Aboriginal Housing Management Association (AHMA)

This dataset contains five files representing two custom-ordered tables from Statistics Canada covering the 2006 Census of Canada. Three of the files contain data for the province of BC, census division, and census subdivision for the specifications in "Table 5" below, while the other two files have the same geographies but with data corresponding to "Table 6" below.

This is part of a larger order of a total 17 files from 6 tables covering the 2021, 2016, and 2006 censuses. The tables were ordered to support and populate the Indigenous-led Housing Needs Assessment Tool (IHNAT).

The tables contain data on Indigenous identity of the Primary Household Maintainer (PHM) cross-tabulated with core housing need indicators, tenure, household characteristics and dwelling characteristics, for private households in British Columbia. Each census year is represented by two complementary tables: one table combining housing indicators with tenure, household and dwelling characteristics, and a second table combining housing indicators with income-to-AMHI ranges, mobility status, age of the PHM and additional household characteristics. Due to file size limitations, several tables are split across multiple geography-based parts (e.g., BC and CSDs vs. census divisions), and for the 2021 Census, the second table is further split into geographies below and at/above 100,000 population, since a household-level gender diversity indicator is only released for larger populations.

The dataset is in Beyond 20/20 (.ivt) format.

Long-term monitoring of macroalgal biodiversity in Stanley Park, Vancouver, British Columbia

2026-10-06

The sampling was started by Varoon P. Supratya and Siobhan Schenk.

Starting in September 2025, Evan Kohn, who has been very involved with the transects since 2023, is now co-leading the project.

Macroalgae are marine foundation species in intertidal ecosystems, but data regarding their historical abundance, diversity, and phenology remains lacking in many regions, including British Columbia.

This absence of historical baselines may hinder assessments of how macroalgae are affected by anthropogenic stressors, such as extreme weather events (e.g., 2021 heat dome) or invasive species. Obtaining baseline data may be especially important for urban intertidal zones, where the impact of increasing anthropogenic stressors is underappreciated.

To fill this data gap, they started a collaborative long-term survey in 2021 to document year-round macroalgal biodiversity in a highly biodiverse urban intertidal zone around the Girl in a Wetsuit Statue in Stanley Park, Vancouver, British Columbia, Canada (49.30275394688415, -123.12643462372476).

Impact of hand position on force-time characteristics during spinal manipulation and mobilization: an observational study

2026-10-06

This dataset presents information related to a repeated-measures observational study examining the effect of hand position on the force-time characteristics of thoracic posterior-to-anterior spinal manipulation and spinal mobilization. The goal of the study was to compare three hand positions commonly taught in chiropractic education (thenar bilateral, crossed bilateral hypothenar and reinforced unilateral hypothenar) and to assess the between-session reliability of force-time characteristics among chiropractic interns. Ten interns in the final year of the chiropractic program completed two identical sessions approximately one week apart between May and August 2022. During each session, participants performed 10 spinal manipulations and 10 spinal mobilizations for each hand position on a human-analog manikin positioned on a treatment table equipped with a force platform (2,000 Hz), for a total of 1,200 trials. The final dataset includes: (1) the force-time characteristics of each spinal manipulation trial (peak force, force amplitude, thrust duration, rate of force application, peak preload force, release force); (2) the force-time characteristics of each spinal mobilization trial (peak force, duration, frequency). The data are quantitative in nature and provide a foundation for improving the teaching of manual therapy techniques, the consistency of force delivery and patient safety in chiropractic education. // Ce jeu de données présente les informations liées à une étude observationnelle à mesures répétées portant sur l'effet de la position des mains sur les caractéristiques force-temps de la manipulation et de la mobilisation vertébrales thoraciques postéro-antérieures.L'objectif de l'étude était de comparer trois positions de mains couramment enseignées en formation chiropratique (thénar bilatérale transverse, hypothénar bilatérale croisée et hypothénar unilatérale renforcée) et d'évaluer la fidélité inter-sessions des caractéristiques force-temps chez des internes en chiropratique. Dix internes en dernière année du programme de chiropratique ont complété deux sessions identiques à environ une semaine d'intervalle, entre mai et août 2022. Lors de chaque session, les participantes et participants ont réalisé 10 manipulations et 10 mobilisations vertébrales pour chaque position de mains sur un mannequin anthropomorphique placé sur une table de traitement munie d'une plateforme de force (2 000 Hz), pour un total de 1 200 essais. Le jeu de données final comprend : (1) les caractéristiques force-temps de chaque essai de manipulation vertébrale (force maximale, amplitude de force, durée de l’impulsion, taux d'application de la force, force de mise en tension, force de relâchement) ; (2) les caractéristiques force-temps de chaque essai de mobilisation vertébrale (force maximale, durée, fréquence). Les données recueillies sont de nature quantitative et constituent une base pour améliorer l'enseignement des techniques de thérapie manuelle, la constance de l'application de la force et la sécurité des patients en formation chiropratique.Ethical considerations prevent this dataset from being publicly available.

Supplementary Data and Models for Li, Na, and K Cations and Bisulfide Anion in Aqueous Solutions

2026-10-06

Quantum chemical data utilized in characterizing aqueous species for rationalizing [Fe-S]-maquette formation during the reductive dissolution of pyrite mineral.

The interaction of the counterions (M⁺_(aq), where M = Li, Na, K) and high levels of HS^–_(aq) were investigated using a set of density functionals that included representative set of advanced hybrid functionals with generalized-gradient approximations, varying amount of Hartree-Fock exchange and dispersion corrections: wB97xD, cam-B3LYP+D3BJ, MN15, OmPW1PBE, PBE, and PBE0. In all calculations, we employed the Ahlrich all-electron basis set def2-TZVP supplemented with polarization functions on both the H-s and the heavy atoms, as well as a single set of diffuse functions in order to describe the ground and excited states of anionic species. For the accurate representation of the aqueous solvation, we converged a model series for each cation/anion pairs models with gradually increased number of explicit water solvent molecules. All structures were embedded into a polarizable continuum model (SMD) with published water parameters for long-range electrostatic and local non-electrostatic implicit solvation interactions.

