A nonverbal false belief task was administered to children (mean age 5 years) and two great ape species: chimpanzees (Pan troglodytes) and bonobos (Pan paniscus). Because apes typically perform poorly in cooperative contexts, our task was competitive. Two versions were run: in both, a human competitor witnessed an experimenter hide a reward in one of two containers. When the competitor then lef...

In this paper we consider the problem of regulating an open access essential facility. A vertically integrated firm owns an essential input and operates on the downstream market under the roof of a regulatory mechanism. There is a potential entrant in the downstream market. Both competitors use the same essential input to provide the final services to the consumers. The regulator designs a mech...

In species with alternative reproductive tactics, males that sneak copulations often have larger, higher quality ejaculates relative to males that defend females or nest sites. Ejaculate traits can, however, exhibit substantial phenotypic plasticity depending on a male's mating role in sperm competition, which may depend on the tactic of his competitor. We tested whether exposure to males of di...

The nuclear protein regulator of chromosome condensation 1 (RCC1) stimulates guanine nucleotide exchange on a protein, Ran, that is required for nuclear protein import. In the present report, we confirm that RCC1 is also required for nuclear protein import in tsBN2 hamster cells in vivo. The thermolability of nuclear protein import in tsBN2 cells was suppressed by microinjection of purified Ran...

Mitochondrial protein import is thought to involve the sequential interaction of preproteins with binding sites on cis and trans sides of the membranes. For translocation across the outer membrane, preproteins first interact with the cytosolic domains of import receptors (cis) and then are translocated through a general import pore, in a process proposed to involve binding to a trans site on th...

The NH2 terminus of the yeast F1-ATPase beta subunit precursor directs the import of this protein into mitochondria. To define the functionally important components of this import signal, oligonucleotide-directed mutagenesis was used to introduce a series of deletion and missense mutations into the gene encoding the F1-beta subunit precursor. Among these mutations were three nonoverlapping dele...

Using streptolysin-O (SLO) we have developed a permeabilized cell system retaining the competence to import proteins into peroxisomes. We used luciferase and albumin conjugated with a peptide ending in the peroxisomal targeting sequence, SKL, to monitor the import of proteins into peroxisomes. After incubation with SLO-permeabilized cells, these exogenous proteins accumulated within catalase-co...

Fructose-1,6-bisphosphatase (FBPase) is targeted to the vacuole for degradation when Saccharomyces cerevisiae are shifted from low to high glucose. Before vacuolar import, however, FBPase is sequestered inside a novel type of vesicle, the vacuole import and degradation (Vid) vesicles. Here, we reconstitute import of FBPase into isolated Vid vesicles. FBPase sequestration into Vid vesicles requi...

In recent decades, theorists proposed the role of domestic components such as interior active groups, policies and macroeconomic indicators on determination of protection policies. In the context of recent studies, this study has investigated the effect of business cycle fluctuations on import protection for selected developing countries in 1995-2011 by using dynamic panel data method. Furtherm...
