Adjustment,employment characteristics and intra-industry trade

Adjustment, Employment Characteristics and Intra-Industry Trade. — In this paper we use data on individual workers to investigate a number of dimensions of adjustment and relate these to trade. Specifically, we estimate the relative incidence of changes in workers’ employment status with regard to sector, firm, occupation and region. We relate the incidence of adjustment to a range of labour market characteristics and indicators of trade exposure. Our findings are not consistent with the notion that there is a systematic relationship between the type of trade expansion (inter- or intra-industry) and the type of employment adjustment (within or between industry adjustment) or that there is less labour market adjustment associated with intra- than inter-industry trade.

IPv6在计算机网络教学中应重点突出的几个知识点

IP是Internet中的关键协议。IPv6的诞生无疑是一个巨大的进步,其目的是取代现有的IPv4。目前,IPv6已经成为计算机网络技术教学中的一个重要内容。如何在教学中取得比较好的效果,本文从突出重点的角度论述了IPv4的不足之处、IPv6的优点及核心技术、IPv6与IPv4互通技术、IPv6应用新发展等几个问题。     

Aggregate scale economies, market integration, and optimal welfare state policy

Using a two-sector-two-country model with aggregate scale economies and unionisation, we show that optimal welfare state policy entails positive levels of unemployment benefits under free-trade and capital mobility. In this setting, economic integration does not reduce the revenue raising capacity of governments and thus does not lead to a race-to-the-bottom in social standards. Instead, trade and capital flows interact with welfare state policies in increasing welfare even when each government acts independently (non-cooperatively) in determining its optimal welfare payment. Cooperation is shown to improve upon non-cooperative outcomes by raising both the generosity of the welfare state and aggregate welfare.     

IPv4 to IPv6: Challenges,solutions, and lessons

Internet Protocol (IP) addresses are a crucial resource for the functioning of the Internet. Much like a telephone number, an IP address is assigned to every network interface (router, computer, mobile telephone, server, etc.) that connects to the Internet. These addresses are currently assigned using the fourth version of the Internet Protocol, or IPv4. There are a limited number of addresses that can be assigned using IPv4 and the supply of unallocated addresses is effectively exhausted. This paper (i) identifies key facts and challenges arising from IPv4 address scarcity; (ii) outlines and analyzes potential responses to IPv4 scarcity; and (iii) concludes that a decisive transition from IPv4 to IPv6 is the most durable and effective response to the exhaustion of IPv4 addresses resulting from the growth of the global Internet and the exploding demand for IP addresses.     

基于6 Sigma方法的设计成本管理体系优化——非标设备制造企业

虽然设计成本在产品成本体系中所造成的重大影响度已经成为了众多成本研究者的一个共识,但是对设计成本的研究却停留在一个比较浅显的阶段,从理论和技术上都不太成熟。本文通过6 Sigma方法对一个非标设备制造企业的设计成本体系进行研究,找出设计成本的主要影响因素并对其改善,完善设计成本体系,以达到对该公司产品成本改善的目的。

简述IPv4到IPv6的过渡

近些年来,因特网得到了飞速发展,网络在人们的日常生活和工作中起着日益重要的作用,越来越多的其他设备连接到因特网上,尤其移动通信由传统的语音通信向数据通信转化,IPv4显然已经无法满足这些要求,加之Internet IP地址分配不合理,IPv4的许多缺陷逐渐显现,其中最突出的是IP地址空间将被耗尽和主干路由表不断增长的问题,虽然NAT(网络地址翻译)等地址使用技术可以缓解IPv4地址不足的状况,但是不能从根本解决问题.所以,IPv6的推广是大势所趋.其简单描述了IPv4和IPv6之间的区别,探究了从IPv4过渡到IPv6的技术策略.
