Confirmatory factor analysis of an inventory of perception of insecurity and fear of crime

This paper focuses on the study of the factorial structure of an inventory to estimate the subjective perception of insecurity and fear of crime. Made from the review of the literature on the subject and the results obtained in previous works, this factor structure shows that this attitude towards insecurity and fear of crime is identified through a number of latent factors which are schematically summarized in (a) personal safety, (b) the perception of personal and social control, (c) the presence of threatening people or situations, (d) the processes of identity and space appropriation, (e) satisfaction with the environment, and (f) the environmental and the use of space. Such factors are relevant dimensions to analyze the phenomenon. Method: A sample of 571 participants in a neighborhood of Barcelona was evaluated with the proposed inventory, which yielded data from the distributions of all the items provided. The administration was conducted by researchers specially trained for it and the results were analyzed by using standard procedures in the confirmatory factor analysis (CFA) from the hypothesized theoretical structure. The analysis was performed by decatypes according to the different response scales prepared in the inventory and their ordinal nature, and by estimating the polychoric correlation coefficients. The results show an acceptable fit of the proposed model, an appropriate behavior of the residuals and statistically significant estimates of the factor loadings. This would indicate the goodness of the proposed factor structure.

« On m'accuse de discrimination, moi ! » Tout est une histoire de perception

De nos jours, les comportements discriminatoires sont mal vus par la société. On tend à montrer du doigt les personnes s'engageant dans de tels comportements et à médiatiser les entreprises prises en flagrant délit de discrimination, tant au niveau du processus d'embauche (p. ex., rejet systématique des candidatures venant de candidats d'origine étrangère), qu'au niveau des différences de traitement au sein des entreprises (p. ex., différence de salaires entre les femmes et les hommes). Si les comportements discriminatoires sont si mal perçus, pourquoi sont-ils toujours d'actualité ? Comment est-ce que des personnes s'engageant dans de tels comportements peuvent garder à la fois une image positive d'eux-mêmes et éviter de se faire réprimander par d'autres personnes qui pourraient avoir connaissance de leurs mauvais agissements ? C'est à cette problématique que je m'atèle dans ma recherche. A travers une expérience sur le thème de la discrimination à l'embauche, je démontre que les individus ayant tendance à se désengager moralement de leur propre action sont plus à même de s'engager dans des comportements discriminatoires que les autres individus. Le désengagement moral est un processus par lequel les individus justifient leur propre comportement non-éthique afin de les rendre acceptable (Bandura, 1986). En particulier, les résultats ont révélé que cette relation entre désengagement moral et discrimination est modéré par le degré de préjugés des individus. Parmi les individus ayant des préjugés marqués envers les étrangers, plus leur tendance au désengagement moral est élevé, plus ils sont à même de s'engager dans des comportements discriminatoires.

The difference of disease perception by juvenile idiopathic arthritis patients and their parents : analysis of the JAMAR questionnaire.

BACKGROUND: The JAMAR (Juvenile Arthritis Multidimensional Assessment Report) has been developed to evaluate the perception of the patient and his parents on different items: well-being, pain, functional status, quality of life, disease activity, disease course, side effects of medication, therapeutic compliance and satisfaction with illness outcome. Our aim was to compare disease's perception by JIA patients and their parents. METHODS: We included into the study 100 consecutive patients over 7 years of age. We asked both parent and child to complete the JAMAR questionnaire. For each patient we recorded demographic and disease related data. We examined the level of disagreement between children and parents for the quantitative items of the JAMAR: VAS Pain, VAS Disease Activity, VAS Well Being, Juvenile Arthritis Functional Score, HRQoL. Then we looked for a relation between discordance-rate and demographic and clinical variables. RESULTS: Children and parents' median scores for all five items were similar. Individual dyads agreement was low, with a large amount of pairs (80) discordant for at least one item. We found higher MD VAS and JADAS in more discordant dyads, suggesting that when the disease is more active discordance between child and parent increase. CONCLUSION: The JAMAR questionnaire is an important tool that helps clinicians to detect divergent child and parent's disease perceptions. It is essential that both patients and parents fill the JAMAR questionnaire for a complete clinical and psychosocial evaluation.

