Delivering forestry courses online:experiences,lessons learned,and future of forestry online education in the Asia Pacifi c

Innovation in forestry education is needed to address changing contexts of the positionality of forests.This is particularly signifi cant in the Asia–Pacifi c region,where deforestation and degradation are high.However,the accessibility of high-quality forestry education to address changing regional and global contexts is lacking.A series of innovative sustainable forest management(SFM)open education resource(OER)courses were developed and implemented to improve the accessibility of SFM education to enhance teaching quality,curriculum,and research capacity of universities in the Asia-Pacifi c Region.To evaluate the SFM-OER program in terms of student experiences,this study investigated student achievement,perceived success of the pedagogical approach and instructional design,and perceived eff ectiveness of the learning activities in promoting active and transformative learning through the assessment of a 1,191-course feedback survey between 2018 and 2020,including the global pandemic.This study revealed that the program attracted diverse student demographics,including a higher proportion of female students majoring in forestry,ecology,and other environmental studies.Their primary motivation to participate in the courses was to gain international experience,followed by the fl exibility of online learning,mandatory course requirements,and earning course credits.Students were satisfi ed with the Canvas learning management system.Most students spent less than 5 to 10 h of their weekly time in the course and agreed or strongly agreed that the workloads were manageable.Students refl ected positively on various learning activities and assignments,such as watching lecture videos,taking quizzes,reading and summarizing,having discussions,and peer review writing.However,they did not clearly prefer specifi c learning activities,signifying the importance of using diverse learning activities to satisfy diverse individual learning styles in online settings.This analysis contributes to the further development of student-centered pedagogical development for online learning and provides insight into the ways forward for online higher forestry education,while repurposing existing OER courses in a post-Covid-19 era.

Lessons learned from hydrothermal to hot dry rock exploration and production

In this paper,we investigate geothermal exploration and production in 189 hydrothermal projects and 42 hot dry rock projects around the world.The hydrothermal fields for a working hydrothermal system to generate electricity should have the elements of heat source,water-saturated porous or fractured reservoir,caprock,heat transfer pathway,and good heat preservation condition and geothermal power energy intensity of 10-20 MW per km^(2)within at least 5 km^(2)area in tectonically active region.The hot water or steam flow rate in this hydrothermal system is normally larger than 40 L/s with temperature of 150℃or above.The power generated from enhanced geothermal system(EGS)in hot dry rock projects are generally less than 2 MW because the flow rate in most cases is much less than 40 L/s even with the hydraulic fractures using the modern stimulation technology learned from the oil and gas industry.The natural fracture in the subsurface is generally beneficial to the hydraulic fracturing and heat recovery in the hot dry rock.Moreover,the hydraulic fracture parameters,injection rate and well spacing,drilling strategy should be properly designed to avoid the short-circuit between injector and producer and low heat productivity.In the future,CO^(2)enhanced geothermal recovery associated with CO^(2)sequestration in the high temperature oil,gas,and geothermal fields maybe a good choice.On the other hand,both nearreal-time seismic monitoring to limit the pumping rate and the closed-loop of the Eavor-Loop style system without hydraulic fracture can contribute greatly to heat recovery of hot dry rocks and mitigate the risks of the hydraulic fracturing induced earthquake.Furthermore,the hybrid solar and geothermal system performs better than the stand-alone geothermal system.

Lessons learned from Wenchuan earthquake for seismic safety of large dams

This paper describes some special features of the Wenchuan earthquake that affected dam safety. Damage and performance of dams, primarily for four dams over 100 m high located in the affected earthquake area, are briefly described. Lessons learned related to dam safety from this devastating earthquake are preliminarily drawn. As the seismic safety of high dams during strong earthquakes has gained more attention around the world, some critical issues related to dam construction in China are considered and extensively discussed. Questions such as ＂Why is dam construction necessary in earthquake prone countries such as China？＂, ＂Can we accurately evaluate the seismic safety of high dams in China？＂, ＂Did reservoir impounding of the Zipingpu and Three Gorges Projects trigger the Wenchuan Earthquake in some way？＂ and ＂What is the strategic priority of dam safety for large dams in China？＂ are discussed. Finally, the corresponding tactics with response to the challenge are suggested and recent preliminary progress mainly achieved in IWHR is briefly introduced.

Medical mountain rescue in the Yushu Earthquake: Have lessons been learned?

