Preparing educational presentation about therapeutic exercises to resident physiatrists
<p>This study evaluated the effectiveness of ChatGPT-4o, a generative artificial intelligence (AI) platform, in preparing educational presentation on therapeutic exercises specifically designed for physiatry residents. Both a physiatry expert and ChatGPT-4 created PowerPoint slides for a presentation on therapeutic exercises using the same reputable sources. Two other physiatry experts, blinded to the origin of the presentation and each other's scores, independently assessed both presentations using four of the CLEAR criteria (completeness, lack of false information, appropriateness, and relevance).</p> <p>Statistical analyses confirmed the interrater reliability. The average scores of the expert-prepared slides were significantly higher than those of the AI-prepared slides. However, when assessing the presentations as a whole, no statistically significant difference emerged between the average AI and expert scores. The overall scores of the AI-prepared slides were rated between good and excellent, while the expert-prepared slides were rated as excellent. Similarly, when assessing the presentations as a whole, the AI performed good whereas expert performed excellent. Upon evaluating the variability within the model for the assessed criteria, it was found that the AI ranked highest in relevance, whereas the expert ranked highest in terms of lack of false information.</p> <p>These findings indicated that although ChatGPT-4o can produce effective educational content, the expert still outperformed AI. This underscores the importance of professional oversight in maintaining the educational quality of resident physician training. Furthermore, fostering collaboration between humans and AI can lead to enhanced educational outcomes in the field.</p>

Data presented in figure 2 of "Evidence of nitrate based nighttime atmospheric nucleation driven by marine microorganisms in the South Pacific"
<p>Data collected at the Maïdo observatory between April 24th and April 29th 2018 used in the calculation of statistics presented in Figure 2 of "Evidence of nitrate based nighttime atmospheric nucleation driven by marine microorganisms in the South Pacific". Data were obtained by an API-ToF-MS; molecular clusters are grouped by family as described in Chamba et al. 2023. Data were first filtered based on SO2 mixing ratios to exclude the periods when the station was under the influence of the volcanic plume of the Piton de la Fournaise. Hourly averages of the signals of interest were then calculated and only the data corresponding to the periods during which the station was in the free troposphere were considered.</p>
Mohonk Preserve Phenology Monitoring 1912-present
Phenology records around Mohonk Lake date back to the early 1900s, when Daniel and Keith Smiley started noting the date of spring bird arrivals. The Preserve’s Daniel Smiley Research Center continues this tradition of natural history observation and has expanded the scope of the Smileys’ phenology records to monitor seasonal changes in plants and other fauna at Mohonk Preserve on local, regional, and national levels. Alongside our long-term weather data, these data provide insight into the changing communities in the Mohonk Preserve in response to changing climate. These data include first occurrence dates for each of the taxa and associated life stages in the vicinity of Mohonk Preserve and were collected by staff at the Daniel Smiley Research Center.
Lake Superior cyanobacterial bloom reports, 2012 - present
Lake Superior is a cold, oligotrophic lake. It is the largest freshwater lake in the world by surface area and the largest of the Laurentian Great Lakes with binational (United States and Canada) and multi-state (Michigan, Wisconsin, Minnesota) borders. Lake Superior is a globally important freshwater resource. Beginning in 2012, researchers and resource managers began receiving reports of cyanobacterial blooms in the western arm of the Lake. Cyanobacterial blooms have been reported nearly every year since. The purpose of this dataset is to collect observations of cyanobacterial blooms for Lake Superior and connecting waters, document patterns in their occurrence, and provide insights into their causes. For this dataset, a cyanobacterial bloom is defined as an aggregation of cyanobacterial biomass in some or all of the water column, which may lead to the occurrence of surface scums or subsurface maximums. This dataset relies on observations, data, photographs, and insights from a wide range of agency staff and individual members of the public with key input from participants in the Lake Superior Algal Bloom and Nutrient Subgroup collaboration. This dataset only includes reported blooms, and likely doesn’t include all actual bloom events. Additionally, there may be more than one report for a single bloom event, depending on its size. For example, in 2018 there was a widespread bloom event which resulted in numerous reports. Interpretation of this dataset should incorporate these nuances. Observations in the dataset were assigned one of four verification statuses to communicate the level of certainty in the cyanobacterial bloom event. Additional information on taxonomy and/or toxin analyses can be made available upon request.
