SPARC Data Initiative: Comparison of water vapor climatologies from international satellite limb sounders

Within the SPARC Data Initiative, the first comprehensive assessment of the quality of 13 water vapor products from 11 limb-viewing satellite instruments (LIMS, SAGE II, UARS-MLS, HALOE, POAM III, SMR, SAGE III, MIPAS, SCIAMACHY, ACE-FTS, and Aura-MLS) obtained within the time period 1978-2010 has been performed. Each instrument's water vapor profile measurements were compiled into monthly zonal mean time series on a common latitude-pressure grid. These time series serve as basis for the "climatological" validation approach used within the project. The evaluations include comparisons of monthly or annual zonal mean cross sections and seasonal cycles in the tropical and extratropical upper troposphere and lower stratosphere averaged over one or more years, comparisons of interannual variability, and a study of the time evolution of physical features in water vapor such as the tropical tape recorder and polar vortex dehydration. Our knowledge of the atmospheric mean state in water vapor is best in the lower and middle stratosphere of the tropics and midlatitudes, with a relative uncertainty of. 2-6% (as quantified by the standard deviation of the instruments' multiannual means). The uncertainty increases toward the polar regions (+/- 10-15%), the mesosphere (+/- 15%), and the upper troposphere/lower stratosphere below 100 hPa (+/- 30-50%), where sampling issues add uncertainty due to large gradients and high natural variability in water vapor. The minimum found in multiannual (1998-2008) mean water vapor in the tropical lower stratosphere is 3.5 ppmv (+/- 14%), with slightly larger uncertainties for monthly mean values. The frequently used HALOE water vapor data set shows consistently lower values than most other data sets throughout the atmosphere, with increasing deviations from the multi-instrument mean below 100 hPa in both the tropics and extratropics. The knowledge gained from these comparisons and regarding the quality of the individual data sets in different regions of the atmosphere will help to improve model-measurement comparisons (e.g., for diagnostics such as the tropical tape recorder or seasonal cycles), data merging activities, and studies of climate variability.

SPARC Data Initiative: A comparison of ozone climatologies from international satellite limb sounders

A comprehensive quality assessment of the ozone products from 18 limb-viewing satellite instruments is provided by means of a detailed intercomparison. The ozone climatologies in form of monthly zonal mean time series covering the upper troposphere to lower mesosphere are obtained from LIMS, SAGE I/II/III, UARS-MLS, HALOE, POAM II/III, SMR, OSIRIS, MIPAS, GOMOS, SCIAMACHY, ACE-FTS, ACE-MAESTRO, Aura-MLS, HIRDLS, and SMILES within 1978–2010. The intercomparisons focus on mean biases of annual zonal mean fields, interannual variability, and seasonal cycles. Additionally, the physical consistency of the data is tested through diagnostics of the quasi-biennial oscillation and Antarctic ozone hole. The comprehensive evaluations reveal that the uncertainty in our knowledge of the atmospheric ozone mean state is smallest in the tropical and midlatitude middle stratosphere with a 1σ multi-instrument spread of less than ±5%. While the overall agreement among the climatological data sets is very good for large parts of the stratosphere, individual discrepancies have been identified, including unrealistic month-to-month fluctuations, large biases in particular atmospheric regions, or inconsistencies in the seasonal cycle. Notable differences between the data sets exist in the tropical lower stratosphere (with a spread of ±30%) and at high latitudes (±15%). In particular, large relative differences are identified in the Antarctic during the time of the ozone hole, with a spread between the monthly zonal mean fields of ±50%. The evaluations provide guidance on what data sets are the most reliable for applications such as studies of ozone variability, model-measurement comparisons, detection of long-term trends, and data-merging activities.

A method for merging nadir-sounding climate records, with an application to the global-mean stratospheric temperature data sets from SSU and AMSU

