Mast years increase wind pollination and reduce seed predation in sugar maple (Acer saccharum)

American Journal of Botany, EarlyView.
Abstract Premise In general, mast seeding (intermittent and synchronous seed production) increases plant fitness through economies of scale in which reproduction is more successful in high‐seed years. These benefits have been most studied in wind‐pollinated trees.

Land re-use, complexity and actor-networks: a framework for research [PDF]

, 2004
This paper will present a conceptual framework for the examination of land redevelopment based on a complex systems/networks approach. As Alvin Toffler insightfully noted, modern scientific enquiry has become exceptionally good at splitting problems into

Educating teachers toward immigrant empowerment and liberation in the United States and Chile: A funds of knowledge perspective

American Journal of Community Psychology, EarlyView.
Abstract This article examines how university‐based teacher education programs in diverse historical, sociocultural, and political settings in the U.S. and in Chile, served to foster immigrant empowerment and liberation. Using a Funds of Knowledge approach, the study analyzed the educational practices of migrant families and their integration into ...

Some dynamical properties for linear operators [PDF]

arXiv, 2009
In our another recent article, we introduce a new dynamical property for linear operators called norm-unimodality which implies distributional chaos. In the present paper, we'll give a further discussion of norm-unimodality. It is showed that norm-unimodality is similar invariant and the spectra of norm-unimodal operator is referred to.

A study of chaos and randomness in quantum systems [PDF]

arXiv
How classical chaos emerges from the underlying quantum world is a fundamental problem in physics. The origin of this question is in the correspondence principle. Classical chaos arises due to non-linear dynamics, whereas quantum mechanics, driven by unitary evolution, is linear. The question that still remains is - what are the footprints of classical

Survey sabotage: Insights into reducing the risk of fraudulent responses in online surveys

Anatomical Sciences Education, EarlyView.
Abstract Validity is a key element of many forms of research—particularly surveys, which are often used in health professions education research. A survey must accurately measure what it is intended to measure to be considered valid. This is becoming increasingly difficult in the age of artificial intelligence (AI), where “bots” (short for robots) are ...
