Review of the Lightning Strike Incident at Launch Complex 37 on July 27, 1967, and Comparison to a Gemini Lightning Strike

The Launch Complex 37 lightning strike of July 27, 1967, was reviewed and compared to a similar incident on the Gemini Program. Available data indicate little likelihood of damaging currents having been present in SA-204 Launch Vehicle or the ground equipment during the July 27th incident. Based on the results of subsystem and system testing after the strike, anticipated results of future testing, the six months elapsed time between the strike-and launch, and the fact that much of the critical airborne electrical/electronic equipment has been removed since the strike for other reasons, no new actions are considered necessary at this time in the Gemini case, significant failures occurred in both airborne and ground circuits. Due to the resultant semi, condlictor uncertainty, and the relatively' short time prior to planned launch, all critical airborne components containing semiconduetors were replaced, and a sophisticated data comparison task was implemented

Adding Resistances and Capacitances in Introductory Electricity

We propose a unified approach to addition of resistors and capacitors such that the formulae are always simply additive. This approach has the advantage of being consistent with the intuition of the students. To demonstrate our point of view, we re-work some well-known end-of-the-chapter textbook problems and propose some additional new problems.Comment: 13 pages, LaTeX, uses additional packages, 7 eps figures; one comment added after the truncated-cone resisto

Problematising the pursuit of progress in mathematics education

In this article, I use a Foucauldian poststructural analysis to examine productions of progress within key discursive spaces of mathematics education. These sites of production are educational policy, mathematics education research and case studies of primary school student-teachers in England. From my analysis, I show how progress governs what is possible in the classroom, as they become constructed around a measurable, linear temporality assumed in educational policy. This encourages comparison to and pursuit of the “normal” mathematical child, which in educational policy is produced as a functional automaton, whilst for much of mathematics education research is produced as the cognitive “natural” child. These over sanitised constructions result in confusion for student-teachers who struggle to take these impossible discourses on board

Finding First-Year Success in Extension: Navigating Stakeholder Needs and Institutional Expectations

Functioning within a defined administrative framework and meeting the needs of the stakeholders are essential in an Extension appointment. The first day of employment starts the promotion and tenure clock. It is the responsibility of the new Extension professional to take immediate steps to move forward with development of programming and application of the skill set that they bring to the job. Finding success in the first year of an Extension appointment revolves around understanding the expectations of the institution and the needs of the stakeholders. Once the institutional expectations and programming needs are understood, formulating a strategy that includes plans of work and logic models, measurement of outcomes and impacts, team building, professional development, peer mentoring, grant writing, and scholarship will provide a foundation for firstyear success in Extension. A willingness to follow a timely and systematic approach to meeting the expectations of the institution and stakeholders will provide for an efficient transition and relieve many of the stressors associated with a new appointment. This paper is based primarily on the author’s first year experience as an Extension faculty member and summarizes several best practices

Lies, defeasibility and morality-in-action : the interactional architecture of false claims in sales, telemarketing and debt collection work

Lying is known to be endemic in a range of business settings. However, to date studies have not analysed how lies surface, and are spontaneously managed, in ‘real time’ interaction. Drawing on video and audio recordings, in this paper we analyse how actors account for false claims produced in different settings, namely sales, telemarketing and debt collection. Drawing on resources from ethnomethodology and conversation analysis, lies are conceptualised as products of interactional organization, rather than, say, products of the mind or motives of social actors. Our analysis reveals the centrality of ‘epistemics’ for understanding how people handle, and seek to neutralise, the moral risks associated with false claims. Potential accusations of ‘lying’ are shown to be defeasible in light of claims that the speaker has ‘discovered’, ‘noticed’ or ‘remembered’ some pertinent detail. We recover practices through which false claims are transformed, with varying degrees of success, from nefarious to innocent accountings. We conclude by discussing the implications of our findings for wider questions about the reproduction of work cultures that rely upon deceit
