Carbon Tax and Shift: How to make it work for Oregon\u27s Economy.

This study analyzes a carbon tax and tax shift in Oregon as a means of reducing market inefficiencies by placing a meaningful price on carbon emissions. This study shows that a carbon tax can reduce distortionary income taxes, and provide new revenue opportunities for Oregon. By taxing carbon emissions and reducing Corporate and Personal Income tax rates, Oregon can reduce the negative incentives created by income taxes while generating revenue and reducing carbon emissions. The report shows that putting a price on carbon in Oregon can result in reductions in harmful emissions and have positive impacts on the economy

Presença de espécies de Paragonimus em crustáceos hospedeiros secundários em Bogotá, Colômbia

ABSTRACT: Paragonimus spp. are trematode parasites that infect human populations worldwide. It is believed that infection rates within Asia reach five to ten percent of the total population. Three of the largest areas of possible infection are Asia, Central and South America as well as Africa, where the total population at risk is estimated to be 293 million people. Humans are infected via ingestion of raw or undercooked decapod crustaceans. Objective: To identify the presence of Paragonimus spp. in crabs from Bogotá, Colombia. Methods: The native crab Neostrengeria macropa and the aquatic invasive crayfish Procambarus clarkii in Bogotá, Colombia, were collected from local markets, pet stores and waterways and dissected to assess the presence of Paragonimus spp. Results: The native crab species, N. macropa (n=29) had an infection prevalence of 17.2%, while the invasive crayfish species, P. clarkii (n=22), had a prevalence of 36.4% combined from both field captured animals and purchased samples. Conclusion: Although the estimated prevalence is lower compared to previous studies in other cities of Colombia, Paragonimus represent a risk to human health. Several environmental factors may contribute to the difference in prevalence including collecting season, rainfall, temperature, altitude and the El Niño Southern Oscillation.RESUMEN: Antecedentes. Los Paragonimus spp. constituyen un grupo de parásitos tremátodos que infectan a humanos en todo el mundo. Se considera que entre 5 y 10% de la población humana de Asia está infectada. Las áreas con mayor posibilidad de infección son Asia, Centro y Sur América, así como África. Se estima que 293 millones de personas están en riesgo de infección. Los humanos se pueden infectar al consumir crustáceos decápodos crudos. Objetivo: Identificar la presencia de Paragonimus spp. en crustáceos en Bogotá, Colombia. Métodos: Una muestra de cangrejos nativos Neostrengeria macropa y de decápodos invasores Procambarus clarkii fue colectada tanto en mercados locales de Bogotá, como en tiendas de mascotas, ríos, y quebradas. Posteriormente fueron diseccionados para detectar la presencia de Paragonimus spp. Resultados: La prevalencia de la infección en N. macropa (n=29) fue de 17,2%, y en la especie invasora, P. clarkii (n=22), fue de 36,4% (porcentaje combinado de los animales colectados en el campo y los comprados en tiendas). Conclusión: Aunque la prevalencia en este estudio fue más baja que la de otras investigaciones relacionadas, se considera que existe riesgo para la salud humana. Es probable que algunos factores medio ambientales hayan contribuido a la diferencia, incluyendo: temporada de colecta, nivel de lluvias, temperatura, altura, y el fenómeno El Niño.RESUMO: Antecedentes. Paragonimus spp. são trematódeos parasitas que infectam populações humanas ao redor do mundo. Acredita-se que as taxas de infecção na Ásia atingem de 5 a 10% da população. As três maiores áreas de infecção se localizam na Ásia, Américas do Sul e Central e África, onde a população total em risco é estimada em 293 milhões de pessoas. Os humanos são infectados pela ingestão de crustáceos decápodes crus ou mal cozidos. Objetivo: Identificar a presença de Paragonimus spp. em Bogotá, Colômbia. Métodos: Indivíduos de caranguejo nativo Neostrengeria macropa e lagostim aquático invasivo Procambarus clarkii foram coletados em mercados locais, lojas de animais de estimação e cursos de água em Bogotá (Colômbia) e posteriormente dissecados para verificação da presença de Paragonimus spp. Resultados: A espécie de caranguejo nativa N. macropa (n=29) apresentou prevalência de infecção de 17,2%, enquanto a espécie de lagostim invasivo, P. clarkii (n=22), apresentou prevalência de 36,4%, quando combinados os animais capturados em campo e os animais comprados. Conclusão: Embora a prevalência estimada neste estudo foi menor do que a de pesquisas anteriores realizadas em outras cidades da Colômbia, existe um risco para a saúde humana. Há inúmeros fatores ambientais que podem contribuir para a diferença de prevalência, dentre eles: a estação em que a coleta foi realizada, pouca precipitação, temperatura, altitude e a Oscilação Sul-El Niño

Integrating ‘e’ and ‘p’: Building a new approval infrastructure

eBooks are becoming a preferred format for many libraries; however, acquiring eBooks on an approval plan can be challenging. This presentation will discuss how two university libraries have partnered with approval plan vendors to integrate “e” (eBook) and “p” (print book) acquisition into approval profiles. Presenters will describe the challenges of managing eBook selection and acquisition, discuss how libraries and approval vendors deal with evolving publishing patterns, and suggest strategies for acquiring eBooks as a preferred format

Palynological, geochemical, and mineralogical characteristics of the Early Jurassic Liasidium Event in the Cleveland Basin, Yorkshire, UK

