Lessons from safety-critical sociotechnical systems, such as aviation and acute medical care, demonstrate the importance of the human factor and highlight the crucial role of efficient communication between human agents. Although a large proportion of fatal incidents in aviation have been linked to failures in communication, cognitive engineering provides the theoretical framework to mitigate risks and increase performance in sociotechnical systems not only in the civil sector, but also in the military domain. Conducting cyber operations in multidomain battles presents new challenges for military training and education as the increased importance of psychological factors such as metacognitive skills and perspective-taking both in lower and higher ranking staff, becomes more apparent. The Hybrid Space framework (Jøsok et al., 2016) provides a blueprint for describing the cognitive and behavioral constraints for maneuvering between socio-technical and cyber-physical systems whilst cooperating, coordinating or competing with accompanying cognitive styles in the chain of command. We apply the Hybrid Space framework to communicative challenges in the military cyber domain and suggest a three-phase Orienting, Locating, Bridging model for safe and efficient communication between partners. Based on the educational principles of the Norwegian Defence Cyber Academy, we discuss the required skill-sets and knowledge in which cyber officer cadets are trained and taught early in their education, and how these refer to the theoretical framework of the Hybrid Space and the key principles of communication as defined in cognitive engineering.  相似文献

This study aimed to examine the health-related quality of life (HrQoL), coping, height-related beliefs, and social support of children/adolescents with short stature, the sociodemographic, clinical, and psychosocial variables associated with HrQoL, and the moderating role of sociodemographic and clinical variables on the associations between psychosocial variables and HrQoL. 114 Portuguese children/adolescents with short stature, aged 8–18 years old, completed the Quality of Life in Short Stature Youth questionnaire and the Satisfaction with Social Support Scale. Regression analyses explained 54% of the variance of HrQoL, with significant main effects of current height deviation and height-related beliefs, and a significant interaction effect between beliefs and diagnosis. Results suggest that a multidisciplinary therapeutic approach, not only focused on hormone treatment to boost physical growth, but also including psychosocial interventions focused on the modification of height-related beliefs, may contribute to improve the HrQoL of pediatric patients with short stature.

The relationship between handgrip isometric strength and swimming performance was assessed in the four competitive swimming strokes in swimmers of different age groups and of both sexes. 78 national-level Portuguese swimmers (39 males, 39 females) were selected for this study. Grip strength, previously used as a marker of overall strength to predict future swimming performance, was measured using a hand dynamometer. The best competitive time at 100 and 200 m in all four swimming strokes were converted into 2010 FINA points. Non-parametric tests were used to evaluate differences between groups. Pearson product-moment correlations were computed to verify the association between variables. Handgrip maximum isometric strength was significantly correlated with swimming performance, particularly among female swimmers. Among female age group swimmers, the relationship between handgrip and 100-m freestyle was significant. Handgrip isometric strength seems to be related to swimming performance, especially to 100-m freestyle and in female swimmers. For all other distances and strokes, technique and training probably are more influential than semi-hereditary strength markers such as grip strength.  相似文献

We tested two competing hypotheses-relative social position and community resources-in regards to their effect on two co-occurring health problems (depression, and obesity) in a sample of smokers participating in an online smoking cessation intervention. Income and education data at the zip code level from the 2000 Census was linked with individual level data. Logistic regression models were used for each co-occurring problem to determine how each SES variable (individually and interactively) was associated with the presence of co-occurring health problems. We found that lower individual education was related to poorer health for all outcomes (Depression: OR = 1.25; Obesity: OR = 1.24; Both: OR = 1.46), lower community education was only related to obesity (OR = 1.20). Lower individual income was related to higher rates of depressive symptoms (OR = 1.64) and both health problems (OR = 1.55); a significant interaction of individual and community income (Wald = 6.13, p < .05) revealed that high income individuals were less likely to be depressed if they lived in lower-income communities and became more likely to be so as community income increased. Relative social position was confirmed for depression, whereas community resources were prominent only for obesity. Higher individual education most consistently predicted positive health outcomes, making it a potentially powerful target to reduce health disparities.  相似文献

The electrophysiological correlates of conflict processing and cognitive control have been well characterized for the visual modality in paradigms such as the Stroop task. Much less is known about corresponding processes in the auditory modality. Here, electroencephalographic recordings of brain activity were measured during an auditory Stroop task, using three different forms of behavioral response (overt verbal, covert verbal, and manual), that closely paralleled our previous visual Stroop study. As was expected, behavioral responses were slower and less accurate for incongruent than for congruent trials. Neurally, incongruent trials showed an enhanced fronto-central negative polarity wave (Ninc), similar to the N450 in visual Stroop tasks, with similar variations as a function of behavioral response mode, but peaking ~150 ms earlier, followed by an enhanced positive posterior wave. In addition, sequential behavioral and neural effects were observed that supported the conflict-monitoring and cognitive adjustment hypothesis. Thus, while some aspects of the conflict detection processes, such as timing, may be modality dependent, the general mechanisms would appear to be supramodal.  相似文献

