This paper introduced the history, development, and major accomplishments of the urban and community forestry movement, highlighted the economic, ecological, environmental, and social values of forests and trees to communities, and discussed issues and trends of the urban and community forestry program in the United States.展开更多

Originally, we had wanted to interview him as he was the medical director of the first acupuncture center in the United States that opened in the early 1970s. We wanted to know more about that center＇s history. Prior to visiting Dr. Coan, we found an article written by Dr. Sherman Cohn that mentioned Dr. Coan. The article noted that Dr. Coan was the founder of the American Association of Acupuncture and Oriental Medicine, which is the national association of acupuncturists and Chinese medicine practitioners in the United States.展开更多

Both Fu Chang and Xun Chuo were employed as high-ranking officials, with a background of being from the Central Plain, by the regime of the Later Zhao founded by Shi Le. Their purpose for writing the two books was to provide guidance for the regime's institutional establishment. The collapse of Shi Le's regime led to the flow of people and their possessions to the south. During these movements, the two books along with other materials and records were brought to Jiankang and then contributed to the institutional and cultural development in the middle and late Eastern Jin Dynasty. As historical facts and references for political reformation, these books revealed the duality of institutional writings. The collection and dispersion of books after the Disaster of Yongjia, as well as the social and cultural changes, should be placed in a wider political process for further examination.展开更多

Fundamental principles of liberty and property found in the United States of America’s (“US”) legal system, from its origins to recent US Supreme Court decisions, continue to positively benefit holders of real estate in the Southern US, through a deep-rooted public policy of supporting private property rights and rural economic development. This stable rule of law enhances the long-term adaptability and sustainability of timberland as an asset class. This article is a commentary. It combines legal research methodology with the observations and conclusions of the authors. Its purpose is to demonstrate that the existence of alienable, documentable ownership, and related property rights create inherent stability and security. These principles form the basis of a culture that is defined by the rule of law and is “open for business.” This business mindset is particularly prevalent in the Southern US.展开更多

From 44 towns in the State of Burgundy, their pharmacists have been identified and based on studies on the population in European mediaeval towns, the number of inhabitants per apothecary could be established for the years 1400, 1440, 1480, 1520, 1560 and 1600. A distinction among small towns, medium sized and big towns has been made. In towns with less than 2,500 inhabitants usually .just one pharmacist is present. Because of the limited number of potential clients, it concerns often a town-pharmacist （partly） paid by the magistrate and with additional privileges or a monopolized position. A client-potential of 3,500-4,000 or higher allowed the pharmacist in the territory of the State of Burgundy to be commercially successful in the 15th and 16th century.展开更多

In 1979, he moved the clinic to Rockville, Maryland and continued to practice acupuncture there for over 30 years. He is a well-known licensed acupuncturist （LAc）, one of the developers of the acupuncture profession, and a scholar of acupuncture and traditional Chinese medicine （TCM）. He has treated two US Governors （In the US, the title Governor refers to the chief executive of each state or insular territory and the political and ceremonial head of the state.） and many sports stars.

The results show that there exists a linear relationship between the seepage discharge and osmotic pressure in sandstone fissure under each level of confining pressure. With the increasing in the confining pressure,the permeability of the fracture decreases,but the decreasing rate is changeing. During the unloading process,the fracture seepage velocity cannot be fully recovered to the size of the loading process. Therefore,in the unloading process of the confining pressure,the recovery of fracture permeability shows obvious hysteresis effects. The flow rate of the fracture remains unchanged during five cycles of loading and unloading processes of the confining pressure. In each cycle,the evolution character of the flow rate with the confining pressure remains unchanged. These experiments show that the seepage characteristics of sandstone and granite fractures are not the same under the same stress state.展开更多

Based on the landing data compiled by Food and Agriculture Organization combined with trophic information of relevant species in Fish Base, we evaluated the status of marine fisheries from 1950 to 2010 for different coastal states in Pacific, Atlantic and Indian Oceans. We found that the phenomenon of ＂fishing down marine food webs＂ occurred in 43 states. Specifically, 27 states belonged to ＂fishing-through＂ pattern, and 16 states resulted from ＂fishing-down＂ scenario. The sign of recovery in MTL was common in the Pacific, Atlantic and Indian Oceans（occurred in 20 states）, but was generally accompanied by significantly decreased catches of traditional low trophic level species. In particular, 11 states showed significant declining catches of lower trophic levels. The MTL-based assessment of ＂fishing down marine food webs＂ needs to be interpreted cautiously.展开更多

However, the establishment of schools for ACM signaled the establishment of ACM as an established profession in the U.S. One of the first persons who wanted to set-up a school for Chinese medicine in the U.S. was Dr. Tom Foo Yuen （谭富园, August 7, 1858 - July 10, 1947） during the late 1800s in Los Angeles （LA）, California. However, it was not until 1969 or 1970 that the first informal ACM school was actually established in the U.S. This school was called the Institute for Taoist Study, and was located in LA. However, this school was not registered with the local government and Dr. Gim Shek Ju was the sole teacher at that time.展开更多
