Twitter has been a focus of research in political science for a few years now as it provides the opportunity to make direct observations on the spread of political information in different communities. Here we will be studying the phenomena of information diffusion, and focus on nodes that are responsible for spreading political information everywhere on the Twitter network. This paper attempts to fill gaps in the literature regarding the demographics of political retweeters using various techniques on the name and location-related data from most active French political retweeters. Here I will try to state the break-down of these accounts in categories based on gender, language, location, education level, and self-descriptions. To put the information about political retweeters in context we will also create a category of non-political retweeters to draw comparisons between the groups regarding the above-mentioned variables.

The Relationship

ABSTRACTRegret is a basic affect associated with individual choice. While much research in organizational science and consumer behavior has assessed the precedents and consequents of regret, little attention has been paid to regret in political science. The present study assesses the relationship between one of the most democratically consequential forms of political behavior—voting—and feelings of regret. We examine the extent to which citizens regret how they voted after doing so and the factors that might lead one individual to be more regretful than another. Relying on surveys in five different countries after 11 regional and national elections, we find not only that political information leads to a decrease in post-election regret, but also that having voted correctly, or having voted in accordance with one’s underlying preferences regardless of information, similarly mitigates regret. The effect of correct voting on regret is greater among the least informed.

Conjoint experiments have seen an explosion of interest within political science, enabling scholars to understand the preferences of citizens in a varietyof political contexts. However, one notable limitation of the standard conjointdesign is the textual medium; citizens frequently encounter political information encoded as images, and in particular, encounter implicit cues that cannotbe unawkwardly translated into the literal form of that standard conjoint. Wepresent a method for algorithmically generating images at scale, enabling us deploy conjoint experiments where subjects select between two images that encodethe denotational information possible in standard conjoints in addition to thesubtle image- or style-based information prominent in more ecologically validencounters with political information. We explore the utility of this methodin an application where subjects evaluate the Twitter profiles of hypotheticalcandidates. We demonstrate that the visual conjoint allows subjects to take inimage-based information and that it can also incorporate the social endorsementinformation that is central to politics on social media.

Abstract Religious leaders and congregants alike report high levels of political discussions in their churches. Yet, direct observations of political topics in a wide set of religious settings are rare. We examine the nature of political speech by clergy with a novel dataset of over 110,000 sermons. Using a computational text analysis approach and multiple forms of validation, we find political content in more than a third of religious sermons and that seven of 10 pastors discuss political topics at some point. Common topics include the economy, war, homosexuality, welfare, and abortion. We then use a geographic data to link the sermons to demographic and political information around the church and to information about the church and pastor to evaluate the variation of political content in sermons. We find that most pastors—across location and denomination—engage around political topics, confirming the intertwined nature of religion and politics in the United States.

Research within political science has found a relationship between experiencing state anxiety and an increase in information seeking. Specifically, when individuals feel anxious, they seek out threatening information relevant to the source of anxiety. But this research has generally treated exposure to anxiety-inducing information in the social environment as a given. This can be misleading because some people are more likely to experience political anxiety than others by virtue of their personal attributes. I assert that a person’s inherent anxiety level, independent of context (trait anxiety) will shape attention, processing information in one’s environment, to threatening information, which in turn makes that individual more or less likely to experience anxiety over politics. These differential experiences of political anxiety lead to variations in how people consume information. Utilizing a simulated information news board, I test this series of links and find that individual traits affect the propensity to experience political anxiety via attentional biases and this propensity influences the type of political information with which individuals engage. People high in trait anxiety show attentional biases towards anxiety-inducing content, the first study in political science to show trait anxious people show cognitive differences from people who are not trait anxious when it comes to politics. People high in trait anxiety also seek out a larger amount of threatening political information when experiencing anxiety over politics. Once individuals seek out a higher amount of threatening political information, they express more desire to engage in politics. This work highlights the importance of incorporating dispositional traits in research on emotions and politics.

