Exploratory research into supply chain voids within Welsh priority business sectors

The paper reports the findings resulting from the initial stages of an exploratory investigation into Supply Chain Voids (SCV) in Wales. The research forms the foundations of a PhD thesis which is framed within the sectors designated as important by the Welsh Assembly Government (WAG) and indicates local supplier capability voids within their supply chains. This paper covers the stages of initial data gathering, analysis and results identified between June 2006 and April 2007, whilst addressing the first of four research questions. Finally, the approach to address future research is identified in order to explain how the PhD is to progress

Implementing building information modeling in Tanzania

The key objective of this thesis was to appraise the Building Information Modelling (BIM) in Tanzania. The thesis has shown that in Tanzania Building Information Modeling (BIM) can be used to improve Bills of Quantities (BOQ) productivity in the public construction project delivery. The thesis key contribution is the proposed fundamentals in developing a country specific BIM model. Equally, the study has given a more specific definition of Building Information Modeling (BIM) and shown the existing relationship of BIM and Bills of Quantities in improving performance construction projects delivery in Tanzania. This study, designed the hypothesis approach to describe the association between Building Information Modeling (BIM) and Bills of Quantities (BOQ), which facilitated the development of an economical and technologically simple BIM model parameters for Tanzania. Although the relationship found was insignificant, the developed 5DBIMBOQ model is expected to be more productive in the Total Cost Management (TCM) and hence improve information integration in the construction project deliveries in Tanzania. Further areas of study should include the empirical testing of hypothesis in order to further measure the behaviour of other key parameters like collaboration in order to develop the Tanzanian BIM Model

SBE16 Brazil & Portugal - Sustainable Urban Communities towards a Nearly Zero Impact Built Environment

Vol. IThe organizers of SBE 16 Brazil & Portugal were challenged to promote discussions and the development of solutions for an important and, at the same time, very ambitious topic ? Sustainable Urban Communities towards a Nearly Zero Impact Built Environment. This is the main focus of the international conference SBE16 Brazil & Portugal; the only event of the SBE16/17 conference series being held in Latin America, more precisely, in Vitória (Espírito Santo), Brazil, from the 7th until the 9th of September 2016. The conference offered a unique opportunity to bring together researchers from all over the world to share evidence-based knowledge in the field and succeeded to achieve its goals since many contributions from various parts of the planet were received, addressing a tiny part of the problem or trying to perform the difficult task of making the sum of the parts a coherent whole.info:eu-repo/semantics/publishedVersio

Taphonomy, environment or human plant exploitation strategies?: Deciphering changes in Pleistocene-Holocene plant representation at Umhlatuzana rockshelter, South Africa

The period between ~40 and 20 ka BP encompassing the Middle Stone Age (MSA) and Later Stone Age (LSA) transition has long been of interest because of the associated technological change. Understanding this transition in southern Africa is complicated by the paucity of archaeological sites that span this period. With its occupation sequence spanning the last ~70,000 years, Umhlatuzana Rock Shelter is one of the few sites that record this transition. Umhlatuzana thus offers a great opportunity to study past environmental dynamics from the Late Pleistocene (MIS 4) to the Late Holocene, and past human subsistence strategies, their social organisation, technological and symbolic innovations. Although organic preservation is poor (bones, seeds, and charcoal) at the site, silica phytoliths preserve generally well throughout the sequence. These microscopic silica particles can identify different plant types that are no longer visible at the site because of decomposition or burning to a reliable taxonomical level. Thus, to trace site occupation, plant resource use, and in turn reconstruct past vegetation, we applied phytolith analyses to sediment samples of the newly excavated Umhlatuzana sequence. We present results of the phytolith assemblage variability to determine change in plant use from the Pleistocene to the Holocene and discuss them in relation to taphonomical processes and human plant gathering strategies and activities. This study ultimately seeks to provide a palaeoenvironmental context for modes of occupation and will shed light on past human-environmental interactions in eastern South Africa.NWOVidi 276-60-004Human Origin

