Harmful Algal Blooms (HABs) pose unique risks to the citizens, stakeholders, visitors, environment and economy of state Florida. Florida has been historically subjected reoccurring blooms toxic marine dinoflagellate Karenia brevis (C. C. Davis) G. Hansen & Moestrup since at least first contact with explorers in 1500’s. However, ongoing immigration more than 100,000 people year –1 into s...
In this paper we study the influence of economic stability on the level of corruption in a country, where high stability is defined as a low level of variance in economic output growth. We present a political competition model with exogenous shocks to economic output where politicians can decide about the level of corruption and an election is held within the framework of a Bayesian game. Corru...
R ecent years have seen an unprecedented number of official efforts to improve, develop, and implement new measures of the quality of life and economic performance. Much of the groundwork for these efforts was laid in two important National Research Council reports. Nature's Numbers, published in 1999, considered how to expand the national income accounts that track the country's economic activ...
BACKGROUND From 2008 on, a severe economic crisis (EC) has characterized the European Union (E.U.). However, changes in substance use behavioral patterns as a result of the economic crisis in Europe, have been poorly reflected upon, and underlying mechanisms remain to be identified; METHODS In this review we explore and systematize the available data on the effect of the 2008 economic crisis ...
Economic sociologists and white-collar criminologists offer competing predictions about the outcomes of socially embedded transactions. Economic sociologists stress the protective and beneficial role of social networks. Their evidence shows that social ties improve transaction outcomes. White-collar criminologists focus on the harmful and exploitative role of social networks. Their evidence sho...
Background : One of the harmful and distressful events which may happen throughout everybody's life is burn. Most often the problems and complication of burn has ever- lasting effects. Burn deformities can lead to progressive isolation of victim and psychosocial problems. Objective : To determine psychosocial problems of client suffering from burn's defect and it's relation to demographic d...
Harmful benthic microalgae blooms represent an emergent phenomenon in temperate zones, causing health, ecological and economic concern. The main goal of this work was to compile records of Ostreopsis at large temporal and spatial scales, in order to study the relationship between cell abundances, the periodicity and intensity of the blooms and the role of sea water temperature in 14 Spanish, Fr...
harmful economic, environmental and financial impacts of fertilizer distribution through subsidies as well as its contradiction with regulations of wto, it makes necessary to adopt a new policy. in this study, by combining positive mathematical programming and maximum entropy technique, the impacts of cancellation of fertilizer subsidies and applying proposed direct payment policies on gross ma...
Evidence indicates that the incidence of cyanobacterial harmful algal blooms (CHABs) is increasing in spatial extent and temporal frequency worldwide. Cyanobacterial blooms produce highly potent toxins and huge, noxious biomasses in surface waters used for recreation, commerce, and as drinking water sources. The Interagency, International Symposium on Cyanobacterial Harmful Algal Blooms (ISOC-H...
In this paper, we investigate the dynamic behaviors of a Holling II two-prey one-predator system with impulsive effect concerning biological control and chemical control strategy-periodic releasing natural enemies and spraying pesticide at different fixed moment. By using the Floquet theory of linear periodic impulsive equation and small-amplitude perturbation method, we show that there exists ...
