Transnational Social Fields
2018
This chapter excavates Bourdieu’s theoretical insights concerning political sociology to develop a theory of transnational structuration processes. The early Bourdieu implicitly imagined the state as a nationally bounded actor. Only later in his career did he begin to grapple with issues such as globalization, transnationalism, and neoliberalism; and it is this later germ of ideas that this chapter develops. Transnational social fields, this chapter argues, are not reducible to institutional or organizational structures. They require a more holistic analysis of institutions and their underpinnings. To provide an example of how Bourdieu’s political sociology can be extended to transnational …
Análisis del proceso migratorio de las familias colombianas en España
2014
espanolSe analiza la migracion como proceso centrado en la familia transnacional, segun relato de sus protagonistas: migrantes - padres e hijos - y familiares en Colombia. Se parte del modelo sistemico y de la metodologia de la Grounded-Theory. El proceso se desencadena por una combinacion de factores de empuje y de llamada; los pioneros, mayoritariamente mujeres, poseen un perfil muy variado. Destaca la dificultad de sus primeras experiencias, que mejoran gracias a sus apoyos externos y a su teson. A pesar de las dificultades del proceso de aculturacion, el balance realizado es positivo, sobre todo por la esperanza puesta en los hijos, que tras las dificultades iniciales desean permanecer …
Un'applicazione della Social Network Analisys alla rete di relazioni di un Gruppo d’Acquisto Solidale: l’esperienza di Gasualmente
2012
The phenomenon of GAS (Solidarity Purchase Groups) in Sicily has in Gasualmente an important actor. This GAS, was created following a structured training program and research by the Faculty of Agriculture of the University of Palermo. It now plays an important role as activator of relationships and ethical affirmation of critical consumption, and promotion of organic products. The study aims through the Social Network Analysis, to investigate Gasualmente network and the role played by all the actors involved.
Land Snails as a Valuable Source of Fatty Acids: A Multivariate Statistical Approach
2019
The fatty acid (FA) profile of wild Theba pisana, Cornu aspersum, and Eobania vermiculata land snail samples, collected in Sicily (Southern Italy), before and after heat treatment at +100 °C were examined by gas chromatography with a flame ionization detector (GC-FID). The results show a higher content of polyunsaturated fatty acids (PUFAs) in all of the examined raw snails samples, representing up to 48.10% of the total fatty acids contents, followed by monounsaturated fatty acids (MUFAs). The thermal processing of the snail samples examined determined an overall reduction of PUFA levels (8.13%, 7.75%, and 4.62% for T. pisana, C. aspersum and E. vermiculata samples, respectively) and a spe…
Metallothionein in the freshwater gastropod Melanopsis dufouri chronically exposed to cadmium: A methodological approach
2010
Previous studies have demonstrated that the use of differential pulse polarography (DPP) for metallothionein (MT) determination in marine gastropod tissues, particularly the digestive gland, requires taking into account the presence of heat-stable high molecular weight compounds that exhibit polarographic signal. In the present paper, similar compounds were identified in tissues from the freshwater snail Melanopsis dufouri which also interfere with MT determination by DPP and, due to their silver binding capacity, also interfere in the silver assay for MT quantification. Ultrafiltration seems to be effective in removing these high molecular weight compounds from heat-denatured homogenate su…
Effect of Stem Snapping on Aspen Timber Assortment Recovery in Hemiboreal Forests
2020
Post-disturbance salvage logging mitigates economic loss after windthrow, and the value of salvaged timber is strongly linked to its quality and dimensions. We studied the occurrence of wind-induced damage of aspen in the hemiboreal forests of Latvia based on data from the National Forest Inventory and additional measurements. Individual tree data from three re-measurement periods were linked to follow a tree condition (live, broken, uprooted) and to link tree characteristics to a respective snag. Three linear models were developed to assess factors affecting the snapping height. An assortment outcome was calculated for undamaged and salvaged trees using the bucking algorithm, and timber va…
THE EFFECTS OF MATING SYSTEM AND GENETIC VARIABILITY ON SUSCEPTIBILITY TO TREMATODE PARASITES IN A FRESHWATER SNAIL, LYMNAEA STAGNALIS
2004
The amount and distribution of genetic variability in host populations can have significant effects on the outcome of host-parasite interactions. We studied the effect of mating system and genetic variability on susceptibility of Lymnaea stagnalis snails to trematode parasites. Mating system of snails from eight populations differing in the amount of genetic variability was manipulated, and self- and cross-fertilized offspring were exposed to naturally occurring trematode parasites in a controlled lake experiment. Susceptibility of snails varied between populations, but mating-system treatment did not have a significant effect. Heterozygosity of snails was negatively correlated with the pro…
Academic capitalism and the informational fraction of the transnational capitalist class
2013
This article is based on the idea that if we are witnessing an on-going shift towards the transnational phase of capitalism, this objective structural change should also be taken into account in higher education studies. In this sense, this article reflects the increased scholarly attention into the relationship between globalisation and higher education since the 1990s. The main purpose of this article is to contribute to these discussions by developing dialogue between global capitalism theories and the theory of academic capitalism. In order to achieve this, William Robinson's concept of the transnational capitalist class (TCC) will be amended to include also the informational fraction. …
Terminological Games: The Finnish Security Police Monitoring the Far-Right Movements in Finland During the Cold War
2020
This article focuses on the use of terms and concepts related to the nationalist movements by the Finnish security police during the Cold War. The key objective of the security police was to protect the legal order of the state and monitor the groups and phenomena potentially harmful to that cause. The previous experience regarding the rise of the radical nationalism and fascism in Finland in the 1930s and the 1947 Paris peace treaties were the historical and legal contexts within which the interpretations were made. As the article shows, interpretation made by the security police, however, relied occasionally on a limited understanding about the evolving far-right scene, thus producing ter…
Integrating a Nexus: the history of political discourse and language policy research
2019
Historians of political discourse and language policy researchers should join forces to develop methods of textual analysis that help to integrate political and intellectual history. They could do so by focusing their analysis on interconnections between material realities, human physical action, practices and structures, as well as institutions and ideologies as discursive constructs. Such a version of soft constructivism underscoring the discursive nature of much of politics encourages historians to analyse past political discourses more systematically. Concepts such as nexus, historical body, mobility and discursive transfers borrowed from language research deepen our analytical understa…
