This paper addresses one important mechanism through which the EU tries to improve the operation of its labour markets: the opening up of national borders for free worker movement within the EU. Free worker movement is a fundamental EU right; but EU enlargement begged the question of how and when to allow complete free movement to workers from those new Member States. The EU agreed upon a transitional period of up to 7 years after accession of eight new Middle and Eastern European States (EU-8) on May 1st, 2004. Duringthis transitional period Member States may apply certain restrictions on the free movement of workers from, to and between these new Member States. By 2012, all such restrictions will have been abolished. A similar procedure applies regarding the accession of two additional new Member States on January 1st, 2007. Only three of the fifteen incumbent EU Member States at the time (EU-15) chose to immediately allow free movement from workers from the EU-8. The other twelve maintained their work permit systems, albeit with some modifications. Since, some (e.g. Germany) have already decided to keep such barriers in place until 2012. The Netherlands has kept a work permit system in place up to May 1st, 2007. At that time it abolished that system and effectively extended free worker movement to include workers from the EU-8. This makes the Dutch case, at this point in time, an interesting case for which to analyse the process and effects of increased free labour movement into a national labourmarket. This paper discusses the evolution of (temporary) work migration from EU-8 countries into the Netherlands. It first addresses the flexicurity nature of EU policies towards labour market integration and towards the inclusion of new EU countries in that process. It subsequentely reviews the three socio-legal regimes that can currently apply to work performed for Dutch firms Netherlands by workers from the EU-8 (which, now, is that same as that applies for workers from the EU-15): wage employment; employment through temporary employment agencies; and self-employment. It then discusses the development of the volume of work performed by citizens from the EU-8 in the Netherlands, and socio-economic effects for both the migrant workers and Dutch society and economy. It concludes with a discussion of challenges (or the lack thereof) that this increased free movement of foreign labour caused and causes for Dutch institutions.
Background: Computed tomography (CT) is one of the most used modalities for diagnostics in paediatric populations, which is a concern as it also delivers a high patient dose. Research has focused on developing computer algorithms that provide better image quality at lower dose. The iterative reconstruction algorithm Sinogram-Affirmed Iterative Reconstruction (SAFIRE) was introduced as a new technique that reduces noise to increase image quality.Purpose: The aim of this study is to compare SAFIRE with the current gold standard, Filtered Back Projection (FBP), and assess whether SAFIRE alone permits a reduction in dose while maintaining image quality in paediatric head CT.Methods: Images were collected using a paediatric head phantom using a SIEMENS SOMATOMPERSPECTIVE 128 modulated acquisition. 54 images were reconstructed using FBP and 5 different strengths of SAFIRE. Objective measures of image quality were determined by measuring SNR and CNR. Visual measures of image quality were determined by 17 observers with different radiographic experiences. Images were randomized and displayed using 2AFC; observers scored the images answering 5 questions using a Likert scale.Results: At different dose levels, SAFIRE significantly increased SNR (up to 54%) in the acquired images compared to FBP at 80kVp (5.2-8.4), 110kVp (8.2-12.3), 130kVp (8.8-13.1). Visual image quality was higher with increasing SAFIRE strength. The highest image quality was scored with SAFIRE level 3and higher.Conclusion: The SAFIRE algorithm is suitable for image noise reduction in paediatric head CT. Our data demonstrates that SAFIRE enhances SNR while reducing noise with a possible reduction of dose of 68%.
Low heart rate variability (HRV) is related to health problems that are known reasons for sick-leave or early retirement. A 1-minute-protocol could allow large scale HRV measurement for screening of health problems and, potentially, sustained employability. Our objectives were to explore the association of HRV with measures of health. Cross-sectional design with 877 Dutch employees assessed during a Workers’ Health Assessment. Personal and job characteristics, workability, psychological and mental problems, and lifestyle were measured with questionnaires. Biometry was measured (BMI, waist circumference, blood pressure, glucose, cholesterol). HRV was assessed with a 1-minute paced deep-breathing protocol and expressed as mean heart rate range (MHRR). A low MHRR indicates a higher health risk. Groups were classified age adjusted for HRV and compared. Spearman correlations between raw MHRR and the other measures were calculated. Significant univariable correlations (p < 0.05) were entered in a linear regression model to explore the multivariable association with MHRR. Age, years of employment, BMI and waist circumference differed significantly between HRV groups. Significant correlations were found between MHRR and age, workability, BMI, waist circumference, cholesterol, systolic and diastolic blood-pressure and reported physical activity and alcohol consumption. In the multivariable analyses 21.1% of variance was explained: a low HRV correlates with aging, higher BMI and higher levels of reported physically activity. HRV was significantly associated with age, measures of obesity (BMI, waist circumference), and with reported physical activity, which provides a first glance of the utility of a 1-minute paced deep-breathing HRV protocol as part of a comprehensive preventive Workers’ Health Assessment.Open Access This article is distributed under the terms of the Creative Commons Attribution 4.0 International License (http://creat ivecommons .org/licen ses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate redit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

Mycelium biocomposites (MBCs) are a fairly new group of materials. MBCs are non-toxic and carbon-neutral cutting-edge circular materials obtained from agricultural residues and fungal mycelium, the vegetative part of fungi. Growing within days without complex processes, they offer versatile and effective solutions for diverse applications thanks to their customizable textures and characteristics achieved through controlled environmental conditions. This project involves a collaboration between MNEXT and First Circular Insulation (FC-I) to tackle challenges in MBC manufacturing, particularly the extended time and energy-intensive nature of the fungal incubation and drying phases. FC-I proposes an innovative deactivation method involving electrical discharges to expedite these processes, currently awaiting patent approval. However, a critical gap in scientific validation prompts the partnership with MNEXT, leveraging their expertise in mycelium research and MBCs. The research project centers on evaluating the efficacy of the innovative mycelium growth deactivation strategy proposed by FC-I. This one-year endeavor permits a thorough investigation, implementation, and validation of potential solutions, specifically targeting issues related to fungal regrowth and the preservation of sustained material properties. The collaboration synergizes academic and industrial expertise, with the dual purpose of achieving immediate project objectives and establishing a foundation for future advancements in mycelium materials.
