title: Replication Package for "Why and How Developers Maintain Smart Contracts"

description: This repository contains the replication package for "Why and How Developers Maintain Smart Contracts".Smart contracts, i.e., self-executing contracts written in code, have gained popularity in recent years due to the introduction of blockchain technology. These contracts are executed automatically when certain conditions are met, and, once deployed, they can not be modified. This presents issues when errors are found or updates are needed. Previous research has mainly focused on introducing approaches and tools for detecting bugs or vulnerabilities in smart contracts. However, it is unclear if these are the only maintenance-related operations developers perform. In this paper, we aim to understand why and how developers maintain smart contracts. We run a qualitative analysis on 590 commits from 14 open-source smart contract repositories written in Solidity, the most popular programming language for smart contracts. We analyze the commit messages, related issues, and the changes made to understand what triggered changes. Then, we examine how developers changed the source code. As a result, we define two taxonomies: One reporting the reasons for the maintenance and one regarding the patterns of modifications. Our findings suggest that smart contract maintenance is often focused on improving the internal quality of the scripts (40% of the cases), and that many changes still aim to fix bugs, despite the several approaches available for detecting them beforehand. We provide several lessons learned that will allow researchers to focus on what developers do.

title: Low Voltage DC Circuit Breaker Metal Oxide Varistor Test Data Set

description: The shared data is from a designed LVDCCB MOV test platform. It conducts repeated tests on the LVDCCB, so not only test data but also component degradations and failure modes could be learned. The shared data set is standard waveforms of an LVDCCB. The setup and its control scheme is introduced in the research article. These data are examplary, showing typical shapes of LVDCCB waveforms. The data are captured without snubber branch of the LVDCCB, which is added later for consistency.

title: IPUMS USA: Version 14.0

description: IPUMS USA contains harmonized census and American Community Survey (ACS) data from 1790 to the present. For the period 1850 to 1940, IPUMS includes 100% of individuals in the decennial censuses. For the period 1950 to 2010, we have public use samples of decennial censuses. For the period since 2000, IPUMS provides annual ACS public use samples. The available information in the censuses and ACS varies by year, but generally includes basic housing data (type of housing, household appliances, and housing characteristics), demographic data (age, race, sex, marital status, and relationship to the head of household), economic data (occupation, industry, income, work status), and other individual characteristics (migration, disability, veteran status). For the period 1790 to 1840, IPUMS includes household level records for 100% of households. IPUMS USA is available through an online data access system free of charge to registered users at usa.ipums.org.

title: IPUMS USA - FSRDC: Version 2.0

description: IPUMS harmonized decennial census data are now available in the Federal Statistical Research Data Centers (FSRDCs). FSRDCs provide necessary security for handling confidential data, allowing the Census Bureau to make non-public versions of decennial data available for research. The collection consists of over one billion person records and 400 million household records. In addition to the large size of the collection, these data are invaluable because the files provide far greater geographic detail than is available in public-use census microdata. IPUMS USA has collaborated with the Census Bureau to convert restricted microdata from the decennial censuses of 1960 through 2000 into IPUMS format. IPUMS provides standardized variable coding over time, making it far easier for researchers to compare census years. The standardized codes in the FSRDC version match public IPUMS codes, although in some cases the FSRDC version has more detail. The data also includes IPUMS-specific variables, such as family interrelationship variables which identify spouses and children present in the household and help researchers leverage complex household information and integrated geographic variables that facilitate comparisons of consistently defined places over time. The availability of IPUMS-format data allows researchers to develop and test their analyses and data transformations using freely-available public data and to make the most efficient use of their time working inside the FSRDC.

title: IPUMS Linked Representative Samples, 1850-1930

description: The IPUMS Linked Representative Samples links records from the 1880 complete-count database to 1% samples of the 1850 to 1930 U.S. censuses of the population. Data samples have been produced for 7 pairs of years: 1850-1880, 1860-1880, 1870-1880, 1880-1900, 1880-1910, 1880-1920, and 1880-1930. Each of these contains three independent linked samples: one of men, one of women, and one of married couples. This final release of the database supersedes the preliminary version that was made available beginning in August 2008.

