Una peste de viruelas en la región de la frontera de Guerra hispano-indígena en el Reino de Chile (1791)

ResumenEn la frontera de guerra del río Bío Bío se enfrentaron dos sociedades totalmente diferentes: la sociedad colonial hispánica contra los mapuches y otras sociedades indígenas. El análisis de los documentos sobre la peste general de viruelas que se desató en la región de frontera en 1791, permite al autor adentrarse en el conocimiento de aquellas sociedades.AbstractTwo completely different societies confronted each other on the military frontier of the Bío Bío River: Hispanic colonial society and that of the Mapuches and other Indian societies. An analysis of the documents on the widespread small pocks epidemic of the frontier region in 1791 allows the author to study those two societies in contact.

Efficient microwave hydrothermal preparation of nanocrystalline anatase TiO2 colloids

Titanium dioxide nanocrystals are an important commercial product used primarily in white pigments and abrasives, however, more recently the anatase form of TiO2 has become a major component in electrochemical and photoelectrochemical devices. An important property of titanium dioxide nanocrystals for electrical applications is the degree of crystallinity. Numerous preparation methods exist for the production of highly crystalline TiO2 particles. The majority of these processes require long reaction times, high pressures and temperatures (450–1400 °C). Recently, hydrothermal treatment of colloidal TiO2 suspensions has been shown to produce quality crystalline products at low temperatures (<250 °C). In this paper we extend this idea utilising a direct microwave heating source. A comparison between convection and microwave hydrothermal treatment of colloidal TiO2 is presented. The resulting highly crystalline TiO2 colloids were characterised using Raman spectroscopy, XRD, TEM, and electron diffraction. The results show that the microwave treatment of colloidal TiO2 gives comparable increases in crystallinity with respect to normal hydrothermal treatments while requiring significantly less time and energy than the hydrothermal convection treatment.

Handbook of service description

With the growth in number and sophistication of services widely available, there is a new urgency for comprehensive service descriptions that take into account both technical and business aspects. The last years have seen a number of efforts for best-of-breed service description focusing on specific aspects of services. The Handbook of Service Description provides the most advanced state of the art insights into these. The main parts of the book provide the most detailed documentation of the Unified Service Description Language (USDL) to date. USDL has been developed across several research institutes and publicly funded projects across Europe and Australia, currently extending to the Americas as part of a standardization push through W3C. The scope of services extends across IT and business, i.e., the socio-technical sense of services scaled to business networks. In this respect, purely human, purely automated and mixed human/automated services were considered, that have a boundary of cognizance that is available through the tasks of service provisioning, discovery, access and delivery. Taken together, the Handbook of Service Description provides a comprehensive reference suitable for a wide-reaching audience including researchers, practitioners, managers, and students who aspire to learn about or to create a deeper scientific foundation for service description and its methodological aspects.

The internet of services and USDL

A prominent research focus, especially in the context of EU public funding, has been the systematic use of the Internet for new ways of value creation in the services sector. This idea of service networks in the Internet, frequently dubbed the Internet of Services or Web service ecosystems, wants to make services tradable in digital media. In order to enable communication and trade between providers and consumers of services, the Internet of Services requires a standard that creates a "commercial envelope" around a service. This is where the Unified Service Description Language (USDL) comes into play as a normative and balanced unification of service information. The unified description established by USDL is machine-processable, considers technical and business aspects of a service as well as functional and non-functional attributes.

Representing USDL for humans and tools

This chapter deals with technical aspects of how USDL service descriptions can be read from and written to different representations for use by humans and tools. A combination of techniques for representing and exchanging USDL have been drawn from Model-Driven Engineering and Semantic Web technologies. The USDL language's structural definition is specified as a MOF meta-model, but some modules were originally defined using the OWL language from the Semantic Web community and translated to the meta-model format. We begin with the important topic of serializing USDL descriptions into XML, so that they can be exchanged beween editors, repositories, and other tools. The following topic is how USDL can be made available through the Semantic Web as a network of linked data, connected via URIs. Finally, consideration is given to human-readable representations of USDL descriptions, and how they can be generated, in large part, from the contents of a stored USDL model.

SOA approaches

As the service-oriented architecture paradigm has become ever more popular, different standardization efforts have been proposed by various consortia to enable interaction among heterongeneous environments through this paradigm. This chapter will overview the most prevalent of these SOA approaches. It will first show how technical services can be described, how they can interact with each other and be discovered by users. Next, the chapter will present different standards to facilitate service composition and to design service-oriented environments in light of a universal understanding of service orientation. The chapter will conclude with a summary and a discussion on the limitations of the reviewed standards along their ability to describe service properties. This paves the way to the next chapters where the USDL standard will be presented, which aims to lift such limitations.

