What’s positive and negative about generics: a constrained indexical approach

Type - constrained Generics for ZSamuel

We propose an extension to Z whereby generic parameters may have their types partially constrained. Using this mechanism it becomes possible to deene in Z much of its own schema calculus and re-nement rules.

Content Internalism about Indexical Thought

Properly understood, content internalism is the thesis that any difference between the representational contents of two individuals’ mental states reduces to a difference in those individuals’ intrinsic properties. Some of the strongest arguments against internalism turn on the possibility for two “doppelgangers” – perfect physical and phenomenal duplicates – to differ with respect to the conte...

A Cross-Cultural Study about Positive and Negative Emotions and Its Relation to Health and Well-being

Parental Reminiscing About Positive and Negative Events

We examined how 67 parent–child dyads talked about 2 emotionally laden events: an injury resulting in emergency room treatment and an individually nominated, positively valenced experience. Group differences were found in parental reminiscing between positive and negative events such that parents asked a higher proportion of open-ended memory questions in conversations about negative experience...

Essentially Negative News About Positive Systems

In this paper the discretisation of switched and non-switched linear positive systems using Padé approximations is considered. Padé approximations to the matrix exponential are sometimes used by control engineers for discretising continuous time systems and for control system design. We observe that this method of approximation is not suited for the discretisation of positive dynamic systems, f...