Étude descriptive quantitative et corrélationnelle portant sur la perception de la qualité de vie des proches aidants de plus de 65 ans qui prennent soin d'un proche souffrant d'une problématique de démence

La problématique : En Suisse, même si l'on constate une longue tradition du modèle de famille pluri-générationnelle multi-locale (Tourollier, 2009), l'évolution démographique a pour effet le vieillissement des aidants (Anchisi, 2010). La société véhicule l'idée que trop de personnes en perte d'autonomie sont abandonnées par leurs familles et que celles-ci relèguent toutes leurs responsabilités à l'Etat. Selon Pitaud (2009), cette vision est erronée, car son étude démontre que les membres de la famille forment généralement le noyau de ce réseau d'aide qui permet leur maintien à domicile. Il s'agit, pour l'auteur, d'une solution à la fois humaine et économiquement acceptable. Le contexte global du vieillissement et de la possibilité de fragilisation psychique suggère qu'une meilleure prise en compte des besoins de l'entourage des personnes souffrants de problématique de démence peut améliorer leur qualité ainsi que celle des proches aidants (Thomas, 2005). But : Cette étude quantitative vise à décrire la perception qu'ont les proches aidants de leur propre qualité de vie incluant leur vulnérabilité. Méthode: Cette étude quantitative descriptive corrélationnelle a été effectuée auprès de 30 proches aidants, recrutés selon un échantillonnage non probabiliste. Pour les corrélations exploratoires, des tests de Pearson, Student, Wilcoxon ou Mann Whitney ont été effectués. Le questionnaire proposé est tiré des études Pixel et il contient des données sociodémographiques, quatre dimensions portant sur la qualité de vie perçue ainsi que deux dimensions sur la vulnérabilité. Résultats: L'âge moyen des proches aidants participant est de 77,47 ans (ÉT 4,74). Les résultats montrent que 40% d'entre eux sont impliqués dans l'aide auprès du malade depuis plus de cinq ans. La plus grande partie a un niveau de formation de type maîtrise professionnelle (70%). Le score moyen de la perception de la qualité de vie (max. 105 points) est de 63.20 (ÉT 10.25). La vulnérabilité perçue est divisée en deux dimensions (max 50 points par partie). Pour la dimension 1 ; la moyenne pour l'impact de la maladie est de 29.00 (ÉT 5.63). Pour la dimension 2 ; la moyenne de l'aggravation de la vulnérabilité, est de 34.26 (ÉT 10.25). Des corrélations exploratoires montrent que l'âge, la durée des soins, le genre sont associées avec une diminution de la qualité de vie ou l'aggravation de la vulnérabilité perçue. Conclusion : Malgré les limites de la présente étude qui sont liées à la petitesse de l'échantillon, les résultats sont conciliables avec les écrits antérieurs. Il serait judicieux de poursuivre des recherches sur ce sujet afin d'approfondir et d'affiner les représentations utiles au renforcement du rôle infirmier auprès des proches aidants d'une part et des autres professionnels du réseau de soin d'autre part, ceci dans le but de favoriser la promotion de la santé auprès des proches aidants qui sont un maillon indispensable dans la chaîne des soins.

Graduating 4th year radiology residents' perception of optimal imaging modalities for neoplasm and trauma: a pilot study from four U.S. universities

OBJECTIVE: Our purpose was to assess 4th year radiology residents' perception of the optimal imaging modality to investigate neoplasm and trauma. MATERIALS AND METHODS: Twenty-seven 4th year radiology residents from four residency programs were surveyed. They were asked about the best imaging modality to evaluate the brain and spine, lungs, abdomen, and the musculoskeletal system. Imaging modalities available were MRI, CT, ultrasound, PET, and X-ray. All findings were compared to the ACR appropriateness criteria. RESULTS: MRI was chosen as the best imaging modality to evaluate brain, spine, abdominal, and musculoskeletal neoplasm in 96.3%, 100%, 70.4%, and 63% of residents, respectively. CT was chosen by 88.9% to evaluate neoplasm of the lung. Optimal imaging modality to evaluate trauma was CT for brain injuries (100%), spine (92.6%), lung (96.3%), abdomen (92.6%), and major musculoskeletal trauma (74.1%); MRI was chosen for sports injury (96.3%). There was agreement with ACR appropriateness criteria. CONCLUSION: Residents' perception of the best imaging modalities for neoplasm and trauma concurred with the appropriateness criteria by the ACR.

