Quark Mass Effects in Fermionic Decays of the Higgs Boson in O(αs2)O(\alpha_s^2) Perturbative QCD

The results of analytical evaluation of $O(\alpha_s^2)$ QCD contributions due to the nonvanishing quark masses to $\Gamma_{H\rightarrow q_f\overline{q}_f}$ are presented. The ``triangle anomaly'' type contributions are included. As a byproduct the $O(\alpha_s^3)$ logarithmic contributions are evaluated. The results are presented both in terms of running and pole quark masses. The partial decay modes $H \rightarrow b\overline{b}$ and $H \rightarrow c\overline{c}$ are considered. The calculated corrections decrease the absolute value of large and negative $O(\alpha_s^2)$ massless limit coefficient by $\leq 1\%$ in the intermediate mass region and by 1\%$-$20\% in the low mass region which, however, is experimentally ruled out. The results are relevant for $H \rightarrow t\overline{t}$ decay mode for the higher Higgs mass region where the mass effects are large and important. The high order corrections remove a very large discrepancy between the results for $\Gamma_{H\rightarrow q_f\overline{q}_f}$ in terms of running and pole quark masses almost completely and reduce the scale dependence from about 40\% to nearly 5\%.Comment: 16 pages, LATeX, +5 figures available upon request, preprint OITS-543 (University of Oregon, USA, May 1994). ( Additions are made: Previous general result for the H-->qq is applied to the H-->tt decay mode where the calculated corrections are significant.

ON THE EVALUATIVE CONNOTATIONS OF PHRASEOLOGICAL ZOONYMS IN A CONTRASTIVE PERSPECTIVE (BASED ON FRENCH AND GEORGIAN PHRASEOLOGICAL UNITS)

The article is devoted to the study of French and Georgian phraseological units with animal names/zoonyms that represent emotional attitude of the speaker towards a person or a phenomenon. We decided to study this problem on the basis of phraseological units as phraseology is the sphere which reveals each culture’s ethnic and psychological peculiarities, their customs and traditions, reflects their world vision.The analysis revealed that each culture shows its attitude towards this or that phenomenon emotionally through phraseological units with zoonyms. Such kind of phraseological units intensify emotions and beautify the speech of the speakers. Besides behind each phraseological unit with zoonyms one can see customs, traditions, temperament of different cultures. In order to find similarities or differences between phraseological units of two unrelated languages, we have collected phraseological units with zoonyms and classified them into several groups. Using observational, descriptive, psycholinguistic and contrastive methods, we have found out seven types of zoonyms with evaluative connotations in French and nine types of zoonyms with evaluative connotations in Georgian. It seems that representatives of both cultures use phraseological units with zoonyms to show their emotions. The analysis also revealed that evaluative phraseological units with zoonyms mostly carry negative connotation in both languages

The Role of Social Support and Demographic Characteristics in Academic and Clinical Burnout of Mental Health Professionals in Training

