Estimating United States Phillips Curves With Expectations Consistent With The Statistical Process Of Inflation

‘Modern’ Phillips curve theories predict inflation is an integrated, or near integrated, process. However, inflation appears bounded above and below in developed economies and so cannot be ‘truly’ integrated and more likely stationary around a shifting mean. If agents believe inflation is integrated as in the ‘modern’ theories then they are making systematic errors concerning the statistical process of inflation. An alternative theory of the Phillips curve is developed that is consistent with the ‘true’ statistical process of inflation. It is demonstrated that United States inflation data is consistent with the alternative theory but not with the existing ‘modern’ theories.

Evaluation of prenatal ultrasound diagnosis of fetal abdominal wall defects by 19 European registries.

OBJECTIVES: To evaluate the current effectiveness of routine prenatal ultrasound screening in detecting gastroschisis and omphalocele in Europe. DESIGN: Data were collected by 19 congenital malformation registries from 11 European countries. The registries used the same epidemiological methodology and registration system. The study period was 30 months (July 1st 1996-December 31st 1998) and the total number of monitored pregnancies was 690,123. RESULTS: The sensitivity of antenatal ultrasound examination in detecting omphalocele was 75% (103/137). The mean gestational age at the first detection of an anomaly was 18 +/- 6.0 gestational weeks. The overall prenatal detection rate for gastroschisis was 83% (88/106) and the mean gestational age at diagnosis was 20 +/- 7.0 gestational weeks. Detection rates varied between registries from 25 to 100% for omphalocele and from 18 to 100% for gastroschisis. Of the 137 cases of omphalocele less than half of the cases were live births (n = 56; 41%). A high number of cases resulted in fetal deaths (n = 30; 22%) and termination of pregnancy (n = 51; 37%). Of the 106 cases of gastroschisis there were 62 (59%) live births, 13 (12%) ended with intrauterine fetal death and 31 (29%) had the pregnancies terminated. CONCLUSIONS: There is significant regional variation in detection rates in Europe reflecting different policies, equipment and the operators' experience. A high proportion of abdominal wall defects is associated with concurrent malformations, syndromes or chromosomal abnormalities, stressing the need for the introduction of repeated detailed ultrasound examination as a standard procedure. There is still a relatively high rate of elective termination of pregnancies for both defects, even in isolated cases which generally have a good prognosis after surgical repair.

Surfactant protein-D and exposure to bioaerosols in wastewater and garbage workers.

PURPOSE: Bioaerosols and their constituents, such as endotoxins, are capable of causing an inflammatory reaction at the level of the lung-blood barrier, which becomes more permeable. Thus, it was hypothesized that occupational exposure to bioaerosols can increase leakage of surfactant protein-D (SP-D), a lung-specific protein, into the bloodstream. METHODS: SP-D was determined by ELISA in 316 wastewater workers, 67 garbage collectors, and 395 control subjects. Exposure was assessed with four interview-based indicators and by preliminary endotoxin measurements using the Limulus amoebocyte lysate assay. Influence of exposure on serum SP-D was assessed by multiple linear regression considering smoking, glomerular function, lung diseases, obesity, and other confounders. RESULTS: Overall, mean exposure levels to endotoxins were below 100 EU/m(3). However, special tasks of wastewater workers caused higher endotoxin exposure. SP-D concentration was slightly increased in this occupational group and associated with the occurrence of splashes and contact to raw sewage. No effect was found in garbage collectors. Smoking increased serum SP-D. No clinically relevant correlation between spirometry results and SP-D concentrations appeared. CONCLUSIONS: These results support the hypothesis that inhalation of bioaerosols, even at low concentrations, has a subclinical effect on the lung-blood barrier, the permeability of which increases without associated spirometric changes.

El paper de l'esport en la integració de la població adulta immigrant d'origen internacional a Catalunya

