Roots of an Archean volcanic arc complex: the Lac des Iles area in Ontario, Canada
1997
Abstract The Lac des Iles area is located in the Wabigoon Subprovince, an Archean granite-greenstone terrain in the Superior Province in Ontario, Canada. The area consists of several unmetamorphosed plutons of biotite- and hornblende-tonalite and mafic and ultramafic intrusions which are emplaced into an older tonalitic gneiss. The mafic/ultramafic bodies are concentric in shape and consist of periodotite, pyroxenite, gabbro and hornblende gabbro cumulates and diorite. The largest intrusion, the Lac des Iles complex, consists of several mafic and ultramafic centers. An internal SmNd isochron from the southern ultramafic complex gives an intrusion age of 2736 ± 28 Ma (MSWD = 1.5; ϵNd(t) = 1…
Geochemical characteristics of Archaean and Late Proterozoic to Palaeozoic fine-grained sediments from Southern Africa and significance for the evolu…
1985
Chemical data for pelitic rocks (shallow-marine platform sediments) of the ∼ 2.9 Ga old Pongola Supergroup, South Africa, and the 550–700 Ma old Nama Group, Namibia, revealed clearly different compositions in both groups. A comparison of the Pongola and Nama data with literature values for sedimentary rocks shows a trend for Cr/TiO2 and Cr/Zn ratios as well as the absolute Cr and Ni concentrations to lower values with decreasing age, whereas the Cr/Ni ratios seem to remain broadly constant through time. REE patterns of Pongola and Nama sediments show no significant difference, thus giving the impression of a post-Archaean origin for the demonstrably Archaean Pongola sediments. However, a pl…
Mikä tekee perheestä perheen? : viidesluokkalaisten käsityksiä perheestä
2017
Tutkielman tarkoituksena on selvittää viidesluokkalaisen käsityksiä perheestä. Käsityksiä pyritään löytämään viidesluokkalaisten tuottamien perhepiirustusten avulla. Piirustusten tueksi tutkielman aineistoa täydentävänä osana toimii viidesluokkalaisen vastaukset kysymykseen: Mikä tekee perheestä perheen? Tutkielmaan osallistui 28 viidennen luokan oppilasta. Aineisto kerättiin erään keskipohjanmaalaisen alakoulun kolmelta eri viidenneltä luokalta keväällä 2017. Oppilaat tuottivat perhepiirustuksen ja vastasivat kysymykseen ”Mikä tekee perheestä perheen?”, kukin ryhmä kolmen eri oppitunnin aikana. Aineisto analysoitiin fenomenografisen analyysin mukaisesti. Fenomenografisen analyysin pohjalta…
The role of perspective on students’ use of multiple documents to solve an openended Task
2013
AbstractMcCrudden & Schraw (2007) show how students’ interaction with a text is mediated by the instructions they are presented with. Specifically, perspective instructions prompt readers to use background knowledge to evaluate text from an assigned point of view. Research on perspective in single texts has demonstrated that readers confer relevance on text segments that are consistent with the assigned perspective (Pichert & Anderson, 1977). This work has tested the effects of perspective when reading conflicting information from multiple documents to perform an open-ended task, as well as has studied if the trustworthiness of a source exerts any influence on students’ decision to use info…
Testing-the-Waters Policy With Hypothetical Investment: Evidence From Equity Crowdfunding
2020
International audience; Digitization has enabled “testing-the-waters” in entrepreneurial finance whereby investors can make nonbinding commitments in equity crowdfunding prior to an actual campaign to ascertain interest in the project. We consider whether these nonbinding equity investment commitments are informative about actual investments during the campaign and, thus, ultimate startup funding success. The data indicate that only 18% of nonbinding commitments are, in fact, invested. The evidence is consistent with hypothetical bias. Hypothetical bias is significantly less pronounced among women and among investors living in higher income areas or in areas with higher levels of education.…

Direct Compensation and Risk Management: A Key Study from the Insurance Sector
2019
This paper examines the business model of an Italian company (TIS) that manage the claims for non-life insurance companies with innovative solutions. When a policy-holder make a claim for a loss or damage, the insurer may decide either to repair, rebuild or replace the property or to offer a cash settlement. To provide these services, many insurance companies have started developing strategic relationships directly with building firms, repairers, specialist suppliers and project managers, in order to find reliable contractors that will repair or replace the policy holder’s property quickly, with high quality and at a low cost. Opposite to other EU Countries, in Italy many insurance companie…
Sustainable and Conventional Banking in Europe
2020
At the end of the 20th century a new banking model, the so-called ethical banking, emerged becoming the maximum exponent of a socially responsible investment. The financial crisis in 2008 led to a distrust of the conventional financial system and consequently investors began to look with interest this new banking, which only invests in ethical activities and products, with social and environmental criteria, total transparency and a democratic management. The aim of this article is to analyze the economic structure of ethical banking, compared to that of conventional banking, by paying attention to its liquidity, coverage and solvency. Specifically, We compare the financial statements of Tri…
Cartels Uncovered
2018
How many cartels are there? The answer is important in assessing the efficiency of competition policy. We present a Hidden Markov Model that answers the question, taking into account that often we do not know whether a cartel exists in an industry or not. Our model identifies key policy parameters from data generated under different competition policy regimes and may be used with time-series or panel data. We take the model to data from a period of legal cartels - Finnish manufacturing industries 1951 - 1990. Our estimates suggest that by the end of the period, almost all industries were cartelized.
Evolution of Cambrian and Early Ordovician arcs in the Kyrgyz North Tianshan: Insights from U-Pb zircon ages and geochemical data
2019
Abstract Geochronological, geochemical, and structural studies of magmatic and metamorphic complexes within the Kyrgyz North Tianshan (NTS) revealed an extensive area of early Palaeozoic magmatism with an age range of 540–475 Ma. During the first episode at 540–510 Ma, magmatism likely occurred in an intraplate setting within the NTS microcontinent and in an oceanic arc setting within the Kyrgyz-Terskey zone in the south. During the second episode at 500–475 Ma, the entire NTS represented an arc system. These two phases of magmatism were separated by an episode of accretionary tectonics of uncertain nature, which led to obduction of ophiolites from the Kyrgyz-Terskey zone onto the microcont…
