Comparing the Recognition Memory Test and the Word Choice Test in a Mixed Clinical Sample: Are They Equivalent?

The Recognition Memory Test (RMT) was compared to the Word Choice Test (WCT) within the same fixed neuropsychological battery administered to a mixed clinical sample of 237 adults to empirically evaluate the psychometric equivalence of these two instruments. On average, there was a 3-point difference in raw scores between the two instruments (M _RMT?=?44.3, SD _RMT?=?6.8; M _WCT?=?47.1, SD _WCT?=?4.6; p?d?=?.48). The probability density functions differ substantially at the two ends of the scale but are similarly ≤42. Cross-validation analyses suggest that the RMT cutoff of ≤42 is functionally equivalent to a WCT score of ≤45.     

Innovation-related data in bureau of economic analysis international economic surveys

This paper describes innovation-related data available from international economic surveys conducted by the U.S. Bureau of Economic Analysis. These data are collected in conjunction with the international transactions accounts of the United States and in surveys of the operations of multinational companies (MNCs). The paper focuses on five innovation-related series: receipts and payments of royalties and license fees; exports and imports of research, development, and testing services; sales of services by foreign affiliates classified in the research and development services industry; MNC R&D spending; and MNC R&D employment.

Counterfactuals and Security Studies

Cause is a cognitive shorthand, not a feature of the world. Context is almost invariably critical in shaping outcomes. For both these reasons, correlations in international relations are weak and all but useless for purposes of explanation and prediction. I develop “inefficient causation” as an alternative approach to explanation and forecasting. It divides the causal problem into two components: reasons actors have for behaving as they do, and the aggregation of the behavior of multiple actors. Both make use of comparative and counterfactual analysis.     

Thucydides and Deterrence

Thucydides describes ten attempts at deterrence and compellence. With one partial exception, the use of these strategies fail and generally help to provoke the behavior they were meant to prevent. The narrative and speeches in Thucydides' text indicate that leaders everywhere rely on deterrence and compellence and expect them to succeed. Targets of these strategies nevertheless downplay risks and costs when it is contrary to their desires or needs. When motivated by appetite, actors not infrequently indulge in wishful thinking. When motivated by honor, actors are risk accepting and may welcome threats as a means of demonstrating their courage. When motivated by fear, actors worry about the consequences of compliance, which they reason may be more costly than resistance. Thucydides is the first person to frame deterrence and compellence as a strategic interaction problem and to emphasize the determining importance of motives for the strategic calculus of actors. His analysis has important implications for contemporary conflict management.
