Delineation Of Precursors In Murine Spleen That Develop In Contact With Splenic Endothelium To Give Novel Dendritic-Like Cells., Jonathan Tan, Pravin Periasamy, Helen O'Neill
Delineation Of Precursors In Murine Spleen That Develop In Contact With Splenic Endothelium To Give Novel Dendritic-Like Cells., Jonathan Tan, Pravin Periasamy, Helen O'Neill

Hematopoietic cell lineages are best described in terms of distinct progenitors with limited differentiative capacity. To distinguish cell lineages, it is necessary to define progenitors and induce their differentiation in vitro. We previously reported in vitro development of immature dendritic-like cells (DCs) in long-term cultures (LTCs) of murine spleen, and in cocultures of spleen or bone marrow (BM) over splenic endothelial cell lines derived from LTCs. Cells produced are phenotypically distinct CD11b(hi)CD11c(lo)CD8(-)MHC-II(-) cells, tentatively named L-DCs. Here we delineate L-DC progenitors as different from known DC progenitors in BM and DC precursors in spleen. The progenitor is contained within the …
Haematopoietic Stem Cells In Spleen Have Distinct Differentiative Potential For Antigen Presenting Cells., Jonathan Tan, Helen O'Neill
Haematopoietic Stem Cells In Spleen Have Distinct Differentiative Potential For Antigen Presenting Cells., Jonathan Tan, Helen O'Neill
Jonathan Tan
Dendritic cells (DC) are known to develop from macrophage dendritic progenitors (MDP) in bone marrow (BM), which give rise to conventional (c)DC and monocytes, both dominant antigen presenting cell (APC) subsets in spleen. This laboratory has however defined a distinct dendritic-like cell subset in spleen (L-DC), which can also be derived in long-term cultures of spleen. In line with the restricted in vitro development of only L-DC in these stromal cultures, we questioned whether self-renewing HSC or progenitors exist in spleen with restricted differentiative capacity for only L-DC. Neonatal spleen and BM were compared for their ability to reconstitute mice …

