Jeff Koons: In His Space

Space, a major visual element, can be examined in depth in Jeff Koons’s artwork. Koons produces art in different series and each series contains numerous pieces. The appendages of the mechanical devices, a major element of space in the early series, accentuate the sexuality present in Koons’s art, as well as the surface quality and materials used in all the series. Koons’s obsession with perfection is what generates the flawless exteriors making the surface material void of human touch and elevating the sometimes kitsch subjects of the pieces. Koons uses stainless steel, a relatively inexpensive material associated with manufactured goods commonly used by everyone. This combination of commonly found material for the low-brow subject matter on one side, and the artist’s obsession with the surface’s perfection on the other side, represents a major challenge to traditional sculpture. Traditional sculpture commonly uses expensive materials, such as bronze or marble, to represent allegorical subject matter, mainly addressing the upper classes. Through this strategy, Koons elevates kitsch into high art. The series examined include: Pre New, The New, Equilibrium, Luxury, and Degradation, Statuary, Kiepenkerl, Banality, Made in Heaven, and Celebration

Facilitating Access to Digital Records of Practice in Education with Technology

Many disciplines are changing their traditional approaches to data, encouraging data producers to share data and enable researchers and practitioners to reuse data to answer new research questions and address educational needs. In response, data repositories have emerged, and the availability of data has increased. Repositories build infrastructure to facilitate data access and provide software tools for reuse. This paper analyzes the reuse of digital records of practice (DROP) in education through the lens of one software tool, Zaption, focusing on DROP reuse by teachers, teacher educators, and individuals involved in professional development activities. Using analytics data from one repository’s Zaption integration from 2012-2016, we found that producers and reusers of DROP preferred an array of rich communication tools over tools that added technical functionalities. The results contribute both to our knowledge of DROP reusers as well as inform repositories about software choices to facilitate reuse.Institute of Museum and Library Services (LG-06-14-0122-14)Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/147456/1/ELearn_2018_proceedings_FINAL_Deepblue.pd

Video Re-Use in Mathematics Teacher Education

This study examines the re-use of existing video records of practice (VRPs) in preservice mathematics teacher education. The research is based on 34 interviews with mathematics teacher educators from 24 different institutions across the United States and three other countries, who are re-using VRPs from online repositories, books with accompanying videos, and other online and offline sources. In this paper, we report on three different types of VRP re-use raised by our interview participants. We discuss the instructional goals they described as well as the learning activities in which the VRPs were used. This paper addresses the question, how do mathematics teacher educators make use of existing VRPs to support the professional learning of preservice teachers? The paper concludes with a discussion of what these findings mean for teacher educators who re-use VRPs as well as for those who produce VRPs that can be re-used in preservice teacher education.Institute of Museum and Library Services (LG-06-14-0122-14)Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/144779/1/Suzuka_etal_2018_SITE_DeepBlueA.pdfDescription of Suzuka_etal_2018_SITE_DeepBlueA.pdf : Main Articl

Physicians\u27 Perceptions of Quality of Care, Professional Autonomy, and Job Satisfaction in Canada, Norway, and the United States

Background We lack national and cross-national studies of physicians’ perceptions of quality of patient care, professional autonomy, and job satisfaction to inform clinicians and policymakers. This study aims to compare such perceptions in Canada, the United States (U.S.), and Norway. Methods We analyzed data from large, nationwide, representative samples of physicians in Canada (n = 3,213), the U.S. (n = 6,628), and Norway (n = 657), examining demographics, job satisfaction, and professional autonomy. Results Among U.S. physicians, 79% strongly agreed/agreed they could provide high quality patient care vs. only 46% of Canadian and 59% of Norwegian physicians. U.S. physicians also perceived more clinical autonomy and time with their patients, with differences remaining significant even after controlling for age, gender, and clinical hours. Women reported less adequate time, clinical freedom, and ability to provide high-quality care. Country differences were the strongest predictors for the professional autonomy variables. In all three countries, physicians’ perceptions of quality of care, clinical freedom, and time with patients influenced their overall job satisfaction. Fewer U.S. physicians reported their overall job satisfaction to be at-least-somewhat satisfied than did Norwegian and Canadian physicians. Conclusions U.S. physicians perceived higher quality of patient care and greater professional autonomy, but somewhat lower job satisfaction than their colleagues in Norway and Canada. Differences in health care system financing and delivery might help explain this difference; Canada and Norway have more publicly-financed, not-for-profit health care delivery systems, vs. a more-privately-financed and profit-driven system in the U.S. None of these three highly-resourced countries, however, seem to have achieved an ideal health care system from the perspective of their physicians

Reorienting MHD colliding flows: a shock physics mechanism for generating filaments normal to magnetic fields

We present numerical simulations of reorienting oblique shocks that form in the collision layer between magnetized colliding flows. Reorientation aligns post-shock filaments normal to the background magnetic field. We find that reorientation begins with pressure gradients between the collision region and the ambient medium. This drives a lateral expansion of post-shock gas, which reorients the growing filament from the outside-in (i.e. from the flow/ambient boundary, towards the colliding flows axis). The final structures of our simulations resemble polarization observations of filaments in Taurus and Serpens South, as well as the integral-shaped filament in Orion A. Given the ubiquity of colliding flows in the interstellar medium, shock reorientation may be relevant to the formation of filaments normal to magnetic fields
