Prevalence and associated factors with body image dissatisfaction among adults in southern Brazil: A population-based study

We investigated the prevalence of body image dissatisfaction (BID) and associated factors in Florianopolis, Brazil. BID was analyzed in a sample (N = 1720) of adults through the Figure Rating Scale. The independent variables were sociodemographic factors, health behaviors, and morbidities. A multinomial logistic regression analysis was used. More men (14.2%) than women (6.1%) presented BID by being lighter than ideal (LI). Conversely, more women (66.6%) than men (46.3%) showed BID by being heavier than ideal (HI). BID by being HI was higher among older women, those with high BMI and those with a partner. In men, lower BMI and the presence of common mental disorders were associated with BID due to being LI. Advanced ages, alcohol abuse, physical inactivity, and obesity were associated with BID due to being HI. We must consider different public health interventions for men and women to reduce BID in Brazilian adults.     

The parental attitude research instrument: An approach to use of attitude questionnaires

Parental attitude questionnaires such as the Parental Attitude Research Instrument (PARI) are still in use despite their inherent difficulties. In light of the need to test theoretical models by measuring a range of parental characteristics, the properties of the PARI were re-examined and, on the basis of a factor analysis of the 23 subtests of the PARI, a shortened version was constructed. A measure of maternal Authoritarian Control, which was found to be associated with measures of maternal mental ability, personality, level of education, reading age, number of adverse family conditions and child-rearing practices, has proved useful for other projects related to this ongoing study. It is recommended that such instruments be used only in conjunction with other measures which examine the family environment, for example in an index of child-rearing practices.     

Self-forgiveness and forgiveness-seeking in response to rumination: Cardiac and emotional responses of transgressors

Self-forgiveness and forgiveness-seeking are important and understudied aspects of forgiveness. We examined the cardiac and emotional patterns of healthy young adults (40 women, 40 men) who recalled an unresolved offense they had caused another person. Participants engaged in four imagery conditions: ruminating about the offense, being humbly repentant and engaging in self-forgiveness, seeking forgiveness from the victim and receiving forgiveness, and seeking forgiveness from the victim and being begrudged. Being repentant and begrudged forgiveness by one’s victim was associated with the same level of guilt as when ruminating, but significantly more negative emotion, less control, and less empathy than when ruminating, self-forgiving, and receiving forgiveness from the victim. Compared to ruminating about one’s wrongdoing, self-forgiving alleviated guilt and negative emotion, increased perceived control, decreased heart rate, and increased parasympathetic activation. Imagery of receiving forgiveness from the victim resulted in these same patterns and was equivalent to self-forgiveness across variables.     

On the Ethics of Democratic Access to Web Information

Floridi’s work, although diverse and multifaceted, portrays a solid coherence across his different lines of work. Among his wealth of interests and results, we highlight his recent work on information logics, on the ethics of information technology, and his rigorous (and vigorous) philosophical analysis of recent technological trends and developments in information technology. In the present article we illustrate, by means of some connecting arguments, the diversity and coherence of Floridi’s work. We also show how his work, although fundamentally philosophical in nature, can be used to build solid foundations for scientific and entrepreneurial endeavours of higher quality. More specifically, we discuss how the combination of results from the three lines of work referred to above can be used as ground for the organisation of higher quality programmes to augment the capabilities and effectiveness of governmental systems through information and communications technology, a trend that has been explored in many nations and that has been coined Electronic Government. Electronic Government programmes that improve the capabilities of citizens to interact with each other and with governments, as well as the capabilities of governments to listen to the needs and aspirations of citizens, have the potential to contribute to the construction of more democratic states. Electronic Government systems that rely on ready made models to prescribe to citizens how best they should interact with each other and with the public administration are, however, by construction non-democratic. Hence, it can be a moral and ethical matter for governments to choose which line of technological development they take.     

Marital Relationship,Body Image and Psychological Quality of Life among Breast Cancer Patients: The Moderating Role of the Disease’s Phases

In this cross-sectional study we analyzed the links between marital quality and intimacy, body image, and psychological quality of life (PQoL) of breast cancer patients, as well as the moderating role of cancer phase (treatment, survivorship) on the aforementioned links. We also evaluated whether body image mediated the associations between marital relationship variables and PQoL. An analysis of the data from 128 patients (66 undergoing treatment, 62 survivors) indicated that the majority of links between variables were significant only during the treatment phase. Mediating effect of body image on the associations between relationship variables and PQoL was found only at the treatment phase.     

