Irregular Migrants or Illegal Migrants?: The Canadian News Media’s Representation of Haitian Asylum Seekers In the Imagined NationJoseph, Robynn S. 04 September 2020 (has links)
In Spring/Summer 2017 there was an increase in Haitian nationals from the United States, entering Canada, reaching numbers as high of 7,787 (Government of Canada, 2019). This increase in irregular migration was covered by various news outlets and Canadian government officials addressed this as a ‘problem’. Given this important media and political reality, this thesis sought to explore the media representation of Haitian irregular migration. More specifically, I examine the media’s depiction of Haitian asylum seekers as well as the nation. Therefore, the goal of this thesis is to contextualize this media representation within a wider socio-political context.
Through a Critical Race Theory perspective, I conduct a qualitative content analysis of news media articles published in the Toronto Star and The Globe and Mail. The analysis reveals that the nation is imagined as innocent while the asylum seekers are constructed as threats. This thesis goes on to demonstrate how the media has relied on a discourse of inclusion/exclusion and of victimization in order to positively imagine the nation. Meanwhile, by framing asylum seekers’ motivations for entering Canada as frivolous and by utilizing techniques of vilification, the media is able to delegitimize the asylum seekers’ claims. Finally, this thesis concludes that the media has a tendency to omit the socio-political context of its portrayal of the asylum seekers and of the nation. Therefore, it is important for the media to accurately represent irregular migration in order to expose global inequalities.

The impact of jamming on boundaries of collectively moving weak-interacting cellsNnetu, Kenechukwu David, Knorr, Melanie, Käs, Josef, Zink, Mareike 16 August 2022 (has links)
Collective cell migration is an important feature of wound healing,
as well as embryonic and tumor development. The origin of collective cell
migration is mainly intercellular interactions through effects such as a line
tension preventing cells from detaching from the boundary. In contrast, in this
study, we show for the first time that the formation of a constant cell front of a
monolayer can also be maintained by the dynamics of the underlying migrating
single cells. Ballistic motion enables the maintenance of the integrity of the
sheet, while a slowed down dynamics and glass-like behavior cause jamming of
cells at the front when two monolayers—even of the same cell type—meet. By
employing a velocity autocorrelation function to investigate the cell dynamics
in detail, we found a compressed exponential decay as described by the
Kohlrausch–William–Watts function of the form C(δx)t ∼ exp (−(x/x0(t))β(t)),
with 1.5 6 β(t) 6 1.8. This clearly shows that although migrating cells are an
active, non-equilibrium system, the cell monolayer behaves in a glass-like way,
which requires jamming as a part of intercellular interactions. Since it is the
dynamics which determine the integrity of the cell sheet and its front for weakly
interacting cells, it becomes evident why changes of the migratory behavior
during epithelial to mesenchymal transition can result in the escape of single
cells and metastasis.

POPULATION REGULATION IN BLUEGILLS (LEPOMIS MACROCHIRUS).BIANCHI, EDWARD WILLIAM, JR. January 1984 (has links)
Residency or emigratory responses were triggered in bluegills 6.0-8.0 cm TL and 10.0-12.0 cm TL by availability of resources. Individuals became residents if resources were present and not at carrying capacity. Individuals in excess of carrying capacity emigrated. Carrying capacity of bluegills 6.0-8.0 cm TL increased with increased food availability. Carrying capacity also increased with increased cover. Bluegills 10.0-12.0 cm TL did not respond to changes in cover. The two sizes reacted differently when the initial number introduced into pools was varied. Single bluegills 6.0-8.0 cm TL established residency whereas bluegills 10.0-12.0 cm TL required the presence of at least one other bluegill before establishing residency. Competition between size classes were prevented by habitat segregation in which smaller fish used areas with cover and larger fish areas of open water. These results indicate that bluegills have evolved innate, stereotypic fixed action patterns for individually assessing resources by becoming residents if resources are present and numbers below carrying capacity or emigrating if resources are absent or numbers at carrying capacity. These findings suggest that the long history of overpopulation and stunting of bluegills in closed areas is due to the absence of an emigratory avenue.
