Do narcissism and emotional intelligence win us friends? Modeling dynamics of peer popularity using inferential network analysis

This research investigated effects of narcissism and emotional intelligence (EI) on popularity in social networks. In a longitudinal field study we examined the dynamics of popularity in 15 peer groups in two waves (N=273).We measured narcissism, ability EI, explicit and implicit self-esteem. In addition, we measured popularity at zero acquaintance and three months later. We analyzed the data using inferential network analysis (temporal exponential random graph modeling, TERGM) accounting for self-organizing network forces. People high in narcissism were popular, but increased less in popularity over time than people lower in narcissism. In contrast, emotionally intelligent people increased more in popularity over time than less emotionally intelligent people. The effects held when we controlled for explicit and implicit self-esteem. These results suggest that narcissism is rather disadvantageous and that EI is rather advantageous for long-term popularity

An amino acid transporter involved in gastric acid secretion

Gastric acid secretion is regulated by a variety of stimuli, in particular histamine and acetyl choline. In addition, dietary factors such as the acute intake of a protein-rich diet and the subsequent increase in serum amino acids can stimulate gastric acid secretion only through partially characterized pathways. Recently, we described in mouse stomach parietal cells the expression of the system L heteromeric amino acid transporter comprised of the LAT2-4F2hc dimer. Here we address the potential role of the system L amino acid transporter in gastric acid secretion by parietal cells in freshly isolated rat gastric glands. RT-PCR, western blotting and immunohistochemistry confirmed the expression of 4F2-LAT2 amino acid transporters in rat parietal cells. In addition, mRNA was detected for the B0AT1, ASCT2, and ATB(0+) amino acid transporters. Intracellular pH measurements in parietal cells showed histamine-induced and omeprazole-sensitive H+-extrusion which was enhanced by about 50% in the presence of glutamine or cysteine (1mM), two substrates of system L amino acid transporters. BCH, a non-metabolizable substrate and a competitive inhibitor of system L amino acid transport, abolished the stimulation of acid secretion by glutamine or cysteine suggesting that this stimulation required the uptake of amino acids by system L. In the absence of histamine glutamine also stimulated H+-extrusion, whereas glutamate did not. Also, phenylalanine was effective in stimulating H+/K+-ATPase activity. Glutamine did not increase intracellular Ca2+ levels indicating that it did not act via the recently described amino acid modulated Ca2+-sensing receptor. These data suggest a novel role for heterodimeric amino acid transporters and may elucidate a pathway by which protein-rich diets stimulate gastric acid secretio

Relativistic effects in electromagnetic nuclear responses in the quasi-elastic delta region

A new non-relativistic expansion in terms of the nucleon's momentum inside nuclear matter of the current for isobar electro-excitation from the nucleon is performed. Being exact with respect to the transferred energy and momentum, this yields new current operators which retain important aspects of relativity not taken into account in the traditional non-relativistic reductions. The transition current thus obtained differs from the leading order of the traditional expansion by simple multiplicative factors. These depend on the momentum and energy transfer and can be easily included together with relativistic kinematics in non-relativistic, many-body models of isobar electro-excitation in nuclei. The merits of the new current are tested by comparing with the unexpanded electromagnetic nuclear responses in the isobar peak computed in a relativistic Fermi gas framework. The sensitivity of the relativistic responses to the isobar's magnetic, electric and Coulomb form factors and the finite width of the isobar is analyzed.Comment: 26 pages plus 6 figure

Charged Lepton Production from Iron Induced by Atmospheric Neutrinos

The charged current lepton production induced by neutrinos in $^{56}Fe$ nuclei has been studied. The calculations have been done for the quasielastic as well as the inelastic reactions assuming $\Delta$ dominance and take into account the effect of Pauli blocking, Fermi motion and the renormalization of weak transition strengths in the nuclear medium. The quasielastic production cross section for lepton production are found to be strongly reduced due to nuclear effects while there is about 10% reduction in the inelastic cross sections in the absence of the final state interactions of the pions. The numerical results for the momentum and angular distributions of the leptons averaged over the various atmospheric neutrino spectra at the Soudan and Gransasso sites have been presented. The effect of nuclear model dependence and the atmospheric flux dependence on the relative yield of ${\mu}$ to e has been studied and discussed.Comment: 16pages, 18figure

Reluctance Toward Online Teaching

Online education has become a staple in the American higher education system. A shortage of qualified and motivated online instructors exists as online learning demand increases. The purpose of this qualitative study was to identify why faculty members are not motivated to teach online courses. This study sought to answer the following three questions: (1) Why are faculty members not participating in online instruction? (2) What incentives, if any, are likely to motivate non-participating instructors to adopt online instruction? and (3) What are the differences in perceptions regarding online instruction between faculty members who had been asked or had an opportunity to teach online and refused and faculty members who had tried online instruction and no longer teach online? Using a basic qualitative research design, I interviewed 20 unlimited, full-time faculty members of community and technical colleges who had been asked or had the opportunity to teach online and refused or who had tried teaching online and discontinued doing so. Through these interviews, I gained valuable insight into elements that hinder the motivation of community and technical college faculty members for teaching online. I further identified some factors that may motivate faculty members to embrace online instruction

Real People Acting Out Interpersonal Issues With Paper Representations

In this thesis body of work, I have interacted and collaborated with five friends to create images exploring human relationships. The subject matter illustrates my friends and myself acting out interpersonal issues with paper representations of one another. It has been my aim to represent my imagery in a campy thematic way. I include a discussion of the images in my body of work from both my perspective and the perspective of my models. The figurative paper images stand in as representatives of the genders of their subjects. I have explored multiple points of view, constructing, reconstructing and deconstructing complex compositions; experimenting with a variety of focal points; and I have increased my knowledge of lighting and color effects through digital manipulation

The IS Core-I: Economic and Systems Engineering Approaches to IS Identity

This article presents an economic basis for declaring Information Systems and Information Technology to be both cognitively and socio-politically legitimate and to show that learning [Benbasat and Zmud, 2003] has been achieved The large scale complexity and diversity of today\u27s information systems are discussed within the context of a software engineering (SE) model and the higher-level view of the product that SE provides. The history and scope of investments in computing, and the practices of software engineering demonstrate that we are not a New Collective suffering from an identity crisis. We are a heterogeneous group looking at a wide diversity of Information Systems, some of which challenge the way we think about organizational boundaries and show that artifacts are not adequate to define IT
