Preliminary Design of a Laboratory Cylindrical Hall-Effect Thruster
, 2012 A 3-cm cylindrical Hall thruster with permanent magnets was designed and modeled. The goal was to design a Hall thruster for Cal Poly’s propulsion laboratory of similar size and performance as Cal Poly’s MiXI thruster.

Plume Reduction in Segmented Electrode Hall Thruster [PDF]
, 2000 A segmented electrode, which is placed at the thruster exit, is shown to affect thruster operation in several ways, whether the electrode produces low emission current or no emission current, although there appear to be advantages to the more emissive ...

Toward Comprehensive Climate Action: Assessing Mitigation Approaches Across Canadian Municipalities
Environmental Policy and Governance, EarlyView.ABSTRACT Local governments are widely regarded as key leaders in the global response to climate change. Understanding if and how municipalities commit to climate mitigation is crucial for assessing their contribution to global emission‐reduction goals and identifying barriers to effective climate transitions.

Environmental Policy and Governance, EarlyView.ABSTRACT Since the 1990s, environmental policy has shifted toward ecosystem protection and biodiversity conservation, a development often described as an ecological turn. This article argues that in practice this turn has taken the form of an ecological “U‐turn,” as environmental ambitions are subordinated to production‐oriented objectives.

European Journal of Social Psychology, EarlyView.ABSTRACT Societal gender role norms play a crucial role in shaping men's and women's career aspirations. However, prior research documenting this key role of gendered norms has primarily focused on heterosexual women and men in the global North‐West. Previous studies documenting differences in career interests by sexual orientation suggest that gender ...

European Policy Analysis, EarlyView.ABSTRACT Policy process research has excelled in explaining structural policy change within national settings, but extensions and applications to the EU level have long proven challenging for scholars. Given that the EU is currently experiencing its longest period of Treaty stability since the 1980s—having evolved into a sui generis political system ...
