Hospitals from ancient Seville had an important heritage for survival of the institution and its patients. In order to keep this heritage, the officialdom settled down several control mechanisms that would serve to manage a profitable management of their income and rights. For this purpose, they developed devising instruments able to preserve their possessions and put them into operation. This article attempts to identify the defining elements of these books, called “protocolos de bienes” (protocols goods), indicating their characteristics and evolution from archaic models until the final form. This final form was reached late sixteenth and early seventeenth century, at which time devoted use main codex of hospitality. To do this, we used the documentary collec-tions of Seville, preserved in different archives of the city, from where they have taken several significant examples showing the changes that occurred in both its internal structure and its mate-rials manufacturing, underlining the participation of official, booksellers, illuminators and calligraphers. Similarly, it has high-lighted the multifaceted and multifunctional character of this ins-titutions that became also a corporate identity. The multiplicity of hospitals in Sevilla had different types and features of protocols, which were modificated according to the different needs of each institution.

Recently shown in some termites, Asexual Queen Succession (AQS) is a reproductive strategy in which the primary queen is replaced by numerous parthenogenetically-produced neotenic queens that mate with the primary king. In contrast, the workforce and alate dispersers are produced sexually. If the primary king is replaced by a sexually-produced neotenic son, the matings between neotenic male and females beget asymmetries in the reproductive value of alates, promoting a female-biased alate sex-ratio. Cavitermes tuberosus (Termitidae: Termitinae) is a soil-feeding tropical species, which shows parthenogenetically-produced neotenics and an AQS syndrome. Our work aims to characterize the reproductive strategies in this species by determining (i) the developmental scheme, (ii) the genetic origin of sexuals, (iii) the level of genetic structure (analysis of 65 nests distributed in 14 sites) and (iv) the alate sex-ratio.Our results show that (i) neotenic females develop from the third or fourth nymphal instar; (ii) the majority of neotenic females (82%) are parthenogenetically-produced while only 2% of female alates are so; (iii) nests are differentiated within sites, indicating that the foundation of new nests mainly occurs by nuptial flights; (iv) numerical sex-ratio of alate-destined sexuals is balanced (SRN=0.509, IC95%=0.497-0.522) while investment sex-ratio is slightly female-biased (SRE=0.529, IC95%=0.517-0.542). Altogether, our results demonstrate AQS and its implications in C. tuberosus, and reveal particularities compared to other species in which AQS has been demonstrated: neotenic-headed nests are less frequent than primary-headed ones and neotenic females never become physogastric. AQS is found in various ecological contexts and seems phylogenetically more widespread than previously thought. This strategy shows some evolutionary advantages but these seem to differ depending on species.

The frugivorous “true” fruit fly, Bactrocera tryoni (Queensland fruit fly), is presumed to have a nonresourced-based lek mating system. This is largely untested, and contrary data exists to suggest Bactrocera tryoni may have a resource-based mating system focused on fruiting host plants. We tested the mating system of Bactrocera tryoni, and its close sibling Bactrocera neohumeralis, in large field cages using laboratory reared flies. We used observational experiments that allowed us to determine if: (i) mating pairs were aggregated or nonaggregated; (ii) mating system was resource or nonresource based; (iii) flies utilized possible landmarks (tall trees over short) as mate-rendezvous sites; and (iv) males called females from male-dominated leks. We recorded nearly 250 Bactrocera tryoni mating pairs across all experiments, revealing that: (i) mating pairs were aggregated; (ii) mating nearly always occurred in tall trees over short; (iii) mating was nonresource based; and (iv) that males and females arrived at the mate-rendezvous site together with no evidence that males preceded females. Bactrocera neohumeralis copulations were much more infrequent (only 30 mating pairs in total), but for those pairs there was a similar preference for tall trees and no evidence of a resource-based mating system. Some aspects of Bactrocera tryoni mating behavior align with theoretical expectations of a lekking system, but others do not. Until evidence for unequivocal female choice can be provided (as predicted under a true lek), the mating system of Bactrocera tryoni is best described as a nonresource based, aggregation system for which we also have evidence that land-marking may be involved.

