The Stability

In this paper, I discuss the theory behind the use of a dense, concentrated neutron particle-based beam. I look at the particle based physics behind such a beam, when it is focused against solid material matter. Although this idea is still only theoretical, it appears that such a beam may be capable of disrupting the stability of the atoms within solid matter- in some cases by passing great volumes of neutrons between the electron and nucleus thus effectively “shielding” the electron from the charge of the nucleus. In other cases, by disrupting the nucleus by firing neutrons into it, disrupting the nucleus and weakening its bond on electrons. In either case- the resulting effect would be a disruption of the atom, which in the case of material matter would cause said material matter to fail, which would appear to the observer as liquification with some plasma generation. Thus, a dense neutron particle based beam could be used to effectively liquefy material matter. Such a beam could bore through rock, metal, or even thick, military grade armour, like that used on tanks- causing such materials to rapidly liquefy. The denser and thicker the neutron beam, the more devastating the effect of the beam- thus the faster material matter will liquefy and the greater the area of liquification. Such a beam would have applications in Defence, mining and drilling operations.

Prevention Theory

There are claims that the societal appetite for ‘child exploitation material’ is increasing. Yet, Australia’s policy response does not include initiatives to dissuade potential offenders from deliberately viewing child exploitation material for the first time (onset). To critically examine this issue, this paper draws on Situational Crime Prevention theory. It argues that (a) many first-time child exploitation material viewers fit the Situational Crime Prevention construct of the Opportunistic Offender and (b) suggests that current policy overlooks the kinds of non-instrumental factors that increase the risk of onset for this group, including doubts about the criminality and harmfulness of viewing child exploitation material. The paper then empirically examines social attitudes to child exploitation material viewing by presenting the findings of a survey of 504 Australian internet users. Results indicate that a sizeable minority of the participants were: unaware that it is a crime to view certain types of child exploitation material in Australia; and held doubts about the harmfulness of viewing child exploitation material. These findings are used to reflect on how the presence of these non-instrumental factors among ordinary internet users may affect the offending readiness of the Opportunistic Offender. Policy implications are then briefly discussed.

Essential Questions

This book about the materiality of interaction is not only concerned with how materials and how the notion of materiality is related to interaction design, but as we shift perspectives from representations to materials we also need to look closely at this central notion of interaction and we need to discuss what it is, and if a shift of perspectives here also has implications for how this term should and can be used in the context of interaction design – and when designing for interaction. And even more fundamentally, the title of this book is ‘the materiality of interaction’ and not ‘the materiality of a computer’ so at this point it is probably a good idea to reflect upon what we mean when we say that we do interaction design, how we define this term interaction, and how we see interaction as being at least partly a material matter. This chapter is devoted to these essential questions.

Reflexive Analysis

Ethnographic research is a thoroughly material matter, but the involvement of material things in performing ethnographic methods is hardly investigated. Referring to my own research in various fields of digitalized work, I offer a reflexive analysis of the material production of ethnographic presence. In particular, I reflect on how clothing, field notes, and a camera contribute to making ethnographic research noticeable for and accessible to participants. Taking a practice theory perspective, the article conceptualizes ethnographic presence as a situated performance based on the dramaturgical and embodying contributions of material things. My analysis challenges the idea of openness as an ideal of research ethics that could be realized independently of the material and situated circumstances of fieldwork. It also shows that the material making of ethnographic presence offers particular methodological benefits including epistemic partnerships, insights from staged behavior, and the facilitation of ethnographic data collection.

El presente trabajo analiza la decisión de la Cour constitutionnelle belga 18/2016, de 3 de febrero, mediante la cual se examina la constitucionalidad del artículo 318 en sus apartados primero y segundo del Código civil belga, a raíz de la presentación de dos cuestiones prejudiciales por el tribunal de primera instancia francófono de Bruselas. El estudio de esta decisión sobre la constitucionalidad la actuación del legislador en el ámbito de los procesos de filiación, evidencia la relevancia constitucional de una causa que sitúa en el centro de la reflexión jurídica los derechos a la vida privada y familiar y al desarrollo del niño y la garantía del carácter preferente del interés del hijo en todo aquello que le concierna, y por su conexión, también el derecho de igualdad y no discriminación entre los hijos. El juicio de constitucionalidad será construido sobre la jurisprudencia del TEDH relativa al contenido y alcance de los derechos a la vida privada y familiar. Junto a ello, y al margen de la repercusión mediática y social del asunto material, la singularidad del sujeto frente que dirigen las acciones filiación que origina el pronunciamiento constitucional, proyectan este análisis jurídico sobre el estatuto jurídico del monarca y sobre las consecuencias de la abdicación como titular de la Jefatura del Estado.This paper analyzes the decision by the Belgian Cour constitutionnelle n.º 18/2016, 3 February. In this decision, the Court examines the constitutionality of 318 paragraphs first and second, of the Belgian Civil Code, due to the presentation of two referred questions by the Court of First Instance francophone in Brussels. The analysis of this decision in the context of the processes of filiation, lies at the heart of the legal reflection the rights to private and family life, the development of children and the guarantee the preferential nature of the interest of the child in all that it is concerned, and by their connection also the right to equality and non-discrimination among children. The constitutional judgment will be constructed over the jurisprudence of the ECHR regarding the content and scope of rights to private and family life. Moreover and regardless from the media and social impact of the material matter, the facts that substantiate the cause of filiation project this legal analysis on the status of the monarch as head of the Head of State and on the consequences of the abdication in the crown.
