Microplastics have been detected in most ecosystems around the world. They affect the environment and organisms in it, including humans and possibly their health. Hence, the analysis of microplastic occurrence in the environment is highly relevant. However, there are only a few practical and easy-to-implement methods published for school use, and therefore, microplastics still receive little attention in the classroom. This review presents an approach for separation and detection of microplastic particles in sediment with secondary school students based on methods used in current research. After sieving and density separation, the fluorescence marker Nile Red is used to selectively stain microplastic particles. Subsequently, the particles can be detected using a DIY low-cost fluorescence photobox. It offers an opportunity to address the problems associated with microplastics in a school context and can be used as an example for further discussion.

This paper presents the outcome of the research project WOODWORKING REVISITED. Within the framework of the two-year project, the two university teams collaborated with the Austrian Open-Air Museum Stübing and the Waldorf Vienna West School to document selected woodworking techniques on video. Formats and dissemination strategies were developed in a collaborative process including pupils and experts at all project stages. The formats were based on established content such as the "Nifty" style found on Buzzfeed (ref.) and further developed for the new immersive possibilities of 360° video. In order to compare the formats and test their efficiency, content produced in both formats was evaluated together with pupils of a technical school for woodworking. The team conducted a study that showed the suitability of both formats for the purpose.

It can be suggested that pre-service primary school teachers' sense of belonging to science may be influential to their professionalization within university-based teacher education programs, which intend to prepare them for teaching natural sciences in primary school. Nevertheless, because only few studies have examined teachers' sense of belonging to science so far, further research in this regard seems both reasonable and necessary. To this end, there is a need for instruments enabling a valid assessment of pre-service primary school teachers' sense of belonging to science. However, existing sense-of-belonging-to-science instruments require a comparatively long time on task due to their significant number of items. Consequently, the applicability of these instruments within research is limited because surveys in educational contexts must often be brief and economical. The research we present in this article aims to tackle this issue by examining on an exploratory level whether and to what extent pre-service primary school teachers' sense of belonging to science can be validly assessed using a single-item instrument. In doing so we report qualitative, as well as quantitative, findings that provide evidence regarding the validity of our instrument. Implications of the present study for future research are outlined at the end of this article.

Research within the context of inclusive education is strongly focused on the investigation of students' special educational needs (SEN). However, a broader understanding of inclusion requires consideration of other factors that may compromise inclusion, especially when it comes to social participation. This study investigates the social participation of 512 students from Austrian secondary mainstream schools. Aside from students' SEN, their migration biography, gender and socio-economic status (SES) were also considered. Students' social participation was measured using peer nominations and peer status. The results indicate that, apart from students with SEN, those with a migration biography and low SES are at risk of low social participation. Amongst the popular students, those with SEN were significantly underrepresented. Regarding peer nominations, students with SEN received less positive and more negative nominations compared to those without SEN. Similar effects for negative nominations were found for students with migration biography and extreme SES. The results suggest that being at risk of low social participation is not only a problem for students with SEN but also a problem for those belonging to minority groups. In terms of research and practical implications (e.g., prevention of the negative outcomes of low social participation), the results of the current study suggest considering student diversity in a broader sense. Furthermore, students from other minority groups, such as those with a migration biography or students from low socio-economic status backgrounds (SES), are likely to suffer from social exclusion.

In this paper, we propose the Social Semantic Server (SSS) as a service-based infrastructure for workplace and professional learning analytics (LA). The design and development of the SSS have evolved over eight years, starting with an analysis of workplace learning inspired by knowledge creation theories and their application in different contexts. The SSS collects data from workplace learning tools, integrates it into a common data model based on a semantically enriched artifact-actor network, and offers it back for LA applications to exploit the data. Further, the SSS design's flexibility enables it to be adapted to different workplace learning situations. This paper contributes by systematically deriving requirements for the SSS according to knowledge creation theories, and by offering support across a number of different learning tools and LA applications integrated into the SSS. We also show evidence for the usefulness of the SSS extracted from 4 authentic workplace learning situations involving 57 participants. The evaluation results indicate that the SSS satisfactorily supports decision making in diverse workplace learning situations and allow us to reflect on the importance of knowledge creation theories for this analysis.

