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.

Significance of histological subtypes of Kikuchi`s disease: comparative immunohistochemical and apoptotic studies

Kikuchi's disease (KD) is a self-limiting lymphadenitis mostly affecting the cervical lymph nodes of young individuals. It has been classified into three histological subtypes and postulated to progress from the proliferative type (PT) to the necrotizing type (NT) and finally resolve into the xanthomatous type (XT). Since KD has been shown to be an apoptotic disease, the apoptotic activity was studied by the TUNEL method on 6, 12, and 6 cases of PT, NT, and XT, respectively, to see if the apoptotic activity could be shown to decrease in the order of the postulated sequence of evoluation. Significant statistical difference among the three subtypes was found (P = 0.050). Further analysis revealed that PT versus NT was significant (P = 0.010), but NT versus XT (P = 0.385) or PT versus XT (P = 0.310) was not. Analysis of three stages of NT was also significant (P = 0.019). Immunohistochemical study showed that abundant CD8+ T cells and cytotoxic protein positive cells were present in PT and NT, but were relatively low in XT. Our results showed progression of PT to NT, but not from NT to XT. Xanthomatous type was not the resolving stage of KD, but seemed to be a distinctive histological variant of KD caused by either different etiology or an unusual host reaction.

Faculty collaboration in teaching global business, MBA teaching process

This presentation stems from global business teaching and ongoing research of an interactive group of professors working together in the service delivery of online MBA education at University of Maryland University College . A model for collaborative teaching by delocated professors who literally span the globe – from Australia to Canada, including the United Kingdom, both coasts of the USA, China and Dubai - is offered, underscoring the enormous mobility of knowledge and knowledge workers. Working together as a collaborating team, it was found that the "whole is greater than the sum of the parts". The teachers became more than a teaching team, they became a collaborating operation as they worked together in the sharing and development of materials, insights and knowledge. The model demonstrates how the teaching of global business in an MBA environment is really an exercise in the management of global service operations.

MBA experience by distance education : an ethnographic study of a professional development program

The author's ethnographic study of a professional development program for managers and aspiring managers taught at a distance intends to make a substantial contribution to both the theory and practice of continuing education for professionals. The study focused on a group of Deakin University Master of Business Administration (MBA) participants and their experiences of the final two years of the program. Theorising on the professional development experience was based on data gathered from the direct observation of participants working in their study groups and at residential schools. Moreover, data drawn from end-of-year interviews with participants and discussions with MBA teachers also contributed to the theorising process. Theorising spanned a broad set of interactions encompassing participants' formal educational, professional and personal worlds. The thesis is devoted to two aspects of the professional development experience, namely: participants' interactions in their study groups and at residential schools; and participants' attempts to grow and develop as competent professional practitioners during their MBA studies. Interactions with key learning contexts orchestrated by the teaching institution (i.e. study groups and residential schools) are grounded in an analysis of the changing group cultures observed to accommodate the different educational demands of the program. Group interaction on a broader scale is also analysed in the context of the residential schools. The residential school provided a powerful forum for the development of participant activism over the future development of the MBA program. The analysis of the study groups in action led the author to identify the key characteristics of effective educational work groups. The implications of the success of these essentially egalitarian and leaderless groups for the formation of self-managed groups in the workplace is examined. On the matter of professional development, the author reveals the relationships between the nature of participants' jobs, their search for professional integration, their stage of professional empowerment, the strategies they pursued either to empower themselves or others in their organisations and the barriers which were encountered in the pursuit of empowerment. Dramatic examples of professional disempowerment are analysed indicating that interaction between formal off-the-job learning and professional practice in the workplace is not necessarily a smooth and positive experience. The group of participants studied are seen to be heterogeneous in relation to the above factors characterising professional development The implications of the theorising are considered in relation to professional pedagogies, assessment strategies and distance education. Distance education is seen to socially construct the roles of both teachers and students in the educational process. Specifically, teachers are seen to be somewhat marginalised during the program in use whereas the participants are located at the centre of the educational experience. The primacy of participants in the educational process is highlighted through the growing reliance on self-and peer-group assessment skills as participants progressed through the program. It is argued that the teaching institution should encourage and maintain the development of these skills as they represent a major learning outcome of the professional development experience, i.e. the ability to engage in the process of critical self-reflection and informed action.

Course websites, computer proficiency and need for achievement : implications for MBA student performance

Course websites have become a basic requirement for course promotion and delivery in many universities. This study explores the relationship between perceived usefulness of course websites and student performance in an accounting course within a Masters of Business Administration (MBA) programme. Data from 48 students were found to support several hypotheses. Specifically, the findings of the study indicate that there is a significant correlation between the perceived usefulness of course website features such as lecture notes, tutorial questions and solutions and the frequency of use or access by students of such course website features. Further, we found that the perceived usefulness of course websites was positively related to students’ computer proficiency, but not with the frequency with which students missed classes. The findings also indicate that students with high need for achievement achieved better performance scores, but there was no significant relationship between perceived usefulness of course website and performance. These findings have several implications for the design and development of course websites at post-graduate level, and for future research examining the link between information technology and accounting education.

