This dissertation studies technological change in the context of energy and environmental economics. Technology plays a key role in reducing greenhouse gas emissions from the transportation sector. Chapter 1 estimates a structural model of the car industry that allows for endogenous product characteristics to investigate how gasoline taxes, R&D subsidies and competition affect fuel efficiency and vehicle prices in the medium-run, both through car-makers' decisions to adopt technologies and through their investments in knowledge capital. I use technology adoption and automotive patents data for 1986-2006 to estimate this model. I show that 92% of fuel efficiency improvements between 1986 and 2006 were driven by technology adoption, while the role of knowledge capital is largely to reduce the marginal production costs of fuel-efficient cars. A counterfactual predicts that an additional $1/gallon gasoline tax in 2006 would have increased the technology adoption rate, and raised average fuel efficiency by 0.47 miles/gallon, twice the annual fuel efficiency improvement in 2003-2006. An R&D subsidy that would reduce the marginal cost of knowledge capital by 25% in 2006 would have raised investment in knowledge capital. This subsidy would have raised fuel efficiency only by 0.06 miles/gallon in 2006, but would have increased variable profits by $2.3 billion over all firms that year. Passenger vehicle fuel economy standards in the United States will require substantial improvements in new vehicle fuel economy over the next decade. Economic theory suggests that vehicle manufacturers adopt greater fuel-saving technologies for vehicles with larger market size. Chapter 2 documents a strong connection between market size, measured by sales, and technology adoption. Using variation consumer demographics and purchasing pattern to account for the endogeneity of market size, we find that a 10 percent increase in market size raises vehicle fuel efficiency by 0.3 percent, as compared to a mean improvement of 1.4 percent per year over 1997-2013. Historically, fuel price and demographic-driven market size changes have had large effects on technology adoption. Furthermore, fuel taxes would induce firms to adopt fuel-saving technologies on their most efficient cars, thereby polarizing the fuel efficiency distribution of the new vehicle fleet.

Antecedentes. Las enfermedades provocadas por parásitos, constituyen problemas serios de salud en la población, presentan una alta incidencia de infección por parásitos intestinales, Objetivo: Determinar la prevalencia de parasitismo en los niños del Centro de Apoyo Nutricional y Pedagógico Santo Hermano Miguel. Cuenca Septiembre 2015 - Enero 2016. Método y materiales: Se realizó un estudio de tipo descriptivo de corte transversal. Se trabajó con una población infantil de 100 niños que va entre 5 a 11 años. Los resultados obtenidos tuvieron un uso confidencial exclusivamente para fines de investigación y fueron analizados mediante software SPSS 15 y Excel. Resultados: El 25% de la población infantil es del género masculino, y el 75 % femenino, de los cuales el 80% presenta parasitismo, el 65% mono parasitismo y el 35% poli parasitismo. Las especies patógenas observadas son: Entamoeba histolytica 85%, Giardia lamblia 3,8%, Trichomona intestinalis 1,3% y Taenia saginata 2,5%.Según las características socioeconómicas, el 100% de la población consume agua potable. El 83% se lavan las manos antes de comer, el 71% lava las frutas antes de consumirlas, el 100% utiliza el servicio sanitario, a su vez el 42% presentan dolor abdominal, el 12% presentan diarrea, el 14% tiene prurito anal y el 46% tiene falta de apetito. Conclusiones: Los hábitos de higiene personal y de alimentación no se están llevando de la forma correcta por ello existe un porcentaje alto de parasitismo, por más que se cuente con los servicios básicos, esto no garantiza un parasitismo negativo

