Confusion surrounds the nature of the “adenomatoid tumor” of the testis, as evidenced by the large number of synonyms which have been ascribed to it. Various authors have considered the tumor to be of endothelial, mesothelial or epithelial origin. There appears to be no controversy as to the stromal elements of the tumor, which consists mainly of smooth muscle and fibrous tissue. It is the irregular gland-like spaces which have given rise to the numerous theories as to its histogenesis, and even recent ultrastructural studies fail to agree on the origin of these structures.Electron microscopy of a typical intrascrotal adenomatoid tumor showed the gland-like spaces to be lined by epithelial cells (Fig. 1), rich in cytoplasmic tonofibrils and united to each other by numerous desmosomes (Fig. 2). The most salient feature of these epithelial cells was the presence on their luminal surface of numerous long and repeatedly branching microvillous structures of the type known as stereocilia (Fig. 3). These are extremely long slender cell processes which are as much as three to four times the length of those in brush borders.

Unusual Shape

Several TEM investigations have attempted to correlate the structural characteristics to the unusual shape memory effect in NiTi, the consensus being the essence of the memory effect is ostensible manifest in the structure of NiTi transforming martensitic- ally from a B2 ordered lattice to a low temperature monoclinic phase. Commensurate with the low symmetry of the martensite phase, many variants may form from the B2 lattice explaining the very complex transformed microstructure. The microstructure may also be complicated by the enhanced formation of oxide or hydride phases and precipitation of intermetallic compounds by electron beam exposure. Variants are typically found in selfaccommodation groups with members of a group internally twinned and the twins themselves are often observed to be internally twinned. Often the most salient feature of a group of variants is their close clustering around a given orientation. Analysis of such orientation relationships may be a key to determining the nature of the reaction path that gives the transformation its apparently perfect reversibility.

Present Information

If the resolving power of a scanning electron microscope can be improved until it is comparable to that of a conventional microscope, it would serve as a valuable additional tool in many investigations.The salient feature of scanning microscopes is that the image-forming process takes place before the electrons strike the specimen. This means that several different detection systems can be employed in order to present information about the specimen. In our own particular work we have concentrated on the use of energy loss information in the beam which is transmitted through the specimen, but there are also numerous other possibilities (such as secondary emission, generation of X-rays, and cathode luminescence).Another difference between the pictures one would obtain from the scanning microscope and those obtained from a conventional microscope is that the diffraction phenomena are totally different. The only diffraction phenomena which would be seen in the scanning microscope are those which exist in the beam itself, and not those produced by the specimen.

This article examines the current globalization of political antisemitism and its effects on the resurgent normalization of anti-Jewish discourse and politics in a global context. The focus is on three political spaces in which the “Jewish question” has been repoliticized and become a salient feature of political ideology, communication, and mobilization: the global radical right, global Islamism, and the global radical left. Different contexts and justificatory discourses notwithstanding, the comparative empirical analysis shows that three interrelated elements of globalized antisemitism feature most prominently across these different political spaces: anti-Jewish conspiracy myths; Holocaust denial or relativization; and hatred of Israel. It is argued that the current process of the globalization of political antisemitism has significantly contributed to antisemitism’s presence in all kinds of public spaces as well as the convergence of antisemitic ideology among a variety of different actors. Moreover, the globalization of political antisemitism has helped accelerate the dissemination and social acceptance of anti-Jewish tropes that currently take shape in broader publics, that is: the globalized mainstreaming of antisemitism. The article concludes by discussing some factors favorable to the globalization and normalization of antisemitism, and the resurgence of antisemitic politics in the current age.

