Radiolarians of the Izu-Bonin Region

Radiolarians occur at five Leg 126 sites. Well-preserved radiolarians were recovered from Miocene and Pliocene through Holocene sections. The results of this study may help to fill the informational gap on Quaternary radiolarian distribution at mid-latitudes in the western Pacific. Radiolarian preservation is discontinuous, and, although present in Oligocene sections, specimens are poorly preserved.

Evaluation of a Change Detection Methodology by Means of Binary Thresholding Algorithms and Informational Fusion Processes

Landcover is subject to continuous changes on a wide variety of temporal and spatial scales. Those changes produce significant effects in human and natural activities. Maintaining an updated spatial database with the occurred changes allows a better monitoring of the Earth?s resources and management of the environment. Change detection (CD) techniques using images from different sensors, such as satellite imagery, aerial photographs, etc., have proven to be suitable and secure data sources from which updated information can be extracted efficiently, so that changes can also be inventoried and monitored. In this paper, a multisource CD methodology for multiresolution datasets is applied. First, different change indices are processed, then different thresholding algorithms for change/no_change are applied to these indices in order to better estimate the statistical parameters of these categories, finally the indices are integrated into a change detection multisource fusion process, which allows generating a single CD result from several combination of indices. This methodology has been applied to datasets with different spectral and spatial resolution properties. Then, the obtained results are evaluated by means of a quality control analysis, as well as with complementary graphical representations. The suggested methodology has also been proved efficiently for identifying the change detection index with the higher contribution.

How I Learned to Stop Worrying and Love the Bits: Archival Motivation in the Digital Age

Why do people become archivists? Historically (and anecdotally) it was a deep love of musty, old records that drew people to the profession. While there have been many other motivating forces that inspired would-be archivists, it is most often that one hears of people seeking jobs in archives for love of “the stuff,” as evidenced in Kate Thiemer’s blog post, Honest tips for wannabe archivists (2012). As a result of the continually advancing presence of digitized and born digital archival collections, the physical nature of archival “stuff” is changing. While there remains the physical imprint of digital information on floppy disks, CDs, DVDs, hard drives, and old computers; the aspects of these physical artifacts might not evoke the same visceral pull to the profession as musty, raspy, paper-based documents. In light of this shift in physical presentation of information, we are faced with the question: how does love of archival “stuff” translate to work in digital archives? What is and/or will be the pull to become a digital archivist? To answer these questions, we will perform a survey-based study where we will invite archivists who work with both traditional and digital archival material to answer questions related to the aspects of their work that inspired or motivated them to join the profession. What motivates people to become archivists? What aspects of digital archives do or can potentially motivate people to seek out a career as an archivist? What, if any, motivational factors for becoming a traditional archivist are the same as those for becoming a digital archivist? What, if any, motivational factors for becoming a traditional archivist are different from those for becoming a digital archivist? By answering these questions, we hope to expand the archival discussion on what it means to be an archivist in the digital age. What compelling intrinsic, evidential, or informational values are present in digital archival content that will draw professionals to the field? Are there other values inherent in digital content that are currently unexplored? In our poster, we will present our discussion of the topic, our survey design, and results we have at the time of the Institute. Thiemer, K. (2012). Honest tips for wannabe archivists.

La fraseología en la clase de lengua extranjera: ¿misión imposible?

En este artículo ofrecemos una perspectiva diferente del aprendizaje y la enseñanza de la fraseología en clase de lengua extranjera (LE). Partiendo de la premisa sobre el carácter eminentemente holístico del lenguaje, concebimos las unidades fraseológicas (UF) como elementos habituales e inherentes en la comunicación verbal, por lo que no pueden excluirse del proceso de adquisición de la competencia comunicativa en una LE. Nuestra propuesta consiste en partir de la fraseología para optimizar el desarrollo de diversas subcompetencias de la competencia comunicativa. Para ello, resulta imprescindible indagar en la configuración y el funcionamiento del significado fraseológico, que, según defendemos en este trabajo, conforma un conjunto de informaciones de diversa índole que se articulan en dos niveles, el semántico y el pragmático. Tal indagación permite desarrollar una serie de consideraciones con interesantes implicaciones didácticas.

College commons records, 1765-1829 (inclusive)

This volume, containing chronologically arranged papers mounted and bound around 1840, provides comprehensive documentation of the College commons around the turn of the 19th century. In particular, the volume documents the role the Steward played in overseeing the Commons. The records chiefly consist of the quarter reports of the Committee assigned to review the Steward’s accounts. Other documents include lists of utensils, bills for dinners for the Corporation, Overseers, and Commencement, regulations, lists of abatements for students’ quarterly bills, and information on kitchen staff.

Student accounts in commons, 1772-1778

This small volume, sewn without a backing, contains student accounts in commons, with the dates students entered and left the College.

Requests to stop commons, 1775

Requests from Tutors John Wadsworth, Caleb Gannett, and Stephen Hall to the Steward, dated March 20, March 25, and April 4, 1775, to stop the commons of students. Reasons given include illness and absence from the College.

Draft of report from Committee appointed by the Corporation to revise the Laws relating to Commons at the meeting of April 6, 1778, April 17, 1778

This report contains changes to the regulations proposed by a Committee of the Corporation at the April 6, 1778 meeting of the Corporation (these regulations can be found in the College commons records, Box 1). The proposed changes were to the articles concerning the reporting of damages to utensils by the waiters, and the requirement for the Steward to present a quarterly inventory of the utensils.

Requests for abatement of commons, November 13, 1781

Request from Tutor John Mellen (Harvard College Class of 1770) for an abatement of his commons for his absence from the College due to illness and request from Eleazer James (Harvard College Class of 1778) for an abatement of his commons due to absence from the College.

Confession of students for walking out of commons, April 1807

This document, signed by 108 students, contains a confession for their part in the 1807 student rebellion. Students were required to sign this confession in order to avoid expulsion.

Sketch of Report on Commons after said disturbance, [May 13, 1807]

Draft of a report written by a Committee of the Corporation, appointed at the meeting on April 3 "to consider the expediency of making further regulations relative to Commons."

Report of a Committee of the Corporation of Harvard College appointed “to consider the expediency of making further regulations relative to Commons,” May 19, 1807

This report expressed the opinion of the Committee that, despite the students' complaints, Commons should be not changed in any meaningful regard (save for the method of purchasing beef). Among other reasons for explaining the inflexible position of the Corporation, they stated, “alacrity, cheerfulness and docility are the companions of temperance; petulance, disquietude and perverseness are the intractable offspring of indulgence.” In addition, they suggested that students should refrain from sampling delicacies in town to better appreciate the "plain, simple, and wholesome food of the hall."
