Product differentiation in the socially responsible mutual fund industry

In this study, we analyse the effect of product differentiation on prices and clients’ attraction in the socially responsible (SR) mutual fund industry. Using three proxies for differentiation, including a text-based indicator, a return-based indicator, and a portfolio-holding indicator, we analyse a sample of US SR equity mutual funds in the period 1999–2019. Our findings show that the text differentiation measure better explains the product differentiation impact on prices and flows than the measures based on funds’ characteristics. Our text differentiation results indicate that younger SR funds and funds belonging to smaller families are more differentiated. In addition, differentiation allows SR funds to charge higher fees and attract more money flows. Finally, our results indicate that SR fund investors are sensitive to differentiation regarding other funds implementing the same SR strategies, but not in relation to other funds in the same Morningstar financial style category

Applicability of extracts from Centaurea calcitrapa in ripening of bovine cheese

Aqueous extracts obtained from cell suspension cultures of Centaurea calcitrapa were used as proteolytic additive in the manufacture of a commercial bovine cheese, coagulated with animal rennet and typically ripened for 28 d. The cheese was assessed in comparison to standard cheese for two levels of addition of said extract, viz. 0.61 and 1.22mg of total protein mL~1. The qualitative and quantitative evolutions of the nitrogen fractions were monitored in the experimental cheeses throughout the whole ripening period. In general, the chemical compositions of the cheeses were di!erent depending on the amount of extract used, but no signi"cant di!erences could be detected in the ripening index. With regard to electrophoretic pro"les, the two types of cheese could be distinguished until up to ca. 7 d of ripening, but di!erences did essentially vanish by 28 d

Phylogenomics of pike cichlids (Cichlidae: Crenicichla): the rapid ecological speciation of an incipient species flock

© 2017 European Society For Evolutionary Biology. Journal of Evolutionary Biology © 2017 European Society For Evolutionary Biology The rapid rise of phenotypic and ecological diversity in independent lake-dwelling groups of cichlids is emblematic of the East African Great Lakes. In this study, we show that similar ecologically based diversification has occurred in pike cichlids (Crenicichla) throughout the Uruguay River drainage of South America. We collected genomic data from nearly 500 ultraconserved element (UCEs) loci and \u3e260 000 base pairs across 33 species, to obtain a phylogenetic hypothesis for the major species groups and to evaluate the relationships and genetic structure among five closely related, endemic, co-occurring species (the Uruguay River species flock; URSF). Additionally, we evaluated ecological divergence of the URSF based on body and lower pharyngeal jaw (LPJ) shape and gut contents. Across the genus, we recovered novel relationships among the species groups. We found strong support for the monophyly of the URSF; however, relationships among these species remain problematic, likely because of the rapid and recent evolution of this clade. Clustered co-ancestry analysis recovered most species as well delimited genetic groups. The URSF species exhibit species-specific body and LPJ shapes associated with specialized trophic roles. Collectively, our results suggest that the URSF consists of incipient species that arose via ecological speciation associated with the exploration of novel trophic roles

Geo-imagery management and statistical processing in a regional context using Open Data Cube

We propose a methodology to manage and process remote sensing and geo-imagery data for non-expert users. The proposed system provides automated data ingestion and manipulation capability for analytical data-driven purposes. In this paper, we describe the technological basis of the proposed method in addition to describing the tool architecture, the inherent data flow, and its operation in a specific use case to provide statistical summaries of Sentinel-2 regions of interest corresponding to the cultivation of polygonal areas located in the Basque Country (ES).Comment: 4 pages, 4 figures, Published in 2021 IEEE International Geoscience and Remote Sensing Symposium IGARS

Caseinolytic activity of fruit extract from Opuntia ficus-indica on bovine, caprine, and ovine Sodium Caseinates

The rates and extents of hydrolysis of RS- and â-caseins from bovine, caprine, and ovine sodium caseinates produced by an enzymatic extract of the fruit of Opuntia ficusindica, (L.) Miller were evaluated and compared with those produced by a commercial animal rennet. A mechanistic model based on a pseudo-first-order enzymatic reaction, in the presence of first-order deactivation of the enzyme, was postulated and successfully fitted to the experimental data. The animal rennet exhibited higher enzymatic efficiency than the fruit extract, irrespective of the source (i.e., bovine, caprine, or ovine) and the type (i.e., RS- or â-casein) of substrate. The enzymatic efficiency (kcat/Km) for RS-casein ranged from 72 to 220 and from 43 to 65 L g-1 h-1, and for â-casein from 242 to 742 and from 55 to 164 L g-1 h-1, for the animal rennet and the enzymatic extract of O. ficus-indica, respectively. Finally, it was observed that â-casein from caprine and ovine caseinates was degraded by O. ficus-indica faster than its RS counterpart, but the reverse was observed for bovine caseinate

Holistic Support for the Collaborative Planning of Fire Protection Concepts in Building Design

Der Bauplanungsprozess ist durch ein hohes Maß an Kooperation zwischen Planungsbeteiligten verschiedener Fachrichtungen gekennzeichnet. Hierbei werden zum einen Planungen auf der Basis von Planungsinformationen anderer Planungsbeteiligter detailliert, zum anderen geben Planungen einzelner auch wichtige Rahmenbedingungen für die Gesamtplanung vor. Der vorliegende Beitrag beschreibt einen Ansatz zur ganzheitlichen Unterstützungen verteilter Planungen am Beispiel des baulichen Brandschutzes. Der Antrag trägt hierbei der verteilten und parallelen Planung Rechnung, wie sie heute bei der Planung großer und mittlerer Bauwerke angewendet wird. Die Verteiltheit wird nicht nur für die Planungsbeteiligten modelliert, sondern auch die einzelnen Planungsinformationen liegen im gemeinsamen Kooperationsverbund verteilt vor. Der Fokus dieses Beitrags liegt auf der Wahrnehmung von Planungsänderungen und Ereignissen während der Planung und die Verarbeitung dieser Informationen um eine durchgängige Planung zu gewährleisten. Dies wird zum einen durch das CoBE Awarenessmodell erreicht, mit dem Ereignisse erkannt und dem Informationsverbund zur Verfügung gestellt werden können. Zum anderen werden die Ereignisbehandlung und die darauf folgende fachgerechte Informationsverarbeitung mit Hilfe eines Multi-Agentensystems beschrieben