History of Acid Precipitation on the Shawangunk Ridge: Mohonk Preserve Precipitation Depths and pH, 1976 to Present
We, the staff, volunteers and associates of the Mohonk Preserve, have been collecting precipitation data at Mohonk Lake since January 1976. The Level1_MohonkPrecipData includes precipitation depths recorded either during or at the conclusion of every precipitation event. This dataset additionally includes pH measurements for most precipitation collections.The Level2_MohonkPrecipData summarizes data collections into precipitation events where the precipitation depth is cumulative and the pH is averaged for all data collections in that event. We measured precipitation via a National Weather Service Rain Gauge and the pH was measured at a Cooperative Weather Service Station at Mohonk Lake.
Mohonk Preserve Amphibian and Water Quality Monitoring Dataset at 11 Vernal Pools from 1931-Present
"The Mohonk Preserve's Daniel Smiley Research Center has been monitoring species occupancy, reproductive success, and water quality of 11 vernal pools (Ski Loop, Bonticou, Terrace, Long Woodland Pool, Long Woodland Swamp, Oakwood, Sleepy Hollow, Hermits, North Mud Pond, Canaan, and Talus) on the Preserve each spring from April 1931 to May 2019 (present). This project aims to document changes in the reproductive behavior and phenology of amphibians and allow research access to historical, longitudinal records. The dataset is a paired record of amphibian occurence with environmental indicators spanning nearly 90 years of data collection. The dataset includes environmental conditions for the 730 sampling events associated with the species occurences with complete coverage air temperature and precipitation records and partial coverage for a variety of other weather and water quality measures. Species occurence data collection has included species identification and counts of live and dead adults, mated pairs, spermatophores, egg masses, juveniles, and tadpoles counts as well as a record of the level of frog calling. Weather conditions including precipitation, sky and wind codes; and water quality measurements including water temperature, pH, and depth. Collection of data was sporadic from 1931 - 1991 but has been collected consistently from 1991 to present. We also began monitoring dissolved oxygen, nitrate concentrations, and conductivity of the vernal pools using a YSI Sonde Professional Plus Instrument and turbidity using a turbidity tube in February 2018. The data collection is ongoing, as are digitization efforts, and the data package will receive periodic updates."
Rabbit Population Dynamics in Chihuahuan Desert Grasslands and Shrublands at the Sevilleta National Wildlife Refuge, New Mexico (1992-present) (Reformatted to a Darwin Core Archive)
This data package is formatted as a Darwin Core Archive (DwC-A, event core). For more information on Darwin Core see https://www.tdwg.org/standards/dwc/. This Level 2 data package was derived from the Level 1 data package found here: https://pasta.lternet.edu/package/metadata/eml/edi/334/2, which was derived from the Level 0 data package found here: https://pasta.lternet.edu/package/metadata/eml/knb-lter-sev/23/121705. The abstract below was extracted from the Level 0 data package and is included for context: This study explores the population dynamics of black-tail jackrabbits (Lepus californicus) and desert cottontail rabbits (Sylvilagus auduboni) in the grasslands and creosote shrublands of McKenzie Flats, Sevilleta National Wildlife Refuge. The study was initiated in January 1992, and continues quarterly each year. Rabbits are sampled via night-time spotlight transect sampling along the roads of McKenzie Flats once during winter, spring, summer, and fall. The route is 21.5 miles long. Measurements of perpendicular distance of each rabbit from the center of the road are used to estimate densities (number of rabbits per square kilometer) via Program DISTANCE. Results from January 1992 to May 2004 indicated that spring was the period of peak density period, with generally steady declines through the rest of the year until the following spring. Evidence of a long-term "cycle" (e.g., the 11-year-cycle reported for rabbits in the Great Basin Desert) does not appear in the Sevilleta rabbit populations.

Air Temperature, Soil Temperature, Precipitation, Snow Depth at Long Term Tree Growth Sites; 1968-Present : Weekly
Part of the Long Term Tree Growth study. This dataset is an accumulation of various manual measurements made on a weekly to monthly basis. It originally included snow stakes, rain buckets, max/min thermometers and a series of soil temperature sensors. Over the years equipment has changed. The soil temperature sensors exceeded their field life during the 1990's and were dropped from the study. In 2001 logging air temperature and relative humidity sensors were installed and those measurements were discontinued. In 2002 logging rain gauges were installed to replace the manual buckets. Both styles were during that growing season and the manual buckets were removed before the 2003 field season. All that remains active in this dataset are the snow stake measurements.
Long Term Tree Growth Sites: Hourly Temperature and Hourly Relative Humidity at 150 cm from 1988 to Present