The psychometric properties of a Spanish version of the Muscle Appearance Satisfaction Scale (MASS; Mayville, Williamson, White, Netemeyer, & Drab, 2002) were examined using a sample of five hundred and sixty-one male weightlifters. Exploratory and confirmatory factor analyses suggested that the 19-item Spanish version of the MASS called the Escala de Satisfacción Muscular (ESM), was represented by five subscales similar to the original MASS. Internal consistency of the measure was good (α=.86-.95), and various measures of construct validity indicated that the ESM may be a useful measure of Muscle Dysmorphia symptoms among Spanish speaking populations.  相似文献

Low back problems are associated with decreased quality of life. Specific exercises can improve quality of life, resulting in better professional performance and functionality. The purpose of this study was to evaluate the effect of following a 21-month exercise program on the quality of life of warehouse workers. The population included 557 male warehouse workers from a food distribution company in Oporto, Portugal. Upon application of the selection criteria, 249 workers were deemed eligible, which were randomized into two groups (125 in the intervention group and 124 in the control group). Then, subjects were asked to volunteer for the study, the sample being formed by 229 workers (112 in the intervention group and 117 in the control group). All subjects completed the SF-36 questionnaire prior to beginning the program and on the 11th and 21st months following it. The exercises were executed in the company facilities once a day for 8?min. Data were analyzed using SPSS? 17.0 for Windows?. After 11?months of following the exercise program, there was an increase in all scores for the experimental group, with statistically significant differences in the dimensions physical functioning (0.019), bodily pain (0.010), general health (0.004), and rolephysical (0.037). The results obtained at the end of the study (21?months) showed significant improvements in the dimensions physical functioning (p?=?0.002), rolephysical (p?=?0.007), bodily pain (p?=?0.001), social functioning (p?=?0.015), role-emotional (p?=?0.011), and mental health (p?=?0.001). In the control group all dimensions showed a decrease in mean scores. It can be concluded that the implementation of a low back specific exercise program has changed positively the quality of life of warehouse workers.  相似文献

The purpose of the present study was to examine the psychometric properties of the FACES-IV in Portuguese caregivers of cancer patients. In this cross-sectional study, a sample of 214 adult children caregivers of cancer patients receiving chemotherapy, completed FACES-IV, Family Communication Scale (FCS), Family Satisfaction Scale (FSS), and Satisfaction with Social Support Scale (SSSS). Internal consistencies above .70 were found for all FACES-IV scales, except for Enmeshed and Rigid scales, as well as for the FCS, FSS, and SSSS (except for Intimacy). Strong correlations between FACES-IV and the validation scales FCS and FSS were found except for the Enmeshed and Rigid scales. Confirmatory analysis yielded an acceptable model for the six theoretical subscales. The discriminant analysis between problematic and non-problematic family systems showed results similar to the original study. These findings suggest that FACES-IV is a valid measure of family functioning in oncological family caregiving’s contexts.  相似文献

We investigated Buss and Plomin’s Emotionality Activity Sociability (EAS) Temperament Survey for Children, used to assess temperament. Temperament is believed to comprise stable traits that change little over time. We examined stability of EAS temperament in the Avon Longitudinal Study of Parents and Children, in which 7429 mothers completed the EAS when their children were 3, 5 and 6 years old. Factor analysis was conducted at each time point, and stability over time was assessed using correlation and mixed effects regression modelling, accounting for differences within and between individuals. A four-factor model provided the best fit, with 19–20 of the 20 items loading onto the dimensions predicted by Buss and Plomin. Test–retest correlations ranged from 0.52–0.64 (3–5 years), 0.59–0.74 (5–6 years) and 0.46–0.58 (3–6 years). Mixed effects regression modelling suggested good stability over time: differences between, rather than within, individuals accounted for between 69% and 82% of the variance. This study demonstrates the stability of temperament over time, a vital pre-requisite to investigating childhood temperament as a predictor of outcomes.  相似文献

Oaksford and Chater (1994) proposed to analyse the Wason selection task as an inductive instead of a deductive task. Applying Bayesian statistics, they concluded that the cards that participants tend to select are those with the highest expected information gain. Therefore, their choices seem rational from the perspective of optimal data selection. We tested a central prediction from the theory in three experiments: card selection frequencies should be sensitive to the subjective probability of occurrence for individual cards. In Experiment 1, expected frequencies of the p- and the q-card were manipulated independently by concepts referring to large vs. small sets. Although the manipulation had an effect on card selection frequencies, there was only a weak correlation between the predicted and the observed patterns. In the second experiment, relative frequencies of individual cards were manipulated more directly by explicit frequency information. In addition, participants estimated probabilities for the four logical cases and of the conditional statement itself. The experimental manipulations strongly affected the probability estimates, but were completely unrelated to card selections. This result was replicated in a third experiment. We conclude that our data provide little support for optimal data selection theory.  相似文献