O presente trabalho está vinculado ao Programa de Pós-Graduação em Educação Ambiental - PPGEA/FURG e tem como tema a Educação Ambiental, a Educação Física e os Jogos Cooperativos no contexto escolar, com o objetivo de repensar a prática de Educação Física na escola a partir do desenvolvimento dos jogos cooperativos. A Educação Física é uma disciplina inserida no espaço escolar caracterizada pela presença dos esportes competitivos como conteúdo dominante e a Educação Ambiental é uma prática social que considera outros modos de constituição de relações sociais que estejam para além da lógica perspectivada pelo capitalismo e tão presente na prática dos jogos competitivos realizada nas aulas de Educação Física. A pesquisa insere-se numa perspectiva qualitativa tendo como suporte metodológico a pesquisa-ação. Ocorreu na Escola Municipal de Ensino Fundamental Mate Amargo, onde a pesquisadora possui vínculo. Os sujeitos da pesquisa foram os alunos de uma turma da referida escola e a partir do questionamento ?quais os significados atribuídos aos jogos cooperativos pelos estudantes da turma 71 - sétima série (no ano de 2012 e oitava série em 2013) da Escola Municipal de Ensino Fundamental Mate Amargo, desenvolveu-se esta pesquisa. A produção dos dados ocorreu por meio da proposição de jogos cooperativos e semi-cooperativos com registros escritos dos sujeitos da pesquisa após as vivências, escrita no diário de campo da pesquisadora e a produção de uma história das aulas de Educação Física realizada pelos referidos alunos. Como instrumento de análise foi utilizado a análise textual discursiva (ATD) proposta por Moraes e Galliazzi (2007) o qual se constitui por diversas etapas num movimento recursivo de compreensão do fenômeno investigado. A partir dos dados analisados emergiram duas categorias de análise: a primeira intitula-se ?Jogos e suas múltiplas faces: o resgate do lúdico? onde foi possível analisar as percepções dos alunos diante de tais jogos, os sentimentos que surgiram, suas opiniões e aprendizados. Evidenciouse ainda o potencial lúdico existente nestes jogos propostos. A segunda denomina-se "Entre a competição e a cooperação", e são expressas suas percepções acerca destes dois elementos no jogo, demonstrando que em alguns momentos a competição se evidencia revelando talvez, as próprias vivências dos alunos em seu cotidiano, e por vezes a cooperação se anuncia confirmando a possibilidade desses jogos em impulsionar e desenvolver sentimentos de coletividade, cooperação e sentido de grupo nos sujeitos da pesquisa permitindo o encaminhamento do significado atribuído por eles aos jogos cooperativos como atividades que propiciaram momentos de diversão e prazer, acompanhados de situações em que possibilitou o exercício da cooperação, percepção do outro e da coletividade. Como aporte teórico, deu-se ênfase a autores como Loureiro (2006; 2009), Guimarães (1995;2007), Bracht (1992;2009), Orlick (1978) Brown (2002) Brotto (2001). A pesquisa mostrou que os jogos cooperativos propiciaram a emergência de atitudes cooperativas e a percepção do outro, como também foi possível apreender pelas análises um clima de diversão e prazer sentido e expressado por eles confirmando o potencial lúdico existente nestes jogos.

Social network sites (SNSs) provide new opportunities for online self-presentation of millions of users. The cover profile photograph (CPP) along with written information regarding relationship status is a central component of online self-presentation, although their associations with actual romantic relationships are not clear. We investigated relationships between the presence of a current romantic partner on the CPP and the displayed relationship status and partner satisfaction, partner-directed violence and women's intrasexual competition with peers. A total of 28 % of the 158 women with a Facebook profile and being involved in a romantic relationship had their romantic partners on their CPP. As predicted, women with their partners on the CPP were more satisfied with their romantic relationship than others. Furthermore, women who did not have their partner on the CPP tended to conceal or lie in their displayed mating status suggesting that this may be a strategy how to attract another potential mate. The partner-directed violence and intrasexual competition hypotheses were not supported. Overall, the CPP and an honestly displayed relationship status is an expression of relationship satisfaction amongst women.

