Automated SKOS Vocabulary Design for the Biopharmaceutical Industry

Ensuring quick and consistent access to large collections of unstructured documents is one of the biggest challenges facing knowledge-intensive organizations. Designing specific vocabularies to index and retrieve documents is often deemed too expensive, full-text search being preferred despite its known limitations. However, the process of creating controlled vocabularies can be partly automated thanks to natural language processing and machine learning techniques. With a case study from the biopharmaceutical industry, we demonstrate how small organizations can use an automated workflow in order to create a controlled vocabulary to index unstructured documents in a semantically meaningful way.     

Training for the Unthinkable: Examining Message Characteristics on Motivations to Engage in an Active-Shooter Response Video

Campus safety is becoming an increasing concern for academic institutions due to numerous recent tragedies. To prepare students, staff, and faculty for these events, schools are beginning to use active shooter response training videos such as Run, Hide, Fight—a 5-minute video created by the U.S. Department of Homeland Security. Framed in protection motivation theory, this study employs a 3 x 2 factorial design to test the influence of message medium (email, text, or tweet) and frame (direct or fear-based message) on students' completion of the safety training video. The findings suggest that the combination of message frame and message medium influence training completion. Additionally, the video itself led to a significant increase in participants’ self-efficacy, safety knowledge, and campus safety salience.     

Investment in early American art: the impact of transaction costs and no-sales on returns

Art, along with other “treasure assets,” has become a central object for investment opportunities. Investment return studies using hedonic and resale price regressions on different artistic periods and styles produce estimates of varying rates of return, predominately low rates with high standard deviations. The present study employs a new sample of American art sold at auction between 1987 and 2011—art created before 1950 by 33 artists born prior to 1900. Our study, unlike those that preceded it, considers works that are no-sales (those “bought-in” for failing to sell at auction at or above a predetermined and negotiated minimum price), in addition to full transaction costs—buyers and sellers premia on hammer prices. We conclude that investment return calculations are biased upward and may be negative when these factors are considered and that the “consumption utility” of art may be higher than previously thought. However, using a variant of the capital asset pricing model, we find that investment in early American art may still be desirable in a diversified portfolio of assets for when the price of stock assets falls, the price of art does not fall in the same proportion.     

Sixth-grade students’ engagement in academic tasks

Student engagement is important for teachers and researchers because it is associated with student achievement. Guided by self-determination theory, this year-long case study used observations and interviews to examine six students’ behavioral, affective, and cognitive engagement in integrated literacy and social studies tasks. Task differences were rated according to the degree to which tasks were authentic, collaborative, challenging, student directed, and sustained. Results demonstrated that, overall, students were more engaged in tasks that include a higher degree of these elements. In particular, students reported that they were engaged in tasks that included collaboration, new learning, and teacher support.     

Longitudinal Trajectories of Family Functioning Among Recent Immigrant Adolescents and Parents: Links With Adolescent and Parent Cultural Stress,Emotional Well-Being,and Behavioral Health

This study examined longitudinal effects of adolescent and parent cultural stress on adolescent and parent emotional well-being and health behaviors via trajectories of adolescent and parent family functioning. Recent immigrant Latino adolescents (M_age = 14.51) and parents (M_age = 41.09; N = 302) completed measures of these constructs. Latent growth modeling indicated that adolescent and parent family functioning remained stable over time. Early levels of family functioning predicted adolescent and parent outcomes. Baseline adolescent cultural stress predicted lower positive adolescent and parent family functioning. Latent class growth analyses produced a two-class solution for family functioning. Adolescents and parents in the low family functioning class reported low family functioning over time. Adolescents and parents in the high family functioning class experienced increases in family functioning.     

Study of some common biochemical bone turnover markers in postmenopausal women

Markers of bone formation in serum include total and bone specific alkaline phosphatase, osteocalcin and Type 1 collagen carboxy terminal extension peptide. Bone resorption can be assessed by measuring plasma tartarate resistant acid phosphtase and urinary excretion of collagen degradation products: hydroxyproline, hydroxylysine glycosides and more recently the pyridinium crosslinks and associated peptides. We compared the excretion of hydroxyproline in women of reproductive age group to those of menopausal age group and found a significant difference in the two age groups. Urinary hydroxyproline was found to be significantly raised in post menopausal women. Thus hydroxyproline maybe used as the earliest indicator in the prognostic assessment of postmenopausal women of their risk of developing osteoporosis and fracture.     

Determining friction and effective loading for sled sprinting

Understanding the impact of friction in sled sprinting allows the quantification of kinetic outputs and the effective loading experienced by the athlete. This study assessed changes in the coefficient of friction (µ_k) of a sled sprint-training device with changing mass and speed to provide a means of quantifying effective loading for athletes. A common sled equipped with a load cell was towed across an athletics track using a motorised winch under variable sled mass (33.1–99.6 kg) with constant speeds (0.1 and 0.3 m · s^?1), and with constant sled mass (55.6 kg) and varying speeds (0.1–6.0 m · s^?1). Mean force data were analysed, with five trials performed for each condition to assess the reliability of measures. Variables were determined as reliable (ICC > 0.99, CV < 4.3%), with normal-force/friction-force and speed/coefficient of friction relationships well fitted with linear (R² = 0.994–0.995) and quadratic regressions (R² = 0.999), respectively (P < 0.001). The linearity of composite friction values determined at two speeds, and the range in values from the quadratic fit (µ_k = 0.35–0.47) suggested µ_k and effective loading were dependent on instantaneous speed on athletics track surfaces. This research provides a proof-of-concept for the assessment of friction characteristics during sled towing, with a practical example of its application in determining effective loading and sled-sprinting kinetics. The results clarify effects of friction during sled sprinting and improve the accuracy of loading applications in practice and transparency of reporting in research.
