Presidential Address: Theory, Research, Practice, Caring, and Spirituality: Zen and the Art of Educational Administration

Educational theory should be the foundation for most practice and research, but this is not a one-way relationship. Good inductive research may help to develop theory instead of coming from it. The relationship of theory to research can be different in qualitative research than in quantitative research. Practice can and should also inform and be informed by theory and research. Theory, research, and practice are very important to the field of education, as is the nexus of these constructs. The author of this paper considers the nexus of theory, research, and practice and delves deeper into these constructs to suggest a foundational nature of caring and spirituality

Relation of the Motor Nerve Endings to Voluntary Muscle in the Frog

This is a subject upon which most authorities differ widely, and few, if any, agree upon all points entirely. It is therefore, an inviting field tor research. Because of the extreme diversity of opinions current it has seemed best to me to formulate them in a brief way before giving the results of my own observations

Productivity Differences between Male and Female Managed Farms in the Eastern and Central Highlands of Kenya

This study was carried out in an agroforestry farming system in the central highlands of Kenya. The purpose of the study was to compare the productivity and technical efficiency of male and female managed farms. The study also sought to investigate the sources of differences in the Total Value Product and the technical efficiency of farms. Using a female dummy, the study found no evidence of differences in total value product between male and female managed farms. Male managed farms were however more technically efficient than female managed farms. The highest proportion of farms in the lowest bracket of efficiency levels was female managed farms. The total value product was found to be positively affected by age of the farmer, female labour and inputs while it was negatively affected by land size.Farm Management, Labor and Human Capital,

Formation of rings in galactic discs by infalling small companions

We use N-body simulations to study the formation of rings in a disc galaxy by the impact of a small spherical companion. Both barred and nonbarred target discs are considered. We discuss the effect of the properties of the target disc (distribution of mass in the disc, velocity dispersion, etc.) as well as of the mass and orbit of the companion on the properties of the rings, such as their amplitude, width, shape, expansion velocity and lifetime. In particular the amplitude, width, lifetime and expansion velocity of the first ring increase considerably with companion mass, and so does the expansion velocity of the particles in it and the total extent of the disc after the interaction. We also discuss the formation and evolution of spokes and show that they can be caused by companions of relatively small mass. In our three examples of oblique impacts on barred target galaxies we note important transient displacements of the bar, as well as changes of its pattern speed and size. An asymmetric pseudoring is formed in each case, and during the first stages of its evolution the bar forms part of it.Comment: 21 pages Latex, 22 figures, of which 7 as separate gif-files.

Is attending a mental process?

The nature of attention has been the topic of a lively research programme in psychology for over a century. But there is widespread agreement that none of the theories on offer manage to fully capture the nature of attention. Recently, philosophers have become interested in the debate again after a prolonged period of neglect. This paper contributes to the project of explaining the nature of attention. It starts off by critically examining Christopher Mole’s prominent “adverbial” account of attention, which traces the failure of extant psychological theories to their assumption that attending is a kind of process. It then defends an alternative, process-based view of the metaphysics of attention, on which attention is understood as an activity and not, as psychologists seem to implicitly assume, an accomplishment. The entrenched distinction between accomplishments and activities is shown to shed new light on the metaphysics of attention. It also provides a novel diagnosis of the empirical state of play

A Qualitative Follow up of the Maguire Fellows Program

This qualitative follow up sought the impressions of students after a two year program. The analysis of this data involved grounded theory qualitative methods. The primary means of data collection for the qualitative portion of this study was through digitally-recording and transcribing of participants’ voices in response to individual interview prompts. Seven themes emerged from the first interviews which included 1). Perceptions of leadership, 2). Changing perceptions the Jesuit ideas Magis/cura personalis, 3). Changing perceptions of social justice, 4). Perceptions of Motivation or desire to lead, 5). Catholic identification, 6). Theory to practice, and 7). Suggested changes to the program. These themes were reinforced and refined in the second interviews, but a few new themes emerged from the additional data. Specifically, the value of the cohort was strongly expanded in the data from the second interviews. Other new themes included special education, the action research project and some systems issues
