The neurocircuitries that constitute the corticostriato-thalamo-cortical（CSTC） circuit provide a framework for bridging gaps between neuroscience and executive function in attention deficit hyperactivity disorder（ADHD）, but it has been difficult to identify the mechanisms for regulating emotional problems from the understanding of ADHD comorbidity with disruptive behavior disorders（DBD）. Research based on ＂cool＇＇ and ＂hot＇＇executive functional theory and the dual pathway models,which are thought of as applied response inhibition and delay aversion, respectively, within the neuropsychological view of ADHD, has shed light on emotional responding before and after decontextualized stimuli, while CSTC circuit-related domains have been suggested to explain the different emotional symptoms of ADHD with or without comorbid DBD. This review discusses the role of abnormal connections in each CSTC circuit, especially in the emotion circuit, which may be responsible for targeted executive dysfunction at the neuroscience level. Thus, the two major domains – abstract thinking（cool） and emotional trait（hot） – trigger the mechanism of onset of ADHD.

Based on the survey of surface sediment in Xiamen Bay in October 2011, the speciation, distribution, and potential ecological risk assessment of heavy metals （Cu, Pb, Zn, Cd, and Cr） in this area were studied us-ing the sequential extraction method and ecological risk assessment method. The results indicated：（1） the total concentrations of these heavy metals were influenced by runoff, industrial wastewater, and sewage, and were all higher in the coastal area than the offshore area while the highest area of Pb was a little far-ther away from the coastal water due to atmosphere deposition;（2） sequential extractions suggested that Cu was mainly composed with residual and Fe/Mn-oxide bound fractions, Pb was bound to Fe/Mn-oxide, Zn and Cr were dominated by residual, and Cd bound to exchangeable and carbonate fractions; （3） the order of migration and transformation sequence was Cd＆gt;Pb＆gt;Cu＆gt;Zn＆gt;Cr and the degree of pollution was Cd＆gt;Pb＆gt;Cu＆gt;Zn＆gt;Cr;and （4） the ratios of the secondary and primary phases showed that Zn and Cr were both clean, Cu may be polluted, Pb was moderately polluted, while Cd was heavily polluted.

On the basis of the data of two cruises in the Changjiang River mouth during the 'rainy season' ofAugust 1981 and the 'dry season' of November of the same year, this article analyzes the horizontal distribution,the sectional distribution and the diurnal variations of total phosphorus (T. P. ), organic phosphorus (O. P. ) andphosphate (PO4), and at the same time summarizes their distributional patterns. It makes also statistic and correlative analyses on different species of phosphorus, their behaviours and characteristics of cycling process in theChangjiang Estuary.

According to data obtained in the Bering Sea during the 4th Chinese National Arctic Research Expedition, the distribution of dissolved oxygen （DO） was studied, causes of its maximum concentration were discussed, and the relationships between DO and other parameters, such as saliniW, temperature, and chlorophyll a were analyzed. The results showed DO concentration ranged from 0.53 to 12.05 mg/L in the Bering Sea basin. The upper waters contained high concentrations and the maximum occurred at the depth range from 20 to 50 m. The DO concentration decreased rapidly when the depth was deeper than 200 m and reached the minimum at the depth range from 500 to 1000 m, and then increased slowly with the depth increasing but still kept at a low level. On the shelf, the DO concentration ranged from 6.53 to 16.63 mg/L with a mean value of 10.75 mg/L, and showed a characteristic of decreasing from north to south. The DO concentration was higher in the area between the Bering Sea and Lawrence Island and was lower in the southeast and southwest of Lawrence Island at the latitude of 62°N. The formation of maximum DO concentration was concerned with phytoplankton photosynthesis and formation of the themocline. To the south of Sta. B07 in the Bering Sea basin, the oxygen produced by photosynthesis permeated to the deeper water and the themocline made it difficult to exchange vertically, and to the north of Sta. B07, the maximum DO concen- tration occurred above the themocline due to phytoplankton activities. On the shelf, the oxygen produced by phytoplankton photosynthesis gathered at the bottom of the thermocline and formed the DO maximum concentration. In the Bering Sea basin, the DO and salinity showed a weak negative correlation （r=0.40） when the salinity was lower than 33.1, a significant negative correlation （r=-0.92） when the salinity ranged from 33.1 to 33.7, and an irregular reversed parabola （r=0.95） when the salinity was greater than 33.7.

