Like its ancestral disciplines, archaeology is no stranger to human conflict. Greek and Roman warfare often resulted in the sacking of cities, with all property (public, private, temple) taken as booty and the population and heritage exterminated or absorbed (men killed, women and children sold into slavery). In addition to the personal danger risked in a hostile region, archaeologists may also be thrust into deep and divisive cultural embattlements. Cultural property may be destroyed, intentionally or unintentionally. Graves, including potential evidence of genocide or mass murder, may be disturbed. Archaeologists may find themselves embroiled in many of these disputes and violent events, leading to difficult and complex ethical issues. This viperous nest of ethical concerns is amplified where an archaeologist is present as part of, or perceived to be related to, an invading or occupying military force. The goal of this thesis is to develop an engaging and pragmatic virtue-based professional ethic that may guide an archaeologist and archaeology through the ethical bramble bush raised by modern human conflict. The present ethical systems, based primarily on utilitarian or deontological principles manifested in ethical codes, are deficient because they fail to establish the archaeologist as a trustee (active or passive) in a political dynamic, elevate the archaeological record even when these professional codes purport to discount its importance, fail to address adequately the matrix of relationships in a manner that ensures trust across the interests of all stakeholders – both present and past, and dramatically fail to identify and develop the central thrust of a professional ethic (as opposed to personal moral judgment) in the first instance.

This work primarily examines the management of wet-preserved archaeological sites in England, through an exploration of value and analysis of current management approaches. The aim is to explore whether the current policy frameworks, in particular the role of preservation in situ, can provide a sustainable future for wet-preserved archaeological sites. This work further seeks to conceptualise the modelling of sustainability, preservation and management decision making in wetland archaeological sites. Looking at the last 40 year of wetland research through the work of the large-scale wetland survey projects, this work initially considers the current understanding of wet archaeological sites in England. It also examines aspects of heritage management through the legislative and policy frameworks and their legacy. This work considers the implications that legislative and policy positions have for the management of wetland archaeological sites and examines the theoretical concepts that underpin them. This includes exploring reflective management, the development of research frameworks, and scoring mechanisms for the designation of sites. It also looks at broader constructs of value through the concepts of cultural and economic values. Three existing archaeological sites, a ringwork at Borough Fen near Peterborough, a marsh fort at Sutton Common near Doncaster and a triple post-alignment near Beccles, will be presented as case studies. These sites serve as examples of how the management of sites has been approached. The results of the case study analysis are used to develop a series of conceptual models looking firstly at sustainability and preservation in situ, and, secondly at preservation, value and decision making. The study concludes that the presumption in favour of preservation in situ can be challenging for wet preserved archaeological sites. Deterioration of the preservation environment can in some cases produce a similar decline in significance. Preservation in situ may therefore not be the most appropriate option for archaeological sites in wetlands.

