In recent years, the question of “difference” has become a central feature of public debate and social concern, especially in the context of transnational migration. The underlying question that we attempt to answer in this article is: how can we talk about difference without reinforcing prejudice? Starting from the observation that perceptions and representations of difference have an impact on the way that individuals and groups interact with each other in increasingly diverse urban environments, we argue that a systemic approach to the analysis of intercultural situations gives us a unique window into emerging discourses and evolving norms about difference. After a brief historical overview of debates surrounding cross-cultural comparison in anthropology, we consider how various fields outside of anthropology have drawn inspiration from anthropology in order to gain a deeper understanding of intercultural dynamics in various professional settings. This article also examines several anthropological concepts that have been used as tools to theorize cross-cultural comparison, and how participants in a new research methodology use the systemic notion of “cultural variables” to resolve the basic paradox underlying pluralist philosophy and practice.

Against the background of urban redevelopment programs through the lens of varied, country-related planning cultures, this article sets the stage for learning from one country’s recent experience. In this article, we focus on two Israeli urban regeneration programs operating since 2000: the ‘Integrated National Planning Scheme’ (TAMA 38) and ‘Evacuate and Build’ (Pinuy Binuy) programs. This article aims to examine the governmental agenda behind these programs in comparison to previous urban regeneration programs and, especially, to critically review the implementation and implication of these programs considering social sustainability issues. Methodologically, the policies and practices of this recent wave of urban renewals in Israel are revisited through a critical reading of a series of studies from the last five years, bringing together multidimensional societal aspects. In terms of ethics and qualitative dimensions, the examined societal aspects are rooted in social sustainability theory and contemporary urban policy design. Our findings regarding this country-related recent experience in urban renewals have identified several gaps concerning certain aspects of social sustainability theory and practice. These gaps call for a better understanding by Israel’s urban policy makers of the comprehensive essence of contemporary social sustainability theory, which should also be mirrored in the respective professional discourse. The gaps are also useful in informing our accumulating transnational knowledge and experience in urban renewal schemes, based on a chain of country-related experiences and planning cultures.

Current research has revealed that global trade promotes transnational investment and contributes to large amounts of CO2 emissions. Recently, trade protectionism has gradually emerged. This study aims to explore the effect of global trade protection on investment-related CO2 emissions. We construct an accounting framework for investment-related CO2 emissions under trade freedom and trade restriction based on the MRIO model for the first time, and investment-related CO2 emissions in 16 economies are determined in both trade freedom and trade restriction scenarios. The study uses normal trade and no-trade scenarios instead of free trade and restricted trade scenarios. Then, based on the comparison of the two scenarios, the effect of global trade protection on investment-related CO2 emissions is revealed from the three levels of country, section, and trade links. It is found that global trade protection would lead to an increase of up to 546.17 million tons in investment-related CO2 emissions under current trade structures. Transnational investment in the trade of end-stage intermediary goods contributed 81.6% of the total effect. In terms of countries, trade protection is quite disadvantageous to CO2 emission reduction in China and India, and their CO2 emissions would respectively increase by 105 million tons and 141.5 million tons compared to normal trade. The electricity, gas, and water supply sectors and the manufacturing sector are the main sectors for investment-related CO2 emissions. This study reveals the effect of trade freedom and trade protection on the environment of various countries from the viewpoint of investment-related CO2 emissions, which has important reference value for global CO2 emission reduction in the context of the evolving trade situation.

Wetlands are complex ecosystems, considered among the most productive environments in the world. They contain important biodiversity hotspots, provide the resources on which countless plant and animal species depend and perform important environmental and economic functions. Wetlands reduce flooding events, improve water quality and represent a valuable cultural and natural heritage. The European Directive (2000/60/EC) requires fostering an integrated approach to wetland management through collaborative governance processes. The Wetland Contract is a tool that has been developed and implemented in order to promote the sustainable governance of water systems. Among the Mediterranean countries, Italy and Croatia count on a rich variety of coastal wetlands that, together with the plants and animals that inhabit and pass through them, constitute an extremely valuable natural heritage. This paper presents and discusses the results of the Interreg Project CREW that, between 2018–2021, contributed to the drafting of seven new Wetland Contracts. Through a comparative reading, the aim is to understand, on the one hand, how the different Contracts have responded individually to a shared programme based on European requirements; on the other hand, the aim is also to bring similar experiences closer together to assess their overall potential on an international scale. The article shows how the constant exchange between CREW partners and the continuous updating on ongoing activities, methodologies and proposed solutions in the seven target areas facilitated the construction of a shared cross-border strategy for wetland governance. The comparison also highlights some principles considered fundamental by all partners (protection and enhancement; integrated governance; awareness-raising and learning) that have served the construction of a transnational Observatory, aimed at monitoring, sharing practices and able to guide the formation of future Wetland Contracts.

