Study of adaptation and validation of the Practice environment scale of the nursing work index for the portuguese reality

Objective: Testing the psychometric properties of the Portuguese version of the Practice Environment Scale of the Nursing Work Index. Method: A descriptive, analytical and cross-sectional study, for the cross-cultural adaptation and validation of the psychometric properties of the scale. The study participants were 236 nurses from two hospitals in the regions of Lisbon and Vale do Tejo. Results: The 0.92 Cronbach’s alpha was obtained for overall reliability and support of a five-dimension structure. Conclusion: The excellent quality of adjustment of analysis confirms the validity of the adapted version to hospital care settings, although there was no total coincidence of items in the five dimensions


The Use of virtual reality in the study of people's responses to violent incidents

This paper reviews experimental methods for the study of the responses of people to violence in digital media, and in particular considers the issues of internal validity and ecological validity or generalisability of results to events in the real world. Experimental methods typically involve a significant level of abstraction from reality, with participants required to carry out tasks that are far removed from violence in real life, and hence their ecological validity is questionable. On the other hand studies based on fi eld data, while having ecological validity, cannot control multiple confounding variables that may have an impact on observed results, so that their internal validity is questionable. It is argued that immersive virtual reality may provide a unifi cation of these two approaches. Since people tend to respond realistically to situations and events that occur in virtual reality, and since virtual reality simulations can be completely controlled for experimental purposes, studies of responses to violence within virtual reality are likely to have both ecological and internal validity. This depends on a property that we call"plausibility"- including the fi delity of the depicted situation with prior knowledge and expectations. We illustrate this with data from a previously published experiment, a virtual reprise of Stanley Milgram"s 1960s obedience experiment, and also with pilot data from a new study being developed that looks at bystander responses to violent incidents.

A virtual reality approach to the study of visually driven postural control in developing and aging humans

L'être humain utilise trois systèmes sensoriels distincts pour réguler le maintien de la station debout: la somesthésie, le système vestibulaire, et le système visuel. Le rôle de la vision dans la régulation posturale demeure peu connu, notamment sa variabilité en fonction de l'âge, du type développemental, et des atteintes neurologiques. Dans notre travail, la régulation posturale induite visuellement a été évaluée chez des participants au développement et vieillissement normaux âgés de 5-85 ans, chez des individus autistes (développement atypique) âgés de 12-33 ans, ainsi que chez des enfants entre 9-18 ans ayant subi un TCC léger. À cet effet, la réactivité posturale des participants en réponse à un tunnel virtuel entièrement immersif, se mouvant à trois niveaux de vélocité, a été mesurée; des conditions contrôles, où le tunnel était statique ou absent, ont été incluses. Les résultats montrent que la réactivité (i.e. instabilité) posturale induite visuellement est plus élevée chez les jeunes enfants; ensuite, elle s'atténue pour rejoindre des valeurs adultes vers 16-19 ans et augmente de façon linéaire en fonction de l'âge après 45 ans jusqu'à redevenir élevée vers 60 ans. De plus, à la plus haute vélocité du tunnel, les plus jeunes participants autistes ont manifesté significativement moins de réactivité posturale comparativement à leurs contrôles; cette différence n'était pas présente chez des participants plus âgés (16-33 ans). Enfin, les enfants ayant subi un TCC léger, et qui étaient initialement modérément symptomatiques, ont montré un niveau plus élevé d'instabilité posturale induite visuellement que les contrôles, et ce jusqu'à 12 semaines post-trauma malgré le fait que la majorité d'entre eux (89%) n'étaient plus symptomatiques à ce stade. En somme, cela suggère la présence d'une importante période de transition dans la maturation des systèmes sous-tendant l'intégration sensorimotrice impliquée dans le contrôle postural vers l'âge de 16 ans, et d'autres changements sensorimoteurs vers l'âge de 60 ans; cette sur-dépendance visuelle pour la régulation posturale chez les enfants et les aînés pourrait guider l'aménagement d'espaces et l'élaboration d'activités ajustés à l'âge des individus. De plus, le fait que l'hypo-réactivité posturale aux informations visuelles chez les autistes dépende des caractéristiques de l'environnement visuel et de l'âge chronologique, affine notre compréhension des anomalies sensorielles propres à l'autisme. Par ailleurs, le fait que les enfants ayant subi un TCC léger montrent des anomalies posturales jusqu'à 3 mois post-trauma, malgré une diminution significative des symptômes rapportés, pourrait être relié à une altération du traitement de l'information visuelle dynamique et pourrait avoir des implications quant à la gestion clinique des patients aux prises avec un TCC léger, puisque la résolution des symptômes est actuellement le principal critère utilisé pour la prise de décision quant au retour aux activités. Enfin, les résultats obtenus chez une population à développement atypique (autisme) et une population avec atteinte neurologique dite transitoire (TCC léger), contribuent non seulement à une meilleure compréhension des mécanismes d'intégration sensorimotrice sous-tendant le contrôle postural mais pourraient aussi servir comme marqueurs sensibles et spécifiques de dysfonction chez ces populations. Mots-clés : posture, équilibre, vision, développement/vieillissement sensorimoteur, autisme, TCC léger symptomatique, réalité virtuelle.

