Tourism & development: concepts and issues
2016
In this interesting book, Richard Sharpley and David Telfer edit 16 chapters that discuss the role of tourism as a facilitator of development for third-world. Though this classic work was already p...
Being lost: tourism, risk and vulnerability in the post-‘9/11’ entertainment industry
2012
This study explores the ways in which the post-‘9/11’ film industry employs tourism as a plot that re-creates mythical imageries of the ‘West’ in relation to a radical ‘other’. Reflecting on sociological and psychological concepts of ‘vulnerability’ and ‘risk’, the authors undertake a content analysis of four ‘horror’ or ‘terror’ films and reveal complex discourses linked to nationalist sentiment, political ideology, the power of expertise and public insecurity in the post-‘9/11’ USA. One interesting feature of the current horror-movie genre is the extent of violence and sadism exerted on Western tourists going abroad. Drawing on the image of the tourist as victim, the authors further discu…
Tourism livelihoods in Smøla, Norway
2017
Tourism in islands and archipelagos provides numerous advantages and disadvantages. This paper analyses a previously unpublished case study of island tourism livelihoods from the archipelago of Smøla, Norway, examining the pros and cons of implemented or proposed tourism livelihoods based on a snapshot from 2008-2009. Smøla’s tourism livelihoods are categorised by nature, technology focusing on the wind farm, fishing and hunting, cultural landscapes, culture, and history. As with many other island and archipelago case studies, the most suitable approach could be tourism-supplemented, rather than tourism-dependent, livelihoods with the principal challenge being finding the right scale for Sm…
L'uomo e il suo ambiente nella Grecia antica: per una "ecopoiesi"
2017
The modern concept of “nature” was born in the XVIIIth Century: a nature as object, submitted to man’s reason. A long traditon sees the origin of the modern notion of nature in the Greek phúsis. To go from phúsis invites us on the contrary to be critical towards the modern paradigm of a nature opposed to culture. Actually the domination of nature and the exploitation by man of what are for us “natural resources” is at the core of the ideological, economical and financial model imposed on us by neoliberal capitalism. This model shapes and destroys the communities of men as well as their environments. To face anthropologically the Greek phúsis invites us to break off with a technological capi…
The allelopathic capacity of submerged macrophytes shapes the microalgal assemblages from a recently restored coastal wetland
2013
Abstract We have tested the efficiency of isolated and combined submerged macrophyte cultures to inhibit, through allelopathy, the natural phytoplankton growth. Both plants and microalgae come from the same wetland, a recently restored area in Albufera de Valencia Natural Park (Spain). The need to replant the area under restoration with submerged macrophytes makes this information essential for wetland management. The selection and culture of the submerged macrophytes used in that restoration (four charophytes: Chara hispida , Chara vulgaris , Chara baltica , Nitella hyalina , and one angiosperm: Myriophyllum spicatum ) provided a good opportunity to test in the laboratory the allelopathic …
Wood-inhabiting fungal responses to forest naturalness vary among morpho-groups
2021
The general negative impact of forestry on wood-inhabiting fungal diversity is well recognized, yet the effect of forest naturalness is poorly disentangled among different fungal groups inhabiting dead wood of different tree species. We studied the relationship between forest naturalness, log characteristics and diversity of different fungal morpho-groups inhabiting large decaying logs of similar quality in spruce dominated boreal forests. We sampled all non-lichenized fruitbodies from birch, spruce, pine and aspen in 12 semi-natural forest sites of varying level of naturalness. The overall fungal community composition was mostly determined by host tree species. However, when assessing the …
Functional correlation of genome-wide DNA methylation profiles in genetic neurodevelopmental disorders
2022
An expanding range of genetic syndromes are characterized by genome-wide disruptions in DNA methylation profiles referred to as episignatures. Episignatures are distinct, highly sensitive and specific biomarkers that have recently been applied in clinical diagnosis of genetic syndromes. Episignatures are contained within the broader disorder-specific genome-wide DNA methylation changes which can share significant overlap amongst different conditions. In this study we performed functional genomic assessment and comparison of disorder-specific and overlapping genome-wide DNA methylation changes related to 65 genetic syndromes with previously described episignatures. We demonstrate evidence of…
Investigating a simplified method for noninvasive genetic sampling in East African mammals using silica dried scat swabs
2020
Abstract Swabbing scat has proved to be an effective noninvasive method to collect DNA from mammals in the field. Previously, this method has relied on preservative liquids or freezing to preserve the DNA collected on swabs. In this study, we determine the effectiveness of using silica to simply dry the swab in field as an alternative way to prevent DNA degredation. Four species were included in the study; reticulated giraffe, impala, fringe‐eared oryx, and lion. Swabs were taken at multiple time points for giraffe and impala scat samples, with the lion and oryx sampled opportunistically. Mitochondrial DNA was successfully amplified and sequenced from scat swabs from all species; however, e…
Growth form matters – Crustose lichens on dead wood are sensitive to forest management
2022
Lichens have a vital role in forest ecosystems and they are a threatened group in boreal forests. However, the conservation ecology of the total lichen community has very rarely been studied. Here we studied lichen species and communities, including macrolichens (=foliose and fruticose growth forms) and rarely studied crustose li-chens, on decaying wood in boreal spruce-dominated forests in Finland. We also studied obligate lignicoles that grow only on dead wood and are mostly crustose in growth form. Species richness and community composition were examined on decaying logs and natural or cut stumps of Picea abies at different decay stages (2-5) in 14 stands, half of which were natural or s…
Heritage and knowledge: apparatus, logic and strategies in the formation of heritage
2016
Heritage as a category reflects diverse political positions. All heritagisation processes imply the creation of hierarchies, selection, ranking, and categorization of what is worthy or unworthy of being heritage, and all heritage creation involves certain disciplinary processes that confer legitimacy. As a modern invention, heritage was built on two closely-related cornerstones: the distinction between nature and culture and the difference between normalized knowledge and marginal knowledge. As a result, refining processes were applied which became strategies to legitimise political domination. In this paper the constituent process of heritage creation and its links to normative knowledge a…
