Does gene dosage really matter?

Mechanisms to compensate for dosage differences of genes on sex chromosomes are widespread in animals and have been thought to be critical for viability. However, in birds, compensation is inefficient, implying that for many genes dosage compensation is not critical, and for some genes, dosage differences have even been selected for

Are homologies in vertebrate sex determination due to shared ancestry or to limited options?

The bewildering array of different sex-determination systems in vertebrates is built on a common set of genes and chromosomes

Toward Common Content: An Analysis of Online College and University Collecting Policies

Collecting policies have been advocated as tools to help archivists build stronger collections. The model proposed by Faye Phillips in 1984 is the most detailed framework for collecting policies in the archival literature. This paper presents the results of a pilot study of the collecting policies of college and university archives available online to investigate whether a consensus has been reached about the content of these documents. Future studies of this kind for other types of archives could facilitate the identification, refinement, and dissemination of professional best practice and standards for collecting policies

Police surveillance of cell phone location data: Supreme Court versus public opinion

The Fourth Amendment to the US Constitution protects individuals from unreasonable searches and seizures. As technology evolves, courts must examine Fourth Amendment concerns implicated by the introduction of new and enhanced police surveillance techniques. Recent Supreme Court cases have demonstrated a trend towards reconsidering the mechanical application of traditional Fourth Amendment doctrine to define the scope of constitutional protections for modern technological devices and personal data. The current research examined whether public opinion regarding privacy rights in electronic communications is in accordance with these Supreme Court rulings. Results suggest that cell phone location data is perceived as more private and deserving of protections than other types of location data, but the privacy of other types of information recorded on cell phones is valued even more than location data. These results have implications for the police and courts considering how the Fourth Amendment will apply to smart phone technologies