On April 14,2010,an earthquake reaching Richter scale 7.1 struck Jiegu Town of Yushu,a mountain rescue operation promptly launched. All injurers had a direct assess to take medical care,and were immediately rescued and rapidly evacuated by air to Xining and Golmud at lower altitudes and admitted to advanced hospitals. Almost all of the injurers have been completely recovered. Yushu Earthquake was one of the highest earthquakes in the world,with a high incidence of acute altitude illness,which was observed in about 80 % of the lowland rescuers at an altitude of 4 000 m."Rescue the rescuers"became the major task of Qinghai-Tibetan rescue teams,all the severe patients were rapidly descended to Xining and treated promptly and effectively. The outcome was excellent,all patients survived. After the earthquake,it is a long and arduous task to reconstruct what has been destroyed. Medical teams continue to work in the Yushu Earthquake area because about 30 000 workers and carders are now here for rebuilding the earthquake center. Thus the prevention and treatment of altitude illness are still critical tasks for medical teams. Although all the fights are successful,there are more experiences and lessons we have learned from the medical mountain rescue during the earthquake and the reconstruction,and reports here are to sum up our experiences from the medical mountain rescue operation in Yushu Earthquake and draw the lessons that we should learn. With the increasing of earthquake probability occurring in the Qinghai-Tibetan Plateau,we also should prepare against earthquake disasters and for further rescue training in the high mountains.

Effectiveness Study of Lead-in of New Lessons in Classroom Teaching

English teaching is an integral part of education,which shoulders the responsibility of rendering rudimentary knowledge of English to the students,providing the students with the listening,speaking,reading and writing ability,as well as the obligation of carrying out ideological education and cultivating their noble and healthy sentiment.In teaching,the teachers should pay special attention to the students' thirst for English learning and give full play to their initiative,which demands enough lead-in preparation before class.The lead-in of new lessons bears a direct impact on the quality of the classroom teaching.This thesis will make an analysis of this problem in two aspects.

Retinal ganglion cell neuroprotection by growth factors and exosomes:lessons from mesenchymal stem cells

Retinal ganglions cells （RGCs） are responsible for propagating electrochemical information from the eye to the brain along their axons which make up the optic nerve. The loss of RGCs is characteristic in several conditions such as glaucoma and trau- matic optic neuropathy and leads to visual loss and blindness. While no therapy exists to directly treat RGCs, the use of bone marrow-derived mesenchymal stem cells （BMSCs） has shown promise in eliciting significant RGC neuroprotection.

Impact of host genetics on gut microbiome: Take-home lessons from human and mouse studies

The intestinal microbiome has emerged as an important component involved in various diseases.Therefore,the interest in understanding the factors shaping its composition is growing.The gut microbiome,often defined as a complex trait,contains diverse components and its properties are determined by a combination of external and internal effects.Although much effort has been invested so far,it is still difficult to evaluate the extent to which human genetics shape the composition of the gut microbiota.However,in mouse studies,where the environmental factors are better controlled,the effect of the genetic background was significant.The purpose of this paper is to provide a current assessment of the role of human host genetics in shaping the gut microbiome composition.Despite the inconsistency of the reported results,it can be estimated that the genetic factor affects a portion of the microbiome.However,this effect is currently lower than the initial estimates,and it is difficult to separate the genetic influence from the environmental effect.Additionally,despite the differences between the microbial composition of humans and mice,results from mouse models can strengthen our knowledge of host genetics underlying the human gut microbial variation.

The Development of Danish Agriculture and Agribusiness： Lessons to Be Learned in a Global Perspective

The agri and food industry is a major industrial sector in Denmark. Compared to other countries on a similar level of economic development Denmark has an extremely important agriculture and agribusiness sector. Danish agri and food cooperatives seem to have been successful in obtaining international competitiveness. The transformation and the structural development of the cooperative sector have more or less been completed. The development of the industrial structure among Danish agricultural cooperatives has been very rapid during the latest decades. Through mergers and acquisitions the number of firms has fallen dramatically, and the result has been increasing concentration ratios in almost all groups of the food industry. Structural development, concentration and globalization in recent decades have resulted in agri and food companies now being among the largest in Europe. To a large extent, agriculture all over the world faces similar problems and challenges. For this reason, it is essential that know-how, experiences and lessons can be transferred and adopted by agriculture in other countries around the world. In many ways, the experience and the success behind Danish agriculture and agribusiness can be transferred to other countries. However, profound studies of specific needs and conditions are necessary.

How the brain can rewire itself after an injury: the lesson from hemispherectomy

Does a post-lesional rewiring exist in the central nervous system （CNS）？ Whereas neuroimaging and neuromodulation techniques illustrate the extensive cortical reshaping after a brain injury, the remodeling of ascending and descending neuronal pathway is more difficult to be investigated. Here, we discuss how the studies dealing with hemispherectomy （HS） can provide interesting information about the functional and anatomical reorganization which take place after an extensive unilateral lesion. Indeed, studies in humans and animal models of HS clearly illustrate that the brain is capable of a widespread rewiring between the contralesional cortices and the subcortical structures as well as the medullary segments linked to the affected side of the body.
