The past decades have witnessed a rise of culture-led urban regeneration. The successful cultural models have travelled throughout the world, and applied to cities and urban areas regardless of their size and location. Culture, ranging between high culture and contemporary creative economies, acquires potential to contribute to physical, social and economic aspects of urban regeneration. Successful examples of culture-led urban regeneration have tempted small cities to invest in traveling global cultural policies. Academic community has criticized these travelling policies for over-simplifying the abstract notion of culture, overrating the benefits of culture-led urban regeneration and ignoring local temporal specifics. This paper argues that a temporal analysis framework would enable a holistic approach to culture-led urban regeneration, and embrace the temporal uniqueness of urban contexts. This article discusses the temporal characteristics of culture-led regeneration in a provincial city context within an empirical case study analysis of Myllytulli in Oulu, Northern Finland. Myllytulli represents a district of regional cultural relevance where cultural amenities range from museums and educational facilities to creative bottom-up initiatives. This study reframes Myllytulli’s urban regeneration process using temporal conceptions of recent interdisciplinary academic discourse. The empirical data set consists of expert interviews, observation material and municipal planning documents. The results analyse the urban regeneration process within the linear temporal ideals of rational-comprehensive planning, reactive experiential urbanism and relational dimensions of time. The paper suggests time-sensitive approaches for future research and practice of urban regeneration.

Level Analysis

Purpose – The purpose of this paper is to examine, and present a comprehensive review of, the existing literature on the international manufacturing network (IMN). Design/methodology/approach – The original data set used for reviewing the IMN literature consisted of 107 articles selected from 21 journals: more specifically, 40 articles are concerned with plant-level analysis, and 67 articles are related to IMN-level analysis. The literature is simultaneously reviewed by two researchers. The relevance and contribution of each reviewed paper is discussed and mutually agreed upon. Findings – The paper highlights the different concepts related to IMN and traces the evolution of IMN-related research. Based on two levels of analysis (i.e. plant and network), this paper further reviews and discusses the IMN-specific literature in detail to determine the number of IMN articles published across the journals, the dominant methodologies employed, and the research focus reflected in IMN studies. A research trajectory is finally developed to provide an integrated and intuitional view on the development of IMN research. Originality/value – This is the first effort that has been made towards thoroughly investigating the existing literature on IMN, aiming to trace different concepts related to IMN from a historical perspective, to review and discuss the IMN-specific literature in detail, to provide an overview of the evolution trajectory of different existing IMN research themes, and to propose future research directions. Keeping in mind the growing importance of IMN for practitioners as well as the academic community, this study provides a timely overview of existing and emerging IMN research themes.

Regeneration Processes

Culture has become increasingly important in regeneration processes designed to deal with urban futures. Urban regeneration processes in which culture has played a prominent role range from large-scale public investments in cultural facilities and artefacts as ‘hallmarks’ of urban regeneration projects (e.g. Guggenheim Bilbao), through to the use of ‘one shot’ cultural events such as the Olympic Games as a catalyst and engine for regenerating urban areas. The aim of this paper is to examine the association between social capital (SC), local communities and the culture-led regeneration process at Sydney Olympic Park (SOP), New South Wales, Australia. The catalyst for the transformation of an industrial wasteland into SOP was the awarding of the Olympics to Sydney in 1993. A convenience sample of 47 professional reports associated with the regeneration process at SOP between 1993 and 2010 were analyzed, the aim being to understand how local communities had been linked to the regeneration process through SC. Results from the analysis identified three principal associations between SC, local communities and the ongoing SOP regeneration process. The first association related to how, during the early years of the regeneration process, SC was used as a means of expressing concern about how governance mechanisms implemented at SOP might adversely impact the ability of local communities to engage in decision making that affected their local environment. The second related to the use of community development programs to build SC in local communities through the SOP development. The third related to a call for the development of measures to understand how the development of SOP impacts on the SC in local communities. Eight in-depth interviews with professionals involved in the regeneration process were used to provide further insights into the three principal associations. The paper discusses findings through reference to broader arguments surrounding the potential, capacity and nature of SC.

