本地主机与远程主机通信故障分析

网络上应用系统的运行过程中,常会见到类似“目的主机不可到达或无法找到至目的主机的路径”的提示。对于此类问题,常可根据以下流程图的思路寻找原因。当然这只是一种总体的分析过程,并且所示的流程图也不是绝对严格的(甚至有时所出现的问题与流程图所描述的情况有出入),但这种思路对于我们缩小寻找问题的范围,避免分析问题的盲目性(有时可能无从下手),集中精力解决关

UNIX系统主机间打印机共享的实现

在几台UN压系统主机间实现打印机的共享，对于解决打印机资源不足，充分利用设备资源具有很大的现实意义。一般的UNIX系统技术资料中，只介绍本地脱机打印的设置，极少介绍打印机共享设置的问题，笔者下面介绍TCP／IP环境下UNIX主机之间的打印机共享的设置。我们使用的环境为，几台AT＆T586主机，一台OLLIVTY486主机，它们的操作系统为SCOU-NIXOPENSERThRSYSTEMV3．0．0，并且它们之间通过TCP／IP协议互连在一起，可以实现正常的通信和文件传输等。假设以其中的两台机器为例，用“＃uname－S主机名”命名，将它们的主…

大型主机配置前端处理系统的作用

为了集中大型主机系统资源，提高其联机处理和批量处理的性能，许多大型主机的用户都配置了小型机系统，为大型机作前端处理。但是把哪些处理功能放到前端处理系统之中是一个值得讨论的问题。若干年前，不少大型金融应用系统在实现24／小时对外服务的方案中，采用前端处理系统代替主机系统处理夜间联机业务，让主机在夜间集中资源完成批处理作业。这在当时也许是合适的。因为当时主机系统的处理能力、存储空间和输入输出能力都不大，批量处理作业的开销已经使主机感到压力很大，要实现24小时对外服务只能另找资源；而且当时需要提供夜间服务…

前端网点主机运行可靠性分析

长期以来,在计算机应用推广方面,大家都把主要精力投入在计算机软件开发、业务功能实现以及系统运行维护上,计算机系统的可靠性却一直被忽视。可靠性国际上通用的定义为：“在规定环境条件下和规定的时间内,完成规定功能的能力”。随着计算机技术的发展,前端系统中网点主机的可靠性已经不能满足计算机发展的要求,新一代高性能高可靠性的服务器将取代前端网点主机。

东道国的投资环境对国际直接投资的影响

本文提出一个假说——在其他条件相同的情况下,一国吸引FDI的多少与本国企业所受到的投资约束是相关的,这种约束越大,吸收的FDI就越多。本文通过FDI行业集中度的国际比较,揭示出中国FDI行业集中度极其低下的这一特殊现象,指出中国之所以能吸收如此大量的FDI,其中一个原因就是,中国企业的投资行为受到了极其严厉的金融约束和政府行为的限制。在这样的背景之下,一部分不具有任何比较优势的外资进入了中国,占领了中国市场,这对于中国经济的进一步发展是极其有害的。     

主机运行状态实时监测系统的设计与实现

随着IT产业的发展和信息化建设步伐的加快，各单位、各部门主机的数量不断增加，架构更为复杂，运维任务不断加重，能够及时了解并发现各运行主机的运行状况就显得尤为重要。系统管理员不可能做到每时每刻都对运行中的数十套主机系统的运行状态有清晰的了解，通常是由业务人员来告知系统运行存在的故障现象，这充分反映出系统运维方面的落后局面。因此，急需一套计算机辅助系统来帮助运行管理人员每天24小时监控各信息系统的运行状态，     

Effect of operating multiple affiliates on the performance of subsidiaries in the same host country

Little has been reported on the effect of affiliates on their foreign subsidiary performance. In the context of multinational banks (MNBs), we empirically investigate how the establishment of multiple affiliate forms affects the performance of their subsidiaries in the same host country. We also examine the factors influencing and effective entry mode choices. Based on the transaction cost theory, we hypothesize that MNBs can benefit foreign subsidiaries using entry modes based on cost minimization and value maximization. For the period 2005–2015, we test this hypothesis on a sample of 1026 subsidiaries established by 96 MNBs across 106 countries. The results show that the simultaneous operation of multiple affiliate forms positively influences their foreign subsidiary’s performance. The transaction costs determine MNBs’ entry choices. MNBs can enhance their subsidiary’s performance using entry modes considering institutional and cultural contexts and achieving cost and value targets in the host country. This study has policy implications in that it calls for collaboration between host and home countries to develop effective supervision and resolution regimes for MNBs operating multiple affiliate forms in host countries.     

Foreign direct investment and employment: host country experience

This study investigates the effect of foreign direct investment (FDI) on employment creation and wages in Ghana. A simultaneous panel regression model is used in estimating the effect FDI has on employment and wages. The results of this study indicate that FDI has a statistically significant and positive effect on employment levels in Ghana, but has an insignificant effect on wages. FDI can greatly augment domestic efforts by creating more jobs in the economy. The results clearly demonstrate that FDI flows affect employment quantitatively, but not necessarily qualitatively. The study identifies other factors including, productivity, wages, sub-sector, and location as important in influencing employment levels. Also, productivity, labour union, firm size, sub-sector, and location are noted as significant in affecting wages in Ghana. The main value of this paper is in respect of the fact that it provides insight into the effects of FDI flow on employment from a host country perspective. The study recommends that FDI should be considered as an integral part of the Ghanaian economic policy in order to spur on economic growth.     

How does intellectual property protection in the host country affect outward foreign direct investment?

This paper empirically analyses the impact of a host country’s intellectual property (IP) protection on Chinese outward foreign direct investment (OFDI), employing panel data of 109 host countries’ FDI stocks and IP protection levels. Based on the regression results, it is concluded that the host country’s IP protection has a significant impact on Chinese OFDI. By including an interaction term into the regression, it can be seen that a host country’s trade openness enhances the influence of intellectual property protection on OFDI. Using subsample regressions, it was found that the positive effect of the protection of IP rights by the host country on China’s OFDI is stronger in the countries along China’s ‘Belt and Road’ initiative. For a subsample of countries with a lower degree of IP protection than China, the positive effect of IP protection is weaker than in ones with a higher IP protection level. The results obtained through a threshold regression, show that host countries can be divided into three categories, based on gross domestic product per capita, namely low, medium and high development levels. The higher the level of economic development of the host country, the greater the impact of IP protection on China’s OFDI. The host countries are also categorised into low-, medium- and high-level IP protection levels. As the level of a host country’s IP protection improves, it promotes OFDI from China.

Foreign bank subsidiaries’ risk-taking behavior: Impact of home and host country national culture

This paper examines whether the risk-taking behavior of foreign affiliates of multinational banks is more influenced by the national culture of their parent banks’ home country or the national culture of foreign affiliates’ host country. The study uses a dataset of 292 foreign affiliates (i.e., subsidiaries or branch operations) operating in 66 countries having parent banks in 26 countries for empirical analysis. National culture of both home and host countries is measured with four dimensions—uncertainty avoidance, individualism, masculinity and power distance—of Hofstede's framework of national culture. Findings suggest that the national culture of parent banks’ home country has higher impact on the risk-taking behavior of foreign affiliates of multinational banks than the national culture of their host country. Specifically, foreign affiliates’ risk-taking is higher if parent banks’ home country has low uncertainty avoidance, high individualism and low power distance cultural values. This study extends our understanding that how informal institutions, such as the national culture, influence the financial decisions in multinational banks.