The equilibrium ground state structures of HS^–/M⁺ hexaaquo ions, (H_{2M⁺SH^–(H₂O)₄ ion pairs, and (H₂O)₅M⁺SH^–(H₂O) ion adducts were included.}

The electronic absorption spectra were calculated using the time-dependent formalism building on the first 10, electric-dipole allowed excited states that gives experimentally detectable absorption bands. The simulated UV/visible spectra were generated by employing 15 nm bandwidth at half peak height.

All computational results were visualized and plotted using ChemCraft 1.8.

The presented density functional theory calculations show that the 230 nm band originates from HS–(aq) and cation interactions regardless whether we chose the highly hypothetical gas phase model that provides the best case scenario for donor/acceptor interactions due to maximal covalent cation/SH anion interaction or the realistic solvated model for ion pairs or ion adducts that cause non-ideality of aqueous solutions already in the mM range or water molecules are inserted in between the cation and the anion as in the ion adducts, respectively. The presence of counterions that are non-covalently bound in the ion adducts acts as a positive potential around the HS^–_(aq). This pulls away, distorts, and polarizes the electron density, and consequently weakens the S–H bond as it’s pK_a value lowers. Along this weakening, the S 3p^z – H 1s covalent interaction lessens and thus the splitting between the sigma/sigma* orbitals will decrease; hence S lone pair to S–H sigma* transitions move to lower energy as they red shift. The solvated HS^–_(aq) has absorption features, but not at 230 nm. Therefore, we can conclude that perturbations to the bisulfide electronic structure in the presence of counterion interactions will be responsible for lowering the absorption energy toward longer wavelengths as observed experimentally.

Supporting curators as core infrastructure for data sharing: A national survey of Canadian repository administrators

2026-10-03

This study examined how Canadian institutions support the administration and curation of research data within repository services, with the goal of understanding the human and organizational conditions needed to advance open science. As data sharing requirements from funders and publishers expand, understanding how institutions support data deposit, curation, and long‑term stewardship is essential for sustaining open science. The study aimed to assess institutional readiness, characterize service models, identify challenges faced by research data repository administrators, and evaluate the perceived value of a national community supporting this shared infrastructure. A national survey was sent to all Canadian institutions operating Dataverse collections as part of the emerging national shared infrastructure or separate institution-managed installations. Forty‑six institutions responded to the survey, representing a majority of the population at the time of data collection. Institutions reported substantial variation in staffing and service maturity, with many small institutional participants facing acute capacity limitations. Most institutional participants allocated minimal staff time to repository administration, yet the majority expected deposit rates to increase in the near term. Larger participating institutions were more likely to report robust and well‑established services, while smaller participating institutions frequently described their services as emerging or still under development. Across institution sizes, administrators identified researcher awareness, limited incentives for data deposit, and insufficient staffing as major challenges. While many participating institutions conducted basic dataset review activities, advanced curation services were less common, particularly among smaller institutions. Respondents emphasized the value of participating in a national community of practice, which provides shared expertise, collective problem‑solving, and a foundation for strengthening open science capacity across diverse institutional contexts. These findings underscore that open science relies fundamentally on human expertise: sustaining high‑quality, equitable, and trustworthy data sharing requires dedicated investment in the people and processes that make open data possible.

Labour Force Survey, August 2026 [Canada]

2026-10-02

LFS data are used to produce the well-known unemployment rate as well as other standard labour market indicators such as the employment rate and the participation rate. The LFS also provides employment estimates by industry, occupation, public and private sector, hours worked and much more, all cross-classifiable by a variety of demographic characteristics. Estimates are produced for Canada, the provinces, the territories and a large number of sub-provincial regions. For employees, data on wage rates, union status, job permanency and establishment size are also produced. These data are used by different levels of government for evaluation and planning of employment programs in Canada. Regional unemployment rates are used by Employment and Social Development Canada to determine eligibility, level and duration of insurance benefits for persons living within a particular employment insurance region. The data are also used by labour market analysts, economists, consultants, planners, forecasters and academics in both the private and public sector. Statistical activity Together, four statistical programs tell a more complete story of current labour market events. These programs are: the Labour Force Survey (LFS), the Survey of Employment, Payrolls and Hours (SEPH), Employment Insurance Statistics (EIS), and the Job Vacancy and Wage Survey (JVWS). Every month, the LFS provides timely data on the labour market, including the unemployment rate and demographic analysis. Later on, the SEPH report shows greater detail on non-farm industry employment and earnings and the JVWS supplies preliminary indicators on job vacancies. EIS provides substantial detail on Employment Insurance benefits by geography, socio-demographics and former occupation. Every quarter, the JVWS provides detailed information on job vacancies by occupation and economic region.

Data and code from: Plant species responses to nutrient addition, but not to herbivore exclusion, strengthen over time in global grasslands

2026-10-02

Abstract

Nutrient enrichment and altered herbivory are among the most pervasive drivers of change in grasslands worldwide, yet how their effects on plant communities accumulate or fade over time, and which species drive those effects, remains poorly resolved. Using long-term data from the Nutrient Network (NutNet), a globally distributed experiment, we examined how grassland plant community composition responded to factorial nutrient addition (NPK) and herbivore exclusion (fencing) across 98 sites and up to 12 years of treatment. For each site and year, we quantified the overall compositional difference between treatments (PERMANOVA), identified the species contributing most to those differences (SIMPER), and classified species as indicators of each treatment (Indicator Species Analysis), linking these responses to each species' dominance, commonness, functional group, lifespan, and provenance. We found that compositional divergence under nutrient addition strengthened over time and was driven disproportionately by a relatively small subset of species, particularly dominant and common ones, whereas the effects of herbivore exclusion were comparatively weak and transient. These results highlight the importance of species-level dynamics for understanding how grassland biodiversity responds to global change. This package provides the processed data and annotated R code needed to reproduce all analyses and figures in the associated study.

