专注芯片将给AMD带来优势

2005年,英特尔公司一直向外界传递一个信息:我们关注PC超过仅仅关注处理器。实际上, 英特尔公司将很多芯片集成到一个系统中来提供单个用户所需的所有功能。英特尔公司将处理器和其它芯片捆绑提供的方法称为“平台化”。     

ON THE DISTRIBUTIONAL CONSEQUENCES OF CHILD LABOR LEGISLATION*

This article studies the effects of child labor legislation on human capital accumulation and the distribution of wealth and welfare. We calibrate our model to U.S. data circa 1880 and find that the consequences of restricting child labor or providing tax‐financed education depend on the main source of individual household income. Households with significant financial assets unambiguously lose from government intervention, whereas high‐wage workers benefit most from a child labor ban, and low‐wage workers benefit most from free education. Introducing free education results in substantial welfare gains, whereas a child labor ban induces small welfare losses.     

Rhonda M. Williams: Competition, race, agency, and community

As the United States approaches the twenty-first century… in an information-based, transnational and managerial economy, it is becoming increasingly apparent that if we do not better negotiate race and ethnicity in our society, we will not adequately solve the problems of economic inequality and discrimination. Racial and/or ethnic divisions and competition shape our efforts to understand and challenge hierarchy and inequity. As long as we ignore those issues, we cannot solve the problems of poverty, unemployment, and crime, nor effect productive job creation and economic justice. Absent a cultural and economic reckoning with racism’s legacies, we will fail to revitalize our cities and to recover from the socioeconomic costs of “ending welfare as we knew it.” Although masked behind pronouncements of a “color-blind” society, unfinished racial business weakens our national will to provide one another the portfolio of social and economic rights essential to the sustenance of humane community in the post-industrial global economy.

Voluntary Disclosures as a Mechanism for Defining Entity Status in Australian Not‐for‐Profit Organisations

This study examines managerial efforts to portray an entity's not‐for‐profit (NFP) status based on voluntary disclosure practices. The annual report text of 61 NFPs are analysed in accordance with Salamon and Anheier's (1997) NFP definitional framework. Results indicate a predominant application of the structural‐operational definition. Furthermore, the ‘organised’ attribute of this definition prevails over the ‘non‐profit‐distributing’ criterion that has been advocated by various parties. Standard‐setting bodies may want to consider: (1) NFP management perspectives in any revised NFP definition; and (2) greater clarity in conceptual framework and standard‐setting arrangements to improve overall transparency in NFP reporting practices.     

CEO optimism and forced turnover

We show theoretically that optimism can lead a risk-averse Chief Executive Officer (CEO) to choose the first-best investment level that maximizes shareholder value. Optimism below (above) the interior optimum leads the CEO to underinvest (overinvest). Hence, if boards of directors act in the interests of shareholders, CEOs with relatively low or high optimism face a higher probability of forced turnover than moderately optimistic CEOs face. Using a large sample of turnovers, we find strong empirical support for this prediction. The results are consistent with the view that there is an interior optimum level of managerial optimism that maximizes firm value.     

Principles for Economic Recovery and Renewal

Over the past year, substantial progress has been made on the path to economic recovery. Yet, as true with most recessions induced by a financial crisis, recovery is going to be long and slow. This is particularly true for employment. Moreover, there is evidence that indicates there are structural as well as cyclical concerns about this recovery's slow employment growth. The personal as well as macroeconomic costs of this slow growth mean that there is no higher public policy priority than economic recovery and job creation. This address presents and discusses three guiding principles for economic policy: restoring confidence, increasing aggregate demand, and achieving broader and deeper education.     

Examining the influence of different levels of sexual-stimuli intensity by gender on advertising effectiveness

Abstract

Sexual appeals grab attention and elicit emotional responses, yet the existing literature surrounding this area of research has yielded inconsistent findings with regard to their ability to influence consumer liking and preference. Little attention has also been given to investigating sexual appeals beyond the scope of the effects of gratuitous sexual stimuli (nudity), and as such, most of what is known about sexual appeal advertising is centred on the effects of nudity alone. The current study examines sexual-stimuli intensity (explicit vs. mild) in print advertising and assesses its influence on advertising effectiveness and how this varies by gender for Australian consumers. An experiment is conducted as a test of the hypothesised relationships, with findings indicating that the level of sexual-stimuli intensity in print advertising is more effective in influencing consumers’ attitudinal and behavioural responses when depicted at a mild intensity level than at an explicit intensity level. These findings offer important insights for marketers in the design and configuration of sexual appeals used in advertising to maximise the effectiveness of ads to achieve favourable consumer behaviour outcomes.     

Taking a Moment to Teach Engineering Economy

The acquisition of knowledge can be facilitated when previous knowledge or experience can be applied to the learning process. This article describes an approach for teaching engineering economy that utilizes knowledge from previous courses, statics and mechanics of materials, to improve learning. The concept of moments from these engineering mechanics courses was adapted and used to explain the concept of equivalence in engineering economy. Initial results after one semester indicated less time required for learning the concepts without adverse effects on student exam scores. Results after four semesters show higher course grades with the mechanics-based approach as well as improved student attitudes and higher teaching evaluations.
