Business school techspectations Technology in the daily lives and educational experiences of business students
No full textBusiness School Techspectations is the second in a series of reports based on research by the DCU Leadership, Innovation and Knowledge Research Centre (LInK) at DCU Business School. With its roots in an Irish business school, it is no surprise that LInK’s mission is to strengthen the competitiveness, productivity, innovation and entrepreneurial capacity of the Irish economy. Ireland’s next generation transformation will be enabled by information and communication technologies (ICT) and digital participation by members of Irish society. As a university research centre we have an important role to play in supporting education, industry and government to accelerate this transformation
Uporaba produktov reanaliz za namen hidrološkega modeliranja: izbrani primeri v Sloveniji
No full textHidrološko modeliranje nemerjenih porečij je še vedno velik izziv, saj za taka porečja ni na voljo ali podatkov o pretokih ali podatkov o padavanih in temperaturi zraka. V zadnjih letih je bilo na tem področju narejenih veliko raziskav. Ena izmed metod, ki jih lahko uporabimo namesto točkovno merjenih podatkov, so podatki reanaliz, ki združujejo modelske izračune, točkovne meritve ter tudi satelitske in radarske podatke.
Magistrska naloga analizira ustreznost dveh produktov reanaliz z vidika ustreznosti podatkov opadavinah in temperaturi zraka. Izbrana sta dva produkta, in sicer ERA5 in COSMO-REA6,ki sta v nalogi testirana na izbranih porečjih na območju Slovenije. Oba produkta imata na voljopodatke z urnim časovnim korakom in do sedaj z vidika hidrološkega modeliranja površinskegaodtoka še nista bila preverjena. Za modeliranje sta uporabljena enovita konceptualna modelaGR4H in CemaNeigeGR4H. Testirane so različne konfiguracije modelov (npr. s ponovnimumerjanjem ali brez le-tega).
Ugotovljeno je bilo, da so podatki reanaliz primerni za uporabo samo za nekatera porečja, in sicer v primeru da hidrološki model ni ponovno umerjen na podatke reanaliz, ampak se privzame parametre, določene glede na točkovno izmerjene podatke. Ponovno umerjanje modela pa je izboljšalo rezultate modeliranja. Rezultati so pokazali, da se izbrana produkta reanaliz delno ujemata s točkovno izmerjenimi podatki, kar pomeni da ju lahko upoorabimo kot grobo oceno dejanskega stanja v primeru, da podatkov o padavinah in temperaturi zraka ni na razpolago.The need for hydrological modeling in ungauged basins has always been a major challenge. Efforts have been made in recent years to address it via the implementation of ex-situ technologies. An attractive option that is becoming increasingly popular are reanalysis products, which provide modeled data for atmospheric variables, based on observations assimilated from various sources, such as satellites and radar stations. The present study is focusing on the evaluation of two reanalysis precipitation and temperature datasets, namely ERA5 and COSMO-REA6, over a selection of drainage basins located in Slovenia. The two products are available at the hourly temporal scale, and at the time of writing, their quality has not been evaluated in rainfall-runoff applications over European borders. To measure their efficiency, the GR4H and GR4H Cema Neige lumped conceptual rainfall-runoff models were used. Different reanalysis configurations were tested by using the initial model parameters, calibrated using observed data. In addition, it was investigated whether the parameters ingrained within the model are able to make up for low rainfall and temperature data quality, by recalibrating them on every reanalysis configuration. Initial model runs proved to be adequate only for a few catchments out of the total selection. However, the recalibration process was effective in increasing hydrological performance, increasing the total number of watersheds that were modeled accurately. The study concluded that the two products are partially in agreement with observations, suggesting their use as a proxy when observed data is scarce
Management Matters
No full textNew indications of managerial innovations are created and then used to show that changes in organizational technologies are an important source of economic growth. Specifically, the analysis demonstrates that, first, in response to a positive managerial technology shock, output, productivity and hours significantly increase in the short run, second, these types of innovations are as important as non-managerial ones in explaining movements in these variables at business cycle frequencies, and, third, product and process innovations promote the development of new managerial techniques.Business Cycles; Productivity; Management techniques; Technical Change
Bayesian forecasting of mortality rates by using latent Gaussian models
No full textWe provide forecasts for mortality rates by using two different approaches. First we employ dynamic non-linear logistic models based on the Heligman–Pollard formula. Second, we assume that the dynamics of the mortality rates can be modelled through a Gaussian Markov random field. We use efficient Bayesian methods to estimate the parameters and the latent states of the models proposed. Both methodologies are tested with past data and are used to forecast mortality rates both for large (UK and Wales) and small (New Zealand) populations up to 21 years ahead. We demonstrate that predictions for individual survivor functions and other posterior summaries of demographic and actuarial interest are readily obtained. Our results are compared with other competing forecasting methods.</p
Taxonomic Keys and Plates from The Myxomycetes
No full textDigital work, reproduction of text and layout by Rojas Alvarado, Carlos y Lado Rodríguez, CarlosIn 1969, George W. Martin and Constantine J. Alexopoulos published a remarkable work on myxomycetes. Their monograph on this group of organisms became one of the references to the taxonomy and geographical distribution of the species in the world. The impact of this book was large, partially because they reviewed the previous works of Thomas Macbride (a large number of collections observed by Martin & Alexopoulos were collected by the former) and Arthur and Gulielma Lister (who sent European collections to the United States National Herbarium). In this manner, The Myxomycetes by Martin & Alexopoulos was in some ways, an update of the information already published in the books North American Slime-Moulds by Thomas Macbride (1922) and Monograph of the Mycetozoa by Arthur Lister (first edition in 1894).
The original Martin & Alexopoulos The Myxomycetes book is found today in bookshelves of myxomycete researchers and institutional libraries around the world. It is the last worldwide monograph on myxomycetes. Despite being widely used for research purposes, the book has been out of print for many years and the younger generation of people interested in the fascinating world of myxomycetes has limited access to it. Both Macbride´s and Lister´s books have been rescued by the Biodiversity Heritage Library and can be accessed in digital format today, but The Myxomycetes by Martin & Alexopoulos is not available on the internet yet.
Aware of that limitation, we obtained permission from the original publisher (University of Iowa Press) to create a digital version of the taxonomic keys and original plates contained in the book. Even though molecular techniques of myxomycete detection have been reshaping the nomenclature of the group in recent years and a number of binomials have changed over time, the original work published more than 50 years ago still offers important clues for taxonomic purposes. The drawings are much less detailed than those in Lister´s book, for example, but they are still useful for identification. However, they keys are comprehensive, detailed, and easy to use.
We hope this digital compilation would contribute, even a little, to increase the access to scientific information in regions of the world where the original book has been difficult to read. We know it is not the same as having the actual book in your hands, but it is pretty close.Ministerio de Ciencia e Innovación de España/PGC2018-094660-B-I00//EspañaUCR::Sedes Regionales::Sede del Atlántico::Recinto de Paraíso::Finca Experimental Interdisciplinaria de Modelos Agroecológicos (FEIMA
