This paper investigates relationships between cooperation, R&D, innovation and productivity in Spanish firms. It uses a large sample of firm-level micro-data and applies an extended structural model that aims to explain the effects of cooperation on R&D investment, of R&D investment on output innovation, and of innovation on firms’ productivity levels. It also analyses the determinants of R&D cooperation. Firms’ technology level is taken into account in order to analyse the differences between high-tech and low-tech firms, both in the industrial and service sectors. The database used was the Technological Innovation Panel (PITEC) for the period 2004-2010. Empirical results show that firms which cooperate in innovative activities are more likely to invest in R&D in subsequent years. As expected, R&D investment has a positive impact on the probability of generating an innovation, in terms of both product and process, for manufacturing firms. Finally, innovation output has a positive impact on firms’ productivity, being greater in process innovations. Keywords: innovation sources; productivity; R&D Cooperation

Objectives: Nasopalatine duct cysts (NPDCs) are the most common developmental, epithelial and non-odontogenic cysts of the maxillae. The present study describes the clinicopathological characteristics of 22 NPDCs and discusses their etiology, incidence, treatment and prognosis, with a review of the literature on the subject. Study design: A retrospective observational study was made comprising a period of 36 years (1970-2006), and yielding a series of 22 patients with histopathological confirmation of NPDC. Surgical treatment was carried out under local anesthesia and comprised the dissection and removal of the cyst adopting a usually palatine approach, with the preparation of an enveloping flap from 1.4 to 2.4. Results: No statistically significant correlation was observed between the size of the lesion and patient age, although the size of the cyst differed according to patient gender, with a mean NPDC diameter of 16 mm in males and 12 mm in females. In no case did we observe root reabsorption or loss of vitality of the upper incisors following surgery. The X-ray image was rounded in 15 cases and heart-shaped in the remaining 7 cases. In the majority of cases panoramic X-rays and periapical and occlusal X-rays sufficed to identify the lesion, though computed tomography was used in cases of doubt. Conclusions: The etiology of NPDC is unclear. Simple surgical resection is recommended, followed by clinical and radiological control to ensure correct resolution of the case.

Antecedentes: La parada cardiorrespiratoria es uno de los principalesproblemas sanitarios en los países desarrollados, además de por la mortalidadproducida, por las importantes repercusiones neurológicas posteriores quepresentan las personas que sobreviven. Hasta un 64% de los supervivientespuede presentar secuelas de gravedad, y tan solo un 1,4% queda exento dealgún tipo de alteración neurológica. Distintos ensayos clínicos, muestran quela hipotermia inducida ligera, es decir, el descenso controlado de latemperatura corporal mejora la supervivencia y los daños neurológicos en lospacientes adultos inconscientes tras una resucitación cardiopulmonar. Sinembargo, no está del todo claro cuáles son los pacientes más indicados pararecibir la terapia, la técnica de inducción ideal, la temperatura objetivo, suduración y la tasa idónea de recalentamiento.Objetivos: El objetivo del estudio es conocer la técnica de hipotermiaterapéutica como cuidado posresucitación tras sufrir una parada cardíaca.Metodología: Para ello, se realizó una búsqueda bibliográfica a través de lassiguientes bases de datos: CSIC, Medline PubMed, CINAHL, BibliotecaCochrane, Cuiden Plus, Dialnet, Scopus y ScienceDirect. Finalmente, seaceptaron 8 artículos que pertenecían a los criterios de inclusión: revisionessistemáticas, ensayos clínicos, revisiones bibliográficas y documentos deconsenso tras consejo de expertos, en español o inglés, publicados desde elaño 2005 hasta el año 2013 cuyos sujetos de estudio son adultos.Resultados: en la actualidad, se recomienda que los pacientes adultosinconscientes, con recuperación de la circulación espontánea tras una paradacardíaca extrahospitalaria, deben ser enfriados a 32-34ºC durante un periodode 12-24 horas cuando el ritmo inicial sea fibrilación ventricular. Se establecen4 periodos de tratamiento: inducción (desde el ingreso en la unidad hasta quese alcanzan los 33ºC), mantenimiento (desde el logro de los 33ºC hasta 24horas después), recalentamiento (12 horas de incremento de la temperatura,hasta alcanzar los 37ºC) y estabilización térmica (12 horas posteriores aalcanzar los 37ºC). Los métodos de inducción y mantenimiento de la hipotermiason diversos y se establecen dos grupos: técnicas invasivas y no invasivas.Palabras clave: hipotermia inducida, parada cardíaca, técnicas enfriamiento

