In this portrait, Irene Liefshitz considers learning as an aspect of teaching—how teachers learn to teach, what they learn about teaching, and how they are transformed by teaching. Because unsolicited, free-ranging, teacher-to-teacher conversation about teaching rarely makes it to education research, the author analyzes conversations between teachers recorded for the StoryCorps National Teachers Initiative to inquire how teachers talk about learning and what they say about it when no researcher is guiding their conversation. Such centering of teacher voice is a practical and political stance and positions education research as an act of listening. By transmitting and interpreting teachers’ talk, the author makes a case for focusing research agendas on teacher learning based on what teachers say is important to them, for promoting a scholarship of voice in research on teaching, and for further use of the StoryCorps National Teachers Initiative as a rich data source of teacher voice.

Historians of economics have paid minimal attention to the diffusion of economic ideas in the textbook literature. Given the low esteem in which textbooks are held as embodiments of scholarship and the propensity of historians of economics - and intellectual historians generally - to focus on the production of scholarship through more lofty venues such as journal articles and scholarly books, this lack of attention to the textbook literature is in some ways understandable. This article argues that the textbook literature constitutes an incredibly rich data source for the historian of economics. In doing so, it offers illustrations from the treatment of the Coase theorem in the textbooks, with a view both to showing how the textbook literature enhances our understanding of the diffusion of economic ideas and how attempts by authors to grapple with new ideas in the context of the textbook literature can result in divergences between how these ideas are treated in the scholarly and textbook literatures.

This study investigates the car-following behavior during braking at intersections and segments. Car-following events were extracted from a naturalistic driving dataset, mapped using ArcGIS, and analyzed to differentiate between the intersection- and segment-related events. The intersection-related events were identified according to an intersection influence area, which was estimated based on the stopping sight distance and the speed limit. Five behavioral measures were quantified based on exploring the probability density functions (PDF) for intersection- and segment-related events. The results showed that there were significant differences between the PDFs of the measures for both cases. Moreover, it was indicated that drivers tend to be more aggressive at intersections compared with segments. Thus, it is crucial to consider the driver’s location when investigating driver behavior. The quantified behavioral measures are a rich data source that can be used for car-following microscopic modeling, surrogate safety analysis, and driver assistance systems development.

From a typological perspective, the verbs of sitting, standing and lying have been described relatively extensively. Against this background, the present paper provides a contrastive study of the lexical semantics of the Swedish posture verbs sitta ‘sit’, stå ‘stand’ and ligga ‘lie’ based on the Multilingual Parallel Corpus (MPC), which contains extracts from Swedish novels and their published translations into English, German, French and Finnish. Since the corpus is a very rich data source, the study is focused on the use of posture verbs as locative verbs. It turns out that it is possible to arrange the languages along a continuum with respect to the use of posture verbs versus the copula to describe the location of inanimate objects. In Finnish the copula dominates completely, in English there is more of a balance (in this kind of written text), whereas the posture verbs dominate in German and Swedish. French stands out as a completely different type in this comparison, since the copula is used very little and posture verbs hardly at all. Actually, there is a tension in French between the use of a small number of verbs with a general locative meaning as translations and the use of a large variety of reflexive verbs and resultative constructions with past participles (e.g. être fixé ‘be attached’) which convey fine-grained information about the placement. Among the languages that use posture verbs as locative predicates, there is a general similarity with respect to the factors that condition the choice between lie and stand, whereas even closely related Germanic languages differ with respect to the semantic factors that condition the choice of sit as a locative predicate.

Resource Effect

What explains which groups are included in a party coalition in any given election cycle? Recent advances in political party theory suggest that policy demanders comprise parties, and that the composition of a party coalition varies from election to election. We theorize three conditions under which parties articulate an interest group’s preferred positions in its quadrennial platform: when groups are ideologically proximate to the party median, when groups display party loyalty, and when groups are flush with resources. Using computer-assisted content analysis on a unique and rich data source, we examine three cycles of testimony that 80 organized groups provided to the Democratic Party. The analysis compares group requests with the content of Democratic and Republican National Committee platforms in 1996, 2000, and 2004. Results show that parties reward loyal groups and those that are ideologically proximate to the party but offer no confirmation of a resource effect.

IntroductionManitoba Public Health Nurses (PHNs) attempt to visit all families with newborns shortly after discharge from birth hospitalizations. Since 2000, PHNs have completed the Families First Screen (FFS) at these visits, to identify families at risk for child maltreatment. The information captured in FFS is a valuable tool for research. Objectives and ApproachOur objective was to clean and validate FFS data and link to health data in the Manitoba repository in order to determine the percent of births in Manitoba hospitals that had FFS. We identified all babies born in Manitoba hospitals 2000-2015 using ICD-9-CM /ICD-10-CA codes. Mothers were identified through the Health Registry (Mom_Baby Link File) using scrambled Personal Health Identification Numbers (sPHINs). FFS data were linked to births via baby’s sPHIN. Determining which FFS records linked to babies required several steps of cleaning and validating the data to account for differences in birthdates between files, missing sPHINs, and multiple records. ResultsFor example, in 2014 there were 16,079 births and 14,002 FFS records; 13,524 FFS had mother and/or baby sPHIN. For those missing baby sPHIN (9,295), 99.8% were retrieved via the Mom_Baby Link File. Linking the FFS to the hospital births we found: 3,043 births didn’t have an FFS; 12,762 had a single FFS, and 274 births had multiple FFS (i.e., baby associated with more than one mother, FFS and/or form date). To ensure that the baby was only associated with one mother and one FFS the most current FFS was kept. We found that in 2014, 81.07% (13,036/16,079) of the births had an FFS. In the longitudinal analysis, the percent of births with an FFS ranged from 74.6% in 2000 to 81.1% in 2014. Conclusion/ImplicationsWe were able to achieve good linkage between FFS and health registry data, allowing this rich data source to be used for research on maternal and child health. Information on percent of births with FFS has been shared with policy-makers over the years and changes to screening practices implemented.

Over Time

The concept of life space refers to the different locations with which individuals interact along their life course. In this article we present several methodological proposals to describe and measure various territories to which individuals relate over time, taking advantage of a rich data source, the Biographies et entourage survey. We produce relevant indicators which can be used in the study of different demographic processes and demonstrate how this perspective elegantly formalizes the linked dynamics of interactive non-independent trajectories in the case of the couples’ activity space.

The Impact

Herbarium specimens can be used to reconstruct spatiotemporal changes in plant morphology caused by environmental pressures. The reliability of herbarium-derived data requires evaluation, because specimen collection is subject to biases. We used herbarium and field data to investigate the impact of large herbivore browsing on the size of a forb. White trillium (Trillium grandiflorum (Michaux) Salisbury) was studied because the impacts of white-tailed deer (Odocoileus virginianus Zimmermann) browsing on this species are well-known. A total of 692 herbarium specimens collected in Quebec (Canada) were used to evaluate leaf area. Leaf area values of herbarium specimens were compared with those of modern (2013, 2014) specimens collected in sites either with >8 deer per square kilometre or without deer. Flowering individuals in modern sites with deer had a significantly lower leaf area than herbarium specimens and modern specimens collected in sites without deer. The distribution of white trillium individuals in deer sites was also skewed towards plants with a smaller leaf area. Herbarium specimens may offer unique and inexpensive data, compared with methods traditionally used to assess the impacts of herbivores on plants, such as exclosures or clipping experiments. Unfortunately, this rich data source is seriously jeopardized by the downtrend in specimen collecting.