Catching Reality or Bowing Disciplines: How to Move the Study of Citizenship

In his contribution, Joppke justifies his selection of foundational scholars by linking each to what he sees as the three key facets of citizenship: status, rights and identity. Maarten Vink explicitly links his research agenda to the first, status, and outlines why it is so important. In identifying three facets of citizenship, Joppke acknowledges that some academics would include political participation, but he ultimately decides against it. But here we can, and should, broaden citizenship studies by bringing in insights from the behavioral politics tradition in domestic politics - when and why people engage in political acts - and from the social movements literature in sociology. I believe that the American debate on immigration reform, admittedly stalled, would not have advanced as far as it has without the social movement activism of DREAMers - unauthorized young people pushing for a path to citizenship - and the belief that Barack Obama won re-election in part because of the Latino vote. Importantly, one type of political activism demands formal citizenship, the other does not. As many contributors note, the “national models” approach has had a significant impact on citizenship studies. Whether one views such models through a cultural, institutional or historical lens, this tends to be a top-down, macro-level framework. What about immigrants’ agency? In Canada, although the ruling Conservative government is shifting citizenship discourse to a more traditional language - as Winter points out - it has not reduced immigration, ended dual citizenship, or eliminated multiculturalism, all goals of the Reform Party that the current prime minister once helped build. “Lock-in” effects (or policy feedback loops) based on high immigrant naturalization and the coming of age of a second-generation with citizenship also d emands study, in North America and elsewhere. Much of the research thus far suggests that political decisions over citizenship status and rights do not seem linked to immigrants’ political activism. State-centered decision-making may have characterized policy in the early post-World War II period in Europe (and East Asia?), but does it continue to hold today? Majority publics and immigrant-origin residents are increasingly politicized around citizenship and immigration. Does immigrant agency extend citizenship status, rights and identity to those born outside the polity? Is electoral power key, or is protest necessary? How is citizenship practiced, and contested, irrespective of formal status? These are important and understudied empirical questions, ones that demand theoretical creativity - across sub-fields and disciplines - in conceptualizing and understanding citizenship in contemporary times.

Nostalgic representation of reality in television fiction: an empirical study based on the analysis of the Spanish television series Cuéntame cómo pasó

The Spanish transition from dictatorship to democracy is often described as an example of negotiation or agreement between the elites (Sánchez Cuenca and Aguilar, 2009: 433). Journalistic and political elites, aware of their important historical role, agreed a consensus on certain issues (democracy, constitution, amnesty) or characters (King Juan Carlos I), in order to ensure the stability of the democratic process (Zugasti, 2007, 2008). Television, which articulates the discourse of the masses, has been one of the basic means used to illustrate the development. Among the highlights of recent major audiovisual content, Cuéntame cómo pasó (2001-present) -a TV-series designed to explain changes with a nostalgic tone in Spanish society since 1968 until today- stands out. By choosing a random sample of episodes for this research we propose to verify the validity of the representation of the political process which contextualizes the series. By analyzing many elements, such as the opinions of the main characters, their personal, political and geographical situations, we try to show the construction of a focal point that sanctifies the official version. We also stress the pacifying and nostalgic tone, which constructs stereotypes and taboos about the process and which characterizes this series as a symbolic culmination of the democratization undertaken by the elites.

The road to augmented reality: a comprehensive study of hardware and applications over the last ten years

Augmented reality has been growing extensively over the years in all aspects and multiple fields. My aim in this paper is to present a comprehensive study on augmented reality(AR) hardware and its applications from early developments to the possible future trends. Particularly my research is more focused on last 11 years(2012-2022), where I systematically reviewed 30 research papers per year to get a clear knowledge on trends of AR. A total of 330 publications were reviewed and grouped according to their application. The review's main contribution is to show the entire landscape of AR research and to provide a broad view of how it has evolved. Along with various AR glasses history and specifications are presented in detail. In the penultimate chapter I explained my methodology of research following my analysis from the past to the present along with my thoughts for the future. To conclude my study, In the final chapter I made some statements about possible future with AR, VR and XR(extended reality).

The study of public administration in India, the Philippines, Canada and Australia: the universal struggle against epistemic colonization, and toward critical assimilation

The study of public administration has been characterized as a strong international focus, as both governments and scholars have sought to learn from the experience of other societies. While in a perfect world, one would expect a sort of pragmatic universalism, instead, many scholars tend to bring lessons from one country, or from a single cultural reality. This modest contribution lies in showing a series of national experiences rarely brought to the discourse about public administration in Brazil: Canada, Australia, India and the Philippines. Special emphasis will be given to the following: the origins and the development of public administration; the influence of ideology; and the complex tension between global theory and local practices.

