title: Open Data Transcripts from the Study: Exploring Educators Experiences Implementing Open Educational Practices

description: This dataset contains eight transcripts from interviews conducted with educators as part of a PhD study exploring open educational practices. The research focuses on how educators are using openly accessible sources of knowledge and open-source tools in ways that impact their pedagogical designs. Using a phenomenological approach with self-identifying open education practitioners, I explore how open educational practices are being actualized in formal higher education and impacting learning design. Specifically, I examine how educators are bringing elements of openness into their everyday teaching and learning practice using educational technologies. I draw upon Giddens (1986) structuration theory, further developed for use in technology adoption research most notably by DeSanctis and Poole (1994) and Orlikowski (2000). This approach positions technologies as being continually socially constructed, interpreted, and put into practice. In an organizational context, the use of technology is intrinsically linked with institutional properties, rules and norms, as well as individual perceptions and knowledge. The findings suggest that open educational practices represents an emerging form of learning design, which draws from existing models of constructivist and networked pedagogy. Open technologies are being used to support and enable active learning experiences, presenting and sharing learners work in real-time, allowing for formative feedback, peer review, and ultimately, promoting community-engaged coursework. By designing learning in this way, faculty offer learners an opportunity to consider and practice developing themselves as public citizens and develop the knowledge and literacies for working with copyright and controlling access to their online contributions, while presenting options for extending some of those rights to others. Inviting learners to share their work widely, demonstrates to them that their work has inherent value beyond the course and can be an opportunity to engage with their community.

title: Replication Data for: An Analysis of How the Twitter Discourse Surrounding Open Education Unfolded From 2009 to 2016

description: Inspired by open educational resources, open pedagogy, and open source software, the openness movement in education has different meanings for different people. In this study, we use Twitter data to examine the discourses surrounding openness as well as the people who participate in discourse around openness. By targeting hashtags related to open education, we gathered the most extensive dataset of historical open education tweets to date (n = 178,304 tweets and 23,061 users) and conducted a mixed methods analysis of openness from 2009 to 2016. Findings show that the diversity of participants has varied somewhat over time and that the discourse has predominantly revolved around open resources, although there are signs that an increase in interest around pedagogy, teaching, and learning is emerging.

title: Data From: Percent ash-free dry weight as a robust method to estimate energy density across taxa

description: Determining how energy flows through ecosystems reveals underlying ecological patterns that drive processes such as growth and food web dynamics. Models that assess the transfer of energy from producers to consumers require information on the energy content or energy density (ED) of prey species. ED is most accurately measured through bomb calorimetry, but this method suffers from limitations of cost, time and sample requirements that often make it unrealistic for many studies. Percent dry-weight (DW) is typically used as a proxy for ED, but this measure includes an indigestible portion (e.g. bones, shell, salt) that can vary widely among organisms. Further, several distinct models exist for various taxonomic groups, yet none can accurately estimate invertebrate, vertebrate and plant ED with a single equation. Here, we present a novel method to estimate the ED of organisms using percent ash-free dry weight (AFDW). Using data obtained from 11 studies diverse in geographic, temporal and taxonomic scope, AFDW, DW as well as percent-protein and percent-lipid were compared as predictors of ED. Linear models were produced on a logarithmic scale, including dummy variables for broad taxonomic groups. AFDW was the superior predictor of ED compared to DW, percent-protein and percent-lipid content. Model selection revealed that using correction factors (dummy variables) for aquatic animals (AA) and terrestrial invertebrates (TI) produced the best supported model – log10(ED) = 1.07*log10(AFDW) – 0.80 (R2 = 0.978, p&lt;0.00001) – with an intercept adjustment of 0.09 and 0.04 for AA and TI, respectively. All models including AFDW as a predictor had high predictive power (R2&gt;0.97), suggesting that AFDW can be used with high degrees of certainty to predict the ED of taxonomically diverse organisms. Our AFDW model will allow ED to be measured with minimal cost and time requirements and excludes ash-weight from estimates of digestible mass. Its ease of use will allow for ED to be more readily and accurately determined for diverse taxa across different ecosystems. This data file includes the original values and sources used to create the AFDW model.

title: Replication Data for: A prototype stochastic parameterization of regime behaviour in the stably stratified atmospheric boundary layer

description: A common classification scheme of the stably stratified atmospheric boundary layer (SBL) distinguishes between two distinct regimes, denoted the weakly and very stable boundary layers. Observations show that transitions between these two SBL regimes occur frequently within a night which is poorly represented in weather and climate models. In "A prototype stochastic parameterization of regime behaviour in the stably stratified atmospheric boundary layer" we developed a stochastic parameterization allowing to account for SBL regime transitions. The data at hand contains the single-column model output of wind, temperature, and turbulent flux profiles of both the reference experiment without the stochastic parameterization and the realization with the stochastic parameterization.

