James Michaels (A) and (B)

This two-part case describes a challenging and painful period for James Michaels, a young and openly gay assistant professor of computer science at a small Midwestern liberal arts college. To James’s surprise and disgust, a male student harasses him using a homophobic slur in an e-mail. The case chronicles not only the harassment incident, but also how college administrators and faculty colleagues handle this allegation. James soon finds himself in complete disappointment with the outcome and unsure how to proceed. He perceives that the college administrators, along with some of his colleagues, discount the severity of the harassment incident and in doing so disregard his rights and fail to hold the offending student fully accountable for such policy-violating behavior. Students assigned this case, taking into account James’s perspective, are asked to identify and recommend specific strategies to achieve justice and accountability in this context

Teaching Note: James Michaels (A) and (B)

This teaching note is an accompaniment to the case “James Michaels (A) and (B).” It is designed specifically for management educators to use as a guide when assigning the aforementioned case for written analyses and class discussion. In addition to a detailed synopsis and a revealing epilogue, specific teaching strategies based on the problem-based learning (PBL) method are presented. The case itself provides students a unique situation, yet one that is applicable to all types of organizational contexts. With this teaching note, management educators can further enhance their students’ learning and appreciation for the topics of employment law, homophobic harassment, organizational justice, power dynamics, or political behavior, among others. The versatility of this case invites the exploration of other applicable topics in human resource management, organizational behavior, and leadership that may emerge from student inquiry and problem solving

The effect of physical and demographic factors and training on the time-to-adoption of domestic cats in a local shelter

About 7.6 million animals enter shelters each year (Pet Statistics. (n.d.)). Many factors have been examined to determine what affects adoption rates for these companion animals. A study of a kill-shelter has found that age, gender, and circumstance all influenced cat adoption rates (Lepper et. al., 2002). Training was also found to increase the adoption rates of dogs (Luescher and Medlock, 2009). Data on cat adoptions were collected from Charlottesville-Albemarle SPCA (a no-kill shelter) and were analyzed using Sigma Plot and STATA. Training cats took place at Rockingham/Harrisonburg SPCA and the data was also analyzed using Sigma Plot. Color, age, and source were all found to influence adoption rates. None of the animals which were trained failed training, however the five which were fully trained were adopted or transferred before data could be collected. Cats which were included in the training group showed significantly fewer returns when compared to the control. The differences between adoption factors could be explained through population differences in the areas serviced by the shelters as well as by differences between the shelters themselves (kill vs no-kill)

Through the combining glass

Reflective optical combiners like beam splitters and two way mirrors are used in AR to overlap digital contents on the users' hands or bodies. Augmentations are usually unidirectional, either reflecting virtual contents on the user's body (Situated Augmented Reality) or augmenting user's reflections with digital contents (AR mirrors). But many other novel possibilities remain unexplored. For example, users' hands, reflected inside a museum AR cabinet, can allow visitors to interact with the artifacts exhibited. Projecting on the user's hands as their reflection cuts through the objects can be used to reveal objects' internals. Augmentations from both sides are blended by the combiner, so they are consistently seen by any number of users, independently of their location or, even, the side of the combiner through which they are looking. This paper explores the potential of optical combiners to merge the space in front and behind them. We present this design space, identify novel augmentations/interaction opportunities and explore the design space using three prototypes

Dress for Success in the Classroom (But what is Success to You?

This session explores the implications of how we dress in the classroom. The image that attire conveys, and how attire impacts our own sense of self, consciously and unconsciously reflects our own identities and reveals issues of identity dissonance. Finally we examine how different attire can lead to different student outcomes or different forms of success. We examine literature from management, social psychology, education, communication and others to lead discussion that we hope will allow participants to better understand and/or question how and why they dress as they do and how that can determine success… in their own terms

Antigenic and genetic evolution of contemporary swine H1 influenza viruses in the United States

