Is the polarity of content producers strongly influenced by the results of the event?

This paper presents an approach to compare two types of data, subjective data (Polarity of Pan American Games 2011 event by country) and objective data (the number of medals won by each participating country), based on the Pearson corre- lation. When dealing with events described by people, knowledge acquisition is difficult because their structure is heterogeneous and subjective. A first step towards knowing the polarity of the information provided by people consists in automatically classifying the posts into clusters according to their polarity. The authors carried out a set of experiments using a corpus that consists of 5600 posts extracted from 168 Internet resources related to a specific event: the 2011 Pan American games. The approach is based on four components: a crawler, a filter, a synthesizer and a polarity analyzer. The PanAmerican approach automatically classifies the polarity of the event into clusters with the following results: 588 positive, 336 neutral, and 76 negative. Our work found out that the polarity of the content produced was strongly influenced by the results of the event with a correlation of .74. Thus, it is possible to conclude that the polarity of content is strongly affected by the results of the event. Finally, the accuracy of the PanAmerican approach is: .87, .90, and .80 according to the precision of the three classes of polarity evaluated.

Effect of content characteristics on quality of experience of adaptive streaming

The growing popularity of adaptive streaming-based video delivery nowadays has raised the interest about the user's perception when experiencing quality adaptation. The impact of the video content characteristics on user's perceptual quality has already become evident. The aim of this study is to investigate the influence of this factor on the quality of experience of adaptive streaming scenarios. Our results show that the perceptual quality of adaptation strategies applied on videos with high spatial and low temporal amount of activity is significantly lower compared to the other content types.

The dimensions of the protein import channels in the outer and inner mitochondrial membranes

Most mitochondrial proteins are imported into mitochondria through transmembrane channels composed largely, and perhaps exclusively, of proteins. We have determined the effective internal diameter of the protein import channel in the mitochondrial outer membrane to be between 20 Å and 26 Å during translocation. The diameter of the import channel in the inner membrane is smaller than the diameter of the outer membrane import channel. These results were obtained by measuring the effect of rigid steric bulk introduced into precursor proteins on import.

The Affective Dimensions of Social Controversy

Social controversy is a sustained, mediated debate between at least two oppositional parties which is more than just a difference of opinion; rather it is a persistent conflict over the political and cultural implications that dominant forms of communicative reasoning, practices, and norms have for a public. Simply put, during social controversies the norms guiding public life can be negotiated, reaffirmed, negated, and/or transformed. This can lead to progressive political, cultural, and/or social change in some instances, while establishing or reifying conservative and even oppressive norms, practices, and laws in others. Building upon Olson and Goodnight's (1994) theoretical and methodological framework of social controversy, this dissertation argues that scholars should analyze the role affect plays in this type of conflict as a means to address the regulation of public conduct as well as public discourse. The rhetorical and argumentative significance of the affective dimensions of social controversy have been conceptualized and analyzed via an examination of emotion-based claims and affective states that have become salient, discernable and/or apprehendable during specific public disagreements. Such a conceptualization demonstrates that critical insights regarding the norms that guide public conduct, the role risk and vulnerability play in the regulation of individuals' public behavior, and the relationship between affect and citizenship can be gained by focusing on a controversy's affective dimensions. To highlight the importance of the study of affect in social controversy as well as better understand the larger critical significance affect theory has for rhetorical and argumentation studies, this dissertation has analyzed the affective dimensions of three conflicts. They are: the Abu Ghraib prisoner abuse social controversy, the International Freedom Center social controversy, and the controversy over the 2004 French ban on conspicuous religious attire in public schools. The findings from this dissertation that have specific and general implications for future work in the field of controversy as well as rhetoric and argumentation, respectively.

On the existence of fractal strings whose set of dimensions of fractality is not perfect

In this paper we give an example of a nonlattice self-similar fractal string such that the set of real parts of their complex dimensions has an isolated point. This proves that, in general, the set of dimensions of fractality of a fractal string is not a perfect set.

On the Complex Dimensions of Nonlattice Fractal Strings in Connection with Dirichlet Polynomials

In this paper we give a new characterization of the closure of the set of the real parts of the zeros of a particular class of Dirichlet polynomials that is associated with the set of dimensions of fractality of certain fractal strings. We show, for some representative cases of nonlattice Dirichlet polynomials, that the real parts of their zeros are dense in their associated critical intervals, confirming the conjecture and the numerical experiments made by M. Lapidus and M. van Frankenhuysen in several papers.

Cyclical dimensions of labour mobility after EU enlargement. Bruegel Working Paper 2009/03, May 2009

At a time of symmetric global slowdown, migration cannot contribute as much to absorbing economic shocks as it could if the shock were asymmetric. • Early evidence suggests that the crisis has led to a drop in immigration and even net return migration from some countries. This has helped the adjustment of former EU15 host countries and has exacerbated adjustment in former source countries in the new member states. In the short run, the stock of new member-state migrants in the EU15 will fall owing to diminished job opportunities for migrants. • Changes in the unemployment rate in the host country are found to impact migration more than that of changes in the unemployment rate in the source country. In part, this can be explained by the disproportionate risk of migrants losing their jobs in the downturn. • In the longer run, the crisis is set to increase migration from the new member states compared to what would have been the case without the crisis. This is because the crisis has undermined the economic growth model of those new member states that relied heavily on external financing to fuel their growth.

Bundeswehr 3.0: The political, military and social dimensions of the reform of the German armed forces. OSW Point of View Number 28, May 2012

This reform of the Bundeswehr, launched in 2011, is the latest of the three decisive stages in the post-war transformation of the German armed forces. The reform aims at “constructing” the armed forces anew in the political, military and social dimensions.The present paper presents the evolution of the role of the armed forces in German foreign and security policy and the ongoing process of “constructing” a new Bundeswehr. It analyses the process of redefining the objectives and principles of: the Bundeswehr’s participation in international operations, its current military transformation, and changes in its image and social identity. It also presents the implications of this broader transformation for political and military.