Purpose: The aim of this study is to unveil how professional trainers and training managers describe the learning conditions of their workplaces, what informal and formal learning activities they intend to accomplish and what barriers to learning at work they encounter. Design/methodology/approach: Barriers to learning in the workplace fall under individual, team or organizational aspects that hinder the initiation of or interrupt successful learning, delay proceedings or end learning activities much earlier than intended. Professional trainers (N = 16) and training managers (N = 10) participated in this interview study. Their answers were recorded, transcribed and analyzed via qualitative content analysis. Findings: The participants assessed their work tasks as highly complex and balanced between new challenging tasks and routines. Their formal and informal learning activities were also fundamental to maintaining high performance. The trainers described a broad range of situations in which they suffered barriers to learning at their workplace, with most identifying external learning barriers such as vague supervisor requirements or disruptions from others. Originality/value: The results of this study describe workplace complexity, which offers stimuli for learning through learning conditions, possibilities to engage in learning and also barriers to learning. To understand workplace complexity, all of these dimensions have to be understood and addressed.

A recent Registered Replication Report (RRR) of the development of verbal rehearsal during serial recall revealed that children verbalized at younger ages than previously thought, but did not identify sources of individual differences. Here, we use mediation analysis to reanalyze data from the 934 children ranging from 5 to 10 years old from the RRR for that purpose. From ages 5 to 7, the time taken for a child to label pictures (i.e. isolated naming speed) predicted the child's spontaneous use of labels during a visually presented serial reconstruction task, despite no need for spoken responses. For 6- and 7-year-olds, isolated naming speed also predicted recall. The degree to which verbalization mediated the relation between isolated naming speed and recall changed across development. All relations dissipated by age 10. The same general pattern was observed in an exploratory analysis of delayed recall for which greater demands are placed on rehearsal for item maintenance. Overall, our findings suggest that spontaneous phonological recoding during a standard short-term memory task emerges around age 5, increases in efficiency during the early elementary school years, and is sufficiently automatic by age 10 to support immediate serial recall in most children. Moreover, the findings highlight the need to distinguish between phonological recoding and rehearsal in developmental studies of short-term memory.

This paper explores the linguistic landscape (LL) in the southern Austrian province of Carinthia, which is home to an autochthonous Slovene minority. Following several decades of political and legal debate known as the "Ortstafelstreit" ("dispute of topographic signs"), recent legislation has strengthened the status of Slovene by requiring municipalities with a considerable Slovene population to set up bilingual German-Slovene topographic signs marking their municipal boundaries. However, this is juxtaposed with a longstanding decline in use of the Slovene language amongst the autochthonous Slovene population. This qualitative analysis of the LL of three frames, the civic, the commercial and the church, shows a heterogeneous picture, but one that is generally strongly skewed towards monolingual German. It suggests that Slovene is assigned a comparatively low sociosymbolic value. This can be, at least in part, attributed to the selective manner in which municipalities are awarded legal bilingual status, leading to a lack of linguistic cohesion in the area and its LL. A marked exception to this is the church frame, whose LL is characterised by a relatively balanced use of both German and Slovene.

The first half of the year 2020 has been shaped by quarantines and lock-downs all over the world. The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a pandemic, that slowed down not only social interactions and economy, but also medical and health care. Governments and hospitals were forced to create ad hoc emergency plans maintaining the balance between an adequate participation in collective response of shutting-down to avoid a further spreading of the virus, while preserving the ongoing acute care and simultaneously being able to react to an imminent overextension with a collapse of capacities. The University Hospital Graz is one of the largest hospitals in Austria. As transregional trauma and burn centre it provides care for people from all over Austria and faced special challenges. We present the strategy of the University Hospital Graz in dealing with the COVID-19 pandemic and the way back to (new) normality. The strategy includes infrastructural, patient-centred and staff-centred measures. The continuously low numbers of new infections in Austria allowed a loosening of the lock-down measures already. Particular attention has to be paid to attentive screening of patients and triaging of surgeries during the re-boot. The re-boot needs to be slow and steady to reduce the risk of an infectiological relapse. Once this pandemic is defeated, a careful re-evaluation of the different internationally applied strategies should be performed to be prepared for the future. [ABSTRACT FROM AUTHOR]

In this paper, we evaluate macroeconomic forecasts for Austria and analyze the effects of external assumptions on forecast errors. We consider the growth rates of real GDP and the demand components as well as the inflation rate and the unemployment rate. The analyses are based on univariate measures like RMSE and Theil's inequality coefficient and also on the Mahalanobis distance, a multivariate measure that takes the variances of and the correlations between the variables into account. We compare forecasts generated by the two leading Austrian economic research institutes, the Institute for Advanced Studies (IHS) and the Austrian Institute of Economic Research (WIFO), and additionally consider the forecasts produced by the European Commission. The results indicate that there are no systematic differences between the forecasts of the two Austrian institutes, neither for the traditional measures nor for the Mahalanobis distance. Generally, forecasts become more accurate with a decreasing forecast horizon, as expected; they are unbiased for forecast horizons of less than a year considering traditional measures and for the shortest forecast horizon considering the Mahalanobis distance. Finally, we find that mistakes in external assumptions, in particular regarding EU GDP and the oil price, translate into forecast errors for GDP and inflation. [ABSTRACT FROM AUTHOR]

