Gayliella gen. nov in the tribe Ceramieae (Ceramiaceae, Rhodophyta) based on molecular and morphological evidence

On the basis of comparative morphology and phylogenetic analyses of rbcL and LSU rDNA sequence data, a new genus, Gayliella gen. nov., is proposed to accommodate the Ceramium flaccidum complex (C. flaccidum, C. byssoideum, C. gracillimum var. byssoideum, and C. taylorii), C. fimbriatum, and a previously undescribed species from Australia. C. transversale is reinstated and recognized as a distinct species. Through this study, G. flaccida (Kutzing) comb. nov., G. transversalis (Collins et Hervey) comb. nov., G. fimbriata (Setchell et N. L. Gardner) comb. nov., G. taylorii comb. nov., G. mazoyerae sp. nov., and G. womersleyi sp. nov. are based on detailed comparative morphology. The species referred to as C. flaccidum and C. dawsonii from Brazil also belong to the new genus. Comparison of Gayliella with Ceramium shows that it differs from the latter by having an alternate branching pattern; three cortical initials per periaxial cell, of which the third is directed basipetally and divides horizontally; and unicellular rhizoids produced from periaxial cells. Our phylogenetic analyses of rbcL and LSU rDNA gene sequence data confirm that Gayliella gen. nov. represents a monophyletic clade distinct from most Ceramium species including the type species, C. virgatum. We also transfer C. recticorticum to the new genus Gayliella.

Reappraisal of the type species of Polysiphonia (Rhodomelaceae, Rhodophyta)

The genus Polysiphonia Greville, nom. cons., has had a long and confused nomenclatural history. At present, Polysiphonia has a wide circumscription, including at least 200 species, but it is heterogeneous in many vegetative and reproductive developmental features. Central to any re-evaluation of the genus is a detailed examination of the type species of Polysiphonia, P. urceolata (Lightfoot ex Dillwyn) Greville, which is conspecific with P. stricta (Dillwyn) Greville. We here report on the vegetative and reproductive morphology of P. stricta, including P, urceolata, based on type and other material from the British Isles. Thalli consist of prostrate and erect ecorticate axes with four pericentral cells, attached by unicellular rhizoids remaining in open connection with pericentral cells. Prostrate axes lack vegetative trichoblasts; trichoblasts occur seasonally on erect axes. Branch initials are cut off from the subapical cell at intervals of four or five segments in dichotomous and alternating pairs rather than being formed horn each axial cell in the spiral pattern typical of most species of Polysiphonia. Spermatangial branch initials, which are trichoblast homologues, are produced directly from each axial cell at the tips of erect branches, not subtended by trichoblasts, and have two- to five-celled sterile tips when mature. The mature carpogonial branch is four-celled with a two-celled first sterile group and a one-celled second sterile group. Following presumed fertilization, direct fusion apparently takes place between carpogonium and auxiliary tell; mature cystocarps are usually urceolate. Tetrasporangia are formed from the third pericentral cell, in straight series, and have two pre-sporangial cover cells. Previous accounts of a third, post-sporangial cover cell could not be substantiated. P. stricta and a small group of other Polysiphonia species differ in several important respects from most members of the genus, which have rhizoids cut off from pericentral cells by a cell division, abundant trichoblasts, spirally arranged tetrasporangia and a post-sporangial cover cell. The branching pattern of P. stricta highlights the difficulties of distinguishing between the tribes Polysiphonieae and Pterosiphonieae.

Association of Professional Engineers of Ontario records, 1948-1989

The Act to establish the Association of Professional Engineers of Ontario (APEO) was passed on June 14, 1922. The creation of the APEO was part of a larger movement in Canada to license the engineering profession. At first, membership in the APEO was not mandatory in order to work as an engineer, but this changed in 1937 when the Professional Engineers Act was amended so that licensing by the APEO was required. In 1945, the initials “P. Eng.” were adopted by the APEO as the official abbreviation of the professional engineer. Many other amendments have been made over the years in order to strengthen the APEO’s ability to regulate the profession. Members of the APEO must also abide by a Code of Ethics, which emphasizes the regard for public welfare as paramount. There are currently 36 chapters of the APEO. In 1993, the APEO’s name was changed to Professional Engineers of Ontario, in part to emphasize the group’s role as a licensing body for engineers as opposed to an association of member engineers.

World War I Memorial Plaque

World War I Memorial Plaque (17 ½ cm in diameter). This is a bronze plate encased in a 26 ½ cm x 24 cm wooden frame. The inscription on the plate is “He died for freedom and honour, Samuel DeVeaux Woodruff”. [In 1916 the British Government decided to issue a memorial plaque to be given to the relatives of those who died in the Great War. On the plaque is a figure of Britannia who is facing left and holding a laurel wreath over the box where the serviceman’s name is placed. In her right hand she holds a trident which represents Britain’s sea power. There are 2 dolphins facing her on her left and right hand sides. A lion stands in front of her. He faces left with a menacing growl. A very small lion that faces right is located below the larger lion’s feet. He is biting into a winged creature which represents the German Imperial eagle. Near the lion’s right paw there are the initials E CR P which stand for Mr. E. Carter Preston who designed the plate. Some of the plaques include a stamped batch number in front of the lion’s rear left paw. This plaque was produced in batch 17].

