- PublikationAgeing with HIV in Ghana: an analysis of the age group 50 years plus(Peperosso, 12/2021) Stoller, Nicole; Owusu, Barnabas; Vanderpuye-Donton, Naa Ashiley [in: Journal of HIV and Ageing]Data on HIV amongst the age group 50 years and above are relatively poor in many countries, including sub-Saharan Africa. The main goal of this study was to provide a set of baseline characteristics of older people living with HIV (PLHIV). Furthermore, the study sought to identify whether the analysed characteristics revealed gender disparities. A retrospective analysis of patient data at a private HIV clinic in Ghana was performed. Demographic, behavioural and clinical characteristics of 282 PLHIV aged 50 years or older at their most recent consultation between 2015 and 2019 were selected. Descriptive and inferential statistics were used for analysis. The median age was 56 years, and 57% (162/282) of subjects were female. Sexual activity was confirmed by 44.2% (111/251) of subjects, more frequently by men. Nearly all patients (97.3%, 249/256) were on antiretroviral treatment, and 70.2% (172/245) adhered well. Viral suppression with < 1000 copies/mL was achieved by 63.6% (89/140) of patients, more frequently by women. Non-disclosure of HIV status was reported by 73.5% (191/260) of patients, with more women not having disclosed their status. Our finding of high non-disclosure rates could indicate that stigma and discrimination are amongst one of the biggest challenges for this age group. With regard to the WHO “fourth 90” target, further research is needed to learn more about the health situations and needs of PLHIV aged 50 and over, especially in a geographical area where specific HIV data are sparse.01A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationDeveloping trainings to improve cognitive skills of technical operators in the railway domain(04.12.2020) Wahrstätter, Stefan; Brüngger, Jonas; Stoller, Nicole; Hostettler, Karin; Nisoli, Giulio; Fischer, KatrinTechnical operators in the railway domain are experts responsible for the supervisory control of the traction power network as well as of the railway tunnels. The technical systems used to face these demanding tasks are constantly increasing in their complexity. To carry out this complex activity, it is essential that they have the necessary expertise, not only to master the execution of their own activity under normal conditions, but also to be able to react appropriately to unexpected events. To achieve this, the technical operators must be trained beyond the basic training in which they are educated in terms of technical knowledge and working with guidelines. Trainings to improve the cognitive skills required by technical operators are still lacking in Switzerland. Our team of the University of Applied Sciences Northwestern Switzerland together with a Swiss railway company, in a joint research project, developed trainings to improve the relevant cognitive skills of technical operator in the railway domain. In a first step, we conducted observational interviews to analyze the tasks of technical operators. In a second step, we applied a "Cognitive Task Analysis" (CTA) to identify the cognitive skills that the operators need to perform their tasks. In a third step, we grouped these cognitive skills in order to identify training topics for which the trainings should be developed. The resulting most relevant training topics are: (1) establishing mental models, (2) communication, (3) teamwork, (4) practical rehearsal. For each of these training topics, we defined specific goals that should be achieved by technical operators through the participation to the trainings. All defined goals related to three main categories: knowledge, skills and attitude. Only by considering all three categories, it can be ensured that achieving the goals leads to the theoretical understanding of the desired behavior, the ability and the willingness to really implement it in the work setting. Based on the goals defined for each of the identified training topic, we could finally develop trainings able to improve the relevant cognitive skills of technical operator. For each training topic, we developed two types of trainings: off-the-job trainings and on-the-job trainings. Off-the-job trainings are conceived to be carry out outside of working hours. These include presentations of theoretical content of the training, practical exercises with which the relevant skills can be acquired, and group discussions to support the transfer into the daily work routine. The on-the-job trainings consist of exercises that the technical operators can carry out during their working hours, independently or in consultation with instructors. All taken together, the participation to these trainings allows technical operators to achieve the defined goals, making sure that the relevant cognitive skills of their job are effectively trained.06 - Präsentation
- PublikationUse of modern communication devices in the train driver's cab – risks and design options(02.12.2020) Stoller, Nicole; Nisoli, Giulio; Brüngger, Jonas; Wahrstätter, Stefan; Dittrich, Melisa; Hostettler, Karin; Fischer, KatrinMost Swiss railway companies equip their train drivers with modern digital communication devices such as cell phones and tablets. The use of these devices is necessary for train drivers to perform their tasks but has a potential for distraction that should not be underestimated. Increasing irregularities and unsafe actions, including the signals passed at danger, can be attributed at least to a certain extent to the distraction of the train driver by these mobile and other digital devices in the driver's cab. In a research project conducted by the University of Applied Sciences Northwestern Switzerland together with a Swiss railway company, we investigated which of these digital devices and functions lead to distraction in which situations. Based on this investigation, we analyzed how this problem should be addressed from a work psychology and design perspective. The final goal was to identify appropriate measures to reduce distraction or its consequences without restricting the scope of action of the train drivers or hindering them in the performance of their primary tasks (i.e. safe train driving). In a qualitative approach, we conducted observations of train driving in the driver’s cab and interviews with train drivers and experts. Based on the data obtained and on to the current literature, we conceived the first measures. In order to achieve a comprehensive approach, we developed measures that address the individual train driver as well as measures to improve the design of technology and organizational measures. In a further step, in workshops with other railway professional groups, we discussed and completed these measures in terms of their effectiveness and practicability. The result was a set of 26 preventive and protective measures. Preventive measures have the goal of avoiding distraction, whereas protective measures are conceived to reduce the negative consequences of distraction. While a preventive measure is for e.g. the introduction of attention trainings where train drivers learn to avoid certain distractions, a protective measure is for e.g. the feature of manual and temporary suppression of incoming messages which lead the driver to be distracted by messages but for a shorter duration. By carefully selecting and implementing these measures, the railway company can ultimately support its train drivers in the safe and sensible use of modern communication devices in the driver's cab.06 - Präsentation
- PublikationNutzung mobiler digitaler Kommunikationsmittel im Führerstand. Risiken, Nebenwirkungen und Gestaltungsoptionen(03/2020) Stoller, NicoleIm Führerstand von Zügen werden heute immer mehr mobile Kommunikationsmittel wie Smartphones und Tablets genutzt. Teils ist die Nutzung dieser Geräte für die Aufgabenausführung notwendig, teils bergen diese Geräte ein nicht zu unterschätzendes Ablenkungspotenzial. Immer häufiger kommt es zu Unregelmäßigkeiten und unsicheren Handlungen, die mindestens mitbedingt sind durch Ablenkungen aufgrund von Smartphone- oder Tabletnutzung. In einem Forschungsprojekt wurde zusammen mit einem Schweizer Bahnunternehmen untersucht, welche dieser Kommunikationsmittel in welchen Situationen ablenkend wirken und wie man arbeitspsychologisch mit diesem Problem umgehen sollte. Aus der Analyse wurden präventive und protektive Maßnahmen entwickelt, um künftig Unregelmäßigkeiten aufgrund von Ablenkung zu verhindern bzw. zu reduzieren.06 - Präsentation
