Part 1: The Congestion of Humanitarian Space
No full textYes¿Part 1: The congestion of humanitarian space¿, assesses what affect the rapid proliferation
of the international aid community¿s presence in Sri Lanka has had on local level
relationships and emergency response capacities. It contends that the burgeoning presence
of aid agencies resulted in humanitarian assistance becoming a hotly contested and
competitive activity. It goes on to identify the possible factors that have contributed to the
rapid congestion of this space in suggesting an explanation of why the humanitarian
communities¿ normative standards appear to have failed

Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
Zumatrichia hazelae Harris and Armitage 2019, new species
No full textZumatrichia hazelae Harris and Armitage, new species Fig. 25 Diagnosis. Zumatrichia hazelae is placed in the galtena group of Flint (1970) based on the presence of a basodorsal process from the inferior appendages similar to that of Z. kerekeda Olah and Flint and Z. kisgula Olah and Flint. However, unlike these two species, Z. hazelae has the basal portion of the inferior appendage short and ovate, similar to that seen in Z. teribe Harris and Armitage. Male. Length 2.7–2.9 mm. Head without modification, a broken with enlarged scape bearing large circular process, body and unmodified wings brown in alcohol. Abdominal segment VII annular with serrate posteroventral mesal process. Segment VIII in lateral view truncate posteroventrally, tapering dorsally; in dorsal view narrow, emarginated posterolaterally; ventrally with narrow mesal incision on posterior margin. Segment IX generally square in lateral view, narrowing anteriorly, posterior margin with thin lobe, laterally with elongate setal-bearing process; dorsally emarginate anteriorly and posteriorly, posterior margins sclerotized. Segment X rectanguloid in lateral aspect; in dorsal view square, with posterior margin tapered. Inferior appendages with elongate, thin basodorsal process, subapically with setal-bearing dorsal lobe, main body an enlarged lobe, which in ventral view is deeply incised posteriorly with numerous setae on margin. Penile sheath with subapical point in lateral view; phallus with medial ring-like process, apically enlarged and platelike, internally with elongate dorsal spine and numerous anterobasal spines; in dorsal aspect, a pair of deeply divided mesal spines, two pair of posterior spines, one mesal, one lateral. Female. Unknown. Type material. Holotype, male— Panama, Bocas del Toro Province, tributary of Quebrada Rambala, Rambala Jungle Lodge, 3.7 km SSE Rambala, 8.91627°N and 82.15469°W, 134 m, November 29, 2014, E. Carlson. Paratype. ibid., 1 male (SCH). Etymology. Named for the mother of the first author, Hazel I. Harris, in honor of her 90 th birthday.Published as part of Harris, Steven C. & Armitage, Brian J., 2019, The Trichoptera of Panama X.

Spatial aspects of the rise of nonmarital fertility across Europe since 1960: the role of states and regions in shaping patterns of change
No full textThis article investigates the role of states and regions in shaping spatial patterns of nonmarital fertility in Europe since 1960 using a dataset of 497 European subnational regions and smaller countries. Almost all regions registered substantial nonmarital fertility increases over the last 50 years. Prior research has shown that in the first half of the twentieth century states played a dominant role in drawing the demographic map of Europe (Watkins, From provinces into nations: demographic integration in Western Europe 1870–1960. Princeton University Press, Princeton, 1991). As a result, subnational regional variation decreased, while differences between countries increased. In this article, we investigate whether states continue to play such a dominant role in delineating patterns of nonmarital fertility between 1960 and 2007. We find that variation in nonmarital fertility levels increased as a whole across Europe, and states continued to be important for determining these patterns. However, the role of states relative to regions declined in the latest period examined (1990 and 2007). Possible explanations for the changes include increased supranational integration, for example, within the European Union, and decentralisation within states leading to increases in variation in subnational contextual conditions.RésuméCet article étudie le rôle des États et des régions dans l’élaboration des modèles spatiaux de fécondité hors mariage en Europe depuis 1960 à l’aide d’un ensemble de données de 497 régions infranationales et petits pays européens. Presque toutes les régions ont enregistré de substantielles augmentations de fécondité hors mariage au cours des 50 dernières années. Une précédente recherche a montré qu’au cours de la première moitié du 20ème siècle, les États ont joué un rôle prédominant dans l’établissement de la carte démographique de l’Europe (Watkins, From provinces into nations: demographic integration in Western Europe 1870–1960. Princeton University Press, Princeton, 1991). En conséquence, la variation infranationale régionale a diminué tandis que les différences entre les pays ont augmenté. Dans cet artiche, nous examinons dans quelle mesure les États continuent à jouer ce rôle prédominant dans la définition des modèles de fécondité hors mariage entre 1960 et 2007. Nous constatons que les niveaux de fécondité hors mariage ont augmenté dans l’ensemble de l’Europe et que les États continuent à jouer un rôle important dans la détermination de ces modèles. Toutefois, le rôle des États par rapport aux régions a diminué au cours de la dernière période étudiée (1990 et 2007). Les explications possibles des changements incluent la croissance de l’intégration supranationale, par exemple au sein de l’Union Européenne, et la décentralisation au sein des États, engendrant une augmentation de la variabilité des conditions contextuelles infranationales
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
The significance of monazite U–Th–Pb age data in metamorphic assemblages; a combined study of monazite and garnet chronometry
No full textIn this study, a coupled U–Th–Pb isotopic and EMP chemical study was carried out in situ on monazite (micro-inclusions within garnet as well as matrix grains) from rocks recovered from two chronologically well-constrained areas of the Himalayan orogen. Monazite inclusions within garnets from three samples yield ages of 44–36 Ma, whereas matrix grains within one sample are typically younger (30–26 Ma). Y depletion of these younger matrix grains indicates that they grew after garnet had crystallised. The recognition of episodic monazite growth during regional metamorphism, first at greenschist facies (before garnet growth) and secondly at upper amphibolite facies (post-dating garnet growth), allows relative growth ages of the occluding garnet to be calculated. These are in excellent agreement with Sm–Nd garnet ages from surrounding units. This approach not only provides a ready means of obtaining porphyroblast growth ages but also allows the combination of precise U–Th–Pb data from metamorphic monazite with thermobarometric information obtained from rock-forming minerals
Dissipative Range Scaling of Higher Order Structure Functions for Velocity and Passive Scalars
No full textDifferently to Kolmogorov's second similarity hypothesis, we find that the 2n-th order velocity and scalar structure functions scale with n-th order moment of the energy dissipation and the scalar dissipation, respectively. The origins of this scaling are analyzed by the transport equations of the fourth order velocity and scalar increment moments and by direct numerical simulations
