Onset of convection in a porous rectangular channel with external heat transfer to upper and lower fluid environments

2012

Published version of an article in the journal: Transport in Porous Media. Also available from the publisher at: http://dx.doi.org/10.1007/s11242-012-0018-9 The conditions for the onset of convection in a horizontal rectangular channel filled with a fluid saturated porous medium are studied. The vertical sidewalls are assumed to be impermeable and adiabatic. The horizontal upper and lower boundary walls are considered as impermeable and subject to external heat transfer, modelled through a third-kind boundary condition on the temperature field. The external fluid environments above and below the channel, kept at different temperatures, provide the heating-from-below mechanism which may lead…

El principio de buena administración y la gobernanza en la contratación pública

2020

Las exigencias de la sociedad sobre la administración pública pasan por profundizar en el comportamiento y en la dedicación profesional, sobre todo, de los administradores y gestores públicos. Todo ello no es más que trasunto del principio de buena administración que, como ya he destacado, es hoy un derecho de los ciudadanos, que reclama mayor objetividad en la toma de decisiones, mayor intensidad en la defensa de los derechos de los ciudadanos, más transparencia, más control y, sobre todo una más proactiva rendición de cuentas. Se trata, en definitiva, de imbuir a los gestores públicos y a los ciudadanos que más frecuente y estrechamente se relacionan con ellos, de sentimientos de ética, d…

Establishing Video Game Genres Using Data-Driven Modeling and Product Databases

2015

Establishing genres is the first step toward analyzing games and how the genre landscape evolves over the years. We use data-driven modeling that distils genres from textual descriptions of a large collection of games. We analyze the evolution of game genres from 1979 till 2010. Our results indicate that until 1990, there have been many genres competing for dominance, but thereafter sport-racing, strategy, and action have become the most prevalent genres. Moreover, we find that games vary to a great extent as to whether they belong mostly to one genre or to a combination of several genres. We also compare the results of our data-driven model with two product databases, Metacritic and Mobyga…

Live free or die motionless : Walking the migrant path from Italy to France

2018

This essay and the photographs examine visual traces of irregular mobility in the border landscape between Italy and France. The ruined buildings and objects witness decades of movement of undocumented people on this old migrant path across the mountains. By taking the theoretical concept of multidirectional memory (Rothberg 2009) the essay argues that the Path of Hope can be thought of as a memory site through which the issues of migration in contemporary Europe can be seen in a more sustainable light. The ruins and discarded objects link memories of different places – including different border zones – in ways that allow us to critically examine borders as a practice – rather than as exis…

School performance of children from monogamous and polygamous families in Nigeria

2014

Scholastic success of Nigerian children coming from polygamous ( n = 50) and monogamous families ( n = 156) was compared. No differences between the two groups were observed across background variables of demographics, parental education and occupation, or family support for schooling. There were no differences in the Junior Secondary School Entrance Exam scores between the groups. However, children from polygamous families reported more difficulties in mathematics and English than their counterparts from monogamous families. The findings are discussed in relation to previous research.

Temporality in cosmopolitan solidarity : Archival activism and participatory documentary film as mediated witnessing of suffering at Europe’s borders

2019

This article develops and extends the idea of cosmopolitan solidarity to temporality through a case study of archival activism and participatory film-making. It examines mediated witnessing within the Italian online audiovisual archive Archivio delle memorie migranti, which documents and archives the experiences of contemporary migrants in Italy. The moral basis of Archivio delle memorie migranti is cosmopolitan solidarity, which is usually understood as a practice that crosses spatial and communal boundaries. However, the ethics of solidarity also bridges past, present and future generations. Through the case of Archivio delle memorie migranti, this article demonstrates the significance o…

Global and local interactions in football : the changing field of professional football stadiums in Finland and Hungary in the 2000s

2018

This article aims to increase understanding of the global-local contexts in football by exploring the changing field of professional football stadiums in Finland and Hungary in the 2000s. More specifically, the cases of two clubs, HJK (Finland) and Ferencvárosi TC (Hungary) are studied. We employ concepts of sport and globalization. The research data consist of semi-structured expert interviews with Finnish and Hungarian football practitioners, media and club documents, and data from observation. The results suggest that interactions of global and local forces are reflected in the development and operation of stadiums. On the one hand, international and national governing bodies have streng…

Death and Transfiguration : The Late Kim Jong-il Aesthetic in North Korean Cultural Production

2016

This article assesses the official music scene in Pyongyang over a span of five dramatic years, surveying how changes in the field of music from 2009 to 2014 mirrored and in some cases presaged North Korean dynastic succession and political consolidation. The article draws upon a new abundance of performance data on North Korean musical groups, data which we argue is important but has largely been ignored or mischaracterized heretofore. The central crisis dealt with in the article is the decline and demise of Kim Jong-il, the architect of North Korea’s musical culture. In his final years, Kim Jong-il assented to the creation of a new leading musical group known as the Unhasu Orchestra, prom…
