Judging a book by its cover: interface elements that affect reader selection of ebooks
Digital library research has demonstrated the impact of content presentation on both search and reading behaviours. In this paper, we scrutinise the influence of ebook presentation on user behaviour, focussing on document thumbnails and the first page view. We demonstrate that flaws in presentation increase the volume of short time-span reading, and reduce the likelihood of long-span reading when compared to other documents. This reflects other patterns of information seeking behaviour that demonstrate increased short-term reading when information content is uncertain, and suggests an ineffective use of reader time on less useful content
How to take a book off the shelf: Learning about ebooks from using a physical library
Little is known about how people select ebooks or books. This paper reports initial results of a study in which we observe patrons of two libraries when selecting books. From the results of the study we aim to gain insights into book selection strategies, which may be used to support ebook selection and purchasing
Book selection behavior in the physical library: implications for ebook collections
Little is known about how readers select books, whether they be print books or ebooks. In this paper we present a study of how people select physical books from academic library shelves. We use the insights gained into book selection behavior to make suggestions for the design of ebook-based digital libraries in order to better facilitate book selection behavior
Carbon Monoxide Observations Toward Star Forming Regions in the Outer Scutum-Centaurus Spiral Arm
The Outer Scutum-Centaurus arm (OSC) is the most distant molecular spiral arm
known in the Milky Way. The OSC may be the very distant end of the well-known
Scutum-Centaurus arm, which stretches from the end of the Galactic bar to the
outer Galaxy. At this distance the OSC is seen in the first Galactic quadrant.
The population of star formation tracers in the OSC remains largely
uncharacterized. Extragalactic studies show a strong correlation between
molecular gas and star formation, and carbon monoxide (CO) emission was
recently discovered in the OSC. Here we use the Arizona Radio Observatory (ARO)
12-m telescope to observe the CO J = 1-0 and CO J = 1-0
transitions toward 78 HII region candidates chosen from the WISE Catalog of
Galactic HII Regions. These targets are spatially coincident with the Galactic
longitude-latitude () OSC locus as defined by HI emission. We detect
CO emission in % of our targets. In total, we detect 117 CO and
40 CO emission lines. About 2/3 of our targets have at least one
emission line originating beyond the Solar orbit. Most of the detections beyond
the Solar orbit are associated with the Outer Arm, but there are 17 CO
emission lines and 8 CO emission lines with LSR velocities that are
consistent with the velocities of the OSC. There is no apparent difference
between the physical properties (e.g., molecular column density) of these OSC
molecular clouds and non--OSC molecular clouds within our sample.Comment: 16 pages, 8 figures, 3 tables, accepted for publication in Ap
Guest Editorial Special Issue on Medical Imaging and Image Computing in Computational Physiology
International audienceThe January 2013 Special Issue of IEEE transactions on medical imaging discusses papers on medical imaging and image computing in computational physiology. Aslanid and co-researchers present an experimental technique based on stained micro computed tomography (CT) images to construct very detailed atrial models of the canine heart. The paper by Sebastian proposes a model of the cardiac conduction system (CCS) based on structural information derived from stained calf tissue. Ho, Mithraratne and Hunter present a numerical simulation of detailed cerebral venous flow. The third category of papers deals with computational methods for simulating medical imagery and incorporate knowledge of imaging physics and physiology/biophysics. The work by Morales showed how the combination of device modeling and virtual deployment, in addition to patient-specific image-based anatomical modeling, can help to carry out patient-specific treatment plans and assess alternative therapeutic strategies
DeepGauge: Multi-Granularity Testing Criteria for Deep Learning Systems
Deep learning (DL) defines a new data-driven programming paradigm that
constructs the internal system logic of a crafted neuron network through a set
of training data. We have seen wide adoption of DL in many safety-critical
scenarios. However, a plethora of studies have shown that the state-of-the-art
DL systems suffer from various vulnerabilities which can lead to severe
consequences when applied to real-world applications. Currently, the testing
adequacy of a DL system is usually measured by the accuracy of test data.