Several lineages of influenza A viruses (IAV) currently circulate in North American pigs. Genetic diversity is further increased by transmission of IAV between swine and humans and subsequent evolution. Here, we characterized the genetic and antigenic evolution of contemporary swine H1N1 and H1N2 viruses representing clusters H1-α (1A.1), H1-β (1A.2), H1pdm (1A.3.3.2), H1-γ (1A.3.3.3), H1-δ1 (1B.2.2), and H1-δ2 (1B.2.1) currently circulating in pigs in the United States. The δ1-viruses diversified into two new genetic clades, H1-δ1a (1B.2.2.1) and H1-δ1b (1B.2.2.2), which were also antigenically distinct from the earlier H1-δ1-viruses. Further characterization revealed that a few key amino acid changes were associated with antigenic divergence in these groups. The continued genetic and antigenic evolution of contemporary H1 viruses might lead to loss of vaccine cross-protection that could lead to significant economic impact to the swine industry, and represents a challenge to public health initiatives that attempt to minimize swine-to-human IAV transmission

Living with multiple myeloma: A focus group study of unmet needs and preferences for survivorship care

Purpose: To describe the unmet informational, psychological, emotional, social, practical, and physical needs and preferences for posttreatment survivorship care of individuals living with multiple myeloma to inform the development of relevant, personcentered, survivorship services. Methods: An exploratory, descriptive study using 2 focus groups with 14 participants, 6 to 49 months postdiagnosis. Results: Thematic analysis revealed 7 key themes: information needs, experience with health-care professionals, coping with side effects, communicating with family and friends, dealing with emotions, support needs, and living with the chronicity of myeloma. Participants described key characteristics of survivorship care relevant to their needs and indicated they would like a more whole of person approach to follow-up when the main treatment phases had completed. Conclusion: Participants in this study described unmet needs across a breadth of domains that varied over time. The development of flexible, person-centered approaches to comprehensive survivorship care is needed to address the considerable quality-of-life issues experienced by people living with multiple myeloma. Nurse-led care may offer 1 viable model to deliver enhanced patient experience—providing the vital “link” that people described as missing from their survivorship care

Subtleties on energy calculations in the image method

In this pedagogical work we point out a subtle mistake that can be done by undergraduate or graduate students in the computation of the electrostatic energy of a system containing charges and perfect conductors if they naively use the image method. Specifically, we show that the naive expressions for the electrostatic energy for these systems obtained directly from the image method are wrong by a factor 1/2. We start our discussion with well known examples, namely, point charge-perfectly conducting wall and point charge-perfectly conducting sphere and then proceed to the demonstration of general results, valid for conductors of arbitrary shapes.Comment: 9 pages, 2 figures; Major change in this version: subsection added to Sect.4 (theorem generalization). Minor changes: title replaced; corrections to the English; some explanatory comments adde

Non-existence of normal tokamak equilibria with negative central current

Recent tokamak experiments employing off-axis, non-inductive current drive have found that a large central current hole can be produced. The current density is measured to be approximately zero in this region, though in principle there was sufficient current drive power for the central current density to have gone significantly negative. Recent papers have used a large aspect-ratio expansion to show that normal MHD equilibria (with axisymmetric nested flux surfaces, non-singular fields, and monotonic peaked pressure profiles) can not exist with negative central current. We extend that proof here to arbitrary aspect ratio, using a variant of the virial theorem to derive a relatively simple integral constraint on the equilibrium. However, this constraint does not, by itself, exclude equilibria with non-nested flux surfaces, or equilibria with singular fields and/or hollow pressure profiles that may be spontaneously generated.Comment: 5 pages, 3 figures.

Collecting single molecules with conventional optical tweezers

The size of particles which can be trapped in optical tweezers ranges from tens of nanometres to tens of micrometres. This size regime also includes large single molecules. Here we present experiments demonstrating that optical tweezers can be used to collect polyethylene oxide (PEO) molecules suspended in water. The molecules that accumulate in the focal volume do not aggregate and therefore represent a region of increased molecule concentration, which can be controlled by the trapping potential. We also present a model which relates the change in concentration to the trapping potential. Since many protein molecules have molecular weights for which this method is applicable the effect may be useful in assisting nucleation of protein crystals.Comment: 5 pages, 4 figure
