Unlocking the mysteries of the past: Searching for clues in medieval manuscripts
No full textThis project looks at the reproduction of one mid-12th-century Roman text by analyzing sixteen versions of it that still exist, copied from c. 1160 through c. 1325. The author was Nicolaus Maniacutius, a cleric at St. John Lateran Basilica in Rome. That original copy is lost, but versions quickly appeared in monasteries and cathedrals in Italy, Germany, France, and England. Somehow, through networks of communication and travel, reproductions were made and collected by prominent monasteries and churches, and by the Guildhall, a secular institution in the City of London
Natural Resources Research Institute Map
No full textThis map (NRRI/MAP-2002/02) is the outcome of eight field days mapping and sampling in the area by the senior author. The initial
impetus for this mapping was to try to define Duluth Complex induced contact-metamorphic zonation in the footwall Giants Range
batholith, and to relate this to Cu-rich mineralization in these rocks. Research into footwall Cu-rich mineralization continues, and will be
published in the future. However, the discovery of large expanses of Cu-Ni mineralized rock in the basal zone of the South Kawishiwi, in
an essentially unmapped area, lead to this preliminary map (Figure 1). The geologic map represents the initial interpretaton of the bedrock
geology of the basal zone of the South Kawishiwi Intrusion, based on mapped outcrops, subcrops, and glacial materials (float). In addition,
geologic units intersected in drill holes have been projected updip to the surface. The faults depicted on the map are interpreted from
aeromagnetic data, steepening of the dip of the basal contact of the Duluth Complex, and topographic lineaments. The location and
simplified regional geology encompassing the map area is depicted in Figure 4.
The lithologic legend of the geology map is simplified into the intrusive stratigraphy of the South Kawishiwi Intrusion first defined
by Severson (1994). Readers interested in detailed descriptions of the regional South Kawishiwi Intrusion stratigraphy are referred to
that work. Cu-Ni-PGE mineralization is largely confined to the basal stratigraphic units of the intrusion (units BAN, BH, and U3), and
on the ground is largely represented by knob-like outcrops, and large expanses of rusty, gossaneous boulder fields (subcrops). Old test pit
dumps (circa 1890 ?) into the Biwabik Iron Formation are common in the southern portion of the map, and occur in areas of anomalous
magnetic field properties.
Seventy-five rock samples (Figure 2) were collected in the area (described in Table 1), and Dr. Philip Brown and John Marma
(Department of Geology, University of Wisconsin - Madison) provided the funding for the base- and precious-metal analyses of
twenty of these samples (presented in Table 2). Check assays for anomalous samples were analyzed by ALS Chemex labs from the original
pulps and rejects (Table 2). Assay data for the majority of the drill holes in the map area have been compiled by Peterson (1997), which
includes > 60,000 geochemical analyses for drill holes throughout the Duluth Complex.
The smaller-scale property position map (Figure 3) depicts the current mineral lease holders in the area, and should only be viewed as
a "snapshot" of the mineral land positions at the date of this map. Detailed geologic mapping in the area, including additional geochemical
analyses, has been approved from the Permanent University Trust Fund, and will be completed during the 2002 field season.Peterson, Dean M; Marma, John; Brown, Philip. (2002).

