Affective (re)orientations in online discussions on the threat of violence posed by migrants

2020

Online discussions are rife with fear-evoking images and meaning making that highlight a perceived threat to the security of European nations and their inhabitants posed by migrants’ violence in the wake of increased immigration. This paper examines the role of emotions in shaping anti-immigration views as a response to the threat of violence attached to migrants in online conversations. Using a dataset of Finnish online discussion threads from 2015 to 2017 that were prompted by extensive media attention paid to various cases of violent crime in which migrants were suspects, we particularly analyse the affective dynamics of interpellation processes wherein discussants are invited to adopt a…

When Affective (But Not Cognitive) Ambivalence Predicts Discrimination Toward a Minority Group

2013

Individuals often hold ambivalent attitudes (i.e., positive and negative attitudes at the same time) toward groups and social categories. The aim of the present research was to examine the differential effects of affective and cognitive dimensions of ambivalence on the (amplification of) responses towards a minority group. We asked 188 students from the University of Perugia to read a short description of a fictitious group of immigrants. After expressing their affective and cognitive attitudes toward the target group, participants received positive, negative, or no supplementary information about this group. Discrimination was assessed by asking participants to allocate to the target group…

Essential? COVID-19 and highly educated Africans in Finland’s segmented labour market

2022

PurposeThe purpose of this paper is to characterise the position of highly educated African migrants in the Finnish labour market and to examine the impact of the COVID-19 pandemic on that position.Design/methodology/approachThe paper is based on the biographical work stories of 17 highly educated African migrant workers in four occupation areas in Finland: healthcare, cleaning, restaurant and transport. The sample was partly purposively and partly theoretically determined. The authors used content driven thematic analysis technique, combined with by the biographical narrative concept of turning points.FindingsUsing the case of highly educated African migrants in the Finnish labour market, …

A Generic Agent-Based Model of Historical Social Behaviors Change

2016

The primary theme of this chapter is trying to describe, discuss and understand how human societies change over time using agent-based modeling. Agents become a major paradigm of social simulation allow us to model the complex social phenomena under the bottom-up approach. Certainly one of the key points of the bottom-up approach is the emergence of macro level phenomena from micro level actions and interactions. The main objective of this work is to build a Virtual Social Laboratory, from Rafael Pla Lopez Social evolution model, in order to explore the social evolution of a set of artificial societies/agents that evolve within a grid of cells which are characterized by a level of natural r…

Age-dependent inbreeding risk and offspring fitness costs in female black grouse

2011

Dispersal is an important mechanism used to avoid inbreeding. However, dispersal may only be effective for part of an individual's lifespan since, post-dispersal individuals that breed over multiple reproductive events may risk mating with kin of the philopatric sex as they age. We tested this hypothesis in black grouse Tetrao tetrix , and show that yearling females never mated with close relatives whereas older females did. However, matings were not with direct kin suggesting that short-distance dispersal to sites containing kin and subsequent overlap of reproductive lifespans between males and females were causing this pattern. Chick mass was lower when kinship was high, suggesting impor…

The aged brain: Genesis and fate of residual progenitor cells in the subventricular zone

2015

Neural stem cells (NSCs) persist in the adult mammalian brain through life. The subventricular zone (SVZ) is the largest source of stem cells in the nervous system, and continuously generates new neuronal and glial cells involved in brain regeneration. During aging, the germinal potential of the SVZ suffers a widespread decline, but the causes of this turn down are not fully understood. This review provides a compilation of the current knowledge about the age-related changes in the NSC population, as well as the fate of the newly generated cells in the aged brain. It is known that the neurogenic capacity is clearly disrupted during aging, while the production of oligodendroglial cells is no…

Les dynamiques du périurbain dijonnais entre 1990 et 1999

2009

Un étalement urbain accompagne désormais la croissance des villes, notamment les plus grandes. Principalement expliqué par un desserrement résidentiel, il est aussi la résultante des dynamiques de centralisation de l’emploi et de spécialisation des zones d’activité à l’intérieur des aires urbaines. L’exemple dijonnais met bien en lumière ce double mouvement qui affecte les communes de sa périphérie et contribue à accroître les mobilités. Urban sprawl arises from the growth of cities, especially of the biggest cities. This urban sprawl is accounted for mainly by residential clearing. It results also from the dynamics of centralization of employment and from specialization of activity zones i…

The Coexistence of Three Species of Daphnia in the Klostersee: iii. The Simulation Model Coda

1991

The population dynamics of three coexisting Daphnia species are described by means of a discrete event simulation model. The model is formulated in the algorithmic language SIMULA which allows very convenient object-oriented programming. Different compartments of a lake are simulated at different levels of integration, each represented by a PROCESS CLASS in SIMULA: The properties of the lake are deposited in a set of meteorological data which were measured in the field. Fish are simulated as a population with properties which are derived from field observations and Daphnia are represented as individuals. The model shows that hypotheses about the stabilizing mechanisms (seasonal change of en…
