This paper examines how occupational groups survive the introduction of a new technology and associated jurisdictional changes. We draw on a comparative historical analysis of two occupational associations'—systems men and production planners—efforts to frame their evolving tasks and relate to other occupations after the introduction of the computer into U.S. business in the early 1950s. We observe that systems men followed the path traditionally advocated in the occupations and professions literature by seeking autonomy through differentiating their task domains from other groups and by trying to get other groups to recognize their control. But they were unsuccessful and disbanded by the mid-1990s. In contrast, the successful production planners took an integrative approach through efforts to frame the interdependencies of their tasks and relate to other occupations, making them more necessary to the functioning of other groups and the organization. Our study contributes to the growing relational perspective on occupations by showing how taking an integrative approach with other occupations at the field level can help occupations survive long term.

In the European Union, health surveillance (HS) of electromagnetic fields (EMF)-exposed workers is mandatory according to the Directive 2013/35/EU, aimed at the prevention of known direct biophysical effects and indirect EMF's effects. Long-term effects are not addressed in the Directive as the evidence of a causal relationship is considered inadequate. Objectives of HS are the prevention or early detection of EMF adverse effects, but scant evidence is hitherto available on the specific procedures. A first issue is that no specific laboratory tests or medical investigations have been demonstrated as useful for exposure monitoring and/or prevention of the effects. Another problem is the existence of workers at particular risk (WPR), i.e., subjects with specific conditions inducing an increased susceptibility to the EMF-related risk (e.g., workers with active medical devices or other conditions); exposures within the occupational exposure limit values (ELVs) are usually adequately protective against EMF's effects, but lower exposures can possibly induce a health risk in WPR. Consequently, the HS of EMF-exposed workers according to the EU Directive should be aimed at the early detection and monitoring of the recognized adverse effects, as well as an early identification of WPR for the adoption of adequate preventive measures.

Magnetic resonance (MR) systems are used in academic research laboratories and industrial research fields, besides representing one of the most important imaging modalities in clinical radiology. This technology does not use ionizing radiation, but it cannot be considered without risks. These risks are associated with the working principle of the technique, which mainly involves static magnetic fields that continuously increase—namely, the radiofrequency (RF) field and spatial magnetic field gradient. To prevent electromagnetic hazards, the EU and ICNIRP have defined workers' exposure limits. Several studies that assess health risks for workers and patients of diagnostic MR are reported in the literature, but data on workers' risk evaluation using nuclear MR (NMR) spectroscopy are very poor. Therefore, the aim of this research is the risk assessment of an NMR environment, paying particular attention to workers with active implantable medical devices (AIMDs). Our perspective study consisted of the measurement of the static magnetic field around a 300 MHz (7 T) NMR research spectrometer and the computation of the electric field induced by the movements of an operator. None of the calculated exposure parameters exceeded the threshold limits imposed by legislation for protection against short-term effects of acute occupational exposure, but our results revealed that the level of exposure exceeded the action level threshold limit for workers with AIMD during the execution of tasks requiring the closest proximity to the spectrometer. Moreover, the strong dependence of the induced electric field results from the walking speed models is shown. This case study represents a snapshot of the NMR risk assessment with the specific goal to increase the interest in the safety of NMR environments.

Mittels einer Mitgliederanalyse der organisierten Soziologen im Berufsverband Deutscher Soziologen e.V. geht der Beitrag professionssoziologischen Fragestellungen nach und versucht Aussagen zu den verschiedenen Beschäftigungsfeldern der Soziologen zu gewinnen. Über die Mitgliederdatenbank lassen sich die regionale Verteilung der Mitglieder, die Zahl der ordentlichen und außerordentlichen Mitglieder und die Geschlechterproportion ablesen. Hinsichtlich der Berufstätigkeit der Mitglieder läßt sich feststellen, daß von den 511 Mitgliedern etwa 28,3 v.H. derzeit ohne Beschäftigung sind und von dem Rest fast jedes dritte Mitglied in Forschung und Lehre tätig ist. Was die Interessengebiete angeht, liegt der Schwerpunkt eindeutig auf den Methoden der Sozialforschung. Beim Interesse für Berufsfelder läßt sich eine Präferenz für die Jugend- und Sozialarbeit sowie für Beratungsberufe verzeichnen. Um zu tiefergreifenden Aussagen gelangen zu können, müßte die Mitgliederanalyse durch eine gesonderte Befragung ergänzt werden. (ICH)

