Colonial ascidians from the Foveaux Strait region of New Zealand

Colonial ascidians collected from wharf piles and natural substrata from Bluff Harbour and Stewart Island in the South Island of New Zealand are described in this paper. Two species, Lissoclinum violaceum sp. nov. and Didemnum marineae sp. nov. are new to science and described for the first time. The ascidian fauna in this region is a mixed assemblage of southern species, species with a New Zealand-wide distribution, and two species with trans-Tasman affinities.

城市新区环境规划的"响应-调控"模型研究

针对城市新区社会经济环境系统所具有的整体性、不确定性、综合性和动态性特点,构建不确定性的新区社会经济环境系统"响应-调控"模型,包括4个关键步骤:系统动态响应模拟,情景分析与评价,优化调控模型构建,以及决策偏好与优化调控方案生成.设计3个子情景来比较分析不同新区发展模式下的环境压力,包括经济结构调整型发展情景(Ⅰ)、资源环境约束型发展情景(Ⅱ)和资源环境协调型发展情景(Ⅲ).以郑州新区为例开展实证研究,结合情景分析和决策者偏好,对新区规划实施所产生的社会经济发展及环境压力响应进行模拟预测.模型结果显示:新区COD排放量将由2008年的19693 t/a提高到2020年的33806 t/a.     

Semi‐Structural Forecasting of UK Inflation Based on the Hybrid New Keynesian Phillips Curve

We develop a semi‐structural model for forecasting inflation in the UK in which the New Keynesian Phillips curve (NKPC) is augmented with a time series model for marginal cost. By combining structural and time series elements we hope to reap the benefits of both approaches, namely the relatively better forecasting performance of time series models in the short run and a theory‐consistent economic interpretation of the forecast coming from the structural model. In our model we consider the hybrid version of the NKPC and use an open‐economy measure of marginal cost. The results suggest that our semi‐structural model performs better than a random‐walk forecast and most of the competing models (conventional time series models and strictly structural models) only in the short run (one quarter ahead) but it is outperformed by some of the competing models at medium and long forecast horizons (four and eight quarters ahead). In addition, the open‐economy specification of our semi‐structural model delivers more accurate forecasts than its closed‐economy alternative at all horizons.

Microstructural characterization of cobalt treated by laser surface melting under different powers

The effect of laser power outputs on microstructural evolution of cobalt(Co) treated by laser surface melting(LSM) are systematically characterized by electron channeling contrast and electron backscatter diffraction techniques equipped in scanning electron microscope. Results shows three distinctly different microstructural characteristics from surface to substrate in Co samples treated by LSM: solidification substructure(cell and cellular-dendritic) and phase transformation structure(ε martensitic plates) in the elongated columnar grains for melting zone(MZ), ε martensitic plates in insufficient recrystallization grains for heat affected zone(HAZ),and fully recrystallization microstructure for base metal(BM). Although the similarity of general evolution profiles for LSM treatment on Co under different laser power outputs, the trend of the penetration and width depth for MZ is obviously increased with increase of laser power outputs, and cellular substructure is more pronounced in the specimens treated by the higher power. The metallurgical mechanisms for LSM treatment of Co, which are closely related to the interaction between heat sources and metal, are systematically discussed in this paper.

“纽约硅谷”会攀上世界科技产业之巅吗？——兼议中国企业登临世界科技产业之巅的思考

与以往的创业公司侧重金融、证券、商业创新不同．纽约现在的创业公司也侧重发展高科技．是一种把纽约各个行业都高科技化的新创业。现在．纽约积极发展高科技．是“想拿回它原来不需要的东西”。我国一些城市的新兴公司普遍缺乏独立创新．而主要是离职人员复制、抄袭前雇主的商业模式。中国一些创业公司生态系统对新知识、新技术的推进能力较弱．尚未形成欧美式的企业独立创新模式．在未来较长一段时期内．司能较难形成国际竞争力。
