Abstract: Writing an academic paper may seem like hiking up an unfamiliar mountain without a trail map. The total effort is immense, you don’t know the area, and you may not feel fit enough to handle the stress. There is also a maze of trails: some trails are interesting, some tiresome and some simply leading nowhere. Where should you start, how should you start, and is it possible to leave your own mark?

Here are a few motivational techniques and ideas to get you climbing…

Woods & Leibovitz (2005) ESL- Common Problems (Presentation)Abstract: To encourage ESL students in their writing by showing them that many of the writing problems they experience are in fact experienced by many native writers as well. To collaborate with the students to come up with some solutions which may help them respond to these problems in future writing assignments. All of this should be interactive with very little ‘lecture style’ teaching.

GemIdent – The Gem Identification Domain Expert

GemIdent is a gem identification software and data base used in gemology.It should not be confused with a similarly named image recognition program. GemIdent is derived off MinIdent.

GemIdent represents information about gems in a statistical manner and identifies unknown gems with a fuzzy-like matching system.

People. GemIdent was developed between 1989 and 1990 by David Pierre Leibovitz and Heideh Omoumi.

The MinIdent database: some recent development

Smith, D. G. W., Omoumi, H., & Leibovitz, D. P. (1989) The MinIdent database: some recent development. 28th International Geological Congress. Extended Abstract, 3: 138-139. [doi: 10.13140/RG.2.1.5092.7842] (pdf)

MinIdent-PCAbstract: The MinIdent database and the software for mineral identification (Smith &: Leibovitz 1984, 1986; Smith, 1986) have been successfully ported to a PC from the Amdahl mainframe on which they were developed. The “compiled” data base (used in mineral identification) plus necessary management programs can be accommodated on a 30 Mbyte hard disc. Developments presently being undertaken, will further reduce these storage requirements.

Since the publication by Smith &: Leibovitz (1986). many new data have been added and information now exists for some 4.200 mineral varieties. species. series. groups etc. Literature and data-entry errors are being identified using tests for self-consistency. and progressively eliminated.

In particular. that part of the database dealing with un-named minerals has been greatly expanded, and reorganised by year of first description. Data for un-named minerals are presently scattered throughout 100 years of earth science literature and range from vague descriptions of hand-specimen properties to complete modern analyses. The lists compiled by Hey (1962. 1963) were made the starting point. and then a wide range of journal and other literature sources used to obtain additional information and to bring the list up to date. Only those minerals for which numerical data are available have been included. Presently. nearly 600 un-named minerals appearing in the literature have been included. Once complete, this subset of the database will provide a unique resource and will allow users attempting to identify unknowns to compare their data with those for all previously described minerals and not only with those species that have received names. The use of the mineral identification software permits a numerical estimate to be obtained of the similarity between an unknown and previously described species. The immediate availability of a compilation of literature data for the latter provides a convenient indication of what other parameters might be obtained for a more unambiguous identification. The possibility also exists of adding a further category of data – for phases which have been obtained as the products of experimental work but which have not so far been found occurring naturally.

Another addition to MinIdent is a substantial list of discredited mineral names and synonyms. Entries are also included for minerals which although of dubious authenticity have not been unequivocally discredited and therefore remain in the database. At present there are about 1500 entries in the list, each of which includes a brief explanatory comment, the synonym (where applicable) and source reference(s). The scheme for naming rare earth-bearing minerals which was recently approved by the lMA has been fully implemented and, as far as possible, data associated with each rare earth variant of that species, appropriately assigned. However, the paucity of complete and reliable information on the concentrations of individual rare earths, continues to pose a problem. The re cent IMA decision to return to the original spelling of many non-English names has been implemented, although present software constraints preclude the inclusion of diacritical marks in such names.

Classification of minerals has been possible since the inception of ~dent. This facility has now been expanded so that the following divisions can be recognised where appropriate: variety, sub-species, species, series, sub-group, group, super-group, family, class and type. The top level “type” (e.g., silicates, oxides, sulphides, etc.) has been chosen to avoid ambiguity or overlap with other levels of classification previously used in the literature. Much progress has been achieved particularly with respect to rock-forming and more common minerals. For example, the full IMA amphibole classification scheme has been implemented (Goble &: Smith, 1988), and that for pyroxenes is presently being undertaken. However, much remains to be done and progress is hindered by the absence of a gene rally accepted and definitive classification scheme for minerals.

Other changes include the up-dating of the JCPDS PDF number and the entry or re-entry of the d-values for the five most intense lines from original literature sources. The algorithm that was specially developed for MinIdent to identify minerals on a very limited number of d-values has proved to work very well on pure phases. It is not intended for use with mixtures of phases.

Finally, a sub-set facility has been implemented which allows any group of minerals of interest to be selected from the database, and subsequently only these to be considered in the MATCH/IDENTIFY procedures. Such subsets are entirely flexible and could include categories such as “silicates”. “meteorite minerals” – or sets of minerals for instructional purposes. The use of subsets greatly reduces computational time for identification. It could prove extremely useful for the automation of mineral identification in combination with the analytical and image analysis capabilities of modern microbeam instruments.

Nortel

Nortel was a multinational telecommunications and data networking equipment manufacturer headquartered in Canada. At its height, Nortel accounted for more than a third of the total valuation of all the companies listed on the Toronto Stock Exchange (TSX), employing 94,500 worldwide. In the 1990s, Nortel absorbed Bell-Northern Research (BNR) into its R&D organization. Founded in 1895, the company ceased operations in 2009.

Between 1988 – 2002, David Pierre Leibovitz worked at BNR/Nortel.

Smith & Leibovitz (1987) MinIdent Reference Manual- A Data Base for Minerals and a FORTRAN 77 Program for Their IdentificationAbstract: Minldent is an interactive mineral identification and mineral data base management program written in FORTRAN 77. The data base contains compositional, optical and other parameters describing more than 3700 minerals. The data base management aspect of the program will not be used by the general user. It contains facilities to modify the data base through additions, deletions, etc. The normal usage consists of the following steps:

  1. entering data for a mineral to be identified (the unknown) or entering search criteria.
  2. identifying the mineral, or matching minerals meeting the search criteria.
  3. displaying data for specified, identified or matched minerals.

MinIdent-PCThis manual assumes the reader is already familiar to some extent with Minldent. It contains all the terms that may be explained via the ? / HELP / EXPLAIN commands.
