Special Issue on the AMCIS 2001 Workshops: Introduction

This article introduces the CAIS special issue on the workshops presented at AMCIS 2001 in Boston, MA. The overriding theme of this issue deals with various aspects of teaching with technology in the information systems curriculum using commercial applications as well as cases developed by faculty. These aspects include challenges of integrating large-scale applications with limited resources, system design configurations, and pedagogical issues. This paper provides an overview of each of the articles in this issue

Facebook Use Among African American and Hispanic Students: An Exploratory Investigation of Perceived Academic Impact

Facebook is one of the world’s leading social networking sites. It is pervasive in students’ lives and can impact their academic careers in a variety of ways. However, little research exists evaluating the use of Facebook in minority academic settings. An early step in this direction is to gain an understanding of how different student demographic groups use Facebook. An interest in further assessment of Facebook’s role in diverse segments of academia motivates the collection and analysis of Facebook-related data from minority serving institutions such as Historically Black Colleges or Universities (HBCUs) and Hispanic Serving Institutions (HSIs). This study presents the results of a comparative examination of African American students at an HBCU and Hispanic students at an HSI regarding their perceptions of Facebook use for academics. The findings reveal significant differences between the two groups. When compared to African American students, the Hispanic students use Facebook more for academics even though they perceive it to have a negative impact on academics. This perceived negative impact of Facebook is not directly translated into actual differences in self-reported GPA

Facebook Privacy Attitudes: A Comparison of Two Minority Groups

Because of Facebook’s ubiquitous nature, users who fail to properly configure their Facebook account privacy settings could be unintentionally revealing personal information to millions of people. This study analyzes data collected from African American and Hispanic college students regarding Facebook privacy setting attitudes and use. The findings indicate African American students have been members of Facebook longer and have more “Friends” than Hispanic students. Both ethnic groups spend about the same amount of time on Facebook during each session, although Hispanics log on more frequently. Virtually all the students claim awareness and use Facebook privacy settings. Hispanics have more restrictive Facebook privacy settings than African Americans. Neither ethnic group trusts Facebook to protect privacy, but African Africans show less concern while Hispanics indicate greater worry about Facebook privacy and data security. Both ethnic groups are more concerned about Internet privacy than Facebook privacy, Hispanics significantly more so

A Re-Examination of Racioethnic Imbalance of IS Doctorates: Changing the Face of the IS Classroom

There is an extremely low percentage of minority faculty in the IS field. This global trend is highly conspicuous-- a minority of blacks compared to a majority of white academics in England, a minority of Aborigines compared to a majority of white academics in Australia, a minority of blacks compared to a majority of white academics in Canada, and for the purpose of our study, a minority of Native American, Hispanic American, and African American academics compared to a majority of white academics in the United States. Between 1995-2000, not only do AACSB reports indicate a continuous decline in minority business doctorates, but the accreditation body reports that the IS discipline shows a significant under-representation of minority faculty. In this study, we argue that mentoring under-represented groups in the discipline offers the field a myriad of avenues to change the ¡°face¡± of the classroom and reduce this gap. We examine the absence of racioethnicity and mentoring in the IS field and offer lessons learned from the Ph.D. Project Model for engendering change and mentoring within the IS community. Using data from a six-year period, we discuss diversity issues, lessons learned, and recommendations from mentoring a group of under-represented IS doctoral students

Examination of Fluconazole-Induced Alopecia in an Animal Model and Human Cohort.

Fluconazole-induced alopecia is a significant problem for patients receiving long-term therapy. We evaluated the hair cycle changes of fluconazole in a rat model and investigated potential molecular mechanisms. Plasma and tissue levels of retinoic acid were not found to be causal. Human patients with alopecia attributed to fluconazole also underwent detailed assessment and in both our murine model and human cohort fluconazole induced telogen effluvium. Future work further examining the mechanism of fluconazole-induced alopecia should be undertaken

Histamine stimulates the proliferation of small and large cholangiocytes by activation of both IP3/Ca2+ and cAMP-dependent signaling mechanisms

Although large cholangiocytes exert their functions by activation of cyclic adenosine 3',5'-monophosphate (cAMP), Ca(2+)-dependent signaling regulates the function of small cholangiocytes. Histamine interacts with four receptors, H1-H4HRs. H1HR acts by Gαq activating IP(3)/Ca(2+), whereas H2HR activates Gα(s) stimulating cAMP. We hypothesize that histamine increases biliary growth by activating H1HR on small and H2HR on large cholangiocytes. The expression of H1-H4HRs was evaluated in liver sections, isolated and cultured (normal rat intrahepatic cholangiocyte culture (NRIC)) cholangiocytes. In vivo, normal rats were treated with histamine or H1-H4HR agonists for 1 week. We evaluated: (1) intrahepatic bile duct mass (IBDM); (2) the effects of histamine, H1HR or H2HR agonists on NRIC proliferation, IP(3) and cAMP levels and PKCα and protein kinase A (PKA) phosphorylation; and (3) PKCα silencing on H1HR-stimulated NRIC proliferation. Small and large cholangiocytes express H1-H4HRs. Histamine and the H1HR agonist increased small IBDM, whereas histamine and the H2HR agonist increased large IBDM. H1HR agonists stimulated IP(3) levels, as well as PKCα phosphorylation and NRIC proliferation, whereas H2HR agonists increased cAMP levels, as well as PKA phosphorylation and NRIC proliferation. The H1HR agonist did not increase proliferation in PKCα siRNA-transfected NRICs. The activation of differential signaling mechanisms targeting small and large cholangiocytes is important for repopulation of the biliary epithelium during pathologies affecting different-sized bile ducts

Multilevel Structural Equation Modeling of Students’ Dietary Intentions/Behaviors, BMI, and the Healthfulness of Convenience Stores

When dietary behaviors are habitual, intentions are low, and environmental cues, such as the consumer food environment, might guide behavior. How might intentions to eat healthily and ultimately actual dietary behaviors, be influenced by the consumer food environment (including the availability and affordability of healthy foods) in convenience stores? This study will determine pathways between the healthfulness of convenience stores and college students' dietary intentions/behaviors, and body mass index (BMI)