Supplemental data for: A labor of love? Gender, animal welfare, and the costs of caring in livestock veterinary practice

2026-10-02

This dataset contains the supplementary materials of the study: "A labor of love? Gender, animal welfare, and the costs of caring in livestock veterinary practice." Abstract: Human-animal interactions can exert both positive and negative influences on the welfare of animals. These interactions are shaped by human attitudes and behaviors that are, in turn, influenced by a multitude of factors, including gender. Despite this, there remains a dearth of research examining the role of gender in the way animal care is performed and its influence on persistent animal welfare dilemmas. This is particularly relevant in livestock production, where economics and industry culture exert considerable influence on animal care practices. We therefore sought to explore the influence of gender on human-animal relationships; specifically, the relationship between livestock veterinarians and the animals they care for. We conducted interviews with non-male identifying veterinarians (n = 21) who worked or had worked in food animal practice at some point in their career. Interviews were recorded, transcribed, and underwent reflexive thematic analysis. Analysis resulted in three major themes: 1) Earning one’s place in a profession once built for others; 2) Care in conflict: relational versus instrumental care; and 3) Enduring structures and shifting norms. Our results describe a gendered paradox of care in livestock veterinary medicine whereby animal care requires empathy and emotionality. However, industry culture often devalues these qualities as implicitly feminine, instead rewarding stoicism and emotional containment. Despite this, our participants described their ongoing work in challenging hegemonic gender norms and actively rebuilding the emergent profession from within. We contend that addressing the paradox of care in livestock veterinary practice requires supporting all veterinarians in embracing both emotionality and rationality, with care ethics offering a promising avenue for centering the value of relational care.

Canadian Health Survey on Seniors, 2019-2020

2026-10-01

The Canadian Health Survey on Seniors (CHSS) is a cross-sectional survey that collected information related to health status, health care services, supports, as well as social and health determinants for the Canadian population aged 65 and over. The survey is a supplement to the Canadian Community Health Survey (CCHS). The CHSS includes 15 minutes of content asked at the end of the CCHS to respondents aged 65 and over. The surveys are designed to flow seamlessly from the CCHS into the CHSS.

The objectives of the Canadian Health Survey on Seniors are:

To better understand what contributes to healthy aging by collecting data on the health and well-being of seniors, including their use of health care services and supports, as well as social, demographic, geographic and economic determinants.

Due to the COVID-19 pandemic, collection was paused from mid-March until September, 2020. When collection resumed in September, a new module was added to the CCHS with content related to the pandemic: changes in mental health, precautions taken to protect against COVID-19, experiences of symptoms, getting tested for COVID, and willingness to get a vaccine. Important note: the responses for the COV module for the collection periods of September to December have been included on the 2020 annual file but they are not included in the 2019/2020 data file.

Fichier des codes postaux par circonscriptions électorales fédérales [Canada], septembre 2026, Recensement de la population 2021

2026-10-01

Le FCPCEF est un fichier numérique qui établit un lien entre le code postal à six caractères et les circonscriptions électorales fédérales du Canada (également appelées circonscriptions fédérales).

Selon Élections Canada, une circonscription électorale fédérale (CEF) est un endroit ou un territoire dont les habitants sont en droit d’élire un député à la Chambre des communes. Les limites légales et les descriptions des CEF sont du ressort du Directeur général des élections et sont généralement révisées tous les dix ans d’après les résultats du recensement décennal. Selon l’Ordonnance de représentation de 2013, dernière révision des limites des circonscriptions électorales fédérales, il y a 338 CEF au Canada

Certains codes postaux chevauchent les limites d’une ou de plusieurs CEF. La variable « lien unique » indique si le code postal est lié à une ou plusieurs CEF. Les utilisateurs apparient souvent le code postal de leur ensemble de données à la CEF du FCPCEF. Lorsqu’ils effectuent ce jumelage, les utilisateurs doivent se rappeler que le code postal de leurs données peut renvoyer à l’adresse postale d’une personne, et pas nécessairement à son adresse résidentielle. De même, le code postal de l’adresse d’une entreprise n’indique pas nécessairement l’emplacement des activités de l’entreprise.

La date de référence pour les codes postaux inclus dans le FCPCEF est la même date que celle retenue pour les codes postaux compris dans le Fichier de conversion des codes postaux (FCCP) diffusé en même temps que la présente version du FCPCEF

Postal Code Conversion File [Canada], September 2026, Census of Canada 2021

2026-10-01

The Postal Code Conversion File (PCCF) is a digital file which provides a correspondence between the Canada Post Corporation (CPC) six-character postal code and Statistics Canada's standard geographic areas for which census data and other statistics are produced. Through the link between postal codes and standard geographic areas, the PCCF permits the integration of data from various sources. The Single Link Indicator provides one best link for every postal code, as there are multiple records for many postal codes.

New to the June 2022 version, a separate data file is available for retired postal codes. The retired file uses the same record layout as the PCCF file. The same syntax file can be used for both the PCCF data file and the retired data file.

The geographic coordinates attached to each postal code on the PCCF are commonly used to map the distribution of data for spatial analysis (e.g., clients, activities). The location information is a powerful tool for planning, or research purposes.

