On the integrability of a new lattice equation found by multiple scale analysis

In this paper we discuss the integrability properties of a nonlinear partial difference equation on the square obtained by the multiple scale integrability test from a class of multilinear dispersive equations defined on a four points lattice

More success than meets the eye: a challenge to critiques of the MBA. Possibilities for critical management education?

Management education generally, and MBA programmes in particular, have been persistently criticized for failing to speak adequately to management practice. One response to such criticisms has been to suggest a wider consideration of critical management education (CME). Drawing on research findings from an empirical study of MBA learning, the article argues that MBA learning can be seen as more valuable to the manager in practice than critics contend. Moreover, the learning which is valued resonates with both a critical understanding of management and critical accounts of the role of management education, suggesting that a covert form of CME may already be operating. We argue that further building on this understanding provides the potential for a more prominent CME. Specifically, we propose that the experience brought to and lived within the MBA programme provides an opportunity for `problematizing' accepted ways of making sense of the world

Exploring MBA career success

Purpose – The purpose of this paper is to examine the meaning of career success in relation to the attainment of an MBA degree, for a group of experienced managers. In so doing, the paper aims to consider the adequacy of MBA career success, defined solely in terms of external criteria. Design/methodology/approach – A total of 36 in-depth interviews were undertaken with MBA alumni which sought to capture the individual's own account of their career success in relation to their MBA. The study utilised an inductive data analysis approach. Findings – The findings revealed a diversity of meanings given to MBA career success, with success generally being expressed in much broader terms than conventional notions of fast track career advancement. The salience of internal criteria for judging MBA career success is thus highlighted. The findings may be seen to further dispel the myth that MBA students are concerned exclusively with status and salary. Research limitations/implications – The study focuses on the experiences of graduates from only one MBA programme. Additionally, the study reports retrospective accounts of MBA career success, a longitudinal design would be advantageous. Practical implications – The demonstration of a plurality of career success provides potential advantage for business schools recruiting MBA students. Organisations can benefit from a wider understanding of MBA career success. Originality/value – The findings suggest that the value of the MBA encompasses more than fast track career success

Event Analysis of Pulse-reclosers in Distribution Systems Through Sparse Representation

The pulse-recloser uses pulse testing technology to verify that the line is clear of faults before initiating a reclose operation, which significantly reduces stress on the system components (e.g. substation transformers) and voltage sags on adjacent feeders. Online event analysis of pulse-reclosers are essential to increases the overall utility of the devices, especially when there are numerous devices installed throughout the distribution system. In this paper, field data recorded from several devices were analyzed to identify specific activity and fault locations. An algorithm is developed to screen the data to identify the status of each pole and to tag time windows with a possible pulse event. In the next step, selected time windows are further analyzed and classified using a sparse representation technique by solving an l1-regularized least-square problem. This classification is obtained by comparing the pulse signature with the reference dictionary to find a set that most closely matches the pulse features. This work also sheds additional light on the possibility of fault classification based on the pulse signature. Field data collected from a distribution system are used to verify the effectiveness and reliability of the proposed method.Comment: Accepted in: 19th International Conference on Intelligent System Application to Power Systems (ISAP), San Antonio, TX, 201

Lax forms of the qq-Painlev\'e equations

All $q$-Painlev\'e equations which are obtained from the $q$-analog of the sixth Painlev\'e equation are expressed in a Lax formalism. They are characterized by the data of the associated linear $q$-difference equations. The degeneration pattern from the $q$-Painlev\'e equation of type $A_2$ is also presented.Comment: 24 page

Orthorexia nervosa and self-attitudinal aspects of body image in female and male university students.

The present study was designed to investigate orthorexia nervosa, or the phenomenon of being preoccupied with consuming healthy food. Specific aims were to explore relationships between orthorexia features and attitudes towards body image, fitness and health in normal weight female and male university students with high levels of healthy food preoccupation, i.e. orthorexia nervosa. METHODS Participants were 327 female (N = 283) and male (N = 44) students aged 18 to 25 years. All participants completed the Polish adaptation of the 15-item questionnaire assessing orthorexia eating behaviours (the ORTHO-15) and the Multidimensional Body-Self Relations Questionnaire (the MBSRQ). Relationships between scores on the ORTHO-15 and MBSRQ were explored in the 213 students who had high levels of preoccupation with a healthy food intake (68.55% women and 43.18% men, respectively). RESULTS: There were no statistically significant differences in the levels of orthorexia behaviours between females and males. In female students with orthorexia nervosa, preoccupation with consuming healthy food was significantly correlated with the MBSRQ subscale scores for overweight preoccupation, appearance orientation, fitness orientation, health orientation, body areas satisfaction and appearance evaluation. Conversely, in male students with orthorexia nervosa there were no correlations between orthorexic behaviours and the MBSRQ subscales. In female students with orthorexia nervosa multivariable linear regression analysis found high body areas (parts) satisfaction, low fitness orientation, low overweight preoccupation and low appearance orientation were independent predictors of greater fixation on eating healthy food. In male students, we found that aspects of body image were not associated with preoccupation with healthy eating. CONCLUSION: A strong preoccupation with healthy and proper food was not associated with an unhealthy body-self relationship among Polish female student with orthorexia nervosa
