ObjectiveIn this study we used functional magnetic resonance imaging to investigate whether motor imagery of handwriting and circle drawing activates a similar handwriting network as writing and drawing itself.MethodsEighteen healthy right-handed participants wrote the German word “Wellen” and drew continuously circles in a sitting and lying position to capture kinematic handwriting parameters such as velocity, pressure and regularity of hand movements. Afterward, they performed the same tasks during fMRI in a MI and an executed condition.ResultsThe kinematic analysis revealed a general (...) correlation of handwriting parameters during sitting and lying except of pen pressure during drawing. Writing compared to imagined writing was accompanied by an increased activity of the ipsilateral cerebellum and the contralateral sensorimotor cortex. Executed compared to imagined drawing revealed elevated activity of a fronto–parieto-temporal network. By contrasting writing and drawing directly, executed writing induced an enhanced activation of the left somatosensory and premotor area. The comparison of the MI of these tasks revealed a higher involvement of occipital activation during imagined writing.ConclusionThe kinematic results pointed to a high comparability of writing in a vertical and horizontal position. Overall, we observed highly overlapping cortical activity except of a higher involvement of motor control areas during motor execution. The sparse difference between writing and drawing can be explained by highly automatized writing in healthy individuals. (shrink)

Recovering Reason: Essays in Honor of Thomas L. Pangle is a collection of essays composed by students and friends of Thomas L. Pangle to honor his seminal work and outstanding guidance in the study of political philosophy. These essays examine both Socrates' and modern political philosophers' attempts to answer the question of the right life for human beings, as those attempts are introduced and elaborated in the work of thinkers from Homer and Thucydides to Nietzsche and Charles Taylor.

A common finding is that information order influences belief revision (e.g., Hogarth & Einhorn, 1992). We tested personal experience as a possible mitigator. In three experiments participants experienced the probabilistic relationship between pieces of information and object category through a series of trials where they assigned objects (planes) into one of two possible categories (hostile or commercial), given two sequentially presented pieces of probabilistic information (route and ID), and then they had to indicate their belief about the object category before (...) feedback. The results generally confirm the predictions from the Hogarth and Einhorn model. Participants showed a recency effect in their belief revision. Extending previous model evaluations the results indicate that the model predictions also hold for classification decisions, and for pieces of information that vary in their diagnostic values. Personal experience does not appear to prevent order effects in classification decisions based on sequentially presented pieces of information and in belief revision. (shrink)

An earlier version of this paper was presented at the 2011 IEEE International Symposium on Technology and Society at Saint Xavier University in Chicago, Illinois. This paper examines factors in college student confidence in using electronic books as learning tools between 2007 and 2009. The study was done in response to the growing concern over the cost of textbooks and the increase in the use of e-textbooks to counteract that cost. This study shows that despite a lack of a gap (...) between comfort of use of computers, students whose parents income is above the national median income are more confident in learning from electronic books than students whose parents income is not. Not only is this gap existent but it widened between 2007 and 2009 despite the growing confidence in the use of electronic books by both groups. The results of this study suggests that this gap, and its concomitant widening, could be associated with exposure to computer classes in high school and the choice of major. (shrink)

Colleges of agriculture are being forced to adapt to a changing world. The forces behind these changes affect all departments within the college. In this paper, the place of agricultural economics within the college and within the university is identified, the current situation facing the discipline is outlined, and strategies for responding to the forces of change are discussed. Three alternatives are available: continuation, termination, and metamorphosis. Different departments are likely to pursue different strategies. Some may disappear altogether or may (...) be absorbed into the parent discipline, economics, or into the business school. Other departments may transform themselves into specialized sub-disciplines, such as natural resources or agribusiness departments. Still others may continue with little or no change. Whatever course is followed, strategic planning will surely be necessary. (shrink)

"The Traffic in Culture takes us along exciting new avenues in the investigation of art and society, global encounter, and the marketing of culture. These essays will become required reading to scholars in fields as diverse as art history, anthropology, sociology, and cultural studies."--Suzanne Preston Blier, Harvard University "These essays break new ground in charting out a critical ethnography of art. They address the complexities of cultural difference while ceasing to respect the boundary between 'Western' and 'non-Western' art which has (...) defined the scope of the anthropology of art for too long. This is contemporary critical anthropology at its best."--Nicholas Thomas, Australian National University. (shrink)

The authors examined the effects of ethical leadership on follower organizational citizenship behavior (OCB) and deviant behavior. Drawing upon research related to the behavioral plasticity hypothesis, the authors examined a moderating role of follower self-esteem in these relationships. Results from a field study revealed that ethical leadership is positively related to follower OCB and negatively related to deviance. We found that these relationships are moderated by followers' self-esteem, such that the relationships between ethical leadership and OCB as well as between (...) ethical leadership and deviant behavior are weaker when followers' self-esteem is high than low. Implications of these findings for research and practice are discussed. (shrink)
