Moving higher and higher: imitators' movements are sensitive to observed trajectories regardless of action rationality
Humans sometimes perform actions which, at least superficially, appear suboptimal to the goal they are trying to achieve. Despite being able to identify these irrational actions from an early age, humans display a curious tendency to copy them. The current study recorded participants' movements during an established imitation task and manipulated the rationality of the observed action in two ways. Participants observed videos of a model point to a series of targets with either a low, high or 'superhigh' trajectory either in the presence or absence of obstacles between her targets. The participants' task was to watch which targets the model pointed to and then point to the same targets on the table in front of them. There were no obstacles between the participants' targets. Firstly, we found that the peak height of participants' movements between their targets was sensitive to the height of the model's movements, even in the 'superhigh' condition where the model's action was rated as irrational. Secondly, participants showed obstacle priming-the peak height of participants' movements was higher after having observed the model move over obstacles to reach her targets, compared to when there were no obstacles between her targets. This suggests that participants code the environment of co-actors into their own motor programs, even when this compromises the efficiency of their own movements. We discuss the implications of our findings in terms of theories of imitation and obstacle priming
How can the study of action kinematics inform our understanding of human social interaction?
The kinematics of human actions are influenced by the social context in which they are performed. Motion-capture technology has allowed researchers to build up a detailed and complex picture of how action kinematics vary across different social contexts. Here we review three task domains-point-to-point imitation tasks, motor interference tasks and reach-to-grasp tasks-to critically evaluate how these tasks can inform our understanding of social interactions. First, we consider how actions within these task domains are performed in a non-social context, before highlighting how a plethora of social cues can perturb the baseline kinematics. We show that there is considerable overlap in the findings from these different tasks domains but also highlight the inconsistencies in the literature and the possible reasons for this. Specifically, we draw attention to the pitfalls of dealing with rich, kinematic data. As a way to avoid these pitfalls, we call for greater standardisation and clarity in the reporting of kinematic measures and suggest the field would benefit from a move towards more naturalistic tasks

Scenario-Based Comparison of Sustainable Heating and Cooling Systems for Piglet Production Systems
Industrial pig farming is a highly energy-intensive activity due to the susceptibility of extensively bred pig breeds. To ensure efficient production, optimal climatic housing conditions are necessary. In this context, reducing CO2 emissions requires maximizing efficiency in heating and cooling provision, including a significant renewable energy component. However, pig farmers face a perpetual demand to refine their production methodologies due to evolving regulatory standards and market demands. This demand influences the efficacy of existing heating and cooling strategies. To address these challenges, a comprehensive case study was undertaken at a sizable piglet farm to devise a methodology that facilitates the projection of annual heating and cooling load profiles. This methodological framework is suitable for use in similar agricultural settings with comparable operational constraints. The proactive projection of heating and cooling load profiles constitutes a foundational step in evaluating potential heating and cooling systems with regard to their energy utilization, financial viability, and carbon footprint. Central to this evaluation are the comparative analyses of heating systems such as biogas and heat pumps, alongside cooling systems exemplified by compression chillers and absorption chillers

Binary and Millisecond Pulsars at the New Millennium
We review the properties and applications of binary and millisecond pulsars.
Our knowledge of these exciting objects has greatly increased in recent years,
mainly due to successful surveys which have brought the known pulsar population
to over 1300. There are now 56 binary and millisecond pulsars in the Galactic
disk and a further 47 in globular clusters. This review is concerned primarily
with the results and spin-offs from these surveys which are of particular
interest to the relativity community.Comment: 59 pages, 26 figures, 5 tables. Accepted for publication in Living
