Resumen tomado de la publicación

MBA – Finanças 1995/97 working paper

O principal objectivo deste estudo centra-se no estudo da influência do capital de risco na performance das empresas que já beneficiaram deste instrumento, procurando assim enriquecer o campo de investigação, ainda incipiente, neste domínio. Tendo como enquadramento o papel daquele instrumento na intermediação financeira, a evolução do sector ao nível internacional e doméstico e sobretudo atendendo aos resultados de análises de estatística multivariada e de clusters efectuadas sobre uma amostra de empresas participadas por capital de risco em Portugal, conclui-se neste estudo que existe efectivamente um impacto relevante da sua intervenção na rentabilidade económica das empresas alvo (ROI), sendo ainda traçado o perfil destas empresa e sugeridas recomendações, não só aos operadores de capital de risco, como também às entidades intervenientes no sector, com especial destaque para o Estado, estas últimas baseadas em posições de entidades nacionais e europeias ligadas ao sector de capital de risco como a APCRI, a EVCA e a própria Comissão Europeia.

Receptor binding profiles of avian influenza virus hemagglutinin subtypes on human cells as a predictor of pandemic potential

The host adaptation of influenza virus is partly dependent on the sialic acid (SA) isoform bound by the viral hemagglutinin (HA). Avian influenza viruses preferentially bind the α-2,3 SA and human influenza viruses the α-2,6 isoform. Each isoform is predominantly associated with different surface epithelial cell types of the human upper airway. Using recombinant HAs and human tracheal airway epithelial cells in vitro and ex vivo, we show that many avian HA subtypes do not adhere to this canonical view of SA specificity. The propensity of avian viruses to adapt to human receptors may thus be more widespread than previously supposed.

Investigating subtypes of reward processing deficits as trait markers for depression

Background: Anhedonia, the loss of pleasure in usually enjoyable activities, is a central feature of major depressive disorder (MDD). The aim of the present study was to examine whether young people at a familial risk of depression display signs of anticipatory, motivational or consummatory anhedonia, which would indicate that these deficits may be trait markers for MDD. Methods: The study was completed by 22 participants with a family history of depression (FH+) and 21 controls (HC). Anticipatory anhedonia was assessed by asking participants to rate their anticipated liking of pleasant and unpleasant foods which they imagined tasting when cued with images of the foods. Motivational anhedonia was measured by requiring participants to perform key presses to obtain pleasant chocolate taste rewards or to avoid unpleasant apple tastes. Additionally, physical consummatory anhedonia was examined by instructing participants to rate the pleasantness of the acquired tastes. Moreover, social consummatory anhedonia was investigated by asking participants to make preference-based choices between neutral facial expressions, genuine smiles, and polite smiles. Results: It was found that the FH+ group’s anticipated liking of unpleasant foods was significantly lower than that of the control group. By contrast, no group differences in the pleasantness ratings of the actually experienced tastes or in the amount of performed key presses were observed. However, controls preferred genuine smiles over neutral expressions more often than they preferred polite smiles over neutral expressions, while this pattern was not seen in the FH+ group. Conclusion: These findings suggest that FH+ individuals demonstrate an altered anticipatory response to negative stimuli and show signs of social consummatory anhedonia, which may be trait markers for depression.

Quantitative Detection of Enterotoxigenic Bacteroides fragilis Subtypes Isolated from Children with and without Diarrhea

A rapid real-time PCR ( RT-PCR) approach was developed to detect the bft gene subtypes in Bacteroides fragilis isolated from fecal samples. DNA obtained from diarrhea (110) and nondiarrhea (150) samples was evaluated. Subtype 1 was observed in 9 (8.2%) diarrhea and 7 (4.7%) nondiarrhea samples. Subtype 2 was not detected in any DNA samples, and subtype 3 was observed in only 1 diarrhea sample. The presence of the bft-1 gene did not show any statistically significant differences between the groups of children. This technique could be used to evaluate a possible correlation between disease and the presence of B. fragilis enterotoxin.

