Lorenz Heister and the challenge of trepanation: a neurosurgical case study from the 18th century

In the 18th century, medical practice was essentially based on communication. Cranial trepanation, however, was usually performed on an unconscious person. Here the dialogue ceased. It was the only operation which had to be attempted without the positive consent of the patient. Thus trepanation challenged the surgeon's skill not only with its intricate surgical practice, but also with its unusual social setting. The present paper illustrates possible ways out of the "trap of trepanation" by interweaving two points of view. On the one hand, a general account is given on the basis of surgical publications written by Lorenz Heister and his contemporaries. On the other, the unpublished sources of the Heister correspondence serve to reconstruct the case of Heinrich Wilhelm Bachmann, a German merchant who fell victim to a traffic accident and underwent trepanation in 1753. The case study shows how the physician in charge counterbalanced the patient's inability to communicate by strengthening the remaining network of professionals, and ultimately confirming his decisions by use of the post-mortem.     

COVID-19 is expanding global consciousness and the sustainability of travel and tourism

Abstract

The sustainable development model has largely failed to address the social and environmental challenges of the 21^st century. True sustainability will only occur when it is valued as a part of the taken-for-granted daily life of individuals and cultures across the globe. This has not yet happened because humanity has not evolved a global consciousness quickly enough to match the global advances in telecommunications and transportation technologies that have created a socially and economically ever-shrinking planet. Travel and tourism contributes to the expansion of global consciousness, although only in a haphazard and unintentional manner. The COVID-19 pandemic is a result of planetary time-space compression and is forcing an expansion in human consciousness that will make humankind better able to address global problems. There will still be considerable diversity on the planet, as now, but the pandemic will stimulate growing numbers of people, businesses and governments to adopt new ways of thinking, behaving and operating that are more closely aligned with the goals of sustainable development. This could be further enhanced if travel and tourism were to adopt the expansion and awakening of global conscious as a fundamental and transformational value in the products and experiences that it offers.     

Nationalising indigenous peoples,legalising indigenous lands: a (post)colonial critique of the land demarcation process in Brazil by the analysis of the Guarani-Mbyá case

The Brazilian 1988 constitution recognises indigenous peoples as ‘first and natural owners of Brazilians land’ and the 231st Article ensures their right to special territories where they could live their culture and traditions without colonising presence. The authentication of these territories, however, requires Public Power promotion, which lies on colonising, juridical accounts and depends on anthropological, scientifically historical research. Our argument here is that the bureaucratisation of the land demarcation process is only possible within a context of epistemological advantage of science, i.e. modernity, which ignores indigenous territory and time conceptions. We will also argue that this bureaucratisation has been contributing to the (neo)colonisation of the territory by retarding the recognition and protection of indigenous rights.     

Long-distance provenance for obsidian artifacts of Mesoamerica Preclassic and Early Classic periods found in the Los Naranjos Archaeological Park (Honduras)

Los Naranjos is one of the most important pre-Columbian human settlements of Honduras related to the south-easternmost border of the Mayan civilization. Although the archaeological site mostly spans from 850 BC to 1250 AD, the present obsidian study was only focused on the Preclassic and Early Classic periods (Jaral, 800–400 BC and Edén, 400 BC–550 AD) where undamaged blades and/or retouched obsidian flakes are rare. In this way, the INAA analyses of 17 obsidian samples, compared with major-trace elements data of Honduran and Guatemalan obsidian sources, are mostly representative of waste flakes. Lithic artifacts of Los Naranjos such as sandstones, basalts, and quartzites come from local geological outcrops; whereas, obsidian provenance has to be searched from sources which are located within a radius up to 300 km far away. San Luis, La Esperanza, and Güinope obsidian sources are located in Honduras while the three most exploited Highland Guatemalan obsidian outcrops, which have been dominating long-distance trade in the Maya area mostly for the Classic-Postclassic periods, are San Martin de Jilotepeque, El Chayal, and Ixtepeque. An Ixtepeque provenance, for all the investigated obsidian samples of Preclassic and Early Classic periods found in the Los Naranjos Archaeological Park, was established, thus emphasizing a long-distance source (180 km). This also confirms that Ixtepeque represents the most important provenance of the obsidian artifacts found in archaeological sites of Western and Central-Western Honduras. The possible role played by some of the most important rivers of Guatemala and Honduras as waterway networks of transport was finally pointed out. New INAA chemical data from the Honduran obsidian source of La Esperanza (“Los Hoyos”, 4 samples) are also reported in this paper.     

Governance in Multi-Project Networks: Lessons from a Failed Destination Branding Effort

Abstract

This article describes and analyses the process in which the establishment of a Christmas market led to an attempt to establish a regional destination brand named “Delightful Christmas”. Our focus is on the network dynamics of the process, in particular its multi-project network characteristics. Empirical findings are based on qualitative data from personal interviews, participant observation and documentation in an action research approach. The process is analysed as a so-called project network (Hellgren & Stjernberg, 1995 Hellgren, B. & Stjernberg, T. (1995) Design and implementation in major investments—a project network approach, Scandinavian Journal of Management, 11(4), pp. 377–394. doi: 10.1016/0956-5221(95)00020-V[Crossref] , [Google Scholar]) involving different actors having different aims in event and destination brand development, thus creating a process with actors of existing, but resource-lacking, dependencies. Despite the disagreements between actors, the common beliefs and hopes for the integrated destination theme remained and innovative work continued for about three years in an environment where conditions were difficult due to insufficient financial resources, project coordination and long-term strategic planning. Conclusions concern the dynamics of a complex multi-project network organization and how its failure can be explained.