Aluminium (Al) toxicity and drought are two major factors limiting common bean (Phaseolus vulgaris) production in the tropics. Short-term effects of Al toxicity and drought stress on root growth in acid, Al-toxic soil were studied, with special emphasis on Al-drought interaction in the root apex. Root elongation was inhibited by both Al and drought. Combined stresses resulted in a more severe inhibition of root elongation than either stress alone. This result was different from the alleviation of Al toxicity by osmotic stress (-0.60 MPa polyethylene glycol) in hydroponics. However, drought reduced the impact of Al on the root tip, as indicated by the reduction of Al-induced callose formation and MATE expression. Combined Al and drought stress enhanced up-regulation of ACCO expression and synthesis of zeatin riboside, reduced drought-enhanced abscisic acid (ABA) concentration, and expression of NCED involved in ABA biosynthesis and the transcription factors bZIP and MYB, thus affecting the regulation of ABA-dependent genes (SUS, PvLEA18, KS-DHN, and LTP) in root tips. The results provide circumstantial evidence that in soil, drought alleviates Al injury, but Al renders the root apex more drought-sensitive, particularly by impacting the gene regulatory network involved in ABA signal transduction and cross-talk with other phytohormones necessary for maintaining root growth under drought.

Mate choice is a primary mechanism driving the evolution of sexually selected traits such as elabo-rate displays and ornaments. In a majority of taxa studied to date, females are seen to actively sampleand evaluate multiple males, presumably to optimize mating opportunities. During this process femalesmay encounter males both familiar and novel, a distinction that might influence how mate choice pro-ceeds. Using a socially monogamous passerine, the blue-black grassquit (Volatinia jacarina), we studiedhow females respond to novel versus familiar (“paired”) males, and how encounters with novel malesinfluence subsequent interactions with their paired males. Additionally, we measured the hormonalresponse of males after visualizing their paired females interacting with novel males. We found thatfemales were attentive to novel males irrespective of these males’ phenotypic attributes, suggesting thatin these interactions novelty is highly relevant. After exposure to novel males, females tended to respondaggressively towards their paired males; by contrast, the behaviour of males towards their paired femalesdid not change. Moreover, we did not detect any hormonal responses of males to viewing their pairedfemales interacting with novel males. Together these results suggest that the distinction between famil-iarity and novelty may hold special relevance for females in mate choice, a finding that bears upon ourunderstanding of the evolution of extra-pair paternity and reproductive behaviour.

