Bringing the corporation into corporate branding

Abstract: This paper describes corporate branding as an organisational tool whose successful application depends on attending to the strategic, organisational and communicational context in which it is used A model to help managers analyse context in terms of the alignment between strategic vision, organisational culture and corporate image is presented The model is based on a gap analysis, which enables managers to assess the coherence of their corporate brand Use of the model is illustrated by examining the stages of development that British Airways passed through in the creation of its corporate brand The paper concludes that corporate brand management is a dynamic process that involves keeping up with continuous adjustments of vision, culture and image The model suggests an approach to corporate branding that is organisationally integrated and cross‐functional, hence the thesis that it is important to bring the (whole) corporation into corporate branding

The genome of the protist parasite Entamoeba histolytica

Abstract: Entamoeba histolytica is an intestinal parasite and the causative agent of amoebiasis, which is a significant source of morbidity and mortality in developing countries. Here we present the genome of E. histolytica, which reveals a variety of metabolic adaptations shared with two other amitochondrial protist pathogens: Giardia lamblia and Trichomonas vaginalis. These adaptations include reduction or elimination of most mitochondrial metabolic pathways and the use of oxidative stress enzymes generally associated with anaerobic prokaryotes. Phylogenomic analysis identifies evidence for lateral gene transfer of bacterial genes into the E. histolytica genome, the effects of which centre on expanding aspects of E. histolytica's metabolic repertoire. The presence of these genes and the potential for novel metabolic pathways in E. histolytica may allow for the development of new chemotherapeutic agents. The genome encodes a large number of novel receptor kinases and contains expansions of a variety of gene families, including those associated with virulence. Additional genome features include an abundance of tandemly repeated transfer-RNA-containing arrays, which may have a structural function in the genome. Analysis of the genome provides new insights into the workings and genome evolution of a major human pathogen.

Channel changes in badlands

Abstract: Stripping of the vegetation and soil from a 13-hectare site in Virginia underlain by coastal plain sediments created a rapidly evolving badland topography. Two types of channels developed: (1) sand-bed alluvial channels were graded to transport the bed material load supplied from slope erosion with available runoff, but they also generally eroded their beds slowly, and (2) steeper, bedrock-floored channels incised rapidly. In bedrock channels the erosion rate was proportional to the 4/9ths power of drainage area and the 2/3rds power of gradient. These exponents are consistent with a model in which the erosion rate is proportional to the bed shear during high flows. Due to rapid mass wasting and reduced runoff, the alluvial channels became as much as 50% steeper during the winter than the summer, with an attendant yearly cycle of winter aggradation and summer entrenchment. The gradients, their seasonal variability, and their downstream hydraulic geometry were consistent with the predictions of total load transport formulas for sand beds and high loads. The hydraulic geometry of alluvial channels in the Virginia badlands were similar to that on the Morrison Formation in the western United States.

Shareholder Investment Horizons and the Market for Corporate Control

Abstract: This paper investigates how the investment horizon of a firm's institutional shareholders impacts the market for corporate control. We find that target firms with short-term shareholders are more likely to receive an acquisition bid but get lower premiums. This effect is robust and economically significant: Targets whose shareholders hold their stocks for less four months, one standard deviation away from the average holding period of 15 months, exhibit a lower premium by 3%. In addition, we find that bidder firms with short-term shareholders experience significantly worse abnormal returns around the merger announcement, as well as higher long-run underperformance. These findings suggest that firms held by short-term investors have a weaker bargaining position in acquisitions. Weaker monitoring from short-term shareholders could allow managers to proceed with value-reducing acquisitions or to bargain for personal benefits (e.g., job security, empire building) at the expense of shareholder returns.

The measurement of intra-abdominal pressure as a criterion for abdominal re-exploration

Abstract: Acute elevation of intra-abdominal pressure above 30 mmHg caused oliguria in 11 postoperative patients. Operative re-exploration and decompression in seven patients resulted in immediate diuresis. Four patients who were not re-explored developed renal failure and died. If intra-abdominal pressure rises above 25 mmHg in the early postoperative period and is associated with oliguria and normal blood pressure and cardiac index, the patient should undergo re-exploration and decompression of the abdomen.
