  abstract  = {This article investigates the fictional narratives written by „Sub-commandante Marcos" of the Zapatista movement EZLN. It is shown that Marcos uses three distinct frames of reference in his fictional account of the Zapatista guerrilla: an ethnic, a national and a post-national one. Contrary to other studies that emphasize the harmony between the three levels, it can be argued that there exists a fundamental tension between them. There is a tension between the ethnic discourse and the Mexican nationalist discourse which envisions a nation rather than a nation dominated by a single ethno-cultural group. Finally, it can be deduced from these tensions that the EZLN guerrilla is subject to divergent pressures.},

  abstract  = {Isabel Lake is a hypersaline crater-lake on Isabel Island, Mexico, situated in the eastern tropical Pacific, an area highly sensitive to hydrological changes. Today, annual rainfall mostly occurs during the wet season, from June to October, when the northern edge of the Intertropical Convergence Zone (ITCZ) extends over the island. In order to evaluate the potential of sedimentary lipid biomarker signatures as a proxy of past hydro-climatic variability we have performed a calibration analysis comparing changes in biomarker distribution in the upper 16 cm of the sediment core with a regional instrumental data set. Annual laminations present in the sediment sequence allow for precise chronological control (1942-2006), More than 80 different lipid compounds were identified in the sediment and could be assigned to three major groups of source organisms: (1) algal populations; (2) a mixed community of ciliates, bacteria and cyanobacteria; and (3) photosynthetic sulfur bacteria. We found that the observed changes in the. relative contribution of the different lipid biomarkers to the sediment record were determined by the regional rainfall variability over the last 65 years. The planktonic community of Isabel Lake was highly sensitive to salinity fluctuations related to rainfall variability; seasonal precipitation results in freshwater input into the lake, driving an annual algal bloom and a relative decrease in the abundance of the more halotolerant populations of (cyano) bacteria and ciliates. Consequently, the concentration ratio between the two most abundant biomarkers in the Isabel Lake sediments, n-alkyl diols and tetrahymanol (which we define as the DiTe index), representing algal and ciliate planktonic populations, respectively, was significantly correlated with the seasonal rainfall anomaly (r = 0.68, p < 0.01). We propose that the DiTe index is a proxy of changes in the aquatic ecosystem of Isabel Lake and, by extension, regional hydrological changes in a sensitive climatic area of the eastern tropical Pacific.},

Der Autor analysiert das Verh{\"a}ltnis zwischen Arbeitern aus Mexiko und der US-amerikanischen Arbeiterbewegung, insbesondere den Gewerkschaften. Er tut dies an zwei Fallbeispielen, in denen Gewerkschaften versuchten bzw. versuchen, in Kalifornien transnationale Arbeiter zu organisieren: Zum einen wird das Los Angeles Manufacturing Project (LAMAP) betrachtet, zum anderen der immer noch andauernde Arbeitskampf in der Mandelfabrik Blue Diamond Growers (BDG) in Sacramento/Kalifornien. Abschließend wird die Frage beantwortet, ob die traditionellen Gewerkschaften der USA f{\"u}r die Interessenvertretung und Integration von Menschen mit Migrationshintergrund im Niedriglohnsektor geeignet sind. Christian Kube ist der Ansicht, dass sie einen wesentlichen Beitrag zur Organisation transnationaler Arbeiter leisten m{\"u}ssen, da es derzeit keine ann{\"a}hernd so mitgliederstarken Institutionen wie die Gewerkschaften in den USA gibt.},

  abstract  = {During his trip to New Spain in 1803, Alexander von Humboldt visited large tracts of New Spanish territory, which includes modern Mexico and part of the United States. This trip provided the data for his geographical Atlas of the region, as well as information about the ancient Mexican cultures that he would later include in the general Atlas and in other major works, such as Vues des Cordill{\`e}res. Likewise, Humboldt's Political Essay on the Kingdom of New Spain displayed a comprehensive physical, natural, economic, and social description of Mexico in the colonial period, which will also be analysed. With these works, Humboldt presented a new geographical and cultural image of New Spain to the European audiences. In addition to this, his work made important contributions to cartographic knowledge.},

  abstract  = {We present varve chronologies for sediments from two maar lakes in the Valle de Santiago region (Central Mexico): Hoya La Alberca (AD 1852-1973) and Hoya Rincn de Parangueo (AD 1839-1943). These are the first varve chronologies for Mexican lakes. The varved sections were anchored with tephras from Colima (1913) and Paricutin (1943/1944) and (210)Pb ages. We compare the sequences using the thickness of seasonal laminae and element counts (Al, Si, S, Cl, K, Ti, Mn, Fe, and Sr) determined by micro X-ray fluorescence spectrometry. The formation of the varve sublaminae is attributed to the strongly seasonal climate regime. Limited rainfall and high evaporation rates in winter and spring induce precipitation of carbonates (high Ca, Sr) enriched in (13)C and (18)O, whereas rainfall in summer increases organic and clastic input (plagioclase, quartz) with high counts of lithogenic elements (K, Al, Ti, and Si). Eolian input of Ti occurs also in the dry season. Moving correlations (5-yr windows) of the Ca and Ti counts show similar development in both sequences until the 1930s. Positive correlations indicate mixing of allochthonous Ti and autochthonous Ca, while negative correlations indicate their separation in sublaminae. Negative excursions in the correlations correspond with historic and reconstructed droughts, El Nio events, and positive SST anomalies. Based on our data, droughts (3-7 year duration) were severe and centred around the following years: the early 1850s, 1865, 1880, 1895, 1905, 1915 and the late 1920s with continuation into the 1930s. The latter dry period brought both lake systems into a critical state making them susceptible to further drying. Groundwater overexploitation due to the expansion of irrigation agriculture in the region after 1940 induced the transition from calcite to aragonite precipitation in Alberca and halite infiltration in Rincn. The proxy data indicate a faster response to increased evaporation for Rincn, the lake with the larger maar dimensions, solar radiation receipt and higher conductivity, whereas the smaller, steeper Alberca maar responded rapidly to increased precipitation.},
