Evidence for the Effects of Space Weathering Spectral Signatures on Low Albedo Asteroids

open access: yes, 2013
Context. Space weathering changes asteroid surfaces. We know from observations of the Moon and high-albedo asteroids that interplanetary surface processes can alter the spectral properties of silicates.

Asteroids and comets

open access: yesEos, Transactions American Geophysical Union, 1971
Review Articles and Meetings. I will concentrate on recent review articles, especially when they give titles of earlier papers. Only for asteroids, because there seems to be no published review, and for other selected topics will we go back more than 4 years.

Rational Slack and Doxastic Grain

open access: yesPacific Philosophical Quarterly, EarlyView.
ABSTRACT This paper argues for granular permissivism, roughly the view that evidence is sometimes permissive between doxastic attitudes at different levels of grain. The argument identifies three sources of rational slack between granularly differing doxastic states: doxastic tidiness, safety, and evidential responsiveness.

Categorial versus naturalized epistemology

open access: yesAnalytic Philosophy, EarlyView.
Abstract How do we know what kinds of things constitute knowledge or justified belief? Naturalized epistemology is committed to denying a priori insight into the kinds of kinds that are and are not knowledge or justification makers. By contrast, it is argued here that knowledge of these matters is a priori knowledge of a special kind.

Social beneficence

open access: yesPhilosophy and Phenomenological Research, EarlyView.
Abstract A background assumption in much contemporary political philosophy is that justice is the first virtue of social institutions, taking priority over other values such as beneficence. This assumption is typically treated as a methodological starting point, rather than as following from any particular moral or political theory.

Meteorite spectroscopy and characterization of asteroid surface materials [PDF]

open access: yes
The analysis of visible and near-infrared reflectance spectra is the primary means to determine surface mineralogy and petrology of individual asteroids.

Managing and mitigating future public health risks: Planetary boundaries, global catastrophic risk, and inclusive wealth

open access: yesRisk Analysis, EarlyView.
Abstract There are two separate conceptualizations for assessing existential risks: Planetary Boundaries (PBs) and global catastrophic risks (GCRs). While these concepts are similar in principle, their underpinning literatures tend not to engage with each other.

A framework for evolving assumptions in risk analysis

open access: yesRisk Analysis, EarlyView.
Abstract Risk assessment can be used to evaluate the risks of complex systems and emerging technologies, such as the human–climate nexus and automation technologies, and to inform pathways and policies. Due to the interconnected and evolutionary features of such topics, risk analysts must navigate the dynamics of changing assumptions and probabilities ...

Before it's too late: The extinction script, multi‐species reproductive futurism and Extinction Rebellion

open access: yesTransactions of the Institute of British Geographers, EarlyView.
Short Abstract The belief that we have to act now to avoid a future lost knowingly to self‐inflicted extinction operates through what I term ‘the extinction script’. As a technology of power that regulates climate futures, the extinction script implores the already threatened subject to act now and to do so urgently.
