Doodling Effects on Junior High School Students’ Learning

The main purpose of this study was to assess the effects of doodling on the learning performance of high school female students in Tehran. The design of this research was a pre‐test–post‐test with a control group. A group of 169 junior high school 12–13 year‐old students was chosen for this study. After being taught a section of the Natural Science course, the students were asked to answer questions related to the lessons. After that, their grades were used as the pre‐test scores. The post‐test was carried out after the devised treatment. During ten sessions of the same course and teacher, the students were each given a blank sheet of paper and were asked for doodling if they felt like doing it. After each session, a couple of relevant written questions were asked to evaluate how well students had learned the lessons. The experiment and control group both consisted of 27 randomly selected students; participants in the experiment group were doodlers and those in the control group did not doodle. To evaluate the doodling effect a t‐test analysis was performed. Comparison of the grades showed that the experiment group outperformed the control group significantly.

复合酸化剂对断奶仔猪抗腹泻效果和生产性能的影响

通过体外实验和断奶仔猪饲养试验研究了包被复合酸化剂(简称复合酸化剂)的抑菌效果及其对断奶仔猪抗腹泻效果和生产性能的影响.体外试验结果表明,采用抑菌圈法对不同浓度的复合酸化剂进行比较时,以0.2%的浓度显示出较强的抑菌效果,对大肠杆菌、沙门氏菌和乳酸杆菌的抑菌圈直径分别达到了15.0、16.8和13.0 mm.仔猪饲养实验结果表明:与不合酸化剂的对照组或有机酸化剂组相比,在基础日粮中添加了0.2%的包被复合酸化剂可以进一步提高仔猪的生长速度及饲料转化率,同时可以降低仔猪的腹泻率.

The effectiveness of workflow management systems: A longitudinal study

Workflow management systems coordinate and allocate work through the various stages of executing business processes. The benefits of such systems appear pervasive, but no hard data is available that confirms that their implementation improves organizational performance. In part, this is due to the difficulty of measuring the effects of enterprise-wide initiatives in general. In this paper, the results are presented of a longitudinal, multi-case study into the effectiveness of workflow management technology. The study builds on a novel methodology that combines field work and computer simulations. Through its application, the contribution of this technology to conduct business processes faster and with less effort could be quantitatively assessed. Surprisingly, only a fraction of the projects that were followed in this longitudinal study led to a fully operational implementation of a workflow management system at all. Even so, in most of the projects where such a system was introduced this resulted in substantial improvements. We present success and fail factors for the implementation of this technology within organizations, which we inferred from a follow-up analysis. The novel methodology presented in this paper is thought to be of value to track the performance effects of introducing other technologies or organization concepts as well.
