This paper analyses the media coverage of parental leave policies (parental and paternity leaves) in Swiss French-speaking press articles from 1999 to 2009. Switzerland is one of the rare European countries which has no statutory parental or paternity leave. The aim is to describe the mediatisation of these policies and to analyse the arguments in favour and against their implementation. We investigate the status of a fertility frame - the mobilisation of discourse relating to fertility issues - among the various arguments used to justify or reject parental leave policies. We proceed with a content analysis of 579 press articles, as well as a frame analysis on a subset in which parental leave policies are the central theme (N=206). Results show that paternity leave is the predominant public issue addressed in the dataset. A mediatisation peak was reached in 2007, following an initiative of a member of the Federal executive to implement a short paternity leave. Parental leave policies are predominantly represented in a positive light. The main positive frame is economic, in which leaves are represented as serving the interests of companies. Involved fatherhood and gender equality are also frequently mentioned as positive frames. The fertility frame is only moderately used in articles covering Swiss news on paternity leaves. Conversely, the fertility frame is largely mobilised in articles covering parental leave in other countries. We discuss some interpretations of this discrepancy and suggest future avenues of research on parental leave policies in Switzerland.

The most ordinary finite element formulations for 3D frame analysis do not consider the warping of cross-sections as part of their kinematics. So the stiffness, regarding torsion, should be directly introduced by the user into the computational software and the bar is treated as it is working under no warping hypothesis. This approach does not give good results for general structural elements applied in engineering. Both displacement and stress calculation reveal sensible deficiencies for both linear and non-linear applications. For linear analysis, displacements can be corrected by assuming a stiffness that results in acceptable global displacements of the analyzed structure. However, the stress calculation will be far from reality. For nonlinear analysis the deficiencies are even worse. In the past forty years, some special structural matrix analysis and finite element formulations have been proposed in literature to include warping and the bending-torsion effects for 3D general frame analysis considering both linear and non-linear situations. In this work, using a kinematics improvement technique, the degree of freedom ""warping intensity"" is introduced following a new approach for 3D frame elements. This degree of freedom is associated with the warping basic mode, a geometric characteristic of the cross-section, It does not have a direct relation with the rate of twist rotation along the longitudinal axis, as in existent formulations. Moreover, a linear strain variation mode is provided for the geometric non-linear approach, for which complete 3D constitutive relation (Saint-Venant Kirchhoff) is adopted. The proposed technique allows the consideration of inhomogeneous cross-sections with any geometry. Various examples are shown to demonstrate the accuracy and applicability of the proposed formulation. (C) 2009 Elsevier Inc. All rights reserved.

This paper presents an improved constitutive equation of frame in the context of continuous medium technique. This improved constitutive equation, which is a consistent formulation of column global bending, is applicable to a complete class of frameworks including the ideal shear frame panel, for which the beams are assumed to be rigid, and the associated column system, for which the rigidity of beams is negligible. Global buckling and second-order effects of the frame structure are discussed. The main results can be extended to other types of lateral stiffening elements as built-up columns. A worked example is presented in order to compare the main results with those obtained by the classic matrix method. Copyright (C) 2007 John Wiley & Sons, Ltd.

The purpose of this study was to determine how dental and medical school deans perceived their own leadership styles and how many management/leadership perspectives they used when approaching a problem. A descriptive and correlational study was conducted which examined the leadership orientations or "frames" utilized by these deans. Four frames--the structural, the human resource, the political, and the symbolic--emerged from leadership studies which described the behavior of leaders in organizational actions and problem solving.^ Employing the repeated measures ANCOVA, it was found that there were no significant interactions between type of dean and perceptions or perspectives. However, the main effects of both leadership style perceptions and the use of perspectives were significant. This indicated that over the total sample of deans, both perceptions and perspectives were used differently; the deans perceived themselves and used perspectives the highest for the human resource frame and the lowest for the political frame. Also, dental deans' mean use overall of the four perspective frames was higher than the medical deans. In addition to the ANCOVA, t-tests performed on perceptions revealed that the deans perceived the frames differently in three human resource items. Pearson's correlations indicated that for the combined sample of deans, significant negative correlations existed when the human resource or symbolic frame was compared to the structural frame. All of the deans used multiple frames, allowing them to re-frame or combine frames according to the situation. ^

