Using either freshly pulped or preserved seaweed biomass for the extraction of protein can have a great effect on the amount of protein that can be extracted. In this study, the effect of four preservation techniques (frozen, freeze-dried, and air-dried at 40 and 70 °C) on the protein extractability, measured as Kjeldahl nitrogen, of four seaweed species, Chondrus crispus (Rhodophyceae), Ascophyllum nodosum, Saccharina latissima (both Phaeophyceae) and Ulva lactuca (Chlorophyceae), was tested and compared with extracting freshly pulped biomass. The effect of preservation is species dependent: in all four seaweed species, a differenttreatment resulted in the highest protein extractability. The pellet (i.e., the non-dissolved biomass after extraction) was also analyzed as in most cases the largest part of the initial protein ended up in the pellet and not in the supernatant. Of the four species tested, freeze-dried A. nodosum yielded the highest overall protein extractability of 59.6% with a significantly increased protein content compared with the sample before extraction. For C. crispus extracting biomass air-dried at 40 °C gave the best results with a protein extractability of 50.4%. Preservation had little effect on the protein extraction for S. latissima; only air-drying at 70 °C decreased the yield significantly. Over 70% of the initial protein ended up in the pellet for all U. lactuca extractions while increasing the protein content significantly. Extracting freshly pulped U. lactuca resulted in a 78% increase in protein content in the pellet while still containing 84.5% of the total initial total protein. These results show the importance of the right choice when selecting a preservation method and seaweed species for protein extraction. Besides the extracted protein fraction, the remainingpellet also has the potential as a source with an increased protein content.

Coastal and marine cultural heritage (CMCH) is at risk due to its location and its often indefinable value. As these risks are likely to intensify in the future, there is an urgent need to build CMCH resilience. We argue that the current CMCH risk management paradigm narrowly focuses on the present and preservation. This tends to exclude debates about the contested nature of resilience and how it may be achieved beyond a strict preservationist approach. There is a need, therefore, to progress a broader and more dynamic framing of CMCH management that recognises the shift away from strict preservationist approaches and incorporates the complexity of heritage’s socio-political contexts. Drawing on critical cultural heritage literature, we reconceptualise CMCH management by rethinking the temporality of cultural heritage. We argue that cultural heritage may exist in four socio-temporal manifestations (extant, lost, dormant, and potential) and that CMCH management consists of three broad socio-political steering processes (continuity, discontinuity, and transformation). Our reconceptualisation of CMCH management is a first step in countering the presentness trap in CMCH management. It provides a useful conceptual framing through which to understand processes beyond the preservationist approach and raises questions about the contingent and contested nature of CMCH, ethical questions around loss and transformation, and the democratisation of cultural heritage management.

The shallow subsurface in historic cities often contains extensive archaeological remains, also known as cultural deposits. Preservation conditions for naturally degradable archaeological remains are strongly dependent on the presence or absence of groundwater. One of the main goals at such heritage sites is to establish a stable hydrological environment. Green infrastructural solutions such as Sustainable Urban Drainage Systems (SUDS) can support preservation of cultural deposits. Several cases show that implementation of SUDS can be cost effective at preservation of cultural deposits. These include Motte of Montferland, City mound of Vlaardingen, Weiwerd in Delfzijl, and the Leidse Rijn area. In all cases, the amount of underground infrastructure is minimised to prevent damaging cultural layers. SUDS have been implemented to preserve cultural heritage. The first monitoring results and evaluation of the processes give valuable lessons learned, transnational knowledge exchange is an important element to bring the experiences across boundaries.

