Assessing The Influence Of Behavioural Parameterisation On The Dispersal Of Larvae In Marine Systems, M. K. James, J. A. Polton, C. G. Mayorga-Adame, K. L. Howell, A. M. Knights

School of Biological and Marine Sciences

Predicting dispersal and quantifying ecological connectivity are increasingly referenced as fundamental to understanding how biodiversity is structured across space and time. Dispersal models can provide insight, but their predictions are influenced by our capacity to simulate the biology and physics known to influence dispersal. In a marine context, vertical swimming behaviour is considered important in influencing the spatial organisation of species across seascapes, but the mechanisms underpinning these movements remain unresolved, making it unclear how best to incorporate behaviour within models. Here, using a 3-D hydrodynamic model coupled with a Lagrangian particle tracker, we show how different modelled larval behaviours, …

From Protection To Prevention: The Case For Incorporating Anti-Sexual Harassment Provisions Into Nova Scotia’S Occupational Health And Safety Legislation, Sydney Hull

Dalhousie Journal of Legal Studies

This paper asks if the law in Nova Scotia adequately reflects the accepted notion that every employee has the right to a workplace free from sexual harassment. Nova Scotia trails most other Canadian jurisdictions in its exclusion of psychological violence and mental health hazards from occupational health and safety legislation. This paper begins by canvassing current legal remedies available to victims of workplace sexual harassment. Concluding that current human rights, tort, and contact frameworks do not sufficiently protect employees, it argues that Nova Scotia’s Occupational Health and Safety Act must be amended to include sexual harassment and other forms of …
