Mangroves are ecologically important and extensive in the Neotropics, but they are visibly threatened by selective logging and conversion to pastures in the Southern Caribbean. The objective of this paper was to summarize the impacts of both threats on forest structure, species composition, aboveground biomass and carbon reservoir, species introgressions, and benthic fauna populations by collating past and current data and by using an interdisciplinary approach in the Urabá Gulf (Colombia) as a case study. Mangroves in the Eastern Coast have been decimated and have produced unskewed tree-diameter (DBH) distributions due to the overexploitation of Rhizophora mangle for poles (DBH range: 7–17 cm) and of Avicennia germinans for planks and pilings (DBH >40 cm). Selective logging increased the importance value of the light-tolerant white mangrove Laguncularia racemosa, also increasing biomass and carbon storage in this species, thus offsetting reductions in other species. Introgressions (cryptic ecological degradation) by L. racemosa and Acrostichum aureum (mangrove fern) and low densities of otherwise dominant detritivore snails (Neritina virginea) were observed in periurban basin mangroves. Finally, basin mangroves were more threatened than fringing mangroves due to their proximity to expanding pastures, villages, and a coastal city.

This article aims to encourage the interdisciplinary study of ‘languaculture,’ an approach to language and culture in which ideology, linguistic and cultural forms, as well as praxis are studied in relation to one another. An integrated analysis of the selection of linguistic and cultural elements provides insight into how these choices arise from internalized norms and values, and how people position themselves toward received categories and hegemonic ideologies. An interdisciplinary approach will stimulate a rethinking of established concepts and methods of research. It will also lead to a mutual strengthening of linguistic, sociolinguistic, and anthropological research. This contribution focuses on Limburg and the linguistic political context of this Southern-Netherlands region where people are strongly aware of their linguistic distinctiveness. The argument of the paper is based on a case study of languaculture, viz. the carnivalesque song ‘Naar Talia’ (To Italy) by the Getske Boys from the city of Heerlen.

Social Networks (SNs) bring new types of privacy risks threats for users; which developers should be aware of when designing respective services. Aiming at safeguarding users’ privacy more effectively within SNs, self-adaptive privacy preserving schemes have been developed, considered the importance of users’ social and technological context and specific privacy criteria that should be satisfied. However, under the current self-adaptive privacy approaches, the examination of users’ social landscape interrelated with their privacy perceptions and practices, is not thoroughly considered, especially as far as users’ social attributes concern. This study, aimed at elaborating this examination in depth, in order as to identify the users’ social characteristics and privacy perceptions that can affect self-adaptive privacy design, as well as to indicate self-adaptive privacy related requirements that should be satisfied for users’ protection in SNs. The study was based on an interdisciplinary research instrument, adopting constructs and metrics from both sociological and privacy literature. The results of the survey lead to a pilot taxonomic analysis for self-adaptive privacy within SNs and to the proposal of specific privacy related requirements that should be considered for this domain. For further establishing of our interdisciplinary approach, a case study scenario was formulated, which underlines the importance of the identified self-adaptive privacy related requirements. In this regard, the study provides further insight for the development of the behavioral models that will enhance the optimal design of self-adaptive privacy preserving schemes in SNs, as well as designers to support the principle of PbD from a technical perspective.

This essay explores the interdisciplinary origins and historiography of early North American scholars approaching territoriality – political control of territory – from an indigenous perspective in their works. Using the Ndé (Apaches) as a case study, it reveals how adopting an interdisciplinary approach that addresses territoriality from multiple perspectives can further our understanding of cultural contestation across the continent and hemisphere by highlighting the ways indigenous peoples negotiated, resisted, and adapted to European conquest.

