Hasty generalizations and generics in medical research: A systematic review.

PLoS ONE
It is unknown to what extent medical researchers generalize study findings beyond their samples when their sample size, sample diversity, or knowledge of conditions that support external validity do not warrant it.

Determinantal Generalizations of Instrumental Variables

Journal of Causal Inference, 2018
Linear structural equation models relate the components of a random vector using linear interdependencies and Gaussian noise. Each such model can be naturally associated with a mixed graph whose vertices correspond to the components of the random vector.

Musical generalizations [PDF]

, 2009
The term “Musical generalizations” refers to generalizations of artefacts – signs and tools – in a music context. Issues about these generalizations are defined by means of cultural historical activity theory.

Layers of Generality and Types of Generalization in Pattern Activities (Niveles de Generalidad y Tipos de Generalizaciones en Actividades de Patrones) [PDF]

PNA: Revista de Investigación en Didáctica de la Matemática, 2010
Pattern generalization is considered one of the prominent routes for introducing students to algebra. However, not all generalizations are algebraic. In the use of pattern generalization as a route to algebra, we —teachers and educators— thus have to ...

On Distance (r,k)-Fibonacci Numbers and Their Combinatorial and Graph Interpretations

Journal of Applied Mathematics, 2015
We introduce three new two-parameter generalizations of Fibonacci numbers. These generalizations are closely related to k-distance Fibonacci numbers introduced recently. We give combinatorial and graph interpretations of distance (r,k)-Fibonacci numbers.

New Conformally Invariant Born–Infeld Models and Geometrical Currents

Physics
A new conformally invariant gravitational generalization of the Born–Infeld (BI) model is proposed and analyzed from the point of view of symmetries. Taking a geometric identity involving the determinant functions detfBμν, Fμν with the Bach Bμν and the ...

The Generalizations of Hilbert's Inequality

International Journal of Mathematics and Mathematical Sciences, 2008
By introducing some parameters and estimating the weight functions, we establish a new Hilbert-type inequalities with best constant factors. The equivalent inequalities are also considered.

Completions of Kleene's second model [PDF]

Logical Methods in Computer Science
We investigate completions of partial combinatory algebras (pcas), in particular of Kleene's second model $\mathcal{K}_2$ and generalizations thereof. We consider weak and strong notions of embeddability and completion that have been studied before in ...
