The God of classical Christian faith is radically transcendent--utterly beyond understanding and words. So if God is to be known it must be in the luminous darkness of unknowing. Drawing on a wide range of primary sources--biblical, patristic, and medieval--Barry D. Smith identifies and explores seven ways of expressing the otherness of God in classical Christian thinking. By allowing historical theologians to speak for themselves, he shows how an aversion to ontotheology long precedes postmodernism. The book first lays out (...) the Old Testament and New Testament foundations for subsequent Christian reflections on divine transcendence. These were the teachings that the early church assumed and, with the assistance of Greek philosophy, further refined with their own set of apophatic conceptual tools. The main focus of the book is a sevenfold exposition of that theological refinement. Smith concludes by looking towards possible future theological developments within this apophatic tradition. Drawing on the theological methodology of historic Christianity, he indicates how a synthesis of the biblical teaching on the otherness of God with philosophical traditions other than those inherited from Greek philosophy is also possible.

Embryogenesis requires the precise movement and reorganization of many cell and tissue types. Presumably, cell surface receptors allow cells to interact selectively with adjacent cells and with the extracellular environment, as well as initiate differentiative events by transducing appropriate signals across the plasma membrane. One cell surface component that serves as a receptor during a variety of cellular interactions is β1,4‐galactosyltransferase. Cell surface galactosyltransferase participates in diverse cellular interactions by binding its specific glycoconjugate substrate on adjacent cell surfaces or in (...) the extracellular matrix. Biochemical, immunological, and molecular probes are being used to better define cell surface galactosyl‐transferase functional in cellular interactions during fertilization, intercellular adhesion, cell migration, and growth control.

The chief sources of groundwater contamination on farms come from point sources and diffuse sources. Possible point sources are feedlots, poorly-sited manure piles, septic sewage-treatment systems—all of which can release nitrate, phosphates and bacteria— and sites of chemical spills. Diffuse sources are typified by excess fertilizer leaching from a number of arable fields. The basis of quality standards for drinking-water is discussed in relation to common contaminants present on farms. Samples of drinking-water were collected in 1991–1992 from wells on about (...) 1,200 farms in order to study the quality of rural groundwater in Ontario. Analysis showed that approximately one third of wells were contaminated with bacteria, 14% were contaminated with nitrate, two wells were contaminated with pesticide, but 40% were considered unsafe because of the presence of at least one contaminant. These values were similar to those reported for similar regions in the U.S. There was no significant effect of agricultural practice on the proportion of contaminated samples. One response of Ontario's farmers to information on water quality has been to initiate their own program, the Environmental Farm Plan, which has 23 modules by which the risk of environmental contamination can be assessed. Government policies for agriculture can be expected to influence farming practices. However, the literature suggests that the consequences of policies aimed at reducing environmental contamination are poorly understood, not least because the instruments used for implementation can have widely differing impacts. The need for discussions on the ethics surrounding the relationship between food producers and consumers with regard to environmental contamination is identified. (shrink)

Abstractβ1,4‐galactosyltransferase is unusual among the glycosyltransferases in that it is found in two subcellular compartments where it performs two distinct functions. In the trans‐Golgi complex, galactosyltransferase participates in oligosaccharide biosynthesis, as do the other glycosyltransferases. On the cell surface, however, galactosyltransferase associates with the cytoskeleton and functions as a receptor for extracellular oligosaccharide ligands. Although we now know much regarding galactosyltransferase function in these two compartments, little is known about how it is targeted to these different sites. By cloning the (...) galactosyltransferase gene products, certain features of the protein have been identified that may be critical for its expression on the cell surface or retention within the Golgi complex. This article discusses recent studies which suggest that a cytoplasmic sequence unique to one galactosyltransferase isoform is required for targeting a portion of this protein to the plasma membrane, enabling it to function as a cell adhesion molecule. These findings allow one to manipulate surface galactosyltransferase expression, either positively or negatively, and perturb galactosyltransferase‐dependent cellular interactions during fertilization and development.

This research illustrates dangers inherent in the gap created when organizations decouple ethics program adoption from implementation. Using a sample of 182 professionals in the pharmaceutical and financial services industries, we examine the relationship between structural decoupling of formal ethics programs and individual-level perceptions and behavior. Findings strongly support the hypothesized relationships between decoupling and organizational members’ legitimacy perceptions of the ethics program, psychological contract breach, organizational cynicism, and unethical behavior.

