把对外开放推向内地的经济走廊选在哪里?——历史选择了长江!

共同富裕路在何方共同富裕,除了把对外开放推向国土腹地之外,别无选择。这条深入内地的经济走廊选在长江。 1990年4月18日,国务院总理李鹏在上海宣布了关于开发上海浦东新区的决定,把中国改革开放的前沿推进到了以浦东为龙头的长江流域。1991年10月,七届人大常委会第22次会议批准芜湖、九江、武汉、岳阳、重庆五个沿江港口城市正式对外开放,享受

Scientific conviction amidst scientific controversy in the transatlantic livestock and meat trade

A century before the outbreak of bovine spongiform encephalopathy (BSE), Great Britain and North America grappled with pleuro-pneumonia - a disease in cattle that had equally maddening consequences. Towards the end of the 19th century, this condition was at the heart of a transatlantic trade dispute that lasted for decades and attracted the attention of livestock farmers, diplomats, shipping moguls, veterinarians, public health regulators and journalists the world over. Scientific controversy aggravated the situation when there were doubts about the scientific judgment of Privy Council veterinary officials, who were simultaneously conducting disease-diagnosis activities and pushing for tighter regulations at British ports. At this point, William Williams, principal of the New Veterinary College in Edinburgh, waded into this troubled arena. His strong convictions spawned a long-running disagreement with the British Government over the diagnoses of pleuro-pneumonia in cattle imported from the USA and Canada.     

Growth in biomedical publications and scientific institutions in the Emirates (1998–2004): an Arabian renaissance?

OBJECTIVES: The United Arab Emirates is witnessing a rapid development in population and infrastructure, leading to an expansion in the educational field and the health care system, including universities, hospitals and research institutes. One potential outcome of this development is an increase in biomedical research publications. This was examined in this study. METHOD: Searches were made of three databases; PubMed, Current Contents and embase. All records from these databases related to the Emirates were downloaded and cross-referenced. Duplications were removed as well as erroneous records. A total of 1369 publications during 1998-2004 were obtained. RESULTS: Analysis of these records revealed that the Faculty of Medicine and Health Sciences, located at the federal University, was responsible for 48% of all biomedical publications. All hospitals together accounted for 24%, while other universities and other research institutes accounted for 13 and 14% respectively. Further analysis revealed that there had been no further growth in the number of publications since 1998. This is in contrast to the increasing number of institutions that have been set up in the 1998-2004 period; from 29 to 112. CONCLUSION: The Emirates are witnessing a rapid development in universities, colleges, hospitals and research centres. The ratio of publications, as yet, has not kept up with this development. The enormous growth in institutes, however, may, in time, herald an Arabian renaissance in scientific activity and related publications.     

Continuing education module: finding the path

In this guest editorial, the challenges and pain of childbirth are presented as essential components of important life transitions. The role of pain in childbirth is explored. Childbirth is discussed as a "flow experience," and recommendations for assisting women to meet the challenges of labor and birth are presented.     

Temporal integration in Pavlovian appetitive conditioning in rats

We used an appetitive sensory preconditioning procedure to investigate temporal integration in rats in two experiments. In Phase 1, rats were presented with simultaneous compound trials on which a 10-sec conditioned stimulus (CS) X was embedded within a 60-sec CS A. In Group Early, CS X occurred during the early portion of CS A, whereas in Group Late, CS X occurred during the latter portion of CS A. In Phase 2, CS X was paired simultaneously with sucrose. On a subsequent test with CS A, the rate of magazine entries peaked during the early portions of the stimulus in Group Early and during the latter portions of the stimulus in Group Late (Experiments 1 and 2). Similar response peaks were not observed on tests with a control stimulus that had been presented in compound with a stimulus that did not signal reward (Experiment 2).