In this article, the preservation of the monumental built environment from the colonial period is related to and discussed within the perspective of heritage ownership. It contributes to a debate in which heritage resource preservation is approached and connected to several heritage ownership issues. It argues that an effective built environmental preservation policy for colonial heritage is strongly related to and dependent on issues such as legal property ownership, legislation on listed buildings, enforcement of such legislation, and the willingness among different categories of potential owners to participate and support such preservation. Especially, when it comes to built colonial heritage as an imported alien resource from a colonial past, these issues are particularly interesting and sensitive. A good illustration of these issues is the case of Paramaribo, Suriname. The national government policy following the inscription of the historic inner city of Paramaribo on the World Heritage List of UNESCO in 2002 clearly demonstrates an area of tension and difficulty between and within the interested parties. It shows that monumental preservation and heritage management and interpretation are strongly affected and determined by concepts such as ownership, affinity, interest, economic priorities, and political will. By referring to the actual problems encountered in the preservation efforts relating to the built colonial heritage in Paramaribo and subsequently explaining these problems in relation to specific ownership issues, this article throws light on a number of dilemmas. Conclusions are drawn widening the argument and contributing to the ongoing debate on heritage ownership issues and monument preservation policies especially as it relates to the global issue of managing the relics of now defunct empires. In recent years an increasing interest can be detected in issues concerning the legal property ownership of heritage. This growth in interest focuses in particular on the legislation in relationship to property ownership issues. An important aim of national governments is to use legislation to safeguard their cultural property by embedding it in law, especially, when this cultural property has a high monetary or identity value (as stressed by Fechner, 1998). Additionally, the growing awareness and recognition of heritage as a valuable economic, sociopsychological and environmental asset is receiving increasing international attention. For example, the international acknowledgment that heritage resources are under pressure from all kinds of processes and impacts has encouraged the need for an extension of international legal measures. Consequently, this international interest, often expressed in conventions, charters, and treaties, encourages national and local initiatives (Techera, 2011). An interesting complication to this issue is the question that arises where it involves the monumental built environment from the colonial period that is being preserved and restored, as it may be viewed as a heritage based on alien resources. In particular the acceptance, recognition, and role of what may be viewed as an imported colonial built environment in a multicultural and multiethnic context, may impact effective legislation. Although the discussion about the roles of heritage within a plural cultural and ethnic society has already begun (recently emphasized by Van Maanen, 2011; Ashworth, Graham, & Tunbridge, 2007), it is still an underresearched topic when it comes to legal property ownership as part of a management strategy for preserving built colonial heritage resources. This article examines in particular the effectiveness of policies and laws pursued in Suriname as an instrument for the preservation of resources. It highlights the legal and administrative challenges facing the implementation, management, and enforcement of these strategies and measures. The first part of this article examines the debate about the approach and strategy in using law in conservation and preservation policies. Then the article proceeds to introduce Suriname as an instructive case study. It describes the existing multiethnic context of Suriname and the evolution of legislative policy for the historic inner city of the capital, Paramaribo, with its monumental built environment from the colonial period. By using field data, the article continues with an analysis of the effectiveness and impacts of this administrative and legal framework established in Suriname. It examines in detail the main problems encountered and the extent to which this strategy is supported by the key stakeholders.

Indigenous tourism plays a crucial role in sustainable development, cultural heritage preservation, and social equity. However, the integration of innovation in Indigenous tourism remains fragmented and underexplored. This research employs the Theory, Context, Characteristics, and Methodology (TCCM) framework to systematically review 131 studies from major academic databases, offering the first comprehensive analysis of innovations in Indigenous tourism. The findings highlight China as a leading contributor in this field, emphasizing incremental innovations and their social and economic impacts. Despite progress, critical areas such as well-being, education, community empowerment, and environmental impacts remain underrepresented. To address these shortcomings, the study proposes ten propositions to advance theoretical and practical understanding in the sector. These insights guide future research and policy-making, strengthening Indigenous tourism's capacity to foster sustainable development, protect cultural heritage, and empower communities while addressing existing challenges in implementing innovations.

By supporting creation of protected areas, conservation projects are known to bring economic prosperity to the local communities, but also incite criticism. A common theme in the critique of conservation organizations is the proximity to neoliberal agencies seeking to capitalize on environment, which disadvantage the local communities. Community participation has been proposed as a panacea for neoliberal conservation. However, conservation efficacy is not always contingent on the community involvement and reliance on ‘traditional’ practices in protected areas has not always benefitted biodiversity. Simultaneously, critique of conservation ignores evidence of indigenous activism as well as alternative forms of environmentalism which provide a broader ethical support base for conservation. This article highlights the challenges and contradictions, as well as offers hopeful directions in order to more effectively ground compassionate conservation. https://doi.org/10.1080/23251042.2015.1048765 https://www.linkedin.com/in/helenkopnina/

Social scientists of conservation typically address sources of legitimacy of conservation policies in relation to local communities’ or indigenous land rights, highlighting social inequality and environmental injustice. This chapter reflects on the underlying ethics of environmental justice in order to differentiate between various motivations of conservation and its critique. Conservation is discussed against the backdrop of two main ethical standpoints: preservation of natural resources for human use, and protection of nature for its own sake. These motivations will be examined highlighting mainstream conservation and alternative deep ecology environmentalism. Based on this examination, this chapter untangles concerns with social and ecological justice in order to determine how environmental and human values overlap, conflict, and where the opportunity for reconciliation lies, building bridges between supporters of social justice and conservation. https://www.springer.com/gp/book/9783319713113#aboutBook LinkedIn: https://www.linkedin.com/in/helenkopnina/

