Why McNemar's Procedure Needs to be Included in the Business Statistics Curriculum

In business research situations it is often of interest to examine the differences in the responses in repeated measurements of the same subjects or from among matched or paired subjects. A simple and useful procedure for comparing differences between proportions in two related samples was devised by McNemar (1947) nearly 60 years ago. Although the technique has enjoyed widespread usage in both behavioral and medical research, it has unfortunately not received proper attention in marketing, advertising, consumer research, public relations, operations management, or organizational behavior endeavors—disciplines wherein it is particularly desirable to evaluate the significance of changes in attitudes, opinions, or beliefs regarding some campaign or strategy. Perhaps the major reason for this obscurity is simply a general lack of awareness as to its value and practical power. The McNemar test is generally not currently being taught to business statistics students. It is the purpose of this article to demonstrate the usefulness and applicability of the McNemar procedure to these aforementioned disciplines so that it may be more appropriately employed as an important confirmatory data analysis tool within the basic business statistics curriculum.

我国舆论监督立法现状的考察分析和设想

我国有关全国舆论监督的法律规定散诸在宪法、法律、法规和规章之中．但这些规定是不全面、不完备、不统一的，为了落实好依法治国的方略．建设好社会主义政治文明．必须充分发挥舆论监督的功能。因此必须使舆论监督有全面的宪法依据、彻底的刑法保护，尤其是要有专门法律——《舆论监督法》的支持和规范。

从张闻天到邓小平:"生产关系的两重性"的提出和实践

20世纪60年代,张闻天通过对近十年社会主义建设探索中失误的反省,结合对马克思主义理论的精细研究,提出了“生产关系的两重性”的理论创见;而邓小平对待资本主义的态度、发展社会主义市场经济思想与这一理论创见表现出惊人的趋同。可以说,前者是后者的理论先导。

The disaggregated technology production function: A new model of university and corporate research

Technology and the process that produces it, research and development (R&D), are typically characterized as homogeneous entities. In reality, the typical industrial technology is composed of three elements: a generic technology base, supporting infratechnologies, and proprietary market applications (innovations). The first two have public good characteristics, and therefore, explicitly modeling them is essential for public policy purposes. The fundamental relationships among these elements require a technology production function that captures the supporting roles of the public good elements in creating proprietary applied technology. These critical quasi-public technology goods are supplied to a significant extent by exogenous (external) sources: central corporate research labs, government labs, and increasingly, universities. The expanding university role beyond basic research complicates the structure and functioning of the national R&D establishment and increases the need for a more accurate model of technological change to better inform R&D policy.Moreover, in assessing the resulting applied technology's impact on economic growth, both the general and partial equilibrium literatures enter the technology variable into a production function with the common “production” assets (physical capital and labor). Such models obscure an important distinction between technology and these production assets—namely, the fact that technology is primarily a “demand-shifting” asset. As such, its role is correctly specified only when combined with the other major demand-shifting asset, marketing. Allocations to these two assets vary across competing firms implying a spatial model of competition, while still providing traceability to the exogenous sources of public good technology elements, such as universities.
