   The COVID-19 pandemic has dramatically altered family life in the United States. Over the long duration of the pandemic, parents had to adapt to shifting work conditions, virtual schooling, the closure of daycare facilities, and the stress of not only managing households without domestic and care supports but also worrying that family members may contract the novel coronavirus. Reports early in the pandemic suggest that these burdens have fallen disproportionately on mothers, creating concerns about the long-term implications of the pandemic for gender inequality and mothers’ well-being. Nevertheless, less is known about how parents’ engagement in domestic labor and paid work has changed throughout the pandemic, what factors may be driving these changes, and what the long-term consequences of the pandemic may be for the gendered division of labor and gender inequality more generally.
   
   The Study on U.S. Parents’ Divisions of Labor During COVID-19 (SPDLC) collects longitudinal survey data from partnered U.S. parents that can be used to assess changes in parents’ divisions of domestic labor, divisions of paid labor, and well-being throughout and after the COVID-19 pandemic. The goal of SPDLC is to understand both the short- and long-term impacts of the pandemic for the gendered division of labor, work-family issues, and broader patterns of gender inequality.
   
   Survey data for this study is collected using Prolifc (www.prolific.co), an opt-in online platform designed to facilitate scientific research. The sample is comprised U.S. adults who were residing with a romantic partner and at least one biological child (at the time of entry into the study). In each survey, parents answer questions about both themselves and their partners. Wave 1 of SPDLC was conducted in April 2020, and parents who participated in Wave 1 were asked about their division of labor both prior to (i.e., early March 2020) and one month after the pandemic began. Wave 2 of SPDLC was collected in November 2020. Parents who participated in Wave 1 were invited to participate again in Wave 2, and a new cohort of parents was also recruited to participate in the Wave 2 survey. Wave 3 of SPDLC was collected in October 2021. Parents who participated in either of the first two waves were invited to participate again in Wave 3, and another new cohort of parents was also recruited to participate in the Wave 3 survey. This research design (follow-up survey of panelists and new cross-section of parents at each wave) will continue through 2024, culminating in six waves of data spanning the period from March 2020 through October 2024. An estimated total of approximately 6,500 parents will be surveyed at least once throughout the duration of the study.
   
   SPDLC data will be released to the public two years after data is collected; Waves 1 and 2 are currently publicly available. Wave 3 will be publicly available in October 2023, with subsequent waves becoming available yearly. Data will be available to download in both SPSS (.sav) and Stata (.dta) formats, and the following data files will be available: (1) a data file for each individual wave, which contains responses from all participants in that wave of data collection, (2) a longitudinal panel data file, which contains longitudinal follow-up data from all available waves, and (3) a repeated cross-section data file, which contains the repeated cross-section data (from new respondents at each wave) from all available waves. Codebooks for each survey wave and a detailed user guide describing the data are also available. Response Rates: Of the 1,157 parents who participated in Wave 1, 828 (72%) also participated in the Wave 2 study. Presence of Common Scales: The following established scales are included in the survey:
   

   • Self-Efficacy, adapted from Pearlin's mastery scale (Pearlin et al., 1981) and the Rosenberg self-esteem scale (Rosenberg, 2015) and taken from the American Changing Lives Survey
   • Communication with Partner, taken from the Marriage and Relationship Survey (Lichter & Carmalt, 2009)
     
   • Gender Attitudes, taken from the National Survey of Families and Households (Sweet & Bumpass, 1996)
     
   • Depressive Symptoms (CES-D-10)
   • Stress, measured using Cohen's Perceived Stress Scale (Cohen, Kamarck, & Mermelstein, 1983)
     

   Full details about these scales and all other items included in the survey can be found in the user guide and codebook
   The second wave of the SPDLC was fielded in November 2020 in two stages. In the first stage, all parents who participated in W1 of the SPDLC and who continued to reside in the United States were re-contacted and asked to participate in a follow-up survey. The W2 survey was posted on Prolific, and messages were sent via Prolific’s messaging system to all previous participants. Multiple follow-up messages were sent in an attempt to increase response rates to the follow-up survey. Of the 1,157 respondents who completed the W1 survey, 873 at least started the W2 survey. Data quality checks were employed in line with best practices for online surveys (e.g., removing respondents who did not complete most of the survey or who did not pass the attention filters). After data quality checks, 5.2% of respondents were removed from the sample, resulting in a final sample size of 828 parents (a response rate of 72%).
   