Online communication of brand personality : a study of MBA programs of top business schools

Brand personality has often been considered from the perspective of products, corporate brands or countries, but rarely among service offerings. Moreover, there remains the consideration of how these entities are communicated online. This article explores the brand personality dimensions that business schools communicate and whether they differ in putting across clear and distinctive brand personalities in cyberspace. Three clusters from the Financial Times' top 100 full-time global MBA programs in 2005 are used to undertake a combination of computerised content and correspondence analyses. The content analysis was structured using Aaker's five-dimensional framework whilst the positioning maps were produced by examining the data using correspondence analysis. Results indicate that some schools have clear brand personalities while others fail to communicate their brand personalities in a distinct way. This study also illustrates a powerful, but simple and relatively inexpensive way for organisations and brand researchers to study the brand personalities actually being communicated.

Subtypes of psychopathy : proposed differences between narcissistic, borderline, sadistic and antisocial psychopaths

Atascadero State Hospital (ASH) is a maximum-security forensic hospital that houses male patients with a wide range of psychiatric diagnoses. Psychopaths at this institution appear to be a heterogeneous group of individuals who, while sharing core personality characteristics, manifest substantial variability in their behavior. Identifying subtypes within this clinical classification can have implications for patient treatment and management, as well as for the safety of the staff who work with them and for the communities to which they will eventually return. Several means of identifying subtypes have been proposed in the literature, and potential subgroups have been identified. Clinical observations at ASH have suggested 4 possible subtypes of psychopathy: narcissistic, borderline, sadistic, and antisocial. Issues related to the conceptualization of psychopathy are addressed, recognizing that additional data are needed to understand the observed variations in cases of psychopathy.

Hub-based reliable gene expression algorithm to classify ER+ and ER- breast cancer subtypes

Identifying gene signatures that are associatedwith the estrogen receptor based breast cancer samples is achallenging problem that has significant implications in breastcancer diagnosis and treatment. Various existing approaches foridentifying gene signatures have been developed but are not ableto achieve the satisfactory results because of their severallimitations. Subnetwork-based approaches have shown to be arobust classification method that uses interaction datasets suchas protein-protein interaction datasets. It has been reported thatthese interaction datasets contain many irrelevant interactionsthat have no biological meaning associated with them, and thusit is essential to filter out those interactions which can improvethe classification results. In this paper, we therefore, proposed ahub-based reliable gene expression algorithm (HRGE) thateffectively extracts the significant biologically-relevantinteractions and uses hub-gene topology to generate thesubnetwork based gene signatures for ER+ and ER- breastcancer subtypes. The proposed approach shows the superiorclassification accuracy amongst the other existing classifiers, inthe validation dataset.

Expression of muscarinic receptor subtypes in tree shrew ocular tissues and their regulation during the development of myopia

Muscarinic receptors are known to regulate several important physiologic processes in the eye. Antagonists to these receptors such as atropine and pirenzepine are effective at stopping the excessive ocular growth that results in myopia. However, their site of action is unknown. This study details ocular muscarinic subtype expression within a well documented model of eye growth and investigates their expression during early stages of myopia induction. Total RNA was isolated from tree shrew corneal, iris/ciliary body, retinal, choroidal, and scleral tissue samples and was reverse transcribed. Using tree shrew-specific primers to the five muscarinic acetylcholine receptor subtypes (CHRM1-CHRM5), products were amplified using polymerase chain reaction (PCR) and their identity confirmed using automated sequencing. The expression of the receptor proteins (M1-M5) were also explored in the retina, choroid, and sclera using immunohistochemistry. Myopia was induced in the tree shrew for one or five days using monocular deprivation of pattern vision, and the expression of the receptor subtypes was assessed in the retina, choroid, and sclera using real-time PCR. All five muscarinic receptor subtypes were expressed in the iris/ciliary body, retina, choroid, and sclera while gene products corresponding to CHRM1, CHRM3, CHRM4, and CHRM5 were present in the corneal samples. The gene expression data were confirmed by immunohistochemistry with the M1-M5 proteins detected in the retina, choroid, and sclera. After one or five days of myopia development, muscarinic receptor gene expression remained unaltered in the retinal, choroidal, and scleral tissue samples. This study provides a comprehensive profile of muscarinic receptor gene and protein expression in tree shrew ocular tissues with all receptor subtypes found in tissues implicated in the control of eye growth. Despite the efficacy of muscarinic antagonists at inhibiting myopia development, the genes of the muscarinic receptor subtypes are neither regulated early in myopia (before measurable axial elongation) nor after significant structural change.
