History with Data: from an undergraduate student, horticulture scientist perspective
The effect of low level electromagnetic fields on seed growth
Scientific Research Plan
Experiment: • 5 groups of 100 phaseolus vulgaris seeds• 20 seeds of each group potted in one gallon pots• 80 seeds of group petri dish
• Home control• Travel control• SC1= stone chamber 30 minutes• SC2= stone chamber 70 minutes• CC1= corbelled chamber 70 minutes
Data Collection
• Germination Rate• Shoot Height• Leaf Area Index• Dry Weight
Data Analysis
• Positively charged ions sink to the floor• Negatively charged ions rise• Separation of charges creates electromagnetic pulsing within the airspace• Pulsing is measure by Electrostatic voltmeter

History with Data: from a working horticulture scientist perspective
Trial Garden Research
• Data collection and recording• Data input: Access versus Excel • Plant Ratings• Type of data:
* genus, species, cultivar, source, common name, unique ID, botanical family* flower date* height (multiple data points)* spread* flower color* foliage color
Trial Garden Data
Data Collection: sophisticated!
Data Input: Access
Example of visible data
History with Data: from a graduate student, information scientist perspective
UNCA Special Collections: HACA maps and collection
• Provenance• Metadata creation and planning• Format modification• Unique ID planning/creation• Data input practice/mishaps• Transferal of Access metadata to Frontpage
History with Data: current concepts
• Provenance• Metadata standards and use• Controlled Vocabulary• Organization of Data• Levels of Description• Information Retrieval• Data Indexing
Future with Data: concepts into practice
Understanding of data lifecycle components, lacking some applications
• Look forward to: – format modification– file conversions– data migration– further data description– data ingestion– data appraisal– data sharing, access, and reuse techniques– data encoding
