Implications of a Cognitive Science Model Integrating Literacy in Science on Achievement in Science and Reading: Direct Effects in Grades 3–5 with Transfer to Grades 6–7

Reported are the results of a multiyear study in which reading comprehension and writing were integrated within an in-depth science instructional model (Science IDEAS) in daily 1.5 to 2 h daily lessons on a schoolwide basis in grades 3–4–5. Multilevel (HLM7) achievement findings showed the experimental intervention resulted in significant and consistent direct effects in grades 3–4–5 and complementary transfer effects in grades 6–7 on both ITBS Science (+1.08 Grade Equivalent Units [GE]) and ITBS Reading (+.57 GE). Discussed are implications of the findings and related research for changing grade K-5 curriculum policy to allocate increased instructional time for integrated science instruction.     

Agricultural and science education: a socio-analysis of their intersection and positions within the educational field

It can be argued that agricultural science is one of the original forms of science education. However, over the past century, agricultural science education has habitually been perceived as an educational venue meant solely for production agriculturalists. When examining modern agricultural education we find it to be a minority within the broader field of science education, contradicting its historically stout scientific standing within the sciences. This educational shift leaves one to ponder the historic development of contemporary agricultural education. To gain deeper insight into these questions we reviewed the historical evolution of agricultural education within the United States. We then examined the professional habitus, or cultural nuances, associated with contemporary agricultural education. Next, we considered potential outcomes associated with the profession embracing post-modern perspectives within mainstream science and community-based education. Finally, we call for critical venues within agriculture education to question the status quo and challenge the acceptance of commonly held views.     

Further studies on serum arginase as indicator of hepatocellular damage

Studies on serum arginase have shown that it is having the least unexplained variation and its activity is closely related with the severity of jaundice. Arginase is thus stable, consistent, efficient, specific and sensitive to changes. It is a better indicator of hepatocellular damage.     

Career development influences of international students who pursue permanent immigration to Canada

This research focused on the career decision and planning needs of a unique group of migrants: international students who are completing their studies as temporary immigrants and who are embarking on the career journey of employment and permanent immigration. A semi-structured interview employing a Critical Incident Technique was used to assess the career influences of 19 undergraduate and graduate international students at a Canadian university. Data were analyzed using a constant comparison method and critical incident protocol. Students were motivated to remain in Canada due to enhanced job opportunities and high standard of living. Barriers to migration included the fear of not securing employment and cultural and linguistic barriers. International students would like to see campus and career services specified to the needs of international and graduate students to help them realize their goal of pursuing employment as the key to permanent immigration.     

Integrated carbon fiber electrodes within hollow polymer microneedles for transdermal electrochemical sensing

In this study, carbon fiber electrodes were incorporated within a hollow microneedle array, which was fabricated using a digital micromirror device-based stereolithography instrument. Cell proliferation on the acrylate-based polymer used in microneedle fabrication was examined with human dermal fibroblasts and neonatal human epidermal keratinocytes. Studies involving full-thickness cadaveric porcine skin and trypan blue dye demonstrated that the hollow microneedles remained intact after puncturing the outermost layer of cadaveric porcine skin. The carbon fibers underwent chemical modification in order to enable detection of hydrogen peroxide and ascorbic acid; electrochemical measurements were demonstrated using integrated electrode-hollow microneedle devices.     

Glenohumeral joint rotation range of motion in competitive swimmers

Much research has examined shoulder range of motion adaptations in overhead-unilateral athletes. Based on the void examining overhead-bilateral athletes, especially competitive swimmers, we examined shoulder external rotation, isolated internal rotation, composite internal rotation, and total arc of motion range of motion of competitive swimmers. The range of motion of registered competitive swimmers (n = 144, age = 12-61 years) was compared by limb (dominant, non-dominant), sex, and age group (youth, high school, college, masters). Significantly (P < 0.05) greater dominant external rotation was observed for both men and women high school and college swimmers, youth women swimmers, and men masters swimmers compared with the non-dominant limb. The isolated internal rotation (glenohumeral rotation), composite internal rotation (glenohumeral rotation plus scapulothoracic protraction), and total arc of motion (external rotation plus composite internal rotation) of the non-dominant limb was significantly greater than that of the dominant limb by sex and age group. Youth and high school swimmers demonstrated significantly greater composite internal rotation than college and masters swimmers. Youth swimmers displayed significantly greater total arc of motion than all other age groups. These data will aid in the interpretation of shoulder range of motion values in competitive swimmers during preseason screenings, injury evaluations and post-rehabilitation programmes, with the results suggesting that differences exist in bilateral external rotation, isolated internal rotation, composite internal rotation, and total arc of motion range of motion.     

Early Childhood Teachers’ Perceptions of the Effectiveness of Their Elementary School’s Approach to Social Emotional Learning: A Mixed Methods Study

Libraries,Mobile Devices,and the Visible College

Bryan Alexander described the digital environment that we live in, giving an extensive overview of the current state of interactive devices, particularly mobile devices, which are moving us beyond the personal computer. He covered recent major developments that have transformed the world in surprising ways in a rather short period of time. The world of apps is further expanding what these devices can do, also bringing with them more challenges to individual privacy. Gaming and augmented reality are becoming deeply embedded in much of what we do. Alexander laid out four possible futures that these contemporary developments could lead to.
