Framing the Nexus of Globalisation,Logistics and Manufacturing in Europe

Abstract

Under the ongoing influence of globalisation, supply chains have changed significantly. New logistics and manufacturing systems have emerged, causing longer transport distances and increasing transport emissions. The existing research into the sustainability impacts of freight transport has largely viewed it as being a macro-level economic and political phenomenon and has ignored the interdependencies amongst micro-level economic actors, including firms and businesses in the private sector. In this paper, we presume that the lack of conceptualisation of freight transport in relation to wider institutional contexts and firm behaviour results in the lack of a holistic approach to understanding freight governance in the face of globalisation. We argue for the use of institutional economic geography lenses to elucidate the distribution networks of emerging logistics and manufacturing practices and its implications for freight transport. We illustrate our argument through a broad look at the European logistics and manufacturing practices and global production.

基于欧洲规范的结合梁截面可靠度校验

以可靠度指标β=4．7为目标，研究结合梁截面在承载能力极限状态下应该具有的安全系数；并对根据欧洲规范EC4(Euro code 4)设计的结合梁截面进行可靠度校验，获得结合梁截面实际具有的安全系数，比较二者，认为在现行EC4分项安全系数的基础上需要一个附加安全系数，这样才能保证所设计的结合梁截面达到欧洲规范ECI(Euro code 1)要求的可靠度．     

Seasonal and short spatial patterns in European hake (Merluccius merluccius L.) recruitment process at the Balearic Islands (western Mediterranean): The role of environment on distribution and condition

This study evaluates the link between the recruitment process of European hake (Merluccius merluccius L.) of the Balearic Islands (western Mediterranean) and the environmental and physiological conditions. Spatio-temporal variation of abundance and condition of fish were evaluated at two locations each with different oceanographic conditions, one in the north (Sóller, SO) and another in the south (Cabrera, CA) of Mallorca Island. Environmental variables explored were hydrography, sediment characteristics, phytoplankton pigment concentration (ppc) and the trophic resources of hake. Individuals were divided in three life stages: recruits, post-recruits and young adults. Hepatosomatic index (HSI), relative condition index (K_n), gonadosomatic index (GSI) and fullness index (FI) were analysed for the three life stages. Recruitment starts in February with the incorporation of smaller hakes, and it can be followed through spring and early summer with a peak in April. However, some spatial heterogeneity in the recruitment process has been found between north and south of the Island. The main pulse of recruitment occurred at a different time in the two areas. Spatial heterogeneity was also consistent with the condition of hake recruits, with higher values of K_n and HSI at SO than at CA. Maximum values of K_n were found in February at SO and in April at CA, coinciding with the start of the different recruitment pulses to the fishing grounds. Post-recruits and young adults also showed higher condition at SO than at CA. The arrival in spring of the Western Winter Intermediate Waters (WIW) drives the spatial-temporal variation in abundance and condition of hake. Ppc was highly correlated with recruit abundance with a time lag of two months, while for post-recruits the time lag was three months. The observed differences in the condition of hake between areas could be a consequence of the fact that the waters to the north of Mallorca are comparatively more under the seasonal influence of WIW which is formed in more productive areas. Thus, this study characterises the short temporal and spatial variability in the hake recruitment process off the Balearic Islands, both in terms of abundance and fish condition. This pattern is explained on the basis of the mesoscale environmental variability observed between north and south of Mallorca and the ecological adaptive strategy of recruiting in the optimal environmental season.
