Cost efficiency and UK building societies. An econometric panel-data study employing a flexible fourier functional form [PDF]

open access: yes, 1998
The paper empirically quantifies firm specific 'distribution free' cost efficiency, economies of scale and economies of scope in the UK building society sector between 1990-1995. Both a flexible Fourier and a translog functional form are employed with

Justification for inclusion dependency normal form [PDF]

open access: yes, 2000
Functional dependencies (FDs) and inclusion dependencies (INDs) are the most fundamental integrity constraints that arise in practice in relational databases.

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.

A Functional Form for Fine Sediment Interception in Vegetated Environments

open access: yesGeosciences, 2021
The body of literature seeking to evaluate particle interception in vegetated, aquatic environments is growing; however, comparing the results of these studies is difficult due to large variation in flow regime, particle size, vegetation canopy density ...

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.

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.

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.

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 ...

Reducing Approximation Error in the Fourier Flexible Functional Form

open access: yesEconometrics, 2017
The Fourier Flexible form provides a global approximation to an unknown data generating process. In terms of limiting function specification error, this form is preferable to functional forms based on second-order Taylor series expansions.
