title: Supplementary Material for: Utricular Dysfunction and Hearing Impairment Affect Spatial Navigation in Community-dwelling Healthy Adults: Analysis from the Baltimore Longitudinal Study of Aging

description: Introduction: Spatial navigation, the ability to move through one’s environment, is a complex skill utilized in everyday life. The effects of specific vestibular end-organ deficits and hearing impairments on spatial navigation have received little to no attention. We hypothesized that hearing impairment adversely affects spatial navigation and that bi-modal impairments (vestibular and hearing) further impair navigation ability. 

Methods: Data from 182 participants in the Baltimore Longitudinal Study of Aging who had interpretable results for the video head impulse test (vHIT), cervical (cVEMP) and ocular (oVEMP) vestibular evoked myogenic potentials, audiometric testing, and the triangle completion test (TCT) were retrospectively analyzed. Multiple linear regression, controlling for age, sex, and cognition, was employed to identify predictors of TCT performance in terms of end-point error, angle deviation, and distance walked.

Results: oVEMP abnormalities were associated with larger end-point error (p=0.008) and larger angle deviation (p=0.002) but were not associated with distance walked (p=0.392). Abnormalities on cVEMP and vHIT were not associated with distance walked (p=0.835, p=0.300), end-point error (p=0.256, p=0.808), or angle deviation (p=0.192, p=0.966). Compared with normal hearing adults, hearing impaired adults walked a shorter distance during the TCT (p=0.049) but had similar end-point error (p=0.302) and angle deviation (p=0.466). There was no interaction between vestibular and hearing function for predicting spatial navigation ability.

Conclusion: In this cohort analysis, utricular dysfunction and hearing impairment were associated with poorer spatial navigation performance. We postulate that hearing impairment negatively affects one’s ability to use real-time, intrinsic auditory cues and/or prior experience to guide navigation.

title: Implementation of a Twitter-supported Personal Learning Network to Individualize Teacher Professional Development

description: The results were mixed. Data analysis indicated that a Twitter-supported personal learning network was useful in meeting the individual professional learning needs of some, but not all participants. Secondary research questions addressed how Twitter can be used to develop a personal learning network, the types of resources and learning opportunities teachers would find using Twitter, teachers’ perceptions of the value of a personal learning network to support their professional learning goals, teachers' perceptions of the efficacy of Twitter to individualize professional development, and whether teachers’ progress toward a professional development goal via the use of a personal learning network could be enhanced. The results of the secondary questions indicated that Twitter was useful in developing a personal learning network; all of the participants reported finding value in a Twitter-supported personal learning network in supporting the individual professional learning needs of teachers.

title: Clustering of Global Magnetospheric Observations

description: The data here are for an article submission to Journal of Geophysical Research: Machine Learning and Computation. It includes:



A dataset of THEMIS and MMS magnetic field and ion observations used to train the model (mms_and_themis.csv)

 The bow shock (bs.csv) and magnetopause (mp.csv) crossings found from the resulting predictions

A labeled dataset containing MMS1 observations that is joined with the labels of Olshevsky et al (2021) (labeled_mms1_NovDec2017.csv). Our model's predictions are also included in this dataset.


These datasets can be easily loaded using the Python Data Analysis Library, Pandas. The models we created for our article are included in a separate Zenodo repository.

title: AusENDVI: A long-term NDVI dataset for Australia

description: AusENDVI (Australian Emprical NDVI) is a monthly, 5-km gridded estimate of NDVI across Australia from 1982-2022. It is built by calibrating and harmonising NOAA's Climate Data Record AVHRR NDVI data to MODIS MCD43A4 NDVI using a gradient boosting ensemble decision tree method.  Additionally, the datasets are gapfilled using a synthetic NDVI dataset.  The methods are extensively described in an Earth System Science Data pre-publication.

AusENDVI consists of several datasets, each dataset has a description in the attributes of the NetCDF file that describes its provenance.  The naming convention is "AusENDVI_<model_type>_<year_range>_<version>.nc". 



AusENDVI-clim_1982_2013. Calibrated and harmonised NOAA's Climate Data Record AVHRR NDVI data from Jan. 1982 to Dec. 2013. This version of the dataset used climate data in the calibration and harmonisation process. The dataset has not been gap filled, and extra data has been filtered/removed beyond the typical QA filtering using methods described in the publication.

AusENDVI-noclim_1982_2013. Calibrated and harmonised NOAA's Climate Data Record AVHRR NDVI data from Jan. 1982 to Dec. 2013. This version of the dataset did not use climate data in the calibration and harmonisation process. The dataset has not been gap filled, and extra data has been filtered/removed beyond the typical QA filtering using methods described in the publication. 

AusENDVI-synthetic_1982_2022. This dataset consists of synthetic NDVI data that was built by training a model on the joined _AusENDVI-clim_ and _MODIS-MCD43A4 NDVI_ timeseries using climate, woody-cover-fraction, and atmospheric CO2 as predictors.

AusENDVI-clim_gapfilled_MCD43A4_1982_2022. This dataset consists of calibrated and harmonised NOAA's Climate Data Record AVHRR NDVI data from Jan. 1982 to Feb. 2000, joined with MODIS-MCD43A4 NDVI data from Mar. 2000 to Dec. 2022. This version of the dataset _used climate data_ in the calibration and harmonisation process. The dataset has been gap filled using _AusENDVI-synthetic_

 AusENDVI-noclim_MCD43A4_1982_2022. This dataset consists of calibrated and harmonised NOAA's Climate Data Record AVHRR NDVI data from Jan. 1982 to Feb. 2000, and MODIS-MCD43A4 NDVI data from Mar. 2000 to Dec. 2022. This version of the dataset _did not use climate data_ in the calibration and harmonisation process. The dataset has not been gap filled.


All datasets are in "EPSG:4326" projection, and have a spatial resolution of 0.05 degrees. Geographic coordinate information is contained in the "spatial_ref" variable.

A Jupyter Notebook is also provided that shows how to load, plot, QC mask, reproject, and gap-fill AusENDVI datasets. The notebook is effectively a 'readme' file.



The notebook is also available to view/download here


An open-source github repository details the methods used to create these datasets