Estudio estratégico sectorial aplicado en una empresa social del estado en la ciudad de Bogotá

El estudio sectorial aplicado a una Empresa Social del Estado (E.S.E) en la ciudad de Bogotá, se desarrolló a través de la aplicación de la metodología de análisis estructural de sectores estratégicos a fin de determinar el grado de hacinamiento en el que se encuentra, ubicar las oportunidades que aún no han explotado, conocer el nivel de atractividad del sector e identificar el comportamiento de los competidores para finalmente caracterizar el sector estratégico en términos de los elementos que determinan su comportamiento. Como resultado de las pruebas se evidenciaron cuatro elementos determinantes del comportamiento del sector, ausencia de barreras de entrada propias, existencia de supuestos que limitan la toma de decisiones, existencia de convergencia estratégica y erosión de la estrategia y de la productividad. Estos hallazgos permitieron al equipo de investigación realizar aportes con el fin de generar reflexión estratégica a la E.S.E, ampliar el panorama e implementar innovación conceptual hacia comportamientos diferenciadores que busquen mejorar la cadena de valor.

SIDUR: development of an information system, using controlled vocabulary designed to the characterization and sample of population with and without disability, attended by Rehabilitation programs, University of Rosario

Introduction: the statistical record used in the Field Academic Programs (PAC for it’s initials in Spanish) of Rehabilitation denotes generalities in the data conceptualization, which complicates the reliable guidance in making decisions and provides a low support for research in rehabilitation and disability. In response, the Research Group in Rehabilitation and Social Integration of Persons with Disabilities has worked on the creation of a registry to characterize the population seen by Rehabilitation PAC. This registry includes the use of the International Classification of Functioning, Disability and Health (ICF) of the WHO. Methodology: the proposed methodology includes two phases: the first one is a descriptive study and the second one involves performing methodology Methontology, which integrates the identification and development of ontology knowledge. This article contextualizes the progress made in the second phase. Results: the development of the registry in 2008, as an information system, included documentary review and the analysis of possible use scenarios to help guide the design and development of the SIDUR system. The system uses the ICF given that it is a terminology standardization that allows the reduction of ambiguity and that makes easier the transformation of health facts into data translatable to information systems. The record raises three categories and a total of 129 variables Conclusions: SIDUR facilitates accessibility to accurate and updated information, useful for decision making and research.

Para ello se desarrolló una investigación de tipo documental que permitió identificar el grado de legitimación de los propósitos de la política pública poniendo en perspectiva la intervención de agentes capturadores en el proceso de implementación de la política Agro Ingreso Seguro.

La credibilidad del testimonio infantil ante supuestos de abuso sexual: indicadores psicosociales

La present tesi doctoral estudiarà la temàtica de la credibilitat del relat que els menors presumptament abusats expressen dels fets, en base a l'anàlisi del contingut del seu relat. Fins al moment, la prova que s'utilitza, anomenada CBCA és fonamentalment d'orientació cognitiva, desconsiderant del seu anàlisi, els possibles criteris psicosocials que els menors expressen. Així, la present tesi, a més d'estudiar la prova CBCA, proposa l'utilització d'indicadors psicosocials que, efectivament, són expressats en el relat dels presumptes fets i que, en base a l'anàlisi mètric pertinent, ens permeten presentar-los com a vàlids per a diferenciar relats creíbles, d'aquells relats inventats o falsejats. La part teòrica de la tesi, presenta un exhaustiu recull de les recerques més significatives sobre les següents temàtiques: la credibilitat, l'instrument CBCA, els factors que influeixen en el testimoni infantil i els indicadors psicosocials de credibilitat. La part empírica, en base a un disseny observacional-correlacional i amb una mostra de casos reals treballats a la seu de l'Equip d'Assesorament del Jutjats de Girona, durant els anys 2000-2001, presenta l'estudi i anàlisi del CBCA, criticant les limitacions importants que presenta aquest instrument i, naturalment, proposant l'incorporació dels indicadors psicosocials com a criteris per la diferenciació dels relats. Es realitza un complert anàlisi mètric i es comprova l'increment de la qualitat psicomètrica (fiabilitat, validesa, discriminació de ítems) del nou instrument proposat amb els indicadors psicosocials presentats: el secret, relació dependent-envolvent, progressió en l'abús, normes de conducta, símptomes psicològics, favors i regals.