Natural Resources Research Institute Map
No full textThis map is the first of what is hoped (contingent on funding) to be a series of new detailed bedrock geology maps of the marginal
zone of the South Kawishiwi Intrusion by the University of Minnesota Duluth's Natural Resources Research Institute (see Peterson,
2006). Such mapping will form the basis for continued exploration for Cu-Ni-PGE mineralization as well create the geologic base
upon which environmental review associated with exploitation of such mineralization can be built.
Recent detailed mapping at a scale of 1:5,000 by the authors was conducted west and south of the Boundary Waters Canoe Area
Wilderness (BWCAW). Nearly 1,000 outcrops along approximately 100 kilometers of field traverses were examined to identify and
confirm the internal lithologic variability, contact relationships, and structure of the Nickel Lake Macrodike between the BWCAW
and Omaday Lake. The authors wish to acknowledge Dr. Paul Weiblen (emeritus professor of geology at the University of
Minnesota) for his keen insight of the geology of the area and Dr. George Hudak and undergraduate student Jeremiah Gowey of the
University of Wisconsin Oshkosh for assistance in mapping outcrops around and south of Omaday Lake. Additional reconnaissance
mapping in early November by the senior author was conducted to field check compiled outcrop locations depicted on the 1957
INCO map of the Spruce Road Deposit and the 1968 Hanna Mining map of the South Filson Creek Deposit (both of which are
publically available in the DNR archive at Hibbing, Minnesota). The reconnaissance mapping confirmed the location of gossaneous
Cu-Ni bearing INCO outcrops and reconfirmed the outstanding field mapping of all types of Duluth Complex rocks by Hanna
Mining Company geologists of the late 1960s (see figure of "Sources of Information").
This map has been built upon (in the areas surrounding depicted outcrops and historic drill holes) the 1966 map of the Gabbro Lake
15' quadrangle by Green et al. (Minnesota Geological Survey Miscellaneous Map M-2), which because of its quality has been the
geologic foundation for this area for 40 years. The reader of this map should compare the author's interpretation of the bedrock
geology to that depicted on M-2, which will undoubtedly highlight the need for continued detailed mapping of the marginal zone
of the South Kawishiwi Intrusion (which was not the purpose of map M-2), especially in light of the greatly increased interest in the
potential for exploiting the vast resources of Cu-Ni-PGE mineralization enclosed within these rocks. The Nickel Lake Macrodike is
lithologically and structurally related to the South Kawishiwi Intrusion and the known Cu-Ni-PGE deposits of Birch Lake, Maturi,
Maturi Extension, Spruce Road, and South Filson Creek.
The citation for this map includes the caveat "Version 1", which points out the fact that the authors believe that more detailed
geologic mapping and analytical studies (no petrography or geochemical analyses of recently collected samples has been
completed) are needed to truly understand what the bedrock geology enclosed within the boundaries of this map sheet (and the
area to the west-southwest) really is (ie. we've only begun to scratch the surface). This map and all associated GIS data (in ArcView

A genetic variation map for chicken with 2.8 million single-nucleotide polymorphisms
No full textWe describe a genetic variation map for the chicken genome containing 2.8 million single-nucleotide polymorphisms (SNPs). This map is based on a comparison of the sequences of three domestic chicken breeds (a broiler, a layer and a Chinese silkie) with that of their wild ancestor, red jungle fowl. Subsequent experiments indicate that at least 90% of the variant sites are true SNPs, and at least 70% are common SNPs that segregate in many domestic breeds. Mean nucleotide diversity is about five SNPs per kilobase for almost every possible comparison between red jungle fowl and domestic lines, between two different domestic lines, and within domestic lines--in contrast to the notion that domestic animals are highly inbred relative to their wild ancestors. In fact, most of the SNPs originated before domestication, and there is little evidence of selective sweeps for adaptive alleles on length scales greater than 100 kilobases
A Connectionist and Multivariate Approach to Science Maps: Som, Clustering and Mds Applied to Library & Information Science Research.
No full textThe visualization of scientific field structures is a classic of scientometric studies. This paper presents a domain analysis of the library and information science discipline based on author co-citation analysis (ACA) and journal cocitation analysis (JCA). The techniques used for map construction are the self-organizing map (SOM) neural
algorithm, Ward’s clustering method and multidimensional
scaling (MDS). The results of this study are compared with
similar research developed by Howard White and Katherine
McCain [1]. The methodologies used allow us to confirm that
the subject domains identified in this paper are, as well,
present in our study for the corresponding period. The appearance of studies pertaining to library science reveals
the relationship of this realm with information science.
Especially significant is the presence of the management on the journal maps. From a methodological standpoint, meanwhile, we would agree with those authors who consider
MDS, the SOM and clustering as complementary methods
that provide representations of the same reality from different analytical points of view. Even so, the MDS representation is the one offering greater possibilities for the structural representation of the clusters in a set of variables