Design overview of USDL

Enabling web-based service networks and ecosystems requires a way of describing services by a "commercial envelope" as discussed in Chapter 1. A uniform conception of services across all walks of life (including technical services) is required capturing business, operational and technical aspects. Therefore, our proposed Unified Service Description Language (USDL) particularly draws from and generalizes the best-of-breed approaches presented in Part I. The following chapter presents the design rationale of USDL where the different aspects are put in a framework of descriptions requirements. This is followed by the subsequent chapters of this part that provide details on specific aspects such as pricing or legal issues.

Diversity of dicotyledenous-infecting geminiviruses and their associated DNA molecules in Southern Africa, including the South-west Indian Ocean Islands

The family Geminiviridae comprises a group of plant-infecting circular ssDNA viruses that severely constrain agricultural production throughout the temperate regions of the world, and are a particularly serious threat to food security in sub-Saharan Africa. While geminiviruses exhibit considerable diversity in terms of their nucleotide sequences, genome structures, host ranges and insect vectors, the best characterised and economically most important of these viruses are those in the genus Begomovirus. Whereas begomoviruses are generally considered to be either monopartite (one ssDNA component) or bipartite (two circular ssDNA components called DNA-A and DNA-B), many apparently monopartite begomoviruses are associated with additional subviral ssDNA satellite components, called alpha- (DNA-αs) or betasatellites (DNA-βs). Additionally, subgenomic molecules, also known as defective interfering (DIs) DNAs that are usually derived from the parent helper virus through deletions of parts of its genome, are also associated with bipartite and monopartite begomoviruses. The past three decades have witnessed the emergence and diversification of various new begomoviral species and associated DI DNAs, in southern Africa, East Africa, and proximal Indian Ocean islands, which today threaten important vegetable and commercial crops such as, tobacco, cassava, tomato, sweet potato, and beans. This review aims to describe what is known about these viruses and their impacts on sustainable production in this sensitive region of the world. © 2012 by the authors licensee MDPI, Basel, Switzerland.

Consumer Internet purchasing behaviour in Chile

Despite the potential for e-commerce growth in Latin America, studies investigating factors that influence consumers’ Internet purchasing behavior are very limited. This research addresses this limitation with a consumer centric study in Chile using the Theory of Reasoned Action. The study examines Chilean consumers’ beliefs, perceptions of risk, and subjective norms about continued purchasing on the Internet. Findings show that consumers’ attitude towards purchasing on the Internet is an influential factor on intentions to continue Internet purchasing. Additionally, compatibility and result demonstrability are influential factors on attitudes towards this behavior. The study contributes to the important area of technology post adoption behavior.

Agent-based modelling simulation case study : assessment of airport check-in and evacuation process by considering group travel behaviour of air passengers

Passenger experience has become a major factor that influences the success of an airport. In this context, passenger flow simulation has been used in designing and managing airports. However, most passenger flow simulations failed to consider the group dynamics when developing passenger flow models. In this paper, an agent-based model is presented to simulate passenger behaviour at the airport check-in and evacuation process. The simulation results show that the passenger behaviour can have significant influences on the performance and utilisation of services in airport terminals. The model was created using AnyLogic software and its parameters were initialised using recent research data published in the literature.

kmth price sealed-bid auctions with general independent values and equilibrium linear mark-ups

A generalised bidding model is developed to calculate a bidder’s expected profit and auctioners expected revenue/payment for both a General Independent Value and Independent Private Value (IPV) kmth price sealed-bid auction (where the mth bidder wins at the kth bid payment) using a linear (affine) mark-up function. The Common Value (CV) assumption, and highbid and lowbid symmetric and asymmetric First Price Auctions and Second Price Auctions are included as special cases. The optimal n bidder symmetric analytical results are then provided for the uniform IPV and CV models in equilibrium. Final comments concern implications, the assumptions involved and prospects for further research.

ACE research briefing paper 009: Global Entrepreneurship Monitor: GEM Australia - 2014 National Report

Most policymakers and academics agree that entrepreneurship is critical to the development and wellbeing of society. Entrepreneurs create jobs. They drive and shape innovation, thereby speeding up structural changes in the economy. By introducing new competition they contribute indirectly to increased productivity and overall economic activity. Entrepreneurship is thus a catalyst for economic growth and national competitiveness. In 2014, the Global Entrepreneurship Monitor (GEM)conducted its 15th annual survey of the rate and profile of entrepreneurial activity around the globe. GEM interviewed over 206,000 adults aged 18–64 in 70 economies, spanning diverse geographies and a range of development levels. The Australian Centre for Entrepreneurship Research (ACE) participated as the Australian GEM partner, surveying 2,177 Australian adults. This report provides a summary of entrepreneurship in Australia as measured by GEM, and benchmarks this against other countries. We compare the level of entrepreneurship in the population across different phases of the entrepreneurial process, and provide a profile of some key characteristics of entrepreneurs and the businesses they are starting. We also report on some of the institutional and framework conditions that support entrepreneurship.