Concentrations of total mercury （THg） and methyl mercury （MeHg） were determined for 32 surface sed- iments collected along the coastal line of Fujian Province and eastern Guangdong Province. The spatial distributions of THg and MeHg and their environmental impact factors were investigated. The average con- centrations of THg and MeHg in the sediments were 31.5 ng/g and 0.096 ng/g, respectively. Both sediment THg and MeHg concentrations showed relatively high value in the Minjiang Estuary and the coastal areas of Quanzhou and Putian. The concentrations overall decreased as the distance to the shoreline increased. The correlations among environmental impact factors and THg, MeHg were analyzed. The sediment THg concentration was highly correlated to the concentrations of organic matter, copper, total nitrogen （TN） and total phosphorus （TP）, and significantly correlated to pH value of the bottom seawater and concentration of sediment sulfide. The sediment MeHg concentration was highly correlated to the concentrations of organic matter and copper, and significant correlated to the concentrations of sulfide, TN, TP and pH value of the bottom seawater.

On the basis of mixture theory of concentration of Helland-Hansen (Mao et al, 1964; Helland-Hansen, 1916), this paper takes salinity as a conservative factor in the process of dilution and mixture and selects by relating analysis the bydrological and chemical factors which are closely related to salinity. Then making use of the Q type multi-dimensions cluster analysis, we get the results that the water masses in the western Taiwan Strait include the follying: the coastal water along Fujian, Zhejiang and Guangdong Provinces, the diluted fresh water of Minjiang, jiulong and Hanjiang Rivers; the mixing water in the Taiwan Strait; upwelling cold/warm water to the northwest of the Taiwan Shoal and the upwelling water to the east of Guangdong. The mixing weter in the Taiwan Strait during spring and summer is composed of a Kuroshio branch, the surface weter of the South China Sea, outal wier along Fujian, Zhejiang and Guangdong Provinces. While in autunm and winter, it is mixed up from Kuroshio branch, the shelf weter in the East China Sea, and the coastal water along Fujian, Zhejiang and Guangdong. There is an obvious seasonal change of growth and decline in these water masses.

在数据驱动的时代,欧盟始终强调信息自决和个人隐私保护的基本权利,也非常重视数据主权问题,但这种宪法性规范不能在私人主体之间的纠纷中强制执行。中国主要从民法以及行政举措的视角来加强对隐私、信息安全及人格利益的综合保护。关于“数据保护权”的中国法律规范主要在公民个人、集体以及企业之间强制执行,但很少针对政府。我国《民法典》并没有创设“数据财产权”,我国《数据安全法》却承认数据市场,试图通过对数据进行评价和共享的程序对数据财产权进行债权式的保护。完善数据财产权的实体规范,进而将之提升至基本权利的高度、强调数字人权的保障,是一项很重要并具有迫切性的立法课题。“数据公平使用”的立法原则在个人权利保护、数字经济发展以及数据利润共享之间达成适当的平衡。一旦关于数据保护权和数据财产权的宪法框架得以确立,数字经济立法的空间将可能适当拓展。在这里,中国可以与欧盟相向而行、互相借鉴。新时代宪法秩序变迁的方向就是建立和健全技术的分权制衡机制,确立新型的“数字化监察权”。

本文关于戏仿与著作权的讨论,侧重于数码网络化对法律秩序的深刻影响以及各种创新型制度设计。作者认为,对所谓公平使用原则的考量,必须以严格区分美国模式和欧洲模式为前提;中国现行著作权法极其强调对作者人格的保护,固然有其必然性和合理性,但也很可能在不同程度上阻碍信息流通以及文化产业的发展。因此也可以说,“馒头血案”与《无极》的碰撞,其实提出了一些涉及法与社会转型的根本问题:怎样才能避免通讯技术引起著作权的解体或贬值?人际互动与大批量的契约群以及民主决定的法律程序要件之间的关系究竟应该如何重构?解答这些问题的关键是对权利处理的不同方式进行比较。