Although conservation and development are two facets of sustainability, they are often placed in contradictory positions. In this context, planning systems are able to respond to investment pressure, especially in countries with underdeveloped institutional solutions for this purpose, and are consequently characterized by a shifting relationship between spatial planning and environmental protection. Although these issues have been relatively well conceptualized, the literature still lacks more in-depth analyses of selected case studies. In order to fill the gap, this study aimed to identify potential ways to protect the environment and natural values in urban areas from investment pressures in countries with less developed planning systems, based on a comparative Polish-Romanian perspective. The method consisted of comparing the national legal frameworks for environmental protection and spatial development and analyzing in detail two case studies from each country. The findings indicate that national protection is required in both countries to ensure the effective protection of natural areas situated within city administrative limits that provide important ecosystem services. Moreover, the results reveal the need for more research on similar areas using multi-scale interdisciplinary approaches and reviewing planning theory with respect to its efficiency in protecting nature.

The fast fashion industry is subject to growing calls for transparency, from civil society groups as well as consumers. Despite universal pressure on retailers to disclose information on supply chain practices, uptake of transparency policies and practices has been heterogenous amongst large fast fashion companies. In this paper, we explain variation in transparency practices through a comparison of the four largest fast fashion retailers: H&M, Inditex, Gap, and Fast Retailing. Drawing on cross-case comparison and within-case process tracing, we offer insights into why some retailers are more transparent than others. Our findings suggest that sustainability scandals are a necessary but insufficient condition for motivating firms to increase transparency in their supply chains. Scandals can be an important driver of increased transparency, but only when accompanied by support from senior management and alignment with domestic norms about appropriate corporate conduct. These findings contribute to the literature on transnational business governance, corporate transparency, and sustainable supply-chain management. Full article

Changes of the antenna models on permanent global navigation satellite system (GNSS) stations can lead to jumps and discontinuities in the coordinate time series. In this paper, the results of research on the adequacy of the antenna phase centre corrections (PCC) variations are presented by analysing its component—the antennas’ phase centre offset (PCO). For this purpose, height differences were determined using different and independent methods: EUREF Permanent Network (EPN) combined solutions, Precise Point Positioning (PPP), and the single baseline solution. The results of GNSS processing were referenced to direct geometric levelling outputs. The research was conducted only within the global positioning system (GPS) system due to the compatibility of one of the receivers, and the experiment was based on a comparison of the height differences between four GNSS antennas located on the roof of a building: two permanent station antennas and two auxiliary points. The antennas were located at similar heights; precise height differences were determined by geometric levelling, both at the beginning and the end of the session. Post-processing was conducted with the use of the GPS system, precise ephemeris, the adopted antenna correction model, and a zero-elevation mask. For one of the antennas, a change of the antenna characteristic model from IGS08 to IGS14 leads to an 8-mm difference in height. Older antennas used in the national (or transnational) permanent network need individual PCC. Full article

The capital requirements derived from the Basel Accord were issued with the purpose of deploying a transnational regulatory framework. Further regulatory developments on risk measurement is included across several documents published both by the European Banking Authority and the European Central Bank. Among others, the referred additional documentation focused on the models’ estimation and calibration for credit risk measurement purposes, especially the Advanced Internal-Ratings Based models, which may be estimated both for non-defaulted and defaulted assets. A concrete proposal of the referred defaulted exposures models, namely the Expected Loss Best Estimate (ELBE) and the Loss Given Default (LGD) in-default, is presented. The proposed methodology is eventually calibrated on the basis of data from the mortgage’s portfolios of the six largest financial institutions in Spain. The outcome allows for a comparison of the risk profile particularities attached to each of the referred portfolios. Eventually, the economic sense of the results is analyzed. Full article