Konstteoretikern och livet : Mikael Lybecks Breven till Cecilia i nietzscheansk belysning

I avhandlingen analyseras den finlandssvenska författaren Mikael Lybecks (1864-1925) verk Breven till Cecilia. Denna brevroman hör till Lybecks senare produktion och utkom 1920. Verket har kommit att betraktas som en klassiker inom den finlandssvenska litteraturen. Av författarensövriga produktion är det strängt taget endast Tomas Indal (1911) som haft en jämförbar genomslagskraft. Trots detta har romanen inte varit föremål för en enda mer omfattande studie. l sin Lybeckbiografi relaterar Erik Kihlman i första hand verket till det biografiska och till samhällssituationen vid tiden för romanens tillkomst. Vetenskapen, konsten och livet bildar tillsammans den triangel som utgör romanens stomme. Antiken är starkt närvarande i romanen och med begrepp som härrör från denna era kan man tala om det sokratiska, det apollinska och det dionysiska. Detta är begrepp som Friedrich Nietzsche utgår i från i sitt ungdomsverk Tragedins födelse (Die Geburt der Tragödie aus dem Geiste der Musik) från 1872. Nietzsches vetenskapskritik och hans syn på den högsta konsten som ett brödraförbund mellan Dionysos och Apollon står i förvånansvärt hög grad i samklang med den övergripande tematiken i Lybecks verk. När Nietzsche därtill framhäver musiken som grunden förall konst får många inslag i romanen sin förklaring. l Breven till Cecilia skildras en vändpunkt i huvudpersonen Sven Ingelets liv. Därför ligger tyngdpunkten i den tematiska analysen vid det som gör att verket kan betraktas som en utvecklingsroman. Även om romanen skildrar en tidsperiod på endast ett och ett halvt år så hinnerhuvudpersonen ändå undergå en betydande personlighetsförändring. Nietzsches Tragedinsfödelse med dess ovannämnda grundläggande begrepp lämpar sig ypperligt som referensram för en analys av denna förändring. Avhandlingen har också strukturerats utgående från de nietzscheanska begreppen sokratiskt, dionysiskt och apollinskt vilka alltså återspeglar huvudpersonens utvecklingsfaser. Från att ha varit en renodlad förnuftsmänniska väcks Sven Ingelet genom ett kortvarigt kärleksförhållande till det dionysiska med allt vad det innebär av känslorus och lidande. Att Ingelet nästan helt uppgått i sin roll som konstteoretiker har medfört att hans förhållningssätt till omvärlden utmärks av intresselös betraktelse. Till följd av sin viljesvaghet och bristande handlingskraft måstehan försöka behålla sin älskades gunst genom magiska pseudohandlingar. Detta leder in Ingelet i myternas värld. Hans verklighetsuppfattning får andra dimensioner än den vetenskapliga. Det dionysiska uppvaknandet medför tillsammans med det efterföljande brevskrivandet att Ingeletnår fram till en självkännedom och upphör att vara en främling i tillvaron. Ingelet utvecklar ocksåen ny konstsyn som förutsätter ett samband mellan konsten och livet. Detta apollinska utvecklingsstadium kännetecknas också av sanningsförmedlande drömmar, och av en tilltagande resignation som till slut utmynnar i ett självmord. Nyckelord: brevroman, Dionysos, Apollon, främlingskap, verklighetsflykt

Cynodon dactylon, Green Couch Grass 'Oz-E-Green'

Spontaneous mutation or chance seedling: discovered in 2001 as a superior plant growing among “Common” green couch on the breeder’s turf farm at Berries Road, Childers. A selected piece of sod was removed and broken into vegetative sprigs to propagate a larger area of this variety elsewhere on the breeder’s property. The original plant has now been multiplied vegetatively three times without showing any discernible off types. Selection criteria: dense prostrate habit and limited inflorescence production (giving a low mowing requirement), high turf quality, dark green colour. Propagation: vegetative. Breeder: Robert William Morrow, Childers, QLD. PBR Certificate Number 2844, Application Number 2004/035, granted 22 August 2005.