This dissertation investigates the connection between spectral analysis and frame theory. When considering the spectral properties of a frame, we present a few novel results relating to the spectral decomposition. We first show that scalable frames have the property that the inner product of the scaling coefficients and the eigenvectors must equal the inverse eigenvalues. From this, we prove a similar result when an approximate scaling is obtained. We then focus on the optimization problems inherent to the scalable frames by first showing that there is an equivalence between scaling a frame and optimization problems with a non-restrictive objective function. Various objective functions are considered, and an analysis of the solution type is presented. For linear objectives, we can encourage sparse scalings, and with barrier objective functions, we force dense solutions. We further consider frames in high dimensions, and derive various solution techniques. From here, we restrict ourselves to various frame classes, to add more specificity to the results. Using frames generated from distributions allows for the placement of probabilistic bounds on scalability. For discrete distributions (Bernoulli and Rademacher), we bound the probability of encountering an ONB, and for continuous symmetric distributions (Uniform and Gaussian), we show that symmetry is retained in the transformed domain. We also prove several hyperplane-separation results. With the theory developed, we discuss graph applications of the scalability framework. We make a connection with graph conditioning, and show the in-feasibility of the problem in the general case. After a modification, we show that any complete graph can be conditioned. We then present a modification of standard PCA (robust PCA) developed by Cand\`es, and give some background into Electron Energy-Loss Spectroscopy (EELS). We design a novel scheme for the processing of EELS through robust PCA and least-squares regression, and test this scheme on biological samples. Finally, we take the idea of robust PCA and apply the technique of kernel PCA to perform robust manifold learning. We derive the problem and present an algorithm for its solution. There is also discussion of the differences with RPCA that make theoretical guarantees difficult.

This paper presents two case studies that suggest, in different but complementary ways, that the critical tool of frame analysis (Entman, 2002) has a place not only in the analytical environments of critical media research and media studies classes, where it is commonly found, but also in the media-production oriented environments of skills-based journalism training and even the newsroom. The expectations and constraints of both the latter environments, however, necessitate forms of frame analysis that are quick and simple. While commercial pressures mean newsrooms and skills-based journalism-training environments are likely to allow only an oversimplified approach to frame analysis, we argue that even a simple understanding and analysis at the production end could help to shift framing in ways that not only improve the quality and depth of Australasian newspapers' news coverage, but increase reader satisfaction with media output.

Alors que la mobilisation de la diaspora tamoule pendant la guerre civile sri lankaise (1983-2009) a été amplement discutée et analysée, peu de chercheurs se sont penchés sur la mobilisation de la diaspora tamoule après 2009. Pourtant, cette mobilisation d’après-guerre présente une rupture importante avec le discours d’indépendance du Liberation Tigers of Tamil Eelam (LTTE) prédominant pendant la guerre civile sri lankaise, rupture qui s’illustre, entre autres, par l’émergence d’un discours de reconnaissance du génocide. Comment expliquer ce changement de discours? L’objectif de ce mémoire est d’exposer le recadrage des actions collectives de la diaspora tamoule depuis 2009, pour ensuite expliquer comment et pourquoi nous l’observons. Pour ce faire, nous retraçons le discours de cinq acteurs collectifs en matière d’indépendance et de génocide, tel que rapporté par le site web diasporique, Tamilnet.com. Les acteurs collectifs à l’étude sont les suivants : le Liberation Tigers of Tamil Eelam (LTTE), le Global Tamil Forum (GTF), le Transnational Government of Tamil Eelam (TGTE), Tamils Against Genocide (TAG) et le National Council of Canadian Tamils (NCCT). Notre démarche, qui consiste en une analyse de cadrage, à la fois quantitative et qualitative, nous amène à remettre en question la relation causale entre la fenêtre d’opportunité et le recadrage. En revanche, nous démontrons que le recadrage des actions collectives de la diaspora tamoule depuis 2009 s’explique par l’émergence de nouveaux acteurs collectifs, eux-mêmes porteurs d’un nouveau discours. L’apparition de ces nouveaux acteurs collectifs médiate ainsi la relation entre la fenêtre d’opportunité et le recadrage.

