Ontology and Reason Giving in Law [PDF]

open access: yes, 2016
John Gardner has noted that legal positivism is more a theory of legal validity than it is a theory about law ’ s nature. 1 This is true in that one can be a legal positivist and hold a variety of different theories about law ’ s nature, but not to the

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Codon insertion and deletion functions as a somatic diversification mechanism in human antibody repertoires

open access: yesBiology Direct, 2006
It has been suggested that codon insertion and/or deletion may represent a mechanism that, along with hypermutation, contributes to the affinity maturation of antibodies.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

A Defence of a Rationalist Conception of Practical Reason

open access: yesEuropean Journal of Analytic Philosophy, 2017
In this paper I attempt to refute the instrumental conception of practical reason, and thus defend a rationalist conception of practical reason. I argue that, far from merely playing an instrumental role, reason can be used by an agent to evaluate, that ...

Sufficient Reason and Reason Enough [PDF]

open access: yesFoundations of Science, 2015
I offer an analysis of the Principle of Sufficient Reason and its relevancy for the scientific endeavour. I submit that the world is not, and cannot be, rational - only some brained beings are. The Principle of Sufficient Reason is not a necessary truth nor a physical law.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Epistemic Democracy and the Truth Connection [PDF]

open access: yesPublic Reason
If political decision-making aims at getting a particular result, like identifying just laws or policies that promote the common good, then political institutions can also be evaluated in terms of how often they achieve these results.

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...
