Renewable energy innovations and sustainability transition: How relevant are spatial spillovers?

In the societal challenge to switch to renewable energy, innovation has become an ever‐increasing critical determinant. However, while sustainability transition is a global challenge, diffusion and adoption of innovation tends to be uneven in space and unequal access may cause substantial heterogeneity in energy transition. This research analyzes how domestic and foreign innovation activities in the renewable energy sector influence energy transition over time. Empirical testing shows that a country's domestic innovation activity impacts renewable electricity generation capacity sooner than foreign technological innovations. I document that there are substantial barriers to substitute foreign technologies for domestic innovation efforts in the short run but also observe that foreign technologies have a stronger impact after some years. These findings have implications for cross‐border coordination of governmental innovation support and complementary policy instruments that aim at increasing adoption speed across borders.     

Fragmentation as a novel propagation strategy in an Early Ordovician graptolite

VandenBerg, Alfons H.M., November 2017. Fragmentation as a novel propagation strategy in an Early Ordovician graptolite. Alcheringa 42, 1–9. ISSN 0311-5518.

Catenagraptus communalis gen. nov. sp. nov. is a late Floian (Early Ordovician) graptolite from Victoria, Australia, only found as fragments, with each fragment resembling an assemblage of uniserial tubarium-like structures (pseudotubaria) connected by threads (aulons). Individual pseudotubaria consist of a fallosicula and a stipe, both of which are linked by aulons to other pseudotubaria. Adjacent pseudotubaria are in a parent–offspring relationship. Aulons can be generated from both the proximal and distal extremities of fallosiculae, and from the ends of stipes. The aulons are interpreted to have been grown by the zooid that occupied either the fallosicula or the terminal theca of the stipe. Aulons were pathways for a zooid that built a fallosicula at the end of the aulon. This process was repeated to form the assemblage. None of the assemblages contain a true sicula, which suggests that the assemblages present evidence of a new, asexual propagation strategy that involved fragmentation and dispersal. As this interpretation is radical, other models explored are partial sclerotization and modified sicular spines.

The holotype of Pseudisograptus manubriatus manubriatus (Hall, 1914)—implications for the identification of Pseudisograptus manubriatus subspecies

VandenBerg, A.H.M. & Maletz, J., April 2016. The holotype of Pseudisograptus manubriatus manubriatus (Hall, 1914)—implications for the identification of Pseudisograptus manubriatus subspecies. Alcheringa 40, xxx–xxx. ISSN 0311-5518

The holotype of Pseudisograptus manubriatus manubriatus (Hall, 1914) has been rediscovered in the collections of Museum Victoria and is recognized to belong to Pseudisograptus manubriatus harrisi as described by Cooper & Ni (1986). This taxon becomes a junior synonym of P. m. manubriatus. The selected neotype of Pseudisograptus manubriatus manubriatus (Hall, 1914) can be referred to Pseudisograptus manubriatus texanus Cooper & Ni, 1986. The proximal development in all known relief specimens of Pseudisograptus and their descendants indicates that a symmetrical development of the manubrium must be regarded as the rule, and the interpretation of a strong asymmetry in Pseudisograptus manubriatus texanus is rejected.

The Asaba massacre and the Nigerian civil war: reclaiming hidden history

This article explores the consequences of a massacre of civilians in Asaba, a town on the west bank of the river Niger, during the early stages of the Nigerian civil war. While ethnically Igbo, Asaba was not part of the Igbo-dominated Biafra, remaining part of the ethnically diverse midwest region. In the international memory of the war, the midwest action, which claimed several thousand lives, has been eclipsed by the catastrophic events east of the Niger, after the federal blockade of Biafra. This article sheds new light on the human cost of the war on civilian populations outside Biafra. Drawing on interviews with survivors and their descendants, we describe the killings, pillaging and rapes that followed the arrival of the federal troops, and trace the long-term impact and memory of the physical and human devastation in Asaba on family structure, gender roles, educational opportunities and social structure. We show how the official suppression of the massacres, coupled with Biafran awareness of the events, contributed to the subsequent course of the war, and we suggest that this suppression has left a legacy that perpetuates resentment and has kept ethnic tensions alive to this day.     

苏格兰 以自由之名出发

时下,最热门的电影都和苏格兰有关——《Elizabeth》和《The Water Horse:Legend of the Deep》,一部关于历史,一部关于风光,可以说,这两者就是苏格兰的命脉。作为英联邦的一部分,苏格兰人一直不那么热爱女王陛下。几百年来,苏格兰就像一个处于叛逆期的少年,以自由的名义倔强地存在着。这里因此变得更加有趣:从低地到高地,从QueenMary到伊丽莎白,苏格兰不仅仅只有风笛、方格裙子和牧羊犬,更多的故事让这里变得更加让人神往……     

Citizenship at war: Passports and nationality in the 2008 Russian‐Georgian conflict (Respond to this article at http://www.therai.org.uk/at/debate)

By analyzing the 2008 war between Russia and Georgia, this paper stretches the limits of the anthropology of war and citizenship. Trying to overcome anthropologists' usual unease about commenting on ‘big topics’, I examine citizenship policies ‘from above’ and ‘from below’ that potentially lead to conflict and war. Special attention is paid to the role of nationality as a crucial feature of post‐Soviet citizenship, and to citizenship as an effective means of neo‐imperial expansion. In my conclusion, I contextualize my findings within anthropological debates about citizenship and argue that the recent stress on rights and entitlements needs to be balanced by an analysis of the repressive dimensions of citizenship regimes.     

Use of robust methods to determine quadratic surfaces: application to heritage

3D surveys of archaeological elements and the construction of virtual models enable us to reconstruct historical sites. They provide useful data to select specific building processes.Photogrammetry and Terrestrial Laser Scanning (TLS) are the most common techniques to obtain synthetically heritage models. These techniques provide massive data which can only be managed by replacing them by primitive shapes, thereby obtaining more simple models and the explicit geometry of the element. Statistical and robust methods are used for this substitution, thereby avoiding the common errors due to measuring. Of these methods, the most widely used are the least-median-of-squares (LMedS) and the RANSAC method.Another computation method consists in recursive processes based on evolutive-type algorithms to adjust the model to the data captured.This paper describes two surface computation methodologies to determine the modelling of a column shaft located in temple G of the archaeological park of Selinunte (Sicily).
