In der Schweiz leben zwischen 15000 und 16000 Menschen mit HIV/AIDS. Diese Population leidet unter einer Vielzahl von Symptomen und Beschwerden. Besonders schwerwiegend und häufig ist die Fatigue, welche gemäß aktueller Studien bei 20 bis 74% der HIV-infizierten Menschen auftritt. Das Symptom beeinträchtigt alle Aktivitäten des täglichen Lebens, das Empfinden körperlicher und mentaler Gesundheit sowie die Lebensqualität der Betroffenen stark. An der HIV-Sprechstunde des Universitätsspitals Basel, Schweiz, äußern viele Patienten und Patientinnen Beschwerden, die auf das Bestehen von Fatigue hinweisen, oder sprechen direkt über ihre starke Erschöpfung. Eine systematische Literatursuche wurde durchgeführt und ein evidenzbasiertes Praxisprogramm erarbeitet, um den Betroffenen eine angepasste Betreuung bieten zu können. Das Programm enthält die Elemente: Screening, systematisches Assessment, Interventionen und Beratung. Für das Assessment werden der adaptierte Global Fatigue Index und eine visuelle Analogskala eingesetzt. Die Patientinnen werden durch systematische Interventionen bei der Verbesserung ihres Selbstmanagements unterstützt. Ziel der vorliegenden Arbeit ist es, Pflegenden, die HIV-infizierte Menschen betreuen, eine Zusammenfassung der aktuellen Literatur bezüglich HIV-induzierter Fatigue zu präsentieren und die Elemente, den Ablauf sowie des Praxisprogramms darzustellen. Es kann davon ausgegangen werden, dass mit Hilfe des Praxisprogramms Menschen, die mit HIV/AIDS leben und unter Fatigue leiden, positiv beim Management dieses Symptoms ihrer chronischen Erkrankung unterstützt werden können.

Abstract. This article explores the possibility of differentiating between patients suffering from Alzheimer’s disease (AD) and patients with other kinds of dementia by focusing on false alarms (FAs) on a picture recognition task (PRT). In Study 1, we compared AD and non-AD patients on the PRT and found that FAs discriminate well between these groups. Study 2 served to improve the discriminatory power of the FA score on the picture recognition task by adding associated pairs. Here, too, the FA score differentiated well between AD and non-AD patients, though the discriminatory power did not improve. The findings suggest that AD patients show a liberal response bias. Taken together, these studies suggest that FAs in picture recognition are of major importance for the clinical diagnosis of AD.

In recent years, research on cognitive aging increasingly has focused on the cognitive development across middle adulthood. However, little is still known about the long-term effects of intensive job-specific training of fluid intellectual abilities. In this study we examined the effects of age- and job-specific practice of cognitive abilities on detection performance in airport security x-ray screening. In Experiment 1 (N = 308; 24–65 years), we examined performance in the X-ray Object Recognition Test (ORT), a speeded visual object recognition task in which participants have to find dangerous items in x-ray images of passenger bags; and in Experiment 2 (N = 155; 20–61 years) in an on-the-job object recognition test frequently used in baggage screening. Results from both experiments show high performance in older adults and significant negative age correlations that cannot be overcome by more years of job-specific experience. We discuss the implications of our findings for theories of lifespan cognitive development and training concepts.

In line with Whittlesea and Price (2001) , we investigated whether the memory effect measured with an implicit memory paradigm (mere exposure effect) and an explicit recognition task depended on perceptual processing strategies, regardless of whether the task required intentional retrieval. We found that manipulation intended to prompt functional implicit-explicit dissociation no longer had a differential effect when we induced similar perceptual strategies in both tasks. Indeed, the results showed that prompting a nonanalytic strategy ensured performance above chance on both tasks. Conversely, inducing an analytic strategy drastically decreased both explicit and implicit performance. Furthermore, we noted that the nonanalytic strategy involved less extensive gaze scanning than the analytic strategy and that memory effects under this processing strategy were largely independent of gaze movement.

Abstract. Fighter pilots may be exposed to extended flight missions. Consequently, there is increasing concern about fatigue. We investigated the effects of fatigue and cognitive performance in a simulated 11-hr mission in the 39 Gripen fighter aircraft. Five cognitive tasks were used to assess cognitive performance. Fatigue was measured with the Samn–Perelli Fatigue Index. Results showed that performance in the non-executive task degraded after approximately 7 hr. Fatigue ratings showed a matching trend to the performance in this task. Performance in tasks taxing executive functions did not decline. We interpreted that fatigue can be overridden by increased attentional effort for executive tasks but not for non-executive components of cognition. Participants underestimated their performance and metacognitive accuracy was not influenced by fatigue.

This paper presents the application of Gaussian blur filters and Support Vector Machine (SVM) techniques for greeting recognition among the Yoruba tribe of Nigeria. Existing efforts have considered different recognition gestures. However, tribal greeting postures or gestures recognition for the Nigerian geographical space has not been studied before. Some cultural gestures are not correctly identified by people of the same tribe, not to mention other people from different tribes, thereby posing a challenge of misinterpretation of meaning. Also, some cultural gestures are unknown to most people outside a tribe, which could also hinder human interaction; hence there is a need to automate the recognition of Nigerian tribal greeting gestures. This work hence develops a Gaussian Blur – SVM based system capable of recognizing the Yoruba tribe greeting postures for men and women. Videos of individuals performing various greeting gestures were collected and processed into image frames. The images were resized and a Gaussian blur filter was used to remove noise from them. This research used a moment-based feature extraction algorithm to extract shape features that were passed as input to SVM. SVM is exploited and trained to perform the greeting gesture recognition task to recognize two Nigerian tribe greeting postures. To confirm the robustness of the system, 20%, 25% and 30% of the dataset acquired from the preprocessed images were used to test the system. A recognition rate of 94% could be achieved when SVM is used, as shown by the result which invariably proves that the proposed method is efficient.
