Classical-style poetry is a neglected genre in the study of Chinese American literature. Except for the Angel Island Poetry and the Songs of Gold Mountain （Jinshan geji 金山歌集）, no substantial research has been done on the enormous amount of classical-style poems published in San Francisco and New York. This article attempts to explore this uncharted territory by examining the poetry of Tung Pok Chin 陈松柏（1916-88, aka Lai bing Chan 黎屏尘） and his story as a Chinese immigrant. Chin moved to the United States in 1934 as a paper son. He joined the American navy during World War II and eventually established his own laundry business in Brooklyn. Since the late 1940s, Chin published a significant amount of his classical-style poetry in the China Daily News （Meizhou huaqiao ribao 美洲华侨日报）, a left-wing newspaper operated by the pro-communist Chinese Hand Laundry Alliance. With the help of his daughter, he also wrote a memoir in English narrating his assimilation into American society. His poetry, though not particularly refined, similarly records his experiences and comments regarding American life and politics. Based on the source materials found in the Tung Pok Chin Papers archived in New York University, his memoir, and the poems he published in the China Daily News, herein I illuminate how Chin adopted a traditional form of poetry as his expressive vehicle and, with the narrative power of his English memoir, how he used his poems to construct a social identity. The article also relates Chin＇s work to the broader context of Asian American studies, as well as the classical poetry community and its development in New York, and ponders his significances in the history of Chinese American literature.

BACKGROUND： Acupuncture has been used as a treatment for cognitive impairment. OBJECTIVE： This review assesses clinical evidence for or against acupuncture as a treatment for cognitive impairment. This review also discusses the proposed mechanism（s） that could link acupuncture to improved cognitive function. METHODS： We searched the literature using PolyUone search from its inception to January 2013, with full text available and language limited to English. Levels of evidence were examined using Oxford Centre for Evidence-based Medicine-Levels of Evidence （March, 2009）. RESULTS： Twelve studies met the inclusion criteria： 3 human studies and 9 animal studies. Levels of evidence ranged from level lb to level 5. CONCLUSION： Most animal studies demonstrated a positive effect of acupuncture on cognitive impairment. However, the results of human studies were inconsistent. Further high-quality human studies with greater statistical power are needed to determine the effectiveness of acupuncture and an optimal protocol.

A revival of ci writing was witnessed in the qing dynasty. Emerging with this resurgence was the founding of scores of ci societies. After the fall of the Qing, some loyalists and traditional literati, following the examples of their predecessors, joined together to form a number of ci societies in Republican China. For loyalist-lyricists such as Zhu Zumou, ci writing was not just one of the effective ways to convey their memories of the past. It also meant to be a gesture of practicing and preserving traditional Chinese culture. However, due to ideological bias, their works and the vitality of c/she did not receive sufficient attention from literary historians in the past. This paper attempts to reveal and examine the interesting features of c/she in the Republican era, asserting that within the collective voice of and harmonious correspondence among the traditional lyricists, there were always some dissonances occurred. First I delineate a general picture of ci societies in Republican China, explicating the geographical distribution and social networks of ci lyricists and why lyricists from the Qing loyalist faction can associate with members of the anti-Manchu Southern Society （Nanshe）, and what this phenomenon means to us. Then I focus on the Foam Society （Oushe）, the ci society formed in Shanghai before the Japanese occupation of the city, and its group ci composition. Besides recounting Oushe members＇ backgrounds and the details of their ＂refined gatherings,＂ I will bring into light the multifaceted thematic and stylistic features displayed in the members＇ works.

Linear rolling guideways(LRGs) play an important role in precision engineering. In the pre-rolling region, the hysteretic friction force exerts great impacts on the positioning accuracy. Numerical and experimental studies of the hysteresis of friction force are presented in this paper. A model, which is based on the stripe theory and the simplified theory of rolling contact, is built to describe the transient hysteresis of the friction force. Then, the model is modified by taking the anelasticity effect into consideration. Experimentally, a linear motor direct-drive setup is utilized to measure the transient asymmetrical hysteresis of the friction force in the pre-rolling region of an LRG. The influences of the pre-rolling displacement and the dwelling time on the asymmetrical hysteresis of the friction force are studied. The numerical and experimental results are well correlated, which shows good accuracy of the model. The transient asymmetrical hysteresis of friction force in the pre-rolling region of LRGs can thus be determined using the model.

Steroid hormones, alkylphenol ethoxylates（APEOs） and phthalic acid esters（PAEs） are emerging endocrine disrupting chemicals（EDCs） that can interfere with the endocrine function in organisms at low concentrations. The occurrence, distribution behavior, removal rate and the fate of 31 target EDCs in sewage treatment plants, which consist of various treatment facilities and receiving water in Hong Kong, were investigated. Estrone,nonylphenol-di-ethoxylate and diethyl phthalate were found to be dominant in each group of influent samples with concentrations ranging from 11–33, 747–3945 and 445–4635 ng/L,respectively. Conversely, progesterone, nonylphenol-mono-ethoxylate and bis（2-ethylhexyl）phthalate were the most abundant in dewatered sludge, with concentrations ranging from 0.9–237, 75–19,743 and 4310–37,016 ng/g（dry weight）. The removal rates of primary sedimentation and disinfection approaches were lower than 30% for most of the chemicals,while those of activated sludge and reverse osmosis were greater than 80% for more than two-thirds of the compounds, noticeably decreasing the estrogenic risk of sewage discharged into the environment. Steroid hormones were removed via biological degradation, while some APEOs and PAEs adsorbed to the sludge. Victoria Harbor poses a low to medium estrogenic risk mainly contributed by estrone and estradiol and deserves attention.
