State of South Carolina : Governor Hayne’s message

Governor Hayne speaks of the superiority of individual state sovereignty and states’ rights over mandates by the federal government. Hayne’s speech comes after President Andrew Jackson’s Nullification Proclamation that disputed a state’s right to nullify a federal law, in response to South Carolina’s ordinances declaring the tariff acts of 1828 and 1832 unconstitutional.

Epidemiología y perdurabilidad empresarial en Colombia: Grupo Éxito

La muerte empresarial es un proceso que se ha venido presentando en compañías de las diferentes industrias a nivel nacional. La causa son los diferentes factores externos que impactan directamente las operaciones y estructura de estas. Con base en lo anterior es importante resaltar que existen diferentes tipos de muerte empresarial que para efectos de este trabajo se encontraron importante referenciar, pues son el marco del análisis de caso sobre Almacenes Éxito S.A. perteneciente al sector retail, donde se buscaba determinar cuál fue el tipo de cesión que tuvo, como consecuencia de la venta de acciones a la Compañía Francesa Casino Guichard-Perrachon S.A. Además del marco teórico empleado, se encontró importante realizar una reseña histórica de las diferentes empresas que han integrado el sector con el fin de entender posibles generalidades que se han venido replicando y que han llevado a la muerte empresarial de importantes compañías. Este trabajo permite la comprensión de las diferentes transformaciones que pueden tener los entes económicos a lo largo de su vida empresarial, no solo con lo que puede entenderse como el cese de operaciones sino también como apertura a nuevas estrategias de crecimiento y expansión.

Antineoplasic activity of Copaifera multijuga oil and fractions against ascitic and solid Ehrlich tumor

The aim of this study was to investigate the effect of chronic treatment with C. multijuga oil on Ehrlich tumor evolution. C multijuga was fractionated in a KOH impregnated silica gel column chromatography to give three distinct fractions, i.e., hexanic, chloroformic, and methanolic, mainly composed by hydrocarbon sesquiterpenes, oxygenated sesquiterpenes and acidic diterpenes, respectively. Results demonstrated that the C multijuga oil, the hexanic, and chloroformic fractions did not develop toxic effects. The oil, hexanic and chloroformic fractions (doses varying between 100 and 200 mg/kg) showed antineoplasic properties against Ehrlich ascitic tumor (EAT) and solid tumor during 10 consecutive days of treatment inhibiting ascitic tumor cell number, reverting medulla and blood cell counts to values similar to control group, and inhibiting the increase on several inflammatory mediators (total protein, PGE(2), nitric oxide, and TNF) on ascitic fluid. The treatment also inhibited the increase in paw volume on tumor-inoculated mice. In conclusion, C. multijugo as well as its fractions demonstrated antineoplasic effect even after oral administration confirming its use by traditional medicine. (C) 2008 Elsevier Ireland Ltd.

Bryan the builder-residential work only

The High Court, in the 1995 landmark case of Bryan v Maloney, held a builder of a residential house liable to a subsequent owner for economic loss suffered by way of the reduction in value of the house caused by its defective foundations. Since that decision, several cases in state courts have indicated that any extension of the principle in Bryan to commercial properties is a matter for the High Court. This year, Woolcock Street Investments Pty Ltd v CDG Pty Ltd provided the vehicle for the High Court to revisit the Bryan principle in a commercial context. Faced with the question 'can a subsequent owner of a commercial property who discovers faulty foundations sue the builder for the costs of fixing the problem before it causes any physical damage to person or property?', the resounding response from the High Court has been 'no'. Gleeson CJ, Gummow, Hayne and Heydon JJ in a joint judgment and McHugh J and Callinan J in separate judgements rejected any 'extension' of the Bryan principle to commercial premises. Much to the relief of the construction industry, the Court made it clear that it will be difficult for a subsequent owner to make out a case in negligence against the original builder unless it can show special vulnerability to the risk of injury. Kirby J, in a dissenting judgment, suggested that the extension of liability to commercial builders fits quite comfortably with general principles and lamented the 'incremental' approach to liability presently favoured by the Court. Consequent upon the retirement of Gaudron J, Kirby J appears to be a lonely light on the hill, shining a solitary beacon on matters of principle.

The revisitation of Bryan has long been anticipated. However, Woolcock does not provide the solid bricks and mortar craved by the construction industry. Close examination of the reasoning of the Court suggests that it may itself rest on faulty foundations. In his dissenting judgment, Kirby J questions some of the assumptions made by the majority and highlights the deficiencies of the 'stated case' procedure for a re-examination of this particular area of law, thus suggesting that Woolcock may not be completely sound.

Using internet technology within the organization : a structurational analysis of intranets

Many organizations are implementing Internet technology, specifically Word Wide Web technology, inside the organization in the form of an “organizational Internet” or irttrunet. Intranet technology can unify dispersed computer based information systems in the organization into one rich “system”. Thus, intranets can have a major impact on organizational processes, for example cross-functional information sharing and collaboration. We focus on the social aspects surrounding intranet implementation. We seek to answer how intranet implementations shape and how they are shaped by ‘social structures employed by organizational agents. We adapt structuration theory into an explanatory device to analyze inhanet implementation and we apply it to four cases. We conclude that, intranets are initially more shaped by, rather than shaping social structures, but that this may change over time. The following learning points are condensed: Firstly, intranets are socially constructed and implementers need to be cautious when seeking to transplanting Web technology into an organizational context. Secondly, intranets typically evolve in sophistication over time. Finally, institutionalization is isolated as the key challenge in intranet implementation.