A method is proposed for merging different nadir-sounding climate data records using measurements from high-resolution limb sounders to provide a transfer function between the different nadir measurements. The two nadir-sounding records need not be overlapping so long as the limb-sounding record bridges between them. The method is applied to global-mean stratospheric temperatures from the NOAA Climate Data Records based on the Stratospheric Sounding Unit (SSU) and the Advanced Microwave Sounding Unit-A (AMSU), extending the SSU record forward in time to yield a continuous data set from 1979 to present, and providing a simple framework for extending the SSU record into the future using AMSU. SSU and AMSU are bridged using temperature measurements from the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS), which is of high enough vertical resolution to accurately represent the weighting functions of both SSU and AMSU. For this application, a purely statistical approach is not viable since the different nadir channels are not sufficiently linearly independent, statistically speaking. The near-global-mean linear temperature trends for extended SSU for 1980–2012 are −0.63 ± 0.13, −0.71 ± 0.15 and −0.80 ± 0.17 K decade−1 (95 % confidence) for channels 1, 2 and 3, respectively. The extended SSU temperature changes are in good agreement with those from the Microwave Limb Sounder (MLS) on the Aura satellite, with both exhibiting a cooling trend of ~ 0.6 ± 0.3 K decade−1 in the upper stratosphere from 2004 to 2012. The extended SSU record is found to be in agreement with high-top coupled atmosphere–ocean models over the 1980–2012 period, including the continued cooling over the first decade of the 21st century.

Climatology and variability of trace gases in extratropical double-tropopause regions from MLS, HIRDLS, and ACE-FTS measurements

Upper tropospheric and lower stratospheric measurements from the Aura Microwave Limb Sounder (MLS), the Aura High Resolution Dynamics Limb Sounder (HIRDLS), and the Atmospheric Chemistry Experiment-Fourier transform spectrometer (ACE-FTS) are used to present the first global climatological comparison of extratropical, nonpolar trace gas distributions in double-tropopause (DT) and single-tropopause (ST) regions. Stratospheric tracers, O3, HNO3, and HCl, have lower mixing ratios ∼2–8 km above the primary (lowermost) tropopause in DT than in ST regions in all seasons, with maximum Northern Hemisphere (NH) differences near 50% in winter and 30% in summer. Southern Hemisphere winter differences are somewhat smaller, but summer differences are similar in the two hemispheres. H2O in DT regions of both hemispheres shows strong negative anomalies in November through February and positive anomalies in July through October, reflecting the strong seasonal cycle in H2O near the tropical tropopause. CO and other tropospheric tracers examined have higher DT than ST values 2–7 km above the primary tropopause, with the largest differences in winter. Large DT-ST differences extend to high NH latitudes in fall and winter, with longitudinal maxima in regions associated with enhanced wave activity and subtropical jet variations. Results for O3 and HNO3 agree closely between MLS and HIRDLS, and differences from ACE-FTS are consistent with its sparse and irregular midlatitude sampling. Consistent signatures in climatological trace gas fields provide strong evidence that transport from the tropical upper troposphere into the layer between double tropopauses is an important pathway for stratosphere-troposphere exchange.

Making: the invisible visible

In this book essay I argue that modern and contemporary works of art (i.e. paintings, photographs, films, and videos) really ought to retrieve something of their auratic-character, which turns the physical toward the metaphysical, the material toward the immaterial, the visible toward the invisible - making artworks, ‘things among things, something other than [a] thing’ (Theodor W. Adorno, Aesthetic Theory, 86). There is, perhaps, an aura to art or art is a medium or a conduit or a technology for rediscovering and reproducing aura, which makes it something other than a mere thing. Such works of art are constitutively enigmatic, a certain form of magic making: they (re-)distribute the visible and the invisible, they (re-)configure appearance and disappearance. Such works of art may become visual events, which begin an education in and through (dis-)appearances. To achieve this end, I detail Theodor W. Adorno’s and Walter Benjamin’s respective theories of (art’s) aura in the age of technological reproducibility, which I relate to Jacques Rancière’s more recent discussion of the ‘pensive image,’ and I focus my reading on a number of works by Susan Hiller (photographs), John Constable (paintings), Alfred Stieglitz (photographs), and Tacita Dean (photograph and 16mm film).

Théâtre du Grand-Guignol : Les mécanismes de la peur dans deux pièces du théâtre médical d’André de Lorde et Alfred BinetL’Obsession et Une leçon à la Salpêtrière .