Highlights • The formation of citizen initiatives remains an unguided and unpredictable process. • Citizens are open to becoming involved in natural hazard management. • Initiatives compensate for perceived injustice and institutional gaps. • Existing social and personal capabilities support formation of initiatives. • Initiatives may trigger reorientation in power sharing. Abstract In the face of increasingly frequent and severe extreme weather events due to climate change, merely top-down governance approaches are increasingly found inadequate and ineffective. Recent climate change adaptation policy strives to promote bottom-up, citizen-driven initiatives to improve local resilience. How and under what conditions citizens may engage in collective action remains unclear, however. We employ a mixed-methods approach in Eastern Tyrol, Austria, combining stakeholder workshops with a survey of 216 citizens at risk. Results show that bottom-up citizen initiatives can provide multiple benefits, such as increasing risk awareness and local adaptive capacities. While citizens are open-minded to assuming a broad range of activities and responsibilities, local stakeholders in natural hazard management prefer to limit civic engagement to support roles, mostly during recovery from a natural hazard event. Citizen initiatives tend to emerge in communities with weak institutional capital. This may lead to conflicts with existing institutions over allocation of competences and power. Contrastingly, social and human forms of capital support the formation of initiatives; however, low willingness of citizens to assume leadership positions may be a bottleneck for sustained initiatives. Public administration and emergency organisations should address current institutional barriers. They should empower and allow citizens to act autonomously. [ABSTRACT FROM AUTHOR]

There is currently no standardized method for reporting audiological, surgical and subjective outcome measures in clinical trials with active middle ear implants (AMEIs). It is often difficult to compare studies due to data incompatibility and to perform meta-analyses across different centres is almost impossible. A committee of ENT and audiological experts from Germany, Austria and Switzerland decided to address this issue by developing new minimal standards for reporting the outcomes of AMEI clinical trials. The consensus presented here aims to provide a recommendation to enable better inter-study comparability. [ABSTRACT FROM AUTHOR]

Per- and polyfluoroalkyl substances (PFAS) are a large group of persistent industrial chemicals that can harm reproductive health. PFAS levels were analysed to determine the current sources of exposure and possible associations between prenatal PFAS exposure and adverse pregnancy outcome. Samples from 136 mother-newborn pairs recruited between 2017 and 2019 were analysed for the presence of 31 target PFAS in maternal serum, umbilical cord serum, and placental tissue by high-performance liquid chromatography coupled to a tandem mass spectrometer. Questionnaires and medical records were used to survey sources of exposure and pregnancy outcome, including small for gestational age (SGA), fetal growth restriction (FGR), preeclampsia (PE), preterm birth, large for gestational age (LGA) and gestational diabetes mellitus (GDM). Data were analysed for individual PFAS and sum4PFAS (sum of perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), perfluorohexane sulfonate (PFHxS), and perfluorooctane sulfonate (PFOS) serum levels) in logistic regression analyses and categorical regression analyses. Compared to data from a previous Viennese study in 2010–12, sum4PFAS levels were generally lower. Sum4PFAS serum levels of three women (2.2%) exceeded 6.9 µg/L, a level that corresponds to the recently established tolerable weekly intake (TWI) of EFSA for nursing mothers aged 35 years; in the 2010/2012 study it was 13.6%. The large contribution of unidentified extractable organofluorine (EOF) fractions to total PFAS exposure is a concern. Study site, mean maternal corpuscular hemoglobin (MCH), use of facial lotion, and owning upholstered furniture were significantly influencing maternal exposure. While no effect of sum4PFAS on pregnancy outcome could be detected, we found highest placental PFDA levels in SGA births. PFHxS levels in umbilical cord and placenta were highest in preterm births. Further studies are needed to elucidate the relationship of prenatal PFAS exposure and pregnancy outcome, in particular to confirm whether and how placental PFDA levels may contribute to an increased risk for SGA. [Display omitted] • 136 mother-newborn pairs were analysed for 31 target PFAS. • Higher PFAS exposure was associated with use of personal care products. • Higher placental PFDA levels were associated with SGA. • PFHxS levels in cord serum and placentas were highest in preterm births.