Environmental sustainability in superior education: case study of Lisbon College of Health Technology

Over the centuries there has been a growing trend of societies and it is possible to verify their economic growth. This growth has provided an increased pressure on natural resources, often over-reaching the boundaries of each country, which has called into question the level of environmental sustainability in different countries. Sustainability is understood as a complex concept involving ecological, social, economic dimensions and temporal urban processes. Therefore, Firmino (2009) suggests that the ecological footprint (EF) allows people to establish dependency relations between human activities and the natural resources required for such activities and for the absorption of waste generated. According to Bergh & Verbruggen (1999) the EF is an objective, impartial and one-dimensional indicator that enables people to assess the sustainability. The Superior Schools have a crucial role in building the vision of a sustainable future as a reality, because in transmitting values and environmental principles to his students, are providing that they, in exercising his professional activity, make decisions weighing the environmental values. This ensures improved quality of life. The present study aims to determine the level of environmental sustainability of the Academic Community of Lisbon College of Health Technology (ESTeSL), by calculating the EF, and describe whether a relation between Footprint and various socio-demographic characteristics of the subjects.

Criteria for the selection of foster families and monitoring of placements.: Comparative study of the application of the Casey Foster Applicant Inventory-Applicant Version (CFAI-A)

Based on a literature review, this article frames different stages of the foster care process, identifying a set of standardized measures in the American and Portuguese contexts which, if implemented, could contribute towards higher levels of foster success. The article continues with the presentation of a comparative study, based on the application of the Casey Foster Applicant Inventory-Applicant Version (CFAI-A) questionnaire, in the aforementioned contexts. Taking a comparative analyses of CFAI-A's psychometric characteristics in four different samples as a starting point, one discovered that despite the fact that the questionnaire was adapted to Portuguese reality, it kept the quality values presented on the American samples. It specifically shows significant values regarding reliability and validity. This questionnaire, which aims to assess the potential of foster families, also supports the technical staff's decision making process regarding the monitoring and support of foster families, while it also promotes a better decision in the placement process towards the child's integration and development.

Biographical narratives in teaching: a study of rofessors on postgraduate courses

Literature and research have shown that professional development constitutes an essential dimension in constructing both work and professional identity. An important aspect in such development is training. In the field of adult education, different authors (Pratt, 1993; Mezirow, 1985; Schön, 1996; Silva, 2007) emphasize the importance of placing trainees at the center of the learning and cognitive processes and within their corresponding social and historical contexts. Training is supported by a comprehensive adult learning theory. Therefore, the acquired knowledge is not only the result of an external and objective reality but also of a complex construction in which the appropriation of experience plays a relevant role. This paper reveals the findings obtained through biographical narratives in a five-year work program with teachers at different levels (from pre-school to higher education) on postgraduate courses. The core issue is the importance of biographical narratives, as an identification strategy for personal experience, knowledge construction and professional identity. This strategy provided the opportunity for recognition of practical experience, as a provider of learning, as well as his/her own authorship, which are important conditions in the understanding of professional identity.

The MicroArray Quality Control (MAQC)-II study of common practices for the development and validation of microarray-based predictive models.

Gene expression data from microarrays are being applied to predict preclinical and clinical endpoints, but the reliability of these predictions has not been established. In the MAQC-II project, 36 independent teams analyzed six microarray data sets to generate predictive models for classifying a sample with respect to one of 13 endpoints indicative of lung or liver toxicity in rodents, or of breast cancer, multiple myeloma or neuroblastoma in humans. In total, >30,000 models were built using many combinations of analytical methods. The teams generated predictive models without knowing the biological meaning of some of the endpoints and, to mimic clinical reality, tested the models on data that had not been used for training. We found that model performance depended largely on the endpoint and team proficiency and that different approaches generated models of similar performance. The conclusions and recommendations from MAQC-II should be useful for regulatory agencies, study committees and independent investigators that evaluate methods for global gene expression analysis.

A Comparative Study of Desktop, Fishtank, and Cave Systems for the Exploration of Volume Rendered Confocal Data Sets

We present a participant study that compares biological data exploration tasks using volume renderings of laser confocal microscopy data across three environments that vary in level of immersion: a desktop, fishtank, and cave system. For the tasks, data, and visualization approach used in our study, we found that subjects qualitatively preferred and quantitatively performed better in the cave compared with the fishtank and desktop. Subjects performed real-world biological data analysis tasks that emphasized understanding spatial relationships including characterizing the general features in a volume, identifying colocated features, and reporting geometric relationships such as whether clusters of cells were coplanar. After analyzing data in each environment, subjects were asked to choose which environment they wanted to analyze additional data sets in - subjects uniformly selected the cave environment.
