Abstract In 1921, the experimental physicist Rudolf Ladenburg put forward the first quantum interpretation of optical dispersion. Theoretical physicists had tried to explain dispersion from the point of view of quantum theory ever since 1913, when Niels Bohr proposed his quantum model of atom. Yet, their theories proved unsuccessful. It was Ladenburg who gave a breakthrough step toward our quantum understanding of dispersion. In order to understand Ladenburg’s step, I analyze Ladenburg’s experimental work on dispersion prior to 1913, the reasons why the first theories of dispersion after 1913 were not satisfactory, and Ladenburg’s 1921 proposal. I argue that Ladenburg’s early experimental work on dispersion is indispensable to understand his 1921 paper. The specific kind of experiments he performed before 1913, the related interpretative problems, and the way he tried to solve them, led him reapproach the dispersion problem in 1921 in a way that was completely different from the way theoretical physicists had done it before.

ResumenEl trabajo analiza el curso Ética Profesional en la carrera de Derecho en la Universidad Católica de Temuco. Examina la forma como se abordaba la ética profesional antes de la creación del curso, y lo que ha ocurrido con él a través de sucesivos cambios curriculares y la introducción del modelo por competencias. El curso aporta al sello identitario, mediante un enfoque multidisciplinario. El curso ha vinculado teoría y práctica, desde que comenzó a implementarse, hasta llegar actualmente a comprenderlo en la lógica de competencias. Esta mirada implica formar a los estudiantes para resolver dilemas éticos, lo que se hace mediante la metodología del ver–juzgar–actuar. Esta metodología de discernimiento es propia de la tradicióncatólica, pero se usa en este contexto sin un cariz religioso. El método en cuestión permite ir educando la autonomía a fn de tomar decisiones. Se analiza la importancia de contextualizar la enseñanza ética y la forma como esto se ha hecho en el curso. Finalmente se aborda la relevancia de formar la conciencia ética de los estudiantes.Palabras clave: Experiencia de enseñanza – Ética profesional –Método de discernimient.ResumoO artigo analisa o curso de Ética Profssional na Escola de Direito na Universidade Católica de Temuco.

It reviews the way in which ethics was addressed before the course was created, and what has happened with it through the subsequent curricular changes and the implementation of a competency based model. The course contributes to the seal of identity through a multidisciplinary approach. Theory and practice have been progressively bound together since the course was introduced, to reach a point, nowadays, in which the course is understood within the logic of competencies. This point of view implies educating students for solving ethical dilemmas, which is done through the see–judge–act methodology. This discernment methodology belongs to the Roman Catholic tradition, but is used in this context without its religious complexion. This method allows educating autonomy in order to make decisions. It also analyses the importance of contextualizing ethics education and the way in which this has been done in the course. Finally, it addresses the relevance ofcreating an ethical consciousness of the students.Keywords: Teaching experience – Professional Ethics – Discernment method

In order to provide information on the way in which use of drugs - and of alcohol and tobacco -among young people changes over a period of time, the Norwegian National Institute for Alcohol Research has each spring, since 1968, conducted a survey of the youth of Oslo to determine their use of these drugs. The results are of significance not only from a scientific point of view but also from the point of view of practical policy-making. For instance, since 1974 there does not seem to have been any increase in alcohol consumption among the youth of Oslo, a fact which may reflect the measures which were introduced at that time in order to curb alcohol consumption among young people in Norway.

This overview draws out the main conclusions from the 4 workshops focused on incorporating the patient perspective into outcome assessment at the 10th Outcome Measures in Rheumatology (OMERACT 10) conference. They raised methodological issues about the choice of outcome domains to include in clinical trials, the development or choice of instruments to measure these domains, and the way these instruments might capture the impact of a disease and its treatment. The need to develop a more rigorous conceptual model of quantifying the way conditions affect health, and the need to ensure patients are directly involved in the decisions about domains and instruments, emerged clearly. The OMERACT participants voted to develop guidelines for domain and instrument selection, and conceptual and experimental work will be brought forward to revise and upgrade the OMERACT Filter.

