The use of correspondence analysis to develop a scale to measure workplace morale from multi-level data

This paper focuses on the issue of comparing social groups or collectivities using measures derived from individual-level multivariate data. In this case, groups need to be differentiated such that: (a) between-group differences are maximized; (b) within-group differences are minimised; and (c) `differences' are calibrated to a scale that reflects a set indicators or observed variables.This paper demonstrates empirically how correspondence analysis can achieve this. It presents a scale of `workplace morale' derived from the responses of employees in a large sample of workplaces to questions concerning satisfaction with various facets of their job and their workplace. The scale derived through correspondence analysis is shown to achieve the three criteria described above.

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.

Accounting for the multidimensional nature of the relationship between adult obesity and socio-economic status : the French second National Individual Survey on Food Consumption (INCA 2) dietary survey (2006–07)

The objective was to study the multidimensional nature of the relationship between adult obesity (OB) and socio-economic status (SES),
using comprehensive indices of SES taken separately or synthesised in an overall index. A nationally representative sample of adults aged
18–79 years was taken from the French second National Individual Survey on Food Consumption (INCA 2) dietary survey (2006–07).
Weight and height were measured and OB defined as BMI $ 30 kg/m². SES variables were reported in questionnaires and included
occupation, education and characteristics of household wealth. Composite indices of SES (household wealth and overall SES indices)
were computed by correspondence analysis, and relationships with OB were investigated with logistic regression analysis. In total, 11·8
(95% CI 10·1, 13·4) % of French adults were obese, without significant difference by sex. While no significant relationship was observed
in men, all SES indicators were inversely correlated to OB in women. Both education and the household wealth index were retained in the
stepwise multivariate model, confirming that different socio-economic variables are not necessarily proxies of each other regarding the OB
issue. On the other hand, ‘controlling for SES’ while including several measures of SES in multivariate models may lead to collinearity, and
thus over-adjustment. A more integrative approach may be to derive a synthetic index by including the SES factors available in a given
study. Beyond this methodological perspective, understanding how OB is related to the different dimensions of SES should help to
target the more vulnerable groups and increase the effectiveness of prevention.

Impact of comorbidities and gender on the use of coronary interventions in patients with high-risk non-ST-segment elevation acute coronary syndrome

OBJECTIVES: To determine the impact of gender and comorbidity on use of coronary interventions in patients diagnosed with high-risk non-ST-segment acute coronary syndrome (NSTEACS). BACKGROUND: Guidelines recommend the use of coronary angiography for all patients diagnosed with NSTEACS with high-risk features, except in the presence of severe comorbidities. However, little is understood about the relationship between gender, comorbidity, and the use of coronary interventions. METHODS: Retrospective analyses of the Victorian Admitted Episodes Data Set (VAED) including all patients diagnosed with NSTEACS with high-risk features on their first admission for ACS between June 2007 and July 2009. Hierarchical logistic regression models and correspondence analyses were used to understand the relationship between gender, comorbidities, and the use of coronary interventions. RESULTS: Out of 16,771 NSTEACS patients with high-risk features, 6,338 (38%) were female. Females were older than males (aged ≥75: 62% vs 39%, p < 0.001) and more likely to have multiple comorbidities (≥2: 66% vs 59%, p < 0.001). After adjusting for potential confounders, females were more likely to receive no coronary intervention than males with a similar number of comorbid conditions (no comorbidities: OR 1.62, 95% CI 1.28-2.05; 1 comorbidity: OR 1.67, 95% CI 1.44-1.93; 2 comorbidities: OR 1.93, 95% CI 1.66-2.23; ≥3 comorbidities: OR 1.42, 95% CI 1.27-1.60). CONCLUSIONS: Lower rates of coronary intervention in females persisted after adjusting for number of comorbidities which suggests that gender may bias decisions regarding referral for coronary intervention in high-risk NSTEACS independent of other factors.

Stereo correspondence estimation using multiwavelets scale-space representation-based multiresolution analysis

A multiresolution technique based on multiwavelets scale-space representation for stereo correspondence estimation is presented. The technique uses the well-known coarse-to-fine strategy, involving the calculation of stereo correspondences at the coarsest resolution level with consequent refinement up to the finest level. Vector coefficients of the multiwavelets transform modulus are used as corresponding features, where modulus maxima defines the shift invariant high-level features (multiscale edges) with phase pointing to the normal of the feature surface. The technique addresses the estimation of optimal corresponding points and the corresponding 2D disparity maps. Illuminative variation that can exist between the perspective views of the same scene is controlled using scale normalization at each decomposition level by dividing the details space coefficients with approximation space. The problems of ambiguity, explicitly, and occlusion, implicitly, are addressed by using a geometric topological refinement procedure. Geometric refinement is based on a symbolic tagging procedure introduced to keep only the most consistent matches in consideration. Symbolic tagging is performed based on probability of occurrence and multiple thresholds. The whole procedure is constrained by the uniqueness and continuity of the corresponding stereo features. The comparative performance of the proposed algorithm with eight famous existing algorithms, presented in the literature, is shown to validate the claims of promising performance of the proposed algorithm.

