This research examines how the cost performance of defense contracts varies among the Air Force, Army, Navy, and the Department of Defense (DoD) and among five major defense contractors: Boeing, Lockheed Martin, Northrop Grumman, Raytheon, and General Dynamics. Data for these analyses was extracted from the recently established Defense Acquisition Management Information Retrieval (DAMIR) web-based interface for management information on Major Defense Acquisition Programs (MDAP). Note that, in addition to the three military services, MDAP data is also reported for DoD itself.

Data analysis indicates that the Navy ranks last among the military services and DoD in cost performance for MDAP contracts, while the Air Force ranks best. Of the defense contractors, Raytheon ranks last in cost performance and General Dynamics is next to last. Furthermore, the Navy contracts more frequently with Raytheon and General Dynamics than do the other services or DoD. Explanatory factors for poor cost performance may be due to factors such as the Navy's lack of oversight, the quality of the acquisition workforce, the defense contractors’ cost inefficiency, ethical lapses, or weak corporate governance, or combinations of these factors.

In addition, the schedule performance data was also identified. Tests of statistical significance on the schedule performance difference generally yield no results except for one relationship which indicates that the Navy is more likely to have Acquisition Program Baseline (APB) schedule breaches than its counterparts. Finally, cost performance data is examined for statistically significant differences between the two major categories of defense contracts: fixed-price contracts and cost-plus contracts. However, no significant findings were discovered.

We use student-level online resource usage data for students in four different introductory accounting courses to explore the impact on exam performance of both student study effort and students’ revealed preferences for reading text or watching video lectures. The online learning tool tracks student study choice (read text, watch video, or skip) on a paragraph-by-paragraph level. We match these usage data with student performance on course exams. We find that students who study more material earn higher exam scores than do students who study less material. We also find that students who self-select to do relatively more of their studying through reading text score higher on exams, on average, than do students who self-select to do relatively more of their studying through watching videos. Specifically, holding the overall amount of study constant, a student who chooses to spend the highest fraction of her or his study time watching video mini lectures earns exam scores 10 percentage points lower (six-tenths of a standard deviation) than a student who chooses to spend the lowest fraction of study time watching videos. Our results demonstrate that at least for introductory accounting students, increased study effort does indeed have a positive impact on exam performance. Our evidence also suggests that the highest performing introductory accounting students choose to learn accounting proportionately more through reading than through watching. These results are a reminder that when we talk about using “technology” to help our students learn accounting, the written word is still an important technology.

Wages have been spreading out across workers over time – or in other words, the 90th/50th wage ratio has risen over time. A key question is, has the productivity distribution also spread out across worker skill levels over time? Using our calculations of productivity by skill level for the United States, we show that the distributions of both wages and productivity have spread out over time, as the right tail lengthens for both. We add Organization for Economic Co-Operation and Development (OECD) countries, showing that the wage–productivity correlation exists, such that gains in aggregate productivity, or GDP per person, have resulted in higher wages for workers at the top and bottom of the wage distribution. However, across countries, those workers in the upper-income ranks have seen their wages rise the most over time. The most likely international factor explaining these wage increases is the skill-biased technological change of the digital revolution. The new artificial intelligence (AI) revolution that has just begun seems to be having similar skill-biased effects on wages. But this current AI, called “supervised learning,” is relatively similar to past technological change. The AI of the distant future will be “unsupervised learning,” and it could eventually have an effect on the jobs of the most highly skilled.

Early in one’s career in psychology, certainly starting in graduate school, if not sooner as a psych major in college, a choice point gradually emerges between seeking a career as a scholar, a scientist, and perhaps as an academic versus pursuing the life of a practitioner, one who applies the work of the former, the scholar. We faculty will often cast this choice in the form of a “tension” between science and practice. Ironically, I have never felt such tension. The purpose of this chapter is to explore choices we make in life and career, the consequences of these choices, and what we can learn in the process, that is, along the way and the implications for organization change and development.

The chapter will address comparative teacher preparation programs for teachers who wish to teach in inclusive settings, including those in the United States and People’s Republic of China. Consideration will be given to developing course objectives and outcomes for teacher preparation programs through the alignment of teacher standards and content standards. Further, discussion will review assessing pre-service teacher candidates for inclusive settings. It will conclude with recommendations for inclusive teacher preparation programs.

This study examines an issue that confronts most instructors in the first financial accounting course at the postsecondary level, that is, some students have had a high school accounting course, while others have not. Specifically, this study investigates the effect a high school accounting course has on student performance in their first postsecondary level financial accounting course (midterm examinations and course grades). The results suggest this relationship is significant and positive, yet must be interpreted carefully. For example, scholastic aptitude, time management skills, and other intrinsic values also play an important role in student achievement.
