The ecology of the slow-worm (Anguis Fragilis L.) in Southern England
The slow-worm, Anguis fraqilis, is a legless lizard in the family Anguidae. The ecology of the species was studied by weekly visits to two sites on the Isle of Purbeck, Dorset, England from 1981 to 1988. Other sites were visited less often. Animals were found under pieces of corrugated iron sheet that had been placed on the ground. Adults were photographed and identified on recapture by the pattern on the underside of the head. Pregnant females were retained in captivity until the birth of the young.A total of 3456 slow-worms were found. Capture rates of known individuals were low, often less than once a year. There were differences in rate of captures of four sex and size class over the season. Males predominated in spring, females were found most often in summer and sub-adults and juveniles were commonest in autumn. Rates of movement were low. There was no evidence of territory formation.Mating was only observed once. Females with sperm in the cloaca were found in May. The litters of 1 to 18 (average 8) were born in late summer. Larger females had larger litters but not larger young. In 1986, litter sizes were small with many of the young deformed. The sex ratios were not equal. The bias was to females at one site and to males at the other.Cloacal temperatures, low for a temperate reptile, ranged from 9.8 to 33.2 "C, with a median of 24.9 °C. There was little evidence of precise thermoregulation. Cloacal temperatures were highest in summer on sunny days, but varied little with time of day. The distribution in the Iberian peninsula was shown by discriminant function analysis to be correlated with cooler, wetter climates.<br/
Theory and Imagination in Comparative Politics: An Interview with Lisa Wedeen
In an interview with Lisa Wedeen, one of the contemporary comparative political scientists whose work most consistently speaks to both political science and interdisciplinary audiences, the editors ask Wedeen to reflect on the role that comparison has played in her work. Wedeen is the author of three groundbreaking monographs on seemingly single cases – two on Syria and one on Yemen. Yet, in the course of the interview, it becomes apparent how profoundly comparative Wedeen’s work is. She discusses her comparison of “exemplary events” in her field sites as a method through which to draw broad lessons about politics from apparent ephemera. She discusses the comparisons she makes between ethnographic insights and political theory to tack back and forth between empirical and theoretical material with the goal of developing new ways to think about politics. And she discusses the ways in which these comparative practices make her work not just an empirical practice but also a political practice – one that makes the work of a comparative political scientist not just a career but a vocation

Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Rethinking Comparison: An Introduction
Comparison is a key tool in the social sciences. Scholars make comparisons across time and place to better understand our social and political worlds. A central technique that scholars use is often called ‘controlled comparison.’ Controlled comparisons rely on scholars holding possible explanations for the outcome of interest (e.g., revolutions or political participation) constant across different cases. This approach has been central to some of the most influential works of social science. It has helped scholars explain everything from divergent development outcomes to difference in regime type. Yet controlled comparisons are not the only form of comparison that scholars utilize to answer important questions. There is little guidance, however, for how to design or execute these comparisons or why research that does not rely on controlled comparisons can offer important insights. The goal of this edited volume is to begin to develop some of these guidelines. To do so, this volume explores two of the most fundamental questions in the study of politics: (1) why do scholars compare what they compare and (2) how do the methodological assumptions scholars make about why and how they compare shape the knowledge they produce? By answering these questions, the volume creates new resources for future students and researchers to draw upon in their efforts to advance knowledge