The geographic coordinates, which represent the standard geostatistical areas linked to each postal code^OM on the PCCF, are commonly used to map the distribution of data for spatial analysis (e.g., clients, activities). The location information is a powerful tool for marketing, planning, or research purposes. In April 1983, the Statistical Registers and Geography Division released the first version of the PCCF, which linked postal codes^OM to 1981 Census geographic areas and included geographic coordinates. Since then, the file has been updated on a regular basis to reflect changes. For this release of the PCCF, the vast majority of the postal codes^OM are directly geocoded to 2016 Census geography while others are linked via various conversion processes. A quality indicator for the confidence of this linkage is available in the PCCF.

Postal Code Federal Riding File [Canada], September 2026, Census of Canada 2021

2026-10-01

The Postal Codes by Federal Ridings File (PCFRF) is a digital file which provides a link between the six- character postal code and Canada’s federal electoral districts (which are also known as federal ridings).

Elections Canada defines a federal electoral district (FED) as any place or territorial area entitled to return a Member of Parliament (MP) to serve in the House of Commons. Federal electoral district legal limits and descriptions are the responsibility of the Chief Electoral Officer, and are usually revised every ten years after the results of the decennial census. There are 338 FEDs in the 2013 Representation Order, the most recent revision of the federal electoral districts limits.

Some postal codes straddle one or more FED boundaries. The ‘unique link’ variable indicates if the postal code is linked to one or more FEDs. Users often link the postal code in their data set to the FED in the PCFRF. When performing this link, users should be aware that the postal code in their data set may represent a mailing address used by a person, not necessarily where the person actually resides. Similarly, a postal code in a business-based mailing address may not necessarily indicate where the business activity took place.

The reference date for postal codes contained in the PCFRF is the same date as the postal codes contained in the Postal Code Conversion File (PCCF) product released concurrently with this version of the PCFRF

Restricted File Access will be granted only to DLI and Odesi Subscribing Institutions.

Labour Force Survey, July 2026 [Canada]

2026-09-29

LFS data are used to produce the well-known unemployment rate as well as other standard labour market indicators such as the employment rate and the participation rate. The LFS also provides employment estimates by industry, occupation, public and private sector, hours worked and much more, all cross-classifiable by a variety of demographic characteristics. Estimates are produced for Canada, the provinces, the territories and a large number of sub-provincial regions. For employees, data on wage rates, union status, job permanency and establishment size are also produced.

These data are used by different levels of government for evaluation and planning of employment programs in Canada. Regional unemployment rates are used by Employment and Social Development Canada to determine eligibility, level and duration of insurance benefits for persons living within a particular employment insurance region. The data are also used by labour market analysts, economists, consultants, planners, forecasters and academics in both the private and public sector.

Statistical activity
Together, four statistical programs tell a more complete story of current labour market events. These programs are: the Labour Force Survey (LFS), the Survey of Employment, Payrolls and Hours (SEPH), Employment Insurance Statistics (EIS), and the Job Vacancy and Wage Survey (JVWS). Every month, the LFS provides timely data on the labour market, including the unemployment rate and demographic analysis. Later on, the SEPH report shows greater detail on non-farm industry employment and earnings and the JVWS supplies preliminary indicators on job vacancies. EIS provides substantial detail on Employment Insurance benefits by geography, socio-demographics and former occupation. Every quarter, the JVWS provides detailed information on job vacancies by occupation and economic region.

Epidemiology of stillbirths and maternal post-discharge outcomes following stillbirths in Uganda: a prospective cohort study

2026-09-29

Background: Stillbirth remains a critical public health challenge in low-resource settings and is a significant cause of perinatal mortality, where gaps in antenatal care, healthcare access, and socioeconomic disparities exacerbate risks. Understanding maternal post-discharge outcomes and identifying modifiable predictors for stillbirths is essential to improve care pathways.

Methods: This prospective cohort study analyzed maternal and perinatal health data from 7131 women who delivered 7359 newborns at the Mbarara and Jinja Regional Referral Hospitals between April, 2022 and September, 2023. A stillbirth was defined as the death of a foetus ≥28 weeks of gestation. Univariate logistic regression models were used to determine potential predictors associated with stillbirth . Odds ratios (ORs) with 95% confidence intervals (CIs) were reported.

Results: Among 7129 women who survived and were discharged post-delivery, 261 (3.7%) experienced a stillbirth. Six-week post-discharge readmission of women of stillborn infants was 8.5% as compared to 3% among those who were discharged with a live newborn. Previous child death was strongly associated with stillbirth (OR: 7.11, 95% CI: 5.5–9.17, p <0.001), followed by transport delays >1 hour (OR: 2.71, 95% CI: 1.95–3.75) and pregnancy-related illnesses (OR: 1.70, 95% CI: 1.30–2.25). Each additional year of maternal age increased odds by 2% (OR: 1.02, 95% CI: 1.00–1.04). Protective factors included adequate antenatal care (4–8 visits) (OR: 0.51, 95% CI: 0.40–0.66) and partner support (OR: 0.72, 95% CI: 0.56–0.95).

Conclusion: Maternal morbidity following stillbirths is high. Furthermore, several demographic, health, and socioeconomic characteristics are strongly associated with stillbirths. Many stillbirths may be prevented following early identification of these characteristics through interventions to ensure expectant mothers receive adequate support during their pregnancy.

Ethics Declaration: This study was approved by Makerere University School of Public Health (MakSPH) Research and Ethics Committee (SPH-2021-177), the Uganda National Council of Science and Technology (UNCST) in Uganda (HS2174ES), and the University of British Columbia in Canada (H21-03709).

Sex and body composition modulate transcutaneous spinal stimulation responses in neurologically healthy adults

2026-09-26

These data files accompany a manuscript submitted for review to eLife. The dataset comprises processed electromyographic (EMG) response measures from 50 participants (P01–P50), each tested across three sessions/visits (V1, V2, V3), yielding 150 files organized as one file per participant per visit (P##_V#_clean). Within each file, every row corresponds to a single measurement window for a given muscle and stimulus (identified by the Muscle, Period, and Interval fields at a specified StimulationIntensity), and the columns report the amplitude of the evoked response (maximum, minimum, peak-to-peak, mean, and standard deviation), its timing (time-to-maximum, time-to-minimum, time-to-first-response, and response latency), and the corresponding pre-stimulus baseline statistics (mean, standard deviation, minimum, and maximum).

