“Global warming” versus “climate change”: A replication on the association between political self-identification,question wording,and environmental beliefs

Climate change is one of the greatest threats to humanity and requires immediate action. Schuldt, Konrath, and Schwarz (2011) suggested that beliefs in environmental phenomena can be influenced by the terminology used to describe it: changing question wording from global warming to climate change resulted in a 6.3 percentage point increase in belief in environmental phenomena. This association was moderated by political self-identification, with Republicans being 16.2 percentage points more likely to believe in climate change than in global warming, with Democrats showing no difference. The potential for connotative meanings to shift over time and the sociopolitical changes since the original study, potential policy and environmental campaign implications, and an expansion of these findings to other countries, motivated an attempt to replicate this important finding. This pre-registered study repeated the original procedures in the United States of America and two other countries (United Kingdom and Australia; total N = 5,717). Although question wording no longer had a significant effect on beliefs in climate change/global warming, the association of political self-identification with beliefs in environmental phenomena replicated in all three countries, with Conservatives consistently believing less in climate change/global warming than Liberals. The potential impacts of temporal and methodological differences on the discrepancies between this study's and the original's findings are discussed.     

‘Any place could be home’: Embedding refugees’ voices into displacement resolution and state refugee policy

This article explores refugees’ views about the ‘durable solutions’ or three Rs – Voluntary Repatriation, Local or Re-Integration and Resettlement – underscoring the need for refugees’ voices to inform policy actions taken on their behalf. Central to discourses on the right to return and the policy practice of voluntary repatriation is the salience accorded the nation-state of which territorial boundaries are an important defining feature. Drawing on ethnographic interviews with Liberian refugees in the Gomoa-Buduburam camp in Ghana, this article elucidates the effects of essentialist assumptions about territory, nation-state, home and enforced repatriation on the rights of refugees. By studying practices around and responses to the so-called solutions to displacement, especially VR, insights are gained into various ways in which space is reproduced and contested by international/local implementers and refugees, respectively, in the search for solutions. Importantly, the extent to which the views of displaced persons are allowed to shape such practices is highlighted. The article concludes by encouraging an embedding of refugees’ views about the three Rs into reformulating state policy expressions in displacement interventions. Including refugees as active participants in resolving their own problems, it is suggested, is one sustainable way to address the canker of protracted displacement in our times.     

Physicochemical study of the hubnerite-ferberite (MnWO4-FeWO4) zonal distribution in wolframite (Mn X Fe(1−X)WO4) deposits

A thermochemical approach to the problem of zonal structure in metallogenetics involving the use of Ellingham diagrams and minimization of free energy (ΔG) agrees closely with the “normal” zonal structure as defined by Fersman (1934). This approach is applied to the hubnerite-ferberite (MnWO₄-FeWO₄) solid solution in order to elucidate the repartition law of the Mn/Fe ratio in wolframite (Mn _X Fe_(1?X)WO₄). The study requires experimental determination of thermodynamical data, such as enthalpy ΔH of the solid solution, which is obtained using a high-temperature calorimetric method developed for this purpose. The calculation leads to an equation which gives the Mn molar value of wolframite with respect to temperature and the Mn/Fe ratio of the mineralizing solution. It is theoretically demonstrated that a high manganese content in wolframite is connected with high deposition temperature, but the decrease of the Mn/Fe ratio is a consequence of the decrease of the Mn/Fe ratio in the mineralizing solution, as can be observed in the Borralha deposit from which the geochemical study has been made. Conversely, a rapid lowering of the temperature of deposition leads to an increase of the Mn/Fe ratio in wolframite. Consequently, this ratio cannot be used as a geologic thermometer, but rather as an indicator of the position of the source of the mineralization.     

Tropospheric disturbance of 17–21 December 1974 and its effect on microwave propagation

A number of troposphere-monitoring experiments were pressed into service during a large tropospheric disturbance which lasted for several days in December 1974. The experiments operated intensively included a monostatic Sodar system, a satellite radio beacon receiver at very low elevation angles, Meteorological Radiosondes, a 250-kW weather radar, a microwave LOS link and a microbarograph. This multi-pronged campaign yielded very useful results and the correspondences between various observations were striking. The Sodar and microwave link observations were visibly affected only when N reached a value of about –70 units; however, the satellite beacon observations showed anomalous behaviour even for lower N values. Rather spectacular coincidences occurred on one night: the large fading (up to 10 db) in the LOS link; highly disturbed conditions displayed in the entire Sodar range; the largest tropospheric effect on the satellite beacon system; and the most active superrefraction of the radar echoes. It was also noticed that these effects are obvious only during nights, while they remain masked or dampened in the sun-lit hours.     

