The Data Science Opportunity: Crafting a Holistic Strategy

The rise of data-driven research and discovery may be one of the greatest strategic opportunities to confront academic libraries in a generation. The argument advanced in this article is that the data science opportunity is about data curation AND data analysis. Thus the development of a holistic data science strategy ought to include both elements. Up until now, academic libraries have largely responded to the data science opportunity from a curatorial and archiving perspective. However, this is beginning to change. The case for crafting a holistic data science strategy is presented in six parts in this article. In part one, a broad overview of the data science opportunity is presented, followed by a definition of data analysis and data curation in part two. The traditional academic library response (curation) and a reframing of it to include data analysis are then presented in two separate parts. And finally, part five reports findings from a recent survey conducted at the University of Florida (UF) which indicates robust demand for training in analytical tools and technologies. The article concludes with some thoughts on the challenges of offering data analysis services, using the UF experience to highlight key issues.     

Extending Learning Communities: New Technologies,Multiple Literacies,and Culture Blind Pedagogies

Technologies such as videoconferencing used for distance education are creating ways for high schools to extend their learning communities to connect youth with professional communities of practice in ways that approximate the face-to-face interactions in traditional classrooms. These technologies are often touted as a way to augment course offerings and curricula, particularly those needed for college-going. The use of videoconferencing technologies alone, however, does not ensure that the desired forms of interaction will occur particularly given their reliance on traditional banking-model pedagogies and literacies. In this article, we focus on college bound Black and Latino/a youth from under resourced urban communities and their negotiations of new technologies, multiple literacies, and traditional pedagogies within a music education learning community extended through videoconferencing technologies. Employing a multicultural feminist critical theoretical framework, we unearth the ways Black and Latino/a youths identities as active learners and college-bound musicians shape, and are shaped, in the interplay of new technologies, multiple literacies, and traditional pedagogies within a music education classroom.     

Developing inclusive educators: enhancing the accessibility of teaching and learning in higher education

In light of the growing population of students with disabilities at colleges and universities worldwide, faculty development connected to accessible teaching is of paramount importance. Drawing from the existing literature and from the results of a qualitative study of educational accessibility at one Canadian university, this article offers a series of recommendations for academic developers hoping to establish effective development initiatives focused on accessible teaching and learning. Key issues considered include the need to support instructors in translating principles of inclusive teaching into practice, the value of discussion-based approaches that take up difficult questions about minimum standards, and the question of whether development initiatives should be discipline-specific or interdisciplinary, mandatory or optional. Recommendations for further research are also discussed.     

Morning-to-afternoon increases in cortisol concentrations for infants and toddlers at child care: age differences and behavioral correlates

This study examined salivary cortisol, a stress-sensitive hypothalamic-pituitary-adrenocortical (HPA) axis hormone in 20 infants (12 females; M age = 10.8 months) and 35 toddlers (20 females; M age = 29.7 months) in full-day, center-based child care. Samples were taken at approximately 10:00 a.m. and 4:00 p.m. at child care and at home. At child care, 35% of infants and 71% of toddlers showed a rise in cortisol across the day; at home, 71% of infants and 64% of toddlers showed decreases. Toddlers who played more with peers exhibited lower cortisol. Controlling age, teacher-reported social fearfulness predicted higher afternoon cortisol and larger cortisol increases across the day at child care. This phenomenon may indicate context-specific activation of the HPA axis early in life.     

Mathematics engagement in an Australian lower secondary school

The importance of actively engaging in mathematics discourse in order to learn mathematics is well recognized. In this paper, I use Basil Bernstein’s concepts of pedagogic discourse to document and analyse academic learning time of students in Years 8 and 9 at a suburban lower secondary school: in particular, for what proportion of class time students reported being academically engaged, their explanations for this engagement and how they felt about the discourse. It was found that many students had disengaged from mathematical endeavour as a result of the failure of the instructional discourse either to engage students or to serve the purpose of developing discipline-specific content knowledge. The reasons for this relate to the overemphasis on mundane mathematics resulting in some students lacking the cognitive tools to engage with the concepts and having neither the intrinsic nor instrumental motivation to persist with secondary school esoteric mathematics. The implications for mathematics curriculum development are discussed.     

Are There Separate Neural Systems for Spelling? New Insights into the Role of Rules and Memory in Spelling from Functional Magnetic Resonance Imaging

ABSTRACT— How do people spell the thousands of words at the tips of their tongues? Are words with regular sound‐to‐letter correspondences (e.g., “blink”) spelled using the same neural systems as those with irregular correspondences (e.g., “yacht”)? By offering novel neuroimaging evidence, we aim to advance contemporary debate about whether people use a single lexical memory process or whether dual mechanisms of lexical memory and sublexical phonological rules work in concert. We further aim to advance understanding of how people read by taking a fresh look at the related yet distinct capacity to spell. During functional magnetic resonance imaging scanning, 12 participants heard low‐frequency regular words, irregular words, and nonwords (e.g., “shelm”) and responded whether a visual presentation of the word was spelled correctly or incorrectly. While behavioral measures suggested some differences in accuracy and reaction time for the different word types, the neuroimaging results alone demonstrated robust differential processing and support a dual‐route model of spelling, with implications for how spelling is taught and remediated in clinical and educational contexts.     

Effect of nutritional supplements and protease inhibitor on the yield of es antigens ofBrugia malayi microfilariaein vitro

Brugia malayi microfilarial excretory-secretory (mf ES) antigens obtained byin vitro maintenance of mf are important tools in the immunodiagnosis of bancroftian filariasis. To increase the yield of mf ES products, the effect of nutritional supplements on the culture medium (RPMI 1640) and the maintenance temperature were studied. Supplementation of RPMI 1640 medium with organic acids and sugars of Grace's insect culture medium forin vitro maintenance of 10 lakhs of mf in 40 ml medium increased the yield of mf ES antigen from 152 μg to 364 μg of mean protein, content and the mean antigen titre from 200 to 400. Supplementation with phenyl methyl sulphonyl fluoride (PMSF) and shift in the culture temperature resulted in a further increase in the yield of mf ES antigen to 502 μg of mean total protein with an antigen titre of 800. The modification resulted in a net increase of 3 fold in the protein content and 4 fold in the antigen titre of ES products. The above modifications in thein vitro maintenance of mf did not affect the diagnostic quality of mf ES antigen, which gave a sensitivity and specificity of 80% and 90% respectively in detection of filarial IgG antibodies inWuchereria bancrofti infected cases.     

Migrating facsimiles: When copies disappear from conservation control

A 2014 exhibition of Meriç Algün Ringborg at Moderna Museet, Stockholm, Sweden, exploring identity and belonging involved the making of facsimiles. The installation included a sound work, booklets to be taken, and a book to be read. Exhibition copies were created of personal letters for open display which were not to be touched. Contrary to the artist's wishes, the work was constantly handled. Made for this one installation, the facsimiles transcended the exhibition and were returned with the work to the artist. The paper examines issues of authenticity and control from a conservation standpoint, and details discussions surrounding reproduction in contemporary art museum conservation practice.
