项目教学法在计算机组网技术中的探索

在社会进入信息化时代的今天，计算机技术的应用在社会覆盖面之广，为软、硬件及网络维护人员提供了广阔的就业空间，特别是把“软件蓝领”的培养定位在中职教育后，既为中专计算机专业的发展提供了良好的机遇，亦对我们的教学质量提出了更高的要求。在组网技术课程的教学过程中，笔者发现继续沿用“以教师为中心”的传统教学模式和方法，已很难达到教学要求。在教学中引入项目教学法后，以局域网组建为项目，通过讲授该项目的实施过程，使学生具备网络组建和维护的基本技能，大大提升了教学质量，取得了极好的教学效果。

An ethical defense of cryptocurrencies

The growing importance of the cryptocurrency phenomenon has raised concerns about the ethical implications of a hypothetical widespread use of these new forms of digital money. In this paper, we undertake an ethical assessment of cryptocurrencies drawing upon two specific ethical theories: private property ethics and utilitarianism. Particularly, we focus on three distinctive aspects. First, we examine the advantages and disadvantages of cryptocurrencies vis-à-vis central bank fiat money. Second, we analyze cryptocurrencies as facilitators of tax evasion and the ethical implications arising therefrom. Finally, we explore the use of cryptocurrencies for nefarious consumption. We conclude that, were cryptocurrencies to become widespread media of exchange, governments capacity to undertake monetary, fiscal, and drug policy would be undermined. We argue that this would be an ethically desirable outcome from both a private-property-rights and a utilitarian perspective since it would force governments to reduce their size and scope in these three areas.     

In defense of social responsibility

The purpose of the present article is to argue against the minimalist theory of social responsibility (i.e., that the sole responsibility of business is to maximize profit in conformity with law), particularly as it is advanced by Butler D. Shaffer. Against this view, I argue that such a theory does not necessarily support or achieve greater levels of corporate efficiency than does a more demanding theory of social responsibility, and that the argument for the former view is no more valueneutral than for the latter. Finally, I argue that Shaffer fails to show that the more maximal theory demands too much from executives and is too unclear to be applicable to their decision-making.     

In defense of social responsibility

Recent journalistic criticism of the concept of corporate social responsibility rests on the assertion that social responsibility adds nothing to corporate profits. Hence, inclusion of the motion in the business vocabulary amounts to nothing more than “double talk.”The author of an influential 1953 book on the topic took another look at social responsibility twenty-five years later and found “few gains in the quality of business stewardship over that time.” The idea “remains peripheral to the mainstream of economic thought.”Corporate social responsibility involves more than simply being a law-abiding corporate citizen. It reaches into these decision-making areas where perfectly legal choices may have harmful social consequences. As evidence of social harm amounts, society has to define and defend the ground on which it requires an appropriate response from the business corporation. Society will get the response it demands.     

A defense of employee rights

Recent trends in business ethics along with growing attacks upon unions, suggest that employee rights will be a major social concern for business managers during the next decade. However, in most of the discussions of employee rights to date, the very meaning and legitimacy of such rights are often uncritically taken for granted. In this paper, we develop an account of employee rights and defend this conception against what we take to be the strongest in-principle objections to it. Joseph R.
