Neutrosophic information fusion applied to the options market

In this paper we basically make two propositions - firstly a non-linear process that is primarily fuelled by mass cognitive dissonance could generate systematic deviations between the theoretical and market prices of long-term options, and secondly such deviations are best reconciled in terms of neutrosophic rather than ruled-based reasoning, especially in the context of the users of automated trading systems designed to generate trading signals based on analysis of information  from conflicting sources.

One to one eMarketing strategy alignment: five internet case studies

Despite widespread adoption of new online business models and the rise of online or eMarketing using the Internet (Net) and its current graphical face the World Wide Web (Web), there remains a need for empirical research into specific aspects of eMarketing strategy beyond clickthrough analysis, Web audience analysis and scrutiny of Websites properties to mention the most widely examined elements. This paper discusses Peppers and Rogers (1999) OnetoOne strategy matrix and synthesises their approach with a series of personal interviews with business managers, drawn from a broader empirical study. It does so in an endeavour to improve outcomes from eMarketing strategy and the use of individual Net technologies. The aim is to aid both business practitioner and academician alike in further improving the effectiveness and efficiency gained from using converging technologies in eBusiness.

COSMOS: COmparing standard maternity care with one-to-one midwifery support: a randomised controlled trial

Background: In Australia and internationally, there is concern about the growing proportion of women giving birth by caesarean section. There is evidence of increased risk of placenta accreta and percreta in subsequent pregnancies as well as decreased fertility; and significant resource implications. Randomised controlled trials (RCTs) of continuity of midwifery care have reported reduced caesareans and other interventions in labour, as well as increased maternal satisfaction, with no statistically significant differences in perinatal morbidity or mortality. RCTs conducted in the UK and in Australia have largely measured the effect of teams of care providers (commonly 6–12 midwives) with very few testing caseload (one-to-one) midwifery care. This study aims to determine whether caseload (one-to-one) midwifery care for women at low risk of medical complications decreases the proportion of women delivering by caesarean section compared with women receiving 'standard' care. This paper presents the trial protocol in detail.

Methods/design: A two-arm RCT design will be used. Women who are identified at low medical risk will be recruited from the antenatal booking clinics of a tertiary women's hospital in Melbourne, Australia. Baseline data will be collected, then women randomised to caseload midwifery or standard low risk care. Women allocated to the caseload intervention will receive antenatal, intrapartum and postpartum care from a designated primary midwife with one or two antenatal visits conducted by a 'back-up' midwife. The midwives will collaborate with obstetricians and other health professionals as necessary. If the woman has an extended labour, or if the primary midwife is unavailable, care will be provided by the back-up midwife. For women allocated to standard care, options include midwifery-led care with varying levels of continuity, junior obstetric care and community based general medical practitioner care. Data will be collected at recruitment (self administered survey) and at 2 and 6 months postpartum by postal survey. Medical/obstetric outcomes will be abstracted from the medical record. The sample size of 2008 was calculated to identify a decrease in caesarean birth from 19 to 14% and detect a range of other significant clinical differences. Comprehensive process and economic evaluations will be conducted.

Considerations for performing arts organisations in a climate of transition to the open market context in Vietnam

The emergence of a global economy and culture has created a worldwide climate of change since the 1980s. These changes impact on the growth of a national economy and change the significance of sectors in society, for example the service sector, which increasingly accounts for an important part of the economy (Burbules & Torres, 2000). The arts have also been profoundly influenced by social changes, and technological development. While these changes pose new challenges for the arts, most of which struggle for financial viability in an era of globalisation, privatisation and reduced public funding, the developments also open new opportunities for arts companies/artists but require them to possess the capability to identify and adapt to change. This process underlines the necessary new capacities of arts management, arts marketing, arts leaders and artists.

Doi moi - Vietnamese economic reforms in 1986 - provided impetus for change in every sector, resulting in growth of the service sector in Vietnam (UNDP, 2002). Arts organisations in Vietnam found themselves operating in a more competitive environment, forcing them to adjust to this new economic structure. Improved Vietnamese living standards helped to create more demands for a diverse entertainment industry and allowed both the government and individuals to spend more on the arts. A new cultural policy - socialisation (somewhat equivalent to privatisation in Western countries) was implemented in the arts and cultural sector, producing for performing arts organisations (PAOs) as well as a broader cultural milieu in Vietnam, challenges of being self-sustaining but also more autonomy and greater funding diversity. Simultaneously, this led to upgraded artistic standards, improved infrastructure and higher musicians’ salaries; the latter having only experienced slow improvement during the subsidised era.

This paper investigates how social changes affected organisational operations of selected PAOs in Vietnam and Australia. The analysis of how PAOs in each country adjusted to rapid changes will provide experience for learning from each other, particularly for the Vietnamese case. These analyses provide points of discussion, comparison and implications for development of arts management training in Vietnam. Case studies, personal interviews with key participants and policy actors have been used to discern which direction performing arts management should take in order to correspond with Vietnam’s present and future economic situation and its political position in the world.

Clean technology, willingness to pay and market size

This paper extends Salop’s model of localized competition by introducing the consumers’ willingness to pay (WTP) for clean products and allows an individual firm to choose between a clean or a dirty technology. We assume that a clean technology is relatively costly to adopt. The consumer is willing to pay more for a product produced with clean technology and the model can also be interpreted as a world economy model where each firm represents a country. There exists a critical value of m (proportion of firms adopting the clean technology), m*, such that if m < m* then no country adopts the clean technology, all countries adopt the clean technology only if m > m* while some countries will adopt the clean technology and some will not adopt the clean technology if m = m*. Our results also identify an example of coordination failure. Since symmetric technology adoption delivers the same level of profits as non-adoption, global coordination will be necessary to achieve the clean technology adoption outcome. Finally, we demonstrate that the
private and public (social planner) incentives to adopt clean technology differ.

Representing images by means of interval-valued fuzzy sets. Application to stereo matching

Stereo matching tries to find correspondences between locations in a pair of displaced images of the same scene in order to extract the underlying depth information. Pixel correspondence estimation suffers from occlusions, noise or bias. In this work, we introduce a novel approach to represent images by means of interval-valued fuzzy sets to overcome the uncertainty due to the above mentioned problems. Our aim is to take advantage of this representation in the stereo matching algorithm. The image interval-valued fuzzification process that we propose is based on image segmentation in a different way to the common use of segmentation in stereo vision. We introduce interval-valued fuzzy similarities to compare windows whose pixels are represented by intervals. In the experimental analysis we show the goodness of this representation in the stereo matching problem. The new representation together with the new similarity measure that we introduce shows a better overall behavior with respect to other very well-known methods.