Data and code from: Grassland set-asides provide nesting habitat for bumble bees in agroecosystems

2026-09-26

Abstract

Wild bee declines threaten pollination services in agricultural landscapes. The availability of adequate nesting habitat, especially within intensively farmed regions, has been identified as an area where more research is critically needed. We assessed the potential for grassland set-asides (GLSAs), an agricultural diversification practice that temporarily takes fields out of production to cover crop them with grasses and forbs, to provide high-quality nesting habitat for wild bumble bees (Bombus spp.). During the spring of 2023, we surveyed nest-searching queen abundance across multiple agricultural land use types, including GLSAs, in an intensively managed agricultural landscape. Then, during the summer, we mapped worker distributions and performed microsatellite analysis of tarsal DNA to estimate colony abundance across these land use types. Native nest-searching queens were observed more frequently in GLSAs, relative to other land types (while accounting for their overall frequency in the landscape), with queen densities in GLSAs comparable to unmanaged grassy areas and significantly higher than in crop fields, pastures, or roadsides. The area of GLSAs in a landscape was also a strong predictor of native bumble bee worker abundance and supported a higher estimated nest abundance for the species Bombus mixtus, indicating that the positive effects of GLSAs on bumble bees extend beyond the nest site selection phase. Synthesis and applications. Our study demonstrates that GLSAs can provide nesting habitat for bumble bees within intensively managed agroecosystems. To maximize their conservation value and to avoid creating ecological traps, land managers should consider incorporating GLSAs into farming landscapes for the full duration of the colony cycle (i.e., spring queen emergence through late-summer gyne and male production). Moreover, farmers and communities should incorporate knowledge about alternative nesting sites, for example by staggering GLSA schedules at the landscape level, to mitigate the loss of habitat when GLSAs are returned to production.

Lymphedema Night-time Compression Trial

2026-09-26

Background: Lymphedema is a prevalent long-term effect of breast cancer treatment that is associated with reduced quality of life. Observational data support a positive association between the regular application of night-time compression and long-term control of arm lymphedema. The purpose of this study was to examine the efficacy of night-time compression as a self-management strategy for women with chronic breast cancer related lymphedema. Methods/ Design: We conducted a parallel 3-arm, multi-centre randomized fast-track trial. Women were recruited from three centres in Canada and randomized to Group 1: Day-time compression garment alone (standard care), or Group 2: Day-time compression garment + night-time compression bandaging (CB), or Group 3: Day-time compression garment + use of a night-time compression system garment (NCSG). The primary outcome was the change in excess arm volume from baseline to 12 weeks. Following the randomized trial intervention period, participants from all groups used a NCSG from weeks 13 to 24. Results: One hundred and twenty women were enrolled, 118 completed the randomized trial, and 114 completed the 24-week follow-up. Adherence to the application of night-time compression was 95% (±15) and 96% (±11) in the CB and NCSG groups, respectively. Post-intervention, the addition of night-time compression was found to be superior to standard care for both absolute millilitre (p = 0.006) and percent reduction (p = 0.002) in excess arm lymphedema volume. Significant within group changes were seen for quality of life across all groups; however, no between group differences were found (p > 0.05). Discussion: The trial demonstrated a significant improvement in arm lymphedema volume from the addition of night-time compression whether through the application of compression bandaging or use of a night-time compression system garment. Given the benefit and high adherence rates seen in the trial, we recommend early introduction of night-time compression as a self-management strategy for breast cancer related lymphedema.

Data from: North America defies a global trend of reduced vascular plant diversity in extreme environments: Are Asteraceae responsible?

2026-09-25

Abstract

Premise of the study. It is generally assumed that more extreme environments are less habitable for a majority of organisms, leading to a decrease in biodiversity. However, definitions of extremeness are typically based on the abiotic tolerances of specific lineages, and thus may be partly circular and poorly applicable across global biodiversity. Here we test this assumption agnostic to biological definitions of extremeness.

Methods. We use upper and lower extremes of environmental variables on six continents to derive a set of 30 extreme abiotic stress layers that fall within nine extreme stress categories, each expected to affect the survival of terrestrial organisms. We compare these to vascular plant species richness.

Key results. While plant species richness decreases globally where extremes co-occur, the reverse is true in North America, where increased species richness is associated with regions where diverse types of extreme environmental conditions overlap. Data for the largest family of plants (Asteraceae) support this finding in North America, and suggest that the diversity of this family by itself contributes much to this pattern.

Conclusions. Our results demonstrate how insights may be gained through approaches that define environmental extremes agnostic of organismal tolerances. While extreme environments do restrict plant diversity overall, by identifying regions where multiple extreme stressors co-occur, we can detect lineages that prosper under such conditions. Understanding of how extreme conditions have shaped plant diversity across the globe provides a historical context for shifting geographic distributions of extreme environmental conditions in the coming decades and centuries.

A dataset for fall risk prediction and dual task performance evaluation in ecological conditions

2026-09-25

The proposed dataset contains data of 90 healthy older adults who performed single task walking and dual task walking while performing an additional cognitive task. Participants were filmed in the sagittal plane by one or two video cameras, and a pose estimation method was applied to the videos to obtain the position of points of interest during gait. Additional information regarding fall risk was also gathered. This dataset was created with the purpose of exploring the links between fall risk and dual task performance during walking in healthy older adults.