The advent of information and communication technologies (ICTs) has had and is having a major impact on Indonesian cultural resource management, and on the safeguarding methods of its tangible and intangible cultural heritages. Despite varied levels and visible gaps between rural and urban regions in terms of technology usage, innovative initiatives have been created, which correspond to the needs and expectations of a technology-savvy public. As a starting point, a number of public institutions dealing with tangible cultural heritage (e.g. museums, palaces, temples, World Heritage Sites (WHS) do use innovative digital tools in order to communicate to various audiences, as well as to enrich visitors' experience, especially taking into consideration young generations. This paper will firstly examine the role of ICTs in intangible cultural heritage (ICH) (e.g. Batik, Wayang puppet theatre, etc.); secondly, the authors will explain how ICTs can help to communicate and promote the values, history, and significances of ICH products, both for locals and tourists, with the goal of raising awareness on cultural identity. However, the knowledge of ICH still requires contacts with its own communities and is vulnerable, as it can be exposed to excessive cultural commoditization through e-platforms. This study aims at giving an overview and some examples of digital interventions for cultural heritage communication implemented by various stakeholders in Indonesia. In addition, this paper analyses to what extent a participatory approach engaging local communities, academics, private sectors, NGOs and the government, can ensure higher levels of effectiveness and efficiency, hence supporting the conservation of UNESCO tangible/ICH in Indonesia. This paper aims at: (1) presenting the development of digital heritage platforms in Indonesia; (2) providing a grid of analysis of digital heritage knowledge platforms dedicated to UNESCO tangible and ICH in forms of websites and mobile apps.

BackgroundUnderstanding cultural perceptions of illness is crucial for effective healthcare delivery. This study examines the ethnomedical concept of ikirimi, a culturally recognized illness in Rwanda characterized by perceived uvula abnormalities, and its traditional management through uvulectomy. This study explores the cultural understanding of ikirimi, its perceived causes, symptoms, and treatments, as well as barriers to integrating modern healthcare.MethodsAn exploratory qualitative approach was employed, involving in-depth semi-structured interviews with eight participants: traditional healers, individuals who underwent traditional uvulectomy, and healthcare providers. A grounded theory approach which analyzes data in systematic manner to generate new theories was applied, with coding conducted in English after initial transcription and analysis in Ikinyarwanda to preserve Indigenous concepts.ResultsParticipants described ikirimi as an illness affecting the uvula (named as akamironko or akamirabugari or agashondabugari in Ikinyarwanda), characterized by swelling, elongation, and pus-like discoloration. Reported symptoms included fever, difficulty swallowing, coughing, and weakness, with children identified as the most affected group. Traditional healers diagnosed ikirimi through visual inspection of uvular morphology and movement and treated it by cutting the affected part of uvula and is known as guca Ikirimi ‘traditional uvulectomy’. Barriers to integrating modern healthcare included skepticism about biomedical care, judgmental attitudes from providers, and communication gaps. Despite the prevalence of ikirimi, its biomedical correlates remain unclear, though participants associated it with severe throat illnesses such as tonsillopharyngitis.ConclusionThe findings highlight ikirimi as a socially constructed illness with deep cultural roots, significant health implications, and persistent barriers to modern healthcare. Addressing these barriers requires culturally sensitive approaches that integrate Indigenous knowledge with biomedical practices. Future research should explore the biomedical correlates of ikirimi and foster collaboration between traditional and modern healthcare systems to improve patient outcomes.

This publication gives an account of the Public Annotation of Cultural Heritage research project (PACE) conducted at the Crossmedialab. The project was carried out between 1 January 2008 and 31 December 2009, and was funded by the Ministry of Education, Culture, and Science. Three members of the Dutch Association of Science Centres (Vereniging Science Centra) actively participated in the execution of the project: the Utrecht University Museum, the National Museum of Natural History (Naturalis), and Museon. In addition, two more knowledge institutes participated: Novay and the Utrecht University of Applied Sciences. BMC Consultancy and Manage¬ment also took part in the project. This broad consortium has enabled us to base the project on both knowledge and experience from a practical and scientific perspective. The purpose of the PACE project was to examine the ways in which social tagging could be deployed as a tool to enrich collections, improve their acces¬sibility and to increase visitor group involvement. The museums’ guiding question for the project was: ‘When is it useful to deploy social tagging as a tool for the benefit of museums and what kind of effect can be expected from such deployment?’ For the Crossmedialab the PACE project presented a unique opportunity to conduct concrete research into the highly interesting phenomenon of social tagging with parties and experts in the field.