   In the second stage, a new sample of parents was recruited. New parents had to meet the same sampling criteria as in W1 (be at least 18 years old, reside in the United States, reside with a romantic partner, and be a parent living with at least one biological child). Also similar to the W1 procedures, we oversampled men, Black individuals, individuals who did not complete college, and individuals who identified as politically conservative to increase sample diversity. A total of 1,207 parents participated in the W2 survey. Data quality checks led to the removal of 5.7% of the respondents, resulting in a final sample size of new respondents at Wave 2 of 1,138 parents.
   
   In both stages, participants were informed that the survey would take approximately 20 minutes to complete. All panelists were provided monetary compensation in line with Prolific’s compensation guidelines, which require that all participants earn above minimum wage for their time participating in studies.
   To be included in SPDLC, respondents had to meet the following sampling criteria at the time they enter the study: (a) be at least 18 years old, (b) reside in the United States, (c) reside with a romantic partner (i.e., be married or cohabiting), and (d) be a parent living with at least one biological child. Follow-up respondents must be at least 18 years old and reside in the United States, but may experience changes in relationship and resident parent statuses. Smallest Geographic Unit: U.S. State

   To help provide estimates that are more representative of U.S. partnered parents, the SPDLC includes sampling weights. Weights can be included in statistical analyses to make estimates from the SPDLC sample representative of U.S. parents who reside with a romantic partner (married or cohabiting) and a child aged 18 or younger based on age, race/ethnicity, and gender. National estimates for the age, racial/ethnic, and gender profile of U.S. partnered parents were obtained using data from the 2020 Current Population Survey (CPS). Weights were calculated using an iterative raking method, such that the full sample in each data file matches the nationally representative CPS data in regard to the gender, age, and racial/ethnic distributions within the data. This variable is labeled CPSweightW2 in the Wave 2 dataset, and CPSweightLW2 in the longitudinal dataset (which includes Waves 1 and 2). There is not a weight variable included in the W1-W2 repeated cross-section data file.

2. Pandemics & people: Designing a virtual epidemic event for immersive, connected, and playful participation in an infectious disease outbreak.

   Fields, D. A. ( January 2022 , Educational designer)

   Researchers and educators have identified an urgent need for more rigorous teaching and learning about epidemiology topics and practices, such as engaging in behaviors that prevent the spread of viral disease such as COVID-19. Responding to this need, we designed a virtual epidemic as a special event hosted in a virtual world. In this paper we share the strategic, tactical, and detailed design of the SPIKEY-20 virtual epidemic and data that reflects back on the design in terms of player participation. Reflecting on the design, we ask: What kinds of players participated in the SPIKEY-20 virtual epidemic? How did players engage in designed activities (i.e., preventive measures, information seeking)? In what ways were players influenced by the concurrent real world pandemic of COVID-19? In the discussion we consider the potential connection points between real-life and virtual public health behaviors, new possibilities of classroom participation and teacher support for such a virtual event, and future design considerations for virtual epidemics.

3. Distinguishing the Effect of Time Spent at Home during COVID-19 Pandemic on the Mental Health of Urban and Suburban College Students Using Cell Phone Geolocation

   https://doi.org/10.3390/ijerph19127513  

   Ayranci, Pelin ; Bandera, Cesar ; Phan, NhatHai ; Jin, Ruoming ; Li, Dong ; Kenne, Deric ( June 2022 , International Journal of Environmental Research and Public Health)

   The aim of this study was to assess the correlation of depression and anxiety with time spent at home among students at two universities—one urban and the other suburban—during the COVID-19 pandemic. Methods: Geolocation data from the smartphones of 124 participants were collected between February 2021 and May 2021. The level of depression was estimated by the PHQ-9 and PHQ-2 screening tools, and anxiety scores were estimated by the GAD-2 and GAD-7 screening tools. Results: 51% of participants in the PHQ-9 surveys indicated mild to severe depression. Participants spent on average 75% of their time at home during COVID. Time spent at home had a positive correlation with the mental health of urban students but a negative correlation with suburban students. The relation between the time at home with mental health was stronger among female participants than among male participants. Correlations between female depression, anxiety, and time at home were significant. Conclusions: Lockdown and distance learning contributed to the high levels of depression in university students. This research highlights the importance of time spent at home for mental health being during the pandemic and the importance of distinguishing between urban and suburban settings when formulating public health recommendations. Quality of time spent at home versus time spent outside differentiated the mental well-being of students located in different environments. Staying at home may be recommended for students without access to safe outdoor places as it is associated with lower levels of depression.