In the era of “big data,” science is increasingly information driven, and the potential for computers to store, manage, and integrate massive amounts of data has given rise to such new disciplinary fields as biomedical informatics. Applied ontology offers a strategy for the organization of scientific information in computer-tractable form, drawing on concepts not only from computer and information science but also from linguistics, logic, and philosophy. This book provides an introduction to the field of applied ontology that is of (...) particular relevance to biomedicine, covering theoretical components of ontologies, best practices for ontology design, and examples of biomedical ontologies in use. After defining an ontology as a representation of the types of entities in a given domain, the book distinguishes between different kinds of ontologies and taxonomies, and shows how applied ontology draws on more traditional ideas from metaphysics. It presents the core features of the Basic Formal Ontology (BFO), now used by over one hundred ontology projects around the world, and offers examples of domain ontologies that utilize BFO. The book also describes Web Ontology Language (OWL), a common framework for Semantic Web technologies. Throughout, the book provides concrete recommendations for the design and construction of domain ontologies. (shrink)

The question of what the relevant entities or units of analysis for studying the dynamics of R&D are is central not only for adequate characterizations of the system of scientific and technological knowledge production but also for determining the correct focus for evaluation of R&D activities. Typically, R&D performance evaluations have focused not only on the wrong thing but have looked in the wrong place. Most evaluations have been project or program based. Often this focus is misleading. This article presents (...) a “knowledge value” framework as an alternative focus for understanding and evaluating scientific and technical work. This framework consists of two core concepts: the Knowledge Value Collective and the Knowledge Value Alliance. On the basis of the analysis of twenty-eight case studies of research activities, the authors present a typology of KVAs and conclude that they are a better object of evaluation than discipline-based projects.

In the past the law relating to involuntary manslaughter has been the subject of much criticism and controversy, though surprisingly it has received comparatively little attention during the recent review of the homicide law by the Law Commission and the Ministry of Justice. As far as the authors are aware, there has hitherto been no objective empirical research into cases of involuntary manslaughter in England and Wales. Based on data collected from case files maintained by HM Court Service and the (...) Crown Prosecution Service, this article provides a brief analysis of a sample of 127 recent cases. As well as the usual criminological analysis (of offender and offence characteristics), the article focuses on the variations in offenders’ moral culpability for causing death; the relationship between murder and manslaughter (especially those manslaughters at the ‘upper end’ of the seriousness scale); the categorization of different species of involuntary manslaughter, and the sentencing of convicted manslayers.

Despite the challenges associated with virtually mediated communication, remote collaboration is a defining characteristic of online multiplayer gaming communities. Inspired by the teamwork exhibited by players in first-person shooter games, this study investigated the verbal and behavioral coordination of four-player teams playing a cooperative online video game. The game, Desert Herding, involved teams consisting of three ground players and one drone operator tasked to locate, corral, and contain evasive robot agents scattered across a large desert environment. Ground players could move (...) throughout the environment, while the drone operator’s role was akin to that of a “spectator” with a bird’s-eye view, with access to veridical information of the locations of teammates and the to-be-corralled agents. Categorical recurrence quantification analysis was used to measure the communication dynamics of teams as they completed the task. Demands on coordination were manipulated by varying the ground players’ ability to observe the environment with the use of game “fog.” Results show that catRQA was sensitive to changes to task visibility, with reductions in task visibility reorganizing how participants conversed during the game to maintain team situation awareness. The results are discussed in the context of future work that can address how team coordination can be augmented with the inclusion of artificial agents, as synthetic teammates. (shrink)

This article draws on the sociology of expectations to examine the construction of expectations of ‘ethical AI’ and considers the implications of these expectations for communication governance. We first analyse a range of public documents to identify the key actors, mechanisms and issues which structure societal expectations around artificial intelligence and an emerging discourse on ethics. We then explore expectations of AI and ethics through a survey of members of the public. Finally, we discuss the implications of our findings for (...) the role of AI in communication governance. We find that, despite societal expectations that we can design ethical AI, and public expectations that developers and governments should share responsibility for the outcomes of AI use, there is a significant divergence between these expectations and the ways in which AI technologies are currently used and governed in large scale communication systems. We conclude that discourses of ‘ethical AI’ are generically performative, but to become more effective we need to acknowledge the limitations of contemporary AI and the requirement for extensive human labour to meet the challenges of communication governance. An effective ethics of AI requires domain appropriate AI tools, updated professional practices, dignified places of work and robust regulatory and accountability frameworks. (shrink)

Several themes can be identified in the commentaries. The first is that the climbing fibers may have more than one function; the second is that the climbing fibers provide sensory rather than motor signals. We accept the possibility that climbing fibers may have more than one function consequence(s)’ in the title. Until we know more about the function of the inhibitory input to the inferior olive from the cerebellar nuclei, which are motor structures, we have to keep open the possibility (...) that the climbing fiber signals can be a combination of sensory and motor signals.