Data from: Spatio-temporal dynamics of ringed seal density and habitat use in the Arctic’s Last Ice Area

2026-09-25

Abstract

Fisheries and Oceans Canada conducted aerial surveys between 2018 and 2024 in both spring and summer to quantify spatio-temporal variation in the density of the most abundant ice-associated mesopredator in the Arctic, ringed seals (Pusa hispida), and to model their habitat use relative to several habitat characteristics. Ringed seal density estimates were calculated per aerial transect for each survey using the standard ratio. The table of ringed seal observations and habitat characteristics extracted along transect segments was used to model the habitat use of ringed seals using Generalized Linear Mixed Models. The density estimates and the habitat characteristics provide an index for monitoring potential future changes in ringed seal habitat use in this ecologically important region of the Arctic and across the broader extent of their range.

National Travel Survey, 2021: Person file [Canada]

2026-09-24

The National Travel Survey (NTS) provides statistics on the activities of Canadian residents related to domestic and international tourism. It was developed to measure the volume, the characteristics and the economic impact of tourism. For the Canadian System of National Accounts, the NTS measures the size of domestic travel in Canada from the demand side.

The NTS was developed to fully replace the Travel Survey of Residents of Canada (TSRC record number 3810) and replace the Canadian resident component of the International Travel Survey (ITS record number 3152). The NTS collects information about the domestic and international travel of Canadian residents.

The person microdata file includes basic socio-demographic information on both travellers and non-travellers. It can be used to produce simple socio-demographic profiles and to calculate travel incidences.

The person microdata file does not provide information on the volume of trips or person-trips taken but rather on the volume of travellers and non-travellers. If a person travelled more than once during the reference period, that person will be counted as a traveller only once.

The National Travel Survey (NTS) was developed to fully replace the Travel Survey of Residents of Canada (TSRC record number 3810) and replace the Canadian resident component of the International Travel Survey (ITS record number 3152). The National Travel Survey collects information about the domestic and international travel of Canadian residents.

The National Travel Survey provides statistics on the activities of Canadian residents related to domestic and international tourism. It was developed to measure the volume, the characteristics and the economic impact of tourism. For the Canadian System of National Accounts, NTS measures the size of domestic travel in Canada from the demand side.

The visit concept is used to measure the number of person-visits to a specific location. The visit file has at least two records per visit location for every person-trip found on the-trip file (origin and destination).

National Travel Survey, 2024: Trip file [Canada]

2026-09-24

The trip file contains trip characteristics, for example, the origin, the main destination, the reason of the trip, the spending, etc. For each respondent on the person file, there is a trip record for every trip reported. If a respondent did not report any trips, there would be no trip records for that respondent on the trip file.

National Travel Survey, 2024: Person file [Canada]

2026-09-24

The person file provides information on travellers and non-travellers, a traveller being a person aged 18 and over who took at least one trip ending in the reference month and a non-traveller being someone who did not take a trip ending in the reference month. Each respondent to the NTS has one record on the person file whether they have travelled within the reference period or not. The person microdata file includes basic socio-demographic information on both travellers and non-travellers. It can be used to produce simple socio-demographic profiles and to calculate travel incidences. For example, what is the age or gender of travellers versus non-travellers? What percentage of the population 55 years of age and over travelled? The person microdata file does not provide information on the volume of trips or person-trips taken but rather on the volume of travellers and non-travellers. If a person travelled more than once during the reference period, that person will be counted as a traveller only once.

CITF SARS-CoV-2 Vaccination Harmonization Protocol

2026-09-24

This repository contains the protocol and supporting metadata schema used to harmonize SARS-CoV-2 vaccination information contributed by studies supported by the COVID-19 Immunity Task Force (CITF). The materials document the standardized variables, permissible values, harmonization-status classifications, and transformation rules applied in preparing the frozen CITF Databank release v1.0. Individual-level participant data are not included.

Harmonization protocol

The primary document is the CITF SARS-CoV-2 Vaccination Harmonization Protocol, version 1.0. It describes:

the scope of vaccination-data harmonization;
data sources and participant-inclusion criteria;
the target harmonized variables;
mapping of study-specific variables to CITF Core Data Elements;
harmonization-status classifications;
the dose-event-level structure of the harmonized dataset;
data-quality and validation procedures; and
governance, access, and versioning requirements.

Metadata schema

The repository includes the CITF vaccination Core Data Element schema, version 1.0. The schema defines six target variables:

participant identifier;
study-reported vaccine-dose number;
vaccination date;
vaccine type;
free-text specification of other vaccine types; and
additional comments associated with the vaccination record.

The schema also documents variable labels, value types, date formats, permissible vaccine-type categories, acceptable data sources, and harmonization instructions.

Dataset structure

The harmonized vaccination dataset is organized at the dose-event level. Each record represents one administered vaccine dose. A participant who received multiple doses is therefore represented by multiple records. Each record contains the participant identifier and, where available, the study-reported dose number, administration date, vaccine type, and supporting free-text information.

Records are linked to participants and to the other CITF harmonized datasets using the participant identifier, which incorporates the study identifier within its structure.

Harmonization rules

During harmonization, study-specific vaccination variables are mapped to the standardized CITF schema. Variables that directly match a target variable are mapped without transformation. Compatible source variables are transformed to the target format according to documented rules.

Study-reported dose numbers are retained and are not reassigned solely on the basis of vaccination dates. When a dose number is not clearly reported, it is recorded as missing. Records are not reordered solely to create an apparently chronological dose sequence.

Distinct vaccination dates are retained even when the interval between doses appears unusual. When conflicting dates are reported for the same dose, both dates may be retained with the dose number set to missing until clarification is received from the contributing study. When different vaccine types are reported for the same dose date, the value from the earliest data-collection event is provisionally retained, subject to confirmation by the contributing study. Information confirmed by the contributing study supersedes these provisional rules.

Quality control

Quality-control procedures include:

validation of participant identifiers;
non-negativity checks for dose numbers;
validation of vaccination dates and date components;
review of permissible vaccine-type categories;
assessment of conflicting information across data-collection events;
detection of duplicate vaccination records; and
review of apparent chronological inconsistencies.