At present, national-level policies concerning the eradication and control of bovine viral diarrhoea (BVD) differ widely across Europe. Some Scandinavian countries have enacted strong regulatory frameworks to eradicate the disease, whereas other countries have few formal policies. To examine these differences, the attitudes of stakeholders and policy makers in 17 European countries were investigated. A web-based questionnaire was sent to policy makers, government and private sector veterinarians, and representatives of farmers' organisations. On total, 131 individuals responded to the questionnaire and their responses were analysed by applying a method used in sociolinguistics: frame analysis. The results showed that the different attitudes of countries that applied compulsory or voluntary frameworks were associated with different views about the attribution or blame for BVD and the roles ascribed to farmers and other stakeholders in its eradication and control.

No contexto pós redemocratização, Estado e sociedade civil estão em transformação: discute-se novos modelos de gestão pública, mais descentralizados e gerenciais; enquanto proliferam as organizações sem fins lucrativos abrindo novos espaços também para a participação dos empresários nas decisões sobre os rumos do país. A accountability governamental entra na pauta e o controle social surge nas falas de movimentos sociais que chamam atenção pela diversidade de seus membros e pelas mudanças que vem provocando na institucionalidade vigente. Uma referencia destes movimentos é o Nossa São Paulo, articulador de mais de seiscentas organizações na segunda maior cidade do mundo e modelo organizacional e político para dezenas de iniciativas similares que se disseminam pelo país e pela America Latina. O objetivo desta pesquisa é compreender o lugar do controle social, e mais amplamente, da accountability governamental no processo de framing desenvolvido pelo Movimento Nossa São Paulo. Para tanto, realizou-se um estudo de caso exploratório, incluindo revisão da literatura, análise de documentos, observação em eventos e entrevistas em profundidade, focando nos momentos de gênese e mobilização do Movimento Nossa São Paulo e na articulação para a aprovação de legislação relacionada à accountability governamental. Este trabalho apresenta, assim, o percurso dos grupos que formam o Nossa São Paulo observando o surgimento do controle social como quadro interpretativo composto pela união entre movimentos historicamente vinculados pelo mote da justiça social e outros grupos ligados ao desenvolvimento urbano e à responsabilidade socioambiental, articulados no pleito pela sustentabilidade. Como pano de fundo, estão as discussões sobre o direito à cidade, os dilemas clássicos da representação e os novos caminhos no campo dos modelos democráticos.

A presente pesquisa objetiva analisar o uso que foi feito da violência, enquanto problema social, nos contextos jornalístico e político, a partir das matérias veiculadas no Jornal Nacional, da Rede Globo e nos discursos políticos dos candidatos à presidência da República, Geraldo Alckmin (PSDB) e Luiz Inácio Lula da Silva (PT), no horário eleitoral, denominado aqui de campanha eleitoral televisiva, das eleições de 2006. Como aportes metodológicos principais foram utilizadas as ferramentas de análise da hermenêutica e dos enquadramentos (frame analysis), com a intenção de desvelar esse olhar sobre a violência e fazer uma reflexão teórica sobre esse problema social no “pós-mídia”, termo designado nesta pesquisa para o processo de exacerbação da mídia e de sua inserção como instituição que constrói sentido da realidade para a vida das pessoas. O telejornal e a campanha eleitoral, analisados nos meses de agosto, setembro e outubro de 2006, foram tomados como importantes programas de referências na construção social da realidade. Constata-se que há uma superficialidade e homogeneização no tratamento desse problema social.
