基于“雨课堂”的教学模式设计与实践——以《森林生态学》课程为例

“雨课堂”是一种基于微信平台的“互联网+教育”智慧教学模式,通过同步两个线上和线下通道,有效地实现了课堂教学的翻转。本文以水土保持与荒漠化防治专业的专业基础课“森林生态学”为例,针对该课程内容多且课时少的矛盾,介绍了基于“雨课堂”的教学模式的新的尝试,重点阐述了“雨课堂”在课前推课、课堂互动、课后测评等教学关键环节中的特点和优势,并对“雨课堂”使用前后的学生成绩进行比较分析,结果表明“雨课堂”能够明显提高学生学习的效果。     

Management of Primary Injuries of the Medial Collateral Ligament of the Carpus in Two Horses

This case report describes the successful management of two horses with medial carpal collateral ligament injury. This is a rare cause of forelimb lameness and existing reports indicate a poor prognosis for return to athletic function with conservative management. Both horses were treated with a combination of box rest with controlled exercise and high-intensity laser therapy (HILT). Both horses returned to previous athletic function, one at Grand Prix level dressage and one at Novice level eventing. With appropriate management, the prognosis for carpal collateral ligament injury may be good. From this report, it is unclear whether a rehabilitation program including HILT offers improved prognosis compared with a rehabilitation program alone.     

Prediction of soil water retention properties after stratification by combining texture,bulk density and the type of horizon

Among the numerous pedotransfer functions (PTFs) published, class‐PTfs have received little attention because their accuracy is often considered limited. However, recent studies show that performance of class‐PTFs can be similar to the more popular continuous‐PTFs. In this study, we compare the performance of PTFs that were derived from a set of 456 horizons collected in France grouped by combinations of texture, bulk density and type of horizon (topsoil and subsoil). The performance of these class‐PTFs was validated against water retained at ?33 and ?1500 kPa. Our results show that the best performance was obtained with class‐PTFs that used both texture and bulk density (texture‐structural class‐PTFs). They also showed that incorporation of horizon type into the PTF did not improve prediction performance. Comparison of performance at ?33 and ?1500 kPa showed very little difference, thus indicating no bias according to the value of water potential. Finally, the class‐PTFs developed are well suited for predicting water retention properties at the continental and national scales because only very basic soils data are available at these scales. A map of the available water capacity (AWC) was established for France using the 1:1 000 000 Soil Geographical Database of France and an averaged AWC of 104 mm was computed for France.