New technologies and nursing: use and perception of primary healthcare nurses about electronic health record in Catalonia, Spain

This study was aimed to analyze and assess the use and perception of electronic health records (EHRs) by nurses. The study sample included 113 nurses from different shifts of primary health facilities in Catalonia, Spain, devoted to adult as well as pediatric outpatients using EHRs throughout the year 2010. A majority of the sample (87.5%) were women and 12.5% were men. The average age was 44.27 years and the average time working in primary healthcare was 47.15 months. A majority (80.4%) received specific training on the use of the EHR and 19.6% did not. The use of the application required side technical support (mean: 3.42) and it is considered necessary to learn more about the performance of the application (mean: 3.50). The relationship between the average ratings that nurses have about the EHR and age shows that there is no statistically significant linear relationship (r = - 0.002, p-value = 0.984). As to how long they have used the EHRs, there are significant differences (r= -0.304, p-value = 0.00), so the more time the nurse takes using the EHR, the greater degree of satisfaction is shown. In addition, there are significant differences between nurses" perceptions regarding the EHR and gender (t = - 0.421, p-value = 0.675). Nurses assessed as positive the contribution of the EHRs in their nursing care day work (average score: 2.55/5). Considering that the usability of the EHR device is assessed as satisfactory, the results of the perception of nurses show that we must also take into account the training and emphasize the need for a side technical support in the implementation process of the EHR. Doing so, the positive perception that nurses have in regard to information and communication technology in general and with respect to the EHR in particular may be increased.

Listening to parents: The role of symptom perception in pediatric palliative home care.

OBJECTIVE: This study analyzes symptom perception by parents and healthcare professionals and the quality of symptom management in a pediatric palliative home care setting and identifies which factors contribute to a high quality of palliative and end-of-life care for children. METHODS: In this retrospective, cross-sectional study, parents were surveyed at the earliest three months after their child's death. All children were cared for by a specialized home pediatric palliative care team that provides a 24/7 medical on-call service. Questionnaires assessed symptom prevalence and intensity during the child's last month of life as perceived by parents, symptom perception, and treatment by medical staff. The responses were correlated with essential palliative care outcome measures (e.g., satisfaction with the care provided, quality-of-life of affected children and parents, and peacefulness of the dying phase). RESULTS: Thirty-eight parent dyads participated (return rate 84%; 35% oncological disorders). According to parental report, dyspnea (61%) and pain (58%) were the dominant symptoms with an overall high symptom load (83%). Pain, agitation, and seizures could be treated more successfully than other symptoms. Successful symptom perception was achieved in most cases and predicted the quality of symptom treatment (R 2, 0.612). Concordant assessment of symptom severity between parents and healthcare professionals (HCPs) improved the satisfaction with the care provided (p = 0.037) as well as the parental quality-of-life (p = 0.041). Even in cases with unsuccessful symptom control, parents were very satisfied with the SHPPC team's care (median 10; numeric rating scale 0-10) and rated the child's death as highly peaceful (median 9). Significance of the results: The quality and the concordance of symptom perception between parents and HCPs essentially influence parental quality-of-life as well as parental satisfaction and constitute a predictive factor for the quality of symptom treatment and palliative care.

Perception du timing pubertaire et comportements à risque chez des adolescents suisses

