On this point, all of them, not only ICT professionals but also non-professionals or end-users, need to accept responsibility to the public and to have professional spirit in order to make and keep the information society and e-business environment safe and reliable. However, an individual ICT worker is not necessarily a strong existence; he or she is in a complex situation filled with stress and pressure and his or her decisions are sometimes affected by it. Therefore, social and organisational measures to prompt ICT workers to behave in professional spirit are necessary to be taken.展开更多

In this paper, based on the structure characteristics and XRD data, the crystal habit of BaY2F8 was analyzed. The strong bond in crystal structure of BaYEF8 was Y-FE-Y, which stretched to the shape of chain along the direction of [001]. And this was an advantaged direction for the crystal growth. The steady shapes of BaY2F8 were composed of rhombic prism { 130} and {021 }. The crystal showed an axial habit in the direction of [001]. The analysis of the crystal slice obtained by temperature gradient technique verified the above conclusion. The BaY2F8 crystal was grown by compulsive methods such as Czochralski method.展开更多

Whereas the tremendous development of information and communication technology (ICT) has made it easier for firms to acquire, store, share, and utilise personal data on their customers, firms that use personal data are exposed to risks related to privacy issues. Since individuals fear the invasion of their privacy, the failure of a firm to appear or remain trustworthy would make it difficult for it to maintain accurate, up-to-date databases and to construct desirable business processes, which would affect the bottom line. Therefore, modern firms should do what they can to ensure that their customers trust them. For them, one promising way to remain trustworthy is to behave as a moral agent. Although it is difficult for any firm to meet the conditions necessary to be a moral agent, competence in behaving as a moral agent is a hard-to-imitate capability af firms for which personal data use is vital for enjoying the benefits of business relationships in the e-business environment.展开更多

The purpose of this research is to help enhance a decision support for three distribution center locations with different ranges of area in order that the distributors are able to serve appropriately the retailers in twelve large cities or capitals of the nine countries in Asia-Pacific region. The researcher applies the theory of supply chain and logistics management systems with Excel, Visual Basic and Genetic Algorithms programs to find the research results. The research results revealed that the interfaces of Excel, Visual Basic, and Genetic Algorithms programs helped decision support in distribution range selection for 3 distribution center locations. Each of which had different ranges of area for distribution with a rapidly, flexibly distributed time. However, variables resulting in a decision-making should be adjusted under certain circumstances for more reliable, specific needs.展开更多

文摘This paper empirically examined the impact of fiscal policy on inflation in Nigeria.Time series data on inflation,government revenue,government expenditure,and gross domestic product were sourced from the Central Bank of Nigeria(CBN).The aforementioned secondary data cover the period from 1981 to 2021.The Augmented Dickey Fuller(ADF)unit root test and Johansen co-integration test were used to testing for data stationarity and the existence or otherwise of co-integrating equations respectively.Thereafter,data were analyzed using Ordinary Least Square and Parsimonious Error Correction techniques.Findings from the study show that government expenditure and revenue both have a positive relationship with the rate of inflation,though the latter is not statistically significant.Also,there is a positive but insignificant relationship between inflation and gross domestic product.In line with the above findings,we,therefore,recommend that the Nigerian government at all levels(local,state,and federal)should be tactful in the use of fiscal policy tools to avoid triggering inflationary pressure and its negative multiplier effects on the welfare of its citizenry.

Each of which had different ranges of area for distribution with a rapidly, flexibly distributed time. However, variables resulting in a decision-making should be adjusted under certain circumstances for more reliable, specific needs.
文摘Using cross section data of 3 years 2000,2007,and 2014 for non-financial listed firms in China,this study quantitatively analyzes the relationship between government-affiliated corporate executives and corporate performance.We classify the sample firms into two groups,based on whether their chief executive officers(CEOs)and independent directors are prior government officials or not.Then,we empirically examine the difference in corporate performance between the two groups.We find that the appointment of CEOs and directors of listed companies in China is significantly affected by government shareholders.The results also suggest that prior to 2000 government-affiliated CEOs impaired corporate performance.But with the establishment of State-owned Assets Supervision and Administration Committee and the completion of the Split-Share Structure Reform in 2006,government as a shareholder began to give priority to corporate value maximization,and government-affiliated CEOs began to help improve corporate performance.However,due to the slowdown of economic growth after 2012,problems such as inefficiency and corruption brought by government-affiliated executives manifested again,and therefore,corporate performance deteriorated.Meanwhile,government-affiliated independent directors have limited influence on these factors.

文摘This paper studies the connection between the stock market and real output in China and compares it with benchmark countries,employing a novel vector autoregression with asymmetric leads(VARwAL)model.It makes two contributions.First,it finds that the time profile of the Chinese stock market's response to real output shocks suggests no evidence of a distorted relationship due to manipulation of Chinese real output data or domination of the Chinese stock market by individual investors.Rather,the Chinese stock market is relatively more responsive to real output,in line with the larger share of manufacturing in the Chinese economy.Electricity output and industrial profits,two different,less-manipulable time series,yield similar results.Second,it presents the first use of VARwAL impulse responses to detect stock market bubbles:VARwAL captures the 2015 bubble in China successfully.Over the full sample period,China's stock market appears to have been less prone to bubbles than the US stock market.

文摘Irrigation infrastructure expansion threatens the diversity of freshwater fish worldwide.Irrigation infrastructure creates migration barriers which can block access to important nursery,feeding and spawning habitat.Lao PDR is a landlocked country situated within the Lower Mekong River Basin where there is a substantial dependency on rice and fish for food,income and livelihoods.The country is experiencing an unprecedented boom in irrigation infrastructure investment,with modernisation programs being implemented in every province.Despite significant investment in infrastructure upgrades,and the potential impact on freshwater fish,little consideration has been given to fish passage solutions.In 2008,we commenced a fish passage program in Lao PDR.The intent of this case study is to outline the pivotal elements of the program of knowledge development and transfer,in the context of river connectivity and fisheries management in Lao PDR.We also highlight challenges in international research in development and lessons learned.
