Govender, R., Bisconti, M. & Chinsamy, A., June 2016. A late Miocene–early Pliocene baleen whale assemblage from Langebaanweg, west coast of South Africa (Mammalia, Cetacea, Mysticeti). Alcheringa 40, xxx–xxx. ISSN 0311-5518

Knowledge of post-Eocene cetaceans from Africa is very poor with almost nothing known about this group from southern Africa except for the diverse trawled ziphiids. Langebaanweg, a locality yielding prolific Miocene–Pliocene fossils on the southwestern Cape coast of South Africa, preserves terrestrial and marine biotas in juxtaposition. Palaeoenvironments vary from a marine shoreline to a lagoon and estuary and later a shallow marine environment and include several microhabitats. Fragmentary preservation of the cetacean skeletons suggests that they were transported before burial. This first detailed analysis of the Mio-Pliocene mysticete fossils from Langebaanweg uses the petrotympanic region to taxonomically identify specimens. Three un-named species of balaenopterid Mysticeti represent a Plesiobalaenoptera-like form, but it is premature to erect a new taxon based on this fragmentary material. The remaining material is too poorly preserved to be identified with confidence.

The literature finds evidence that the presence of strong institutional veto players correlates with policy gridlocks. In recent years, in several European countries the rationale of parliamentary second chambers as veto players has been called into question. With regard to Italy, in 2016 the parliament approved a broad constitutional reform, later rejected by a referendum. According to the proponents, this reform would have made Italian institutions more functional in a comparative perspective. Did voters actually block some sort of functionality? To answer this question, this article presents a systematic comparison of second chambers in the European Union. The theoretical framework is based on three dimensions of strength, operationalized by means of quantitative indicators and a comprehensive index of strength. The article ends with a discussion of the findings and a proposal for further research outlooks.  相似文献

Studies on party institutionalisation commonly argue that parties with personalist leadership and weak organisation are unlikely to remain in power beyond leadership succession. In other words, these parties will rarely attain their own institutionalisation. From this perspective, the recent Italian political reality represents a conundrum. Three parties of this type – Northern League; Forza Italia; Italy of Values – confronted significant resignation issues concerning their leaders, but only the League, contrary to the theory, made a decisive step toward institutionalisation by removing its founding father and remaining an actor with national blackmail potential. This article addresses this challenge and provides a solution to this conundrum. In particular, the article demonstrates that an approach that considers both party factors and critical events is necessary to account fully for the variance of outcomes and, more generally, for party change.  相似文献
