Metadata And Minerals : A Library – Museum Pilot Project, Christine Baker Apr 2019

Metadata And Minerals : A Library – Museum Pilot Project, Christine Baker

Digital Initiatives Symposium

The Arthur Lakes Library and the Geology Museum at Colorado School of Mines (Mines) worked together to explore ways to promote the Museum’s unique collections. A task force formed to conduct a pilot project that involved creating digital access, via Mines Institutional Repository, to a set of the Museum’s mineral specimens from Creede Mining District. The Metadata Librarian collaborated with the Museum Collections Manager throughout this process to establish metadata requirements and workflows. This presentation explains how the pilot project came about and describes the preparation, metadata and workflow development, as well as the collaborative experience and evolution ...

1995 - Monterey County Water Conservation Alternatives - An Analysis Feb 2019

1995 - Monterey County Water Conservation Alternatives - An Analysis

Monterey County Water Resources Agency Engineering Reports

The major goal of this study ,prepared by Agland Investment Services, Inc. on behalf of the Monterey County Water Resources Agency, was to estimate the direct and regional economic impacts of different policies aimed at encouraging agricultural water conservation in the Salinas Valley. The study also looked at combinations of conservation measures which could provide a least cost conservation contribution to the seawater intrusion problem. Agland concluded that policymakers should consider adopting a least cost approach when they considered the mix of infrastructure projects and urban and rural conservation measures.


Finding Teaching Inspiration From Gorgias: Mathematics Lessons From A Sophist, Ann L. Von Mehren Jan 2019

Finding Teaching Inspiration From Gorgias: Mathematics Lessons From A Sophist, Ann L. Von Mehren

Journal of Humanistic Mathematics

The logos or rational language of the fifth-century BCE teacher, Gorgias, as contained in the fragment On the Nonexistent, challenges a reader to understand the relationship between the existent and the nonexistent; yet the text also offers an accessible idea of logos. Inspired by William M. Priestley's approach to the study of logos through ratios, and by Ivor Grattan-Guinness's recommendation to broaden the study of historical texts in the history of mathematics and mathematics education, and pursue their significance in a heritage sense, this article suggests that this ancient non-mathematics text by Gorgias may inspire and refresh elementary ...


Fun With Math On Valentine's Day, Kristin T. Kennedy Jan 2019

Fun With Math On Valentine's Day, Kristin T. Kennedy

Journal of Humanistic Mathematics

This article describes various love-themed activities the department of mathematics at Bryant University hosted during a college-wide celebration of love called "The Arts and Science of Love", held during Valentine's Day 2018. Inspired by Susan D'Agustino's article "To Fall in Love with Math, Do This" [1], Bryant mathematicians came up with many creative and engaging activities that brought mathematics and its practitioners closer to the students on campus. Much fun was had.


What Is Humanistic Stem And Why Do We Need It?, Debra T. Bourdeau, Beverly L. Wood Jan 2019

What Is Humanistic Stem And Why Do We Need It?, Debra T. Bourdeau, Beverly L. Wood

Journal of Humanistic Mathematics

Getting students who are planning on technical careers to value their general education courses, particularly in the humanities, is not an easy task. The experiences of two professors from disciplines that cross the so-called divide between STEM and Humanities motivate not only a series of courses blending the two to the advantage of their own students but also a virtual pedagogical community to support efforts taking place elsewhere.


Symmetry And Measuring: Ways To Teach The Foundations Of Mathematics Inspired By Yupiaq Elders, Jerry Lipka, Barbara Adams, Monica Wong, David Koester, Karen Francois Jan 2019

Symmetry And Measuring: Ways To Teach The Foundations Of Mathematics Inspired By Yupiaq Elders, Jerry Lipka, Barbara Adams, Monica Wong, David Koester, Karen Francois

Journal of Humanistic Mathematics

Evident in human prehistory and across immense cultural variation in human activities, symmetry has been perceived and utilized as an integrative and guiding principle. In our long-term collaborative work with Indigenous Knowledge holders, particularly Yupiaq Eskimos of Alaska and Carolinian Islanders in Micronesia, we were struck by the centrality of symmetry and measuring as a comparison-of-quantities, and the practical and conceptual role of qukaq [center] and ayagneq [a place to begin]. They applied fundamental mathematical principles associated with symmetry and measuring in their everyday activities and in making artifacts. Inspired by their example, this paper explores the question: Could symmetry ...


The Mathematics Orientation Seminar: A Tool For Diversity And Retention In The First Year Of College, Salvatore J. Petrilli Jan 2019

The Mathematics Orientation Seminar: A Tool For Diversity And Retention In The First Year Of College, Salvatore J. Petrilli

Journal of Humanistic Mathematics

In this article I describe Adelphi University's Mathematics Orientation Seminar, a new course that was introduced into the mathematics major to help students find their passion in mathematics and to strengthen the educational community within our department. I discuss quantitative and qualitative results of surveys among students in the Mathematics Orientation Seminar in Fall 2016 and Fall 2017, which suggest that this might be a useful course for other institutions to utilize within any major. Finally, I explore faculty perspectives and describe what I believe to be the final version of this course.

1913 - Water Resources Of California, Part Iii, Water-Supply Paper 300 Jan 2019

1913 - Water Resources Of California, Part Iii, Water-Supply Paper 300

Miscellaneous Documents and Reports

The water available for irrigation and domestic supply was the chief factor in the development of southern California, which then had a population of more than 1,000,000 people. The many mountain streams of California afforded abundant hydroelectric power, the utilization of which in manufacturing enterprises and in transportation had been made possible by the progress of electric-power transmission during the previous decade.

Information concerning the quantity of water carried by the streams had been and would continue to be an important factor in the development of these resources, for the fundamental importance of stream-flow data was so thoroughly ...


1920 - Irrigation Of Twelve Million Acres In The Valley Of California; Robert Bradford Marshall Jan 2019

1920 - Irrigation Of Twelve Million Acres In The Valley Of California; Robert Bradford Marshall

Miscellaneous Documents and Reports

By 1920, California's potential wealth in land reached into billions of dollars; 12,000,000 acres of available agricultural lands remained practically untouched. Marshall proposed a large plan that would make the Valley of California the world's greatest garden. The engineering plans for such a project must be comprehensive, for their execution must not only assure the complete reclamation of 12,000,000 acres of valley lands but must also effectively and forever control the river floods and insure safe and continuous river navigation throughout the year. The hydro-electric current generated along most of the streams would furnish ...

1921 - Petroleum Resources Of California, Bulletin 89

Miscellaneous Documents and Reports

By 1921, the increasing demand for petroleum and its products, and the inability of production to keep pace with requirements, for several years, resulted in widespread prospecting throughout the world for possible new oil fields. In California, "wild-cat" wells were being drilled in many localities, some of them in places where even a cursory inspection of the geology would tell the futility of looking for oil. This report aimed to furnish information as to the unfavorable as well as the favorable areas of development of additional petroleum resources in California. The purpose of the report was to briefly take stock ...