BACKGROUND: Recently, studies have been conducted examining the efficacy of 3% hypertonic saline solution (HS) for the treatment of traumatic brain injury; however, few studies have analyzed the effects of 3% hemorrhagic shock during hemorrhagic shock. The aim of this study was to test the potential immunomodulatory benefits of 3% hemorrhagic shock resuscitation over standard fluid resuscitation. METHODS: Wistar rats were bled to a mean arterial pressure of 35 mm Hg and then randomized into 3 groups: those treated with lactated Ringer`s solution (LR; 33 mL/kg, n = 7), 3% HS (10 mL/kg, n = 7), and 7.5% HS (4 mL/kg, n = 7). Half of the extracted blood was reinfused after fluid resuscitation. Animals that did not undergo shock served as controls (n = 5). Four hours after hemorrhagic shock, blood was collected for the evaluation of tumor necrosis factor-a and interleukin-6 by enzyme immunoassay. Lung and intestinal samples were obtained for histopathologic analysis. RESULTS: Animals in the HS groups had significantly higher mean arterial pressure than those in the LR group 1 hour after treatment. Osmolarity and sodium levels were markedly elevated in the HS groups. Tumor necrosis factor-alpha and interleukin-6 levels were similar between the control and HS groups but significantly higher in the LR group (P < .05). The lung injury score was significantly higher in the LR group compared with the 7.5% HS and 3% HS groups (5.7 +/- 0.7, 2.1 +/- 0.4, and 2.7 +/- 0.5, respectively). Intestinal injury was attenuated in the 7.5% HS and 3% HS groups compared with the LR group (2.0 +/- 0.6, 2.3 +/- 0.4, and 5.9 +/- 0.6, respectively). CONCLUSIONS: A small-volume resuscitation strategy modulates the inflammatory response and decreases end-organ damage after HS. Three percent HS provides immunomodulatory and metabolic effects similar to those observed with conventional concentrations of HS. (C) 2009 Elsevier Inc. All rights reserved.

2.3 Million Americans are “Long-Distance Caregivers” for people with Alzheimer’s; Costs for Long-Distance Caregivers are Almost Twice as High.According to the Alzheimer's Association 2013 Alzheimer's Disease Facts and Figures report released today, one in three seniors dies with Alzheimer’s or another dementia in the United States. The new report shows that while deaths from other major diseases, such as heart disease, HIV/AIDS and stroke, continue to experience significant declines, Alzheimer’s deaths continue to rise — increasing 68 percent from 2000-2010.��“Unfortunately, today there are no Alzheimer’s survivors. If you have Alzheimer's disease, you either die from it or diewith it,” said Harry Johns, president and CEO of the Alzheimer’s Association. “Now we know that 1 in 3 seniors dies with Alzheimer’s disease or another dementia. Urgent, meaningful��action is necessary, particularly as more and more people age into greater risk for developing a disease��that today has no cure and no way to slow or stop its progression.”Read more here.����������

We tested the hypothesis that elevation in heart rate (HR) during submaximal exercise in the heat is related, in part, to increased percentage of maximal O(2) uptake (%Vo(2 max)) utilized due to reduced maximal O(2) uptake (Vo(2 max)) measured after exercise under the same thermal conditions. Peak O(2) uptake (Vo(2 peak)), O(2) uptake, and HR during submaximal exercise were measured in 22 male and female runners under four environmental conditions designed to manipulate HR during submaximal exercise and Vo(2 peak). The conditions involved walking for 20 min at approximately 33% of control Vo(2 max) in 25, 35, 40, and 45 degrees C followed immediately by measurement of Vo(2 peak) in the same thermal environment. Vo(2 peak) decreased progressively (3.77 +/- 0.19, 3.61 +/- 0.18, 3.44 +/- 0.17, and 3.13 +/- 0.16 l/min) and HR at the end of the submaximal exercise increased progressively (107 +/- 2, 112 +/- 2, 120 +/- 2, and 137 +/- 2 beats/min) with increasing ambient temperature (T(a)). HR and %Vo(2 peak) increased in an identical fashion with increasing T(a). We conclude that elevation in HR during submaximal exercise in the heat is related, in part, to the increase in %Vo(2 peak) utilized, which is caused by reduced Vo(2 peak) measured during exercise in the heat. At high T(a), the dissociation of HR from %Vo(2 peak) measured after sustained submaximal exercise is less than if Vo(2 max) is assumed to be unchanged during exercise in the heat.