The Monuments at Risk Survey 1995 (MARS) outlined rates and causes of identified monument loss in England, showing that 16% of recorded monuments had been completely destroyed by 1995, and that 95% of surviving monuments in England had suffered partial destruction. Hitherto, no equivalent research has been undertaken in Scotland. Using a 17% random stratified sample of 779 field monuments surviving in 1850 within a study area encompassing much of the local authority areas of Perth and Kinross, Fife and Angus, the present research has analysed the distribution and quantified loss of archaeological monuments since 1850 in relation to a number of variables including land use, Land Capability for Agriculture, elevation, local authority area, monument period and material construction. Results show that monument distribution within the study area varies most noticeably according to land use and elevation. The highest densities of extant monuments are found in semi-natural woodland (17.2 extant sample monuments per 100km2) and non-intensive land uses such as unimproved grazing and moorland (13.8 extant sample monuments per 100km2). The lowest density of extant monuments is found in arable and improved pasture (4.5 extant sample monuments per 100km2), although this is offset by a recorded density of 11.5 cropmark sample monuments per 100km2. By elevation, monument densities are highest below 100m OD (24.4 monuments per 100km2) and between 250m OD and 400m OD (21 monuments per 100 km2)with a pronounced paucity of recorded monuments between 100m OD and 200m OD, particularly on improved and arable land. For each sample monument, a condition history has been constructed through a desk-based study using data from the National Monuments Record of Scotland. This desk-based study has recorded the greatest causes of monument loss since 1850 as unknown causes (28% of loss), archaeological excavation (24% of loss), farming (15% of loss) and development (11% of loss). The monument condition histories created through the desk-based study have then been augmented and calibrated for a subsample of 258 monuments by means of an accuracy assessment, using information from vertical and oblique aerial photographs, survey reports from Historic Scotland Monument Wardens and a programme of field survey. Using these additional data sources, the accuracy assessment has identified the largest causes of monument loss within the study area since 1850 as forestry (31% of loss), farming (28% of loss) and development (12% of loss). Analysis shows that among monuments extant in 1850, a minimum of 38% have been reduced in extent, with at least 5% destroyed. Loss has been greatest among monuments found in arable and improved land (39% reduced, 27% destroyed), forestry (79% reduced, 9% destroyed) and developed land (63% reduced, 27% destroyed), and lowest among monuments found in permanent pasture (91% undamaged), semi-natural woodland (75% undamaged) and rough grazing and moorland (85% undamaged). Although the use of a desk-based study and accuracy assessment has proved successful in identifying trends in the loss of visible monuments, it has been necessary to employ alternative methods by which to assess damage at buried monuments represented by cropmarks. To this end, a programme of excavation, topographic survey and soil depth recording has been undertaken at five locations in Perth and Kinross. Analysis of the results from this programme of excavation and survey has identified statistically significant relationships between land surface curvature and topsoil depth at three of the five sites examined, enabling the mapping at site scale of areas which are likely to have been subject to greatest agricultural damage. Extrapolating from these site-specific maps, it has been possible to map probable damage and risk to cropmark monuments at a regional scale. Although the validity of this regional scale mapping has been limited by the 25m cell size of the digital terrain model on which it has been based, the potential of such a technique in enabling a rapid preliminary assessment of damage and risk to cropmark monuments has been demonstrated.

Cardiac transplantation is the treatment of choice for eligible patients with advanced heart failure; however, it is limited by a critical shortage of suitable organs from traditional brain-dead donors. Organs donated following circulatory death (DCD) have been used to successfully expand the pool of organs available for kidney, liver, and lung transplantation; however, concerns regarding the severity of injury sustained by the heart following withdrawal of life sustaining therapy have deterred the clinical transplantation of DCD hearts. Investigations aiming to optimize the resuscitation, preservation, and evaluation of DCD hearts may facilitate the development of an evidence based protocol for DCD heart transplantation that can be translated to the clinical area and expand the donor pool. Therefore, the objectives of this thesis are to develop a clinically relevant large animal model of DCD and gain a greater understanding regarding the physiologic impact of donor extubation on the DCD heart, demonstrate as a ‘proof-of-concept’ that utilizing an approach to donor heart resuscitation, preservation, and evaluation that is tailored to the DCD context can facilitate successful transplantation, and finally to investigate ways to optimize the resuscitation, preservation, and evaluation of DCD hearts for transplantation. The results of this thesis may then be used to inform the development of an evidence-based protocol for DCD heart transplantation that can be translated to the clinical area. The clinical adoption of such a protocol has the potential to expand the donor pool and improve outcomes for patients with end-stage heart failure. / May 2017

Detection and identification of pesticide residues on objects of cultural heritage is a serious and urgent challenge that currently faces many museums, Native American communities, and private collections worldwide. Organic artifact materials, such as wood, animal hide, basketry, textiles, paper, horn and bone, have traditionally been treated with pesticides to eradicate and prevent infestation by insects, rodents, and mold. These poisonous substances can persist for years in the controlled environment of a museum storeroom and present a potential poisoning risk to people who come in contact with the objects. Surface-enhanced Raman spectroscopy (SERS) has the potential to detect volatile organic pesticides in this context. The technique can overcome the insensitivity of normal Raman spectroscopy and fluorescence interference, and make possible detection of many organic compounds in parts per million concentration. This investigation is aimed at evaluating SERS for the detection and identification of volatiles in museums, with emphasis on naphthalene vapor. The potential of several SERS-active materials; Tollens mirrors, gold film over nanosphere arrays, citrate-stabilized colloidal silver, and nanoporous gold; to detect Rhodamine B and naphthalene is investigated. The research also highlights the mechanisms that underlie SERS, and the relationship between substrate nanostructure and SERS performance.

