A Reappraisal of the Expulsion of Illegal Immigrants from Nigeria in 1983 [PDF]

open access: yesInternational Journal of Conflict and Violence, 2016
In recent years, Nigeria has been quietly expelling more and more immigrants from Niger, Mali, Chad and Cameroon. These foreigners – migrant workers or small traders – face the reinforcement of migration control and the blind fight of the government ...

A “coup d’État” in Jersey?

open access: yesDiasporas: Circulations, Migrations, Histoire, 2019
In late 1855, thirty-nine European refugees were summarily expelled from the island of Jersey, a crown dependency of the United Kingdom. The only explicitly political deportations of foreign nationals from the British Isles in the Victorian era, these ...

A Change in the Frame: From Absenteeism to Attendance

open access: yesFrontiers in Education, 2020
School attendance is important for student long-term academic and career success. However, in the U.S., our current practice often disenfranchises more at-risk students than it helps.

The mass function and dynamical mass of young star clusters: Why their initial crossing-time matters crucially

open access: yes, 2012
We highlight the impact of cluster-mass-dependent evolutionary rates upon the evolution of the cluster mass function during violent relaxation, that is, while clusters dynamically respond to the expulsion of their residual star-forming gas.

The star cluster survivability after gas expulsion is independent of the impact of the Galactic tidal field [PDF]

open access: yes, 2019
We study the impact of the tidal field on the survivability of star clusters following instantaneous gas expulsion. Our model clusters are formed with a centrally-peaked star-formation efficiency profile as a result of star-formation taking place with a ...

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control

open access: yesAdvanced Engineering Materials, EarlyView.
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

Researching the city and walking with street dwellers: Recreating urban encounters past and present

open access: yesCoolabah, 2017
The art of recreating cities imaginatively and the critical act of reading urban fiction involve processes of research and learning that often include encounters with specific cities and their dwellers, prompting reflection on the forms and ethics of ...

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

open access: yesAdvanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Acceptance rate, probability of follow-up, and expulsion of postpartum intrauterine contraceptive device offered at two primary health centers, North India

open access: yesJournal of Family Medicine and Primary Care, 2016
Introduction: Acceptance rate of postpartum intrauterine contraceptive device (PPIUCD) offered through a public health approach is unknown. Our aim was to describe the acceptance rate, expulsion, and follow-up and factors associated with it when PPIUCD ...
