Career development for women in maritime industry: organisation and socialisation perspectives

For centuries, the maritime industry has been a recognised place in society dominated solely by men, and even though there were women involved, they were mostly on the periphery. This research aims to fill the gap of women’s career development in this field, by investigating the relationships among the degree of organisational socialisation, women’s workplace culture, and the career development of women in the maritime workplace. The analyses are conducted with the structural equation model with 202 valid questionnaires. The results indicated that women’s workplace culture has a significantly negative relationship with the degree of organisational socialisation, and then in turn, it has a significantly positive relationship with women’s career development in the maritime industry. Finally, the results also indicate that the mediating effect of organisational socialisation existed between women’s workplace culture and women’s career development. According to the empirical analysis, this study makes conclusions as well as suggestions for the maritime enterprises as the reference for human resource management.     

A new method for absolute datum transfer in seafloor control network measurement

To decrease the time consumption and the labor intensity in the absolute datum transfer of traditional seafloor control network measurement, a new method, namely sailing-circle positioning method, is put forward in this paper. First, the traditional intersection positioning model is improved by considering the equivalent sound velocity profile error as an unknown parameter in the adjustment model. Second, the effect of geometric dilution of precision (GDOP) on positioning accuracy is analyzed. By seeking for the minimum of GDOP, it is concluded that the absolute datum transfer can achieve the highest accuracy in the condition of sailing along a circle relative to other sailing paths. Moreover, the optimal radius of the circle for the accurate datum transfer is also given out. Besides, the correlation between the accuracy of datum transfer and the sound velocity error in this method is analyzed. Finally, the new method was tested and verified by the experiments in Songhua lake with the water depth of 60 m and in South China sea with the water depth of 2000 m, respectively. These experiment results show that the new method can improve the accuracy and efficiency of traditional datum transfer method significantly.

浙江与韩国铁路的比较研究

浙江与韩国在土地面积、 人口数量、 资源禀赋以及区位条件等多个方面都十分相似， 两者具有很强的可比性。 同时， 两者在经济发展水平以及铁路发展水平等方面也表现出了一定的差距。 文章以铁路运输为切入点， 分别回顾和总结了浙江和韩国两地的铁路发展历程和铁路运输现状。 在充分比较和分析两地铁路发展水平的基础上， 提出了韩国铁路发展对浙江的几点启示： 首先， 浙江应进一步扩大铁路网规模和密度； 其次， 浙江铁路将继续发挥对经济发展的拉动作用， 但随着时间推移拉动效应逐渐减弱； 最后， 浙江应积极探索和制定更为灵活多样的票制票价， 以吸引更多群体类型的旅客选择铁路出行。     

CT reconstruction with priori MRI images through multi-group datasets expansion

Computed tomography (CT) reconstruction with a well-registered priori magnetic resonance imaging (MRI) image can improve reconstruction results with low-dose CT, because well-registered CT and MRI images have similar structures. However, in clinical settings, the CT image of patients does not always match the priori MRI image because of breathing and movement of patients during CT scanning. To improve the image quality in this case, multi-group datasets expansion is proposed in this paper. In our method, multi-group CT-MRI datasets are formed by expanding CT-MRI datasets. These expanded datasets can also be used by most existing CT-MRI algorithms and improve the reconstructed image quality when the CT image of a patient is not registered with the priori MRI image. In the experiments, we evaluate the performance of the algorithm by using multi-group CT-MRI datasets in several unregistered situations. Experiments show that when the CT and priori MRI images are not registered, the reconstruction results of using multi-group dataset expansion are better than those obtained without using the expansion.

压密注浆在市政道路高填方路基处理设计中的应用探析

某市北环路工程处于平原地区,地质条件相对较好,有利于工程建设,但由于是新城区,分布有较多沟塘。该工程为水泥混凝土路面,属于刚性路面,对路基的不均匀沉降较为敏感,处理不好这些沟塘,就会产生不均匀沉降,影响道路的使用效果和寿命。压密注浆工艺近年来在建设工程领域应用较广,但还没有完整的理论体系,在公路和市政工程中的应用目前也是处在探索阶段。该工程通过方案比选最终采用了压密注浆工艺对高填方路基进行了加固处理,取得了良好的效果。