Although there is an abundance of literature on clinician burnout within the mental health field, there is a gap in research about student burnout, especially for the student population undergoing clinical training. The aim of this research was to fill the gap in literature on burnout and explore factors that might contribute to or buffer burnout among student clinicians. This research particularly focused on the differences in burnout rates between students\u27 academic life and their clinical practice. Using the theory of conservation of resources, it was hypothesized that social support would serve as a buffer for burnout of student clinicians. Additionally, this research studied the relationship between burnout level and demographic characteristics such as age, gender, marital status, race/ethnicity of student clinicians. Furthermore, the relationship between burnout and level of perceived competency was explored. Finally, the impact of combination of responsibilities on both academic and clinical burnout was studied. The analyses yielded several significant findings regarding clinical and academic burnout. Firstly, students experienced academic burnout, which was demonstrated by high levels of cynicism and exhaustion and moderate levels of personal efficacy. Students’ clinical burnout was demonstrated by moderate levels of emotional exhaustion and personal accomplishment and by low level of depersonalization. These results indicate that burnout of student clinicians is real and deserves attention. When comparing clinical burnout of our sample with published data, our participants experienced higher levels of emotional exhaustion and personal accomplishment and lower levels of depersonalization than norms of mental health providers (Maslach, Jackson, & Leiter, 1996). Clinical and academic burnout had a significantly different distribution of scores for all subscales, suggesting that student clinicians experience significantly different levels of burnout in their academic and clinical lives. Levels of academic burnout were higher compared with clinical burnout. Demographic characteristics were not correlated with level of burnout in this study. Neither clinical nor academic burnout were significantly correlated with the degree of autonomy, nor with the level of functioning of clients. Feelings of competency were not related to clinical or academic burnout, with the exception of clinical personal accomplishment. Both clinical and academic burnout were affected by students’ combined responsibilities across most subscales. The participants’ ratings of social support were significantly negatively associated with feelings of academic and clinical burnout, as indicated by the Emotional Exhaustion, Depersonalization, and Cynicism subscales. Ratings of social support were significantly positively related to self-reported measures of Personal Accomplishment and Personal Efficacy. The only burnout subscale not significantly associated with social support was Academic Exhaustion. Taken together, these findings suggest that social support may provide a buffer for burnout experienced by student clinicians

Considerations Concerning the QCD Corrections to Δρ\Delta\rho

Using recent results of Avdeev et al. and an expansion for \mu_t/\mms ($M_t$ is the pole mass and $\mu_t\equiv \hat{m_t}(\mu_t)$ ), it is shown that when deltarho is expressed in terms of $\hat{m_t}^2(M_t)$, the QCD correction is only $(2-3)\times 10^{-3}$ in the NLO approximation. As a consequence, in terms of $M_t^2$ the correction to \dr is almost entirely contained in \mmss/M_t^2, a pure QCD effect. The latter is studied using various optimization procedures, and the results compared with the expansion proposed by Avdeev et al.. Implications for \ew physics are discussed. Threshold effects are analyzed on the basis of a simple sum rule.Comment: 11 pages plain LaTeX including 2 table

Gluino Contribution to the 3-loop Quark Mass Anomalous Dimension in the Minimal Supersymmetric Standard Model

We deduce the gluino contribution to the three-loop QCD quark mass anomalous dimension function within the minimal supersymmetric Standard Model (MSSM) from its standard QCD expression. This work is a continuation of the program of computation of MSSM renormalization group functions.Comment: 8 pages, RevTex, 2 Postscript figure

Higher Moments of Heavy Quark Vacuum Polarization

We present analytical calculation of the first seven moments of the heavy quark vacuum polarization function in the three-loop order. The obtained results are compared against the asymptotic formulas following from the threshold singularities. We also discuss the $\mu$ dependence of the moments within the BLM procedure.Comment: 9 pages, LaTeX, no figures, sprocl.sty provided (To appear in the Proceedings of the Second Workshop on Continuous Advances in QCD, Minneapolis, U.S.A., March 1996).

Reflection of Ethnocultural Peculiarities in French and Georgian Paremies Composed of Phytonyms

The object of our research is the comparative-contrastive study of the paremies composed of French and Georgian phytomyms, their semantic classification and description of ethnic peculiarities. The proverbs discussed here will make certain impression about the peculiar features of national vision of the two historically and mentally different peoples. On the basis of such approach it becomes possible to identify different ethnic cultures with the above said aspect (to determine the ethnical individuality of each of them) and, on the basis of the analysis of empirical material given in the article, to determine the similarities and differences in these non-related languages and their cultural characteristic features. The research given in the article is important and interesting for the researchers in paremiology generally as well as linguists working in linguo-cultural and ethno-cultural studies.

Violations of universality in a vectorlike extension of the standard model

Violations of universality of couplings in a vectorlike extension of the standard model with three heavy mirror fermion families are considered. The recently observed discrepancies between experiments and the standard model in the hadronic branching fractions $R_b$ and $R_c$ of the Z-boson are explained by the mixing of fermions with their mirror fermion partners.Comment: latex2e, 11 page