Convergencia y divergencia dialectales en los núcleos rurales Redes sociales Actitudes individuales y construcción de estilos personales Existe una tendencia bien conocida en las lenguas hacia la convergencia entre las variedades vernáculas regionales con las prestigiosas y de mayor estatus, propias de los núcleos urbanos y centros culturales. En las comunidades rurales, sin embargo, es más frecuente que tenga lugar una resistencia a la convergencia con el estándar y que se refuerce el uso de los rasgos vernáculos. Lo que ocurre es que el estudio de los procesos de convergencia en los centros urbanos está bien representado en la bibliografía y, sin embargo, son escasos los trabajos que se han ocupado de estudiar las tendencias divergentes en núcleos poblacionales más pequeños y en zonas rurales. De ahí que esta tesis pretenda dar respuesta a ese choque de tendencias convergentes y divergentes que tiene lugar en el ámbito rural. El estudio se centra en dos localidades de la provincia de Málaga, Colmenar y Riogordo, porque ambas reúnen las características idóneas para arrojar un poco de luz sobre este tipo de procesos de contacto dialectal: están cerca de la capital y bien comunicadas con el núcleo urbano, pero a la vez tienen una identidad muy marcada, lo que las convierte en un laboratorio ideal para investigar por qué sus habitantes se inclinan por una u otra variante impulsando, de esta manera, tendencias de convergencia o bien de divergencia con el estándar. Para crear el corpus en el que se basa esta investigación se establecieron cuotas de afijación uniforme basadas en tres variables de preestratificación: sexo, edad y nivel de instrucción. Las casillas de las cuotas se fueron completando por medio del procedimiento de bola de nieve. Para investigar los procesos de divergencia dialectal se han escogido tres variables dependientes, la fricativa velar /x/, la palatal africada /ʧ/ y las líquidas /r/ y /l/ en la distensión silábica. Son buenos indicios para estudiar las tendencias que aquí interesan y, por otra parte, su presencia en la bibliografía sociolingüística no está tan bien representada como la de, por ejemplo, el proceso de escisión de /θs/ en dos unidades, mate y estridente, o su variación en la coda silábica. En el capítulo correspondiente a la variación social se estudia la correlación entre variables dependientes y de preestratificación y también se presta atención a la influencia que ejercen otras variables de postestratificación, como el modo de vida y el grado de formalidad de la situación, porque aportan información relevante sobre la atribución de prestigio patente o encubierto en las localidades rurales. En relación con la variación reticular, se revisa de qué manera interactúan el rango de la red, el sexo y el nivel de estudios de los contactos con las variables dependientes, pues son estos precisamente los indicadores que más fuerza explicativa tienen en la muestra analizada. También interesa conocer qué influencia ejerce en los usos lingüísticos de los hablantes el grado de aceptación de los valores urbanos o su apego a las costumbres locales y su mentalidad rural. Con tal fin se ha construido una Escala de Orientación Urbana, ESORURB, que mide la interacción entre usos lingüísticos y mentalidad del hablante. La tesis se cierra con un estudio de la variación individual según las aportaciones de los trabajos de la tercera ola. Para el análisis se ha escogido a una integrante de una de las redes sociales que sobresale entre su grupo de edad (la segunda generación) y estudios (sociolecto superior) por el alto porcentaje de formas estigmatizadas que emplea. El objetivo del capítulo es detectar qué valor confiere esta hablante a las variantes vernáculas, estudiando los temas de conversación que favorecen su aparición y los marcos discursivos que sirven de contexto. A partir de estos datos se establecen dos estilos conversacionales concretos asociados al empleo de las variantes, y que ella adopta de forma consciente para mostrarse ante los demás y construir una imagen concreta de sí misma.

The structure of an animal’s eye is determined by the tasks it must perform. While vertebrates rely on their two eyes for all visual functions, insects have evolved a wide range of specialized visual organs to support behaviors such as prey capture, predator evasion, mate pursuit, flight stabilization, and navigation. Compound eyes and ocelli constitute the vision forming and sensing mechanisms of some flying insects. They provide signals useful for flight stabilization and navigation. In contrast to the well-studied compound eye, the ocelli, seen as the second visual system, sense fast luminance changes and allows for fast visual processing. Using a luminance-based sensor that mimics the insect ocelli and a camera-based motion detection system, a frequency-domain characterization of an ocellar sensor and optic flow (due to rotational motion) are analyzed. Inspired by the insect neurons that make use of signals from both vision sensing mechanisms, advantages, disadvantages and complementary properties of ocellar and optic flow estimates are discussed.

Benthic marine invertebrates may form metapopulations connected via propagule dispersal. Conservation efforts often target potential source coastlines to indirectly benefit areas depending on allochthonous offspring production. Besides population density, adult size structure, sex ratio, brooding frequency and the proportion of breeding individuals may significantly influence the reproductive output of benthic populations, but these effects have seldom been tested. We used rocky shore crabs to assess the spatial variability of such parameters at relevant scales for conservation purposes and to test their consistency over 2 consecutive years; we then used the data to address whether bottom-up processes or biological interactions might explain the patterns observed. We decomposed egg production rates into their components for the 2 most abundant brachyuran species inhabiting the intertidal rocky habitat. Adult density and brooding frequency varied consistently among shores for both species and largely explained the overall spatial trends of egg production. Temporally consistent patterns also included among-shore differences in the size of ovigerous females of the grapsid Pachygrapsus transversus and between-bay differences in the fecundity of the spider crab Epialtus brasiliensis. Sex ratio was remarkably constant in both. We found no positive or negative correlations between adult density and brooding frequency to support either the existence of a component Allee effect (lack of mate encounters) or an effect of intra-specific competition. Likewise, shore-specific potential growth in P. transversus does not negatively correlate with frequency of ovigerous individuals, as would be expected under a critical balance between these 2 processes. The patterns observed suggest that bottom-up drivers may best explain spatial trends in the reproductive output of these species.

