The production of food within cities through urban agriculture can be considered as a nature-based solution and is argued to be an important response to the current COVID-19 pandemic as well as to climate change and other urban challenges. However, current research on urban agriculture is still fragmented, calling for a systematic and integrative assessment of different forms of urban agriculture and the drivers and constraints for their effective realization. In this context, the Special Issue presents conceptual and empirical research articles from around the world on the impact and implementation potential of various types of urban agriculture. The studies of this Special Issue cover a broad range of impact and implementation dimensions, asssessment methods and geographical backgrounds that can support future studies to develop a systemic perspective on urban food production.

In recent years, short-term rental platforms in the lodging sector, including Airbnb, VRBO, and HomeAway, have received extensive attention and emerged as potentially alternative suppliers of services traditionally provided by established commercial accommodation providers, that is, hotels. Short-term rentals have dramatically increased the available supply of rooms for visitors to multiple international destinations, potentially siphoning demand away from hotels to short-term rental businesses. In a competitive market, an increase in supply with constant demand would negatively influence incumbent service providers. In this article, we examine the substitution effects of short-term rental supply on hotel performance in different cities around the world. Specifically, we comprehensively investigate the substitution effects of short-term rental supply on hotel performance based on hotel class, location type, and region. Furthermore, we segment the short-term rental supply based on its types of accommodations, that is, shared rooms, private rooms, and entire homes, and both examine and quantify the differential effects of these types of short-term rentals on different types of hotels. This study offers a comprehensive analysis regarding the impact of multiple short-term rental platforms on hotel performance and offers both conceptual and practical insights regarding the nature and extent of the effects that were identified.

Urban agriculture has become a favored activity in many cities around the world. This study explores how urban agriculture’s potential can be maximized in Seoul, South Korea, a city characterized by high-density residential complexes. It selects six existing residential complexes with representative site typologies and diverse density levels. The study’s aim is to assess the impact of various typology and density settings on percentages of ground-level surface with direct sunlight above certain thresholds during warmer seasons when crops can grow. DIVA-for-Rhino is used for simulation. The findings suggest that parallel typologies and lower density levels offer the best performance, while other combinations show mixed results. This study could benefit citizens and policymakers to facilitate urban agriculture practices around the world by suggesting feasible solutions for high-density residential developments.

The interventions presented in the current special issue have the potential to decrease social and economic gaps. At the same time, several important aspects that are central to the rapid changes in education and in the world of work were not included or given minimal attention in these interventions. In this concluding article, we reflect upon these issues in the hope that future studies and career education work will focus and elaborate upon theme.

This Special Issue, “Embryo-Maternal Interactions Underlying Reproduction in Mammals”, gathers a collection of 23 articles, 16 original research articles and 7 up-to-date reviews, providing new findings or summarizing current knowledge on embryo–maternal interactions in seven different mammalian species including humans. Considering the different players involved in these embryo-maternal interactions, articles are mainly focused on one of these different players: the oviduct, the uterus, the embryo or the emergent extracellular vesicles. Additionally, a few articles bring up the impact of reproductive, but also non-reproductive, diseases, as well as stress factors, on the establishment of pregnancy. We hope the readers enjoy this collection of articles and that the knowledge assembled here will support and inspire current and future research investigations. We would like to thank all authors for their contributions to this Special Issue.

Countries have become increasingly concerned about the safety of their food. Many countries have imposed standards on both domestically produced and imported food. In particular, countries have implemented regulations to control the quantity and quality of vegetable imports. Maximum Residue Limit (MRL) standards are one of the main restrictions adopted by numerous countries. Japan has one of the strictest MRL standards in the world. This study builds on previous studies to explore the impact of MRL standards on Japanese vegetable imports. Gravity models are used to analyze how MRL standards influence the Japanese imports of different types of vegetables (fruit vegetables, leafy vegetables, bulb vegetable, and root vegetables). The results reveal that the trade impacts of MRL standards are different for different types of vegetables, with the most significant impact on imports of leafy and fruit vegetables and the least significant impact on imports of bulb vegetables.

What is the meaning of the word "applied" in our pages? It seems to us that most of our articles fall in one of the following four categories: 1) The description and analysis of some social situation in largely theoretical terms. The case may be from the United States or from some other part of the world. It may deal with a group or a community or an organization. If it is a good study, it at least has implications for action. And, if it is a good study, we will be happy to publish it, but we will be even happier to publish a good theoretical statement that fits into one of the categories below. 2) The failure story. Here the researcher describes how a practitioner handled a problem and got it badly bungled up because he failed to act in terms of the principles of applied anthropology which the author points out. We will continue to print good articles along this line, yet with diminishing enthusiasm. When the mistakes have been committed, it is all too easy to recognize them, but let's not make life too easy for ourselves. (Maybe someday a practitioner will write an article for us on "Blunders I Have Seen Researchers Make.") 3) The success story. Here the author reports how the practitioner handled a human problem successfully—and analyzes the factors underlying this success. Excellent examples of this type can be found in F. L. W. Richardson's special issue on "Five Case Studies of Successful Experiments In Increasing Food Production" published in far-off 1943.