Transnational trade holds opportunities for prosperity and development if accompanied by a robust political and legal framework. Yet, where such a framework is missing, transnational trade is frequently associated with, among others, negative impacts on the environment. Applying a legal comparison, this article assesses if recent free trade agreements, i.e., the Mercosur Agreement, CETA and the EU–Vietnam Free Trade Agreement, negotiated by the European Union, have been underpinned with effective environmental standards so that they are in line with global environmental goals and avoid detrimental effects on climate and biodiversity. Besides that, we evaluate the extent to which these agreements at least enable and incentivise environmental pioneering policies in the trading Parties. In particular, we discuss the likely impacts of the agreements on the agricultural sector. The analysis finds that, while a few mandatory standards concerning, e.g., deforestation have been established, overall, the agreements lack a comprehensive legal framework to uphold/enhance environmental protection. Moreover, weak dispute settlement mechanisms to ensure compliance with sustainability measures limits their effectiveness. In addition, the provisions on regulatory cooperation and investor-state dispute settlement are likely to negatively affect the decision-making processes and (thus) discourage ecological pioneering policies in the trading Parties. Hence, there is a long way to go so that transnational trade is compatible with global environmental goals. Full article

This article examines the beginning of transnational adoption in Denmark and Norway to illuminate the role of private actors and associations in Scandinavian welfare systems. Utilizing case studies of two prominent private adoption actors, Tytte Botfeldt and Torbjørn Jelstad, the article analyzes how these Nordic welfare states responded to the emergence of transnational adoption in comparison with both each other, neighboring Sweden, and the United States. This study shows that private actors and associations strongly influenced the nascent international adoption systems in these countries, by effectively promoting transnational adoption as a progressive and humanitarian form of global parenthood; while simultaneously emphasizing the responsibility of the welfare state to accommodate and alleviate childless couples’ human rights and need for children. A need that was strong enough that couples were willing to transcend legal, national, and racial borders. Ultimately, Danish and Norwegian authorities not only had to show leniency towards flagrant violations of adoption and child placement rules, but also change these so that families could fulfill their great need for children by legally adopting them from abroad.

In 2015, the UN adopted the Sustainable Development Goals (SDGs), addressing social, environmental, and economic targets. Global partnerships, transnational, and interdisciplinary research are essential for achieving progress towards the SDGs. This study analyzes 4593 research articles at the meta-level, explicitly referring to the SDGs. This a comparably small amount of research items directly addressing the goals. However, comparisons with existing approaches using different queries are possible. Research that links to the SDGs through its title, keywords, or abstract facilitates knowledge sharing on the goals as it is easier to identify relevant work. Using scientometric means, we assessed the corresponding sources, research areas, affiliated countries, thematic foci, and the availability of funding acknowledgments. The results are useful for identifying research gaps and potential collaboration possibilities. The outcomes suggest that most research referring to the SDGs comes from the research areas Life Sciences & Biomedicine and Social Sciences. The most predominant SDG among the analyzed research articles is SDG 3 (“good health and well-being”). A relatively high share of open access articles contributes to the idea of knowledge sharing for the SDGs. Nearly 37% of all articles count as international publications, i.e., as being co-authored by authors from affiliations of multiple countries. Full article

The Basque conflict was one of the last ethnonationalist violent struggles in Western Europe, until the self-dissolution in 2018 of ETA (Euskadi ta Askatasuna, Basque Country and Freedom). The role played by some sectors of the Roman Catholic Church in the mediation efforts leading to this positive outcome has long been underestimated, as has the internal pluralism of the Church in this regard. This article specifically examines the transnational dimension of this mediation, including its symbolic aspect. The call to involve the Catholic institution transnationally was not limited to the tangible outcomes of mediation. The mere fact of involving transnational religious and non-religious actors represented a symbolic gain for the parties in the conflict struggling to impose their definitions of peace. Transnational mediation conveyed in itself explicit or implicit comparisons with other ethnonationalist conflicts, a comparison that constituted political resources for or, conversely, unacceptable constraints upon the actors involved.

