Amazon.com’s Elastic Compute Cloud (EC2), Simple Storage Service (S3) and Simple Queue Service (SQS) offer enterprise-class computing, storage and coordination facilities to any organization or individual in the world with a valid credit card. This paper details our experience working with these commodity grid computing services between November 2006 and May 2007, including an analysis of the o...

Hindi-Urdu displays an asymmetry with respect to the availability of Closest Conjunct Agreement. It is available only to objects and not to subjects. Agreement with subjects is always agreement with the full conjunct. We argue that this asymmetry in Conjunct Agreement is related to another asymmetry between subject and object agreement in Indo-Aryan languages: object agreement never involves pe...

The concurrent circumstances of an increasingly mobile workforce, disparities in access to healthcare, and the ability to deliver care through technology (e.g., telehealth) present the need and the opportunity for practice across state borders. Over the past four years, the Federation of State Boards of Physical Therapy (FSBPT) has explored professional licensure models that will allow cross bo...

Object drop constructions are attested in several languages despite the absence of overt verb-object agreement (Cole 1987; Huang 1995). It has been claimed that languages vary crosslinguistically in the conditions licensing object drop: European and Brazilian Portuguese (Farrell 1990; Raposo 1986) and Quiteño Spanish (Suñer and Yépez 1988) license null objects only for definite NPs (cf. (1), (2...

that restrict trade between countries in agricultural commodities. Many of these policies are now subject to important disciplines under the 1994 GATT agreement that is administered by the World Trade Organization (WTO). The paper is organized as follows. First, tariffs, import quotas, and tariff rate quotas are discussed. Then, a series of non-tariff barriers to trade are examined, including v...

Because of a deterioration in the quality of the environment, this paper studies the effects of the environment and the economy on environmental technology licensing in a homogeneous Cournot duopoly model in order to reduce environmental pollution and hence improve social welfare. To this end, two licensing methods — namely, a fixed-fee licensing method and a royalty licensing method — are comp...

When we look at the rapid growth of scientific databases on the Internet in the past decade, we tend to take the accessibility and provenance of the data for granted. As we see a future of increased database integration, the licensing of the data may be a hurdle that hampers progress and usability. We have formulated four rules for licensing data for open drug discovery, which we propose as a s...

To maintain genome stability, the thousands of replication origins of mammalian genomes must only initiate replication once per cell cycle. This is achieved by a strict temporal separation of ongoing replication in S phase, and the formation of pre-replicative complexes in the preceding G1 phase, which "licenses" each origin competent for replication. The contribution of the loading factor Cdc6...

The replication licensing system ensures the precise duplication of chromosomal DNA in each cell cycle. In metazoans, a small protein called geminin plays a central role in negatively regulating licensing late in the cell cycle. Recent work using Xenopus egg extracts shows how geminin activity is downregulated on exit from metaphase in a process that requires mitotic cyclin-dependent kinases (C...

impact of licensing on hourly wages is much smaller than in the United States. The major empirical findings in Licensing Occupations are summarized in Table 1. Given these results of the labor market impacts of licensing, other forms of regulation, such as certification, are suggested. Alternative forms of occupational regulation may provide consumers with more choice than licensing and reduce ...