Considering the limitation of accessible high quality test data, good accuracy
performance on test data can hardly provide confidence to the testing adequacy
and generality of DL systems. Unlike traditional software systems that have
clear and controllable logic and functionality, the lack of interpretability in
a DL system makes system analysis and defect detection difficult, which could
potentially hinder its real-world deployment. In this paper, we propose
DeepGauge, a set of multi-granularity testing criteria for DL systems, which
aims at rendering a multi-faceted portrayal of the testbed. The in-depth
evaluation of our proposed testing criteria is demonstrated on two well-known
datasets, five DL systems, and with four state-of-the-art adversarial attack
techniques against DL. The potential usefulness of DeepGauge sheds light on the
construction of more generic and robust DL systems.Comment: The 33rd IEEE/ACM International Conference on Automated Software

Analysis of CARD14 Polymorphisms in Pityriasis Rubra Pilaris: Activation of NF-κB.
Pityriasis rubra pilaris (PRP) is a rare inflammatory papulo-squamous disorder manifesting with palmoplantar keratoderma and follicular hyperkeratotic papules which tend to coalesce into large, scaly, erythematous plaques often progressing to exfoliative erythroderma (Klein et al., 2010; Petrof et al., 2013). PRP is often misdiagnosed as psoriasis, a more common papulo-squamous inflammatory disorder. Nevertheless, the two conditions, in their classic presentations, are clearly distinct, and can be distinguished by clinical findings and histopathologic features (Magro and Crowson, 1997). Clinically, PRP manifests with characteristic “sparing islands ” of apparently normal skin, palmoplantar keratoderma and follicular papules. The disease is frequently self-limiting within a few years ’ timeframe. Histopathology of PRP is characterized by alternating ortho- and parakeratosis rete ridges oriented in vertical and horizontal arrays (“checkerboard pattern”), acanthosis with broadened bases, follicular plugging, perivascular lymphocytic infiltrate in the dermis, and lack of neutrophils in the epidermis. Currently, there is no specific or uniformly effective treatment for PRP. Most cases of PRP are sporadic and without family history, but a familial form with an autosomal dominant inheritance with partial penetrance represents <6 % of al
Population dynamics of rhesus macaques and associated foamy virus in Bangladesh.
Foamy viruses are complex retroviruses that have been shown to be transmitted from nonhuman primates to humans. In Bangladesh, infection with simian foamy virus (SFV) is ubiquitous among rhesus macaques, which come into contact with humans in diverse locations and contexts throughout the country. We analyzed microsatellite DNA from 126 macaques at six sites in Bangladesh in order to characterize geographic patterns of macaque population structure. We also included in this study 38 macaques owned by nomadic people who train them to perform for audiences. PCR was used to analyze a portion of the proviral gag gene from all SFV-positive macaques, and multiple clones were sequenced. Phylogenetic analysis was used to infer long-term patterns of viral transmission. Analyses of SFV gag gene sequences indicated that macaque populations from different areas harbor genetically distinct strains of SFV, suggesting that geographic features such as forest cover play a role in determining the dispersal of macaques and SFV. We also found evidence suggesting that humans traveling the region with performing macaques likely play a role in the translocation of macaques and SFV. Our studies found that individual animals can harbor more than one strain of SFV and that presence of more than one SFV strain is more common among older animals. Some macaques are infected with SFV that appears to be recombinant. These findings paint a more detailed picture of how geographic and sociocultural factors influence the spectrum of simian-borne retroviruses
An African-American Resources and Needs Assessment of the West Bloomington Area, Phase 1
Over the course of the Fall 2009 semester, students in the Community Project Design and Management class worked with members of West Bloomington to recognize the growing needs within the community. Along with the African-American Focus Workgroup (AAFW) and the West Bloomington Revitalization Partnership (WBRP), the students completed Phase 1 of an African-American resources and needs assessment resulting in this report. This document reflects needs, wants, and hopes of the West Bloomington community and the AAFW. Comprehensively, this document is meant to serve as a bridge between community members and AAFW members.
As Bloomington as a whole continues to grow and expand, some members within the community feel the difficulty of being left out of development. Therefore, the project‟s purpose was to help ascertain the assets and deficiencies within the West Bloomington neighborhood with the participation of community members, and to help the AAFW integrate their goals with those of the WBRP. This report can aid future efforts and provide useful information in the development of the West Bloomington area.