Beziehungen der ansteckenden Krankheiten zur Witterung mit besonderer Berücksichtigung derHeine-Medinschen Epidemien in Ungarn in den Jahren 1931–1947

Zusammenfassung Einleitend werden verschiedene ungarische Arbeiten über den Zusammenhang zwischen Witterung und Krankheiten kritisch besprochen. Nach einer Übersicht über die verschiedenen Ansichten über die Abhängigkeit der Poliomyelitis von der Witterung wird eine 17jährige Statistik aus Ungarn über Witterungseinflüsse auf diese Krankheit untersucht. Es konnte kein Zusammenhang mit der Temperatur, mit dem Wechsel des Witterungscharakters und mit Fronten oder Abgleitflächen nachgewiesen werden. In den an Poliomyelitisfällen reichsten Jahren waren trockene Monate etwas häufiger. Es zeigen sich schwache Anzeichen für eine Doppelwelle während einer Sonnenfleckenperiode. Die Krankheit trat in den kühleren und niederschlagsreicheren nördlichen und nordöstlichen Teilen des Landes am häufigsten auf.

Summary At first divers Hungarian papers on the relations between weather and diseases are critically discussed. After giving a survey of the different opinions as to the influence of weather upon poliomyelitis, a 17 years statistics from Hungary is investigated in this respect. No connection could be found, however, neither with the temperature and the change of weather character nor with fronts or surfaces of subsidence. Most poliomyelitis cases occurred in years in which dry months were a little more frequent. There are slight indications of a double wave during a sunspot period. The disease was found to be most frequent in the northern and north-eastern regions being relatively cooler and richer in precipitation.

Résumé On examine tout d'abord différentes études hongroises concernant les relations entre le temps météorologique et les maladies. Après un aperçu sur les diverses opinions émises au sujet de la poliomyélite et de sa dépendance à l'égard du temps, on étudie sur le même sujet une statistique de 17 ans établie en Hongrie. On n'a pas pu prouver de relation avec la température, avec les changements de temps, ni avec les fronts ou les surfaces de subsidence. Les années les plus riches en poliomyélite ont eu un peu plus de mois secs. De faibles indices parlent en faveur d'une double période à l'intérieur de la période des taches solaires. La maladie a été la plus fréquente dans les parties nord et nord-est du pays qui sont aussi les plus froides et les plus humides.

     

Seismic sequence stratigraphy of Miocene deposits related to eustatic,tectonic and climatic events,Cap Bon Peninsula,northeastern Tunisia

The Cap Bon Peninsula, belonging to northeastern Tunisia, is located in the Maghrebian Alpine foreland and in the North of the Pelagian block. By its paleoposition, during the Cenozoic, in the edge of the southern Tethyan margin, this peninsula constitutes a geological entity that fossilized the eustatic, tectonic and climatic interactions. Surface and subsurface study carried out in the Cap Bon onshore area and surrounding offshore of Hammamet interests the Miocene deposits from the Langhian-to-Messinian interval time. Related to the basin and the platform positions, sequence and seismic stratigraphy studies have been conducted to identify seven third-order seismic sequences in subsurface (SM1-SM7), six depositional sequences on the Zinnia-1 petroleum well (SDM1-SDM6), and five depositional sequences on the El Oudiane section of the Jebel Abderrahmane (SDM1–SDM5). Each sequence shows a succession of high-frequency systems tract and parasequences. These sequences are separated by remarkable sequence boundaries and maximum flooding surfaces (SB and MFS) that have been correlated to the eustatic cycles and supercycles of the Global Sea Level Chart of Haq et al. (1987). The sequences have been also correlated with Sequence Chronostratigraphic Chart of Hardenbol et al. (1998), related to European basins, allows us to arise some major differences in number and in size. The major discontinuities, which limit the sequences resulted from the interplay between tectonic and climatic phenomena. It thus appears very judicious to bring back these chronological surfaces to eustatic and/or local tectonic activity and global eustatic and climatic controls.     