Relationship between analysis and insight in Mādhyamika Buddhism (a logico-psychological model)

This thesis investigates the relationship between analysis and insight in Prasarigika Madhyamika Buddhism. More specifically it asks whether analysis is a necessary and/or a sufficient condition for the generation of insight. The thesis is divided into six chapters which include an introduction, an appendix which outlines Prasangika and Svatantrika views regarding the syllogism (svatantra) and a conclusion. The remaining chapters seek to demonstrate that analysis for the Prasarigika and the Tibetan Geluk-ba school is a necessary, but not a sufficient condition for the arising of insight. Chapter one is an investigation of certain Western psychological theories which deal with the effects on the mind of cogitating upon contradictions. Though the psychological theories are only suggestive, this chapter will lend support to the claim a) of the Prasaiigika, that analysis generates an altered state of consciousness; and b) that analysis may be a necessary and sufficient condition for the generation of insight. Chapter two seeks to construct a logico-psychological model of how insight is generated. In this model it is argued that insight is a conceptual and intuitive experience: i.e. non-inferential, and that all thought comes via the intuition. This model argues that analysis is a necessary, but not a sufficient condition for the generation of insight. In chapter three an investigation of the writings of Dzong-ka-ba (Tsong-Kha-pa) is undertaken in order to ascertain how the Tibetan Geluk-ba (dGe lugs pa) school regard the relationship between analysis and insight. The model of chapter two will be compared with the Tibetan Geluk-ba accounts to gauge its explanatory power and correspondence with the Geluk-ba views. Chapter four is an investigation of the writings of certain Western scholars. This investigation seeks to ascertain how these scholars may have regarded the relationship between analysis and insight. The chapter then compares these views with the model developed in chapter two.

An analysis of police officers decisions about whether to refer cases of child abuse for prosecution

In many jurisdictions, police officers are responsible for deciding whether cases of child abuse are referred for potential prosecution. Such discretion justifies the need to scrutinise these professionals' decisions to determine if they are consistent with the scientific eyewitness memory literature. Prior research has shown that interviewer questioning is one of the most critical factors impacting the reliability of child witness statements. Hence, we asked: 'To what degree do officers' consider the quality of interviewer questions when making case authorisation decisions?'. In order to answer this question, we conducted a thematic analysis to identify issues referred to in a sample of documented police correspondence (n=33) about potential prosecution of child abuse cases. Two key themes emerged: the existence of corroborative evidence and whether the suspect denied the allegations. Questioning technique, however, was not considered. All but one decision that referred to interview process focused on the presentation of the witness, even though the witness interviews (as a whole) did not adhere to recommended best-practice guidelines. The implications of these findings are discussed.

Wavelets/multiwavelets bases and correspondence estimation problem : an analytic study

Correspondence estimation in one of the most active research areas in the field of computer vision and number of techniques has been proposed, possessing both advantages and shortcomings. Among the techniques reported, multiresolution analysis based stereo correspondence estimation has gained lot of research focus in recent years. Although, the most widely employed medium for multiresolution analysis is wavelets and multiwavelets bases, however, relatively little work has been reported in this context. In this work we have tried to address some of the issues regarding the work done in this domain and the inherited shortcomings. In the light of these shortcomings, we propose a new technique to overcome some of the flaws that could have significantly impact on the algorithm performance and has not been addressed in the earlier propositions. Proposed algorithm uses multiresolution analysis enforced with wavelets/multiwavelts transform modulus maxima to establish correspondences between the stereo pair of images. Variety of wavelets and multiwavelets bases, possessing distinct properties such as orthogonality, approximation order, short support and shape are employed to analyse their effect on the performance of correspondence estimation. The idea is to provide knowledge base to understand and establish relationships between wavelets and multiwavelets properties and their effect on the quality of stereo correspondence estimation.

Law and theology in Gilbert of Foliot's (c. 1105/10-1187/88) correspondence

Lord Peter Stein, eminent historian of Roman law, described the interaction of law and theology in the writings of one twelfth-century writer as a kind of 'universal jurisprudence' , The twelfth-century figure to whom he referred was Master Vacarius (c. 1115/2O-c. 1200), well-known English Roman lawyer and Anglo-Norman canonist. While Stein drew this conclusion largely on the basis of an analysis of Vacatius' strictly 'legal' work, the Liber pauperum, I have shown elsewhere, following a systematic study ofVacarius' other works, dealing with maniage, christology and heresy, that, when seen together, they demonstrate a use of law as a universal heuristic device to resolve conflict in law and theology.

Student self-assessment in higher education: a meta-analysis

Quantitative self-assessment studies that compared self- and teacher marks were subjected to a meta-analysis. Predictions stemming from the results of an earlier critical review of the literature (Boud & Falchikov, 1989) were tested, and salient variables were identified. Factors that seem to be important with regard to the closeness of correspondence between self- and teacher marks were found to include the following: the quality of design of the study (with better designed studies having closer correspondence between student and teacher than poorly designed ones); the level of the course of which the assessment was a part (with students in advanced courses appearing to be more accurate assessors than those in introductory courses); and the broad area of study (with studies within the area of science appearing to produce more accurate self-assessment generally than did those from other areas of study). Results of the analysis are discussed and differences signaled by the results of the three common metrics examined. The distinction between relative and absolute judgment of performance is drawn. It is recommended that researchers give attention to both good design and to adequate reporting of self-assessment studies.