Drug safety issues pose serious health threats to the population and constitute a major cause of mortality worldwide. Due to the prominent implications to both public health and the pharmaceutical industry, it is of great importance to unravel the molecular mechanisms by which an adverse drug reaction can be potentially elicited. These mechanisms can be investigated by placing the pharmaco-epidemiologically detected adverse drug reaction in an information-rich context and by exploiting all currently available biomedical knowledge to substantiate it. We present a computational framework for the biological annotation of potential adverse drug reactions. First, the proposed framework investigates previous evidences on the drug-event association in the context of biomedical literature (signal filtering). Then, it seeks to provide a biological explanation (signal substantiation) by exploring mechanistic connections that might explain why a drug produces a specific adverse reaction. The mechanistic connections include the activity of the drug, related compounds and drug metabolites on protein targets, the association of protein targets to clinical events, and the annotation of proteins (both protein targets and proteins associated with clinical events) to biological pathways. Hence, the workflows for signal filtering and substantiation integrate modules for literature and database mining, in silico drug-target profiling, and analyses based on gene-disease networks and biological pathways. Application examples of these workflows carried out on selected cases of drug safety signals are discussed. The methodology and workflows presented offer a novel approach to explore the molecular mechanisms underlying adverse drug reactions

El presente trabajo traslada el debate académico alrededor del mayor riesgo de pobreza que afrontan las mujeres en relación a los hombres al contexto español. Tras una breve revisión bibliográfica de los datos disponibles sobre la pobreza femenina en países industrializados y sus posibles causantes, se ponen a prueba esos mismos factores potencialmente culpables en el caso español. Del EU-SILC de 2010 se ha sacado una muestra formada únicamente por mujeres y hombres que o bien viven solos o con hijos a su cargo y, partiendo de ella, el método de la regresión logística ha concluido que hay factores exclusivamente explicativos de la pobreza femenina. Ser madre soltera, ser joven (entre 16 y 25 años) y no haber nacido en España tienen una importante capacidad explicativa de la pobreza femenina mientras no son significativas como explicación de la pobreza masculina. Si a estos factores añadimos no tener un trabajo, un bajo logro educativo y no recibir ningún subsidio individual, obtenemos un conjunto de factores que explican un 26.8% de los casos de mujeres españolas pobres que viven solas o son madres solteras. Estos datos ponen de relieve la necesidad de más investigaciones al respecto que consigan un mayor poder explicativo.

This paper analyzes the profile of Spanish young innovative companies (YICs) and the determinants of innovation and imitation strategies. The results for an extensive sample of 2,221 Spanish firms studied during the period 2004–2010 show that YICs are found in all sectors, although they are more concentrated in high-tech sectors and, in particular, in knowledge-intensive services (KIS). Three of every four YICs are involved in KIS. Our results highlight that financial and knowledge barriers have much impact on the capacity of young, small firms to innovate and to become YICs, whereas market barriers are not obstacles to becoming a YIC. Public funding, in particular from the European Union, makes it easier for a new firm to become a YIC. In addition, YICs are more likely to innovate than mature firms, although they are more susceptible to sectoral and territorial factors. YICs make more dynamic use of innovation and imitation strategies when they operate in high-tech industries and are based in science parks located close to universities. Keywords: innovation strategies, public innovation policies, barriers to innovation, multinomial probit model. JEL Codes: D01, D22 , L60, L80, O31

Prepositional phrases are the commonest kind of postmodification in all registers of English (Biber et al. 1999: 634). The locative ones that can be expanded into a defining relative clause (the books [which are] on the table) are usually expressed by such a construction in Spanish (los libros que están encima de la mesa) or by a phrase introduced by de (los libros de encima de la mesa). Wonder (1979) argues that Spanish allows locative phrases with prepositions other than de in the case of"situaciones"activas"" (el aterrizaje en pleno campo) as against"situaciones estáticas" (*el sofá en la sala), and if the phrase can be given an adverbial rather than, or in addition to, an adjectival interpretation (el ruido en la calle), especially if that phrase implies an alternative location for an object or contrast with another similar object (el sofá en la sala contigua). This paper further investigates this claim and looks at Spanish equivalents of English postmodifying prepositional phrases in general, while proposing an explanation for the choice of these different structures in Spanish based on considerations of lexical density. Resumen: Las frases preposicionales constituyen el tipo más frecuente de posmodificación en todos los registros del inglés (Biber et a. 1999: 634). En el español, las expresiones locativas suelen incorporar un pronombre relativo y un verbo (the books [which are] on the table > los libros que están encima de la mesa), o bien expresarse mediante una frase introducida por la preposición de (los libros de encima de la mesa). Wonder (1979) sostiene que el español permite el uso de preposiciones que no sean de en las frases locativas en el caso de"situaciones"activas"" (el aterrizaje en pleno campo) frente a"situaciones estáticas" (*el sofá en la sala), y también si la frase puede tener una función adverbial antes que, o además de, una interpretación adjetiva (el ruido en la calle), sobre todo si dicha frase encierra la idea de una posición alternativa para un objeto, o bien un contraste con otro objeto similar (el sofá en la sala contigua). El presente estudio pretende examinar este argumento y, además, explorar la posmodificación preposicional en español de un modo más general, a la par que propone una explicación sobre la elección de estructura en español que se basa en el criterio de la densidad léxica.