Il faut distinguer timing pubertaire objectif (TPO ; comparaison du timing pubertaire réel d'un sujet avec celui d'un groupe de référence) et timing pubertaire subjectif (TPS ; perception subjective par le sujet de son timing pubertaire par rapport à celui de ses pairs). Chez l'adolescente, la ménarche est couramment utilisée comme marqueur du TPO. La littérature s'intéressant aux variations physiologiques (normales) du timing pubertaire montre qu'un TPO précoce est corrélé chez les adolescentes avec de nombreux problèmes de santé (p.ex. dépression, abus de substances, comportements à risques, niveau d'études inférieur). Un TPO tardif chez l'adolescente serait quant à lui associé à une meilleure réussite scolaire. Les diverses hypothèses expliquant ces corrélations sont brièvement décrites dans notre travail. Certaines hypothèses impliquent des facteurs objectifs tels les changements du corps à la puberté, alors que d'autres privilégient des facteurs plus subjectifs, dans le registre de la perception de soi. A ce jour, la littérature ne s'est que très peu intéressée au TPS en soi. Une adolescente percevant son timing pubertaire comme précoce est-elle à risque même si sa puberté survient objectivement au même âge que la majorité de ses pairs ? L'objectif de ce travail est de rechercher d'éventuelles corrélations entre TPS et adoption de comportements à risque chez des adolescentes rapportant un TPO dans la moyenne. Nos données proviennent de l'enquête SMASH 2002, une étude par questionnaire auto-administré conduite parmi un échantillon de 7548 adolescentes et adolescents suisses âgés de 16-20 ans. Des 3658 adolescentes de l'échantillon initial, nous ne sélectionnons que les 1003 d'entre elles qui ont répondu à la question sur le TPS et qui ont rapporté un âge à la ménarche de 13 ans, soit la moyenne et la médiane de l'âge à la ménarche rapporté par les 3658 adolescentes de l'échantillon initial. Ces 1003 adolescentes sélectionnées sont considérées comme ayant un TPO dans la moyenne. Ces 1003 adolescentes sont séparées en 3 groupes en fonction de leur TPS (précoce/correspondant à la moyenne/tardif). A l'aide d'analyses bivariées et logistiques, nous comparons ces 3 groupes en termes d'adoption de comportements à risque dans le champ de la sexualité (précocité des rapports sexuels) et dans celui de la consommation de substances (tabac, cannabis, drogues dures). Nos résultats montrent principalement qu'une perception de précocité pubertaire est associée avec une précocité des premiers rapports sexuels et de l'usage de drogues dures. A l'inverse, les adolescentes percevant leur puberté comme tardive rapportent moins fréquemment des rapports sexuels avant 16 ans que les adolescentes percevant leur puberté comme dans la moyenne. Les implications cliniques sont les suivantes : face à une adolescente percevant sa puberté comme étant ou ayant été précoce, le praticien devrait investiguer l'existence de comportements à risque même si la puberté survient ou est survenue à un âge similaire à ce qui est retrouvé chez la majorité des pairs. En effet, notre étude suggère que même si cette adolescente se trompe en percevant sa puberté comme précoce, la probabilité de comportements à risque est augmentée dans le champ de la sexualité et de la consommation de substances. Nos résultats suggèrent aussi que l'association retrouvée dans la littérature entre précocité objective de la puberté et comportements à risque chez les adolescentes n'est pas uniquement médiée par les changements corporels pubertaires mais qu'un facteur psychologique tel que la perception subjective est également impliqué.

Individual Perception of Organizational Values

The objective of this master’s thesis was to examine how corporate values come true among the white-collar employees in the case organization. It was also studied if values were perceived similarly in the different departments. Impact of organizational position and education on value orientation was tested through hypotheses based on earlier values research. There are only few value scales available for measuring organizational values. The empirical study results indicate that personnel’s perception of organizational values can be measured statistically. When defining the scale it is utmost important to link the questions and claims close to the employees’ daily working environment. In this study, Work ethic appeared as the strongest organizational value reflecting respondents’ commitment to their duties. Related to corporate values, Performance was perceived as the strongest value and Emphasis on people the weakest. Value consensus between the departments varied. According to the previous research organizational position and educational level has an impact on value perceptions. In this study, employees in superior position or with higher education perceived organizational values to come true better than subordinates or employees with lower education. Empirical data (N=229) was collected by a web-based survey questionnaire among white-collar employees in the case organization in April 2008. Statistical analyses were performed by SPSS programme.

Identidad, percepción de vitalidad etnolingüística y comunicación intergrupal en Cataluña: An identity and ethnolinguistic perception vitality study in Catalonia

Catalan has drawn considerable attention given its impressive institutional support and increased usage since the restoration of the Generalitat of Catalonia. We report a study on 112 Catalan-speaking students who were administered the"subjective vitality questionnaire". Results show (and these are compared with reports 20 years ago) that it continues to gain momentum and status, even with the International stature of Spanish. The theoretical and pragmatic significance of these findings are discussed in terms of vitality"s role in shaping Language choices (Catalan vs. Castilian) in everyday communication as well as the societal level in forging Language policies for communicating in Catalan in business, political, educational, and media arenas

Role of Selected Spectral Attributes in the Perception of Synthetic Vowels

This thesis is an experimental study regarding the identification and discrimination of vowels, studied using synthetic stimuli. The acoustic attributes of synthetic stimuli vary, which raises the question of how different spectral attributes are linked to the behaviour of the subjects. The spectral attributes used are formants and spectral moments (centre of gravity, standard deviation, skewness and kurtosis). Two types of experiments are used, related to the identification and discrimination of the stimuli, respectively. The discrimination is studied by using both the attentive procedures that require a response from the subject, and the preattentive procedures that require no response. Together, the studies offer information about the identification and discrimination of synthetic vowels in 15 different languages. Furthermore, this thesis discusses the role of various spectral attributes in the speech perception processes. The thesis is divided into three studies. The first is based only on attentive methods, whereas the other two concentrate on the relationship between identification and discrimination experiments. The neurophysiological methods (EEG recordings) reveal the role of attention in processing, and are used in discrimination experiments, while the results reveal differences in perceptual processes based on the language, attention and experimental procedure.