Conditioned fear is modulated by D2 receptor pathway connecting the ventral tegmental area and basolateral amygdala

Excitation of the mesocorticolimbic pathway, originating from dopaminergic neurons in the ventral tegmental area (VTA), may be important for the development of exaggerated fear responding. Among the forebrain regions innervated by this pathway, the amygdala is an essential component of the neural circuitry of conditioned fear. The functional role of the dopaminergic pathway connecting the VTA to the basolateral amygdala (BLA) in fear and anxiety has received little attention. In vivo microdialysis was performed to measure dopamine levels in the BLA of Wistar rats that received the dopamine D(2) agonist quinpirole (1 μg/0.2 μl) into the VTA and were subjected to a fear conditioning test using a light as the conditioned stimulus (CS). The effects of intra-BLA injections of the D(1) antagonist SCH 23390 (1 and 2 μg/0.2 μl) and D(2) antagonist sulpiride (1 and 2 μg/0.2 μl) on fear-potentiated startle (FPS) to a light-CS were also assessed. Locomotor performance was evaluated by use of open-field and rotarod tests. Freezing and increased dopamine levels in the BLA in response to the CS were both inhibited by intra-VTA quinpirole. Whereas intra-BLA SCH 23390 did not affect FPS, intra-BLA sulpiride (2 μg) inhibited FPS. Sulpiride's ability to decrease FPS cannot be attributed to nonspecific effects because this drug did not affect motor performance. These findings indicate that the dopamine D(2) receptor pathway connecting the ventral tegmental area and the basolateral amygdala modulates fear and anxiety and may be a novel pharmacological target for the treatment of anxiety.     

One-dimensional and multi-dimensional studies of the exocentric distance estimates in frontoparallel plane, virtual space, and outdoor open field

The aim of this study is twofold: on the one hand, to determine how visual space, as assessed by exocentric distance estimates, is related to physical space. On the other hand, to determine the structure of visual space as assessed by exocentric distance estimates. Visual space was measured in three environments: (a) points located in a 2-D frontoparallel plane, covering a range of distances of 20 cm; (b) stakes placed in a 3-D virtual space (range = 330 mm); and (c) stakes in a 3-D outdoors open field (range = 45 m). Observers made matching judgments of distances between all possible pairs of stimuli, obtained from 16 stimuli (in a regular squared 4 x 4 matrix). Two parameters from Stevens' power law informed us about the distortion of visual space: its exponent and its coefficient of determination (R2). The results showed a ranking of the magnitude of the distortions found in each experimental environment, and also provided information about the efficacy of available visual cues of spatial layout. Furthermore, our data are in agreement with previous findings showing systematic perceptual errors, such as the further the stimuli, the larger the distortion of the area subtended by perceived distances between stimuli. Additionally, we measured the magnitude of distortion of visual space relative to physical space by a parameter of multidimensional scaling analyses, the RMSE. From these results, the magnitude of such distortions can be ranked, and the utility or efficacy of the available visual cues informing about the space layout can also be inferred.     

Distance perception in a natural outdoor setting: is there a developmental trend to overconstancy?

The main purpose of the present study was to investigate whether in natural environment, using very large physical distances, there is a trend to overconstancy for distance estimates during development. One hundred and twenty-nine children aged 5 to 13 years old and twenty-one adults (in a control group), participated as observers. The observer's task was to bisect egocentric distances, ranging from 1.0 to 296.0 m, presented in a large open field. The analyses focused on two parameters, constant errors and variable errors, such as measuring accuracy and precision, respectively. A third analysis focused on the developmental pattern of shifts in constancy as a function of age and range of distances. Constant error analysis showed that there are two relevant parameters for accuracy, age, and range of distances. For short distances, there are three developmental stages: 5-7 years, when children have unstable responses, 7-11, underconstancy, and 13 to adulthood, when accuracy is reached. For large distances, there is a two-stage development: 5-11 years, with severe underconstancy, and beyond this age, with mild underconstancy. Variable errors analyses indicate that precision is noted for 7 year-old children, independently of the range of distances. The constancy analyses indicated that there is a shift from constancy (or slightly overconstancy) to underconstancy as a function of physical distance for all age groups. The age difference is noted in the magnitude of underconstancy that occurs in larger distances, where adults presented lower levels of underconstancy than children. The present data were interpreted as due to a developmental change in cognitive processing rather than to changes in visual space perception.
