Attitude of nurses and predisposition to occurrence of adverse events in intensive care units

Objective: to evaluate the attitudes of nurses towards conditions that may predispose to the occurrence of adverse events in the ICU. Method: exploratory, analytical, descriptive, cross-sectional study with quantitative approach performed in six high complexity ICUs of general and teaching hospitals using a convenience sample of 128 nurses. Results: nearly 48% of participants had low perception of risk factors that could predispose to the occurrence of adverse events. There was a significant difference in the attitude of nurses working in public and philanthropic organizations (

Conception, development, and validation of the Behavioral Intentions of Organizational Commitment Scale (BIOCS)

Considering the lack of an organizational commitment measure able to integrate the attitudinal and behavioral perspectives, this study aimed to develop and validate the Behavioral Intentions of Organizational Commitment Scale (BIOCS). BIOCS intends to evaluate the relationship between attitudes and behaviors by studying the behavioral intentions. To better understand the psychometric properties of BIOCS, we selected 1,693 workers in the north, northeast and southern Brazil. Validation procedures adopted by using techniques of both Classical Test Theory and Item Response Theory show BIOCS has a unidimensional structure. From 22 initial items, 20 items met the validation criteria. By presenting suitable psychometric parameters, BIOCS is the first measure of organizational commitment developed and validated to assess behavioral intentions

Construction and content validation of the scale of predisposition to the occurrence of adverse events

This study aimed to present the results of the construction and content validation of the Scale of Predisposition for the Occurrence of Adverse Events (EPEA). A descriptive research with a qualitative approach was carried out. To study the quality of nursing care and design the scale, we performed a literature review that resulted in a preliminary instrument, composed of 90 items, divided into two dimensions to assess the quality of health care (structure and process). Expert analysis and semantic analysis were applied as techniques to study the content validity of the instrument. The findings indicate that the operational version of the EPEA was composed of 64 items, grouped into two dimensions: structure (18 items) and process (46 items). The EPEA is the first Brazilian measure constructed to assess the nurses’ attitudes towards the factors that may predispose to the occurrence of adverse events in ICU

Intention to stay: a component or an outcome of organizational commitment?

The desire to remain in the organization has been considered either as a component of organizational commitment or its outcome. This research aimed to test the influence of both traditional attitudinal variables (affective and continuance basis) and the behavioral intentions to organizational commitment variable on the intention to stay. To test the relationships between these variables, we selected 1,869 workers in the north, northeast and southern Brazil, who filled out a questionnaire. The data were analyzed using multiple regression procedures and structural equation modeling. The results showed that: a) None of the variables constituting the continuance basis predict significantly the measure of intentions to stay, b) Affective basis is the strongest variable predicting the intentions to stay, and c) Behavioral intentions to remain in the organization is not an organizational commitment component

Modelling perceptions on the evaluation of video summarization

Hours of video are uploaded to streaming platforms every minute, with recommender systems suggesting popular and relevant videos that can help users save time in the searching process. Recommender systems regularly require video summarization as an expert system to automatically identify suitable video entities and events. Since there is no well-established methodology to evaluate the relevance of summarized videos, some studies have made use of user annotations to gather evidence about the effectiveness of summarization methods. Aimed at modelling the user’s perceptions, which ultimately form the basis for testing video summarization systems, this paper seeks to propose: (i) A guideline to collect unrestricted user annotations, (ii) a novel metric called compression level of user annotation (CLUSA) to gauge the performance of video summarization methods, and (iii) a study on the quality of annotated video summaries collected from different assessment scales. These contributions lead to benchmarking video summarization methods with no constraints, even if user annotations are collected from different assessment scales for each method. Our experiments showed that CLUSA is less susceptible to unbalanced compression data sets in comparison to other metrics, hence achieving higher reliability estimates. CLUSA also allows to compare results from different video summarizing approaches

Sociological, anthropological and psychological bases for organizational commitment

Organizational commitment is a complex and polysemic construct, and there is no consensus about which definition best describes it. As it is often mistaken for other constructs such as job satisfaction, identification and involvement, few studies have investigated the sociological, anthropological and psychological influences of organizational commitment. Thus, the aim of this paper is to present some social exchange theories, as well as symbol sharing and the relationship between cognitive and social processes, which can provide a better understanding of the individual-organization bonds. A detailed study of some social theories that precede the conception of commitment as an object of study in the field of organizational behavior is substantial to the conceptual clarity of the phenomenon, and indispensable for future studies in discriminant validity as compared to other types of social bonds

Organizational climate: a historical review of the construct

Organizational climate can be characterized as a set of perceptions, shared by workers, of different aspects that make up the organizational environment, being one of the most investigated constructs in the field of Organizational Behavior. This paper aims to organize part of the knowledge produced concerning organizational climate along years, establishing a historical order of research in three stages: from 1930 to 1960, studies of construct taxonomy, context and structure; from 1970 to 1980, distinction between the concepts of organizational climate and culture; and from 1990 on, empirical studies to assess the discriminant validity of organizational climate in relation to other constructs, and development of new analysis methods. The paper emphasizes the urgency of designing new theoretical models to integrate the set of descriptors of existing ones, as well as a wider use of psychometric techniques for the empirical validation of those models

Attitudinal organizational commitment: an empirical research study into the construct dimensionality

The lack of precision surrounding the dimensionality of organizational commitment helps to make it a complex and multifaceted construct. In order to identify the best factor structure for organizational commitment, this study tested the inter-relationship between two attitudinal measures (affective and instrumental) and also the relationship of these variables with a measurement of behavioral intentions. We selected 1,869 workers from the Northern, Northeastern and Southern regions of Brazil. The results of the regression analysis and both the exploratory and confirmatory factor analysis showed the bidimensionality of the instrumental dimension (lack of alternatives and high sacrifices); on the other hand, they demonstrated that this dimension is not part of the factor structure of attitudinal organizational commitment, which in turn is a one dimensional construct, comprising only the affective dimension