Digital Story Map Learning for STEM Disciplines
No full textModern technological advances and trends require new pedagogy and delivery of mapping materials to prepare the future workforce in the disciplines of Science, Technology, Engineering, and Mathematics (STEM) for an increasingly technology-dominated society. The purpose of this study was to develop an Environmental Systems Research Institute (ESRI) Story Map “Soil Forming Factors: Climate„ for multiple STEM disciplines based on the design guidelines from the Cognitive Theory of Multimedia Learning (CTML). The study incorporated a two-group post-test only design that utilized multiple methods of analysis, including a quality assessment of the ESRI Story Map using the five principles of effective storytelling, direct quantitative measures of learning (quiz), and surveys of participants’ perceptions (PowerPoint presentation versus ESRI Story Map) using QualtricsTM. Survey results were summarized by gender, academic classification (year), and academic major program. The newly developed ESRI Story Map was an effective teaching tool as demonstrated by quiz scores and students’ positive responses. Post-testing scores indicated that ESRI Story Maps were an effective way to learn and were viewed as effective as traditional teaching methods (e.g., PowerPoint). Additionally, students reported feeling comfortable using ESRI Story Maps. These positive responses were consistent by gender, major, and academic classification (year). This research indicates that adding audio may improve the use of this ESRI Story Map for educational concept delivery. Empirical studies such as this that include multifaceted quantitative and qualitative assessments are critical to understanding the benefits of new types of multimedia learning in an educational setting
The (unknown) role of map librarian and the challenge of satisfying the cartographic user needs

The profession of librarianship is developed and is being recognized in Sri Lanka. But we have neither heard of a map library nor a map librarian in our local environment. In Europe and USA map libraries are well known and map librarians are recognized
Librarians who deal with maps come under the special library group and have to manage the map collection in a special manner. It needs specialized knowledge in managing map collection. Reading of maps needs technical equipments and storage and preservation too is different from books. Hence the librarian who deals with maps should undergo training to familiarize himself/herself with the technical methods of storage, search co ordination and manage archives and enhance access of cartographic materials.
After world War 11 traditional map depositories are converted into cartographic centres and new technology is heavily used in map production, storage and usage. This paper highlights the role to be played by map librarians in a modern library using new technologies.
Map users are very much advanced in using different type of technologies in reading, creating, copying etc.maps. This technological advancement has not caused much change in map collection in the developing countries. Even in the 21st century we see the traditional collection of maps in Sri Lanka.
.
While studying the situation (advance collection and advance users) in other countries, a sample study was carried out with reference to the local environment by selecting academic and special library groups. This paper elucidates the role played by a librarian who handle maps, who is not recognized as a map librarian It also discuses the attitudes of the cartographic users towards map libraries in our country the institutions where map collections are available, the barriers experienced by the users in accessing the collections, important issues neglected by the higher authorities and lack of a national body to authorize map production in the country.
The role that could be played by the national body or a regulatory body such as management of collection and databases, setting of standards, copyright law and implementing a national policy in map production and the problems faced in producing maps are discussed.
The study reveals that the gap between the traditional map libraries (collection) and the users of cartographic material is widening. The author suggests that the librarians could overcome this problem by undergoing professional training. This will change the attitude of the users towards the map librarians and map libraries. This will give recognition to the professionals who work as map librarians

Patchwork E-Dialogues in the professional development of new teachers
No full textBook chapter in "Technology supported learning and teaching: a staff perspective." Edited by John O'Donoghue, 2006In this chapter the authors contend that the encouragement of reflective writing within professional learning programmes is not new. They suggest that electronic technologies, however, afford exciting opportunities to develop this practice to support participative and collaborative learning beyond barriers of time and place. This chapter explores the value of asynchronous dialogue in creating and sustaining communities of practice, with particular emphasis on the role of the e-mentor