Background Because of the demographic change, lower extremity peripheral artery disease (PAD) is becoming increasingly relevant with respect to health economics. PAD patients often suffer from multiple diseases. Consequently, therapy is commonly complex and requires an interdisciplinary approach. Because of rapid technical developments, interventional endovascular therapy regimens play an increasingly important role. Method Review and literature search on the basis of the current German S3 guidelines on the therapy of PAD as well as international guidelines. In terms of state-of-the-art therapies, relevant current studies were considered. Results Knowledge of existing guidelines and recommendations as well as new therapeutic approaches is essential for the adequate therapy of PAD patients. A close cooperation between the interventional radiologist and the vascular surgeon is the key to success. In addition to established conservative approaches and invasive bypass surgery, the endovascular approach has been a mainstay in the TASC A and B environment for years. It has recently shown promising results in advanced PAD conditions, such as TASC C and D. An endovascular-first strategy is defined in most guidelines. Conclusion A primarily endovascular-first strategy has become the standard in the majority of even complex lesions of the lower extremity arterial system. Regarding the crural segment, a decrease in mortality compared to bypass surgery has been demonstrated. Further evidence can be expected from ongoing randomized multicenter trials.

The recording, documentation and promotion of local cultural heritage has been the subject of significant research from scientists from various fields such as architecture, anthropology, history, folklore, ethnomusicology, and museology. This paper argues that digital technologies could have a catalytic role concerning the operational part of a holistic–interdisciplinary approach to the maintenance of cultural heritage. Simultaneous and bidirectional recording, documentation and promotion of human histories, material elements of space, personal and collective memories, music, dance, singing and other performances, customs, traditions etc. has the effect of improving the understanding of each place and, therefore, contributing to the establishment of sustainable living conditions and environmental balance. At the same time, it facilitates the process of presenting the place’s local identity as well as its tangible and intangible cultural heritage. The paper proposes the design, the creation and the pilot operation of a glocal hybrid (physical and digital) participatory system for monitoring cultural heritage, which consists of (a) spatial recording and projection constructions (open micro-labs); (b) research and documentation centers; and (c) digital databases and mobile applications for interconnection and diffusion of digital content. The system’s implementation domain is considered to be “historic urban landscapes”, i.e., geographical areas with particular cultural features such as traditional settlements, monuments and historical centers, regarded as exceptional universal heritage. In particular, the project’s prime exemplary pilot setup is considered to be operated in specific Greek areas of cultural importance.

Over the last few decades, many countries, especially Caribbean island ones, have been challenged by the devastating consequences of natural disasters, which pose a significant threat to human health and safety. Timely information related to the distribution of vulnerable population and critical infrastructure are key for an effective disaster relief. OpenStreetMap (OSM) has repeatedly been shown to be highly suitable for disaster mapping and management. However, large portions of the world, including countries exposed to natural disasters, remain unmapped. In this study, we propose a methodology that relies on remotely sensed measurements (e.g. VIIRS, Sentinel-2 and Sentinel-1) and derived classification schemes (e.g. forest and built-up land cover) to predict the completeness of OSM building footprints in three small island states (Haiti, Dominica and St. Lucia). We find that the combinatorial effects of these predictors explain up to 94% of the variation of the completeness of OSM building footprints. Our study extends the existing literature by demonstrating how remotely sensed measurements could be leveraged to evaluate the completeness of OSM database, especially in countries at high risk of natural disasters. Identifying areas that lack coverage of OSM features could help prioritize mapping efforts, especially in areas vulnerable to natural hazards and where current data gaps pose an obstacle to timely and evidence-based disaster risk management actions.

As one explanation for the longevity and centrality of lay midwifery in southern childbirth culture, chapter 11 focuses on the lack of medical support and hospital facilities available to African Americans in the Jim Crow South. It reaches back to the early twentieth century and examines the challenges faced by black medical schools and hospitals, and the establishment of the National Medical Association. The problems associated with segregated facilities and the consequences of the Hill-Burton Act failed to ease the pressures on the black medical profession. The Slossfield Community Center in Birmingham Alabama is used as a case study to emphasize the both the obstacles faced by black hospitals and physicians, and the benefits of a holistic, interdisciplinary approach to wellness.
