A multidimensional critical factorization theorem

2005

AbstractThe Critical Factorization Theorem is one of the principal results in combinatorics on words. It relates local periodicities of a word to its global periodicity. In this paper we give a multidimensional extension of it. More precisely, we give a new proof of the Critical Factorization Theorem, but in a weak form, where the weakness is due to the fact that we loose the tightness of the local repetition order. In exchange, we gain the possibility of extending our proof to the multidimensional case. Indeed, this new proof makes use of the Theorem of Fine and Wilf, that has several classical generalizations to the multidimensional case.

Multidimensional Frailty and Vaccinations in Older People: A Cross-Sectional Study

2022

It is known that influenza, herpes zoster, pneumococcal and pertussis infections may increase morbidity and mortality in older people. Vaccinations against these pathogens are effective in older adults. Frailty seems to be an important determinant of vaccination rates, yet data supporting this association are still missing. Therefore, we aimed to investigate the prevalence of four recommended vaccinations (influenza, herpes zoster, pneumococcal and diphtheria-tetanus-pertussis) and the association with multidimensional frailty assessed using a self-reported comprehensive geriatric assessment tool, i.e., the multidimensional prognostic index (SELFY-MPI). Older participants visiting the outpa…

Escala multidimensional aplicada aos estudos de apreciação musical

2009

The multidimensional scaling (MDS) originates from a set of techniques for analyzing proximity of data, which is obtained through the judgments of participants who concomitantly compare several stimuli in various dimensions. The analysis of proximity judgments produces an analysis in which points represent the relationship existent between stimuli in a Euclidean space. The configuration of stimuli in the space defined by these dimensions permits to make inferences about the underlying perceptual universe of the studied group. Literature reveals that MDS is enlarging the study of music and the measurement of its structural properties. La escala multidimensional (MDS) deriva de una familia de…

Multidimensional Analysis of the Distribution of Galaxies with Different Luminosity

1989

We have used the multidimensional or multifractal formalism to study the large scale luminosity segregation of the CfA catalogue. In every sample we have analyzed, it has been found that the spectrum of scaling indices is scale invariant and that bright galaxies are more clustered than faint galaxies.

Development of a short questionnaire based on the Practice Environment Scale-Nursing Work Index in primary health care

2019

BackgroundProfessional nursing environments determine the quality of care and patient outcomes. Assessing the quality of environments is essential to improve and obtain better health outcomes. Simplifying and shortening the way to evaluate environments reliably is also important to help nurses better understand the strengths and weaknesses of their environments. In that sense, identifying essential elements of nursing environments would allow the construction of short assessment tools to improve such environments.ObjectiveTo construct a short tool to assess primary health care (PHC) nursing environments based on the Practice Environment Scale-Nursing Work Index (PES-NWI) questionnaire.Metho…

Black German identities

2009

This study examines the reliability and validity of a German version of the Multidimensional Inventory of Black Identity (MIBI) in a sample of 170 Black Germans. The internal consistencies of all subscales are at least moderate. The factorial structure of the MIBI, as assessed by principal component analysis, corresponds to a high degree to the supposed underlying dimensional structure. Construct validity was examined by analyzing (a) the intercorrelations of the MIBI subscales and (b) the correlations of the subscales with external variables. Predictive validity was assessed by analyzing the correlations of three MIBI subscales with the level of intra-racial contact. All but one predictio…

Weak and Strong Compensation for the Prioritization of Public Investments: Multidimensional Analysis for Pools

2015

Despite the economic crisis still heavily affecting most of Europe, a possible resumption can be found in the revitalization of public and private investments. These investments should be directed not only towards the strategic areas of infrastructures and production, but also to those which allow for a higher level of the quality of life (sports facilities, parks, etc.). In such cases, the need to balance the reasons of financial sustainability with environmental and social profiles is even more evident. Thus, multicriteria techniques, supporting complex assessments, should be implemented together with a monetary feasibility study (cost-benefit analysis). Multidimensional methods allow for…

On the convergent validity of two Parental Rearing Behaviour Scales: EIIBU and PBI

1999

The EMBU and PBI are two of the most used Parental Rearing Behaviour questionnaires. The literature assumes a high correlation between homonymous and assimilable factors (PBI Care and EMBU Affectional Warmth, PBI Control and EMBU Overprotection). Using a sample of 796 subjects the authors carried out the joint application of both scales in order to determine their concurrent validity. The correlation obtained between the scales barely reaches significance on average levels of correlation. The same can be deduced for the applied Multidimensional Scaling. In conclusion, the most extreme precaution is recommended when considering the homonymous scales of both questionnaires, and their joint us…

Assessing mentalization in psychotherapy: first validation of the Mentalization Imbalances Scale

2018

The aim of this study was to provide data on the preliminary validation of a clinician-report multidimensional assessment measure of mentalization (Mentalization Imbalances Scale, MIS). A random national sample of psychotherapists (N=190) completed the MIS to identify mentalization imbalances, and the Personality Disorder Checklist to assess the personality disorders (PDs) of randomly selected patients currently in their care. Factor analysis confirmed the presence of six factors that represented different imbalances of mentalization: cognitive, affective, automatic, external, imbalance toward others, and imbalance toward self. We found several significant relationships between patients’ me…