Chronological inconsistencies are flagged for review but do not result in automatic reassignment of study-reported dose numbers. These procedures constitute dataset-level harmonization and quality control and do not independently verify vaccination against external clinical or administrative records.

Data access

Individual-level vaccination data are held under controlled access and are not included in this repository. Access to restricted data requires a formal request to the CITF Data Access Office and is subject to applicable institutional approvals, consent conditions, governance requirements, and data-sharing agreements.

Protocol version: 1.0

CITF Harmonized Databank – Release v1.0

2026-09-24

This metadata record describes Release v1.0 of the harmonized datasets maintained by the COVID-19 Immunity Task Force (CITF) Databank. The release consists of three linkable data domains: the Baseline Questionnaire, Vaccination, and Serology datasets.

The Baseline Questionnaire dataset contains harmonized participant-level demographic, health, COVID-19 exposure, testing, and related questionnaire information. The Vaccination dataset contains repeated dose-level COVID-19 vaccination records. The Serology dataset contains repeated assay-level SARS-CoV-2 antibody measurements and associated assay metadata.

The harmonized datasets were produced from contributing CITF-supported studies using standardized Core Data Elements, study-specific data dictionaries, documented harmonization protocols, and rule-based quality-control procedures. Detailed study-level coverage, dataset characteristics, and bibliographic references are reported in the associated CITF Databank manuscript.

Individual-level data are not publicly deposited in this record because they contain sensitive participant information and are governed by institutional ethics approvals, participant consent, data-sharing agreements, and CITF data-access policies.

Researchers may explore available studies and metadata through the CITF Databank website. Requests for access to controlled individual-level data must be submitted through the CITF Data Access Portal and are subject to administrative and scientific review and completion of the applicable data-access requirements.

This record provides a persistent reference for the frozen Release v1.0 of the CITF harmonized Databank. Supporting harmonization protocols, metadata schemas, validation documentation, governance materials, and reproducible workflow code are available through the related Borealis records.

CITF SARS-CoV-2 Serology Harmonization Protocol

2026-09-24

This repository contains the protocol and supporting documentation used to harmonize SARS-CoV-2 serology data contributed by studies supported by the COVID-19 Immunity Task Force (CITF). The materials document the standardized variables, terminology, permissible values, assay metadata, harmonization-status classifications, and transformation rules applied in preparing the frozen CITF Databank release v1.0. Individual-level participant data are not included.

Harmonization protocol

The primary document is the CITF SARS-CoV-2 Serology Harmonization Protocol, version 2.8. It describes:

the scope of the serology harmonization process;
the target harmonized variables;
the mapping of study-specific variables to CITF Core Data Elements;
harmonization-status classifications;
the structure of the harmonized serology dataset;
data-quality and validation procedures; and
governance, access, and versioning requirements.

The repository also includes the CITF serology Core Data Element schema and supporting serological assay metadata. The reporting guide is included as source-data reporting guidance used by contributing studies.

Dataset structure

The harmonized serology dataset is organized at the result level. Each record represents one assay result for one participant. A participant may therefore have multiple records corresponding to different specimens, assays, or time points.

The target schema includes participant, specimen, and assay identifiers; specimen and assay characteristics; specimen-collection and assay dates; units of measurement; quantitative results; standardized binding antibody units where available; qualitative interpretations; assay measurement limits; and result-level quality-control indicators.

Harmonization and quality control

During harmonization, study-specific serology variables are mapped to the standardized CITF schema. Records are linked to standardized assay metadata using the CITF assay identifier. Quality-control procedures include:

validation of participant, specimen, and assay identifiers;
standardization and validation of dates, units, and categorical values;
review of assay metadata;
assessment of quantitative ranges;
duplicate-record detection; and
evaluation of internal consistency.

These procedures constitute dataset-level harmonization and quality control. They do not represent laboratory re-testing or independent biological validation of assay performance.

Scope limitations

Cell-mediated immunity data are outside the scope of this protocol and are not included in the harmonized serology dataset for Release v1.0. Neutralizing-antibody variables are also excluded from the harmonized dataset for this release.

Data access

Individual-level serology data are held under controlled access and are not included in this repository. Access to restricted data requires a formal request to the CITF Data Access Office and is subject to applicable institutional approvals, consent conditions, governance requirements, and data-sharing agreements.

IndiQ-AVC: Jeu de données clinico-administratives multicentriques sur la prise en charge interdisciplinaire en phase aiguë de l'AVC ischémique au Québec / IndiQ-AVC: Multicenter clinical and administrative dataset on interdisciplinary acute phase management of ischemic stroke in Quebec

