Effects of masked repetition priming and orthographic neighborhood in visual recognition of words.
1996
Summay.-The role of orthographic neighborhood (neighborhood size and neighborhood Erequency) in visual-word recognition was analyzed using the masked repetition-priming paradigm. Specifically, we varied stimulus-onset asynchrony (33, 50, and 67 msec.) and type of prime (identical, unrelated, unprimed) in a lexical-decision task. Analyses show additive effects of repetition and stimulus-onset asynchrony. Further, the unrelated condition overestimated the repetition effects relative ro an unprimed condition. Fachtatory effects of neighborhood size and inhibitory effects of neighborhood frequency were also found. The results are interpreted in terms of current models of visual-word recognition…
A Brief Measure for the Assessment of Competence in Coping With Death: The Coping With Death Scale Short Version.
2019
Context. The coping with death competence is of great importance for palliative care professionals, who face daily exposure to death. It can keep them from suffering compassion fatigue and burnout, thus enhancing the quality of the care provided. Despite its relevance, there are only two measures of professionals’ ability to cope with death. Specifically, the Coping with Death Scale (CDS) has repeatedly shown psychometric problems with some of its items. Objective. The aim of this study was to develop and validate a short version of the CDS. Methods. Nine items from the original CDS were chosen for the short version. Two cross-sectional surveys were conducted in Spanish (N ¼ 385) and Argent…
Resilience Scale Psychometric Study. Adaptation to the Spanish Population in Nursing Students
2020
Nursing students and professionals are exposed to highly stressful clinical situations. However, when confronted with stress, which is exacerbated by academic and professional situations, there is a great disparity between those who do not know how to respond suitably to the demands from patients or teachers due to a lack of competence and personal resistance, and those who are more resilient and develop a greater range of strengths. This research aims to analyse the validity and psychometric characteristics of a questionnaire on resilience adapted to Spanish nursing bachelor’s degree students. The participants were 434 undergraduate nursing students from the province of Valencia (Spain) be…
Health science student teachers' perceptions of teacher competence: A qualitative study.
2019
Abstract Background Health science teacher competence is multifaceted and continuously changing according to national and international healthcare standards. Organizational restructuring and emphasis on cost effectiveness is changing the scope of health science teachers' practical work and their role in healthcare (worldwide). Aim This study aimed to describe student teachers' perceptions of the competencies needed to work as an educator in the healthcare field. Objective of study was to gain new knowledge which can be used in the development of teacher education programs in nursing science and to define a broader definition of the health science educators. Methods A qualitative study was c…
Nursing Education in Catalonia: Novice Professionals’ Appraisal of Its Quality and Usefulness. Does Mobility Play a Role?
2020
The present study aimed to examine the relationship between the quality of undergraduate education perceived by novice nurses and their retrospective satisfaction with their education. It also studied the relationships between the perceived usefulness of their education for their current jobs and the quality of the jobs held by novice nursing professionals. The moderator role of mobility in this relationship was also analyzed, as it reflects a boundary condition in which additional preparation or job opportunities may occur. The study used data from the graduates’ survey carried out by the Agència per a la Qualitat del Sistema Universitari de Catalunya (AQU) in 2017. The analysis of data fr…
Dopamine D2/3 receptor occupancy by quetiapine in striatal and extrastriatal areas
2010
Quetiapine is next to clozapine an antipsychotic agent that exerts hardly any extrapyramidal side-effects at clinical efficacious doses. Some previous receptor occupancy studies reported preferential extrastriatal D2/3 receptor (D2/3R)-binding properties of second-generation antipsychotics and suggested this as possible reason for improved tolerability. This positron emission tomography (PET) investigation was designed to compare the occupancy of dopamine D2/3Rs by quetiapine in striatal and extrastriatal brain regions. Therefore, a cohort of 16 quetiapine-treated psychotic patients underwent an [18F]fallypride (FP) PET scan. Due to the high affinity of FP and its comparatively long half-li…
The remapping of time by active tool-use
2015
Multiple, action-based space representations are each based on the extent to which action is possible toward a specific sector of space, such as near/reachable and far/unreachable. Studies on tool-use revealed how the boundaries between these representations are dynamic. Space is not only multidimensional and dynamic, but it is also known for interacting with other dimensions of magnitude, such as time. However, whether time operates on similar action-driven multiple representations and whether it can be modulated by tool-use is yet unknown. To address these issues, healthy participants performed a time bisection task in two spatial positions (near and far space) before and after an active …
Prescribers’ opinions to identify competitive groups: a comparative analysis in the pharmaceutical industry
2020
A firm must identify its key competitors (those that belong to the same competitive group), especially when operating in highly competitive industries, such as drug products. Experts who prescribe products to the final consumer play a crucial role in identifying the key competitors of a firm. In this context, the present paper aimed to determine if significant differences exist between two groups of prescribers (commercial and social) regarding the competitive structure that both groups identify using subjective information obtained through (i) categorization methods and (ii) evaluation methods.A sample of 104 prescribers related to the sale of cosmetic pharmaceuticals was interviewed (53 c…
Conocimientos en cuidados paliativos de los profesionales de enfermería de un hospital español
2017
Resume Objective: to determine the level of knowledge in palliative care of nursing staff at a Spanish tertiary care hospital. Method: descriptive, cross-sectional study. Data were collected about the results of the Spanish version of the Palliative Care Quiz for Nurses (PCQN), sociodemographic aspects, education level and experience in the field of palliative care. Univariate and bivariate descriptive analysis was applied. Statistical significance was set at p < 0.05 in all cases. Results: 159 professionals participated (mean age 39.51 years ± 10.25, with 13.96 years ± 10.79 of professional experience) 54.7% possessed experience in palliative care and 64.2% educational background (mainly b…
Brain activity during intra- and cross-modal priming: new empirical data and review of the literature
2003
A positron emission tomography (PET) study was conducted to investigate the neurofunctional correlate of auditory within-modality and auditory-to-visual cross-modality stem completion priming. Compared to the auditory-to-auditory priming condition, cross-modality priming was associated with a significantly larger regional cerebral blood flow (rCBF) decrease at the boundary between left inferior temporal and fusiform gyri, brain regions previously associated with modality independent lexical retrieval and reading. Instead, within-modality auditory priming was associated with a bilateral pattern of prefrontal rCBF increase. This was likely the expression of more efficient access to output lex…
