The Effects of Majorana Phases in Estimating the Masses of Neutrinos
Majorana CP violating phases coming from heavy right-handed Majorana mass
matrices () are considered to estimate the masses of neutrinos.The
effects of phases on quasi-degenerate neutrinos mass matrix obeying
- symmetry predicts the results consistent with observations for (i)
solar mixing angle() below TBM, (ii) absolute neutrino mass
parameters[] in neutrinoless double beta () decay, and
(iii) cosmological upper bound . Analysis is carried out through
parameterization of light left-handed Majorana neutrino matrices
using only two unknown parameters within -
symmetry. We consider the charge lepton and up quark matrices as diagonal form
of Dirac neutrino mass matrix , and are genrated using
through inversion of Type-I seesaw formula. The analysis shows that
the masses of neutrinos are in agreement with the upper bound from cosmology
and neutrinoless double beta decay. The results presented in this article will
have important implications in discriminating the neutrinos mass models.Comment: arXiv admin note: substantial text overlap with arXiv:1206.343
“Why Didn’t You Just Ask?” Underestimating the Discomfort of Help-Seeking
Across four studies we demonstrate that people in a position to provide help tend to underestimate the role that embarrassment plays in decisions about whether or not to ask for help. As a result, potential helpers may overestimate the likelihood that people will ask for help (Studies 1 and 2). Further, helpers may be less inclined to allocate resources to underutilized support programs than help-seekers because they are less likely to attribute low levels of use to help-seekers’ concerns with embarrassment (Study 3). Finally, helpers may misjudge the most effective means of encouraging help-seeking behavior - emphasizing the practical benefits of asking for help, rather than attempting to assuage help-seekers’ feelings of discomfort (Study 4)
Psychological type preferences of female Bible College students in England
A sample of 122 female students attending a Pentecostal Bible College in England completed Form G (Anglicised) of the Myers-Briggs Type Indicator (MBTI). The data demonstrated preferences for extraversion over introversion, for sensing over intuition, for feeling over thinking, and for judging over perceiving. The predominant type was ISFJ (16%), followed by ESFJ (12%). Comparison with the population norms demonstrated an over-representation of intuitives among this sample of Bible College students
Gene Therapy in Cardiac Arrhythmias
Gene therapy has progressed from a dream to a bedside reality in quite a few human diseases. From its first application in adenosine deaminase deficiency, through the years, its application has evolved to vascular angiogenesis and cardiac arrhythmias. Gene based biological pacemakers using viral vectors or mesenchymal cells tested in animal models hold much promise. Induction of pacemaker activity within the left bundle branch can provide stable heart rates. Genetic modification of the AV node mimicking beta blockade can be therapeutic in the management of atrial fibrillation. G protein overexpression to modify the AV node also is experimental. Modification and expression of potassium channel genes altering the delayed rectifier potassium currents may permit better management of congenital long QT syndromes. Arrhythmias in a failing heart are due to abnormal calcium cycling. Potential targets for genetic modulation include the sarcoplasmic reticulum calcium pump, calsequestrin and sodium calcium exchanger.Lastly the ethical concerns need to be addressed
Quasi-Degenerate Neutrino Masses with Normal and Inverted Hierarchy
The effects of CP-phases on the three absolute quasi-degenerate Majorana
neutrino (QDN) masses are stud-ied with neutrino mass matrices obeying {\mu} -
{\tau} symmetry for normal as well as inverted hierarchical mass patterns. We
have made further investigations on 1) the prediction of solar mixing angle
which lies below tri-bimaximal mixing value in consistent with neutrino
oscillation observational data, 2) the prediction on absolute neutrino mass
parameter (mee) in 0{\nu}{\beta}{\beta} decay, and 3) cosmological bound on the
sum of the three absolute neutrino masses. The numerical analysis is carried
out through the parameterization of neu- trino mass matrices using only two
unknown parameters ({\epsilon}, {\eta}) within {\mu} - {\tau} symmetry. The
results show the validity of QDN mass models in both normal and inverted
hierarchical patterns. These models are far from discrimination and hence not
yet ruled out. The results presented in this article are new and have subtle
ef- fects in the discrimination of neutrino mass models.Comment: 8 pages, gave a contributory Talk at Ist IAS-CERN Singpore, Jan 2012;

Growth or decline in the Church of England during the decade of Evangelism: did the Churchmanship of the Bishop matter?
The Decade of Evangelism occupied the attention of the Church of England throughout the 1990s. The present study employs the statistics routinely published by the Church of England in order to assess two matters: the extent to which these statistics suggest that the 43 individual dioceses finished the decade in a stronger or weaker position than they had entered it and the extent to which, according to these statistics, the performance of dioceses led by bishops shaped in the Evangelical tradition differed from the performance of dioceses led by bishops shaped in the Catholic tradition. The data demonstrated that the majority of dioceses were performing less effectively at the end of the decade than at the beginning, in terms of a range of membership statistics, and that the rate of decline varied considerably from one diocese to another. The only exception to the trend was provided by the diocese of London, which experienced some growth. The data also demonstrated that little depended on the churchmanship of the diocesan bishop in shaping diocesan outcomes on the performance indicators employed in the study
