Construction procurement systems : a linkage with project organisational models

This paper constitutes a literature review undertaken at the start of a two and a half year EPSRC funded research project. As such, its purpose is to present the details of the ‘re-search’concerning construction procurement and project organizational design. The paper shows that the ‘post -Latham’construction industry provides several new developments (client power, partnering, concurrent engineering etc) which are altering the construction project process, and therefore prove worthy vehicles for investigation into project organizational structures

Project communication variables : a comparative study of US and UK industry perceptions

Research undertaken at the Construction Industry Institute (CII) in the USA has indicated the need for project managers to focus their attention on six ‘Critical Communication Variables’ as a means of ensuring the fulfillment of time cost and quality targets. These variables refer to the accuracy, timeliness and completeness of information presented to participants, as well as the level of understanding, barriers to and procedures for project based communication. The findings and tools generated by the CII study have been used as part of case study based research examining construction projects in the Central Belt region of Scotland. In addition to the CII data collection tools employed, the Scottish study included semi-structured interviews as a means of contextualising the communication and decision-making taking place. This paper presents the results of this benchmarking exercise, and highlights significant issues that project team members need to improve upon in order to achieve the timeliness quality and cost required in today’s construction industr

The potential of agroforestry for utilisation as a significant development force in rural Kwazulu/Natal : the case of Kwabiyela

Bibliography: leaves 219-230.Agroforestry (the incorporation of woody perennials into crop production and animal husbandry systems) is placed within the rural development context at the local and national scales, and its potential role in attaining sustainable rural development evaluated. It is suggested as an appropriate response to social economic and ecological problems in the study area (located in KwaBiyela, a northern part of the former 'homeland' of KwaZulu), with potential applications for South Africa in general. A diagnostic survey of 90 households applying a questionnaire of open-ended design, and conducted within the Diagnosis and Design framework of the International Council for Research in Agroforestry, has established that problems exist in all farm production subsystems (cash, savings/investment, food production, energy, shelter, and raw materials) in the study area. The findings include an overwhelmingly positive response towards agroforestry. Recommendations for agroforestry implementation are formulated based on the results of the diagnostic survey, taking into consideration information relating to the functioning of the local society and economy. Importantly, these recommendations consist of agroforestry components which are flexible, can be combined in a number of ways as extensions of current farming practices, and pay particular attention to the utilisation of locally available resource, familiar to the people of the study area, to solve local problems. In this way, the adaptability and survivability of recommended practices is enhanced. In conclusion the requirements for the development of agroforestry in South Africa are discussed in the light of the structural transition currently under way in the country

Artificial Intelligence and Theological Personhood

Can AI be a person? What does God tell us about humanity and personhood? These are questions of theological anthropology and involve inquiring after the nature of humanity as God’s creation and what God wills for human personhood. To address these inquiries, we will look at three biblical texts that bear on issues of theological anthropology, hopefully garnering some theological resources to consider the anthropological status of AI. Specifically, we will look at three “creation” texts that necessarily deal with the nature of human personhood within the divine economy of salvation history. The first is Genesis 1 and 2, which recount the origin of humanity within God’s creative action. The second is the Prologue of the Gospel of John, which speaks of the incarnation as the will of God in the world, revealing and reconciling the nature of personhood. The third is Pentecost, which speaks of the divine reign of God in the redemption of humanity and the rest of creation. In each section, I will look at the text with an eye toward drawing out theological themes that will help in our inquiry concerning both the nature of personhood and the nature of AI

A Theological Framework for Reflection on Artificial Intelligence

The theological questions before us in a digital age are pressing. What does God think of AI? Is AI good or evil? Will AI save us? What sort of future will AI give us? In what follows, I want to briefly introduce a few theological concepts that will hopefully help equip us for theological reflection on AI. We will begin with the question of epistemology, or how it is that we come by knowledge; in the realm of theology, this centers on revelation. We will then touch on the doctrine of creation, including the understanding of what it means to be a human creature. Next, we will review aspects of the doctrine of salvation. Finally, we will discuss eschatology, the study of “last things.” I will close by posing some thoughts on what and how theology fits within our evolving digital wisdom