The report includes a brief review of the literature considering race, education, income, age, public space, housing, civil society, and community-based participatory research. The report also includes sections outlining the research methods used, the research findings along the same themes used in the literature review, a discussion of limitations and barriers to research, and conclusions and recommendations.
Appendices include Institutional Review Board (IRB) protocol for ethical treatment and protection of research participants, definition of the study area for drawing out Census data, and a Survey Design and Administration Protocol Handbook to aid in administering surveys drafted for AAFW member organizations to use with their staff and volunteers, patrons, and the general public.
Student researchers analyzed public data and local reports to understand the background and demographics of the West Bloomington community. Reports consulted include these topics: housing conditions and issues; food justice; Census data on race, income, and age; community and economic development; and education statistics for District 87 and West Bloomington schools.
Through various focus groups, four common themes appeared: the need for greater communication between and among local organizations and community members; the need for additional activities, especially for young people; a lack of accessibility to various services offered by (or in) the City of Bloomington and surrounding areas; and distressed amenities. Communication can be strengthened between the WBRP and the AAFW, between West Bloomington community members and the City of Bloomington, and among all of these groups and members.
Focus group findings also show that the West Bloomington community and organizations serving it do not offer activities to people of all age ranges. In addition, all focus groups shared comments about transportation issues within West Bloomington. Regarding distressed amenities, focus group participants brought up issues concerning poor housing conditions, inadequate amenities at local parks, and old infrastructure in need of repair or replacement.
Findings from key informant interviews also acknowledged several areas for enhancement within the West Bloomington community. Within the community, apathy and a lack of respect among residents were identified as negative attributes coupled with a perceived lack of police presence in the area. Residents linked these attributes to a fear of crime, and specifically, drug dealing, prostitution, and gang activity and recruitment. Resource collaboration and greater awareness of available resources also are viewed as necessary enhancements within the community and those serving it.
West Bloomington residents serving as key informant interviewees identified issues of homelessness, overcrowded housing facilities, and a lack of affordable housing. Some interviewees expressed a desire for better notification of neighborhood events. Several interviewees mentioned a desire for better communication between the City of Bloomington and West Bloomington community and a better working relationship with the police department. Additionally, multiple interviewees discussed the importance of education, including the need for more job training and literacy programs.
This report includes conclusions and recommendations based on findings from key informant interviews, focus groups, local and public data review, and past and future surveys. These recommendations are broken down into three categories focusing on the City of Bloomington, the West Bloomington neighborhood, and youth.
City-related recommendations include the following: The Bloomington Police Department can increase its visible presence in the West Bloomington neighborhood by providing foot patrol. The City of Bloomington should develop a plan for addressing infrastructure needs in the West Bloomington area. The Bloomington-Normal Public Transit System can evaluate the current mass transit bus routes for West Bloomington. Improved civic awareness and education can increase residents‟ skills and abilities to address grievances and development issues within their community.
Neighborhood recommendations advise the following: Primarily, communication among all stakeholders needs to be improved. Stakeholders can increase awareness of available services, programs, and resources that can benefit community members. A community fair can be held within the West Bloomington neighborhood. A feasibility study should be performed for a multi-purpose community center to be located in the West Bloomington neighborhood.
The youth recommendations suggest the following: Encourage The Bloomington Boys and Girls Club to determine if additional services could be added to benefit the teen youth of West Bloomington. Increase the availability of summer programs to benefit both working parents and children. Explore effective strategies for identifying and dealing with barriers to development, especially those that apply to youth and crime. Stakeholders can collaborate on a campaign to bring awareness and encourage action around the need for more volunteer mentors, especially male mentors who are needed for West Bloomington male youth.
In conclusion, this report sheds some light on the needs, wants, assets, and resources of the West Bloomington community. It is our hope that this report will serve as an impetus for enhanced relationships among the AAFW, the WBRP, West Bloomington residents, and the City of Bloomington, as well as provide information and materials to aid in future development
