浅析海事行政强制中的“代履行”

目前，我国仍没有行政强制方面专门的法律规范，对行政强制的系统研究对指导工作实践具有重要意义。本文主要从海事管理机构的角度分析了行政强制执行常见的一种方式一“代履行”的定义、要件以及应遵循的原则，并提出了海事管理实践中应用“代履行”应注意的问题。     

The response of the legal system to technological innovation in aquaculture: A comparative study of mariculture legislation in California,Florida and Maine

This article examines salt‐water aquaculture (mariculture) legislation in California, Florida, and Maine, as illustrative of one generic response of the law to aquacultural innovation. Unlike aquacultural legislation in other states, generally drafted to restrict leasing of coastal waters for specific existing technologies, the legislation studied represents a more flexible approach which would accommodate new technologies. Analysis of specific provisions of the three laws indicates the complexity of the issues involved and a variety of mechanisms selected for regulating mariculture, and identifies different state priorities and goals. This report concludes that whereas broadly drafted legislation exemplified by the statutes under study is more likely to accommodate new mariculture technologies than piecemeal legislation, there are a number of complex issues that must be identified and resolved in order to achieve the desired results. The failure of each of the states to respond fully to the broad range of issues involved may inhibit aquacultural innovation or unduly restrict nonaquacultural uses of the coastal zone.     

Analysis of within-household effects and between-household differences in maintenance activity allocation

This paper investigates the allocation of household individuals to out-of-home maintenance activities using the rich activity-travel diary data from the San Francisco Bay Area. Two inter-related decisions are considered in this context: (i) whether the given activity episode is performed individually (solo) or jointly, and (ii) the person who participates in the activity, if it is a solo activity. To account for the conditional nature of the solo activity person selection, a nested mixed logit modeling framework is proposed and implemented to jointly analyze person allocation for all maintenance activities performed by a household on a given day. The model is used to investigate within-household effects and between-household differences. The proposed model relaxes some important restrictions in person allocation models by accounting for various sources of correlations and relaxing the assumption of constant variance across households. The proposed model is used to analyze the differences in person allocation between different types of households. The results indicate that life-cycle and household role, income, gender, employment status, and several types of constraints (activities including cost, time-availability, vehicle-availability, coordination constraints, and child-care obligations) affect person allocation decisions in the context of maintenance activities. The empirical results indicate the presence of various sources of correlations across persons, over activities, and within-household that are significant. In addition, the data also provides evidence that the unobserved variances in person selection utilities are not constant across households. A better understanding of these within-household interactions and between-household differences may be used in activity-based simulation models and to develop more effective and focused demand management measures.

以艉部结构为例,阐述对船体结构进行三维有限元动力分析的基本过程和关键技术。建立艉部结构三维有限元模型,使用Fluent软件计算螺旋桨脉动压力,采用Helmholtz方法计算附连水质量;为了消除局部模态的干扰,使用模态参与因子提取结构的整体模态;计算结构的固有频率、模态、速度和加速度等动力学参数。实例分析表明所采用的分析方法能够准确预报结构的振动特性。     

谈谈“行政执法一面旗”与海事文件建设

“行政执法一面旗”建设,强调依法行政,执法为民理念,体现海事行政执法先进性,是社会主义核心价值体系的重要内容,是海事系统践行“三个服务”的重要举措,是海事事业科学发展的重要保证。海事文化是海事系统在长期水上安全监督、改革发展中倡导、积累、筛选、提炼形成的思想方法、价值取向和行为习惯,是海事核心竞争力的核心要素和重要组成部分,代表了海事发展软实力。文中通过探讨“行政执法一面旗”建设和海事文化建设的内在关系,以此加深对“行政执法一面旗”深刻内涵的理解,拓宽海事文化发展思路,促进海事事业又好又快发展。
