The Perception of Black Male Students of Black Faculty/Staff Involvement in Mentorship at a Predominantly White Institution

This research study explored the perception African American men had of mentorship, its value to their education and the effects it had on their college success at a predominantly White institution. The study further focused on the impact mentorship had on the student when the mentor was of a different race versus the same race of the student. The research was guided by the following questions: (1) What is the value of mentorships related to attending a higher education institution, (2) What factors lead Black male students to seek mentorships, (3) What are the perceived differences between mentorship with cross-race faculty/staff and Black male faculty/staff, and (4) What is the Black males\u27 perception of the role of mentorship to their success? From each research question posed several themes emerged: guidance, growth, acceptance, retention, feeling unsupported, sense of belonging, barriers such as uncomfortableness, white faculty/staff reticence, stereotypes, and lastly mentorship roles that bridge the gap and provide encouragement and company. Research revealed that students perceived mentoring to be of great value to their college experience. Although not mutually exclusive, it was also determined that having access to Black faculty/staff also played a major role in the student\u27s retention and satisfaction at the PWI. Even though all of the participants interviewed expressed feeling comfortable with White faculty/staff, they also identified barriers to seeking mentorship. Feelings of segregation, being stereotyped, and judged led these students to seek mentorship with Black faculty/staff who they believed could identify with their strife and provide them with encouragement to overcome these obstacles. Recommendations include developing multicultural competency programming for faculty/staff to properly address the needs of Black male students, providing comfortable spaces for Black males to express and address their feelings, and the hiring of more Black faculty/staff to assist in their development and serve as role models

Guided ion beam studies of the reactions of Crn+ (n=1-18) with CO2: chromium cluster oxide bond energies

Journal ArticleThe kinetic energy dependence of the reactions of Crn+ (n=1-18) with CO2 are studied in a guided ion beam mass spectrometer. The primary product ions are CrnO+, which then decompose by sequential loss of chromium atoms as the kinetic energy is increased. Simple collision-induced dissociation to form the Crn+-1 product ions is also observed. Large cluster ions, n≥9, form the CrnCO2+ adduct at low kinetic energies

Guided ion beam studies of the reactions of Crn + (n=2-18) with O2: chromium cluster oxide and dioxide bond energies

Journal ArticleThe kinetic energy dependence of the reactions of Crn+ (n=2-18) with O2 are studied in a guided ion beam mass spectrometer. A variety of CrmO2+, CrmO+, and Crm+ product ions, where m≤n, are observed, with the dioxide cluster ions dominating the products for all larger reactant cluster ions. Reaction efficiencies are near unity for all but the smallest clusters. The energy dependence of the product cross sections is analyzed in several different ways to determine thermochemistry for both the first and second oxygen atom binding to chromium cluster ions. These values show little dependence on cluster size for clusters larger than three atoms. The trends in this thermochemistry are discussed and compared to bulk phase oxidation values

Obsidian Samples from Archaeological Sites in Northwestern Alaska: A Preliminary Report

Reports the Na and Mn contents and Na/Mn ratios, determined by neutron activation analyses of 103 obsidian samples from the Onion Portage and nine related archeological sites. The occurrence and stratigraphic distribution are noted of four groups of obsidian distinguished by Mn content and Na/Mn ratio. Group B, the largest, appears in a complex with an age of 4000-3900 BC and in another of 1000-1700 AD, group A in complexes dating at 2600-2200 and 1500-500 BC, group C occurs 2200-1800 BC; and group D 400-1700 AD. There are at least four obsidian sources represented whose geographic locations are unknown

Thermodynamic signatures for the existence of Dirac electrons in ZrTe5

We combine transport, magnetization, and torque magnetometry measurements to investigate the electronic structure of ZrTe5 and its evolution with temperature. At fields beyond the quantum limit, we observe a magnetization reversal from paramagnetic to diamagnetic response, which is characteristic of a Dirac semi-metal. We also observe a strong non-linearity in the magnetization that suggests the presence of additional low-lying carriers from other low-energy bands. Finally, we observe a striking sensitivity of the magnetic reversal to temperature that is not readily explained by simple band-structure models, but may be connected to a temperature dependent Lifshitz transition proposed to exist in this material.Comment: 5 pages, 4 figure
