title: An assemblage-level comparison of genetic diversity and population genetic structure between island and mainland ant populations

description: Island biotas provide unparalleled opportunities to examine evolutionary
 processes. Founder effects and bottlenecks, for example, typically
 decrease genetic diversity in island populations, while selection for
 reduced dispersal can increase population structure. Given that support
 for these generalities mostly comes from single-species analyses,
 assemblage-level comparisons are needed to clarify how (i) colonization
 affects the gene pools of interacting insular organisms, and (ii) patterns
 of genetic differentiation vary within assemblages of organisms. Here, we
 use genome-wide sequence data from ultraconserved elements (UCEs) to
 compare genetic diversity and population structure of mainland and island
 populations of nine ant species in coastal southern California with
 respect to genetic diversity and population structure. As expected, island
 populations (from Santa Cruz Island) had lower than expected
 heterozygosity and Watterson’s theta compared to mainland populations
 (from the Lompoc Valley). Island populations, however, exhibited smaller
 genetic distances among samples, indicating less population subdivision
 and a higher capacity for dispersal compared to mainland populations.
 Within the focal assemblage, pairwise Fst values revealed pronounced
 interspecific variation in mainland-island differentiation, which
 increases with gyne body size. Our results reveal differences in genetic
 diversity and population genetic structure across an assemblage of
 interacting species, and illuminate general patterns of insularization in
 ants. Compared to single-species studies, our analysis of nine species
 pairs from the same island-mainland system offers a powerful approach to
 studying fundamental evolutionary processes.

title: Data from: Redesign of a life cycle figure improves student conceptions of ecology and evolution

description: Life cycle diagrams communicate the developmental life stages of an
 organism. Design choices may inadvertently communicate additional
 information about survivorship rates, genetic variation, and
 microevolutionary change. In this controlled experiment, we randomly
 assigned one of three life cycle diagrams to 684 college students. Each
 figure included identical life stages of a fictitious organism’s
 development but differed in 1) number of offspring (single or multiple)
 and 2) layout (cyclical or linear). Each participant could reference the
 figure when answering questions about organism survival, variation among
 offspring, and variation between generations. Students scored 21–37%
 higher on questions about survivorship when the available diagram included
 multiple offspring. Students scored 19–30% higher on questions about
 microevolution when the diagram layout was linear. Overall, students who
 received the figure with a linear layout and multiple offspring earned the
 highest average score (54.5%, or 3.3 of 6 questions) on the assessment,
 while students with the traditional figure (cyclical layout with single
 offspring) scored the lowest average (26.1%, or 1.6 of 6 questions). These
 results suggest that figure design affects student interpretations and may
 assist student learning about ecology and evolution concepts and common
 misconceptions.

 [https://doi.org/10.5061/dryad.tb2rbp08t](https://doi.org/10.5061/dryad.tb2rbp08t) These data are student responses to an 8-question survey of survivorship, phenotypic variation, and microevolution topics. Each student was randomly assigned one of three life cycle figures: a cyclical layout with single offspring (CS), a cyclical layout with multiple offspring (CM), or a linear layout with multiple offspring (LM). For questions of survivorship and cohort variation, we compared CS to CM (isolating the variable number of offspring). For questions about intergenerational change and microevolution, we compared CM to LM (isolating the layout variable). ## Description of the data and file structure The first tab in the data file is the raw data. The second tab includes the processed total score on the 6-question assessment. The next 6 tabs are processed responses to each question. The last two tabs are the data for two descriptional questions, without correct answers and not included in the total score. Columns indicate treatments (CS, CM, or LM). Each row is one participant's response. Cells that contain "n/a" were left blank by participants when they submitted their responses.

title: The Impact of Social Media Political Activists on Voting Patterns.

description: The data investigates how social media affects general voting patterns. Unlike previous studies investigating whether citizens’ use of social media affects political participation, this paper considers the connections that social media users have with political activists on social media, and how this connectedness influences general voting patterns, using data from Ghana. With contemporary theoretical perspectives and exploratory techniques, trends from past literature are presented, from a social media-based propagated survey with 420 valid responses. Structural equation modeling (SEM) was used to test the conceptual model, which demonstrates that the connectedness with political and social media activists is significant and positively influences modifications in voting patterns. Online political participation and political affect also present an effect on voting patterns. The relationship between connections with social media political activists and online political participation, is significant, as indicated by strong covariance observed in the model. The multigroup analysis results also enable some cultural and social issues to shape the phenomena for further investigation.

title: Cast Vote Records: A Database of Ballots from the 2020 U.S. Election

description: Ballots are the core records of elections. Electronic records of actual ballots cast (&lt;i&gt;cast vote records&lt;/i&gt;) are available to the public in some jurisdictions. However, they have been released in a variety of formats and have not been independently evaluated. Here we introduce a database of cast vote records from the 2020 U.S. general election. We downloaded publicly available unstandardized cast vote records, standardized them into a multi-state database, and extensively compared their totals to certified election results. Our release includes vote records for President, Governor, U.S. Senate and House, and state upper and lower chambers – covering 42.7 million voters in 20 states who voted for more than 2,200 candidates. This database serves as a uniquely granular administrative dataset for studying voting behavior and election administration. Using this data, we show that in battleground states, 1.9 percent of solid Republicans (as defined by their congressional and state legislative voting) in our database split their ticket for Joseph Biden, while 1.2 percent of solid Democrats split their ticket for Donald Trump.
description: <b>Usage Notes</b>: Please read the included data descriptor (or associated publication in SciData) before interpreting this data. In particular, please note that discrepancies in cast vote records versus reported returns should <i>not</i> be considered as sufficient evidence for election misconduct.

title: Replication Data for: The war that wasn't there? Framing Italy’s “peace mission” in Afghanistan

description: Factors as culture, values and symbols are crucial to understand the 
evolution of the Italian foreign and defence policy. However, scholars’ 
attention to cultural variables in the study of Italian defence policies still leaves many gaps. This paper is a contribution towards closing such gap. Since the end of the Cold War Italian troops have been constantly engaged in military operations abroad spreading a “peacekeeper image” of Italy in the international arena. The aim of this work is to investigate the features and the evolution of the main strategic narratives 
adopted by political leaders to interpret the Italian military involvement in Afghanistan. How did politicians craft strategic narratives on the Afghan mission? How did these story lines influence public opinion during the conflict? How can we explain the drop of consensus occurred? In order to answer these questions this paper relies on polls and content analysis of parliamentary debates (2001-2011).

title: Linear servomotor probe drive system with real-time self-adaptive position control for the Alcator C-Mod tokamak

description: A new servomotor drive system has been developed for the horizontal reciprocating probe on the Alcator C-Mod tokamak. Real-time measurements of plasma temperature and density—through use of a mirror Langmuir probe bias system—combined with a commercial linear servomotor and controller enables self-adaptive position control. Probe surface temperature and its rate of change are computed in real time and used to control probe insertion depth. It is found that a universal trigger threshold can be defined in terms of these two parameters; if the probe is triggered to retract when crossing the trigger threshold, it will reach the same ultimate surface temperature, independent of velocity, acceleration, or scrape-off layer heat flux scale length. In addition to controlling the probe motion, the controller is used to monitor and control all aspects of the integrated probe drive system.