Thirteen international netballers viewed static images of scenarios taken from netball open play. Two ‘team mates’, each marked by one opponent, could be seen in each image; each team mate-opponent pair was located on opposite sides of the vertical meridian, such that a binary response was required (‘left’ or ‘right’) from the participant, in order to select a team mate to whom they would pass the ball. For each trial, a spoken word (“left”/“right”) was presented monaurally at the onset of the visual image. Spatially invalid auditory cues (i.e., in the ear contralateral to the correct passing option), reduced performance accuracy relative to valid ones. Semantically invalid cues (e.g., a call of “left” when the target was right-located), increased response times relative to valid ones. However, there were no accompanying changes in visual attention to the team mates and their markers. The effects of auditory cues on covert attentional shifts and decision-making are discussed.

Sexual selection theory predicts that, in organisms with reversed sex roles, more polyandrous species exhibit higher levels of sexual dimorphism. In the family Syngnathidae (pipefish, seahorses, and seadragons), males provide all parental care by carrying developing embryos on their ventral surfaces, and females develop secondary sex characters. Syngnathids exhibit a variety of genetic mating patterns, making them an ideal group to test predictions of sexual selection theory. Here, we describe the mating system of the black-striped pipefish Syngnathus abaster, using 4 highly variable microsatellites to analyze parentage of 102 embryos. Results revealed that 1) both sexes mate multiple times over the course of a pregnancy (polygynandrous mating system), 2) eggs are spatially segregated by maternity within each brood pouch, and 3) larger females have higher mating success (Kolmogorov–Smirnov test; P < 0.05). Together with similar studies of other syngnathid species, our results support the hypothesis that the mating system is related to the intensity of sexual dimorphism.

El proceso de modernización del Estado ha introducido cambios en los sistemas financieros, operativos, administrativos y de información; por lo que se han emitido nuevas Normas Técnicas de Control Interno, para establecer pautas generales que orienten el accionar de las entidades del sector público, en un adecuado sistema de control interno y probidad administrativa, para el logro de la eficiencia, efectividad, economía y transparencia en la gestión que desarrollan. Para el caso se tratan las NTCIE aplicables al sector de las Municipalidades, y con su entrada en vigencia al ser aprobadas se convierten en base legal para auditar las operaciones y actuaciones financieras internas, por parte de la Corte de Cuentas de la República de El Salvador a dichas entidades y poder comprobar su transparencia ante la ciudadanía. La falta de manuales que contengan procedimientos específicos aplicables a los activos, hace que las instituciones se expongan a efectuar un inadecuado uso y manejo de estos bienes, incluyendo el desconocimiento de la normativa por parte de los involucrados en el proceso de control, y la exposición a fraudes por parte de Concejos Municipales. A esto se le incluye el factor tiempo que es determinante, ya que la normativa señalada por La Corte de Cuentas de la República de El Salvador para las municipalidades, han sido aprobadas y enviadas al diario oficial para su respectiva publicación, momento en el cual serán de aplicabilidad obligatoria para cada institución. Las Municipalidades tienen la necesidad de establecer controles internos apropiados, de manera que den cumplimiento a las Normas Técnicas de Control Internos (NTCIE), y en vista de que no cuentan con los instrumentos que las NTCIE señalan, con el fin de establecer los parámetros de medición, verificación y control para el uso, manejo y salvaguarda de sus Activos Fijos, tampoco cuentan con recursos económicos para la contratación de personal que se dedique a preparar los instrumentos de control interno necesarios por cada área señaladas en las NTCIE de las municipalidades, se diseña el presente Manual de Control Interno para el área del Activo Fijo, habiéndose efectuado un estudio en las Municipalidades que conforman el área metropolitana de San Salvador. Con esto lograremos que las alcaldías del área metropolitana cuenten con políticas y procedimientos de control interno apropiados para verificar el uso, manejo y mantenimiento de sus activos fijos, acordes a la normativa legal que la Corte de Cuentas de la República de El Salvador les ha señalado.
