The feasibility of neuroimaging methods in marketing research

On July 17, 1990, President George Bush ssued “Proclamation #6158" which boldly declared the following ten years would be called the “Decade of the Brain” (Bush, 1990). Accordingly, the research mandates of all US federal biomedical institutions worldwide were redirected towards the study of the brain in general and cognitive neuroscience specifically. In 2008, one of the greatest legacies of this “Decade of the Brain” is the impressive array of techniques that can be used to study cortical activity. We now stand at a juncture where cognitive function can be mapped in the time, space and frequency domains, as and when such activity occurs. These advanced techniques have led to discoveries in many fields of research and clinical science, including psychology and psychiatry. Unfortunately, neuroscientific techniques have yet to be enthusiastically adopted by the social sciences. Market researchers, as specialized social scientists, have an unparalleled opportunity to adopt cognitive neuroscientific techniques and significantly redefine the field and possibly even cause substantial dislocations in business models. Following from this is a significant opportunity for more commercially-oriented researchers to employ such techniques in their own offerings. This report examines the feasibility of these techniques.

Precompetitive data sharing as a catalyst to address unmet needs in Parkinson's disease

Parkinson's disease is a complex heterogeneous disorder with urgent need for disease-modifying therapies. Progress in successful therapeutic approaches for PD will require an unprecedented level of collaboration. At a workshop hosted by Parkinson's UK and co-organized by Critical Path Institute's (C-Path) Coalition Against Major Diseases (CAMD) Consortiums, investigators from industry, academia, government and regulatory agencies agreed on the need for sharing of data to enable future success. Government agencies included EMA, FDA, NINDS/NIH and IMI (Innovative Medicines Initiative). Emerging discoveries in new biomarkers and genetic endophenotypes are contributing to our understanding of the underlying pathophysiology of PD. In parallel there is growing recognition that early intervention will be key for successful treatments aimed at disease modification. At present, there is a lack of a comprehensive understanding of disease progression and the many factors that contribute to disease progression heterogeneity. Novel therapeutic targets and trial designs that incorporate existing and new biomarkers to evaluate drug effects independently and in combination are required. The integration of robust clinical data sets is viewed as a powerful approach to hasten medical discovery and therapies, as is being realized across diverse disease conditions employing big data analytics for healthcare. The application of lessons learned from parallel efforts is critical to identify barriers and enable a viable path forward. A roadmap is presented for a regulatory, academic, industry and advocacy driven integrated initiative that aims to facilitate and streamline new drug trials and registrations in Parkinson's disease.

Cardiac Neural Crest Cells and Their Role in Murine Purkinje Fiber Development

The heart beat is regulated by the cardiac conduction system (CCS), a specialized group of cells that transmit electrical impulses around the heart chambers. During development, ventricular CCS cells originate from embryonic cardiomyocytes and not from the neural crest. Nonetheless, discoveries in chick implied that the cardiac neural crest (CNC) cells contribute to proper development of the ventricular CCS. In this report, the Splotch mouse mutant (Pax3sp), in which the CNC cells do not migrate to the heart, was used to investigate whether these cells also affect proper CCS development in mammals. Homozygote mutants (Pax3Sp!Sp) are lethal on 111 Embryonic Day 13 (E13), and can be phenotyped by spina bifida and exencephaly. Pax3Spi+ mice were crossed to obtain wild type, Pax3 Spi+ and Pax3 Sp!Sp embryos. Comparison of hematoxylin and eosin stained histological sections showed less trabeculation in El2.5 cardiac ventricles of Pax3Sp!Sp. Furthermore, immunofluorescence analysis with the Purkinje fiber marker Cx40 showed a qualitative difference between wild type and mutant hearts. Quantitative analysis indicated that Pax3 Sp!Sp ventricles had fewer Cx40 expressing cells, as well as less Cx40 being expressed per cell when compared to wild type ventricles. Immunofluorescence with the H3 histome mitosis antibody showed fewer proliferating cells in the ventricles of mutant embryos when compared to controls. These results suggest that CNCC affect the morphogenesis of cardiac ventricles and the development of the ventricular CCS by contributing cellular proliferation.