title: Replication Data for "A simple model of the climate states of Earth-like terrestrial planets"

description: Steady-state climates of terrestrial planets must be in radiative energy balance: absorbed sunlight and thermal emission equal on a global average. The simplest models that investigate radiative energy balance are zero-dimensional energy balance models (0-D EBM), in which planetary surface mean temperatures can be calculated simply from parametrized radiative fluxes. In "A simple model of the climate states of Earth-like terrestrial planets" we base these radiative flux parameterizations on 1-D radiative transfer calculations for Earth-like atmospheres, with an empirically-based parametrization of atmospheric humidity which permits a non-linear moistening process. The data at hand contain the surface temperature dependent outgoing longwave radiation calculations, and the determined atmospheric transmittance and reflectivity for the shortwave radiation wave bands.

title: Replication data for "Urbanization can increase the invasive potential of alien species"

description: This dataset was used to investigate whether the success of urban invaders is related to changes in species traits that enhance invasive potential. It was also used to explore whether a trophic mechanism helps explain the success of invaders in urban systems. All data come from one single model species, the guppy, Poecilia reticulata, which occurs in both urban and non-urban aquatic systems worldwide. This study took place in Rio de Janeiro, Brazil, where guppies have invaded many brackish and freshwater systems. We selected 6 urban stream reaches and 6 non-urban stream reaches, with the selection of urban streams based on the presence of development and evident direct sewage input, while non-urban streams were located inside parks and forest reserves. Within each treatment (urban, non-urban), 3 reaches had guppies as the only fish (guppy only), while in the other 3 guppies co-occurred with potential competitors and predators (guppy and other fish species). Whenever possible we sampled each reach in two years (2016-2017).

title: EUROSEM CSR Dataset

description: The EUROSEM CSR Dataset was created as a part of the Jean Monnet Network EUROSEM: ‘The Politics of the European Semester’ at the University of Victoria’s Department of Political Science (2018-2022). It provides researchers with data on all country-specific recommendations (CSR) put forward by the European Commission in the European Semester. For the dataset, all CSRs to member states of the euro area from 2012 to 2019 have been considered. The data has been manually coded by a group of researchers familiar with language used in official EU publications. Each country has been assigned to two coders who reviewed and coded the CSRs independently. Their codings have been controlled for intercoder reliability. In total, 1875 CSRs are included in the dataset: 517 ‘headline CSRs’ that include the general policy guidance by the European Commission in a broad policy area for the country in question, as well as 1268 ‘sub-CSRs’ which focus on targeted elements of the broader guidance. The EUROSEM CSR Dataset was created with support of the ERASMUS+ Programme of the European Union. The European Commission's support for the production of this publication does not constitute an endorsement of the contents, which reflect the views only of the authors, and the Commission cannot be held responsible for any use which may be made of the information contained therein.

title: CTD profile in IODP CORK U1364A borehole at ONC NEPTUNE observatory site Clayoquot Slope, Cascadia Accretionary Prism

description: Ocean Networks Canada (ONC) operates and maintains innovative cabled observatories that supply continuous power and Internet connectivity to various scientific instruments located in coastal, deep-ocean, and Arctic environments. The Clayoquot Slope IODP (Integrated Ocean Discovery Program) borehole observatory CORK U1364A is located in the Vancouver Margin of the northern Cascadia Subduction Zone, ~20km landward of the accretionary prism toe. Here, sediments scraped from the subducting Juan de Fuca plate are deposited and the accreted sedimentary section is ~5 km thick with gas hydrate formation in the upper hundred meters of sediment. The CORK (Circulation Obviation Retrofit Kit) observatory was installed in 2010 during IODP Expedition 328 (Davis Malone, 2010; Davis Heesemann, 2011). This location was chosen to observe the fluid flow, mechanical and formation properties of the accretionary prism, allowing for long-term monitoring of deformation, seismic activity, and gas hydrate accumulation. In May 2014 a temperature profile was measured by lowering a CTD (Conductivity-Temperature-Depth) down IODP borehole observatory CORK U1364A. The CTD profile was obtained during Ocean Networks Canada NEPTUNE Maintenance Cruise 2014-05 using the remotely operated vehicle (ROV) CSSF-ROPOS from the CCGS John P. Tully. Dive log entries are available from Dive R1694 and a video recording of the experiment is accessible through SeaTube, ONC’s video player (https://data.oceannetworks.ca/SeaTube?resourceTypeId=1000resourceId=1001diveId=410time=2014-05-24T15:43:08.000Z). CTD data was collected using the factory calibration settings and downloaded from the instrument using the CTD manufacturers software. The initial purpose of this experiment was to determine the open depth of the borehole. The data of the hydrological observatory have been used in multiple subsequent studies to investigate pressure and temperature changes of the subseafloor (Becker et al. 2020, Mcguire et al. 2018). Boreholes drilled within the accretionary prism help to better understand the relationship between dynamic processes such as tectonic motion and deformation, internal plate strain, and earthquakes, as well as gas hydrate formation and accumulation.