Generation of nonvernal-obligate, faster-cycling Noccaea caerulescens lines through fast neutron mutagenesis

Noccaea caerulescens (formerly Thlaspi caerulescens) is a widely studied metal hyperaccumulator. However, molecular genetic studies are challenging in this species because of its vernal-obligate biennial life cycle of 7-9 months. Here, we describe the development of genetically stable, faster cycling lines of N. caerulescens which are nonvernal-obligate. A total of 5500 M(0) seeds from Saint Laurent Le Minier (France) were subjected to fast neutron mutagenesis. Following vernalization of young plants, 79 of plants survived to maturity. In all, 80 000 M(2) lines were screened for flowering in the absence of vernalization. Floral initials were observed in 35 lines, with nine flowering in < 12 wk. Two lines (A2 and A7) were selfed to the M(4) generation. Floral initials were observed 66 and 87 d after sowing (DAS) in A2 and A7, respectively. Silicle development occurred for all A2 and for most A7 at 92 and 123 DAS, respectively. Floral or silicle development was not observed in wild-type (WT) plants. Leaf zinc (Zn) concentration was similar in WT, A2 and A7 lines. These lines should facilitate future genetic studies of this remarkable species. Seed is publicly available through the European Arabidopsis Stock Centre (NASC).

The rise and evolution of the cambial variant in Bignonieae (Bignoniaceae)

Cambial variants represent a form of secondary growth that creates great stem anatomical diversity in lianas. Despite the importance of cambial variants, nothing is known about the developmental mechanisms that may have led to the current diversity seen in these stems. Here, a thorough anatomical analysis of all genera along the phylogeny of Bignonieae (Bignoniaceae) was carried out in order to detect when in their ontogeny and phylogeny there were shifts leading to different stem anatomical patterns. We found that all species depart from a common developmental basis, with a continuous, regularly growing cambium. Initial development is then followed by the modification of four equidistant portions of the cambium that reduce the production of xylem and increase the production of phloem, the former with much larger sieve tubes and an extended lifespan. In most species, the formerly continuous cambium becomes disjunct, with cambial portions within phloem wedges and cambial portions between them. Other anatomical modifications such as the formation of multiples of four phloem wedges, multiple-dissected phloem wedges, and included phloem wedges take place thereafter. The fact that each novel trait raised on the ontogenetic trajectory appeared in subsequently more recent ancestors on the phylogeny suggests a recapitulatory history. This recapitulation is, however, caused by the terminal addition of evolutionary novelties rather than a truly heterochronic process. Truly heterochronic processes were only found in shrubby species, which resemble juveniles of their ancestors, as a result of a decelerated phloem formation by the variant cambia. In addition, the modular evolution of phloem and xylem in Bignonieae seems to indicate that stem anatomical modifications in this group occurred at the level of cambial initials.

The project group is participating in a measuring project that is a cooperation between CIT EnergyManagement AB, the Measuring unit of Chalmers and College of Dalarna.The results from the measurementswill be put together and presented in a brochure.When designing the brochure a great deal of planning has been made how to attract the targetgroup.To make the contents of the brochure more attractive, which mainly will contain text, a lot of imageswith a symbolic substance have been used. To keep the brochure together it has been divided into fivechapters that each has been given one specific colour. The colours are consistent on initials, headlinesand images.At the moment the results of the measurements are not yet ready and the text for the brochure is notpossible to complete now. This project is expected to finish in the fall when all the measurements havebeen compiled.

Women's silence : in the space of words and images

My thesis is made up of words and images. This study investigates the way in which silence operates productively within and between the two modes of communication. I suggest that in the process of changing words into images or scripto-visual art-practice, the silence in women's lives can be articulated. I argue that women draw on the generative qualities of silence to create forms of speech that override the cultural constructions of gender which have placed them within the space of ‘mute’ silence. To gain an historical perspective of this practice by women, I consider the lives of medieval nuns within religious enclosure and their work with words and images in the illuminated manuscript. I make a comparative study of original illuminated manuscripts, focussing mainly on visual language and locating aspects of the work closest to my own art-practice: the visual treatment of the space and inter-textual components of the page or folio. This project does not include an examination of miniatures or historiated initials. Rather, its aim is to identify and compare the use of other aesthetic devices available to the medieval scribe/artist through which they might have interacted with the text. I suggest links between verbal and visual performances of language and the repetition, or copying of texts by medieval nuns, as a means of female embodiment of words and their spaces. From the outcomes of my studio investigations and my consideration of other contemporary feminist art practices, I demonstrate how women artists may ‘re-write’ the text and ‘speak’ their silence through visual language and the acts of writing, drawing and painting the words of others. Through my engagement with feminist critical theory, the work of medieval scholars, original illuminated manuscripts and my studio research, I propose that scripto-visual practice remains particularly significant for women despite the differences between the medieval period and our own. As a generative practice, it negotiates some of the societal constraints on women's speech and visibility, because its language is ‘silent and disembodied’ from the image of woman constructed by male discourse. It is a form of speech that acknowledges as it defies the social and cultural conditions that shaped its necessity, articulating an alternative voice of women in the space of words and images.
