Bribery or Just Desserts? Evidence on the Influence of Congressional Voting Patterns on PAC Contributions from Exogenous Variation in the Sex Mix of Legislator Offspring [PDF]

open access: yes
Evidence on the relationship between political contributions and legislators' voting behavior is marred by concerns about endogeneity in the estimation process.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Shipping the good apples out: a note on contributions of time and money [PDF]

open access: yes
This note applies insights from a famous problem in price theory, "Shipping the Good Apples Out," to expand the comparative static predictions of the model of monetary donations and volunteering developed by Andreoni, Gale and Scotz (1996).

Prohibited Contributions to Sin and Prohibited Contributions to Oppressor in Mass Media in the Eyes of Islamic Jurisprudence and with an Emphasis on Jurisprudent Speculation of Imam Khomeini (ra) [PDF]

open access: yesسپهر سیاست, 2015
Studying rulings of news broadcast and press is particularly important with a consideration given to age of communications and the need of jurisprudence to respond to matters concerned with the community. In school of Islam, jurisprudence is in charge of

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

On the Desirability of Taxing Charitable Contributions [PDF]

open access: yes
We develop a model that allows for public goods and status signaling through charitable contributions. This model provides a unified framework in which contributions are driven both by altruism and status signaling.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

On Modeling Voluntary Contributions to Public Goods

open access: yes, 2006
This paper addresses four ìstylized factsî that summarize data from experimental studies of voluntary contributions to provision of public goods. Theoretical propositions and testable hypotheses for voluntary contributions are derived from two models of ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Minimizing inbreeding by managing genetic contributions across generations

open access: yes, 2003
Here we present the strategy that achieves the lowest possible rate of inbreeding (DeltaF) for a population with unequal members of sires and dams with random mating. This new strategy results in a DeltaF as much as 10% lower than previously achieved.
