Exploring Engineering

Engineering faculty members at Bucknell University have established a course required for freshman engineering students and open to liberal arts students. The course has been designed to stimulate and enhance student interest in all the engineering disciplines at Bucknell. The course ranges broadly across small groups, faculty-lead recitations, laboratory experiences, student design projects, traditional lectures, and guest speakers. The exploring engineering course has completed its second year. The authors describe the course, the changes made since the initial offering and the impact on the students and faculty involved. They also present and interpret student evaluations of the course.(4 refs)

Changes in hemodynamics and tissue oxygenation saturation in the brain and skeletal muscle induced by speech therapy - a near-infrared spectroscopy study

Arts speech therapy (AST) is a therapeutic method within complementary medicine and has been practiced for decades for various medical conditions. It comprises listening and the recitation of different forms of speech exercises under the guidance of a licensed speech therapist. The aim of our study was to noninvasively investigate whether different types of recitation influence hemodynamics and oxygenation in the brain and skeletal leg muscle using near-infrared spectroscopy (NIRS). Seventeen healthy volunteers (eight men and nine women, mean age ± standard deviation 35.6 ± 12.7 years) were enrolled in the study. Each subject was measured three times on different days with the different types of recitation: hexameter, alliteration, and prose verse. Before, during, and after recitation, relative concentration changes of oxyhemoglobin (Δ[O2Hb]), deoxyhemoglobin (Δ[HHb]), total hemoglobin (Δ[tHb]), and tissue oxygenation saturation (StO2) were measured in the brain and skeletal leg muscle using a NIRS device. The study was performed with a randomized crossover design. Significant concentration changes were found during recitation of all verses, with mainly a decrease in Δ[O2Hb] and ΔStO2 in the brain, and an increase in Δ[O2Hb] and Δ[tHb] in the leg muscle during recitation. After the recitations, significant changes were mainly increases of Δ[HHb] and Δ[tHb] in the calf muscle. The Mayer wave spectral power (MWP) was also significantly affected, i.e., mainly the MWP of the Δ[O2Hb] and Δ[tHb] increased in the brain during recitation of hexameter and prose verse. The changes in MWP were also significantly different between hexameter and alliteration, and hexameter and prose. Possible physiological explanations for these changes are discussed. A probable reason is a different effect of recitations on the sympathetic nervous system. In conclusion, these changes show that AST has relevant effects on the hemodynamics and oxygenation of the brain and muscle.

[Draft of a committee report, 1790]

Two folio-sized leaves containing a handwritten draft of a report of a committee explaining proposed changes to the academic schedule of Harvard undergraduates. The report discusses the rearrangement of lectures, exercises, disputations, and recitations and the specific reasoning behind the changes. The first page of the report is written on the verso of an essay by student Henry Daingerfield titled, "Wishing of all employments is the worst," and the second page of the report is written on the verso of an essay on the importance of teaching morals to the young by Bradstreet Story (later known as Dudley Story Bradstreet, Harvard AB 1792), dated 1790.

Interleaved almanac, 1743

The 1743 diary is interleaved in Nathaniel Ames’ An Astronomical Diary, or, An almanack for the year of our Lord Christ, 1743. The thin paper-covered book holds brief notes about Holyoke’s daily life as an undergraduate, written on blank pages bound with the almanac. The pages of the diary are separated into two columns: the first to display symbols indicating when class recitations occurred, and the second for entries. Entries include information about student life, Harvard events such as Overseers’ meetings and individuals who preached and lectured, trips to Boston and surrounding towns, and occasional references to community deaths and illnesses.