Swedish cultural heritage policies put heritage of the Church of Sweden in an exceptional position. It is protected by law and managed by the Church of Sweden which receives a yearly economical compensation from the Swedish government to assure a continued protection and care. The purpose of this study has been to examine categories and definitions that are used in the formulations of the protection of this part of the national cultural heritage. The study also analyses the values and motives behind the distribution, which is being regulated by said definitions. To achieve this, I have answered questions about to what kind of projects the compensation has been distributed, focusing on the appointed object and intervention categories. These classifications have been compared to the projects actual character, and also to official guidelines and policies. The results of the study show that the distribution of the government compensation follow official guidelines more often than not, but also that the project categorizations are frequently misguiding in comparison to the actual character of the projects. In written statements from the Swedish National Heritage Board and the Church of Sweden a dissonance regarding their respective value perspectives has been shown. The big difference is found in a question of definitions regarding the nature of the religious heritage in policy documents. Definitions of cultural heritage are crucial in heritage management. The classification stated in policy documents and used during the management of the heritage of the Church of Sweden, is also defining what is included. These classifications and definitions are part of the traditional western heritage management discourse. By using theoretical frameworks like Authorized Heritage Discourse the results of the study has been put in a perspective of using categories as way to manifest material heritage. This is a two years master’s thesis in Archive, Library and Museum studies.

Homes are involved in a significant fraction of Internet traffic. However, meaningful and comprehensive information on the structure and use of home networks is still hard to obtain. The two main challenges in collecting such information are the lack of measurement infrastructure in the home network environment and individuals’ concerns about information privacy. To tackle these challenges, the dissertation introduces Home Network Flow Logger (HNFL) to bring lightweight privacy-preserving passive measurement to home networks. The core of HNFL is a Linux kernel module that runs on resource-constrained commodity home routers to collect network traffic data from raw packets. Unlike prior passive measurement tools, HNFL is shown to work without harming either data accuracy or router performance. This dissertation also includes a months-long field study to collect passive measurement data from home network gateways where network traffic is not mixed by NAT (Network Address Translation) in a non-intrusive way. The comprehensive data collected from over fifty households are analyzed to learn the characteristics of home networks such as number and distribution of connected devices, traffic distribution among internal devices, network availability, downlink/uplink bandwidth, data usage patterns, and application traffic distribution.