• Planned relocation is an emerging but underexplored topic in flood risk management. • Households often lack opportunities to express their individual needs. • Policy windows endure over timeframes of several years. • Program implementation overemphasises technical and legal compliance. • Flexibility to personal circumstances and biographical stages increases acceptance. Within the wide array of adaptive responses to flood hazards, planned relocation of residents at risk is usually only taken into account if other responses are ineffective or unavailable. Residents targeted by planned relocation are confronted with radical changes in their livelihood; therefore, relocation is highly contested within public risk discourse. The present paper assesses dynamic processes in the design and implementation of voluntary planned relocation in the Austrian Danube catchment over five decades. Using the Multiple Streams Approach, the emergence of policy windows is mapped to developments in the problem, political, policy and population streams. A mixed-methods design combines semi-structured interviews of 88 affected households and 21 decision-makers with archival research. Repeated flood events underscored that standard protection did not suffice for all riverside communities. In consequence, national authorities acted as policy entrepreneurs to advocate planned relocation and direct the discourse; by contrast, local stakeholders and residents played a mostly passive role. The relocation policy developed from ad-hoc informal arrangements towards a formalised procedure. Relocation governance evolved as incremental change over a long time span instead of immediate, radical disruption. Policy acceptance by residents depended crucially on social learning and on coincidence with personal circumstances and biographical stages. Policy windows opened for several years, when pre-signals from ongoing public debate accumulated and the different timescales in the decision-making of public administrators, elected representatives and residents aligned. Key factors were long-term perspective, flexibility, engagement and social capacity at a local level to deal with and manage planned relocation. [ABSTRACT FROM AUTHOR]

• We interviewed 79 affected residents in a voluntary home buyout scheme. • Relocation decisions involve economic, emotional, social and risk dimensions. • Emotional aspects of fear, uncertainty and place attachment play a critical role. • The importance of decision factors varies between population segments. • Relocation programs should engage in personalized, tailored communication. Planned relocation may permanently reduce exposure to natural hazards; however, residents in designated relocation zones are confronted with a broad array of challenges and face profound changes in their everyday lives. The present study empirically illustrates how economic, emotional, risk and social dimensions underpin household decisions to accept or decline a home buyout offer in a voluntary relocation program in the Eferding Basin, Austria. Semi-structured interviews were conducted with 79 households living in the relocation zone, transcribed and subjected to qualitative content analysis. Risk appraisal and financial feasibility of moving to a new home function as entry points to the decision process. Risk perception is strongly influenced by biographical experiences, traumatic memories, and personal resources to cope with a flood event. Economic reasons are judged in the light of the children's future prospects. Fear and uncertainty about future floods as well as a personal bond to the place are critical emotional factors. By contrast, social relationships play a marginal role because those who leave tend to resettle close-by, and because solitude and autonomy are valued higher than neighborhood networks. Status as a long-term resident, newcomer or elderly person shifts the importance of specific factors, for instance, self-efficacy beliefs or intergenerational considerations. In order to facilitate relocation program implementation, compensation payments should be complemented by communication efforts addressing the emotional and risk dimensions. Communication activities should address those who leave as well as to those who stay and should be tailored to individual needs and resources of residents. [ABSTRACT FROM AUTHOR]

Background: High temperatures at workplaces lead to health-related risks and premature exhaustion. The coronavirus disease 2019 (COVID-19) pandemic requires many health professionals to perform under unfavorable conditions. Personal protective equipment (PPE) causes thermal stress and negatively affects performance., Patients, Materials and Methods: This pilot project investigated the effects of PPE and additional cooling wear on physiological parameters and concentration of six healthy staff members of the Plastic Surgery Department of the Medical University of Graz, Austria during simulated patient care. In this study two 1‑hour cycles with patient care-related tasks with PPE and PPE + cooling-wear, respectively, were conducted. A third cycle with scrubs exclusively served as baseline/negative control. The assessment occurred immediately pre-cycles and post-cycles., Results: Pre-cycle assessments showed no significant differences between the cycles. After PPE cycle, increased physical stress levels and decrements in concentration capacity were observed. Physiological parameters were significantly less affected in the cooling cycle, while concentration capacity slightly increased., Conclusion: COVID-19 PPE causes considerable thermal stress, ultimately affecting human performance. As opportunity to withstand thermal stress, and improve patients' and professionals' safety, cooling-wear can be considered relevant. Medical personnel performing in exceptional situations may particularly benefit from further development and investigation of cooling strategies.