title: Six years (2009-2015) of oceanographic temperature, salinity, pressure, density and dissolved oxygen observations from a Vancouver Island shelf cabled observatory.

description: Ocean Networks Canada operates and maintains innovative cabled observatories that supply continuous power and Internet connectivity to various scientific instruments located in coastal, deep-ocean, and Arctic environments. Instruments at Folger Deep are mounted on an steel and plastic instrument platform (IP) placed on the seafloor. The IP also houses a junction box which is part of the system that facilitates power and communications. The near-coast location of the platform off the West Coast of Vancouver Island is well suited for the monitoring of the variability of the coastal water properties (e.g. temperature, salinity, oxygen) and hence the timing of upwelling and downwelling circulation associated with the northern end of the California Current system which is the prime driver of the local oceanic environment. The instrument deployments in the 6 year dataset were conducted over six expeditions, spanning 28th August 2009 to 5th May 2017. Based on a two year calibration schedule, the CTD and oxygen sensors were either recovered and returned to the manufacturer for servicing and replaced by a new instrument, or serviced on the ship and then redeployed. Due to ship-based deployments, minor differences in location and depth have occurred between deployments. Underwater maintenance was performed by various remotely operated vehicles and video recordings of the work are accessible through SeaTube, ONC’s video player.

title: Data from: A climate-associated multi-species cryptic genetic cline in the northwest Atlantic"

description: This is supplementary environmental data used in environmental population structure analyses: "A climate-associated multi-species cryptic genetic cline in the northwest Atlantic" This data is described in the methods as: Temperature and salinity data were aggregated to seasonal climatological data (averaged across 2002-2012) layers, effectively corresponding with winter (January – March), spring (April – June), summer (July – September), and fall (October – December). Seasonal sea surface temperature (SST) and sea surface salinity (SSS) were assembled at spatial resolutions interpretable to 1 km2 from Level 3 SST climatological satellite data, including Advanced Very High Resolution Radiometer data (AVHRR Atlantic; compiled by Fisheries and Oceans Canada) and global oceanographic climatological SSS composites (Tyberghein et al. 2012). Benthic temperature and benthic salinity climatological data layers were assembled at spatial resolutions interpretable to 8 km2 from a numerical climatological model (GLORYS2V1) adapted to the study area by Fisheries and Oceans Canada. We represented topographic complexity of the seafloor (interpretable to 1 km2) by east-west and north-south components of aspect, slope, plan and profile curvature, and rugosity (Sbrocco & Barber 2013). These data layers were used as predictive surfaces for each of the five species native to the range (Table 1). From these data layers, we extracted point estimates of each environmental variable for each genetic sample location to evaluate genetic-environmental relationships. This dataset represents these point estimates.

title: Data from: Genome-wide evidence of environmentally mediated secondary contact of European green crab (Carcinus maenas) lineages in eastern North America

description: Genetic-environment associations are increasingly revealed through population genomic data and can occur through a number of processes, including secondary contact, divergent natural selection, or isolation-by-distance. Here we investigate the influence of the environment, including seasonal temperature and salinity, on the population structure of the invasive European green crab (Carcinus maenas) in eastern North America. Green crab populations in eastern North America are associated with two independent invasions, previously shown to consist of distinct northern and southern ecotypes, with a contact zone in southern Nova Scotia, Canada. Using a RAD-seq panel of 9137 genome-wide SNPs, we detected 41 SNPs (0.49%) whose allele frequencies were highly correlated with environmental data. A principal components analysis of 25 environmental variables differentiated populations into northern, southern, and admixed sites in concordance with the observed genomic spatial structure. Furthermore, a spatial principal components analysis conducted on genomic and geographic data revealed a high degree of global structure (p&lt;0.0001) partitioning a northern and southern ecotype. Redundancy and partial redundancy analyses revealed that among the environmental variables tested, winter sea surface temperature had the strongest association with spatial structuring, suggesting that it is an important factor defining range and expansion limits of each ecotype. Understanding environmental thresholds associated with intraspecific diversity will facilitate the ability to manage current and predict future distributions of this aquatic invasive species.