Behoven av att nyttja gamla ekonomibyggnader i sitt ursprungliga användningsområde har minskat. De gamla husen har dock kvalitéer som är värda att bevara vilket bör betänkas innan de plockas ner eller eldas upp. Denna rapport är en aktionsstudie av ladugårdsbyggnaden på Nygården, Vemdalens Kyrkby 4;5. Projektbyggnaden är en liggtimmerbyggnad från mitten av 1800-talet som för närvarande används som garage och förråd. Ägarna till gården har för avsikt att riva projektbyggnaden och istället uppföra en gäststuga på samma platts. I rapporten avhandlas möjligheten att istället med god byggnadsvård renovera liggtimmerstommen och anpassa ladugården till en modern bostad. I rapporten granskas vilka fördelar det kan innebära att bygga om ladugården istället för att riva den och bygga nytt. För att svara på frågor har olika undersökningsmetoder använts. En okulär besiktning av byggnaden ha genomförts där sakkunnig timmerman gav sin åsikt om stommens kondition och brister. Utifrån besiktning, intervju med ytterligare timmerman och med hjälp av litteraturstudier presenteras ett förslag om åtgärder inom ramen för god byggnadsvård. Diskussion förs angående ombyggnadens lönsamhet med avseende på ekonomi, ekologi och kvalité och jämförs med rivning och nybyggnad. Slutsatsen är att projektbyggnaden lämpar sig för ombyggnad då den är av god kvalité och kondition samt uppförd med en byggnadsteknik som är lämpad för förändring. Utförandet av förändringar och av åtgärder mot brister är relativt enkelt men tidskrävande. Kvalitativa, ekonomiska och ekologiska fördelar som värmetröghet, historia, materialbesparingar samt minskad mängd avfall står att finna. / The need to use old outbuildings in its original use has decreased. The old houses, however, has qualities that are worthy of protection which should be borne in mind before they are teared down. This report is an action study of the barn on Nygården, Vemdalens Kyrkby 4; 5th. The project building is a lug building from the mid-1800s, currently used as garage and storage. The owners of the estate intend to tear down the barn to make space for a new guest house. The report treats the possibility to maintain the barn and rebuild it into a modern residence, within the framework of building preservation. The report examines benefits with rebuilding the barn instead of tearing it down and new produce. Different research methods are used. A visual inspection of the building is done in cooperation with a lug carpenter who gives his opinion on structural conditions. Based on the inspection, an interview with another carpenter and literature studies a proposal on measures, within the framework of building preservation, is presented. Profitability in terms of economy, ecology and quality is discussed and compared with demolition and new production. The conclusion is that the project building is suitable for renovation due to good quality, good condition and it has a construction suitable for change. The measures of change are relatively simple but time consuming. Qualitative, economic and ecological benefits to be find is among other thermal inertia, material consuming savings and reduction of waste.

The evolutionary origins of animal phyla are intimately linked with the Cambrian explosion, a period of radical ecological and evolutionary innovation that begins approximately 540 Mya and continues for some 20 million years, during which most major animal groups appear. Lophotrochozoa, a major group of protostome animals that includes molluscs, annelids and brachiopods, represent a significant component of the oldest known fossil records of biomineralised animals, as disclosed by the enigmatic ‘small shelly fossil’ faunas of the early Cambrian. Determining the affinities of these scleritome taxa is highly informative for examining Cambrian evolutionary patterns, since many are supposed stem-group Lophotrochozoa. The main focus of this thesis pertained to the stem-group of the Brachiopoda, a highly diverse and important clade of suspension feeding animals in the Palaeozoic era, which are still extant but with only with a fraction of past diversity. Major findings include adding support for tommotiid affinity as stem-group lophophorates. Determining morphological character homologies vital to reconstructing the brachiopod stem-group was achieved by comparing Cambrian Lagerstätten with the widespread biomineralised record of Cambrian stem-brachiopods and small shelly fossils. Polarising character changes associated with the putative transition from scleritome organisms to crown-group brachiopods was furthered by the description of an enigmatic agglutinated tubular lophophorate Yuganotheca elegans from the Chengjiang Lagerstätte, China, which possesses an unusual combination of phoronid, brachiopod and tommotiid characters. These efforts were furthered by the use of X-ray tomographic techniques that revealed novel anatomical features, including exceptionally preserved setae in the tommotiid Micrina. The evidence for a common origin of columnar brachiopod shell structures in the tommotiids is suggested and critically examined. Enigmatic and problematic early and middle Cambrian lophotrochozoans are newly described or re-described in light of new evidence, namely: the stem-brachiopod Mickwitzia occidens Walcott from the Indian Springs Lagerstätte, Nevada; a putative stem-group entoproct Cotyledion tylodes Luo and Hu from Chengjiang, China; a new enigmatic family of rhynchonelliform brachiopods exemplified by the newly described Tomteluva perturbata from the Stephen Formation, Canada; and the tommotiid Micrina etheridgei (Tate) from the Flinders Ranges, South Australia. Cladistic analyses of fossil morphological data supports a monophyletic Brachiopoda.