Ways and Capacity in Archaeological Data Management in Serbia

Over the past year and due to the COVID-19 pandemic, the entire world has witnessed inequalities across borders and societies. They also include access to archaeological resources, both physical and digital. Both archaeological data creators and users spent a lot of time working from their homes, away from artefact collections and research data. However, this was the perfect moment to understand the importance of making data freely and openly available, both nationally and internationally. This is why the authors of this paper chose to make a selection of data bases from various institutions responsible for preservation and protection of cultural heritage, in order to understand their policies regarding accessibility and usage of the data they keep. This will be done by simple visits to various web-sites or data bases. They intend to check on the volume and content, but also importance of the offered archaeological heritage. In addition, the authors will estimate whether the heritage has adequately been classified and described and also check whether data is available in foreign languages. It needs to be seen whether it is possible to access digital objects (documents and the accompanying metadata), whether access is opened for all users or it requires a certain hierarchy access, what is the policy of usage, reusage and distribution etc. It remains to be seen whether there are public API or whether it is possible to collect data through API. In case that there is a public API, one needs to check whether datasets are interoperable or messy, requiring data cleaning. After having visited a certain number of web-sites, the authors expect to collect enough data to make a satisfactory conclusion about accessibility and usage of Serbian archaeological data web bases

Neolithic land-use in the Dutch wetlands: estimating the land-use implications of resource exploitation strategies in the Middle Swifterbant Culture (4600-3900 BCE)

The Dutch wetlands witness the gradual adoption of Neolithic novelties by foraging societies during the Swifterbant period. Recent analyses provide new insights into the subsistence palette of Middle Swifterbant societies. Small-scale livestock herding and cultivation are in evidence at this time, but their importance if unclear. Within the framework of PAGES Land-use at 6000BP project, we aim to translate the information on resource exploitation into information on land-use that can be incorporated into global climate modelling efforts, with attention for the importance of agriculture. A reconstruction of patterns of resource exploitation and their land-use dimensions is complicated by methodological issues in comparing the results of varied recent investigations. Analyses of organic residues in ceramics have attested to the cooking of aquatic foods, ruminant meat, porcine meat, as well as rare cases of dairy. In terms of vegetative matter, some ceramics exclusively yielded evidence of wild plants, while others preserve cereal remains. Elevated δ15N values of human were interpreted as demonstrating an important aquatic component of the diet well into the 4th millennium BC. Yet recent assays on livestock remains suggest grazing on salt marshes partly accounts for the human values. Finally, renewed archaeozoological investigations have shown the early presence of domestic animals to be more limited than previously thought. We discuss the relative importance of exploited resources to produce a best-fit interpretation of changing patterns of land-use during the Middle Swifterbant phase. Our review combines recent archaeological data with wider data on anthropogenic influence on the landscape. Combining the results of plant macroremains, information from pollen cores about vegetation development, the structure of faunal assemblages, and finds of arable fields and dairy residue, we suggest the most parsimonious interpretation is one of a limited land-use footprint of cultivation and livestock keeping in Dutch wetlands between 4600 and 3900 BCE.NWOVidi 276-60-004Human Origin

Towards a standardised attack graph visual syntax

More research needs to focus on developing effective methods of aiding the understanding and perception of cyber-attacks. Attack modelling techniques (AMTs) - such as attack graphs, attack trees and fault trees, are popular methods of mathematically and visually representing the sequence of events that lead to a successful cyber-attack. Although useful in aiding cyber-attack perception, there is little empirical or comparative research which evaluates the effectiveness of these methods. Furthermore, there is no standardised attack graph visual syntax configuration, currently more than seventy-five self-nominated attack graph and twenty attack tree configurations have been described in the literature - each of which presents attributes such as preconditions and exploits in a different way. This research analyses methods of presenting cyber-attacks and reveals that attack graphs and attack trees are the dominant methods. The research proposes an attack graph visual syntax which is designed using evidence based principles. The proposed attack graph is compared with the fault tree - which is a standard method of representing events such as cyber-attacks. This comparison shows that the proposed attack graph visual syntax is more effective than the fault tree method at aiding cyber-attack perception and that the attack graph can be an effective tool for aiding cyber-attack perception - particularly in educational contexts. Although the proposed attack graph visual syntax is shown to be cognitively effective, this is no indication of practitioner acceptance. The research proceeds to identify a preferred attack graph visual syntax from a range of visual syntaxes - one of which is the proposed attack graph visual syntax. The method used to perform the comparison is conjoint analysis which is innovative for this field. The results of the second study reveal that the proposed attack graph visual syntax is one of the preferred configurations. This attack graph has the following attributes. The flow of events is represented top-down, preconditions are represented as rectangles, and exploits are represented as ellipses. The key contribution of this research is the development of an attack graph visual syntax which is effective in aiding the understanding of cyber-attacks particularly in educational contexts. The proposed method is a significant step towards standardising the attack graph visual syntax