Amb l’establiment de grups d’immigrants a Catalunya, l’abast de les polítiques socials s’ha vist ampliat per tal d’afrontar els reptes d'integració i cohesió social. Tot i que la Generalitat de Catalunya i la Diputació de Barcelona identifiquen t l’esport com a vehicle positiu per a la integració dels immigrants, el desenvolupament de polítiques en aquest àmbit encara està en una fase preliminar. La manca de recerca i l’absència d’aproximació política dificulten aquest procés. Comprendre la realitat de la participació esportiva entre la població adulta immigrant pot servir per millorar els processos de formulació i implementació de polítiques per part de les administracions públiques catalanes. S’ha realitzat una aproximació exploratòria a aquesta necessitat. La recollida de dades s’ha fet mitjançant observació i entrevistes semi-estructurades sobre experiències esportives organitzades o semi-organitzades rellevants. Els resultats revelen la importància de l’esport per a l’immigrant en el procés d’establiment de xarxes socials, i per al manteniment, la reproducció i la negociació de les identitats culturals i, en particular, nacionals. Hi ha una divisió entre el sistema esportiu formal català i els sistemes informals i fragmentats que utilitzen els immigrants per organitzar activitats esportives. Les entrevistes realitzades a actors clau en els diferents nivells de l’administració pública i el cas d’estudi d’un municipi han proporcionat una visió general de la resposta política. Es proposen un conjunt de recomanacions referents a la necessitat de gestionar les xarxes socials de forma més sistemàtica, la necessitat d’incrementar les accions de transversalitat horitzontal i vertical entre els actors públics i d’establir un conjunt d’indicadors socials per mesurar l’efectivitat de la intervenció política en aquest àmbit, així com la identificació de bones pràctiques i activitats per compartir coneixements.

Current Molecular Imaging of Spinal Tumors in Clinical Practice.

Energy metabolism measurements in spinal cord tumors, as well as in osseous spinal tumors/metastasis in vivo, are rarely performed only with molecular imaging (MI) by positron emission tomography (PET). This imaging modality developed from a small number of basic clinical science investigations followed by subsequent work that influenced and enhanced the research of others. Apart from precise anatomical localization by coregistration of morphological imaging and quantification, the most intriguing advantage of this imaging is the opportunity to investigate the time course (dynamics) of disease-specific molecular events in the intact organism. Most importantly, MI represents one of the key technologies in translational molecular neuroscience research, helping to develop experimental protocols that may later be applied to human patients. PET may help monitor a patient at the vertebral level after surgery and during adjuvant treatment for recurrent or progressive disease. Common clinical indications for MI of primary or secondary CNS spinal tumors are: (i) tumor diagnosis, (ii) identification of the metabolically active tumor compartments (differentiation of viable tumor tissue from necrosis) and (iii) prediction of treatment response by measurement of tumor perfusion or ischemia. While spinal PET has been used under specific circumstances, a question remains as to whether the magnitude of biochemical alterations observed by MI in CNS tumors in general (specifically spinal tumors) can reveal any prognostic value with respect to survival. MI may be able to better identify early disease and to differentiate benign from malignant lesions than more traditional methods. Moreover, an adequate identification of treatment effectiveness may influence patient management. MI probes could be developed to image the function of targets without disturbing them or as treatment to modify the target's function. MI therefore closes the gap between in vitro and in vivo integrative biology of disease. At the spinal level, MI may help to detect progression or recurrence of metastatic disease after surgical treatment. In cases of nonsurgical treatments such as chemo-, hormone- or radiotherapy, it may better assess biological efficiency than conventional imaging modalities coupled with blood tumor markers. In fact, PET provides a unique possibility to correlate topography and specific metabolic activity, but it requires additional clinical and experimental experience and research to find new indications for primary or secondary spinal tumors.

Gastroschisis - what should be told to parents?

Gastroschisis is a common congenital abdominal wall defect. It is almost always diagnosed prenatally thanks to routine maternal serum screening and ultrasound screening programs. In the majority of cases, the condition is isolated (i.e. not associated with chromosomal or other anatomical anomalies). Prenatal diagnosis allows for planning the timing, mode and location of delivery. Controversies persist concerning the optimal antenatal monitoring strategy. Compelling evidence supports elective delivery at 37 weeks' gestation in a tertiary pediatric center. Cesarean section should be reserved for routine obstetrical indications. Prognosis of infants with gastroschisis is primarily determined by the degree of bowel injury, which is difficult to assess antenatally. Prenatal counseling usually addresses gastroschisis issues. However, parental concerns are mainly focused on long-term postnatal outcomes including gastrointestinal function and neurodevelopment. Although infants born with gastroschisis often endure a difficult neonatal course, they experience few long-term complications. This manuscript, which is structured around common parental questions and concerns, reviews the evidence pertaining to the antenatal, neonatal and long-term implications of a fetal gastroschisis diagnosis and is aimed at helping healthcare professionals counsel expecting parents. © 2013 John Wiley & Sons, Ltd.