Ontogenesis of the fruit pulp layer of Hymenaea stigonocarpa (Fabaceae : Caesalpinioideae)

Hymenaea, a genus of major economic importance, has been the subject of several botanical studies. However, there is disagreement over the origin of the edible fruit pulp of Hymenaea, as there are no ontogenetic studies on this organ. According to some authors, the edible layer results from transformations of the mesocarp and endocarp, while according to others, it is considered a seed aril. There are still others who regard this layer as originating from an undefined region of the pericarp. To understand the nature and origin of the pulp layer, Hymenaea stigonocarpa Mart. ex Hayne ovaries and fruit were processed according to standard techniques. The production of the fruit pulp layer starts immediately after anthesis. During anthesis, the inner epidermal cells of the ovary show periclinal division and form a new layer of cells towards the mesocarp; this remains meristematic and initiates cell production by predominantly periclinal divisions, producing a compact tissue towards the locule. This tissue will become the fruit pulp layer, the inner endocarp. The seed coat shows typical testal structure without evidence of aril formation. This allows us to conclude that the fruit pulp layers are exclusively made from part of the endocarp. We also observed resin cavities on outer mesocarp and outer endocarp.

Ontogenesis, structure and ultrastructure of Hymenaea stigonocarpa (Fabaceae : Caesalpinioideae) colleters

The genus Hymenaea is characterized by a great diversity of secretory structures, but there are no reports of colleters yet. The objectives of this study are to report the occurrence and describe the origin and structure of colleters in Hymenaea stigonocarpa Mart. ex Hayne. Shoot apex samples were collected, fixed, and processed for light microscopy, scanning electron microscopy, and transmission electron microscopy as per usual methods. Colleters occur predominantly on the stipule's adaxial side. These structures are found at the base on a narrow strip, corresponding to the median vein up to half the length of the stipule. When present on the abaxial side, they are concentrated at the base and restricted to the margins. Colleters develop from the protoderm; they are elongate and club-shaped. Their body has no stratification; their surface cells differ from the inner cells only in position and presence of cuticle. Colleter cells have thin walls, dense cytoplasm, large nuclei, many mitochondria, rough endoplasmic reticulum, and abundant dictyosomes. Histochemical tests with Ruthenium red showed pectic compounds in the cytosol. In H. stigonocarpa, colleter arrangement is compatible with the hypothesis that they protect shoot apex. In this species, protection is reinforced by the sheath formed by the stipule pairs.

Intercellular pectic protuberances in Hymenaea stigonocarpa (Fabaceae, Caesalpinioideae): Occurrence and functional aspects

A study of the anatomy and ultrastructural aspects of leaf mesophyll and floral nectaries of Hymenaea stigonocarpa Mart. ex Hayne revealed the presence of intercellular pectic protuberances (IPPs) linking adjacent cells in both the leaf palisade cells and the secretory parenchyma of the floral nectary. Samples of the middle third of the leaf blade and of floral nectaries in anthesis were collected, fixed, and processed using standard procedures for light, transmission, and scanning electron microscopies. The IPPs of palisade cells of the mesophyll and the secretory parenchyma cells of the floral nectary take the form of scalae or strands, respectively. No evidence of the specific synthesis of these structures was observed, and they are apparently formed by the separation of adjacent cells due to cell expansion, when intercellular spaces develop. The IPPs observed in H. stigonocarpa increase cellular contact and probably act in apoplastic transport.

Diversidade de ácaros (Arachnida: Acari) em Hymenaea martiana (Leguminosae) em gradiente de tamanho de plantas

Foram estudadas as comunidades de ácaros em indivíduos de Hymenaea martiana Hayne (Leguminosae) com diferentes tamanhos, localizados em fragmento de Mata Estacional Semidecidual com transição para o Cerrado. As plantas analisadas foram selecionadas com base no gradiente de altura e perímetro do tronco a 10 cm acima do solo. Foram realizadas coletas quinzenais no período de março de 2007 a março de 2008. em cada amostragem foram retiradas três folhas dos ramos externos e três dos ramos internos, ao redor da região mediana da copa de cada planta selecionada. Para comparar os padrões ecológicos das comunidades de ácaros entre as plantas, foram aplicados índices descritores da diversidade. em H. martiana, foram registrados 109.445 ácaros pertencentes a 28 espécies de 14 famílias. Nove espécies de ácaros, dentre as 19 classificadas como frequentes e acessórias, tiveram sua densidade populacional influenciada pelo tamanho da planta. Enquanto a densidade populacional de Chiapacheylus edentatus de Leon, 1962, Euseius cf. errabundus, Pronematus sp., Brevipalpus phoenicis (Geijskes, 1939) e Tarsonemus sp., apresentou correlação positiva com a altura da planta, a de Aberoptus aff. cerostructor, Euseius sibelius (De Leon, 1962), Typhlodromalus aripo de Leon, 1967 e Phytoseius nahuatlensis de Leon, 1959, apresentou correlação negativa. Não houve influência da altura da planta sobre a riqueza de espécies e densidade total de ácaros entre ramos internos e externos das plantas com diferentes alturas. As variações fisiológicas entre os indivíduos de diferentes estágios ontogenéticos de H. martiana, juntamente com fatores abióticos, podem ter influenciado a ocorrência e a distribuição dessas espécies de ácaros sobre essa planta.
