Climatic and cave settings influence on drip water fluorescent organic matter with implications for fluorescent laminations in stalagmites
Speleothem fluorescence can provide insights into past vegetation dynamics and stalagmite chronology. However, its origin and especially the formation of fluorescent laminations in stalagmites are poorly understood. We conducted a year-long monthly monitoring of drip water fluorescence in La Vallina Cave (northern Iberian Peninsula) and compared the results to drip water chemistry and active speleothems from the same sites. Drip waters were analy…
Exploring a Mallorca cave flooding during the Little Ice Age using nondestructive techniques on a stalagmite
This study focuses on characterizing a discontinuity within the Seán stalagmite (4.75–7.75 cm) by means of two nondestructive techniques: (1) high-resolution micro-computed tomography (micro-CT) and (2) X-ray fluorescence (XRF) core scanning (XRFCS). Micro-CT was used to study the stalagmite density, and XRFCS was applied to obtain the qualitative elemental composition and colour measurements. The new data obtained from nondestructive techniques …
Social Diversity, Electoral Systems, and the Party System
Scholars commonly argue that in democratic societies, the size (or fragmentation) of party systems is a linear function of social heterogeneity, in interaction with political institutions such as the electoral system. This “interactive hypothesis” has generated a large body of research, mostly in support of its fundamental claims. Despite the prominence of this literature, there is also a growing body of research that casts doubt on the interacti…
New speleothem data from Molinos and Ejulve caves reveal Holocene hydrological variability in northeast Iberia
New speleothem records from northeastern Iberian caves provide data to explore the climatic patterns during the Holocene. We present δ 13 C and Mg/Ca from three speleothems from two different caves located in the Iberian Range allowing replication of the climatic signal for several millennia. Through the integration of those stalagmites covering since the Holocene onset to 2 ka, the early Holocene (11.7–8.5 ka) appears as the wettest interval. A …
Legislative policy-making authority, party system size, and party system nationalization
Presidential coattails
This article takes a closer look at how presidential elections affect the fragmentation of the legislative party system. It reviews the theory and conventional empirical modelling strategy; identifies some drawbacks to this strategy and suggests solutions; and then conducts an empirical investigation of the implications of this critique by combining replication data from Golder (2006) with new data on the key variables measuring the presidential …
Paleoclimate and growth rates of speleothems in the northwestern Iberian Peninsula over the last two glacial cycles
Speleothem growth requires humid climates sufficiently warm to stimulate soil CO 2 production by plants. We compile 283 U/Th dates on 21 stalagmites from six cave systems in the NW coast of Spain to evaluate if there are patterns in stalagmite growth that are evidence of climatic forcing. In the oldest stalagmites, from marine oxygen isotope stage (MIS) 7–5, growth persists through the glacial period. Hiatuses and major reductions in growth rate …
Isotope and trace element evolution of the naica aquifer (Chihuahua, Mexico) over the past 60,000 yr revealed by speleothems
The “espada” speleothems of Cueva de las Espadas (Naica Mine, Chihuahua, Mexico) comprise a high-purity selenite core overlain by successive deposits of calcite, gypsum and aragonite. Gypsum precipitated under water from a hydrothermal solution (~ 58°C) when the water table was above the cave level ca. 57 ka, during the last glaciation, and some intervals during deglaciation and the Holocene. Aragonite was deposited at lower temperatures (~ 26°C)…
Age and significance of the Quaternary cemented deposits of the Duje Valley (Picos de Europa, Northern Spain)
Cemented calcareous breccias appear in the Picos de Europa (Cantabrian Mountains, Spain) resting on glacially abraded surfaces and covered by moraines. U/Th dating of the calcite coating the clasts was successful in two samples, the oldest one indicating that the breccias accumulated during or prior to Marine Isotope Stage (MIS) 11, and the youngest indicating later cementation during MIS 8. The former introduces a limit for the age of the glacia…
Are All Presidents Created Equal? Presidential Powers and the Shadow of Presidential Elections
Presidential elections with few candidates held in temporal proximity to legislative elections are believed to promote the nationalization and consolidation of the legislative party system. However, contrary to the existing literature, the authors argue here that the shadow presidential elections cast over legislative elections is contingent on the relative powers of the president vis-à-vis the legislature. Specifically, the authors find that pro…
Dimensionality and the number of parties in legislative elections
This article explores how the party-defined dimensionality of political competition relates to the number of parties competing in legislative elections. It demonstrates that a mathematical relationship between the number of electoral parties and the literature’s concept of dimensionality follows from the variables’ definitions; conversely, it argues that exploring the relationship between the number of electoral parties and a different concept of…
Presidents and Parties
This article explicates the mechanisms through which presidential elections shape the legislative party system, an issue that has received little attention to date. The authors argue that presidential elections exert their influence through two distinct channels. First, they affect the incentives of candidates, voters, and parties to coordinate within electoral districts. Second and most importantly, they shape the incentives of candidates to coo…
Elite-Level Conflict Salience and Dimensionality in Western Europe
This paper uses the Comparative Manifestos Project to explore both the changing salience of different issues on the party-defined political agenda and their structuration in Western Europe from the 1950s through the early 2000s. These measures of the political space, the most extensive time series measures constructed to date, allow the paper to weigh in on elite-level claims of the de-alignment thesis, a complement to analyses operating at the m…
What Moves Parties
Do Western European political parties adjust their ideological positions in response to shifts in public opinion and to changing global economic conditions? Based on a time-series, cross-sectional analysis of parties' ideological dynamics in eight Western European democracies from 1976-1998, the authors conclude that both factors influence parties' ideological positions but that this relationship is mediated by the type of party. Specifically, th…
Electoral Rules and the Size of the Prize
This paper explores how political institutions besides electoral rules shape the presidential party system. Our focus is upon what we call the “size of the presidential prize”: the degree to which authority is concentrated in the presidency vis-à-vis the legislature (horizontal centralization) as well as in the national level of government vis-à-vis the subnational levels (vertical centralization). We find a significant but nonlinear relationship…
Social Cleavages and the Number of Parties
This article explores the issues surrounding the operationalization and measurement of social cleavages in a large- N context from the perspective of the party systems literature. It first highlights the difficulty of measuring the concept, which it argues has impeded hypothesis testing, and suggests strategies for improving upon existing measures. It then demonstrates that the conclusions we draw about well-known hypotheses linking social cleava…