Análisis de la relación entre la formación y el empleo en el caso de las trabajadoras en el cuidado en domicilio de personas en situación de dependencia

El proyecto de investigación desarrollado durante el período de la beca se inserta en el marco del proyecto de investigación titulado "Especialidad de formación, especialidad de empleo y resultados de inserción laboral" (ESFOREM). La primera línea de investigación desarrollada se centró en el análisis macroestadístico de la relación entre la formación y el empleo en el caso de los jóvenes españoles a partir del análisis estadísitico de los datos proporcionados por la Encuesta ETEFIL (INE, 2005). El propósito de la investigación era cotejar en qué medida los jóvenes con nivel educativo no universitario estaban trabajando de aquello para lo cual se habían formado específicamente según el Catálogo Nacional de Cualificaciones (adecuación normativa) y hasta qué punto la no correspondencia entre el empleo (según su nivel y especialidad) y la formación (según su nivel y especialidad) suponía una fracaso respecto a su inserción laboral. Enfoques dominantes sobre la relación entre formación y empleo parten del supuesto normativo de que la correspondencia entre especialidad de formación y especialidad de empleo es la situación óptima y se postula que la dinámica del mercado de trabajo tiende a propiciarla. El proyecto ESFOREM tenía una segunda línea de investigación que planteaba un análisis cualitativo de dos subsectores específicos. Esta tesis doctoral se inserta en la segunda línea de investigación desarrollada y tiene como propósito analizar y explicar, mediante una estrategia de investigación cualitativa un caso específico de modalidad de relación en la que no existe correspondencia entre formación y empleo, de forma tal de poder analizar y explicar el papel activo que los agentes e instituciones tienen en la configuración de la relación. El caso seleccionado ha sido del "empleo de cuidado en domicilio depersonas en situación de dependencia", con el objetivo de contribuir a profundizar en el estudio de un sector de empleo que es cada vez más emergente y que está fuertemente feminizado. Dicho estudio se realiza a nivel comparado y municipal entre Montevideo y Barcelona.

En aquest TFC es revisa el paper que van tenir les dones periodistes durant la Transició espanyola. Així mateix s'analitza aquest moment històric concret i la seva influència en la premsa en general i en la llibertat d'expressió en particular.

Utilització de la hipertextualitat a la premsa digital a Catalunya i a Espanya

Internet és, probablement, la via de comunicació que menys temps ha necessitat per fer-se imprescindible en les nostres vides, una eina en constant evolució que ens permet aprendre i comunicar-nos a qualsevol hora. A més, Internet ha permès al periodisme créixer més enllà de les fronteres del paper i la tinta. Gràcies al ciberespai, el periodisme tradicional ha anat evolucionant i ha donat lloc al periodisme digital o ciberperiodisme, permetent així el naixement de nous mitjans de comunicació amb unes característiques, un llenguatge i uns gèneres periodístics propis. El present Treball de Fi de Carrera consisteix en l’anàlisi empírica i la posterior interpretació d’un dels principals símptomes de maduresa del periodisme digital: la utilització dels recursos hipertextuals. D’aquesta manera i durant un mes, s’han analitzat quatre diaris digitals pure player, dos catalans (www.vilaweb.cat i www.e-noticies.cat) i dos espanyols (www.elplural.com i www.elconfidencial.com), amb l’objectiu de determinar la utilització i l’evolució de l’ús de la hipertextualitat a la premsa digital a Catalunya i a Espanya. A través de totes les dades obtingudes gràcies a l’anàlisi realitzada es podrà conèixer quin tipus d’enllaç és el més utilitzat, quins mitjans són els que utilitzen més la hipertextualitat o quina és la mitjana d’enllaços per notícia, entre d’altres aspectes. A més, tota la informació resultant permetrà validar o refutar les hipòtesis plantejades durant la elaboració d’aquest treball.

Gender gap index in Spain by regions

Every year, the World Economic Forum publishes the World Gender Gap Report mainly based on the results of the Global Gender Gap Index (GGGI) computed by country. This index is made out of four subindexes to capture the magnitude of the gender gap in 4 areas: educational attainment, economic participation and opportunity, political empowerment, and health and survival; its methodology was reformed in 2006. In this paper we adapt the GGGI to construct a Regional Gender Gap Index (RGGI) and we compute it by regions (Comunidades Autónomas) in Spain with 2006 data. The RGGI could be applied to other regions. Results of the RGGI show that not only are there gender gap differences between Spanish regions in Spain, but that there are at the political empowerment and economic participation and opportunity categories that those differences are strongest. Geographic distribution of the gender gap shows that the deepest gaps are, in general, located in the northern regions (Euskadi, with a high score, and Murcia and Extremadura, with low scores, being exceptions); this is mainly due to the poor participation in politics of women in those regions.

Genome-wide association and genetic functional studies identify autism susceptibility candidate 2 gene (AUTS2) in the regulation of alcohol consumption.