2026-09-24

Ces données proviennent d’une étude doctorale au cours de laquelle des informations ont été extraites des dossiers de santé de 132 patients hospitalisés pour un AVC entre le 1er décembre 2022 et le 31 mai 2023 dans trois centres québécois de désignation différente en soins de l’AVC (niveaux 3, 4 et 5). Le présent jeu de données découle de la base de données IndiQ-AVC, développée à partir d’un ensemble d’indicateurs de qualité cliniques et organisationnels sélectionnés à la suite d’un examen de la portée et d’un processus de consensus Delphi auprès d’experts. La base de données IndiQ-AVC comprend à la fois des données cliniques (liées aux patients), comme les caractéristiques sociodémographiques, les résultats de santé et les facteurs de risque, ainsi que des données administratives (de nature organisationnelle ou économique), notamment des informations sur les trajectoires de soins, les délais de prise en charge et la durée du séjour. Les données sont issues de huit catégories d'indicateurs : les caractéristiques sociodémographiques, les caractéristiques cliniques, les facteurs de risque, les trajectoires de soins et les délais, les évaluations, les complications survenues durant l’hospitalisation, les données au congé, ainsi que l’orientation et l’enseignement au congé. Cette base de données a contribué à la production de deux publications scientifiques. La première portait sur la qualité des données de santé, notamment l’ampleur des données manquantes et les types de variables pouvant être mesurées à partir des dossiers de santé. La seconde présentait une évaluation descriptive de l’adhésion aux indicateurs de qualité ainsi que des résultats associés à la prise en charge interdisciplinaire en phase aiguë de l’AVC ischémique. // Des considérations éthiques empêchent la mise à disposition publique de ces données. Vous pouvez cliquer sur « Contacter le ou la propriétaire » pour en faire la demande, sous certaines conditions.These data originate from a doctoral study in which information was extracted from the health records of 132 patients hospitalized for stroke between December 1, 2022, and May 31, 2023, in three Quebec stroke centres with different levels of stroke care designation (levels 3, 4, and 5). The present dataset is derived from the IndiQ-AVC database, which was developed based on a set of clinical and organizational quality indicators selected through a scoping review and a Delphi consensus process involving experts. The IndiQ-AVC database includes both clinical (patient-related) data, such as sociodemographic characteristics, health outcomes, and risk factors, and administrative (organizational and economic) data, including information on care trajectories, treatment delays, and length of stay. The data come from eight categories of indicators: sociodemographic characteristics, clinical characteristics, risk factors, care trajectories and delays, assessments, in-hospital complications, discharge data, and discharge referrals and education. This database contributed to the production of two scientific publications. The first focused on the quality of health data, particularly the extent of missing data and the types of variables that can be measured using health records. The second presented a descriptive evaluation of adherence to quality indicators and outcomes associated with interdisciplinary acute ischemic stroke care. // Ethical considerations prevent data from being publicly available.

cross-file record linkage;
wide-to-long restructuring of repeated measurements; and
PostgreSQL operations used to write harmonized outputs to the relational database.

The code was developed using R version 4.5.0. File paths and database connection parameters are represented by configurable placeholders and must be adapted to the user’s local environment. Database credentials, internal server addresses, and participant-level data are not included in the repository.

Validation rules

The repository includes documentation of the rule-based checks applied during harmonization and validation. The checks are organized into six stages:

data-ingestion checks;
schema and Core Data Element alignment;
serology metadata and plausibility checks;
internal-consistency checks;
cross-study comparability assessment; and
documentation, provenance, and version control.

For each rule, the documentation describes the acceptance criterion and the action taken when the criterion is not met. These procedures constitute dataset-level quality control. They do not represent laboratory re-testing or independent biological validation of assay performance.

Metadata schemas

The repository includes the CITF Core Data Element schemas for the baseline questionnaire, vaccination, and serology harmonized domains. The schemas define the relevant variables, labels, value types, units, and permitted categories. Supporting serological assay metadata and code lists are included where relevant.

Study-specific source variables are mapped to the CITF Core Data Elements according to defined rules for recoding, non-negativity, range constraints, date-component validation, duplicate handling, and assessment of the chronological consistency of repeated events. Study-reported event and vaccination-dose numbers are retained and are not reassigned solely on the basis of event dates.

Data management and access

Original study datasets were transferred through McGill University’s secure file-exchange environment, processed using the R-based harmonization workflow, and stored in a PostgreSQL relational database to support structured data management and release versioning.

Access to restricted participant-level datasets requires a formal request to the CITF Data Access Office and is subject to applicable institutional approvals, consent conditions, governance requirements, and data-sharing agreements.

health conditions; and
COVID-19 vaccination information reported through the baseline questionnaire.

Dataset structure

The harmonized baseline questionnaire dataset is organized at the participant level. Each record represents one participant’s baseline information from the initial questionnaire or chart-review data-collection event. Where relevant information was collected through more than one source instrument, the information is consolidated into a single baseline record.

Records are linked to participants and to the other CITF harmonized datasets using the participant identifier. A separate study identifier is retained to support study identification and data provenance.

Harmonization and quality control

During harmonization, study-specific questionnaire variables are mapped to the standardized CITF schema. Variables that directly match a target variable are mapped without transformation. Compatible source variables are transformed to the target format according to documented rules. Variables that were not collected or could not be validly mapped are assigned the applicable harmonization status.

Quality-control procedures include:

validation of participant and study identifiers;
assessment of record uniqueness at the participant level;
standardization of missing values and categorical values;
numeric range and non-negativity checks;
validation of date values and date components;
duplicate-record detection; and
assessment of internal consistency.

These procedures constitute dataset-level harmonization and quality control. They do not replace verification against the contributing studies’ original source records.

This data bundle contains the three datasets used to produce Figures 2–4 of the MSC thesis of F. Girard at UQTR. It combines published hearing-threshold measurements for larvae of 22 fish species, classified into four auditory-specialization groups, with field data from experiments examining larval responses to sound treatments. The field datasets include information on larval abundance, body length, taxonomic or auditory group, sampling site, and sound treatment under peak- and low-abundance conditions. Together, these datasets support analyses of how larval size and auditory specialization relate to hearing capacity and responses to anthropogenic sounds.

Data Quality Flags for ACE-FTS Level 2 Version 5.3 Data Set

2026-09-23

Data quality flags generated for the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) Level 2 (L2) version 5.3 data products. These data quality flags are generated using the technique described in Sheese et al. (2015). One netCDF file is produced for each species, isotopologue or parameter retrieved from the ACE-FTS spectra for version 5.3. Each file contains the data quality flags organized by occultation (orbit number and occultation type). Note, the ACE-FTS Level 2 version 5.3 profiles are not included in these files. The data quality flag files are updated monthly as new Level 2 version 5.3 data are produced for ACE-FTS.

Supporting Data for “An Evidence-Informed Framework for Prioritizing Lighting Design in Dementia Care Environments”
