Preferencias de los y las estudiantes universitarias sobre el empleo desde una perspectiva de género

2015

Se presenta un estudio de encuesta sobre las preferencias que tiene el alumnado universitario al decidirse por un trabajo, lo que creen que les debe aportar y cómo debe ser la empresa en la que desearían trabajar en función de la variable género. Diferentes investigaciones, señalan que las personas desarrollan valores, expectativas y habilidades profesionales diferentes asociadas a la carrera y a la profesión en función del género. El objetivo de este trabajo es analizar los factores que llevan a los y las jóvenes a percibir  el trabajo o profesión y determinar si dicha percepción es diferente por ser hombre o mujer. A través de un cuestionario ad hoc compuesto por 52 ítems de escala Likert…

Impact of viewing distance on relative depth judgements for stimuli in physical space

2019

In natural viewing, numerous depth cues are available to the visual system, but their significance varies considerably depending on the viewing distance. How is it reflected in the outcome of depth judgements? We have designed a psychophysical experiment with a limited number of depth cues to examine distance-related changes in the correct response rate and time. Twenty young adults evaluated relative depth of stimuli in physical space. Each time four constant angular size achromatic stimuli were presented on a volumetric multi-planar display. One of these stimuli was demonstrated closer to the observer comparing to others. The experiment followed the four-interval forced-choice procedure. …

IMPAIRED ALLOCENTRIC SPATIAL MEMORY UNDERLYNG TOPOGRAPHICAL DISORIENTATION

2006

The cognitive processes supporting spatial navigation are considered in the context of a patient (CF) with possible very early Alzheimer's disease who presents with topographical disorientation. Her verbal memory and her recognition memory for unknown buildings, landmarks and outdoor scenes was intact, although she showed an impairment in face processing. By contrast, her navigational ability, quantitatively assessed within a small virtual reality (VR) town, was significantly impaired. Interestingly, she showed a selective impairment in a VR object-location memory test whenever her viewpoint was shifted between presentation and test, but not when tested from the same viewpoint. We suggest t…

Anxiety and pain perception in patients undergoing mandibular autogenous block bone surgery

2020

Background The aim of the present study was to investigate pain perception and anxiety within the context of surgery for the placement of mandibular block bone and to evaluate the causality effect between theses variables. Material and methods A total of 13 patients were recruited for the study and were submitted to mandibular autogenous block bone surgery. Demographic data were collected and the anxiety level was determined using the State-Trait Anxiety Inventory (STAI). The STAI was administered on the day of surgery and on the 14th postoperative day. Pain was determined using the visual analogue scale (VAS) and limitation of daily activities and postoperative symptoms were also reported.…

A conceptual model of feedback mechanisms in adjusted affordances – Insights from usage of a mental mobile health application

2023

Affordance theory provides one of the most prominent lenses through which the socio-technical aspects of a system’s use can be investigated and understood. In this context, the literature has proposed that perceived and actualized affordances may be adjusted over time. Yet, how the adjustment of affordances occurs has not been explained in detail. Thus, in this article, we develop a conceptual model of feedback mechanisms that includes a more explicit description of how affordances are perceived by users, whether actualized and adjusted. With the model, we introduce the central concept of a generative base, out of which affordance perceptions emerge and which can be updated through affordan…

Psychological State after an Acute Coronary Syndrome: Impact of Physical Limitations

2021

The aim of this study was to investigate how physical limitations after ACS influence patients’ quality of life and health perception. This was a longitudinal clinical study. We recruited 146 patients diagnosed with ACS. The patients performed a stress test (Bruce’s protocol) for the evaluation of physical limitations and were classified according to the test result: without physical limitations (more than 10 METS), with some physical limitations (7 to 9 METS), and with high physical limitations (less than 6 METS). Significant differences were found between the three groups immediately after the diagnosis of ACS and after a period of three months, regarding health perception, anxiety, depre…

High-definition imaging in endoscopic transsphenoidal pituitary surgery.

2011

Background The transsphenoidal approach to sellar lesions has evolved enormously since its first description in the early 20th century. Endoscopic surgical strategies have become an integral part of the surgical armamentarium. More recently, high-definition (HD) digital cameras with better image resolution were introduced, although their value for the surgical procedure remains equivocal. The purpose of this study was to compare the image quality of a standard-definition (SD) camera with a new HD camera. Methods A transsphenoidal pituitary adenomectomy was recorded simultaneously in HD and SD resolution. Eight experienced neurosurgeons were asked to identify predefined as well as not predef…

Youth Athletes' Perception of Existence and Prevalence of Aggression and Interpersonal Violence and Their Forms in Serbia.

2022

Aggression and interpersonal violence (IV) against children and youth are issues in contemporary society. The current study reports on the youth athletes’ perception of the aggression and IV prevalence and its manifestation forms in a Serbian context. The sample included athletes (N = 2091) between the age of 11 and 18 years. Data were collected through an ad-hoc questionnaire created by the authors. Respondents’ answers to introductory questions about the frequency of IV indicated its absence (78.1%). However, the answers to the questions about specific forms of violent peer behavior indicated forms as well as the time and place where IV most often occurs. They underlined that …

Secondary School Students' Knowledge and Opinions on Astrobiology Topics and Related Social Issues.

2017

Astrobiology is the study of the origin of life on Earth and the distribution of life in the Universe. Its multidisciplinary approach, social and philosophical implications, and appeal within the discipline and beyond make astrobiology a uniquely qualified subject for general science education. In this study, student knowledge and opinions on astrobiology topics were investigated. Eighty-nine students in their last year of compulsory education (age 15) completed a written questionnaire that consisted of 10 open questions on the topic of astrobiology. The results indicate that students have significant difficulties understanding the origin of life on Earth, despite exposure to the topic by w…
