The Inverse Lewbel Demand System

open access: yesJournal of Agricultural and Resource Economics, 1994
A new model of consumer preferences is introduced. It is appropriate for modeling perishable commodities which are produced with a lag, where it is reasonable to assume the market-level quantities are fixed by previously made production decisions.

Form over Function? [PDF]

open access: yesJournal of Biological Rhythms, 2002
In this issue of the Journal of Biological Rhythms, Zhou et al. (2002) present data from several experiments aimed at identifying effects of photoperiod on the immune systems of two well-established photoperiodic model species: Siberian hamsters (Phodopus sungorus) and Syrian hamsters (Mesocricetus auratus).

Forms and Functions [PDF]

open access: yesThe Mathematical Gazette, 1957
The two essentially different concepts of “form” and “function” are sometimes confused in elementary text-books, and in this note I set out to stress one or two important formal results, in particular the formal interpretation of the binomial theorem for a negative integral exponent.

Functional Form and U.S. Agricultural Production Elasticities

open access: yesJournal of Agricultural and Resource Economics, 1993
Because so much agricultural policy analysis utilizes estimates of supply and demand elasticities, it is crucial to obtain the most reliable estimates possible.

Human intellectual disability genes form conserved functional modules in Drosophila. [PDF]

open access: yesPLoS Genetics, 2013
Intellectual Disability (ID) disorders, defined by an IQ below 70, are genetically and phenotypically highly heterogeneous. Identification of common molecular pathways underlying these disorders is crucial for understanding the molecular basis of ...

Truth-Functional Logic and the Form of a Tractarian Proposition [PDF]

open access: yesPublic Reason, 2022
In this paper I argue against Michael Morris’ claim, that the Tractatus view involves holding that the possibility of truth-functional combination is prior to the possibility for sentential constituents to combine with one another.

Multiple-Output Production Modeled with Three Functional Forms

open access: yesJournal of Agricultural and Resource Economics, 1992
Aggregate dual models are specified to examine multiple-output production relationships in each of four major, geographically dispersed, agricultural states (California, Iowa, Texas, and Florida).

Privileged (Default) Causal Cognition: A Mathematical Analysis

open access: yesFrontiers in Psychology, 2018
Causal cognition is a key part of human learning, reasoning, and decision-making. In particular, people are capable of learning causal relations from data, and then reasoning and planning using those cognitive representations.

Transporter oligomerization: form and function [PDF]

open access: yesBiochemical Society Transactions, 2016
Transporters are integral membrane proteins with central roles in the efficient movement of molecules across biological membranes. Many transporters exist as oligomers in the membrane. Depending on the individual transport protein, oligomerization can have roles in membrane trafficking, function, regulation and turnover. For example, our recent studies

Changes in Competitors, Stress Tolerators, and Ruderals (CSR) Ecological Strategies after the Introduction of Shrubs and Trees in Disturbed Semiarid Steppe Grasslands in Hulunbuir, Inner Mongolia

open access: yesBiology, 2023
To reveal the changes in the life history characteristics of grassland plants due to vegetation restoration, plant species and communities were analyzed for their competitor, stress tolerator, and ruderal (CSR) ecological strategies after the ...