Workplace accident and disease prevention have been the focus of law-making activity in European Union (EU) since the creation of the common market. In more than half a century, the EU occupational health and safety (OHS) law grew from nothing into the present legal system, experiencing stages of development through the introduction of important European Community (EC) treaties, for example, the Rome Treaty, Paris Treaty, Maastricht Treaty, Lisbon Treaty and other European-wide legal documents such as the European Social Charter 1961, and seven rounds of EU enlargements for the accession of new member states. With these developments, the approaches adopted in EU OHS law are also involving. In the first few decades, a prescriptive approach was dominant until the introduction of the Framework Directive 89/391, which marked the shift towards a goal-oriented approach. In the later development, the evolution in approach also presents a shift towards the social dialogue approach.

Abstract
Low-cost particulate matter sensors are a up-and-coming technology for monitoring occupational exposure to hazardous substances in high spatial and temporal resolutions. Low costs, small sizes and high measurement frequencies offer the potential to continuously, automatically and remotely measure dust exposure and emission in the workplace. However, much remains unknown about how these devices can be successfully applied in occupational settings. TNO (the Netherlands) has, in collaboration with HSE (UK) and NIOSH (US), performed field studies at seven companies in the bakery, woodworking and welding industry to explore the use of sensors. A total of 145 full / half-shift measurements were collected for 37 workers and 15 static positions. Measurement data was obtained using four types of sensor and conventional respirable gravimetric and high-resolution reference devices. High-resolution contextual information was collected using additional sensors, including an ultrasound-based indoor positioning system, to investigate how these can further characterize exposure situations. Sensor accuracy compared to reference measurements ranged up to R2-values of 0.92, but large variations were observed within and between industries. Overall, stationary measurements showed less variation in performance compared to personal measurements. Different types of sensor seemed more accurate for specific industries. Contextual measurements provided additional information on when and where exposure occurred, for example by dynamic hazard maps based on indoor location and personal sensor measurements. Although performance of sensors remains lower than conventional methods, they may provide accurate measurements in specific situations. Additionally, sensors can provide new types of information that cannot be captured by time-integrated measurements.

Context: Dual VET systems are often praised for their labour market proximity because of economic stakeholders' involvement. However, when labour market requirements change rapidly, a lack of flexibility is attributed to them. This occurs in times of fast socio-technological change like the current digital transformation. A repeatedly proposed measure to increase system flexibility is to reduce the number of occupations and create broader occupational profiles, for example, by combining similar occupations into so-called occupational fields. However, little is known about actually establishing occupational fields. Approach: Against this backdrop, we address the following research question: How was an occupational field created? As Switzerland attempted to merge occupations over a decade ago, we selected an information-rich and illuminative case concerning the research question: The piano makers' occupation as one of the first occupations required to merge into an occupational field called musical instrument makers together with organ builders and wind instrument makers. Based on a qualitative case study, we reconstruct the process of occupational field construction by combining expert interviews with comprehensive document analysis and present its narrative. Findings: Based on this case study, we contribute to the understanding of VET flexibilisation by detailing occupational field creation and identifying opportunities and challenges. Here, we pay special attention to the institutional work of the affected occupational association and identify the importance of preserving its collective occupational identity. Although regulatory changes disrupted the piano makers' occupation, the occupational association reinstitutionalised it as part of the musical instrument makers' occupational field. Over a decade later, the piano makers reintroduced their former occupational title, which is deeply connected to their occupational identity. Conclusion: The results indicate that VET reforms that promote flexibilisation by creating occupational fields encounter serious limitations in collectively governed dual VET systems. In the Swiss system, occupational associations are core collective actors that rely on their members' voluntary work. To maintain these economic stakeholders' necessary commitment to VET, their collective occupational identity, symbolized by their long-standing occupational title, needs to be preserved.
