Maurinian Truths : Essays in Honour of Anna-Sofia Maurin on her 50th Birthday
This book is in honour of Professor Anna-Sofia Maurin on her 50th birthday. It consists of eighteen essays on metaphysical issues written by Swedish and international scholars
Mid-Infrared Soliton and Raman Frequency Comb Generation in Silicon Microrings
We numerically study the mechanisms of frequency comb generation in the
mid-infrared spectral region from cw pumped silicon microring resonators.
Coherent soliton comb generation may be obtained even for a pump with zero
linear cavity detuning, through suitable control of the effective lifetime of
free-carriers from multiphoton absorption, which introduces a nonlinear cavity
detuning via free-carrier dispersion. Conditions for optimal octave spanning
Raman comb generation are also described
Causal Powers and Social Ontology
Over the last few decades, philosophers and social scientists have applied the so-called powers ontology to the social domain. I argue that this application is highly problematic: many of the alleged powers in the social realm violate the intrinsicality condition, and those that can be coherently taken to be intrinsic to their bearers are arguably causally redundant. I end the paper by offering a diagnosis of why philosophers and social scientists have been tempted to think that there are powers in social realm
Elder-Vass on the Causal Power of Social Structures
In this review essay I examine the central tenets of sociologist Dave Elder-Vass’s recent contribution to social ontology, as put forth in his book The Causal Power of Social Structures: Emergence, Structure and Agency (2010). Elder-Vass takes issue with ontological individualists and maintains that social structures exist and have causal powers in their own right. I argue that he fails to establish his main theses: he shows neither that social structures have causal powers “in their own right” (in any sense of this expression) nor that they exist
Endurance Per Se in B-time
Three arguments for the conclusion that objects cannot endure in B-time even if they remain intrinsically unchanged are examined: Carter and Hestevold’s enduring-objects-as-universals argument (American Philosophical Quarterly 31(4):269–283, 1994) and Barker and Dowe’s paradox 1 and paradox 2 (Analysis 63(2):106–114, 2003, Analysis 65(1):69–74, 2005). All three are shown to fail

Can Persistence be a Matter of Convention?
This paper asks whether persistence can be a matter of convention. It argues that in a rather unexciting de dicto sense persistence is indeed a matter of convention, but it rejects the notion that persistence can be a matter of convention in a more substantial de re sense. However, scenarios can be imagined that appear to involve conventional persistence of the latter kind. Since there are strong reasons for thinking that such conventionality is impossible, it is desirable that our metaphysical-cum-semantic theories of persistence be able to account for such scenarios in terms of conventions of the first kind. Later parts of the article therefore investigate whether three of the currently most influential metaphysical-cum-semantic theories of persistence—the endurance theory, the stage theory, and the perdurance theory—can do this. Fortunately, for them, it turns out that all can, though some philosophers have disputed this. However, when we ask how they account for a typical case of “conventional persistence” some problematic features of the theories—having to do with reference, persistence conditions, how they relate, and the epistemology of persistence—are revealed
Too Many Dispositional Properties
This paper identifies an overdetermination problem faced by the non-reductive dispositional property account of disposition ascriptions. Two possible responses to the problem are evaluated and both are shown to have serious drawbacks. Finally it is noted that the traditional conditional analysis of disposition ascriptions escapes the original difficulty
The Tenseless Copula in Temporal Predication
In this paper I explore how the tenseless copula is to be interpreted in sentences of the form “a is F at t”, where “a” denotes a persisting, changeable object, “F” stands for a prima facie intrinsic property and “t” for a B-time. I argue that the interpretation of the copula depends on the logical role assigned to the time clause. Having rejected the idea that the time clause is to be treated as a sentence operator, I argue: (1) that if “at t” is thought of as being associated with “a” or “F”, then the tenseless copula is most plausibly read as an “is” simpliciter; and (2) that if “at t” is treated as being associated with the copula, then the tenseless copula is most plausibly understood as expressing a disjunction of tensed copulas. I end the paper by explaining the importance of the issue. I indicate the ramifications interpretation of the tenseless copula has for the so-called problem of temporary intrinsics