This article addresses the search for religion’s “suitable place” within International Relations (IR), taking as a starting point the social changes in the world (“reflexive modernity”) and the postulated “Mesopotamian turn” in IR. The assumption is that religion is present at each level of IR analysis in the Middle East and, thanks to that, more and more at the international system level. This presence of religion serves to undermine one of the basic assumptions lying at the heart of the modern international order (and therefore also IR), i.e., the so-called “Westphalian presumption”. The author, inter alia, emphasizes how more attention needs to be paid to the “transnational region” constituted by the Middle East—in association with the whole Islamic World. A second postulate entails the need for a restoration of the lost level of analysis in IR, i.e., the level of the human being, for whom religion is—and in the nearest future, will remain—an important dimension of life, in the Middle East in particular. It can also be noted how, within analysis of IR, what corresponds closely to the level referred to is the concept of human security developed via the UN system. The Middle East obliges the researcher to extend considerations to the spiritual dimension of security, as is starting to be realized (inter alia, in the Arab Human Development Reports). It can thus be suggested that, through comparison and contrast with life in societies of the Middle East as it is in practice, religion has been incorporated quite naturally into IR, with this leaving the “Westphalian presumption” undermined at the same time. The consequences of that for the whole discipline may be considerable, but much will depend on researchers themselves, who may or may not take up the challenge posed. Full article

It is challenging to quantify the production of wood-based biomass, to define the type and where it comes from, how it is used, and the amount that remains available. This information is crucial for the implementation of national and transnational regulations and is a pillar for the development of the future bio-based circular economy. A variety of studies estimate the production of biomass, performs material flow analyses, or addresses supply chain modelling. These studies are often built upon distinct assumptions, tailored to a specific purpose, and often poorly described. This makes comparison amongst studies, generalization of results, or replication hard to even impossible. This paper presents a comprehensive methodology for wood-based biomass material flow analysis, anchored in Material Flow Analysis, built upon literature review and deducted through systematization of previous studies. This is a five-step approach, consisting of (1) adopt proper terminology; (2) obtain accurate estimates for the biomass flows; (3) Sankey diagram for resource balance representation; (4) scenario analysis; (5) stakeholders validation. The focus is to provide instructions for producing a generalized Sankey diagram, from the categorization of biomass resources, uses/applications in a circular economy setting, towards the development of scenario analysis. Its practical implementation is presented by defining the yearly wood-based biomass resource balance of Portugal and the waste wood resource balance of Flanders. The main data sources for the quantification of the biomass sources and uses/applications are identified. Based on the insights from these case studies, our methodological approach already shows to be replicable and with comparable results. This enables the comparison of resource flows between different regions and countries and also monitoring the progress over time. This leads to improved data which can be instruments for supporting companies’ decision-making processes (e.g., infrastructure investments or other strategic decisions), as well as designing policy strategies and incentives.

The ancient lakes Mikri Prespa and Megali Prespa are located in SE Europe at the transnational triangle and are globally recognized for their ecological significance. They host hundreds of flora and fauna species, and numerous types of habitat of conservational interest. They also provide a variety of ecosystem services. Over the last few decades, the two lakes have been interconnected through a surface water channel. In an attempt to explore whether such a management practice might alter the ecological properties of the two lakes, we investigated a series of community metrics for phytoplankton by emphasizing cyanobacteria. Our results demonstrate that the cyanobacterial metacommunity structure was affected by directional hydrological connectivity and high dispersal rates, and to a lesser extent, by cyanobacterial species sorting. Cyanobacterial alpha diversity was twofold in the shallow upstream Lake Mikri Prespa (Simpson index average value: 0.70) in comparison to downstream Lake Megali Prespa (Simpson index average value: 0.37). The cyanobacterial assemblage of the latter was only a strict subset of that in Mikri Prespa. Similarly, beta diversity components clearly showed a homogenization of cyanobacteria, supporting the hypothesis that water flow enhances fluvial translocation of potentially toxic and bloom-forming cyanobacteria. Degrading of the water quality in the Lake Megali Prespa in anticipation of improving that of the Lake Mikri Prespa is an issue of great concern for the Prespa lakes’ protection and conservation.
