Wyzwania latynoamerykańskiej migracji jako zagrożenie dla bezpieczeństwa społecznego w zachodniej hemisferze
2017
W artykule autor przedstawia zróżnicowane spojrzenie na problem migracji: emigrację z krajów latynoamerykańskich i imigrancką perspektywę w Stanach Zjednoczonych. Problem ujmuje przede wszystkim jako wyzwanie i jednocześnie zagrożenie dla bezpieczeństwa społecznego, ze względu na współwystępujące problemy: nierówności społeczne, ubóstwo, wyzysk w miejscu pracy. Temat w dalszym ciągu jest aktualny, również ze względu na jego polityczne uwarunkowania, obecne w kampanii wyborczej w 2016 roku w Stanach Zjednoczonych.
Przemoc, narkotyki i bezpieczeństwo publiczne jako wyzwanie dla świata polityki w wieku XXI na przykładzie wybranych państw Ameryki Łacińskiej
2016
W artykule przeanalizowano kluczowe problemy bezpieczeństwa publicznego w wybranych państwach Ameryki Łacińskiej, który to region bywa postrzegany jako przestrzeń szczególnie narażona na wyzwania stojące przed elitami politycznymi próbującymi radzić sobie z wyzwaniami współczesnego świata, w optyce społecznej, gospodarczej i politycznej. Zwrócono szczególną uwagę na kwestie dotyczące intensyfikacji przemocy związanej z nierozwiązanym od kilku dekad problemem produkcji i eksportu narkotyków.
Leader election and local identifiers for three‐dimensional programmable matter
2020
International audience; In this paper, we present two deterministic leader election algorithms for programmable matter on the face-centered cubic grid. The face-centered cubic grid is a 3-dimensional 12-regular infinite grid that represents an optimal way to pack spheres (i.e., spherical particles or modules in the context of the programmable matter) in the 3-dimensional space. While the first leader election algorithm requires a strong hypothesis about the initial configuration of the particles and no hypothesis on the system configurations that the particles are forming, the second one requires fewer hypothesis about the initial configuration of the particles but does not work for all pos…
A nested virtualization tool for information technology practical education
2016
Background A common problem of some information technology courses is the difficulty of providing practical exercises. Although different approaches have been followed to solve this problem, it is still an open issue, specially in security and computer network courses. Results This paper proposes NETinVM, a tool based on nested virtualization that includes a fully functional lab, comprising several computers and networks, in a single virtual machine. It also analyzes and evaluates how it has been used in different teaching environments. Conclusions The results show that this tool makes it possible to perform demos, labs and practical exercises, greatly appreciated by the students, that woul…
A status report
1992
Abstract This article considers the financial and proprietary considerations applicable to computer crime, computer security and personal privacy. The failure to take proper precautions in these areas can lead to major operational problems and substantial loss of assets. Developments in the late 1980s, particulary the discovery by the public press of so-called ‘computer viruses’, indicates the need for counsel representing suppliers and users to understand the basic technology involved and the legal implications. Such a report by Robert Bigelow was first published in CLSR in March 1989. He has now updated and revised the text which will be featured in several parts. In the first parts the l…
Early assessment of crop yield from remotely sensed water stress and solar radiation data
2018
Soil moisture (SM) available for evapotranspiration is crucial for food security, given the significant interannual yield variability of rainfed crops in large agricultural regions. Also, incoming solar radiation (Rs) influences the photosynthetic rate of vegetated surfaces and can affect productivity. The aim of this work is to evaluate the ability of crop water stress and Rs remotely sensed data to forecast yield at regional scale. Temperature Vegetation Dryness Index (TVDI) was computed as an indicator of crop water stress and soil moisture availability. TVDI during critical growth stage of crops was calculated from MODIS products: MODIS/AQUA 8-day composite LST at 1 km and 16-day compos…
Precipitation responses to ENSO and IOD in the Maldives: Implications of large-scale modes of climate variability in weather-related preparedness
2020
Abstract This research seeks to address the extent to which indices of large-scale modes of climate variability (El Nino Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD)) can be linked to physical differences in the local mean and extreme rainfall conditions experienced in the Maldives in order to suggest implications for disaster risk reduction (DRR). While some significant differences in precipitation metrics do occur at the local level between different phases of the large-scale modes of climate variability studied, they do not occur for all sites studied. While the constrained availability of historical meteorological data in the region is a limiting factor in this analysis, th…
CSCL – a tool to motivate foreign language learners: The Finnish application
2003
This article discusses the applications of the theory of Computer Supported Collaborative Learning (CSCL) to teaching and learning a foreign language, in this case, one of the ‘Less Commonly Taught Languages’, Finnish. The ‘Virtually Finnish’ project was based on the idea of creating a larger, virtual Finnish learning community among the second-year Finnish language students in five US universities during the fall semester, 2001. CSCL was chosen as a base, as its principal goal is to aid the learners in sharing and distributing their knowledge to the whole learning community. In addition to discussing the set up and the content of the project, the students’ feedback about their language lea…
Negotiating digital surveillance legislation in post-Snowden times : An argumentation analysis of Finnish political discourse
2019
Abstract In the digital era, when security agencies world-wide have been challenging basic democratic principles with massive data gathering, Finland has had a different approach: it has conducted no large-scale surveillance of citizens’ online activities. Now, however, the country is planning such a vast expansion of state surveillance that the constitution itself must be altered. The present article examines one key point in this legislative process to see how the new surveillance measures are argued for and criticized, and how the differing points of view are negotiated to ultimately enable political action. Drawing particularly on Fairclough and Fairclough’s (2012) approach to argumenta…
Translation and didactics in the language classroom: the preparation and dissemination of a dual-language critical edition of José Luis Alonso de San…
2015
We have clearly come a long way from the time when translation’s principal role in the classroom was as a tool for language acquisition. This has been a positive development in many respects but, as we hope to demonstrate, the insights gleaned from this specific case-study – viewed through the prism of a Foucauldian approach to the archaeology of the disciplines – illustrate the need for a more general reassessment of the educational and scholarly potential of the dual-language text, a once-popular and well-respected literary and pedagogical resource which was the collateral victim of the disciplinary warfare by which translation and language education were able to establish themselves as a…
