A comparison of the mystery motivator and the Get 'Em On Task interventions for off‐task behaviors

Attending to instruction is a critical behavior for academic success. Many elementary school teachers, however, identify disruptive and inattentive classroom behaviors as key barriers to students' successful educational performance. This study examined the impact of two class‐wide positive behavior support programs. The Mystery Motivator and Get 'Em On Task interventions were implemented in an alternating treatments design with fifth grade participants to decrease off‐task behaviors. Results indicated that both interventions effectively decreased off‐task behavior at the class‐wide level. Implications and suggestions for future research on evidence‐based behavioral interventions are discussed. © 2011 Wiley Periodicals, Inc.     

Increased plasma zonulin in patients with sepsis

Introduction:

Zonulin is a eukaryotic protein structurally similar to Vibrio cholerae’s zonula occludens toxin. It plays an important role in the opening of small intestine tight junctions. The loss of gut wall integrity during sepsis might be pivotal and has been described in various experimental as well as human studies. Increased levels of zonulin could be demonstrated in diseases associated with increased intestinal inflammation, such as celiac disease and type 1 diabetes. We therefore investigated the role of plasma levels of zonulin in patients with sepsis as a non-invasive marker of gut wall integrity.

Materials and methods:

Plasma level of zonulin was measured in 25 patients with sepsis, severe sepsis or septic shock according to ACCP/SCCM criteria at the first day of diagnosed sepsis. 18 non-septic post-surgical ICU-patients and 20 healthy volunteers served as control. Plasma levels were determined by using commercially available ELISA kit. Data are given as median and interquartile range (IQR).

Results:

Significantly higher plasma concentration of zonulin were found in the sepsis group: 6.61 ng/mL (IQR 3.51–9.46), as compared to the to the post-surgical control group: 3.40 ng/mL (IQR 2.14–5.70) (P = 0.025), as well as to the healthy group: 3.55 ng/mL (IQR 3.14–4.14) (P = 0.008).

Conclusion:

We were able demonstrate elevated levels of plasma zonulin, a potential marker of intestinal permeability in septic patients. Increased zonulin may serve as an additional mechanism for the observed increased intestinal permeability during sepsis and SIRS.     

English Reading Effects of Small‐Group Intensive Intervention in Spanish for K–1 English Learners

In this article we report small, but statistically significant, effects of brief supplemental instruction on English reading by Spanish‐speaking kindergartners (N = 37) who performed poorly on a bilingual battery of phonological‐processing tasks. Intervention design was compatible with the Reading First initiative and with research on use of multitiered intervention strategies for preventing reading failure among young monolingual students (e.g., L. S. Fuchs & Vaughn, 2003). We describe a Core Intervention Model (CIM) comprised of specific instructional behaviors that teachers might easily learn and employ regardless of curriculum, and discuss implications of our findings for building multitiered preventative instruction for young English learners.
