Guest Editorial

This special issue, Volume 14, Issue 2, features both new essays and reprints of pieces from past issues that are relevant to the theme of preparing teacher candidates to work effectively with families and communities. It offers each of us the opportunity to re-imagine the way we prepare our pre-service candidates for the challenges of today’s classrooms

Integrating Domains: My Work as a Christian Teacher Educator

This essay on one teacher educator’s integration of faith, learning, and scholarship articulates the author’s exploration into what it means to be a Christian teacher educator who seeks to integrate the cognitive and the spiritual domains at a small private Christian university. Drawing from both educational and spiritual literature, the essay examines both the ideals and applications of one who seeks to be a teacher educator who is informed by the life and teachings of Jesus

Logic controlled solid state switchgear

Logic controlled solid state circuit breakers and power transfer switches have been designed and built to demonstrate their use for 270 V dc power systems. This switchgear provides remote operation, automatic current level, and operates several orders of magnitude faster with much greater accuracy of response than conventional switchgear

Pneumatic separator gives quick release to heavy loads

Pneumatic separator, using applied pressure, quickly releases restraining devices securing heavy loads. With minor modifications this separator can be used as a coupling device

The Poor and Marginalized Among Us: Contingent Faculty in Jesuit Universities

Faculty of institutions of higher learning have an opportunity to discuss, debate,and discern how to create workplaces that are just and inclusive.As members of Jesuit institutions, wehave a moral obligation to do so. How, then, can Jesuit universities justify the poor treatment of contingent faculty, who are now a majority not just in our institutions but in the country as a whole? Tenure-track employment is a fading tradition in universities throughout the United States. The data also show that non-tenure-track faculty, particularly the growing number of part-time adjunct faculty, constitute a population of marginalized, often poor,employees working alongside more privileged colleagues. Furthermore, the data show that the burden of inequality falls more heavily on women and people of color. How do Jesuit values and the mission statements of Jesuit universities guide us in this situation? How do Catholic social teaching principles help us to see and articulate the current situation more clearly, and find a path to more just and equitable employment in Jesuit higher education

Take Me Out: Space and Place in Library Interactions

Information interactions are strongly affected by the place where they occur. Specific locations are ofen associated with searches on particular topics, and individual users perform different tasks in habituated places. A classic example of habituated space is the commuter who regularly reads the news on the train. This paper investigates these associations through four user studies that examine different uses of place in information interaction. Through this, we reveal the ways in which the location of information interactions makes them effective or ineffective. This extends our interpretation of the role of place in information interaction beyond established foci such as location-based search

A computer simulation of Skylab dynamics and attitude control for performance verification and operational support

A simulation of the Skylab attitude and pointing control system (APCS) is outlined and discussed. Implementation is via a large hybrid computer and includes those factors affecting system momentum management, propellant consumption, and overall vehicle performance. The important features of the flight system are discussed; the mathematical models necessary for this treatment are outlined; and the decisions involved in implementation are discussed. A brief summary of the goals and capabilities of this tool is also included

A Visit to The Kilns: A Formative Experience for Two Christian Teacher Educators

The C.S. Lewis Study Centre at the Kilns is located near Oxford, England in the previous home of C.S. Lewis, the highly influential 20th century Christian intellectual and apologist. Two professors, who coupled a brief stay at the Kilns with an inquiry into the life of Lewis and his writings, present insights into their work as teacher educators. Three main areas are explored. The first area is the nature of our work, including a discussion of the distinct roles associated with Christian teacher educators and the importance of professional community. Next is a discussion on the quality of our work, including insights into the themes of excellence and authentic learning. The third area is what we bring to our work and includes a consideration of integrity and faithfulness. The essay closes with insights from Lewis’ concept of a supposal

A model for the cost of doing a cost estimate

A model for estimating the cost required to do a cost estimate for Deep Space Network (DSN) projects that range from $0.1 to$100 million is presented. The cost of the cost estimate in thousands of dollars, C(sub E), is found to be approximately given by C(sub E) = K((C(sub p))(sup 0.35)) where C(sub p) is the cost of the project being estimated in millions of dollars and K is a constant depending on the accuracy of the estimate. For an order-of-magnitude estimate, K = 24; for a budget estimate, K = 60; and for a definitive estimate, K = 115. That is, for a specific project, the cost of doing a budget estimate is about 2.5 times as much as that for an order-of-magnitude estimate, and a definitive estimate costs about twice as much as a budget estimate. Use of this model should help provide the level of resources required for doing cost estimates and, as a result, provide insights towards more accurate estimates with less potential for cost overruns
