Zusammenfassung. Ausgehend von einem Good-strategy-user-Modell wird die Wirksamkeit eines Trainings allgemeiner Lernkompetenzen untersucht. 23 lernschwache, jedoch durchschnittlich intelligente Grundschüler (2., 3. und 4. Klasse; Altersdurchschnitt 9.5 Jahre), erhielten ein Training, das ihnen Lernstrategien und die dafür notwendigen Voraussetzungen (Begriffsbildung, Textverständnis, Gedächtnisstrategien) vermittelte. 15 Kinder blieben als Kontrolle ohne jede Behandlung. Vor und nach dem Training wurden die Schulleistung, die kognitiven Lernvoraussetzungen und das Lernverhalten aus Sicht des Klassenlehrers, der Eltern und der Kinder selbst ermittelt. Die Trainingsgruppe verbesserte sich gegenüber der Kontrollgruppe in allen Variablen; es werden hochsignifikante Interaktionseffekte zugunsten der Trainingsgruppe mit jeweils großen Effektstärken (d zwischen 0.8 und 2.2) erreicht. Im Einzelnen verbesserte sich die Schulleistung substanziell (d = 1.3) und das Lernverhalten der Kinder wird von Eltern, Lehrern und den Kindern als deutlich verbessert eingeschätzt. Die Ergebnisse werden als Beleg für die Wirksamkeit des allgemeinen Lerntrainings und als indirekte Bestätigung des Good-strategy-user-Modells interpretiert.

Abstract: The implementation of da'wah must be designed and packaged properly so as to produce an effectiveness and efficiency in da'wah. Therefore, there needs to be good management in the process of implementing da'wah starting from planning, organizing, mobilizing, controlling, and evaluating da'wah. The process of implementing da'wah must have a good strategy, method and management in order to produce quality da'wah and achieve the stated preach goals. Key Words : Management, da’wah

Apoptosis of hepatocyte, under ischemia/reperfusion (IR) conditions, has been identified as an essential process in the progression of liver transplantation. Under these conditions, mitochondria can become a threat to the cell because of their capacity to generate reactive oxygen species (ROS). Additionally, ROS overproduction may induce inflammation. As ROS accumulation appears to cause hepatocyte damage or death, there has been considerable interest in identifying the candidate natural products involved and in developing strategies to reduce oxidative stress. In this study, we use Danshensu as a candidate product to speculate whether has the protective effect on apoptotic hepatocyte upon IR. To speculate the apoptotic phenomena was reversed by Danshensu, we detected the p53, cleaved-caspase 3 expression by western blotting, as well as caspase-3 activity. Additionally, we analyzed the ROS levels by 2′,7′-dichlorofluorescin diacetate (DCF-DA) staining. We also detected the cell viability by WST-1. Results showed that Danshensu alleviated hypoxia-caused cell apoptosis via ROS overproduction. We suggested that Danshensu is a good strategy for treating hepatocyte damage upon IR.

This chapter covers multiple regression and links statistical inference to general topics such as lurking variables that arose earlier. Many examples can be used to illustrate multiple regression, but we have found it useful to come to class prepared with a specific example, with computer output (since our students learn to run the regressions on the computer). We have found it is a good strategy to simply use a regression analysis from some published source (e.g., a social science journal) and go through the model and its interpretation with the class, asking students how the regression results would have to differ in order for the study’s conclusions to change. The chapter includes examples that revisit the simple linear model of height and income, involve the class in models of exam scores, and fit a nonlinear model (for more advanced classes) for golf putting.

Abstract Background Physical inactivity is worldwide considered one of the biggest public health problems of the 21st century. WHO recommended in children, at least 60 minute of Moderate Vigorous Physical activity (MVPA) per day, but low percentages comply with guidelines. Considering that children spend many hours at school, classroom is the ideal setting to increase their PA. Active Breaks (AB) are a 5-15-minute bouts of PA led by the teachers during academic lessons. The aim of the Imola AB study is to implement a 1-year intervention based on AB (10min/3per-day) in primary school as a new strategy to reduce inactivity. We present the baseline results. Methods Quasi-experimental pre-post study in 6-10aged primary school children, in Imola(Italy).We evaluated PA level with Actigraph accelerometers: time (in minutes) spent in MVPA Weekly and Daily (W-MVPA; D-MVPA) and Weekly Sedentary behaviours (W-SB). Results We recruited 152 children: N = 110 in Active Breaks experimental group (AB) and N = 42 in control group (CG). Actigraph's analysis showed that 42,5% of children in the ABG vs 31.0% in the CG reach the WHO recommendation (p=ns). We investigated baseline differences between groups using ANOVA dividing children by grade. In 3-4 grades: W-MVPA (AB = 318.3±15.5 vs CG = 310.4±98.0 p = 0.78); D-MVPA (AB = 53.0±20.3 vs CG = 51.8±16.3 p = 0.79);W-SB (AB = 6,687.5±375.3 vs CG = 6,754.7±281.0 p = 0.45). In 1grade: W-MVPA (AB = 376.1±127.9 vs CG = 300.3±120.0 p = 0.02); D-MVPA (AB = 62.7±21.3 vs CG = 50.0±20.0 p = 0.02); W-SB (AB = 6,436.0±496.0 vs CG = 6,373.3 ±1,532.0 p = 0.7). Conclusions Only the 39.2% of the total sample met the 60-minute/day of MVPA recommended. We found no significant baseline differences in PA level measured by Actigraph between CG and AB, excepted in 1 grade. The intervention implemented in the Imola AB study could be a good strategy to reduce sedentary in children and reach the WHO recommendation, thus contributing to the aims of the new Global Action Plan on PA 2018-2030. Key messages Less than 50% reach the WHO recommendations of PA. AB implemented in the Imola Study could be a public health school-based strategy to reduce sedentary and increase healthy behavior in children. Active breaks (AB) are emerging as a good strategy to increase the PA level, reducing the time in sedentary habits.
