Visualizing Scholarship as Social Change

This visualization and accompanying short essay articulates both a broad definition of what constitutes “scholarship as social change,” any knowledge production that has a goal of exploring, articulating, and intervening in inequities and injustices, past and present, as well as projects that helped inspire the contributions of to the Curated Futures project (Gamifying Digital Collections, Remaking Space and Place, FLAME, and The Third Library and the Commons). It also invites readers to submit their own examples of projects that they think embody “scholarship as social change”

When Text Isn’t Enough: An Exploration into the World of Multimodal Scholarship in the Digital Arts, Sciences and Humanities

Increasingly, scholars are producing works in non-traditional genres and mediums, published using alternative platforms. This presentation will describe some of the trends and unique affordances of multimodal scholarship across the digital arts, sciences and humanities domains. Examples discussed include results from a recent bibliometric study on science video abstracts; Humanities dissertations, monographs, and edited collections published, and sometimes collaboratively written, online; and digital art scholarship, such as the Words of Encouragement installation (Weisman Art Museum). Finally, we will discuss the potential implications of these emerging areas of scholarship on librarians and library services

3D Scanning in the Library!

Experimenting with new uses of technologies can be a great way to engage library users. We will teach workshop participants how to use an Xbox Kinect, the motion sensing device that allows for gesture control, and Skanect software to create 3D scans of participants. Users can manipulate their scan files in any way they choose, including creating a 3D print of it. In demonstrating how to use this technology, we will show how the activity can be done using a basic swivel chair to make “busts” of participants or, for the especially adventurous, building your own motorized rotating platform for full body scans. Finally, we will share our workflow that we applied to multiple events, including a city-wide art festival and multiple Libraries’ events. This activity allows participants to explore gaming technology in interactive and new ways and hopefully inspire participants to try this at their own institutions

Genomic and Metabolic Studies of the Impact of Probiotics on a Model Gut Symbiont and Host

Probiotics are deliberately ingested preparations of live bacterial species that confer health benefits on the host. Many of these species are associated with the fermentation of dairy products. Despite their increasing use, the molecular details of the impact of various probiotic preparations on resident members of the gut microbiota and the host are generally lacking. To address this issue, we colonized germ-free mice with Bacteroides thetaiotaomicron, a prominent component of the adult human gut microbiota, and Bifidobacterium longum, a minor member but a commonly used probiotic. Simultaneous whole genome transcriptional profiling of both bacterial species in their gut habitat and of the intestinal epithelium, combined with mass-spectrometric analysis of habitat-associated carbohydrates, revealed that the presence of B. longum elicits an expansion in the diversity of polysaccharides targeted for degradation by B. thetaiotaomicron (e.g., mannose- and xylose-containing glycans), and induces host genes involved in innate immunity. Although the overall transcriptome expressed by B. thetaiotaomicron when it encounters B. longum in the cecum is dependent upon the genetic background of the mouse (as assessed by a mixed analysis of variance [ANOVA] model of co-colonization experiments performed in NMRI and C57BL/6J animals), B. thetaiotaomicron's expanded capacity to utilize polysaccharides occurs independently of host genotype, and is also observed with a fermented dairy product-associated strain, Lactobacillus casei. This gnotobiotic mouse model provides a controlled case study of how a resident symbiont and a probiotic species adapt their substrate utilization in response to one another, and illustrates both the generality and specificity of the relationship between a host, a component of its microbiota, and intentionally consumed microbial species

Real-Time Measurement of F-Actin Remodelling during Exocytosis Using Lifeact-EGFP Transgenic Animals

F-actin remodelling is essential for a wide variety of cell processes. It is important in exocytosis, where F-actin coats fusing exocytic granules. The purpose of these F-actin coats is unknown. They may be important in stabilizing the fused granules, they may play a contractile role and promote expulsion of granule content and finally may be important in endocytosis. To elucidate these functions of F-actin remodelling requires a reliable method to visualize F-actin dynamics in living cells. The recent development of Lifeact-EGFP transgenic animals offers such an opportunity. Here, we studied the characteristics of exocytosis in pancreatic acinar cells obtained from the Lifeact-EGFP transgenic mice. We show that the time-course of agonist-evoked exocytic events and the kinetics of each single exocytic event are the same for wild type and Lifeact-EGFP transgenic animals. We conclude that Lifeact-EGFP animals are a good model to study of exocytosis and reveal that F-actin coating is dependent on the de novo synthesis of F-actin and that development of actin polymerization occurs simultaneously in all regions of the granule. Our insights using the Lifeact-EGFP mice demonstrate that F-actin coating occurs after granule fusion and is a granule-wide event

A randomized phase II efficacy and correlative studies of cetuximab with or without sorafenib in recurrent and/or metastatic head and neck squamous cell carcinoma

A combination of cetuximab and sorafenib in patients with recurrent and/or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) were assessed for potential benefit

Trends in Utilization of Adrenalectomy in the United States: Have Indications Changed?

Minimally invasive approaches have dramatically reduced morbidity associated with adrenalectomy. There has been concern that an increased frequency of adrenal imaging along with the advantages of less morbidity could influence the indications for adrenalectomy. We tested the hypothesis that adrenalectomy has become more common over time and that benign diseases have been increasingly represented among procedural indications. The Nationwide Inpatient Sample (NIS) database was utilized to determine the incidence of adrenalectomy and the associated surgical indications in the United States between 1988 and 2000. All discharged patients were identified whose primary ICD-9-CM procedure code was for adrenalectomy, regardless of the specific surgical approach (laparoscopic adrenalectomy was not reliably coded). This subset was then queried for associated ICD-9-CM diagnostic codes. Linear regression and t -tests were utilized to determine the significance of trends. The total number of adrenalectomies increased significantly, from 12.9 per 100,000 discharges in 1988 to 18.5 per 100,000 discharges in 2000 ( p = 0.000003). The total number of adrenalectomies with a primary ICD-9-CM code for malignant adrenal neoplasm did not increase significantly: from 1.2 per 100,000 discharges in 1988 to 1.6 per 100,000 discharges in 2000 ( p = 0.47). The total number of adrenalectomies with a primary ICD-9-CM diagnostic code for benign adrenal neoplasm increased significantly, from 2.8 per 100,000 discharges in 1988 to 4.8 per 100,000 discharges in 2000 ( p = 0.00002). The average percentage of adrenalectomies performed for malignant neoplasm was significantly higher during the period 1988–1993 when compared to 1994–2000 (11% vs. 9%; p = 0.002). The average percentage of adrenalectomies performed for benign neoplasm was significantly lower during 1988–1993 when compared to 1994–2000 (25% vs. 28%; p = 0.015). Adrenalectomy is being performed with increasing frequency. This is associated with an increase in the proportion of adrenalectomies performed for benign neoplasms. Assuming no significant change in disease prevalence during the study period, these data suggest that indications for adrenalectomy may have changed somewhat over that period.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/41300/1/268_2004_Article_7619.pd
