Alcohol use, alcohol-related aggression and intimate partner abuse: a cross-sectional survey of convicted versus general population men in Scotland

Introduction and Aims. Scotland has a particular problem with alcohol, and the links between intimate partner abuse (IPA) and alcohol appear stronger here than elsewhere across Europe. This study explored differences in alcohol use, related aggression and relationship conflict across a number of groups: men convicted for intimate partner abuse, men convicted of general offences and men recruited from community sports teams. Design and Methods. Participants (n = 64) completed three questionnaires exploring their experiences of alcohol use (Alcohol Use Disorders Identification Test, AUDIT); alcohol and aggression (Alcohol Related Aggression Questionnaire, ARAQ-28), and relationship conflict (Revised Conflict Tactics Scale, CTS-2). Results. There were significant differences across the groups in terms of AUDIT and ARAQ-28 scores, IPA and general offenders scored higher than the community sample. CTS-2 scores showed significant differences: both offender groups reported more use of negotiation and psychological abuse, than the community men, and IPA offenders reported causing more physical harm than either general offenders or the community sample. ARAQ-28 scores correlated with psychological abuse for general offenders. Alcohol use was very high across all groups, but the community group did not endorse an aggression-precipitating view of alcohol and did not report high IPA. Discussion and Conclusions. Discussed is the need for cross-cultural research to explore putative mediators and moderators in the relationship between alcohol, aggressiveness and IPA.

An Artificial Life Approach to Configuring Architectural Space

This paper presents a method of configuring architectural space that articulates the coupling of an organism with its environment; expressing the spatiality of unfolding engagement in the world. The premise is that space is a consequence of cohesion, effected through constraints and processes of enaction. An Artificial Life model is presented as an analogue of a bottom-up approach to architectural design that takes into account that we as organisms interact with our ever present changing environment and redefine our spatial domain depending on our sensory interaction with said environment

Empirische Shortcuts:Studentische Forschungsprojekte in der Methodenlehre

Die empirische Bildungsforschung hat in den letzten Jahren einen nachhaltigen quantitativen und qualitativen Aufschwung genommen. Erziehungswissenschaftliche Forschung erschöpft sich jedoch nicht im M&E des schulischen Lernstands im nationalen und internationalen Vergleich und seiner Ursachen sondern umfasst ein weites Feld an Fragestellungen aus unterschiedlichsten Bereichen. Dies muss den Studierenden, neben den methodischen Modellen und Instrumentarien exemplarisch vermittelt werden. Das ideale didaktische Modell hierfür ist zweifellos ein von den Studierenden selbst konzipiertes und durchgeführtes Forschungsprojekt, wie es seit Jahren im Programmbereich „Empirische Pädagogik“ des Instituts für Erziehungswissenschaft der WWU Münster praktiziert. Dadurch werden den Studierenden Dimensionen eröffnet, die im Zeitalter von Modularisierung, OECD-Statistiken und Ressourcenverknappung sich zunehmend verengen. Die damit verbundenen Impulse und Erfahrungsgewinne sind in eine Belebung und Bereicherung des Studiums

Actuating (Auto)Poiesis

This paper claims that the use of the computer as generative methodological tool for designing urban and building scenarios (when perceived systematically) is a misnomer, because the typical approach does not account for the incompleteness of computational processes. We will argue that the computerisation of architectural and urban scenarios with autopoietic and/or artificial life simulations does not account for what Edsger W. Dijkstra called “radical novelty”; and Gilles Deleuze termed “line of flight”. Typical computational methods do not open up genuine alternatives that produce radical morphologies. Our argument is predicated on the dominant notion of computation as opposed to a critique of computation per se. A critical analysis of the perception of novelty is made to support our view, and its connection with the incompleteness of axiomatic systems is explored in relation to three phases of cybernetic enquiry. Our argument draws on the ontologies of Alfred North Whitehead and Gilles Deleuze, which we utilise to reorient computational design to emphasise the potential of generating radical novelty and identify the inherent locus therein a matter of nonhuman decision-making

Resolving the gap and AU-scale asymmetries in the pre-transitional disk of V1247 Orionis

