The forthcoming UK ban on stall and tether housing for sows will result in an increase in the use of group housing for these animals. In group housing systems, certain individuals may be particularly aggressive or bullied by others, and this may result in injury or socially induced stress. To attempt to overcome these problems we need to know the answers to questions such as whether removal of a particularly aggressive animal from a group will result in a general decrease in aggression, or whether it will simply result in other animals becoming more aggressive. Answers to these sorts of question require a fundamental understanding of pig social behaviour and individual characteristics. For example, is aggressivness a stable individual characteristic across time and situation? This research addressed these issues by examining the cross-time consistency of individual aggressiveness and social status in groups of pigs.

Abstract We present a method for identifying up- and downstream industries in inter-industry datasets via input–output tables. We apply this approach to aggregated European input–output data and present results on identified industry links and their sensitivity to threshold definitions. We furthermore test the time-consistency of the up- and downstream assignments based on input–output tables, and discuss the limitations of this method. Finally, the method is used to test anti-competitive effects of non-controlling minority shareholdings.

Abstract Background Development of cognitive skills for competent medical practice is a goal of residency education. Cognitive skills must be developed for many different clinical situations. Innovation We developed the Resident Cognitive Skills Documentation (CogDoc) as a method for capturing faculty members' real-time assessment of residents' cognitive performance while they precepted them in a family medicine office. The tool captures 3 dimensions of cognitive skills: medical knowledge, understanding, and its application. This article describes CogDoc development, our experience with its use, and its reliability and feasibility. Methods After development and pilot-testing, we introduced the CogDoc at a single training site, collecting all completed forms for 14 months to determine completion rate, competence development over time, consistency among preceptors, and resident use of the data. Results Thirty-eight faculty members completed 5021 CogDoc forms, documenting 29% of all patient visits by 33 residents. Competency was documented in all entrustable professional activities. Competence was statistically different among residents of different years of training for all 3 dimensions and progressively increased within all residency classes over time. Reliability scores were high: 0.9204 for the medical knowledge domain, 0.9405 for understanding, and 0.9414 for application. Almost every resident reported accessing the individual forms or summaries documenting their performance. Conclusions The CogDoc approach allows for ongoing assessment and documentation of resident competence, and, when compiled over time, depicts a comprehensive assessment of residents' cognitive development and ability to make decisions in ambulatory medicine. This approach meets criteria for an acceptable tool for assessing cognitive skills.

The global financial crisis of 2007–2009 has changed the landscape for monetary policy. Many central banks in developed economies had to employ various unconventional policy tools to overcome a liquidity trap. These included large-scale asset purchase programs, forward guidance and negative interest rate policies. While recently, some central banks were able to return to conventional monetary policy, for many countries the effectiveness of unconventional policies remains an issue. In this paper we assess diverse practices of unconventional monetary policy with a particular focus on expectations and time consistency. The principal aspect of successful policy in terms of overcoming a liquidity trap is the confidence that interest rates will remain low for a prolonged period. However, forming such expectations faces the problem of time inconsistency of optimal policy. We discuss some directions to solve this problem.