This article introduces EsPal: a Web-accessible repository containing a comprehensive set of properties of Spanish words. EsPal is based on an extensible set of data sources, beginning with a 300 million token written database and a 460 million token subtitle database. Properties available include word frequency, orthographic structure and neighborhoods, phonological structure and neighborhoods, and subjective ratings such as imageability. Subword structure properties are also available in terms of bigrams and trigrams, bi-phones, and bi-syllables. Lemma and part-of-speech information and their corresponding frequencies are also indexed. The website enables users to either upload a set of words to receive their properties, or to receive a set of words matching constraints on the properties. The properties themselves are easily extensible and will be added over time as they become available. It is freely available from the following website: http://www.bcbl.eu/databases/espal

Over the last few decades, advances have been made in the understanding of myofascial pain syndrome epidemiology, clinical characteristics and aetiopathogenesis, but many unknowns remain. An integrated hypothesis has provided a greater understanding of the physiopathology of trigger points, which may allow the development of new diagnostic, and above all, therapeutic methods, as well as the establishment of prevention policies and protocols by the health profession. Nevertheless, randomized studies are needed to provide a better understanding and detection of the different factors involved in the origin of trigger points.

In response to an increasing need for ever-shorter personality instruments, Gosling, Rentfrow, and Swann (2003) developed the Ten-Item-Personality Inventory (TIPI), which measures the dimensions of the Five Factor Model (FFM) using 10 items (two for each dimension) and can be administered in about one minute. In two studies and using a multi-judge (self and observer) and multi-instrument design, we develop Spanish (Castilian) and Catalan versions of the TIPI and evaluate them in terms of internal consistency, test-retest reliability, convergent, discriminant, and content validity, as well as self-observer correlations. Test-retest correlations were strong, and convergence with the NEO-PI-R factors was significant. There were also strong correlations between observer ratings and the participants’ self-ratings. Despite some inconsistencies with respect to the Agreeableness scale, the Catalan translation and both translations into Spanish of the original TIPI demonstrated sufficient psychometric properties to warrant use as a Five Factor personality measure when the use of longer instruments is not convenient or possible. Furthermore, as the first translation of a brief standard Big Five Instrument into Catalan, this work should facilitate future research on personality in the Catalan-speaking population.

We describe a female patient with a midline syndrome. The patient presents agenesis of the corpus callosum, encephalocele, iris coloboma, hypertelorism, submucosal cleft palate and dental anomalies. Despite being very characteristic, her phenotypical traits do not coincide exactly with those reported to date in the literature. The karyotype and the molecular cytogenetic study do not show mutations. We identify the presence of dental anomalies in the mother and other family members, not being identified MSX1 and PAX9 mutations that could the related with their etiology. Despite the fact that dental agenesis has been related to a large number of other malformation syndromes and congenital conditions, dental anomalies have only rarely been mentioned when reporting midline syndromes. These dental phenotypical traits, present in the patient and her family, could be considered part of the midline syndrome in carriers as well as in the patients.

Aim: To identify prophylactic antibiotic prescription practices among Spanish dentists with preferential dedication to Oral Surgery in different types of tooth extraction surgeries. Method: Members of the Spanish Oral Surgery Society were surveyed on antibiotic prophylaxis use in 4 different tooth extraction modalities scaled according to their surgical invasiveness. Results: Sixty-nine of the 105 distributed questionnaires were returned completed. Thirteen percent of the surveyed surgeons would prescribe antibiotics to prevent postoperative wound infection when confronted with conventional tooth extraction lasting less than 5 minutes. In the case of surgery lasting more than 5 minutes, the percentage of participants that would prescribe antibiotics increased to 39%. When a mucoperiosteal flap was elevated or an ostectomy was performed, 87% and 100%, respectively, would prescribe antibiotic prophylaxis. Amoxicillin and its combination with clavulanic acid were the most commonly prescribed antibiotics. All participants would prescribe the antibiotic orally, starting after surgery and with a duration that ranged from 2-8 days. Conclusions: The results obtained suggest that antibiotic prophylaxis for preventing local odontogenic infection is not being correctly implemented in Spain. This can generate new bacterial resistances, facilitate adverse drug reactions and favor opportunistic infections. Better designed studies are needed in order to clarify the role of antibiotics in the prevention of postsurgical wound infection

Objectives: To evaluate the prevalence of dental agenesis and its possible association with other developmental dental anomalies and systemic entities. Setting and Sample Population: Descriptive transversal study, for which 1518 clinical records, of patients visited by the Odontological Service of the Primary Health Centre of Cassà de la Selva (Girona-Spain) between December 2002 and February 2006 were reviewed. The data were recorded in relation to the oral and dental anomalies and the associated systemic entities, between the ones referred as concomitant in literature. Results: Values of 9.48% (7.25% excluding the third molars) for dental agenesis and 0.39% for oligodontia were obtained. The presence of dental agenesis concomitant with some other forms of oral and dental anomalies was observed. Attention must be drawn to the fact that a greater number of concomitant systemic entities were observed in those patients that presented a severe phenotypical pattern of dental agenesis. Conclusions: The results of the present study do not differ from the ones reported in studies of similar characteristics among Occidental and Spanish populations. The relationship observed between certain systemic entities and developmental dental anomalies suggest a possible common genetic etiology
