| ABSTRACT The aim of this study was to evaluate the frequency of isolation of agents causing subclinical mastitis in a herd and to estimate production losses associated with SCC> 200,000cells/mL. Three 7-day interval microbiological cultures were performed in all lactating animals from the same farm that was evaluated from June to July. To evaluate the negative and positive isolation frequencies between the lactation phases, a Chi-square test was performed. Simple linear regressions were performed to evaluate the lactation curve of animals grouped by pathogens isolated from negative cows in the microbiological culture and with SCC <200,000cells/mL. To estimate the production losses between the groups, regression coefficients were used. Results found... |

| Correlations of measures of percentages of white coat color, five measures of production and two measures of reproduction were obtained from 4293 first lactation Holsteins from eight Florida dairy farms. Percentages of white coat color were analyzed as recorded and transformed by an extension of Box-Cox procedures. Statistical analyses were by derivative-free restricted maximum likelihood (DFREML) with an animal model. Phenotypic and genetic correlations of white percentage (not transformed) were with milk yield, 0.047 and 0.097; fat yield, 0.002 and 0.004; fat percentage, -0.047 and -0.090; protein yield, 0.024 and 0.048; protein percentage, -0.070 and -0.116; days open, -0.012 and -0.065; and calving interval, -0.007 and -0.029. Changes in magnitude of... |

| ABSTRACT The in vitro susceptibility of 105 clinical and environmental strains of Aspergillus fumigatus and Aspergillus flavus to antifungal drugs, such as amphotericin B, azoles, and echinocandins was evaluated by the broth microdilution method proposed by the European Committee on Antimicrobial Susceptibility Testing (EUCAST). Following the EUCAST-proposed breakpoints, 20% and 25% of the clinical and environmental isolates of A. fumigatus, respectively, were found to be resistant to itraconazole (Minimal Inhibitory Concentration, MIC > 2.0 mg/L). Voriconazole showed good activity against A. fumigatus and A. flavus strains, except for one clinical strain of A. fumigatus whose MIC was 4.0 mg/L. Posaconazole (≤0.25 mg/L) also showed appreciable activity... |

| Many maritime countries in Europe have implemented marine environmental monitoring programmes which include the measurement of chemical contaminants and related biological effects. How best to integrate data obtained in these two types of monitoring into meaningful assessments has been the subject of recent efforts by the International Council for Exploration of the Sea (ICES) Expert Groups. Work within these groups has concentrated on defining a core set of chemical and biological endpoints that can be used across maritime areas, defining confounding factors, supporting parameters and protocols for measurement. The framework comprised markers for concentrations of, exposure to and effects from, contaminants. Most importantly, assessment criteria for... |

| Major changes affecting Agricultural Economics include: level and sources of funding, increased accountability, a renewed emphasis on teaching, increasing university and college linkages, an evolving student base, and the continuing adoption of educational technology. Major implications include: broader faculty teaching involvement, agribusiness program development, expanding multidisciplinary majors, Ph.D program modifications for teacher preparation, expanding professional M.S. degrees, graduate program size and specialization reductions, alternative financing of graduate education, and faculty training in teaching methods. Teaching represents a major growth opportunity for Agricultural Economics, but it remains to be seen whether the discipline takes... |

| Kutatásunk célja fényt deríteni arra, hogy a vállalkozások környezeti teljesítménye befolyásolja-e pénzügyi teljesítményüket, továbbá az, hogy milyen szerepet játszik ebben a média, hogyan változott az elmúlt időszakban a vállalkozások zöld erőfeszítéseinek megítélése? Megállapítható, hogy azokban a vállalkozásokban, amelyekben a média és a befektetők környezeti teljesítményüket kedvezően ítélik meg, magasabbak a megtérülési (ROE) mutatók, mint azokban, amelyeknek környezeti teljesítményét nem ítélik meg pozitívan. A magyarországi társadalomban a nem anyagi értékek iránti érzékenység és a környezettudatosság alacsony szintű. A társadalmi értékrendben alárendelt szerepet játszó környezetvédelmi gondolkozásra – reklámérték híján – a média mérsékelten hat. Ez... |

| I analyze the problem faced by an asymmetrically informed supranational governmental authority (SNGA) with limited financial resources who wishes to design an International Environmental Agreement (IEA). The SNGA cannot contract directly with polluting firms in the various LDCs, but he must deal with such firms through their governments. I study this tripartite hierarchical interaction and focus on the properties of the optimal ex post contracts (IEAs), which can be implemented by the SNGA, in turn, in the case where governments and firms in each nation do not collude and then in the case where governments and firms do collude. I find that the monetary transfers necessary to induce optimal behavior by governments and firms are not very sensitive to the... |

| In this paper we study some aspects of the question of international environmental regulation from a game theoretic perspective. We address two broad questions. First, we examine the circumstances under which the pursuit of unilateral environmental policy by a country in a Stackelberg game will make that country worse off. Second, we study the effects of environmental regulation by means of alternate price control instruments in a Stackelberg game where there is transboundary pollution. We find that there are plausible theoretical circumstances in which the pursuit of unilateral environmental policy is not a good idea. Further, we show that in choosing between alternate pollution control instruments, national governments typically face a tradeoff between... |

| The combination of a general greening of international political debate, and the events of 1992 at the Rio Earth summit have led to great interest in the question of global environmental protection. While it is recognized that international environmental agreements (IEAs) are the means by which the earths fragile environment is most likely to be protected, this recognition has been recent. Hence, there is very little formal research on the design and study of IEAs. As such, in this paper, I propose and describe a research agenda for the design and study of IEAs. Very generally, I propose that we frame the IEA design question as a problem in mechanism design. We will then be able to use, inter alia, the theory of common agency and the theory of hierarchies... |