Pre-transitional disks are protoplanetary disks with a gapped disk structure, potentially indicating the presence of young planets in these systems. In order to explore the structure of these objects and their gap-opening mechanism, we observed the pre-transitional disk V1247 Orionis using the Very Large Telescope Interferometer, the Keck Interferometer, Keck-II, Gemini South, and IRTF. This allows us spatially resolve the AU-scale disk structure from near- to mid-infrared wavelengths (1.5 to 13 {\mu}m), tracing material at different temperatures and over a wide range of stellocentric radii. Our observations reveal a narrow, optically-thick inner-disk component (located at 0.18 AU from the star) that is separated from the optically thick outer disk (radii >46 AU), providing unambiguous evidence for the existence of a gap in this pre-transitional disk. Surprisingly, we find that the gap region is filled with significant amounts of optically thin material with a carbon-dominated dust mineralogy. The presence of this optically thin gap material cannot be deduced solely from the spectral energy distribution, yet it is the dominant contributor at mid-infrared wavelengths. Furthermore, using Keck/NIRC2 aperture masking observations in the H, K', and L' band, we detect asymmetries in the brightness distribution on scales of about 15-40 AU, i.e. within the gap region. The detected asymmetries are highly significant, yet their amplitude and direction changes with wavelength, which is not consistent with a companion interpretation but indicates an inhomogeneous distribution of the gap material. We interpret this as strong evidence for the presence of complex density structures, possibly reflecting the dynamical interaction of the disk material with sub-stellar mass bodies that are responsible for the gap clearing.Comment: 16 pages, 17 Figures, accepted by Astrophysical Journa

The Science Case for the Planet Formation Imager (PFI)

Among the most fascinating and hotly-debated areas in contemporary astrophysics are the means by which planetary systems are assembled from the large rotating disks of gas and dust which attend a stellar birth. Although important work has already been, and is still being done both in theory and observation, a full understanding of the physics of planet formation can only be achieved by opening observational windows able to directly witness the process in action. The key requirement is then to probe planet-forming systems at the natural spatial scales over which material is being assembled. By definition, this is the so-called Hill Sphere which delineates the region of influence of a gravitating body within its surrounding environment. The Planet Formation Imager project (PFI) has crystallized around this challenging goal: to deliver resolved images of Hill-Sphere-sized structures within candidate planet-hosting disks in the nearest star-forming regions. In this contribution we outline the primary science case of PFI. For this purpose, we briefly review our knowledge about the planet-formation process and discuss recent observational results that have been obtained on the class of transition disks. Spectro-photometric and multi-wavelength interferometric studies of these systems revealed the presence of extended gaps and complex density inhomogeneities that might be triggered by orbiting planets. We present detailed 3-D radiation-hydrodynamic simulations of disks with single and multiple embedded planets, from which we compute synthetic images at near-infrared, mid-infrared, far-infrared, and sub-millimeter wavelengths, enabling a direct comparison of the signatures that are detectable with PFI and complementary facilities such as ALMA. From these simulations, we derive some preliminary specifications that will guide the array design and technology roadmap of the facility.Comment: SPIE Astronomical Telescopes and Instrumentation conference, June 2014, Paper ID 9146-120, 13 pages, 3 Figure

The Fundamental Problem of the Science of Information

The concept of information has been extensively studied and written about, yet no consensus on a unified definition of information has to date been reached. This paper seeks to establish the basis for a unified definition of information. We claim a biosemiotics perspective, based on Gregory Bateson’s definition of information, provides a footing on which to build because the frame this provides has applicability to both the sciences and humanities. A key issue in reaching a unified definition of information is the fundamental problem of identify ing how a human o rgan ism, in a self-referential process, develops from a state in which its knowledge of the h uman-organism-in-its-environment is almost non-existent to a state in which the human organism not only recognizes the existence of the environment but also sees itself as part of the human-organism-in-its-environment system. This allows a human organism not only to self-referentially engage with the environment and navigate through it, but also to transform it i n its own image and likeness. In other words, the Fundamental Problem of the Science of Information concerns the phylogenetic development process, as well as the ontogenetic development process of Homo sapiens sapiens from a single cell to our current multicellular selves, all in a changing long-term and short-term environment, respectively
