Testing multiple pathways for impacts of the non-native Black-headed Weaver Ploceus melanocephalus on native birds in Iberia in the early phase of invasion

Not all non-native species have strong negative impacts on native species. It is desirable to assess whether a non-native species will have a negative impact at an early stage in the invasion process, when management options such as eradication are still available. Although it may be difficult to detect early impacts of non-native species, it is necessary to ensure that management decisions can be based on case-specific scientific evidence. We assess the impacts of a non-native bird, the Black-headed Weaver Ploceus melanocephalus, at an early stage in its invasion of the Iberian Peninsula. To do this we identify potential pathways by which competition for shared resources by Black-headed Weavers could lead to population declines in two ecologically similar native species, and generate hypotheses to test for evidence of competition along these pathways. Black-headed Weavers could potentially impact native species by displacing them from nesting habitat, or by reducing habitat quality. We found no evidence for either potential competition pathway, suggesting that Black-headed Weavers do not currently compete with the two native species. However, it is possible that mechanisms that currently allow coexistence may not operate once Black-headed Weavers reach higher population densities or different habitats

Challenges towards renewable energy : an exploratory study from the Arabian Gulf region

Considering the importance of energy for social and economic development, access to clean, affordable and reliable energy has been adopted as one of the United Nations sustainable development goals that all countries aim to achieve by 2030. However, much of the world's energy is still produced from fossil fuels and thus the progress towards clean and renewable energy is slow. This paper explores the key challenges towards renewable energy in Gulf Cooperation Council countries blessed with plenty of oil and gas reserves. The key challenges identified through literature review were ranked using a quantitative approach through the data collected from a selective sample across the six countries. These challenges in order of importance were found to be policies and regulations, manpower experience and competencies, renewable energy education, public awareness, costs and incentives for renewable energy and government commitment. The findings could be helpful to decision makers and government organisations in the region to develop strategies to overcome these identified challenges

Documents adopted by the International Conference of Communist and Workers' Parties (Moscow, June 5-17, 1969)

The International Labour and Radical History Pamphlet Collection consists of over 2200 pamphlets representing a broad spectrum of leftist opinion, including communists, socialists, liberal reformers, trade unionists, civil libertarians and antiwar activists. The majority of the pamphlets are in English and were published between 1920-1970 in the United States, the Soviet Union, Great Britain, Canada and China. There are also a number of earlier Fabian Society publications. Further information: http://www.library.mun.ca/asc/specialcollections/collections/radica

“Gimme your name and I’ll tell you who you are” An exploration of the name of local lists

The name of a party is an important dimension of its political position. Often, the label used by a political party in its name tells much about its ideology. But, since in most cases, only a few parties compete for each election it is difficult to undertake large qualitative and quantitative analyses of party names. Local elections can provide an interesting option, however. Indeed, in several cases, we find lots of different names, and not only the usual national party labels. In the last local elections in Wallonia, one of the three Belgian Regions, 1012 lists were in competition. Such data provide a fertile ground for analysis. To study the name of the lists, we proceed in two steps. First, we build a typology of the names. We classify the lists in different categories: lists with national party name, lists with a clear reference to a national party, lists with an ideological label, lists with a clear reference to the commune’s name, lists with a reference to the communal level but also lists with a reference to democracy, to a union or alliance, to change and an alternative way of doing politics, to the future, with puns, and with a reference to a person. In the second step, using multinomial regressions, we show where the different types of lists can be found and above all we look at their electoral performances and thus test the hypothesis whether the party name matters or not

Opening the list: the presence of ‘candidates d’ouverture’ at the 2012 local elections in Wallonia

In Belgium, the idea of ‘openness’ is a well spread notion in electoral political discourses and the 2012 local election in Wallonia is no exception to this trend. Despite a clear victory, it is indeed very common for local political leaders in Belgium to announce that they will open their majority to other lists. The idea of ‘openness’ is also part of the local electoral campaign in terms of recruitment: non-partisan candidates – who clearly want to distinguish themselves from the party – are recruited to figure on the lists as ‘independent candidates’. They are called ‘candidates d’ouverture’ as a sign of openness towards the civil society, the opposition, or dissidents from other political parties. Actually, these candidates are recruited for various reasons: there are sometimes used to demonstrate the citizen character of the list, to enhance the fact that the list ‘makes politics differently from established political parties’, to underline the local roots of the list, and sometimes the ‘candidates d’ouverture’ are simply used to complete vacancies on a list
