current forms of learning nor taking schools in their current form as God-given, natural entities, but changing current forms of education by developing new frameworks and socio-technical environments for making learning an integral part of life. The authors provide a framework for this argumentation as well as a call-to-action for research on the co-evolution of learning, media, and learning organizations.

This paper theoretically and argumentatively explores the core assumption that the digitalization of society results in challenges and opportunities for learning and education based on fundamental transformations (Collins and Halverson, 2009; Fischer et al., 2020).

The digital age greatly enhances the opportunities and supports the necessity for “making learning a part of life”. But while the growth of technology is certain, the inevitability of any particular future is not. The impact of schooling goes beyond that new information about computers, the Internet, and social media are integrated into the schools of today. The transformation of schools needs to be informed by an understanding of the impact of mindset formation that will determine people's approach to learning for the rest of their lives. The authors’ framework is focused on moving “beyond gift-wrapping” by not only fixing and existing systems but to change them and not only reforming but transforming them.

It is the authors’ hope that this article will be of interest to many stakeholders (including learners, teachers, curriculum designers, technology experts, parents, and politicians) and provide a foundation for an ongoing debate and informed actions for “Making Learning a Part of Life” in the digital age.

Birds are biological indicators for environment health in which their sightings and abundance could reflect a certain situation or become evaluation tool for co-existence of another species. Here, the study aims to observe urban settlements with substantial forestation, may it be artificial or natural, and the occurrence of bird assemblage across time. Considering the foraging activity of birds hardcoded with sustainability, their spatial overlap resultant into service provision, which can mean, baseline occurrence or an expected encounter equates to support system for ecological vigour.

From this, birds could indicate external environment vulnerability related to climatic fluctuations, whereby documentation of their arrival across spatial-temporal regimes allowed us to understand their distribution between residential and forested areas.

Though urban birds are abundant and viewed less important for conservation, the existence of certain species such as long-tailed shrike and little green pigeon disclose the types of food they consume and, the other types of birds attracted to their prey. With regard, the sightings of these birds would mean an encounter with 20 or more other species at a bird watching occasion, though it is limited to the sightings of urban birds.

Subject to criteria for green space, attaining plenty of bird species provides understanding of food availability, the support services and opportunity for urban birds to thrive in midst the opportunity for resources such as food, perching grounds and sufficient numbers of counterparts to reproduce into healthy urban bird populations.