Abstract This introduction to the Special Issue on Networked Emotion and Stancetaking summarizes the individual and collective contribution of the included five research articles. We argue for the relevance of discourse-pragmatic theories, methods, and concepts for furnishing cross-disciplinary perspectives into the study of emotion online. Such perspectives are arguably needed in order to clarify the intricate connections between (re)presentations of emotion online and changing practices of news-making and news consumption, story sharing and participation, and public stancetaking in social media and beyond. We propose that empirical analyses of networked practices of stancetaking – epistemic, affective, or narrative – can pinpoint the construction and dissemination of different types of participant positions and stances, including multimodal ones, as well as the creation and uptake of specific frames for interpreting events and crises affectively.

Purpose The purpose of this paper is twofold: first, to assess the impact of the 1999 Special Issue on Professionalization in Asia in the Accounting, Auditing and Accountability Journal (AAAJ); and second, more generally to review research on this topic post-1999. Design/methodology/approach The paper starts with a discussion of the research articles of the Special Issue. It then identifies research that has cited papers in the Special Issue and which focusses on professionalization in Asia to identify relevant subsequent research. In addition, a literature search is conducted to locate post-1999 work that has not cited papers from the Special Issue but has investigated the same topic area. Analyzing both sets of work enables an integrated review of the field and aids the identification of future research opportunities. The study covers published research articles and books on professionalization projects in Asia from 1999 to 2018. In this paper, reference to Asia focusses on East Asia (including countries such as China and Japan), South Asia (including countries such as Bangladesh, India and Sri Lanka), and South East Asia (including countries such as Brunei, Cambodia, Indonesia, Malaysia, the Philippines and Vietnam). Given the elapsed time of near 20 years, there has been sufficient time for research to be published. Therefore, the review focusses on published output only and does not discuss unpublished theses, conference proceedings nor working papers. Findings First, the Special Issue of AAAJ in 1999 generally adopted a critical lens and studied professionalization as projects of market closure and collective mobility. The corporatist framework of Puxty et al. (1987) provided a useful framing to analyze the influence of states, markets and communities on professionalization. Second, the Special Issue has helped to spur interest in understanding professionalization in the region. Post-1999, there are studies of countries not covered in the Special Issue. Third, the themes identified in the Special Issue continue to be relevant and are examined in post-1999 work: the active role of the state, the legacies of colonization, the activities of transnational accounting bodies; and to a lesser degree, the influence of transnational accounting firms. Finally, future research could usefully focus on: the distinctive and more expansive role of Asian state agencies; the conduct of deeper comparative research; the role of accounting firms in the region; and the impact of transnational agencies such as the International Federation of Accountants and the World Bank. Research limitations/implications There are three limitations. First, the review of literature omits unpublished research such as PhD theses and working papers. Second, it focusses only on research published in English. As a result, some work may be excluded. Third, it assesses the contribution of a single issue (i.e. the 1999 AAAJ Special Issue) and does not discuss work that preceded 1999. Originality/value This paper is aimed at assessing the impact of the 1999 Special Issue but also presents a wide-ranging analytical review of published research on accounting professionalization in Asia since 1999. The paper identifies several areas for future research and proposes a modified model of state-market-community-profession relations. In particular, the paper emphasizes the large and distinctive roles of Asian state agencies and the activities of transnational actors (both those within the profession as well as those that are external).

Many societies in the world live with different types of risks and the threat of disasters has always presented a major challenge to devise ways to achieve sustainable development by reducing patterns of vulnerability. Disaster reduction is therefore crucial and must have a place in national policies in order to create favourable conditions for effective and efficient hazard mitigation at various levels. This can help in increasing the resilience among communities at risk by enabling them to withstand shocks, cope with emergencies as they bounce back from the impact and adapt in new ways to cope with future threats. The aim of this paper is to explore the concept of resilience in general and what this means before, during, and after disaster impact. Case studies are cited to indicate how resilience operates or fails to occur and why. The study defines how resilience can be developed to create sustainable systems and structures that focus on robustness, redundancy, resourcefulness and rapidity.