Alcohol consumption is a moderately heritable trait, but the genetic basis in humans is largely unknown, despite its clinical and societal importance. We report a genome-wide association study meta-analysis of ∼2.5 million directly genotyped or imputed SNPs with alcohol consumption (gram per day per kilogram body weight) among 12 population-based samples of European ancestry, comprising 26,316 individuals, with replication genotyping in an additional 21,185 individuals. SNP rs6943555 in autism susceptibility candidate 2 gene (AUTS2) was associated with alcohol consumption at genome-wide significance (P = 4 × 10(-8) to P = 4 × 10(-9)). We found a genotype-specific expression of AUTS2 in 96 human prefrontal cortex samples (P = 0.026) and significant (P < 0.017) differences in expression of AUTS2 in whole-brain extracts of mice selected for differences in voluntary alcohol consumption. Down-regulation of an AUTS2 homolog caused reduced alcohol sensitivity in Drosophila (P < 0.001). Our finding of a regulator of alcohol consumption adds knowledge to our understanding of genetic mechanisms influencing alcohol drinking behavior.

The role of basalt replenishment in the generation of basaltic andesites of the ongoing activity at Arenal volcano, Costa Rica: evidence from clinopyroxene and spinel

The bulk composition of magma erupted from Volcan Arenal has remained nearly constant (SiO2 = 53.6-54.9 wt%; MgO = 5.0-4.5 wt%) during almost 30 years of continuous activity (1969-1996). None the less, clinopyroxene (cpx) phenocrysts and their spinel inclusions record a much more complex open-system evolution in which steady-state production of the erupted basaltic andesitic magma is linked to episodic injections of basalt into Arenal's magma conduit/reservoir system. High-resolution major element zoning profiles (electron microprobe) on a large number of phenocrysts (>14,000 analyses), tied to back-scattered electron (BSE) images, have been used to assess the compositional characteristics of the magmatic end members as well as the timing and dynamics of magma replenishment events. No two cpx phenocrysts have exactly the same zoning profile. The vast majority of our analyses record the crystallization of cpx (Cr2O3 < 0.12 wt%; Mg# = 65-79; Al/Ti = 2-7) from a liquid comparable to or more evolved than erupted magma compositions. However, half of all cpx grains are cored by high-Cr cpx (Cr2O3 = 0.2-0.72 wt%) or contain similar basaltic compositions as abrupt growth bands in phenocrysts with and without high-Cr cores; phenocrysts with high-Cr cpx occur throughout the ongoing activity. In a few cases, high-Cr cpx occurs very near the outer margin of the grain without an apparent growth hiatus, particularly in 1968/69 and 1992/93. The main conclusions are: (1) all basaltic andesitic lavas erupted at Arenal during the ongoing activity that began in July, 1968, are the products of magma mixing, (2) clinopyroxenes record multiple replenishment events of basaltic magma in contrast to the near constancy of erupted bulk compositions, (3) some phenocrysts preserve records of multiple interactions with basaltic magmas requiring magmatic processes to operate on time-scales shorter than residence times of some phenocrysts, (4) multiple occurrences of clinopyroxene with high-Cr rims suggest that basalt replenishment events have occurred with sub-decadal frequency and may predate eruption by months or less. From this we infer that Arenal volcano is underlain by a continuously active, small-volume magmatic reservoir maintained in quasi-steady state by basalt recharge over several decades. The monotony of erupting Arenal magmas implies that fractionation, recharge, ascent, and eruption are well balanced in order for magmas to be essentially uniform while containing phenocrysts with vastly different growth histories at the time of eruption.

Circulating Antigens Levels in Different Clinical Forms of the Schistosoma mansoni Infection

With the aim to evaluate the circulating cathodic antigen (CCA) levels in relation to the different clinical phases of Schistosoma sp. infection a sandwich ELISA using monoclonal antibody 5H11 was performed. The sera of three groups of 25 Brazilian patients with acute, intestinal and hepatosplenic forms of S. mansoni infection were tested and compared to a non-infected control group. Patients and control groups were matched for age and sex and the number of eggs per gram of feces was equally distributed among the three patient groups. Sensitivity of 100%, 72%, 52% of the assay was observed for the intestinal, hepatosplenic and acute toxemic groups respectively. The specificity was 100%. Intestinal and hepatosplenic groups presented CCA levels significantly higher in comparison to those observed for acute patients (F-ratio = 2,524; p = 0.000 and F-ratio = 6,314; p = 0.015 respectively). There was no significant difference of CCA serum levels between hepatosplenic and intestinal groups (F-ratio = 1,026; p = 0.316).
