Imagen corporativa del sistema de franquicia en el sector de juegos de loterías
Perozo de Jiménez,Graciela; Montiel Spluga,Lissie;
Revista Venezolana de Gerencia , 2008,
Abstract: the fundamental objective of this article is to evaluate the corporate image of distribution channels operating under the franchise system in the lottery game sector, municipality of maracaibo, zulia, venezuela, from the viewpoint of the outside client made up of sales points. by reviewing the specific stated objectives, the study obtained: perceptions from external clients and user expectations regarding the service rendered, how the corporate image is functioning in the aforementioned system, giving a pragmatic valuation to the image in the management field. research was of the descriptive, field type with a non-experimental, transectional design. the population consisted of 387 sales points (agencies), whole-sale clients of the distribution channels. results indicated that external clients have a favorable perception of the physical or intrinsic attributes of the product associated with the distribution system; nevertheless, regarding extrinsic characteristics, the brand image is not perceived favorably as a fundamental aspect that guarantees needed leverage and backup, and does not achieve recognition and positioning for the product that satisfies external client expectations, centered fundamentally on the profitability margin and support from the brand.
Ultraestructura del bambú Guadua macclurei (Poaceae: Bambusoideae) de Costa Rica
Montiel,Mayra; Guevara,Eric; Jiménez,Víctor M;
Revista de Biología Tropical , 2006,
Abstract: we studied the ultrastructure of sections of leaf lamina, leaf sheath and branches of an adult plant of guadua macclurei. culm sheaths lack fimbriae (oral setae). the adaxial section of the leaf lamina has a particular cellular pattern, previously unreported in this genus. the tricellular trichomes, and the evident and ordered bands of high dome stomata may be useful for taxonomic purposes. to the best of our knowledge, this is the first microscopic description of this species. rev. biol. trop. 54(suppl. 2): 35-42. epub 2006 dec. 01.
Ultraestructura del bambú Guadua amplexifolia (Poaceaea: Bambusoideae) presente en Costa Rica
Montiel,Mayra; Jiménez,Víctor M; Guevara,Eric;
Revista de Biología Tropical , 2006,
Abstract: we used a scanning electron microscope to study the ultrastructure of vegetative and floral parts of guadua amplexifolia from costa rica, a bamboo characterized by a solid culm in the base and a small lumen in the distal part. the most evident characteristics were: epidermic cells with operculated-oblique papillae in the palea, the great amount of ceric papillae forming rosettes in the adaxial section of the leaf blade, the abundance of silica cells in the lemma, the numerous trichomes of the palea and lemma, and the abundance of starch in the parenchymatous tissue. leaves in the particular genotype under study were 7-16 cm long and 3 cm width, while previous studies reported 16-224 cm long and 3-5 cm width for the species. rev. biol. trop. 54(suppl. 2): 21-28. epub 2006 dec. 01.
Caracterización anatómica ultraestructural de las variantes "Atlántica", "Sur" y "Cebolla" del bambú, Guadua angustifolia (Poaceae: Bambusoideae), en Costa Rica
Montiel,Mayra; Jiménez,Víctor M; Guevara,Eric;
Revista de Biología Tropical , 2006,
Abstract: we present an ultrastructural characterization of three variants or "forms" of guadua angustifolia and of the closely related guadua sp., from costa rican populations. their ultrastructure is similar. differences are: the absence of trichomes in the abaxial epidermis of leaf lamina in "cebolla" and hook-shaped trichomes in the lamina of guadua "sur" or "mansa". trichomes were bicellular in "atlántica" or "brava". in the adaxial section of the culm sheaths, "cebolla" lacks trichomes, "sur" has abundant and long unicellular trichomes, and "atlántica" has scarce trichomes (trichomes are an important taxonomic characteristic for differentiation of bamboo variants, and they facilitate genotype identification). the bulliform cells present the following variation: large and segmented in g . "cebolla"; of medium size in g. "sur", and thin and grouped in g. "atlántica". rev. biol. trop. 54(suppl. 2): 1-12. epub 2006 dec. 01.