A suite of global, cross-scale topographic variables for environmental and biodiversity modeling, links to files in GeoTIFF format

Topographic variation, the spatial variation in elevation and terrain features, underpins a myriad of patterns and processes in geography and ecology and is key to understanding the variation of life on the planet. The characterization of this variation is scale-dependent, i.e. it varies with the distance over which features are assessed and with the spatial grain (grid cell resolution) of analysis. A fully standardized and global multivariate product of different terrain features has the potential to support many large-scale basic research and analytical applications, however to date, such technique is unavailable. Here we used the digital elevation model products of global 250 m GMTED and near-global 90 m SRTM to derive a suite of topographic variables: elevation, slope, aspect, eastness, northness, roughness, terrain roughness index, topographic position index, vector ruggedness measure, profile and tangential curvature, and 10 geomorphological landform classes. We aggregated each variable to 1, 5, 10, 50 and 100 km spatial grains using several aggregation approaches (median, average, minimum, maximum, standard deviation, percent cover, count, majority, Shannon Index, entropy, uniformity). While a global cross-correlation underlines the high similarity of many variables, a more detailed view in four mountain regions reveals local differences, as well as scale variations in the aggregated variables at different spatial grains. All newly-developed variables are available for download at http://www.earthenv.org and can serve as a basis for standardized hydrological, environmental and biodiversity modeling at a global extent.

Essays on Firm Heterogeneity with Empirical Applications in Economic History and Agricultural Economics

This thesis uses models of firm-heterogeneity to complete empirical analyses in economic history and agricultural economics. In Chapter 2, a theoretical model of firm heterogeneity is used to derive a statistic that summarizes the welfare gains from the introduction of a new technology. The empirical application considers the use of mechanical steam power in the Canadian manufacturing sector during the late nineteenth century. I exploit exogenous variation in geography to estimate several parameters of the model. My results indicate that the use of steam power resulted in a 15.1 percent increase in firm-level productivity and a 3.0-5.2 percent increase in aggregate welfare. Chapter 3 considers various policy alternatives to price ceiling legislation in the market for production quotas in the dairy farming sector in Quebec. I develop a dynamic model of the demand for quotas with farmers that are heterogeneous in their marginal cost of milk production. The econometric analysis uses farm-level data and estimates a parameter of the theoretical model that is required for the counterfactual experiments. The results indicate that the price of quotas could be reduced to the ceiling price through a 4.16 percent expansion of the aggregate supply of quotas, or through moderate trade liberalization of Canadian dairy products. In Chapter 4, I study the relationship between farm-level productivity and participation in the Commercial Export Milk (CEM) program. I use a difference-in-difference research design with inverse propensity weights to test for causality between participation in the CEM program and total factor productivity (TFP). I find a positive correlation between participation in the CEM program and TFP, however I find no statistically significant evidence that the CEM program affected TFP.

Key Questions in Marine Megafauna Movement Ecology

It is a golden age for animal movement studies and so an opportune time to assess priorities for future work. We assembled 40 experts to identify key questions in this field, focussing on marine megafauna, which include a broad range of birds, mammals, reptiles, and fish. Research on these taxa has both underpinned many of the recent technical developments and led to fundamental discoveries in the field. We show that the questions have broad applicability to other taxa, including terrestrial animals, flying insects, and swimming invertebrates, and, as such, this exercise provides a useful roadmap for targeted deployments and data syntheses that should advance the field of movement ecology.

Non-thermal phenomena in galaxy clusters: the LOFAR revolution

Turbulence introduced into the intra-cluster medium (ICM) through cluster merger events transfers energy to non-thermal components (relativistic particles and magnetic fields) and can trigger the formation of diffuse synchrotron radio sources. Owing to their steep synchrotron spectral index, such diffuse sources can be better studied at low radio frequencies. In this respect, the LOw Frequency ARray (LOFAR) is revolutionizing our knowledge thanks to its unprecedented resolution and sensitivity below 200 MHz. In this Thesis we focus on the study of radio halos (RHs) by using LOFAR data. In the first part of this work we analyzed the largest-ever sample of galaxy clusters observed at radio frequencies. This includes 309 Planck clusters from the Second Data Release of the LOFAR Two Metre Sky Survey (LoTSS-DR2), which span previously unexplored ranges of mass and redshift. We detected 83 RHs, half of which being new discoveries. In 140 clusters we lack a detected RH; for this sub-sample we developed new techniques to derive upper limits to their radio powers. By comparing detections and upper limits, we carried out the first statistical analysis of populations of clusters observed at low frequencies and tested theoretical formation models. In the second part of this Thesis we focused on ultra-steep spectrum radio halos. These sources are almost undetected at GHz frequencies, but are thought to be common at low frequencies. We presented LOFAR observations of two interesting clusters hosting ultra-steep spectrum radio halos. With complementary radio and X-ray observations we constrained the properties and origin of these targets.

