... This is the data and the script for the analysis of a manuscript submitted to be published. Abstract: Embodied cognition frameworks suggest a direct link between sensorimotor experience and cognitive representations of concepts (Shapiro, 2011). We examined whether this holds also true for abstract concepts that cannot be directly perceived with the sensorimotor system (i.e., temporal concepts). To test this, participants learned object – space (Exp. 1) or object – time (Exp. 2) associations. Afterwards, participants were asked to assign the objects to their location in space/time meanwhile they walked backward, forward, or stood on a treadmill. We hypothesized that walking backward should facilitate the on-line processing of ”behind”- and “past”-related stimuli, but hinder the processing of “ahead”- and “future”-related stimuli, and a reversed effect for forward walking. Indeed, “ahead”- and “future”-related stimuli were processed slower during backward walking. During forward walking and in the control condition, all stimuli were processed equally fast. The results provide partial evidence for the activation of specific spatial and temporal concepts by means of whole-body movements and are discussed in the context of movement familiarity.

... This study explores the relationship between gender identity and the use of creaky voice (a non-modal phonation commonly referred to as "vocal fry.") While early research suggested that men were more likely to use creaky voice, more recently its use has been associated with the language use of young, urban, American women. This study explores the relationship between creaky voice and gender identity in American English, and investigates the social stratification of creaky voice for additional social factors like sexual orientation, age, and socioeconomic status. Production and perception data were gathered from 69 participants with a range of gender identities (including men, women, and non-binary individuals, as well as individuals who identify as both cis and trans) in 2013. The dataset contains audio files and tabular data.

... As a partner in Global Fund Round 7, PSI Angola is responsible for launching a nation-wide behavior change communication campaign to increase the use of insecticide treated mosquito nets among preg-nant women and children under five. PSI Angola will develop and launch a radio campaign directed at caregivers of children under the age of five. The present qualitative study is proposed to gain a greater understanding of the determinants of LLIN use from the user perspective in order to aid in the creation of focused, relevant and effective messages for the radio campaign.

... Many political science research articles that use limited dependent variable models report estimated quantities, in particular, fitted probabilities, predicted probabilities, and functions of such probabilities, without indicating that such estimates are subject to uncertainty. This practice, along with the reporting of "percentage correctly predicted," can overstate the precision of reported results. In light of this, the present article describes a variety of measures of uncertainty that authors can include alongside estimates generated by limited dependent variable models. It also proposes an alternative to "percentage correctly predicted" and illustrates its calculations with congressional cosponsorship data from Krehbiel (1995).