Service Learning Across The Curriculum: A Collaboration To Promote Smoking Cessation, Jean Grow, Joyce Wolburg
Service Learning Across The Curriculum: A Collaboration To Promote Smoking Cessation, Jean Grow, Joyce Wolburg
Jean Grow
This paper focuses on how pedagogy, service, and scholarship can be combined across the advertising curriculum through service learning, which invigorates collaboration among faculty members, student teams, and advertising professionals. The authors demonstrate how service learning projects integrate curricula using a community-based client, ultimately leading to scholarship and professional outcomes. Specifically, this study analyzes the launch of a service learning-based smoking cessation campaign on a Midwest college campus.
Selling Truth: How Nike’S Advertising To Women Claimed A Contested Reality, Jean Grow, Joyce Wolburg
Selling Truth: How Nike’S Advertising To Women Claimed A Contested Reality, Jean Grow, Joyce Wolburg
Jean Grow
This study tracked the evolution of three “big ideas” in Nike’s advertising to women from 1990 to 2000: empowerment, entitlement, and product emphasis. It also takes a longitudinal look at the process from which the ads were created and the way the creative team addressed the constraints upon that process. Based on depth interviews among key informants at Nike and its two ad agencies during that decade, it is the story of how the creative team produced advertising that challenged the media norms that affect the roles of women associated with the institution of sports. Though their creative strategy was …
Savedisney.Com And Activist Challenges: A Habermasian Perspective On Corporate Legitimacy, Sarah Feldner, Rebecca Meisenbach
Savedisney.Com And Activist Challenges: A Habermasian Perspective On Corporate Legitimacy, Sarah Feldner, Rebecca Meisenbach
Sarah Feldner
This study develops a Habermasian framework for evaluating and generating challenges to organizational legitimacy. The launch of the SaveDisney.com web site represents an innovative example of an Internet-based activist public successfully challenging a corporation’s legitimacy and advocating for changes in corporate governance. Legitimacy research has focused on strategies used by organizations to build legitimacy (e.g., Dowling & Pfeffer, 1975; Metzler, 2001), but scholars rarely address how publics challenge legitimacy claims. Using Habermas’ conceptualization of communicative action and legitimacy to explore the SaveDisney.com case offers insight into ways that activist publics successfully challenge and reject the legitimacy claims of powerful corporations.
Reconsidering Public Relations’ Infatuation With Dialogue: Why Engagement And Reconciliation Can Be More Ethical Than Symmetry And Reciprocity, Kevin Stoker, Kati Berg
Reconsidering Public Relations’ Infatuation With Dialogue: Why Engagement And Reconciliation Can Be More Ethical Than Symmetry And Reciprocity, Kevin Stoker, Kati Berg
Kati Berg
Advocates of dialogic communication have promoted two-way symmetrical communication as the most effective and ethical model for public relations. This article uses John Durham Peters’s critique of dialogic communication to reconsider this infatuation with dialogue. In this article, we argue that dialogue’s potential for selectivity and tyranny poses moral problems for public relations. Dialogue’s emphasis on reciprocal communication also saddles public relations with ethically questionable quid pro quo relationships. We contend that dissemination can be more just than dialogue because it demands more integrity of the source and recognizes the freedom and individuality of the source. The type of communication, …
Transparency In Communication: An Examination Of Communication Journals’ Conflicts-Of-Interest Policies, Lawrence Soley, Sarah Feldner
Transparency In Communication: An Examination Of Communication Journals’ Conflicts-Of-Interest Policies, Lawrence Soley, Sarah Feldner
Lawrence Soley
Increased corporate-sponsored university research and professorial consulting has caused medical, psychological, and other scientific journals to adopt conflicts-of-interest disclosure policies. This study examines editorial policies concerning conflicts of interest at communication journals in the context of Habermas’s theory of communicative action. The results show that communication journals do not have the same mandatory disclosure requirements that journals of other disciplines have. In this regard, communication research journals are similar to the mass media. Consequently, the article suggests that disclosure policies are needed if communication research journals are to function as part of a larger dialogic process. Moreover, communication researchers are …
Connected To The Organization: A Survey Of Communication Technologies In The Modern Organizational Landscape, Scott D'Urso, Kristen Pierce
Connected To The Organization: A Survey Of Communication Technologies In The Modern Organizational Landscape, Scott D'Urso, Kristen Pierce
Scott D'Urso
In today’s organizations, traditional and cutting-edge technologies compete for increased usage. This exploratory project provides a snapshot of the communication technology (CT) landscape by examining the use of 25 different CTs and their relations to a variety of common demographic variables. Results suggest that, although newer CTs are in use today, more traditional and established CTs such as e-mail, Internet, telephones, and voicemail still dominate the landscape.
Basking Behavior Of Emydid Turtles (Chysemys Picta Marginata, Graptemys Geographica, And Trachemys Scripta Elegans) In An Urban Landscape, W. Peterman, Travis Ryan
Basking Behavior Of Emydid Turtles (Chysemys Picta Marginata, Graptemys Geographica, And Trachemys Scripta Elegans) In An Urban Landscape, W. Peterman, Travis Ryan
Travis J. Ryan
Basking is common in emydid turtles and is generally accepted to be in thermoregulatory behavior. In 2004, we quantified and described the basking behavior of turtles in the Central Canal of Indianapolis. This canal system runs through an urban landscape that is dominated by fragmented woodlots, residential areas. and commercial areas. We observed that basking turtles exhibited variable basking behavior. with spatial and temporal shins in basking behavior from east-facing banks in the morning to west-facing banks in the afternoon. Turtles in the Central Canal are subject to frequent disturbance, which altered basking behavior. Many turtles forewent aerial basking on …

X-ray fiber diffraction data were obtained and helical pitch and symmetry were determined for seven members of the family Potyviridae, including representatives from the genera Potyvirus, Rymovirus, and Tritimovirus. The diffraction patterns are similar, as expected. There are, however, significant variations in the symmetries, as previously found among the flexible potexviruses, but not among the rigid tobamoviruses. Wheat streak mosaic virus, the only member of the genus Tritimovirus examined, displayed the largest deviations in diffraction data and helical parameters from the other viruses in the group.