title: IPUMS Enslaved Population of 1850-1860

description: The IPUMS 1850-1860 Slave Samples are a series of six samples taken from the 1850 and 1860 Censuses of Slave Inhabitants. In both 1850 and 1860, the United States census contained two population schedules. Schedule 1 enumerated details of the free population, while Schedule 2 enumerated details of the slave population. Samples from Schedule 1 of the 1850 and 1860 censuses are available at the main IPUMS site (https://usa.ipums.org/usa/). The Slave PUMS provides the first nationally-representative samples of Schedule 2, the Census of Slave Inhabitants, as well as the first nationally-representative sample linking data from the Slave Schedules to data from the Free Population Schedules. Relatively few questions included in the Census of Slave Inhabitants: schedules from both years asked slaves’ age, sex, color, and disabilities including whether deaf, dumb, blind, insane or idiotic. Enumerators were allowed to record slaves’ names in the 1860 census if the slave was over 100 years of age. Slaveholders also provided information about the number of slaves who had been manumitted or escaped in the prior year. In 1860, the number of houses provided to slaves on the slaveholding was also tallied.

title: IPUMS Full Count Datasets of the 1850 and 1860 Censuses of the Enslaved Population of the United States: Version 2.0

description: The United States 1850 and 1860 censuses included two population schedules: Schedule 1 was for the nation’s free inhabitants (86.2% of the total population in 1850 and 87.4% of the total in 1860), while Schedule 2 was for the nation’s “slave inhabitants” (13.8% and 12.6% of the total population in 1850 and 1860, respectively). IPUMS full count datasets for the free population in 1850 and 1860 constructed using information collected in Schedule 1 are available at the main IPUMS site. The IPUMS Full Count Datasets of the 1850 and 1860 Censuses of the Enslaved Population are based on information collected in Schedule 2, which included relatively few questions. In both years, enumerators recorded each enslaved person’s age, sex, color, and disabilities, but not their name, occupation, birthplace, literacy and other information as they did for free individuals in Schedule 1. At the slaveholding level, enumerators also recorded each slaveholder’s name, the number of enslaved persons in the holding who had been manumitted in the prior year, and the number who had escaped and remained fugitive in the prior year. In 1860, the number of houses provided to enslaved individuals on the slaveholding was also recorded. Unfortunately, information on disabilities, manumissions, fugitives, and houses were incompletely captured in the construction of the full count datasets. Both datasets include several constructed variables useful for researchers, such as holding size and number of slaveholders. Where they could be determined using automated linking algorithms, the IPUMS historical identifier of each slaveholder is included in both datasets, allowing users to link approximately 84% of slaveholders in 1850 to their records in the IPUMS full count dataset for the free population and approximately 80% of slaveholders in 1860. The IPUMS Full Count Datasets of the 1850 and 1860 Censuses of the Enslaved Population replace the version 1.0 sample datasets, although users interested in disabilities, manumissions, fugitives, and houses should consult the earlier sample datasets, which captured this information more consistently.

title: IPUMS-USA 1790-1840 Household-Level Full Count Data: Version 1.0

description: The IPUMS-USA 1790-1840 Full Count Data is available as household-level and county-level datasets for each decennial census year and for the combined years, 1790-1840. This data was made available to researchers through IPUMS from our collaboration with Ancestry.com. The U.S. Census data for 1790-1840 consists of household-level data for the United States at the time of enumeration. There is no individual-level data available in these years, and the detail of household data is largely dependent on the particular census year. In contrast to later U.S. censuses, these historical censuses named only the head of the household and tallied household totals attached to that. For this reason, person-level information is not available, and information about total persons can only be tabulated using household totals. All of the years have missing data, and in some cases, whole states are missing. Thus, the household-level microdata does not always match the published county-level totals. To help identify the missing areas and other issues in the data, county-level summary data is also available. Each county-level variable gives the total from published figures for that county. The data can be merged onto the household-level data files using YEAR, STATEICP, and COUNTY. The county-level datasets are from the ICPSR Study 2896, Part 1-6, which is also available via IPUMS NHGIS

title: IPUMS Full Count Datasets of the 1850, 1860, 1870, and 1880 Censuses of Mortality

description: In 1850, 1860, 1870, and 1880, the U. S. Census Office conducted a census of mortality in conjunction with the population censuses. Households enumerated on the free population census (1850-1880) and slaveholdings enumerated on the enslaved population census (1850-1860) were to report information pertaining to individuals who died in the year prior to the census. Information collected included each decedent's name, age, marital status, month of death, and cause of death. These IPUMS datasets are based on manuscript returns retained by state and local archives. Not all records survive. Coverage varies by census year, state, and locality, with the greatest coverage in the 1860 dataset (98.2% of the enumerated decedents) and lowest coverage in the 1870 dataset (85.3% of the enumerated decedents). The combined four datasets provide information on 1,829,279 decedents. Where they could be determined using automated linking algorithms, the 1870 and 1880 datasets include the IPUMS historical identifier of the household head of the decedent's household of origin.