PurposeIn recent years, Industry 4.0 has received immense attention from academic community, practitioners and the governments across nations resulting in explosive growth in the publication of articles, thereby making it imperative to reveal and discern the core research areas and research themes of Industry 4.0 extant literature. The purpose of this paper is to discuss research dynamics and to propose a taxonomy of Industry 4.0 research landscape along with future research directions.Design/methodology/approachA data-driven text mining approach, Latent Semantic Analysis (LSA), is used to review and extract knowledge from the large corpus of the 503 abstracts of academic papers published in various journals and conference proceedings. The adopted technique extracts several latent factors that characterise the emerging pattern of research. The cross-loading analysis of high-loaded papers is performed to identify the semantic link between research areas and themes.FindingsLSA results uncover 13 principal research areas and 100 research themes. The study discovers “smart factory” and “new business model” as dominant research areas. A taxonomy is developed which contains five topical areas of Industry 4.0 field.Research limitations/implicationsThe data set developed is based on systematic article refining process which includes the keywords search in selected electronic databases and articles limited to English language only. So, there is a possibility that other related work may not be captured in the data set which may be published in other than examined databases and are in non-English language.Originality/valueTo the best of the authors’ knowledge, this study is the first of its kind that has used the LSA technique to reveal research trends in Industry 4.0 domain. This review will be beneficial to scholars and practitioners to understand the diversity and to draw a roadmap of Industry 4.0 research. The taxonomy and outlined future research agenda could help the practitioners and academicians to position their research work.

Aims. Children’s online activities can result in serious consequences in their offline lives. Although Facebook is one of the biggest and most popular social networks in the world, there is little scientific research on cyberbullying via this social network because it is a new phenomenon. This study had the aim of examining children's behavior and experiences of violence on the Facebook social network. This seems to be the first research on cyberbullying on social networks in Croatia.Methods. Data presented in this paper were collected as part of an extensive research project conducted in 2013 by NGO Brave Phone and The Child Protection Center of Zagreb. The sample consisted of 1,489 children in Croatia aged 11 to 18 in rural and urban areas that completed the Scale of Victimization on Facebook and Scale of Committing Violence via Facebook.Results. Our results show that the average age when cyberbullying is most prevalent is between the ages of 15 and 16. In the overall sample, 12.1% of them experience abuse on Facebook, while 9.6% of them are abusive. The analysis of the children who were involved in  abuse on Facebook in any way, showed that 44.4% of them experienced abuse, 29.7% showed abusive behavior, while 25.9% of children both experienced abuse and were abusive on Facebook. Victims are mostly girls (60%), while boys commit cyberbullying more often (62%). Also,  58% of mixed cybervictims and cyberbullies are boys.Discussion. The results of prevalence of cyberbullying in our study are similar to those of previous population based studies. It is important to point out that although the prevalence of bullying was high; it is mostly a rare experience for the majority of children.Conclusions. Cyberbullying is a serious and growing problem and the academic community has to continue with the extensive research and development of practical prevention and intervention programs. Future research aimed at examining methods of coping with negative experiences on the Internet is necessary and there is a strong need for more research considering coping strategies of adolescents struggling with cyber victimization.

Abstract Purpose The aim of this study was to investigate the associations between quality of life and both perceived and objective availability of local green and blue spaces in people with dementia, including potential variation across rural/urban settings and those with/without opportunities to go outdoors. Methods This study was based on 1540 community-dwelling people with dementia in the Improving the experience of Dementia and Enhancing Active Life (IDEAL) programme. Quality of life was measured by the Quality of Life in Alzheimer’s Disease (QoL-AD) scale. A list of 12 types of green and blue spaces was used to measure perceived availability while objective availability was estimated using geographic information system data. Regression modelling was employed to investigate the associations of quality of life with perceived and objective availability of green and blue spaces, adjusting for individual factors and deprivation level. Interaction terms with rural/urban areas or opportunities to go outdoors were fitted to test whether the associations differed across these subgroups. Results Higher QoL-AD scores were associated with higher perceived availability of local green and blue spaces (0.82; 95% CI 0.06, 1.58) but not objective availability. The positive association between perceived availability and quality of life was stronger for urban (1.50; 95% CI 0.52, 2.48) than rural residents but did not differ between participants with and without opportunities to go outdoors. Conclusions Only perceived availability was related to quality of life in people with dementia. Future research may investigate how people with dementia utilise green and blue spaces and improve dementia-friendliness of these spaces.

