A systems analysis perspective is adopted to examine the critical properties of the Free/Libre/Open Source Software (FLOSS) mode of innovation, as reflected on the SourceForge platform (SF.net). This approach re-scales March’s (1991) framework and applies it to characterize the “innovation system” of a “distributed organization” of interacting agents in a virtual collaboration environment, rath...

Multinational firms expanding into emerging markets can choose between entry through a greenfield project and via an acquisition. This paper analyzes this strategic decision. Among the options for entry mode, brownfield is delineated as a special case of acquisition, in which the resources transferred by the investor dominate over those provided by the acquired firm. Our analytical framework dr...

In all vertebrate embryos, segmental streams of cranial neural crest cells migrate to form the pharyngeal arches and differentiate into cartilages and bones of the head skeleton. In gnathostomes, the head skeleton has a dorsoventral (DV) polarity from its first appearance: dorsal and ventral cartilages of different shapes (such as the upper jaw and lower jaw in the first arch) are separated by ...

This paper applies six recently developed nonparametric tests of serial independence to monthly US stock returns. Findings of previous studies based on the BDS test are supported since most of the new tests also reject the random walk hypothesis. Furthermore, power properties of the new tests are compared with those of the BDS test. The latter has much power against ARCH and GARCH alternatives ...

We curated a dataset containing 5999 records of 361 freshwater fish species (~70% known in the country) and 483 endo- ectoparasitic helminths registered throughout Mexico over an 85-year period (from 1936 to 2021). Taxonomically, highest numbers host corresponded family Cichlidae, parasites trematode Diplostomidae. hope this will encourage researchers worldwide explore different ecological coev...

Lawns require a steady supply of nitrogen (N) to maintain green color and seasonal shoot density. Excess N fertilization can lead surface groundwater contamination, suggesting need for alternative turf strategies that reduce the reliance on frequent applications. Grass-legume mixtures may be one solution since legumes, like white clover (Trifolium repens L.), biologically fix atmospheric add it...

INTRODUCTION Symptoms of dyspepsia are common but most patients do not have major upper gastrointestinal pathology. Endoscopy is recommended for dyspeptic patients over the age of 45, or those with certain "alarm" symptoms. We have evaluated the effectiveness of age and "alarm" symptoms for predicting major endoscopic findings in six practising endoscopy centres. METHODS Clinical variables of...