Le Grand-Guignol n’a reçu que peu d’attention critique sérieuse jusqu’à la fin des années 1980. Ce petit théâtre a pendant 65 ans, de 1897 à 1962, offert des pièces d’un genre nouveau mêlant terreur, violence et souvent érotisme. Le succès était au rendez-vous et le Théâtre du Grand-Guignol est longtemps resté une attraction incontournable de Paris. Les pièces choisies pour ce mémoire sont issues de ce répertoire et ont cela de particulier qu’elles ont été écrites en collaboration entre un écrivain, André de Lorde, et un psychologue, Alfred Binet. Malgré leurs différences, ces pièces ont une constante, un point commun : elles suscitent toutes la peur chez le spectateur. C’est précisément la façon dont Binet et de Lorde établissent cette peur à travers leurs pièces qui sera l’objet d’étude de ce mémoire. Ce mémoire se limite à l’analyse de deux œuvres en particulier : L’Obsession, et Une leçon à la Salpêtrière. Appréhender la notion de peur dans une œuvre théâtrale impose de réfléchir non seulement aux thèmes développés mais également à la construction dramatique du récit et à sa mise en scène. Dans le cas spécifique d’une pièce Grand-Guignol, il y aura une dimension supplémentaire à inclure : ce que l’on peut appeler « l’expérience Grand-Guignol ». De quelles façons le fait même d’aller voir une pièce dans ce théâtre participait-il à l’anticipation et au sentiment de peur nécessaire à l’efficacité des pièces ?  Après un bref rappel de l’histoire du Grand-Guignol, les causes externes comme le quartier de Montmartre, mais aussi les habiles coups publicitaires des premiers directeurs artistiques ainsi que la configuration du théâtre lui-même sont étudiées pour montrer comment elles ont largement contribué à créer un véritable mythe autour du Grand-Guignol. Dans la deuxième partie, une analyse spécifique des deux pièces mentionnées précédemment est faite. Les questions suivantes ont été posées : sur quels thèmes pouvaient bien jouer les auteurs pour toucher leur public ? En quoi ces thèmes reflétaient-ils les peurs de l’époque, c’est-à-dire de la « Belle Epoque » ? Dans la dernière partie, une analyse textuelle et scénique a été faite au cours de laquelle il a été tenté de comprendre comment les auteurs provoquent et entretiennent la peur et l’angoisse à travers à la fois la construction dramatique des pièces et leurs jeux de scène.

À beira de um ataque de nervos: um dia na vida de executivos em São Paulo

Ainda que existam pesquisas sobre as funções dos executivos desde 1938 e, ainda que estes trabalhos já tenham desmistificado as atividades cotidianas destes profissionais, o mundo organizacional insiste em atribuir uma aura cheia de glamour ao trabalho de altos executivos. O número de pesquisas acadêmicas realizadas sobre este tema nos anos 80 e 90 não foi muito elevado, mas os recentes escândalos financeiros e as mudanças radicais nas empresas, fizeram ressurgir o interesse sobre o trabalho destes profissionais Este trabalho tem por objetivo mostrar como vivem e trabalham altos executivos em São Paulo, a partir de observação participante de um dia de trabalho de 10 altos executivos. Este relatório foi organizado da seguinte forma: na primeira parte apresenta-se uma revisão dos principais estudos sobre as funções dos executivos; na segunda parte, o trabalho de campo: o acompanhamento, a observação e o registro das atividades realizadas por estes executivos durante um dia típico de trabalho bem como as respostas obtidas a partir de entrevista semi-estruturada sobre aspectos do uso do tempo, funções e vida familiar dos participantes desta amostra, entrevista esta que foi conduzida ao final do acompanhamento do dia de trabalho. Na terceira parte, são discutidos os dados obtidos: ainda que a vida destas pessoas esteja absolutamente centrada em atividades de trabalho, não é possível dizer que elas estejam à beira de um ataque de nervos. Como estão no topo da carreira, seu trabalho consiste na cobrança dos resultados dos funcionários que estão sob seu comando e na construção de redes de relacionamentos que facilitam e ajudam a consolidar e a manter sua posição. Também foi possível observar que os executivos de empresas brasileiras dispõem de maior autonomia no estabelecimento de políticas e tomadas de decisão em comparação com executivos de empresas multinacionais. Além disso, apesar das supostas alterações decorrentes da globalização, nossos resultados não mostram diferenças significativas em relação a trabalhos realizados há mais de 50 anos.