Kinetics Of

The electron irradiation of silicate glasses containing metal cations produces various types of phase separation and decomposition which includes oxygen bubble formation at intermediate temperatures figure I. The kinetics of bubble formation are too rapid to be accounted for by oxygen diffusion but the behavior is consistent with a cation diffusion mechanism if the amount of oxygen in the bubble is not significantly different from that in the same volume of silicate glass. The formation of oxygen bubbles is often accompanied by precipitation of crystalline phases and/or amorphous phase decomposition in the regions between the bubbles and the detection of differences in oxygen concentration between the bubble and matrix by electron energy loss spectroscopy cannot be discerned (figure 2) even when the bubble occupies the majority of the foil depth.The oxygen bubbles are stable, even in the thin foils, months after irradiation and if van der Waals behavior of the interior gas is assumed an oxygen pressure of about 4000 atmospheres must be sustained for a 100 bubble if the surface tension with the glass matrix is to balance against it at intermediate temperatures.

Ledge Density

Ledges in grain boundaries can be identified by their characteristic contrast features (straight, black-white lines) distinct from those of lattice dislocations, for example1,2 [see Fig. 1(a) and (b)]. Simple contrast rules as pointed out by Murr and Venkatesh2, can be established so that ledges may be recognized with come confidence, and the number of ledges per unit length of grain boundary (referred to as the ledge density, m) measured by direct observations in the transmission electron microscope. Such measurements can then give rise to quantitative data which can be used to provide evidence for the influence of ledges on the physical and mechanical properties of materials.It has been shown that ledge density can be systematically altered in some metals by thermo-mechanical treatment3,4.

The growth of Ag films deposited on various substrate materials such as MoS2, mica, graphite, and MgO has been investigated extensively using the in situ electron microscopy technique. The three stages of film growth, namely, the nucleation, growth of islands followed by liquid-like coalescence have been observed in both the vacuum vapor deposited and ion beam sputtered thin films. The mechanisms of nucleation and growth of silver films formed by ion beam sputtering on the (111) plane of silicon comprise the subject of this paper. A novel mode of epitaxial growth is observed to that seen previously.The experimental arrangement for the present study is the same as previous experiments, and the preparation procedure for obtaining thin silicon substrate is presented in a separate paper.

Lattice Formation

The production of void lattices in metals as a result of displacement damage associated with high energy and heavy ion bombardment is now well documented. More recently, Murr has shown that a void lattice can be developed in natural (colored) fluorites observed in the transmission electron microscope. These were the first observations of a void lattice in an irradiated nonmetal, and the first, direct observations of color-center aggregates. Clinard, et al. have also recently observed a void lattice (described as a high density of aligned "pores") in neutron irradiated Al2O3 and Y2O3. In this latter work, itwas pointed out that in order that a cavity be formed,a near-stoichiometric ratio of cation and anion vacancies must aggregate. It was reasoned that two other alternatives to explain the pores were cation metal colloids and highpressure anion gas bubbles.Evans has proposed that void lattices result from the presence of a pre-existing impurity lattice, and predicted that the formation of a void lattice should restrict swelling in irradiated materials because it represents a state of saturation.

One aspect of enzyme cytochemistry is, whether all macrophage lysosomal hydrolytical enzymes are present in an active form, or are activated upon stimulation. Integrated morphometrical and chemical analysis has been chosen as a tool to illucidate that cytochemical problem. Mouse peritoneal resident macrophages have been used as a model for this complicated integration of morphometrical and element-related data. Only aldehyde-fixed cells were treated with three cytochemical reactions to detect different enzyme activities within one cell (for details see [1,2]). The enzyme-related precipitates anticipated to be differentiated, were:(1).lysosomal barium and sulphur from aryl sulphatase activity,(2).lysosomal cerium and phosphate from acid phosphatase activity and(3).platinum/di-amino-benzidine( D A B) complex from endogenous peroxidase activity.