4. Study on U.S. Parents' Divisions of Labor During COVID-19, Waves 1-3

5. Software Environments in Binder Containers

   https://doi.org/10.5281/zenodo.4891790  

   Shaffer, Tim ; Chard, Kyle ; Thain, Douglas ( January 2021 , Zenodo)

   Binder is a publicly accessible online service for executing interactive notebooks based on Git repositories. Binder dynamically builds and deploys containers following a recipe stored in the repository, then gives the user a browser-based notebook interface. The Binder group periodically releases a log of container launches from the public Binder service. Archives of launch records are available here. These records do not include identifiable information like IP addresses, but do give the source repo being launched along with some other metadata. The main content of this dataset is in the binder.sqlite file. This SQLite database includes launch records from 2018-11-03 to 2021-06-06 in the events table, which has the following schema.

   CREATE TABLE events( version INTEGER, timestamp TEXT, provider TEXT, spec TEXT, origin TEXT, ref TEXT, guessed_ref TEXT ); CREATE INDEX idx_timestamp ON events(timestamp);

   • version indicates the version of the record as assigned by Binder. The origin field became available with version 3, and the ref field with version 4. Older records where this information was not recorded will have the corresponding fields set to null.
   • timestamp is the ISO timestamp of the launch
   • provider gives the type of source repo being launched ("GitHub" is by far the most common). The rest of the explanations assume GitHub, other providers may differ.
   • spec gives the particular branch/release/commit being built. It consists of <github-id>/<repo>/<branch>.
   • origin indicates which backend was used. Each has its own storage, compute, etc. so this info might be important for evaluating caching and performance. Note that only recent records include this field. May be null.
   • ref specifies the git commit that was actually used, rather than the named branch referenced by spec. Note that this was not recorded from the beginning, so only the more recent entries include it. May be null.
   • For records where ref is not available, we attempted to clone the named reference given by spec rather than the specific commit (see below). The guessed_ref field records the commit found at the time of cloning. If the branch was updated since the container was launched, this will not be the exact version that was used, and instead will refer to whatever was available at the time (early 2021). Depending on the application, this might still be useful information. Selecting only records with version 4 (or non-null ref) will exclude these guessed commits. May be null.

   The Binder launch dataset identifies the source repos that were used, but doesn't give any indication of their contents. We crawled GitHub to get the actual specification files in the repos which were fed into repo2docker when preparing the notebook environments, as well as filesystem metadata of the repos. Some repos were deleted/made private at some point, and were thus skipped. This is indicated by the absence of any row for the given commit (or absence of both ref and guessed_ref in the events table). The schema is as follows.

   CREATE TABLE spec_files ( ref TEXT NOT NULL PRIMARY KEY, ls TEXT, runtime BLOB, apt BLOB, conda BLOB, pip BLOB, pipfile BLOB, julia BLOB, r BLOB, nix BLOB, docker BLOB, setup BLOB, postbuild BLOB, start BLOB );

   Here ref corresponds to ref and/or guessed_ref from the events table. For each repo, we collected spec files into the following fields (see the repo2docker docs for details on what these are). The records in the database are simply the verbatim file contents, with no parsing or further processing performed.

   • runtime: runtime.txt
   • apt: apt.txt
   • conda: environment.yml
   • pip: requirements.txt
   • pipfile: Pipfile.lock or Pipfile
   • julia: Project.toml or REQUIRE
   • r: install.R
   • nix: default.nix
   • docker: Dockerfile
   • setup: setup.py
   • postbuild: postBuild
   • start: start

   The ls field gives a metadata listing of the repo contents (excluding the .git directory). This field is JSON encoded with the following structure based on JSON types:

   • Object: filesystem directory. Keys are file names within it. Values are the contents, which can be regular files, symlinks, or subdirectories.
   • String: symlink. The string value gives the link target.
   • Number: regular file. The number value gives the file size in bytes.

   CREATE TABLE clean_specs ( ref TEXT NOT NULL PRIMARY KEY, conda_channels TEXT, conda_packages TEXT, pip_packages TEXT, apt_packages TEXT );

   The clean_specs table provides parsed and validated specifications for some of the specification files (currently Pip, Conda, and APT packages). Each column gives either a JSON encoded list of package requirements, or null. APT packages have been validated using a regex adapted from the repo2docker source. Pip packages have been parsed and normalized using the Requirement class from the pkg_resources package of setuptools. Conda packages have been parsed and normalized using the conda.models.match_spec.MatchSpec class included with the library form of Conda (distinct from the command line tool). Users might want to use these parsers when working with the package data, as the specifications can become fairly complex.

   The missing table gives the repos that were not accessible, and event_logs records which log files have already been added. These tables are used for updating the dataset and should not be of interest to users.