Meus mortos, meus vivos : diálogos com a gravura e a memória

Dividida em dois capítulos, a presente dissertação propõe uma reflexão sobre questões pertinentes à gravura, mais especificamente à litografia, a partir da produção de obras realizadas entre os anos 2000 e 2002 e de seu processo criativo. Gravura, nesta pesquisa, refere-se à linguagem e ao conceito de impressão, deslocando-se de sua função reprodutora em direção ao lugar de obra singular, única. Partindo deste eixo, os conceitos de impressão, memória, aura e sagrado, e as diversas ações que se relacionam à prática da gravura, dialogam com o conceito de identidade vinculado ao retrato e auto-retrato. Neste diálogo, são apresentados aspectos referentes à cultura judaica, seus costumes e rituais. A utilização da fotografia como apropriação, produzindo relações de aproximação e afastamento com a litografia, construíram obras que suscitaram indagações e reflexões a partir de sua instauração, enriquecendo o processo de construção deste texto, que tem como fio condutor o constante interrogar.

A língua estrangeira e sua inclusão no currículo da educação do povo: necessária ou supérflua ?

Este trabalho propõe-se a pesquisa~ os critérios que impelem os legi~ ladores a determinar a adoção ou a supressão da língua estrangeira nos currículos escolare~; identificar as ideologias que servem de suporte a estes critérios; analisar os objetivos da educação formal e determinar o grau de importância do aprendizado da língua estrangeira na consecuçao destes objetivos. Considerando-se os valores que definiram ,os tipos de educação privil~ giados pela sociedade brasileira nas diferentes fases da sua evolução, le vantou-se a seguinte hipótese: o ensino da língua estrangeira tem sido vinculado ao modelo político-econõmico em vigor. Sua adoção ou supressão articula-se com as ideologias que legitimam e sustentam a hegemonia das classes dominantes. Para comprovar esta hipótese, fez-se um levantamento histórico da edu cação no Brasil Çolonial, Imperial e Republicano e sua divisão em perío - dos. Procedeu~se' a uma caracterização político~econômica e sócio-cultural de cada período, identificando-se as ideologias dominantes e suas articulações com a educação. Definiram-se os saberes dominantes superiores e i!!, feri ores , os critérios estabelecidos pelas classes hegemônicas para a transmissão dos mesmos e suas vinculações com o aprendizado da língua estrangeira. Tratou-se da omissão de educação, a partir da impostura do discurso dos detentores do poder decisório, proclamando valores que nao correspondiam ao seu pensamento e sua ação reais; e do caminho percorrido do "humanismo" à "tecnologia", no ensino das línguas estrangeiras, do seu papel de divulgadoras de idéias à transmissão de ideologias. Procurou-se estabelecer de que modo a herança histórica plasmou nosso presente, no d~ IDÍnio da educação, desde o colonialismo até à construção da identidade n~ cional. Identificaram-se razões que recomendam a diversidade de oferta e aprendizado de varias línguas estrangeiras, como componentes, entre outras disciplinas consideradas "supérfluas", da formação do patrimônio intelectual e cultural de cada indivíduo e da corrn.midade como um todo. Conclui-se denunciando os mecanismos adotados pelas classes hegeIDÔnicas para impedir o crescimento educacional do povo, a fim de que este não se torne uma ameaça a esta hegemonia. Como propostas de solução,serão publicadas duas pesquisas j á realizadas: problema quantidade de efetivos 2Lqualidade de ensino da língua estrangeira e o domínio da língua materna x a organização do pensamento x as possibilidades de produção na língua estrangeira.

O lugar do tempo : experiência e tradição em Walter Benjamin

A presente dissertação versa sobre o conceito de experiência em Walter Benjamin. Discute, por conseguinte, a relação que esse conceito mantém com a tradição, a memória, a arte, o tempo, a história e a linguagem no corpus filosófico do autor em questão. Essa constelação de conceitos mantém estreita relação com a religião e a antropologia. Nesse sentido, o texto procura investigar, para além do conhecimento filosófico do autor, as referências antropológicas que constituiriam o substrato místico e político do pensamento benjaminiano sobre a experiência. Walter Benjamin é um pensador da modernidade, escreve a partir dela e para ela. A literatura, como forma de expressão histórica, é basicamente a modalidade artística por intermédio da qual o “filósofo da aura” lê o tempo, a história. A experiência estética, por seu turno, representa o termo em que se sintetiza no autor a modificação da experiência enquanto tal na era moderna. Como crítico cuidadoso da cultura, Benjamin é também seu maior protetor.

