基于Wi-Fi技术的气象装备实训平台设计

为实现对气象装备保障人员的便捷高效培训,运用无线通信技术,设计了基于Wi-Fi技术的气象装备可移动实训平台。系统通过无线通信模块将气象设备的串口协议数据转换成网络协议数据,再使用Wi-Fi无线技术将数据传输到计算机端,最后在计算机端将网络协议数据转换为串口协议数据,通过虚拟串口传送给气象应用软件,以此建立起气象设备与气象应用软件之间的无线透明传输链路,降低了布线复杂程度,提高了扩展的灵活度。实训平台采用移动式、无线通信和气象设备集中设计,解决了气象设备培训中设备种类多、布线复杂的难题,为气象设备技术保障培训提供了标准化培训环境。在对市级技术保障人员的实际培训中,验证了实训平台在实际操作中具有一定的实用性,可有效提高培训效率。此培训平台的设计为气象装备保障人员的培训提供了新的方法。

港口经济综合评价指标的因子分析

对港口经济进行综合评价需要建立一套综合评价指标体系。本文选取2008年综合竞争力排名靠前的港口作为样本,通过收集各样本在2009年的经济指标数据,利用因子分析计算出各个港口经济的综合得分和排名。结果表明所选取的指标具有高度的内在关联性,可据此有效地对港口经济情况进行评价和建议。其中,大部分港口的经济排名和货物吞吐量排名差异较小,只有南京、深圳、秦皇岛、营口和日照等港口因各自情况的不同而具有较大的差异。

Managerial technologies and power relations: a study of the Australian waterfront

In recent times, the modern port has been characterised by rapid changes in work technologies and the consolidation of logistics functions. These changes signify an important recomposition of the port labour process and raise questions about the strategic location of frontline manual jobs. This research examines how these changes have played out in the Australian ports industry, developing the argument that a depersonalised managerial form of control is emerging with potentially challenging consequences for worker solidarity and collective organisation. The argument is that relations between port management and workers have changed significantly, with a reconfiguration of job roles, skill compositions and thus workplace power relations. It is informed by qualitative research at two Australian ports, exploring the organisation of work and the impact of recent technologies.

Contractual (In)Security, Labour Regulation and Competitive Performance in the Port Transport Industry: A Contextualized Comparison of Britain and Spain

Spanish ports have traditionally been derided for poor performance and acrimonious labour relations. This situation has been reversed in recent years through a programme of reform that has (a) created a more congenial organizational ecology in which firms co-operate as well as compete; (b) ensured the collective provision of vital production inputs such as training and social peace; and (c) co-ordinated investment in new port capacity and equipment. Spanish ports now match the performance of Britain's privatized and deregulated port transport industry, where co-operation is more notable by its absence, insecurity is rife and price competition intense. Through a contextualized comparison of labour regulation in the two countries, it is possible to demonstrate that an 'institutionally saturated' and 'politically bargained' system of production and employment is compatible with, if not a necessary condition for, competitive performance in the international port transport industry.

The War on Europe’s Waterfront — Repertoires of Power in the Port Transport Industry

When the European Commission proposed a Directive On Market Access to Port Services in February 2001, the International Transport Workers’ Federation (ITF) issued a declaration of war on Europe’s waterfront. To protect established terms and conditions of employment in the port transport industry, the ITF developed a strategy of internationalization that required dock workers to engage in a new politics of scale wrought by globalization. A new repertoire of collective action — based on more effective union articulation (i.e. stronger interrelationships between the workplace, national and international levels of organization) combined with the activities of new labour networks that connected port workers at the trans‐national corporation, port range and pan‐European levels — enabled dockers to sink the Directive in the European Parliament in November 2003. The dockers’ victory will not be lost on other European unions or indeed other global union federations, although their success will doubtless prove more difficult for other occupational groups to emulate.     

Co-operation or Control? Capital Restructuring and Labour Relations on the Docks

The abolition of the National Dock Labour Scheme in July 1989 resulted in a massive restructuring of Britain's ports which in many respects has mirror-imaged that of the rest of the economy over the previous decade. In this context, the growth of small firms in the port transport industry since 1989, and in particular the emergence of workers' co-operatives, can only be explained as a process through which capital has sought to regain or strengthen control over the labour process and offset the (highly variable) costs of fluctuating labour demand. The result has been increased productivity and control for the port authorities that own Britain's ports.     

Estimating the space requirement for outbound container inventories in port container terminals

This paper proposes a method for allocating storage space to groups of outbound containers in port container terminals. For this allocation, a collection of adjacent stacks is reserved for each group of containers with the same attributes. The impacts of various space-reservation strategies on the productivity of the loading operation for outbound containers are discussed. A method is suggested for determining the size of the space requirement for outbound container yards.