O papel da cidade de Viçosa-MG na rede urbana : a especialização funcional de uma cidade média mineira

Rede é o nome dado para se referenciar qualquer forma que seja composta por linhas interligadas por pontos, sendo assim essa denominação é utilizada para participar de nomes e conceitos em diversas área do conhecimento. Na geografia isso não ocorre de forma diferente. As redes geográficas são a denominação dada as ligações feitas no espaço articuladas por pontos, notadamente são usadas para se fazer referência a redes materiais, mas podem ser mais imateriais ou abstratas a depender do objeto de pesquisa e do adjetivo adotado. A noção de redes urbanas nasceu vinculada aos objetos materiais, entretanto com a evolução da técnica passou a abranger objetos cada vez mais virtuais. As redes urbanas são compostas pelo conjunto de cidades, cada qual com sua centralidade representadas por pontos ou nós na rede, e pelas ligações entre elas, rodovias, hidrovias, infovias etc. As cidades que compõem a rede, por mais semelhanças que possam ter entre si, tem diferentes tipos e graus de centralidade, de poder de atração de pessoas, de recursos; sendo uma região de influência singular, que muda de tempos em tempos, face a evolução do território onde se insere. Tanto as centralidades quanto as redes de urbanas estão em constante mudança, necessitando sempre de atualização tornando o estudo das redes e das centralidades uma questão sempre nova; em especial quando considerado um território tão vasto e complexo como o brasileiro. Neste trabalho relatamos os resultados do estudo das especificidades da centralidade da cidade de Viçosa, que está localizada no interior do estado de Minas Gerais, Brasil. Este estudo fez uso de dados numéricos, fotográficos e cartográficos coletados em diversos momentos da evolução do município e da região onde este se insere, que revelaram as mudanças de qualidade e de intensidade na centralidade dessa cidade, hoje tipificada como média ou intermediária, inserida na rede urbana mineira. No período compreendido entre os anos de 1850 e 1930, Viçosa passou de uma inexpressiva localidade rural, a importante centro de produção de café, galgando ganhos políticos nesse período. Seguiu-se um período de menor pujança, por cerca de setenta anos, para depois, na virada do século XX para XXI, ressurgi como uma localidade especializada em oferecer serviços, notadamente vinculados ao ensino superior e à produção de ciência e tecnologia. Essa nova centralidade, ao contrário do que muitas vezes ocorre, não foi fruto nem de um recurso natural inerente ao território e nem, tão pouco, pela atuação de grandes grupos capitalistas. Foi galgado principalmente pela atuação do Estado que construiu ali as bases de uma especialização funcional, através da implantação de uma universidade pública.

Territórios ocupados : uma abordagem geográfica do conflito israelo-palestino através dos quadrinhos de Joe Sacco

O estudo trata da dimensão territorial do conflito israelo-palestino a partir do jornalismo em quadrinhos produzidos por Joe Sacco. Para isso, procura, preliminarmente, desenvolver uma abordagem da representação espacial nos quadrinhos através de sua linguagem visual e textual, que evidencia uma percepção espacial e expressa um conjunto de significados a partir das ações que unem os personagens ao lugar. A partir desse quadro de interpretação, o presente estudo focaliza, através da análise das obras de Joe Sacco, o conflito árabe-israelense para entender os territórios palestinos ocupados como um volume político que retrata a perda de soberania política dos palestinos em sentido amplo. Esse enfoque se volta para uma reflexão a respeito do dia a dia dos palestinos através dos quadrinhos considerando o cotidiano da ocupação e sua dimensão espacial (ou seja, um conteúdo que remete ao território, uma vez que apresenta todo um conjunto de significados que evocam um sentido territorial). Assim, a pesquisa objetiva entender os territórios palestinos ocupados, procurando evidenciar em que medida os quadrinhos de Joe Sacco disponibilizam elementos para a pesquisa em Geografia, na medida em que expressam, sugere-se, uma geograficidade. Tal enfoque, que recorre ao escopo conceitual da Geografia – e notadamente ao conceito de território e seus múltiplos –, mediatizando-os através do recurso às obras de Joe Sacco, possibilita, sugere-se, um ângulo de abordagem peculiar sobre o território em locais de conflito, na medida em que, através dele, torna-se possível observar as formas de controle e precarização territorial dos palestinos em sua formação espaço-territorial.