O processo de criação do programa Universidade para Todos - PROUNI

From the end of the 80s, the Brazilian higher education experience strong growth, coming from the private sector, which would intensify further in the late 90th Higher education has become a lucrative business. With a drop in the number of students entering and strong competition, the number of idle places in private institutions of higher education reached 49.5% in 2004. That same year, by Measure, was the University for All Program (PROUNI) program, to include high school students from public higher education, offering scholarships to those students in private HEIs. In exchange, the IES gain tax exemption. The objective of this research is to investigate the game of interest occurred in the formulation of this program and identify the model and the political game and has led to the creation of PROUNI, analyzing the process occurred since the wording of a bill, the issue of Measure Law and that the legitimacy PROUNI, with the most important changes made initial model. Since the first draft of the Law to the final Act, the PROUNI was disfigured in its main points, as the percentage of stock for paying students, the process of selection of stock and bond of the IES program. Throughout the process of creating the program, it is quite clear the performance of the institutions representing the private higher education. As reference for the analysis was based on Rational Choice Theory of Political Science. The basic argument of the methods based on rational choice is the maximization of the benefit will be the main motivation of individuals, but they can give that your goals can be achieved more effectively through institutional action and thereby discover that their conduct is shaped by institutions. Thus, individuals rationally choose to get to a certain extent constrained to join in certain institutions, whether voluntarily or not. The PROUNI was submitted by government and public policy covered by the mystical aura of the discourse of social justice and economic development, as in higher education includes a stratum of people who would not have access to the university, due to restrictions in the supply network public higher education. However, the greatest benefit from the program are the private HEIs, which through a difficult time in a scenario marked by high competition and idleness of nearly half of the vacancies offered. The PROUNI became a program that prioritizes access and not the residence of the student to higher education. More serious than a supporting program for students Fellows is a program supporting the institutions of private education

Rodando a bolsinha: dinheiro e relações de prostituição

In this work a series of discussions is made on the relationship between money and prostitution in a way of overcoming its merely economic aspects, in the perception of both being social, cultural and historical phenomena, and taking them as symbols, whose study aids to unveil the reality. In this context it is looked for revealing its forms and contents to make it possible to understand them beyond the rationality, calculability and mathematical elements presents in them; beyond apparentness, taking them in their complexity. The discussions encompass theoretical elements, based especially on Georg Simmel s theoretical analyses, allied to a specific empirical frame that regards the life experience of the women of Praia do Meio, pedaço of the city of Natal-RN-Brazil, where the data were collected from. Fundamentally, prostitution is perceived as an exchange activity, which is not depleted in the economic elements, but, contrarily, starts on them and surpasses them in diverse aspects. It deals about a money-mediated relationship between human beings that possesses in itself a full complexity, which demands an accurate and keen attention to be comprehended. Since money has transformed the world and the men and women in it, the discussions in the text are conducted in a direction to attempt to encircle and understand the relationship between money and prostitution. Prostitution, in turn, aids to understand such a transformation as it is also a symbol of our times and it makes us to face the true essence of our society: the transformation of human beings into merchandise, into negotiable objects. In the money-based society it is possible to picture the phenomenon of double prostitution: negotiation of the human being, through labor, and negotiation of sex, the last being dramatically stigmatized and the former strongly encouraged. This may be demonstrating that the paid sex is, in the money-ruled society, a limit of commercialization, widely accepted provided it is camouflaged and surrounded by an aura of sensuality and legitimacy

Natal como destino turístico : um estudo das imagens (re)veladas pela mídia, pelos turistas e suas implicações educacionais e culturais