AI, Faith, and the Future

Artificial intelligence is rapidly and radically changing our lives and world. This book is a multidisciplinary engagement with the present and future impacts of AI from the standpoint of Christian faith. It provides technological, philosophical, and theological foundations for thinking about AI, as well as a series of reflections on the impact of AI on relationships, behavior, education, work, and moral action. The book serves as an accessible introduction to AI as well as a guide to wise consideration, design, and use of AI by examining foundational understandings and beliefs from a Christian perspective.https://digitalcommons.spu.edu/open_books/1002/thumbnail.jp

Distance measures to compare real and ideal quantum processes

With growing success in experimental implementations it is critical to identify a "gold standard" for quantum information processing, a single measure of distance that can be used to compare and contrast different experiments. We enumerate a set of criteria such a distance measure must satisfy to be both experimentally and theoretically meaningful. We then assess a wide range of possible measures against these criteria, before making a recommendation as to the best measures to use in characterizing quantum information processing.Comment: 15 pages; this version in line with published versio

Estimating the spatial distribution of crime events around a football stadium from georeferenced tweets

Crowd-based events, such as football matches, are considered generators of crime. Criminological research on the influence of football matches has consistently uncovered differences in spatial crime patterns, particularly in the areas around stadia. At the same time, social media data mining research on football matches shows a high volume of data created during football events. This study seeks to build on these two research streams by exploring the spatial relationship between crime events and nearby Twitter activity around a football stadium, and estimating the possible influence of tweets for explaining the presence or absence of crime in the area around a football stadium on match days. Aggregated hourly crime data and geotagged tweets for the same area around the stadium are analysed using exploratory and inferential methods. Spatial clustering, spatial statistics, text mining as well as a hurdle negative binomial logistic regression for spatiotemporal explanations are utilized in our analysis. Findings indicate a statistically significant spatial relationship between three crime types (criminal damage, theft and handling, and violence against the person) and tweet patterns, and that such a relationship can be used to explain future incidents of crime

Basin-Fill Stratigraphy, Quaternary History, and Paleomagnetics of the Eagle Flat Study Area, Southern Hudspeth County, Texas

Data and analyses of basin-fill stratigraphy, paleomagnetics, Quaternary history, and pseudo-fissures/fissures were acquired and interpreted by the Bureau of Economic Geology (BEG) in the Eagle Flat study area in southern Hudspeth County, Texas. These investigations were funded by the Texas Low-Level Radioactive Waste Disposal Authority (the Authority) as part of the evaluation of a proposed site for the Texas low-level radioactive waste repository. Data and information developed as a result of these investigations will be used to evaluate the proposed waste repository site and surrounding region and to provide data for performance assessment, design, and licensing activities. Basin-fill sediments are composed predominantly of sandy mud and mud; sands are abundant at the surface in the vicinity of the proposed repository site, and gravels are abundant at the base of the basin fill adjacent to the bedrock. Basin-fill thickness ranges from 163 ft (50 m) on the southeast side of the proposed site to 715 ft (218 m) on the northeast side of the proposed site. Basin-fill thickness is approximately 200 ft (61 m) on the west side of the proposed site. Coarser basin-fill deposits are interpreted as proximal alluvial fans and colluvium, and finer sands and muds are interpreted as ephemeral stream, distal alluvial fan, alluvial flat, and eolian deposits. At the proposed site, near-surface fine gravel and coarse to fine sand deposits exhibit characteristics consistent with fluvial deposition. Some well-sorted fine-grained sands have textures consistent with eolian sediments. Fine-grained sands and muds are interpreted as distal alluvial fan and ephemeral stream deposits.Bureau of Economic Geolog