What is remix today? No longer a controversy, no longer a buzzword, remix is both everywhere and nowhere in contemporary media. This article examines this situation, looking at what remix now means when it is, for the most part, just an accepted part of the media landscape. I argue that remix should be looked at from an ethnographic point of view, focused on how and why remixes are used. To that end, this article identifies three ways of conceptualizing remix, based on intention rather than content: the aesthetic, communicative, and conceptual forms. It explores the history of (talking about) remix, looking at the tension between seeing remix as a form of art and remix as a mode of ‘talking back’ to the media, and how those tensions can be resolved in looking at the different ways remix originated. Finally, it addresses what ubiquitous remix might mean for the way we think about archival material, and the challenges this brings for archives themselves. In this way, this article updates the study of remix for a time when remix is everywhere.

Evolutionary Point

It is well known that in many orders of typically winged insects species occur which in the adult stage are apterous or have the wings so reduced in size that flight is impossible. Sometimes the reduction of wings affects one sex only, as in the case of the females of certain moths, but in the majority of cases it is exhibited by both sexes. In many instances wing dimorphism occurs irrespective of sex, one form of the species having fully developed wings and the other greatly reduced wings. In some species the wings are polymorphic. The problem of the origin of reduced wings and of other functionless organs is one of great interest from the evolutionary point of view. Various theories have been advanced in explanation, but in the majority of cases the various aspects of the subject are too little known to warrant discussion. More experimental work is required to show how far environmental conditions on the one hand, and hereditary factors on the other, are responsible for this phenomenon. Those species which exhibit alary dimorphism afford material for the study of the inheritance of the two types of wings, but only in a few cases has this method of research been utilized.

This article examines the use of a presumption of illegality by local police officers to enforce a deportation regime in the Northwest Arkansas region. We employed an integrated racialized legal violence model to understand the way officers and immigration authorities collaborate to screen immigrants’ legal status for deportation purposes. Rather than focusing on how collaborations operate from an institutional point of view, the article provided a detailed and rich experiential description of participants’ realities shaped by the interplay of migration policy and local police practices. We concluded that the screening tactics used by local police in the cases considered in this article reflect a form of racialized legal violence intended to enforce a deportation regime against unauthorized people of Latino origin from this Arkansas area.

From a perceptual point of view it is not clear whether, and under what conditions, the presence of colour in television commercials aids the processing of information. In this study it was argued that the way in which colour is used, would have an effect on the comprehension and memory of children regarding television commercials. It was found that colour, when used in a "concrete" fashion, aids the comprehension process. The results of the study also show that the "concrete" as well as the "symbolic" use of colour have a positive effect on the memory of children for the content of television commercials. Opsomming Vanuit 'n perseptuele benadering is dit nie duidelik of, en onder watter omstandighede, die teenwoordigheid van kleur in televisie advertensies die prosessering van inligting positief bei'nvloed nie. In hierdie studie is daar van die standpunt uitgegaan dat die wyse van kleurgebruik 'n effek sal he op die begrip en geheue van kinders ten aansien van televisie advertensies. Daar is gevind dat kleur, wat op 'n "konkrete" manier gebruik word, die begripsproses bevorder. Die resultate van die studie toon ook dat sowel die "konkrete" as "simboliese" gebruik van kleur 'n positiewe effek op die geheue van kinders ten opsigte van televisie advertensie inhoud het.