A previously proposed hyperthermal episode in the Early Jurassic (mid-Sinemurian) is investigated from the shallow marine succession at Robin Hood’s Bay, Cleveland Basin, Yorkshire, UK. Palynological study confirms that the stratigraphical extent of the distinctive dinoflagellate cyst Liasidium variabile corresponds very closely to the oxynotum Zone. The range of Liasidium variabile also corresponds to an overall negative excursion in carbon-isotopes measured in bulk organic matter, which here exhibits a double spike in the middle oxynotum Zone. Additionally, Liasidium variabile abundances track overall transgressive-regressive facies trends with peak abundance of dinoflagellate cysts corresponding to deepest water facies and maximum flooding. Lithological cycles (parasequences), defined by visual description and hand-held X-ray fluorescence analysis of powdered samples, match previously suggested short eccentricity cycles, and allow a total duration for the event of at least one million years to be suggested. Changes in clay mineralogy throughout the section determined by whole rock X-ray diffraction and scanning electron microscopy are shown to be largely related to authigenic processes, and neither support nor refute the proposition of coeval palaeoclimate changes. The combined characteristics of the Liasidium Event described from Robin Hood’s Bay are similar to, but much less extreme than, the Early Jurassic Toarcian Oceanic Anoxic Event albeit, at this locality, there is no evidence for the development of significant bottom water deoxygenation

OPA1 disease alleles causing dominant optic atrophy have defects in cardiolipin-stimulated GTP hydrolysis and membrane tubulation

The dynamin-related GTPase OPA1 is mutated in autosomal dominant optic atrophy (DOA) (Kjer type), an inherited neuropathy of the retinal ganglion cells. OPA1 is essential for the fusion of the inner mitochondrial membranes, but its mechanism of action remains poorly understood. Here we show that OPA1 has a low basal rate of GTP hydrolysis that is dramatically enhanced by association with liposomes containing negative phospholipids such as cardiolipin. Lipid association triggers assembly of OPA1 into higher order oligomers. In addition, we find that OPA1 can promote the protrusion of lipid tubules from the surface of cardiolipin-containing liposomes. In such lipid protrusions, OPA1 assemblies are observed on the outside of the lipid tubule surface, a protein-membrane topology similar to that of classical dynamins. The membrane tubulation activity of OPA1 is suppressed by GTPγS. OPA1 disease alleles associated with DOA display selective defects in several activities, including cardiolipin association, GTP hydrolysis and membrane tubulation. These findings indicate that interaction of OPA1 with membranes can stimulate higher order assembly, enhance GTP hydrolysis and lead to membrane deformation into tubules

Benefits and resource implications of family meetings for hospitalized palliative care patients: research protocol.

BACKGROUND:Palliative care focuses on supporting patients diagnosed with advanced, incurable disease; it is 'family centered', with the patient and their family (the unit of care) being core to all its endeavours. However, approximately 30-50% of carers experience psychological distress which is typically under recognised and consequently not addressed. Family meetings (FM) are recommended as a means whereby health professionals, together with family carers and patients discuss psychosocial issues and plan care; however there is minimal empirical research to determine the net effect of these meetings and the resources required to implement them systematically. The aims of this study were to evaluate: (1) if family carers of hospitalised patients with advanced disease (referred to a specialist palliative care in-patient setting or palliative care consultancy service) who receive a FM report significantly lower psychological distress (primary outcome), fewer unmet needs, increased quality of life and feel more prepared for the caregiving role; (2) if patients who receive the FM experience appropriate quality of end-of-life care, as demonstrated by fewer hospital admissions, fewer emergency department presentations, fewer intensive care unit hours, less chemotherapy treatment (in last 30 days of life), and higher likelihood of death in the place of their choice and access to supportive care services; (3) the optimal time point to deliver FM and; (4) to determine the cost-benefit and resource implications of implementing FM meetings into routine practice.METHODS:Cluster type trial design with two way randomization for aims 1-3 and health economic modeling and qualitative interviews with health for professionals for aim 4.DISCUSSION:The research will determine whether FMs have positive practical and psychological impacts on the family, impacts on health service usage, and financial benefits to the health care sector. This study will also provide clear guidance on appropriate timing in the disease/care trajectory to provide a family meeting.<br/

A soft selective sweep during rapid evolution of gentle behaviour in an Africanized honeybee

Africanized honey bees (AHB) are notoriously aggressive, but in Puerto Rico they have a ‘gentle’ phenotype. Here, Avalos et al. show that there has been a soft selective sweep at several loci in the Puerto Rican AHB population and suggest a role in the rapid evolution of gentle behaviour

Physiological effects of major genes affecting ovulation rate in sheep

Genetic mutations with major effects on ovulation rate in sheep were recently identified in two genes of the transforming growth factor (TGFβ) superfamily and a TGFβ receptor, namely bone morphogenetic protein 15 (BMP15), otherwise known as the growth differentiation factor 9b (GDF9b), GDF9 and activin-like kinase 6 (ALK6) otherwise known as the BMP receptor type IB (BMPRIB). Animals homozygous for the BMP15 or GDF9 mutations are anovulatory whereas animals heterozygous for BMP15 or GDF9 or heterozygous or homozygous for ALK6 have higher than normal ovulation rates. Immunisation of ewes against BMP15 or GDF9 shows that both are essential for normal follicular development and control of ovulation rate. Common features of fertile animals with the BMP15, ALK6 (and possibly GDF9) mutations are changes in oocyte development during early preantral follicular growth, earlier maturation of granulosa cells and ovulation of mature follicles at smaller diameters. In summary, these findings have led to a new paradigm in reproductive biology, namely that the oocyte plays a key role in regulating the ovulation rate
