Una definició de talent: orientadora per a la seua gestió a l’empresa i base per a la RSU
2019
espanolEl objetivo de este articulo es delimitar el significado y alcance del concepto talento en el mundo de la empresa, como punto de partida para que las organizaciones implicadas en el desarrollo sostenible de la sociedad y la economia del pais –en especial las universidades y las empresas– cumplan con la responsabilidad que tienen frente a la sociedad en la que influyen. Pretende que los stakeholders implicados la tomen como el punto de partida para construir una nueva manera de hacer y de trabajar en el desarrollo de las personas en las empresas, por ende, en las comunidades y la sociedad en general. Este articulo bebe de la literatura academica especializada y publicada en revistas d…
Active degassing of crustal CO2 in areas of tectonic collision: A case study from the Pollino and Calabria sectors (Southern Italy)
2022
Carbon dioxide (CO2) is released from the Earth’s interior into the atmosphere through both volcanic and non-volcanic sources in a variety of tectonic settings. A quantitative understanding of CO2 outgassing fluxes in different geological settings is thus critical for decoding the link between the global carbon budget and different natural processes (e.g., volcanic eruption and earthquake nucleation) and the effects on the climate evolution over geological time. It has recently been proposed that CO2 degassing from non-volcanic areas is a major component of the natural CO2 emission budget, but available data are still sparse and incomplete. Here, we report the results of a geochemical surve…
An Autonomous System to Take Angular Thermal-Infrared Measurements for Validating Satellite Products
2015
An autonomous system for field land surface temperature (LST) measurements taken at different observation angles was developed to be deployed easily at any conventional meteorological tower station. The system permits ground-truth data to be acquired on a continuous basis, and angularly scans land and sky hemispheres with a single thermal-infrared (TIR) radiometer. This paper describes the autonomous angular system and the methodology to assess ground-truth LST and relative-to-nadir emissivity data from system measurements. Ground-truth LSTs were used to validate satellite-retrieved LST products at two experimental sites (rice crop and shrubland areas). The relative-to-nadir emissivity valu…
Samtal om Budkavlen : hågkomster från 1970–1990-talen
2022
Med anledning av Budkavlens 100-årsjubileum fick jag i uppdrag att intervjua två av tidskriftens tidigare medarbetare – professor emeritus Nils Storå och intendent John Hackman – om deras erfarenheter av utgivningen av tidskriften under 1970–1990-talen. Nils Storå (f. 1933) var professor i nordisk etnologi under åren 1972–1997 och John Hackman (f. 1942) var amanuens vid Sjöhistoriska museet 1972–1975 och därefter intendent vid Etnologiska institutionen fram till sin pensionering 2005. Texten nedan ger en bild av hur det var att driva en humanistisk vetenskaplig tidskrift under 1900-talets sista decennier. Samtalet som återges är fiktivt i den meningen att jag valt att placera mina frågor oc…
Conjunctions and syntactic complexity: Development of the use of conjunctions in written learner Finnish
2022
Kielitaidon kehittymistä voidaan tutkia mittaamalla oppijankielen sujuvuutta, tarkkuutta ja kompleksisuutta. Kompleksisuus voidaan määritellä oppijankielen monipuolisuudeksi ja kehittyneisyydeksi, mutta syntaktista kompleksisuutta on kansainvälisessä toisen kielen oppimisen tutkimuksessa tyypillisesti mitattu alisteisiin lauserakenteisiin perustuvilla kvantitatiivisilla mittareilla. Tässä artikkelissa syntaktisen kompleksisuuden kehitystä tutkitaan tarkastelemalla rinnastus- ja alistuskonjunktioiden käyttöä suomi toisena kielenä -teksteissä Eurooppalaisen viitekehyksen eri taitotasoilla. Aineistona käytetään Jyväskylän yliopiston Cefling-hankkeen oppijansuomen korpuksen tekstejä. Rinnasteis…
Anonymization as homeomorphic data space transformation for privacy-preserving deep learning
2021
Industry 4.0 is largely data-driven nowadays. Owners of the data, on the one hand, want to get added value from the data by using remote artificial intelligence tools as services, on the other hand, they concern on privacy of their data within external premises. Ideal solution for this challenge would be such anonymization of the data, which makes the data safe in remote servers and, at the same time, leaves the opportunity for the machine learning algorithms to capture useful patterns from the data. In this paper, we take the problem of supervised machine learning with deep feedforward neural nets and provide an anonymization algorithm (based on the homeomorphic data space transformation),…
Konfigurowanie granic gatunkowych a problem polityczności. Przypadek posthumanizmu i transhumanizmu
2017
Przedmiotem artykułu są teoriopolityczne rozważania na temat posthumanizmu. Jest to podejście, które zrywa z humanistycznym dogmatem, że człowiek jest bytem najważniejszym w rzeczywistości. Zamiast tego posthumanizm dowartościowuje byty pozaludzkie (naturalne, sztuczne, rzeczy), z którymi ludzie wchodzą w rozmaite interakcje. Autor uznał, że problematyka posthumanistyczna może być rozpatrywana w perspektywie biopolityki, która zajmuje się relacjami między polityką a życiem. Jednakże w odróżnieniu od wcześniejszych ujęć wiążących biopolitykę z kontrolą populacji posthumanizm stawia na szali żywotność gatunkową. W artykule przedstawiono konsekwencje takiego myślenia dla problemu polityczności…
Three-dimensional core-collapse supernovae with complex magnetic structures: I. Explosion dynamics
2021
Magnetic fields can play a major role in the dynamics of outstanding explosions associated to violent events such as GRBs and hypernovae, since they provide a natural mechanism to harness the rotational energy of the central proto-neutron star and power relativistic jets through the stellar progenitor. As the structure of such fields is quite uncertain, most numerical models of MHD-driven core-collapse supernovae consider an aligned dipole as initial magnetic field, while the field's morphology can actually be much more complex. We present three-dimensional simulations of core-collapse supernovae with more realistic magnetic structures, such as quadrupolar fields and, for the first time, an…
The impact of non-dipolar magnetic fields in core-collapse supernovae
2019
The magnetic field is believed to play an important role in at least some core-collapse supernovae if its magnitude reaches $10^{15}\,\rm{G}$, which is a typical value for a magnetar. In the presence of fast rotation, such a strong magnetic field can drive powerful jet-like explosions if it has the large-scale coherence of a dipole. The topology of the magnetic field is, however, probably much more complex with strong multipolar and small-scale components and the consequences for the explosion are so far unclear. We investigate the effects of the magnetic field topology on the dynamics of core-collapse supernovae and the properties of forming proto-neutron star (PNS) by comparing pre-collap…
Social accounting and its contribution to society
2013
With the development of the society and its economic system, a need has emerged to develop accounting as well. The increasing role of social accounting, which keeps records of for-profit, non-profit, and governmental organisations, is associated with the complexity of the environment in which businesses and organisations are operating and presenting reports about their social, ethical, and environmental aspects. Organisations are subject to greater transparency, and many stakeholders are interested in and concerned about the performance of organisations within the context that is not reflected, to a satisfactory extent, in traditional accounting. Traditional accounting ensures reporting to …
