On the Heisenberg condition in the presence of redundant poles of the S-matrix

For the same potential as originally studied by Ma [Phys. Rev. {\bf 71}, 195 (1947)] we obtain analytic expressions for the Jost functions and the residui of the S-matrix of both (i) redundant poles and (ii) the poles corresponding to true bound states. This enables us to demonstrate that the Heisenberg condition is valid in spite of the presence of redundant poles and singular behaviour of the S-matrix for $k\to \infty$. In addition, we analytically determine the overall contribution of redundant poles to the asymptotic completeness relation, provided that the residuum theorem can be applied. The origin of redundant poles and zeros is shown to be related to peculiarities of analytic continuation of a parameter of two linearly independent analytic functions.Comment: The Heisenberg condition has been reduced down to analytic relation (35) for the cylindrical Bessel functions (7 pages, 1 figure

Discrimination is in the Eye of the Beholder: Perception of Discrimination and Microaggressions

The present work sought to examine the perception of discrimination toward sexual and romantic minorities. In particular, microaggressions (subtle messages of hostility based on group membership) were examined as a potential factor in varying reports of discrimination frequency. Findings showed that both minority and majority group members agreed that the minority group experienced more discrimination in their day-to-day lives than did the majority group; the minority and majority groups also showed agreement regarding the frequency of this day-to-day discrimination. An indirect model of influence was found, in which frequency ratings of discrimination toward the minority group were impacted by frequency ratings of discrimination toward the self; frequency ratings of discrimination toward the self were predicted by sensitivity toward microaggressions, which in turn was predicted by minority vs. majority group status. These findings represent a first step in understanding the role of perception of microaggressions in the identification of discrimination

Modern Homonegativity and LGBTQ Activism: The Role of Identity and Behaviour in Attitude Formation

Although reported prejudice toward sexual minorities seems to be decreasing over time, sexual minorities themselves continue to report many experiences of prejudice and discrimination. One potential explanation for this discrepancy in the sexual prejudice literature is that explicit prejudice is being measured in a manner that is no longer culturally relevant, as proposed by Morrison and Morrison (2003) in the development of their Modern Homonegativity Scale. Modern homonegativity (MH) is characterized by negative attitudes toward behaviours and policies that benefit LGBTQ people, rather than a negative attitude toward homosexuality itself. The present work aimed to further the field’s understanding of MH and the role it plays in the formation of attitudes toward others. In Study 1, participants read one of three character profiles, each describing a gay man who volunteered with a particular group: an LGBTQ activism group, an environmental activism group, or a local library. Participants rated the target higher on negative trait descriptors when he was an LGBTQ activist. Study 2, a replication and extension of this work that included straight and female targets, showed a more complicated interaction of participant gender, target gender, target orientation, and target activism. A brief third study assessed which trait descriptors were most commonly applied to volunteers in order to ensure the validity of the outcome variables. Study 4 extended Studies 1 and 2 with the inclusion of MH as a predictor and with a behavioural measure added to the survey. The data from Study 4 suggested that MH contributes to the formation of negative attitudes across conditions, but that it also interacts with both activism condition and orientation to create negative attitudes. This supports the idea that although MH does interact with behavioural information to produce negative attitudes, it also interacts with orientation to produce less favourable attitudes toward gay targets even when activism is held constant. Implications for further work on MH and sexual prejudice in general are discussed

Vitamin D as One of Predicators of the Stable Viral Response to Antiviral Therapy in Patients with Chronis Hepatitis С

Chronic hepatitis C (CHC) it is not exceptionally medical problem but a significant social and economic threat, taking into account the unfavorable consequences of this disease: cirrhosis and hepatocellular carcinoma. And as a result - the high level of disability. In the article are presented the results of examination of 41 patients with chronic hepatitis C, with 1 genotype, who received the antiviral therapy (AVT). All patients underwent determination of the level of 5-hydroxycholeсalсeferol (25-OH vit D3), vitamin D and also the study of IL-28B polymorphism as the one of predicators of response to AVT. It was demonstrated, that in patients with hepatitis was observed the deficit of 25-OH vit D3 and general vitamin D. It was established, that in patients with the normal 25-OH vit D3 level SVR (stable viral response) was observed in 1,4 times more often than in patients with deficit of 25-OH vit D3. That is the level of 25-OH vit D3 can be considered as a predicator of SVR to AVT