This article presents logistic models examining how pandemic anxiety and COVID-19 comprehension vary with digital confidence among adults in the United States during the first wave of the pandemic. As we demonstrate statistically with a nationally representative data set, the digitally confident have lower probability of experiencing physical manifestations of pandemic anxiety and higher probability of adequately comprehending critical information on COVID-19. The effects of digital confidence on both pandemic anxiety and COVID-19 comprehension persist, even after a broad range of potentially confounding factors are taken into account, including sociodemographic factors such as age, gender, race/ethnicity, metropolitan status, and partner status. They also remain discernable after the introduction of general anxiety, as well as income and education. These results offer evidence that the digitally disadvantaged experience greater vulnerability to the secondary effects of the pandemic in the form of increased somatized stress and decreased COVID-19 comprehension. Going forward, future research and policy must make an effort to address digital confidence and digital inequality writ large as crucial factors mediating individuals’ responses to the pandemic and future crises.

In this paper, we present a novel interdisciplinary approach to study the relationship between diffusive surface structures and their acoustic performance. Using computational design, surface structures are iteratively generated and 3D printed at 1:10 model scale. They originate from different fabrication typologies and are designed to have acoustic diffusion and absorption effects. An automated robotic process measures the impulse responses of these surfaces by positioning a microphone and a speaker at multiple locations. The collected data serves two purposes: first, as an exploratory catalogue of different spatio-temporal-acoustic scenarios and second, as data set for predicting the acoustic response of digitally designed surface geometries using machine learning. In this paper, we present the automated data acquisition setup, the data processing and the computational generation of diffusive surface structures. We describe first results of comparative studies of measured surface panels and conclude with steps of future research.

Comprehensive Survey

Information-Centric Networking (ICN) has recently emerged as a prominent candidate for the Future Internet Architecture (FIA) that addresses existing issues with the host-centric communication model of the current TCP/IP-based Internet. Named Data Networking (NDN) is one of the most recent and active ICN architectures that provides a clean-slate approach for Internet communication. NDN provides intrinsic content security where security is directly provided to the content instead of communication channel. Among other security aspects, Access Control (AC) rules specify the privileges for the entities that can access the content. In TCP/IP-based AC systems, due to the client-server communication model, the servers control which client can access a particular content. In contrast, ICN-based networks use content names to drive communication and decouple the content from its original location. This phenomenon leads to the loss of control over the content, causing different challenges for the realization of efficient AC mechanisms. To date, considerable efforts have been made to develop various AC mechanisms in NDN. In this article, we provide a detailed and comprehensive survey of the AC mechanisms in NDN. We follow a holistic approach towards AC in NDN where we first summarize the ICN paradigm, describe the changes from channel-based security to content-based security, and highlight different cryptographic algorithms and security protocols in NDN. We then classify the existing AC mechanisms into two main categories: Encryption-based AC and Encryption-independent AC . Each category has different classes based on the working principle of AC (e.g., Attribute-based AC, Name-based AC, Identity-based AC). Finally, we present the lessons learned from the existing AC mechanisms and identify the challenges of NDN-based AC at large, highlighting future research directions for the community.

Large-scale adoption of drone-based delivery in urban areas promise societal benefits with respect to emissions and on-ground traffic congestion, as well as potential cost savings for drone-based logistic companies. However, for this to materialise, the ability of accommodating high volumes of drone traffic in an urban airspace is one of the biggest challenges. For unconstrained airspace, it has been shown that traffic alignment and segmentation can be used to mitigate conflict probability. The current study investigates the application of these principles to a highly constrained airspace. We propose two urban airspace concepts, applying road-based analogies of two-way and one-way streets by imposing horizontal structure. Both of the airspace concepts employ heading-altitude rules to vertically segment cruising traffic according to their travel direction. These airspace configurations also feature transition altitudes to accommodate turning flights that need to decrease the flight speed in order to make safe turns at intersections. While using fast-time simulation experiments, the performance of these airspace concepts is compared and evaluated for multiple traffic demand densities in terms of safety, stability, and efficiency. The results reveal that an effective way to structure drone traffic in a constrained urban area is to have vertically segmented altitude layers with respect to travel direction as well as horizontal constraints imposed to the flow of traffic. The study also makes recommendations for areas of future research, which are aimed at supporting dynamic traffic demand patterns.