Ultraestructura del bambú Guadua angustifolia var. bicolor (Poaceae: Bambusoideae), presente en Costa Rica
Montiel,Mayra; Jiménez,Víctor M; Guevara,Eric;
Revista de Biología Tropical , 2006,
Abstract: the anatomy of several parts of guadua angustifolia var. bicolor was analyzed and characterized under a scanning electron icroscope. any similarities ere observed with other guadua species, particularly the presence of high dome stomata, of large cells with sinuous walls and of silica cells. specific bicolor characteristics include (1) a different stomatal pattern in the adaxial zone of the leaf base (close to the sheath); (2) the abundance of hook-sshaped trichomes without papilla; (3) the distinctive golden brown color of the bract that covers the culm (caused by papillar trichomes that cover the adaxial sheath); and (4) the size of the groups of auricular trichomes (formed by 12 trichomes). rev. biol. trop. 54(suppl. 2): 13-19. epub 2006 dec. 01.
Ultraestructura del bambú Guadua paniculata (Poaceae: Bambusoideae) de Costa Rica
Montiel,Mayra; Guevara,Eric; Jiménez,Víctor M;
Revista de Biología Tropical , 2006,
Abstract: sections of leaf lamina, leaf sheath and branches of adult guadua paniculata collected in costa rica, were studied ultrastructurally. diagnostic ultrastructural characteristics include the cellular pattern of the adaxial zone in the leaf blade; the large unicellular trichomes of the abaxial area, the more numerous auricular trichomes, grouped in number of 17, the pattern of cuticular wax and the bands of stomata surrounded by ceric papillae. rev. biol. trop. 54(suppl. 2): 29-34. epub 2006 dec. 01.
Ultraestructura del bambú Guadua macclurei (Poaceae: Bambusoideae) de Costa Rica
Mayra Montiel,Eric Guevara,Víctor M Jiménez
Revista de Biología Tropical , 2006,
Abstract: Se evaluaron ultraestructuralmente secciones de la lámina de la hoja, vaina de la hoja y rama, de una planta adulta de Guadua macclurei. Las brácteas del culmo carecen de setas orales. En la superficie adaxial de la lámina foliar se observó un patrón celular diferente al de otras especies de este género. Además, hay tricomas tricelulares y bandas de estomas de alto domo muy ordenadas y evidentes, característica que la podría diferenciar de otras especies en el género. Esta es la primera descripción microscópica de esta especie. We studied the ultrastructure of sections of leaf lamina, leaf sheath and branches of an adult plant of Guadua macclurei.

The tricellular trichomes, and the evident and ordered bands of high dome stomata may be useful for taxonomic purposes.

Ultraestructura del bambú Guadua angustifolia var. bicolor (Poaceae: Bambusoideae), presente en Costa Rica
Mayra Montiel,Víctor M Jiménez,Eric Guevara
Revista de Biología Tropical , 2006,
Abstract: Se estudió la ultraestructura anatómica de la lámina y la vaina de la hoja, así como de la bráctea del culmo, de Guadua angustifolia var. bicolor, por medio del microscopio electrónico de barrido. Se encontraron similitudes con otras guaduas: estomas de alto domo, células largas con paredes sinuosas y células de sílice. Son propios de la var. bicolor el patrón estomático en la zona abaxial de la hoja cerca de la vaina, con la presencia de gran cantidad de tricomas ganchudos y sin papilas; las brácteas de color café dorado que cubren los culmos y tienen tricomas papilares que cubren el haz; y el abundante número de tricomas auriculares, en grupos de 12. The anatomy of several parts of Guadua angustifolia var. bicolor was analyzed and characterized under a scanning electron icroscope. any similarities ere observed with other Guadua species, particularly the presence of high dome stomata, of large cells with sinuous walls and of silica cells. Specific bicolor characteristics include (1) a different stomatal pattern in the adaxial zone of the leaf base (close to the sheath); (2) the abundance of hook-sshaped trichomes without papilla; (3) the distinctive golden brown color of the bract that covers the culm (caused by papillar trichomes that cover the adaxial sheath); and (4) the size of the groups of auricular trichomes (formed by 12 trichomes).