AbstractFollowing Blommaert (2005), this paper examines what he calls a ‘forgotten’ context within Critical Discourse Analysis (CDA) and Conversation Analysis (CA) – that of text trajectories. For Blommaert, a limitation of both CDA and CA is their focus on “the unique, one-time” instance of a given text and, by extension, the (limited) context associated with such an instance of text. Such a focus, according to Blommaert, ignores a salient feature of communication in contemporary societies – the fact that texts and discourses move around, are repeatedly recontextualized in new interpretive spaces, and in the process undergo significant transformations in meaning. The text trajectory investigated in this paper begins in a legal institution, more specifically, with a 2004 American rape trial, Maouloud Baby v. the State of Maryland. This legal case garnered much media attention and, as a result of such exposure, references to the case have appeared in both mainstream and social media outlets. Hence, as a ‘text’ that has displayed considerable movement across different contexts within the legal system and, subsequently, beyond the legal system to mainstream and popular forms of media, the Maouloud Baby trial constitutes fertile ground for the exploration of a text's trajectory. Indeed, in keeping with Blommaert's claims, I show how this trial's ‘text’ undergoes significant transformations in meaning as it is recontextualized in different kinds of interpretive spaces (both within the legal system and outside of it) and how these transformations in meaning reproduce larger patterns of gendered inequalities.

Hypothetical Scenario

Abstract Regulators require lenders to display a subset of credit card features in summary tables before customers finalize a credit card choice. Some jurisdictions require some features to be displayed more prominently than others to help ensure that consumers are made aware of them. This approach could lead to untoward effects on choice, such that relevant but nonprominent product features do not factor in as significantly. To test this possibility, we instructed a random sample of 1615 adults to choose between two hypothetical credit cards whose features were shown side by side in tables. The sample was instructed to select the card that would result in the lowest financial charges, given a hypothetical scenario. Critically, we randomly varied whether the annual interest rates and fees were made visually salient by making one, both, or neither brighter than other features. The findings show that even among credit-savvy individuals, choice tends strongly toward the product that outperforms the other on a salient feature. As a result, we encourage regulators to consider not only whether a key feature should be made more salient, but also the guidelines regarding when a key feature should be displayed prominently during credit card acquisition.

Pancreatic Necrosis Virus

ABSTRACT Infectious pancreatic necrosis virus (IPNV), a pathogen of salmon and trout, imposes a severe toll on the aquaculture and sea farming industries. IPNV belongs to the Aquabirnavirus genus in the Birnaviridae family of bisegmented double-stranded RNA viruses. The virions are nonenveloped with a T=13l icosahedral capsid made by the coat protein VP2, the three-dimensional (3D) organization of which is known in detail for the family prototype, the infectious bursal disease virus (IBDV) of poultry. A salient feature of the birnavirus architecture is the presence of 260 trimeric spikes formed by VP2, projecting radially from the capsid. The spikes carry the principal antigenic sites as well as virulence and cell adaptation determinants. We report here the 3.4-Å resolution crystal structure of a subviral particle (SVP) of IPNV, containing 20 VP2 trimers organized with icosahedral symmetry. We show that, as expected, the SVPs have a very similar organization to the IBDV counterparts, with VP2 exhibiting the same overall 3D fold. However, the spikes are significantly different, displaying a more compact organization with tighter packing about the molecular 3-fold axis. Amino acids controlling virulence and cell culture adaptation cluster differently at the top of the spike, i.e., in a central bowl in IBDV and at the periphery in IPNV. In contrast, the spike base features an exposed groove, conserved across birnavirus genera, which contains an integrin-binding motif. Thus, in addition to revealing the viral antigenic determinants, the structure suggests that birnaviruses interact with different receptors for attachment and for cell internalization during entry.

Psychological Features

In recent years, an upsurge of polarization has been a salient feature of political discourse in America. A small but growing body of research has examined the potential relevance of intellectual humility (IH) to political polarization. In the present investigation, we extend this work to political myside bias, testing the hypothesis that IH is associated with less bias in two community samples (N1 = 498; N2 = 477). In line with our expectations, measures of IH were negatively correlated with political myside bias across paradigms, political topics, and samples. These relations were robust to controlling for humility. We also examined ideological asymmetries in the relations between IH and political myside bias, finding that IH-bias relations were statistically equivalent in members of the political left and right. Notwithstanding important limitations and caveats, these data establish IH as one of a small handful psychological features known to predict less political myside bias.