Coupes équilibrées à travers le massif subalpin de la Chartreuse

Résumé

Pour étudier la tectonique des chaînes subalpines du Nord, et proposer un modèle cinématique régional, nous avons utilisé les résultats d’une expérience géophysique réalisée en 1985, et les observations géologiques de surface publiées à ce jour. Ces données ont été analysées de manière à préciser le style tectonique, le positionnement des failles par rapport aux horizons stratigraphiques et le schéma de branchement des failles. La construction simultanée d’une coupe interprétative, d’une coupe restaurée et d’une carte de branchement des failles a permis d’estimer l’amplitude du raccourcissement par la méthode des coupes équilibrées. Au niveau du Nord de la Chartreuse, la valeur minimale du raccourcissement global est de 14 km, 4 km étant associés au système chevauchant du Jura et 10 km à celui du massif des Bornes et des Bauges. Compte tenu des imprécisions existant sur les données utilisées, trois modèles cinématiques, qui correspondent à une plage de raccourcissement comprise entre 14 et 25 km, sont proposés.     

New age constraints on emplacement of the Cévenol granitoids, South French Massif Central

During the development of the Variscan orogeny, large amounts of granitic melt were produced, giving rise to the intrusion of granitoids at different structural levels. Despite numerous studies, ages available from previous work on the Cévennes granites remain largely imprecise. In order to better constrain the age and emplacement mode of these granites, we have combined U–Pb dating on monazites and zircons and ⁴⁰Ar/³⁹Ar dating on biotites with petrological observations, major element chemical analysis and SEM zircon imaging on five samples from the Aigoual–St Guiral–Liron and Mont Lozère granitic massifs. The results revealed that granitic intrusions and cooling in Southern Cévennes occurred in a short time span at ∼306 Ma after the main episode of regional metamorphism. Petrological and chemical data suggest that they result from a mixing between mantle-derived basic magmas (lamprophyres) and lower crust acid magmas. At a regional scale the production of these melts occurred at the end of crustal thickening induced by nappe stacking, at the same time as the late anatectic events recorded further north in the Velay dome and the granulite facies metamorphism recorded in metasedimentary granulite enclaves brought up by Tertiary volcanoes of the Velay area (Bournac).     

Dynamics of magma mixing and degassing recorded in plagioclase at Stromboli (Aeolian Archipelago,Italy)

Crystal-rich materials (scoriae and lava flows) emitted during the 1985–2000 activity of Stromboli were taken into consideration for systematic study of bulk rock/matrix glass chemistry and in particular for the study of chemical and textural zoning of plagioclase, the most abundant mineral phase. Over the considered time period, bulk rock composition remained fairly constant in both major (SiO₂ 49.2–50.9 wt% and K₂O 1.96–2.18 wt%) and trace elements. The quite constant chemistry of matrix glasses also indicates that the degree of crystallization of magma was maintained at around 50 vol%. Plagioclase ranges in composition between An₆₂ and An₈₈ and is characterized by alternating, <10–100 m thick, bytownitic and labradoritic concentric layers, although the dominant and representative plagioclase of scoriae is An_68. The labradoritic layers (An_62–70) show small-scale (1–5 µm), oscillatory zoning, are free of inclusions, and appear to record episodes of slow crystal growth in equilibrium with a degassed liquid having the composition of the matrix glass. In contrast the bytownitic layers (An₇₀-An₈₈) are patchy zoned, show sieve structure with abundant micrometric glass inclusions and voids, and are attributed to rapid crystal growth.A key to understanding the origin of bytownitic layers can be retrieved from the texture and composition of the coronas of plagioclase xenocrysts, inherited from crystal-rich magma, in nearly aphyric pumice which are erupted during more energetic events and represent a deep, volatile-rich, HK-basaltic magma. They show a continuum from fine-sieve to evident skeletal texture from the inner to the outer part of the corona associated with normal compositional zoning from An₉₀ to An₇₅. In the light of these observations, we propose that input of H₂O-rich melt blobs, and their mixing with the residing magma, causes partial dissolution of the labradoritic layers followed by the growth of bytownitic composition whose sieve texture attests of rapid crystallization occurring under undercooling conditions mainly induced by degassing. As a whole, the zoning of plagioclase in the scoriae records successive and discrete intrusions of volatile-rich magma blobs, its degassing and mixing with the resident degassed magma at shallow level.Editorial responsibility: T.L.
