Dilepton Production at Fermilab and RHIC

Some recent results from several fixed-target dimuon production experiments at Fermilab are presented. In particular, we discuss the use of Drell-Yan data to determine the flavor structure of the nucleon sea, as well as to deduce the energy-loss of partons traversing nuclear medium. Future dilepton experiments at RHIC could shed more light on the flavor asymmetry and possible charge-symmetry-violation of the nucleon sea. Clear evidence for scaling violation in the Drell-Yan process could also be revealed at RHIC.Comment: 5 pages, talk presented at the RIKEN-BNL Workshop on 'Hard Parton Physics in Nucleus-Nucleus collisions, March 199

Suppression of Quarkonium Production in Heavy Ion Collisions at RHIC and LHC

A model for the production of quarkonium states in the midrapidity region at RHIC and LHC energy range is presented which explores well understood properties of QCD only. An increase of the quarkonium hadronisation time with the initial energy leads to a gradual change of the most important phenomena from fixed target- to collider-energies. We evaluate nuclear effects in the quarkonium production due to medium modification of the momentum distribution of the heavy quarks produced in the hard interactions, i.e. due to the broadening of the transverse momentum distribution. Other nuclear effects, i.e. nuclear shadowing and parton energy loss, are also evaluated.Comment: 5 pages, 1 table, 1 figure, Contribution to the Proceedings of the V International Conference on Strangeness in Quark Matter July 20-25, 2000 Berkeley, Californi

MIS versus Computer Science: An Empirical Comparison of the Influences on the Students’ Choice of Major

A history of declining enrollments in university Management Information Systems (MIS) and computer science (CS) departments in the U.S. considerably impacts both college departments and business organizations that hire graduates. In order to reverse the enrollment trend, an understanding of the important similarities and differences that shape a student’s decision to major in MIS or CS will allow departments to better promote their major, formulate more effective strategies for reaching interested and undecided students, and enhance the fit between student and career. This study directly compared important influences on choice of major for 205 MIS and CS majors at four US universities. Results indicate that the most important influences for both MIS and CS students are interest in technology and monetary compensation. MIS majors, however, are significantly more influenced by others, especially college instructors, parents, friends, and the desire to interact with others. They are also more interested in business and business organizations. CS majors, on the other hand, are more interested in the technology itself and tend to choose CS as a major either in high school or shortly thereafter. Based on these findings, recommendations are provided to aid college departments in attracting and retaining appropriate majors

Intermediate- and high-energy reactions of uranium with neon and carbon

Target fragment production from the interactions of 1.0, 3.0, 4.8, and 12 GeV /sup 12/C and 5.0, 8.0, 20, and 42 GeV /sup 20/Ne with uranium has been measured using off-line gamma-ray spectroscopic techniques. The experimental charge and mass yield distributions are generally consistent with the concepts of limiting fragmentation and factorization at energies of 3.0 GeV and above. The total projectile kinetic energy was found to be the relevant scaling parameter for the comparison of reactions induced by projectiles of different sizes. Light fragments with mass number less than 60 were found to violate limiting fragmentation, and had excitation functions that were strongly increasing with projectile energy until 8.0 to 12.0 GeV. With the 1.0 GeV /sup 12/C beam the pattern of mass yields was quite different from that of all the other reactions, with the normal peak in the fission mass region (80 < A < 145), but with much lower yields below mass number 60 and between mass numbers 145 and 210, indicating that these fragments are formed primarily in very energetic reactions in which large excitation energies are transferred to and significant amounts of mass are removed from the target nucleus. Theoretical predictions of the intra-nuclear cascade, nuclear fireball, and nuclear firestreak models are compared with the experimental results. The intra-nuclear cascade and nuclear firestreak models are both able to predict the general shapes of the experimental distributions, with the exception of the yields for the lightest fragments

SELECTING A BUSINESS MAJOR WITHIN THE COLLEGE OF BUSINESS

This study employed a survey in examining the important influences that shape a student’s selection of a major in the College of Business (COB). In particular, it compared these influences, by major, to assess which items were most (and least) important to the students majoring in accounting, general business, finance, management, marketing, and MIS. The influences, totaling 37, included internal influences (e.g., interest in the field), external influences (e.g., projected salary), and interpersonal influences (influence of significant others). Some of the findings were consistent with those of prior studies. For example, interesting work was highly important for all business majors, and specific interpersonal influences such as parents, high school teachers, and peers were relatively unimportant. The findings presented herein suggest that the overall impact of interpersonal influence may have been underestimated in previous studies. Unlike many previous studies, this study showed that job availability and job security were more important to students than interest in the field. This study augments the extant literature in that the survey was conducted right after the 2009 recession, which allowed an analysis of student decision making during a period of high unemployment and lingering economic uncertainty. Implications and suggestions for further research are discussed

Seniors and Information Technology: A MIS-Fit?

The “digital divide” between the haves and have-nots in society continues to draw attention in traditional media outlets as well as academic research. Those yearning to join the computer revolution comprise several groups defined by wealth, ethnicity, country (even regions of countries), and age. While there has been research into the digital divide in all of these areas, the focus of this paper is Information Technology (IT) use by the elderly, or our senior citizens. Our interest in this group stems from the dynamic interaction of two forces: 1) senior populations are growing in percentage and sheer number both in the United States and internationally; and 2) as a group, the elderly have more disposable income to spend on IT than their younger counterparts. In order to coordinate our research agenda, the current investigation presents a framework that delineates scholarly inquiry into this topic by the elements of the framework. We look at what has been done, and what we feel needs to be done, in order to incorporate an important demographic group into the mainstream of computing society: our seniors

Partonic Energy Loss and the Drell-Yan Process

We examine the current status of the extraction of the rate of partonic energy loss in nuclei from A dependent data. The advantages and difficulties of using the Drell-Yan process to measure the energy loss of a parton traversing a cold nuclear medium are discussed. The prospects of using relatively low energy proton beams for a definitive measurement of partonic energy loss are presented.Comment: 12 pages, 2 figure
