Bifurcation and symmetry breaking for the Henon equation
No full textIn this paper, we consider the henon problem
in the unit ball of R^N, N≥3, with Dirchlet boundery conditions. We prove the existence of (at least) one branch of non-radial solutions that bifurcate from the radial ones and that this branch is unbounded
With Friends Like These: Foreign Policy as Personal Relationship
No full textGovernments are run by humans who have sympathies and moods. The study of leaders’ personalities, albeit not widespread, is an important tool for foreign policy analysis. Plus, friendship is a feeling that decision-makers like to express for each other. This paper analyses the activity of Silvio Berlusconi, Italy’s three times premier, who has made ‘friendship’ a central tenet of his personal foreign policy. Three cases are considered, namely, Berlusconi’s relationship with George W. Bush, Tony Blair and Vladimir Putin.
The paper concludes that his friendship-based foreign policy has somehow worked; but, because he decided to ignore Italy’s structural constraints in the international arena, he ended up wasting opportunities and resources
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Predicting the vote: Implicit attitudes as predictors of the future behavior of decided and undecided voters
Full text linkTwo studies assessed the predictive validity of implicit political attitudes in relation to voting behavior. In Study 1, we demonstrated the validity of the adopted measure (i.e., the
IAT; Greenwald, McGhee, & Schwartz, 1998) with a sample of voters who clearly sided with one of the opposing parties. In Study 2, implicit political preferences were measured in
a sample of undecided voters one month before the election, and actual voting behavior was assessed immediately after the election. Results demonstrated that implicit political attitudes
were good predictors of future voting behaviors. These findings support the hypothesis of the presence of embryonic attitudes even in the case of those voters who at the explicit and conscious level deny any preference for one of the two opposing candidates