This thesis is a result of a research on Natal/RN as a tourist destination. We understand that cities are chosen as tourist destinations beyond its cartographic localization, from other dimensions of meanings that, in its set, constitute images. These images are, probably, very different of the images constructed by native and resident populations, who possess relations of identity with the place. The knowledge of the meanings that others attribute to this city as tourist destination, bring us near to the symbolic bonds established by individuals or social groups on the act of their choices, as well as bring us near to the interaction process city-tourists where the expectations are confirmed or not. The images divulgated by the media also participate of the complex formation of the tourist image that is being constructed and available for the different public, in different social contexts. The tourism constitutes a symbolic asset of the modern society, being considered by the studious, as one of the most expressive phenomena of the modernity, for involving each year displacement and the interaction of thousand of people of different cultures in the entire world. All this people s mobilization points to practical social related to personal motivations, to the entailed desired to the idea to travel and to exceed borders. It is already consensus that tourism is a phenomenon of economic growth, generating jobs, income, professional, qualification, bringing improvements for the host cities. Since 1995, in Brazil, the tourism as a sector of the economy, passed to be considered one of the national priorities, and in this perspective, the national politics of the tourism invested in infrastructure of Brazilian cities with high tourist potential, objecting to increase the flows of Brazilian and foreign tourists. Owing to this fact, the country still invests in programs of tourist marketing, mainly divulging the images of the natural beauties of Brazil abroad. And for Brazilians, the campaigns appeal to rescue the feeling to be Brazilian, associating the idea to travel and know its country. Natal city possesses an excellent positioning in the tourist marketing, being predominantly divulgated in national and international level, for its naturalistic singularity, where the images of its natural enchantments as warm water beaches, white dunes, warm weather, constant breeze and an always blue sky are shown as the favorite scene on this city. From what was viewed above that the choice of a tourist destination articulates from a determined imaginary of a place, already constructed or in process of construction, we consider the knowledge of this imaginary a basic learning for the population of the city and especially, for educators, in the formation of professionals in this area and for tourism managers, elaborators of public politics. Based on this estimative, we developed this research that had as a general objective to identify the images that illustrate Natal city as a tourist destination - our objective of study, particularly the meanings and senses attributed by the tourist marketing (hotel s folders) and by the tourists that visited the city during this study. The discussions and reflections that had guided this research had been given from the theoretical link between imaginary and social representation, also considering some interfaces between the fields of communication and symbol. From the studied authors, Baczko (1985) clarifies that the study of social imaginary is directed for the mechanisms and structures of the social life, especially for the intervention accomplishes and efficient of the representations and symbols in the practical collectives, as well as in its direction and orientation . Following this same thought, Moscovici (1978) says that the social representation are produced in communicational and symbolic contexts, and these representations once that already constituted circulate socially as almost tangible entities. Based on this fundament and on the analyze of Barthes (1990), particularly in the approach given to the reading of photographic image, we could observe on hotel s folders that each page evidences senses and meanings of functionality of internal and external spaces, pointing to the way of leisure offered by the keepers of city which is the hotels. About, the leisure that they offer, it is directed to young public, giving meaning to the young myth of personalized leisure tourism on children, young and adults images. The image about security that hotels offer and the singular image of Natal city as a paradise place, provide an idealization of pleasure through the sun, dunes, and beaches and also due to the hospitability of the natives who are assigned as educated . For the tourist that participated on this research, Natal city is tied only by the imaginary of leisure and nature which constitute the emotional link of the relation media-city-tourist. And with such force and fullness of directions the city discloses without tensions and contradictions as a place protected by a mythical and sacred aura. The study also demonstrates us that the potiguar culture remains (almost) forgotten, due to the silenced in this imaginary. In this perspective, we highlight that this culture silence is very close related to the disvalue of education in its general meaning. We defend that the imaginary apprehended constitutes a new reading and a new looking and understanding the tourist reality that comes historically consolidating in this city. In this direction, we glimpse that this study and its future dismemberments can collaborate with the process of rescue the cultural values of the potiguar people, in the way that the meaning of tourist may be redefined, and the tourist image of the city can be also disclosed for its identities particularities of its culture

A educação do leitor em Machado de Assis: da crítica literária às Memórias Póstumas de Brás Cubas

Critical analysis of the international classification of headache disorders diagnostic criteria (ICHD I-1988) and (ICHD II-2004), for migraine in children and adolescents

The present study analyzed the (ICHD I-1988) and ( ICHD II-2004) diagnostic criteria in children and adolescents. Our population consisted of 496 patients of the Headache Outpatient Ward for Children and Adolescents retrospectively studied from 1992 to 2002. Individuals were classified according to three diagnostic groups: Intuitive Clinical Diagnosis ( Gold Standard), ICHD I-1988 and ICHD II-2004. They were statistically compared using the variables: Sensitivity ( S), Specificity (Sp), Positive Predictive Value (PPV), Negative Predictive Value (NPV). When ICHD I-1988 was used, the sensitivity of migraine without and with aura was 21% and 27%, respectively, whereas in ICHD II-2004 it changed to 53% and 71% without affecting specificity. As a conclusion, the current classification criteria ( ICHD II-2004) showed greater sensitivity and high specificity for migraine than ICHD I-1988, although it improved migraine diagnosis in children and adolescents, the sensitivity remains poor.
