| ABSTRACT The objective of this study was to identify and quantify, through mathematical models, the main factors of production in growing and finishing pig units linked to three Brazilian cooperatives located in Western Region of Paraná State that influence the parameters of daily feed intake and feed conversion ratio. The records of 216 growing and finishing farms from 2010 to 2013, representing 1,533 batches, and totaling approximately 1,025,000 pigs, were evaluated. Thirty production factors related to the management, health, installations and equipment, nutrition, genetics, and environment were considered. The number of pigs per pen, the feeder model, the origin and sex of the animals, and the initial and final body weights were the factors included in... |

| We conducted a study of the processes associated to NH3 emission in naturally ventilated dairy cattle facilities, having described factors that regulate NH3 emission, as well as methodologies for measuring these emissions at these facilities. Appropriate techniques to mitigate NH3 emission in facilities located in regions with warm climates were also identified. The most effective mitigation techniques with simple implementation include strategies associated to: (i) installation design and flooring, which lead to reduced emissions, (ii) excreta pre-excretion, namely the use of diets with optimized crude protein content and increased milk production at farm level; and (iii) excreta post-excretion, particularly by changing the conditions of environmental... |

| Random Utility Models of recreation demand are widely used to relate demand and value to the characteristics of recreation sites. Although some kinds of endogeneity problems have been studied in previous literature, no study has addressed the potential problem with site characteristics that are endogenously supplied. Some site characteristics, like facilities, could be endogenous in an economic sense due to the interplay of supply and demand. That is, more popular recreation sites tend to have better site characteristics since managers with limited budgets would be more willing to invest in them. If recreation site improvements are more likely to occur at the more popular sites, then this economic endogeneity might cause problems for econometric models... |

| Different kinds of endogeneity problems in Random Utility Models of recreation demand have been studied in previous literature. Some site characteristics, like facilities, could be endogenous in an economic sense due to the interplay of supply and demand. That is, it may be that more popular recreation sites tend to have better site characteristics since managers with limited budgets would be more willing to invest in them. If recreation site improvements are more likely to occur at the more popular sites, then might this economic endogeneity cause problems for econometric models linking site demand to facilities. In this paper, we use Monte Carlo simulations to test whether this economic endogeneity will lead to statistical endogeneity. |

| Megállapítható, hogy a Balatonnál a kis- és közepes vállalkozások csak úgy képesek felvenni a versenyt a globalizáció következtében piacot hódító multina-cionális vállalatokkal, hogy üzlethálózatokba tömörülnek. A kis- és középvállal-kozásoknak kínálnak megoldást a szövetkezetek, amelyek üzletláncok kiépítésé-vel, az ország egészére kiterjedő élelmiszer-kiskereskedelmi hálózattal rendel-keznek. Az azonos logo már maga is forgalomstabilizáló tényező, az egységes ár-politika, az országosan és regionálisan összehangolt árengedményes akciók hoz-zájárulnak a forgalom növekedéséhez, igazodva a magyarországi fogyasztói pi-achoz és vásárlási szokásokhoz. Tulajdonosi és szerkezeti viszonyait illetően sajá-tos kettősség jellemzi a kereskedelmet. Az egyik oldalon a... |