Potenciais evocados auditivos de média latência em adultos com epilepsia

Introdução Os potenciais evocados auditivos de média latência (PEAML) reflectem actividade neuronal mesencefáfica, mais precisamente da região tálamo-cortical, dos colículos inferiores e da formação reticular. A epilepsia é caracterizada por variadas manifestações anormais do comportamento cerebral, sendo descrita como uma perturbação da função cerebral, tendo origem numa descarga anómala de um conjunto ou da totalidade dos neurónios do córtice cerebral. Está documentado, que as descargas eléctricas provocadas pelas crises de epilepsia podem levar a perdas neuronais, pelo que poderão existir alterações nos PEAML. Objectivos A escassa existência de literatura sobre o tema e a não investigação na população portuguesa, originou a execução deste estudo, que teve como objectivo investigar e documentar a existência de alterações ou achados nos componentes neuronais de média latência (PEAML), numa amostra de portugueses com epilepsia. Metodologia Foram realizados PEAML a um grupo de controlo (GC) composto por 16 participantes e a um grupo clínico (GCL) de 8 participantes com epilepsia, sendo analisados os componentes Na, Pa e Na-Pa quanto à sua morfologia, latência e amplitude. Resultados A morfologia das ondas e a presença de epilepsia não estão associados, no entanto, contrariamente ao GC que evidenciou latências e amplitudes de Na, Pa e Na-Pa dentro dos padrões de normalidade, a alteração ou ausência de respostas por parte do GCL é significativa na totalidade das medidas investigadas. Conclusão Em epilepsias generalizadas e focais do lobo temporal os PEAML evidenciam alterações, tal achado poderá ser eventualmente justificado pela propagação ascendente e descendente da informação auditiva se encontrar comprometida, devido a sequelas deixadas pelas crises epilépticas nas vias auditivas mesencefálicas. As alterações verificadas foram uma morfologia anómala das ondas ou ausência das mesmas.

A indústria de defesa na cooperação Brasil-Portugal

The global dynamics of alliances are strongly determined by the level of cooperation among states. This cooperation can be embodied in various aspects, but the level of defense and security cooperation becomes usually more doctrinal and lasting. By the nature of sovereignty that instills in the bilateral relationship, cooperation at defense and security level can leverages other forms of cooperation. The circumstances and relational balance between Brazil and Portugal seem to evolve towards distancing opportunities, despite they are culturally and institutionally untainted. The economic dynamics, the strategic projection in global sustainability terms, the scale and ambition of Brazilian regional leadership, contrasts with the actual context of Portugal, distancing himself both on the stage where they operate. On the other hand, the historical and cultural roots, the language, the affinity of the peoples of CPLP and some opportunities for economic niches, trend to attract both countries. The condition of Portugal in NATO and Europe, coupled with the ability to export technical and human resources to value-added for Brazil, seems also to become approaching factors. On the balance of these dynamics, there is a set of exogenous factors (economic, external global relations matrix, regional stability, among others), which are not always controlled by any of both countries. These factors call for strong capacity for foresight analysis and decision making, with the inherent risk. There is cooperation vectors that are not apparently penalized by geographic distance, or by the difference of realities. Among these vectors we shall highlight synergies in technological niches, highly tradable goods and, mostly, using the domain of dual technologies. The thirteen niches herein identified are: Monitoring, Navigation, Command and Control, Electronics, Optoelectronics, Communication and remote sensing, Information Technologies, Flight Simulation, Specialized Training, Fiber Optic Sensors, Materials Engineering, Nanotechnology and Communications. Cumulating with identified opportunities in traditional relational framework, both countries are growing (in geography and economic terms) into the Atlantic, making it a central element in the bilateral approach. By being at the same time a growing stage of disputes and which stability tends to be threatened, it will be done an analysis of these synergistic vectors, superimposed on the impact on Atlantic securitization process.
