This article examines the decision in May 1960 by the British colonial secretary, Iain Macleod, to accelerate dramatically the independence timetable for Tanganyika. Making extensive use of recently released archive material, it looks at the key factors behind this largely neglected but nevertheless significant episode, seeking to demonstrate that, despite Macleod's subsequent recollection of events, there was a clear policy change in May 1960; that it was for the main part external nationalist and internationalist pressures which led to the policy change; that, importantly, newly identified short-term factors of a change of heart by nationalist leader Julius Nyerere, events in Somaliland and the need to demonstrate positive Commonwealth credentials were the immediate and decisive reasons behind the acceleration; and that, in explaining the advancement, it is valuable to understand why and how individual factors contributed to the policy change and how they worked together.  相似文献

A new archostematan beetle, Clessidromma palmeri gen. et sp. nov. (Insecta: Coleoptera) is described from mid-Cretaceous Burmese amber from northern Myanmar. It has a uniquely specialized body form for which a new stem tribe, Clessidromatini trib. nov., is proposed in the subfamily Ommatinae of the family Cupedidae sensu lato.

Wang, Q., Wang, Y., Qi, Y., Wang, X., Choh, S.J., Lee, D.C. & Lee, D.J., November 2017. Yeongwol and the Carboniferous–Permian boundary in South Korea. Alcheringa 42, 245–258. ISSN 0311-5518

Six conodont and one fusuline zones are recognized on basis of a total of 25 conodont and 13 fusuline species (including seven unidentified species or species given with cf. or aff. in total) from the Bamchi Formation, Yeongwol, Korea. The conodont zones include the Streptognathodus bellus, S. isolatus, S. cristellaris, S. sigmoidalis, S. fusus and S. barskovi zones in ascending order, which can be correlated with the conodont zones spanning the uppermost Gzhelian to Asselian Age of the Permian globally. The fusuline zone is named the Rugosofusulina complicata–Pseudoschwagerina paraborealis zone. The co-occurrence of the conodont Streptognathodus isolatus (the Global Boundary Stratotype Section and Point index for the base of Permian) and Pseudoschwagerina (a Permian inflated fusuline) indicates that the Carboniferous–Permian boundary can be placed in the lower part of the Bamchi Formation in South Korea.

Invasive vegetation species can lead to major changes in the geomorphology of coastal systems. Within temperate estuaries in the southern hemisphere, especially Australia and New Zealand, the cordgrass Spartina spp. has become established. These species are highly invasive, and their prolific growth leads to the development of supratidal environments in formerly intertidal and subtidal environments. Here, we quantified the impact of Spartina invasion on the geomorphology and sequestration capacity of carbon in the sediments of Anderson Inlet, Victoria, Australia. Spartina was first introduced to the area in the 1930s to aid in land reclamation and control coastal erosion associated with coastal development. We found that Spartina now dominates the intertidal areas of the Inlet and promotes accretion (18 mm/year) causing the formation of over 108 ha of supratidal islands over the past 100 years. These newly formed islands are calculated to potentially contain over 5.5 million tonnes of CO2 equivalent carbon. Future management of the inlet and other Spartina‐dominated environments within Australian presents a dilemma for resource managers; on the one hand, Spartina is highly invasive and can outcompete native tidal marshes, thereby warranting its eradication, but on the other hand it is likely more resilient to rising sea levels and has the potential for carbon sequestration. Whether or not the potential advantages outweigh the significant habitat change that is anticipated, any management strategies will likely require additional research into costs and benefits of all ecosystem services provided by Spartina including in relation to nutrient cycling, shoreline stabilisation, and biodiversity as well as in response to the longevity of carbon found within the sediments.  相似文献

制度设置必须考虑成本与收益问题。以关于惩戒“包二奶”的讨论为例,“道德派”强调自由与隐私权,主张“把道德的东西还给道德”,“法律派”认为,道德无力时应用法律规范。以成本分析法看,自由与隐私权是社会性的,在家庭仍有社会成本与收益效应时,“包二奶”应得到惩戒,道德惩戒的成本低廉,但在陌生人社会作用有限,法律惩戒成本稍高,但收益可靠。  相似文献