Pricing segmentation and MBA course choice

The consensus from studies of the price-demand relationship for higher education is that this relationship is negative but small. This paper investigates the circumstances in which demand for an MBA is positive to price increases. A survey of currently enrolled MBA students, and prospective MBA students, found that most students displayed the expected price elasticity in a conjoint analysis of hypothetical MBA course ratings. However, 12 per cent of respondents exhibited “reversal” behaviour regarding price. Profiling these respondents using discriminant analysis suggested that “reversals” seemed prepared to pay more for a course at a high prestige university, if they could study off-campus using print-based materials.

Allocative and informational pricing roles in MBA program choice

This paper reports on a study of how prospective and current MBA students (n = 699) made tradeoffs between tuition price and other variables in choosing a university program in the Australian market. Two price segments were identified: price-negative and price-positive. The price-positive segment constituted 13 per cent of the sample. The behaviour of the two price segments is interpreted in relation to the allocative and informational roles of price. Price-positive respondents were found to be more concerned with the reputational characteristics of universities and programs in making their choice. Age, enrolment mode, and residential state were found to be associated with segment membership. The results suggest that an MBA by distance education can be regarded as a prestige product for some market segments.

Tapping global human resources in an MBA teaching team : insights with implications for management education worldwide

It is found that geographic diversity, respect for differing beliefs, encouraging feedback, active participation and interaction with the students, and techniques such as active listening, contribute an architecture and atmosphere to student learning, teacher effectiveness and program excellence in virtual education. One functioning teaching team in University of Maryland University College’s online MBA program provides the action research foundation underpinning the findings. A widely dispersed team of academics and assistants have documented the ways they enhance educational information for students in the program. Assessment activities, supplementary communications and biographical information contribute to student perception of the quality of management education in the program. Mechanisms for effectively tapping a global faculty team are discussed and are informative for administrators and academics alike.

Lifetime cost of stroke subtypes in Australia: findings from the North East Melbourne stroke incidence study (NEMESIS)

Background and Purpose-: Little is known about any variations in resource use and costs of care between stroke subtypes, especially nonhospital costs. The purpose of this study was to describe the patterns of resource use and to estimate the first-year and lifetime costs for stroke subtypes.

Methods-: A cost-of-illness model was used to estimate the total first-year costs and lifetime costs of stroke subtypes for all strokes (subarachnoid hemorrhages excluded) that occurred in Australia during 1997. For each subtype, average cost per case during the first year and the present value of average cost per case over a lifetime were calculated. Resource use data obtained in the North East Melbourne Stroke Incidence Study (NEMESIS) were used.

Results-: The present value of total lifetime costs for all strokes was Aus $1.3 billion (US $985 million). Total lifetime costs were greatest for ischemic stroke (72%; Aus $936.8 million; US $709.7 million), followed by intracerebral hemorrhage (26%; Aus $334.5 million; US $253.4 million) and unclassified stroke (2%; Aus $30 million; US $22.7 million). The average cost per case during the first year was greatest for total anterior circulation infarction (Aus $28 266). Over a lifetime, the present value of average costs was greatest for intracerebral hemorrhage (Aus $73 542), followed by total anterior circulation infarction (Aus $53 020), partial anterior circulation infarction (Aus $50 692), posterior circulation infarction (Aus $37 270), lacunar infarction (Aus $34 470), and unclassified stroke (Aus $12 031).

Conclusions-: First-year and lifetime costs vary considerably between stroke subtypes. Variation in average length of total hospital stay is the main explanation for differences in first-year costs.

Do MBA degrees matter? A study of boards of directors in Australia's top 200 companies

Pfeffer and Fong (2002) suggest that “business school enrolments have soared and business education has become a big business”. The Master of Business Administration (MBA) degree has often been held out to be useful in the career development of managers. The highest level that managers can aspire to, is to be a director of a large public company. This study investigates how many directors within the boards of Australia’s top 200 companies by market capitalization hold an MBA degree. We find that larger companies have proportionally more MBA holding directors than smaller companies. Interestingly we also find that proportionally more women hold MBAs than men; nearly one in five women directors hold an MBA within the top 200 companies dataset.
