Tidally Triggered Star Formation in Close Pairs of Galaxies: Major and Minor Interactions
We study star formation in a sample of 345 galaxies in 167 pairs and compact
groups drawn from the original CfA2 Redshift Survey and from a follow-up search
for companions. We construct our sample with attention to including pairs with
luminosity contrast |\Delta m_R| >= 2. These 57 galaxies with |\Delta m_R| >= 2
provide a set of nearby representative cases of minor interactions, a central
feature of the hierarchical galaxy formation model. Here we report the
redshifts and positions of the 345 galaxies in our sample, and of 136 galaxies
in apparent pairs that are superpositions. In the pairs sample as a whole,
there are strong correlations between the equivalent width of the H\alpha
emission line and the projected spatial and the line-of-sight velocity
separation of the pair. For pairs of small luminosity contrast, |\Delta m_R| <
2, the member galaxies show a correlation between the equivalent width of
H\alpha and the projected spatial separation of the pair. However, for pairs
with large luminosity contrast, |\Delta m_R| >= 2, we detect no correlation
between the equivalent width of H\alpha and the projected spatial separation.
The relative luminosity of the companion galaxy is more important in a
gravitational tidal interaction than the intrinsic luminosity of the galaxy.
Central star formation across the entire pairs sample depends strongly on the
luminosity ratio, |\Delta m_R|, a reasonable proxy for the mass ratio of the
pair; pairs composed of similarly luminous galaxies produce the strongest
bursts of star formation. Pairs with |\Delta m_R| >= 2 rarely have EW(H\alpha)

Vol. 27 No. 3 (Autumn 2016), DOI 10.18060/21388 Building an Engagement Center through Love of Place: The Story of the Barbara Weitz Community Engagement Center
Universities throughout the United States operate engagement centers to extend campus faculty, staff and student resources to their communities. In 2014, the University of Nebraska Omaha (UNO) opened the Barbara Weitz Community Engagement Center (Weitz CEC): a privately funded $24 million, 70,000 square foot facility located in the middle of its original Dodge Street campus. In addition to offices for its service learning and community service enterprises, the CEC houses over thirty university and community organizations and offers extensive space for meetings, dialogue and collaboration. This paper will discuss its strategic and programmatic origins, unique design, and lessons learned in developing and operating the center
PROFESSIONAL REFERRALS: KEEPING-WHILE-GIVING, RECIPROCATION, AND THE TRANSFER OF OPPORTUNITIES AMONG ENTREPRENEURIAL PROFESSIONALS
Through inductive research, I explored the dynamic process between entrepreneurial professionals in sending and receiving professional referrals. I define a professional referral as an entrepreneurial professional advising a client to instead do business with a specific other professional within the same industry. While considering the needs of the client, these entrepreneurs involved in the professions must transfer a valuable opportunity to a competitor. Prior research indicates that entrepreneurial professionals should refer opportunities based on skill and specialty, should receive fees for referrals, and should select referral recipients based on tie formation mechanisms, trust, and reputation protection. Yet professional referrals involve unique complexities, as they occupy a vague conceptual space between economic and social exchange. This paper addresses the interplay of these obligations. By using a grounded theory methodology, I was able to generate an emergent model and mid-level theory. I interviewed 42 lawyers, using semi-structured interviews.
The model is arranged into three transitional decisions: refer the opportunity, select a referral recipient, and establish (or terminate) a referral routine. For the first decision, in addition to referrals based on objective skill and specialty, I found that entrepreneurial professionals will refer business on subjective costs, including emotional toll and being morally compromised; I term this new dimension social referrals. Next, the entrepreneurial professional must decide to whom the referral will be sent. I found that entrepreneurial professionals are possessive of their clients, as each client represents a long-term revenue stream. Possessiveness results in reciprocity expectations, the most important of which is keeping-while-giving, or the expectation of the return of the same client relationship. Entrepreneurial professionals also set dependability expectations. Expectations directly impact selection, and these relationships are amplified by the presence of tie formation mechanisms. Finally, entrepreneurial professionals establish referral routines; they repeatedly send their referral business to no more than three individuals within a given dimension for exchange. Breaching reciprocity and dependability expectations can cause routines to be terminated, but overall, this final transitional decision occurs by default and can continue indefinitely. These interconnected steps combine to form a middle-range theory of professional referral dynamics

Acceptance and Continuance Usage Intention of Mixed Reality for Australian Healthcare Interprofessional Education
Virtual-Reality and augmented-reality are becoming innovative teaching and learning approaches across many industries, including healthcare, especially during the COVID-19 pandemic. However, the adoption rate of this technology is very low, especially in Australian healthcare Interprofessional Education. This study investigates factors influencing adoption and use of mixed-reality technology for Australian healthcare IPE. In this study, a theoretical model based on the Expectation and Confirmation Model and Task Technology Fit is developed and will be tested to determine Australian healthcare professionalsâ intentions to continue using mixed-reality for Interprofessional Education through three validated surveys using a voluntary non-probability sampling strategy, over a 10-week period, targeting 124 healthcare professionals at the Tweed hospital, NSW Australia. The research outcome will assist in determining the validity of the proposed hybrid model in the context of MR healthcare training. It may assist in developing a more suitable theoretical framework and future characteristics of MR for healthcare training
Love of Place: The Metropolitan University Advantage: 2015 CUMU National Conference in Omaha
The theme for the 2015 CUMU National Conference in Omaha, NE was âLove of Place: The Metropolitan University Advantageâ. The 2015 theme celebrates key elements that establish the identity of metropolitan universities and CUMU as an organization. The theme recognizes the unique opportunities and benefits provided by metropolitan universities for students and communities. Metropolitan universities provide students with enriching educational experiences while contributing to building and strengthening the community. These enriched experiences also support faculty and staff growth as members of the university and community. The theme encouraged conference participants to explore new pedagogical approaches, strategies for sustaining meaningful partnerships, and opportunities for successful engagement of the community by examining the transformative power of the relationships between metropolitan universities and their âplace.â Essential to this theme is the notion of stewardship and being good stewards of the communities that we live in, that bless our lives, our families, and our universities. The special issue devoted to the theme and notion of âLove of Placeâ provides an overview of the stewardship witnessed at the conference and then launches into the full article contributions that illustrate the âLove of Placeâ exemplified by the great presenters and the many initiatives occurring across the CUMU