IN CAMERA LUCIDA, ROLAND BARTHES'S subject is the significance of photography's defining characteristic: the photograph's inseparable relation to its subject, that which ''must have been'' in front of the camera's lens. Or so it would seem. The present reading of Camera Lucida argues that Barthes's essay actually shows photography's nature as dependent not only on the intimate relation to its object, commonly termed ''indexical,'' but in accord with its relation to its user, its beholder. An examination of Barthes's encounters with photographs in Camera Lucida reveals the way in which identification and misidentification figure into the viewing of images, and suggests that contact between the beholder and the photograph actually eclipses the relation between the photograph and its subject. Barthes's focus on the emotional response of the viewer disguises the fact that he misidentified key details in Camera Lucida's photographs, most significantly in a 1927 portrait by James Van Der Zee and in the ''Winter Garden Photograph.'' This latter photograph of Barthes's recently deceased mother as a small child is famously not illustrated in the book. This essay argues that it is fictional. These ''mistakes'' suggest that Camera Lucida undermines its ostensible basis in indexicality. The subject did not have to be in front of the camera after all. The present rereading of the text from this point of view articulates a notion of performativity according to which the nature of the contact that exists between the image and the viewer informs the way an image is understood. Barthes's desire to find his mother again through her photograph to a large extent acts out his desire to re(per)form and make permanent his relation to her, a desire that he elucidates in the process of describing his search for her picture and his reaction to it when he finds it. This performative element is charged with identification; the person the narrator (Barthes) seeks, in his mother, is himself. A close analysis of the ''Winter Garden Photograph,'' as described by Barthes, shows how performances of identification are inscribed with gender and familial configurations.

AbstractModern poetry developed and transformed difficulty into a prominent aesthetic norm of poetry. The abundance of difficult poetic texts necessitates a study of the corpus. After differentiating between the way difficulty is perceived in poetry and in other communicative acts, I present the approach that I have adopted for the purpose of studying difficult poetry. In contrast to other studies which have examined difficulty from the author's perspective and, as a consequence, described factors that cause textual difficulty, I propose to examine the subject from the reader's point of view. The reader, after all, is the one who feels or does not feel the difficulty. The concept ‘difficult poem’ is necessarily interdisciplinary and the question of what is “difficult” involves cognitive psychology and its models of text comprehension. Following a discussion of these domains, I present the “definition” that I propose for the ‘difficult poem’.

Objetiva-se discutir neste breve intróito retrospectivo de revisão de normatizações constitucionais pátrias a tutela do animal doméstico. Esta síntese reflexiva sobre a tutela do animal doméstico brasileiro no âmbito constitucional se apresenta quanto à forma de abordagem do assunto, como qualitativo, no que tange a modalidade investigativa como básico, do ponto de vista de seus objetivos, como descritivo, com relação aos procedimentos técnicos, qualifica-se como documental e bibliográfico. Conclui-se que os delineamentos, os limites, bem como os avanços na conquista da tutela animal e consequentemente do animal doméstico demonstram o quanto o reconhecimento de tal questão é socialmente construído. Além disso, a expansão, a solidificação e o desenvolvimento contínuo também da vida humana e da sociedade implicam necessariamente na preservação e na ampliação de acesso um direito fundamental nominalmente reconhecido pela Constituição Federal de 1988 como direito ao ambiente ecologicamente equilibrado no qual se insere evidentemente a fauna, ou seja, os animais domésticos, domesticados, silvestres e exóticos. Palavras-chave: Animal Doméstico. Tutela. Constituições Federais. Brasil.  AbstractThe objective of this brief retrospective introjective review of constitutional norms is to discuss the protection of domestic animals. This reflexive synthesis about the protection of the Brazilian domestic animal in the constitutional scope presents itself as to the way of approaching the subject, as qualitative, in what refers to the research modality as basic, from the point of view of its objectives, as descriptive, with respect to the procedures technicians, qualifies as documentary and bibliographical. It is concluded that the delineations, the limits, as well as the advances in the conquest of the animal guardianship and consequently of the domestic animal demonstrate how much the recognition of such question is socially constructed. In addition, the expansion, solidification and continuous development of human life and society necessarily imply the preservation and expansion of access to a fundamental right nominally recognized by the Federal Constitution of 1988 as a right to an environmentally balanced environment in which the animal, domesticated, wild and exotic animals. Keywords: Domestic Animals.
