Identifying bottom-up (e.g., physical and biogeochemical) drivers for fish catch is essential sustainable fishing successful adaptation to climate change through reliable prediction of future fisheries. Previous studies have suggested the potential linkage such as ocean temperature or satellite-retrieved chlorophyll concentration across different global ecosystems. Robust estimation effects on ...

This paper examines how equity analysts affect corporate liquidity policy and the value of cash. Greater analyst coverage reduces information asymmetry between a firm and outside shareholders and enhances the monitoring process, in turn increasing the value of cash and allowing firms to hold more cash. The cash-to-assets ratio increases by 5.2 percentage points when moving from the bottom analy...

Entities define their own set of rules under which they are willing to collaborate, e.g., interact, share and exchange resources or information with others. Typically, these individual policies differ for different parties. Thus, collaboration requires the resolving of differences and reaching a consensus. This process is generally referred to as policy reconciliation. Current solutions for pol...

The pharmaceutical supply chain is composed of multiple firms interacting to produce and distribute drugs in an uncertain environment. In this work, we develop and validate a multi-agent simulation of the supply chains associated with the pharmaceutical industry. We demonstrate that the operating norms of a particular industry can be accurately represented to create an industry-specific model c...

Baltic seals are recovering after a population decline. The increasing seal stocks cause notable damage to fisheries in the Baltic Sea, with an unknown number of seals drowning in fishing gear every year. Thus, sustainable seal management requires updated knowledge of the by-catch of seals--the number of specimens that die in fishing gear. We analyse the by-catch of grey seals (Halichoerus gryp...

The shrimp fishery is the most economically important fishery in Mexico. The trawler-based portion of this fishery results in high rates of by-catch. This study quantifies and describes the biodiversity of by-catch associated with trawling in the Bahía de Kino region of Sonora, Mexico. Data were collected from 55 trawls, on six boats, over 14 nights, during November of 2003, 2004, 2006-2009. By...

Portfolios are selected in non-Gaussian contexts to maximize a Cherny and Madan index of acceptability. Analytical gradients are developed for the purpose of optimizing portfolio searches on the unit sphere. It is shown that though an acceptability index is not a preference ordering, many utilities will concur with acceptability maximization. A stylized economy illustrates the advantages from t...

The relationship between annual water level of Danube and annual catches of Pontic shad (Alosa immaculata, Bennett 1835) in Romania were analyzed. For analysis of long term data on the Danube water level and Pontic shad catch (1920-2013), combinations of different methods were applied using programs Statistica, SPSS 13.0 and MATLAB 6. Periodograms, containing cyclic patterns, were obtained usin...

A persistent infection with human papillomavirus (HPV) is a prerequisite for the development of cervical cancer. Clinical trials with HPV-vaccines have been very successful in preventing persistent HPV16/18 infections, the two most oncogenic HPV-genotypes. We assessed the introduction of universal HPV-vaccination for preadolescent girls in the Dutch National Immunization Programme. Long-term va...
